Description

Technical Field

[0001] The utility model relates to the technical field of steel smelting, in particular to a mobile unloading device. Background Art

[0002] In the production process of steelmaking or ironmaking in the metallurgical industry, it is often necessary to add alloys, coke, steel chips and other materials at different feeding ports of the converter. The switching of feeding at different feeding ports is often achieved through flap valves. Flap valves work better for materials with low hardness and materials without impurities such as fine particles, such as lime, carbon powder and other materials. However, for materials with high hardness and containing impurities such as fine particles, such as alloys and steel chips, the materials often get stuck in the side gap of the flap, causing the flap to be stuck and the feeding port to be unable to be switched, resulting in the wrong material discharge, which ultimately causes a relatively large production accident and brings considerable losses to production.

[0003] In order to solve the above problems, many improvements have been made during the period. Various improvements have been made to the flap valve driving mode, from pneumatic drive to more powerful hydraulic drive, and the jamming situation has been slightly improved compared with before; but new problems have arisen. Due to the strong hydraulic driving force, the flap valve is forced to open. After multiple switches, the flap valve shaft and sleeve break and deform due to fatigue and other reasons. The production needs to be stopped for repair or replacement, resulting in production interruption and greatly reducing production efficiency; in addition, improvements such as appropriately increasing the side gap of the flap and adding a baffle above the side gap of the flap have not been able to completely solve the flap jamming problem. Utility Model Content

[0004] The purpose of the utility model is to provide a mobile unloading device to solve at least one aspect of the problems and defects raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A mobile unloading device is arranged above the first unloading port and the second unloading port of the converter, comprising:

[0007] A steel structure support, wherein a steel rail is arranged on the top of the steel structure support, and a mobile unloading vehicle is arranged on the steel rail;

[0008] The mobile unloading vehicle comprises a frame and wheels, and a unloading hopper is arranged in the middle of the frame;

[0009] A driving device is arranged on one side of the mobile unloading vehicle.

[0010] The mobile unloading device according to this solution has at least the following technical effects:

[0011] The mobile unloading device replaces the original flap valve that controls the switching of feeding at different unloading ports. Steel structure supports are arranged on the upper part of the first unloading port and the second unloading port of the converter, and rails are arranged on the top of the steel structure supports. A mobile unloading vehicle is arranged on the rails, and a unloading hopper is arranged in the middle of the frame. The mobile unloading vehicle is controlled by a driving device to switch back and forth between the first unloading port and the second unloading port of the converter. This solves the problem of adding different materials at different unloading ports and ensuring the smoothness of unloading, and effectively avoids the situation in which traditional flap valves easily cause materials to be stuck in the side gap, thereby causing the flap to be stuck and requiring shutdown for maintenance. The device effectively improves the working stability and continuity of unloading, and reduces equipment failure rate and maintenance costs.

[0012] As a further solution of the utility model: a plurality of rib plates are arranged on both sides of the discharge hopper, and the plurality of rib plates are connected to the vehicle frame.

[0013] Since the mobile unloading vehicle needs to switch back and forth between the first unloading port and the second unloading port of the converter to unload, during the moving and switching process, the material in the unloading hopper is thrown out due to inertia, causing the unloading hopper to shake or vibrate. By providing a number of rib plates on both sides of the unloading hopper, which are all connected to the frame, the stability of the unloading hopper is effectively improved, ensuring that the mobile unloading vehicle maintains the stability of the unloading hopper during switching.

[0014] As a further solution of the utility model: the inner wall of the discharge hopper is provided with a wear-resistant plate.

[0015] As a further solution of the utility model: the thickness of the wear-resistant plate is 25mm-35mm.

[0016] During the switching process of the mobile unloading vehicle, the material is thrown away due to the inertia of the material, which will cause wear on the inner wall of the unloading hopper, causing the inner wall of the unloading hopper to deform or be damaged. By providing a wear-resistant plate on the inner wall of the unloading hopper, the rigidity of the inner wall of the unloading hopper is effectively improved, thereby extending the service life of the unloading hopper.

[0017] As a further solution of the utility model: the wear-resistant plate is a ceramic lining plate.

[0018] Since the wear-resistant plate is a ceramic lining plate, it has excellent wear resistance and can more effectively resist the friction and wear of the material, thereby improving the durability and reliability of the discharge hopper and further extending the service life of the discharge hopper.

[0019] As a further solution of the utility model: the driving device is driven by a cylinder.

[0020] Since the driving device is driven by a cylinder, the cylinder is controlled by compressed air to drive the mobile unloading vehicle to move back and forth on the rails. The mobile unloading vehicle is switched at the upper part of the first unloading port and the second unloading port, so that unloading can be carried out at the first unloading port and the second unloading port respectively, thereby improving the operability and flexibility of unloading.

[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0032] like Figure 1 and Figure 2 The embodiment of the utility model shown is a mobile unloading device, which is arranged on the upper part of the first unloading port 1 and the second unloading port 2 of the converter, including: a steel structure support 3, a steel rail 4 is arranged on the top of the steel structure support 3, and a mobile unloading vehicle 5 is arranged on the steel rail 4; the mobile unloading vehicle 5 includes a frame 501 and wheels 502, and a unloading hopper 503 is arranged in the middle of the frame 501; a driving device 6 is arranged on one side of the mobile unloading vehicle 5.

[0033] Specifically, the mobile unloading device replaces the original flap valve that controls the switching of feeding at different unloading ports, by arranging a steel structure support 3 on the upper part of the first unloading port 1 and the second unloading port 2 of the converter, and arranging a rail 4 on the top of the steel structure support 3, a mobile unloading vehicle 5 on the rail 4, and a unloading hopper 503 in the middle of the vehicle frame 501, and controlling the mobile unloading vehicle 5 to switch back and forth between the first unloading port 1 and the second unloading port 2 of the converter by a driving device 6, thereby solving the problem of adding different materials at different unloading ports and ensuring the smoothness of unloading, and effectively avoiding the situation in which the traditional flap valve easily causes the material to be stuck in the side gap, thereby causing the flap to be stuck and the need to shut down for maintenance, the device effectively improves the working stability and continuity of unloading, and reduces the equipment failure rate and maintenance cost.

[0034] like Figure 1 As shown, a plurality of ribs 504 are provided on both sides of the discharge hopper 503 , and the plurality of ribs 504 are all connected to the vehicle frame 501 .

[0035] Specifically, since the mobile unloading vehicle 5 needs to switch back and forth between the first unloading port 1 and the second unloading port 2 of the converter to unload, during the moving and switching process, the material in the unloading hopper 503 is thrown off due to inertia, causing the unloading hopper 503 to shake or vibrate. By providing a plurality of rib plates 504 on both sides of the unloading hopper 503, and the plurality of rib plates 504 are connected to the frame 501, the stability of the unloading hopper 503 is effectively improved, ensuring that the mobile unloading vehicle 5 maintains the stability of the unloading hopper 503 when switching.

[0036] like Figure 1 As shown, the inner wall of the discharge hopper 503 is provided with a wear-resistant plate 505; the thickness of the wear-resistant plate 505 is 25mm-35mm.

[0037] Specifically, during the switching process of the mobile unloading vehicle 5, the inertia of the material causes the material to be thrown off, which will cause wear on the inner wall of the unloading hopper 503, causing the inner wall of the unloading hopper 503 to deform or be damaged. By providing a wear-resistant plate 505 on the inner wall of the unloading hopper 503, the rigidity of the inner wall of the unloading hopper 503 is effectively improved, and the service life of the unloading hopper 503 is extended.

[0038] Furthermore, the wear-resistant plate 505 is a ceramic lining plate.

[0039] Specifically, since the wear-resistant plate 505 is a ceramic lining plate, it has excellent wear resistance and can more effectively resist the friction and wear of materials, thereby improving the durability and reliability of the discharge hopper 503 and further extending the service life of the discharge hopper 503.

[0040] like Figure 1 As shown, the driving device 6 is a cylinder drive.

[0041] Specifically, since the driving device 6 is driven by a cylinder, the cylinder is controlled by compressed air to drive the mobile unloading vehicle 5 to travel back and forth on the rail 4, and the mobile unloading vehicle 5 is switched at the upper part of the first unloading port 1 and the second unloading port 2, so that unloading can be carried out at the first unloading port 1 and the second unloading port 2 respectively, thereby improving the operability and flexibility of unloading.
