Vertical type pressurizing roasting pot

Abstract

The invention discloses a vertical type pressurizing roasting pot. The vertical type pressurizing roasting pot comprises a high-pressure pot body, wherein a roasting liner is arranged in the pot body; a safety valve connecting tube, a direct-reading pressure gauge connecting tube, a vacuumizing connecting tube and a nitrogen pressurizing connecting tube are arranged on the pot body; the pot body consists of an upper pot body and a lower pot body which are connected together; the upper pot body and the lower pot body are provided with connecting equipment flanges which are matched with each other in a sealed manner are arranged; the two equipment flanges are connected with each other in a fastened manner through a fastening piece; a pot body support is arranged at the bottom of the lower pot body; the pot body is a water-cooling type pot body; outer jackets are respectively arranged on the outside of the upper pot body and on the outside of the lower pot body; a water-cooling interlayer is arranged between each outer jacket and the pot body; each outer jacket is provided with a pot body cooling water inlet connecting tube and a pot body cooling water outlet connecting tube; and at least two roasting electrodes are arranged on the side wall of the lower pot body. The vertical type pressurizing roasting pot has the advantages of high roasting temperature and large roasting pressure. While roasting time is shortened, roasting quality can be greatly improved, and requirements of a roasting process for producing high-end carbonaceous products are met.

Description

technical field [0001] The invention relates to a roasting equipment, in particular to a high-pressure roasting tank used for producing carbon products. Background technique [0002] High temperature and pressure roasting is required in the production process of carbon products. The roasting temperature and roasting pressure not only determine the length of roasting time, but also are related to the quality of roasted carbon products. The higher the temperature and pressure of calcination, the shorter the time required for calcination, and the finer particles and better quality of the resulting carbon product. CN 201402042Y discloses an electrode roasting tank. However, since the electrode roasting tank has no cooling structure, the tank body cannot withstand high-temperature roasting, and its roasting temperature is limited, and the pressure that the tank body can withstand is small, which cannot meet The need for pressure roasting. CN 102795620 A discloses a pressurized ...

AI Technical Summary

Problems solved by technology

However, this pressurized roasting furnace can only provide a maximum roasting pressure of 1.2MPa and a roasting temperature of 1250°C. Therefore, it cannot meet the high-temperature and high-pressure roasting environment required for the production of high-end carbon products.
