Description

Technical Field

[0001] This utility model belongs to the technical field of flat disc filter machines, specifically a flat disc filter machine with a filter cloth washing mechanism. Background Technology

[0002] The flat disc filter is a high-efficiency solid-liquid separation device, widely used in industries such as alumina, phosphoric acid, titanium dioxide, inorganic salts and fine chemicals. Its working principle is based on vacuum adsorption technology. The slurry is evenly distributed by the rotation of the flat disc, and the filter cloth separates the filtrate from the solid particles under vacuum. After forming a filter cake, it is washed twice in reverse and unloaded by the discharge screw, realizing continuous separation and washing.

[0003] During the operation of existing flat plate filters, a thick filter cake layer remains on the surface of the filter cloth after each filtration cycle, directly limiting the effective processing capacity of the equipment. At the same time, during long-term operation, the filter cloth is repeatedly subjected to vacuum adsorption, causing fine particles in the slurry to gradually form scales on the surface of the filter cloth, eventually forming a colloidal deposit layer. This dual mechanism causes the effective filtration area of ​​the filter cloth to continuously decrease and the filtration resistance to increase significantly. This not only leads to a significant decrease in overall filtration efficiency, but also causes production capacity fluctuations and unstable product quality due to incomplete cleaning. Therefore, improvements are needed. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 7 As shown, this utility model provides a flat disc filter with a filter cloth washing mechanism, including a flat disc 1. A filter cloth 2 is fixedly installed inside the top of the flat disc 1. A movable plate 3 is movably installed inside the top left side of the flat disc 1. A first cleaning brush 4 is fixedly installed on the front side of the bottom of the movable plate 3, and a second cleaning brush 5 is fixedly installed on the rear side of the bottom of the movable plate 3. The bottoms of both the first cleaning brush 4 and the second cleaning brush 5 are movably connected to the top of the filter cloth 2. A movable brush 6 is movably installed on the bottom of the movable plate 3, located between the first cleaning brush 4 and the second cleaning brush 5. The top of the movable brush 6 is fixedly installed... There is a connecting block 7, the outer surface of the connecting block 7 is movably connected to the inner wall of the movable plate 3, the top of the connecting block 7 is fixedly installed with a movable frame 8, the outer surface of the movable frame 8 is movably connected to the top of the movable plate 3, the top of the movable plate 3 is fixedly installed with a connecting plate 28, the top of the inner surface of the connecting plate 28 is fixedly installed with a first motor 9, the other end of the output shaft of the first motor 9 is fixedly connected with a rotating shaft 10, the outer surface of the rotating shaft 10 is fixedly sleeved with a rotating plate 11, the rear end of the rotating plate 11 is fixedly sleeved with a round block 12, the outer surface of the round block 12 is movably connected to the inner surface of the movable frame 8.

[0021] When the flat plate 1 drives the filter cloth 2 to rotate, the first cleaning brush 4 and the second cleaning brush 5 can clean the particulate material on the top of the filter cloth 2. Since the bristles at the bottom of the first cleaning brush 4 and the second cleaning brush 5 are staggered, the particulate material can be prevented from accumulating between the first cleaning brush 4 and the second cleaning brush 5. When the first motor 9 is started, the rotating shaft 10 will drive the rotating plate 11 to rotate, causing the round block 12 to squeeze and push the inner surface of the movable frame 8, thereby driving the movable frame 8 to move back and forth, which in turn causes the movable brush 6 to move back and forth, thereby cleaning the particulate matter on the outer surface of the filter cloth 2.

[0022] Among them, a cylinder 15 is movably sleeved on the bottom of the outer surface of the flat plate 1, a support platform 14 is fixedly connected to the bottom of the cylinder 15, a base plate 13 is fixedly connected to the bottom of the support platform 14, and a toothed ring 16 is fixedly sleeved on the bottom of the outer surface of the flat plate 1.

[0023] When the toothed ring 16 rotates, it will cause the flat plate 1 to rotate inside the cylinder 15.

[0024] The second motor 17 is fixedly installed on the left side of the top of the support platform 14. The other end of the output shaft of the second motor 17 is fixedly connected to a round shaft 18. A gear 19 is fixedly sleeved on the outer surface of the round shaft 18. The outer surface of the gear 19 meshes with the outer surface of the gear ring 16.

[0025] The operator can start the second motor 17 to make the round shaft 18 drive the gear 19 to rotate. Since the outer surface of the gear 19 meshes with the outer surface of the gear ring 16, the gear 19 can drive the gear ring 16 to rotate.

[0026] The base plate 13 is fixedly mounted with a bracket 20. A vertical rod 21 is movably connected inside the left end of the bracket 20. There are two vertical rods 21. The bottom ends of the two vertical rods 21 are fixedly connected to the top of the connecting plate 28. The top of the vertical rods 21 is fixedly connected to the top plate 22.

[0027] When the vertical rod 21 rises, it will drive the connecting plate 28 to rise, thereby driving the movable plate 3 to move upward, which in turn can adjust the distance between the first cleaning brush 4, the second cleaning brush 5 and the movable brush 6 and the filter cloth 2.

[0028] The bracket 20 has a mounting block 23 fixedly installed on its top, and a drive motor 24 is fixedly installed on the right side of the mounting block 23.

[0029] By setting the mounting block 23, the mounting block 23 can support and install the drive motor 24.

[0030] The other end of the output shaft of the drive motor 24 is fixedly connected to a double threaded rod 25. The left end of the double threaded rod 25 passes through the mounting block 23 and extends into the interior of the mounting block 23 and is movably sleeved with the inner wall of the mounting block 23.

[0031] The operator starts the drive motor 24, which causes the double threaded rod 25 to rotate. The threads on the left and right sides of the outer surface of the double threaded rod 25 are in opposite directions.

[0032] The double threaded rod 25 has a moving block 26 threadedly connected to both the left and right sides of its outer surface, and the bottom of the moving block 26 is movably connected to the top of the bracket 20.

[0033] When the double threaded rod 25 rotates, it will cause the two moving blocks 26 to move towards or away from each other.

[0034] The movable block 26 has push-pull rods 27 hinged to both its front and rear sides, and the top of the push-pull rods 27 is hinged to the side of the top plate 22.

[0035] When the two moving blocks 26 move toward each other, they will push the top plate 22 upward through the push-pull rod 27, thereby driving the vertical rod 21 upward.

[0036] Among them, a support frame 29 is fixedly installed on the top of the base plate 13, and a washing assembly 30 located above the filter cloth 2 is fixedly installed on the outer surface of the support frame 29.

[0037] By setting up the washing component 30, the washing component 30 can spray cleaning liquid to wash the material, and the cleaning liquid can enter the lower part of the movable plate 3, thereby working with the first cleaning brush 4, the second cleaning brush 5 and the movable brush 6 to clean the filter cloth 2.

[0038] Among them, a discharge assembly 31 is fixedly installed on the rear side of the top of the base plate 13, and a baffle plate 32 located between the discharge assembly 31 and the movable plate 3 is fixedly installed on the rear side of the top of the base plate 13. The outer surface of the baffle plate 32 is movably connected to the inner surface of the flat plate 1.

[0039] By setting up the baffle plate 32, the baffle plate 32 can block the cleaning liquid, preventing the cleaning liquid from contacting the filter cake and affecting the unloading assembly 31 to unload the filter cake.

[0040] Working principle and usage process of this utility model: The operator connects the vacuum equipment to the pipes inside the flat plate 1 and starts the second motor 17, causing the round shaft 18 to drive the gear 19 to rotate. The gear 19 then drives the gear ring 16 to rotate, causing the flat plate 1 to rotate. This allows the material on top of the filter cloth 2 to be filtered. When passing the unloading assembly 31, its activation unloads the filter cake from the top of the filter cloth 2. After unloading, as the filter cloth passes under the movable plate 3, the first cleaning brush 4 and the second cleaning brush 5 clean the particulate material adhering to the surface of the filter cloth 2 as it rotates, thus improving the adhesion between the material and the filter cloth 2. The loosening of the filter cloth 2 is caused by the starting of the first motor 9, which will cause the rotating shaft 10 to drive the rotating plate 11 to rotate. This causes the round block 12 to squeeze and push the inner surface of the movable frame 8, causing the movable frame 8 to move back and forth. This, in turn, drives the movable brush 6 to move back and forth through the connecting block 7, so that the movable brush 6 can clean the outer surface of the filter cloth 2 back and forth, thereby loosening the gelatinous deposit layer on the surface of the filter cloth 2. During the cleaning process, the washing component 30 can spray cleaning liquid to wash the material, and the cleaning liquid can enter the lower part of the movable plate 3, thereby working with the first cleaning brush 4, the second cleaning brush 5 and the movable brush 6 to clean the filter cloth 2.

[0041] When washing filter cloth 2 for different usage conditions, the drive motor 24 can be started to make the double threaded rod 25 rotate, thereby driving the two moving blocks 26 to move in opposite directions. This causes the push-pull rod 27 to push the top plate 22 upward, which in turn drives the connecting plate 28 upward through the vertical rod 21. This allows the movable plate 3 to rise, which in turn causes the first cleaning brush 4, the second cleaning brush 5, and the movable brush 6 to rise. This allows the distance between the first cleaning brush 4, the second cleaning brush 5, and the movable brush 6 and the filter cloth 2 to be adjusted according to the thickness of the gelatinous deposit layer on the surface of the filter cloth 2.
