Gravity locking valve for dust collection of boiler

Abstract

The gravity blocking valve comprises a first valve body, a rotating shaft is fixedly connected to the position, close to the left side, of the interior of the first valve body, dust is received through the upper end of a valve head, and after the received dust is too much, due to the fact that the weight of the dust is larger than that of a heavy hammer, the gravity blocking valve is closed. The valve head is pressed downwards, the heavy hammer slides towards one side on the heavy hammer frame, the valve head is opened and inclines towards the interior of the first valve body, dust falls into the first valve body, after falling, the valve head is reset through the gravity of the heavy hammer so that the dust can be conveniently used next time, and meanwhile the air locking effect can be effectively achieved; and then the dust falls into the outer surface of the valve head on the second valve body at the lower end, so that the device can achieve the purposes of environmental protection and energy conservation by virtue of gravity driving without using external motor mechanical power while having a better air locking effect; and dust attached to the outer surface of the valve head can be effectively scraped, and the later use effect of the device is improved.

Description

technical field [0001] The invention relates to the field of air lock valves, in particular to a gravity air lock valve for boiler dust collection. Background technique [0002] The air lock valve is used in the pneumatic conveying system. For the positive pressure conveying system or the negative pressure conveying system, the air lock valve can evenly and continuously supply the material to the conveying pipe, so as to ensure that the gas and solid in the pneumatic conveying pipe are relatively stable, so that the pneumatic conveying can It works normally, and at the same time, it can cut off the upper and lower parts of the air lock valve. It acts as a gas lock. [0003] Most of the existing air lock valves are driven by electric or pneumatic means, and adopt an actuator in which the push rod and the crank are connected by living hinges, and the closing and opening of the valve head are positioned by adjusting the length of the push rod. Due to the error of the moving d...

AI Technical Summary

Problems solved by technology

Due to the error of the moving distance of the push rod and the deformation of the connecting rod of the valve head, air leakage and wear of the valve head are often caused by lax closing.

In addition, large pieces of foreign matter are often stuck in the flap valve, which will also cause damage to the connecting rod structure, and even cause the motor to burn out or the reducer to fail and deform.
