[0002] Colistin sulfate soluble powder for poultry and livestock is widely used in livestock and poultry farming, showing significant effects in preventing and treating intestinal diseases and promoting growth and development. To comply with veterinary drug production standards, ensure consistent and stable product quality, and meet market demand for efficient and high-quality products, it is essential to design an integrated and intelligent processing device. This device encompasses core processes such as crushing, mixing, granulation, drying, and packaging to achieve continuous and automated production. After wet granulation, the wet granules require rapid drying and precise moisture control.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A processing device for soluble colistin sulfate powder for poultry and livestock includes a vertically arranged drying tank. A fixed plate is horizontally fixed inside the drying tank, and the fixed plate divides the inner cavity of the drying tank into a drying area and a discharge area from top to bottom. The fixed plate is equipped with a control structure for switching the drying area and the discharge area on and off.

[0011] The drying area is provided with a guide tube that slides vertically, and there is a return flow interval between the lower end of the guide tube and the fixed plate. The control structure is provided with an air distribution structure that blows air into the guide tube.

[0012] As an optimized solution, a baffle is fixedly installed above the guide tube in the drying area, and an air passage is provided between the outer edge of the baffle and the inner wall of the drying tank.

[0013] As an optimized solution, the baffle is arranged in an arc-shaped cover, with the open end of the baffle facing downwards.

[0015] As an optimized solution, a support rod is horizontally fixed to the inner wall of the drying tank, and a support sleeve is fixed between the opposite ends of the two support rods. The guide cylinder is threaded into the support sleeve.

[0016] As an optimized solution, the control structure includes a valve disc rotatably mounted on the fixed disk, the fixed disk having a plurality of fan-shaped material discharge holes around its center, and the valve disc having a plurality of fan-shaped closing plates that match the fan-shaped material discharge holes.

[0018] As an optimized solution, a discharge cylinder that communicates with the discharge area is obliquely fixed to the outer wall of the drying tank, and the inner bottom surface of the drying tank is obliquely arranged, with the discharge cylinder close to the lower side of the bottom surface.

[0019] As an optimized solution, a drying air inlet cylinder that connects to the discharge area is fixedly connected to the outer wall of the drying tank.

[0020] As an optimized solution, a locking sleeve is threaded onto the guide tube, and the lower surface of the locking sleeve abuts against the upper surface of the support sleeve.

[0021] As an optimized solution, the inner holes of the support sleeve and the locking sleeve are respectively provided with internal threads, and the outer wall of the guide tube is provided with an external thread section that matches the internal threads.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] High-pressure drying air is introduced through the dry air inlet cylinder, and wet particles are introduced through the feed cylinder. The wet particles pass through the reflux interval and accumulate above the fixed plate. Due to the introduction of drying air, the drying air is sprayed into the guide cylinder through the blow holes. The material rises with the airflow until it hits the baffle and falls in all directions. Then it passes through the reflux interval and accumulates above the fixed plate, realizing the circulation of the contact spray drying airflow. This achieves the circulation drying of wet particles, increases the mobility of wet particles, and increases the drying uniformity with the drying airflow.

[0030] By rotating the guide tube, the distance between its lower end and the valve disc can be adjusted, the inlet height of the reflux interval can be adjusted, and the amount of wet particles entering the nozzle can be adjusted. This allows for the adjustment of the amount of wet particles participating in drying per unit time, thereby improving drying efficiency.

[0031] After the wet granules are dried, the drive motor rotates the valve disc, and the area between the two fan-shaped closed plates is aligned with the fan-shaped discharge hole, so that the dried granules fall into the discharge area. The dried material is then discharged by opening the discharge cylinder, which is convenient and quick. Attached Figure Description

[0041] The baffle 10 is set in an arc shape, with the open end of the baffle 10 facing downwards.

[0042] A feed cylinder 13 is fixedly attached to the outer wall of the drying tank 1 at an angle downwards, and the outlet end of the feed cylinder 13 is connected to the drying area 3.

[0043] A support rod 6 is horizontally fixed to the inner wall of the drying tank 1, and a support sleeve 7 is fixed between the opposite ends of the two support rods 6. The guide tube 5 is threaded into the support sleeve 7.

[0044] The control structure includes a valve disc 19 rotatably mounted on a fixed disk 2. The fixed disk 2 has several fan-shaped material discharge holes 18 arranged around its center. The valve disc 19 has several fan-shaped closing plates 20 that match the fan-shaped material discharge holes 18.

[0045] The air distribution structure includes several spray holes 17 evenly distributed at the center of the valve disc 19, and the spray holes 17 connect the drying area 3 and the discharge area 4.

[0046] A discharge cylinder 14, which connects to the discharge area 4, is obliquely fixed to the outer wall of the drying tank 1. The inner bottom surface of the drying tank 1 is obliquely arranged, and the discharge cylinder 14 is close to the lower side of the bottom surface.

[0047] A drying air inlet 15, which connects to the discharge area 4, is fixedly attached to the outer wall of the drying tank 1. The drying air inlet 15 is connected to the drying airflow through an air purification device and high-pressure air delivery is achieved through a centrifugal fan.

[0048] A locking sleeve 8 is threaded onto the guide tube 5, and the lower surface of the locking sleeve 8 abuts against the upper surface of the support sleeve 7.

[0049] The inner holes of the support sleeve 7 and the locking sleeve 8 are respectively provided with internal threads, and the outer wall of the guide tube 5 is provided with an external thread section that matches the internal threads.

[0050] The upper surface of the baffle 10 is fixed to the inner top surface of the drying tank 1 by parallel hanging rods 11.

[0051] An exhaust pipe 12 is fixedly connected to the top of the drying tank 1, and the exhaust pipe 12 is connected to a bag filter dust collector.

The wet particles pass through the return interval 16 and accumulate above the fixed plate 2. Due to the introduction of drying air, the drying air is sprayed into the guide cylinder 5 through the blow hole 17. The material will rise with the airflow until it hits the baffle 10 and then falls in all directions. Then it passes through the return interval 16 and gathers above the fixed plate 2, realizing the circulating contact spray drying airflow, realizing the circulating drying of wet particles, increasing the mobility of wet particles, and increasing the drying uniformity with the drying airflow.

[0060] By rotating the guide tube 5, the distance between its lower end and the valve disc 19 can be adjusted, and the inlet height of the return interval 16 can be adjusted, thereby adjusting the amount of wet particles entering above the spray hole 17. This allows for the adjustment of the amount of wet particles participating in drying per unit time, thus improving drying efficiency.

[0061] After the wet granules are dried, the drive motor 21 drives the valve disc 19 to rotate. The area between the two fan-shaped closed plates 20 is aligned with the fan-shaped discharge hole 18, so that the dried granules fall into the discharge area 4. The dried material is discharged by opening the discharge cylinder 14, which is convenient and quick.
