Description

Technical Field

[0001] This utility model relates to the field of deep bed filter technology, specifically to a deep bed filter wall cleaning structure. Background Technology

[0002] Deep bed filters are commonly used for the removal of suspended solids in water treatment. They consist of a single-layer homogeneous filter media or multiple-layer media, and the filter bed is deeper than that of traditional rapid sand filters, often being a downflow gravity filter. The filter media is natural quartz sand, while multi-layer media may use anthracite, quartz sand, and garnet, among others. The particle size of each type of filter media is arranged in descending order of size. With proper hydraulic loading and nitrate volumetric loading design, deep bed filters can also perform denitrification, simultaneously removing suspended solids and nitrates.

[0003] Currently, water treated by the inclined tubes of the sedimentation tank enters the filter through the corridors on both sides of the filter. However, as the wastewater flows through the corridors on both sides of the filter, algae grows on the walls of the deep bed filter. In order to avoid the algae from having an adverse effect on the water treatment, it is necessary to clean it manually every day, which is not only time-consuming and labor-intensive but also inefficient. Therefore, we propose a deep bed filter wall cleaning structure. Utility Model Content

It solves the problem that when sewage flows through the corridors on both sides of the filter tank, moss will grow on the deep bed filter tank wall, which requires daily manual cleaning, which is not only time-consuming and labor-intensive but also inefficient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deep bed filter tank wall cleaning structure, comprising a filter tank body and a toothed ring. Mounting plates are fixedly installed at both ends of the top of the filter tank body. Toothed plates are fixedly installed at the top of the opposite ends of the two mounting plates. Slide rails are fixedly installed at the top of the opposite ends of the two mounting plates. A sliding seat is slidably connected to the outer surface of the slide rail. A fixing frame is fixedly installed on the top of the sliding seat. Fixing blocks are fixedly connected to both ends of the front of the fixing frame. A second cleaning roller is movably connected to the inner surface of the fixing block via bearings. A first cleaning roller and a third cleaning roller are movably connected to both ends of the fixing frame via bearings. A sprocket is fixedly connected to the top of the first, second, and third cleaning rollers. A chain is sleeved on the outer side of the sprocket. A drive motor is fixedly installed at the lower ends of both sides of the fixing frame. A drive gear is fixedly connected to the output end of the drive motor, and the lower end of the drive gear meshes with the toothed plate.

[0006] Preferably, the fixing frame is an n-shaped frame with extension plates on both the upper ends of the left and right sides.

[0007] Preferably, the drive motor is a bidirectional motor that can rotate in both directions.

[0008] Preferably, a first bevel gear is fixedly connected to the upper end of the outer surface of the first cleaning roller, and rotating rods are movably connected to the upper ends of the left and right sides of the fixing frame through bearings. A second bevel gear that meshes with the first bevel gear is fixedly connected to the end of the rotating rod near the first cleaning roller.

[0009] Preferably, a circulating roller and a toothed ring are fixedly connected to the end of the outer surface of the rotating rod away from the second bevel gear, and the upper end of the driving gear meshes with the toothed ring. A circulating groove is opened on the outer surface of the circulating roller, and a movable sleeve is slidably connected to the outer surface of the circulating roller. A guide block adapted to the circulating groove is fixedly connected to the top of the inner side of the movable sleeve.

[0010] Preferably, water-passing seats are fixedly installed at both the left and right ends of the bottom of the fixed frame, and a sealing piston is movably connected to the inner cavity of the water-passing seat. A connecting plate is fixedly connected between one side of the sealing piston and the top of the movable sleeve.

[0011] Preferably, one end of the water inlet seat is connected to a liquid delivery pipe extending into the main channel of the filter tank, and a second one-way valve is installed at the upper end of the liquid delivery pipe. One end of the water inlet seat is connected to a spray pipe, and a first one-way valve is installed at the upper end of the spray pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the setting of the mounting plate and the fixing frame, enables the drive motor to drive the drive gear to rotate, and with the assistance of the meshing toothed plate, the drive motor can drive the fixing frame and the slide to move back and forth on the outer surface of the slide rail. When the drive gear rotates, it can drive the rotating rod and the second bevel gear to rotate through the meshing toothed ring at the upper end. When the second bevel gear rotates, it can drive the first cleaning roller to rotate through the meshing first bevel gear. With the assistance of the top sprocket and chain, the first cleaning roller, the second cleaning roller and the third cleaning roller can rotate simultaneously while the fixing frame moves back and forth, thereby achieving rapid cleaning of the filter pool wall, avoiding manual cleaning, and with high cleaning efficiency.

[0014] 2. This utility model, through the arrangement of the circulating roller and the water-passing seat, can synchronously drive the circulating roller to rotate when the rotating rod rotates. When the circulating roller rotates, it can force the guide rail block to slide in the circulating rail groove, thereby enabling the guide rail block to drive the movable sleeve to move back and forth on the outer surface of the circulating roller. The moving sleeve can drive the sealing piston to move back and forth in the water-passing seat through the connecting plate. When the connecting plate drives the sealing piston to pull outward in the water-passing seat, the infusion pipe, with the cooperation of the second one-way valve, can send the water in the deep bed filter channel into the water-passing seat. When the connecting plate drives the sealing piston to push inward in the water-passing seat, it can force the water in the water-passing seat to be sprayed outward through the first one-way valve and the spray pipe. This can then work with the rotating first cleaning roller, second cleaning roller, and third cleaning roller to clean the pool wall of the deep bed filter, thereby ensuring the cleaning effect of this structure.

[0028] Example 2

[0029] Based on Embodiment 1, this utility model is as follows: Figure 1-Figure 5As shown, a circulating roller 28 and a toothed ring 23 are fixedly connected to the end of the outer surface of the rotating rod 26 away from the second bevel gear 19, and the upper end of the driving gear 12 meshes with the toothed ring 23.

When the circulating roller 28 rotates, it can force the guide rail block 25 to slide in the circulating rail groove 17, thereby allowing the guide rail block 25 to drive the movable sleeve 27 to move back and forth on the outer surface of the circulating roller 28. The reciprocating movable sleeve 27 can drive the sealing piston 6 to move back and forth in the water-passing seat 29 via the connecting plate 24. When the connecting plate 24 drives the sealing piston 6 to move back and forth in the water-passing seat 29... When the water inlet seat 29 is pulled outward, the infusion pipe 20, in cooperation with the second one-way valve 22, can send the water in the deep bed filter channel into the water inlet seat 29. When the connecting plate 24 drives the sealing piston 6 to push the water inlet seat 29 inward, it can force the water in the water inlet seat 29 to be sprayed outward through the first one-way valve 16 and the spray pipe 13. This can then work with the rotating first cleaning roller 8, the second cleaning roller 10, and the third cleaning roller 11 to clean the walls of the deep bed filter, thus ensuring the cleaning effect of this structure.
