DETAILED DESCRIPTION

[0049] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0050] As Figure 1 and Figure 2 shown, the embodiment of the present application proposes a sewage treatment device, which comprises:

[0051] a box 1,

[0052] a feed inlet 2 fixedly connected to the top of the box 1;

[0053] a filter screen 3 fixedly connected to the inside of the box 1;

[0054] a cleaning device arranged on the top of the filter screen 3 and fixedly connected with the box 1;

[0055] a stirring device arranged between the filter screen 3 and the bottom of the box 1 and fixedly connected with the bottom of the box 1.

[0056] In this embodiment, the housing 1 is made of corrosion-resistant, high-strength materials, such as stainless steel or reinforced polypropylene, to withstand the chemical corrosion and physical impact that may be encountered during wastewater treatment. The housing 1 is designed as a sealed structure, with an opening at the top for installing the inlet 2 and other components, and a drain outlet 11 at the bottom for easy discharge of treated clean water. All interfaces are sealed to prevent wastewater leakage and protect the environment. The inlet 2 is fixedly connected to the top of the housing 1, and its shape is wider at the top and narrower at the bottom to facilitate the introduction of wastewater into the device. The filter screen 3 is fixedly connected inside the housing 1, located below the inlet 2, ensuring that all wastewater entering the housing 1 is filtered first. The filter screen 3 is made of high-strength, corrosion-resistant metal mesh or polymer material mesh, which can effectively intercept solid impurities in the wastewater. Depending on the treatment requirements, different pore sizes can be selected for the filter screen 3 to achieve the best filtration effect. A cleaning device is located on top of the filter screen 3 to periodically clean impurities adhering to the filter screen 3 and prevent clogging. The cleaning device is driven by a motor or controlled by pneumatic pressure and can operate automatically. The stirring device is located between the filter screen 3 and the bottom of the box 1, and is fixedly connected to the bottom of the box 1. Through the stirring action of the stirring device, the sedimentation of suspended solids in the sewage is accelerated, and the uniform distribution of chemical agents (such as coagulants) is promoted, thereby improving the purification effect. The stirring device is driven by a motor or controlled by air pressure, and is equipped with corrosion-resistant stirring blades. The speed is adjustable to meet the needs of different treatment stages.

[0057] The wastewater treatment process includes: wastewater enters the tank 1 through the inlet 2 and is first filtered by the filter screen 3 to remove large impurities; the filtered wastewater is thoroughly mixed with the added chemical agents by the stirring device to promote the sedimentation of suspended solids; as the treatment proceeds, impurities gradually accumulate on the filter screen 3, and the cleaning device is activated periodically to clean the filter screen 3 and keep it unobstructed; the treated clean water is discharged from the drain outlet 11 at the bottom of the tank, completing the entire wastewater treatment process.

[0058] The solution of this utility model can automatically clean the filter screen, reduce the frequency and workload of manual cleaning, and reduce labor costs; it can also achieve timely cleaning of the filter screen, ensure the filtration effect of the filter screen, and improve the sewage treatment efficiency; it can also automatically discharge sewage, ensure the continuous and stable operation of the sewage treatment device, and reduce equipment failure and poor treatment effect caused by untimely manual operation.

[0059] like Figure 2 As shown, in an optional embodiment of the present invention, a drain outlet 4 is provided on the first surface of the housing 1; the bottom edge of the drain outlet 4 is adjacent to the top of the filter screen 3.

[0060] In this embodiment, the first surface of the box 1, i.e. the vertical surface facing the user when the sewage treatment device is in operation, is provided with a sewage outlet 4; when the sewage outlet 4 is opened, the dirt on the top of the filter screen 3 can be removed through the sewage outlet 4, thereby keeping the filter screen 3 clean and unobstructed; by arranging the sewage outlet 4 near the filter screen 3, it can be ensured that the dirt is concentrated and discharged before passing through the filter screen 3, thereby improving the overall filtering efficiency. If too much dirt accumulates in the box 1, it may cause the filter screen 3 to be blocked. Arranging the sewage outlet 4 near the filter screen 3 helps to remove these dirt in time, reducing the risk of blockage.

[0061] As shown in Figure 3 and Figure 4 An optional embodiment of the utility model discloses a cleaning device, which comprises:

[0062] A scraper 5 is arranged on the first surface of the filter screen 3.

[0063] A transmission member is fixedly connected to the first end of the scraper 5.

[0064] A driving member is fixedly connected to the second end of the transmission member.

[0065] A reset member is arranged between the scraper 5 and the box 1, the first end of the reset member is in contact with the scraper 5, and the second end of the reset member is in contact with the box 1.

[0066] A limiting member is fixedly connected to the box 1, the limiting member is slidably connected to the scraper 5, and the scraper 5 reciprocates on the first surface of the filter screen 3 along the direction determined by the limiting member.

[0067] In this embodiment, the cleaning device is used to automatically clean the dust or impurities accumulated on the filter screen 3, ensuring the continuous and efficient operation of the filter screen 3; by controlling the reciprocating motion of the scraper 5 on the surface of the filter screen 3, the cleaning purpose is achieved. Among them, the scraper 5 is directly arranged on the first surface of the filter screen 3, that is, the surface facing the impurities to be cleaned; the material of the scraper 5 needs to be wear-resistant and corrosion-resistant to ensure the stability and cleaning effect during long-term use; the shape and size of the scraper 5 need to be customized according to the specific shape of the filter screen and the cleaning requirements, and are usually designed as long strips or arcs that closely fit the surface of the filter screen 3 to maximize the cleaning area and reduce scratching damage. The transmission component is responsible for transmitting the power of the driving component to the scraper 5, and the first end thereof is fixedly connected with the scraper 5 to ensure direct transmission of power. The driving component can be a motor, a pneumatic cylinder or other devices that can provide continuous or periodic power; the driving component is fixedly connected to the second end of the transmission component to provide a power source for the entire cleaning system; the working state of the driving component can be accurately adjusted by the control system to adapt to different working environments and cleaning requirements. The reset component is arranged between the scraper 5 and the box body 1, and is used to help the scraper 5 return to the initial position after completing a cleaning cycle, preparing for the next cleaning. The first end of the reset component is in contact with the scraper 5, and the second end is fixed to the box body 1. The limiting component is fixedly connected to the box body 1 and forms a sliding connection with the scraper 5, ensuring that the scraper 5 moves reciprocally on a predetermined track, avoiding damage caused by deviation or excessive movement; the limiting component can adopt the form of guide rail, sliding groove, etc., to ensure smooth and efficient cleaning process.

[0068] The working process of the cleaning device includes: when the driving component is started, the scraper 5 is driven to move along the surface of the filter screen 3 by the transmission component to clean the accumulated impurities; when the scraper 5 reaches the end of the stroke, the reset component starts to act to help the scraper 5 return to the initial position stably, and the limiting component ensures the accuracy and safety of the entire movement process. This process is repeated to achieve continuous and automatic cleaning of the filter screen 3.

[0069] As shown in Figure 4 An optional embodiment of the utility model discloses a sealing door 15 is equipped with on the pollution outlet 4, the sealing door 15 is fixedly connected with the scraper 5 through connecting rod 16.

[0070] In this embodiment, the connecting rod 16 is a component connecting the sealing door 15 and the scraper 5; the sealing door 15 and the scraper 5 are fixedly connected through the connecting rod 16, realizing linkage between the two.

[0071] When the need for sewage operation, the sealing door 15 is opened; since the sealing door 15 and the scraper 5 are fixedly connected through the connecting rod 16, when the sealing door 15 is opened, the scraper 5 will also move; in this way, the scraper 5 can clean the accumulated material near the sewage outlet during the sewage process, ensuring smooth and efficient sewage; when the sewage operation is completed, the sealing door 15 is closed, and at the same time the scraper 5 also returns to its initial position through the connecting rod 16, preparing for the next sewage and cleaning operation. Through the linkage of the sealing door and the scraper, the blockage of the sewage outlet can be effectively prevented, the maintenance cost can be reduced, and the service life of the equipment can be prolonged.

[0073] In this embodiment, the main body of the scraper 5 is a plate-shaped body, and the shape and size of the plate-shaped body are usually customized according to application requirements to ensure the best cleaning effect; the protruding part 51 is arranged on the side edge of the scraper 5, the protruding part 51 serves as the connection point between the transmission part and the scraper 5, allowing the transmission part to transmit power to the scraper and drive it to perform the scraping action; in order to ensure the stable movement of the scraper 5, the protruding part 51 can be provided as two, that is, one protruding part 51 is arranged on each side edge of the scraper 5; at the same time, the protruding part 51 can also enhance the strength of the scraper 5 in the connection area, preventing damage due to excessive force during transmission; when the protruding part 51 is sleeved on the outer surface of the limiting part, it also plays a role in limiting the movement range of the scraper 5, ensuring that the scraper 5 moves on the predetermined path. The first end part of the transmission part is fixedly connected with the protruding part 51; the connection mode can be welding, bolt connection, riveting or other mechanical connection modes, which depends on the application requirements and material properties. The limiting part is a component designed to limit the movement range of the scraper 5, and has a smooth outer surface so that the protruding part 51 can be easily sleeved and slide along it; the shape and size of the limiting part match those of the protruding part 51 to ensure tight fit and accurate limiting effect.

[0074] The working principle of the scraper 5 includes: when the transmission part is activated, power is transmitted to the scraper 5 through the protruding part 51 to drive the scraper 5 to move along the outer surface of the limiting part. The sliding of the protruding part 51 on the limiting part ensures the stable movement of the scraper 5 on the predetermined path, and at the same time the limiting part limits the movement range of the scraper 5 to prevent it from exceeding the predetermined cleaning area.

[0075] For example Figure 4As shown, the transmission component is a pull rope 6, the first end of the pull rope 6 is fixedly connected with the protruding part 51, and the second end of the pull rope 6 is fixedly connected with the driving component;

[0076] The limiting component is a sliding rod 7, the first end of the sliding rod 7 is fixedly connected on the first inner surface of the box body 1 through the protruding part 51, and the second end of the sliding rod 7 is fixedly connected on the second inner surface of the box body 1;

[0079] The limiting component is a sliding rod 7, which mainly limits the movement range of the protruding part 51 and prevents it from moving excessively or deviating from the predetermined track; the protruding part 51 has a through hole matched with the diameter of the sliding rod 7, the first end of the sliding rod 7 passes through the protruding part 51 through the through hole and is fixedly connected on the first inner surface of the box body 1, and the connection mode can be welding or bolt connection; the second end of the sliding rod 7 is fixedly connected on the second inner surface of the box body 1, and the connection mode is similar to that of the first end. In this way, the sliding rod 7 forms a stable support and limiting structure, which ensures that the protruding part 51 can only move within the length range of the sliding rod 7; when the protruding part 51 is two, the number of the sliding rod 7 can also be set to two.

[0080] The reset component is a spring 8; the spring 8 is used to restore the protruding part 51 to the initial position; the spring 8 is sleeved on the outer surface of the slide rod 7, so that the stability and position accuracy of the spring 8 can be ensured, and the spring 8 can be prevented from being twisted or deformed when being stressed; the first end of the spring 8 is in contact with the protruding part 51, when the protruding part 51 is pulled by the pull rope 6, the spring 8 will be compressed and store elastic potential energy; and the second end of the spring 8 is in contact with the second inner surface of the box body 1, thereby providing a stable support point; when the pulling force of the pull rope 6 disappears, the spring 8 releases the stored elastic potential energy, and pushes the protruding part 51 to return to the initial position along the slide rod 7; when the slide rod 7 is two, the number of the spring 8 can also be set to two.
