Description

Technical Field

[0001] The invention relates to the technical field of steel-lined plastic stirring tank structures, and in particular to a high-efficiency steel-lined plastic stirring tank. Background Art

[0002] With the continuous development of production technology, steel-lined plastic mixing tanks adopt a special rotational molding process, welding the steel mesh to the surface of the steel body, using pure low-density polyethylene as raw material, and using the rotational molding process to organically combine the steel plate, steel mesh and polyethylene into one. The inner lining surface is flat, smooth and strong, and has the advantages of corrosion resistance, no leakage, no peeling, wear resistance, resistance to a certain pressure and long service life. It is widely used in chemical, pharmaceutical, food, petroleum, dye, biochemical and other industrial production.

[0003] In the existing steel-lined plastic stirring tube, the stirring shaft generally uses the tangential force and the rebound force between the inner wall to stir and mix the high-concentration materials. When the forward and reverse structure is adopted, the bidirectional tangential force will increase the resistance in the stirring process, causing the overall pressure of the structure to increase. When the speed of the stirring shaft is reduced and the internal stirring forms a steady state, the low-density material will float on the upper layer and the high-density material will sink to the bottom, which will also reduce the mixing efficiency. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

[0055] Furthermore, when the winding wheel 302 contacts the connecting shaft 312, the winding wheel 302 no longer rotates continuously around the inner surface of the rubber ring 307 by rotating the connecting shaft 312, and the threaded spring piece 316 resets and rotates the connecting shaft 311 through deformation. When the winding wheel 302 contacts the rubber ring 307, the traction rope is wound up by the winding ring 303 to drive the fourth stirring plate 305 to stir the raw materials, wherein the fourth stirring plate 305 and the arc scraper 309 are driven by the rotating shaft 203 to rotate synchronously, and then the raw materials at the bottom of the equipment are scraped by the arc scraper 309, thereby preventing the raw materials from adhering to and affecting the stirring effect of the equipment.

[0056] Working principle: First, the tank cover 105 is inserted into the insertion groove 121 of the support ring 104 through the insertion rod 118 and is locked and fixed by the nut 116. The moving block 115 slides along the lifting groove 119, driving the toggle block 113 to flip, realizing the lifting and locking of the insertion rod 118. The clamping plate 110 applies uniform pressure to the tank body through the insertion rod 118 to ensure the sealing of the tank cover 105 and the support ring 104.

[0057] Secondly, the first stirring plate 206 is tilted upward at 15° to the horizontal plane to push the material up, and the second stirring plate 211 is tilted in the opposite direction at 15° to form a sinking vortex, and the bidirectional flow field eliminates material stratification, and the third stirring plate 215 has a wavy structure to generate a local shear force to break up high-viscosity material agglomerates. Further, the lining scraper 212 rotates closely against the inner wall of the plastic liner 120 to scrape off the adhered material, and the lower surface of the transverse scraper 217 contacts the rubber ring 307 to simultaneously clean the rubber ring 307 and the upper surface of the winding wheel 302. Further, the comb teeth of the first comb rod and the second comb rod are staggered to break up the material agglomerates to improve the mixing uniformity. At the same time, the hexagonal block 219 drives the third stirring plate 215 to swing around the second fixed axis 216 to expand the stirring range and cover the edge area of ​​the tank body.

[0058] Finally, when the winding wheel 302 reels the traction rope, the shaft plate rotates the fourth stirring plate under the drive of the deformation of the threaded spring piece 316. When the winding wheel 302 contacts the connecting shaft 312, the winding wheel 302 is flipped over under the drive of the elastic potential energy of the threaded spring piece 316, thereby reeling the traction rope through the winding ring. Furthermore, the arc scraper 309 is used to clean the bottom and side walls of the tank at the same time to prevent material accumulation and hardening.
