Abstract
The utility model relates to a fan wall which is particularly suitable to be used in air supply and exhaustion of large scale activity places needing a great air quantity such as a large scale industrial factory building, a gymnasium and an underground square, etc. The fan wall comprises a plurality of fans embedded in a wall body, wherein the fans are connected in parallel and are arranged under the support of a fan wall frame; the air inlet port and the air outlet port of the fan are respectively arranged at both sides of the wall body. The fan wall which is formed by the fans connected in parallel can provide a great air quantity through the simultaneous operation of the fans; when a fan arranged inside the fan wall breaks down, other fans still can operate; when one, two, three or N fans are started at the same time during use, which is equivalent to 1/N, 2/N, 3/N and a hundred percent air quantity adjustment; therefore, a user does not need to purchase a speed regulator or a frequency converter, which greatly reduces the cost in speed regulation or frequency conversion; moreover, the fan wall which has a more flexible structure can adjust the forms of the fan wall according to different places of different scales, thereby having a wider application scope.
Description
Technical field
The utility model relates to a kind of blower fan wall, adopts many typhoons machine parallel-connection structure form, is specially adapted to the use occasion of the big air quantity of demand, as large scale industry factory building and gymnasium, air-supply, the air draft in large-scale activity places such as underground square.
Background technology
The blower fan wall generally is installed on the basis of steel construction or xoncrete structure or on the wall, also adopts the lifting form, be used for to indoorly give, the exhaust body, finish the ventilation requirement of designing institute regulation.According to existing technology, under the situation that big air quantity demand is arranged, impeller will accomplish all that generally 1800mm-2000mm just can meet the demands when selecting conventional large fan for use, this also fan brought some problems: at first, accomplish the impeller diameter of 2000mm, the appearance and size of blower fan integral body is bigger, and the blower fan profile is done when big, certainly will require material therefor must be abundant, enough intensity is arranged, overall weight strengthens, and has also improved cost simultaneously; Secondly, accomplish that the large fan of 2000mm impeller diameter can only adopt belt transmissioning mode, it is low to drive efficient than direct connection.Therefore, when requirement being arranged aspect more than market is to blower fan, still there is certain obstacle in this class large fan aspect being suitable for.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of blower fan wall of new structure, utilizes the small-sized fan large fan that replaces in parallel, and the conventional large-scale good blower fan of solution send at big air quantity, air draft situation lower volume is huge, the problem of Heavy Weight.
The utility model addresses the above problem the technical scheme of being taked: a kind of blower fan wall, comprise the most typhoon machines that are embedded in the body of wall, wherein, the connection parallel with one another of described most typhoon machines, arranged by blower fan wall frame supported, the air inlet of blower fan and air outlet are separately positioned on the both sides of body of wall.The main purpose of blower fan wall is to provide indoor and send, air draft, and indoor sultry air is taken out rapidly toward outdoor, keeps room air unimpeded.
On the basis of such scheme, most typhoon machines of described blower fan wall are arranged side by side.
On the basis of such scheme, most typhoon machine stacked arrangement of described blower fan wall.Can carry out simultaneously with stacked side by side, thereby constitute the blower fan wall.
The blower fan of described blower fan wall is by exhaust casing, centrifugal impeller, motor and be configured to, and the exhaust casing two ends constitute air inlet and air outlet.Adopt centrifugal impeller stronger with respect to its effect of common impeller.
The centrifugal impeller of described blower fan is connected driving with the motor that is equipped with separately.Motor is positioned at impeller exhaust casing central interior, and motor shaft directly links to each other with centrifugal impeller.And realizing separate unit control thus, the function of Qi Donging has simultaneously thoroughly solved the unfavorable situation that must whole system stops because of a typhoon machine fault.
In order to strengthen security, be equipped with protection network between the centrifugal impeller of the air inlet of described blower fan exhaust casing, air outlet and inboard and the motor.
For guaranteeing the firm of blower fan wall, described blower fan is fixedlyed connected with body of wall by securing member, and is provided with encapsulant between blower fan exhaust casing and the body of wall.
The beneficial effects of the utility model are:
1, adopt many typhoons machine blower fan wall that constitutes in parallel, work when can pass through parallel fan provides big air quantity, has avoided large fan because the cost problem that problem of materials causes;
2, when certain typhoon machine breaks down in the blower fan wall, other blower fans still can continue operation, when avoiding the big model fan trouble of separate unit, send, the stagnation of exhaust system;
3, start shooting simultaneously when using when blower fan carries out 1,2,3, N platform, be equivalent to the adjusting of 1/N, 2/N, 3/N, 100% air quantity, need not purchase speed governing or frequency converter separately once more, also reduce the cost of speed governing or frequency conversion greatly;
4, be roughly square large fan with respect to shape, under the situation that air quantity equates, adopt most platform small-sized fans to arrange and form the blower fan wall, its structure is more flexible, can adjust the form of blower fan wall according to the different occasion of different scales, and applicable surface is wideer.
