[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 5 , and the above technical solutions will be described in detail through the following embodiments of the present invention:

[0026] A filtering device suitable for white wine brewing includes: a filter box 1; a feeding pipe 2 is arranged on one side of the filter box 1, one end of the feeding pipe 2 penetrates through the filter box 1 and extends to the inside of the filter box 1, an annular plate 3 is arranged inside the filter box 1, a discharge hole 4 is opened at the center of the annular plate 3, a partition board 5 is fixedly connected to the outer surface of the annular plate 3, and a drain pipe 6 is fixedly connected to the filter box 1 near the partition board 5; a separation mechanism 7 for filtering white wine and distiller's grains is arranged on the outer surface of one end of the feeding pipe 2 located inside the filter box 1; an extrusion mechanism 8 for efficiently separating the white wine adsorbed in the distiller's grains is arranged inside the annular plate 3. The user uses a conveying device to convey white wine from the feeding pipe 2 into the filter box 1, and the separation mechanism 7 inside the filter box 1 separates the white wine and impurities. The separated impurities accumulate at the discharge hole 4 inside the annular plate 3. As the accumulation of impurities increases, when the impurities accumulate to a certain extent, the extrusion mechanism 8 extrudes the impurities accumulated inside the discharge hole 4, and the white wine extruded from the impurities continues to be filtered through the separation mechanism 7. The user can separate the white wine from the impurities in the white wine and extrude the separated impurities, thereby improving the separation effect of the white wine and the impurities in the white wine, and solving the problem that although the existing filtering device for white wine brewing is convenient for replacing and cleaning diatomaceous earth and can filter and separate white wine and the impurities inside the white wine, the water absorption of the impurities inside the white wine is large, resulting in a small amount of white wine still remaining in the separated impurities, making the separation effect of the white wine and the impurities poor.

[0027] As Figure 3 shown, the separation mechanism 7 includes: One end of the feeding pipe 2 located inside the filtering box 1 is fixedly connected with an outer surface of a first annular filter screen 9. A second annular filter screen 10 is arranged outside the first annular filter screen 9. The second annular filter screen 10 is fixedly connected with the feeding pipe 2. Filtering materials 11 are filled between the second annular filter screen 10 and the first annular filter screen 9. The tops of both the first annular filter screen 9 and the second annular filter screen 10 are fixedly connected with the filtering box 1. The bottoms of both the first annular filter screen 9 and the second annular filter screen 10 are fixedly connected with an annular plate 3. Baijiu is transported to the inside of the first annular filter screen 9 through the feeding pipe 2. Since the discharge holes 4 inside the annular plate 3 are blocked, the baijiu flows to the partition plate 5 through the first annular filter screen 9, the filtering materials 11 and the second annular filter screen 10, and finally flows out through the drain pipe 6, achieving the purpose of filtering the baijiu.

[0028] As Figure 2 and Figure 5 shown, the extrusion mechanism 8 includes: A rotating shaft 12 is arranged inside the annular plate 3. The top of the rotating shaft 12 penetrates through the filtering box 1 and extends to a motor 13. The motor 13 is fixedly connected with the filtering box 1. The rotating shaft 12 is fixedly connected with the motor 13. An auger blade 14 is fixedly connected with an outer surface of the rotating shaft 12 at a position inside the first annular filter screen 9. The auger blade 14 is adapted to the first annular filter screen 9. An extrusion plate 15 is arranged at the bottom of the annular plate 3. A limiting plate 16 is fixedly connected with the bottom of the extrusion plate 15. Both the extrusion plate 15 and the limiting plate 16 are sleeved on the outer surface of the rotating shaft 12. An elastic mechanism 17 for pressing the extrusion plate 15 is arranged at the bottom of the rotating shaft 12. The motor 13 is started. The output end of the motor 13 drives the rotating shaft 12 to rotate. While the rotating shaft 12 rotates, it drives the auger blade 14. The auger blade 14 rotates to transport the separated impurities to the annular plate 3, so that the impurities accumulate inside the discharge holes 4. When the impurities accumulate to a certain extent, the auger blade 14 applies a downward pressure to the impurities. The elastic mechanism 17 drives the extrusion plate 15 through the limiting plate 16, so that the extrusion plate 15 applies an upward thrust to the impurities, thereby extruding the impurities. The extruded baijiu flows to the partition plate 5 through the first annular filter screen 9, the filtering materials 11 and the second annular filter screen 10. The user can separate the baijiu from the impurities in the baijiu and extrude the separated impurities, thereby improving the separation effect of the baijiu and the impurities in the baijiu, and solving the problem that although the existing filtering device for baijiu brewing is convenient for replacing and cleaning diatomaceous earth and can filter and separate the baijiu and the impurities inside the baijiu, the impurities inside the baijiu have a large water absorption capacity, resulting in a small amount of baijiu still remaining in the separated impurities, making the separation effect of the baijiu and the impurities poor.

[0029] As Figure 4 and Figure 5As shown in the figure, the elastic mechanism 17 includes: a screw rod 18 is fixedly connected to the bottom end of the rotating shaft 12. The outer surface of the bottom end of the screw rod 18 is rotatably connected to a circular plate 19. Four corners of the circular plate 19 are fixedly connected with L-shaped connecting rods 20. One ends of the L-shaped connecting rods 20 far from the circular plate 19 are fixedly connected to the annular plate 3. A threaded sleeve 21 is threadedly connected to the outer surface of the screw rod 18. A strong spring 22 is arranged between the threaded sleeve 21 and the limiting plate 16. The strong spring 22 is sleeved on the outer surface of the screw rod 18. The strong spring 22 pushes the limiting plate 16 through the cooperation of the threaded sleeve 21. The limiting plate 16 drives the extrusion plate 15, and then applies a certain thrust to the extrusion plate 15. When too much impurities accumulate, the pressure exerted by the device on the impurities is greater than the elastic force of the strong spring 22 itself. The impurities squeeze the extrusion plate 15 downward. The extrusion plate 15 drives the limiting plate 16, so that the extrusion plate 15 and the limiting plate 16 slide downward on the surface of the rotating shaft 12. As a result, a gap is generated between the extrusion plate 15 and the annular plate 3. The squeezed impurities are discharged to the bottom of the filter box 1 through the gap between the extrusion plate 15 and the annular plate 3.

[0030] As Figure 1 shown, a box door 23 is arranged near the threaded sleeve 21 of the filter box 1. One side of the box door 23 is fixedly connected to the filter box 1 through two hinges 24. A handle 25 is fixedly connected to the side of the box door 23 far from the hinge 24. The user can open the box door 23 through the cooperation of the handle 25 and the hinge 24, and then rotate the threaded sleeve 21. The threaded sleeve 21 rotates and lifts on the surface of the screw rod 18, so as to adjust the distance between the threaded sleeve 21 and the limiting plate 16, and achieve the purpose of adjusting the softness and hardness of the strong spring 22. The user can adjust the extrusion force exerted by the device on the impurities according to the needs, and then adjust the separation of white liquor in the impurities, improving the practicability, solving the problem that the original filtering device for white liquor brewing cannot adjust the device according to the material and water absorption of the impurities, and thus improving the separation of white liquor in the impurities.

[0031] As Figure 1 and Figure 2 shown, a waste outlet 26 is opened at the bottom of the filter box 1. The inner wall of the filter box 1 near the waste outlet 26 is set as an inclined surface. Since the bottom of the filter box 1 is set as an inclined surface, the impurities discharged to the bottom of the filter box 1 will slide to the waste outlet 26 and finally be discharged through the waste outlet 26.

[0032] As Figure 1 and Figure 2 shown, a fixed ring 27 is fixedly connected to the outer surface of the filter box 1. Four corners of the bottom of the fixed ring 27 are fixedly connected with support rods 28. The bottoms of the support rods 28 are fixedly connected with support feet 29. Anti-slip pads 30 are fixedly connected to the bottoms of the support feet 29, improving the stability of the device placement and avoiding the displacement phenomenon of the device due to vibration during operation.

[0033] Working principle: The user uses the conveying device to transport the white liquor from the feed pipe 2 into the first annular filter screen 9 inside the filtration tank 1. Since the discharge holes 4 inside the annular plate 3 are blocked, the white liquor flows through the first annular filter screen 9, the filter material 11, and the second annular filter screen 10 to the partition plate 5, and finally flows out through the drain pipe 6, achieving the purpose of filtering the white liquor. Start the motor 13, the output end of the motor 13 drives the rotating shaft 12 to rotate. While the rotating shaft 12 rotates, it drives the auger blades 14. The rotating auger blades 14 transport the separated impurities to the annular plate 3, causing the impurities to accumulate inside the discharge holes 4. When the impurities accumulate to a certain extent, the auger blades 14 exert a downward pressure on the impurities. At the same time, the strong spring 22 pushes the limit plate 16 through the cooperation of the internal thread sleeve 21. The limit plate 16 drives the extrusion plate 15, thereby exerting a certain thrust on the extrusion plate 15, so that the auger blades 14 and the extrusion plate 15 squeeze the impurities to squeeze out the white liquor in the impurities. The squeezed white liquor flows through the first annular filter screen 9, the filter material 11, and the second annular filter screen 10 to the partition plate 5. And when there is too much accumulation of impurities, the pressure exerted by the device on the impurities is greater than the elastic force of the strong spring 22 itself. The impurities squeeze the extrusion plate 15 downward, and the extrusion plate 15 drives the limit plate 16, causing the extrusion plate 15 and the limit plate 16 to slide downward on the surface of the rotating shaft 12, thereby creating a gap between the extrusion plate 15 and the annular plate 3. The squeezed impurities are discharged to the bottom of the filtration tank 1 through the gap between the extrusion plate 15 and the annular plate 3, and then discharged through the waste outlet 26. The user can separate the white liquor from the impurities in the white liquor and squeeze the separated impurities, thereby improving the separation effect of the white liquor and the impurities in the white liquor, and solving the problem that the existing filtration device for white liquor brewing is convenient for replacing and cleaning diatomaceous earth and can filter and separate the white liquor and the impurities inside the white liquor. However, the impurities inside the white liquor have a large water absorption capacity, resulting in a small amount of white liquor still remaining in the separated impurities, making the separation effect of the white liquor and the impurities poor.

[0034] The user can open the box door 23 through the cooperation of the handle 25 and the hinge 24, and then rotate the internal thread sleeve 21. While the internal thread sleeve 21 rotates on the surface of the screw rod 18, it rises and falls, thereby achieving the purpose of adjusting the distance between the internal thread sleeve 21 and the limit plate 16, and achieving the purpose of adjusting the softness and hardness of the strong spring 22. The user can adjust the extrusion force exerted by the device on the impurities according to the needs, thereby adjusting the separation of the white liquor in the impurities, improving the practicability, and solving the problem that the original filtration device for white liquor brewing cannot adjust the device according to the material and water absorption of the impurities, thereby improving the separation of the white liquor in the impurities.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
