Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a flash drying device with a dispersion mechanism. Background Technique

[0002] A flash dryer is a device composed of an electric heating device, an air heater, a condenser, an exhaust steam device, an impeller fan and a control system. Its working principle is to heat the air by using the electric heating device to make the air temperature reach the evaporation temperature, evaporate heat, make the temperature of the material rise, and evaporate the moisture in the material to achieve the purpose of drying.

[0003] At present, the common flash dryers on the market mainly consist of a heater, a feeder, a drying box and a cyclone separator, which can perform functions such as drying, pulverizing and screening on materials. Due to its high-efficiency and fast drying characteristics, the flash dryer is applicable to various types of materials, including paste-like, slurry-like, filter cake and other materials. However, there are some inconveniences in actual operation and there is certain room for improvement. For example, when viscous materials enter the dryer for drying, usually only rely on the blower to heat the air and then send the hot air into the dryer. When the high-temperature air enters the bottom of the dryer, it is sprayed upward at high speed through the nozzle, and the material is blown up by the high-temperature air flow and dispersed under the action of impact friction and shear stress. The pulverized small particles are discharged outside the dryer, and the large particles continue to circulate and be pulverized. The pulverizing form of the material is relatively single and the pulverizing speed always remains stable. There is no additional dispersion mechanism to further pulverize and refine it, and it does not have the function of accelerating the dispersion of the material.

[0004] Now, a new type of flash drying device with a dispersion mechanism is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flash drying device with a dispersion mechanism to solve the problem of lacking the function of accelerating the dispersion of materials proposed in the above background technique.

[0007] The limiting component includes two groups of limiting blocks, and the two groups of limiting blocks are respectively fixedly connected to the left and right sides of the inner bottom end of the dryer. On one side of the limiting block close to the conical disk, there are multiple groups of first convex strips. On the outer side of the conical disk, there are multiple groups of second convex strips. A pulley is arranged at the bottom end of the dryer, a second motor is arranged outside the pulley, and a transmission shaft is arranged inside the pulley.

[0008] Preferably, the vertical center lines of the conical disk, the transmission shaft, and the dryer coincide, and the limiting blocks are symmetrically distributed about the vertical center line of the conical disk.

[0009] Preferably, the first convex strips and the second convex strips are arranged at equal intervals, the first convex strips and the second convex strips are made of the same material, and there is a distance between the first convex strips and the second convex strips.

[0010] Preferably, the positions of the conical disk and the limiting blocks correspond one by one, and there is a distance between the conical disk and the limiting blocks.

[0011] Preferably, a heat insulation housing is sleeved outside the screw feeder. A graphite sleeve is arranged inside the heat insulation housing, a disk-shaped heating coil is arranged outside the graphite sleeve, a power cord is arranged at the bottom end of the heat insulation housing, and a controller is arranged below the power cord.

[0012] Preferably, the shape and size of the outside of the graphite sleeve are adapted to the shape and size of the inside of the disk-shaped heating coil. The graphite sleeve and the disk-shaped heating coil are closely attached. The heat insulation housing is movably connected to the graphite sleeve and the disk-shaped heating coil. The horizontal center lines of the heat insulation housing, the graphite sleeve, the disk-shaped heating coil, and the second motor coincide.

[0013] Preferably, a vibrating body is arranged outside the feed hopper. Connecting flanges are respectively arranged at the upper and lower ends of the vibrating body. Three connecting studs are arranged between the upper and lower ends of the connecting flanges. Three nuts are respectively arranged at the top and bottom ends of the connecting flanges. A vibrating motor is arranged on the right side of the vibrating body.

[0014] Preferably, the positions of the nuts and the connecting studs correspond one by one. The shape and size of the inside of the vibrating body are adapted to the shape and size of the outside of the feed hopper. The vibrating motor is electrically connected to the vibrating body.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The flash drying device with a dispersion mechanism not only realizes the function of accelerating the dispersion of materials, but also realizes the function of heating and refining materials, and also realizes the function of preventing material adhesion;

[0016] (1) By setting up a second motor, a pulley, a transmission shaft, a limiting block, a first rib, and a second rib, fresh air enters the heater through a blower to form hot air and then enters the bottom of the dryer. Driven by the second motor, a powerful rotating air field is formed. The material enters the dryer through a screw feeder. The pulley driven by the second motor drives the transmission shaft to drive the conical disk to rotate. Under the strong action of the high-speed rotating conical disk, the material is dispersed under the action of impact, friction, and shear force. The massive material is quickly crushed. At this time, it is in full contact with the hot air, heated, and dried. The obtained dried material is collected from the top of the dryer into a cyclone separator for further screening. The material that is not completely dry or large pieces is thrown towards the wall of the device under the action of centrifugal force and falls back to the bottom to be crushed and dried again. When the material is suspended and impacts between the conical disk and the limiting block, the first rib on the limiting block and the second rib outside the conical disk further refine and disperse the material in the dryer, accelerating the dispersion speed of the material and improving the efficiency of material drying and dispersion, realizing the function of accelerating the dispersion of materials;

[0017] (2) By setting up a heat-insulating shell, a graphite sleeve, a disc-shaped heating coil, a power cord, and a controller, before the material is fed into the dryer, it usually enters the screw feeder through a feed hopper first. The screw agitator in the screw feeder feeds the material into the dryer for crushing and dispersion. When the material is fed into the screw feeder again, the graphite sleeve outside the screw feeder can generate heat through the disc-shaped heating coil sleeved outside. The graphite sleeve transfers the heat to the inside of the screw feeder, so that the material to be conveyed is heated and further refined before entering the dryer. The heat-insulating shell isolates the heat of the disc-shaped heating coil inside from the outside to prevent high-temperature burns. After the power cord is energized, the operator can freely control the heating temperature through the controller to avoid the possibility of damaging the material due to excessive temperature, realizing the function of heating and refining the material;

[0018] (3) By setting up a connecting flange, a vibration motor, a nut, a connecting stud, and a vibrating body, after the material is added from the feed hopper to the screw feeder, it is sent to the dryer by the screw agitator for drying and crushing. When viscous paste-like, slurry-like and other materials are fed into the feed hopper, the vibration motor drives the vibrating body outside the feed hopper to vibrate. The vibrating body is connected to the feed hopper through the connecting flange, and then the vibrating body is fixed outside the feed hopper by the nut and the connecting stud. The feed hopper reciprocally twists and vibrates up and down under the support of the connecting stud to realize automatic feeding of the material. The exciting force generated by the vibration motor makes the material in the hopper vibrate periodically in the vertical direction, which can effectively loosen the material and enhance its fluidity, thus making it more convenient for the transportation and feeding of the material. Through vibration, the material in the feed hopper is activated, reducing the occurrence of material blockage and sticking in the bin, realizing the function of preventing material adhesion.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1: Please refer to Figures 1-5 , a flash drying device with a dispersion mechanism, including a dryer 1, a base 2 is fixedly connected to the bottom end of the dryer 1, a blower 4 is arranged to the left of the dryer 1, a heater 3 is movably connected between the right side of the blower 4 and the left side of the dryer 1, a cyclone separator 5 is arranged above the dryer 1, a screw feeder 7 is arranged to the right of the dryer 1, a feed hopper 6 is arranged at the top end of the screw feeder 7, a first motor 8 is arranged at the bottom end of the screw feeder 7, a conical disk 12 is arranged at the bottom end inside the dryer 1, and limit components for accelerating the dispersion of materials are fixedly connected to the left and right sides at the bottom end inside the dryer 1;

[0027] Please refer to Figures 1-5, A flash drying device with a dispersion mechanism further includes a limiting component. The limiting component includes two groups of limiting blocks 13, which are respectively fixedly connected to the left and right sides of the inner bottom end of the dryer 1. On one side of the limiting block 13 close to the conical disk 12, there are multiple groups of first convex strips 14. On the outside of the conical disk 12, there are multiple groups of second convex strips 15. At the bottom end of the dryer 1, there is a pulley 10. Outside the pulley 10, there is a second motor 9. Inside the pulley 10, there is a transmission shaft 11;

[0028] The vertical center lines of the conical disk 12, the transmission shaft 11, and the dryer 1 coincide. The limiting blocks 13 are symmetrically distributed about the vertical center line of the conical disk 12. The first convex strips 14 and the second convex strips 15 are arranged at equal intervals. The first convex strips 14 and the second convex strips 15 are made of the same material. There is a distance between the first convex strips 14 and the second convex strips 15. The positions of the conical disk 12 and the limiting blocks 13 correspond one by one. There is a distance between the conical disk 12 and the limiting blocks 13;

[0029] Specifically, as Figure 1 and Figure 2 shown, fresh air enters the heater 3 through the blower 4 to form hot air and then enters the bottom of the dryer 1, forming a strong rotating wind field driven by the second motor 9. The material enters the dryer 1 through the screw feeder 7. The second motor 9 drives the pulley 10 to make the transmission shaft 11 drive the conical disk 12 to rotate. Under the strong action of the rapidly rotating conical disk 12, the material is dispersed under the action of impact, friction, and shear force. The massive material is quickly crushed. At this time, it is in full contact with the hot air, heated, and dried. The obtained dried material is collected from the top of the dryer 1 into the cyclone separator 5 for further screening. The undried or large pieces of material are thrown towards the wall of the device under the action of centrifugal force and fall back to the bottom to be crushed and dried again. When the material is suspended and impacts between the conical disk 12 and the limiting blocks 13, the first convex strips 14 on the limiting blocks 13 and the second convex strips 15 outside the conical disk 12 further refine and disperse the material in the dryer 1, accelerating the dispersion speed of the material, and the material can be further dispersed and refined.

[0030] Embodiment 2: An insulating outer shell 16 is sleeved outside the screw feeder 7. Inside the insulating outer shell 16, there is a graphite sleeve 17. Outside the graphite sleeve 17, there is a disc-shaped heating coil 18. At the bottom end of the insulating outer shell 16, there is a power cord 19. Below the power cord 19, there is a controller 20. The shape and size of the outside of the graphite sleeve 17 are adapted to the shape and size of the inside of the disc-shaped heating coil 18. The graphite sleeve 17 and the disc-shaped heating coil 18 are closely fitted. The insulating outer shell 16 is movably connected to the graphite sleeve 17 and the disc-shaped heating coil 18. The horizontal center lines of the insulating outer shell 16, the graphite sleeve 17, the disc-shaped heating coil 18, and the second motor 9 coincide;

[0031] Specifically, as Figure 1 , Figure 3 andFigure 4 As shown, before the material is fed into the dryer 1, it usually enters the screw feeder 7 from the feed hopper 6 first. The screw agitator in the screw feeder 7 feeds the material into the dryer 1 for crushing and dispersion. After the material is fed into the screw feeder 7 again, the graphite sleeve 17 outside the screw feeder 7 can generate heat through the disk-shaped heating coil 18 sleeved outside. The graphite sleeve 17 transfers the heat to the inside of the screw feeder 7, so that the conveyed material is heated and further refined before entering the dryer 1. The heat of the internal disk-shaped heating coil 18 is isolated from the outside through the heat-insulating outer shell 16 to prevent high-temperature burns. After the power cord 19 is energized, the operator can freely control the heating temperature through the controller 20, improving the drying efficiency of the material.

[0032] Embodiment 3: A vibrator 25 is arranged outside the feed hopper 6. Connecting flanges 21 are respectively arranged at the upper and lower ends of the vibrator 25. Three groups of connecting studs 24 are arranged between the upper and lower ends of the connecting flange 21. Three groups of nuts 23 are respectively arranged at the top and bottom of the connecting flange 21. A vibration motor 22 is arranged on the right side of the vibrator 25. The positions of the nuts 23 and the connecting studs 24 correspond one by one. The shape and size inside the vibrator 25 are adapted to the shape and size outside the feed hopper 6. The vibration motor 22 is electrically connected to the vibrator 25;

[0033] Specifically, as Figure 1 and Figure 4 shown, after the material is added from the feed hopper 6 to the screw feeder 7, it is sent into the dryer 1 by the screw agitator for drying and crushing. When viscous paste-like, slurry-like and other materials are fed into the feed hopper 6, the vibrator 25 outside the feed hopper 6 is driven by the vibration motor 22 to vibrate. The vibrator 25 and the feed hopper 6 are connected through the connecting flange 21, and then the vibrator 25 is fixed outside the feed hopper 6 by the nuts 23 and the connecting studs 24. The feed hopper 6 reciprocally twists and vibrates up and down under the support of the connecting studs 24, realizing automatic feeding of the material. The exciting force generated by the vibration motor 22 makes the material in the hopper vibrate periodically in the vertical direction, which can effectively loosen the material and enhance its fluidity. The material in the feed hopper 6 is activated through vibration, preventing material blockage and sticking in the bin, and making it more convenient for material transportation and feeding.

[0034] Working principle: When the utility model is in use, first, fresh air enters the heater 3 through the blower 4 to form hot air and then enters the bottom of the dryer 1. Driven by the second motor 9, a strong rotating air field is formed. The material enters the dryer 1 through the screw feeder 7. The second motor 9 drives the pulley 10, and the transmission shaft 11 drives the conical disk 12 to rotate. Under the strong action of the conical disk 12 rotating at high speed, the material is dispersed under the action of impact, friction and shear force. The massive material is quickly crushed. At this time, it is in full contact with the hot air, heated and dried. The obtained dried material is collected into the cyclone separator 5 from the top of the dryer 1 for further screening. The material that is not thoroughly dried or is in large chunks is thrown towards the wall of the device under the action of centrifugal force and falls back to the bottom to be crushed and dried again. After the material is suspended, it impacts between the conical disk 12 and the limit block 13. The first rib 14 on the limit block 13 and the second rib 15 outside the conical disk 12 further refine and disperse the material in the dryer 1, accelerating the dispersion speed of the material, and the material can be further dispersed and refined. Before the material is fed into the dryer 1, it usually enters the screw feeder 7 from the feed hopper 6 first. The screw agitator in the screw feeder 7 feeds the material into the dryer 1 for crushing and dispersion. After the material is fed into the screw feeder 7 again, the graphite sleeve 17 outside the screw feeder 7 can generate heat through the disk-shaped heating coil 18 sleeved on the outside. The graphite sleeve 17 transfers the heat to the inside of the screw feeder 7, so that the conveyed material is heated and further refined before entering the dryer 1. The heat of the internal disk-shaped heating coil 18 is isolated from the outside through the heat-insulating housing 16 to prevent high-temperature burns. After the power cord 19 is energized, the operator can freely control the heating temperature through the controller 20, improving the drying efficiency of the material. After the material is added from the feed hopper 6 to the screw feeder 7, it is sent to the dryer 1 by the screw agitator for drying and crushing. When viscous paste-like, slurry-like and other materials are fed into the feed hopper 6, the vibration motor 22 drives the vibrator 25 outside the feed hopper 6 to vibrate. The vibrator 25 and the feed hopper 6 are connected through the connecting flange 21, and then the vibrator 25 is fixed outside the feed hopper 6 by the nut 23 and the connecting stud 24. The feed hopper 6 reciprocally twists and vibrates up and down under the support of the connecting stud 24 to realize automatic feeding of the material. The exciting force generated by the vibration motor 22 causes the material in the hopper to vibrate periodically in the vertical direction, which can effectively loosen the material and enhance its fluidity. The vibration activates the material in the feed hopper 6, preventing material blockage and sticking in the bin, and making it more convenient for material conveying and feeding.
