Detailed Description

The technical solution of the present invention will be described below with reference to the accompanying drawings and examples.

As shown in fig. 1 to 4, an electrostatic precipitator is with letting out explode device, including base 1, the door body 3, gland 4, clamping ring 5, lead screw 6, spring 7, interface nipple joint 8 and eyebolt 9, interface nipple joint 8's first end fixed connection is on electrostatic precipitator's electric field top cap, base 1 is fixed in interface nipple joint 8's second end, clamping ring 5 is fixed in on base 1 through fastener 10, be fixed with a plurality of lead screw 6 that even interval set up on clamping ring 5, door body 3 is located in clamping ring 5, be equipped with the guide block 11 that sets up with the cooperation of a plurality of lead screw 6 on the door body 3, and guide block 11 overlaps in lead screw 6 lower part, gland 4 is fixed in lead screw 6's upper portion, and be equipped with spring 7 between gland 4 and the guide block 11, be fixed with eyebolt 9 on gland 4. The above structure constitutes the basic structure of the utility model.

In this embodiment, a sealing gasket 2 is arranged between the door body 3 and the base 1, and the sealing gasket 2 is fixed on the base 1 through a pressing ring 5. In the initial state, the door body 3 and the base 1 are sealed to play a role of air leakage prevention.

In this embodiment, base 1 and clamping ring 5 adopt the setting of ring structure, and are equipped with a plurality of screw holes that set up with fastener 10 cooperation on base 1 and the clamping ring 5 respectively. The base 1 and the compression ring 5 are fixedly connected through the fastener 10.
