Description

Endoscopic camera protection device for furnace body

Technical Field

The utility model relates to the technical field of copper electrolysis, in particular to a furnace body endoscopic camera protection device.

Background

In the smelting of copper concentrates, there is a process in which an Ausmelt furnace is used for smelting. The fireproof brick is a cylinder with the diameter of 4-6 meters and made of a special steel plate with the diameter of 40mm, the height of the cylinder is generally 15-19 meters, and a fireproof brick with the thickness of 400mm is built on the inner wall of the cylinder. The top is sealed by a cover plate, a 500 multiplied by 500mm charging hole is reserved, the bottom is sealed by brickwork, and a discharging hole with the diameter of 100mm is arranged on the side edge of the bottom. Typically a production campaign exceeds one year. During the production process, the refractory bricks can collapse due to coking impact, uneven heating and the like. The collapse condition of refractory bricks in the furnace is often required to be checked in the production process. The direct observation range from the feed inlet is limited, and a camera needs to be extended into the furnace from the positions of the feed inlet and the like for endoscope observation. However, the furnace is filled with smoke with the temperature of over 1000 ℃ during production, and the camera is easily burnt out.

Disclosure of Invention

The utility model aims at solving the problem that the inside of the furnace is full of high-temperature flue gas exceeding 1000 ℃ during production, and the camera is very easy to burn out, and providing a protective device for the endoscopic camera of the furnace body.

The utility model has the following concrete scheme: a camera protection device for furnace body endoscope comprises an inner tube, wherein the front end inside the inner tube is used for mounting a camera, high-temperature-resistant glass is mounted at the front end of the inner tube, a connecting line of the camera extends out of the rear end of the inner tube, an intermediate tube is sleeved outside the inner tube, one end of the intermediate tube is closed, an opening is formed in the other end of the intermediate tube, an outer tube is sleeved outside the intermediate tube, two ends of the outer tube are closed, support frames are arranged between the inner tube and the intermediate tube and between the intermediate tube and the outer tube, the inner cavity of the intermediate tube is communicated with the inner cavity of the outer tube through the opening, branch tubes communicated with the inner cavity are respectively arranged on the side walls of.

Inner tube, intervalve and outer tube constitute by two sections pipe connection, are equipped with certain contained angle between two sections pipelines, the camera is installed in the front end pipeline in two sections pipelines.

The contained angle is 90 ~ 120.

Front end pipeline length is 200~400 cm.

The working principle of the utility model is as follows: through injecting cooling water into from two spinal branch pipes to intermediate tube and outer tube, play the effect of continuous cooling to the camera, the camera passes through the data line with the picture of shooing and outwards exports, can guarantee that the camera is not burnt out by high temperature, realizes observing the firebrick that can cover on a large scale in the stove through rotatory inner tube and the length of control stretching into in the stove.

The utility model discloses following beneficial effect has: simple structure, convenient operation has solved better that the environment is abominable in the present Ausmelt stove, is full of the high temperature flue gas, can't directly peep the problem with the camera, has realized that the ordinary camera of high temperature furnace peeps in.
