The overflow port 17 is connected to the pipe. When the upper wellhead pressing filter screen device 1 is pressing the material, the excess liquid enters the pipe. The liquid in the pipe can be connected to the tank to recycle the fermentation liquid, or the liquid in the pipe can be stored separately to save the liquid for the next use of fermentation. The upper wellhead pressing filter screen device 1 includes an observation structure 14, a first connecting flange 15 and a filter pressing mesh screen 16; the observation structure 14 is installed on the top of the filter pressing mesh screen 16; the first connecting flange 15 is installed on the top of the filter pressing mesh screen 16 along the circumferential direction of the filter pressing mesh screen 16; the filter pressing mesh screen 16 of the upper wellhead pressing filter screen device 1 is a mesh screen all around, which is convenient for the liquid to enter the filter pressing mesh screen 16 during the pressing process, so that the liquid flows out from the overflow port 17.

[0036] When the fermentation material in the fermentation tank does not fill the fermentation tank, the pressing device cannot press the material into the liquid and submerge it. The circulating spraying device 9 is started. Since one end of the circulating liquid pipe 11 is connected to the tank, and the other end is connected to the first annular pipe 13, the liquid enters the circulating liquid pipe 11 and is sprayed out from the spray pipe on the first annular pipe 13. After the liquid hits the conical baffle 12, the liquid spraying and diffusion area increases, and the spraying is repeated in a continuous cycle to fully ferment the material suspended on the liquid surface.

[0037] like Figure 6 As shown, an auxiliary cleaning and discharging device 10 is installed on the tank body, and the auxiliary cleaning and discharging device 10 includes a liquid main pipe 20, a second annular pipe 21 and an outlet pipe opening 22; the liquid main pipe 20 is connected to the second annular pipe 21; a plurality of outlet pipe openings 22 are arranged on the second annular pipe 21, and the outlet pipe openings 22 are connected to the inside of the tank body; by allowing the cleaning liquid to enter the liquid main pipe 20, the cleaning liquid is sprayed from the plurality of outlet pipe openings 22 on the second annular pipe 21, so that the effect of quickly cleaning the inside of the tank can be achieved without manpower, and by allowing the fermentation liquid to enter the fermentation liquid main pipe 20, the fermented material can be quickly discharged from the discharging device under the flushing of the fermentation liquid.

[0039] The tank body includes an arc dome 3, a cylinder 4 and a lower cone 5; the upper part of the tank body is provided with an arc dome 3, and is connected to the cylinder 4; the lower part of the tank body is provided with a lower cone 5, and is connected to the cylinder 4; an inspection manhole 6 is provided on the cylinder 4, and the inspection manhole 6 can be opened and closed, so that people can enter the tank to clean and repair the tank conveniently.

[0040] Example 2

[0041] Based on Example 1, the use of the utility model for fermentation requires obtaining two fermentation products of different ages. First, the pump is connected through the feed circulation pipe 7 to convey the material and the fermentation liquid into the tank body. The staff observes the position reached by the material and the fermentation liquid from the pressing device; when the material and the fermentation liquid reach a position higher than the arc dome 3 and flood the middle position of the heightening circle 18, the material and the fermentation liquid are stopped from being conveyed into the tank. At this time, the upper wellhead pressing filter screen device 1 is used to press the material into the fermentation and make the material lower than the heightening circle 18. The fermentation liquid flowing out of the overflow port 17 is drained to a special storage place for the fermentation liquid through a pipe for the next fermentation; the upper wellhead pressing filter screen device 1 is fixed to the upper wellhead heightening device 2 by bolts, and the fermentation begins at this time.

[0042] When the fermentation time in the tank has reached the fermentation time of the first year, the discharge pipe 8 is connected to the pump, and the material is discharged from the tank through the discharge pipe 8 to complete the required amount of fermented material of the first year. The fermentation and discharge of the fermented material of the first year are completed, and the remaining fermented material and fermentation liquid in the tank continue to ferment the second fermented product with a longer required age; the remaining fermented material and fermentation liquid in the tank body do not completely fill the tank body, and the circulating spraying device 9 is turned on to allow the fermentation liquid to continue to circulate and spray so that the material floating on the fermentation liquid can also be fully fermented, and the fermentation is continued until the second fermentation product age is reached. At this time, the discharge pipe 8 is connected to the pump, and the auxiliary cleaning discharge device 10 is used to transport the fermentation liquid into the tank. The fermentation liquid flushes the fermented material, so that the discharge pipe 8 completely discharges the remaining fermentation material, completing the fermentation and discharge of the fermented product of the second age.

[0043] Finally, when all the fermentation and discharging processes are completed, the auxiliary cleaning and discharging device 10 is again used to transport cleaning liquid into the tank to clean the tank. The staff then enters the tank body through the inspection manhole 6 to check the cleaning status and maintenance of the tank body.

[0044] The above description is a detailed description of the preferred feasible embodiment of the present application, but the embodiment is not intended to limit the patent application scope of the present application.
