Description

Technical Field

[0001] This utility model relates to the field of grain-oriented silicon steel production technology, specifically to a protective gas supply structure for a grain-oriented silicon steel heating cover. Background Technology

[0002] The protective gas supply structure for the heating hood of grain-oriented silicon steel is a key facility serving the production of grain-oriented silicon steel. Starting from a gas source, it connects to the heating hood through gas supply pipelines. Using simple control methods, inert protective gases such as nitrogen are stably delivered to the heating hood, creating an air-isolated environment during the silicon steel heating process. This prevents the silicon steel from contacting oxygen, effectively solving the problems of silicon steel oxidation and decarburization. This provides a fundamental guarantee for producing grain-oriented silicon steel with excellent electromagnetic properties and high surface quality. At the same time, when supplying gas to existing equipment, impurities and moisture in the gas are filtered and removed to prevent them from contaminating the silicon steel sheets or affecting the protective effect.

[0003] In the existing protective gas supply structure of the oriented silicon steel heating hood, although a filter screen is provided to remove impurities and moisture from the gas to ensure that the silicon steel sheet is not contaminated and to maintain a good protective effect, the filter screen is fixed and the gas flows through the filter screen in one place for a long time. The part of the gas that flows through the filter screen is prone to blockage. Once blockage occurs, the gas flow rate will decrease and the stability of the gas supply will be greatly reduced. This will not only affect the creation of the protective atmosphere in the heating hood, but may also cause oxidation and decarburization of the silicon steel in some areas due to insufficient protective gas, which seriously threatens the product quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a protective gas supply structure for an oriented silicon steel heating cover, which has the advantages of filtering water and preventing blockage. It solves the problem mentioned in the background technology that impurities tend to accumulate on the filter screen surface during filtration, and once blockage occurs, the gas flow rate will decrease.

[0005] To achieve the aforementioned purpose of filtration, water removal, and clogging prevention, this utility model provides the following technical solution: It includes a heating cover, a connecting pipe fixedly connected to one bottom side of the heating cover, a filter box installed on the side of the connecting pipe away from the heating cover, an installation plate one fixedly connected to one side of the inner cavity of the filter box, an annular filter screen rotatably connected through the middle of the installation plate one, rotating rings one fixedly connected to both outer walls of the annular filter screen, and rotating rings one rotatably connected to the installation plate one, a toothed ring one fixedly connected through the middle of the outer wall of one rotating ring one, a connecting groove one opened at the bottom of one side of the installation plate one, a uniformly distributed sliding rod fixedly connected to the inner cavity of the connecting groove one, a shovel plate slidably connected to the outer wall of the sliding rod, and the side of the shovel plate away from the connecting groove one fitting against the annular filter screen, a tension spring sleeved on the outer wall of the sliding rod, and one side of the tension spring fixedly connected to the shovel plate, and an installation plate two fixedly connected to the inner cavity of the filter box away from the installation plate one, an annular sponge filter screen rotatably connected through the middle of the installation plate two.

[0006] As a further improvement of this utility model: both outer walls of the annular sponge filter are fixedly connected with rotating rings two, and rotating rings two are rotatably connected to mounting plate two. A toothed ring two is fixedly connected through the middle of the outer wall of one rotating ring two.

[0007] As a further embodiment of this utility model: a connecting groove 2 is provided on one side of the bottom of the mounting plate 2, and swing rods are rotatably connected to both sides of the inner cavity of the connecting groove 2. A squeezing roller is rotatably connected between the two swing rods, and the squeezing roller abuts against the outer wall of the annular sponge filter screen. A connecting plate is fixedly connected to the left and right sides of the bottom of the mounting plate 2 near the connecting groove 2, and a spring is fixedly connected to the top of the connecting plate. The end of the spring away from the connecting plate is fixedly connected to the swing rod.

[0008] As a further improvement of this utility model, a flange connecting pipe is connected through and fixedly connected to the outer wall of the filter box on the side away from the connecting pipe.

[0009] As a further improvement of this utility model: a second collection box is installed through and on one side of the bottom of the filter box, and the second collection box is located at the bottom of the shovel plate.

[0010] As a further improvement of this utility model: a collection box is installed through the bottom of the filter box on the side away from the second collection box, and the first collection box is located at the bottom of the extrusion roller.

[0011] As a further embodiment of this utility model: a motor is installed on one side of the outer wall of the filter box, and the output end of the motor passes through the filter box and is fixedly connected to a gear. Both sides of the outer wall of the gear are meshed with gear ring one and gear ring two.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, after the motor starts, the drive gear rotates, which in turn drives a series of linked components, causing rotating ring one and rotating ring two to rotate slowly. The annular filter screen and the annular sponge filter screen rotate accordingly. The rotation of the annular filter screen cleverly resolves the impact of airflow on a single location. Filtration is no longer limited to a local area, but spreads out evenly and efficiently, greatly improving the interception ability of dust and impurities. At the same time, the shovel plate, under the action of the tension spring, adheres tightly to the annular filter screen, removing dust from the annular filter screen and preventing the filter screen from becoming clogged over a long period of time. On the other hand, when the annular sponge filter screen rotates, the adsorbed moisture is squeezed out by the squeezing action of the swing rod and the squeezing roller under the spring force. The moisture falls directly into the collection box one, effectively preventing moisture accumulation that leads to filter screen clogging, maintaining good filtration performance, ensuring stable system operation, and providing stable energy supply for subsequent processes.

[0020] 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.

[0021] Please see Figures 1-5In this embodiment of the utility model, the protective gas supply structure for the oriented silicon steel heating cover includes a heating cover 1. A connecting pipe 2 is fixedly connected to the bottom of one side of the heating cover 1. A filter box 3 is installed on the side of the connecting pipe 2 away from the heating cover 1. A mounting plate 4 is fixedly connected to one side of the inner cavity of the filter box 3. An annular filter screen 5 is rotatably connected through the middle of the mounting plate 4. Rotating rings 6 are fixedly connected to both outer walls of the annular filter screen 5, and the rotating rings 6 are rotatably connected to the mounting plate 4. A toothed ring 7 is fixedly connected through the middle of the outer wall of one rotating ring 6. A connecting groove 14 is provided at the bottom of one side of the mounting plate 4. Evenly distributed sliding rods 15 are fixedly connected to the inner cavity of the connecting groove 14. A shovel plate 17 is slidably connected to the outer wall of the slide rod 15, and the side of the shovel plate 17 away from the connecting groove 14 is in contact with the annular filter screen 5. A tension spring 16 is sleeved on the outer wall of the slide rod 15, and one side of the tension spring 16 is fixedly connected to the shovel plate 17. The rotation of the annular filter screen 5 has many effects. On the one hand, it avoids the continuous impact of airflow on a fixed position of the filter screen when it rushes in from the flange connecting pipe 23, making the filtration process more uniform and efficient. On the other hand, during the rotation of the annular filter screen 5, the shovel plate 17 is always in close contact with the surface of the annular filter screen 5 under the elastic tension of the tension spring 16, and gently scrapes off the dust attached to the screen after filtration. This dust then falls into the collection box 25.

[0022] A mounting plate 8 is fixedly connected to the inner cavity of filter box 3 on the side away from mounting plate 4. An annular sponge filter screen 9 is rotatably connected through the middle of mounting plate 8. Rotating rings 10 are fixedly connected to both outer walls of the annular sponge filter screen 9, and the rotating rings 10 are rotatably connected to mounting plate 8. A toothed ring 11 is fixedly connected through the middle of the outer wall of one rotating ring 10. A connecting groove 18 is opened on one side of the bottom of mounting plate 8. Swing rods 19 are rotatably connected to both sides of the inner cavity of the connecting groove 18. A squeezing roller 20 is rotatably connected between the two swing rods 19, and the squeezing roller 20 abuts against the outer wall of the annular sponge filter screen 9. The bottom of the mounting plate 28 is fixedly connected to the left and right sides of the side near the connecting groove 218. The top of the connecting plate 21 is fixedly connected to the spring 22, and the end of the spring 22 away from the connecting plate 21 is fixedly connected to the swing rod 19. During the process of absorbing moisture, as the annular sponge filter 9 rotates, the swing rod 19 and the squeezing roller 20, with the elastic force of the spring 22, press tightly against the sponge part of the annular sponge filter 9, squeezing out the absorbed water. The squeezed water falls directly into the collection box 24 under the action of gravity, realizing the centralized collection of water.

[0023] A flange connecting pipe 23 is connected and fixedly connected to the outer wall of the filter box 3 on the side away from the connecting pipe 2. A collection box 25 is installed and connected to the bottom side of the filter box 3, and the collection box 25 is located at the bottom of the shovel plate 17. A collection box 24 is installed and connected to the bottom side of the filter box 3 away from the collection box 25, and the collection box 24 is located at the bottom of the extrusion roller 20. A motor 12 is installed on one side of the outer wall of the filter box 3. The output end of the motor 12 passes through the filter box 3 and is fixedly connected to a gear 13. Both sides of the outer wall of the gear 13 are meshed with a gear ring 7 and a gear ring 11. When the airflow enters the filter box 3 through the flange connecting pipe 23, the motor 12 starts synchronously and drives the gear 13 to rotate at high speed. Due to the operation of the motor 12, the gear ring 7 meshes tightly with the connecting pipe 2, and the gear ring 11 is also linked, thereby driving the rotating ring 6 and the rotating ring 10 to rotate slowly. The rotating ring 6 carries the annular filter screen 5 to rotate continuously, and the rotating ring 10 drives the annular sponge filter screen 9 to rotate together.

[0024] The working principle of this utility model is as follows: First, the flange connecting pipe 23 is connected to the air supply device. At this time, the airflow will flow into the filter box 3 along the pipe. As soon as it enters the filter box 3, the airflow first encounters the annular filter screen 5, which effectively intercepts the dust and impurities carried in the airflow and completes the initial filtration. Then, the airflow that has been initially purified continues to move forward and comes to the annular sponge filter screen 9. This special filter screen uses the adsorption properties of sponge to firmly lock the moisture in the airflow, so that the airflow is further purified. Finally, the pure airflow smoothly enters the heating cover 1 through the connecting pipe 2.

[0025] As the airflow enters the filter box 3 through the flange connecting pipe 23, the motor 12 starts synchronously, driving the gear 13 to rotate at high speed. Due to the operation of the motor 12, the gear ring 7 meshes tightly with the connecting pipe 2, and the gear ring 11 also moves in tandem, thereby driving the rotating ring 6 and rotating ring 10 to rotate slowly. The rotating ring 6 carries the annular filter screen 5 to rotate continuously, while the rotating ring 10 drives the annular sponge filter screen 9 to rotate together. The rotation of the annular filter screen 5 has many effects. On the one hand, it avoids the continuous impact of the airflow on a fixed position of the filter screen when it rushes in from the flange connecting pipe 23, making the filtration process more uniform and efficient. On the other hand, during the rotation of the annular filter screen 5, the scraper plate 17, under the elastic tension of the tension spring 16, always sticks to the surface of the annular filter screen 5, gently scraping off the dust attached to the screen after filtration. This dust then falls into the collection box 25 for unified treatment.

[0026] Meanwhile, as the sponge on the annular sponge filter 9 absorbs moisture, the swing rod 19 and the squeezing roller 20, with the help of the spring force of the spring 22, press tightly against the sponge part of the annular sponge filter 9, squeezing out the absorbed water. This squeezed-out water falls directly into the collection box 24 under the action of gravity, realizing the centralized collection of water and ensuring that the entire filtration system always maintains a good working condition.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
