Description

Technical Field

[0001] The utility model relates to the field of sodium thiosulfate production equipment, in particular to a crystallization stirring tank used for sodium thiosulfate. Background Art

[0002] The purpose of stirring during the sodium thiosulfate crystallization process is to promote uniform mixing of the components in the solution and dissipate heat, and to prevent local oversaturation from causing rapid precipitation and growth of crystals. In the production process of sodium thiosulfate, the crystallization stirring tank is one of the core equipment, and its performance directly affects the quality, output and production efficiency of sodium thiosulfate crystals. The traditional sodium thiosulfate crystallization stirring tank is relatively simple in design, with low stirring efficiency, which can easily lead to problems such as crystal scaling and uneven particle distribution, thus affecting the overall quality of sodium thiosulfate crystals.

[0003] To this end, we propose a sodium thiosulfate crystallization stirring tank with multi-layer regulating blades, which makes the stirring more uniform, reduces the problems of crystal scaling and uneven particle distribution, and improves the quality and purity of the crystals. Utility Model Content

[0004] In order to overcome the shortcomings of low stirring efficiency of a conventional sodium thiosulfate crystallization stirring tank, which is prone to crystal scaling and uneven particle distribution, the utility model provides a sodium thiosulfate crystallization stirring tank with multi-layer regulating blades.

[0005] The crystallization stirring tank for sodium thiosulfate comprises a supporting frame, a charging barrel is fixedly connected to the supporting frame, a discharging pipe is connected to the bottom end of the charging barrel, a detachable lid is connected to the top end of the charging barrel, a fixing frame is fixedly connected to the lid, a motor is fixedly connected to the fixing frame, a rotating rod is fixedly connected to the output shaft of the motor, the rotating rod extends into the charging barrel, a stirring rod is fixedly connected to the rotating rod, and also comprises equidistantly distributed connecting sleeves, the equidistantly distributed connecting sleeves are fixedly connected to the stirring rod, a stirring blade is rotatably connected to the connecting sleeve, a clamping block is slidably connected to the connecting sleeve, and a spring is connected between the clamping block and the adjacent connecting sleeve.

[0006] Furthermore, a slot is provided on one side of the stirring blade close to the block, and the block is inserted into the adjacent slot.

[0007] Furthermore, it also includes an infusion tube, which is fixedly connected to the charging barrel, and the top of the support frame is fixedly connected to a water tank. Both ends of the infusion tube are connected to the water tank, and one end of the infusion tube extending out of the charging barrel is fixedly connected to a water pump, and a cooling block is fixedly connected to the water tank.

[0008] Furthermore, it also includes a connecting rod, which is fixedly connected to the rotating rod, and a scraper is fixedly connected between the connecting rods, and the scraper is in contact with the inner wall of the charging barrel.

[0009] Furthermore, the barrel wall of the loading barrel is a hollow structure, and the infusion tube is coiled inside the barrel wall of the loading barrel.

[0010] Furthermore, a cover plate is connected to the top of the water tank.

[0011] The beneficial effects of this application are:

[0012] 1. The stirring rod rotates to stir the solution in the loading barrel. The stirring rod also drives the stirring blade to rotate, further stirring the solution and improving the stirring efficiency. At the same time, under the action of the block and the spring, the stirring blade can rotate to adjust the angle, and then adjust the contact area with the solution according to the stirring needs, making the stirring more uniform, reducing the problems of crystal scaling and uneven particle distribution, and improving the quality of the crystal.

[0013] 2.

[0014] 3. The rotation of the scraper can scrape off the solution and crystals attached to the inner wall of the loading barrel to ensure uniform stirring and prevent the solution from staying on the inner wall of the loading barrel and being unable to be fully stirred.
