A double self-locking dust discharge and air lock device for the bottom of the dust collector

Abstract

The invention relates to a dual-self-locking-type dust discharging and air locking device for the bottom of a dust collector. The dual-self-locking-type dust discharging and air locking device for the bottom of the dust collector comprises a shell with a feed inlet and a discharge outlet which are respectively formed in an upper end and a lower end, counterweights are arranged on a left upper valve plate, a right upper valve plate, a left lower valve plate and a right lower valve plate to form a lever structure to seal a feed air pipe and a discharge air pipe, and the left upper valve plate, the left lower valve plate, the right upper valve plate and the right lower valve plate realize restoration from a sealed state of the feed air pipe and the discharge air pipe respectively through a left restoring spring and a right restoring spring. Since the feed air pipe and the discharge air pipe are arranged and the internal parts are sealed through baffles, the sealing can be realized and external air can be prevented from entering the dust collector through the valve plates which are installed at the bottoms of the feed air pipe and the discharge air pipe; the dust also plays roles of sealing and air locking; since self-locking springs are arranged, the valve plates can be guaranteed to be restored in time and the sealing effect is enhanced.

Description

technical field [0001] The invention relates to an ash discharge device utilizing a material seal, in particular to a double self-locking ash discharge and air lock device used at the bottom of a dust collector. Background technique [0002] At present, the bottom of the dust collector on the market generally adopts single flash valve, double flash valve and rotary valve. The rotary valve has a good wind locking effect, but its structure is complicated. The structure of the single flashing valve is simple, but there is only one valve at the back. During the dust discharge process, the external wind energy enters the inside of the dust collector, which affects the dust collection effect. Double flash valve is equivalent to single flash valve because there is no interlock device between the two valves. Therefore, there is a need for a dust-discharging and air-locking device with a relatively simple structure and good air-locking effect. Contents of the invention [0003] ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the external wind energy enters the dust collector and affects the dust collection effect during the dust discharge process of the existing ash discharge device, and provides a double self-locking ash discharge lock for the bottom of the dust collector Wind device, the present invention is provided with feeding air duct and unloading air duct, and its interior is sealed by a partition plate, and the valve plate installed at the bottom of the feeding air duct and the unloading air duct can be sealed to isolate the external wind energy from entering the dust collector Inside, there is also a counterweight to ensure that the upper valve plate and the lower valve plate will only be opened when the amount of dust in the feeding air duct and the lower material air duct reaches a certain amount, and the amount of dust also plays a role in sealing and locking the air. Function, the set counterweight can be set inside the shell or outside the shell. When it is set outside the shell, it is convenient to observe the internal dust discharge. At the same time, two self-locking springs are set to ensure the timely reset of the valve plate and strengthen the sealing effect
