[0002] Sand treatment and regeneration system is an environmentally friendly technology that can reuse sand or other granular materials in waste and reprocess them into high-quality sand products. This system can be used in industries such as construction, roads and mining, and has many advantages, such as reducing the consumption of natural resources, reducing production costs and reducing environmental pollution.

[0003] The existing sand processing and regeneration systems mostly rely on external instruments (devices) to detect the temperature or have basically no temperature measurement, so it is impossible to timely understand the temperature-related data inside the regeneration pipeline. Through on-site detection and comparison, it was found that the internal temperature of the pipeline before regeneration was about 15-20°C higher than the external temperature, and as the old sand enters the regeneration equipment, the grinding roller and the grinding disc are squeezed and rubbed, causing continuous heat, resulting in the internal temperature of the dust collection pipeline after regeneration. If it cannot be controlled and adjusted in time, it will bring hidden dangers to the safe operation of the equipment. Utility Model Content

[0027] Furthermore, each channel of the multi-channel temperature instrument 314 can independently set the alarm temperature, display the temperature measurement data in real time, and record the curve to save the temperature data through the controller, so as to facilitate the relevant analysis of the data;

[0028] Furthermore, by installing temperature measuring devices at the entrance and exit of the pipeline and at the front sand outlet of the regeneration equipment 1, and preparing a purging device to prevent particles from colliding and adhering to the probe surface to affect detection, the detection temperature signal is connected to the multi-channel detection instrument using a cable to realize real-time temperature monitoring, so as to avoid high-temperature spontaneous combustion of combustibles in the pipeline and sand storage due to the high sand temperature of the casting that cannot be normally discovered. A multi-channel temperature instrument 314 is installed at the work site. When any temperature detection channel reaches the alarm value, the on-site sound and light alarm will work. When another channel alarm is added, the controller controls and interlocks the power supply of the power supply equipment of the regeneration system to stop, so as to avoid fire hazards caused by no personnel to deal with the failure, thereby ensuring stable operation of the equipment.

[0030] It should be noted that, in this embodiment, when the existing regeneration system equipment is in operation, considering the sealing of the equipment, the internal temperature detection device cannot be installed inside the sand storage of the pipeline before regeneration due to the large amount of resin dust or combustible particles, and the detection device can only be installed outside the equipment or there is no detection device. In order to ensure the real-time monitoring of the temperature inside the pipeline and the sand storage and reduce the safety hazards of the equipment, multiple sets of plug-in thermal resistors 31 are added at the inlet and outlet pipes of the regeneration equipment 1, and multi-channel temperature instruments 314 and alarm devices are installed in the post operation area to realize real-time data monitoring and alarm functions;

[0031] Furthermore, the inserted thermal resistor 31 is connected to the front and rear regeneration pipes 2 by a threaded connection, which facilitates cleaning, replacement and maintenance of the inserted thermal resistor 31.

[0032] Furthermore, by installing temperature measuring devices at the entrance and exit positions of the front and rear regeneration pipelines 2 and the front sand outlet of the regeneration equipment 1, and making good anti-adhesion protection components 32 to prevent particles from colliding and adhering to the probe surface to affect detection, the detected temperature signal is connected to the multi-channel temperature instrument 314 by cable to realize real-time temperature monitoring, so as to avoid the high temperature of the casting sand falling, which cannot be normally discovered, thereby causing high-temperature spontaneous combustion of combustibles in the pipeline and sand storage. After multiple on-site observations and comparative tests, it is determined to install two sets of inserted thermal resistors 31 at the internal position of the pipeline and multiple sets of inserted thermal resistors 31 at the sand outlet of the sand storage, and to install a multi-channel temperature instrument 311 at the operation site for display. When any of the temperature detection channels reaches the alarm value, the on-site sound and light alarm will be activated. If another channel alarm is added, the control room fault alarm will be triggered, and the controller will control and interlock the power supply of the power supply equipment of the regeneration system to avoid fire hazards caused by no personnel handling when a fault occurs, and ensure the stable operation of the equipment. By verifying the above electrical control, the safe operation of the regeneration system can be better realized, and the risk of equipment failure and spontaneous combustion caused by the failure to be discovered in time due to high temperature can be avoided, thereby improving the equipment operation rate and safety.

[0034] When in use, insert the inserted thermal resistor 31 into the insertion hole 21 on the front and rear regeneration pipes 2, and fix the inserted thermal resistor 31 to the front and rear regeneration pipes 2 by threaded connection. The protective tube 321 protects the temperature measuring metal guide rod 313, and the blowing tube 322 regularly blows the temperature sensing element on the temperature measuring metal guide rod 313 to prevent particles from colliding with the temperature measuring metal guide rod 313 and adhering to the surface of the temperature measuring metal guide rod 313 to affect the detection, thereby ensuring the accuracy of the measurement. The detected temperature signal is connected to the multi-channel temperature instrument 314 by cable to realize real-time temperature monitoring.
