Description

Technical Field

[0001] This utility model relates to the field of oxygen lance cooling technology, and more specifically, to an oxygen lance cooling water supply device. Background Technology

[0002] In the metallurgical industry, the oxygen lance is a core piece of equipment in high-temperature smelting, and the stability of its cooling water supply system directly affects the equipment's service life and process efficiency. Traditional cooling systems often rely on external refrigeration units to maintain the coolant's low temperature. However, such equipment is energy-intensive, bulky, and easily affected by ambient temperature during the heat transfer process, leading to significant temperature fluctuations in the coolant within the storage container. Especially in high-temperature workshops, the coolant absorbs heat and is difficult to cool down quickly, directly impacting the oxygen lance's cooling effect.

[0003] Furthermore, metal debris mixed in the oxygen lance cooling return water can easily cause pipe blockage and equipment wear. Traditional filtration devices mostly use fixed filter screens to intercept impurities, requiring frequent shutdowns for disassembly and cleaning. This not only increases labor maintenance costs, but repeated disassembly and assembly may also damage the sealing structure, leading to coolant leakage or secondary pollution. Therefore, in response to the above technical problems, an oxygen lance cooling water supply device is proposed here. Utility Model Content

[0004] The purpose of this invention is to provide an oxygen lance cooling water supply device that ensures a constant low temperature of the coolant by combining dynamic temperature regulation with an insulation layer. It also uses an inclined filter screen to guide debris to slide down by gravity and uses the lifting and lowering of a sliding plate to trigger vibration to assist in the removal of stubborn impurities. Furthermore, the opening and closing of the debris discharge port is controlled synchronously by the displacement of the sliding plate to achieve automatic switching between filtration and cleaning states, which greatly reduces the frequency of manual intervention while ensuring cooling efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 The present invention discloses an oxygen lance cooling water supply device, comprising a water storage tank 1, a water pump 3 fixedly connected to the inner side of the water storage tank 1, a supply pipe 4 fixedly connected to the outer side of the water pump 3, a refrigeration mechanism installed on the inner and outer sides of the water storage tank 1, a filter tank 8 fixedly connected to the outer side of the water storage tank 1, a return channel 9 opened between the filter tank 8 and the water storage tank 1, two sets of symmetrically arranged positioning plates 11 fixedly connected to the inner side of the filter tank 8, a first sliding plate 12 and a second sliding plate 13 respectively placed on the upper side of the two sets of positioning plates 11, and the first sliding plate 12 and the second sliding plate 13 are slidably connected to the inner side of the water storage tank 1, a filtration mechanism is installed between the first sliding plate 12 and the second sliding plate 13, and a lifting mechanism is installed on the upper side of the filter tank 8.

[0025] A replenishment pipe 2 is fixedly connected to the upper side of the water tank 1. A piston is detachably connected to the end of the replenishment pipe 2. The replenishment pipe 2 is designed to facilitate the replenishment of coolant at any time, and the detachable piston design makes maintenance and cleaning convenient.

[0026] The cooling mechanism includes a water temperature sensor 5, a semiconductor cooler 6, and an insulation shell 7. The water temperature sensor 5 is fixedly connected to the inside of the water storage tank 1, and the semiconductor cooler 6 is fixedly connected to the outside of the water storage tank 1. The cold end of the semiconductor cooler 6 is located inside the water storage tank 1, and the hot end of the semiconductor cooler 6 is located outside the water storage tank 1. The insulation shell 7 is fixedly connected to the outside of the water storage tank 1 and completely covers the outer surface of the water storage tank 1. The semiconductor cooler 6 directly cools the liquid by embedding its cold end inside the water storage tank 1 and dissipates heat by externally dissipating heat. In conjunction with the water temperature sensor 5, the cooling power is adjusted in real time to achieve precise and stable control of the coolant temperature.

[0027] A return pipe 10 is fixedly connected to the upper side of the water filter tank 8. The return pipe 10 guides the used coolant back to the water filter tank 8, realizing the recycling of coolant.

[0028] The filtration mechanism includes a filter screen 14, a chip discharge port 15, and an opening 16. The filter screen 14 is fixedly connected between the first slide plate 12 and the second slide plate 13. The filter screen 14 is a mesh-like hollow structure made of metal material. The filter screen 14 is installed at an angle. The opening 16 is opened on the outside of the first slide plate 12, and the lower end of the filter screen 14 is located at the bottom edge of the opening 16. The chip discharge port 15 is opened on the outside of the water filter tank 8. The angled design of the filter screen 14 facilitates the sliding of debris, which is discharged through the chip discharge port 15 to keep the coolant clean.

[0029] When the opening 16 is aligned with the chip discharge port 15, the upper ends of the first sliding plate 12 and the second sliding plate 13 abut against the top of the inner side of the water storage tank 1. At this time, the filter screen 14 is in the cleaning position, which facilitates the discharge of debris.

[0030] The lifting mechanism includes a vertical plate 17, a drive motor 18, a rotating shaft 19, and a connecting rope 20. The vertical plate 17 is fixedly connected to the upper side of the water filter tank 8, and there are two sets of vertical plates 17 arranged symmetrically. The drive motor 18 is fixedly connected to the outside of one set of vertical plates 17. The rotating shaft 19 is rotatably connected between the two sets of vertical plates 17. The connecting rope 20 is fixedly connected to the outside of the rotating shaft 19, and there are two sets of connecting ropes 20 arranged horizontally. The lifting mechanism drives the rotating shaft 19 to rotate through the drive motor 18, thereby realizing the lifting and lowering movement of the first sliding plate 12 and the second sliding plate 13.

[0031] The ends of the two sets of connecting ropes 20 are respectively threaded through the upper side of the filter water tank 8 and fixedly connected to the upper side of the first slide plate 12 and the second slide plate 13. The traction effect of the connecting ropes 20 enables the slide plate to accurately control the position of the filter screen 14 and realize the switching between the filtering and cleaning states.

[0032] The working principle of the oxygen lance cooling water supply device according to the embodiment is as follows: when the oxygen lance is in working condition and needs to be cooled, the coolant pre-stored in the water tank 1 is continuously delivered to the cooling part of the oxygen lance through the supply pipe 4 by the built-in water pump 3 to complete the cooling operation of the high-temperature components. During this process, since the cold end of the semiconductor cooler 6 is embedded in the water tank 1, and the water temperature sensor 5 monitors the coolant temperature in real time, the cooling mode is activated when the liquid temperature rise is detected to ensure that the coolant is always in a low temperature state. Combined with the fully covered heat insulation shell 7, a double temperature isolation structure is formed, which effectively reduces the influence of the external ambient temperature on the coolant and maintains a stable low temperature environment inside the water tank 1.

[0033] After cooling, the return liquid, carrying metal debris detached from the oxygen gun tip, enters the water filter tank 8 through the return pipe 10. The inclined metal filter screen 14 filters the return liquid through its mesh-like perforated structure, trapping the debris on its surface. The purified liquid is then re-injected into the water storage tank 1 through the bottom return channel 9 for recycling. When the oxygen gun stops working, the drive motor 18 drives the rotating shaft 19 to rotate, winding two sets of connecting ropes 20, simultaneously lifting the first slide plate 12 and the second slide plate 13 to the top of the water filter tank 8. This ensures that the opening 16 on the slide plate is precisely aligned with the chip discharge port 15 on the side wall of the tank. At this time, the inclined filter screen 14 allows the debris to slide along the mesh surface and be discharged through the chip discharge port 15 under the action of gravity. If the debris is difficult to detach due to strong adhesion, the drive motor 18 can be controlled to periodically reverse forward and backward. By winding and unwinding the connecting ropes 20, the slide plate repeatedly impacts the inner wall of the water filter tank 8, generating mechanical vibration that causes the debris to detach from the filter screen 14, significantly improving cleaning efficiency.

[0034] After the cleaning operation is completed, the drive motor 18 releases the connecting rope 20, and the first slide plate 12 and the second slide plate 13 fall back smoothly to the top of the positioning plate 11 under their own weight. This makes the chip discharge port 15 and the opening 16 completely misaligned, and restores the internal structure of the water filter tank 8 to a closed filtration state. In this way, through the dynamic cooperation between the lifting mechanism and the filtration mechanism, the impurities in the coolant circulation process are automatically removed, which not only ensures the purity of the coolant, but also avoids the tedious operation of manual cleaning, and significantly improves the operating efficiency and maintenance convenience of the oxygen lance cooling system.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
