The feed inlet 1101 is connected to the mixing chamber 1104, the heavy phase outlet 1103 is connected to the clarifying chamber 1105, and the stirring assembly 140 is arranged in the mixing chamber 1104. In the chamber 1104, the stirring component 140 can mix the mixed liquid in the mixing chamber 1104, the buffer tube 130 is arranged around the outer peripheral wall of the tank body 110, one end of the buffer tube 130 is connected to the bottom of the mixing chamber 1104, and the other end of the buffer tube 130 is connected to the clarification chamber 1105. The mixed liquid enters the clarification chamber 1105 along the buffer tube 130. The side wall of the clarification chamber 1105 is also provided with a light phase outlet 1106, and the light phase outlet 1106 is located at the upper end of the clarification chamber 1105. The light phase extract floating on the upper end of the clarification chamber 1105 can be discharged from the light phase outlet 1106, and the unloading component 150 is connected to the heavy phase outlet 1103.

[0034] like Figures 2 to 4 As shown, further, the separation and collection structure 200 includes a conveying component 210, a separation and filtering component 220 and a box body 230, the separation and filtering component 220 includes a filter plate 221, a baffle 222 and a liquid partition plate 223, the box body 230 is provided with a heavy phase feed port 2301, a collection chamber 2302 and a solid discharge port 2303 which are connected in sequence, the feed assembly 150 is connected to the heavy phase feed port 2301, the liquid partition plate 223, the baffle 222 and the conveying component 210 are connected to the box body 230, and the liquid partition plate 223 divides the collection chamber 2302 into The liquid collecting tank 2304 and the solid collecting tank 2304, the solid collecting tank 2304 is connected to the solid discharge port 2303, the conveying component 210 is located between the heavy phase feed port 2301 and the liquid collecting tank 2304, the conveying component 210 can transport the mixture of the heavy phase extract and the calcium slag toward the baffle 222, one end of the baffle 222 abuts against the conveying component 210, one end of the filter plate 221 abuts against the baffle 222, and the other end of the filter plate is rotatably connected to the liquid partition plate 223, and the filter plate 221 can be used to filter the mixture of the extract and the calcium slag.

[0035] In this embodiment, the material and the extract are added into the mixing chamber 1104 from the feed port 1101 respectively, and the material and the extract are fully mixed by the stirring device. After the mixing is completed, the mixed liquid enters the buffer tube 130 from the mixing chamber, and the mixed liquid moves along the buffer tube 130 around the tank body 110 and enters the clarification chamber 1105. After the mixed liquid is left to stand, stratification occurs, the upper layer is the light phase extract, and the lower layer is a mixture of the relatively viscous heavy phase extract and calcium slag, and the light phase extract is discharged from the light phase outlet 1106. The mixture of heavy phase extract and calcium slag passes through the heavy phase outlet 1103, the feeding assembly 150 and the heavy phase feed port 2301 in sequence, and the mixture of heavy phase extract and calcium slag falls on the conveying assembly 210. The conveying assembly 210 moves the mixture of heavy phase extract and calcium slag toward the filter plate 221, so that the mixture of heavy phase extract and calcium slag falls on the filter plate 221. The baffle 222 abuts against the conveying assembly 210, so that the mixture of heavy phase extract and calcium slag remaining in the conveying assembly 210 is blocked by the baffle 222 and falls on the filter plate 221. The mixture of heavy phase extract and calcium slag is filtered on the filter plate 221, and the calcium slag is filtered out above the filter plate 221. The heavy phase extract passes through the filter plate 221 and flows into the liquid collection tank 2304. When the filtration is completed, the filter plate 221 is rotated so that the calcium slag falls into the solid collection chamber.

[0036] In the above-mentioned calcium slag separation and extraction device 10, the buffer tube 130 is respectively connected to the mixing chamber 1104 and the clarifying chamber 1105, and the buffer tube 130 is arranged around the outer peripheral wall of the tank body 110, so that the speed of the mixed liquid entering the clarifying chamber 1105 after passing through the buffer tube 130 is reduced, preventing the unevenly mixed mixed liquid from flowing into the clarifying chamber 1105 too quickly, thereby making the extraction effect of the extraction structure better; in addition, the mixing chamber 1104 and the clarifying chamber 1105 are arranged vertically, which reduces the footprint of the calcium slag separation and extraction device 10. The mixture of heavy phase extract and calcium slag enters the collecting chamber 2302 and falls on the surface of the conveying component 210. The conveying component 210 transports the mixture of heavy phase extract and calcium slag and causes it to fall on the surface of the filter plate 221. The baffle 222 cleans the mixture of heavy phase extract and calcium slag remaining on the conveying component 210 to the surface of the filter plate 221. The mixture of heavy phase extract and calcium slag on the filter plate 221 is filtered and separated, so that the operator can process the calcium slag in the solid collecting chamber 2305 and the operator can collect the heavy phase extract in the liquid collecting chamber 2304, thereby avoiding the blockage problem caused by the accumulation of calcium slag.

In this embodiment, the material is added to the mixing chamber 1104 from the feed pipe, and the extract is added to the mixing chamber 1104 from the feed pipe. The two feed ports 1101 speed up the speed of adding the material and the extract to the mixing chamber 1104, and avoid the problem of the mixed pipe contaminating the connecting pipe for adding the material.

[0038] In one embodiment, the extraction structure 100 further includes a valve member and a delivery pump, which are sequentially arranged on the buffer tube. In this embodiment, the valve member can open and close the channel in the buffer tube, thereby controlling the mixed liquid to flow into the clarification chamber 1105.

In this embodiment, the rotating motor 251 drives the connecting shaft 252 to rotate, and the connecting shaft 252 drives the filter plate 221 to rotate, so that the filter plate 221 flips over to the top of the solid collection tank 2304, and then the calcium slag on the filter plate 221 falls into the solid collection tank 2304, so that the calcium slag accumulated on the filter plate 221 is promptly processed, and the calcium slag affects the filtering effect of the filter plate 221.

[0045] like Figure 2 As shown, in one embodiment, the material discharge assembly 150 includes a material discharge assembly 151 and a first valve member 152, one end of the material discharge assembly 151 is connected to the heavy phase outlet 1103, the other end of the material discharge assembly 151 is connected to the heavy phase feed port 2301, and the first valve member 152 is installed on the material discharge assembly 151.
