A construction waste solid waste treatment device equipped with a dust-proof structure

Abstract

This utility model relates to the field of construction waste technology and discloses a construction waste solid waste treatment device with a dust-proof structure. The device includes a treatment box, a box cover fixedly connected to the top of the treatment box, and a water storage tank fixedly connected to the top of the box cover. The bottom of the water storage tank has a first slot and a second slot, with rotating bolts threaded onto the inner wall of the second slot. By filling the water storage tank with water and sliding a valve to expose the first slot, water falls downwards and simultaneously passes through the third and fourth slots. The water flows into the interior of the large and small drainage blades, and is sprayed out through holes on the surfaces of the first and second screens. The remaining water falls directly into the water-filtering cylinder and is sprayed outwards through a screen plate. Due to the different diameters of the large and small drainage blades and the water-filtering cylinder, the water spray coverage area varies, thus achieving a wider water distribution area to prevent dust and dissipate heat from the crushing device.

Description

Technical Field

[0001] This utility model relates to the field of construction waste technology, specifically to a construction waste solid waste treatment device equipped with a dust-proof structure. Background Technology

[0002] Construction waste refers to slag, waste soil, waste materials, silt, and other waste generated during the construction, laying, demolition, and repair of various buildings, structures, pipelines, etc. by construction units or individuals. Construction waste is generally crushed. During the processing, a large amount of dust will be generated and fill the equipment, and will escape from the equipment, affecting the surrounding environment. During the crushing process, the friction and extrusion of the crushing rollers will generate a lot of heat, causing the surface temperature of the equipment to rise. After long-term use, the high temperature will cause the material of the crushing rollers to soften or deform, thereby reducing its strength and durability. At the same time, the high temperature may cause the surface of the crushing equipment to overheat, and contact may cause safety risks such as burns.

[0003] When the above-mentioned equipment is in use, it uses gears to crush the material. If the material does not meet the requirements, it will cause blockage in the crushing chamber, increase the load on the crusher, and even damage the transmission system. After a long period of use, the surface temperature of the crushing roller will rise, leading to equipment damage or failure. The requirements for crushing gears are strict, but construction waste is diverse and may not meet the requirements, resulting in blockage in the crushing chamber and uneven crushing.

[0023] Please see Figures 1-5A construction waste solid waste treatment device with a dust-proof structure includes a treatment box 1. A box cover 2 is fixedly connected to the top of the treatment box 1. A water storage tank 3 is fixedly connected to the top of the box cover 2. A first slot 4 and a second slot 5 are opened at the bottom of the water storage tank 3. A rotating bolt 6 is threadedly connected to the inner wall of the second slot 5. A valve 7 is fixedly connected to the top of the rotating bolt 6. A drainage cylinder 8 is fixedly connected to the bottom outer wall of the first slot 4. A third slot 9 and a fourth slot 12 are respectively opened in the middle of the drainage cylinder 8. A large drainage leaf 10 is fixedly connected to the outer wall of the third slot 9. A first screen 11 is fixedly connected to the bottom of the large drainage leaf 10. A small drainage leaf 13 is fixedly connected to the outer wall of the fourth slot 12. A second screen 14 is fixedly connected to the bottom of the small drainage leaf 13. A water leakage cylinder 15 is fixedly connected to the bottom of the water leakage cylinder 15. A water sieve plate 16 is fixedly connected to the bottom of the water leakage cylinder 15. A motor 17 is installed on the outer wall of the treatment box 1. A large rotating shaft 18 is rotatably connected to the inner wall of the middle part of the processing box 1. A large crushing gear 19 and a crushing roller 20 are fixedly connected to the outer wall of the large rotating shaft 18. A large auxiliary gear 21 is fixedly connected to the middle of the inner wall of the processing box 1. An inclined screen plate 22 is fixedly connected to the inner wall of the processing box 1. A limit block 23 is fixedly connected to the bottom of the inclined screen plate 22. A small auxiliary gear 24 is fixedly connected to the inner wall of the processing box 1 on the side away from the motor 17. A small rotating shaft 25 is fixedly connected to the inner wall of the processing box 1 near the small auxiliary gear 24. A small crushing gear 26 is fixedly connected to the outer wall of the small rotating shaft 25. A motor 27 is installed on the outer wall of the processing box 1 near the top of the small rotating shaft 25. A discharge port 28 is opened on both outer walls of the processing box 1 on the sides away from the box cover 2. A five-slot 29 and a six-slot 30 are opened on the outer wall of the processing box 1 on the side away from the motor 17. A feeding assembly 31 is installed on the outer wall of the processing box 1 on the side away from the motor 17.

[0024] The inner wall of slot 4 is connected to the inner wall of water storage tank 3. The depth of slot 5 matches the length of rotating bolt 6. There are two sets of large drainage blades 10. The ends of the two sets of large drainage blades 10 away from the first screen 11 are flush with the third slot 9. The first screen 11 is located in the middle of the bottom of the two sets of large drainage blades 10. There are two sets of small drainage blades 13. The ends of the two sets of small drainage blades 13 away from the second screen 14 are flush with the fourth slot 12. The second screen 14 is located in the middle of the bottom of the two sets. The diameter of the two sets of small drainage blades 13 is smaller than the diameter of the large drainage blades 10. The diameter of the water leakage cylinder 15 is smaller than the diameter of the small drainage blades 13.

[0025] It should be noted that by rotating the bolt 6 which is threadedly connected to the two-slot 5, the valve 7 can be rotated to close the one-slot 4. When the water in the water storage bin 3 flows downward through the three-slot 9 and the four-slot 12, it flows into the large drainage blade 10 and the small drainage blade 13. Through the holes on the surfaces of the first sieve 11 and the second sieve 14, the water is evenly sprayed. Due to the different diameters of the large drainage blade 10, the small drainage blade 13, and the water leakage cylinder 15, the coverage area of the water spray is different, thus achieving a wider area of water dispersion for dust prevention and heat dissipation.

[0026] Among them, there are two large rotating shafts 18, and two groups of motors 17 are provided. The output shafts of the two groups of motors 17 penetrate through the processing box 1 and are fixedly connected to the inner wall of the large rotating shaft 18. A number of large crushing gears 19 and rolling drums 20 are provided on the outer wall of the large rotating shaft 18, and the large crushing gears 19 and the rolling drums 20 are arranged alternately. There are two groups of large auxiliary gears 21, and the two groups of large auxiliary gears 21 are flush with the large rotating shaft 18 on the inner wall of the processing box 1, and a number of the two groups of large auxiliary gears 21 are located between the large crushing gears 19 and the rolling drums 20.

[0027] It should be noted that a number of large crushing gears 19 and rolling drums 20 on the outer wall of the first group of large rotating shafts 18 are located between a number of large crushing gears 19 and rolling drums 20 on the outer wall of the second group of large rotating shafts 18, and the two groups of large rotating shafts 18 rotate in opposite directions. Through a number of large crushing gears 19 and a number of rolling drums 20, while achieving gear crushing, it can also perform rolling, crushing the construction waste evenly. With the large auxiliary gears 21 on both sides of the large rotating shaft 18, the construction waste to be processed will not leak from both sides.

[0028] Among them, the two large rotating shafts 18 are located between the five-slot 29 and the six-slot 30, and the distance between the five-slot 29 and the six-slot 30 is greater than the diameter of the large crushing gear 19.

[0029] It should be noted that the construction waste to be processed enters the processing box 1 from the five-slot 29 and the six-slot 30. Due to the distance between the five-slot 29 and the six-slot 30, the construction waste to be processed will not interfere with the operating large crushing gears 19 and rolling drums 20, and at the same time, the construction waste will not block in the feed bin 3101.

[0030] Among them, the limiting block 23 is fixedly connected to the bottom inner wall of the processing box 1. The limiting block 23 is in the shape of a "person". The bottom of the discharge port 28 is flush with the bottom end of the discharge port 28. The first inclined sieve plate 22 is located at the top of the limiting block 23 and has a non-interfering distance from the large rotating shaft 18. The first inclined sieve plate 22 is in an inclined state.

[0031] It should be noted that after the construction waste is initially crushed, it falls onto the inclined screen plate 22. After being screened by the inclined screen plate 22, the waste smaller than the hole diameter on the inclined screen plate 22 falls directly to the limiting block 23, while the waste larger than the hole diameter on the inclined screen plate 22 falls to the small crushing gear 26 through an inclined setting for further crushing before falling to the limiting block 23. Due to the shape of the limiting block 23, the crushed construction waste falls and is naturally discharged to the discharge port 28 by gravity, thus ensuring that the crushed construction waste does not block the two sides of the limiting block 23.

[0032] Among them, the small auxiliary gear 24 is located in the middle of the six slots 30 and the discharge port 28. There are two sets of small auxiliary gears 24. One set is located on the inner wall of the processing box 1 near the six slots 30, and the other set is located on the outer wall of the limiting block 23 away from the inclined screen plate 22. There are four small rotating shafts 25. Several sets of small crushing gears 26 are fixedly connected to the outer edge of the small rotating shafts 25. The two sets of small rotating shafts 25 in the middle are lower than the small rotating shafts 25 on both sides. The number of motors 27 is the same as the number of small rotating shafts 25. The output shaft of motor 27 passes through the processing box 1 and is fixedly connected to the inner wall of the small rotating shafts 25. The large rotating shaft 18 is parallel to the X-axis, and the small rotating shaft 25 is parallel to the Y-axis.

[0033] It should be noted that the two sets of small rotating shafts 25 on the side closer to the six slots 30 rotate in opposite directions to the two sets of small rotating shafts 25 on the side farther from the six slots 30. The construction waste falling from the inclined screen plate 22 is crushed evenly again by the small crushing gear 26. The large rotating shaft 18 is parallel to the X-axis and the small rotating shaft 25 is parallel to the Y-axis, which saves space and materials and makes the large rotating shaft 18 and the small rotating shaft 25 independent during operation.

[0034] The feeding assembly 31 includes a feeding bin 3101, with a feeding port 3102 at the top. An inclined screen plate 3103 is provided on the inner wall of the middle part of the feeding bin 3101. A baffle 3104 is fixedly connected to the bottom of the feeding bin 3101. The baffle 3104 is inclined. The lowest point of the inclined screen plate 3103 is flush with the bottom of the five slots 29. The top of the feeding bin 3101 is flush with the top of the five slots 29. The bottom shape of the feeding bin 3101 is the same as that of the inclined screen plate 3103. The bottom of the feeding bin 3101 is flush with the bottom of the six slots 30.

[0035] It should be noted that when construction waste enters through the feed inlet 3102 and passes through the inclined screen plate 3103, it falls downwards for initial screening. Large construction waste falls onto the large rotating shaft 18 for crushing due to the inclined state of the inclined screen plate 3103. Small construction waste falls onto the bottom inner wall of the feed hopper 3101 after being screened by the inclined screen plate 3103. Due to the inclined state of the feed hopper 3101 and the bottom of the baffle 3104, the small construction waste slides onto the inclined screen plate 22 for further screening. Waste smaller than the aperture on the inclined screen plate 22 falls directly to the limiting block 23. Waste larger than the aperture on the inclined screen plate 22 falls onto the small crushing gear 26 for further crushing before falling onto the limiting block 23.

[0036] Working principle: The worker fills the water storage tank 3 with water, slides the valve 7 to expose the first slot 4, and the water falls downwards. The water simultaneously passes through the third slot 9 and the fourth slot 12. The water flowing into the third slot 9 and the fourth slot 12 flows into the interior of the large drainage blade 10 and the small drainage blade 13, and sprays out through the holes on the surface of the first screen 11 and the second screen 14. The remaining water falls directly into the water leakage cylinder 15 and sprays outwards through the water screening plate 16. The worker starts the first motor 17 and the second motor 27. The first motor 17 and the second motor 27 drive the large rotating shaft 18 and the small rotating shaft 25 to rotate. The rotation of the large rotating shaft 18 drives the large crushing gear 19 and the crushing roller 20 to rotate, and the rotation of the small rotating shaft 25 drives the small crushing gear 26 to rotate. The worker feeds the construction waste to be processed into the feed inlet 3102. The construction waste falls downwards onto the inclined screen plate 2 3103. The construction waste that does not pass through the inclined screen plate 2 3103 passes through the feed inlet 3102. The construction waste, after being crushed and rolled by the inclined device of the inclined screen plate 2 3103, slides towards the large rotating shaft 18 and falls onto the inclined screen plate 1 22. The construction waste after the initial crushing and rolling falls downwards. The construction waste falling near the end of the baffle 3104 falls onto the surface of the baffle 3104. The inclined setting of the baffle 3104 causes the construction waste to slide onto the inclined screen plate 1 22 for screening. The construction waste falling near the end of the inclined screen plate 1 22 falls onto the surface of the inclined screen plate 1 22 for screening. The waste smaller than the aperture on the inclined screen plate 1 22 falls directly to the limiting block 23. The waste larger than the aperture on the inclined screen plate 1 22 falls through the inclined setting to the small crushing gear 26 for further crushing and then falls onto the limiting block 23 and is discharged into the discharge port 28. The construction waste screened by the inclined screen plate 2 3103 falls directly onto the bottom inner wall of the feed bin 3101. The construction waste slides towards the baffle 3104 and then slides onto the inclined screen plate 1 22 for screening again.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
