[0029] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] In order to solve the technical problem of low efficiency of treating the liquid remaining on the surface of the copper strip blank by using simple natural drying or centrifugal dehydration in the prior art, the present application provides a drying device.

[0031] Please refer to Figure 1 and Figure 2 The technical scheme of the present application provides a drying device, which comprises a device body 10, a first heating assembly 20 and a second heating assembly 30. The device body 10 is rotatably arranged. The device body 10 has a feeding port 11, a discharging port 12 and a containing cavity 13 for containing material 1. The feeding port 11 and the discharging port 12 are respectively communicated with the containing cavity 13. The first heating assembly 20 is connected with the device body 10 and a smelting furnace 2. The smelting furnace 2 has a waste heat recovery system 3. The first heating assembly 20 is used for receiving the hot gas collected by the waste heat recovery system 3 and supplying the hot gas into the device body 10, so as to heat and dry the material 1 in the containing cavity 13. The second heating assembly 30 is arranged outside the device body 10, and is used for heating the device body 10.

[0032] By the present application, the first heating assembly 20 directly uses the hot gas collected by the waste heat recovery system 3 of the smelting furnace 2 to dry and heat the copper strip blank in the device main body 10, without additional energy supply, greatly reducing the energy consumption in the drying process. And by combining the device main body 10 rotation dehydration and waste heat recovery heating, the emulsion and moisture on the surface of the copper strip blank are efficiently, energy-saving and thoroughly removed, avoiding the copper strip blank oxygen and hydrogen content exceeding the standard in the subsequent smelting process, thereby solving the technical problem of low efficiency of the prior art in treating the liquid remaining on the surface of the copper strip blank by using simple natural air drying or centrifugal dehydration, and improving the quality of the copper strip blank.

[0033] And the second heating assembly 30 as an auxiliary heat source can quickly supplement heat at the initial stage of drying the copper strip blank or when the hot gas temperature is insufficient, further improve the drying efficiency, and ensure that the drying effect is not affected, thereby improving the overall drying rate and effect.

[0034] In the present embodiment, the material 1 is a copper strip blank after milling; the device main body 10 is made of high-temperature-resistant stainless steel or alloy material.

[0035] In the present embodiment, the device main body 10 is cylindrically shaped and extends in the horizontal direction, and the inner wall of the device main body 10 is protrusively provided with a flow guide component to make the material 1 tumble in the containing cavity 13.

[0036] Through the setting of the flow guide component, the material 1 can be continuously tumbled and collided inside the device main body 10, and most of the emulsion and moisture can be thrown out by centrifugal force. And by the first heating assembly 20 using the hot gas collected by the waste heat recovery system 3 of the smelting furnace 2 to introduce into the device main body 10, the material 1 is heated to accelerate the evaporation of the emulsion and moisture, thereby improving the drying efficiency and ensuring the uniformity and thoroughness of the drying of the material 1.

[0037] In the present embodiment, the flow guide component includes at least one flow guide rib, and the at least one flow guide rib is arranged on the inner wall of the device main body 10; wherein when the flow guide rib is one, the flow guide rib is helical; when the flow guide rib is multiple, the multiple flow guide ribs are arranged parallel to each other, and each flow guide rib is arranged at an angle with the rotation axis of the device main body 10 or arranged parallel to each other.

[0038] When the flow guide rib is designed to be helical, as the device main body 10 rotates, the material 1 will advance along its path under the action of the flow guide rib, which promotes the material 1 to tumble spirally, increases the contact area and time of the material 1 with air, improves the heat exchange efficiency, and accelerates the drying process.

[0039] When multiple baffles are designed parallel to each other and at an angle or parallel to the axis of the device body 10, the multiple parallel baffles can guide the material 1 to form an orderly laminar flow in the containing cavity 13, avoiding the accumulation of the material 1 and ensuring the uniform distribution of hot air throughout the device body 10, avoiding local overheating or uneven drying, and improving the uniformity of the material 1 drying and product quality.

[0040] Regardless of whether the baffles are spiral or parallel, they can increase the flowability and tumbling frequency of the material 1 when the device body 10 is rotating, reducing the likelihood of the material 1 adhering to the inner wall of the device body 10, avoiding the phenomenon of blockage during the drying process of the material 1, and ensuring the continuity and efficiency of the drying process.

[0041] As shown in FIG. 1, Figure 2 In this embodiment, the device body 10 includes a first body 14 and a second body 15, the first body 14 is arranged around the second body 15, and an installation cavity 16 is formed between the first body 14 and the second body 15. The first heating assembly 20 includes a heating pipe 21, which is arranged in the installation cavity 16 and in contact with the first body 14 and the second body 15. One end of the heating pipe 21 is in communication with the waste heat recovery system 3 to collect hot air from the waste heat recovery system 3 for drying and heating the material 1 in the containing cavity 13.

[0042] Through the direct contact of the heating pipe 21 with the first body 14 and the second body 15, the material 1 in the containing cavity 13 can be efficiently and uniformly heated indirectly by the high-temperature flue gas or hot air collected by the waste heat recovery system 3 of the smelting furnace 2, thereby accelerating the drying process of the material 1. This double-layer heat conduction structure improves the utilization efficiency of heat and reduces the loss of heat during transmission, ensuring the rapidity and thoroughness of the drying process.

[0043] In addition, the direct communication of the heating pipe 21 with the waste heat recovery system 3 allows precise adjustment of the heating conditions in the device body 10 by controlling the flow and temperature of the hot air, ensuring that the material 1 is dried at an appropriate temperature, avoiding overheating or insufficient temperature, and improving product quality and controllability of production.

[0044] Using the waste heat generated by the smelting furnace 2 as a heat source not only avoids additional energy consumption such as electric heating or burning fossil fuels, but also greatly reduces production costs, meeting the modern industrial requirements of green production and energy saving and emission reduction. By recycling the waste heat resources in the production process, energy waste and environmental impact are effectively reduced.

[0045] In the embodiment, the first heating assembly 20 further comprises a ventilation pipeline 22, a heat exchanger and a temperature regulating valve, two ends of the ventilation pipeline 22 are connected with the heating pipeline 21 and the waste heat recovery system 3 respectively; the heat exchanger is arranged on the ventilation pipeline 22 and used for heating the hot gas provided by the waste heat recovery system 3 and feeding into the heating pipeline 21; the temperature regulating valve is arranged on the ventilation pipeline 22 and located between the heat exchanger and the waste heat recovery system 3, and used for controlling the opening and closing of the ventilation pipeline 22.

[0046] The hot gas from the waste heat recovery system 3 can be preheated in the ventilation pipeline 22 by the heat exchanger and then introduced into the device main body 10, the hot air flow rate is controlled at 1.5-2.5 m / s, and the ideal temperature required by the hot gas to dry is ensured. In this way, not only the waste heat generated by the smelting furnace 2 can be maximized, but also the low drying efficiency caused by insufficient temperature of the hot gas can be avoided, and the effective conversion and optimized utilization of energy are realized. The design of the temperature regulating valve enables the operator to accurately control the temperature and flow of the hot gas entering the heating pipeline 21 according to actual needs, avoids the adverse effects of excessively high or low temperature on the material 1, ensures the temperature consistency of the drying process, and improves the controllability and stability of the drying quality.

[0047] It can be seen that the structural configuration of the first heating assembly 20 not only greatly improves the energy utilization efficiency, ensures the temperature uniformity and controllability of the drying process, but also reduces the risk of equipment maintenance and production safety, embodies the versatility and flexibility of the drying device of the present application, and is suitable for efficient and energy-saving drying treatment of various materials 1.

[0048] In the embodiment, the heating pipeline 21 comprises at least one pipeline segment 210, and the at least one pipeline segment 210 is arranged in the mounting cavity 16; when the pipeline segment 210 is one, the pipeline segment 210 is in a spiral shape; when the pipeline segment 210 is multiple, the multiple pipeline segments 210 are arranged in parallel with each other and parallel to the axis of the device main body 10, and one end of the multiple pipeline segments 210 extending out of the mounting cavity 16 is connected with the waste heat recovery system 3.

[0049] When the pipeline segment 210 is arranged in a spiral shape, the contact area with the first main body 14 is increased, thereby improving the heat conduction efficiency of the hot gas to the device main body 10, so that the device main body 10 can be more uniformly heated, the evaporation of the internal moisture of the material 1 is accelerated, and the drying rate is improved.

[0050] When the plurality of pipe sections 210 are arranged parallel to each other and parallel to the axis of the device body 10, each pipe section 210 can independently and uniformly transmit heat energy to the device body 10, and this design can further improve the uniformity of heat energy distribution, especially for a device body 10 with a large length-diameter ratio, which can ensure uniform heat energy distribution in the entire length direction and improve the consistency of the drying effect. Moreover, the design of the plurality of parallel pipe sections 210 can flexibly adjust the heating intensity by adjusting the hot gas flow of each pipe section 210 according to actual drying requirements, which is suitable for processing materials 1 with different water contents or different drying requirements, and improves the adaptability and flexibility of the device.

[0051] Whether it is a single spiral pipe section 210 or a combination of a plurality of parallel pipe sections 210, it can greatly improve the heat conduction efficiency, drying uniformity, and application flexibility of the drying device, while reducing energy consumption and production costs, ensuring efficient, energy-saving, and environmentally friendly production processes.

[0052] In this embodiment, the second heating assembly 30 includes a plurality of heating elements 31, which are arranged at intervals around the device body 10, and each heating element 31 is in contact with the outer wall of the device body 10. The heating element 31 is an infrared heating pipe.

[0053] The infrared heating pipe can quickly generate heat and directly act on the outer wall of the device body 10, thereby rapidly increasing the temperature in the containing cavity 13 and accelerating the drying process. Especially in the case of requiring rapid response or the initial water content of the material 1 being high, infrared heating can quickly provide additional heat energy and shorten the drying time.

[0054] The plurality of infrared heating pipes as auxiliary heat sources are arranged around the device body 10 for low-temperature stage heat supplement, which can ensure uniform heating of the outer wall of the device body 10, thereby making the temperature distribution in the containing cavity 13 more uniform and further improving the drying efficiency. This avoids local overheating or insufficient heating and improves the quality and consistency of the dried material 1.

[0055] Using an infrared heating pipe as the second heating assembly 30 not only further improves the drying efficiency and the uniformity of heating, but also enhances the flexibility and controllability of the drying process, and has multiple advantages such as energy saving, environmental protection, easy maintenance, and improved automation level. Especially for the metal processing field, it can effectively improve the drying quality and production efficiency of materials 1 such as copper strip blank milling materials.

[0056] In the embodiment, the drying device further comprises a feeding assembly 40 located at the feeding port 11, the feeding assembly 40 comprising a negative pressure fan 41, a suction pipe 42 and a feeding control valve, two ends of the suction pipe 42 being connected with the surface milling machine 4 and the feeding port 11 respectively, the negative pressure fan 41 being arranged on the suction pipe 42 for sucking the material 1 milled by the surface milling machine 4 into the suction pipe 42, and the feeding control valve being arranged on the suction pipe 42 and located between the surface milling machine 4 and the negative pressure fan 41 for controlling the opening and closing of the suction pipe 42.

[0057] Through the cooperation of the negative pressure fan 41 and the suction pipe 42, the material 1 milled by the surface milling machine 4 can be automatically sucked into the containing cavity 13 without manual intervention, which not only improves the feeding efficiency, but also reduces the labor cost and operation error, and realizes the continuity and automation of the drying process. Compared with the positive pressure conveying or other mechanical conveying methods, the use of the negative pressure fan 41 has lower energy consumption and can ensure the stable transmission of the material 1, avoiding additional energy consumption caused by blockage of the material 1 and reducing the overall operation cost of the drying device.

[0058] The arrangement of the feeding control valve enables the operator to control the opening and closing of the suction pipe 42 as needed, thereby accurately adjusting the feeding speed and amount of the material 1 and ensuring the stability and controllability of the drying process.

[0059] It can be seen that the design of the feeding assembly 40 not only realizes the automation and accurate control of the material 1 entering the drying device, but also improves the efficiency and safety of the material 1 transmission, reduces the energy consumption and maintenance cost, and has a significant promoting effect on improving the performance and production efficiency of the entire drying device.

[0060] In the embodiment, the drying device further comprises a driving assembly 50 arranged on one side of the device main body 10, the driving assembly 50 comprising a driving component 51 and a speed reducer 52, the speed reducer 52 being connected with the output end of the driving component 51, a first matching part being arranged on the output end of the speed reducer 52, a second matching part being arranged on the outer peripheral wall of one end of the device main body 10, and the first matching part and the second matching part being connected with each other in cooperation to drive the device main body 10 to rotate by the driving component 51. The driving component 51 is a driving motor, and the first matching part and the second matching part are transmission wheels or other components, which can achieve the transmission of the output torque of the speed reducer 52 to the device main body 10.

[0061] Through the arrangement of the speed reducer 52, the high-speed output of the driving component 51 can be converted into the low-speed high-torque rotation required by the device main body 10, ensuring the accurate control of the rotation speed of the device main body 10. This is crucial for the drying process, because different materials 1 and drying stages may require different rotation speeds to achieve the best drying effect and efficiency.

[0062] And the speed reducer 52 enables the driving component 51 to output greater torque at lower power, so that the device body 10 can maintain stable rotation speed even in a high load state, improving the carrying capacity and durability of the equipment, especially when processing heavy or large batches of materials 1. It can be seen that through the design of the driving assembly 50 and its cooperation with the device body 10, not only the accurate rotation speed control and high torque output during the drying process of the material 1 are ensured, but also the stability and safety of the equipment are improved.

[0063] In the embodiment, the drying device further comprises a conveying assembly located at the discharge port 12, one end of the conveying assembly being connected with the packing machine 5, and at least part of the conveying assembly being movably arranged for conveying the dried material 1 in the device body 10 into the packing machine 5 for packing.

[0064] Through the automatic design of the conveying assembly, the need for manual handling of the material 1 is avoided, the labor cost is reduced, and the risk of material 1 loss caused by manual operation is also avoided, improving the production efficiency and consistency of material 1 processing. Moreover, the material 1 is directly conveyed from the drying device to the packing machine 5 without the need for intermediate stay or repositioning, which shortens the total time of material 1 processing and speeds up the production process, especially when processing large batches of material 1. This continuous flow of material 1 can significantly improve the production capacity.

[0065] It can be seen that the design of the conveying assembly greatly improves the automation degree of material 1 processing, reduces the time and energy loss in the material 1 transmission process, and ensures the integrity and production safety of the material 1, which is an important part of realizing automated and efficient production in the metal processing field. The dried copper strip blank enters the packing machine 5 for packing, and is packed into different sizes of blocks, and then enters the smelting furnace 2 for copper strip blank production.

[0066] In the embodiment, the drying device further comprises an integrated PLC controller for controlling the motor speed, negative pressure intensity, heating temperature, feeding and discharging time and other parameters to realize full-automatic operation.

[0067] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects:

[0068] By the present application, the first heating assembly 20 directly uses the hot gas collected by the waste heat recovery system 3 of the smelting furnace 2 to dry and heat the copper strip blank in the device main body 10, without additional energy supply, greatly reducing the energy consumption in the drying process. And by combining the device main body 10 rotation dehydration and waste heat recovery heating, the emulsion and moisture on the surface of the copper strip blank are efficiently, energy-saving and thoroughly removed, avoiding the copper strip blank oxygen and hydrogen content exceeding the standard in the subsequent smelting process, thereby solving the technical problem of low efficiency of the prior art in treating the liquid remaining on the surface of the copper strip blank by using simple natural air drying or centrifugal dehydration, and improving the quality of the copper strip blank. The second heating assembly 30 as an auxiliary heat source can quickly supplement heat when the copper strip blank is initially dried or the hot gas temperature is insufficient, further improving the drying efficiency and ensuring that the drying effect is not affected, thereby improving the overall drying rate and effect.
