Problems solved by technology

It is inefficient to manually suck the liquid through the ear washing ball. When there are a large number of samples, it is often tedious and time-consuming, which makes the work efficiency lag behind.
Connecting the conventional liquid pump to the tap water pipe is convenient for the operator to pump liquid, but the average flow rate of the tap water pipe is 1-1.5m / s, the diameter of the tap water pipe is 2cm, and the average consumption of tap water is 1.13-1.70 tons per hour, which is a huge waste of water resources. The waste liquid from the conventional liquid pump is easy to flow away along the sewer, it is not easy to collect and treat, and it does not meet the requirements of modern energy saving and emission reduction

Abstract

The invention discloses a liquid pumping system for a recoverable waste liquid and water-saving chemical analysis and a use method of the liquid pumping system. The system comprises: a liquid container, a pipet, a glass liquid pumping device, an acidic buffering pool, an alkaline buffering pool, a corrosion-resistant chemical water pump, and a micro-computer controller, wherein a lower end of the pipet is arranged in the liquid container. A liquid inlet branch pipe of the glass liquid pumping device is connected to an upper end of the pipet, and a liquid outlet branch pipe is connected to a waste water pipe. The waste water pipe is provided with a water-flow-rate adjusting solenoid valve and an acidic-and-alkaline solenoid relay valve, and an exit of the waste water pipe is provided with a three-way unit. An acidic waste water pool is connected to one exit of the three-way unit, and an alkaline waste water pool is connected to another exit of the three-way unit. The corrosion-resistant chemical water pump is connected to a negative-pressure pipe of the glass liquid pumping device. The system can circularly pump a liquid, and separate and recycle waste water, so that waste of water resources is reduced.

Description

technical field [0001] The invention belongs to the technical field of chemistry and chemical engineering, and in particular relates to a recyclable waste liquid and a water-saving pumping system for chemical analysis and a use method thereof. Background technique [0002] Liquid pumping is a method of pumping liquid by negative pressure through the principle of hydrodynamic pressure difference. Due to the needs of scientific research and production of metallurgical chemistry and chemical industry, it is necessary to detect the content of inorganic elements in various solutions such as COD in domestic polluted water, trifluralin and other pesticide residues in soil, industrial wastewater, unit chrome plating solution, cold rolling electroplating solution, etc. Different solutions Their physical or chemical properties vary. The current method of pipetting the liquid to be tested is manually sucking through the ear washing ball, or connecting a conventional liquid pump to a w...
