Description

Technical Field

[0001] This utility model belongs to the field of air handling equipment, and in particular relates to an industrial dehumidifier that allows the heat exchanger to be pulled out of the housing. Background Technology

[0002] An industrial dehumidifier is a device specifically designed for industrial environments, primarily used to reduce and control humidity in the air. It maintains air humidity within a suitable range by removing excess moisture to meet the dry air requirements of production, storage, or specific processes.

[0003] In traditional industrial dehumidifiers, the heat exchanger is usually fixed inside the equipment. The enclosed structure and limited maintenance space make maintenance and cleaning extremely inconvenient. Once the heat exchanger malfunctions or needs regular cleaning, it often requires disassembling a large number of parts, which is complicated, time-consuming, and seriously affects the efficiency and maintenance costs of the equipment.

[0004] Therefore, there is a particular need for industrial dehumidifiers that allow the heat exchanger to be pulled out of the enclosure to solve the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of traditional industrial dehumidifiers where the heat exchanger is fixedly installed inside the equipment, making maintenance and cleaning inconvenient and affecting equipment efficiency and maintenance costs, this utility model provides an industrial dehumidifier that allows the heat exchanger to be pulled out of the casing.

[0006] This utility model is achieved through the following technical means: an industrial dehumidifier that allows the heat exchanger to be pulled out of the housing, comprising a frame, flaps, a sliding plate, guide rails, a support frame, a heat exchanger body, a water collection tank, a compressor, a first connecting pipe, an air pump, a second connecting pipe, a flow valve, a limiting component, a fan, and a control panel. Two flaps are arranged side by side and rotatably mounted on one side of the lower part of the frame. Two guide rails are horizontally distributed and fixed to the inner bottom end of the frame in the left-right direction. The sliding plate is slidably mounted between the two guide rails. The support frame is installed on one side of the top of the sliding plate. The heat exchanger body is installed inside the support frame. The water collection tank is slidably placed on the support frame. Inside, and below the heat exchanger body, the compressor is installed on the other side of the top of the sliding plate. A flow valve is installed at each end of the compressor. The air pump is installed on the other side of the top of the sliding plate and is located between the heat exchanger body and the compressor. Connecting pipe one is installed between one of the flow valves and the heat exchanger body, and connecting pipe two is installed between the other flow valve and the air pump. Two fans are installed side by side in the upper part of the frame. The control panel is installed on the upper side of the frame. The heat exchanger body, compressor, air pump, flow valves and fans are all electrically connected to the control panel. The limit component is located in the lower part of the frame.

[0007] As a preferred technical solution of this utility model, the limiting component includes a locking plate, a base plate, guide rods, return springs, and an electromagnet. The locking plate is slidably disposed at the lower part of the frame, with its upper part extending into the interior of the frame and closely fitting the sliding plate. The locking plate is made of low carbon steel. The base plate is fixedly connected to the lower part of the frame, and two symmetrically distributed guide rods are fixedly connected to it. One end of the guide rod is fixedly connected to the locking plate. A return spring is sleeved on the outside of each guide rod, and both ends of each return spring are fixedly connected to the locking plate and the base plate, respectively. The electromagnet is mounted on the base plate and electrically connected to the control panel. The locking plate is located above the electromagnet.

[0008] As a preferred technical solution of this utility model, it also includes a limiting frame, a mounting plate, a liquid level detector, a controller, and an alarm. The limiting frame is installed at the lower part of the support frame, and its bottom end is at the same horizontal height as the top end of the water collection tank. Two mounting plates are installed side by side inside the limiting frame. The liquid level detector is installed at the bottom end of one mounting plate, and the controller is installed at the bottom end of the other mounting plate. The alarm is installed on one side of the limiting frame. Both the liquid level detector and the alarm are electrically connected to the controller.

[0009] As a preferred technical solution of this utility model, it also includes a filter plate, which is fixedly connected to the other side of the lower part of the frame.

[0010] As a preferred technical solution of this utility model, it also includes a magnetic plate, which is installed on the lower side of the support frame, and the water collection tank is located in front of the magnetic plate, with a magnetic block disposed inside the side of the water collection tank near the magnetic plate.

[0011] As a preferred embodiment of this utility model, a handle is fitted on the side of the water collection tank away from the magnetic plate.

[0012] Beneficial effects: 1. Through the cooperative design of the sliding plate and the guide rail, the heat exchanger body can be smoothly pulled out of the frame along with the sliding plate. At the same time, the limiting component adopts the linkage structure of electromagnet and locking plate, which realizes automatic unlocking and reset under the operation of the control panel. The operation is convenient, safe and reliable. The staff can perform maintenance or cleaning of the heat exchanger body at any time without disassembling the whole machine, which significantly shortens the maintenance time and reduces the maintenance cost caused by downtime.

[0013] 2. The intelligent monitoring system, consisting of a liquid level detector, controller, and alarm, can detect changes in the water level of condensate inside the water collection tank in real time. When the water level reaches the set upper limit, the controller immediately triggers the alarm to issue an audible and visual alarm, promptly reminding staff to drain the water. This effectively prevents equipment failure or environmental pollution caused by water overflow and ensures the long-term stable operation of the dehumidifier. Attached Figure Description

[0023] Example: An industrial dehumidifier where the heat exchanger can be pulled out of the casing, such as... Figures 1-7As shown, the system includes a frame 1, a flap 2, a filter plate 3, a sliding plate 4, guide rails 5, a support frame 6, a heat exchanger body 7, a water collection tank 8, a magnetic plate 801, a compressor 9, a connecting pipe 10, an air pump 11, a connecting pipe 2 12, a flow valve 13, a limit assembly, a fan 19, and a control panel 20. Two flaps 2 are arranged side-by-side and rotatably mounted on the lower front side of the frame 1. Each flap 2 is equipped with a handle. The filter plate 3 is fixedly connected to the lower rear side of the frame 1. Two guide rails 5 are horizontally distributed and fixedly connected to the inner bottom of the frame 1. The sliding plate 4 is slidably positioned between the two guide rails 5. The support frame 6 is bolted to the top left side of the sliding plate 4. The heat exchanger body 7 is bolted inside the support frame 6. The water collection tank 8 is slidably placed inside the support frame 6 and located below the heat exchanger body 7, responsible for collecting condensate generated during heat exchange. The magnetic plate 801 is bolted to the lower rear side of the support frame 6. The water collection tank 8 is located on the magnetic plate 801. A magnetic block is installed inside the water collection tank 8 near the rear side of the magnetic plate 801. The magnetic block and the magnetic plate 801 are magnetically attracted to lock the position of the water collection tank 8 on the support frame 6. A handle is installed on the front side of the water collection tank 8 away from the magnetic plate 801. The compressor 9 is bolted to the top right side of the sliding plate 4. A flow valve 13 is bolted to both the upper and lower ends of the compressor 9. The air pump 11 is bolted to the top right side of the sliding plate 4 and is located between the heat exchanger body 7 and the compressor 9. Connecting pipe 10 is bolted to the lower flow valve 13 and the heat exchanger body 7. Connecting pipe 212 is bolted to the upper flow valve 13 and the air pump 11. Two fans 19 are bolted to the upper inner part of the frame 1. The control panel 20 is bolted to the upper left side of the frame 1. The heat exchanger body 7, compressor 9, air pump 11, flow valve 13 and fans 19 are all electrically connected to the control panel 20. The limiting component is located at the lower part of the frame 1.

[0024] like Figure 3 , Figure 4 and Figure 5 As shown, the limiting assembly includes a locking plate 14, a base plate 15, guide rods 16, a return spring 17, and an electromagnet 18. The locking plate 14 is slidably disposed at the lower part of the frame 1, with its upper part extending into the interior of the frame 1 and tightly fitting the sliding plate 4, thereby limiting the position of the sliding plate 4 within the frame 1. The locking plate 14 is made of low-carbon steel and has good magnetic and mechanical strength. The base plate 15 is fixedly connected to the lower part of the frame 1, and two symmetrically distributed guide rods 16 are fixedly connected to it. The upper end of the guide rods 16 is fixedly connected to the locking plate 14. A return spring 17 is sleeved on the outside of each guide rod 16. The upper and lower ends of each return spring 17 are fixedly connected to the locking plate 14 and the base plate 15, respectively, to provide a reset force for the locking plate 14. The electromagnet 18 is bolted to the base plate 15 and electrically connected to the control panel 20. The locking plate 14 is located above the electromagnet 18.

[0025] like Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, it also includes a limiting frame 21, a mounting plate 22, a liquid level detector 23, a controller 24, and an alarm 25. The limiting frame 21 is bolted to the lower part of the support frame 6, and its bottom end is at the same level as the top end of the water collection tank 8. It can limit the position of the water collection tank 8 within the support frame 6 and provide positioning guidance for the placement of the water collection tank 8. The two mounting plates 22 are bolted to the inside of the limiting frame 21. The bottom end of the front mounting plate 22 is bolted to the liquid level detector 23, and the bottom end of the rear mounting plate 22 is bolted to the controller 24. The alarm 25 is bolted to the front of the limiting frame 21. Both the liquid level detector 23 and the alarm 25 are electrically connected to the controller 24.

[0026] When maintenance or cleaning of the heat exchanger body 7 is required, the electromagnet 18 is energized via the control panel 20. The electromagnet 18 generates magnetism, attracting the low-carbon steel locking plate 14 to move downward. Guided by the guide rod 16, the locking plate 14 overcomes the elastic force of the return spring 17 and slides downward along the lower part of the frame 1 until the upper part of the locking plate 14 leaves the inside of the frame 1 and is no longer tightly attached to the sliding plate 4, thus releasing the restriction on the position of the sliding plate 4 within the frame 1. At this time, the sliding plate 4 is pulled out from the inside of the frame 1. As the sliding plate 4 moves, the support frame 6 and the heat exchanger body 7 installed inside the support frame 6 are also pulled out of the housing for maintenance or cleaning operations.

[0027] After completing the relevant operations of the heat exchanger body 7, push the sliding plate 4 back into the frame 1 along the guide rail 5 to the appropriate position. Then, control the electromagnet 18 to be de-energized through the control panel 20. The electromagnet 18 loses its magnetism, and the locking plate 14 slides upward along the guide rod 16 under the elastic force of the return spring 17 until the upper part of the locking plate 14 extends back into the frame 1 and fits tightly against the sliding plate 4, restoring the restriction on the position of the sliding plate 4 in the frame 1, and ensuring the stability of the heat exchanger body 7 during operation.
