[0010] Figure 2 The utility model is a schematic diagram of the development of a spiral blade in the spiral stirring device in the reactor. DETAILED DESCRIPTION
[0011] The present invention is further described below in conjunction with the accompanying drawings and specific implementations.
[0012] See also Figure 1 The spiral stirring device in the reactor shown in the figure includes two stirring shafts 10, 20 and a sleeve 30 for connecting the two adjacent stirring shafts 10, 20. The diameter of the two stirring shafts 10, 20 is 160mm, the length is 5998mm, and the material is Q235. The two stirring shafts 10, 20 can be solid shafts or hollow shafts. A plurality of spiral blades 40 are welded on each stirring shaft 10, 20. The thickness of the spiral blades 40 is 20mm and the material is also Q235. See in particular Figure 2 , the spiral blade 40 is fan-shaped when unfolded.
[0013] An end shaft 11, 21 is respectively provided at the adjacent ends of two adjacent stirring shafts 10, 20; the end shafts 11, 21 can be integrally formed with the stirring shafts 10, 20, or welded to the adjacent ends of the two stirring shafts 10, 20 by welding, and the diameter of the end shafts 11, 21 is 130 mm.
[0014] During processing, the end shafts 11 and 21 of the two adjacent stirring shafts 10 and 20 are inserted into the sleeve 30 and the ends of the two adjacent stirring shafts 10 and 20 are respectively welded to the ends at both ends of the sleeve 30. After welding, correction is performed and the straightness is controlled within 2mm; the outer diameter of the sleeve 30 is 159mm, the inner diameter is 130mm, and the material is also Q235.
[0015] The spiral blades 40 on two adjacent stirring shafts 10 and 20 are welded and connected at their adjacent locations to form a continuous spiral blade.
[0016] In order to enhance the connection strength between the end shafts 11, 21 and the sleeve 30, the end shafts 11, 21 and the sleeve 30 of two adjacent stirring shafts 10, 20 are connected by a pin 51, 52 respectively penetrating the end shafts 11, 21 and the sleeve 30. The two pins 51, 52 are arranged in a cross shape.
[0017] The welding technology requirements used in the spiral stirring device in a reaction furnace shown in the figure shall be implemented in accordance with JB / T5000.3-1998.
