Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a stainless steel perforated mesh filter box with reusable activated carbon. Background Technology

[0002] The process of mineral screening and smelting generates a large amount of wastewater, which needs to be treated to meet discharge standards. Activated carbon, with its excellent adsorption capacity, is widely used in wastewater treatment.

[0003] Activated carbon tanks are typically included in wastewater treatment systems. Their structure consists of an inlet at the top and an outlet at the bottom. A layer of gravel is usually laid at the bottom to facilitate water flow while preventing activated carbon from being discharged through the outlet. The activated carbon layer sits atop the gravel layer. During use, wastewater enters from the top, passes through the activated carbon layer, and exits from the bottom. The activated carbon adsorbs impurities in the wastewater, thus purifying the water. However, after a period of use, a large amount of impurities accumulate on the activated carbon, reducing its purification effect. At this point, the activated carbon layer needs to be cleaned, usually using air-water backwashing. Because activated carbon is lightweight, it is easily washed away by the water flow during backwashing, resulting in activated carbon loss. Furthermore, after prolonged use, deep cleaning or replacement of the activated carbon is necessary. Since the activated carbon layer is a single unit, deep cleaning or replacement requires removing all the activated carbon from the tank, which is not only labor-intensive but also inefficient, impacting wastewater treatment efficiency. Utility Model Content

[0004] To address or partially address the problems existing in the related technologies, this application provides a stainless steel perforated screen filter box that allows for repeated cleaning of activated carbon. This device can prevent the loss of activated carbon during cleaning and improve the convenience of cleaning and replacing activated carbon, thereby ensuring the normal operation of wastewater treatment.

[0005] This application provides a stainless steel perforated screen filter box with reusable activated carbon, comprising:

[0006] The box body has through holes evenly distributed on its side walls;

[0007] The side panel is provided with first slide rails at both the left and right ends of the box body. The side panel is slidably connected to the first slide rails and has through holes evenly opened on the side panel. A boss is also provided on the side panel, and a first mesh plate is installed on the boss, so that a gap is left between the first mesh plate and the side panel to form a cavity.

[0008] The mesh liner is provided with a second slide rail inside the box. The mesh liner is slidably connected to each side of the box through the second slide rail. The mesh liner includes a frame and a second mesh plate. The frame has a square structure and a groove on the side away from the box. The second mesh plate is installed in the groove, so that a gap is left between the second mesh plate and the box 1 to form a cavity.

[0009] Optionally, in some embodiments, a limiting plate is provided at the top of the side plate, and when the limiting plate contacts the box body, both ends of the box body are closed by the side plate.

[0010] Optionally, in some embodiments, a fixing bolt is threadedly connected to the limiting plate, and the housing is provided with threaded holes corresponding to the fixing bolt, so that the side plate can be fixed to the housing by the fixing bolt.

[0011] Optionally, in some embodiments, the second slide rail has a right-angle structure, its installation direction is parallel to the long side of the box, and there are four sets of the second slide rail, which are respectively installed at the four corners of the box. The adjacent second slide rails are symmetrically arranged, so that the second slide rail and the box form a sliding groove, and the mesh liner is slidably connected to the sliding groove.

[0012] Optionally, in some embodiments, the top of the container is provided with a handle, the top of which is parallel to the top surface of the container, thereby facilitating the stacking of the containers in the sewage treatment tank.

[0013] The technical solution provided in this application may include the following beneficial effects:

[0014] This application prevents activated carbon from being lost by placing it inside a tank. When deep cleaning or replacement of activated carbon is required, the tank can be removed from the activated carbon tank in batches to perform deep cleaning or replacement of activated carbon in local areas. This eliminates the need to treat all activated carbon at once, improving the convenience of activated carbon cleaning and replacement, thereby ensuring the normal operation of wastewater treatment.

[0029] See Figure 1-5 A stainless steel perforated screen filter box for repeatedly washing activated carbon, comprising:

[0030] The tank 1 is a hollow, quadrangular prism made of stainless steel. It has evenly spaced through-holes on its side walls. The first through-hole 11, with a diameter of 8-10 cm, is located on the side and top surfaces; the second through-hole 12, with a diameter of 3-5 cm, is located on the bottom surface. In the downflow (sewage flows from top to bottom) activated carbon tank, the larger diameter through-holes on the top and side surfaces of the tank 1 facilitate water flow and prevent clogging, making it suitable for wastewater with high suspended solids. The smaller diameter through-holes on the bottom surface of the tank 1 reduce the outflow velocity of the water, prolonging the contact time between the wastewater and the activated carbon and improving the adsorption effect. Furthermore, the activated carbon content in the tank 1 is 70-80% of its volume. This design facilitates backwashing of the activated carbon with air and water. During backwashing, the activated carbon layer expands under the impact of water and gas; this allowance allows for expansion, ensuring effective cleaning.

[0031] Side plate 2 and box body 1 are both equipped with first slide rails 13. Side plates 2 have sliding grooves 22 on both sides, and are slidably connected to the first slide rails 13 via these grooves. Side plates 2 can seal both ends of box body 1, preventing activated carbon loss. A limiting plate 23 is provided at the top of side plate 2. When the limiting plate 23 contacts box body 1, both ends of box body 1 are sealed by side plate 2. Furthermore, fixing bolts 24 are threaded onto the limiting plate 23, and the box body 1 has threaded holes corresponding to the fixing bolts 24. The fixing bolts 24 can fix side plate 2 to box body 1. To remove side plate 2, remove the fixing bolts 24, and slide side plate 2 off for easy deep cleaning or replacement of activated carbon inside box body 1. Furthermore, third through holes 21 are evenly distributed on side plate 2, with the diameter of the third through holes 21 being the same as the first through holes 11.

[0032] Because the activated carbon particles are small, a boss 25 is provided on the side plate 2 to prevent activated carbon loss. A first mesh plate 26 is fixedly installed on the boss 25 by screws. The first mesh plate 26 has small holes evenly distributed on it. The diameter of the holes is smaller than that of the activated carbon particles, so that a gap is left between the first mesh plate 26 and the side plate 2 to form a cavity 4. When water flows in, it first enters the cavity 4 through the third through hole 21, and then passes through the cavity 4 through the first mesh plate 26 into the tank 1. This design can ensure that the water flow fully contacts the first mesh plate 26 and improve the water intake efficiency.

[0033] Mesh lining 3, a second slide rail 15 is fixedly installed inside the box body 1, see [reference]. Figure 3 The second slide rail 15 has a right-angle structure, and its installation direction is parallel to the long side of the housing 1. There are four sets of second slide rails 15, installed at the four corners of the housing 1, symmetrically arranged between adjacent slide rails 15, thus forming a groove between the second slide rail 15 and the housing. The mesh liner 3 is slidably connected to the groove. By installing corresponding mesh liners 3 inside the housing 1, activated carbon loss is prevented. The mesh liner 3 includes a frame 31 and a second mesh plate 32. (See attached image) Figure 4 The frame 31 has a square structure and is made of stainless steel. A groove is provided on the side away from the box body. The second mesh plate 32 is fixedly installed in the groove by screws, so that a gap is left between the second mesh plate 32 and the box body 1 to form a cavity 4. The principle is the same as that of the first mesh plate 26. This setting can improve the efficiency of water flow into the box body 1.

[0034] In some embodiments, see Figure 6 A handle 14 is fixedly installed on the top of the container 1, with the top of the handle 14 parallel to the top surface of the container 1. This facilitates the stacking of the containers 1 in the wastewater treatment tank. In this embodiment, a multi-layered staggered arrangement is adopted, consisting of three layers from top to bottom. From top to bottom, the activated carbon particles in each layer of the container 1 gradually decrease in size. The larger activated carbon particles in the upper layer are responsible for intercepting suspended solids, while the smaller activated carbon particles in the lower layer are responsible for deep purification of wastewater. Furthermore, the staggered arrangement can alleviate wastewater short-circuiting and improve the adsorption effect of the activated carbon.
