Description

Improved generation airlock valve

Technical Field

The utility model relates to conveying blanking field especially involves lock blast gate technical field, specifically indicates an improved generation lock blast gate.

Background

Because of the environmental protection requirement, many production lines have a lot of bags to gather dust, and the dust collector hopper unloading just has the lock wind problem, adopts gyration unloading lock wind valve most in the early stage, and later stage has the flap valve that uses gradually, but all has a lot of problems in the use. The rotary blanking air locking valve has higher power consumption, a gap is formed between the blade and the shell, air leakage is more, the blade is seriously abraded in the later period, the dust collection efficiency of a cyclone cylinder of a bag dust collection and grinding system is reduced, and the energy consumption is increased; the sealing performance is poor, the abrasion later stage is particularly serious, and the operation rate is influenced because the blocky materials are easy to block. Though the flap valve is used in the position, the problem of power consumption is solved, air leakage is serious, abrasion is serious, and maintenance cost is high.

Chinese utility model patent that application number is 201821301050.3 has just announced an unpowered lock wind valve, but the lock air curtain formula as an organic whole of this kind of lock wind valve, because when the unloading, lock air curtain bottom wearing and tearing are serious, when the lock air curtain needs to be changed, need lock the whole pulling down of air curtain, and need whole scrapping, the material waste is serious.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to prior art's not enough, provide an improved generation lock blast gate, when making the convenient dismantlement of lock wind curtain, reduce scrapping of material.

The utility model discloses a following technical scheme realizes, an improved generation lock blast gate, including locking the air curtain, lock the air curtain including articulating the last valve on the valve body to and articulate the lower valve on last valve, lock the accent adaptation of air curtain and valve body.

The utility model discloses when using, when the unloading, the material strikes valve down, and lower valve wearing and tearing are to the certain degree when, will descend valve from the last valve to pull down, then change new lower valve, the utility model discloses only change lower valve, when convenient the dismantlement, scrap of reduce material.

Preferably, a reinforcing plate is arranged on the side face, in contact with the material, of the lower valve.

This preferred scheme passes through the setting of reinforcing plate, and the valve's degree of wear-resisting under the reinforcing of being convenient for, the life of valve under the reinforcing, the reinforcing plate also plays certain counter weight effect simultaneously.

Preferably, the valve body is in threaded connection with a jackscrew, the jackscrew is in threaded connection with a pressing plate located in the valve body, and the lower valve body is located between the pressing plate and the valve body cavity opening.

This preferred scheme is through the length of jackscrew screw in valve body, adjusts the distance between pressing plate and the lower valve plate, and the aperture size of restriction raft guarantees the lock wind effect, when unloading volume is very big, increases the interval between valve plate and the lead screw to the aperture of increase raft guarantees the lock wind effect, vice versa.

Preferably, the upper valve body is hinged to the lower valve body through a hinge, and the hinge is located on the side face, far away from the material, of the upper valve body.

This preferred scheme passes through the setting of hinge, and the convenient articulated of valve body and last valve body down obtains the hinge repeatedly usable easily simultaneously.

Preferably, the valve body is further provided with air inlet pipes located on two sides of the hinge, the air inlet pipes are located above the hinge and extend obliquely to the hinge, the air inlet pipes are further provided with valves, and the air inlet pipes extend into the valve body in a sealing mode.

This preferred scheme is when using because can produce the negative pressure in the valve body, consequently in the outside air can follow the intake pipe and enter into the valve body, blasts the dust on the hinge, avoids the dust to pile up, influences the normal use of hinge.

Preferably, a fixed connection plate is fixedly connected to the valve body, and the jackscrew is in threaded connection with the fixed connection plate.

This preferred scheme plays the effect that supports the jackscrew through the setting of solid fishplate bar.

The utility model has the advantages that: when the material is discharged, the material impacts the lower valve, and when the lower valve is abraded to a certain degree, the lower valve is detached from the upper valve and then replaced with a new lower valve, so that the lower valve is replaced, the material scrapping is reduced while the lower valve is convenient to detach; the arrangement of the reinforcing plate is convenient for enhancing the abrasion resistance of the lower valve and prolonging the service life of the lower valve; through the setting of hinge, the convenient articulated of valve body and last valve body down, the hinge obtains repeatedly usable easily simultaneously.
