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 very complicatedly, and the heat capacity of the instrument may also change, resulting in a decrease in the accuracy of the test results and a reproducibility. Sexual deterioration

Embodiment 1

[0063] Embodiment 1: as figure 1 , image 3 , Figure 4 As shown in FIG. 5 , one or more outer tub diversion chambers 5 are provided in the outer tub cavity 23 between the inner side wall 21 and the outer side wall 22 of the outer tub. Barrel diversion chamber opening 51; the entrance of the outer barrel diversion chamber 5 is connected to the outer barrel medium inlet 201, and the outer barrel diversion cavity opening 51 is in communication with the entrance of the outer barrel diversion chamber 5. The medium can be sprayed into the outer barrel cavity 23 from the diversion cavity 51 of the outer barrel, and the medium in the outer barrel cavity 23 is pushed forward continuously by the injection medium, thereby forming self-flow agitation of the medium, and reaching each level in the outer barrel cavity 23 The temperature at the place tends to be consistent. Wherein, the diversion cavity 51 of the outer barrel can adopt a circular hole shape, a slit shape or other irregula...

Embodiment 2

[0064] Embodiment 2: as Figure 6 , Figure 8 , Figure 9 , Figure 11 , Figure 12 As shown in FIG. 13, one or more outer tub guides 53 are provided in the outer tub cavity 23 between the inner side wall 21 and the outer side wall 22 of the outer tub. Equal diameter or non-equal diameter arc-shaped spiral distribution in the outer barrel cavity 23, and form a non-closed outer barrel diversion groove 54 with the outer side wall 22 or inner side wall 21 of the outer barrel; the starting point of the outer barrel diversion body 53 is located at Below the medium inlet 201 of the outer barrel. The medium enters the outer barrel cavity 23 from the outer barrel medium inlet 201, and part of the medium will flow along the outer barrel diversion groove 54 under the diversion restriction of the outer barrel diversion body 53, and then drive other media to flow in a certain direction, forming The self-flow agitation of the medium achieves the effect that the temperature of each pla...

Abstract

The invention discloses a calorimeter with a diversion circulation temperature control device in an outer barrel, which comprises an inner barrel, an outer barrel and a barrel cover arranged on the top of the inner barrel and the outer barrel, the inner barrel is placed in the outer barrel, and the outer wall of the outer barrel is An outer barrel cavity filled with medium is formed between the inner barrel and the outer barrel, and an air interlayer is provided between the inner barrel and the outer barrel. One or more outer barrel diversion chambers for medium flow are provided in the outer barrel cavity Or the diversion body of the outer barrel, the diversion cavity of the outer barrel or the diversion body of the outer barrel and the circulation supply device form a diversion circulation temperature control device, and the circulation supply device includes a temperature control device and a driving device. The invention is a calorimeter with a diversion circulation temperature control device on the outer barrel which can keep the temperature inside the barrel cover and the outer barrel constant and create an ideal external environment for the inner barrel, thereby improving the ability of the instrument to adapt to harsh environments and improving test accuracy.

Description

technical field [0001] The invention mainly relates to a measuring instrument for measuring the calorific value of coal, oil or other exothermic substances in the coal, petrochemical or electric power industries, in particular to a calorimeter with a diversion cycle temperature control device in an outer barrel. Background technique [0002] In the prior art, the measuring instruments used to determine the calorific value of substances are generally composed of an inner barrel, an outer barrel and a barrel cover arranged on the top of the inner barrel, wherein the inner barrel is arranged in the outer barrel; when testing, the oxygen bomb of the test sample is placed on the In the inner barrel, it is connected with the ignition electrode, and the ignition is energized at the specified time, so that the sample can be fully burned. In order to ensure accurate determination of the calorific value of the substance, the temperature of the outer barrel must be kept constant. When ...
