Description

Technical Field

[0001] The utility model relates to the technical field of leather deodorization, in particular to a high-efficiency leather deodorization machine. Background Art

[0002] As people's living standards gradually improve, the requirements for leather are getting higher and higher. A large amount of chemicals are used in the process of coating, finishing, embossing and compounding of leather, which will cause a lot of pungent odors in the composite leather.

[0003] The traditional method of deodorization is to store the leather in an open warehouse for natural volatilization, which takes a long time. There is also a method of using natural wind blowing. Although the efficiency has been improved, the time is still relatively long. Only after high-temperature blowing can the odor evaporate quickly. The current deodorizers basically use a high-temperature blowing and deodorization process in one, that is, the leather surface is blown at high temperature in the same oven, and the toxic gas is discharged from the oven through an air suction fan. Since the high-temperature blowing and suction are in the same box, this deodorization process has the problem of incomplete deodorization, and the residual toxic gas in the leather is at least more than 5%. At the same time, there are problems such as large heat loss and low thermal efficiency. For this reason, there is a public technology on the market that proposes a new leather deodorizer, including a reeling machine, a jointing machine is provided on the left side of the reeling machine, and a cloth stopping device is provided on the right side of the jointing machine near the top edge. This technology heats the leather with a burner to volatilize and emit toxic gases;

[0004] However, the burner used in the above technology always has the safety hazard of incomplete combustion when burning indoors, and the odorous gas generated after heating is directly sucked away and discharged by the strong suction fan, which does not solve the problem of large heat loss. Therefore, it is necessary to optimize and improve the structure of the high-efficiency leather deodorizing machine. Utility Model Content
