Description

Technical Field

[0001] This utility model is a water treatment slag removal device, belonging to the field of water treatment. Background Technology

[0002] In the entire water treatment process, solid waste removal plays a crucial role. It primarily aims to remove various solid impurities from the water, thereby optimizing water quality and laying a solid foundation for subsequent water safety and stable equipment operation. A common solid waste removal method involves installing an inclined filter screen below the drain outlet. When water containing solid impurities flows through this inclined filter screen, larger solid impurities are intercepted. Subsequently, these filtered solid impurities slide down the inclined surface of the filter screen to the outside of the next water treatment container, thus achieving initial solid-liquid separation.

[0003] However, in actual operation, this method has revealed significant drawbacks. Water carrying solid impurities discharged from the drain continuously impacts and wears down the filter screen as these impurities strike it. Once a specific area of ​​the filter screen is damaged by the water flow, current methods often require replacing the entire screen. This results in the undamaged parts of the filter screen not being fully utilized, leading to resource waste and increased water treatment costs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water treatment slag removal device to solve the problems mentioned in the background technology. This utility model realizes that only the area of ​​the filter screen impacted by the water flow needs to be replaced, thereby reducing maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water treatment slag removal device, comprising a frame, a large filter screen installed inside the frame, a support frame on the upper side of the large filter screen, a small filter screen installed inside the support frame, a plurality of evenly arranged perforations on the side of the support frame facing the frame, a column inserted into the perforation, a limiting ring on the lower side of the perforation, the limiting ring being sleeved on the column and connected and fixed to the column, the lower end of the column being connected and fixed to the frame, and a threaded head installed on the upper end of the column, with a nut threadedly connected to the threaded head for limiting the relative position of the column and the support frame.

[0006] Furthermore, a six-sided cylinder is fitted onto the nut and fixed thereto. The upper end of the six-sided cylinder is closed, and a sealing gasket is installed at the lower end of the six-sided cylinder. The sealing gasket is in contact with the support frame.

[0007] Furthermore, a sealing ring is glued to the upper surface of the limiting ring, the sealing ring is sleeved on the column rod, and the sealing ring is in contact with the bottom of the support frame.

[0008] Furthermore, the threaded head and the column are integrally formed, the limiting ring and the column are integrally formed, and the outer diameter of the limiting ring is larger than the inner diameter of the through hole.

[0009] Furthermore, two symmetrical short legs are installed at the end of the frame away from the small filter, and two symmetrically arranged long legs are installed at the end of the frame closer to the small filter.

[0010] Furthermore, a first positioning ear is installed at the lower end of the long support leg, and a second positioning ear is installed at the lower end of the short support leg. Fixing holes are provided on the upper surfaces of the first and second positioning ears.

[0011] Furthermore, two symmetrically arranged side plates are installed on the upper surface of the frame, the side plates are arranged along the length of the large filter screen, and the end of the support frame contacts the side plates.

[0012] The beneficial effects of this utility model are:

[0013] 1. Install a small filter screen in the area below the drain outlet where the large filter screen is located. This allows the water containing solid impurities discharged from the drain outlet to first impact the small filter screen, thus preventing the large filter screen from being directly worn down by the solid impurities in the water flow. When the small filter screen is damaged, only the small filter screen needs to be replaced, without having to replace the large filter screen, thereby reducing maintenance costs.

[0014] 2. After inserting one end of the column rod into the through hole, screw the threaded head into the nut in the six-sided cylinder. Then, make the sealing gasket at the lower end of the six-sided cylinder contact the surface of the support frame. Thus, the connection between the nut and the threaded head is in the closed space formed by the support frame and the six-sided cylinder, preventing the connection between the nut and the threaded head from becoming difficult to separate due to moisture and corrosion.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a water treatment slag removal device, including a frame 1, a large filter screen 2 installed inside the frame 1, two symmetrical short support legs 9 installed at the end of the frame 1 away from the small filter screen 4, and two symmetrically arranged long support legs 7 installed at the end of the frame 1 close to the small filter screen 4. Under the combined action of the long support legs 7 and the short support legs 9, the structure formed by the frame 1 and the large filter screen 2 is in an inclined state, which facilitates solid impurities to slide down along the large filter screen 2. A first positioning ear 8 is installed at the lower end of the long support leg 7, and a second positioning ear 10 is installed at the lower end of the short support leg 9. Fixing holes are opened on the upper surface of the first positioning ear 8 and the upper surface of the second positioning ear 10. Two symmetrically arranged side plates 3 are installed on the upper surface of the frame 1. The side plates 3 are arranged along the length direction of the large filter screen 2. The end of the support frame 5 contacts the side plate 3. Under the restriction of the side plate 3, water flow is prevented from flowing randomly to the side of the frame 1.

[0023] See Figures 1-4A support frame 5 is provided on the upper side of the large filter screen 2. A small filter screen 4 is installed inside the support frame 5. Multiple evenly arranged perforations 17 are opened on the side of the support frame 5 facing the frame 1. A column rod 14 is inserted into the perforation 17. A limiting ring 13 is provided on the lower side of the perforation 17. The limiting ring 13 is sleeved on the column rod 14 and connected and fixed to the column rod 14. The limiting ring 13 and the column rod 14 are integrally formed. The outer diameter of the limiting ring 13 is larger than the inner diameter of the perforation 17. The lower end of the column rod 14 is connected and fixed to the frame 1. A threaded head 11 is installed on the upper end of the column rod 14. The threaded head 11 and the column rod 14 are integrally formed. A nut 16 for limiting the relative position of the column rod 14 and the support frame 5 is threaded on the threaded head 11. In view of the problem that the large filter screen 2 is easily worn by the impact of solid impurities in the water flow, a small filter screen 4 is cleverly set in the key area of ​​the large filter screen 2 below the drain outlet by using a combination structure of support frame 5, column rod 14, nut 16 and other components. When water containing solid impurities is discharged from the drain, the small filter screen 4 absorbs the impact of the water flow first. In this way, the large filter screen 2 avoids direct contact with solid impurities in the water flow, effectively reducing the risk of wear and tear from impact. The advantages of this design are significant: when the small filter screen 4 is damaged due to prolonged impact from water flow and impurities, maintenance personnel only need to replace the small filter screen 4, without needing to replace the large filter screen 2. This improvement not only simplifies the maintenance process but also greatly reduces maintenance costs.

[0024] See 1- Figure 4 A hexagonal cylinder 6 is fitted onto the nut 16 and fixed thereto. The upper end of the hexagonal cylinder 6 is closed, and a sealing gasket 15 is installed at the lower end of the hexagonal cylinder 6. The sealing gasket 15 fits against the support frame 5. A sealing ring 12 is glued to the upper surface of the limiting ring 13. The sealing ring 12 is fitted onto the column rod 14 and fits against the bottom of the support frame 5. First, one end of the column rod 14 is accurately inserted into the through hole 17 on the support frame 5. Then, the end with the threaded head 11 is aligned with the nut 16 inside the hexagonal cylinder 6 and slowly screwed in. As the threaded head 11 is gradually screwed into the nut 16, the operation continues until the sealing gasket 15 at the lower end of the hexagonal cylinder 6 fits tightly against the surface of the support frame 5. At this point, the connection between the nut 16 and the threaded head 11 is cleverly enclosed in the closed space formed by the support frame 5 and the hexagonal cylinder 6. This design effectively prevents the connection between the nut 16 and the threaded head 11 from being directly exposed to the external environment, preventing it from rusting due to moisture. This eliminates the problem of the connection being difficult to disassemble due to rust, and greatly facilitates the maintenance and repair of the device.
