Description

Technical Field

[0001] This utility model relates to the field of filtration technology, specifically a filtration device for vinegar production. Background Technology

[0002] In the vinegar brewing industry, filtration is a key process that determines the quality of the finished vinegar. Its core function is to remove residual fruit pulp, fermentation residue, yeast, and colloidal impurities from the fermentation process.

[0003] Existing devices mostly use a single filter layer combined with a fixed cavity structure. The single filter layer structure creates a contradiction in the selection of filter layer pore size. If the pore size is too large, it can reduce clogging, but it cannot intercept tiny impurities such as yeast. If the pore size is too small, although it can improve the filtration accuracy, it is easily clogged by large particles of residue. Secondly, existing filter layers are mostly horizontally fixed, and impurities tend to accumulate on the surface of the filter layer due to gravity. After filtering for a period of time, manual removal of impurities is required.

[0004] Therefore, a filtration device for vinegar production is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a filtration device for vinegar production, which can solve the problems of difficulty in selecting filter holes and the need for manual impurity removal.

A feed pipe is fixedly installed at the upper end of each filter barrel, and a main feed pipe is fixedly connected to the upper end of the feed pipe. A coarse filter barrel is fixedly installed inside each filter barrel, forming a cavity with its inner wall. This cavity is configured as a diversion and discharge chamber. A fine filter barrel is fixedly installed inside the coarse filter barrel, forming a cavity with its inner wall. This cavity is configured as a recovery chamber. An arc-shaped coarse filter plate is fixedly installed on the outer side of the coarse filter barrel. A return pipe is fixedly installed on the inner wall of the coarse filter barrel. A discharge pipe is fixedly installed at the bottom of the fine filter barrel. A recovery pipe is fixedly installed at the bottom of the recovery chamber. A discharge pipe is fixedly installed on the outer side of the filter barrel.

Detailed Implementation

[0017] 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. Example

[0018] Please see Figure 1 - Figure 4 This embodiment of a filtration device for vinegar production includes a support frame 1. Several filter barrels 2 are fixedly arranged inside the support frame 1. The filter barrels 2 are linearly distributed. A feed pipe 5 is fixedly arranged at the upper end of the filter barrel 2. A feed main pipe 6 is fixedly connected to the upper end of the feed pipe 5. A coarse filter barrel 3 is fixedly arranged inside the filter barrel 2. The coarse filter barrel 3 and the inner wall of the filter barrel 2 form a cavity. The cavity is configured as a diversion and sewage discharge chamber 4. A fine filter barrel 7 is fixedly arranged inside the coarse filter barrel 3. The fine filter barrel 7 and the inner wall of the coarse filter barrel 3 form a cavity. The cavity is configured as a recovery chamber 13. An arc-shaped coarse filter plate 9 is fixedly arranged on the outside of the coarse filter barrel 3. A return pipe 10 is fixedly arranged on the inner wall of the coarse filter barrel 3. A discharge pipe 12 is fixedly arranged at the bottom of the fine filter barrel 7. A recovery pipe 14 is fixedly arranged at the bottom of the recovery chamber 13. A sewage discharge pipe 11 is fixedly arranged on the outside of the filter barrel 2. When preparing to filter vinegar, the fermented vinegar is pumped by a centrifugal pump and transported through pipelines into the feed main pipe 6. The vinegar in the feed main pipe 6 is then distributed into various feed pipes 5 connected to it. After entering the filter tank 2, the vinegar first flows to the upper surface of the coarse filter tank 3, where it undergoes preliminary filtration. The filtered vinegar flows into the interior of the coarse filter tank 3. Impurities and a small portion of unfiltered vinegar due to impact impurities flow into the diversion and discharge chamber 4. The vinegar entering the coarse filter tank 3 flows to the upper end of the fine filter tank 7 for fine filtration. The filtered vinegar flows into the fine filter tank 7 and is discharged through the discharge pipe 12. Tiny impurity particles and a small portion of unfiltered vinegar due to impact impurities at the upper end of the fine filter tank 7 flow into the recovery chamber 13. The vinegar is discharged through the recovery pipe 14 for recycling. As the amount of unfiltered vinegar and larger particulate impurities in the diversion and drainage chamber 4 increases, the vinegar in the diversion and drainage chamber 4 flows into the inner side of the arc-shaped coarse filter plate 9 and flows through the return pipe 10 to the upper end of the fine filter tank 7 for fine filtration. The large particulate impurities in the diversion and drainage chamber 4 are discharged through the drainage pipe 11. The vinegar feed adopts a pipeline automatic transportation system, which does not require manual handling. The filtered vinegar is connected to the finished product storage tank through a pipeline. The vinegar in the recovery chamber 13 is connected back to the centrifugal pump inlet through a pipeline to achieve recycling and re-filtration. The use of the pipeline automatic transportation system and the centrifugal pump are common technologies in the existing vinegar filtration industry, so the specific structural composition and working principle will not be described in detail in this embodiment.

[0019] The coarse filter barrel 3 is designed as a crescent-shaped hollow column structure. The upper end of the coarse filter barrel 3 is inclined, and several coarse filter holes are opened through the upper end of the coarse filter barrel 3. When the vinegar flows to the top of the coarse filter 3, the coarse filter holes intercept large particles of impurities. The tilt angle of the coarse filter 3 uses gravity and the force of the vinegar to guide the impurities into the diversion and discharge chamber 4, reducing the accumulation of impurities at the top of the coarse filter 3. The crescent-shaped hollow column structure of the coarse filter 3 forms a diversion and discharge chamber 4 with the inner wall of the filter 2. This structure has curved surface guidance and better spatial adaptability.

[0020] The feed pipe 5 connects the feed main pipe 6 and the internal space of the filter barrel 2. The feed pipe 5 is located above the coarse filter barrel 3 and is located at a higher position on the inclined surface of the coarse filter barrel 3. When vinegar enters the feed pipe 5 through the feed main pipe 6, the feed pipe 5 is located at a higher position on the inclined surface of the coarse filter barrel 3, ensuring that the vinegar evenly covers the entire inclined filter surface, reducing the proportion of unfiltered vinegar directly flowing into the diversion and discharge chamber 4. The design of the inclined filter surface causes the impurities intercepted by the filter surface to slide downward under the action of gravity, which, combined with the impact force of the vinegar, prevents the accumulation of impurities.

[0021] The fine filter barrel 7 is designed as a crescent-shaped hollow cylinder structure. The upper end of the fine filter barrel 7 is inclined, and a fine filter screen 8 is fixedly installed on the upper end of the fine filter barrel 7. The crescent-shaped hollow column structure of the fine filter tank 7 forms a recovery chamber 13 with the inner wall of the coarse filter tank 3. This structure has curved flow guidance and better spatial adaptability. The fine filter screen 8 intercepts small particulate impurities such as yeast. The inclined surface design allows the impurities intercepted by the filter surface to slide downward under the action of gravity, and the force of vinegar guides the impurities into the recovery chamber 13. The fine filter screen 8 is made of materials with fine filtration properties, such as ceramic membranes.

[0022] The arc-shaped coarse filter plate 9 is set in the diversion and sewage discharge chamber 4. The arc-shaped coarse filter plate 9 is set as an arc-shaped plate structure, and several coarse filter holes are provided through the surface of the arc-shaped coarse filter plate 9. The arc-shaped coarse filter plate 9 intercepts large particles of impurities in the diversion and discharge chamber 4, filters the vinegar in the diversion and discharge chamber 4, and leaves the intercepted impurities on the outside of the arc-shaped coarse filter plate 9.

[0023] The return pipe 10 connects the interior of the coarse filter barrel 3 with the inner space of the arc-shaped coarse filter plate 9. The return pipe 10 is inclined and the outlet of the return pipe 10 is located above the fine filter screen 8. The vinegar entering the inner side of the arc-shaped coarse filter plate 9 flows to the fine filter screen 8 through the return pipe 10, so that the fluid evenly covers the surface of the fine filter screen 8, and works in synergy with the inclined fine filter screen 8 to achieve fine filtration.

[0024] The lower end of the discharge pipe 12 is fixedly connected to the discharge main pipe 15, and the discharge pipe 12 connects the discharge main pipe 15 with the internal space of the fine filter tank 7. The lower end of the recovery pipe 14 is fixedly connected to the recovery main pipe 16, and the recovery pipe 14 connects the recovery main pipe 16 with the internal space of the recovery chamber 13. The sewage pipe 11 connects the outside with the internal space of the diversion sewage chamber 4. The pure vinegar inside the fine filter tank 7 is discharged through the discharge pipe 15, the vinegar inside the recovery chamber 13 is recovered through the recovery pipe 16, and the impurities in the diversion and sewage discharge chamber 4 are discharged through the sewage discharge pipe 11.

[0025] The working principle of the above embodiment is as follows: The fermented vinegar to be filtered is first distributed to the feed pipe 5 at the top of each filter tank 2 through the feed main pipe 6. Since the feed pipe 5 is located at a higher position on the inclined surface of the coarse filter tank 3, the vinegar can evenly cover the inclined filter surface at the top of the coarse filter tank 3. The vinegar undergoes preliminary filtration through the coarse filter holes on the coarse filter tank 3. Large particles of impurities are intercepted and flow into the diversion and discharge chamber 4 formed by the gravity of the inclined surface and the force of the vinegar under the action of the vinegar. The vinegar after preliminary filtration enters the interior of the coarse filter tank 3. Subsequently, the vinegar inside the coarse filter tank 3 flows to the top of the fine filter tank 7 inside it. Fine filtration is completed through the fine filter screen 8 set at the top of the fine filter tank 7. Small particles of impurities such as yeast are intercepted and flow into the recovery chamber 13 formed by the inclined surface of the coarse filter tank 3 and the fine filter tank 7. The pure vinegar after fine filtration enters the fine filter tank 7. Inside the filter barrel 7, the unfiltered vinegar and large particulate impurities accumulate in the diversion and drainage chamber 4 as filtration progresses. The vinegar flows through the arc-shaped coarse filter plate 9 in the diversion and drainage chamber 4 and is filtered through the coarse filter holes on the arc-shaped coarse filter plate 9. Large particulate impurities are intercepted on the outside of the arc-shaped coarse filter plate 9. The filtered vinegar enters the inside of the arc-shaped coarse filter plate 9 and then flows to the top of the fine filter screen 8 through the return pipe 10, which is connected to the inside of the coarse filter barrel 3 and the inside of the arc-shaped coarse filter plate 9 and is set at an incline. It then participates in fine filtration again. At the same time, the vinegar in the recovery chamber 13 is collected and discharged through the recovery pipe 14 into the recovery main pipe 16. The large particulate impurities intercepted in the diversion and drainage chamber 4 are discharged through the drainage pipe 11 on the outside of the filter barrel 2, completing the entire filtration cycle.

[0026] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. They are common knowledge in the field. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
