[0001] The present invention relates to the technical field of submerged arc furnaces, and specifically to a temperature control device for a submerged arc furnace. Background Art

[0002] A submerged arc furnace is also known as an electric arc furnace or a resistance furnace. It is mainly used for reducing and smelting ores, carbonaceous reducing agents, and solvent raw materials. It mainly produces ferroalloys such as ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, and silicomanganese alloy, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide. The load of the submerged arc furnace transformer is continuous and stable, with a low impedance voltage, a relatively large number of voltage regulation levels, a small step difference, and a strong overload capacity. It can be divided into two types: on-load and no-excitation voltage regulation. Generally, the first few levels output at a constant capacity, and the last few levels output at a constant current.

[0003] The Chinese patent discloses a "power generation system for utilizing the waste heat of the flue gas of a submerged arc furnace", with the publication number CN205642046U. The present utility model provides a power generation system for utilizing the waste heat of the flue gas of a submerged arc furnace, including a submerged arc furnace, a waste heat boiler, and multiple heat exchangers; a grate cooler is arranged at the discharge port of the submerged arc furnace, and multiple air chambers are arranged in the grate cooler, and a smoke hood is arranged on each air chamber; the number of smoke hoods corresponds to the number of heat exchangers, and each smoke hood is connected to a heat exchanger through a first pipeline; a first evaporator and a second evaporator are arranged in each heat exchanger; the first evaporators are connected in series through a second pipeline, one end of the second pipeline is connected to the first outlet of the waste heat boiler, and the other end of the second pipeline is connected to the first inlet of the waste heat boiler; the second outlet of the waste heat boiler is connected to a steam turbine through a third pipeline, and the steam turbine is connected to a generator. The present utility model reasonably utilizes the heat of a large amount of flue gas generated during the production process of calcium silicate smelting, greatly improves the waste heat recovery and utilization efficiency of the smelting process, and increases the power generation; the Chinese patent discloses a "waste heat boiler for the waste gas of a submerged arc furnace", with the publication number CN202733861U. The present utility model discloses a waste heat boiler for the waste gas of a submerged arc furnace, including a drum, a superheater, an economizer, a steel frame, a flue gas inlet device, a flue gas outlet device, a front water-cooled wall, an intermediate water-cooled partition wall, and a rear water-cooled wall.

[0004] Although the above-mentioned patent can achieve the collection and reuse of the hot gas from the submerged arc furnace, there are still the following problems: The hot gas discharged during the operation of the submerged arc furnace contains various impurities. If these impurities are not effectively intercepted, they will flow into the regenerator along with the trend. With the long-term continuous operation of the submerged arc furnace, this situation will accumulate continuously, thereby causing damage to the regenerator. The current interception devices have certain drawbacks. After long-term use, these interception devices will become difficult to clean. When it is necessary to clean them, it often takes a lot of time. This will not only have a negative impact on the normal production efficiency, resulting in the delay of the production process, but also increase the labor intensity of the workers. The workers may need to spend more energy and physical strength to complete these maintenance tasks that should be relatively convenient, bringing many inconveniences to the entire production process. Summary of the Invention

[0005] The purpose of the present invention is to provide a temperature control device for a submerged arc furnace, aiming to solve the problem that the interception device for collecting the hot gas of the submerged arc furnace in the prior art is not convenient to clean, resulting in the delay of the production process and increasing the labor intensity of the workers.

[0015] A limiting strip is fixed on the flipping groove plate, and a connecting member is provided on the storage cavity. The connecting member is in transmission connection with the limiting strip so that the flipping groove plate and the limiting strip can flip in the connecting pipe and the storage cavity.

[0016] Preferably, the connecting member includes a rotating shaft fixed on the storage cavity and a limiting sliding plate rotatably sleeved on the rotating shaft;

[0017] A sliding groove adapted for guiding and sliding with the limiting strip is provided on the limiting sliding plate so that when the flipping groove plate flips, the limiting strip can slide along the sliding groove.

[0018] Preferably, the cleaning assembly includes a cleaning telescopic device fixed on the flipping groove plate in the first cavity, a cleaning carrier plate fixedly connected to the movable section of the cleaning telescopic device, and a transmission assembly mounted on the cleaning carrier plate;

[0019] A brush disc is provided on the transmission assembly so that the brush disc can move in the up-down, front-back directions under the action of the transmission assembly to wipe off the debris on the filter plate.

[0024] Preferably, first fixing plates and second fixing plates are respectively fixed at the left and right ends of the fixed pipe, the connecting pipe, and the expanding and collecting pipe, and adjacent first fixing plates and second fixing plates are connected by a plurality of sets of clamping assemblies.

[0032] The beneficial effects are as follows: 1. After the collection pipe has been used for a long time, a considerable amount of sundries will be intercepted on the filter plate. If these sundries are not cleaned in time, it is very likely that the holes of the filter plate will be blocked. Once the holes are blocked, the amount of hot air that can flow through will become quite small. When cleaning, with the driving of the first driving device, the rotating rod can start to rotate. As the rotating rod rotates, the two flipping trough plates will flip down from the storage cavity. After that, the cleaning component and the top inserting component cooperate with each other, so that the brush disk can effectively wipe the sundries on the holes of the filter plate. The wiped sundries will be sucked away by the suction component in time. This cleaning method not only significantly improves the cleaning effect of the filter plate, but also greatly improves the cleaning efficiency because manual cleaning is not required.

[0033] 2. When the flipping groove plate is in a non - use state, it can be flipped into the storage cavity for storage. This can effectively avoid the situation where the flipping groove plate blocks the inside of the connection pipe, thereby achieving the purpose of facilitating the storage of the flipping groove plate. Further, in the actual operation process or equipment operation scenario, when the flipping groove plate does not need to perform its specific function, if it is placed randomly, it is very likely to accidentally enter the inside of the connection pipe and cause blockage. By providing a storage cavity and allowing the flipping groove plate to be flipped into it for storage. This measure not only makes the storage of the flipping groove plate well - organized, but also from the perspective of the overall operation stability and safety of the equipment, it avoids a series of potential problems that may be caused by the flipping groove plate blocking the connection pipe, thereby improving the reliability and smoothness of the operation of the entire system or equipment.

[0034] 3. By the mutual adaptation of the hanging plate and the hanging block, the connection between the fixed pipe, the connection pipe and the expansion collection pipe can be better, improving the stability between the fixed pipe, the connection pipe and the expansion collection pipe. Moreover, it is not necessary for workers to manually screw bolts, further reducing the labor intensity of the work. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0046] The following further describes the detailed implementation manners of the submerged arc furnace temperature control device of the present invention with reference to the accompanying drawings.

[0047] As Figures 1 - 10 shown, a submerged arc furnace temperature control device is mainly used to collect the waste heat of the submerged arc furnace 1, and then store the waste heat in the regenerator 2. When the submerged arc furnace 1 needs to be heated up, the heat can be conveyed into the heating pipe to heat the furnace bottom of the submerged arc furnace 1. However, sundries will be carried by the hot air flow during the collection process. If these sundries accumulate in the regenerator 2 for a long time, it will damage the inside of the regenerator 2. At present, there are also devices for filtering the hot air flow, but it is not convenient to clean the filtering device, which increases the labor cost of workers.

[0048] In this embodiment, when the submerged arc furnace 1 needs to be cooled down, the outside air can be extracted through a blower, and the furnace body can be cooled through a cooling pipe. The structure and principle of using the waste heat of the submerged arc furnace 1 to heat the furnace body are prior arts and will not be elaborated here in detail.

[0055] A first traction member 31 is fixed on the inner wall of the first groove 29. In this embodiment, the first traction member 31 includes a first tension spring and a first telescopic rod. The first tension spring is sleeved on the first telescopic rod. Under the action of the first tension spring, the hanging plate 2603 can be moved towards the side close to the hanging block 28. The other end of the first traction member 31 is fixedly connected to the telescopic sleeve plate 2602. A second traction member 32 is fixed on the sliding plate 2601.

[0056] During use, first insert the hanging plate 2603 into the second groove 27. Then, under the action of the first traction member 31, the hanging plate 2603 will be pulled to make the hanging plate 2603 stuck on the hanging block 28. Then, under the action of the first traction member 31 and the second traction member 32, the hanging plate 2603 can be tightly stuck on the hanging block 28, improving the connection stability between the hanging plate 2603 and the hanging block 28.

[0065] Working principle: During use, when the filter plate 5 in the connecting tube 402 needs to be cleaned, the first driving device 15 is started. After the first driving device 15 is started, it can drive the rotating rod 13 to rotate.
