DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

[0040] See also Figure 1-9 The present invention provides a technical solution: a quartz sand microwave purification device, comprising a support frame 1, a support plate 2, and a support tube 31 installed on the support plate 2 through a fixing seat 30, and also comprising:

[0041] Purification pipeline 4, the two sides of the purification pipeline 4 are cylindrical, the middle part is polygonal, coaxial with the support pipe 31, and the support pipe 31 is penetrated, and the purification pipeline 4 is sleeved with a wave baffle 41, which is located at both ends of the middle polygonal part of the purification pipeline 4 and is fixed to the inner wall of the support pipe 31;

[0042] A closed cover 44, wherein the closed cover 44 is sleeved on the purification pipeline 4;

[0043] A microwave generator 5, wherein there are a plurality of microwave generators 5 and the microwave generators 5 are evenly distributed in the middle part of the closed cover 44. A waveguide is provided on each of the microwave generators 5. The waveguide penetrates the closed cover 44 and the outlets thereof correspond to the surface of the purification pipeline 4. The microwave generator 5 heats the middle part of the purification pipeline 4;

[0044] The wave baffle 41 is made of metal, which can effectively prevent the microwaves generated by the microwave generator 5 from causing damage to other components in the support tube 31;

[0045] A collar 61, wherein the collar 61 is sleeved on the inlet end of the purification pipeline 4, and a collar 2 62 is sleeved on the outlet end of the purification pipeline 4;

[0046] A first docking cover 7, which is mounted on the collar 1 61 and is connected to the support plate 2 by a first fixing rod 72. The first docking cover 7 is connected to a metal hose 71, which is externally connected to a vacuum extraction system;

[0047] The vacuum environment has a significant effect on the purification of quartz sand, which can not only promote the explosion of gas-liquid inclusions and the removal of hydroxyl groups, but also promote the diffusion and removal of impurities, improve the purification efficiency and reduce the difficulty of subsequent treatment;

[0048] A feeding mechanism 9, which is mounted on the first docking cover 7 and is used to guide the quartz sand to be purified to fall into the first docking cover 7;

[0049] A second docking cover 8, which is mounted on the second sleeve ring 62 and is connected to the support plate 2 by a second fixing rod 81;

[0050] The first fixing rod 72 and the second fixing rod 81 respectively limit the positions of the first docking cover 7 and the second docking cover 8, so that when the subsequent purification pipeline 4 rotates, these parts will not rotate accordingly;

[0051] The discharging mechanism 10 is installed on the second docking cover 8 and is used to guide the purified quartz sand to be discharged from the equipment. In cooperation with the feeding mechanism 9, the purification pipeline 4 is always in a vacuum state.

[0052] Auxiliary mechanism 11, the auxiliary mechanism 11 is installed on the purification pipeline 4 and connected to the support plate 2. The auxiliary mechanism 11 and the purification pipeline 4 drive the quartz sand to be continuously turned over during the purification process to avoid the accumulation of quartz sand, thereby preventing the uneven heating caused by high heat at the bottom and low heat at the top;

[0053] The adjustment mechanism 12 is installed on the support frame 1 and connected to the support plate 2. The adjustment mechanism 12 adjusts the angle between the support plate 2 and the surface of the support frame 1, thereby changing the angle between the purification pipe 4 on the support plate 2 and the ground, thereby changing the sliding speed of the quartz sand in the purification pipe 4.

[0054] like Figure 6 As shown, the middle part of the purification pipe 4 is sleeved with a dielectric ceramic 42 , which is a polygonal cylinder and fits the middle part of the purification pipe 4 .

[0055] The microwave generators 5 are arranged in a circular array on the surface of the closed cover 44, and the outlets of the corresponding waveguide tubes are in contact with the planes of the polygonal part of the purification pipe 4. When microwaves are generated, the planes and edges help to evenly distribute the microwaves when they are reflected in the purification pipe 4, which solves the problem in the prior art that the arc-surface purification pipe causes uneven microwave divergence or reflection, resulting in uneven heating, thereby affecting the purification effect. At the same time, the inner wall of the traditional purification pipe is smooth, which is not conducive to the turning over of the internal quartz sand when the purification pipe rotates. The quartz sand at the bottom will be in contact with the bottom surface of the inner wall of the purification pipe for a long time, further causing uneven heating. However, when the polygonal surface of the middle part of the purification pipe 4 in the present invention drives the quartz sand inside to turn over, the quartz sand is easier to turn over, the turning amplitude is larger, and it is conducive to the divergence and reflection of microwaves.

[0056] like Figure 5 , 7 As shown, an electric heating tube 43 is sleeved on the purification pipeline 4, and the electric heating tube 43 is located at the entrance of the purification pipeline 4. The sealed cover 44 surrounds the electric heating tube 43 and is fixedly connected to the electric heating tube 43. The sealed cover 44 is fixed to the inner wall of the support tube 31. The electric heating tube 43 and the sealed cover 44 are both rotatably connected to the purification pipeline 4. When the purification pipeline 4 rotates, the electric heating tube 43 and the sealed cover 44 will not be driven to rotate synchronously, thereby reducing the driving force required to drive the purification pipeline 4 to rotate. A high-temperature resistant heat-insulating material 45 is arranged in the sealed cover 44. In the sealed cover 44, the space between the two wave-baffle plates 41 is also provided with a high-temperature resistant heat-insulating material 45. The high-temperature resistant heat-insulating material 45 is preferably made of quartz wool. A first clamping ring 46 is fixed on one side of the sealed cover 44, and a first annular groove 47 is provided near the first clamping ring 46. One side of the ring 61 is engaged with the first annular groove 47 to form an anti-flow structure to prevent microwave leakage.

[0057] like Figure 6 , 8 As shown, a slow cooling hood 48 is sleeved on the purification pipeline 4, and the slow cooling hood 48 is fixed on the inner wall of the support tube 31 and is rotatably connected to the purification pipeline 4. A water cooling hood 49 is sleeved on the purification pipeline 4, and the water cooling hood 49 is located at the outlet of the purification pipeline 4, and the water cooling hood 49 and the purification pipeline 4 are rotatably connected. The two sides of the water cooling hood 49 are respectively connected to a water inlet pipe 491 and a water outlet pipe 492, and the water inlet pipe 491 and the water outlet pipe 492 are connected to an external water circulation system. A second clamping ring 410 is fixed on one side of the water cooling hood 49, and a second annular groove 411 is opened on the second clamping ring 410, and one side of the ring 62 is engaged with the second annular groove 411 to form an anti-flow structure to prevent microwave leakage.

[0058] like Figure 8 As shown, an annular turntable 80 is provided on the first docking cover 7 and the second docking cover 8, and an annular slide rail 82 is provided on one side of the ring 1 61 and the ring 2 62. The annular turntable 80 on the first docking cover 7 and the second docking cover 8 respectively fits with the annular slide rail 82 on the ring 1 61 and the ring 2 62, and a sealing plate 83 is provided on the ring 1 61 and the ring 2 62. The sealing plate 83 is fixed to the first docking cover 7 and the second docking cover 8 by bolts, and an annular box 85 with a magnetic fluid 84 sealed inside is sleeved on the outer periphery of the first docking cover 7 and the second docking cover 8.

[0059] When the purification pipeline 4 rotates, the annular turntable 80 can reduce the friction between it and its own connecting parts, so that the purification pipeline 4 can rotate more smoothly. An anti-flow structure is formed between the ring 1 61 and the ring 2 62 and their corresponding sealing plates 83, which cooperates with the magnetic fluid 84 wrapped around the outside of the ring 1 61 and the ring 2 62 to effectively prevent microwaves from leaking from the connection.

[0060] like Figure 4 As shown, an air inlet pipe 86 is provided on one side of the second docking cover 8, and hydrogen chloride gas is continuously injected into the air inlet pipe 86. A one-way valve 861 is provided in the air inlet pipe 86, and the one-way valve 861 limits the external gas from entering the purification pipeline 4 through the air inlet pipe 86, and the material in the purification pipeline 4 cannot be discharged through the air inlet pipe 86.

[0061] Quartz sand often contains metal impurities such as iron, aluminum, calcium, and magnesium. The presence of these impurities will seriously affect the purity of the quartz sand. Hydrogen chloride gas has strong reducing properties and certain complexing abilities at high temperatures, and can react chemically with these metal impurities to generate volatile or soluble metal chlorides. These metal chlorides can be more easily removed in subsequent treatment processes such as heating and washing, thereby improving the purity of the quartz sand. High-temperature treatment with hydrogen chloride gas can accelerate the removal of impurities and shorten the purification time; at the same time, hydrogen chloride gas can also be used as a protective gas to prevent quartz sand from being oxidized at high temperatures or reacting unnecessarily with other gases. The one-way valve 861 can prevent quartz sand from entering the air inlet pipe 86 and causing damage to the equipment.

[0062] like Figure 7 As shown, the feeding mechanism 9 includes a feed pipe 91 which is installed through the first docking cover 7. The feed pipe 91 is inclined, one end of which is located inside the first docking cover 7, and the other end is connected to a feed transition bin 92. The feed transition bin 92 is connected to a feed hopper 93. A first valve 94 is arranged between the feed hopper 93 and the feed transition bin 92, and a second valve 95 is arranged between the feed transition bin 92 and the feed pipe 91.

[0063] like Figure 4 As shown, the discharging mechanism 10 includes a discharging hopper 101 connected to the bottom of the second docking cover 8, the discharging hopper 101 is connected to a discharging transition bin 102, a third valve 103 is installed between the discharging hopper 101 and the discharging transition bin 102, and a fourth valve 104 is arranged at the bottom of the discharging transition bin 102.

[0064] The staff adds quartz sand to the feed hopper 93 through the material transport mechanism. The opening and closing states of the first valve 94 and the second valve 95 are opposite, that is, when the first valve 94 is opened, the second valve 95 is closed, and when the first valve 94 is closed, the second valve 95 is opened. The third valve 103 and the fourth valve 104 are similar. When the first valve 94 is opened, the quartz sand in the feed hopper 93 enters the feed transition bin 92 through the first valve 94. Then the first valve 94 is closed and the second valve 95 is opened. The quartz sand in the feed transition bin 92 falls into the sleeve ring 61 through the feed pipe 91 for subsequent purification. The discharging mechanism 10 is similar. The third valve 103 and the fourth valve 104 also have only one valve opened and the other valve closed. In conjunction with the vacuum extraction system connected to the metal hose 71, the purification pipeline 4 is always in a vacuum state, which greatly improves the quality of the purified quartz sand.

[0065] like Figure 1 , 6 , as shown in 8, Figure 1 The fixing ring 111 and the supporting ring 118 are complete rings. Figure 6 , 8The fixing ring 111 and the supporting ring 118 are schematic cross-section diagrams, and the auxiliary mechanism 11 includes a fixing ring 111 sleeved on the ring 1 61 and the ring 2 62, and a slide groove 112 is provided on the fixing ring 111. A double-output shaft motor 113 is installed at the bottom of the support plate 2, and pulleys 114 are installed at both ends of the double-output shaft motor 113. Belts 115 are connected between the pulleys 114 and the slide grooves 112. It also includes a bracket 116 relatively installed on the support plate 2, and a supporting wheel 117 is provided on the bracket 116. There are multiple supporting wheels 117, which are distributed in a ring shape. A supporting ring 118 is sleeved on the purification pipeline 4, and the supporting wheels 117 support the bottom of the supporting ring 118.

[0066] The double-output shaft motor 113 is turned on. The double-output shaft motor 113 drives the fixed ring 111 to rotate through the pulley 114 and the belt 115. The fixed ring 111 drives the purification pipe 4 to rotate through the ring 1 61 and the ring 2 62. The quartz sand inside the purification pipe 4 is turned over by the rotation of the purification pipe 4, so that the quartz sand is heated more evenly during the heating process. In order for the belt 115 to be transmitted smoothly, the belt 115 is in a taut state, that is, the two ends of the purification pipe 4 are always subjected to the downward pulling force from the belt 115, and the friction force of the purification pipe 4 during rotation will increase. The cooperation of the support wheel 117 and the support ring 118 limits the position of the purification pipe 4. The support wheel 117 also reduces this part of the friction force, and the equipment operates more smoothly.

[0067] like Figure 3 , 4 As shown, the adjustment mechanism 12 includes a first fixed plate 121 relatively arranged on one side of the bottom surface of the support plate 2, a second fixed plate 122 is relatively arranged on the side of the top of the support frame 1 corresponding to the first fixed plate 121, a first rotating shaft 123 is installed through the connection between the first fixed plate 121 and the second fixed plate 122, a third fixed plate 124 is relatively installed on the other side of the bottom surface of the support plate 2, a fourth fixed plate 125 is relatively arranged on the side of the top of the support frame 1 corresponding to the third fixed plate 124, a second rotating shaft 126 is installed through the third fixed plate 124, a third rotating shaft 127 is installed through the fourth fixed plate 125, a hydraulic rod 128 is fixed on the third rotating shaft 127, the bottom end of the hydraulic rod 128 is fixed to the third rotating shaft 127, and the top end is fixed to the second rotating shaft 126.

[0068] Ordinary natural quartz ore is affected by magma movement and geological conditions, and its impurity content and distribution, fluid inclusion type and chemical elements vary. The quality of quartz ore in different regions or even in the same region is not uniform, which leads to the need to select the appropriate heating time according to the quality of the quartz sand itself.

[0069] The staff turns on the hydraulic rod 128, and through the extension or shortening of the hydraulic rod 128, the support plate 2 is driven to rotate around the first rotation axis 123 as the center through the second rotation axis 126 and the third fixed plate 124, so as to adjust the angle between the support plate 2 and the support frame 1. After the angle of the support plate 2 changes, the purification pipe 4 is driven to change the angle accordingly through the fixed seat 30, the support tube 31 and the support tube 31 connecting parts. The gravitational potential energy of the quartz sand in the purification pipe 4 will change, and the time required for the quartz sand to pass through the purification pipe 4 will change accordingly, thereby achieving the purpose of controlling the heating time of the quartz sand.

[0070] The working principle is as follows: after the staff rotates the purification pipeline 4 to a suitable angle through the adjustment mechanism 12, the double-output shaft motor 113, the microwave generator 5 and the electric heating tube 43 are turned on, and at the same time, the vacuum extraction system extracts the purification pipeline 4 into a vacuum state, and at the same time, hydrogen chloride gas is continuously injected into the intake pipe 86. Then, the staff continuously adds quartz sand to the feed hopper 93. The opening and closing states of the first valve 94 and the second valve 95 are opposite, that is, when the first valve 94 is opened, the second valve 95 is closed, and when the first valve 94 is closed, the second valve 95 is opened. The third valve 103 and the fourth valve 104 are similarly opened. When the first valve 94 is opened, the quartz sand in the feed hopper 93 enters the feed transition bin 92 through the first valve 94. Then the first valve 94 is closed and the second valve 95 is opened. The quartz sand in the feed transition bin 92 falls into the sleeve ring 1 61 through the feed pipe 91. The discharging mechanism 10 is similarly opened. The purified quartz sand is discharged from the equipment through the discharging transition bin 102 and the fourth valve 104. That is, the purification pipeline 4 is always in a vacuum state, which greatly improves the quality of the purified quartz sand.

[0071] Since the purification pipeline 4 is inclined under the action of the adjustment mechanism 12, the quartz sand in the sleeve ring 61 slides toward the outlet of the purification pipeline 4 under the action of its own gravity, and is turned over synchronously during the sliding process under the action of the auxiliary mechanism 11. It will first be preheated by the electric heating tube 43. The high-temperature resistant insulation material 45 can effectively maintain the temperature of this part to prevent the heat energy generated by the electric heating tube 43 from being lost quickly. After being preheated by the electric heating tube 43, it enters the microwave generator 5. The microwave generator 5 generates Microwaves act on the dielectric ceramic 42 and the purification pipeline 4. The dielectric ceramic 42 can both homogenize the microwaves and assist in heating. This section of the purification pipeline 4 is a polygonal cylinder, which can increase the amplitude of the quartz sand flipping. At this time, the quartz sand is in a high-temperature vacuum state and is greatly flipped and reacts with the hydrogen chloride gas. The quality of purification is greatly improved.
