Description

Technical Field

[0001] The present invention belongs to the technical field of building aggregate processing, and particularly relates to a multi-stage processing device based on the reuse of building aggregates. Background Art

[0002] In the construction industry, the reuse of building aggregates is an important way to achieve resource recycling. The crushing process of aggregates is a key step in the reuse process, which directly affects the quality of aggregates and subsequent applications. Traditional aggregate crushing equipment usually includes jaw crushers, cone crushers, impact crushers, etc. Although these devices can meet the aggregate crushing requirements to a certain extent, there are some problems in the actual operation process. For example, the equipment is prone to jamming, resulting in reduced production efficiency and increased maintenance costs. The jamming phenomenon usually occurs between the crushing rollers. When the aggregate size is too large or the shape is irregular, it is easy to get stuck between the two crushing rollers, causing the equipment to stop running. To solve this problem, existing technologies have taken various measures, such as adding overload protection devices and using hydraulic systems. However, these methods either cannot fundamentally solve the jamming problem or increase the complexity and cost of the equipment. In view of the above problems, the present invention proposes a multi-stage processing device based on the reuse of building aggregates. Summary of the Invention

[0003] The purpose of the present invention is to provide a multi-stage processing device based on the reuse of building aggregates, which can move one of the crushing rollers left and right when the aggregate is stuck between the two crushing rollers, so that the aggregate falls or is crushed, thereby preventing the two crushing rollers from jamming, and further improving the crushing efficiency.

A first motor is installed on the outer side of the crushing box, and the output end of the first motor is connected to the first rotating roller. An anti-jamming component is installed between the first rotating roller and the second rotating roller, and the anti-jamming component is used to prevent jamming between the two crushing rollers. A filter screen is installed inside the filter box. A discharge empty groove is provided on one side of the filter box and on one side of the filter screen. A lifting structure is provided on the outside of the filter box at a position corresponding to the discharge empty groove.

The fixed rotating frame is rotatably connected to the crushing box. One end of the second rotating roller far from the inclined cutting surface and the pointed cone part is provided with a telescopic rod. Fixing pieces are fixed at both ends of the telescopic rod. One of the fixing pieces close to the second rotating roller end of the telescopic rod is fixedly connected to the second rotating roller. A first mounting frame is fixed on the outside of the crushing box. And the first mounting frame is fixedly connected to the other fixing piece. A second spring is installed between the two fixing pieces and on the outside of the telescopic rod. An adjusting structure is installed inside the sliding rod.

[0015] In order to make the purpose and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the scope of protection specifically claimed by the present invention.

[0016] As Figures 1 - 6 shown, a multi-stage treatment device based on the reuse of construction aggregates includes a filter box 1. A crushing box 2 is installed on the top of the filter box 1, and the interiors of the filter box 1 and the crushing box 2 are connected. Inside the crushing box 2, a first rotating roller 3 and a second rotating roller 4 are rotatably connected. At both ends of a crushing roller 5 located outside the second rotating roller 4 inside the crushing box 2, blocking pieces 35 are fixed. Through the arrangement of the blocking pieces 35, when the aggregates enter the crushing box 2, the aggregates at both ends of the top of the second rotating roller 4 can be blocked by the blocking pieces 35, preventing the aggregates from falling through the gaps at both ends of the crushing roller 5 outside the second rotating roller 4. And a crushing roller 5 is fixed on the outside of the first rotating roller 3 and the second rotating roller 4 inside the crushing box 2. Gears 7 are also installed on the outside of the first rotating roller 3 and the second rotating roller 4, and the two gears 7 are meshed. A first motor 6 is installed on the outside of the crushing box 2. The outside of the crushing box 2 can be installed with a connecting plate, and the first motor 6 is installed through the connecting plate. And the output end of the first motor 6 is connected to the first rotating roller 3; Put the aggregates that need to be reused on the construction site into the crushing box 2, start the first motor 6, so that the output end of the first motor 6 drives the first rotating roller 3 to rotate, and drives the gear 7 outside the other second rotating roller 4 to rotate through the gear 7 outside the first rotating roller 3, thereby driving the first rotating roller 3 and the second rotating roller 4 to rotate in opposite directions, and then driving the two crushing rollers 5 to rotate in opposite directions, so that the crushing rollers 5 crush the aggregates. The crushed aggregates enter the filter box 1 for the next step; An anti-jamming component is installed between the first rotating roller 3 and the second rotating roller 4, and the anti-jamming component is used to prevent jamming between the two crushing rollers 5; Refer to the appendix Figure 3 , the anti-jamming component includes a fixing rod 9 fixed on the outer side of the first rotating roller 3, a sliding rod 10 is slidably connected to the outer side of the fixing rod 9, and an inclined cutting cone part 15 is arranged at one end of the second rotating roller 4 close to the sliding rod 10; An adjusting structure is installed in the sliding rod 10, and the adjusting structure is used to adjust the overall length of the fixing rod 9 and the sliding rod 10; Refer to the appendix Figure 4 , the adjusting structure includes an installation cavity 11 arranged inside the sliding rod 10, the fixing rod 9 is slidably connected in the installation cavity 11, a first electromagnet 12 is installed at one end of the installation cavity 11 away from the fixing rod 9, and a magnet is fixed at one end of the fixing rod 9 close to the first electromagnet 12. The magnetic poles on the sides of the first electromagnet 12 and the magnet close to each other are the same. If the magnetic pole at the position where the first electromagnet 12 is close to the magnet is the N pole, then the magnetic pole at the position where the magnet is close to the first electromagnet 12 is also the N pole. A middle mounting plate 14 is fixed between the fixing rod 9 and the first electromagnet 12 in the installation cavity 11, and a first spring 13 is installed between the fixing rod 9 and the middle mounting plate 14.

[0017] When it is necessary to adjust the total length of the fixing rod 9 and the sliding rod 10, the first electromagnet 12 can be started, so that the first electromagnet 12 emits magnetic force and drives the sliding rod 10 to slide in a direction away from the fixing rod 9, thereby stretching the first spring 13. When the length of the fixing rod 9 and the sliding rod 10 is not required to be too long, the first electromagnet 12 can be turned off, so that the pulling force of the first spring 13 pulls the sliding rod 10 closer to the fixing rod 9; The gear 7 located outside the first rotating roller 3 is fixedly connected to the first rotating roller 3. The gear 7 located outside the second rotating roller 4 is slidably connected to the second rotating roller 4. A limiting strip is fixed outside the second rotating roller 4. The gear 7 is slidably connected outside the limiting strip and the second rotating roller 4, thereby restricting the gear 7 located outside the second rotating roller 4 to rotate along with the second rotating roller 4 when the second rotating roller 4 slides. A fixed rotating frame 8 is fixed on one side of the gear 7 located outside the second rotating roller 4 close to the crushing chamber 2. The fixed rotating frame 8 is used to restrict the gear 7. Through the setting of the fixed rotating frame 8, when the second rotating roller 4 moves left and right, it is always in a stable state and always meshes with the other gear 7. The fixed rotating frame 8 is rotatably connected to the crushing chamber 2. One end of the second rotating roller 4 far from the inclined plane cone part 15 is provided with a telescopic rod 16. The telescopic rod 16 is composed of a thin rod and a thick rod slidably arranged outside the thin rod. Fixed pieces 17 are fixed at both ends of the telescopic rod 16. One fixed piece 17 close to the second rotating roller 4 of the telescopic rod 16 is fixedly connected to the second rotating roller 4. A first mounting frame 19 is fixed outside the crushing chamber 2, and the first mounting frame 19 is fixedly connected to the other fixed piece 17. A second spring 18 is installed between the two fixed pieces 17 and outside the telescopic rod 16; When the first rotating roller 3 rotates, it can drive the sliding rod 10 to rotate. When the crushing roller 5 is stuck, the control first electromagnet 12 can be made to emit magnetic force, thereby driving the sliding rod 10 to move away from the fixed rod 9, so that the total length of the fixed rod 9 and the sliding rod 10 increases, so that the sliding rod 10 and the inclined plane cone part 15 can come into contact with each other. Then when the sliding rod 10 rotates to, it can contact the inclined plane cone part 15 and the sliding rod 10 does not stop rotating, so that the inclined plane cone part 15 moves toward the side close to the crushing roller 5, thereby driving the second rotating roller 4 and the crushing roller 5 thereon to move accordingly and compressing the second spring 18. When the sliding rod 10 rotates to not contact the inclined plane cone part 15, the second spring 18 can drive the second rotating roller 4, the crushing roller 5 on the second rotating roller 4 and the inclined plane cone part 15 to reset through stretching. In a cycle of the left and right movement of the crushing roller 5, the device can repeat this cycle until the aggregate on the two crushing rollers 5 falls off or is crushed. Through this setting, the device can prevent the two crushing rollers 5 from being stuck.

[0018] Inside the filter box 1, a filter screen 20 is installed. On one side of the filter box 1 and on one side of the filter screen 20, there is a discharge empty groove 24. After the aggregate is crushed, it falls onto the filter screen 20. The smaller aggregate passes through the filter screen 20 and falls to the bottom of the filter box 1 for collection. While the larger aggregate inclines and is arranged downward on the side of the filter screen 20 close to the discharge empty groove 24, and then rolls towards the direction of the discharge empty groove 24 and falls onto the following lifting structure. On the outside of the filter box 1 and at the position corresponding to the discharge empty groove 24, there is a lifting structure, which is used to lift the uncrushed aggregate back to the crushing box 2 for re-crushing.

[0019] Refer to the appendix Figure 5 Inside the filter box 1 and at the bottom of the filter screen 20, a bottom fixing frame 21 is fixed. Between the bottom fixing frame 21 and the filter screen 20, third springs 22 are evenly arranged. On the top of the bottom fixing frame 21, second electromagnets 23 are evenly arranged. And at the position corresponding to the second electromagnets 23 on the bottom of the filter screen 20, there are iron sheets. When falling onto the filter screen 20, through the setting of the third springs 22, the filter screen 20 can slide downward, and shock absorption is carried out through the third springs 22 to buffer the impact force of the aggregate on the filter screen 20. And by starting the second electromagnets 23, the second electromagnets 23 adsorb the iron sheets, causing the filter screen 20 to move downward. At this time, the second electromagnets 23 can be turned off, and the filter screen 20 is reset through the setting of the third springs 22. Then, by starting the second electromagnets 23 reciprocally, a vibration effect appears on the filter screen 20, making it more convenient for the aggregate on the filter screen 20 to roll into the lifting structure along the inclination of the filter screen 20.

[0020] Refer to the appendix Figure 6 Refer to the appendix When the aggregate rolls onto the bearing platform 29, a second mounting frame 31 can be fixed to the bottom of the bearing platform 29. A hydraulic cylinder 32 is installed inside the second mounting frame 31, and a blocking plate 33 is vertically and upwardly fixed to the stroke rod of the hydraulic cylinder 32. The blocking plate 33 passes through the bearing platform 29 and extends to the top of the bearing platform 29. Then, by starting the hydraulic cylinder 32, the blocking plate 33 is driven to move upward to block the aggregate in the bearing platform 29. And the second motor 26 is started, so that the output end of the second motor 26 drives the threaded rod 27 to rotate. Due to the threaded connection between the threaded rod 27 and the bearing platform 29, and the sliding connection between the bearing platform 29 and the guide rod 28, the bearing platform 29 moves upward until it is aligned with the material guiding platform 34. At this time, the hydraulic cylinder 32 can be started again to make the stroke rod of the hydraulic cylinder 32 retract and drive the blocking plate 33 to retract. The aggregate in the bearing platform 29 rolls again along the inclined plane 30 and the material guiding platform 34 into the crushing box 2, and is crushed again by the two crushing rollers 5.

[0021] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
