Description

Technical Field

[0001] This utility model relates to the field of purification and separation technology, and in particular to a purification and separation device for electronic chemicals. Background Technology

[0002] In order to improve the purity and optimize the performance of electronic chemicals during manufacturing and meet the needs of high-end manufacturing industries such as semiconductors and integrated circuits, it is necessary to purify and separate electronic chemicals during the manufacturing process. Therefore, purification and separation equipment is required for processing.

[0003] Most existing purification and separation devices directly mix electronic chemical solutions using a single stirring structure. During the stirring process, the electronic chemical solutions tend to adhere to the inner wall, resulting in incomplete reactions, reduced purification efficiency, and uneven mixing, which affects subsequent processing costs.

[0004] Therefore, to address the problem of uneven mixing caused by chemicals adhering to the inner wall during the above-mentioned electronic chemical purification and stirring process, an electronic chemical purification and separation device can be designed. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment of an electronic chemical purification and separation device, including a mixing tank 1 and a feeding hopper 2; it also includes a mixing component and a separation component. The mixing tank 1 is equipped with a mixing component for mixing solutions, and a separation component for separating electronic chemicals is installed at the bottom of the mixing tank 1. The feeding hopper 2 is located at the middle position of the top of the mixing tank 1. The mixing component includes a rotating rod 301, a mounting plate 302, and scrapers 303. The mixing tank 1 is equipped with a rotating rod 301 with a servo motor. The mounting plate 302 is symmetrically arranged on the outer side of the rotating rod 301. Multiple sets of scrapers 303 are rectangularly distributed near the inner wall of the mixing tank 1, and one side of the scrapers 303 abuts against the inner wall of the mixing tank 1.

[0023] Please see Figures 2-4 In this embodiment, a connecting rod 304 is installed on the inner wall end of the mounting plate 302 away from the mixing tank 1. A first bearing 305 is provided on the opposite side of the connecting rod 304, and the first bearing 305 is sleeved on the rotating rod 301. Two sets of second bearings 306 are sleeved on the outer side of the rotating rod 301, and the second bearings 306 are located below the first bearings 305. A stirring plate 307 is symmetrically arranged on the outer side of the second bearings 306, and a through hole is provided inside the stirring plate 307. A stirring rod 308 is symmetrically arranged on the outer side of the stirring plate 307. The solution in the mixing tank 1 is stirred by the rotation of the second bearings 306 and the stirring rod 308. At the same time, the through hole on the stirring plate 307 further assists the stirring rod 308 in stirring, increasing the degree of mixing and making it fully mixed.

[0024] Please see Figures 3-4In this embodiment, the separation assembly includes a separation box 401, a heating motor 402, a mounting groove 403, an attachment roller 404, a fixing plate 405, and a support rod 406. The separation box 401 is located at the bottom of the mixing tank 1, and an inlet pipe is provided between the separation box 401 and the mixing tank 1. The heating motor 402 is connected to the left side of the separation box 401, and two sets of mounting grooves 403 are opened opposite each other at the front end of the separation box 401. The attachment rollers 404 are slidably connected inside the mounting grooves 403, and the attachment rollers 404 are symmetrically arranged in the center. There are three sets; the front and rear ends of the attachment roller 404 are fixedly connected to the fixing plate 405, and the middle position of the front end of the fixing plate 405 is provided with a handle. The four corners of the bottom end of the separation box 401 are provided with support rods 406 with anti-slip pads. The solution in the separation box 401 is heated and evaporated by starting the heating motor 402. The evaporated solid crystals are attached to the attachment roller 404. When taking it out, the attachment roller 404 can be pulled out of the separation box 401 through the handle at the front end of the fixing plate 405, so as to collect and preserve the crystals.

[0025] Example 1

[0026] The second bearing 306 is mounted on the rotating rod 301. Electronic chemical raw materials and mixed reagents are poured into the mixing tank 1 through the feed hopper 2 according to the ratio. Under the operation of the motor inside the rotating rod 301, the rotating rod 301 rotates, thereby causing the second bearing 306 to drive the stirring rod 308 to rotate, stirring the solution in the mixing tank 1. At the same time, with the cooperation of the stirring plate 307, it makes more thorough contact with the liquid in the mixing tank 1, guiding the material to form a more complex flow pattern in the mixing tank, which helps the material to be mixed more evenly and avoids the accumulation and waste of material in the mixing tank. After mixing, the solution flows into the separation tank 401 through the connecting pipe connected to the separation tank 401. The heating motor 402 is started to heat and evaporate the solution in the separation tank 401. The evaporated solid crystals adhere to the attachment roller 404. When removing them, the attachment roller 404 can be pulled out of the separation tank 401 through the handle at the front end of the fixing plate 405, thereby collecting and storing the crystals.

[0027] Example 2

[0028] Both the second bearing 306 and the first bearing 305 are mounted on the rotating rod 301, so that one side of its scraper 303 abuts against the inner wall of the mixing tank 1. When the stirring rod 308 stirs the material in the mixing tank 1, the scraper 303 scrapes off the material adhering to the inner wall of the mixing tank 1, ensuring the uniformity and consistency of the material during the stirring process, avoiding the phenomenon of excessively high or low local material concentration, and promoting the circulation of the material in the mixing tank 1, further improving the stirring efficiency and effect. After mixing, the solution flows into the separation tank 401 through the connecting pipe connected to the separation tank 401 for crystallization separation.

[0029] During operation, electronic chemical raw materials and mixed reagents are poured into the mixing tank 1 through the feed hopper 2. The motor inside the rotating rod 301 rotates the rotating rod 301, thereby rotating the second bearing 306 and the stirring rod 308 to stir the solution in the mixing tank 1 and make it fully mixed. After mixing, the solution flows into the separation tank 401 through the connecting pipe connected to the separation tank 401. The heating motor 402 starts to heat and evaporate the solution in the separation tank 401. The evaporated solid crystals adhere to the attachment roller 404. When removing them, the attachment roller 404 can be pulled out of the separation tank 401 through the handle at the front end of the fixing plate 405, thereby collecting and storing the crystals. During the stirring process, the scraper 303 scrapes off the liquid adhering to the inner wall of the mixing tank 1 while the rotating rod 301 rotates, making the stirring more uniform and thus improving the mixing uniformity.

[0030] Through the above steps, with the cooperation of the mounting plate 302 and the scraper 303, when the chemical is purified and stirred, the chemicals adhering to the inner wall are scraped off and remixed into the main material, thereby avoiding local concentrations that are too high or too low, and improving the uniformity of mixing. At the same time, with the cooperation of the stirring rod 308 and the scraper 303, the swirling phenomenon of the liquid in the stirring container is reduced, and the stirred liquid is made to tumble up and down, achieving a more uniform mixing effect; thus solving the problem of uneven mixing caused by chemicals adhering to the inner wall during the purification and stirring of electronic chemicals.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
