Abstract
The utility model relates to a rectangle pipe blower which is an auxiliary air intake channel composed of an outer air intake flow guide plate, a flange, a casing, and an air intake flow guide plate. Thus, the utility model changes the vertical air intake and outtake mode of a centrifugal blower into the axial air intake and outtake mode, overcoming the large space occupation and inconvenient pipe connection of the centrifugal blower, and integrating the advantages of the centrifugal blower and the axial blower. The utility model has the characteristics of high wind pressure, little noise, small ground occupation, space saving, convenient installation, maintenance and management, etc. According to the requirement of practical situation, the utility model can also be formed by that an auxiliary air intake channel is arranged on the lower part (or the upper part) of an electrical motor. The utility model has the advantages of simple structure and low cost. When the utility model is connected with rectangle pipes, the utility model is simple and convenient in operation.
Description
The utility model belongs to a kind of improved ventilation unit.
Ventilation blower commonly used at present has centrifugal and axial-flow type.Centrifugal fan is compared with axial fan and is had the blast height, the advantage that noise is low.But since centrifugal fan spatially be in orthogonal two planes into and out of the air port, it is big to take up room, pipeline connects inconvenience, and needs special blower foundation, thereby has limited the range of application of centrifugal fan.The import and export of axial fan is on same axis, and it is little to take up room, and pipeline is easy to connect, is convenient to install.But its blast is little, the noise height, thus the purposes of axial fan is very restricted.
The purpose of this utility model is to overcome the shortcoming of existing centrifugal fan and axial fan, the advantage of comprehensive centrifugal fan and axial fan is widened the purposes of ventilation blower, makes it be convenient to use in ventilation and air conditioning engineering, save the space, be convenient to installation and maintenance and management.
Technical solution of the present utility model is that auxiliary air intake runner is made up of external air inlet mouth deflector, ring flange, casing, air inlet deflector, external air inlet mouth deflector is taper, the air inlet deflector is semicircle, air inlet is circular, volute is semicircle, and the air outlet deflector is the horn mouth shape, and impeller is circular, impeller respectively has an air inlet deflector at the motor upper and lower between motor and volute.According to actual needs, an air inlet deflector is arranged below motor, the air outlet deflector is half of horn mouth shape, and external air inlet mouth deflector is half a version of taper.
The utility model has the advantages that overcome that centrifugal fan takes up room greatly, pipeline connects inconvenience; Shortcomings such as the axial fan blast is little, noise height and combine the advantage of centrifugal fan, axial fan have the blast height, noise is little, floor space is little, joint sound space, are convenient to installation, maintenance and management.
Following accompanying drawing has been described an embodiment of the present utility model, below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the two auxiliary air intake runner structural principle schematic diagrames of the utility model;
Fig. 2 is the two auxiliary air intake runner A-A vertical views of the utility model;
Fig. 3 is auxiliary air intake runner structural principle schematic diagram of the utility model.
Fig. 4 is auxiliary air intake runner structural principle B-B vertical view of the utility model.
1-impeller, 2-motor, 3-volute, the auxiliary air intake runner of 4-, 5-ring flange, 6-air inlet, 7-maintenance dish, 8-casing, 9-bearing support, 10-external air inlet mouth deflector, 11-air inlet deflector, 12-air outlet deflector.
Fig. 1, Fig. 2 are two auxiliary air intake runners, are made up of external air inlet deflector, ring flange, casing, air inlet deflector.External air inlet mouth deflector is taper, and the air inlet deflector is semicircle, and air inlet is circular, and volute is semicircle, and the air outlet deflector is the horn mouth shape, and impeller is circular, and impeller respectively has an air inlet deflector at the motor upper and lower between motor and volute.After ring flange was connected to rectangular duct, wind entered two auxiliary air intake runners being made up of casing, air inlet deflector behind taper external air inlet mouth deflector, thereby centrifugal vertical turnover wind mode is become axial outlet and inlet mode.Also can be according to the actual conditions needs as Fig. 3, Fig. 4.Below the motor or above be an auxiliary air intake runner, air inlet deflector, an air outlet deflector are half of horn mouth shape, external air inlet mouth deflector is half the utility model of taper.
