Description

Technical Field

[0001] The utility model relates to the technical field of ferroalloy submerged arc furnaces, and particularly relates to a PLC automatic control device for a ferroalloy submerged arc furnace. Background Art

[0002] A ferroalloy submerged arc furnace is used for reducing and smelting raw materials such as ores, carbonaceous reducing agents and solvents, and mainly produces ferroalloys such as ferrosilicon and ferromanganese. It is an important industrial raw material in the metallurgical industry and chemical raw materials such as calcium carbide. When working, a PLC automatic control device is required to control the heat of its furnace body and the like.

[0003] According to the design of the existing PLC automatic control device for a ferroalloy submerged arc furnace, when installing the control module, it is not convenient to adjust the placement space according to the size of the control module, resulting in insufficient applicability; after the PLC automatic control device of the ferroalloy submerged arc furnace has been used for a long time, smoke will be generated due to overheating. If not handled in time, safety accidents will occur; at the same time, there is no protection device for the display screen, resulting in dust accumulation after a period of use, and the control buttons will be inconvenient to operate after long-term dust accumulation.

[0004] Therefore, it is necessary to design a new PLC automatic control device for a ferroalloy submerged arc furnace to solve the above existing technical problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a PLC automatic control device for a ferroalloy submerged arc furnace with reasonable structural design, low processing and manufacturing cost, convenient operation, safety and reliability. When a danger occurs, it can process the inside in time and has a long service life.

[0006] A PLC automatic control device for a ferroalloy submerged arc furnace of the utility model includes a control cabinet and a cabinet door. The control cabinet and the cabinet door are movably hinged. A display module is fixedly installed on the surface of the side wall of the cabinet door. A display screen is fixedly installed on the surface of the other side wall of the cabinet door. Control buttons are arranged below the display screen. On both sides of the inner wall of the control cabinet, first fixing seats are respectively fixedly installed. A first placement groove is arranged on the side wall surface of the first fixing seat. A placement plate is arranged in the first placement groove and can slide along the first placement groove. A fixing plate is fixedly installed on the side wall surface of the placement plate.

[0007] According to the size of the display module, the placement plate can be placed in the corresponding first placement groove. Push the placement plate to one end. Since the first placement grooves are equally spaced, the distance between the placement plates can be adjusted according to the height of the display module. The placement plate is mainly used to place internal components in the control cabinet, such as relays, controllers, etc.

[0008] A positioning block is fixedly installed on the inner wall surface of the control cabinet. A clamping groove is arranged on the side wall surface of the placement plate. The positioning block is clamped with the clamping groove.

The bottom surface of the gas storage pipe is fixedly connected with a plurality of shunt pipes, and the shunt pipes are evenly distributed on the bottom surface of the gas storage pipe.

[0013] For the provided carbon dioxide tank, when the control cabinet has been used for a long time and there is smoke inside due to overheating, the valve can be opened, and the carbon dioxide inside the carbon dioxide tank can be injected into the gas storage pipe through the fixed pipe and sprayed out through the shunt pipes, so as to quickly extinguish the smoke inside, making it safer during use, ensuring the safety of the operators, and providing convenience for handling emergencies.

[0014] The end of the shunt pipe is fixedly installed with an atomizing nozzle; the gas storage pipe is fixedly installed on the inner top surface of the control cabinet through a second fixing seat.

[0015] An atomizing nozzle is fixedly installed at the end of the shunt pipe, making the spraying effect better and saving the usage amount of carbon dioxide.

[0016] On the side wall surface of the cabinet door, a third fixing seat is fixedly installed. Between the third fixing seats, a connecting seat is movably hinged. On one side of the connecting seat, a protective cover is fixedly connected. The position of the protective cover corresponds to the positions of the display screen and the control buttons.

[0017] When not using the control, the protective cover can be flipped to one side so that the protective cover covers the outside of the display screen and the control buttons, preventing external wear and playing a protective role for the display screen and the control buttons, and increasing the service life of the control cabinet.

[0018] 1) By providing a first placement groove, a fixing plate, a placement plate, a card slot, and a positioning block, the placement plate can be placed in the corresponding first placement groove according to the size of the control module, and the placement plate can be pushed towards one end. With the provided positioning block and card slot, after the placement plate is placed in the corresponding first placement groove, the placement plate can be fixed and installed inside the control cabinet by engaging the positioning block with the card slot, making the installation more stable, the operation more convenient, and the overall load-bearing of the placement plate more stable.

[0019] 2) With the provided carbon dioxide tank, when the control cabinet has been used for too long and there is smoke inside due to overheating, the valve can be opened, and the carbon dioxide inside the carbon dioxide tank can be injected into the gas storage pipe through the fixed pipe and sprayed out through the shunt pipe, so as to quickly extinguish the smoke inside, making it safer to use, ensuring the safety of the operator, and providing convenience for handling emergencies.

[0020] 3) An atomizing nozzle is fixedly installed at the end of the shunt pipe, making the spraying effect better and saving the usage amount of carbon dioxide.

[0021] 4) When the control cabinet is not in use, the protective cover can be flipped to one side so that the protective cover covers the outside of the display screen and control buttons, preventing external wear, protecting the display screen and control buttons, and increasing the service life of the control cabinet.
