Description

High-efficient low noise filtration module unit

Technical Field

The utility model belongs to the technical field of air purification equipment technique and specifically relates to a high-efficient low noise filtration module unit.

Background

The existing air filtering unit generally adopts a design without an air duct or an air duct added in a box body, the improvement on the system efficiency is limited, the improvement on the system efficiency is mainly improved through the fan efficiency, and the improvement on the system efficiency is also limited.

SUMMERY OF THE UTILITY MODEL

In order to overcome the not enough of current filtration unit inefficiency, the utility model provides a high-efficient low noise filtration module unit fixes the wind-guiding curb plate and forms the wind channel on heterotypic bottom plate, then combines to form a cavity and four at least air outlets with the box.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a high-efficient low noise filtration module unit, includes heterotypic bottom plate, be fixed with four at least the same wind-guiding curb plates on the heterotypic bottom plate respectively, it is protruding through punching press or roll-in shaping punching press in heterotypic bottom plate face middle part, wind-guiding curb plate one end is through the shaping of buckling for circular arc section and the plane section transition position of not punching forming.

Furthermore, the bulges on the special-shaped bottom plate are formed by punching and the cross sections of the bulges are trapezoidal or arc-shaped.

Furthermore, the side edge comprising the bulge and the surface of the special-shaped bottom plate form an included angle, and the included angle degree is 0-90 degrees.

Furthermore, the radian range of the arc section on the air guide side plate is 0-90 degrees.

The beneficial effects of the utility model are that, the utility model discloses a high-efficient low noise filtration module unit, fix four at least wind channels of formation on heterotypic bottom plate with at least four wind-guiding curb plates, then combine to form a cavity and four at least air outlets with the box, this structure has optimized the air outlet duct, make the air can follow the runner after flowing from the fan and flow, very big reduction the flow loss, the system efficiency who has promoted effectively, and simultaneously, because the air flows the back along the runner motion from the impeller, very big reduction the speed variation gradient, thereby the effectual pressure pulsation that has restrained, make the noise obtain reducing.

In the figure, 1, a special-shaped bottom plate, 2, an air guide side plate, 3, a bulge, 21, an arc section and 22, a plane section are arranged.

Detailed Description

As fig. 1 is the utility model discloses a structural schematic diagram, a high-efficient low noise air filtration module unit, including heterotypic bottom plate 1, be fixed with four at least the same wind-guiding curb plates 2 on the heterotypic bottom plate 1 respectively, 1 face middle part of heterotypic bottom plate is protruding 3 through stamping forming punching press play, 2 one end of wind-guiding curb plate are circular arc section 21 and the plane section 22 transition position of not stamping forming through the punching press or roll-in shaping through the shaping of buckling. The center of the surface of the special-shaped bottom plate 1 is provided with a mounting hole for mounting a fan, and the surface of the special-shaped bottom plate 1 is provided with a threaded hole for fixing the air guide side plate 2.

Referring to fig. 2 and 3, the protrusion 3 of the special-shaped bottom plate 1 is formed by punching, and the cross section of the protrusion 3 is trapezoidal or circular arc. The side edge of the bulge 3 forms an included angle with the surface of the special-shaped bottom plate 1, and the degree of the included angle is 0-90 degrees. The bulges 3 on the special-shaped bottom plate 1 are used as a buffer area after the impeller airflow flows out, so that the flow loss of the air after the air flows out of the impeller is reduced, and the efficiency is improved.

As shown in fig. 4 and 5, the arc section 21 of the air guide side plate 2 has an arc range of 0 ° to 90 °. The radian of circular arc section 21 is adjusted the decision according to the fan of in-service use, wind-guiding curb plate 2 is fixed on heterotypic bottom plate 1, then form the wind channel between two adjacent wind-guiding curb plates 2, this wind channel provides a guide for the gas that flows out the impeller, make the air current flow out can flow along the wind channel behind the impeller, and then reduce the flow and scatter the loss, improve overall efficiency, simultaneously, because the air can flow along the flow channel after flowing out from the impeller, very big reduction speed variation gradient, thereby the effectual noise that has suppressed, make the noise reduce.

During the use, fix four at least wind channels of formation on heterotypic bottom plate 1 with even circumference array in proper order to at least four wind-guiding curb plate 2 opposite sides, then combine to form a cavity and four at least air outlets with the box with 2 opposite sides of wind-guiding curb plate, this structure has optimized the exhaust passage, make the air flow along the runner after flowing from the fan, arch 3 on the heterotypic bottom plate 1 cushions the air current that the impeller flows, very big reduction the flow loss, the system efficiency who has promoted effectively, and simultaneously, because the air flows the air duct motion of back along heterotypic bottom plate 1 and wind-guiding curb plate 2 formation from the impeller, very big reduction the speed variation gradient, thereby effectual pressure pulsation that has restrained, make the noise obtain reducing.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
