Description

Technical Field

[0001] This utility model relates to the field of aerobic tank technology, specifically to an aerobic tank structure that prevents suspended packing material from floating. Background Technology

[0002] When using high-molecular-weight polyurethane packing in a closed-space aerobic tank, the gas cannot escape from the closed space, causing a large amount of gas to accumulate in the packing and float to the surface. When the packing floats to the outlet, it can easily clog the outlet of the aerobic tank and the maintenance port of the closed water tank. In severe cases, it can cause the water tank to become blocked. Furthermore, the outlet usually needs to be equipped with an interception device to block the packing, which greatly reduces the flow area. When the packing blocks the outlet, a large amount of packing and sewage will overflow through the maintenance port of the closed water tank. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Utility Model Content

[0003] The purpose of this invention is to provide an aerobic tank structure that prevents suspended packing material from floating, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an aerobic tank structure for preventing suspended packing from floating, comprising an aerobic tank body, a maintenance well, an outlet, a hose, a frame interception net, and a stainless steel cover. The maintenance well is located on the upper surface of the aerobic tank body, and a stainless steel cover is provided on the upper surface of the maintenance well. An outlet is located on the inner wall of one side of the aerobic tank body. A frame interception net is vertically installed at the maintenance well, with its lower part extending into the aerobic tank body. A connecting seat is located on one side of the lower part of the frame interception net, and the connecting seat is connected to one end of the hose. The hose communicates with the interior of the frame interception net through the connecting seat. The other end of the hose is connected to the outlet, and a filter plate is installed at the connection between the outlet and the hose.

[0005] Preferably, the aerobic tank structure for preventing suspended packing material from floating provided by this utility model includes a cubic frame interception net with a hollow interior, all six sides of which are densely covered with mesh holes, and the frame interception net is connected to the inner wall of the maintenance well via connectors.

[0006] Preferably, the aerobic pool structure provided by this utility model for preventing suspended packing from floating includes a ladder on the inner wall of the inspection well on the side away from the frame interception net, and the ladder extends into the interior of the aerobic pool.

[0007] Preferably, the present invention provides an aerobic tank structure for preventing suspended packing from floating, wherein the two ends of the hose are respectively fastened to the outlet and the connecting seat through flanges, and the filter plate is clamped between the hose and the flange of the outlet.

[0008] Preferably, in the aerobic tank structure for preventing suspended packing material from floating, the bottom of the frame interception net is at a lower level than the outlet.

[0009] Preferably, the aerobic tank structure provided by this utility model for preventing suspended packing from floating includes a stainless steel cover plate densely covered with through holes.

[0010] Preferably, the aerobic tank structure provided by this utility model for preventing suspended packing from floating includes a surrounding edge on the stainless steel cover plate, which wraps around the outside of the inspection well.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) A frame interception net is vertically installed at the inspection well. The lower part of the frame interception net extends into the aerobic tank. The frame interception net is connected to the outlet through a hose. The polyurethane packing is trapped in the aerobic tank through the frame interception net. The gas in the aerobic tank moves upward through the inside of the frame interception net and is connected to the outside atmosphere through the holes of the stainless steel cover plate. This solves the problem that the air inside the aerobic tank cannot pass through the polyurethane packing, which causes the polyurethane packing to float up and block the outlet. The installation of the frame interception net and hose does not require adjustment of the configuration of other functional pipeline systems. That is, there are no special restrictions on the original pipeline system. The installation is convenient and there is no power consumption problem.

[0013] (2) By connecting the frame interception net with the filter plate, the frame interception net is used for initial screening, which increases the flow area and ensures smooth drainage. This also prevents water from overflowing from the maintenance inlet due to difficulty in drainage.

[0014] (3) A filter plate is also installed at the connection between the hose and the outlet to prevent impurities in the water from being discharged from the outlet. Attached Figure Description

[0022] Please see Figure 1-4 This utility model provides a technical solution: an aerobic tank structure to prevent suspended packing from floating, including an aerobic tank body 1, a maintenance well 2, an outlet 3, a flexible hose 4, a frame intercepting net 5, and a stainless steel cover plate 6. The maintenance well 2 is located on the upper surface of the aerobic tank body 1, and the stainless steel cover plate 6 is located on the upper surface of the maintenance well 2. The stainless steel cover plate 6 is densely covered with through holes 10 to allow air in the aerobic tank body 1 to contact with the outside air. A surrounding edge 11 is provided around the stainless steel cover plate 6, wrapping around the maintenance well 2 to ensure that the stainless steel cover plate 6 can be stably pressed against the maintenance well 2. An outlet 3 is located on one inner wall of the aerobic tank body 1. A frame intercepting net 5 is vertically installed at the maintenance well 2, with the lower part of the frame intercepting net 5 extending into the aerobic tank body 1. The bottom of the frame intercepting net 5 is lower than the level of the outlet 3. The height is designed to ensure that the suspended packing cannot reach the height of the outlet 3, because the air in the aerobic tank 1 comes into contact with the outside air through the frame interception net 5. A ladder 9 is also installed on the inner wall of the inspection well 2 away from the frame interception net 5. The ladder 9 extends into the aerobic tank 1, allowing maintenance personnel to enter the aerobic tank 1. A connecting seat 7 is installed on one side of the lower part of the frame interception net 5. The connecting seat 7 is connected to one end of the hose 4. The hose 4 is connected to the inside of the frame interception net 5 through the connecting seat 7. The other end of the hose 4 is connected to the outlet 3. Both ends of the hose 4 are fastened to the outlet 3 and the connecting seat 7 respectively through flanges. The filter plate 8 is clamped between the flanges of the hose 4 and the outlet 3, so that the hose 4 is connected to the outlet 3 and the filter plate 8 is installed at the same time. The filter plate 8 is installed at the connection between the outlet 3 and the hose 4.

[0023] The frame interception net 5 has a cubic structure and a hollow interior to ensure that water can enter the frame interception net 5 and be discharged from the outlet 3 through the connecting seat 7 and the hose 4. All six sides of the frame interception net 5 are densely covered with mesh holes to prevent suspended filler in the water from entering the frame interception net 5. The frame interception net 1 is made of SUS304 material with a mesh size of 8-10mm. The frame interception net 5 is connected to the inner wall of the inspection well 2 through connectors to realize the installation of the frame interception net 5.

[0024] Installation Method and Operating Principle: Insert the frame interception net 5 into the wellhead of the inspection well 2, and install the frame interception net 5 in the inspection well 2 using the connectors. At this time, the lower part of the frame interception net 5 is located inside the aerobic tank body 1, and the height of the bottom of the frame interception net 5 is lower than the height of the outlet 3. Next, connect the ladder 9 to the inner wall of the inspection well 2 away from the frame interception net 5, and extend the ladder 9 into the aerobic tank body 1. Finally, place the filter plate 8 at the flange of the outlet 3, and connect one end of the hose 4 to the outlet 3 through the flange. At this time, the filter plate 8 is clamped between the outlet 3 and the flange of the hose 4, and the other end of the hose 4 is connected to the connecting seat 7 of the frame interception net 5 through the flange, completing the installation. Before use, pour the polyurethane packing into the aerobic tank. In use, when water enters the aerobic tank, the polyurethane packing is suspended in the water. The water passes through the mesh of the frame interception net 5 and enters the hose 4. When the liquid level exceeds the height of the outlet 3, the water flows out from the outlet 3. Impurities in the water are filtered through the filter plate 8. The polyurethane packing is trapped in the aerobic tank body 1 by the frame interception net 5. The gas in the aerobic tank body 1 moves upward through the inside of the frame interception net 5 and communicates with the outside atmosphere through the holes 10 of the stainless steel cover plate 6. This solves the problem that the air inside the aerobic tank body 1 cannot pass through the polyurethane packing, which causes the polyurethane packing to float and block the outlet 3. It also prevents water from overflowing from the maintenance inlet due to difficulty in drainage. At the same time, impurities in the water are also initially screened by the frame interception net 5 and then discharged from the outlet 3, avoiding poor drainage.

[0026] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
