[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-5This utility model provides a narrow wedge-shaped inner heating plate double cone vacuum dryer, including a base plate 9 and a double cone vacuum dryer body 1 mounted on the top of the base plate 9. The double cone vacuum dryer body 1 includes a steam pipe, a vacuum pipe, a drive mechanism, a tank 23, a top cover 22 set on the top of the tank 23, and a steam cavity 21 opened in the circumferential wall of the tank 23. A fixing frame 5 is fixed to the top of the base plate 9 by bolts. A through groove is opened on one side of the fixing frame 5 at the top position. A feed pipe 4 inclined from bottom to top is fixed in the through groove by bolts. A connecting shaft is rotatably connected between the inner wall of the top and the inner wall of the feed pipe 4 by bearings. A spiral blade 10 is welded to the outer circumference of the connecting shaft and contacts the inner wall of the feed pipe 4. A servo motor that drives the connecting shaft to rotate along the axis is fixed to the outer wall of the top of the feed pipe 4 by bolts. A spiral blade 10 inclined from top to bottom and in contact with the inner wall of the feed pipe 4 is fixed to the outer circumference of the feed pipe 4 at the top position by bolts. The first connecting pipe 3 is connected to the pipe 4. The other end of the first connecting pipe 3 is fixed with a guide pipe 2 connected to the first connecting pipe 3 by bolts. The guide pipe 2 is located at the top of the feed inlet of the tank 23. The inner wall of the guide pipe 2 is provided with an extension component. The outer circumference of the conveying pipe 4 and near the bottom end is provided with a feeding component to facilitate the feeding of material into the conveying pipe 4. When the servo motor is started, the servo motor drives the connecting shaft to rotate along the axis. The connecting shaft drives the spiral blade 10 to rotate in the conveying pipe 4, thereby conveying the material from the bottom to the top of the conveying pipe 4. The material enters the guide pipe 2 through the first connecting pipe 3 and then enters the tank 23. This greatly facilitates the feeding of the double cone vacuum dryer, solves the problem of operators having to frequently raise their arms for manual feeding, greatly reduces the workload of operators, and avoids the possibility of operators being burned by the high temperature gas discharged around the feeding port, thus improving safety.

[0024] In this embodiment, the extension assembly includes a sliding tube 12 slidably connected to the inner wall of the guide tube 2. A first fixing plate 14 is fixed to the outer wall of the sliding tube 12 by bolts. A second fixing plate 15 is fixed to the outer wall of the guide tube 2 and located on top of the first fixing plate 14 by bolts. A first self-locking cylinder 11, which drives the first fixing plate 14 to move up and down, is fixed to the top of the second fixing plate 15 by bolts. The diameter of the sliding tube 12 is slightly smaller than the diameter of the feed inlet of the tank 23. A sealing ring 13 is bonded to the outer circumference of the sliding tube 12, and the diameter of the sealing ring 13 is larger than the diameter of the feed inlet of the tank 23. When the first self-locking cylinder 11 is activated, the piston rod of the first self-locking cylinder 11 extends out, pushing the first fixing plate 14 and the sliding tube 12 downward. The part of the sliding tube 12 extending out of the guide tube 2 increases the total length of the guide tube 2. The sliding tube 12 is inserted into the feed inlet of the tank 23. At the same time, the sealing ring 13 can fit tightly against the edge of the feed inlet of the tank 23 to prevent material from splashing out from the gap.

[0025] In this embodiment, the feeding assembly includes a second connecting pipe 8 that is fixed to the outer circumference of the conveying pipe 4 by bolts and located at the bottom. The second connecting pipe 8 is inclined from bottom to top. A support frame 7 is fixed to the top of the bottom plate 9 and located at the edge by bolts. A funnel 6 whose bottom is connected to the second connecting pipe 8 is fixed to the top of the support frame 7 by bolts. The material can be accurately added into the conveying pipe 4 through the funnel 6. The top opening of the funnel 6 is large, which makes it easy to pour the material in.

[0026] In this embodiment, a fixing block 18 is bolted to the top of the tank 23. A groove 19 is provided on the top of the fixing block 18. A second self-locking cylinder 16 is bolted to the top of the fixing bracket 5 and to one side of the fixing block 18. One end of the piston rod of the second self-locking cylinder 16 is bolted to a protrusion 17 that inserts into the groove 19. When the second self-locking cylinder 16 is activated, the piston rod of the second self-locking cylinder 16 moves the protrusion 17 downward, so that the protrusion 17 inserts into the groove 19, thereby realizing the rapid fixing of the tank 23, avoiding shaking of the tank 23 during the feeding process, and enhancing the stability of the tank 23.

[0027] In this embodiment, multiple heat-conducting plates 20 are fixed to the outer wall of the tank 23 by bolts, and one side of the heat-conducting plate 20 passes through the inner wall of the tank 23 and is inserted into the steam cavity 21. The heat-conducting plate 20 is a narrow wedge-shaped copper plate. Steam enters the steam cavity 21 through the steam pipe. The heat of the steam is quickly transferred to the material in the tank 23 through the heat-conducting plate 20. The heat-conducting plate 20 is made of copper. Copper has excellent thermal conductivity, so it can quickly and evenly distribute heat to all corners of the tank 23. It also ensures that the material in the tank 23 is heated evenly, avoiding the problem of local overheating or uneven temperature.

[0028] It should be noted that the first self-locking cylinder, the second self-locking cylinder, and the servo motor used in this application are all prior art. Those skilled in the art can set them according to actual needs, and they will not be described in detail here.

[0029] The use of this utility model involves the following steps:

[0030] S1: First, start the second self-locking cylinder 16. The piston rod of the second self-locking cylinder 16 moves downward with the protrusion 17 so that the protrusion 17 is inserted into the groove 19. Then open the top cover 22.

[0031] S2: Then start the first self-locking cylinder 11. The piston rod of the first self-locking cylinder 11 extends and pushes the first fixed plate 14 and the sliding tube 12 downward, inserting the sliding tube 12 into the feed inlet of the tank 23. At the same time, the sealing ring 13 can fit tightly against the edge of the feed inlet of the tank 23.

[0032] S3: Then pour the material into the funnel 6. The material in the funnel 6 enters the conveying pipe 4 through the second connecting pipe 8. Then start the servo motor to drive the connecting shaft to rotate along the axis. The connecting shaft drives the spiral blade 10 to rotate in the conveying pipe 4, thereby conveying the material from the bottom to the top of the conveying pipe 4. The material enters the guide pipe 2 through the first connecting pipe 3 and then enters the tank 23.

[0033] S4: After the feeding is completed, the first self-locking cylinder 11 is started. The piston rod of the first self-locking cylinder 11 retracts, driving the first fixed plate 14 and the sliding tube 12 to move upward, so that the sliding tube 12 is disengaged from the feed port of the tank body 23.

[0034] S5: Then close the top cover 22, and then start the second self-locking cylinder 16. The piston rod of the second self-locking cylinder 16 moves upward with the protrusion 17, so that the protrusion 17 disengages from the groove 19. Then start the double cone vacuum dryer to dry the material.

[0035] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
