Description

Technical Field

[0001] The utility model relates to the technical field of ore thermal furnace feeding, in particular to a feeding machine for metallurgical ore thermal furnace. Background Technique

[0002] The feeding machine for metallurgical ore thermal furnace, as a special feeding device inside the ore thermal furnace, its main design and structural goals are to improve production efficiency, reduce manual operation and reduce safety risks to operators.

[0003] However, the current feeding machine for metallurgical ore thermal furnace faces a significant problem in practical applications: the feeding tray is huge in volume, making it extremely difficult to fine-tune the angle. This dilemma mainly stems from the design and structural characteristics of the feeding tray.

[0004] Firstly, the feeding tray, as the core component of the feeding machine, is quite large in size and weight to meet the need of pushing a large amount of ore. However, while endowing the feeding tray with powerful feeding ability, this design also increases the challenge of fine-tuning the angle. Because the huge volume and weight mean that more energy and force are required to drive the feeding tray for a tiny angle adjustment during fine-tuning.

[0005] Secondly, the feeding tray usually adjusts the angle by the way of walking angle. This way may be applicable for large-scale adjustment, but it seems inadequate when precise fine-tuning is needed. The adjustment of walking angle relies on the driving device (such as motor, hydraulic cylinder, etc.) to push the feeding tray to move on the track to achieve, and this moving way is very difficult to accurately control the angle change of the feeding tray during fine-tuning.

[0006] Finally, the problem of difficult fine-tuning of the feeding tray angle may also have an adverse impact on the production efficiency of the ore thermal furnace. Because the angle of the feeding tray is directly related to the feeding effect of the ore. If the angle adjustment is improper, it may lead to problems such as uneven ore feeding and blockage, thus affecting the stable operation and overall efficiency of the ore thermal furnace. Content of the Utility Model

[0007] The main purpose of the utility model is to provide a feeding machine for metallurgical ore thermal furnace, which can effectively solve the problems put forward in the background technique.

[0008] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0009] A feeding machine for metallurgical ore thermal furnace, including a hydraulic device, a mounted counterweight, a sleeve, a push rod and a feeding tray. The mounted counterweight and the push rod are respectively located at both ends of the hydraulic device, the feeding tray is placed at the outer end of the push rod, and the sleeve is sleeved on the side wall of the hydraulic device.

[0010] The lower end of the sleeve is provided with an intermediate frame through an arc-shaped top frame. The outer end of the intermediate frame is sleeved with a support frame, and both sides of the support frame are connected with moving wheels through a transmission device, and the positions of the hydraulic device and the feeding tray are adjusted through the moving wheels.

[0011] Both ends inside the frame of the support frame are provided with side frames, and arc-shaped sliding grooves are opened at the upper ends of the side frames. A drill rod is inserted into the grooves of the arc-shaped sliding grooves, and the drill rod is fixed to the side frame through a nut. A fixing sleeve is sleeved on the rod body of the drill rod, and a telescopic rod is arranged on the side wall of the fixing sleeve. An arc-shaped block is arranged at the telescopic end of the telescopic rod. The drill rod moves along the arc-shaped sliding groove and presses against the push rod through the arc-shaped block, and the angle of the push rod is finely adjusted by using the drill rod and the arc-shaped block.

[0012] In a preferred embodiment of the present application, the arc-shaped top frame is divided into a telescopic round tube and an arc-shaped strip. The arc-shaped strip is placed at the upper end of the telescopic round tube. A blocking ring is arranged at the lower end of the telescopic round tube. The telescopic round tube and the blocking ring are inserted into the opening at the upper end of the intermediate frame, and the contact ends of the telescopic round tube and the blocking ring with the intermediate frame are designed to be smooth.

[0013] In a preferred embodiment of the present application, the two side frames are parallelly distributed at both ends of the intermediate frame. The arc-shaped sliding groove is designed in a "C" shape, and a rubber strip is adhered to the notch of the arc-shaped sliding groove.

[0014] In a preferred embodiment of the present application, the drill rod is divided into a drill bit, a screw rod and a hammer head. The drill bit and the hammer head are respectively located at both ends of the screw rod. The drill bit, the screw rod and the hammer head are integrally designed. A nut and an anti-slip gasket are sleeved on the rod body of the screw rod, and the drill rod is fixed to the side frame through the nut and the anti-slip gasket.

[0015] In a preferred embodiment of the present application, the fixing sleeve is sleeved on the drill rod and fixed to the drill rod by a nut. Rubber rings are arranged at both ends of the fixing sleeve. The telescopic rod is divided into a base tube and a threaded tube.

[0016] In a preferred embodiment of the present application, the arc-shaped block is fixed on the threaded tube of the telescopic rod, and an anti-slip rubber sheet is arranged on the inner wall of the arc-shaped block.

[0017] Compared with the prior art, the present utility model has the following beneficial effects:

[0018] In the present utility model, the pusher can quickly and accurately move to the designated position in front of the metallurgical furnace through the moving wheels and the transmission device inside it. This high degree of mobility ensures that it can adjust its position immediately according to actual needs, thereby significantly improving work efficiency. Furthermore, the pusher is equipped with an angle fine-tuning structure, and this design allows the angle of the feeding tray to be finely adjusted. This function is crucial for meeting the feeding requirements of diverse materials. By finely adjusting the angle of the push rod, the feeding tray can precisely control the feeding direction and speed of the materials, ensuring that the materials can enter the submerged arc furnace evenly and stably.

[0019] It is worth mentioning that the angle fine-tuning structure stably controls the angle of the push rod through the ingenious cooperation of the telescopic rod and the arc-shaped block. This design ensures that the adjusted angle is stable and reliable, not easily offset by external forces, thereby improving the stability and reliability of the pusher and effectively reducing the failure rate and maintenance cost.

[0020] Finally, the perfect cooperation between the traveling device and the angle fine-tuning structure makes the pusher perform more efficiently and stably in front of the metallurgical furnace. By precisely controlling the angle and position of the push plate, the pusher can efficiently push the materials into the submerged arc furnace, greatly improving the production efficiency. At the same time, this design also reduces the working difficulty and labor intensity of the operators and improves the overall work safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.

[0027] As Figure 1 - Figure 4 shown, in the metallurgical industry, the submerged arc furnace pusher is an indispensable equipment. This pusher has a unique design and includes multiple core components to ensure its efficient and stable operation. These components include a hydraulic device 1, a mounted counterweight 2, a sleeve 3, a push rod 4, a push plate 5 and a series of support and adjustment devices.

[0028] The hydraulic device 1 is the power source of this pusher, and its two ends are respectively connected to the mounted counterweight 2 and the push rod 4. The pusher plate 5 is located at the outer end of the push rod 4 and is used to directly push the material. The sleeve 3 is cleverly sleeved on the side wall of the hydraulic device 1, providing additional support and stability for the entire structure.

[0029] To achieve flexible adjustment of the position of the pusher, we designed a set of support and movement system. The lower end of the sleeve 3 is connected to the middle frame 9 through the arc top frame 10. The outer end of the middle frame 9 is sleeved with a support frame 6, and both sides of the support frame 6 are connected to the moving wheels 7 through the transmission device 8. These moving wheels 7 can easily move on various grounds, thus achieving precise adjustment of the positions of the hydraulic device 1 and the pusher plate 5.

[0030] To achieve fine adjustment of the angle of the push rod 4, we designed a unique angle fine adjustment system. At both ends inside the frame of the support frame 6, there are side frames 11. The upper ends of the side frames 11 are provided with arc-shaped chutes 12 in the shape of "C". A drill rod 13 is inserted into this chute. The drill rod 13 is fixed to the side frame 11 through nuts and anti-slip gaskets. A fixed sleeve 14 is sleeved on the rod body of the drill rod 13, and a telescopic rod 15 is provided on the side wall of the fixed sleeve 14. An arc-shaped block 16 is provided at the telescopic end of the telescopic rod 15. When the drill rod 13 moves along the arc-shaped chute 12, the arc-shaped block 16 will press against the push rod 4, thus achieving fine adjustment of the angle of the push rod 4.

[0031] The arc top frame 10 is composed of a telescopic round tube and an arc-shaped strip. A blocking ring is provided at the lower end of the telescopic round tube. Both of these parts are inserted into the openings at the upper end of the middle frame 9. To ensure smooth movement and stable connection, the contact ends of the telescopic round tube, the blocking ring and the middle frame 9 are all designed to be smooth.

[0032] The two side frames 11 are distributed in parallel at both ends of the middle frame 9, ensuring the stability of the entire structure. A rubber strip is adhered to the notch of the arc-shaped chute 12 to increase the smoothness and stability of the movement of the drill rod 13 in the chute.

[0033] The drill rod 13 is composed of a drill bit, a screw rod and a hammer head. These three parts are integrally designed. Nuts and anti-slip gaskets are sleeved on the rod body of the screw rod to ensure that the drill rod 13 is firmly fixed to the side frame 11. The fixed sleeve 14 is sleeved on the drill rod 13 and is fixed to the drill rod 13 by nuts. Rubber rings are provided at both ends of the fixed sleeve 14 to increase the friction with the drill rod 13. The telescopic rod 15 is composed of a base tube and a threaded tube. The base tube is integrally designed with the fixed sleeve 14, and the threaded tube is threadedly connected to the base tube, facilitating adjustment of the telescopic length. The arc-shaped block 16 is fixed on the threaded tube of the telescopic rod 15, and anti-slip rubber sheets are provided on its inner wall to ensure firm contact with the push rod 4.

[0034] Fine-tuning working process: The pusher of the metallurgical submerged arc furnace is preliminarily positioned in front of the metallurgical furnace through the moving wheels 7. The transmission device 8 drives the moving wheels 7 to move the whole pusher to the required position. The cooperation between the support frame 6 and the intermediate frame 9 ensures the stability of the pusher during movement.

[0035] The arc top frame 10 is connected to the intermediate frame 9 to provide a stable support for the pusher. The arc top frame 10 composed of telescopic round tubes and arc strips is tightly fitted with the opening of the intermediate frame 9 through the blocking ring to ensure stability and retractability.

[0036] The drill rod 13 is fixed in the "C"-shaped arc chute 12 of the side frame 11 through nuts and anti-slip gaskets. The rubber strip of the arc chute 12 increases the smoothness and stability of the movement of the drill rod 13.

[0037] Rotate the drill rod 13 to move it within the arc chute 12. The movement of the drill rod 13 drives the fixed sleeve 14 and the telescopic rod 15, so that the arc block 16 presses against the push rod 4. The base tube of the telescopic rod 15 is integrally designed with the fixed sleeve 14, and the threaded tube realizes the telescopic adjustment of the length through rotation. The anti-slip rubber sheet on the inner wall of the arc block 16 ensures a stable contact with the push rod 4 to achieve fine angle adjustment.

[0038] With the movement of the drill rod 13 and the telescopic movement of the telescopic rod 15, the angle of the push rod 4 is finely adjusted. After the angle is finely adjusted, the push plate 5 also changes the angle accordingly to better adapt to the requirements of different material pushing.

[0039] The operator observes the actual position and angle of the push plate 5 to confirm whether the predetermined requirements are met. If further fine-tuning is required, the above steps can be repeated until the best pushing effect is achieved. The angle adjustment device of the pusher of the metallurgical submerged arc furnace cooperates with the traveling device to achieve precise fine-tuning of the angle of the push plate 5, ensuring the efficient and stable operation of the pusher in front of the metallurgical furnace.
