[0019] 1. When the flow rate sensor of the present invention detects that the sewage flow rate is too low, the controller starts the telescopic cylinder to start the impurity removal operation of the device, and the impurity removal mechanism drives the scraper to move on the outer surface of the filter plate. The movement of the scraper scrapes off the impurities on the filter plate on the one hand, and on the other hand, the top rod pushes the protective plate in the impurity removal trough to rotate.

During its downward sliding process, the passage between the sewage baffle and the left sewage chamber will gradually open. At this time, the sewage will enter the left sewage chamber through the diversion groove to continue filtering. This process not only ensures the continuity of sewage treatment, avoids the interruption of the entire treatment process due to the cleaning of the right sewage chamber, but also makes full use of the structural design of the device, realizes the automatic diversion of sewage, and improves the operation efficiency of the device.

[0021] 3. In the process of impurity removal, when the filter plate needs to be auxiliary jet-cleaned, the water baffle plate descends and the sealing plate is driven to descend by the transmission rod, so that the sealing plate moves to the bottom of the sealing groove to seal the jet chamber. The pressure sensor transmits the pressure signal to the controller, and then the controller starts the compressed air machine. The compressed air first impacts the circular plate in the ventilation pipe, so that the circular plate moves into the jet chamber and stretches the first spring. At this time, the compressed air smoothly enters the jet chamber through the ventilation pipe, and blows up the impurities remaining in the filter holes inside the filter plate from bottom to top, and then the scraper scrapes them away to ensure the filtering effect of the filter plate and extend its service life.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Reference Figure 1-Figure 10 As shown, the present invention provides a sewage treatment device for a chemical park, comprising a housing 1, characterized in that the housing 1 comprises an air jet mechanism 2 for cleaning air jets, a debris removal mechanism 5 for removing impurities, a treatment pool 6 for sewage filtration, a diversion mechanism 8 for sewage diversion, and a debris protection structure 9 for preventing secondary pollution;

[0044] A treatment pool 6 is symmetrically provided inside the box body 1 with respect to the central axis, a sewage chamber 61 is provided at the upper part of the treatment pool 6, a water retaining groove 62 is provided at the bottom of the sewage chamber 61, a filter chamber 63 is provided in the middle part of the treatment pool 6, a filter plate 7 is fixedly installed on the inner wall of the filter chamber 63, an injection chamber 64 is provided at the lower part of the treatment pool 6, and a sealing groove 65 is provided at the bottom of the injection chamber 64;

[0045] A plurality of telescopic cylinders 51 are fixedly installed on the top of the box body 1, and the output shafts of the plurality of telescopic cylinders 51 pass through the top of the box body 1 and are fixedly connected with a water baffle 52, which is slidably connected to the inner wall of the water baffle groove 62, and a plurality of transmission rods 53 are fixedly connected to the bottom of the water baffle plate 52, and the inner sides of the plurality of transmission rods 53 are fixedly connected with the same connecting plate 54, and a plurality of linkage rods 55 are movably connected to the bottom of the connecting plate 54, and a plurality of linkage rods 55 are fixedly connected to the bottom ends of the plurality of linkage rods 55, and the bottom ends of the scrapers 56 are in contact with the outer surface of the filter plate 7, and a top rod 58 is fixedly connected to one side of the scraper 56, and debris dropping grooves 91 are provided on both sides of the filter chamber 63, and a protective plate 92 is rotatably connected to the inner wall of the debris dropping groove 91, and a third spring 93 is movably connected to one side of the protective plate 92.

[0046] In the present embodiment, when it is necessary to remove impurities from the right sewage chamber 61, the telescopic cylinder 51 is started, and its output shaft drives the water baffle plate 52 to slide from the inside of the sewage chamber 61 to the bottom of the water baffle groove 62, so that the water baffle plate 52 closes the upper opening of the filter chamber 63, so as to stop the sewage from flowing into the filter chamber 63 and prevent the impurity removal effect from being affected. During the descent of the water baffle plate 52, the connecting plate 54 is driven to descend by the transmission rod 53. The descent of the connecting plate 54 causes the angle of the linkage rod 55 to change, thereby driving the scraper 56 to move on the outer surface of the filter plate 7. During the movement of the scraper 56, on the one hand, the impurities on the filter plate 7 are scraped off, and on the other hand, the protective plate 92 in the impurity dropping groove 91 is pushed to rotate by the push rod 58. After the protective plate 92 is rotated and opened, the scraped impurities fall into the impurity dropping groove 91. When the scraper 56 is withdrawn, the protective plate 92 is pushed off. The guard plate 92 will automatically reset under the action of the third spring 93, and the filter chamber 63 will be reclosed to prevent the sewage from flowing out of the debris chute 91 during filtration. This design can accurately control the position of the water baffle 52 through the telescopic cylinder 51, effectively preventing the sewage from continuing to flow into the filter chamber 63 during debris removal, ensuring that the debris removal work is not disturbed. The scraper 56 can stably move on the outer surface of the filter plate 7 under the action of the linkage rod 55, efficiently scrape off impurities, and improve the overall debris removal efficiency of the sewage treatment device. The cooperation between the top rod 58 and the guard plate 92 allows impurities to fall smoothly into the debris chute 91, and after the debris removal is completed, the guard plate 92 can timely close the debris chute 91, providing a strong guarantee for the continuous and stable operation of the sewage treatment device, making the debris removal method more efficient and more automated.

[0047] In a further embodiment, referring to Figure 2-Figure 3 A diversion groove 81 is provided on one side of the sewage chamber 61, and a moving groove 82 is provided on the inner wall of the diversion groove 81. A sewage baffle 83 is slidably connected to the inner wall of the moving groove 82. The tops of both ends of the sewage baffle 83 are movably connected to second springs 84. The top of the second spring 84 is fixedly connected to the inner wall of the moving groove 82. The convex block at the bottom end of the sewage baffle 83 extends into the inside of the water retaining groove 62.

[0048] In this embodiment, when the right sewage chamber 61 is being cleaned, the connecting plate 54 will touch the bottom protrusion of the sewage baffle 83 during the descent process, and generate a certain pressure on the sewage baffle 83. When the pressure reaches a certain level, the sewage baffle 83 overcomes the elastic force of the second spring 84 and slides downward on the inner wall of the movable groove 82. During its downward sliding process, it will gradually open the passage between the left sewage chamber 61 and the left sewage chamber 61. At this time, the sewage will enter the left sewage chamber 61 through the diversion groove 81 to continue filtering. This process not only ensures the continuity of sewage treatment, avoids the interruption of the entire treatment process due to the cleaning of the right sewage chamber 61, but also makes full use of the structural design of the device, realizes the automatic diversion of sewage, and improves the operation efficiency of the device.

[0049] In a further embodiment, referring to Figure 4-Figure 5 and Fig. 9 The bottom end of the transmission rod 53 passes through the inside of the filter plate 7 and is fixedly connected to a sealing plate 57. The sealing plate 57 is slidably connected to the inner wall of the sealing groove 65. Compressed air machines 21 are fixedly installed at both ends of the box body 1. The air outlet of the compressed air machine 21 is fixedly connected with a ventilation pipe 22. The ventilation pipe 22 passes through the end wall of the box body 1 and extends to the inside of the injection chamber 64.

[0050] In this embodiment, during the impurity removal operation, when the filter plate 7 needs to be auxiliary jet-cleaned, the water baffle 52 descends while the sealing plate 57 is driven to descend through the transmission rod 53, so that the sealing plate 57 moves from the jet chamber 64 to the bottom of the sealing groove 65, so that the sealing plate 57 seals the jet chamber 64, and then the compressed air machine 21 is started, and the compressed air enters the ventilation pipe 22 through the air outlet. The compressed air jets the filter plate 7 from bottom to top in the jet chamber 64, and blows up the impurities remaining in the filter holes inside the filter plate 7, and then the scraper 56 scrapes them away to ensure the filtering effect of the filter plate 7, extend its service life, provide good conditions for subsequent sewage treatment, and improve sewage treatment efficiency.

[0051] In a further embodiment, referring to Figure 4-Figure 5 A slide groove 26 is provided at one end of the ventilation pipe 22, a cross connecting frame 23 is fixedly connected to one end of the inner wall of the ventilation pipe 22, a first spring 24 is movably connected to one end of the cross connecting frame 23, a circular plate 25 is fixedly connected to one end of the first spring 24, and a circular ring on one side of the circular plate 25 is slidably connected to the inner wall of the slide groove 26.

[0052] In this embodiment, when the compressed air machine 21 starts to deliver compressed air to the ventilation pipe 22, the compressed air first hits the circular plate 25. The circular plate 25 stretches the first spring 24 under the action of the compressed air and slides along the inner wall of the slide groove 26 in a direction away from the cross connecting frame 23. At this time, the compressed air can smoothly enter the injection chamber 64 through the ventilation pipe 22 to perform jet cleaning on the filter plate 7. When the compressed air machine 21 stops working, under the elastic force of the first spring 24, the circular plate 25 is reset and the ventilation pipe 22 is reclosed to prevent sewage or impurities from flowing back into the ventilation pipe 22, thereby ensuring the normal operation and service life of the injection mechanism 2 and improving the reliability and stability of the device.

[0053] In a further embodiment, referring to Figure 4 A water collecting funnel 10 is fixedly connected to the bottom end of the jet chamber 64 . The water collecting funnel 10 penetrates the bottom wall of the box body 1 and is fixedly connected to a water delivery pipeline 11 .

[0054] In this embodiment, during the sewage treatment process, the sewage that has been preliminarily treated in the filter chamber 63 will flow into the water collecting funnel 10 at the bottom of the jet chamber 64. The water collecting funnel 10 plays a role in collecting and diverting the sewage, and then transports it to the next treatment link through the water supply pipe 11 that runs through the bottom wall of the box body 1. The cooperation between the water collecting funnel 10 and the water supply pipe 11 provides a clear flow path for the sewage, so that the water can be transported to the subsequent treatment links in an orderly manner, thereby improving the efficiency of the entire sewage treatment system.

[0055] In a further embodiment, referring to Figure 4 A flow rate sensor 12 is fixedly installed at the connection between the bottom end of the water collecting funnel 10 and the top end of the water delivery pipe 11, and a pressure sensor 13 is fixedly installed on one side of the sealing groove 65.

[0056] In this embodiment, during the sewage treatment process, when water flows from the water collecting funnel 10 into the water delivery pipe 11, the flow rate sensor 12 monitors the water flow rate in real time, and when the sealing plate 57 slides in the sealing groove 65 for sealing operation, the pressure sensor 13 can detect the pressure change in the sealing groove 65. The flow rate sensor 12 and the pressure sensor 13 can accurately monitor the water flow rate and the pressure in the sealing groove 65, providing accurate data support for the sewage treatment process, which helps to achieve automated control and optimize the treatment effect.

[0057] In a further embodiment, referring to Figure 1-Figure 10 A controller 14 is fixedly installed on one side of the box body 1. The controller 14 is electrically connected to the flow rate sensor 12, the controller 14 is electrically connected to the telescopic cylinder 51, the controller 14 is electrically connected to the pressure sensor 13, and the controller 14 is electrically connected to the compressed air machine 21.

[0058] In this embodiment, when sewage flows from the water collecting funnel 10 into the water supply pipe 11, the flow rate sensor 12 monitors the water flow rate in real time, and converts the flow rate signal into an electrical signal and transmits it to the controller 14, which is used to start the telescopic cylinder 51 and automatically control the impurity removal operation of the device during the sewage treatment process. When the sealing plate 57 slides in the sealing groove 65 for sealing operation, the pressure sensor 13 can detect the pressure signal in the sealing groove 65 and transmit it to the controller 14, which is used to start the compressed air machine 21 and automatically control the auxiliary jet cleaning operation of the device during the impurity removal process.

[0059] In a further embodiment, referring to Figure 7-Figure 8 A storage box 3 is provided below the bottom outlet of the debris dropping chute 91 , and the storage box 3 is slidably connected to the inner wall of the box body 1 .

[0060] In this embodiment, when the scraper 56 pushes the protective plate 92 to rotate and open during the impurity removal process, the scraped impurities fall into the impurity dropping groove 91, and the impurities slide downward along the impurity dropping groove 91, and finally fall into the impurity storage box 3 arranged below from the bottom outlet of the impurity dropping groove 91. When the impurities in the impurity storage box 3 accumulate to a certain extent, the impurity storage box 3 can be easily drawn out of the box body 1 to clean and process the impurities, which greatly reduces the difficulty and workload of impurity cleaning and improves the maintainability of the device.

[0061] In a further embodiment, referring to Figure 9-10 A limiting block 59 is fixedly connected at the center of the bottom end of the scraper plate 56 , a limiting groove 71 is provided inside the filter plate 7 , and the limiting block 59 is slidably connected to the inner wall of the limiting groove 71 .

[0062] In this embodiment, during the movement of the scraper 56, the limit block 59 fixedly connected at the center of the bottom end of the scraper 56 slides on the inner wall of the limit groove 71 opened inside the filter plate 7. The cooperation between the limit block 59 and the limit groove 71 plays a guiding and limiting role, ensuring that the scraper 56 maintains a stable trajectory when moving on the outer surface of the filter plate 7, and will not deviate or shake, thereby ensuring the stability of the impurity removal process.

[0063] In a further embodiment, referring to Figure 4 A water inlet pipe 4 is fixedly sleeved on the upper part of one end of the box body 1 , and the water inlet pipe 4 penetrates the end wall of the box body 1 and extends to the interior of the sewage chamber 61 .

[0064] In this embodiment, the sewage to be treated can enter the interior of the box 1 through the water inlet pipe 4, so that the sewage can flow smoothly into the sewage chamber 61, starting the entire sewage treatment process and providing stable water inlet conditions for subsequent treatment steps.

[0065] The working principle of the present invention is as follows: first, the sewage to be treated enters the sewage chamber 61 through the water inlet pipe 4, and is filtered by the filter plate 7 in the filter chamber 63. When the sewage preliminarily treated by the filter chamber 63 flows to the water delivery pipe 11 through the water collecting funnel 10, the flow rate sensor 12 monitors the flow rate of the sewage in real time, and converts the flow rate signal into an electrical signal and transmits it to the controller 14;

[0066] When the flow rate sensor 12 detects that the sewage flow rate is too low, the controller 14 starts the telescopic cylinder 51 to start the impurity removal operation of the device. The output shaft of the telescopic cylinder 51 drives the water baffle plate 52 to slide from the inside of the sewage chamber 61 to the bottom of the water baffle groove 62, so that the water baffle plate 52 closes the upper opening of the filter chamber 63, preventing the sewage from continuing to flow into the filter chamber 63, and preventing the impurity removal effect from being affected. During the descent of the water baffle plate 52, the connecting plate 54 is driven to descend through the transmission rod 53. The descent of the connecting plate 54 causes the angle of the linkage rod 55 to change, thereby driving the scraper 56 to move on the outer surface of the filter plate 7. The scraper 56 moves to scrape off the impurities on the filter plate 7, and on the other hand, the top rod 58 pushes the protective plate 92 in the impurity drop groove 91 to rotate. After the protective plate 92 is opened, the scraped impurities fall from the impurity drop groove 91 into the impurity storage box 3, and after the impurity removal is completed, the protective plate 92 can close the impurity drop groove 91 in time, which provides a strong guarantee for the continuous and stable operation of the sewage treatment device, making the impurity removal method more efficient and more automated. When the impurities in the impurity storage box 3 accumulate to a certain extent, the impurity storage box 3 can be conveniently drawn out of the box body 1 for impurity cleaning.

[0067] During the impurity removal operation, when the filter plate 7 needs to be auxiliary jet-cleaned, the water baffle plate 52 descends and the sealing plate 57 is driven to descend through the transmission rod 53, so that the sealing plate 57 moves from the jet chamber 64 to the bottom of the sealing groove 65, so that the sealing plate 57 seals the jet chamber 64. During the sealing operation, the pressure sensor 13 detects the pressure signal in the sealing groove 65 and transmits it to the controller 14, and then the controller 14 starts the compressed air machine 21. When the compressed air machine 21 starts to deliver compressed air to the ventilation pipe 22, the compressed air first impacts the circular plate 25, and the circular plate 25 stretches the first spring 24 under the action of the compressed air. , and slides along the inner wall of the slide groove 26 in the direction away from the cross connecting frame 23. At this time, the compressed air smoothly enters the injection chamber 64 through the ventilation pipe 22. The compressed air sprays the filter plate 7 from bottom to top in the injection chamber 64, blowing up the impurities remaining in the filter holes inside the filter plate 7, and then the scraper 56 scrapes them away to ensure the filtering effect of the filter plate 7 and extend its service life. When the compressed air machine 21 stops working, under the elastic force of the first spring 24, the circular plate 25 is reset and the ventilation pipe 22 is reclosed to prevent sewage or impurities from flowing back into the ventilation pipe 22, thereby ensuring the normal operation and service life of the injection mechanism 2;

[0068] When the right sewage chamber 61 is being cleaned, the connecting plate 54 will touch the bottom protrusion of the sewage baffle 83 during the descending process, and generate a certain pressure on the sewage baffle 83. When the pressure reaches a certain level, the sewage baffle 83 overcomes the elastic force of the second spring 84 and slides downward on the inner wall of the movable groove 82. During its downward sliding process, it will gradually open the passage between it and the left sewage chamber 61. At this time, the sewage will enter the left sewage chamber 61 through the diversion groove 81 to continue filtering. This process not only ensures the continuity of sewage treatment, but also avoids the interruption of the entire treatment process due to the cleaning of the right sewage chamber 61, but also makes full use of the structural design of the device, realizes the automatic diversion of sewage, and improves the operation efficiency of the device.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
