Shuitou cad training
The design of the reactor is good. CAD drawings are drawn by many designers, but they can only be made by themselves, providing you with some parameters, as long as you can get them through CAD. The design of the reaction kettle mainly includes: (1) strength, stiffness and stability calculation of the kettle body and structural design; (2) Strength and stiffness calculation and structural design of jacket; (3) designing the contents of the flange connection structure of the kettle body, selecting and inspecting the nozzle and flange fittings (4) selecting and reinforcing the calculation holes (5); (6) Selection of endoscope; Structure and size design of weld (7); (8) Selection of motor and reducer; (9) Size design of mixing shaft and box impeller; (10) coupling; (1 1) Structure and scale design of the frame (12) Structure and size design of the bottom cover (13), shaft parts drawing in the form of sealing drawing (14), and mixing meeting. The reactor design flow is as follows: 1 reactor pressure vessel design 1. 1 kettle body, with the kettle body determined by (1) as a cylinder, and. : = 1.24 1 (), which is expected, so the operating pressure of the reactor body (2) is 0.52. [1] Table 16-9 shows that: = 0.6 1.2 The design parameters of the kettle body are determined by the design pressure of the cylinder with the wall thickness of the kettle body (1): = (1.051) = Hydrostatic pressure: ≈; = & lt5%, which can be ignored; Calculation pressure: 1. 1 == 0.52 Design temperature:145 C; Weld coefficient = 0.85 (local nondestructive testing), allowable stress: According to the material 0Cr 18Ni 10Ti, the design temperature is145 C [1] Table 14-4 Known =/kloc-. Negative deviation of steel: = 0.25 (GB 6654-96); Corrosion allowance: = 1. (2) Considering the thickness obtained from the cylinder design formula, then =+= 4.64, and the head wheel (1) designed for/kloc-0 kettle body adopts the head of standard ellipsoid code EHA standard JB/T4746-2002. (2) The determined design parameters and the wall thickness design of the cylinder (3) head are obtained by the following formula: Considering that the size, volume and weight of the circular and straight head (4) are determined according to the document [1 table 14-4], the height of the straight head: 25 volume: 0.3208 depth: 350. Internal surface area: 1.9304 1.4 Design barrel length, == 0.889()= 889 rounds: = 890 Audit kettle length-diameter ratio: = 0.954, so the design of 1.5 external pressure barrel meets the requirements (1). (2) Experiment and wrong design of cylinder; Cylinder wall thickness = 6, then: = = 6-1.25 = 4.75 =131.17×1313. = 255 1 1.7, and the cylinder is short. Critical pressure of cylinder: = 0.469 () = 3: 0.469/3 = 0.156 (= 0.1) < = 0.156 = 6 Assuming that the stability requirements are met. Cylinder = wall thickness 6. The algorithm of the graph is designed as a tubular body with wall thickness (3)= 6, so: = 6-1.25 = 4.75 () =1312 = 276.2 The calculated length of the tubular body:' =+h = 890+(350-. 0.0004。 From the reference [1], select the material line of the temperature corresponding to the intersection of vertical lines of points in the horizontal coordinates of point 15-7 = 4× 10-4, and this point intersects the right longitudinal axis along the horizontal line again, with the coefficient value ≈ 46 =1.79× 69. = A:= 0. 166().= 0. 1 & lt; = 0. 166, assuming that = 6 is reasonable and the lap wall thickness = 6. [1] Table16-5 = Article 6 193 of cylinder quality:193× 0.890 =171.9 () Internal surface area? Cylinder: 4.09 = 1.6 The external pressure design of the head (1) consists of the design head pressure and the external pressure of the same design, that is, the design pressure = 0. 1 cylinder wall thickness. (2) Calculate the wall thickness of the head = 6, then: =-= 6- 1.25 = 4.75 (), and the standard oval head = 0.9, = 0.9×1300 =170 (). = 0.223, assuming that = 6 is too large, considering the welding and the cylinder, the wall thickness of the cylinder head is the same, so they choose = 6. As shown in figure 1, the head mass is 89.2 () and the jacket head size of the kettle reactor is 22. 1 In figure 1, the nominal diameter of the jacket (1) is determined, and the head fluidity of the oil-thermal jacket reactor structure is determined, with the jacket diameter =1. Jacket = 1600 = 1600(2) Jacket is called the design condition of a single device, and the dielectric pressure of the jacket.
