Autoclave with internal circulation heating function

Abstract

The invention discloses an autoclave with internal circulation heating function. The autoclave comprises an autoclave body, a discharge port is fixedly connected to the center of the lower side of the autoclave body, an electromagnetic valve is fixedly installed on the discharge port, four supports are fixedly connected to the edge of the lower side of the autoclave body, a first connecting rod is fixedly connected between every two supports, and a heat preservation mechanism is fixedly connected to the first connecting rod; a plurality of heating plates are fixedly connected to the inner wall of the kettle body, a plurality of electric heating wires are arranged in the heating plates, fixing blocks are fixedly connected to the two sides of the upper end of the kettle body, kettle covers are arranged above the kettle body, a stirring mechanism is fixedly connected to the kettle covers, discharging openings are formed in the kettle covers, limiting holes are formed in the two ends of the lower sides of the kettle covers, and connecting holes are formed between the kettle covers; the inner parts of the connecting holes are all provided with bolts; the heat preservation mechanism comprises a frame; the upper side of the frame is provided with a T-shaped groove. According to the autoclave with the internal circulation heating function, internal heating circulation and heat preservation are facilitated, the bolts are taken down, and the autoclave cover can be taken down to clean and maintain the interior of the autoclave body.

Description

technical field [0001] The invention relates to an autoclave, in particular to an autoclave with internal circulation heating, and belongs to the field of autoclaves. Background technique [0002] Autoclave refers to a kind of reactor operated under high pressure. According to the process requirements, there are two kinds of autoclave with agitator and without agitator. The structure of the former is the same as that of the stirring equipment. Cylinder, the shell is relatively thick, usually made of stainless steel for high temperature resistance and corrosion resistance, and carbon steel or low alloy steel is also used as the outer shell, stainless steel is the inner material, which can be directly made of composite board or lining; (2) There are generally no holes on the kettle body, and the connecting pipes, interfaces and accessories are all set on the kettle cover; (3) The top of the kettle is equipped with a safety relief device, such as a safety valve, a bursting disc...

AI Technical Summary

Problems solved by technology

[0003] Although the traditional autoclave is equipped with a heating device, it cannot recirculate the heat in the autoclave, resulting in slow heat transfer and uneven temperature in the autoclave, and the traditional autoclave is generally not equipped with a heat preservation device, resulting in heat loss and loss
