Description

Technical Field

[0001] This utility model relates to the field of quartz sand preparation technology, and in particular to an energy-saving and environmentally friendly quartz sand refining and drying equipment. Background Technology

[0002] Traditional quartz sand dryers, river sand dryers, and sand dryers belong to the same type of dryer equipment. They generally adopt a single-cylinder long cylinder and are quite similar to mineral powder dryers. They are mainly used for drying materials with a certain moisture content and particle size range. They are widely used in building materials, metallurgy, chemical industry, cement industry, and for drying various mineral powders, limestone, coal powder, quartz sand, clay, yellow sand, foundry sand, scrubbing sand, and various metal concentrates, tailings, and other materials that are not afraid of high temperatures and are not easily polluted by smoke and dust.

[0003] Announcement No. CN214065551U proposes an environmentally friendly and dust-proof quartz sand drying device. It changes the traditional horizontal placement of drying devices to a vertical placement, which greatly reduces the floor space and saves factory space. At the same time, a high-pressure hot air inlet is installed at the bottom of the drying device, and the hot air carries away the moisture in the quartz sand from bottom to top, resulting in better drying effect. Furthermore, an exhaust gas filtration device is also set up to adsorb most of the dust in the exhaust gas, preventing air pollution and benefiting environmental protection.

[0004] However, during the use of this device, the quartz sand at the bottom remains at the bottom during drying, and the stirring rod cannot move the quartz sand at the bottom to the top. As a result, the quartz sand at the bottom is constantly in contact with the hot air, causing the quartz sand at the bottom to dry quickly, while the quartz sand at the top remains relatively damp, resulting in poor drying effect. Therefore, an energy-saving and environmentally friendly quartz sand refining and drying device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an energy-saving and environmentally friendly quartz sand refining and drying equipment that can solve the problems in the background art.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: an energy-saving and environmentally friendly quartz sand refining and drying equipment, including a drying equipment shell 1, a feed hopper 2 fixedly connected to the surface of the drying equipment shell 1, a discharge hopper 3 provided on the surface of the drying equipment shell 1, a drive rod 9 rotatably connected inside the drying equipment shell 1, a fixed pipe 7 fixedly connected to the surface of the drying equipment shell 1, and the two connection points between the fixed pipe 7 and the drying equipment shell 1 are inclined, a rotating rod 8 rotatably connected inside the fixed pipe 7, a sprocket assembly provided on the surface of the drive rod 9 and the rotating rod 8, the sprocket assembly causing the drive rod 9 to rotate and the sprocket assembly to rotate, thereby causing the drive rod 9 and the rotating rod 8 to rotate simultaneously, an auger 18 fixedly connected to the surface of the rotating rod 8, and a microperforated plate 17 fixedly connected inside the drying equipment shell 1, the microperforated plate 17 allowing air to pass through below while blocking quartz sand particles above.

[0025] A motor 5 is installed on the top of the outer casing 1 of the drying equipment, and the output end of the motor 5 is fixedly connected to the drive rod 9 through a coupling.

[0026] A fixed shell 6 is fixedly connected to the surface of the outer shell 1 of the drying equipment. The sprocket assembly is located inside the fixed shell 6. The surfaces of the rotating rod 8 and the driving rod 9 are rotatably connected to the inside of the fixed shell 6. The output end of the motor 5 is also rotatably connected to the inside of the fixed shell 6. By setting the fixed shell 6, the sprocket assembly is covered, thereby preventing the sprocket assembly from being directly exposed to the outside world and protecting the sprocket assembly.

[0027] A hot air inlet pipe 4 is fixedly connected to the surface of the drying equipment shell 1. The hot air inlet pipe 4 is connected to an external air heating device. Hot air is introduced into the drying equipment shell 1 through the hot air inlet pipe 4 to dry the quartz sand. At the same time, an exhaust gas filter is installed on the surface of the drying equipment shell 1 to filter the exhaust gas and dust generated during the drying process, thereby protecting the environment. This is described in the comparative case and will not be explained further.

[0028] A sliding sleeve 14 is slidably connected to the surface of the drive rod 9. The interior of the sliding sleeve 14 is hexagonal. A fixing plate 19 is fixedly connected to the surface of the drive rod 9. The surface of the fixing plate 19 is slidably connected to the interior of the sliding sleeve 14. The fixing plate 19 is also hexagonal. A stirring rod 10 is fixedly connected to the surface of the sliding sleeve 14. Through the setting of the fixing plate 19, the drive rod 9 drives the fixing plate 19 to rotate. The fixing plate 19 drives the sliding sleeve 14 to rotate. At the same time, the sliding sleeve 14 can slide on the surface of the drive rod 9.

[0029] A connecting block 11 is fixedly connected to the bottom of the sliding sleeve 14. A connecting rod 12 is fixedly connected to the surface of the connecting block 11. A sliding frame 13 is fixedly connected to the surface of the connecting rod 12. The sliding frame 13 is T-shaped. A fixing block 16 is fixedly connected inside the drying equipment shell 1. An annular groove 15 is opened on the surface of the fixing block 16. The annular groove 15 is elliptical. The inner wall of the annular groove 15 is slidably connected to the surface of the sliding frame 13. The surface of the sliding sleeve 14 is slidably connected to the inside of the microporous plate 17.

[0030] Working principle: When it is necessary to dry the quartz sand, the quartz sand to be dried is poured into the interior of the drying equipment shell 1 through the feed hopper 2. The operator connects the external air heating device to the hot air inlet pipe 4, and then starts the motor 5. The motor 5 drives the drive rod 9 to rotate, which in turn drives the fixed plate 19 to rotate. This causes the fixed plate 19 to drive the sliding sleeve 14, which in turn drives the stirring rod 10 to rotate, stirring the quartz sand inside the drying equipment shell 1. At the same time, the hot air entering the equipment through the hot air inlet pipe 4 comes into contact with the quartz sand through the microporous plate 17, thus drying the quartz sand.

[0031] When the drive rod 9 rotates, the drive rod 9 drives the connecting group to rotate through the sprocket assembly, which in turn drives the rotating rod 8 to rotate, and the rotating rod 8 drives the auger 18 to rotate. Since the two connection points between the fixed pipe 7 and the outer shell 1 of the drying equipment are inclined, when the stirring rod 10 rotates to stir the quartz sand, some of the quartz sand will slide into the interior of the fixed pipe 7. As the auger 18 rotates, it transports the incoming quartz sand, and the quartz sand is discharged from the pipe above the fixed pipe 7, thus moving the quartz sand from the bottom to the top.

[0032] When the sliding sleeve 14 rotates, it drives the connecting block 11 to rotate, which in turn drives the connecting rod 12 to rotate. The connecting rod 12 then drives the sliding frame 13 to move, causing the sliding frame 13 to slide inside the annular groove 15. As the annular groove 15 is set, the sliding frame 13 drives the connecting rod 12, the connecting block 11, and the sliding sleeve 14 to move up and down. Consequently, the sliding sleeve 14 drives the stirring rod 10 to move up and down, further increasing the stirring range of the stirring rod 10 and improving the stirring effect of the device.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
