Description

Technical Field

[0001] This invention relates to the field of quartz sand purification technology, and more specifically, to a quartz sand purification apparatus and method based on microwave temperature control. Background Technology

[0002] Quartz sand is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is silicon dioxide. Quartz sand is milky white or colorless and translucent. Modern industry often uses quartz sand as a mineral raw material. In addition to quartz, quartz ore usually contains a variety of impurity minerals, such as mica, feldspar, and iron and titanium oxides. Quartz itself often contains certain metallic or non-metallic element impurities, as well as fluid impurities, due to crystal structure defects or micro-cracks. Therefore, quartz sand needs to be purified to meet the needs of different application scenarios.

[0003] Chinese Patent Application No. 202311630820.4 discloses a quartz sand purification device and a quartz sand purification method. The quartz sand purification device includes, for example: a main cavity with a microwave conversion component inside; a microwave output device connected to the main cavity; a quartz sand purification tube penetrating the main cavity, with both ends of the tube exposed on opposite sides of the main cavity; the microwave conversion component being sleeved on the quartz sand purification tube; and a preheating device extending into the quartz sand purification tube to preheat it. This invention uses a preheating device inserted into the quartz sand purification tube to rapidly raise the quartz sand purification tube to a predetermined temperature, thereby reducing the purification time of quartz sand and improving the purification efficiency. However, due to the gravity of quartz sand, it will accumulate at the bottom of the purification tube. Since the wavelength of microwaves is relatively short and the penetration is relatively weak, the quartz in the upper layer is not heated sufficiently, while the quartz sand particles at the bottom of the tube are not heated sufficiently, resulting in large fluctuations in the impurity removal rate.

[0004] Chinese Patent Application No. 202411411621.9 discloses a microwave purification device for quartz sand, including a support frame, a support plate, and a support tube mounted on the support plate via a fixed seat. It also includes a purification pipe, which has cylindrical sides and a polygonal middle section, coaxial with the support tube. With the cooperation of auxiliary mechanisms and the purification pipe, the quartz sand inside the purification pipe can be uniformly heated. The polygonal design of the middle section of the purification pipe allows for greater turbulence of the quartz sand, preventing incomplete turbulence of the quartz sand in contact with the bottom of the purification pipe and ensuring effective heating.

[0005] However, both of the aforementioned patents involve tilting the purification pipe to allow the quartz sand to fall under its own weight for discharge. At the same angle, the flow rate of quartz sand is inconsistent when there is sufficient material (in the early stage of roasting) and when there is insufficient material (in the late stage of roasting), resulting in inconsistent roasting times. Frequent adjustments to the pipe's tilt angle during the purification process can cause deviations in the residence time of quartz sand particles in the same batch inside the pipe, leading to unstable quality. Furthermore, when the purification pipe rotates the quartz sand particles, the particles may adhere to the inner wall of the purification pipe, causing uneven microwave dispersion or reflection, resulting in uneven heating of the quartz sand particles inside the pipe. Therefore, this invention proposes a quartz sand purification device and method based on microwave temperature control to solve the above problems. Summary of the Invention

The end of the vent pipe furthest from the discharge end cover is fixedly connected to the second air cylinder. The second air cylinder has a second through hole at one end, which is connected to the vent pipe. The vent pipe is provided with multiple spray holes. The discharge end cover has a discharge port for connecting to the discharge device and an air inlet that is connected to the vent pipe.

[0013] Preferably, the transmission assembly includes a roller fixedly connected to one end of the purification assembly and a motor for driving the roller to rotate. Both ends of the purification pipe are respectively fixedly connected to a rotating wheel, and the roller and the rotating wheel mesh with each other. One end of the purification assembly is fixedly connected to a motor for driving the roller to rotate, and the motor is connected to the roller in a transmission connection.

[0014] Preferably, a driving component is fixedly connected to the bottom of the purification component, and a third air cylinder is fixedly connected to one end of the driving component. One end of the third air cylinder has an air hole that communicates with the first through hole.

[0020] S5. Quartz sand particles are discharged through the discharge port.

[0021] The technical effects and advantages of this invention are as follows:

[0022] This invention utilizes the reciprocating motion of a guide vane to propel quartz sand particles into the microwave cylinder, controlling the weight of the quartz sand particles entering the purification pipe within the microwave cylinder. This ensures a consistent weight of quartz sand particles entering the microwave cylinder from the preheating cylinder, preventing inconsistent flow rates of quartz sand particles when there are sufficient or insufficient particles, which could lead to inconsistent calcination times. Furthermore, the reciprocating motion of the guide vane disperses quartz sand particles accumulated near the limiting component of the microwave cylinder through the nozzles of the second air cylinder, creating a pulsed airflow in the ventilation pipe. This disperses quartz sand particles adhering to the inner wall or blades of the purification pipe, promoting quartz sand flow while ensuring sufficient contact between the quartz sand particles and the purification gas for purification. This prevents quartz sand particles adhering to the inner wall of the pipe from affecting microwave dispersion or causing uneven reflection. Attached Figure Description

[0032] Example 1

[0033] In actual production, the flow rate of quartz sand particles during purification is inconsistent when the particles are abundant (in the early stage of roasting) and when the particles are insufficient (in the late stage of roasting), resulting in inconsistent roasting times.

[0035] Please see Figure 3 and Figure 5As shown, a limiting member 32 is provided inside the purification pipe 21. When the flow guide 31 contacts the limiting member 32, it can prevent the quartz sand particles inside the preheating cylinder from entering the microwave cylinder.

One end of the piston rod is fixedly connected to the flow guide 31, and the other end is fixedly connected to the piston plate. The piston plate can slide inside the first air cylinder 311. This is the prior art and will not be described in detail here.

[0036] Please see Figure 6 As shown, the gas delivery assembly 5 includes a second gas cylinder 51 disposed inside the purification pipe 21. A second connector 313 is fixedly connected to one end of the guide member 31 away from the first connector 312. The second connector 313 is slidably connected to the inner wall of the second gas cylinder 51. The second connector 313 consists of a piston rod and a piston plate. One end of the piston rod is fixedly connected to the guide member 31, and the other end is fixedly connected to the piston plate. The piston plate slides inside the second gas cylinder 51.

The limiting members 32 are two symmetrically distributed along the central axis of the purification pipe 21. The two limiting members 32 are fixedly connected to the second air cylinder 51 through the support rod. The end of the second air cylinder 51 near the limiting member 32 is provided with an air inlet and a spray hole. The air inlet is provided with a one-way valve, and the spray hole is a nozzle that can spray gas to blow the quartz sand particles inside the purification pipe 21. This is the prior art and will not be described in detail here.

This is existing technology and will not be described in detail here.

[0039] Please see Figure 4 and Figure 5As shown, the end of the purification pipe 21 furthest from the inlet end cover 22 is rotatably connected to the outlet end cover 23. One end of the outlet end cover 23 is fixedly connected to a ventilation pipe 52. The end of the ventilation pipe 52 furthest from the outlet end cover 23 is fixedly connected to a second air cylinder 51. One end of the second air cylinder 51 has a second through hole 53, which communicates with the ventilation pipe 52. Multiple nozzles are provided on the ventilation pipe 52, and these nozzles are evenly distributed in an array along the central axis of the ventilation pipe 52. The outlet end cover 23 has an outlet for connecting to a discharge device. The cover 23 has an air inlet that is connected to the ventilation pipe 52. The discharge device is a material cylinder that can be sealed to the discharge port and can collect the quartz sand particles inside the purification pipe 21. The ventilation pipe 52 is connected to a gas source, which is the gas required for the purification of quartz sand particles, such as chlorine, hydrogen chloride, or oxygen that can reduce the impurities inside the quartz sand particles. When using chlorine or hydrogen chloride, the discharge port and the inlet should be sealed and a gas collection device should be installed to prevent the leakage of toxic gas. This is existing technology and will not be described in detail here.

[0040] Please see Figure 1 and Figure 2 As shown, the transmission assembly 4 includes a roller 41 fixedly connected to one end of the purification assembly 2 and a motor for driving the roller 41 to rotate. The two ends of the purification pipe 21 are respectively fixedly connected to a rotating wheel 42, and the roller 41 and the rotating wheel 42 mesh with each other. One end of the purification assembly 2 is fixedly connected to a motor for driving the roller 41 to rotate. The motor is connected to the roller 41 in a transmission connection. Each rotating wheel 42 meshes with two rollers 41 respectively. The motor and the roller 41 are connected by gear transmission or belt transmission. This is the prior art and will not be described in detail here.

[0041] Please see Figure 2 and Figure 3 As shown, a driving component 24 is fixedly connected to the bottom of the purification component 2. A third air cylinder 25 is fixedly connected to one end of the driving component 24. An air hole communicating with the first through hole 314 is opened at one end of the third air cylinder 25. The driving component 24 is a hydraulic cylinder. A piston rod is connected to one end of the driving component 24. A piston plate is connected to one end of the piston rod. The piston plate slides inside the third air cylinder 25. This is prior art and will not be described in detail here.

[0042] Please see Figure 3 and Figure 4As shown, a microwave emitting device 27 is fixedly connected inside the purification component 2. The microwave emitting device 27 is sleeved outside the purification pipe 21 and rotatably connected to the purification pipe 21. One end of the base 1 is rotatably connected to the purification component 2 via a rotating shaft. Blades are provided inside the purification pipe 21. The purification component 2 is connected to a controller to control the start and stop of the motor, the heating of the microwave emitting device 27 and the heating tube 26, and the stroke of the drive component 24. The purification component 2 can be tilted by rotation, with a tilt angle of 5° to 15°. This is prior art and will not be described in detail here.

[0043] In use, first adjust the purification component 2 to the required tilt angle, start the motor to drive the purification pipe 21 to rotate, and simultaneously heat the purification pipe 21 through the microwave transmitter 27 and the heating tube 26. The quartz sand particles are fed into the preheating cylinder of the purification pipe 21 through the feeding device, and gas is introduced into the purification pipe 21 through the ventilation pipe 52. Then, start the drive component 24 to make the piston plate of the drive component 24 slide inside the third air cylinder 25, thereby generating a negative pressure inside the first air cylinder 311. The gas enters the third air cylinder 25 through the first through hole 314 and the air hole, causing the first connecting member 312 to drive the guide member 31 to move towards the feed end cover 22, pushing the quartz sand particles into the microwave cylinder for purification. By controlling the reciprocating motion of the piston plate inside the drive component 24, the guide member 31 reciprocates. When the guide member 31 moves towards the limiting member 32... When the flow guide 31 moves to contact the limiting member 32, the impact of the limiting member 32 causes the purification pipe 21 to vibrate, thereby promoting the flow of quartz sand particles inside the pipe and preventing the quartz sand from accumulating at the end of the microwave cylinder near the flow guide 31. The stroke and reciprocating speed of the drive member 24 are adjusted according to the weight of the quartz sand particles, thereby controlling the reciprocating speed of the flow guide 31. When there are enough quartz sand particles, the drive member 24 reduces the reciprocating speed to limit the quartz sand particles from entering the microwave cylinder. When there are not enough quartz sand particles, the drive member 24 increases the reciprocating speed, thereby causing the flow guide 31 to push the quartz sand particles into the microwave cylinder. This ensures that the weight of the quartz sand particles entering the microwave cylinder from the preheating cylinder is consistent, preventing inconsistent flow speeds of quartz sand particles inside the purification pipe 21 when there are not enough quartz sand particles, which would lead to inconsistent roasting times.

[0044] Example 2

[0045] In actual use, it was found that when the quartz sand passes through the purification pipe 21, it will accumulate at the end of the microwave cylinder near the limiting member 32. At the same time, when the quartz sand flows, it will adhere to the inner wall of the purification pipe 21, causing uneven microwave dispersion or reflection, resulting in uneven heating inside the quartz sand, which in turn affects the purification effect. Further improvements have been made based on the above embodiments.

[0046] In use, when the guide member 31 moves towards the limiting member 32, the gas inside the purification pipe 21 enters the second air cylinder 51. When the guide member 31 moves towards the feed end cover 22, the second connecting member 313 slides inside the second air cylinder 51, causing the gas inside the second air cylinder 51 to be ejected through the nozzle, blowing away the quartz sand particles accumulated at the end of the microwave cylinder near the limiting member 32. This prevents the quartz sand from accumulating at the end of the microwave cylinder near the limiting member 32 when passing through the purification pipe 21. Simultaneously, when the second connecting member 313 moves towards the feed end cover 22, the gas inside the second air cylinder 51 is ejected through the nozzle, dispersing the quartz sand particles accumulated at the end of the microwave cylinder near the limiting member 32. When the inside of the air cylinder 51 moves toward the limiting member 32, the gas inside the ventilation pipe 52 enters the inside of the second air cylinder 51 through the second through hole 53. When the second connector 313 moves away from the limiting member 32 inside the second air cylinder 51, the gas re-enters the inside of the ventilation pipe 52 through the second through hole 53, thereby forming a pulsed airflow at the nozzle of the ventilation pipe 52, blowing off the quartz sand particles attached to the inner wall or blades of the purification pipe 21, promoting the flow of quartz sand and allowing the quartz sand particles to fully contact the purification gas for purification.

[0047] Example 3

[0048] Based on the above embodiments, this embodiment also provides a method for using a quartz sand purification device based on microwave temperature control, including the following specific steps: S1. Start the motor to make the purification pipe 21 rotate, heat the purification pipe 21 to the working temperature, and introduce gas into the ventilation pipe 52.

[0049] S2. Quartz sand particles enter the preheating cylinder of purification pipe 21 through the feed inlet for preheating;

[0050] S3. Start the drive component 24 to drive the guide component 31 to push the quartz sand particles into the microwave cylinder for purification;

[0051] S4. The reciprocating motion of the guide component 31 creates a pulsed airflow inside the ventilation pipe 52, which blows the quartz sand particles inside the pipe to heat them evenly and allow them to react fully.

[0052] S5. Quartz sand particles are discharged through the discharge port.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
