Description

Technical Field

[0001] The utility model relates to the technical field of spray evaporation, and particularly relates to a spraying mechanism. Background Art

[0002] A cooling tower is a chemical engineering device mainly used to reduce the water temperature by using air as a coolant. For an air-conditioning cooling tower, it usually disperses a large amount of hot water generated by a central air conditioner through the cooling tower, and uses the direct heat transfer of air flow and the conversion of liquid water into gas to absorb a large amount of heat, which is then carried away by the atmosphere, so that the water temperature is reduced and the water is recycled.

[0003] Generally, a spraying mechanism is arranged at the bottom of a cooling tower, and water is sprayed to the bottom of the cooling tower through a spray evaporation head, so that after the water mist contacts the high-temperature part at the bottom of the cooling tower, the water mist evaporates. Since the water mist absorbs heat during the evaporation process, it can cool the bottom of the cooling tower. However, the traditional spray head can only spray water mist in one direction, which not only has a small working area, but also causes uneven cooling of the cooling tower, affecting the heat dissipation effect of the cooling tower in the long run, and further affecting the working efficiency of the air cooling.

[0034] Embodiment 1

[0035] Referring to Figures 1 to 4 As shown, in the first embodiment of the present utility model, a spraying mechanism is provided. This device includes a cooling element 100, which includes a fixing plate 101 and a spraying assembly 102 arranged on the fixing plate 101. By adjusting the spraying assembly 102, the effect of cooling the cooling tower 300 is achieved; and,

[0036] A rotating element 200, which includes a limiting plate 201 connected to the outer wall of the middle part of the fixing plate 101, an electric roller 202 rotatably arranged inside the limiting plate 201, and a transmission assembly 203 arranged on the fixing plate 101. The limiting plates 201 are arranged in an annular array on the side wall of the fixing plate 101, and the size of the electric roller 202 is adapted to the size inside the limiting plate 201, increasing the spraying area of the spraying assembly 102 on the cooling tower 300.

[0037] During the use process, first, the operator connects the water pipe to the cooling element 100, so that the atomizing nozzle 102e arranged inside 100 starts to spray water mist towards the bottom of the cooling tower 300. Subsequently, the operator adjusts the rotating element 200, so that the rotating element 200 drives the cooling element 100 to rotate, and the atomizing nozzle 102e arranged inside the cooling element 100 rotates synchronously, and sprays and cools the cooling tower 300. By rotating the cooling element 100 to cool the cooling tower 300, the cooling area of the cooling tower 300 is increased, and the cooling efficiency is improved.

[0038] Embodiment 2

[0039] Referring to Figures 1 to 5As shown, this is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the spraying assembly 102 includes a first diversion pipe 102a rotatably connected inside the fixing plate 101 in a linear array arrangement. The first diversion pipe 102a penetrates and rotates inside the fixing plate 101, circular baffles 102b symmetrically connected to the outer wall of the first diversion pipe 102a, a water pipe joint 102c connected to the top end of the first diversion pipe 102a, a second diversion pipe 102d connected to the top end of the first diversion pipe 102a away from the water pipe joint 102c, and atomizing nozzles 102e symmetrically connected to the side walls of the second diversion pipe 102d away from the first diversion pipe 102a. The water pipe joint 102c, the first diversion pipe 102a, and the second diversion pipe 102d are all connected and arranged in communication with the atomizing nozzles 102e, increasing the spraying range of the spraying assembly 102. And the materials of the first diversion pipe 102a and the second diversion pipe 102d are both steel products.

[0040] Furthermore, the transmission assembly 203 includes a gear 203a connected to one end of the first diversion pipe 102a away from the atomizing nozzle 102e, and a toothed belt 203b drivingly connected between the gears 203a. The size of the gear 203a is adapted to the size of the toothed belt 203b, achieving the effect of uniformly cooling the cooling tower 300 by the spraying assembly 102.

[0041] During use, first, the operator connects the water pipe joint 102c to an external water pipe, so that the external water flow enters the inside of the water pipe joint 102c through the external water pipe, then enters the inside of the first diversion pipe 102a through the water pipe joint 102c, then enters the inside of the second diversion pipe 102d through the first diversion pipe 102a, and finally is sprayed towards the bottom of the cooling tower 300 through the atomizing nozzles 102e; (The atomizing nozzles 102e usually have a pressurizing system, such as a manual pump, an electric pump, or a compressed air tank. This system is responsible for increasing the pressure of the liquid so that it can be sprayed out at a high speed through the nozzle. The atomizing nozzles 102e squeeze the liquid into the nozzle through the internal pressure. The high-speed flowing liquid impacts on the iron sheet inside the nozzle and rebounds to form fine liquid droplets. By controlling the internal pressure and the nozzle structure, atomized particles with a diameter of about 15 - 60 microns can be formed. Due to the special design of the nozzle, a fan-shaped or circular spray shape can be generated, and the coverage range is directly related to the pressure).

[0042] When the atomizing nozzle 102e starts to spray water mist onto the cooling tower 300, the operator then controls the electric roller 202 to rotate inside the limit plate 201 (the electric roller 202 usually uses a motor as the driving source, and the power transmission of the electric roller 202 depends on the coordinated work among the motor, the speed reducer, and the roller body. The motor generates rotational power, and through the speed reduction effect of the speed reducer, the power with high speed and low torque is converted into the power with low speed and high torque, so as to more effectively drive the roller body to rotate), so that the electric roller 202 drives the first diversion pipe 102a arranged in the middle of the fixing plate 101 to rotate synchronously, so that the first diversion pipe 102a drives the two atomizing nozzles 102e to rotate synchronously through the second diversion pipe 102d, so that the atomizing nozzles 102e spray and cool the bottom of the cooling tower 300 by rotating. At the same time, when the cooling element 100 arranged in the middle of the fixing plate 101 rotates, the first diversion pipe 102a arranged in the middle of the fixing plate 101 drives the gear 203a to rotate synchronously, so that the gear 203a drives the first diversion pipes 102a arranged at the upper and lower ends of the fixing plate 101 to rotate synchronously through the toothed belt 203b. Furthermore, multiple groups of atomizing nozzles 102e arranged on the fixing plate 101 spray and cool the cooling tower 300 synchronously in a rotating manner, and the cooling tower 300 is cooled by the atomizing nozzles 102e rotating. This not only increases the spraying area of the atomizing nozzles 102e, but also ensures the uniformity of the temperature reduction at the bottom of the cooling tower 300, achieving the effect of uniform temperature reduction.

[0043] The remaining structures are the same as those in Embodiment 1.

[0044] Embodiment 3

[0045] Referring to Figures 5 to 8 As shown, this is the third embodiment of the present invention. This embodiment provides a cooling tower: including a cooling tower 300, a first annular plate 301 is connected to the bottom of the cooling tower 300, and a second annular plate 302 is connected to the bottom of the cooling tower 300.

[0046] Furthermore, the sizes of the first annular plate 301 and the second annular plate 302 are both adapted to the bottom size of the cooling tower 300, and can be effectively fixed to the cooling tower 300.

[0047] Furthermore, the fixing plate 101 is connected between the first annular plate 301 and the second annular plate 302 in an annular array, realizing multi-directional temperature reduction treatment for the bottom of the cooling tower 300.

[0048] During use, the bottom of the cooling tower 300 is evenly sprayed and cooled by the fixing plate 101 arranged in an inclined annular array at 30 to 75 degrees between the first annular plate 301 and the second annular plate 302, avoiding damage to the bottom of the cooling tower 300 due to excessive temperature, and thus improving the working efficiency of the cooling tower 300.

[0049] The remaining structure is the same as that of Embodiment 2.
