Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a material level detection device for an electric furnace blanking pipe. Background Technique

[0002] An electric furnace is a device that converts electrical energy into heat energy and is used to heat workpieces. It has a wide range of applications in industries such as metallurgy and chemical engineering. When using an electric furnace, it is necessary to transport furnace materials along a pipeline into the interior of the electric furnace to supply the electric furnace for operation.

[0003] Currently, during the use of an electric furnace, due to the diverse physical properties of furnace materials, such as different particle sizes and degrees of looseness, some furnace materials may not be able to pass through the pipeline of the electric furnace smoothly. During the operation of the electric furnace, it is impossible to understand the situation of material falling in the pipeline and observe the blockage situation in the pipeline. This will lead to blockage of the electric furnace pipeline during material falling, and shutting down the furnace for inspection will affect the normal operation of the electric furnace and reduce production efficiency. For this reason, a material level detection device for an electric furnace blanking pipe is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a material level detection device for an electric furnace blanking pipe to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A material level detection device for an electric furnace blanking pipe, including a first mounting frame. A motor is fixedly installed on the rear side of the upper surface of the first mounting frame. The output shaft end of the motor is fixedly connected to a threaded rod. The threaded rod penetrates through the upper surface of the first mounting frame, and the threaded rod is rotatably connected to the lower surface of the first mounting frame through a bearing. A nut cylinder is threadedly connected to the outer side wall of the threaded rod. The lower surface of the nut cylinder is fixedly connected to a second mounting frame. The lower surface of the second mounting frame is fixedly connected to a first mounting block and a second mounting block respectively. A first mounting groove is opened on the right side wall of the first mounting block, and a second mounting groove is opened on the left side wall of the second mounting block. The outer side walls of the first mounting block and the second mounting block are fixedly connected with quartz glass shells. The upper surface of the quartz glass shell is fixedly connected to the lower surface of the second mounting frame. An infrared pair-detection instrument transmitting end is fixedly installed on the lower surface of the inner side wall of the first mounting groove, and an infrared pair-detection instrument receiving end is fixedly installed on the lower surface of the inner side wall of the second mounting groove.

[0006] As a further preference of this technical solution: Two mounting plates are symmetrically welded on both sides of the upper surface of the first mounting frame.

[0007] As a further preference of this technical solution: High-temperature resistant silica gel sleeves are fixedly connected to the outer side walls of the infrared pair-detection instrument transmitting end and the infrared pair-detection instrument receiving end.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, the first mounting bracket is fixed to the inner side wall of the electric furnace pipe. The motor is started to drive the threaded rod to rotate. The threaded rod drives the nut cylinder and the second mounting bracket to move downward. The second mounting bracket drives the first mounting block and the second mounting block to move downward into the pipe.

If the photosensitive transistor at the receiving end of the infrared pair detector can receive the infrared ray, it means that there is no blockage in the pipe and the furnace charge falls normally. If the receiving end of the infrared pair detector cannot receive the infrared ray, it means that the furnace charge blocks the infrared ray, indicating that there is a problem with the material falling of the electric furnace. During the operation of the electric furnace, it can be extended into the pipe to understand the material falling situation, and timely detect whether the electric furnace pipe is blocked during material falling, reducing the number of furnace shutdown inspections, not affecting the normal operation of the electric furnace, and ensuring the production efficiency.

A first mounting groove 8 is formed on the right side wall of the first mounting block 6, and a second mounting groove 9 is formed on the left side wall of the second mounting block 7. The outer side walls of the first mounting block 6 and the second mounting block 7 are both fixedly connected to a quartz glass shell 10. The upper surface of the quartz glass shell 10 is fixedly connected to the lower surface of the second mounting frame 5. An infrared pair emission detector transmitter 11 is fixedly installed on the lower surface of the inner side wall of the first mounting groove 8, and an infrared pair emission detector receiver 12 is fixedly installed on the lower surface of the inner side wall of the second mounting groove 9; fix the first mounting frame 1 on the inner side wall of the electric furnace pipe, start the motor 2 to drive the threaded rod 3 to rotate, the threaded rod 3 drives the nut cylinder 4 and the second mounting frame 5 to move downward, the second mounting frame 5 drives the first mounting block 6 and the second mounting block 7 to move downward into the pipe, use the infrared pair emission detector transmitter 11 to emit an infrared beam. If the photosensitive transistor of the infrared pair emission detector receiver 12 can receive the infrared ray, it means that there is no blockage in the pipe and the furnace charge falls normally. If the infrared pair emission detector receiver 12 cannot receive the infrared ray, it means that the furnace charge blocks the infrared ray, indicating that there is a problem with the electric furnace blanking.

[0021] In this embodiment, specifically: two mounting plates 13 are symmetrically welded on both sides of the upper surface of the first mounting frame 1; used to connect the first mounting frame 1 and the furnace body pipe.

[0022] In this embodiment, specifically: heat-resistant silicone sleeves 14 are fixedly connected to the outer side walls of the infrared pair emission detector transmitter 11 and the infrared pair emission detector receiver 12; silicone has good heat insulation performance, which can further improve the high-temperature resistance performance of the instrument.

[0023] In this embodiment, specifically: two guide cylinders 15 are fixedly connected to the lower surface of the first mounting frame 1, and two guide rods 16 are fixedly connected to the upper surface of the second mounting frame 5. The inner side wall of the guide cylinder 15 is slidably connected to the outer side wall of the guide rod 16; under the limiting action of the guide cylinder 15 and the guide rod 16, the nut cylinder 4 and the second mounting frame 5 move up and down.

The infrared beam is emitted by the emitting end 11 of the infrared pair detector. If the photosensitive transistor of the receiving end 12 of the infrared pair detector can receive the infrared ray, it means that there is no blockage in the pipe and the furnace charge falls normally. If the receiving end 12 of the infrared pair detector cannot receive the infrared ray, it means that the furnace charge blocks the infrared ray, indicating that there is a problem with the material falling of the electric furnace. The quartz glass shell 10 has good heat insulation performance, which can enable the device to work normally in a high-temperature environment. Thus, an electric furnace falling pipe material level detection device is formed.
