Description

Technical Field

[0001] This invention relates to the technical field of waste treatment, and specifically to a construction waste treatment device. Background Technology

[0002] Construction waste processing equipment transforms construction waste into reusable resources such as recycled aggregates, metals, and wood through processes such as crushing and screening. This helps reduce environmental pollution and promotes resource recycling. However, the screen holes of existing construction waste processing equipment are easily clogged by waste, resulting in reduced screening efficiency. In addition, since some construction waste may be damp, the guide plate at the front of the screen cylinder, which is used to guide the construction waste in the screen cylinder, can easily cause waste particles to adhere to its surface and accumulate during the guiding process, making it inconvenient to discharge the waste. Summary of the Invention

[0003] The purpose of this invention is to provide a construction waste treatment device to overcome the above-mentioned defects in the prior art.

[0004] A construction waste treatment device includes a frame, a crushing mechanism, a screening mechanism, and an anti-clogging and cleaning mechanism;

[0005] The crushing mechanism is located in the crushing box on one side of the frame and is used to crush construction waste.

[0006] The screening mechanism is mounted on the frame and is used to screen the crushed construction waste.

[0007] The anti-clogging and cleaning mechanism is located on the frame and outside the screen cylinder of the screening mechanism, and is used to clean the screen cylinder and the guide plate on the frame.

[0008] Preferably, the crushing mechanism further includes crushing rollers, gears, and a right-angle motor. The bottom of the crushing box is provided with a discharge hopper that extends into the screen cylinder. Two crushing rollers are provided and symmetrically rotated and connected in the crushing box. Each crushing roller is provided with a gear, and the two gears mesh with each other. The right-angle motor is installed on the outside of the crushing box and its output shaft is connected to one of the crushing rollers.

[0009] Preferably, the screening mechanism further includes a right-angle motor II, a rotating shaft, a sprocket I and a sprocket II. The front and rear sides of the frame are respectively provided with rollers that are rotatably connected to two guide rails on the screen cylinder. The output shaft of the right-angle motor II is connected to the rotating shaft rotatably connected to the frame. The sprocket I on the rotating shaft is connected to the sprocket II on the screen cylinder through a chain.

[0010] Preferably, the anti-clogging cleaning mechanism includes a movable plate, a brush plate, a sector gear, and an elastic scraper. The movable plate is slidably connected to the frame via a slide rod. A spring is fitted on the slide rod between a baffle plate at the end of the frame and the slide rod. The end of the L-shaped rod on the movable plate is inserted into the drive groove of the fixed ring on the screen cylinder. The brush plate is provided with several steel wire bristles. Both ends of the brush plate are slidably connected to guide rods on the movable plate. A spring is fitted on the guide rod between a baffle plate at the end of the movable plate and the guide rod. The screen cylinder is provided with a drive plate that abuts against the brush plate. The sector gear is rotatably connected to a support plate on the front side of the frame. The sector gear meshes with a rack on the movable plate. The sector gear is connected to an elastic scraper located in the guide plate via a fixed plate.

[0011] Preferably, the drive board has a peak-valley structure.

[0012] Preferably, the drive slot has several triangular top blocks evenly distributed in it.

[0013] Preferably, there are several slide bars.

[0014] The beneficial effects achieved by this invention are as follows:

[0015] This application uses a crushing roller in a crushing mechanism to crush construction waste, and then uses a screening mechanism to screen the crushed construction waste through a screen cylinder. During screening, the top block in the drive groove of the fixed ring drives the moving plate to reciprocate on the screen cylinder, brushing the screen cylinder and causing the waste stuck in the screen holes to fall off. The fixed plate on the sector gear drives the elastic scraper to reciprocate on the guide plate. Because the elastic scraper can deform, it can always contact the surface of the guide plate during movement, making it easier to clean the construction waste attached to the guide plate. At the same time, the peak-valley drive plate drives the brush plate to reciprocate and vibrate, keeping the steel wire bristles on the brush plate clean and better cleaning the screen cylinder.

[0023] like Figure 1-5 As shown, the present invention provides a construction waste treatment device, including a frame 1, a crushing mechanism 2, a screening mechanism 3 and an anti-clogging and cleaning mechanism 4;

[0024] It should be noted that the crushing mechanism 2 is located in the crushing box 21 on one side of the frame 1 and is used to crush construction waste. The crushing mechanism 2 also includes crushing rollers 22, gears 23 and right-angle motor 24. The bottom of the crushing box 21 is provided with a discharge hopper 211 that extends into the screen cylinder 31. There are two crushing rollers 22 that are symmetrically rotatably connected in the crushing box 21. Each crushing roller 22 is provided with a gear 23, and the two gears 23 mesh with each other. The right-angle motor 24 is installed on the outside of the crushing box 21 and its output shaft is connected to one of the crushing rollers 22.

[0025] In addition, the screening mechanism 3 is mounted on the frame 1 and is used to screen the crushed construction waste. The screening mechanism 3 also includes a right-angle motor 34, a rotating shaft 35, a first sprocket 36 and a second sprocket 38. The front and rear sides of the frame 1 are respectively provided with rollers 33 that are tactilely connected to two guide rails 32 on the screen cylinder 31. The output shaft of the right-angle motor 34 is connected to the rotating shaft 35 rotatably connected to the frame 1. The first sprocket 36 on the rotating shaft 35 is connected to the second sprocket 38 on the screen cylinder 31 through a chain 37.

[0026] Additionally, the anti-clogging cleaning mechanism 4 is mounted on the frame 1 and located outside the screen cylinder 31 of the screening mechanism 3, and is used to clean the screen cylinder 31 and the guide plate 11 on the frame 1. The anti-clogging cleaning mechanism 4 includes a moving plate 41, a brush plate 44, a sector gear 46, and an elastic scraper 49. The moving plate 41 is slidably connected to the frame 1 via a slide rod 411. A spring 413 is sleeved on the slide rod 411 between the frame 1 and the baffle 412 at the end of the slide rod 411. Several slide rods 411 are provided. The end of the L-shaped rod 42 on the moving plate 41 is inserted into the drive groove 431 of the fixing ring 43 on the screen cylinder 31. Several triangular... The top block 432 has a shaped structure. The brush plate 44 is provided with several steel wire bristles 441. The two ends of the brush plate 44 are slidably connected to the guide rods 442 on the moving plate 41. The guide rods 442 are fitted with springs 444 located between the baffles 443 at the ends of the moving plate 41 and the guide rods 442. The screen cylinder 31 is provided with a drive plate 45 that abuts against the brush plate 44. The drive plate 45 has a peak-valley structure. The sector gear 46 is rotatably connected to the support plate 461 on the front side of the frame 1. The sector gear 46 meshes with the rack 47 on the moving plate 41. The sector gear is connected to the elastic scraper 49 located in the guide plate 11 through the fixing plate 48.

[0027] Detailed implementation methods and principles:

[0028] During operation, right-angle motor 24 and right-angle motor 34 are turned on. The output shaft of right-angle motor 24 drives one of the crushing rollers 22 to rotate, and then drives the other crushing roller 22 to rotate through the gear 23 on it, so that the construction waste poured into the crushing box 21 is crushed. After crushing, it enters the screen cylinder 31 through the discharge hopper 211. The output shaft of right-angle motor 34 drives the sprocket 36 on the rotating shaft 35 to rotate. The sprocket 36 drives the sprocket 38 and the screen cylinder 31 to rotate through the chain 37, so as to screen the construction waste in the screen cylinder 31. At the same time, the drive plate 45 on the screen cylinder 31 lifts the brush plate 44 through its peak. When the peak of the drive plate 45 is separated from the brush plate 44, under the elastic force of the spring 444 on the guide rod 442, the steel wire bristles 441 on the brush plate 44 contact the screen cylinder 31. When the fixed ring 43 drives the brush plate 44, the brush plate 44 is in contact with the screen cylinder 31. When the top block 432 on one side of the moving groove 431 contacts the L-shaped rod 42, it squeezes the L-shaped rod 42. At this time, the spring 413 on the slide rod 411 is compressed, the moving plate 41 moves, and the brush plate 44 drives the steel wire bristles 441 on it to brush. The rack 47 on the inner side of the moving plate 41 drives the sector gear 46 to rotate. The elastic scraper 49 on the fixed plate 48 scrapes the attached material on the guide plate 11. When the L-shaped rod 42 contacts the other side of the top block 432, the moving plate 41 drives the brush plate 44 to reset under the elastic force of the spring 413. The reciprocating brushing of the screen cylinder 31 by the steel wire bristles 441 causes the waste stuck on the screen cylinder 31 to fall off. Then, the peak on the drive plate 45 lifts the brush plate 44 again, causing the steel wire bristles 441 on the brush plate 44 to vibrate. The attached material on the steel wire bristles 441 is shaken off, keeping it clean.

[0029] In summary, this application uses the crushing roller 22 of the crushing mechanism 2 to crush construction waste, and then uses the screen cylinder 31 of the screening mechanism 3 to screen the crushed construction waste. During screening, the top block 432 in the drive groove 431 of the fixed ring 43 drives the moving plate 41 to reciprocate on the screen cylinder 31, brushing the screen cylinder 31 and causing the waste stuck in its screen holes to fall off. The fixed plate 48 on the sector gear 46 drives the elastic scraper 49 to reciprocate on the guide plate 11. Since the elastic scraper 49 can deform, it can always contact the surface of the guide plate 11 during the movement, making it easier to clean the construction waste attached to the guide plate 11. At the same time, the peak-valley drive plate 45 drives the brush plate 44 to reciprocate and vibrate, keeping the steel wire bristles 441 on the brush plate 44 clean and better cleaning the screen cylinder 31.
