DETAILED DESCRIPTION

[0019] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-4 The device for processing construction waste shown in the figure comprises a processing box 1, a base 2 is provided at the bottom of the processing box 1, two crushing rollers 103 that cooperate with each other are provided inside the processing box 1, one end of each crushing roller 103 passes through the processing box 1 and is fixedly connected to mutually meshing gears 102, a motor 101 is provided on one side of the processing box 1, the output shaft of the motor 101 is fixedly connected to one end of the adjacent crushing roller 103, a mounting cavity 104 is provided on the other side of the processing box 1 above the crushing roller 103, a liquid storage chamber 201 is provided inside the base 2, and dust reduction water is provided inside the liquid storage chamber 201; a dust suction mechanism 3 is provided on one side of the processing box 1, and the dust suction mechanism 3 is used to collect dust generated during the crushing process; a dust reduction mechanism 4 is provided inside the liquid storage chamber 201, and the dust reduction mechanism 4 is used to reduce dust;

[0021] The construction waste is put into the processing box 1 from the top opening. By starting the motor 101, the crushing roller 103 connected to it can be driven to rotate under the action of the motor 101, and the two crushing rollers 103 can be driven to rotate together under the joint action of the two mutually meshing gears 102, and the rotation directions are opposite, so as to achieve the purpose of crushing the construction waste.

[0022] The dust collection mechanism 3 includes a mounting shell 301 fixedly connected to one side of the processing box 1. The interior of the mounting shell 301 is connected to the mounting chamber 104 to form a collection chamber. A baffle 305 is fixedly connected to the inner wall of the mounting chamber 104. The surface of the baffle 305 is rotatably connected to a rotating shaft 303. The other end of the rotating shaft 303 passes through the collection chamber and is rotatably connected to the inner wall of the mounting shell 301. A transmission mechanism 306 is provided on the surface of the rotating shaft 303. The other end of the transmission mechanism 306 is fixedly connected to the end of the adjacent crushing roller 103. A scraper 304 is fixedly connected to the surface of the rotating shaft 303. The side of the scraper 304 away from the rotating shaft 303 contacts the inner wall of the collection chamber.

[0023] In the process of driving the crushing roller 103 to rotate, the rotating shaft 303 can be driven to rotate synchronously through the transmission mechanism 306. The transmission mechanism 306 is a relatively mature component in existing technical applications. It consists of two transmission wheels and a transmission belt. By driving one of the transmission wheels to rotate, the other transmission belt can be driven to rotate under the action of the transmission belt, and then the scraper 304 can be driven to rotate under the action of the rotating shaft 303.

[0024] A connecting shell 310 is fixedly connected to the side of the mounting shell 301 away from the processing box 1. A fan 311 is disposed inside the connecting shell 310. A cavity 302 is formed on the side of the mounting shell 301 away from the processing box 1 and is symmetrically distributed with the baffle 305. A through groove is formed on the surface of the connecting shell 310 and is connected to the cavity 302. A filter plate 309 is fixedly connected to the inner wall of the cavity 302. The surface of the filter plate 309 contacts the surface of the scraper 304.

[0025] Since the baffle 305 blocks the lower half of the installation chamber 104 and cooperates with the cavity 302 opened in the upper half of the installation shell 301, when the airflow is guided by starting the fan 311, the dust passes through the upper half of the installation chamber 104 and enters the interior of the collection chamber together with the airflow. At this time, the airflow can pass through the filter plate 309 normally, and the dust is trapped in the interior of the collection chamber. Under the action of the rotation of the rotating shaft 303, the scraper 304 pushes the dust collected in the upper half of the collection chamber to rotate together with the scraper 304. When the dust between two adjacent scrapers 304 moves to the lower half of the collection chamber, it is blocked by the two scrapers 304 from communicating with the cavity 302. Therefore, there is no interference from the airflow, so that the collected dust can fall freely under the action of gravity.

[0026] A connection box 307 communicating with the collection chamber is provided at the bottom of the mounting shell 301. A conduit 308 is fixedly connected to the bottom of the connection box 307. The lower end of the conduit 308 passes through the base 2 and extends to the interior of the liquid storage chamber 201.

[0027] The freely falling dust can be introduced into the interior of the conduit 308 through the connection box 307, and then introduced into the interior of the liquid storage chamber 201 under the action of the conduit 308, so that the dust can be treated by the dust reduction water filled in the liquid storage chamber 201;

[0028] The dust suppression mechanism 4 includes a partition 402 fixedly connected to the inner wall of the liquid storage chamber 201. A filter screen 405 is embedded in the surface of the partition 402. A sedimentation chamber is formed between the bottom of the partition 402 and the interior of the liquid storage chamber 201. The lower end of the conduit 308 passes through the partition 402 and is connected to the sedimentation chamber.

[0029] The dust introduced into the sedimentation chamber through the conduit 308 can be fully combined with water to achieve sedimentation treatment, and the filter 405 can reduce the dust from entering the space above the partition 402, so that the dust can be settled in the sedimentation chamber for easy cleaning;

[0030] A pump body 401 is provided on the top of the partition 402. The liquid outlet end of the pump body 401 is connected to a liquid outlet pipe 406. The other end of the liquid outlet pipe 406 passes through the base 2 and is connected to a communication shell 407. The surface of the communication shell 407 is connected to evenly distributed nozzles 408. The other end of the nozzle 408 extends into the interior of the processing box 1 and is located above the crushing roller 103.

[0031] The dust reduction water stored in the liquid storage chamber 201 can be introduced into the interior of the nozzle 408 through the liquid outlet pipe 406 and the connecting shell 407 under the action of the pump body 401, and the water is sprayed into the interior of the treatment box 1 under the action of the nozzle 408 to reduce the dust generated by the crushing. In conjunction with the dust collection mechanism 3, the dust reduction treatment effect of the dust is effectively improved, and the pollution of the dust generated during the crushing process to the environment is reduced. Among them, the pump body 401 is preferably a sewage pump or a solid-liquid mixing pump;

[0032] The bottom of the processing box 1 is connected to a collecting shell 404 , and the bottom of the collecting shell 404 is connected to evenly distributed connecting pipes 403 . The other end of the connecting pipe 403 passes through the partition 402 and is connected to the precipitation chamber.

[0033] A material guide plate is fixedly connected to the inner wall of the processing box 1, and evenly distributed water holes are opened on the surface of the material guide plate. The crushed construction waste is discharged from the interior of the processing box 1 through the material guide plate, and the dust-reduced water can be introduced into the interior of the collection shell 404 through the water holes, and under the action of the connecting pipe 403, the dust-reduced water is introduced into the interior of the sedimentation chamber for sedimentation treatment, thereby realizing the recycling of water and reducing the use cost.

[0034] Working principle: Construction waste is put into the processing box 1 from the top opening. By starting the motor 101, the two crushing rollers 103 can be driven by the motor 101 to crush the construction waste in cooperation with the two meshing gears 102. In this process, the fan 311 and the pump body 401 are started, and the dust generated in the crushing process can be adsorbed and collected under the action of the dust suction mechanism 3, and the collected dust can be introduced into the dust reduction water for dust reduction treatment. At the same time, the dust reduction treatment of the dust can be achieved under the action of the dust reduction mechanism 4. The cooperation between the two effectively reduces the pollution of the environment to the dust generated in the crushing process.
