Abstract

The utility model provides an airflow deslagging device of a sheet frame vacuum filter. The airflow deslagging device mainly comprises an air pipe connecting member (1), a main pipe (2), a branch pipe I (3), a branch pipe II (4), a sludge conveying pump (5), a valve I (6), a valve II (7), a tee joint (8) and a liquid receiving tray (9), wherein the main pipe is laid on the edge of the liquid receiving tray, the air pipe connecting member is connected with the branch pipe I for conveying air, the sludge conveying pump is connected with the branch pipe II for conveying sludge, the two branch pipes are connected and joined to the main pipe through the tee joint, and the valves are arranged on the corresponding branch pipes for controlling branch pipe switches. When sludge is fed in the airflow deslagging device, the valve I is closed, the sludge is fed into the branch pipe II, when the sludge is fed completely, the valve II is closed, the valve I is opened to start ventilating, sludge remained in a pipeline impacts and enters the sheet frame vacuum filter by using the pressure of the air, and the pressure of the air can accelerate the dewatering of the sludge. After dewatering is completed, by using an air pressure cleaning device, the dry deslagging is realized, and the efficiency is increased.

Description

A kind of air-flow slag-draining device of sheet frame vacuum filter

Technical field

The utility model relates to a kind of air-flow slag-draining device of sheet frame vacuum filter.

Background technology

The sheet frame vacuum filter of present adopts wet-process deslagging, by high-pressure water pipe, carries out deslagging.Adopt wet-process deslagging to have very high requirement to operation field, must be arranged near water source, residual body refuse is few, but wants a large amount of water to rinse, cause the utilization rate of water not high, and in flushing process, cause muddy water to splash, pollute operation field, and there is a large amount of mud to residue in pipeline in the process of mud conveying, not only affect into mud effect, blocking pipe, but also be unfavorable for cleaning.

Summary of the invention

The utility model provides a kind of air-flow slag-draining device of sheet frame vacuum filter.It can solve the problem of present wet method sheet frame vacuum filter slag-draining device.Extend the service life of shower nozzle, saving water resource, reduces operating condition, and pressure can also be provided, and accelerates dehydration, raises the efficiency.

The utility model is achieved in that a kind of air-flow slag-draining device of sheet frame vacuum filter, and it is mainly comprised of tracheae connector (1), supervisor (2), No. 1 arm (3), No. 2 arms (4), sludge delivery pump (5), No. 1 valve (6), No. 2 valves (7), threeway (8) and liquid dish (9).Supervisor's lay is in liquid dish edge, and tracheae connector connects No. 1 arm and carries gas, and sludge delivery pump connects No. 2 arms and carries mud, article two, arm is connected and is compiled in supervisor by threeway, and No. 1 arm is installed No. 1 valve, No. 2 arm connects No. 2 valves, and valve is controlled the switch of arm.When device enters mud, close valve No. 1, close tracheae, device enters mud by No. 2 arms, when entering mud and complete, closes valve No. 2, stop into mud, open No. 1 valve and start ventilation, utilize the pressure of gas that mud residual in pipeline is impacted and enters sheet frame vacuum filter, and the pressure of gas can accelerate sludge dehydration.After completing dehydration, this passage is still current, utilizes gas purifier, realizes dry deslagging.

Adopt this device to realize the dry deslagging of sheet frame vacuum filter, it extends the service life of shower nozzle without high pressure water washing, and saving water resource reduces operating condition, and pressure can also be provided, and accelerates dehydration, raises the efficiency.

Accompanying drawing explanation

Fig. 1 is pictorial diagram of the present utility model.

The specific embodiment

Shown in Fig. 1, mainly by tracheae connector (1), supervisor (2), No. 1 arm (3), No. 2 arms (4), sludge delivery pump (5), No. 1 valve (6), No. 2 valves (7), threeway (8) and liquid dish (9), formed.Supervisor's (2) lay is in liquid dish (9) edge, tracheae connector (1) connecting branch (3) is carried gas, sludge delivery pump (5) connecting branch (4) is carried mud, article two, arm is connected and is compiled in supervisor (2) by threeway, and No. 1 arm (3) is installed No. 1 valve (6), No. 2 arms (4) connect No. 2 valves (7), and valve is controlled the switch of arm.When device enters mud, close No. 1 valve (7), close tracheae, device enters mud by No. 2 arms (4), when entering mud and complete, closes No. 2 valves (7), stop into mud, open No. 1 valve (6) and start ventilation, utilize the pressure of gas that mud residual in pipeline is impacted and enters sheet frame vacuum filter, and the pressure of gas can accelerate sludge dehydration.After completing dehydration, this passage is still current, utilizes gas purifier, realizes dry deslagging.
