Abstract
The present invention relates to an improved draught fan shell which comprises a shell body. The shell body comprises a volute and an air outlet formed in a side wall of the volute; a chamber communicated with the air outlet is formed in the volute; an impeller is arranged in the chamber; a first filtering layer is arranged between the chamber and the impeller; an air inlet is formed in the volute; a second filtering layer is arranged at the joint of the air inlet and the volute; and a third filtering layer is arranged at the air outlet. The improved draught fan shell has the advantages that impurities can be filtered out through the first filtering layer, the second filtering layer and the third filtering layer, the cleanness in the shell body is ensured, the cleanness at the air outlet is also ensured, and the service life of the draught fan is prolonged.
Description
Technical field
The present invention relates to the fan casing of a kind of improvement.
Background technology
Blower fan is a kind of mechanical energy relying on input, improves gas pressure and supplies gas side by side the machinery of body, is that usually said blower fan includes ventilation blower, aerator and electromotor to gas compression and the abbreviation of one conveying machinery.The main structural components of blower fan includes casing, impeller, driving member etc., and the casing of blower fan is during work, and too much dust can be put aside in inside, causes the hydraulic performance decline of blower fan.It would therefore be desirable to seek a kind of new technology to solve this problem.
Summary of the invention
It is an object of the invention to: for above-mentioned deficiency, it is provided that the fan casing of a kind of improvement.
For achieving the above object, the technical solution used in the present invention is:
A kind of fan casing of improvement, including casing ontology, casing ontology includes spiral case and is arranged on the air outlet of spiral case sidewall, the chamber connected with air outlet it is provided with in spiral case, being provided with impeller in chamber, be provided with the first filter course between chamber and impeller, spiral case is provided with air inlet, air inlet is provided with the second filter course with the junction of spiral case, is provided with the 3rd filter course at air outlet.
Leg it is provided with bottom spiral case.
The upper end of spiral case is monosymmetric is provided with hanger.
Sewage draining exit it is provided with bottom spiral case.
Due to the application of technique scheme, the present invention compared with prior art has the advantage that
Contaminant filter can be fallen by the first filter course, the second filter course and the 3rd filter course, it is ensured that the cleaning in casing ontology, also ensure that the cleaning at air outlet, extends the service life of blower fan.
Accompanying drawing explanation
Accompanying drawing 1 is the embodiment of the present invention one external structure schematic diagram.
In the figures above: 1-casing ontology, 2-spiral case, 3-air outlet, 4-chamber, 5-impeller, 6-the first filter course, 7-air inlet, 8-the second filter course, 9-the 3rd filter course, 10-leg, 11-hanger, 12-sewage draining exit.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the invention will be further described:
Embodiment one: the fan casing of a kind of improvement
As shown in Figure 1, the fan casing of a kind of improvement of the present invention, including casing ontology 1, casing ontology 1 includes spiral case 2 and is arranged on the air outlet 3 of spiral case 2 sidewall, is provided with the chamber 4 connected with air outlet 3, is provided with impeller 5 in chamber 4 in spiral case 2, the first filter course 6 it is provided with between chamber 4 and impeller 5, spiral case 2 is provided with air inlet 7, and air inlet 7 is provided with the second filter course 8 with the junction of spiral case 2, is provided with the 3rd filter course 9 at air outlet 3.
Leg 10 it is provided with bottom spiral case 2.
The upper end of spiral case 2 is monosymmetric is provided with hanger 11.
Sewage draining exit 12 it is provided with bottom spiral case 2.
Due to the application of technique scheme, the present invention compared with prior art has the advantage that
Contaminant filter can be fallen by the first filter course, the second filter course and the 3rd filter course, it is ensured that the cleaning in casing ontology, also ensure that the cleaning at air outlet, extends the service life of blower fan.
The above is the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, on the premise of without departing from principle of the present invention; can also make some improvement or replacement, these improve or replace and also should be regarded as protection scope of the present invention.
