Abstract
The utility model discloses a draught fan protection device. The draught fan protection device comprises a draught fan, wherein an outlet of the draught fan is provided with an air flue in a spot welding mode. The air flue extends to the outside, is provided with a supporting frame and is made of iron sheets. Because the air flue is connected with the outlet of the draught fan, extends to the outside and leads the outlet of the draught fan to the outside, when the outlet of the draught fan is exposed indoors, blocking of the outlet of the draught fan caused by absorbing various kinds of impurities is avoided, and normal operation of the draught fan is guaranteed. The draught fan protection device is simple in structure and low in cost.
Description
Technical field
The utility model relates to a kind of blower fan protective gear.
Background technique
Blower fan is widely used in the ventilation and the smoke evacuation of fire-fighting high temperature in places such as tunnel, underground parking garage, senior civil building, metallurgy, factories and miness; Blower is a kind of of blower fan, and blower mainly is made up of following six parts: motor, air filter, blower body, air chamber, base (fuel tank of holding concurrently), oil dripping mouth.Blower leans on the rotor eccentricity running of biasing in the cylinder, and makes the volume-variation between the blade in the rotor that air is sucked, compresses, spues.The on-stream pressure difference of blower of utilizing is delivered to the oil dripping mouth with lubricant oil automatically, splashes in the cylinder to reduce friction and noise, can keep that gas does not reflux in the cylinder simultaneously, and this type of blower is called the sliding vane blower again.The blower fed sheet of a media is main with clean air, cleaning coal gas, sulfur dioxide and other inert gases; Also can produce as required and carry other inflammable, explosive, easy erosions, poisonous and special gas, thereby can be adaptable across each industrial departments such as metallurgy, chemical industry, chemical fertilizer, petrochemical industry, food, building materials, oil, mine, weaving, gas station, strength conveying, sewage treatments.The outlet of traditional blower fan only is provided with the layer of protecting net, and other protective gears are not set, in some use occasion; Long-term use will cause the outlet phenomenon of blocking; Such as in the more place of greasy dirt, on catch net, can form thick grease, influenced the normal use of blower fan.
The model utility content
The purpose of the utility model is to address the above problem, and a kind of blower fan protective gear is provided, and it can play a good protection to the outlet of blower fan, blower fan outlet phenomenon of blocking can not occur, has simple in structure, lower-cost advantage.
The purpose of the utility model is to realize through following technological scheme:
A kind of blower fan protective gear comprises blower fan, and said blower fan outlet is connected with the air channel of adopting iron sheet to make, and said air channel passes to outdoor.
Said air channel is provided with support.
Said air channel adopts spot welding to be connected with the blower fan outlet port.
The beneficial effect of the utility model is: through connecting the air channel in the blower fan outlet, the air channel passes to outdoor, and its outlet with blower fan has been guided to outdoor; Avoided outlet to be exposed to when indoor; Various impurity are adsorbed in the outlet port, cause exporting phenomenon of blocking, and then influence the proper functioning of blower fan; The contrast existing technology, this device has simple in structure, lower-cost advantage.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the described a kind of blower fan protective gear of the utility model.
Among the figure:
1, blower fan; 11, blower fan outlet; 2, air channel; 3, support.
Embodiment
Among the embodiment as shown in Figure 1, the described a kind of blower fan protective gear of the utility model comprises blower fan 1, and 11 of blower fan outlets are welded with air channel 2, and air channel 2 passes to outdoor, and air channel 2 is provided with support 3, and air channel 2 adopts iron sheet to make.Through export 11 connection air channels 2 at blower fan; Air channel 2 passes to outdoor, and its outlet with blower fan 1 has been guided to outdoor, has avoided blower fan outlet 11 to be exposed to when indoor; Adsorb various impurity; Cause blower fan to export 11 phenomenon of blocking, and then influence the proper functioning of blower fan 1, this device has simple in structure, lower-cost advantage.
