Description

Technical Field

[0001] The present invention relates to the technical field of air coolers, in particular to an air inlet pretreatment type humidifying air cooler. Background Art

[0002] An air cooler is a heat exchange device that uses air as a cooling medium, primarily used to cool warm air to a desired temperature. It consists of a tube bundle, a tube box, and a fan. It achieves cooling or condensation by exchanging heat between the warm fluid within the tubes and the air outside. Adiabatic humidification isolates heat exchange and increases air humidity, achieving both cooling and humidification through the absorption of heat through the evaporation of sprayed water mist.

[0003] The gap between adjacent fins inside the air-cooled unit is small, and as the equipment runs for a long time, a large amount of dirt will accumulate in the area between the fins, which will seriously reduce the heat transfer efficiency of the equipment. At the same time, there are many fins and the gaps are small, so the dirt cannot be removed in time. Over time, the process performance of the equipment will continue to decline, the effective service life of the equipment will be shortened, and the cost will increase; In addition, the fins on the outer surface of the fins are densely distributed, the channel is small and the wind resistance is large. Once the air is not pre-treated, the subsequent air flow entering the inner cavity of the air-cooled unit will carry dust particles, and the dust particles will cause blockage in the narrow channel, thereby affecting the fluidity of the air flow in the inner cavity of the air-cooled unit. Once the air is damp, the dust particles will accumulate and adhere to the fins, and in severe cases, it will cause fin corrosion. In addition, relying on a single filter on the air duct of the air cooler can only filter the air in the initial stage. As the dirt on the surface of the filter increases, the efficiency of air intake will be greatly hindered. At the same time, the filter with accumulated dirt will also be damaged due to the increase in air pressure.

[0004] In view of this, an air pretreatment humidifying air cooler is designed to solve the above problems. Summary of the Invention

[0016] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. The present invention installs an air duct laying mechanism at the bottom of the air-cooling unit and installs a fan at the top of the air-cooling unit. As the fan runs, the outside air will be sucked in along the multi-stage air purification mechanism. During the air entering the multi-stage air purification mechanism, it will be filtered at three levels until the dust in the air is completely filtered out. The airflow after squeezing out the multi-stage air purification mechanism will be input into the fins inside the air-cooling unit along the protective cover and the wide-surface filter.

[0017] 2. The present invention installs a spray part through the internal movement of the protective cover. When the multi-stage air purification mechanism has been running for a long time and a certain amount of dirt is deposited on the surface, the spray part is controlled to apply extrusion force to the air inlet pipe until the plug is squeezed out of the air cylinder. The cleaning liquid is transmitted along the spray part through the injection pipe. Finally, the cleaning liquid will efficiently clean the air duct of the multi-stage air purification mechanism, thereby achieving the purpose of autonomous cleaning of the air duct by the device and preventing excessive accumulation of dirt from affecting the efficiency of subsequent airflow input.

[0018] 3. The present invention fixes a scraper head on the end of the air inlet pipe that passes through the inner cavity of the air cylinder. When the metal filter is cleaned by liquid washing, the fine dust that passes through the metal filter will agglomerate on the moist inner wall of the metal filter due to the moisture on the air surface. In order to prevent the agglomerated dirt from clogging the mesh, the scraper head will slide along the inner wall of the metal filter in conjunction with the subsequent washing with cleaning liquid, thereby improving the cleanliness of the inner cavity of the metal filter and further increasing the service life of the device.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0022] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0023] An air inlet pretreatment humidifying air cooler provided by some embodiments of the present invention will be described below with reference to the accompanying drawings. Example 1

[0024] Combine Figures 1 to 9 As shown, the present invention provides an air inlet pretreatment humidifying air cooler, which includes an air cooling unit 100, an air duct laying mechanism 200 installed on the air cooling unit 100, three groups of air outlet cleaning mechanisms 300 installed on the air duct laying mechanism 200, and multiple groups of multi-stage air purification mechanisms 400 installed in the air outlet cleaning mechanism 300. The air duct laying mechanism 200 is used to increase the airflow surface for processing airflow, the air outlet cleaning mechanism 300 is used to provide a transmission channel for the inhaled airflow, and provide a cleaning platform for the multi-stage air purification mechanism 400. The multi-stage air purification mechanism 400 is used to force filtration of external air and maintain a constant airflow input amount.

[0025] The air duct laying mechanism 200 includes a bottom plate 210 adapted to be attached to the air cooling unit 100, and three evenly distributed rectangular notches are opened inside the bottom plate 210; The air outlet cleaning mechanism 300 includes a pad 310 mounted on a rectangular notch, a shield 320 fixedly mounted on the inner side of the pad 310, a slot 3202 defined on the outer wall of the shield 320, a spray element 350 movably mounted within the slot 3202, and located within the inner cavity of the shield 320. A sealing plate 340 is fixedly mounted on the outer end of the shield 320, and symmetrically mounted internal and external slides 3501 and 3502 are fixedly mounted on the spray element 350. The air duct laying mechanism 200 also includes an injection pipe 260 mounted on the spray element 350. The injection pipe 260 consists of three ends and a conduit. A first guard plate 220 is provided on one side of the base plate 210, a second guard plate 230 is provided on the other side of the base plate 210, and three wide-surface filters 250 are installed inside the first and second guard plates 220, 230. Pre-installed holes 240 are provided in each of the first and second guard plates 220, 230. The three spray elements 350 are symmetrically located at the three rectangular notches. A U-shaped groove is formed at the top of the bracket 330, and the spraying element 350 is movably installed in the U-shaped groove; A limiting groove 3201 is provided on the outer side of the shield 320 , and a backing plate 3102 and a tension spring 3103 fixedly mounted on the backing plate 3102 are fixedly mounted on one side of the shield 320 near the limiting groove 3201 ; The other end of the tension spring 3103 is fixedly mounted on the spray element 350, and the external slide plate 3502 fits in the limiting groove 3201; The outer surface of the sealing plate 340 is fixedly mounted with a plurality of uniformly distributed protective sleeves 3401 , and the protective sleeves 3401 are used to enhance the stability and protection of the protective pad 310 ; The multi-stage air purification mechanism 400 includes an air cylinder 410 installed inside the sealing plate 340, a metal filter 4101 fixedly installed inside the air cylinder 410, an air inlet pipe 420 movably installed in the inner cavity of the air cylinder 410, a support rod 430 fixedly installed in the air inlet pipe 420, and a plug 4301 fixedly installed at the other end of the support rod 430 and attached to the air cylinder 410.

[0026] When in use, start the fan in advance. As the fan runs, outside air will enter through the mesh holes on the outer wall of the air cylinder 410. The coarse filter mesh holes on the outer wall of the air cylinder 410 will block large particles of impurities in the air. After the large particles of impurities are blocked, the airflow is transmitted to the inner cavity of the air cylinder 410 along the mesh holes of the metal filter 4101, and the metal filter 4101 will further filter the air. The finely filtered airflow is then transmitted along the air holes 4201 toward the inner cavity of the shield 320. At this point, the airflow is input from the inner cavity of the shield 320 into the three rectangular slots inside the bottom plate 210. Finally, the finely filtered airflow is filtered for the third time by the three wide-surface filters 250. At this time, the airflow passing through the three wide-surface filters 250 will cooperate with the condensate to efficiently cool the fins, thereby preventing dirt in the airflow from adhering to the fin surface after being damp. Reducing the airflow of dirt can effectively increase the service life of the device and maintain a constant airflow input. Example 2

[0027] Combine Figure 8 and Figure 9 As shown, based on Example 1, a plug hole 4202 is opened in the middle of the air cylinder 410, and the support rod 430 is adapted to be inserted into the plug hole 4202, the inner cavity of the air intake pipe 420 is opened with multiple air holes 4201 evenly distributed, a scraper head 450 is fixedly installed on the air intake pipe 420, and a filter element 460 is fixedly installed between the air intake pipe 420 and the scraper head 450; A spring 440 is connected between the air cylinder 410 and the air inlet pipe 420. The outer wall of the air cylinder 410 is provided with coarse filter mesh holes, and the metal filter 4101 is a fine filter surface structure. The top of the spraying member 350 is fixedly provided with evenly distributed cylindrical ports, and a booster nozzle is fixedly provided inside the cylindrical port. The cleaning liquid after passing through the booster nozzle is used to flush dirt on the mesh surface of the filter element 460.

[0028] Preferably, a groove is provided on the outside of the air intake pipe 420, and the bottom end of the air cylinder 410 is movably installed in the groove. When the spring 440 applies an extrusion force to the air intake pipe 420, the plug 4301 fixedly installed on the outer end of the support rod 430 will be subjected to the extrusion force and provide an effective clamping force on the port at the outer end of the air cylinder 410. At this time, the cavity formed by the air cylinder 410 and the metal filter 4101 can inhale the outside air at a constant pressure, thereby ensuring a constant airflow. Example 3

[0029] Combine Figures 3 to 7 As shown, in the above embodiment, the air duct laying mechanism 200 further includes two sets of clamps 270 fixedly mounted on the base plate 210, hydraulic components 2701 fixedly mounted in the two sets of clamps 270, an end 2702 mounted on the hydraulic components 2701, a traction arm 2703 movably mounted on the end 2702, and a truss 2704 movably mounted on the other end of the traction arm 2703, and the end of the spraying element 350 that passes through the slide groove 3202 is inserted into the truss 2704; The inner wall of the shield 320 is provided with two symmetrically distributed slots 3101 , and the brackets 330 are inserted into the slots 3101 . Two bolts 3301 are inserted into the bracket 330 , and the two bolts 3301 are fixed to the inner wall of the shield 320 .

[0030] Preferably, two sets of clamps 270 are welded to the outer surface of the base plate 210. In the initial state, the hydraulic sub-rod in the hydraulic part 2701 will cooperate with the end 2702 to pull the traction arm 2703 and the truss 2704 to shrink. At this time, the truss 2704 fits on the protective pad 310, and the spray part 350 supported by the truss 2704 will reserve a sufficiently large gap with the air cylinder 410 to provide an effective transmission channel for the subsequent filtered airflow. The bracket 330 fixed by the bolt 3301 can provide stabilization protection for the reciprocating spray part 350, and cooperate with the built-in slide 3501 and the external slide 3502 to fit tightly against the slide groove 3202, thereby ensuring that the airflow and air pressure in the inner cavity of the shield 320 remain stable.

[0031] The working principle and use process of the present invention are as follows: the assembled bottom plate 210, the first guard plate 220 and the second guard plate 230 are installed on the bottom of the air cooler in advance, and then the fan is installed on the top of the air cooling unit 100. Figure 1 In the manner shown in the figure, as the fan operates, air is drawn in along the direction of the three sets of air duct laying mechanisms 200 and is eventually discharged from the fan; In the initial state, the truss 2704 is subjected to a downward traction force, and drives the three groups of spray elements 350 to descend to the bottom of the inner cavities of the three shields 320, and the air cylinder 410, the air hole 4201 and the inner cavity of the shield 320 are connected. As the fan runs, the air drawn from top to bottom will first enter through the air hole on the outer wall of the air cylinder 410, and the airflow passing through the air hole will be filtered by the metal filter 4101. The airflow after the initial filtration will be transmitted along the air hole 4201 to the inside of the shield 320, and the airflow finally transmitted to the inner cavity of the shield 320 will be filtered for the second time by the wide-surface filter 250 until the air after the second filtration pre-treats the air-cooled airflow of the air-cooling unit 100. Since there are a lot of dust particles and other impurities in the outside air, the amount of dirt accumulated on the surface of the air cylinder 410 and the metal filter 4101 that have been used for a long time will continue to increase. Therefore, the hydraulic component 2701 is operated until the hydraulic sub-rod in the hydraulic component 2701 cooperates with the end 2702 to drive the traction arm 2703 to extend. As the truss 2704 is lifted upward, the truss 2704 will drive the three spray components 350 to rise synchronously. Finally, the ends of the spray components 350 will be inserted into the interior of multiple evenly distributed air inlet pipes 420 at the same time, and then the injection pipe 260 will be used to transmit the cleaning liquid to the inner cavity of the three spray components 350. Finally, the cleaning liquid will flow into the end of the spray component 350. The inner cavity of the air intake pipe 420, and the dirt accumulated on the metal filter 4101 and the surface of the air cylinder 410 are cleared along the air hole 4201. At the same time, the filter element 460 that is first pressurized will also be quickly cleaned. As the spray part 350 continues to extend, the air intake pipe 420 and the support rod 430 will push the plug 4301 outward, and the dirt cleaned by the cleaning liquid can be effectively released. After the cleaning of the device is completed, the hydraulic sub-rod in the control hydraulic part 2701 is reset until the spray part 350 is reset to the initial position of the inner cavity of the shield 320. At this time, the device can provide long-term pretreatment for the air flow entering the air cooling unit 100, thereby improving the constancy of the air flow.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
