Description

Technical Field

[0001] The present invention belongs to the technical field of Fischer-Tropsch wax production, and particularly relates to a continuous drying device for Fischer-Tropsch wax production. Background Art

[0002] Fischer-Tropsch wax is a malleable synthetic sealing material, usually used for the encapsulation of electronic components. Its production process mainly includes steps such as raw material selection, mixing and melting, refining and filtering, compounding and pressing, forming and curing, etc. Among them, Fischer-Tropsch wax usually cures from the outside to the inside during forming and curing, so it is easy to leave some moisture inside. In order to solve the problem that moisture remains inside the Fischer-Tropsch wax due to the too fast solidification speed of the outer layer, before the Fischer-Tropsch wax solidifies, it is necessary to perform a drying treatment on the solution of the Fischer-Tropsch wax to remove the moisture inside the Fischer-Tropsch wax and ensure the internal quality of the Fischer-Tropsch wax. In the existing Fischer-Tropsch wax production process, this step and the process for performing this step are often lacking, resulting in the production quality of Fischer-Tropsch wax not being guaranteed.

The lower end of the air supply pipe is rotationally matched with the aeration cylinder. The upper end of the air supply pipe is connected to a hot gas supply device.

[0006] Further, a pressing block is slidably installed inside the aeration cylinder at one end inside the aeration cylinder.

[0008] Further, there are multiple groups of the pressing pieces and springs. Adjacent pressing pieces are connected through springs.

[0009] Further, a plurality of limiting plates are fixed around the pressing piece. The limiting plates are slidably arranged in the strip-shaped grooves.

[0010] Further, the rotation driving device includes a first gear, a second gear and a first motor. The first gear is coaxially fixed at the lower end of the aeration cylinder. The first gear meshes with the second gear. The first gear and the second gear are simultaneously rotationally connected to a disc. The second gear is connected to the output end of the first motor.

[0011] Further, the revolution driving device includes a third gear, a second motor and a toothed ring. The toothed ring is fixed on the inner wall of the air-blowing net cylinder.

[0012] Further, a first limiting ring and a second limiting ring are simultaneously fixed at the bottom of the air-blowing net cylinder. An annular slideway for the sliding fit of the first motor is formed between the first limiting ring and the second limiting ring with a space therebetween.

[0013] Further, the air-blowing net cylinder is fixedly connected to a slider. The slider is slidably arranged in a vertical track.

[0015] In the continuous drying device for producing Fischer-Tropsch wax of the present invention, during use, the air-blowing cylinder is placed in a solution storage tank filled with Fischer-Tropsch wax solution. The aeration cylinder inside the air-blowing cylinder can continuously generate a large number of bubbles, which can promptly carry out the moisture in the Fischer-Tropsch wax solution, ensuring the internal quality of the Fischer-Tropsch wax. Since the hot bubbles are lighter in weight and are more likely to overflow from the solution than water vapor, and the device of the present invention introduces hot air, which also avoids the residue of bubbles or moisture in the solution.

[0016] In the drying device disclosed by the present invention, the hot air can further prevent the solidification of the Fischer-Tropsch wax solution, and also improve the activity of the bubbles, making it easier for the bubbles to evaporate the moisture together, reducing the residue of moisture. Through the action of revolution and rotation, the bubbles can be fully aerated in the solution, so that the moisture can be removed more thoroughly.

Detailed implementation manners

[0026] As Figures 1 to 6 shown, a continuous drying device for Fischer-Tropsch wax production according to the present invention includes a solution storage tank 1 and a drying assembly 2 installed in the solution storage tank 1. The solution storage tank 1 is filled with a solution of Fischer-Tropsch wax. The drying assembly 2 can move in the solution storage tank 1 through a connecting displacement device, and at different heights or planar positions, the Fischer-Tropsch wax solution at various places in the solution storage tank 1 can be dried and evaporated.

[0027] Specifically, the drying assembly 2 of the present invention includes an air-blowing mesh cylinder 3. The air-blowing mesh cylinder 3 is in a cylindrical shape, and a plurality of mesh holes are opened on the outer side of the air-blowing mesh cylinder 3 for the reciprocating flow of the Fischer-Tropsch wax solution. A revolution driving device is installed in the air-blowing mesh cylinder 3, and the output end of the revolution driving device is connected with a rotation driving device. The revolution driving device drives the rotation driving device to rotate around the axis of the air-blowing mesh cylinder 3. The output end of the rotation driving device is connected with an aeration cylinder 4. The aeration cylinder 4 is also in a cylindrical shape. The rotation driving device can drive the aeration cylinder 4 to rotate around its own axis. Through combination with the revolution driving device, the aeration cylinder 4 can perform revolution and rotation in the air-blowing mesh cylinder 3 to increase the aeration area and efficiency.

[0028] The aeration cylinder 4 is close to the inner wall of the air-blowing mesh cylinder 3. The axes of the aeration cylinder 4 and the air-blowing mesh cylinder 3 are both along the vertical direction. A plurality of strip-shaped grooves 5 are axially opened on the surface of the aeration cylinder 4. A central coaxial rotation setting of an aeration pipe 6 is arranged in the aeration cylinder 4. A plurality of aeration holes 7 are opened on the aeration pipe 6. The aeration holes 7 are evenly spaced along the axis. The lower end of the aeration pipe 6 is rotationally matched with the aeration cylinder 4, and the upper end of the aeration pipe 6 is connected to a hot gas supply device. The hot gas supply device includes a hot air blower and a pipeline. An air pump is connected to the pipeline, and gas can be continuously introduced into the aeration pipe 6 through the pipeline.

[0029] In this embodiment, a pressing block 8 is slidably installed in the aeration cylinder 4. One end of the pressing block 8 located inside the aeration cylinder 4 is filled with filter cotton in the cavity separated from the other end of the aeration cylinder 4. The pressing block 8 is cylindrical. The outer surface of the pressing block 8 is in sliding fit with the inner side surface of the aeration cylinder 4. A spiral guide groove 9 is formed on the outer circumferential surface of the pressing block 8, and a pin shaft 10 slidably engaged with the guide groove 9 is fixed on the inner wall of the aeration cylinder 4. When the aeration cylinder 4 rotates back and forth, the aeration cylinder 4 drives the pin shaft 10 to rotate. The pin shaft 10 can drive the pressing block 8 to move along the axial direction of the aeration cylinder 4 through the cooperation of the guide groove 9, so that the inner cavity of the aeration cylinder 4 can be continuously compressed, and the hot air can be quickly dissipated from the aeration cylinder 4, which is more beneficial to taking out the water vapor in the Fischer-Tropsch wax. At the same time, when a pumping effect of negative pressure is generated in the aeration cylinder 4, the Fischer-Tropsch wax solution continuously enters and exits the aeration cylinder 4. Through the filtering effect of the filter cotton, a little impurity can be adsorbed, achieving a certain filtering effect and improving the manufacturing quality of the Fischer-Tropsch wax.

[0030] In this embodiment, the end face of the pressing block 8 is connected with a pressing piece 12 through a spring 11. The cooperation between the pressing pieces 12 can also compress the filter cotton. The back-and-forth movement of the pressing piece 12 can make the pumping effect of the hot air better. The pressing piece 12 is slidably arranged in the aeration cylinder 4. A central hole 13 matched with the aeration pipe 6 is formed in the center of the pressing piece 12 to achieve sliding fit. A plurality of through holes 14 are formed in the pressing piece 12 to facilitate the easy passage of the Fischer-Tropsch wax. A protective ring 15 matched with the pressing piece 12 is fixed on the end face of the pressing block 8 to reduce the damage to the surface of the pressing block 8. There are multiple groups of the pressing piece 12 and the spring 11. Adjacent pressing pieces 12 are connected through the spring 11. The spring 11 provides an elastic restoring force for the pressing piece 12, so that the pressing piece 12 can return to its original position in time when not in use.

[0031] In this embodiment, a plurality of limiting plates 16 are fixed around the pressing piece 12. The limiting plates 16 are slidably arranged in the strip-shaped groove 5. The cooperation between the limiting plates 16 and the strip-shaped groove 5 can play a guiding role in the moving direction of the pressing piece 12 to prevent the pressing piece 12 from deflecting.

[0032] In this embodiment, the rotation driving device includes a first gear 17, a second gear 18 and a first motor 19. The first gear 17 is coaxially fixed at the lower end of the aeration cylinder 4. The first gear 17 meshes with the second gear 18. The first gear 17 and the second gear 18 are both rotatably connected to a disc 20. The second gear 18 is connected to the output end of the first motor 19. When the first motor 19 rotates, it can drive the second gear 18 to rotate. The second gear 18 drives the first gear 17 to rotate, and the first gear 17 drives the aeration cylinder 4 to rotate. After the drying device is used up, the drying device can be taken out of the solution storage tank 1 to prevent interference with the solidification process of the Fischer-Tropsch wax.

[0033] In this embodiment, the revolution driving device includes a third gear 21, a second motor 22 and a gear ring 23. The gear ring 23 is fixed to the inner wall of the air blowing cylinder 3. The gear ring 23 meshes with the third gear 21. The third gear 21 is connected to the output end of the second motor 22. The second motor 22 is fixed on the disc 20. By providing the revolution driving device, the aeration cylinder 4 can be rotated around the axis of the air blowing cylinder 3, making the driving more convenient.

[0034] In this embodiment, a first limiting ring 24 and a second limiting ring 25 are simultaneously fixed to the bottom of the air blowing cylinder 3. An annular slideway 26 for the sliding fit of the first motor 19 is formed between the first limiting ring 24 and the second limiting ring 25, providing a sliding track for the first motor 19 and preventing the device from coming off.

[0035] In this embodiment, the air blowing cylinder 3 is fixedly connected to a slider 27. The slider 27 is slidably arranged in a vertical track 28. The upper end of the vertical track 28 is fixedly connected to a support 29. A third motor 30 is installed on the support 29. The slider 27 is simultaneously threadedly connected to a screw rod 31. The upper end of the screw rod 31 is connected to the output end of the third motor 30. By providing the third motor 30, the slider 27 and the air blowing cylinder 3 connected thereto can be driven to move up and down. The support 29 is fixedly connected to a longitudinal slide bar 32. The longitudinal slide bar 32 is slidably mated with a slide seat 33. A first rack 34 is installed on the longitudinal slide bar 32. The first rack 34 meshes with a fourth gear 35. The fourth gear 35 is connected to a fourth motor 36 fixed on the slide seat 33. The slide seat 33 is simultaneously slidably mated with a transverse slide bar 37. The two ends of the transverse slide bar 37 are fixedly connected to a base 38. The base 38 is fixed on the upper side of the solution storage tank 1. A fifth motor 39 is fixed on the slide seat 33. The output end of the fifth motor 39 is connected to a fifth gear 40. The fifth gear 40 meshes with a second rack 41 fixed on the base 38. By providing the above structure, the air blowing cylinder 3 can be driven to move in a plane, so as to achieve the purpose of drying the Fischer-Tropsch wax at different positions.
