Description

Technical Field

[0001] The present invention belongs to the technical field of construction waste recycling, and in particular relates to a highly efficient and environmentally friendly construction waste treatment and recycling device. Background Art

[0002] During construction and demolition, wood-based construction waste (such as plywood and formwork) accounts for 10%-15% of waste. Its high recycling value allows it to be used as biomass fuel and raw materials for artificial board materials after crushing, thus meeting the requirements of a circular economy. However, traditional disposal methods have significant drawbacks: landfilling can pollute soil and groundwater, while incineration produces pollutants such as dust and formaldehyde. Existing crushing equipment is also insufficiently capable of handling wood containing impurities, resulting in uneven particle size after crushing, making it difficult to meet the demand for high-quality recycling.

[0029] The material conveying pipe 330 of this embodiment is arranged at an angle, and the bottom plate of the material conveying pipe 330 is tangent to the bottom of the second arc segment 244 .

[0030] In this embodiment, a maintenance port is provided at the front end of the crushing box 240 , and a sealing plate is provided on the maintenance port. The sealing plate is connected to the crushing box 240 by bolts.

[0031] Working Principle: This highly efficient and environmentally friendly construction waste processing and recycling equipment primarily crushes construction waste through a processing device 200, and then recycles the crushed waste through a recycling device 300. Specifically, the processing box 210 is used for placing and preliminarily processing waste. The flap 220 can be opened to facilitate waste placement. Its inclined opening 211 and transparent PVC cover facilitate operation and observation. The V-shaped structure and raised ridges 213 at the bottom of the processing box 210 allow the waste to be concentrated and preliminarily processed before entering the crushing box 240 through a hopper 230. The crushing rollers 250 within the crushing box 240, driven by a crushing motor 260, crush the waste. The different arc segments of the crushing rollers 250 and auxiliary ridges 245 achieve phased and differentiated crushing, improving the crushing effect. The recovery fan 310 of the recovery device 300, under the action of the drive motor 340, sucks the garbage in the crushing box 240 through the conveying pipe 330 and discharges it for recovery through the discharge pipe 320, using the suction force of the fan to realize the transportation and recovery of the garbage.

[0032] Working process: 1. Garbage delivery: The operator holds the handle at the lower end of the outer frame of the flip cover 220, opens the flip cover 220, and drops the construction waste into the treatment box 210 through the inclined opening 211 at the upper end of the treatment box 210. The transparent PVC cover allows the operator to clearly observe the delivery process. After delivery is completed, close the flip cover 220 and press it on the opening 211 to ensure that the treatment box 210 is closed. 2. Preliminary treatment: The bottom of the treatment box 210 is a V-shaped structure. Under the action of gravity, the input garbage is concentrated towards the long strip opening 212 at the bottom. The ridge 213 on the inner wall located just above the long strip opening 212 can exert a certain squeezing and friction effect on the garbage, achieving preliminary crushing or separation, removing some impurities or reducing the size of garbage lumps to facilitate subsequent treatment. 3. Crushing: After preliminary processing, the garbage enters the hopper 230 through the elongated opening 212 and then enters the crushing chamber 240 from the bottom of the hopper 230. The crushing chamber 240 is connected from top to bottom by a straight section 242, a first curved section 243, and a second curved section 244. The garbage first enters the straight section 242 and then reaches the first curved section 243. The crushing teeth 251 on the two crushing rollers 250 in the first curved section 243 are staggered. Driven by the crushing motor 260, the two crushing rollers 250 rotate in opposite directions, performing the initial crushing of the garbage, breaking larger garbage chunks into smaller particles. The crushed particles then enter the second curved section 244. The crushing rollers 250 in the second curved section 244 are equipped with sharp teeth 252. These teeth are also interlaced with auxiliary ridges 245, which extend along the direction of rotation of the crushing rollers 250 to the opening 241 in the second curved section 244. The sharp teeth 252 can crush the particles more finely, and the auxiliary edges 245 assist the sharp teeth 252 to further crush and transport the particles, making the crushed materials smaller and moving toward the opening 241 along the rotation direction of the auxiliary edges 245 and the crushing roller 250. 4. Recycling: The rear sidewall of the crushing chamber 240 is provided with an opening 241. The feed pipe 330 of the recovery device 300 is connected to this opening 241. The feed pipe 330 is tilted, with its bottom plate tangent to the bottom of the second arc segment 244, facilitating the smooth entry of crushed material into the feed pipe 330. The drive motor 340 rotates the impeller within the recovery fan 310, generating suction at the feed inlet of the recovery fan 310. This draws material from the feed pipe 330 into the recovery fan 310. After processing by the fan, the material is discharged through the discharge pipe 320, thus recycling construction waste. When maintenance is required, the cover plate (bolted to the crushing chamber 240) can be opened through the maintenance port at the front of the crushing chamber 240 to inspect and replace components within the crushing chamber 240.

[0033] Advantages display: 1. Efficient crushing: The crushing box 240 adopts a structure of a straight section 242, a first arc section 243 and a second arc section 244. The crushing roller 250 with two flat teeth 251 and two interlaced crushing teeth in the first arc section 243 can perform primary crushing of the garbage, increase the crushing contact area, and improve crushing efficiency; the sharp teeth 252 in the second arc section 244 of the crushing roller 250 and the auxiliary ridges 245 can perform secondary fine crushing of the material. The auxiliary ridges 245 can also assist in conveying the material, making the crushing process more efficient and the particle size of the crushed material more uniform, meeting recycling requirements. 2. Environmental protection and energy saving: The entire equipment realizes the treatment and recycling of construction waste, reduces the amount of landfill waste, and reduces pollution to the environment; the recovery device 300 uses the suction force of the fan to transport materials. Compared with traditional mechanical transportation methods, it has lower energy consumption, and the equipment is better sealed during operation, reducing the emission of pollutants such as dust, which meets environmental protection requirements. 3. Convenient Operation: The design of the flip cover 220 facilitates the placement of garbage. The handle formed by the bend at the lower end of the outer frame allows the operator to open and close the flip cover 220 easily. The transparent PVC cover allows the operator to observe the placement and treatment of garbage in the treatment box 210 at any time. The V-shaped structure and ridge 213 design at the bottom of the treatment box 210 automatically collect garbage at the long opening 212 for preliminary treatment, reducing manual intervention and improving the convenience of operation. 4. Easy maintenance: A maintenance port is provided at the front end of the crushing box 240, and the sealing plate is connected by bolts, which makes it easy for operators to maintain and replace components such as the crushing roller 250 and auxiliary ribs 245 inside the crushing box 240, thereby reducing the maintenance cost and downtime of the equipment and improving the reliability and service life of the equipment. 5. Reasonable structure: The conveying pipe 330 is set at an angle and the bottom plate is tangent to the bottom of the second arc segment 244. This design conforms to the flow characteristics of the material, ensuring that the crushed material can smoothly enter the conveying pipe 330, avoiding blockage and ensuring the continuous and stable operation of the equipment; the connection between the various components is compact and the layout is reasonable. The overall structure of the equipment is stable and occupies little space, making it easy to move and use on construction sites. The setting of the traction frame 100 also improves the maneuverability of the equipment.
