Abstract
The utility model discloses an improved central laryngeal of cooling tower, comprising a straight laryngeal and a water separating pipe communicated thereof. The water separating pipe and the straight laryngeal are connected to form a Y-shaped structure. The water separating pipe can also be communicated with the straight laryngeal through a tee connecting joint to form the Y-shaped structure. The Y-shaped central laryngeal is connected to a motor installation frame above the central laryngeal, which is used to support the weight of the motor and a fan. The utility model is notably characterized in that the central laryngeal is connected to the motor installation frame above to support the weight of the motor and the fan, therefore reducing the bearing load of the motor installation frame, thus saving materials. Additionally, the water separating pipe and the straight laryngeal are connected to form the Y-shaped central laryngeal structure, which largely reduces the number of the tee connecting joints and elbows, making the water flow of the central laryngeal more fluent, therefore reducing the resistance of the water flow, meanwhile reducing the load of the water pump and strengthening the durability thereof.

The specific embodiment
Embodiment one:
Shown in Fig. 2 (a), the described center of present embodiment larynx comprises bent larynx 10, straight larynx 11, and the distributive pipe 12 that is communicated with straight larynx 11, and its distributive pipe 12 is connected to form Y shape structure with straight larynx 11 by flange 14.This Y shape center larynx is connected with the motor installing rack of its top, plays the effect of supporting motor and blower fan weight, therefore can alleviate the load-bearing load of motor installing rack, thereby save materials.The center larynx of this Y shape structure can also significantly reduce the T shape threeway connector in the larynx of traditional center and the number of 90 ° of elbows, makes the current in the larynx of center more smooth and easy, reduces the resistance of current, has reduced the load of water pump.
The applicant had once applied for a kind of application for a patent for invention of improved cooling tower housing structure on November 7th, 2005, and open on April 19th, 2006, publication number CN 1760618A.Below be example just with this patent application, introduce Y shape described in the utility model center larynx in detail in the application in the cross flow cooling tower: shown in Fig. 4,5, the bent larynx 10 of above-mentioned Y shape center larynx is connected with water inlet pipe, distributive pipe 12 is communicated with the watering dish, the two end supports of motor installing rack 30 is in the groove shoulder of body of the tower both sides glass fibre side plate 31, fixedlys connected with the distributive pipe 12 of center larynx in the middle part of motor installing rack.As shown in Figure 5, distributive pipe 12 is provided with fin 16 along tube wall, and this fin 16 is located by connecting by angle bar 17 and motor installing rack 30, in order to make fin 16 and angle bar 17 firm being connected, can sandwich a band iron (not shown) in the fin of its junction.
Different with the mounting means of traditional cross flow cooling tower, as shown in Figure 3, the motor of traditional cooling tower is that external is installed, and promptly transmission systems such as motor installing rack and motor are installed in the top of air duct.Present embodiment utilizes Y shape center larynx support motor installing rack 30, and the weight of transmission systems such as blower fan, motor and the power that produced are directly guided to ground, just can simplify the fiberboard thickness of motor installing rack and air duct, saves material.And built-in motor is installed on the below of blower fan, and the position is lower, and center of gravity descends, and can reduce vibration, can reduce the mechanical noise of motor and transmission system simultaneously effectively.In addition, built-in motor has bigger air-out area than outboard motor, and air-out is more even, and wind speed is slower, and energy consumption is lower, and noise is lower.
