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

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figures 1 to 10As shown, a rural domestic sewage denitrification device described in an embodiment of the present invention includes a cylinder 1, a support plate 4 is fixedly installed on the outer wall of the cylinder 1, a liquid cylinder 7 is fixedly installed on the bottom of the cylinder 1, and a flow blocking component is arranged inside the liquid cylinder 7. The flow blocking component is used to block the flow of sewage. A plurality of material receiving boxes 3 are fixedly installed on the top of the support plate 4, and a flow pipe 301 is fixedly installed between the plurality of material receiving boxes 3 and the cylinder 1. A feeding component is arranged outside the plurality of flow pipes 301, and the feeding component is used to feed the liquid in the cylinder 1. Denitrifier, a slag box 2 is fixedly installed on the outer wall of the cylinder 1, a stirring assembly is arranged inside the cylinder 1, the stirring assembly is used to stir and mix the denitrifier and sewage, a water vibration assembly is arranged inside the cylinder 1, the water vibration assembly includes an upper leaking plate 8, the water vibration assembly is used to drive the upper leaking plate 8 to shake the plastic bag, a slag throwing assembly is arranged inside the cylinder 1, the slag throwing assembly is used to throw the shaken plastic bag from the cylinder 1 into the slag box 2, the slag throwing assembly is placed above the water vibration assembly, and the stirring assembly is placed below the water vibration assembly;

[0040] Because plastic bags are airtight and waterproof, these properties will cause the plastic bags to float part of the sewage when it flows, resulting in incomplete sewage circulation;

[0041] 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 continuous stirring of the stirring component, thereby accelerating the denitrification rate of the sewage. When the stirring component stirs the sewage, the water vibration component drives the upper leak plate 8 to shake the plastic bag, so that the plastic bag in the sewage is shaken and thrown, thereby shaking the sewage floating on the plastic bag down, avoiding the sewage from 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. When the sewage floating in the plastic bag is shaken and thrown down, the slag throwing component throws the shaken plastic bag from the cylinder 1 into the slag box 2, thereby The plastic bag is taken out from the cylinder 1 to prevent the plastic bag from being retained in the cylinder 1 and causing accumulation. When the plastic bag is thrown into the slag box 2 by the slag throwing assembly, the flow-blocking assembly in the liquid cylinder 7 is opened, and the sewage mixed with the denitrifier in the cylinder 1 will flow from the cylinder 1 into the liquid 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. It should be noted that the plastic bag described in this scheme is only a phenomenon. The slag throwing assembly and the water vibration assembly in this device can operate on a variety of hard objects and substances with water-carrying properties in sewage, such as plastic soup spoons used in rural banquets, facial masks left over from cleansing, etc.

[0042] like Figures 3 to 5As shown, the stirring assembly includes a chassis 9, the chassis 9 is fixedly mounted on the bottom of the inner wall of the liquid cylinder 7, the output end of the liquid cylinder 7 is fixedly mounted with a screw shaft 702, the top of the screw shaft 702 is fixedly mounted with a rotating shaft 901, and the outer wall of the rotating shaft 901 is fixedly mounted with a plurality of stirring plates 12;

[0043] When sewage enters into 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. 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.

[0044] like Figures 9 and 10 As shown, 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, the inner wall of the liquid-setting cylinder 7 is slidably connected with a disc 703, the inner wall of the disc 703 is slidably connected to the outer wall of the chassis 9, a plurality of pressure-bearing springs 705 are arranged between the bottom of the disc 703 and the inner wall of the liquid-setting cylinder 7, a water blocking disc 704 is fixedly installed on the top of the disc 703, and 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 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 to move downward, and the disc 703 will pull the water blocking disc 704 to slide out from the inner wall of the bottom end of the cylinder 1. The mixed sewage placed in the cylinder 1 will flow from the gap between the cylinder 1 and the liquid cylinder 7 into the liquid cylinder 7 to perform the liquid flow operation. The industry plays the role of taking out sewage from the cylinder 1 and providing space for the next mixing of sewage and denitrification agent. The pressure spring 705 is arranged so that when the liquid in the liquid cylinder 7 flows out, the chassis 9 reverses to drive the pressure plate 701 to reset, and the disc 703 will lose the extrusion thrust. The disc 703 will reset under the elastic thrust of the pressure spring 705, so that the water blocking disc 704 is moved back to the bottom of the cylinder 1 to block the flow and play a role in resetting. It should be noted here that the elastic supporting force of the pressure spring 705 is greater than the gravity of the sewage in the cylinder 1, and the screw length of the screw shaft 702 needs to be calculated based on actual measurements.

When the pressure rod 11 rotates, the pressure rod 11 will squeeze the blocking plate 303 to slide in the rectangular block 304 and the flow pipe 301. When the blocking plate 303 is fully pressed and slides into the rectangular block 304, the denitrifier in the feeding box 3 will slide out from the sliding port on the blocking plate 303, and finally enter the cylinder 1 through the flow pipe 301. Through the continuous rotation of the pressure rod 11, the denitrifiers in multiple feeding boxes 3 will be intermittently added to the cylinder 1, which plays a role in intermittently adding denitrifiers to the sewage. Through the continuous stirring of the stirring plate 12, it is ensured that the sewage and the denitrifier can be fully mixed, while reducing the use of the denitrifier, avoiding waste caused by excessive use of the denitrifier.

[0049] When the pressure rod 11 rotates and loses contact with the blocking plate 303, the blocking plate 303 will be reset under the action of the elastic thrust of the reset spring 305, so that when the pressure rod 11 is not in contact with the blocking plate 303, the blocking plate 303 will be reset to block the denitrifier in the material box 3, thereby resetting and blocking the denitrifier, and cooperating with the intermittent squeezing of the blocking plate 303 by the pressure rod 11, the effect of intermittently adding the denitrifier is achieved.

[0051] 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, the lower leakage plate 801 will drive the upper leakage plate 8 to rotate together through the setting of the sliding rod 803. When the upper leakage plate 8 rotates synchronously with the lower leakage plate 801, the upper leakage plate 8 will drive the convex rod 1 802 to rotate on the inner wall of the lower leakage plate 801. Through the limiting setting of the convex rod 2 805 in the shaft box 10, the bottom end of the convex rod 1 802 will slide and rotate with the top of the convex rod 2 805. Through the convex setting of the convex rod 2 805, the convex rod 1 802 will drive the upper leakage plate 8 to move upward. When the top of the second rod 805 slides down, the upper leak plate 8 will be reset by the elastic pulling of the return plate spring 804. Through the continuous rotation of the pressure rod 11, it can be achieved that when the lower leak plate 801 and the upper leak plate 8 rotate, the upper leak plate 8 will vibrate on the top of the lower leak plate 801, thereby driving the plastic bag, plastic soup spoon, etc. placed on the top of the upper leak plate 8 to vibrate, thereby separating the sewage floating on the surface or inside of the plastic bag, plastic soup spoon, etc., and playing the role of vibrating and removing the sewage from the surface or inside of the plastic bag, plastic soup spoon, etc. It should be noted here that the distance that the upper leak plate 8 moves up at the top of the lower leak plate 801 is less than the length of the sliding rod 803.

[0052] like Figures 4 to 6 As shown, a plurality of slag sliding openings 204 are provided between the cylinder 1 and the inner wall of the slag box 2, and the plurality of slag sliding openings 204 are rectangular in shape;

[0053] During operation, the slag sliding port 204 is provided so that when the plastic bags, plastic soup spoons, etc. in the cylinder 1 are shaken and swung, the slag sliding port 204 facilitates the slag throwing assembly to throw the plastic bags, plastic soup spoons, etc. out of the cylinder 1 from the slag sliding port 204, thereby providing a path for the plastic bags, plastic soup spoons, etc. to be thrown out.

[0054] like Figures 4 to 6 As shown, the slag-sweeping assembly includes a liquid blocking ring 202, a telescopic cylinder 201 is fixedly installed on the outer wall of the slag box 2, the output end of the telescopic 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 box 2, and the liquid blocking ring 202 can block multiple slag sliding openings 204;

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

[0056] like Figure 5 to Figure 6 As shown, a slag separator 203 is fixedly installed on the top of the upper leaking plate 8, and multiple rods on the slag separator 203 are arc-shaped, and one end of the multiple rods is slidably connected to the inner wall of the cylinder 1;

[0057] When working, the slag separator 203 is arranged to divide the top of the upper leakage plate 8 into multiple small inner cavities to prevent the plastic bags, plastic soup spoons, etc. from swinging irregularly when being thrown out of the cylinder 1 and unable to be thrown out of the cylinder 1, thereby playing a limiting role.

[0058] like Figure 1 to Figure 2 As shown, a liquid inlet is fixedly installed on the top of the cylinder 1, a butterfly valve 6 is fixedly installed on the outer wall of the liquid inlet, and a discharge valve 5 is fixedly installed on the outer wall of the liquid cylinder 7;

[0059] When it is necessary to introduce sewage into the cylinder 1, the sewage will enter the cylinder 1 by controlling the butterfly valve 6 to open. When the sewage reaches a certain mass, the butterfly valve 6 is controlled to close to control the sewage flow rate. When the sewage mixed with the denitrification agent completely enters the liquid cylinder 7, the unloading valve 5 is controlled to open, and the sewage in the liquid cylinder 7 will be discharged from the liquid cylinder 7, thereby 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 blocking plate 303 to slide in the rectangular block 304 and the flow pipe 301. When the blocking plate 303 is fully pressed and slides into the rectangular block 304, the denitrifier in the receiving box 3 will slide out from the sliding port on the blocking plate 303, and finally enter the cylinder 1 through the flow pipe 301. Through the continuous rotation of the pressure rod 11, the denitrifiers in multiple receiving boxes 3 will be intermittently added to the cylinder 1, which plays a role in intermittently adding denitrifiers to the sewage. Through the continuous stirring of the stirring plate 12, it is ensured that the sewage and the denitrifier can be fully mixed, while reducing the use of the denitrifier, avoiding waste caused by excessive use of the denitrifier;

[0064] When the pressure rod 11 rotates and loses contact with the blocking plate 303, the blocking plate 303 will be reset under the action of the elastic thrust of the reset spring 305, so that when the pressure rod 11 is not in contact with the blocking plate 303, the blocking plate 303 is reset to block the denitrifier in the receiving box 3, playing the role of resetting and blocking the denitrifier, and cooperating with the intermittent squeezing of the blocking plate 303 by the pressure rod 11, the denitrifier is intermittently added.

[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, the lower leakage plate 801 will drive the upper leakage plate 8 to rotate together through the setting of the sliding rod 803. When the upper leakage plate 8 rotates synchronously with the lower leakage plate 801, the upper leakage plate 8 will drive the protruding rod 1 802 to rotate on the inner wall of the lower leakage plate 801. Through the limiting setting of the protruding rod 2 805 in the shaft box 10, the bottom end of the protruding rod 1 802 will slide and rotate with the top of the protruding rod 2 805. Through the convex setting of the protruding rod 2 805, the protruding rod 1 802 will drive the upper leakage plate 8 When the plate 8 moves upward, when the bottom end of the protruding rod 1 802 slides down from the top of the protruding rod 2 805, the upper plate 8 is reset by the elastic pull of the return plate spring 804. By continuously rotating the pressure rod 11, the upper plate 8 can be vibrated on the top of the lower plate 801 while the lower plate 801 and the upper plate 8 rotate, thereby driving the plastic bag, plastic spoon, etc. placed on the top of the upper plate 8 to vibrate, thereby separating the sewage floating on the surface or inside thereof, and playing the role of vibrating and removing the sewage from the surface or inside of the plastic bag, plastic spoon, etc.;

[0066] During operation, the slag sliding port 204 is provided so that when the plastic bag, plastic spoon, etc. in the cylinder 1 are shaken and shaken, the slag sliding port 204 facilitates the slag shaking assembly to shake the plastic bag, plastic spoon, etc. out of the cylinder 1 from the slag sliding port 204, thereby providing a path for the plastic bag, plastic spoon, etc. to be shaken out;

[0067] By setting the system control, when the pressure plate 701 moves three quarters on the screw shaft 702, the system controls the telescopic cylinder 201 to drive the liquid blocking ring 202 to move in the slag box 2, so that the liquid blocking ring 202 is opened at the slag sliding opening 204, and the plastic bags, plastic soup spoons, etc. placed on the top of the upper leakage plate 8 will be thrown into the slag box 2 from the slag sliding opening 204 through the rotation and swinging of the upper leakage plate 8 and the lower leakage plate 801, so as to realize the removal of the plastic bags, plastic soup spoons, etc. from the cylinder 1, and prevent the plastic bags, plastic soup spoons, etc. from accumulating on the top of the upper leakage plate 8 to cause blockage;

[0068] When working, the slag separator 203 is set to divide the top of the upper leaking plate 8 into a plurality of small inner cavities to prevent the plastic bags, plastic spoons, etc. from swinging irregularly when being thrown out of the cylinder 1, and cannot be thrown out of the cylinder 1, thus playing a role of limiting;

[0069] When it is necessary to introduce sewage into the cylinder 1, the sewage will enter the cylinder 1 by controlling the butterfly valve 6 to open. When the sewage reaches a certain mass, the butterfly valve 6 is controlled to close to control the sewage flow rate. When the sewage mixed with the denitrification agent completely enters the liquid cylinder 7, the unloading valve 5 is controlled to open, and the sewage in the liquid cylinder 7 will be discharged from the liquid cylinder 7, thereby discharging the denitrified sewage.
