Description

Technical Field

[0001] This invention belongs to the technical field of filter press equipment, specifically a dewatering filter press for sludge treatment. Background Technology

[0002] When a filter press is in use, a sludge cake will form between the filter plates. Ideally, the sludge cake should fall off smoothly after the adjacent filter plates are separated. However, due to factors such as equipment aging and limitations of actual working conditions, the sludge cake needs to be removed manually. That is, workers use a handheld scraper to remove the sludge cake from the filter plates. This operation not only restricts the continuous and uninterrupted use of the filter press, but also requires a lot of labor costs.

[0003] Therefore, this application proposes a dewatering filter press for sludge treatment. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides the following technical solution: a dewatering filter press for sludge treatment, comprising a plate pulling trolley and a fixed base, wherein a guide rail is provided through the fixed base, the arrangement direction of the guide rail is the same as the movement direction of the plate pulling trolley, the plate pulling trolley is connected to the fixed base, a support rod is fixedly connected to the upper end of the fixed base, and two symmetrically arranged first limiting frames are installed on the support rod;

[0005] A second limiting frame is also fixedly connected to one side of the first limiting frame. There is a gap between the second limiting frame and the first limiting frame. The filter plate is located in the gap. The first limiting frame and the second limiting frame form a sludge scraping assembly.

[0006] The sludge scraping assembly has a sludge scraping rope and an elastic rope, with the sludge scraping rope located below the elastic rope. The sludge scraping rope can contact the surface of the filter plate. During the up-and-down movement of the sludge scraping assembly, the elastic rope can undergo elastic deformation and move away from the surface of the filter plate. After moving to the farthest position, it retracts in the opposite direction to pat the surface of the filter plate.

[0007] Preferably, a first gear is provided inside the support rod, the first gear is driven by a drive motor, and a first rack is provided on the surface of the first limiting frame. The first gear and the first rack cooperate to enable the first limiting frame to move up and down.

[0008] Preferably, the first limiting frame is movable up and down, and a rotating plate is provided on the first limiting frame. A sludge scraping rope is provided on the rotating plate. The sludge scraping rope can adhere to the surface of the filter plate as the rotating plate rotates, so that when the first limiting frame moves downward, the sludge scraping rope can scrape off the sludge on the surface of the filter plate. A second gear is provided inside the first limiting frame, and the side of the second gear extends outside the first limiting frame. A second rack is also provided inside the support frame. The second gear can cooperate with the second rack. One end of the first connecting rope is connected to the surface of the second gear, and the other end of the first connecting rope is connected to the rotating frame. When the first limiting frame moves upward to a predetermined position, the second gear can rotate and pull the first connecting rope, so that the rotating frame is in a vertical state.

[0009] Preferably, a rotating shaft is fixedly connected to the rotating frame, and a torsion spring is sleeved on the rotating shaft. A toggle mechanism is provided inside the rotating frame. The toggle mechanism includes a rotating wheel, which is mounted on a fixed frame and connected to the fixed frame and the rotating frame by a first spring. The other end of the first connecting rope is connected to the fixed frame, and a fixing block is provided on the first connecting rope. When the first connecting rope is pulled, the fixing block can cooperate with the rotating frame to limit the slippage of the first connecting rope.

[0010] Preferably, a circulating actuating wheel is fixedly connected to the axis of the rotating wheel, an elastic rope is fixedly connected to the fixed frame, and a sliding pull rod is also provided on the fixed frame. The pull rod can pull the elastic rope to one side. The surface of the circulating actuating wheel is evenly provided with teeth, and the circulating actuating wheel can mesh with the pull rod.

[0011] Preferably, two ropes are arranged vertically on the side of the second limiting frame facing the first limiting frame, and the ropes can contact the surface of the filter plate.

[0012] Preferably, the second limiting frame has an internal mounting base shaped like a "[", the ends of the two ropes can be mounted on different end faces of the mounting base, and a second spring is provided between the mounting base and the second limiting frame. A pull wheel is provided above the mounting base, the side of the pull wheel extends out of the second limiting frame and can contact the side of the support rod. One end of the second connecting rope is fixed to the surface of the spindle of the pull wheel, and the other end of the second connecting rope is fixed to the mounting base. When the pull wheel is separated from the support rod, the mounting base can extend out of the second limiting frame.

[0013] Preferably, the rope located above the mounting base is an elastic rope, and the mounting base has a toggle mechanism that can toggle the elastic rope; the rope located below the mounting base is a mud scraper rope.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When this device is implemented, the fixed base moves together with the plate pulling trolley. Since the plate pulling trolley can pull and separate one filter plate at a time, this device, based on this feature, in conjunction with the use of the first limiting frame, can clean the mud cake on each filter plate in turn. The use of the mud scraping rope not only ensures the removal of mud cake, but also makes it lightweight, easy to use, and convenient for subsequent replacement and maintenance.

[0016] By incorporating elastic ropes, after the sludge cake is scraped off, the scraping ropes can tap the surface of the filter plate to prevent any remaining sludge from adhering to it, thus ensuring that the sludge on the filter plate surface is completely removed. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] Depend on Figure 1-7 The present invention discloses a dewatering filter press for sludge treatment, including a pull plate trolley 3 and a fixed base 1. A guide rail 2 is provided through the fixed base 1 to limit the movement trajectory of the fixed base 1 and to bear the load of the fixed base 1. The arrangement direction of the guide rail 2 is the same as the movement direction of the pull plate trolley 3. The pull plate trolley 3 is connected to the fixed base 1. A support rod 4 is fixed to the upper end of the fixed base 1, and two symmetrically arranged first limiting frames 6 are installed on the support rod 4.

[0028] A second limiting frame 22 is also fixedly connected to one side of the first limiting frame 6. There is a gap between the second limiting frame 22 and the first limiting frame 6. The filter plate is located in the gap. The first limiting frame 6 and the second limiting frame 22 form a sludge scraping assembly.

[0029] The sludge scraping assembly has a scraping rope 11 and an elastic rope 12, with the scraping rope 11 located below the elastic rope 12. The scraping rope 11 can contact the surface of the filter plate. During the up-and-down movement of the scraping assembly, the elastic rope 12 can undergo elastic deformation and move away from the surface of the filter plate. After moving to the farthest position, it retracts in the opposite direction to pat the surface of the filter plate, thereby shaking off the sludge on the filter plate.

[0030] In actual production, filter press equipment is mostly arranged side by side to increase the speed of wastewater treatment. However, the technical solution of this application, by setting two symmetrically arranged first limiting frames 6, can simultaneously remove sludge from two adjacent filter press equipment.

[0031] When this device is implemented, the fixed base 1 moves together with the pull plate trolley 3. Since the pull plate trolley 3 can pull and separate one filter plate at a time, this device, based on this feature, in conjunction with the use of the first limiting frame 6, can clean the mud cake on each filter plate in turn. The use of the mud scraping rope 11 not only ensures the removal of mud cake, but also has small weight, is easy to use, and is easy to replace and maintain later.

[0032] After the mud cake is scraped off, the scraper rope 11, in order to avoid some mud still adhering to the surface of the filter plate, can beat the surface of the filter plate by setting the elastic rope 12, thereby further ensuring that the mud on the surface of the filter plate is completely removed.

[0033] The second limiting frame 22, in conjunction with the first limiting frame 6, can clean different sides of the filter plate. In practice, the second limiting frame 22 and the first limiting frame 6 are equipped with identical scraping ropes 11 and elastic ropes 12 on their sides facing the filter plate to ensure thorough removal of sludge.

[0034] A first gear 5 is installed inside the support rod 4. The first gear 5 is driven by a drive motor. A first rack 7 is installed on the surface of the first limiting frame 6. The first gear 5 and the first rack 7 cooperate to enable the first limiting frame 6 to move up and down. The drive motor drives the first gear 5, and the first gear 5 cooperates with the first rack 7 to move the first limiting frame 6 up and down. The drive motor can drive the first gear 5 through gear meshing, belts, or other means.

[0035] As a first embodiment of the mud-scraping rope 11 and the elastic rope 12, and taking the mud-scraping rope 11 and the elastic rope 12 being disposed on the first limiting frame 6 as an example, it has the following characteristics:

[0036] The first limiting frame 6 can move up and down, and a rotating plate 8 is provided on the first limiting frame 6. A scraping rope 11 is provided on the rotating plate 8. The scraping rope 11 can be close to the surface of the filter plate as the rotating plate 8 rotates. A second gear 14 is provided inside the first limiting frame 6. The side of the second gear 14 extends outside the first limiting frame 6. A second rack 15 is also provided inside the support frame 4. The second gear 14 can cooperate with the second rack 15. One end of the first connecting rope 13 is connected to the surface of the second gear 14. The other end of the first connecting rope 13 is connected to the rotating frame 8. When the first limiting frame 6 moves upward to a predetermined position, the second gear 14 can rotate and pull the first connecting rope 13, so that the rotating frame 8 is in a vertical state.

[0037] When the first limiting frame 6 is above the filter plate, the rotating frame 8 is in a vertical position to avoid interference between the rotating frame 8 and the filter plate. When the first limiting frame 6 moves downward and the rotating frame 8 moves to one side of the filter plate, the rotating frame 8 can rotate, so that the scraper rope 11 contacts the side of the filter plate.

[0038] A rotating shaft 9 is fixedly connected to the rotating frame 8, and a torsion spring 10 is sleeved on the rotating shaft 9.

[0039] The rotating frame 8 is equipped with a toggle mechanism, which includes a rotating wheel 16 mounted on a fixed frame 17. The fixed frame 17 and the rotating frame 8 are connected by a first spring 20. The other end of the first connecting rope 13 is connected to the fixed frame 17, and a fixing block 21 is provided on the first connecting rope 13. When the first connecting rope 13 is pulled, the fixing block 21 can cooperate with the rotating frame 8 to restrict the sliding of the first connecting rope 13. That is, under the action of the fixing block 21, when the first connecting rope 13 moves to a predetermined position in one direction, the continued pulling of the first connecting rope 13 will cause the rotating frame 8 to rotate together. When the first connecting rope 13 moves in the other direction, the fixing block 21 will not restrict its movement.

[0040] The use of the first spring 20 allows the fixed frame 17 to move when the tension on the first connecting rope 13 is removed, causing the side of the rotating wheel 16 to extend outside the rotating frame 8, at which point the rotating wheel 16 can contact the surface of the filter plate. In order for the rotating wheel 16 to rotate on the surface of the filter plate, a rubber pad can be provided on the surface of the rotating wheel 16 to achieve an anti-slip effect.

[0041] When the first limiting frame 6 moves upward, the second gear 14 can engage with the second rack 15, thereby causing the second gear 14 to rotate. The rotation of the second gear 14 will cause the first connecting rope 13 to wrap around the surface of the second gear 14. At this time, the first connecting rope 13 first pulls the fixed frame 17 to move, and then pulls the rotating wheel 16 back into the rotating frame 8. Then the fixing block 21 on the first connecting rope 13 is locked on the rotating frame 8. Then, as the first connecting rope 13 continues to be pulled, the rotating frame 8 is pulled back to the vertical state.

[0042] When the torsion spring 10 is in a free state, it can cause the rotating frame 8 to rotate to an inclined state.

[0043] A circulating actuating wheel 18 is fixedly connected to the axis of the rotating wheel 16, an elastic rope 12 is fixedly connected to the fixed frame 17, and a sliding pull rod 19 is also provided on the fixed frame 17. The pull rod 19 can pull the elastic rope 12 to one side. The surface of the circulating actuating wheel 18 is evenly provided with teeth, and the circulating actuating wheel 18 can mesh with the pull rod 19.

[0044] When the rotating wheel 16 contacts the surface of the filter plate, the rotating wheel 16 can rotate as the first limiting frame 6 moves downward. During the rotation, the circulating actuating wheel 18 can actuate the pulling rod 19, so that the pulling rod 19 can pull the elastic band 12 away from the surface of the filter plate. When the area without teeth on the surface of the circulating actuating wheel 18 contacts the pulling rod 19, the elastic rope 12 can instantly reset and beat the surface of the filter plate under the action of the elastic rope 12. During implementation, the elasticity of the elastic rope 12 needs to be controlled to avoid damage to the filter plate.

[0045] The pull rod 19 slides in the groove inside the rotating frame 8 to limit its movement trajectory and prevent it from sliding outside the rotating frame 8.

[0046] The size of the fixing block 21 is larger than the channel through which the first connecting rope 13 passes.

[0047] As a second embodiment of the mud-scraping rope 11 and the elastic rope 12, and taking the mud-scraping rope 11 and the elastic rope 12 being mounted on the second limiting frame 22 as an example, it has the following characteristics:

[0048] The first limiting frame 6 and the second limiting frame 22 are fixed together. Two ropes 23 are arranged vertically and horizontally on the side of the second limiting frame 22 facing the first limiting frame 6, and the ropes 23 can contact the surface of the filter plate.

[0049] The second limiting frame 22 has an internal mounting base 24, which is shaped like a "[". The ends of the two ropes 23 can be respectively mounted on different end faces of the mounting base 24. A second spring 25 is provided between the mounting base 24 and the second limiting frame 22. A pull wheel 26 is provided above the mounting base 24. The side of the pull wheel 26 extends out of the second limiting frame 22 and can contact the side of the support rod 4. A spindle 27 is fixedly connected to the axis of the pull wheel 26. One end of a second connecting rope 28 is fixedly connected to the surface of the spindle 27. The other end of the second connecting rope 28 is fixedly connected to the mounting base 24. When the pull wheel 26 is separated from the support rod 4, the mounting base 24 can extend out of the second limiting frame 22. The rotation of the pull wheel 26 can be achieved by a gear and rack mechanism or by the pull wheel 26 moving in contact with the support rod 4.

[0050] The rope 23 located above the mounting base 24 is an elastic rope 12, and there is a toggle mechanism inside the mounting base 24. The toggle mechanism can toggle the elastic rope 12. The rope 23 located below the mounting base 24 is a mud scraper rope 11.

[0051] In this embodiment, the actuating mechanism includes a rotating wheel 16, a fixed frame 17, a circulating actuating wheel 18, and a pulling rod 19, and its structure is the same as that in the first embodiment, except that the surface of the rotating wheel 16 extends outside the mounting base 24, and the fixed frame 17 is fixed inside the mounting base 24. When the second connecting rope 28 pulls the mounting base 24 back into the second limiting frame 22, the rotating wheel 16 separates from the filter plate.
