Description

Technical Field

[0001] The invention belongs to the technical field of drying furnaces, in particular to an automatic rotary drying furnace. Background Art

[0002] The double cone rotary dryer is a double cone rotary tank. In the vacuum state, steam or hot water is introduced into the jacket for heating. The heat contacts the wet material through the inner wall of the tank. The water vapor evaporated after the wet material absorbs heat is sucked away through the steam suction head and steam suction tube. The rotation of the tank makes the material constantly turn up and down, inside and outside, so it speeds up the drying speed of the material, improves the drying efficiency, and achieves the purpose of uniform drying. The moisture inside the material diffuses to the surface through the pressure difference or concentration difference. The water molecules (or other non-condensable gases) obtain enough kinetic energy on the surface of the material, and diffuse to the low-pressure space after overcoming the mutual attraction between molecules, and are sucked away by the vacuum pump to complete the separation from the solid.

[0003] A patent application with publication number CN116839319A discloses a double-cone rotary dryer, which avoids the problems of difficult separation and uncontrollable after using grinding balls, has high drying efficiency, fully mixes the materials in the dryer, increases the contact area between the materials and their internal heat source, and utilizes flipping in the horizontal and vertical directions to reduce the probability of material agglomeration. It is highly practical and suitable for popularization and use.

[0004] However, there are still certain problems in the above technology. When the material is rotated, the material to be dried will inevitably adhere to the outside of the vacuum collection hood during the drying process due to the moisture and sticky substances on the surface. This adhesion phenomenon is not only difficult to avoid, but will gradually accumulate and then block the filter holes. Once the filter holes are blocked, it will seriously hinder the smooth passage of water vapor, resulting in the vacuum collection hood being unable to effectively absorb and remove water vapor. In this way, the water vapor inside the drying equipment cannot be discharged in time, which will greatly affect the subsequent drying effect, making it impossible for the material to reach the expected degree of dryness, and may even cause a series of problems such as equipment failure and increased energy consumption.

[0005] To this end, the present invention provides an automatic rotary drying furnace. Summary of the invention

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 9As shown, an automated rotary drying furnace according to an embodiment of the present invention comprises an outer tank body 1, a driving drum 2 is fixedly mounted on one side of the outer tank body 1, a driven air-guiding drum 3 is fixedly mounted on the side of the outer tank body 1 away from the driving drum 2, a support frame 4 is mounted on the outer sides of the driving drum 2 and the driven air-guiding drum 3 through bearings, a rotary drive assembly is mounted inside the support frame 4, an inner tank body 7 is mounted inside the outer tank body 1, a steam extraction assembly is mounted inside the driving drum 2 through bearings, the steam extraction assembly is used to extract steam from the inner tank body 7, the steam extraction assembly comprises a steam suction pipe 8, one end of the steam suction pipe 8 is fixedly connected to a steam suction head 9, A protective suction hood 10 is rotatably mounted on the outside of the steam suction head 9 through a bearing, a suction hole 11 is opened on the inside of the protective suction hood 10, an anti-blocking component is installed on the outside of the protective suction hood 10, the anti-blocking component includes a scraping component and a filter hole cleaning component, the scraping component includes a push scraping rod 13, the anti-blocking component includes a moving push block 15 and a plastic insert 16, the moving push block 15 and the plastic insert 16 are both movably mounted on the inside of the protective suction hood 10, the scraping component scrapes the outside of the protective suction hood 10 through the push scraping rod 13, the anti-blocking component drives the plastic insert 16 to move to clear the suction hole 11 through the moving push block 15 under the push of the push scraping rod 13, and the driven A heating component is installed inside the air-guiding drum 3, and the heating component is used to heat the inner tank body 7. When working, the material can first be added into the inner tank body 7 from the feed port on the top of the outer tank body 1, and then the outside of the inner tank body 7 is heated by the heating component to dry the material inside the inner tank body 7. In addition, the driving component can be started. After the driving component is started, the outer tank body 1 can be driven to rotate, so that the material is turned over inside the inner tank body 7, so that the material will not accumulate at a certain position inside the inner tank body 7, thereby improving the drying effect. In addition, the steam extraction component can be used to extract the evaporated water vapor from the inner tank body 7, and the steam can be extracted by the steam extraction component. The steam suction pipe 8 is externally connected to a vacuum pump, and the vacuum pump can extract the water vapor evaporated by material drying inside the inner tank body 7 through the steam suction pipe 8 and the steam suction head 9 to ensure the drying effect. In addition, the scraper component and the anti-blocking component provided can prevent the material from adhering to and blocking the surface of the protective suction cover 10 and the inside of the suction hole 11. The outside of the protective suction cover 10 and the inside of the suction hole 11 can be cleaned to ensure that the water vapor produced by the material drying is stably exhausted. This can not only avoid the reduction in drying efficiency caused by the accumulation of water vapor inside the inner tank body 7 due to the clogging of the suction hole 11 by the material, but also can ensure that the drying effect of the material reaches the best state to the greatest extent.

[0033] like Figures 1 to 3As shown, the rotary drive assembly includes a driving motor 5, and a transmission wheel 6 is fixedly installed on the output end of the driving motor 5 and the outer side of the active drum 2, and a transmission belt is sleeved on the outer side of the transmission wheel 6; when working, after the driving motor 5 is started, the output end of the driving motor 5 can drive the transmission wheel 6 fixedly connected to the output end of the driving motor 5 to rotate, and drive the transmission wheel 6 fixedly installed on the outer side of the active drum 2 to rotate through the transmission belt, so that the outer tank body 1 is driven to rotate through the active drum 2, thereby driving the inner tank body 7 to rotate, and turning the material inside the inner tank body 7. Such a turning operation can ensure that the material will not accumulate at a certain position inside the active drum 2 for a long time during the drying process, but can continuously change its position and receive more uniform and sufficient heat transfer. In this way, not only can the drying efficiency of the material be significantly improved, but also the uniformity and consistency of the drying effect can be ensured.

[0034] like Figures 1 to 9 As shown, the scraper assembly also includes a mounting ring 12 and a rotating impeller 14, the push scraper rod 13 is fixedly mounted on the top of the mounting ring 12, the mounting ring 12 is fixedly mounted on the outside of the steam suction head 9, and the rotating impeller 14 is fixedly mounted on the top of the protective suction cover 10; during operation, when the inner tank body 7 is turned over, the material inside it will constantly change its position, and part of the material will fall on the top of the rotating impeller 14, impacting the top of the rotating impeller 14, thereby giving the rotating impeller 14 a driving force, so that the rotating impeller 14 rotates, although a part of the wet material will adhere to the surface of the rotating impeller 14 in the early stage, but with the operation of the device, the material inside the inner tank body 7 and the surface of the rotating impeller 14 will adhere to the rotating impeller 14. The attached materials will tend to dry, and subsequently, the materials on the surface of the rotating impeller 14 will be knocked off by the flipping of the inner tank body 7, which will not affect the normal operation of the rotating impeller 14, thereby driving the protective suction hood 10 to rotate on the top of the steam suction head 9. When the protective suction hood 10 rotates, the push-scraping rod 13 can scrape the outside of the protective suction hood 10 to prevent the materials from adhering to the surface of the protective suction hood 10 and blocking the suction hole 11, thereby ensuring the stable extraction of the water vapor produced by the material drying, and the rotating protective suction hood 10 can also make it difficult for the materials to contact the surface of the protective suction hood 10 when rolling and moving, further reducing the possibility of adhesion and ensuring the drying effect.

[0035] like Figures 1 to 9As shown, spring pressure blocks 17 are fixedly installed on both sides of the movable push block 15, two spring grooves 19 are provided inside the protective suction cover 10, and the spring pressure blocks 17 are slidably installed on the inner sides of the two spring grooves 19 respectively, and return springs 18 are installed inside the two spring grooves 19, one end of the return spring 18 is fixedly connected to the spring pressure block 17, and the other end of the return spring 18 is fixedly connected to the inner wall of the spring groove 19, the plastic insert 16 is made of plastic aluminum alloy, and the end of the plastic insert 16 away from the movable push block 15 is in a pointed cone shape, and the pointed cone end of the plastic insert 16 is located on the inner side of the suction hole 11, The end of the moving push block 15 away from the plastic insert 16 is located outside the protective suction cover 10, and the end of the moving push block 15 away from the plastic insert 16 is inclined clockwise, and a repeated poking component 1 is installed inside the plastic insert 16, and a repeated poking component 2 is installed outside the plastic insert 16. The plastic insert 16 clears the suction hole 11 through the repeated poking component 1 and the repeated poking component 2; when working, when the protective suction cover 10 rotates, the moving push block 15 and the plastic insert 16 can be driven to rotate, and when the moving push block 15 passes through the push scraper rod 13, the push scraper rod 13 can resist the moving push block 15 The end of the moving push block 15 located outside the protective suction cover 10 is inclined, which can facilitate the push and scraper rod 13 to pass through the moving push block 15 to resist the moving push block 15, so that the moving push block 15 is completely immersed in the interior of the protective suction cover 10, thereby pushing the plastic insert 16 to move inside the protective suction cover 10, so that the pointed cone-shaped end of the plastic insert 16 moves inside the suction hole 11, thereby poking the materials accumulated inside the suction hole 11, which can not only prevent the problem of material blockage that may occur in the future and ensure the long-term stable operation of the drying equipment, but also can realize the already blocked suction hole 11 The push and scraper rod 13 can be unblocked to ensure stable extraction of the water vapor produced by material drying and normal drying of the material. In addition, after the push and scraper rod 13 passes through the movable push block 15, the spring pressure block 17 can be pushed to move inside the spring groove 19 under the action of the elastic force of the reset spring 18. On the one hand, the position of the movable push block 15 and the plastic insert 16 is reset. On the other hand, the elastic force of the reset spring 18 can push the spring pressure block 17 to collide with the spring groove 19, so that the movable push block 15 and the plastic insert 16 produce a certain amplitude of vibration, thereby facilitating the shaking off of the material adhering to the end of the plastic insert 16.

[0036] like Figures 1 to 9As shown, the repeated poking and inserting component 1 includes a pressing block 20 and an auxiliary inserting strip 1 22. One side of the pressing block 20 is inclined. The auxiliary inserting strip 1 22 is movably installed inside the plastic inserting strip 16. One end of the auxiliary inserting strip 1 22 is slidably installed on the inclined surface of the pressing block 20, and the end of the auxiliary inserting strip 1 22 away from the pressing block 20 is triangularly inclined. A rectangular groove 25 is provided inside the plastic inserting strip 16. The pressing block 20 is slidably installed on the inner side of the rectangular groove 25. An elastic rubber strip 21 is fixedly installed between the bottom of the pressing block 20 and the rectangular groove 25. A mounting groove 27 is provided inside the protective suction cover 10. Two fixed pressure strips 28 are fixedly installed inside the mounting groove 27. One end of the fixed pressure strip 28 contacts the surface of the plastic inserting strip 16. A pressing protrusion 41 is fixedly installed inside the suction hole 11. During operation, when the plastic inserting strip 16 moves in the direction close to the suction hole 11 inside the protective suction cover 10, the pressing block 20 will pass through the fixed pressure strip 28. At this time, the fixed pressure The strip 28 will resist the installation groove 27, thereby pushing the pressing block 20 into the inside of the rectangular groove 25. When the pressing block 20 moves, one end of the auxiliary inserting strip 22 will move along the inclined surface of the pressing block 20, thereby pushing the auxiliary inserting strip 22 to move in the direction close to the suction hole 11. When the triangular inclined end of the auxiliary inserting strip 22 passes through the pressing protrusion 41, the pressing protrusion 41 will apply a pressing force to the triangular inclined end of the auxiliary inserting strip 22, thereby causing the plastic inserting strip 16 to produce In addition, when the plastic insert 16 is reset by the reset spring 18, when the pressing block 20 no longer presses the fixed pressure strip 28, the pressing block 20 will be reset under the elastic force of the elastic rubber strip 21, thereby pulling the auxiliary insert 1 22 to reset, so that the pressing protrusion 41 will no longer press the auxiliary insert 1 22, so that the plastic insert 16 recovers its deformation, and the material remaining on the surface of the pointed cone end of the plastic insert 16 is shaken off by the swinging force of the recovery deformation.

[0037] like Figures 1 to 9As shown, the repeated poking and inserting assembly 2 includes a rotating block 29 and an auxiliary inserting strip 24. The outer side of the rotating block 29 contacts one side of the auxiliary inserting strip 24. The auxiliary inserting strip 24 is slidably installed on the inner side of the plastic inserting strip 16. A connecting strip 23 is fixedly installed on one end of the auxiliary inserting strip 24. The end of the auxiliary inserting strip 24 away from the connecting strip 23 is in a pointed cone shape. In the initial state, the pointed cone end face of the auxiliary inserting strip 24 is in the same plane as the pointed cone face of the plastic inserting strip 16. The connecting strip 23 is away from the auxiliary inserting strip. One end of the second strip 24 is fixedly connected to one side of the auxiliary inserting strip 1 22, the rotating block 29 is rotatably mounted on the inner side of the plastic inserting strip 16, and the outer side of the rotating block 29 is fixedly mounted with an auxiliary inserting strip 3 30, and the end of the auxiliary inserting strip 3 30 away from the rotating block 29 is in a pointed cone shape, and a moving groove 26 is opened inside the plastic inserting strip 16, and the connecting strip 23 is slidably mounted on the inner side of the moving groove 26; when working, the auxiliary inserting strip 1 22 can drive the connecting strip 23 to move inside the moving groove 26 when moving. The moving direction of the auxiliary insert strip 1 22 is the same as the moving direction of the auxiliary insert strip 2 24. When the auxiliary insert strip 1 22 and the auxiliary insert strip 2 24 move toward the direction close to the suction hole 11 at the same time, the auxiliary insert strip 2 24 can push down the material remaining at the pointed cone end of the plastic insert strip 16 to prevent the material from accumulating at the pointed cone end of the plastic insert strip 16, and when the auxiliary insert strip 24 moves toward the direction close to the suction hole 11 of the protective suction cover 10, the friction force can be used to drive the rotating block 29 to rotate, so that the auxiliary insert strip 3 30 moves toward the direction close to the inlet of the suction hole 11, and pokes the material remaining inside the suction hole 11 to prevent the material from accumulating inside the suction hole 11, thereby improving the cleaning effect of the suction hole 11, ensuring that the water vapor produced by the material drying is stably exhausted, and ensuring the normal drying of the material. In addition, when the auxiliary insert strip 24 follows the auxiliary insert strip 1 22 to move in the direction away from the suction hole 11, it can drive the auxiliary insert strip 24 to reset, thereby improving the use effect of the device.

[0038] like Figures 1 to 3 As shown, a collecting bucket 38 is fixedly installed on the top and bottom of the inner cavity of the inner tank body 7, a feeding trough 39 is opened inside the collecting bucket 38, and a drop pipe 40 is connected to the opposite side of the collecting bucket 38; during operation, when the inner tank body 7 is turned over, part of the material will enter the interior of the collecting bucket 38 through the feeding trough 39, and this part of the material will not be quickly turned over with the rest of the material, and the granular material inside the collecting bucket 38 will be discharged through the drop pipe 40. When the outer tank body 1 and the inner tank body 7 are in a vertical state, the end of the drop pipe 40 away from the collecting bucket 38 will be located directly above the rotating impeller 14, so that the material inside the collecting bucket 38 can be discharged through the drop pipe 40 to impact the surface of the rotating impeller 14, which can ensure that the rotating impeller 14 must be in a rotating state, ensure the normal operation of the anti-blocking component, and can maximize the guarantee that the drying effect of the material reaches the best state.

[0039] like Figures 1 to 3As shown, a heating component is installed inside the driven air-guiding drum 3, and the heating component is used to heat the inner tank body 7. The heating component includes a cold source outlet pipe 32 and a heat source inlet pipe 33. The top of the cold source outlet pipe 32 is fixedly connected with a connecting seat 31. One end of the connecting seat 31 is rotatably connected to the end of the driven air-guiding drum 3 away from the outer tank body 1, and the heat source inlet pipe 33 is rotatably installed on the inner side of the connecting seat 31 through a bearing. When working, an external heating pipeline can be connected through the heat source inlet pipe 33, and heating gas can be added to the inner side of the outer tank body 1 through the heat source inlet pipe 33, so as to heat the outer side of the inner tank body 7 and dry the material inside the inner tank body 7. In addition, the hot air with reduced temperature can be discharged into the driven air-guiding drum 3 The hot air is then transmitted to the inside of the rotating drum 3 and then to the connecting seat 31, and then transported to the inside of the cold source outlet pipe 32 through the connecting seat 31, and then discharged through the cold source outlet pipe 32 to the external cold transport pipeline to discharge the cooled hot air, and the gas-wrapped method is used to heat the inner tank body 7, thereby avoiding the hot spot and cold spot problems that may occur in traditional heating methods. Since the heating gas can fully contact the surface of the inner tank body 7, the heat transfer is more efficient and uniform, thereby ensuring that the material inside the inner tank body 7 can also obtain a uniform heating effect. This heating method can not only significantly improve the drying efficiency of the material, but also effectively avoid the problem of material quality degradation due to uneven heating, thereby ensuring the quality and stability of the final product.

[0040] like Figures 1 to 3 As shown, a middle heat insulation tank 35 is fixedly installed inside the outer tank body 1, one end of the heat source inlet pipe 33 passes through the middle heat insulation tank 35 and extends between the middle heat insulation tank 35 and the inner tank body 7, and is fixedly connected with a heat source discharge head 34; when working, the outer tank body 1 and the inner tank body 7 can be separated into a heating chamber and a cooling chamber by the set middle heat insulation tank 35, so that the heated gas is isolated from the cooled gas, which can significantly improve the heating efficiency, and can effectively manage the energy flow of the entire system to ensure the maximization of the heating effect while maintaining the stability and sustainability of the system. The heat source discharge head 34 is located inside the heating chamber, and the heat source discharge head 34 adopts a structure with holes opened all around the cylinder, which can disperse the hot gas.

[0041] like Figures 1 to 3 As shown, blocking rings 36 are fixedly installed on the top and bottom of the inner tank body 7, and connecting grooves 37 are opened inside the blocking rings 36. The connecting grooves 37 are opened on the side of the blocking rings 36 away from the heat source discharge head 34; when working, the top and bottom of the space between the inner tank body 7 and the middle insulation tank 35 can be blocked by the setting of the blocking rings 36, so that the hot air discharged from the heat source discharge head 34 will not quickly enter between the outer tank body 1 and the middle insulation tank 35. The hot gas needs to diffuse to the side of the inner tank body 7 and the inner cavity of the middle insulation tank 35 away from the heat source discharge head 34 before it can pass through the blocking rings 36 to enter between the outer tank body 1 and the middle insulation tank 35, thereby ensuring the high efficiency and uniformity of heat transfer.

[0042] Working principle: First, the material can be added into the inner tank body 7 from the feed port at the top of the outer tank body 1, and the heat supply pipeline can be connected to the heat source inlet pipe 33. The heating gas can be added to the inner side of the outer tank body 1 through the heat source inlet pipe 33, so as to heat the outer side of the inner tank body 7 and dry the material inside the inner tank body 7. In addition, the hot air with reduced temperature can be discharged into the interior of the driven air guide drum 3, and then transmitted to the connecting seat 31, and then transported to the interior of the cold source outlet pipe 32 through the connecting seat 31, and then connected to the cold source outlet pipe 32 through the cold source outlet pipe 32. The cooled hot air is discharged , the inner tank body 7 is heated by gas wrapping, which avoids the hot spot and cold spot problems that may occur in traditional heating methods. Since the heating gas can fully contact the surface of the inner tank body 7, the heat transfer is more efficient and uniform, thereby ensuring that the material inside the inner tank body 7 can also obtain a uniform heating effect, and the material inside the inner tank body 7 is dried. In addition, the drive motor 5 can be started. After the drive motor 5 is started, the output end of the drive motor 5 can drive the transmission wheel 6 fixedly connected to the output end of the drive motor 5 to rotate, and drive the transmission wheel 6 fixedly installed on the outside of the active drum 2 to rotate through the transmission belt, so that the outer tank body 1 is driven to rotate through the active drum 2, thereby driving the inner tank body 7 to rotate, and turning the material inside the inner tank body 7. Such a turning operation can ensure that the material will not accumulate at a specific position inside the active drum 2 for a long time during the drying process, but can continuously change its position and receive more uniform and sufficient heat transfer. In addition, the steam extraction component can be used to extract the evaporated water vapor inside the inner tank body 7, and the steam suction pipe 8 is connected to an external vacuum pump. The vacuum pump is connected to the steam suction pipe 8 and The steam suction head 9 can extract the water vapor evaporated by material drying inside the inner tank body 7 to ensure the drying effect. In addition, the scraper component and anti-clogging component can prevent the material from adhering to the surface of the protective suction cover 10 and the inside of the suction hole 11. The outside of the protective suction cover 10 and the inside of the suction hole 11 can be cleaned to ensure that the water vapor produced by the material drying is stably exhausted. This can not only avoid the reduction in drying efficiency caused by the accumulation of water vapor inside the inner tank body 7 due to the clogging of the suction hole 11 by the material, but also can ensure that the drying effect of the material reaches the best state to the greatest extent.
