Description

Technical Field

[0001] The utility model relates to the technical field of water-milled glutinous rice flour processing, in particular to a device for absorbing sewage sediments from water-milled glutinous rice flour processing. Background Art

[0002] The wastewater generated during the processing of water-milled glutinous rice flour contains a high concentration of organic matter, particulate matter and glutinous rice residue. If these wastewaters are discharged directly, it will not only waste resources but also pollute the environment. Therefore, the development and use of water-milled glutinous rice flour processing wastewater sediment absorption equipment is of great significance to environmental protection and resource recovery.

[0003] After searching, the water-milled glutinous rice flour processing sewage sediment suction device with announcement number CN220223774U belongs to the technical field of glutinous rice flour processing. The water-milled glutinous rice flour processing sewage sediment suction device includes: a sedimentation tank, a sedimentation component, a water inlet pipe, a first drain pipe, and a second drain pipe. The sewage enters the sedimentation component placed in the sedimentation tank from the water inlet pipe. The sewage is accelerated to precipitate under the action of the sedimentation component. After the sewage is precipitated, the clarified part is discharged from the second drain pipe located near the edge of the sedimentation tank, and the sediment part is discharged from the first drain pipe located at the bottom of the sedimentation tank. The device can process a large amount of washing water generated in the process of glutinous rice flour processing, which is convenient for the subsequent recycling of water resources. At the same time, the particulate matter in the sewage after washing glutinous rice has a certain value, and the sedimentation collection improves the economic benefits of the factory.

[0004] Based on the above patent, the sewage used to wash glutinous rice enters the sedimentation component in the sedimentation tank through the water inlet pipe, and the sewage enters the first sedimentation chamber in the sedimentation component. The particulate matter in the sewage is precipitated under the drive of the rotating plate in the first sedimentation chamber, and part of the sewage is lifted by the rotating impeller to the second sedimentation chamber. After being filtered by the filter screen in the second sedimentation chamber, the sewage enters the second separation cover and is then discharged from the second drain pipe to complete the preliminary sedimentation of the sewage. The device can process a large amount of washing water generated in the process of glutinous rice flour, which is convenient for the subsequent recycling of water resources. At the same time, the particulate matter in the sewage after washing glutinous rice has a certain value, and sedimentation and collection improves the economic benefits of the factory. However, the stirring efficiency of the water-ground glutinous rice flour in the sedimentation tank in the patent is low, and the low stirring efficiency will cause uneven mixing of the flocculant and the suspended matter in the sewage, affecting the flocculation effect, making the sedimentation effect worse, resulting in more suspended matter remaining in the treated water, affecting the efficiency and water quality of the subsequent treatment process.
