Description

Technical Field

[0001] This utility model relates to the field of furnace tamping machine technology, specifically a furnace tamping machine that can clean up splashed furnace material. Background Technology

[0002] The furnace tamping machine is a special equipment used in the smelting industry (such as the production of ferroalloys, industrial silicon, and calcium carbide). Its main functions are to compact the furnace charge, break up the hard shell on the material surface, distribute the material evenly, prevent the material from forming a crust and hanging in the furnace, and ensure the stable operation of the electric furnace.

[0003] When the tamping machine inserts the tamping rod into the smelting furnace to tamp the furnace charge, the tamping car breaks up the materials (such as ore, coke, etc.) in the furnace through the reciprocating motion of the tamping rod. When the tamping rod impacts the material with a large force, small pieces of material may be splashed out of the furnace opening due to inertia. Especially when the material in the furnace is severely agglomerated or there are cavities, the impact force is more likely to cause the material to break up, splash, and accumulate at the furnace opening. Therefore, we propose a tamping machine that can clean up the splashed furnace charge to solve this defect of the existing technology. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a furnace tamping machine that can clean up spilled furnace materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a furnace tamping machine for cleaning splashed furnace materials, including a forklift body, a pair of hydraulic push rods on the right side of the forklift body, a mast hinged to the other end of the hydraulic push rods, the lower end of the mast hinged to the forklift body, a tamping rod on the mast, a pair of heat-insulating mounting seats at the lower end of the tamping rod, a guide rod between the heat-insulating mounting seats, a sliding seat on the guide rod, and a pushing component on the heat-insulating mounting seat to move the sliding seat;

[0006] The sliding base is equipped with a vertical lifting and rotating lifting assembly;

[0007] The rotary lifting assembly is equipped with a bucket. A pair of electric push rods are provided on opposite sides of the bucket opening. An electric guide rail is provided at the push rod of the electric push rod. A sliding hollow seat is provided at the guide rail slide of the electric guide rail. A scraper that slides up and down is provided on the sliding hollow seat. An elastic telescopic assembly is provided between the scraper and the sliding hollow seat.

[0008] Using the above technical solution, the forklift body drives the tamping rod to extend into the smelting furnace from the furnace opening. The tamping rod is moved up and down by the gantry, and the hydraulic push rod pushes the gantry to rotate and change the angle. This allows the tamping rod to tamp the material in the smelting furnace in conjunction with the movement of the forklift body. After tamping, the tamping rod is adjusted to be horizontal to the ground. The electric push rod pushes the electric guide rail, sliding hollow seat and scraper to move synchronously. The scraper moves in the opposite direction to the periphery of the splashed and accumulated material. Then, the rotating lifting component on the sliding seat moves the bucket down, so that the bottom of the bucket and the bottom of the scraper are in contact with the ground. At the same time, the electric guide rail moves the scraper on the sliding hollow seat to the front side of the bucket opening. After contact is completed, the electric push rod drives the scraper to move synchronously in opposite directions. With the elastic extension and contraction of the elastic extension component, the scraper always moves in contact with the ground, scraping the accumulated material on the ground to the middle of the front side of the bucket opening, until the scraper is in contact with the side of the bucket.

[0009] After the accumulated material is scraped to the middle, the electric guide rail moves the scraper back to the rear side of the bucket opening. Then, with the help of the pusher, the sliding seat moves on the guide rod, causing the bucket to move along the ground until it contacts the edge of the furnace opening. This allows the concentrated furnace material on the ground to be shoveled into the bucket. After collection, the bucket moves upward and, with the help of the rotating lifting component, rotates the bucket, causing the bucket opening to tilt upward, facilitating the transfer of furnace material in the bucket. After the transfer, the bucket rotates again, causing the bucket opening to tilt downward, thus unloading and dumping the stored furnace material. This effectively handles the furnace material that splashes and accumulates at the furnace opening.

[0010] As a preferred embodiment of this utility model, the pushing component is a hydraulic push rod II, which is mounted on the heat insulation mounting base on the left side. The hydraulic push rod II is connected to the sliding seat and pushes the sliding seat to move towards the other end of the tamping rod.

[0011] Using the above technical solution, the hydraulic push rod 2 pushes the sliding seat to move back and forth on the guide rod in a directional manner.

[0012] As a preferred technical solution of this utility model, the rotary lifting assembly includes a slide groove disposed on the front and rear sides of the sliding seat, an L-shaped seat sliding in the slide groove, an electric push rod two on the sliding seat, the push rod of the electric push rod two being connected to one of the L-shaped seats, a drive motor being disposed on the surface of one of the L-shaped seats, and a rotating shaft being disposed at the output end of the drive motor being connected to and rotating with the other L-shaped seat, the rotating shaft being connected to the bucket.

[0013] Using the above technical solution, the electric push rod 2 pushes the L-shaped seat to move up and down in the slide groove, so that the bucket moves up and down synchronously, and at the same time the drive motor drives the bucket to rotate.

[0014] As a preferred embodiment of this invention, the opening of the bucket faces the other end of the tamping rod.

[0015] As a preferred embodiment of this utility model, the scraper is parallel to the bottom of the bucket, and the elastic telescopic component includes a connecting rod disposed outside the sliding hollow seat and parallel to the scraper, a telescopic rod is provided between the connecting rod and the scraper, and a telescopic spring is provided between the connecting rod and the scraper, with the telescopic spring located outside the telescopic rod.

[0016] In a preferred embodiment of this utility model, when both the telescopic rod and the telescopic spring are in the extended state, the lower surface of the scraper is lower than the lower surface of the bucket; when both the telescopic rod and the telescopic spring are in the fully retracted state, the lower surface of the scraper is higher than the lower surface of the bucket.

[0017] By adopting the above technical solution, the extension and retraction of the telescopic rod and the elastic extension and retraction of the telescopic spring enable the scraper to adaptively conform to the ground and move.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] This furnace tamping machine, capable of cleaning splashed furnace materials, uses a forklift to drive the tamping rod, which extends from the furnace opening into the smelting furnace. The tamping rod moves up and down via the gantry, and a hydraulic pusher rotates the gantry to change its angle. This, combined with the movement of the forklift, allows the tamping rod to tamp the materials inside the smelting furnace. After tamping, the tamping rod is adjusted to be horizontal to the ground. An electric pusher then moves the electric guide rail, sliding hollow seat, and scraper synchronously. The scraper moves in the opposite direction to the periphery of the splashed material. Then, the rotating lifting component on the sliding seat moves the bucket down, bringing the bottom of the bucket and the bottom of the scraper into contact with the ground. Simultaneously, the electric guide rail moves the scraper on the sliding hollow seat to the front of the bucket opening. After contact is achieved, the electric pusher moves the scraper synchronously in opposite directions. With the elastic extension and retraction of the elastic extension component, the scraper remains in contact with the ground, scraping the accumulated material to the middle of the front side of the bucket opening until the scraper is in contact with the side of the bucket.

[0020] After the accumulated material is scraped to the middle, the electric guide rail moves the scraper back to the rear side of the bucket opening. Then, with the help of the pusher, the sliding seat moves on the guide rod, causing the bucket to move along the ground until it contacts the edge of the furnace opening. This allows the concentrated furnace material on the ground to be shoveled into the bucket. After collection, the bucket moves upward and, with the help of the rotating lifting component, rotates the bucket, causing the bucket opening to tilt upward, facilitating the transfer of furnace material in the bucket. After the transfer, the bucket rotates again, causing the bucket opening to tilt downward, thus unloading and dumping the stored furnace material. This effectively handles the furnace material that splashes and accumulates at the furnace opening. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] Please see Figures 1 to 4 The furnace tamping machine in this embodiment, which can clean up splashed furnace material, mainly includes a forklift body 1, a hydraulic push rod 2, a mast 3, a tamping rod 4, a heat-insulating mounting base 5, a guide rod 6, a sliding seat 7, a pushing component, a rotating lifting assembly, a bucket 12, an electric push rod 13, an electric guide rail 14, a sliding hollow seat 15, a scraper 16, and an elastic telescopic assembly, etc.

[0028] The forklift body 1 serves as the foundation for the movement and support of the entire equipment. A pair of hydraulic push rods 1-2 are hinged to its right side surface. A mast 3 is hinged between the push rods of the hydraulic push rods 1-2. The lower end of the mast 3 is hinged to the forklift body 1 and rotates. The extension and retraction of the hydraulic push rods 1-2 can push the mast 3 to rotate, thereby changing the angle of the tamping rod 4. A hydraulic cylinder is mounted on the mast 3. The tamping rod 4 is fixed at the push rod of the hydraulic cylinder. The hydraulic cylinder drives the tamping rod 4 to move vertically up and down. The tamping rod 4 is used to extend into the smelting furnace to tamp the furnace charge.

[0029] The lower end surface of the tamping rod 4 is detachably fixed with a pair of symmetrically distributed heat-insulating mounting seats 5 by bolts. The heat-insulating mounting seats 5 are made of high-temperature resistant and heat-insulating materials, such as ceramic fiber composite materials. Their function is to prevent the heat conducted by the tamping rod 4 in the high-temperature environment from damaging other components. A guide rod 6 is fixed between the heat-insulating mounting seats 5. The guide rod 6 is a high-strength, wear-resistant metal rod, such as a stainless steel rod. Its surface is smoothed to reduce the friction when the sliding seat 7 moves. The sliding seat 7 slides on the outside of the guide rod 6 and can slide freely on the guide rod 6.

[0030] The heat insulation mounting base 5 is provided with a pushing component that moves the sliding seat 7. In this embodiment, the pushing component is a hydraulic push rod 28. The hydraulic push rod 28 is fixed on the left side of the heat insulation mounting base 5 on the left side. The piston rod of the hydraulic push rod 28 is connected to and fixed to the sliding seat 7. When the hydraulic push rod 28 is working, its piston rod extends or retracts, thereby pushing the sliding seat 7 to move or pull back to the other end of the tamping rod 4. The hydraulic push rod 28 is controlled by a high-precision and high-reliability hydraulic system to ensure the accuracy and stability of its operation.

[0031] The sliding seat 7 is equipped with a vertical lifting and rotating component. The rotating lifting component includes a groove 9 opened on the front and rear side surfaces of the sliding seat 7. The groove 9 is smooth to ensure the smooth sliding of the L-shaped seat 10. The L-shaped seat 10 slides in the groove 9. The L-shaped seat 10 is made of high-strength aluminum alloy material and has the characteristics of light weight and high strength.

[0032] An electric push rod 11 is fixed on the sliding seat 7. The push rod of the electric push rod 11 is connected and fixed to the L-shaped seat 10 on the front side. When the electric push rod 11 is working, its push rod extends or retracts, driving the L-shaped seat 10 to move up and down in the sliding groove 9, thereby realizing the vertical lifting of the bucket 12.

[0033] A drive motor 19 is fixed on the surface of the front L-shaped base 10. The drive motor 19 is a high-performance servo motor with high speed, large torque and high control precision. The output end of the drive motor 19 is fixed with a rotating shaft that is connected to and rotates with the rear L-shaped base 10. The rotating shaft is made of high-strength and wear-resistant alloy steel. The rotating shaft passes through the bucket 12 and is fixed to it. When the drive motor 19 is working, its output end drives the rotating shaft to rotate, thereby causing the bucket 12 to rotate around the rotating shaft and realize the angle adjustment of the bucket 12.

[0034] The rotating lifting assembly is equipped with a bucket 12, which is welded from high-strength, wear-resistant steel plates. Its opening faces the right side of the tamping rod 4 to facilitate the collection of furnace material splashed onto the furnace mouth. A pair of electric push rods 13 are fixed on the opposite side of the opening of the bucket 12. The electric push rods 13 are linear electric push rods with the characteristics of large thrust and long stroke.

[0035] An electric guide rail 14 is fixed to the push rod of the electric push rod 13. The electric guide rail 14 is a linear guide rail. Its guide rail adopts a high-precision and wear-resistant ball guide rail. The slider slides smoothly on the guide rail with low friction. A sliding hollow seat 15 is fixed to the guide rail slide of the electric guide rail 14. The sliding hollow seat 15 can slide freely on the electric guide rail 14.

[0036] The bottom of the sliding hollow seat 15 has a scraper 16 that slides up and down. The scraper 16 is made of high-strength, wear-resistant rubber material. Its surface has been specially treated and has good elasticity and wear resistance. The scraper 16 is parallel to the bottom of the bucket 12 so as to scrape the furnace material accumulated on the ground to the front side of the opening of the bucket 12.

[0037] An elastic telescopic assembly is provided between the scraper 16 and the sliding hollow seat 15. The elastic telescopic assembly includes a connecting rod 17 fixed to the outside of the sliding hollow seat 15 and parallel to the scraper 16. The connecting rod 17 is made of high-strength aluminum alloy. A telescopic rod is fixed between the connecting rod 17 and the scraper 16. The telescopic rod is a metal rod with an adjustable length and its surface is rust-proofed. A telescopic spring 18 is also fixed between the connecting rod 17 and the scraper 16. The telescopic spring 18 is made of high-strength, fatigue-resistant spring steel and is located outside the telescopic rod.

[0038] When both the telescopic rod and the telescopic spring 18 are extended, the lower surface of the scraper 16 is lower than the lower surface of the bucket 12, which ensures that the scraper 16 can make full contact with the ground and scrape up the furnace charge accumulated on the ground. When both the telescopic rod and the telescopic spring 18 are fully retracted, the lower surface of the scraper 16 is higher than the lower surface of the bucket 12, so that the bucket 12 is not disturbed by the scraper 16 during movement.

[0039] The furnace tamping machine, which can clean up splashed furnace material, is controlled by an advanced PLC control system. The PLC control system controls the operation of components such as hydraulic push rod 12, hydraulic push rod 28, electric push rod 13, electric push rod 21, drive motor 19, and electric guide rail 14 according to the preset program.

After the transfer, control the drive motor 19 to work in reverse, so that the bucket 12 rotates and the opening of the bucket 12 tilts downward, so as to unload and dump the stored furnace charge.

[0050] Beneficial effects

[0051] The furnace tamping machine, capable of cleaning splashed furnace charge, effectively handles the furnace charge that has accumulated at the furnace mouth through the aforementioned structure and working principle. During the tamping process, the hydraulic push rod 2 and the gantry 3 work together to achieve multi-angle and multi-position tamping by the tamping rod 4, improving the tamping effect. When cleaning splashed furnace charge, the electric push rod 13, electric guide rail 14, scraper 16, and rotary lifting assembly work together to accurately scrape the furnace charge accumulated on the ground into the bucket 12. The collection, transfer, and unloading of furnace charge are achieved through the rotation and movement of the bucket 12. At the same time, the design of the elastic telescopic assembly allows the scraper 16 to adapt to the ground and move, improving the cleaning effect. In addition, the use of a PLC control system enables automated operation of the equipment, improving work efficiency and operational accuracy.
