Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, and specifically, to a beer fermentation tank. Background Art

[0002] A fermentation tank refers to a device used for microbial fermentation in industry. Its main body is generally a main cylinder made of stainless steel plates. In the process of processing craft beer, the fermentation tank is an essential processing device.

[0003] For example, a fermentation tank for small-scale craft beer disclosed in a patent with the publication number CN218778904U includes a beer fermentation tank, and a liquid outlet pipe is fixedly installed in the middle of the lower end thereof. By providing a buffer pipe, a sedimentation pipe, a first filter cloth and a second filter cloth, when the craft beer is fermented in the fermentation tank, some sediment substances will fall to the bottom of the fermentation tank. The craft beer will successively pass through the first filter cloth and the second filter cloth in the buffer pipe to filter some sediment substances doped in the craft beer, avoiding impurities being easily mixed in the craft beer discharged first and reducing unnecessary waste. However, this fermentation tank has some deficiencies. In actual use, when the filter cloth is used for a period of time, it will accumulate a certain amount of impurities. If the filter cloth is not cleaned in time, it will cause blockage, resulting in relatively unsmooth discharge of beer. However, the filter cloth is installed at the bent part of the buffer pipe and the docking part of the buffer pipe and the liquid guide pipe, making the disassembly and assembly of the filter cloth relatively inconvenient, so it needs to be improved. Summary of the Utility Model

[0004] The purpose of the present utility model is to provide a beer fermentation tank to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present utility model provides the following technical solutions:

[0006] A beer fermentation tank includes a tank body. A fermentation chamber is arranged inside the tank body. A straight pipe communicating with the fermentation chamber is arranged outside the tank body and at the lower end part. A first valve for controlling the discharge of beer is arranged on the straight pipe. A connecting block is arranged at the outlet of the straight pipe. A through hole communicating with the straight pipe is formed on the connecting block. An outlet elbow pipe communicating with the through hole is arranged on the outer side surface of the connecting block. A slot penetrating the through hole is formed on the upper end surface of the connecting block. A detachable plug board is arranged in the slot. An installation hole adapted to the through hole is formed on the plug board. A filter net is arranged in the installation hole. A fixing component for fixing the plug board in the slot is arranged on the connecting block.

[0007] Further, the fixing component includes fixing columns symmetrically arranged on the side wall of the connecting block. A circular cavity is arranged inside the fixing column. A jack communicating with the slot is arranged on the side wall of the connecting block corresponding to the fixing column. A locking rod penetrating the jack and capable of extending into or disengaging from the slot is arranged in the circular cavity. A locking hole for the locking rod to extend into or disengage from is arranged on the plug board.

[0008] Further, a resisting ring is provided on the locking rod located in the circular cavity, an installation cap is provided at the opening end of the circular cavity in a threaded connection, a first spring for pushing the locking rod into the lock hole is sleeved on the locking rod between the resisting ring and the installation cap, one end of the locking rod extends out of the installation cap, and a pull rod for pulling the locking rod out of the lock hole is provided at the end of the locking rod extending out of the installation cap.

[0009] Further, a vertical arc-shaped hole communicating with the corresponding lock hole is provided on the insertion plate, and a second spring for pushing the insertion plate out of the insertion slot is provided at the bottom end of the insertion slot.

[0010] Further, a plug column is provided in the liquid outlet elbow pipe, a cavity is opened in the plug column, a liquid outlet is provided on the bottom wall of the cavity, a pipe body communicating with the liquid outlet is provided in the cavity, and a plurality of groups of liquid drainage grooves are opened on the side wall of the pipe body.

[0011] Further, a column is provided on the liquid outlet elbow pipe, a threaded hole is opened in the column, a rotating rod extending into the pipe body is provided in the threaded hole, and a blocking block located in the pipe body and used for controlling the opening size of the liquid drainage groove is provided at the lower end of the rotating rod.

[0012] Further, a slag discharge pipe communicating with the fermentation cavity is provided at the bottom of the tank body, and a second valve is provided on the slag discharge pipe.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. For this beer fermentation tank, the filter screen is installed by inserting the insertion plate into the insertion slot and fixing the insertion plate by the fixing component. After fermentation, the beer can flow through the filter screen and be discharged from the liquid outlet elbow pipe, so as to filter the discharged beer. When the filter screen is blocked and the liquid drainage is not smooth, first close the first valve to prevent the beer from flowing out of the fermentation cavity, then release the fixing of the insertion plate by the fixing component, pull out the insertion plate from the insertion slot, and the filter screen on the insertion plate can be cleaned after the insertion plate is pulled out.

[0015] 2. For this beer fermentation tank, through the arrangement of the vertical arc-shaped hole and the second spring, when the insertion plate is inserted into the insertion slot, the inclined surface at the lower end of the vertical arc-shaped hole can squeeze the locking rod, causing the locking rod to retract towards the insertion hole, so that the insertion plate can be inserted into the insertion slot. At the same time, the end of the locking rod is arc-shaped, enabling the end of the locking rod to slide better in the vertical arc-shaped hole, making the insertion of the insertion plate smoother. When the locking rod disengages from the lock hole, the second spring can push the insertion plate to pop out of the insertion slot partially, facilitating the removal of the insertion plate from the insertion slot.

[0016] 3. For this beer fermentation tank, through the arrangement of the column, the threaded hole, the rotating rod and the blocking block, when the fermented beer flows out of the liquid outlet, the rotating rod can be rotated to drive the blocking block to rise or fall in the pipe body, thereby controlling the opening size of the liquid drainage groove and further controlling the flow rate of the fermented beer flowing out of the liquid outlet.
