Description

Technical Field

[0001] This invention relates to the field of ribbon dryer technology, and more particularly to a multi-purpose corrosion-resistant conical ribbon dryer. Background Technology

[0002] Conical ribbon dryers, due to their compact structure, uniform mixing, and high heat transfer efficiency, have been widely used in the drying of powders or pastes in chemical, pharmaceutical, food, and new energy fields. Especially when processing heat-sensitive, easily oxidized, high-viscosity, or solvent-containing materials, the conical ribbon dryer demonstrates excellent integrated drying and mixing capabilities thanks to the self-flowing characteristics of its conical cylinder and the forced convection effect of the ribbon agitation.

[0003] However, as production processes increasingly demand higher levels of drying efficiency, product quality, energy utilization, and equipment versatility, existing conical ribbon dryers have gradually revealed the following shortcomings in terms of technical performance:

[0004] 1. Single temperature control for drying, which poses a risk of moisture reabsorption: Traditional equipment often uses single-temperature jacket heating, so the material is always in a high-temperature environment inside the drying drum. After drying, the material temperature is still high. After being discharged, it comes into contact with the low-temperature and high-humidity air outside, which makes it very easy to absorb moisture and reabsorb moisture, which seriously affects the drying effect and the storage stability of the product.

[0005] 2. Low thermal energy utilization efficiency and high energy consumption: Existing equipment typically only has one heating chamber, and the high-temperature heat medium is directly discharged or recycled after drying, failing to fully utilize its remaining heat energy. Especially under multi-stage drying requirements, it is impossible to achieve cascade utilization of heat energy, resulting in low overall energy utilization efficiency;

[0006] 3. Lack of particle size control and grading functions: Traditional conical ribbon dryers cannot simultaneously grade and screen materials during the drying process. The particle size distribution of the dried material is uneven, and additional screening equipment is still required, which increases the complexity of the process and the cost of equipment investment.

[0007] 4. Limited functionality, making it difficult to meet the integrated needs of modification and other processes: Existing equipment mainly focuses on drying operations, making it difficult to simultaneously complete process operations such as material modification, coating, or additive mixing during the drying process, thus limiting the equipment's multi-purpose expansion capabilities.

[0008] Therefore, we propose a multi-purpose corrosion-resistant conical ribbon dryer. Summary of the Invention

[0009] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-purpose corrosion-resistant conical ribbon dryer.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A multi-purpose corrosion-resistant conical ribbon dryer, comprising:

[0012] The top cover of the dryer has a conical drying cylinder at its lower part. The inner wall of the conical drying cylinder has a primary drying oil chamber and several sets of progressively low-temperature drying oil chambers from top to bottom. The primary drying oil chamber, the progressively low-temperature drying oil chambers, and adjacent progressively low-temperature drying oil chambers are separated by a partition strip. The partition strip is equipped with a connecting oil pump, which is used to pump the high-temperature oil in the upper primary drying oil chamber or the progressively low-temperature drying oil chamber to the lower progressively low-temperature drying oil chamber for further drying at a lower temperature.

[0013] The conical drying cylinder has a sieve plate in the middle and a guide plate on the upper part of the sieve plate. The sieve plate and the guide plate set the upper part of the inner cavity of the conical drying cylinder as the preliminary drying zone, which corresponds to the primary drying oil chamber. The lower part of the inner cavity is set as the graded low-temperature drying zone. In the low-temperature drying zone, there are several sets of step-by-step material dropping plates and agitators corresponding to each step of the low-temperature drying oil chamber. These are used to grade and screen the material being dried step by step, ensuring that the material is discharged at a lower temperature while drying, thus reducing the phenomenon of re-moistening caused by high material discharge temperature and low humidity.

[0014] A rotating shaft is fixedly installed at the center of the conical drying cylinder. The conical drying cylinder has a bonding spiral ribbon and a rack and pinion spiral ribbon in the preliminary drying zone. The bonding spiral ribbon and the rack and pinion spiral ribbon are fixedly connected to the rotating shaft through a connecting rod. The bonding spiral ribbon and the rack and pinion spiral ribbon are spiral in shape and fit against the inner wall of the conical drying cylinder, which effectively agitates the internal materials. The comb-like setting of the rack and pinion spiral ribbon also helps to comb the materials and prevent agglomeration.

[0015] As a preferred technical solution of this application, a drive motor is fixedly connected to the top center of the top of the dryer cover via a support rod. The output shaft of the drive motor is downward and coaxially connected to a rotary connector. The rotary connector is coaxially connected to the top of the rotating shaft, thereby effectively realizing the rotation of the rotating shaft. The rotating shaft is fixedly connected to each set of actuating bars.

[0016] Furthermore, when the drive motor starts, it effectively drives the rotating shaft to rotate, thereby rotating the rack and pinion ribbon and the contact ribbon. This agitates the material inside the preliminary drying zone, ensuring it comes into full contact with the primary drying oil chamber, achieving the purpose of preliminary drying. It also agitates the agitator strip below, causing the material located on the upper part of each stage of the progressive material feeding plate to be agitated, ensuring that the material comes into full contact with the corresponding progressive low-temperature drying oil chamber, achieving the purpose of progressive cooling and drying.

[0017] As a preferred technical solution of this application, the top end of the rotating shaft is provided with four sets of L-shaped through holes, which are correspondingly arranged with the rotary connector. The bottom outlet of the L-shaped through holes points from the rotating shaft support arm to the inside of the conical drying cylinder, which facilitates the effective addition of modified substances or other substances during the drying process, thereby effectively realizing the multi-purpose development of the overall dryer.

[0018] As a preferred technical solution of this application, the outer edge of the progressive material feeding plate is uniformly provided with a number of screen holes, which effectively ensures that the dried material falls to the next drying area through the screen holes during the process of moving the material by the bar.

[0019] As a preferred technical solution of this application, the screening plate is divided into six regions, five of which are uniformly provided with screen holes of progressively larger diameter. The guide plate is configured as a fan-shaped ring covering the five regions on the screening plate, and the two ends of the guide plate are provided with abutting screws, thereby effectively adjusting the position of the guide plate and controlling the material in the preliminary drying zone to fall into a specific screen hole area according to the particle size, thereby achieving the purpose of fixed-size screening.

[0020] As a preferred technical solution of this application, the outer side of the conical drying cylinder is provided with a heat insulation layer, which is made of aluminum silicate material. This effectively realizes the heat insulation operation of the primary drying oil chamber and the staged low-temperature drying oil chamber inside the thick wall of the conical drying cylinder, thereby reducing heat loss.

[0021] As a preferred technical solution of this application, a discharge component is provided on one side of the bottom of the insulation layer and the conical drying cylinder, and an oil outlet pipe is provided on the other side of the bottom of the insulation layer and the conical drying cylinder, which is connected to the lowest-level low-temperature drying oil chamber. An oil inlet pipe is provided through the upper outer part of the insulation layer, which is connected to the primary drying oil chamber, thereby facilitating the introduction and export of high-temperature oil for drying. Furthermore, the discharge component effectively controls the export of materials for drying.

[0022] As a preferred technical solution of this application, a feed pipe and a vacuum regulating component are connected to one side of the top of the dryer cover, thereby facilitating the introduction of materials and the exhaust and pressure reduction operations during the drying process.

[0023] As a preferred technical solution of this application, the inner wall of the conical drying cylinder is covered with enamel to further improve the corrosion resistance, and the material of the bonding screw ribbon and the rack screw ribbon is tungsten carbide.

[0024] As a preferred technical solution of this application, the bonding ribbon and the rotating shaft are fixedly connected by multiple sets of connecting rods to achieve stable bonding and rotation of the bonding ribbon. The lowest connecting rod is bonded to the upper part of the guide plate, thereby pushing the material above the guide plate into the designated sieve hole on the screening plate during continuous stirring, thus providing effective preparation for subsequent screening.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. In actual use, the multi-stage drying process of materials is achieved through the combined operation of the preliminary drying zone and the graded low-temperature drying zone. With the setting of the primary drying oil chamber, the partition bar and the graded low-temperature drying oil chamber, the high-temperature oil body used for drying heating is utilized at multiple levels, making full use of resources and achieving drying treatment of materials in multiple temperature ranges. This ensures that the materials are discharged at normal temperature, reduces the phenomenon of moisture absorption and re-dampness after direct high-temperature contact drying, and ensures the drying effect.

[0027] 2. The rack and screw conveyor inside the preliminary drying zone effectively reduces the agglomeration of materials during drying. Combined with the guide plate and screen plate below, the material can be screened according to its particle size, and the particle size can be controlled by screening during the drying process.

[0028] 3. By using the L-shaped through hole on the rotating shaft and the matching rotary connector, the addition of modifying substances can be effectively carried out during the material drying process, thereby achieving material modification and expanding the overall application of the dryer, facilitating multi-purpose development.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Reference Figures 1-7 A multi-purpose corrosion-resistant conical ribbon dryer, comprising:

[0039] The top cover 1 of the dryer is provided with a conical drying cylinder 6 at the bottom. The inner wall of the conical drying cylinder 6 is provided with a primary drying oil chamber 17 and several sets of progressively low-temperature drying oil chambers 19 from top to bottom. A partition strip 18 is provided between the primary drying oil chamber 17 and the progressively low-temperature drying oil chambers 19 and adjacent progressively low-temperature drying oil chambers 19. A connecting oil pump is provided in the partition strip 18 to pump the high-temperature oil in the upper primary drying oil chamber 17 or progressively low-temperature drying oil chamber 19 to the lower progressively low-temperature drying oil chamber 19 for further drying at a lower temperature.

[0040] A sieve plate 14 is provided in the middle of the conical drying cylinder 6. A guide plate 13 is rotatably provided on the upper part of the sieve plate 14. The sieve plate 14 and the guide plate 13 set the upper part of the inner cavity of the conical drying cylinder 6 as a preliminary drying zone, which corresponds to the primary drying oil chamber 17. The lower part of the inner cavity is set as a graded low-temperature drying zone. Several sets of graded discharge plates 15 and agitator bars 16 are provided in the low-temperature drying zone, which correspond to the graded low-temperature drying oil chambers 19 of each grade. They are used to grade and screen the material to ensure that the material is discharged at a lower temperature while drying, thereby reducing the phenomenon of re-moistening caused by high temperature and low humidity of the discharged material.

[0041] A rotating shaft 20 is fixedly installed at the center of the conical drying cylinder 6. The conical drying cylinder 6 is provided with a bonding screw ribbon 12 and a rack screw ribbon 11 in the preliminary drying zone. The bonding screw ribbon 12 and the rack screw ribbon 11 are fixedly connected to the rotating shaft 20 through a connecting rod. The bonding screw ribbon 12 and the rack screw ribbon 11 are spiral and fit against the inner wall of the conical drying cylinder 6, which effectively agitates the internal materials. The comb teeth of the rack screw ribbon 11 are used to comb the materials and prevent clumping.

[0042] The bonding screw 12 is fixedly connected to the rotating shaft 20 by multiple sets of connecting rods to achieve stable bonding and rotation of the bonding screw 12. The lowest connecting rod is bonded to the upper part of the guide plate 13, and then, during the continuous stirring process, the material above the guide plate 13 is pushed into the designated sieve hole on the sieve plate 14, providing effective preparation for subsequent sieving.

[0043] The inner wall of the conical drying cylinder 6 is covered with enamel to further improve its corrosion resistance. The material of the fitting screw ribbon 12 and the rack screw ribbon 11 is tungsten carbide.

[0044] Reference Figures 2-3 The top center of the top cover 1 of the dryer is provided with a drive motor 2 fixedly connected by a support rod. The output shaft of the drive motor 2 is downward and coaxially connected to a rotary connector 4. The rotary connector 4 is coaxially connected to the top of the rotating shaft 20, thereby effectively realizing the rotation of the rotating shaft 20. The rotating shaft 20 is fixedly connected to each set of actuating bars 16.

[0045] When the drive motor 2 starts, it effectively drives the rotating shaft 20 to rotate, thereby rotating the rack and pinion ribbon 11 and the contact ribbon 12. This agitates the material inside the preliminary drying zone, ensuring it comes into full contact with the primary drying oil chamber 17, achieving the purpose of preliminary drying. It also agitates the agitator strip 16 below, causing the material located on the upper part of each stage of the progressive material drop plate 15 to be agitated, ensuring that the material comes into full contact with the corresponding progressive low-temperature drying oil chamber 19, achieving the purpose of progressive cooling and drying.

[0046] Reference Figure 1 , Figure 4 and Figure 7 The top of the rotating shaft 20 is provided with four sets of L-shaped through holes, which are corresponding to the rotary connector 4. The bottom outlet of the L-shaped through holes points from the rotating shaft 20 to the inside of the conical drying cylinder 6. The drive motor 20 drives the rotor of the rotary connector 4 through the coupling, and the rotor drives the rotating shaft 20 to rotate together. The outer shell of the rotary connector 4 is fixed to the frame and remains stationary. The modified material is introduced from the stationary outer shell, and then enters the internal channel of the rotating rotor through the outer shell of the rotary connector 4, and finally reaches the through hole of the shaft, thus forming a always unobstructed transmission channel. This facilitates the effective addition of modified materials or other materials during the drying process, thereby effectively realizing the multi-purpose development of the overall dryer.

[0047] Reference Figure 3 The outer edge of the progressive material feeding plate 15 is evenly provided with several screen holes, which effectively ensures that the dried material falls through the screen holes to the next drying area during the process of the agitator bar 16 moving the material.

[0048] Reference Figure 5 and Figure 6The sieve plate 14 is divided into six areas, five of which are evenly provided with sieve holes of progressively larger diameter. The guide plate 13 is configured to cover the five areas on the sieve plate 14 in a fan-shaped ring, and the two ends of the guide plate 13 are provided with abutting screws, thereby effectively adjusting the position of the guide plate 13 and controlling the material in the preliminary drying zone to fall into a specific sieve hole area according to the particle size, thereby achieving the purpose of fixed-size sieve separation.

[0049] Reference Figures 1-3 The outer side of the conical drying cylinder 6 is provided with a heat insulation layer 7, which is made of aluminum silicate. This effectively achieves the heat insulation of the primary drying oil chamber 17 and the staged low-temperature drying oil chamber 19 within the wall thickness of the conical drying cylinder 6, thereby reducing heat loss.

[0050] A discharge assembly 9 is provided on one side of the bottom end of the insulation layer 7 and the conical drying cylinder 6. An oil outlet pipe 10 is provided on the other side of the bottom end of the insulation layer 7 and the conical drying cylinder 6, which is connected to the lowest stage low temperature drying oil chamber 19. An oil inlet pipe 8 is provided through the upper outer side of the insulation layer 7, which is connected to the primary drying oil chamber 17. This facilitates the introduction and export of high temperature oil for drying. The discharge assembly 9 effectively controls the export of the dried material.

[0051] The top side of the dryer top cover 1 is connected to the feed pipe 5 and the vacuum regulating component 3, which facilitates the introduction of materials and the exhaust and pressure reduction operations during the drying process.

[0052] Workflow: First, the material to be dried is added through the feed pipe 5. Then, high-temperature oil is poured into the primary drying oil chamber 17 through the conical drying cylinder 6 to raise the temperature of the inner wall of the primary drying zone. Then, the drive motor 2 is started, which causes the rotating shaft 20 to drive the rack and pinion ribbon 11, the fitting ribbon 12 and the actuating strip 16 to rotate, pushing and combing the material inside the primary drying zone, preventing clumping and increasing the probability of the material contacting the high-temperature inner wall of the primary drying oil chamber 17, thereby initially improving the drying effect. At the same time, the vacuum regulating component 3 is activated to achieve internal pressure reduction, and the separated water vapor and pressure are discharged to improve the drying effect.

[0053] When the material needs to be screened through the sieve plate 14, before the equipment is dried, the entire equipment is in an open state. The lever is inserted from the top opening of the conical drying cylinder 6 and force is applied to the notch on the guide plate 13 to achieve manual rotation adjustment of the guide plate 13. It is then fixed by the abutting screw on the guide plate 13, thereby exposing the corresponding sieve holes on the sieve plate 14 for subsequent screening.

[0054] After drying to a certain extent, the material passes through the designated sieve holes on the sieve plate 14. At this time, the material is continuously pushed to the sieving area and finally falls into the lower graded low temperature drying zone.

[0055] After the material has undergone preliminary drying, it falls into the graded low-temperature drying zone. At this point, the oil, which has already cooled in the pre-heated jacket of the primary drying oil chamber 17, is pumped through the oil pump inside the separator 18 into the graded low-temperature drying oil chamber 19, achieving drying at a slightly lower temperature. During this process, the rotating shaft 20 drives the actuating strip 16 to move, thus pushing the material and increasing the contact frequency between the material and the inner wall of the graded low-temperature drying oil chamber 19, further improving the drying effect. This also pushes the material, causing it to continuously move to the discharge holes at the edge of the graded discharge plate 15 and fall into the next graded discharge plate. On the material plate 15, the oil chamber 19 corresponding to the next layer of step-by-step material drop plate 15 is pumped by the oil pump inside the partition strip 18 from the high-temperature oil body used in the previous layer. At this time, the high-temperature oil body is further cooled down, and the drying process is achieved at a relatively low temperature in the next layer of step-by-step material drop plate 15. This cycle is repeated, so that the material is dried at a gradually decreasing drying temperature and is finally guided out to effectively present a low temperature state, avoiding excessive temperature difference with the outside air, reducing moisture absorption and re-dampness, and thus achieving the purpose of improving the drying effect.

[0056] During the drying process in the initial drying zone, modified substances can be added through the L-shaped through holes on the rotary connector 4 and the rotating shaft 20, as well as the discharge port, to achieve material modification during the drying process, thereby further expanding the multi-purpose development of the overall dryer.
