[0002] Selenium extraction refers to the process of extracting selenium elements from various selenium-containing materials. Selenium is an important strategic rare metal, widely used in chemical, petroleum, pharmaceutical, electronic, metallurgical and other industries. There are many methods for extracting selenium, including extracting organic selenium from natural selenium-rich agricultural products, extracting selenium from selenium-rich agaricus blazei, extracting selenium from low-grade selenium-containing materials, etc. The water solution concentration device for selenium extraction is a device for extracting and concentrating selenium elements from aqueous solution. This device usually includes two stages of solvent extraction and vacuum concentration. First, the active ingredients in the raw materials are dissolved and extracted by solvent (such as water, ethanol, etc.), and then the solvent in the extract is evaporated by vacuum concentration technology to obtain high-concentration extract.

[0024] Embodiment 1: the preferred embodiment of the water solution concentration device for selenium extraction provided by the utility model is as shown in the figure: Figures 1 to 6 As shown: a water solution concentration device for selenium extraction, comprising a heating extraction barrel 1;

[0025] The heating extraction barrel 1 top surface is communicated with a feed pipe 2;

[0026] The heating extraction barrel 1 outer wall is fixedly installed with a support leg 3;

[0027] And the processing assembly 4 arranged above the support leg 3, the processing assembly 4 includes a cleaning assembly 41 arranged above the support leg 3, the cleaning assembly 41 includes a support 411 fixedly installed on the top surface of the heating extraction barrel 1, the top surface of the support 411 is fixedly installed with a motor 412, the output end of the motor 412 is fixedly installed with a rotating column 413, the end of the rotating column 413 is fixedly installed with a first bevel gear 414, the outer wall of the first bevel gear 414 is engaged with a second bevel gear 415, the second bevel gear 415 is sleeved with a sleeve pipe 416 in the inside, the outer wall of the sleeve pipe 416 is fixedly installed with a rotating plate 417, the bottom of the rotating plate 417 is provided with a limiting groove 418, the limiting groove 418 is slidably provided with a limiting block 419 in the inside, the side wall of the limiting block 419 is fixedly installed with a spring 420, the outer wall of the limiting block 419 is fixedly installed with a scraper 421, the outer wall of the first bevel gear 414 is engaged with a third bevel gear 422, the third bevel gear 422 is sleeved with a rotating rod 423 in the inside, the outer wall of the rotating rod 423 is fixedly installed with a stirring rod 424.

[0028] When the selenium needs to be extracted, the water solution of the selenium needs to be concentrated. The solution is added into the heating extraction barrel 1 through the feeding pipe 2. At this time, the motor 412 is started. The rotating column 413 fixedly installed at the output end of the motor 412 rotates. The first bevel gear 414 fixedly installed at the end of the rotating column 413 rotates. Since the first bevel gear 414 is engaged with the second bevel gear 415, the first bevel gear 414 drives the second bevel gear 415 to rotate under the limitation of the second bevel gear 415. The sleeve pipe 416 sleeved in the second bevel gear 415 rotates. The sleeve pipe 416 drives the rotating plate 417 fixedly installed on the outer wall of the sleeve pipe 416 to rotate. The rotating plate 417 drives the limiting block 419 slidingly arranged in the rotating plate 417 to rotate. The limiting block 419 drives the scraper 421 to rotate. The solution in the heating extraction barrel 1 is stirred, so that the heating is more uniform. The first bevel gear 414 drives the third bevel gear 422 engaged with the first bevel gear 414 to rotate. The third bevel gear 422 drives the rotating rod 423 sleeved in the third bevel gear 422 to rotate. The stirring rod 424 fixedly installed on the outer wall of the rotating rod 423 rotates. Since the rotating rod 423 and the sleeve pipe 416 rotate in opposite directions, the sleeve pipe 416 and the rotating rod 423 rotate in opposite directions under the limitation of the first bevel gear 414, the second bevel gear 415 and the third bevel gear 422. The solution in the heating extraction barrel 1 is mixed in different directions, so that the heating is more uniform, and the extraction efficiency of the selenium is improved. The selenium is heated and evaporated by the heating extraction barrel 1 to perform the concentration work. When the heating extraction barrel 1 extracts the selenium, part of the selenium will adhere to the inner wall of the heating extraction barrel 1. The selenium needs to be cleaned. At this time, the rotating speed of the motor 412 is adjusted to the maximum. Under the action of the centrifugal force, the scraper 421 is swung towards the inner wall of the heating extraction barrel 1. The limiting block 419 fixedly installed at the end of the scraper 421 slides in the limiting groove 418, and the spring 420 is compressed. The scraper 421 rotates in close contact with the inner wall of the heating extraction barrel 1. The selenium adhering to the inner wall of the heating extraction barrel 1 is cleaned. When the rotating speed of the motor 412 is small, the limiting block 419 is reset and pushed under the elastic action of the spring 420. The scraper 421 slides away from the inner wall of the heating extraction barrel 1. The scraper 421 is shaken back and forth to avoid the selenium adhering to the outer wall of the scraper 421. The structure can stir the solution in the heating extraction barrel 1 in different directions, so that the heating is more uniform, and the extraction efficiency is improved. The scraper 421 can clean the selenium adhering to the inner wall of the heating extraction barrel 1 (the heating extraction barrel 1 is a known technology in the prior art, so the structure is not fully described).

[0029] Further, the rotating rod 423 is rotatably connected to the inner wall of the sleeve pipe 416. The outer wall of the sleeve pipe 416 is rotatably connected to the inner wall of the heating extraction barrel 1. The sleeve pipe 416 and the rotating rod 423 rotate in opposite directions under the limitation of the first bevel gear 414, the second bevel gear 415 and the third bevel gear 422. The solution in the heating extraction barrel 1 is mixed in different directions, so that the heating is more uniform.

[0030] Further, one end of the spring 420 is fixedly installed with the side wall of the limiting block 419, and the other end of the spring 420 is fixedly installed with the inner wall of the limiting groove 418, under the elastic effect of the spring 420, the scraper 421 subjected to a small centrifugal force is reset and pushed, reciprocation makes the scraper 421 vibrate, avoiding the selenium material adhered to the outer wall.
