Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater treatment bar with self-cleaning function. Background Technology

[0002] Wastewater refers to polluted wastewater generated in production and daily life. It includes wastewater containing heavy metals, organic matter and other pollutants discharged from industrial production, wastewater containing suspended solids, detergents and bacteria generated from washing clothes, cooking and using the toilet, as well as runoff carrying pesticides and fertilizers after agricultural irrigation. Its water quality varies significantly depending on the source. If solid impurities and other pollutants are discharged directly without treatment, they will pollute the water body, soil and other ecological environment, and endanger the health of animals, plants and humans. It must be purified through processes such as screen interception, biological treatment, sedimentation and filtration before it can meet the standards for discharge or reuse.

[0003] Bar screens are key equipment in sewage treatment and pumping station systems. They are mainly used to intercept floating objects and solid impurities in sewage and rainwater, such as plastic bags, branches, and fibers, to prevent them from clogging pumps, pipes, and other subsequent treatment equipment. They are widely used in municipal drainage, industrial wastewater treatment, and other fields, effectively improving system operating efficiency and stability.

[0004] Existing bar screens accumulate a lot of pollutants on their surface when used for a long time, which reduces their blocking effect and causes blockage. Therefore, a wastewater treatment bar screen with self-cleaning function is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A sewage treatment bar with self-cleaning function, comprising a blocking box; a motor fixedly connected to the side wall of the blocking box; a bar body fixedly connected to the output end of the motor; the bar body rotatably connected to the inner side wall of the blocking box; a collection box slidably connected to the side wall of the blocking box; a groove opened at the bottom of the collection box; a sliding rod fixedly connected to the side wall of the blocking box; a slider slidably connected to the middle of the sliding rod; a first support rod fixedly connected to the bottom end of the slider; and a collection box fixedly connected to the bottom end of the first support rod. When floating objects accumulate on the surface of the bar body, the motor drives the bar body to rotate at a specified angle, causing pollutants to fall into the collection box due to gravity, thereby achieving automatic cleaning, reducing the frequency of manual cleaning, reducing the decrease in water flow caused by bar blockage, and preventing sewage overflow.

[0007] Preferably, a pair of first fixing seats are fixedly connected to the side wall of the blocking box; the first fixing seats are symmetrically arranged on the side wall of the blocking box; a first electric push rod is fixedly connected to the bottom end of the first fixing seat; a push plate is fixedly connected to the bottom end of the first electric push rod; the push plate is slidably connected to the side wall of the first electric push rod; after the push plate contacts the bottom of the collection box, it moves in coordination with the collection box to push the pollutants into the trough. A waste box can be placed at the bottom of the trough so that floating objects are collected in a concentrated manner for subsequent treatment, and the accumulation of floating objects in the collection box for a long time can be reduced, thus reducing the risk of the collection box becoming too full.

[0008] Preferably, a second support rod is fixedly connected to the side wall of the barrier box; a second electric push rod is fixedly connected to the top of the second support rod; a scraper is slidably connected to the side wall of the barrier box; the second electric push rod is connected to the scraper; when the scraper is in contact with the side wall of the grid body, it can scrape off floating objects or sticky substances entangled in the grid body, reducing the reduction of the effective interception area of ​​the grid body due to pollutant adhesion.

[0009] Preferably, a pair of second fixing seats are fixedly connected to the inner side wall of the barrier box; the second fixing seats are respectively located above and below the bar screen body; a damping spring telescopic rod is fixedly connected to the bottom end of the second fixing seat; a blocking block is fixedly connected to the bottom end of the damping spring telescopic rod; by blocking the bar screen body with the blocking block, the damping spring telescopic rod releases its elastic force to push the bar screen body back, which can ensure that the bar screen body always stays at the optimal interception angle, reduce the failure of sewage interception caused by the angle deviation of the bar screen body, and control the angle deviation within a specified range.

[0010] Preferably, a third fixing seat is fixedly connected to the side wall of the scraper; a striking rod is fixedly connected to the side wall of the third fixing seat; a flexible pad is fixedly connected to the side wall of the striking rod; the vibration generated by the flexible pad striking the side wall of the grid body can reduce the adhesion between pollutants and the surface of the grid body, causing them to detach from the grid body and increasing cleaning efficiency.

[0011] Preferably, a telescopic plate is fixedly connected to the bottom end of the second fixed base; a pair of fixed rods are fixedly connected to the top end of the telescopic plate; the fixed rods are connected to the side wall of the blocking block; by blocking sewage from contacting the damping spring telescopic rod through the telescopic plate, the corrosion of the damping spring telescopic rod by sewage after long-term use can be reduced, which would cause the damping spring telescopic rod to be unsmooth when extending and retracting, thereby increasing the service life of the damping spring telescopic rod and reducing its maintenance.

[0012] The advantages of this utility model are: 1. The wastewater treatment bar with self-cleaning function described in this utility model automatically cleans the bar body by rotating it at a specified angle when floating objects accumulate on its surface.

[0013] 2. The wastewater treatment grid with self-cleaning function described in this utility model, after the push plate contacts the bottom of the collection box, moves in coordination with the collection box to push pollutants into the trough. A waste box can be placed at the bottom of the trough to collect floating objects for subsequent treatment, and can also reduce the accumulation of floating objects in the collection box for a long time, which may lead to overfilling.

After the surface of the screen body 12 has blocked a large number of floating objects, the slider 16 can be pushed to slide in the middle of the sliding rod 15. The collection box 13 slides into the blocking box 1, and then the motor 11 is started to drive the grille body 12 to rotate, causing the upward-facing side of the grille body 12 to flip downward. As the grille body 12 flips, the pollutants blocked on the surface of the grille body 12 will fall into the collection box 13 due to gravity, thus cleaning the surface of the grille body 12. Then the motor 11 drives the grille body 12 to rotate back to its original position to continue blocking floating objects, pushing the slider 16 to move in the middle of the slide bar 15, removing the pollutants collected in the collection box 13 from the trough 14, thus completing the automatic cleaning. By rotating the grille body 12 at a specified angle when floating objects accumulate on its surface, the motor 11 causes the grille body 12 to fall into the collection box 13 due to gravity, thus achieving automatic cleaning, reducing the frequency of manual cleaning, reducing the reduction of water flow caused by grille blockage, and preventing sewage overflow.

[0020] like Figure 1 and Figure 5 As shown, a pair of first fixed seats 2 are fixedly connected to the side wall of the blocking box 1; the first fixed seats 2 are symmetrically arranged on the side wall of the blocking box 1; a first electric push rod 21 is fixedly connected to the bottom end of the first fixed seat 2; a push plate 22 is fixedly connected to the bottom end of the first electric push rod 21; the push plate 22 is slidably connected to the side wall of the first electric push rod 21; during operation, after the collection box 13 collects pollutants, when the slider 16 drives the collection box 13 into the blocking box 1 for the next time, the first electric push rod 21 can be pushed first to drive the push plate 22 down, so that the push plate 22... When the collection box 13 comes into contact with the bottom, as the collection box 13 moves into the blocking box 1 next time, the pollutants inside the collection box 13 will be pushed to the trough 14 by the push plate 22 and fall from the trough 14, so that the collected pollutants are automatically cleaned up. After the push plate 22 comes into contact with the bottom of the collection box 13, it moves in coordination with the collection box 13 to push the pollutants to the trough 14. A waste box can be placed at the bottom of the trough 14 so that the floating objects are collected in a concentrated manner for subsequent treatment. It can also reduce the accumulation of floating objects in the collection box 13 for a long time, which may cause it to become too full.

[0021] like Figure 1 and Figure 4 As shown, a second support rod 3 is fixedly connected to the side wall of the blocking box 1; a second electric push rod 31 is fixedly connected to the top of the second support rod 3; a scraper 32 is slidably connected to the side wall of the blocking box 1; the second electric push rod 31 is connected to the scraper 32; during operation, when the motor 11 rotates the grille body 12 to a position parallel to the scraper 32, the rotation of the grille body 12 is stopped, and then the second electric push rod 31 is pushed to drive the scraper 32 to move. The scraper 32 can contact the side wall of the grille body 12 to scrape off the pollutants stuck on the side wall of the grille body 12 and drop them into the collection box 13; when the scraper 32 is in contact with the side wall of the grille body 12, it can scrape off the floating objects or sticky substances wrapped around the grille body 12, reducing the reduction of the effective interception area of ​​the grille body 12 due to pollutant adhesion.

[0022] like Figures 2 to 3 As shown, a pair of second fixing seats 4 are fixedly connected to the inner side wall of the blocking box 1; the second fixing seats 4 are respectively located above and below the bar screen body 12; a damping spring telescopic rod 41 is fixedly connected to the bottom end of the second fixing seat 4; a blocking block 42 is fixedly connected to the bottom end of the damping spring telescopic rod 41; during operation, when the motor 11 rotates to return to its original position, the pair of second fixing seats 4 on the side wall of the blocking box 1 can contact the bar screen body 12. When the motor 11 rotates beyond its original position, the blocking block 42 blocks, and the damping spring telescopic rod 41 retracts elastically, which can push the bar screen body 12 back to its original position; by blocking the bar screen body 12 with the blocking block 42 and the damping spring telescopic rod 41 releasing elastic force to push the bar screen body 12 back, it can be ensured that the bar screen body 12 always stays at the optimal interception angle, reducing the failure of sewage interception caused by the angle deviation of the bar screen body 12, and controlling the angle deviation within a specified range.

[0023] like Figure 1 and Figure 4 As shown, a third fixing seat 5 is fixedly connected to the side wall of the scraper 32; a striking rod 51 is fixedly connected to the side wall of the third fixing seat 5; a flexible pad 52 is fixedly connected to the side wall of the striking rod 51; during operation, when the scraper 32 scrapes the side wall of the grid body 12, the striking rod 51 can be activated to drive the flexible pad 52 to strike the side wall of the grid body 12, causing the pollutants to vibrate; the vibration generated by the flexible pad 52 striking the side wall of the grid body 12 can reduce the adhesion between the pollutants and the surface of the grid body 12, causing them to detach from the grid body 12, thus increasing the cleaning efficiency.

[0024] like Figures 2 to 3As shown, a telescopic plate 6 is fixedly connected to the bottom end of the second fixed base 4; a pair of fixed rods 61 are fixedly connected to the top end of the telescopic plate 6; the fixed rods 61 are connected to the side wall of the blocking block 42; during operation, when the damping spring telescopic rod 41 retracts, the telescopic plate 6 can move with the blocking block 42 and retract and expand simultaneously, wrapping the damping spring telescopic rod 41 so that sewage will not directly contact the surface of the damping spring telescopic rod 41; by blocking sewage from contacting the damping spring telescopic rod 41 through the telescopic plate 6, the corrosion of the damping spring telescopic rod 41 by sewage after long-term use can be reduced, which would cause the damping spring telescopic rod 41 to be less smooth when extending and retracting, thus increasing the service life of the damping spring telescopic rod 41 and reducing its maintenance.

[0025] Working principle: After the blocking box 1 is installed in the designated position, the screen body 12 starts to work, intercepting floating objects in the sewage. When a large amount of floating objects are blocked on the surface of the screen body 12, the slider 16 can be pushed to slide in the middle of the slide rod 15, causing the collection box 13 to slide into the blocking box 1. Then, the motor 11 is started to drive the screen body 12 to rotate, causing the upward-facing side of the screen body 12 to flip to the bottom. As the screen body 12 rotates, the pollutants blocked on the surface of the screen body 12 will fall into the collection box 13 due to gravity, thus allowing the screen body to pass through the sewage. After the surface of the grid body 12 is cleaned, the motor 11 drives the grid body 12 back to its original position to continue blocking floating objects. This pushes the slider 16 to move in the middle of the slide bar 15, removing the contaminants collected by the collection box 13 from the drain 14, thus completing the automatic cleaning. After the collection box 13 collects contaminants, when the slider 16 drives the collection box 13 into the blocking box 1 again, the first electric push rod 21 can be pushed to lower the push plate 22, causing the push plate 22 to contact the bottom of the collection box 13. When the collection box 13 moves into the blocking box 1 again, the collection box 1... 3. The internal contaminants are pushed to the trough 14 by the push plate 22 and fall from the trough 14, causing the collected contaminants to be automatically cleaned. When the motor 11 rotates the grille body 12 to a position parallel to the scraper 32, the rotation of the grille body 12 stops, and then the second electric push rod 31 is pushed to drive the scraper 32 to move. The scraper 32 can contact the side wall of the grille body 12 and scrape off the contaminants stuck on the side wall of the grille body 12, which fall into the collection box 13. When the motor 11 rotates to return to the original position, the pair of second fixing seats 4 on the side wall of the blocking box 1 can engage with the grille body. When the motor 11 rotates beyond its original position, the blocking block 42 blocks the body 12, and the damping spring telescopic rod 41 retracts elastically, which can push the body 12 back to its original position. When the scraper 32 scrapes the side wall of the body 12, the striking rod 51 can be activated to drive the flexible pad 52 to strike the side wall of the body 12, causing the pollutants to vibrate. When the damping spring telescopic rod 41 retracts, the telescopic plate 6 can move with the blocking block 42 and simultaneously retract and expand, wrapping the damping spring telescopic rod 41 so that the sewage does not directly contact the surface of the damping spring telescopic rod 41.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
