Protecting device for high velocity oxygen fuel

Abstract

The invention relates to a protecting device for high velocity oxygen fuel. The protecting device comprises a shell body. The shell body is provided with symmetrically-distributed water curtain absorbing devices used for filtering waste gas. The shell body is provided with a transmission belt mechanism used for installing a spraying gun. Each water curtain absorbing device comprises an absorbing room, long pipes, an outer cover, a water box and a water storing box, wherein each long pipe communicates with the shell body and the absorbing room and is half-round and no-closed, the outer cover is connected with an exhaust fan, the water box is located on the absorbing room, a long hole is formed between the water box and the absorbing room, and the water storing box communicates with the absorbing room. The transmission belt mechanism comprises rolling wheels and a belt installed on the rolling wheels. Installing holes are formed in the belt. A strip-shaped through groove is formed in the position, corresponding to the upper end of the belt, of the shell body. By means of the protecting device for high velocity oxygen fuel, protection to a flame spraying process can be achieved, isolating and absorbing purifying effects on noxious gas and nano-duct produced in the flame spraying process are achieved, an operator can be separated from a high temperature heat source, the health of the operator is ensured, the enthusiasm of the operator is motivated, and the working efficiency is improved.

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 for metallurgical bonding coating high-performance materials on the surface of workpieces. However, because the supersonic flame spraying process requires high-temperature combustion of fuel, certain harmful gases and nano-dust will be produced, 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 sup...
