Semi-automatic unloading apparatus for gas chamber

Abstract

The invention provides a semi-automatic gas-holder emptying device which prevents the lighting strike for the operator when the gas-hole is lifted suddenly and the operator is climbed to the top of the gas-holder and prevents the fire from spreading to the interior of the gas-holder when the top part of the gas-holder catches fire. The semi-automatic gas-holder emptying device comprises a gas-holder first tower, a gas-holder second tower and a main emptying valve; the main emptying valve is mounted on a main emptying pipe; the main emptying pipe is welded on the top plate of the gas-holder; the main emptying pipe is connected with at least two branch emptying pipes through flanges; a pneumatic valve with an air pipe is mounted on the flange connection position of the main emptying pipe and one branch emptying pipe; a manual emptying valve is mounted on the flange connection position of the main emptying pipe and the other branch emptying pipe. The technical proposal is adopted to enable the semi-automatic gas-holder emptying device to have the advantages that: 1. the operator is not allowed to climbed to the top part of the gas-hole when the lightning occurs so that the lightning strike accident is avoided; 2. the height control of the gas-holder is rapid so that the extraordinarily serious device accident that the gas-holder bursts out from the gas-holder flume is avoided.

Description

Technical field: [0001] The invention relates to the technical field of gas supporting equipment, and refers to a semi-automatic venting device used on a gas cabinet. Background technique: [0002] In the prior art, the gas produced by the gas furnace enters the gas inlet valve of the gas holder from the outlet of the float valve, and then enters the gas holder through the gas holder inlet pipe. Due to the force of the pressure gas acting on the top of the gas holder, the gas holder first Spiral up along the guide rail of the first tower of the gas cabinet, when the first tower of the gas cabinet rises to a certain point, the hook of the gas cabinet fixed on the first tower of the gas cabinet hangs on the second tower of the gas cabinet, so that the second tower of the gas cabinet rises along the guide rail of the second tower of the gas cabinet , when rising to the limit height, if the air intake of the gas holder is greater than the outlet air, the gas holder will fly out ...

AI Technical Summary

Problems solved by technology

However, when there is a sudden power failure or equipment accident in many gas-consuming departments at the same time, the time from the original height of the gas cabinet to the time when the gas cabinet flies out of the gas cabinet slot is very short, and the operator cannot go to the top of the gas cabinet to open the vent valve in time. When it is raining or thundering, if the operator goes to the top of the gas tank, it is very easy to cause a lightning strike accident
