Description
Technical field
This utility model relates to a kind of humidity discharging centrifugal blower.
Background technology
Centrifugal blower is dependent on the mechanical energy of input, improve gas pressure to supply gas side by side the machinery of body, it is a kind of driven fluid machinery, the principle of centrifugal blower is the principle being converted to potential energy according to kinetic energy, gas is accelerated by the impeller utilizing high speed rotating, then slow down, change the flow direction, make kinetic energy be converted into potential energy.
Some are for getting rid of the centrifugal blower of dust, waste gas, due to its exhaust passage, to extend the pipeline in workshop longer, condensed fluid can be produced, and this partial condensation liquid can be back in the spiral case of centrifugal blower, on the one hand the condensed fluid of thickness easily forms a large amount of dirty on spiral case inwall, dirty is killed to fall behind by wind and is rolled on impeller to make impeller failure, and on the other hand condensed fluid can be back on impeller or motor so that motor damage.
Utility model content
This utility model is for deficiency of the prior art, it is provided that a kind of humidity discharging centrifugal blower, and it can stop the condensed fluid produced on pipeline to be back on impeller or motor, and absorbs this partial condensation liquid of erasing, it is to avoid blower fan damages because of condensed fluid backflow.
For solving above-mentioned technical problem, this utility model is addressed by following technical proposals: a kind of humidity discharging centrifugal blower, including spiral case and impeller, described impeller is driven by motor, there is on described spiral case air inlet and air outlet, some groups of humidity discharging assemblies it are provided with on described spiral case inwall, described humidity discharging assembly includes the fixed block being sequentially connected with, a number spring and brush board, described fixed block is fixedly installed on described spiral case inwall, described brush board is slidably connected on described spiral case inwall, described spiral case inwall is further fixedly arranged on support cylinder, it is rotatably connected to sleeve on described support cylinder, some blades it are provided with on described sleeve outer wall, it is provided with stay cord between described blade and corresponding described brush board, when after described sleeve rotating, described stay cord pulls described brush board toward described fixed block one side shifting.
During use, driven by motor impeller rotates, and the wind of generation is to blade, sleeve is rotated along supporting cylinder, and after rotation, brush board is pulled by stay cord toward fixed block side, a now spring contraction, during impeller persistently produces wind, a spring shrinks all the time, only move left and right in the least scope after namely brush board is pulled by stay cord, after motor quits work, losing the effect of wind-force, a spring is upheld, promote brush board side shifting outward, brush the condensed water being back in spiral case.
In technique scheme, it is preferred that described brush board is provided with spongy layer on the side of described spiral case inwall.
In technique scheme, it is preferred that be provided with water-absorbing sponge on described brush board.
In technique scheme, it is preferred that described brush board side is provided with connection ring, described stay cord is connected with the described ring that is connected.
In technique scheme, it is preferred that described blade outer end is provided with arc-shaped convex.By arranging arc-shaped convex, prevent stay cord stuck on blade, also reduce the frictional force to stay cord simultaneously, extend stay cord service life.
The beneficial effects of the utility model are: this utility model can stop the condensed fluid produced on pipeline to be back on impeller or motor, and absorb this partial condensation liquid of erasing, it is to avoid blower fan damages because of condensed fluid backflow.
