Abstract
The utility model relates to a high-pressure fan, comprising a fan shell and a plurality of blades installed in the shell. The blades are driven to rotate through a power machine and are connected to the same rotating shaft in series, and the rotating shaft is driven by the power machine. The fan shell is in a barrel shape, the bottom of the fan shell is provided with a high-pressure airflow outlet, and the fan shell is internally provided with a cooling device. The utility model has reasonable design, the multi-level blades are adopted to rotate at high speed so that wind power with very high strength can be output, and due to the arrangement of the cooling device, the fan can work for a long time.
Description
Technical field
The utility model relates to a kind of high pressure positive blower that is used to produce high pressure draught.
Background technique
Existing blower fan generally only is provided with one deck blade, and the wind-force that is produced is little, thereby its application area is very narrow, is not suitable for extensive use.
The model utility content
The technical problems to be solved in the utility model provides a kind of high pressure positive blower that can produce powerful wind-force.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of high pressure positive blower comprises the branch engine housing and is installed on the interior blade of housing that blade pass is crossed the power engine rotary driving, described blade is a multi-disc, is connected in series with in the same rotating shaft, and rotating shaft drives by power engine, described housing is the staving shape, and the bottom is provided with the high pressure draught outlet.
As the improvement to such scheme, rotating shaft is positioned at the housing axle center, and rotating shaft and housing all are fixed on the exterior object by supporting base.
And each blade reduces towards housing bottom direction lifting surface area successively along rotating shaft.
As further improvement of these options, cooling unit is installed in Blower Housing.This cooling unit comprises that being fixed in inner walls extends cooling bulge loop between the blade, cooling bulge loop inner hollow, in be full of cooling liquid, have and the opening that cools off the bulge loop internal communication at the housing outer wall.
The utility model is reasonable in design, adopts the great wind-force of multistage blade high speed rotating output intensity, and is provided with cooling unit, has guaranteed that blower fan can work long hours.
Description of drawings
Accompanying drawing 1 is the utility model embodiment overall structure schematic representation;
Accompanying drawing 2 is an A portion structure for amplifying schematic representation in the accompanying drawing 1.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is described in further detail below in conjunction with specific embodiment and accompanying drawing:
Shown in accompanying drawing 1,2, the high pressure positive blower that present embodiment disclosed comprises branch engine housing 1 and is installed on blade 2 in the housing 1, blade 2 is by the power engine rotary driving, described blade 2 is a multi-disc, be connected in series with in the same rotating shaft 3, rotating shaft 3 drives by power engine, and this housing 1 is the staving shape, and the bottom is provided with high pressure draught outlet 11.
Because blade 2 is easy to generate high temperature in the process of high speed rotating, too high in order to prevent temperature, the normal running of image documentation equipment then is provided with cooling unit in Blower Housing 1.In the present embodiment, this cooling unit comprises that being fixed in housing 1 inwall extends cooling bulge loop 12 between the blade 2, cooling bulge loop 12 inner hollow, in be full of cooling liquid, have and the opening that cools off bulge loop 12 internal communication at housing 1 outer wall, opening is communicated with the external refrigeration circulation loop, and heat is dissipated.When blade 2 ran up, the cooling liquid of cooling in the bulge loop 12 began tape loop and walks heat and cool off.
More than be the preferred version of embodiment for the utility model realization; and indefiniteness is exhaustive; the utility model can also have other variations under same idea; need to prove; under the prerequisite that does not break away from the present utility model design, any conspicuous replacement is all within the utility model protection domain.
