Referring to fig. 6 and 7, both ends of the second communication pipe 74 communicate with the third rod chamber 721 and the second rod chamber 621, respectively, and referring to fig. 8 and 9, a check valve 741 is installed to the second communication pipe 74, and liquid in the second rod chamber 621 can enter the third rod chamber 721 through the second communication. The second communication pipe 74 and the third rod chamber 721 are each provided with a liquid therein.
When sodium acetate is prepared, an operator injects sodium acetate solution prepared by reaction into the heating box 1 through the feeding pipe 11, the sodium acetate solution falls onto the second pressing plate 71, under the action of gravity of the sodium acetate solution, the third telescopic rod 72 compresses the third spring 73 to shrink, the third telescopic rod 72 shrinks to enable the volume in the third rod cavity 721 to increase, at this time, liquid in the second rod cavity 621 can enter the third rod cavity 721 through the second communicating pipe 74 under the action of gravity, the liquid volume in the second rod cavity 621 is reduced, and due to the fact that the second spring 63 is in a compressed state, the second telescopic rod 62 extends to enable the volume of the second rod cavity 621 to be reduced under the action of the second spring 63 until the volume of the second rod cavity 622 is increased until the remaining liquid in the second rod cavity 621 is filled, and at this time, a distance is reserved between the bottom end face of the movable end of the second telescopic rod 62 and the liquid level in the second rod cavity 622 because the liquid volume in the second rod cavity 622 is unchanged.
In the initial state, as the first spring 52 is always in the compressed state, the first spring 52 extrudes the movable end of the first telescopic rod 51, so that the first telescopic rod 51 extends, one end of the movable end of the first telescopic rod 51, which is far away from the fixed end of the first telescopic rod 51, is abutted against the pipe wall of the discharging pipe 12, and the two ends of the discharging pipe 12 are in the isolated state.
In the process of heating and concentrating the sodium acetate solution, the water collected in the collecting box 41 is gradually increased, the weight of the water on the first pressing plate 61 is gradually increased, and under the action of the gravity of the water, the first pressing plate 61 presses the second telescopic rod 62 downwards, so that the second telescopic rod 62 compresses the second spring 63 to shrink. During the contraction process of the second telescopic rod 62, after the bottom end surface of the movable end of the second telescopic rod 62 gradually contacts with the liquid in the second rodless cavity 622, the heating and concentration of the sodium acetate solution are completed. As the amount of the sodium acetate solution injected into the heating tank 1 increases, the time required for heating and concentrating the sodium acetate solution increases, and the amount of water vapor generated by heating and concentrating increases.
After the sodium acetate solution is heated and concentrated, as water vapor still enters the collecting box 41, the second telescopic rod 62 continues to shrink, so that the liquid in the second rodless cavity 622 is extruded to open the overflow valve 641, and then enters the first rod cavity 511 through the first communication pipe 64, so that the movable end of the first telescopic rod 51 is extruded to compress the first spring 52 to slide in a direction away from the discharging pipe 12, the two ends of the discharging pipe 12 are in a communicating state, and under the action of the water pump 121, the concentrated sodium acetate solution enters the discharging pipe 12 to be cooled and crystallized.
Since the amount of the sodium acetate solution injected into the heating tank 1 is different each time, the amount of contraction of the third telescopic rod 72 is different, so that the amount of the liquid entering the third rod cavity 721 from the second rod cavity 621 is different, and the more the amount of the sodium acetate solution injected into the heating tank 1 is, the more the amount of the liquid entering the third rod cavity 721 from the second rod cavity 621 is, the less the amount of the liquid in the second rod cavity 621 is, the longer the second telescopic rod 62 extends, the larger the volume of the second rod-free cavity 622 is, the larger the distance between the bottom end face of the movable end of the second telescopic rod 62 and the liquid level of the liquid in the second rod-free cavity 622 is, the longer the heating and concentrating time of the sodium acetate solution is, the more the water collected in the collecting tank 41 is, the bottom end face of the movable end of the second telescopic rod 62 and the liquid level of the liquid in the second rod-free cavity 622 can be contacted, the liquid in the second rod-free cavity 622 can be opened, the overflow valve 622 can be opened into the first rod cavity 641, the crystallizing valve 511 can be opened, and the sodium acetate solution can be cooled down by the communicating two ends of the communicating pipe 511, and the discharging pipe 12 can be cooled.
The implementation principle of the sodium acetate solid-liquid mixture centrifugal separation equipment provided by the embodiment of the application is as follows:
when sodium acetate is prepared, an operator injects sodium acetate solution prepared by reaction into a heating box 1 through a feeding pipe 11, an electric heating plate 13 is in a working state, heating and concentrating are carried out on the sodium acetate solution, after heating and concentrating are completed, the concentrated sodium acetate solution flows out through a discharging pipe 12 under the action of a water pump 121, the concentrated sodium acetate solution is cooled and crystallized through a cooling assembly 2 in the flowing process of the discharging pipe 12 to form a sodium acetate solid-liquid mixture, then the sodium acetate solid-liquid mixture enters a centrifugal barrel 31, and sodium acetate crystals and the sodium acetate solution are centrifugally separated through a centrifugal assembly 3, so that the sodium acetate preparation process is completed.
In the heating and concentrating process of the sodium acetate solution, the vapor generated in the heating and concentrating process is collected into the collection box 41 through the vapor collection assembly 4.
After sodium acetate solution is injected into the heating box 1, the detection assembly 7, the adjusting assembly 6 and the control assembly 5 are matched, so that the more sodium acetate solution is injected into the heating box 1, the longer the sodium acetate solution is heated and concentrated, the automatic control of the discharge pipe 12 is in a communicating state after the sodium acetate solution is heated and concentrated acid is completely ensured, and the concentrated sodium acetate solution enters the discharge pipe 12 for cooling and crystallizing.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
