Utility Model Content

[0005] After long-term production practice, it was found that when the filter pad is used for too long, a large amount of sludge and impurities will remain inside, which will cause blockage inside the filter pad and shorten the service life of the filter pad.

[0006] In view of the above, the present invention aims to provide a domestic sewage treatment and disinfection device, comprising a tank body; a filter pad fixedly connected to the inner side wall of the tank body; a water spray plate fixedly connected to the bottom of the inner side wall of the tank body; a plurality of circular holes formed on the top of the water spray plate; a water inlet pipe connected to the bottom of the water spray plate; the water inlet pipe and the tank body are interpenetrating; a motor fixedly connected to the top of the tank body; a rotating shaft fixedly connected to the output end of the motor; the rotating shaft and the tank body are interpenetrating and rotatably connected; the rotating shaft and the filter pad are rotatably connected; a plurality of stirring rods fixedly connected to the middle of the rotating shaft; a plurality of first connecting rods provided at the middle of the rotating shaft; a plurality of cleaning rods fixedly connected to the middle of the first connecting rods; the cleaning rods are located at the bottom of the filter pad; the cleaning rods rotate with the first connecting rods under the transmission action of the rotating shaft and clear the inside of the filter pad, thereby reducing sludge and impurities clogged in the filter pad, ensuring that the filter pad can stably filter sewage and extend the service life of the filter pad.

[0007] In one embodiment, a plurality of fixed blocks are fixedly connected to the inner side wall of the tank body; the first connecting rod and the rotating shaft are in a hinged relationship; the first connecting rod and the rotating shaft are connected by a torsion spring; the fixed block and the first connecting rod are correspondingly arranged; the cleaning rod will shake with the squeezing action of the fixed block as the first connecting rod, so that the cleaning rod can clean different depths inside the filter pad, thereby enhancing the cleaning effect of the cleaning rod on the filter pad and further reducing impurities clogging inside the filter pad.

[0008] In one embodiment, a connecting block is fixedly connected to the end of the first connecting rod; the connecting block is a spherical structure; a plurality of balls are rotatably connected to the middle of the connecting block; when the first connecting rod and the fixed block come into contact, the connecting block and the balls will also come into contact with the fixed block, and the balls will rotate under the action of friction, so that the sliding friction between the connecting block and the fixed block is converted into rolling friction, thereby reducing the friction between the fixed block and the connecting block and extending the service life of the fixed block.

[0009] In one embodiment, scrapers are fixedly connected to the ends of adjacent stirring rods; the scrapers are located between the filter pad and the water spray plate; when the stirring rod rotates, the scrapers are driven to rotate together, and when the scrapers rotate, they come into contact with the inner wall of the tank body.

At the same time, when the sliding rod closes this part of the circular hole, the water flow at the remaining circular holes will increase, thereby increasing the speed at which the disinfectant is sprayed out of the circular hole, so that the disinfectant can react with the sewage faster, thereby enhancing the disinfection effect of the device on sewage.

[0011] In one embodiment, a fixing rod is fixedly connected to the middle of the wheel; the fixing rod is an arc-shaped structure; a ball is fixedly connected to the end of the fixing rod; when the wheel contacts the top plate, it will rotate under the action of friction, and the fixing rod and the ball will swing as the wheel rotates.

[0044] In order to reduce the sludge impurities adhering to the inner wall of the tank body 1 and improve the convenience of the device for cleaning the tank body 1, in another embodiment of the present utility model, as Figure 3 As shown, the ends of the adjacent stirring rods 16 are fixedly connected with scrapers 4; the scrapers 4 are located between the filter pad 17 and the water spray plate 12; when the stirring rod 16 rotates, the scrapers 4 are driven to rotate together, and when the scrapers 4 rotate, they come into contact with the inner wall of the tank body 1, and the scrapers 4 clean the inner wall of the tank body 1, thereby reducing the sludge and impurities attached to the inner wall of the tank body 1 and improving the convenience of the device for cleaning the tank body 1.

[0045] In order to increase the speed of the disinfectant spraying out of the circular hole 13, so that the disinfectant can react with the sewage faster and enhance the disinfection effect of the device on the sewage, in another embodiment of the present utility model, as Figures 2 to 5As shown, the middle part of the rotating shaft 15 is fixedly connected to the second connecting rod 5; the end of the second connecting rod 5 is rotatably connected to the rotating wheel 52; the top of the water spray plate 12 is fixedly connected to a plurality of spring telescopic rods 53; the top of the spring telescopic rod 53 is fixedly connected to the top plate 54; the bottom of the top plate 54 is fixedly connected to a plurality of sliding rods 55; the sliding rods 55 and the circular holes 13 are slidingly matched; the rotating wheel 52 and the top plate 54 are correspondingly arranged; when the rotating shaft 15 rotates, it will rotate with the second connecting rod 5 and the rotating wheel 52, and when the rotating wheel 52 moves, it will generate The top plate 54 will transfer the pressure to the spring telescopic rod 53 so that the spring telescopic rod 53 is in a compressed state, and the sliding rod 55 will move closer to the water spray plate 12 along with the top plate 54 until it enters the inside of the circular hole 13. The sliding rod 55 will remove the sludge and impurities attached to the inner wall of the circular hole 13. At the same time, when the sliding rod 55 closes this part of the circular hole 13, the water flow at the remaining circular holes 13 will increase, thereby increasing the speed at which the disinfectant is sprayed out of the circular hole 13, so that the disinfectant can react with the sewage faster, thereby enhancing the disinfection effect of the device on the sewage.

[0046] In order to accelerate the separation of the sludge impurities remaining on the inner wall of the circular hole 13 and improve the cleaning effect of the device on the inner wall of the circular hole 13, in another embodiment of the present utility model, as shown in FIG. Figure 3 As shown, a fixing rod 6 is fixedly connected to the middle of the rotating wheel 52; the fixing rod 6 is an arc-shaped structure; a ball 62 is fixedly connected to the end of the fixing rod 6; when the rotating wheel 52 and the top plate 54 are in contact, they will rotate under the action of friction, and the fixing rod 6 and the ball 62 will swing as the rotating wheel 52 rotates. When the ball 62 swings, it will come into contact with the water spray plate 12 and knock on the water spray plate 12, so that the sludge impurities remaining on the inner wall of the circular hole 13 can be accelerated to separate, thereby improving the effect of the device on cleaning the inner wall of the circular hole 13.

[0047] In order to ensure that the slide rod 55 can stably enter the circular hole 13 and clean it, and improve the accuracy of the connection between the slide rod 55 and the circular hole 13, in another embodiment of the present invention, as shown in FIG. Figure 4 As shown, a plurality of guide plates 7 are fixedly connected to the top of the water spray plate 12; the guide plates 7 and the circular holes 13 are correspondingly arranged; the guide plates 7 are of a trumpet-shaped structure; when the disinfectant is sprayed out from the circular hole 13, it will pass through the guide plates 7. Because the guide plates 7 are of a trumpet-shaped structure, the guide plates 7 will cause the disinfectant to diffuse along its surface to a wider angle, thereby increasing the distribution range of the disinfectant in the tank body 1. At the same time, the guide plates 7 will also guide the slide rod 55 before it enters the circular hole 13, ensuring that the slide rod 55 can stably enter the interior of the circular hole 13 and clean it, thereby improving the accuracy of the docking between the slide rod 55 and the circular hole 13.

[0048] In order to reduce the damage to the surface of the water spray plate 12 due to impact, in another embodiment of the present invention, as Figure 4As shown, a buffer pad 8 is fixed to the middle part of the water spray plate 12; the buffer pad 8 and the ball 62 are correspondingly arranged; when the ball 62 hits the water spray plate 12, the ball 62 will come into contact with the buffer pad 8. Since the buffer pad 8 is an elastic structure, the buffer pad 8 will absorb the impact generated by the ball 62 when it comes into contact, and then transfer the attenuated impact energy to the water spray plate 12, thereby reducing the damage to the surface of the water spray plate 12 caused by the impact.

[0049] In order to make the ball 32 and the fixed block 2 more stable when they are in contact and slide along the surface of the fixed block 2, in another embodiment of the present invention, as shown in FIG. Figure 2 As shown, the surface of the fixed block 2 is an arc-shaped structure; the fixed block 2 is arranged in a circular array; because the surface of the fixed block 2 is an arc-shaped structure, the balls 32 can slide more stably along the surface of the fixed block 2 when in contact with the fixed block 2, further reducing the friction generated when the fixed block 2 and the connecting block 3 are in contact.

[0050] In order to make it possible to more stably remove impurities attached to the inner wall of the tank body 1 when the scraper 4 contacts the inner wall of the tank body 1, in another embodiment of the present invention, as Figure 3 As shown, the end of the scraper 4 is sharp; the scraper 4 is located between the tank body 1 and the stirring rod 16; because the surface of the scraper 4 is sharp, the scraper 4 can more stably remove impurities attached to the inner wall of the tank body 1 when in contact with the inner wall of the tank body 1.

[0051] Working principle: Sewage is injected into the interior of the tank body 1, and the motor 14 can be started at the same time. The water inlet pipe 110 is connected to the water pump. The water pump will input the disinfectant into the water spray plate 12 through the water inlet pipe 110, and then the disinfectant will be sprayed out from the circular hole 13. The sewage will pass through the filter pad 17 when it flows and the internal sludge impurities will be filtered out by the filter pad 17. Then the filtered sewage will reach the bottom of the tank body 1 and mix with the disinfectant. After the motor 14 is started, the shaft 15 will rotate. When the shaft 15 rotates, the stirring rod 16 will rotate and mix the disinfectant and sewage in the tank body 1, thereby accelerating the reaction rate. At the same time, the first connecting rod 18 and the cleaning rod 19 will also rotate with the shaft 15 to dredge the inside of the filter pad 17 and clean it. The rod 19 will remove the impurities blocked inside the filter pad 17, and the sewage will be disinfected after a period of time; when the first connecting rod 18 rotates, it will come into contact with the fixed block 2, and the first connecting rod 18 will slide along the surface of the fixed block 2 and shake under the extrusion. At this time, the angle of the first connecting rod 18 will change, and the cleaning rod 19 will move with the first connecting rod 18 and dredge different depths inside the filter pad 17; when the first connecting rod 18 comes into contact with the fixed block 2, the connecting block 3 and the ball 32 will also come into contact with the fixed block 2, and the ball 32 will rotate under the action of friction, so that the sliding friction between the connecting block 3 and the fixed block 2 is converted into rolling friction, reducing the friction between the fixed block 2 and the connecting block 3; the stirring rod When 16 rotates, it will drive the scraper 4 to rotate together. When the scraper 4 rotates, it will come into contact with the inner wall of the tank body 1, and the scraper 4 will clean the inner wall of the tank body 1 to reduce the sludge and impurities attached to the inner wall of the tank body 1; when the rotating shaft 15 rotates, it will drive the second connecting rod 5 and the runner 52 to rotate together. When the runner 52 moves, it will come into contact with and squeeze the top plate 54. The top plate 54 will transmit the pressure to the spring telescopic rod 53 so that the spring telescopic rod 53 is in a compressed state. The sliding rod 55 will move with the top plate 54 to the water spray plate 12 until it enters the inside of the circular hole 13. The sliding rod 55 will remove the sludge and impurities attached to the inner wall of the circular hole 13. At the same time, when the sliding rod 55 closes this part of the circular hole 13, the water flow at the remaining circular holes 13 will increase, enhancing the circular hole 13 The speed at which the disinfectant is sprayed allows the disinfectant to react with the sewage more quickly; when the runner 52 and the top plate 54 come into contact, they will rotate under the action of friction, and the fixed rod 6 and the ball 62 will swing as the runner 52 rotates. When the ball 62 swings, it will come into contact with the water spray plate 12 and knock on the water spray plate 12, so that the sludge impurities remaining on the inner wall of the circular hole 13 can be accelerated to separate; when the disinfectant is sprayed from the circular hole 13, it will pass through the guide plate 7. Because the guide plate 7 is a trumpet-shaped structure, the guide plate 7 will cause the disinfectant to diffuse along its surface to a wider angle, thereby increasing the distribution range of the disinfectant in the tank body 1. At the same time, the guide plate 7 will also guide the slide rod 55 before entering the circular hole 13, ensuring that the slide rod 55 can stably enter the interior of the circular hole 13 and clean it;When ball 62 strikes water spray plate 12, it comes into contact with cushioning pad 8. Because cushioning pad 8 is elastic, it absorbs the impact of ball 62 upon contact and then transfers the attenuated impact energy to water spray plate 12. The curved surface of fixing block 2 allows ball 32 to slide more stably along the surface of fixing block 2 when in contact. The pointed surface of scraper 4 allows scraper 4 to more stably remove impurities adhering to the inner wall of tank body 1 when in contact with the inner wall of tank body 1.
