Regarding the use of top and bottom valves
Thread Content
Recently, the company wants to switch from manual feeding to a closed feeding method. The idea is as follows: The material is dehydrated and washed in the two-in-one unit; after washing and pressing it dry, it used to be unloaded into a silo before being manually fed into the reactor. Now, after the material has been dehydrated, washed, and pressed dry, water is added directly in that same unit (the material does not dissolve but remains in a paste form), and then it is pumped into the reaction tank. The problem here is a clogged pipe. Especially at the pump’s suction inlet, since compressed air is used to dry out the material, it seals the pipe opening tightly, making it difficult to clear. I wonder if anyone has any good suggestions? Can the top and bottom valves play a key role?
No way, the bottom valve can’t get clogged. It’s a slurry-like material – I don’t know how large the particles are You might consider a slurry pump; it’s a test for the pump
The material is not in the tank; for the two-in-one type, the discharge occurs from the side, rather than vertically downward.
I’m not entirely familiar with the specific characteristics of your materials; personally, I suggest making improvements from the following aspects: 1. As mentioned on the second floor, select an appropriate transfer pump； 2. It is necessary to determine whether the pump inlet is blocked during transportation or after it has completed transportation ； If there is a blockage during transportation, the improvement measures need to be reconsidered ； If it is blocked at the end of transportation ； The following reasons may exist ； At the end of the process, stirring is no longer possible; since some materials settle and cause blockages, it is necessary to reduce the speed of stirring ； Or add water again to dilute the material when it is below the conveying and mixing level ； This might possibly improve the cause of the blockage ； Or add a water pipe to the pump inlet pipeline ； Water is added to the pipeline for cleaning once the material transfer is nearly complete ；
