Due to the use of the above-mentioned technical solutions, the present invention has the following advantages compared with the prior art:

1. The rotational vibration of the filter in the present invention refers to that the filter rotates back and forth within a certain range along its rotational axis, that is, vibrates in a torsional manner. Through this rotational vibration, the impurities on the surface of the filter material can be removed and the filter material can be prevented. clogged.

2. Since the vibrating device of the present invention changes the distance between the first pulley and the second pulley tensioned by the elastic member through the rotation of the eccentric wheel, the filter is centered on the rotation axis of the filter and the support. Turn and vibrate.

3. Since the vibration generated by the vibrating device of the present invention is in the tangential direction of the rotating shaft of the filter and the support, so the vibration has only torsional force to the rotating shaft of the filter and the support, and there is no radial force, which can reduce the vibration The impact on the rotating shaft can also reduce the impact of the vibration and noise of the entire equipment on the environment.

detailed description

The present invention will be further described below in conjunction with the embodiment shown in accompanying drawing:

Referring to shown in accompanying drawing 1-2, a kind of filtering device of rotating vibration, comprises support 1, the filter 2 that is arranged to rotate with support 1 and provides the vibration device that rotates and vibrates for filter 2, and vibration device includes rotating and is arranged on the filter The first pulley 4 on 2, the second pulley 5 set on the bracket 1, the transmission belt 6 sleeved on the first pulley 4 and the second pulley 5, connecting the filter 2 and the bracket 1 The elastic member for tensioning the drive belt 6 and the motor 7 to move the second pulley 5, wherein the second pulley 5 is an eccentric wheel, in other embodiments, the first pulley 4 can also be an eccentric wheel, or the second pulley 4 can be an eccentric wheel. One pulley 4 and the second pulley 5 are eccentric pulleys.

Referring to Fig. 3, due to the rotation of the eccentric wheel, the length of the conveyor belt changes, and the filter 2 vibrates in the direction of rotation under the tension of the elastic member.

There needs to be a certain distance between the first pulley 4 and the rotation axis of the filter 2 . The farther the distance is, the greater the torque will be, and the vibration will be more likely to occur. Therefore, the first pulley 4 is arranged outside the filter 2 .

The filtering device also includes a rotating shaft 3 vertically rotatably arranged on the support 1, and the filter 2 is fixedly arranged on the rotating shaft 3, wherein the rotating shaft 3 is parallel to the shaft of the first pulley 4 and the shaft of the second pulley 5.
