Description

Technical Field

[0001] This utility model relates to the field of vacuum dryer technology, specifically a clean-type enamel double cone vacuum dryer with multiple air extraction ports. Background Technology

[0002] As is well known, a vacuum dryer is a low-temperature device that heats materials under vacuum. Vacuum dryers are used for dehydrating and drying high-value-added and heat-sensitive agricultural and sideline products, health products, food, medicinal materials, fruits and vegetables, chemical raw materials, etc. In the existing technology, the double cone vacuum dryer is a double cone-shaped rotating tank. Under vacuum conditions, steam or hot water is introduced into the jacket for heating. The heat comes into contact with the wet material through the inner wall of the tank, which can accelerate the drying speed of the material and improve the drying efficiency.

[0003] Currently, most existing clean-type enamel-lined double cone vacuum dryers have a filter structure installed at one end of the suction pipe to prevent material from entering and causing blockage. Over time, material easily adheres to the surface of the filter structure, causing blockage of the filter pores and affecting the vacuum extraction efficiency of the tank. Therefore, personnel need to disassemble and clean the filter structure regularly. However, most existing filter structures are bolted to the suction pipe, which requires operators to carry the corresponding disassembly and assembly tools. Without the tools, operators cannot disassemble and assemble the filter structure, affecting the cleaning of the filter structure. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] See Figures 1-3 A clean-type enamel double-cone vacuum dryer with multiple exhaust ports includes a body 1, which is a double-cone vacuum desiccant with two sets of exhaust ports inside. An air inlet pipe 2 is provided on the top of the body 1 and communicates with the interior of the body 1. The air inlet pipe 2 has slots 9 on both sides and communicates with the interior of the air inlet pipe 2. A fixing plate 7 is welded inside the air inlet pipe 2 and a mounting plate 8 is slidably connected inside the air inlet pipe 2. The fixing plate 7 is a hollow fixing plate and is located at the bottom of the mounting plate 8. A filter screen 6 is provided in the middle of the mounting plate 8. Two sets of mounting components 3, two sets of drive components 5, and four sets of adjustment components 4 are provided on the outside of the air inlet pipe 2.

[0027] The top of the mounting plate 8 is provided with two sets of handles 10, which allow the operator to easily pick up the mounting plate 8.

[0028] First, refer to Figure 2 , Figure 4 and Figure 5 In this embodiment, the mounting assembly 3 includes a limiting rod 303 bolted to the outside of the intake pipe 2. A movable plate 301 is slidably provided on the outside of the limiting rod 303. A locking block 308 is provided on the side of the movable plate 301 near the intake pipe 2, and the locking block 308 is engaged in the locking groove 9. When the locking block 308 is displaced, the side of the locking block 308 away from the movable plate 301 will enter the interior of the intake pipe 2. At this time, one side of the locking block 308 will abut against the mounting plate 8, so that the mounting plate 8 and the filter screen 6 are stably installed in the intake pipe 2.

[0029] Two sets of mounting tubes 307 are provided on the side of the movable plate 301 away from the card block 308. A fixed shaft 306 is provided on the outside of the two sets of mounting tubes 307. Two sets of support plates 305 are provided on the outside of the fixed shaft 306. The support plates 305 are inclined and the two sets of support plates 305 are inclined in the same direction.

[0030] Then, refer to Figures 4 to 5In this embodiment, two sets of springs 302 are provided on the side of the movable plate 301 near the air intake pipe 2. The end of the spring 302 away from the movable plate 301 is fixedly installed on the outside of the air intake pipe 2, and the spring 302 is located outside the limiting rod 303. Thus, when the movable plate 301 is pushed, the spring 302 will be squeezed. When the movable plate 301 is no longer pushed, the spring 302 will drive the locking block 308 to move back by bouncing the movable plate 301, so that the locking block 308 quickly returns to the initial position and no longer fixes the mounting plate 8.

[0031] Secondly, see Figures 4 to 5 In this embodiment, a buffer pad 304 is provided on the outer side of the limiting rod 303. The buffer pad 304 is a rubber buffer pad and is located on the side of the movable plate 301 away from the air intake pipe 2. Thus, the buffer pad 304 can block the excessive displacement of the movable plate 301, avoid the situation where the movable plate 301 disengages from the limiting rod 303 and causes the device to fail, and ensure the normal use of the device.

[0032] When the support plate 305 is pushed, it will drive the fixed shaft 306 to move the mounting tube 307. The movement of the mounting tube 307 will drive the movable plate 301 to move, thereby causing the locking block 308 to move, so that the side of the locking block 308 away from the movable plate 301 enters the intake pipe 2.

[0033] Again, see Figure 2 and Figure 6 In this embodiment, the adjustment component 4 includes a placement plate 401 disposed outside the air intake pipe 2. A balance bar 402 is welded to the bottom of the placement plate 401. A slider 403 is slidably disposed outside the balance bar 402. One side of the drive component 5 is slidably disposed outside the balance bar 402. A push plate 404 is bolted to the side of the slider 403 near the movable plate 301. The push plate 404 is inclined and is used to install the pulley 405. The push plate 404 can be replaced with other load-bearing structures.

[0034] The bottom end of the balance bar 402 is bolted with an anti-detachment block 407. The length of the anti-detachment block 407 is greater than the diameter of the balance bar 402. Thus, the anti-detachment block 407 can block the slider 403, preventing the slider 403 from detaching from the balance bar 402 and causing the device to fail.

[0035] A central shaft 406 is welded to the side of the push plate 404 away from the slider 403. A pulley 405 is rotatably mounted on the outer side of the central shaft 406, and the outer side of the pulley 405 contacts the outer side of the support plate 305.

[0036] When the slider 403 is pushed to move, the slider 403 will drive the central shaft 406 and pulley 405 to move by driving the push plate 404. When the pulley 405 moves upward, it will push the support plate 305 to move laterally.

[0037] In addition, see Figure 2 and Figure 7 In this embodiment, the drive assembly 5 includes a bearing 505 disposed on the outside of the intake pipe 2. A threaded tube 503 is disposed in the middle of the bearing 505. A sleeve 504 is screwed onto the outside of the threaded tube 503. When the threaded tube 503 rotates, it will drive the sleeve 504 to move linearly. The operator can control the direction of movement of the sleeve 504 by controlling the direction of rotation of the threaded tube 503. Two sets of top blocks 506 are disposed on the outside of the sleeve 504. The top blocks 506 are slidably disposed on the outside of the balance bar 402 and are located below the slider 403.

[0038] Finally, see Figure 2 and Figure 7 In this embodiment, two sets of protective covers 502 are provided on the outside of the air intake pipe 2. The protective covers 502 are located on the outside of the threaded pipe 503 and the sleeve 504, thereby protecting the threaded pipe 503 and the sleeve 504 and preventing damage to them.

[0039] To facilitate the rotation of the threaded tube 503, a handle 501 is provided at the top of the threaded tube 503, and the handle 501 is located outside the protective cover 502. Thus, the operator can rotate the threaded tube 503 by turning the handle 501.

[0040] When the handle 501 is turned to make the threaded tube 503 rotate, the threaded tube 503 will drive the sleeve 504 to move linearly. The movement of the sleeve 504 will drive the top block 506 to move. When the top block 506 moves upward, it will push the slider 403 to move.

[0041] This multi-port clean-type enamel double cone vacuum dryer features a movable locking block 308. When installing the filter screen 6, moving the locking block 308 secures the filter screen 6; when removing the filter screen 6, moving the locking block 308 releases it. This allows operators to install and remove the filter screen 6 without tools, increasing the efficiency of filter screen cleaning, expanding the device's applicability, and making it suitable for widespread adoption.

[0042] Working principle:

[0043] When using this multi-port clean-type enamel double-cone vacuum dryer, first place it in the desired location. Then, install the mounting plate 8 and filter screen 6. Specifically, insert the mounting plate 8 into the inlet pipe 2. When the mounting plate 8 is blocked by the fixing plate 7 and cannot move downwards, turn the handle 501 to rotate the threaded tube 503. The rotation of the threaded tube 503 will cause the sleeve 504 to move linearly. The movement of the sleeve 504 will cause the top block 506 to move. When the top block 506 moves upwards, it will push the slider 403 to move. When the slider 403 is pushed to move, the slider... 403 will drive the central shaft 406 and pulley 405 to move by driving the push plate 404. When the pulley 405 moves upward, it will push the support plate 305 to move laterally. When the support plate 305 is pushed, it will drive the mounting tube 307 to move by driving the fixed shaft 306. The movement of the mounting tube 307 will drive the movable plate 301 to move, thereby driving the locking block 308 to move. This will cause the locking block 308 to enter the intake pipe 2 from the side away from the movable plate 301. At this time, the locking block 308 will cooperate with the fixed plate 7 to lock the mounting plate 8 in the intake pipe 2, so that the mounting plate 8 and the filter screen 6 are stably installed in the intake pipe 2.

[0044] Finally, disassemble the mounting plate 8 and the filter screen 6. The specific operation is as follows: reverse the handle 501 to reverse the threaded tube 503 and drive the sleeve 504 back. The back movement of the sleeve 504 will cause the top block 506 to move back and no longer push the slider 403. At this time, the spring 302 will drive the locking block 308 back by springing the movable plate 301 back, so that the locking block 308 quickly returns to the initial position and no longer fixes the mounting plate 8. Then the operator can disassemble the mounting plate 8 and the filter screen 6.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
