Description

Technical Field

[0001] The present application relates to the technical field of chitosan powder processing, and in particular to a composite chitosan powder vibrating screen. Background Art

[0002] Composite chitosan powder is a powdery mixture composed of chitosan and other ingredients. Chitosan is a natural biopolymer material extracted from the shells of crustaceans (such as shrimps and crabs) and has a variety of excellent properties, including good biocompatibility, strong biodegradability, and excellent adsorption performance. The main purpose of vibrating and screening composite chitosan powder is to control its particle size and improve the uniformity of the product. Vibrating and screening can remove impurities and particles of uneven size in the particles, ensuring the stable quality of the product and meeting the specific particle size requirements;

[0003] In the utility model with the Chinese patent authorization announcement number "CN219112160U", "a composite chitosan powder vibrating screen is disclosed, comprising a shell, a cylindrical feed port is fixed on the top of the shell, a funnel-shaped discharge port is fixed on the bottom of the feed port, a screening assembly is installed in the middle of the inner wall of the shell, an electric lifting rod is fixed on one side of the top of the inner wall of the shell, and a lifting rod is fixed on the bottom end of the electric lifting rod. The composite chitosan powder vibrating screen drives the lifting and lowering of the lifting rod by the electric lifting rod, and drives the lifting and lowering of the vibrating hammer, so that the screening mesh plate can be intermittently pressed down, so that it can be vibrated and screened under the elastic expansion and contraction of the spring; the rotation of the rotating shaft is driven by the motor, and then the rotation of the connecting rod and the scraper is driven, so that the inner wall of the feed port can be effectively scraped, and at the same time, the lifting rod drives the rotating shaft, the connecting rod, the scraper and the conical component to move up and down, so that the material in the feed port can be pushed up and down to clear, thereby effectively preventing the material in the feed port from being blocked.";

[0004] With respect to the above-mentioned related technologies, the inventor believes that in the above-mentioned utility model, the electric lifting rod and the motor and other driving components are used to drive the vibrating hammer to press down the screening mesh plate to make it vibrate, and at the same time, the scraper is used to scrape the material on the inner wall of the feed port. First, the electric lifting rod drives the vibrating hammer to press down the screening mesh plate, and then the elastic effect of the spring is used to make the screening mesh plate vibrate. However, after the vibrating hammer presses down the screening mesh plate, it needs to gradually rise with the electric lifting rod, and the vibrating hammer is blocked above the screening mesh plate. Therefore, the spring may not be convenient to rebound quickly, which may cause the vibration amplitude of the screening mesh plate to be small, affecting its actual vibration screening effect. At the same time, when scraping the material on the inner wall of the feed port, it is also necessary to synchronously control the motor to rotate the scraper and other components, which is relatively cumbersome to operate.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0021] By adopting the above technical scheme, the feed pipe 2 on the screening box 1 can be used to pour the chitosan powder into the screening box 1, and the chitosan powder poured through the feed pipe 2 can directly enter the screening element, and can be synchronously output through the drive motor 3, at this time, the first gear 13 can be driven to rotate, thereby synchronously driving the ring gear 14 and the second gear 16 to rotate, through the rotation of the ring gear 14, the two sets of scrapers 15 fixedly connected at the bottom can be fitted to the inner wall of the feed pipe 2 and rotated, so that the residual material on the inner wall of the feed pipe 2 can be scraped off to avoid blockage and affect the feeding efficiency, etc. At the same time, while scraping, the rotation of the first gear 13 and the second gear 16 can drive the knocking piece provided at the bottom to knock on the screening element, so that the screening element is vibrated, thereby improving the screening effect of the chitosan powder.

[0022] Reference Figure 1 , Figure 2 and Figure 3, the screening member includes a fixed frame 5, a spring 6, a screening box 7 and a screening plate 8. The inner cavity side wall of the screening box 1 is fixedly connected with the fixed frame 5, and a plurality of groups of springs 6 are fixedly connected to the top of the fixed frame 5. The tops of the plurality of groups of springs 6 are fixedly connected to the screening box 7, and the inner cavity side wall of the screening box 7 is fixedly connected with the screening plate 8. The knocking member includes a sliding frame 9, a push-pull rod 10, an L-shaped sliding rod 11 and a rubber ball 12. The bottoms of the first gear 13 and the second gear 16 are both rotatably connected to the push-pull rod 10 through a rotating shaft. The ends of the two groups of push-pull rods 10, which are respectively away from the first gear 13 and the second gear 16, are rotatably connected to the L-shaped sliding rod 11 through a rotating shaft. The surfaces of the two groups of L-shaped sliding rods 11 are slidably connected to the sliding frame 9. The tops of the two groups of sliding frames 9 are fixedly connected to the inner cavity top of the screening box 1 by bolts. The bottoms of the two groups of L-shaped sliding rods 11 are fixedly connected to the rubber balls 12. A feeding port 4 is provided at the bottom of the screening box 1.

[0023] By adopting the above technical scheme, when the first gear 13 and the second gear 16 rotate, and at the same time, because the L-shaped sliding rod 11 is limited by the sliding frame 9, the push-pull rod 10 at the bottom of the first gear 13 and the second gear 16 can drive the L-shaped sliding rod 11 to repeatedly do linear reciprocating motion in the sliding frame 9, so that the rubber ball 12 can be reused to knock on both sides of the screening box 7. Since the screening box 7 is fixed by the spring 6 at the top of the fixing frame 5, during the knocking process, the screening box 7 and the sieve plate 8 in the screening box 7 can be vibrated synchronously through the knocking and the elastic effect of the elasticity, thereby improving the screening effect of the chitosan powder, and the screened chitosan powder material can be discharged centrally through the discharge port 4 opened at the bottom.

[0024] The implementation principle of a composite chitosan powder vibrating screen according to the embodiment of the present application is as follows: the chitosan powder can be poured into the screening box 1 through the feed pipe 2 on the screening box 1, and the chitosan powder can be poured into the screening element directly through the feed pipe 2, and can be output synchronously through the drive motor 3, at which time the first gear 13 can be driven to rotate, thereby synchronously driving the ring gear 14 and the second gear 16 to rotate, and through the rotation of the ring gear 14, the two sets of scrapers 15 fixedly connected at the bottom can be attached to the feed pipe 2 The inner wall of the feeding tube 2 is rotated, so that the residual material on the inner wall of the feeding tube 2 can be scraped off to avoid clogging and affect the feeding efficiency. At the same time, the first gear 13 and the second gear 16 rotate while scraping the material. At the same time, because the L-shaped sliding rod 11 is limited by the sliding frame 9, the push-pull rod 10 at the bottom of the first gear 13 and the second gear 16 can drive the L-shaped sliding rod 11 to repeatedly do linear reciprocating motion in the sliding frame 9, so that the rubber ball 12 can be repeatedly used to knock on both sides of the screening box 7. The separation box 7 is fixed by the spring 6 on the top of the fixing frame 5, so during the knocking process, the sieving box 7 and the sieve plate 8 in the sieving box 7 can be vibrated synchronously by knocking and the elastic effect of the elasticity, so that the screening effect of the chitosan powder can be improved, and the sieved chitosan powder material can be discharged centrally through the discharge port 4 opened at the bottom. The above-mentioned drive motor 3 can use a NEMA17 stepper motor, which is a synchronous motor. The movement of the rotor is controlled by applying a pulse signal. The stepper motor controller is an electronic product that can emit a uniform pulse signal. After the signal it emits enters the stepper motor driver, it will be converted by the driver into a strong current signal required by the stepper motor to drive the stepper motor to operate. The scraping of the inner wall of the feed pipe 2 and the knocking vibration of the sieve plate 8 can be completed by controlling the drive motor 3, and the vibration of the screening element and the scraping of the inner wall of the feed pipe 2 are linked. The operation is simpler and easier to use. While scraping, the screening element can be repeatedly knocked to vibrate it, thereby effectively improving the screening effect of the material.
