The filter press for environmental protection engineering drives the cleaning plate at the bottom of the hydraulic rod to move downward by extending the hydraulic rod, so that the cleaning brush on the surface of the cleaning plate cleans the filter screen on the filter press plate, and automatically cleans the filter screen.

[0004] Since the shape of the filter plate is irregular, for example, the thickness of the frame at the edge of the filter plate is greater than the thickness in the middle part, it is difficult for the cleaning brush to maintain complete fit with the surface of the filter plate when the cleaning plate in the filter press cleaning mechanism of the filter press used in the environmental protection project moves under the drive of the hydraulic rod. During the cleaning process, the cleaning brush cannot fully contact the filter screen on the filter plate, resulting in a small amount of debris remaining on the filter screen. In addition, the cleaning brush is easily deformed after being squeezed against the edge of the filter plate, resulting in a decrease in the cleaning ability of the filter press cleaning mechanism. Therefore, the reliability of the existing filter press cleaning mechanism is poor. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figures 1 to 4 As shown, an embodiment of the utility model proposes an automatic cleaning device for filter plates of a filter press, which is installed on the filter press and is used to clean the surface of the filter plates on the filter press to remove filter residues and other debris remaining on the surface of the filter plates after filtration.

[0024] Please refer to Figure 1 and Figure 2 The automatic cleaning device for filter plates of the filter press comprises a frame 1 fixedly connected to the filter press, a lifting frame 2 and a first driving assembly 3 are arranged on the frame 1, the lifting frame 2 can be lifted and lowered in the vertical direction on the frame 1, the first driving assembly 3 is transmission-connected with the lifting frame 2 and drives the lifting frame 2 to move on the frame 1, the lifting frame 2 is provided with two movable frames 4 which can be moved in the horizontal direction respectively, the two movable frames 4 are respectively arranged near the opposite sides of the lifting frame 2, the lifting frame 2 is also provided with a second driving assembly 5, the second driving assembly 5 is transmission-connected with the two movable frames 4 respectively, and the second driving assembly 5 drives the two movable frames 4 to move near each other Close or far away, the sides of the movable frames 4 that are close to each other are movably connected with the first cleaning plates 6, and the sides of the two first cleaning plates 6 that are close to each other are movably connected with the second cleaning plates 7, and the sides of the first cleaning plates 6 that are close to each other are also provided with first cleaning brushes 61, and the first cleaning brushes 61 are respectively arranged close to the opposite ends of the second cleaning plates 7, and the sides of the second cleaning plates 7 that are close to each other are provided with second cleaning brushes 71, and when the first cleaning plates 6 and the second cleaning plates 7 are respectively in free states, the distance between the first cleaning brushes 61 on the two first cleaning plates 6 is greater than the distance between the second cleaning brushes 71 on the two second cleaning plates 7.

[0025] Specifically, the operation steps of the automatic cleaning device for filter plates of the filter press provided in the present embodiment for cleaning the filter plates are as follows: the filter press first transports the filter plates to be cleaned to the bottom of the automatic cleaning device for filter plates of the filter press and fixes them between the two movable frames 4; after the filter plates are in place, the first driving component 3 drives the lifting frame 2 to first descend and then ascend in the vertical direction; during the movement of the lifting frame 2, the movable frame 4 is driven to rise and fall in the vertical direction; and during the movement of the movable frame 4, the first cleaning brush 61 and the second cleaning brush 71 on the two movable frames 4 respectively scrub the two opposite surfaces of the filter plates; the process in which the first cleaning brush 61 and the second cleaning brush 71 contact the filter plates removes the filter residues attached to the mesh of the filter screen, thereby cleaning the filter plates; and during the movement of the lifting frame 2, the second driving component 5 drives the two movable frames 4 to move respectively on the lifting frame 2 according to the changes in the shape of the filter plate surfaces; the two movable frames 4 are adjusted by driving them to move closer to or farther away from each other. 4, so as to adjust the distance between the first cleaning plate 6 and the second cleaning plate 7 and the surface of the filter plate during the process of brushing the filter plate, ensure that the first cleaning brush 61 and the second cleaning brush 71 are fully in contact with the edge part and the middle part of the filter plate respectively, and at the same time make the first cleaning brush 61 and the second cleaning brush 71 avoid the frame part of the filter plate, avoid the first cleaning brush 61 or the second cleaning brush 71 and the edge of the filter plate squeezed against each other to cause damage to the first cleaning brush 61 or the second cleaning brush 71, and the first cleaning plate 6 is movably connected to the movable frame 4, and the second cleaning plate 7 is movably connected to the first cleaning plate 6, avoid the first cleaning brush 61 or the second cleaning brush 71 from bending and deforming after abutting against the filter plate, the lifting frame 2 rises until the first cleaning brush 61 and the second cleaning brush 71 are separated from the filter plate to complete the cleaning of the filter plate, at this time, the filter press moves the cleaned filter plate to the next station and transports the next filter plate to be cleaned to the bottom of the automatic cleaning device for filter plates of the filter press. The automatic cleaning device for filter plates of the filter press provided in this embodiment can ensure that the first cleaning brush 61 and the second cleaning brush 71 are in full contact with the surface of the filter plate, thereby improving the cleaning effect and effectively reducing the residual debris on the filter plate. The movement of the movable frame 4 prevents the first cleaning brush 61 or the second cleaning brush 71 from being deformed during the cleaning process, thereby improving the reliability of the automatic cleaning device for filter plates of the filter press and helping to extend its service life.

[0026] like Figure 1 and Figure 3As shown, the first driving assembly 3 includes a motor 31, a driving rod 32 arranged at the output end of the motor 31 and a first bevel gear 33 sleeved on the driving rod 32, the axial direction of the driving rod 32 is horizontal, the first driving assembly 3 also includes a screw rod 34 rotatably arranged on the frame 1 and a second bevel gear 35 sleeved on the screw rod 34, the axial direction of the screw rod 34 is vertical and the lifting frame 2 is provided with a threaded hole 21 matching the screw rod 34, the first bevel gear 33 is meshed with the second bevel gear 35. The motor 31 drives the driving rod 32 to rotate and transmits power to the screw rod 34 through the cooperation of the first bevel gear 33 and the second bevel gear 35, so as to drive the screw rod 34 to rotate. The lifting frame 2 is provided with a threaded hole 21 that cooperates with the screw rod 34, so that when the screw rod 34 rotates, the lifting frame 2 moves along the axial direction of the screw rod 34, thereby driving the lifting frame 2 to move in the vertical direction. The rotation direction of the driving rod 32 can be changed by the motor 31 to change the rotation direction of the screw rod 34 and adjust the moving direction of the lifting frame 2, so as to control the lifting frame 2 to move in the vertical direction.

[0027] In detail, two screw rods 34 are arranged at intervals on the frame 1 and the two screw rods 34 are respectively located on opposite sides of the lifting frame 2, and the two sides of the lifting frame 2 are respectively provided with the threaded holes 21 corresponding to the screw rods 34, and two first bevel gears 33 are arranged at intervals on the driving rod 32 and the two first bevel gears 33 are respectively meshed with the second bevel gears 35 on the two screw rods 34. Two screw rods 34 are arranged at intervals on the frame 1 and two first bevel gears 33 are arranged on the driving rod 32 and are respectively matched with the corresponding second bevel gears 35, so that when the driving rod 32 rotates, the two screw rods 34 rotate synchronously, and when the two screw rods 34 rotate, the two ends of the lifting frame 2 are lifted and lowered at the same time, which is conducive to improving the stability of the lifting frame 2 when it moves, and preventing the lifting frame 2 from tilting and causing the first cleaning brush 61 or the second cleaning brush 71 to separate from the filter plate.

[0028] like Figure 1As shown, the frame 1 is further provided with a first guide rail 11, the length direction of the first guide rail 11 is the vertical direction, and the first guide rails 11 are respectively provided on the two opposite sides of the lifting frame 2, and the first sliders 22 are respectively provided on the two sides of the lifting frame 2, and the first sliders 22 are matched with the first guide rails 11 in a one-to-one manner. The first guide rail 11 provided on the frame 1 is used to guide the lifting frame 2 to move on the frame 1, and the first slider 22 cooperates with the first guide rail 11 to reduce the friction between the lifting frame 2 and the frame 1, improve the smoothness of the lifting frame 2 when moving, and ensure the overall structural stability of the automatic cleaning device for filter plates of the filter press.

[0029] Please combine Figure 1 and Figure 3 The second driving assembly 5 includes a movable plate 51 and the movable plate 51 can move in a horizontal direction on the lifting frame 2. The moving direction of the movable plate 51 is perpendicular to the moving direction of the movable frame 4. The lifting frame 2 is provided with a first guide groove 23 and the length direction of the first guide groove 23 is consistent with the moving direction of the movable frame 4. Two second guide grooves 52 are spaced apart on the movable plate 51. The two second guide grooves 52 are respectively connected to the first guide groove 23 and the distance between the two second guide grooves 52 gradually increases along the moving direction of the movable plate 51. Guide rods 41 are respectively provided on the movable frame 4. The guide rods 41 respectively pass through the first guide grooves 23 and match with the second guide grooves 52 one by one. When the movable plate 51 moves on the lifting frame 2, the guide rod 41 is pushed to slide in the first guide groove 23 through the abutment between the second guide groove 52 and the guide rod 41, and the distance between the two second guide grooves 52 on the movable plate 51 gradually increases along the moving direction of the movable plate 51. At this time, the two guide rods 41 move away from each other in the first guide groove 23 under the push of the movable plate 51, and the distance between the two movable frames 4 increases. When the movable plate 51 moves in the opposite direction, the movable plate 51 pushes the two guide rods 41 to approach each other in the first guide groove 23. At this time, the distance between the two movable frames 4 is reduced, thereby realizing the adjustment of the distance between the two movable frames 4.

[0030] Specifically, the second driving assembly 5 also includes a cylinder 53 and a telescopic rod 54 disposed at the output end of the cylinder 53, and one end of the telescopic rod 54 away from the cylinder 53 is fixedly connected to the movable plate 51, and the cylinder 53 drives the telescopic rod 54 to extend and retract in the horizontal direction, and the telescopic direction of the telescopic rod 54 is consistent with the moving direction of the movable plate 51. The cylinder 53 drives the telescopic rod 54 to extend or retract into the cylinder 53, so as to push or pull the movable plate 51 to move on the lifting frame 2, and the moving distance of the movable plate 51 is controlled by the travel of the telescopic rod 54, so as to accurately adjust the distance between the two movable frames 4, and ensure that the first cleaning brush 61 and the second cleaning brush 71 disposed on the movable frame 4 are in full contact with the filter plate.

[0031] Please refer to Figure 3 and Figure 4 The lifting frame 2 is also provided with a second guide rail 24, the length direction of the second guide rail 24 is consistent with the moving direction of the movable frame 4, and the movable frame 4 is respectively provided with a second slider 42 that cooperates with the second guide rail 24. The second guide rail 24 is used to limit the moving direction of the movable frame 4 on the lifting frame 2. The cooperation between the second slider 42 and the second guide rail 24 can prevent the lifting frame 2 from deviating from the preset direction when moving, and keep the first cleaning brush 61 and the second cleaning brush 71 in contact with the filter plate during the movement of the movable frame 4.

[0032] like Figure 2 and Figure 4 As shown, the first cleaning plate 6 is provided with a first mounting rod 62, and the movable frame 4 is provided with a first mounting hole 43 matched with the first mounting rod 62. The first mounting rod 62 is sleeved with a first spring 63, and the opposite ends of the first spring 63 in the expansion and contraction direction are respectively in contact with the movable frame 4 and the first cleaning plate 6. When the first cleaning brush 61 contacts the filter plate, the elastic force provided by the first spring 63 causes the first cleaning plate 6 to move in the direction close to the filter plate, so that the first cleaning brush 61 keeps in contact with the filter plate, and the expansion and contraction of the first spring 63 causes the first cleaning plate 6 to float on the movable frame 4, so as to prevent the first cleaning brush 61 from being squeezed and deformed when the movable frame 4 is too close to the filter plate, thereby ensuring that the first cleaning brush 61 can effectively clean the filter plate while preventing the first cleaning brush 61 from being damaged.

[0033] In detail, the second cleaning plate 7 is provided with a second mounting rod 72, and the first cleaning plate 6 is provided with a second mounting hole 64 matched with the second mounting rod 72. The second mounting rod 72 is sleeved with a second spring 73, and the opposite ends of the second spring 73 in the extension direction are respectively in contact with the first cleaning plate 6 and the second cleaning plate 7. The elastic force provided by the second spring 73 causes the second cleaning plate 7 to move away from the first cleaning plate 6 and approach the filter plate, so that the second cleaning brush 71 is kept in contact with the filter plate during the cleaning process, and the second cleaning plate 7 is supported by the second spring 73 so that the second cleaning plate 7 can move relative to the first cleaning plate 6. When the filter plate squeezes the second cleaning brush 71, the second cleaning brush 71 can be prevented from being deformed by the movement of the second cleaning plate 7 for buffering, which is conducive to extending the service life of the second cleaning brush 71.

[0034] like Figure 4 As shown, each of the first cleaning plates 6 is provided with a water spray assembly 8, which includes a mounting plate 81 and a plurality of spray heads 82 spaced apart on the mounting plate 81, and the spray direction of the spray heads 82 is toward between the two first cleaning plates 6. The water spray assembly 8 is connected to an external water source so that water can be sprayed out of the spray heads 82, and the water sprayed from the spray heads 82 is toward the filter plate located between the two first cleaning plates 6, so as to wash the filter plate and remove the debris attached to the filter plate, which is beneficial to further improve the cleaning ability of the automatic cleaning device for the filter plate of the filter press.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
