Description

Technical Field

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

[0002] Quartz sand drying is an important step in the quartz sand processing, which aims to remove moisture from the quartz sand, improve its purity, and facilitate subsequent processing and applications.

[0003] The core principle of quartz sand drying is to evaporate the moisture in the quartz sand through heating. Depending on the heating method, it can be divided into two types: direct heating and indirect heating.

[0004] In the existing technology, such as the Chinese patent application number 202420241849.7 for a quartz sand drying device, the quartz sand is dried in a closed drying tank. After one batch is dried, it is discharged. This cannot form a continuous production line drying operation, which can easily affect the drying efficiency of large batches. Therefore, an improved quartz sand drying device is needed to address this problem. Utility Model Content

[0005] The purpose of this invention is to provide a quartz sand drying device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quartz sand drying device, comprising a transmission pipe, a spiral transmission rod movably disposed in the middle of the inner side of the transmission pipe via a bearing, and a drying mechanism for heating and drying quartz sand disposed on the outer side of the transmission pipe, the drying mechanism comprising a shell, a jacket, a heating wire, a worm gear fan, and a discharge port, the shell being fixedly disposed on the outer side of the transmission pipe, a jacket being disposed between the shell and the transmission pipe, a heating wire being fixedly disposed at the lower end of the surface of the transmission pipe, a worm gear fan being fixedly disposed at the upper end of the shell, the air inlet of the worm gear fan being interconnected with the interior of the shell, and a discharge port being fixedly disposed on one side of the lower end of the shell.

[0007] Preferably, a feed inlet is fixedly provided on one side of the surface of the transmission pipe, through which the quartz sand raw material to be dried can be conveyed into the transmission pipe.

[0008] Preferably, an electric motor is fixedly installed on one side of the transmission tube. The power output shaft of the electric motor is connected to the spiral transmission tube through a sprocket and a chain. The electric motor can easily drive the spiral transmission rod to rotate continuously, thereby transmitting the quartz sand inside the transmission tube upward.

[0009] Preferably, an insulation layer is fixedly provided on the outer side of the shell. The insulation layer can improve the heat insulation effect of the shell, thereby reducing the heat loss from the interlayer to the environment and ensuring that the heat is fully used for the drying of quartz sand.

[0010] Preferably, an isolation ring is fixedly provided on the outer surface of the transmission tube at the upper end of the heating wire. The isolation ring prevents the falling quartz sand from impacting the surface of the heating wire at high speed, thus protecting the heating wire.

[0011] Preferably, an air outlet is fixedly provided on one side of the worm gear fan, through which the worm gear fan can work to discharge the air inside the shell interlayer to the outside.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the feed inlet continuously adds the quartz sand to be dried into the transmission pipe, while the discharge outlet continuously discharges the dried quartz sand. This can form a continuous hot air drying operation, and the feeding and discharging do not interfere with each other. This allows for assembly line operation and improves processing efficiency.

[0014] 2. In this invention, the continuously falling, dispersed quartz sand and the continuously rising hot air flow form convection, which can quickly dry the quartz sand particles with hot air, significantly improving the drying effect. The hot air flow can quickly remove the moisture inside the quartz sand and discharge it to the outside of the device with the worm gear fan. Furthermore, the heating wire can not only heat the air flow, but also directly heat the inside of the transmission tube, so that the quartz sand is heated as soon as it enters the lower end of the transmission tube, preheating it in advance, which can further facilitate the subsequent hot air drying work.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a quartz sand drying device, including a transmission pipe 1, a spiral transmission rod 2 movably arranged in the middle of the inner side of the transmission pipe 1 via a bearing, and a drying mechanism for heating and drying quartz sand arranged on the outer side of the transmission pipe 1. The drying mechanism includes a shell 3, a jacket 4, an electric heating wire 5, a worm gear fan 6, and a discharge port 7. The shell 3 is fixedly arranged on the outer side of the transmission pipe 1, and the jacket 4 is arranged between the shell 3 and the transmission pipe 1. The electric heating wire 5 is fixedly arranged at the lower end of the surface of the transmission pipe 1. The worm gear fan 6 is fixedly arranged at the upper end of the shell 3. The air inlet of the worm gear fan 6 is interconnected with the interior of the shell 3. The discharge port 7 is fixedly arranged on one side of the lower end of the shell 3.

[0022] A feed inlet 8 is fixedly provided on one side of the surface of the transmission pipe 1, through which the quartz sand raw material to be dried can be conveyed into the transmission pipe 1.

[0023] A motor 9 is fixedly installed on one side of the transmission pipe 1. The power output shaft of the motor 9 is connected to the spiral transmission pipe 1 through a sprocket and a chain. The motor 9 can easily drive the spiral transmission rod 2 to rotate continuously, thereby transmitting the quartz sand inside the transmission pipe 1 upward.

[0024] An insulation layer is fixedly installed on the outside of the shell 3. The insulation layer can improve the heat insulation effect of the shell 3, so as to reduce the heat dissipation from the inside of the interlayer 4 to the environment and ensure that the heat is fully used for the drying of quartz sand.

[0025] An isolation ring 10 is fixedly provided on the outer surface of the transmission tube 1 at the upper end of the heating wire. The isolation ring 10 prevents the falling quartz sand from impacting the surface of the heating wire at high speed, thus protecting the heating wire.

[0026] The worm gear fan 6 has an air outlet 11 fixedly installed on one side. The air inside the interlayer 4 of the housing 3 can be discharged to the outside through the operation of the worm gear fan 6 via the air outlet 11.

[0027] Working Principle: The drying principle of this device is as follows: Quartz sand to be dried is added into the conveying pipe 1 through the feed inlet 8. Then, the quartz sand is conveyed upward by the spiral conveying rod 2. Since the upper end of the conveying pipe 1 is open, the quartz sand flows out in all directions after being conveyed to the upper end of the conveying pipe 1, and then enters the jacket 4 and falls freely under the action of gravity. This is to fully disperse the quartz sand to facilitate the subsequent hot air drying. At this time, the heating wire 5 is energized and the worm gear fan 6 is controlled to work. Then, the heating wire 5 heats the lower part of the jacket 4, and the worm gear fan 6 blows air to send out the air in the jacket 4 and the conveying pipe 1, creating a negative pressure inside the jacket 4. Then, outside air flows out from the outlet. Feed inlet 7 and feed outlet 8 continuously enter the device and come into contact with heating wire 5 to form hot air. Under the action of worm gear fan 6, hot air flows upward from bottom to top inside jacket 4. The continuously falling dispersed quartz sand and the continuously rising hot air flow form convection, which can quickly dry the quartz sand particles with hot air, significantly improving the drying effect. The hot air flow can quickly remove the moisture inside the quartz sand and discharge it to the outside of the device with worm gear fan 6. In addition, heating wire 5 can not only heat the air flow, but also directly heat the inside of transmission pipe 1, so that the quartz sand is heated and preheated as soon as it enters the lower end of transmission pipe 1, which can further facilitate the subsequent hot air drying work.

[0028] Finally, the dried quartz sand enters the discharge port 7 at the lower end of the jacket 4. Under the working vibration of the worm gear fan 6 and the motor 9, the dried quartz sand entering the lower end of the jacket 4 is discharged from the inclined discharge port 7. In this way, the feed port 8 continuously adds quartz sand to be dried into the transmission pipe 1, while the discharge port 7 continuously discharges the dried quartz sand. This can form a continuous hot air drying operation, and the feeding and discharging do not interfere with each other. This allows for assembly line operation to improve processing efficiency. Of course, this device only has one discharge port 7. If a large amount needs to be discharged each time and a higher working speed is required, without changing any of the mechanisms of this device, another discharge port 7 can be set on one side of the discharge port 7 or the width of the discharge port 7 can be increased.
