Description

Technical Field

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

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] As disclosed in CN214192632U, a wastewater treatment tank for a wastewater treatment device includes a main body, a connecting pipe connected to the outside of the main body, a support mechanism on the outside of the main body, a top cover fixed to the top of the main body, a connecting shell on the top of the top cover, and a stabilizing mechanism connected to the bottom of the main body. The support mechanism allows for support and fixation of the bottom of the connecting pipe on the outside of the main body, preventing deformation of the connecting pipe and reducing maintenance frequency. The stabilizing mechanism facilitates the fixing of the main body to the anti-slip sleeve, and increases friction at the contact points when the main body is placed on the ground, improving stability.

[0004] Although the aforementioned patents can improve the stability of wastewater treatment tanks during placement by using support and stabilizing mechanisms, most wastewater treatment tanks on the market do not have solid-liquid separation capabilities. This can lead to the deposition and accumulation of solid pollutants in pipes and equipment during long-term use, causing blockages. This not only affects the normal operation of wastewater treatment but may also lead to equipment damage and increased maintenance costs. Utility Model Content

To better understand the technical content of the present utility model, specific embodiments are provided and described in conjunction with the accompanying drawings. Various aspects of the present utility model are described in this disclosure with reference to the accompanying drawings, which show many illustrative embodiments. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] As attached Figure 1 To be continued Figure 4 As shown: This embodiment provides a sewage treatment tank for sewage treatment equipment, including a tank body 1, a sealing cover 3 on the top of the tank body 1, the tank body 1 and the sealing cover 3 being adapted to each other, and a separation structure 2 being provided in the inner cavity of the tank body 1.

[0022] The separation structure 2 includes a protective box 29 fixedly connected to the sealing cover 3. A motor 21 is embedded in one side of the inner cavity of the protective box 29. An eccentric wheel 22 is fixedly connected to the output shaft of the motor 21. A rotating block 23 is rotatably connected to the surface of the eccentric wheel 22. A transmission plate 24 is rotatably connected to the inner cavity of the rotating block 23. A support rod 210 is rotatably connected to the surface of the transmission plate 24. Both ends of the support rod 210 are rotatably connected to the protective box 29. Connecting plates 25 are rotatably connected to both sides of the transmission plate 24. A fixing block 26 is rotatably connected to the opposite side of the two connecting plates 25. A transmission rod 27 is fixedly connected to the bottom of the fixing block 26. The bottom end of the transmission rod 27 extends through to the bottom of the sealing cover 3 and is located in the inner cavity of the tank body 1. A filter screen 28 is fixedly connected to the bottom end of the transmission rod 27. The top of the filter screen 28 has an inclined surface.

[0023] Specifically, the surface of the filter screen 28 is fixedly connected with three guide blocks 212 arranged in a ring, and the inner cavity of the tank body 1 is provided with a limiting groove 211 that matches the guide blocks 212.

[0024] In this embodiment, the guide block 212 and the guide groove 211 work together to guide and limit the movement of the filter screen 28, ensuring the stability of the filter screen 28 during movement.

[0025] Specifically, the surface of the tank 1 is connected to the sewage inlet pipe 4 and the solid impurity outlet pipe 5, respectively, and the highest position of the filter screen 28 is located at the lowest point of the inner cavity of the solid impurity outlet pipe 5.

[0026] In this embodiment: by using the sewage inlet pipe 4 and the solid impurity outlet pipe 5 together, firstly, the sewage inlet pipe 4 improves the channel for external sewage to enter the inner cavity of the tank 1, and the solid impurity outlet pipe 5 provides a channel for the impurities screened out by the top of the filter screen 28 to be discharged.

[0027] Specifically, the top of the protective box 29 is fixedly connected to a mounting plate 213, the surface of the mounting plate 213 is provided with ventilation holes, and the inner cavity of the ventilation holes is fixedly connected with a dustproof net.

[0028] In this embodiment, the mounting plate 213, the vent, and the dustproof net work together to seal the protective box 29. The vent and the dustproof net provide a channel for the exchange of external air with the air inside the protective box 29, and to a certain extent, prevent external debris from entering the inner cavity of the protective box 29.

[0029] Specifically, the surface of the transmission rod 27 is fixedly connected to two symmetrically arranged limiting plates 214, and the surface of the sealing cover 3 is provided with a limiting groove that matches the limiting plates 214.

[0030] In this embodiment, the use of the limiting plate 214 and the limiting groove together guides and limits the transmission rod 27, further ensuring the movement trajectory of the transmission rod 27.

[0031] The working principle and usage process of this utility model are as follows: The user introduces sewage into the inner cavity of the tank 1 through the sewage inlet pipe 4, turns on the motor 21, and the output shaft of the motor 21 drives the eccentric wheel 22 to rotate. Due to the shape of the eccentric wheel 22, the rotating block 23 rotates around the eccentric wheel 22 as the axis, and the rotating block 23 drives the transmission plate 24 to swing around the support rod 210 as the axis. The transmission plate 24 drives the fixed block 26 to move up and down through the connecting plate 25. The fixed block 26 drives the filter screen 28 to move up and down through the transmission rod 27, so that the filter screen 28 filters and screens the solid impurities in the sewage when it moves, so that the solid impurities remain on the surface of the filter screen 28, and the liquid flows to the bottom of the inner cavity of the tank 1. When the filter screen 28 rises to the position of the solid impurity outlet pipe 5, the solid impurities are discharged from the inner cavity of the solid impurity outlet pipe 5 because the surface of the filter screen 28 is set with an incline, thereby completing the purpose of separating the solid impurities in the sewage from the water.

[0032] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0033] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
