Description

Technical Field

[0001] This utility model belongs to the field of metal smelting technology, specifically a crusher for smelting copper slag in lead smelting. Background Technology

[0002] Copper dross originates from the pyrometallurgical refining process of crude lead. Lead ore generally contains copper. During pyrometallurgical lead smelting, copper enters the crude lead. The pyrometallurgical refining of crude lead typically employs a copper removal process involving melting and precipitation. As the temperature of the molten lead decreases, impurities such as copper, sulfur, arsenic, and antimony precipitate out, forming solid dross that floats on the surface of the molten lead—this is copper dross. Copper dross typically contains elements such as Pb, Cu, S, As, Sb, and Ag, and has some recycling value.

[0003] In the existing technology, when recovering copper dross, a crusher is required to break it down first. However, the existing crusher can only break large pieces of copper dross into smaller pieces. After that, other equipment is still needed to separate the dust and metal from the smaller pieces of copper dross, which results in low work efficiency. In order to solve the above problems, a crusher for copper dross smelting in lead smelting is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the above problems by providing a pulverizer for smelting copper slag in lead smelting, comprising:

[0005] The support leg has a separation mechanism fixedly installed on its top. Two connecting rods are welded to one side of the separation mechanism. A crushing mechanism is welded to the top of the two connecting rods. A crushing chamber is fixedly installed on the upper surface of the crushing mechanism. A crushing roller rotates inside the crushing chamber.

[0006] The second motor is fixedly installed at the bottom of the separation mechanism. A rotating seat is fixedly installed at the end of the output shaft of the second motor. Rotating rods are hinged to both the left and right sides of the rotating seat, and a pressure roller is rotatably connected to one side of each rotating rod.

[0007] The above technical solution involves first placing copper smelting slag into the crushing chamber, where the crushing rollers rotate to initially crush the slag. At this point, small particles of copper smelting slag enter the separation mechanism. A second motor drives a rotating seat to rotate, which in turn drives a rotating rod to follow its trajectory. This causes the pressure roller to crush the small particles of copper smelting slag, thus separating the dust and metal within the slag. This process can complete the crushing and separation of copper smelting slag in one operation, greatly improving work efficiency.

[0008] In a preferred embodiment, a first motor is fixedly installed on one side of the upper surface of the crushing mechanism, a transmission disc is fixedly installed on one side of the crushing roller, and a transmission belt is provided between the output shaft of the first motor and the transmission disc.

[0009] Through the above technical solution, the first motor drives the transmission disc to rotate, and the transmission disc drives the crushing roller to rotate.

[0010] In a preferred embodiment, two connecting plates are welded to both the left and right sides of the crushing mechanism, and spring rods are provided at the bottom of each of the four connecting plates. Inclined guide plates are provided at the bottom of each of the four spring rods, and a vibration motor is fixedly installed on one side of each inclined guide plate.

[0011] With the above technical solution, after the copper smelting slag is crushed, it enters the upper surface of the inclined guide plate. The vibration motor drives the spring rod to make the inclined guide plate vibrate continuously, thus realizing automatic feeding.

[0012] In a preferred embodiment, a scraper is fixedly mounted on one side of the bottom of the rotating seat.

[0013] Through the above technical solution, the scraper is driven to rotate along its trajectory during the operation of the rotating seat, thereby turning up the copper smelting slag at the bottom of the separation mechanism.

[0014] In a preferred embodiment, a top rod is fixedly installed on one side of the upper end of the rotating seat, and a scraper is fixedly installed at the end of the top rod, the scraper being in contact with the inner wall of the separation mechanism.

[0015] Through the above technical solution, the scraper is driven to rotate along its trajectory during the operation of the rotating seat, thereby scraping off the copper smelting slag adhering to the inner wall of the separation mechanism.

[0016] In a preferred embodiment, a handle is rotatably connected to the outer wall of the support leg, and a sealing plate is fixedly installed at the bottom of the handle, the sealing plate being located on the upper surface of the bottom inside the separation mechanism.

[0017] In a preferred embodiment, the bottom of the separation mechanism is provided with a through groove that is adapted to the sealing plate.

[0018] In summary, due to the adoption of the above technical solutions, the beneficial effects of this utility model are: this utility model proposes a pulverizer for smelting copper slag in lead smelting.

[0019] First, copper smelting slag is placed inside the crushing chamber. The crushing roller rotates to initially crush the copper smelting slag inside the crushing chamber. At this time, the small copper smelting slag particles enter the separation mechanism. The second motor drives the rotating seat to rotate, and the rotating seat drives the rotating rod to move along its trajectory, so that the pressure roller crushes the small copper smelting slag particles, thereby crushing and separating the small copper smelting slag particles and separating the dust and metal in the copper smelting slag. The crushing and separation of copper smelting slag can be completed in one go, which greatly improves the work efficiency. Attached Figure Description

[0026] The following will combine Figure 1-4 A detailed description is provided of a pulverizer for smelting copper slag in lead smelting according to an embodiment of the present invention.

[0027] Example:

[0028] A pulverizer for smelting copper slag in lead smelting includes:

[0029] The support leg 1 has a separation mechanism 2 fixedly installed on its top. Two connecting rods 3 are welded to one side of the separation mechanism 2. A crushing mechanism 4 is welded to the top of the two connecting rods 3. A crushing chamber 5 is fixedly installed on the upper surface of the crushing mechanism 4. A crushing roller 6 rotates inside the crushing chamber 5. A first motor 7 is fixedly installed on one side of the upper surface of the crushing mechanism 4. A transmission disc 8 is fixedly installed on one side of the crushing roller 6. A transmission belt is set between the output shaft of the first motor 7 and the transmission disc 8. The first motor 7 drives the transmission disc to rotate, and the transmission disc 8 drives the crushing roller 6 to rotate. First, the copper smelting slag is put into the crushing chamber 5. The copper smelting slag in the crushing chamber 5 is initially crushed by the rotation of the crushing roller 6. At this time, the small particles of copper smelting slag enter the separation mechanism 2.

[0030] The crushing mechanism 4 has two connecting plates 9 welded on both the left and right sides. Each of the four connecting plates 9 has a spring rod 10 at its bottom. Each of the four spring rods 10 has an inclined guide plate 11 at its bottom. A vibration motor 12 is fixedly installed on one side of the inclined guide plate 11. When the copper smelting slag is crushed, it enters the upper surface of the inclined guide plate 11. The vibration motor 12 drives the spring rods 10 to make the inclined guide plate 11 vibrate continuously to achieve automatic feeding.

[0031] The second motor 13 is fixedly mounted at the bottom of the separation mechanism 2. A rotating seat 14 is fixedly mounted at the end of the output shaft of the second motor 13. Rotating rods 15 are hinged to both sides of the rotating seat 14. A pressure roller 16 is rotatably connected to one side of the rotating rod 15. A scraper 17 is fixedly mounted on one side of the bottom of the rotating seat 14. During the operation of the rotating seat 14, the scraper 17 rotates along its trajectory, thereby turning up the copper smelting slag at the bottom of the separation mechanism 2. A top rod 18 is fixedly mounted on one side of the upper end of the rotating seat 14. A scraper 19 is fixedly mounted at the end of the top rod 18. The scraper 19 and... The inner wall of the separation mechanism 2 is in contact with the rotating seat 14. During the operation of the rotating seat 14, the scraper 19 is driven to rotate along its trajectory, thereby scraping off the copper smelting slag adhering to the inner wall of the separation mechanism 2. The second motor 13 drives the rotating seat 14 to rotate, and the rotating seat 14 drives the rotating rod 15 to move along its trajectory, thereby crushing the small copper smelting slag particles with the pressure roller 16, thereby crushing and separating the small copper smelting slag particles, separating the dust and metal in the copper smelting slag, and completing the crushing and separation of copper smelting slag in one go, which greatly improves the work efficiency.

[0032] A handle 20 is rotatably connected to the outer wall of the support leg 1. A sealing plate 21 is fixedly installed at the bottom of the handle 20. The sealing plate 21 is located on the upper surface of the bottom of the separation mechanism 2. A through groove adapted to the sealing plate 21 is opened at the bottom of the separation mechanism 2. After the copper smelting slag is separated, the sealing plate 21 is rotated by rotating the handle 20. At this time, the sealing plate 21 moves out from the upper surface of the through groove, so that the material is discharged through the through groove.

[0033] Working principle:

[0034] First, copper smelting slag is placed inside the crushing chamber 5. The crushing roller 6 rotates to initially crush the copper smelting slag inside the crushing chamber 5. At this time, small copper smelting slag particles enter the separation mechanism 2. The second motor 13 drives the rotating seat 14 to rotate. The rotating seat 14 drives the rotating rod 15 to move along its trajectory, thereby causing the pressure roller 16 to crush the small copper smelting slag particles, thus crushing and separating the small copper smelting slag particles. The dust and metal in the copper smelting slag are separated. The crushing and separation of copper smelting slag can be completed in one go, which greatly improves the work efficiency.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
