Description

Stainless steel stirrer for spraying carbon steel surface Technical Field The utility model belongs to the technical field of stirrers, and particularly relates to a stirrer for spraying stainless steel on the surface of carbon steel. Background In the industrial production processes of chemical industry, food, pharmacy and the like, the stirrer is used as key equipment for realizing material mixing and reaction, and the performance of the stirrer plays a decisive role in production quality and efficiency. Especially at the end of material concentration, the viscosity of the material is obviously increased, and caking and agglomeration are extremely easy to occur, which brings great challenges to stirring operation. Conventional carbon steel agitators present a number of disadvantages in facing the problem of caking at the end of material concentration. Under the conventional stirring mode, the stirring blade can bear great resistance when processing high-viscosity caking materials. Once the resistance exceeds the bearing limit of the blade, the blade and the agglomerated materials are easy to expand, deform and even break, so that not only are the components of the stirrer damaged, but also the stirring efficiency is greatly reduced, and the production period is seriously prolonged. Moreover, the traditional stirrer lacks a targeted solution, can not effectively crush the caking materials, can only continuously stir in a low-efficiency manner, and is difficult to meet the requirements of industrial production on stirring efficiency and quality. In addition, even if partial stirrers can barely deal with caking materials, the stirring device can also operate under high load for a long time, the equipment failure risk is increased, the maintenance cost is increased, the production rhythm can be disturbed due to frequent shutdown maintenance, and economic loss is brought to enterprises. Disclosure of utility model Aiming at the problems, the utility model aims to provide a stainless steel stirrer sprayed on the surface of carbon steel, which solves the problems of low stirring efficiency and easy damage of the stirrer caused by caking and agglomeration of materials at the end of concentration. In order to achieve the purpose, the technical scheme is that the stainless steel stirrer is sprayed on the surface of carbon steel, the stainless steel stirrer comprises a main shaft, an upper fixing piece, a lower fixing piece and a smashing piece are fixedly arranged on the lower side of the main shaft, the upper fixing piece comprises a first optical axis fixing seat with the same structure as the lower fixing piece, a sleeve is connected to the closed end of the first optical axis fixing seat, a mounting groove is formed in the side face of the sleeve, a pawl is arranged in the mounting groove, a paddle stirrer is rotatably arranged on the outer side of the sleeve, the paddle stirrer comprises a sleeve, a ratchet groove is formed in the inner wall of the sleeve, the ratchet groove is in one-way meshing with the pawl, stirring blades are arranged on the outer side of the sleeve, the smashing piece comprises a second optical axis fixing seat with the same structure as the lower fixing piece, and smashing teeth are formed on the curved surface side face of the closed end of the second optical axis fixing seat. The utility model has the advantages that the main shaft drives the paddle stirrer to rotate through the ratchet mechanism to stir materials when the main shaft rotates positively, and when the materials are agglomerated and aggregated at the end of concentration, the main shaft rotates reversely and does not generate power transmission with the paddle stirrer, so that the expansion deformation or fracture of the paddle stirrer and the agglomerated materials is avoided, and meanwhile, the crushing piece gradually crushes the agglomerated materials in the rotating process, so that the stirring production efficiency is improved. A one-way engagement ratchet groove for stabilizing the pawl; As a further improvement of the technical scheme, one end of the pawl is rotatably inserted with a connecting shaft, the upper end and the lower end of the connecting shaft are connected with the inner wall of the mounting groove, the pawl and the mounting groove are respectively connected with the two ends of the reed, and the reed is of a V-shaped plate structure. The improved one-way clamping ratchet groove has the beneficial effects that the pawl can be rotated to expand and stably one-way clamping ratchet groove under the support of the reed, so that the upper fixing piece drives the paddle stirrer to stably rotate in one direction. In order to further improve the stability of the transmission between the upper fixing piece and the paddle stirrer; as a further improvement of the technical scheme, the number of the mounting grooves is multiple, and the mounting grooves are equidistantly arranged around the axis of the sleeve.
