Detailed Description
The technical scheme of the utility model is described in more detail below with reference to the specific embodiments and the attached drawings.
Referring to fig. 1, a wall-scraping crystallization kettle comprises a stirrer 1, a stirring shaft 2, a frame 3 and a barrel 4, wherein the stirrer 1 is arranged at the top of the frame 3, the stirring shaft 2 is arranged at the middle position of the barrel 4 through the frame 3 and a bottom bearing device 5, and the stirring shaft 2 is connected with the stirrer 1. The barrel 4 comprises an upper barrel 401, a middle barrel 402 and a lower cone 403, jackets 6 are arranged on the peripheries of the middle barrel 402 and the lower cone 403, screw belts 7 which are uniformly and spirally distributed are arranged on the periphery of the stirring shaft 2, gaps between the screw belts 7 and the middle barrel 402 and between the screw belts and the lower cone 403 are 2-3mm, and the stirring shaft 2 is driven by the stirrer 1 to stir materials in the barrel 4 by driving the screw belts 7 fixed on the stirring shaft 2. The top and the bottom of the cylinder 4 are respectively provided with a mechanical seal 8 and a packing seal 9, so that the air tightness in the cylinder 4 is ensured, and materials crystallize under the heat transfer with the middle cylinder 402 and the lower cone 403. The upper right of the cylinder body 4 is provided with a feed inlet 10, and the lower left is provided with a discharge outlet 11 and a discharge valve 12.
The working principle of the wall scraping type crystallization kettle is as follows: the material solution enters the cylinder 4 through the feed inlet 10, the spiral belt 7 on the stirring shaft 2 stirs the material in the cylinder 4 through the transmission of the stirrer 1, the low-temperature refrigerant is introduced into the jacket 6, the solution exchanges heat with the low-temperature refrigerant in the jacket 6 under the action of the spiral belt 7 on the inner walls of the middle cylinder 402 and the lower cone 403, the temperature of the solution is reduced, the solubility of the material is reduced at low temperature, and the material is crystallized and separated out. Because the inner walls of the middle cylinder 402 and the lower cone 403 are low in temperature, the materials are crystallized and separated on the inner walls of the middle cylinder 402 and the lower cone 403, the stirring shaft 2 drives the spiral belt 7 to rotate continuously under the transmission of the stirring machine 1, and the spiral belt 2-3 mm away from the inner walls of the middle cylinder 402 and the lower cone 403 can scrape the materials crystallized and separated on the inner walls, so that the heat transfer between the solution in the cylinder 4 and the refrigerant in the jacket 6 is accelerated, and the separation process is accelerated. In this way, the stirring shaft 2 rotates continuously, and the spiral belt 7 scrapes off the materials separated by crystallization, so that the production efficiency of the crystallization kettle is accelerated. Through the wall-scraping type spiral belt 7, excessive crystallization materials are not adhered to the inner walls of the middle cylinder 402 and the lower cone 403, and after the materials are discharged through the bottom discharge valve 12, the residual materials in the cylinder 4 are few, the cleaning is easy, and even the cleaning process of the cylinder wall can be omitted.
