Description

Technical Field

[0001] This invention belongs to the technical field of ironmaking auxiliary equipment, specifically relating to a remotely controllable automatic blast furnace waterless taphole clay loading device. Background Technology

[0002] The blast furnace tapping area is where the final products, molten iron and slag, are discharged and collected during ironmaking. The tapping area is a high-temperature, dusty environment, while the mud gun is a device used to plug the taphole. Before use, the mud gun needs to be filled with mud. Blast furnaces tap iron frequently each day, requiring 30-40 pieces of mud to be filled each time, each weighing 7-10 kg. The mud filling is mostly done manually, with each piece of mud being carried and placed into the mud gun. This is labor-intensive, costly, and significantly restricts filling efficiency. Furthermore, the harsh environment poses safety hazards to workers. Currently, some tapping areas use robots for automated mud filling, but this method has extremely high requirements for incoming materials, requiring uniform specifications and neat stacking. Therefore, it necessitates increased investment in equipment before the incoming materials are processed, resulting in excessively high costs. Summary of the Invention

[0003] To address the above-mentioned problems, this invention provides a remotely controllable automatic blast furnace waterless taphole clay loading device.

[0004] To achieve the above objectives, the present invention employs the following technical solution:

[0006] Furthermore, a separator is provided at the outlet of the taphole clay to randomly push the taphole clay to the left and right, preventing the taphole clay from forming a blockage at the inlet of the conveying pipe.

[0007] Furthermore, the upper part of the conveying pipe is equipped with a sealing component to prevent flue gas from overflowing from the conveying pipe when iron is tapped.

[0008] Furthermore, the closure is a valve or a movable gate.

[0009] Furthermore, the front end of the protective sleeve is inclined parallel to the bevel, which makes it easier to push out the clay.

[0010] Furthermore, the guide slide plate is conical, and side plates are provided on both sides of the guide slide plate to prevent the blasting mud from sliding out from the sides.

[0011] Furthermore, a baffle is provided opposite to the guide slide plate, and the baffle is fixedly installed at the upper end of the conveying pipe.

[0012] Furthermore, a pressure sensor is installed below the support legs of the hopper. The pressure sensor is connected to a microcontroller and is used to collect the gravity signal of the hopper.

[0013] Furthermore, the controller also includes an alarm module connected to the wireless B module, which is used to issue an alarm when the signal value detected by the pressure sensor is lower than a set value.

[0014] Furthermore, the push rod and telescopic rod are hydraulic telescopic rods, electric telescopic rods, or pneumatic telescopic rods.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1.

[0017] 2. The present invention provides a guide slide plate below the outlet of the clay, and the lower end of the guide slide plate is connected to the upper end of the conveying pipe, which can achieve precise material feeding;

[0018] 3. The present invention has a downward slanted cut at the outlet of the clay to facilitate the downward flow of the clay and prevent the clay from being excessively squeezed and clogging the outlet.

[0019] 4. This invention allows for real-time observation of the silo's interior via a camera. Whether it's a shortage of blasting clay or an arched accumulation of blasting clay, the camera can detect these issues. Furthermore, the controller of this invention is wirelessly connected to a microcontroller, enabling remote control and simplifying the use of the controller. Attached Figure Description
