AI Technical Summary

Technical Problem

During the coking process in a coke oven, the relative movement between the guide sleeve of the flue gas duct and the cover causes the flue gas to escape, containing toxic substances that endanger health and accelerate equipment corrosion. Existing sealing devices are not airtight.

Method used

The system employs a cross-liquid sealing structure consisting of a first liquid tank and a sealing tank. It utilizes a liquid medium to fill mechanical gaps and form a stable liquid sealing interface. The design of the first liquid tank and the sealing tank ensures reliable sealing.

Benefits of technology

Significantly improves sealing reliability, reduces environmental pollution and equipment corrosion, lowers health risks, extends equipment lifespan, and simplifies manufacturing and maintenance costs.

Abstract

The utility model discloses a sealing device of a guide sleeve of a smoke guide vehicle and the smoke guide vehicle, and the sealing device of the guide sleeve of the smoke guide vehicle comprises a first liquid tank which is arranged at the bottom of an uncovering cover of the smoke guide vehicle, the opening of the first liquid tank faces upwards, and a liquid medium is arranged in the first liquid tank; the sealing groove is formed in the top end of the smoke guide vehicle guide sleeve, an opening of the sealing groove faces downwards and is opposite to the first liquid groove, and the cross section area of the opening of the sealing groove is smaller than that of the opening of the first liquid groove; when the uncovering lifting oil cylinder drives the uncovering cover to ascend, the sealing groove is embedded into the first liquid groove to form a first liquid sealing interface. According to the embodiment of the invention, the first liquid tank is additionally arranged at the lowermost part of the uncovering cover and the sealing groove is welded at the uppermost part of the guide sleeve, so that the first liquid sealing interface is formed when the first liquid tank and the sealing groove abut against each other, toxic flue gas is effectively prevented from escaping in the coal charging process, environmental pollution can be reduced, corrosion of acid gas to equipment can be reduced, and the service life of the equipment is prolonged.
