[0010] (1) The present invention provides a centrifugal filter that is easy to discharge material. It has a simple structure and is convenient and practical. The rotational force drives the lower cover to rotate, and the instantaneous rotational torque of the lower cover causes the lower cover to drive the screw to rotate. Thus, the screw moves along the screw until the lower cover contacts or separates from the filter ring, thereby achieving the purpose of material discharge or closing the filter ring for filtration.

Detailed Implementation

[0013] The embodiments of this utility model are further described below with reference to the accompanying drawings. Example

[0014] like Figures 1 to 4As shown; a centrifugal filter for easy discharge includes a fixed frame 1, a power unit 2, and a centrifugal filter device 3. The power unit 2 and the centrifugal filter device 3 are mounted on the fixed frame 1, and the power unit 2 is drivenly connected to the centrifugal filter device 3. The centrifugal filter device 3 includes a housing 31 and a filter device 32. The filter device 32 is disposed inside the housing 31 and is drivenly connected to the power unit 2. The filter device 32 includes an upper cover 36, a filter ring 37, an upper bearing 38, a connecting inclined plate 39, a rotating plate 310, a connecting frame 311, a connecting shaft 312, a lead screw 313, a lead rod 314, a rotating shaft 315, and a lower cover 316. The upper end of the filter ring 37 is connected to the upper cover 36. The upper cover 36 is connected to the housing 31 via the upper bearing 38. The rotating plate 310 is connected to the connecting shaft 312 via the connecting frame 311. Several connecting inclined plates 39 are connected between the connecting frame 311 and the inner wall of the filter ring 37. The connecting shaft 312 is connected to the rotating shaft 315 via a lead screw 314. One end of the rotating shaft 315 is connected to the power device 2 and movably connected to the fixed frame 1. The lead screw 313 is mounted on the lead screw 314. The lower cover 316 is connected to the lead screw 313 and engages with the lower end of the filter ring 37. Two positioning devices 317 are connected to the lead screw 314, and the positioning devices 317 engage with the lower cover 316. The positioning devices 317 include a lower bearing. 318 and contact sleeve 319, the contact sleeve 319 being connected to lead screw 314 via lower bearing 318; the outer shell 31 includes an outer shell ring 33, a feed pipe 34 and a U-shaped liquid guide groove 35, the top of the outer shell ring 33 being connected to the feed pipe 34 and the bottom being connected to the U-shaped liquid guide groove 35, the U-shaped liquid guide groove 35 being connected to a drain port; the filter ring 37 is conical; the side of the lower cover 316 that contacts the filter ring 37 is provided with a sealing layer.

[0015] The power unit 2 sequentially drives the rotating shaft 315, lead screw 314, connecting shaft 312, connecting frame 311, rotating plate 310, filter ring 37, and upper cover 36 to rotate. As the lead screw 314 rotates, the resistance of the lower cover 316 itself creates a speed difference between the lower cover 316 and the lead screw 314, causing the lead screw 313 to move along the lead screw 314 until the lower cover 316 contacts the contact sleeve 319 of its upper positioning device 317, and the sealing layer of the lower cover 316 contacts the filter ring 37, sealing the bottom of the filter ring 37. The filtrate is guided onto the rotating plate 310 through the feed pipe 34. The filtrate flows towards the connecting inclined plate 39 and the filter ring 37, where it is filtered. When the lower cover 316 is opened, the power device 2 drives the rotating shaft 315, the lead screw 314, and the connecting shaft 312 to rotate in reverse. This causes the resistance of the lower cover 316 itself to create a speed difference between the lower cover 316 and the lead screw 314, thus separating the lower cover 316 from the filter ring 37. The connecting inclined plate 39 and the filter ring 37 also rotate in opposite directions. The material attached to the filter ring 37 is guided to the lower cover 316 by the action of the connecting inclined plate 39. Centrifugal force causes the material on the lower cover 316 to be thrown out and fall, completing the material discharge.

For those skilled in the art, any equivalent modifications and substitutions to this utility model are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model are covered within the scope of this utility model.
