Description

Technical Field

[0001] The utility model relates to the improvement of quartz sand purification and processing equipment, in particular to the improvement of a quartz sand high-temperature gas chlorination purification and cooling device. Background Art

[0002] High-purity quartz sand is a high-purity non-metallic mineral raw material with a particle size concentrated in the range of 0.1 to 0.45 mm produced by a series of physical and chemical purification technologies from natural quartz minerals. The raw ore of high-purity quartz sand is natural quartz ore. In addition to quartz, quartz ore usually contains a variety of impurity minerals, such as mica, feldspar, iron-titanium oxide, etc. Quartz itself often contains certain metal or non-metallic element impurities and fluid impurities due to crystal structure defects or fine cracks. Most impurities can be removed by flotation, magnetic separation, gravity separation, acid leaching, calcination and other means, but it is difficult to achieve the standard of less than 1ppm for certain elements in high-purity quartz sand.

[0003] The existing quartz sand high temperature gas chlorination purification device has only two to three or four heating zones and no stripping strips in the glass tube, which cannot achieve uniform heating. In addition, the quartz sand undergoes phase change and volume expansion during the heating process, which easily causes the quartz tube to break. Therefore, it is necessary to design a device that can effectively purify quartz sand, heat evenly and produce continuously to meet user needs. Utility Model Content

[0004] The utility model aims to provide a quartz sand high-temperature gas chlorination purification and cooling device in view of the defects and shortcomings of the prior art, which can evenly heat and gasify the internal quartz sand. High-purity quartz sand purified to 99.999% can be obtained by the device, and the overall equipment structure is relatively simple. The inlet and outlet of hydrogen chloride gas are collected in a closed device, which will not pollute the environment and will not affect the health of workers.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it comprises a main furnace body 1, a furnace body support 2, a feeding mechanism 3, a rotating quartz tube 4, a rotating driving device 5, a discharging mechanism 6, a cooling mechanism 7, a cooling mechanism support 8, a cooling mechanism driving device 9, and a discharging port 10. The main furnace body 1 is tiltedly arranged on the furnace body support 2, and the cooling mechanism 7 is tiltedly arranged on the cooling mechanism support 8; a plurality of rotating quartz tubes 4 are arranged in the main furnace body 1, and the inlet end of the rotating quartz tube 4 is connected to the feeding mechanism 3, and the feeding mechanism 3 is supported on the main furnace body 1 through a supporting seat 31, and the rotating driving device 5 is arranged at the bottom of the main furnace body 1. The driving end of the rotating quartz tube 4 is connected to the rotating driving device 5 through gears and chains, the discharging mechanism 6 is fixedly arranged at the discharging end of the rotating quartz tube 4, an air inlet pipe 61 is arranged on the outlet of the discharging mechanism 6, and an air outlet pipe 32 is arranged on the feeding mechanism 3; the feeding hopper 71 of the cooling mechanism 7 corresponds to the discharging end of the rotating quartz tube 4, the cooling mechanism 7 is connected to the cooling mechanism driving device 9 through a chain transmission, the cooling mechanism driving device 9 is arranged at the bottom of the cooling mechanism 7, the discharging port 10 of the cooling mechanism 7 is lower than the feeding hopper 71, and heating silicon carbon rods are arranged below the rotating quartz tube 4, and the heating silicon carbon rods are arranged in multiple groups.

[0006] The main furnace body 1 is supported on the furnace body bracket 2 by several supporting lifting devices 21. The supporting lifting devices 21 include a lifting screw 211, a hinge seat 212, and a fixing nut 213. The hinge seat 212 is fixed on the main furnace body 1. The top of the lifting screw 211 is hinged to the hinge seat 212. The lifting screw 211 passes through the fixing nut 213, and the fixing nut 213 is fixed on the furnace body bracket 2. The feeding end of the main furnace body 1 is higher than the discharging end of the main furnace body 1 through the adjustment support of multiple supporting lifting devices 21. The main furnace body 1 is installed in an inclined manner, and the inclination angle is adjusted according to the actual use situation. The quartz tube is installed on the supporting wheel and equipped with a driving sprocket, and a material strip is arranged inside the tube. Under the drive of the motor and the speed change of the reducer, the quartz sand can be rolled back and forth in the rotating quartz tube 4 to make it heated and gasified evenly. The hydrogen chloride gas enters from the air inlet pipe 61 at the discharge end of the rotating quartz tube 4 and is discharged from the air outlet pipe 32 on the feeding mechanism 3. Since the main furnace body and the rotating quartz tube have an inclination angle, the quartz sand enters from a high place and is discharged from a low place under the action of the angle difference and the rotating gravity, and the hydrogen chloride gas enters from a low place and is discharged from a high place.

[0007] The feeding mechanism 3 is provided with a feeding hopper 33 , and the number of the feeding mechanisms 3 is the same as the number of the rotating quartz tubes 4 in the main furnace body 1 .

[0008] A hydrogen chloride gas outlet pipe 32 is provided on the support seat of the feeding mechanism 3, and a hydrogen chloride gas inlet pipe 61 is provided at the outlet of the discharging mechanism 6. The hydrogen chloride gas enters through the inlet pipe 61 at the discharging end of the rotating quartz tube 4 and is discharged through the outlet pipe 32 on the feeding mechanism 3. The outlet end is higher than the inlet end. The outlet pipe 32 can be connected to a hydrogen chloride gas collecting device to prevent the hydrogen chloride gas from leaking and protect the safety of the staff.

The heating silicon carbon rod can heat the quartz sand and gas in the rotating quartz tube continuously and evenly. The rotating quartz tube is installed on the supporting wheel and equipped with a driving sprocket. The tube is provided with a material strip. Under the drive of the motor and the speed change of the reducer, the quartz sand can be rolled back and forth to make it heated and gasified evenly. The hydrogen chloride gas enters from the discharge pipe and is discharged from the feed. Since the furnace body and the pipeline have an inclined angle, the quartz sand enters from a high place and is discharged from a low place under the action of the angle difference and the rotating gravity, and the hydrogen chloride gas enters from a low place and is discharged from a high place. Since the high temperature in the tube affects the quartz sand when it is discharged, it is also high-temperature sand. The discharged high-temperature sand needs to enter the cooler for cooling. After cooling, 99.999% high-purity quartz sand can be obtained. Hydrogen chloride gas is a chemical gas and needs to be processed by a collection and filtering device when discharged, so as to protect the health of the operator and the purpose of protecting the environment.

[0012] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: it can evenly heat and gasify the internal quartz sand, and high-purity quartz sand purified to 99.999% can be obtained through the device, and the overall equipment structure is relatively simple, and the inlet and outlet of hydrogen chloride gas are collected in a closed device, which will not cause pollution to the environment and will not affect the health of the staff.
