Description

Technical Field

[0001] This utility model relates to the field of environmental conditioning and safety protection equipment technology, and in particular to a front-discharge industrial explosion-proof dehumidifier. Background Technology

[0002] In industrial production and warehousing environments, humidity control is crucial for ensuring normal equipment operation, stable product quality, and safe production. Especially in flammable and explosive environments, such as chemical plants, oil and gas facilities, or dusty areas, dehumidifiers not only need high-efficiency dehumidification performance but also must meet explosion-proof safety requirements. Existing industrial dehumidifiers typically employ side-discharge or top-discharge designs. These structures have limitations in terms of spatial layout and airflow organization, particularly in scenarios with limited installation space or requiring forward airflow, making them unsuitable for practical needs. Furthermore, traditional dehumidifiers often rely on simple electrical isolation or enclosure protection for explosion-proof design, lacking systematic explosion-proof optimization and posing certain safety hazards. Simultaneously, existing equipment still needs improvement in terms of energy efficiency, ease of operation, and adaptability to complex operating conditions. Therefore, developing a dehumidifier with a front-discharge design, excellent explosion-proof performance, and adaptability to industrial environments has become an urgent technical challenge. This will not only improve space utilization and dehumidification efficiency but also further enhance equipment safety and reliability, providing a superior humidity control solution for industrial production.

[0003] The purpose of this utility model is to provide a front-discharge industrial explosion-proof dehumidifier that solves the problems mentioned in the background art.

[0004] This utility model is implemented as follows: a front-discharge industrial explosion-proof dehumidifier includes a housing, an air outlet on the front side of the housing, and an internal partition that divides the housing into upper and lower chambers. The upper chamber contains a condenser and an evaporator, and the lower chamber contains a compressor and a fan. The front-discharge industrial explosion-proof dehumidifier also includes:

[0005] The air deflector is hinged to the inner wall of the housing at both ends and is located behind the air outlet. The bottom of the air deflector is equipped with a toothed rack.

[0006] The gear meshes with the rack. The central shaft of the gear passes through the partition and is rotatably connected to the partition through a bearing. One end of the central shaft is connected to an adjustment knob, which is located on the outside of the housing.

[0007] The inner wall of the housing is provided with a guide groove that allows the rack to slide.

[0008] Optionally, the top of the housing is provided with an air inlet, a filter screen is provided at the air inlet, and buckles are symmetrically provided on both sides of the filter screen. The buckles are fixed in place with the slots on the inner wall of the housing, and the bottom of the buckles is provided with an elastic piece.

[0009] Optionally, it also includes an explosion-proof mechanism disposed inside the housing. The explosion-proof mechanism includes: two sets of slide rails symmetrically disposed on the inner wall of the housing, each set of slide rails having a slider slidably connected therein, the inner side of the slider being movably connected to the outer wall of the protective cover through a connecting rod, and one end of the slider being provided with a first spring, one end of the first spring being fixedly connected to the inner wall of the slide rail.

[0010] The protective cover is located on the outside of the compressor. A pressure relief valve is installed on the top of the protective cover. One end of the pressure relief valve passes through the housing and is connected to the outside.

[0011] Optionally, the pressure relief valve has a sealing ball inside, a second spring below the sealing ball, one end of the second spring being fixedly connected to the inner wall of the pressure relief valve, and an exhaust hole at the top of the pressure relief valve.

[0023] This utility model provides a front-discharge industrial explosion-proof dehumidifier, the structure of which and its operating principle can be described in the attached document. Figure 1 To be continued Figure 3 Detailed Description. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and markings. This utility model's front-discharge industrial explosion-proof dehumidifier includes a housing 1, with an air outlet 2 on the front side. The interior of the housing 1 is divided into upper and lower chambers by a partition 3. The upper chamber houses a condenser 4 and an evaporator 5, while the lower chamber houses a compressor 6 and a fan 7. Furthermore, the device includes a guide vane 8, gears 10, a rack 9, and an adjustment knob 12, which together constitute a guide vane adjustment mechanism to allow for flexible adjustment of the air outlet direction. Simultaneously, the device is equipped with an explosion-proof mechanism to enhance operational safety.

[0024] As attached Figure 1As shown, the overall structure of the casing 1 is clearly visible. The air outlet 2 on its front side is located directly in front of the equipment, facilitating direct air exhaust from the front. A partition 3 divides the interior of the casing 1 into upper and lower chambers. The upper chamber primarily houses the condenser 4 and evaporator 5, while the lower chamber houses the compressor 6 and fan 7. This layered design not only optimizes the space utilization of the equipment but also effectively avoids mutual interference of heat during heat exchange. The condenser 4 and evaporator 5, as core components, are responsible for condensing moisture in the air, while the compressor 6 and fan 7 are responsible for driving the refrigerant circulation and airflow, respectively. In actual use, air enters the equipment through the air inlet 14 at the top of the casing 1. After preliminary purification by the filter 15, it passes through the condenser 4 and evaporator 5 sequentially, and is finally driven by the fan 7 and exhausted from the air outlet 2.

[0025] To meet the needs of different usage scenarios, this utility model features a specially designed deflector adjustment mechanism. (See attached diagram) Figure 2 As shown, the air deflector 8 is located behind the air outlet 2, and its two ends are connected to the inner wall of the housing 1 by hinges, allowing it to rotate around the hinge point. A rack 9 is located at the bottom of the air deflector 8, meshing with a gear 10. The central shaft 11 of the gear 10 passes through the partition 3 and is rotatably connected to the partition 3 via a bearing. One end of the central shaft 11 extends to the outside of the housing 1 and is connected to the adjustment knob 12. When the user rotates the adjustment knob 12, the gear 10 rotates accordingly, causing the rack 9 to slide along the guide groove 13. Since the rack 9 is fixedly connected to the air deflector 8, the movement of the rack 9 changes the angle of the air deflector 8, thereby adjusting the air outlet direction. This design allows the user to flexibly adjust the air outlet angle according to actual needs. For example, when concentrated airflow is needed, the air deflector 8 can be adjusted to a smaller angle, while when wide-angle airflow is needed, the air deflector 8 can be adjusted to a larger angle. In addition, the meshing joint of gear 10 and rack 9 is coated with a lubricating coating made of polytetrafluoroethylene, which not only reduces frictional resistance but also extends the service life of the components.

[0026] To further enhance the safety and reliability of the equipment, this utility model also incorporates an explosion-proof mechanism. (See attached diagram) Figure 3As shown, the explosion-proof mechanism mainly includes a slide rail 18, a slider 19, a protective cover 21, and a pressure relief valve 22. The slide rails 18 are symmetrically arranged on the inner wall of the housing 1. Each set of slide rails 18 has a slider 19 slidably connected within it. The inner side of the slider 19 is movably connected to the outer wall of the protective cover 21 via a connecting rod 20. One end of the slider 19 is equipped with a first spring, and one end of the first spring is fixedly connected to the inner wall of the slide rail 18. Under normal operating conditions, the protective cover 21 covers the outside of the compressor 6, providing isolation and protection. Once the compressor 6 malfunctions, causing an increase in internal pressure, the protective cover 21 will move outward under pressure. At this time, the slider 19 slides along the slide rail 18, and the first spring is compressed. This design can quickly form an isolation zone in the event of a hazard, preventing the accident from spreading. Simultaneously, a pressure relief valve 22 is located on the top of the protective cover 21, with one end penetrating the housing 1 and communicating with the outside. The pressure relief valve 22 has a sealing ball 23 inside, and a second spring 24 is located below the sealing ball 23. One end of the second spring 24 is fixedly connected to the inner wall of the pressure relief valve 22. When the internal pressure exceeds the set value, the sealing ball 23 will be pushed up, and the gas will be discharged through the vent 25, thereby releasing the excessive pressure. This dual protection mechanism ensures the safety of the equipment under extreme conditions.

[0027] The design of filter 15 also reflects the user-friendly features of this utility model. (See attached image) Figure 1 As shown, the filter screen 15 is located at the air inlet 14 at the top of the housing 1 to filter impurities in the air entering the equipment. The filter screen 15 has symmetrically arranged clips 16 on both sides, which engage with grooves on the inner wall of the housing 1 for fixation. The bottom of the clips 16 has an elastic piece 17 made of stainless steel with a bending angle of 30° to 45°. This design makes the removal and installation of the filter screen 15 more convenient; users only need to gently press the clips 16 to complete the operation, greatly improving maintenance efficiency. Furthermore, the elasticity of the elastic piece 17 ensures a tight connection between the clips 16 and the grooves, preventing the filter screen 15 from loosening or falling off during operation.

[0028] The surface of the guide plate 8 is provided with several guide vanes 26, each with an arc-shaped cross-section and evenly distributed along the length of the guide plate 8. This design not only guides the airflow to flow more smoothly but also reduces turbulence on the surface of the guide plate 8, thereby reducing noise. Meanwhile, the inner wall of the protective cover 21 is provided with sound-absorbing cotton 27, which is 10mm to 20mm thick, further absorbing noise generated during equipment operation and making the equipment quieter in industrial environments. Furthermore, the outer side of the adjustment knob 12 is provided with anti-slip textures, with a depth of 0.5mm to 1mm. This design improves user comfort and accuracy during operation.

[0029] In practical applications, this front-discharge industrial explosion-proof dehumidifier can be widely used in chemical plants, pharmaceutical factories, warehouses, and other places requiring strict humidity and safety control. For example, in a chemical plant, the equipment can adjust the angle of the guide vane 8 to concentrate the dried air to a specific area, thereby quickly reducing the humidity in that area. Simultaneously, the explosion-proof mechanism effectively addresses compressor malfunctions, ensuring the equipment's safety in high-risk environments. Furthermore, the easy-to-remove filter 15 allows users to regularly clean or replace it, maintaining the equipment's efficient operation.

[0030] In summary, this invention achieves flexible adjustment of the air outlet direction through the guide vane adjustment mechanism, enhances the safety and reliability of the equipment through the explosion-proof mechanism, and improves maintenance efficiency through the convenient design of the filter screen 15. Meanwhile, the application of the guide vane 26 and sound-absorbing cotton 27 further optimizes the equipment's performance. These designs together constitute a highly efficient, safe, and easy-to-maintain front-discharge industrial explosion-proof dehumidifier, capable of meeting the needs of various industrial scenarios.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
