Description

TECHNICAL FIELD

[0001] The utility model belongs to mechanical field, especially a stainless steel composite stirring shaft support device. BACKGROUND

[0002] The stirrer in the chemical reaction tank (pot, tank) is a device that mixes and uniformly distributes reactants in the entire reactor to promote the reaction of reactants. Its principle is to mix the reactants by the stirrer and make them uniformly distributed in the reaction tank (vessel) to increase the contact area between the reactants and reduce the mass transfer resistance between the reactants, thereby improving the reaction rate and reaction efficiency. At the same time, the stirrer can also ensure the uniform distribution of temperature, pH value and other parameters during the reaction process, thereby improving the quality and stability of the reaction. However, in chemical reactions, especially in phosphorus chemical and copper-lead-zinc chemical reaction tank, the materials are mostly sulfuric acid and other strong corrosive substances containing chloride ions and fluoride ions, which can easily corrode the stirring shaft. Moreover, the stirring shaft of the stirrer is usually a cantilever structure, which not only affects the service life but also often causes insufficient rigidity of the stirring shaft, affecting the stirring effect. Therefore, the current stirring shaft is mostly made of stainless steel, but the cost is high and the use is not satisfactory. Moreover, the rigidity of the stirring shaft has not been fundamentally solved. Therefore, how to solve the rigidity of the stirring shaft and ensure the stirring effect is a technical problem to be solved. SUMMARY

[0003] In view of the above situation, in order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a stainless steel composite stirring shaft support device, which can effectively solve the rigidity of the stirring shaft of the stirrer in chemical production, prolong the service life and ensure the stirring effect.

[0004] The technical scheme solved by the utility model is a stainless steel composite stirring shaft support device, which comprises a stainless steel sleeve, a carbon steel pipe and a support frame. The carbon steel pipe is tightly sleeved at both ends with symmetrical stainless steel sleeves connected together. The support frame is a frame composed of a horizontal support and a vertical support connected together. One end of the horizontal support corresponding to the stainless steel sleeve is welded together with the end of the carbon steel pipe through soldering (welding point). The vertical support is provided with symmetrical mounting holes for mounting stirring blades at the upper and lower ends.

[0005] The utility model has novel and unique structure, is easy to produce and manufacture, convenient to install and use, can effectively support the stainless steel composite stirring shaft, ensure the rigidity and use effect of the stirring shaft, prolong the service life of the stirring shaft, and has significant economic and social benefits. BRIEF DESCRIPTION OF DRAWINGS

[0006] Figure 1 It is a sectional view of the utility model. DETAILED DESCRIPTION

[0007] The utility model discloses a specific embodiment in detail below in connection with the drawings.

[0008] By Figure 1 As shown in the utility model disculous a stainless steel composite stirring shaft support device, including stainless steel sleeve, carbon steel pipe and support frame, carbon steel pipe 1 both ends outer tight sleeve has the symmetry of stainless steel sleeve 5 connected together, support frame is by transverse support 2 and longitudinal support 6 connected together constitute the frame, and the corresponding end of transverse support 2 is through soldering tin (soldering point) 4 and the corresponding end of stainless steel sleeve 5 and carbon steel pipe 1 are welded together, and the upper and lower ends of longitudinal support 6 are equipped with the symmetry of mounting hole 7 for installing stirring vane.

[0009] In order to use conveniently and guarantee the use effect, the carbon steel pipe 1 is hollow circular, and the outer diameter is 508mm, and the wall thickness is 40mm;

[0010] The wall thickness of the stainless steel sleeve 5 is 6mm, and the outer diameter is 520mm, and the inner diameter of the stainless steel sleeve 5 is equal to the outer diameter of the carbon steel pipe 1;

[0011] The end of the transverse support 2, the inner end of the stainless steel sleeve 5 and the outer wall of the carbon steel pipe 1 form a triangular weld, and the transverse support 2, the stainless steel sleeve 5 and the carbon steel pipe 1 are firmly welded together through the soldering tin 4, so that the welding effect is guaranteed.

[0012] The reinforcing rib plate 9 is arranged between the transverse support 2 and the longitudinal support 6.

[0013] When the utility model is used, the unseat bearing is arranged on the suspended stainless steel composite stirring shaft (the original structure), the stirring vane 3 is fixed on the longitudinal support 6 by using the screw 8 and the mounting hole 7, and the stirring structure is formed, and other use conditions are same as the prior art.

[0014] As can be seen from the above structure, the utility model is improved to the stirring structure of the original stirrer, that is, the support device is arranged on the stirring shaft, the original stirring vane is directly arranged on the stirring shaft, and is changed to be arranged on the support device, so that the corrosion of the material to the stainless steel composite stirring shaft is prevented, the stainless steel composite stirring shaft protection is strengthened, that is, the rigidity (rigidity) is guaranteed, the service life is prolonged, the material is saved, the cost is reduced, the service life can be improved by more than 2 times, the stirring efficiency is improved, and remarkable economic and social benefits are obtained.
