Description

Technical Field

[0001] This utility model relates to the field of copper converter technology, and in particular to a copper converter air supply device. Background Technology

[0002] Copper converters are widely used in the metallurgical industry, mainly to convert copper concentrate or matte into pure copper or blister copper. They typically consist of a blast furnace drum and a combustion chamber. By melting the raw materials at high temperatures, the copper is separated out for subsequent processing.

[0003] Air supply is crucial in the copper converter smelting process. It's key to the continuous smelting reaction because the oxygen in the air reacts with the sulfur and iron in the copper matte, generating heat to sustain the entire smelting process. Simultaneously, it removes impurities, improving copper purity. Furthermore, by rationally controlling the air supply, reaction conditions can be optimized, improving production efficiency and product quality. When supplying air into the copper converter through its internal ducts, it needs to be coordinated with external air supply devices such as blowers. However, due to the operating environment of the copper converter, the ore and other media generate a large amount of dust. Therefore, even with filters at the air inlet of the blowers, some fine dust still enters the blower and accumulates on the blade surface. This dust not only reduces blower efficiency and airflow channels, affecting the copper converter's air supply effect, but also accelerates blade wear and corrosion, shortening the equipment's lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a copper converter air supply device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A copper converter air supply device includes a converter body, a base, and an air supply mechanism. Two sets of supporting mechanisms are fixedly installed on the base. Two wheel rings are fixedly installed on the outer side of the converter body, and the converter body is movably mounted on the two sets of supporting mechanisms via the two wheel rings. The air supply mechanism includes a frame, a fan housing, and a motor. The fan housing and motor are respectively fixedly installed on the frame. A pulley is fixedly installed at the output end of the motor, and the motor is electrically connected to an external main controller via a connecting wire. A supporting tripod is fixedly installed on the rear side of the frame, and an electric telescopic device is fixedly installed on the supporting tripod. The electric telescopic device is electrically connected to an external main controller via a connecting wire. A telescopic rod is movably installed inside the telescopic device. Multiple T-shaped top blocks are movably installed at one end of the telescopic rod. An air inlet is opened on the front side of the fan casing. A dust cover is fixedly installed on the front side of the air inlet. An air outlet is also fixedly installed on the upper end of the fan casing. An impeller cover is movably installed on the rear side of the fan casing. A rotating shaft is fixedly installed in the middle of the rear side of the impeller cover. The rotating shaft is rotatably installed in the middle of the rear side of the fan casing. A pulley is also fixedly installed on the rotating shaft located on the rear side of the fan casing and is connected to the pulley at the output end of the motor via a belt. An impeller ring is provided on the front side of the impeller cover. Multiple blades are fixedly connected between the impeller cover and the impeller ring. A cleaning disc is movably connected between the multiple blades.

[0007] As a further preferred embodiment of this utility model, a through-hole is provided in the middle of the inner part of the rotating shaft and the middle of the impeller cover;

[0008] Based on this, a shaft hole is opened in the rotating shaft, which allows the telescopic rod to be inserted into it and to realize the horizontal pushing and pulling operation of the cleaning disc.

[0009] As a further preferred embodiment of the present invention, a bearing seat is fixedly installed in the middle of the front side of the cleaning disc, and the cleaning disc has multiple through slots, which are arranged in a ring around the middle of the cleaning disc in the front side of the cleaning disc, and the through slots are inserted into the outer side of the corresponding blades.

[0010] As a further preferred embodiment of this utility model, a rubber ring is fixedly installed on the front side of the cleaning disc near the through groove, and the inner side of the rubber ring is in contact with the outer surface of the corresponding blade.

[0011] Based on this, cleaning discs are interspersed between multiple blades, so that when the cleaning discs move horizontally, they can work with rubber rings to remove dust adhering to the blade surface.

[0012] As a further preferred embodiment of this utility model, a threaded groove is provided in the middle of one end of the telescopic rod, and a plurality of T-shaped mounting grooves are also provided near the threaded groove at one end of the telescopic rod. The T-shaped mounting grooves are arranged in a ring around the threaded groove at one end of the telescopic rod. A T-shaped top block is inserted and installed in the T-shaped mounting groove. A rubber layer is fixedly installed on the T-shaped top block. An adjusting bolt is threaded into the threaded groove. One end of the telescopic rod passes through the rotating shaft and is inserted and installed in the shaft seat through the shaft hole in the impeller cover. The end face of the T-shaped top block with the rubber layer is pressed into the shaft seat.

[0013] Based on this, by inserting one end of the telescopic rod into the electric telescopic device through multiple T-shaped top blocks, the telescopic rod will not rotate when the impeller cover rotates. This makes it easier to clean the blades by using the telescopic rod to drive the cleaning disc through multiple slots and rubber rings to clean multiple blades simultaneously.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-7 As shown, this utility model provides a copper converter air supply device, including a converter body 1, a base 2, and an air supply mechanism 3. Two sets of supporting mechanisms 4 are fixedly installed on the base 2. Two wheel rings 5 ​​are fixedly installed on the outer side of the converter body 1. The converter body 1 is movably mounted on the two sets of supporting mechanisms 4 through the two wheel rings 5. The air supply mechanism 3 includes a frame 26, a fan housing 6, and a motor 7. The fan housing 6 and the motor 7 are respectively fixedly installed on the frame 26. A pulley is fixedly installed at the output end of the motor 7, and the motor 7 is electrically connected to an external main controller through a connecting wire. A supporting tripod 8 is fixedly installed on the rear side of the frame 26. An electric telescopic device 9 is fixedly installed on the supporting tripod 8. The electric telescopic device 9 is electrically connected to an external main controller through a connecting wire. An internal telescopic rod 10 is movably installed, and multiple T-shaped top blocks 22 are movably installed at one end of the telescopic rod 10. An air inlet end 11 is opened on the front side of the fan casing 6, and a dust cover 27 is fixedly installed on the front side of the air inlet end 11. An air outlet end 12 is also fixedly installed on the upper end of the fan casing 6. An impeller cover 13 is movably installed on the rear side of the fan casing 6. A rotating shaft 25 is fixedly installed in the middle of the rear side of the impeller cover 13. The rotating shaft 25 is rotatably installed in the middle of the rear side of the fan casing 6, and a pulley is also fixedly installed on the rotating shaft 25 located on the rear side of the fan casing 6. The shaft is connected to the pulley at the output end of the motor 7 via a belt. An impeller ring 14 is provided on the front side of the impeller cover 13. Multiple blades 15 are fixedly connected between the impeller cover 13 and the impeller ring 14. A cleaning disc 16 is movably connected between the multiple blades 15.

[0026] like Figures 2-6As shown, a through-hole is provided in the middle of the rotating shaft 25 and the middle of the impeller cover 13. The shaft hole in the rotating shaft 25 allows the telescopic rod 10 to be inserted and realize the horizontal push-pull operation of the cleaning disc 16. A shaft seat 19 is fixedly installed in the middle of the front side of the cleaning disc 16. The cleaning disc 16 has multiple through slots 17, which are arranged in a ring around the middle of the cleaning disc 16. The through slots 17 are inserted and installed on the outer side of the corresponding blades 15. Since the cleaning disc 16 is located in the impeller cover 13, impeller ring 14, and blades... When the blade 15 rotates, it is close to the side of the impeller cover 13. Therefore, in order to balance the rotation of the blade 15, the weight of its impeller ring 14 is increased and is equivalent to the combined weight of the impeller cover 13, cleaning disc 16, and shaft seat 19. A rubber ring 18 is fixedly installed on the front side of the cleaning disc 16 near the through groove 17. The inner side of the rubber ring 18 is in contact with the outer surface of the corresponding blade 15. The cleaning disc 16 is interspersed between multiple blades 15, so that when the cleaning disc 16 moves horizontally, it can work with the rubber ring 18 to remove the dust attached to the surface of the blade 15.

[0027] like Figures 4-5 , Figure 7 As shown, a threaded groove 20 is provided in the middle of one end of the telescopic rod 10. Multiple T-shaped mounting grooves 21 are also provided near the threaded groove 20 at one end of the telescopic rod 10. The T-shaped mounting grooves 21 are arranged in a ring around the threaded groove 20 at one end of the telescopic rod 10. A T-shaped top block 22 is inserted into the T-shaped mounting groove 21, and a rubber layer 23 is fixedly installed on the T-shaped top block 22. An adjusting bolt 24 is threaded into the threaded groove 20, and one end of the telescopic rod 10 passes through the rotating shaft 25 and the shaft inside the impeller cover 13. The hole is inserted into the shaft seat 19. The end face of the T-shaped top block 22 with the rubber layer 23 is pressed into the shaft seat 19. One end of the telescopic rod 10 is inserted into the electric telescopic device 9 through multiple T-shaped top blocks 22. This ensures that the telescopic rod 10 will not rotate when the impeller cover 13 rotates. This makes it easier to clean the blades 15. The telescopic rod 10 can drive the cleaning disc 16 to clean multiple blades 15 simultaneously through multiple slots 17 and rubber rings 18.

[0028] It should be noted that this utility model is a copper converter air supply device. When it is necessary to clean the outer surface of the blade 15, the motor 7 can be stopped by the external main controller, so that the rotating shaft 25, impeller cover 13 and blade 15 stop rotating. Then, the electric telescopic device 9 is started, so that the telescopic rod 10 inside the electric telescopic device 9 gradually moves to the front of the fan housing 6. Then, the electric telescopic device 9 moves forward in the shaft hole of the rotating shaft 25 and the impeller cover 13 and, together with the three T-shaped top blocks 22, drives the shaft seat 19 to move forward. Then, the shaft seat 19 drives the cleaning disc 16 to move forward, and the multiple through grooves 17 inside the cleaning disc 16 move horizontally on the outer side of the corresponding blade 15 at the same time. This allows the rubber ring 18 near the through groove 17 on the front side of the cleaning disc 16 to scrape and clean the dust on the outer surface of the blade 15. When the telescopic rod 10 pushes the front side of the cleaning disc 16 to the rear side of the impeller ring 14, the telescopic rod 10 moves back to the return position, which can drive the cleaning disc 16 to reset, thereby completing the cleaning of the outer surface of the blade 15.

[0029] When it is necessary to separate the cleaning disc 16 from the telescopic rod 10, the end cover on the rear side of the fan housing 6 can be opened directly, and the impeller cover 13 can be taken out. Then, the adjusting bolt 24 can be unscrewed from the screw groove 20 using a tool. As a result, the outer side of the adjusting bolt 24 no longer presses against the three T-shaped top blocks 22, so that the T-shaped top blocks 22 can move in the direction of the screw groove 20 within the T-shaped mounting groove 21. This will prevent the end face of the T-shaped top block 22 with the rubber layer 23 from pressing against the inner side of the electric telescopic device 9, thereby allowing the shaft seat 19 to be pulled out from one end of the telescopic rod 10.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
