Description

Technical Field

[0001] The present invention relates to the technical field of building material recycling, and in particular to a processing device and method for recycling and reusing building materials. Background Art

[0002] Building materials are a general term for materials used in civil engineering and construction projects. Incomplete bricks, broken tiles, ceramic tiles, etc. in construction waste materials can be recycled and crushed to make foundations or other uses.

[0003] When recycling discarded bricks and stones, crushers are usually used to crush large and irregular bricks into small pieces, so as to facilitate subsequent transportation and use. Existing crushers will generate a lot of dust when crushing bricks and stones. The dust will spread into the air, causing pollution to the environment, and will also be easily inhaled into the lungs by workers, endangering their health. In addition, since discarded bricks, stones and other building materials are usually directly piled on the ground, bricks and stones are easily mixed with debris such as leaves and branches, which will also be mixed together when crushed, thus affecting the use of the crushed building materials.

[0033] like Figure 2-3 As shown, when it is necessary to crush building materials such as stones and bricks, first fill the first collecting frame 3, the second collecting frame 4 and the crusher 2 with water, then start the crusher 2 and put stones or bricks into the crusher 2; as the crusher 2 runs, the stones will be crushed, and the dust generated when the stones are crushed will directly blend into the water and will not spread into the air, thereby protecting the environment;

[0034] The crushed stones will directly fall into the first collecting frame 3. When there is a certain amount of crushed stones in the first collecting frame 3, the docking mechanism is started, and the docking mechanism will dock the second collecting frame 4 located at the bottom of the crusher 2 with the first collecting frame 3. At this time, the crushed stones in the first collecting frame 3 will enter the second collecting frame 4, and then the replacement mechanism is started, and the replacement mechanism will drive the second collecting frame 4 to disengage from the first collecting frame 3, and drive the other second collecting frame 4 to move to the bottom position of the first collecting frame 3; by alternately docking the two second collecting frames 4 with the first collecting frame 3, the crushed stones or bricks can be discharged while ensuring that the water volume in the crusher 2 and the first collecting frame 3 remains unchanged; the device has a simple structure and is easy to use. When crushing stones and bricks, it can effectively prevent dust from spreading into the air, causing air pollution and endangering the health of workers.

[0035] like Figure 3-5 , Figure 8 As shown, as a further solution of the present invention, the docking mechanism includes a first cylinder 5, the first cylinder 5 is fixedly connected to the bottom plate 1 and a push plate 6 is fixedly connected to the telescopic end of the first cylinder 5, and a first push rod 7 is fixedly connected to the push plate 6; a sealing plate 8 is provided at the bottom position of the second collection frame 4, and a second push rod 9 is fixedly connected to the bottom end of the sealing plate 8, the second push rod 9 is slidably connected to the second collection frame 4 and a spring 10 is sleeved on the second push rod, one end of the spring 10 is fixedly connected to the second collection frame 4 and the other end of the spring 10 is fixedly connected to the second push rod 9; a connecting mechanism is provided on the first collection frame 3, and the connecting mechanism is used to connect the first collection frame 3 and the second collection frame 4 with each other after the first collection frame 3 and the second collection frame 4 are docked, and to seal the first collection frame 3 after the first collection frame 3 and the second collection frame 4 are separated;

[0036] The connection mechanism includes a sliding frame 11, which is sleeved on the first push rod 7 and has clearance fit with the first push rod 7; two connecting rods 12 are symmetrically rotatably connected to the left and right sides of the sliding frame 11, and the other ends of the two connecting rods 12 on the left and right sides are rotatably connected to baffles 13, and the two baffles 13 are symmetrically distributed on the left and right sides of the bottom of the first collection frame 3, and the two baffles 13 are slidably connected to the first collection frame 3;

[0037] The distance between the sliding frame 11 and the push plate 6 is equal to the distance between the first collecting frame 3 and the second collecting frame 4, and the length of the second push rod 9 located at the bottom side of the second collecting frame 4 is greater than the distance between the first collecting frame 3 and the second collecting frame 4;

[0038] When working, when it is necessary to drive the second collecting frame 4 at the bottom position of the crusher 2 to dock with the first collecting frame 3, the first cylinder 5 is started at this time, and the first cylinder 5 pushes the push plate 6 and the first push rod 7 to move upward, and the first push rod 7 will push the second push rod 9 to move upward, and the second push rod 9 drives the sealing plate 8 to move upward; because the weight of the water in the second collecting frame 4 is mainly borne by the sealing plate 8, when the second push rod 9 moves upward, the second push rod 9 can easily drive the second collecting frame 4 to move upward through the spring 10; when the second collecting frame 4 moves upward to the position docking with the first collecting frame 3, the push plate 6 just fits with the sliding frame 11; when the first cylinder 5 drives the push plate 6 and the first push rod 7 to continue to move upward, the push plate 6 pushes the sliding frame 11 to move upward, and when the sliding frame 11 moves upward, it will drive the baffles 13 on the left and right sides of the first collecting frame 3 to move through the connecting rods 12 on the left and right sides, and the baffles 13 on the left and right sides begin to slide to the left and right positions respectively, and the first collecting frame 3 and the second The collecting frame 4 is connected; at this time, since the first collecting frame 3 and the second collecting frame 4 are connected, the water in the first collecting frame 3 and the pulverizer 2 will first fill the second collecting frame 4, so the water level in the pulverizer 2 will drop; the first push rod 7 will push the second push rod 9 to move upward, and the second push rod 9 will drive the sealing plate 8 to move upward, and the space in the second collecting frame 4 will become smaller, so that the water level in the pulverizer 2 will not drop, and the dust removal effect of the pulverizer 2 during pulverization is guaranteed; when a certain amount of gravel is collected in the second collecting frame 4, the first cylinder 5 is driven to contract, and the first cylinder 5 will drive the push plate 6 and the first push rod 7 to move downward, and the sliding frame 11 and the second push rod 9 will move downward accordingly, and the spring 10 will gradually reset; when the sliding frame 11 moves downward, it will drive the baffles 13 on both sides to gradually close through the connecting rod 12.

[0039] like Figure 3 , Figure 6-9 As shown, as a further solution of the present invention, the replacement mechanism includes four support frames 14, which are symmetrically distributed at four positions of the bottom plate 1 and are fixedly connected to the bottom plate 1; a sliding rod 15 is provided between the two second collection frames 4, and the first sliders 16 are symmetrically fixedly connected to the front and rear sides of the sliding rod 15, and the first sliders 16 on the front and rear sides are respectively slidably connected to the support frames 14 on the front and rear sides; a plurality of driving wheels 17 are provided at the bottom of the first slider 16, and the driving wheels 17 are rollingly matched with the support frames 14; connecting mechanisms are symmetrically provided at the left and right ends of the sliding rod 15, and the connecting mechanisms are used to connect the second collection frame 4 with the sliding rod 15;

[0041] During operation, when the second collecting frame 4 needs to be replaced, the driving wheel 17 on the first slider 16 rotates, which drives the first slider 16 to move on the support frame 14, and the first sliders 16 on the front and rear sides drive the sliding rod 15 to move to the left, and when the sliding rod 15 moves to the left, it drives the two second collecting frames 4 to move to the left. When the second collecting frame 4 on the right side moves to the bottom position of the crusher 2, the driving wheel 17 is stopped at this time, and then the first cylinder 5 can be started to push the second collecting frame 4 to move upward, and the second collecting frame 4 will drive the second slider 20 to slide upward in the slide groove 19.

When the rotating block 18 on the left rotates downward at an angle exceeding ninety degrees, the second collecting frame 4 connected to the rotating block 18 will begin to be in a downward state, and the water and gravel inside it will fall directly from the second collecting frame 4. After the gravel has fallen from the second collecting frame 4, the two second cylinders 22 on the left are started to drive the rotating block 18 on the left to rotate and reset, and the rotating block 18 on the left drives the second collecting frame 4 on the left to reset.
