Description

TECHNICAL FIELD

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

[0002] An air cooler is a heat exchange device using air as a cooling medium, mainly used for cooling warm flow to the required temperature. It is mainly composed of tube bundles, tube boxes, fans and other main parts, and through the heat exchange between the warm fluid in the tube and the air outside the tube, the cooling or condensing effect is achieved; adiabatic humidification refers to the insulation of heat exchange and the increase of air humidity, and the double purposes of cooling and humidifying are achieved by using water mist evaporation to absorb heat.

[0003] The gap between the two adjacent fins in the air cooling unit is small, and with the long-time operation of the equipment, 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, the fins are many and the gap is small, and the dirt cannot be cleaned in time, so that the process performance of the equipment will continue to decline, the effective use time of the equipment will be shorter, and the cost will be increased.

[0004] In addition, the fins on the outer surface of the fin are densely distributed, and the channel is small and the air resistance is large. Once the air is not pretreated, the dust particles will cause blockage in the narrow channel after being wrapped in the subsequent air flow into the inner cavity of the air cooling unit, thereby affecting the flow of the air flow in the inner cavity of the air cooling unit. Once the air is damp, the dust particles will accumulate and adhere to the fins, which will cause corrosion of the fins in severe cases. In addition, relying on a single filter screen on the air duct of the air cooler can only filter the air in the initial stage. With the increase of dirt on the surface of the filter screen, the efficiency of air suction will be greatly hindered. At the same time, the filter screen with accumulated dirt will also be damaged due to the increase of air pressure.

[0005] In view of this, an air inlet pretreatment type humidifying air cooler is designed to solve the above problems. SUMMARY

[0014] The three spray elements are symmetrically arranged at the three rectangular grooves.

[0015] In a preferred example, the inner wall of the guard cover is provided with two symmetrically distributed clamping grooves, and a support is inserted into the clamping grooves; the inner part of the support is inserted into two bolts, and the two bolts are fixed to the inner wall of the guard cover.

[0016] The top end of the bracket is provided with a U-shaped groove, and the spraying member is movably installed in the U-shaped groove.

[0017] In a preferred example, the outer side of the shield is provided with a limiting groove, and a gasket is fixedly installed on one side of the shield close to the limiting groove, and a tension spring is fixedly installed on the gasket.

[0019] In a preferred example, the outer surface of the sealing plate is fixedly installed with a plurality of sheaths that are uniformly distributed, and the sheaths are used to enhance the stability protection of the gasket.

[0020] In a preferred example, the outer wall of the air cylinder is provided with a coarse filter mesh, and the metal filter mesh is a fine filter mesh structure.

[0021] In a preferred example, the top of the spraying member is fixedly installed with a plurality of cylindrical ports that are uniformly distributed, and a booster nozzle is fixedly installed in the cylindrical port, and the cleaning liquid after passing through the booster nozzle is used to flush the dirt on the filter mesh surface.

[0022] By adopting the above technical scheme, the present application has the following beneficial effects:

[0023] 1. The air cooling unit is installed with a wind channel laying mechanism at the bottom and a fan at the top. With the operation of the fan, external air is sucked into the multi-stage air purification mechanism, and is filtered for three times during the process of entering the multi-stage air purification mechanism, so that the dust in the air is completely filtered out.

Embodiment 3

[0059] In combination with Figures 3 to 7 As shown in the above embodiment, the air duct laying mechanism 200 further comprises two groups of clamps 270 fixedly installed on the bottom plate 210, hydraulic components 2701 fixedly installed in the two groups of clamps 270, end heads 2702 installed on the hydraulic components 2701, traction arms 2703 movably installed on the end heads 2702, and trusses 2704 movably installed at the other end of the traction arms 2703, and the spraying member 350 penetrates the end of the sliding groove 3202 and is inserted into the truss 2704;

[0060] The inner wall of the shield 320 is provided with two symmetrically distributed clamping grooves 3101, a support 330 is inserted into the clamping grooves 3101, the inner part of the support 330 is inserted with two bolts 3301, and the two bolts 3301 are fixed on the inner wall of the shield 320.

[0061] Preferably, the two groups of clamps 270 are welded on the outer surface of the bottom plate 210, in the initial state, the hydraulic sub-rod in the hydraulic part 2701 can cooperate with the end 2702 to pull the traction arm 2703 and the truss 2704 to shrink, at this time, the truss 2704 is adapted to be attached to the protective pad 310, and the spraying part 350 supported by the truss 2704 can provide a large enough gap with the air cylinder 410 to provide an effective transmission channel for the subsequent filtered air flow, and the support 330 fixed by the bolt 3301 can provide stability protection for the reciprocating spraying part 350, and cooperate with the built-in sliding plate 3501 and the external sliding plate 3502 to tightly attach to the sliding groove 3202, so as to ensure that the air flow and air pressure in the inner cavity of the shield 320 are stable.

[0062] The working principle and use process of the application are as follows: the combined bottom plate 210, the first protective plate 220 and the second protective plate 230 are installed at the bottom of the air cooler in advance, and the fan is installed at the top of the air cooling unit 100. Figure 1 With the operation of the fan, air is sucked along the direction of the three groups of air duct laying mechanisms 200, and finally discharged from the fan;

[0063] In the initial state, the truss 2704 is subjected to downward traction and drives the three groups of spraying parts 350 to descend to the bottom of the inner cavity of the three shields 320, and the air cylinder 410, the air hole 4201 and the inner cavity of the shield 320 form a communication state, with the operation of the fan, the air sucked from top to bottom first enters along the air hole of the outer wall of the air cylinder 410, the air flow passing through the air hole is filtered by the metal filter screen 4101, and the initially filtered air flow is transmitted to the inner part of the shield 320 along the air hole 4201, and finally the air flow in the inner cavity of the shield 320 is subjected to secondary filtration by the wide filter screen 250, until the secondary filtered air is preprocessed for the air cooling flow of the air cooling unit 100.

[0064] Because there are a lot of dust particles and other impurities in the external air, the amount of dirt accumulated on the surface of the air cylinder 410 and the metal filter screen 4101 will also continue to increase over time. Therefore, the hydraulic component 2701 is operated until the hydraulic sub-rod cooperation end 2702 of the hydraulic component 2701 drives the traction arm 2703 to extend. After the truss 2704 is lifted upward, the truss 2704 will drive the three spray components 350 to be lifted synchronously. Finally, the end of the spray component 350 will be inserted into the multiple air inlet pipes 420 inside at the same time. Then, the cleaning liquid is transmitted into the three spray components 350 by using the liquid injection pipe 260. Finally, the cleaning liquid will flow into the inner cavity of the air inlet pipe 420 through the end of the spray component 350, and along the air hole 4201 to clean the dirt accumulated on the surface of the metal filter screen 4101 and the air cylinder 410. At the same time, the filter element 460 that is first pressed will also be quickly cleaned. As the spray component 350 continues to extend, the air inlet pipe 420 and the supporting rod 430 will push the plug 4301 to extend outward. The dirt cleaned by the cleaning liquid can be effectively released. Until the device is cleaned, the hydraulic sub-rod in the control hydraulic component 2701 is reset until the spray component 350 is reset to the initial position in the inner cavity of the protective cover 320. At this time, the device can provide persistent pretreatment for the air flow entering the air cooling unit 100, thereby improving the constancy of air flow.

[0065] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the claims and their equivalents.
