Technical Field
The utility model belongs to the technical field of fluid machinery, a fan, in particular to one-way air supply non return formula swirl fan is related to.
Background
The vortex fan is a high pressure fan, the output pressure is much higher compared with the common centrifugal fan, the working principle is that the air in the middle of the blade of the impeller is acted by the centrifugal force and moves towards the edge of the impeller, the air enters the annular cavity of the pump body and then returns to the impeller and circulates again from the starting point of the blade in the same way, because the air is uniformly accelerated, the air is blown out in the form of spiral line by the circulating airflow generated when the impeller rotates, the air leaves the pump body with extremely high energy, because of various characteristics of the vortex fan, the vortex fan is widely applied in industrial application, the current vortex fan is also applied to oxygenation of ponds, but the problem exists in the application of the vortex fan with the conventional structure, because the oxygenation of the ponds are directly connected to the water bottom through the water pipe connection for exhausting in an inverted mode, when the phenomenon of the impeller of the fan occurs, the water in the pond can be sucked into the interior of the fan to cause the damage of the motor.
Disclosure of Invention
The utility model aims at the above-mentioned problem that exists among the prior art, provide one kind can prevent effectively that the one-way air supply non return vortex fan that rivers suck-back phenomenon takes place.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides an one-way air supply non-return formula swirl fan, includes base, motor and pump head, the pump head link firmly on the base, the inside of pump head is provided with impeller and motor and links firmly in the pump head center and with the inside impeller connection of pump head, its characterized in that, the below of pump head is provided with an air inlet section of thick bamboo and an air outlet section of thick bamboo, and an air inlet section of thick bamboo and an air outlet section of thick bamboo wear to establish the bolt through respectively in its both sides and link firmly on the pump head, the inside of an air outlet section of thick bamboo is provided with the mounting panel, and the both sides cover of mounting panel is located and is fixed through the nut on the bolt, and the outer wall of mounting panel is the same with the inner wall structure of an air outlet section of thick bamboo and the sealed cooperation of contact, and the vent has been seted up at the.
This one-way air supply check formula swirl fan's technical effect does: the design of vent and baffle is equivalent to a check valve, and the air current can only flow from the play dryer, and the vent will be closed when the impeller reverses and prevent the suck-back phenomenon and make rivers inhaled to the mounting panel directly links firmly on the bolt through the nut, does not change original mounting structure, and it is more convenient to assemble.
In the above one-way air supply non-return type vortex fan, the structure of the air inlet cylinder is the same as that of the air outlet cylinder, and the mounting plate is reversely mounted.
In foretell one-way air supply non-return vortex fan, the backup pad has vertically been linked firmly through the screw between motor bottom and the base, and the both sides face and the backup pad of air inlet section of thick bamboo and play dryer lean on.
Compared with the prior art, this one-way air supply non return formula swirl fan sets up reverse non return structure each other through passing in and out the dryer, and does not change original mounting structure, has the advantage that effectively prevents rivers suck-back.
