Description

Technical Field

[0001] This utility model relates to the field of metallurgical technology, specifically to an iron front three-way distributor. Background Technology

[0002] Currently, during production in the ironmaking workshop of a steel plant, a three-way distributor is needed to divert upstream materials to the downstream conveyor belt for transportation. Most existing three-way distributors consist of a cylinder, a main valve plate, a rotating shaft, a rocker arm, and a push rod. The cylinder has an inlet at the top and two outlets symmetrically arranged at the bottom. The main valve plate is fixed inside the cylinder by the rotating shaft. The push rod drives the main valve plate and the rotating shaft to rotate as a whole through the rocker arm, realizing the opening and closing of the two outlets. During use, both sides of the main valve plate are alternately subjected to strong material flow impacts. Under the action of strong material flow impact force, the main valve plate of the three-way distributor is easily worn through, shortening its service life.

[0003] In addition, the material also has a certain impact and abrasion on the rotating shaft, and small-diameter materials are easy to get stuck between the main valve plate and the cylinder, making it impossible for the valve to open; the material falls directly from the discharge port to the conveyor belt at a high speed, which can easily cause intermittent dust and affect the production environment; the material after passing through the main valve plate flows directly out of the discharge port, which cannot guarantee that the conveyor belt will operate within the allowable "filling rate" requirement range, and is prone to "pipe bursting" accidents. Utility Model Content

[0004] The present invention aims to solve the above problems and thus provide a front tee feeder for iron.

[0005] The technical solution adopted by this utility model to solve the aforementioned problem is:

[0006] A front tee feeder for iron includes a cylindrical body, which is welded together from a vertical section and an inclined section. The inclined section is located to the side of the vertical section and communicates with it. The bottom ends of both the vertical and inclined sections are connected to right-angled bottom chutes. A discharge valve plate is hinged to the top of the discharge port of the bottom chutes, and a discharge valve plate cylinder is hinged to the back of the discharge valve plate. The discharge valve plate cylinder is fixed to the outer wall of the bottom chutes by a support frame, and the discharge valve plate cylinder is hinged to the support frame. A main valve plate is connected to the inside of the inclined section through a rotating shaft. A main valve plate cylinder that controls the rotation of the rotating shaft is provided on the outer wall of the cylindrical body. The push rod of the main valve plate cylinder drives the main valve plate and the rotating shaft to rotate as a whole through a rocker arm.

[0007] Furthermore, an anti-jamming plate is installed inside the inclined section cylinder and below the rotating shaft to prevent metallurgical materials from getting stuck between the main valve plate and the inner wall of the cylinder when the main valve plate closes the inclined section cylinder, thus preventing the main valve plate from being unable to open.

[0008] Furthermore, the discharge port of the bottom chute faces the same direction as the downstream conveyor belt; the material falls in the same direction as the belt, which greatly reduces the material impact speed (reduces kinetic energy impact), avoids sharp materials from scratching the belt, and reduces dust, thus improving the safety and environmental friendliness of the working environment.

[0009] Furthermore, small storage troughs are provided on the lower inner wall of the inclined section cylinder; the storage troughs can store a small amount of metallurgical material, thereby forming a wear-resistant layer on the inner wall of the inclined section cylinder, reducing the wear of the inclined section cylinder and extending the service life of the three-way distributor.

[0010] Furthermore, the main valve plate cylinder is fixed to the outer wall of the cylinder by a mounting seat, and the main valve plate cylinder and the mounting seat are hinged together.

[0011] Furthermore, a liner is installed inside the bottom chute, specifically at the corner position, to increase the service life of the bottom chute.

[0012] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are:

[0013] The rotating shaft and main valve plate of this invention are located inside the inclined section of the cylinder, which effectively reduces the direct impact of incoming material, reduces wear, and increases service life. Discharge valve plates are installed at the discharge ports; by controlling the opening and closing of these valves, the discharge rate is controlled, preventing pipe bursts caused by a large outflow of metallurgical material when there is excessive upstream material. The discharge port of the bottom chute faces the same direction as the downstream conveyor belt, and the material falls in the same direction as the belt, significantly reducing the material impact velocity (reducing kinetic energy impact), preventing sharp materials from scratching the belt, and reducing dust, thus improving the safety and environmental friendliness of the working environment. The anti-jamming plate prevents metallurgical material from getting stuck between the main valve plate and the inner wall of the cylinder when the main valve plate closes the inclined section, thus preventing the main valve plate from being unable to open.

[0017] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0018] See Figures 1-2 A front tee feeder for iron includes a cylindrical body 1, which is constructed by welding a vertical section and an inclined section. The inclined section is located to the side of the vertical section and is connected to the vertical section. The bottom ends of both the vertical section and the inclined section are connected to right-angled bottom chutes 4. A discharge valve plate 6 is hinged to the top of the discharge port of the bottom chutes 4. A discharge valve plate cylinder 8 is hinged to the back of the discharge valve plate 6. The discharge valve plate cylinder 8 is fixed to the outer wall of the bottom chutes 4 by a support frame 7. The discharge valve plate cylinder 8 is hinged to the support frame 7. A main valve plate 2 is connected to the inside of the inclined section by a rotating shaft. A wear-resistant layer 3 is provided on the surface of the main valve plate 2. A main valve plate cylinder 9 is provided on the outer wall of the cylindrical body 1 to control the rotation of the rotating shaft. The push rod of the main valve plate cylinder 9 drives the main valve plate 2 and the rotating shaft to rotate as a whole through a rocker arm 11.

[0019] Furthermore, an anti-jamming plate 12 is provided inside the inclined section cylinder 1 and below the rotating shaft; this prevents metallurgical materials from getting stuck between the main valve plate 2 and the inner wall of the cylinder 1 when the main valve plate 2 closes the inclined section cylinder, thus preventing the main valve plate 2 from being unable to open.

[0020] Furthermore, the discharge port of the bottom chute 4 faces the same direction as the downstream conveyor belt; the material falls in the same direction as the belt, which greatly reduces the material impact speed (reduces kinetic energy impact), avoids sharp materials from scratching the belt, and reduces dust, thus improving the safety and environmental friendliness of the working environment.

[0021] Furthermore, a small storage trough 13 is provided on the lower inner wall of the inclined section cylinder 1; the small storage trough 13 can store a small amount of metallurgical material, thereby forming a wear-resistant layer on the inner wall of the inclined section cylinder 1, reducing the wear of the inclined section cylinder 1, and extending the service life of the three-way distributor.

[0022] Furthermore, the main valve plate cylinder 9 is fixed to the outer wall of the cylinder 1 by the mounting seat 10, and the main valve plate cylinder 9 and the mounting seat 10 are hinged together.

[0023] Furthermore, a liner 5 is provided inside the bottom chute 4 and at the corner position to increase the service life of the bottom chute 4.

[0024] The rotating shaft and main valve plate of this invention are located inside the inclined section of the cylinder, which effectively reduces the direct impact of incoming material, reduces wear, and increases service life. Discharge valve plates are installed at the discharge ports; by controlling the opening and closing of these valves, the discharge rate is controlled, preventing pipe bursts caused by excessive upstream material flow. The discharge port of the bottom chute faces the same direction as the downstream conveyor belt, and the material falls in the same direction as the belt, significantly reducing the material impact velocity (reducing kinetic energy impact), preventing sharp materials from scratching the belt, and simultaneously reducing dust, thus improving the safety and environmental friendliness of the working environment.

All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
