The utility model aims to overcome the defects of the prior art and provide an air inlet box based on an air blower, wherein the upper end of the air inlet box main body is sealed and fixed by a cover plate, the lower end of the air inlet box main body is provided with a supporting seat and fixed with a base, a gas storage bin is arranged in the air inlet box main body, and an air inlet channel of an air inlet port is communicated with the gas storage bin; the flange of giving vent to anger with the gas storage bin intercommunication is established to the air inlet box main part, establishes a plurality of filtration pore division boards in the gas storage bin and moves about freely and quickly each other and set up and reciprocal anchorage, and the both ends of filtration pore division board all are fixed with the interior wall connection of air inlet box main part, and the gas pocket that the filtration pore division board equipartition runs through, air inlet box main part lower extreme establish discharge valve and with the gas storage bin intercommunication, the utility model discloses can provide the dose of very big surplus for the required air of large-scale air-blower during operation, avoid the air-blower to lead to large-scale air-blower.
In order to achieve the above purpose, the technical scheme of the utility model is that: a fan capable of forming an inclined air duct comprises an air inlet box main body, wherein the upper end of the air inlet box main body is sealed and fixed by a cover plate; the lower end of the air inlet box main body is provided with a supporting seat, and the lower end of the supporting seat is provided with a base;
the air inlet box main body is internally provided with an air storage bin, one end of the air inlet box main body is provided with an air inlet port, and an air inlet channel in the air inlet port is communicated with the air storage bin;
the air inlet box main body is provided with an air outlet flange, and an inner air channel of the air outlet flange is communicated with the air storage bin;
a plurality of filter hole isolation plates are arranged in the gas storage bin in a longitudinal and transverse mode and are fixed with each other, and two ends of each filter hole isolation plate are connected and fixed with the inner wall of the air inlet box main body;
an exhaust valve is arranged at the lower end of the air inlet box main body and communicated with the air storage bin.
Further, air holes are uniformly distributed through the filter hole isolation plates.
The utility model has the advantages that: the utility model discloses can provide the dose of very big surplus for the required air of large-scale air-blower during operation, avoid the air-blower because of the not enough work efficiency that leads to large-scale air-blower of inspiratory air capacity.
Drawings
FIG. 1 is a schematic view of the present invention;
fig. 2 is a sectional view taken along the line a of fig. 1.
In the figure: the gas storage tank comprises a gas inlet tank main body 1, a supporting seat 2, a base 3, a gas outlet flange 4, a cover plate 5, a filter hole isolation plate 6, a gas outlet valve 7, a gas inlet port 8, a gas inlet channel 9 and a gas storage bin 10.
Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
As shown in figure 1, an air inlet box based on a blower is characterized in that the upper end of an air inlet box main body 1 is sealed and fixed by a cover plate 5, the lower end of the air inlet box main body 1 is provided with a support seat 2 and fixed with a base 3 at the lower end, an air storage bin 10 is arranged in the air inlet box main body 1, an air inlet channel 9 in an air inlet port 8 at one end of the air inlet box main body 1 is communicated with the air storage bin 10, the diameter of an inlet port of the air inlet channel 9 is larger than two thirds of the height of the air storage bin 10, the diameter of the inlet port of the air inlet channel 9 is far larger than the diameter of an inner air channel of an air outlet flange 4, the air inlet channel 9 starts to be bent outwards in a trumpet shape from the middle position and extends and is communicated with the whole side surface of the air storage bin 10, when the blower does not work, the, the air inlet of air-blower can be followed the air intake of storing in the gas storage bin 10 of big space, has solved the problem that the air-blower initial stage is admitted air and is inhaled the capacity not enough to after the air in the gas storage bin 10 is sucked, outside air gets into the replenishment from inlet channel 9 fast, and outside air flows at inlet channel 9 fast and forms the siphon effect, has further accelerated the entering of outside air, has accelerated the air that has replenished in the gas storage bin in step.
Establish a plurality of filtration pore division boards 6 in the gas storage bin 10, filtration pore division board 6 is for moving about freely and quickly setting and reciprocal anchorage, the both ends of filtration pore division board 6 all are fixed with the interior wall connection of air inlet box main part 1, the gas pocket that 6 equipartitions of filtration pore division board run through, the filtration pore division board 6 setting of moving about freely and quickly structure, do benefit to and can produce collision and diffusion effect after meeting filtration pore division board 6 from the air that inlet channel 9 high-speed got into, be convenient for fill all spaces in the gas storage bin rapidly, direct striking is at the gas storage bin inner wall and form the problem of turbulent flow after having solved no filtration pore division board 6 air straight line gets into.
An exhaust valve 7 is arranged at the lower end of the air inlet box main body 1, and the exhaust valve 7 is communicated with the air storage bin 10 and is used for exhausting air during overhaul.
The air inlet box main body 1 is allowed to be provided with a closed access door on the side surface, so that maintenance personnel can conveniently enter the air inlet box main body 1 for maintenance, although theoretically, the air inlet channel 9 can also enter the air inlet box main body, in practical application, the air outlet flange 4 is fixedly connected with an air inlet port of an air blower, the air inlet port 8 is high in height, and the maintenance personnel jump to the bottom of the air storage bin 10 after entering from the high air inlet port and have potential safety hazards.
The utility model discloses can provide the dose of very big surplus for the required air of large-scale air-blower during operation, avoid the air-blower because of the not enough work efficiency that leads to large-scale air-blower of inspiratory air capacity.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention.
