Inflatable type thin oil sealing gas tank

Abstract

The invention relates to an inflatable type thin oil sealing gas tank. The inflatable type thin oil sealing gas tank comprises a tank body and a sealing device, wherein the sealing device comprises an inflatable sealing mechanism and an oil sealing mechanism; the inflatable sealing mechanism comprises an inflatable ring and a draught fan; a piston ring beam is provided with an upper guard plate and a lower guard plate; the inflatable ring is located among a side board, the piston ring beam, the upper guard plate and the lower guard plate; the draught fan is arranged on a piston frame; the inflatable ring is connected with the draught fan through an inflatable pipe; the inflatable ring can be tightly sealed with the side board and the piston ring beam after being supplemented with certain pressure; the oil sealing mechanism comprises a piston oil groove, a bottom oil groove, an oil pump station and a high-level oil tank; the piston oil groove is formed by the side board, the inflatable ring and the piston ring beam and filled with sealing oil of a certain height; the bottom oil groove is arranged at the bottom inside the tank body and communicates with the oil pump station outside the tank body; the oil pump station is connected with the high-level oil tank on the upper portion of the outer wall of the side board through a pump and an oil ascending pipe; and an outlet of the high-level oil tank is formed in the inner wall of the side board. The gas tank can compensate for mounting errors and control the sealing effect.

Description

technical field [0001] The invention belongs to the field of gas cabinets, in particular to an inflatable thin oil sealed gas cabinet. Background technique [0002] Dry-type gas holders are widely used in the recovery and storage of by-product gas in iron and steel enterprises. The dry-type gas holders that are widely used in my country mainly include polygonal thin oil-sealed gas holders, circular thin-oil-sealed gas holders and rubber membrane-sealed dry-type gas holders. There are also circular dry oil sealed gas holders that are less used. The polygonal thin oil sealed gas holder adopts thin oil plus spring steel slide plate seal, the round thin oil sealed gas cabinet adopts thin oil plus weight hammer rubber seal, and the rubber membrane sealed dry gas holder adopts rubber membrane plus bolt compression Sealed, round dry oil-sealed gas holders are grease-weighted hammer rubber seals.

Problems solved by technology

[0003] For various traditional sealing devices, each has certain defects: (1) The steel slide plate and spring used in the polygonal thin oil sealed gas cabinet have a poor sealing effect, especially at the corners of the polygon. Gas escape phenomenon, and the steel slide plate and spring are set in the oil groove, it is impossible to observe the sealing device conveniently, and the production, installation and operation costs of the oil circulation system are high; (2) The thin oil used in the circular thin oil sealed gas cabinet The rubber seal of the weighted hammer has a good sealing effect, but it is very expensive, reaching 11,000 yuan / m, and the diameter of the gas cabinet of this cabinet type is generally large. For a common 200,000 cabinet, the cost of this part alone reaches two At the same time, it is necessary to adopt a high-cost oil circulation system. The heavy hammer rubber has high requirements for the installation quality of the side plate. The strain adjustment ability of hammer rubber is insufficient, and it can only compensate for small side plate deformation, and its compensation ability cannot be controlled and quantified; (3) The sealing effect of the rubber membrane and bolt compression seal used in the rubber membrane seal dry gas tank is relatively low. Good, but its key equipment—the rubber membrane is expensive, and its sealing form is not a reliable seal in principle; (4) The grease-weighted hammer rubber seal used in the round dry oil-sealed gas cabinet has an average sealing effect , and the pressing force of the sealing device on the side plate is too large, which may easily cause deformation of the side plate and further cause the risk of gas leakage. In addition, the sealing device needs to add non-recyclable lubricating grease regularly, and the cost is high; The installation quality of the side plate is very high. Once the installation is not up to standard, there will be a large amount of local oil leakage, and even the gas can not be sealed. The strain adjustment ability of the heavy hammer rubber is insufficient, so it can only compensate for small deformation of the side plate. And its compensation ability cannot be controlled and quantified
