Abstract

The invention discloses a high-temperature smoke exhaust fan, which solves the problems that in the prior art, due to environments of high temperature, thick smoke and the like, the service life of the fan is shortened, or even safety accidents can be caused. The high-temperature smoke exhaust fan disclosed by the invention comprises a fan case, wherein a protection layer coats the inner wall of the fan case and is formed by spraying protection paint; the protection paint is prepared from the following raw materials in parts by weight: 70 to 95 parts of high-temperature-resistant resin, 10 to15 parts of nanometer graphene, 5 to 10 parts of nanometer carbon tubes, 5 to 10 parts of polytetrafluoroethylene, 0.1 to 1 part of asbestos fiber, 0.1 to 1 part of lanthanum oxide and 0.1 to 1 part of degassing agents. The high-temperature smoke exhaust fan disclosed by the invention has the advantages that the design is scientific; the structure is simple; and the inner wall of the fan case is coated with one protection layer, so that the effects of promoting heat dissipation, preventing corrosion and resisting oxidization are effectively achieved, and the service life of the fan is ensured.

Description

technical field [0001] The invention belongs to the technical field of fans, and in particular relates to a high-temperature smoke exhaust fan. Background technique [0002] Due to the long-term high temperature and dense smoke environment of the exhaust fan, the temperature of the fan motor remains high during long-term use. Therefore, the cooling and cooling capacity of the fan is directly related to the service life of the fan. In addition, the harsh environment in which the fan is used can easily make its surface corroded, rusted or even damaged, which further shortens the service life of the fan and may even cause a safety accident. [0003] Therefore, providing a high-temperature smoke exhaust fan with good heat dissipation performance, anti-corrosion and anti-oxidation effects, and ensuring the service life of the fan has become an urgent problem to be solved by those skilled in the art.
