[0024] Please see Figures 1 to 4 The present invention provides a feeding device for calcining sand according to one embodiment, comprising a conveying assembly 10 and a feeding assembly 20 mounted on the conveying assembly 10; the conveying assembly 10 includes a conveying bracket 11, a conveyor belt 12 mounted on the conveying bracket 11, and a feeding slide rail 13 mounted on the conveying bracket 11 in the same conveying direction as the conveyor belt 12; the feeding assembly 20 includes a feeding funnel 21 slidably mounted on the feeding slide rail 13, and anti-leakage plates 22 mounted on both sides of the feeding funnel 21; the anti-leakage plate 22 near one end of the conveyor belt 12 is arranged to abut against the conveyor belt 12.
[0025] The working principle of the feeding device for calcined sand of this utility model is as follows: When the feeding device for calcined sand is started, the conveyor belt 12 will start to run under the drive of the motor; at this time, calcined sand can be added into the feeding hopper 21; the feeding hopper 21 can move along the feeding slide rail 13 to a set position as needed, so as to more accurately control the feeding inlet of calcined sand; the calcined sand falls onto the conveyor belt 12 through the feeding hopper 21, and the conveyor belt 12 conveys the calcined sand forward according to the set direction and speed; during the feeding process, due to the synchronous operation of the conveyor belt 12, the structure of the feeding hopper 21 near the end of the conveyor belt 12 can effectively scrape the calcined sand on the conveyor belt 12, ensuring that the calcined sand is evenly distributed; at the same time, since the anti-leakage plates 22 on both sides of the feeding hopper 21 are set to abut against the conveyor belt 12, the calcined sand will not easily overflow from both sides of the conveyor belt 12 during the feeding process of the feeding hopper 21.
[0026] Compared to existing technologies, the feeding device for calcined sand of this utility model features a feeding funnel 21 designed near the conveyor belt 12, which effectively scrapes the calcined sand evenly onto the conveyor belt 12, ensuring uniform distribution. Understandably, the distance between the bottom outlet of the feeding funnel 21 and the conveyor belt 12 is equal to the thickness of the calcined sand. Leak-proof plates 22 on both sides of the feeding funnel 21, abutting against the conveyor belt 12, effectively prevent the calcined sand from overflowing from both sides, further improving the uniformity of the calcined sand distribution. The feeding funnel 21 can move along the feeding slide rail 13 to a specific position, achieving precise control of the feeding position and improving the accuracy of calcined sand delivery. The device is flexible in operation, allowing adjustment of the feeding position and speed according to different production needs, making it highly adaptable.
[0027] Please refer to Figure 2 and Figure 4The feeding assembly 20 also includes leak-proof guide rails 23 perpendicular to the conveying direction of the conveyor belt 12 and disposed on both sides of the feeding hopper 21, and leak-proof sliders 24 sliding on the leak-proof guide rails 23; the leak-proof plate 22 is installed on the leak-proof sliders 24. By setting leak-proof guide rails 23 perpendicular to the conveying direction of the conveyor belt 12 on both sides of the feeding hopper 21, and sliding the leak-proof sliders 24 on the leak-proof guide rails 23, the leak-proof plate 22 can be dynamically adjusted; in this way, the position of the leak-proof plate 22 can be flexibly adjusted according to the characteristics of the calcined sand and the conveying speed during the conveying process, so as to more effectively prevent the calcined sand from overflowing from both sides of the conveyor belt 12; the leak-proof sliders 24 can slide on the leak-proof guide rails 23 to ensure that the leak-proof plate 22 can cover the entire width of the conveyor belt 12 below the feeding hopper 21, thereby providing more comprehensive leak-proof protection; the leak-proof plate 22 prevents leakage by preventing leakage. The leak-proof slider 24 can move freely on the leak-proof guide rail 23. The position of the leak-proof plate 22 can be adjusted according to the different characteristics of the calcined sand and production needs to achieve a more precise leak-proof effect. For calcined sand with different particle sizes, shapes and viscosities, the position of the leak-proof plate 22 can be adjusted to ensure the best leak-proof effect. The leak-proof plate 22 can not only prevent the calcined sand from overflowing, but also play a role in assisting the shaping of the calcined sand on the conveyor belt 12 to ensure that the calcined sand is distributed more evenly. This dynamically adjustable leak-proof plate 22 design can work at different positions and angles to further optimize the distribution of calcined sand.
[0028] The conveyor belt 12 also includes a loading end 120 and a discharging end 121. A discharging funnel 21 is disposed on one side of the loading end 120 of the conveyor belt 12, and the conveying direction of the conveyor belt 12 is from the loading end 120 side to the discharging end 121 side. The placement of the discharging funnel 21 on one side of the loading end 120 of the conveyor belt 12 can ensure that the calcined sand is evenly distributed when it enters the conveyor belt 12. The discharging funnel 21 can move along the discharging slide rail 13 as needed to achieve more precise calcined sand dispensing. Since the calcined sand is added from a fixed position and evenly distributed on the conveyor belt 12, waste caused by uneven distribution of calcined sand can be reduced.
[0029] The conveyor belt 12 is inclined upwards from the feeding end 120 to the unloading end 121. This inclined design utilizes gravity to allow the calcined sand to slide more smoothly downwards upon entering the conveyor belt 12, reducing accumulation at the feeding end 120. The calcined sand, under the influence of gravity, is more evenly distributed on the conveyor belt 12, improving the uniformity of subsequent conveying and processing. The upward inclination reduces frictional resistance on the conveyor belt 12, making it easier to transport. This inclination significantly improves conveying efficiency, especially when conveying powdery, viscous, or easily agglomerated calcined sand. The inclination prevents backflow of the calcined sand due to vibration or stopping during transport, ensuring continuous forward transport and improving the continuity and stability of feeding. The upward inclination maintains a certain height difference on the conveyor belt 12, reducing the risk of spillage from both sides. The anti-leakage effect is particularly significant when combined with the unloading funnel 21 and the anti-leak plate 22.
[0030] The feeding slide rail 13 is located on one side of the feeding end 120, extending outwards from the side away from the feeding end 121. This arrangement allows the feeding hopper 21 to move over a wider range; operators can flexibly adjust the feeding position according to different production needs, ensuring more precise feeding of calcined sand; the feeding device used for calcined sand can adapt to production lines of different lengths and layouts, improving the equipment's versatility and flexibility; the outward extension of the feeding slide rail 13 prevents the feeding hopper 21 from staying near the starting point of the conveyor belt 12 for extended periods, reducing the amount of calcined sand... The accumulation at the feeding end 120 ensures uniform distribution of calcined sand; the extended portion of the feeding slide rail 13 provides a larger adjustment range, allowing operators to more precisely control the position of the feeding funnel 21 and reduce errors in calcined sand feeding; the extended design of the feeding slide rail 13 allows the anti-leakage plate 22 to cover a wider area, better preventing calcined sand from overflowing from both sides of the conveyor belt 12; the design of the feeding funnel 21 near the end of the conveyor belt 12 can better cooperate with the anti-leakage plate 22 to ensure that the calcined sand is scraped flat and evenly distributed on the conveyor belt 12.
[0031] Please refer to Figure 1 and Figure 2The feeding assembly 20 also includes a limiting member 25 for restricting the movement of the feeding hopper 21; the limiting member 25 includes a first limiting plate 250 installed on the feeding hopper 21 and a second limiting plate 251 installed on the conveying bracket 11; the first limiting plate 250 is provided with a plurality of first insertion holes 252; the second limiting plate 251 opposite to the first insertion holes 252 is provided with a plurality of second insertion holes 253; the limiting member 25 also includes a pin 254 for inserting into the first limiting plate 250 and the second limiting plate 251. By inserting the pin 254, the feeding funnel 21 can be fixed in a specific position to prevent it from moving during operation due to vibration or external force, thus improving the stability of the system. The design of the limiting member 25 can prevent the feeding funnel 21 from shifting due to operator error during operation, ensuring the continuity and reliability of the production process. The multiple insertion holes on the first limiting plate 250 and the second limiting plate 251 allow the feeding funnel 21 to be fixed in multiple different positions to adapt to different production needs. Operators can quickly adjust the position of the feeding funnel 21 by inserting or removing the pin 254, improving the flexibility and efficiency of the production process. The multiple insertion holes ensure that the position of the feeding funnel 21 is more accurate when fixed, reducing the error in calcining sand feeding caused by inaccurate positioning. By fixing the position of the feeding funnel 21, uneven distribution of calcining sand caused by the movement of the feeding funnel 21 can be avoided, reducing error accumulation and improving production quality.
[0032] Please refer to Figure 2 and Figure 4 The feeding assembly 20 also includes a scraper plate 26 installed on the feeding hopper 21 near one end of the conveyor belt 12 to level the calcined sand on the conveyor belt 12. The scraper plate 26 can level the calcined sand on the conveyor belt 12, ensuring that the calcined sand is evenly distributed on the conveyor belt 12; it can improve the consistency and quality of the production process; the scraper plate 26 can prevent the calcined sand from accumulating in a certain area on the conveyor belt 12, reducing production problems caused by uneven distribution; it can reduce downtime caused by calcined sand accumulation or uneven distribution, improving the continuity and efficiency of the production line; it helps to optimize subsequent processing and handling processes, reducing rework and waste caused by uneven calcined sand.
[0033] Please refer to Figure 1 and Figure 2The feeding device for calcined sand also includes a stirring assembly 30 installed on the conveying support 11. The stirring assembly 30 includes a stirring chamber 31 installed on the conveying support 11 and a mixer 32 installed in the stirring chamber 31. The stirring chamber 31 also includes an inlet 310 and an outlet 311, with the outlet 311 positioned opposite the discharge hopper 21. The stirring assembly 30 can uniformly mix the calcined sand, ensuring that various components are evenly distributed in the calcined sand; it can improve the quality and consistency of the final product; through stirring, it can reduce the stratification phenomenon caused by gravity during the conveying process of the calcined sand, ensuring the uniformity of the calcined sand in subsequent processing; it can realize continuous stirring and conveying of calcined sand, reducing downtime and waiting time in the production process and improving production efficiency; the stirring assembly 30 can also realize synchronous control of stirring and conveying, improving the automation level of the production process.
[0034] Please refer to Figure 2 and Figure 3 The mixing assembly 30 also includes a discharge opening and closing gate 33 with a rotating shaft mounted on the mixing chamber 31 for opening and closing the discharge port 311. By opening and closing the discharge opening and closing gate 33, the flow rate and discharge time of the calcined sand can be precisely controlled to achieve timed and quantitative discharge; this can reduce waste caused by too much or too little calcined sand and improve the utilization rate of calcined sand.
[0035] The mixing assembly 30 also includes locking valves 34 rotatably mounted on the mixing chambers 31 on both sides of the discharge port 311; the locking valves 34 include a rotating part 340 rotatably mounted on the mixing chamber 31 and a locking part 341 mounted on the rotating part 340 for locking the discharge opening and closing gate 33; when the discharge opening and closing gate 33 blocks the discharge port 311, the rotating part 340 is rotated to make the locking part 341 abut against the discharge opening and closing gate 33 to achieve locking; when it is necessary to open the discharge opening and closing gate 33, the rotating part 340 is rotated to separate the locking part 341 from the discharge opening and closing gate 33 to achieve opening of the discharge opening and closing gate 33. The locking valve 34 is designed to ensure the sealing of the discharge opening and closing gate 33 when closed, preventing leakage of calcined sand during stirring and maintaining a clean working environment. The locking part 341 can be locked or separated from the discharge opening and closing gate 33 simply by rotating the rotating part 340, making operation simple, quick, and user-friendly. The locking valve 34 has a reasonable structural design, maintaining good locking performance even after multiple uses, ensuring long-term stable operation of the equipment. The various components of the locking valve 34 are compactly designed, facilitating disassembly and maintenance, reducing maintenance costs and time. It can adapt to discharge opening and closing gates 33 of different sizes and shapes, exhibiting high versatility and flexibility.
