[0002] The plate and frame filter press was the first machine used in chemical dehydration. Although the plate and frame filter press is generally operated intermittently, the investment in infrastructure equipment is large, and the filtration capacity is relatively low, it has the advantages of large filtration driving force, high solid content of filter cake, clear filtrate, high solid recovery rate, and low consumption of conditioning chemicals.

[0003] According to the disclosed plate and frame filter press (publication number: CN 219355366U) for easy replacement of filter plates, it includes a plate frame and two mounting plates, the lower surface of the mounting plate is fixedly connected to a support leg, the side of the right mounting plate is fixedly connected to a hydraulic cylinder, the telescopic end of the hydraulic cylinder is fixedly connected to a pressure plate, the side of the left mounting plate is fixedly connected to a liquid injection pipe, the front and back of the mounting plate are fixedly connected to mounting strips, the upper surface of the mounting strip is slidably connected to a concave plate, the back of the concave plate is fixedly connected to a concave seat, and the front and back of the plate frame are fixedly connected to mounting blocks.

[0004] In the above application, the cooperation between the pressure plate and the hydraulic cylinder assembly makes it difficult to clean the filter plate after work, resulting in excessive accumulation of debris on the surface of the plate frame and filter plate after long-term use. Therefore, we propose a plate and frame filter press that is easy to replace the filter plate. Utility Model Content

[0005] The utility model provides a plate-and-frame filter press with convenient filter plate replacement, which solves the problems raised in the above documents.

[0006] The technical solution of the utility model is as follows:

[0007] The utility model is a plate and frame filter press for facilitating the replacement of filter plates, comprising a support frame, a support column being fixedly connected to the bottom of the support frame, a support shaft being fixedly connected to the side of the support frame, and an extrusion mechanism being arranged inside the support frame;

[0008] The extrusion mechanism includes a bidirectional motor, the output shaft of the bidirectional motor is fixedly connected to a threaded rod, the circumferential surface of the threaded rod is threadedly connected to a threaded sleeve, the side of the threaded sleeve is rotatably connected to a connecting plate, the end of the connecting plate away from the side of the threaded sleeve is rotatably connected to a movable plate, a slide rail is provided on the top of the support frame, a pulley is provided on the side of the movable plate, the top of the slide rail is slidably connected to a plate frame, and the side of the plate frame is threadedly connected to a filter plate.

[0009] Furthermore, an extrusion spring is fixedly connected to the side of the plate frame, and one end of the extrusion spring away from the side of the plate frame is fixedly connected to the side of the other plate frame. The function of the extrusion spring one end away from the side of the plate frame being fixedly connected to the side of the other plate frame is that when the movable plate does not push the plate frame, the elasticity of the extrusion spring makes it easy to disassemble the filter plate between the plate frames.

[0010] Furthermore, the side of the plate frame is elastically connected to the side of another plate frame through an extrusion spring, and the end of the threaded rod away from the output end of the bidirectional motor is fixedly passed through the limiting plate. The function of the end of the threaded rod away from the output end of the bidirectional motor being fixedly passed through the limiting plate is to limit the displacement distance of the threaded sleeve through the limiting plate.

[0011] Furthermore, a limiting shaft is fixedly connected to the side of the bidirectional motor, and the circumferential surface of the limiting shaft penetrates the side of the threaded sleeve and is slidingly connected to the side of the threaded sleeve. The circumferential surface of the limiting shaft penetrates the side of the threaded sleeve and is slidingly connected to the side of the threaded sleeve. The function of the limiting shaft is to prevent the threaded sleeve from rotating during the movement.

[0012] Furthermore, the side of the plate frame is located on the displacement track of the movable plate, the number of the plate frames is set to five, and the linear array is arranged along the side of the support frame. The function of the side of the plate frame being located on the displacement track of the movable plate is to ensure that the plate frame can be pushed to move during the movement of the movable plate. The number of the plate frames is set to five, and the function of the linear array along the side of the support frame is to press multiple filter plates through multiple plate frames.

[0013] Furthermore, a cleaning mechanism is provided on the side of the support frame, and the cleaning mechanism includes a connecting rod, one end of the connecting rod is fixedly connected to the side of the movable plate, and the end of the connecting rod away from the side of the movable plate is fixedly connected to the push plate, and the side of the support frame is fixedly connected to the cleaning box, the interior of the cleaning box is slidably connected to the extrusion plate, and the side of the extrusion plate is fixedly connected to the force-bearing rod, the circumferential surface of the force-bearing rod passes through the side of the cleaning box and is slidably connected to the side of the cleaning box, and the side of the cleaning box is fixedly penetrated by a conveying pipe, and the end of the conveying pipe away from the side of the cleaning box is fixedly penetrated by a conveying plate, and the side of the conveying plate is fixedly connected to a nozzle. The role of the cleaning mechanism provided on the side of the support frame is to clean the plate frame and filter plate while replacing the filter plate, so as to ensure the cleanliness and hygiene of the equipment.

[0014] Furthermore, a return spring is fixedly connected to the side of the cleaning box, and one end of the return spring away from the side of the cleaning box is fixedly connected to the circumferential surface of the force-bearing rod. The function of the return spring being fixedly connected to the circumferential surface of the force-bearing rod at one end away from the side of the cleaning box is to reset the force-bearing rod through the elasticity of the return spring when the force-bearing rod is not under force.

[0015] Furthermore, one end of the force-bearing rod is elastically connected to the side of the cleaning box through a return spring, and the side of the support column is fixedly connected to the collection box, which is used to collect cleaning liquid and debris after cleaning.

[0016] Furthermore, a water injection pipe is provided on the side of the cleaning box, and a sealing plug is slidably connected inside the water injection pipe. The function of the water injection pipe provided on the side of the cleaning box is to add cleaning liquid to the inside of the cleaning box through the water injection pipe, and the function of the sealing plug is slidably connected inside the water injection pipe to prevent the cleaning liquid from leaking through the water injection pipe when the cleaning box is working.

[0017] Furthermore, one end of the force-bearing rod is located on the displacement track of the push plate, the number of the nozzles is set to four, and the linear array is arranged along the side of the conveying plate. The function of one end of the force-bearing rod being located on the displacement track of the push plate is to ensure that the push plate presses one end of the force-bearing rod during the movement. The number of the nozzles is set to four, and the linear array is arranged along the side of the conveying plate to simultaneously clean multiple filter plates through multiple nozzles.

[0018] The working principle and beneficial effects of the utility model are as follows:

[0019] 1. The utility model cooperates with each other among the components such as the bidirectional motor, movable plate and filter plate of the extrusion mechanism. When a clean filter plate is needed, it is placed inside the plate frame, and then the bidirectional motor is started to press the movable plate against the plate frame, and the filter plate is pressed through multiple plate frames. When the plate frame finishes squeezing the filter plate, the threaded sleeve is reset by clockwise rotation of the bidirectional motor. At this time, the plate frame is not subjected to the pressure of the movable plate, and the plate frames are separated by a certain distance by the extrusion spring for easy replacement. This design achieves the effect of squeezing the filter plate, and at the same time makes it easy to replace the filter plate after the plate frame and filter plate work is completed.

[0020] 2. The utility model cooperates with the cleaning box, nozzle and collection box of the cleaning mechanism. When the plate frame is finished working, the staff pulls out the sealing plug before adding cleaning liquid to the inside of the cleaning box through the water injection pipe. When the bidirectional motor rotates clockwise, the movable plate is reset so that the push plate pushes the force rod. The cleaning liquid inside the cleaning box enters the inside of the conveying plate through the delivery pipe and is then sprayed out through the nozzle. When the filter plate is replaced, the plate frame and filter plate can be cleaned at the same time. The used cleaning liquid and cleaned debris fall into the collection box. When the extrusion mechanism works next time, the force rod is not forced and is reset by the reset spring. At this time, the nozzle stops feeding the cleaning liquid. This design achieves the effect of cleaning the plate frame and filter plate after use, ensuring the cleanliness and hygiene of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The extrusion mechanism 4 includes a bidirectional motor 41, the output shaft of the bidirectional motor 41 is fixedly connected to a threaded rod 42, the circumferential surface of the threaded rod 42 is threadedly connected to a threaded sleeve 43, the side of the threaded sleeve 43 is rotatably connected to a connecting plate 44, and the end of the connecting plate 44 away from the side of the threaded sleeve 43 is rotatably connected to a movable plate 45, a slide rail 46 is provided at the top of the support frame 1, a pulley 47 is provided on the side of the movable plate 45, the top of the slide rail 46 is slidably connected to a plate frame 48, and the side of the plate frame 48 is threadedly connected to a filter plate 49.

[0032] An extrusion spring 410 is fixedly connected to the side of the plate frame 48, and one end of the extrusion spring 410 away from the side of the plate frame 48 is fixedly connected to the side of the other plate frame 48. The function of the extrusion spring 410 being fixedly connected to the side of the other plate frame 48 at one end away from the side of the plate frame 48 is that when the moving plate 45 does not push the plate frame 48, the elasticity of the extrusion spring 410 makes it easy to disassemble the filter plate 49 between the plate frames 48.

[0033] The side of the plate frame 48 is elastically connected to the side of another plate frame 48 through an extrusion spring 410. The end of the threaded rod 42 away from the output end of the bidirectional motor 41 is fixedly passed through the limiting plate 411. The function of the end of the threaded rod 42 away from the output end of the bidirectional motor 41 is to limit the displacement distance of the threaded sleeve 43 through the limiting plate 411.

[0034] A limiting shaft 412 is fixedly connected to the side of the bidirectional motor 41. The circumferential surface of the limiting shaft 412 penetrates the side of the threaded sleeve 43 and is slidingly connected to the side of the threaded sleeve 43. The circumferential surface of the limiting shaft 412 penetrates the side of the threaded sleeve 43 and is slidingly connected to the side of the threaded sleeve 43. The function of the limiting shaft 412 is to prevent the threaded sleeve 43 from rotating during the movement.

[0035] The side of the plate frame 48 is located on the displacement track of the movable plate 45. The number of the plate frames 48 is set to five, and they are linearly arrayed along the side of the support frame 1.

[0036] The screw sleeve 43 is moved in the direction of the bidirectional motor 41 to drive the connecting plate 44 to move. At this time, the movable plate 45 is subjected to the thrust and moves from right to left on the slide rail 46 through the pulley 47. During the movement of the movable plate 45 from right to left, the plate frame 48 is squeezed by the thrust and the plate frame 48 is squeezed between the plate frames 48. When the plate frame 48 completes the squeezing of the filter plates 49, the screw sleeve 43 is reset by the clockwise rotation of the bidirectional motor 41. At this time, the plate frame 48 is not subjected to the pressure of the movable plate 45. The plate frames 48 are separated by the squeezing spring 410, which makes it convenient for the staff to replace the filter plate 49.

The function of the cleaning mechanism 5 provided on the side of the support frame 1 is to clean the plate frame 48 and the filter plate 49 while replacing the filter plate 49, so as to ensure the cleanliness and hygiene of the equipment.

[0039] A return spring 59 is fixedly connected to the side of the cleaning box 53, and the end of the return spring 59 away from the side of the cleaning box 53 is fixedly connected to the circumferential surface of the force-bearing rod 55. The function of the return spring 59 being fixedly connected to the circumferential surface of the force-bearing rod 55 at one end away from the side of the cleaning box 53 is to reset the force-bearing rod 55 through the elasticity of the return spring 59 when the force-bearing rod 55 is not under force.

[0040] One end of the force-bearing rod 55 is elastically connected to the side of the cleaning box 53 through a return spring 59.

The number of nozzles 58 is set to four, and they are linearly arrayed along the side of the conveying plate 57 to simultaneously clean multiple filter plates 49 through multiple nozzles 58.

[0043] When the filter plate 49 is replaced, the cleaning liquid in the cleaning box 53 can be cleaned by the cleaning agent 512 and the cleaning agent 512 is added to the cleaning box 53 through the water injection pipe 511. When the two-way motor 41 rotates clockwise, the movable plate 45 is reset and the push plate 52 is driven by the connecting rod 51 to move from left to right.
