Description

Technical Field

[0001] The utility model relates to the technical field of spraying of evaporative air coolers, in particular to a circulating spraying device of an evaporative air cooler. Background Art

[0002] An evaporative air cooler is an efficient and energy-saving cooling device that integrates water cooling and air cooling, heat transfer and mass transfer processes and has the advantages of both. During operation, it usually requires the use of a spray device for spraying to achieve the effect of efficient cooling. For example, the publication number CN202470872U is an evaporative air cooler spray device, which includes a spray water pipe, a nozzle installed on the spray water pipe, and a flow regulating valve. The spray water pipe is composed of a spray water main pipe and spray water branches arranged in multiple layers side by side. The spray water main pipe connects each spray water branch, and a nozzle is installed on the spray water branch. A flow regulating valve is provided at the water inlet of the spray water branch. It is used to cool the hot air generated in industrial production, effectively reduce heat, remove dust, and improve the condensation effect. However, the evaporative air cooler spray device still has the following shortcomings during actual use:

[0003] After spraying the evaporative air cooler, the traditional spray device directly discharges the spray water, causing waste. There is no structure to recover and recycle the excess liquid after spraying. In addition, after the liquid is sprayed on the evaporative air cooler, it will carry some impurities and flow out, which can easily cause blockage of structures such as drainage pipes. In response to the above problems, it is urgent to carry out innovative design based on the original spray device. Utility Model Content

[0004] The purpose of the present utility model is to provide a circulating spray device for an evaporative air cooler, so as to solve the problem proposed in the above background technology that the traditional spray device directly discharges the spray water after spraying the evaporative air cooler, causing waste, lacks a structure for recovering and recycling the excess liquid after spraying, and after the liquid is sprayed on the evaporative air cooler, it will carry some impurities and flow out, which is easy to cause blockage of structures such as drainage pipes.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a circulating spray device for an evaporative air cooler, comprising a water storage tank, a protective plate fixed to the upper edge of the water storage tank, and a concave upper surface of the water storage tank, an electric motor mounted on the side of the water storage tank, and an output shaft of the electric motor connected to a connecting shaft, a turbine mounted on one end of the connecting shaft close to the electric motor, and a space outside the turbine communicating with a water pipe;

[0006] The device further comprises: the outer side of the connecting shaft is connected to the cleaning mechanism via two meshing gears, the cleaning mechanism is arranged above the water storage tank, and a through groove for recovering liquid is provided in the recess of the water storage tank;

[0007] The spraying mechanism and the cooling mechanism are both arranged above the water storage tank, and the height of the spraying mechanism is lower than that of the cooling mechanism.

[0008] Preferably, the distribution range of the gear teeth on the connecting shaft is 1 / 2 of its circumference, and the cleaning mechanism includes a transmission shaft with a bearing running through the side of the water tank, and a spring is provided at the rotation point of the transmission shaft and the water pipe. When the lower gear is not engaged with the upper gear, the resilience of the spring can drive the transmission shaft and the cleaning brush to rotate in the other direction.

[0009] Preferably, a cleaning brush is provided on the outer side of the transmission shaft, and the bottom of the cleaning brush is in contact with the surface of the filter screen, and the filter screen is fixed on the inner side of the through groove. The transmission shaft drives the cleaning brush to sweep over the filter screen to prevent impurities intercepted by the filter screen from clogging it.

[0010] Preferably, the spray mechanism includes a movable shaft passing through the top of the water pipe, and one end of the movable shaft is connected to the transmission shaft through a pulley mechanism, and the movable shaft and the water pipe are rotatably connected. The transmission shaft can drive the movable shaft to rotate through the pulley mechanism, thereby driving the spray pipe to rotate forward and reverse.

[0011] Preferably, a spray pipe is fixed to the other end of the movable shaft, and the water pipe is connected to the spray pipe through the cavity in the movable shaft, and a spring is provided at the rotation point of the movable shaft and the water pipe, and the liquid in the water pipe can be transferred to the spray pipe through the cavity in the movable shaft.

[0012] Preferably, the cooling mechanism includes a fan blade fixedly mounted on an end of the connecting shaft away from the motor, and the space outside the fan blade is interconnected with one end of the air pipe, and an injection pipe is fixed to the other end of the air pipe, and the wind force generated by the rotation of the fan blade can be transmitted to the injection pipe through the air pipe.

[0013] Preferably, the air delivery pipe and the air jet pipe are connected, and the air jet pipe is arranged directly above the spray pipe. Wind can be transmitted to the air jet pipe through the air delivery pipe, thereby further cooling the air.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the circulating spray device of the evaporative air cooler can recycle and reuse excess water after the liquid is sprayed on the evaporative air cooler, thereby reducing the waste of water resources. In addition, when recycling water, impurities contained in the water can be intercepted to avoid clogging of the water flow channel. The specific contents are as follows:

[0015] 1. During the spraying process, excess liquid can fall on the water tank, then flow through the depression to the through groove, and then flow into the water tank after being filtered by the filter screen, so as to realize the recovery of the liquid for subsequent recycling;

[0016] Furthermore, the connecting shaft can drive the transmission shaft to rotate through two meshing gears, and the transmission shaft drives the cleaning brush to sweep over the filter to prevent it from being blocked by impurities intercepted by the filter, thereby ensuring the smoothness of the recovered liquid. When the lower gear is not meshed with the upper gear, the spring resilience can drive the transmission shaft and the cleaning brush to rotate in the other direction, and the transmission shaft can drive the movable shaft to rotate through the pulley mechanism, thereby driving the spray pipe to rotate forward and reverse, thereby expanding the spray range.

[0017] 2. The rotation of the connecting shaft can also drive the fan blades to rotate. The wind force generated in this way can be transmitted to the jet pipe through the air pipe, blowing cold air to the spray pipe while spraying liquid, thereby playing a cooling role, thereby improving the cooling effect of the evaporative air cooler.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-6 , the utility model provides the following technical solutions:

[0027] Example 1: In order to solve the problems existing in the prior art, this embodiment adopts the following technical scheme: a circulating spray device for an evaporative air cooler, comprising a water tank 1, a protective plate 2 being fixed at the upper edge of the water tank 1, and the upper surface of the water tank 1 being concave, a motor 3 being installed on the side of the water tank 1, and the output shaft of the motor 3 being connected to a connecting shaft 4, a turbine 5 being installed at one end of the connecting shaft 4 close to the motor 3, and the space outside the turbine 5 being interconnected with a water pipe 6; further comprising: the outer side of the connecting shaft 4 being interconnected with a cleaning mechanism through two meshing gears 7, and the cleaning mechanism being arranged above the water tank 1, and a through groove 10 for recovering liquid being opened at the concave portion of the water tank 1; the spraying mechanism and the cooling mechanism being both arranged above the water tank 1, and the height of the spraying mechanism being lower than that of the cooling mechanism.

[0028] The existing spraying device directly discharges the spray water after spraying the evaporative air cooler, causing waste. There is no structure to recover and recycle the excess liquid after spraying. Moreover, after the liquid is sprayed on the evaporative air cooler, it will carry some impurities and flow out, which is easy to cause blockage of drainage pipes and other structures. Figure 2-Figure 6As shown, the distribution range of the gear blocks 7 on the connecting shaft 4 is 1 / 2 of its circumference, and the cleaning mechanism includes a transmission shaft 8 with a bearing passing through the side of the water tank 1, and a spring is provided at the rotation point of the transmission shaft 8 and the water pipe 6; a cleaning brush 9 is provided on the outer side of the transmission shaft 8, and the bottom of the cleaning brush 9 is in contact with the surface of the filter 11, and the filter 11 is fixed on the inner side of the through groove 10; the spray mechanism includes a movable shaft 12 passing through the top of the water pipe 6, and one end of the movable shaft 12 is connected to the transmission shaft 8 through a pulley mechanism, and the movable shaft 12 and the water pipe 6 are rotatably connected; a spray pipe 13 is fixed to the other end of the movable shaft 12, and the water pipe 6 is connected to the spray pipe 13 through the cavity in the movable shaft 12, and a spring is provided at the rotation point of the movable shaft 12 and the water pipe 6; first, the evaporative air cooler is installed on the upper end surface of the water tank 1, and the motor 3 drives the turbine 5 to rotate through the connecting shaft 4, thereby spraying the liquid in the water tank 1 The liquid is drawn into the water delivery pipe 6 and then transferred to the spray pipe 13 through the cavity in the movable shaft 12, and finally sprayed onto the evaporative air cooler for cooling. During the spraying process, excess liquid can fall on the water storage tank 1, and then flow to the position of the through groove 10 through its depression, and flow into the water storage tank 1 through the filtration of the filter screen 11, so as to realize the recovery of the liquid for subsequent recycling. The connecting shaft 4 can drive the transmission shaft 8 to rotate through two meshing gears 7, and the transmission shaft 8 drives the cleaning brush 9 to sweep over the filter screen 11 to avoid clogging caused by impurities intercepted by the filter screen 11, thereby ensuring the smoothness of the recovered liquid. Since the tooth block distribution range of the gear 7 on the connecting shaft 4 is limited, when the lower gear 7 is not engaged with the upper gear 7, the spring resilience can drive the transmission shaft 8 and the cleaning brush 9 to rotate in the other direction, and the transmission shaft 8 can drive the movable shaft 12 to rotate through the pulley mechanism, thereby driving the spray pipe 13 to rotate forward and backward, thereby expanding the spray range.

Therefore, this embodiment adopts the following technical solutions, such as Figure 1-Figure 2 As shown, the cooling mechanism includes a fan blade 14 fixedly mounted on the end of the connecting shaft 4 away from the motor 3, and the space outside the fan blade 14 is communicated with one end of the air pipe 15, and an injection pipe 16 is fixed to the other end of the air pipe 15; the air pipe 15 and the injection pipe 16 are connected, and the injection pipe 16 is arranged directly above the spray pipe 13; the rotation of the connecting shaft 4 can also drive the fan blade 14 to rotate, so that the wind force generated can be transmitted to the injection pipe 16 through the air pipe 15, and cold air is blown toward the spray pipe 13 while spraying liquid, thereby playing a cooling role, thereby improving the cooling effect of the evaporative air cooler.
