Problems solved by technology

[0005] During the use of the existing air locker, the material often enters the gap between the blade and the air locker shell through the drive of the blades. After being squeezed tightly, it is easy to cause blockage, damage to the air locker blades, and affect normal production. Due to the problems of delaying a lot of production time and low work efficiency, this application proposes an air locker with anti-blocking function. The air locker has the function of automatically adjusting the gap between the blades and the air locker shell during use. , it can automatically adjust when there is a blockage between the blade and the air locker shell, which will not cause damage to the blades of the air locker, and will not delay a lot of time for equipment maintenance, and the work efficiency is high

Embodiment 1

[0031] refer to Figure 1-3 , the present invention provides a positive pressure air lock with anti-blocking function, including the air lock housing 2, the feed port 6 and the discharge port 1 connected to the air lock housing 2, and the air lock housing The rotating shaft 9 inside the housing 2, the blades 10 connected to the rotating shaft 9, and the driving mechanism 13 that drives the rotating shaft 9 to rotate. There are multiple arc-shaped activities connected between the inside of the housing 2 and the blades 10 through the telescopic mechanism 3. The plate 4 and a plurality of arc-shaped movable plates 4 cooperate with each other to form the inner cavity of the air lock, and the arc-shaped movable plate 4 is connected with a pressure sensor electrically connected with the telescopic mechanism 3 .

[0032] Working principle: When using the positive pressure air lock with anti-blocking function in this application, the material is put into the trough formed by the blade...

Embodiment 2

[0035] refer to Figure 1-3 , based on Embodiment 1, in this embodiment, one end of the vane 10 close to the interior of the air lock housing 2 is connected with an elastic rubber 7 , and the elastic rubber is bonded to the vane 10 by an adhesive.

[0036] By connecting the elastic rubber 7 at one end of the blade 10, when materials are clamped between the elastic rubber 7 and the arc-shaped movable plate 4 to form pressure, the generated pressure first presses the elastic rubber 7, and the elastic rubber 7 plays a role. The function of cushioning, the elastic function of the elastic rubber 7 can also increase the distance between the arc-shaped movable plate 4 and the elastic rubber 7 when compressed, further preventing the blockage caused by the material, and has a certain effect on the blade 10 of the air lock. The protection function reduces the possibility of damage to the blade 10 and further reduces the maintenance cost of the blade 10 . Wherein the shortest distance b...

Embodiment 3

[0038] refer to Figure 1-3 , based on Embodiment 1, a plurality of arc-shaped movable plates 4 in this embodiment are provided with sealing assemblies between adjacent ones.

[0039] Since the arc-shaped movable plate 4 is spliced ​​inside the air locker shell by multiple splicing, there may be a certain gap between the arc-shaped movable plates 4, if the material enters between the movable plate and the air locker shell through the gap, If the long-term accumulation is too much, the telescopic mechanism 3 will also have difficulties in the process of driving the arc-shaped movable plate 4 to move. Therefore, this application further provides a sealing assembly between adjacent contacting movable plates, which can be avoided by installing the sealing assembly. The material enters between the arc-shaped movable plate 4 and the housing of the air lock, causing difficulty in preventing blockage.

Abstract

The invention relates to a positive-pressure air sealing device with an anti-blocking function. The positive-pressure air sealing device with the anti-blocking function comprises an air sealing deviceshell body, a charge port and a discharge port which are connected to the air sealing device shell body, a rotary shaft connected into the air sealing device shell body, blades connected to the rotary shaft, and a drive mechanism driving the rotary shaft to rotate, wherein a plurality of arc-shaped movable plates are connected between the interior of the air sealing device shell body and the blades through telescopic mechanisms; the plurality of arc-shaped movable plates are mutually spliced in a matching manner to form an inner cavity of the air sealing device; and a pressure sensor electrically connected with the corresponding telescopic mechanism is connected to each arc-shaped movable plate. The air sealing device has a function of automatically adjusting gaps between the blades and an air sealing device housing in a use process, that is, the air sealing device is capable of automatically adjusting in the case of blocking between the blades and the air sealing device housing, damage to the blades of the air sealing device is avoided, lots of time for equipment maintenance is avoided, and high working efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of air locks, in particular to a positive pressure air lock with an anti-blocking function. Background technique [0002] The air shutoff device is an important device in the pneumatic conveying and ventilation dust removal network. Its main function is to continuously and timely discharge the materials in the unloader or dust collector, and at the same time prevent the outside air from entering the unloader or dust collector. The device is widely used in the pneumatic transportation of equipment in rice milling, flour milling, feed, machinery and chemical industry, medicine, tobacco, metallurgy, cement and dust removal, and the discharge of pipe network pressure. Powdery, granular, flaky and fibrous materials play the role of continuous discharge. [0003] The existing air locker is usually composed of a rotating shaft, a driving mechanism for driving the rotating shaft to rotate, blades connected to the r...
