Description

Technical Field

[0001] This application relates to the field of experimental electric furnace technology, and in particular to an experimental electric furnace device with a dust removal structure. Background Technology

[0002] During the use of experimental electric furnaces, dust accumulation is a key issue affecting experimental accuracy and equipment lifespan. Traditional electric furnaces typically rely on external dust removal equipment (such as bag filters and cyclone dust collectors) for fume treatment, but their effectiveness in cleaning adsorbed dust (such as oxide particles and experimental residues) on the internal walls and bottom of the furnace is limited.

[0003] In existing technologies, dust removal inside electric furnaces is mostly done by manual wiping or high-pressure airflow rinsing. Manual cleaning relies on the operator's experience, making it difficult to cover the tiny areas on the inner wall and bottom of the electric furnace. It also requires frequent shutdowns for maintenance and has low cleaning efficiency. Summary of the Invention

[0004] The purpose of this application is to provide an experimental electric furnace device with a dust removal structure to solve the above-mentioned problems. Through the synergistic design of hydraulic sealing, multi-dimensional scraper cleaning and airflow-assisted dust removal, it solves the problem of low dust removal efficiency of traditional electric furnaces, and is also automated. It can be widely used in materials science, metallurgical experiments and other fields, and significantly improves experimental accuracy and equipment life.

[0005] This application achieves the above objectives through the following technical solutions:

[0006] An experimental electric furnace device with a dust removal structure includes: an electric furnace and a furnace door; a hydraulic cylinder support fixedly connected to the electric furnace; a hydraulic cylinder fixedly mounted on the hydraulic cylinder support; a partition fixedly connected to the output end of the hydraulic cylinder, with an opening at the rear of the electric furnace for the partition to enter and exit, and a gap between the partition and the top of the electric furnace; an air inlet pipe and an air outlet pipe, one end of which is connected to the top of the electric furnace; and a scraper disposed in the gap between the electric furnace and the partition, and connected to a drive assembly capable of driving its lifting and translating, with bristles provided on the sides and bottom of the scraper.

[0007] In some embodiments, the drive assembly includes: a linear drive assembly with its output end moving in a vertical direction; a lifting bracket with its end fixedly connected to the output end of the linear drive assembly; a slide table fixedly connected to the lifting bracket; a lead screw with both ends rotatably connected to the slide table; a motor fixedly mounted on the slide table, with its output shaft fastened to the lead screw; a slider screwed to the lead screw and slidingly engaged with the slide table; and a connecting rod, wherein the slide table and the top of the electric furnace are respectively provided with a first sliding opening and a second sliding opening to avoid the connecting rod, the top end of the connecting rod passing through the first sliding opening and fixedly connected to the slider, and the bottom end of the connecting rod passing through the second sliding opening and fixedly connected to the scraper.

[0008] In some embodiments, a sealing plate is provided on the side of the partition connected to the hydraulic cylinder, and the hydraulic cylinder extends axially in the horizontal direction to drive the partition to move horizontally.

[0009] In some embodiments, the scraper abuts against the inner wall of the electric furnace on both sides, and there is a gap between the scraper and the electric furnace at both ends, so that the drive assembly can drive the scraper to reciprocate.

[0010] In some embodiments, the lead screw is horizontally arranged, and the second slide and the first slide extend along the lead screw axis.

[0011] Compared to existing technologies, this application achieves synergistic optimization of efficient dust removal and automated operation through innovative design. The linear drive component drives the scraper to rise and fall vertically, and the brush bristles rub against the inner wall of the electric furnace, removing adsorbed dust such as oxide particles and experimental residues. The cleaning coverage is more than 90% higher than traditional manual wiping. Airflow-assisted dust removal, with the air inlet and exhaust pipes working together, allows airflow to enter, and the dust scraped off by the scraper is discharged through the exhaust pipe with the airflow. Combined with external filtration equipment, this improves dust removal efficiency. Attached Figure Description

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0020] like Figure 1-3 As shown, an experimental electric furnace device with a dust removal structure includes: an electric furnace 1 and a furnace door 2; a hydraulic cylinder support 3, fixedly connected to the electric furnace 1; a hydraulic cylinder 4, fixedly mounted on the hydraulic cylinder support 3; a partition 5, fixedly connected to the output end of the hydraulic cylinder 4; an opening for the partition 5 to enter and exit at the rear of the electric furnace 1; a gap between the partition 5 and the top of the electric furnace 1; an air inlet pipe 7 and an exhaust pipe 8, one end of which is connected to the top of the electric furnace 1; a scraper 17, disposed in the gap between the electric furnace 1 and the partition 5, and connected to a drive assembly capable of driving its lifting and translating; and brush bristles provided on the sides and bottom of the scraper 17.

[0021] The electric furnace 1 and furnace door 2 in this embodiment are existing technologies. By opening the rear of the electric furnace 1 to allow the partition 5 to enter and exit, and by connecting the top of the electric furnace 1 through the air inlet pipe 7 and the exhaust pipe 8, airflow can be delivered into the electric furnace 1 and exhaust can be provided. When the partition 5 is fully inserted into the electric furnace 1, it can seal the gap between the partition 5 and the electric furnace 1 to prevent heat loss. The partition 5 is made of heat-resistant and heat-insulating material. The side of the scraper 17 abuts against the inner wall of the electric furnace 1. After the scraper 17 rises and falls, it directly rubs against the inner wall of the electric furnace 1 to scrape off the dust adsorbed on the inner wall of the electric furnace 1. The moving scraper 17 can rub against the bottom of the electric furnace 1, thereby scraping off the dust adsorbed on the bottom of the electric furnace 1. The bristles can be made of steel to improve durability.

[0022] In some embodiments, the drive assembly includes: a linear drive assembly 9, the output end of which moves in a vertical direction; a lifting bracket 10, the end of which is fixedly connected to the output end of the linear drive assembly 9; a slide table 18, which is fixedly connected to the lifting bracket 10; a lead screw 11, the two ends of which are rotatably connected to the slide table 18; a motor 12, which is fixedly mounted on the slide table 18 and the output shaft is fastened to the lead screw 11; a slider 13, which is screwed to the lead screw 11 and slides in cooperation with the slide table 18; and a connecting rod 14, the top of the slide table 18 and the top of the electric furnace 1 respectively having a first sliding opening 16 and a second sliding opening 15 to avoid the connecting rod 14, the top end of the connecting rod 14 passing through the first sliding opening 16 and fixedly connected to the slider 13, and the bottom end of the connecting rod 14 passing through the second sliding opening 15 and fixedly connected to the scraper 17.

[0023] The linear drive component 9 in this embodiment is existing technology. In some implementations, it is a lead screw slide or a synchronous belt linear drive module, which can drive the lifting bracket 10 to rise and fall. The volume of the slider 13 is greater than or equal to the cross-section of the first sliding opening 16, so as to prevent the slider 13 from falling into the first sliding opening 16 or sliding with the first sliding opening 16.

[0024] In some embodiments, a sealing plate 6 is provided on the side of the partition 5 connected to the hydraulic cylinder 4, and the hydraulic cylinder 4 extends axially in the horizontal direction so as to drive the partition 5 to move horizontally.

[0025] In this embodiment, after the partition 5 is fully inserted into the electric furnace 1, the sealing plate 6 can block the air vents through which the partition 5 enters and exits, thereby improving the sealing performance.

[0026] In some embodiments, the scraper 17 abuts against the inner wall of the electric furnace 1 on both sides, and there is a gap between the scraper 17 and the electric furnace 1 at both ends, so that the drive assembly can drive the scraper 17 to reciprocate.

[0027] In this embodiment, the gap between the two ends of the scraper 17 and the electric furnace 1 allows airflow to carry dust out through the exhaust pipe 8.

[0028] In some embodiments, the lead screw 11 is horizontally arranged, and the second slide 15 and the first slide 16 extend axially along the lead screw 11 so that the connecting rod 14 can move inside the second slide 15 and the first slide 16.

[0029] In the above structure, the electric furnace 1 can be opened and closed via the furnace door 2. During heating, the hydraulic cylinder 4 extends, causing the baffle 5 to cover the upper part of the electric furnace 1 to prevent heat leakage from the second sliding port 15. After heating, once the temperature has cooled, the hydraulic cylinder 4 retracts, causing the baffle 5 to retract from the electric furnace 1. Simultaneously, the baffle 5 rubs against the electric furnace 1, scraping the dust off the baffle 5 inside the electric furnace 1. At this time, airflow is introduced through the air supply device into the air inlet pipe 7, and then into the electric furnace 1 to blow away the dust. The airflow, carrying air, is discharged from the exhaust pipe 8 to the filtration device for filtration. To enhance dust removal, the linear drive assembly 9 is activated, driving the lifting bracket 10 to rise and fall. The rising and falling of the lifting bracket 10 synchronously drives the connecting rod 14 and scraper 17 to rise and fall, causing the linear drive assembly 9 to rub against the inner wall of the electric furnace 1, scraping away the dust adsorbed on the inner wall of the electric furnace 1. Simultaneously, the motor 12 is activated, driving the lead screw 11 to rotate. The lead screw 11 drives the slider 13 to reciprocate, which in turn drives the scraper 17 to move accordingly, causing the scraper 17 to rub against the bottom of the electric furnace 1, thus thoroughly cleaning the side walls and bottom of the electric furnace 1.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
