Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically connected, electrically connected or can communicate with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1, the present invention provides an embodiment: a static pressure box for circular fiber fabrics comprises a static pressure box 2, wherein an air inlet 1 and an air outlet 4 are arranged on the circumferential surface of the static pressure box 2; the two ends of the static pressure box 2 are sealed through plugs 3; the static pressure box 2 is internally provided with a plurality of keels 5, and the keels 5 are distributed on the axial direction of the static pressure box 2 at equal intervals.

When air enters the static pressure box 2 through the air inlet 1, because the volume of the static pressure box 2 is larger, the air speed of the air flow is reduced and then the air flow is mixed together in the static pressure box 2, so that the mutual impact of the air flow is reduced, the dynamic pressure of the air flow is reduced, the static pressure is increased, and the effects of stabilizing the air flow, reducing the vibration of the air flow and reducing the noise are achieved; meanwhile, because both ends are blocked by the plugs 3, airflow is accumulated in the static pressure box 2 after entering the static pressure box 2 and can only be discharged through the air outlet 4, and the effect of supplying air at a longer distance is achieved.

Because the static pressure box 2 is woven by fiber fabrics, the total weight is light, the installation is convenient, and the use requirements can be more easily met in places with limited bearing and larger construction difficulty; because through fossil fragments 5 make static pressure case 2 becomes cylindricly, compares in cuboid static pressure box, and the inside windage of circular structure is littleer, and inside static pressure is closer, and the effect that the dynamic pressure converts the static pressure is better.

The number of the air outlets 4 is one, and the air outlets are arranged in the middle of the static pressure box 2; the number of the air inlets 1 is at least three, and the air inlets and the air outlets 4 are symmetrically arranged on the static pressure box 2; therefore, when air enters the static pressure box 2 from the air inlet 1, the space of the static pressure box 2 is large, the speed of the air flow is reduced, all the air flows are mixed in the static pressure box 2 and then are sent out from the air outlet 4, the stable flow is realized, meanwhile, the pressure of the air flow flowing out is increased, and further, the long-distance conveying of the air is realized.

Because the air outlet 4 and the air inlet 1 are made of the same material as the static pressure box 2, one end of the air outlet 4 and one end of the air inlet 1 are sewn with the static pressure box 2, and the other end of the air outlet 4 and the other end of the air inlet 1 are protruded outwards along the radial direction of the static pressure box 2, the static pressure box 2 is convenient to connect with a fan, and the whole weight of the equipment is further reduced.

Because the cross section of fossil fragments 5 is circular, all make static pressure case 2 keep cylindricly when ventilating with the obstructed wind, reduce the impact when the air current just gets into, keep the aesthetic property.

In order to further facilitate the connection between the static pressure box 2 and the fan and the connection between the static pressure box 2 and the gas pipe, the plug 3, the air inlet 1 and the air outlet 4 are all arranged in a cylindrical shape, and the plug 3 is sewn at two ends of the static pressure box 2, so that the fixed connection between the plug 3 and the static pressure box 2 is facilitated.

Through the technical scheme, the device integrates the degree height, with static pressure case 2, a plurality of air intake 1, air outlet 4 sets in an organic whole, consequently, it is great that some spaces need the air supply volume, single unit fan can't satisfy, when need using the parallelly connected use of many fans, can connect static pressure case 2 with many fans, under keel 5 support in static pressure case 2's inside, static pressure case 2 keeps circularly, reduction air current that can step forward strikes each other, reduce the air current dynamic pressure, increase the static pressure, play stable air current, reduce the air current vibrations, reduce the noise, reach the effect of farther distance air supply.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
