Description

Technical Field

[0001] This utility model belongs to the field of drying technology, specifically relating to an internally insulated high-temperature resistant dryer. Background Technology

[0002] Specialized dryers are required for drying and dehydrating coal slime and materials with high moisture content and high viscosity in the coal industry. These devices utilize high-temperature heat sources to evaporate moisture from materials through heat conduction and convection. They are designed with stirring and crushing structures tailored to the characteristics of the materials to prevent sticking and clumping, efficiently reducing moisture content to acceptable levels. This facilitates the resource utilization, transportation, and storage of materials, making them key equipment for improving quality and efficiency in related industries.

[0003] For example, a coal slime filter cake forming dryer is disclosed in related technology (Chinese patent with announcement number CN2700792Y). The through-flow mesh plate assembly of this machine has a transmission chain structure composed of a U-shaped ring and a three-ring chain. The long shaft of the mesh plate device is connected to the transmission chain through a transmission sleeve fixed to the U-shaped ring. Baffles are installed on both sides of the mesh plate. The two extrusion rollers of the double-roll forming machine have grooves on their surfaces, arranged in an alternating pattern. The scraper device is mounted on a fixed bracket via a hinged screw connection. The scraper blade structure is opposite to that of the two main and secondary extrusion rollers, with the two forming a concave-convex contact. The outer shell of the machine is constructed from multiple cover plates, with an aluminum silicate blanket insulation layer inside. This machine operates stably, has low maintenance and failure rate, high throughput, and high efficiency.

[0004] In the current market, high-moisture, high-viscosity materials and large quantities of coal slime from coal washing plants in the coal industry all require high-temperature hot air drying to meet production demands. However, most dryers on the market currently employ an external insulation design, meaning the insulation layer is located on the outside of the dryer, while the inner side, consisting of a steel structure, directly contacts the material being dried. This causes the material to easily stick to the walls after the high-temperature hot air enters the dryer, potentially leading to carbonization and ignition, and causing deformation of the dryer's steel structure. This not only shortens the equipment's lifespan but also increases maintenance workload. Utility Model Content

[0005] To address the problems of existing dryers, which are mostly designed with external insulation and where the inner steel structure directly contacts the material, leading to material sticking to the walls, carbonization, and ignition upon the introduction of high-temperature hot air, causing steel structure deformation, shortening equipment lifespan, and increasing maintenance, this invention provides an internally insulated high-temperature resistant dryer. The internal insulation layer prevents direct contact between high-temperature materials and the steel structure frame, thus avoiding carbonization, ignition, and deformation problems caused by direct contact. This structural improvement not only ensures stable operation of the dryer during its normal service life, significantly reducing maintenance workload and costs, but also, by preventing material sticking to the walls and carbonization from interfering with the drying process, allows for more thorough heat exchange between the material and the high-temperature hot air, improving drying efficiency and maximizing the amount of material dried. Simultaneously, it extends the equipment's service life and provides a reliable guarantee for continuous and efficient production. The specific technical solution is as follows: A high-temperature resistant dryer with internal insulation includes a base, and further includes: a dryer body, a dryer protective layer, an inner insulation layer, a steel frame, and an exhaust fan assembly.

The air inlet is connected to an external high-temperature hot air furnace. The air outlet is located on the upper right side of the dryer protective layer and penetrates downward through the dryer protective layer and the inner insulation layer. The air outlet is connected to an external exhaust fan.

[0007] In the above technical solution, a crossbeam assembly is provided inside the inner insulation layer. The crossbeam assembly includes a wind baffle and a lintel.

The lintel is installed at the bottom end of the wind baffle. The wind deflector is made of a high-temperature resistant non-metallic material, and the crossbeam is made of a high-temperature resistant and wear-resistant metallic material.

[0008] The above technical solution also includes a partition assembly, which includes a positioning bolt and a first partition. The positioning bolt passes through the side wall of the lintel in a horizontal direction. The first partition is installed on the left side of the lintel, and the positioning bolt passes through the side wall of the first partition. The positioning bolt is connected between the lintel and the first partition.

[0009] The above technical solution also includes: a second partition, which is provided in two sets, with the two sets of the second partition respectively arranged in the inner cavity of the inner insulation layer along the front-back direction, and the two sets of the second partition arranged in parallel. The second partition is located on the right side of the first partition.

[0010] In the above technical solution, a dryer protective layer is provided on the right side of the bottom of the dryer body, and the left side wall of the dryer protective layer is inclined from top to bottom in a downward trend.

[0011] In the above technical solution, an explosion-proof opening is provided above the dryer protective layer, and the explosion-proof opening penetrates the dryer protective layer and the inner insulation layer in a vertical direction.

[0012] In the above technical solution, the front and rear side walls of the dryer protective layer are respectively provided with observation doors that can be rotated and opened.

[0013] In the above technical solution, a feed inlet is provided on the left side of the dryer body.

[0014] The above technical solution also includes: a motor, a rotating shaft, and lifting plates. The motor is mounted on the base via a motor frame. One end of the rotating shaft is connected to the output end of the motor, and the other end extends into the inner cavity of the dryer body. A plurality of lifting plates are provided, and the plurality of lifting plates are arranged circumferentially along the outer wall of the rotating shaft. The lifting plates are arranged in alternating layers on the side wall of the rotating shaft.

[0015] The advantages of this internally insulated high-temperature dryer compared to existing technologies are as follows: I. Addressing the problem that most existing dryers feature external insulation with the inner steel structure directly contacting the material, leading to material sticking to the walls, carbonization, and ignition upon the introduction of high-temperature hot air, causing steel structure deformation, shortening equipment lifespan, and increasing maintenance, this invention provides an internal insulation layer on the inner wall of the dryer and places the steel frame on the outside. A protective layer is placed between the internal insulation layer and the outer steel frame, forming the overall dryer body. In this invention, the internal insulation layer prevents high-temperature materials from directly contacting the material. The problem of carbonization, fire, or deformation caused by direct contact with the steel structure frame is fundamentally avoided. This structural improvement not only ensures the stable operation of the dryer during its normal service life and significantly reduces maintenance workload and costs, but also prevents material from sticking to the wall and carbonization from interfering with the drying process. This allows the material to exchange heat more fully with the high-temperature hot air, improving drying efficiency and maximizing the amount of material dried. At the same time, it extends the service life of the equipment and provides a reliable guarantee for continuous and efficient production. Second, the dryer protective layer, as an intermediate medium connecting the inner insulation layer and the steel structure frame, can, on the one hand, play an auxiliary role in heat preservation of the dryer cavity temperature and reduce heat loss to the external environment; on the other hand, it can block the high temperature inside the dryer from being directly conducted to the steel structure frame, thereby achieving heat insulation protection for the steel structure frame and preventing the steel structure frame from deteriorating in performance or structural damage due to long-term exposure to high temperatures. Third, by configuring functional components such as a motor, rotating shaft, and lifting plates, this utility model can achieve a full and repeated lifting effect on the material inside the dryer cavity. This structure enables the material to have all-round and high-frequency contact with the high-temperature air inside the cavity, enhancing heat exchange efficiency and accelerating moisture evaporation. At the same time, in conjunction with the high-temperature air environment, it can effectively lift and break up materials with high water content and high viscosity, solving the problem of easy agglomeration and clumping of such materials, and ensuring that all material particles are fully exposed to the drying medium. This method not only ensures the uniform drying effect of the material inside the dryer cavity and avoids local excessive humidity or substandard drying, but also increases the specific surface area of ​​the material through the crushing and dispersing effect, further improving the drying rate. Ultimately, the discharged finished material fully meets the preset drying indicators, significantly improving the drying quality and efficiency of high-difficulty materials, and providing a stable and qualified raw material foundation for subsequent processing. Fourth, in this utility model, the lifting plates installed on the rotating shaft are distributed circumferentially along the side wall of the rotating shaft in a stacked and staggered manner. This distribution method ensures that the material is lifted, and the material can be thrown up in an irregular state by the staggered lifting plates, thereby avoiding the problem of limited lifting effect caused by the regular and neat arrangement of the lifting plates. At the same time, it can further break the original movement path and trajectory of the material, so that the material can come into fuller contact with the high temperature air, thereby improving the drying effect. In summary, this utility model, through its integrated structure consisting of an inner insulation layer, a dryer protective layer, and a steel frame, fundamentally avoids the carbonization, ignition, and deformation problems caused by direct contact between high-temperature materials and the steel frame. This ensures stable equipment operation, significantly reduces maintenance workload and costs, while simultaneously improving drying efficiency, maximizing material drying capacity, extending equipment lifespan, and providing a reliable guarantee for continuous and efficient production. The dryer protective layer, as an intermediate medium, not only assists in heat preservation to reduce heat loss but also blocks direct conduction of high temperatures to the steel frame, achieving thermal insulation and preventing performance degradation or structural damage to the steel frame. The motor, shaft, and lifting plates... By repeatedly lifting the material, these components ensure it comes into full, high-frequency contact with high-temperature air, enhancing heat exchange and accelerating moisture evaporation. They also break up high-moisture, high-viscosity materials to overcome agglomeration and clumping, ensuring uniform drying, preventing localized substandard drying, increasing the drying rate, and making the finished product meet preset specifications. This significantly improves the quality and efficiency of drying difficult materials, providing stable and qualified raw materials for subsequent processing. The lifting plates are arranged in a staggered, layered pattern on the circumference of the rotating shaft sidewall. They can both lift the material and throw it irregularly, avoiding the limitations of a regularly set lifting effect, breaking the material's movement trajectory, and allowing the material to come into fuller contact with high-temperature air, thus improving the drying effect.

Detailed Implementation

[0017] The following are specific implementation cases and appendices. Figures 1 to 4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0018] A high-temperature resistant dryer with internal insulation includes a base 1, and further includes: a dryer body 2, a dryer protective layer 3, an inner insulation layer 4, a steel frame 5, and an exhaust fan assembly. The dryer body 2 is mounted on the base 1; the dryer protective layer 3 is mounted on the dryer body 2, forming a dryer together with the dryer body 2, and the top of the dryer protective layer 3 is configured as a dome structure; the inner insulation layer 4 is located inside the dryer protective layer 3; the steel frame 5 is located outside the dryer protective layer 3; and the exhaust fan assembly is located above the dryer protective layer 3. The inner insulation layer 4 is made of a high-temperature resistant non-metallic material, and is installed in the dryer cavity through masonry or pouring processes on the inner wall and dome of the dryer; an expansion space is reserved between the inner insulation layer 4 and the steel frame 5, and the expansion space is filled with material to form the dryer protective layer 3.

[0019] This invention designs the dryer with a three-layer composite structure: an inner insulation layer 4 on the inner side, a steel frame 5 on the outer side, and a dryer protective layer 3 between the two. The inner insulation layer 4, the dryer protective layer 3, and the steel frame 5 together form the overall body of the dryer. This structure, through the isolation effect of the inner insulation layer 4, fundamentally prevents direct contact between high-temperature materials and the steel frame 5, completely solving the problems of carbonization and fire, as well as deformation of the steel frame 5. This not only ensures stable operation of the dryer throughout its entire lifespan, significantly reducing maintenance frequency and costs, but also avoids material sticking to the walls and carbonization interfering with the drying process, allowing for more thorough heat exchange between the material and the high-temperature hot air. This effectively improves drying efficiency and throughput, while extending the equipment's service life and providing a solid guarantee for continuous and efficient production. The dryer protective layer 3 serves as the connecting medium between the inner insulation layer 4 and the steel structure frame 5, and has a dual function: on the one hand, it can help maintain the temperature inside the dryer cavity, reduce heat loss to the outside, and enhance the insulation effect; on the other hand, it can prevent the high temperature inside the machine from being directly transferred to the steel structure frame 5, thereby achieving heat insulation protection for the steel structure frame 5 and preventing it from experiencing performance degradation or structural damage due to long-term exposure to high temperatures.

[0020] Specifically, the air extraction assembly includes an air inlet 6 and an air outlet 7. The air inlet 6 is located on the upper left side of the dryer protective layer 3, and extends downwards through the dryer protective layer 3 and the inner insulation layer 4. The air inlet 6 is connected to an external high-temperature hot air furnace. The air outlet 7 is located on the upper right side of the dryer protective layer 3, and extends downwards through the dryer protective layer 3 and the inner insulation layer 4. The air outlet 7 is connected to an external exhaust fan. This equipment uses existing commercially available mature models of high-temperature hot air furnaces and exhaust fans. The high-temperature hot air furnace provides the equipment with high-temperature hot air sufficient for material drying through the air inlet 6. The exhaust fan, located at the air outlet 7, extracts the dried air for subsequent processing steps. This is existing technology, and the model and other parameters of the high-temperature hot air furnace and exhaust fan are not limited or described here; both are sufficient to meet the usage requirements.

[0021] The inner insulation layer 4 is equipped with a crossbeam assembly, which includes a wind baffle 8 and a lintel 9. Two sets of wind baffles 8 are installed in parallel along the front-to-back direction within the inner cavity of the inner insulation layer 4. The lintel 9 is installed at the bottom of the wind baffles 8. The wind baffles 8 are made of a high-temperature resistant non-metallic material. The lintel 9 is made of a high-temperature resistant and wear-resistant metallic material. Because the coal slime drying environment needs to withstand temperatures of 200-800℃, and the material has a certain degree of abrasiveness, the lintel 9 is made of high-chromium cast iron or a nickel-based high-temperature alloy. High-chromium cast iron contains 12%-30% chromium, which not only forms a dense oxide film at high temperatures and can withstand temperatures of around 800℃, but also has excellent wear resistance, resisting the erosion and wear of coal slime particles and adapting to the material contact conditions during coal slime drying. Nickel-based high-temperature alloys can maintain stable mechanical properties in high-temperature environments above 1000℃, have strong oxidation and corrosion resistance, can cope with the complex media environment that may occur during coal slime drying, and also have a certain degree of wear resistance, ensuring that the lintel 9 can operate reliably under long-term high temperature and material friction conditions.

[0022] The guide beam 9 installed inside the dryer can guide the movement path of the material inside the machine, realize the regional processing of the material, and improve the uniformity of drying. Moreover, the high temperature resistance of the guide beam 9 itself can ensure that it will not be damaged by overheating when it comes into contact with the material under high temperature hot air conditions. It plays a role in strengthening the overall structural stability of the dryer, effectively suppressing excessive deformation of the equipment caused by thermal expansion and contraction, and ensuring continuous and stable operation of the equipment.

[0023] The inner insulation layer 4 and the wind baffle 8 are made of high-temperature resistant non-metallic materials. Specifically, both use refractory castables that meet the above requirements, such as aluminate refractory castables or silicon carbide refractory bricks. The drying temperature of coal slime is usually between 200-800℃. The refractoriness of aluminate refractory castables can reach 1500-1700℃, and the refractoriness of silicon carbide refractory bricks is as high as 1600-1800℃, both of which can withstand the high-temperature environment during the coal slime drying process. At the same time, these materials have good thermal shock resistance and wear resistance, can adapt to the temperature fluctuations and material scouring conditions inside the dryer, and have strong chemical stability, will not react with the components in the coal slime, and are suitable for coal slime drying scenarios.

[0024] This solution also includes a partition assembly, which includes a positioning bolt 11 and a first partition 10. The positioning bolt 11 passes through the side wall of the lintel 9 in a horizontal direction. The first partition 10 is installed on the left side of the lintel 9, and the positioning bolt 11 passes through the side wall of the first partition 10. The positioning bolt 11 connects the lintel 9 and the first partition 10, and the positioning bolt 11 forms a connection between the first partition 10 and the lintel 9, so that both can play their respective roles while increasing the connection and stability between them.

[0025] This solution also includes: a second partition 12, of which two sets of second partition 12 are provided. The two sets of second partition 12 are respectively arranged in the inner cavity of the inner insulation layer 4 along the front-back direction, and the two sets of second partition 12 are arranged in parallel. The second partition 12 is located to the right of the first partition 10. During the drying process, after the high temperature air and the high moisture material come into full contact and complete the drying process, the air flows under the guidance of the channel formed by the alternating partitions of the second partition 12 and the first partition 10, and finally the dried material is discharged from the inner cavity of the dryer through the discharge port 13.

[0026] A dryer protective layer 3 is located on the bottom right side of the dryer body 2. The left side wall of the dryer protective layer 3 slopes downwards from top to bottom, ensuring that the dried material can be smoothly discharged from the dryer cavity along the inclined inner wall of the dryer protective layer 3. An explosion-proof vent 14 is located above the dryer protective layer 3, penetrating vertically through the dryer protective layer 3 and the inner insulation layer 4. The explosion-proof vent 14 facilitates manual maintenance and inspection of the dryer cavity. Rotatable and transparent observation doors 15 are located on the front and rear side walls of the dryer protective layer 3, allowing observation of the drying process within the dryer cavity.

[0027] A feed inlet 16 is provided on the left side of the dryer body 2, through which the material to be dried can be fed into the inner cavity of the dryer body 2 for subsequent drying. This solution also includes: a motor 17, a rotating shaft 18, and lifting plates 19. The motor 17 is mounted on the base 1 via a motor frame; one end of the rotating shaft 18 is connected to the output end of the motor 17, and the other end extends into the inner cavity of the dryer body 2; several lifting plates 19 are provided, and the lifting plates 19 are arranged circumferentially along the outer wall of the rotating shaft 18; the motor 17 adopts a commercially available self-locking motor with a lockable output end. When it stops, the output end can be self-locked and will not rotate under external force, and its output end is connected to a reducer. Through the cooperation of the motor 17 and the reducer, the rotating shaft 18 and the lifting plates 19 can be driven to rotate circumferentially. The motor 17 is a commercially available mature component that can meet the above-mentioned usage requirements, and will not be described or limited here; the lifting plates 19 are arranged in a staggered layer on the side wall of the rotating shaft 18.

[0028] In this invention, the lifting plates 19 are installed circumferentially along the side wall of the rotating shaft 18 in a stacked, staggered manner. This distribution method ensures the lifting function of the material while allowing the material to be thrown up irregularly by the staggered lifting plates 19, thus solving the problem of limited lifting effect when the lifting plates 19 are arranged in a regular and orderly manner. At the same time, it can further break the original movement path and trajectory of the material, allowing the material to have more sufficient contact with the high-temperature air, thereby improving the drying effect.

[0029] This invention is equipped with functional components such as a motor 17, a rotating shaft 18, and a lifting plate 19, which can fully and repeatedly lift the material inside the dryer cavity. This structure can promote all-round, high-frequency contact between the material and the high-temperature air inside the cavity, enhancing heat exchange efficiency and accelerating moisture evaporation. At the same time, combined with the high-temperature air environment, it can effectively lift and break up high-moisture, high-viscosity materials, solving the problem of easy agglomeration and ensuring that all material particles are fully exposed to the drying medium. This method not only ensures uniform drying of materials inside the dryer cavity, avoiding localized excessive humidity or substandard drying, but also increases the specific surface area of ​​the material through crushing and dispersion, further improving the drying rate. Ultimately, the discharged finished material fully meets the preset drying indicators, significantly improving the quality and efficiency of drying difficult materials and providing stable and qualified raw materials for subsequent processing stages.

[0030] The working principle of the internal insulation type high-temperature resistant dryer in this embodiment is as follows: The material to be dried is fed into the inner cavity of the dryer body 2 through the feed inlet 16. The motor 17, which is in the open state, drives the rotating shaft 18 and the lifting plate 19 to rotate circumferentially, so that the lifting plate 19 lifts the material, allowing the material to fully contact the high-temperature air entering through the feed inlet 16 to complete the drying process. During the drying process, after the high-temperature air and the high-moisture material have fully contacted and completed the drying process, the air flows under the guidance of the channel formed by the alternating partitions of the second partition 12 and the first partition 10, and finally the dried material is discharged from the inner cavity of the dryer through the discharge outlet 13. In the above-mentioned overall drying process, the inner insulation layer 4 plays a protective role for the inner cavity of the dryer, which can prevent the deformation caused by the direct action of high temperature air on the steel structure frame 5, and at the same time ensure that the dryer maintains a normal drying operation. In this utility model, the overall machine structure, consisting of an inner insulation layer 4, a dryer protective layer 3, and a steel frame 5, fundamentally avoids the carbonization, ignition, and deformation problems caused by direct contact between high-temperature materials and the steel frame 5. This ensures stable equipment operation, significantly reduces maintenance workload and costs, while improving drying efficiency, maximizing material drying capacity, extending equipment lifespan, and providing a reliable guarantee for continuous and efficient production. The dryer protective layer 3, as an intermediate medium, not only assists in heat preservation to reduce heat loss but also blocks the direct conduction of high temperature to the steel frame 5, achieving thermal insulation protection and preventing performance degradation or structural damage to the steel frame 5. The motor 17, rotating shaft 18, and material lifting mechanism are also included. The lifting plates 19 and other components repeatedly and thoroughly lift the material, enabling it to come into full-range, high-frequency contact with high-temperature air. This enhances heat exchange and accelerates moisture evaporation. It also breaks up high-moisture, high-viscosity materials to overcome agglomeration and clumping problems, ensuring uniform drying, preventing localized substandard drying, increasing the drying rate, and ensuring the finished product meets preset specifications. This significantly improves the quality and efficiency of drying difficult materials, providing stable and qualified raw materials for subsequent processing. The lifting plates 19 are distributed in a staggered, layered manner along the circumference of the side wall of the rotating shaft 18. They can both lift the material and throw it irregularly, avoiding the limitations of a regularly set lifting effect, breaking the material's movement trajectory, and allowing the material to come into more full contact with high-temperature air, thus improving the drying effect.
