Jacket unit, jacket tank and manufacture method of jacket tank

Abstract

The invention discloses a jacket unit, which comprises a tank body plate and a jacket plate, wherein the thickness of the tank body plate is greater than that of the jacket plate; the periphery of the jacket plate is aligned to the periphery of the tank body plate and fixedly connected with the periphery of the tank body plate; and the middle part of the jacket plate is fixedly connected with the tank body plate through a plurality of uniformly distributed points or lines, and the part, which is not fixedly connected to the tank body plate, of the jacket plate and the tank body plate are separated from each other to form a fluid channel.

Description

technical field [0001] The invention relates to a jacket unit, a jacket tank using the jacket unit and a manufacturing method of the jacket tank. Background technique [0002] In the industrial production of beer, beverages, etc., it is often necessary to cool the tank equipment used in production. For example, during the fermentation process, the material in the tank will release a large amount of heat, and the tank body needs to be cooled to maintain the temperature required for fermentation in the tank body. Therefore, it is necessary to set up heat transfer elements for these tank equipment to conduct the reaction heat of the materials in the tank. [0003] At present, one type of heat transfer element commonly used in the field is a jacketed heat transfer element. The tank body using the jacketed heat transfer element has a two-layer structure, that is, the tank body used to accommodate the material and the jacket plate arranged on the outside of the tank body. figur...

Problems solved by technology

However, since the length and width of the jacket plate 3 are smaller than that of the tank body plate 4, after the jacketed tank 1 is formed, the jacket plate 3 is not continuous in the circumferential direction and the longitudinal direction of the outer surface of the tank body 2, so the jacket The plate 3 only strengthens the part of the tank body it covers, but has no reinforcement effect on the tank body 2 as a whole

Therefore, when designing the jacketed tank 1, it is usually necessary to calculate the thickness of the tank body plate 4 according to the standard of the internal pressure vessel, that is, the thickness of the tank body plate 4 must be sufficient to withstand the pressure of the material in the tank body 2, which is not conducive to reducing the The thickness of the tank plate 4 makes the material cost of the entire jacketed tank 1 relatively high
