Description

Technical Field

[0001] The invention relates to the technical field of air coolers, and in particular to an industrial air cooler. Background Art

[0002] Industrial air coolers are environmentally friendly products without compressors, refrigerants, or pollution. They use the principle of evaporative cooling of outdoor fresh air to cool down the room and conduct convection ventilation with the room to achieve the purpose of indoor ventilation and cooling. In the context of the rapid development of today's industrialization process, industrial air coolers, as key environmental control equipment, play an indispensable role in many industrial fields. They are crucial to maintaining a suitable production environment temperature and humidity, and ensuring production efficiency and product quality.

[0003] For example, in the Chinese patent with the authorization announcement number CN117663317B and the name of an industrial air cooler, a water pump can transport the water in the lower water tank upward to the upper water tank through a pipe. A plurality of conical water pipes connected to the interior of the upper water tank and corresponding to the wet curtain are installed at the bottom end of the upper water tank. The water in the upper water tank slides to the wet curtain through the conical water pipes. The airflow blown by the air blower passes through the wet curtain. The wet curtain reduces the temperature of the airflow, thereby causing the airflow to cool the external environment.

[0004] With regard to the above-mentioned related technologies, different external environments require different airflow temperatures when the airflow is equal in size. When the water in the wet curtain is in a saturated state, it is difficult to adjust the temperature of the airflow passing through by adding water to the wet curtain. Therefore, the water in the wet curtain needs to be in an unsaturated state. However, when the cooling water falls to the wet curtain, the water will flow to the lower end of the wet curtain only when the water at the upper end of the wet curtain becomes saturated. Therefore, it is difficult for the cooling water to fall to the wet curtain through the conical water pipe while maintaining the unsaturated state. At the same time, the cooling water is evenly distributed on the surface of the wet curtain, so that the airflow and water are in uniform contact, thereby having a negative impact on the adjustable cooling function of the outside world. Summary of the invention

[0005] In view of this, the present invention provides an industrial air cooler, aiming to solve the problem that it is difficult to evenly distribute the cooling water on the surface of the wet curtain while maintaining an unsaturated state when cooling water falls to the wet curtain through a tapered water pipe.

[0006] To solve the above technical problems, the present invention provides an industrial air cooler, comprising a fan housing and a fan, wherein a plurality of bendable wet curtains are arranged in the horizontal direction in the fan housing; a liquid storage tank is fixedly connected to the bottom of the fan housing, and a plurality of infusion mechanisms for conveying cooling liquid to the wet curtains are arranged in the fan housing; the infusion mechanism comprises two supporting shells slidably connected to the liquid storage tank and internally communicated, the opposite vertical surfaces of the two supporting shells are fixedly connected to support plates, the wet curtain is fixedly connected between the two support plates, a supporting rod is fixedly connected between the two supporting shells, and transmission pistons slidably connected to the supporting shells are fixedly connected on both sides of the supporting rod, and a plurality of liquid outlet holes for conveying cooling liquid to the wet curtains are opened on the side walls of the supporting shell; a connecting rod is fixedly connected between each adjacent two infusion mechanisms, and a driving mechanism is arranged in the fan housing, and the driving mechanism is used to drive the two supporting shells in the same infusion mechanism to move away from each other or approach each other.

[0007] By adopting the above technical solution, adjusting the speed of the supporting shell movement can, on the one hand, pump the coolant and deliver it to the wet curtain, and can control the amount of coolant received on the surface of the wet curtain, and on the other hand, the supporting shell delivers the coolant to the wet curtain during the movement, and the movement of the liquid outlet improves the uniformity of the coolant sprayed to the wet curtain. Controlling the amplitude of the wet curtain from flattening to bending can control the area of ​​contact between the wind flow and the wet curtain, thereby controlling the concentration of the coolant contained in the wind flow, and further controlling the temperature of the output wind flow.

[0008] Optionally, the driving mechanism includes a rotation source, a driving gear and a transmission rack, the rotation source is fixedly connected to the top wall of the fan housing, the driving gear is fixedly sleeved on the driving shaft of the rotation source, two transmission racks are provided and both can engage with the driving gear, and each transmission rack is fixedly connected to a supporting housing.

[0009] Optionally, the liquid storage tank is connected to the supporting shell via an infusion tube, and a one-way valve is connected in series in the infusion tube.

[0010] Optionally, a filter plate is fixedly connected to a side wall of the fan housing away from the fan, and the filter plate is located between the infusion mechanism and the fan housing.

[0011] By adopting the above technical solution, the filter plate filters the dust in the airflow, thereby reducing the probability of the dust in the airflow getting stuck in the wet curtain.

[0012] Optionally, a brush for cleaning dust in the filter plate is connected to the outer side of the support shell.

[0013] Optionally, the brush is rotatably connected to the support shell, the brush is fixedly connected to a transmission gear, and a connecting rack that can mesh with the transmission gear is fixedly connected inside the fan shell.

[0014] By adopting the above technical solution, the support shell can drive the brush to move when it moves, and the transmission gear moves synchronously with the brush. Since the transmission gear is meshed with the connecting rack, the transmission gear can rotate during the movement, and the brush rotates synchronously with the transmission gear, thereby improving the efficiency of the brush in cleaning dust in the filter plate.

[0015] Optionally, the support shell is fixedly connected to a connecting plate, and one end of the connecting plate away from the support shell is fixedly connected to a collecting shell, and the collecting shell is used to receive dust scraped off the filter plate by the brush.

[0016] By adopting the above technical solution, the dust scraped off the filter plate by the brush enters the collection shell, and the collection shell can block and buffer the wind flow at the brush position, thereby reducing the probability of the scraped dust being lifted up by the wind flow again.

[0017] Optionally, a cooling pipe is fixedly connected to the fan housing, and the cooling pipe is bent and arranged between the fan and the infusion mechanism.

[0018] By adopting the above technical solution, coolant flows in the cooling pipe, and the wind flows through the cooling pipe to perform heat exchange with the cooling pipe, thereby improving the effect of cooling the wind.

[0019] In summary, compared with the prior art, the beneficial technical effects of the present invention are as follows: adjusting the speed of movement of the supporting shell can, on the one hand, pump the coolant and deliver the coolant to the wet curtain, and can control the amount of coolant received on the surface of the wet curtain, and on the other hand, the supporting shell delivers the coolant to the wet curtain during the movement, and the movement of the liquid outlet improves the uniformity of the coolant sprayed on the wet curtain. At the same time, the supporting shell enables the wet curtain to be alternately bent and stretched during the movement, and the wet curtain can generate vibrations from bending to stretching, which increases the speed of the coolant flowing on the surface of the wet curtain and further improves the uniformity of the coolant distribution on the surface of the wet curtain. In addition, controlling the amplitude of the wet curtain from stretching to bending can control the area of ​​contact between the wind flow and the wet curtain, thereby controlling the concentration of the coolant contained in the wind flow, and then controlling the temperature of the output wind flow under the premise of determining the size of the wind flow, which is conducive to realizing the adjustable cooling function to the outside world.

DETAILED DESCRIPTION

[0028] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 7 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0029] This embodiment provides an industrial air cooler. Figure 1 , Figure 2 and Figure 3 An industrial air cooler includes a fan housing 1, a wet curtain 12, a liquid storage tank 13, a liquid infusion mechanism 2 for conveying cooling liquid to the wet curtain 12, and a driving mechanism 4.

[0030] Reference Figure 2 and Figure 3The fan housing 1 is erected on a horizontal plane. A fan 11 is rotatably connected inside the fan housing 1. The fan 11 is connected to a power source and can rotate to generate wind flow. A wet curtain 12 is located inside the fan housing 1 and is provided with a plurality of wet curtains 12 along the length direction of the fan housing 1. The wet curtain 12 is a soft material that can be bent, and the wind flow can pass through the wet curtain 12. A liquid reservoir 13 is fixedly connected to the bottom of the fan housing 1, and the liquid reservoir 13 is used to store coolant. An infusion mechanism 2 is provided above the liquid reservoir 13. The number of the infusion mechanisms 2 is equal to the number of the wet curtains 12, and the infusion mechanisms 2 are provided one-to-one with the wet curtains 12. The infusion mechanism 2 is used to transport the coolant in the liquid reservoir 13 to the wet curtains 12.

[0031] Reference Figure 4 and Figure 5 The infusion mechanism 2 includes a support shell 21, a support plate 22, a support rod 23 and a transmission piston 24. Two support shells 21 are provided and are slidably connected to the liquid storage tank 13, and the support shell 21 is connected to the liquid storage tank 13 through an infusion tube 25, and a one-way valve 251 is connected in series in the infusion tube 25, and the one-way valve 251 limits the coolant in the support shell 21 from flowing back to the liquid storage tank 13. Two support plates 22 are provided and are fixedly connected to the opposite vertical surfaces of the two support shells 21. The support rod 23 is vertically fixedly connected between the two support shells 21, and the transmission piston 24 is provided with two and fixedly connected to both sides of the support rod 23. The transmission piston 24 is slidably connected to the inside of the support shell 21. The side wall of the support shell 21 is provided with a plurality of liquid outlets 211 for delivering the coolant to the wet curtain 12 in the horizontal and vertical directions. A connecting rod 3 is fixedly connected between each adjacent two infusion mechanisms 2, and specifically, the connecting rod 3 is fixedly connected to the support plate 22. The driving mechanism 4 is disposed at the upper end of the fan housing 1 , and is used to drive the two supporting housings 21 in the same infusion mechanism 2 to move away from each other or move closer to each other.

[0032] The transmission piston 24 is fixed in the fan housing 1 through the support rod 23, the driving mechanism 4 drives the two support housings 21 away from each other, the transmission piston 24 pumps the coolant to the support housing 21 through the infusion tube 25, the driving mechanism 4 drives the two support housings 21 closer to each other, and the transmission piston 24 sprays the coolant to the wet curtain 12 through the outlet hole 211. The relative movement speed of the support housing 21 and the transmission piston 24 is controlled, so that the amount of coolant received by the surface of the wet curtain 12 in the same time can be controlled. The fan 11 is connected to an external power supply and rotates to generate wind flow, and the wet curtain 12 cools the wind flow passing through, so as to achieve the function of the wind flow cooling the external working environment. In the process of the wind flow passing through the wet curtain 12, the driving mechanism 4 drives the two support housings 21 in the same infusion mechanism 2 to move away from and close to each other alternately, so that the wet curtain 12 can be stretched and bent alternately.

[0033] When the wet curtain 12 is bent, the airflow passing through the wet curtain 12 is cooled, and the airflow not passing through the wet curtain 12 is directly output. Since a plurality of infusion mechanisms 2 are arranged in the horizontal direction, the airflow not passing through the wet curtain 12 and the airflow passing through the wet curtain 12 are alternately arranged in the horizontal direction. By utilizing the high irregularity of the flow of gas molecules, the output airflow not passing through the wet curtain 12 and the airflow passing through the wet curtain 12 can be mixed.

[0034] Adjusting the speed of the movement of the supporting shell 21 can, on the one hand, pump the coolant and deliver it to the wet curtain 12, and can control the amount of coolant received on the surface of the wet curtain 12. On the other hand, the supporting shell 21 delivers the coolant to the wet curtain 12 during the movement, and the movement of the liquid outlet 211 improves the uniformity of the coolant sprayed on the wet curtain 12. At the same time, the supporting shell 21 enables the wet curtain 12 to be alternately bent and stretched during the movement, and the wet curtain 12 can generate vibration from bending to stretching, which increases the speed of the coolant flowing on the surface of the wet curtain 12 and further improves the uniformity of the coolant distribution on the surface of the wet curtain 12. In addition, controlling the amplitude of the wet curtain 12 from stretching to bending can control the area of ​​contact between the wind flow and the wet curtain 12, thereby controlling the concentration of the coolant contained in the wind flow, and then controlling the temperature of the output wind flow under the premise of determining the wind flow size, which is conducive to realizing the adjustable function of cooling the outside world.

[0035] Reference Figure 4 The driving mechanism 4 includes a rotation source 41, a driving gear 42 and a transmission rack 43. The rotation source 41 is fixedly connected to the top wall of the fan housing 1. The driving gear 42 is fixedly sleeved on the driving shaft of the rotation source 41. Two transmission racks 43 are provided and can mesh with the driving gear 42. The two transmission racks 43 are located on both sides of the driving gear 42. The rotation source 41 drives the two transmission racks 43 to move away from or closer to each other through the driving gear 42. Each transmission rack 43 is fixedly connected to a supporting shell 21 respectively. The transmission rack 43 drives the two supporting shells 21 of the same infusion mechanism 2 to move away from or closer to each other in the opposite directions.

[0036] Reference Figure 2 and Figure 6 A filter plate 14 is fixedly connected to the side wall of the fan housing 1 away from the fan 11. The filter plate 14 is located between the infusion mechanism 2 and the fan housing 1. The filter plate 14 filters dust in the airflow to reduce the probability of dust in the airflow being stuck in the wet curtain 12.

[0037] Reference Figure 6 and Figure 7The outer side of the support housing 21 is connected to a brush 5 for cleaning dust in the filter plate 14. The brush 5 is rotatably connected to the support housing 21, and a transmission gear 51 is fixedly connected to the brush 5. A connecting rack 15 that can mesh with the transmission gear 51 is fixedly connected to the fan housing 1. When the support housing 21 moves, the brush 5 can be driven to move, and the transmission gear 51 moves synchronously with the brush 5. Since the transmission gear 51 meshes with the connecting rack 15, the transmission gear 51 can rotate during the movement, and the brush 5 rotates synchronously with the transmission gear 51, thereby improving the efficiency of the brush 5 in cleaning dust in the filter plate 14.

[0038] Reference Figure 6 and Figure 7 The supporting shell 21 is fixedly connected with a connecting plate 212, and the connecting plate 212 is fixedly connected with a collecting shell 6 at one end away from the supporting shell 21. The collecting shell 6 moves synchronously with the brush 5. The collecting shell 6 is located at the end of the filter plate 14 away from the brush 5, and the opening of the collecting shell 6 is arranged close to the filter plate 14. The wind direction determines that the dust mainly adheres to the end of the filter plate 14 close to the collecting shell 6, and the dust scraped off the filter plate 14 by the brush 5 enters the collecting shell 6. In addition, the collecting shell 6 and the brush 5 are arranged opposite to each other along the flow direction of the wind flow, and the collecting shell 6 can block and buffer the wind flow at the brush 5 position, reducing the probability that the scraped dust is lifted up by the wind flow again.

[0039] Reference Figure 2 A cooling pipe 7 is fixedly connected to the fan housing 1. The cooling pipe 7 is bent and arranged between the fan 11 and the infusion mechanism 2. Cooling liquid flows in the cooling pipe 7. The temperature of the cooling liquid in the cooling pipe 7 can be lower than the temperature of the cooling liquid in the wet curtain 12. The wind passes through the cooling pipe 7 to exchange heat with the cooling pipe 7, which can further cool the wind.

[0040] The implementation principle of an industrial air cooler according to an embodiment of the present invention is as follows: the driving mechanism 4 drives the two supporting shells 21 away from each other, the transmission piston 24 pumps the coolant to the supporting shell 21 through the infusion tube 25, the driving mechanism 4 drives the two supporting shells 21 closer to each other, and the transmission piston 24 sprays the coolant to the wet curtain 12 through the liquid outlet 211. The fan 11 is connected to an external power source and rotates to generate wind flow, and the wet curtain 12 cools the wind flow passing through, thereby achieving the function of the wind flow cooling the external working environment. In the process of the wind flow passing through the wet curtain 12, the driving mechanism 4 drives the two supporting shells 21 in the same infusion mechanism 2 to move away from and closer to each other alternately, so that the wet curtain 12 can be stretched and bent alternately.

[0041] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
