Technical Field

[0001] This invention relates to the technical field of construction waste crushing, and more specifically, to a mobile crushing method for construction waste. Background Technology

[0002] During the construction and demolition process, a large amount of construction waste, such as excavated soil, slag, and discarded materials, is generated.

[0003] In the existing technology, due to the huge volume of construction waste, the limited capacity of construction waste disposal sites, and the lack of corresponding recycling measures, it is difficult to effectively treat construction waste. The long-term accumulation of construction waste occupies a large amount of land and easily causes serious pollution and ecological damage to soil, rivers, vegetation, and atmosphere. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile crushing method for construction waste, which aims to solve the problems in the prior art where the amount of construction waste is huge and difficult to process, and the resources are difficult to be effectively utilized.

[0005] This invention is implemented as follows: a mobile crushing method for construction waste includes the following construction steps:

[0006] 1) Collect construction waste, manually sort the construction waste, remove household garbage, steel bars, plastics, and wood blocks to form materials to be crushed;

[0007] 2) A mobile crusher is provided, comprising a frame, a track for movement at the bottom of the frame, an impact crusher on the frame, the impact crusher having a crushing chamber, a crushing zone and an impact zone in the crushing chamber, a rotating hammer in the crushing zone and an impact liner in the impact zone; the top of the crushing chamber has an inlet for the material to be crushed to enter the crushing chamber, and the bottom of the crushing chamber has an outlet for the crushed material to be discharged;

[0008] Move the mobile crusher to the designated position;

[0009] 3) The loader's bucket is used to transport the material to be crushed upwards to the top of the feed inlet and dump the material to be crushed out. After the material to be crushed rolls downwards into the crushing chamber, the hammer strikes and crushes the material to be crushed, and the material flies out of the crushing zone and hits the impact liner. The impact liner bounces the material to be crushed back into the crushing zone for multi-stage crushing to form recycled material.

[0010] The frame is also equipped with a discharge belt, through which the recycled material is discharged onto the discharge belt, and the discharge belt transports the recycled material to the accumulation area outside the crusher.

[0011] Optionally, the front end of the frame is provided with a hopper for accommodating construction waste, the hopper is arranged above the inlet, and a main chute is provided between the hopper and the inlet;

[0012] In step 3), the bucket pours the material to be crushed into the feed hopper, and the material to be crushed rolls down the main chute into the crushing chamber.

[0013] Optionally, the main chute is provided with multiple horizontal plates, which are arranged at intervals along the extension direction of the main chute to form an upper and lower gap; in step 3), the material to be crushed that enters the main chute rolls onto the horizontal plates and continues to roll downwards, while small particles in the material to be crushed that are within the set range are separated from the main chute through the upper and lower gaps.

[0014] Optionally, there is a side gap between the two sides of the horizontal plate and the two side walls of the main chute; in step 3), as the material to be crushed enters the main chute and rolls onto the horizontal plate and continues to roll downwards, small particles in the material to be crushed with a particle size within a set range are separated from the main chute through the side gap.

[0015] Optionally, the horizontal plate has a hollowed-out installation area in the middle, and an installation frame is fixedly installed in the installation area. The installation frame is provided with an internal screen, and the internal screen has multiple internal screen holes.

[0016] In step 3), the material to be crushed that enters the main chute rolls onto the horizontal plate and continues to roll downwards. Small particles in the material to be crushed that are within the set range of particle size are separated from the main chute through the screen holes inside the plate.

[0017] Optionally, a side chute is provided below the horizontal plate, and the end of the side chute is connected to the discharge port; the side chute is provided with a plurality of inclined plates arranged at intervals, and the inclined plates are arranged inclined toward the discharge port.

[0018] In step 3), small particles, separated by upper and lower gaps, side gaps, and screen holes inside the plate, fall onto the inclined plate under the action of gravity and roll down along the inclined direction of the inclined plate to the discharge port. The small particles are mixed with the recycled material falling from the discharge port.

[0019] Optionally, the frame is equipped with a magnetic separator, which is arranged above the discharge belt; the discharge belt extends upward at an angle along the transport direction of the discharge belt; in step 3), during the forward transport of the recycled material through the discharge belt, the magnetic separator separates magnetic substances from the recycled material.

[0020] Optionally, the middle part of the impact liner protrudes outward from the crushing zone and is bent; the impact liner is connected to a telescopic rod, and the end of the telescopic rod is fixedly connected to the impact liner; the impact liner has an impact sidewall facing the crushing zone, and a filter gap is formed between the bottom of the impact sidewall and the crushing zone.

[0021] By extending and retracting the telescopic rod, the width of the filter interval is changed, and the recycled material formed by crushing the material to be crushed is discharged from the outlet through the filter interval.

[0022] Optionally, the crushing zone is provided with multiple concentric rotating hammers, which are fixedly connected to the rotating disk and are evenly spaced along the circumference of the rotating disk.

[0023] Optionally, the impact sidewall has multiple upwardly protruding strips, which extend along the width direction of the impact sidewall and are spaced apart along the length direction of the impact sidewall. The ends of the protruding strips are pointed. There is an elastic gap between adjacent protruding strips, and the elastic gap is filled with an elastic rubber strip, which extends along the length direction of the elastic gap. The elastic rubber strip is fixedly embedded in the elastic gap, and the top of the elastic rubber strip is higher than the top of the protruding strip.

[0024] When small pieces of broken material, launched by the hammer, strike the elastic strip, the elastic strip deforms under pressure. Under the action of elastic force, the small pieces of broken material rebound back into the crushing zone for further crushing. When large pieces of broken material, launched by the hammer, strike the elastic strip, the elastic strip deforms under pressure until the large pieces of broken material strike the end of the protruding strip. The large pieces of broken material then break into multiple pieces under pressure, and under the action of elastic force, the pieces of broken material rebound back into the crushing zone for further crushing.

[0025] Compared with existing technologies, the mobile crushing method for construction waste provided by this invention first involves manually sorting the construction waste to remove impurities and form materials to be crushed. Then, the mobile crusher is moved to the material storage area, and the material is fed in using the bucket of a loader. The impact crusher crushes the material multiple times to form recycled material, which is then discharged to the storage area via a discharge belt. In this way, the mobile crusher is moved by a tracked vehicle to crush materials in multiple storage areas, greatly improving the crushing efficiency. At the same time, the multiple crushing by the impact crusher greatly improves the crushing quality.

[0026] The recycled materials formed from crushing can be used as base fillers in road construction and in the production of environmentally friendly bricks, thus recycling construction waste and promoting green environmental protection. The comprehensive utilization of recycled construction waste materials can alleviate the pressure of handling construction waste generated during urban renewal, save land space for construction waste disposal sites, and indirectly promote urban development. At the same time, it can reduce the mining of natural sand and gravel, alleviating the increasingly scarce resources and the damage to the ecological environment, resulting in significant social benefits.

[0035] Reference Figure 1-5 The image shows a preferred embodiment of the present invention.

[0036] The mobile crushing method for construction waste provided by this invention includes the following construction steps:

[0037] 1) Collect construction waste, manually sort the construction waste, remove household garbage, steel bars, plastics, and wood blocks to form materials to be crushed;

[0038] 2) A mobile crusher is provided. The mobile crusher includes a frame with a track at the bottom. An impact crusher 200 is mounted on the frame. The impact crusher 200 has a crushing chamber with a crushing zone and an impact zone. A rotating hammer 211 is mounted in the crushing zone, and an impact liner 220 is mounted in the impact zone. The top of the crushing chamber has an inlet 201 for the material to be crushed to enter the crushing chamber, and the bottom of the crushing chamber has an outlet 202 for the crushed material to be discharged.

[0039] Move the mobile crusher to the designated location;

[0040] 3) The bucket of the loader is used to transport the material to be crushed upward to the top of the feed inlet 201 and dump the material to be crushed. After the material rolls downward into the crushing chamber, the hammer 211 strikes and crushes the material to be crushed. The material flies out of the crushing zone and hits the impact liner 220. The impact liner 220 bounces the material to be crushed back into the crushing zone for multi-stage crushing to form recycled material.

[0041] The frame is also equipped with a discharge belt 300. The recycled material is discharged through the discharge port 202 onto the discharge belt 300, which transports the recycled material to the accumulation area outside the crusher.

[0042] The mobile crushing method for construction waste described above first involves manually sorting the construction waste to remove impurities and form materials to be crushed. Then, the mobile crusher is moved to the material storage area, and the material is fed in using the bucket of a loader. The impact crusher 200 crushes the material multiple times to form recycled material, which is then discharged to the storage area via the discharge belt 300. In this way, the mobile crusher can move via tracks and crush materials in multiple storage areas, greatly improving crushing efficiency. At the same time, the multiple crushing operations of the impact crusher 200 greatly improve the crushing quality.

[0043] The recycled materials formed from crushing can be used as base fillers in road construction and in the production of environmentally friendly bricks, thus recycling construction waste and promoting green environmental protection. The comprehensive utilization of recycled construction waste materials can alleviate the pressure of handling construction waste generated during urban renewal, save land space for construction waste disposal sites, and indirectly promote urban development. At the same time, it can reduce the mining of natural sand and gravel, alleviating the increasingly scarce resources and the damage to the ecological environment, resulting in significant social benefits.

[0044] Specifically, the front end of the frame is provided with a hopper 100 for holding construction waste. The hopper 100 is arranged above the inlet 201, and a main chute 101 is provided between the hopper 100 and the inlet 201.

[0045] In step 3), the bucket pours the material to be crushed into the feed hopper 100, and the material to be crushed rolls down the main chute 101 at an angle into the crushing chamber.

[0046] Specifically, the main chute 101 is provided with multiple horizontal plates 110. Along the extending direction of the main chute 101, the multiple horizontal plates 110 are arranged at intervals, forming upper and lower gaps 111. In step 3), the material to be crushed entering the main chute 101 rolls onto the horizontal plates 110 and continues to roll downwards. Small particles within a set size range in the material to be crushed are separated from the main chute 101 through the upper and lower gaps 111. Thus, as... Figure 1 As shown, the arrangement of multiple horizontal plates 110 forms an inclined main chute 101, and there are vertical gaps 111 between the horizontal plates 110. During the process of the material to be crushed rolling down, small particles in the material to be crushed can leave the main chute 101 through the vertical gaps 111. The size of the vertical gaps 111 can be changed by changing the position of the horizontal plates 110.

[0047] The horizontal plate 110 has side gaps 112 between its two sides and the side walls of the main chute 101. In step 3), the material to be crushed that enters the main chute 101 rolls onto the horizontal plate 110 and continues to roll downwards. Small particles within a set size range in the material to be crushed are separated from the main chute 101 through the side gaps 112. In this way, the side gaps 112 on both sides can satisfy the requirement for small particles in the material to be crushed to leave the main chute 101, greatly improving the crushing quality.

[0048] The horizontal plate 110 has a hollowed-out installation area in the middle, and an installation frame 130 is fixedly installed in the installation area. The installation frame 130 is provided with an inner plate screen 131, and the inner plate screen 131 is provided with multiple inner plate screen holes.

[0049] In step 3), the material to be crushed, which enters the main chute 101, rolls onto the horizontal plate 110 and continues to roll downwards. During this process, small particles within the set range of particle size in the material to be crushed are separated from the main chute 101 through the screen holes inside the plate. In this way, the screen 131 inside the plate can be quickly replaced by replacing the mounting frame 130, which improves crushing efficiency and crushing quality.

[0050] A side chute 102 is provided below the horizontal plate 110, and the end of the side chute 102 is connected to the discharge port 202; a plurality of inclined plates 120 are arranged at vertical intervals 111 on the side chute 102, and the inclined plates 120 are arranged inclined toward the discharge port 202.

[0051] In step 3), small particles, passing through the upper and lower gaps 111, the side gaps 112, and the screen holes inside the plate, fall onto the inclined plate 120 under the influence of gravity and roll downwards along the inclined direction of the inclined plate 120 to the discharge port 202. The small particles mix with the recycled material falling from the discharge port 202. In this way, the material can directly roll onto the discharge belt 300 through the side chute 102, improving crushing efficiency and crushing quality.

[0052] A magnetic separator 310 is installed on the frame and positioned above the discharge belt 300. The discharge belt 300 extends upwards at an angle along the transport direction of the discharge belt. In step 3), as the recycled material is transported forward through the discharge belt 300, the magnetic separator 310 separates magnetic materials from the recycled material. This process removes reinforcing bars and iron filings from the recycled material, ensuring quality.

[0053] In this embodiment, the middle part of the impact liner 220 protrudes outward from the crushing zone and is bent. The impact liner 220 is connected to a telescopic rod 221, and the end of the telescopic rod 221 is fixedly connected to the impact liner 220. The impact liner 220 has an impact sidewall facing the crushing zone, and a filter gap 203 is formed between the bottom of the impact sidewall and the crushing zone.

[0054] The width of the filter gap 203 is changed by extending the telescopic rod 221, and the recycled material formed by crushing the material is discharged from the outlet 202 through the filter gap 203. Thus, referring to... Figure 1 As shown, the maximum particle size can be controlled by changing the size of the filter interval 203.

[0055] The crushing zone is equipped with multiple concentric rotating hammers 211, which are fixedly connected to the rotating disk 210 and are evenly spaced along the circumference of the rotating disk 210.

[0056] The impact sidewall has multiple upward-protruding strips 222, which extend along the width of the impact sidewall and are spaced apart along the length of the impact sidewall. The ends of the strips 222 are sharp. There is an elastic gap between adjacent strips 222, and the elastic gap is filled with an elastic rubber strip 223, which extends along the length of the elastic gap. The elastic rubber strip 223 is fixedly embedded in the elastic gap, and the top of the elastic rubber strip 223 is higher than the top of the strips 222.

[0057] When small pieces of crushed material, launched by the hammer 211, hit the elastic strip 223, the elastic strip 223 deforms under force. Under the action of elastic force, the small pieces of crushed material rebound back into the crushing zone for further crushing. When large pieces of crushed material, launched by the hammer 211, hit the elastic strip 223, the elastic strip 223 deforms under force until the large pieces of crushed material hit the end of the protruding strip 222. The large pieces of crushed material break into multiple pieces under force, and under the action of elastic force, the pieces of crushed material rebound back into the crushing zone for further crushing.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
