Embodiment 1

[0034] Such as Figure 1 to Figure 4 As shown, the present invention discloses an ash hopper provided with a vibrating ash loosening device, comprising an ash hopper main body 1 and a plurality of ash loosening devices 2, the ash hopper main body 1 is a conical structure, and the ash loosening devices 2 are set On the ash hopper main body 1, the ash hopper main body 1 is provided with a through hole 11, and the ash loosening device 2 includes a motor 21, an eccentric wheel 22 and a vibrating shaft 23, and the motor 21 is arranged on the ash hopper main body 1, the eccentric wheel 22 is set on the axis of the motor 21, one end of the vibrating shaft 23 passes through the through hole 11 and is set inside the ash hopper main body 1, and the other end is connected to the eccentric wheel 22 connection, the eccentric wheels of the multiple ash loosening devices are different, the motor 21 drives the eccentric wheel 22 to rotate, and the eccentric wheel 22 vibrates at different freq...

Embodiment 2

[0043] A method for loosening ash in an ash hopper provided with a vibrating ash loosening device, comprising the following steps:

[0044] Step 1. Debugging: Turn on the motor, the motor drives the eccentric wheel to rotate, and the energy generated by the eccentric movement of the eccentric wheel passes through the vibrating seat and the vibrating shaft in turn, and is transmitted to the main body of the ash hopper, so that the The main body of the ash hopper vibrates, and the vibration frequency is changed by adjusting the motor speed or the eccentric inertia of the eccentric wheel, so that the dust in the main body of the ash hopper resonates;

[0045] Step 2, loose ash: the relative movement between the dust in the main body of the ash hopper and between the dust and the main body of the ash hopper promotes the separation between the dust and the separation between the dust and the main body of the ash hopper, and the dust discharge from the bottom of the hopper body;

Abstract

The invention discloses an ash bucket with vibration ash loosening devices. The ash bucket comprises an ash bucket body and the ash loosening devices. The ash bucket body is of a conical structure, the ash loosening devices are arranged on the ash bucket body, and the ash bucket body is provided with a through hole. The ash loosening devices comprise motors, eccentric wheels and vibration shafts. The motors are arranged on the outer portion of the ash bucket body. The eccentric wheels are arranged on the axes of the motors. One end of each vibration shaft penetrates the through hole to be arranged in the ash bucket body, and the other ends of the vibration shafts are connected with the eccentric wheel. The eccentric wheels of the ash loosening devices are different, and are driven by the motors to rotate, and the eccentric wheels vibrate at different frequencies so that ash loosening can be carried out on dust in the ash bucket body. The invention further discloses an ash loosening method of the ash bucket with the vibration ash loosening devices. Resonant ash loosening of the ash bucket is achieved to the maximum degree through the steps of debugging, ash loosening and dynamic control.

Description

technical field [0001] The invention relates to the technical field of dust collectors, in particular to an ash hopper provided with a vibrating ash loosening device and an ash loosening method thereof. Background technique [0002] The ash hopper is the equipment for the dust removal and temporary storage of the electrostatic precipitator. Due to the failure of ash conveying and the characteristics of coal ash, the ash in the lower part of the ash hopper is easy to agglomerate, causing the ash hopper to be blocked, which has become a major threat to the safe operation of the electrostatic precipitator. Hidden danger. Ash hopper storage Conventional coal-fired power plant fly ash, the main components are SiO2, Al2O3, Fe2O3, CaO, MgO, Na2O, k2O, TiO2, SO3 and so on. In the prior art, mechanical agitation is often used for ash loosening, that is, a rigid stirring shaft is set at the outlet of the ash hopper, and the ash is agitated by a motor. However, due to the adhesiveness...
