Embodiment Construction

[0009] refer to figure 1 , the specific embodiment adopts the following technical scheme: it is composed of a heating wire 1, an insulating layer 2 and a tetrafluoroplastic layer 3, the heating wire 1 is arranged inside the insulating layer 2, and the outer side of the insulating layer 2 is provided with a tetrafluoroplastic layer 3.

[0010] The tetrafluoroplastic layer 3 has the advantages of corrosion resistance and high temperature resistance, and can well protect the heating wire 1 from corrosion during use.

[0011] The tetrafluoroplastic layer 3 is made of polytetrafluoroethylene, and polytetrafluoroethylene is one of the materials with the best corrosion resistance in the world, so it has the reputation of "King of Plastics". It can withstand any chemical medium for a long time. Its production has solved many problems in my country's chemical, petroleum, pharmaceutical and other fields. Compared with other plastics, polytetrafluoroethylene has the characteristics of e...

Abstract

The invention provides a hydrochloric acid pool heating pipe which relates to a heating device used in a hydrochloric acid pool for washing seeds in a seed station. The hydrochloric acid pool heatingpipe comprises an electric heating wire (1), an insulating layer (2) and a tetrafluoroethylene layer (3), wherein the electric heating wire (1) is arranged in the insulating layer (2), and the tetrafluoroethylene layer (3) is arranged outside the insulating layer (2). The hydrochloric acid pool heating pipe has simple structure, relieves the corrosion of the hydrochloric acid to the heating wire to prolong the service life of the heating wire, has no need of replacing the heating wire frequently, and reduces the cost for washing seeds.

Description

Technical field: [0001] The invention relates to a heating device used in a hydrochloric acid pond for bathing silkworm eggs, in particular to a hydrochloric acid pond heating tube. Background technique: [0002] Stimulation by hydrochloric acid immersion to promote the release of diapause is to realize the artificial incubation of silkworms. It is a method commonly used in sericulture at home and abroad. Branch ash, straw ash shower juice bath species. Bathing seeds with these aqueous solutions promotes the release of diapause of silkworm eggs and plays a weak role in disinfecting the surface of eggs. The operation method of bathing seeds is either showering with solution, or soaking the silkworm eggs in the solution, and the soaking time is as short as a moment and as long as several days. The method of bathing seeds in history is constantly developing, and the purpose of bathing seeds is no longer limited to cleaning the dirt on the egg surface, and further attention is...
