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. In this process, even if the temperature reading of the outer barrel is the same, the heat capacity of the instrument may vary greatly, resulting in a decrease in the accuracy of the test results and poor reproducibility. become worse

Embodiment 1

[0055] Embodiment 1: as figure 1 and figure 2 As shown, the lid partition 31 in this embodiment is radially arranged in the bucket lid 3 along the centerline of the bucket lid 3, and divides the bucket lid 3 into two or more lid cavities 301, following the flow of the medium direction, a first middle partition 304 is provided between the first cover cavity 301 and the last cover cavity 301, and the first middle partition 304 completely separates the medium inlet part and the medium outlet part. Part of the cover dividing plate 31 links to each other with the top of the bung 3, and another part of the cover dividing plate 31 links to each other with the bottom of the bung 3, so there is a gap between the cover dividing plate 31 and the top inner wall or the bottom end inner wall of the bung 3. The gaps that allow the passage of the medium make the lid cavities 301 communicate with each other in turn. The medium can flow from the first cover cavity 301 through each cover cavi...

Embodiment 2

[0056] Embodiment 2: as Figure 4 and Figure 5 As shown, the lid partition 31 in this embodiment is radially arranged in the bucket lid 3 along the centerline of the bucket lid 3, and divides the bucket lid 3 into two or more lid cavities 301, following the flow of the medium direction, a first middle partition 304 is provided between the first cover cavity 301 and the last cover cavity 301 , and the first middle partition 304 completely separates the medium inlet and the medium outlet. Wherein, there is a gap that allows medium to pass between part of the cover partition 31 and the inner side wall of the bucket cover 3, and there is a gap that allows the medium to pass between another part of the cover partition 31 and the adjacent cover partition 31, so that The lid cavities 301 communicate with each other in sequence. The medium can flow from the first cover cavity 301 through each cover cavity 301 to the last cover cavity 301 in turn. During the flow process, since the ...

Embodiment 3

[0057] Embodiment 3: as Figure 7 and Figure 8 As shown, in this embodiment, the cover partition 31 is arranged in parallel in the bucket cover 3, and the bucket cover 3 is divided into two or more than two cover cavities 301, wherein part of the cover partition 31 is connected to the top of the bucket cover 3, And another part of the lid partition 31 is connected to the bottom of the bung 3, so there is a gap that allows the medium to pass between the lid partition 31 and the top inner wall or the bottom inner wall of the bung 3, so that each lid cavity 301 interconnected in turn. The medium can flow from the first cover cavity 301 through each cover cavity 301 to the last cover cavity 301 in turn. During the flow process, since the communication positions of each cover cavity 301 are inconsistent, the medium passes through each cover cavity When the body 301 is different in speed, direction of movement, and the size of the passing volume, a self-flow agitation will be gen...

Abstract

The invention discloses a calorimeter with a closed cavity circulating temperature-control device on a drum cover. The calorimeter comprises an inner drum, an outer drum and the drum cover which is arranged between the inner drum and the outer drum, wherein the inner drum is placed in the outer drum, an outer drum cavity filled with medium is formed between the outside wall and the inside wall of the outer drum, an air interlayer is arranged between the inner drum and the outer drum, one or more pieces of drum cover partition boards are arranged in the drum cover to partition the drum cover into two or more than two cover cavities, the two or more than two cover cavities form a closed cavity circulating temperature-control device together with a circulating supply device, and the circulating supply device comprises a temperature-control device and a drive device. The calorimeter can keep the temperature consistency in the outer drum and the drum cover, and create an ideal outer environment for the inner drum so as to improve the capability of the calorimeter to adapt to harsh environment, shorten the testing time and improve the testing accuracy.

Description

[0001] This application is a divisional application [0002] The filing date of the original application is: March 29, 2006 [0003] The application number is: 200610031416.5 [0004] The name of the invention is: calorimeter with a closed-circuit cavity circulation temperature control device on the lid technical field [0005] 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 closed-circuit cavity circulation temperature control device on the barrel cover. Background technique [0006] 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 sam...
