Description

Technical Field

[0001] The utility model relates to the field of metal smelting, in particular to a feeding device of a smelting furnace. Background Art

[0002] With the development and demand of the times, the separation, refining and purification industry of precious metals has gradually formed and developed, and with the improvement of people's environmental awareness, various precious metal industries have increased their investment in the field of scrap metal recycling. In the smelting process of precious metals, when the precious metal content is low, multiple metal alloys need to be separated, or non-metallic impurities need to be removed, smelting is usually an effective method. Smelting refers to the process of heating metals or other substances above their melting point to convert them into liquid for separation, refining or alloying. In order to achieve smelting, a smelting furnace that can heat the raw materials to the required temperature is usually required. The smelting furnace usually has a feeding device to transmit metal raw materials to it. The raw materials are usually ore, waste and slag, which are in various forms. The traditional feeding device has a simple structure, is easy to install and maintain, and can be manually adjusted and adapted to various forms of metal raw materials. However, the traditional feeding device is manually operated, which makes its production efficiency low and cannot accurately control the amount and speed of material delivery. In the smelting process of precious metals, the feeding equipment needs to be able to feed continuously, stably and evenly. If the feeding is intermittent or unstable, the smelting process will be interrupted, affecting the production efficiency. If the smelting furnace is not fed evenly, it may cause temperature and pressure fluctuations inside the smelting furnace, which will increase the risk of damage to the smelting furnace.

[0003] Nowadays, common feeding devices include bucket feeders, belt feeders and vibrating feeders. Compared with traditional feeding devices, these new feeding devices are all automated equipment and do not require manual intervention, thereby improving production efficiency and production quality. However, these new feeding devices all have some problems, such as: they cannot effectively convey granular, powdered and other raw materials, and uneven material distribution may occur during the feeding process. These new feeding devices have complex structures and transmission systems, and most of the structures are integrated structures, so the disassembly and assembly of components is very troublesome, and the maintenance cost of components is higher than that of traditional feeding devices. Today's feeding devices can work continuously for a long time and use them intensively, which leads to the need to replace their parts regularly. The use of traditional feeding devices will result in low production efficiency, while the use of new feeding devices will result in inconvenient maintenance and insufficient scope of application of raw material forms, which creates a dilemma.

[0004] Therefore, it is necessary to provide a feeding device for a metal smelting furnace which is easy to maintain and can evenly transport raw materials in various forms. Utility Model Content

[0043] Please refer to Figure 1 - Figure 8 An embodiment of the utility model provides a feeding device 500 for a smelting furnace, which is used to transport materials into the smelting furnace. The feeding device 500 includes: a base 3, a material trough 4, a chain conveying mechanism 1 and a screw conveying mechanism 2.

[0044] The base 3 is arranged on the ground. The trough 4 is fixed on the base 3. The chain conveyor mechanism 1 is arranged on the ground and is provided with a driving device. The chain conveyor mechanism 1 conveys materials into the trough 4. The screw conveyor mechanism 2 is located between the base 3 and the trough 4. The screw conveyor mechanism 2 is connected to the base 3 and the trough 4. The screw conveyor mechanism 2 includes a feed shell 21 fixedly connected to the base 3 and the trough 4, and also includes a discharge shell 22 connected to the feed shell 21, and a screw shaft 23 located in the feed shell 21 and the discharge shell 22. The feed shell 21 receives the material entering the trough 4. The screw shaft 23 is provided with a spiral blade, and the screw shaft 23 is connected to the output shaft of the motor 24. The screw shaft 23 rotates, and the spiral blade pushes the material to one end of the screw shaft 23, and this end is located in the discharge shell 22. The feed shell 21 is provided with an integrally formed flange, and the discharge shell 22 is also provided with an integrally formed flange, and the flange of the feed shell 21 and the flange of the discharge shell 22 are fixed by bolts to connect the feed shell 21 and the discharge shell 22.

[0045] Among them, the base 3 is set on the ground and the trough 4 is fixed thereon, which ensures the stability and reliability of the entire feeding device 500 during the working process. This stable support structure helps to reduce vibration and movement, and ensure the accuracy and stability of material transportation. The chain plate conveying mechanism 1 is responsible for conveying materials from the outside to the trough 4. It is provided with a driving device, which can efficiently convey materials to the trough 4, ensuring the continuity and efficiency of the production process. The screw conveying mechanism 2 conveys materials from the feed port to the trough 4 through the rotation of the screw shaft 23 and the screw blade. This design can effectively push the material into the smelting furnace, ensuring the uniform delivery and melting of the material. The design of the feed shell 21 and the discharge shell 22 being formed in one piece, coupled with bolt fixing, ensures a stable connection between the two components, avoiding failures or leakage caused by loose connection. The bearing seat 25 is located on the surface of the feed shell 21, which is provided with a circular hole, and the stable operation of the screw shaft 23 is ensured by fixing the screw shaft 23. This design can effectively reduce bearing wear and friction and extend the service life of the equipment.

[0046] Among them, the feed shell 21 is located above the trough 4 to receive the material entering the trough 4, and the spiral blades on the spiral shaft 23 push the material to one end of the spiral shaft 23 by rotating, and the end is located in the discharge shell 22. This design ensures that the material can be smoothly transported from the feed port to the discharge port 221, ensuring the continuity and efficiency of the smelting process. The integrally formed flanges on the feed shell 21 and the discharge shell 22 and the bolt fixation ensure a firm connection between the two components. This design can prevent leakage or loosening problems caused by loose connections, ensuring the safety and reliability of the material conveying process. The integrally formed flange and bolt fixation simplify the connection structure between the feed shell 21 and the discharge shell 22, making it easier for maintenance personnel to repair and operate. At the same time, it also reduces potential failure points and improves the stability and reliability of the equipment.

[0047] More preferably, the chain conveyor mechanism 1 includes: a sprocket 11 , a chain 12 and a conveyor plate 13 .

[0048] The sprocket wheel 11 is connected to the driving device of the chain conveying mechanism 1. The chain 12 is placed on the sprocket wheel 11 and meshed with the sprocket wheel 11. The conveying plate 13 is fixed to the chain 12 to convey materials.

[0049] Among them, the sprocket 11 is connected to the driving device, the chain 12 is placed on the sprocket 11 and meshed with it, and the chain 12 is driven to move by the rotation of the sprocket 11. This transmission method has the advantages of high transmission efficiency and ability to withstand large loads, and is suitable for the working environment of the conveying mechanism. The chain 12 is fixed on the sprocket 11 and meshed with it to form a stable transmission system. This design makes it difficult for the conveying mechanism to have problems such as chain jumping and loosening during operation, ensuring the stability and reliability of the conveying. A conveying plate 13 is fixed on the chain 12, and the conveying plate 13 can be adjusted and replaced as needed to adapt to the conveying of materials of different types, sizes and weights, thereby improving the flexibility and adaptability of the equipment. The structure of the chain 12 conveying mechanism is relatively simple, and it is relatively easy to maintain and replace wearing parts such as the chain 12 and the sprocket 11. This design reduces maintenance costs and repair time, and improves the maintainability of the equipment.

[0050] More preferably, in the chain conveyor mechanism 1, the direction in which the conveyor plate 13 is lifted is recorded as the first direction F1, and the direction in which the conveyor plate 13 is lowered is recorded as the second direction F2. The sprocket 11 rotates and pulls the chain 12, and the chain 12 drags the conveyor plate 13 to rise along the first direction F1, and the conveyor plate 13 reaches the high point of the chain conveyor mechanism 1, and the high point is located above the trough 4. The conveyor plate 13 dumps the material into the trough 4 at the high point, and after passing the high point, the conveyor plate 13 descends along the second direction F2.

[0051] Among them, the chain conveyor mechanism 1 rises along the first direction F1, the conveying plate 13 reaches the high point, and the material is smoothly dumped into the trough 4. The gravity is used to accelerate the material conveying process, thereby improving the conveying efficiency. The material is poured into the trough 4 by gravity, and no additional energy input is required, which saves energy costs during the conveying process. The method of conveying materials by natural gravity simplifies the structural design of the conveying system, reduces complex mechanical devices, and reduces maintenance costs and failure rates. By placing the conveying plate 13 at the high point of the chain conveyor mechanism 1, the uniform distribution of the material when pouring into the trough 4 is ensured, and the accumulation and blockage of the material is avoided. The material descends in the natural direction, which reduces the possibility of external force intervention and reduces the safety risks during operation.

[0052] Preferably, the chain conveyor mechanism 1 further comprises: a support frame 14. The support frame 14 is fixedly connected to the ground and is located above the ground to support the chain conveyor mechanism 1.

[0053] Among them, the main function of the support frame 14 is to provide a stable support structure to ensure that the chain conveyor mechanism 1 does not shake or tilt during operation. The position above the ground can better support the conveying mechanism, reduce the swing of the mechanism, and maintain its stability. By fixing the support frame 14 directly to the ground, the vibration and noise generated by the conveying mechanism during operation can be effectively reduced. This helps to improve the comfort of the working environment and reduce the operating noise of the machine. A stable support structure can reduce the risk of tipping or collapse of the conveying mechanism, thereby improving the safety of operators and equipment. This is especially important for industrial equipment that runs for a long time because they require stable support to prevent accidents. By fixing the support frame 14 directly to the ground, the weight of the conveying mechanism can be prevented from causing damage or indentation to the ground. This helps to extend the service life of the ground and reduce the cost of ground maintenance.

[0054] More preferably, the discharge shell 22 is provided with a discharge port 221 , and the discharge port 221 is located on the surface of the discharge shell 22 , and the surface is located on a side close to the ground.

[0055] Among them, the discharge port 221 is set on the surface of the discharge shell 22, which can conveniently control the outflow of materials from the conveying mechanism, so that the materials can flow out smoothly and unimpeded, thereby improving production efficiency. The setting of the discharge port 221 on the side close to the ground helps to smoothly export the materials to the ground, facilitates the subsequent material collection, transportation or processing, and makes the material processing more convenient and efficient. The discharge port 221 is located on the side close to the ground, which can reduce the height of the material falling from the discharge port 221 to the ground, reduce the impact of the material falling to the ground, and help reduce the breakage and damage of the material. The discharge port 221 is set on the side of the surface of the discharge shell 22 close to the ground, so that the operator can more conveniently observe and control the outflow of materials, which is conducive to the safety and accuracy of the operation. The discharge port 221 is set on one side of the discharge shell 22 close to the ground, which can reduce the space required for the conveying equipment, make the equipment more compact, and suitable for workplaces with limited space.

[0056] More preferably, the direction in which the screw shaft 23 rotates is recorded as a third direction F3; the screw shaft 23 rotates around the third direction F3, and the spiral blades of the screw shaft 23 rotate and propel toward the discharge port 221 of the discharge shell 22.

[0057] Among them, the spiral shaft 23 rotates around the third direction F3, so that the spiral blade is pushed toward the discharge port 221, and the material can be effectively pushed to the discharge port 221. This design can improve the material conveying efficiency of the feeding device 500 and ensure that the material flows out of the trough 4 smoothly. The design of the spiral blade rotating and pushing toward the discharge port 221 helps to prevent the accumulation and backlog of materials in the trough 4, ensure the continuous flow of materials in the trough 4, reduce the blockage and accumulation of the trough 4, and improve the stability and reliability of the equipment. The spiral blade is pushed toward the discharge port 221 to ensure that the material is pushed out of the trough 4 as much as possible, reduce the amount of material remaining in the trough 4, reduce the difficulty of cleaning and maintenance, and improve the cleanliness and sanitary conditions of the equipment. According to specific production process requirements, setting the rotation direction of the spiral shaft 23 to rotate and push the material toward the discharge port 221 may be more in line with the needs of the process flow, which is conducive to improving production efficiency and product quality.

[0058] Preferably, the screw conveying mechanism 2 further includes: a bearing seat 25. The bearing seat 25 is arranged on the surface of the feed shell 21, has a circular hole on the surface, and is located on the side of the feed shell 21 away from the discharge shell 22. The bearing seat 25 is provided with a circular hole, and the screw shaft 23 passes through the circular hole on the surface of the feed shell 21, and the screw shaft 23 passes through the circular hole of the bearing seat 25, and one end of the screw shaft 23 passing through the circular hole is fixedly connected to the bearing seat 25; the diameter of the circular hole of the feed shell 21 is the same as the diameter of the screw shaft 23, and the diameter of the circular hole of the bearing seat 25 is the same as the diameter of the screw shaft 23.

[0059] Among them, the bearing seat 25 provides support and fixing functions for the screw shaft 23, ensuring the stability and reliability of the screw shaft 23 during operation. By passing the screw shaft 23 through the circular hole of the bearing seat 25, the position of the screw shaft 23 can be fixed to prevent it from shaking or offsetting during operation, thereby ensuring the normal operation of the feeding device 500. Installing the bearing seat 25 on the surface of the feed shell 21 can reduce the friction and resistance between the screw shaft 23 and the feed shell 21 when rotating, and improve the operation efficiency and energy saving of the feeding device 500. The design of the bearing seat 25 is simple and easy to install, which can reduce the installation cost and maintenance difficulty of the equipment. At the same time, by making the circular hole diameter of the feed shell 21 the same as the diameter of the screw shaft 23, and the circular hole diameter of the bearing seat 25 the same as the diameter of the screw shaft 23, the matching between the bearing seat 25 and the screw shaft 23 can be ensured, simplifying the manufacturing and installation process. As one of the key components of the feeding device 500, the stability of the screw shaft 23 directly affects the conveying effect of the material. By fixing the bearing seat 25, it can be ensured that the screw shaft 23 will not shake or deviate when rotating at a high speed, thereby ensuring stable transportation of materials.

[0060] More preferably, the motor 24 of the screw conveying mechanism 2 is located on a side of the bearing seat 25 away from the feed shell 21, and the motor 24 is connected to the screw shaft 23, and the motor 24 drives the screw shaft 23 to rotate around the third direction F3.

[0061] Among them, installing the motor 24 on one side of the bearing seat 25 helps to save space for the feeding device 500. In industrial equipment, space utilization is usually important, so combining the motor 24 with the bearing seat 25 can make more efficient use of the space of the equipment. Connecting the motor 24 directly to the screw shaft 23 can reduce the use of transmission elements such as the transmission chain 12 or belt. Such a design simplifies the transmission system, reduces energy loss, and improves energy utilization. Since the motor 24 is located on one side of the bearing seat 25, maintenance personnel can more easily access the motor 24 for maintenance and maintenance. This design makes the inspection and maintenance of the motor 24 simpler and more convenient. Placing the motor 24 on one side of the bearing seat 25 can better protect the motor 24 from the external environment, such as preventing dust, water vapor and other impurities from corroding the motor 24, thereby extending the service life of the motor 24. The motor 24 is located on one side of the bearing seat 25, which is easy to connect to the control system, so as to facilitate the control and adjustment of the operation of the feeding device 500 to meet different process requirements and production needs.

[0062] Thus, by connecting the feed shell 21 and the discharge shell 22 with flanges, the shells can be disassembled for easy maintenance, and the spiral blades are used to push the materials, thereby improving the flexibility of the spiral conveying mechanism 2 in transporting materials of various forms.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
