Description

Technical Field

[0001] This application relates to the technical field of dust removal equipment, and in particular to a dust removal device for a beer filter aid bag breaking device. Background Technology

[0002] In current industrial beer production processes, candle filters are typically used for beer filtration. At different filtration stages, filter aids—diatomaceous earth or silica gel—need to be added continuously. Currently, the addition of filter aids is mostly done manually, by cutting open the bags and pouring the aid into the mixing tank. However, because diatomaceous earth particles are very fine, the process of emptying the bags easily generates a large amount of dust, posing a health hazard to workers.

[0003] Many existing bag-breaking machines and their systems are equipped with dust collectors to reduce dust. However, existing industrial dust collectors require regular manual cleaning, which increases labor costs and cannot meet the high hygiene standards and automation requirements of beer production. Therefore, developing a high-efficiency, low-maintenance dust collection device is particularly important. Utility Model Content

[0023] The following will be combined with the appendix Figure 1 - Appendix Figure 4 The technical solutions in the embodiments of the present invention are clearly and completely described herein. The described embodiments are only possible technical implementations of the present invention and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of the present invention without creative effort, and these embodiments are also within the protection scope of the present invention.

[0024] The inventors of this application have discovered that many existing bag-breaking machines and their systems on the market are equipped with dust collectors to reduce dust. However, existing industrial dust collectors require regular manual cleaning, increasing labor costs and failing to meet the high hygiene standards and automation requirements of beer production. Therefore, this application discloses a dust collection device for beer filter aid bag-breaking equipment, mainly employing the following solution:

[0025] This application discloses a dust removal device for a beer filter aid bag breaking equipment. (Refer to...) Figure 1 It includes a circulation tank 1 and a buffer tank 2. The buffer tank 2 is located above the circulation tank 1. The bottom of the circulation tank 1 is connected to a water supply pipe 11, which is connected to the top of the buffer tank 2. A circulation pump 12 is installed on the water supply pipe 11. The bottom of the buffer tank 2 is connected to a circulation pipe 21, which is connected to the top of the circulation tank 1. A bottom valve 22 is installed on the circulation pipe 21.

[0026] Reference Figure 2 , 3A venturi tube 3 is connected to the water supply pipe 11. The venturi tube 3 is connected to a dust suction pipe 4, which is used to connect to the inner cavity of the bag breaking machine. The venturi tube 3 includes an air inlet 31 and an air outlet 32 ​​located on both sides of the venturi tube 3, and an airflow channel 33 located inside the venturi tube 3. The airflow channel 33 is connected to the air inlet 31 and the air outlet 32 ​​respectively, and the inner diameter of the airflow channel 33 is smaller than the diameter of the air inlet 31 and the air outlet 32. The air outlet 32 ​​is connected to the water supply pipe 11, and the dust suction pipe 4 is connected to the airflow channel 33. Start the circulation pump 12 and open the bottom valve 22 on the circulation pipe 21 to allow the deoxygenated water to circulate at high speed between the circulation pipe and the buffer tank 2. When the water flows through the venturi tube 3, the high speed of the water flow will create a negative pressure in the venturi tube 3. Outside air will enter the water supply pipe 11 through the air inlet 31 and the airflow channel 33. When the outside airflow enters the airflow channel 33 through the air inlet 31, the reduced flow end face will cause the airflow to flow at high speed and create a negative pressure when passing through the narrow airflow channel 33. This will also create a negative pressure in the dust suction pipe 4, thereby efficiently sucking the floating dust in the inner cavity of the bag breaking machine into the dust suction pipe 4. The filter aid dust that enters the dust suction pipe 4 passes through the dust suction pipe 4 and the venturi tube 3 in sequence into the water supply pipe 11 and dissolves in the deoxygenated water.

[0027] Reference Figure 3 The Venturi tube 3 has an internal air chamber 34. The airflow channel 33 includes a first channel 331 and a second channel 332. The first channel 331 connects the air inlet 31 to the air chamber 34, and the second channel 332 connects the air chamber 34 to the air outlet 32. The side wall of the Venturi tube 3 has a connection port 35 that communicates with the air chamber 34, and the suction pipe 4 is connected to the connection port 35. The design of the air chamber 34 optimizes the airflow path within the Venturi tube 3, causing the airflow to form a vortex within the air chamber 34, thus enhancing the suction effect.

[0028] Reference Figure 3 The air chamber 34 contains a first protrusion 36 and a second protrusion 37. A first channel 331 passes through the first protrusion 36, and a second channel 332 passes through the second protrusion 37. A connecting seam 38 is provided between the first protrusion 36 and the second protrusion 37. The structural design of the first protrusion 36 and the second protrusion 37 in the air chamber 34 makes the airflow more stable when it enters the second channel 332 from the first channel 331, improving the speed and uniformity of the airflow. Furthermore, the connecting seam 38 between the first protrusion 36 and the second protrusion 37 effectively reduces the flow end face of the airflow, further enhancing the turbulence effect of the airflow and helping to improve the dust collection efficiency.

[0029] Reference Figure 3The air inlet 31 and the first channel 331 are connected by a conical connecting surface 39. The angle of the conical connecting surface 39 can be designed to be 15° to 30°. The design of the conical connecting surface 39 can effectively reduce the airflow resistance between the air inlet 31 and the first channel 331, improve the smoothness of airflow into the first channel 331, and thus enhance the suction effect of the venturi tube 3.

[0030] Reference Figure 3 The inner diameter of the first channel 331 gradually increases from the air inlet 31 toward the air chamber 34. This design allows the airflow to release some velocity before entering the air chamber 34 and increases the airflow volume, ensuring that the dust in the air chamber 34 can effectively enter the water supply pipe 11 along with the airflow, further improving the dust removal effect.

[0031] Reference Figure 3 The first channel 331 and the second channel 332 are directly opposite each other, and the inner diameter of the second channel 332 near the first channel 331 is larger than the inner diameter of the first channel 331. This design allows the airflow to flow smoothly inside the Venturi tube 3, ensuring the acceleration effect of the airflow. At the same time, the larger inner diameter of the second channel 332 near the first channel 331 facilitates the intake of dust from the air chamber 34 into the second channel 332.

[0032] Reference Figure 1 , 2 The top of the buffer tank 2 is connected to an exhaust pipe 23. In this application, there are two exhaust pipes 23. In other application embodiments, the number of exhaust pipes 23 can be set arbitrarily. By setting the exhaust pipes 23, the gas in the buffer tank 2 can be discharged through the exhaust pipes 23, avoiding excessive pressure caused by gas accumulation, and ensuring the safety and stability of equipment operation.

[0033] Reference Figure 2 The exhaust pipe 23 has a U-shaped design with its outlet facing downwards. The top of the circulation tank 1 is connected to a return water pipe 13, and the top of the return water pipe 13 is connected to a funnel 14. The outlet end of the exhaust pipe 23 is located above and connected to the funnel 14. Since the buffer tank 2 may carry out a small amount of moisture when venting, this design allows the moisture carried out by the gas during exhaust to flow back into the circulation tank 1 through the funnel 14 and the return water pipe 13.

[0034] Reference Figure 2 The funnel 14 is equipped with a dustproof net 15, which can effectively block large particles from entering the circulation tank 1 and protect the normal operation of the system.

[0035] Reference Figure 4The bottom of the buffer tank 2 is also connected to a water supply pipe 24. A valve 25 is installed on the water supply pipe 24. The deoxygenated water containing the filter aid dust dissolved in the circulation tank 1 can flow out through the water supply pipe 24. It can be used to rinse the dust remaining on the inner surface of the bag breaking machine or directly added to the filter aid mixing tank. There is no need for manual cleaning of dust regularly, which reduces labor.

[0036] The implementation principle of the dust removal device for a beer filter aid bag breaking equipment in this application embodiment is as follows: During use, the circulation pump 12 is started and the bottom valve 22 on the circulation pipe 21 is opened, so that the deoxygenated water circulates at high speed between the circulation pipe and the buffer tank 2. When the water flows through the venturi tube 3, due to the high speed of the water flow, a negative pressure is formed in the venturi tube 3. Outside air enters the water supply pipe 11 through the air inlet 31 and the airflow channel 33. When the outside airflow enters the airflow channel 33 through the air inlet 31, due to the reduction of the flow end face, the airflow will generate high speed when passing through the narrow airflow channel 33, and a negative pressure will be formed, so that a negative pressure is also generated in the dust suction pipe 4. Thus, the floating dust in the inner cavity of the bag breaking machine is efficiently sucked into the dust suction pipe 4. The filter aid dust entering the dust suction pipe 4 enters the water supply pipe 11 through the dust suction pipe 4 and the venturi tube 3 in sequence, and is dissolved into the deoxygenated water in the circulation tank 1, thereby achieving a highly efficient dust removal effect. Furthermore, the deoxygenated water containing the filter aid dust dissolved in the circulation tank 1 can be used to rinse the residual dust on the inner surface of the bag breaking machine or directly added to the filter aid mixing tank, eliminating the need for regular manual dust cleaning and reducing labor costs.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
