Description

Technical Field

[0001] This utility model relates to the technical field of drying equipment, specifically to a drum-type drying device for quartz sand drying. Background Technology

[0002] Quartz sand is a type of sand and gravel material, mainly obtained by crushing quartz stone. Due to its properties, it is used in a wide range of fields, from ordinary glass to high-precision semiconductors and photovoltaics, making it one of the most widely used materials.

[0003] Water is used in the preparation of quartz sand, which results in the quartz sand containing moisture, which is not conducive to storage and transportation. Therefore, drying is required. However, the traditional hot air drying method is not ideal, and the quartz sand is in a state of mutual accumulation, which leads to different drying rates between the inner and outer layers of quartz sand, and may even require rework. Therefore, a special drum-type drying device for quartz sand is proposed. Utility Model Content

[0004] The technical problem this invention aims to solve is that traditional hot air drying is inefficient and the quartz sand is piled up, resulting in different drying rates between the inner and outer layers, sometimes requiring rework. This invention provides a drum-type drying device specifically for drying quartz sand, which can scatter the quartz sand to avoid rework due to different drying rates between the inner and outer layers caused by the sand piling up, thereby improving the overall drying efficiency.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a special drum-type drying device for quartz sand drying, including vertical plates, a pair of vertical plates, a frame rotatably connected between the two vertical plates, a drying cylinder rotatably connected in the middle of the frame, a second motor detachably connected to the outer wall of one end of the frame, the output end of the second motor detachably connected to one end of the drying cylinder, a first motor detachably connected to the top side wall of one of the vertical plates, and the output end of the first motor detachably connected to the middle of one side wall of the frame.

[0006] As a preferred technical solution of this utility model, the drying cylinder has an inner cavity, the inner wall of the inner cavity is inlaid with a detachable electric heating tube, and the inner wall of the inner cavity is fixedly connected with a material feeding plate at equal intervals. The material feeding plate is in a vertical state, and the inner cavity has an inclined structure with different inclination angles.

[0007] As a preferred technical solution of this utility model, a steam exhaust pipe is fixedly connected to the side wall near one end of the drying cylinder, and an annular surrounding plate is fixedly connected to the inner wall of the steam exhaust pipe. The inner diameter of the surrounding plate is conical and a plug is inserted therein. A rubber sleeve is fixedly connected to the outer wall of the plug.

[0008] As a preferred technical solution of this utility model, a micro motor is detachably connected to one side of the outer wall of the exhaust pipe, a linkage shaft is rotatably connected inside the exhaust pipe, one end of the linkage shaft is detachably connected to the output end of the micro motor, a pressing plate is fixedly connected to the side wall of the linkage shaft, an outer ring plate is fixedly connected to the outer ring wall of one end of the plug head, and a spring is fixedly connected between the outer ring plate and the surrounding plate.

[0009] As a preferred technical solution of this utility model, a feed pipe is fixedly connected to one side wall near the top of the drying cylinder. The feed pipe communicates with the inner cavity and is threaded with a plug. A discharge port is opened through the bottom side wall of the drying cylinder, and a sealing plate is rotatably connected to one side edge of the discharge port via a micro-drive. A collection box is provided below the discharge port.

[0010] This invention has the following advantages: Starting motor number one can drive the frame to rotate, and as the frame rotates, the drying cylinder can rotate around the connection point between the frame and motor number one. At the same time, starting motor number two can drive the drying cylinder to rotate inside the frame, thus achieving multiple rotation effects. This drives the quartz sand inside the drying cylinder to rotate synchronously. Because a material feeding plate is fixed on the inner wall of the drying cylinder, it can help the quartz sand to be thrown out during rotation, thereby breaking up the quartz sand. This allows the quartz sand to fully contact the hot air, avoiding uneven drying and ensuring the drying rate of all quartz sand, thus improving the overall processing efficiency.

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] Please refer to the following: Figure 1-3This utility model discloses a special drum-type drying device for drying quartz sand, including vertical plates 1, a pair of vertical plates 1, a frame 3 rotatably connected between the two vertical plates 1, a drying cylinder 4 rotatably connected in the middle of the frame 3, a second motor 5 detachably connected to the outer wall of one end of the frame 3, the output end of the second motor 5 detachably connected to one end of the drying cylinder 4, a first motor 2 detachably connected to the top side wall of one of the vertical plates 1, the output end of the first motor 2 detachably connected to the middle of one side wall of the frame 3, an inner cavity 9 is opened inside the drying cylinder 4, an electric heating tube 10 is detachably connected to the inner wall of the inner cavity 9, and a material feeding plate 11 is fixedly connected at equal intervals to the inner wall of the inner cavity 9. The material feeding plate 11 is in a vertical state, and the inner cavity 9 is an inclined structure with different inclination angles.

[0015] The technical effect of this solution is as follows: Quartz sand is fed into the inner cavity 9 through the open feed pipe 6, and then the feed pipe 6 is sealed. Before this, the electric heating tube 10 is energized. As the electric heating tube 10 is energized, it generates heat, which gradually radiates and fills the inner cavity 9. The activation of motor 2 and motor 5 drives the drying cylinder 4 to rotate in a dual manner, thereby driving the quartz sand in the inner cavity 9 to be thrown up and scattered, thus avoiding the accumulation of quartz sand and avoiding the problem of different drying rates between the inner and outer layers of quartz sand due to accumulation. The dispersed quartz sand comes into full contact with the hot air, improving the uniformity and efficiency of drying.

[0016] A steam exhaust pipe 12 is fixedly connected to the side wall near one end of the drying cylinder 4. An annular surrounding plate 17 is fixedly connected to the inner wall of the steam exhaust pipe 12. The inner diameter of the surrounding plate 17 is tapered, and a plug head 18 is inserted into it. A rubber sleeve is fixedly connected to the outer wall of the plug head 18. A micro motor 14 is detachably connected to one side of the outer wall of the steam exhaust pipe 12. A linkage shaft 15 is rotatably connected inside the steam exhaust pipe 12. One end of the linkage shaft 15 is detachably connected to the output end of the micro motor 14. A [missing information - likely a component or material] is fixedly connected to the side wall of the linkage shaft 15. The outer ring wall of the pressing plate 16 and the plug head 18 is fixedly connected to the outer ring wall. A spring 20 is fixedly connected between the outer ring plate 19 and the surrounding plate 17. A feed pipe 6 is fixedly connected to the side wall of the drying cylinder 4 near the top. The feed pipe 6 communicates with the inner cavity 9. A plug is connected to the feed pipe 6 by internal thread. A discharge port 13 is opened through the bottom side wall of the drying cylinder 4. A sealing plate 7 is rotatably connected to one side edge of the discharge port 13 through a micro driver. A collection box 8 is set below the discharge port 13.

[0017] The technical effect of this solution is as follows: A steam exhaust pipe 12 is fixed on one side of the drying cylinder 4. When needed, the micro motor 14 is activated to adjust the orientation of the pressing plate 16 so that it is disengaged from above the plug head 18. Then, driven by the spring 20, the plug head 18 is pushed out from inside the surrounding plate 17. Steam is exhausted through the gap between the plug head 18 and the inner wall of the surrounding plate 17, so as to avoid the drying effect being affected by moisture in the inner cavity 9. The reverse linkage shaft 15 can drive the pressing plate 16 to press the plug head 18, thereby inserting the plug head 18 into the surrounding plate 17 to ensure the sealing of the inner cavity 9. The maximum gap between the plug head 18 and the surrounding plate 17 is also smaller than the size of the quartz sand, so as to prevent quartz sand from spilling out. After drying, the driver drives the sealing plate 7 to rotate, thereby exposing the discharge port 13. The dried quartz sand can then be discharged from the discharge port 13 and guided into the collection box 8 for collection along the sealing plate 7. When needed, the drying cylinder 4 can be driven to shake back and forth to improve the discharge effect.

[0018] Specifically, in use, the quartz sand to be dried is fed into the inner cavity 9, and then the feed pipe 6 is resealed. Then, the first motor 2 is started to drive the frame 3 to rotate, and the second motor 5 drives the drying cylinder 4 to rotate, thus achieving bidirectional rotation. The second motor 5 rotates independently to disperse the quartz sand in the inner cavity 9. The hot air generated by the electric heating tube 10 can fully dry the dispersed quartz sand, preventing the quartz sand from accumulating and affecting the drying effect. The micro motor 14 is started at regular intervals to drive the pressing plate 16 to rotate, thereby releasing the pressure on the plug head 18. Under the action of the spring 20, the plug head 18 will be pushed out from the surrounding plate 17, thus exposing the gap for steam to escape. Reversing the direction, the pressing plate 16 can press the plug head 18 back into the surrounding plate 17 to achieve sealing. After drying, the sealing plate 7 is opened to discharge the quartz sand from the discharge port 13 into the collection box 8.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
