Abstract
A stage heat preserving tube furnace comprises a hearth arranged on an installation bracket. A heat preserving cover is arranged on one side of the hearth in a hinged connection mode, three cavities are formed in the hearth, the middle is a reaction zone cavity, the two ends are constant temperature zone cavities, the heating rate, the constant temperature value and the cooling rate of the constant temperature zone cavities are controlled by a temperature control module, and the cavities are divided by polyicrystal fiber materials. The hearth and the heat preserving cover are both in semi-cylindrical shapes, and a covering side of the hearth and a covering side of the heat preserving cover are provided with stainless lock catches. A sample tube penetrates through the hearth through a central hole, a sample is placed in the center of the sample tube and goes deeper to a sample layer through a thermocouple, in the reaction zone cavity of the hearth, the tube furnace conducts heating through an embedded electrical resistance heater wire, in the outside, the stainless heat preserving cover with gate holes covers the hearth in a fitting mode. The stage heat preserving tube furnace with the three different temperature independent control cavities has the advantages of being high in temperature control accuracy, small in constant temperature difference value, wide in application range, long in service life, simple in structure, convenient to machine, easy and convenient to operate and the like.
Description
Technical field
The utility model belongs to the sample analysis equipment technical field, specifically relates to a kind of tube furnace of segmentation insulation.
Background technology
Catalyst Characterization System is the common experimental device of research surface of solids feature and catalyst dynamic analysis, system is generally become by three part masters, be gas dosing and clean unit, reactor, reacting furnace and control temperature unit thereof and analysis to measure unit, wherein the structural design of reacting furnace and reactor is the key component that determines this systematic function.Be now that tube furnace exists following significantly defective by reacting furnace in technology, only have a subregion in the tube furnace burner hearth, the space is very large, just can't reach requirement to the control accuracy of temperature like this; And because the large temperature in space is high, need the time of insulation longer, power requirement to heating furnace is just higher, experimental analysis being needed only the reaction compartment that guarantees sample has enough heat insulation effects just passable, do not need very high temperature requirement for sample cell other positions, existing tube furnace is obviously unnecessary to whole sample cell heat tracing.
Summary of the invention
The utility model is mainly to solve the existing technical problem of above-mentioned prior art, and a kind of tube furnace of segmentation insulation is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of tube furnace of segmentation insulation, comprise the burner hearth that is arranged on mounting bracket, the hinged stay-warm case that is provided with of burner hearth one side, be provided with three chambers in described burner hearth, the centre is the reaction zone chamber, two ends are the flat-temperature zone chamber, and control heating rate, thermostat temperature value and rate of temperature fall by temperature control modules.
As preferably, each chamber in described burner hearth is kept apart by the polycrystal fibrous material.
As preferably, described burner hearth and stay-warm case all are semi-cylindrical, and both fastening sides are provided with the stainless steel snap close.
The utility model can be installed to the correct position of various different analytical instrument or be installed to the correct position in laboratory by mounting bracket.The utility model is separated into burner hearth the independent chamber of controlling of three different temperatures, and each chamber is kept apart by the polycrystal fibrous material, has a temperature control precision high, the thermostat temperature difference is little, and is applied widely, long service life, the characteristics such as simple in structure, processing technology facilitates, and is easy and simple to handle.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1, the tube furnace of segmentation insulation of the present utility model comprises the burner hearth 1 that is arranged on mounting bracket 5, the hinged stay-warm case 2 that is provided with of burner hearth 1 one sides, be provided with three chambers in burner hearth 1, the centre is reaction zone chamber 7, two ends are flat-temperature zone chamber 6, and control heating rate, thermostat temperature value and rate of temperature fall by temperature control modules, and each chamber is kept apart by the polycrystal fibrous material.Burner hearth 1 and stay-warm case 2 all are semi-cylindrical, and both fastening sides are provided with stainless steel snap close 4.The burner hearth separation layer can be customized to according to different requirements the straight-through endoporus that is applicable to various outer diameter sample cell 3, sample cell 3 passes burner hearth 1 by centre bore, sample is placed on the centre of sample cell and gos deep into sample layer by thermocouple, the indoor tube-type stove heats by embedded resistance heating wire in the reaction zone chamber of burner hearth, outsidely is fastened on burner hearth by the stainless steel stay-warm case with the grid holes.The utility model can be installed to the correct position of various different analytical instrument or be installed to the correct position in laboratory by mounting bracket.The utility model is separated into burner hearth the independent chamber of controlling of three different temperatures, and each chamber is kept apart by the polycrystal fibrous material, has a temperature control precision high, the thermostat temperature difference is little, and is applied widely, long service life, the characteristics such as simple in structure, processing technology facilitates, and is easy and simple to handle.
At last, should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment does.
