Description

Technical Field

[0001] The utility model relates to the technical field of cocoon silk waste liquid treatment, in particular to a cocoon silk waste liquid biochemical treatment solid-liquid separation device. Background Art

[0002] Cocoon silk is a filamentous substance formed by the protein secreted by the silk glands of silkworm pupae. It is a natural fiber material. During the extraction and processing of cocoon silk, waste liquid containing organic substances such as cocoon silk protein, fat and protease will be produced. The waste liquid is usually acidic or alkaline. In order to prevent it from polluting the environment, it needs to be purified. After that, the purified liquid needs to separate the filtrate from the residue.

[0003] The existing solid-liquid separation device is based on a tank body, with a filter installed inside the tank body, a feed pipe arranged on the top side of the tank body, an output pipe arranged on the bottom side of the tank body, and a water pump fixed on the side of the tank body. The input end of the water pump is connected with the output pipe through a conduit, and the output end of the water pump is connected with the feed pipe through a water pipe. The treated waste liquid is added through the feed pipe, at which time the filter removes the filter residue in the waste liquid, and the filtered liquid is discharged from the output pipe. At the same time, the water pump is controlled to transport the filtered liquid back to the feed pipe for filtering again to ensure solid-liquid separation and facilitate subsequent processing.

[0004] However, after the current solid-liquid separation device is used for a long time, the filter residue will adhere to the surface of the filter screen, resulting in reduced filtration efficiency. At this time, it needs to be disassembled and cleaned, which reduces the working efficiency of the solid-liquid separation device. Therefore, a solid-liquid separation device for biochemical treatment of cocoon silk waste liquid is proposed. Utility Model Content

[0005] In order to make up for the shortcomings of the prior art, after long-term use of the solid-liquid separation device on the market, the filter residue will adhere to the surface of the filter screen, resulting in reduced filtration efficiency. At this time, it is necessary to dismantle it for cleaning, which reduces the working efficiency of the solid-liquid separation device. The utility model proposes a solid-liquid separation device for biochemical treatment of cocoon silk waste liquid.

[0006] The technical solution adopted by the utility model to solve its technical problems is: the solid-liquid separation device for biochemical treatment of cocoon silk waste liquid described in the utility model comprises a tank body; a filtering mechanism is arranged on one side of the tank body, a fixing mechanism is arranged on the inner side of the filtering mechanism, a sealing mechanism is arranged on the circumferential surface of the tank body, and a fixing platform is fixed on the circumferential surface of the tank body.

[0011] 1. The utility model adopts the structural design of a solid-liquid separation device for biochemical treatment of cocoon silk waste liquid. By setting a filtering mechanism, the treated waste liquid is added through the feed inlet. At this time, the filter screen filters out fixed impurities in the waste liquid, and the filtered liquid is discharged through the discharge port on the bottom side of the tank body, thereby using solid-liquid separation. If the filter screen is blocked during use, resulting in a decrease in its solid-liquid separation efficiency, the positioning rod is pulled out, and the servo motor is controlled to drive the rotating table to rotate, thereby moving the inner filter screen of the tank body out and the outer filter screen into the inner side of the tank body.

[0026] Working principle: cocoon silk is the filamentous substance formed by the secretion of protein from the silk gland of silkworm pupa, and is a natural fiber material. During the extraction and processing of cocoon silk, waste liquid containing organic substances such as cocoon silk protein, fat and protease will be produced, and the waste liquid is usually acidic or alkaline. In order to prevent it from polluting the environment, it needs to be purified, and then the purified liquid needs to separate the filtrate from the filter residue. After the existing solid-liquid separation device is used for a long time, the filter residue will adhere to the surface of the filter structure, resulting in a decrease in the filtration efficiency. At this time, it needs to be dismantled and cleaned, which reduces the working efficiency of the solid-liquid separation device. In order to solve this problem, a filtering mechanism and a fixing mechanism are set, and the treated waste liquid is added through the feed port 21. At this time, the filter screen 9 filters out the fixed impurities in the waste liquid, and the filtered liquid is discharged through the discharge port 22 on the bottom side of the tank body 1, thereby using solid-liquid separation. If the filter screen 9 is blocked during use, resulting in a decrease in its solid-liquid separation efficiency, the positioning rod 6 is pulled out, The servo motor 3 is controlled to drive the rotating table 4 to rotate, so as to move the filter screen 9 inside the tank body 1 out and move the outer filter screen 9 into the inner side of the tank body 1. At this time, the outer filter screen 9 can be pushed to rotate inside the mounting frame 8 so that the filter screen 9 is perpendicular to the ground. At this time, the solid impurities on its surface can be scraped off and its surface can be rinsed. After the rinsing is completed, the filter screen 9 is pushed to be horizontal. At this time, under the action of the elastic force of the first spring 14, the card block 13 is driven to be buckled on the inner side of the fixing hole 11 to fix the position of the filter screen 9. Similarly, the servo motor 3 is controlled to move the cleaned filter screen 9 to the inner side of the tank body 1. The mounting frame 8 is buckled between the sealing rings 15, and the sealing ring 10 on its surface is tightly fitted with the tank body 1. At the same time, the second spring 19 is in a compressed state, which pushes the sealing ring 15 to be tightly attached to both sides of the mounting frame 8 and the circumferential surface of the tank body 1, thereby ensuring that the inner side of the tank body 1 is in a closed environment, preventing the leakage of waste liquid during the solid-liquid separation process, and solving the problem of low working efficiency of the existing solid-liquid separation device.
