Description

Technical Field

[0001] The utility model relates to the field of spraying tools, in particular to a refractory material spraying machine for a hot blast furnace. Background Art

[0002] A hot blast furnace is a device that provides hot air for industrial production. It is mainly composed of a combustion chamber, a heat exchanger, a fan and other parts. By burning fuel, high-temperature flue gas is generated, which exchanges heat with the air in the heat exchanger, thereby heating the cold air into hot air and sending it out through the fan. The inner wall of the hot blast furnace is sprayed with heat-resistant materials mainly to improve its heat resistance so that it can remain stable in a high temperature environment; enhance thermal insulation performance, reduce heat loss, and improve thermal efficiency; prevent chemical erosion, resist erosion by combustion products and harmful substances; and it is also easy to clean and maintain, so that the hot blast furnace can operate longer and more efficiently. Therefore, a refractory material sprayer for a hot blast furnace is needed, which can evenly spray the heat-resistant material on the inner wall of the hot blast furnace.

[0003] The working principle of existing refractory spraying machines for hot blast furnaces is generally as follows: using compressed air as the power source, first, the prepared refractory material is transported to the spray gun or spraying device, and under the push of compressed air, the refractory material is sprayed out from the nozzle of the spray gun at a certain speed and pressure. The sprayed refractory material will be evenly attached to the inner wall of the hot blast furnace to form a layer of refractory coating. In addition, some advanced spraying machines may have precise control systems, which can adjust the parameters such as the pressure, flow rate and output of the compressed air and refractory material according to different construction requirements, so as to meet the needs of various complex spraying operations.

[0004] However, in the actual use of the refractory spraying machine for hot blast furnaces, there are still some problems that need to be solved urgently. That is, after the spraying operation has been carried out for a long time, the refractory material is prone to agglomeration, or adheres to the barrel wall and is difficult to fall off. This results in a part of the refractory material being unable to be smoothly extracted during the spraying process, thereby causing waste of material. The emergence of this situation has greatly affected the practicality of the refractory spraying machine for hot blast furnaces, making it unable to fully exert its due effectiveness in actual applications, bringing inconvenience and trouble to the construction, which not only increases the construction cost, but also reduces the construction efficiency.

[0032] The stirring assembly includes a rotating column 5 and a stirring blade 6. The outer wall of the rotating column 5 is rotatably connected to the inner wall of the connecting plate 4. One end of the stirring blade 6 is fixedly connected to the outer wall of the rotating column 5. The driving assembly includes a driven gear 9, a motor 10 and a driving gear 11. One side of the driven gear 9 is fixedly connected to one end of the rotating column 5. The outer wall of the motor 10 is fixedly connected to one side of the frame 1 to provide power support for the rotation of the rotating column 5. The driving gear 11 is connected to the output end of the motor 10, and the driven gear 9 and the driving gear 11 are meshed. The extraction assembly includes an extraction tube 7 and an extraction head 8. The outer wall of the extraction tube 7 is rotatably connected to the inner wall of the rotating column 5. One end of the extraction head 8 is fixedly connected to one end of the extraction tube 7. The stirring blades 6 are arranged in a ring array and fixedly connected to the outer wall of the rotating column 5 to make the stirring more uniform. One side of the CNC platform 15 is fixedly connected to one end of the extractor 12.

[0033] Specifically, after starting the motor 10, its output end drives the driving gear 11 to rotate rapidly. Since the driving gear 11 and the driven gear 9 are meshed with each other, the rotation of the driving gear 11 will further drive the driven gear 9 to start rotating, and the driven gear 9 is fixedly connected to the rotating column 5, so the rotating column 5 will also rotate therewith.

There is a vertically connected plate on the fixing plate 16, which further enhances the structural strength of the fixing plate 16. The bottom surface of the air pump 17 is fixed on the fixing plate 16 to ensure the stable installation of the air pump 17. The side of the air pump 17 is fixed on the vertically connected plate, which makes the air pump 17 more firmly and reliably installed. The storage box 20 is fixed to one side of the frame 1 and the fixing plate 16. It not only provides storage space, but also can place the air guide tube 18 and the nozzle 19 inside it for storage, which is convenient for organizing and protecting these components to avoid them from being damaged or lost.

[0036] Working principle: When using the refractory spraying machine for hot blast furnaces, first put the refractory materials needed into the mixing barrel 2, then start the motor 10 to drive the driving gear 11 and then the driven gear 9, and then the driven gear 9 drives the rotating column 5 to rotate, and then the stirring blade 6 on the outer wall will be driven to start stirring at the same time. When the refractory materials are evenly stirred, the whole device is pushed to the vicinity of the equipment to be sprayed through the wheel 3, and then the nozzle 14 is taken out and aimed at the area to be sprayed, and then the extractor 12 is turned on. At this time, the refractory materials inside the mixing barrel 2 will be extracted from the extraction head 8 The paint is then drawn into the extraction pipe 7, and then enters the extraction machine 12 from the inside of the extraction pipe 7, and then is transported to the nozzle 14 through the delivery hose 13, and then sprayed out from the inside of the nozzle 14. The operator then holds the nozzle 14 to spray the area that needs to be sprayed. After the spraying is completed, the motor 10 and the extraction machine 12 in the equipment are stopped, and the air pump 17 is turned on. The operator then picks up the nozzle 19 to blow the dust generated by the spraying inside the spraying equipment to the vicinity of the air outlet of the hot air furnace, and then uses a plastic bag or other collection bag placed in advance to collect the blown dust to complete the entire spraying process.
