The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0017] Those skilled in the art should understand that, in the disclosure of the specification, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0018] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0019] refer to Figure 1 and Figure 2 , an embodiment of the present application provides a vibrating screen type solid-liquid separator, comprising a first base frame 10. A flywheel disc 11 and a rotating element 12 for driving the flywheel disc 11 to rotate in a directional manner are installed at the top of the first base frame 10, and a positioning hole 101 is provided on the rotating disc surface of the flywheel disc 11. A sieve plate assembly 20 is installed in the first base frame 10. The sieve plate assembly 20 includes a second base frame 21 and a solid-liquid separation frame 22, wherein the second base frame 21 is elastically connected to the solid-liquid separation frame 22 at the bottom, and a screen is provided at the bottom of the solid-liquid separation frame 22 for screening the liquid and retaining the solid in the screen, thereby realizing solid-liquid separation. In addition, a guide structure 23 is installed in the solid-liquid separation frame 22, wherein a crank connecting rod 31 is connected in a sliding manner in the guide structure 23, so that the crank connecting rod 31 can move in the guide structure 23 along the extension direction of the guide structure 23, and the other end of the crank connecting rod 31 is connected to the guide structure 23 in a hinged manner. At the positioning hole 101, when the flywheel disc 11 rotates, the solid-liquid separation frame 22 can be driven to vibrate back and forth up and down based on the matching relationship between the crank connecting rod 31 and the guide structure 23 and the elastic connection relationship between the solid-liquid separation frame 22 and the second base frame 21. The distance between the positioning hole 101 and the center of the flywheel disc 11 is different, and the up and down vibration amplitude of the solid-liquid separation frame 22 is also different. The key lies in the sliding matching relationship between the crank connecting rod 31 and the guide structure 23, so that the solid-liquid separator still has good vibration stability when it has a large vibration amplitude.

[0020] In simple terms, the rotating element 12 drives the flywheel disc 11 to rotate in a certain direction, and the positioning hole 101 on the rotating disc surface will make a circular motion with the center of the flywheel disc 11 as the center, thereby driving the crank connecting rod 31 to move back and forth in the guide structure 23. Since the solid-liquid separation frame 22 is elastically connected to the second base frame 21, the up and down reciprocating movement of the crank connecting rod 31 will cause the solid-liquid separation frame 22 to move elastically up and down, playing the role of vibration screening, so that the liquid is dried out and the solid remains on the screen. The key is that when the solid-liquid separator has a large amplitude, the sliding fit relationship between the crank connecting rod 31 and the guide structure 23 can make its vibration stability better. Generally, the solid-liquid separation frame 22 also has a relative feed port 201 and a solid discharge port 202, and the screen is located between the feed port 201 and the solid discharge port 202. After the liquid is screened, the solid is discharged from the solid discharge port 202.

[0021] In one embodiment, the rotating element 12 includes a rotating motor 121 and a coupling 122 , wherein the rotating shaft of the rotating motor 121 is connected to the axis of the flywheel 11 through the coupling 122 , so that the flywheel 11 can be driven to rotate precisely by the rotating motor 121 .

[0022] In one embodiment, there are four second base frames 21, and the four second base frames 21 are symmetrically distributed in a square shape on the outside of the first base frame 10, and the top of the second base frame 21 is connected to the solid-liquid separation frame 22 through a spring 24. The spring 24 plays the role of buffering the solid-liquid separation frame 22 and limiting the solid-liquid separation frame 22, and can also reserve sufficient space for the solid-liquid separation frame 22 to move up and down. In this way, during the vibration of the solid-liquid separation frame 22, the solid-liquid separation frame 22 can not only vibrate in the height direction, but also has a certain amount of movement space (within the spring elastic range) in the horizontal direction, and the vibration effect is better.

[0023] In one embodiment, there are multiple positioning holes 101, and the multiple positioning holes 101 are distributed on the rotating disk surface of the flywheel disc 11 in a clearance fit manner, and the multiple positioning holes 101 respectively maintain different distances from the disk center of the flywheel disc 11, so that when there are different amplitude requirements, the crank connecting rod 31 can be connected to the corresponding positioning hole 101, which is flexible and convenient to use. That is to say, the vibrating screen type solid-liquid separator provided in this application has the function of flexibly adjusting the amplitude, and the amplitude adjustment range is large and the vibration stability is good.

[0024] In one embodiment, the guide structure 23 extends obliquely in the solid-liquid separation frame 22 and faces the flywheel disc 11. In addition, a slider 231 is connected to the guide structure 23 in a sliding manner, and a connecting protrusion 232 is provided at the center position of the slider 231, and the crank connecting rod 31 and the connecting protrusion 232 are hingedly connected by a pin shaft, wherein the guide structure 23 is a guide groove that slides with the slider 231.

[0025] In one embodiment, the screen includes screen bars and brackets for connecting the screen bars to the solid-liquid separation frame 22, and the spacing between adjacent screen bars is 0.2 mm to 3.0 mm, which has a better screening effect especially for coal mine solid-liquid mixture.

[0026] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are provided for illustrative purposes only and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
