Description

Technical Field

[0001] This utility model relates to the field of melamine powder processing technology, and in particular to a melamine powder drying device. Background Technology

[0002] Drying removes moisture from melamine powder, reducing problems such as product deformation, expansion, or shrinkage caused by moisture, thereby improving the dimensional stability and physical properties of the product. The dried melamine powder particles are uniform and fine, which helps to improve its solubility and processing performance, making it perform better in subsequent molding, coating and other processes.

[0003] The existing drying method involves feeding the raw material to be dried into a drying drum, introducing hot air into the drum to evaporate and remove the moisture from the raw material, and then moving the material through the internal spiral grooves of the drying drum and discharging it from the discharge port. During this movement, the raw material is piled up together. Although the raw material will turn over due to friction with the inner wall of the drying drum during rotation, the turning effect of friction is limited, and the raw material cannot fully contact the hot air. This leads to an increase in the heating time required, resulting in a waste of electricity. Utility Model Content

[0004] In order to overcome the problem that the existing melamine powder raw materials are difficult to fully contact with hot air during the drying process, which leads to an increase in the heating time and thus a waste of power resources.

[0005] The technical solution of this utility model is as follows: a melamine powder drying device, including a drying chamber body and a supporting base column, and also including a feed inlet and a feeding roller. The supporting base column is fixedly installed at the lower end of the drying chamber body, and the feed inlet is provided at the upper end of the drying chamber body. A feeding roller is rotatably arranged inside the feed inlet. A hot air fan is fixedly installed on one side of the drying chamber body, and a sliding plate is fixedly installed at the lower end of the feed inlet. A bearing seat is fixedly installed at the bottom of the drying chamber body, and a shaking plate for dispersing raw materials is rotatably connected between the two bearing seats. A venting fan for discharging moisture is provided on one side of the drying chamber body.

[0006] Preferably, the upper end of the hot air blower is fixedly connected to an air guide pipe, a fan wheel is fixedly installed on one side of the feed inlet, one end of the fan wheel's shaft is fixedly connected to one side of the feed roller, one end of the air guide pipe is set at the upper end of the fan wheel, and an air outlet pipe is fixedly connected to the lower end of the fan wheel. The air guide pipe is used to guide hot air and drive the fan wheel to rotate.

[0007] Preferably, a slide rail is fixedly installed at the bottom of the drying chamber body, a slider is slidably installed at the upper end of the slide rail, a roller frame is fixedly installed at the upper end of the slider, the roller of the roller frame contacts the lower end of the shaking plate, and the surface of the shaking plate is evenly distributed with baffles.

[0008] Preferably, a turntable is fixedly connected to one end of the shaft of the feeding roller, a connecting shaft is fixedly connected to one side of the turntable, a bevel gear is fixedly connected to one end of the connecting shaft, a support frame is fixedly installed on one side of the drying chamber body, a connecting shaft is rotatably connected to the end of the support frame, a bevel gear is fixedly connected to one end of the connecting shaft, the bevel gear and the bevel gear are meshed, and a transmission wheel is fixedly connected to the other end of the bevel gear.

[0009] Preferably, a condenser box is fixedly installed on one side of the main body of the drying chamber. A second drive wheel is rotatably installed inside the condenser box. A drive belt is provided between the first drive wheel and the second drive wheel. An exhaust fan is fixedly installed on one side of the second drive wheel and is driven by a turntable.

[0010] Preferably, a cooling water tank is fixedly installed on one side of the main body of the drying chamber, and the upper end of the cooling water tank is fixedly connected to the condensation box. The cooling water tank is used to collect the condensate in the condensation box.

[0011] Preferably, a connecting arm is rotatably connected to one side of the turntable, and one end of the connecting arm is rotatably connected to one side of the slider, which is driven to move by the connecting arm.

[0012] The beneficial effects of this utility model are:

[0013] 1. During the hot air injection process, the melamine powder drying device uses the flow of hot air to drive the lower turntable to rotate. The turntable drives the shaking plate to flip at the same time through the connecting arm. During the flipping process, one end of the shaking plate will collide with the end of the sliding plate, thereby generating vibration. This causes the raw material on the surface of the shaking plate to be continuously dispersed and spread out. In this way, the contact area between the raw material on the surface of the shaking plate and the hot air will be larger, thus increasing the heating rate.

[0014] 2. This melamine powder drying device also uses hot air flow to drive the exhaust fan to draw out the moisture, which saves energy. After the high-temperature moisture is drawn out, it enters the condensation box. Some of the moisture condenses into liquid and falls into the cooling water tank below. The cooling water tank dissipates heat from the hot air blower, preventing the hot air blower from overheating in hot weather and reducing its service life. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5 This utility model provides an embodiment: a melamine powder drying device, including a drying chamber body 1 and a supporting base column 2, and also including a feed inlet 3 and a feeding roller 4. The supporting base column 2 is fixedly installed at the lower end of the drying chamber body 1, and the feed inlet 3 is provided at the upper end of the drying chamber body 1. The feeding roller 4 is rotatably arranged inside the feed inlet 3. A hot air fan 5 is fixedly installed on one side of the drying chamber body 1, and a sliding plate 9 is fixedly installed at the lower end of the feed inlet 3. A bearing seat 10 is fixedly installed at the bottom of the drying chamber body 1, and a shaking plate for dispersing raw materials is rotatably connected between the two bearing seats 10. 11. A venting fan 25 for exhausting moisture is provided on one side of the main body 1 of the drying chamber. During the hot air injection process, the melamine powder drying device drives the lower turntable 16 to rotate by the flow of hot air. The turntable 16 drives the shaking plate 11 to flip at the same time through the connecting arm 26. During the flipping process, one end of the shaking plate 11 will collide with the end of the sliding plate 9, thereby playing a vibration role. This causes the raw material on the surface of the shaking plate 11 to be continuously dispersed and spread out. In this way, the contact area between the raw material on the surface of the shaking plate 11 and the hot air will be larger, thus improving the heating rate.

[0023] Please see Figure 2 and Figure 3In this embodiment, a guide pipe 6 is fixedly connected to the upper end of the hot air blower 5, a fan wheel 7 is fixedly installed on one side of the feed inlet 3, one end of the rotating shaft of the fan wheel 7 is fixedly connected to one side of the feeding roller 4, one end of the guide pipe 6 is located at the upper end of the fan wheel 7, and an air outlet pipe 8 is fixedly connected to the lower end of the fan wheel 7. The guide pipe 6 is used to guide hot air and drive the fan wheel 7 to rotate. A slide rail 12 is fixedly installed at the bottom of the drying chamber body 1, a slider 13 is slidably arranged at the upper end of the slide rail 12, a roller frame 14 is fixedly installed at the upper end of the slider 13, the roller shaft of the roller frame 14 contacts the lower end of the shaking plate 11, and baffles 15 are evenly distributed on the surface of the shaking plate 11. A connecting arm 26 is rotatably connected to one side of the turntable 16, and one end of the connecting arm 26 is rotatably connected to one side of the slider 13. The slider 13 is driven to move by the connecting arm 26. In use, the raw material is first fed into the feed inlet. In port 3, the hot air blower 5 is turned on. The hot air from the hot air blower 5 is injected into the main body 1 of the drying chamber through the air guide pipe 6. During the injection of hot air, the impeller 7 is driven to rotate by the hot air, and the feeding roller 4 rotates at the same time. During the rotation of the feeding roller 4, the raw material is discharged in a certain amount and falls onto the sliding plate 9. Then, it slides down the sliding plate 9 onto the surface of the shaking plate 11. During the rotation of the turntable 16, the roller frame 14 is moved simultaneously through the connecting arm 26. During the reciprocating motion of the roller frame 14, the shaking plate 11 in contact with the roller frame 14 is flipped at the same time. During the flipping process, one end of the shaking plate 11 will collide with the end of the sliding plate 9, thereby playing a vibration role. This causes the raw material on the surface of the shaking plate 11 to be continuously dispersed and spread out. In this way, the contact area between the raw material on the surface of the shaking plate 11 and the hot air will be larger, thus increasing the heating rate.

[0024] Please see Figure 1 and Figure 4In this embodiment, a turntable 16 is fixedly connected to one end of the shaft of the feeding roller 4. A connecting shaft 17 is fixedly connected to one side of the turntable 16. A bevel gear 18 is fixedly connected to one end of the connecting shaft 17. A support frame 19 is fixedly installed on one side of the drying chamber body 1. A connecting shaft 20 is rotatably connected to the end of the support frame 19. A bevel gear 21 is fixedly connected to one end of the connecting shaft 20. The bevel gear 18 and the bevel gear 21 mesh with each other. A transmission wheel 22 is fixedly connected to the other end of the bevel gear 21. A condenser box 27 is fixedly installed on one side of the drying chamber body 1. A transmission wheel 24 is rotatably arranged inside the condenser box 27. A transmission belt 23 is provided between the transmission wheel 1 22 and the transmission wheel 24. A duct fan 25 is fixedly installed on one side of the transmission wheel 24. Driven by the turntable 16, a cooling water tank 28 is fixedly installed on one side of the drying chamber body 1. The upper end of the cooling water tank 28 is fixedly connected to the condensation box 27. The cooling water tank 28 is used to collect the condensate in the condensation box 27. During the rotation of the turntable 16, the connecting shaft 20 rotates at the support frame 19. The transmission wheel 22 at one end of the connecting shaft 20 drives the transmission wheel 24 to rotate through the transmission belt 23. The exhaust fan 25 fixedly connected to one side of the transmission wheel 24 rotates at the same time to draw moisture out from the drying chamber body 1. After the high temperature moisture is drawn out, it enters the condensation box 27. After some moisture condenses into liquid, it falls into the cooling water tank 28 below. The cooling water tank 28 dissipates heat for the hot air blower 5 to prevent the hot air blower 5 from overheating in hot weather, which would reduce its service life.

[0025] During use, the raw material is first fed into the feed inlet 3, and the hot air blower 5 is turned on. The hot air from the hot air blower 5 is injected into the main body 1 of the drying chamber through the air guide pipe 6. During the injection of hot air, the impeller 7 is driven to rotate by the hot air. One end of the shaft of the impeller 7 is fixedly connected to the feeding roller 4. The feeding roller 4 rotates simultaneously, and during the rotation, the feeding roller 4 discharges a fixed amount of raw material and drops it onto the sliding plate 9. Then, it slides down the sliding plate 9 onto the surface of the shaking plate 11. One end of the shaft of the feeding roller 4 is fixedly connected to the turntable 16. During the rotation of the turntable 16, the connecting arm 26 drives the slider 13 to move at the slide rail 12. The upper end of the slider 13 is fixedly installed with... The roller frame 14 moves simultaneously. During the reciprocating motion of the roller frame 14, the shaking plate 11, which is in contact with the roller frame 14, rotates at the bearing seat 10, thereby achieving a flipping action. During the flipping process, one end of the shaking plate 11 will collide with the end of the sliding plate 9, thereby achieving a vibration effect, causing the raw material on the surface of the shaking plate 11 to be continuously dispersed and spread out. In this way, the contact area between the raw material on the surface of the shaking plate 11 and the hot air will be larger, which will increase the heating rate. The dried raw material is discharged from the discharge port at the lower end of the drying chamber body 1. The baffle 15 is used to slow down the movement speed of the raw material to ensure that the raw material has enough time to disperse.

[0026] During the rotation of turntable 16, connecting shaft 17, which is fixedly connected to one side of turntable 16, rotates simultaneously. Bevel gear 18 at one end of connecting shaft 17 drives bevel gear 21 to rotate. Bevel gear 21 is fixedly connected to one end of connecting shaft 20. Connecting shaft 20 rotates at the support frame 19. Transmission wheel 22 at one end of connecting shaft 20 drives transmission wheel 24 to rotate simultaneously via transmission belt 23. Drainage fan 25, which is fixedly connected to one side of transmission wheel 24, rotates simultaneously to draw moisture out of the drying chamber body 1. The flow of hot air drives the drainage fan 25 to draw out moisture, saving energy.

[0027] After the high-temperature and humid air is drawn out, it enters the condensation box 27. Some of the humid air condenses into liquid and falls into the cooling water tank 28 below. The cooling water tank 28 dissipates heat from the hot air blower 5 to prevent the hot air blower 5 from overheating in hot weather, which would reduce its service life.

[0028] Through the above steps, during the hot air injection process, the melamine powder drying device uses the flow of hot air to drive the lower turntable 16 to rotate. The turntable 16 drives the shaking plate 11 to flip at the same time through the connecting arm 26. During the flipping process, one end of the shaking plate 11 will collide with the end of the sliding plate 9, thereby playing a vibration role. This causes the raw material on the surface of the shaking plate 11 to be continuously dispersed and spread out. In this way, the contact area between the raw material on the surface of the shaking plate 11 and the hot air will be larger, thus improving the heating rate.
