Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a slag-removing device for an inner diameter flow grid collection hopper. Background Technology

[0002] An internal flow bar screen is a device used in wastewater treatment facilities to intercept and collect larger solid waste. As water flows through the bar screen, larger objects are blocked and accumulate in the collection hopper above or below the bar screen. To ensure the effective operation of the system, these accumulated scrapers must be removed regularly.

[0003] In practical applications of internal flow bar screens, the bar is designed as an elliptical cylinder that rotates continuously. During rotation, water flows through the bar, and impurities remain on it, forming sludge. Existing collection hoppers often rely on gravity to allow the sludge to fall into the hopper, which is inefficient. The sludge accumulates in the hopper and may undergo fermentation, generating additional pollutants. Therefore, a sludge cleaning device for the collection hopper of an internal flow bar screen is proposed. Utility Model Content

[0004] The main purpose of this invention is to provide a slag removal device for an internal flow grid collection hopper, which solves the problem that existing collection hoppers often rely on gravity to allow the slag to fall into the collection hopper by itself during slag collection, which is not efficient enough. The slag may accumulate in the collection hopper and ferment, generating additional pollutants.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A slag-removing device for an internal flow bar screen collection hopper includes an internal flow bar screen machine. A bar screen body is movably installed inside the internal flow bar screen machine. A scraper abuts against one side of the bar screen body. Connecting blocks are fixedly connected to both sides of the scraper. Connecting slots are provided on both sides of the internal flow bar screen machine. Two connecting blocks pass through the two connecting slots respectively. Limiting blocks are fixedly connected to the outer sides of the two connecting blocks. Limiting rails are movably sleeved on the outer sides of the two limiting blocks. The internal flow bar screen machine is fixedly connected to the inner sides of the two limiting rails. Springs are fixedly connected to the inner sides of the two limiting blocks. The internal flow bar screen machine is fixedly connected to the inner sides of the two springs.

[0007] Furthermore, a motor is fixedly connected to one side of the internal flow bar screen, and a first transmission rod is fixedly connected to the output end of the motor. The first transmission rod is movably mounted on the internal flow bar screen, and two transmission discs are fixedly sleeved at equal intervals on the outer side of the first transmission rod. The outer sides of the two transmission discs are toothed into the bar screen body.

[0008] Furthermore, a first ratchet is fixedly connected to one end of the first transmission rod, and the first ratchet is located on the outside of the inner diameter flow bar screen. A chain is toothed on the outside of the first ratchet, and a second ratchet is toothed on the inside of the chain. A second transmission rod is fixedly connected to the inside of the second ratchet, and a limiting sleeve is sleeved on the outside of the second transmission rod. The inner side of the limiting sleeve is fixedly connected to the inner diameter flow bar screen.

[0009] Furthermore, a rotating disk is fixedly connected to the outer side of the second ratchet, and a plurality of first pressing blocks are fixedly connected at equal intervals to the outer side of the rotating disk. A second pressing block is fixedly connected to the outer side of one of the connecting blocks, and the inner side of the second pressing block abuts against the rotating disk.

[0010] Furthermore, a first bevel gear is fixedly connected to the outer side of the first ratchet, a second bevel gear is toothed below the first bevel gear, a third transmission rod is fixedly connected below the second bevel gear, a limit base is movably sleeved on the outer side of the third transmission rod, an inner diameter flow bar machine is fixedly connected to the inner side of the limit base, and a worm gear is fixedly connected below the third transmission rod.

[0011] Furthermore, a first roller is fixedly installed on one side of the internal flow bar screen, and a second roller is fixedly installed on the other side of the internal flow bar screen. A transmission belt is sleeved on the outer side of the first roller and the second roller, and the transmission belt passes through two connecting grooves. A worm gear is fixedly connected to the outer side of the first roller, and a worm is toothed on one side of the worm gear.

[0012] Furthermore, a collection hopper is fixedly connected inside the internal flow bar screen, and the collection hopper is located inside the bar screen body. A protective cover is fixedly connected to the outside of the internal flow bar screen, and a control panel is fixedly connected to one side of the internal flow bar screen.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model, through the design of the scraper, can actively clean the inner surface of the grid body, improving the collection efficiency of slag. When the rotating disk rotates, it can drive several first extrusion blocks to rotate. The first extrusion blocks sequentially extrude and push the second extrusion block. When the first extrusion block extrudes the second extrusion block, the second extrusion block drives a connecting block to move. This connecting block drives a spring to stretch through a limiting block. At the same time, this connecting block drives the scraper to move. The scraper drives another spring to compress through another connecting block and a limiting block. When the first extrusion block no longer extrudes the second extrusion block, the spring resets and drives the scraper to reset. The scraper scrapes off the slag on the surface of the grid body in reciprocating motion. Through this design, the inner surface of the grid body can be actively cleaned, improving the collection efficiency of slag.

[0015] 2. This utility model, through the installation of a transmission belt, continuously discharges the slag collected in the collection hopper, preventing secondary pollution caused by slag fermentation and avoiding blockages. The first transmission rod drives the worm gear to rotate via the first bevel gear, the second bevel gear, and the third transmission rod. The worm gear drives the worm wheel to rotate, and the worm wheel drives the transmission belt to move via the first roller. The transmission belt continuously discharges the slag that falls on it from the inner diameter flow bar screen, thus facilitating the collection and cleaning of the slag. Through this design, the slag collected in the collection hopper can be continuously discharged, preventing secondary pollution caused by slag fermentation and avoiding blockages.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-7 As shown, a slag-removing device for an internal flow bar screen collection hopper includes an internal flow bar screen machine 1. A bar screen body 4 is movably installed inside the internal flow bar screen machine 1. A scraper 17 abuts against one side of the bar screen body 4. Connecting blocks 13 are fixedly connected to both sides of the scraper 17. Connecting grooves 29 are provided on both sides of the internal flow bar screen machine 1. Two connecting blocks 13 pass through the two connecting grooves 29 respectively. Limiting blocks 14 are fixedly connected to the outer sides of both connecting blocks 13. Limiting blocks 14 are movably sleeved on the outer sides of both limiting blocks 14. The inner sides of the two limiting rails 16 are fixedly connected to the inner diameter flow bar screen machine 1. The inner sides of the two limiting blocks 14 are fixedly connected to the springs 15. The inner sides of the two springs 15 are fixedly connected to the inner diameter flow bar screen machine 1. By adopting the above technical solution, the scraper 17 is wavy in shape. The scraper 17 can increase the contact area with the bar screen surface without increasing the overall size. At the same time, the reciprocating motion of the scraper 17 can scrape off the slag from the side, thereby more effectively removing the slag attached to the bar screen body 4.

[0028] The scraper 17 is inclined, which can guide the scraped slag onto the transmission belt 26. At the same time, the reciprocating motion of the scraper 17 can prevent the slag from depositing on the scraper 17.

[0029] The limiting track 16 can limit the limiting block 14 to move only along the direction of the limiting track 16. The limiting block 14, in turn, limits the scraper 17 to move only in a straight line through the connecting block 13, keeping it in close contact with the grid body 4. The scraper 17 is made of a wear-resistant material with a certain elasticity.

[0030] The internal limit installation mechanism of the internal flow bar screen 1 can limit the bar screen body 4 to move only along its own shape trajectory.

[0031] The scraper 17 is positioned above the transmission belt 26.

[0032] like Figures 1-3 As shown, a motor 3 is fixedly connected to one side of the inner diameter flow bar screen 1, and a first transmission rod 5 is fixedly connected to the output end of one side of the motor 3. The first transmission rod 5 is movably installed on the inner diameter flow bar screen 1. Two transmission discs are fixedly sleeved at equal intervals on the outer side of the first transmission rod 5. The outer sides of the two transmission discs are toothed into the bar screen body 4. By adopting the above technical solution, the motor 3 can drive the bar screen body 4 to move through the first transmission rod 5 and the transmission discs.

[0033] The rotation direction of the first transmission rod 5 is designed, and the movement direction of the first transmission rod 5 and the transmission disc driving the grid body 4 is designed. The grid body 4 first moves to the top of the collection hopper 30, and the slag falls into the collection hopper 30. Then the grid body 4 moves to the scraper 17 to scrape it off.

[0034] like Figures 1-7 As shown, one end of the first transmission rod 5 is fixedly connected to a first ratchet 6, and the first ratchet 6 is located on the outside of the inner diameter flow bar screen 1. The outer side of the first ratchet 6 is connected to a chain 7, and the inner side of the chain 7 is connected to a second ratchet 8. The inner side of the second ratchet 8 is fixedly connected to a second transmission rod 9. The outer side of the second transmission rod 9 is sleeved with a limiting sleeve, and the inner side of the limiting sleeve is fixedly connected to the inner diameter flow bar screen 1. With this arrangement, the limiting sleeve can limit the second transmission rod 9, preventing the second transmission rod 9 from disengaging from the limiting sleeve during movement, and allowing it to rotate only within the limiting sleeve.

[0035] like Figures 1-7 As shown, a rotating disk 10 is fixedly connected to the outer side of the second ratchet 8. Several first pressing blocks 11 are fixedly connected to the outer side of the rotating disk 10 at equal intervals. A second pressing block 12 is fixedly connected to the outer side of a connecting block 13, and the inner side of the second pressing block 12 abuts against the rotating disk 10. With this arrangement, the position of the second pressing block 12 corresponds to the first pressing block 11, so that when the first pressing block 11 rotates around the rotating disk 10 as the axis, it can continuously press the second pressing block 12.

[0036] The second extrusion block 12 is symmetrically arranged along the circumference on the rotating disk 10.

[0037] like Figures 1-8 As shown, a first bevel gear 18 is fixedly connected to the outer side of the first ratchet 6, a second bevel gear 19 is meshed below the first bevel gear 18, a third transmission rod 20 is fixedly connected below the second bevel gear 19, a limiting base 21 is movably sleeved on the outer side of the third transmission rod 20, an inner diameter flow bar screen 1 is fixedly connected to the inner side of the limiting base 21, and a worm gear 22 is fixedly connected below the third transmission rod 20. With this arrangement, the limiting base 21 can limit the third transmission rod 20, preventing it from moving up and down and allowing it to rotate only around its own axis.

[0038] like Figures 1-8 As shown, a first roller 24 is fixedly installed on one side of the internal flow bar screen 1, and a second roller 25 is fixedly installed on the other side of the internal flow bar screen 1. A transmission belt 26 is sleeved on the outer side of the first roller 24 and the second roller 25, and the transmission belt 26 passes through two connecting grooves 29. A worm gear 23 is fixedly connected to the outer side of the first roller 24, and one side of the worm gear 23 is toothed into a worm 22. With this arrangement, a limiting device is installed on the outer side of the first roller 24 and the second roller 25. The limiting device can limit the position of the first roller 24 and the second roller 25 through the connected internal flow bar screen 1, without affecting the rotation of the first roller 24 and the second roller 25.

[0039] The inner diameter flow bar screen 1 is equipped with a collection device on the outside, which allows users to easily collect and clean the slag discharged from the drive belt 26 from the outside.

[0040] like Figures 1-8 As shown, the internal flow bar screen 1 is fixedly connected to a collection hopper 30, which is located inside the bar screen body 4. The external side of the internal flow bar screen 1 is fixedly connected to a protective cover 27. A control panel 2 is fixedly connected to one side of the internal flow bar screen 1. The control panel 2 is electrically connected to a motor 3. With this arrangement, the protective cover 27 has a through hole, which does not affect the movement of the second extrusion block 12. The worm gear 23 is connected to the first roller 24 through a connecting rod. The connecting rod is movably sleeved on the protective cover 27. The protective cover 27 is installed on the outside of components such as the second bevel gear 19, the third transmission rod 20, and the second ratchet 8, which can provide protection.

[0041] The lower side of the collecting hopper 30 is set on the transmission belt 26. The collecting hopper 30 is set at an angle, and the slag falling on the collecting hopper 30 can fall onto the transmission belt 26 along the collecting hopper 30.

[0042] It should be noted that during use, the motor 3 is started through the control panel 2. The motor 3 starts the movement of the bar screen body 4 through the first transmission rod 5 and the transmission disc. Water flows continuously through the bar screen body 4, and impurities in the water flow remain on the surface of the bar screen body 4. During the movement of the bar screen body 4, the slag on the bar screen body 4 falls onto the collection hopper 30, and then is guided by the collection hopper 30 onto the transmission belt 26.

[0043] Simultaneously, the first transmission rod 5 drives the rotating disk 10 to rotate via the first ratchet 6, chain 7, and second ratchet 8. When the rotating disk 10 rotates, it can drive several first extrusion blocks 11 to rotate. The several first extrusion blocks 11 sequentially extrude and push the second extrusion block 12. When the first extrusion block 11 extrudes the second extrusion block 12, the second extrusion block 12 drives a connecting block 13 to move. This connecting block 13 drives the spring 15 to stretch via the limiting block 14. At the same time, this connecting block 13 drives the scraper 17 to move. The scraper 17 drives another spring 15 to compress via another connecting block 13 and limiting block 14. When the first extrusion block 11 no longer extrudes the second extrusion block 12, the spring 15 resets and drives the scraper 17 to reset. The scraper 17 scrapes the surface of the grid body 4 in the reciprocating motion, scraping off the slag. The slag falls onto the transmission belt 26.

[0044] The first transmission rod 5 drives the worm gear 22 to rotate via the first ratchet 6, the first bevel gear 18, the second bevel gear 19 and the third transmission rod 20. The worm gear 22 drives the worm wheel 23 to rotate. The worm wheel 23 drives the transmission belt 26 to move via the first roller 24. The transmission belt 26 continuously discharges the slag that falls on the transmission belt 26 from the inner diameter flow bar screen 1.

[0045] This utility model provides a slag removal device for an internal flow grid collection hopper, which solves the problem that existing collection hoppers 30 often rely on gravity to allow the slag to fall into the collection hopper 30 during slag collection, which is not efficient enough. The slag may accumulate in the collection hopper 30 and ferment, generating additional pollutants. This device is more practical.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
