However, after long-term use, impurities will accumulate at the sewage outlet, causing the sewage outlet to be blocked, thereby affecting the normal use of the sewage discharge device. In addition, traditional equipment is usually integrated, which makes it impossible to adjust the sewage flow rate and the sewage discharge volume of the sewage outlet cannot be adjusted according to the production needs of different medicines.

The inner wall of the frame 1 is slidably connected to the scraper 55, the outer wall of the fixed shaft 51 is slidably connected to the limiting frame 52, the inner wall of the connecting frame 2 is slidably connected to the valve ball 4, the outer wall of the fixed shaft 51 is fixedly connected to the outer wall of the connecting frame 7, the outer wall of the scraper 55 is fixedly connected to the end of the support frame 54 away from the sleeve 53, the outer wall of the limiting frame 52 is slidably connected to the inner wall of the connecting frame 2, and the outer wall of the limiting frame 52 is fixedly connected to the fixing ring 56.

[0022] The side of the fixing ring 56 away from the limit frame 52 is slidably connected to a sliding ball 57, and the sliding ball 57 is arranged in a ring along the central axis of the fixing ring 56. The outer wall of the sliding ball 57 contacts the outer wall of the shaft sleeve 53. The sliding ball 57 not only limits the position of the shaft sleeve 53, but also reduces the friction between the shaft sleeve 53 and the fixing ring 56. The inner wall of the fixing ring 56 is rotatably connected to the outer wall of the fixed shaft 51. The corners of the frame 1 are fixedly connected with a fixing plate 58, and the outer wall of the fixing plate 58 is fixedly connected with a top spring 59. The end of the top spring 59 away from the fixing plate 58 is fixedly connected to the limiting plate 510. The outer wall of the limiting plate 510 is slidably connected to the inner wall of the frame 1, and the outer wall of the limiting plate 510 contacts the outer wall of the limit frame 52.

[0023] The adjusting mechanism 6 includes a swivel 63, the bottom of the swivel 63 is fixedly connected to a spring plate 64, the bottom of the swivel 63 is fixedly connected to a connecting column 65, the outer wall of the connecting column 65 is slidably connected to the positioning frame 61, the outer wall of the positioning frame 61 is fixedly connected to the positioning plate 62, the top of the positioning plate 62 is slidably connected to the bottom of the spring plate 64, and the elastic potential energy is released by the spring plate 64, thereby pushing the positioning frame 61 to slide downward, the outer wall of the connecting column 65 is rotatably connected to the inner wall of the connecting frame 2, and the bottom of the connecting column 65 is fixedly connected to the top of the valve ball 4.

[0024] Working principle:

[0025] When in use, it is first necessary to connect the connecting pipe 3 on the connecting frame 2 to the evaporator, so that the sewage in the evaporator can enter the connecting frame 2 through the connecting pipe 3. The valve ball 4 is connected to the connecting frame 2 through the adjusting mechanism 6. Therefore, the valve ball 4 can be driven to rotate by rotating the adjusting mechanism 6, thereby changing the amount of sewage passing through the connecting frame 2. The sewage passing through the connecting frame 2 enters the frame 1 and hits the scraping mechanism 5, thereby driving the scraping mechanism 5 to rotate. During the rotation of the scraping mechanism 5, the scraper 55 on the scraping mechanism 5 scrapes the inner wall of the frame 1, thereby preventing substances in the sewage from accumulating in the frame 1, thereby affecting the normal operation of the sewage discharge device.

[0026] When it is necessary to adjust the discharge volume of sewage, the staff only needs to grab the positioning frame 61 on the swivel 63 and lift the positioning frame 61 upward to slide the positioning frame 61 out of the positioning groove on the connecting frame 2, thereby releasing the lock of the swivel 63. In the process of sliding upward, the positioning frame 61 synchronously squeezes the spring plate 64 on the positioning plate 62, so that the spring plate 64 accumulates elastic potential energy. After the positioning frame 61 releases the lock of the swivel 63, the swivel 63 can be rotated to synchronously drive the valve ball 4 to rotate through the connecting column 65, thereby changing the flow rate of sewage through the inside of the valve ball 4, and then changing the discharge volume of the sewage discharge device. After the position of the valve ball 4 is changed to the desired position, it is only necessary to release the pulling force on the positioning frame 61 to make the spring plate 64 release the elastic potential energy, thereby pushing the positioning frame 61 to slide back into the positioning groove, thereby locking the position of the swivel 63.

[0027] After the sewage enters the frame 1, the sewage will hit the scraper 55, and because the scraper 55 is arc-shaped, the scraper 55 rotates along the shaft sleeve 53, thereby scraping the inner wall of the frame 1, thereby preventing impurities in the sewage from accumulating in the frame 1. When the scraper 55 has been used for a long time and the scraper 55 has a poor cleaning effect due to wear, it is only necessary to slide the limit plates 510 at the corners of the frame 1 away from the frame 1 at the same time to release the lock on the limit frame 52, then slide the limit frame 52 out of the fixed shaft 51, and then grab the support frame 54 to remove the scraper 55. When installing a new scraper 55, it is only necessary to slide the shaft sleeve 53 along the fixed shaft 51 so that the shaft sleeve 53 rests on the connecting frame 7. Then, slide the fixing ring 56 on the limit frame 52 along the fixed shaft 51, and make the sliding ball 57 on the fixing ring 56 rest on the shaft sleeve 53. When the shaft sleeve 53 rotates, the sliding ball 57 rests on the shaft sleeve 53, thereby limiting the position of the shaft sleeve 53 and assisting the sliding of the shaft sleeve 53, reducing the wear of the shaft sleeve 53. After the limit frame 52 has completely slid into the frame 1, the force on the limit plate 510 can be released. Because the position of the fixing plate 58 was fixed when the limit plate 510 was slid, the top spring 59 was compressed, so that the top spring 59 accumulated elastic potential energy. Therefore, when the force on the limit plate 510 is released, the top spring 59 releases the elastic potential energy, thereby pushing the limit plate 510 to reset, and the position of the limit frame 52 can be locked again.
