Description
Technical field
The utility model relates to field of ventilation equipment, particularly relates to a kind of centrifugal blower.
Background technique
Centrifugal blower is the mechanical energy relying on input, and improve gas pressure and to supply gas side by side the machinery of body, it is a kind of driven fluid machinery.Centrifugal blower is widely used in factory, mine, tunnel, cooling tower, vehicle, the ventilation of boats and ships and building, dust discharge and cooling; The ventilation of boiler and industrial furnace and air inducing; Cooling in the apparatus of air conditioning and domestic electric appliance and ventilation; The oven dry of cereal and selecting and recommending; The inflation of wind-tunnel wind regime and Hovercraft and propelling etc.Centrifugal fan is made up of casing, main shaft, impeller, bearing transmission mechanism and motor etc., wherein impeller is as the most serious parts of loss, often need to change, blade on the impeller part that loss is the most serious especially, because the various piece on existing impeller is all for being welded and fixed, in time there is loss in one of them parts, whole impeller is needed to change, due to the many wear-resistants of connection shaft, and it is more expensive to fake, often after blade loss, connection shaft is also comparatively intact, and during replacing, waste is serious.
Model utility content
The utility model provides a kind of centrifugal blower, rational in infrastructure, and shaft member is detachable, and in order to solve technique scheme, the utility model adopts following technological scheme:
A kind of centrifugal blower, comprise spiral case, described spiral case comprises exhaust outlet and intake grill, described intake grill is arranged on side plate, described side plate is fixed on the side of spiral case by link, described exhaust outlet is arranged on the tail end of spiral case, described exhaust outlet is provided with extension shell, and described extension shell edge is provided with aperture; Be fixedly connected with organic frame below described spiral case, described rack level is arranged, and the upper-end surface of the other end of described frame is connected with motor; Be provided with impeller in described spiral case, be provided with coupling shaft in described impeller, described coupling shaft and impeller are detachable connection, and described coupling shaft is connected with motor by belt wheel.
A kind of centrifugal blower that the utility model provides, preferably, described link is bolt, and described link has 6, and is evenly distributed on the whole body of side plate.
A kind of centrifugal blower that the utility model provides, preferably, described extension shell is provided with temperature testing device.
A kind of centrifugal blower that the utility model provides, preferably, described frame is made up of with crossbeam side plate, and described side plate is all shaped steel with crossbeam.
Advantage of the present utility model and beneficial effect are: the ventilator that the utility model provides, compact structure, performance curve is smooth, change shaft member in the past and fix the Placement of welding with impeller, connection shaft is set to movable and connects, when the blade on impeller occurs that wearing and tearing need to change time, do not need to change whole parts, shaft member is remained, saves material, improve utilization ratio;
Meanwhile, at exhaust outlet, place is provided with temperature-detecting device, when blower interior temperature is too high; other dangerous situations such as the blast of ventilator may be caused, after being provided with temperature-detecting device, when temperature arrives dangerous values; alarm work, notifies that workman comes to overhaul or shuts down.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, preferred implementation of the present utility model is preferably described, wherein,
Fig. 1 is the schematic diagram of a kind of centrifugal blower of the utility model.
Embodiment
Be described further with reference to the embodiment of Fig. 1 to a kind of centrifugal blower of the utility model:
A kind of centrifugal blower, comprise spiral case 1, described spiral case 1 comprises exhaust outlet 5 and intake grill 4, described intake grill 4 is arranged on side plate 6, described side plate 6 is fixed on the side of spiral case 1 by link 8, described exhaust outlet 5 is arranged on the tail end of spiral case 1, and described exhaust outlet 5 is provided with and extends shell 51, described extension shell 51 edge is provided with aperture; Be fixedly connected with organic frame 7 below described spiral case 1, described frame 7 is horizontally disposed with, and the upper-end surface of the other end of described frame 7 is connected with motor 3; Be provided with impeller 2 in described spiral case 1, be provided with coupling shaft 21 in described impeller 2, described coupling shaft 21 is connected for detachable with impeller 2, and described coupling shaft 21 is connected with motor 3 by belt wheel 9.
Preferably, described link 8 is bolt, described link 8 has 6, and being evenly distributed on the whole body of side plate 6, M8 selected by bolt, and bolt is arranged with resilient pad, shake the loss brought when reducing fan operation and loosen, the fastening force that 6 bolts provide is enough to side plate 6 to be fixed on spiral case 1, simultaneously for convenience detach, reduces the time of dismounting.
In addition, described extension shell 51 is provided with temperature testing device, this temperature testing device is electrically connected with alarm buzzer, after the wind-warm syndrome on exhaust outlet 5 reaches appointment numerical value, temperature testing device detects this temperature, then sends signal, receive this signal by alarm buzzer and give the alarm, on-call maintenance personnel come to overhaul, and this alarm buzzer can be buzzer or is arranged on computer end, is monitored by professional.
Described frame is made up of with beam welding side plate, and described side plate is all shaped steel with crossbeam, and performance is good, and intensity is large, provides shock-absorbing function to a certain extent simultaneously.
In addition, the position of described exhaust outlet 4 represents with its angle, and can be 0 degree, 45 degree, 135 degree, 180 degree or 225 degree etc., usually select 0 degree, namely the position of exhaust outlet 4 be arranged upward.
Simultaneously, described impeller is circular arc, described impeller is welded with blade, and described blade is circular arc, and air quantity is stablized, stable performance, impeller and blade all adopt 16Mn steel making, through dynamic balance calibration after impeller welding is shaping, therefore operate steadily reliable, there are higher intensity and wear resistance, long service life.
