Description

Technical Field

[0001] The invention relates to the field of construction waste treatment, and in particular to a civil engineering construction waste treatment device. Background Art

[0002] Civil engineering construction waste refers to various waste materials generated during the construction, demolition, maintenance and reconstruction of buildings, usually including concrete waste, masonry waste, metal waste and wood waste, etc. Concrete waste mainly comes from waste generated during the construction process such as concrete cutting and pouring. When dismantling old buildings, a large amount of concrete blocks and structural materials are generated. In the process of maintenance and reconstruction, old concrete structures are demolished and replaced;

[0003] These concrete wastes are usually crushed and then screened, and then cleaned and converted into recycled aggregates before being put into use. During the crushing process, a large amount of dust will be generated, which will not only affect the health of the operators, but also pollute the surrounding environment. In the prior art, most of them install a spray device at the feed port or discharge port of the crushing equipment through a conveyor belt, and combine the spray water mist particles with the dust particles to reduce the dust concentration in the air. The spray device can be only set at the feed port and the discharge port. For the spray device at the feed port, in the process of adding concrete waste to the hopper through a belt conveyor or a forklift, dust will be generated as the concrete waste is transported from a high place to a low place, and dust will also be generated during the vibration feeding process. The spray device set at the feed port cannot remove the dust generated in the process of adding concrete waste to the hopper through a belt conveyor or a forklift, nor can it remove the dust generated during the vibration feeding process. The dust will be released into the air and pollute the surrounding environment.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] See also Figures 1 to 16 A device for treating construction waste from civil engineering, comprising a treatment box 1, a crushing roller 11 symmetrically rotatably connected to the inner wall of the treatment box 1, a first gear 12 fixedly connected to one end of the crushing roller 11, a second gear meshingly connected to the outer side of the first gear 12 and a first motor fixedly connected to the surface of one of the first gears 12, a water tank 2 fixedly connected to the top of the treatment box 1, a plurality of nozzles 3 fixedly connected to the bottom of the water tank 2, an adjusting mechanism 4 for adjusting the water in the water tank 2 to be sprayed out from the nozzle 3 for dust removal is provided on the inner wall of the water tank 2, a rotating block 5 symmetrically rotatably connected to the surface edge of the treatment box 1, and a feeding mechanism 6 for intermittent feeding of construction waste from civil engineering is provided on the surfaces of the two rotating blocks 5.

[0039] The adjusting mechanism 4 includes a pressure plate 41 which is slidably connected to the inner wall of the water storage tank 2, and a support spring 42 is symmetrically fixedly connected to the upper surface of the pressure plate 41, and an adjusting plate 43 is fixedly connected to the upper ends of multiple support springs 42, and the adjusting plate 43 is slidably connected to the inner wall of the water storage tank 2, and a column 44 is symmetrically fixedly connected to the upper surface of the adjusting plate 43, and the two columns 44 are slidably connected to the top of the treatment box 1, and grooves 45 are equidistantly provided on the surface of the column 44, and the groove wall of the groove 45 is rotatably connected to the first limit block and the second limit block, and the top upper surface of the treatment box 1 is located next to the column 44 and is slidably connected to the first rack column 46 and the second rack column 47, and the surface of the first rack column 46 close to the column 44 is fixedly connected to the convex column 48, and a transmission gear 49 is meshed and connected between the first rack column 46 and the second rack column 47, and the two transmission gears 49 are rotatably connected to the top upper surface of the treatment box 1, and one end of the second rack column 47 A lifting column 410 is slidably connected, and both lifting columns 410 are slidably connected to the side of the processing box 1. The lower end of the lifting column 410 is rotatably connected to the first connecting rod 411, and the end of the first connecting rod 411 away from the lifting column 410 is fixedly connected to the connecting column 412, and the second connecting rod 413 is slidably connected in the connecting column 412. A trapezoidal groove 414 is provided on the surface of the second connecting rod 413 near the end of the first connecting rod 411, and a trapezoidal block 415 is installed on the groove wall of the trapezoidal groove 414. A pressure column 416 is fixedly connected to the surface of the trapezoidal block 415 away from the trapezoidal groove 414, and a first spring 417 is sleeved on the outer side of the pressure column 416. A first mounting block 418 is fixedly connected to the surface of the connecting column 412, and a second mounting block 419 is rotatably connected to the surface of the first mounting block 418. The second mounting block 419 is slidably connected to the pressure column 416, and a circular hole is provided at the center of the top upper surface of the processing box 1.

[0040] It should be noted that, in the process of adjusting and rotating the material holding box 61, the second connecting rod 413 moves with the rotation of the material holding box 61, and the initial state of the first spring 417 is a compressed state. Under the elastic force of the first spring 417, the trapezoidal block 415 cooperates with the trapezoidal groove 414 to form a restriction on the second connecting rod 413 and the connecting column 412, so that the movement of the second connecting rod 413 can drive the connecting column 412 to move together, and the first inclined groove 421 and the second inclined groove 422 are relatively moved, thereby adjusting the movement of the second rack column 47, which is driven by the transmission gear 49, and the first rack column 46 and the protruding column 48 move together, and the protruding column 48 and the groove 45 are relatively moved, driving the column 44 to move downward, and the adjusting plate 43 moves together with the column 44, and the supporting spring 42 is compressed, driving the pressing plate 41 to move downward, and the water inside the water storage tank 2 can be sprayed from the nozzle 3 Out, spray dust removal is carried out until the protrusion of the second inclined groove 422 on the surface of the lifting column 410 moves to one end of the first inclined groove 421, the trapezoidal block 415 can be separated from the trapezoidal groove 414, and the second connecting rod 413 and the connecting column 412 produce relative movement. The movement of the second connecting rod 413 cannot drive the first connecting rod 411 and the lifting column 410 to move. That is, in the process of adjusting and rotating the material box 61, whether adding concrete waste or conveying concrete waste into the processing box 1, the nozzle 3 can spray water to remove dust. The material box 61 can be adjusted and rotated to dump the concrete waste into the processing box 1. Spray dust removal can also be carried out in the process of crushing the concrete waste by the two crushing rollers 11. Spray dust removal increases the scope of spray dust removal, can effectively suppress the generation and spread of dust, and reduce pollution to the environment.

[0041] When relative movement occurs between the boss 48 and the groove 45, the boss 48 can contact the surfaces of the first limit block and the second limit block and produce relative movement. After the boss 48 is separated from the first limit block and the second limit block, the first limit block and the second limit block can return to their original state under the action of their own gravity, and when the boss 48 contacts the groove 45 again, it can assist the boss 48 to enter the next groove 45.

[0042] The upper surface of the pressure plate 41 is symmetrically fixedly connected with a fixing column 420, and the support spring 42 is sleeved on the outer side of the fixing column 420;

[0043] It should be noted that when water is added to the water tank 2, the pressure plate 41 moves toward the direction close to the adjustment plate 43 and is restricted by the fixed column 420. There is always a distance between the adjustment plate 43 and the pressure plate 41 to avoid plastic deformation of the support spring 42.

[0044] A U-shaped friction plate is symmetrically fixedly connected to the top surface of the processing box 1, and the U-shaped friction plate is installed in coordination with the column 44;

[0045] It should be noted that the setting of the U-shaped friction plate can restrict the column 44, and after the relative movement between the protruding column 48 and the groove 45 occurs, the column 44 can maintain the adjusted state.

[0046] A first inclined groove 421 is formed on the end surface of the second rack column 47 close to the lifting column 410, and a second inclined groove 422 is formed on the upper end surface of the lifting column 410. The first inclined groove 421 is slidably connected with the second inclined groove 422.

[0047] It should be noted that the provision of the first inclined groove 421 and the second inclined groove 422 can connect the second rack column 47 and the lifting column 410 together, so that the movement of the lifting column 410 can drive the second rack column 47 to move.

[0048] A connecting groove is formed on the end surface of the connecting column 412 away from the first connecting rod 411, and the connecting groove is slidably connected to the second connecting rod 413;

[0049] It should be noted that the connection groove can play a connecting role, so that the second connection rod 413 can be adjusted and rotated to drive the first connection rod 411 to rotate together.

[0050] The feeding mechanism 6 includes a material holding box 61 installed on the surface of the rotating block 5 through a torsion spring, and a baffle 62 is symmetrically slidably connected to one end of the surface of the material holding box 61 away from the processing box 1, and a first rotating column 63 is installed below the baffle 62 through a torsion spring, and an L-shaped column 64 is slidably connected to one end of the surface of the first rotating column 63 away from the baffle 62, and the two L-shaped columns 64 are rotatably connected, and the ends of the two second connecting rods 413 away from the connecting column 412 are both rotatably connected to the material holding box 61;

[0051] One end of the surface of the processing box 1 away from the baffle 62 is rotatably connected with a rotating plate 65, and two side surfaces of the rotating plate 65 are fixedly connected with a cylinder 66, and a spiral groove 67 and a strip groove are provided on the outer side of the cylinder 66, and the strip groove is connected with the spiral groove 67. A cylinder 68 is sleeved on the outer side of the cylinder 66, and a protrusion 69 is fixedly connected to the inner wall of the cylinder 68, and the protrusion 69 is installed in cooperation with the spiral groove 67. An annular block 610 is fixedly connected to the outer side of the cylinder 68, and a cross bar 611 is slidably inserted into the inner side of the annular block 610. A return spring 612 is sleeved on the outer side of the cross bar 611, and one end of the two return springs 612 is fixedly connected to the material holding box 61, and the other end of the return spring 612 is fixedly connected to the annular block 610;

[0052] A transmission column 613 is fixedly connected inside the two rotating blocks 5, and the transmission column 613 is rotatably connected to the processing box 1. Both ends of the surface of the transmission column 613 are fixedly connected with a third gear 614, and the outer side of the third gear 614 is meshedly connected with a third rack column 615. Both third rack columns 615 are slidably connected to the processing box 1. Both ends of one of the crushing rollers 11 are fixedly connected with a fourth gear 616, and the upper part of the fourth gear 616 is meshedly connected with a fifth gear 617. A cam 618 is fixedly connected to the surface of the fifth gear 617, and the cam 618 is installed in coordination with the third rack column 615.

[0053] It should be noted that the first motor drives one of the first gears 12 to rotate, the two second gears are meshed and connected, and the other first gear 12 can rotate together with the two second gears. The two crushing rollers 11 can rotate at the same time and in opposite directions. The two fourth gears 616 rotate as the crushing rollers 11 rotate, the fifth gear 617 meshes with the fourth gear 616, and the fifth gear 617 rotates as the fourth gear 616 rotates. The cam 618 is fixedly connected to the fifth gear 617, and the cam 618 rotates as the fifth gear 617 rotates. Due to the gravity, one end of the third rack column 615 can always be in contact with the surface of the cam 618. As the cam 618 rotates, the third rack column 615 can move back and forth. The third rack column 615 meshes with the third gear 614, and then the transmission column 613 can be adjusted to rotate, that is, the rotation of the rotating block 5 can be adjusted. The back and forth movement of the third rack column 615 can drive the rotating block 5 to rotate repeatedly. The material box 61 and the rotating block 5 are installed through a torsion spring, which can also drive the material box 61 to rotate, so as to transport and load the concrete waste, and intermittent loading is performed as the crushing roller 11 rotates;

[0054] When concrete waste is added into the material holding box 61 by a forklift or a conveyor belt, due to the gravity of the concrete itself, the material holding box 61 and the rotating block 5 can generate relative rotation, and then, the ends of the two L-shaped columns 64 away from the first rotating column 63 will contact the surface of the processing box 1, and the angle between the two L-shaped columns 64 will gradually increase. The two baffles 62 are adjusted and moved, and the material holding box 61 gradually tilts, and the concrete waste can slide down from between the two baffles 62, that is, the amount of concrete waste that the material holding box 61 can hold at one time is limited, which is equivalent to the amount of concrete waste that enters the processing box 1 at one time. The equipment is protected. Compared with the feeding method of vibration feeding, dust is continuously generated, which can reduce the scope of spray dust removal and make the spray dust removal effect better;

[0055] When the material holding box 61 is adjusted to rotate and the concrete waste is transported into the treatment box 1, the cylinder 68 can contact the inner wall surface of the treatment box 1. Since the surface of the treatment box 1 is inclined near the cylinder 68, the cylinder 68 rotates with the rotation of the material holding box 61. The cylinder 68 moves toward the direction close to the material holding box 61, and the annular block 610 moves with the movement of the cylinder 68. The reset spring 612 is compressed, and relative movement occurs between the protrusion 69 and the spiral groove 67, thereby driving the cylinder 66 to rotate, and the rotating plate 65 rotates with the cylinder 66, that is, the rotating plate 65 can be automatically opened. After the concrete waste is transported, it can be restored to its initial state under the elastic force of the reset spring 612, without affecting the material holding box 61 containing concrete waste.

[0056] A bottom plate 619 is slidably connected to the upper surface of the bottom of the material holding box 61;

[0057] It should be noted that the bottom plate 619 can slide a certain distance when the material box 61 is conveying the concrete waste into the processing box 1, thereby filling the gap between the material box 61 and the processing box 1 and ensuring stable conveying and loading of the concrete waste.

[0058] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
