Description

Technical Field

[0001] The utility model relates to the technical field of quicklime production, and particularly relates to a conveyor belt mixing mechanism. Background Art

[0002] The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are widely used as raw materials for building materials and industry. Limestone can be directly processed into stones and burned into quicklime, that is, CaO. As an industrial raw material, it can be used to produce hydrated lime, gypsum powder, cement and other industrial products. In the production of calcium oxide, generally, limestone stones need to be mixed with coal blocks as fuel and then poured into a kiln together.

[0003] In order to ensure the production stability of calcium oxide, quantitative weighing is required before the limestone stones are fed, which is convenient for the quantitative addition of coal materials to ensure the firing effect of the kiln. The existing metering hoppers are generally tipping hoppers, which can only be emptied once after weighing, resulting in the coal materials being weighed once and then added manually, and a mixer is needed to mix the materials again. Only after the stones and coal materials are evenly mixed can they be put into the kiln for firing. The process is troublesome, the feeding efficiency is low, it is not suitable for automated production, and there is room for further improvement. Content of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a conveyor belt mixing mechanism to solve the above problems.

The lowest end of the lifting support is provided with a stone hopper base. Above the inner side of the stone hopper base, there is a stone weighing metering hopper. In the middle of one side of the lifting support, there is a coal hopper base. Above the inner side of the coal hopper base, there is a coal weighing metering hopper. At the bottom discharge port of the stone weighing metering hopper, there is a vibrating discharge hopper suspended. The bottom of the coal weighing metering hopper is fixedly connected with a suspension bracket. At the bottom of the suspension bracket, there is a coal conveyor belt. Above the lifting support, there is a mixing conveyor belt fixedly connected. On both sides above the lifting support, there are a plurality of side plate supports fixedly connected. On both sides above the mixing conveyor belt of the lifting support, there are conveyor belt side plates fixedly connected through the side plate supports. At the inner sides of one ends of the two conveyor belt side plates close to the vibrating discharge hopper, there are discharge shovels.

[0006] According to the conveyor belt mixing mechanism described above, both the vibrating discharge hopper and the coal conveyor belt are arranged above the mixing conveyor belt.

[0007] According to the described conveyor belt mixing mechanism, the overall shape of the discharge shovel corresponds to the shape of the discharge port of the vibrating discharge hopper, and one end of the discharge shovel far from the conveyor belt side plate is arranged inside the discharge port of the vibrating discharge hopper.

[0008] According to the described conveyor belt mixing mechanism, both sides of the discharge shovel far from the vibrating discharge hopper are respectively rotatably connected to the corresponding conveyor belt side plates through bolts.

[0009] According to the described conveyor belt mixing mechanism, both the coal conveyor belt and the mixing conveyor belt are electric conveyor belts.
