Although the patent solves the above problems, there is still a problem that the sewage discharge pipe of the connecting device is easily affected by the blockage of the filter and backflows. Therefore, it is very necessary to design a sewage discharge device for chemical environmental protection to prevent sewage backflow. Summary of the invention

[0004] The purpose of the present invention is to provide a sewage discharge device for chemical environmental protection to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a sewage discharge device used for chemical environmental protection, comprising an infusion box, a filtering structure and a connecting component; the filtering structure comprises a reaction box, a filter box, a barrel cover, a material filter cartridge, a filter plate, a side guide plate, a layered filter screen, and an output bottom box, the reaction box is fixedly connected to the side of the infusion box, the filter box is arranged below the reaction box, the barrel cover is arranged on both sides of the reaction box, the material filter cartridge is arranged on the inner side of the barrel cover, the filter plate is fixedly connected to the side of the material filter cartridge, and the side guide plate is fixedly connected to the reaction box.

When the liquid in the reaction box enters the infusion box and flows back, the reflux hydraulic pressure will push the sliding sleeve closer to the valve shaft, so that the valve shaft is sleeved on the outside of the valve shaft, blocking the groove of the feeding port, thereby using the liquid pressure on both sides of the sliding sleeve to drive the sliding sleeve to move to control the connection, thereby preventing the liquid from flowing back. At the same time, the liquid entering the reaction box reacts with the elements contained in the wastewater through the material placed on the inner side of the material filter cartridge, and then the material passes through the material filter cartridges to allow the reactants to form reactant precipitation. Before the waste liquid enters the material filter cartridges, the waste residue in the waste liquid will be filtered through the filter plate, and the precipitation formed by the reaction of the material filter cartridge will be filtered through the filter plate again. According to the different pore sizes of the stratified filter screen, the water-insoluble particulate materials in the waste liquid are stratified according to the particle size, so that the materials that have not passed through the stratified filter screen block the inner side of the stratified filter screen, and the materials are allowed to sink to form precipitation, thereby improving the filtration effect.

[0006] According to the above technical solution, a material pushing and cleaning device is provided on the bottom side of the reaction box, and the material pushing and cleaning device includes a guide structure and a push plate structure, the guide structure includes a lower liquid channel, a guide fan, a transmission gear, and a push gear rod, the lower liquid channel is fixedly connected to the bottom end of the reaction box, the guide fan is rotatably connected to the inner side of the lower liquid channel, the transmission gear is fixedly connected to the end of the guide fan output shaft, the push gear rod is meshed and connected below the transmission gear, the push plate structure includes a sliding rod, a fixed rod filter plate, and a sliding filter plate, the sliding rod is slidably connected to the upper surface of the filter box, the fixed rod filter plate is fixedly connected to the outer side of the sliding rod, the sliding filter plate is slidably connected to the outer side of the sliding rod, the rear side of the sliding rod is provided with a spring, and the sliding The rod is fixedly connected to the pushing tooth rod, the bottom surface of the filter box is provided with a filter screen, and the bottom surface of the filter box is communicated downward, and the bottom side of the filter box is fixedly connected to the bottom side of the filter box, and the sliding filter plate includes a shaking plate assembly, and the shaking plate assembly includes a side top plate, a metal arc plate, a convex strip, and a shaking groove plate, the side top plate is fixedly connected to the side surface of the sliding filter plate, the metal arc plate passes through the side surface of the bottom filter plate, the convex strip is fixedly connected to the bottom surface of the bottom filter plate, the shaking groove plate is fixedly connected to the bottom end side surface of the metal arc plate, the top of the metal arc plate is provided with a triangular strip, and the bottom end of the metal arc plate is fixedly connected to an inclined push plate, and the shaking groove plate is fixedly connected to the side surface of the inclined push plate. Through the above structure, when the liquid in the reaction box flows downward through the lower liquid channel, the liquid in the lower liquid channel flows The moving liquid drives the guide fan to rotate, which will make the transmission gear connected to the axis of the guide fan rotate, and the transmission gear drives the meshing push gear rod to move. The moving push gear rod makes the connected sliding rod move together, and the fixed rod filter plate outside the sliding rod will move with it, so that the fixed rod filter plate is close to the sliding filter plate, and the sliding filter plate squeezes the rear spring. The fixed rod filter plate and the sliding filter plate move to gather the filtered materials on the inside, and the fixed rod filter plate and the sliding filter plate fit the bottom surface of the filter box to clean the filter screen on the bottom surface of the filter box, so that the accumulated filter waste is discharged through the bottom of the filter box, which plays a cleaning role. When the push gear rod is away from the transmission gear, the transmission gear disengages from the push gear rod for a distance. At this time, the spring releases the elastic force to make the sliding rod move and The sliding rod pushes the push gear rod connected at the end to move, so that the push gear rod meshes with the transmission gear again, so that the transmission gear rotates in the opposite direction and the liquid refluxes. When the liquid pressure in the reaction box is positive and greater than the spring force, the liquid inside the reaction box squeezes the guide fan blades to make the transmission gear rotate to achieve pressure relief. In addition, the movement of the sliding filter plate will push the top plate to contact the triangular strip on the top side of the metal arc plate, so that the metal arc plate moves downward and slides with the bottom filter plate and pulls the spring, so that the inclined push plate at the end of the metal arc plate pushes the shaking groove plate on the side, so that the top surface of the shaking groove plate contacts the convex strip. When the shaking groove plate moves to the left, the bottom filter plate vibrates, which cleans the bottom filter plate and shakes off the sediment accumulated on the bottom filter plate. When the shaking groove plate moves to the left, the spring releases the elastic force to reset the metal arc plate.At this time, the top surface of the shaking groove plate contacts the convex strips to make the metal arc plate shake, thereby pushing the metal arc plate to the left to shake off the stains on the inclined push plate.

Through the above structure, when the solid rod filter plate and the sliding filter plate are close to each other, the shrinkage airbag is squeezed between the solid rod filter plate and the sliding filter plate. The shrink air bag shrinks the internal space of the shrink air bag, and transports the air inside the shrink air bag to the inside of the gas storage layer plate through the connected air supply pipe, and outputs gas at the same time from the air outlet pipes connected through the side of the gas storage layer plate. The connection between the air outlet pipe and the gas storage layer plate is a one-way valve. The blown gas flows upward from the bottom of the material filter cartridge, and the bubbles formed by the blown gas blow away the sediment attached to the outside of the material filter cartridge through the floating bubbles. At the same time, the bubbles are used to drive the liquid around the material filter cartridge to flow. At the same time, when the fixed rod filter plate and the sliding filter plate are separated, the outside air will be transmitted to the inside of the shrink air bag through the suction pipe, and the air inside the shrink air bag can be replenished. The gas filled inside the shrink air bag plays a buffering role, limiting the rate of approach between the fixed rod filter plate and the sliding filter plate, reducing the speed of gas discharge, and increasing the duration of gas discharge.

When the liquid in the reaction box 3 enters the infusion box 1 and flows back, the reflux hydraulic pressure will push the sliding sleeve 23 to approach the valve shaft 22, so that the valve shaft 22 is sleeved on the outside of the valve shaft 22, and the feeding port 24 is blocked. The liquid on both sides of the sliding sleeve 23 is pressed to drive the sliding sleeve 23 to move to control the connection, thereby preventing the liquid from flowing out. Due to the effect of reflux, the liquid entering the reaction box 3 reacts with the elements contained in the wastewater through the material placed on the inner side of the material filter cartridge 9, and then the material passes through the material filter cartridges 9 to allow the reactants to form reactant precipitates. Before the waste liquid enters the material filter cartridges 9, the waste residue in the waste liquid will be filtered through the filter plate 10, and the precipitate formed by the reaction of the material filter cartridge 9 will be filtered through the filter plate 10 again.

[0028] A material pushing and cleaning device 5 is provided on the bottom side of the reaction box 3. The material pushing and cleaning device 5 includes a guide structure and a push plate structure. The guide structure includes a lower liquid channel 51, a guide fan 52, a transmission gear 53, and a push gear rod 54. The lower liquid channel 51 is fixedly connected to the bottom end of the reaction box 3, the guide fan 52 is rotatably connected to the inner side of the lower liquid channel 51, the transmission gear 53 is fixedly connected to the end of the output shaft of the guide fan 52, and the push gear rod 54 is meshed and connected below the transmission gear 53. The push plate structure includes a sliding rod 55, a fixed rod filter plate 56, and a sliding filter plate 57. The sliding rod 55 is slidably connected to the upper surface of the filter box 4, the fixed rod filter plate 56 is fixedly connected to the outer side of the sliding rod 55, and the sliding filter plate 57 is slidably connected to the outer side of the sliding rod 55. The rear side of the sliding rod 55 is provided with The spring, the sliding rod 55 is fixedly connected to the pushing gear rod 54, the bottom surface of the filter box 4 is provided with a filter screen, and the bottom surface of the filter box 4 is connected downwardly, the bottom side of the filter box 4 is fixedly connected to the bottom filter plate 58, the sliding filter plate 57 includes a shaking plate assembly, the shaking plate assembly includes a side top plate 571, a metal arc plate 572, a convex strip 573, and a shaking groove plate 574, the side top plate 571 is fixedly connected to the side of the sliding filter plate 57, the metal arc plate 572 passes through the side of the bottom filter plate 58, the convex strip 573 is fixedly connected to the bottom surface of the bottom filter plate 58, the shaking groove plate 574 is fixedly connected to the bottom end side of the metal arc plate 572, the top of the metal arc plate 572 is provided with a triangular strip, the bottom end of the metal arc plate 572 is fixedly connected to an inclined push plate, and the shaking groove plate 574 is fixedly connected to the side of the inclined push plate. The structure is as follows: when the liquid in the reaction box 3 flows downward through the lower liquid channel 51, the liquid flowing through the lower liquid channel 51 drives the guide fan 52 to rotate, which makes the transmission gear 53 connected to the axis of the guide fan 52 rotate, and the transmission gear 53 drives the meshing push gear rod 54 to move, and the moving push gear rod 54 makes the connected sliding rod 55 move together, and the fixed rod filter plate 56 outside the sliding rod 55 moves with it, so that the fixed rod filter plate 56 is close to the sliding filter plate 57, and the sliding filter plate 57 squeezes the rear spring, and the fixed rod filter plate 56 and the sliding filter plate 57 move to gather the filtered materials on the inside, and the fixed rod filter plate 56 and the sliding filter plate 57 are attached to the bottom surface of the filter box 4 to clean the filter screen on the bottom surface of the filter box 4, so that the accumulated filtered waste The slag is discharged through the bottom of the filter box 4, which plays a cleaning role. When the push gear rod 54 is away from the transmission gear 53, the transmission gear 53 is separated from the push gear rod 54 for a distance. At this time, the spring releases the elastic force to allow the sliding rod 55 to move, and the sliding rod 55 pushes the push gear rod 54 connected at the end to move, so that the push gear rod 54 is meshed with the transmission gear 53 again, so that the transmission gear 53 rotates in the opposite direction to allow the liquid to flow back. When the liquid pressure in the reaction box 3 is large and greater than the spring elastic force, the liquid inside the reaction box 3 squeezes the guide fan blade 52 to allow the transmission gear 53 to rotate, thereby achieving pressure relief. In addition, the movement of the sliding filter plate 57 will push the top plate 571 to contact the triangular bar on the top side of the metal arc plate 572, allowing the metal arc plate 572 to move downward and slide with the bottom filter plate 58 and pull the spring.Thus, the inclined push plate at the end of the metal arc plate 572 pushes the shaking groove plate 574 on the side, so that the top surface of the shaking groove plate 574 contacts the convex strip 573. When the shaking groove plate 574 moves to the left, the bottom filter plate 58 vibrates, which plays a cleaning role on the bottom filter plate 58, so that the sediment accumulated on the bottom filter plate 58 is shaken off. When the shaking groove plate 574 moves to the left, the spring releases the elastic force to reset the metal arc plate 572. At this time, the top surface of the shaking groove plate 574 contacts the convex strip 573, so that the metal arc plate 572 itself shakes, thereby pushing the metal arc plate 572 to the left and shaking off the dirt on the inclined push plate.

[0029] Working principle: connect the industrial waste output port with the connecting component 2 on the side of the infusion box 1, let the liquid enter the feeding port 24 of the connecting component 2, and let the liquid push the sliding sleeve 23 on the outside of the valve shaft 22 backwards through pressure, so that the sliding sleeve 23 pulls the spring when it moves, so that the sliding sleeve 23 is separated from the valve shaft 22, and the channel in the middle of the sliding sleeve 23 is connected to the feeding port 24, so that the waste liquid enters the interior of the infusion box 1 through the sliding sleeve 23. When the liquid in the reaction box 3 enters the infusion box 1 and flows back, the reflux hydraulic pressure will push the sliding sleeve 23 to approach the valve shaft 22, so that the valve shaft 22 is sleeved on the outside of the valve shaft 22, and the feeding port 24 is blocked. The groove is blocked, so that the liquid on both sides of the sliding sleeve 23 is used to apply pressure and drive the sliding sleeve 23 to move to control the connection, thereby preventing the liquid from flowing back. At the same time, the liquid entering the reaction box 3 reacts with the elements contained in the wastewater through the material placed inside the material filter cartridge 9, and then the material passes through the material filter cartridges 9 to allow the reactants to form reactant precipitation. Before the waste liquid enters the material filter cartridges 9, the waste residue in the waste liquid will be filtered through the filter plate 10, and the precipitation formed by the reaction of the material filter cartridge 9 will be filtered again through the filter plate 10. Some precipitation and waste materials with particle sizes smaller than the aperture of the filter plate 10 continue to flow in the reaction box 3, so that the liquid in the reaction box 3 is filtered again through the layered filter screen 12. According to the different pore sizes of the layered filter screen 12, the water-insoluble particulate materials in the waste liquid are layered according to the particle size, so that the inner side of the layered filter screen 12 is blocked by the particulate materials that have not passed through the layered filter screen 12, and the materials are allowed to sink to form precipitation, thereby improving the filtering effect;

[0030] When the liquid in the reaction box 3 flows downward through the lower liquid channel 51, the liquid flowing through the lower liquid channel 51 drives the guide blade 52 to rotate, and while the guide blade 52 rotates, the transmission gear 53 connected to the axis of the guide blade 52 is driven to rotate, and the transmission gear 53 drives the meshing push gear rod 54 to move, and the moving push gear rod 54 moves the connected sliding rod 55 together, and the fixed rod filter plate 56 on the outer side of the sliding rod 55 moves with it, and slides with the sliding filter plate 57 through the sliding rod 55, so that the fixed rod filter plate 56 is close to The sliding filter plate 57 is pressed against the rear spring, and the fixed rod filter plate 56 and the sliding filter plate 57 are moved to gather the filtered materials on the inside, and the fixed rod filter plate 56 and the sliding filter plate 57 are pressed against the bottom surface of the filter box 4 to clean the filter screen on the bottom surface of the filter box 4, so that the accumulated filtered waste residue is discharged through the bottom of the filter box 4, which plays a cleaning role. When the push gear rod 54 is away from the transmission gear 53, the transmission gear 53 is separated from the push gear rod 54 for a distance. At this time, the spring releases its elastic force, allowing the sliding rod 55 to move, and The sliding rod 55 pushes the toothed rod 54 connected at the end to move, so that the toothed rod 54 meshes with the transmission gear 53 again, so that the transmission gear 53 rotates in the opposite direction to allow the liquid to flow back. When the liquid pressure in the reaction box 3 is positive and greater than the spring force, the liquid inside the reaction box 3 squeezes the guide fan blade 52 to allow the transmission gear 53 to rotate, thereby achieving pressure relief. In addition, the movement of the sliding filter plate 57 will push the top plate 571 to contact the triangular strip on the top side of the metal arc plate 572, so that the metal arc plate 572 moves downward to slide with the bottom filter plate 58 and pull the spring, thereby allowing The inclined push plate at the end of the metal arc plate 572 pushes the shaking groove plate 574 on the side, so that the top surface of the shaking groove plate 574 contacts the convex strip 573. When the shaking groove plate 574 moves to the left, the bottom filter plate 58 vibrates, which has a cleaning effect on the bottom filter plate 58, and the mud and sand accumulated on the bottom filter plate 58 are shaken off. When the shaking groove plate 574 moves to the left, the spring releases the elastic force to reset the metal arc plate 572. At this time, the top surface of the shaking groove plate 574 contacts the convex strip 573 to make the metal arc plate 572 shake itself, thereby pushing the metal arc plate 572 to the left and shaking off the stains on the inclined push plate.

The shrinkage airbag 61 is fixedly connected to the side of the fixed rod filter plate 56, the air intake pipe 62 is fixedly connected to the side of the shrinkage airbag 61, and the air supply pipe 63 is fixedly connected to the upper surface of the shrinkage airbag 61. The exhaust structure includes an air storage layer plate 64 and an air outlet pipe 65. The air storage layer plate 64 is fixedly connected to the bottom of the material filter cartridge 9, and the air outlet pipes 65 are fixedly connected to the two side surfaces of the air storage layer plate 64. The side surface of the shrinkage airbag 61 is fixedly connected to the sliding filter plate 57, the air supply pipe 63 is fixedly connected to the air storage layer plate 64, and the air outlet pipes 65 are equidistantly distributed on both sides of the air storage layer plate 64. Through the above structure, when the fixed rod filter plate 56 and the sliding filter plate 57 are close to each other, the shrinkage airbag between the fixed rod filter plate 56 and the sliding filter plate 57 is squeezed. 61, so that the internal space of the shrink airbag 61 shrinks, and the air inside the shrink airbag 61 is transported to the inside of the air storage layer plate 64 through the connected air supply pipe 63, and the gas is output simultaneously through the air outlet pipe 65 connected to the side of the air storage layer plate 64. The connection between the air outlet pipe 65 and the air storage layer plate 64 is a one-way valve. The blown gas flows upward from the bottom of the material filter cartridge 9, and the bubbles formed by the blown gas blow off the sediment attached to the outside of the material filter cartridge 9 through the floating bubbles. At the same time, the bubbles are used to drive the liquid around the material filter cartridge 9 to flow. At the same time, when the fixed rod filter plate 56 and the sliding filter plate 57 are separated from each other, the outside air will be transmitted to the inside of the shrink airbag 61 through the suction pipe 62, and the air inside the shrink airbag 61 is replenished. The gas filled in the shrink airbag 61 plays a buffering role, limits the rate of approach between the fixed rod filter plate 56 and the sliding filter plate 57, reduces the speed of gas discharge, and increases the duration of gas discharge.

[0033] The bottom surface of the filter box 4 is provided with a pushing device 8, which includes a stacking bottom box 81, a baffle 82, a slide guide bar 83, a scraper bar 84, a fixed rod shaft seat 85, and a push rod 86. The stacking bottom box 81 is fixedly connected to the bottom of the filter box 4, the baffle 82 is slidably connected to the side of the stacking bottom box 81, the slide guide bar 83 is fixedly connected to the side of the stacking bottom box 81, the scraper bar 84 is fixedly connected to the side of the baffle 82, the fixed rod shaft seat 85 is fixedly connected to the side of the stacking bottom box 81, and the push rod 86 is fixedly connected to the fixed rod shaft seat 85. On the inside, the scraper strip 84 is slidably connected to the slide guide strip 83, the baffle plate 82 is slidably connected to the push rod 86, and a filter screen is provided on the bottom surface of the filter box 4. Through the above structure, by pushing the push rod 86, the push rod 86 is allowed to slide on the fixed rod shaft seat 85, and the push rod 86 moves to drive the connected baffle plate 82 to slide on the inner side of the slide guide strip 83, and the baffle plate 82 no longer blocks the filter screen on the bottom side of the filter box 4, so that the waste sediment on the bottom side of the filter box 4 is discharged through the filter screen to the bottom box 81 for collection, thereby achieving the purpose of convenient cleaning.

[0034] Working principle: When the fixed rod filter plate 56 and the sliding filter plate 57 are close to each other, the shrinkage airbag 61 between the fixed rod filter plate 56 and the sliding filter plate 57 is squeezed to shrink the internal space of the shrinkage airbag 61, and the air inside the shrinkage airbag 61 is transported to the inside of the gas storage layer plate 64 through the connected air supply pipe 63, and the gas is outputted from the outlet pipe 65 connected to the side of the gas storage layer plate 64 at the same time. The connection between the outlet pipe 65 and the gas storage layer plate 64 is a one-way valve. The blown gas flows upward from the bottom of the material filter cartridge 9, and the bubbles formed by the blown gas blow the sediment attached to the outside of the material filter cartridge 9 through the floating The bubbles are blown away, and at the same time, the bubbles are used to drive the liquid flow around the material filter cartridge 9, so that the liquid flow frequency of the material filter cartridge 9 axis increases, and the reaction rate and effect between the waste material and the material in the material filter cartridge 9 are improved. At the same time, when the fixed rod filter plate 56 and the sliding filter plate 57 are separated, the outside air will be transmitted to the inside of the contraction airbag 61 through the suction pipe 62, and the air inside the contraction airbag 61 is replenished. The gas filled in the contraction airbag 61 plays a buffering role, limiting the approach rate between the fixed rod filter plate 56 and the sliding filter plate 57, reducing the speed of gas discharge, and increasing the duration of gas discharge;

[0035] When there is too much sediment material accumulated inside the filter box 4, the push rod 86 is pushed to slide on the fixed rod shaft seat 85, and the push rod 86 moves to drive the connected baffle 82 to slide on the inner side of the slide guide bar 83, and the baffle 82 no longer blocks the filter screen on the bottom side of the filter box 4, so that the waste sediment on the bottom side of the filter box 4 can be discharged through the filter screen to the bottom box 81 for collection, thereby achieving the purpose of convenient cleaning.
