Description

Technical Field

[0001] This utility model relates to the field of filter tank technology, and in particular to a filter tank for liquor production. Background Technology

[0002] Baijiu (Chinese liquor) filtration equipment is a core component in industrial production to ensure the quality of the liquor. The mainstream design is a tank-type structure, consisting of a filter tank, filter cartridges, inlet and outlet pipelines, and a pressurization system. Based on filter cartridge type, it can be divided into activated carbon filter tanks, diatomaceous earth filter tanks, and polymer membrane filter tanks. During operation, baijiu enters the tank under pump pressure, flows through the filter cartridges, and undergoes mechanical sieving to intercept impurities such as starch particles and microbial cells. Some equipment incorporates activated carbon filters to adsorb pigments and off-flavor substances, ultimately outputting a clarified liquor.

[0003] Existing filtration equipment has obvious technical shortcomings: First, it lacks low-temperature control function and has difficulty removing higher fatty acid ethyl esters. These substances are in molecular form at room temperature and cannot be intercepted. The tiny crystals that precipitate at low temperatures easily clog the filter element, resulting in a sharp drop in filtration efficiency and incomplete removal. This makes the liquor prone to turbidity at low temperatures. Second, it has poor adaptability to low-alcohol liquor. Low-alcohol liquor is prone to freezing in low-temperature environments, which prevents crystals from precipitating.

[0004] Therefore, this application provides a filter tank for liquor production. Utility Model Content

[0005] This invention provides a filter tank for liquor production, which can effectively solve the problems of existing equipment being unable to efficiently remove high-grade fatty acid ethyl esters and low-alcohol liquor being prone to freezing at low temperatures.

[0028] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Example

[0030] like Figures 1 to 4 As shown, this application provides a filter tank for liquor production, comprising:

[0031] The tank body 10 has a cooling chamber 11 and a filter chamber 12 arranged inside. The bottom of the cooling chamber 11 is equipped with a guide plate 13, and the bottom of the filter chamber 12 is fixedly installed with a filter element 14. The lower side of the tank body 10 is integrally provided with a discharge port 15. The upper end of the filter element 14 is fixedly connected to the bottom of the guide plate 13. The liquor first enters the cooling chamber 11 to cool down, causing the higher fatty acid ethyl esters and other substances contained therein to precipitate out. Then it enters the filter chamber 12 and is filtered by the filter element 14. The filtered liquor is discharged through the discharge port 15.

[0032] In one optional embodiment, a fixing ring 17 is fixedly installed on the lower end of the outer wall of the tank 10, and a plurality of equally spaced support legs 18 are welded to the outer wall of the fixing ring 17. The equipment is supported by the support legs 18 in conjunction with the fixing ring 17.

[0033] In an alternative embodiment, the baffle 13 is arranged in a conical structure so that substances such as high fatty acid ethyl esters that precipitate at low temperatures can be smoothly discharged from the inner wall of the baffle 13.

[0034] The sealing cap 20 is fixedly installed on the top of the tank body 10 by bolts. The top of the tank body 10 is integrally provided with a feed port. The sealing cap 20 seals the tank body 10 to prevent the liquor from evaporating and external impurities from entering.

[0035] The cooling mechanism 30 includes a heat exchange tube 31 fixedly installed inside the cooling chamber 11 and a coolant tank 32 fixedly installed on the outer wall of the upper end of the tank body 10. A water pump is installed inside the coolant tank 32, and the output end of the water pump is fixedly connected to one end of the heat exchange tube 31, while the other end of the heat exchange tube 31 is fixedly connected to the outer wall of the coolant tank 32.

[0036] In an optional embodiment, control buttons and a display screen are provided on the outside of the cooling mechanism 30.

[0037] After adopting the above technical solution, the liquor to be filtered is poured into the cooling chamber 11. At this time, the ethylene glycol solution in the coolant tank 32 is pumped into the heat exchange tube 31 to exchange heat with the liquor in the cooling chamber 11. Under the action of heat exchange, the temperature of the liquor drops steadily, thereby causing substances such as higher fatty acid ethyl esters in the liquor to precipitate. Since the cooling is carried out by heat exchange, for low-alcohol liquor, the water molecules in it have enough time to adapt to the temperature change and are not easily disturbed by excessive local temperature difference, thus making it less likely to freeze. The liquor that has precipitated higher fatty acid ethyl esters and other substances enters the filter element 14 through the guide plate 13, filters the impurities in the liquor through the filter element 14, and finally discharges through the discharge port 15.

[0038] The cleaning mechanism 40 is located inside the filter element 14. The cleaning mechanism 40 cleans the filter element 14 to prevent impurities from clogging the gaps of the filter element 14 and causing a decrease in filtration efficiency.

[0039] In an optional embodiment, the cleaning mechanism 40 includes an inlet 41 and an outlet 42 fixedly installed at the bottom of the tank 10, and a guide column 43 fixedly installed inside the filter chamber 12. The inlet 41 and the outlet 42 are both in communication with the inside of the filter element 14. A cleaning plate 44 is slidably connected to the outer wall of the guide column 43. Water for cleaning enters the inside of the filter element 14 through the inlet 41. The cleaning plate 44 moves upward along the guide column 43 under the influence of water impact. During the upward movement of the cleaning plate 44, it contacts the inner wall of the filter element 14, thereby scraping off the impurities adhering to the inner wall of the filter element 14.

[0040] In one optional embodiment, adjusting plates 45 are hinged to both sides inside the cleaning plate 44, and baffles 46 are integrally provided on both the left and right sides of the upper surface of the cleaning plate 44. During the process of the cleaning plate 44 rising, the adjusting plates 45 are combined with the cleaning plate 44 due to the obstruction of the baffles 46, thereby generating resistance to the water flow, so that the cleaning plate 44 can move upward under the influence of water force. When the cleaning plate 44 reaches the highest point and loses the influence of water force, the adjusting plates 45 naturally droop under the influence of gravity, and the impurities that are easy to scrape off are discharged through the gap between the adjusting plates 45 and the cleaning plate 44.

[0041] In one optional embodiment, an electromagnet 47 is fixedly installed on the top of the guide post 43, and an iron block 48 is fixedly installed in the middle of the upper surface of the cleaning plate 44. When the cleaning plate 44 moves to the top of the guide post 43, the iron block 48 is magnetically attracted and fixed by the electromagnet 47.
