Description

Technical Field

[0001] This invention relates to the field of slag treatment, and more particularly to an intelligent slag treatment device for metal smelting. Background Technology

[0002] In metal smelting furnaces, high-temperature molten slag and molten metal are splashed or washed onto the cooler furnace walls during a violent reaction, where they then condense and adhere to form slag. Timely cleaning of slag from metal smelting furnaces can increase output per unit area, reduce power consumption, ensure steel quality, and significantly extend the service life of expensive equipment such as refractory materials and electrodes. However, the cleaning work is generally carried out by workers using hydraulic breakers and pneumatic picks to knock the slag off the furnace walls. This method poses safety hazards, and manual operation cannot accurately control the tools, which can easily damage the furnace walls.

[0003] The distribution of slag in the furnace wall is not uniform, and cleaning the slag on the furnace wall requires a targeted approach. Existing scraping tools are unable to quickly solve the problem of slag adhesion, resulting in low cleaning efficiency. Moreover, most of the scraped slag is large in volume, and small pieces of slag are scattered everywhere, which is not conducive to the subsequent slag removal work. In addition, a large amount of dust is generated during the scraping process, which is harmful to human health and reduces the service life of the smelting furnace. Summary of the Invention

[0004] To overcome the shortcomings of metal smelting furnace slag removal, such as the lack of pores in the slag, making it difficult for scraping tools to penetrate the slag and reducing cleaning efficiency, the inconsistent size of the scraped slag, which is not conducive to subsequent transportation, and the generation of a large amount of dust during the scraping process, which is harmful to human health and reduces the service life of the smelting furnace, this invention provides an intelligent metal smelting furnace slag treatment device.

[0005] The technical implementation of this invention is as follows: an intelligent metal smelting slag treatment device, comprising a shell, a gas storage chamber, an air inlet valve, clamping blocks, a fixing plate, and a dust collector; the gas storage chamber is fixedly connected to the upper part of the shell; the air inlet valve is fixedly connected to the upper part of the gas storage chamber; four clamping blocks arranged in a circumferential array are fixedly connected to the lower part of the shell; a fixing plate is fixedly connected to the lower part of the shell and surrounded by the four clamping blocks; a dust collector is fixedly connected to the lower part of the fixing plate; it also includes scraping components and baffles; each clamping block is connected to a set of scraping components; a baffle is connected between adjacent scraping components.

[0006] Optionally, four hooks arranged in a circumferential array are fixed to the top of the housing.

[0007] Optionally, the scraping assembly includes a rotating plate, a top block, a scraper, a compression spring, a stop plate, a blower, and a gas delivery hose; each clamping block is connected to a rotating plate; a top block is slidably connected to the inner side of each rotating plate; a scraper is provided at the front end of the top block; a compression spring is fixedly connected to the rear end of the top block; two stop plates are fixedly connected to the inner side of each rotating plate, and each stop plate is connected to a compression spring; a blower is provided inside each rotating plate; a gas delivery hose is fixedly connected to the tail end of the blower; the gas delivery hose is connected to the gas storage chamber.

[0008] Optionally, the scraping assembly also includes electric push rods; two electric push rods are fixed to the inside of each rotating plate, and each electric push rod is connected to the rear end of the top block.

[0009] Optionally, the scraper shape is wavy.

[0010] Optionally, the baffle is made of a stretchable elastic material.

[0011] Optionally, the front end of the top block has several air outlets along the scraper trajectory.

[0012] Optionally, several air outlets at the lower part of the scraper are set at a certain angle and aligned with the inclined surface of the scraper, while several air outlets at the upper part of the scraper are set horizontally.

[0013] Optionally, each rotating plate has a first ventilation slot on its left and right sides; each baffle has a second ventilation slot, and the second ventilation slot communicates with the first ventilation slot.

[0014] Optionally, the scraping assembly also includes raised strips; each rotating plate has raised strips fixed to its bottom.

[0015] Beneficial effects: The scraper of this invention is designed with a wavy shape. The wavy shape can increase the contact area between the scraper and the slag, which is conducive to the scraper having more areas to embed into the slag and scrape the slag off the furnace wall. In addition, the wavy shape can create areas of different heights, which can break the connected slag during vibration and allow the slag to fall off in the form of small pieces.

[0016] This invention designs a baffle made of a stretchable elastic material. The baffle expands and contracts during the rotation of the rotating plate, ensuring that all scraping components are always engaged with the baffle to achieve a sealing effect. This guarantees that when scraping slag from the furnace wall, the slag will not splash randomly, but will be blocked and fall directly to the bottom of the metal smelting furnace. Not only can it prevent slag from splashing, but it can also guide dust through the baffle into the dust collector, preventing dust from flying around and not being completely collected.

[0017] This invention features a top block with several air outlets along the scraper trajectory at its front end. Gas supplied by the blower to the inside of the rotating plate can be ejected through these outlets. Due to the small size of the outlets and the high wind speed, the ejected gas can generate a certain impact force to collide with the slag, damaging its internal structure. This facilitates the scraper removing the slag from the furnace wall and reduces the occurrence of large-volume slag falling off. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1: A smart slag treatment device for metal smelting, such as... Figures 1-5As shown, it includes an outer shell 1, an air storage chamber 2, an air inlet valve 3, a scraping assembly, and a baffle 201; the air storage chamber 2 is fixedly connected to the upper part of the outer shell 1; the air inlet valve 3 is fixedly connected to the upper part of the air storage chamber 2; four clamping blocks 4 arranged in a circumferential array are fixedly connected to the lower part of the outer shell 1; a fixing plate 5 is fixedly connected to the lower part of the outer shell 1 and is surrounded by the four clamping blocks 4; a dust collector 6 is fixedly connected to the lower part of the fixing plate 5; each clamping block 4 is connected to a set of scraping assemblies; a baffle 201 is connected between adjacent scraping assemblies.

[0022] Four hook blocks 7 arranged in a circumferential array are fixed to the top of the outer shell 1; the hook lock of the external suspension equipment is engaged with the hook blocks 7. Under the joint action of the suspension equipment and the hook blocks 7, the entire equipment can be kept moving up and down stably, and the equipment can also be rotated to enhance the slag scraping effect.

[0023] The scraping assembly includes a rotating plate 101, a top block 102, a scraper 103, a compression spring 104, and a stop plate 105; each clamping block 4 is connected to a rotating plate 101; a top block 102 is slidably connected to the inner side of each rotating plate 101; a scraper 103 is provided at the front end of the top block 102; two compression springs 104 are fixedly connected to the rear end of the top block 102; two stop plates 105 are fixedly connected to the inner side of each rotating plate 101, and each stop plate 105 is connected to a compression spring 104; a blower 107 is provided inside each rotating plate 101; a gas delivery hose 108 is fixedly connected to the tail of the blower 107; the gas delivery hose 108 is connected to the gas storage chamber 2.

[0024] The scraping assembly also includes an electric push rod 106; two electric push rods 106 are fixedly connected to the inner side of each rotating plate 101, and each electric push rod 106 is connected to the rear end of the top block 102. The electric push rod 106 can directly push the top block 102 forward, so that the scraper 103 can directly embed into the slag to scrape off the slag, thereby achieving the cleaning effect.

[0025] The scraper 103 has a wavy shape, which increases the contact area between the scraper 103 and the slag. This allows the scraper 103 to have more areas embedded in the slag, scraping the slag off the furnace wall. The wavy shape also creates areas of varying heights, which can break up the connected slag during vibration, allowing the slag to fall off in small pieces.

[0026] The baffle 201 is made of a stretchable elastic material. The baffle 201 expands and contracts during the rotation of the rotating plate 101, ensuring that all scraping components are always engaged with the baffle 201 to achieve a sealing effect. This ensures that when scraping slag from the furnace wall, the slag will not splash randomly, but will be blocked and fall directly to the bottom of the metal smelting furnace. In addition to blocking the splashing of slag, it can also guide dust through the baffle 201 into the dust collector 6, preventing dust from flying around and not being completely collected.

[0027] Workers engage the hook lock of the suspension equipment with hook block 7, allowing the invention to enter the metal smelting furnace from the top and maintain a stable downward movement. Due to the complex conditions inside the metal smelting furnace, with varying slag thicknesses in different areas, targeted scraping is necessary to avoid damaging the furnace walls. Therefore, when the invention is at the top, the laser scanner 8 is activated first, and then the lifting function of the suspension equipment is used to scan the interior of the metal smelting furnace. The scanned data is compared and analyzed with existing furnace data to determine the slag thickness in different areas. This result is then synchronized to the control center, which can adjust parameters such as airflow, wind speed, and push rod force required for scraping different areas, ensuring proper slag removal. The slag removal process does not damage the furnace wall. After the scanning analysis is completed, all rotating plates 101 are rotated to 90 degrees, perpendicular to the outer shell 1. All baffles 201 rotate with the rotating plates 101. Because the baffles 201 are made of elastic material, all rotating plates 101 and baffles 201 are always combined to achieve a sealing effect. This ensures that when scraping slag off the furnace wall, the slag will not splash in all directions, but will be blocked and fall directly to the bottom of the metal smelting furnace, avoiding damage to the cleaning equipment from splashed slag and reducing the difficulty of cleaning. The baffles 201 can not only block the splashing of slag, but also guide the dust from the bottom of the baffles 201 into the dust collector 6, preventing dust from flying. After all the rotating plates 101 have rotated, the suspension equipment allows... The rotating plate 101 is in contact with the furnace wall. At this time, the external air pump delivers gas to the gas storage chamber 2 through the air inlet valve 3. The gas in the gas storage chamber 2 is then transported to the blower 107 through the gas delivery hose 108. The blower 107 then intermittently blows the gas into the rotating plate 101, providing the gas with a certain speed. The gas in the rotating plate 101 can push the top block 102 forward, and under the action of the compression spring 104, the top block 102 can achieve reciprocating motion. This can generate a vibration effect on the slag. Under the action of vibration, the easily detachable parts of the slag surface are shaken off, creating multiple holes. This allows the scraper 103 to embed itself into the slag through the holes and scrape the slag off the furnace wall. Furthermore, under the action of vibration, the internal structure of the adhered slag will also be... The vibration reduces the formation of large volumes of slag. After vibration, the electric push rod 106 controls the top block 102 to move forward. In this state, the electric push rod 106 holds the top block 102 in place and does not move backward. At this time, the scraper 103 is embedded inside the slag. Since the suspension device can drive the invention to rotate, the different scrapers 103 continuously stir inside the slag and cause the slag to detach from the furnace wall. The scraper 103 has a wavy shape, which increases the contact area between the scraper 103 and the slag, allowing more areas of the scraper 103 to embed inside the slag and scrape the slag off the furnace wall. The wavy shape also creates areas of varying heights, which can break the connected slag during vibration, allowing the slag to fall off in small pieces.

[0028] Example 2, based on Example 1, such as Figures 5-7 As shown, the top block 102 has several air outlets 10201 along the trajectory of the scraper 103 at its front end. The gas delivered by the blower 107 to the inside of the rotating plate 101 can be ejected through the air outlets 10201. Because the opening of the air outlets 10201 is small and the wind speed is high, the ejected gas can form a certain impact force to collide with the slag, destroy the internal structure of the slag, which is beneficial for the scraper 103 to scrape the slag off the furnace wall and reduces the occurrence of large volume slag falling off.

[0029] Several air outlets 10201 at the lower part of the scraper 103 are set at a certain angle and are aligned with the inclined surface of the scraper 103. Several air outlets 10201 at the upper part of the scraper 103 are set horizontally. The inclined air outlets 10201 can not only guide the air into the slag, but also blow it toward the inclined surface of the scraper 103, blowing off the slag remaining on the inclined surface of the scraper 103, thus avoiding the accumulation of slag on the blade surface and affecting the scraping effect.

[0030] Each rotating plate 101 has a first ventilation slot 10101 on its left and right sides; each baffle 201 has a second ventilation slot 20101, and the second ventilation slot 20101 is connected to the first ventilation slot 10101. Excess air inside the rotating plate 101 enters the baffle 201 through the first ventilation slot 10101, and then is ejected through the second ventilation slot 20101 at the front end of the baffle 201. The ejected air can form an air wall to prevent the dust generated during the slag scraping process from flying directly upward. After the dust flies downward, it is guided by the baffle 201 and directly collected by the dust collector 6.

[0031] After pushing the top block 102, the gas disperses to both sides and is ejected through the air outlet 10201 on the top block 102. This part of the gas acts directly on the slag. Because the opening of the air outlet 10201 is small and the wind speed is high, the ejected gas can form a certain impact force to collide with the slag and enter the interior of the slag through the gaps on the slag surface, further breaking down the internal structure of the slag and improving the scraping efficiency of the scraper 103. In the first two processes, the remaining gas enters the baffle 201 through the first ventilation slot 10101. The gas in the baffle 201 is then ejected from the second ventilation slot 20101. The ejected gas can form an air wall around it. The air wall can prevent the dust generated during the scraping of slag from flying directly upward and entering the outside of the metal smelting furnace, affecting the health of the workers. After being blocked by the air wall, the dust flies to the lower part of the dust collector 6 under the guidance of the baffle 201. The dust collector 6 then collects the dust with a strong suction.

[0032] Example 3, based on Examples 1 and 2, such as Figure 8As shown, the scraping assembly also includes a raised strip 109; each rotating plate 101 has a raised strip 109 fixed to its bottom. The raised strip 109 can collect all the slag that falls off the upper furnace wall and concentrate it in the middle of the bottom of the metal smelting furnace. This makes it convenient for workers to simply transport the slag accumulated in the middle of the bottom of the metal smelting furnace away, reducing the difficulty of cleaning and increasing the slag processing rate.

[0033] In metal smelting furnaces with an arc-shaped bottom, when the scraping area is about to reach the bottom, the operator can control the rotating plate 101 to rotate along the arc shape of the bottom, always keeping the rotating plate 101 in contact with the furnace wall. The rotation not only allows for slag scraping work on the special arc-shaped furnace bottom, but also allows the convex strip 109 to collect all the slag that has fallen off the upper furnace wall and concentrate it in the middle of the furnace bottom. This makes it convenient for the operator to simply transport the slag accumulated in the middle of the furnace bottom away, reducing the cleaning difficulty and increasing the slag processing rate.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
