[0002] There are many types of equipment for the treatment and recycling of foundry waste sand, covering multiple processing stages such as crushing, screening, regeneration, and dust removal. The circumferential crusher is a type of equipment used to regenerate resin sand used in foundry production, aiming to achieve the recycling of old sand, reduce production costs, and reduce environmental pollution.

[0003] Existing circular crushers use a vibrating motor to drive the old sand in the crushing chamber to vibrate, causing the old sand blocks to rub against the wear-resistant points on the inner wall of the crushing chamber and be crushed into smaller sand particles. The sand particles fall into the storage chamber through the screen and are discharged from the outlet. However, its crushing efficiency is low, and the screen is usually fixedly installed on the inner wall of the crushing chamber, which is not easy to disassemble and thus not easy to replace. Utility Model Content

[0004] The purpose of this utility model is to provide a foundry waste sand treatment and recycling equipment, which solves the problems of low crushing efficiency of existing circumferential crushers and the fact that the screen is usually fixed on the inner wall of the crushing chamber, making it inconvenient to disassemble and replace the screen.

[0005] To achieve the above objectives, a foundry waste sand treatment and recycling device is provided, comprising: a base, a vibration motor fixedly connected inside the base, a connecting rod fixedly connected to the output end of the vibration motor via a coupling, the top end of the connecting rod fixedly connected to the bottom of the storage chamber, a vibration sleeve fixedly connected to the top of the base, a vibration spring fixedly connected inside the vibration sleeve, a vibration rod fixedly connected to the top end of the vibration spring, and the top end of the vibration rod fixedly connected to the bottom of the storage chamber, facilitating the crushing of sand blocks;

[0006] A screen is movably connected to the top of the storage chamber, and a crushing chamber is movably connected to the top of the screen. A drive motor is fixedly connected to the top of the crushing chamber. The output end of the drive motor is fixedly connected to a rotating shaft via a coupling. A crushing rod is fixedly connected to the outer wall of the rotating shaft, thereby improving the crushing rate of the sand blocks.

[0007] According to the aforementioned foundry waste sand treatment and regeneration equipment, the shape and size of the vibrating rod are matched with the shape and size of the vibrating sleeve. The vibrating rod is slidably connected to the inner wall of the vibrating sleeve under the action of the vibrating spring, which facilitates the movement of the vibrating rod and improves the vibration amplitude of the crushing chamber.

[0008] According to the foundry waste sand treatment and regeneration equipment, the number of the vibrating sleeve, vibrating spring and vibrating rod is ten, and the ten vibrating sleeve, vibrating spring and vibrating rod are fixedly installed on the top of the base in a circumferential array to facilitate the vibration of the crushing chamber.

[0009] According to the foundry waste sand treatment and recycling equipment, the top of the crushing chamber is provided with a feed inlet, and the side of the storage chamber is provided with a discharge outlet, which facilitates the feeding and discharging of waste sand.

[0010] According to the aforementioned foundry waste sand treatment and regeneration equipment, the bottom wall of the storage chamber is inclined to facilitate the discharge of sand particles.

[0011] According to the foundry waste sand treatment and regeneration equipment, the inner wall of the crushing chamber is provided with wear-resistant points, and the wear-resistant points are fixedly installed on the inner wall of the crushing chamber in a circumferential array to facilitate the crushing of sand blocks.

[0012] According to the foundry waste sand treatment and regeneration equipment, the screen has internal sieve holes to facilitate the screening of sand particles.

[0013] According to the foundry waste sand treatment and regeneration equipment, flanges are provided on the top of the storage chamber, the bottom of the crushing chamber, and the screen, and flange holes are provided on the top of the flanges to facilitate the installation and disassembly of the screen and the crushing chamber.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. This circular crusher uses a vibrating motor to drive the vibration of the old sand in the crushing chamber, and a drive motor to drive the rotation of the shaft and crushing rod. During the rotation, the crushing rod breaks up large sand blocks and drives the movement of sand particles, so that smaller sand particles can quickly pass through the screen. At the same time, the stirring rod drives the sand particles in the crushing chamber to make circular motion, which accelerates the friction rate between the sand particles and the wear-resistant points, thereby improving the crushing rate of waste sand.

[0016] 2. This circumferential crusher features flanges at the top of the storage chamber, the screen, and the bottom of the crushing chamber. The crushing chamber and screen are installed on top of the storage chamber using bolts and nuts, facilitating the installation and disassembly of the crushing chamber and screen, and thus making screen replacement easier, thereby improving the practicality of the circumferential crusher.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4 This utility model embodiment discloses a foundry waste sand treatment and recycling device, which includes: a base 1, a vibration motor 2 fixedly connected inside the base 1, a connecting rod 3 fixedly connected to the output end of the vibration motor 2 through a coupling, the top end of the connecting rod 3 fixedly connected to the bottom of the storage chamber 4, a vibration sleeve 5 fixedly connected to the top of the base 1, a vibration spring 6 fixedly connected inside the vibration sleeve 5, a vibration rod 7 fixedly connected to the top end of the vibration spring 6, and the top end of the vibration rod 7 fixedly connected to the bottom of the storage chamber 4. The vibration motor 2 and the vibration spring 6 drive the sand blocks in the crushing chamber 11 to vibrate, causing the sand blocks to move up and down and rub against the wear-resistant points 18, thereby crushing the sand blocks into smaller sand particles.

[0027] A screen 10 is movably connected to the top of the storage chamber 4, and a crushing chamber 11 is movably connected to the top of the screen 10. A drive motor 13 is fixedly connected to the top of the crushing chamber 11. A rotating shaft 14 is fixedly connected to the output end of the drive motor 13 through a coupling. A crushing rod 15 is fixedly connected to the outer wall of the rotating shaft 14. The drive motor 13 drives the crushing rod 15 to rotate, which in turn drives the sand blocks in the crushing chamber 11 to move in a circular motion. This not only crushes the sand blocks but also speeds up the rate at which the sand particles pass through the screen 10.

[0028] The shape and size of the vibrating rod 7 match those of the vibrating sleeve 5. The vibrating rod 7 slides against the inner wall of the vibrating sleeve 5 under the action of the vibrating spring 6. The vibrating spring 6 vibrates up and down under the action of the vibrating motor 2, thereby driving the movement of the vibrating rod 7 and increasing the vibration amplitude of the crushing chamber 11. There are ten vibrating sleeves 5, vibrating springs 6, and vibrating rods 7, arranged in a circular array and fixedly installed on the top of the base 1. The top of the crushing chamber 11 has a feed inlet 12, and one side of the storage chamber 4 has a discharge outlet 8 for easy feeding and discharging of waste sand. The bottom wall of the storage chamber 4 is inclined, allowing sand particles to slide along the bottom wall to the discharge outlet 8 for easy discharge. The inner wall of chamber 11 is provided with wear-resistant points 18, which are fixedly installed in a circumferential array on the inner wall of crushing chamber 11. Under the action of vibrating motor 2 and drive motor 13, the sand block moves up and down and in a circular motion and rubs against the wear-resistant points 18, so that the sand block is crushed into smaller sand particles. The screen 10 has screen holes 16 inside. Smaller sand particles enter the storage chamber 4 through the screen holes 16, while larger sand particles remain on the screen 10 for crushing. Flanges 9 are provided on the top of storage chamber 4, the bottom of crushing chamber 11 and screen 10. Flange holes 17 are provided on the top of the flanges 9. Storage chamber 4, screen 10 and crushing chamber 11 are connected by flange holes 17, fixing bolts and nuts. Installation and disassembly are relatively simple, which facilitates the cleaning and replacement of screen 10.

[0029] Working principle: Waste sand is poured into the crushing chamber 11 through the feed inlet 12 at the top of the crushing chamber 11. The vibration motor 2 and drive motor 13 are started. The vibration motor 2 transmits the vibration force to the vibration spring 6 through the connecting rod 3, which drives the vibration spring 6 to vibrate, thereby driving the vibration of the waste sand in the crushing chamber 11. The waste sand blocks move up and down and rub against the wear-resistant points 18 on the inner wall of the crushing chamber 11, thereby crushing them into smaller sand particles. The sand particles pass through the screen 10 into the storage chamber 4 and are discharged through the discharge port 8. At the same time, the drive motor 13 drives the rotating shaft 14 and the crushing rod 15 to move, thereby accelerating the crushing rate of the sand blocks. When the screen 10 needs to be replaced, the fixing bolts on the flange 9 are removed, and the crushing chamber 11 and screen 10 can be removed for easy cleaning and replacement of the screen 10.
