There is a small gap between the discs. The discs are driven by an electric motor through a transmission device and rotate at high speed with the drum. Due to the small gap between the discs and the small flow rate, the rotation of the milk liquid in the gap between the discs has a certain lag, and the material is easily unevenly distributed in the drum, which in turn affects the separation performance of the disc centrifuge. Utility Model Content

[0003] The utility model aims to provide a separation structure of a cream preparation centrifugal tank, which solves the problem that the rotation of milk liquid located in the gap between discs has a certain hysteresis and the material is easily unevenly distributed in the drum.

One end of the guide plate is connected to the outer cover, and the other end extends to the position of the truncated cone-shaped guide block of the distributor. The guide plate extends tangentially along the guide block and forms an annular channel on the periphery of the guide block.

[0006] Preferably, a guide column is arranged at the center of the distributor, the upper end of the guide column is hemispherical, and the guide column extends upward along the feed channel in the drum.

[0007] Preferably, a feed pipe connected to the feed channel is arranged on the top of the drum, the guide holes and feed holes arranged on the distributor and the disc form a milk rising channel, and a cream channel and a skimmed milk channel are also arranged in the drum cavity.

[0008] Preferably, the upper discharge port of the cream channel is connected to the cream discharge pipe, and a horizontal pipe, a lower slag discharge pipe and an inclined pipe are respectively arranged on one side of the cream discharge pipe connected to the cream channel along the cream discharge direction. The inclined pipe is arranged obliquely upward, and a filter is arranged on the upper end of the inclined pipe. The lower slag discharge pipe is connected to the bottom of the connecting position between the horizontal pipe and the inclined pipe, and a baffle is arranged in the horizontal pipe at the position corresponding to the lower slag discharge pipe.

[0009] Preferably, the upper discharge port of the skimmed milk channel is connected to the skimmed milk discharge pipe, and one side of the skimmed milk discharge pipe connected to the skimmed milk channel is respectively provided with a horizontal pipe two, a lower slag discharge pipe two and an inclined pipe two along the skimmed milk discharge direction.

[0010] The utility model has the following beneficial effects:

[0011] 1. The discs are provided with oblique ribs, and the gaps between the discs are small. The ribs are distributed in a spiral shape in the direction opposite to the rotation direction of the discs, and guide channels are formed between the ribs, which improves the problem of flow lag and uneven distribution of the milk liquid to be separated between the discs of each layer, and improves the centrifugal separation effect;

[0012] 2. A guide plate and an annular channel are arranged on the distributor. The guide plate guides the milk to the direction of the milk ascending channel. Part of the skimmed milk treated by centrifugation is discharged upward along the skimmed milk channel, and part of it spreads in the drum. The skimmed milk gathered in the drum at the annular channel plays a certain role in promoting the feeding of the milk, improving the circulation of the milk and increasing the fluidity of the liquid between the discs.

[0013] 3. A long guide column is set in the feeding channel to guide the milk liquid, so that the milk liquid can be distributed quickly and evenly;

[0014] 4. The cream discharge pipe and the skimmed milk discharge pipe are respectively provided with a filtering structure and a filter residue collection structure, which is beneficial to improving the quality of each component discharged and preventing the fine and light solid residue particles from being discharged from the residue discharge hole without being separated by centrifugal action, but being discharged with the flow of each component.
