Description

Technical Field

[0001] This utility model relates to the field of distillers' grains filtrate treatment technology, and in particular to a distillers' grains filtrate recycling device. Background Technology

[0002] In the production of alcoholic beverages or fermented foods (such as rice wine), the liquid portion extracted from the lees using solid-liquid separation technology is called lees filtrate. This liquid is rich in various soluble nutrients, including proteins, vitamins, fats, and yeast cells, giving it significant nutritional value and reuse potential. However, the high viscosity and acidity of lees filtrate, along with its relatively low solids content, pose challenges for subsequent processing. Through technologies such as evaporation concentration or membrane separation, the nutrients in lees filtrate can be effectively recovered and then dried into feed additives (such as DDS or DDGS) for use in animal husbandry. Furthermore, lees filtrate can also be recycled in the production process, such as during raw material soaking or slurry preparation, to achieve sustainable resource utilization.

[0003] Several mature technologies have been developed and applied for the treatment of distiller's grains filtrate. For example, the use of multi-effect evaporation can significantly reduce energy consumption, while membrane separation technology can efficiently concentrate the filtrate and recover its useful components. These technologies provide solid technical support for the resource utilization of distiller's grains filtrate.

[0004] In practical applications, the treatment of distiller's grains filtrate faces numerous challenges, particularly the difficulty in reusing the waste liquid after nutrient removal. Direct discharge of this waste liquid not only wastes water resources but may also pollute the environment. Although existing filtration systems can effectively remove impurities, subsequent storage and disinfection processes require additional time and space, which limits the efficiency of waste liquid diversion and treatment to some extent.

[0005] The filtration system is only one part of the distillers' grains filtrate treatment process. Subsequent storage and sterilization steps not only increase the complexity of the process but also raise treatment costs. Due to the characteristics of distillers' grains filtrate and the limitations of the treatment process, wastewater diversion becomes complicated, which may result in the wastewater not being effectively utilized or treated during the treatment process, thereby exacerbating environmental pressure and resource waste. Utility Model Content

[0006] The main purpose of this invention is to provide a recycling device for distiller's grains filtrate, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A recycling device for lees filtrate includes a sedimentation tank, a filter tank, an inlet, an inspection port, and a drain port. The filter tank is installed at the lower end of the sedimentation tank, the inlet is installed on the upper part of the side wall of the sedimentation tank, and the inspection port and drain port are respectively installed on the side wall and the lower part of the filter tank. A stirring assembly is installed at the upper sealing cap of the sedimentation tank. The stirring assembly agitates the liquid inside the sedimentation tank and agitates the surface of the filter layer in the filter tank to prevent clogging. The drain outlet is connected to a first ultraviolet disinfection tank via an infusion pipe, and the first ultraviolet disinfection tank is connected to a second ultraviolet disinfection tank via a connecting pipe. The second ultraviolet disinfection tank is connected to a pump body via a water pumping pipe, and the other end of the pump body is connected to a drain pipe. Electrically controlled valves are installed on the drain pipe and the water pumping pipe. The pump body is used to extract the filtered water from the lees press filtrate for recycling.

[0008] Alternatively, the side wall of the sedimentation tank is provided with a treatment agent interface, through which a sedimentation treatment agent is injected. The stirring assembly includes a stirring motor, a stirring rod, and stirring blades. The stirring motor is bolted to the sealing cover of the sedimentation tank, and the stirring rod is bolted to the output end of the stirring motor. Multiple stirring blades are distributed on the stirring rod. The stirring assembly is used to mix the filtrate from the distiller's grains and the sedimentation treatment agent in the sedimentation tank. Alternatively, the infusion pipeline is connected to the drain outlet via a connecting flange, and a sealing ring is provided at the connection. The infusion pipeline is installed on the top of the first ultraviolet disinfection tank, and a valve is provided at the connection between the first ultraviolet disinfection tank and the infusion pipeline. Alternatively, ultraviolet lamps are installed on the top covers of the first and second ultraviolet disinfection and sterilization tanks, and treatment agent interfaces are provided on the side walls of the first and second ultraviolet disinfection and sterilization tanks, so that dual storage and multi-level sterilization operations can be achieved through the two ultraviolet disinfection and sterilization tanks. Alternatively, the water pumping pipe is connected to the second ultraviolet disinfection tank via a connector and a connecting flange, and a sealing ring is provided at the connection. An instrument is provided on the side wall of the drain pipe to record the flow rate data of the drain pipe. Alternatively, the electrically controlled valve is a ball valve, which is connected to the water pump pipe and the drain pipe via a connecting flange, and a sealing ring is provided at the connection.

[0009] Compared with the prior art, the present invention has the following beneficial effects: By combining a sedimentation tank and a filtration tank, effective sedimentation and filtration of the distiller's grains filtrate are achieved, removing impurities and particulate matter from the liquid and improving its clarity and purity.

[0010] The multi-stage storage and ultraviolet disinfection design allows the initially filtered liquid to undergo further ultraviolet disinfection, effectively killing bacteria, viruses, and other harmful microorganisms in the liquid and ensuring its hygiene and safety. At the same time, the multi-stage storage facilitates step-by-step processing and monitoring of the liquid, improving processing efficiency and flexibility.

[0011] The pumping mechanism allows the disinfected liquid to be extracted and recycled in a timely manner, saving water resources and reducing treatment costs. The precise control of the electronically controlled valves further enhances the intelligence and automation of the entire recycling process. Attached Figure Description
