Abstract
The utility model relates to a portable centrifugal fan. The portable centrifugal fan comprises a housing, a supporting leg, a main shaft, belt pulleys and bearing blocks; threaded holes for the multi-angle adjustment of the housing and the supporting leg are formed in the housing; the housing and the supporting leg are connected by bolts; the main shaft of the centrifugal fan is transversely arranged; two ends of the main shaft are placed outside the housing and are connected with the belt pulleys through key grooves; and the bearing blocks in which bearings are embedded are positioned in the housing. Compared with the prior art, the portable centrifugal fan has the advantages of being applicable to a place with large flow and high pressure, capable of solving the problem of complicated installation, energy-saving, environment-friendly, cheap but excellent and high in utilization rate, and providing the convenience for a customer; the portable centrifugal fan is suitable for being applied to the field requiring frequent ventilating; and the fan is small in size, large in flow, high in pressure, high in efficiency, low in noise, light and convenient, and easy to disassemble and assemble.
Description
Technical field
The utility model relates to a kind of blower fan, particularly a kind of portable centrifugal blower.
Background technique
Portable centrifugal blower is applicable to the aeration-drying of grain; Can be used for place emergency ventilation ventilation or the reinforcement heat radiations such as metallurgy, chemical industry, light industry, medicine and civil building, purge.Because traditional portable fan is all selected axial-flow blower, although the axial-flow blower flow is large, but wind stress factor is little, improves pressure in pipeline as needs, must connect by several axial-flow blowers.And axial-flow blower can not change the flow direction of medium in airduct, can only guide by pipeline the flow direction of medium.
The model utility content
The model utility purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of volume little, and flow is large, and pressure is high, and efficient is high, and noise is little, and light easy-to-dismount portable centrifugal blower.
The technical solution adopted in the utility model: for achieving the above object, the utility model adopts following technological scheme:
A kind of portable centrifugal blower, comprise casing, supporting leg, main shaft, belt pulley and bearing support, but described casing is provided with the tapped hole that allows casing and supporting leg multi-angle adjust, described casing and supporting leg are connected by screw, the main shaft cross setting of described centrifugal blower, the two ends of main shaft are positioned at outside casing, and the two ends of main shaft are connected with belt pulley by keyway, and the bearing support of embedded bearing is installed in described casing.
As optimization, described belt pulley is comprised of the first belt pulley and the second belt pulley, and described the second belt pulley is set on the first belt pulley, fixes by interior hexagonal cone end Cock screw.
As optimization, described bearing support is connected and fixed by three sections bearing ribs and forms.
The installation of casing and supporting leg can be by the multi-angle adjustment.Leave the tapped hole of installing with the supporting leg multi-angle during casing design, generally leave the installation preformed hole of three kinds of angles, if any specific (special) requirements, can produce according to the actual requirement design, in actual use, the user can according to the pipe angle at scene, adjust arbitrarily the exhaust outlet angle of blower fan.And dismounting is also very easy, only need pull down three screws on supporting leg both sides, adjusts the casing angle and the screw of supporting leg is fixed is got final product.And original hole that removes blocks with screw and gets final product, and can not cause like this leaking out of casing, affects the performance of blower fan.
The spindle design of blower fan becomes an optical axis, processing is simple like this, cost is also cheap, the both sides spindle nose of main shaft all is reserved with the keyway that matches with belt pulley, the adjustment in orientation when facilitating on-the-spot as installed belt pulley like this: traditional belt pulley is whole parts, the blower fan of this type is for the ease of in actual use quickly-detachable, the belt pulley that aims at blower fan has been done particular design, its belt pulley is designed to detachable two, adopt thread section excessively to connect in the middle of two belt pulleys, at last again with clenching locked with interior hexagonal cone end Cock screw.After this design, belt pulley can be adjusted the mounting point according to on-the-spot motor true bearing, in use, only need unclamp interior hexagonal cone end Cock screw, two belt pulleys is taken apart again be fixed to the other end and get final product.
The bearing support of blower fan is formed by connecting by three sections bearing ribs, three sections bearing ribs have directly surrounded the bearing support of an embedded bearing, this design not only can reduce the cost of buying bearing support, and has alleviated the weight of fuselage, exclusive one time punching molded gusset, not only be designed with the groove of laying bearing, and the whole body has been covered with stiffening rib, has strengthened torsional buckling power, and intensity is high, and succinctly attractive in appearance, with stereoscopic impression.In use, installing/dismounting is quite easy, only needs the several bolts of dismounting, nut just can easily settle.
Beneficial effect: compared with prior art, the utility model can be applied in the product institute of large flow, high pressure, and has solved the installation complicated situation, energy-conserving and environment-protective, good and cheap, utilization ratio is high, for the client provides convenience, the utility model often need to be applicable to the field of ventilation, and this blower fan volume is little, and flow is large, pressure is high, efficient is high, and noise is little, and light easy to assemble.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
as Fig. 1, a kind of portable centrifugal blower shown in 2, comprise casing 1, supporting leg 2, main shaft 3, belt pulley 4 and bearing support 5, but casing 1 is provided with the tapped hole 6 that allows casing 1 and supporting leg 2 multi-angles adjust, casing 1 and supporting leg 2 are connected by screw, main shaft 3 cross settings of centrifugal blower, the two ends of main shaft 3 are positioned at outside casing 1, the two ends of main shaft 3 are connected with belt pulley 4 by keyway, the bearing support 5 of embedded bearing is installed in casing 1, belt pulley 4 is comprised of the first belt pulley and the second belt pulley, the second belt pulley is set on the first belt pulley, fix by interior hexagonal cone end Cock screw, bearing support 5 is connected and fixed by three sections bearing ribs and forms.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
