[0026] In the embodiment, as the preferred technical scheme, the driving mechanism comprises a motor 10 fixedly arranged at the upper end of the gantry 6, an eccentric cam 11 fixedly arranged on the driving shaft of the motor 10, a baffle 12 fixedly arranged at the upper end of the guide rod 7, and a spring 13 sleeved on the guide rod 7 and located between the gantry 6 and the baffle 12, and the eccentric cam 11 is in contact with the baffle 12.
[0027] In the embodiment, as the preferred technical scheme, the pushing mechanism comprises an electric push rod 14 fixedly arranged on the side wall of the hopper 1, a push plate 15 fixedly arranged at the piston end of the electric push rod 14 and extending into the hopper 1, and a slag discharge port 18 arranged on the side of the hopper 1 and corresponding to the position of the screening net 2.
[0028] The working principle of the vibrating screening device of the lime kiln feeding hopper is as follows: when the limestone raw materials enter the hopper 1 from the feeding port 4 and are located above the sieve plate 9, the motor 10 is started to drive the eccentric cam 11 to rotate. The eccentric cam 11 is in contact with the baffle 12 at the upper end of the guide rod 7, and due to the elastic effect of the spring 13, the rotation of the eccentric cam 11 is converted into the up-down vibrating movement of the guide rod 7, so that the vibrating plate 8 vibrates the limestone raw materials on the sieve plate 9 to break the agglomerated raw materials. At the same time, the vibrating motor 3 is started to drive the screening net 2 to vibrate, so that the raw materials preliminarily treated by the sieve plate 9 are further screened, and the small-particle raw materials fall from the discharging port 5 through the screening net 2. When it is necessary to clean the residues on the screening net, the electric push rod 14 is started to push the push plate 15 to move along the screening net 2, so that the residues on the screening net 2 are pushed out from the slag discharge port 18, and the screening net 2 is kept clean.
[0029] The working process of the vibrating screening device of the lime kiln feeding hopper is as follows:
[0030] 1. Feeding preparation: before the equipment is started, it is checked whether all components are normal, and the motor 10, the vibrating motor 3 and the electric push rod 14 are in the initial state.
[0031] 2. Feeding stage: the limestone raw materials enter the hopper 1 from the feeding port 4 and fall on the sieve plate 9, and the uniformly distributed discharging holes 16 on the sieve plate 9 can preliminarily make part of the small-particle raw materials fall. At this time, the protrusions 17 on the lower end surface of the vibrating plate 8 corresponding to each discharging hole 16 help to further break the raw materials.
[0032] 3. Vibrating and screening: the motor 10 drives the eccentric cam 11 to rotate, so that the guide rod 7 moves up and down on the gantry 6, and the vibrating plate 8 continuously vibrates the raw materials on the sieve plate 9 to break the agglomerated raw materials. The vibrating motor 3 drives the screening net 2 to vibrate, so that the raw materials passing through the sieve plate 9 are further screened on the screening net 2, and the qualified small particles fall through the screening net 2 to the discharging port 5.
[0033] 4. Cleaning stage: when the screen 2 needs to be cleaned during the screening process, first stop the vibration motor, then start the electric push rod 14, the piston end pushes the push plate 15 to move along the screen 2, pushes the residues on the screen 2 to the residue discharge port 18 to discharge, prevents the screen 2 from being blocked, and ensures that the screening work continues to be effectively carried out.
