Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a fiberglass wastewater treatment biochemical tank. Background Technology

[0002] In the field of modern wastewater treatment, fiberglass wastewater treatment biological tanks have good corrosion resistance, high strength, and relatively light weight. The cylindrical structure of fiberglass biological tanks can effectively utilize space and has become one of the commonly used equipment in wastewater treatment processes.

[0003] Most existing fiberglass wastewater treatment biological tanks lack scum removal structures, causing scum to float on the wastewater surface, making collection difficult and hindering the exchange of substances between wastewater and air. The lack of effective guidance and propulsion structures also makes manual scum removal difficult. Regarding sludge treatment, existing equipment also presents challenges in cleaning sludge settled at the bottom of the tank, typically requiring the wastewater to be drained before manual cleaning. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a fiberglass wastewater treatment biochemical tank, comprising a cylindrical reaction tank with an inspection port at the top and an inlet and outlet at the upper end of each end. A scum pusher plate is installed at the upper end of the tank's interior. A guide rod is horizontally fixed to the inner wall of the tank, passing through and slidably connected to the scum pusher plate. Two pusher plate pull ropes are fixed to the top of the scum pusher plate, extending from the inlet and outlet respectively. A sludge storage plate is installed at the bottom of the inner wall of the tank, slidably connected to the tank. Two sets of upper pull ropes are installed at both ends of the sludge storage plate, each set including two sludge plate pull ropes fixed to opposite side walls of the sludge storage plate, extending from the inlet and outlet respectively.

[0005] Furthermore, the bottom shape of the scum pusher plate is adapted to the top shape of the mud storage plate, so that after the mud storage plate is pulled up, the mud can be scraped off the surface of the mud storage plate by pulling the scum pusher plate horizontally.

[0006] Furthermore, the two mud slab ropes are fixed together outside the reaction tank.

[0007] Furthermore, the two outer end faces of the reaction tank are rotatably connected to winding rollers, and two sets of pull ropes are respectively wound around the outer periphery of the two winding rollers. The end face of the winding roller is fixed with a rotating arm, and the rotating arm is fixed with one end of the winding roller near the edge.

[0008] Furthermore, a stabilizing rod is also horizontally fixed to the inner wall of the reaction tank. The stabilizing rod also passes through the scum pusher plate and is slidably connected to the scum pusher plate. The stabilizing rod and the guide rod are symmetrically arranged relative to the scum pusher plate.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. Operators only need to pull the push plate and rope to push the scum until it accumulates at the inlet or outlet, and then the scum can be removed from the inlet or outlet. Compared with traditional manual scum removal methods, this improves the efficiency of scum removal. At the same time, timely removal of scum ensures good material exchange between wastewater and air, which is conducive to biochemical reactions, improves wastewater treatment effect, and reduces bacterial growth and odor emission.

[0011] 2. Sludge removal does not require emptying the wastewater from the tank. Simply rotate the crank to raise the sludge storage plate, and then pull the pusher rope to scrape up and collect the sludge via the scum pusher. This improves the convenience of sludge removal, ensures timely removal of sludge from the bottom of the tank, and maintains the effective volume of the biological treatment tank.

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] A fiberglass wastewater treatment biochemical tank, such as Figure 1 and Figure 2 As shown, the reaction tank includes a cylindrical reaction tank 1. An inspection port 101 is provided at the top of the reaction tank 1. An inlet 102 and an outlet 103 are provided at the upper end of the two end faces of the reaction tank 1. A scum pusher plate 2 is provided at the upper end of the interior of the reaction tank 1. A guide rod 3 is horizontally fixed to the inner wall of the reaction tank 1. The guide rod 3 passes through the scum pusher plate 2 and is slidably connected to the scum pusher plate 2. A stabilizing rod 4 is also horizontally fixed to the inner wall of the reaction tank 1. The stabilizing rod 4 also passes through the scum pusher plate 2 and is slidably connected to the scum pusher plate 2. The stabilizing rod 4 and the guide rod 3 are symmetrically arranged relative to the scum pusher plate 2. Two pusher pull ropes 5 are fixed to the top of the scum pusher plate 2. The two pusher pull ropes 5 extend from the inlet 102 and the outlet 103, respectively.

[0019] The scum pusher plate 2, together with the guide rod 3, the stabilizing rod 4 and the pusher plate pull rope 5, provides a stable sliding track for the scum pusher plate 2. When the operator pulls the pusher plate pull rope 5, the scum pusher plate 2 can be driven to move, and the scum on the water surface can be efficiently pushed to the feed inlet 102 or the discharge outlet 103 for collection, simplifying the scum cleaning process.

[0020] like Figure 1 As shown, in this embodiment, a sludge storage plate 6 is provided at the bottom of the inner wall of the reaction tank 1. The sludge storage plate 6 is slidably connected to the reaction tank 1. Two sets of pull ropes are provided at both ends of the sludge storage plate 6. Each set of pull ropes includes two mud plate pull ropes 7 fixed to the two opposite side walls of the sludge storage plate 6. The two sets of pull ropes extend from the feed inlet 102 and the discharge outlet 103, respectively. The bottom shape of the scum pusher 2 is adapted to the top shape of the sludge storage plate 6. After the sludge storage plate 6 is pulled up, the sludge can be scraped off the surface of the sludge storage plate 6 by pulling the scum pusher 2 horizontally. The two mud plate pull ropes 7 are fixed to one outside the reaction tank 1. The two outer end faces of the reaction tank 1 are rotatably connected to the winding rollers 8. The two sets of pull ropes are respectively wound around the outer periphery of the two winding rollers 8. The end face of the winding roller 8 is fixed with a rotating arm 9. The rotating arm 9 is fixed to one end of the end face of the winding roller 8 near the edge.

[0021] Among them, rotating the rotating blade 9 drives the winding roller 8 to wind the mud plate pull rope 7, thereby pulling up the mud storage plate 6 to collect the sludge at the bottom of the tank; the shape of the scum pusher 2 is adapted to the mud storage plate 6. After pulling up the mud storage plate 6, the horizontal pulling of the scum pusher 2 can scrape up the sludge and push it to the feed inlet 102 or the discharge outlet 103, so as to realize convenient sludge cleaning and reduce the impact of sludge deposition on the biological treatment tank.

[0022] The working principle of this utility model is as follows:

[0023] When scum removal is required, the operator pulls the pusher rope 5 at the feed inlet 102 or discharge outlet 103. The pulling force is transmitted to the scum pusher plate 2 through the pusher rope 5. The guide rod 3 and the stabilizing rod 4 are symmetrically arranged on the inner wall of the reaction tank 1 and are slidably connected to the scum pusher plate 2, restricting the movement direction of the scum pusher plate 2. The scum pusher plate 2 moves along the axial direction of the guide rod 3 and the stabilizing rod 4, effectively preventing deviation or jamming during the pulling process. The scum pusher plate 2 contacts the scum on the water surface, pushing the scum until it accumulates at the feed inlet 102 or discharge outlet 103, where it can be scooped out.

[0024] To facilitate the removal of sludge settled at the bottom of reaction tank 1, a sludge storage plate 6 is provided. After the sludge settles, it adheres to the sludge storage plate 6. When cleaning the sludge on the sludge storage plate 6, the rotating handles 9 at both ends are rotated simultaneously, and the winding roller 8 winds the sludge plate pull rope 7, so that the sludge storage plate 6 is gradually pulled up. After the sludge storage plate 6 is pulled up to contact the bottom of the scum pusher plate 2, the sludge is scraped off the surface of the sludge storage plate 6 by pulling the scum pusher plate 2 horizontally, so that the sludge is gradually pushed to the feed inlet 102 and the discharge outlet 103 along with the scum pusher plate 2. The sludge can then be scooped out at the feed inlet 102 or the discharge outlet 103.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
