Description

Technical Field

[0001] This application relates to the technical field of heat treatment, and more particularly, to a heat treatment device. Background Art

[0002] In the chemical industry, steel industry, paper industry, etc., there are a large number of scenarios where heat exchange is required. Existing heat treatment devices cannot meet more diverse heat exchange requirements.

[0003] For example, during the manufacturing process of lithium-ion batteries, after injecting the electrolyte or when evacuating the negative pressure after injection, the electrolyte may be pumped out and remain at the injection port, which needs to be cleaned in time to avoid electrolyte contamination. The common method is to drop dimethyl carbonate (DMC) solvent into non-woven fabric and use the non-woven fabric after dropping the solvent to wipe the injection port to achieve the purpose of removing residual electrolyte and its crystals. The solubility of electrolyte crystals at room temperature in DMC solvent is limited. If the wiping force is increased, the battery top cover may be damaged due to excessive pressure. By heating the DMC solvent, the solubility of the electrolyte in the DMC solvent can be well increased to obtain a better wiping effect. However, existing heat treatment devices cannot well meet the heating requirements for DMC solvent. Summary of the Utility Model

It solves the technical problem that the existing heat treatment device cannot meet more diverse heat exchange requirements.

[0008] In addition, since DMC is flammable, directly heating DMC with an ordinary heating device is likely to cause safety accidents. However, the heat treatment device provided in this application realizes the heat treatment of the target substance based on the medium substance.

[0055] In some alternative embodiments, the steam collection container 100 is provided with an exhaust valve 1001; the exhaust valve 1001 is disposed higher than the other end of the steam pipeline 90.

[0056] Among them, in the case where the first cavity 101 is realized by a closed cavity, the internal and external air pressures of the first cavity 101 can be balanced through the exhaust valve 1001, so as to avoid heat treatment accidents caused by excessive internal pressure in the first cavity 101, and improve the safety and reliability of the heat treatment device. And the exhaust valve 1001 is disposed higher than "the other end of the steam pipeline 90", which can prevent the target substance input through the feed pipeline from directly entering the steam pipeline, thereby avoiding the situation where the heat treatment effect is poor, and further improving the reliability of the heat treatment device.

[0057] In some alternative embodiments, the material for preparing the first container 10 includes: ceramic material, stainless steel material, or glass material.

[0058] Among them, when the first container 10 is realized by a material with a relatively high heat transfer efficiency such as ceramic material, stainless steel material, or glass material, the heat conduction efficiency between the medium substance and the target substance in the heat treatment device can be improved, and the heat treatment time can be shortened.

[0059] In some alternative embodiments, the target substance includes a dimethyl carbonate solvent; the temperature difference between the medium substance and the dimethyl carbonate solvent is greater than or equal to 5°C and less than or equal to 50°C.

[0060] Wherein, the temperature difference between the medium substance and the dimethyl carbonate solvent can be 5°C, 20°C, 50°C or other reasonable values. When the target substance is realized by the dimethyl carbonate solvent, the medium substance can be water, oil or the like.

[0061] In some alternative embodiments, the temperature of the medium substance is greater than or equal to the temperature of the dimethyl carbonate solvent; the temperature of the medium substance is greater than or equal to 20°C and less than or equal to 85°C.

[0062] Wherein, when the target substance is realized by the dimethyl carbonate solvent, the temperature of the medium substance can be 20°C, 30°C, 50°C, 85°C or other reasonable temperature values. Since the temperature of the medium substance is greater than or equal to 20°C and less than or equal to 85°C, it is possible to avoid the gasification of DMC caused by too high a medium temperature, and it is also possible to avoid the solidification of DMC caused by too low a medium temperature, that is, it is possible to ensure that DMC is in a liquid state. Since the temperature of the medium substance is greater than or equal to the temperature of DMC, the heating of DMC can be realized based on this heat treatment device. By dropping the heat-treated liquid DMC solvent onto the non-woven fabric and wiping the liquid injection port of the battery with the non-woven fabric dropped with the DMC solvent, a better electrolyte removal effect can be obtained.
