Description
[technical field]
The utility model relates to a kind of ventilation and exhaust device, is specifically related to the dual-purpose variable air flow pipeline fan of a kind of ventilation smoke exhaust technical field.
[background technique]
Generally all need smoke-discharging and ventilating equipment as a sub-systems in city building or the small-sized confined space in modern times, be used for air exchange between the inner perhaps small-sized confined space of building and the external world, to keep building or small-sized air in closed space pure and fresh.
Existing fire-fighting ventilation equipment only can be used for overall situation ventilation, smoke evacuation; But for example the ventilation smoke exhaust effect is then relatively poor among a small circle in office, entertainment places box, the restaurant's box; And the low energy consumption of main exhaust equipment operational efficiency is big, wastes a large amount of electric energy and but can not get a desired effect.
A kind of pipe ventilated machine is exactly like above-mentioned a kind of technological scheme to the Chinese patent publication number for CN 101846091A discloses; This invention mainly is made up of housing, impeller, motor, motor frame, guide plate and terminal box; Motor is connected with impeller; Motor is fixed on the motor frame and is fixed in housing through guide plate, and terminal box is arranged on the housing.This invention has reduced cost of production through integrated design but in small-sized confined space, can't reach the actual desired effect, and this device can't be adjusted air quantity, blast simultaneously.
[model utility content]
In order to overcome the deficiency of existing technology, the utility model provides a kind of ventilation smoke exhaust dual-purpose variable air flow pipeline fan, and this device is fit to middle-size and small-size confined space air draft smoke evacuation, and equipment ventilation effect efficient height is energy-conservation simultaneously, has very strong practical effect.
The utility model technical problem to be solved is: how a kind of air draft fume extractor that is applicable to many small-sized confined spaces is provided; Can regulate and control simultaneously the novel fan of fan delivery, blast, when breaking out of fire, adjust to the smoke evacuation state automatically through the transmission of fire-fighting control signal; Simultaneously can be according to the dirty state stepping running of air; Fan performance optimum and environment are coincide, accomplish low-carbon economy, energy-conserving and environment-protective, and noise decreases also.
The technological scheme that the utility model adopted is: the dual-purpose variable air flow pipeline fan of ventilation smoke exhaust; It is characterized in that the speed change high-temperature electric machine is installed in the back cabinet outer end; Impeller adopts high temperature resistant iron plate to be stamped to form; Impeller is connected with high temperature variable speed electric motors, particularly axis, and impeller sleeve is connected with front housing, and the high temperature variable speed electric motors, particularly is connected with detection control apparatus through circuit.
The dual-purpose variable air flow pipeline fan of described ventilation smoke exhaust is characterized in that, comprises on the described detection control apparatus indoor air dirt degree detection device, and this device is connected with control gear.
After the dual-purpose variable air flow pipeline fan of ventilation smoke exhaust is installed energising; The air dirt degree of the automatic testing environment of detection control apparatus is controlled the speed change high-temperature electric machine then makes it reach the working state that adapts to environment facies; The work of high temperature variable speed electric motors, particularly makes the impeller operation that is connected with its axis, and indoor air flow is discharged to the rectangle exhaust outlet through the rectangle intake grill, is discharged on the main gas exhaust duct; To reach the purpose with the outside air exchange, make indoor air pure and fresh.
The utility model beneficial effect: this device is applicable to many small-sized confined space air draft smoke evacuations, and can be according to detecting the automatic control motor running speed to reach the working state that blower fan and environment facies adapt to, and energy-conserving and environment-protective are simply effective, have very strong practical effect.
For making characteristic and the technology contents of further understanding the utility model, see the utility model accompanying drawing and mode of execution for details, yet appended graphic only for reference and explanation usefulness is not to be that the utility model is limited.

Figure (2) is the utility model A-A ' portion view;
Figure (3) is the utility model mounting structure figure;
Figure (4) is the utility model blade wheel structure figure;
Figure (5) is the utility model impeller motor long splice composition;
Among the figure, the 101-front housing; The 102-back cabinet; The 103-spiral case; 104-high temperature variable speed electric motors, particularly; The 105-impeller; 106-installs valve; 107-rectangle intake grill; 108-rectangle exhaust outlet; The 109-impeller sleeve; The 110-terminal box; The 111-detection control apparatus.
[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
The dual-purpose variable air flow pipeline fan of ventilation smoke exhaust its by the 101-front housing; The 102-back cabinet; The 103-spiral case; 104-high temperature variable speed electric motors, particularly; The 105-impeller; 106-installs valve; 107-rectangle intake grill; 108-rectangle exhaust outlet; The 109-impeller sleeve; The 110-terminal box; The 111-detection control apparatus is formed.
Like Fig. 1-shown in Figure 5: the dual-purpose variable air flow pipeline fan of ventilation smoke exhaust high temperature variable speed electric motors, particularly 104; Be installed in back cabinet 102 outer ends, impeller 105 adopts high temperature to be stamped to form, and impeller 105 is connected with high temperature variable speed electric motors, particularly 104 axis; Impeller sleeve 109 is connected with front housing 101; After high temperature variable speed electric motors, particularly 104 was switched on through circuit and detection control apparatus 111 connections, the air dirt degree of detection control apparatus 111 automatic testing environments is controlled speed change high-temperature electric machine 104 then made it reach the working state that adapts to environment facies, and 104 work of high temperature variable speed electric motors, particularly make impeller 105 runnings that are connected with its axis; Indoor air flow is discharged to rectangle exhaust outlet 108 through rectangle intake grill 107; Be discharged on the main gas exhaust duct,, make indoor air pure and fresh to reach the purpose with the outside air exchange.
This device is applicable to many small-sized confined space air draft smoke evacuations, and can be according to detecting the automatic control motor running speed to reach the working state that blower fan and environment facies adapt to, and energy-conserving and environment-protective are simply effective, have very strong practical effect.
Yet the preferable feasible embodiment of above-mentioned only the utility model, non-so limitation the utility model protection domain is done various distortion or is applied mechanically all within this technological scheme protection domain according to the foregoing description.
