Description

Technical Field

[0001] This utility model relates to a drying equipment for the production of florfenicol powder, belonging to the field of florfenicol powder drying technology. Background Technology

[0002] Florfenicol powder is a veterinary antibiotic primarily used to treat bacterial infections in poultry, pigs, and other animals. Its chemical name is florfenicol, belonging to the amide alcohol class of antibiotics. Its mechanism of action is similar to chloramphenicol, inhibiting bacterial growth by interfering with bacterial protein synthesis. The production process of florfenicol powder includes a drying step, currently often using a drum dryer. Florfenicol powder with a certain moisture content is added to the drum, and a fan at one end of the drum blows heat into the drum. Combined with lifting plates on the drum wall, the florfenicol powder is lifted and dried by the hot air, achieving the desired drying effect.

[0003] However, the above drying process has the following inconveniences: First, after the powdered florfenicol is added to the dryer, it cannot be guaranteed that the powder will be evenly dispersed and will not be able to fully contact the hot air, which greatly reduces the drying effect; Second, the powder is not easy to be automatically discharged after drying.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This utility model addresses the shortcomings of the prior art by providing a drying device for the production of florfenicol powder, which allows the powder to fall in a fully dispersed manner during feeding, greatly enhancing the drying effect, and automatically discharging the dried material.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A drying device for producing florfenicol powder includes a tank, in which a first conical plate, a second conical plate, and a third conical plate are arranged sequentially from top to bottom, all three being conical in shape with a smaller upper end and a larger lower end.

[0008] Both the first and second conical plates have circular clearance holes in the middle, and the diameter of the clearance hole in the first conical plate is larger than that in the second conical plate. The top of the third conical plate is sealed.

[0009] The outer diameters of the first, second, and third conical plates increase sequentially.

[0010] The top of the tank is equipped with a hopper, and the lower end of the hopper is directly opposite the first conical plate.

[0011] Furthermore, a connecting cylinder is coaxially fixed to the lower surface of both the first and second conical plates. The connecting cylinder on the lower side of the first conical plate is connected to the upper surface of the second conical plate through multiple connecting pieces, and the connecting cylinder on the lower side of the second conical plate is connected to the upper surface of the third conical plate through multiple connecting pieces.

[0012] Furthermore, a connecting flange is provided above the first conical plate. The connecting flange is installed on the top wall of the tank. The hopper is installed above the connecting flange. The connecting flange is connected to the upper surface of the first conical plate through a connecting piece. The inner diameter of the connecting flange is larger than the clearance hole of the first conical plate.

[0013] Furthermore, the lower surface of the flange is provided with an external toothed slewing bearing, which meshes with a drive gear, and the drive gear is driven by a drive motor.

[0014] Furthermore, the flange has multiple flow equalization plates arranged side by side inside, and the flow equalization plates are arranged at intervals.

[0015] Furthermore, a spray pipe is fitted on the outer side of the lower end of the tank, and multiple nozzles are evenly arranged on the inner side of the spray pipe, with the nozzles extending into the interior of the tank.

[0016] Furthermore, a rotating shaft is vertically fixed to the lower surface of the third conical plate, the rotating shaft extends downward to the bottom of the tank, a lever is installed at the lower end of the rotating shaft, and a discharge pipe is also provided at the bottom of the tank.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0018] The powder fed into the hopper slides outwards along the wall of the first conical plate, the middle layer slides outwards along the wall of the second conical plate, and the inner layer slides outwards along the wall of the third conical plate. As the outer diameters of the first, second, and third conical plates increase sequentially, the powder sliding down from the three conical plates can flow down to the bottom of the tank in layers, allowing the powder to fall in a fully dispersed manner, which greatly enhances the drying effect.

[0019] After the material falls evenly, the nozzle sprays high-temperature gas to fully dry the material. The dried material is then automatically discharged by the action of the paddle.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] like Figure 1 As shown, this utility model provides a drying equipment for the production of florfenicol powder, including a tank 1. The tank 1 is provided with a first conical plate 2, a second conical plate 3 and a third conical plate 4 arranged sequentially from top to bottom. All three are conical in shape with a smaller upper end and a larger lower end.

[0028] like Figure 2 The first conical plate 2 and the second conical plate 3 are both provided with circular clearance holes in the middle, and the diameter of the clearance hole of the first conical plate 2 is larger than the diameter of the clearance hole of the second conical plate 3. The top of the third conical plate 4 is sealed.

[0029] The outer diameters of the first conical plate 2, the second conical plate 3, and the third conical plate 4 increase sequentially.

[0030] The top of the tank body 1 is provided with a hopper 12, and the lower end of the hopper 12 is directly opposite the first conical plate 2.

[0031] A connecting cylinder 5 is coaxially fixed to the lower surface of both the first conical plate 2 and the second conical plate 3. The connecting cylinder 5 on the lower side of the first conical plate 2 is connected to the upper surface of the second conical plate 3 through multiple connecting pieces 6, and the connecting cylinder 5 on the lower side of the second conical plate 3 is connected to the upper surface of the third conical plate 4 through multiple connecting pieces 6. Thus, the first conical plate 2, the second conical plate 3, and the third conical plate 4 are coaxially and fixedly connected vertically.

[0032] A connecting flange 7 is provided above the first conical plate 2. The connecting flange 7 is installed on the top wall of the tank body 1. The hopper 12 is installed above the connecting flange 7. The connecting flange 7 is connected to the upper surface of the first conical plate 2 through a connecting piece 6. The inner diameter of the connecting flange 7 is larger than the clearance hole of the first conical plate 2.

[0033] The lower surface of the flange 7 is provided with an external tooth slewing bearing 8, which meshes with a drive gear 9 for transmission. The drive gear 9 is driven by a drive motor 10.

[0034] Furthermore, the flange 7 has multiple flow equalization plates 11 arranged side by side inside, with the flow equalization plates 11 spaced apart. The powder fed from the hopper 12 falls evenly under the action of the flow equalization plates 11.

[0035] Florfenicol powder is added from hopper 12. Since the clearance hole of the first conical plate 2 is smaller than the inner diameter of the connecting flange 7, a portion of the powder in the middle leaks out of the clearance hole of the first conical plate 2, while the powder at the edge slides outward along the wall of the first conical plate 2. Similarly, a portion of the powder leaking out of the clearance hole of the first conical plate 2 leaks out of the clearance hole of the second conical plate 3, while the powder at the edge slides outward along the wall of the second conical plate 3. Finally, the powder leaking out of the clearance hole of the second conical plate 3 slides outward along the wall of the third conical plate 4. In this way, the powder fed into the hopper 12 slides outwards along the wall of the first conical plate 2, the middle layer slides outwards along the wall of the second conical plate 3, and the inner layer slides outwards along the wall of the third conical plate 4. Because the outer diameters of the first, second, and third conical plates 2, 3, and 4 increase sequentially, the powder sliding down from the three plates can flow in layers towards the bottom of the tank 1, allowing the powder to fall in a fully dispersed manner, greatly enhancing the drying effect. Furthermore, the upper ends of the first, second, and third conical plates 2, 3, and 4 rotate under the drive of the drive motor 10, causing the material to rotate and further accelerating the drying process.

[0036] A nozzle 14 is fitted onto the outer side of the lower end of the tank body 1. Multiple nozzles 15 are evenly arranged on the inner side of the nozzle 14, and the nozzles 15 extend into the interior of the tank body 1. Figure 3 .

[0037] A rotating shaft 13 is vertically fixed to the lower surface of the third conical plate 4. The rotating shaft 13 extends downward to the bottom of the tank body 1. A lever 16 is installed at the lower end of the rotating shaft 13. Figure 4 A discharge pipe 17 is also provided at the bottom of the tank body 1. The material is automatically discharged when the paddle 16 is turned.

[0038] After the material falls evenly, the nozzle 15 sprays high-temperature gas to fully dry the material. The dried material is then automatically discharged by the paddle 16.
