Description

Integrated type experiment table for chemical laboratory

Technical Field

The invention relates to the technical field of chemical experiment tables, in particular to an integrated experiment table for a chemical laboratory.

Background

At present, with the development of industry, in the work and study of chemical profession, the work related to chemical experiments is more and more, and the application of chemical experiment tables is more and more frequent, but the structure and the function of the existing chemical experiment tables are too single, so that a lot of inconvenient places are brought to the operation of chemical experiments, for example, the chemical experiment tables are not provided with a ventilation device, and the chemical experiments needing ventilation need to be carried out in a ventilation cabinet; the experiment record originally does not have the position of fixed laying yet, inconvenient record data and easy being polluted by chemical reagent in the experiment operation process, and the more chemical experiment table area of function is big moreover.

Therefore, it is necessary to develop a multifunctional chemical experiment table with small floor space, and at present, the experiment table is usually made of steel and wood or all steel. The material quality can not be classified into primary and secondary, and the service life is long. You are simply summarized with the following differences in characteristics: firstly, the material and structure steel wood experiment table: basically, the steel frame combines the all-wood cabinet body, and the support of laboratory bench is formed by epoxy spraying after pickling phosphating, and the box generally adopts melamine board fibreboard preparation. Secondly, an all-steel experiment table: all are formed by bending, spraying and assembling cold rolled steel plates. The cabinet body is generally formed by pickling and phosphating cold-rolled steel plates and then spraying epoxy resin, and is generally divided into a floor structure, a hanging box structure and a movable box structure. In addition, since different customers may have different specific uses for the test platform, the materials must be selected according to the uses during the selection, for example, the materials of the test platform specifically required for the physical experiment and the chemical experiment are different. Compared with the all-steel experiment table, the price steel-wood experiment table has certain price advantage, and the cost of the general steel-wood experiment table is lower than that of the all-steel experiment table. Thus, the selection is different for different integrated test stands.

However, the existing chemical laboratory integrated type laboratory table has the following problems: a series of chemical experiments need to be carried out on the chemical experiment table, the chemical substances have uncontrollable property more or less, the existing devices are mostly provided with simple matched placing racks and the like, great potential safety hazards exist when chemical equipment such as test tubes are stored, the prior art is not easy to solve the problems, and therefore, a chemical experiment room integrated type experiment table is urgently needed to solve the problems.
