[0001] This utility model relates to the field of plate and frame filter presses, and in particular to a plate and frame filter cloth cleaning device. Background Technology

[0002] Plate and frame filter presses are mainly used for solid-liquid separation in the industrial field. They use filter plates arranged to form filter chambers. Under pressure, liquid is forced through the filter cloth and discharged, while solid particles are trapped to form a filter cake, thus achieving solid-liquid separation. Currently, the filter cloth of plate and frame filter presses is generally cleaned by rinsing. However, some particles that are stuck to the filter cloth are not easily washed off, resulting in incomplete cleaning. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a plate and frame filter cloth cleaning device that uses a rolling friction method in conjunction with rinsing to ensure that the adhered filter cake is smoothly washed off, resulting in a cleaner cleaning.

[0004] The technical solution of this utility model is as follows:

[0005] A plate and frame filter cloth cleaning device, comprising:

[0006] The support frame includes columns and crossbeams. The columns include two columns, which are symmetrically arranged on the top of the plate pullers on both sides of the plate and frame filter press. The crossbeams are located at the top of the two columns.

[0007] The lifting part includes a lifting mechanism and a support plate. The lifting mechanism is mounted on a crossbeam, and the support plate is located at the bottom of the lifting mechanism. The bottom of the support plate is provided with several buckles.

[0008] The cleaning unit includes a cleaning pipe and rollers. The cleaning pipe is snapped together with a buckle, and several nozzles are provided on the bottom side of the cleaning pipe. Connecting seats are also provided on both sides of the bottom of the support plate. The rollers include two rollers, which are arranged horizontally and parallel to each other. The two ends of the rollers are respectively provided with rotating shafts that are rotatably connected to the connecting seats.

[0009] In a further technical solution, the outer surface of the roller is provided with a plurality of extrusion teeth evenly distributed axially.

[0010] In a further technical solution, a movable opening is provided at the connection between the connecting seat and the rotating shaft. A movable block and a spring are provided in the movable opening. Space is left in the movable opening for the movable block to slide horizontally. The two ends of the spring are respectively connected to the movable block and the inner wall of the movable opening near the middle of the connecting seat. A connecting hole is provided through the movable block, and a bearing for connecting the rotating shaft is provided in the connecting hole.

[0011] In a further technical solution, the nozzle is tilted downwards towards both sides of the bottom of the cleaning pipe.

[0012] In a further technical solution, the nozzle includes a first nozzle and a second nozzle alternately disposed at the bottom of the cleaning pipe, the second nozzle being disposed facing the roller, and the first nozzle being disposed at a higher angle than the second nozzle.

[0013] In a further technical solution, the support plate is provided with connecting sleeves that are slidably sleeved on the outside of the column on both sides.

[0014] In a further technical solution, the lifting mechanism is a hydraulic rod.

[0015] The beneficial effects of this utility model are:

[0016] 1. Based on the traditional rinsing of plate and frame filter cloth, this invention utilizes the movement characteristics of the existing plate and frame filter press's plate puller by adding a lifting mechanism and a roller. The plate puller can pause when it moves between two adjacent plate and frame filter cloths, and the support frame is placed between the two filter cloths. The water source is connected to the cleaning pipe, and the lifting mechanism raises and lowers the cleaning pipe and the roller to complete the rinsing of different positions on the opposite surfaces of the two plate and frame filter cloths, resulting in a more comprehensive rinsing area. In particular, the roller can squeeze the stubborn filter cake that adheres. When squeezed, the filter cake deforms and breaks, making it easier to be rinsed off, ensuring that the adhered filter cake is washed off smoothly and cleaned more thoroughly.

[0017] 2. The roller is equipped with extrusion teeth, which makes the roller surface uneven, leaving gaps for the filter cake to deform. When the filter cake is squeezed, the force is uneven, which is conducive to the deformation of the filter cake.

[0018] 3. The first nozzle can rinse the plate and frame filter cloth above the drum, and the second nozzle can rinse the drum itself to avoid excessive filter cake adhering to the drum, which would affect subsequent cleaning.

[0019] 4. The two sides of the support plate are slidably connected to the columns through connecting sleeves, making the lifting and lowering of the support plate more stable. Attached Figure Description

[0025] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0026] Example:

[0027] like Figures 1-2 As shown, a plate and frame filter cloth cleaning device includes a support frame 10, a cleaning section, and a lifting section. The support frame 10 includes columns 11 and crossbeams 12. Two columns 11 are symmetrically arranged on the tops of the plate pullers 21 on both sides of the plate and frame filter press 20. The crossbeams 12 are located at the tops of the two columns 11. The lifting section includes a lifting mechanism and a support plate 32. The lifting mechanism can be a hydraulic rod 31, located on the crossbeams 12. The support plate 32 is located at the bottom of the hydraulic rod 31, and the hydraulic rod 31 is connected to the middle of the support plate 32. The bottom of the support plate 32 is provided with several... The cleaning tube 41 is snapped into a buckle 33; the cleaning part includes a cleaning tube 41 and a roller 44. The cleaning tube 41 is snapped into a buckle 33. Several downward-sloping nozzles are provided on both sides of the bottom of the cleaning tube 41 for spraying water toward the filter cloth on both sides; the bottom sides of the support plate 32 are also provided with connecting seats 50 respectively. The connecting seats 50 are inverted "T" shape. There are two rollers 44. The two rollers 44 are horizontal and parallel to each other. The two ends of the rollers 44 are respectively provided with rotating shafts 45 that are rotatably connected to the connecting seats 50. The rotating shafts 45 are located on both sides of the bottom of the connecting seats 50.

[0028] The working principle of the above technical solution is as follows:

[0029] When cleaning the filter cloth, the plate puller 21 pulls apart the adjacent filter plates 22 one by one. During this process, the plate puller 21 can pause when it moves between two adjacent plate and frame filter cloths. The support frame 10 is placed between the two plate and frame filter cloths, the water source is connected to the cleaning pipe 41, and the hydraulic rod 31 extends to gradually lower the support plate 32. During this process, the roller 44 rolls and squeezes the filter cloths on both sides. The cleaning pipe 41 completes the rinsing of different positions on the opposite surfaces of the two plate and frame filter cloths. The roller 44 can squeeze the stubborn filter cake that is stuck together. When squeezed, the filter cake is deformed and broken. After squeezing, the nozzle rinses it, making it easier to be rinsed off. After rinsing, the hydraulic rod 31 lifts the support plate 32 to reset, and the plate puller 21 drives the device to the next location, repeating the above steps for cleaning.

[0030] In another embodiment, such as Figure 3 As shown, the outer surface of the roller 44 is uniformly provided with several extrusion teeth 46 along the axial direction.

[0031] The roller 44 is provided with extrusion teeth 46, which makes the surface of the roller 44 uneven, leaving gaps for the deformation of the filter cake. When the filter cake is extruded, the force is uneven, which is conducive to the deformation of the filter cake.

[0032] In another embodiment, such as Figure 3 As shown, a movable opening is provided at the connection between the connecting seat 50 and the rotating shaft 45. A movable block 51 and a spring 52 are provided in the movable opening. Space is left in the movable opening for the movable block 51 to slide horizontally. When the movable block 51 is actually installed, any limiting component can be set at the movable opening to prevent the movable block 51 from disengaging from the movable opening. The two ends of the spring 52 are respectively connected to the movable block 51 and the inner wall of the movable opening near the middle of the connecting seat 50. A connecting hole is provided through the movable block 51, and a bearing for connecting the rotating shaft 45 is provided in the connecting hole.

[0033] When the roller 44 squeezes the filter cloth, the filter cloth will deform. The movable block 51 and spring 52 are provided. When the roller 44 squeezes the filter cloth, the spring 52 is compressed to ensure that the roller 44 always fits the filter cloth, while avoiding excessive squeezing of the filter cloth.

[0034] In another embodiment, such as Figure 1 As shown, the nozzle includes a first nozzle 42 and a second nozzle 43 alternately disposed at the bottom of the cleaning pipe 41. The second nozzle 43 is disposed facing the roller 44, and the first nozzle 42 is disposed at a higher angle than the second nozzle 43.

[0035] The first nozzle 42 can rinse the plate and frame filter cloth above the drum 44, and the second nozzle 43 can rinse the drum 44 to avoid excessive filter cake adhering to the drum 44, which would affect subsequent cleaning.

[0036] In another embodiment, such as Figure 1 As shown, the support plate 32 has connecting sleeves 34 that are slidably sleeved on the outside of the column 11 on both sides.

[0037] The two sides of the support plate 32 are slidably connected to the column 11 through the connecting sleeve 34, making the lifting and lowering of the support plate 32 more stable.

[0038] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
