[0031] See also Figure 1 and Figure 2 , which is a reactor 10 of an embodiment of the utility model, comprising a reactor body 100, a feed pipe 200, a stirring mechanism 300 and a concentrating mechanism 400, wherein a cover plate 110 is provided at the top of the reactor body 100, a fixing ring 120 is provided on the inner wall of the reactor body 100, a clearing valve 130 is provided on the side wall of the reactor body 100 adjacent to the fixing ring 120, and the clearing valve 130 is located above the fixing ring 120; the feed pipe 200 is located below the fixing ring 120, and the feed pipe 200 is penetrated through the reactor body 100; the stirring mechanism 300 comprises a stirring shaft 310 and a stirring paddle 320, and the stirring paddle 320 is located in the reactor body 100, and the stirring shaft 310 is penetrated through the cover plate 110 and connected to the stirring paddle 320; the concentrating mechanism 400 includes a sealed bearing 410, a first filter cloth 420, a pressure plate 430, a second filter cloth 440 and a pressure expander 450. The inner ring of the sealed bearing 410 is sleeved on the shaft body of the stirring shaft 310, and the sealed bearing 410 is arranged flush with the fixed ring 120. The inner circumferential wall of the first filter cloth 420 is sleeved and connected to the outer circumferential wall of the outer ring of the sealed bearing 410. The inner circumferential wall of the pressure plate 430 is sleeved and connected to the outer circumferential wall of the first filter cloth 420. The inner circumferential wall of the second filter cloth 440 is sleeved and connected to the outer circumferential wall of the pressure plate 430. The outer circumferential wall of the second filter cloth 440 is fixedly connected to the fixed ring 120. The pressure expander 450 is arranged on the cover plate 110, and the power expansion end of the pressure expander 450 is connected to the pressure plate 430.

[0032] In this embodiment, a cover plate 110 is provided at the top of the kettle body 100, a fixing ring 120 is provided on the inner wall of the kettle body 100, the stirring shaft 310 is passed through the cover plate 110, the inner ring of the sealing bearing 410 is sleeved on the shaft body of the stirring shaft 310, and the sealing bearing 410 is flush with the fixing ring 120, and the feed pipe 200 is located below the fixing ring 120, that is, the feed pipe 200 is located below the concentrating mechanism 400. First, the material enters the inner cavity of the kettle body 100 through the feed pipe 200. The material entering the kettle body 100 is located below the concentration mechanism 400. The material is stirred evenly by the stirring action of the stirring mechanism 300. When the material in the kettle body 100 reaches the preset liquid level, the pressure expansion device 450 is started, and the pressure expansion device 450 drives the pressing plate 430 to move toward the bottom of the kettle body 100. The material is compressed by the pressing plate 430, and the water in the material is filtered out through the first filter cloth 420 and the second filter cloth 440 and discharged by the clearing valve 130. When the pressing plate 430 reaches the set stroke, the pressure expansion device 450 retracts, that is, the pressure expansion device 450 drives the pressing plate 430 to move toward the cover plate 110, and the liquid level of the material in the reactor 10 is reduced, and the material is concentrated. At this time, there is a free liquid level in the kettle body 100, and appropriate materials are continued to be added to the kettle body 100 through the liquid inlet pipe, and then the above-mentioned concentration operation steps are repeatedly cycled until there is no free liquid level in the kettle body 100. It can be understood that by adjusting the extension and retraction frequency of the pressing plate 430 and the stroke of the pressing plate 430 , the liquid level in the kettle body 100 can be stably controlled.

[0033] In this embodiment, since a concentrating mechanism 400 is provided in the kettle body 100, the reactor 10 has the function of concentrating materials. Compared with the traditional method of combining a reactor 10 with a concentrator to concentrate materials, the reactor 10 disclosed in the present invention occupies a smaller space and has lower energy consumption; the reactor 10 disclosed in the present invention has a relatively simple structure and is easy to operate; the reactor 10 disclosed in the present invention can be obtained by modifying a conventional reactor and is easy to implement.

[0041] In one embodiment, the pressure telescopic device is a telescopic cylinder or a hydraulic telescopic rod.

[0042] In one embodiment, see Figure 2 The first filter cloth 420, the pressing plate 430 and the second filter cloth 440 are all concentric circle structures.

[0043] In one embodiment, see Figure 2 The number of the pressure expansion joints 450 is multiple, and the multiple pressure expansion joints 450 are evenly distributed on the pressing plate 430 with the stirring shaft 310 as the center. In this way, it is ensured that the pressing plate 430 is evenly stressed, so that the pressing plate 430 is better used to compress the material and improve the concentration effect of the material.

[0044] In one embodiment, see Figure 1 , the feed pipe 200 is provided with a check valve 210. Thus, by providing the check valve 210 in the feed pipe 200, it is prevented that when the pressure in the kettle body 100 changes, the material flows back through the feed pipe 200.
