[0047] In this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0048] Given that the current production process for crushing and grinding copper ore is carried out by separate crushers and grinders, this process not only increases the transfer of copper ore and occupies a large area, but also results in insufficient grinding of copper ore due to the inability to perform repeated grinding.
[0049] Combination Figures 1-3 As shown, this embodiment of the present invention provides a crushing and grinding device for copper wire preparation, comprising: a body 1 having a cavity, which is divided from top to bottom into a through crushing chamber 11, a grinding chamber 12, and a collecting chamber 13. A feed hopper 5 is provided at the top of the body 1, and the feed hopper 5 is configured as the first channel for copper ore to enter the interior of the body 1.
[0050] The crushing chamber 11 is equipped with a crushing component 2 located directly below the feed hopper 5. The crushing component 2 is configured to perform preliminary crushing of the copper ore.
[0051] A grinding component 3 is located directly below the crushing component 2 inside the grinding chamber 12. The grinding component 3 is configured to perform a further grinding operation on the copper ore that has been initially crushed by the crushing component 2, thereby obtaining finer copper ore. Outside the grinding chamber 12, that is, on the outside of the machine body 1, a transmission component 4 is provided. The copper ore that has been ground by the grinding component 3 but has not met the standard is transferred to the grinding component 3 for further grinding through the transmission component 4. This process is repeated until all the copper ore that has been initially crushed by the crushing component 2 is ground to the standard state.
[0052] Collection chamber 13 is configured as the main location for centralized collection of copper ore that has passed the grinding test.
[0053] Specifically, such as Figures 1-3 As shown, the crushing component 2 includes several parts such as a first motor 21 and a crushing roller 22.
[0054] The first motor 21 is symmetrically arranged on the outer wall of the crushing chamber 11. Each first motor 21 has a crushing roller 22 installed on its output shaft. The two crushing rollers 22 are also symmetrically arranged. Each crushing roller 22 is rotatably located inside the crushing chamber 11, and multiple crushing teeth 23 are arranged on the outer circumference of each crushing roller 22.
[0055] The grinding assembly 3 includes several parts such as a second motor 31, a driving wheel 32, a driven wheel 33, a first grinding roller 34, and a second grinding roller 35.
[0056] The second motor 31 is mounted on the outer wall of the grinding chamber 12. The driving wheel 32 is rotatably mounted on the outer wall of the grinding chamber 12, opposite to the second motor 31. The driven wheel 33 is meshed with the driving wheel 32. The first grinding roller 34 is rotatably mounted inside the grinding chamber 12, with one end connected to the drive end of the second motor 31 and the other end connected to the driving wheel 32. The second grinding roller 35 is rotatably mounted parallel to the first grinding roller 34 inside the grinding chamber 12, with one end fixedly connected to the driven wheel 33. The second motor 31 drives the driving wheel 32 and the first grinding roller 34 to rotate, thereby causing the driven wheel 33 and the second grinding roller 35 to rotate synchronously in opposite directions. The grinding effect is achieved through the forward rotation of the first grinding roller 34 and the synchronous reverse rotation of the second grinding roller 35.
[0057] The transmission component 4 includes several parts such as a filter plate 41, a feed pipe 42, a third motor 43, a conveying cylinder 44, a feeding screw 45, and a discharge pipe 46.
[0058] The filter plate 41 is disposed in the grinding chamber 12 at a certain angle, located below the grinding assembly 3, and extends from one side of the grinding chamber 12 to the adjacent side. Preferably, the tilt angle of the filter plate 41 is controlled between 1° and 10°.
[0059] A feed pipe 42 is located at one end of a filter plate 41, extending from one end of the filter plate 41 to the outside of the grinding chamber 12. A conveying cylinder 44 is located outside the grinding chamber 12 and communicates with the feed pipe 42, and a feeding screw 45 is rotatably installed inside it. A third motor 43 is located at the bottom of the conveying cylinder 44, and its drive end passes through the conveying cylinder 44 and extends into the interior of the conveying cylinder 44 to connect with the feeding screw 45. A discharge pipe 46 is located on the conveying cylinder 44, with one end communicating with the conveying cylinder 44 and the other end extending above the first grinding roller 34 and the second grinding roller 35 to communicate with the grinding chamber 12. The discharge pipe 46 is the second channel for copper ore to enter the interior of the machine body 1.
[0060] The copper ore, after being ground by the grinding component 3, falls onto the filter plate 41 under the action of gravity. The qualified copper ore passes through the holes on the filter plate 41 and falls into the collection chamber 13 for collection, while the unqualified copper ore is transported to the conveying cylinder 44 through the feed pipe 42, and then transported to the discharge pipe 46 by the rotating feeding screw 45. The discharge pipe 46 then transports the ore to the first grinding roller 34 and the second grinding roller 35 for further grinding.
[0061] Furthermore, to ensure the quality of the ground copper ore, in this embodiment, the mesh size of the filter plate 41 is controlled between 200 mesh and 325 mesh, that is, the size of the qualified copper ore after grinding is approximately controlled between 0.045 mm and 0.074 mm.
[0062] In specific operation, the copper ore to be crushed is fed into the feed hopper 5. Under the influence of gravity, the copper ore in the feed hopper 5 falls onto the crushing rollers 22. The first motor 21 is started, and the crushing rollers 22 begin to rotate. The two crushing rollers 22 rotate in opposite directions. The crushing rollers 22 use the sheet-like crushing teeth 23 arranged on their outer circumference to squeeze and shear the copper ore, which then enters the grinding chamber 12. The second motor 31 is started, and the first grinding roller 34 rotating in the forward direction and the second grinding roller 35 rotating in the reverse direction squeeze the copper ore. During the squeezing process, the copper ore is ground. After grinding, the copper ore is subjected to gravity... Under the action of the filter plate 41, the copper ore falls onto the filter plate 41, where it is separated into qualified and unqualified copper ore. Qualified copper ore is filtered through the filter plate 41 and collected in the collection chamber 13, while unqualified copper ore remains on the filter plate 41. It then passes through the filter plate 41 at a certain angle and is collected at the feed pipe 42. The feed pipe 42 transports the unqualified copper ore to the conveying cylinder 44, and then the rotating feeding screw 45 transports the copper ore to the discharge pipe 46. The discharge pipe 46 transports the unqualified copper ore to the rotating first grinding roller 34 and second grinding roller 35 for further grinding. This process is repeated until the copper ore is completely ground to the qualified state.
[0063] Furthermore, in order to allow the copper ore to fall slowly onto the crushing roller 22, an opening and closing plate 6 is provided at the bottom of the feed hopper 5. The flow rate of the copper ore can be controlled by controlling the degree of opening and closing of the opening and closing plate 6.
[0064] Furthermore, such as Figure 3As shown, to ensure that the copper ore falls accurately onto the first grinding roller 34 and the second grinding roller 35, and to effectively remove any copper ore residue remaining on the first grinding roller 34 and the second grinding roller 35 due to compression, a first guide block 36 is provided on one inner wall of the grinding chamber 12. One end of the first guide block 36 is fixedly connected to one inner wall of the grinding chamber 12, and the other end extends radially along the first grinding roller 34 until it is close to the first grinding roller 34. Opposite to the first guide block 36, a second guide block 37 is provided on the other inner wall of the grinding chamber 12. One end of the second guide block 37 is fixedly connected to the other inner wall of the grinding chamber 12, and the other end extends radially along the second grinding roller 35 until it is close to the second grinding roller 35. The copper ore entering the grinding chamber 12 through the discharge pipe 46 will be orderly placed between the first grinding roller 34 and the second grinding roller 35 under the guidance of the first guide block 36 and the second guide block 37. Furthermore, since the first guide block 36 and the first grinding roller 34 and the second guide block 37 and the second grinding roller 35 are not in direct contact and have a very small gap between them, when copper ore remains on the first grinding roller 34 and the second grinding roller 35, the rotating first grinding roller 34 and the second grinding roller 35 will cause the residue to fall off under the action of the stationary first guide block 36 and the second guide block 37.
[0065] Furthermore, in order to improve the service life of the first guide block 36 and the second guide block 37, a wear-resistant coating is applied to the outer surface of the first guide block 36 and the second guide block 37. Microcapsules are added to the wear-resistant coating. When wear occurs on the surface of the first guide block 36 and the second guide block 37, the capsules will rupture and release a repair agent. When these repair agents encounter the catalyst in the coating, a cross-linking and curing reaction will occur, thereby repairing the cracked surface and extending the service life of the first guide block 36 and the second guide block 37.
[0066] Furthermore, in order to improve the filtration efficiency of the filter plate 41, a vibrator 7 is provided at the bottom of the filter plate 41. The vibrator 7 causes the filter plate 41 to vibrate, thereby improving the filtration effect.
[0067] Furthermore, to facilitate the removal of copper ore from the collection chamber 13, a collection frame 8 is embedded within the collection chamber 13. When it is necessary to remove qualified copper ore, the qualified copper ore can be removed by pulling the collection frame 8.
[0068] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
