Description
Technical field
The present invention relates to a kind of oxidising solid test unit, especially relating to one can separate test macro and measuring system, and measuring accuracy is high, the test unit of safe and reliable modified test oxidising solid.
Background technology
Oxidizing substance is a kind of itself may not burning, but usually because releasing the material that oxygen may cause or impel other oxidation materials to burn, it belongs to the 5th class in Classification of Dangerous Chemicals.The harm of oxidizing substance is many-sided, therefore before storage and transport, must identify oxidizing substance, further to its classification, dangerous to assess it.At present, the up-to-date oxidising solid test method adopted both at home and abroad and device are responsible for " recommendation test and manual of standards about Dangerous Goods Transport " the 5th edition supplement 2 with reference to global chemical substance homogeneous classification and the labeling system problem Committee of Experts.Generally that the determinand potpourri of certain mass is placed on thermal insulation board, and thermal insulation board is directly placed in the enterprising electrical heating test that works of balance, determinand potpourri burns due to decomposes, by the mass change situation before and after the burning of balance test determinand potpourri, judge this determinand whether as oxidising solid material.But the test unit in the method cannot by test macro and measuring system separately, and the heat that during test, reaction produces can affect balance measurement, and palpus wide range when the larger weight of test macro itself defines measurement, the balance of low precision.Therefore, need design one test macro and measuring system can be separated, measuring accuracy is high, and the test unit of safe and reliable modified test oxidising solid, solves above-mentioned deficiency.
Summary of the invention
Object of the present invention is exactly provide one can by test macro and measuring system separately to overcome defect that above-mentioned prior art exists, the test unit of the modified test oxidising solid that measuring accuracy is high and safe and reliable.
Object of the present invention can be achieved through the following technical solutions: a kind of test unit of modified test oxidising solid, be provided with test macro and measuring system, it is characterized in that, described test macro and measuring system are positioned at lever system two ends, and are connected by lever system;
Described test macro comprises:
Support A: be connected with limited block;
Limited block: be arranged on support A top;
Pallet A: be arranged on lever and test one end;
Thermal insulation board: be positioned on pallet A;
Binding post: be arranged on thermal insulation board;
Resistance wire: be connected with binding post, is positioned on thermal insulation board;
Described lever system comprises:
Lever: be connected with support B;
Wire A: have two, one end connects binding post respectively, and the other end connects brush;
Wire B: have two, one end connects collector ring respectively, and the other end connects power supply:
Brush: have two, one end connects wire A respectively, and the other end contacts with collector ring:
Collector ring: have two, is arranged on support B top respectively, lever both sides, is connected with wire B;
Support B: be connected with lever;
Power supply: be connected with collector ring by wire B;
Described measuring system comprises:
Counterweight: be placed on pallet B;
Pallet B: be arranged on lever and measure one end;
Level governor: be arranged on lever and measure on the downside of one end, bottom contacts with balance on goods and services;
Balance: be arranged on below pallet B and level governor.
Solid to be detected is placed on thermal insulation board, and is heated it by power supply.
Described lever is provided with surveyor's staff, is recorded the mass change of solid to be detected by the weight of adjustment counterweight.Adopt balanced structure, offset the weight of proving installation by counterweight, the high-precision balance of small-range can be adopted thus, select flexibly, to reduce experimentation cost.
Described lever system by support B as fulcrum, by regulating the lever arm length of position adjustments test macro of support B and the lever arm length ratio of measuring system, can corresponding adjustments measurement time weightlessness and balance show increase weight between ratio.Non-bascule is utilized to improve the sensitivity of measuring system.
Described wire A is connected with collector ring by brush with between wire B, avoids the measuring error that the wire power of scratching causes.
When the present invention can avoid measuring oxidising solid danger, sample directly heats on balance, but by having set up a lever system, lever serves very important effect.First, test macro and measuring system separate by the use of lever, react the heat effects balance measurement produced when avoiding test; Secondly, due to the balanced structure of lever, counterweight can be utilized to offset the weight of test macro, when thus measuring, the high-precision balance of small-range can be used, improve the accuracy measured; Again, the lever used in device is non-bascule, the lever arm of test macro part is greater than the lever arm of measuring system part, improve sensitivity when measuring thus, and the balance by regulating the ratio of two parts lever arm length to select different range and precision: last, wire is connected with collector ring by the brush at balance pivot place, avoids the measuring error that the wire power of scratching causes.Compared with prior art, following advantage is specifically comprised:
(1) simple structure, cost is lower;
(2) test macro and measuring system are separated, the heat effects balance measurement that when avoiding testing, reaction produces;
(3) small-range, high-precision balance can be selected, select various;
(4) non-bascule improves the sensitivity of measuring;
(5) measuring error that the wire power of scratching causes is avoided in the use of brush and collector ring.
