Description

Technical Field

[0001] This invention relates to the field of ion exchange technology, and more particularly to a mixing machine for producing gel-type strong basic anion exchange resin. Background Technology

[0002] Silica gel-based strong anion exchange resins must be prepared through a complex synthesis process. The main raw materials are basic styrene, silicone oil, and sodium sulfate. In the preparation of the resin, the raw materials are first mixed and stirred, and a certain temperature is increased to promote the mixing of the solution. Then, the solution is filtered through a filter column for overall purification. After drying, the solution undergoes foaming, furnace calcination, solvent recovery, and other steps to finally prepare the styrene-based strong basic anion exchange resin.

[0003] According to research, most existing raw material mixing devices utilize extended branches in conjunction with a high-speed rotating main shaft to stir and mix various raw materials inside the raw material tank. However, this mixing method has a drawback: when mixing materials with high viscosity, the effect is not obvious, and excessive raw materials may even stick to the mixing mechanism during discharge, which is not conducive to the complete discharge of the batch. A large amount of residue will still remain in the next batch of production, requiring complete disassembly and rinsing, which is time-consuming, labor-intensive, and has low production efficiency. Summary of the Invention

[0004] To address the technical problem in existing mixing devices where a significant amount of material remains adhered to the stirring rod after discharge, this invention employs the following technical solution: A mixing machine for producing gel-type strong basic anion exchange resin includes a mixing tank with an upward-opening, cylindrical structure. A horizontally fixed frame plate is attached to the top opening of the mixing tank. A sliding bearing is embedded in the middle of the frame plate, and a stirring rod extending into the mixing tank is rotatably connected to the sliding bearing. The bottom end of the stirring rod has two centrally symmetrical, foldable arc-shaped stirring blades, the outer diameter of which is the same as the outer diameter of the stirring rod. A circular hole is also provided near the sliding bearing on the frame plate, and a vertical rack and pinion scraper is slidably inserted into the hole. The rack and pinion scraper is connected to the stirring rod... The mixing rods are parallel to each other; the bottom end of the rack scraper is equipped with a disc-shaped scraper plate; and the scraper plate is slidably connected in the mixing tank; the middle of the scraper plate has a through hole for the mixing rod to pass through, and the bottom end of the through hole is equipped with two symmetrically distributed rubber spiral scrapers; through the mixing arc-shaped blades that can be folded together at the bottom end of the mixing rod, and the rubber spiral scrapers that are attached to the outer wall of the mixing rod at the bottom end of the through hole, when the mixing is finished and discharge is required, it is only necessary to control the scraper plate to descend and scrape the tank wall of the mixing tank. At the same time, the rubber spiral scrapers also clean the outer walls of the upper mixing rod and the two mixing arc-shaped blades.

[0005] Furthermore, two centrally symmetrical shaft lugs are fixed near the center of the bottom end of the stirring rod, and each shaft lug is provided with a short shaft. A hinge plate, hinged to the short shaft, is fixed near the top of each of the two opposing stirring arc blades. A centrally symmetrical spring fixing plate is welded and fixed below one of the shaft lugs in each set, and a return spring is fixed between the spring fixing plate and the inner arc side of the corresponding stirring arc blade near its top. By providing two stirring arc blades with return springs, the two stirring arc blades can be opened even without rotational stirring. Then, with the help of centrifugal force, the opening amplitude of the two stirring arc blades is increased, thereby improving the mixing effect.

[0006] Furthermore, the bottom of the mixing tank is designed as a cone-shaped, downward-pointing, leak-proof structure, and a discharge valve is provided at the bottom of the mixing tank; the discharge valve is a ball valve; it is easy to clean and has a good anti-clogging effect.

[0007] Furthermore, a feeding notch groove is reserved near the front of the top circumferential edge of the mixing barrel, and the height of the feeding notch groove is equal to the thickness of the scraper. When feeding, the scraper can be pulled up above the feeding notch groove, and the raw material can be slid into the mixing barrel from the feeding notch groove.

[0008] Furthermore, a vertical support column is fixed near the center of the upper surface of the fixed frame plate, and an anti-torsion groove is opened on the side of the support column near the stirring rod. A boss slider is slidably connected in the anti-torsion groove, and a sliding bearing seat that is sleeved on the stirring rod is fixed at the end of the boss slider away from the bottom of the groove. An anti-detachment bearing that matches the outer diameter of the stirring rod is fixed in the middle of the sliding bearing seat. In this embodiment, the anti-detachment bearing is two mutually symmetrical tapered roller bearings. A drive motor is fixed to the side of the sliding bearing seat away from the boss slider by bolts, and a driving pinion is fixed to the top of the output shaft of the drive motor. A driven gear that meshes with the driving pinion is sleeved and fixed to the top of the stirring rod; thus, the stirring rod can mix materials at any height.

[0009] Furthermore, a U-shaped pressure plate is fixed to the bottom end of the rack scraper top rod, and the bottom end of the U-shaped pressure plate is fixed to the upper surface of the scraper plate by bolts; the outer circumference of the rack scraper top rod has a toothed surface on the side away from the support groove column, and a horizontally rotating feeding drive rod is provided on the side of the upper surface of the fixed frame plate near the toothed surface. A drive gear and a rocker arm are fixed to both ends of the feeding drive rod, and the drive gear meshes with the toothed surface; when scraping material, it is necessary to control the scraper plate that is slidably connected to the inner wall of the mixing barrel to descend, simply turn the rocker arm to slowly drive the rack scraper top rod to descend.

[0010] Furthermore, the top of the supporting column is reserved with a cantilever shaft seat extending above the sliding bearing seat, and a horizontal double-headed fixed pulley is rotatably connected to the cantilever shaft seat. The top of the rack scraper is fixed with a rope fixing wing plate, and the upper surface of the rope fixing wing plate is fixed with a suspension rope near the front and rear ends respectively. The outer circumference of the wheel discs at both ends of the double-headed fixed pulley is opened with rope grooves, and the suspension rope passes around the corresponding rope grooves and is fixed to both ends of the sliding bearing seat. While controlling the rack scraper to descend, the stirring rod and the stirring arc plate at its bottom end can be pulled up, and then, in conjunction with the two rubber spiral scrapers attached to the outer wall of the stirring rod, the residue on its surface can be scraped off.

[0011] Furthermore, a wear-resistant slip ring is also embedded in the circular hole. The height of the wear-resistant slip ring is greater than the thickness of the fixed frame plate to ensure that the rack scraper rod always moves up and down in a vertical state. The inner edge of the top circumference of the insertion hole is chamfered to facilitate the insertion of the stirring rod and the two stirring arc-shaped blades after they are pulled out.

[0012] Furthermore, two mutually symmetrical sidewall blocks are fixed near the center of the outer circumference of the mixing tank, and coaxial shafts are fixed on opposite sides of the two sidewall blocks. A main bearing seat is rotatably fitted onto each of the two shafts. The bottom ends of the two main bearing seats are fixed with the same support frame. A driven worm gear ring is fitted and fixed to the outer wall of one of the sidewall blocks. A folded motor frame is fixed near the rear of the outer wall of the main bearing seat on that side. A reduction motor is fixed to the top of the folded motor frame, and a worm gear meshing with the driven worm gear ring is fixed to the top of the output shaft of the reduction motor. This arrangement allows the entire tank to tilt during mixing, preventing materials from settling to the bottom. Combined with the vortex generated by the rotating stirring disc, the materials can be mixed more thoroughly.

[0013] Furthermore, the worm wheel center angle of the driven worm wheel ring is 45 degrees to 60 degrees, and the reduction motor has a self-locking function; with this setting, the maximum tilt angle of the mixing barrel can be controlled to ensure that the whole thing will not overturn.

[0014] The beneficial effects of this invention are as follows: 1. By using the foldable arc-shaped stirring blades at the bottom of the stirring rod, along with the rubber spiral scraper attached to the outer wall of the stirring rod at the bottom of the insertion hole, when the mixing is finished and discharge is needed, you only need to control the scraper to descend and scrape the wall of the mixing bucket. At the same time, the rubber spiral scraper will also clean the outer walls of the upper stirring rod and the two arc-shaped stirring blades.

[0015] 2. By setting two stirring arc-shaped blades with reset springs, the two stirring arc-shaped blades can be opened up when there is no rotation stirring. Then, with the action of centrifugal force, the opening range of the two stirring arc-shaped blades is increased, thereby improving the mixing effect.

[0016] 3. Because a mechanism is set on the outer wall of the mixing tank to help the mixing tank tilt at a certain angle, the mixing tank can be set to tilt during mixing to prevent the material from sinking to the bottom and falling into the mixing dead zone; together with the vortex generated by the rotating stirring arc blades, the material can be mixed more thoroughly.
