Description

Technical Field

[0001] This utility model relates to the field of mud gun control technology, specifically a remote mud gun control device for ironmaking blast furnaces. Background Technology

[0002] Hydraulic mud guns, also known as blast furnace mud guns, blast furnace mud guns, ironmaking blast furnace mud bubbles, and blast furnace hydraulic mud guns, play a very important role in the metallurgical industry. They can accurately block the taphole after tapping iron, ensuring the smooth operation of the next cycle of blast furnace operations. Compared with mechanical mud guns, the main advantages of hydraulic mud guns are low price, convenient operation, high efficiency, stable and reliable performance, smooth operation, simple structure, and light weight. They are currently the most ideal furnace front equipment for large, medium and small ironmaking plants.

[0003] However, the angle of the control room and the smoke and noise during tapping are also troublesome. To address this, a remote mud gun control device for blast furnaces is provided (see patent number: 202210726581.1). This device includes an industrial remote controller, a hydraulic station, a PLC, an industrial display, and relays. The industrial remote controller transmits control signals to the hydraulic station, and the PLC then sends these signals to the corresponding relays to control the motor start contactors of the hydraulic station, thereby controlling the mud gun and the tapping machine. The industrial display is installed on the electrical cabinet of the hydraulic station, providing real-time feedback on the hydraulic station's operating signals. This device reduces the operational risks for employees, improves their field of vision, reduces operational hazards, and increases employee work efficiency.

[0004] However, some remote mud guns for blast furnaces on the market are still manually controlled, which results in a lack of standard data references and high arbitrariness. This leads to problems such as repetitive operations in processes such as mud making, drilling, and hooking. In severe cases, this not only increases labor intensity and wastes mud, but also frequently damages equipment. Utility Model Content

[0005] The purpose of this utility model is to address the problem that some remote mud guns for blast furnaces on the market are still manually controlled, resulting in a lack of standard data references, high arbitrariness, and repetitive operations in processes such as mud making, drilling, and hooking. In severe cases, this not only increases labor intensity and wastes mud, but also frequently damages equipment. The present invention provides a remote mud gun control device for blast furnaces.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a remote mud gun control device for ironmaking blast furnaces, comprising:

[0007] The main body of the device is used to support the remote mud gun control components of the blast furnace.

[0008] The adjustment component is located in the middle of the device body;

[0009] The adjustment assembly includes a housing, a gear located in the middle of the housing, movable rods on both sides of the gear, a connecting rod at the end of each set of movable rods away from the gear, a baffle between one side of each set of connecting rods, an asynchronous motor at one end of the gear, a turn wheel at the end of the gear away from the asynchronous motor, and movable grooves on the outer sides of each set of connecting rods.

[0010] As a further embodiment of this utility model: the device body includes a conveying pipe, and a signal transmitter is provided at the top of the middle position on one side of the conveying pipe.

[0011] As a further improvement of this utility model: a support frame is provided at the top of one end of the conveying pipe, and a heat resistance monitor is provided at the top of the support frame.

[0012] As a further improvement of this utility model, the movable rod is connected to a gear by meshing teeth.

[0013] As a further improvement of this utility model, both sets of baffles are movably connected to the outer shell via connecting rods, movable grooves, and moving rods.

[0014] As a further improvement of this utility model, multiple sets of cutting teeth are provided at the connection points of the two sets of baffles.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When mud sealing is required, the signal transmitter receives a signal to start the asynchronous motor. The asynchronous motor drives the gear to rotate, and the moving rod is connected to the gear through a locking tooth. The moving rod moves outward, driving the connecting rod to move outward, causing the two sets of baffles to move outward, and then mud sealing is performed. At the same time, the sealing is observed through a heat resistance monitor. After sealing is completed, the asynchronous motor rotates in reverse, and the two sets of baffles also move inward. The sealing mud is cut by the cutting teeth. It can also be operated manually by turning the wheel. This device is convenient to use and simple to operate. The set adjustment components can automatically realize the mud sealing operation, saving the tedious manual operation and making it highly practical. Attached Figure Description
