DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a filter press with anti-clogging function includes a feed pipe 1, a crushing part 2 is fixedly connected to the bottom end of the feed pipe 1, a connecting pipe 3 is fixedly connected to the bottom end of the crushing part 2, a processing box 4 is fixedly installed at one end of the connecting pipe 3 away from the crushing part 2, a drain pipe 5 is fixedly installed at the bottom end of the processing box 4, a filter screen 6 is arranged inside the processing box 4, and a scraping assembly is arranged at the top end of the filter screen 6;

[0024] Among them, the scraping assembly includes a scraper 21 arranged at the top of the filter 6, a mounting plate 7 is fixedly installed on the top of the scraper 21, an auxiliary scraping assembly is arranged inside the mounting plate 7, a connecting rod 8 is fixedly installed on the top of the mounting plate 7, the connecting rod 8 is slidably installed inside the processing box 4, a reciprocating screw 9 is embedded in the connecting rod 8, and a motor 10 is installed at one end of the reciprocating screw 9.

[0025] Existing: CN218709882U discloses a filter press with anti-clogging feed. This patent discloses the feed pipe, crushing part, feed pipe and mesh frame proposed in the present application document. The feed pipe 1, crushing part 2, connecting pipe 3, processing box 4, drain pipe 5 and filter screen 6 in the present application document all adopt the same technical means in the prior art, and this technical means will not be repeated here one by one.

[0026] By setting the scraping assembly, when the device is used, the mixed liquid is first discharged into the crushing part 2 through the feed pipe 1, and the mixed liquid is crushed by the crushing part 2 and then discharged from the connecting pipe 3 to the processing box 4. The crushed mixed liquid is filtered through the filter screen 6 and then discharged from the drain pipe 5 to the device for pressure filtration;

[0027] At the same time, the motor 10 can be started by controlling the PLC. The start of the motor 10 drives the rotation of the reciprocating screw 9. The rotation of the reciprocating screw 9 drives the connecting rod 8 to move back and forth. The movement of the connecting rod 8 drives the movement of the mounting plate 7. The movement of the mounting plate 7 drives the movement of the scraper 21. The scraper 21 reciprocates to scrape the impurities or sludge on the top of the filter screen 6 for easy discharge through the filter screen 6. This avoids the situation in which after the original equipment uses the extrusion plate to extrude the sludge, when the extrusion plate moves upward and resets, there will be mixed liquid passing through the top, causing part of the mixed liquid and impurities to fall above the extrusion plate and be difficult to discharge, thereby affecting the stability of the device during use, thereby ensuring the stability and reliability of the device when performing anti-blocking operations on the filter press.

[0028] like Figures 1 to 4 As shown, both sides of the top of the mounting plate 7 are configured as inclined surfaces.

[0029] During drainage, the mixed liquid can be diverted to prevent the mixed liquid from accumulating on the top of the mounting plate 7 .

[0030] like Figures 1 to 4As shown, the auxiliary scraping assembly includes a second connecting plate 16 arranged inside the mounting plate 7. The second connecting plate 16 is slidably mounted inside the mounting plate 7, and bristles 20 are evenly mounted on the bottom end of the second connecting plate 16.

[0031] By setting up the auxiliary scraping component, when the mounting plate 7 moves, the movement of the mounting plate 7 drives the movement of the second connecting plate 16, and the movement of the second connecting plate 16 drives the movement of the bristles 20, so that the bristles 20 move on the top of the filter 6, which can not only clean the surface of the filter 6, but also assist the scraping component to scrape off impurities and sludge on the top of the filter 6, further ensuring the stability of the device during operation.

[0032] like Figures 1 to 4 As shown, one end of the second connecting plate 16 is fixedly connected to the second moving rod 19 , and one end of the second moving rod 19 is provided with a moving plate 14 , and the moving plate 14 is fixedly installed inside the processing box 4 .

[0033] When the mounting plate 7 drives the second connecting plate 16 to move, the second connecting plate 16 drives the second moving rod 19 to slide on one side of the moving plate 14. The side wall of the moving plate 14 is arranged with a concave-convex configuration, and the second moving rod 19 can be squeezed by the protrusion of the moving plate 14 to move to the side away from the moving plate 14, so that the bristles 20 move on the surface of the filter 6 to improve the cleaning effect.

[0034] like Figures 1 to 4 As shown, a slider 17 is fixedly connected to the top of the second connecting plate 16 . The slider 17 is slidably mounted inside the mounting plate 7 . A second spring 18 is disposed on one side of the slider 17 .

[0035] like Figures 1 to 4 As shown, a first connecting plate 11 is slidably installed inside the mounting plate 7, a knocking rod 13 is fixedly connected to the bottom end of the first connecting plate 11, a first moving rod 15 is fixedly installed at one end of the first connecting plate 11, and the first moving rod 15 is arranged at the top end of the moving plate 14.

[0036] When the second connecting plate 16 moves to the side away from the movable plate 14, the movement of the second connecting plate 16 drives the movement of the slider 17. When the slider 17 moves, the second spring 18 is deformed to store elastic potential energy. When the second movable rod 19 moves to the recessed part of the side wall of the movable plate 14, the elastic potential energy is released by the second spring 18 to drive the second connecting plate 16 to move, thereby causing the bristles 20 to move back and forth.

[0037] like Figures 1 to 4 As shown, the first connecting plate 11 is slidably mounted inside the mounting plate 7 , and a first spring 12 is mounted on the top end of the first connecting plate 11 .

[0038] The top of the movable plate 14 is concave and convex. When the mounting plate 7 drives the first connecting plate 11 to move, the movement of the first connecting plate 11 drives the movement of the first moving rod 15, so that the first moving rod 15 slides on the top of the movable plate 14, thereby driving the first connecting plate 11 and the knocking rod 13 to move. When the first moving rod 15 slides to the top of the movable plate 14, the first connecting plate 11 squeezes the first spring 12 so that the first spring 12 stores elastic potential energy. When the first connecting plate 11 slides from the top of the movable plate 14 to the concave part, the elastic potential energy is released by the first spring 12 to drive the first connecting plate 11 to start downward, so that the knocking rod 13 moves up and down to knock the filter screen 6 back and forth, thereby facilitating sludge discharge.

[0039] The utility model provides a filter press with anti-clogging function, and the specific working principle is as follows:

[0040] When the filter press is needed, the mixed liquid is first discharged into the crushing part 2 through the feed pipe 1, and the mixed liquid is crushed by the crushing part 2 and then discharged from the connecting pipe 3 to the processing box 4. The crushed mixed liquid is initially filtered through the filter screen 6 and then discharged from the drain pipe 5 to the equipment for filter pressing;

[0041] At the same time, the motor 10 can be started by PLC control, the start of the motor 10 drives the rotation of the reciprocating screw 9, the rotation of the reciprocating screw 9 drives the connecting rod 8 to move back and forth, the movement of the connecting rod 8 drives the movement of the mounting plate 7, the movement of the mounting plate 7 drives the scraper 21 to move, and the impurities or sludge on the top of the filter screen 6 are scraped for easy discharge;

[0042] At the same time, the movement of the mounting plate 7 drives the knocking rod 13 and the bristles 20 to move to clean the top of the filter screen 6, thereby assisting in the discharge of sludge and impurities;

[0043] At the same time, the first moving rod 15 and the second moving rod 19 contact and move with the moving plate 14 during the movement of the mounting plate 7, and the first connecting plate 11 and the second connecting plate 16 move back and forth through the cooperation of the first spring 12 and the second spring 18, thereby assisting the discharge of sludge impurities and preventing the filter press from being blocked.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
