Embodiment Construction

[0018] The specific embodiment of the present invention will be further described in detail below in conjunction with accompanying drawing 1 .

[0019] 1. When the sampling time set by the central control machine arrives or receives a work order from the server, the following actions will be completed in sequence:

[0020] 2. The central control machine supplies power to the motor 3 through port 1, allowing the bracket and filter to drop onto the weighing pan of the electronic balance.

[0021] 3. Supply power to the electronic balance and microwave dryer through port 2 and port 3 respectively to evaporate the water on the filter paper. After T1, weigh every 5 seconds. If you weigh 5 times continuously, the weight error is less than 0.2mg , as the filter paper has been dried. Turn off the power supply of port 2 and port 3. The electronic balance sends the weighing data to the central control machine for storage.

[0022] 4. Supply power to motor 3 through port 1, and the br...

Abstract

The invention discloses a multi-functional full-automatic online monitoring device of suspended substance, which is based on gravimetric method, meets GB11901-89 norm and can complete measurement quickly. It is composed of automatic extracting system, automatic filter system, automatic washing system, automatic drying system, automatic weighing system, automatic central controlling system, data transmitting system and power system. It also can realize online measuring of other physical and chemical parameters. When need testing, central controlling system drives automatic extracting system to extract water sample which is used to clean pipes and water measuring bottle. After filling, the water measuring bottle is sent to automatic filter system for filtering. Clear filter residue and start automatic drying system to dry it, then, utilize automatic weighing system to weight. All data is calculated and saved by central controlling system and finally is transmitted to manage center by data transmitting system.

Description

technical field [0001] The invention relates to an on-the-spot rapid determination instrument and detection device for solid suspended matter content and other physical and chemical parameters in liquid. Mainly used in environmental protection, water and soil conservation, biology, medicine, chemical production and other fields. technical background [0002] At present, the method for the determination of suspended solids in water bodies stipulated by the state is the gravimetric method. The specific definition is: "Suspended solids in water quality refer to the substances that the water sample passes through the filter membrane with a pore size of 0.45um, cut and left on the filter membrane, and dried at 103~105°C to a constant weight." According to the national standard GB11901-89 It takes about 0.5-1 day to complete the laboratory test of a sample. So far, the author has not found any domestic and foreign information on the use of gravimetric methods to achieve online m...
