Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a gas-solid separation device for cement production. Background Art

[0002] Cement: Powdered hydraulic inorganic cementitious material. After adding water and stirring, it becomes a slurry, which can harden in the air or in water, and can firmly cement materials such as sand and stone together. In the cement production process, the chemical reaction of various raw materials will produce gas, which needs to be discharged.

[0003] Most of the existing cement production does not have a dedicated gas-solid separation device, which easily leads to residual gas in the cement, thus affecting the quality of the cement.

[0004] For example, a gas-solid separation device for cement production disclosed in Chinese patent CN212076862U includes a separation tank, a tank cover is provided on the top of the separation tank, a feed funnel connected to the inside of the separation tank is provided on the outer wall of the separation tank, a discharge pipe connected to the inside of the separation tank is provided at the bottom of the separation tank, a control valve is installed on the discharge pipe, a mounting plate with a ring-shaped structure is provided on the inner wall of the separation tank above the end of the feed funnel, a filter plate is installed on the mounting plate, an exhaust fan connected to the inside of the separation tank is provided on the tank cover, and a stirring structure is provided inside the separation tank. The gas-solid separation device for cement production extracts the gas in the cement raw material in the separation tank through the exhaust fan, and stirs it through the stirring structure to ensure that the gas in the raw material can be separated. When extracting the gas, the filter plate can effectively prevent the raw material from being extracted at the same time.
