Description

Technical Field

[0001] The utility model belongs to the field of impurity cleaning of filter presses, in particular to an automatic cleaning device for filter presses and a filter press. Background Art

[0002] The filter press uses the filter cloth installed on the filter plate as a filter medium to intercept particles in the material, and uses the permeability of the filter cloth to discharge the filtrate. It is suitable for filtering various materials. In the process of using the filter press to filter materials, some residual materials will stick to the filter cloth, affecting the filtering effect and filtering efficiency of the filter press. Therefore, it is necessary to clean the residual materials and impurities on the filter plate before it can be used again. In the prior art, there are two main ways to clean the filter plate. One is manual shoveling. Due to the heavy weight of the filter plate itself, it is difficult to pull it manually, which is inconvenient to operate and inefficient. It is limited by the operation of workers, and the quality of the shoveling operation cannot be controlled, which affects the filtering effect of the filter press; the other is through the filter press shoveling device. The existing shoveling device can only remove the silicon mud on one side of the filter plate each time, and it requires manual assistance to complete the shoveling action from the first plate to the last plate. The degree of automation is low, which affects the shoveling efficiency. Utility Model Content

[0050] The embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0051] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model proposes an automatic cleaning device for a filter press, which is used to clean a filter plate 51 of a filter press 50, and the device comprises: an independently operated first shoveling unit 10 and a second shoveling unit 20, an X-axis moving unit 30 and a control unit 60;

[0052] The first scraping unit 10 and the second scraping unit 20 are oppositely disposed on the X-axis moving unit 30 , and are both provided with at least three independent scraping blade assemblies 11 , and can be lifted and lowered along the second direction to clean the filter plate 51 .

[0053] The X-axis moving unit 30 is provided with a positioning moving support 32 and a clamping mechanism 31; the positioning moving support 32 drives the clamping mechanism 31 to reciprocate along the first direction to position, clamp and move the filter plate 51, so as to clean and gather the filter plate 51;

[0054] The control unit 60 is configured with a controller (not shown) and is communicatively connected with the first shoveling unit 10 , the second shoveling unit 20 , the positioning movable support 32 and the clamping mechanism 31 , respectively.

[0055] Specifically, Figure 2 , Figure 4 As shown, in the present application, the first shoveling unit 10 and the second shoveling unit 20 are arranged on the X-axis moving unit 30, and the two have the same structure, and are respectively used to clean the two filtering surfaces in the thickness direction of the filter plate 51, and both can operate independently; when in use, the first shoveling unit 10 and the second shoveling unit 20 can be opened at the same time to clean the two filtering surfaces of the filter plate 51 synchronously, or the first shoveling unit 10 or the second shoveling unit 20 can be opened separately according to needs to clean one filtering surface of the filter plate 51, so as to meet various cleaning needs;

[0056] In this embodiment, if Figure 1 As shown, the pressing unit 53 of the filter press 50 is located at its end, and is used to press a plurality of filter plates 51 arranged along a first direction; the pressing surface of the pressing unit 53 that is in contact with the filter plate 51 needs to be cleaned, and the other side does not need to be cleaned; similarly, the last filter plate 51 at the other end of the filter press 50 is the end plate 52, and the end plate 52 only needs to clean a filtering surface that is in contact with the previous filter plate 51; the filtering surfaces on both sides of the other plurality of filter plates 51 arranged along the first direction except the end plate 52 need to be cleaned; in addition, the first shoveling unit 10 and the second shoveling unit 20 can also be used in other working conditions, such as special working conditions where one or some filter plates 51 need to be cleaned.

[0057] like Figure 4As shown, in the present application, the first shoveling unit 10 and the second shoveling unit 20 are lifted and lowered in the second direction to drive the blade assembly 11 to operate to complete the cleaning operation of the filter plate 51, and the cleaning operation includes the shoveling operation during the descent process and the scraping operation during the ascent process; the blade assembly 11 is constructed into at least three groups, and can operate independently. The purpose of this design is to adapt to the structure of the filter plate 51. Because the filtering surface of the filter plate 51 is composed of multiple components of different materials, each group of blade assemblies 11 can scrape and shovel mud on the components of different materials of the filter plate 51 respectively, and can be opened separately as needed; different materials can be used for the cleaning parts, and different shoveling frequencies, angles and forces can be set, so as to more effectively complete the scraping and shoveling operations and prevent damage to the components of the filter plate 51.

[0058] like Figure 1 As shown, the X-axis moving unit 30 can move along the first direction, so that the first shoveling unit 10 and the second shoveling unit 20 can also move along the first direction to clean the filter plates 51 one by one; Figure 2 As shown, the X-axis moving unit 30 is provided with a positioning moving support 32 and a clamping mechanism 31. When in use, the positioning moving support 32 moves along the first direction, driving the clamping mechanism 31 to move along the first direction. The first direction refers to the direction from the pressing unit 53 of the filter press 50 to the end plate 52. The clamping mechanism 31 can identify the filter plate 51 to be cleaned during the movement, and then clamp the two ends of the filter plate 51. Driven by the positioning moving support 32, it moves in the opposite direction along the first direction to make the filter plate 51 away from other filter plates 51. When the filter plate 51 reaches a certain set position, there is enough space on both sides of the filter plate 51, which is convenient for the first shoveling unit 10 and the second shoveling unit 20 to scrape and shovel mud. After the cleaning is completed, the clamping mechanism 31 continues to move in the opposite direction along the first direction driven by the positioning moving support 32, so that the filter plate 51 can be gathered to the side close to the pressing unit 53, so as to realize the gathering of the filter plate 51. This process is controlled by the control unit 60, and the full automation of the cleaning operation of the filter plate 51 is realized.

[0059] In a specific embodiment, after the clamping unit 53 is reset, the distance between the clamping surface and the first filter plate 51 is 80 cm. After the clamping mechanism 31 clamps the filter plate 51, it moves in the opposite direction for 40 cm and then stops. At this time, there is 40 cm of space on each side of the filter plate 51, which is enough for the first mud shoveling unit 10 and the second mud shoveling unit 20 to perform cleaning operations simultaneously.

[0060] Furthermore, if Figure 1 , Figure 2 and Figure 6As shown, the X-axis moving unit 30 also includes a gantry 33; the positioning movable support 32 is arranged at the bottom of both ends of the gantry 33 along the third direction, and is slidably connected to the guide rail 40 arranged along the first direction, the guide rail is provided with an origin sensing plate 43, and the positioning movable support 32 is provided with a corresponding origin sensor 326.

[0061] In this embodiment, the first direction is the direction from the clamping unit 53 of the filter press 50 to the end plate 52, which is arranged in the horizontal direction. The guide rail 40 is arranged on both sides of the filter plate 51 along the first direction, and the origin sensing plate 43 is located close to the clamping unit 53. In the initial state, the origin sensor 326 of the positioning movable support 32 can sense the origin sensing plate 43. At this time, the first mud shoveling unit 10 is constructed to face the clamping surface of the clamping unit 53. After the device is started, the first mud shoveling unit 10 performs a cleaning operation. When the positioning movable support 32 moves to block the end plate sensor 44, it stops moving. At this time, the second mud shoveling unit 20 is constructed to face the filtering surface of the end plate 52 close to the previous filter plate 51 and performs a cleaning operation; then the positioning movable support 32 moves in the opposite direction until the origin sensor 326 senses the origin sensing plate 43, and all cleaning operations are completed at this time.

[0062] The second direction in this embodiment is the vertical direction, and the first mud shoveling unit 10 and the second mud shoveling unit 20 can rise or fall in the vertical direction; the third direction is perpendicular to the first direction and the second direction, and both ends of the gantry 33 extend along the third direction, and the bottom end height is higher than the top end of the filter plate 51 in the vertical direction; the positioning movable support 32 and the clamping mechanism 31 are relatively arranged along the third direction.

[0063] Furthermore, if Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the first mud shoveling unit 10 and the second mud shoveling unit 20 both include a lifting frame 12, and the blade assembly 11 is arranged on the lifting frame 12; the lifting frame 12 is arranged opposite to the gantry 33 along the first direction, and the gantry 33 is provided with a lifting drive mechanism 331 for driving the lifting frame 12 to rise or fall, a rising position sensor 332 for identifying the position of the lifting frame 12, a falling position sensor 333, and a rising limit sensor 334 and a falling limit sensor 335 for preventing the lifting frame 12 from offside.

[0064] Specifically, the gantry 33 is constructed with a accommodating space for accommodating the first mud shoveling unit 10 and the second mud shoveling unit 20, and two lifting drive mechanisms 331, rising position sensors 332, falling position sensors 333, rising limit sensors 334 and falling limit sensors 335 are provided, which are respectively used to control the first mud shoveling unit 10 and the second mud shoveling unit 20.

[0065] In a specific embodiment, Figure 5, Figure 7 and Figure 8 As shown, the gantry 33 is a frame structure as a whole, including a plurality of cross beams, a plurality of vertical poles and two guide rods 336. An upper sensor mounting seat is provided at the upper portion of the gantry 33 for mounting a rising position sensor 332, a rising limit sensor 334 and a rotating shaft drive sensor 113; a lower sensor mounting seat is provided at the lower portion of the gantry 33 for mounting a descending position sensor 333 and a descending limit sensor 335.

[0066] In this embodiment, the two lifting drive mechanisms 331 are relatively arranged on the crossbeam at the bottom of the gantry 33. When in the non-working state, the lifting frame 12 is located on the inner side of the gantry 33. When in the working state, the two lifting drive mechanisms 331 respectively drive the two lifting frames 12 to perform lifting movements, and the lifting frames 12 protrude downward from the gantry 33 when descending.

[0067] In this embodiment, the rising position sensor 332 and the descending limit sensor 335 are both through-beam sensors. When the signal of the through-beam sensor is blocked during the rising or descending process of the lifting frame 12, it means that the lifting frame 12 has risen or descended to the set position. At this time, the rising position sensor 332 or the descending limit sensor 335 transmits the signal to the controller (not shown), and the controller (not shown) controls the lifting frame 12 to stop running. This design can ensure the starting position of the lifting frame 12 for cleaning operations, ensure that the scraper assembly 11 can clean the upper and lower parts of the filtering surface of the filter plate 51, ensure the cleaning quality, and at the same time prevent the lifting frame 12 from being offside.

[0068] In this embodiment, Figure 7 and Figure 8 As shown, the rising limit sensor 334 is arranged above the rising position sensor 332, and the falling limit sensor 335 is arranged below the falling position sensor 333; when the rising position sensor 332 and the falling position sensor 333 fail, when the lifting frame 12 rises or falls and continues to rise or fall, the signal of the rising limit sensor 334 or the falling limit sensor 335 is blocked, which means that the lifting frame 12 has risen or fallen beyond the set position and an offside has occurred. The rising limit sensor 334 and the falling limit sensor 335 can transmit the signal to the controller (not shown) in time, and the controller (not shown) controls the lifting frame 12 to stop rising or falling, thereby improving the safety performance of the device.

[0069] Furthermore, if Figure 4 , Figure 5As shown, the lifting frame 12 includes a toothed rod 121, a rail wheel limiting assembly 122 and a limiting block 123: wherein the toothed rod 121 is arranged along the second direction, and is constructed with a rack arranged along the second direction, and the position of the rack is matched with the position of the lifting drive mechanism 331, and can be engaged with the first driving gear 3251 of the lifting drive mechanism 331; the rail wheel limiting assembly 122 is rollingly connected with the guide rod 336 of the gantry 33, and the guide rod 336 of the gantry 33 is arranged on both sides of the two toothed rods 121, which can limit the displacement of the lifting frame 12 during the lifting process; the limiting block 123 is convexly arranged on the lifting frame 12, and can be clamped with the crossbeam of the gantry 33 when the lifting frame 12 rises or descends to the set position, further ensuring the safety of the lifting of the lifting frame 12 and preventing it from being offside and detaching from the gantry 33.

[0070] In a specific embodiment, there are two toothed rods 121 on the lifting frame 12, which are arranged at intervals in the middle of the lifting frame 12; the lifting drive mechanism 331 is arranged in the middle of the gantry 33, and has two output ends, which are respectively connected to two first driving gears 3251, and the two first driving gears 3251 are respectively engaged with the toothed rods 121 on the same side, so that the lifting frame 12 can be smoothly lowered;

[0071] In this embodiment, there is a certain distance between the blade assemblies 11 of the first shoveling unit 10 and the second shoveling unit 20, and the distance is coordinated with the thickness of the filter plate 51, so that the two groups of blade assemblies 11 can simultaneously and respectively cling to the two filtering surfaces of the filter plate 51 during cleaning operations, and perform cleaning operations synchronously and efficiently.

[0072] In this embodiment, if Fig. 9 As shown, the rail wheel limiting assembly 122 includes two concentric wheels and two eccentric wheels, which are respectively arranged on both sides of the guide rod 336. It can clamp the guide rod 336 during rolling along the guide rod 336, and play a limiting role so that the lifting frame 12 can be lifted and lowered smoothly.

[0073] Furthermore, if Figure 2 , Fig.10 As shown, the clamping mechanism 31 is arranged on the positioning movable support 32, including a clamping jaw 311, a telescopic driver 312, a pull plate in place sensor 313 and a telescopic sensor 314; the pull plate in place sensor 313 can identify the filter plate 51 to be cleaned, and the telescopic driver 312 drives the clamping jaw 311 to be telescoped along the second direction to clamp or release the filter plate 51; the telescopic sensor 314 can identify the operating status of the telescopic driver 312.

[0074] The pull plate in place sensor 313 in the present application is a paired sensor, which is relatively arranged along the third direction; during the movement of the positioning movable support 32, when the filter plate 51 to be cleaned blocks the pull plate in place sensor 313, the pull plate in place sensor 313 transmits a signal to the controller (not shown), and the controller (not shown) controls the positioning movable support 32 to stop moving, and then controls the telescopic drive 312 to extend, driving the clamping jaw 311 to move along the second direction to clamp the filter plate 51 to be cleaned.

[0075] Specifically, the clamping jaw 311 is arranged at the output end of the telescopic driver 312, and is provided with a slot matching the thickness of the filter plate 51. When the telescopic driver 312 is extended, the clamping jaws 311 on both sides of the filter plate 51 approach each other, so that the two ends of the filter plate 51 are inserted into the slot and will not fall out, and can move synchronously in the opposite direction along the first direction with the positioning movable support 32.

[0076] In this embodiment, the telescopic sensor 314 is relatively arranged along the second direction, extending to the relatively inner side of the positioning movable support 32, and is located below the clamping claw 311. When the telescopic driver 312 is extended, it can block the signal of the telescopic sensor 314, and when the telescopic driver 312 is shortened, it will not block the signal of the telescopic sensor 314, so as to ensure that the operating status of the telescopic driver 312 can be sensed in time, and prevent the telescopic sensor 314 and the positioning movable support 32 from failing to cooperate and affecting the normal operation of the device.

[0077] Furthermore, if Fig.10 As shown, the positioning movable support 32 is also provided with an intermediate in-place sensor 321 and a gathering in-place sensor 322, both of which are used to identify the filter plate 51 that has been cleaned; the gathering in-place sensor 322 is arranged between the pull-plate in-place sensor 313 and the intermediate in-place sensor 321, and is close to the pull-plate in-place sensor 313, and the distance between it and the pull-plate in-place sensor 313 is set according to the thickness of the filter plate 51.

[0078] Specifically, when the plate pulling position sensor 313 identifies the filter plate 51 to be cleaned, the positioning movable support 32 drives the filter plate 51 to be cleaned to move in the opposite direction along the first direction, and the intermediate position sensor 321 is arranged at one end close to the clamping unit 53 of the filter press 50. When the filter plate 51 to be cleaned reaches a certain position, the intermediate position sensor 321 can be blocked by the previous filter plate 51 or the clamping unit 53 that has been cleaned and put in place. At this time, there is enough space on both sides of the filter plate 51 to be cleaned to accommodate the first mud shoveling unit 10 and / or the second mud shoveling unit 20 for cleaning operations. The intermediate position sensor 321 transmits a signal to the controller (not shown), and the controller (not shown) controls the positioning movable support 32 to stop moving, and controls the first mud shoveling unit 10 and / or the second mud shoveling unit 20 to start cleaning. After cleaning is completed, the positioning movable support 32 drives the filter plate 51 to continue to move in the opposite direction. When the signal of the folding-in-place sensor 322 is blocked by the last folded-in-place filter plate 51 or the clamping unit 53, a signal is sent to the controller (not shown). The controller (not shown) controls the telescopic driver 312 to retract, driving the clamping jaws 311 to reset and release the filter plate 51. When the telescopic sensor 314 recognizes that the telescopic driver 312 has retracted, a signal is sent to the controller (not shown). The controller (not shown) controls the positioning movable support 32 to continue to move in the first direction, repeating the clamping, cleaning and folding operations.

[0079] Furthermore, if Figure 4 , Figure 7As shown, the blade assembly 11 includes a blade 111, a shaft driver 112 for controlling the rotation of the blade 111, and a shaft drive sensor 113 for identifying the lifting frame 12; the blade assemblies 11 are arranged along the second direction. In this embodiment, a pin is provided at the bottom of the lifting frame 12, and the blades 111 of at least three blade assemblies 11 are connected to the same pin. The number of the shaft driver 112 and the blade 111 rotation sensor is set corresponding to the number of the blades 111. When not in use, the shape of the blade 111 is parallel to the second direction, that is, the vertical direction; when the lifting frame 12 starts to descend, the shaft drive sensor 113 recognizes the lifting frame 12 and transmits a signal to the controller (not shown); the controller (not shown) controls the shaft driver 112 to rotate, drives the corresponding blade 111 to rotate in the direction close to the filter plate 51, and its shape changes from the vertical direction to the inclined state, and abuts against the filter plate 51 to perform mud shoveling operations until the lifting frame 12 descends. To the set position, during this process, the scraper 111 can descend from the top of the filter plate 51 to the bottom of the filter plate 51 in the vertical direction, and multiple scrapers 111 cooperate to complete the mud scraping operation on the filtering surface of the entire filter plate 51; then the lifting frame 12 drives the scraper 111 to rise, and the shape of the scraper 111 does not change. After completing the mud scraping operation on the filter plate 51, the lifting frame 12 continues to rise to block the shaft drive sensor 113. After the shaft drive sensor 113 senses the lifting frame 12, it sends a signal to the controller (not shown); the controller (not shown) controls the shaft driver 112 to drive the corresponding scraper 111 to rotate in the opposite direction and reset, and converts from the inclined state to the vertical state; the rising position sensor 332 recognizes the lifting frame 12 and sends a signal. The controller (not shown) receives the signal port and controls the lifting drive mechanism 331 to stop running, and the lifting frame 12 stops rising, thereby ensuring that the mud scraping operation and the mud scraping operation can be effectively coordinated with the lifting of the lifting frame 12.

[0080] In this embodiment, if Figure 7 As shown, the shaft drive sensor 113 is disposed below the rising position sensor 332; the shaft driver 112 rotates 45 degrees to tilt the blade 111 downward by 45 degrees.

[0081] In a specific embodiment, the device is used to clean the silicon mud on the surface of the filter plate 51. The cleaning operation of the single-side filtering surface of each filter plate 51 includes one mud shoveling operation and one mud scraping operation, which can clean the silicon mud or residue on the surface of the filter plate 51. In some other embodiments, the cleaning operation can also be set to multiple mud shoveling operations and mud scraping operations according to the impurity conditions and cleanliness requirements on the surface of the filter plate 51, further ensuring the cleaning quality of the filter plate 51 and making the entire cleaning operation more standardized.

[0082] Furthermore, if Fig.10As shown, the positioning movable support 32 is provided with an upper limit wheel 323, a lower limit wheel 324 and an X-axis driving mechanism 325. In a specific embodiment, the two positioning movable supports 32 are driven by the same X-axis driving mechanism 325 to ensure that the two positioning movable supports 32 can move synchronously and stably; wherein the upper limit wheel 323 and the lower limit wheel 324 are relatively arranged on the same U-shaped mounting seat, the upper part of the guide rail 40 is provided with a slide bar 41, and the side is provided with a rack 42, the upper limit wheel 323 is rollingly connected with the slide bar 41, and the lower limit wheel 324 is rollingly connected with the bottom of the guide rail 40; as shown in FIG. Figure 3 , Fig.10 As shown, the X-axis driving mechanism 325 includes a servo motor, a reducer, two transmission shafts, two commutators and two second driving gears 3251. The second driving gears 3251 are engaged with the racks 42 on the sides of the guide rail 40. The servo motor drives the two second driving gears 3251 to rotate, thereby realizing the positioning of the movable support 32 and moving along the guide rail 40.

[0083] In some other embodiments of the present application, each of the two positioning movable supports 32 is provided with an X-axis driving mechanism 325 , and the two X-axis driving mechanisms 325 are arranged in coordination to enable the two positioning movable supports 32 to move synchronously.

[0084] Furthermore, if Figure 6 As shown, the guide rail 40 is also provided with an X-axis positive limit sensor 45, an X-axis negative limit sensor 46 and a limit clamp 47 for preventing the positioning movable support 32 from being offside. Specifically, the limit clamp 47 is arranged at both ends of the guide rail 40, the X-axis positive limit sensor 45 is arranged between the origin sensing plate 43 and the limit clamp 47 on the same side, and the X-axis negative limit sensor 46 is arranged between the end plate sensor 44 and the limit clamp 47 on the same side, which further ensures the safety of the movement of the X-axis movable unit 30.

[0085] In a specific implementation, the control unit 60 also includes a display screen, an electric cabinet, and an alarm device, etc., which are all arranged on the gantry 33 to facilitate operators to use and observe the operation of the entire device.

[0086] The utility model also proposes a filter press 50, which is equipped with the automatic cleaning device for the filter press as described above. Specifically, the filter plates 51 of the filter press 50 are arranged along a first direction, and mounting platforms are provided on both sides along the first direction, the guide rails 40 are provided on the mounting platforms on both sides of the filter plates 51, and the gantry 33 is erected above the filter plates 51. The overall device realizes automatic cleaning of the filter plates 51, and at the same time occupies a small area, saving space.

[0087] In this embodiment, the X-axis moving unit 30 is also provided with a housing for protecting the first mud shoveling unit 10 , the second mud shoveling unit 20 , the gantry 33 and the positioning moving support 32 .

[0088] The present application also proposes a filter press automatic cleaning method, comprising the following steps:

[0089] S1, resetting the pressing unit 53 of the filter press 50 and positioning the X-axis moving unit 30;

[0090] In a specific embodiment, resetting the pressing unit 53 of the filter press 50 includes controlling the pressing unit 53 of the filter press 50 to contract so that a set distance exists between the pressing unit 53 and the first filter plate 51 .

[0091] In this embodiment, the set distance between the pressing unit 53 and the first filter plate 51 after being reset is 80 cm.

[0092] In a specific embodiment, positioning the X-axis moving unit 30 includes determining whether the controller (not shown) receives a signal from the origin sensor 326; if not, the X-axis moving unit 30 is controlled to move until the origin sensor 326 senses the origin sensing plate 43 and sends a signal to the controller (not shown), and the controller (not shown) controls the X-axis moving unit 30 to stop moving.

[0093] S2, operate the first shoveling unit 10 to clean the compacting unit 53;

[0094] Specifically, the controller (not shown) controls the lifting drive mechanism 331 of the first shoveling unit 10 to start, while the second shoveling unit 20 does not move; the lifting drive mechanism 331 drives the lifting frame 12 to descend; when the lifting frame 12 descends to a certain position, it will block the signal of the shaft drive sensor 113. At this time, the shaft drive sensor 113 senses the lifting frame 12 and sends a signal to the controller (not shown); then the controller (not shown) controls the shaft driver 112 to start running, driving the blade 111 to rotate a set angle, so that the blade 111 rotates from a vertical state to an inclined state, and presses against the pressing surface of the pressing unit 53; as the lifting frame 12 moves downward at any time, the blade 111 performs a shoveling operation on the pressing surface, and when the lifting frame 12 descends to the set position When the lifting frame 12 is lifted up, the mud scraping operation is completed. At the same time, the sensor 333 that has fallen into place senses the lifting frame 12 and sends a signal to the controller (not shown). The controller (not shown) controls the lifting drive mechanism 331 to operate, driving the lifting frame 12 to rise, and the blade 111 performs the mud scraping operation. When the lifting frame 12 rises to a certain position, the mud scraping operation is completed. The shaft drive sensor 113 senses the lifting frame 12 and sends a signal to the controller (not shown). The controller (not shown) controls the shaft drive 112 to rotate in the opposite direction, driving the blade 111 to reset. The lifting frame 12 continues to rise until the rising sensor 332 senses the lifting frame 12 and sends a signal to the controller (not shown). Then the controller (not shown) controls the lifting drive mechanism 331 to stop running.

[0095] S3, controlling the X-axis moving unit 30 to move forward along the first direction, identifying and clamping the filter plate 51;

[0096] Specifically, during the positive movement of the X-axis moving unit 30 along the first direction, the filter plate 51 blocks the pull plate into position sensor 313, and the pull plate into position sensor 313 senses the filter plate 51 and sends a signal to the controller (not shown). Then the controller (not shown) controls the telescopic drive 312 to drive and operate, so that the clamp 311 extends along the second direction to clamp the filter plate 51.

[0097] It can be understood that in this embodiment, the cleaning operation is performed piece by piece starting from the first filter plate 51 close to the pressing unit 53 .

[0098] S4, controlling the X-axis moving unit 30 to move in the reverse direction, and simultaneously cleaning the two filter surfaces of the filter plate 51;

[0099] Among them, the X-axis moving unit 30 is controlled to move in the reverse direction, specifically including sending a signal to the controller (not shown) after the telescopic sensor 314 senses that the clamping claw 311 is extended; the controller (not shown) controls the X-axis moving unit 30 to move in the reverse direction along the first direction, that is, to move in the direction close to the clamping unit 53; when the X-axis moving unit 30 moves to a certain set position, the clamping unit 53 or the last filter plate 51 gathered in the clamping unit 53 blocks the middle in-place sensor 321, which means that the filter plate 51 to be cleaned has been moved into place, and the space on both sides thereof is sufficient for the first shoveling unit 10 and the second shoveling unit 20 to perform shoveling operations; at this time, the middle in-place sensor 321 senses the clamping surface of the clamping unit 53 or the last filter plate 51 gathered in the clamping unit 53, and sends a signal to the controller (not shown), and then the controller (not shown) controls the X-axis moving unit 30 to stop moving; then the controller (not shown) controls the first shoveling unit 10 and the second shoveling unit 20 to run synchronously, and the two filtering surfaces of the filter plate 51 are cleaned synchronously.

[0100] In this embodiment, the X-axis moving unit 30 drives the filter plate 51 to move 40 cm in the opposite direction. At this time, there is a 40 cm space on both sides of the filter plate 51, which can ensure that the first mud shoveling unit 10 and the second mud shoveling unit 20 can perform mud shoveling operations normally.

[0101] S5, controlling the X-axis moving unit 30 to continue to move in the reverse direction to gather the filter plates 51;

[0102] In this embodiment, after the filter plate 51 is cleaned, the X-axis moving unit 30 drives the filter plate 51 to continue to move in the opposite direction, that is, to move in the direction close to the clamping unit 53. When the clamping unit 53 or the last filter plate 51 that is gathered in the clamping unit 53 blocks the retraction sensor 322, it means that the filter plate 51 has moved to the vicinity of the clamping unit 53 or the last filter plate 51 that is gathered in the clamping unit 53. At this time, the retraction sensor 322 senses the clamping surface or the last filter plate 51 that is gathered in place, and sends a signal to the controller (not shown); after receiving the signal, the controller (not shown) controls the X-axis moving unit 30 to stop moving, and at the same time controls the telescopic driver 312 to retract, driving the clamp 311 to retract to release the filter plate 51.

[0103] At this time, after the telescopic sensor 314 senses the contraction of the clamping jaw 311, it sends a signal to the controller (not shown) again, so that the controller (not shown) controls the X-axis moving unit 30 to move along the first direction to clean the next filter plate 51 again.

[0104] S6, repeat steps S3, S4, and S5 until all filter plates 51 except the last plate 52 are cleaned;

[0105] Among them, during the operation of the first mud shoveling unit 10 and the operation of the second mud shoveling unit 20, when the rising position sensor 332 and / or the falling position sensor 333 fail, the lifting frame 12 cannot be sensed and the signal cannot be transmitted to the controller (not shown), the lifting frame 12 continues to rise or fall, and the rising limit sensor 334 or the falling limit sensor 335 is blocked. The rising limit sensor 334 or the falling limit sensor 335 senses the lifting frame 12 and sends a signal to the controller (not shown); the controller (not shown) controls the lifting drive motor to stop moving and issues an alarm, so that the operator can discover the fault in time to avoid safety accidents; if the rising limit sensor 334 or the falling limit sensor 335 also fails at the same time, the lifting frame 12 continues to rise or fall, and the limit block 123 can also timely clamp the gantry 33 to prevent the lifting frame 12 from being offside and causing danger.

[0106] S7, operate the second shoveling unit 20 to clean the end plate 52;

[0107] In this embodiment, after completing the cleaning and gathering of all filter plates 51 except the last plate 52, the controller (not shown) controls the X-axis moving unit 30 to move forward in the first direction; when the last plate sensor 44 is blocked, the second shoveling unit 20 faces the surface of the last plate 52 to be cleaned, and the last plate sensor 44 sends a signal to the controller (not shown), and the controller (not shown) controls the second shoveling unit 20 to run and clean the surface of the last plate 52 to be cleaned; after the cleaning is completed, the gathering function can be set as needed to gather the last plate 52 into place, or the last plate 52 can not be gathered.

[0108] In a preferred embodiment, when the end plate sensor 44 fails and fails to sense the X-axis moving unit, the X-axis moving unit 30 continues to move forward along the first direction until it blocks the X-axis positive limit sensor 45. The X-axis positive limit sensor 45 sends a signal, so that the controller (not shown) can control the X-axis moving unit 30 to stop moving, thereby preventing the X-axis moving unit 30 from escaping the guide rail 40. At the same time, the limit clamp 47 of the guide rail 40 can clamp the X-axis moving unit 30 when the X-axis positive limit sensor 45 is effective.

[0109] S8 . Reset the X-axis moving unit 30 .

[0110] In this embodiment, after completing all cleaning operations, the X-axis moving unit 30 moves in the opposite direction along the first direction until its origin sensor 326 senses the origin sensing plate 43, and sends a signal to the controller (not shown), so that the controller (not shown) can control the X-axis moving unit 30 to stop moving. Similarly, the X-axis negative limit sensor 46 and the limit clamp 47 on the same side ensure that the X-axis moving unit 30 will not move offside.

[0111] The advantages and positive effects of the utility model are:

[0112] (1) By arranging the first shoveling unit, the second shoveling unit, the positioning and moving support and the clamping mechanism, the fully automated operation of filter plate positioning, moving, cleaning and gathering is realized, without the need for manual plate pulling, which effectively reduces the difficulty of personnel operation and improves the cleaning efficiency;

[0113] (2) The first shoveling unit and the second shoveling unit can operate synchronously, realizing the synchronous cleaning of the filter surfaces on both sides of the filter plate, further improving the cleaning efficiency; at the same time, the two can also operate independently, and both are equipped with at least three independent scraper assemblies, which can be applied to different working conditions;

[0114] (3) The overall device design is scientific and reasonable, with high reliability and safety, and has good cleaning effect and stable cleaning quality.

[0115] The above is a detailed description of the embodiments of the utility model, but the contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
