The supporting mechanism 1 comprises an outer barrel 11, a base 13 is installed at the lower end of the outer barrel 11, a water outlet pipe 15 is installed at the axis position of the bottom of the outer barrel 11, a collecting frame 42 penetrates through the bottom of the outer barrel 11 and extends out of the outer barrel 11, a sealing cover 12 is installed at the upper end of the outer barrel 11, a water inlet pipe 14 is installed at the upper end of the sealing cover 12, and a water outlet of the water inlet pipe 14 corresponds to a water guide pipe 31.

The limiting rod 28 is connected to the bottom surface of the central support plate 5 through a bolt, the hollow cylinder is connected with the limiting rod 28 in a sliding mode, and the adjusting spring is connected with the hollow cylinder and the aligning cone cylinder 26 through welding.

A clamping plate is arranged between the ejector rod 46 and the reset spring, a reset limiting plate is fixed at the lower end of the cutting clamping plate on one side of the ejector rod 46, and the ejector rod 46 is connected with the reset limiting plate in a sliding mode.

As shown in fig. 1, a water inlet pipe 14 is connected with a water outlet pipe, waste water is introduced into a water conduit 31 through the water inlet pipe 14, a power rod 33 and a separating disc 34 in fig. 8 are rotated by a turbine blade in the water conduit 31 without power, after the waste water is rotated, the waste water is dispersed by the separating disc 34 and is thrown out through a water outlet 35 in fig. 4, the waste water is thrown on the inner wall of a filter cylinder net 21 because a scraping frame 41 is avoided, and the power gear 27 in fig. 6 is connected with the bottom of the power rod 33, so the power gear 27 transmits power to an inner matching gear ring 23 through a self-aligning cone 26, a lifting gear 25 and a central gear 24 in fig. 9, so that the inner matching gear ring 23 drives the filter cylinder net 21 to rotate, and when the waste water is thrown on the rotating filter cylinder net 21, particles are hung on the inner wall of the filter cylinder net 21;

when the filter cylinder net 21 continues to rotate, the side with the particulate matter rotates to the position corresponding to the cavity of the scraping frame 41, as shown in fig. 5 and 4, there is a gap at the side of the scraping frame 41 facing the rotating direction, so that the filter cylinder net 21 with the particulate matter is placed, after the filter cylinder net 21 with the particulate matter reaches the cavity, as can be seen from fig. 4 and 11, since the vibration transmission wheel 45 and the center rod 44 inside the scraping frame 41 are driven by the filter cylinder net 21 to rotate, and after the center rod 44 is matched with the salient points inside the vibration generation block 43 in fig. 14, the center rod 44 and the vibration transmission wheel 45 are vibrated by the salient points, so as to transmit the vibration to the filter cylinder net 21, the particulate matter attached to the filter cylinder net 21 is vibrated and gradually falls off the filter cylinder net 21, and falls into the cavity inside the scraping frame 41, and the bottom of the collection frame 42 is collected through the channel between the scraping frame 41 and the collection frame 42, and then the particulate matter falls off the side of the scraping frame 41 on the side far from the ejector rod 46, so as to ensure the effect of the particulate matter again;

when the filter cylinder net 21 is subjected to instantaneous large-flow wastewater to cause adhesion of large-batch particles, the filter cylinder net 21 sinks under the weight of the particles, as shown in fig. 10, the filter cylinder net 21 drives the lifting ring 22, the inner fit gear ring 23 and the aligning cone cylinder 26 in the subsequent fig. 10 to sink, after the aligning cone cylinder 26 sinks, the inner part and the hollow cylinder 29 sleeved with the limiting rod 28 are extruded, as shown in fig. 10, after the adjusting spring 29 is extruded in the direction of the power gear 27, the relative rotation radius of the aligning cone cylinder 26 is reduced at this time, the speed at which the power gear 27 drives the aligning cone cylinder 26 to rotate is increased, and the rotation speed of the filter cylinder net 21 is increased, then its cooperation vibrations pulley 45's speed becomes fast, thereby improve the clearance speed to filter cylinder net 21, and in the decline of lifting ring 22 simultaneously, according to fig. 7 can know, lifting ring 22 side corresponds ejector pin 46's bump extrusion bump, then strike off frame 41 and receive the side extrusion to take place rotatoryly around upset seat 47, then strike off frame 41 and be located ejector pin 46 one side gap grow, it is bigger to filter cylinder net 21 extrusion force to keep away from 36 one side of ejector pin, then filter cylinder net 21 that has thick particulate matter this moment is after great gap, shake and fall by the shock, strike off through the bigger one side of extrusion force again, guarantee to get rid of the effect, when collecting the inside bottom of frame and collecting when full, utilize and open the bottom baffle, collect the clearance.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
