Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, specifically to a filter structure for a vacuum drying oven. Background Technology

[0002] As is well known, vacuum drying ovens are designed specifically for drying heat-sensitive, easily decomposed, and easily oxidized substances. During operation, they can maintain a certain degree of vacuum within the working chamber and can be filled with inert gas. In particular, they can quickly dry some complex items. They use an intelligent digital temperature controller for temperature setting, display, and control. During the rapid drying process, vacuum drying ovens often require a filtration device to prevent dust from entering the interior of the vacuum drying oven during the processing of the items.

[0003] However, most existing vacuum drying ovens use bolts to fix the filter devices on the drying oven. This means that when cleaning or replacing the filter devices, operators need to carry the corresponding disassembly and assembly tools. Without these tools, operators cannot disassemble or assemble the filter devices, which increases their workload and affects the efficiency of cleaning the filter devices. Summary of the Invention

Detailed Implementation

[0026] 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.

[0027] See Figures 1-8 A filtration structure for a vacuum drying oven includes a chamber body 1, which is a vacuum drying oven. The top of the chamber body 1 has two sets of air inlets 5. The inner walls of the air inlets 5 are welded with two sets of baffles 11. A movable plate 8 is slidably connected inside the air inlets 5, and the baffles 11 are located at the bottom of the movable plate 8. A filter screen 7 is installed inside the movable plate 8 to block dust. A slot 10 is opened on the outer side of the movable plate 8. Two sets of handles 9 are welded to the top of the movable plate 8. A movable groove 6 is opened inside the chamber body 1. Two sets of mounting components 2 are installed on the inner wall of the movable groove 6. A drive component 3 is installed on the top of the chamber body 1, and one side of the drive component 3 is slidably connected inside the movable groove 6.

[0028] First, refer to Figures 1 to 5 In this embodiment, the mounting assembly 2 includes a horizontal plate 204 slidably connected within the movable groove 6 and a central shaft 210 welded to the inner wall of the movable groove 6. Two sets of parallel mounting plates 211 are welded to one side of the horizontal plate 204. A fixed shaft 212 is bolted between the two sets of mounting plates 211. A top plate 213 is rotatably connected to the outside of the fixed shaft 212. Two sets of discs are bolted to the outside of the fixed shaft 212, and the two sets of discs are located at the top and bottom of the top plate 213, respectively. The top plate 213 is inclined, and a movable column 207 is rotatably connected to the side of the top plate 213 away from the fixed shaft 212. A swing plate 209 is rotatably connected to the outer side of the central shaft 210. The swing plate 209 is inclined and the inclination direction of the swing plate 209 is opposite to that of the top plate 213. A groove 208 is provided inside the swing plate 209. One side of the drive assembly 3 is slidably disposed in the groove 208. The side of the swing plate 209 away from the central shaft 210 is rotatably connected to the outer side of the moving column 207. Two sets of connecting plates 202 are provided on the side of the horizontal plate 204 away from the mounting plate 211. The side of the two sets of connecting plates 202 away from the horizontal plate 204 is welded to the locking block 201. The locking block 201 and the locking groove 10 are parallel.

[0029] Then, refer to Figures 3 to 5 In this embodiment, the inner wall of the movable groove 6 is bolted with two sets of balance bars 214, and the movable column 207 is slidably disposed on the outside of the balance bars 214. Thus, the movement of the movable column 207 can be restricted by the balance bars 214 to prevent the movable column 207 from being misaligned during movement.

[0030] Secondly, see Figures 3 to 5 In this embodiment, two sets of springs 203 are provided on the side of the horizontal plate 204 away from the mounting plate 211. The end of the spring 203 away from the horizontal plate 204 is fixedly installed on the inner wall of the movable groove 6. Thus, when the horizontal plate 204 is pushed and displaced, the spring 203 will be squeezed by the horizontal plate 204. When the horizontal plate 204 is no longer pushed, the spring 203 will drive the locking block 201 to move back by bouncing the horizontal plate 204, so that the locking block 201 quickly returns to the initial position and disengages from the locking groove 10, ensuring the reuse of the device.

[0031] Again, see Figures 3 to 5 In this embodiment, four limiting rods 206 are bolted to the inner wall of the movable groove 6. The horizontal plate 204 is slidably connected to the outside of the two sets of limiting rods 206. Thus, on the one hand, the limiting rods 206 maintain the balance of the horizontal plate 204 during movement, preventing the horizontal plate 204 from becoming unbalanced and swaying during movement, and ensuring the normal displacement of the horizontal plate 204. On the other hand, the limiting rods 206 restrict the direction of the horizontal plate 204, preventing the device from failing due to misalignment of the horizontal plate 204, and ensuring the normal use of the device.

[0032] In addition, see Figures 3 to 5 In this embodiment, a buffer pad 205 is provided on the outer side of the limiting rod 206. The buffer pad 205 is a rubber buffer pad. The buffer pad 205 is located on the side of the horizontal plate 204 away from the spring 203. Thus, the buffer pad 205 can block the horizontal plate 204 and prevent the horizontal plate 204 from detaching from the limiting rod 206.

[0033] When the swing plate 209 is pushed, it will swing around the central axis 210. At this time, the side of the swing plate 209 connected to the moving column 207 will push the moving column 207 to move laterally. The lateral movement of the moving column 207 will push one side of the top plate 213 to swing. At this time, the top plate 213 will swing around the fixed axis 212 and push the fixed axis 212. When the fixed axis 212 is pushed, it will drive the horizontal plate 204 to move by pushing the mounting plate 211. The movement of the horizontal plate 204 will drive the connecting plate 202 to move the locking block 201, so that the locking block 201 can lock the movable plate 8 and the filter screen 7 by locking into the slot 10.

[0034] Finally, see Figure 1 , Figure 3 , Figure 6 and Figure 7In this embodiment, the drive assembly 3 includes a rotary motor 301 disposed on one side of the housing 1 and a top roller 305 slidably disposed in the slide groove 208. The rotary motor 301 is a bidirectional motor, and its output end can rotate forward or backward. The output end of the rotary motor 301 is keyed to a threaded tube 306, and a sleeve 302 is screwed onto the outer side of the threaded tube 306. When the threaded tube 306 rotates, it will drive the sleeve 302 screwed onto its outer side to move linearly. The operator can control the sleeve 302 by controlling the rotation direction of the output end of the rotary motor 301. The sleeve 302 has a movable plate 303 on one side, and the movable plate 303 is slidably disposed in the movable groove 6. The movable plate 303 is provided with four support plates 304 on the side near the swing plate 209. The two sets of support plates 304 are fixedly disposed on the side away from the movable plate 303 and the outer side of the top roller 305. The housing 1 is provided with a protective cover 4 on the side near the rotary motor 301. The protective cover 4 is located on the outside of the rotary motor 301 and the threaded pipe 306, so that the protective cover 4 can protect the rotary motor 301 and the threaded pipe 306.

[0035] After the rotary motor 301 is turned on, its output end will drive the threaded tube 306 to rotate. The rotation of the threaded tube 306 will drive the sleeve 302 to move linearly. When the sleeve 302 moves, it will drive the moving plate 303 to move. When the moving plate 303 moves, it will drive the support plate 304 to move. When the support plate 304 moves, it will drive the top roller 305 to move in the slide groove 208 and push the swing plate 209.

[0036] The filter structure of this vacuum drying oven, with the cooperation between the locking block 201 and the locking slot 10, allows the movable plate 8 to be secured by the locking block 201 after it is engaged in the locking slot 10, thus ensuring that the filter screen 7 is stably installed in the air inlet 5. At the same time, when the locking block 201 is disengaged from the locking slot 10, the movable plate 8 will no longer be secured, allowing the operator to easily remove the filter screen 7 for cleaning or replacement. This eliminates the need for the operator to carry the necessary tools to disassemble and assemble the filter structure, avoiding situations where disassembly and assembly are impossible without the necessary tools.

[0037] Working principle:

[0038] In use, the filter structure of this vacuum drying oven is first placed in the desired position. Then, the filter screen 7 is installed. The specific operation is as follows: the movable plate 8 is inserted into the air inlet 5. When the movable plate 8 is blocked by the baffle 11 and cannot move further down, the slot 10 and the locking block 201 are parallel. Then, the rotary motor 301 is turned on so that its output end drives the threaded tube 306 to rotate. The rotation of the threaded tube 306 will drive the sleeve 302 to move linearly. When the sleeve 302 moves, it will drive the movable plate 303 to move. When the movable plate 303 moves, it will drive the support plate 304 to move. When the support plate 304 moves, it will drive the top roller 305 to move in the sliding groove 208 and push and swing. When the swing plate 209 is pushed, it will swing around the central axis 210. At this time, the side of the swing plate 209 connected to the moving column 207 will push the moving column 207 to move laterally. The lateral movement of the moving column 207 will push one side of the top plate 213 to swing. At this time, the top plate 213 will swing around the fixed shaft 212 and push the fixed shaft 212. When the fixed shaft 212 is pushed, it will drive the horizontal plate 204 to move by pushing the mounting plate 211. The movement of the horizontal plate 204 will drive the connecting plate 202 to move the locking block 201, so that the locking block 201 can lock the movable plate 8 and the filter screen 7 by locking into the slot 10, thus completing the installation of the filter screen 7.

[0039] Finally, the filter screen 7 is disassembled for cleaning. The specific operation is as follows: the output end of the rotating motor 301 is reversed to move the sleeve 302 back. At this time, the top roller 305 will push the swing plate 209 back, and the spring 203 will drive the locking block 201 back by moving the horizontal plate 204 back, so that the locking block 201 quickly returns to the initial position and disengages from the slot 10. At this time, the movable plate 8 is no longer locked, and the operator can take out the movable plate 8 and the filter screen 7 for cleaning.
