[0030] like Figures 1 to 7 The sand processing device shown includes: a sand storage mechanism 10, a processing mechanism 20, and a control center 30. The control center 30 is electrically connected to the sand storage mechanism 10 and the processing mechanism 20 and is used to control the start and stop of the operation of the sand storage mechanism 10 and the processing mechanism 20. The sand storage mechanism 10 is located at the output end of the processing mechanism 20 and includes multiple sand storage tanks 11. A communication port 12 is provided in adjacent sand storage tanks 11.

[0031] The processing unit 20 includes a vibrating feeder 21, a crusher 22, and a screening machine 23 arranged sequentially along the feeding direction. The vibrating feeder 21 is connected to the feed inlet of the crusher 22 and is used to convey sand blocks to be processed into the crusher 22. The feed inlet of the screening machine 23 is connected to the discharge outlet of the crusher 22 and is used to receive and classify the sand particles processed by the crusher 22. The screening machine 23 is provided with a circulation port, which is connected to the feed inlet of the crusher 22.

[0032] This invention, through the combination of a vibrating feeder 21, a crusher 22, and a screening machine 23, can achieve fine crushing of sand particles, making the sand particle size more uniform and meeting molding requirements; and through the control center 30, it can achieve automated comprehensive control, so that the sand particles after sand processing can automatically enter the sand storage mechanism 10, reducing manual operation and thus improving the efficiency of the sand processing process.

[0033] It should be noted that the sand storage mechanism 10 is used to store processed sand, and its multiple sand storage tanks 11 and connecting ports 12 facilitate the classification and flow of sand. The processing mechanism 20 includes a vibrating feeder 21, a crusher 22, and a screening machine 23, thereby realizing the conveying, crushing, and screening of sand. Specifically, the vibrating feeder 21 uniformly conveys the sand blocks to be processed to the crusher 22, ensuring the continuity and uniformity of the processing process. The crusher 22 crushes the sand blocks, and its discharge port is connected to the feed port of the screening machine 23 to realize the continuous processing of sand particles. The screening machine 23 classifies the crushed sand particles and returns the sand particles that do not meet the requirements to the crusher 22 for reprocessing through the circulation port to ensure the uniformity of sand particle size. The control center 30 serves as the processing center of the entire device, controlling the start and stop of the sand storage mechanism and the processing mechanism 20 to ensure the stable operation of the device.

[0034] Based on the above embodiments, the vibrating feeder 21 includes a vibrating drive component 211 and a feeding trough 212. The vibrating drive component 211 is disposed at the bottom of the feeding trough 212, which holds sand blocks to be processed. The discharge port of the feeding trough 212 is connected to the feed port of the crusher 22. Specifically, the vibrating drive component 211 is usually composed of an electric motor and a vibrator. The electric motor provides power, and the vibrator converts the rotational motion into linear vibration, causing the feeding trough 212 to vibrate. The feeding trough 212 is a container that holds the sand blocks to be processed. Its bottom is connected to the vibrating drive component 211 to transmit vibration and ensure that the sand blocks can move forward smoothly under the action of vibration and continuously and evenly enter the crusher 22 for crushing.

[0035] Based on the above embodiment, the feeding trough 212 is provided with a sand stirring rod 213 and a sand leakage plate 214. The axis of the sand stirring rod 213 is set along the feeding direction, and multiple sand stirring plates 215 are evenly spaced on the outer shaft surface of the sand stirring rod 213. The sand leakage plate 214 is set at the bottom of the sand stirring rod 213. The axis of the sand stirring rod 213 is set along the feeding direction to ensure that the rotation direction of the sand stirring rod 213 is consistent with the conveying direction of the sand block. This helps to drive the sand stirring plates 215 to rotate and move, thus pushing the sand block forward and preventing the sand block from accumulating or agglomerating in the feeding trough 212. This ensures that the sand block can pass through the feeding trough 212 smoothly. The sand leakage plate 214 is set to perform preliminary screening of impurities in the sand block, preventing impurities from entering the next stage of the processing, thereby improving the crushing efficiency and the quality of the final sand particles.

[0036] Based on the above embodiment, a plurality of sand leakage holes 214a are evenly distributed on the sand leakage plate 214; the even distribution of sand leakage holes 214a on the sand leakage plate 214 helps to uniformly screen sand blocks when passing through the sand leakage plate 214 and avoid local blockage; wherein, the hole size, number and distribution of sand leakage holes 214a should be set according to the screening requirements, and no specific limitation is made here.

[0037] Based on the above embodiments, the cross-sectional shape of the sand leakage hole 214a is a strip-shaped waist-shaped hole, which provides a larger passage area to ensure that the sand blocks entering the crusher 22 are all large-volume sand blocks, thus ensuring the uniformity and consistency of the final sand particles.

[0038] Based on the above embodiments, the crusher 22 includes a crushing chamber 221 and a crushing drive component 222. The crushing drive component 222 is electrically connected to the crushing chamber 221. The crushing chamber 221 is located between the crushing drive components 222, and the feed inlet of the crushing chamber 221 is connected to the discharge outlet of the vibrating feeder 21. The crushing chamber 221 is the core component of the crusher 22. It contains crushing tools for crushing sand blocks. The crushing drive component 222 provides power to the crushing tools inside the crushing chamber 221, ensuring a stable power supply for the crushing tools and achieving continuous crushing.

[0039] Based on the above embodiments, the screening machine 23 includes a primary screening chamber 231, a transition trough 232, and a secondary screening chamber 233. The primary screening chamber 231 is arranged facing the discharge port of the crushing chamber 221. The transition trough 232 is located between the primary screening chamber 231 and the secondary screening chamber 233, connecting the discharge port of the primary screening chamber 231 and the inlet of the secondary screening chamber, respectively. The primary screening chamber 231 is the first stage of the screening process, used for preliminary screening of the crushed sand particles to remove larger sand lumps or impurities. The transition trough 232 is located... The primary screening chamber 231 and the secondary screening chamber 233 are connected by their discharge and inlet ports, ensuring that sand particles can be smoothly transferred from the primary screening chamber 231 to the secondary screening chamber 233. The secondary screening chamber 233 further screens the sand particles to ensure that the particle size of the sand particles is more uniform and meets the fine requirements of the casting process. This allows sand particles that meet the requirements of the casting process to be separated after screening, while sand blocks that do not meet the requirements of the casting process can be re-entered into the crushing chamber 221 through the circulation port for crushing. The impurities are treated as waste.

[0040] Based on the above embodiments, a transmission mechanism is also included. The transmission mechanism is located at the output end of the processing mechanism 20 and is transitionally connected to the sand storage mechanism 10. The sand particles processed by the processing mechanism 20 are transported from the processing mechanism 20 to the sand storage mechanism 10 to realize the automated transfer of sand particles.

[0041] Based on the above embodiments, the transmission mechanism includes a conveyor frame 41 and a conveyor drive 42. The conveyor frame 41 is located at the discharge port of the secondary screening chamber 233 and has a conveyor belt surface 411 arranged along its length. The conveyor drive 42 is fixedly arranged at one end of the conveyor frame 41 and is electrically connected to the conveyor belt surface 411. The conveyor drive 42 provides power to the conveyor belt surface 411, so that the conveyor belt surface 411 carries and conveys the processed sand particles. The conveyor frame 41 is used to support the conveyor belt surface 411 and ensure its stable operation, so that the sand particles are conveyed to the sand storage tank 11 for storage.

[0042] Based on the above embodiments, the control center 30 includes a control room and a control panel 31 and a monitoring device 32 installed in the control room. The monitoring device 32 is electrically connected to the sand storage mechanism 10, the processing mechanism 20 and the transmission mechanism. The control panel 31 is communicatively connected to the monitoring device 32. The monitoring device 32 includes a computer, a display and other electronic devices for real-time monitoring of the operating status of the sand processing device. Operators can input commands through the control panel 31 based on the information reflected by the monitoring device 32, such as starting, stopping, adjusting parameters, etc., to achieve refined control of each mechanism of the entire sand processing device.
