Abstract
The utility model provides a fan with a filter box, which includes a dextral fan and a sinistral fan which are mutually arranged; the air inlets of the fan are respectively connected with the two air outlets of the filter box which can intake air in large area by soft connection. The middle parts of the two sides of the body of the filter box are respectively provided with a differential gauge; a filter screen gate which is conveniently dismounted is arranged at the front part of the two sides of the body of the filter box. The fan with a filter box has the effects that the improvement of the structure leads the filter area of the fan to be enlarged by more than 20 times compared with the area of the air inlet of the fan; the filter screen can be changed during when a device runs. The use situation of the filter screen is judged according to the reading numbers of the pointers of the differential gauges. The period for changing the filter screen can be prolonged; the changing and cleaning modes are convenient. As the indication of a watch hand leads an air medium and the fan to be scientifically controlled, the structure form of the fan is broadly applied to the outdoor occasions which need roughing efficiency filtering, such as the matching use of the decarbolizing device of an electric power plant.
Description
Technical field
The utility model relates to a kind of blower fan, particularly a kind of blower fan with Rose Box.
Background technique
Generally, when the logical atmosphere of air inlet is not taken over net, should add one deck filter screen, to play the effect of primarily efficient filter and safety.Because the inlet-duct area of blower fan is smaller, so filter area is also very little.If this blower fan uses on the desulphurization plant of power plant, because the Environmental Conditions condition is relatively poor, filter screen stops up soon and causes pipe network not normal, and needs shutdown to change, and influences the normal operation of desulphurization plant.Applying unit is badly in need of the filtration blower fan of large size air intake, is the task of top priority.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the technical solution adopted in the utility model provides a kind of blower fan with Rose Box, include the dextrorotation and the left-handed two typhoon machines that are symmetrically set, air inlet is by being flexible coupling, be connected on the exhaust outlet of Rose Box of large size air intake, casing two middle side parts at Rose Box are equipped with differential pressure gauge respectively, the casing front part sides of Rose Box be provided with can easy disassembly the filter screen door.
Effect of the present utility model is the improvement of this structure, and the filter area of blower fan is strengthened, and is twenties times of air inlet area, replaceable cleaning and filtering net when equipment operation.According to the total indicator reading of differential manometer, judge the use condition of filter screen.Prolong the replacing cleaning and filtering net cycle, made things convenient for replacing and cleaning way.Owing to be that the indicator indication can science be controlled air dielectric and fan operation.This blower fan structure form extensively is used in the occasion outdoor, that the primarily efficient filter requirement is arranged, as the supporting use of power plant desulfurization equipment.

Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated the blower fan structure of band Rose Box of the present utility model.
The blower fan structure of band Rose Box of the present utility model, include shape, dextrorotation blower fan 4 that is symmetrically set and left-handed blower fan 5 that structure is identical, as shown in Figure 1, 2, 3, the intake grill 7 of dextrorotation blower fan 4 and left-handed blower fan 58 is connected on two exhaust outlets 6 of Rose Box 1 of large size air intake by being flexible coupling respectively, casing both sides at the Rose Box 1 of large size air intake are respectively equipped with differential pressure gauge 2, on the casing rear portion of Rose Box 1, be provided with can easy disassembly filter screen door 3.Rose Box and two typhoon machines are installed on the common base.
Blower fan filtering area originally is exactly the size of air inlet, and diameter range is ￠ 180-￠ 250mm, and areal extent is 0.0254-0.049m
2, and the blower fan filtering case minimum of band Rose Box to be of a size of 600 X 1000mm areas are 0.6m
2Be about 20 times of air inlet area.
The blower fan of band Rose Box of the present utility model is used for the inlet box seal fan machine and the diffusion barrel seal fan of BUF project.Because differential pressure gauge is the indicator indication, make the control and management of air dielectric and fan operation energy science.The filter screen door 3 that the casing front side of Rose Box 1 is provided with, the replacing of easy disassembly filter screen and cleaning.In actual the use, observe the total indicator reading of differential pressure gauge 2 at any time, judge the use condition of filter screen, in the time of near differential pressure gauge 2 pointers point to setting value, filter screen is changed cleaning, guarantee the normal operation of pipe network system.Prolong and change the cleaning and filtering net cycle, increase work efficiency, reduce user cost.
At present, be Howden Wua Engineering Co., Ltd, the plane No. of the blower fan of this band Rose Box that forms a complete production network has 4,4.3,4.6,5.6, HDK5.6, all is used in the power plant desulfurization equipment.In the actual using process, two typhoon machines can turn round simultaneously, perhaps typhoon machine running, and another is standby; Also can only be equipped with a typhoon machine band Rose Box as required.
This structural type blower fan also can be used on the occasion of primarily efficient filter requirement, and medium temperature generally is no more than 50 ℃, the highlyest is no more than 80 ℃, and dust loading is no more than 150mg/m
3This blower fan is made the aluminium impeller, and supporting anti-explosion motor just can be used in the occasion of requirement of explosion proof.
