Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wastewater detection and treatment, in particular to a centrifugal device for wastewater detection. Background Art
[0002] Wastewater refers to the general term for water discharged during residents' activities and runoff rainwater. It covers domestic sewage, industrial wastewater, and other unused water such as initial rain runoff into drainage pipes. The sources of wastewater are varied. Domestic sewage mainly comes from the daily life of families, such as rice washing water, vegetable washing water, toilet feces and urine water, bathing water, clothing washing water, etc. In order to monitor the concentration and changing trend of pollutants in wastewater, wastewater testing is required. Due to the presence of suspended particles in wastewater, errors will occur in the results of wastewater testing, and a centrifugal device is required to remove suspended particles in wastewater.
[0003] Common centrifugal devices for wastewater detection are usually composed of structures such as a liquid tank, a water inlet pipe, a separation frame, a solid-liquid separation net, and a drain pipe. The water inlet pipe guides the wastewater inside the liquid tank into the inside of the separation frame. The separation frame separates the solid particles from the liquid in the wastewater through the solid-liquid separation net during the centrifugal process, and discharges the treated wastewater through the drain pipe. This is a common structure and use method of a centrifugal device for wastewater detection. After long-term use, solid particles and other substances in traditional centrifugal devices for wastewater detection will cause blockage of the solid-liquid separation net, making it inconvenient to clean, and affecting subsequent wastewater detection, making it unusable. For example, in a centrifugal device for wastewater detection with patent number CN215276124U, a fixed rod drives the lifting scraper to rotate, and the lifting scraper can move up and down under the action of the threaded shaft to scrape off the solid particles on the inner wall of the solid-liquid separation net. However, in this method, the scraped solid particles will fall to the bottom of the inner cavity under the action of gravity to form an accumulation, and will be blocked in the solid-liquid separation net again during the centrifugation process, so that the scraped solid particles cannot be cleaned out of the device in time. Therefore, a centrifugal device for wastewater detection is proposed. Utility Model Content
