Description

Construction waste recycling device

Technical Field

The invention relates to the technical field of construction waste recycling, in particular to a construction waste recycling device.

Background Art

Construction waste refers to the general term for slag, waste concrete, waste bricks and stones and other wastes generated by people in the production activities of the construction industry such as demolition, construction, decoration and repair. According to the source of generation, construction waste can be divided into engineering slag, decoration waste, demolition waste, engineering mud, etc.; according to the composition, construction waste can be divided into slag, concrete blocks, broken stones, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste metals, waste bamboo and wood, etc.

Existing construction waste recycling equipment uses a double-shaft shredder for preliminary crushing. The double-shaft shredder uses a serrated cutter. Since the number of teeth of the serrated cutter is fixed, when encountering large construction waste, the contact area between the cutter and the material is limited, making it impossible to efficiently crush the material.

Existing construction waste recycling equipment uses hydraulic flotation to screen the light garbage of construction waste, but still needs to be transported away manually, which consumes manpower and material resources and increases the cost of recycling.

Summary of the invention

The object of the present invention is to provide a construction waste recycling device to solve the problems raised in the prior art.

To achieve the above object, the present invention provides the following technical solutions:

A construction waste recycling device, the recycling device includes a support base, a No. 1 support frame, a No. 1 crushing mechanism, a screening mechanism, a No. 2 support frame, a magnetic separation mechanism, a No. 3 support frame and a No. 2 crushing mechanism, the support base is fixedly connected to the No. 1 support frame, the No. 1 crushing mechanism is fixedly connected to the No. 1 support frame, the screening mechanism is fixedly connected to the No. 1 support frame, the No. 2 support frame is fixedly connected to the support base, the magnetic separation mechanism is fixedly connected to the screening mechanism, and the No. 3 support frame is fixedly connected to the No. 2 crushing mechanism.

This recycling device uses the No. 1 crushing mechanism to initially crush the construction waste. The crushed materials fall into the screening mechanism placed under the No. 1 crushing mechanism, which screens out lightweight materials that can float on the water surface, such as plastics and wood. The remaining construction waste is further screened out of the metal through the magnetic separation mechanism, and finally the No. 2 crushing mechanism further crushes the remaining construction waste into recycled aggregate.

Furthermore, the No. 1 crushing mechanism includes a shell, a No. 1 machine base, a No. 1 motor, a No. 1 gear, a rotating shaft and a serrated cutter. The shell is fixedly connected to the No. 1 support frame, the shell is provided with a feed port, the No. 1 machine base is fixedly connected to the No. 1 support frame, the No. 1 motor is fixedly connected to the No. 1 machine base, the No. 1 motor is fixedly connected to the No. 1 machine base, the No. 1 motor output end is fixedly connected to the rotating shaft, the shell is provided with a working chamber, two rotating shafts are provided, the rotating shaft is placed in the working chamber, the rotating shaft is rotatably connected to the working chamber, the No. 1 gear is transmission-connected to the rotating shaft, a number of serrated cutters are provided, the serrated cutters are transmission-connected to the rotating shaft, and the shell is provided with a discharge port.

Construction waste enters through the feed port and falls into the working chamber. The rotating shaft is driven by motor No. 1 to rotate, so that the rotating shaft drives the sawtooth cutter to rotate. The sawtooth cutters are distributed on two rotating shafts and arranged in a staggered manner, so that the rotating sawtooth cutters shear and squeeze the construction waste falling into the working chamber. The construction waste is subjected to forces in different directions from the sawtooth cutters, thereby breaking it into small pieces of construction waste and discharging it through the discharge port.

Furthermore, the serrated tool includes a cutter disc, a movable blade, a fixed blade, a No. 1 spring, a limit block, a No. 2 spring and a slider.

The movable blade is fixedly connected to a spring No. 1 on the sliding groove. When construction waste greater than the gap between the movable blade and the fixed blade on the two shafts falls, the construction waste will fall onto the back of the movable blade. Due to the action of gravity, the No. 1 spring is compressed, and the movable blade slides down in the sliding groove, so that the number of teeth of the serrated tool is reduced compared with the initial state, thereby increasing the blade gap of the serrated tool, increasing the contact area between the construction waste and the serrated tool, and increasing the efficiency of construction waste crushing. When the waste is crushed to be smaller than the blade gap, the kinetic energy is released through the No. 1 spring, causing the movable blade to rise, thereby reducing the blade gap and the waste being crushed into smaller pieces. When the falling waste is smaller than the blade gap, it is crushed normally.

After preliminary crushing, the construction waste falls into the water tank through the discharge port. Due to the buoyancy of water, lightweight construction waste such as plastic and wood floats on the water surface. Water is pumped by a water pump and flows into the water tank through a water pipe. The water in the water tank flows out from the No. 1 water outlet. The construction waste floating on the water surface flows out from the No. 1 water outlet with the water flow and falls into the No. 2 conveying unit. The water flows into the recycling box through the No. 2 conveying unit for recycling. The lightweight construction waste falls into the collection box, and the construction waste that does not float on the water surface falls onto the No. 1 conveying unit and moves to the magnetic separation mechanism with the No. 1 conveying unit.

The water baffle is fixedly connected to the No. 2 conveyor belt. The water baffle is slidably connected to the material guide pipe. The material guide pipe is provided with a No. 2 water outlet, and the No. 2 water outlet faces the recycling box.

Lightweight construction waste flows from the No. 1 water outlet to the No. 2 conveyor belt of the guide pipe with the water flow. The gravitational potential energy of the water is converted into power, which passes through the water baffle on the No. 2 conveyor belt. The power generated pushes the water baffle, causing the No. 2 conveyor belt mounted on the No. 2 roller to rotate. The lightweight construction waste moves with the No. 2 conveyor belt and finally falls into the collection box. After the water moves a certain distance on the No. 2 conveyor belt through the guide plate, it flows out from the filter holes set on the No. 2 conveyor belt and flows to the recovery box through the No. 2 water outlet, so that the water can be recycled.

Furthermore, the magnetic separation mechanism includes an outer shell, a fixed frame, a No. 3 motor, a No. 2 gear, a No. 3 transmission unit, a power belt, a clamping block, a guide plate and a collecting box.

The screened construction waste moves with the No. 1 conveyor belt and falls into the No. 3 conveyor unit. The No. 3 motor drives the top No. 3 conveyor unit to rotate. Through the No. 2 gear, the top No. 3 conveyor unit drives the middle No. 3 conveyor unit to rotate. Through the power belt, the top No. 3 conveyor unit drives the bottom No. 3 conveyor unit to rotate. Through the block, the metal adsorbed on the No. 3 conveyor unit falls onto the guide plate. Under the action of gravity, the metal falls into the collection box along with the guide plate.

The No. 3 motor drives the No. 3 roller to rotate, and the No. 3 roller drives the No. 3 conveyor belt to rotate. The construction waste moves with the No. 3 conveyor belt. The support block allows the No. 3 conveyor belt to work smoothly, reducing the impact force when the construction waste falls, and extending the service life of the No. 3 conveyor belt. The magnet plate on the No. 3 conveyor belt allows the metal in the construction waste to be adsorbed on the magnet plate, and the remaining construction waste is conveyed away with the No. 3 conveyor belt. The upper and lower No. 3 conveyor belts are both equipped with magnet plates, so that the missed scrap metal is magnetically separated for the second time, thereby improving the recovery rate of scrap metal.

The construction waste falls into the feed pipe, slides through the feed pipe, and lands on the plate hammer. The No. 4 motor drives the transmission shaft to rotate, causing the plate hammer to rotate, thereby hitting the falling waste against the impact rack. Due to the strong impact force generated by the plate hammer hitting the construction waste, the construction waste is broken into smaller particles by the reaction force on the impact rack.

Compared with the prior art, the present invention has the following beneficial effects:

1. By setting a sliding groove, a No. 1 spring is set in the sliding groove, and the No. 1 spring is fixedly connected to the movable blade. When construction waste that is larger than the gap between the movable blade and the fixed blade on the two axes falls, the construction waste will fall on the back of the movable blade. Due to the effect of gravity, the No. 1 spring is compressed, and the movable blade slides down in the sliding groove, so that the number of teeth of the serrated tool is reduced compared with the initial state, thereby increasing the blade gap of the serrated tool, increasing the contact area between the construction waste and the serrated tool, and increasing the efficiency of construction waste crushing.

2. After the initial crushing, the construction waste falls into the water tank through the discharge port. Due to the buoyancy of water, lightweight construction waste such as plastic and wood floats on the water surface. Water is pumped by a water pump and flows into the water tank through a water pipe. The water in the water tank flows out from the water outlet. The construction waste floating on the water surface falls onto the No. 2 conveyor belt with the water flow. The gravitational potential energy of the water is converted into power. The power generated pushes the water baffle plate on the No. 2 conveyor belt, so that the No. 2 conveyor belt mounted on the No. 2 roller rotates. The lightweight construction waste moves with the No. 2 conveyor belt and finally falls into the collection box. After the water moves a certain distance on the No. 2 conveyor belt through the guide plate, it flows out from the filter holes set on the No. 2 conveyor belt and flows into the recycling box through the No. 2 water outlet, so that the water is recycled, which reduces human intervention. The lightweight construction waste is driven by water to move, which reduces dependence on electricity and saves the cost of recycling.

3. The support block enables the No. 3 conveyor belt to work smoothly, reducing the impact force when the construction waste falls, extending the service life of the No. 3 conveyor belt, and the metal in the construction waste can be adsorbed on the magnet plate on the No. 3 conveyor belt. The remaining construction waste is conveyed away with the No. 3 conveyor belt. The upper and lower No. 3 conveyor belts are equipped with magnet plates, so that the missed scrap metal is magnetically separated for the second time, thereby improving the recovery rate of scrap metal.

Construction waste enters through the feed port 311 and falls into the working chamber 313. The rotating shaft 35 is driven to rotate by the No. 1 motor 33, so that the rotating shaft 35 drives the serrated cutter 36 to rotate. By distributing the serrated cutters 36 on the two rotating shafts 35 and arranging them in a staggered manner, the rotating serrated cutters 36 shear and squeeze the construction waste falling into the working chamber 313. The construction waste is subjected to forces in different directions from the serrated cutters 36, thereby breaking into small pieces of construction waste and being discharged through the discharge port 312.

The screened construction waste moves along the No. 1 conveyor belt 424 and falls into the No. 3 conveyor unit 65. The No. 3 motor 63 drives the top No. 3 conveyor unit 65 to rotate. Through the No. 2 gear 64, the top No. 3 conveyor unit 65 drives the middle No. 3 conveyor unit 65 to rotate. Through the power belt 66, the top No. 3 conveyor unit 65 drives the bottom No. 3 conveyor unit 65 to rotate. Through the block 67, the metal adsorbed on the No. 3 conveyor unit 65 falls onto the guide plate 68. Under the action of gravity, the metal falls into the collection box 69 along with the guide plate 68.

As shown in Figures 3, 10 and 11, the No. 3 conveying unit 65 includes a No. 3 roller 651, a support block 652, a No. 3 conveyor belt 653 and a magnet plate 654. The No. 3 roller 651 is transmission-connected to the outer shell 61, the support block 652 is fixedly connected to the outer shell 61, the No. 3 conveyor belt 653 is sleeved on the outer rings of the two No. 3 rollers 651, and the magnet plate 654 is sleeved on the upper and lower outer rings of the No. 3 conveyor belt 653.

The No. 3 motor 63 drives the No. 3 roller 651 to rotate, and the No. 3 roller 651 drives the No. 3 conveyor belt 653 to rotate, and the construction waste moves with the No. 3 conveyor belt 653. The support block 652 allows the No. 3 conveyor belt 653 to work smoothly, reducing the impact force when the construction waste falls, and extending the service life of the No. 3 conveyor belt 653. The magnet plate 654 on the No. 3 conveyor belt 653 allows the metal in the construction waste to be adsorbed on the magnet plate 654, and the remaining construction waste is conveyed away with the No. 3 conveyor belt 653. The upper and lower No. 3 conveyor belts 653 are both provided with magnet plates 654, so that the missed scrap metal is magnetically separated for a second time, thereby improving the recovery rate of the scrap metal.

As shown in Figures 1 and 3, the No. 2 crushing mechanism 8 includes a box body 81, a No. 3 machine base 82, a No. 4 motor 83, a transmission shaft 84, a plate hammer 85, an impact frame 86 and a feed pipe 87. The box body 81 is fixedly connected to the No. 3 support frame 7, the No. 3 machine base 82 is fixedly connected to the No. 3 support frame 7, the No. 4 motor 83 is fixedly connected to the No. 3 machine base 82, the output end of the No. 4 motor 83 is fixedly connected to the transmission shaft 84, the transmission shaft 84 is fixedly connected to the plate hammer 85, the transmission shaft 84 is transmission-connected to the box body 81, the plate hammer 85 is slidably connected to the box body 81, the impact frame 86 is fixedly connected to the box body 81, and the feed pipe 87 is fixedly connected to the box body 81.

The construction waste falls into the feed pipe 87, slides through the feed pipe 87, and falls onto the plate hammer 85. The transmission shaft 84 is driven to rotate by the No. 4 motor 83, so that the plate hammer 85 rotates, thereby knocking the falling waste onto the impact frame 86. Since the plate hammer 85 collides with the construction waste and generates a strong impact force, the construction waste is crushed into smaller particles by the reaction force on the impact frame 86.

Working principle: Construction waste enters the processing system through the feed port 311, and the No. 1 motor 33 drives the rotating shaft 35 to drive the serrated cutter 36 to rotate, shearing and squeezing the waste. When the waste larger than the blade gap falls, it will fall on the back of the movable blade 362. Due to the gravity, the No. 1 spring 364 is compressed, and the movable blade 362 slides down, increasing the blade gap, thereby increasing the contact area of the waste and improving the crushing efficiency. When the waste is crushed to be smaller than the blade gap, the kinetic energy is released by the No. 1 spring 364, causing the movable blade 362 to rise, thereby reducing the blade gap and the waste is crushed into smaller pieces. When the falling waste is smaller than the blade gap, it is crushed normally. The crushed waste is discharged through the discharge port 312 and falls into the water tank 41. Light waste such as plastic and wood floats on the water surface and is driven by the water flow pumped into the water tank 41 by the water pump 47. It falls to the No. 2 conveyor belt 434 through the guide pipe 431 and finally falls into the collection box 45. The water flows out from the filter holes on the No. 2 conveyor belt 434 for recycling. The waste that does not float on the water surface falls onto the No. 1 conveying unit 42 and moves to the magnetic separation mechanism 6. The No. 3 motor 63 drives the No. 3 roller 651 to rotate, driving the No. 3 conveyor belt 653 to move the waste. The magnet plate 654 on the conveyor belt absorbs the metal in the waste, and the remaining waste is conveyed away. The upper and lower No. 3 conveyor belts 653 are both provided with magnet plates 654 to improve the recovery rate of waste metal. Finally, the waste falls into the feed pipe 87 and slides onto the plate hammer 85. The No. 4 motor 83 drives the transmission shaft 84 to rotate, causing the plate hammer 85 to rotate and hit the waste against the impact frame 86, generating a strong impact force, so that the waste is crushed into smaller particles by the reaction force on the impact frame 86.
