Description

Technical Field

[0001] The present invention relates to the technical field of filtration in liquor production, and in particular to a filtration device for producing fragrant and soft liquor. Background Art

[0002] In the liquor industry, rich and soft-flavored liquor is popular among consumers for its unique taste and flavor. However, during the production process, in order to ensure the purity of the liquor and preserve its flavor, the liquor needs to be filtered.

[0003] A search revealed Chinese patent application number CN117919815A, which discloses a filtration device for liquor production. The device comprises a base, a water pump, a connecting pipe assembly, and a filter. The filter comprises a housing on which are mounted a drive assembly, a cleaning assembly, and a vibration assembly. This invention utilizes a cleaning assembly to drive a spiral scraper, which scrapes away adherent impurities from the filter element's surface and pushes them above the liquor level. Simultaneously, the vibration assembly drives the filter element to vibrate up and down, removing non-adhesive impurities from the filter element's surface due to vibration and collision with the scraper. However, this solution still suffers from the following deficiencies in actual use:

[0004] During the baijiu production process, impurity levels vary significantly between batches. This characteristic necessitates timely enhancement of filtration efficiency to ensure product quality. However, in practice, current filtration equipment often requires multiple repetitive filtration cycles to achieve the desired purification effect. This process not only increases operational complexity but also significantly reduces overall production efficiency, becoming a key factor restricting the smoothness and cost-effectiveness of the production process.

[0028] Beneficial effects of the present invention:

[0029] 1. This cantilever automatic pipe arrangement device enables flexible adjustment of multi-stage filtration:

[0030] By setting up a liftable adjustment tube in conjunction with a multi-level filtration chamber, the connection between the water outlet and different filtration levels is controlled by adjusting the height of the tube, thereby realizing dynamic switching of the number of filtration devices (such as single-layer, double-layer or triple-layer filtration); the filtration density can be flexibly adjusted according to the impurity content of the liquor, while ensuring the basic filtration efficiency, significantly improving the filtration effect on high-impurity liquor, avoiding the problem of traditional devices requiring repeated filtration or equipment replacement.

[0031] 2. This cantilever automatic pipe arrangement device realizes pressure adaptive compensation mechanism

[0032] Through the linkage design of the pressure regulating component (rotating disk + conical pressure tube) and the control component, the rotating disk rotates synchronously with the rise and fall of the regulating tube, so that the diameter of the pressure tube matches the current filtration level (for example, the smallest diameter pressure tube is selected for three-layer filtration); it automatically compensates the water pressure for different filtration densities to solve the problem of decreased flow rate caused by multi-layer filtration, which not only ensures the driving force of high-density filtration, but also avoids energy waste during low-level filtration, thereby achieving energy efficiency optimization.

[0033] 3. This cantilevered automatic pipe arrangement device optimizes the staggered outlet pipe layout:

[0034] By arranging circular arrays of staggered outlet pipes in the first, second and third filter chambers, with drainage holes evenly arranged and staggered at the connection points with the fixed pipes, the liquor forms a multi-directional impact flow in the chamber and fully contacts the filter mesh; the staggered layout avoids interference between the upper and lower water flows, improves filtration uniformity and single filtration efficiency, and reduces residual impurities.

[0053] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0054] It should be noted that, unless otherwise defined, the technical or scientific terms used in the present invention should have the usual meanings understood by people with ordinary skills in the field to which the present invention belongs. The "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0055] like Figures 1 to 2 As shown, a filtering device for producing fragrant and soft liquor includes a filter barrel 1 and a first water inlet pipe 8. A second water inlet pipe 10 is provided on the filter barrel 1. A pressure regulating assembly 9 is provided at the bottom of the first water inlet pipe 8. The first water inlet pipe 8 is connected to the second water inlet pipe 10 through the pressure regulating assembly 9. A drain pipe 19 is connected to the bottom of the filter barrel 1.

[0056] Secondly, the filter barrel 1 is provided with a first filter device 2, a second filter device 3 and a third filter device 4 from top to bottom, which are used to divide the filter barrel 1 into a first filter chamber 5, a second filter chamber 6 and a third filter chamber 7. A fixed pipe 11 is fixed at the center of the filter barrel 1. Figure 3As shown, the fixed pipe 11 is provided with a plurality of water outlet pipes 12 in a circular array around the center of the first filter chamber 5, the second filter chamber 6 and the third filter chamber 7. A plurality of drainage holes are evenly opened at the bottom of the water outlet pipe 12. This is convenient for ensuring that the liquor enters the corresponding chamber when the filter chamber needs to be replaced, so that the liquor can be more efficiently impacted with the filter screen for filtration, thereby improving the filtration effect and filtration efficiency. The staggered arrangement can prevent the lower water outlet pipe 12 from affecting the discharge of the upper water outlet pipe 12.

[0057] It is worth mentioning that the plurality of water outlet pipes 12 located in the first filter chamber 5, the second filter chamber 6 and the third filter chamber 7 are arranged in a staggered manner, and the length of the water outlet pipe 12 is adapted to the inner radius of the filter barrel 1;

[0058] Further, refer to Figure 4-Figure 6 As shown, the fixed pipe 11 is slidably connected with an adjusting pipe 13, and the bottom of the adjusting pipe 13 is provided with a water outlet 15 for separately communicating with the first filter chamber 5, the second filter chamber 6 and the third filter chamber 7. The water outlets 15 are arranged in a circular array, and at least one water outlet 15 is located at the connection point between the water outlet pipe 12 and the fixed pipe 11, so that the water outlet 15 can be moved to the corresponding filter chamber to communicate with the corresponding water outlet pipes 12 in the chamber; and the adjusting pipe 13 is provided with a first slot 16, a second slot 17 and a third slot 18 which are connected to the second water inlet pipe 10 when the water outlet 15 is connected to the first filter chamber 5, the second filter chamber 6 and the third filter chamber 7 respectively. A water inlet 14 is provided on the fixed pipe 11 at the connection point of the second water inlet pipe 10, and the second water inlet pipe 10 is connected to the first slot 16, the second slot 17 and the third slot 18 respectively through the water inlet 14.

[0059] It should be added that the distances between the outlet pipes 12 in the first filter chamber 5 and the second filter chamber 6 and between the second filter chamber 6 and the third filter chamber 7 are the same; secondly, the lengths of the first slot 16, the second slot 17 and the third slot 18 are greater than the length of the water inlet 14, and the length of the first slot 16 is less than the distance between the connection points of the several outlet pipes 12 in the second filter chamber 6 and the fixed pipe 11 and the connection points of the several outlet pipes 12 in the third filter chamber 7 and the fixed pipe 11, and the length of the second slot 17 is less than the distance between the connection points of the several outlet pipes 12 in the first filter chamber 5 and the fixed pipe 11 and the connection points of the several outlet pipes 12 in the second filter chamber 6 and the fixed pipe 11; and when the water outlet 15 is connected to the water outlet pipe 12 in the third filter chamber 7 and the fixed pipe 11, the bottom of the third slot 18 is located above the connection point of the water outlet pipe 12 in the first filter chamber 5 and the fixed pipe 11; and the top of the adjusting pipe 13 is sealed.

[0060] When the device is in use, Figure 7-Figure 9 As shown in the working state diagram, when the impurity content of the product is not much, simple filtration is required and the filtration efficiency needs to be improved, the outlet 15 of the regulating pipe 13 is moved to the place where it is connected to the outlet pipe 12 in the third filter chamber 7, as shown in FIG. Figure 7 It can be seen that at this time, the first water inlet pipe 8 enters the second water inlet pipe 10 after passing through the pressure regulating assembly 9, and then flows into the fixed pipe 11, and enters the regulating pipe 13 through the overlap with the water inlet 14 and the third notch 18, and then enters the water outlet pipe 12 in the third filter chamber 7 through the water outlet 15, and then is discharged into the third filter chamber 7 for filtration. Then, the two filter devices above, namely the first filter device 2 and the second filter device 3, will not participate in the work, and only the third filter device 4 in the lower part of the third filter chamber 7 will participate in the work, so the filtering effect will be reduced. Similarly, due to the reduction of the number of filter devices, the filtering density will be reduced, and the filtering efficiency will be improved;

[0061] When the impurity content of the product is high and the filtration effect needs to be improved, the regulating tube 13 can be raised to Figure 8 In the second filter chamber 6, the water outlet 15 is overlapped with the connection point of the water outlet pipe 12 in the second filter chamber 6. At this time, the second notch 17 of the regulating pipe 13 is overlapped with the water inlet 14. In this way, the first notch 16 and the third notch 18 will not participate in the work, thereby ensuring that the filter chamber above the filter chamber where the water outlet 15 is located does not participate in the work. Figure 8 It can be seen that at this time, the second filtering device 3 and the third filtering device 4 will participate in the work together, increasing the filtering density and thus improving the filtering effect.

[0062] Furthermore, Figure 11 and Figure 12As shown, the pressure regulating assembly 9 includes a mounting pipe 91, which is fixed on the filter barrel 1. The bottom of the mounting pipe 91 is connected to a gathering pipe 92 with a cylindrical structure. A rotating disk 93 is rotated and sealed in the mounting pipe 91. The rotating disk 93 is provided with a flow port 94. A first pressure pipe 95, a second pressure pipe 96 and a third pressure pipe 97 are respectively arranged in a circular array close to the bottom of the rotating disk 93 in the mounting pipe 91. A support frame 98 is fixed in the mounting pipe 91 below the rotating disk 93. The first pressure pipe 95, the second pressure pipe 96 and the third pressure pipe 97 are fixedly connected to the mounting pipe 91 through the support frame 98; then the first water inlet pipe 8 is connected to the mounting pipe 91 above the rotating disk 93. It is noted that the first pressure tube 95, the second pressure tube 96 and the third pressure tube 97 are all conical structures, and the top inner diameters of the first pressure tube 95, the second pressure tube 96 and the third pressure tube 97 are the same, the inner diameter of the flow port 94 is adapted to the top inner diameters of the first pressure tube 95, the second pressure tube 96 and the third pressure tube 97, and the top inner diameters and bottom inner diameters of the first pressure tube 95, the second pressure tube 96 and the third pressure tube 97 become larger in sequence; the first pressure tube 95, the second pressure tube 96 and the third pressure tube 97 here are all set to pass through from top to bottom; and there are gaps at the connection between the first pressure tube 95, the second pressure tube 96 and the third pressure tube 97 and the mounting tube 91 through the support frame 98.

[0063] When the device is in use, when the rotating disk 93 coincides with the first pressurized pipe 95, the first water inlet pipe 8 is connected to the first pressurized pipe 95, and then enters the gathering pipe 92, and finally enters the fixed pipe 11 through the second water inlet pipe 10. The bottom end of the first pressurized pipe 95 is thinner, so the water pressure is greater. Correspondingly, when the water outlet 15 mentioned above coincides with the water outlet pipe 12 in the first filter chamber 5, there are three filtering devices below, namely the first filter device 2, the second filter device 3 and the third filter device 4, so the filtering effect is improved, the filtering density is increased, and the filtering efficiency will be reduced, so a greater water pressure is required to drive it, so through The first pressure pipe 95 obtains the maximum water pressure to compensate, and the three filtering devices involved in the present invention, the first filtering device 2, the second filtering device 3 and the third filtering device 4, and the corresponding first notch 16, second notch 17 and third notch 18 on the regulating pipe 13 and the first pressure pipe 95, the second pressure pipe 96 and the third pressure pipe 97 are only used as examples for reference. During specific implementation, three or more pressure pipes can be set as needed; and the structure of the gathering pipe 92 is set in order to further increase the water pressure and to adapt it to the structure of the first pressure pipe 95, the second pressure pipe 96 and the third pressure pipe 97, so that it can receive the water flow more smoothly.

[0064] Specifically, such as Figure 1 and Figure 10As shown, the filter barrel 1 is provided with a lifting assembly 20 for driving the regulating tube 13 to rise and fall. The lifting assembly 20 includes a mounting frame 201 fixedly mounted on the filter barrel 1. A servo motor 202 is fixedly mounted on the top of the mounting frame 201. A threaded screw 203 is fixedly mounted on the output end of the servo motor 202. A movable plate 204 is threadedly connected to the threaded screw 203. The movable plate 204 is fixedly connected to the top of the regulating tube 13. Limit rods 205 are fixedly mounted on both sides of the threaded screw 203 on the mounting frame 201. The movable plates 204 are slidably connected to each other.

[0065] When the device is in use, the servo motor 202 is started to rotate the threaded screw 203, and under the limiting action of the limit rod 205, the movable plate 204 moves up and down. The servo motor 202 is used because the motor can more accurately drive the movable plate 204 to the specified position and then stop, and then drive the adjustment tube 13 to the specified position through the movable plate 204.

[0066] Further, such as Figure 1 and Figure 10 As shown, a control assembly 21 for controlling the rotation of the rotating disk 93 is provided near the movable plate 204; wherein the control assembly 21 includes a rack 211 fixedly mounted on the movable plate 204, a rotating rod 213 is rotatably provided near the mounting tube 91, one end of the rotating rod 213 near the rack 211 is fixedly connected to a gear 212, the gear 212 is meshed with the rack 211, and the end of the rack 211 away from the gear 212 is fixedly connected to a driving bevel gear 214, a connecting rod 216 is fixedly provided at the center of the rotating disk 93, the connecting rod 216 is rotatably connected to the top of the mounting tube 91, the end of the connecting rod 216 away from the rotating disk 93 extends to the outside of the mounting tube 91 and is fixedly connected to a driven bevel gear 215, and the driven bevel gear 215 is meshed with the driving bevel gear 214;

[0067] It is worth mentioning that when the movable plate 204 rises or falls the distance between the water outlet pipe 12 between the second filter chamber 6 and the third filter chamber 7, the rotating disk 93 rotates 120 degrees clockwise; in this way, when the device is in use, when the movable plate 204 rises or falls into a certain filter chamber and connects the water outlet 15 with the water outlet pipe 12 therein, the rotating disk 93 will be connected with the corresponding pressurized pipe, that is, when the water outlet 15 is connected with the water outlet pipe 12 in the first filter chamber 5, the first water inlet pipe 8 is connected with the first pressurized pipe 95 through the rotating disk 93 to obtain a greater water pressure, and so on; and the figure is only for illustration, the specific text shall prevail.

[0068] In summary, by moving the regulating tube 13 to change the number of filtering devices and thus changing the filtering effect, and cooperating with the pressure regulating component 9 to compensate for the water pressure, the problem of repeated filtration and reduced filtering efficiency due to different filtering requirements can be effectively solved.

[0069] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention is limited to these examples. Within the scope of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
