Description

Technical Field

[0001] The present invention belongs to the technical field of construction waste treatment, and specifically refers to a device for treating civil engineering construction waste. Background Art

[0002] Civil engineering construction waste mainly refers to the waste generated during construction, demolition, and decoration processes, including waste concrete blocks, waste bricks, waste metals, waste plastics, and waste wood, etc. Among them, waste concrete - type waste accounts for the largest proportion. If these construction wastes are not properly treated, they will cause serious environmental pollution. Therefore, it is necessary to treat, recycle, and reuse construction waste to reduce environmental pollution and improve the resource utilization rate.

[0003] In the current construction waste treatment process, construction workers transport the on - site construction waste to the waste treatment plant for centralized treatment through transport vehicles. The treatment cycle is relatively long, and a large amount of dust will be generated during the on - site waste handling operation, requiring additional dust - suppression devices, which consume a lot of manpower and material resources. Most of the existing construction waste treatment devices are fixed equipment. It is necessary for workers to pour construction waste into the waste treatment device manually. The large - volume crushed stone waste is crushed into slag by a gear crusher, and the metal and concrete are separated through manual sorting or simple mechanical sorting, which is time - consuming and laborious. Moreover, the waste treatment device is large in volume, fixed in layout, and not flexible enough in operation.

[0004] Therefore, it is necessary to propose a device for treating civil engineering construction waste to solve the technical problems existing in the current construction waste treatment process. Summary of the Invention

[0005] To solve the above - mentioned existing problems, the present invention provides a device for treating civil engineering construction waste. This device can move flexibly through moving crawler wheels, realizing on - site collection and treatment of construction waste, reducing the time for waste transportation and centralized treatment, saving time and effort. The material - shoveling bucket can dial the construction waste into the aggregate cylinder. The lifting hydraulic push rod can drive the aggregate cylinder to rotate upward, making the construction waste slide along the inner wall of the aggregate cylinder to the rotating piece, and forming slag through the coarse - crushing process of the coarse - crushing roller. The rotating cylinder can rotate repeatedly to drive the aggregate cylinder to lift or lower repeatedly, so that the construction waste is repeatedly crushed by the coarse - crushing roller in the aggregate cylinder, thereby increasing the degree of crushing of the construction waste and facilitating the subsequent fine - crushing and separation processes. The rotating shaft can drive the rotating piece to rotate, dial the coarsely - crushed construction waste into the crushing treatment box, form smaller - volume slag through the refined crushing of the fine - crushing roller, and send it into the separation box through the conveyor belt. Through the magnetic adsorption of the permanent - magnet iron - removing roller, the metal substances in the waste slag are screened out, achieving the technical effect of classifying and recycling the concrete and metal substances in the construction waste.

[0013] Further, the rear end of the separation box is arranged to slope downward from front to back.

The permanent magnet iron removal roller is rotatably arranged on the front side of the separation plate.

[0017] Further, the main controller adopts Siemens S7-400.

[0018] The beneficial effects obtained by the present invention with the above structure are as follows:

[0019] (1) The device realizes flexible movement through the moving crawler wheels, realizes on-site collection and treatment of construction waste, reduces the time for waste transportation and centralized treatment, and saves time and effort;

[0020] (2) When collecting waste, the hydraulic push rod is lifted to drive the collecting barrel to rotate downward, so that the end opening of the collecting barrel faces the construction waste piled below. The shovel bucket can push the construction waste into the collecting barrel and close the end opening of the collecting barrel. The hydraulic push rod is lifted to drive the collecting barrel to rotate upward, so that the construction waste slides along the inner wall of the collecting barrel to the rotating plate. At this time, the coarse crushing roller rotates synchronously under the drive of the first driving mechanism. The construction waste is crushed into slag after the coarse crushing process of the coarse crushing roller. The rotating plate can prevent the construction waste from entering the crushing treatment box. The rotating barrel can rotate repeatedly to drive the collecting barrel to lift or lower, so that the construction waste is repeatedly crushed by the coarse crushing roller in the collecting barrel, thereby increasing the crushing degree of the construction waste and facilitating the subsequent fine crushing and separation process;

[0021] (3) After the rough crushing process of the construction waste is completed, the rotating shaft can drive the rotating sheet to rotate, and the roughly crushed construction waste is transferred into the crushing treatment box. The fine crushing roller can finely crush the construction waste to form smaller slag, which then falls onto the conveyor belt and is sent to the separation box through the conveyor belt for subsequent screening treatment;

[0022] (4) When the construction waste is transported on the conveyor belt, the permanent magnetic iron removal roller rotates continuously. Through the magnetic adsorption effect of the permanent magnetic iron removal roller, the metal substances in the waste slag on the conveyor belt are sucked out and attached to the outer wall of the permanent magnetic iron removal roller, and move to the position of the magnetic isolation plate as the permanent magnetic iron removal roller rotates. The magnetic isolation plate separates the metal adsorbed on the permanent magnetic iron removal roller from the surface of the permanent magnetic iron removal roller, so that the metal in the waste slides along the magnetic isolation plate and the separation plate and slides out from the upper discharge port, while other construction waste (mainly concrete slag) will fall along the conveyor belt into the lower discharge port, achieving the technical effect of classified recycling of concrete and metal substances in construction waste;

[0023] (5) The second driving mechanism can drive the paired fine crushing rollers to rotate synchronously. At the same time, one of the fine crushing rollers drives the synchronous rod to rotate together when rotating. The synchronous rod drives the synchronous belt wheel to rotate. The synchronous belt wheel will drive the separation belt wheel to rotate through the first synchronous belt, so that the permanent magnetic iron removal roller will rotate synchronously. The synchronous belt wheel can also drive the transport belt wheel to rotate through the second synchronous belt, so that the transport belt wheel drives the conveyor belt to move, thereby achieving the technical effect of the linkage operation of the rotation of the fine crushing roller, the rotation of the permanent magnetic iron removal roller and the movement of the conveyor belt, thereby reducing the use of electronic components;

[0024] (6) When the device is processing construction waste, the water guide pump valve will be started synchronously to transport the water stored in the water tank to the water guide pipe and spray it out through the dust suppression nozzle to form water mist on the left and right sides of the device, so as to reduce the dust generated during the construction waste treatment process and reduce the pollution of the smoke to the environment;

[0025] (7) The construction waste treatment process of this device occurs successively inside the aggregate cylinder, rotating cylinder, crushing treatment box, and separation box. The dust generated when the coarse crushing roller and the fine crushing roller crush the construction waste will be confined within a closed space, thereby reducing the spread of dust, environmental pollution, and the impact on the physical health of construction workers.

[0050] Working principle and working process:

[0051] Before the construction waste is crushed, it needs to be preliminarily sorted. The preliminary sorting process can be realized by manual or automated mechanical means. The preliminary sorting process belongs to the prior art and will not be elaborated here. After the preliminary sorting, the construction waste can be piled up in the treatment area for the subsequent crushing process. The construction workers can send instructions to the main controller 13 through the remote control device. The main controller 13 controls the corresponding components of the device according to the instructions of the remote control device to realize the automated operation of the device, thereby reducing the manual operation process. The remote control device belongs to the prior art and will not be elaborated again; when in use, the construction workers control the device to move to the waste pile where the construction waste needs to be processed through the remote control device. The device realizes flexible movement through the moving crawler wheels 11, realizes the on-site collection and treatment of the construction waste, and reduces the time for waste transportation and centralized treatment, saving time and effort.

[0052] When collecting waste, the output end of the lifting hydraulic push rod 14 retracts. The aggregate cylinder 3 rotates downward under the drive of the lifting hydraulic push rod 14, so that the end opening of the aggregate cylinder 3 faces the construction waste piled up below. When the output end of the control push rod 311 extends forward, the material shoveling bucket 31 rotates downward under the push of the output end of the control push rod 311, shovels the construction waste, shovels the construction waste into the aggregate cylinder 3, and closes the end opening of the aggregate cylinder 3. Figure 8In the first working condition shown, at this time, there is already some construction waste in the aggregate bin 3. At this time, the output end of the lifting hydraulic push rod 14 extends out again, pushing the aggregate bin 3 to rotate upward, so that the construction waste slides along the inner wall of the aggregate bin 3 towards the rotating piece 22. At this time, the first driving mechanism 321 drives the pair of coarse crushing rollers 32 to rotate synchronously. The construction waste forms slag through the coarse crushing process of the coarse crushing rollers 32. In the initial state, the position of the rotating piece 22 is as Figure 8 shown, one of the rotating pieces 22 is vertically arranged downward. At this time, the rotating piece 22 can block the construction waste from entering the crushing treatment box 4. At this time, the rotating cylinder 2 can rotate downward repeatedly to drive the aggregate bin 3 to descend again, so that the construction waste is crushed again by the coarse crushing rollers 32. The rotating cylinder 2 rotates repeatedly, causing the aggregate bin 3 to repeatedly lift or descend, so that the construction waste repeatedly passes through the crushing of the coarse crushing rollers 32 in the aggregate bin 3, thereby increasing the crushing degree of the construction waste and facilitating the subsequent fine crushing and separation processes. The coarse crushing rollers 32 are made of high-strength alloy steel, with the characteristics of high hardness, good wear resistance and excellent toughness, and can effectively resist the impact of construction waste.

[0053] After the coarse crushing process of the construction waste is completed, the aggregate bin 3 remains in the lifted state. At this time, the discharge port 23 is communicated with the crushing treatment box 4. The main controller 13 controls the shaft rotation motor 122 to start automatically, driving the rotating shaft 21 to rotate. The rotating shaft 21 can drive the rotating piece 22 to rotate 120 degrees, and the coarsely crushed construction waste is dialed into the crushing treatment box 4 from the discharge port 23. The fine crushing rollers 41 can finely crush the construction waste to form smaller slag, and the slag then falls onto the conveyor belt 43 and is sent to the separation box 5 by the conveyor belt 43 for subsequent screening treatment;

[0054] When the construction waste is conveyed on the conveyor belt 43, the permanent magnet iron removal roller 51 rotates continuously. Through the magnetic adsorption effect of the permanent magnet iron removal roller 51, the metal substances in the waste slag on the conveyor belt 43 are sucked out and attached to the outer wall of the permanent magnet iron removal roller 51, and move to the position of the magnetic isolation plate 53 as the permanent magnet iron removal roller 51 rotates. The magnetic isolation plate 53 separates the metal adsorbed on the permanent magnet iron removal roller 51 from the surface of the permanent magnet iron removal roller 51, so that the metal in the waste slides along the magnetic isolation plate 53 and the separation plate 52 and slides out from the upper discharge port 54, while other construction waste (mainly concrete slag) will fall into the lower discharge port 54 along the conveyor belt 43, achieving the technical effect of classified recycling of concrete and metal substances in the construction waste, as Figure 9 shown in the second working condition. Construction workers can externally connect an aggregate bin or an aggregate bag at the discharge port 54 to collect the concrete slag and metal waste respectively for subsequent use.

[0055] The second driving mechanism 411 can drive the paired fine crushing rollers 41 to rotate synchronously, and at the same time, one of the fine crushing rollers 41 drives the synchronous pulley 4121 to rotate through the synchronous rod 412, and the synchronous pulley 4121 drives the separation pulley 511 to rotate through the first synchronous belt 44, so that the permanent magnetic iron removal roller 51 rotates synchronously, and the synchronous pulley 4121 can also drive the transport pulley 421 to rotate through the second synchronous belt 45, so that the transport pulley 421 drives the conveyor belt 43 to move, so as to achieve the technical effect of the linkage operation of the rotation of the fine crushing roller 41, the rotation of the permanent magnetic iron removal roller 51 and the movement of the conveyor belt 43, thereby reducing the use of electronic components, such as Figure 6 shown.

[0056] When the device is treating construction waste, the water pump valve 61 will be started synchronously to transport the water stored in the water tank 6 to the water pipe 62 and spray it out through the dust reduction nozzle 621 to form water mist on the left and right sides of the device, so as to reduce the dust generated in the process of treating construction waste and reduce the pollution of the smoke to the environment.

[0057] The construction waste processing process of the device takes place in sequence inside the collecting drum 3, the rotating drum 2, the crushing processing box 4 and the separation box 5. The smoke and dust generated when the coarse crushing roller 32 and the fine crushing roller 41 crush the construction waste will be confined in a closed space, thereby reducing the diffusion of smoke and dust, reducing environmental pollution and the impact on the health of construction workers.

[0058] The above is the overall workflow of the present invention, and you can repeat this step next time you use it.

[0059] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
