Coal-adding system with screening function

Abstract

The invention discloses a coal feeding system with a screening function, which comprises a coal feeding bin, a plug valve is arranged at the outlet of the coal feeding bin, a conveyor belt device is arranged under the coal feeding bin, and a conveyor belt device is arranged at the end of the coal feeding bin. Drying furnace, the middle part of the conveyor belt device is provided with a stopper device, the stopper device includes a support frame connected to the conveyor belt device, a baffle is hingedly connected to the support frame, and the upper part of the support frame is connected to a The installation plate, the middle part of the installation plate is connected with a cylinder, and the cylinder above the support frame is also connected with a cylinder that can push out the baffle plate; a screening device is also provided below the coal bunker, and the screening device includes a fixed frame. A vibration motor is arranged on the fixed frame, and a fixed frame is also arranged on the fixed frame, and a coal screen is detachably arranged on the fixed frame. The system has a simple structure, and can evenly and quickly add coal into the drying furnace, and the combustion is fully uniform, and at the same time, large coal blocks can be screened out.

Description

technical field [0001] The invention belongs to the field of chemical production, and in particular relates to a coal feeding system with screening function. Background technique [0002] In the process of strontium carbonate production, the drying furnace is often used equipment. When using the drying furnace, it is necessary to continuously add coal to the drying furnace. If the method of adding carbon manually is time-consuming and laborious, And the coal after adding is not fully burned, a large amount of energy will be wasted, and it is not conducive to energy saving and environmental protection. Contents of the invention [0003] The invention proposes a coal feeding system with a screening function. The system has a simple structure, can uniformly and quickly feed coal into a drying furnace, and burns fully and uniformly. [0004] The technical solution of the present invention is achieved in the following way: a coal feeding system with a screening function, compr...
