Description

Technical Field

[0001] This utility model relates to the field of alcohol production technology, specifically to a waste liquid treatment device for alcohol production. Background Technology

[0002] Industry is a crucial foundational raw material industry for the national economy. Alcohol is widely used in chemical, food, daily chemical, and pharmaceutical industries, serving as a base for alcohol production, an extractant, a solvent, a detergent, and a surfactant. Pollution from alcohol residues in alcohol plants is one of the most serious sources of pollution in the food and fermentation industries. Due to factors such as investment, production scale, technology, and management, most alcohol plants have low comprehensive utilization rates. Alcohol wastewater is high-concentration, high-temperature, and high-suspended-solids organic wastewater. Treatment technology for alcohol wastewater started early and has developed rapidly. The waste residue in the waste liquid contains coarse fibers such as crushed cassava peel and roots, which are insoluble COD in the wastewater. Cellulose and hemicellulose in cassava are polysaccharides that cannot be utilized as carbon sources by yeast during alcohol fermentation and remain in the waste liquid, manifesting as soluble COD. Inorganic ash and sand impurities further complicate wastewater treatment.

[0003] In the treatment of alcohol wastewater, solid-liquid separation is usually adopted to improve the utilization efficiency of waste liquid. The filtrate is reused in production or treated with biochemical methods to meet standards, and the filter residue is directly used as feed. However, in the process of solid-liquid separation, the traditional static setting method is slow and the solid-liquid separation is not thorough enough. Therefore, filtration separation method has been developed. In order to avoid the fact that there are many solid impurities in the waste liquid, the filter screen made of gauze will affect the separation speed. Therefore, we propose a waste liquid treatment equipment for alcohol production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a waste liquid treatment device for alcohol production, which solves the problems of slow solid-liquid separation speed and low separation efficiency mentioned in the background technology.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a waste liquid treatment device for alcohol production, including a support frame, a filter element supported inside the support frame, a liquid extraction tank fixedly mounted outside the support frame, an air pump fixedly supported outside the liquid extraction tank, and a drain pipe fixedly supported outside the liquid extraction tank.

[0006] Optionally, the vertical cross-section of the drain pipe is L-shaped, a support plate is fixedly fitted inside the drain pipe, a sealing ring is fixedly fitted inside the drain pipe, and a sealing ball is provided between the sealing ring and the support plate.

[0007] Optionally, a telescopic column is fixedly supported on the top of the liquid extraction tank, a connecting frame is fixedly connected to the top of the output shaft of the telescopic column, a feeding plate is fixedly fitted inside the inner cavity of the connecting frame, a sealing frame is fixedly connected to the bottom of the connecting frame, and a guide block is fixedly supported on the bottom surface of the inner cavity of the sealing frame.

[0008] Optionally, the inner cavity of the drain pipe and the inner cavity of the suction tank are interconnected, and the air pump is an air pumping pipe that extends into the interior of the suction tank.

[0009] Optionally, the support plate has a through-hole water outlet inside, the top inner diameter of the sealing ring is greater than the bottom diameter, and the diameter of the sealing ball is greater than the top inner diameter of the sealing ring.

[0010] Optionally, the support frame consists of two upper and lower support rings and a support rod between the two support rings, and the sealing frame consists of a support plate, a support, and a connecting column above. The connecting column is movably fitted inside the support rod, and the support plate is located below the lower support ring.

[0011] This utility model provides a waste liquid treatment device for alcohol production, which has the following beneficial effects:

[0012] 1. This waste liquid treatment equipment for alcohol production, through the setting of support frame and filter element, has a liquid extraction tank fixedly installed on the outside of the support frame. After the upper and lower parts of the support frame are sealed, the air pump set on the outside of the liquid extraction tank can reduce the air pressure between the liquid extraction tank and the support frame, thereby assisting the liquid to quickly pass through the filter element to complete filtration. At the same time, the drain pipe can cooperate to drain the liquid, and the sealing ball and sealing ring will cooperate to seal the drain pipe during the negative pressure process of the air pump, ensuring filtration efficiency.

[0013] 2. This waste liquid treatment equipment for alcohol production has a sealing frame that is movably installed inside the support frame. The bottom surface of the sealing frame is fixedly supported by a guide block, which can help control the sealing or opening of the bottom surface of the support frame. At the same time, the telescopic column can control the position of the sealing frame and the guide block by controlling the position of the connecting frame, which facilitates the use of the equipment. The cooperation of the discharge plate can perform sealing and discharge. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a waste liquid treatment device for alcohol production, including a support frame 1, with a filter element 2 internally supported. The support frame 1 and the filter element 2 work together to filter the waste liquid during use. A liquid extraction tank 3 is fixedly installed on the outside of the support frame 1. The liquid extraction tank 3 can seal the outside of the support frame 1, thereby forming a separation space, which can facilitate rapid solid-liquid separation and waste liquid collection. An air pump 4 is fixedly supported on the outside of the liquid extraction tank 3. The air pump 4 can work with the negative pressure inside the liquid extraction tank 3. A drain pipe 5 is fixedly supported on the outside of the liquid extraction tank 3. The drain pipe 5 can facilitate rapid and stable drainage, making the equipment convenient to use.

[0021] The vertical cross-section of the drain pipe 5 is L-shaped. The inner cavity of the drain pipe 5 is fixedly fitted with a support plate 8 and a sealing ring 6. A sealing ball 7 is set between the sealing ring 6 and the support plate 8. The drain pipe 5 is designed to cooperate with the draining. The sealing ring 6 and the sealing ball 7 in the inner cavity, together with the support plate 8, can cooperate to seal the drain pipe 5 during the air pumping process of the air pump 4.

[0022] The top of the liquid extraction tank 3 is fixedly supported by a telescopic column 9. The top of the output shaft of the telescopic column 9 is fixedly connected to a connecting frame 10. The inner cavity of the connecting frame 10 is fixedly fitted with a feeding plate 13. The bottom of the connecting frame 10 is fixedly connected to a sealing frame 11. The bottom surface of the inner cavity of the sealing frame 11 is fixedly supported by a guide block 12.

[0023] The inner cavity of the drain pipe 5 is connected to the inner cavity of the liquid extraction tank 3. The air pump 4 is an air extraction pipe that extends into the interior of the liquid extraction tank 3. The cooperation between the air pump 4 and the drain pipe 5 can effectively improve the filtration efficiency and increase the speed and efficiency of waste liquid treatment.

[0024] The support plate 8 has a through-hole. The inner diameter of the top surface of the sealing ring 6 is larger than the diameter of the bottom surface, and the diameter of the sealing ball 7 is larger than the inner diameter of the top surface of the sealing ring 6. During the process of the air pump 4 evacuating the inner cavity of the liquid extraction tank 3, the airflow will push the sealing ball 7 upward, so that the sealing ball 7 fits against the bottom surface of the sealing ring 6, thereby sealing the sealing ring 6 and thus sealing the drain pipe 5.

[0025] The support frame 1 consists of two upper and lower support rings and a support rod between the two support rings. The sealing frame 11 consists of a support plate, a support, and a connecting column above. The connecting column is movably fitted inside the support rod, and the support plate is located below the lower support ring.

[0026] In summary, this waste liquid treatment equipment for alcohol production operates as follows: First, the output shaft of the telescopic column 9 is controlled to push the connecting frame 10 upward, which in turn drives the sealing frame 11 upward. The sealing frame 11 then seals the bottom of the support frame 1. Subsequently, the solid-liquid mixture waste material produced during production is injected into the inner cavity of the support frame 1 through the feeding plate 13, sealing the top of the feeding plate 13. Then, the vacuum pump 4 is started, and the output shaft of the vacuum pump 4 controls the space inside the liquid extraction tank 3 located outside the support frame 1 to be under negative pressure for a period of time. This allows the liquid inside the support frame 1 to pass through the filter element 2 and then flow to the outside through the drain pipe 5. During the vacuum pump 4's suction process, the sealing ball 7 is adsorbed and seals the sealing ring 6, thus ensuring the overall sealing effect and improving the efficiency of solid-liquid separation. After the solid-liquid separation is completed, the output shaft of the telescopic column 9 is retracted, and the output shaft of the telescopic column 9 drives the connecting frame 10 and the sealing frame 11 downward, opening the bottom of the support frame 1 and discharging the waste material.
