[0002] Waste electrical appliances contain a variety of metal resources such as copper and iron, which have very high recycling value. At present, in the process of recycling waste metals, they are centrally crushed and then separated by cyclone separation equipment to separate different types of metals to complete the recycling process. The recycled metal powder can be further used after refining.

[0003] In the above process, when the crushed metal chips fall into the cyclone separation equipment from the front-end equipment, the air inlet speed of the cyclone separation equipment is generally constant. When the crushed metal chips enter the cyclone separation equipment, the metal chips may slightly adhere to each other due to the adhesion of oil stains. Therefore, their falling speed cannot be kept constant, that is, the feeding speed of the cyclone separation equipment cannot be kept constant. When the feeding speed is too fast, too much metal chips will cause a certain obstruction to the radial direction of the airflow inside the equipment, thereby affecting the cyclone separation effect.

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0028] Reference Figure 1-4 The first embodiment of the utility model provides a scrap metal recycling device, including a cyclone separation device 1 and a crushing part 13 for crushing the entire electrical appliance, and also includes the following parts:

[0029] A feed port 2 fixedly arranged relative to the cyclone separation device 1 and a first opening and closing component 3 arranged at the feed port 2, the feed port 2 is butted against the unloading position of the crushing part 13, and its minimum passing diameter is adjusted by the first opening and closing component 3;

[0030] The bearing part 4 is movably arranged relative to the cyclone separation device 1, and the movable mode is that there is an elastic relationship between the bearing part 4 and the cyclone separation device 1. In addition, the positional relationship between the multiple components therein is that the crushed metal chips will pass through the feed port 2 and the top of the bearing part 4 in sequence when they fall after leaving the crushing part 13, and finally reach the feed end of the cyclone separation device 1, so as to perform cyclone separation processing. When the metal chips fall on the bearing part 4, the movable relationship of the bearing part 4 will form a downward pressure on the bearing part 4;

[0031] There is a linkage relationship between the bearing part 4 and the first opening and closing component 3. When the bearing part 4 moves vertically, the first opening and closing component 3 will move synchronously, thereby adjusting the minimum passing diameter of the feed port 2.

[0032] Based on the above components and their relative positional relationship, when the device is working, after the waste electrical appliances are crushed at the crushing part 13, the metal chips enter the feed port 2, fall onto the bearing part 4, and finally fall into the feed end of the cyclone separation device 1; in this process, if the speed at which the metal chips enter the feed port 2 is too fast, due to the large amount of metal chips, a certain degree of downward pressure will be exerted on the bearing part 4, causing it to undergo vertical elastic yield movement. Through linkage, the first opening and closing component 3 will reduce the maximum passing diameter of the feed port 2, thereby reducing the feeding speed. The adjustment range is determined according to the vertical downward movement degree of the bearing part 4, that is, the faster the feeding speed is, the greater the adjustment range of the first opening and closing component 3. The larger the section amplitude is, the lower the feeding speed will be, and the degree of gravity pressure on the supporting part 4 by the metal chips will be, so that it can be reset upward to a certain extent through the elastic relationship, so that the first opening and closing component 3 can be adjusted in the opposite direction, so as to restore the minimum passing diameter of the feed port 2 accordingly; therefore, compared with the prior art, the device can effectively control the speed at which the crushed metal chips enter the cyclone separation equipment 1 during the recovery process of the electrode metal chips, so as to prevent the rapid feeding from affecting the separation process of the metal chips, thereby fully improving the cyclone separation effect, so as to improve the separation effect between various metal chips, so as to better carry out the subsequent metal refining process.

[0033] Further, see Figure 1-4 A guide channel 5 is fixedly connected between the feed port 2 and the feed end of the cyclone separation device 1, and the bearing part 4 is movably arranged inside the guide channel 5, so as to provide a certain external protection effect for the bearing part 4 to prevent it from being disturbed by external touch during operation; in addition, the guide channel 5 can also shield the falling metal chips to prevent external impurities from falling into it, or prevent metal chip powder from being scattered around and causing pollution.

[0034] Further, see Figure 2-4 The bearing part 4 and the guide channel 5 form a vertical sliding fit, and the sliding method is that the bracket can be fixedly connected to the bearing part 4, and the bracket and the wall shell of the guide channel 5 are slidably inserted, thereby ensuring the sliding stability of the bearing part 4 on the guide channel 5; the relative activity relationship of the bearing part 4 relative to the cyclone separation device 1 is ensured by setting the vertical sliding relationship, and only the vertical activity form is retained, thereby filtering out the movement in other directions, so that the bearing part 4 can complete the vertical movement more accurately according to the pressure of the metal chips, thereby fully completing the corresponding activity amplitude according to the weight of the metal chips.

[0035] Further, see Figure 2-4The bearing part 4 is in the shape of a plate, and its plate surface is inclined. The plate-shaped structure can increase the horizontal bearing area of ​​the metal chips, thereby improving the carrying capacity, making the pressure on the metal chips greater, so that the amplitude of its own movement can be amplified, so that the action information fed back to the first opening and closing component 3 during the linkage process is more accurate; and through the inclined setting of the bearing part 4, the metal chips fall into the upper part thereof and then slide briefly and finally fall into the cyclone separation device 1, thereby ensuring that the metal chips have a certain residence time after falling thereon, and will not continue to accumulate, thereby further ensuring that the weight of the metal chips can be reflected more accurately.

[0036] Further, see Figure 2-4 , regarding the linkage mode between the bearing part 4 and the first opening and closing component 3, the device also includes a first chamber 6 and a second chamber 7 that are interconnected, and there is a relatively fixed relationship between the two. The first chamber 6 is connected to the exhaust end of the cyclone separation device 1 and maintains a relatively fixed relationship. The first chamber 6 is provided with an air outlet 8, and a second opening and closing component 9 that is linked to the bearing part 4 is provided between the first chamber 6 and the second chamber 7, and the first opening and closing component 3 performs corresponding actions according to the pressure inside the second chamber 7. For the formation of the first chamber 6 and the second chamber 7, a shell can be used here and fixedly connected to the cyclone separation device 1;

[0037] Based on this, when the cyclone separation device 1 is exhausting, the gas is discharged into the first chamber 6 and finally discharged through the outlet 8. In this process, due to the connection relationship, the gas will also fill the second chamber 7. Since the gas carries kinetic energy when the cyclone separation device 1 is exhausting, the second chamber 7 will also be subject to exhaust pressure, that is, air pressure is generated inside. If the minimum diameter of the connection between the first chamber 6 and the second chamber 7 is larger, more gas enters the second chamber 7, and the internal pressure of the second chamber 7 is greater. Through the linkage cooperation between the second opening and closing component 9 and the bearing part 4, the greater the downward movement amplitude of the bearing part 4, the greater the increase amplitude of the minimum connection diameter between the two chambers controlled by the second opening and closing component 9 The larger the value, the pressure in the second chamber 7 is roughly proportional to the downward movement amplitude of the bearing part 4. Through this relationship, when the pressure in the second chamber 7 changes, it drives the first opening and closing component 3 to perform corresponding actions, that is, when the pressure increases, the feed inlet 2 is adjusted to make its own minimum passing diameter correspondingly smaller, and vice versa, thereby achieving a linkage effect between the bearing part 4 and the first opening and closing component 3; this setting indirectly achieves the linkage effect between the bearing part 4 and the first opening and closing component 3 by relying on the exhaust pressure of the cyclone separation equipment 1. Due to the constant air intake factor, the stability of the exhaust pressure can be fully maintained, so that the movement amplitude of the first opening and closing component 3 during the reaction will be more accurate.

[0038] Further, see Figure 2-4 Regarding the implementation method of the first opening and closing component 3 moving with the pressure of the second chamber 7, the first opening and closing component 3 may include a baffle 301 slidably arranged at the feed port 2, and a driving cylinder 302 relatively fixedly arranged at the feed port 2, the driving cylinder 302 is pneumatically connected to the second chamber 7, and can be connected through a pipeline, which is omitted in the figure, the output end of the driving cylinder 302 is connected to the baffle 301, and the sliding of the baffle 301 can correspondingly block the cross-sectional surface of the feed port 2 to adjust its minimum passing diameter, the baffle 301 A first spring assembly 10 is connected to the feed port 2, and its elastic force keeps the baffle 301 from sliding to keep the feed port 2 in a state of maximum passing diameter when not subject to other external forces; specifically, when the pressure in the second chamber 7 increases, the pressure in the driving cylinder 302 increases accordingly through the connecting effect, thereby pushing the baffle 301 to overcome the elastic force it is subjected to and slide to a corresponding extent according to the pressure, so as to adjust the minimum passing diameter of the feed port 2; this design makes the structure simple and easy to implement, while fully ensuring the sensitivity of the first opening and closing assembly 3 to move with pressure.

[0039] Further, see Figure 2-4 Regarding the second opening and closing component 9, it includes a sealing plate 901 movably arranged in the first chamber 6. The first chamber 6 and the second chamber 7 are connected through a through opening 14. A second spring component 11 is connected between the sealing plate 901 and the inside of the first chamber 6. The sealing plate 901 is pressed against the surface of the through opening 14 by its elastic force. A connecting rod 12 is fixedly connected between the sealing plate 901 and the bearing part 4. The connecting rod 12 directly slides through the shell of the second chamber 7. The sealing plate 901 is connected to the bearing part 4 by the connecting rod 12. The bearing parts 4 form a whole so that synchronous movements can be performed. The elastic force of the second spring assembly 11 ensures that the bearing part 4 has an elastic relationship with the cyclone separation device 1. When the bearing part 4 is pressed and moved downward, the sealing plate 901 moves downward synchronously to open the through hole 14. The greater the downward movement, the greater the degree to which the through hole 14 is opened, and the easier it is for the gas to enter the second chamber 7, so that the pressure in the second chamber 7 is greater. The cooperation of the sealing plate 901 makes the pressure regulation of the second chamber 7 simple and accurate.

[0040] Further, see Figure 2-4 The sealing plate 901 and the first chamber 6 are arranged to slide relative to each other, thereby fully ensuring the stability of the movement process of the sealing plate 901. Regarding the sliding mode of the sealing plate 901, one end of the connecting rod 12 can extend to the bottom of the sealing plate 901 and slide with the exhaust end of the cyclone separation device 1.

[0041] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
