Description

Technical Field

[0001] This utility model relates to the field of alloy continuous casting machine melt technology, and in particular to an alloy continuous casting machine melt slag removal device. Background Technology

[0002] Traditional slag removal methods have significant limitations in terms of efficiency, effectiveness, and environmental protection, and cannot meet the urgent needs of modern industry for efficient, automated, and intelligent slag removal technology. Traditional slag removal equipment suffers from problems such as low efficiency, inconvenient maintenance, and secondary slag adhesion.

[0003] Therefore, this utility model provides a slag removal device for alloy continuous casting machine melt. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a slag removal device for alloy continuous casting machine melt.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a slag removal device for alloy continuous casting machine melt, comprising a storage tank, a groove seat arranged around the inner wall of the storage tank, a chemical injection assembly installed in the middle of the storage tank and the groove seat, a cover plate provided at the top of the storage tank, a rotary motor provided at the upper middle end of the cover plate, a stirring frame connected to the lower end of the rotary motor, a chemical dosing hopper provided at the upper right of the cover plate, and slag filter assemblies installed on both sides of the cover plate;

[0006] The filter cake assembly includes an electric telescopic rod that passes symmetrically through both sides of the cover plate, and fixing screws are provided on both sides of the bottom end of the electric telescopic rod. A filter cake plate is provided at the bottom end of the electric telescopic rod and the fixing screws, and a ring of outward-expanding scrapers is evenly distributed on the top outer wall of the filter cake plate along its circumference.

[0007] A discharge pipe is provided at the lower left of the storage tank; and a filter assembly is installed at the bottom of the discharge pipe, with a receiving bucket placed at the bottom of the filter assembly.

[0008] In a preferred embodiment, the filter plate is connected to an outward-expanding scraper via an electric telescopic rod to form a lifting structure, and the blade of the outward-expanding scraper is inclined outward at 30°.

[0009] The technical advantages of adopting the above-mentioned further solution are as follows: By setting up a filter cake assembly, which is equipped with two sets of electric telescopic rods that start simultaneously, the telescopic movement is achieved through electric power. The telescopic movement of the electric telescopic rods causes the filter cake plate to move up and down inside the injection tank and storage tank. The introduction of electric telescopic rods realizes the automatic lifting and lowering of the filter cake plate without manual intervention, which significantly improves the slag removal efficiency. The electric telescopic rods are tightly connected to the filter cake plate through fixing screws. The symmetrical design of the electric telescopic rods prevents the equipment from shaking or deviating, ensuring precise control and ensuring the stability of the filter cake plate during the lifting and lowering process.

[0010] In a preferred embodiment, the electric telescopic rod is connected to the filter plate and the outward scraper via fixing screws to form a disassembly structure, and the bottom of the filter plate is designed to be slightly concave.

[0011] The technical advantages of adopting the above-mentioned further solution are as follows: the lifting range of the electric telescopic rod covers the bottom to top area of ​​the injection tank and storage tank; automated operation ensures the continuity and stability of the slag removal process, reduces equipment downtime, ensures that the filter plate can fully contact the melt and slag, and the filter plate surface is provided with uniformly distributed filter holes and slits to intercept solid slag in the melt. The bottom of the filter plate is designed with a slightly concave shape, which helps to evenly distribute the flow path of the melt, avoids excessively fast or slow local flow rates, and improves the efficiency of the filter plate. The uniformity of filtration ensures consistent purity of the melt. The filter holes and gaps of the filter plate can efficiently intercept solid slag in the melt, improving the purity of the melt. When the filter plate descends to the bottom, the melt passes through the filter holes, and the slag is intercepted on the surface of the filter plate. The outward-expanding scraper is evenly distributed along the circumference of the top outer wall of the filter plate. Inclined outward at 30°, it can automatically clean the inner surface of the injection tank, reducing the maintenance frequency of the filter plate. The design of the outward-expanding scraper effectively removes slag adhering to the surface of the filter plate or the inner wall of the storage tank, preventing secondary adhesion of slag.

[0012] In a preferred embodiment, the filter assembly includes a mounting bracket and a filter plate, with the mounting bracket installed at the bottom end of the feed pipe and the filter plate connected to the bottom of the mounting bracket.

[0013] The technical effect of adopting the above-mentioned further solution is that the filtered and scraped slag is concentrated to the bottom of the injection tank or storage tank through the lifting and lowering movement of the filter plate. The slag concentrated at the bottom can be discharged into the filter assembly through the discharge pipe for filtration and discharge.

[0014] In a preferred embodiment, the mounting bracket and the filter plate are movably connected.

[0015] The technical effect of adopting the above-mentioned further solution is to ensure the continuous and efficient operation of the equipment, and the dual filtration of the filter cake plate and the filter plate ensures the high purity of the melt.

[0016] In a preferred embodiment, the drug injection assembly includes a drug injection tank, which is disposed in the middle of the slot base. The top of the drug injection tank is connected to a dispensing pipe, and the lower end of the dispensing pipe is connected to a threaded pipe with a discharging nozzle on its outer surface.

[0017] The technical effect of adopting the above-mentioned further solution is that: the tank is located at the top of the storage tank, and the injection barrel, which is mainly used to support the injection assembly, is placed inside the storage tank to ensure the stability of the injection barrel installation. The injection barrel is used to store the agent, and the user manually adds the agent. The agent enters the storage tank through the dosing hopper and mixes with the melt.

[0018] In a preferred embodiment, the injection tank is connected in sequence to a threaded pipe via an injection pipe to form a continuous drug delivery channel, wherein the injection pipe is a hollow tubular structure.

[0019] The technical effect of adopting the above-mentioned further solution is as follows: the agent is transported to the storage tank through the delivery pipe to react with impurities in the melt, generating easily separable slag, adsorbing tiny inclusions in the melt, improving the purity of the melt, and the threaded pipe connects the delivery pipe and the discharge nozzle to ensure accurate delivery of the agent. The discharge nozzle sprays the agent evenly into the melt in the storage tank to achieve the purification or modification of the melt.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] The system incorporates a filter cake assembly with two sets of electrically driven telescopic rods that operate simultaneously. These rods, powered by electricity, extend and retract, causing the filter cake plate to rise and fall within the injection tank and storage tank. This automatic movement of the electric telescopic rods eliminates the need for manual intervention, significantly improving slag removal efficiency. The electric telescopic rods are securely connected to the filter cake plate with fixing screws. Their symmetrical design prevents equipment swaying or shifting, ensuring precise control and stability during the lifting process. The lifting range of the electric telescopic rods covers the bottom to top of the injection tank and storage tank. This automated operation ensures the continuity and stability of the slag removal process, reduces equipment downtime, and guarantees that the filter cake plate makes full contact with the melt and slag. The filter plate has evenly distributed filter holes and slits to intercept solid slag in the melt. The bottom of the filter plate is designed to be slightly concave, which helps to evenly distribute the flow path of the melt, avoid local flow rates that are too fast or too slow, improve the uniformity of filtration, and ensure the purity of the melt. The filter holes and slits of the filter plate can efficiently intercept solid slag in the melt and improve the purity of the melt. When the filter plate descends to the bottom, the melt passes through the filter holes, and the slag is intercepted on the surface of the filter plate. The outward-expanding scraper is evenly distributed along the circumference of the top outer wall of the filter plate and tilts outward at 30° to automatically clean the inner surface of the injection tank, reducing the maintenance frequency of the filter plate. The design of the outward-expanding scraper effectively removes slag adhering to the surface of the filter plate or the inner wall of the storage tank, preventing secondary adhesion of slag.

[0028] Example

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a technical solution: a slag removal device for alloy continuous casting machine melt, including a storage tank 1, a groove seat 2 is arranged around the inner wall of the storage tank 1, a chemical injection component 3 is installed in the middle of the storage tank 1 and the groove seat 2, a cover plate 4 is provided at the top of the storage tank 1, a rotary motor 5 is provided at the upper middle end of the cover plate 4, a stirring frame 6 is connected to the lower end of the rotary motor 5, a chemical dosing hopper 7 is provided at the upper right of the cover plate 4, and slag filter components 8 are installed on both sides of the cover plate 4;

[0030] The filter cake assembly 8 includes an electric telescopic rod 801, which passes symmetrically through both sides of the cover plate 4. Fixing screws 802 are provided on both sides of the bottom end of the electric telescopic rod 801. A filter cake plate 803 is provided at the bottom end of the electric telescopic rod 801 and the fixing screws 802. A ring of outwardly expanding scrapers 804 is evenly distributed on the top outer wall of the filter cake plate 803 along its circumference.

[0031] A discharge pipe 9 is located on the lower left side of storage tank 1; a filter assembly 10 is installed at the bottom of the discharge pipe 9, and a receiving bucket 11 is placed at the bottom of the filter assembly 10. Specifically, firstly, storage tank 1 is used to store alloy melt and is the core container of the entire system. A cover plate 4 is installed on the top of storage tank 1, covering the top of storage tank 1 for sealing and fixing other components. A rotary motor 5 is installed on the cover plate 4 to drive the stirring rack 6 to rotate. The stirring rack 6 rotates inside storage tank 1 and injection tank 301 to fully mix the melt and the agent, ensuring uniform distribution of the agent. The tank seat 2 is located on the top of storage tank 1 and is mainly used to support the injection tank 301, which is placed inside storage tank 1 to ensure the stability of the injection tank 301 installation. The injection tank 301 is used for storage. The reagent is manually added by the user. It enters the storage tank 1 through the dosing hopper 7 and mixes with the melt. The reagent is then transported to the storage tank 1 through the dosing pipe 302 to react with impurities in the melt, generating easily separable slag. This slag adsorbs tiny inclusions in the melt, improving its purity. A threaded pipe 303 connects the dosing pipe 302 and the discharge nozzle 304 to ensure precise dosing. The discharge nozzle 304 evenly sprays the reagent into the melt within the storage tank 1 to purify or modify it. A filter assembly 8 is installed, equipped with two sets of electrically operated telescopic rods 801 that simultaneously activate. Driven by electricity, the telescopic rods 801 cause the filter plate 803 to rise and fall within the dosing tank 301 and the storage tank 1. The introduction of the electric telescopic rod 801 enables the automatic lifting and lowering of the filter plate 803 without manual intervention, significantly improving slag removal efficiency. The electric telescopic rod 801 is tightly connected to the filter plate 803 via fixing screws 802. The symmetrical design of the electric telescopic rod 801 prevents equipment swaying or deviation, ensuring precise control and stability of the filter plate 803 during lifting and lowering. The lifting range of the electric telescopic rod 801 covers the bottom to top area of ​​the injection tank 301 and storage tank 1. Automated operation ensures the continuity and stability of the slag removal process, reduces equipment downtime, and ensures that the filter plate 803 can fully contact the melt and slag. The surface of the filter plate 803 has evenly distributed filter holes and slits to intercept solid slag in the melt. The bottom of the filter plate 803 is designed with a slightly concave shape. This concave shape helps to evenly distribute the flow path of the melt, avoids excessively fast or slow flow rates in some areas, improves the uniformity of filtration, and ensures consistent purity of the melt. The filter holes and slits of the filter plate 803 can efficiently intercept solid slag in the melt, improving melt purity. When the filter plate 803 descends to the bottom, the melt passes through the filter holes, and the slag is intercepted on the surface of the filter plate 803. The outward-expanding scraper 804 is evenly distributed along the circumference of the top outer wall of the filter plate 803 and tilts outward at 30° to automatically clean the inner surface of the injection tank 301, reducing the maintenance frequency of the filter plate 803. The design of the outward-expanding scraper 804 effectively removes slag adhering to the surface of the filter plate 803 or the inner wall of the storage tank 1.To prevent secondary adhesion of slag, the filtered and scraped slag is concentrated at the bottom of the injection tank 301 or storage tank 1 by the lifting movement of the filter plate 803. The slag concentrated at the bottom can be discharged into the filter assembly 10 through the discharge pipe 9 for filtration and discharge, ensuring the continuous and efficient operation of the equipment. The dual filtration of the filter plate 803 and the filter plate 1002 ensures the high purity of the melt. Through this technical solution, the filter assembly 8 achieves automated, efficient, and stable slag removal operation, solving the problems of low efficiency, inconvenient maintenance, and secondary slag adhesion in traditional slag removal equipment. The filter cake assembly 8 is equipped with two sets of electrically operated telescopic rods 801 that activate simultaneously. Driven by electricity, these rods extend and retract, causing the filter cake plate 803 to rise and fall within the injection tank 301 and storage tank 1. The introduction of the electric telescopic rods 801 enables automatic raising and lowering of the filter cake plate 803 without manual intervention, significantly improving slag removal efficiency.

The symmetrical design of the electric telescopic rods 801 prevents equipment swaying or deviation, ensuring precise control and guaranteeing the stability of the filter cake plate 803. In terms of stability during the lifting process, the lifting range of the electric telescopic rod 801 covers the bottom to top area of ​​the injection tank 301 and storage tank 1. Automated operation ensures the continuity and stability of the slag removal process, reduces equipment downtime, and ensures that the filter plate 803 can fully contact the melt and slag. The surface of the filter plate 803 is provided with evenly distributed filter holes and filter gaps to intercept solid slag in the melt. The bottom of the filter plate 803 is designed with a slightly concave shape, which helps to evenly distribute the flow path of the melt, avoids excessively fast or slow local flow rates, improves the uniformity of filtration, and ensures... The purity of the melt is consistent. The filter holes and gaps of the filter plate 803 can efficiently intercept solid slag in the melt, improving the purity of the melt. When the filter plate 803 descends to the bottom, the melt passes through the filter holes, and the slag is intercepted on the surface of the filter plate 803. The outward-expanding scraper 804 is evenly distributed along the circumference of the top outer wall of the filter plate 803. Inclined outward at 30°, it can automatically clean the inner surface of the injection tank 301, reducing the maintenance frequency of the filter plate 803. The design of the outward-expanding scraper 804 effectively scrapes off the slag adhering to the surface of the filter plate 803 or the inner wall of the storage tank 1, preventing secondary adhesion of slag.

[0032] Going further, such as Figure 1 and Figure 4As shown, it also includes a filter assembly 10, which includes a mounting bracket 1001 and a filter plate 1002. The mounting bracket 1001 is installed at the bottom of the feed pipe 9, and the bottom of the mounting bracket 1001 is connected to the filter plate 1002. The advantage of this technical solution is that by setting up the filter assembly 10, the filtered and scraped slag is concentrated to the bottom of the injection tank 301 or storage tank 1 through the lifting movement of the filter plate 803. The slag concentrated at the bottom can be discharged into the filter assembly 10 through the feed pipe 9 for filtration and discharge, ensuring the continuous and efficient operation of the equipment. The dual filtration of the filter plate 803 and the filter plate 1002 ensures the high purity of the melt.

[0033] The above solutions also suffer from problems such as leakage, waste, and inconvenience in maintenance that exist in traditional drug delivery systems, such as... Figure 1 and Figure 2 As shown: In this solution, the drug injection assembly 3 includes a drug injection tank 301. The drug injection tank 301 is placed in the middle of the slot 2, and the top of the drug injection tank 301 is connected to a dispensing pipe 302. The lower end of the dispensing pipe 302 is connected to a threaded pipe 303, and the outer surface of the threaded pipe 303 is provided with a drug discharge nozzle 304. The base 2 is located on top of the storage tank 1 and is mainly used to support the injection tank 301 of the injection assembly 3, which is placed inside the storage tank 1 to ensure the stability of the injection tank 301. The injection tank 301 is used to store the reagent. The user adds the reagent manually. The reagent enters the storage tank 1 through the dosing hopper 7 and mixes with the melt. The reagent is transported to the storage tank 1 through the dosing pipe 302 to react with impurities in the melt, generating easily separable slag. It adsorbs small inclusions in the melt and improves the purity of the melt. The threaded pipe 303 connects the dosing pipe 302 and the discharge nozzle 304 to ensure accurate dosing of the reagent. The discharge nozzle 304 sprays the reagent evenly into the melt in the storage tank 1 to achieve the purification or modification of the melt.

[0034] Working principle:

[0035] like Figure 1-4 As shown:

[0036] First, the storage tank 1 is used to store the alloy melt and is the core container of the entire system. A cover plate 4 is installed on top of the storage tank 1, covering the top of the tank and used to seal and secure other components. A rotary motor 5 is mounted on the cover plate 4, driving the stirring rack 6 to rotate. The stirring rack 6 rotates inside the storage tank 1 and the injection tank 301, thoroughly mixing the melt and the reagent to ensure uniform distribution of the reagent. The tank seat 2 is located on top of the storage tank 1 and mainly supports the injection tank 301, which is placed inside the storage tank 1, ensuring the stability of the injection tank 301. The injection tank 301 is used to store the reagent, which is manually added by the user. The reagent enters the storage tank 1 through the dosing hopper 7 and mixes with the melt. The reagent is then transported into the storage tank 1 through the dispensing pipe 302. The reagent reacts with impurities in the melt to generate easily separable slag, adsorbing tiny inclusions in the melt and improving melt purity. The threaded pipe 303 connects the dispensing pipe 302 and the discharge nozzle 304 to ensure precise reagent dispensing. The discharge nozzle 304 evenly sprays the reagent into the melt within the storage tank 1 to purify or modify the melt. A filter assembly 8 is provided, equipped with two sets of electrically operated telescopic rods 801 that activate simultaneously. Driven by electricity, the telescopic rods 801 cause the filter plate 803 to move up and down within the dispensing tank 301 and storage tank 1. The introduction of the electric telescopic rods 801 enables automatic lifting and lowering of the filter plate 803 without manual intervention, significantly improving slag removal efficiency. 1. The filter plate 803 is tightly connected to the fixing screw 802. The symmetrically designed electric telescopic rod 801 prevents the equipment from shaking or shifting, ensuring precise control and stability of the filter plate 803 during lifting. The lifting range of the electric telescopic rod 801 covers the bottom to top area of ​​the injection tank 301 and storage tank 1. Automated operation ensures the continuity and stability of the slag removal process, reduces equipment downtime, and ensures that the filter plate 803 can fully contact the melt and slag. The surface of the filter plate 803 is provided with uniformly distributed filter holes and filter gaps to intercept solid slag in the melt. The bottom of the filter plate 803 is designed with a slightly concave shape, which helps to evenly distribute the flow path of the melt and avoid local flow rates that are too fast or too slow. To improve filtration uniformity and ensure consistent melt purity, the filter plates 803, with their filter holes and gaps, efficiently intercept solid slag in the melt, thus enhancing melt purity. When the filter plates 803 descend to the bottom, the melt passes through the filter holes, while the slag is trapped on the surface of the filter plates 803. Outward-expanding scrapers 804 are evenly distributed along the circumference of the top outer wall of the filter plates 803, tilting outwards at a 30° angle to automatically clean the inner surface of the injection tank 301, reducing the maintenance frequency of the filter plates 803. The design of the outward-expanding scrapers 804 effectively removes slag adhering to the surface of the filter plates 803 or the inner wall of the storage tank 1, preventing secondary slag adhesion. The filtered and scraped slag is concentrated at the bottom of the injection tank 301 or storage tank 1 through the lifting and lowering motion of the filter plates 803.The slag concentrated at the bottom can be discharged through the feed pipe 9 into the filter assembly 10 for filtration and then discharged into the receiving bucket 11 for collection, ensuring the continuous and efficient operation of the equipment. The dual filtration of the slag plate 803 and the filter plate 1002 ensures the high purity of the melt.
