Description

Technical Field

[0001] The present application relates to the technical field of drying, and in particular to a composite particle drying device. Background Art

[0002] The development of modern high technology is inseparable from composite materials. Composite materials play a very important role in the development of modern science and technology. The research depth and application breadth of composite materials and the speed and scale of their production development have become one of the important indicators to measure the advanced level of science and technology of a country. In the prior art, composite materials are pelletized by extrusion and water cooling during manufacturing. The pelletized composite material particles have a lot of moisture and cannot be used for direct processing. The wet composite material particles need to be dried. The existing composite particle drying device mainly uses hot air to make the composite particles realize fluidized state in the tank body for rapid drying.

[0003] However, the existing composite particle drying device has the following defects: the hot air flows from bottom to top in the tank body, and the fluidized state of the composite particles is not good due to the obstruction of the fluidized bed in the tank body, the drying effect and drying efficiency are reduced, and the dried composite particles are easy to flow out of the tank body with the hot air due to the reduction of gravity, and are not easy to recover, which is easy to cause material loss.

[0004] Therefore, how to improve the existing composite particle drying device to overcome the above-mentioned deficiencies is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] One purpose of the present application is to provide a composite particle drying device with good fluidization state, high drying effect and drying efficiency, and avoidance of material loss.

[0006] In order to achieve the above objectives, the technical solution adopted in the present application is: a composite particle drying device, comprising a cylinder, a blowing assembly, a fluidized bed, a guide assembly and a leak-proof assembly; a feed port and an air outlet are provided at the upper end of the cylinder, a discharge port and an air inlet are provided at the lower end of the cylinder, and the blowing assembly is connected to the air inlet; there are multiple fluidized beds, and the multiple fluidized beds are arranged in the cylinder at equal intervals along the up and down directions, thereby dividing the cylinder into multiple fluidized chambers; the guide assembly is arranged on the upper surface of each fluidized bed and is used to redirect part of the hot air from bottom to top to the fluidized bed; the leak-proof assembly is arranged at the air outlet of the cylinder and is used to prevent the composite particles from leaking out through the air outlet.

[0007] As a preferred embodiment, the fluidized bed includes two bed bodies, two driving rods and a driving member. The two bed bodies are symmetrically and rotatably arranged in the cylinder to control the opening and closing of each fluidized chamber. One end of each driving rod is connected to each bed body and the other end extends to the outside of the cylinder. The driving member is arranged on the cylinder and is used to drive the bed body to rotate with the driving rod. The advantage is that the opening and closing function of the fluidized bed is realized through this structure, so that the composite particles enter each fluidized chamber from top to bottom in turn for step-by-step drying.

[0008] Preferably, the fluidized bed further comprises a mounting bearing, wherein the mounting bearing is arranged on the two driving rods, and the two driving rods are rotationally connected to the bearings; the leakage prevention assembly comprises a shaft rod, a plurality of baffles and a plurality of driving blades, wherein the shaft rod is rotationally connected to the mounting bearing, and the upper end of the shaft rod extends to the air outlet, a plurality of baffles are arranged on the shaft rod at equal intervals along the circumference of the cylinder and are located between the fluidized bed and the air outlet, a plurality of driving blades are arranged at equal intervals along the circumference of the cylinder at the upper end of the shaft rod and rotate in coordination with the outflow of hot air in the air outlet, thereby driving the baffles to rotate with the shaft rod. Its advantages are: the shaft is installed by the mounting bearing, so that the baffle and the driving blade can be rotatably installed; when the composite particles on the fluidized bed fluidize to the baffle, the rotating baffle breaks the composite particles to the surroundings, which not only prevents the composite particles from continuing to move upward and leak out through the air outlet, but also improves the fluidization effect of the composite particles after being broken up; when some composite particles flow to the driving blade with the hot air, the driving blade drives the baffle to rotate with the shaft to further prevent the composite particles from leaking out, which not only has a good anti-leakage effect, but also has an ingenious structure and reduces the use of the driving structure.

[0009] As a preferred embodiment, the lower end of the shaft extends downward into each of the fluidizing chambers, and the baffle is provided at a position on the shaft corresponding to each of the fluidizing chambers. The advantage is that the baffle pushes the composite particles in each of the fluidizing chambers to disperse, thereby improving the fluidization effect of the composite particles in each of the fluidizing chambers and improving the drying efficiency.

[0010] As a preferred embodiment, the cylinder expands outward at the position corresponding to the baffle to form a slow flow cavity, and the inner wall at the lower end of the slow flow cavity is formed as a guide slope for guiding the composite particles downward. The advantage is that the slow flow cavity can reduce the flow rate of the hot air and improve the effect of the baffle on the dispersion of the composite particles. The combination of the two can better prevent the composite particles from continuing to move upward and leaking through the air outlet.

[0011] As a preferred embodiment, the anti-leakage assembly further comprises a stirring plate, the lower end of the shaft extends downward to the discharge port, and the stirring plate is arranged at the lower end of the shaft and is used to stir the composite particles. The advantage is that the stirring of the stirring plate can avoid the material jamming during discharge.

[0012] As a preferred embodiment, the flow guide assembly includes a wind shield and a connecting rod, wherein the wind shield is arranged above the fluidized bed at equal intervals along the circumference of the cylinder, and the two ends of the connecting rod are respectively connected to the wind shield and the fluidized bed, so that the wind blown out through the blowing holes on the fluidized bed is blocked by the wind shield to flow back and blow up the composite particles between the blowing holes. The advantage is that the hot air is redirected to the fluidized bed through the wind shield, and the composite particles between the blowing holes are blown to a fluidized state, and the fluidization effect is good.

[0013] As a preferred embodiment, the wind shield is a conical shield structure, which has the advantages that the lower end of the wind shield with such structure can redirect the gas to the fluidized bed and blow up the composite particles thereon, while the upper end can prevent the composite particles from accumulating, so that the composite particles slide down to the fluidized bed and are re-fluidized.

[0014] Compared with the prior art, the beneficial effects of the present application are as follows: by setting a plurality of the fluidized beds, the cylinder is divided into a plurality of the fluidized chambers, so that the composite particles are sequentially passed through each of the fluidized chambers from top to bottom for patching and drying, which not only allows the hot air to be used multiple times through each of the fluidized chambers, thereby improving the drying effect and drying efficiency, but also the composite particles in the fluidized chamber at the upper end of the cylinder are always in a wet state, with a greater gravity, thereby reducing the composite particles from flowing into the air outlet with the hot air, thereby avoiding material loss; by setting the guide assembly on each of the fluidized beds, part of the hot air is redirected to the fluidized bed, thereby avoiding the obstruction of the fluidized bed and causing the fluidization state to decrease; by setting the anti-leakage mechanism at the air outlet, the composite particles are further prevented from leaking out through the air outlet, thereby further avoiding material loss. It can be seen from this that the composite particle drying device has a good fluidized state, high drying effect and drying efficiency, and avoids material loss. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Reference Figure 1-5One embodiment of the present application provides a composite particle drying device, comprising a cylinder 1, a blowing assembly 2, a fluidized bed 3, a guide assembly 4 and a leak-proof assembly 5; a feed port 11 and an air outlet 12 are provided at the upper end of the cylinder 1, a discharge port 13 and an air inlet 14 are provided at the lower end of the cylinder 1, and the blowing assembly 2 is connected to the air inlet 14; there are multiple fluidized beds 3, and the multiple fluidized beds 3 are arranged in the cylinder 1 at equal intervals along the up and down directions, so that the cylinder 1 is divided into multiple fluidized chambers 15; the guide assembly 4 is arranged on the upper surface of each fluidized bed 3 and is used to redirect part of the hot air from the bottom to the top to the fluidized bed 3; the leak-proof assembly 5 is arranged at the air outlet 12 of the cylinder 1 and is used to prevent the composite particles from leaking out through the air outlet 12. By setting up multiple fluidized beds 3, the cylinder 1 is divided into multiple fluidized chambers 15, so that the composite particles are repaired and dried in each fluidized chamber 15 from top to bottom. This not only allows the hot air to be used multiple times through each fluidized chamber 15, improving the drying effect and drying efficiency, but also the composite particles in the fluidized chamber 15 at the upper end of the cylinder 1 are always in a wet state, with a larger gravity, reducing the composite particles from flowing into the air outlet 12 with the hot air, and avoiding material loss; by setting a guide component 4 on each fluidized bed 3, part of the hot air is redirected to the fluidized bed 3, avoiding the obstruction of the fluidized bed 3 and causing the fluidization state to decrease; by setting a leak-proof mechanism at the air outlet 12, the composite particles are further prevented from leaking out through the air outlet 12, and material loss is further avoided. It can be seen from this that the composite particle drying device has a good fluidized state, high drying effect and drying efficiency, and avoids material loss.

[0026] It should be noted that the blowing assembly 2 is a blower capable of blowing hot air, and both the blowing assembly 2 and the installation method thereof are prior art, and will not be described in detail here.

[0027] Reference Figure 2-5 In some embodiments of the present application, the fluidized bed 3 includes two bed bodies 31, two driving rods 32 and a driving member 33. The two bed bodies 31 are symmetrically and rotatably arranged in the cylinder 1 to control the opening and closing of each fluidizing chamber 15. One end of each driving rod 32 is connected to each bed body 31 and the other end extends to the outside of the cylinder 1. The driving member 33 is arranged on the cylinder 1 and is used to drive the bed body 31 to rotate with the driving rod 32. The opening and closing function of the fluidized bed 3 is realized by this structure, so that the composite particles enter each fluidizing chamber 15 from top to bottom in turn for step-by-step drying.

[0028] It should be noted that the application does not limit the specific structure of the driving member 33. The two driving rods 32 can be driven to rotate by two motors respectively, or the two driving rods 32 can be driven to rotate simultaneously by one motor in conjunction with a gear structure. The above driving methods are all existing technologies and will not be described in detail here.

[0029] Reference Figure 2-5In some embodiments of the present application, the fluidized bed 3 also includes a mounting bearing 34, which is arranged on two driving rods 32, and the two driving rods 32 are rotatably connected to the bearings; the leakage prevention component 5 includes a shaft 51, a plurality of baffles 52 and a plurality of driving blades 53, the shaft 51 is rotatably connected to the mounting bearing 34, and the upper end of the shaft 51 extends to the air outlet 12, a plurality of baffles 52 are arranged on the shaft 51 at equal intervals along the circumference of the cylinder 1 and are located between the fluidized bed 3 and the air outlet 12, a plurality of driving blades 53 are arranged at equal intervals along the circumference of the cylinder 1 at the upper end of the shaft 51 and rotate in conjunction with the outflow of hot air in the air outlet 12, thereby driving the baffles 52 to rotate with the shaft 51. By installing the bearing 34 and the shaft 51, the baffle 52 and the driving blade 53 are rotatably installed. When the composite particles on the fluidized bed 3 are fluidized to the baffle 52, the rotating baffle 52 breaks the composite particles to the surroundings, which not only prevents the composite particles from continuing to move upward and leaking out through the air outlet 12, but also improves the fluidization effect of the composite particles after being broken up. When some composite particles flow to the driving blade 53 with the hot air, the driving blade 53 drives the baffle 52 to rotate with the shaft 51, thereby further preventing the composite particles from leaking out. Not only is the anti-leakage effect good, but the structure is also ingenious, and the use of the driving structure is reduced.

[0030] Reference Figure 2 as well as Figure 4 In some embodiments of the present application, the lower end of the shaft 51 extends downward into each fluidizing cavity 15, and a baffle 52 is provided on the shaft 51 at a position corresponding to each fluidizing cavity 15. The baffle 52 disperses the composite particles in each fluidizing cavity 15, thereby improving the fluidization effect of the composite particles in each fluidizing cavity 15 and improving the drying efficiency.

[0031] Reference Figure 2 as well as Figure 4 In some embodiments of the present application, the cylinder 1 expands outward at the position corresponding to the baffle 52 to form a slow flow chamber 16, and the inner wall of the lower end of the slow flow chamber 16 is formed as a guide slope 17 for guiding the composite particles downward. The slow flow chamber 16 not only reduces the flow rate of the hot air, but also improves the effect of the baffle 52 on the dispersion of the composite particles. The two cooperate to better prevent the composite particles from continuing to move upward and leaking through the air outlet 12.

[0032] It should be noted that the position of each fluidizing cavity 15 corresponding to the baffle 52 is expanded outward to form a slow flow cavity 16, so as to improve the pushing and dispersing effect of the baffle 52 in each fluidizing cavity 15 and further improve the fluidization effect of the composite particles in each fluidizing cavity 15.

[0033] Reference Figure 2 as well as Figure 4In some embodiments of the present application, the anti-leakage assembly 5 further includes a stirring plate, the lower end of the shaft 51 extends downward to the discharge port 13, and the stirring plate is arranged at the lower end of the shaft 51 and is used to stir the composite particles. The stirring of the stirring plate can avoid the material jamming phenomenon during the discharge.

[0034] Reference Figure 2-3 In some embodiments of the present application, the flow guide assembly 4 includes a wind shield 41 and a connecting rod 42. The wind shield 41 is arranged above the fluidized bed 3 at equal intervals along the circumference of the cylinder 1. Both ends of the connecting rod 42 are respectively connected to the wind shield 41 and the fluidized bed 3, so that the wind blown out through the blowing holes 35 on the fluidized bed 3 is blocked by the wind shield 41 to flow back and blow up the composite particles between the blowing holes 35. The hot air is redirected to the fluidized bed 3 through the wind shield 41, blowing the composite particles between the blowing holes 35 to a fluidized state, and the fluidization effect is good.

[0035] Reference Figure 3 In some embodiments of the present application, the wind shield 41 is a conical shield structure. The wind shield 41 of this structure can redirect the gas to the fluidized bed 3 at its lower end and blow up the composite particles thereon, and prevent the composite particles from accumulating at its upper end, so that the composite particles slide down to the fluidized bed 3 and are re-fluidized.

[0036] In summary, the composite particle drying device has good fluidization state, high drying effect and drying efficiency, and avoids material loss.
