High sealing performance sealing device with separate cylinder barrels

Abstract

The invention discloses a high sealing performance sealing device with separate cylinder barrels, which comprises an upper cylinder battle and a lower cylinder; the lower cylinder is of a cylindrical structure with openings in two ends and sleeves the outer side of the upper cylinder barrel; the upper cylinder barrel comprises a steam valve port located in the bottom and a discharging port located in the side part, an outside steam pipeline is connected to the steam valve port and is used for injecting high temperature high pressure steam into the upper cylinder barrel, the lower cylinder barrel is connected to the upper cylinder barrel in a sliding manner, when the lower cylinder barrel slides to the uppermost end, the lower cylinder barrel closes the discharging port, and the upper cylinder barrel is sealed; and a cylinder cover of a cover opening device covers the top end of the upper cylinder barrel. The structure of the cover opening device is innovatively deigned, the cylinder cover and a locking ring adopt a wedge-shaped tooth interlocking structure, and the sealing is reliable; and a bolt can be adjusted such that the in-place precision of the cover opening and closing actions are is ensured.

Description

technical field [0001] The invention belongs to the field of organic matter treatment, and in particular relates to a high-sealing performance sub-cylinder sealing device. Background technique [0002] The main bottleneck of the degassing and pressure relief speed of large container devices is the size of the degassing cross-sectional area. With the traditional degassing valve structure, increasing the caliber and increasing the opening speed are contradictory. Therefore, the pressure relief speed is generally slow and the processing efficiency is low. The problem. Although the cage-type ejection device increases the deflation caliber and pressure relief speed, it has a large load, complex structure, difficult packing, and no protection for the sealing part, low pressure relief efficiency, serious damage to the sealing ring, poor reliability and maintainability, etc. question. [0003] At present, the maximum effective cross-sectional area of ​​the conventional airtight co...

AI Technical Summary

Problems solved by technology

It is difficult to increase the effective cross-sectional area. Due to the limitation of the effective cross-sectional area of ​​the vent, it is also difficult to increase the pressure relief speed of the pressurization and pressure relief device, resulting in the failure of the organic matter treatment to achieve the ideal bursting effect.
