Description

Technical Field

[0001] This utility model relates to the field of cross-flow wine filtration, specifically to a cross-flow wine filtration machine. Background Technology

[0002] The cross-flow wine filter is an advanced piece of equipment used in the wine production process for solid-liquid separation, sterilization, and clarification. It represents the forefront of wine filtration technology today. Compared with traditional filtration methods, such as diatomaceous earth filtration and plate and frame filtration, it adopts an innovative cross-flow filtration principle, which greatly improves the filtration quality and production efficiency of wine.

[0003] In the industrial production of wine, cross-flow filtration is a crucial process for removing impurities such as fruit pulp residue, yeast cells, and colloidal substances from the wine, directly affecting the clarity, stability, and taste of the wine. Traditional wine filtration equipment mostly adopts static filtration methods. After prolonged use, the filter frame and filter element are easily clogged by impurities, resulting in a significant decrease in filtration efficiency. Moreover, in terms of equipment maintenance, the cleaning process of existing filtration equipment is cumbersome. Manual disassembly and cleaning of filter components not only consumes a lot of manpower and time costs, but frequent disassembly also accelerates component wear and shortens the service life of the equipment. In view of this, we propose a cross-flow wine filtration machine. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned shortcomings and provide a wine cross-flow filter machine, which solves the problems in the industrial production of wine, where traditional static filtration equipment is prone to clogging by impurities, resulting in reduced efficiency, complicated cleaning process, labor-intensive and time-consuming manual maintenance, and accelerated wear of parts.

[0005] To achieve the above objectives, this utility model provides a wine cross-flow filter, including a filter cylinder, a filter frame inside the filter cylinder, a cross-flow filter core fixedly installed inside the filter frame, and a cleaning mechanism on one side inside the filter cylinder.

[0006] The cleaning mechanism includes a first gear rotatably connected to the filter cylinder, a second gear meshing with the outer edge of the first gear, a cleaning brush rotatably connected to the bottom of the second gear, and the bottom surface of the second gear connected to the outer wall of the top of the filter frame.

[0007] The beneficial effects of this utility model are:

[0008] 1. In this utility model, the filter frame inside the filter cylinder is equipped with a cross-flow filter core, which can effectively filter impurities in wine; the second gear in the cleaning mechanism drives the filter frame and the cross-flow filter core to rotate synchronously, so that the cleaning brush can remove the blockages on the surface of the filter frame and the filter core in time, avoid the accumulation of impurities affecting the filtration efficiency, ensure the wine is continuously and smoothly filtered, and improve the purity of the product.

[0009] Furthermore, the flushing system, consisting of water injection pipes, diversion columns, and nozzles, can flush the filter frame and filter element with water flow when they rotate, thoroughly cleaning the fine particles and sticky substances in the filter channels and gaps. Combined with the cleaning brush, it achieves dual cleaning of "mechanical friction + fluid flushing", improving cleanliness and reducing the risk of secondary pollution.

[0010] As a further improvement to this technical solution, a feeding pipe is connected through the top of the filter cylinder, and the bottom end of the feeding pipe passes through the top of the filter cylinder and is connected to the filter frame. A discharge pipe is connected through the bottom of the filter cylinder, and the bottom of the filter cylinder is inverted triangular in shape. A guide pipe is connected through one side of the filter cylinder. A support frame is fixedly connected to the outer ring of the bottom of the filter cylinder to support the stability of the filter cylinder. A drive motor is fixedly installed on the top of the filter cylinder, and the output end of the drive motor is fixedly connected to the inner wall of the first gear.

[0011] The beneficial effects of adopting the above-mentioned further solution are that the feeding pipe passes through the top of the filter cylinder and is connected to the filter frame, realizing the precise delivery of wine and ensuring that the wine can directly enter the cross-flow filter core in the filter frame, avoiding spillage and contamination; the discharge pipe is connected to the bottom of the inverted triangular filter cylinder, and the filtered wine is discharged more smoothly by using gravity, preventing residue and improving discharge efficiency.

[0012] As a further improvement to this technical solution, a connecting plate is fixedly connected to one side of the cleaning brush, and one side of the connecting plate is connected to the inner wall of the filter cylinder. The side of the cleaning brush that fits against the filter frame is arc-shaped and adapted to the filter frame.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the arc-shaped design of the cleaning brush fitting the filter frame can closely fit the outer contour of the filter frame, ensuring that the bristles can fully cover its surface during the rotation of the filter frame, reducing cleaning dead corners.

[0014] As a further improvement to this technical solution, a water injection pipe is connected to the other end of the filter cylinder, and a diversion column is connected to one end of the water injection pipe. Spray nozzles are connected in a linear array on the diversion column, and the side of the diversion column opposite to the filter cylinder is fixedly connected to the inner wall of the filter cylinder.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, during or after the filtration process, clean water or cleaning solution (such as alkaline detergent) can be directly injected through the water injection pipe, and the nozzles will start rinsing simultaneously under the action of the diversion column, without the need to stop the machine and disassemble the filter components.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The present invention provides the following preferred embodiments.

[0028] Please see Figures 1-4 As shown, this embodiment provides a wine cross-flow filter, including a filter cylinder 100, a filter frame 200 is provided inside the filter cylinder 100, a cross-flow filter core 211 is fixedly installed inside the filter frame 200, and a cleaning mechanism 300 is provided on one side inside the filter cylinder 100.

[0029] The cleaning mechanism 300 includes a first gear 310 rotatably connected to the filter cylinder 100, a second gear 311 meshing with the outer edge of the first gear 310, a cleaning brush 312 rotatably connected to the bottom of the second gear 311, and the bottom surface of the second gear 311 connected to the outer wall of the top of the filter frame 200.

[0030] The improvement in this embodiment is as follows:

[0031] Considering that cross-flow filters are prone to clogging of the filter components over time, thereby reducing the filtration effect and resulting in insufficient purity of the filtered wine, affecting its taste, the wine is first filtered through the cross-flow filter core 211 in the filter frame 200. Then, the rotation of the first gear 310 drives the second gear 311, which in turn drives the filter frame 200 and its internal cross-flow filter core 211 to rotate synchronously. During the rotation, the filter frame 200 and the cross-flow filter core 211 come into contact with the cleaning brush 312, allowing the cleaning brush 312 to clean both of them simultaneously. The cleaning brush 312 can promptly remove impurities, filter residue, and other blockages attached to the surfaces of both, which avoids clogging of the filter channel caused by the accumulation of impurities. This ensures that the wine continues to pass smoothly through the filter core, significantly improving the filtration efficiency. At the same time, reducing the residue of impurities also makes the filtered wine purer, effectively improving product quality.

[0032] Furthermore, impurities accumulating on the surface of the filter frame 200 and the cross-flow filter element 211 may damage the components due to pressure, corrosion, etc. Timely cleaning by the cleaning brush 312 can reduce the erosion and wear of impurities on the filter components, reduce the wear and tear on the filter frame 200 and the cross-flow filter element 211, extend their service life, and thus reduce the overall maintenance and replacement costs of the equipment.

[0033] Based on the above, the specific structure will be disclosed in detail:

[0034] Considering the need for smooth wine introduction and proper drainage of the cleaning liquid inside the filter cartridge 100, the structure of the filter cartridge 100 is disclosed in detail, such as... Figure 2 As shown, the top of the filter cylinder 100 is connected to the feeding pipe 101, and the bottom end of the feeding pipe 101 passes through the top of the filter cylinder 100 and is connected to the filter frame 200. The bottom of the filter cylinder 100 is connected to the discharge pipe 102, and the bottom of the filter cylinder 100 is inverted triangular. Therefore, when wine needs to be added for cross-flow filtration, the wine is transported through the feeding pipe 101 to the inside of the cross-flow filter core 211 on the conveying frame by an external pump for filtration. The filtered wine is then transported to the inside of the external storage device through the discharge pipe 102.

[0035] Specifically, a guide pipe is connected through one side of the filter cylinder 100, and a support frame is fixedly connected to the outer ring of the bottom of the filter cylinder 100 to support the stability of the filter cylinder 100. Through the guide pipe, cleaning liquid can be added into the filter cylinder 100 to ensure that the filtered red wine will not remain on the inner wall of the bottom of the filter cylinder 100.

[0036] A drive motor 103 is fixedly installed on the top of the filter cartridge 100. The output end of the drive motor 103 is fixedly connected to the inner wall of the first gear 310. By rotating the drive motor 103, the first gear 310, the second gear 311 and the cleaning brush 312 are driven to rotate, so as to clean the impurities remaining on the filter frame 200 and the cross-flow filter element 211.

[0037] Furthermore, to achieve the cleaning of the filter frame 200 and the cross-flow filter element 211, a cleaning mechanism 300 is further disclosed, such as... Figure 3 and Figure 4 As shown, a connecting plate is fixedly connected to one side of the cleaning brush 312. One side of the connecting plate is connected to the inner wall of the filter cylinder 100. The side of the cleaning brush 312 that fits against the filter frame 200 is arc-shaped and adapted to the filter frame 200. When it is necessary to clean the filter frame 200 and the cross-flow filter element 211, the drive motor 103 is started. Its operation drives the first gear 310 to rotate. The first gear 310 further drives the filter frame 200 to rotate. During the rotation, the filter frame 200 comes into contact with the cleaning brush 312, thereby realizing the rolling cleaning of the filter frame 200 by the cleaning brush 312. The rolling cleaning method allows the cleaning brush 312 to fully contact the surface of the filter frame 200, which can effectively remove attached impurities and dirt, avoid clogging, ensure the filtration effect, and timely cleaning can prevent the accumulation of impurities from affecting the rotation of the filter frame 200, reduce the risk of equipment failure, and ensure the continuous and stable operation of wine filtration.

[0038] However, to achieve further cleaning effects from the filter frame 200 and the cross-flow filter element 211, the internal structure of the filter cartridge 100 is disclosed in detail, such as... Figure 4As shown, a water injection pipe 400 is connected to the other end of the filter cylinder 100, and a diversion column 510 is connected to one end of the water injection pipe 400. Spray nozzles 511 are linearly arrayed on the diversion column 510. The side of the diversion column 510 opposite to the filter cylinder 100 is fixedly connected to the inner wall of the filter cylinder 100. Therefore, by connecting an external water supply device, such as a water pump, through the water injection pipe 400, water is delivered to the diversion column 510, and then the diversion column 510 delivers the water to each spray nozzle 511. The spray nozzles 511 then spray water onto the filter frame 200 and the cross-flow filter element 211. Simultaneously, the filter frame 200 and the cross-flow filter element 200 are rotating, and the cleaning brush 312 completes the cleaning process. The initial cleaning of the filter frame 200 and the cross-flow filter element 211 is achieved by the water sprayed from the nozzle 511, which can further clean the filter frame 200 and the cross-flow filter element 211. When the filter frame 200 and the cross-flow filter element 211 rotate, the cleaning brush 312 removes impurities such as grape skins and pulp fibers through physical contact, completing the initial mechanical cleaning. The water flow sprayed from the nozzle 511, such as high-pressure water or cleaning fluid, can penetrate deep into the filter channels and component gaps to wash away residual fine particles and sticky substances such as pectin and microbial residues, achieving a dual cleaning mode of "mechanical friction + fluid flushing". Compared with a single cleaning method, the cleanliness is improved by more than 90%, ensuring that the filter components are thoroughly cleaned and reducing the risk of secondary pollution.

[0039] In practical use, the wine to be filtered is injected into the filter cylinder 100 through the feeding pipe 101. The wine enters the filter frame 200 through the feeding pipe 101 and is filtered under the action of the cross-flow filter core 211. The filtered wine is discharged through the discharge pipe 102.

[0040] Start the drive motor 103, which drives the first gear 310 to rotate. The first gear 310 drives the second gear 311 to rotate through meshing, so that the filter frame 200 and the cross-flow filter element 211 also rotate synchronously. During the rotation, the cleaning brush 312 contacts the filter frame 200 and the cross-flow filter element 211 to perform preliminary cleaning of the impurities on their surfaces.

[0041] When further cleaning is required, water is injected into the filter cartridge 100 through the water injection pipe 400. The water flows through the diversion column 510 and sprays out in a linear array from the nozzle 511, flushing the rotating filter frame 200 and the cross-flow filter element 211 to achieve a more thorough cleaning. Wastewater generated during the cleaning process can be discharged from the filter cartridge 100 through the outlet at the bottom of the filter cartridge 100, completing the entire filtration and cleaning process.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
