Technical Field
[0001] This utility model belongs to the field of dehumidification and air supply technology, and specifically relates to a cleanroom air supply device with dehumidification components. Background Technology
[0002] To ensure a suitable working environment in the production workshop, fresh air needs to be supplied. However, to prevent humid air from affecting the workshop's equipment, the fresh air needs to be dehumidified. Existing dehumidification and air supply devices have the following technical problems during use: 1) They only have simple filters for dust filtration. Due to prolonged filtration, some moisture in the air is absorbed by dust particles, causing them to clump on the filter surface. Without a cleaning mechanism to clean them in time, this affects the intake air; 2) When using air circulation and condensation dehumidification technology for dehumidification, the internal evaporator only has a reciprocating circular tube. The air circulation speed inside is relatively fast, and it can only perform simple treatment. If the air humidity is high, its dehumidification effect is poor.
[0003] A search revealed that prior art CN222747431U discloses a dehumidification and air supply device for a clean laboratory, including an air supply duct. Two filters are fixedly connected inside the air supply duct. Rotary shafts are equidistantly rotatably connected inside the air supply duct. A first mounting groove is formed inside the air supply duct, and a worm gear is rotatably connected inside the first mounting groove. Adjusting vanes are fixedly connected to the outer side of each rotating shaft. One end of each rotating shaft extends into the first mounting groove and is fixedly connected to a worm wheel, which meshes with the worm gear. A cleaning mechanism is provided inside the air supply duct. The above technical solution utilizes the rotation of the worm gear... The angle of the regulating blades is adjusted according to the actual dehumidification and air supply requirements. The rotation of the threaded rod can drive the movement of the threaded block, thereby using the U-shaped cleaning plate to scrape off the impurities on the filter screen surface. However, the above technical solution still has the following technical problems: 1) Although the U-shaped cleaning plate can clean the impurities on the filter screen surface, it can also easily squeeze dust particles into the filter screen holes, affecting the working efficiency of the filter screen; 2) During the operation, the scraped dust particles will scatter everywhere and are easily blown onto the filter screen by the incoming air, so its cleaning effect is not good.
[0004] For example, the existing technology CN219713560U discloses an energy-saving laboratory dehumidification and air supply device, including a base plate, a dehumidification box fixedly installed at the center of the top of the base plate, and an evaporator fixedly installed at the center of one end of the dehumidification box. The above technical solution can solve the technical problem that some of the hot air in the evaporator is discharged out along the drain outlet, causing internal heat loss and continuous heating, resulting in high costs; and the technical problem that dust particles contained in the external humid and cold air are easy to adhere to the evaporator, condenser and other components. However, the above technical solution still has the following technical problems when in use: 1) Using a vibrating frame to assist the filter plate to vibrate continuously along the top of the dust collection trough can play a certain cleaning role, but if the airflow velocity is large, the vibration dust removal effect is not obvious, and the dust that falls down is easily blown straight onto the filter plate by the fresh air, resulting in poor cleaning effect; 2) The thick pipe is wound around the evaporator to facilitate intermittent heat exchange with the passing humid and cold air, but the fresh air flows quickly in the evaporator. If the humidity is high, it cannot be effectively cleaned and will be blown into the next processing mechanism, affecting the final air supply effect.
[0005] The applicant searched for patent number CN201510872488.1 and authorization announcement number CN105344173B, regarding a filter screen dust removal device, and pointed out that: existing air filter screen dust removal devices, such as... Figure 1 As shown, the device includes a dust removal motor 03 adapted to be fixedly mounted on the indoor-facing side of an air filter 01. The dust removal motor 03 has a motor shaft 02 extending out of the air filter 01 and located outdoors. A dust removal brush 04 is fixedly mounted on the motor shaft 02, with the bristles of the dust removal brush 04 in close contact with the outer surface of the air filter 01. When dust removal is required, the dust removal motor 03 is started, and the motor shaft 02 drives the brush 04 to rotate. The bristles of the brush 04 rotate and sweep the outer surface of the air filter 01, removing the adhering dust. Summary of the Invention
[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a cleanroom air supply device with a dehumidification component. By setting a dust removal mechanism in the air inlet pipe, the dust removal mechanism is protected by a protective cover and brushed repeatedly to minimize dust entering the filter pores and prevent fresh air from blowing away the dust, thereby improving dust removal efficiency. In addition, a zigzag baffle is added between the guide pipes in the evaporator to extend the air flow path in the evaporator and increase the heat exchange area, so that it can also have a good dehumidification effect for air with high humidity.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A cleanroom air supply device with dehumidification components includes an air inlet pipe, a dehumidification box, an air outlet pipe, a compressor, a dust removal mechanism, an evaporator, a condenser, a water storage tank, a water outlet pipe, and a fan. The dehumidification box is fixedly connected to the air inlet pipe and the air outlet pipe at both ends. The air inlet pipe is equipped with a dust removal mechanism, and the air outlet pipe is equipped with a fan. The dehumidification box is equipped with an evaporator and a condenser from one end of the air inlet pipe to one end of the air outlet pipe. The evaporator and the condenser are connected end to end by a pipe, and their other ends are connected to the inlet and outlet of the compressor, respectively. A water storage tank is located below the evaporator and is fixedly installed below the dehumidification box. A water outlet pipe is fixedly connected to one side of the water storage tank.
[0009] The dust removal mechanism includes a motor, a fixed bracket, a mounting frame, filters, a protective cover, a collection box, cleaning rods, brushes, a fixed rod, connecting rod I, connecting rod II, and an eccentric wheel. A fixed bracket is installed inside the air inlet pipe. A mounting frame is movably mounted on the fixed bracket, and several filters are mounted on the mounting frame. Synchronous pulleys are located at both ends of the mounting frame's rotating shaft. One end of the synchronous pulley is connected to the synchronous pulley at the motor output end via a synchronous belt, and the other end is connected to the synchronous pulley at one end of the eccentric wheel's central rotating shaft via a synchronous belt. The eccentric wheel's central rotating shaft is movably mounted on the protective cover, which is fixedly mounted on the inner wall of the air inlet pipe. One end of the eccentric wheel's eccentric shaft is movably connected to one end of connecting rod II, and the other end of connecting rod II is movably connected to connecting rod I. Several cleaning rods are movably mounted on connecting rod I, and each cleaning rod has several brushes. The other end of each cleaning rod is movably mounted on a fixed rod, which is mounted on the protective cover. The bottom of the protective cover has an opening on one side, and a collection box is movably mounted thereon.
[0010] A 10mm-20mm gap is left between the protective cover and the filter screen to ensure that it does not come into contact with the filter screen to prevent damage, while also preventing dust from overflowing.
[0011] The collection box has a handle on one side, which makes it easy for staff to pull the collection box out.
[0012] The evaporator is equipped with several guide tubes, and heat-conducting plates are installed between the guide tubes. The heat-conducting plates are installed in a zigzag shape between the guide tubes and have several fins.
[0013] The heat-conducting plate and fins are made of copper, which has good thermal conductivity and can further enhance the heat exchange efficiency with the air, ensuring the dehumidification effect.
[0014] The advantages of this utility model compared with the prior art are as follows:
[0015] 1) After air enters the intake pipe, it passes through the filter screen to filter dust particles. During the filtration process, the motor drives the mounting bracket to rotate. At the same time, through the transmission of several synchronous pulleys and belts, the eccentric wheel drives several connecting rods to swing back and forth. This causes the sweeping rod to drive the bristles to sweep and clean the surface of the filter screen back and forth. Due to the setting of the protective cover, dust particles can be prevented from scattering. The rotation of the filter screen and the back and forth swing of the sweeping rod are combined to further improve the cleaning effect, ensure dust removal efficiency, extend the service life of the filter screen, and reduce maintenance costs.
[0016] 2) By setting several zigzag-shaped heat-conducting plates between the guide tubes, the air flow path inside the evaporator can be extended, increasing the residence time. The low temperature on the guide tubes can be transferred to the heat-conducting plates, which in turn increases the contact area with the air, enhancing the dehumidification effect. When the water vapor in the air comes into contact with the heat-conducting plates, it can condense and flow on their surface and drip into the bottom water tank. Several fins on both sides of the heat-conducting plates can further increase the contact area with the air and extend the residence time of the air inside the evaporator, further improving the dehumidification effect and ensuring dehumidification efficiency.

[0024] To facilitate understanding by those skilled in the art, the following is a detailed explanation in conjunction with the appendix. Figure 1-6 The technical solution of this utility model will be further described in detail below.
[0025] A cleanroom air supply device with dehumidification components includes an air inlet pipe 10, a dehumidification box 11, an air outlet pipe 12, a compressor 13, a dust removal mechanism 14, an evaporator 15, a condenser 16, a water storage tank 17, a water outlet pipe 18, and a fan 19. The dehumidification box 11 is fixedly connected to the air inlet pipe 10 and the air outlet pipe 12 at its two ends. The air inlet pipe 10 is equipped with a dust removal mechanism 14, and the air outlet pipe 12 is equipped with a fan 19. The dehumidification box 11 is equipped with an evaporator 15 and a condenser 16 from one end of the air inlet pipe 10 to one end of the air outlet pipe 12. The evaporator 15 and the condenser 16 are connected end to end by a pipe, and their other ends are connected to the inlet and outlet of the compressor 13, respectively. The water storage tank 17 is located below the evaporator 15 and is fixedly installed below the dehumidification box 11. The water outlet pipe 18 is fixedly connected to one side of the water storage tank 17.
[0026] The dust removal mechanism 14 includes a motor 141, a fixed bracket 142, a mounting frame 143, a filter screen 144, a protective cover 145, a collection box 1451, a cleaning rod 146, brush bristles 1461, a fixed rod 1462, connecting rod I 147, connecting rod II 148, and an eccentric wheel 149. The fixed bracket 142 is installed inside the air inlet pipe 10. The mounting frame 143 is movably mounted on the fixed bracket 142, and several filter screens 144 are mounted on the mounting frame 143. The mounting bracket 143 has synchronous pulleys at both ends of its rotating shaft. One end of the sprocket is connected to the synchronous pulley at the output end of the motor 141 via a synchronous belt, and the other end of the synchronous pulley is connected to the synchronous pulley at one end of the central rotating shaft of the eccentric wheel 149 via a synchronous belt. The central rotating shaft of the eccentric wheel 149 is movably mounted on the protective cover 145, which is fixedly mounted on the inner wall of the intake pipe 10. One end of the connecting rod II 148 is movably connected to the eccentric shaft on one side of the eccentric wheel 149. The other end of connecting rod II 148 is movably connected to connecting rod I 147. Several cleaning rods 146 are movably mounted on connecting rod I 147. Several brushes 1461 are provided on the cleaning rods 146. The other end of the cleaning rods 146 is movably mounted on the fixed rod 1462. The fixed rod 1462 is mounted on the protective cover 145. The bottom side of the protective cover 145 is open and a collection box 1451 is movably mounted thereon. After air enters the air intake pipe 10, it is filtered by the filter screen 144 to remove dust particles. During the filtration process, the motor 141 drives the mounting bracket 143 to rotate. At the same time, through the transmission of several synchronous pulleys and synchronous belts, the eccentric wheel 149 drives several connecting rods to swing back and forth. This causes the cleaning rods 146 to drive the brushes 1461 to repeatedly brush and clean the surface of the filter screen 144. Due to the setting of the protective cover 145, the dust particles are prevented from scattering and fall into the collection box 1451 for unified treatment due to gravity.
[0027] A 10mm-20mm gap is left between the protective cover 145 and the filter screen 144 to ensure that it does not contact the filter screen 144 to prevent damage, while also preventing dust from overflowing.
[0028] The collection box 1451 is provided with a handle 1452 on one side, which makes it convenient for staff to pull out the collection box 1451.
[0029] The evaporator 15 is equipped with several guide pipes 151 inside, and heat-conducting plates 152 are arranged between the guide pipes 151. The heat-conducting plates are installed in a zigzag shape between the guide pipes 151, and several fins 153 are provided on the heat-conducting plates 152. Through the several zigzag-shaped heat-conducting plates, the air flow path inside the evaporator 15 can be extended, the residence time can be increased, and the low temperature on the guide pipes 151 can be transferred to the heat-conducting plates 152. The heat-conducting plates 152 increase the contact area with the air, enhance the dehumidification effect, and allow water vapor in the air to condense and converge on the surface of the heat-conducting plates 152 when in contact with them, and drip into the bottom water storage tank 17. The several fins 153 on both sides of the heat-conducting plates 152 can further increase the contact area with the air, while extending the residence time of the air inside the evaporator 15 and improving the dehumidification efficiency.
[0030] The heat-conducting plate 152 and the fin plate 153 are made of copper. Copper has good thermal conductivity, which can further enhance the heat exchange efficiency with air and ensure the dehumidification effect.
[0031] A cleanroom air supply device with a dehumidification component operates as follows: Fresh air passes through the dust removal mechanism 14 inside the air inlet pipe 10 and is then cooled and condensed in the dehumidification box 11. The air first passes through the evaporator 15 for cooling and condensation. The compressor 13 lowers the temperature of the evaporator 15, causing the water vapor in the air to condense into water droplets at the dew point. The cooled and dry air is then heated to a specified temperature by the condenser 16 and sent into the cleanroom, forming a continuous cycle.
