Description

Storage bin pressure relief respirator

Technical Field

The utility model relates to a respirator technical field specifically is a feed bin pressure release respirator.

Background

Powder storage storehouse is when carrying the powder to enter into, owing to use the gas transport powder to get into, atmospheric pressure in the feed bin can be along with the gas and the powder grow that constantly get into, consequently, need use the relief valve to install the filter core in the relief valve simultaneously, when avoiding the pressure release, gas carries the dust and together leaks. But after long-time the use, the filter core piles up the one deck powder outward, can influence the pressure release effect, and what prior art adopted is installation vibrating motor, and the vibration makes the outer powder of filter core drop for the relief valve, and this kind of design defect lies in long-time the back of using, and a great deal of bolt in the relief valve can become flexible, leads to that the relief valve is not hard up or inside filter core is not hard up, and then influences the pressure release effect.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a feed bin pressure release respirator has solved the problem that current relief valve easily becomes flexible when the pressure release influences the pressure release effect.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: a bin pressure relief respirator comprises a filter cylinder arranged on a bin, wherein a shell is arranged above the filter cylinder, the shell is divided into an upper chamber and a lower chamber by a partition plate, the lower chamber is communicated with the filter cylinder, and an exhaust port communicated with the lower chamber is formed in the outer side of the shell;

an air inlet nozzle is arranged on one side above the shell, an air hole is arranged in the middle of the upper part of the shell, an electromagnetic valve is arranged on the air hole, the bottom of solenoid valve is connected with the gas injection pipeline, just the gas injection pipeline runs through the baffle and inserts to the lower chamber in.

Preferably, the shell is connected with the filter cylinder through a hoop, and a sealing ring is arranged in the hoop.

Advantageous effects

The utility model provides a feed bin pressure release respirator. The method has the following beneficial effects: this feed bin pressure release respirator strikes the mode of powder on the filter core through the pulse that adopts strong air current, can high-efficiently quick blow off the powder that piles up on the filter core to owing to adopt the air current impact formula, can avoid leading to the not hard up of relief valve or filter core because of adopting motor vibration. The blown gas can be discharged along with the gas in the storage bin, other substances cannot be generated, and the device is safe, efficient and environment-friendly.

Drawings

FIG. 1 is a schematic view of the present invention;

fig. 2 is a cross-sectional view of fig. 1 of the present invention.

In the figure: 1. the air injection device comprises an electromagnetic valve, 2, a shell, 3, an air outlet, 4, a filter cartridge, 5, an air inlet nozzle, 6, a clamp, 7, an air injection pipeline, 8, a partition plate, 9, a lower chamber, 10, a sealing ring, 11, an upper chamber, 12 and an air hole.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The following working principles, detailed connecting means thereof, and the following main descriptions of the working principles and processes are well known in the art, and will be referred to by those skilled in the art for the specific connection and operation sequence of the components in this application.

The utility model provides a technical scheme:

as can be seen from fig. 1-2, a silo pressure relief respirator of the present disclosure includes a filter cartridge 4 mounted to a silo; when atmospheric pressure in the feed bin is too big, the inside gas of feed bin discharges through cartridge filter 4, and the filter core inside cartridge filter 4 filters down along with gas spun powder.

The top of cartridge filter 4 is equipped with casing 2, and casing 2 passes through clamp 6 and links to each other with cartridge filter 4, is provided with sealing washer 10 in the clamp 6.

The shell 2 is internally divided into an upper chamber 11 and a lower chamber 9 by a partition plate 8; an air inlet nozzle 5 is arranged on one side above the shell 2;

the upper chamber 11 is a high-pressure gas storage chamber, and gas is conveyed into the upper chamber 11 through the gas inlet nozzle 5.

An air hole 12 is formed in the middle of the upper portion of the shell 2, the electromagnetic valve 1 is mounted on the air hole 12, an air injection pipeline 7 is connected to the bottom of the electromagnetic valve 1, and the air injection pipeline 7 penetrates through the partition plate 8 and is inserted into the lower chamber 9;

the solenoid valve 1 is connected with the air hole 12 and the air injection pipeline 7. The solenoid valve 1 is closed after a short opening. When opening, the high-pressure gas in the upper chamber 11 enters into in the jet-propelled pipeline 7 through gas pocket 12 to on spraying the filter core in the cartridge filter 4 by jet-propelled pipeline 7, through the high-pressure gas effect that erupts on the filter core, spout the powder that piles up on the filter core and fall, the powder falls back to the feed bin in again, and the gas of spun gas follow feed bin pressure release together discharges through gas vent 3.

The lower chamber 9 is communicated with the filter cartridge 4, and the outer side of the shell 2 is provided with an exhaust port 3 communicated with the lower chamber 9;

when gas pressure relief in the feed bin, the gas enters the inner side of the filter element through the outer side of the filter element, then flows into the lower cavity 9, is discharged through the exhaust port 3, and is separated through the filter element to remove powder carried in the gas.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
