Description

Technical Field

[0001] This utility model relates to the field of filter bed cleaning technology, and more specifically, to a small-scale automatic sand replenishment device for filter beds. Background Technology

[0002] Filter beds are a common type of filtration device in water treatment. They can remove suspended solids from water to obtain water with lower turbidity. Filter beds often use granular materials such as gravel as filler, which allows wastewater to come into contact with the microbial film growing on the surface of the filler, thus purifying the wastewater. After a period of use, the filler in the filter bed is cleaned by backwashing.

[0003] When backwashing the packing material in the filter bed, the water flow usually sprays out from below the packing material, causing the gravel and other packing materials to be washed up and flow. During the washing process, the gravel will flow into the drainage pipe with the water flow, thereby reducing the amount of gravel in the filter bed and affecting the subsequent filtration effect of the filter bed. Utility Model Content

[0004] The purpose of this invention is to provide a small-scale automatic sand replenishment device for filter beds, which can prevent the loss of packing material and re-add it to the filter bed during cleaning.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a small automatic sand replenishment device for a filter pool, including a filter pool, a partition plate fixedly installed inside the filter pool, a support plate fixedly installed at the top of the filter pool, a toothed rack provided on the inner wall of the filter pool, a lifting component provided inside the filter pool, stirring components provided on both sides of the lifting component, and a cleaning component provided at the top of the lifting component. The lifting assembly includes a support frame, a mounting base is fixedly installed on the top surface of the support frame, a lever is fixedly installed on one side of the support frame, a fixing block is fixedly installed at the top of the support frame, and the output end of an electric push rod is fixedly installed on the top surface of the fixing block.

[0006] Furthermore, one end of the electric push rod is fixedly connected to the support plate, and the support frame is slidably connected to the partition plate through a groove opened inside it.

[0007] Furthermore, a filter plate is fixedly installed on one side of the fixing block, and the filter plate has a triangular cross-section.

[0008] Furthermore, the cleaning assembly includes a connecting rod, both ends of which are fixedly connected to a support plate, and a hinge seat is fixedly installed on the bottom surface of the connecting rod.

[0009] Furthermore, a support rod is hinged to one side of the hinge seat, and a rotating rod is rotatably mounted on the support rod through a through hole at its other end. A fixing sleeve is fixedly mounted on the outer wall of the rotating rod.

[0010] Furthermore, a spring is fixedly installed on one side of the support rod, and two sets of springs are symmetrically arranged on the support rod with the springs located between the support rods.

[0011] Furthermore, the stirring assembly includes a mounting rod, on the outer wall of which a stirring rod is fixedly mounted, and the mounting rod is rotatably connected to the mounting base through a through hole.

[0012] Furthermore, a gear is fixedly mounted on one end of the mounting rod, one side of the gear meshes with a rack, and a second baffle is rotatably mounted on one end of the mounting rod.

[0013] Furthermore, one side of the second baffle is fixedly connected to the support frame, and a first baffle is fixedly installed on one side of the second baffle. The first baffle is slidably connected to it through a groove opened in the inner wall of the filter tank.

[0014] Furthermore, a brush is fixedly installed at one end of the first baffle, and the brush is in contact with the rack; a water spray pipe is fixedly installed on one side of the second baffle.

[0015] Compared to existing technologies, the advantages of this solution are as follows: 1. This solution incorporates lifting and cleaning components. This design prevents the filter media from falling into the drainage channels between the baffles and being flushed away with the water flow during backwashing. Simultaneously, during the lifting of the support frame, the water flow in the filter tank is amplified by the toggle plate, thereby improving the cleaning efficiency of the filter media. Furthermore, as the filter plate moves upward, the filter media on the surface of the filter plate can be pushed back into the filter tank through the fixing sleeve, thus completing automatic sand replenishment.

[0016] 2. This solution incorporates a stirring assembly. This design enables the stirring rod to rotate during the movement of the support frame, thereby improving the efficiency of backwashing the packing and reducing cleaning time. Simultaneously, the second and first baffles protect the gears, preventing the packing from affecting the meshing of the gears and rack. Furthermore, the brush and water spray pipe further ensure that the packing no longer affects the gears and rack. Attached Figure Description

[0019] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not intended to limit the scope of protection of this utility model. Example 1

[0020] A small-scale automatic sand replenishment device for filter beds, such as Figure 1-5 As shown, the filter includes a filter tank 1, a baffle 7 is fixedly installed inside the filter tank 1, a support plate 5 is fixedly installed at the top of the filter tank 1, a toothed rack 2 is provided on the inner wall of the filter tank 1, a lifting component 6 is provided inside the filter tank 1, a stirring component 3 is provided on both sides of the lifting component 6, and a cleaning component 4 is provided at the top of the lifting component 6. The lifting component 6 includes a support frame 64, a mounting base 65 fixedly installed on the top surface of the support frame 64, a lever plate 66 fixedly installed on one side of the support frame 64, a fixing block 62 fixedly installed at the top of the support frame 64, an output end of an electric push rod 61 fixedly installed on the top surface of the fixing block 62, one end of the electric push rod 61 fixedly connected to the support plate 5, the support frame 64 slidably connected to the partition plate 7 through a groove opened therein, and a filter plate 63 fixedly installed on one side of the fixing block 62, the filter plate 63 having a triangular cross-section. In practical applications, by setting up the lifting component 6, during the backwashing process of the packing in the filter tank 1, the packing flows into the drainage channel between the baffles 7 with the water flow. At the same time, since the filter plate 63 is located between the baffles 7, the packing stays on the surface of the filter plate 63. Then, the electric push rod 61 is activated to drive the support frame 64 to move upward, thereby driving the filter plate 63 to move upward gradually. During the upward movement of the support frame 64, the packing in the filter tank 1 can be moved by the deflector plate 66, thereby improving the cleaning effect of the packing. Example 2

[0021] A small-scale automatic sand replenishment device for filter beds, which differs from embodiments 1 and 3 in that, as Figure 5 As shown, the cleaning component 4 includes a connecting rod 43, both ends of which are fixedly connected to the support plate 5. A hinge seat 42 is fixedly installed on the bottom surface of the connecting rod 43. A support rod 44 is hinged to one side of the hinge seat 42. A rotating rod 45 is rotatably installed on the support rod 44 through a through hole at its other end. A fixing sleeve 46 is fixedly installed on the outer wall of the rotating rod 45. A spring 41 is fixedly installed on one side of the support rod 44. Two sets of support rods 44 are symmetrically arranged, and the springs 41 are located between the support rods 44.

[0022] In practical applications, by setting up a cleaning component 4, when the filter plate 63 moves upward, the top surface of the filter plate 63 will contact the fixing sleeve 46. At the same time, since the top surface of the filter plate 63 is inclined, when the filter plate 63 continues to move upward, the fixing sleeve 46 will move to both sides along the surface of the filter plate 63 and stretch the spring 41, thereby pushing the packing material on the surface of the filter plate 63 back into the filter tank 1 through the fixing sleeve 46. Example 3

[0023] A small-scale automatic sand replenishment device for filter beds, which differs from Embodiment 1 in that, as Figure 4 As shown, the stirring assembly 3 includes a mounting rod 37, on the outer wall of which a stirring rod 36 is fixedly mounted. The mounting rod 37 is rotatably connected to the stirring rod 36 through a through hole in the mounting base 65. A gear 31 is fixedly mounted at one end of the mounting rod 37, and one side of the gear 31 meshes with a rack 2. A second baffle 33 is rotatably mounted at one end of the mounting rod 37, and one side of the second baffle 33 is fixedly connected to a support frame 64. A first baffle 32 is fixedly mounted on one side of the second baffle 33, and the first baffle 32 is slidably connected to the filter tank 1 through a groove in the inner wall of the filter tank 1. A brush 34 is fixedly mounted at one end of the first baffle 32, and the brush 34 contacts the rack 2. A water spray pipe 35 is fixedly mounted on one side of the second baffle 33.

[0024] In practical applications, by incorporating a stirring assembly 3, the support frame 64 moves up and down as the electric push rod 61 drives it. This movement of the support frame 64, in turn, moves the mounting rod 37, which in turn rotates the gear 31 via the rack 2. This rotation of the mounting rod 37, in turn, rotates the stirring rod 36, stirring the packing material in the filter tank 1 and accelerating its cleaning efficiency. Furthermore, the movement of the support frame 64 also moves the first baffle 32 and the second baffle 33, which block the packing material, preventing it from entering the meshing position of the gear 31 and rack 2. Simultaneously, the movement of the support frame 64 cleans the surface of the rack 2, preventing the packing material from getting stuck. Additionally, the water spray pipe 35 sprays water into the second baffle 33, causing the packing material to move outwards, further preventing it from affecting the meshing of the gear 31 and rack 2.

[0025] Working principle: During the backwashing process of the packing material in filter tank 1, the packing material flows into the drainage channel between the baffles 7 with the water flow. Since filter plate 63 is located between the baffles 7, the packing material remains on the surface of filter plate 63. Then, the electric push rod 61 is activated, driving the support frame 64 upward, thereby gradually moving the filter plate 63 upward. During the upward movement of the support frame 64, the push plate 66 can move the packing material in filter tank 1, thereby improving the cleaning effect of the packing material. When the filter plate 63 moves upward, the top surface of the filter plate 63 contacts the fixing sleeve 46. Since the top surface of the filter plate 63 is inclined, as the filter plate 63 continues to move upward, the fixing sleeve 46 moves to both sides along the surface of the filter plate 63, stretching the spring 41. This pushes the packing material on the surface of the filter plate 63 back into filter tank 1 through the fixing sleeve 46. The electric push rod 61 drives the support frame 64 upward. During the up-and-down movement of the support frame 64, the support frame 64 can drive the mounting rod 37 to move, so that the mounting rod 37 can drive the gear 31 to rotate through the rack 2, thereby driving the agitator 36 to rotate and agitate the packing in the filter tank 1, accelerating the cleaning efficiency of the packing. During the movement of the support frame 64, the first baffle 32 and the second baffle 33 can also move, thereby blocking the packing and preventing it from entering the meshing position of the gear 31 and the rack 2. At the same time, during the movement, the brush 34 can clean the surface of the rack 2 to prevent the packing from getting stuck in the rack 2. Water can also be sprayed into the second baffle 33 through the water spray pipe 35, thereby driving the packing to move outward and further preventing the packing from affecting the meshing of the gear 31 and the rack 2.

[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
