Description

Technical Field

[0001] The utility model relates to the technical field of biological feed production, in particular to a biological feed drying device. Background Technique

[0002] Biological feed refers to the general term of feed products developed by bioengineering technologies such as fermentation engineering, enzyme engineering, protein engineering, and genetic engineering using feed raw materials and additives permitted by relevant national regulations. During the processing of biological feed, the raw materials are first crushed, then mixed, the mixed raw materials are fermented, dried after fermentation is completed, and finally formulated into finished products to obtain biological feed.

[0003] The existing document with the publication number CN219640599U discloses a biological feed drying device, which includes a tank body. A first rotating rod is rotatably inserted into the inner wall of the tank body. A scraping blade is fixedly sleeved on the outer side of the first rotating rod and is distributed in a path array. A first cavity is opened in the tank body. Partition plates are fixedly arranged on the inner wall of the tank body in a staggered manner and are distributed in a path array. A second cavity is opened in the partition plate; by setting the first rotating rod, partition plates, first cavity, second cavity, and scraping blades, the feed in the tank body can be continuously and efficiently dried. By setting a material guiding box, a feeding pipe, a second rotating rod, a spiral blade, etc., the dried feed can be conveyed out, avoiding the problem of inconvenient transmission, so as to achieve the purpose of convenient transmission.

[0004] However, this solution still has deficiencies. During actual use, after hot air enters the first cavity, it heats the inside of the tank body. Since the first cavity does not directly contact the feed but conducts heat through an air medium, it will lead to problems such as low drying efficiency, waste of hot air, low thermal energy utilization rate, and large loss, thereby increasing the cost of feed production and drying.

[0005] Therefore, it is necessary to provide a biological feed drying device to solve the above technical problems. Content of the Utility Model

[0022] Please refer to Figures 1 - 3, the present utility model provides an embodiment: a biological feed drying device, including a base 1, on which a spiral feeding device 4 is provided. The spiral feeding device 4 includes a primary spiral and a secondary spiral. The primary spiral includes a spiral turntable 41, with an outer baffle 43 provided on the outer side of the spiral turntable 41 and an inner baffle 44 provided on the inner side of the spiral turntable 41. Both the outer baffle 43 and the inner baffle 44 are of spiral structure. A partition plate 42 is connected between the outer baffle 43 and the inner baffle 44, and the partition plate 42 is also of spiral structure. The partition plate 42 divides the spiral turntable 41 into upper and lower layers. An air inlet pipe 7 is provided above the spiral turntable 41, and an air outlet pipe 8 is provided below the spiral turntable 41. One ends of both the air inlet pipe 7 and the air outlet pipe 8 are hermetically connected to the lower layer of the spiral turntable 41; the secondary spiral includes a spiral discharge chute 9, and the spiral discharge chute 9 is connected to the bottom of the spiral turntable 41.

[0023] In this device, the spiral turntable 41 forms an inclination angle longitudinally by itself, and the inclination angle in the transverse direction is 10° - 20°, that is, the side of the partition plate 42 close to the center is inclined downward by 10° - 20°; the air inlet of the air inlet pipe 7 is larger than that of the air outlet pipe 8, thereby forming an air flow displacement difference. The lower layer of the spiral turntable 41 is more easily filled with hot air, thus quickly raising the overall temperature of the device and facilitating subsequent drying production.

[0024] Furthermore, an outer cover 2 is sleeved outside the spiral feeding device 4. The outer cover 2 is movably connected to the base 1. A feed hopper 3 is provided at the top of the outer cover 2. The ends of both the air inlet pipe 7 and the air outlet pipe 8 far from the spiral feeding device 4 extend outside the outer cover 2. A discharge pipe 10 is provided through the bottom of the outer cover 2. The end of the discharge pipe 10 inside the outer cover 2 is connected to the spiral discharge chute 9. The outer cover 2 can improve the internal heat preservation effect and facilitate the drying of the feed.

[0025] Furthermore, a support column 5 is provided at the center of the inner baffle 44. The support column 5 is fixedly connected to the spiral feeding device 4. The top of the support column 5 is connected to the outer cover 2, and the bottom of the support column 5 is connected to a vibration motor 6. The vibration motor 6 is fixedly connected to the base 1. The vibration motor 6 is of vertical structure. By driving the support column 5 to vibrate up and down through the vibration motor 6, the spiral feeding device 4 is made to vibrate up and down, thereby realizing the feed to slide down along the spiral turntable 41 to the bottom end.

[0026] Furthermore, a rubber pad is provided at the bottom of the base 1, thereby improving the sound insulation performance and the overall stability of the equipment.

[0027] Furthermore, the partition plate 42 is made of ceramic material, and a plurality of air outlet holes are provided on the partition plate 42. The ceramic heat conducting plate not only has the characteristics of a metal heat conducting plate, but also has excellent corrosion resistance and high temperature stability; the hot air can be discharged through the air outlet holes, thereby raising the internal temperature of the outer cover 2 and thus improving the drying effect.

[0028] Working principle of the utility model: When the utility model is in use, the staff adds the feed to be dried through the feed hopper 3, passes hot air through the air inlet pipe 7, and starts the vibration motor 6. The vibration motor 6 drives the support column 5 to vibrate up and down, so that the spiral feeding device 4 vibrates up and down, thereby realizing the feed to slide down along the spiral turntable 41. The hot air contacts with the partition plate 42, so that the partition plate 42 is heated. The feed is dried by contacting with the partition plate 42. The spiral structure of the spiral turntable 41 enables the feed to turn over the upper and lower layers by rolling during the sliding process, and the feed is dried more thoroughly inside and outside. Finally, the feed passes through the spiral discharge chute 9 and is discharged from the discharge pipe 10.

[0029] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the utility model.
