In the threshing and redrying process, the grading and sorting of tobacco leaves is one of the key processes, and the process is mainly completed by a large amount of manpower. Due to the characteristics of tobacco materials, a large amount of absorbable dust is inevitably generated in the whole screening process, great harm is brought to the health and the production environment of workers, and meanwhile, the dust in the whole leaf selecting workshop is dense and the working environment is poor. Therefore, effective dust removal, environmental improvement and harm reduction are always pursued by redrying enterprises.
At present, most redrying enterprises mainly adopt two dust removal methods:
firstly, adopt the water smoke to spray and install the appropriate amount spray valve in whole workshop of selecting promptly, the spray valve connects the water under high pressure, forms the spraying. The dust is adsorbed by utilizing the spray, and fine dust droplets gradually fall to the ground under the action of gravity, so that the aim of dust fall is fulfilled. However, the method only settles the dust on the ground, the dust is not removed, the dust is changed into dust along with the loss of moisture, the dust on the ground is large, the dust on the ground can be lifted again due to the factors of personnel walking, object movement and the like, and the dust settling problem cannot be thoroughly solved.
The second method is to install an environmental dust removal system in the whole plant and adopt an industrial cloth bag dust removal system. Dust in the air is adsorbed and removed by a strong negative pressure. The method has the advantages of thorough dust removal and meeting the requirement of environmental sanitation. The method is characterized in that dust is removed firstly, timeliness is poor, and people is not oriented because the dust is generally contacted with people firstly when leaves are selected manually.

Detailed Description
The technical solutions provided by the present invention will be described in detail below with reference to specific examples, and it should be understood that the following specific embodiments are only illustrative of the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1-3, the integrated leaf selecting and dust removing workbench provided by the invention comprises a leaf selecting platform 8, a blanking chamber 9 and a negative pressure dust removing chamber 10. The leaf selection district platform is formed by stainless steel square pipe and pipe welding, and the platform surface is the screen cloth style, and the bits can fall to the blanking room from the platform. The blanking chamber and the negative pressure dust removal chamber are arranged below the leaf selecting table.
The blanking chamber mainly comprises a filter screen 5 and a closed drawer 6, is positioned right below the outlet of the hopper of the leaf selecting area and is used for collecting tobacco leaf fragments and dust, and the whole blanking chamber is a closed space. The filter screen 5 is made of a screen mesh with larger meshes and is mainly used for isolating larger fragments which are regularly cleaned by a manual brush and fall into a closed drawer below.
