[0001] The utility model relates to the technical field of beer brewing, and particularly relates to a whirlpool settling tank. Background Art

[0002] A whirlpool settling tank is an important device in the beer brewing process. It is generally cylindrical and is used for clarifying and separating wort. The principle is that the wort quickly enters the whirlpool settling tank and makes a decelerating swirling motion in the tank. By the way of whirlpool sedimentation, the hot coagulants in the wort are gathered and swirled at the bottom of the whirlpool tank, so as to achieve the purpose of clarification.

[0003] At present, for the traditional whirlpool settling tank, the discharge port on the whirlpool settling tank is opened only after the swirling motion of the liquid naturally decelerates to a standstill, and then the wort flows out. The time taken is relatively long and the production efficiency is low. Summary of the Utility Model

[0004] An object of the utility model is to solve the deficiencies existing in the prior art, and to provide a whirlpool settling tank that can improve the beer production efficiency without affecting the beer clarity.

[0009] A discharge cylinder, which is arranged on the tank body and communicated with the tank body, and the extending direction of the discharge cylinder is consistent with the tangential direction along the outer side wall of the tank body; when the wort makes a swirling motion in the tank body, the wort can flow out of the tank body along the extending direction of the discharge cylinder.

[0010] In an exemplary embodiment, the discharge cylinder comprises a first discharge cylinder and a second discharge cylinder. Along the axis direction of the tank body, the installation height of the first discharge cylinder is higher than that of the second discharge cylinder.

[0012] In an exemplary embodiment, the feed barrel is set at a height between the first discharge barrel and the second discharge barrel. After the wort enters the tank body through the feed barrel, the ratio between the liquid level of the wort entering the tank body and the diameter of the tank body is 1:0.7 to 1:0.75.

[0013] In an exemplary embodiment, the first discharge cylinder is disposed at one-half of the liquid level height.

[0014] In an exemplary embodiment, the second discharge cylinder is disposed at one tenth of the liquid level height.

[0015] In an exemplary embodiment, the angle between the extension direction of the feed cylinder and the tangent direction of the tank body is greater than 0 degree and less than or equal to 30 degrees.

[0016] In an exemplary embodiment, the angle between the extension direction of the feeding cylinder and the tangent direction of the tank body is 20 degrees.

It should be understood that the present invention can have various variations in different embodiments, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes and not intended to limit the present invention.

If the description of the positions of these elements changes, the indication of these directions also changes accordingly.

[0031] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0032] The present embodiment provides a whirlpool settling tank, which can effectively improve the production efficiency of beer without affecting the clarity of the beer. The specific solution is described through the following embodiments.

[0033] Please refer to Figure 1 , the whirlpool settling tank of the present embodiment includes a tank body 10, a feed cylinder 20 and a discharge cylinder 30.

[0034] Among them, the tank body 10 is cylindrical. The feed cylinder 20 and the discharge cylinder 30 are both arranged on the tank body 10 and communicate with the tank body 10, so that the wort can enter the interior of the tank body 10 through the feed cylinder 20 and flow out of the tank body 10 from the discharge cylinder 30.

[0035] It should be noted that the wort entering the whirlpool settling tank through the feed cylinder 20 has an initial velocity. After the wort enters the whirlpool settling tank, the wort makes a decelerating swirling motion in the whirlpool settling tank. The hot coagulants in the wort precipitate at the center of the whirlpool settling tank due to the vortex principle in the tea leaf paradox. Specifically, after the wort enters the whirlpool settling tank, an inverted conical vortex area will be formed at the center of the wort in the whirlpool settling tank. The hot coagulants in the upper layer of the wort in the whirlpool settling tank move towards the tank wall and the bottom of the tank body 10 under the action of centrifugal force and gravity. The hot coagulants in the lower layer of the wort in the whirlpool settling tank move towards the center continuously under the action of the centripetal force generated by supplementing the low-pressure area formed by the centrifugal action of the upper layer of the wort, so that the hot coagulants move gradually closer to the center of the tank body 10 while settling downward until they reach the vortex area, and the hot coagulants are quickly spun into the bottom, realizing the separation from the wort. And as the swirling progresses, the hot coagulants will gather in the center of the bottom of the tank, forming a cone with a thick middle and thin periphery.

[0036] The wort content loaded in the tank is related to the size of the tank body 10. In some embodiments, after the wort enters the tank through the feed pipe and the feeding is completed, the ratio between the liquid level height formed in the tank body 10 and the diameter of the tank body 10 is 1:0.7 to 1:0.75. The liquid level height herein refers to the liquid level height formed by the finally loaded wort in the tank after a single wort feeding.

[0037] In some embodiments of the present application, the top of the tank body 10 is conical. A manhole 40 is provided on the tank body 10. The manhole 40 is arranged at the top of the tank body 10. Users can observe the internal situation of the tank body 10 through this manhole 40.

[0038] Furthermore, the whirlpool sedimentation tank includes a lighting lamp 50. The lighting lamp 50 is also arranged at the top of the tank body 10 and is close to the manhole 40, which is more conducive to users observing the internal situation of the tank body 10.

[0039] See Figure 2 and in combination with Figure 1 , a first valve (not shown in the figure) is provided on the feed pipe 20. Opening the first valve allows the wort to enter the tank body 10 of the whirlpool sedimentation tank. When the wort enters the tank body 10 and the ratio between the liquid level height formed in the tank body 10 and the diameter of the tank body 10 is between 1:0.7 and 1:0.75, the first valve closes, indicating the end of the wort feeding.

[0040] Furthermore, the feed pipe 20 is arranged at one-third of the wort liquid level height. It should be noted that the feed pipe 20 is fixedly arranged on the tank body 10 and does not change with the change of the liquid level height formed by the wort entering the tank body 10.

[0041] In some examples, the axis of the feed pipe 20 and the section perpendicular to the axis of the tank body 10 are in the same plane. There is an angle between the extending direction of the feed pipe 20 and the tangential direction of the tank body 10, and the angle of this angle is greater than 0 degrees and less than 45 degrees.

[0042] In the traditional whirlpool sedimentation tank, the wort inlet enters the whirlpool sedimentation tank in the tangential inlet direction. When the wort enters from this inlet, it will directly impact on the tank wall of the tank body, resulting in partial loss of kinetic energy due to the friction of the tank wall, and causing the wort near the tank wall to interfere with the flow of the wort in the tank, forming local turbulence in the tank, which is not conducive to the precipitation of heat coagulants in the wort and affects the separation effect and clarity of the wort.

[0043] However, the setting of the feed pipe 20 in the present application enables the wort to enter the tank body 10 through the feed pipe 20 without directly impacting the inner wall of the tank body 10, effectively avoiding the loss of kinetic energy caused by the wort directly impacting the inner wall of the tank body 10, contributing to the swirling motion of the wort and the final formation of heat coagulants.

[0044] In some embodiments, the angle between the extending direction of the feed tube 20 and the tangential direction of the tank body 10 is greater than 0 degree and less than or equal to 30 degrees. The driving force formed by the wort swirling is greater than that formed by the angle greater than 30 degrees and less than 45 degrees. Therefore, it helps to increase the swirling speed of the wort and is beneficial to improving the separation rate of the wort and the hot coagulum.

[0045] Continue to refer to Figure 2 , in some embodiments of the present application, the angle of the included angle is 20 degrees, which is equivalent to the tangential direction of the tank body 10 deflecting 20 degrees away from the tank body 10. That is, the included angle between the extending direction of the feed tube 20 and the radius of the tank body is 110 degrees. Wherein, the radius of the tank body is the radius that intersects the connection point of the feed tube 20 and the tank body 10 on the plane perpendicular to the axis of the tank body 10.

[0046] The included angle formed by the feeding direction of the wort and the tangent of the tank body 10 is 20 degrees, effectively avoiding the loss of kinetic energy caused by the wort directly impacting the inner wall of the tank body 10. And the kinetic energy of the wort is the direct source of the swirling motion of the wort. Therefore, it can be understood that the structural setting of the feed tube 20 effectively maintains the initial kinetic energy of the wort entering the interior of the tank body 10, promotes the separation of the wort and the hot coagulum, and is beneficial to the final formation of the hot coagulum. In addition, the included angle formed by the feeding direction of the wort and the tangent of the tank body 10 is 20 degrees, which does not affect the swirling motion of the wort inside the tank body and is further beneficial to the separation of the wort and the hot coagulum.

[0047] The discharge tube 30 is fixedly arranged on the tank body 10. A second valve (not shown in the figure) is provided on the discharge tube 30. By opening the second valve, the wort can flow out of the tank body 10 through the discharge tube 30.

[0048] The axis of the discharge tube 30 is in the same plane as the section perpendicular to the axis of the tank body 10. In some examples, the extending direction of the discharge tube 30 is consistent with the tangential direction along the outer wall of the tank body 10. Equivalently, the wort can flow out of the tank body 10 along the tangential direction of the tank body 10. This setting enables the wort to flow out of the tank body 10 along the extending direction of the discharge tube 30 when the wort in the tank body 10 is not completely stationary.

[0049] Specifically, as the swirling progresses, the hot coagulum in the wort gradually settles and accumulates at the bottom center of the tank body 10. The user observes the internal situation of the swirling tank through the manhole 40. After observing that the swirling speed of the wort decreases, the second valve on the discharge tube 30 can be opened to allow the wort to flow out of the tank body 10 through the discharge tube 30.

[0050] It should be noted that a decrease in the swirling speed means that the wort is still swirling. At this time, the second valve on the discharge cylinder 30 is opened, and the outer-layer wort near the tank wall of the tank body 10 flows out of the tank body 10 along the extension direction of the discharge cylinder 30 with the swirling motion, which will not affect the swirling motion of the wort still in the tank body 10, and is equivalent to not affecting the final formation of the hot coagulum.

[0051] The discharge cylinder of the traditional whirlpool settling tank is designed with a straight outlet, that is, the outlet direction of the discharge cylinder is the same as the diameter direction of the tank body. This design causes some hot coagulum to flow out along with the wort when the wort flows out, and will affect the continuous swirling of the wort, thus affecting the clarity of the final beer. Therefore, the traditional whirlpool settling tank needs to wait until the wort decelerates to a standstill before opening the discharge cylinder to let the clarified wort flow out.

[0052] Therefore, the setting of the discharge cylinder 30 in this embodiment does not require waiting for the wort in the tank body 10 to decelerate to a standstill before opening the discharge cylinder 30 to let the wort flow out. Without affecting the separation efficiency and the clarity of the beer, it effectively saves time and improves the production efficiency of the beer.

[0053] Furthermore, the discharge cylinder 30 includes a first discharge cylinder 31 and a second discharge cylinder 32.

[0054] The installation height of the first discharge cylinder 31 is higher than that of the second discharge cylinder 32 to facilitate early discharging. Specifically, during the swirling motion of the wort, the upper liquid level far from the bottom of the tank body 10 will be clarified first. Therefore, the second valve on the first discharge cylinder 31 can be opened first to let the upper-layer wort flow out of the tank body 10 in advance.

[0055] Furthermore, the first discharge cylinder 31 is provided at the half of the liquid level height. The second discharge cylinder 32 is provided at the one-tenth of the liquid level height. It can be understood that the installation height of the feed cylinder is between the first discharge cylinder 31 and the second discharge cylinder 32.

[0056] Along the axial direction of the tank body 10, the first discharge cylinder 31 and the second discharge cylinder 32 are on the same straight line. That is, the connection line between the first discharge cylinder 31 and the second discharge cylinder 32, and the extension direction of this connection line is parallel to the axial direction of the tank body 10, so as to facilitate the connection with an external pipeline to uniformly collect the clarified wort into another container or enter the next brewing process.

[0057] The whirlpool settling tank further includes a collecting pipe. The collecting pipe is used to collect the wort located at the bottom of the tank body 10. In some embodiments, a plurality of outlets are opened at the bottom of the tank body 10. The plurality of outlets are arranged at intervals along the circumferential direction of the tank body 10. The collecting pipe is communicated with each outlet. The wort at the bottom flows out of the tank body 10 through the outlet and into the collecting pipe.

[0058] In some embodiments of the present application, the number of outlets may be three, and the three outlets are evenly distributed along the circumferential direction of the bottom of the tank.

[0059] Furthermore, the bottom of the tank body 10 is inclined from the axial direction of the tank body 10 to the circumferential direction of the tank body 10, forming a convex surface with a higher inner side and a lower outer side. The inclination angle is below 2 degrees. In some embodiments, the inclination angle may be 2 degrees. The inclined setting of the bottom of the tank body 10 facilitates the flow of the clarified wort to the outlet, and does not allow the formed hot coagulum to slide down and flow along with the wort, thus affecting the clarity of the wort.

[0060] See Figure 1 and in combination with Figure 3 As shown, the whirlpool sedimentation tank further includes a dispersing device 60, and the dispersing device 60 is used to disperse the finally formed hot coagulum and let it flow into the collecting pipe and out of the tank body 10.

[0061] Specifically, the dispersing device 60 is arranged at the center of the bottom of the tank body 10. The dispersing device 60 includes a water inlet pipe 61, a spray head 62 and a motor 63. The water inlet pipe 61 is communicated with the spray head 62, and external water can enter the spray head 62 from the water inlet pipe 61. The motor 63 is electrically connected to the spray head 62, and the motor 63 can cause the spray head 62 to rotate. Thus, driven by the motor 63, the rotation of the spray head 62 can disperse the finally formed hot coagulum covering the spray head 62. Then, by introducing external water, the external water is sprayed through the spray head 62, which can wash the hot coagulum and make it flow towards the outlet.

[0062] From the above technical solutions, it can be seen that the whirlpool sedimentation tank provided by this embodiment has the following advantages and beneficial implementation effects.

[0063] There is an included angle between the extending direction of the feeding cylinder 20 and the tangential direction of the tank body 10, which effectively maintains the initial kinetic energy of the wort entering the interior of the tank body 10, promotes the separation of the wort and the hot coagulum, and is beneficial to the final formation of the hot coagulum. The setting that the extending direction of the discharging cylinder 30 extends in the same tangential direction as the tank body 10 enables the user to collect the clarified wort in advance, and does not affect the swirling state inside the tank body 10, effectively saving time without affecting the clarity of the beer and improving the production efficiency of the beer.

[0064] The above embodiments are only illustrative examples of the structure. The structures in each embodiment are not fixedly combined structures. Without structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.

[0065] While the present utility model has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present utility model can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be construed broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
