Description

Technical Field

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

[0002] Quartz sand is quartz particles produced by processing quartz stone through crushing, screening, and other processes. Quartz stone is a non-metallic mineral, whose main mineral component is silicon dioxide. Quartz sand can be classified according to quality into ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused quartz sand, and silica powder, etc. The processing of natural quartz minerals often employs wet processes such as crushing, grinding, magnetic separation, scrubbing, and flotation, followed by drying treatment.

[0003] For example, a drum-type drying device for quartz sand, with announcement number "CN221924327U", uses a drum mechanism mounted on a frame. This mechanism, utilizing a supporting drum, filter plate, screw, base plate, pin, external gear ring, servo motor, and dewatering holes, employs a pin inserted into the dewatering holes. By turning the screw, the distance between the base plate and the supporting drum can be adjusted, thereby adjusting the depth of the conical pin inserted into the dewatering hole and thus the opening size of the hole. This allows for stepless adjustment of the dewatering holes, preventing large-scale blockage and facilitating efficient dewatering. The overall drying efficiency is further accelerated by incorporating air ducts and drying components. However, this method can only dry a fixed quantity of quartz sand. Typically, when drying a large quantity of quartz sand, operators must repeatedly operate the equipment, making continuous processing impossible. Furthermore, the quartz sand only tumbles unidirectionally through the drum, resulting in limited contact with hot air and requiring prolonged drying time, leading to low efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of being able to dry only a fixed amount of quartz sand, which is usually required to dry a large amount of quartz sand, requiring workers to operate the equipment back and forth, making continuous processing impossible, and the fact that the quartz sand can only be tumbled in one direction by the drum during drying, resulting in less contact between the quartz sand and the hot air, requiring a long working time to dry, thus leading to low work efficiency. Therefore, this invention proposes a special drum-type drying device for quartz sand.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drum-type drying device for quartz sand is designed, comprising a base plate and a shell. The upper end of the outer wall of the base plate is fixedly connected to the shell via a bracket. A quartz sand drying structure is provided on the upper left side of the outer wall of the shell, and a quartz sand stirring structure is provided on the lower left side of the outer wall of the shell. A first cylinder is fixedly connected to the left side of the inner wall of the shell, and a second cylinder is rotatably connected to the right side of the inner wall of the shell via a sealed bearing. The outer wall of the first cylinder is rotatably connected to the second cylinder via a sealed bearing. A cover plate is installed in the middle of the shell.

[0007] Preferably, the quartz sand mixing structure includes a servo motor, the output shaft of which is fixedly connected to a first toothed pulley via a reducer, the outer wall of the first toothed pulley being meshed with a second toothed pulley via a toothed belt, and a first gear being fixedly connected to the rotating part of the first toothed pulley, the outer wall of which is meshed with the second gear.

[0008] Preferably, the outer wall of the servo motor is fixedly connected to the outer casing via a bracket, and the inner wall of the second gear is fixedly connected to the second cylinder.

[0009] Preferably, the first gear rotating shaft is rotatably connected to the outer shell through a sealed bearing, the upper end of the first cylinder is fixedly connected to the feed inlet, and the outer wall of the feed inlet is fixedly connected to the outer shell.

[0010] Preferably, the quartz sand drying structure includes a hot air blower, the outer wall of the hot air blower is fixedly connected to the outer shell through a bracket, the inner wall of the hot air blower outlet is rotatably connected to the auger through a sealed bearing, the left end of the outer wall of the auger is fixedly connected to a second toothed pulley, and multiple mesh plates are fixedly connected to the inner wall of the auger, the right end of the mesh plate is rotatably connected to the plate body through a bearing.

[0011] Preferably, both ends of the plate are fixedly connected to the second cylinder, and a material box is placed on the upper right side of the outer wall of the bottom plate.

[0012] This utility model proposes a drum-type drying device specifically for quartz sand drying. The advantages are as follows: Through the coordination of the quartz sand stirring structure and the quartz sand drying structure, a servo motor starts and drives the first toothed pulley to rotate within the outer casing via a sealed bearing. This first toothed pulley then drives the first gear to rotate within the outer casing via a sealed bearing. The rotation of the first gear drives the rotation of the second gear, which in turn drives the second cylinder to rotate forward through the outer wall of the first cylinder and the inner wall of the outer casing via sealed bearings. Simultaneously, the rotation of the first toothed pulley drives the rotation of the second toothed pulley via a toothed belt. The pulley rotation drives the auger to rotate in opposite directions through sealed bearings inside the hot air blower outlet and plate. The second cylinder rotates forward to tumble the quartz sand, while the auger rotates in reverse to agitate it. The hot air blower starts and delivers hot air into the auger and sprays it into the quartz sand through multiple mesh plates. The servo motor ultimately drives the second cylinder to rotate forward and the auger to rotate in reverse, which can tumble the quartz sand in the forward direction and agitate it in the reverse direction, making the quartz sand more dispersed, increasing the contact area between the quartz sand and the hot air, and accelerating the drying process. At the same time, material can be discharged and replenished during the drying of quartz sand, allowing for continuous drying of quartz sand and effectively improving work efficiency.

[0025] See attached document Figure 1-5 The quartz sand drying structure 2 includes a hot air blower 201. The hot air blower 201 is designed to meet the actual working requirements.

The auger 202 can rotate inside the plate body 204 through the sealed bearing.

[0027] Working principle:

[0028] Quartz sand mixing and drying process:

[0029] When it is necessary to dry the quartz sand, the quartz sand is first introduced into the first cylinder 6 from the feed inlet 5, and then flows into the second cylinder 7 through the first cylinder 6. The interior of the first cylinder 6 and the second cylinder 7 are conical. The interior of the first cylinder 6 is processed with a slope, so that the quartz sand can flow into the second cylinder 7. The second cylinder 6 and the screw conveyor 202 turn and stir the quartz sand, which can make the quartz sand flow to the right.

[0030] Then, the external power supply of the servo motor 101 is connected. The output shaft of the servo motor 101 drives the first toothed pulley 102 to rotate through the reducer. The pulley rotates through the sealed bearing in the outer shell 4. Then, the first gear 103 is driven to rotate through the first toothed pulley 102 and rotates through the sealed bearing in the outer shell 4. The rotation of the first gear 103 drives the second gear 104 to rotate. The rotation of the second gear 104 drives the second cylinder 7 to rotate forward through the sealed bearing on the outer wall of the first cylinder 6 and the inner wall of the outer shell 4. At the same time, the rotation of the first toothed pulley 102 drives the second toothed pulley 105 to rotate through the toothed belt.

[0031] The rotation of the second toothed pulley 105 drives the auger 203 to rotate in the opposite direction through the sealed bearing inside the air outlet of the hot air blower 201 and the plate 204. The forward rotation of the second cylinder 7 tumbles the quartz sand, and the reverse rotation of the auger 203 can stir it in the opposite direction, making the quartz sand more dispersed and increasing the drying speed. At the same time, the external power supply of the hot air blower 201 is connected, and the hot air blower 201 starts to deliver hot air into the auger 202 and spray it into the quartz sand through multiple mesh plates 203. This movement can dry the dispersed quartz sand. The water vapor generated during the drying of the quartz sand can be discharged from the feed port 5 and the opening at the right end of the second cylinder 7.

[0032] The dried quartz sand flows through the second cylinder 7 into the hopper 8 for collection. The amount of quartz sand remaining in the first cylinder 6 and the second cylinder 7 is determined by the amount of quartz sand flowing out of the hopper 8. When the amount of quartz sand in the first cylinder 6 and the second cylinder 7 is low, it can be replenished through the feed inlet 5. In this way, the quartz sand can be continuously dried. The outer shell 4 is equipped with a cover plate 9 in the middle, which can be used to inspect the inner wall parts of the outer shell 4 when necessary.

[0033] Equipment maintenance:

[0034] The mesh plate 203, bearing and plate body 204 are detachable. When quartz sand is mixed into the mesh plate 203, the plate body 204 is disassembled to separate the bearing and mesh plate 203. The quartz sand mixed into the mesh plate 203 can be blown out from left to right by the hot air blower 201.
