A protective device for supersonic flame spraying

Abstract

The invention relates to a protection device for supersonic flame spraying, which includes a casing, on which are installed symmetrically distributed water curtain absorption devices for filtering waste gas, and on the casing is provided with a transmission belt mechanism for installing a spray gun; the water curtain The absorption device includes an absorption chamber, a semicircular unclosed long pipe connected to the shell and the absorption chamber, an outer cover connected with an exhaust fan, a water tank with a long strip hole on the absorption chamber and between the absorption chamber, and The water storage tank communicated with the absorption chamber; the transmission belt mechanism includes a roller and a belt installed on the roller. The belt is provided with a mounting hole, and the shell and the upper end of the belt are correspondingly provided with a strip-shaped through groove. The invention can protect the flame spraying process, isolate, absorb and purify the harmful gas and nano-dust generated during the spraying process, separate the operator from the high-temperature heat source, ensure the personal health of the operator, and drive the operator Motivation and increased productivity.

Description

technical field [0001] The invention relates to the technical field of spraying machinery, in particular to a protective device for supersonic flame spraying. Background technique [0002] Supersonic flame spraying is one of the technical means to metallurgically bond the coating of high-performance materials on the surface of workpieces. However, since the supersonic flame spraying process requires high-temperature combustion of fuel, it will produce certain harmful gases and nano-dust, which seriously threatens The health of the workers in the workshop leads to a bad working environment. At the same time, because the operator needs to work close to the equipment and directly contacts the high-temperature heat source, the physical load on the operator is heavy, which will reduce the work efficiency of the operator. Contents of the invention [0003] In order to avoid and solve the above-mentioned technical problems, the present invention proposes a protective device for s...
