Description

Technical Field

[0001] This utility model relates to the technical field of beer brewing, specifically a diatomaceous earth filtration and purification device for beer brewing. Background Technology

[0002] Diatomaceous earth is used for purification in beer brewing. It plays a crucial role in the brewing process, primarily in the following ways: Filtration: During brewing, malt, water, and hops are mixed and boiled. After boiling, hop and malt fragments suspended in the liquid form turbidity, affecting the beer's taste and appearance. Diatomaceous earth, as a filter medium, effectively filters these impurities with its porous structure, resulting in a purer and clearer beer. Clarification: Filtered beer may still contain small amounts of turbidity, which can affect quality. Diatomaceous earth, as an additive, adsorbs these impurities during shaking and sedimentation, and through a screening process, makes the beer clear and transparent after freezing. Stabilizing Fermentation: Adding a small amount of diatomaceous earth to beer stabilizes the fermentation process, inhibits the growth of yeast and bacteria, and prevents spoilage. This additive is generally used in trace amounts and does not affect the beer's taste or quality. Currently, when using diatomaceous earth to filter and purify beer, the main method involves installing multiple filter plates within the machine. Through multi-stage filtration, the diatomaceous earth containing impurities can be filtered out. However, diatomaceous earth filtration and purification devices typically require disassembling the filter plates for cleaning before subsequent use. This disassembly method is cumbersome and not suitable for large-scale beer production. Therefore, we provide a diatomaceous earth filtration and purification device for beer brewing to solve the aforementioned problems. Utility Model Content

[0003] To solve the above problems, namely the problems mentioned in the background art, this utility model proposes a diatomaceous earth filtration and purification device for beer brewing, including a body, filter plates, a liquid injection pipe and a liquid drain valve. Multiple filter plates are fixedly installed in the inner cavity of the body. The liquid injection pipe is connected to the top side of the body, and the liquid drain valve is connected to the bottom of the side wall of the body.

[0004] The inner cavity of the machine body is equipped with a rotating drum. The top of the rotating drum is connected to a motor, and the bottom of the rotating drum is connected to a fan. The top two sides of the filter plate are provided with connecting pipes. The connecting pipes are provided with several air inlets on the side wall of the filter plate. The connecting pipes are all connected to the outer wall of the rotating drum. The bottom of the side wall of the machine body is connected to an air inlet valve.

[0005] Preferably, the output end of the fan is connected to a drain pipe, the motor is installed on the top of the machine body, the output end of the motor is connected to a reducer, and the output end of the reducer is fixedly connected to the top of the rotating drum.

[0006] Preferably, an air inlet of the connecting pipe is equipped with an air collection hood, and a solenoid valve is installed along the path between the air collection hood and the connecting pipe.

[0007] Preferably, the bottom end of the injection tube is connected to an annular tube, and a nozzle is fixedly installed at several openings at the bottom end of the annular tube. The annular tube is fixedly installed in the inner cavity of the machine body by a connecting rod.

[0008] The beneficial technical effects of this utility model are as follows: This filtration and purification device sets an air-suction connecting pipe above the filter plate and introduces diatomaceous earth into the drain pipe through a rotating drum. At the same time, the motor can drive the rotating drum to rotate, thereby allowing the connecting pipe to rotate and suck in air, so that the diatomaceous earth on the top of the filter plate can be fully absorbed, replacing the traditional cleaning method, thus making the filtration and purification of beer simpler and more efficient.

[0012] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0013] This utility model proposes a diatomaceous earth filtration and purification device for beer brewing, including a body 1, filter plates 2, a liquid injection pipe 3, and a drain valve 4. Multiple filter plates 2 are fixedly installed in the inner cavity of the body 1. The liquid injection pipe 3 is connected to the top side of the body 1, and the bottom end of the liquid injection pipe 3 is connected to an annular pipe 14. Several openings at the bottom end of the annular pipe 14 are fixedly installed with nozzles 15. This design avoids the liquid impacting the filter plates 2. The annular pipe 14 is fixedly installed in the inner cavity of the body 1 via a connecting rod 16. The drain valve 4 is connected to the bottom of the side wall of the body 1. A rotating drum 6 is rotatably installed in the inner cavity of the body 1. A motor 10 is connected to the top of the rotating drum 6 and is mounted on the top of the body 1. The output end of the motor 10 is connected to a reducer 11, and the output end of the reducer 11 is fixedly connected to the top of the rotating drum 6. The operation of the motor 10 can drive the rotating drum 6 to rotate at a low speed through the reducer 11. The bottom end of the rotating drum 6 is connected to... A blower 7 is connected to the filter plate 2, and a drain pipe 9 is connected to the output end of the blower 7. Connecting pipes 8 are provided on both sides of the top of the filter plate 2. Several air inlets are opened on the side wall of the filter plate 2 corresponding to the connecting pipes 8. Several connecting pipes 8 are connected to the outer wall of the rotating drum 6. A gas collection hood 12 is installed at the air inlet of the connecting pipe 8. A solenoid valve 13 is installed on the path between the gas collection hood 12 and the connecting pipe 8. An air inlet valve 5 is connected to the bottom of the side wall of the machine body 1. The operation of the blower 7 can draw air through the rotating drum 6, so that the connecting pipe 8 can draw air towards the filter plate 2 through the gas collection hood 12. At the same time, the rotating drum 6 can drive the connecting pipe 8 to rotate, realizing the revolution of the gas collection hood 12. Thus, the gas collection hood 12 can thoroughly clean the filter plate 2. Diatomaceous earth with impurities can be introduced into the collection box for collection through the blower 7 and the drain pipe 9. At the same time, the gas collection hoods 12 at the bottom of the corresponding two connecting pipes 8 are staggered, so that the filter plate 2 can be cleaned more thoroughly.

[0014] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0015] Working principle: When diatomaceous earth is needed to filter beer, the beer and diatomaceous earth can be mixed according to the ratio. Then, the beer containing diatomaceous earth is introduced into the injection pipe 3 by the delivery pump. At this time, the beer enters the nozzle 15 through the ring pipe 14 and is evenly sprayed onto the filter plate 2. The pore size of the four layers of filter plate 2 is set from top to bottom as 10μm-7μm-4μm-1μm. This design ensures the layer-by-layer filtration of large and small diatomaceous earth particles, avoiding the accumulation of diatomaceous earth. After filtration, the beer can be discharged through the opened drain valve 4. After filtration and purification, the motor 10 and fan 7 can be started, along with the solenoid valve 13 and air inlet valve 5. The motor 10 drives the rotating drum 6 to rotate at low speed via the reducer 11, while the fan 7 draws air through the rotating drum 6, allowing the connecting pipe 8 to draw air through the air collection hood 12 towards the filter plate 2. Simultaneously, the rotating drum 6 drives the connecting pipe 8 to rotate, achieving the revolution of the air collection hood 12. This allows the air collection hood 12 to thoroughly clean the filter plate 2. Diatomaceous earth containing impurities can be introduced into the collection box through the fan 7 and the drain pipe 9 for collection. After cleaning the filter plate 2, the wine can be filtered again with diatomaceous earth. This cleaning method eliminates the need to disassemble the machine body 1 and the internal filter plate 2, making the entire filtration and purification process simpler and more convenient.
