Waste liquid collecting and filtering device for biological engineering flowing water refining line

Abstract

The invention provides a waste liquid collecting and filtering device for a biological engineering flowing water refining line. The device comprises a collecting barrel, a rectangular rod and a rectangular stop block; the upper part of the outer wall of the collecting barrel is provided with an observation window; the top end surface of a bottom cover is fixedly connected with the rectangular column; the rectangular column is internally provided with a U-shaped channel; and the rectangular rod is slidably connected in a rectangular pipe. Through cooperative arrangement of the collecting barrel, the bottom cover and the rectangular column, the U-shaped channel is formed in the rectangular column, a rectangular hole is formed at the lower part of the left end surface of the rectangular column, and the rectangular hole communicates with the U-shaped channel, so that on the one hand, when the liquid level reaches the top position of the U-shaped channel in the rectangular column, a liquidin the collecting barrel is discharged out of the device through the U-shaped channel; and on the other hand, the water discharge speed is higher than the water inlet speed, so that after filtered wastewater in the collecting barrel is completely discharged, a certain interval exists before water discharge of the next time, and then a water receiving barrel can be replaced at the moment.

Description

technical field [0001] The invention belongs to the technical field of bioengineering collection and filtration devices, and more specifically relates to a waste liquid collection and filtration device used in bioengineering water refining lines. Background technique [0002] In many processes, liquid materials need to be filtered to remove impurities or other pollutants, such as: for bioengineering water extraction lines. Filtration is often accomplished by letting the liquid flow through the filter material; the usual method refers to a process in which the fluid is injected into the filter device and passed through a filter material such as a multi-layer filter for multiple filtration, and then discharged from the filter device after filtration. However, after filtering for a period of time, especially at the filter screen at the bottom, it is easy to cause the filter screen to be clogged due to the sedimentation and accumulation of debris, and the filtration efficiency i...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a waste liquid collection and filtration device for bioengineering water extraction line to solve the problem that the existing waste liquid collection and filtration device for bioengineering water extraction line is relatively short. When filtering, because the waste liquid contains a lot of sundries, after filtering for a period of time, especially at the filter screen at the bottom, the filter screen is likely to be blocked due to the sedimentation and accumulation of sundries, causing the drainage speed to slow down. , needs to be dismantled for cleaning and maintenance, which affects the filtration efficiency to a certain extent; the circulation automation is not convenient enough, and the collection and filtration devices used on the existing water refining line often need to be replaced when the next water receiving bucket is full. After manually closing the filter device to replace the water receiving bucket, it is not possible to adjust the corresponding water receiving line to automatically receive water according to the drainage time period to improve the degree of automation; the filtering effect is poor. The number of filter screens cannot achieve multi-layer filtration in a small space through structural improvements
