Abstract

The invention relates to a water-saving device in a chemistry lab combining a ventilation mechanism in a lab, belonging to the field of water collection and distribution. The invention aims at solvingthe problem of waste of the water resource for cooling in the experiment process of basic teaching for the department of chemistry in colleges and universities. The water-saving device comprises a distributing pipe, a collecting pipe, a cross flow cooling tower, a water pump and a ventilation kitchen. A water outlet port of the cross flow cooling tower is communicated with a water inlet port of the water pump; the water outlet port of the water pump is communicated with the distributing pipe; the water inlet port of the cross flow cooling tower is communicated with the collecting pipe; both the collecting pipe and the distributing pipe are provided with a plurality of taps; and the side wall of the ventilation kitchen is provided with a branch air port which is communicated with an air vent of the cross flow cooling tower. The scheme breaks through the usual thought and behavior that the tap water is directly used as cooling water and is waste after flowing through the device in the experiment process of basic teaching for the department of chemistry in colleges and universities. The device is beneficial to solving the problem of water resource waste.

Description

technical field [0001] The invention relates to a chemical laboratory water-saving device combined with a laboratory ventilation mechanism, which belongs to the field of water collection and distribution of E03B. Background technique [0002] In the basic teaching laboratories used for basic professional skills training in the chemistry departments of various universities, many of the chemical experiments arranged all year round involve distillation or heating and reflux operations. When dozens or even hundreds of students carry out such experiments at the same time , it can be seen that the cooling water outlets of several sets of devices or even dozens of sets of devices directly lead to the sewer, which is equivalent to several or even dozens of faucets that are open at the same time and directly discharge water to the sewer. It is drawn from tap water, just circulates in the device and then discharged into the sewer. If you pay attention to this phenomenon, you will know...
