[0002] Explosion-proof dehumidifiers are a type of explosion-proof electrical appliance, mainly used in flammable and explosive environments such as petroleum, chemical, military, oil depots, and offshore oil platforms for air dehumidification, dehumidification, and drying. During dehumidification, it is necessary to prevent the possibility of explosion of flammable gases, dust, liquids, and mixed gases caused by the circuit. The manufacturing process requirements are higher than those of ordinary household dehumidifiers.

[0003] A search revealed a Chinese patent publication number, CN220103286U, which provides an explosion-proof dehumidifier, relating to the field of dehumidifier technology. This utility model includes a shell, with a dust removal device at the front end of the shell. The dust removal device includes an air inlet, a connecting port, a first round hole, a connecting block, a second round hole, a round rod, a pushing block, a dustproof frame, a first dustproof net, and a second dustproof net. The air inlet has several rows of air inlets arranged in an array, and a rectangular opening is provided on the rear side of the air inlet. This utility model is an explosion-proof dehumidifier, and the dust removal device is easy and quick to replace.

[0004] Although the aforementioned patent allows for the replacement of the dust removal device, the aforementioned explosion-proof dehumidifier still has the following problems: Since the device uses round rods on both sides of the air inlet structure, the filter plate can be released by pulling the round rods up and down. However, this requires separate unlocking operations, and the disassembly steps are cumbersome, resulting in a long time for disassembling the filter plate. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of explosion-proof dehumidifier with a convenient filter plate disassembly.

[0006] This utility model is achieved through the following technical solution: A novel explosion-proof dehumidifier includes a device body, an air inlet slot on the device body, an air inlet door inside the air inlet slot, an installation slot on one side of the air inlet door, a positioning slot on the inner wall of the installation slot, an installation frame rotatably connected inside the installation slot, a first groove on the top and bottom of the installation frame, a first sealing strip inside the first groove, sealing grooves on both the left and right sides of the installation frame, each sealing groove also containing a first sealing strip, a second groove communicating with the inside of the first groove on the top of the installation frame, a third sealing strip inside the second groove, a second sealing strip on the top of both the first and third sealing strips, the second sealing strips being inclined, a power slot inside the air inlet door, and a power adjustment device inside the power slot.

The transmission rod also has teeth on the side near the fixed rod. A gear is rotatably connected inside the power groove. The gear is located between the fixed rod and the transmission rod. The gear meshes with the fixed rod and the fixed frame through its teeth.

[0008] Furthermore, a spring is fixedly connected between the fixing rod and the fixing frame.

[0009] Furthermore, a sliding groove extending to the outside of the mounting frame is provided inside the mounting frame, and a filter plate is slidably connected inside the sliding groove.

[0010] Furthermore, two positioning rods are fixedly connected to the top of the mounting frame. The positioning rods are slidably connected to the inside of the positioning grooves. The inside of the positioning rods is provided with a fixing groove extending to the outside of the positioning rods. The fixing rods and fixing brackets are respectively inserted into the inside of the fixing grooves on the two positioning rods.

[0011] Furthermore, a rotating rod extending to the outside of the air inlet is fixedly connected to one side of the gear.

[0020] Example 1 like Figure 1-5 As shown, a novel explosion-proof dehumidifier includes a device body 1, which performs drying treatment. The device body 1 is an existing structure and will not be described in detail here. The device body 1 is explosion-proof due to its own materials. An air inlet slot 2 is provided on the device body 1 to allow air to enter. An air inlet door 3 is provided inside the air inlet slot 2. The air inlet door 3 is an existing structure and will not be described in detail here. A mounting groove 4 is provided on one side of the air inlet door 3. Two symmetrical positioning grooves 5 are provided on the inner wall of the mounting groove 4. A mounting frame 6 is rotatably connected inside the mounting groove 4. The top and bottom of the mounting frame 6 are provided with first grooves 10. A first sealing strip 11 is provided inside the first grooves 10. Sealing grooves 26 are provided on both the left and right sides of the mounting frame 6. A first sealing strip 11 is also provided inside the sealing groove 26. The first sealing strip 11 can improve the sealing performance of the mounting frame 6. A second groove 13 communicating with the inside of the first groove 10 is provided on the top of the mounting frame 6. A third sealing strip 14 is provided inside the second groove 13. A second sealing strip 12 is provided on the top of both the first sealing strip 11 and the third sealing strip 14. The second sealing strip 12 is inclined. The inclination of the second sealing strip 12 can improve the sealing performance of the mounting frame 6 to a certain extent. A power groove 15 is provided inside the air inlet door 3. A power adjustment device is provided inside the power groove 15.

[0021] The power adjustment device includes a fixed rod 17, which is slidably connected to the inside of the power groove 15. The fixed rod 17 is provided with some teeth. A fixed frame 19 is slidably connected inside the power groove 15. The cross-section of the fixed frame 19 is "L-shaped". A transmission rod 18 is fixedly connected to one side of the fixed frame 19. The side of the transmission rod 18 near the fixed rod 17 is also provided with teeth. A gear 16 is rotatably connected inside the power groove 15. The gear 16 is located between the fixed rod 17 and the transmission rod 18. The gear 16 is meshed with the fixed rod 17 and the fixed frame 19 through its teeth. A spring 27 is fixedly connected between the fixed rod 17 and the fixed frame 19. By moving the fixed rod 17 and the fixed frame 19 relative to each other or in opposite directions, the spring 27 can be compressed and reset.

[0022] The mounting frame 6 has multiple sliding grooves 7 extending to the outside of the mounting frame 6. A filter plate 8 is slidably connected inside the sliding groove 7. The filter plate 8 is provided with mesh holes, and can filter the outside air through the filter plate 8.

[0023] The top of the mounting frame 6 is fixedly connected to two symmetrical positioning rods 9. The positioning rods 9 are slidably connected to the inside of the positioning groove 5. The inside of the positioning rod 9 is provided with a fixing groove 20 extending to the outside of the positioning rod 9. The fixing rod 17 and the fixing bracket 19 are respectively inserted into the inside of the fixing groove 20 on the two positioning rods 9. By inserting the fixing rod 17 and the fixing bracket 19 into the inside of the fixing groove 20, the mounting frame 6 can be fixed.

[0024] A rotating rod 21 extending to the outside of the air inlet door 3 is fixedly connected to one side of the gear 16. A limiting groove 22 is provided at the end of the rotating rod 21 away from the gear 16. A moving rod 24 is slidably connected inside the limiting groove 22. The moving rod 24 has a "T" shaped cross section. A handle 25 is fixedly connected to the end of the moving rod 24 away from the limiting groove 22. By rotating the handle 25, the handle 25 can drive the rotating rod 21 to rotate, and the rotating rod 21 drives the gear 16 to rotate.

[0025] The operator rotates handle 25, which drives the moving rod 24 to rotate. The moving rod 24, through contact with the inner wall of the limiting groove 22, drives the rotating rod 21 to rotate. The rotating rod 21 drives the gear 16 to rotate. The gear 16, through meshing with the fixed rod 17 and the transmission rod 18, drives the fixed rod 17 and the fixed frame 19 to move relative to each other, compressing the spring 27. Both the fixed rod 17 and the fixed frame 19 slide out of the fixed groove 20. Then, the operator rotates the mounting frame 6 to rotate it out of the mounting groove 4, allowing the filter plate 8 to be moved. Disassembly is performed by sliding the fixing rod 17 and fixing bracket 19 out of the fixing groove 20, allowing the 8 filter plates to be removed. By setting the fixing rod 17 and fixing bracket 19, the mounting frame 6 can form a bidirectional synchronous clamping and fixing method when locking and releasing, which significantly improves the fixing strength of the mounting frame 6 and the reliability of the overall seal. It effectively reduces the problems of repetitive operation, misalignment, and unilateral force caused by disassembling from both sides one by one. It allows the staff to complete the loosening with only one action, saving time and reducing the error rate, and improving the smoothness of the disassembly and assembly process.

[0026] A tension spring 23 is fixedly connected to the end of the moving rod 24 away from the handle 25. The end of the tension spring 23 away from the moving rod 24 is fixedly connected to the inner wall of the limiting groove 22. The tension spring 23 can be stretched and reset by moving the moving rod 24.

[0027] A rotating groove 29 is provided on one side of the air inlet door 3. A stop bar 28 is fixedly connected to the inner wall of the rotating groove 29. The handle 25 is rotatably connected to the inside of the rotating groove 29. The stop bar 28 can limit the handle 25. The stop bar 28 can limit the device to be fixed more stably.

[0028] When the operator pulls handle 25, handle 25 causes moving rod 24 to slide, tension spring 23 is stretched, and handle 25 rises above stop bar 28, releasing the stop bar 28's restriction on handle 25, allowing handle 25 to rotate. After rotation, handle 25 is released, tension spring 23 returns to its original position, and moving rod 24 and handle 25 return to their original positions. Handle 25 then falls below stop bar 28, and stop bar 28 re-restricts handle 25. By restricting handle 25 with stop bar 28, the risk of handle 25 rotating due to collision, vibration, or accidental contact during equipment operation is reduced. This eliminates the risk of fixed rod 17 and fixed frame 19 being accidentally loosened, ensuring that mounting frame 6 remains reliably locked, and significantly improving the dehumidifier's anti-loosening, anti-leakage, and explosion-proof safety.

[0029] This embodiment provides a novel explosion-proof dehumidifier. When in use, if the filter plate 8 needs to be disassembled or replaced, the operator first pulls the handle 25, causing the moving rod 24 to slide outward along the limiting groove 22. The tension spring 23 is stretched, causing the handle 25 to move upward above the stop bar 28, thereby releasing the limiting protection of the handle 25 by the stop bar 28. Then, the operator continues to rotate the handle 25, which drives the moving rod 24 to rotate. The moving rod 24 contacts the inner wall of the limiting groove 22, driving the rotating rod 21 to rotate synchronously. The rotating rod 21 drives the gear 16 to start rotating. The gear 16 drives the fixed rod 17 and the fixed frame 19 to move simultaneously in opposite directions, pushing them to disengage from the fixed groove 20. At this time, the spring 27 is compressed and stores energy. When the fixed rod 17 and the fixed frame 19 are completely removed from the fixed groove 20, the mounting frame 6 is released from its fixed position. The mounting frame 6 is rotated and slides out of the mounting groove 4, allowing the operator to clean or replace the filter plate 8. After replacement, rotate the mounting frame 6 back into the mounting slot 4, so that the positioning rod 9 slides back into the positioning slot 5 to achieve initial positioning. Rotate the handle 25 in the opposite direction, and align the fixing rod 17 and the fixing bracket 19 with the fixing slot 20 and reinsert them, so that the spring 27 is reset, achieving automatic locking without manual alignment. This also allows the multi-layer sealing structure, such as the first sealing strip 11, the second sealing strip 12, and the third sealing strip 14, to fit together synchronously, restoring the sealing effect and ensuring that the air inlet door 3 does not leak or loosen during operation.

[0030] After returning to its original position, the handle 25 is released. Under the action of the tension spring 23, the handle 25 automatically falls back to below the stop bar 28 and is once again limited by the stop bar 28. This prevents the handle 25 from rotating accidentally due to vibration or accidental contact during equipment operation, thereby protecting the fixed structure from being accidentally loosened. This ensures that the mounting frame 6 always maintains a safe and stable sealed and locked state, ensuring that the dehumidifier operates reliably in an explosion-proof environment.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
