Description

Technical Field

[0001] This utility model relates to the field of feeding technology, specifically a vacuum feeding and dehydration device for feed additives. Background Technology

[0002] In the feed additive production industry, the processing flow of feed additives has strict requirements on the state of raw materials. Among them, dehydration is an indispensable key step before vacuum feeding. This is because if feed additives (whether in powder, granular, or paste form) contain too much moisture, the moisture will cause the raw materials to clump together, clogging the pipes, valves, and other components of the vacuum feeder. This not only requires frequent shutdowns for cleaning but can also damage the equipment and affect production continuity in severe cases. On the other hand, feed additives with excessive moisture content are prone to the growth of mold, bacteria, and other microorganisms during subsequent storage and use, leading to product spoilage. As the core equipment in the dehydration process, the drying device's feeding stability directly determines the operating status of the vacuum feeder. The two must form an efficient and coordinated production chain to meet the needs of large-scale feed additive production. However, most existing drying equipment used for feed additive production cannot continuously supply material to the vacuum feeder and adopts an intermittent feeding method. This intermittent feeding method has brought multiple negative impacts: First, the vacuum feeder is in a long-term intermittent state due to frequent waiting for material supply, resulting in reduced equipment utilization. Second, the discontinuity of material supply causes drastic fluctuations in the conveying capacity of the vacuum feeder. When the drying device unloads material, a large amount of dry material rushes into the feeder instantly, which can easily cause the raw material flow rate in the pipeline to be too fast, leading to "choking" blockage.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0004] In view of the problems existing in the above and / or existing vacuum feeding and dehydration devices for feed additives, this utility model is proposed.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Example 1 Please see Figures 1-5 This utility model provides a technical solution: A vacuum feeding and dehydration device for feed additives can achieve continuous drying and stable feeding of feed additives, avoid intermittent operation or choking of vacuum feeders, and improve production continuity and product quality consistency.

[0019] The vacuum feeding and dehydration device for feed additives includes a first frame 1 and a second frame 4, both of which are metal frames. They are used to support the vacuum feeding mechanism 2 and the dehydration conveying mechanism 5, respectively. The vacuum feeding mechanism 2 is fixed to the first frame 1 by bolts and is used to convey the dried feed additives to the subsequent process. An inlet pipe 3 is connected to the vacuum feeding mechanism 2. The other end of the inlet pipe 3 is connected to the discharge port 8 of the dehydration conveying mechanism 5 and is used to receive the dried raw materials. The dehydration conveying mechanism 5 is installed on the second frame 4 through a mounting shaft 14. The dehydration conveying mechanism 5 includes a cylinder 6, which is a cylindrical metal cylinder. The two ends are respectively provided with an inlet 7 and a discharge port 8. The inlet 7 is used to put in the feed additives to be dehydrated, and the discharge port 8 is used to discharge the dried raw materials.

[0020] A feeding plate 13 is rotatably mounted inside the cylinder 6 via bearings. A first motor 10 is fixed to one end of the cylinder 6 via bolts. The output end of the first motor 10 is connected to the feeding plate 13 via a coupling, providing power for the rotation of the feeding plate 13. A cover 19 is fixed to the top of the cylinder 6 via bolts. Evenly distributed air supply pipes 12 are inserted inside the cover 19. All air supply pipes 12 are connected to the air supply port of an external hot air blower. Hot air generated by the hot air blower enters the cylinder 6 through the air supply pipes 12 to dry the raw materials. The feeding plate 13 includes a transmission rod 15 rotatably mounted inside the cylinder 6 and connected to the output end of the first motor 10. A spiral plate 17 is welded to the outer wall of the transmission rod 15. The spiral plate 17 is used to drive the raw materials to move axially along the cylinder 6. Evenly distributed flip plates 16 are also welded to the outer wall of the transmission rod 15. The flip plates 16 are arc-shaped metal plates used to flip the raw materials and improve the uniformity of drying.

[0021] The first motor 10 drives the transmission rod 15 to rotate the spiral plate 17. The spiral plate 17 pushes the raw material along the cylinder 6 from the feed port 7 to the discharge port 8, realizing continuous conveying of the raw material. An external hot air blower continuously inputs hot air into the cylinder 6 through the air supply pipe 12 to dry the raw material during the movement. The transmission rod 15 drives the flip plate 16 to rotate synchronously. The flip plate 16 flips the raw material, breaks up the raw material clumps, increases the contact area between the raw material and the hot air, improves the uniformity and efficiency of drying, and avoids the local raw material from having excessive moisture content due to insufficient contact with the hot air. The dried raw material continuously enters the vacuum feeding mechanism 2 through the discharge port 8 and the inlet pipe 3, so that the vacuum feeding mechanism 2 can work continuously and stably, avoiding intermittent operation or choking, and ensuring the continuity of raw material supply for subsequent processes.

[0022] When in use, first start the external hot air blower and the first motor 10. The hot air generated by the hot air blower is continuously delivered to the cylinder 6 through the air supply pipe 12, so that the temperature inside the cylinder 6 rises to a suitable drying temperature. At the same time, the first motor 10 drives the transmission rod 15 to rotate, and the transmission rod 15 drives the spiral plate 17 and the flip plate 16 to rotate synchronously. The feed additives to be dehydrated are continuously fed into the cylinder 6 through the feed inlet 7. After the raw materials fall into the cylinder 6, they move axially towards the discharge port 8 under the push of the spiral plate 17. During the movement, the flip plate 16 continuously flips the raw materials, so that the raw materials are in full contact with the hot air conveyed by the air pipe 12. The moisture in the raw materials is carried away by the hot air, achieving dehydration and drying. The dried raw materials are continuously fed into the inlet pipe 3 of the vacuum feeding mechanism 2 through the discharge port 8. The vacuum feeding mechanism 2 is started, and the dried raw materials are stably conveyed to the subsequent mixing and other processes. Throughout the process, the feed inlet 7 continuously feeds the raw materials, the feeding plate 13 continuously conveys and flips the raw materials, the hot air is continuously supplied, and the discharge port 8 continuously discharges the dried raw materials, realizing continuous feeding of the vacuum feeding mechanism 2.

[0023] Example 2 Please see Figures 1-5 This utility model provides a technical solution: Based on Example 1, a moisture-absorbing and anti-contamination structure was added to further improve the drying effect of the raw materials, prevent the raw materials from adhering to the moisture-absorbing components, and ensure the purity of the raw materials after drying.

[0024] The cylinder 6 is symmetrically provided with mounting rollers 9 on both sides. The mounting rollers 9 are rotatably mounted on the second frame 4 through the bracket. One side of one of the mounting rollers 9 is fixed with a second motor 11 by bolts. The output end of the second motor 11 is connected to the mounting roller 9 through a coupling to provide power for the rotation of the mounting roller 9.

[0025] The same roll of absorbent cotton cloth 18 is sleeved between the mounting rollers 9. The absorbent cotton cloth 18 is a highly absorbent fabric, inserted into the mounting rollers 9 and slidably installed to absorb the moisture generated during the drying of the raw materials in the cylinder 6. Several pressure blocks 20 are fixed to the bottom surface of the cover 19 by bolts. The pressure blocks 20 are rubber blocks that abut against the absorbent cotton cloth 18, so that the absorbent cotton cloth 18 fits tightly against the inner wall of the top of the cylinder 6, thereby improving the moisture absorption effect.

[0026] The cylinder 6 is provided with a first partition 21 and a second partition 22. Both the first partition 21 and the second partition 22 are metal filter screens, located on both sides below the absorbent cotton cloth 18, to prevent the feed additives that are turned over from coming into contact with and adhering to the absorbent cotton cloth 18.

[0027] Unlike Example 1, the absorbent cotton cloth 18 can actively absorb moisture inside the cylinder 6, further reducing the moisture content of the raw materials and improving the drying effect. At the same time, the second motor 11 drives the installation roller 9 to rotate, which can replace the dry part of the absorbent cotton cloth 18 to ensure continuous moisture absorption. The first partition 21 and the second partition 22 prevent the raw materials from contaminating the absorbent cotton cloth 18.

[0028] Part of the moisture generated during the drying of raw materials inside the cylinder 6 is discharged with the airflow, while the other part is absorbed by the moisture-absorbing cotton cloth 18, keeping the humidity inside the cylinder 6 at a low level and further improving the drying effect of the raw materials. As the usage time increases, the part of the moisture-absorbing cotton cloth 18 in contact with the raw materials gradually becomes saturated. The second motor 11 is started, and the second motor 11 drives the mounting roller 9 to rotate. The mounting roller 9 moves the moisture-absorbing cotton cloth 18, winding the saturated moisture-absorbing cotton cloth 18 onto one side of the mounting roller 9. At the same time, the unused dry moisture-absorbing cotton cloth 18 on the other side of the mounting roller 9 is pulled into the cylinder 6 to continue absorbing moisture and ensure a continuous moisture absorption effect. The first partition 21 and the second partition 22 block the raw materials that are turned over by the flip plate 16, preventing the raw materials from directly contacting the moisture-absorbing cotton cloth 18 and preventing the raw materials from adhering to the moisture-absorbing cotton cloth 18, causing waste or pollution.

[0029] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
