Description

Technical Field

[0001] This utility model belongs to the field of construction equipment technology, specifically a crushing device for recycling construction solid waste. Background Technology

[0002] Solid waste is generated during the construction process, including construction debris, concrete blocks, broken bricks, and decoration waste. Some of this solid waste can be recycled after being crushed, thus improving the utilization rate of materials.

[0003] Construction waste crushing equipment typically uses the interlocking force of crushing rollers to crush large pieces of construction waste into smaller pieces or particles. For example, crushed concrete blocks can be turned into aggregates, which can be used as raw materials for road bases and concrete blocks. However, existing crushing equipment usually has a vertical channel between the crushing position and the feeding port. During crushing, fragments will fly out of the feeding port, which can cause injury to the operator when the flying fragments hit the operator.

[0004] Therefore, this utility model provides a crushing device for recycling construction solid waste. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background art, a crushing device for recycling construction solid waste is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The crushing device for recycling construction solid waste according to this utility model includes a crushing chamber, a feeding hopper at the bottom of the crushing chamber, a guide pipe installed at the top of the crushing chamber, the middle section of the guide pipe having an inclined structure, a pair of crushing rollers installed inside the crushing chamber, a motor installed on the side wall of the crushing chamber, gears installed at the ends of the crushing rollers, a dust removal component installed on the side wall of the crushing chamber, a dirt removal component installed at the bottom of the feeding hopper, and a material stabilizing component installed at the top of the guide pipe. Through the above structure, the inclined guide pipe installed at the top of the crushing chamber can make the material entry position staggered from the crushing chamber, thereby reducing the situation where fragments of construction waste fly out from the top of the crushing chamber and cause injury to the operator when they fly out during the crushing process.

[0007] Preferably, the dust removal assembly includes a fixed box, which is installed on the side wall of the crushing chamber. An air inlet pipe is connected to the side wall of the feed pipe and connected to the top of the fixed box. A fan is connected to the side wall of the fixed box, and a cover plate is installed on the side wall of the fixed box. A fixing component is provided on the side wall of the fixed box, and a fixing plate is slidably connected inside the fixed box. Multiple filter bags are installed on the fixing plate. Through the above structure, the fan and the air inlet pipe draw dust from the feed pipe into the fixed box for filtration, thereby reducing the dust generated during the crushing of construction waste from drifting to the outside, which could lead to environmental pollution and harm to the health of operators.

[0008] Preferably, the fixing assembly includes a pair of baffles, which are hinged to the side wall of the fixing box. A pair of connecting shafts are hinged to the side wall of the fixing box, and a pressure ring is threaded onto the connecting shaft. A rotating wheel is installed on the pressure ring. With the above structure, the connecting shaft, pressure ring and rotating wheel press the baffles onto the surface of the cover plate, eliminating the need for many fastening bolts. This facilitates the fixing and disassembly of the cover plate on the fixing box, thereby facilitating the installation and disassembly of the fixing plate and filter bag inside the fixing box.

[0009] Preferably, the impurity removal component includes a pair of fixing bars, which are symmetrically fixed to the bottom of the hopper. A frame is installed on the fixing bars, and a connecting component is provided on the fixing bars and the frame. Multiple sets of barbs are fixed to the frame. Through the above structure, the multiple sets of barbs hook the plastic or cloth impurities in the crushed construction waste, thereby reducing the impurities in the crushed material and facilitating the reuse of the crushed material in the later stage.

[0010] Preferably, the connecting assembly includes two pairs of fixing posts, with the two sets of fixing posts respectively fixed to the top of a pair of fixing strips. The frame is provided with two sets of positioning holes. Through the above structure, the fixing posts and positioning holes fit together, which facilitates the installation and disassembly of the frame and the barb at the bottom of the hopper, and makes it convenient to remove the barb to clean up the hooked debris.

[0011] Preferably, the material stabilizing component includes a feeding hopper, which is fixed to the top of the guide pipe. With the above structure, the feeding hopper has a structure that is larger at the top and smaller at the bottom, which can reduce the situation where materials fall to the outside when they are added.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The crushing device for recycling construction solid waste described in this utility model, by installing an inclined guide pipe at the top of the crushing chamber, can stagger the entry position of the material from the crushing chamber, thereby reducing the risk of fragments flying out of the top of the crushing chamber and causing injury to the operator when construction waste is being crushed.

[0014] 2. The crushing device for recycling construction solid waste described in this utility model uses a fan and an air inlet pipe to draw dust from the feed pipe into a fixed box for filtration, thereby reducing the dust generated during the crushing of construction waste from drifting to the outside, which could lead to environmental pollution and harm to the health of operators.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a crushing device for recycling construction solid waste includes a crushing chamber 1. A hopper 11 is located at the bottom of the crushing chamber 1, and a guide pipe 15 is installed at the top of the crushing chamber 1. The middle section of the guide pipe 15 has an inclined structure. A pair of crushing rollers 12 are installed inside the crushing chamber 1. A motor 13 is installed on the side wall of the crushing chamber 1. Gears 14 are installed at the ends of the crushing rollers 12. A dust removal component is provided on the side wall of the crushing chamber 1. A dirt removal component is provided at the bottom of the hopper 11. A material stabilizing component is provided at the top of the guide pipe 15. During operation, the motor 13 is started to drive the crushing rollers 12 and gears 14 to rotate. At this time, both sides... The gears 14 rotate in opposite directions, causing a pair of crushing rollers 12 to rotate in opposite directions. Construction solid waste is fed into the crushing chamber 1 through the feed pipe 15. At this time, the pair of crushing rollers 12 mesh with each other to crush the construction waste. The crushed construction waste is discharged from the hopper 11. When the construction waste splashes upward during crushing, it will be blocked by the inclined structure of the feed pipe 15. Through the above structure, the feed pipe 15 with the inclined structure installed at the top of the crushing chamber 1 can make the entry position of the material staggered from the crushing chamber 1, thereby reducing the situation where fragments of construction waste fly out from the top of the crushing chamber 1 during the crushing process and cause injury to the operator.

[0026] like Figures 1 to 4 As shown, the dust removal assembly includes a fixed box 2, which is installed on the side wall of the crushing chamber 1. An air inlet pipe 21 is connected to the side wall of the feed pipe 15, and the air inlet pipe 21 is connected to the top of the fixed box 2. A fan 22 is connected to the side wall of the fixed box 2. A cover plate 23 is installed on the side wall of the fixed box 2. A fixing assembly is provided on the side wall of the fixed box 2. A fixing plate 24 is slidably connected inside the fixed box 2. Multiple filter bags 25 are installed on the fixing plate 24. During operation, after the filter bags 25 are installed on the fixing plate 24, the fixing plate 24 is inserted into the slide rail inside the fixed box 2, and then the fixing assembly is used to fix the cover plate 23 to the fixed box 2. When the fan 22 is started, the airflow enters through the air inlet pipe 21. At this time, the dust generated during the crushing of construction waste is sucked into the fixed box 2 and filtered through multiple filter bags 25 inside the fixed box 2. Then, the fixed plate 24 and filter bags 25 can be removed from the fixed box 2 periodically, and the dust remaining inside the filter bags 25 can be cleaned. Then, the fixed plate 24 and filter bags 25 can be reinstalled in the fixed box 2. Through the above structure, the fan 22 and the air inlet pipe 21 draw the dust from the guide pipe 15 into the fixed box 2 for filtration, thereby reducing the dust generated during the crushing of construction waste from drifting to the outside, which could lead to environmental pollution and harm to the health of operators.

[0027] like Figure 3As shown, the fixing assembly includes a pair of baffles 3, which are hinged to the side wall of the fixing box 2. A pair of connecting shafts 31 are hinged to the side wall of the fixing box 2. A pressure ring 32 is threaded onto the connecting shaft 31, and a rotating wheel 33 is mounted on the pressure ring 32. During operation, after the cover plate 23 is installed at the opening of the fixing box 2, the baffles 3 are rotated to press the surface of the cover plate 23. Then, the connecting shafts 31 are rotated to enter the groove at the end of the baffles 3. Finally, the rotating wheel 33 is rotated to move the pressure ring 32 toward the surface of the baffles 3. When the pressure ring 32 and the baffles 3 are pressed together, the position of the baffles 3 can be fixed. At this time, the baffles 3 will press the cover plate 23 tightly at the opening of the baffles 3. The inner wall of the cover plate 23 will contact the fixing plate 24, thereby fixing the fixing plate 24 inside the fixing box 2. When it is necessary to remove the cover plate 23 and open the fixing box 2, the rotating wheel 33 can be rotated in the opposite direction to drive the pressure ring 32 away from the surface of the baffle 3. Then the connecting shaft 31 can be rotated out from the groove at the end of the baffle 3 to release the fixing of the baffle 3. After that, the cover plate 23 can be removed from the fixing box 2. Through the above structure, the connecting shaft 31, the pressure ring 32 and the rotating wheel 33 press the baffle 3 onto the surface of the cover plate 23. There is no need to use a lot of fastening bolts to fix it, which can facilitate the fixing and disassembly of the cover plate 23 on the fixing box 2, thereby facilitating the installation and disassembly of the fixing plate 24 and the filter bag 25 inside the fixing box 2.

[0028] like Figure 1 and Figure 5 As shown, the impurity removal component includes a pair of fixing bars 4, which are symmetrically fixed to the bottom of the hopper 11. A frame 41 is installed on the fixing bars 4, and a connecting component is provided on the fixing bars 4 and the frame 41. Multiple sets of barbs 42 are fixed on the frame 41. During operation, when the crushed material is discharged from the hopper 11, it will pass through the multiple sets of barbs 42. At this time, the multiple sets of barbs 42 can hook some flexible fragments of plastic or cloth in the crushed material. Through the above structure, the multiple sets of barbs 42 hook the plastic or cloth impurities in the crushed construction waste, thereby reducing the impurities in the crushed material and facilitating the reuse of the crushed material in the later stage.

[0029] like Figure 5 As shown, the connecting assembly includes two pairs of fixing posts 5, and the two sets of fixing posts 5 are respectively fixed to the top of a pair of fixing strips 4. The frame 41 has two sets of positioning holes 51. During operation, the height of the frame 41 is made to exceed the top of the positioning holes 51, and then the frame 41 is moved horizontally to the bottom of the hopper 11, and the positioning holes 51 are aligned with the fixing posts 5. Then the positioning holes 51 are fitted onto the fixing posts 5. At this time, the installation of the frame 41 and the barb 42 at the bottom of the hopper 11 is completed. Through the above structure, the fixing posts 5 and the positioning holes 51 fit together, which facilitates the installation and disassembly of the frame 41 and the barb 42 at the bottom of the hopper 11, and makes it convenient to remove the barb 42 to clean the hooked debris.

[0030] like Figure 1 As shown, the material stabilizing component includes a feeding hopper 6, which is fixed to the top of the guide pipe 15. During operation, when material is added into the guide pipe 15, the material enters the guide pipe 15 from the feeding hopper 6. Through the above structure, the feeding hopper 6 has a structure that is larger at the top and smaller at the bottom, which can reduce the situation where material falls to the outside when it is added.

[0031] like Figure 4 As shown, a sealing ring 7 is installed on the cover plate 23. The sealing ring 7 is located at the connection between the cover plate 23 and the fixed box 2. With the above structure, the sealing ring 7 is located at the connection between the cover plate 23 and the fixed box 2, which can improve the sealing between the fixed box 2 and the cover plate 23 and reduce air leakage.

[0032] Working principle: The starting motor 13 drives the crushing roller 12 and gear 14 to rotate. At this time, the gears 14 on both sides rotate in opposite directions, which causes the pair of crushing rollers 12 to rotate in opposite directions. Construction solid waste is fed into the crushing chamber 1 through the feed pipe 15. At this time, the pair of crushing rollers 12 mesh with each other to crush the construction waste. The crushed construction waste is discharged from the hopper 11. When the construction waste splashes upward during crushing, it will be blocked by the inclined structure of the feed pipe 15. After the filter bag 25 is installed on the fixing plate 24, the fixing plate 24 is inserted into the slide rail in the fixing box 2, and then the fixing assembly is used. Fix the cover plate 23 to the fixed box 2, start the fan 22 to drive the airflow into the air inlet pipe 21. At this time, the dust generated during the crushing of construction waste can be sucked into the fixed box 2 and filtered by multiple filter bags 25 inside the fixed box 2. Then, the fixed plate 24 and filter bags 25 can be removed from the fixed box 2 periodically, and the dust remaining inside the filter bags 25 can be cleaned. Then, the fixed plate 24 and filter bags 25 can be reinstalled in the fixed box 2. After the cover plate 23 is installed at the opening of the fixed box 2, the baffle 3 is rotated to press the surface of the cover plate 23, and then the connecting shaft 31 is rotated to enter the groove at the end of the baffle 3. Finally, rotate the wheel 33 to move the pressure ring 32 toward the surface of the baffle 3. When the pressure ring 32 and the baffle 3 are pressed together, the position of the baffle 3 can be fixed. At this time, the baffle 3 will press the cover plate 23 against the opening of the baffle 3. At this time, the inner wall of the cover plate 23 will contact the fixing plate 24, thereby fixing the fixing plate 24 in the fixing box 2. When it is necessary to remove the cover plate 23 and open the fixing box 2, the wheel 33 can be rotated in the opposite direction to move the pressure ring 32 away from the surface of the baffle 3. Then, the connecting shaft 31 can be rotated out of the groove at the end of the baffle 3 to release the fixation of the baffle 3. After that, the baffle 3 can be opened. The cover plate 23 is removed from the fixed box 2. When the crushed material is discharged from the feed hopper 11, it will pass through multiple sets of barbs 42. At this time, the multiple sets of barbs 42 can hook some flexible fragments of plastic or cloth in the crushed material, so that the height of the frame 41 exceeds the top of the positioning hole 51. Then the frame 41 is moved horizontally to the bottom of the feed hopper 11 and the positioning hole 51 is aligned with the fixed post 5. Then the positioning hole 51 is fitted onto the fixed post 5. At this time, the installation of the frame 41 and the barbs 42 at the bottom of the feed hopper 11 is completed. When the material is added into the guide pipe 15, the material enters the guide pipe 15 from the feed hopper 6.

[0033] 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 claimed utility model.
