Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a particle drying device. Background Art

[0002] In industries such as plastic processing and food processing, raw materials, semi-finished products or products generally exist in the form of particles, such as plastic masterbatch in plastic processing, beans and feed in the food processing industry. These particles themselves have a certain amount of water content, or will absorb a certain amount of water after being placed for a period of time. The presence of water will affect the subsequent product processing or the quality of the final product. Therefore, drying the above particles is often a necessary operation in the processing process.

[0003] In the prior art, the above-mentioned granules are generally stored in a box, and the granules are dried by external heating elements or direct hot air blowing. However, since the granular materials are arranged closely, when drying large quantities of materials, the granular materials are closely arranged due to pressure, which easily causes poor air circulation inside the drying device, affecting the air circulation inside the materials during the material drying process, reducing the drying efficiency and drying effect. Even if there is a stirring device to stir the granules, the granules will still accumulate in the lower part of the box under the action of gravity, and the fluidity of the granules in the box is poor, resulting in a slow drying speed. Utility Model Content

[0004] Based on this, it is necessary to provide a particle drying device that improves the particle drying efficiency by improving the fluidity of the particle, in order to address the technical problem of low drying efficiency of the particle in the box.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a particle drying device, including a shell and a hot air blower, a lower opening is provided at the bottom of the shell, an upper opening is provided at the top of the shell, an output end of the hot air blower is communicated with the bottom of the shell, a breathable drying cylinder is rotatably installed in the shell, a material port is provided at one end of the breathable drying cylinder, a first valve is installed at the material port, a first rotating shaft is rotatably installed in the breathable drying cylinder, a first bevel gear is fixed on the first rotating shaft, a protective shell is rotatably installed on the first rotating shaft, the first bevel gear is located in the protective shell, a driving shaft is fixedly installed at one end of the protective shell, and a second rotating shaft is rotatably installed at the other end, a second bevel gear is installed on the second rotating shaft, the second bevel gear is meshed with the first bevel gear, the driving shaft is rotatably connected with the shell, a first driving motor and a second driving motor are fixedly installed on the shell, the first driving motor is transmission-connected to the driving shaft, the second driving motor is transmission-connected to the second rotating shaft, a plurality of rotating disks are fixed in the axial direction of the first rotating shaft, and two symmetrically arranged and connected conical ring plates are fixed on the inner wall of the breathable drying cylinder and between any two adjacent rotating disks.

[0006] Preferably, an air supply annular pipe is fixed to the bottom of the housing. A plurality of air inlets communicating with the air supply annular pipe are provided in the bottom of the housing. The output end of the hot air blower is communicated with the air supply annular pipe through a hot air pipe.

[0007] Preferably, the air-permeable drying cylinder, the rotating disk, and the conical ring plate are all made of wire mesh.

[0008] Preferably, a second valve is installed at the lower layer opening.

[0009] Preferably, the inner diameter of the conical ring plate is smaller than the outer diameter of the rotating disk.

[0010] Preferably, the first driving motor is installed on the outer wall of the housing through a first mounting seat, and the second driving motor is installed on the outer wall of the housing through a second mounting seat.

[0011] Preferably, the housing, the second rotating shaft, and the driving shaft are coaxially arranged.

[0013] Beneficial effects of the technical solution: The rotating disk is driven to rotate by the first rotating shaft, and the particulate matter on the rotating disk is thrown off.

Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

The breathable drying cylinder 4 is a capsule-shaped structure, and the shell 1 is a hollow flat disc-shaped structure, which is convenient for the breathable drying cylinder 4 to rotate in the shell 1. The breathable drying cylinder 4 is made of a porous breathable material, and a material port 5 is provided at one end of the breathable drying cylinder 4. A first valve 6 is installed at the material port 5, and a second valve 6 is installed at the material port 5. A valve 6 is a manual butterfly valve. A first rotating shaft 7 is rotatably installed in the air-permeable drying cylinder 4. The first rotating shaft 7 is connected to the air-permeable drying cylinder 4 of the housing 1 through a bearing. A first bevel gear 8 is fixed on the first rotating shaft 7. A protective shell 9 is rotatably installed on the first rotating shaft 7 through a bearing. The first bevel gear 8 is located in the protective shell 9. A driving shaft 10 is fixedly installed at one end of the protective shell 9, and a second rotating shaft 11 is rotatably installed at the other end through a bearing. The driving shaft 10 is fixedly connected to the air-permeable drying cylinder 4. A second bevel gear 12 is installed on the second rotating shaft 11. The second bevel gear The wheel 12 is meshed with the first bevel gear 8, the drive shaft 10 is rotatably connected to the housing 1 through a bearing, the housing 1, the second rotating shaft 11, and the drive shaft 10 are coaxially arranged, and the housing 1 is fixedly mounted with a first drive motor 13 and a second drive motor 14, the first drive motor 13 is transmission-connected to the drive shaft 10, the first drive motor 13 is connected to the drive shaft 10 through a coupling, the second drive motor 14 is transmission-connected to the second rotating shaft 11, the second drive motor 14 is connected to the second rotating shaft 11 through a coupling, and the first rotating shaft 7 is axially fixed. There are multiple rotating disks 15, and two symmetrically arranged and connected conical ring plates 16 are fixed on the inner wall of the breathable drying cylinder 4 and between any two adjacent rotating disks 15. The conical surface of the inner wall of the conical ring plate 16 can be used to conveniently guide the particles to the rotating disk 15. The conical ring plates 16 are symmetrically arranged in two so that after the breathable drying cylinder 4 rotates 180 degrees, the two conical ring plates 16 can work alternately to guide the particles; the rotating disk 15 and the conical ring plate 16 are also made of porous breathable materials, which is convenient for air circulation and full contact with the particles.

[0022] In this embodiment, the driving shaft 10 is driven to rotate by the first driving motor 13, and the driving shaft 10 drives the protective shell 9 and the breathable drying cylinder 4 to rotate, so that the material port 5 is rotated to a vertical upward angle, and the material port 5 is located directly below the upper opening 24. At this time, the first valve 6 can be opened, and the particles to be dried are added to the material port 5 through the upper opening 24; then the first valve 6 is closed, and the hot air blower 2 and the second driving motor 14 are started, and the hot air blower 2 passes hot air into the shell 1, and the hot air enters the breathable drying cylinder 4 and contacts the particles to dry the particles, and finally the hot air is discharged from the upper opening 24;

[0023] The second drive motor 14 drives the second rotating shaft 11 to rotate. The second rotating shaft 11 drives the first bevel gear 8 and the first rotating shaft 7 to rotate through the second bevel gear 12. The first rotating shaft 7 drives the rotating disk 15 to rotate, and the particulate matter on the rotating disk 15 is thrown off. The particulate matter is thrown onto the closest conical ring plate 16 below, and then is guided by the conical ring plate 16 to the closest rotating disk 15 below, so that the particulate matter descends layer by layer until it falls to the bottom of the air-permeable drying cylinder 4, thereby improving the fluidity of the particulate matter, increasing the falling time of the particulate matter in the air, and improving the contact effect between the particulate matter and the hot air;

[0024] After a period of time, the particulate matter basically falls to the bottom of the air-permeable drying cylinder 4. At this time, the first drive motor 13 works. The first drive motor 13 drives the drive shaft 10 to rotate 180 degrees, and then drives the air-permeable drying cylinder 4 to rotate 180 degrees, so that the particulate matter at the bottom of the air-permeable drying cylinder 4 rotates to the top and undergoes the falling and drying process from top to bottom again; repeating like this can prevent the particulate matter from accumulating at the bottom of the air-permeable drying cylinder 4, improve the fluidity of the particulate matter, improve the contact effect between the particulate matter and the hot air, and improve the drying efficiency;

[0025] After the particulate matter is dried, when the material inlet 5 is at the upper opening 24, the first valve 6 is opened, and then the first drive motor 13 is controlled to drive the drive shaft 10 and the air-permeable drying cylinder 4 to rotate, so that the material inlet 5 rotates to the lower opening 3, and the material in the air-permeable drying cylinder 4 can be discharged through the material inlet 5 and the lower opening 3.

[0026] In a preferred embodiment, to enable the hot air blower 2 to uniformly deliver hot air into the housing 1, please refer to Figure 1 and Figure 2 , a air supply ring pipe 17 is fixed at the bottom of the housing 1, and a plurality of air inlets 18 communicating with the air supply ring pipe 17 are opened at the bottom of the housing 1. The output end of the hot air blower 2 is communicated with the air supply ring pipe 17 through a hot air pipe 19. By providing a plurality of air inlets 18, the hot air blower 2 can uniformly deliver hot air into the housing 1, so that the hot air can uniformly contact the particulate matter and avoid the problem of poor air fluidity in a local area of the air-permeable drying cylinder 4.

[0027] In a preferred embodiment, to facilitate the circulation of air in the air-permeable drying cylinder 4, please refer to Figure 4 and Figure 5 , the air-permeable drying cylinder 4, the rotating disk 15, and the conical ring plate 16 are all made of metal wire mesh. The material of the metal wire mesh can specifically be steel wire mesh, which can facilitate air circulation and can block the particulate matter; the mesh holes of the mesh need to be smaller than the particle size of the particulate matter to prevent the particulate matter from falling through the mesh holes.

[0028] In a preferred embodiment, to prevent the hot air from being discharged from the lower opening 3, please refer to Figure 1 and Figure 2, a second valve 20 is installed at the lower opening 3, and the second valve 20 is a manual butterfly valve. When drying particulate matter, the second valve 20 is closed so that the hot air in the housing 1 flows from bottom to top. After the particulate matter is dried, the first valve 6 is opened first, and then the second valve 20 is opened to facilitate the discharge of the material.

[0029] In a preferred embodiment, to facilitate the conical ring plate 16 to fully guide the particulate matter onto the rotating disk 15, please refer to Figure 1 and Figure 2 , the inner diameter of the conical ring plate 16 is set to be smaller than the outer diameter of the rotating disk 15. In this way, the particulate matter on the conical ring plate 16 will not fall vertically through the gap between the conical ring plate 16 and the rotating disk 15 under the action of gravity, thereby increasing the falling time of the particulate matter and improving the contact efficiency between the particulate matter and the hot air.

[0030] In a preferred embodiment, to facilitate the installation of the first driving motor 13 and the second driving motor 14, please refer to Figure 1 and Figure 3 , the first driving motor 13 is installed on the outer wall of the housing 1 through the first mounting seat 21, and the second driving motor 14 is installed on the outer wall of the housing 1 through the second mounting seat 22.
