Problems solved by technology

[0004] If the material is stored for too long, the viscosity of the material will increase due to the absorption of moisture in the air, which will cause the material to easily stick, and then the material will accumulate and cause blockage
[0005] The material falls from a high place, if the depth of the hopper is deeper, the speed of the material reaching the outlet of the hopper will be greater, and the subsequent material will be compacted, resulting in blockage
[0006] If mixed with debris, the debris may cause blockage of large pieces of material, causing blockage

Embodiment 1

[0143] Embodiment 1: numerical analysis

[0144] The steady-state phase relationship of the system consists of three phase relationships, namely the phase difference between the exciters, the phase relationship between the system response and the exciters, and the phase relationship between the system responses.

[0145] Assume that the vibration system parameter is k 1y =k 2y =14000kN / m,k 3y =16000kN / m,k 4y =10kN / m, m 1 = m 2 =1400kg, m 3 =1600kg, m 01 = m 02 =10kg, M 4 = m 4 +m 01 +m 02 =2020kg, the natural frequency of the system can be obtained by calculation, point A: ω 1 =100rad / s, point B: ω 2 = 178.27 rad / s.

[0146] Therefore according to ω 1 = 100rad / s and ω 2 =178.27rad / s can be divided into three zones: Zone 1 is ω m0 1 , zone 2 is ω 1 m0 2 , zone 3 is ω 2 m0 .

[0147] figure 2 Indicates the phase angle relationship between the two exciters, 2α is the phase difference between exciters 1 and 2, when the excitation frequency is in zone 1, the p...

[0153] Embodiment 2: Simulation of vibration system

[0154] The simulation of the vibration system mainly uses the fourth-order Rouge-Kutta program for simulation, and simulates one by one according to the three areas previously divided. In practical engineering applications, the same exciter is generally used, and the parameters of the four motors are the same, that is, η = 1.0. The overall parameters of the system are selected as follows: rotor resistance R r =3.40Ω, stator resistance R s =3.35Ω, rotor inductance L r =170mH, stator inductance L s =170mH, mutual inductance L m =164mH,f 1y =f 2y = 0.05. Other parameters of the vibration system: r = 0.15m, m 1 = m 2 =1400kg, m 3 =1600kg, m 01 = m 02 =10kg, M 4 = m 4 +m 01 +m 02 =2020kg, adjust the parameters to make the system in sub-resonance state and super-resonance state respectively.

[0155] Simulate region 1, assuming k 1y =k 2y =40000kN / m,k 3y =10000kN / m,k 4y =10kN / m,z 1 =0.609:

[0177] A self-synchronized drive anti-clogging vibrating feeder. Its dynamic model see figure 1 , including: exciter m 0i (i=1~2), plastid m i (i=1~4), spring k i (i=1~4). The model consists of two shakers and four masses. Plastids 1 and 2 move oppositely in the horizontal direction, and plastids 3 and 4 have no displacement in the x direction. And each vibrator rotates around its own axis of rotation to express.

[0178] The following are example data parameters for one of the vibratory feeders designed using this invention. The invention is not limited to this design parameter.

[0179] Spring rate: k 1y =k 2y =8000kN / m,k 3y =10000kN / m,k 4y =10kN / m;:

Description

technical field [0001] The invention belongs to the technical field of vibrating feeding devices, and relates to a self-synchronously driven anti-blocking vibrating feeding machine and a parameter determination method thereof. Background technique [0002] Vibrating feeder, also known as vibrating feeder, refers to a kind of equipment that can uniformly, regularly and continuously feed bulk and granular materials from the storage bin to the receiving device. Widely used in metallurgy, coal mine, building materials, chemical industry and other industries. The vibrating feeder has the advantages of simple structure, uniform feeding, good continuity, and adjustable exciting force. [0003] The present invention is different from other vibrating feeders. Ordinary vibrating feeders are prone to clogging during the working process. The main reasons for the clogging are as follows: [0004] If the material is stored for too long, the viscosity of the material will increase due to...
