Description

Technical Field

[0001] The invention belongs to the technical field of filtering equipment, in particular to a filtering device for producing polymer cement waterproof coatings. Background Art

[0002] Polymer cement waterproofing coating, abbreviated as JS waterproofing coating, where J refers to polymer and S to cement, is a two-component water-based waterproofing coating made from polymer emulsions such as acrylates and ethylene vinyl acetate, and cement, along with fillers and other additives. During the production process, polymer cement waterproofing coating requires filtration to separate the solids from the liquid.

[0003] Patent publication number CN219722068U discloses a filter press device for the production of polymer cement waterproof coatings. Its technical solution includes a housing, with side panels mounted above both outer walls of the housing, a second hydraulic cylinder mounted on the upper surface of the side panels, a second hydraulic telescopic rod mounted on the top of the second hydraulic cylinder, a top plate mounted on the top of the second hydraulic telescopic rod, a first hydraulic cylinder mounted at the center of the top surface of the top plate, and a first hydraulic telescopic rod mounted at the bottom of the first hydraulic cylinder. This patent facilitates the disassembly, replacement, or cleaning of plate-type filter presses. It also facilitates control of the pressure exerted by the pressure plate on the plate-type filter press, preventing damage to the plate-type filter press due to excessive pressure and poor filtration results due to insufficient pressure, resulting in high practicality.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] The polymer cement waterproof coating raw materials are placed on the filter press, and the pressure plate is driven to squeeze the raw materials on the filter press, thereby achieving solid-liquid separation of the raw materials. However, when the raw materials are placed on the filter, they may be in a piled state, and the piled raw materials will form a thicker material layer. The resistance encountered by the liquid when passing through the material layer increases, affecting the solid-liquid separation efficiency. In addition, the solid raw materials will adhere to the surface of the filter and the pressure plate due to being squeezed, making it inconvenient to remove them from the filter and the pressure plate, resulting in the solid raw materials forming a layer of barrier on the filter and the pressure plate, affecting the subsequent filtration efficiency.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Please refer to Figures 1-8 The present invention provides a technical solution: a filtering device for producing polymer cement waterproof coating, comprising a filter press 1, a support frame 4 is fixedly connected to one side of the outer wall of the filter press 1, a filter plate 6 is fixedly connected to one side of the inner cavity wall of the filter press 1, two slide rods 3 are slidably connected to one side of the upper end of the filter press 1, a pressing plate 5 is fixedly connected to the lower end of the slide rod 3, a feeding port 13 is provided on one side of the pressing plate 5, a drain port 33 is provided at the bottom of the filter press 1, and a raw material flattening and collecting integrated component is also provided on the pressing plate 5;

[0034] The raw material flattening and collecting integrated assembly includes a support plate 7 fixedly connected to one side of the upper end face of the pressing plate 5, and the upper end side of the support plate 7 is fixedly connected to a cylinder 8, and the piston end of the cylinder 8 is fixedly connected to a lifting block 10, and a rotating shaft 14 is rotatably provided on one side of the lower end face of the lifting block 10, and a plurality of scrapers 15 are fixedly connected to the rotating shaft 14. The pressing plate 5 is provided with a plurality of through grooves 11 matching the size of the scrapers 15, and the scrapers 15 can pass through the through grooves 11, and a support plate 2 is fixedly connected to one side of the upper end face of the pressing plate 5, and the upper end side of the support plate 2 12 is fixedly connected to a cylinder 20, and the piston end of the cylinder 20 is fixedly connected to a connecting block 18, and a triangular box 16 is rotatably provided on one end of the connecting block 18, and a triangular groove 34 matching the specifications of the triangular box 16 is provided on one side of the pressing plate 5, and the triangular box 16 can pass through the triangular groove 34, and a baffle 17 is plugged and slidably connected to one side of the triangular box 16.

[0035] In this embodiment, Figure 2 and Figure 7 As shown, a hydraulic cylinder 2 is fixedly connected to one side of the upper end of the filter press cartridge 1 , and a piston end of the hydraulic cylinder 2 is fixedly connected to one side of the upper end surface of the pressure plate 5 .

[0036] One side of the upper end surface of the lifting block 10 is fixedly connected to a motor 9, and the output end of the motor 9 is fixedly connected to one end of the rotating shaft 14.

[0037] Specifically, in the prior art, the polymer cement waterproof coating raw material is placed on the filter press, and the pressing plate 5 is driven to squeeze the raw material on the filter press, thereby achieving solid-liquid separation of the raw material. However, when the raw material is placed on the filter, it may be in an accumulated state, and the accumulated raw material will form a thicker material layer. The resistance encountered by the liquid when passing through the material layer is increased, which affects the solid-liquid separation efficiency. In addition, the solid raw material will adhere to the surface of the filter and the pressing plate 5 due to being squeezed, making it inconvenient to remove it from the filter and the pressing plate 5, thereby causing the solid raw material to form a layer of barrier on the filter and the pressing plate 5, affecting the subsequent filtration efficiency.

[0038] The scrapers 15 are rotated at the same time to push the raw materials on the filter plate 6 so that the raw materials are spread flat on the surface of the filter plate 6. After the raw materials are spread flat, the scrapers 15 are driven to align with the through grooves 11 and move along the through grooves 11 to above the pressure plate 5. At this time, the hydraulic cylinder 2 can be used to drive the pressure plate 5 to descend to squeeze the raw materials, so that the liquid in the raw materials is discharged and flows out from the drain port 33 through the filter plate 6, thereby realizing solid-liquid separation of the raw materials. Moreover, after the raw materials are spread flat, their thickness is relatively uniform and thin, and the liquid encounters less resistance when passing through the raw material layer, which is conducive to improving the solid-liquid separation efficiency.

[0039] When the liquid passes through the filter plate 6, the pressing plate 5 is driven away from the filter plate 6 until the distance between the upper end surface of the pressing plate 5 and the upper surface of the filter plate 6 is equal to the height of the scraper 15, and then the scraper 15 is driven to pass through the through groove 11 again until the bottom of the scraper 15 is in contact with the upper surface of the filter plate 6, and the upper edge of the scraper 15 is in contact with the lower surface of the pressing plate 5, and then the cylinder 20 is used to drive the triangular box 16 to descend, so that the triangular box 16 passes through the triangular groove 34 and is in contact with the upper surface of the filter plate 6. The area between the two scrapers 15 is regarded as the collection area, and the raw materials are concentrated in the collection area. The edge of one side of the triangular box 16 is driven to coincide with the edge of the collection area, and then the scraper 15 is driven to rotate. The scraper 15 will push the raw materials in the collection area to move until the scraper 15 pushes the raw materials adhering to the upper surface of the filter plate 6 and the lower surface of the pressing plate 5 into the triangular box 16, and then drives the triangular box 16 to rise, so that the rotating scraper 15 can pass under the triangular box 16, and then the triangular box 16 descends again, and repeats the above operation. The raw materials in each collection area will be pushed into the triangular box 16 by different scrapers 15, thereby realizing the removal and collection of the raw materials adhering to the upper surface of the filter plate 6 and the lower surface of the pressing plate 5, avoiding the solid raw materials from being squeezed and adhering to the surface of the filter plate 6 and the pressing plate 5, making it inconvenient to remove them from the filter screen and the pressing plate 5, and thus causing the solid raw materials to form a layer of barrier on the filter screen and the pressing plate 5, affecting the subsequent filtration efficiency.

[0040] In this embodiment, Figure 3-Figure 5 、 Figure 8 As shown, the pressing plate 5 is also provided with a raw material collecting auxiliary component;

[0041] The raw material collection auxiliary component includes a slide rod 25 fixedly connected to the upper end surface of the pressure plate 5, the slide rod 25 is slidably connected to the transverse frame 23, the two ends of the transverse frame 23 are fixedly connected to the slide rod 3 31, the slide rod 3 31 is slidably connected to the push plate 27, and a push block 28 is slidably connected to one side of the push plate 27.

[0042] One end of the transverse frame 23 is threadedly connected to a threaded rod 26, and both ends of the threaded rod 26 are rotatably set on the pressure plate 5. One side of the upper end surface of the pressure plate 5 is fixedly connected to a motor 4 24, and the output end of the motor 4 24 is fixedly connected to one end of the threaded rod 26.

[0043] One end of the push plate 27 is threadedly connected to a threaded rod 32, and both ends of the threaded rod 32 are rotatably set on the transverse frame 23. One end of the transverse frame 23 is fixedly connected to a motor 5 30, and the output end of the motor 5 30 is fixedly connected to one end of the threaded rod 32.

[0044] One side of the push plate 27 is fixedly connected to an electric push rod 29 , and a piston end of the electric push rod 29 is fixedly connected to one side of the push block 28 .

[0045] One end of the baffle 17 is threadedly connected to a threaded rod 1 22 , and both ends of the threaded rod 1 22 are rotatably set on the triangular box 16 . One side of the upper end of the triangular box 16 is fixedly connected to a motor 3 21 , and the output end of the motor 3 21 is fixedly connected to one end of the threaded rod 1 22 .

[0046] One end of the connecting block 18 is fixedly connected to the motor 2 19 , and the output end of the motor 2 19 is fixedly connected to one end of the triangular box 16 .

[0047] A second baffle 35 is fixedly connected to one side of the upper end surface of the pressing plate 5 . When the lower end surface of the triangular box 16 is flush with the upper surface of the pressing plate 5 , the second baffle 35 blocks one side of the triangular box 16 .

[0048] Specifically, in the above embodiment, although the solid raw materials can be collected in the triangular box 16, the storage capacity of the triangular box 16 is limited. To ensure that the triangular box 16 can continuously collect the raw materials, the raw materials therein must be regularly cleaned. Since the raw materials are unevenly distributed in the triangular box 16, it is inconvenient to collect them. In addition, when the raw materials are removed by dumping, the dumping range is large, which is not conducive to collecting them in a receiving container.

[0049] When the material in the triangular box 16 needs to be collected, the motor 3 21 drives the threaded rod 1 22 to rotate, driving the baffle 1 17 to rise, so that the opening on one side of the triangular box 16 is opened, and then the motor 5 30 drives the threaded rod 3 32 to rotate, driving the push plate 27 to move horizontally, so that one end of the push plate 27 is in contact with the side of the baffle 2 35, and at this time the push plate 27 is located at one end of the triangular box 16, and then the motor 4 24 drives the threaded rod 26 to rotate, and the transverse moving frame 23 slides on the slide bar 25, so that the push plate 27 moves to the other end of the triangular box 16, so that the push plate 27 can push the material in the triangular box 16, and at the same time, the push block 28 coincides with the edge of one side of the triangular box 16 and is pushed by the push plate 27 The raw materials will be at the angle between the push plate 27 and the push block 28, and the raw materials will not move out of the triangular box 16 due to the push of the push plate 27. During the movement of the push plate 27, the motor 5 30 drives the threaded rod 32 to rotate, and the push plate 27 moves horizontally, and its end portion always keeps in contact with one side of the baffle 2 35, and the electric push rod 29 drives the push block 28 to move horizontally, so that the push block 28 is always aligned with the edge of one side of the triangular box 16, thereby blocking the raw materials until the raw materials in the triangular box 16 are concentrated at one end inside the triangular box 16. At this time, the receiving container can be placed on one side of the triangular box 16, and the triangular box 16 is rotated by the motor 2 19 to tilt the triangular box 16, so that the raw materials in the triangular box 16 are poured into the receiving container, thereby, under the cooperation of the push plate 27 and the push block 28, the raw materials in the triangular box 16 are concentrated on one side. When the triangular box 16 dumps the raw materials, the dumping range of the raw materials is reduced, and the receiving container is more convenient for receiving the raw materials, which is more convenient.

[0050] Working principle: The raw materials are added through the feeding port 13, and the raw materials fall onto the filter plate 6. The lifting block 10 is driven down by the cylinder 8, so that multiple scrapers 15 pass through the through groove 11 at the same time, and then the hydraulic cylinder 2 is used to drive the pressing plate 5 to descend to the appropriate position. The motor 9 drives the rotating shaft 14 to rotate, and then multiple scrapers 15 rotate at the same time to push the raw materials on the filter plate 6, so that the raw materials are spread flat on the surface of the filter plate 6. When the raw materials are spread flat, the scraper 15 is driven to align with the through groove 11, and the scraper 15 moves along the through groove 11 to the top of the pressing plate 5. At this time, the hydraulic cylinder 2 can be used to drive the pressing plate 5 is squeezed on the raw material in a descending manner, so that the liquid in the raw material is discharged and flows out from the drain port 33 through the filter plate 6, thereby realizing the solid-liquid separation of the raw material. Moreover, after the raw material is spread out, its thickness is relatively uniform and thin, and the resistance encountered by the liquid when passing through the raw material layer is small, which is conducive to improving the solid-liquid separation efficiency. After the liquid passes through the filter plate 6, the pressing plate 5 is driven away from the filter plate 6 until the distance between the upper end surface of the pressing plate 5 and the upper surface of the filter plate 6 is equal to the height of the scraper 15, and then the scraper 15 is driven again to pass through the through groove 11 until the bottom of the scraper 15 is at the same height as the upper surface of the filter plate 6. The upper edge of the scraper 15 is fitted with the lower surface of the pressing plate 5, and then the cylinder 20 is used to drive the triangular box 16 to descend, so that the triangular box 16 passes through the triangular slot 34 and fits the upper surface of the filter plate 6. The area between the two scrapers 15 is regarded as the collection area, and the raw materials are concentrated in the collection area. The edge of one side of the triangular box 16 is driven to coincide with the edge of the collection area, and then the scraper 15 is driven to rotate. The scraper 15 will push the raw materials in the collection area to move until the scraper 15 pushes the raw materials adhered to the upper surface of the filter plate 6 and the lower surface of the pressing plate 5 into the triangular box 16, and then the triangular box 1 is driven to rotate. 6 rises, allowing the rotating scraper 15 to pass under the triangular box 16, and then the triangular box 16 descends again, and the above operation is repeated. The raw materials in each collection area will be pushed into the triangular box 16 by different scrapers 15, thereby realizing the removal and collection of the raw materials adhering to the upper surface of the filter plate 6 and the lower surface of the pressing plate 5, and avoiding the solid raw materials adhering to the surface of the filter plate 6 and the pressing plate 5 due to being squeezed, making it inconvenient to remove them from the filter screen and the pressing plate 5, thereby causing the solid raw materials to form a layer of barrier on the filter screen and the pressing plate 5, affecting the subsequent filtration efficiency;When the lower end surface of the triangular box 16 is flush with the upper end surface of the pressing plate 5, the baffle 25 and the baffle 17 block the two sides of the triangular box 16, and the raw materials will not be scattered onto the pressing plate 5. When the raw materials inside the triangular box 16 need to be collected, the motor 3 21 drives the threaded rod 1 22 to rotate, driving the baffle 17 to rise, so that the opening on one side of the triangular box 16 is opened, and then the motor 5 30 drives the threaded rod 3 32 to rotate to drive the push plate 27 to move horizontally, so that one end of the push plate 27 is in contact with the side of the baffle 2 35, and at this time the push plate 27 is located at one end of the triangular box 16, and then the motor 4 24 drives the threaded rod 26 to rotate, and the transverse moving frame 23 slides on the slide bar 25, so that the push plate 27 moves to the other end of the triangular box 16, so that the push plate 27 can push the raw materials in the triangular box 16. At the same time, the push block 28 coincides with the edge of one side of the triangular box 16, and the raw materials pushed by the push plate 27 will be between the push plate 27 and the At the angle of the push block 28, the raw materials will not be moved out of the triangular box 16 due to the push of the push plate 27. During the movement of the push plate 27, the motor 5 30 drives the threaded rod 3 32 to rotate, and the push plate 27 moves horizontally, and its end portion always keeps in contact with one side of the baffle 2 35. The electric push rod 29 drives the push block 28 to move horizontally, so that the push block 28 is always aligned with the edge of one side of the triangular box 16, thereby blocking the raw materials until the raw materials in the triangular box 16 are concentrated at one end inside the triangular box 16. At this time, the receiving container can be placed on one side of the triangular box 16. The triangular box 16 is rotated by the motor 2 19 to tilt the triangular box 16, and the raw materials in the triangular box 16 are poured into the receiving container. Therefore, under the cooperation of the push plate 27 and the push block 28, the raw materials in the triangular box 16 are concentrated on one side. When the triangular box 16 pours the raw materials, the pouring range of the raw materials is reduced, and the receiving container is more convenient for receiving the raw materials.
