the utility model provides a filter equipment of rotational vibration, includes the support, with the support rotate the filter that sets up and for the filter provides the vibrating device of rotational vibration, vibrating device is including rotating the setting is in first band pulley on the filter, rotate the setting and be in second band pulley on the support, cover are established first band pulley with drive belt on the second band pulley, connection the filter with be used for the tensioning between the support elastic component of drive belt and wanting to move the actuating mechanism of second band pulley, first band pulley with at least one is the eccentric wheel.

Preferably, the filter device further comprises a rotating shaft rotatably arranged on the bracket, and the filter is fixedly arranged on the rotating shaft.

Further preferably, the rotation shaft is parallel to the shaft of the first pulley and the shaft of the second pulley.

Further preferably, the filter device is provided with a plurality of filters, wherein at least one filter is provided with the vibration device.

Preferably, the first pulley is disposed outside the filter.

Preferably, the filter comprises a housing and a plurality of sheet-shaped filtering membranes arranged in the housing, wherein the filtering membranes are perpendicular to the rotation axis of the filter.

Preferably, the elastic member is a tension spring.

Further preferably, the length direction of the tension spring is a tangential direction of rotation of the filter.

Preferably, the driving mechanism is a motor.

A filtration apparatus having the above-described rotary vibration filtration device.

Due to the application of the technical scheme, compared with the prior art, the invention has the following advantages:

1. the rotational vibration of the filter in the present invention means that the filter is rotated back and forth along its rotation axis within a certain range, that is, is vibrated in a torsional manner, and impurities on the surface of the filter medium can be removed by such rotational vibration, thereby preventing clogging of the filter medium.

2. Since the vibration device of the present invention changes the distance between the first pulley and the second pulley tensioned by the elastic member by means of the rotation of the eccentric, the filter is made to vibrate rotationally about its rotation axis with respect to the bracket.

3. The vibration generated by the vibration device is in the tangential direction of the rotation axis of the filter and the bracket, so that the vibration only has torsion force and no radial force on the rotation axis of the filter and the bracket, the impact of the vibration on the rotation axis can be reduced, and meanwhile, the influence of the vibration and noise of the whole equipment on the environment can be reduced.
