Technical Field
[0001] This utility model relates to the technical field of recycled aluminum recycling devices, specifically a pretreatment device for recycled aluminum recycling. Background Technology
[0002] Recycled aluminum is an aluminum alloy or aluminum metal obtained by remelting and refining scrap aluminum and aluminum alloy materials or aluminum-containing waste. It is an important source of metallic aluminum.
[0003] In the production of recycled aluminum, pretreatment of the waste material is necessary. Crushing and screening are particularly important steps in this process. Existing crushing and screening equipment breaks down waste aluminum into smaller pieces for easier subsequent processing. While existing crushing and screening equipment is integrated and can perform screening during crushing and feeding, the filters on the screening equipment tend to clog after prolonged use. Cleaning requires workers to tighten multiple bolts, which is cumbersome, increases maintenance time, and hinders work efficiency.
[0004] Therefore, we propose a pretreatment device for recycled aluminum. Utility Model Content
[0005] One of the technical problems this application aims to solve is that the filter screen on the screening equipment is prone to clogging. When cleaning, the operator needs to tighten multiple bolts, which is troublesome, increases the maintenance time of the screening equipment, and makes it difficult to improve work efficiency.
[0006] To address the aforementioned technical problems, this application provides a pretreatment device for recycled aluminum, comprising a crushing box and a support frame. The crushing box is mounted on the support frame, with a feed hopper at the top. Inside the crushing box, a pair of mating crushing rollers are arranged. Outside the crushing box, a primary motor for driving the crushing rollers and a gear set connected to the crushing rollers are provided. The device also includes a screening mechanism comprising a sealing cover and a filter cover. The sealing cover is connected to the support frame, and the sealing cover and the filter cover are interconnected to form a cylindrical shape. A connecting hopper communicating with the sealing cover is located at the bottom of the crushing box. The screening mechanism is used to screen the crushed material.
[0007] In some embodiments, the screening mechanism further includes a pusher auger disposed on the sealing cover, and a second motor for driving the pusher auger is mounted on the sealing cover.
[0008] In some embodiments, the filter cover has uniformly distributed coarse material holes and fine material holes, the fine material holes being located below the connecting hopper, and the auger pushing the broken material from the fine material holes toward the coarse material holes.
[0009] In some embodiments, a discharge port is provided at the end of the sealing cover and the filter cover away from the second motor, and a discharge ramp is provided at this end of the filter cover.
[0010] In some embodiments, mounting slide rails are provided on both sides of the sealing cover, and mounting guide rods that cooperate with the mounting slide rails are provided on both sides of the filter cover. Corresponding screw holes are opened at one end of the mounting slide rails and the mounting guide rods, and fixing bolts are installed in the screw holes.
[0011] In some embodiments, a notch is provided at the first end of the mounting slide rail, the notch is connected to the mounting slide rail, and the mounting guide rod can slide into the mounting slide rail from the notch.
[0012] In some embodiments, symmetrically distributed guide plates are provided on the inner wall of the feed hopper.
[0013] This utility model has at least the following beneficial effects:
[0014] 1. By setting up a sealing cover, filter cover, mounting slide rail and mounting guide rod, the slide rail installation structure only requires a single fixing bolt to limit and fix the filter cover, eliminating the need for multiple bolts, reducing the number of bolts that workers need to disassemble, saving disassembly and assembly time, thus facilitating quick maintenance and cleaning of the filter cover, making installation more convenient and time-saving, thereby effectively improving work efficiency and high practicality;
[0015] 2. By setting a notch at the beginning of the installation slide rail, the notch is larger than the installation slide rail, thus eliminating the need to align the installation guide rod with the installation slide rail, thereby achieving a quick installation function. This reduces the time that workers spend picking up the filter cover during installation, reduces manpower consumption, facilitates operation, and improves practicality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1:
[0024] Please see Figures 1 to 4 The technical solution provided by this utility model is as follows: A pretreatment device for recycled aluminum includes a crushing box 1 and a support frame 6. The crushing box 1 is mounted on the support frame 6. A feed hopper 2 is provided on the top of the crushing box 1. A pair of cooperating crushing rollers 3 are provided inside the crushing box 1. A primary motor 4 for driving the crushing rollers 3 and a gear set 5 connected to the crushing rollers 3 are provided outside the crushing box 1. The device also includes a screening mechanism 8, which includes a sealing cover 9 and a filter cover 11. The sealing cover 9 is connected to the support frame 6. The sealing cover 9 and the filter cover 11 are connected to each other to form a cylindrical shape. A connecting hopper 7 communicating with the sealing cover 9 is provided at the bottom of the crushing box 1. The screening mechanism 8 is used to screen the crushed material.
[0025] In this embodiment, as Figures 1 to 3 As shown, when the device is powered on and started, the waste material to be crushed and screened is put into the feed hopper 2. The crushing roller 3 crushes the waste material and then it falls from the connecting hopper 7 into the space covered by the sealing cover 9 and the filter cover 11.
[0026] In this embodiment, as Figures 1 to 3As shown, the screening mechanism 8 also includes a pusher auger 15 mounted on the sealing cover 9. A second motor 16 for driving the pusher auger 15 is mounted on the sealing cover 9. The filter cover 11 has evenly distributed coarse material holes 13 and fine material holes 14. The fine material holes 14 are located below the connecting hopper 7. The pusher auger 15 pushes the crushed material from the fine material holes 14 toward the coarse material holes 13. A discharge port 10 is provided at the end of the sealing cover 9 and the filter cover 11 away from the second motor 16. A discharge inclined plate 12 is provided at this end of the filter cover 11. The coarse material holes 13 and the fine material holes 14 can further screen crushed material of different sizes. With the pusher auger 15 and the discharge port 10, the screening device has three screening levels, which optimizes the screening function.
[0027] In this embodiment, as Figure 3 and Figure 4 As shown, both sides of the sealing cover 9 are provided with mounting slide rails 17, and both sides of the filter cover 11 are provided with mounting guide rods 18 that respectively cooperate with the mounting slide rails 17. One end of the mounting slide rails 17 and the mounting guide rods 18 are provided with corresponding screw holes 21, and fixing bolts 20 are installed in the screw holes 21. With the slide rail installation structure, only a single fixing bolt 20 is needed to limit and fix the filter cover 11, eliminating the need to use multiple bolts, reducing the number of bolts that workers need to disassemble, saving disassembly and assembly time, thus facilitating quick maintenance and cleaning of the filter cover 11, making installation more convenient and time-saving, thereby effectively improving work efficiency and high practicality.
[0028] In this embodiment, as Figure 3 and Figure 4 As shown, a notch 19 is provided at the first end of the mounting slide rail 17. The notch 19 is connected to the mounting slide rail 17. The mounting guide rod 18 can slide into the mounting slide rail 17 from the notch 19. During installation, the mounting guide rod 18 is first placed in the notch 19. Pushing the filter cover 11 will slide the mounting guide rod 18 from the notch 19 into the mounting slide rail 17. Since the notch 19 is larger than the mounting slide rail 17, this setting can eliminate the need to align the mounting guide rod 18 with the mounting slide rail 17, thereby achieving the function of quick installation, reducing the time for workers to pick up the filter cover 11 during installation, reducing manpower consumption, facilitating operation and improving practicality.
[0029] In this embodiment, as Figure 3 and Figure 4 As shown, during disassembly, simply loosen the fixing bolt 20 counterclockwise to move the filter cover 11 horizontally and remove it. After cleaning the blockage of the coarse material hole 13 and fine material hole 14, during installation, place the installation guide rod 18 in the notch groove 19, push the filter cover 11 to slide the installation guide rod 18 from the notch groove 19 into the installation slide rail 17, and tighten the fixing bolt 20. The operation is simple and convenient.
[0030] The implementation principle of a pretreatment device for recycled aluminum in this application embodiment is as follows: During disassembly, simply unscrew the fixing bolts 20 counterclockwise to move the filter cover 11 horizontally and clean the blockage of the coarse material holes 13 and fine material holes 14. During installation, place the installation guide rod 18 in the notch groove 19, push the filter cover 11 to slide the installation guide rod 18 from the notch groove 19 into the installation slide rail 17, and tighten the fixing bolts 20 to complete the fixing. This setting eliminates the need to align the installation guide rod 18 with the installation slide rail 17, thereby achieving the function of quick installation, reducing the time for workers to pick up the filter cover 11 during installation, reducing manpower consumption, facilitating operation and improving practicality.
[0031] With the sliding rail installation structure, the filter cover 11 can be fixed with only a single fixing bolt 20, eliminating the need for multiple bolts, reducing the number of bolts that workers need to disassemble, saving disassembly and assembly time, thus facilitating quick maintenance and cleaning of the filter cover 11, making installation more convenient and time-saving, thereby effectively improving work efficiency and high practicality.
[0032] Example 2:
[0033] Please see Figure 5 The technical solution provided by this utility model is as follows:
[0034] Unlike Embodiment 1, symmetrically distributed guide plates 22 are provided on the inner wall of the feed hopper 2. The two guide plates 22 are symmetrically inclined, and the reserved opening between them is located in the crushing gap of the two crushing rollers 3, so that the aluminum material can fall accurately into the crushing opening, which has the function of guiding the material and also reduces the flying of fragments out of the crushing box 1 during crushing, thus having a limiting function.
