Description

Technical Field

[0001] The present invention relates to the technical field of scrap metal processing equipment, and more specifically, to scrap metal finishing equipment and a scrap metal processing system. Background Art

[0002] In the current scrap metal processing field, crushers are usually used to crush and process light and thin scrap metal materials. Large-sized light and thin scrap metal materials are crushed into broken materials of a certain size by the crusher, and then compressed into bales that meet the size requirements of the steel plant by the baler.

[0003] The main working part of the universal crusher is a main shaft roller that rotates at high speed in the working chamber of the machine body. A crushing hammer head and a pattern roller are installed on the outside of the main shaft roller. After large-sized materials enter the feed port of the machine body, they are hit and crushed by the high-speed rotating crushing hammer head and pattern roller, and are gradually broken into pieces. When the size of the fragments is smaller than the size of the screen holes at the bottom of the machine body, they are discharged from the machine body through the holes, completing the crushing process.

[0004] The materials processed by the crusher are usually uniform in size and meet customer requirements. However, since the materials are crushed into a certain size and then discharged from the machine body, the processing time is short, and metal rust, surface paint film, and sticky sludge are often not effectively removed.

[0038] The scrap metal finishing equipment and scrap metal processing system provided by the present invention are explained and illustrated in detail below in conjunction with the accompanying drawings of the specification.

[0039] The scrap metal finishing equipment and scrap metal processing system provided by the present invention are mainly used to process light and thin scrap metal materials. The crushed scrap metal is further refined in the scrap metal finishing equipment, so that the scrap metal is fully kneaded by the kneading components and the kneading structure in the processing channel to remove the paint film, rust, sludge, etc. adhered to the metal surface, thereby improving the quality of the scrap metal after processing, and further improving the economic value of the scrap metal. In addition, the present invention can further crush the scrap metal during the process of refining the scrap metal, so that the size of the scrap metal after processing is smaller, and the bulk density of the scrap metal after processing is increased. The present invention is described in detail below in conjunction with specific embodiments:

[0040] The present invention provides a scrap metal finishing equipment, such as Figure 2 , Figure 3 As shown, it includes: a box body 1 and a spindle roller 2 arranged on the box body 1, wherein a cylindrical cavity is formed in the box body 1, an inner lining plate 13 is arranged on the inner wall of the box body 1, and a kneading structure is formed on the inner lining plate 13; Figure 5 The spindle roller 2 shown includes a spindle 21 and a kneading assembly arranged on the spindle 21, the spindle 21 is rotatably arranged on the box body 1, the kneading assembly is located in the cavity and rotates with the spindle 21; a feed port 111 and a discharge port connected to the cavity are formed on the box body 1, the feed port 111 and the discharge port are respectively arranged near the two ends of the spindle 21, and the part of the cavity located between the feed port 111 and the discharge port constitutes a processing channel extending along the axial direction of the spindle roller 2; when the spindle roller 2 rotates, the scrap metal moves between the kneading assembly and the inner lining plate 13 and is kneaded and knocked.

[0041] The scrap metal of the present invention moves in the processing channel, and is kneaded by the kneading assembly and the kneading structure on the inner lining plate 13 during the movement, thereby removing various stains on the metal surface. And because the feed port 111 and the discharge port on the box body 1 are respectively arranged close to the two ends of the main shaft 21, the processing channel time can be effectively extended, thereby extending the time for the scrap metal to move in the processing channel, that is, extending the time for the scrap metal to be kneaded, and further enabling the scrap metal to be kneaded more fully, ensuring that impurities such as paint film, rust, and sludge on the surface of the scrap metal can be effectively removed. In addition, in the process of being processed in the processing channel, the scrap metal with a relatively large size will be broken into smaller pieces again, or the loose scraps will be kneaded and compressed to form compact scrap blocks, thereby increasing the stacking density.

[0042] Optionally, the kneading structure is a groove and / or convex structure formed on the inner lining plate 13. In this embodiment, the inner lining plate 13 is formed of a wear-resistant metal material and is in an arc shape that can fit on the inner circumferential wall of the box body 1. The outer convex surface of the arc fits on the inner circumferential wall of the box body 1, and a plurality of grooves are formed on the inner concave surface, and the plurality of grooves are evenly distributed. For example, Figure 4 As shown, the groove is a structure in which the width dimension gradually decreases from the opening to the bottom of the groove, so that a tooth-shaped structure with a narrow upper part and a wide lower part is formed between two adjacent grooves, so that the contact surface between the kneading structure and the scrap metal is smaller, thereby improving the kneading effect.

[0043] Furthermore, the inner lining plate 13 can be set as a multi-piece splicing structure in the circumferential direction and in the axial direction, so as to facilitate partial replacement. For example, it can be divided into multiple sections in the axial direction, and each section of the inner lining plate 13 is independently installed on the inner circumferential wall of the box body 1, and can be detachably connected by screws and other connectors, so as to facilitate replacement. Optionally, the kneading structures on multiple inner lining plates are spliced ​​to form a continuous groove. Furthermore, the groove extends along a spiral line with the axis of the cavity as the central axis, so as to guide the movement of the scrap metal in the processing channel, so that the scrap metal can move around the main shaft roller 2 along the spiral movement route, so as to further extend the movement route of the scrap metal in the processing channel, and further extend the time for the scrap metal to be kneaded and processed.

[0044] like Figure 5 , Figure 6 As shown, the kneading assembly includes a fixed disc 22, and a plurality of fixed discs 22 are distributed along the axial direction of the main shaft 21 and fixedly arranged on the main shaft 21. For example, a connecting hole is arranged at the center of the fixed disc 22, and the fixed disc 22 is sleeved on the main shaft 21 through the connecting hole. The connecting hole and the main shaft 21 can be fixedly connected by interference fit so that the fixed disc 22 and the main shaft 21 rotate synchronously. Optionally, a spacer 26 is arranged between two adjacent fixed discs 22, and the spacer 26 is sleeved on the main shaft 21. The spacer 26 is arranged to ensure that the spacing between two adjacent fixed discs 22 is the same.

[0045] A plurality of axial holes are distributed along the circumference of the fixed disc 22, and a pin 23 is inserted into the axial hole. A kneading hammer 24 and / or a kneading wheel 25 are arranged between two adjacent fixed discs 22, and the kneading hammer 24 and the kneading wheel 25 are rotatably arranged on the pin 23. In the present embodiment, the kneading hammer 24 is an eccentric block, and its connection hole with the pin 23 is offset on one side. When the main shaft 21 rotates, the hammer head of the kneading hammer 24 is thrown out to the radial outer side of the fixed disc 22 to beat the scrap metal. The kneading wheel 25 is a roller, and kneading teeth are arranged on the outer edge of the roller, and the kneading teeth are evenly distributed along the circumference of the roller. The roller is rotatably arranged on the pin 23, and the kneading teeth extend outward from the radial outer side of the fixed disc 22. When the main shaft 21 rotates, the kneading teeth on the roller contact with the scrap metal and can crush the scrap metal. The kneading teeth and the kneading hammers 24 cooperate with the inner lining plate 13 to strike and crush the scrap metal, causing the scrap metal to deform and vibrate multiple times, thereby achieving a kneading effect, thereby causing the paint film, rust, etc. adhering to the scrap metal to fall off.

[0046] In this embodiment, a kneading hammer 24 and a plurality of kneading wheels 25 are arranged between two adjacent fixed discs 22. Optionally, two adjacent kneading hammers 24 in the axial direction are staggered with each other. Furthermore, the plurality of kneading hammers 24 are distributed along a spiral line with the center line of the main shaft 21 as the axis, so that the scrap metal can be struck by the kneading hammers 24 as many times as possible during the movement in the processing channel.

[0047] Optionally, in other embodiments, any one or more of the kneading structure on the inner lining plate 13 and the kneading hammer 24 and the kneading wheel 25 can be set to a structure distributed along a spiral line and can be used in combination. For example, the kneading hammer 24 is distributed along a spiral line with the center line of the main shaft 21 as the axis, and the kneading structure on the inner lining plate 13 and the kneading wheel 25 on the main shaft can be distributed in any manner; or, the kneading hammer 24 and the kneading wheel 25 are distributed in any manner, and the kneading structure on the inner lining plate 13 is set to a structure extending and distributed along the spiral line with the axis of the cavity as the center axis; or, multiple kneading hammers 24 are arranged in a conventional symmetrical manner, and the kneading structure and the kneading wheel 25 on the inner lining plate 13 are distributed in any manner; further, the kneading wheel 25 can also be set to a structure distributed along a spiral line with the center line of the main shaft 21 as the axis, and the kneading hammer 24 and the kneading structure on the inner lining plate 13 can be set to be distributed in any manner. Thereby, the moving time of the scrap metal in the processing channel can be further extended. The four distribution conditions can guide the movement of scrap metal and extend the movement path of scrap metal to a certain extent, thereby enhancing the rubbing effect on the scrap metal.

[0048] In this embodiment, if Figure 3 , Figure 7 , Figure 8As shown, the box body 1 includes an upper box body 11 and a lower box body 12, and the upper box body 11 and the lower box body 12 are connected in a flippable manner, and the spindle roller 2 and the inner lining plate 13 can be inspected and maintained by opening the upper box body 11. Optionally, an opening mechanism 16 is provided on the outer side of the end of the box body 1, and the opening mechanism 16 includes a telescopic cylinder, and the two ends of the telescopic cylinder are respectively hinged to the upper box body 11 and the lower box body 12, and the opening and closing control of the upper box body 11 and the lower box body 12 can be achieved by the extension and contraction of the telescopic cylinder. It is easy to understand that the opening mechanism 16 can also realize the opening control by driving the connecting shaft between the upper box body 11 and the lower box body 12 to rotate by a motor. The specific structure of the opening mechanism 16 is not limited here, and it is sufficient to realize the opening and closing control of the upper box body 11.

[0049] like Figure 7 , Figure 8 As shown, the feed port 111 is arranged on the upper box body 11, and the discharge port is arranged on the lower box body 12, which is convenient for the delivery of scrap metal and enables the processed scrap metal to be discharged from the discharge port by itself. Optionally, a feed hopper 14 is arranged on the upper box body 11, and the feed hopper 14 is connected to the upper box body 11 and communicated with the feed port 111. The feed hopper 14 is in a square funnel shape to increase the delivery area, and the scrap metal is guided by its inclined inner wall so that the scrap metal can fall smoothly into the feed port 111. A plurality of dust discharge holes 112 are arranged on the upper box body 11, and correspondingly, holes communicating with the dust discharge holes 112 are also arranged on the inner lining plate 13. A dust discharge cover 15 is arranged on the outer side of the upper box body 11, and the dust discharge cover 15 covers the plurality of dust discharge holes 112. Optionally, the dust discharge holes 112 are slender and narrow holes, and the dust discharge cover 15 is connected to a dust suction device to suck out the dust inside the box body 1.

[0050] Figure 3 As shown, a discharge hopper 17 is provided on the lower box 12, and the discharge hopper 17 is connected to the lower box 12 and communicated with the discharge port. The discharge hopper 17 includes a guide pipe, and the guide pipe can guide the discharge so that the processed scrap metal is discharged along the guide pipe. Optionally, an adjusting gate is provided in the discharge hopper 17 for adjusting the discharge speed. For example, the adjusting gate is rotatably provided in the guide pipe through a rotating shaft, and the state of the adjusting gate can be changed by rotating the rotating shaft. When the adjusting gate is perpendicular to the guide pipe, the guide pipe can be closed, so that the scrap metal cannot be discharged through the discharge port. In the process of rotating the adjusting gate to make it gradually parallel to the guide pipe, the flow area of ​​the guide pipe can be gradually increased, so that the discharge speed of the scrap metal is gradually accelerated. The setting of the adjusting gate allows the discharge speed of the scrap metal to be adjusted. When the discharge speed is slow, the retention time of the scrap metal in the processing channel can be extended, thereby extending the time of being kneaded and processed, so that the processing effect is better.

[0051] The lower box body 12 is also provided with a discharge port, such as Figure 8As shown, a discharge door 121 is provided at the discharge port, and the discharge door 121 is used to control the opening and closing of the discharge port. The discharge port can be used to discharge the scrap metal in the box body 1 in an emergency. For example, when there is too much scrap metal in the processing channel and the load of the motor is too large, the discharge port can be opened for emergency discharge. Optionally, a discharge control mechanism is provided on the lower box body 12, including a hydraulic cylinder, which is hinged to the discharge door 121 and the lower box body 12, and can control the opening and closing and the opening degree of the discharge door 121. Furthermore, a locking mechanism 122 is also provided on the lower box body 12, including a locking pin and an oil cylinder for controlling the locking pin. The locking pin can be slidably arranged on the edge of the discharge port, and the oil cylinder can control the sliding of the locking pin. When the discharge door 121 is closed, the locking pin slides to block the discharge door 121 so that the discharge door 121 is locked to withstand a greater extrusion force. In this embodiment, a discharge hopper 18 is provided on the lower box body 12 and is connected to the lower box body 12 for collecting the scrap metal discharged from the discharge port.

[0052] Optionally, an independent inner lining plate 13 is provided on the inner wall of the discharge door 121, which can be opened or closed along with the discharge door 121. Furthermore, the distance between the inner lining plate 13 on the discharge door 121 and the spindle roller 2 can be controlled by controlling the opening of the discharge door 121, so that the degree of kneading of the scrap metal by the portion where the discharge door 121 is located can be controlled. For example, when the discharge door 121 is opened at a relatively small angle, the scrap metal will not flow out of the discharge port due to the presence of the inner lining plate 13, but the gap between the inner lining plate 13 and the spindle roller 2 here is increased, so that more scrap metal can pass through, but the kneading effect will be reduced, which is suitable for rapid processing of scrap metal with a low degree of dirtiness.

[0053] In this embodiment, if Figure 1 As shown, the scrap metal finishing equipment also includes: a frame 3, a box body 1 is arranged on the frame 3, the box body 1 is placed horizontally on the frame 3, and the processing channel is also in a horizontal state, so that the scrap metal moves in the processing channel under the joint action of the main shaft roller 2 and the inner lining plate 13, rather than moving under the action of gravity, so that it can be effectively kneaded and processed throughout the entire movement.

[0054] The frame 3 is provided with a driving motor. In this embodiment, the driving motor includes a first motor 41 and a second motor 42. The first motor 41 and the second motor 42 are respectively arranged at the two ends of the box body 1. The first motor 41 is connected to the first end of the main shaft 21 by driving, and the second motor 42 is connected to the second end of the main shaft 21 by driving. The first motor 41 is a winding motor, and the second motor 42 is a squirrel cage motor. The two ends of the main shaft 21 extend out of the box body 1, and pulleys are arranged at both ends of the main shaft 21. The output shafts of the two motors are equipped with pulleys. The pulleys at both ends of the main shaft 21 are connected to the pulleys on the first motor 41 and the pulleys on the second motor 42 through belts. When working, the first motor 41 is started alone first, and when the main shaft roller 2 reaches the working speed, the second motor 42 is started to prevent the impact on the power grid. Optionally, the first motor 41 and / or the second motor 42 can drive the main shaft roller 2 to rotate in both directions, so that it is convenient to discharge.

[0055] The frame 3 is also provided with a pin pulling mechanism 5, which includes a telescopic rod, for example, a cylinder, and its telescopic end can be connected to the pin 23. The main shaft 21 rotates so that any pin 23 can be coaxial with the telescopic rod, and the telescopic rod is used to connect with the pin 23. The pin 23 is pulled out from the shaft hole, and the kneading hammer 24 and the kneading wheel 25 can be replaced.

[0056] The scrap metal finishing equipment workflow includes:

[0057] The first motor 41 (winding rotor motor) is started, and when the spindle roller 2 reaches the working speed, the second motor 42 (squirrel cage motor) is started;

[0058] The feed port 111 is used for feeding, and the smaller-sized scrap metals crushed by the crusher are put into the box body 1 through the feed port 111. Under the impact of the kneading hammer 24, the kneading and rolling of the kneading wheel 25 and the kneading structure on the inner lining plate 13, the scrap metals gradually move from the feed port 111 of the box body 1 to the discharge port. During this process, the floating rust, paint film and sludge are gradually peeled off from the metal and sucked away by the dust discharge hole 112 on the upper box body 11; after the scrap metals reach the discharge port, they are discharged from the box body 1 through the discharge hopper 17.

[0059] Optionally, according to the required processing effect, the opening of the gate can be adjusted by controlling the discharge hopper 17 to control the discharge speed of the equipment, thereby controlling the time for the scrap metal to pass through the processing channel. The slower the passing speed, the longer the scrap metal kneading treatment time, and the better the processing effect. Furthermore, the gap between the inner lining plate 13 on the discharge door 121 and the spindle roller 2 can be controlled by adjusting the opening of the discharge door 121 to appropriately control the processing effect.

[0060] When large-sized materials enter the machine body and the motor load suddenly increases, the discharge doors 121 are fully opened, and the materials are discharged from the machine body through the discharge doors 121 .

[0061] The present invention also provides a scrap metal processing system, including a scrap metal crusher and a scrap metal finishing device. Optionally, the scrap metal crusher is an existing device for crushing scrap metals. Any model or type of metal crusher can be selected, and its structure is not described in detail here. In the processing flow, the scrap metal finishing device is located at the rear side of the scrap metal crusher, and the scrap metal crushed by the scrap metal crusher is then placed in the scrap metal finishing device for processing. When processing larger scrap metal pieces, they are first placed in the scrap metal crusher for crushing to form smaller metal pieces, and then placed in the scrap metal finishing device for processing to remove paint film, sludge, rust, etc. on the surface of the scrap metal, thereby improving the quality of the scraps.

[0062] Optionally, the scrap metal processing system further comprises a compressor, and the scrap metal processed by the scrap metal finishing equipment is compressed and packaged by the compressor.

[0063] The scrap metal finishing equipment provided in the present application is used for finishing small-volume scrap metals after being crushed by a crusher, so that impurities such as paint film, floating rust, sludge, etc. on the surface of the scrap metals can be removed, thereby improving the quality of the scrap metal fragments. At the same time, some larger scrap metals can be further crushed into smaller metal pieces to increase the stacking density.
