Description

Technical Field

[0001] The utility model relates to the technical field of water glass filter pressing, in particular to a device for reducing the amount of wet water glass filter residue entering a storage tank. Background Art

[0002] At present, the normal filter press process for water glass is: open the discharge valve of the reactor, the slurry enters the transfer mixer, start the filter press pump on the mixer, the slurry is pumped to the filter press, the filtrate, i.e. the water glass, enters the receiving trough, and then falls into the transfer box below it, start the slurry pump on the transfer box, and the water glass is pumped into the storage tank for storage;

[0003] However, since most of the wet water glass is filtered using a plate and frame filter press, if there is a problem in cleaning the filter residue or the aluminum plate or filter cloth before filtration, the water glass after filtration will be mixed with some of the filter residue and enter the transfer box under the filter press, and then be transported to the storage tank by the mud pump. If this continues for a long time, it will cause the storage tank to be silted up and the effective volume to be reduced. At the same time, the storage tank is a limited space and is difficult to clear.

[0004] Therefore, the utility model proposes a device for reducing the amount of wet-process water glass filter residue entering into a storage tank. Utility Model Content

[0022] The transfer mixer 2 includes a tank body 21, and a motor 22 is fixedly connected to the top wall of the tank body 21, a main shaft 23 is installed at the bottom driving end of the motor 22, the bottom end of the main shaft 23 passes through the top wall of the tank body 21 and extends to the inside of the tank body 21, a plurality of cross bars 24 are fixed to the side wall of the main shaft 23, the other ends of the plurality of cross bars 24 are fixedly connected to a shaft sleeve 25, a side shaft 26 is rotatably connected inside the shaft sleeve 25, and a stirrer 27 is fixedly connected to the side shaft 26 and the bottom end of the main shaft 23.

[0023] When the transfer mixer 2 is working, the motor 22 is started to drive the main shaft 23 to rotate. The main shaft 23 drives the stirrer 27 at the bottom thereof to rotate, and at the same time drives the cross bar 24 and the side shaft 26 to revolve in the tank body 21.

[0024] A gear 28 is fixedly connected to the top end of the side shaft 26 , an inner gear ring 29 is fixedly connected to the inner wall of the tank body 21 , and the gear 28 meshes with the inner gear ring 29 .

[0025] Since the gear 28 at the top of the side shaft 26 meshes with the inner gear ring 29, the side shaft 26 will also drive the stirrer 27 at the bottom to rotate, and the slurry in the tank body 21 can be stirred by the main shaft 23 and the stirrer 27 at the bottom of the side shaft 26 at the same time, which can improve the stirring efficiency.

[0026] A discharge valve 61 is fixedly installed in the middle of the discharge pipe 6.

After being stirred by the transfer mixer 2, the stirred raw materials are pumped to the plate and frame filter press 3 for filtration through the filter press pump 7. The filtrate (i.e., water glass) enters the receiving trough and then falls into the transfer box 4 below it along the receiving trough. At this time, open the valve on the bypass pipe 83, close the valve on the second liquid discharge pipe 82, and pump the slurry in the transfer box 4 back to the transfer mixer 2 under the action of the mud pump 8. After several filtration cycles, until the slurry in the transfer box 4 meets the requirements, close the valve on the bypass pipe 83, open the valve on the second liquid discharge pipe 82, and allow the slurry to enter the storage tank 5 for storage.
