It can insulate and keep heat, prevent heat dissipation, separate the air, prevent oxidation of the molten steel surface, and purify the molten steel. The existing slag adding methods are manual or robotic addition. Manual addition will result in uneven slag thickness, affect the quality of the steel, and have high labor intensity. Robotic addition will significantly improve operating efficiency, ensure steel quality, and save labor costs.
[0003] There are many designs of single screw conveyor structures at present, but there are not many screw conveyors based on the continuous casting slag adding site environment and robot installation application. The technical defects are mainly reflected in:
[0004] 1. Many screw conveyors are made of ordinary steel, and the overall design structure is too heavy, which indirectly increases the load kilograms of the robot and increases the overall procurement cost.
[0005] 2. Some screw conveyors adopt the two-stage silo screw conveyor mode, which cannot achieve continuous slag addition. The screw conveyor needs to be moved to a fixed device to automatically replenish materials, which has a great impact on the on-site process. At the same time, due to leakage during the replenishment process, it also causes great pollution to the on-site environment.
[0006] 3. Some screw conveyors need to operate for a long time due to on-site production requirements. Some screw conveyors do not have wear-resistant materials added to the front end or do not have a segmented design in structure. When the front end of the equipment is worn, the entire screw barrel needs to be replaced, and the maintenance cost is high. Summary of the invention

In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited to the basic implementation disclosed below.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0026] like Figure 1-3 As shown, a continuous casting slag adding screw conveyor according to an embodiment of the utility model comprises a screw conveyor barrel 1, a support flange 2, a coupling housing 3, and a motor reducer counterweight sleeve 4 which are connected in sequence. Among them, the end of the screw conveyor barrel 1 is the discharge port end, the front end of the screw conveyor barrel 1 is connected to the end of the support flange 2, the front end of the support flange 2 is connected to the end of the coupling housing 3, and the front end of the coupling housing 3 is connected to the motor reducer counterweight sleeve 4. It is explained here that the front end is the end away from the discharge port direction of the screw conveyor barrel 1, and the end is the end close to the discharge port direction of the screw conveyor barrel 1.

[0028] The front end of the spiral conveyor barrel 1 is detachably connected with a feed section 11, and a feed port 12 is provided on the feed section 11, and the feed section 11 is connected to the end of the support flange 2. Among them, the feed port 12 is used to receive the unloading material, and it can realize automatic material replenishment by connecting with the unloading port or the unloading pipe, so as to facilitate the continuous slag adding operation. The feed section 11 can be detachably connected to the front end of the spiral conveyor barrel 1 by one or more of the following methods: threaded connection, clamp connection, snap connection, etc. During long-term operation, if the feed port is damaged due to factors such as high temperature, the feed section 11 can be disassembled and replaced without replacing the entire spiral barrel, and the maintenance cost is low. The length of the spiral conveyor barrel 1 can be determined according to the actual working conditions, and a longer length can be set. For example, the length of the spiral conveyor barrel 1 is 2m.
[0029] The spiral conveyor barrel 1 has a shaftless spiral blade 13, which extends to the feed port 12. The front end of the shaftless spiral blade 13 has a spiral shaft 14; the output shaft of the motor is connected to the spiral shaft 14. The operation of the motor drives the spiral shaft 14 to rotate, and the spiral shaft 14 drives the shaftless spiral blade 13 to rotate, so that the slag material is transported to the discharge port at the rear end of the spiral conveyor barrel 1 for slag addition. It is explained here that the shaftless spiral blade 13 of the spiral conveyor barrel 1 is only connected to a spiral short shaft at the front end, and the overall weight is relatively low, which can reduce the load of the slag adding robot.
[0030] The coupling housing 3 has a coupling 31, and the output shaft of the motor is connected to the screw shaft 14 through the coupling 31. Optionally, the coupling 31 is a top screw coupling, and of course, other forms of couplings can also be used, as long as the output shaft of the motor and the screw shaft 14 are stably connected.

[0033] Optionally, a seal is provided in the feed section 11, which is arranged at the front end of the feed section 11 corresponding to the screw shaft 14. The screw shaft 14 is connected to the output shaft through the seal. The seal is used to seal the screw shaft 14 to prevent slag from flowing out from the connection between the screw shaft 14 and the power transmission shaft during the feeding process, thereby avoiding leakage from polluting the on-site environment. At the same time, the seal can also fix the screw shaft 14 to ensure the stability of the screw shaft 14 during the feeding process.
[0034] In actual application scenarios, the motor, reducer, coupling, etc. in the continuous casting slag screw conveyor of the embodiment of the utility model can adopt devices with corresponding functions in the prior art. In addition, other devices or components can be set in the continuous casting slag screw conveyor, or the actual installation position of each device or component can be adjusted to realize the practical application or other functions of the continuous casting slag screw conveyor. For example, bearings 23 and fixed bearing components are set at both ends of the support flange 2, and the power transmission shaft of the equipment is fixedly supported by the supporting effect of the bearing to ensure the stability of equipment operation.
[0035] It should be pointed out that, according to the needs of implementation, the various components described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.
