Description

Technical Field

[0001] The invention relates to the technical field of metal recovery, in particular to a crushing and magnetic separation device for recovering scrap metals. Background Art

[0002] The crushing and magnetic separation device for scrap metal recycling usually consists of two major parts: a crushing component and a magnetic separation component. The function of the crushing component is to crush and grind large pieces of scrap metal into smaller particles or fragments, which is helpful for the subsequent separation and processing process. For example, large scrap metal frames, mechanical parts, etc. are crushed into smaller sizes. The magnetic separation component uses magnetic force to adsorb and separate magnetic metal substances. Common magnetic metals such as iron and nickel can be attracted by the magnetic separation component, thereby separating them from non-magnetic substances such as plastics, rubber, glass, etc. For example, iron-containing metal particles can be selected from mixed scrap materials. This crushing and magnetic separation device can improve the efficiency and purity of scrap metal recycling, reduce the workload of manual sorting, and also help scrap metal to be more refined. Processing and reuse, it is of great significance for resource recycling and environmental protection. However, when recycling scrap metal, its composition is by no means limited to iron, cobalt, nickel, and plastics that can be easily separated by magnets.

[0003] In fact, scrap metals usually contain a large amount of aluminum and copper. Given that they have extremely good recyclability and excellent reuse value, the current scrap metal recycling process requires an efficient equipment to effectively separate the various products such as iron, cobalt, nickel, plastic, rubber, copper and aluminum contained therein, so as to achieve complete separation of the various products such as iron, cobalt, nickel, plastic, rubber, copper and aluminum in the scrap metal.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention starts the electric push rod to retract the sealing plate, the first sieve plate and the second sieve plate to the inside. At the same time, when the first sieve plate and the second sieve plate move to the inside of the water filter tank, the non-metallic materials such as plastic and rubber floating on the water surface are clamped between the sealing plate and the first sieve plate, and the first sieve plate and the second sieve plate respectively, until the non-metallic materials such as plastic and rubber floating on the water surface are brought into the water filter tank. In addition, since the first section of the groove inside the limit groove plate is a transverse groove, the sliding knob on the sliding rheostat will not be driven to slide downward by the roller rod during the first forward and backward movement, so that the electromagnetic force generated on the same circuit as the sliding rheostat will not change at this time. When all the non-metallic particles are completely collected in the water filter tank, most of the water on the non-metallic particles is filtered out by the water filtering mechanism, and the generated non-metallic particles are collected, and the non-metallic particles in the waste metal particles are removed at this time.

[0020] The present invention starts the electric push rod again when the non-metallic particles are removed. At this time, when the sealing plate, the first sieve plate and the second sieve plate are in the process of extending forward, the roller rod drives the thumb wheel to rotate counterclockwise because the sealing plate is recovered to the inside of the water filter tank in the previous stage. When the sealing plate moves forward, the thumb wheel cannot rotate clockwise due to the limitation of the limiting wheel by two blocks inside the thumb wheel. When the sealing plate moves forward, the roller rod is driven to move downward along the second groove inside the limiting groove plate. At this time, when the roller rod moves downward, the sliding knob on the sliding rheostat is driven to move downward to reduce the resistance in the circuit, so that the electromagnetic force generated by the sliding rheostat is increased, so that aluminum with a density less than copper floats first. When the reaction time is a certain period of time, the electric push rod is started to recover the sealing plate, the first sieve plate and the second sieve plate inward, so that the aluminum floating on the water can be collected into the water filter tank and collected and recovered by the water filter mechanism, and the sliding knob is driven to descend a part by the roller rod.

[0021] The present invention removes aluminum metal particles in the water at this time, and the roller rod enters the third section groove of the limiting slot plate, so that the resistance in the circuit is reduced again, until the electromagnetic force generated floats the copper on the water, and when it is recovered by the sealing plate, the first sieve plate and the second sieve plate, the floated copper is brought into the water filter tank and recovered by the water filter mechanism. At this time, the sealing plate, the first sieve plate and the second sieve plate extend forward again until the roller rod falls into the bottom of the limiting slot plate. At this time, the resistance is reduced again, so that when the water inside the solution tank is emptied, only the waste metal particles such as iron, cobalt and nickel that will be absorbed by the electromagnetic force are left. At the same time, the remaining metal particles at the bottom of the solution tank are recovered, and the roller rod falls into the vertical groove on the limiting slot plate, and under the action of the limiting spring, the sliding knob is pulled up to the first section of the limiting slot plate, so that the iron, cobalt, nickel, plastic, rubber and other products in the waste metal as well as copper and aluminum can be completely separated by the equipment later;

[0022] In summary, through the coordination of various components, an efficient equipment can effectively separate the various products such as iron, cobalt, nickel, plastic, rubber, copper and aluminum contained therein, so as to facilitate the subsequent processing of recycled metals.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figures 1 to 10 The present invention provides a technical solution of a crushing and magnetic separation device for recycling scrap metals:

[0045] A crushing and magnetic separation device for recycling scrap metals, comprising an equipment support 1, a magnetic field generator 7, a sliding rheostat 9 and a double-shaft motor 2 fixed on the equipment support 1, a crushing mechanism 3 for crushing scrap metals into spherical particles is also arranged on the equipment support 1, a screening mechanism 4 for screening the crushed scrap metals evenly is arranged at the bottom of the crushing mechanism 3, and a magnetic separation mechanism 5 is arranged at the bottom of the screening mechanism 4;

[0046] The magnetic separation mechanism 5 includes a magnetic separation housing 51 and a solution tank 52 for magnetically separating scrap metals and a water filter tank 53 for filtering out moisture from scrap metals, the interior of the water filter tank 53 is fixedly connected with an electric push rod 54 through a fixed base 58, and a controller for receiving signals is arranged inside the electric push rod 54, and a sealing plate 55, a first sieve plate 56 and a second sieve plate 57 are movably connected inside the electric push rod 54, respectively, and circular holes are opened on the first sieve plate 56 and the second sieve plate 57, and the diameter of the circular holes is smaller than the crushed scrap metal, so that the scrap metal after magnetic separation can be brought into the water filter tank 53 when the first sieve plate 56 and the second sieve plate 57 are recycled, and a sealing strip is fixedly connected to the surface of the sealing plate 55 contacting the water filter tank 53, so that the first sieve plate 56 and the second sieve plate 57 will not bring water inside the solution tank 52 into the water filter tank 53 when the first sieve plate 56 and the second sieve plate 57 reciprocate, and both ends of the side of the sealing plate 55 are fixedly connected with a limiting mechanism 8;

[0047] The limiting mechanism 8 includes a limiting slot plate 81 and a roller rod 82 movably connected to the inside of the limiting slot plate 81, and the other end of the roller rod 82 is fixedly connected to the sliding knob on the sliding rheostat 9 so as to automatically adjust the resistance in the circuit. The sliding knob is also fixedly connected to a limiting spring 83 for resetting, and a one-way limiting component 84 is movably connected to the inner bending part of the limiting slot plate 81;

[0048] The one-way limiting assembly 84 includes a dial wheel 841 and a limiting wheel 842 fixed on the dial wheel 841. Two clamping blocks 843 are rotatably connected inside the dial wheel 841, and a reset torsion spring 844 for reset is arranged inside the clamping block 843.

[0049] The magnetic field generator 7 and the sliding rheostat 9 are electrically connected so that the magnitude of the magnetic field generated by the magnetic field generator 7 can be changed by changing the resistance of the sliding rheostat 9 .

[0050] When working, first start the electric push rod 54 inside the water filter tank 53 until the sealing plate 55, the first screen plate 56 and the second screen plate 57 inside the electric push rod 54 are fully extended. At this time, the scrap metal to be crushed is crushed into uniform particles through the crushing mechanism 3, and the mixed particles enter the solution tank 52 from the discharge port of the crushing mechanism 3. When all the crushed scrap metal particles fall into the solution tank 52;

[0051] After a short period of reaction (so that non-metallic materials such as plastics and rubbers with a density lower than that of water can float in water, and non-metallic materials with a small density and a shape close to a sphere can rise and float on the water surface in a few seconds to tens of seconds in static water at room temperature and with normal viscosity, and without the effect of an electromagnetic field), the electric push rod 54 is started to retract the sealing plate 55, the first sieve plate 56 and the second sieve plate 57 inwardly. At the same time, when the first sieve plate 56 and the second sieve plate 57 move toward the inside of the water filter tank 53, the non-metallic materials such as plastics and rubbers floating on the water surface are clamped between the sealing plate 55 and the first sieve plate 56, the first sieve plate 56 and the second sieve plate 57 respectively, until the non-metallic materials such as plastics and rubbers floating on the water surface are brought into the water filter tank 53. In addition, since the first section of the groove inside the limiting groove plate 81 is a transverse groove, the sliding knob on the sliding rheostat 9 will not be driven to slide downward through the roller rod 82 during the first forward and backward movement, so that at this time The magnetic field generator 7 in the same circuit as the sliding rheostat 9 does not work if the current is too small (the magnetic field generator 7 and the sliding rheostat 9 are simply connected in series, so that when the sliding knob on the sliding rheostat 9 moves downward, the resistance in the circuit is increased to increase the current, and the electromagnetic force generated by the magnetic field generator 7 is increased by increasing the current. The magnetic field generator 7 uses a three-dimensional coil, model 3HLY15-30, the magnetic field directions X axis, Y axis, and Z axis are mutually orthogonal, the maximum magnetic field intensity of each axis is 30Gs, the minimum average diameter is 300mm, the diameter of the uniform area sphere is 40mm, the uniformity is 0.1%, and the power supply is 120W per axis. It only plays a role in changing the magnetic field intensity change inside the solution tank 52, which is common knowledge in the field and will not be described in detail here). When all the non-metallic particles are completely collected in the water filter tank 53, most of the water on the non-metallic particles is filtered out by the water filter mechanism 10, and the generated non-metallic particles are collected. At this time, the non-metallic particles in the waste metal particles are removed;

[0052] When the non-metallic particles are removed, the electric push rod 54 is started again. At this time, when the sealing plate 55, the first sieve plate 56 and the second sieve plate 57 are extending forward, the roller rod 82 drives the thumbwheel 841 to rotate counterclockwise when the sealing plate 55 is recovered to the inside of the water filter tank 53 in the previous stage. When the sealing plate 55 moves forward, the thumbwheel 841 cannot rotate clockwise due to the limitation of the limiting wheel 842 by the two blocks 843 inside the thumbwheel 841. When the sealing plate 55 moves forward, the roller rod 82 is driven to move downward along the second groove inside the limiting groove plate 81. At this time, when the roller rod 82 moves downward, the sliding knob on the sliding rheostat 9 is driven downward to reduce the resistance in the circuit, so that the electromagnetic force generated by the sliding rheostat 9 increases. (The density of aluminum is about 2.7g / cm³, and the density of copper is about 8.96g / cm³. Aluminum is relatively lighter and may be more susceptible to upward force to float up), so that the aluminum with a density lower than that of copper will float up first, (when the electromagnetic field acts on the metal, an induced current will be generated inside the metal. According to Lenz's law, the magnetic field generated by the induced current will resist the change of the magnetic field causing the induced current. This resistance will cause the metal to be subjected to an upward electromagnetic force. If this upward electromagnetic force is greater than the sum of the gravity exerted on the metal and the buoyancy and resistance in the water, the metal will begin to float up), when the reaction time is certain (at this time the water is still and uniform, the electromagnetic field is stable and uniform, the shape of the aluminum block is regular, and the volume and mass of the aluminum block are moderate. In this case, it only takes a few seconds to tens of seconds for the aluminum to rise and float on the water surface), the electric push rod 54 is started to retract the sealing plate 55, the first screen plate 56 and the second screen plate 57 inward, so that the aluminum floating on the water can be collected into the water filter tank 53, and collected and recycled by the water filter mechanism 10, and the sliding knob is driven to descend a part by the roller rod 82;

[0053] At this time, when the aluminum metal particles in the water are removed, the roller rod 82 enters the third groove of the limiting slot plate 81, so that the resistance in the circuit is reduced again, until the electromagnetic force generated floats the copper on the water, and when it is recovered by the sealing plate 55, the first sieve plate 56 and the second sieve plate 57, the floating copper is brought into the water filter tank 53 and recovered by the water filter mechanism 10. At this time, the sealing plate 55, the first sieve plate 56 and the second sieve plate 57 extend forward again until the roller rod 82 falls into the bottom of the limiting slot plate 81. At this time, the resistance is reduced again, so that when the water in the solution tank 52 is emptied, only the scrap metal particles such as iron, cobalt, and nickel that will be attracted by the electromagnetic force are left, and the remaining metal particles at the bottom of the solution tank 52 are recovered, and the roller rod 82 falls into the vertical slot on the limit slot plate 81, and the sliding knob is pulled up to the first section of the limit slot plate 81 under the action of the limit spring 83, so that the iron, cobalt, nickel, plastic, rubber and other products as well as copper and aluminum in the scrap metal can be completely separated by the equipment later;

[0054] In summary, through the coordination of various components, an efficient equipment can effectively separate the various products such as iron, cobalt, nickel, plastic, rubber, copper and aluminum contained therein, so as to facilitate the subsequent processing of recycled metals.

[0055] As an embodiment of the present invention, Figure 2 Figure 3 and Figure 4 As shown, the crushing mechanism 3 includes a supporting chassis 31 and two crushing blade rollers 32 rotatably connected to the inside of the supporting chassis 31, and a driving gear 33 fixedly connected to the two crushing blade rollers 32 is provided on the side of the supporting chassis 31, and a driving shaft 34 is fixedly connected to one of the driving gears 33, and the driving shaft 34 is fixedly connected to one of the output shafts of the dual-axis motor 2.

[0056] During operation, the waste is placed in the carrying chassis 31, and the driving shaft 34 is driven to rotate by the dual-axis motor 2. When the driving shaft 34 rotates, it drives the two crushing rollers 32 to rotate and engage, so that the waste is crushed into uniform iron, cobalt, nickel, plastic, rubber and other products as well as copper and aluminum metal spherical particles, so as to facilitate the subsequent separation and recovery of metals and non-metals.

[0057] As an embodiment of the present invention, Figure 2 Figure 3 and Figure 4 As shown, the screening mechanism 4 includes a screen plate 41 and two cam shafts 44 rotatably connected to both sides of the equipment bracket 1. A plurality of equidistantly arranged screen holes 42 are provided inside the screen plate 41 so that the crushed scrap metal can pass through the screen plate 41 evenly. One end of the two cam shafts 44 is fixedly connected to a meshing gear 45, and the two meshing gears 45 are connected by a transmission chain 46 so that the screen plate 41 can be driven to vibrate up and down when the two cam shafts 44 rotate. Four elastic components 43 are fixedly connected to the four ends of the screen plate 41, and the other ends of the four elastic components 43 are fixedly connected to the bottom of the supporting chassis 31 so that the screen plate 41 can spread the crushed scrap metal evenly.

[0058] During operation, when the waste is crushed, the mixed particles will preferentially fall onto the sieve plate 41 from the bottom of the supporting chassis 31, and a meshing gear 45 is driven to rotate by the dual-axis motor 2 under the action of the transmission mechanism 6, and another meshing gear 45 is driven to rotate under the action of the transmission chain 46, and the camshaft 44 on the meshing gear 45 is driven to rotate at the same time, so that when the camshaft 44 rotates, the sieve plate 41 can be driven to vibrate up and down under the limit of the elastic component 43, so that the mixed material particles falling on the sieve plate 41 can pass through the sieve hole 42 evenly, so that the crushed scrap metal particles can be evenly distributed and fall into the interior of the solution tank 52, so as to prevent metal agglomeration and thus press the non-metal to the bottom of the solution tank 52, so as to facilitate the subsequent separation of various products such as iron, cobalt, nickel, plastic, rubber and copper and aluminum metal particles.

[0059] As an embodiment of the present invention, Figure 2 Figure 3 and Figure 4 As shown, the crushing mechanism 3 and the screening mechanism 4 are connected through a transmission mechanism 6, and the transmission mechanism 6 includes a transmission wheel 1 61 fixedly connected to the other output shaft of the dual-axis motor 2, and the transmission wheel 1 61 is connected to the transmission wheel 2 63 through a transmission belt 62, and the transmission wheel 2 63 is fixedly connected to a grooved gear 64 for meshing with a transmission chain 46, and the transmission wheel 2 63 is movably connected to a bearing seat 65, so that when the grooved gear 64 rotates, the transmission chain 46 is driven to rotate, and the inner side of the equipment bracket 1 is also fixedly connected to a bearing seat 65 rotatably connected to the other end of the grooved gear 64, so that the grooved gear 64 will not tilt when it meshes with the meshing gear 45.

[0060] During operation, when the dual-axis motor 2 is started, one of the output shafts of the dual-axis motor 2 drives the transmission wheel 1 61 to rotate, and the other output shaft drives the crushing mechanism 3 to rotate. At this time, the transmission wheel 1 61 drives the transmission wheel 2 63 to rotate through the transmission belt 62, and the transmission wheel 2 63 is fixedly connected with a grooved gear 64 for meshing with the meshing gear 45, so that the crushing mechanism 3 and the screening mechanism 4 can work synchronously when the dual-axis motor 2 is started, so that after crushing, the crushed mixed particles can be quickly and evenly discharged into the solution tank 52 to increase the floating speed of the mixed particles.

[0061] As an embodiment of the present invention, Fig. 9As shown, a water filtering mechanism 10 is also provided inside the magnetic separation shell 51, and the water filtering mechanism 10 includes a material box 101 for recycling scrap metal, and a handle 102 for pulling is fixedly connected to the front end of the material box 101, a drainage groove 103 is provided at the bottom of the magnetic separation shell 51, and a transverse groove matching the drainage groove 103 is provided at the bottom of the material box 101, and a sliding component 104 for sliding the material box 101 is fixedly connected between the material box 101 and the magnetic separation shell 51.

[0062] During operation, when various products such as iron, cobalt, nickel, plastic, rubber, and copper and aluminum metal particles are brought into the water filter trough 53 by the sealing plate 55, the first sieve plate 56, and the second sieve plate 57, the collected particles will fall onto the material box 101, and a large amount of water on the particles will be filtered out through the transverse grooves and the drainage grooves 103 of the material box 101, and by pulling the handle 102 under the action of the sliding assembly 104, the metal particles recovered inside can be pulled out to achieve the purpose of metal recovery.

[0063] Working principle: When working, the waste is placed in the carrier case 31, and the driving shaft 34 is driven to rotate by the dual-axis motor 2. When the driving shaft 34 rotates, it drives the two crushing knife rollers 32 to rotate and mesh, so that the waste is crushed into uniform iron, cobalt, nickel, plastic, rubber and other products as well as copper and aluminum metal particles. When the mixed particles fall on the screen plate 41 from the bottom of the carrier case 31, when the dual-axis motor 2 is started, one of the output shafts of the dual-axis motor 2 drives the transmission wheel 1 61 to rotate, and the other output shaft drives the crushing mechanism 3 to rotate. At this time, the transmission wheel 1 61 drives the transmission wheel 2 63 to rotate through the transmission belt 62, and the transmission wheel 2 63 is fixedly connected with a grooved gear 64 for meshing with the meshing gear 45, so that when the dual-axis motor 2 is started, the crushing mechanism 3 and the screening machine The structure 4 can work synchronously, so that after the crushing, the crushed mixed particles can be quickly and evenly discharged into the solution tank 52 to increase the floating speed of the mixed particles, and the dual-axis motor 2 drives a meshing gear 45 to rotate under the action of the transmission mechanism 6, and drives another meshing gear 45 to rotate under the action of the transmission chain 46, and drives the camshaft 44 on the meshing gear 45 to rotate at the same time, so that when the camshaft 44 rotates, it can drive the screen plate 41 to vibrate up and down under the limit of the elastic component 43, so that the mixed material particles falling on the screen plate 41 can pass through the sieve hole 42 evenly, so that the crushed scrap metal particles can be evenly distributed and fall into the interior of the solution tank 52, when all the crushed scrap metal particles fall into the solution tank 52;

[0064] After a short period of reaction, the electric push rod 54 is started to make the sealing plate 55, the first sieve plate 56 and the second sieve plate 57 retracted to the inside. At the same time, when the first sieve plate 56 and the second sieve plate 57 move to the inside of the water filter tank 53, the non-metallic materials such as plastic and rubber blocking the water surface are clamped between the sealing plate 55 and the first sieve plate 56, the first sieve plate 56 and the second sieve plate 57 respectively, until the non-metallic materials such as plastic and rubber floating on the water surface are brought into the water filter tank 53. In addition, since the first section of the groove inside the limit groove plate 81 is a transverse groove, the sliding knob on the sliding rheostat 9 will not be driven to slide downward through the roller rod 82 during the first forward and backward movement, so that the electromagnetic force generated on the same circuit as the sliding rheostat 9 will not change at this time. When all the non-metallic particles are completely collected in the water filter tank 53, most of the water on the non-metallic particles is filtered out by the water filtering mechanism 10, and the generated non-metallic particles are collected. At this time, the non-metallic particles in the waste metal particles are removed;

[0065] When the non-metallic particles are removed, the electric push rod 54 is started again. At this time, when the sealing plate 55, the first sieve plate 56 and the second sieve plate 57 are extending forward, the roller rod 82 drives the thumbwheel 841 to rotate counterclockwise when the sealing plate 55 is retracted into the water filter tank 53 in the previous stage. When the sealing plate 55 moves forward, the thumbwheel 841 cannot rotate clockwise due to the two blocks 843 inside the thumbwheel 841 limiting the limit wheel 842. When the sealing plate 55 moves forward, the roller rod 82 is driven along the limit groove plate 843 to move along the limit groove plate 843. 1 moves downward, and at this time, the sliding knob on the sliding rheostat 9 is driven to move downward while the roller rod 82 moves downward, so as to reduce the resistance in the circuit, thereby increasing the electromagnetic force generated by the sliding rheostat 9, so that the aluminum with a density less than that of copper floats first. When the reaction time is a certain period, the electric push rod 54 is started to retract the sealing plate 55, the first sieve plate 56 and the second sieve plate 57 inward, so that the aluminum floating on the water can be collected into the water filter tank 53 and collected and recycled by the water filter mechanism 10, and the sliding knob is driven to descend a part by the roller rod 82;

[0066] At this time, when the aluminum metal particles in the water are removed, the roller rod 82 enters the third groove of the limiting slot plate 81, so that the resistance in the circuit is reduced again, until the electromagnetic force generated floats the copper on the water, and when it is recovered by the sealing plate 55, the first sieve plate 56 and the second sieve plate 57, the floating copper is brought into the water filter tank 53 and recovered by the water filter mechanism 10. At this time, the sealing plate 55, the first sieve plate 56 and the second sieve plate 57 extend forward again until the roller rod 82 falls into the bottom of the limiting slot plate 81. At this time, the resistance is reduced again, so that when the water in the solution tank 52 is emptied, only the scrap metal particles such as iron, cobalt, and nickel that will be attracted by the electromagnetic force are left, and the remaining metal particles at the bottom of the solution tank 52 are recovered, and the roller rod 82 falls into the vertical slot on the limit slot plate 81, and the sliding knob is pulled up to the first section of the limit slot plate 81 under the action of the limit spring 83, so that the iron, cobalt, nickel, plastic, rubber and other products as well as copper and aluminum in the scrap metal can be completely separated by the equipment later;

[0067] In summary, through the coordination of various components, an efficient equipment can effectively separate the various products such as iron, cobalt, nickel, plastic, rubber, copper and aluminum contained therein, so as to facilitate the subsequent processing of recycled metals.
