Meeting the ecological requirements at the development of a clover thresher-separator

BACKGROUND: The paper considers the issues of environmental requirements in the development of the KS-1.0 clover thresher-separator with a capacity of 1.0...1.3 t/h. The KC-1.0 clover thresher-separator ensures not only high performance, but also meets environmental standards. In order to guarantee complete purification of the used air, a three-stage purification system has been developed. It includes a rotary cross-flow dust collector, a cyclone and a fabric filter. This system ensures the effective removal of dust and pollutants from the air, which is of great importance for ensuring environmental safety. It is important to note that when the clover thresher-separator operates indoors, the dust level of the air in the working area is only 6.8 mg/m3. This is well below the maximum permissible level and guarantees a safe environment for staff. In addition, when the used air is removed outside the room, environmental safety is achieved even without the use of a fabric filter. The dust content in the air does not exceed 15 g/m3, which also complies with the established standards. Thus, the KS-1.0 clover thresher-separator ensures high productivity during processing as well as environmental safety. Given the use of a suction air flow and the three-stage cleaning system, this machine minimizes emissions of harmful substances and ensures safe conditions for personnel and the environment. AIM: Research and analysis of the compliance of the KS-1.0 clover thresher-separator with the environmental requirements. METHODS: During the research, a prototype of the KS-1.0 clover thresher-separator was tested indoors when operating the Dymkovsky variety clover seeds, and the efficiency of all dust collecting devices with various material supply q was defined according to the well-known methods. RESULTS: Environmental safety and sanitary and hygienic conditions for service personnel are ensured through the use of a suction air flow in a pneumatic separation channel and a sedimentation chamber. CONCLUSION: It was found that when the machine is operating indoors, the dust content of the air in the working area is 6.8 mg/m3. When removing the used air outside the room, environmental safety is achieved without a fabric filter (the dust content in the air does not exceed 15 g/m3).
