The support frame 2 can support the fermentation device 1 and other devices. The liquor after solid-liquid separation is allowed to flow into the purification container composed of two semicircular rings 6 at a selected rate through the liquid inlet mechanism 3. The two semicircular rings 6 together form an inner cavity for mixing liquor and activated carbon. The liquor and activated carbon are stirred by the stirring device 10. The activated carbon is allowed to fall into the purification container composed of the two semicircular rings 6 at a suitable rate through the stripping device 11. The liquor is filtered through the activated carbon collection device 12 and the purified activated carbon is collected and reused. The tightening component 7 fixes and seals the two semicircular rings 6. The liquor collection device 8 can store the purified liquor, and the liquor storage tank 9 is used to hold the purified liquor;

[0029] After fermentation, the liquor raw material passes through the fermentation device 1 to achieve solid-liquid separation and storage.

After purification, the liquor collecting device 8 collects the purified liquor and transfers it to the liquor storage tank 9. The remaining used activated carbon remains in the activated carbon collecting device 12. At this time, the two semicircular rings 6 are rotated outward by tightening the component 7 to take out the used activated carbon.

[0030] Specifically, in order to achieve the effect of fermentation and filtration of liquor by the fermentation device 1, please refer to Figure 1 In this solution, the fermentation device 1 includes a conical barrel 101, a lid 102 is slidably connected to the upper inner surface of the conical barrel 101, a plurality of layers of filter plates 103 are placed on the lower inner surface of the conical barrel 101, a columnar storage barrel 104 is fixedly connected to the lower end of the conical barrel 101, and a square hole is provided on the lower outer side of the columnar storage barrel 104;

[0031] During the implementation process, the lid 102 is opened, and the liquor to be filtered is poured into the conical barrel 101.

The speed of the driving motor 33 or the number of blades of the impeller 32 can be adjusted to control the transfer rate of the liquor;

[0034] The driving motor 1 33 drives the impeller 1 32 and the rotating shaft 1 34 to rotate, thereby driving the stripping device 11 to strip the material.

[0035] Specifically, in order to realize the function of adding activated carbon to the stripping device 11, please refer to Figure 4 In this solution, the stripping device 11 includes an impeller 111, which is located inside the square hole of the bottom wall of the shell 4. The rear end of the impeller 111 is fixedly connected to a rotating shaft 112, and the rotating shaft 112 passes through the shell 4 and extends to the outside. One end of the rotating shaft 112 is fixedly connected to the impeller 111, and the other end is connected to a belt 113 that is wound together with the rotating shaft 1 through a sliding wheel. The bottom wall of the shell 4 is fixedly connected to an activated carbon storage box 114, and the activated carbon storage box 114 is located just above the square hole of the bottom wall of the shell 4.

[0036] During the implementation process, under the action of belt 113, rotating shaft 1 34 and rotating shaft 2 112 rotate synchronously, thereby driving impeller 2 111 to rotate and put activated carbon into the purification cavity, i.e., stripping. When necessary, the blade ratio of impeller 1 32 and impeller 2 111 is adjusted to achieve the addition of activated carbon in a certain proportion to the liquor to maintain the taste of the liquor.

[0038] During the implementation process, the driving motor 2 1001 is turned on, the support rod 1002 and the stirring paddle 1003 begin to rotate, and the white wine and activated carbon in the purification chamber are stirred to achieve a full contact effect.

[0039] Specifically, in order to achieve the purpose of tightening the part 7 to fix and open the semicircular ring 6, please refer to Figure 4 and Figure 5 In this solution, the tightening component 7 includes two fixed clamping plates 71, and the two fixed clamping plates 71 are respectively fixedly connected to the adjacent semicircular rings 6, and the ends of the two fixed clamping plates 71 close to the support frame 2 are rotatably connected to the fixed plate 74, and the right end of the fixed plate 74 is fixedly connected to the support frame 2. The ends of the two fixed clamping plates 71 away from the support frame 2 are both provided with circular holes, and the inner surfaces of the two circular holes are threadedly connected with bolts 72;

[0040] During the implementation process, because the fixing clamp 71 is fixedly connected to the semicircular ring 6, the two fixing clamps 71 can be rotated to achieve the effect of closing or separating the two semicircular rings 6. When closing together, they are fixed by bolts 72 to ensure that the two semicircular rings 6 will not loosen during the purification process. When it is necessary to remove the activated carbon, the bolts 72 can be unfastened and the two closed semicircular rings 6 can be rotated to open them again. Specifically, in order to realize the function of the liquor collection device 8 to collect and transfer the purified liquor, please refer to Figure 3 In this solution, the liquor collection device 8 includes a liquor collection barrel 81, the right side of the liquor collection barrel 81 is fixedly connected to the support frame 2, a support plate 82 is fixedly connected to the lower part of the inner side of the liquor collection barrel 81, a petal-shaped hole 2 83 of the same size as the petal-shaped hole 1 124 is opened on the support plate 82, and the support plate 82 is attached to the lower end surface of the activated carbon collection barrel 122, and a handle square hole 84 adapted to the handle 125 is opened on the outer side of the liquor collection barrel 81, and a circular hole is opened on the lower end surface of the liquor collection barrel 81, and a liquid outlet pipe 85 is fixedly connected to the inner surface of the circular hole;

[0041] During the implementation process, the liquor flows into the liquor collecting barrel 81 through the petal-shaped hole 124, and then flows into the liquor storage tank 9 from the liquid outlet pipe 85.

[0042] Specifically, in order to realize the function of collecting activated carbon by the activated carbon collecting device 12, please refer to Figure 3 and Figure 4 In this solution, the activated carbon collection device 12 includes a plurality of connecting ropes 121, one end of the plurality of connecting ropes 121 is fixedly connected to the lower end of the housing 5, and the other end is fixedly connected to an activated carbon collection barrel 122, a plurality of layers of filter screens 123 are placed inside the activated carbon collection barrel 122, a petal-shaped hole 124 is opened on the bottom wall of the inner cavity of the activated carbon collection barrel 122, and a handle 125 is fixedly connected to the lower part of the outer side of the activated carbon collection barrel 122;

[0043] During the implementation process, the purified liquor will flow out from the petal-shaped hole 124, and the activated carbon will remain on the filter 123 in the activated carbon collection barrel 122 after purification. When the activated carbon needs to be taken out, the used activated carbon can be poured out by taking out the filter 123;

[0044] The handle 125 can rotate and fix the entire activated carbon collection barrel 122. Since the petal-shaped hole 124 and the petal-shaped hole 2 83 are of the same size and fit each other, the petal-shaped hole 124 starts to rotate when the handle 125 is rotated. If the petal-shaped hole 124 is aligned with the petal-shaped hole 2 83, the purified liquor can flow out. If the petal-shaped hole 124 is completely misaligned with the petal-shaped hole 2 83, the liquor cannot flow out.

[0045] When the liquor is stirred, the petal-shaped hole 124 is not aligned with the petal-shaped hole 83 to prevent the liquor from flowing out. After the liquor is purified, the handle 125 is rotated to align the petal-shaped hole 124 with the petal-shaped hole 83 to allow the purified liquor to flow out of the purification cavity and reach the liquor collection barrel 81.

[0046] It should be noted that the specific installation method, circuit connection method and control method of the drive motor 1 33 and the drive motor 2 1001 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
