Decanter centrifuge manufacturer's guidance on its two major aspects of operation

I believe everyone is familiar with decanter centrifuges, but it may not be clear to everyone how to use them correctly and reasonably. Therefore, in order to achieve this goal, the following will focus on some of its specific issues, to expand the discussion, in order to have a good learning effect.

To summarize and summarize some issues in the centrifuge:

    1. Before using the decanter centrifuge

        (1) At this point, the recommendation given by the decanter centrifuge manufacturer is that the centrifuge should be placed on a tight and horizontal plane to ensure a good centrifugal effect and ensure safe use.

        (2) No items can be placed on the door. Moreover, the samples should be placed symmetrically. In addition, check whether the nut is tightened.

        (3) For the rotor in the decanter centrifuge, check whether it has problems such as corrosion and scars, as well as whether there are cracks and aging problems in the centrifuge cup. If there is, the centrifuge cannot be used and should be handled by professionals immediately.

        (4) For the compression nut on the decanter centrifuge, it is necessary to check whether it is tightened to prevent it from flying out and hurting people when the centrifuge is running at high speed.

         2. Decanter centrifuge in use

In this regard, the instructions given by the decanter centrifuge manufacturer are mainly:

        (1) The rotation speed of the centrifuge during operation must not exceed the specified range, so as to ensure the safety of the equipment.

        (2) If there is an abnormality in the speed, the machine should be shut down immediately, without delay.

        (3) It is not allowed to open the centrifuge door while the equipment is in operation, because it is very dangerous and unsafe.

    In addition to the above, what needs to be supplemented is that the centrifuge must be filled in the same amount. If the rotor is unbalanced, it cannot run. In addition, in terms of running time, it cannot exceed 60 minutes at a time, because too long time will cause problems.

Will there be confusion in the purchase and use of a decanter centrifuge?

Decanter centrifuge is not only one of the types of centrifuges, but also one of the keywords of the website. Therefore, in order to familiarize yourself with the website and the manufacturer of the horizontal centrifuge, Chengdu Zhikai Separation, the following will continue with the decanter centrifuge The learning of this kind of centrifuge can well achieve the above-mentioned purpose.

1. Using a decanter centrifuge to treat sludge, how to get the water content before and after the sludge treatment, or during the treatment process?

If you use a decanter centrifuge to treat the sludge, then the water content of the sludge before and after or during the treatment can be detected by using the sludge moisture content rapid tester, and Get specific values. Moreover, in addition to detecting the water content of the sludge, it can also detect the solid content of the sludge. The operation is also very simple and convenient.

2. When buying a decanter centrifuge, will there be a corresponding product manual?

When purchasing a centrifuge product, a decanter centrifuge, generally speaking, the manufacturer will improve the operation and user manual of the product, so the answer to this question is yes. Moreover, in addition to the corresponding manuals, the manufacturer will also inform users of some precautions during the trial operation of the centrifuge, and will send professionals to provide professional guidance to allow users to operate and use the centrifuge products correctly.

3. If the idling current of the decanter centrifuge is large, or there is abnormal noise during operation, then what is the reason? 　Decanter centrifuge, if the current is too large when idling, then it is because there is material inside the centrifuge This problem is caused by accumulation or incomplete cleaning. If there are abnormal noises during operation, it indicates that the differential in the centrifuge is faulty or the parts are not installed in place. Therefore, it is necessary to investigate one by one to find out the real cause, and then it can be effectively solved.

What are the methods of using sludge treatment equipment

The treatment method of the sludge treatment equipment, first, the original sludge is pumped from the secondary settling tank to another tank through the sludge pump and then separated from the supernatant. Since the moisture content of the original sludge can generally reach 99.5%, it is necessary to thicken the sludge. There are many feasible ways to reduce the volume of the sludge.

　　 Mechanical treatment methods such as vacuum filtration and centrifugation are generally used before the sludge is disposed of in a semi-solid manner. Generally these methods are preparations for sludge combustion treatment. If biological treatment is planned, gravity sedimentation or air flotation is mostly used for concentration. The sludge corresponding to these two cases is still fluid.

　　 The design and operation of the gravity thickening tank are similar to the secondary settling tank in sewage treatment. The concentration function is the main design parameter. In order to satisfy the greater concentration capacity, the concentration tank is basically deeper than the secondary settling tank. A properly designed and well-functioning gravity thickener can increase the sludge content by at least twice. In other words, the moisture content of sludge can be reduced from 99.5% to 98% or less. It is worth mentioning here that the design of the gravity thickening tank should be based on the analysis of Chinese results as much as possible, because the appropriate sludge loading rate is closely related to the properties of the sludge.

　　 If dissolved air flotation is used for concentration, a small amount of water is required, usually from the secondary sedimentation tank, and aerated at a pressure of 400kPa. This supersaturated liquid passes into the bottom of the tank, while the sludge passes under atmospheric pressure. The gas adheres to the solid particles in the sludge in the form of small bubbles, or is enclosed, and then drives the solid particles to float to the surface. The upper part of the concentrated sludge is removed, and the liquid flows from the bottom back to the gas tank for aeration.

The structure introduction of the decanter centrifuge

　　 Decanter centrifuge is a model with low energy consumption, stable function and good separation effect. Widely used in the chemical, food, salt, mining, pharmaceutical and other industries (for the separation of dozens of materials, because of the successful application experience, you can communicate with technicians when selecting models to obtain more detailed materials). In the separation process, the feeding, dewatering, washing, unloading and other processes are continuously completed, and the production efficiency and automation are high. It is an advanced separation equipment.

　　Because of its separation principle and structural characteristics, it is also highly specific to materials. Material analysis and corresponding experiments should be carried out when selecting models to confirm its applicability and separation function.

　　 The solid particles with a larger specific gravity are deposited on the inner wall of the rotating drum in the decanter centrifuge. The screw sedimentation centrifuge is a kind of mud-water mixture that enters the rotating drum through the feed pipe and the screw discharge port. Under the action of centrifugal force generated by the high-speed rotation of the host. The spiral blades moving relative to the drum continuously scrape the solid particles deposited on the inner wall of the drum and push them out of the slag discharge port, and the separated clear liquid flows out of the drum machine through the weir plate opening.

　　 The working principle of the decanter centrifuge is that the mud-water mixture enters the drum through the feed pipe and the screw discharge port. Under the action of the centrifugal force generated by the high-speed rotation of the host, solid particles with a larger specific gravity are deposited on the inner wall of the drum.

The spiral blades of the decanter centrifuge and the rotating drum move relative to each other to continuously scrape the solid particles deposited on the inner wall of the rotating drum and push them out of the slag discharge port. The separated clear liquid flows out of the drum through the opening of the weir plate. The relative movement between the screw and the drum is completed by the differential, the shell of the differential is connected with the drum, the output shaft is connected with the screw, and the input shaft is connected with the auxiliary motor. When the main motor rotates the drum, it also rotates the differential housing. Because the input shaft is connected to the auxiliary motor, the auxiliary motor generates a braking torque, and then drives the planetary gear to work according to the designed transmission connection, and press A certain proportion of contact transfers the torque to the screw, which completes the continuous separation of materials by the decanter centrifuge.
