The utility model comprises the following steps:
the utility model aims to provide a feeding device of a limestone preheater, which has a simple structure and saves electric energy.
The utility model is implemented by the following technical scheme: the patent aims to provide a feeding device of a limestone preheater, which comprises a shell, wherein a rotating shaft is rotatably arranged on the inner wall of the shell, and a plurality of arc-shaped blades are fixed on the side wall of the rotating shaft along the circumferential direction of the rotating shaft; the inner cambered surface of the arc-shaped blade is connected with a limestone material.
Further, the upper surface and the lower surface of the shell are respectively provided with a feed inlet and a discharge outlet, and the feed inlet and the discharge outlet are arranged in a staggered manner.
Further, one end of the rotating shaft penetrates through the shell and is in transmission connection with the driving motor, a rotating speed sensor is arranged on the driving motor, a signal output end of the rotating speed sensor is connected with a signal input end of the controller through a signal, and a signal output end of the controller is connected with a signal input end of the driving motor through a signal.
The utility model has the advantages that: 1. the utility model has simple structure and easy realization, the inner cambered surface of the arc-shaped blade is connected with the limestone material, the rotating shaft rotates under the action of the weight and impact force of the limestone material, the stable and uniform discharging of the material is ensured, and meanwhile, a motor driver is not required to be used for rotation, so that the electric energy is saved, and the production cost is reduced; 2. the feeding hole and the discharging hole on the shell are arranged in a staggered manner, so that high-temperature gas can be effectively prevented from flowing to the elevator, the normal operation of the elevator is ensured, and fire accidents are prevented; 3. the rotating speed sensor detects the rotating speed of the driving motor driven by the rotating shaft during rotation, and sends a signal to the controller, when the rotating speed reaches a set lower limit value, the controller controls the driving motor to start, drives the rotating shaft to rotate, and prevents blocking caused by clamping materials between the arc-shaped blades and the shell, so that the operation of equipment is influenced; when the rotating speed reaches the set upper limit value, the controller controls the driving motor to stop, and the rotating shaft is driven to rotate by the weight and impact force of the limestone material, so that the normal operation of the equipment is ensured, and the economic benefit of enterprises is improved.
