Description

Technical Field

[0001] The utility model relates to the technical field of waste material recovery, in particular to a device for recovering waste sand from metal castings. Background Art

[0002] During the casting process of metal castings, various qualified sands are needed to create molds. After the use of these sand molds, the sand will increase the waste residue of the casting raw materials, which cannot be reused and forms waste sand. The metal casting waste sand recovery device mainly involves the field of environmental protection technology, aiming to effectively recover and reuse the waste sand generated during the casting process. This device is suitable for the recovery of waste sand generated during the casting process of various metal castings, such as those in the foundry industry such as automotive parts and mechanical parts. By recycling and reusing waste sand, production costs can be reduced, resource utilization efficiency can be improved, and the impact on the environment can be reduced.

[0003] The position of the filter screen of the existing waste sand recovery device is fixed when recovering waste sand, and the filter screen cannot be vibrated, and thus the waste sand cannot be screened. The waste sand may clog the filter screen, reducing the practicality of the waste sand recovery device when in use.

[0004] An existing patent (publication number: CN220532897U) discloses a foundry waste sand recovery device. The device comprises a fixed housing with a top cover secured to the top. A feed chute is located within the housing. A drive motor is mounted on the exterior of the housing, and a grinding roller is fixedly connected to the motor's output. The grinding roller crushes and recovers the waste sand. A servo motor drives a reel in forward and reverse rotation, which in turn drives a screen plate in a circular motion within the housing via a steel cable. A spring vibrates the screen plate, preventing sand from clogging it and improving sand recovery quality.

[0005] In response to the above problems, although the solution provided by the existing patent drives the winding rod to rotate forward and reverse through a servo motor, thereby causing the screen plate to vibrate, it can only crush the waste sand once when recycling the waste sand, resulting in incomplete crushing of the waste sand, which is not conducive to subsequent recycling and use. Summary of the Invention

[0006] The purpose of the utility model is to provide a waste sand recovery device for metal castings, which can perform an initial crushing of the waste sand material, and then grind and crush it again between the grinding roller and the auxiliary plate, thereby improving the crushing effect of the waste sand material. By twisting the adjusting screw, the distance between the auxiliary plate and the grinding roller can be adjusted, and the diameter of the waste sand grinding particles can be conveniently adjusted to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a metal casting waste sand recovery device, comprising a device housing, a lower surface of which is fixed with support legs, and an interior of the device housing is equipped with a crushing mechanism for recovering waste sand;

[0025] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4 A metal casting waste sand recovery device includes a device housing 1, a support leg 2 is fixed to the lower surface of the device housing 1, and a crushing mechanism for recovering waste sand is installed inside the device housing 1;

[0028] The crushing mechanism includes a fixed plate 3, which is fixed to the inside of the device housing 1. A dual-axis motor 31 is fixed to the upper surface of the fixed plate 3 by bolts. One output shaft of the dual-axis motor 31 is fixed to a mounting tube 32. Two fixed rods 33 are fixed to the outer surface of the mounting tube 32. The ends of the two fixed rods 33 are sleeved with fixed bearings 34. The outer surface of the fixed bearings 34 is fixed with a crushing roller 35. The other output shaft of the dual-axis motor 31 passes through the fixed plate 3 and is fixed with a grinding roller 36. Two adjusting plates 37 are provided on the outside of the grinding roller 36. The inner surfaces of the two adjusting plates 37 are fixed with auxiliary plates 38 that cooperate with the grinding roller 36. The outer walls of the two adjusting plates 37 are rotatably connected to adjusting screws 39 through bearings. The adjusting screws 39 are threadedly connected to the device housing 1. A number of through holes 310 are evenly spaced inside the fixed plate 3.

[0029] By adopting the above technical solution, before using the metal casting to cast the waste sand recovery device, the device shell 1 is first placed in a suitable position. The support legs 2 provided can ensure the stability of the device. The dual-axis motor 31 on the fixed plate 3 is started, driving the mounting tube 32 to rotate, thereby driving the fixed rod 33 to move. Through the provided fixed bearing 34, when the fixed rod 33 moves, the crushing roller 35 can move in a circular motion on the upper surface of the fixed plate 3, thereby crushing the waste sand material. The crushed waste sand material can fall to the bottom through the through hole 310 opened on the fixed plate 3. When the dual-axis motor 31 is running, it will synchronously drive the grinding roller 36 to rotate, so that the waste sand material is ground and crushed again when passing between the grinding roller 36 and the auxiliary plate 38, thereby improving the crushing effect of the waste sand material. By screwing the adjusting screw 39, the adjusting plate 37 can be driven to move horizontally, thereby adjusting the distance between the auxiliary plate 38 and the grinding roller 36, thereby facilitating the adjustment of the diameter of the waste sand grinding particles.

[0030] Specifically, such as Figure 1-Figure 2 As shown, a first screen 4 is installed at the lower part of the interior of the device housing 1, and a second screen 5 fixed to the device housing 1 is provided below the first screen 4. A discharge port 6 matching the first screen 4 and the second screen 5 is provided on the outer surface of the device housing 1, and a protective cover 7 is installed on the upper surface of the device housing 1, and a feed port 8 is provided at the upper end of the protective cover 7.

[0031] By adopting the above technical solution, waste sand material is put into the device through the feed port 8 on the protective cover 7. The protective cover 7 can play a protective role, thereby avoiding splashing when the waste sand is crushed. The crushed waste sand is then screened by the first screen 4 and the second screen 5, and then discharged to the outside through the corresponding discharge port 6 for collection.

[0032] Working principle: Place the device shell 1 in a suitable position, and put waste sand materials into the device through the feed port 8 on the protective cover 7. The protective cover 7 provided can play a protective role. The dual-axis motor 31 on the fixed plate 3 is started, driving the mounting tube 32 to rotate, and then driving the fixed rod 33 to move. Through the provided fixed bearing 34, when the fixed rod 33 moves, the crushing roller 35 can move in a circular motion on the upper surface of the fixed plate 3, which can crush the waste sand materials. The crushed waste sand materials can pass through the through hole 310 opened on the fixed plate 3. 310 falls to the bottom, and when the dual-axis motor 31 is running, it will synchronously drive the grinding roller 36 to rotate, so that the waste sand material is ground and crushed again when passing between the grinding roller 36 and the auxiliary plate 38, thereby improving the crushing effect of the waste sand material, and by twisting the adjusting screw 39, the adjusting plate 37 can be driven to move horizontally, thereby adjusting the distance between the auxiliary plate 38 and the grinding roller 36, so as to facilitate the adjustment of the diameter of the waste sand grinding particles. The crushed waste sand is then screened by the first screen 4 and the second screen 5, and discharged to the outside through the corresponding discharge port 6 for collection.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
