Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of drying equipment, specifically a quartz sand drying device. Background Technology
[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. It is an important industrial mineral raw material, a non-hazardous chemical, and is widely used in glass, casting, ceramics and fireproofing materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction chemicals, plastics, rubber, abrasives, filter media, and other industries.
[0003] When the moisture content of quartz sand exceeds 1%, water forms "water bridges" between particles, causing them to agglomerate through capillary forces. This is especially true for fine-grained quartz sand (e.g., <0.1mm), which has a large specific surface area, making it even more difficult for internal moisture to evaporate after agglomeration. Traditional drying equipment struggles to effectively separate agglomerated particles when processing moist quartz sand, resulting in uneven heating of the material. Slow evaporation of moisture in the core agglomerated areas significantly prolongs the overall drying time and reduces drying efficiency. Furthermore, existing drying equipment is generally limited by space constraints and energy costs, making it difficult to simultaneously expand equipment volume and heat exchange area. This prevents the material from fully contacting the heat source within a limited space, further exacerbating uneven drying. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0028] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.
[0029] See Figures 1-3 This embodiment provides a quartz sand drying device, comprising:
[0030] Drying oven 1;
[0031] The feeding box 2 is fixedly installed on the top wall of the drying box 1, and the feeding pipe is provided on the bottom wall of the feeding box 2;
[0032] The dispersing mechanism is located inside the feeding box 2 and is used to crush and disperse the partially agglomerated quartz sand entering the feeding box 2.
[0033] The feeding pipe 3 is rotatably mounted on the top wall of the feeding box 2;
[0034] The bulk material pipe 4 is provided on the feeding pipe 3 in multiple sets. The multiple sets of bulk material pipes 4 are of different lengths and are inclined. The inclined bulk material pipe 4 makes it easier to feed quartz sand.
[0035] Multiple sets of conveying troughs 5 are provided along the height direction of the drying box 1. The upper end of the conveying trough 5 is open to receive quartz sand. One end of the conveying trough 5 is provided with a discharge pipe 6. The discharge pipes 6 of two adjacent sets of conveying troughs 5 are located at opposite ends of the conveying trough 5. The lowermost set of discharge pipes 6 penetrates the bottom wall of the drying box 1. The discharge pipes 6 are used to output the contents of the conveying trough 5. By cooperating with multiple sets of conveying troughs 5 arranged vertically along the height direction of the drying box 1, the drying path of the quartz sand is extended, and the drying quality of the quartz sand is improved.
[0036] The conveyor shaft 7 is rotatably mounted inside the material conveying trough 5;
[0037] The spiral conveying blades 8 are mounted on the conveying shaft 7. The spiral conveying blades 8 in the two adjacent sets of conveying troughs 5 are in opposite directions. By setting the spiral conveying blades 8 in opposite directions, the quartz sand in the two adjacent sets of conveying troughs 5 can be conveyed in opposite directions to ensure that the conveying direction of the quartz sand is compatible with the setting direction of the discharge pipe 6. Furthermore, the spiral conveying blades 8 simultaneously realize the conveying and stirring of the quartz sand in the conveying trough 5. During the conveying process, the stirring agitates the quartz sand in the conveying trough 5, thereby improving the uniformity of heating of the quartz sand.
[0038] It should be noted that in this embodiment, the longitudinal section of the conveying trough 5 is circular in side view. The circular conveying trough 5 cooperates with the spiral conveying blade 8 to convey the quartz sand. At the same time, the diameter of the conveying trough 5 is smaller than the width of the drying box 1. Through the size difference between the diameter of the conveying trough 5 and the width of the drying box 1, the hot airflow can be ensured to rise from the bottom of the drying box 1 to the top of the drying box 1.
[0039] Specifically, see Figure 1 In this embodiment, the upper end of the feeding pipe 3 is provided with a feeding hopper 9, and the top wall of the feeding box 2 is fixedly provided with a rotating motor 10. The output end of the rotating motor 10 is fixedly provided with a driving bevel gear 11, and the feeding pipe 3 is fixedly provided with a driven bevel gear 12. The driving bevel gear 11 and the driven bevel gear 12 mesh. Through the meshing of the driving bevel gear 11 and the driven bevel gear 12, the rotating motor 10 drives the feeding pipe 3 to rotate. When the feeding pipe 3 rotates, it completes the multi-position dispersion feeding of quartz sand through multiple dispersing pipes 4 of different lengths.
[0040] Specifically, see Figure 1 and Figure 3 In this embodiment, a material dispersing hole 13 is provided in the middle of the bottom wall of the feeding pipe 3. The material dispersing hole 13 is used in conjunction with multiple sets of material dispersing pipes 4 of different lengths to achieve the dispersed feeding of quartz sand at different positions. The dispersing mechanism is used to efficiently crush and disperse the agglomerated quartz sand, so that the quartz sand enters the drying box 1 in a dispersed state.
[0041] Specifically, see Figure 1In this embodiment, the dispersion mechanism includes a dispersion motor 14, a dispersion shaft 15, and a dispersion rod 16. The dispersion motor 14 is fixedly mounted on the side wall of the feeding box 2, and the dispersion shaft 15 is rotatably mounted on the side wall of the feeding box 2. One end of the dispersion shaft 15 is connected to the output end of the dispersion motor 14, and the dispersion rod 16 is mounted on the dispersion shaft 15. When the dispersion shaft 15 drives the dispersion rod 16 to rotate, it knocks and disperses the blocky quartz sand fed by the feeding pipe 3.
[0042] Specifically, see Figure 1 In this embodiment, belt pulleys are fixedly provided on both the dispersing shaft 15 and the conveying shaft 7. Drive belts 17 are sleeved on two adjacent sets of belt pulleys. Under the action of the drive belts 17, the dispersing shaft 15 drives multiple sets of conveying shafts 7 to rotate, and the conveying shafts 7 drive the spiral conveying blades 8 to rotate, thereby completing the conveying of quartz sand.
[0043] Specifically, see Figure 1 In this embodiment, the lower part of the drying box 1 is connected to an air inlet system 18, and the upper part of the drying box 1 is connected to an exhaust system 19. The air inlet system 18 provides constant temperature hot air into the drying box 1, and the exhaust system 19 discharges the humid waste gas in the drying box 1 and recovers the quartz sand. Both the air inlet system 18 and the exhaust system 19 are existing mature technologies. For example, the air inlet system 18 includes a hot air extractor and a heater, and the exhaust system 19 includes a humid air extractor and a dust removal device (such as a bag filter or a cyclone separator).
[0044] The working principle of the quartz sand drying device provided in this embodiment is as follows:
[0045] The air intake system 18 and exhaust system 19 work together to provide a stable drying environment inside the drying chamber 1. Quartz sand is fed into the feeding box 2 from the feeding hopper 9. Quartz sand that has been stored for a long time may clump together. Driven by the rotation of the rotating motor 10, the driving bevel gear 11 rotates. The meshing of the driving bevel gear 11 and the driven bevel gear 12 drives the feeding pipe 3 to rotate. The rotating feeding pipe 3 disperses the quartz sand evenly into the feeding box 2 through the dispersing pipes 4 of varying lengths. The dispersing motor 14 drives the dispersing shaft 15 to rotate. The rotating dispersing shaft 15 drives the dispersing rod 16 to beat and disperse the quartz sand, thus dispersing the clumps of quartz sand. Quartz sand enters the uppermost set of conveying troughs 5 through the feed pipe. Driven by the drive belt 17, the conveying shaft 7 rotates, which in turn drives the spiral conveyor blades 8. The spiral conveyor blades 8 convey the quartz sand within the conveying troughs 5. Furthermore, the discharge pipe 6 facilitates continuous conveying of the quartz sand within the multiple sets of conveying troughs 5. The coordination of these multiple conveying troughs extends the conveying path of the quartz sand, increases the heat exchange area, and improves the drying quality. Simultaneously, the spiral conveyor blades 8 agitate the quartz sand within the conveying troughs 5 during the conveying process, enhancing the uniformity of the quartz sand's heating and drying.
