Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a device for storing and automatically adding hydrated lime. Background Art

[0002] Calcium hydroxide is an inorganic compound, commonly known as hydrated lime or slaked lime, which is a white hexagonal crystal powder. Calcium hydroxide is used in the manufacture of bleaching powder, water softener, disinfectant and insecticide, hair remover for leather making, refined sugar, and building materials, etc. In the process of cement production, when the raw material mill stops grinding, in order to control sulfur emissions to meet environmental protection requirements, substances such as hydrated lime need to be added. Hydrated lime can help reduce sulfur emissions and improve the environmental protection of the production process.

[0003] There are the following defects in an existing lime silo (authorized publication number CN219822446U): The above device pours lime from the upper feed hopper, and the lime enters the inside of the ash storage bin through the number pipe below, for storage. However, the uniform stability of the addition amount cannot be guaranteed when the hydrated lime is transported in and out of the ash storage bin for addition, and the dust pollution during the process of manually hoisting hydrated lime to add to the feed hopper increases the environmental protection risk and the labor intensity of employees. Therefore, we propose the present utility model. Content of the Utility Model

A support frame 6 is fixed to the installation frame 5. The weighing scale 3 is fixed to the top surface of the support frame 6. A PLC controller is fixed to one side of the installation frame 5. The feeding device 2, the weighing scale 3 and the pneumatic conveyor 4 are all electrically connected to the PLC controller, so as to realize the automatic control of the proportion of hydrated lime added by the central control according to the parameter changes. The weighing scale and the constant pneumatic conveying ensure the uniform and stable addition of hydrated lime. The hydrated lime storage tank 1 is increased to use bulk hydrated lime, avoiding environmental pollution and labor costs during the unloading, hoisting and adding processes of bagged hydrated lime. The installation frame 5 and the support frame 6 stably install the relevant equipment.
