Abstract
The invention provides a box-type single-stage direct-connecting high speed blower, and relates to the technical field of a blower. The blower comprises a motor, a fan which is arranged at a shaft end of the motor, and a silencing box body which is arranged outside the motor and the fan; and the blower is characterized by further comprising a baffle which is arranged in the silencing box body, and a cooling air duct which is fixedly connected with the baffle, wherein a box body air inlet is formed on the silencing box body corresponding to the cooling air duct, the diameter at two ends of the cooling air duct is greater than the diameter of the middle part of the cooling air duct, and the motor is placed at the middle part of the cooling air duct. The blower is reasonable in design, convenient and practical; the wind speed flowing through the motor casing is large, the radiation effect is good, and the motor works safely and stably.
Description
Technical field:
The present invention relates to the blower technical field, specifically box single-stage direct connection high-speed blower.
Background technique:
Single-stage air (magnetic) high-speed centrifugal blower has simple in structure, and volume is little, and is energy-efficient, and regulation range extensively waits outstanding advantages, is the direction of blower fan development.The raising with domestic equipment manufacture level of emerging in large numbers along with new technologies and materials, so that the stability of high-speed fan improves greatly, manufacture cost descends, and it can replace the traditional products such as most of low speed multistage centrifugal blower and roots blower, the steady pulsating movement free of air-flow, the energy-efficient cost that falls.The using scope of high-speed fan is more and more wider, has obtained gradually user's approval, and market prospects are wide.According to statistics, the electric power of China approximately 15% is consumed by blower fan, and high-speed blower is to promoting the blower fan technological progress, and high-end manufacturing industry domestic brand is established in energy-saving and emission-reduction, and is all significant.Box single-stage air of the prior art (magnetic) high-speed centrifugal blower, under naturally through-flow state, the wind speed on electric machine casing surface of flowing through on the electrical axis direction is little, and inhomogeneous, heat during machine operation is difficult in time all take away, cause electric machine temperature rise too high, the decline of exerting oneself, even burn.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of raising motor surface axial flow wind speed, thereby improve the cooling effect of motor, in the situation that cooling fan is not with in the motor end, heat when motor is worked is in time taken away, and guarantees the box single-stage direct connection high-speed blower of the work of blower long-term stability.
Technical problem to be solved by this invention adopts following technological scheme to realize:
Box single-stage direct connection high-speed blower, comprise motor, be installed in the blower fan of motor shaft end, be located at the noise reduction casing of motor and blower fan outside, it is characterized in that: also comprise the dividing plate that is located at the noise reduction box house, the cooling air duct that is fixedly connected with dividing plate, the position of corresponding cooling air duct is provided with the casing intake grill on the described noise reduction casing, the diameter at the two ends of described cooling air duct is greater than the diameter of centre, and motor places the centre of cooling air duct.
Described blower fan comprises intake grill and exhaust outlet, and air inlet is positioned at casing.
Described motor is fixed on the inside bottom of noise reduction casing by electric machine support, be positioned at the centre of cooling air duct.
On the described casing intake grill air intake filter is housed.
Described blower fan is fixed on the inside of noise reduction casing by fan supporter.
We know, within the specific limits along with the increase of the liquid speed of the heat exchanger surface of flowing through, can greatly improve the convection transfer rate of heat exchanger surface, increase exchange capability of heat.For this reason, we increase a cooling air duct between noise reduction casing and motor, the all gas that blower is carried, suck the noise reduction casing through outside air intake filter plate, high speed flow is crossed the housing outer surface of motor after the cooling air duct is collected, strengthen the convection heat exchange of electric machine casing, the heating value in the machine operation process has been taken away timely, guaranteed the work that high-speed electric expreess locomotive is safe and reliable.
The invention has the beneficial effects as follows: reasonable in design of the present invention, convenient and practical, electric machine casing axial flow wind speed is large, good heat dissipation effect, machine operation safety and stability.

Fig. 1 is master's TV structure schematic diagram of the present invention.
Fig. 2 is plan structure schematic diagram of the present invention.
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, 2, box single-stage direct connection high-speed blower, comprise motor 1, be installed in the blower fan 2 of motor 1 axle head, be located at the noise reduction casing 3 of motor 1 and blower fan 2 outsides, also comprise the dividing plate 4 that is located at noise reduction casing 3 inside, the cooling air duct 5 that is fixedly connected with dividing plate 4, the position of corresponding cooling air duct 5 is provided with casing intake grill 6 on the noise reduction casing 3.Blower fan 2 comprises intake grill 21 and exhaust outlet 22.Motor 1 is fixed on the inwall of noise reduction casing 3 by support 7.Air intake filter 8 is housed, entrained larger impurity in gas when air intake filter 8 can filter out air intake on the casing intake grill 6.The diameter at the two ends of cooling air duct 5 is greater than the diameter of centre, and motor 1 places in the middle of the cooling air duct 5, and blower fan 2 is fixed on the inwall of noise reduction casing 3 by fan supporter 8.
The present invention is according to the better principle of the larger convection heat exchange effect of airspeed, adopted the mode of motor 1 in the 3 inner vertical settings of noise reduction casing, gas is entered into the inside of noise reduction casing 3 by casing intake grill 6 low speed, flow through between the housing of cooling air duct 5 and motor 1 the gap and collected, the gas high speed flow is crossed the outer surface of the housing of motor 1, forced heat exchanging, thereby make whole heats that produces when motor 1 is worked of taking away, gas enters Sound Attenuator body 3 behind the terminal diffusion of cooling air duct 5 upper part, again become low velocity gas, sucked again the inside of blower fan 2 by the intake grill 21 of blower fan 2, do work through impeller, gas obtains pressure energy and becomes pressurized gas, is sent by the exhaust outlet 22 of blower fan 2.
The present invention also can be with motor 1 in the 2 inner horizontal settings of noise reduction casing, but the principle that the problem of its solution adopts is the same, belongs to same inventive concept.
Above demonstration and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
