Large single-stage rubber diaphragm-sealed accumulator unit

Abstract

The invention discloses a large single-stage rubber diaphragm-sealed accumulator unit. The accumulator unit comprises a cabinet body, a piston and a seal diaphragm for sealing the cabinet body and the piston, wherein the cabinet body comprises an upright post, a side plate, a top cabinet plate and a bottom cabinet plate which form a cylindrical shell; the piston which can rise and fall freely is arranged in the cabinet body, the rubber seal diaphragm is arranged between the outer side of the piston and a side cabinet plate, the lower edge of the rubber seal diaphragm is connected with the lower part of the piston, and the upper edge is fixed to the inner wall of the side cabinet plate to form the single-stage sealed accumulator unit; and the side cabinet plate, the rubber seal diaphragm, the piston and the bottom cabinet plate form a sealed barrel, and the piston drives the rubber seal diaphragm to move up and down in the cabinet body to store and release coal gas. By using the accumulator unit, the compressor can run stably and reliably and can provide the coal gas for users in the more stable pressure.

Description

technical field [0001] The invention relates to a gas storage cabinet, in particular to a large single-section rubber membrane-sealed gas storage device used in the metallurgical industry. Background technique [0002] Due to the large capacity of the two-stage sealed gas storage, the rubber membrane-sealed gas cabinets currently used in the metallurgical industry in China are mainly two-stage sealed structures, and their maximum capacity can reach 150,000m 3 or larger. The two-stage seal also has two gas storage pressures, that is, one pressure when the piston rises, and one pressure when the piston drives the T-shaped baffle to rise, which makes the pressure of the gas tank unstable, resulting in the operation of the subsequent pressurizer. Instability of user parameters. In addition, when the gas storage capacity reaches the upper half of the two-stage rubber membrane sealed gas cabinet, the piston drives the T-shaped baffle to move up and down; when the gas storage cap...

AI Technical Summary

Problems solved by technology

The two-stage seal also has two gas storage pressures, that is, one pressure when the piston rises, and one pressure when the piston drives the T-shaped baffle to rise, which makes the pressure of the gas tank unstable, resulting in the operation of the subsequent pressurizer. Instability of user parameters

In addition, when the gas storage capacity reaches the upper half of the two-stage rubber membrane sealed gas cabinet, the piston drives the T-shaped baffle to move up and down; when the gas storage capacity reaches the lower half, the T baffle falls on the lower bracket , the piston drives the T-shaped baffle to run up and down by its top impact head, so the T-shaped baffle will inevitably shift or rotate after repeated operations, which will bring troubles to the safe operation and maintenance of the gas cabinet

In view of the fact that the existing gas storage device is difficult to meet the requirements of metallurgical users with large gas storage capacity, stable gas storage pressure, simple operation and use, and small maintenance, the present invention proposes a large-capacity single-stage rubber-membrane-sealed gas storage device
