Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sedimentation tank for wastewater treatment that is easy to clean. Background Technology

[0002] Urban sewage contains a certain amount of inorganic particulate impurities such as mud, sand, and coal ash. To prevent these impurities from interfering with the operation of biological treatment and sludge treatment systems, a grit chamber is required before secondary sewage treatment. During sewage treatment, the presence of mud and sand in the sewage will affect the treatment efficiency of subsequent equipment. If left untreated, the sediment will accumulate in the tank, thus requiring a grit chamber to protect the downstream water treatment equipment.

[0003] Currently, sludge removal in sedimentation tanks is mainly carried out using two methods: sludge removal machines and mud pumps. Sludge removal machines require specialized equipment and operators, increasing sludge removal costs. Mud pump sludge removal, on the other hand, removes sludge by pumping out mud, requiring constant adjustment of the mud pump's position, resulting in poor cleaning effect, low work efficiency, and the extraction of water from the sedimentation tank, leading to significant water loss. Utility Model Content

It has a simple structure and adopts a distributed structure, which facilitates the sequential discharge of sludge and sediment from different locations in the sedimentation tank. It also facilitates the loading of sediment onto trucks, thereby reducing dredging costs and minimizing water loss in the sedimentation tank. It is efficient, easy to use, and can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sedimentation tank for sewage treatment that is easy to clean, comprising a sedimentation tank, wherein the bottom of the sedimentation tank is provided with uniformly distributed funnels, the bottom of the funnels is provided with a discharge pipe, and the upper end and the lower end of the side of the discharge pipe are provided with a slide valve, wherein the valve seat of the slide valve is provided with a sealing push plate, and the sealing push plate can slide along the inner side of the valve seat.

[0006] As a preferred technical solution of this utility model, the valve seat is opened at one end away from the slide gate valve drive motor, and a sealing shell is fitted at the open end of the valve seat. The sealing shell is provided with an elastic connecting member that is connected to the sealing push plate.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: a sedimentation tank for sewage treatment that facilitates sludge removal, comprising a sedimentation tank 1, with evenly distributed funnels 2 at the bottom of the sedimentation tank 1, and a discharge pipe 3 at the bottom of the funnels 2. Both the upper and lower ends of the side of the discharge pipe 3 are equipped with slide valves. A sealing push plate 53 is provided inside the valve seat 4 of the slide valve, and the sealing push plate 53 can slide along the inner side of the valve seat 4. Initially, the slide valve on the upper side of the discharge pipe 3 is open, and the slide valve on the lower side is closed. Sediment in the sedimentation tank 1 falls into the discharge pipe 3 through the funnels 2. A transfer vehicle is moved to the lower side of the corresponding discharge pipe 3, the upper slide valve is closed, and the lower slide valve is opened, thereby removing the sludge from the discharge pipe 3.

[0019] Furthermore, the valve seat 4 is open at one end away from the slide gate valve drive motor, and a sealing shell 5 is fitted onto the open end of the valve seat 4. The sealing shell 5 has an elastic connector that connects to the sealing push plate 53 inside.

[0020] Furthermore, the elastic connector includes a sealing plug 51 installed on the inner wall of the sealing shell 5. The sealing plug 51 is movably engaged with the open end of the valve seat 4. The side of the sealing plug 51 is evenly provided with elastic elements 52 connected to the sealing push plate 53. When the upper slide valve is closed, sediment will be trapped in the groove on the side of the valve seat 4. During the closing process of the slide, the front end of the slide pushes the sediment into the groove, and the sediment pushes the sealing push plate 53 to squeeze the elastic elements 52. When the upper slide is opened, the elastic elements 52 recover and push the sediment out through the sealing push plate 53, thereby ensuring the sealing effect of the upper slide valve.

[0021] Furthermore, a positioning groove 41 is provided on the upper surface of the valve seat 4, and a positioning hole 6 corresponding to the positioning groove 41 is provided on the upper surface of the sealing shell 5. The positioning pin is inserted into the positioning hole 6 and the positioning groove 41 to fix the valve seat 4.

[0022] Furthermore, the inner wall of the sedimentation tank 1 is provided with evenly distributed guide plates 21 to guide the sediment into the funnel 2.

[0023] The slide gate valve used in this utility model is an electric slide gate valve. This utility model improves the valve seat 4 of the electric slide gate valve. The structure of other parts of the electric slide gate valve will not be described in detail here.

[0024] When using:

[0025] In the initial state, the slide valve on the upper side of the discharge pipe 3 is in the open state, and the slide valve on the lower side is in the closed state.

[0026] The sediment in sedimentation tank 1 falls through funnel 2 into discharge pipe 3;

[0027] Then move the transfer vehicle to the lower side of the corresponding discharge pipe 3, close the upper gate valve, and open the lower gate valve to remove the sludge from the discharge pipe 3.

[0028] When the upper slide valve is closed, sediment will be stuck in the groove on the side of the valve seat 4. During the closing process of the slide valve, the front end of the slide valve pushes the sediment into the groove, and the sediment pushes the sealing push plate 53 to squeeze the elastic element 52.

[0029] When the upper slide plate is opened, the elastic element 52 returns to its original state and pushes out the sediment through the sealing push plate 53, thereby ensuring the sealing effect of the upper slide plate valve.

[0030] This utility model has a simple structure and adopts a distributed structure, which facilitates the sequential discharge of sludge and sediment from different locations in sedimentation tank 1, and facilitates the loading of sediment onto trucks, thereby reducing dredging costs, minimizing water loss from the sedimentation tank, improving work efficiency, and making it easy to use.

Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
