Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-3, the intelligent sand filling device in this embodiment includes a hopper 1, a winch 2, a discharging pipe 3, an identification and control system 4, and a limit switch 5, where the hopper 1 contains drain sand, the winch 2 is connected to the discharging pipe 3, the drain sand in the hopper 1 can flow into the discharging pipe 3, the limit switch 5 is disposed on a steel rail on which the steel car 100 runs, and is installed at a position where the steel car 100 touches the limit switch 5 to stop, the discharging pipe 3 is just opposite to a steel outlet of the steel ladle 200, and the identification and control system 4 is in communication connection with the winch 2 and is used for identifying that the steel car 100 stops and controlling the movement of the winch 2. As can be seen from fig. 1, the hopper 1, the winch 2, the blanking pipe 3 and the identification and control system 4 are all arranged on the two-layer platform 300.

As a preferred implementation manner of this embodiment, the recognition and control system 4 includes a camera and a computer. The wheels of the steel car 100 touch the limit switch 5 to stop, the camera of the identification and control system 4 shoots a picture of the steel ladle 200 and transmits the picture back to the computer, the computer controls the winch 2 to drive the blanking pipe 3 to move downwards to the lower part of the blanking pipe 3 to be tightly attached to a steel tapping hole of the steel ladle 200, and the steel ladle 200 is filled with the drainage sand.

As a preferable implementation mode of the embodiment, the device further comprises a stirring heater 6, and the feeding port of the stirring heater 6 is connected with the discharging port of the hopper 1. The heating function of the stirring heater 6 is realized by installing a heating pipe on the outer wall of the stirrer, as shown in fig. 1, the stirring heater 6 is provided with a hot inlet pipe 61 and a cold outlet pipe 62, hot water flows into the heating pipe from the hot inlet pipe 61 to heat drainage sand in the stirrer, the drainage sand is prevented from absorbing moisture, and cold water is discharged from the cold outlet pipe 62. The identification and control system is in communication connection with the stirring heater 6.
