Description

Technical Field

[0001] The present invention relates to the technical field of crushing equipment, and particularly relates to a waste concrete crushing equipment for concrete processing. Background Art

[0002] At present, with the rapid development of the construction industry, as one of the most widely used building materials, a large amount of waste concrete will be generated during the construction process. If these waste concretes are directly landfilled, not only will a large amount of land resources be occupied, but also environmental pollution may be caused. Crushing the waste concrete and reusing it to make recycled aggregates for new concrete production and other fields is an important way to achieve resource recycling and promote the development of green buildings. Therefore, waste concrete crushing equipment plays a key role in the industry.

[0003] However, the common waste concrete crushing equipment on the market at present has obvious technical defects. During the crushing process of the existing equipment, a classification cover is usually set to screen the crushed concrete particles to separate the particles that meet the particle size requirements. However, in the actual use process, due to the complex composition of waste concrete, the large particle concrete particles generated during crushing are extremely easy to adhere to the surface of the classification cover. As the working time increases, more and more large particle concrete particles adhere to the surface of the classification cover, which will block the classification holes on the classification cover. Once the classification holes are blocked, the small particle concrete particles cannot pass through the classification holes smoothly, resulting in the failure to effectively separate the qualified particles, reducing the processing efficiency of the equipment. In addition, the large particle concrete particles intercepted on the surface of the classification cover cannot be processed in time and cannot return to the crushing area for further crushing, making the crushing effect of waste concrete greatly reduced and difficult to meet the particle size requirements of recycled aggregates. To ensure the normal operation of the equipment, the operator needs to frequently stop the machine to manually clean the large particle concrete particles on the surface of the classification cover, resulting in poor crushing effect and low production efficiency of the existing crushing equipment, which urgently needs to be improved.

[0031] Referring to Figures 1 to 8 A further description is made of an embodiment of a waste concrete crushing device for concrete processing according to the present invention.

[0032] A waste concrete crushing device for concrete processing includes a crushing tank 1 and a control device 2 provided on the crushing tank 1. The interior of the crushing tank 1 is divided into an air inlet area 3, a crushing area 4, and a classification area 5 from bottom to top in sequence. The crushing tank 1 is provided with a feed pipe 6 communicating with the crushing area 4, and the crushing tank 1 is provided with a discharge pipe 7 communicating with the classification area 5. The crushing tank 1 is provided with a plurality of uniformly distributed air inlets 8 communicating with the air inlet area 3. An expanding pipe 9 fixedly connected to the inner wall of the crushing tank 1 is provided in the crushing area 4. A heater 28 electrically connected to the control device 2 is fixedly provided on the inner wall of the expanding pipe 9. The heater 28 is used to heat the gas in the ventilation area 12. It should be noted that by providing the heater 28, the heater 28 can heat the air flow passing through the ventilation area 12, so that the heated air flow can dry the concrete particles, which is beneficial to the subsequent processing of the concrete particles. At the same time, the setting of the heater 28 also heats the heat preservation cavity 16, so that the heat preservation cavity 16 can preliminarily dry the concrete blocks on the crushing grinding disc 15. A plurality of uniformly distributed connecting blocks 10 are fixedly provided on the inner wall of the expanding pipe 9. An expanding cover 11 fixedly connected to the connecting blocks 10 is provided in the expanding pipe 9. A ventilation area 12 is formed between the inner wall of the expanding pipe 9 and the outer wall of the expanding cover 11. It further includes: A crushing mechanism, provided on the crushing tank 1 and electrically connected to the control device 2, for crushing concrete blocks. The crushing mechanism includes: An annular carrier plate 13, fixedly provided in the expanding cover 11, and a plurality of uniformly distributed balls 14 are rotatably provided on the surface of the annular carrier plate 13 away from the air inlet area 3. It should be noted that by providing the annular carrier plate 13, the annular carrier plate 13 can provide a supporting force for the crushing grinding disc 15, thereby avoiding deformation of the crushing grinding disc 15 caused by long-term loading of concrete on the crushing grinding disc 15 to a certain extent. At the same time, the setting of the balls 14 greatly reduces the resistance suffered by the crushing grinding disc 15 during rotation, and improves the smoothness of rotation of the crushing grinding disc 15 to a certain extent.

[0033] The crushing grinding disc 15 is placed on the ball 14 and is rotatably connected to the expansion mask 11. The space formed by the crushing grinding disc 15 and the expansion mask 11 is the heat preservation cavity 16. The crushing grinding disc 15 is used to carry the concrete blocks entering the crushing area 4; The rotating part is arranged on the expansion mask 11 and is electrically connected to the control device 2. The rotating part is used to drive the crushing grinding disc 15 to rotate. The rotating part includes: The rotating motor 17 is fixedly arranged on the expansion mask 11 and is electrically connected to the control device 2; The rotating shaft 18 is rotatably arranged on the expansion mask 11. One end of the rotating shaft 18 close to the rotating motor 17 is fixedly connected to the output end of the rotating motor 17, and one end of the rotating shaft 18 close to the crushing grinding disc 15 is fixedly connected to the crushing grinding disc 15; The first motor cover 19 is fixedly arranged on the expansion mask 11.

[0034] There are three groups of crushing parts, and the three groups of crushing parts are evenly arranged on the crushing tank 1. The crushing parts are electrically connected to the control device 2. The crushing parts are used to cooperate with the crushing grinding disc 15 to crush the concrete blocks. The crushing parts include: The crushing motor 20 is fixedly arranged on the crushing tank 1 and is electrically connected to the control device 2; The crushing shaft 21 is rotatably arranged on the crushing tank 1. One end of the crushing shaft 21 close to the crushing motor 20 is fixedly connected to the output end of the crushing motor 20; The crushing grinding roller 22 is fixedly arranged at one end of the crushing shaft 21 extending into the crushing area 4. The crushing grinding roller 22 is used to cooperate with the crushing grinding disc 15 to crush the concrete blocks; The second motor cover 23 is fixedly arranged on the crushing tank 1.

[0035] During operation, the concrete blocks to be crushed are put in through the feeding pipeline 6, so that the concrete blocks to be crushed enter the crushing grinding disc 15 in the crushing area 4. Then, the rotating motor 17 and the crushing motor 20 are started through the control device 2. The start of the rotating motor 17 causes the rotating shaft 18 fixedly connected to the output end of the rotating motor 17 to rotate, and then drives the crushing grinding disc 15 fixedly connected to the rotating shaft 18 to rotate; the rotation of the crushing motor 20 causes the crushing shaft 21 fixedly connected to the output end of the crushing motor 20 to rotate, and then drives the crushing grinding roller 22 fixedly connected to the crushing shaft 21 to rotate. Through the cooperation between the crushing grinding roller 22 and the crushing grinding disc 15, the concrete blocks on the crushing grinding disc 15 are crushed into large and small concrete particles under the extrusion force and shear force.

[0036] The air supply mechanism is located in the air inlet area 3 and is electrically connected to the control device 2. The air supply mechanism is used to send the crushed concrete particles into the classification area 5. The air supply mechanism includes: The air supply duct 24 is fixedly arranged at one end of the flared pipe 9 close to the air inlet area 3, and the inside of the air supply duct 24 is communicated with the ventilation area 12; The ventilation carrier plate 25 is fixedly arranged inside the air supply duct 24. A air supply motor 26 electrically connected to the control device 2 is fixedly arranged on the ventilation carrier plate 25, and a air supply blade 27 is fixedly arranged on the output end of the air supply motor 26.

[0037] When the concrete block is crushed into large and small concrete particles, the heater 28 is controlled to start through the control device 2. The start of the heater 28 raises the temperature in the ventilation area 12, and then the air supply motor 26 is controlled to start through the control device 2, so that the air supply blade 27 fixedly connected to the output end of the air supply motor 26 rotates around the axis of the output end of the air supply motor 26. Furthermore, the air supply blade 27 continuously supplies air to the crushing area 4 through the air supply duct 24 and the ventilation area 12. The setting of the heater 28 raises the temperature of the air flow entering the crushing area 4, and the air flow entering the crushing area 4 drives the concrete particles to move towards the classification area 5; It should be noted that by providing the air supply mechanism, the device can convey the crushed concrete particles to the classification area 5. Through the cooperation of the air supply mechanism and the heater 28, the concrete blocks on the crushing grinding disc 15 and the crushed concrete particles can be dried at the same time, thereby improving the processing efficiency of the subsequent concrete particles.

[0038] The separation mechanism is arranged on the crushing tank 1 and is electrically connected to the control device 2. The separation mechanism is used to separate the crushed concrete particles. The separation mechanism includes: The classification cover 29 is located in the classification area 5 and is fixedly connected to the inner wall of the crushing tank 1. A plurality of uniformly distributed classification holes 30 are formed on the surface of the classification cover 29. A plurality of distributed first leakage grooves 31 are formed through the surface of the classification cover 29 close to the air inlet area 3, and a plurality of uniformly distributed arc grooves 32 are formed on the surface of the classification cover 29 away from the air inlet area 3; It should be noted that by providing the first leakage groove 31, the concrete particles that have not passed through the conical classification cover 37 in the classification cover 29 can leak out through the first leakage groove 31.

[0039] The conical frustum 33 is fixedly arranged inside the classification cover 29, and the axis of the conical frustum 33 coincides with the axis of the classification cover 29. By providing the conical frustum 33, the concrete particles that have not passed through the conical classification cover 37 in the classification cover 29 can move towards the direction of the first leakage groove 31, so as to facilitate the concrete particles that have not passed through the conical classification cover 37 to leak out through the first leakage groove 31; The reflux hood 34 is fixedly arranged at one end of the classification hood 29 far from the discharge pipeline 7. The reflux hood 34 is used to reflux the concrete particles leaking out of the first leakage trough 31. By arranging the reflux hood 34, the concrete particles leaking out of the first leakage trough 31 can move towards the third leakage trough 48; The grading part is arranged on the crushing tank 1 and is electrically connected to the control device 2. The grading part is used to grade the concrete particles entering the inside of the classification hood 29. The grading part includes: The grading motor 35 is arranged on the crushing tank 1 and is electrically connected to the control device 2; The grading shaft 36 is rotatably arranged on the crushing tank 1, and one end of the grading shaft 36 close to the grading motor 35 is fixedly connected to the output end of the grading motor 35; The conical grading hood 37 is fixedly arranged at one end of the grading shaft 36 far from the grading motor 35, and the end with a smaller diameter of the conical grading hood 37 extends into the classification hood 29.

[0040] When the concrete block is crushed into concrete particles, the control device 2 controls the grading motor 35 to start, so that the grading shaft 36 fixedly connected to the output end of the grading motor 35 rotates, thereby driving the conical grading hood 37 fixedly connected to the grading shaft 36 to rotate, so that the concrete particles entering the grading area 5 enter the inside of the classification hood 29 through the classification hood 29. The concrete particles entering the inside of the classification hood 29 are graded and screened by the conical grading hood 37, so that the concrete particles meeting the size requirements pass through the conical grading hood 37 and then enter the discharge pipeline 7 to be discharged from the crushing tank 1 and enter the subsequent processing procedures. The concrete particles that do not pass through the screening of the conical grading hood 37 fall onto the crushing grinding disc 15 in the lower crushing area 4 through the first leakage trough 31 and the third leakage trough 48 in sequence and are crushed again. In this way, the crushing and processing of the concrete block by this device are completed.

[0041] The cleaning part is arranged on the classification hood 29. The cleaning part is used to clean the concrete particles attached to the surface of the classification hood 29. The cleaning part includes: The annular ring 38 is located in the grading area 5. A plurality of uniformly distributed cleaning plates 39 are fixedly arranged on the inner surface of the annular ring 38. The cleaning plates 39 are used to clean the concrete particles attached to the surface of the classification hood 29; The arc-shaped rod 40 is fixedly arranged in the arc-shaped groove 32; There are a plurality of linkage blocks 41, and the plurality of linkage blocks 41 are uniformly penetrated through the annular ring 38. One end of the linkage block 41 close to the discharge pipeline 7 extends into the arc-shaped groove 32. The linkage block 41 is slidably connected to the arc-shaped rod 40. A hemispherical protrusion 42 is fixedly arranged at the end of the linkage block 41 far from the discharge pipeline 7; There are two first springs 43. The first springs 43 are sleeved on the arc-shaped rod 40, and the two first springs 43 are symmetrically distributed on both sides of the linkage block 41.

[0042] The transmission part is located in the crushing area 4 and is used to provide power for the cleaning part. The transmission part includes: Support columns 44, fixedly arranged on the crushing grinding disc 15, and the axis of the support column 44 coincides with the axis of the crushing grinding disc 15; A transmission disc 45, fixedly arranged at one end of the support column 44 close to the discharge pipe 7, and the axis of the transmission disc 45 coincides with the axis of the support column 44. A plurality of uniformly distributed built-in grooves 46 are formed on the surface of the transmission disc 45. A plurality of uniformly distributed second leakage grooves 47 penetrate through the surface of the transmission disc 45. A plurality of uniformly distributed third leakage grooves 48 penetrate through the surface of the transmission disc 45. It should be noted that the setting of the second leakage groove 47 enables the large concrete particles removed from the surface of the classification cover 29 to fall onto the crushing grinding disc 15 in the lower crushing area 4 through the second leakage groove 47. The setting of the third leakage groove 48 enables the concrete particles that have passed through the first leakage groove 31 but not passed through the conical grading cover 37 to fall onto the crushing grinding disc 15 in the lower crushing area 4 through the third leakage groove 48, so as to facilitate subsequent re-crushing and processing of the concrete particles; Sliding protrusions 49, slidably arranged in the built-in grooves 46; A second spring 50, arranged in the built-in groove 46, and the second spring 50 is always in a compressed state. The elastic coefficient of the second spring 50 is greater than the elastic coefficient of the first spring 43.

[0043] When the crushing grinding disc 15 rotates, it drives the support column 44 fixedly connected to the crushing grinding disc 15 to rotate, causing the transmission disc 45 fixedly connected to the support column 44 to rotate. Further, the sliding protrusion 49 provided on the transmission disc 45 rotates around the axis of the transmission disc 45. When the sliding protrusion 49 contacts the hemispherical protrusion 42, at this time, since the acting force of the second spring 50 on the sliding protrusion 49 is greater than the acting force of the first spring 43 on the linkage block 41, the linkage block 41 rotates by a certain angle around the axis of the classification cover 29. When the linkage block 41 rotates by a certain angle around the axis of the classification cover 29, it drives the annular ring 38 to rotate by a certain angle around the axis of the classification cover 29, so that the cleaning plate 39 provided on the annular ring 38 rotates by a certain angle around the axis of the classification cover 29. While the linkage block 41 rotates by a certain angle around the axis of the classification cover 29, the linkage block 41 also squeezes the first spring 43 in the rotation direction. When the acting force of the first spring 43 on the linkage block 41 after being squeezed is greater than the acting force of the second spring 50 on the sliding protrusion 49, at this time, the hemispherical protrusion 42 squeezes the sliding protrusion 49 into the built-in groove 46, so that the hemispherical protrusion 42 can pass through the sliding protrusion 49 in contact with it. After the hemispherical protrusion 42 passes through the sliding protrusion 49 in contact with it, the squeezed first spring 43 releases elastic potential energy, so that the linkage block 41 rotates reversely by a certain angle around the axis of the classification cover 29, and further the annular ring 38 drives the cleaning plate 39 to rotate reversely by a certain angle around the axis of the classification cover 29. In this way, through the cooperation of the sliding protrusion 49 and the hemispherical protrusion 42, the cleaning plate 39 can rotate reciprocally by a certain angle around the axis of the classification cover 29 on the surface of the classification cover 29, so as to remove the large particle concrete particles attached to the surface of the classification cover 29. The removed large particle concrete particles fall onto the crushing grinding disc 15 in the crushing area 4 below and are crushed again. In this way, the large particle concrete particles can enter the subsequent processing procedures through the conical grading cover 37; It should be noted that by providing a cleaning mechanism, the device can automatically remove the large particle concrete particles attached to the surface of the classification cover 29, thus avoiding that the small particle concrete particles cannot pass through the classification holes 30 on the classification cover 29 due to excessive concrete particles attached to the surface of the classification cover 29. The removed large particle concrete particles can fall onto the crushing grinding disc 15 in the crushing area 4 below and be crushed again until they meet the requirements, thus greatly improving the crushing effect of the device on concrete blocks.

[0044] Working principle: During operation, the concrete blocks to be crushed are fed through the feeding pipe 6, so that the concrete blocks to be crushed enter the crushing grinding disc 15 in the crushing area 4. Then, the control device 2 starts the rotating motor 17 and the crushing motor 20. The start of the rotating motor 17 causes the rotating shaft 18 fixedly connected to the output end of the rotating motor 17 to rotate, thereby driving the crushing grinding disc 15 fixedly connected to the rotating shaft 18 to rotate; the rotation of the crushing motor 20 causes the crushing shaft 21 fixedly connected to the output end of the crushing motor 20 to rotate, thereby driving the crushing grinding roller 22 fixedly connected to the crushing shaft 21 to rotate. Through the cooperation between the crushing grinding roller 22 and the crushing grinding disc 15, the concrete blocks on the crushing grinding disc 15 are crushed into concrete particles of various sizes under the action of extrusion force and shear force; When the concrete blocks are crushed into concrete particles of various sizes, the control device 2 controls the heater 28 to start. The start of the heater 28 raises the temperature in the ventilation area 12. Then, the control device 2 controls the air supply motor 26 to start, so that the air supply blade 27 fixedly connected to the output end of the air supply motor 26 rotates around the axis of the output end of the air supply motor 26. As a result, the air supply blade 27 continuously supplies air to the crushing area 4 through the air supply pipe 24 and the ventilation area 12. The setting of the heater 28 raises the temperature of the air flow entering the crushing area 4, and the air flow entering the crushing area 4 drives the concrete particles to move towards the classification area 5; When the concrete blocks are crushed into concrete particles, the control device 2 controls the classification motor 35 to start, so that the classification shaft 36 fixedly connected to the output end of the classification motor 35 rotates, thereby driving the conical classification cover 37 fixedly connected to the classification shaft 36 to rotate. This enables the concrete particles entering the classification area 5 to enter the interior of the classification cover 29 through the classification cover 29. The concrete particles entering the interior of the classification cover 29 are classified and screened by the conical classification cover 37. As a result, the concrete particles that meet the size requirements pass through the conical classification cover 37 and then enter the discharge pipe 7 to be discharged from the crushing tank 1 and enter the subsequent processing procedures. The concrete particles that do not pass through the screening of the conical classification cover 37 fall into the crushing grinding disc 15 in the lower crushing area 4 through the first leakage trough 31 and the third leakage trough 48 in sequence and are crushed again. This process is repeated, thus completing the crushing process of the concrete blocks by this device; When the crushing grinding disc 15 rotates, it drives the support column 44 fixedly connected to the crushing grinding disc 15 to rotate, causing the transmission disc 45 fixedly connected to the support column 44 to rotate. Furthermore, the sliding protrusion 49 provided on the transmission disc 45 rotates around the axis of the transmission disc 45. When the sliding protrusion 49 contacts the hemispherical protrusion 42, at this time, since the acting force of the second spring 50 on the sliding protrusion 49 is greater than the acting force of the first spring 43 on the linkage block 41, the linkage block 41 rotates by a certain angle around the axis of the classification cover 29. When the linkage block 41 rotates by a certain angle around the axis of the classification cover 29, it drives the annular ring 38 to rotate by a certain angle around the axis of the classification cover 29, so that the cleaning plate 39 provided on the annular ring 38 rotates by a certain angle around the axis of the classification cover 29. While the linkage block 41 rotates by a certain angle around the axis of the classification cover 29, the linkage block 41 also squeezes the first spring 43 in the rotation direction. When the acting force of the first spring 43 on the linkage block 41 after being squeezed is greater than the acting force of the second spring 50 on the sliding protrusion 49, at this time, the hemispherical protrusion 42 squeezes the sliding protrusion 49 into the built-in groove 46, so that the hemispherical protrusion 42 can pass through the sliding protrusion 49 in contact with it. When the hemispherical protrusion 42 passes through the sliding protrusion 49 in contact with it, the squeezed first spring 43 releases elastic potential energy, so that the linkage block 41 rotates in the reverse direction by a certain angle around the axis of the classification cover 29. Furthermore, the annular ring 38 drives the cleaning plate 39 to rotate in the reverse direction by a certain angle around the axis of the classification cover 29. Repeating this way, through the cooperation of the sliding protrusion 49 and the hemispherical protrusion 42, the cleaning plate 39 can rotate reciprocally by a certain angle around the axis of the classification cover 29 on the surface of the classification cover 29, so as to remove the large particle concrete particles attached to the surface of the classification cover 29. The removed large particle concrete particles fall onto the crushing grinding disc 15 in the crushing area 4 through the second leakage groove 47 below and are crushed again. Repeating this way, the large particle concrete particles can enter the subsequent processing procedures through the conical grading cover 37.
