Description

Technical Field

[0001] This utility model relates to the field of sand baking technology, and in particular to a baking component for sand baking. Background Technology

[0002] Drainage sand is a functional material used in the steel smelting and casting industries, primarily composed of silica sand. It plays a crucial role in the drainage operation of ladles or casting molds, ensuring the smooth flow of molten steel or metal. Drying is necessary because drainage sand may absorb moisture during storage or transportation. The presence of moisture affects its drainage performance; drying effectively removes moisture, improves its purity, and ensures the stability of its physical and chemical properties, thereby enhancing its drainage function and improving drainage efficiency.

[0003] The guiding sand enters the heating chamber through the feeding device. After the heating element is activated, the temperature of the heating chamber gradually rises. During the heating process, the ventilation system continuously introduces fresh air and exhausts waste gas. When the temperature reaches the set baking temperature (e.g., 200-300℃ depending on the composition and process requirements of the guiding sand), it is maintained for a period of time (e.g., 30-60 minutes) to allow the moisture in the guiding sand to evaporate fully and achieve the required physical and chemical properties. After baking is complete, the valve of the discharge device is opened to discharge the guiding sand.

[0004] In the prior art, some baking devices directly put sand into an empty oven and then heat it at high temperature. However, the sand piles up and the sand inside is not dried thoroughly, which affects the processing efficiency. To address this problem, a sand-guiding baking component is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a baking component for guiding sand, which aims to improve the problem in the prior art where sand piles up and the internal sand is not thoroughly dried, affecting processing efficiency.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of a baking assembly for guiding sand, including a heating box 1. The heating box 1 serves as the core containing area of ​​the entire device, bearing the responsibility of containing the guiding sand to be baked and providing a stable heating environment. A motor 2 is fixedly connected to the left side of the heating box 1, serving as the starting point of the power source for the entire device. A fixed column 3 is fixedly connected to the drive end of the motor 2, and a sector gear 6 is fixedly connected to the other end of the fixed column 3. One end of the sector gear 6 is tightly connected to the drive end of the motor 2 and rotates synchronously with the motor 2; the other end is precisely fixed to the sector gear 6, enabling the sector gear 6 to rotate stably around the fixed column 3 as its axis.

[0033] The sector gear 6 is externally fixedly connected to a protruding post 7, and the heating box 1 is internally rotatably connected to an adjusting wheel 8. The adjusting wheel 8 is externally fixedly connected to a lever 9. The sector gear 6 is additionally welded with a protruding post 7. The protruding post 7 is made of the same material as the gear, has a smooth surface, and is scientifically positioned so that it can precisely contact and separate from the lever 9. This allows for precise control of the rotation time and pause interval of the heating plate 4, enabling the orderly tumbling of the sand inside the heating box 1. The external teeth of the sector gear 6 and the external teeth of the adjusting wheel 8 are meshed. When the sector gear 6 rotates, the meshing transmission of the teeth stably drives the adjusting wheel 8 to rotate.

[0034] A heating plate 4 is fixedly connected to the outside of the adjusting wheel 8. The heating plate 4 is externally rotatably connected to the inner wall of the heating box 1, and internally rotatably connected to the outside of the fixed column 3. One end of the heating plate 4 is welded to the adjusting wheel 8, with the rotation of the adjusting wheel 8 as the driving source. The middle part is nested on the outside of the fixed column 3 through a special bearing, which can rotate flexibly around the fixed column 3 without hindering the transmission of power by the fixed column 3. The other end is rotatably connected to a bushing pre-set on the inner wall of the heating box 1 to ensure smooth rotation and to turn the sand in the box in all directions without dead angles, so as to avoid the sand from accumulating and clumping, and to ensure that every grain of sand is fully baked.

[0035] The outer side of lever 9 contacts the outer side of protruding post 7. The key function of lever 9 is to precisely contact and cooperate with protruding post 7. Whenever lever 9 touches protruding post 7, it is like triggering an instruction to push heating plate 4 to start a new round of rotation, precisely controlling the timing of sand turning, and ensuring that the sand baking process is orderly. A protective box 5 is fixedly connected to the left side of heating box 1. The outer side of lever 9 is rotatably connected to the inner wall of protective box 5, effectively blocking the high temperature hot air and flying sand particles in heating box 1 from invading lever 9 and surrounding transmission components. A transmission component is set on the outer side of fixed post 3, which can provide power to component components.

[0036] A drive wheel 10 is fixedly connected to the outside of the fixed column 3. A belt 11 is fitted around the outside of the drive wheel 10. A driven wheel 14 is fixedly connected to the outside of the connecting column 13. The belt 11 is flexible, has strong tensile strength, and a fine surface texture, which increases the friction with the drive wheel 10 and the driven wheel 14, ensuring accurate and reliable power transmission. The inner wall of the other end of the belt 11 is fitted around the outside of the driven wheel 14, precisely matching the belt 11 and the driven wheel 14, so that the power of the fixed column 3 is smoothly output to the belt 11 transmission link. The end of the connecting column 13 away from the driven wheel 14 is rotatably connected to the inside right side of the feeding box 12. After receiving the power from the belt 11, it drives the connecting column 13 to rotate, introducing the power into the component assembly, realizing the linkage between the heating and feeding links, and ensuring that the sand is discharged in a timely and quantitative manner after baking.

[0037] Reference Figure 4 The bottom of the heating box 1 is equipped with a weighting component to prevent material accumulation. The weighting component includes a feeding box 12, the top of which is fixedly connected to the bottom of the heating box 1. The feeding box 12 has a funnel-shaped structure that is wider at the top and narrower at the bottom, which facilitates the concentrated falling of sand. A connecting column 13 is rotatably connected inside the feeding box 12, and a rotating column 15 is fixedly connected to the outside of the connecting column 13. Multiple feeding slots 16 are opened on the outside of the rotating column 15. One end is fixed to a driven wheel 14 to obtain transmission power; the other end is firmly connected to the rotating column 15 to transmit power to the rotating column 15, driving it to rotate, so as to realize the periodic receiving and discharging action of the feeding slots 16.

[0038] The feeding box 12 has two screen plates 17 fixedly connected inside. The rotating column 15 is rotatably connected to the bottom of the screen plates 17. It can not only block large particles or clumps of sand that are not fully baked and allow them to flow back to the heating box 1, but also allow qualified sand to fall smoothly into the feeding trough 16, playing a key role in screening and filtering, ensuring that the quality of the fed sand is uniform and meets the standards. The bottom of the heating box 1 is fixedly connected to the inlet 18 for easy pouring of sand. The bottom of the feeding box 12 is fixedly connected to the discharge port 19, which coordinates with the feeding rhythm of the rotating column 15 to achieve stable and quantitative discharge, meeting the requirements of subsequent production and packaging processes. The rotating column 15 rotates at a uniform speed under the drive of the connecting column 13. When the trough is facing upward, it receives the sand that leaks from the screen plates 17. When it rotates downward, it accurately pours the sand into the discharge port 19, and works with the valve to achieve quantitative discharge.

[0039] Working principle: First, sand is put into the heating box 1 through the feed port 18. Then, the motor 2 is started. Under the drive of the motor 2, the fixed column 3 rotates. The sector gear 6 rotates with the fixed column 3. Through the external teeth, it can drive the adjusting wheel 8 to rotate. When the adjusting wheel 8 rotates, it will drive the lever 9 to rotate. This will cause the heating plate 4 to rotate, turning the sand inside the heating box 1. The rotation time of the heating plate 4 is the same as the contact time between the lever 9 and the protruding column 7. This can prevent the sand from accumulating for a long time and also allow the turned sand to have a baking time.

[0040] After baking, the sand passes through the sieve plate 17 and enters the inside of the feeding box 12. At this time, the drive wheel 10 will rotate with the fixed column 3. The drive wheel 10 drives the driven wheel 14 to rotate through the belt 11, which in turn drives the connecting column 13 to rotate. When the sand falls into the inside of the feeding trough 16, it can be discharged quantitatively through the feeding port 19 while avoiding blockage.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
