Description

Technical Field

[0001] This invention relates to the field of metal recycling and processing technology, specifically to a waste metal recycling and crushing device and method with anti-spraying features. Background Technology

[0002] In recent years, the scrap metal recycling industry has developed rapidly, with more and more companies investing in the recycling and processing of scrap metal. However, the crushing step is a crucial link in the scrap metal recycling process, directly affecting the efficiency and quality of subsequent processes such as sorting and smelting. As the country continues to place greater emphasis on safe production, relevant safety regulations and standards are becoming increasingly stringent. Companies must take effective safety measures during the scrap metal recycling and processing process to ensure the personal safety of operators and the normal operation of equipment.

[0003] In conjunction with the above, it should be noted that Chinese patent CN216605578U discloses an anti-splash metal crusher, which uses a sliding plate with a strong magnetic function to move above the metal crushing device to intercept the splashed debris generated by metal breakage in multiple ways. However, due to the combined interference of the impact force of metal breakage splash and impurities attached to the surface of the debris, there are significant defects in the interception of splashed metal debris.

[0004] Chinese Patent No. CN221907349U discloses a waste metal recycling, crushing, and sorting device with anti-splashing mechanism. The device uses a rotating protective door to form a controllable closed anti-splashing component on the top of the metal crushing device. Although this effectively protects against the splashing hazards of metal fragments during processing, the semi-circular shape of the protective door body significantly limits the continuous feeding of waste metal, resulting in low efficiency in continuous processing of waste metal.

[0005] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a waste metal recycling and crushing device and method with anti-spraying features to solve the problems mentioned above.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a waste metal recycling and crushing device with anti-spraying features, comprising a crusher body, with external support frames symmetrically arranged on the top outer walls of both sides of the crusher body, an anti-spraying cover located above the crusher body on the top of the external support frames, a feed adjustment guide plate connected to the top of one side of the crusher body, and a lower rotary cylinder located above the external support frames and connected to the feed adjustment guide plate on the top outer wall of one side of the crusher body;

[0008] An adjustable cover plate is hinged to the top of one side of the anti-spray cover, and a pressing top frame is provided at the center of the top of the anti-spray cover. An arc-shaped pressing plate facing the inside of the crusher body is provided at the bottom of the pressing top frame.

[0009] Furthermore, the crusher body has a trumpet-shaped feed rack at the top, the feed adjustment guide plate is hinged to the top of one side of the feed rack, multiple sets of crushing rollers are arranged in the center inside the crusher body, the bottom of the crusher body has a discharge guide groove located below the multiple sets of crushing rollers, and a servo motor that is drivenly connected to the multiple sets of crushing rollers is arranged on the end face of the crusher body.

[0010] Furthermore, the inner walls at both ends of the outer support frame are provided with sleeves close to the crusher body, and a lifting rod is installed through the sleeve. The bottom of the lifting rod is sleeved with the bottom end face of the crusher body, and a lifting cylinder connected to the anti-spray cover is embedded at the top of the lifting rod.

[0011] Furthermore, an inner rotating roller is sleeved inside the outer support frame. The inner rotating roller is equipped with multiple sets of non-magnetic plates and strong magnets, which are arranged in a staggered ring on the outer peripheral wall of the inner rotating roller. A thin plate extending to the top inner wall of the crusher body is provided on the inner wall of the outer support frame. The thin plate is made of either permalloy or ferrite material. One end of the inner rotating roller is provided with a driven wheel that penetrates to the end face of the outer support frame. A synchronous belt that drives and connects to the output end of the servo motor is sleeved on the surface of the driven wheel. The synchronous belt is adapted and installed according to actual needs and is replaced according to its service life.

[0012] Furthermore, the top of both sides of the anti-spray cover is provided with a sleeve frame, the side of the anti-spray cover is provided with an upper rotary cylinder that is connected to the adjusting cover plate, and the top of the anti-spray cover is provided with a winding motor near the pressing top frame.

[0013] Furthermore, a telescopic curtain is installed inside the adjusting cover plate, and a counterweight is provided at one end of the telescopic curtain near the adjusting pressure plate. The other end of the telescopic curtain passes through the anti-spray cover and is connected to the winding motor. A winding chamber is provided outside the winding motor.

[0014] Furthermore, the top two ends of the pressing frame are provided with through holes that penetrate the anti-spray cover. A pressing cylinder is installed inside the through hole. The bottom of the pressing cylinder is sleeved with an arc-shaped pressure plate. Multiple sets of arc-shaped grooves are recessed on both sides of the bottom of the arc-shaped pressure plate. An extension arc strip is slidably sleeved inside the arc-shaped groove. A propulsion cylinder that is drivenly connected to the extension arc strip is installed inside the arc-shaped groove.

[0015] This invention also proposes a working method for a scrap metal recycling and crushing device with anti-flying features, comprising the following steps:

[0016] Continuous feeding: The feeding adjustment guide plate and the adjustment cover plate open in opposite directions in conjunction, forming a continuous feeding channel for scrap metal on one side between the feeding rack and the anti-spray cover;

[0017] Adaptive anti-flying cover: The anti-flying cover slides axially to cover the top of the feed rack, which can not only form a controllable chamber for the continuous breaking of irregular scrap metal, but also form a range of coverage and interception protection above the crusher body by using telescopic curtains in combination with the anti-flying cover.

[0018] Drop-pressure assisted crushing: The pressing top frame and the anti-flying cover move synchronously close to the top of the crusher body, which makes it easy to adjust the downward pressure and expansion during the crushing of irregular scrap metal, and apply downward pressure to the irregular scrap metal to improve the crushing efficiency.

[0019] Rotary magnetic traction: The inner rotating roller rotates synchronously with the crushing roller. With the assistance of the thin plate, it performs local magnetic traction on the waste metal that is normally crushed inside the crusher body, reducing the outward ejection of metal debris near the top area of ​​the crusher body.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention constructs a continuous feeding channel by linking and opening the feed adjustment guide plate and the adjustment cover plate in opposite directions. The distance between the two can be adjusted in advance and in real time according to the shape of the scrap metal. With the upper and lower rotary cylinders driving the feed adjustment guide plate and the adjustment cover plate to move flexibly, it can adapt to the feeding needs of scrap metal of different shapes and sizes, ensure the smoothness and continuity of feeding, and improve the compatibility of the device with various scrap metals and the feeding efficiency.

[0022] 2. This invention uses an anti-spray cover that slides axially down to cover the feed rack, forming a controllable chamber. Combined with a telescopic curtain, it provides a wide-range coverage and interception protection, reducing the probability of metal debris flying out. At the same time, the telescopic curtain covers the opening, allowing flying debris to fall onto the scrap metal and flow back into the crusher body. This ensures operator safety, avoids material loss, and is beneficial to environmental protection and resource recycling. The inner rotating roller rotates synchronously with the crushing roller. Using the alternating action of a strong magnet and a non-magnetic plate, it magnetically attracts and releases metal debris inside the crusher body, causing the metal debris to approach the inner walls on both sides and fall onto the crushing roller for further crushing. This effectively reduces the outward flight of metal debris and accelerates the overall crushing process of scrap metal, improving crushing effect and quality.

[0023] 3. This invention utilizes a pressure top frame that can autonomously adjust its downward and outward movements during scrap metal crushing, applying pushing and compressing pressure to irregular scrap metal and improving crushing efficiency. Furthermore, by acquiring crushed weight and feed load values ​​through chip and metal weighing sensors, and interacting with a cloud database for analysis, the invention can automatically determine crushing efficiency based on the difference between the feed and output volumes and take corresponding measures. For example, when efficiency is abnormal, it can activate the downward and forward cylinders to accelerate crushing; when efficiency is normal, it can generate a prompt signal, achieving intelligent crushing control, ensuring stable and efficient operation of the device, and reducing manual intervention.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figure 1 - Figure 8 As shown, this embodiment is a waste metal recycling and crushing device with anti-spraying features, including a crusher body 1, with external support frames 2 symmetrically arranged on the top outer walls of both sides of the crusher body 1, an anti-spraying cover 3 located above the crusher body 1 on the top of the external support frames 2, a feed adjustment guide plate 103 hinged to the top of one side of the crusher body 1, and a lower rotary cylinder 5 located above the external support frames 2 and connected to the feed adjustment guide plate 103 on the top outer wall of one side of the crusher body 1;

[0036] Irregular scrap metal is disassembled in advance, and scrap metal with similar shapes is transported and sorted. The distance between the anti-flying cover 3 and the crusher body 1 is adjusted in advance according to the shape of the scrap metal, so that the distance between the feed adjustment guide plate 103 and the adjustment cover plate 301 is gradually reduced. The feed adjustment guide plate 103 and the adjustment cover plate 301 are further adjusted according to the shape of the scrap metal on the conveyor frame.

[0037] The crusher body 1 is equipped with a trumpet-shaped feed rack 101 at the top. The feed adjustment guide plate 103 is hinged to the top of one side of the feed rack 101. When the lower rotary cylinder 5 is started, it drives the feed adjustment guide plate 103 to rotate and flip outward along the feed rack 101 through related accessories, so that the opening in the middle of one side of the feed rack 101 is further opened after adjustment, so that scrap metal can enter.

[0038] Multiple sets of crushing rollers 102 are arranged in the center of the crusher body 1. A discharge guide chute 104 is arranged at the bottom of the crusher body 1 below the multiple sets of crushing rollers 102. A servo motor that is connected to the multiple sets of crushing rollers 102 is arranged on the end face of the crusher body 1.

[0039] The inner walls at both ends of the outer support frame 2 are provided with a sleeve 201 close to the crusher body 1. A lifting rod 202 is installed through the sleeve 201. The bottom of the lifting rod 202 is sleeved with the bottom end face of the crusher body 1, and the top of the lifting rod 202 is embedded with a lifting cylinder connected to the anti-spray cover 3.

[0040] An inner rotating roller 204 is sleeved inside the outer support frame 2. The inner rotating roller 204 has multiple sets of non-magnetic plates and strong magnets on its roller body. The non-magnetic plates and strong magnets are arranged in a staggered ring on the outer peripheral wall of the inner rotating roller 204. A thin plate 205 extending to the top inner wall of the crusher body 1 is provided on the inner wall of the outer support frame 2. The thin plate 205 is made of either permalloy or ferrite material. One end of the inner rotating roller 204 is provided with a driven wheel 203 that penetrates to the end face of the outer support frame 2. A synchronous belt that is connected to the output end of the servo motor is sleeved on the surface of the driven wheel 203. The synchronous belt is specifically adapted and installed according to actual needs and replaced according to its service life.

[0041] During the crushing of scrap metal by the crusher body, the driven wheel 203 is connected to the output of the servo motor via a synchronous belt. The output of the servo motor can be equipped with a reducer connected to the synchronous belt, thereby reducing the rotation speed of the inner roller 204. The driven wheel 203 drives the inner roller 204 to rotate, and the inner roller 204 drives the non-magnetic plate and the strong magnet to rotate. When the strong magnet approaches the thin plate 205, the magnetic force of the strong magnet itself is increased due to the influence of the material of the thin plate 205, and extends towards the top area inside the crusher body, causing the metal scraps near this area to be briefly magnetically attracted, thereby approaching the inner walls on both sides of the crusher body 1. When the non-magnetic plate approaches the thin plate 205, the magnetic force intensity is reduced, causing the metal scraps that were previously magnetically attracted to fall onto the crushing roller 102. With the continuous rotation of the crushing roller 102, it drives further crushing, thereby accelerating the crushing efficiency of scrap metal.

[0042] Example 2: This example is a waste metal recycling and crushing device with anti-spraying features. It includes an adjustable cover plate 301 hinged to the top of one side of the anti-spraying cover 3, and a pressing frame 4 is provided at the center of the top of the anti-spraying cover 3. The bottom of the pressing frame 4 is provided with an arc-shaped pressing plate 402 facing the inside of the crusher body 1. The upper rotary cylinder 304 is connected to the adjustable cover plate 301 through fasteners. The upper rotary cylinder 304 is started and drives the adjustable cover plate 301 to hinge downwards and inwards or upwards and outwards along one side of the anti-spraying cover 3.

[0043] When the adjusting cover plate 301 flips inward downward, the adjusting cover plate 301 gradually faces vertically downward, forming a temporary connection mechanism above the feed adjusting guide plate 103, which is used in conjunction with the feed adjusting guide plate 103 to reduce the flying debris caused by metal damage inside the crusher body 1.

[0044] When the adjusting cover plate 301 flips upwards and outwards, it is used to cooperate with the feed adjusting guide plate 103 to increase the opening size on the basis of the original inlet, so as to help large and irregular scrap metal enter the crusher body 1.

[0045] The anti-spray cover 3 has a sleeve 302 on both sides of the top. When the anti-spray cover 3 slides down and approaches the feed rack 101, the cavity between the anti-spray cover 3 and the feed rack 101 is semi-sealed, reducing the connection gap between the two and the external environment, thereby reducing the probability of metal debris flying. The side of the anti-spray cover 3 is equipped with an upper rotary cylinder 304 that is connected to the adjusting cover plate 301. The top of the anti-spray cover 3 is equipped with a winding motor 305 near the pressing top frame 4.

[0046] The winding motor 305 starts and drives the telescopic curtain 303 to unwind through related accessories. These related accessories include a winding roller. The output end of the winding motor 305 is equipped with a winding roller that is sleeved inside the winding chamber. The winding roller rotates, causing the telescopic curtain 303 wrapped on its surface to move along the channel between the anti-spray cover 3 and the adjusting cover plate 301.

[0047] Under the action of the counterweight, the telescopic curtain 303 extends outward and then vertically downward until it approaches the area of ​​the feed adjustment guide plate 103, blocking the opening between the anti-flying cover 3 and the feed adjustment guide plate 103. This helps to intercept the flying metal debris inside the crusher body 1 and drop it onto the continuously entering scrap metal and the surface of the feed adjustment guide plate 103. With the traction and pushing of the subsequent entering scrap metal, it flows back into the crusher body 1.

[0048] A telescopic curtain 303 is installed inside the adjusting cover plate 301. A counterweight is provided at one end of the telescopic curtain 303 near the adjusting pressure plate 301. The other end of the telescopic curtain 303 passes through the anti-flying cover 3 and is connected to the winding motor 305. A winding chamber is provided outside the winding motor 305.

[0049] Example 3: This example is a waste metal recycling and crushing device with anti-spraying features. It includes a pressing top frame 4 with through holes at both ends of the top, penetrating the anti-spraying cover 3. A pressing cylinder 401 is installed inside the through holes. The bottom of the pressing cylinder 401 is sleeved with an arc-shaped pressing plate 402. Multiple sets of arc-shaped grooves are recessed on both sides of the bottom of the arc-shaped pressing plate 402. An extension arc strip 403 is slidably sleeved inside the arc-shaped groove. A propulsion cylinder that is drivenly connected to the extension arc strip 403 is installed inside the arc-shaped groove.

[0050] When the anti-flying cover 3 contacts the top of the feed rack 101, and when the adjusting cover plate 301 and the feed adjusting guide plate 103 work together to form a continuous feed opening for scrap metal, the crusher body 1 continuously crushes the continuously entering scrap metal, and the servo motor drives the crushing roller 102 to rotate through the shaft and other related accessories.

[0051] During the crushing of scrap metal by the crushing roller 102, a scrap weighing sensor is installed inside the discharge guide chute 104 to count the total weight of the scrap generated by the continuous crushing of scrap metal by the crusher body 1, thereby obtaining the crushing weight value PS. A metal weighing sensor is installed in the area where the feed rack 101 is connected to the external conveying equipment to weigh the scrap metal continuously entering the crusher body 1, thereby obtaining the feed load value ZZ. The crushing weight value PS and the feed load value ZZ are sent to the main controller of the crushing equipment, and the main controller is connected to the cloud database.

[0052] After obtaining the crushing weight value PS and the feed load value ZZ, the cloud database performs analysis every 2 minutes according to a preset analysis cutoff time. It marks and compares the individually obtained crushing weight value PS and feed load value ZZ within each 2-minute interval, converting them using the formula PS - ZZ = R, where R represents the difference between the crushing feed and output within the cutoff time. It also retrieves a preset difference range threshold Ry from the cloud database and compares it with the actual crushing feed and output difference R.

[0053] If the difference between the crushing feed and output R is less than the minimum value of the preset difference range threshold Ry, it is determined that the crushing efficiency of the crushing device is abnormal within the current interception time, and an alarm signal is generated. The cloud database sends the generated alarm signal to the main controller, and the main controller immediately starts the pressing cylinder 401. The pressing starts and drives the arc-shaped pressure plate 402 to slide down. The arc-shaped pressure plate 402 continues to slide down and contacts the scrap metal retained inside the crusher body 1. The pushing cylinder simultaneously drives the extending arc strip 403 to expand to both sides along the arc groove, specifically increasing the contact area of ​​the scrap metal retained inside the crusher body 1. With the continuous pushing of the pressing cylinder 401, the scrap metal accelerates to contact the crushing roller 102. With the continuous rotation of the crushing roller 102, the scrap metal under pressure is quickly crushed, reducing the retention of scrap metal and maintaining continuous feeding and continuous discharge of scrap metal.

[0054] If the difference between the crushing input and output R is greater than the minimum value of the preset difference range threshold Ry, then it is determined that the crushing efficiency of the crushing device is within a controllable range during the current interception time.

[0055] In summary, based on the range where the difference between the crushing feed and output values ​​R falls within the preset difference range threshold Ry, a corresponding prompt signal is generated, as shown below:

[0056] When the difference between the crushing feed and output values ​​R is close to the average value of the preset difference range threshold Ry, it indicates that the crushing device is operating well and generates a good signal. Based on the good signal, the device generates text in the style of "Crushing well / Continuous operation" and displays it on the display screen of the main controller.

[0057] When the difference between the crushing feed and discharge rates R approaches the maximum value of the preset difference range threshold Ry, it indicates that the crushing device is operating in excellent condition, generating an excellent signal. Based on the excellent signal, the device generates text in the style of "Excellent crushing / Continuous operation / Increased feed rate" and displays it on the display screen of the main controller.

[0058] If the difference between the crushing feed and output R is greater than the maximum value of the preset difference range threshold Ry, it indicates an abnormal continuous feeding and generates a feeding abnormality signal. Based on the feeding abnormality signal, the system generates text in the style of "Crushing is good / Material shortage / Feeding scheduling / Stop standby" and displays it on the display screen of the main controller to remind the operator of the crushing device.

[0059] As can be seen from Embodiments 1, 2, and 3, the present invention uses the linkage between the feed adjustment guide plate 103 and the adjustment cover plate 301 to adjust the distance in real time according to the metal shape, and the rotary cylinder to ensure smooth and continuous feeding, thereby improving compatibility and efficiency. The anti-spray cover 3 slides down and combines with the telescopic curtain 303 to form protection, reducing the flying of debris. The inner rotating roller 204 rotates with the crushing roller 102 to magnetically attract and pull the debris, accelerating crushing and preventing external ejection.

[0060] The pressing top frame 4 can adjust its downward pressure independently. Combined with sensors and a cloud database, it can intelligently judge efficiency based on the difference between the crushing feed and output. When there is an abnormality, it will start the relevant cylinder to accelerate crushing. When it is normal, it will generate a prompt signal to achieve intelligent and stable operation and reduce manual intervention.

[0061] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
