Description

Technical Field

[0001] This utility model relates to the technical field of metal waste recycling and processing equipment, and more specifically to a drum-type drying ball mill for tin-copper slag recycling and processing. Background Technology

[0002] Tin-copper slag refers to the waste generated during the smelting of tin or copper. These wastes often contain a certain amount of metal components. Therefore, recycling tin-copper slag not only helps reduce environmental pollution, but also effectively recovers and utilizes the useful resources within it.

[0003] In the treatment of tin-copper slag, as described in the publication (publication number: CN117418115A, A method for treating tin-copper slag) as "mixing and grinding tin-copper slag with alkali to obtain a grinding slurry", grinding equipment is required for the treatment.

[0004] Existing grinding equipment [such as Publication No.: CN206304829U, a drying ball mill] uses a heating device to heat the ground material for drying treatment;

[0005] The heating device used in the aforementioned drying ball mill is electromagnetic induction heating, which has fast heating efficiency and low energy consumption. However, electromagnetic induction heating itself needs to continuously generate heat during use, especially when supplying heat to the drum of the drying ball mill, which requires a large power. If only open heat dissipation is used, it will not provide sufficient protection for the electromagnetic induction heating component. Utility Model Content

[0006] The purpose of this utility model is to provide a drum-type drying ball mill for tin-copper slag recycling and treatment in order to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] This utility model proposes a drum-type drying ball mill for tin-copper slag recycling and treatment, including a drum, an arc-shaped heater disposed close to the outside of the drum, a frame fixed on the other side of the arc-shaped heater facing the drum, and multiple sets of heat dissipation holes respectively disposed on the frame. An arc-shaped cavity is formed between the inside of the frame and the arc-shaped heater, and the heat dissipation holes connect the arc-shaped cavity and the outside of the frame.

[0009] It also includes an air inlet mechanism that connects to the arc-shaped cavity and is fixed to the frame for blowing air from the center of the arc-shaped cavity to the center of the arc-shaped heater.

[0010] A heat-conducting plate, which is fixed inside the arc-shaped cavity, is used to direct the air blown toward the central end of the arc-shaped heater to the two arc-shaped sides of the arc-shaped cavity.

[0011] As a preferred embodiment of this utility model, the frame, air intake mechanism, and heat-conducting plate are made of non-magnetic and non-conductive materials.

[0012] As a preferred technical solution of this utility model, the air inlet mechanism includes an air inlet pipe and multiple sets of air distribution pipes. One end of each set of air distribution pipes is uniformly connected and fixed to one end of the air inlet pipe. The multiple sets of air distribution pipes are evenly distributed in a row and their other ends are fixed to the frame.

[0013] As a preferred technical solution of this utility model, the heat-conducting plate includes a V-shaped plate and through holes provided thereon. Multiple sets of through holes are provided and are respectively connected to the two ends of the V-shaped plate. The opening of the V-shaped plate is centered and faces the center end of the arc-shaped heater.

[0014] As a preferred embodiment of this utility model, the through holes on the V-shaped plate are symmetrically distributed on both sides opposite the center end of the V-shaped plate, and the through holes symmetrically distributed on both sides of the V-shaped plate gradually increase in size radially away from the center end of the V-shaped plate.

[0015] As a preferred embodiment of this utility model, the multiple sets of heat dissipation holes are evenly distributed on the frame.

[0016] The beneficial effects of this utility model are as follows:

[0017] The air intake mechanism blows air into the arc-shaped cavity and onto the arc-shaped heater, allowing heat to be expelled through the heat dissipation holes, thus improving heat dissipation capacity. At the same time, the heat-conducting plate can distribute the air to the two arc-shaped sides of the arc-shaped cavity, helping the air to be blown evenly to the entire arc-shaped heater, thereby improving the uniformity of heat dissipation and enhancing the protection of the arc-shaped heater.

[0021] like Figures 1-2 As shown, this utility model proposes a drum-type drying ball mill for tin-copper slag recycling and treatment, including a drum 1, an arc-shaped heater 2 disposed close to the outside of the drum 1, and an arc-shaped heater 2 disposed close to the bottom end of the drum 1.

[0022] The frame 3 is fixed on the other side of the arc heater 2 facing the roller 1, that is, the frame 3 is installed on the bottom side of the arc heater 2, so as not to block the processing surface of the top of the arc heater 2 facing the roller 1.

[0023] And multiple sets of heat dissipation holes 4 respectively provided on the frame 3, forming an arc cavity between the inside of the frame 3 and the arc heater 2, and the heat dissipation holes 4 connect the arc cavity with the outside of the frame 3 to provide heat dissipation for the arc cavity inside the frame 3;

[0024] Multiple sets of heat dissipation holes 4 are evenly distributed on the frame 3 to improve the uniformity of heat dissipation.

[0025] It also includes an air inlet mechanism 5, which is connected to the arc-shaped cavity and fixed to the frame 3, so as to blow air from the center end of the arc-shaped cavity to the center end of the arc-shaped heater 2. The air inlet mechanism 5 is fixed at the bottom end of the frame 3, and the air outlet end of the air inlet mechanism 5 is upward towards the center position of the bottom end of the arc-shaped heater 2. In this way, when the air blows to the bottom end of the arc-shaped heater 2, the air force can be evenly separated into front and back directions to improve the uniformity of air blowing.

[0026] The specific structure of the aforementioned air inlet mechanism 5 is as follows, and in conjunction with... Figures 1-2 As shown:

[0027] The air inlet mechanism 5 includes an air inlet pipe 51 and multiple sets of air distribution pipes 52. One end of each set of air distribution pipes 52 is uniformly connected and fixed to one end of the air inlet pipe 51. The multiple sets of air distribution pipes 52 are evenly distributed in a row and their other ends are fixed to the frame 3. The multiple sets of air distribution pipes 52 are evenly distributed from left to right at the bottom of the frame 3 and one end is connected to the arc-shaped cavity. The other ends of each set of air distribution pipes 52 are uniformly connected and fixed to the top end of the air inlet pipe 51. The other end of the air inlet pipe 51 is connected to air supply equipment such as a fan. The air is transmitted through the air inlet pipe 51 to the multiple sets of air distribution pipes 52 for even distribution and then evenly blown into the arc-shaped cavity.

[0028] By using an air inlet duct 51 to connect external air supply equipment such as fans, which are located away from the arc heater 2, the impact can be reduced or eliminated, and the protection is good.

[0029] The heat-conducting plate 6, which is fixed in the arc-shaped cavity, is used to distribute the air blown towards the central end of the arc-shaped heater 2 to the two arc-shaped sides of the arc-shaped cavity. This helps to distribute the air evenly to the entire arc-shaped heater 2, thereby improving the uniformity of heat dissipation (and a portion of the air can be blown to the central bottom end of the arc-shaped heater 2 through the heat-conducting plate 6 to further improve the uniform flow effect).

[0030] The specific structure of the heat-conducting plate 6 described above is as follows, and in conjunction with... Figures 1-2 As shown:

[0031] The heat-conducting plate 6 includes a V-shaped plate 61 and through holes 62 provided thereon. There are multiple sets of through holes 62, which are respectively connected to the two ends of the V-shaped plate 61. The opening of the V-shaped plate 61 is centered and faces the center end of the arc heater 2. The air from the air distribution pipe 52 is blown to the center of the bottom end of the V-shaped plate 61. The air is evenly guided back and forth through the V-shaped plate 61, and part of the air is blown directly to the bottom end of the arc heater 2 through the through holes 62 to improve the uniformity of air blowing.

[0032] The through holes 62 on the V-shaped plate 61 are symmetrically distributed on both sides opposite the central end of the V-shaped plate 61, and the through holes 62 symmetrically distributed on both sides of the V-shaped plate 61 gradually increase in size radially away from the central end of the V-shaped plate 61 (e.g., Figure 2 As shown, multiple sets of through holes 62 are symmetrically arranged on the left and right sides of the V-shaped plate 61. The diameter of these through holes 62 gradually increases from the center position away from the bottom of the V-shaped plate 61. This arrangement ensures that the airflow blowing directly onto the bottom of the V-shaped plate 61 and the airflow transmitted along the side can reach the bottom of the arc heater 2 with similar airflow, thereby further improving the uniformity of airflow to the arc heater 2.

[0033] Among them, the frame 3, the air inlet mechanism 5 and the heat conduction plate 6 are made of non-magnetic and non-conductive materials, so they will not heat up due to the electromagnetic field generated by the arc heater 2, thus avoiding safety hazards caused by overheating.

[0034] Meanwhile, the frame 3, air inlet mechanism 5, and heat conduction plate 6 are also made of high-temperature resistant materials, which can reduce heat damage caused by proximity to roller 1. [The frame 3, air inlet mechanism 5, and heat conduction plate 6 can be made of ceramic or high-temperature resistant plastic, etc.; high-temperature resistant plastic can be polyimide (PI) or polyphenylene sulfide (PPS), etc.]

[0035] It also includes a controller, which connects to an external power source to supply power to electrical components and control their opening and closing.

[0036] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
