Abstract
The utility model relates to an extra-thin inducing blower, which is a device suitable for the ventilation of an underground garage and is composed of a silencing outer shell, an impeller, a motor, a current collector, a diffuser, a flexible nozzle, an air inlet, a spiral shell, a support bracket and a current dividing device. The bottom part of the silencing outer shell is provided with a rectangular hole welded with the air inlet. The top part is riveted with the flexible nozzle. The diffuser is positioned on the upper part of the silencing outer shell. The lower surface of the diffuser and the outlet of the spiral shell are punched by a galvanized board and are riveted to be shaped. The impeller is directly connected with the motor. The motor is connected and fixed with the current collector and the spiral shell by the support bracket. The diffuser is provided with the flow divider. The utility model has the maximum advantage of little space occupation. The utility model has a flexibly system and can realize optimal air current distribution. Fresh air can be induced to the entire space to obtain ventilating effects of high efficiency and economy. The utility model is a necessary optimal choice of the ventilation of an underground parking lot.
Description
Technical field:
The utility model relates to a kind of Induced fan, particularly a kind of ultrathin Induced fan of suitable underground parking garage ventilation usefulness belongs to the fluid machinery technical field.
Background technique:
Traditional underground parking garage ventilates to all adopting and arrange low speed airduct air supplying and exhausting system in the storehouse, and its maximum shortcoming is: the airduct cross-section size is bigger, and gas tends to accumulate in the place, dead angle away from air draught; The garage clear height is generally lower in addition, adopts the low speed airduct that constriction is arranged; Installation workload is big, invests higher; The operating cost height.And the building that has since itself characteristics airduct can't install at all.
The model utility content:
For deficiency and the defective that overcomes prior art, jet induced draft theory in the utility model utilization aerodynamics theory designs a kind of ultrathin Induced fan.With the inducing properties of a small amount of high velocity jet air-flow, drive static air effectively on every side, and reach the purpose of air ventilation.Under the condition of no airduct, the central speed of jet-stream wind is lighted gradually by outlet and is reduced, and the big more influence distance of jet-stream wind that then is subjected to of the central speed of outlet is far away more; The width of jet-stream wind increases gradually with the distance of spraying simultaneously, makes enlarged gradually by its scope that influences.According to the size in required ventilation place, many ultra-thin shape Induced fan systems can be installed, in the mode of relay the operational site is effectively ventilated.
The utility model mainly comprises parts such as noise elimination shell, impeller, motor, slip ring, Diffuser, flexible nozzle, intake grill, spiral case, support and shunt.The noise elimination shell is a square box that is made of double Shell, filling noise elimination cotton in the middle of the double Shell, and the noise elimination outer casing bottom has rectangular hole and intake grill welding; Noise elimination cover top portion and flexible nozzle riveted joint.Diffuser is positioned at the noise elimination shell upper, below the Diffuser and the outlet of spiral case rivet shaping again with the galvanized sheet punching press.The ring slip ring is equipped with in the inlet of spiral case, impeller is a centrifugal multi-blade impeller, directly is connected with motor, and the housing of motor is connected with support one end with nut, the other end of support connects with the same slip ring of nut, spiral case and is fixing, and shunt is housed in the Diffuser.
Air-flow is entered in the noise elimination shell by intake grill, by slip ring enter impeller, the centrifugal action downstream that produces when impeller rotates enters spiral case, the Diffuser of flowing through, and is shunted by shunt in Diffuser again and sends into each flexible nozzle, high pressure draught is sprayed.The noise elimination shell can reduce about noise 5db (A); Flexible nozzle can arbitrarily be adjusted jet direction according to air-conditioning requirement.
Great advantage of the present utility model is to take up room for a short time, and the system design flexible arrangement can realize best indoor general mood stream tissue, the outdoor new wind of sending into can be induced to whole space, reaches the ventilation effect of high-efficiency and economic.Become the necessary optimal selection of underground parking ventilation.
Description of drawings and mode of execution thereof:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1. be ultra-thin shape Induced fan structural principle plan view
Fig. 2. be ultra-thin shape Induced fan structural principle right elevation
As shown in Figure 1 and Figure 2, the utility model mainly comprises noise elimination shell 1, impeller 2, motor 3, slip ring 4, Diffuser 5, flexible nozzle 6, intake grill 7, spiral case 8, support 9 and shunt 10.Noise elimination shell 1 is a square box that is made of double Shell, and filling is eliminated the noise cotton in the middle of the double Shell.Noise elimination shell 1 bottom has rectangular hole and intake grill 7 welding; Noise elimination shell 1 top and flexible nozzle 6 riveted joints (quantity of flexible nozzle 6 is changeable as required, and the utility model is provided with 3).Diffuser 5 is positioned at noise elimination shell 1 top, and Diffuser 5 outlets following and spiral case 8 are riveted shaping again with the galvanized sheet punching press.Ring slip ring 4 is equipped with in the inlet of spiral case 8, impeller 2 is centrifugal multi-blade impellers, directly be connected with motor 3, the housing of motor 3 is connected with support 9 one ends with nut, the other end of support 9 connects with slip ring 4, spiral case 8 with nut and is fixing, impeller 2 can freely be rotated in spiral case 8, shunt 10 is housed in the Diffuser 5.
Air-flow is entered in the noise elimination shell 1 by intake grill 7, by slip ring 4 enter impeller 2, the centrifugal action downstream that produces when impeller 2 rotation enters spiral case 8, the Diffuser 5 of flowing through, in Diffuser 5, shunt again and send into each flexible nozzle 6, high pressure draught is sprayed by shunt 10.Noise elimination shell 1 can reduce about noise 5db (A); Flexible nozzle 6 can arbitrarily be adjusted jet direction according to air-conditioning requirement.
