The centrifugal cavity 40 is rotatably located in the inner space 11 of the cooling cavity 10 to ensure that the centrifugal cavity 40 can rotate relative to the cooling cavity 10, alternatively, in fig. 1 to 3, as an example, the centrifugal cavity 40 is arranged to extend in the up-down direction of the cooling cavity 10, so that the centrifugal cavity 40 stands up in the inner space 11 of the cooling cavity 10, and of course, according to actual needs, the centrifugal cavity 40 and the inner space 11 of the cooling cavity 10 may be designed into other positions, so that the utility model is not limited to those shown in fig. 1 to 3. The rotary driver 30 is configured to drive the centrifugal cavity 40 to rotate, so as to separate the solids 220 discharged from the solids discharge port 41 from the feed liquid entering the centrifugal cavity 40 through the feed liquid feeding pipe 50 and the solution 220 thrown to the internal space 11 of the cooling cavity 10 and discharged from the filtrate outlet 12, optionally, in fig. 1 to 3, as an example, the rotary driver 30 is located above the centrifugal cavity 40, and of course, the rotary driver 30 may be arranged at other positions as long as the rotary driver 30 can drive the centrifugal cavity 40 to rotate, which is not limited to fig. 1 to 3, according to actual needs. The heat exchange line 20 is assembled to the cooling chamber 10 and configured to exchange heat with the filtrate 210 at the inner space 11 of the cooling chamber 10 to meet the discharge requirement of the filtrate 210 in a preset temperature state. More specifically, the following is:

as shown in fig. 1 to 3, the feed liquid feed pipe 50 is exposed from the top 13 of the cooling chamber 10, the solid discharge port 41 is exposed from the bottom 14 of the cooling chamber 10, so that feed liquid is fed into the centrifugal chamber 40 from above, and the solid 220 is discharged from below the centrifugal chamber 40. Specifically, in fig. 1-3, as an example, the feed-liquid feed pipe 50 extends obliquely upward and protrudes beyond the top 13 of the cooling chamber 10 to facilitate feed-liquid entering the centrifugal chamber 40 along the feed-liquid feed pipe 50; the solids discharge port 41 extends downwardly and projects beyond the bottom 14 of the cooling cavity 10 to facilitate the discharge of solids 220 from the solids discharge port 41 out of the cooling cavity 10. More specifically, the feed-liquid feeding pipe 50 is fixedly connected to the top 13 of the cooling cavity 10, and the top 13 provides a supporting function for the feed-liquid feeding pipe 50, however, the feed-liquid feeding pipe 50 may be fixed at other positions according to actual needs, which is not limited thereto.

As shown in fig. 1 to 3, the heat exchange pipeline 20 is provided with a heat exchange liquid inlet 21 and a heat exchange liquid outlet 22, and the heat exchange liquid inlet 21 and the heat exchange liquid outlet 22 are respectively exposed from the side wall 15 of the cooling cavity 10. Specifically, in fig. 1 to 3, as an example, the heat exchange liquid inlet 21 and the heat exchange liquid outlet 22 are protruded from the side wall 15 of the cooling cavity 10, the heat exchange liquid inlet 21 is further located above the heat exchange liquid outlet 22, and the heat exchange liquid inlet 21 and the heat exchange liquid outlet 22 are further disposed on opposite sides of the side wall 15 of the cooling cavity 10, for example, the heat exchange liquid inlet 21 is located on the side wall 15 on the right side of the cooling cavity 10 and the heat exchange liquid outlet 22 is located on the side wall 15 on the left side of the cooling cavity 10, so that the design is convenient for the need of heat exchange liquid flowing from high to low. It should be noted that, since the heat exchange pipeline 20 is used for performing heat exchange with the filtrate 210 in the inner space 11 of the cooling cavity 10, the heat exchange liquid in the heat exchange pipeline 20 and the filtrate 210 in the inner space 11 of the cooling cavity 10 need to be separated from each other, and in order to separate the heat exchange liquid and the filtrate 210 from each other, a position of the heat exchange pipeline 20 between the heat exchange liquid inlet 21 and the heat exchange liquid outlet 22 is designed as a pipe body, and the pipe body is placed in the inner space 11 and is staggered with the centrifugal cavity 20; of course, the tube may be buried in the side wall 15 of the cooling chamber 10 and surround the inner space 11.

As shown in fig. 1 to 3, the centrifugal cavity 40 is cylindrical, and a plurality of separation holes are arranged on the side wall 42 of the centrifugal cavity 40 in a spaced manner; in addition, the cooling cavity 10 is cylindrical, and the center lines of the cooling cavity 10 and the centrifugal cavity 20 (see center lines in fig. 1 to 3) are coincident, so that the arrangement of the cooling cavity 10 and the centrifugal cavity 20 is more reasonable and compact; in addition, the filtrate outlet 12 is located adjacently beside the side wall 42 of the centrifugal chamber 40, and the bottom 13 of the cooling chamber 10 has a minor arc 141 in the inner contour cut by the plane of the center line of the supercooling chamber 10, so that the filtrate outlet 12 can discharge the filtrate 210 in the inner space 11 of the cooling chamber 10 more cleanly.

The working principle of the heat exchange type solid-liquid separation device 100 according to the present utility model will be described with reference to fig. 1 to 3:

When the separation is completed, the filtrate 210 is discharged from the filtrate outlet 12, and the solids 220 are discharged from the solids outlet 41, as shown in fig. 3.

Compared with the prior art, the heat exchange type solid-liquid separation device 100 of the utility model further comprises a heat exchange pipeline 20, a rotary driver 30, a feed liquid feeding pipe 50 and a centrifugal cavity 40 with a solid discharging hole 41, and the heat exchange pipeline 20, the rotary driver 30, the centrifugal cavity 40 and the cooling cavity 10 are matched, so that the heat exchange type solid-liquid separation device 100 of the utility model can also perform heat exchange treatment on the separated filtrate 210 after separating the filtrate 210 from the solid-containing solution, and the filtrate 210 discharged by the heat exchange type solid-liquid separation device 100 of the utility model is in a preset temperature state (such as a low temperature state or a high temperature state), so that an external heat exchanger is not needed for cooling (or heating); therefore, the heat exchange type solid-liquid separation device 100 can realize solid-liquid separation and filtrate heat exchange, reduce the process, reduce heat loss, reduce occupied area and cost, and improve treatment efficiency.

Note that, the direction indicated by arrow a in fig. 1 to 3 is the direction from bottom to top of the cooling cavity 10; in addition, the rotary driver 30 is preferably a motor, and can directly or indirectly drive the centrifugal cavity 40 to rotate; since the centrifugal cavity 40 needs to be rotated, at least one end (e.g., the upper or lower end) of the centrifugal cavity 40 is rotatably assembled with the cooling cavity 10, and the assembly requires a sealing process, as is well known in the art.

The foregoing disclosure is only illustrative of the preferred embodiments of the present utility model and is not to be construed as limiting the scope of the utility model, which is defined by the appended claims.
