Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and in particular to a horizontal split-type circulating drying equipment. Background Technology

[0002] In numerous fields such as agricultural and sideline product processing, food production, chemical building materials, and traditional Chinese medicine processing, material drying and dehydration are crucial processes for ensuring product quality, extending shelf life, and improving processing efficiency. Rotary drum dryers, with their advantages of large processing capacity, strong continuous operation capability, wide applicability to a wide range of materials, and stable and reliable operation, have become one of the most widely used drying equipment in industrial production. Through the rotation of the drum, the material is continuously turned over, allowing for full contact and heat exchange between the material and hot air, achieving rapid and uniform drying. This meets the needs of large-scale, continuous industrial production and is a core piece of equipment supporting modern production in various industries.

[0003] Existing drum drying equipment generally suffers from the following defects: the dehumidification system mostly adopts a normally open exhaust port design, and a large amount of hot air that has not been fully heat-exchanged is discharged along with the humid air during the drying process, resulting in extremely low heat energy utilization and high energy consumption; at the same time, the existing equipment's stirring structure and discharge structure are independent of each other, the structure is complex, the discharge is incomplete, and residual materials are easy to cause cross-contamination between different batches of products. Summary of the Invention

[0004] In view of the technical problems of existing drum drying equipment mentioned in the background art, the present invention provides a horizontal split-type circulating drying equipment.

[0005] The technical solution adopted in this invention is: a horizontal split-type circulating drying device, comprising: A base, on which an I-beam is fixedly connected; The roller has a feed inlet at its top and a side door detachably connected to the top of the feed inlet.

The first motor is fixedly connected to the top of the I-beam. The gear is fixedly connected to the output end of the first motor and meshes with the gear ring. A guide strip is fixedly connected to the outside of the drum. A guide roller is rotatably connected to the outside of the I-beam and abuts against the guide strip. A support base is also fixedly connected to the top of the I-beam. Two sets of limiting rollers are rotatably connected to the top of the support base and abut against the side wall of the guide strip.

[0009] In a further embodiment of the present invention, the second drive component is a second motor fixedly connected to the outside of the moving frame, the output end of the second motor is fixedly connected to the rotating shaft coaxially, and multiple sets of mounting seats are fixedly connected to the outside of the rotating plate, and rotating rollers are rotatably connected to the outside of the mounting seats.

[0010] In a further embodiment of the present invention, the third moving component includes a third motor fixedly connected to the outside of the I-beam and a threaded rod fixedly connected to the output end of the third motor. A nut block is threadedly connected to the outside of the threaded rod, and the nut block is fixedly connected to the moving frame. A limit rod is fixedly connected to the outside of the I-beam, and a slide tube is slidably sleeved on the outside of the limit rod. The slide tube is fixedly connected to the moving frame.

[0011] A further configuration of the present invention is that the intermittent opening component includes an arc-shaped block and an abutment block. A fixing rod is fixedly connected to the bottom of the abutment block, and the fixing rod is fixedly connected to a fixing cylinder. A guide rod is fixedly connected to the outside of the arc-shaped block, and a fixing block is slidably sleeved on the outside of the guide rod. A connecting rod is fixedly connected to the bottom of the fixing block, and the connecting rod is fixedly connected to one of the mounting seats. A fixing bolt is threaded through the fixing block, and one end of the fixing bolt abuts against the outer wall of the guide rod. Multiple sets of sliding rollers are rotatably connected to the outside of the arc-shaped block.

[0012] A further configuration of the present invention is that multiple sets of buffer blocks are fixedly connected to the outside of the scraper, one end of the roller is provided with a through hole, a rectangular rod is fixedly connected to the outside of the scraper, the rectangular rod is provided with an insertion hole, a side frame is fixedly connected to the outside of the base, a pin is provided through the side frame, and a through hole is provided at the position of the rectangular rod on the outside of the side frame, through which the rectangular rod passes.

[0013] A further configuration of the present invention is that the outside of the rotating plate is provided with an abutment ring, the outside of the abutment ring is connected to a plurality of first balls, the outside of the movable frame is fixedly connected to a sleeve, a sleeve rod is slidably connected in the sleeve, one end of the sleeve rod is fixedly connected to the abutment ring, and a spring is connected between the sleeve rod and the sleeve.

[0014] A further feature of the present invention is that the base is provided with a discharge port.

[0015] The beneficial effects of this invention are: Compared with existing technologies, the dual-rotation design of the drum and stirring blades in this invention enables the material to be double-turned and dispersed within the drum, preventing material agglomeration and ensuring full contact and heat exchange with hot air, significantly improving drying uniformity and efficiency, and significantly shortening the drying cycle. The intermittent dehumidification structure intermittently opens the fixed cylinder opening during the rotation of the rotating plate, which can promptly discharge the high-humidity air generated during drying, preventing the material from becoming damp again, and also minimize the loss of hot air, significantly improving heat energy utilization and reducing drying energy consumption. The cooperative structure of the synchronous sliding assembly ensures that the rotating shaft and the sliding sleeve rotate synchronously to achieve stirring and dehumidification functions, while also allowing axial sliding, providing reliable transmission for the intermittent opening and closing of the rotating plate and the scraper discharge. During the discharge process, the movement of the scraper can quickly and thoroughly push the material out of the drum.

[0016] II. Compared with existing technologies, this invention employs an intermittent dehumidification structure with rotating plates, eliminating the design flaws of traditional drum dryers with normally open exhaust vents. During the drying process, the rotating plates rotate synchronously with the shaft. Through the intermittent contact between the arc-shaped blocks and the contact blocks, the opening of the fixed cylinder is automatically opened and closed periodically. This intermittent dehumidification method can open the opening in time when high-humidity air accumulates, quickly expelling the large amount of water vapor generated during drying, avoiding problems such as material re-dampening and uneven drying due to excessive internal humidity. It can also automatically close the opening during the dehumidification intervals, minimizing the leakage of hot air that has not been fully exchanged, significantly improving heat energy utilization, and greatly reducing drying energy consumption. Compared with traditional normally open dehumidification, intermittent dehumidification can effectively reduce heat loss while ensuring drying efficiency. It also prevents large amounts of cold air from entering the drying chamber, causing temperature fluctuations and ensuring the stability of the drying temperature. This results in more uniform drying and more consistent quality of the material, perfectly adapting to the continuous drying needs of various materials.

[0017] Third, compared with existing technologies, the arc-shaped block in this invention adopts an adjustable extension distance structure. Through the sliding cooperation between the guide rod and the fixed block, and with the quick locking of the fixing bolts, the extension length of the arc-shaped block can be flexibly adjusted, thereby precisely controlling the outward opening range and dehumidification volume of the rotating plate. This solves the pain point that traditional fixed-opening dehumidification structures cannot adapt to the needs of different materials and different drying stages: for materials with high moisture content, the extension distance of the arc-shaped block can be increased, increasing the opening range of the rotating plate and improving the dehumidification speed, avoiding the material being in a high-humidity environment for a long time; for materials with low moisture content or in the later stages of drying, the extension distance of the arc-shaped block can be reduced, reducing the dehumidification volume, further reducing heat loss and saving energy. At the same time, the dehumidification intensity can be flexibly adjusted according to the particle size, bulk density, and other characteristics of the material, avoiding excessive dehumidification that causes lightweight materials to be carried out by the airflow, or insufficient dehumidification that leads to incomplete drying. The adjustment method is simple and convenient, requiring no replacement of any parts.

[0018] IV. Compared with existing technologies, in this invention, the synchronous sliding assembly adopts a mating structure of arc-shaped grooves and second rolling balls. Multiple symmetrically distributed arc-shaped grooves ensure uniform force distribution on the shaft and sleeve, avoiding component deformation and uneven wear caused by unilateral force. The second rolling ball transforms traditional sliding friction into rolling friction, significantly reducing the frictional resistance between the sleeve and shaft, making the axial sliding of the sleeve on the shaft smoother and more seamless, resulting in higher transmission efficiency and effectively reducing drive energy consumption. Simultaneously, rolling friction significantly reduces component wear, extends the service life of the synchronous sliding assembly, and lowers the equipment's maintenance frequency and costs.

Therefore, they should not be construed as limitations on this invention.

[0022] The following is in conjunction with the appendix Figure 1-12 The present invention will be further described below.

[0023] To address the problems existing in the background art, this application proposes the following technical solution: a horizontal split-type circulating drying device, comprising: a base 1, a drum 2, a rotating plate 24, a synchronous sliding assembly, a moving frame 37, and an intermittent opening assembly; the base 1 is provided with a discharge port 4. (Refer to...) Figure 1 The base 1 can actually be set as an inclined structure to prevent material from being discharged through the opening side of the fixed cylinder 11 during the drying process. An I-beam 3 is fixedly connected to the base 1. The top of the drum 2 is provided with a feed inlet, and a side door 13 is detachably connected to the top of the feed inlet. The drum 2 is rotatably positioned above the I-beam 3. The outside of the I-beam 3 is provided with a first drive assembly for driving the drum 2 to rotate. The fixed cylinder 11 is fixedly connected to the outside of the I-beam 3. One end of the drum 2 is rotatably connected to the fixed cylinder 11. The outside of the fixed cylinder 11 is an open structure. An air inlet pipe 15 is fixedly connected to the fixed cylinder 11. A rotating plate 24 is located on the outside of the fixed cylinder 11. A sliding sleeve 35 is fixedly connected to the outside of the rotating plate 24. A rotating shaft 31 is passed through the sliding sleeve 35. A scraper 42 is fixedly connected to the end, and an agitator 32 is fixedly connected to the outside of the rotating shaft 31. A synchronous sliding assembly is provided between the sliding sleeve 35 and the rotating shaft 31. The synchronous sliding assembly enables the rotating shaft 31 to drive the sliding sleeve 35 to rotate synchronously, and also enables the sliding sleeve 35 to slide outside the rotating shaft 31. The moving frame 37 is set above the I-beam 3. The rotating shaft 31 is rotatably connected to the moving frame 37. A second driving assembly for driving the rotating shaft 31 to rotate is provided outside the moving frame 37. A third moving assembly for driving the moving frame 37 to move is also provided on the I-beam 3. An intermittent opening assembly is set outside the rotating plate 24. When the rotating plate 24 rotates synchronously with the rotating shaft 31, it intermittently slides outward, thereby intermittently opening the opening side of the fixed cylinder 11 to achieve the discharge of humid air.

[0024] In this embodiment, the base 1 serves as the supporting foundation for the entire equipment. Its inclined structure guides the material towards the discharge port 4 (the inclination angle can be designed according to actual conditions, or a non-inclined design can be used), preventing material accumulation and leakage at the opening of the fixed cylinder 11, thus ensuring the sealing of the drying process. The I-beam 3 provides rigid support for core components such as the drum 2 and drive assembly, ensuring stable and vibration-free operation. The drum 2, as the drying chamber, rotates to tumble the material, allowing it to fully contact the hot air and improving drying uniformity. The detachable side door 13 facilitates feeding and internal maintenance, making operation convenient. The fixed cylinder 11 is rotatably connected to the drum 2, ensuring free rotation of the drum 2 while forming a closed drying space to prevent hot air leakage. The air inlet pipe 15 evenly delivers hot air into the drum 2, providing a continuous heat source for drying. The rotating plate 24, in conjunction with the intermittent opening assembly, enables intermittent discharge of humid air. Unlike traditional normally open exhaust ports, this not only promptly discharges high-humidity air to prevent material re-dampening but also minimizes hot air loss, significantly improving heat utilization and reducing drying energy consumption. The synchronous sliding assembly enables the synchronous rotation and axial sliding of the rotating shaft 31 and the sliding sleeve 35, providing a structural basis for the intermittent opening and closing of the rotating plate 24 and the material discharge of the scraper 42. The stirring blade 32 rotates synchronously with the rotating shaft 31, which can perform secondary stirring and dispersing of the material, preventing material agglomeration and further improving drying efficiency. The scraper 42 and the rotating shaft 31 are integrated into one unit. After drying, it can move as a whole with the moving frame 37 to completely scrape out the material in the drum 2, leaving no residue and preventing cross-contamination.

[0025] In this embodiment, a fixed frame 12 is fixedly connected to the I-beam 3, the fixed frame 12 is fixedly connected to the fixed cylinder 11, an annular slide rail 51 is fixedly connected to the outside of the roller 2, and an annular slide bar 49 is fixedly connected to the inner wall of the fixed cylinder 11. The annular slide bar 49 is slidably connected to the annular slide rail 51.

[0026] In the above technical solution, the fixing frame 12 provides stable support for the fixing cylinder 11, ensuring the coaxiality of the fixing cylinder 11 and the roller 2, and avoiding rotational jamming and sealing failure caused by eccentricity. The sliding cooperation between the annular slide rail 51 and the annular slide bar 49 provides guidance for the relative rotation of the roller 2 and the fixing cylinder 11.

[0027] In this embodiment, the synchronous sliding assembly includes an arc groove 33 and a second ball bearing 34. The arc groove 33 is provided in multiple sets and is symmetrically opened on the outer wall of the rotating shaft 31 and the inner wall of the sliding sleeve 35. The second ball bearing 34 is located in the arc groove 33. The sliding sleeve 35 is detachably connected to a side cover 36.

[0028] In the above technical solution, the synchronous sliding assembly adopts a mating structure of arc-shaped groove 33 and second ball bearing 34, perfectly realizing the dual functions of synchronous rotation and axial sliding of the rotating shaft 31 and the sliding sleeve 35. Multiple symmetrically distributed arc-shaped grooves 33 ensure uniform force distribution, avoiding component deformation caused by unilateral force. The second ball bearing 34 converts sliding friction into rolling friction, reducing the frictional resistance between the sliding sleeve 35 and the rotating shaft 31, making the axial sliding of the sliding sleeve 35 on the rotating shaft 31 smoother and more seamless, resulting in higher transmission efficiency, reduced component wear, and extended service life. The detachable side cover 36 facilitates the installation, replacement, and maintenance of the second ball bearing 34 without disassembling the entire rotating shaft 31 and sliding sleeve 35, significantly reducing maintenance difficulty and downtime. This structure ensures that the rotating plate 24 and the stirring blade 32 rotate synchronously with the rotating shaft 31 to achieve stirring and intermittent dehumidification functions, while also allowing the sliding sleeve 35 to slide freely along the axial direction of the rotating shaft 31. This provides a reliable transmission guarantee for the intermittent opening and closing of the rotating plate 24 and the material discharge action of the scraper 42. The structure is simple and compact, and the operation is stable and reliable.

[0029] In this embodiment, the first drive assembly includes a first motor 5, a gear 6, and a gear ring 18. The gear ring 18 is fixedly connected to the outside of the roller 2. The first motor 5 is fixedly connected to the top of the I-beam 3. The gear 6 is fixedly connected to the output end of the first motor 5 and meshes with the gear ring 18. A guide strip 7 is fixedly connected to the outside of the roller 2. A guide roller 8 is rotatably connected to the outside of the I-beam 3 and abuts against the guide strip 7. A support base 9 is also fixedly connected to the top of the I-beam 3. Two sets of limiting rollers 10 are rotatably connected to the top of the support base 9 and abut against the side wall of the guide strip 7.

[0030] In the above technical solution, the first drive component uses a gear 6 and a gear ring 18 meshing transmission to control the rotation speed of the drum 2 and adapt to the drying requirements of different materials. The gear ring 18 is fixed to the outside of the drum 2, with uniform force, capable of bearing the weight of the drum 2 and the material, and is not easily deformed during long-term operation. The cooperation between the guide roller 8 and the guide strip 7 provides radial support for the drum 2, ensuring the coaxiality of the drum 2's rotation and avoiding eccentric swaying. Two sets of limiting rollers 10 clamp the guide strip 7 from both sides, restricting the axial movement of the drum 2, preventing displacement of the drum 2 during rotation, and ensuring the sealing effect of the connection between the drum 2 and the fixed cylinder 11. The support base 9 provides stable support for the guide roller 8 and the limiting roller 10, ensuring stable operation. This drive and support structure works together to make the drum 2 rotate smoothly without swaying, and the material is tumbled evenly, avoiding the problem of local over-drying or under-drying, thus improving the drying quality and the reliability of equipment operation.

[0031] In this embodiment, the second drive component is a second motor 38 fixedly connected to the outside of the movable frame 37. The output end of the second motor 38 is fixedly connected to the rotating shaft 31 on the same axis. Multiple sets of mounting seats 26 are fixedly connected to the outside of the rotating plate 24, and rotating rollers 25 are rotatably connected to the outside of the mounting seats 26.

[0032] In the above technical solution, the second motor 38 drives the rotating shaft 31 to rotate without interfering with the first drive assembly. It can independently adjust the rotation speed of the stirring blades 32 and the rotating plate 24 according to the material characteristics, achieving control over the stirring intensity and dehumidification frequency, adapting to the drying needs of materials with different moisture contents and characteristics. The coaxial fixed connection ensures gapless transmission, direct and efficient power transmission, and guarantees the smoothness of the rotating shaft 31's rotation. The rotating roller 25 is installed outside the rotating plate 24 and rolls in contact with the end face of the fixed cylinder 11, converting the sliding friction between the rotating plate 24 and the fixed cylinder 11 into rolling friction, significantly reducing frictional resistance and making the rotation and axial sliding of the rotating plate 24 smoother, reducing component wear and operating noise. The mounting base 26 provides stable support for the rotating roller 25, ensuring flexible rotation and preventing jamming during long-term operation. This structure ensures stable implementation of stirring and dehumidification functions, reduces energy consumption and maintenance costs, and improves equipment operating efficiency.

[0033] In this embodiment, the third moving component includes a third motor 39 fixedly connected to the outside of the I-beam 3 and a threaded rod 40 fixedly connected to the output end of the third motor 39. The threaded rod 40 is externally threaded with a nut block, which is fixedly connected to the moving frame 37. A limit rod 41 is fixedly connected to the outside of the I-beam 3. A slide tube is slidably sleeved on the outside of the limit rod 41, which is fixedly connected to the moving frame 37.

[0034] In the above technical solution, the third moving component adopts a threaded transmission structure of threaded rod 40 and nut block, which ensures smooth transmission and operation and controls the moving distance and speed of the moving frame 37. The cooperation between the limit rod 41 and the slide tube provides guidance for the moving frame 37, preventing rotational deviation during movement and ensuring the straightness of the moving trajectory. The third motor 39 provides stable power, enabling automatic reciprocating movement of the moving frame 37 without manual operation. After drying, the third motor 39 drives the moving frame 37 to move outward, simultaneously driving the rotating shaft 31, scraper 42, rotating plate 24, and other components to slide outward as a whole. The scraper 42 can thoroughly scrape off the material adhering to the inner wall of the drum 2, achieving automatic discharge. The discharge is thorough and residue-free, avoiding cross-contamination between different batches of materials. This structure significantly improves discharge efficiency, reduces manual labor intensity, and ensures clean and thorough discharge, thereby improving product quality.

[0035] In this embodiment, the intermittent opening component includes an arc-shaped block 19 and an abutment block 17. A fixing rod 16 is fixedly connected to the bottom of the abutment block 17, and the fixing rod 16 is fixedly connected to the fixing cylinder 11. A guide rod 21 is fixedly connected to the outside of the arc-shaped block 19. A fixing block 20 is slidably sleeved on the outside of the guide rod 21. A connecting rod 23 is fixedly connected to the bottom of the fixing block 20, and the connecting rod 23 is fixedly connected to one of the mounting seats 26. A fixing bolt 22 is threaded through the fixing block 20, and one end of the fixing bolt 22 abuts against the outer wall of the guide rod 21. Multiple sets of sliding rollers 48 are rotatably connected to the outside of the arc-shaped block 19. In practice, the intermittent opening... The opening assembly can be set in multiple groups, not limited to one group. That is, the arc-shaped block 19 and related structural components can be fixedly connected to multiple mounting bases 26, and multiple sets of abutment blocks 17 can be fixedly connected to the outside of the fixed cylinder 11. In addition, the fixed block 20 has a sliding hole inside for the guide rod 21 to slide, and multiple sets of threaded holes can be set on the outside of the guide rod 21 for connection with the fixing bolt 22, further increasing the fixing effect between the fixing bolt 22 and the guide rod 21. The arc-shaped block 19 can be adjusted in distance through the guide rod 21, thereby realizing the distance of the turntable 24 opening outward, which can be adjusted according to different materials.

[0036] In the above technical solution, the intermittent opening component achieves the intermittent opening and closing of the rotating plate 24 through the intermittent contact between the arc-shaped block 19 and the contact block 17, thereby achieving the intermittent discharge of humid air. When the arc-shaped block 19 rotates with the rotating plate 24 to the position of the contact block 17, the arc-shaped block 19 is pushed by the contact force to slide the rotating plate 24 outward, opening the opening of the fixed cylinder 11 to discharge humid air; after the arc-shaped block 19 rotates past the contact block 17, the rotating plate 24 automatically resets and closes the opening under the action of the spring 50, reducing the loss of hot air. This intermittent dehumidification method can not only discharge the high-humidity air generated during drying in a timely manner, preventing the material from becoming damp again, but also avoid continuous leakage of hot air, greatly improving the thermal energy utilization rate and reducing the drying energy consumption. The arc-shaped block 19 can flexibly adjust its extension distance through the sliding cooperation between the guide rod 21 and the fixed block 20, thereby changing the opening range of the rotating plate 24 and realizing the adjustment of the dehumidification volume. Different materials have different moisture contents, and the dehumidification requirements vary at different stages of the drying process. The adjustable design can adapt to various working conditions, ensuring sufficient dehumidification while avoiding energy waste. The adjustment method is simple and convenient; just loosen the fixing bolt 22, slide the guide rod 21 to the appropriate position, and then tighten it. No parts need to be replaced, making it highly versatile. The sliding roller 48 can convert the sliding friction between the arc-shaped block 19 and the contact block 17 into rolling friction, reducing frictional resistance, minimizing component wear, and extending service life.

[0037] In this embodiment, the outside of the rotating plate 24 is provided with an abutment ring 27, and the outside of the abutment ring 27 is connected to multiple sets of first ball bearings 30. The outside of the movable frame 37 is fixedly connected to a sleeve 28, and a sleeve rod 29 is slidably connected in the sleeve 28. One end of the sleeve rod 29 is fixedly connected to the abutment ring 27, and a spring 50 is connected between the sleeve rod 29 and the sleeve 28.

[0038] In the above technical solution, the cooperation between the contact ring 27 and the first ball bearing 30 provides axial support for the rotating plate 24, while converting the sliding friction between the rotating plate 24 and the contact ring 27 into rolling friction, reducing frictional resistance and ensuring smooth rotation of the rotating plate 24. The sleeve 28, the sleeve rod 29, and the spring 50 form a reset mechanism, providing a stable reset force for the rotating plate 24. When the arc-shaped block 19 disengages from the contact block 17, the elastic force of the spring 50 pushes the sleeve rod 29 and the contact ring 27 outward, thereby pushing the rotating plate 24 to reset, closing the opening of the fixed cylinder 11, and reducing the loss of hot air. The elastic force of the spring 50 is moderate, ensuring that the rotating plate 24 resets quickly without affecting the normal opening of the rotating plate 24. Multiple sets of evenly distributed sleeves 28 and sleeve rods 29 can ensure that the contact ring 27 is subjected to uniform force, preventing the rotating plate 24 from tilting or jamming. This reset structure requires no additional power and automatically resets using the spring force of 50. It is simple, reliable, stable in operation, and has low maintenance costs, providing a reliable guarantee for the stable realization of the intermittent dehumidification function.

[0039] In this embodiment, multiple sets of buffer blocks 43 are fixedly connected to the outside of the scraper 42, and a through hole 14 is provided at one end of the roller 2. A rectangular rod 44 is fixedly connected to the outside of the scraper 42, and an insertion hole 46 is provided in the rectangular rod 44. A side frame 47 is fixedly connected to the outside of the base 1, and a pin 45 is provided through the side frame 47. A through hole is provided at the position of the rectangular rod 44 on the outside of the side frame 47, and the rectangular rod 44 passes through the through hole.

[0040] In the above technical solution, the scraper 42 is made of wear-resistant material, with its edges conforming to the inner wall of the drum 2, which can thoroughly scrape off the material adhering to the inner wall of the drum 2, resulting in clean discharge without residue. The buffer block 43 is made of elastic material, which can buffer the collision between the scraper 42 and the inner wall of the drum 2, preventing scratches on the inner wall of the drum 2, while reducing operating noise and extending the service life of the scraper 42 and the drum 2. The cooperation between the rectangular rod 44 and the pin 45 can limit and fix the scraper 42 during the drying process, preventing the scraper 42 from moving axially when the rotating shaft 31 rotates, ensuring the stability of the drying process. When discharge is required, simply pull out the pin 45 to release the limitation on the scraper 42, allowing the scraper 42 to move synchronously with the moving frame 37 for discharge.

[0041] The usage method of this embodiment is as follows: When in use, open the side door 13, put the material to be dried into the drum 2 through the feed inlet, then close the drum 2 and fix the side door 13 on the feed inlet; In the initial state, under the elastic force of the spring 50, the abutment ring 27 abuts against the outside of the rotating plate 24, applying the abutment force to the outside of the rotating plate 24, and the rotating roller 25 outside the rotating plate 24 abuts against the outside of the fixed cylinder 11; the rectangular rod 44 passes through the through hole 14 and the side frame 47, and at the same time the pin 45 is inserted into the insertion hole 46 of the rectangular rod 44, limiting and fixing the scraper 42; The output end of the hot air box is connected to the air inlet pipe 15 through a pipe to deliver hot air into the drum 2. The first motor 5 and the second motor 38 are started to work. The first motor 5 drives the gear 6 to rotate. The gear 6 meshes with the gear ring 18, thereby driving the drum 2 to rotate and realize the tumbling and drying of the material. The second motor 38 drives the rotating shaft 31 to rotate, and the rotating shaft 31 synchronously drives the rotating plate 24 to rotate. During the rotation of the rotating shaft 31, the stirring blade 32 will further turn the material to make it evenly dried. During the rotation of the rotating plate 24, the arc-shaped block 19 intermittently abuts against the abutting block 17. After being abutted, the rotating plate 24 slides outward, and the sliding sleeve 35 slides outward with the cooperation of the second ball 34 and the arc-shaped groove 33, thereby further opening the opening outside the fixed cylinder 11 and realizing the discharge of humid air (since the rotating roller 25 abuts against the outside of the fixed cylinder 11 in the initial state, there is a certain gap between the rotating plate 24 and the fixed cylinder 11, which can also discharge humid air), thus improving the discharge efficiency of humid air. After drying is completed, turn off the first motor 5 and the second motor 38, pull out the pin 45, start the third motor 39 to drive the threaded rod 40 to rotate, and under the action of the limit rod 41 and the nut block, the moving frame 37 moves outward. The moving frame 37 drives the rotating shaft 31 and the scraper 42 to slide outward synchronously. The scraper 42 can scrape out the material in the drum 2 synchronously and then discharge it through the discharge port 4.

[0042] In summary, in this embodiment, the rotation of the stirring blade 32 can improve the drying efficiency of the material, while the movement of the scraper 42 can quickly and completely discharge the material. In addition, the intermittent opening of the rotating plate 24 can further improve the discharge efficiency of humid air.
