Description

Technical Field

[0001] This utility model relates to the field of dehumidification equipment technology, and in particular to an explosion-proof dehumidifier. Background Technology

[0002] Explosion-proof dehumidifiers are a type of explosion-proof electrical appliance, mainly used in flammable and explosive environments such as petroleum, chemical, 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.

[0003] Explosion-proof dehumidifiers mainly consist of a motor, compressor, condenser, evaporator, and heat exchanger. Their working principle is as follows: when air passes through the compressor, it is compressed into a high-temperature, high-pressure gas with a temperature close to the dew point. This gas then enters the condenser, condenses into a liquid, and is discharged from the condenser, mixing with the indoor air to form dry air. If there is water, the condensate will evaporate into water vapor in the evaporator.

[0004] In existing explosion-proof dehumidifiers, the air entering the dehumidifier needs to be filtered. After long-term use, the filter screen will become clogged. The clogged filter screen needs to be disassembled and cleaned. Moreover, the dust adhering to the filter screen is prone to being stirred up. This can easily cause dust pollution during electrical use and increase the risk of dust explosion.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0020] See Figure 1 , Figure 2 and Figure 3This utility model provides an explosion-proof dehumidifier, which includes a housing 2, an air inlet on one side, and a filter element 12 for filtering dust inside the air inlet. The filter element 12 can be a dust filter screen to ensure that the air entering the housing 2 can be filtered, preventing dust from entering the dehumidifier and protecting the internal components. A base 1 is provided at the bottom of the housing 2 to fix it in a predetermined position. The water tank 10 located at the bottom of the housing 2 allows wastewater generated by the dehumidifier to be directly discharged into the water tank 10, facilitating the subsequent cleaning and rinsing of the filter element 12 using the water in the water tank 10. The top of the air inlet, located at the rear end of the filter element 12, has a nozzle 8 angled towards the back of the filter element 12. The nozzle 8 is connected to the water tank 10, and a driving component for forced water flow is provided between the nozzle 8 and the connecting pipe 9 of the water tank 10. The driving component can be a water pump, ensuring that the water inside the water tank 10 is pumped into the nozzle 8 to rinse the filter element 12, thus realizing the recycling of water.

[0021] In one embodiment, to ensure that the wastewater generated during the rinsing process is directed into the interior of the water storage tank 10, a filter screen 3 is provided on the outside of the air inlet. The filter screen 3 is used to filter large impurities outside the housing 2. A drain outlet is provided between the filter screen 3 and the filter element 12 to ensure that the generated wastewater is discharged from between them. The drain outlet is located at the bottom of the air inlet and is connected to the water storage tank 10 through a drain pipe 11. The generated wastewater is directed into the interior of the water storage tank 10 through the drain pipe 11. A guide groove 13 is provided at the bottom of the drain outlet between the filter screen 3 and the filter element 12. The drain outlet is connected to the bottom of the guide groove 13. The guide groove 13 guides the mixture of water and dust into the interior of the water storage tank 10.

[0022] In addition, to ensure the dehumidification effect of the air, an air outlet 4 is provided on the back side of the housing 2. A dehumidification module 14 is provided between the air outlet 4 and the air inlet. The dehumidification module 14 dehumidifies the incoming air, thereby ensuring the dryness of the air discharged from the air outlet 4. In order to drain the water inside the dehumidification module 14, the drain outlet of the dehumidification module 14 is connected to the water storage tank 10. The air supply port of the dehumidification module is connected to the air inlet through an air supply pipe 7. The air supply pipe 7 slopes upward from the air inlet to the dehumidification module 14 to prevent water sprayed by the nozzle 8 from entering the interior of the dehumidification module 14 and damaging the dehumidification module 14 when the nozzle 8 cleans the filter element 12. The dehumidification module 14 is connected to the water storage tank 10 through a drain pipe 6. The drain pipe 6 guides the water inside the dehumidification module 14 into the interior of the guide channel 13, thereby ensuring that the water inside the dehumidification module 14 can be discharged from the housing 2.

[0023] Further, see Figure 3 and Figure 4In order to ensure the control of the water volume inside the water storage tank 10, a sewage outlet 5 is provided at the bottom of the water storage tank 10. Inside the water storage tank 10, there is a control component 16 for controlling the opening and closing of the sewage outlet 5. When the water volume inside the water storage tank 10 reaches a predetermined value, the control component 16 controls the sewage outlet 5 to open. When the water volume inside the water storage tank 10 is lower than the predetermined value, the control component 16 controls the sewage outlet 5 to close. This ensures that the water volume inside the water storage tank 10 is controlled under the action of the control component 16, preventing the water volume inside the water storage tank 10 from being too high or too low.

[0024] In one exemplary implementation, combined with Figure 5 The control component 16 includes: A baffle 164 is slidably connected to the inside of the sewage outlet 5. By setting the baffle 164 to block and open the sewage outlet 5, the amount of water inside the water storage tank 10 can be controlled. A vertical rod 162 is installed on the outside of the baffle 164 and fixed to the outside of the baffle 164 to ensure that the vertical rod 162 can be set perpendicular to the water surface. The vertical rod 162 is provided with an upper limit block 161 and a lower limit block 163. The amount of water is controlled by the upper limit block 161 and the lower limit block 163. A float 15 is slidably connected between the upper limit block 161 and the lower limit block 163. As the float 15 rises and falls, it controls the opening and closing of the baffle 164 to the sewage outlet 5. A sliding groove is opened on the inner side of the water storage tank 10, which corresponds to the inner side of the sewage outlet 5. The baffle 164 is slidably connected to the inside of the sliding groove, thereby controlling the opening and closing size of the sewage outlet 5.

[0025] When using, please refer to Figures 1-5 The dehumidification module 14 draws air into the housing 2 through the air inlet, removes moisture from the air, and then the moisture enters the water storage tank 10 through the drain pipe 6. After prolonged use, the filter element 12 becomes clogged. The water pump then pumps water from the water storage tank 10 into the nozzle 8, which flushes the filter element 12. The flushed water enters the drain pipe 11 through the guide channel 13 and then into the water storage tank 10. As the water level in the water storage tank 10 increases, the float 15 rises with the increase in water volume. Under the restriction of the upper limit block 161, the baffle 164 rises and moves, opening the sewage outlet 5 and allowing water to drain out. After the sewage level drops to a certain point, the baffle 164 slides downward under the action of the float 15, blocking the sewage outlet 5 and thus controlling the sewage volume.

[0026] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
