Technical Field

[0001] The invention relates to a steam type material multi-tube drying device, in particular to a steam type material multi-tube drying device and a drying method thereof, belonging to the technical field of drying machines. Background Art

[0002] The tube bundle dryer is an indirect heating contact dryer that can dry in both co-current and counter-current modes. It is one of the most widely used and advanced dryers in most countries. It uses the principles of heat conduction and heat radiation to transfer heat from steam to the material to be dried on the other side through the wall of the heat exchange tube. The material is stirred and pushed by the shovel on the tube to move from the feed end to the discharge end and discharged through the discharge port. The vaporized water is discharged by the fan or naturally, thus completing the drying process.

[0003] However, the existing tube bundle dryer has a complex internal structure and is difficult to maintain. Once a pipe is damaged, it is difficult to repair. In addition, the existing tube bundle dryer has dense internal pipes, so it is difficult to handle high-viscosity materials and is prone to blockage.

[0004] Therefore, it is urgent to improve to solve the above-mentioned problems. Summary of the invention

Through the arrangement of a drying mechanism, the internal space is large, the maintenance of the tube bundle is simple and convenient, and the replacement and maintenance of the steam heating tube is easy, simple and fast. A plurality of steam heating tubes are arranged inside a drying cylinder. The drying equipment is based on heat conduction and is connected to hot air convection as an auxiliary method. The thermal efficiency is high. A plurality of shoveling plates are also arranged near the steam heating tube in the drying cylinder to form a combination of the steam heating tube and the shoveling plate. The material is repeatedly shoveled and thrown down to form a material curtain in the cross section of the dryer. The material is evenly dispersed and continuously sprinkled on the heating tube bundle to transfer heat and improve the drying efficiency. A chain lock is arranged on the steam heating tube to prevent the material from adhering to the inner wall of the drying cylinder, thereby broadening the scope of use.

A plurality of steam heating tubes 10 are arranged inside the drying cylinder 4. The drying equipment is based on heat conduction and connected to hot air convection as an auxiliary, and has high thermal efficiency. A plurality of shoveling plates 11 are also arranged 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 shoveled 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 to transfer heat and improve 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.

[0022] In this embodiment, Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a plurality of flip and crushing plates 13 are movably installed inside the feed pipe 5, a plurality of first motors 14 connected to the flip and crushing plates 13 are fixedly installed on the surface of the feed pipe 5, two adjacent flip and 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, one side of the transmission gear ring 15 is meshingly connected with a transmission gear 16, one side of the transmission gear 16 is fixedly installed with a transmission shaft 17, one side of the transmission shaft 17 is fixedly installed with a second motor 18, the support mechanism 7 includes a support fixing ring 19 fixedly installed on the drying cylinder 4, and the bottom of the drying cylinder 4 is provided with an auxiliary support wheel 20 that fits with the support fixing ring 19.

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 to maintain its stability.

[0024] In this embodiment, Figure 1-Figure 8 As shown, a drying method of a steam-type material multi-tube drying device comprises the following steps: Step 1: Put the material to be dried into the drying cylinder 4 from the feed pipe 5, start the first motor 14 to drive the flip crushing plate 13 to rotate in the feed pipe 5, and break up the material to prevent it from accumulating inside the feed pipe 5; 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, the material is picked up and thrown down in cooperation with the shovel 11. Then, the steam or other heating medium is connected to the steam heating pipe 10 through the steam conveying pipe 8, and the steam heating pipe 10 conducts heat conduction to dry the material inside; Step 3: While the drying cylinder 4 rotates, the chain lock 21 provided on the steam heating pipe 10 shakes under the action of the rotation force. The chain lock 21 shakes on the steam heating pipe 10 to collide with its surface, thereby cleaning the materials sticking to the surface of the steam heating pipe 10; Step 4: The dried material is finally discharged from the discharge port at the bottom of the second support seat 2 under the flipping and pushing of the drying cylinder 4 and the lifting plate 11, and the water vapor generated during drying is discharged outward through the water vapor discharge pipe 12 at the top of the second support seat 2.

[0025] In this embodiment, if Figure 1-Figure 8 As shown, the working process of a steam-type material multi-tube drying device and a drying method thereof provided in this embodiment is as follows: 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; 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, the material is picked up and thrown down in cooperation with the shovel 11. Then, the steam or other heating medium is connected to the steam heating pipe 10 through the steam conveying pipe 8, and the steam heating pipe 10 conducts heat conduction to dry the material inside; Step 3: While the drying cylinder 4 rotates, the chain lock 21 provided on the steam heating pipe 10 shakes under the action of the rotation force, and the chain lock 21 collides with the surface of the steam heating pipe 10 to clean the materials sticking to the surface of the steam heating pipe 10; Step 4: The dried material is finally discharged from the discharge port at the bottom of the second support seat 2 under the flipping and pushing of the drying cylinder 4 and the lifting plate 11.

[0026] In summary, in this embodiment, according to a steam-type material multi-tube drying equipment and a drying method thereof of this embodiment, by turning over the crushing plate 13 and 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 arrangement 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 arrangement of the support fixing ring 19 and the auxiliary support wheel 20 can support the drying cylinder 4 during its rotation to maintain its stability. By winding the chain lock 21 around the steam heating tube 10, the chain lock 21 can fully rotate the steam when it shakes. The surface of the heating pipe 10 is collided to avoid the effect of missing the lifting treatment. 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 overturning and crushing plate 13 when the chain lock 21 shakes, and then the overturning and crushing plate 13 is cleaned. Through the setting 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, and prevent harmful substances in the water vapor from floating outside and affecting the environment. Through the setting 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, so that the filter box 22 is removed from the water vapor discharge pipe 12 for cleaning, and the setting of the pull rod 28 is convenient for pulling the block 26, which is easier to disassemble.
