Cooling and dehumidifying mechanism for concentrated feed

Abstract

This utility model discloses a cooling and dehumidifying mechanism for concentrated feed, including material, outer shell, feed inlet, feed outlet, and hot air blower, upper plate and bottom plate, both of which are conical. A feed pipe is installed between the upper plate and the bottom plate, penetrating both plates. A diffusion chamber is located between the upper plate and the bottom plate, and a hole is provided on the side wall of the feed pipe. Hot air generated by the hot air blower contacts the material through the diffusion chamber and the hole. The beneficial effects of this utility model are that the arrangement of the upper plate, bottom plate and feed pipe allows the material to be dispersed as much as possible, ensuring sufficient contact between the dry gas and the material, thus improving the cooling and dehumidifying effect. The air inlet ring allows the airflow to move upward, effectively slowing down the descent speed of the material in the feed pipe and increasing the cooling and dehumidifying time.

Description

Technical Field

[0001] This utility model relates to the field of feed dehumidification technology, and more specifically, to a cooling and dehumidification mechanism for concentrated feed. Background Technology

[0002] Poultry feed is usually concentrated feed. After pelleting, the feed contains heat and moisture due to the extrusion process, so it needs to be dried and cooled. In the existing technology, such as the literature with application number CN202321384218.2, the material is cooled by cooling cylinder and cooling fan. Although cooling and drying can be achieved, it has the following drawbacks: the material tends to accumulate at the bottom of the cooling cylinder, the gaps between the materials are small, and the contact area with the air is small. Utility Model Content

[0003] To address the above deficiencies, this utility model provides a cooling and dehumidification mechanism for concentrated feed, thus solving the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The concentrated feed cooling and dehumidification mechanism includes the material, outer shell, feed inlet, feed outlet, and hot air blower, and also includes... The upper plate and the bottom plate are both conical, and a material pipe is installed between the upper plate and the bottom plate, passing through the upper plate and the bottom plate. The diffusion chamber is located between the upper plate and the bottom plate. The side wall of the material pipe has a hole. The hot air generated by the hot air blower comes into contact with the material through the diffusion chamber and the hole.

[0005] Furthermore, a bearing is installed on the side wall of the upper plate and the bottom plate. The outer ring of the bearing is connected to the outer shell. A transmission rod is installed on the upper surface of the upper plate. The upper end of the transmission rod extends out of the outer shell. A gear ring is installed on the upper end of the transmission rod. A motor is installed on the outer shell. The output end of the motor meshes with the gear ring.

[0006] Furthermore, a material-stopping protrusion is provided at the upper end of the material tube, and the material-stopping protrusion is located near the outer shell.

[0007] Furthermore, an air intake ring is installed at the lower end of the outer casing, which is connected to the diffuser cavity. A delivery pipe is installed between the air intake ring and the hot air blower. An air outlet ring is installed on the upper side wall of the outer casing.

[0008] Furthermore, the intake ring sidewall is equipped with an inclined tube.

[0009] The beneficial effects of this utility model are: by setting up the upper plate, the bottom plate and the material pipe, the material can be dispersed as much as possible, and the dry gas can fully contact the material, thereby improving the cooling and dehumidification effect. By setting up the air intake ring, the airflow can be moved upward, which can effectively slow down the descent speed of the material in the feed pipe and increase the cooling and dehumidification time.

[0011] 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.

[0012] This application provides a cooling and dehumidification mechanism for concentrated feed; please refer to [reference needed]. Figures 1-5 This includes material 1, outer shell 2, inlet 3, outlet 4, and hot air blower 5, and also includes... The upper plate 6 and the bottom plate 7 are both conical. A material pipe 8 is installed between the upper plate 6 and the bottom plate 7, and the material pipe 8 passes through the upper plate 6 and the bottom plate 7. The diffusion chamber 9 is located between the upper plate 6 and the bottom plate 7. The side wall of the material pipe 8 is provided with a hole 10. The hot air generated by the hot air blower 5 comes into contact with the material 1 through the diffusion chamber 9 and the hole 10.

[0013] In practical applications, a negative pressure device can be set up to improve drying efficiency. This device can actively extract the hot air from the exhaust ring 84. During use, material 1 enters the outer shell 2 through the feed inlet 3. Under the action of gravity, material 1 moves from the center of the upper plate 6 to the edge. During this process, material 1 enters the feed pipe 8. The diameter of the feed pipe 8 is larger than the diameter of one material 1 particle but smaller than the diameter of two material 1 particles. This setting can ensure that material 1 enters the feed pipe 8 while avoiding horizontal overlap of material 1, thus increasing the contact area with hot air. At the same time, the upper plate 6 and the bottom plate 7 are controlled to rotate synchronously, which is conducive to the material 1 entering the material pipe 8. By setting the negative pressure device, the hot airflow can move upward, which can slow down the falling speed of the material 1 and extend the dehumidification and cooling time.

[0014] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Bearing 71 is installed on the side wall of the upper plate 6 and the bottom plate 7. The outer ring of bearing 71 is connected to the outer shell 2. A transmission rod 72 is installed on the upper surface of the upper plate 6. The upper end of the transmission rod 72 extends out of the outer shell 2. A gear ring 73 is installed on the upper end of the transmission rod 72. A motor 74 is installed on the outer shell 2. The output end of the motor 74 meshes with the gear ring 73.

[0015] In practical applications, the bearing 71 allows the upper plate 6 and the bottom plate 7 to be rotatable, and the output of the motor 74 can directly drive the gear ring 73, the transmission rod 72, the upper plate 6, and the bottom plate 7 to reciprocate.

[0016] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The upper end of the feed tube 8 is provided with a material-stopping protrusion 81, which is located near the outer shell 2.

[0017] In practical applications, by setting the material blocking protrusion 81, the material 1 can be prevented from directly passing over the top of the material pipe 8, so that the material 1 can enter the material pipe 8 as much as possible.

[0018] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An air intake ring 82 is installed at the lower end of the outer casing 2. The air intake ring 82 is connected to the diffuser 9. A delivery pipe 83 is installed between the air intake ring 82 and the hot air blower 5. An air outlet ring 84 is installed on the upper side wall of the outer casing 2.

[0019] In practical applications, hot air enters the outlet 4 and the diffuser 9 through the inlet ring 82; the design of the inclined tube 821 allows the hot air to be blown upwards.
