Description

Technical Field

[0001] This utility model relates to the field of chamber filter press technology, and in particular to the cleaning structure of the feed channel of a chamber filter press. Background Technology

[0002] Chamber filter presses are widely used in various solid-liquid separation processes across industries due to their simple and practical structure. Currently, chamber filter presses are also the most widely used type of filter press.

[0003] After filtration, a chamber filter press always leaves some slurry residue in the common feed channel within the plates. If left untreated, this residue will recontaminate the already dried filter cake when the press is unloaded after each operation. The traditional method involves using cleaning water or compressed air introduced into the filter chamber from the movable platen base to wash away the residual slurry before blowing it out. This ensures that the filter cake is not contaminated again by the residual slurry flowing out of the channel during unloading. However, the movable platen base itself is a structure that moves along the main beam. Therefore, the current method for connecting the pipeline often involves connecting a pressure hose. One end of this hose is fixed to the inlet of the cleaning channel of the movable platen base, and the other end is fixed to another fixed position on the machine body. The length of the hose needs to account for the space required for the movable platen base's movement. Then, a fixed pipe is used to connect it. While this solves the problem, it requires a separate pipeline, adding complexity to the site layout. Furthermore, the pressure hose is prone to aging and damage after long-term operation, requiring frequent maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a cleaning structure for the feed channel of a chamber filter press, which solves the problems of complex pipeline layout and frequent maintenance of existing cleaning structures.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] The cleaning structure of the feed channel of the chamber filter press includes a fixed base, a filter plate, and a movable pressing base. The fixed base and the filter plate are provided with a feed channel in the middle and functional channels at the four corners of the fixed base and the filter plate. A guide component connecting the feed channel and a functional channel is embedded in the movable pressing base. A check valve is provided at one end of the guide component that connects to the feed channel.

[0007] Furthermore, the guide component is a U-shaped guide tube, and a check valve is provided at one end of the U-shaped guide tube that connects to the feed channel.

[0008] Furthermore, an installation groove is provided on the side of the movable pressing machine base facing the filter plate, and positioning grooves adapted to the U-shaped guide tube are provided on the side wall and bottom wall of the installation groove, and a fixing block is inserted into the installation groove.

[0009] Furthermore, a first tee pipe is connected to a functional channel of the fixed base, and a second tee pipe is connected to the feed channel of the fixed base. The first tee pipe is connected to a compressed air pipe and a cleaning water pipe, and the second tee pipe is connected to a feed pipe and a discharge pipe. Control valves are provided on the compressed air pipe, the cleaning water pipe, the feed pipe, and the discharge pipe.

[0010] This utility model has the following advantages: By using one of the multiple functional channels in the existing filter plate, the compressed air or cleaning water required for cleaning is connected to the fixed base.

[0021] refer to Figure 1-3 As shown, one embodiment of this utility model is as follows:

[0022] The cleaning structure of the feed channel of the chamber filter press includes a fixed base 1, a filter plate 2, and a movable pressing base 3. The fixed base 1 and the filter plate 2 are provided with a feed channel 4 in the middle. The fixed base 1 and the filter plate 4 are provided with functional channels 5 at the four corners. The movable pressing base 3 is embedded with a guide component that connects the feed channel 4 and a functional channel 5. One end of the guide component that connects to the feed channel 4 is provided with a check valve 6.

[0023] Specifically, a functional channel 5 of the fixed base 1 is connected to a first three-way pipe 7, and a feeding channel 4 of the fixed base 7 is connected to a second three-way pipe 8. The first three-way pipe 7 is connected to a compressed air pipe and a cleaning water pipe, and the second three-way pipe 8 is connected to a feeding pipe and a slurry discharge pipe. Control valves are provided on the compressed air pipe, the cleaning water pipe, the feeding pipe, and the slurry discharge pipe.

[0024] In the operation of a chamber filter press, washing and air blowing can be achieved using the two functional channels at the bottom of the filter plate, while the upper functional channels are often left in standby. Therefore, this application utilizes one of the multiple functional channels in an existing filter plate, connecting the required compressed air or cleaning water to the fixed base 1 via a first three-way pipe 7. Using the existing functional channel, a guide element embedded in the movable pressing base 3 connects the functional channel 5 and the feed channel 4, directly introducing the required cleaning water or compressed air into the common feed channel 4 within the filter chamber for cleaning. This method is simple to install, requires fewer materials, and facilitates installation and maintenance. It eliminates the need for additional pressure hoses and other components, avoiding the aging phenomenon that occurs with existing pressure-resistant hoses after long-term operation, thus providing a superior solution for the overall technology.

[0025] The compressed air pipe and the cleaning water pipe are opened or closed via control valves on their respective fittings. Specifically, when cleaning with cleaning water, the control valve on the compressed air pipe is closed and the control valve on the cleaning water pipe is open; when cleaning with compressed air, the control valve on the compressed air pipe is open and the control valve on the cleaning water pipe is closed.

[0026] The feed pipe and discharge pipe are opened or closed by control valves on their respective fittings. Specifically, during feeding, the control valve on the feed pipe is open and the control valve on the discharge pipe is closed; during cleaning, the control valve on the feed pipe is closed and the control valve on the discharge pipe is open.

[0027] In this embodiment, the guide component is specifically selected as a U-shaped guide pipe 9, and a check valve 6 is provided at one end of the U-shaped guide pipe 9 that connects to the feed channel 4.

[0028] The U-shaped guide pipe 9 has a simple structure and is easy to implement. Due to its pipe structure, there is a straight section after the water flow turns back, which can effectively ensure the cleaning effect of residual slurry.

[0029] As shown in the figure, the inlet end of the U-shaped guide pipe 9 extends into the feed channel on the filter plate 2 fixed on the movable clamping seat 3. Since the filter plate 2 fixed on the movable clamping seat 3 is the tail plate, there is no need to set the feed channel 4. In order to facilitate the setting of the check valve and subsequent maintenance, the outlet end of the U-shaped guide pipe 9 can pass through the tail plate and be equipped with a check valve 6.

[0030] In practical implementation, an installation groove 10 can be provided on the side of the movable clamping machine 3 facing the filter plate. The side wall and bottom wall of the installation groove 10 are provided with positioning grooves 11 adapted to the U-shaped guide tube. The U-shaped guide tube 9 is inserted into the positioning groove 11 in the installation groove 10, and then the fixing block 12 is inserted to fix the position before installing the tail plate and check valve. The positioning groove 11 is a semi-circular slot structure adapted to the U-shaped guide tube, and the corresponding fixing block 12 also has a semi-circular slot.

[0031] Understandably, the guide component can also be a guide groove structure directly opened on the plate. Specifically, a through hole is opened on the tail plate to connect to the feed channel, and a check valve is directly set on the through hole with its outlet facing the feed channel. The guide groove can be opened on the front of the movable clamping seat or the back of the tail plate, and it is necessary to ensure that the guide groove connects to the functional channel 5 and the through hole.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
