Description

A kind of centrifugal pipeline fan
Technical field:
The utility model relates to a kind of Fan Equipment, particularly a kind of centrifugal pipeline fan.
Background technique:
General pipeline fan has axial-flow blower, centrifugal blower, flow-mixing blower fan etc.; The centrifugal pipeline blower fan is the mechanical energy that relies on input; Improve supply gas the side by side machinery of body of gas pressure, it is a kind of driven fluid machinery, mainly utilizes the impeller of high speed rotating that gas is quickened; Slow down, change airflow direction then, make kinetic energy convert potential energy to.Be divided into one-stage centrifugal pipeline fan and multistage centrifugal pipeline fan, generally all adopt the spirality casing structure, and adopt welding manner to accomplish each parts assembling more; Intake grill and exhaust outlet are positioned on two different direction planes; Structure is not compact, and difficulty is applied to the narrow and small occasion in space, simultaneously; Profile is irregular, is inconvenient to transport and install.In addition, existing centrifugal pipeline blower fan exists that volume is big, heavy, noise is big, manufacture cost is high and shortcoming such as maintenance inconvenience.
The model utility content:
The utility model is to the deficiency of existing technology, and a kind of centrifugal pipeline fan is provided, have simple in structure, profile is regular, noise is low, can be applicable to the advantage of the gas delivery of higher temperature.
In order to achieve the above object, the utility model adopts following technological scheme:
A kind of centrifugal pipeline fan is made up of rectangular enclosure, spirality casing and motor, and it is characterized in that: the two ends on the shell Vertical direction are respectively equipped with shell intake grill and air outlet of casing; Be provided with in the casing by motor-driven impeller; Casing is provided with the casing exhaust outlet, and the side of casing is provided with the casing intake grill, and the casing intake grill forms slip ring to impeller direction bending extension; The shell intake grill communicates with the casing intake grill, and the casing exhaust outlet communicates with air outlet of casing.
Described motor is installed on the motor plate, is fixed on together with motor plate on the outer wall of shell, also is provided with stiffening rib on the described shell, to increase the steadiness of whole blower fan.
The beneficial effect of the utility model is:
(1) enclosure designs becomes the rectangle rule shape, helps the transportation and the installation of blower fan, and being provided with of stiffening rib increased traveling comfort on the shell simultaneously, reduced the operational vibration noise, improved the working life of complete machine;
(2) electric machine external structural design, the heat that makes machine operation produce can in time dissipate, and guarantees that pipeline fan can adapt to higher gas flow temperature, and Applicable scope is wider, helps the installation and the maintenance of motor simultaneously.
Description of drawings:
Fig. 1 is the plan view of the structural representation of the utility model;
Fig. 2 is the side view of the structural representation of the utility model.
Among the figure: 1, shell, 2, casing, 3, motor, 4, impeller, 5, air outlet of casing, 6, the casing intake grill, 7, slip ring, 8, the shell intake grill, 9, motor plate, 10, stiffening rib, 11, the casing exhaust outlet.
Embodiment:
Embodiment: as depicted in figs. 1 and 2; A kind of centrifugal pipeline fan is made up of rectangular enclosure 1, spirality casing 2 and motor 3, it is characterized in that: the two ends on shell 1 Vertical direction are respectively equipped with shell intake grill 8 and air outlet of casing 5; Be provided with the impeller 4 that drives by motor 3 in the casing 2; Casing 2 is provided with casing exhaust outlet 11, and the side of casing 2 is provided with casing intake grill 6, and casing intake grill 6 forms slip ring 7 to impeller 4 direction bending extensions; Shell intake grill 8 communicates with casing intake grill 6, and casing exhaust outlet 11 communicates with air outlet of casing 5.
Described motor 3 is installed on the motor plate 9, is fixed on together with motor plate 9 on the outer wall of shell 1, also is provided with stiffening rib 10 on the described shell 1, to increase the steadiness of whole blower fan.
