Description

Technical Field

[0001] The invention belongs to the technical field of drainage channel debris removal equipment, and in particular relates to drainage channel debris removal equipment with automatic debris removal and a debris removal method thereof. Background Art

[0002] The impurity removal equipment of drainage channels is used to remove solid impurities, sediments and other pollutants in channel water to maintain the effectiveness of the drainage system and reduce the impact on the environment. In cities and industrial areas, drainage channels help to quickly remove water accumulation caused by rainfall and other water sources, thereby preventing flooding of roads, buildings and underground facilities. Drainage channels can effectively guide water flow, reduce water erosion on the surrounding environment, control the path of water flow, and protect soil and vegetation. Drainage channels divert channel water to different treatment units, which can also guide channel water to the impurity removal equipment for treatment. The impurity removal equipment includes a grit chamber, which mainly removes heavy particles through sedimentation.

[0003] However, the existing drainage channel debris removal equipment and debris removal method with automatic debris removal are not perfect and still have certain defects:

[0004] The canal water contains a large amount of aquatic plants and solid impurities. The accumulation of aquatic plants and impurities will reduce the effective sedimentation area of ​​the impurity removal equipment, thereby reducing the sand settling effect and causing the sediment to be unable to be fully separated. The accumulated impurities may block the water flow channel, causing poor water flow and affecting the drainage capacity of the entire system. Rotting aquatic plants and impurities may produce odor and affect the quality of the surrounding environment. The cleaning process of aquatic plants and impurities by the impurity removal equipment needs to be done manually, which is not convenient enough. Summary of the invention

[0013] A method for removing impurities from a drainage channel with an automatic impurity removal device comprises the following steps:

[0014] Step 1: Use pipelines to divert canal water to the interior of the sedimentation and impurity removal box. The pore size of the first filter hole surface is larger than that of the second filter hole surface. Therefore, the first filter hole can intercept larger solid matter and remove heavy particles through sedimentation.

[0015] Step 2: After starting the micro motor, it first drives the threaded rod to transmit. Under the connection of the U-shaped plate, two auxiliary blocks move at one end of the threaded rod and the smooth rod respectively, thereby driving multiple push-scraping bars to move repeatedly inside the sedimentation and impurity removal box. The push-scraping bars are located on the top of the scraping bars. During the movement of multiple push-scraping bars on the water surface, the floating debris and water plants on the water surface can be automatically scraped to the side of the sedimentation and impurity removal box;

[0016] Step 3: As the processing plate moves, the fitting block moves back and forth at one end of the auxiliary rod, driving the multiple scraping strips to move back and forth. The bottom surfaces of the multiple scraping strips scrape back and forth on the surface of the first filter hole respectively, so as to scrape off the impurities blocked in the hole.

[0017] Step 4: The impurities scraped off by the scraping strip can be collected by the net bag, and the canal water can continue to be discharged outward through the first filter plate and the second filter hole. The canal water is purified by the sedimentation and impurity removal box.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention uses a first filter plate, a threaded rod, a micro motor, a smooth rod, a U-shaped plate, a processing plate and a push-scraping bar to guide the canal water to the interior of the sedimentation and impurity removal box through a pipeline. The aperture of the first filter hole surface is larger than the aperture of the second filter hole surface. Therefore, the first filter hole can intercept larger solid matter. The canal water after pre-filtration and impurity removal continues to be guided to the bottom of the sedimentation and impurity removal box through the first filter hole, and can be filtered again through the second filter hole. More solid matter will accumulate on the surface of the first filter plate. After starting the micro motor, the threaded rod is first driven for transmission. Under the connection of the U-shaped plate, two auxiliary blocks are respectively movable at one end of the threaded rod and the smooth rod, thereby driving a plurality of push-scraping bars to move repeatedly inside the sedimentation and impurity removal box. The push-scraping bar is located on the top of the scraping bar. During the movement of the plurality of push-scraping bars on the water surface, the push-scraping bar can automatically scrape the floating debris and aquatic plants on the water surface to the side of the sedimentation and impurity removal box, which is convenient for subsequent staff to concentrate on cleaning.

[0020] 2. The present invention cooperates with the auxiliary rod, bonding block, arc plate, L-shaped plate, scraping strip, guide plate and net bag, the auxiliary rod is embedded in the sedimentation and impurity removal box, and the bottom end of the processing plate is fixedly connected to the top end of the arc plate. Therefore, when the processing plate moves, the arc plate will move along, and the arc plate will transmit force to the bonding block, and the bonding block can move back and forth at one end of the auxiliary rod. Under the connection of the L-shaped plate, the straight plate will also move synchronously. The bottom surfaces of the multiple scraping strips themselves are in contact with the surface of the first filter plate. Therefore, under the back and forth movement of the multiple scraping strips, the two will repeatedly rub, so that the solid matter accumulated on the surface of the first filter plate can be scraped off to one side of the first filter plate, and the impurities blocked in the first filter hole can be guided downward, and the inside of the first filter hole can be combed, so that the first filter hole can filter the canal water normally later.

[0021] 3. The present invention cooperates with the splitting frame, the second filter plate, the splitting block, the positioning strips and the positioning holes, so that the impurities scraped off by the multiple scraping strips can be collected by the net bag, and the canal water can continue to be discharged outward through the first filter plate and the second filter hole. The canal water is purified by the sedimentation and impurity removal box. The multiple positioning strips are rotated in the opposite direction to separate the positioning strips from the positioning holes, so that the guide plate and the placement rack can be split, which is convenient for cleaning the net bag. The four twisting strips are rotated in the opposite direction to separate the four twisting strips from the sedimentation and impurity removal box, which is convenient for splitting the splitting frame from one side of the sedimentation and impurity removal box, and convenient for replacing the damaged splitting frame separately.

[0038] A method for removing impurities from a drainage channel with an automatic impurity removal device comprises the following steps:

[0039] Step 1: Use a pipeline to divert canal water to the interior of the sedimentation and impurity removal box 1. The pore size of the first filter hole 6 is larger than the pore size of the second filter hole 29. Therefore, the first filter hole 6 can intercept larger solid matter and remove heavy particles by sedimentation.

[0040] Step 2: After starting the micro motor 8, it first drives the threaded rod 7 to transmit. Under the connection of the U-shaped plate 11, the two auxiliary blocks 10 move at one end of the threaded rod 7 and the smooth rod 9 respectively, thereby driving the multiple push-scraping bars 14 to move repeatedly inside the sedimentation and impurity removal box 1. The push-scraping bars 14 are located on the top of the scraping bars 21. During the movement of the multiple push-scraping bars 14 on the water surface, the floating debris and water plants on the water surface can be automatically scraped to the side of the sedimentation and impurity removal box 1;

[0041] Step 3: As the processing plate 13 moves, the fitting block 17 moves back and forth at one end of the auxiliary rod 16, driving the multiple scraping strips 21 to move back and forth. The bottom surfaces of the multiple scraping strips 21 scrape back and forth on the surface of the first filter hole 6, respectively, to scrape off the impurities blocked in the hole.

[0042] Step 4: the impurities scraped off by the scraping strip 21 can be collected by the net bag 24, and the canal water can continue to be discharged outward through the first filter plate 5 and the second filter hole 29, and the canal water is purified by the sedimentation and impurity removal box 1.

[0043] The working principle and use process of the present invention: The impurity removal equipment of the drainage channel is used to remove solid impurities, sediments and other pollutants in the channel water to maintain the effectiveness of the drainage system and reduce the impact on the environment. In cities and industrial areas, the drainage channel helps to quickly remove the accumulated water caused by rainfall and other water sources, thereby preventing flooding of roads, buildings and underground facilities. The drainage channel can effectively guide the water flow, reduce the erosion of the water flow on the surrounding environment, control the path of the water flow, and protect the soil and vegetation. The drainage channel diverts the channel water to different treatment units, and can also guide the channel water to the impurity removal equipment for treatment. The impurity removal equipment includes a sand settling tank. The grit chamber mainly removes heavy particles by sedimentation, and diverts the canal water to the interior of the sedimentation and impurity removal box 1 through a pipe. The aperture of the first filter hole 6 is larger than the aperture of the second filter hole 29. Therefore, the first filter hole 6 can intercept larger solid matter, and the second filter hole 29 can intercept smaller solid matter. The combination of the two can filter the solid impurities in the canal water more finely. The canal water after pre-filtration and impurity removal continues to be diverted to the bottom of the sedimentation and impurity removal box 1 through the first filter hole 6, and can be filtered again through the second filter hole 29. More solid matter will accumulate on the surface of the first filter plate 5. The protective cover 15 can enhance the resistance of the threaded rod 7 to external forces. The protective cover 15 is located on the top of one of the convex plates 2 and can cover the outer surface of the threaded rod 7. After starting the micro motor 8, the threaded rod 7 is first driven to transmit. One of the auxiliary blocks 10 is threadedly sleeved with one end of the threaded rod 7, and the other auxiliary block 10 is movably sleeved with one end of the smooth rod 9. Therefore, under the rotation of the threaded rod 7, the two auxiliary blocks 10 move at the same time. Under the connection of the U-shaped plate 11, the two auxiliary blocks 10 are respectively movable at one end of the threaded rod 7 and the smooth rod 9. The U-shaped plate 11 and the processing plate 13 are connected by two The reinforcement rod 12 is connected, so that the plurality of push-scraping strips 14 can be driven to move repeatedly inside the sedimentation and impurity removal box 1. The push-scraping strips 14 are located on the top of the scraping strips 21. During the movement of the plurality of push-scraping strips 14 on the water surface, the push-scraping strips 14 can automatically scrape the floating debris and aquatic plants on the water surface to the side of the sedimentation and impurity removal box 1, which is convenient for subsequent staff to concentrate on cleaning. The auxiliary rod 16 is embedded in the sedimentation and impurity removal box 1, and the bottom end of the processing plate 13 is fixedly connected to the top end of the arc plate 18. Therefore, when the processing plate 13 moves, the arc plate 18 will move with it, and the arc plate 18 will transmit the force to the fitting block 17.The fitting block 17 can move back and forth at one end of the auxiliary rod 16. Under the connection of the L-shaped plate 19, the straight plate 20 will also move synchronously. The bottom surfaces of the plurality of scraping strips 21 are in contact with the surface of the first filter plate 5. Therefore, under the back and forth movement of the plurality of scraping strips 21, the two will rub repeatedly, so that the solid matter accumulated on the surface of the first filter plate 5 can be scraped off to one side of the first filter plate 5, and the impurities blocked in the first filter hole 6 can be guided downward, and the inside of the first filter hole 6 can be combed, so that the first filter hole 6 can filter the canal water normally later. The impurities scraped off by the plurality of scraping strips 21 can be collected by the net bag 24. The canal water can continue to be discharged outward through the first filter plate 5 and the second filter hole 29, and the canal water is purified by the sedimentation and impurity removal box 1. The multiple positioning bars 25 are rotated in the opposite direction to separate the positioning bars 25 from the positioning holes 26, so that the guide plate 22 and the placement frame 23 can be separated, which is convenient for cleaning the net bag 24. The four twisting bars 31 are rotated in the opposite direction to separate the four twisting bars 31 from the sedimentation and impurity removal box 1, which is convenient for disassembling the split frame 27 from one side of the sedimentation and impurity removal box 1, and it is convenient to replace the damaged split frame 27 separately. The structures inside the sedimentation and impurity removal box 1 are all made of stainless steel, and the surface is sprayed with anti-corrosion agent to extend the service life.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
