TECHNICAL FIELD

[0001] The present application relates to the technical field of building waste recycling, in particular to a building solid waste crushing equipment. BACKGROUND

[0002] The existing building solid waste crushing equipment has the following problems: firstly, the automatic process of returning the material for secondary crushing is insufficient, time-consuming and labor-intensive, and there is a safety hazard; secondly, the screening efficiency of the crushed waste is low and easy to block, and the dust pollution control in the crushing process is weak.

[0003] CN202110359034.X discloses a zinc oxide dust removal device, which comprises a shell, a crushing assembly and a dust removal assembly; the shell comprises a feeding cavity and a dust removal cavity connected below the feeding cavity; the crushing assembly is arranged in the feeding cavity and comprises a crushing roller; the dust removal assembly is detachably installed in the dust removal cavity and comprises a dust adsorption element and a zinc oxide crushing and screening device. The zinc oxide dust removal device has a simple and reasonable structure, and uses negative pressure to adsorb the dust generated during the downward falling of the zinc oxide crushing material to the adsorption filter membrane, and at the same time, a cooling water spraying device sprays low-temperature spray to the adsorption filter membrane, so that the adsorbed dust is deposited on the surface of the adsorption filter membrane under the action of low-temperature and low-humidity environment, and will not diffuse through the filter membrane to the third space and the second space, which can effectively protect the cleanliness of other equipment, and cooperate with the timely flushing of the backwashing device. However, the unfiltered zinc oxide crushing material falls into the zinc oxide crushing material recovery box, and then the device needs to be stopped, and the entire screening device needs to be pulled out manually to take out the crushing material for secondary crushing. When the adsorption filter membrane is backwashed, the generated sewage accumulates in the first space, which needs special discharge treatment. SUMMARY

[0007] Furthermore, the crushing mechanism includes two sets of crushing transmission gears driven by the crushing drive motor and meshing with each other. Each set of crushing transmission gears is fixed on a transmission shaft, and the two transmission shafts are symmetrically and rotatably arranged inside the crushing device housing. Multiple sets of crushing blades are fixed on each transmission shaft, and the cutting edges of the crushing blades on the two sets of transmission shafts are opposite to each other and staggered. Multiple sets of baffles are also provided inside the crushing device housing, evenly inserted on both sides of the crushing blades.

[0008] Furthermore, the transfer mechanism includes a transfer mechanism housing, which is connected to the outer shell of the recycling device on both sides via second electric telescopic rods; a guide baffle is fixed below the transfer mechanism housing, and the guide baffle is slidably engaged with the outer shell of the screening device and the outer shell of the recycling device; a third electric telescopic rod is fixed inside the transfer mechanism housing via a support rod, and a pusher plate that can slide inside the transfer mechanism housing is fixed at the end of the third electric telescopic rod; a limiting block is provided on the side of the transfer mechanism housing near the crushing device.

[0009] Furthermore, the guide shield can block the material dispensing port when the transfer mechanism moves upward.

[0010] Furthermore, four sets of auxiliary blocks are symmetrically arranged on both sides of the screening plate. The auxiliary blocks are slidably connected to the housing of the screening device, and buffer springs are connected to both the upper and lower sides of the auxiliary blocks. Four sets of vibration motors are fixed at the bottom of the screening plate, and the other end of the vibration motors is fixed inside the housing of the screening device. A guide plate is provided at the bottom of the housing of the screening device.

[0011] Furthermore, the transmission mechanism includes a transmission drive motor fixed to the housing of the recycling device, and the output end of the transmission drive motor is sequentially connected to a first sprocket and a first pulley; the first sprocket meshes with a second sprocket via a chain, and a second pulley is fixed on the second sprocket; a conveyor belt is meshed between the first pulley and the second pulley; a flushing pipe facing the conveyor belt and a discharge scraper inclined and with its end in contact with the conveyor belt are also fixed inside the housing of the recycling device.

[0012] Furthermore, the water mist nozzles of the spray pipe are symmetrically distributed on both sides of the discharge port; the flushing pipe is equipped with two sets of water flow nozzles, one set facing the conveyor belt and the other set facing the bottom surface of the recycling device housing.

[0013] Furthermore, one end of the outer casing of the recycling device is provided with a drain outlet, and the bottom of the outer casing of the recycling device is an inclined surface that slopes toward the drain outlet.

[0014] Furthermore, the inclination angle of the screen plate is 30°.

[0015] Compared with the prior art, the present invention has the following advantages: (1) Automated closed-loop crushing is achieved, which is both efficient and safe. The transfer mechanism realizes the automatic return of large pieces of crushed material and the closed-loop secondary crushing. Traditional equipment requires manual re-feeding of insufficiently crushed material, which is time-consuming, labor-intensive, and poses safety hazards. However, this equipment drives the housing of the transfer mechanism to move upward along the track through the second electric telescopic rod, and the pusher plate pushes the large pieces of crushed material back to the crushing device. The whole process does not require manual intervention. This greatly reduces the labor input and improves the processing efficiency.

[0016] (2) High screening efficiency and effective anti-clogging. The screening device improves the reliability and efficiency of screening. The inclined screen plate generates high-frequency micro-amplitude vibration under the drive of four sets of vibrating motors. With the stabilizing effect of auxiliary blocks and buffer springs, it can not only accelerate the separation of fine powder, but also effectively prevent large pieces of material from clogging the screen, ensuring the continuous and stable operation of the production line.

[0017] (3) Excellent dust control. To address the severe dust problem during the crushing process, this invention incorporates multi-stage dust suppression measures in the recycling device. Spray pipes located on both sides of the feed inlet can adsorb dust at its source, achieving rapid dust reduction. Simultaneously, the humidified conveyor belt can better adsorb the settled powdery waste. This integrated dust suppression design reduces the dust concentration in the working environment and improves the operating conditions for workers.

[0018] (4) Strong crushing force and uniform output particle size. The crushing device adopts a dual-shaft design. On the two sets of transmission shafts driven by the meshing crushing transmission gears, there are multiple sets of crushing blades with opposite and staggered cutting edges, forming a highly efficient shearing and extrusion action. The internal baffle can scrape off the material adhering to the crushing blades, ensuring a long-lasting and stable crushing effect, thereby making the output particle size more uniform.

[0019] (5) It has self-cleaning capabilities and is easy to maintain. After the work is completed, the flushing pipe can simultaneously flush the conveyor belt and the inclined bottom surface of the recycling device shell, and the sewage is discharged through the drain outlet. Combined with the cleaning of the belt by the discharge scraper, the internal cleaning of the equipment is realized, which reduces the amount of maintenance work and extends the service life of the equipment.

[0030] In a specific embodiment, the transmission mechanism includes a transmission drive motor 27 fixed on the housing 16 of the recycling device. The output end of the transmission drive motor 27 is sequentially connected to a first sprocket 28 and a first pulley 31. The first sprocket 28 is engaged with a second sprocket 30 via a chain 29.

The housing 16 of the recycling device also has a flushing pipe 36 facing the conveyor belt 33 and a discharge scraper 34 that is inclined and whose end is in contact with the conveyor belt 33.

[0031] In a specific embodiment, the water mist nozzles of the spray pipe 35 are symmetrically distributed on both sides of the discharge port 26; the flushing pipe 36 is provided with two sets of water flow nozzles, one set facing the conveyor belt 33 and the other set facing the bottom surface of the recycling device housing 16.

[0032] In a specific embodiment, one end of the outer shell 16 of the recycling device is provided with a drain outlet 38, and the bottom of the outer shell 16 of the recycling device is an inclined surface that slopes toward the drain outlet 38.

[0033] In a specific embodiment, the inclination angle of the sieve plate 12 is 30°.

[0034] The working principle is as follows: When the operator needs to process construction solid waste, the crushing drive motor 8 is started, driving the transmission shaft 37 and the crushing transmission gear 9 to rotate several symmetrically distributed crushing blades 10. Then, by controlling the first electric telescopic rod 3, the top of the feeding shell 1 is opened, allowing large pieces of solid waste to be added into the crushing device. Through the interaction between the crushing blades 10, the construction waste is squeezed and crushed, falling downwards into the screening device. Several sets of baffles 7 scrape both sides of the crushing blades 10 to prevent the crushed waste from sticking to the surface of the crushing blades 10, thus affecting their service life. By controlling four sets of vibration motors 15 to move up and down synchronously, the screening plate 12 vibrates up and down with the assistance of auxiliary blocks 13 and buffer springs 14. Large pieces of material and powder are separated from the surface by the vibration of the screen plate 12. The large pieces of material slide down from the distribution port 25 through the inclined surface of the screen plate 12 into the transfer mechanism housing 18. After the transfer mechanism housing 18 is fully loaded, the entire transfer mechanism is moved upward along the track on the surface of the crushing device housing 6, the screen device housing 11, and the recycling device housing 16 by the second electric telescopic rod 17. When the transfer mechanism moves upward, the distribution port 25 is blocked by the guide baffle 23 to prevent large pieces of material from sliding out of the screen device housing 11. When the transfer mechanism moves upward to the cover plate 5, the cover plate 5 is squeezed open by the rotation of the torsion spring 4, opening the opening on one side of the screen device housing 11. When one side of the transfer mechanism housing 18 is fully inserted into this opening, the second electric telescopic rod 17 is used to move the entire transfer mechanism upward along the track on the surface of the crushing device housing 6, the screen device housing 11, and the recycling device housing 16. The three electric telescopic rods 20 drive the pusher plate 21 to push the large pieces of material in the transfer mechanism housing 18 back into the crushing device, thereby achieving the purpose of further crushing. When the transfer mechanism moves downward, the cover plate 5 closes the opening on the feed housing 1 through the torsion spring 4 to restore its deformation. Through the above operations, the construction waste can be crushed more finely, avoiding large pieces of material from clogging the screen plate 12, so that it reaches the required particle size for recycling, reducing the waste volume, reducing transportation costs, and improving the recycling rate. The powdery waste that is screened falls into the recycling device housing 16 through the discharge port 26. The spray pipe 35 is opened to spray water mist to reduce dust inside the recycling device housing 16. At the same time, the surface of the conveyor belt 33 is wetted to increase the powder adsorption capacity. The transmission drive motor 27 drives the conveyor belt 33 to move towards the discharge scraper 34, scraping the dust adsorbed on the surface of the conveyor belt 33 off and discharging it for collection. After the crushing operation is completed, the operator can control the flushing pipe 36 to spray water to wash off the residue that was not scraped off the surface of the conveyor belt 33. At the same time, another set of water spray pipes will be used to wash off the residue at the bottom of the recycling device housing 16. The residue will be discharged from the drain outlet 38 with the inclined bottom surface. All of the above greatly reduces the dust phenomenon during the crushing and recycling of solid waste, thereby reducing the occupational disease risk of the operator's working environment. At the same time, the automated crushing and recycling process also greatly reduces the labor intensity of the operator and improves the treatment efficiency of construction solid waste.
