Abstract

A dust-exhaust centrifugal blower includes a base, a bracket, an impeller, a volute, a belt, and a motor fixed at the base and connected to the impeller via the belt. The volute is provided thereon with an air inlet and an air outlet, and fixed at the base. One side of the volute is fixed at the base via a bracket in strengthening manner. The impeller is a multi-vane type impeller, and arranged in the volute and between the air inlet and the air outlet. A grid dust exhaustor is mounted in the volute, and between the impeller and the air outlet, to realize dust exhaust action. The invention has the advantages of strong applicability, high efficiency, large flow rate, small noise, compact structure, light weight, and small floor occupation. It can not only be used as a general blower, but also has dust collection function, to transport dust-containing air.

Description

The dust discharge centrifugal blower
Technical field:
The utility model belongs to the blower fan technical field, is specifically related to a kind of dust discharge centrifugal blower.
Background technique:
Because all wanting of wind pressure ratio axial-flow blower, diagonal flow fan and the flow-mixing blower fan of centrifugal blower is high, therefore, is widely used in the commercial production, is used for carrying clean air.But its shortcoming is to carry the air that contains dust, that is to say that centrifugal blower does not have dedusting function; If carry the air contain dust with centrifugal blower; Must add dusting apparatus, and so just increase cost, make floor space strengthen simultaneously; Efficiency consumption is big, and dust removal efficiency is low.Therefore, be necessary to design a kind of dust discharge centrifugal blower, can carry the air that contains dust, also can carry clean air, at one stroke dual-purpose.
The model utility content:
In order to achieve the above object, the utility model adopts following technological scheme:
The dust discharge centrifugal blower comprises base, support, impeller, spiral case, belt and motor, and motor is fixed on the base, connects impeller through belt.Described spiral case is provided with intake grill and exhaust outlet, and spiral case is fixed on the base, and a side of spiral case is strengthened being fixed on the base through support; Described impeller is the multiple-airfoil type impeller, between the intake grill and exhaust outlet in spiral case; The grid dust exhaustor is installed in the spiral case, between impeller and exhaust outlet, plays the dust discharge effect.
The utility model product applicability is strong, efficient is high, flow is big, noise is little, compact structure, in light weight, floor space is little, not only can be used as common blower fan usefulness, but also has dedusting function, can carry dust laden air.
Description of drawings:
Fig. 1 is the plan view of the utility model structural representation;
Fig. 2 is the left view of the utility model structural representation.
Among the figure: 1, base, 2, support, 3, intake grill, 4, impeller, 5, exhaust outlet, 6, spiral case, 7, belt, 8, motor, 9, the grid deduster.
Embodiment:
As depicted in figs. 1 and 2, the dust discharge centrifugal blower comprises base 1, support 2, impeller 4, spiral case 6, belt 7 and motor 8, and motor 8 is fixed on the base 1, connects impeller 4 through belt 7.Described spiral case 6 is provided with intake grill 3 and exhaust outlet 5, and spiral case 6 is fixed on the base 1, and a side of spiral case 6 is strengthened being fixed on the base 1 through support 2; Described impeller 4 is the multiple-airfoil type impeller, between the intake grill 3 and exhaust outlet 5 in spiral case 6; Grid deduster 9 is installed in the spiral case 6, between impeller 4 and exhaust outlet 5, plays the effect of dedusting noise reduction.
Working principle: during work, motor 8 rotates through belt 7 impeller 4, produces negative-pressure sucking, and air is sucked in the spiral case 6 from intake grill 3, and after 4 superchargings of multiple-airfoil type impeller, through the dedusting effect of grid deduster 9, cleaned air is blown from exhaust outlet 5.
