Description

A diaphragm plate and frame filter press

Technical Field

The utility model relates to the technical field of plate-frame filter presses, in particular to a diaphragm plate-frame filter press.

Background Art

Plate and frame filter press is the first machine used in chemical dehydration. Although plate and frame filter press is generally intermittent operation, the capital equipment investment is large, and the filtering capacity is also low, it is still widely used in some small sewage treatment plants because of its advantages such as large filtering driving force, high solid content of filter cake, clear filtrate, high solid recovery rate, and low consumption of conditioning drugs.

The plate and frame filter press has the following deficiencies during operation:

Firstly, according to the existing plate and frame filter press, after the filter cake is squeezed once, there is still a lot of water inside it. The high water content of the filter cake will increase the difficulty of the filter cake falling off, making it inconvenient to transport.

In addition, after the filter cake is squeezed, workers are usually required to manually remove the filter cake from the plate and frame filter press, which is cumbersome and increases labor costs.

Utility Model Content

In view of the deficiencies of the prior art, the utility model provides a diaphragm plate and frame filter press, which overcomes the deficiencies of the prior art and effectively solves the problem that the filter cake has a high water content and that cleaning the filter cake increases labor costs.

In order to achieve the above purpose, the utility model adopts the following technical solutions:

A diaphragm plate-frame filter press comprises a casing, the inner wall of which is welded with symmetrically distributed connecting plates, and filter plates are arranged between two connecting plates at equal distances, the inner walls of both sides of the filter plates are provided with membrane plates, and an expansion chamber is arranged inside the filter plates between the two membrane plates, a high-pressure expansion tube is connected to the bottom of the outer wall of one side of the filter plate, and a high-pressure tube is connected to the outer wall of one end of the high-pressure expansion tube;

Brackets are welded to the outer walls on both sides of the filter plate, and the outer wall at the bottom of one of the connecting plates is fixedly connected to an electric guide rail by bolts, and an air clamp is installed on the electric guide rail slider.

Preferably, a mud and water ring is opened at the center of the outer wall of one side of the filter plate, and a mud and water pipe is installed on the inner wall of one side of the casing, and a baffle is welded to the outer wall of one end of the mud and water pipe.

Preferably, a hydraulic push rod is installed on the inner wall of the other side of the casing, and the piston rod of the hydraulic push rod is connected to a hydraulic plate.

Preferably, a flushing pipe is connected to the top of the outer wall of one side of the filter plate, and a washing pipe is installed on the outer wall of one end of the flushing pipe.

Preferably, a sewage pipe is installed at the bottom of the outer wall on the other side of the filter plate, and a sewage pool is installed on the inner wall of the bottom of the casing at the bottom of the sewage pipe.

Preferably, a mud discharge bin is welded to the outer wall of the bottom of the casing.

Preferably, a PLC controller is installed on an outer wall of one side of the casing.

The beneficial effects of the utility model are:

1. The diaphragm plate and frame filter press of this design has an expansion chamber inside the filter plate. When high-pressure medium is introduced into the high-pressure pipe, the high-pressure medium can enter the expansion chamber along the high-pressure expansion pipe, and the membrane plate is squeezed, which can further reduce the moisture content of the filter cake, reduce the difficulty of the filter cake falling off, and facilitate transportation;

2. In the diaphragm plate and frame filter press of this design, after the filter cake is extruded, the air clamp is driven to move by the electric guide rail. The air clamp can clamp the brackets on the corresponding filter plates in sequence, thereby completing the separation of all filter plates, realizing the automatic detachment of the filter cake and saving manpower.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

In this embodiment, an expansion bin 5 is provided inside the filter plate 3. When a high-pressure medium is introduced into the high-pressure pipe 7, the high-pressure medium can enter the expansion bin 5 along the high-pressure expansion pipe 6, and the membrane plate 4 is squeezed, which can further reduce the moisture content of the filter cake, reduce the difficulty of the filter cake falling off, and facilitate transportation.
