Description

Technical Field

[0001] This utility model relates to the field of waste casting recycling technology, specifically to a crushing device for casting recycling. Background Technology

[0002] Casting waste refers to the waste generated during the casting process, mainly including metal powder, aluminum alloy slag, scrap copper, scrap iron, and other materials. With the acceleration of industrialization, the recycling and reuse of waste castings has become increasingly important. Traditional casting recycling methods are often inefficient, energy-intensive, and have a significant impact on the environment.

[0003] Currently, most casting recycling equipment on the market uses a single crushing method, such as hammer crushers or jaw crushers. When processing large castings, these machines do not crush them completely, resulting in castings of varying shapes and sizes after breakage, which increases the difficulty of subsequent processing. Utility Model Content

[0004] In view of this, the present invention provides a crushing device for casting recycling, which can not only pre-treat castings through a hydraulic mechanism to ensure that the material is properly compressed before entering the crushing stage and improve the efficiency of subsequent crushing, but also effectively crush large and hard castings through intermeshing crushing rollers. At the same time, smaller castings are screened out by a sorting component, while larger castings are crushed again by a crushing component located at the tail end of the screen plate, thereby improving crushing efficiency and crushing quality.

[0005] To solve the above-mentioned technical problems, this utility model provides a crushing device for casting recycling, including a hydraulic mechanism and a crushing mechanism. The hydraulic mechanism includes a support platform, on which a pressing component is fixedly mounted. A pushing component for material movement is connected to one side of the pressing component. The crushing mechanism includes an operation box disposed on one side of the support platform. A crushing component is disposed vertically inside the operation box, and a sorting component is disposed at an angle on the side of the lower crushing component.

[0006] The hydraulic mechanism can effectively pre-treat waste castings, ensuring that the material is properly compressed and moved before entering the crushing stage. Then, through the multiple crushing and sorting components set in the operation box of the crushing mechanism, the castings can be screened into small and large pieces. The larger pieces are then crushed again, improving the efficiency of subsequent waste casting processing.

[0007] The pressing assembly includes two guide rods symmetrically arranged on the support platform. A connecting plate is fixed to the top of the guide rods, and a hydraulic push rod is symmetrically arranged on the top of the connecting plate. A pressure plate is connected to the end of the telescopic shaft of the hydraulic push rod, and the pressure plate is slidably arranged on the guide rod through a guide ring.

[0008] The pressure plate is driven by hydraulic push rods to move up and down along the guide rods, applying pressure to the waste material placed on the material plate. The guide rods ensure the smooth movement of the pressure plate, and the symmetrically arranged hydraulic push rods ensure that the pressure plate applies uniform downward pressure to the casting, improving the pressing effect. Through effective casting pretreatment, the subsequent crushing work is simplified and the crushing effect is improved.

[0009] A material plate is slidably mounted on the bottom of the guide rod via a guide ring, and the material plate is connected to the load-bearing platform via four symmetrically arranged resetters.

[0010] The material tray allows for easy loading and unloading of materials, and the resetter ensures that the material tray automatically resets after pressing, improving the continuity and efficiency of the operation.

[0011] The pushing component includes a vertical plate disposed on one side of the pressing component. Several support plates are fixed on one side of the vertical plate. A pneumatic push rod for pushing material is mounted between the support plates. A pushing plate is connected to the end of the telescopic shaft of the pneumatic push rod. The pushing plate is slidably disposed on the surface of the material plate in the pressing component through the pneumatic push rod.

[0012] The material that has completed the pressing process is pushed to the crushing mechanism by a pusher plate driven by a pneumatic pusher. The use of pneumatic pushers provides stable and controllable thrust, ensuring that the material can be smoothly transferred from one processing stage to the next, improving the automation level of the entire process and reducing manual intervention.

[0013] The crushing assembly includes a rotating shaft symmetrically arranged in the control box, with crushing rollers sleeved on the shaft, and the symmetrical crushing rollers meshing with each other.

[0014] The castings are crushed by intermeshing crushing rollers, which can effectively crush large and hard castings, thereby improving crushing efficiency and quality.

[0015] A drive motor for driving the rotating shaft is fixed on the outer wall of the control box.

[0016] By powering the crushing components with a drive motor, the crushing rollers can operate continuously and efficiently, improving the stability and reliability of the crushing process.

[0017] The sorting component includes fixed plates symmetrically arranged on the side walls of the control box, each fixed plate is equipped with a shock-absorbing spring, and a sieve plate is connected between the shock-absorbing springs.

[0018] The castings are initially screened by the first crushing component through the screen plate, and the castings with poor crushing effect enter the crushing component located at the end of the screen plate for secondary crushing, which improves the recycling quality of the castings. At the same time, the shock-absorbing spring reduces the impact force on the equipment when the castings fall, so as to extend the service life of the equipment.

[0019] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0020] 1. The symmetrical and intermeshing crushing rollers effectively crush large and hard castings, ensuring that the castings are crushed evenly and thoroughly. The crushing components distributed above and below perform multiple crushing operations on the castings, improving crushing efficiency and quality, reducing the need for secondary processing due to incomplete crushing, and thus reducing overall processing time and energy consumption.

[0021] 2. The material is pre-treated by a hydraulic pusher to drive the pressure plate, and the treated material is automatically moved to the crushing mechanism by a pneumatic pusher to push the pusher plate. This improves the automation level of the equipment, reduces manual intervention, increases the continuity of operation and production efficiency, and reduces labor costs.

[0022] 3. The sieve plate in the sorting component enables the initial sorting of the crushed castings, which facilitates subsequent fine processing and resource recycling, thereby improving the quality and utilization rate of the recycled materials. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0029] like Figure 1-4 As shown: This embodiment provides a crushing device for casting recycling, including a hydraulic mechanism 1 and a crushing mechanism 2. The hydraulic mechanism 1 includes a support platform 11, on which a pressing component 12 is fixedly mounted. A pushing component 13 for material movement is connected to one side of the pressing component 12. The crushing mechanism 2 includes an operation box 21 disposed on one side of the support platform 11. A crushing component 22 is disposed vertically inside the operation box 21, and a sorting component 23 is disposed at an angle on one side of the lower crushing component 22.

[0030] The hydraulic mechanism 1 can effectively pre-treat the waste castings, ensuring that the material is properly compressed and moved before entering the crushing stage. Then, through the multiple crushing components 22 and sorting components 23 set in the operation box 21 of the crushing mechanism 2, the castings can be screened into small and large pieces. The larger pieces are then crushed again, improving the efficiency of subsequent waste casting processing.

[0031] The pressing assembly 12 includes two guide rods 121 symmetrically arranged on the support platform 11. A connecting plate 122 is fixedly provided on the top of the guide rods 121. A hydraulic push rod 123 is symmetrically provided on the top of the connecting plate 122. A pressure plate 124 is connected to the end of the telescopic shaft of the hydraulic push rod 123, and the pressure plate 124 is slidably arranged on the guide rods 121 through a guide ring.

[0032] The pressure plate 124 is driven to move up and down along the guide rod 121 by the hydraulic push rod 123, applying pressure to the waste material placed on the material plate 125. The guide rod 121 ensures the smooth movement of the pressure plate 124, and the symmetrically arranged hydraulic push rods 123 ensure the uniform downward pressure of the pressure plate 124 on the casting, improving the pressing effect. Through effective casting pretreatment, the subsequent crushing work is simplified and the crushing effect is improved.

[0033] A material plate 125 is slidably mounted on the bottom of the guide rod 121 via a guide ring. The material plate 125 is connected to the support platform 11 via four symmetrically arranged resetters 126.

[0034] A limit block is fixed on the top of the resetter 126 to prevent the material plate 125 from popping out when the reset is performed.

[0035] The material plate 125 allows for convenient loading and unloading of materials, while the resetter 126 ensures that the material plate 125 automatically resets after pressing, improving the continuity and efficiency of the operation.

[0036] The pushing component 13 includes a vertical plate 131 disposed on one side of the pressing component 12. A plurality of support plates 132 are fixed on one side of the vertical plate 131. A pneumatic push rod 133 for pushing material is mounted between the support plates 132. A push plate 134 is connected to the end of the telescopic shaft of the pneumatic push rod 133. The push plate 134 is slidably disposed on the surface of the material plate 125 in the pressing component 12 via the pneumatic push rod 133.

[0037] The support plate 132 provides support for the vertical plate, preventing the vertical plate 131 from tilting due to the reverse force generated by the pneumatic push rod 133 when pushing the casting.

[0038] The material that has completed the pressing process is pushed towards the crushing mechanism 2 by the pusher plate 134 driven by the pneumatic pusher 133. The use of the pneumatic pusher 133 provides a stable and controllable thrust, ensuring that the material can be smoothly transferred from one processing stage to the next processing stage, improving the automation level of the entire process and reducing manual intervention.

[0039] The crushing assembly 22 includes a rotating shaft 221 symmetrically arranged in the operation box 21, and crushing rollers 222 are sleeved on the rotating shaft 221, and the symmetrical crushing rollers 222 mesh with each other.

[0040] The castings are crushed by intermeshing crushing rollers 222, which can effectively crush large and hard castings, thereby improving crushing efficiency and quality.

[0041] A drive motor 223 for driving the rotating shaft 221 to rotate is fixed on the outer wall of the control box 21.

[0042] The crushing assembly 22 is powered by the drive motor 223, ensuring that the crushing roller 222 can operate continuously and efficiently, thereby improving the stability and reliability of the crushing process.

[0043] The sorting component 23 includes fixed plates 231 symmetrically arranged on the side walls of the operation box 21. Each fixed plate 231 is provided with a shock-absorbing spring 232, and a sieve plate 233 is connected between the shock-absorbing springs 232.

[0044] The castings crushed by the first crushing component 22 are initially screened by the screen plate 233, and the castings with poor crushing effect enter the crushing component 22 located at the tail end of the screen plate 233 for secondary crushing, thereby improving the recycling quality of the castings. At the same time, the shock-absorbing spring 232 reduces the impact force on the equipment when the castings fall, so as to extend the service life of the equipment.

[0045] The method of using this utility model is as follows: First, move the conveying equipment into the operating box 21 and position it directly below the crushing component 22 and the screen plate 233 at the tail end of the screen plate 233. Then, place the casting waste to be processed on the material plate 125 on the support platform 11, ensuring that the castings are evenly distributed. Next, activate the hydraulic push rod 123 to move the pressure plate 124 downward along the guide rod 121, pressing the castings and compressing them into a more compact state. After pressing, the material plate 125 will return to its original position by the return spring. Then, activate the pneumatic push rod 133 to push the push plate 134 to push the pre-processed waste. The casting is pushed from the material plate 125 into the control box 21. Then, the drive motor 223 located on the side wall of the control box 21 is started. The drive motor 223 drives the rotating shaft 221 to rotate, which drives the crushing roller 222 to rotate. The crushing roller 222 crushes the casting through the meshing and rotating crushing roller. The crushed casting falls onto the screen plate 233. Smaller pieces of the screen plate 233 are fed into the conveying equipment below through the holes on the screen plate 233, while larger casting fragments enter the crushing component 22 located at the tail end of the screen plate 233 for secondary crushing, so that they can be completely crushed.

[0046] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0047] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
