[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] Specific implementation examples are given below.
[0027] Please see Figures 1-5This utility model provides a dual-core rotary metering feeder valve, including a feeder valve housing. The feeder valve housing is provided with an upper chamber 1, a middle discharge chamber 2, and a lower chamber 3 arranged sequentially from top to bottom. The upper chamber 1, middle discharge chamber 2, and lower chamber 3 are integrally formed. By setting the upper chamber 1 and lower chamber 3, the unloading rate can be slowed down, thereby metering and discharging the material. A feed inlet flange 4 is provided above the upper chamber 1, which is connected to an external feeding device to discharge the material into the feeder valve housing. A lower feeder flange 5 is provided below the lower chamber 3, which is connected to an external downstream device to further discharge the unloaded material. Continuous conveying is provided. The upper cavity 1 and the lower cavity 3 are respectively equipped with a drive shaft 6. A sealing cover 7 is provided on one side of the upper cavity 1 and the lower cavity 3 to improve the sealing performance of the feed valve. A sealing bearing 8 is provided on the sealing cover 7. One end of the corresponding drive shaft 6 is connected to the sealing bearing 8. A cavity cover plate 9 is detachably provided on the other side of the upper cavity 1 and the lower cavity 3. The user can remove the cavity cover plate 9 from the corresponding upper cavity 1 and the lower cavity 3 to facilitate the later cleaning of the feed valve. A feeding component is provided in the drive shaft 6. A cleaning mechanism is provided on the feeding component to clean the inside of the feed valve during material conveying.
[0028] Furthermore, such as Figure 3 As shown, the feeding component includes a sleeve 10 mounted on the transmission main shaft 6. Multiple dividing plates 11 are evenly arranged around the sleeve 10. The number of dividing plates 11 is five, so that the sleeve 10 and the multiple dividing plates 11 form an impeller structure with an equal division structure. The impeller rotates in the upper cavity shell 1 and the lower cavity shell 3, thereby metering and discharging the material in the upper cavity shell 1 and the lower cavity shell 3 from the feeding valve shell.
[0029] Furthermore, such as Figure 3 and Figure 5 As shown, the cleaning mechanism includes an installation groove 12 on the outer end of the separating plate 11. A cleaning holder 13 is detachably installed on the installation groove 12. A set of cleaning brushes 14 and cleaning scrapers 15 are arranged in parallel on the cleaning holder 13. The cleaning scrapers 15 are located between the two cleaning brushes 14. The cleaning brushes 14 and cleaning scrapers 15 are in contact with the cavity walls of the corresponding upper cavity shell 1 and lower cavity shell 3. The brushes of the cleaning scrapers 15 are made of highly elastic nylon, and the cleaning scrapers 15 are made of nitrile rubber. The scraping surface of the cleaning scrapers 15 has a cutting edge. With this structure, the material attached to the cavity walls of the upper cavity shell 1 and lower cavity shell 3 can be effectively cleaned off.
[0030] Furthermore, such as Figure 3 and Figure 5As shown, a set of material shaking components are respectively arranged on the separating surface of the separating plate 11. The material shaking components include a sliding column 16 arranged on the separating plate 11, a material shaking ring 17 sleeved on the sliding column 16, and a circular cover plate 18 arranged on the outer end of the sliding column 16. The diameter of the circular cover plate 18 is larger than the inner diameter of the material shaking ring 17. When the separating plate 11 rotates, the material shaking ring 17 shakes on the sliding column 16. The circular cover plate 18 limits the material shaking ring 17. The material shaking ring 17 collides with the separating surface of the separating plate 11, causing the separating surface of the separating plate 11 to vibrate, thereby shaking off the attached material, thus facilitating the removal of the material from the separating plate 11.
[0031] Furthermore, such as Figure 5 As shown, the separating plate 11 has a cavity plate structure, which facilitates the shaking component to shake off the material attached to the separating surface of the separating plate 11, thereby making it easier to clean the material off the separating plate 11. The surface of the separating plate 11 is provided with a wear-resistant and non-stick nano coating, which improves the wear resistance of the separating plate 11 and reduces the material adhering to the surface of the separating plate 11.
[0032] Furthermore, such as Figure 1 and Figure 2 As shown, a grooved wheel 19 is provided on the outer end of the transmission main shaft 6, and a transmission belt 20 is provided on the two grooved wheels 19. A geared motor 21 is provided on the lower transmission main shaft 6. An anti-slip layer is provided on the inner side of the transmission belt 20. Through the operation of the geared motor 21, the transmission belt 20 drives the grooved wheel 19 to rotate, thereby causing the feeder to run in the corresponding upper cavity 1 and lower cavity 3, so that the material is discharged from the feed valve housing.
[0033] Working principle: By connecting an external feeding device to the feeding flange 4 of the upper cavity 1, the material is discharged into the feeding valve housing. The feeding valve lower flange 5 of the lower cavity 3 is connected to an external downstream device, thereby continuously conveying the unloaded material. By setting the upper cavity 1 and the lower cavity 3, the unloading rate can be reduced, thereby metering and discharging the material.
[0034] The cleaning mechanism's structure facilitates the user's removal of materials adhering to the walls of the upper and lower chambers 1 and 3. By installing the cleaning holder 13 onto the mounting groove 12 on the outer end of the corresponding dispensing plate 11, the cleaning brushes 14 and cleaning scrapers 15 are brought into contact with the corresponding walls of the upper and lower chambers 1 and 3. A set of cleaning brushes 14 and cleaning scrapers 15 are arranged parallel to each other on the cleaning holder 13, with the cleaning scrapers 15 positioned between two cleaning brushes 14. This structural arrangement controls the operation of the reduction motor 21, causing the transmission belt 20 to drive the pulley 19 to rotate, thus allowing the feeder to move within the corresponding upper and lower chambers 1 and 3. The cleaning mechanism effectively removes materials adhering to the walls of the upper and lower chambers 1 and 3.
[0035] When the dispensing plate 11 rotates, the shaking ring 17 shakes on the sliding column 16. The circular cover plate 18 limits the shaking ring 17. The shaking ring 17 collides with the dispensing surface of the dispensing plate 11, causing the dispensing surface of the dispensing plate 11 to vibrate, thereby shaking off the attached material, making it easier to clean the material off the dispensing plate 11. The dispensing plate 11 is designed with a cavity plate structure, which improves the effect of the shaking component in shaking off the material attached to the dispensing surface of the dispensing plate 11. In addition, the surface of the dispensing plate 11 is provided with a wear-resistant and non-stick nano-coating, which improves the wear resistance of the dispensing plate 11 and reduces the material adhering to the surface of the dispensing plate 11.
[0036] Users can also remove the cavity cover plate 9 from the corresponding upper cavity 1 and lower cavity 3 for later fine cleaning of the inside of the feed valve.
[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
