Detailed Implementation

[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0019] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0020] Figure 1 and Figure 2 A schematic diagram of a filtration device for improving the filtration effect of rum according to a preferred embodiment of the present invention is shown. The filtration device includes two filter boxes, an inlet pipe 9, and an outlet pipe 19. (Reference) Figure 1 and Figure 2Each filter box has an inlet 7 at the top for feeding and an outlet 20 at the bottom for discharging. Each inlet 7 and outlet 20 is equipped with a valve 8 to open and close the corresponding inlet 7 and outlet 20. Both inlets 7 are connected to a feed pipe 9, which is connected to the rum supply equipment, allowing the rum to flow into the filter box. Both outlets 20 are connected to a discharge pipe 19, which is equipped with a transfer pump 18. The transfer pump 18 provides the driving force to transport the filtered rum from the filter box to the subsequent membrane filtration equipment for secondary filtration. In operation, one filter box is used to filter the rum, removing large particles and most small particles, before the rum is pumped by the transfer pump 18 to the membrane filtration equipment for secondary filtration. This avoids clogging the membrane filtration equipment and extends the downtime for membrane filter replacement. When the filter box in use becomes clogged, valve 8 of another filter box can be opened and valve 8 of the clogged filter box closed to replace or clean the filter bag 3. This allows for cleaning or replacement of the filter bag 3 without stopping the machine, improving work efficiency. Each filter box includes a box body 2, filter bags 3, and a stirring mechanism. The box body 2 has a cavity 1 inside, with an inlet 7 at the top and an outlet 20 at the bottom. The filter bag 3 has a filter chamber 10 with an open top. The filter bag 3 is detachably installed in the cavity 1 for easy replacement and cleaning, and the top opening of the filter bag 3 corresponds to the inlet 7. Rum supplied from the feed pipe 9 is fed into the filter chamber 10 through the inlet 7 for filtration. The filter bag 3 has multiple evenly distributed filter holes for filtering the rum. The stirring mechanism is installed in the filter chamber 10 to stir the rum inside. The stirring mechanism promotes the dissolution of sugar in rum, improving the filtration effect; it also agitates the rum, preventing impurities from clogging the filter holes and ensuring optimal filtration.

[0021] refer to Figure 1 and Figure 2 Preferably, the top of the cavity 1 has an opening, and the top opening is equipped with an openable and closable cover 5 for easy opening and closing of the filter box. The top of the filter bag 3 is equipped with an mounting ring 4, and the top of the cavity 1 has a recessed groove for mounting the mounting ring 4. The mounting ring 4 is inserted into the groove to install the filter bag 3, and the mounting ring 4 is pressed together after the cover 5 is closed to secure the filter bag 3. To remove the filter bag, simply open the cover 5 and lift it upwards; the assembly and disassembly method is simple and convenient.

[0022] refer to Figure 1 and Figure 2 The filter bag 3 can be conical, cylindrical, or frustum-shaped. Preferably, the filter bag 3 is cylindrical.

[0023] refer to Figure 1 and Figure 2 The stirring mechanism can be a rotary stirring structure or a vibratory stirring structure. Preferably, the stirring mechanism includes a rotating shaft 11, a first stirring rod assembly, and a motor 6. The rotating shaft 11 is installed inside the filter chamber 10, and the upper end of the rotating shaft 11 is rotatably connected to the top of the housing 2. Multiple first stirring rod assemblies are provided on the rotating shaft 11 along the vertical direction, and each first stirring rod assembly includes multiple first stirring rods 12 evenly distributed along the circumferential direction of the rotating shaft 11. The motor 6 is installed on the top of the housing 2, and the upper end of the rotating shaft 11 extends upward beyond the top of the housing 2. The output shaft of the motor 6 is connected to the upper end of the rotating shaft 11, and the motor 6 drives the rotating shaft 11 to rotate, thereby driving the first stirring rods 12 to rotate and stir the rum.

[0024] refer to Figure 1 and Figure 2 Preferably, the stirring mechanism further includes a second stirring rod 13 and a first brush 14. The outer end of the first stirring rod 12 is connected to the second stirring rod 13, and the length of the second stirring rod 13 is arranged in the vertical direction. There are at least two second stirring rods 13, which are arranged opposite each other. The outer side of the second stirring rod 13 is provided with the first brush 14, and the outer end of the first brush 14 contacts the side wall of the filter bag 3. Rotation of the shaft 11 drives the first stirring rod 12 and the second stirring rod 13 to stir the rum, while simultaneously driving the first brush 14 to rotate and brush the side wall of the filter bag 3, preventing debris from clogging the filter holes and further improving the filtration effect.

[0025] refer to Figure 1 and Figure 2 Preferably, the stirring mechanism further includes a third stirring rod 17 and a second brush 16. The third stirring rod 17 is installed at the lower end of the rotating shaft 11, and its length is distributed along the left-right direction. The bottom surface of the third stirring rod 17 is provided with the second brush 16, and the lower end of the second brush 16 is in contact with the bottom surface of the filter bag 3. When the rotating shaft 11 rotates, it drives the third stirring rod 17 to stir the rum while simultaneously driving the second brush 16 to rotate and brush the bottom surface of the filter bag 3, preventing debris from clogging the filter holes and ensuring the filtration effect.

[0026] refer to Figure 1 and Figure 2 The bottom surface of the filter bag 3 can be either flat or concave. Preferably, the bottom surface of the filter bag 3 has a dirt-collecting groove 15 recessed around its perimeter, meaning the bottom surface of the filter bag 3 is a convex frustum shape, with the perimeter of the frustum and the sidewall of the filter bag 3 forming the dirt-collecting groove 15. Through the action of the first brush 14 and the second brush 16, debris on the sidewall and bottom surface of the filter bag 3 can be swept into the dirt-collecting groove 15 for temporary storage, preventing clogging of the filter holes. This ensures both filtration efficiency and facilitates subsequent cleaning.

[0027] In use, open all valves 8 and motor 6 of one of the filter chambers, and start the delivery pump 18. Rum from the feed pipe 9 flows into the filter chamber 10 through the feed inlet 7 for filtration, removing large particles and most small particles. It then flows into the chamber 1 and is pumped by the delivery pump 18 to the subsequent membrane filtration equipment for secondary fine filtration to obtain clear juice. When the filter chamber 10 of this filter chamber becomes clogged with impurities, close the valve 8 of the feed inlet 7 and motor 6 of this filter chamber. Simultaneously, open all valves 8 and motor 6 of the other filter chamber. Rum from the feed pipe 9 enters the other filter chamber for filtration and is then pumped out by the delivery pump 18. After the delivery pump 18 has pumped all the rum from the chamber 1 of the previous filter chamber, close the valve 8 of the outlet 20 of that filter chamber, open the cover 5, clean or replace the filter bag 3 of the filter chamber. After cleaning or replacement, reinstall the cover 5 and filter bag 3 for later use. The filtration device of this invention can avoid clogging of membrane filtration equipment and extend the downtime for replacing membrane filter elements. Furthermore, when cleaning the filter box, only one filter box needs to be used, without shutting down the entire filtration production line, thus improving work efficiency.
