Description

Technical Field

[0001] This utility model relates to the field of construction waste crushing technology, and in particular to a construction waste crushing device. Background Technology

[0002] When processing construction waste, large pieces of waste need to be crushed first. Chinese patent CN217747210U discloses a construction waste crushing device, including a crusher body and an auxiliary installation module. The auxiliary installation module includes an installation cover, an inner box, a pressing plate, and a movable chamber. The installation cover is directly installed on the top of the crusher body and is hollow and annular. The inner box is located on the inner wall of the installation cover, and a movable chamber is located on the side of the inner box near the axis of the installation cover. The pressing plate is located in the movable chamber. It presses the waste downwards, reducing the bouncing phenomenon of the waste during the crushing process and promoting the crushing efficiency. At the same time, when a large amount of waste enters the working chamber, it can provide upward support for the waste through elastic enclosure.

[0003] Because construction waste is diverse and often contains unpleasant odors, these odors are released during crushing. The aforementioned patents lack the ability to treat these odors, leading to air pollution. Furthermore, they cannot compress the crushed construction waste to reduce its volume, hindering subsequent storage and transportation. Therefore, there is an urgent need to develop a construction waste crushing device that facilitates crushing, absorbs odors generated during crushing to reduce air pollution, and compresses the crushed waste to reduce its volume for easier processing. This would overcome the shortcomings of current applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a construction waste crushing device to solve the problems mentioned in the background art.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A construction waste crushing device includes a crushing box, a baffle, a receiving box, a crushing mechanism, an odor treatment mechanism, and a volume compression mechanism. The baffle is fixedly installed above the crushing box. The crushing mechanism is installed inside the crushing box. The receiving box is placed on the ground below the crushing box, and the volume compression mechanism is installed on the receiving box. The odor treatment mechanism is connected inside the baffle. The odor treatment mechanism includes an exhaust fan, a duct, an air inlet, an air supply pipe, an adsorption box, and an exhaust pipe. The exhaust fan and the adsorption box are both placed on the ground. The duct is fixed inside the baffle and has multiple air inlets installed on it. The bottom end of the duct is connected to the intake end of the exhaust fan. The exhaust end of the exhaust fan is connected to the adsorption box via the air supply pipe. The adsorption box is filled with activated carbon, and an exhaust pipe is installed on one side of the adsorption box.

[0007] Preferably, the top of the adsorption box is detachably fitted with a top cover.

[0008] Preferably, the crushing box has a feed inlet at the top and a discharge outlet at the bottom.

[0009] Preferably, the crushing mechanism is located in the middle of the inside of the crushing box.

[0010] Preferably, the crushing mechanism includes: a crushing spiked roller, a gear, and a drive motor. Two crushing spiked rollers are rotatably connected inside the crushing box. Each crushing spiked roller is equipped with a gear, and the two gears mesh with each other. The drive motor is fixed to the outside of the crushing box, and the output shaft of the drive motor is fixed to the crushing spiked roller.

[0011] Preferably, the volume compression mechanism includes a hydraulic cylinder and an extrusion plate. Two hydraulic cylinders are fixed to the outside of the receiving box, and the telescopic ends of the hydraulic cylinders extend into the receiving box and are fixed to the extrusion plate.

[0012] The beneficial effects of this utility model are as follows: This construction waste crushing device allows construction waste to be added to a crushing chamber, where it is pulverized by a crushing mechanism. Simultaneously, an exhaust fan draws in odors emitted from the waste through the air inlet. The exhaust fan then transports the odors to an adsorption chamber, where activated carbon adsorbs the odors before the air is discharged through an exhaust pipe. Furthermore, the crushed waste falls into a collection box, where a hydraulic cylinder moves a pressing plate to compress the waste, reducing its volume for easier subsequent processing. In summary, this utility model facilitates the crushing of construction waste, adsorbs odors generated during crushing to reduce air pollution, and compresses the crushed waste to reduce its volume for easier subsequent processing.

The odor treatment mechanism 5 includes: an exhaust fan 501, a duct 502, an air inlet 503, an air delivery pipe 504, an adsorption box 505, and an exhaust pipe 506. The exhaust fan 501 and the adsorption box 505 are both placed on the ground. The duct 502 is fixed inside the baffle 2 and is equipped with: There are multiple air inlets 503. The bottom end of the duct 502 is connected to the air intake end of the exhaust fan 501. The air outlet end of the exhaust fan 501 is connected to the adsorption box 505 through the air supply pipe 504. The adsorption box 505 is filled with activated carbon. The top of the adsorption box 505 is detachably equipped with a top cover 5051. The activated carbon can be replaced by removing the top cover 5051. An exhaust pipe 506 is installed on one side of the adsorption box 505. When in use, construction waste is added to the crushing box 1. The waste is crushed by the crushing mechanism 4. At the same time, the exhaust fan 501 sucks in the odor emitted from the waste. The odor emitted from the waste is sucked away from the air inlets 503. The exhaust fan 501 delivers the odor to the adsorption box 505. The odor is adsorbed by the activated carbon and then the air is discharged from the exhaust pipe 506. In addition, the crushed waste falls into the collection box 3. The waste is compressed by the volume compression mechanism 6 to reduce its volume and facilitate subsequent processing.

[0025] The crushing mechanism 4 includes: crushing spiked rollers 401, gears 402 and drive motor 403. Two crushing spiked rollers 401 are rotatably connected inside the crushing box 1.

The drive motor 403 is fixed to the outside of the crushing box 1, and the output shaft of the drive motor 403 is fixed to the crushing spiked rollers 401. In use, the drive motor 403 drives the two crushing spiked rollers 401 to rotate, and the construction waste is crushed by the two crushing spiked rollers 401.

[0026] The volume compression mechanism 6 includes a hydraulic cylinder 601 and a pressing plate 602. Two hydraulic cylinders 601 are fixed on the outside of the receiving box 3. The telescopic ends of the hydraulic cylinders 601 extend into the receiving box 3 and are fixed to the pressing plate 602. In use, the hydraulic cylinders 601 drive the pressing plate 602 to move, and the pressing plate 602 compresses the waste in the receiving box 3 to reduce its volume.

[0027] Working principle: This construction waste crushing device feeds construction waste into the crushing box 1, where the crushing mechanism 4 crushes the waste. Simultaneously, the exhaust fan 501 draws in odors from the waste through the air inlet 503. The exhaust fan 501 then transports the odors to the adsorption box 505, where activated carbon adsorbs the odors before the air is discharged through the exhaust pipe 506. Additionally, the crushed waste falls into the receiving box 3, where the hydraulic cylinder 601 moves the extrusion plate 602 to compress the waste in the receiving box 3, reducing its volume for easier subsequent processing.
