DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-3As shown, a device for screening expanded perlite finished products includes a mounting shell 1, a discharge port is provided at the lower end of the mounting shell 1, a filtering mechanism for filtering perlite is provided in the mounting shell 1, and the filtering mechanism includes a plurality of flow guide covers 2 and a plurality of mounting rings 4 fixedly connected to the inner wall of the mounting shell 1, and a plurality of mounting rings 4 are provided with a shock absorbing assembly 5, and the shock absorbing assembly 5 includes a damper and a shock absorbing spring. It is a common device, so it is not described in detail. A first filter screen 3 and a second filter screen 7 are commonly provided on the plurality of shock absorbing assemblies 5, and the first filter screen 3 and the second filter screen 7 are both connected to a discharge pipe 9, and a vibration motor 6 is provided at the lower end of the first filter screen 3 and the second filter screen 7, and the portion of the middle part of the first filter screen 3 and the second filter screen 7 for installing the vibration motor 6 has no mesh.

[0022] The side wall of the mounting shell 1 is provided with two processing mechanisms for processing dust, and the processing mechanisms include two dust suction pipes 8 arranged on the mounting shell 1. The end of the dust suction pipe 8 away from the mounting shell 1 is connected to a processing barrel 13, and the two ends of the processing barrel 13 are respectively provided with an upper cover 14 and a lower cover 15. A fan 12 is provided on the upper cover 14, and a filter screen 11 is provided in the processing barrel 13.

[0023] In the present invention, the upper cover 14 is threadedly connected to the treatment barrel 13, and the filter screen 11 is threadedly connected to the treatment barrel 13, so that the filter screen 11 can be easily disassembled for replacement and maintenance.

[0024] In the present invention, the lower cover 15 is threadedly connected to the processing barrel 13, which facilitates cleaning of dust in the processing barrel 13. The processing barrel 13 is made of acrylic material, which facilitates observation of dust collection.

[0025] In the present invention, a discharge pipe 10 is provided at the lower end of the installation shell 1 to facilitate the discharge of materials in the installation shell 1 , and an inclined surface is provided at the bottom of the installation shell 1 .

[0026] In the present invention, the end of the discharge pipe 9 away from the mounting shell 1 is connected to a discharge shell 16, and the discharge shell 16 is rotatably connected to the discharge pipe 9 to facilitate the discharge of the discharge pipe 9 in different directions. After the equipment is installed in place, the discharge shell 16 and the discharge pipe 9 can be welded.

[0027] It should be noted that the utility model is a device for screening expanded perlite finished products. The user pours the perlite finished products into the guide cover 2, starts the two vibration motors 6, and the perlite finished products fall into the first filter screen 3. As the first filter screen 3 vibrates, large pieces of perlite finished products are discharged from the discharge pipe 9, and small pieces of perlite finished products pass through the mesh of the first filter screen 3 and enter the second filter screen 7 along the guide cover 2. As the second filter screen 7 vibrates, perlite finished products with a diameter larger than the mesh diameter of the second filter screen 7 are discharged from the discharge pipe 9 below, and perlite finished products with a diameter smaller than the mesh diameter of the second filter screen 7 fall from below. Multi-stage screening can be achieved in the process, and multiple guide covers 2 can be used to protect the screening process during the screening process to reduce dust emission.

[0028] In addition, the fan 12 can be started, and suction is generated in the dust suction pipe 8 to suck out the dust. After the dust enters the processing barrel 13, it is blocked by the filter 11 and remains in the processing barrel 13, which is convenient for subsequent centralized collection of the dust. The collected dust can be used for thermal insulation material reprocessing: the expanded perlite dust can be collected and used to manufacture thermal insulation materials, filling material applications, recycling value in the horticultural field, improving soil, and soilless cultivation substrates.
