A solid-liquid separation device 100 for zinc oxide production includes an overflow tank 110, the material of which can be rust-resistant stainless steel, and its shape and size can be set according to actual use requirements. The overflow tank 110 can also be supported on the ground by setting a supporting component. A sedimentation cylinder 120 is connected to the bottom central axis of the overflow tank 110, and the sedimentation cylinder 120 is used for zinc oxide particles and liquid water to be layered inside after standing. The bottom of the sedimentation cylinder 120 extends to the outer end of the overflow tank 110 and is provided with a discharge valve 121, and the discharge valve 121 here can be a sealed gate valve. The top of the sedimentation cylinder 120 is located in the inner cavity of the overflow tank 110 and is connected to a belt reel 130, which can be made of a water-proof cortical material, and is connected to the sedimentation cylinder 120 as a whole. A feeding trough 111 is provided at the top of the overflow tank 110, and a feeding pipe 112 is connected to the bottom of the feeding trough 111. The feeding pipe 112 extends to the inside of the belt reel 130. The zinc oxide liquid to be separated is added from the feeding trough 111 and enters the belt reel 130 and the sedimentation cylinder 120 through the feeding pipe 112. A fixing ring 131 is connected to the outer periphery of the top of the belt reel 130. The fixing ring 131 is used to open the top of the belt reel 130 so that the mouth of the belt reel 130 with a relatively soft texture can maintain an open state. A support ring 132 is provided at the bottom of the fixing ring 131, which is located at the outer periphery of the belt reel 130. The support can also be further fixed by supporting the fixing ring 131 to pull the belt reel 130 upward as a whole, so that the belt reel 130 is in a relatively stable state. The support ring 132 is connected with a plurality of telescopic components 140, which are connected to the inner bottom wall of the sedimentation cylinder 120. The telescopic components 140 can drive the support ring 132 to rise or fall. A plurality of winding drums 113 are arranged on the top of the overflow tank 110, and a plurality of fixed pulleys 114 corresponding to the winding drums 113 are arranged on the bottom of the sedimentation cylinder 120. A plurality of traction lines 115 are connected to the fixed ring 131, and the plurality of traction lines 115 are connected to the winding drum 113 after passing through the plurality of fixed pulleys 114. The winding drum 113 will pull the traction lines 115 during its rotation, and the traction lines 115 will be pulled up and wound around the outer periphery of the winding drum 113.
[0020] In the embodiment of the present application, during the specific working process, the zinc oxide liquid to be separated is added along the feeding trough 111, and then the zinc oxide mixed liquid enters the belt reel 130 and the sedimentation cylinder 120 through the feeding pipe 112. After standing for a period of time, the zinc oxide and the liquid water are separated into layers, the zinc oxide is located at the bottom of the sedimentation cylinder 120, and the water is located at the top. At this time, the telescopic component 140 and the winding drum 113 are synchronously opened. During the downward shortening of the telescopic component 140, the support ring 132 moves downward, and the winding drum 113 rotates and pulls The traction line 115 changes the direction of force through the fixed pulley 114 and then pulls the belt reel 130 downward, and then the belt reel 130 flips outward and then flips downward with the support of the support ring 132. At this time, the liquid water on the upper part of the belt reel 130 overflows into the overflow tank 110, and the winding drum 113 and the telescopic assembly 140 reset after working for a period of time. At this time, most of the water in the sedimentation cylinder 120 has been separated, and the discharge valve 121 is opened to discharge the zinc oxide in the sedimentation cylinder 120.
[0021] As can be seen from the above, in the embodiment of the present application, by setting the sedimentation cylinder 120 and the belt reel 130, when the zinc oxide mixed liquid enters the inside and precipitates, the belt reel 130 can be folded down and then moved down, so that the liquid water at the top of the belt reel 130 can overflow into the overflow tank 110, thereby efficiently completing the separation operation of zinc oxide and liquid water, and the whole process is simple and convenient to operate, suitable for large-scale operations. In the embodiment of the present application, a support ring 132 and a telescopic assembly 140 are also set, and the telescopic assembly 140 can drive the support ring 132 to rise or fall, and the support ring 132 is covered on the outside of the belt reel 130 to provide a fulcrum for the flipping of the belt reel 130. At the same time, the setting of the traction line 115, the fixed pulley 114 and the winding drum 113 can steadily apply multiple downward pulling forces to the belt reel 130, so as to facilitate the flipping of the belt reel 130.
[0022] In some embodiments, a dehydration conveyor 150 is provided at the bottom of the sedimentation cylinder 120.
