[0034] The embodiments of the utility model will be described in detail below with reference to the drawings.

[0035] Referring to Figures 1-3 The embodiment discloses an overflow type tailing wastewater treatment system, in particular to a cyclone mainly used for recycling tailings, which comprises a cyclone body 101, a sand collecting nozzle 102, a fixing ring 103 and a connecting pipe 104 fixedly connected to the bottom end of the cyclone body 101, wherein the connecting pipe 104 is coaxially arranged with the cyclone body 101.

[0036] A limiting ring 105 is coaxially fixedly connected to the sand collecting nozzle 102, and a limiting groove 106 for fixing the sand collecting nozzle 102 after cooperating with the limiting ring 105 is arranged on the fixing ring 103; a threaded groove is arranged on the connecting pipe 104, and the fixing ring 103 is threadedly connected with the connecting pipe 104 through the threaded groove.

[0037] A connecting groove 107 is arranged on the connecting pipe 104, and a connecting convex ring 108 for cooperating with the connecting groove 107 is arranged on the sand collecting nozzle 102.

[0038] In the embodiment, when the solid phase particle size in the mixed phase entering the cyclone needs to be changed and the sand collecting nozzle 102 with different diameters needs to be replaced to achieve the best separation effect; the fixing ring 103 threadedly connected with the connecting pipe 104 is rotated until the fixing ring 103 is separated from the connecting pipe 104; the limiting groove 106 arranged on the fixing ring 103 moves away from the limiting ring 105 during the rotation process, and when the fixing ring 103 is separated from the connecting pipe 104, the limiting groove 106 no longer limits and fixes the limiting ring 105, at which time the sand collecting nozzle 102 can be quickly replaced; when the replaced sand collecting nozzle 102 needs to be installed on the connecting pipe 104, the connecting convex ring 108 is first moved into the connecting groove 107 and makes the connecting convex ring 108 contact with the connecting groove 107, and then the fixing ring 103 is installed on the connecting pipe 104 through the threaded groove; the fixing ring 103 is rotated to make the limiting groove 106 move towards the limiting ring 105 and abut against the connecting pipe 104, so as to fix the sand collecting nozzle 102; the cooperation of the connecting convex ring 108 and the connecting groove 107 can increase the contact area of the sand collecting nozzle 102 and the connecting pipe 104, so as to avoid the liquid in the cyclone body 101 from seeping out through the gap between the sand collecting nozzle 102 and the connecting pipe 104.

[0039] In some embodiments, the connecting groove 107 is provided with a first groove, and the first groove is fixedly connected with a first sealing ring 110. The first sealing ring 110 can seal the gap between the connecting groove 107 and the connecting convex ring 108.

[0040] In some embodiments, the first groove is a plurality of grooves, and the plurality of grooves are sequentially arranged in the connecting groove 107 from top to bottom. Each first groove is fixedly connected with a first sealing ring 110, and the first sealing rings 110 arranged from top to bottom can seal the gap between the connecting groove 107 and the connecting convex ring 108 in multiple levels.

[0041] In some embodiments, the connecting convex ring 108 is provided with a first protrusion 111 corresponding to the first groove. After the connecting convex ring 108 is moved to the position corresponding to the first groove, the first protrusion 111 can extrude the first sealing ring 110 installed in the first groove, and the first sealing ring 110 can further seal the gap between the connecting groove 107 and the connecting convex ring 108 after being deformed by the extrusion of the first protrusion 111.

[0042] In some embodiments, the cyclone body 101 includes a cone 112 and a cover 113 installed on the cone 112, and the connecting pipe 104 is fixedly connected to the bottom end of the cone 112. The cover 113 is connected with an inlet pipe 114 and an overflow pipe 115. After the mixed liquid to be separated enters the cyclone body 101 tangentially through the inlet pipe 114 at a certain pressure, the mixed liquid rotates in the cyclone and forms a three-dimensional elliptical strong rotational shear turbulent flow. This rotational motion can make different components in the mixed liquid receive different forces; because the coarse particles in the mixed liquid have a larger mass, they receive a larger centrifugal force, so they can overcome the hydraulic resistance to move to the wall and spiral downward along the wall under the action of their own gravity, and finally be discharged from the connecting pipe 104 to form sand. Fine and small particles and most of the water do not reach the wall and rotate with the liquid mixture because they receive a small centrifugal force. With the flow cross section of the liquid mixture becoming smaller and smaller, the inner layer of the liquid mixture containing a large number of fine particles has to change direction and move upward under the contraction pressure of the outer layer of the liquid mixture, forming an inner vortex and being discharged from the overflow pipe 115 to become overflow.

[0043] In some embodiments, the cover 113 is detachably connected to the cone 112 by bolts. By detachably connecting the cover 113 to the cone 112, the inside of the cover 113 and the cone 112 can be easily cleaned.

[0044] In some embodiments, the cone 112 is provided with a second groove, and a second sealing ring 116 is connected in the second groove. When the second sealing ring 116 contacts the inner wall of the cover 113, the second sealing ring 116 is deformed under the extrusion of the cover 113, thereby further sealing the gap between the cover 113 and the cone 112.

[0045] In some embodiments, the inner wall of the cover 113 is provided with a spiral rib 117. By providing the spiral rib 117, the mixed liquid entering the cover 113 in the tangential direction can be moved, so that the mixed liquid generates spiral flow, thereby improving the separation efficiency of the mixed liquid.

[0046] In some embodiments, the overflow pipe 115 is provided with a filter cartridge 109. The filter cartridge 109 is conical, and the open end of the filter cartridge 109 is downwardly arranged. By providing the filter cartridge 109, the large particles remaining in the inner rotational flow moving towards the overflow pipe 115 can be further filtered, thereby achieving better separation effect.

[0047] In some embodiments, the filter cartridge 109 is detachably connected with the overflow pipe 115. The overflow pipe 115 is provided with a threaded groove, and the filter cartridge 109 is threadedly connected with the overflow pipe 115 through the threaded groove, thereby facilitating replacement and cleaning of the filter cartridge 109.

[0048] Although the preferred embodiments of the present application have been described, those skilled in the art who have the basic inventive concept can make further changes and modifications to the embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0049] The above description is only the preferred embodiments of the present application and is not intended to limit the present application. It should be pointed out that any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
