Abstract
The invention relates to a speed-regulating centrifugal blower. A centrifugal blower is widely applied to sewage treatment, but has the defects of compression of a large amount of air for acting and heating, high temperature of an air drum and great reduction in the service life of a bearing due to poor heat dissipation of the bearing during high-speed rotation. Meanwhile, the blowing amount of the blower is fixed during use, so that corresponding air volumes cannot be adopted for sewage of different turbidity degrees. The speed-regulating centrifugal blower comprises a rack (5), and is characterized in that a driving motor (3) is arranged on the rack (5) through a base (4); the driving motor (3) is connected with a transmission (2); the transmission (2) is connected with an air drum (1); a bearing is arranged on a transmission shaft, which is connected with the air drum (1), of the transmission; and a temperature sensor is arranged on the bearing. The speed-regulating centrifugal blower is applied to speed-regulating fans applied to sewage treatment.
Description
Technical field:
The present invention relates to a kind of sewage-treatment plant, be specifically related to a kind of speed governing centrifugal blower.
Background technique:
Centrifugal blower is widely used in sewage treatment, but centrifugal blower in use compresses a large amount of air, the acting heating, and wind drum temperature height, bearing can not get good heat radiation and will cause the life-span of bearing to be reduced greatly in rotating at a high speed.Simultaneously blower in use blast volume fix, can not adopt corresponding air quantity to the sewage of different turbidities.
Summary of the invention:
The object of the present invention is to provide a kind of speed governing centrifugal blower.
The object of the present invention is achieved like this:
A kind of speed governing centrifugal blower, its composition comprises: stand, described stand is equipped with drive motor by base, described drive motor links to each other with speed changer, described speed changer links to each other with the wind drum, and described speed changer rouses on the transmission shaft that is connected with wind bearing is installed, and on the described bearing temperature transducer is installed.
Described speed governing centrifugal blower, described speed changer have three gears, and described speed changer is middle axis transmission.
Described speed governing centrifugal blower, described temperature transducer links to each other with power switch, and described power switch disconnects when receiving the overtemperature electric signal of temperature transducer.
Described speed governing centrifugal blower, described wind drum inside is equipped with impeller.
Beneficial effect:
1. the present invention realizes the control air output by speed changer, adapts to the sewage of different muddy concentration, makes the energy obtain reasonable use.
2. axis transmission improved transmission efficiency in the middle of the present invention adopted.
3. the present invention detects bearing temperature by the temperature transducer that is installed on the bearing, simultaneously the overtemperature signal is passed to switch, and it is too high that the protection bearing of cutting off the electricity supply is unlikely to temperature.
Description of drawings:
Accompanying drawing 1 is structural representation of the present invention.Among the figure, 1 is the wind drum, and 2 is speed changer, and 3 is drive motor, and 4 is base, and 5 is stand.
Embodiment:
Embodiment 1:
A kind of speed governing centrifugal blower, its composition comprises: stand 5, it is characterized in that: described stand 5 is equipped with drive motor 3 by base 4, described drive motor 3 links to each other with speed changer 2, described speed changer 2 links to each other with wind drum 1, on described speed changer 2 and the transmission shaft that wind drum 1 is connected bearing is installed, on the described bearing temperature transducer is installed.
Embodiment 2:
According to embodiment's 1 described speed governing centrifugal blower, described speed changer 2 has three gears, and described speed changer 2 is middle axis transmission.
Embodiment 3:
According to embodiment's 1 described speed governing centrifugal blower, described temperature transducer links to each other with power switch, and described power switch disconnects when receiving the overtemperature electric signal of temperature transducer.
