If these wastewaters are discharged without treatment, they will cause different properties and degrees of pollution in the water body, thus endangering human health and affecting industrial and agricultural production.

[0003] The patent with patent announcement number CN219384899U relates to the technical field of anaerobic reaction devices for chemical wastewater treatment, including a main body, and also includes: a three-phase separator, the three-phase separator is fixedly arranged in the main body; a stirring shaft, one end of the stirring shaft is inserted in the main body, and the movable seal passes through the three-phase separator, and the other end is fixedly connected to the output end of the motor; a stirring rod, stirring rods are respectively provided on the peripheral sides of the stirring shaft on the bottom side of the three-phase separator, and one end of the stirring rod is rotatably connected to the stirring shaft; a support ring, the stirring rod movably passes through the support ring, and the support ring is connected to the stirring shaft through a lifting assembly; this patent can make the chemical wastewater input into the main body and the microorganisms in the main body fully and evenly contact and mix, avoid the sludge in the chemical wastewater from settling at the bottom of the main body, so that the chemical wastewater can be fully treated, thereby improving the chemical wastewater treatment efficiency.

[0004] The above patent avoids the sludge in the chemical wastewater from settling at the bottom of the main body, so that the chemical wastewater can be fully treated, thereby improving the chemical wastewater treatment efficiency. However, when the wastewater is injected into the reactor, the impurities in the wastewater need to be filtered. However, after a long period of filtration, the impurities in the wastewater may accumulate on the surface and pores of the filter, causing the pores of the filter to become smaller or completely blocked. As the blockage worsens, the flow rate of the wastewater through the filter will gradually slow down, resulting in a decrease in filtration efficiency or even complete cessation of flow. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an anaerobic reaction device for treating chemical wastewater, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an anaerobic reaction device for chemical wastewater treatment, comprising a reactor, a water inlet is fixedly installed on the top of the reactor, an exhaust port is fixedly installed on the top of the reactor, a rotating shaft is rotatably installed on the top of the inner wall of the reactor, a filter is fixedly installed on the inner wall of the reactor, and a cleaning device is also provided inside the reactor; Among them, the cleaning device includes an elastic telescopic rod, a trapezoidal block, an inclined block, a disc, a vertical rod, a rotating rod and a scraper. The elastic telescopic rod is fixedly installed on the circumferential surface of the rotating shaft, the trapezoidal block is fixedly installed on the bottom of the filter screen, the disc is slidably installed on the circumferential surface of the rotating shaft, the inclined block is fixedly installed on the top of the disc, the vertical rod is fixedly installed on the bottom of the disc, the rotating rod is rotatably installed on the circumferential surface of the rotating shaft, and the scraper is fixedly installed on one end of the rotating rod away from the rotating shaft. The rotation of the rotating shaft will drive the rotating rod to rotate, and the rotation of the rotating rod will stir the wastewater. The stirring can make the organic matter in the wastewater fully contact with the anaerobic microorganisms in the reactor, thereby accelerating the degradation process of the organic matter.

[0007] According to the above technical solution, an inclined surface is provided on the side where the trapezoidal block and the inclined block are close to each other. The inclined surface is provided on the trapezoidal block and the inclined block to facilitate the trapezoidal block to push the inclined block to move downward. A No. 1 torsion spring is provided between the rotating rod and the rotating shaft. The No. 1 torsion spring is provided to facilitate driving the rotating rod back to its original position. The bottom of the vertical rod is in contact with the top of the rotating rod.

[0008] According to the above technical scheme, a discharge device and a storage device are also provided inside the reactor, and the discharge device includes a placement frame, a rotating plate, a pressure rod and an opening and closing plate. The placement frame is fixedly installed on the top of the filter screen, and the pressure rod slides through the top of the filter screen.

The rotating plate rotates downward to push impurities accumulated on the outside of the placement frame into the placement frame, and the rotating plate rotates downward to seal the placement frame to prevent air from entering the reactor when the impurities in the placement frame are discharged. After the oxygen in the air enters the anaerobic reactor, the oxygen may undergo an oxidation reaction with organic matter in the wastewater and be converted into more easily degradable substances, which may cause pre-oxidation of the organic matter and may affect the stability and efficiency of the entire wastewater treatment process.

The outer frame is fixedly installed on the outer wall of the reactor, the storage box is slidably installed on the inner wall of the outer frame, and the inclined plate is fixedly installed on the bottom of the filter screen. The downward sliding of the round rod will push the opening and closing plate to rotate downward. When the opening and closing plate rotates downward, it will lose contact with the elastic telescopic plate, and the elastic telescopic plate will be driven to rotate downward by the No. 4 torsion spring. The downward rotation of the elastic telescopic plate will push the impurities on the surface of the opening and closing plate to separate from the opening and closing plate, thereby preventing impurities from adhering to the surface of the opening and closing plate and making it impossible to completely collect the impurities.

[0010] According to the above technical solution, a No. 2 torsion spring is provided between the rotating plate and the placement frame, and the No. 2 torsion spring is provided to drive the rotating plate back to its original position. A No. 3 torsion spring is provided between the opening and closing plate and the discharge port, and the No. 3 torsion spring is provided to drive the opening and closing plate back to its original position.

The push rod is rotatably installed at the bottom of the opening and closing plate, the push block is slidably installed on the side of the inclined plate close to the outer frame, the push block is rotatably installed at the end of the push rod away from the closing plate, the cross bar is slidably installed on the inner wall of the outer frame, the latch is fixedly installed at the bottom of the cross bar, and the fixed block is fixedly installed on the inner wall of the storage box. The downward sliding of the cross bar will push the latch to insert into the fixed block. The insertion of the latch into the fixed block will limit the storage box to prevent the impurities from falling into the outer frame when the impurities are discharged into the storage box, so that the impurities are not completely collected, and the impurities falling into the outer frame will increase the difficulty of cleaning the outer frame and reduce the work efficiency of the staff.

[0012] According to the above technical solution, the storage device includes a rotating plate and a sliding baffle, the rotating plate is rotatably installed on the inner wall of the outer frame, the rotating plate is divided into an inner plate and an outer plate, the outer plate is rotatably installed on the inner wall of the outer frame, the inner plate is slidably installed on the inner wall of the outer plate, the outer wall of the outer frame is provided with a square groove, the sliding baffle is slidably installed on the inner wall of the square groove, and the side of the sliding baffle away from the inclined plate is provided with an inclined surface, the sliding baffle will be pushed by the No. 2 spring so that the sliding baffle contacts the bottom of the rotating plate, and the sliding baffle will limit the rotating plate, so that when the storage box is pulled out, the impurities will fall on the surface of the rotating plate and will not fall into the outer frame, and the rotating plate will seal the outer frame so that when the impurities are discharged, the air will not enter the reactor, thereby enhancing the sealing effect when the impurities are discharged.

[0013] According to the above technical solution, a No. 1 spring is provided between the cross bar and the outer frame, and the No. 1 spring is provided to drive the cross bar back to its original position. A No. 2 spring is provided between the sliding baffle rod and the outer frame, and the No. 2 torsion spring is provided to drive the sliding baffle rod to slide and limit the rotating plate. A fixing groove is provided on the top of the fixed block, and the shape of the fixing groove matches the fixed block. A No. 3 spring is provided between the outer plate and the inner plate, and the No. 3 spring is provided to push the inner plate to slide in the direction away from the outer plate.

[0014] The present invention provides an anaerobic reaction device for treating chemical wastewater, which has the following beneficial effects: (1) In the present invention, the rotation of the shaft drives the elastic telescopic rod to rotate and scrape the surface of the filter screen, thereby preventing the filter screen from being blocked by excessive impurities in the wastewater, which results in poor entry of wastewater. The downward movement of the vertical rod drives the rotating rod to rotate downward, which drives the scraper to move. The scraper will scrape off the microbial sediment attached to the inner wall of the reactor, thereby increasing the reaction rate between the microorganisms and the wastewater. The rotation of the shaft drives the rotating rod to rotate, which stirs the wastewater. The stirring enables the organic matter in the wastewater to fully contact with the anaerobic microorganisms in the reactor, thereby accelerating the degradation process of the organic matter.

[0015] (2) In the present invention, the rotating plate rotates downward to push the impurities accumulated on the outside of the placement frame into the inside of the placement frame, and the rotating plate rotates downward to seal the placement frame to prevent air from entering the reactor when the impurities in the placement frame are discharged. After the oxygen in the air enters the anaerobic reactor, the oxygen may react with the organic matter in the wastewater to produce an oxidation reaction and transform it into a more easily degradable substance, which may lead to the pre-oxidation of the organic matter and may affect the stability and efficiency of the entire wastewater treatment process. The round rod slides downward to push the opening and closing plate to rotate downward. When the opening and closing plate rotates downward, it loses contact with the elastic telescopic plate, and the elastic telescopic plate is driven by the No. 4 torsion spring to rotate downward. The downward rotation of the elastic telescopic plate pushes the impurities on the surface of the opening and closing plate to separate from the opening and closing plate, thereby preventing the impurities from adhering to the surface of the opening and closing plate and making it impossible to completely collect the impurities.

[0016] (3) In the present invention, the downward sliding of the cross bar will push the latch to be inserted into the interior of the fixed block. The insertion of the latch into the interior of the fixed block will limit the storage box, preventing the impurities from falling into the outer frame when the impurities are discharged into the storage box, resulting in incomplete collection of the impurities. Impurities falling into the outer frame will increase the difficulty of cleaning the outer frame and reduce the work efficiency of the staff. When the storage box is completely taken out, the contact with the sliding baffle rod will be released, and the sliding baffle rod will be pushed by the No. 2 spring to make the sliding baffle rod contact with the bottom of the rotating plate. The sliding baffle rod will limit the rotating plate, so that when the storage box is pulled out, the impurities will fall on the surface of the rotating plate and will not fall into the outer frame. The rotating plate will seal the outer frame so that air will not enter the reactor when the impurities are discharged, thereby enhancing the sealing effect when the impurities are discharged.

The rotating plate 132 rotates downward to push the impurities accumulated outside the placement frame 131 into the placement frame 131, and the rotating plate 132 rotates downward to seal the placement frame 131 to prevent air from entering the reactor 1 when the impurities inside the placement frame 131 are discharged. After the oxygen in the air enters the anaerobic reactor, the oxygen may undergo an oxidation reaction with the organic matter in the wastewater and be converted into a more easily degradable substance, which may cause pre-oxidation of the organic matter and may affect the stability and efficiency of the entire wastewater treatment process.

[0024] The discharge device also includes an elastic telescopic plate 134, a round rod 136, an inclined plate 137, an outer frame 138 and a storage box 139. The elastic telescopic plate 134 is rotatably mounted on the inner wall of the placement frame 131, one end of the round rod 136 is rotatably mounted on the side of the pressure rod 133 close to the opening and closing plate 135, and the other end of the round rod 136 is slidably mounted on the side of the opening and closing plate 135 close to the pressure rod 133.

The inclined plate 137 is fixedly mounted on the bottom of the filter screen 5. The round rod 136 slides downward to push the opening and closing plate 135 to rotate downward. When the opening and closing plate 135 rotates downward, it will lose contact with the elastic telescopic plate 134, and the elastic telescopic plate 134 will be driven by the No. 4 torsion spring to rotate downward. The downward rotation of the elastic telescopic plate 134 will push the impurities on the surface of the opening and closing plate 135 to separate from the opening and closing plate 135, so as to prevent the impurities from adhering to the surface of the opening and closing plate 135 and making it impossible to completely collect the impurities.

[0025] A No. 2 torsion spring is provided between the rotating plate 132 and the placement frame 131, and the No. 2 torsion spring is provided to drive the rotating plate 132 to return to its original position.

[0026] The storage device includes a push rod 141, a push block 142, a cross bar 143, a latch 144 and a fixed block 145. The push rod 141 is rotatably mounted at the bottom of the opening and closing plate 135, the push block 142 is slidably mounted on the side of the inclined plate 137 close to the outer frame 138, the push block 142 is rotatably mounted on the end of the push rod 141 away from the closing plate 135, the cross bar 143 is slidably mounted on the inner wall of the outer frame 138, the latch 144 is fixedly mounted on the bottom of the cross bar 143, and the fixed block 145 is fixedly mounted on the inner wall of the storage box 139. The downward sliding of the cross bar 143 will push the latch 144 to insert into the fixed block 145. The insertion of the latch 144 into the fixed block 145 will limit the storage box 139 to prevent the impurities from falling into the outer frame 138 when the impurities are discharged into the storage box 139, so that the impurities are not completely collected, and the impurities falling into the outer frame 138 will increase the difficulty of cleaning the outer frame 138, thereby reducing the work efficiency of the staff.

[0027] The storage device includes a rotating plate 146 and a sliding baffle 147. The rotating plate 146 is rotatably installed on the inner wall of the outer frame 138. The rotating plate 146 is divided into an inner plate and an outer plate. The outer plate is rotatably installed on the inner wall of the outer frame 138, and the inner plate is slidably installed on the inner wall of the outer plate. A square groove is opened on the outer wall of the outer frame 138, and a sliding baffle 147 is slidably installed on the inner wall of the square groove. A slope is provided on the side of the sliding baffle 147 away from the inclined plate 137. The sliding baffle 147 will be pushed by the No. 2 spring so that the sliding baffle 147 contacts the bottom of the rotating plate 146. Then, the sliding baffle 147 will limit the rotating plate 146, so that when the storage box 139 is drawn out, the impurities will fall on the surface of the rotating plate 146 and will not fall into the outer frame 138. In addition, the rotating plate 146 will seal the outer frame 138 so that air will not enter the reactor 1 when the impurities are discharged, thereby enhancing the sealing effect when the impurities are discharged.

[0028] A No. 1 spring is provided between the cross bar 143 and the outer frame 138. The No. 1 spring is provided to drive the cross bar 143 back to its original position.

The No. 2 torsion spring is provided to drive the sliding baffle rod 147 to slide and limit the rotating plate 146. A fixing groove is provided on the top of the fixing block 145. The shape of the fixing groove matches the fixing block 145. A No. 3 spring is provided between the outer plate and the inner plate. The No. 3 spring is provided to push the inner plate to slide away from the outer plate.

[0029] When the embodiment is working, when the elastic telescopic rod 6 rotates, the impurities on the surface of the filter screen 5 will be pushed into the placement frame 131 for temporary collection. When the disc 9 slides downward, the pressure rod 133 will slide downward. The downward sliding of the pressure rod 133 will press the rotating plate 132 to rotate downward. The rotating plate 132 will rotate downward to push the impurities accumulated outside the placement frame 131 into the placement frame 131. The rotating plate 132 will seal the placement frame 131 to prevent the impurities inside the placement frame 131 from being discharged. When the gas enters the reactor 1, the pressure rod 133 moves downward, which drives the round rod 136 to move downward. The round rod 136 slides downward and pushes the opening and closing plate 135 to rotate downward. When the opening and closing plate 135 rotates downward, it loses contact with the elastic expansion plate 134, and the elastic expansion plate 134 is driven by the No. 4 torsion spring to rotate downward. The downward rotation of the elastic expansion plate 134 pushes the impurities on the surface of the opening and closing plate 135 to separate from the opening and closing plate 135, so that the impurities can slide into the storage box 139 through the inclined plate 137 for collection.

[0030] When the opening and closing plate 135 rotates downward, it will push the push rod 141 to slide downward. When the push rod 141 slides downward, it will push the push block 142 to slide downward. The downward sliding of the push block 142 will push the cross bar 143 to slide downward. The downward sliding of the cross bar 143 will push the latch 144 to insert into the fixed block 145. The insertion of the latch 144 into the fixed block 145 will limit the storage box 139, preventing the impurities from falling into the outer frame 138 when the impurities are discharged into the storage box 139. As a result, the impurities are not completely collected and the impurities fall into the outer frame 138, which will increase the difficulty of cleaning the outer frame 138. When the impurities in the storage box 139 need to be cleaned, the storage box 139 will be pulled out from the inside of the outer frame 138. When the storage box 139 is pulled out, it will push the rotating plate 146 to rotate in the direction of the sliding stop rod 147. When the storage box 139 is completely taken out, the locking with the sliding stop rod 147 will be released. When the storage box 139 is in contact with the outer frame 138, the sliding baffle 147 will be pushed by the No. 2 spring, so that the sliding baffle 147 contacts the bottom of the rotating plate 146, and the sliding baffle 147 will limit the rotating plate 146, so that when the storage box 139 is drawn out, the impurities will fall on the surface of the rotating plate 146 and will not fall into the outer frame 138, and the rotating plate 146 will seal the outer frame 138 so that the air will not enter the reactor 1 when the impurities are discharged, thereby enhancing the sealing effect when the impurities are discharged. When the impurities inside the storage box 139 are cleaned up and the storage box 139 is placed in the outer frame 138, the storage box 139 will contact the inclined surface of the sliding baffle 147, and the sliding baffle 147 will be pushed back to its original position by the storage box 139. When the sliding baffle 147 returns to its original position, the limit on the rotating plate 146 will be released, and the rotating plate 146 will rotate downward, and the impurities on the surface of the rotating plate 146 will slide toward the inside of the storage box 139.
