The multiple sets of second rotating shafts 33 are connected by belts to ensure synchronous rotation. A placement plate 34 is installed on the support frame 11 to provide a mounting surface for the second motor 35. The shaft end of the second motor 35 on the placement plate 34 is connected to one of the sets of second rotating shafts 33 by a belt. When the second motor 35 starts, it drives the multiple sets of second rotating shafts 33 to rotate synchronously through belt drive, driving the conveyor belt to transport the raw materials within the device, delivering the pre-treated raw materials to the designated location. A collection tray 36 is provided at one end of the support frame 11 and connected to the support frame 11 to collect the raw materials that have been pre-treated and fall from the conveyor belt, so as to facilitate subsequent packaging or use in production.Multiple sets of foot pads 37 are installed at the bottom of the support frame 11 to increase the friction between the device and the ground, prevent the device from shifting during operation, play a shock absorption and buffering role, reduce the impact of device vibration on the surrounding environment, protect the device structure stability, and extend the service life of the device.

[0024] like Figures 2 to 4 As shown, when using this device, the user first places the support frame 11 in a suitable working area. As the core support structure of the entire device, the support frame 11 provides a stable installation foundation for all other components, ensuring that the entire raw material pretreatment process can be carried out smoothly.

[0025] The support frame 11 is equipped with multiple sets of support crossbars 12, which are secured to the support frame 11.

These fixing blocks 13 ensure that the connecting columns 14 can be securely installed on the support crossbars 12, thereby maintaining the stability of the entire structure.

[0026] Connecting columns 14 penetrate multiple sets of fixing blocks 13, and the connecting columns 14 are perpendicular to the bearing crossbars 12, serving to connect the fixing blocks 13 and the component distribution plates 15. The multi-component component distribution plates 15 installed on the connecting columns 14 are important components for the initial weighing of refractory castable raw materials. According to the different raw material proportions, users can place various raw materials on the corresponding component distribution plates 15 to achieve the initial quantitative division of the raw materials, thus preparing for the subsequent raw material mixing process.

[0027] Multiple sets of support crossbars 12 are equipped with cutting components, and guide frames 16 span across the multiple sets of support crossbars 12, guiding the movement of the upper and lower cutting plates 17. Guide grooves are provided at both ends of the support frame 11, cooperating with the guide frames 16 to define the movement trajectory of the upper and lower cutting plates 17. The user operates an electric push rod 19 on an L-shaped placement frame 18 on one side of the support frame 11. One end of the electric push rod 19 is connected to one end of the upper and lower cutting plates 17. Through the extension and retraction of the electric push rod 19, the upper and lower cutting plates 17 can be controlled to move vertically under the guidance of the guide grooves and guide frames 16, thus achieving the cutting operation of the raw material on the support crossbars 12. This allows for the control of the amount and timing of the raw material entering the next process, meeting the actual needs of different production stages for raw material quantity.

[0028] The instrument frame 21 is attached to the support frame 11. The instrument frame 21 provides space for the centralized installation of other functional components, making the entire device compact and orderly. An air-sealed material tank 22 is mounted on the instrument frame 21. This air-sealed material tank 22 serves as a temporary storage and transfer area for raw materials, undertaking the functions of buffering and distributing raw materials. The air-sealed material tank 22 is connected to the material cylinder 23, which is the channel through which raw materials enter the air-sealed material tank 22. A flow control valve 24 is installed between the air-sealed material tank 22 and the material cylinder 23. One end of the flow control valve 24 is connected to the material cylinder 23. By operating the flow control valve 24, the user can adjust the flow rate of raw materials flowing from the material cylinder 23 into the air-sealed material tank 22 according to actual production needs, ensuring that the raw materials enter the air-sealed material tank 22 according to the set ratio, thus guaranteeing the quality stability of the pretreated refractory castable.

[0029] The instrument frame 21 is also equipped with a collection tank 29, one end of which is connected to the air-sealed material tank 22, responsible for collecting the mixed raw materials flowing out of the air-sealed material tank 22. Multiple sets of flow direction guides 31 are provided on one side of the collection tank 29. These flow direction guides the raw materials in the collection tank 29 to different processing directions or the next process, meeting the diverse requirements of different production processes for raw material flow. Multiple sets of fixing rings 32 are threaded through the instrument frame 21, and the air-sealed material tank 22 is connected to these fixing rings 32 by bolts, ensuring the secure installation of the air-sealed material tank 22 and facilitating disassembly, maintenance, or replacement of the air-sealed material tank 22 when necessary, providing convenience for users to maintain and repair the device.

[0030] A collection tray 36 is provided at one end of the support frame 11. The collection tray 36 is connected to the support frame 11 and is used to collect the raw materials that have been transported from other parts of the device after a series of pre-processing steps. The collection tray 36 provides temporary storage space for the raw materials that have been pre-processed, making it convenient for users to carry out subsequent collection and packaging work, or to directly put them into the next production process.

[0031] The bottom of the support frame 11 is equipped with multiple sets of foot pads 37. These foot pads 37 increase the friction between the device and the ground, preventing the device from shifting due to vibration, external impact, or other factors during operation. At the same time, the foot pads 37 also have a certain shock absorption effect, which can reduce the impact of vibration generated during device operation on the surrounding environment, protect the structural stability of the device itself, extend the service life of the device, and create a stable pretreatment working environment for users.

[0032] The specific usage and function of this embodiment are as follows:

[0033] When using the device, the user first places the support frame 11 in a suitable location. The support frame 11 supports all components, ensuring stable pretreatment. The support crossbar 12 increases the bearing area and facilitates component installation. The fixing block 13 and connecting column 14 securely connect the dispensing plate 15. The user places the raw materials on the dispensing plate 15 according to the raw material ratio to complete the initial quantitative measurement. By operating the electric push rod 19 on the L-shaped placement frame 18, the upper and lower cutting plates 17 are controlled to cut the raw materials and adjust the amount entering the next process. The instrument frame 21 integrates the installation components. The flow control valve 24 between the air-sealed material tank 22 and the material cylinder 23 adjusts the raw material flow as needed. The first motor 26 drives the stirring rod 28 to stir the raw materials. The collection tank 29 collects the mixed raw materials and guides them to different processes through the flow guide 31. The second motor 35 drives the conveyor belt to transport the raw materials to the collection tray 36. The foot pads 37 prevent device displacement and dampen vibration, ensuring stable operation and extended lifespan of the device.
