Description

Technical Field

[0001] The invention relates to the technical field of ceramic processing, and in particular to a material feeding mechanism for anti-clogging ceramic processing. Background Art

[0002] Ceramic clay is also called green material. There are many kinds of ceramic products, and their performance requirements and raw materials used are different. According to the performance requirements of ceramic products and the characteristics of the raw materials, the ratio of each raw material is determined. Usually, the ceramic raw materials are processed through batching and certain processes.

[0003] The raw materials need to undergo processes such as crushing, screening, and mixing to meet the preparation requirements of ceramic clay. Crushing and screening are to ensure that the particle size distribution of the raw materials is uniform, and mixing is to evenly mix various raw materials together to form clay with specific properties. Ceramic production requires the raw materials to be turned into a mud-like substance through processes such as adding water, stirring, and crushing, and then carefully processed and treated to become flexible clay.

[0004] The mixed mud needs to be discharged to the next process. When the mixing kettle discharges mud at the discharge port for a long time, mud will accumulate on the inner wall of the discharge port. If this continues for a long time, the discharge port will be blocked, resulting in a slow discharge speed and reduced efficiency. Summary of the invention

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1 - 5 shown, a feeding mechanism for anti-blocking ceramic processing includes a stirring barrel 1. A discharge barrel 101 for feeding is connected to the bottom of the stirring barrel 1. A blocking plate 102 for blocking is arranged at the bottom of the discharge barrel 101. A cover plate 2 is detachably covered on the top of the stirring barrel 1. The feeding mechanism further includes a rotating cylinder 3 rotatably arranged on the cover plate 2. A stirring structure is arranged on the outer side of the rotating cylinder 3. The stirring structure includes a plurality of stirring blades 8. The stirring blades 8 are fixedly distributed on the outer side wall of the rotating cylinder 3. A driven wheel 4 is fixedly arranged at the top of the rotating cylinder 3. A driving structure for driving the driven wheel 4 to rotate is arranged on the top of the cover plate 2. A lifting rod 9 is movably inserted into the rotating cylinder 3. A clamping structure is further arranged between the rotating cylinder 3 and the lifting rod 9. A limiting rod 901 for limiting is arranged on the side of the lifting rod 9. The lifting rod 9 can slide up and down along the inner wall of the rotating cylinder 3. By using the limiting rod 901 for limiting, the lifting rod 9 can be driven to rotate while the rotating cylinder 3 rotates. The limiting rod 901 is slidably connected to the inside of the rotating cylinder 3. A moving structure for driving the lifting rod 9 to move up and down is arranged on the top of the cover plate 2. A scraping wall structure is further arranged in cooperation with the side of the lifting rod 9. A spiral conveyor blade 13 is arranged at the bottom of the lifting rod 9. The spiral conveyor blade 13 is located inside the discharge barrel 101. The upper end of the spiral conveyor blade 13 is higher than the upper edge of the discharge barrel 101, so that the spiral edges of the spiral conveyor blade 13 contact more slurry, and the slurry can be pushed out of the discharge barrel 101 more quickly. In actual use, during the stirring process, while the driving structure drives the rotating cylinder 3 to rotate, the lifting rod 9 drives the stirring blades 8 on the side to rotate synchronously to stir the slurry. During this process, the lifting rod 9 drives the spiral conveyor blade 13 at the bottom to rotate. The spiral conveyor blade 13 conveys the slurry accumulated inside the discharge barrel 101 upward, avoiding the blockage of the discharge caused by the slurry accumulating in the discharge barrel 101. During the discharging process, the rotating cylinder 3 is rotated in the reverse direction, and the slurry is pushed out of the discharge barrel 101 through the rotating spiral conveyor blade 13. By driving the lifting rod 9 and the spiral conveyor blade 13 to move up and down through the moving structure, the stirred slurry can be guided and discharged to prevent it from blocking the discharge barrel 101. Due to the continuous advancement of the spiral conveyor blade 13, the problem that the slurry is easily blocked in the discharge barrel 101 is effectively solved, eliminating the trouble of manual cleaning and greatly improving the working efficiency of slurry mixing.

[0030] In some specific implementation schemes, such as Figure 3As shown in the figure, in order to make the slurry discharge inside the stirring barrel 1 more complete, the stirring barrel 1 is in the shape of a bucket, and the diameter of the stirring barrel 1 gradually increases from the top to the bottom. The scraping structure includes a scraper 12. A number of through slots 10 are formed through the side wall of the rotating cylinder 3 along its height direction. A number of connecting rods 11 are connected to the side surface of the lifting rod 9. The connecting rods 11 penetrate through the corresponding through slots 10, and their ends are connected to the scraper 12. The connecting rods 11 can slide up and down along the through slots 10. The scraper 12 cooperates with the inner wall of the stirring barrel 1. During the stirring state, the scraper 12 is parallel to the inner wall of the stirring barrel 1 and has a certain distance from the inner wall of the stirring barrel 1. When the rotating cylinder 3 drives the scraper 12 to rotate, the scraper 12 can stir the slurry inside the stirring barrel 1, and the scraper 12 does not contact the inner wall of the stirring barrel 1, reducing the wear of the scraper 12. During discharging, the moving structure drives the lifting rod 9 and the scraper 12 to move down synchronously. The scraper 12 fits against the inner wall of the stirring barrel 1. When the lifting rod 9 drives the scraper 12 to rotate, the slurry adhered to the inner wall of the stirring barrel 1 is scraped off.

[0031] In some specific embodiments, as Figure 3 shown in the figure, in order to facilitate driving the rotation of the rotating cylinder 3, the driving structure includes a driving wheel 5. The driving wheel 5 is rotatably connected to the top of the cover plate 2. A motor 6 for driving the driving wheel 5 to rotate is fixedly provided on the top of the cover plate 2. A synchronous belt 7 is sleeved on the outside of the driven wheel 4 and the driving wheel 5. The motor 6 drives the driving wheel 5 to rotate. Through the cooperation of the synchronous belt 7, the driven wheel 4 drives the rotating cylinder 3 to rotate accordingly.

[0032] In some specific embodiments, as Figure 1 or Figure 3 shown in the figure, in order to facilitate driving the spiral conveyor blade 13 to move up and down, the moving structure includes a convex ring 14. A number of convex rings 14 are provided, and they are all vertically distributed on the outer side wall of the lifting rod 9. The adjacent convex rings 14 form grooves. A support frame 16 is fixedly connected to the top of the cover plate 2. A driving gear 15 is rotatably provided on the support frame 16. A motor 17 for driving the driving gear 15 to rotate is fixedly provided on the support frame 16. The teeth of the motor 17 are meshed with the corresponding grooves. Starting the motor 17 drives the driving gear 15 to rotate. The convex ring 14 meshed with the driving gear 15 drives the lifting rod 9 to move up and down, so as to be able to drive the spiral conveyor blade 13 to push the slurry at the bottom of the stirring barrel 1 into the discharge tube 101.

[0033] In some specific embodiments, as Figure 5As shown in the figure, in order to reduce the wear between the driving gear 15 and the convex ring 14 during stirring, the clamping structure includes a clamping groove 21. The clamping grooves 21 are formed in the inner side walls of both sides of the rotating cylinder 3. A T-shaped groove 18 communicating with the clamping groove 21 is arranged in the lifting rod 9. Two clamping blocks 22 are elastically arranged at both ends of the T-shaped groove 18. Pressing plates 25 are connected to both sides of each clamping block 22. A return spring 24 is arranged between the pressing plate 25 and the corresponding side wall of the T-shaped groove 18. One end of the clamping block 22 is adapted to the corresponding clamping groove 21, and the other end is connected with a spherical touch block 23. A driving member is movably inserted into the top of the lifting rod 9. The driving member is used to drive the two clamping blocks 22 to move. The driving member includes a T-shaped push rod 19. The T-shaped push rod 19 is inserted into the top of the lifting rod 9, and a triangular block 20 is connected to the bottom thereof. The triangular block 20 is movably located in the T-shaped groove 18. The triangular block 20 is an isosceles triangle. Both sides of the triangular block 20 are in contact with the spherical touch block 23. A tension spring 26 is arranged between the triangular block 20 and the T-shaped groove 18. A magnetic block 27 is arranged at the top of the lifting rod 9. The top of the T-shaped push rod 19 is made of iron material. During stirring, the T-shaped push rod 19 is pushed downward, the tension spring 26 is stretched, and the top of the T-shaped push rod 19 is adsorbed by the magnetic block 27, so that the T-shaped push rod 19 is fixed. The downward movement of the T-shaped push rod 19 drives the triangular block 20 to push the clamping blocks 22 to both sides and engage them into the corresponding clamping grooves 21. During the movement of the clamping blocks 22, the return spring 24 is compressed. At this time, the lifting rod 9 and the rotating cylinder 3 are relatively fixed, avoiding the up-and-down shaking of the lifting rod 9 from wearing the convex ring 14. During discharging, the T-shaped push rod 19 is lifted to release the fixation between the lifting rod 9 and the rotating cylinder 3. At this time, the lifting rod 9 can slide up and down in the rotating cylinder 3.

[0034] In some specific implementation manners, in order to facilitate the later cleaning of the inside of the stirring barrel 1, a water injection port is arranged at the top of the cover plate 2. Water is injected into the inside of the stirring barrel 1 from the water injection port, and the scraper 12 rotates to clean the inner wall of the stirring barrel 1.

[0035] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and should not be considered as limiting the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
