[0030] Specifically, the bottom end of the top cover 1 is rotatably connected to the extraction tank 2, and a water spray pipe 4 is provided inside the cavity of the extraction tank 2. A cavity is opened inside the water spray pipe 4, and a sliding rod 401 is slidably connected inside the cavity of the water spray pipe 4. Both the water spray pipe 4 and the sliding rod 401 are provided with round holes, and a cavity is opened inside the sliding rod 401. A first rotating rod 402 is rotatably connected inside the cavity of the sliding rod 401, and a second rotating rod 403 is rotatably connected to the outer side of the first rotating rod 402. A clamp 404 is fixed to the outer side of the second rotating rod 403 by threaded bolts, and a slide groove is opened inside the clamp 404. When in use, a scraper 405 is slidably connected inside the slide groove of the clamp 404, and the scraper 405 is used to scrape the inside of the extraction tank 2.

[0031] Furthermore, a square groove is provided inside the collecting tank 5, and a support plate 504 is fixedly connected inside the square groove of the collecting tank 5. A sliding groove is provided at the top of the support plate 504, and the support plate 504 is used for support.

[0032] Furthermore, a clamping plate 502 is slidably connected inside the slide groove of the support plate 504, a jack 503 is fixedly connected to the left side of the clamping plate 502, a filter plate 501 is tightly arranged on the outer side of the jack 503, the filter plate 501 slides inside the square groove of the collecting tank 5, and the filter plate 501 is pressed by the cooperation of the jack 503 and the clamping plate 502, so as to facilitate the separation of solid and liquid.

[0033] It is worth noting that a circular hole is opened on the front side of the collecting tank 5, and a drainage pipe 6 is tightly arranged inside the circular hole of the collecting tank 5. By draining the sewage from the drainage pipe 6, it is convenient to collect the sewage.

[0034] It is worth noting that a protective plate 202 is fixedly connected to the top of the top cover 1, and the end of the main shaft of the protective plate 202 is rotatably connected to the top of the feed port 201, so that the material is placed inside the protective plate 202 to rotate.

[0035] It is worth mentioning that a clamping plate 3 is provided at the bottom end of the cavity of the top cover 1. The bottom end of the clamping plate 3 is welded to a fixing rod 301, and a spring 302 is sleeved on the outer side of the fixing rod 301. The clamping plate 3 slides downward and enters the extrusion spring 302 to press downward.

[0036] It is worth emphasizing that a clamping ring 303 is tightly set at the bottom end of the spring 302, and a threaded rod 304 is fixedly connected to the bottom end of the fixing rod 301. The threaded rod 304 passes through the bottom end of the top cover 1 and is rotatably connected to the top cover 1. The threaded rod 304 is rotated to pull the fixing rod 301 downward, and then the clamping plate 3 slides downward to squeeze the spring 302 to form solid impurities into blocks.

[0037] Among them, the motor 101 is a prior art and will not be described in detail;

[0038] Working principle:

[0039] First, the staff introduces nicotinic acid from the inside of the feed port 201 at the top of the top cover 1, and then starts the motor 101. The end of the main shaft of the motor 101 drives the extension rod 203 to rotate. At this time, nicotinic acid enters from the feed port 201 and is discharged to the inside of the protective plate 202. At this time, the high-speed rotating centrifugal rod 207 separates the nicotinic acid into solid and liquid. At this time, the solid impurities are thrown into the inside of the filter element 204. At this time, the liquid is discharged from the hollow inside of the outer side of the filter element 204 and thrown to the inner wall of the cavity of the extraction tank 2.

[0040] At this time, the water spray pipe 4 drives the internal sliding rod 401 to extend downward, and the pressure inside the water spray pipe 4 is increased. At this time, clean water is discharged from the inside of the water spray pipe 4, and the solid impurities attached to the inner wall of the cavity of the extraction tank 2 are infiltrated and wetted. At this time, the first rotating rod 402 inside the sliding rod 401 is pulled out. At this time, the first rotating rod 402 drives the second rotating rod 403 to approach the direction of the solid impurities. At this time, the internal scraper 405 of the clamp 404 scrapes the inside of the extraction tank 2 and then cleans it. At this time, the fallen solid impurities fall into the bottom end of the clamping plate 3, and the threaded rod 304 rotates and tightens the fixing rod 301 downward, and then the clamping plate 3 slides downward to squeeze the spring 302 to block the solid impurities, which is convenient for later cleaning.

[0041] Finally, the discharged liquid flows to the inside of the collecting tank 5, and the pressing plate 502 slides in the direction of the filter plate 501 in the slide groove of the supporting plate 504. At this time, the pressing plate 502 cooperates with the jack 503 to press against the filter plate 501, thereby squeezing out tiny solid and liquid impurities. At this time, the liquid is discharged from the inside of the drain pipe 6, thereby completing the collection of chloronicotinic acid.
