[0002] In wastewater treatment filtration, regardless of the type of filter cloth, it needs to be cleaned after a period of use to maintain its performance, and filter press cloths are no exception. Horizontal belt filter equipment is usually equipped with automatic cleaning devices that can easily remove residues from the surface of the filter cloth; however, equipment like plate and frame filter presses does not have a built-in cleaning function, so their filter cloths usually need to be disassembled periodically for manual cleaning. Manual cleaning is cumbersome, requires machine shutdown for disassembly, and is a laborious and inefficient process. Therefore, we propose an online impurity removal device for plate and frame filter press cloths used in wastewater treatment. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: an online impurity removal device for filter cloth of a plate and frame filter press for sewage treatment, including two sliding seats 1 set on the drive mechanism on both sides of the filter press. The two sliding seats 1 move along the length direction of the filter press under the drive mechanism. The filter press has a drive mechanism on both sides for moving the filter frame to separate the filter cake. The sliding seat 1 of this application is set on the drive mechanism, and no additional drive mechanism is required. The sliding seat 1 can also move synchronously with the device for moving the filter frame.

[0019] A column 2 is fixedly mounted on the upper surface of the sliding base 1. A groove 3 is formed on one side of the two columns 2 facing each other. A slider is slidably mounted in the groove 3. A dust removal cover 5 is fixedly mounted between the two sliders. The dust removal cover 5 can move up and down along the groove 3 in the height direction of the column 2, following the slider. The opening of the dust removal cover 5 is in the horizontal direction, and a suction pipe 6 is provided on the side of the dust removal cover 5 away from the opening. A converging part is provided on the side of the dust removal cover 5 away from the opening. The top view cross-section of the converging part is trapezoidal, and the suction pipe 6 is located in the converging part. At its narrowest point, the end of the suction pipe 6 is connected to the dust collection box 7. The side surface of the dust collection box 7 is provided with a door 9, and the upper surface of the dust collection box 7 is equipped with a dust removal fan 10. The impurity removal hood 5 moves from bottom to top or from top to bottom via a slider. The dust removal fan 10 uses the suction pipe 6 to adsorb and collect the residual impurities, dirt, dust and other contaminants on the filter cloth into the dust collection box 7. This can realize online impurity removal of the filter cloth of the plate and frame filter press without stopping the machine for disassembly, simplifying the steps of cleaning the filter cloth, improving work efficiency and reducing the workload of the staff.

[0020] Optionally, two sets of impurity removal devices can be provided. The opening directions of the impurity removal hoods 5 of the two sets of impurity removal devices are opposite, and they respectively remove impurities from the filter cloths on the two filter frames on both sides.

[0021] In the preferred technical solution, a drive motor 4 is fixedly installed on the upper surface of the column 2. The output shaft of the drive motor 4 passes through the slide groove 3 and is connected to the drive screw through a coupling. The drive screw is rotatably installed in the slide groove 3 and is threadedly connected to the screw hole opened on the upper surface of the slider. The drive motor 4 drives the two drive screws to rotate, thereby driving the two slider machine impurity removal covers 5 to move up and down. The operation is convenient and the control is simple.

[0022] In a preferred embodiment, wheel frames are installed at the four corners of the lower surface of the dust collection box 7, and universal wheels 8 are provided on the wheel frames. A connecting frame 11 is provided between the side surface of the dust collection box 7 and the lower surface of one of the sliding seats 1. When the sliding seat 1 moves under the drive of the drive mechanism, the dust collection box 7 moves synchronously through its universal wheels 8 via the connecting frame 11, which facilitates dust collection and impurity removal from the filter cloth.

[0023] The internal structure of the dust collection box 7 is similar to that of existing canister vacuum cleaners, and will not be described in detail here.

[0024] In a preferred embodiment, a cleaning brush 12 is rotatably mounted on the inner surface of the cleaning hood 5. The cleaning brush 12 includes a rotating column and bristles evenly distributed on the outer circumferential surface of the rotating column. One end of the rotating column is inserted into the interior of one of the sliders and connected to the output shaft of a stepper motor installed inside it via a coupling. The stepper motor drives the rotating column to rotate, and the cleaning brush 12 can perform rolling brushing on the surface of the filter cloth, thereby improving the cleaning efficiency of the cleaning hood 5 and thus improving the cleaning effect on the filter cloth.

[0025] An optional technical solution involves mounting a vibration mechanism 13 on the upper surface of the dust removal hood 5. The vibration mechanism 13 includes a housing fixed to the upper surface of the dust removal hood 5. A servo motor 15 is mounted at one end of the upper surface of the housing. The servo motor 15, stepper motor, drive motor 4, and dust removal fan 10 are all electrically connected to an externally installed control switch. The output shaft of the servo motor 15 passes through the housing and connects to a driving bevel gear. A rotating shaft 17 is rotatably mounted inside the housing. A driven bevel gear, meshing with the driving bevel gear, is fixedly mounted at the end of the rotating shaft 17. A number of cams 18 are evenly arranged along their length on the outer peripheral surface. A number of through grooves are evenly opened on the side surface of the housing near the opening of the impurity removal hood 5. Vibration heads 14 corresponding to the cams 18 are slidably arranged in the through grooves. When the rotating shaft 17 rotates, the cams 18 push the vibration heads 14 to move back and forth, thereby achieving the effect of vibrating the surface of the filter cloth. This makes it easier for residual impurities, dirt and dust attached to the surface to be removed and then removed by the impurity removal hood 5, further improving the impurity removal and cleaning effect of the filter cloth and ensuring its filtration performance during subsequent use.

[0026] The servo motor 15, stepper motor, drive motor 4, and dust removal fan 10 used in this application are all commonly used electronic components in the prior art. Their specific structures, working principles, and circuit connections are all well-known technologies and will not be described in detail here.

[0027] Alternatively, the two adjacent cams 18 have opposite convex directions. When the rotating shaft 17 drives the cams 18 to rotate, the adjacent vibrating heads 14 move back and forth with inconsistent amplitudes, which can increase the vibration amplitude of the filter cloth and further improve the impurity removal effect.

[0028] Furthermore, a sliding block 19 is fixedly provided between adjacent vibrating heads 14. The sliding block 19 is located inside the housing and in a relatively inward position to avoid affecting the movement range of the vibrating head 14. A return spring 20 is provided between the side of the sliding block 19 away from the rotating shaft 17 and the inner surface of the housing. When the vibrating head 14 moves forward, it causes the sliding block 19 to move along with it, pressing the return spring 20. After the cam 18 rotates 180°, the sliding block 19 moves backward and resets under the elastic force of the return spring 20, causing the vibrating head 14 to reset as well, thus ensuring the stability of the filter cloth vibration.

[0029] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
