Description

Technical Field

[0001] This utility model relates to the technical field of chemical equipment, specifically to an SA reaction drying and purification system. Background Technology

[0002] In the SA reaction production process, the post-processing of the finished product is crucial. Drying, as the final quality optimization step, directly determines the quality grade of the SA product, the company's production efficiency, and the utilization efficiency of energy resources through its process level and heating method. Currently, most SA production companies have not yet equipped themselves with professional drying and purification systems, leading to frequent problems such as insufficient material drying and impurity residue, seriously affecting the quality stability and purity of the finished SA product. The few companies that have introduced drying equipment still generally use the traditional method of electric heating.

[0003] Electric heating typically converts electrical energy into heat energy through heating elements such as resistance wires, which is then transferred to the material. Although this method heats up quickly, it suffers from uneven heating. During the drying process, materials near the heating element are prone to deterioration and carbonization due to localized overheating, while materials far from the heating element may not dry sufficiently. Utility Model Content

[0004] The present invention aims to provide an SA reaction drying and purification system to solve the technical problem that the SA reaction materials cannot meet the high-quality drying requirements due to uneven heating caused by traditional electric heating.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: 1) An SA reaction drying and purification system includes a workbench, on the upper surface of which is provided a first support and a second support. An inclined heating device is mounted on the upper part of the first support and the second support. The heating device includes an inner cylinder wall and an outer cylinder wall, and a sealed chamber is formed between the inner cylinder wall and the outer cylinder wall. A steam pipe is axially wound in the chamber. The steam pipe in the chamber has a number of steam holes evenly distributed. A roller protruding from the inner cylinder wall passes through the inner cylinder wall along its central axis. The roller and the inner cylinder wall are rotatably connected. The roller has an inlet and an outlet at both ends. A drive mechanism for driving the roller to rotate is provided at the end of the roller.

[0006] In this utility model, the workbench serves as the basic load-bearing structure. A first support seat and a second support seat are provided on the upper surface of the workbench. The first support seat and the second support seat are used to tilt and support the heating device. The heating device includes an inner cylinder and an outer cylinder that are coaxially sleeved together. A sealed chamber is formed between the inner cylinder and the outer cylinder. A steam pipe is arranged axially around the chamber. The steam pipe has evenly distributed steam holes that can release steam evenly into the chamber, thereby heating the material inside the drum.

[0007] A roller is installed through the inner cylinder wall along the central axis. The roller can rotate inside the inner cylinder wall. A feed port and a discharge port are respectively set at both ends of the roller. The feed port is used for material input, and the discharge port is used for material output. A drive mechanism is set at the end of the roller near the feed port. The drive mechanism provides power for the rotation of the roller, ensuring that the material continuously tumbles inside the roller.

[0008] The tilting of the heating device, combined with the rotation of the drum, allows the material to tumble fully inside the drum, making full use of the heat released by the steam, ensuring uniform heating of the material, and improving the drying effect. The sealed chamber structure effectively reduces heat loss and improves heat utilization. The steam pipes are arranged around the drum and the steam holes are evenly distributed to ensure uniform steam release, further ensuring the uniformity of heating. The steam recycling design reduces energy consumption and lowers the drying cost of the material.

[0009] 2) According to the SA reaction drying and purification system described in 1), wherein: The height of the first support is greater than the height of the second support. The first and second support are respectively supported on both sides of the outer cylinder wall. The upper surfaces of the first and second support are arc surfaces that fit the outer surface of the outer cylinder wall. Several flanges are fixedly connected to both sides of the outer cylinder wall along its circumferential direction. The arc surfaces of the first and second support are respectively provided with slots corresponding to several flanges, and the flanges are embedded in the slots.

[0010] In this invention, the height of the first support seat is greater than the height of the second support seat. Both support seats are respectively supported at both ends of the outer cylinder wall. The upper surfaces of both the first and second support seats are arc surfaces adapted to the outer surface of the outer cylinder wall. This design allows the first and second support seats to fit tightly against the outer cylinder wall, providing stable support for the outer cylinder wall. Several flanges are provided at both ends of the outer cylinder wall along the circumferential direction. Correspondingly, the arc surfaces of the first and second support seats are respectively provided with grooves corresponding to the flanges. The flanges can be accurately embedded in the grooves. This matching method can effectively limit the axial movement of the outer cylinder wall and ensure that the outer cylinder wall remains stable during operation.

[0011] In this invention, the heating device remains stable during operation, preventing uneven heat transfer due to shaking or displacement, and ensuring the stability of the heating effect. The cooperation between the flange and the slot enhances the overall structural strength of this invention, reduces component wear caused by vibration, lowers the probability of failure, extends the service life of the equipment, and ensures long-term stable operation of the equipment.

[0012] 3) According to the SA reaction drying and purification system described in 1), wherein: The drive mechanism includes a ring-shaped gear ring that is fitted around the outside of the inner cylinder wall of the drum. Several connecting blocks are evenly distributed around the drum and are located between the drum and the gear ring. The lower surface of the connecting blocks is fully welded to the outer surface of the drum, and the upper surface of the connecting blocks is fully welded to the inner ring of the gear ring. The gear ring meshes with gears, and the gears are connected to a servo motor for driving the gears to rotate. The servo motor is fixedly connected to the worktable.

[0013] In this invention, the driving mechanism includes a gear ring, a gear, and a servo motor. The gear ring has an annular structure and is fitted around the outside of the inner cylinder wall of the roller. Several connecting blocks are evenly distributed around the circumference of the roller. The connecting blocks are located between the roller and the gear ring. The lower surface of the connecting block is fully welded to the outer surface of the roller, and the upper surface of the connecting block is fully welded to the inner ring of the gear ring. This connection method can ensure that the gear ring and the roller rotate synchronously. The gear ring meshes with the gear, and the gear is connected to the servo motor. The servo motor acts as a power source, driving the gear to rotate, thereby driving the gear ring and the roller to rotate.

[0014] The fully welded connection between the connecting block and the roller, as well as between the connecting block and the gear ring, ensures the robustness and stability of the connection between the gear ring and the roller. It is not easy to loosen even when the roller rotates at high speed or is under heavy load, thus ensuring the reliability of power transmission. The meshing transmission between the gear ring and the gear ensures the stability of the roller speed, keeps the material movement within the roller consistent, and improves the material handling efficiency.

[0015] 4) An SA reaction drying and purification system according to 1), wherein: The drum contains several sets of lifting plates, each set including several first lifting plates and several second lifting plates. The first lifting plates are arranged circumferentially inside the drum, and each second lifting plate is located between two adjacent first lifting plates.

[0016] In this invention, when the drum rotates, the first lifting plate can lift the material to a certain height, and then the material falls onto the second lifting plate under the action of gravity. The second lifting plate can prolong the time of material falling, so that the material can be more fully dispersed inside the drum, and the drying effect of the material from the inside to the outside is better.

[0017] 5) An SA reaction drying and purification system according to 1), wherein: It also includes a steam generator, which is fixed to the workbench with bolts and nuts. The lower part of the chamber near the discharge port is provided with a water outlet pipe. The steam generator is provided with a water inlet and a steam outlet. The water inlet is connected to a water inlet pipe, which is connected to the chamber through the water outlet pipe. The steam outlet is connected to a steam pipe. A drain valve is installed on the water outlet pipe, and a water pump is installed on the water inlet pipe.

[0018] The steam generator is equipped with a water inlet and a steam outlet. The steam outlet is connected to a steam pipe. The steam generated by the steam generator enters the steam pipe, which is used to transport the steam into the chamber and then release it into the chamber through the steam hole to heat the material. After the steam releases heat, it condenses into liquid water. Since the heating device is set at an incline, the condensate will flow to the bottom of the chamber and gradually accumulate at the bottom end along the incline of the chamber.

[0019] A water inlet pipe is connected to the water inlet, and a water pump is installed on the water inlet pipe. The water outlet pipe is located at the bottom of the chamber along the inclined direction and is connected to the chamber. A steam trap is installed on the water outlet pipe. The steam trap only allows condensate to be discharged through the water outlet pipe, while preventing steam leakage. After the condensate enters the water outlet pipe through the steam trap, it is transported back to the water inlet pipe of the steam generator under the drive of the water pump. Finally, it is reheated into steam by the steam generator and enters the steam pipe. This utility model not only ensures that the chamber is always filled with efficiently heated steam, but also realizes the recycling of water resources.

[0020] 6) An SA reaction drying and purification system according to 1), wherein: Two rings of rollers are evenly arranged along the axial direction on the outer surface of the drum. Each ring of rollers includes several rollers evenly distributed along the circumferential direction of the drum. The rollers are rotatably connected to a rotating shaft, and the two ends of the rotating shaft are fixedly connected to two support rods set on the drum. The inner wall surface of the drum has an annular groove. The position of the annular groove corresponds to the position of the roller group. All rollers in the roller group are inserted into the annular groove and roll along the annular groove.

[0021] In this invention, two concentric roller sets are evenly arranged along the axial direction on the outer surface of the drum. Each concentric roller set includes several rollers evenly distributed along the circumferential direction of the drum. A rotating shaft passes through each roller, and the two ends of the rotating shaft are respectively connected to two support rods set on the drum, so that the roller can rotate freely. The inner wall surface of the drum is provided with an annular groove, the position of which corresponds to the position of the roller set. All rollers in the roller set are inserted into the annular groove and can slide along the annular groove.

[0022] The combination of the roller assembly and the annular groove provides a stable support structure for the drum, ensuring that the drum will not deviate or wobble during rotation, making the movement trajectory of the material inside the drum more stable and conducive to uniform drying of the material; the rollers are connected to the drum through bearings, which reduces the frictional resistance between the rollers and the drum, reduces energy loss, and improves the operating efficiency of the equipment.

[0023] The design of the roller and the annular groove allows the roller to rotate stably within the inner cylinder wall. At the same time, the cooperation between the roller and the annular groove restricts the radial movement of the roller, reduces shaking during rotation, helps extend the service life of the roller and related components, and reduces maintenance costs.

[0024] 7) An SA reaction drying and purification system according to 1), wherein: The roller has a sealing cover inside the feed inlet with a feed hole. A feed pipe and a blower are installed on the worktable. The feed pipe extends into the feed hole, and the blower is used to ventilate the roller through the feed hole.

[0025] In this invention, a sealing cover is provided inside the feed inlet of the roller, and a feed hole is provided on the sealing cover. The feed pipe extends into the feed hole and can guide the material smoothly into the roller, preventing the material from spilling.

[0026] A blower is installed on the workbench, which blows air into the drum to promote the flow and mixing of materials and improve the drying effect. The sealing cover prevents material leakage and ensures a clean and safe working environment. The design of the feed pipe allows materials to enter the drum smoothly, reducing the possibility of material accumulation and blockage, and improving the efficiency and stability of feeding.

[0027] 8) An SA reaction drying and purification system according to 7), wherein: An air inlet pipe is connected to the feed pipe. An air inlet ring is fixedly connected to one end of the feed pipe that extends into the feed hole. A first branch pipe is connected between the feed pipe and the air inlet ring. A second branch pipe is connected to the air inlet ring. The first branch pipe is connected to the second branch pipe. Air outlet holes are evenly distributed in the direction of the air inlet ring towards the inside of the drum. The air inlet ring is located on the inner side of the sealing cover facing the inside of the drum. There are gaps between the air inlet ring, the sealing cover, and the drum. The air inlet pipe is connected to the blower.

[0028] In this invention, material is fed into the drum through the feed pipe. The blower is then started, and ventilation is provided through the air inlet pipe into the feed pipe. The air carries the material into the drum, accelerating its flow and allowing it to be scattered throughout the drum, preventing accumulation. The airflow also enters the first branch pipe, then the second branch pipe, and finally the air inlet ring through both the first and second branch pipes. Finally, it enters the drum through the air outlet. Both the air inlet ring and the feed pipe ventilate the drum, ensuring a uniform airflow and creating an airflow from the feed inlet to the discharge outlet. This airflow carries away the moisture from the dried material, accelerating the drying process.

[0029] Compared with the prior art, this utility model also has the following technical effects: This utility model uses coaxially fitted inner and outer cylinder walls to form a sealed chamber. The sealed chamber is the basis for achieving efficient heating and effectively prevents heat from spreading to the outside. Compared with the open structure, the heat utilization rate is greatly improved. The steam pipe is designed to wrap around the axial direction, so that the material can obtain uniform heating conditions no matter where it is in the drum during the rotation process, avoiding local overheating or undercooling.

[0030] The uniform distribution of steam holes ensures that steam can be released into the chamber at a stable flow rate and pressure, maintaining the stability of the heating environment. In the steam circulation system, the steam trap discharges condensate to ensure the purity of the steam in the chamber and prevent the heating efficiency from being affected by moisture accumulation. After the condensate enters the outlet pipe through the steam trap, it is transported back to the inlet of the steam generator by the water pump and is finally reheated into steam by the steam generator and enters the steam pipe, realizing the recycling of water resources and reducing the cost of material drying.

[0031] Secondly, a drive mechanism is installed at the end of the drum, including a gear ring, gears, and a servo motor. The gear ring is welded to the drum via a connecting block, which, compared to bolt and nut connections, can withstand greater torque and is less prone to loosening under long-term, high-intensity operation, ensuring stable power transmission. The fit between the roller assembly and the annular groove reduces vibration and offset, lowers equipment wear, and extends the equipment's service life. The feed pipe at the inlet guides the material smoothly into the drum, preventing accumulation. The blower blows air into the drum, promoting material dispersion and accelerating airflow to assist in material drying and improve drying efficiency. Attached Figure Description

[0033] The following detailed description illustrates the specific implementation methods: The reference numerals in the accompanying drawings include: workbench 1, first support base 2, second support base 3, outer cylinder wall 4, inner cylinder wall 5, chamber 6, feed pipe 7, steam pipe 8, gear ring 9, connecting block 10, gear 11, servo motor 12, roller 13, annular groove 14, roller 15, sealing cover 16, air inlet pipe 17, air inlet ring 18, first branch pipe 19, water outlet pipe 20, second branch pipe 21, mounting bracket 22, exhaust fan 23, flange 33, slot 34, first lifting plate 35, second lifting plate 36.

[0034] See the example. Figure 1As shown, this embodiment is an SA reaction drying and purification system, including a workbench 1. A first support base 2 and a second support base 3 are welded on the workbench 1. The top of the first support base 2 is higher than the top of the second support base 3. A heating device is mounted on the upper part of the first support base 2 and the second support base 3 in an inclined manner. The heating device includes an inner cylinder wall 5 and an outer cylinder wall 4 coaxially sleeved. A sealed chamber 6 is formed between the inner cylinder wall 5 and the outer cylinder wall 4. A steam pipe 8 is axially wound in the chamber 6. The steam pipe 8 located in the chamber 6 has a number of steam holes evenly distributed. A roller 13 protruding from the inner cylinder wall 5 is inserted along its central axis. The roller 13 can rotate in the inner cylinder wall 5. The roller 13 has an inlet and an outlet at both ends. A drive mechanism for driving the roller 13 to rotate is provided at the end of the roller 13.

[0035] In this embodiment, the workbench 1 serves as the basic load-bearing structure. The upper surface of the workbench 1 is provided with a first support seat 2 and a second support seat 3 of different heights. The first support seat 2 and the second support seat 3 of different heights are used to tilt the heating device, so that the material in the drum 13 can flow naturally under the action of gravity, which helps the material to be transported and mixed. The heating device is composed of an inner cylinder wall 5 and an outer cylinder wall 4 coaxially fitted together. A sealed chamber 6 is formed between the inner cylinder wall 5 and the outer cylinder wall 4. A steam pipe 8 filled with steam is arranged axially around the chamber 6. The steam holes evenly distributed on the steam pipe 8 can release steam evenly into the chamber 6, thereby heating the material in the drum 13.

[0036] A roller 13 is installed through the inner cylinder wall 5 along the central axis. The roller 13 can rotate inside the inner cylinder wall 5. The roller 13 has a feed port and a discharge port at both ends. The feed port is used for material input and the discharge port is used for material output. A drive mechanism is provided at the end of the roller 13 near the feed port. The drive mechanism provides power for the rotation of the roller 13 to ensure that the material continuously tumbles inside the roller 13.

[0037] The tilting of the heating device, combined with the rotation of the drum 13, enables the material to tumble fully within the drum 13, making full use of the heat released by the steam, ensuring uniform heating of the material, and improving the drying effect. The sealed chamber 6 structure effectively reduces heat loss and improves heat utilization. The steam pipes 8 are arranged around the material and the steam holes are evenly distributed to ensure uniform steam release, further ensuring the uniformity of heating. The steam recycling design reduces energy consumption and lowers the drying cost of the material.

[0038] The height of the first support 2 is greater than the height of the second support 3. The first support 2 and the second support 3 are respectively supported at both ends of the outer cylinder wall 4. The upper surfaces of the first support 2 and the second support 3 are arc surfaces that fit the outer surface of the outer cylinder wall 4. Several flanges 33 are welded to both ends of the outer cylinder wall 4 along its circumferential direction. Several slots 34 are opened on the arc surfaces of the first support 2 and the second support 3. All slots 34 correspond one-to-one with all flanges 33. The flanges 33 are embedded in the slots 34.

[0039] In this embodiment, the height of the first support 2 is greater than the height of the second support 3. Both support the outer cylinder wall 4 at both ends. The upper surfaces of the first support 2 and the second support 3 are arc surfaces that fit the outer surface of the outer cylinder wall 4. This design allows the first support 2 and the second support 3 to fit tightly against the outer cylinder wall 4, providing stable support for the outer cylinder wall 4. Several flanges 33 are welded to both ends of the outer cylinder wall 4 in the circumferential direction. Correspondingly, the arc surfaces of the first support 2 and the second support 3 are provided with slots 34 corresponding to the flanges 33. The flanges 33 can be accurately embedded in the slots 34. This fit can effectively limit the axial movement of the outer cylinder wall 4 and ensure that the outer cylinder wall 4 remains stable during operation.

[0040] In this embodiment, the heating device can remain stable during operation, avoiding uneven heat transfer due to shaking or displacement, and ensuring the stability of the heating effect. The cooperation between the flange 33 and the slot 34 enhances the overall structural strength of the equipment, reduces component wear caused by vibration, lowers the probability of failure, extends the service life of the equipment, and ensures that the equipment can operate stably for a long time.

[0041] See drive mechanism Figure 1 As shown, the drive mechanism includes a ring-shaped gear ring 9, the inner diameter of which is larger than the outer diameter of the roller 13. The outer circumference of the gear ring 9 is integrally formed with a ring of regularly arranged gear teeth. The gear ring 9 is fitted onto the outside of the inner cylinder wall 5 of the roller 13. Several connecting blocks 10 are evenly distributed in the circumferential direction of the roller 13. The connecting blocks 10 are all located between the roller 13 and the gear ring 9. The lower surface of the connecting blocks 10 is fully welded to the outer surface of the roller 13, and the upper surface of the connecting blocks 10 is fully welded to the inner ring of the gear ring 9. A gear 11 meshes with the lower part of the gear ring 9. The gear 11 is rotatably connected to the worktable 1. A servo motor 12 is fixedly connected to the worktable 1 by bolts and nuts. The output shaft of the servo motor 12 is fixedly connected to the gear 11 by a flat key.

[0042] The servo motor 12 serves as a power source, driving the gear 11 to rotate, which in turn drives the gear ring 9 and the roller 13 to rotate.

[0043] The connection method of fully welding the connecting block 10 to the drum 13 and the connecting block 10 to the gear ring 9 ensures the firmness and stability of the connection between the gear ring 9 and the drum 13. It is not easy to loosen even when the drum 13 is rotating at high speed or under heavy load, thus ensuring the reliability of power transmission. The meshing transmission between the gear ring 9 and the gear 11 can ensure the stable rotation speed of the drum 13, so that the movement state of the material in the drum 13 remains consistent, thereby improving the material processing effect.

[0044] A steam generator is fixedly installed on workbench 1 using bolts and nuts. The steam generator includes a water inlet and a steam outlet. The steam outlet is connected to the steam pipe 8. A water inlet pipe is connected to the water inlet, and a water pump is installed on the water inlet pipe. The water inlet pipe is connected to the chamber 6 and a water outlet pipe 20 is connected to it. The water outlet pipe 20 is located at the bottom end along the inclined direction of the chamber 6, and a drain valve is installed on the water outlet pipe 20.

[0045] Steam generated by the steam generator enters the steam pipe 8, which is used to transport the steam to the chamber 6 to heat the material. After the steam releases heat, it condenses into liquid water. Since the heating device is set at an angle, the condensate flows to the bottom of the chamber 6 and gradually accumulates at the bottom along the angle of the chamber 6.

[0046] A steam trap is installed on the outlet pipe 20. The steam trap only allows condensate to be discharged through the outlet pipe 20, while preventing steam leakage. After the condensate enters the outlet pipe 20 through the steam trap, it is transported back to the inlet pipe of the steam generator 21 under the drive of the water pump 22. Finally, it is reheated into steam by the steam generator 21 and enters the steam pipe 8. This invention not only ensures that the chamber 6 is always filled with efficiently heated steam, but also realizes the recycling of water resources.

[0047] like Figure 3 As shown, two rings of rollers are evenly arranged along the axial direction on the outer surface of the roller 13. Each ring of rollers includes several rollers 15 evenly distributed along the circumferential direction of the roller 13. A rotating shaft is inserted inside the roller 15, and the roller 15 is rotatably connected to the rotating shaft. The two ends of the rotating shaft are respectively welded to two rods welded to the roller 13. The inner cylinder wall 5 has an annular groove 14. The position of the annular groove 14 corresponds to the position of the roller group. All rollers 15 in the roller group are inserted into the annular groove 14 and are connected by rolling along the annular groove 14.

[0048] The combination of the roller assembly and the annular groove 14 provides a stable support structure for the drum 13, ensuring that the drum 13 will not deviate or shake during rotation, making the movement trajectory of the material in the drum 13 more stable, which is conducive to the uniform drying of the material.

[0049] The structural design of the roller and the annular groove 14 enables the roller 13 to rotate stably within the inner cylinder wall 5. At the same time, the cooperation between the roller 15 and the annular groove 14 can limit the radial movement of the roller 13, reduce the shaking during rotation, help extend the service life of the roller 13 and related components, and reduce maintenance costs.

[0050] A sealing cover 16 is welded inside the feed inlet of the roller 13. The sealing cover 16 has a feed hole. A feed pipe 7 is fixedly connected to the worktable 1 by bolts and nuts. An air inlet pipe 17 is connected to the feed pipe 7. The feed pipe 7 extends into the feed hole. An air inlet ring 18 is welded to one end of the feed pipe 17 that extends into the feed hole. A first branch pipe 19 is connected between the feed pipe 17 and the air inlet ring 18. A second branch pipe 21 is connected to the air inlet ring 18. The first branch pipe 19 and the second branch pipe 21 are connected. Air outlet holes are evenly distributed in the direction of the air inlet ring 18 toward the inside of the roller 13. The air inlet ring 18 is located on the inner side of the sealing cover 16 toward the inside of the roller 13. The air inlet ring 18, the sealing cover 16 and the roller 13 are all clearance fit. A blower 18 is connected to the air inlet pipe 17. The blower 18 is fixed to the worktable 1 by bolts and nuts.

[0051] like Figure 2 As shown, several lifting plate groups are evenly distributed inside the drum 13. The lifting plate groups are evenly distributed along the axial direction of the drum 13. Each lifting plate group includes several first lifting plates 35 and several second lifting plates 36. Several first lifting plates 35 are circumferentially welded inside the drum 13. Each second lifting plate 36 is disposed between two adjacent first lifting plates 35. The second lifting plate 36 includes a fixing rod and an arc-shaped plate. One end of the fixing rod is welded inside the drum 13, and the arc-shaped plate is hinged to the other end of the fixing rod. The first lifting plates 35 are arc-shaped. One end of the first lifting plate 35 is welded to the inner wall of the drum 13, and the other end extends into the drum 13.

[0052] When the drum 13 rotates, the first lifting plate 35 can lift the material to a certain height, and then the material falls onto the second lifting plate 36 under the action of gravity. The second lifting plate 36 can prolong the time for the material to fall from the top to the bottom, so that the material can be more fully dispersed inside the drum, and the drying effect of the material from the inside to the outside is better.

[0053] The lifting plate assembly ensures that the material is continuously lifted, dropped, and turned inside the drum 13, improving the uniformity of material heating, promoting the drying process, and ensuring that the material is processed more thoroughly. It also guarantees that the material has sufficient residence time inside the drum 13, allowing the material to complete the drying process more fully and improving the efficiency and quality of material processing.

[0054] An installation bracket 22 is fixedly connected to the outer cylinder wall 4 by bolts and nuts. An exhaust fan 23 is detachably connected to the installation bracket 22 by bolts and nuts. The installation bracket 22 can effectively support the weight of the exhaust fan 23 and the vibration generated during operation. The installation of the exhaust fan 23 can accelerate the airflow inside the drum 13 and improve the drying efficiency of the material.

[0055] The detachable design facilitates the installation, disassembly, and maintenance of the exhaust fan 23. When it is necessary to inspect the equipment or replace parts, the exhaust fan 23 can be quickly disassembled, making the operation convenient and quick.

[0056] The above are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
