[0033] Embodiment 2

[0034] like Figure 1-Figure 7 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0035] In this embodiment, the driving mechanism 3 includes a motor 31 fixedly mounted on the carrier frame 1, and the output shaft of the motor 31 is connected to the rotating shaft 21 through a bevel gear assembly 32. Specifically, the bevel gear assembly 32 includes two mutually meshing bevel gears, one of which is coaxially fixed to the output shaft of the motor 31, and the other is coaxially fixed to the rotating shaft 21.

[0036] When in use, the motor 31 is controlled to be turned on, and the output shaft of the motor 31 rotates to drive the rotating shaft 21 to rotate on the supporting frame 1 through the bevel gear assembly 32, thereby driving the extraction barrel 2 to rotate.

[0037] In this embodiment, the adjusting member 5 includes an adjusting rod 51 which is vertically and rotatably mounted on the mounting frame 43 , and the adjusting rod 51 is threadedly connected to the moving plate 432 .

[0038] When in use, the adjusting rod 51 can be rotated to drive the movable plate 432 to slide along the guide rod 431, which is easy to operate. Since the threaded connection between the adjusting rod 51 and the movable plate 432 is self-locking, the position of the movable plate 432 can be fixed without rotating the adjusting rod 51, which is easy to use.

[0039] Embodiment 3

[0040] like Figure 1-Figure 7 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0041] In this embodiment, the sealing assembly 8 includes: a sealing plate 81, a slot 74 connected to the interior of the separation box 7 is opened on one side of the separation box 7, the sealing plate 81 is inserted into the separation box 7 along the slot 74 and blocks the drop hole 72, and an electric push rod 82 connected to the sealing plate 81 is fixedly installed on one side of the separation box 7.

[0042] When in use, the electric push rod 82 is controlled to make the blocking plate 81 slide along the slot 74 toward the outside of the separation box 7, so that the blocking of the blanking hole 72 by the blocking plate 81 can be cancelled, which is convenient for control.

[0043] In the present embodiment, a cooling assembly 9 for cooling the interior of the extraction barrel 2 is installed on the extraction barrel 2; the cooling assembly 9 comprises: a cooling pipe 91; a mounting cavity 22 is opened on the top of the extraction barrel 2; the cooling pipe 91 is wound in the mounting cavity 22; the cooling pipe 91 is spirally wound in the mounting cavity 22; and the cooling pipe 91 is tightly fitted with the inner wall of the mounting cavity 22; a liquid pipe 1 92 and a liquid pipe 2 93 are fixedly installed at both ends of the cooling pipe 91, respectively; the ends of the liquid pipe 1 92 and the liquid pipe 2 93 both penetrate the outer wall of the extraction barrel 2; a rotating joint 1 94 and a rotating joint 2 95 respectively connected to the liquid pipe 1 92 and the liquid pipe 2 93 are symmetrically fixedly installed on the outer wall of the extraction barrel 2; a liquid inlet pipe 96 connected to the rotating joint 1 94 is fixedly installed on the support frame 1; a liquid outlet pipe 97 connected to the rotating joint 2 95 is fixedly installed on the support frame 1; and the liquid inlet pipe 96 and the liquid outlet pipe 97 are both connected to an external cooling liquid circulation device.

[0044] When in use, the motor 31 is controlled to be turned on to drive the extraction barrel 2 to perform centrifugal separation, and the external coolant circulation device is controlled to transport coolant to the liquid inlet pipe 96. The coolant flows into the cooling pipe 91 through the rotating joint 1 94 and the liquid pipe 1 92, and then flows back to the external coolant circulation device through the liquid pipe 2 93, the rotating joint 2 95 and the liquid outlet pipe 97 to achieve the coolant circulation effect. During this period, when the coolant flows in the cooling pipe 91, the extraction barrel 2 is cooled, thereby cooling the mixed solution in the extraction barrel 2, reducing the impurity suspension rate in the extraction barrel 2, and thus improving the centrifugal separation effect. Through the design of the rotating joint 1 94 and the rotating joint 2 95, when the extraction barrel 2 rotates, the rotating joint 1 94 and the rotating joint 2 95 themselves rotate, and will not drive the liquid inlet pipe 96 and the liquid outlet pipe 97 to rotate.

[0045] In this embodiment, the top cover 4 is fixed on the supporting frame 1 by screws, and the bottom of the top cover 4 is in contact with the top of the extraction barrel 2 .

[0046] By setting the top cover 4 to be fixed on the supporting frame 1 by screws, when the motor 31 works to drive the extraction barrel 2 to rotate, the top cover 4 will not rotate along with the extraction barrel 2, thereby reducing the load of the motor 31 and increasing the service life of the motor 31.

[0047] The working principle and use process of this utility model:

[0048] When extracting black rice:

[0049] The black rice raw material and the extract can be poured into the extraction barrel 2 through the feed port 41. After the black rice and the extract are mixed and extracted in the extraction barrel 2, the motor 31 is controlled to start and the rotating shaft 21 is rotated on the support frame 1, so that the extraction barrel 2 can be driven to rotate, and the mixture in the extraction barrel 2 is centrifuged to obtain an upper extract and a lower precipitate;

[0050] When the upper layer of the extract is to be drawn out for standby use, the control valve 1 64 is opened and the valve 2 65 is closed, and the adjusting rod 51 is rotated to make the movable plate 432 slide along the guide rod 431, driving the extension tube 45 to move downward, so that the bottom of the extension tube 45 moves to the place where the upper layer of the extract and the lower layer of the sediment are separated, and the control pump body 6 is opened, so that the upper layer of the extract can be drawn out through the corrugated hose 61 and the extension tube 45, and discharged through the connecting pipe 62, the three-way joint 63, the valve 1 64 and the discharge pipe 1 66, so that the upper layer of the extract can be collected for standby use;

[0051] When lower floor's sediment liquid is extracted out for standby use, control valve one 64 closes and valve two 65 opens, utilize adjusting member 5 to make movable plate 432 slide along guide rod 431, drive extension pipe 45 to shift downwards, make extension pipe 45 bottoms shift to lower floor's sediment liquid bottom position, control pump body 6 to open, can extract upper strata extracting solution out by corrugated hose 61 and extension pipe 45, and be transported in the separation box 7 by connecting pipe 62, three-way joint 63, valve two 65 and communicating pipe 67, discharge and collect for standby use by discharge pipe two 71 again, during this period, filter plate 711 filters black rice raw material, makes black rice raw material remain in separation box 7, effectively avoids the situation that black rice raw material and lower floor's sediment liquid are discharged together and causes black rice material waste;

[0052] After the lower sedimentation liquid is extracted, the electric push rod 82 is controlled to make the blocking plate 81 slide along the slot 74 to the outside of the separation box 7, so that the blocking of the blocking plate 81 to the blanking hole 72 can be cancelled, and the black rice raw material remaining in the separation box 7 can fall into the extraction barrel 2 through the blanking pipe 73, so as to achieve the recovery effect of the black rice raw material, and effectively avoid the situation that the quality of the extract is reduced when the black rice material in the extraction barrel 2 is subjected to secondary extraction;

[0053] Through the design of the cooling assembly 9, the motor 31 is controlled to be turned on, and when the extraction barrel 2 is driven to perform centrifugal separation, the external coolant circulation device is controlled to transport coolant into the liquid inlet pipe 96, and the coolant flows into the cooling pipe 91 through the rotating joint 1 94 and the liquid pipe 1 92, and then flows back to the external coolant circulation device through the liquid pipe 2 93, the rotating joint 2 95 and the liquid outlet pipe 97, so as to achieve the coolant circulation effect. During this period, when the coolant flows in the cooling pipe 91, the extraction barrel 2 is cooled, thereby cooling the mixed solution in the extraction barrel 2, reducing the impurity suspension rate in the extraction barrel 2, and thus improving the centrifugal separation effect; through the design of the rotating joint 1 94 and the rotating joint 2 95, when the extraction barrel 2 rotates, the rotating joint 1 94 and the rotating joint 2 95 themselves rotate, and will not drive the liquid inlet pipe 96 and the liquid outlet pipe 97 to rotate; by setting the top cover 4 to be fixedly installed on the support frame 1 by screws, when the motor 31 drives the extraction barrel 2 to rotate, the top cover 4 will not rotate with the rotation of the extraction barrel 2, thereby reducing the load of the motor 31 and improving the service life of the motor 31.
