Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] like Figures 1-8 As shown, this embodiment provides an embodiment of a steam-type material multi-tube drying equipment and a drying method thereof.

[0030] A steam-type multi-tube drying equipment for materials comprises a first support seat 1 and a second support seat 2, a drying mechanism 3 is provided between the first support seat 1 and the second support seat 2, the drying mechanism 3 is movably mounted on a drying cylinder 4 between the first support seat 1 and the second support seat 2, a feed pipe 5 is fixedly mounted on the first support seat 1, a transmission mechanism 6 is provided on the drying cylinder 4, support mechanisms 7 mounted on the drying cylinder 4 are provided on both sides of the transmission mechanism 6, a steam delivery pipe 8 is movably mounted on both the first support seat 1 and the second support seat 2, a rotary joint 9 is installed at one end of the steam delivery pipe 8, a plurality of steam heating pipes 10 are installed between the two steam delivery pipes 8, a chain lock 21 is fixedly installed on the steam heating pipe 10, a plurality of copying plates 11 are fixedly mounted on the inner wall of the drying cylinder 4, and a top of the second support seat 2 is fixedly mounted. A water vapor discharge pipe 12 is provided, and a discharge port is provided at the bottom of the second support seat 2. Through the arrangement of the drying mechanism 3, the internal space is large, the tube bundle maintenance is simple and convenient, and the replacement and maintenance of the steam heating tube 10 is easy, simple and fast. A plurality of steam heating tubes 10 are provided inside the drying cylinder 4. The drying equipment is based on heat conduction and is assisted by hot air convection, and the thermal efficiency is high. A plurality of shoveling plates 11 are also provided near the steam heating tube 10 in the drying cylinder 4 to form a combination of the steam heating tube 10 and the shoveling plate 11. The material is repeatedly scooped up and thrown down to form a material curtain in the cross section of the dryer, which is evenly dispersed and continuously sprinkled on the heating tube bundle for heat transfer, thereby improving the drying efficiency. In addition, a chain lock 21 is provided on the steam heating tube 10 to prevent the material from adhering to the inner wall of the drying cylinder 4, thereby broadening the scope of use.

[0031] In this embodiment, a plurality of flip crushing plates 13 are movably installed inside the feed pipe 5, and a plurality of first motors 14 connected to the flip crushing plates 13 are fixedly installed on the surface of the feed pipe 5. Two adjacent flip crushing plates 13 are cross-connected in the feed pipe 5. The transmission mechanism 6 includes a transmission gear ring 15 fixedly installed on the drying cylinder 4, and a transmission gear 16 is meshedly connected to one side of the transmission gear 16. A transmission shaft 17 is fixedly installed on one side of the transmission gear 16, and a second motor 18 is fixedly installed on one side of the transmission shaft 17. The support mechanism 7 includes a support fixing ring 19 fixedly installed on the drying cylinder 4, and an auxiliary support wheel 20 is provided at the bottom of the drying cylinder 4 to fit with the support fixing ring 19. By setting the flipping crushing plate 13 and the first motor 14, the material put into the feed pipe 5 can be broken up so that it can fall smoothly into the drying cylinder 4 to prevent accumulation inside the feed pipe 5. Through the setting of the transmission gear ring 15, the transmission gear 16, the transmission shaft 17, the second motor 18, the support fixing ring 19 and the auxiliary support wheel 20, after the second motor 18 is started, the transmission gear 16 is driven to rotate through the transmission shaft 17. After the transmission gear 16 rotates, it can drive it to rotate under the action of meshing with the transmission gear ring 15, thereby driving the drying cylinder 4 to rotate and flipping the material inside it. At the same time, the setting of the support fixing ring 19 and the auxiliary support wheel 20 can support the drying cylinder 4 during its rotation and maintain its stability.

[0032] In this embodiment, the chain lock 21 is wound around the steam heating pipe 10, and the steam heating pipe 10 and the shovel 11 are surrounded inside the drying cylinder 4. A filter box 22 is fixedly installed on the top of the water vapor discharge pipe 12, and a plurality of activated carbon filters 23 are installed in sequence from top to bottom inside the filter box 22. Two fixed frames 24 are fixedly installed on the water vapor discharge pipe 12, and a spring 25 is fixedly installed inside the fixed frame 24. A card block 26 is fixedly installed at one end of the spring 25. Limit blocks 27 that engage with the card block 26 are fixedly installed on both sides of the filter box 22, and a pull rod 28 extending to the outside of the fixed frame 24 is fixedly installed on the card block 26. By winding the chain lock 21 around the steam heating pipe 10, the chain lock 21 can fully collide with the surface of the steam heating pipe 10 when it is shaken, avoiding the effect of missing the lifting process. At the same time, the steam heating pipe 10 and the shoveling plate 11 are distributed around the interior of the drying cylinder 4, which can not only make the turning and drying of the material more uniform, but also can contact the turnover crushing plate 13 when the chain lock 21 is shaken, and then the turnover crushing plate 13 is cleaned. By setting the filter box 22 and the activated carbon filter 23, the steam can be discharged when the steam is discharged. During the process, it plays the role of filtering and purifying to prevent harmful substances in the water vapor from floating outside and affecting the environment. Through the setting of the fixed frame 24, spring 25, block 26, limit block 27 and pull rod 28, the filter box 22 is installed on the top of the water vapor discharge pipe 12 by the clamping of the block 26 and the limit block 27. The clamping connection method not only plays a supporting and fixing role, but also facilitates disassembly, making it easy to remove the filter box 22 from the water vapor discharge pipe 12 for cleaning, and the setting of the pull rod 28 facilitates the pulling of the block 26, making it easier to disassemble.

[0033] In this embodiment, if Figures 1-8 As shown, the working process of a steam-type material multi-tube drying equipment and drying method provided in this embodiment is as follows:

[0034] Step 1: Feed the material to be dried from the feed pipe 5 into the drying cylinder 4, start the first motor 14 to drive the flip crushing plate 13 to rotate in the feed pipe 5, break up the material and make it fall smoothly into the drying cylinder 4;

[0035] Step 2: After the material enters the drying cylinder 4, the second motor 18 is started to drive the transmission gear 16 to rotate through the transmission shaft 17. The rotation of the transmission gear 16 drives the transmission gear ring 15 to rotate the drying cylinder 4. After the drying cylinder 4 rotates, it cooperates with the lifting plate 11 to scoop up and throw the material inside it. Then, the steam or other heating medium is connected to the steam heating pipe 10 through the steam conveying pipe 8. The steam heating pipe 10 conducts heat conduction to dry the material inside.

[0036] Step 3: As the drying cylinder 4 rotates, the chain lock 21 provided on the steam heating pipe 10 shakes under the action of the rotational force. The chain lock 21 collides with the surface of the steam heating pipe 10 and cleans the material stuck on the surface of the steam heating pipe 10.

[0037] Step 4: The dried material is finally discharged from the discharge port at the bottom of the second support base 2 under the flipping and pushing of the drying cylinder 4 and the lifting plate 11.

[0038] In summary, in this embodiment, according to a steam-type multi-tube material drying equipment and drying method thereof of this embodiment, by turning over the crushing plate 13 and the setting of the first motor 14, the material put into the feed pipe 5 can be broken up, so that it can smoothly fall into the drying cylinder 4 to prevent accumulation inside the feed pipe 5. By the setting of the transmission gear ring 15, the transmission gear 16, the transmission shaft 17, the second motor 18, the support fixing ring 19 and the auxiliary support wheel 20, after the second motor 18 is started, the transmission gear 16 is driven to rotate through the transmission shaft 17. After the transmission gear 16 rotates, it can drive it to rotate under the action of meshing with the transmission gear ring 15, thereby driving the drying cylinder 4 to rotate and turning over the material inside it. At the same time, the setting of the support fixing ring 19 and the auxiliary support wheel 20 can support the drying cylinder 4 during its rotation and maintain its stability. By wrapping the chain lock 21 around the steam heating pipe 10, the chain lock 21 can fully impact the steam when it shakes. The surface of the heating pipe 10 collides to avoid the effect of missing the lifting process. At the same time, the steam heating pipe 10 and the lifting plate 11 are distributed around the interior of the drying cylinder 4, which can not only make the turning and drying of the material more uniform, but also can contact the flip crushing plate 13 when the chain lock 21 shakes, and then the flip crushing plate 13 is cleaned. Through the arrangement of the filter box 22 and the activated carbon filter 23, it can play a filtering and purification function in the process of water vapor discharge, preventing harmful substances in the water vapor from drifting outside and affecting the environment. Through the arrangement of the fixing frame 24, the spring 25, the block 26, the limit block 27 and the pull rod 28, the filter box 22 is installed on the top of the water vapor discharge pipe 12 by the block 26 and the limit block 27. The clamping connection method not only plays a supporting and fixing role, but also facilitates disassembly, making it easy to remove the filter box 22 from the water vapor discharge pipe 12 for cleaning, and the arrangement of the pull rod 28 is convenient for pulling the block 26, which is easier to disassemble.
