Demonstration table for teacher in chemical laboratory

Abstract

The invention discloses a demonstration table for a teacher in a chemical laboratory. The demonstration table mainly comprises a framework (1), a table top (2), a side plate (3), an instruction case (4), a control panel (5), a water feeding and discharging part (6) and a ventilation part (7), wherein the main body framework of the demonstration table is of a plastic steel structure, the table top, the side plate and the panel of the instruction case are made of an imported solid-core physicochemical plate material, an imported thermoforming processing facility is used for processing the integral demonstration table from the above-mentioned parts via the king of hot glues imported from Germany, instruments and meters are stored in the instruction case and connected with the control panel, the water feeding and discharging part employs a high-quality specially-produced hydrolock test water tank, a copper chrome-plated triple water nozzle and a ceramic chip water valve, the ventilation part is equipped with a centrifugal 5.5-KW speed-adjustable fan, and a ventilation main pipe is a UPVC engineering plastic pipe. The demonstration table prepared by using novel materials and a novel process has the advantages of a firm and reliable integral body, a beautiful shape, acid and alkali resistance, high temperature resistance, water resistance, fire resistance, no leakage at the water feeding and discharging part and no blockage in discharge of waste water and waste residues; the ventilation part can realize air-exchange more than 20 times per hour, and indoor noise is less than 55 dB; and the demonstration table can be used as modern teaching equipment for laboratories in a variety of schools.

Description

technical field [0001] The invention relates to laboratory equipment, in particular to a demonstration table for teachers in a chemical laboratory. Background technique [0002] The teachers' demonstration desks in the chemistry laboratory are mostly steel structures. There are no water supply and drainage equipment and ventilation equipment on the experimental benches. Contents of the invention [0003] The object of the present invention is to provide a demonstration platform for teachers in a chemical laboratory, which uses new materials and new techniques to make a demonstration platform with a new structure, integrates the demonstration platform table, water supply and drainage equipment, ventilation equipment, etc. There are technical defects, and the new demonstration table is resistant to acid and alkali, high temperature, non-absorbent and durable. [0004] The technical solution of the present invention is: the chemistry laboratory teacher's demonstration table ...

AI Technical Summary

Problems solved by technology

[0002] The teachers' demonstration table in the chemistry laboratory is mostly steel structure. There is no water supply and drainage equipment and ventilation equipment on the experimental table. After the experiment, it needs to be washed in the ordinary sink. There is no ventilation function.
