Description
Technical field
It is defeated that the utility model belongs to the powder used in catalyst manufacture field, more particularly to a kind of catalyst manufacturing procedures
Send the gas-tight sealing of the Anti-powder-leakage of push rod.
Background technology
Due to the requirement of the performance of catalyst, it is possible to which contacting that the equipment of powder can not all etc. be had using oil sealing, water seal can
The liquid substance of catalyst can be polluted, the dry envelope of the seal that can only be taken, because the powder diameter used in catalyst is small, merely
With sealing ring it is difficult to be sealed.
For example, a kind of push rod for transporting powder, push rod is sealed with sealing ring, because push rod is in constantly during production
In motion, powder constantly can be spilt from gap in filler bin, pollute environment, and add production loss, and may be to outside
Push-rod electric machine cause potential potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of air seal set of anti-powder leakage, solves one in above-mentioned technical problem
It is individual or multiple.
The utility model provides a kind of air seal set of anti-powder leakage, including discharge nozzle and coordinating with discharge nozzle is set
The charging ram put, discharge nozzle one end sets discharging opening, and the discharge nozzle other end is provided with pusher mouthful, and charging ram is plugged in pusher mouthful, goes out
Expects pipe is provided with charging aperture, and the height of charging aperture is higher than the height of discharging opening, first is additionally provided between charging ram and discharge nozzle close
Envelope portion and the second sealing, discharge nozzle are provided with malleation mouthful, and malleation mouthful is located at going out between the first sealing and the second sealing
Expects pipe tube wall.
A kind of air seal set for anti-powder leakage that the utility model is provided, when charging ram is pulled outwardly, powder is through discharging opening
Into in discharge nozzle, when charging ram is pushed away inward, powder is released into forward discharging opening.Charging ram and discharge nozzle pipe of the present utility model
The tube wall in the middle of two seals, two seals is used to be passed through compressed air formation malleation between wall, prevent powder spills discharging
The effect of pipe is notable.
The utility model is usually used in the sealing device of the feed device of bin bottom, in the case where not influenceing equipment to run
Effectively prevent the situation of leakage powder, improve work situation, it is therefore prevented that dust reduces wave to the potential danger of external motor
Take.
In some embodiments, the first sealing and the second sealing that the utility model is skipped are sealing ring, two
Sealing ring is arranged charging ram.
In some embodiments, charging ram is fastened with vibrator.
Vibrator is provided, the congestion problems of powder in discharge nozzle are further eliminated.
Brief description of the drawings
A kind of a kind of structural representation of the air seal set of the anti-powder leakage for embodiment that Fig. 1 provides for the utility model
Figure.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model provides a kind of air seal set of anti-powder leakage, including discharge nozzle 1 and with
The charging ram 2 that discharge nozzle 1 is equipped with, one end of discharge nozzle 1 sets discharging opening 3, and the other end of discharge nozzle 1 is provided with pusher mouthful 4, pusher
Bar 2 is plugged in pusher mouthfuls 4, and discharge nozzle 1 is provided with charging aperture 5, and the height of charging aperture 5 is higher than the height of discharging opening 3, charging ram 2 with
The first sealing 6 and the second sealing 7 are additionally provided between discharge nozzle 1, discharge nozzle 1 is provided with malleation mouthful 8, and malleation mouthful 8 is located at
The tube wall of discharge nozzle 1 between first sealing 6 and the second sealing 7.
A kind of air seal set for anti-powder leakage that the utility model is provided, when charging ram 2 is pulled outwardly, powder is through discharging opening
3 enter in discharge nozzle 1, and when charging ram 2 is pushed away inward, powder is released forward to discharging opening 3.Charging ram 2 of the present utility model and go out
Use the tube wall in the middle of two seals, two seals to be passed through compressed air formation malleation between the tube wall of expects pipe 1, prevent the leakage of powder
The effect for going out discharge nozzle 1 is notable.
The utility model is usually used in the sealing device of the feed device of bin bottom, in the case where not influenceing equipment to run
Effectively prevent the situation of leakage powder, improve work situation, it is therefore prevented that dust reduces wave to the potential danger of external motor
Take.
Preferably, the first sealing 6 and the second sealing 7 that the utility model is skipped are sealing ring, two sealing rings
It is arranged charging ram 2.
Further, charging ram 2 is fastened with vibrator there is provided vibrator, eliminates the congestion problems of powder in discharge nozzle 1,
Sex work of having a rest is better.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these belong to this practicality
New protection domain.
