Description
Technical field:
The present invention relates to the heating-value determination instrument of coal in coal, petrochemical complex or the power industry, oil or other pyrogen, be specifically related to test the improvement of bucket.
Background technology:
In the prior art field, the basic structure of measuring the instrument of material thermal value all has constant temperature bucket, interior bucket, inner barrelhead, cover inner barrelhead on the bucket wherein and place the constant temperature bucket, adopt working methods such as heat-insulating, thermostatic type, self-action, dry type, the temperature of constant temperature bucket and inner barrelhead depends primarily on environment temperature.Under the constant situation of environment temperature, the thermal capacity of measuring system is stable, can guarantee to measure exactly the thermal value of material; But because that the temperature of instrument environment of living in is difficult to is constant, and changes big, non-linear and be difficult to prediction, cause the constant temperature barrel temperature to change greatly, thereby cause that measurement system thermal capacity changes, consequently be difficult to accurately measure the thermal value of material.At present, a bucket ambient temperature is in steady state value in how guaranteeing, thereby the thermal value of working sample exactly is the problem of this field scientific research personnel further investigation always, the applicant had once also carried out many-sided improvement to this, but the error of some measuring accuracy is more or less always arranged.
Summary of the invention:
Technical matters to be solved by this invention is that the bucket ambient temperature is in a steady state value in how further guaranteeing, thereby improves measuring accuracy.
Realize by following technical scheme on the technical matters of the present invention.It comprises the inner barrelhead that bucket within the oxygen bomb is housed, is coated on the outer constant temperature bucket of interior bucket and places interior bucket end face and be used to seal, refrigeration all is housed in bucket and the constant temperature bucket in described or heats medium, be provided with system cooling and heating machine and temperature sensor in the constant temperature bucket, the outer temperature regulating device of temperature sensor and constant temperature bucket links to each other, it is characterized in that offering on the described inner barrelhead is communicated with the constant temperature bucket and can with interior barrel and constant temperature bucket in freeze or heat medium and carry out chamber within the heat interchange.Be to guarantee the carrying out of cyclic process, on inner barrelhead, be respectively equipped with the water inlet pipe and the rising pipe that are communicated with inner chamber and join with the constant temperature bucket; Be connected through the hinge between inner barrelhead and the constant temperature bucket, lock with dead bolt.
The present invention compared with prior art, a bucket ambient temperature be in a steady state value in can be further guaranteeing from structure, is further perfect to the application's technology formerly, thereby improves measuring accuracy.
Description of drawings:
Fig. 1 is the present invention's structure embodiment.
Among the figure:
The 1-oxygen bomb; Bucket in the 2-; The 3-inner barrelhead;
4-constant temperature bucket; 5-makes cooling and heating machine; The 6-temperature sensor;
The 7-temperature regulating device; The 8-ebullator; The 9-sealing gasket;

The 13-hinge; The 14-dead bolt.
Embodiment:
The present invention is the improvement of being done on existing calorimeter for measuring temp, mainly is the improvement to inner barrelhead.As shown in Figure 1, the present invention includes oxygen bomb 1, interior bucket 2, inner barrelhead 3 and constant temperature bucket 4 are housed, oxygen bomb 1 is loaded in the interior bucket 2, and interior bucket 2 is loaded in the constant temperature bucket 4, in bucket 2 end faces establish inner barrelhead 3, when inner barrelhead 3 is placed on the bucket 2 time, make the airtight space of formation in the whole bucket one.Refrigeration all is housed in interior bucket 2 and constant temperature bucket 4 or heats medium, be provided with system cooling and heating machine 5 and temperature sensor 6 in the constant temperature bucket 4, system cooling and heating machine 5 can freeze by the temperature of setting according to the needs of test environment temperature or heat, system cooling and heating machine 5 is connected with temperature regulating device 7 with temperature sensor 6, measure the interior actual temperature of bucket by temperature sensor 6, signal is passed to constant temperature bucket 4 temperature regulating device 7 outward, make its power switch circuit that triggers system cooling and heating machine 5, constant on the artificial value of setting by the work of ebullator 8 in order to residing environment temperature around the bucket 2 in the accurate control.Because the mensuration that heats the thermal value of material is subjected to the influence of environment temperature, bucket 2 ambient temperatures kept constant in accurate mensuration must make, though and formerly technology has guaranteed the unification of interior bucket 2 bottoms and surrounding enviroment temperature, but for interior bucket 2 upper areas, though a system cooling and heating machine that is connected with temperature regulating device 7 also can be set on inner barrelhead 3, but be difficult in the unification that reaches immediately in the very short time with constant temperature bucket 4 temperature, can bring the transient error of measurement sometimes unavoidably.For overcome this defective as far as possible, design proposal of the present invention is to offer an inner chamber 10 on inner barrelhead 3, it can be communicated with constant temperature bucket 4 and can or heat medium with refrigeration in interior bucket 2 and the constant temperature bucket 4 carries out heat interchange, promptly by in test process, making in the constant temperature bucket 4 refrigeration or heating that inner chamber 10 media constantly exchange on medium and the inner barrelhead 3, unification with bucket 2 top environment temperatures and other position in guaranteeing, eliminate measuring error, improve the accuracy of test.The present invention at concrete embodiment as shown in Figure 1, this inner chamber 10 to offer position and constant temperature bucket 4 sizes corresponding, bucket 2 forms an airtight cyclic space respectively with inner chamber 10 in making, barrel 2 ambient temperatures was constant in this mode can guarantee effectively.
As shown in the figure, the concrete loop structure of the present invention is to connect a water inlet pipe 11 and rising pipe 12 on inner barrelhead 3 respectively, this water inlet pipe 11 and rising pipe 12 can be flexible pipe, the one end all joins with inner chamber 10, the other end is communicated with constant temperature bucket 4, in in bucket 2 or the constant temperature bucket 4 refrigeration or heat medium and can finish each other heat interchange by two pipes, make in the constant temperature bucket 4 that temperature reach unified in the temperature and inner chamber 10, thereby realize purpose of the present invention.
Can be connected by hinge 13 between bung 3 and the constant temperature bucket 4 within the present invention, surface of contact can be with sealing gasket 9 sealings, to avoid the ambient temperature influence, covers when tight with dead bolt 14 lockings, prevents to open arbitrarily in the test process, guarantees the accuracy of test process.
