Description

Technical Field

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

[0002] Baijiu brewing is a complex and historically significant process that primarily utilizes starchy raw materials such as grains. Through the saccharification and fermentation processes of microorganisms, the alcoholic beverage is ultimately obtained through distillation.

[0003] In baijiu production, filtration devices are mainly used in three core stages: before base liquor storage, after blending, and before finished product bottling. Their core function is to remove impurities and improve the purity and stability of the liquor. Among these, membrane filters, due to their high precision, ease of operation, and ability to effectively ensure liquor clarity, are primarily used for filtration after blending and before finished product bottling.

[0004] Common membrane modules include hollow fiber, spiral wound, tubular, and plate and frame types. Their basic principle is to force liquid through a microporous membrane under pressure, achieving solid-liquid separation or sterilization. Traditional membrane filtration devices typically consist of a housing, membrane module, inlet and outlet pipes, and end caps. The liquid to be filtered enters the membrane module through the inlet, flows across the membrane surface, and some liquid permeates through the membrane to become the filtrate, while impurities are retained to form a concentrate which is then discharged.

[0005] In actual operation, existing membrane filtration devices generally suffer from problems such as uneven flow field distribution, severe concentration polarization, easy fouling of membrane surfaces, and rapid flux decay. Especially in the inlet area, due to unreasonable flow channel design, eddies, dead water zones, or local high-concentration zones are easily formed, causing the deposition of fine particles, colloidal substances, or organic matter on the membrane surface, accelerating the formation of filter cake and reducing filtration efficiency. Utility Model Content

[0006] This utility model provides a filtration device for liquor brewing. By fixing a guide plate to the inner wall of the liquid inlet 402, the flow state of the fluid entering the membrane module is improved, thereby improving the overall filtration efficiency and equipment performance. This solves the problem of unreasonable flow channel design and reduced filtration efficiency mentioned in the background art.

[0007] This utility model provides the following technical solution: A filtration device for brewing baijiu (Chinese liquor) includes a base and at least one filter cartridge for mounting a membrane module. The top of the filter cartridge is detachably connected to a top cover, and a sealing plate is fixedly connected to one end of the top cover extending into the filter cartridge. An inlet hole is provided on the sealing plate. The top and bottom of the membrane module abut against the bottom of the sealing plate and the inside of the filter cartridge, respectively, and the inlet hole communicates with the inside of the membrane module. A guide plate is fixedly connected to the inner wall of the inlet hole. A water pump is fixedly connected to the base, and the output end of the water pump is connected to the inlet end of the filter cartridge.

[0008] As a preferred embodiment of the present invention, the filter cartridge includes a first filter cartridge and a second filter cartridge. The output end of the first filter cartridge is connected to the liquid inlet end of the second filter cartridge through a connecting pipe, and the output end of the second filter cartridge is fixedly connected to a drain pipe with a valve.

[0009] As a preferred embodiment of this utility model, both the bottom of the first filter cartridge and the bottom of the second filter cartridge are fixedly connected to a drain pipe with a valve.

[0010] As a preferred embodiment of this utility model, one end of the water pump is fixedly connected to an inlet pipe, and the other end of the water pump is fixedly connected to a delivery pipe. The end of the delivery pipe away from the water pump is connected to the inlet end of the first filter cartridge.

[0011] As a preferred embodiment of this utility model, the side wall of the sealing disc is provided with an annular sealing groove, and a serrated sealing ring is installed in the sealing groove. The outer wall of the sealing ring abuts against the inner wall of the filter cartridge, and the outlet of the conveying pipe is located above the sealing disc.

[0019] 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.

[0020] Example: Reference Figures 1-4A filtration device for brewing baijiu (Chinese liquor) includes a base 1, which is a frame structure. Casters with brakes are fixedly connected to the base plate of the base 1 for easy movement. It also includes at least one filter cartridge for mounting a membrane module 5, preferably two cartridges: a first filter cartridge 3 and a second filter cartridge 301, to achieve two-stage filtration. The membrane module 5 used in the first filter cartridge 3 is a microfiltration membrane with a filtration accuracy range of 0.1-10 μm, preferably 0.45 μm. The membrane module 5 used in the second filter cartridge 301 is an ultrafiltration membrane with a filtration accuracy range of 50-100 nm, preferably 80 nm. A top cover 4 is detachably connected to the top of the filter cartridge, preferably bolted to the top. A pressure gauge is installed on the top of the top cover 4 to detect the pressure inside the filter cartridge. A first sealing gasket is provided at the connection between the top cover 4 and the filter cartridge to improve the sealing effect between the top cover 4 and the top of the filter cartridge. A sealing disc 401 is fixedly connected to one end of the top cover 4 extending into the filter cartridge. An inlet hole 402 is provided on the sealing disc 401. The top and bottom of the membrane module 5 abut against the bottom of the sealing disc 401 and the inside of the filter cartridge, respectively. In addition, a second sealing gasket is installed on the top and bottom of the membrane module 5 to achieve a seal between the top and bottom of the membrane module 5 and the sealing disc 401 and the filter cartridge. An inlet space is formed between the top of the sealing disc 401, the inner wall of the top cover 4, and the filter cartridge at the top of the sealing disc 401. The inlet hole 402 communicates with the inside of the membrane module 5. A guide plate 403 is fixedly connected to the inner wall of the inlet hole 402. That is, the wine enters the inlet space and then enters the membrane module 5 through the inlet hole 402. The filtrate passes through the filter membrane and can be discharged through the output end of the filter cartridge. The impurities retained are collected at the bottom of the membrane module 5 for subsequent processing. A water pump 2 is fixedly connected to the base 1. The water pump 2 is preferably a sanitary centrifugal pump, model IHW50-100. Connect the output end of water pump 2 to the inlet end of the filter cartridge, that is, to the inlet space, to deliver the wine into the filter cartridge and filter it under pressure. In addition, all parts that come into contact with the wine must be made of 304 or 316L stainless steel, and the seals must be made of food-grade silicone or fluororubber (to prevent odor from leaching out).

[0021] In use, by opening a liquid inlet hole 402 on the sealing plate 401 and fixing a guide plate 403 to the inner wall of the liquid inlet hole 402, the flow state of the wine entering the membrane module 5 can be significantly improved, thereby improving the overall filtration efficiency and equipment performance.

[0022] Reference Figure 1 and Figure 2The filter cartridges include a first filter cartridge 3 and a second filter cartridge 301. The output end of the first filter cartridge 3 is connected to the inlet end of the second filter cartridge 301 via a connecting pipe 303, achieving series connection. A drain pipe 304 with a valve is fixedly connected to the output end of the second filter cartridge 301 for convenient discharge of the filtered wine. Furthermore, the volume of the second filter cartridge 301 is larger than that of the first filter cartridge 3, which improves efficiency, extends lifespan, and ensures stability. The first-stage coarse filtration removes large particles of impurities, which can be achieved with a small volume; the second-stage fine filtration needs to remove more tiny impurities, and the larger volume provides greater space for dirt to accumulate, preventing premature clogging and reducing the frequency of filter cartridge replacement. At the same time, the larger volume filter cartridge reduces fluid resistance, maintains stable flow, and allows for uniform fluid distribution, reducing the risk of impurities "penetrating" and ensuring filtration effectiveness.

[0023] Reference Figure 2 Both the bottom of the first filter cartridge 3 and the bottom of the second filter cartridge 301 are fixedly connected to a drain pipe 302 with a valve. After use, the drain pipe 302 can be opened to discharge the trapped impurities, thereby improving the performance.

[0024] Reference Figure 3 An inlet pipe 201 is fixedly connected to one end of the water pump 2, and a delivery pipe 202 is fixedly connected to the other end of the water pump 2. The end of the delivery pipe 202 away from the water pump 2 is connected to the inlet end of the first filter cartridge 3. A valve is fixedly connected to the delivery pipe 202, which not only facilitates the delivery of wine into the filter cartridge, but also increases the pressure of the wine, thereby improving the filtration effect and efficiency.

[0025] Reference Figures 2-4 A ring-shaped sealing groove is provided on the side wall of the sealing disc 401. A serrated sealing ring 6 is installed in the sealing groove, and the outer wall of the sealing ring 6 abuts against the inner wall of the filter cartridge. The outlet of the delivery pipe 202 is located above the sealing disc 401, that is, the outlet of the delivery pipe 202 is connected to the liquid inlet space. In use, the sealing ring 6 installed on the side wall of the sealing disc 401 can improve the sealing effect between the outer wall of the sealing disc 401 and the inner wall of the filter cartridge, thereby improving the performance.

[0026] Reference Figure 3 The guide plate 403 is a spiral plate, which forces the fluid to begin rotating before entering the membrane module 5, forming a composite flow of axial and circumferential directions. This enhances the fluid's kinetic energy and turbulence. The swirling flow effectively washes the wall surface near the inlet, preventing impurities from depositing in corners or connections, reducing "dead water zones," and allowing the fluid to be more evenly distributed on the subsequent membrane surface or filtration area. This avoids excessively high or low local flow velocities and reduces concentration polarization. Of course, in other embodiments, the guide plate 403 can be a straight plate, with six straight plates evenly arranged circumferentially along the flow direction. This straight plate can rectify the flow and reduce eddies and energy dissipation at the inlet.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
