Variable-frequency vibration dust removal device based on energy converters

Abstract

The invention provides a variable-frequency vibration dust removal device based on energy converters. The variable-frequency vibration dust removal device comprises a multi-frequency ultrasonic generator, a funnel and two or more sets of the energy converters. The funnel is elastically connected to a fixing supporting seat, the funnel is provided with the two or more sets of energy converters, each set of energy converters comprise two energy converters, wherein the center frequency of the energy converters is the same, the energy converters are distributed on the surface of the funnel in a transversely symmetrical manner, the center frequency of different sets of energy converters is different, and the energy converters are distributed on the surface of the funnel from top to bottom at an equal interval. The input port of each energy converter is connected with the output port of the multi-frequency ultrasonic generator, and the energy converters work under the control of the multi-frequency ultrasonic generator. The variable-frequency vibration dust removal device has the advantages of being good in dust removal effect, high in automated degree, low in power consumption and the like.

Description

technical field [0001] The invention relates to the field of ultrasonic application technology, in particular to a transducer-based frequency conversion vibration dust removal device. Background technique [0002] During the production process of the cigarette factory, due to the certain humidity of the tobacco raw materials, dust often sticks to the surface of the funnel. When there is a lot of dust layer, it will have a certain impact on the passability of the funnel. At present, most of them use manual beating to remove the ash layer. This method has the disadvantages of low efficiency and high cost, and this method is good for removing dust without humidity, but it is difficult to achieve the purpose of dust removal for the ash layer with a certain humidity. [0003] Chinese patent CN201320427557.4 discloses a rapping mechanism for an electrostatic precipitator ash hopper, which uses a rapping motor and rapping nails to electrically remove dust, thereby improving the dus...

Problems solved by technology

However, this design requires someone to supervise the degree of dust removal, manually control the vibration time according to the actual situation, and maintain a frequency of rapping for a long time, which will cause damage to the funnel itself and consume a lot of energy.
