Problems solved by technology

[0002] In some mining machinery, there is a certain pressure difference between the material outlet and the material inlet of the equipment and the outside world. During production, the gas of the equipment is ventilated from the material inlet and outlet to the outside of the equipment under the action of the pressure difference, which not only leads to energy loss. Waste, and the gas that runs out is often mixed with dust, which not only affects the operation and health of the on-site staff, but also leaves a safety hazard of dust explosion. Therefore, it is necessary to install a sealing device at the inlet and outlet. Not only to ensure safety and reliability, but also to make it low cost, easy to disassemble and assemble, and have a long service life. At the same time, it is also necessary to maintain the pressure difference in the equipment so as not to affect the normal operation of the equipment

Abstract

The invention discloses a material opening sealing device which comprises a material barrel, wherein a seal sleeve sticks to the upper end of the material barrel; the lower end of the seal sleeve sticks to the lower part of the material barrel; the seal sleeve adopts an inward arc-shaped round sleeve structure; a valve is arranged on the inner middle wall of the inward arc-shaped round sleeve structure and comprises two crescent sheets which are opposite to each other; the root parts of the crescent sheets are connected with the inner wall of the seal sleeve; and the free edges of the crescent sheets face a material flowing direction. The material opening sealing device provided by the invention is simple in structure and convenient to mount and dismount, has a good sealing effect, is safe and reliable, and scarcely affects the structure and normal operation of an equipment body. Meanwhile, through an improvement on the material of the sealing device, the sealing device achieves better mechanical properties and a longer service life, and the corresponding replacement cost is lowered.
