Abstract
The utility model relates to a quartz spring thermobalance, which is composed of a balance protection gas inlet, a quartz spring, a quartz casing, an iron core, a differential transformer, a reaction gas inlet, a specimen disc, a heater, thermocouple temperature measuring hole and a produced gas outlet. The utility model with the advantages of simple structure and low cost can be used in the high-temperature atmosphere (1300 DEG) and corrosive atmosphere.
Description
The utility model relates to a kind of quartz spring thermobalance.
Thermobalance is the device of consecutive weighings sample mass when heating or cooling samples, and its history has only short decades.Commercially available thermobalance is weighed mainly by temperature control, and record and atmosphere etc. are partly formed.Can be divided into the balance of beam balance, pull spring supporting, balance, volute spring balance, the arm sky equality of suspender belt supporting by the form of weighing.Beam balance is the balance that utilizes the bascule principle for balance.In order to make it can be used for corrosive atmosphere, strict to its material, thereby price is expensive, processing difficulties limits its application.The balance of pull spring supporting is to adopt the pull spring bearing cross beam, and with the beam balance that the electromagnetism resetting means combines, its shortcoming is the pull spring fragility, and is easily broken, and range of weighing is little.The balance of suspender belt supporting is the beam balance that cutter supports in doing with suspender belt, and its shortcoming is the sensitivity that the setting height(from bottom) of the width of suspender belt and suspender belt has a strong impact on balance.The gentle arm balance in volute spring sky is that to adopt tinsel be that the spring of material is the balance of weighing mode, and its main defective is to operate under the atmosphere of corrosivity species such as sulfur-bearing, nitrogen, chlorine.
The purpose of this utility model is to develop a kind of simple in structure, low price and the quartz spring thermobalance that can use under aggressive atmosphere.
The purpose of this utility model is achieved in that
Quartz spring formula thermobalance mainly is made up of quartz spring, crystal reaction tube, the system that weighs, temperature control system, atmosphere system.Spring is accurately proofreaied and correct through counterweight before use.Its principle of work is iron core and the platter that spring plays differential transformer, and heating furnace is in the protection tube outside, and spring generation linear extendible when sample weight changes causes differential transformer to produce with the proportional signal of displacement and delivers to registering instrument.Therefore the output signal of differential transformer can be shown with weight change.And specimen temperature detects and record with the thermocouple near sample.Working temperature can reach about 1300 ℃.This device can be used for the weight change METHOD FOR CONTINUOUS DETERMINATION under (except the HF gas) condition in certain vacuum degree and the various atmosphere.
Embodiment accompanying drawings of the present utility model is as follows:
Fig. 1 is the structural representation of the utility model quartz spring thermobalance.
As shown in the figure, 1 is the indifferent gas import, and 2 is quartz spring, and 3 is quartz container, and 4 is unshakable in one's determination, and 5 is differential transformer, and 6 are the reaction gas inlet, and 7 is sample disc, and 8 is well heater, and 9 is thermoelectric corner thermometer hole, and 10 are the maker outlet.
The sample that in sample disc 7, adds known weight, feed blanket gas from indifferent gas inlet 1, well heater 8 heats, observe temperature variation with the thermopair in the thermocouple hole 9, reach temperature required after, feed reaction gas from reaction gas inlet 6, the signal of differential transformer 5 outputs is represented with weight and is got off with the register continuous recording; Export 10 sample analysis from generating gas, the observation reaction result.
Compare with commercially available thermobalance, the utility model has the advantages that:
1. simple in structure, easy to operate, low price.
2. because the quartz of employing corrosion-and high-temp-resistant is made spring and shell, so can be at height Reach under 1300 ℃ the temperature and operate in any atmosphere except HF gas.
3. can directly observe the variation that sample changes and remember continuously sample weight.
4. it is convenient that reaction generates the gas sampling.
