Description

Technical Field

[0001] This utility model relates to the technical field of gantry filter presses, specifically a gantry filter press with a fully automatic filter residue discharge function. Background Technology

[0002] In the fields of wastewater treatment and solid-liquid separation, gantry filter presses are widely used due to their stable structure and high filtration efficiency. However, traditional gantry filter presses often rely on manual operation for the discharge and cleaning of filter cake after wastewater filtration, which has many shortcomings. In the existing technology, although some filter press devices can achieve basic filtration functions, there are still obvious defects in the filter cake discharge process. For example, when the filter cake is discharged, the filter plates need to be opened manually and the filter cake attached to the filter cloth needs to be cleaned manually. This is not only time-consuming and labor-intensive, reducing the overall work efficiency, but may also damage the filter cloth due to improper manual operation, increasing the equipment maintenance cost. Residual filter residue can clog the pores of the filter cloth, affecting the subsequent filtration effect and even causing the filter cloth to wear out more quickly, further shortening its service life. Manual cleaning of filter residue also poses safety hazards.

[0003] According to the patent application published on the Internet, a chamber filter press with filter residue collection function (authorization announcement number: CN218853551U) is described as including "thrust plate, base" etc. to achieve filtration.

[0004] Regarding the above description, the applicant believes the following issues exist: This chamber filter press with filter cake collection function uses a thrust plate and base to achieve filtration. During use, the filter press operates through a first filter cloth, a filter plate, and a second filter cloth. After filtration, the filter plates are separated, and when processing the filter cake, an external air pump injects air into the diaphragm through the air duct to inflate it and clean the filter cake. However, this method requires very high air pressure to completely discharge the filter cake, and it is inefficient and cannot achieve comprehensive cleaning, thus affecting the cleaning effect. Therefore, this filter press needs to be improved. Utility Model Content

[0007] Preferably, the water inlet pipe runs through the inside of the filter press body, and the extrusion plate is slidably connected to the inside of the filter press body, so that the four sets of filter cloths can be closed together under the action of the extrusion plate to filter the sewage.

[0008] Preferably, the first rotating shaft is rotatably connected inside the support frame, and the connecting frame is fixedly connected to the bottom of the front and rear sides of the filter plate, so as to ensure the stability of the second rotating shaft through the connecting frame.

[0009] Preferably, both the driving roller and the driven roller have knurled patterns on their surfaces, and these patterns are straight. The surfaces of the driving roller and the driven roller are coated with solvent-free epoxy resin to facilitate the passage of the knurled patterns and ensure that slippage does not occur when the filter cloth is rotated.

[0010] Preferably, the movable seat, filter plate, connecting frame, servo motor, first rotating shaft, driving roller, filter cloth, driven roller, second rotating shaft and support frame are arranged in four sets and symmetrically distributed inside the filter press body. The left side of the leftmost set of filter cloth is in contact with the right side of the head filter plate, and the right side of the rightmost set of filter cloth is in contact with the left side of the extrusion plate, so that the four sets can pass through and improve the filtration effect.

[0011] Preferably, the cleaning mechanism includes a support platform, which is fixedly connected to the inner side of the load-bearing frame. A second hydraulic cylinder is fixedly connected to the top of the support platform, and a movable platform is fixedly connected to the bottom of the second hydraulic cylinder. The movable platform is slidably connected to the inner side of the load-bearing frame. Fixed frames are fixedly connected to the front and rear sides of the movable platform, and a scraper is fixedly connected to the top of the fixed frames. The scraper is disposed around the filter cloth.

[0012] Preferably, the outer periphery of the top of the scraper is in contact with the outer periphery of the filter cloth.

[0013] Compared with the prior art, this utility model provides a gantry filter press with a fully automatic filter cake discharge function, which has the following beneficial effects: 1. This gantry filter press with fully automatic filter cake discharge function, through its slag discharge mechanism, uses a first hydraulic cylinder to push the extrusion plate to slide inside the filter press body, squeezing and pushing four sets of filter plates and filter cloths together. At this point, the filter cloths can be connected to the inlet pipe via external conveying equipment for wastewater transport. The wastewater is then sequentially transported through the head filter plate to the four sets of filter plates and filter cloths for filtration. When the filter cake needs cleaning after filtration, an external pulling plate device separates the four sets of filter plates. A servo motor drives the first rotating shaft to rotate the active roller. Through the transmission between the filter cloth and the active and driven rollers, the filter cloth can automatically circulate. After filtration, the filter cloth automatically discharges the filter cake, eliminating the need for manual cleaning and greatly improving slag discharge efficiency. The circular rotation of the filter cloth ensures even and comprehensive removal of the filter cake, preventing residue and guaranteeing thorough discharge. This maintains the filter cloth's excellent filtration performance and improves the quality of filter cake treatment.

[0014] 2. This gantry filter press with fully automatic filter cake discharge function, through its cleaning mechanism, makes the cleaning of the filter cloth more convenient and efficient during the slag discharge process. Combined with the automatic rotation of the filter cloth, the scraper can promptly remove the clumps of sludge and filter cake adhering to the surface of the filter cloth, preventing filter cake accumulation from causing wear on the filter cloth, extending the service life of the filter cloth, and reducing equipment maintenance costs. The fully automated slag discharge process reduces the wear and tear on equipment parts caused by manual cleaning, which helps to extend the overall service life of the filter press.

[0019] This utility model provides the following technical solution: Example 1 Please see Figure 1-5 This utility model provides a technical solution: a gantry filter press with fully automatic filter residue discharge function, including a support frame 1, a slag discharge mechanism 2 is provided at the top of the support frame 1, and a cleaning mechanism 3 is provided at the bottom of the slag discharge mechanism 2; The slag discharge mechanism 2 includes a filter press body 21, which is fixedly connected to the top of the support frame 1.

A first hydraulic cylinder 24 is fixedly connected to the right side of the filter press body 21, and a pressing plate 25 is fixedly connected to the left side of the first hydraulic cylinder 24. A movable seat 26 is slidably connected to the top of the filter press body 21, and a filter plate 27 is fixedly connected to the inside of the movable seat 26. A support frame 28 is fixedly connected to the top of the filter plate 27. A servo motor 29 is fixedly connected to the rear side of the support frame 28. A first rotating shaft 291 is fixedly connected to the front side of the servo motor 29. An active roller 292 is fixedly connected to the periphery of the first rotating shaft 291. A filter cloth 293 is driven to the periphery of the active roller 292. A driven roller 294 is driven to the inner side of the filter cloth 293. A second rotating shaft 295 is fixedly connected inside the driven roller 294. A connecting frame 296 is rotatably connected to the periphery of the second rotating shaft 295. The filter cloth 293 is located on the right side of the head filter plate 23 and the left side of the extrusion plate 25.

[0020] The inlet pipe 22 runs through the inside of the filter press body 21, and the extrusion plate 25 is slidably connected to the inside of the filter press body 21, so that the four sets of filter cloths 293 can be closed under the action of the extrusion plate 25 to filter the sewage.

[0021] The first rotating shaft 291 is rotatably connected inside the support frame 28, and the connecting frame 296 is fixedly connected to the bottom of the front and rear sides of the filter plate 27, so as to ensure the stability of the second rotating shaft 295 through the connecting frame 296.

[0022] Both the drive roller 292 and the driven roller 294 have knurled patterns on their surfaces, which are straight lines. The surfaces of the drive roller 292 and the driven roller 294 are coated with solvent-free epoxy resin to facilitate the passage of the knurled patterns and ensure that there is no slippage when driving the filter cloth 293 to rotate.

[0023] The movable seat 26, filter plate 27, connecting frame 296, servo motor 29, first rotating shaft 291, driving roller 292, filter cloth 293, driven roller 294, second rotating shaft 295 and support frame 28 are arranged in four sets and symmetrically distributed inside the filter press body 21. The left side of the leftmost filter cloth 293 is in contact with the right side of the head filter plate 23, and the right side of the rightmost filter cloth 293 is in contact with the left side of the extrusion plate 25, so that the four sets can pass through and improve the filtration effect.

[0024] Example 2 Please see Figure 1-5Furthermore, based on Embodiment 1, the cleaning mechanism 3 further includes a support platform 32, which is fixedly connected to the inner side of the load-bearing frame 1. A second hydraulic cylinder 31 is fixedly connected to the top of the support platform 32, and a moving platform 33 is fixedly connected to the bottom of the second hydraulic cylinder 31. The moving platform 33 is slidably connected to the inner side of the load-bearing frame 1, and a fixed frame 34 is fixedly connected to the front and rear sides of the moving platform 33. A scraper 35 is fixedly connected to the top of the fixed frame 34, and the scraper 35 is disposed around the filter cloth 293.

[0025] The top periphery of the scraper 35 is in contact with the periphery of the filter cloth 293. Two sets of the second hydraulic cylinder 31, support platform 32 and moving platform 33 are provided and symmetrically distributed on the left and right sides of the fixed frame 34. By setting two sets, it is easy to ensure the stability when driving the fixed frame 34 and the scraper 35 to rise and fall.

[0026] In actual operation, when this device is used, the first hydraulic cylinder 24 pushes the extrusion plate 25 to slide inside the filter press body 21, which can squeeze and push the four sets of filter plates 27 and filter cloth 293, so that the four sets of filter cloth 293 are in a closed state. At this time, the wastewater can be transported through the external conveying equipment and connected to the water inlet pipe 22. The wastewater is then transported through the head filter plate 23 to the four sets of filter plates 27 and filter cloth 293 in sequence to filter the wastewater. When the filter residue needs to be cleaned after filtration, the four sets of filter plates 27 are separated by the external pulling plate device. At the same time, the second hydraulic cylinder 31 drives the moving table 33 and the fixed frame 34 to move, and adjusts the height of the scraper 35 so that the top outer periphery of the scraper 35 contacts the outer periphery of the filter cloth 293. At this point, the first rotating shaft 291 can be driven by the servo motor 29 to drive the active roller 292 to rotate. Through the transmission cooperation between the filter cloth 293, the active roller 292, and the driven roller 294, the filter cloth 293 can automatically circulate. After the filter pressing is completed, the filter cloth 293 can automatically discharge the filter residue without manual cleaning, which greatly improves the slag discharge efficiency. The rotation of the annular filter cloth 293 can evenly and comprehensively carry out the filter residue, avoid filter residue residue, ensure the thoroughness of filter residue discharge, maintain the good filtration performance of the filter cloth 293, and improve the processing quality of the filter residue. Under the action of the scraper 35, the clumps of sludge and filter residue attached to the surface of the filter cloth 293 can be removed in time, preventing the filter residue from accumulating and causing wear to the filter cloth 293, extending the service life of the filter cloth 293. The fully automated sludge discharge process reduces the wear and tear on equipment parts caused by manual cleaning, while improving efficiency. Both the active roller 292 and the driven roller 294 have knurled patterns on their surfaces, which are straight lines. The surfaces of the active roller 292 and the driven roller 294 are coated with solvent-free epoxy resin. The knurled patterns ensure that there will be no slippage when the filter cloth 293 is rotated. In this application, the first hydraulic cylinder 24, two sets of second hydraulic cylinders 31, and servo motor 29 need to be connected to the same PLC controller to ensure the coordinated operation of the equipment. Furthermore, the PLC controller is existing technology, and those skilled in the art are well aware of the specific operation methods and steps of this controller. Therefore, this application will not describe it in detail.
