Description

Technical Field

[0001] The present invention relates to the technical field of dehumidification, and in particular to a workshop air purification dehumidifier. Background Art

[0002] In modern industrial production, the humidity and cleanliness of workshop air have a significant impact on product quality, equipment life, and worker health. This is especially true in industries such as mechanical processing, electronics manufacturing, and food and medicine. High humidity environments can easily lead to equipment corrosion and affect product precision and quality. At the same time, suspended water vapor particles can easily combine with impurities to form pollution, reducing production accuracy and even causing electrical failures.

[0003] Existing technologies generally use dehumidification and purification equipment, which uses the negative pressure generated by the fan to draw in the workshop air for dehumidification and purification and then discharge it. However, when the humidity in the workshop increases, in order to improve the purification effect of the workshop air, the existing technology can only passively increase the fan power or use a high-power fan. This not only requires manual adjustment of the fan power, which places high demands on the fan, but also increases energy loss.

[0020] 2. The blades capture a portion of gaseous moisture in advance to reduce the power of the subsequent condenser. The blades drive the captured liquid to continuously pump it into the interior and the gas humidity is determined by liquid level detection. When the humidity of the purified gas is high, the liquid enters the liquid pipe at a faster rate than the discharge rate, causing the liquid level in the liquid pipe to slowly rise. The float drives the switch group, which in turn drives the gear ring to rotate through the motor to adjust the flow diameter of the groove surrounded by the adjustment block. The rotation and contraction of the adjustment rod and the tensioning rod, as well as the clamping of the clamping roller, achieve adaptive adjustment changes in the transition area while ensuring the strength and sealing of the transition area.

The surface of the drainage groove 312 has multiple groups of channels connected to the liquid passage 302.

[0051] The working process of this workshop air purification dehumidifier is as follows:

[0052] When purifying and dehumidifying the workshop, the air inlet 104 is set at one end facing the interior of the workshop. First, by starting the fan 102, the gas in the workshop is sucked into the ventilation pipe 103 through the air inlet 104, and then filtered and dehumidified by the filtering and condensing device set in the middle section of the ventilation pipe 103. The gas inside the workshop is further discharged through the fan 102 and can be discharged to the outside through an external pipeline or discharged into the internal circulation.

[0053] In the process of absorbing, purifying and dehumidifying the air inside the workshop, the gas enters through the air inlet 104, passes through the through groove surrounded by the regulating block 203 with a diameter smaller than the air inlet 104, hereinafter referred to as the through groove, and further enters the ventilator 103 with a diameter larger than the through groove, so that the air inlet 104 and the ventilator 103 form a venturi pipe with a contracted entrance and then gradually expanded, wherein the air inlet 104 is the entrance of the venturi pipe, the through groove is the throat, and the ventilator 103 is the subsequent diffusion section. According to the Bernoulli equation and the continuity equation, it can be concluded that the gas When the flow flows from the air inlet 104 to the through-groove, the cross-sectional area decreases and the flow rate increases. Under the premise of maintaining energy conservation, the static pressure at the inlet also decreases synchronously. Compared with the traditional ordinary straight pipe right-angle inlet, the suction has a greater impact on the turbulent loss at the inlet, the static pressure increase is limited, and the suction is limited. The Venturi contraction inlet at the air inlet 104 can accelerate the airflow by contraction, and the Bernoulli effect is used to convert kinetic energy into negative pressure energy. The high-speed and low-pressure area at the throat significantly increases the suction at the air inlet 104 entrance, thereby improving the efficiency of absorbing and purifying impurities such as water vapor suspended inside the workshop.

[0054] Furthermore, the fan 102 is driven so that the gas enters from the air inlet 104 and is discharged through the fan 102. The gas flow inside the vent pipe 103 can generate a driving force to drive the blade 301 to rotate, and then drive the ring gear 2 300 to rotate as a whole. When the blade 301 rotates, it can contact and capture the water vapor in the gas in the area it passes through. After the suspended water vapor comes into contact with the blade 301, it is gathered and drained into the drainage groove 312 through the grille on the surface of the blade 301. At the same time, the rotation of the ring gear 2 300 can drive the gear 2 304 to accelerate the rotation through the meshing transmission. When the gear 2 304 rotates, it drives the cam 305 to rotate. When the cam 305 rotates Under the reset action of the spring between the piston block 306 and the vent pipe 103, the piston block 306 can be periodically pushed to reciprocate in the vertical direction, so that the piston block 306 periodically transmits pressure to the gap formed between the piston block 306 and the vent pipe 103. When the piston block 306 moves down, the negative pressure between the top of the piston block 306 and the vent pipe 103 is sucked into the gas-liquid mixture inside the liquid collecting tank 303 through the vent pipe 103. When the piston block 306 moves up, the gas-liquid mixture can be pumped into the liquid pipe 307 through the one-way pipe 314 by pressurization. In this process, due to the action of the piston block 306, negative pressure can be continuously generated, so Suction is continuously generated by the one-way pipe 1 313, so that the negative pressure inside the liquid collecting tank 303 is generated, and then the liquid droplets gathered in the drainage tank 312 are continuously sucked into the liquid collecting tank 303 through the grooves on the surface of the drainage tank 312 through the liquid through pipe 302, and finally discharged into the liquid pipe 307. A part of the gaseous moisture can be captured in advance by the blade 301, thereby reducing the power of the subsequent condenser, thereby improving the start and stop cycle of the compressor in the dehumidification condensation system and extending the time, reducing the overall power consumption, and the captured liquid can be pumped into the liquid pipe 307 through the one-way pipe 2 314, and can be accumulated in the liquid pipe 307. If the humidity in the intake air is low, the amount of liquid pre-captured by the blade 301 will be reduced. The amount of liquid discharged into the liquid pipe 307 in the same time period is relatively small. After the liquid gathers and enters the liquid pipe 307, it is slowly discharged through the small-diameter lower discharge pipe 310. If the intake humidity is high, more liquid is captured, and the amount of liquid entering the liquid pipe 307 subsequently increases significantly. Since the diameter of the lower discharge pipe 310 is small, the liquid flow rate per unit time entering the liquid pipe 307 is greater than the liquid flow rate per unit time discharged from the lower discharge pipe 310, so that the liquid level in the liquid pipe 307 slowly rises until the liquid level drives the float 309 to float up, and the switch group 308 is started by the pull rope control, so that the motor 105 drives the gear 106 to start.

[0055] Furthermore, the gear 106 starts to drive the gear ring 1 201 to rotate. When the gear ring 1 201 rotates, the drive ring 208 drives the adjustment block 203 to rotate along the axis of the gear ring 1 201. When the adjustment block 203 rotates, it will be affected by the limited cooperation between the sliding shaft 216 and the slide groove 1 204 and the sliding shaft 3 217 and the slide groove 209. With reference to the existing iris mechanical structure technology, the flow diameter surrounded by multiple groups of adjustment blocks 203 becomes smaller, and during the rotation process of the adjustment block 203, the key grooves between the two adjacent groups of adjustment blocks 203 slide together, so that the two adjacent groups of adjustment blocks 203 fit together, reducing the gap and improving the airtight effect. Further, the adjustment block 203 moves During the movement, the displacement generated by the rotation of the adjustment block 203 is decomposed by the cooperation between the sliding shaft 1 215 and the sliding groove 3 210, and is decomposed into one group sliding inside the sliding groove 3 210 through the sliding shaft 1 215, and the other group drives the slider 1 205 to move along the radial direction of the fixed ring 200 through the sliding shaft 1 215, and the adjustment block 203 based on the radial movement of the gear ring 1 201 is transmitted to the slider 1 205. When the slider 1 205 moves, the connection between the adjustment rod 206 and the vent pipe 103 is used as the rotation point, which drives the adjustment rod 206 to rotate, and further drives the adjustment frame 212 to move synchronously. When the adjustment frame 212 moves, it can pull and drive the adjustment cloth 202 to move synchronously, and then drive the tensioner 201 to rotate. The tightening rod 211 and the second slider 207 move synchronously. Specifically, the adjusting rod 206 and the tensioning rod 211 are rotated based on the connecting shaft on the vent pipe 103 and are synchronously contracted by the corresponding sleeve design and internal spring. At the same time, the elastic design of the second slider 207 provides a support effect for the tensioning rod 211 to ensure that the adjusting cloth 202 is tensioned. The tensioning rod 211 and the adjusting rod 206 adapt to the change in the diameter difference between the adjusting block 203 and the vent pipe 103 after the diameter of the adjusting block 203 is adjusted through the groove by contraction and rotation, so that after the adjusting block 203 contracts through the groove, the transition part of the connection between the adjusting block 203 and the vent pipe 103 changes accordingly, and when the adjusting rod 206 rotates After that, when the spacing changes after the adjustment skeleton 212 rotates synchronously, the rotation and movement of the clamping roller 214 inside the fixed bin 213 and the elastic force of the spring between the fixed bin 213 and the clamping roller 214 make the two adjacent groups of clamping rollers 214 remain extended to clamp the adjustment cloth 202, reducing the gap between adjacent clamping rollers 214 and improving air tightness. When the adjustment block 203 is adjusted through the groove diameter, the rotation of the adjustment rod 206 can meet the synchronous change of the angle of the transition area support member and meet the working intensity. The rotation and tensioning of the tensioning rod 211 and the elastic clamping cooperation of the slide groove 204 ensure the airtight effect of the overall operation after the adjustment block 203 transition groove is adjusted.

[0056] It should be noted that the switch group 308 adopts an electronic touch switch, preferably using strain gauge tension sensor technology, which can be triggered when the float 309 pulls the rope, starting the motor 105 to rotate and adjust the diameter of the adjustment block 203 through the slot to a preset value, and after the accumulated liquid is discharged from the lower pipe 310 and the tension is lost, the switch group 308 is reset to control the motor 105 to start the reverse and adjust the adjustment block 203 through the slot diameter back to the initial position and then close it. Moreover, through the change of the slot diameter of the adjustment block 203, when the humidity is high, by reducing the throat diameter, the throat flow rate and static pressure difference suction are increased, and the capture efficiency of the suspended moisture with large gravity is improved. When resetting, by adjusting the throat diameter to increase, the system pressure loss can be reduced, the wind energy loss is reduced, the air volume and ventilation efficiency are increased, which is suitable for the ventilation effect of the overall environment under normal humidity, and realizes the automatic adjustment of the ventilation and dehumidification mode according to the humidity of the workshop, to ensure the efficient purification and dehumidification effect of the workshop air.
