Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of dangerous waste treatment technology, specifically relates to a dangerous solid waste crusher feeding opening anti -leak device. BACKGROUND

[0002] With the development of economic technology and the continuous strengthening of environmental protection requirements, the harmless treatment of dangerous solid waste is paid more and more attention. Incineration is one of the effective ways of harmless treatment of dangerous solid waste, and the dangerous solid waste needs to be crushed by a crusher before incineration to obtain better incineration efficiency and pollutant removal effect. A large amount of dust, splashes and harmful gases are generated during the use of the crusher, and leakage often occurs at the feeding opening of the crusher due to poor sealing, which seriously pollutes the environment and endangers the health of the operators. In order to prevent dust, splashes and harmful gases from leaking at the feeding opening, a high-efficiency dangerous waste blowing crusher (application number 202122397627.3) is provided with a rotating shaft in the feeding hopper and four discharge rotating plates fixed on the side wall of the rotating shaft in the feeding hopper; a crushing device for dangerous waste incineration treatment (application number 202222326338.9) is provided with an isolation cover fixedly connected to the upper end of the crusher main body, a feeding opening is formed on one side of the isolation cover, and a dust suction port is fixedly connected to the upper end of the isolation cover and located above the feeding opening.

[0003] The existing dangerous solid waste crusher feeding opening anti-leakage device has poor anti-leakage effect. For example, in the high-efficiency dangerous waste blowing crusher (application number 202122397627.3), the rotating plate is not tightly sealed with the side wall and the bottom plate of the feeding hopper, and the feeding opening is always partially open during the rotation of the rotating plate, which affects the anti-leakage effect; in the crushing device for dangerous waste incineration treatment (application number 202222326338.9), the feeding opening is always in an open state, and the anti-leakage effect depends on the negative pressure condition of the dust suction port and other performances.
