The design of 10 cubic meters fermentation tank
Abstract:Fermentation technology has become an indispensable technology in food, chemical and pharmaceutical industries.Besides,the Fermentation tank takes a large place in Fermentation process. The main steps in the design of a 10 cubic meter fermenter are detailed introduced in this paper,and I choose the design and strength check of the agitator shaft as my main research direction.In my opinions,my research will have a certain significance in practical engineering design.
In the process calculation, the diameter and height of the cylinder of the fermentor were roughly calculated.In this part,i has also sclected the shape of the head and have confirmed the height of the jack,the position of the impeller. the stirring power was calculated and the motor power was selected.With reference to the relevant standards and reference materials, the wall thickness of the cylinder, the wall thickness of the head, and the wall thickness of the jacket subjected to internal pressure are designed and calculated for the fermenter under the conditions of internal and external pressure.Also,I designed and checked the strength of the mixing paddle.The type of bearing, flange, bottom cover, flange and manhole are selected.At the same time, according to the four ways,including torsional deformation, the critical speed, strength calculation, and the radial displacement allowed at the shaft seal, I calculate the shaft diameter and check the strength.With reference to the national standard rules, the opening of the nozzle was reinforced by the method of equal area reinforcement.In the end, I did a simple introduction about the manufacture, inspection and installation of the mixing equipment.
Design result: I have designed a fermentation tank with a working volume of 10.The cylinder body material is S30408. The inner wall thickness is 14mm.The inner diameter is 1800mm and the height of the cylinder body is 3900mm.The equipment is mechanically sealed and stirred in the form of a three-layer mixing paddle.The rack is equipped with a mechanical seal and a single point bracket, and the support is supported by a support bracket and the stir shaft diameter is 130mm.
