Description

Technical Field

[0001] This utility model relates to the field of scrap steel recycling technology, specifically to a special loading, unloading and transporting device for scrap steel recycling. Background Technology

[0002] Scrap steel recycling refers to the process of collecting, classifying, processing, and reusing scrap steel materials from industrial production and scrapped equipment. Its core is to achieve resource recycling and reduce steelmaking energy consumption. In the scrap steel recycling process, shearing equipment is used to cut the scrap steel into small pieces.

[0003] For example, a scrap steel feeding device for a blast furnace, with application number CN201921562810.0 and authorization announcement date of 20200623, includes a receiving mechanism, a weighing mechanism, and a conveyor belt. The receiving mechanism includes a receiving hopper and a feeder. The weighing mechanism is used to weigh the scrap steel transported by the receiving mechanism and includes a weighing hopper, a metering device, and an opener / closer. The conveyor belt includes a receiving belt and a feeding belt. The feeder continuously and evenly distributes the scrap steel onto the receiving belt and then conveys it to the weighing mechanism. The scrap steel flows out from the opening / closing point of the opener / closer, is conveyed through the feeding belt to the main charging belt of the blast furnace, and then transported into the blast furnace. The feeding device of this utility model is simple, easy to operate, highly automated, and efficient. The receiving hopper and weighing hopper in this utility model are self-made equipment, and other auxiliary tools can be reused. The conveyor belt is made of sintered or blast furnace feeding materials, resulting in low manufacturing costs.

[0004] When recycling scrap steel, it is added to a furnace for remelting. However, if the oil and moisture on the surface of the scrap steel are not effectively removed, direct smelting can easily lead to gas explosions in the furnace and an increase in slag impurities, affecting the safety and quality of scrap steel recycling. Therefore, it is urgent to design a special loading, unloading and transportation device for scrap steel recycling to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a special loading, unloading and transportation device for scrap steel recycling, so as to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A special loading, unloading and conveying device for scrap steel recycling includes a storage component. A heating component is provided on one outer wall of the storage component. The heating component includes a heating cylinder. A dustproof net is bolted to one end of the heating cylinder. A honeycomb heating net is bolted to the inside of the heating cylinder. A blower is bolted to the inside of the heating cylinder.

[0008] The storage component includes a tank with a cavity. The inner wall of the tank has multiple air holes that communicate with the cavity. One end of the heating cylinder is bolted to the outer wall of the tank and communicates with the cavity through a pipe.

[0009] Furthermore, the storage component is equipped with a discharge mixing component, which includes a drive module, and the output end of the drive module is bolted with an opening and closing plate.

[0010] Furthermore, the top of the output end of the drive module is equipped with a mounting shaft via a coupling, and multiple stirring rods are welded to the outer walls on both sides of the mounting shaft.

[0011] Furthermore, a scraper plate is bolted to the bottom of the mounting shaft, and the scraper plate is in contact with the bottom of the inner wall of the tank.

[0012] Furthermore, handles are welded to both outer walls of the tank, and a discharge port is opened on one side of the bottom of the inner wall of the tank, with the opening and closing plate sealing the discharge port.

[0013] Furthermore, the bottom of the tank is provided with an installation groove, which is connected to the unloading port.

[0014] Furthermore, an installation opening is provided at the center of the top of the inner wall of the mounting groove, and the bottom end of the mounting shaft is mounted inside the installation opening via a bearing.

[0015] Furthermore, the top of the drive module is bolted to the center of the top of the mounting groove, and a wireless communication module is provided on the drive module.

[0016] In the above technical solution, the special loading, unloading and conveying device for scrap steel recycling provided by this utility model has the following beneficial effects:

[0017] This invention utilizes the synergistic effect of the honeycomb heating mesh of the heating component and the blower to controllably heat the scrap steel inside the tank, causing surface oil stains to evaporate quickly and moisture to evaporate, significantly reducing the risk of gas explosions during smelting, improving the safety of scrap steel recycling, and also significantly reducing impurities in the slag.

[0018] The unloading mixing assembly designed in this utility model adopts a linkage design between the mixing rod and the scraper plate. The mounting shaft rotates under the drive module, and the scraper plate scrapes away the residual material at the bottom of the tank to ensure that the unloading port is not blocked.

[0019] The stirring rod designed in this invention will rotate under the drive of the drive module. The rotating stirring rod will stir the scrap steel inside the tank, causing the scrap steel inside the tank to turn over, which can improve the uniformity of heating when the heating component is heating, and will also further crush the scrap inside the tank.

[0020] The opening and closing plate, mounting groove, and mounting port designed in this utility model allow the opening and closing plate to rotate inside the mounting groove and unloading port when the drive module moves. The scrap steel inside the tank will flow out from the unloading port under the action of gravity and scraper plate. Due to the drive module, the scrap steel inside the tank will be discharged intermittently, achieving the purpose of intermittent scrap steel feeding and avoiding the problem of excessive scrap steel being fed at one time and hindering melting.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-5 As shown, the present invention provides a special loading and unloading transportation device for scrap steel recycling, including a storage component 1. A heating component 3 is provided on one side of the outer wall of the storage component 1. The heating component 3 includes a heating cylinder 16. A dustproof net 19 is installed at one end of the heating cylinder 16 by bolts. A honeycomb heating net 18 is installed inside the heating cylinder 16 by bolts. A blower 17 is installed inside the heating cylinder 16 by bolts.

[0031] The storage component 1 includes a tank 4, a cavity 6 is provided on the tank 4, and a plurality of air holes 7 are provided on the inner wall of the tank 4, and the air holes 7 are interconnected with the cavity 6. One end of the heating cylinder 16 is installed on the outer wall of one side of the tank 4 by bolts, and the heating cylinder 16 is interconnected with the cavity 6 by pipes.

[0032] Specifically, in this embodiment, a storage component 1 is included. A heating component 3 is provided on one outer wall of the storage component 1. The heating component 3 also uses a Siemens S7-1200 PLC and a temperature sensor. The PLC monitors the temperature of the heating cylinder 16 in real time through the temperature sensor and adjusts the heating power using a PID algorithm. The heating component 3 includes a heating cylinder 16. A dustproof net 19 is bolted to one end of the heating cylinder 16. A honeycomb heating net 18 is bolted inside the heating cylinder 16. The honeycomb heating net 18 is a ceramic substrate with a temperature resistance of 800℃, a power of 15kW, and a model of HT-Ceramic800. It is arranged in layers to achieve uniform heating. A blower 17 is bolted inside the heating cylinder 16. The blower 17 is preferably a CF-2000 model and is used to deliver hot air to the tank 4.

[0033] The storage component 1 includes a tank 4, a cavity 6 is provided on the tank 4, and multiple air holes 7 are provided on the inner wall of the tank 4. The blower 17 draws air into the heating cylinder 16, and the honeycomb heating mesh 18 heats it to a set temperature of 50-200℃. The hot air enters the cavity 6 of the tank 4 through the pipe, and is evenly sprayed out through the air holes 7, contacting the surface of the scrap steel to achieve oil volatilization and moisture evaporation. The air holes 7 and the cavity 6 are interconnected. One end of the heating cylinder 16 is installed on the outer wall of the side of the tank 4 by bolts, and the heating cylinder 16 is interconnected with the cavity 6 through the pipe.

[0034] This utility model provides a special loading and unloading transportation device for scrap steel recycling. Through the coordinated action of the honeycomb heating mesh 18 of the heating component 3 and the blower 17, the scrap steel in the tank 4 is heated at a controllable temperature, so that the surface oil stains evaporate quickly and the moisture evaporates, which significantly reduces the risk of gas explosion during smelting and improves the safety of scrap steel recycling. At the same time, it also significantly reduces the impurities in the slag.

[0035] In one embodiment provided by this utility model, such as Figure 2-4As shown, the storage component 1 is equipped with a discharge mixing component 2. The discharge mixing component 2 includes a drive module 11. The drive module 11 uses a servo motor, model Panasonic MINASA6, with a power of 3kW, and integrates a wireless communication module, model ESP32, which supports the Modbus RTU protocol and receives PLC commands. The output end of the drive module 11 is bolted to an opening and closing plate 14. The angle between the opening and closing plate 14 and the scraper plate 15 is 180 degrees. The top of the output end of the drive module 11 is connected to a mounting shaft 12 via a coupling. Multiple mixing rods 13 are welded to the outer walls on both sides of the mounting shaft 12. When the drive module 11 is started, it drives the mounting shaft 12 to rotate. The mixing rods 13 repeatedly scoop up and throw the scrap steel, increasing the heat contact area and improving the drying uniformity. The bottom of the mounting shaft 12 is bolted to a scraper plate 15, which is in contact with the bottom of the inner wall of the tank 4. Handles 5 are welded to both outer walls of tank 4. The handles 5 facilitate the installation of tank 4 with the hook of the crane. A discharge port 9 is opened on one side of the bottom of the inner wall of tank 4. When the mounting shaft 12 rotates, the scraper plate 15 and the opening and closing plate 14 are linked to ensure that no residue obstructs the flow of scrap steel when the discharge port 9 is opened. At the same time, when feeding, the drive module 11 receives instructions through the wireless communication module and starts and stops periodically to control the opening and closing of the opening and closing plate 14. When the opening and closing plate 14 rotates and opens, the scrap steel enters the inclined installation groove 8 through the discharge port 9 under the push of gravity and the scraper plate 15, realizing quantitative intermittent discharge. The opening and closing plate 14 is sealed inside the discharge port 9. The bottom end of tank 4 is provided with an installation groove 8, which is connected to the discharge port 9. An installation opening 10 is opened at the center of the top of the inner wall of the installation groove 8. The bottom end of the mounting shaft 12 is installed inside the installation opening 10 through a bearing. The top end of the drive module 11 is installed at the center of the top of the inner wall of the installation groove 8 through bolts. A wireless communication module is provided on the drive module 11.

[0036] Working principle: After the scrap steel enters the tank 4, the heating component 3 is activated. During this process, the blower 17 draws air into the heating cylinder 16, and the honeycomb heating mesh 18 is energized to heat the air, forming a high-temperature airflow. The hot air enters the cavity 6 of the tank 4 through the pipe and is evenly sprayed into the tank 4 through the air holes 7 on the inner wall, directly contacting the surface of the scrap steel to achieve oil evaporation and moisture evaporation. After heating for a period of time, the operation drive module 11 is activated, driving the mounting shaft 12 to rotate. The stirring rod 13 repeatedly scoops up and throws the scrap steel, increasing the heat contact area and improving the uniformity of drying. In addition, the end of the stirring rod 13 is equipped with a wear-resistant alloy layer to mechanically remove clumps of scrap steel. Mechanical crushing prevents large pieces of material from clogging the discharge port 9. During this process, the scraper plate 15 at the bottom of the mounting shaft 12 remains in contact with the bottom of the inner wall of the tank 4. As the mounting shaft 12 rotates, it scrapes off the attached residue to prevent material accumulation. When the mounting shaft 12 rotates, the scraper plate 15 is linked with the opening and closing plate 14 to ensure that no residue obstructs the flow of scrap steel when the discharge port 9 is open. At the same time, when feeding, the drive module 11 receives instructions through the wireless communication module and periodically starts and stops to control the opening and closing of the opening and closing plate 14. When the opening and closing plate 14 rotates open, the scrap steel enters the inclined mounting groove 8 through the discharge port 9 under the push of gravity and the scraper plate 15, realizing quantitative intermittent discharge.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
