Description

Technical Field

[0001] This utility model relates to the field of mixing machine technology, and in particular to a mixing machine for cold solidification pellet processing. Background Technology

[0002] In the metallurgical industry, the production of chilled pellets is a crucial step. With the development of the steel and other metal smelting industries, the requirements for the quality and quantity of chilled pellets are increasing. A mixing machine for chilled pellet processing plays a key role in the entire production process. The raw materials for chilled pellet processing typically include iron ore powder, binders, and other additives. These raw materials need to be thoroughly mixed to meet the requirements for pellet production. After mixing, due to differences in the mixing conditions of the raw materials and the complexity of the processing, shaped and unshaped raw materials will be produced. Therefore, effectively filtering the mixed materials and recycling the unshaped raw materials are key steps to improve production efficiency, reduce costs, and ensure product quality.

[0003] In existing cold-forming pellet processing mixing machines, there are generally basic structures such as a mixing tank and a motor driving a mixing blade for stirring. The mixing tank is mostly a barrel-shaped container made of metal, used to hold raw materials. The motor is connected to the mixing blade through a coupling. When the motor rotates, it drives the mixing blade to rotate, stirring and mixing the raw materials. Its filtration part usually adopts a simple filter screen structure. The material is initially separated by gravity through the filter screen. Some equipment uses a recycling method with a conveyor device set up outside the equipment. When it is necessary to recycle the unformed raw materials, the equipment must be stopped first, and the unformed raw materials must be manually taken out from the collection area and then poured into the mixing tank through the conveyor device. In terms of power transmission, belt drive or a single motor driving a single functional component is often used.

[0004] In existing cold-forming pellet processing mixing technology, there is a problem of inconvenient recycling of unformed raw materials. During the production process, when the mixed raw materials need to be recycled, due to equipment structure and technical limitations, it is often necessary to stop the machine first, then manually remove the collected unformed raw materials, and then pour them into the mixing tank through other auxiliary equipment or manually. This process not only consumes a lot of manpower and time costs, but also the frequent machine stoppages affect production efficiency and increase equipment wear. At the same time, manual operation may also introduce impurities and other uncertain factors, affecting the quality of the pellets. In addition, this method will also lead to a discontinuous production process, affecting the output and stability of the entire production line. Therefore, a mixing machine for cold-forming pellet processing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a mixing machine for cold solidified pellet processing, which aims to improve the problem in the prior art that the discharge contains unformed raw materials that cannot be directly recycled.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a mixing machine for cold-forming pellet processing, including a mixing tank 1. The mixing tank 1 is made of high-quality stainless steel, which has good corrosion resistance and strength and can withstand various forces during the mixing process and the erosion of raw materials. A connecting component is provided on the top of the mixing tank 1, which connects the devices. A top cover 3 is provided on the top of the mixing tank 1, and a fixed outer shell 4 is fixedly connected to the top of the top cover 3. The fixed outer shell 4 is made of sturdy cast iron and has a heat-insulating and anti-corrosion coating on its surface. A motor 2 14 is fixedly connected inside the fixed outer shell 4. A stirring blade 25 is fixedly connected to the output end of the motor 2 14. The stirring blade 25 is made of wear-resistant alloy steel and has a unique spiral pattern on its surface, which can improve the mixing efficiency and reduce the wear of the blades by the raw materials. A circulation component is provided at the bottom of the mixing tank 1, which circulates the raw materials. A filter component is provided at the bottom of the mixing tank 1, which filters the pellets.

[0033] The circulation assembly includes a collection box 8, which is made of carbon steel of moderate thickness. The inner wall of the box is coated with an anti-stick coating to facilitate the collection and flow of raw materials. A fixing rod 9 is fixedly connected to the top of the collection box 8, and a transmission pipe 7 is fixedly connected to one side of the fixing rod 9. The transmission pipe 7 is made of seamless steel pipe with good pressure resistance and wear resistance. A connecting shell 6 is fixedly connected to the top of the transmission pipe 7. A motor 13 is fixedly connected inside the connecting shell 6. A spiral blade 12 is fixedly connected to the output end of the motor 13. The spiral blade 12 is made of wear-resistant alloy steel, and the blade pitch is carefully designed to adapt to the transmission requirements of different raw materials. A guide pipe 5 is fixedly connected inside the transmission pipe 7, thereby circulating and processing the unformed filter material to prevent waste and enabling rapid circulation without stopping the device for refilling.

[0034] Specifically, in the raw material processing flow, the raw materials are poured into the mixing tank 1. Simultaneously, motor 214 starts, driving the mixing blades 25 to rotate at high speed. The mixing blades 25 thoroughly mix the raw materials within the mixing tank 1, ensuring uniform mixing of all components. After mixing, the raw materials undergo a filtration process. Unformed raw materials fall into the collection box 8. Subsequently, motor 13 starts working, driving the spiral blades 12 to rotate steadily. The spiral blades 12 slowly lift the raw materials inside the collection box 8, and then, through the guide pipe 5, the raw materials are circulated back into the mixing tank 1, initiating a new round of processing. This recycling significantly reduces production costs, for example, in some applications... In the cold-forming pellet processing of certain mineral raw materials with high demand, some unreacted or unsuitable raw materials are reused, which reduces the amount of new raw material procurement, saves money for enterprises, and reduces the extraction of natural resources. Taking iron ore as an example, the earth's iron ore resources are limited. Recycling can extend the life cycle of resources, alleviate the pressure of resource shortages, and make production continuous. Equipment does not need to be frequently shut down to wait for the preparation of new raw materials or to stop for maintenance due to raw material quality issues. The equipment can keep running continuously, give full play to its production capacity, thereby improving the utilization rate of equipment and reducing the depreciation cost per unit product.

[0035] Reference Figure 1 and Figure 2 The connecting assembly includes a connecting plate 2 and a fixing frame 10. The bottom of the connecting plate 2 is fixedly connected to the top of the mixing tank 1, the top of the connecting plate 2 is fixedly connected to the bottom of the top cover 3, the top of the fixing frame 10 is fixedly connected to the outer wall of the mixing tank 1, and the bottom of the fixing frame 10 is fixedly connected to the top of the collection box 8.

[0036] Specifically, the combined use of connecting plate 2 and fixing frame 10 provides multiple connection points and support surfaces for the device, making the connection between various components of the device tighter and effectively resisting various external forces generated during operation, such as vibration during stirring and impact of materials.

[0037] Reference Figure 1 and Figure 3The filter assembly includes a fixed plate 16, which is made of high-strength cast iron and precision-cast and machined to ensure a smooth surface and sufficient load-bearing capacity. A bidirectional motor 17 is fixedly connected to the top of the fixed plate 16, and an eccentric wheel 24 is fixedly connected to the output end of the bidirectional motor 17. The eccentric wheel 24 is forged from high-quality steel and heat-treated to give it high hardness and wear resistance. A transmission rod 19 is fixedly connected to the outer wall of the eccentric wheel 24. The transmission rod 19 is made of hollow stainless steel tube, which ensures strength while reducing weight. A connecting frame 18 is fixedly connected to the other end of the transmission rod 19. The connecting frame 18 is internally connected to... The filter has a filter layer 11. A fixing block 22 is fixedly connected to one side of the connecting frame 18. An elastic plate 23 is fixedly connected to the outer wall of the fixing block 22. The elastic plate 23 is made of high-performance rubber material and has good elasticity and fatigue resistance. Another fixing block 22 is fixedly connected to the bottom of the elastic plate 23. A partition 21 is fixedly connected to the outer wall of the other fixing block 22. The partition 21 is made of stainless steel plate with moderate thickness and good rigidity. The bottom of the partition 21 is fixedly connected to the top of the fixing plate 16. A guide plate 20 is fixedly connected to the outer wall of the partition 21. A drop hole 15 is opened at the bottom of the fixing plate 16 to facilitate the rapid filtration of the stirred material.

[0038] Specifically, the mixed material falls smoothly from the bottom of the mixing tank 1 to the top of the filter layer 11 under the principle of gravity. Then, the bidirectional motor 17 is started, driving the eccentric wheel 24 to rotate. Each rotation of the eccentric wheel 24 causes the transmission rod 19 to vibrate. Simultaneously, the elastic plate 23 connects the connecting frame 18 and the partition plate 21. Under the vibration transmission of the transmission rod 19 and the synergistic effect of the elastic plate 23, the filter layer 11 begins to vibrate efficiently. The formed raw material is precisely guided and collected in an orderly manner under the dual action of vibration and the guide plate 20, while the unformed material... The raw materials smoothly pass through the pores of the filter layer 11 into the interior of the baffle 21. Then, with the assistance of the internal slope, they precisely slide into the collection box 8 through the drop hole 15. This effectively removes impurities and non-compliant large particles from the stirred material. For example, in the processing of cold-formed pellets, it can remove unformed raw materials, making the pellet raw materials purer, thereby improving the quality of the cold-formed pellets and enhancing their performance in subsequent uses. For instance, the reduction reaction effect in metallurgical blast furnaces will be better, increasing the metal recovery rate. At the same time, compared with static filtration, vibration filtration speeds up the filtration process. Vibration causes the material to pass through the filter screen quickly, reducing the time occupied in the filtration stage, making the entire post-stirring processing flow more compact and efficient, and increasing the output per unit time.

[0039] Working principle: When processing raw materials, the raw materials are poured into the mixing tank 1, and the second motor 14 is started at the same time. The second motor 14 drives the mixing blades 25 to rotate, thereby stirring the raw materials. The stirred material falls from the bottom of the mixing tank 1 to the top of the filter layer 11. Then, the bidirectional motor 17 is started, which drives the eccentric wheel 24 to rotate. The eccentric wheel 24 then drives the transmission rod 19 to vibrate. In conjunction with the elastic plate 23, the connecting frame 18 and the partition plate 21 are connected to each other, thereby driving the filter layer 11 to vibrate. The formed raw materials are guided and collected by the guide plate 20, while the unformed raw materials enter the partition plate 21 through the filter layer 11 and then slide into the collection box 8 through the drop hole 15 via the internal slope. Then, the first motor 13 is started, which drives the spiral blades 12 to rotate. The spiral blades 12 then lift the raw materials in the collection box 8 and circulate them back into the mixing tank 1 through the guide pipe 5 for recycling processing, preventing raw material waste.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
