Chemical experiment table for students and using method

Abstract

The invention discloses a chemical experiment table for students. The chemical experiment table is characterized in that an operation table is arranged on the upper side of a table top, a control table is arranged at the upper end of the table top, an experiment cabinet is arranged on one side of the control table, a test tube rack is arranged on one side of the experiment cabinet, a weighing table is arranged on one side of the test tube rack, and an alarm is arranged on the weighing table; the weighing table and the alarm are connected with the control table through the PLC; an air cylinderis arranged in the experiment cabinet, a transparent protective cover is arranged on the lower side of the air cylinder, and a carbon dioxide storage box is arranged on one side of the air cylinder; and a lead screw III is arranged in a transmission box, a connecting plate is arranged on the lead screw III, and a cleaning device is arranged on the lower side of the connecting plate. Explosion andfire on the operation table can be rapidly removed, the safety of students is protected, the table top can be automatically cleaned, the students are prevented from taking experimental drugs out of alaboratory through the weighing table and the alarm, the safety is higher, moving is convenient, and the height of the table top can be adjusted according to the requirements of the students.

Description

technical field [0001] The invention belongs to the technical field of experiment benches, in particular to a chemical experiment bench for students. Background technique [0002] Chemical experiments are an indispensable part of the chemistry learning process, so the convenience of the chemical experiment bench directly affects the efficiency and quality of the chemical experiment. The traditional chemical experiment bench has a relatively simple structure and a relatively single function. , also caused a lot of trouble. [0003] After searching, the Chinese patent with the notification number CN105935613B is a new type of chemical experiment platform. Through the equipped experiment platform, instrument cabinet, water supply and drainage parts and grooves, it solves the problem of overturning the test tube rack during the experiment process and causing the leakage of experimental reagents. However, the device has the following deficiencies in use: 1) The safety factor of ...

[0002] Chemical experiments are an indispensable part of the chemistry learning process, so the convenience of the chemical experiment bench directly affects the efficiency and quality of the chemical experiment. The traditional chemical experiment bench has a relatively simple structure and a relatively single function. , also caused a lot of trouble

[0003] After searching, the Chinese patent with the notification number CN105935613B is a new type of chemical experiment platform. Through the equipped experiment platform, instrument cabinet, water supply and drainage parts and grooves, it solves the problem of overturning the test tube rack during the experiment process and causing the leakage of experimental reagents. However, the device has the following deficiencies in use: 1) The safety factor of the chemical experiment bench is not high. When the experiment explodes and the experimental medicine is sprayed and causes a fire, there is no cleaning equipment, which affects the safety of students; 2) After completing the experiment, the chemical When the table of the laboratory table needs to be cleaned, it is usually wiped with a rag. If there are corrosive drugs on the table, it will cause harm to the students; 3) The drugs cannot be effectively managed, and there is a risk of being smuggled out by students
