Problems solved by technology

Due to the different nature of endothermic and exothermic, and the degree of intensity is uncertain each time, the process is long. During this process, the temperature of the outer barrel changes extremely complicatedly, and the heat capacity of the instrument may also vary greatly, resulting in a decrease in the accuracy of the test results. poor reproducibility

Embodiment 1

[0050] Embodiment 1: As shown in FIG. 1, one or more cover wave wheels 31 are provided in the barrel cover 3, and the cover wave wheels 31 are connected to the cover driving device 32. The cover driving device 32 includes a cover motor 321 and a coupling 322. The output shaft of the cover motor 321 is connected to the cover wave wheel 31 through a coupling 322. The lid motor 321 drives the lid impulse wheel 31 to rotate through the coupling 322, which has a stirring effect on the medium in the lid 3, ensuring that the temperature in the lid 3 is basically the same, and the temperature will not appear at different positions. Different phenomena improve the stability of the ambient temperature of the inner barrel 1, thereby improving the measurement accuracy of the calorimeter, and can obtain more accurate measurement values. In this embodiment, one or more outer barrel pulsators 5 are further provided at the bottom of the outer barrel cavity 23, and the outer barrel pulsators 5 are...

Embodiment 2

[0051] Embodiment 2: As shown in FIG. 2, FIG. 3 and FIG. 4, one or more cover wave wheels 31 are provided in the barrel cover 3, and the cover wave wheels 31 are connected to the cover driving device 32. A cover blade 33 is installed above the cover wave wheel 31, and the cover blade 33 and the cover wave wheel 31 form a certain angle α. In this embodiment, the α is 90 degrees, that is, the cover wave wheel 31 and the cover blade 33 are perpendicular to each other. . α satisfies the following relationship: D>l+2Lcosα; where D is the diameter of the barrel cover 3, and l is the horizontal length of the cover wave wheel 31. At the same time, in order to satisfy the work of the cover wave wheel 31 for different cover heights and water depths, when the ratio of the height value of the cover 3 to the vertical height value of the cover blade 33 is 2-6, the cover wave wheel 31 and the cover blade 33 The combination can fully and uniformly stir all the media in the lid 3 to achieve the be...

Embodiment 3

[0052]Embodiment 3: As shown in Fig. 5, one or more lid stirrers 34 are provided in the lid 3, and the lid stirrers 34 are equipped with magnets, one end is N pole and one end is S pole. Above the lid stirrer 34, a lid driving device 32 is installed outside the top plate of the barrel lid 3. The cover driving device 32 includes a cover motor 321 and a cover rotation shaft 326. The cover rotation shaft 326 is connected to the output shaft of the cover motor 321, and a cover magnet 327 is installed on the cover rotation shaft 326, one end of which is N pole and one end is S pole. According to the inherent characteristics of magnets of opposite sexes attracting and same sex repulsive, the N pole and S pole on the cover stirrer 34 are always in phase with the S pole and N pole of the cover magnet 327 respectively, keeping the same. The lid motor 321 drives the lid magnet 327 to rotate through the lid rotating shaft 326, and then drives the lid stirrer 34 to rotate through the attracti...

Abstract

The invention discloses a calorimeter of barrel head with mixing cycling temperature control device, comprising inner barrel, outer barrel and barrel head set at tops of inner barrel and outer barrel. The inner barrel is set in the outer barrel and cavity of outer barrel is formed between outer side wall and inner wall of outer barrel. Air interlayer is set between the inner barrel and the outer barrel. One or more than one head mixing devices for medium mixing and cycling are set in said barrel head. The head mixing device and the cycling supply device form the mixing cycling temperature device. The cycling supply device comprises temperature control device and driving device. The invention is the calorimeter which can maintain uniform temperature of barrel head and outer barrel and creates an ideal outer circumstance for inner barrel so as to improve the capability that instrument adapts bad circumstance and improve testing accuracy.

Description

Technical field [0001] The invention mainly relates to a measuring instrument used in the coal, petrochemical or electric power industries to measure the calorific value of coal, oil or other heat-generating substances, and specifically refers to a calorimeter with a stirring and circulating temperature control device on the lid. Background technique [0002] In the prior art, measuring instruments used to determine the calorific value of a substance generally consist of an inner barrel, an outer barrel, and a lid set on the top of the inner barrel. The inner barrel is set in the outer barrel; when testing, the oxygen bomb of the test sample is placed in the The inner barrel is connected with the ignition electrode, and it is energized and ignited at the specified time to allow the sample to fully burn. In order to ensure accurate determination of the calorific value of the substance, the outer barrel must be kept constant. When the ambient temperature remains constant and the ou...
