Description

Technical Field

[0001] The invention belongs to the technical field of rural domestic sewage treatment, in particular to a rural domestic sewage denitrification device. Background Art

[0002] Rural domestic sewage refers to various wastewater generated by rural residents in their daily lives, including kitchen water, laundry water, bathing water, and toilet drainage, etc. These sewage are direct products of rural residents' daily activities.

[0003] Rural domestic sewage denitrification equipment refers to a device specifically used to treat nitrogen in rural domestic sewage. These devices use physical, chemical or biological methods to remove or transform nitrogen-containing compounds (such as ammonia nitrogen, nitrate nitrogen, etc.) in sewage, reducing the nitrogen content in sewage to a level that meets discharge standards or reuse standards.

[0004] A Chinese patent with publication number CN118724283A discloses a denitrification device for rural domestic sewage, including sewage impacting multiple force-bearing blades to drive the force-bearing rods to rotate, the force-bearing rods drive the eccentric wheel to rotate, the eccentric wheel squeezes the force-bearing plate to move, the force-bearing plate drives the sliding rod to move vertically, the sliding rod drives the sealing ball to move upward, the sealing ball leaves the leak hole, and the seal of the leak hole is released to allow ammonia oxidizing bacteria to fall into the NH3 denitrification box. With the entry of sewage, the purpose of automatic bacteria addition is achieved, and denitrification treatment is carried out by relying on different fungi in succession to improve the denitrification effect.

[0005] In daily life, some small plastic bags and non-degradable materials are flushed into the sewer along with kitchen garbage, toilet garbage, etc., and enter the domestic sewage system. For example, when people clean up the garbage in the kitchen sink, they accidentally flush down the plastic bag fragments with food residues, and these plastic bags will become part of the domestic sewage.

[0006] In domestic sewage, plastic bags may float on the surface of sewage in the form of fragments, or they may be suspended in the water due to the flow of sewage. Some plastic bags may also be entangled in other debris in the pipe or be trapped in the sewage grille, thereby blocking the sewage pipe and the components of the sewage treatment equipment. If plastic bags cause accumulation, the water flow area of ​​the grille will be reduced, resulting in the sewage not being able to pass smoothly, and may even cause sewage overflow. In addition, because plastic bags are sealed and waterproof, these characteristics cause the plastic bags to float part of the sewage when it flows, resulting in incomplete circulation of the sewage, and the sewage cannot be fully denitrified.

[0007] To this end, the present invention provides a rural domestic sewage denitrification device. Summary of the invention

[0008] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0009] The technical solution adopted by the present invention to solve its technical problems is as follows: A rural domestic sewage denitrification device described in the present invention includes a cylinder body. A support frame plate is fixedly installed on the outer wall of the cylinder body. A liquid placement cylinder is fixedly installed at the bottom of the cylinder body. A flow blocking component is arranged inside the liquid placement cylinder, and the flow blocking component is used to block the sewage. A plurality of material receiving boxes are fixedly installed on the top of the support frame plate. Flow pipes are fixedly installed between the plurality of material receiving boxes and the cylinder body. Feeding components are arranged outside the plurality of flow pipes, and the feeding components are used to put denitrifying agents into the cylinder body. A slag placement box is fixedly installed on the outer wall of the cylinder body. A stirring component is arranged inside the cylinder body, and the stirring component is used to stir and mix the denitrifying agent and the sewage. A water vibrating component is arranged inside the cylinder body. The water vibrating component includes an upper leakage plate, and the water vibrating component is used to drive the upper leakage plate to vibrate the plastic bag. A slag throwing component is arranged inside the cylinder body, and the slag throwing component is used to throw the vibrated plastic bag from the cylinder body into the slag placement box. The slag throwing component is placed above the water vibrating component, and the stirring component is placed below the water vibrating component;

[0010] By introducing the sewage into the cylinder body, then starting the stirring component to stir the sewage. While stirring, the feeding component puts the denitrifying agent in the material receiving box into the cylinder body. Through continuous stirring by the stirring component, the denitrifying agent and the sewage come into contact with each other and are mixed, accelerating the denitrification speed of the sewage. While the stirring component stirs the sewage, the water vibrating component drives the upper leakage plate to vibrate the plastic bag, causing the plastic bag in the sewage to vibrate and shake, so as to shake off the sewage floating on the plastic bag, preventing the sewage from remaining on the plastic bag and unable to fall into the cylinder body to mix with the denitrifying agent, so that the sewage can be fully and completely mixed with the denitrifying agent. When the sewage floating in the plastic bag is shaken off, the slag throwing component throws the vibrated plastic bag from the cylinder body into the slag placement box, thereby taking out the plastic bag from the cylinder body and preventing the plastic bag from remaining in the cylinder body and causing accumulation. When the plastic bag is thrown into the slag placement box by the slag throwing component, at this time, the flow blocking component in the liquid placement cylinder is opened, and the sewage that has been mixed with the denitrifying agent in the cylinder body will flow from the cylinder body into the liquid placement cylinder, providing space for the next mixing of sewage and denitrifying agent. Thus, the device operation is completed, and the denitrification treatment of the sewage is completed. By repeating the above process in sequence, the denitrification operation of sewage and denitrifying agent can be carried out cyclically.

[0011] Preferably, the stirring assembly includes a chassis fixedly installed at the bottom of the inner wall of the liquid storage cylinder. A screw shaft is fixedly installed at the output end of the liquid storage cylinder. A rotating shaft is fixedly installed at the top of the screw shaft. A plurality of stirring plates are fixedly installed on the outer wall of the rotating shaft. When sewage enters the cylinder, the chassis drives the rotating shaft to rotate through the screw shaft. When the rotating shaft rotates, the rotating shaft drives the stirring plates to rotate. The denitrifying agent in the dosing box is intermittently put into the cylinder through the dosing assembly. The rotating shaft drives the stirring plates to stir the two, so that the two can be fully mixed, playing the role of stirring and mixing the denitrifying agent and sewage.

[0012] Preferably, the flow blocking assembly includes a pressure plate. The inner wall of the pressure plate is threadedly connected to the outer wall of the screw shaft. A disc is slidably connected to the inner wall of the liquid storage cylinder. The inner wall of the disc is slidably connected to the outer wall of the chassis. A plurality of pressure-bearing springs are arranged between the bottom of the disc and the inner wall of the liquid storage cylinder. A water-blocking disc is fixedly installed at the top of the disc. The outer wall of the water-blocking disc can be slidably connected to the inner wall of the cylinder. When the sewage and the denitrifying agent are stirred and mixed, the chassis will drive the screw shaft to rotate continuously. Through threaded transmission, the screw shaft will drive the pressure plate to move downward. When the pressure plate moves downward and contacts the disc, the mixing and stirring of the sewage and the denitrifying agent in the cylinder are completed at this time. Through the continuous downward movement of the pressure plate, the pressure plate will push the disc to squeeze the pressure-bearing springs downward. The disc will pull the water-blocking disc out of the inner wall of the bottom end of the cylinder, and the mixed sewage in the cylinder will flow into the liquid storage cylinder through the gap between the cylinder and the liquid storage cylinder, performing a liquid flow operation, playing the role of taking out the sewage from the cylinder and providing space for the next mixing of sewage and denitrifying agent. The setting of the pressure-bearing springs is that when the liquid in the liquid storage cylinder flows out, the chassis rotates in reverse to drive the pressure plate to reset. The disc will lose the extrusion thrust, and the disc will reset under the elastic thrust of the pressure-bearing springs, so that the water-blocking disc will move back to the bottom of the cylinder again to block the flow, playing the role of resetting.

[0013] Preferably, the dosing assembly includes a blocking plate slidably connected to the inner wall of the material flow pipe. A rectangular block is fixedly installed at the top of the material flow pipe. The outer wall of the blocking plate is slidably connected to the inner wall of the rectangular block. A material sliding port is opened on the inner wall of the blocking plate. Pressing rods are symmetrically and fixedly installed on the outer wall of the rotating shaft. The bottom ends of the two pressing rods can both be slidably connected to the top of the blocking plate. The bottom ends of the two pressing rods and the top end of the blocking plate are all inclined sliding surfaces. When the rotating shaft drives the stirring plates to rotate, the rotating shaft also drives the pressing rods to rotate. When the pressing rods rotate, the pressing rods will squeeze the blocking plate to slide in the rectangular block and the material flow pipe. When the blocking plate is completely pressed and slides into the rectangular block, the denitrifying agent in the dosing box will slide out from the material sliding port on the blocking plate and finally enter the cylinder through the material flow pipe. Through the continuous rotation of the pressing rods, the denitrifying agent in multiple dosing boxes will be intermittently put into the cylinder, playing the role of intermittently putting the denitrifying agent into the sewage. Through the continuous stirring of the stirring plates, while ensuring the full mixing of the sewage and the denitrifying agent, the use of the denitrifying agent can be reduced, avoiding waste caused by excessive use of the denitrifying agent.

[0014] Preferably, a groove box is fixedly installed at the top of the support plate. The outer wall of the blanking plate is slidably connected to the inner wall of the groove box. A plurality of return springs are arranged between the bottom of the blanking plate and the inner wall of the groove box. When the pressing rod rotates and loses contact with the blanking plate, the blanking plate will be reset under the elastic thrust of the return springs. Thus, when the pressing rod is not in contact with the blanking plate, the blanking plate is reset to block the denitrifying agent in the material receiving box, playing the role of resetting and blocking the denitrifying agent. Cooperating with the intermittent extrusion of the pressing rod on the blanking plate, the intermittent feeding of the denitrifying agent is realized.

[0015] Preferably, the water vibrating assembly further includes a shaft box. The shaft box is fixedly installed at the middle position inside the cylinder body. One end of the rotating shaft is rotatably connected to the bottom of the shaft box. A lower leakage plate is rotatably connected to the top of the shaft box. A plurality of sliding rods are fixedly installed at the bottom of the upper leakage plate. The outer walls of the plurality of sliding rods are slidably connected to the inner wall of the lower leakage plate. Return plate springs are arranged between the bottoms of the plurality of sliding rods and the inner wall of the lower leakage plate. A first convex rod is fixedly installed at the middle position of the bottom of the upper leakage plate. The outer wall of the first convex rod is rotatably connected to the inner wall of the lower leakage plate. A second convex rod is fixedly installed on the inner wall of the shaft box. The bottom end of the first convex rod is slidably connected to the top of the second convex rod. The bottom end of the first convex rod and the top of the second convex rod are both inclined sliding surfaces. The outer wall of the first convex rod is rotatably connected to the inner wall of the shaft box. Connecting rods are symmetrically and fixedly installed on the outer wall of the lower leakage plate. One ends of the two connecting rods are respectively fixedly connected to the tops of the two pressing rods. When the pressing rod rotates, the pressing rod drives the lower leakage plate to rotate through the connecting rod. When the lower leakage plate rotates, through the arrangement of the sliding rods, the lower leakage plate will drive the upper leakage plate to rotate together. When the upper leakage plate and the lower leakage plate rotate synchronously, the upper leakage plate will drive the first convex rod to rotate inside the lower leakage plate. Through the limiting arrangement of the second convex rod in the shaft box, the bottom end of the first convex rod will slide and rotate with the top of the second convex rod. Through the convex setting of the second convex rod, the first convex rod will drive the upper leakage plate to move upward. When the bottom end of the first convex rod slides down from the top of the second convex rod, the upper leakage plate will be reset under the elastic pulling of the return plate spring. Through the continuous rotation of the pressing rod, when the lower leakage plate and the upper leakage plate rotate, the upper leakage plate vibrates on the top of the lower leakage plate, so as to drive the plastic bags, plastic soup spoons, etc. placed on the top of the upper leakage plate to vibrate and swing, so as to separate the sewage floating on their surfaces or inside from them, playing the role of vibrating and swinging to remove the sewage from the surfaces or inside of the plastic bags, plastic soup spoons, etc.

[0016] Preferably, a plurality of slag sliding openings are formed between the inner walls of the cylinder body and the slag placing box. The plurality of slag sliding openings are rectangular. During operation, the setting of the slag sliding openings is for when the plastic bags, plastic soup spoons, etc. in the cylinder body are vibrated and swung, the slag sliding openings facilitate the slag throwing assembly to throw the plastic bags, plastic soup spoons, etc. out of the inside of the cylinder body from the slag sliding openings, playing the role of providing a path for the plastic bags, plastic soup spoons, etc. to be thrown out.

[0017] Preferably, the slag discharging assembly includes a liquid blocking ring. A telescopic cylinder is fixedly installed on the outer wall of the slag placing box. The output end of the telescopic cylinder is fixedly connected to the top of the liquid blocking ring. The inner ring wall of the liquid blocking ring is slidably connected to the inner wall of the slag placing box. The liquid blocking ring can block multiple slag discharging ports. Through system control, when the pressure plate moves three-quarters on the screw shaft, the system controls the telescopic cylinder to drive the liquid blocking ring to move in the slag placing box, so that the liquid blocking ring opens at the slag discharging port. Plastic bags, plastic spoons, etc. placed on the top of the upper leakage plate will be thrown into the slag placing box through the rotation and shaking of the upper leakage plate and the lower leakage plate from the slag discharging port, thus realizing the removal of plastic bags, plastic spoons, etc. from the cylinder body and preventing plastic bags, plastic spoons, etc. from accumulating on the top of the upper leakage plate and causing blockage.

[0018] Preferably, a slag separating member is fixedly installed on the top of the upper leakage plate. The multiple rod bodies on the slag separating member are arc-shaped. One end of the multiple rod bodies is slidably connected to the inner wall of the cylinder body. During operation, the setting of the slag separating member is to divide the top of the upper leakage plate into multiple small inner cavities to prevent plastic bags, plastic spoons, etc. from making irregular shaking when being thrown out of the cylinder body and being unable to be thrown out of the cylinder body, playing a role of limiting.

[0019] Preferably, a liquid inlet is fixedly installed on the top of the cylinder body. A butterfly valve is fixedly installed on the outer wall of the liquid inlet. A discharge valve is fixedly installed on the outer wall of the liquid placing cylinder. When it is necessary to introduce sewage into the cylinder body, by controlling the opening of the butterfly valve, the sewage will enter the cylinder body. When the sewage reaches a certain mass, control the butterfly valve to close to control the sewage flow. When the sewage mixed with the denitrifying agent completely enters the liquid placing cylinder, control the discharge valve to open, and the sewage placed in the liquid placing cylinder will be discharged from the liquid placing cylinder to discharge the denitrified sewage.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. For the rural domestic sewage denitrification equipment described in the present invention, when the upper leakage plate and the lower leakage plate rotate synchronously, the upper leakage plate drives the first convex rod to rotate on the inner wall of the lower leakage plate. Through the limit setting of the second convex rod in the shaft box, the bottom end of the first convex rod will slide and rotate with the top of the second convex rod, and the first convex rod will drive the upper leakage plate to move upward. When the bottom end of the first convex rod slides down from the top of the second convex rod, through the elastic pull of the return plate spring, the upper leakage plate will be reset. Through the continuous rotation of the pressure rod, when the lower leakage plate and the upper leakage plate rotate, the upper leakage plate vibrates on the top of the lower leakage plate, so as to drive the plastic bags, plastic spoons, etc. placed on the top of the upper leakage plate to vibrate and swing, so as to separate the sewage floating on the surface or inside of them, playing a role of vibrating and swinging plastic bags, plastic spoons, etc.

[0022] 2. In the denitrification equipment for rural domestic sewage of the present invention, when the rotating shaft drives the stirring plate to rotate, the rotating shaft also drives the pressure rod to rotate. When the pressure rod rotates, the pressure rod will squeeze the material-blocking plate to slide in the rectangular block and the material-flow pipe. When the material-blocking plate is completely pressed and slides into the rectangular block, the denitrifying agent in the material-receiving box will slide out from the material-sliding port on the material-blocking plate and finally enter the cylinder through the material-flow pipe. Through the continuous rotation of the pressure rod, the denitrifying agents in multiple material-receiving boxes will be intermittently put into the cylinder, playing the role of intermittently putting the denitrifying agent into the sewage. Through the continuous stirring of the stirring plate, while ensuring that the sewage and the denitrifying agent can be fully mixed, the use of the denitrifying agent can be reduced, and the waste caused by excessive use of the denitrifying agent can be avoided.

[0023] 3. In the denitrification equipment for rural domestic sewage of the present invention, when the sewage is stirred and mixed with the denitrifying agent, the chassis will drive the screw shaft to rotate continuously. Through screw drive, the screw shaft will drive the pressure plate to move downward. When the pressure plate moves downward and contacts the disc, the mixing and stirring of the sewage and the denitrifying agent in the cylinder are completed at this time. Through the continuous downward movement of the pressure plate, the pressure plate will push the disc to squeeze the pressure-bearing spring downward, and the disc will pull the water-blocking plate out of the inner wall at the bottom end of the cylinder. The mixed sewage in the cylinder will flow into the liquid-placement cylinder from the gap between the cylinder and the liquid-placement cylinder for liquid-flow operation, playing the role of taking out the sewage from the cylinder and providing space for the next mixing of sewage and denitrifying agent.

[0024] 4. In the denitrification equipment for rural domestic sewage of the present invention, through the setting of system control, when the pressure plate moves three-quarters on the screw shaft, the system control drives the telescopic cylinder to drive the liquid-blocking ring to move in the slag-placement box, so that the liquid-blocking ring is opened at the slag-sliding port. Plastic bags, plastic spoons, etc. placed on the top of the upper leakage plate will be thrown into the slag-placement box from the slag-sliding port through the rotational flinging of the upper leakage plate and the lower leakage plate, thus realizing the removal of plastic bags, plastic spoons, etc. from the cylinder and preventing the accumulation of plastic bags, plastic spoons, etc. on the top of the upper leakage plate, causing blockage.

[0025] 5. In the denitrification equipment for rural domestic sewage of the present invention, when the sewage enters the cylinder, the chassis drives the rotating shaft to rotate through the screw shaft. When the rotating shaft rotates, the rotating shaft drives the stirring plate to rotate. Through the feeding assembly, the denitrifying agent in the material-receiving box is intermittently put into the cylinder, and the rotating shaft drives the stirring plate to stir the two, so that the two can be fully mixed, playing the role of stirring and mixing the denitrifying agent and the sewage.

Detailed implementation manners

[0038] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0039] Such as Figures 1 to 10As shown in the figure, a rural domestic sewage denitrification device according to an embodiment of the present invention includes a cylinder body 1. A support frame disk 4 is fixedly installed on the outer wall of the cylinder body 1. A liquid placement cylinder 7 is fixedly installed at the bottom of the cylinder body 1. A flow blocking component is arranged inside the liquid placement cylinder 7, and the flow blocking component is used to block the sewage. A plurality of material receiving boxes 3 are fixedly installed on the top of the support frame disk 4. Flow pipes 301 are fixedly installed between the plurality of material receiving boxes 3 and the cylinder body 1. Feeding components are arranged outside the plurality of flow pipes 301, and the feeding components are used to put denitrifying agents into the cylinder body 1. A slag placement box 2 is fixedly installed on the outer wall of the cylinder body 1. A stirring component is arranged inside the cylinder body 1, and the stirring component is used to stir and mix the denitrifying agents and the sewage. A water vibrating component is arranged inside the cylinder body 1. The water vibrating component includes an upper leakage plate 8, and the water vibrating component is used to drive the upper leakage plate 8 to vibrate the plastic bags. A slag throwing component is arranged inside the cylinder body 1, and the slag throwing component is used to throw the vibrated plastic bags from the cylinder body 1 into the slag placement box 2. The slag throwing component is placed above the water vibrating component, and the stirring component is placed below the water vibrating component;

[0040] Since plastic bags have sealing and waterproof properties, these properties cause plastic bags to hold up a part of the sewage when the sewage is flowing, resulting in incomplete sewage flow;

[0041] By introducing the sewage into the cylinder body 1, then starting the stirring component to stir the sewage, while stirring, the feeding component puts the denitrifying agents in the material receiving box 3 into the cylinder body 1. Through continuous stirring of the stirring component, the denitrifying agents and the sewage come into contact with each other and are mixed, accelerating the denitrification speed of the sewage. When the stirring component stirs the sewage, the water vibrating component drives the upper leakage plate 8 to vibrate the plastic bags, causing the plastic bags in the sewage to vibrate and swing, so as to swing down the sewage held up by the plastic bags, preventing the sewage from staying on the plastic bags and being unable to fall into the cylinder body 1 to mix with the denitrifying agents, so that the sewage can fully and completely mix with the denitrifying agents. When the sewage held up by the plastic bags is swung down, the slag throwing component throws the vibrated plastic bags from the cylinder body 1 into the slag placement box 2, thus taking out the plastic bags from the cylinder body 1 and preventing the plastic bags from staying in the cylinder body 1 and causing accumulation. When the plastic bags are thrown into the slag placement box 2 by the slag throwing component, at this time, the flow blocking component in the liquid placement cylinder 7 is opened, and the sewage that has been mixed with the denitrifying agents in the cylinder body 1 will flow from the cylinder body 1 into the liquid placement cylinder 7, providing space for the next mixing of sewage and denitrifying agents. Thus, the device operation is completed, and the denitrification treatment of the sewage is completed. By repeating the above process in sequence, the denitrification operation of sewage and denitrifying agents can be carried out cyclically. Here, it should be noted that the plastic bags mentioned in this solution are only a way of saying a phenomenon. The slag throwing component and the water vibrating component in this device can operate on various hard objects and substances with water-holding characteristics in the sewage, such as plastic soup spoons used at rural banquets, facial masks left after cleansing, etc.

[0042] Such as Figures 3 to 5As shown in the figure, the stirring assembly includes a chassis 9, which is fixedly installed at the bottom of the inner wall of the liquid storage cylinder 7. The output end of the liquid storage cylinder 7 is fixedly installed with a screw shaft 702. The top end of the screw shaft 702 is fixedly installed with a rotating shaft 901. A plurality of stirring plates 12 are fixedly installed on the outer wall of the rotating shaft 901;

[0043] When sewage enters the cylinder 1, the chassis 9 drives the rotating shaft 901 to rotate through the screw shaft 702. When the rotating shaft 901 rotates, the rotating shaft 901 drives the stirring plates 12 to rotate. The denitrifying agent in the dosing box 3 is intermittently put into the cylinder 1 through the dosing assembly. The rotating shaft 901 drives the stirring plates 12 to stir the two, so that the two can be fully mixed, playing the role of stirring and mixing the denitrifying agent and sewage.

[0044] As Figures 9 to 10 shown in the figure, the flow blocking assembly includes a pressure plate 701. The inner wall of the pressure plate 701 is threadedly connected to the outer wall of the screw shaft 702. A disc 703 is slidably connected to the inner wall of the liquid storage cylinder 7. The inner wall of the disc 703 is slidably connected to the outer wall of the chassis 9. A plurality of bearing springs 705 are arranged between the bottom of the disc 703 and the inner wall of the liquid storage cylinder 7. A water blocking disc 704 is fixedly installed on the top of the disc 703. The outer wall of the water blocking disc 704 can be slidably connected to the inner wall of the cylinder 1;

[0045] When the sewage and the denitrifying agent are stirred and mixed, the chassis 9 will drive the screw shaft 702 to rotate continuously. Through screw drive, the screw shaft 702 will drive the pressure plate 701 to move downward. When the pressure plate 701 moves downward and contacts the disc 703, the mixing and stirring of the sewage and the denitrifying agent in the cylinder 1 are completed at this time. Through the continuous downward movement of the pressure plate 701, the pressure plate 701 will push the disc 703 to squeeze the bearing spring 705 downward, and the disc 703 will pull the water blocking disc 704 out of the bottom inner wall of the cylinder 1. The mixed sewage in the cylinder 1 will flow into the liquid storage cylinder 7 from the gap between the cylinder 1 and the liquid storage cylinder 7, performing a liquid flow operation, playing the role of taking out the sewage from the cylinder 1, providing space for the next mixing of sewage and denitrifying agent. The setting of the bearing spring 705 is for when the liquid in the liquid storage cylinder 7 flows out, the chassis 9 rotates in reverse to drive the pressure plate 701 to reset. The disc 703 will lose the extrusion thrust, and the disc 703 will reset under the elastic thrust of the bearing spring 705, so that the water blocking disc 704 will move back to the bottom of the cylinder 1 again to block the flow, playing a reset role. It should be noted here that the elastic supporting force of the bearing spring 705 is greater than the gravity of the sewage in the cylinder 1, and the pitch length of the screw shaft 702 needs to be obtained according to actual measurement.

[0046] As Figures 5 to 9As shown, the feeding component includes a blanking plate 303, which is slidably connected to the inner wall of the material flow pipe 301. A rectangular block 304 is fixedly installed at the top of the material flow pipe 301, and the outer wall of the blanking plate 303 is slidably connected to the inner wall of the rectangular block 304. A material sliding port is provided on the inner wall of the blanking plate 303. Symmetrically fixed on the outer wall of the rotating shaft 901 are pressure rods 11, and the bottom ends of both pressure rods 11 can be slidably connected to the top of the blanking plate 303. The bottom ends of both pressure rods 11 and the top end of the blanking plate 303 are inclined sliding surfaces;

[0047] When the rotating shaft 901 drives the stirring plate 12 to rotate, the rotating shaft 901 also drives the pressure rods 11 to rotate. When the pressure rods 11 rotate, the pressure rods 11 will squeeze the blanking plate 303 to slide within the rectangular block 304 and the material flow pipe 301. When the blanking plate 303 is completely pressed and slides into the rectangular block 304, the denitrifying agent in the material receiving box 3 will slide out from the material sliding port on the blanking plate 303 and finally enter the cylinder 1 through the material flow pipe 301. Through the continuous rotation of the pressure rods 11, the denitrifying agent in multiple material receiving boxes 3 will be intermittently put into the cylinder 1, playing the role of intermittently putting the denitrifying agent into the sewage. Through the continuous stirring of the stirring plate 12, it can ensure that the sewage and the denitrifying agent are fully mixed while reducing the use of the denitrifying agent and avoiding waste caused by excessive use of the denitrifying agent.

[0048] As Figures 8 to 9 shown, a groove box 302 is fixedly installed at the top of the support plate 4, and the outer wall of the blanking plate 303 is slidably connected to the inner wall of the groove box 302. A plurality of return springs 305 are provided between the bottom of the blanking plate 303 and the inner wall of the groove box 302;

[0049] When the pressure rods 11 rotate and lose contact with the blanking plate 303, the blanking plate 303 will be reset under the elastic thrust of the return springs 305. Thus, when the pressure rods 11 are not in contact with the blanking plate 303, the blanking plate 303 is reset to block the denitrifying agent in the material receiving box 3, playing the role of resetting and blocking the denitrifying agent. Cooperating with the intermittent extrusion of the blanking plate 303 by the pressure rods 11, the role of intermittently putting the denitrifying agent is realized.

[0050] As Figures 6 to 8As shown in the figure, the water shaking assembly further includes a shaft box 10. The shaft box 10 is fixedly installed at the middle position inside the cylinder body 1. One end of the rotating shaft 901 is rotatably connected to the bottom of the shaft box 10. A lower leakage plate 801 is rotatably connected to the top of the shaft box 10. A plurality of sliding rods 803 are fixedly installed at the bottom of the upper leakage plate 8. The outer walls of the plurality of sliding rods 803 are slidably connected to the inner wall of the lower leakage plate 801. A return plate spring 804 is arranged between the bottom of each of the plurality of sliding rods 803 and the inner wall of the lower leakage plate 801. A first convex rod 802 is fixedly installed at the middle position of the bottom of the upper leakage plate 8. The outer wall of the first convex rod 802 is rotatably connected to the inner wall of the lower leakage plate 801. A second convex rod 805 is fixedly installed on the inner wall of the shaft box 10. The bottom end of the first convex rod 802 is slidably connected to the top of the second convex rod 805. The bottom end of the first convex rod 802 and the top of the second convex rod 805 are both inclined sliding surfaces. The outer wall of the first convex rod 802 is rotatably connected to the inner wall of the shaft box 10. Connecting rods 13 are symmetrically and fixedly installed on the outer wall of the lower leakage plate 801. One ends of the two connecting rods 13 are respectively fixedly connected to the tops of the two pressing rods 11;

[0051] When the pressing rod 11 rotates, the pressing rod 11 drives the lower leakage plate 801 to rotate through the connecting rod 13. When the lower leakage plate 801 rotates, due to the arrangement of the sliding rods 803, the lower leakage plate 801 will drive the upper leakage plate 8 to rotate together. When the upper leakage plate 8 rotates synchronously with the lower leakage plate 801, the upper leakage plate 8 will drive the first convex rod 802 to rotate inside the inner wall of the lower leakage plate 801. Through the limiting arrangement of the second convex rod 805 in the shaft box 10, the bottom end of the first convex rod 802 will slide and rotate on the top of the second convex rod 805. Due to the convex setting of the second convex rod 805, the first convex rod 802 will drive the upper leakage plate 8 to move upward. When the bottom end of the first convex rod 802 slides down from the top of the second convex rod 805, through the elastic pull of the return plate spring 804, the upper leakage plate 8 will be reset. Through the continuous rotation of the pressing rod 11, it can be realized that when the lower leakage plate 801 and the upper leakage plate 8 rotate, the upper leakage plate 8 vibrates on the top of the lower leakage plate 801, thereby driving the plastic bags, plastic soup spoons, etc. placed on the top of the upper leakage plate 8 to vibrate and swing, so as to separate the sewage floating on their surfaces or inside from them, playing the role of vibrating and swinging to remove the sewage from the surfaces or inside of the plastic bags, plastic soup spoons, etc. It should be noted here that the upward movement distance of the upper leakage plate 8 on the top of the lower leakage plate 801 is less than the length of the sliding rod 803.

[0052] As Figures 4 to 6 shown, a plurality of slag sliding openings 204 are formed between the inner walls of the cylinder body 1 and the slag placing box 2. The plurality of slag sliding openings 204 are rectangular;

[0053] During operation, the setting of the slag sliding opening 204 is for when the plastic bags, plastic soup spoons, etc. in the cylinder body 1 are vibrated and swung, the slag sliding opening 204 facilitates the slag throwing assembly to throw the plastic bags, plastic soup spoons, etc. out of the inside of the cylinder body 1 from the slag sliding opening 204, playing the role of providing a path for the plastic bags, plastic soup spoons, etc. to be thrown out.

[0054] As shown Figures 4 to 6 in the figure, the slag-dumping assembly includes a liquid-blocking ring 202. An expansion cylinder 201 is fixedly installed on the outer wall of the slag-containing tank 2. The output end of the expansion cylinder 201 is fixedly connected to the top of the liquid-blocking ring 202. The inner ring wall of the liquid-blocking ring 202 is slidably connected to the inner wall of the slag-containing tank 2. The liquid-blocking ring 202 can block a plurality of slag-sliding ports 204;

[0055] By setting system control, when the pressure plate 701 moves three-quarters on the screw shaft 702, the system controls the expansion cylinder 201 to drive the liquid-blocking ring 202 to move in the slag-containing tank 2, so that the liquid-blocking ring 202 is opened at the slag-sliding port 204. Plastic bags, plastic soup spoons, etc. placed on the top of the upper leakage plate 8 will be thrown into the slag-containing tank 2 from the slag-sliding port 204 through the rotational flinging of the upper leakage plate 8 and the lower leakage plate 801, thereby realizing the removal of plastic bags, plastic soup spoons, etc. from the cylinder body 1 and preventing plastic bags, plastic soup spoons, etc. from accumulating on the top of the upper leakage plate 8 and causing blockage.

[0056] As shown Figures 5 to 6 in the figure, a slag-separating member 203 is fixedly installed on the top of the upper leakage plate 8. A plurality of rod bodies on the slag-separating member 203 are arc-shaped, and one end of the plurality of rod bodies is slidably connected to the inner wall of the cylinder body 1;

[0057] During operation, the slag-separating member 203 is provided to divide the top of the upper leakage plate 8 into a plurality of small inner cavities, preventing plastic bags, plastic soup spoons, etc. from making irregular flinging when being thrown out of the cylinder body 1 and unable to be thrown out of the cylinder body 1, playing a role of limiting.

[0058] As shown Figures 1 to 2 in the figure, a liquid inlet is fixedly installed on the top of the cylinder body 1. A butterfly valve 6 is fixedly installed on the outer wall of the liquid inlet. A drain valve 5 is fixedly installed on the outer wall of the liquid-containing cylinder 7;

[0059] When it is necessary to introduce sewage into the cylinder body 1, by controlling the opening of the butterfly valve 6, the sewage will enter the cylinder body 1. When the sewage reaches a certain mass, control the butterfly valve 6 to close, playing a role of controlling the sewage flow. When the sewage mixed with the denitrifying agent completely enters the liquid-containing cylinder 7, control the drain valve 5 to open, and the sewage placed in the liquid-containing cylinder 7 will be discharged from the liquid-containing cylinder 7, playing a role of discharging the denitrified sewage.

[0060] Working principle: The sewage is passed into the cylinder 1, and then the stirring component is started to stir the sewage. While stirring, the feeding component feeds the denitrifier from the feeding box 3 into the cylinder 1. The denitrifier and the sewage are contacted and mixed by the continuous stirring of the stirring component, which accelerates the denitrification speed of the sewage. When the stirring component stirs the sewage, the water vibration component drives the upper leakage plate 8 to shake the plastic bag, so that the plastic bag in the sewage is shaken, thereby shaking off the sewage floating on the plastic bag, avoiding the sewage being retained on the plastic bag and unable to fall into the cylinder 1 and mix with the denitrifier, so that the sewage can be fully and completely mixed with the denitrifier. Mixing, when the sewage floating in the plastic bag is shaken down, the slag-sweeping component will swing the shaken plastic bag from the cylinder 1 into the slag-setting box 2, so that the plastic bag is taken out of the cylinder 1 to avoid the plastic bag being retained in the cylinder 1 and causing accumulation. When the plastic bag is thrown into the slag-setting box 2 by the slag-sweeping component, the flow-blocking component in the liquid-setting cylinder 7 is opened at this time, and the sewage mixed with the denitrifier in the cylinder 1 will flow from the cylinder 1 into the liquid-setting cylinder 7, providing space for the next mixing of sewage and denitrifier. At this point, the operation of the device is completed, and the denitrification treatment of the sewage is completed. By repeating the above process in sequence, the sewage and the denitrification agent can be denitrified repeatedly.

[0061] When sewage enters the cylinder 1, the chassis 9 drives the rotating shaft 901 to rotate through the screw shaft 702. When the rotating shaft 901 rotates, the rotating shaft 901 drives the stirring plate 12 to rotate, and the denitrification agent in the feeding box 3 is intermittently fed into the cylinder 1 through the feeding assembly. The rotating shaft 901 drives the stirring plate 12 to stir the two, so that the two can be fully mixed, thereby playing the role of stirring and mixing the denitrification agent and sewage;

[0062] When the sewage and the denitrification agent are stirred and mixed, the chassis 9 will drive the screw shaft 702 to rotate continuously. Through the threaded transmission, the screw shaft 702 will drive the pressure plate 701 to move downward. When the pressure plate 701 moves downward and contacts the disc 703, the mixing and stirring of the sewage and the denitrification agent in the cylinder 1 is completed. Through the continuous downward movement of the pressure plate 701, the pressure plate 701 will push the disc 703 to squeeze the pressure spring 705 downward, and the disc 703 will pull the water blocking disc 704 to slide out from the bottom inner wall of the cylinder 1, and the mixed sewage in the cylinder 1 will be discharged from The gap between the cylinder 1 and the liquid-setting cylinder 7 flows into the liquid-setting cylinder 7 to perform the liquid flow operation, which plays the role of taking out the sewage from the cylinder 1 and providing space for the next mixing of sewage and denitrification agent. The pressure spring 705 is set so that when the liquid in the liquid-setting cylinder 7 flows out, the chassis 9 reverses and drives the pressure plate 701 to reset, and the disc 703 loses the extrusion thrust. The disc 703 will reset under the elastic thrust of the pressure spring 705, so that the water blocking disc 704 moves back to the bottom of the cylinder 1 to block the flow and play the role of resetting;

[0063] When the rotating shaft 901 drives the stirring plate 12 to rotate, the rotating shaft 901 also drives the pressure rod 11 to rotate. When the pressure rod 11 rotates, the pressure rod 11 will squeeze the material blocking plate 303 to slide within the rectangular block 304 and the material flow pipe 301. When the material blocking plate 303 is completely pressed and slides into the rectangular block 304, the denitrifying agent in the material receiving box 3 will slide out from the material sliding port on the material blocking plate 303, and finally enter the cylinder body 1 through the material flow pipe 301. Through the continuous rotation of the pressure rod 11, the denitrifying agent in multiple material receiving boxes 3 will be intermittently put into the cylinder body 1, playing the role of intermittently putting the denitrifying agent into the sewage. Through the continuous stirring of the stirring plate 12, while ensuring that the sewage and the denitrifying agent can be fully mixed, the use of the denitrifying agent can be reduced, avoiding waste caused by excessive use of the denitrifying agent;

[0064] When the pressure rod 11 rotates and loses contact with the material blocking plate 303, the material blocking plate 303 will be reset under the elastic thrust of the reset spring 305. Thus, when the pressure rod 11 and the material blocking plate 303 are not in contact, the material blocking plate 303 is reset to block the denitrifying agent in the material receiving box 3, playing the role of resetting and blocking the denitrifying agent. Cooperating with the intermittent extrusion of the pressure rod 11 on the material blocking plate 303, the role of intermittently putting the denitrifying agent is realized;

[0065] When the pressure rod 11 rotates, the pressure rod 11 drives the lower leakage plate 801 to rotate through the connecting rod 13. When the lower leakage plate 801 rotates, through the setting of the sliding rod 803, the lower leakage plate 801 will drive the upper leakage plate 8 to rotate together. When the upper leakage plate 8 rotates synchronously with the lower leakage plate 801, the upper leakage plate 8 will drive the convex rod one 802 to rotate on the inner wall of the lower leakage plate 801. Through the limit setting of the convex rod two 805 in the shaft box 10, the bottom end of the convex rod one 802 will slide and rotate with the top of the convex rod two 805. Through the convex setting of the convex rod two 805, the upper leakage plate 8 will be driven to move upward. When the bottom end of the convex rod one 802 slides down from the top of the convex rod two 805, the upper leakage plate 8 will be reset by the elastic pull of the return plate spring 804. Through the continuous rotation of the pressure rod 11, it can be realized that when the lower leakage plate 801 and the upper leakage plate 8 rotate, the upper leakage plate 8 vibrates on the top of the lower leakage plate 801, thereby driving the plastic bags, plastic soup spoons, etc. placed on the top of the upper leakage plate 8 to vibrate and swing, so as to separate the sewage floating on their surfaces or inside from them, playing the role of vibrating and swinging to remove the sewage from the surfaces or inside of plastic bags, plastic soup spoons, etc.;

[0066] During operation, the setting of the slag sliding port 204 is for when the plastic bags, plastic soup spoons, etc. in the cylinder body 1 are finished vibrating and swinging, the slag sliding port 204 facilitates the slag throwing assembly to throw the plastic bags, plastic soup spoons, etc. out of the inside of the cylinder body 1 from the slag sliding port 204, playing the role of providing a path for the plastic bags, plastic soup spoons, etc. to be thrown out;

[0067] By setting system control, when the pressure plate 701 moves three-quarters on the screw shaft 702, the system control extends and retracts the air cylinder 201 to drive the liquid-blocking ring 202 to move in the slag-containing box 2, so that the liquid-blocking ring 202 is opened at the slag-draining port 204. Plastic bags, plastic soup spoons, etc. placed on the top of the upper leakage plate 8 will be thrown into the slag-containing box 2 from the slag-draining port 204 by the rotational shaking of the upper leakage plate 8 and the lower leakage plate 801, thus realizing the removal of plastic bags, plastic soup spoons, etc. from the cylinder body 1, preventing the accumulation of plastic bags, plastic soup spoons, etc. on the top of the upper leakage plate 8 and causing blockage;

[0068] During operation, the slag-separating member 203 is arranged to divide the top of the upper leakage plate 8 into multiple small inner cavities, preventing the plastic bags, plastic soup spoons, etc. from making irregular shaking when being thrown out of the cylinder body 1 and unable to be thrown out of the cylinder body 1, playing a role in limiting the position;

[0069] When it is necessary to introduce sewage into the cylinder body 1, by controlling the butterfly valve 6 to open, the sewage will enter the cylinder body 1. When the sewage reaches a certain mass, control the butterfly valve 6 to close, playing a role in controlling the sewage flow rate. When the sewage mixed with the denitrifying agent completely enters the liquid-containing cylinder 7, control the discharge valve 5 to open, and the sewage placed in the liquid-containing cylinder 7 will be discharged from the liquid-containing cylinder 7, playing a role in discharging the denitrified sewage.
