[0020] 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.

[0021] Example 1: Figure 1-Figure 5 As shown, a pelletizer for processing scrap metals includes a fixed box 100, a crushing mechanism 110, a driving mechanism 120, a cooling mechanism 130 and a pelletizing mechanism 200.

[0022] The top and bottom of the fixed box 100 are both open. The crushing mechanism 110 includes a rotating drum 111, three baffles 115 and a crushing assembly. The rotating drum 111 is rotatably connected to the fixed box 100; the three baffles 115 are equidistantly installed on the inner wall of the rotating drum 111; the crushing assembly is installed in the rotating drum 111, and the crushing assembly is used to crush the scrap metal.

[0023] The driving mechanism 120 is used to drive the pulverizing assembly to operate and drive the drum 111 to rotate; the cooling mechanism 130 is used to reduce the temperature of the scrap metal in the pulverizing mechanism 110; the agglomeration mechanism 200 is installed below the fixed box 100, and the agglomeration mechanism 200 is used to receive the pulverized scrap metal discharged by the pulverizing mechanism 110 and agglomerate the pulverized scrap metal.

[0024] Specifically, by adding scrap metal into the drum 111 and starting the driving mechanism 120, the crushing assembly and the drum 111 are driven to run. When the crushing assembly is running, the scrap metal is crushed, and the crushed scrap metal falls to the bottom of the crushing assembly. As the drum 111 rotates, the drum 111 transports the metal below the crushing assembly upward through the baffle 115, so that the part of the metal falls into the crushing assembly again, and the crushing assembly crushes the scrap metal again, and so on and so forth, so as to completely crush the scrap metal.

[0025] Then, the crushed scrap metal is added into the agglomeration mechanism 200, so that the agglomeration mechanism 200 agglomerates the crushed scrap metal fragments, thereby obtaining metal pellets.

[0026] like Figure 4-Figure 6 As shown, the pulverizing mechanism 110 further includes a plurality of teeth 1112, a first fixed plate 112, a feeding pipe 113 and a second fixed plate 114. The plurality of teeth 1112 are equidistantly mounted on the outer surface of the drum 111; the first fixed plate 112 is fixedly connected to the inner wall of the fixed box 100, the first fixed plate 112 is rotatably connected to the drum 111, and the first fixed plate 112 is a circular plate. The feeding pipe 113 is installed through the first fixed plate 112; the second fixed plate 114 is fixedly connected to the inner wall of the fixed box 100, the second fixed plate 114 is rotatably connected to the drum 111, and the second fixed plate 114 is a circular plate.

[0027] Specifically, the scrap metal to be processed is added into the drum 111 through the feeding pipe 113. When the teeth 1112 move, the drum 111 is driven to rotate. Since the drum 111 is provided with a baffle 115, the baffle 115 drives the scrap metal in the drum 111 to move.

[0028] like Figure 4 and Figure 5 As shown, the pulverizing mechanism 110 further includes two discharge chutes, two hinged plates 1111 , two multi-stage electric push rods 116 and an extrusion block 117 .

[0029] Both discharge troughs are opened on the rotating drum 111; both hinged plates 1111 are hinged to the rotating drum 111, and the two hinged plates 1111 are respectively located in the two discharge troughs; both multi-stage electric push rods 116 are installed on the outer surface of the rotating drum 111; the extrusion block 117 is fixedly connected to the extended ends of the two multi-stage electric push rods 116, and the extrusion block 117 is in contact with the two hinged plates 1111.

[0030] Specifically, when the scrap metal in the drum 111 needs to be discharged, the drum 111 is first rotated so that the two hinged plates 1111 are located below the drum 111, and then the two multi-stage electric push rods 116 are started to drive the extrusion block 117 to move away from the drum 111. At this time, under the influence of gravity, the two hinged plates 1111 will rotate, causing the hinged plates 1111 to no longer be tightly connected to the discharge chute, and the scrap metal in the drum 111 will slide along the slope of the hinged plates 1111, and the metal scraps will be discharged from the drum 111 and fall into the agglomeration mechanism 200.

[0031] like Figure 6 and Figure 7 As shown, the pulverizing assembly includes two cross bars 118, two pulverizing rollers 1181 and two first gears 119. The two cross bars 118 are both rotatably connected to the first fixed plate 112 and the second fixed plate 114; the two pulverizing rollers 1181 are both located in the rotating drum 111, and the two pulverizing rollers 1181 are respectively fixedly sleeved on the two cross bars 118; the two first gears 119 are respectively fixedly sleeved on the parts of the two cross bars 118 located outside the rotating drum 111, and the two first gears 119 are meshed and connected.

[0032] Specifically, when any crossbar 118 rotates, the other crossbar 118 will be driven to rotate through the two first gears 119, thereby causing the two crushing rollers 1181 to rotate simultaneously, and because the two crossbars 118 are connected through the two first gears 119, the two crossbars 118 rotate in opposite directions. When scrap metal falls between the two crushing rollers 1181, the two rotating crushing rollers 1181 will crush the scrap metal.

[0033] like Figure 4 and Figure 7 As shown, the driving mechanism 120 includes a first motor 121, a driving gear 122 and a chain 123. The first motor 121 is installed in the fixed box 100; the driving gear 122 is installed on the power output shaft of the first motor 121, and the driving gear 122 is meshed and connected with the teeth 1112; a sprocket is fixedly sleeved on the power output shaft of the first motor 121, a sprocket is fixedly sleeved on any cross bar 118, and the chain 123 is sleeved on two sprockets.

[0034] Specifically, when the first motor 121 is running, it will drive the driving gear 122 to rotate, and then mesh with and drive the teeth 1112 on the rotating drum 111 to rotate, thereby driving the rotating drum 111 to rotate. When the first motor 121 is running, it will also drive a cross bar 118 to rotate through the chain 123, and then drive another cross bar 118 to rotate through the two first gears 119.

[0035] like Figure 2 , Figure 4 and Figure 7As shown, the cooling mechanism 130 includes a rotating shaft 131, a pinion 132, a fan blade 133 and an air guide cover 134. The rotating shaft 131 is rotatably mounted on the second fixed plate 114; the pinion 132 is fixedly sleeved on the rotating shaft 131, and the pinion 132 is meshedly connected with the driving gear 122; the fan blade 133 is mounted on the rotating shaft 131; the air guide cover 134 is mounted on the fixed box 100, and the other end of the air guide cover 134 extends into the rotating drum 111, and the fan blade 133 is located in the air guide cover 134.

[0036] Specifically, when the crossbar 118 rotates, it drives the first gear 119 to rotate, and the rotating first gear 119 meshes and drives the pinion 132 to rotate rapidly, thereby driving the rotating shaft 131 and the fan blades 133 to rotate rapidly, and the rotating fan blades 133 blow the outside air into the wind guide cover 134, and the air in the wind guide cover 134 will be transported to the drum 111, thereby accelerating the flow of air in the drum 111, thereby facilitating the cooling of the scrap metal in the drum 111. The higher the temperature of the metal, the better the toughness and ductility, and the less likely the metal is to be crushed; and the lower the temperature of the metal, the harder and more brittle it will be, and the easier it will be to be crushed.

[0037] like Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, the pelletizing mechanism 200 includes a bottom box 201 , two hydraulic cylinders 202 , a connecting plate 203 , a blocking plate 204 , a mounting block 205 , a second motor 206 , a pelletizing plate 207 and two support frames 208 .

[0038] The bottom box 201 is installed on the bottom surface of the fixed box 100, and the top and bottom surfaces of the bottom box 201 are both open; the two hydraulic cylinders 202 are installed on the surface of the bottom box 201; the connecting plate 203 is installed on the extended ends of the two hydraulic cylinders 202; the blocking plate 204 is installed on the top surface of the connecting plate 203, and the blocking plate 204 is used to block the bottom opening of the bottom box 201; the mounting block 205 is installed on the inner wall of the bottom box 201, and the cross-section of the mounting block 205 is triangular. By setting the mounting block 205 of this shape, it is possible to avoid the accumulation of scrap metal fragments on the mounting block 205.

[0039] The second motor 206 is installed on the bottom surface of the mounting block 205 ; the pellet plate 207 is installed on the power output shaft of the second motor 206 ; and the two support frames 208 are both fixedly connected to the bottom box 201 .

[0040] Specifically, when the crushed scrap metal falls to the bottom of the bottom box 201, the crushed metal will fall on the blocking plate 204. By starting the second motor 206, the power output shaft of the second motor 206 drives the pellet plate 207 to rotate, and the rotating pellet plate 207 cooperates with the blocking plate 204 to pelletize the scrap metal. After the pelletization is completed, the two hydraulic cylinders 202 are started to drive the connecting plate 203 and the blocking plate 204 to move downward, thereby separating the blocking plate 204 from the bottom box 201, so as to facilitate the removal of the metal pellets on the top surface of the blocking plate 204.

[0041] Working principle: When in use, scrap metal is added into the rotating drum 111 through the feeding pipe 113, and the first motor 121 is started, so that the power output shaft of the first motor 121 drives a cross bar 118 to rotate through the chain 123. Since the two cross bars 118 are connected by the first gear 119, when one cross bar 118 rotates, the other cross bar 118 will also rotate. When the two cross bars 118 rotate, they will drive the two crushing rollers 1181 to rotate. The two rotating crushing rollers 1181 will crush the scrap metal, and the crushed scrap metal will fall to the bottom of the crushing assembly.

[0042] When the first motor 121 is running, it will also drive the driving gear 122 to rotate, and then mesh and drive the teeth 1112 to rotate, and then drive the rotating drum 111 to rotate. As the rotating drum 111 rotates, the rotating drum 111 will transport the metal located on the crushing roller 1181 upward through the baffle 115, so that this part of the metal falls between the two crushing rollers 1181 again, and the two rotating crushing rollers 1181 crush the scrap metal again, and so on and so forth, so that the scrap metal is completely crushed.

[0043] After the scrap metal is crushed, when the hinge plate 1111 on the drum 111 is located at the bottom, the second motor 206 is turned off to stop the operation of the drum 111.

[0044] By starting the two multi-stage electric push rods 116, the extrusion block 117 is driven to move away from the rotating drum 111. At this time, under the influence of gravity, the two hinged plates 1111 will rotate, so that the two hinged plates 1111 are no longer tightly connected to the discharge chute, and the scrap metal in the rotating drum 111 will slide along the slope of the hinged plates 1111, and the scrap metal fragments will be discharged from the rotating drum 111 and fall into the bottom box 201.

[0045] The crushed metal scraps will fall on the blocking plate 204. By starting the second motor 206, the power output shaft of the second motor 206 drives the pelletizing plate 207 to rotate. The rotating pelletizing plate 207 cooperates with the blocking plate 204 to pelletize the scrap metal. After the pelletizing is completed, the two hydraulic cylinders 202 are started to drive the connecting plate 203 and the blocking plate 204 to move downward, thereby separating the blocking plate 204 from the bottom box 201, so as to facilitate the removal of the metal pellets on the top surface of the blocking plate 204.

[0046] Among them, when the scrap metal is crushed, the power output shaft of the second motor 206 will drive the cross bar 118 and the first gear 119 to rotate through the chain 123, and the rotating first gear 119 will engage and drive the pinion 132 to rotate rapidly, thereby driving the rotating shaft 131 and the fan blades 133 to rotate rapidly, and the rotating fan blades 133 will blow the outside air into the wind guide cover 134, and the air in the wind guide cover 134 will be transported to the rotating drum 111, thereby accelerating the flow of air in the rotating drum 111, so as to facilitate cooling of the scrap metal in the rotating drum 111. The lower the temperature of the metal, the harder and more brittle it will be, and the easier it will be to be crushed, thereby facilitating improving the efficiency of crushing the scrap metal.

[0047] Example 2: Figure 1-Figure 9 As shown, a working method of a pelletizer for scrap metal processing comprises the following steps: Step 1: Check whether all parts of the pelletizer are intact, and ensure that the driving mechanism 120, the crushing mechanism 110, the cooling mechanism 130 and the pelletizing mechanism 200 are in normal condition; prepare the scrap metal raw materials and ensure that the scrap metal is dry; Step 2: Start the first motor 121 of the driving mechanism 120, so that the power output shaft of the first motor 121 drives the driving gear 122 to rotate, and then drives the rotating drum 111 to rotate through the teeth 1112. At the same time, the first motor 121 also drives the crushing assembly to operate through the chain 123; Step 3: Add the scrap metal raw materials into the drum 111 through the feeding pipe 113. As the driving mechanism 120 operates, the two crushing rollers 1181 in the crushing assembly start to rotate relatively, thereby crushing the scrap metal in the drum 111. At the same time, the drum 111 rotates under the action of the driving mechanism 120, and the crushed scrap metal is transported upward through the baffle 115 on the inner wall, so that the metal falls again between the crushing rollers 1181 for crushing again, and this cycle repeats until the scrap metal is completely crushed. Step 4: During the crushing process, the rotating first gear 119 drives the pinion 132 to rotate rapidly, thereby causing the rotating shaft 131 and the fan blades 133 to rotate rapidly and generate airflow, and then the outside air is introduced into the drum 111 through the air guide cover 134 to cool the scrap metal during the crushing process; Step 5: When the scrap metal is crushed to a predetermined degree, the driving mechanism 120 is stopped, the multi-stage electric push rod 116 is started, and the extrusion block 117 is pushed to move, so that the hinge plate 1111 opens the discharge chute, and the crushed scrap metal is discharged from the drum 111 through the discharge chute under the action of gravity, so that the crushed metal falls into the pelletizing mechanism 200; Step 6: Start the second motor 206 in the agglomeration mechanism 200 to drive the agglomeration plate 207 to rotate, and the rotating agglomeration plate 207 cooperates with the blocking plate 204 to agglomerate the metal scraps into metal pellets; Step 7: After the pelletizing is completed, the hydraulic cylinder 202 is started to push the connecting plate 203 and the blocking plate 204 downward to separate the blocking plate 204 from the bottom box 201 and remove the metal pellets on the blocking plate 204.
