[0003] In traditional sewage treatment equipment, filtration is a crucial step in achieving initial sewage purification. Most equipment utilizes fixed filter components, such as screens and filter plates, to intercept and filter solid impurities in sewage. However, in actual operation, the large number of suspended particles, colloids, and other impurities in sewage easily adhere to and accumulate in the filter holes, causing them to become clogged. Once the filter holes become clogged, not only does the sewage filtration rate drop significantly, reducing the equipment's treatment efficiency, but it also increases filtration pressure, increases energy consumption, and can even cause equipment failure and shorten its service life.

[0018] The present invention provides a multi-stage purification treatment device for sewage treatment for environmental management. It has the following beneficial effects:

[0019] 1. The multi-stage purification treatment equipment for sewage treatment of this environmental governance is provided with a filtering mechanism. When sewage enters the filtering mechanism, the motor is started and the liquid inlet barrel is driven to rotate in the slide groove of the annular block through the transmission shaft. When the liquid inlet barrel rotates, due to the action of centrifugal force, impurities are thrown to the cylinder wall, and the filter holes perform preliminary filtration on larger particles of impurities in the sewage. The filtered sewage enters the annular liquid guide groove on the inner wall of the liquid inlet barrel. The annular liquid guide groove guides the liquid flow so that the sewage is evenly distributed and flows out through the filter holes. The filtering mechanism uses the rotating liquid inlet barrel in conjunction with the filter holes to achieve preliminary filtration of larger particles of impurities in the sewage. Compared with traditional static filtration, dynamic filtration can improve filtration efficiency and avoid accumulation and clogging of impurities at a fixed position.

[0020] Second, the multi-stage sewage treatment equipment used in this environmental governance project is equipped with a scraping mechanism. The clamping plate is fixed to the clamping groove of the annular block, and the liquid inlet barrel rotates within the receiving groove. The scraper blade of the scraping unit is in close contact with the inner wall of the liquid inlet barrel, scraping off impurities attached to the inner wall. The brush disc of the cleaning unit cleans the annular liquid guide groove under the action of the spring. The scraped impurities fall into the collection hopper, and the remaining impurities are drained through the leakage hole after the liquid is drained. The scraping mechanism continuously cleans impurities from the inner wall of the liquid inlet barrel and the annular liquid guide groove, preventing the filter holes from clogging, ensuring the long-term and efficient operation of the filter mechanism, reducing the frequency of manual cleaning, lowering maintenance costs, and preventing the accumulation of impurities that affect the sewage treatment effect.

[0021] 3. The multi-stage purification treatment equipment for sewage treatment of the environmental governance uses a liquid separation mechanism. The sewage after preliminary filtration flows downward to the liquid separation mechanism. After the sewage hits the liquid baffle plate, it is dispersed under the obstruction of its closed upper end and flows evenly to the adsorption layer below through the liquid separation holes on the surface of the liquid baffle plate.

[0022] The liquid separation mechanism disperses the sewage evenly, avoiding excessive or insufficient local flow, ensuring that the adsorption layer can evenly contact the sewage, giving full play to the adsorption effect, improving the degree of sewage purification, and ensuring the stability and efficiency of the overall sewage treatment effect.

[0023] Fourth, this multi-stage sewage treatment equipment for environmental governance utilizes an adsorption layer. The sewage, evenly flowing through the liquid separation mechanism, comes into contact with the adsorption layer. The adsorption material within the layer absorbs any remaining impurities, harmful substances, and odors. The adsorption layer deeply purifies the initially filtered sewage, effectively removing any remaining pollutants, improving water quality, and enhancing the equipment's adaptability and treatment capabilities for sewage of varying degrees of contamination.

[0024] Fifth, this multi-stage sewage treatment equipment for environmental governance uses a filter outlet mechanism. Motor 2 drives drive shaft 2, causing the liquid storage barrel to rotate counterclockwise. Purified water enters the barrel through an inclined hole on its surface. Spiral blades on a mounting rod inside the barrel propel the purified water toward the outlet hopper, ultimately discharging it through the outlet valve and outlet pipe. The filter outlet mechanism utilizes the rotation of the liquid storage barrel in conjunction with the inclined hole to achieve unidirectional water inflow and control the timing of water discharge. The spiral blades accelerate the discharge of purified water, allowing it to be discharged quickly, improving the efficiency and continuity of sewage treatment. It also stabilizes the outlet flow rate and pressure, facilitating the subsequent collection and utilization of treated sewage. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The filter mechanism 5 is installed at the top of the inner cavity of the housing 1. The filter mechanism 5 is arranged at the same height as the water inlet hopper 3. The top of the filter mechanism 5 is installed with a mud scraping mechanism 6. The mud scraping mechanism 6 passes through the filter mechanism 5 and extends into the interior thereof.

[0041] The filtering mechanism 5 includes a motor 51 and an annular block 55. The motor 51 is fixedly mounted on the surface of the housing 1 through a bracket. The output end of the motor 51 is fixedly connected to a transmission shaft 52. The transmission shaft 52 passes through the housing 1 and extends into the interior thereof. The other end of the transmission shaft 52 is fixedly connected to a liquid inlet barrel 53. The annular block 55 is fixedly mounted on the inner wall of the housing 1. A chute 57 is provided on the surface of the annular block 55. The liquid inlet barrel 53 is rotatably mounted inside the chute 57.

The filtering hole 54 is arranged inside the annular liquid guide groove 58. A clamping groove 56 is provided on the surface of the annular block 55.

[0042] Motor 1 51 drives transmission shaft 1 52 to rotate, causing the liquid inlet barrel 53 to rotate in the chute 57 of the annular block 55. When the liquid inlet barrel 53 rotates, impurities are thrown toward the barrel wall due to the centrifugal force. The filter holes 54 initially filter the larger particles of impurities in the sewage. The filtered sewage enters the annular liquid guide groove 58 on the inner wall of the liquid inlet barrel 53. The annular liquid guide groove 58 guides the flow of liquid, so that the sewage is evenly distributed and flows out through the filter holes 54.

[0043] The scraping mechanism 6 includes a mounting plate 61, which is fixedly mounted on the top of the inner cavity of the housing 1. A clamping plate 62 is fixedly mounted on the bottom of the mounting plate 61. A collecting hopper 64 is fixedly mounted on the bottom of the clamping plate 62. The collecting hopper 64 is used to collect filtered impurities. A leakage hole 65 is opened on the surface of the collecting hopper 64. The leakage hole 65 allows the liquid to flow out and leaves the impurities in the collecting hopper 64. A scraping member 66 is installed on the side of the clamping plate 62. The scraping member 66 is used to scrape impurities on the inner side of the liquid inlet barrel 53 to prevent the filter hole 54 and the annular liquid guide groove 58 from being blocked.

[0044] The clamping plate 62 is clamped with the clamping groove 56. A receiving groove 63 is provided on one side of the clamping plate 62. The liquid inlet barrel 53 is slidably mounted inside the receiving groove 63. The receiving groove 63 is arranged above the scraper 66.

[0045] The mud scraper 66 includes a connecting plate 661, which is fixedly mounted on the bottom of the outer surface of the clamping plate 62. Scrapers 662 are fixedly mounted on the edge of the connecting plate 661, and a groove cleaning member 663 is provided between the scrapers 662.

[0046] The scraper 662 is pressed and adapted to the inner wall of the liquid inlet barrel 53 to scrape away impurities on the inner wall of the liquid inlet barrel 53. The groove cleaning member 663 is arranged inside the annular liquid guide groove 58 to clean the annular liquid guide groove 58.

[0047] The groove cleaning member 663 includes a fixed rod 6631, which is fixedly mounted on the edge of the connecting plate 661. A rod sleeve 6632 is slidably mounted on the other end of the fixed rod 6631. A spring 6633 is fixedly connected between the rod sleeve 6632 and the connecting plate 661. The spring 6633 is sleeved on the outer surface of the fixed rod 6631. A brush disk 6634 is fixedly mounted on the end of the rod sleeve 6632 away from the fixed rod 6631. The brush disk 6634 is used to clean the annular liquid guide groove 58.

[0048] The filtering water outlet mechanism 9 is installed at the bottom of the inner cavity of the shell 1. The water outlet end of the filtering water outlet mechanism 9 is provided with a water outlet valve 10. The water outlet valve 10 is fixedly installed on the outer surface of the shell 1. The water outlet end of the water outlet valve 10 is fixedly connected to the water outlet pipe 11. The water outlet valve 10 is used to control the outflow of treated water.

[0049] The second embodiment, based on the first embodiment, see Figure 3 and Figure 9 As shown, the liquid separation mechanism 7 includes a mounting frame 71, which is fixedly mounted on the inner wall of the housing 1. A liquid baffle 72 is fixedly mounted on the inner side of the mounting frame 71, and a liquid separation hole 73 is opened on the surface of the liquid baffle 72.

[0050] An adsorption layer 8 is provided directly below the liquid separation mechanism 7 and is fixedly mounted on the inner wall of the housing 1 via a bracket.

[0051] The liquid retaining plate 72 is composed of two trapezoidal plates and two triangular plates, and the upper end of the liquid retaining plate 72 is closed. The liquid retaining plate 72 disperses the liquid after preliminary filtration and evenly flows to the adsorption layer 8 through the liquid separation holes 73;

[0052] The sewage flowing evenly through the liquid separation mechanism 7 is in full contact with the adsorption layer 8 , and the adsorption material in the adsorption layer 8 adsorbs the remaining impurities, harmful substances and odors in the sewage.

[0053] The third embodiment, based on the first and second embodiments, see Figure 10 and Figure 11As shown, the filtered water outlet mechanism 9 includes a second motor 91, and the output end of the second motor 91 is fixedly connected to a second transmission shaft 92, which passes through the shell 1 and extends to the inside thereof. A liquid storage barrel 93 is fixedly installed on the other end of the second transmission shaft 92. The liquid storage barrel 93 is used to store purified water. An inclined hole 94 is provided on the surface of the liquid storage barrel 93. The inclined hole 94 allows the purified water to enter the liquid storage barrel 93. When the liquid storage barrel 93 rotates counterclockwise, the inclined hole 94 rotates in the same direction as the liquid storage barrel 93, and the purified water enters the liquid storage barrel 93 through the inclined hole 94. Otherwise, the purified water cannot enter the liquid storage barrel 93. A liquid outlet hopper 95 is fixedly installed on the side of the liquid storage barrel 93 away from the second transmission shaft 92. The liquid outlet hopper 95 passes through the shell 1 and extends to the outside thereof. The liquid outlet end of the liquid outlet hopper 95 is arranged on one side of the water outlet valve 10;

[0054] A mounting rod 96 is fixedly mounted at the axis of the inner cavity of the liquid storage barrel 93 , and a spiral blade 97 is fixedly mounted on the surface of the mounting rod 96 . The spiral blade 97 accelerates the discharge of purified water, allowing the liquid to be quickly input into the water outlet valve 10 .

[0055] During use, the hopper door 4 at the top of the water inlet hopper 3 is opened, and sewage enters the device through the water inlet hopper 3. At this time, the sewage enters the filter mechanism 5, and the motor 1 51 is started, which drives the liquid inlet bucket 53 to rotate in the chute 57 of the annular block 55 through the transmission shaft 1 52. When the liquid inlet bucket 53 rotates, due to the centrifugal force, impurities are thrown to the cylinder wall. The filter holes 54 perform a preliminary filtration of larger particles in the sewage. The filtered sewage enters the annular liquid guide groove 58 on the inner wall of the liquid inlet bucket 53. The annular liquid guide groove 58 guides the liquid flow, so that the sewage is evenly distributed and flows out through the filter holes 54.

[0056] When the liquid inlet barrel 53 rotates, the impurities thrown toward the inner wall of the liquid inlet barrel 53 hit the collecting hopper 64, and the collecting hopper 64 collects the impurities in the sewage. At the same time, the scraping mechanism 6 works, the clamping plate 62 is clamped and fixed with the clamping groove 56, and the scraper 662 in the scraping member 66 is squeezed and adapted to the inner wall of the liquid inlet barrel 53 to scrape off the impurities attached to the inner wall of the liquid inlet barrel 53. The scraped impurities fall into the collecting hopper 64 below. The brush plate 6634 of the cleaning member 663 is pressed against the annular liquid guide groove 58 under the action of the spring 6633. As the liquid inlet barrel 53 rotates, the impurities in the annular liquid guide groove 58 and the filter hole 54 are cleaned to prevent the filter hole 54 and the annular liquid guide groove 58 from being blocked. The leakage holes 65 on the surface of the collecting hopper 64 allow the liquid to flow out, and the impurities remain in the collecting hopper 64 for subsequent cleaning.

[0057] The initially filtered sewage continues to flow downward and reaches the liquid separation mechanism 7 in the middle of the inner cavity of the shell 1. In the liquid separation mechanism 7, the mounting frame 71 is fixed to the inner wall of the shell 1, and the liquid baffle 72 is composed of two trapezoidal plates and two triangular plates and is closed at the upper end. The sewage hits the liquid baffle 72 and disperses, and flows evenly to the adsorption layer 8 below through the liquid separation holes 73 on the surface of the liquid baffle 72;

[0058] The sewage flows through the adsorption layer 8, which is fixed to the inner wall of the shell 1 by a bracket. The adsorption material inside the adsorption layer 8 adsorbs the remaining impurities, harmful substances and odors in the sewage to further purify the sewage.

[0059] The sewage purified by adsorption continues to flow downward, and the motor 2 91 is started, driving the liquid storage barrel 93 to rotate through the transmission shaft 2 92. The inclined hole 94 on the surface of the liquid storage barrel 93 matches the rotation direction of the liquid storage barrel 93. When the liquid storage barrel 93 rotates counterclockwise, the purified water enters the liquid storage barrel 93 through the inclined hole 94 and is stored. When the liquid storage barrel 93 rotates, the mounting rod 96 at the axis of the inner cavity of the liquid storage barrel 93 and the spiral blades 97 on the surface accelerate the flow of purified water toward the liquid outlet hopper 95. The purified water flows out through the liquid outlet hopper 95 and reaches the water outlet valve 10. The water outlet valve 10 is opened, and the purified water is discharged from the equipment through the water outlet pipe 11, completing the entire sewage treatment process.
