Description

Technical Field

[0001] The utility model relates to the technical field of extractors, in particular to an extractor with an anti-adhesion inner wall. Background Art

[0002] Agitation is a crucial step in the extraction of diacetone acrylamide. Agitation helps improve extraction efficiency by thoroughly mixing the raw material and solvent, thereby accelerating the dissolution and separation of the target component. Organic solvents (such as methanol, ethanol, and acetone) are typically used as extractants in diacetone acrylamide extraction. The raw material and the organic solvent are mixed and then stirred. If the diacetone acrylamide adheres to the inner wall of the agitator during agitation, it can affect the stirring effect, complicate cleaning of the extraction cartridge, and even pose a safety hazard. Prolonged exposure of diacetone acrylamide to air or other oxidants can lead to unexpected reactions, posing safety risks.

[0003] Existing extractors generally use a scraper linked to a stirring device, so that the stirring device drives the scraper to scrape off the material adhering to the inner wall of the extractor. However, due to the precision of parts processing and inevitable errors during assembly, it is impossible for the scraper to completely fit the inner wall of the extractor. In addition, as the scraper gradually wears due to friction between the scraper and the inner wall of the extraction tube, the gap between the scraper and the extraction tube will gradually increase. The existing device cannot automatically compensate for the increased gap. Therefore, the existing scraper is not ideal for scraping off the adhesion on the inner wall of the extraction tube. Summary of the Invention

[0004] The purpose of the utility model is to solve the problems existing in the background technology and to propose an extractor with anti-sticking inner wall, which can make the scraper fit completely with the inner wall of the extraction cylinder and automatically compensate for the gap caused by the wear of the scraper.

[0006] a centrifugal compensating component comprising a plurality of scrapers slidably mounted on the stirring mechanism, and further comprising a limit assembly for controlling the unidirectional sliding of the scrapers.

[0007] An auxiliary cleaning component is installed on the centrifugal compensation component, and the auxiliary cleaning component drives the scraper to vibrate.

[0008] Optionally, the stirring mechanism includes a motor fixedly mounted on the top of the extraction cylinder, a rotating shaft rotatably mounted in the extraction cylinder, and a spiral blade fixedly mounted on the rotating shaft, and the rotating shaft is fixedly connected to the output shaft of the motor.

[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments. Example

[0024] like Figures 1 to 3 As shown, the present invention proposes an extractor with anti-adhesion inner wall, comprising an extraction cylinder 1, a feed port 101 fixedly mounted on the top of the extraction cylinder 1, a support base 2 fixedly mounted on the bottom of the extraction cylinder 1, and a discharge port 102 fixedly mounted on the bottom of the extraction cylinder 1. The material is put into the extraction cylinder 1 from the feed port 101, and can be discharged through the discharge port 102 after stirring. A valve is provided on the discharge port 102, and whether the material can flow out can be controlled by opening and closing the valve. It also includes a stirring mechanism rotatably mounted in the extraction cylinder 1, and the stirring mechanism includes a motor 3 fixedly mounted on the top of the extraction cylinder 1, a rotating shaft 301 rotatably mounted in the extraction cylinder 1, and a spiral blade 302 fixedly mounted on the rotating shaft 301, and the rotating shaft 301 is fixedly connected to the output shaft of the motor 3. After the material is placed in the extraction cylinder 1, the motor 3 can be started to drive the rotating shaft 301 to rotate, and then drive the spiral blades 302 to rotate. The spiral blades 302 stir and mix the material in the extraction cylinder 1, helping to improve the extraction efficiency and fully mix the raw materials and solvent, thereby accelerating the dissolution and separation of the target components.

[0025] like Figures 2 to 5As shown, this embodiment further includes a centrifugal compensation component, which includes a plurality of scrapers 403 slidably mounted on the stirring mechanism. The centrifugal compensation component also includes a limit assembly that controls the unidirectional sliding of the scrapers 403. When the scrapers 403 rotate with the rotating shaft 301, the scrapers will move toward the inner wall of the extraction cylinder 1 under the action of centrifugal force, so that the scrapers 403 can abut against the inner wall of the extraction cylinder 1. The rotating scrapers 403 scrape off the diacetone acrylamide adhering to the inner wall of the extraction cylinder 1, thereby preventing the stirring effect from being affected and effectively reducing the difficulty of cleaning the extraction cylinder 1.

[0026] Multiple sets of connecting plates 4 are fixedly mounted on the rotating shaft 301. Vertical plates 401 are mounted between the same set of connecting plates 4. Multiple compensating rods 402 are slidably mounted on the vertical plates 401. Scrapers 403 are fixedly mounted on the multiple compensating rods 402 located on the same vertical plate 401. The vertical plate 401 is provided with multiple sliding grooves 404, which correspond one-to-one with and are slidably connected to the compensating rods 402. When the rotating shaft 301 rotates, the multiple sets of connecting plates 4 rotate, which in turn, via the vertical plates 401, drives the multiple compensating rods 402 to rotate, thereby causing the multiple scrapers 403 to rotate with the rotation of the rotating shaft 301. The scrapers 403 are slidably connected to the vertical plates 401, and centrifugal force drives the scrapers 403 toward the inner wall of the extraction cylinder 1, thereby automatically compensating for the gap between the scrapers 403 and the inner wall of the extraction cylinder 1, thereby ensuring a scraping effect on the interior of the extraction cylinder 1.

[0027] Furthermore, the limiting assembly includes a limiting rod 5 slidably mounted within a chute 404. A plurality of limiting cylinders 501 are fixedly mounted on the vertical plate 401. The limiting cylinders 501 correspond to and are slidably connected to the limiting rods 5. A plugging head 504 is fixedly mounted on the limiting rod 5 and is located within the limiting cylinder 501. A one-way valve 502 is fixedly mounted on the limiting cylinder 501. A liquid reservoir 503 is fixedly mounted on the one-way valve 502. A pressure plate 505 is slidably mounted within the liquid reservoir 503. A spring 506 is fixedly mounted on the pressure plate 505. The other end of the spring 506 is fixedly connected to the inner wall of the liquid reservoir 503. The liquid reservoir 503, located below the pressure plate 505, within the limiting cylinder 501 and on one side of the plugging head 504, and within the one-way valve 502, are all filled with hydraulic medium. The one-way valve 502 allows the hydraulic medium inside the liquid storage tank 503 to enter the interior of the limiting cylinder 501. The hydraulic medium can be hydraulic oil or pure water. When the scraper 403 moves toward the inner wall of the extraction cylinder 1, it can drive the limiting rod 5 to move. The movement of the limiting rod 5 will increase the space on the right side of the limiting cylinder 501 and the plugging head 504. At this time, under the action of the spring 506, the pressure plate 505 is driven to press the hydraulic medium inside the liquid storage tank 503 into the limiting cylinder 501, so that the limiting cylinder 501 and the plugging head 504 are located at the right side of the limiting cylinder 501. The right side of 04 is always filled with hydraulic medium. At this time, when the scraper 403 is moved away from the inner wall of the extraction cylinder 1 due to resistance, the blocking head 504 will be driven to move to the right through the limiting rod 5, and the hydraulic medium inside the limiting cylinder 501 needs to be compressed, thereby effectively preventing the scraper 403 from moving away from the extraction cylinder 1, ensuring that the scraper 403 can overcome the resistance, ensuring the stability of the combination of the scraper 403 and the inner wall of the extraction cylinder 1, and thus ensuring the effect of scraping the inner wall of the extraction cylinder 1.

[0028] like Figure 6 As shown, this embodiment also includes an auxiliary cleaning assembly mounted on the centrifugal compensation component, which drives the scraper 403 to vibrate. The auxiliary cleaning assembly includes an arcuate groove 6 provided on the upper connecting plate 4. The center of the arcuate groove 6 is located on the axis of the rotating shaft 301. A connecting shaft 601 is slidably mounted within the arcuate groove 6, ensuring that the scraper 403 always maintains contact with the inner wall of the extraction cylinder 1 as it slides along the arcuate groove 6. One end of the connecting shaft 601 is fixedly connected to the scraper 403. A push rod motor 602 is rotatably mounted on the connecting plate 4 provided with the arcuate groove 6. The output shaft of the push rod motor 602 is rotatably connected to the connecting shaft 601. By starting the push rod motor 602 and making it reciprocate and extend, the connecting shaft 601 can be driven to move back and forth inside the arc groove 6, thereby driving the scraper 403 to vibrate, thereby preventing the scraper 403 from sticking to the material, and vibrating the material around the inside of the extraction cylinder 1 to prevent the material from sticking to the inner wall of the extraction cylinder 1, which can effectively improve the overall cleaning effect of the device.

[0029] Working principle: Put the material into the extraction cylinder 1 from the feed port 101, start the motor 3 to drive the rotating shaft 301 to rotate, and then drive the spiral blade 302 to rotate. The spiral blade 302 stirs and mixes the material in the extraction cylinder 1, helping to improve the extraction efficiency, fully mix the raw materials and solvent, and thus accelerate the dissolution and separation of the target components.

[0030] As the scraper 403 rotates with the shaft 301, it is centrifugally driven to move toward the inner wall of the extraction cylinder 1. This allows the scraper 403 to abut against the inner wall of the extraction cylinder 1 and scrape off diacetone acrylamide adhering to the inner wall of the extraction cylinder 1 through the rotating scraper 403, thereby preventing the mixing effect from being affected and effectively reducing the difficulty of cleaning the extraction cylinder 1. The one-way valve 502 allows the hydraulic medium in the liquid storage tank 503 to enter the limiting cylinder 501. When the scraper 403 is resisted and moves away from the inner wall of the extraction cylinder 1, the limiting rod 5 drives the plug 504 to move rightward, compressing the hydraulic medium in the limiting cylinder 501. This effectively prevents the scraper 403 from moving away from the extraction cylinder 1, ensuring that the scraper 403 can overcome the resistance and maintain the stability of the scraper 403's connection with the inner wall of the extraction cylinder 1, thereby ensuring the scraping effect of the inner wall of the extraction cylinder 1.

[0031] The above specific embodiments are merely several optional embodiments of the present invention.
