Description

Technical Field

[0001] The present invention relates to a production and processing device for solar crucibles, and particularly to an internal slag removal device for the production of solar crucibles. Background Art

[0002] During the production and forming process of solar crucibles, especially when the solar crucible is in the forming process in the mold, part of the silicon dioxide therein will decompose and volatilize to form silicon oxide gas during high-temperature forming. At the same time, during the process of gradually decreasing temperature, the volatilized silicon oxide gas will recondense into silicon dioxide powder in the region with relatively lower temperature, which is the scum. These scums are the solid wastes in the production and forming process of solar crucibles.

[0003] During the process of removing the scum formed on the inner wall surface of the solar crucible during production, currently, there are methods such as blowing, mechanical scraping, and direct scraping after cooling. Removing the scum by mechanical scraping is to directly scrape the scum on the inner wall surface of the crucible with a scraper, but using this method will damage the inner wall surface of the crucible. And the blowing method will directly discharge the scum on the inner wall of the crucible to the external space, which not only pollutes the environment but also destroys the environmental protection of the scum as recyclable. And scraping after cooling still has damage to the inner wall of the crucible, and the removal difficulty will also increase.

[0004] In summary, the current methods for removing scum from the inner wall of solar crucibles have the disadvantages of damaging the inner wall of the crucible, lacking environmental protection, low efficiency, and slow speed.

[0005] Therefore, it is necessary to develop an internal slag removal device for the production of solar crucibles to overcome the above problems. Summary of the Invention

At the same time, it can protect the inner wall of the crucible from mechanical damage, and the process of removing the scum will not discharge high-temperature gas and gas containing impurities to the outside, improving environmental protection, and at the same time can collect the scum.

Detailed implementation manners

[0038] The following is only a preferred embodiment of the present invention, and does not limit the protection scope of the present invention accordingly.

[0039] Example 1, such as Figures 1 - 11As shown in the figure, an internal slag removal device for solar crucible production includes an electric lifting and hanging frame 1, a surrounding frame 2, an end cover 3, an upper surrounding frame 4, a lower surrounding frame 5, a contact frame 6, a propulsion mechanism 7, a posture adjustment mechanism 8, a commutation mechanism 9, a guiding mechanism 10, an exhaust mechanism 11 and a gas supply mechanism 12. The electric lifting and hanging frame 1 is an electric lifting platform controlled by a servo system, and the electric lifting and hanging frame 1 is used for lifting work. A surrounding frame 2 is fixedly connected between the moving parts of the electric lifting and hanging frame 1. The surrounding frame 2 is a horizontally placed frame structure with an inner cavity. An end cover 3 is fixedly connected to the upper side of the surrounding frame 2. The end cover 3 is used to close the upper open structure of the surrounding frame 2, so that the surrounding frame 2 has a structure with only the lower side in an open state. An upper surrounding frame 4 is fixedly connected to the upper side of the inner layer of the surrounding frame 2. Both the front and rear sides of the upper surrounding frame 4 are structures with guiding holes. A lower surrounding frame 5 is fixedly connected to the lower side of the inner layer of the surrounding frame 2. The front, rear sides and the right side wall of the lower surrounding frame 5 are all structures with a number of exhaust holes. The upper surrounding frame 4 and the lower surrounding frame 5 together form a structure that closes the inner cavity space of the surrounding frame 2, so that the inner cavity structure of the surrounding frame 2 is isolated from the outside. A contact frame 6 is fixedly connected to the lower side of the surrounding frame 2. The contact frame 6 is a heat-resistant soft rubber structure. The contact frame 6 is used to contact the upper end face of the solar crucible in the mold during the forming process, so that the space between the crucible, the contact frame 6, the upper surrounding frame 4, the lower surrounding frame 5 and the end cover 3 is isolated by the surrounding frame 2, so that the inner space of the crucible is isolated from the outside between the surrounding frame 2 and the end cover 3. A propulsion mechanism 7 is arranged in the inner cavity space on the front and rear sides of the surrounding frame 2. The propulsion mechanism 7 passes through the guiding hole structure of the upper surrounding frame 4 and spans within the surrounding space of the surrounding frame 2. A posture adjustment mechanism 8 is arranged at the position of the propulsion mechanism 7 between the surrounding frames 2. A commutation mechanism 9 is arranged on the left side of the posture adjustment mechanism 8. A guiding mechanism 10 is arranged in the commutation mechanism 9. The propulsion mechanism 7 is used to drive the posture adjustment mechanism 8, the commutation mechanism 9 and the guiding mechanism 10 to move left and right in the surrounding space of the surrounding frame 2. At the same time, the propulsion mechanism 7 can close the guiding hole structure of the upper surrounding frame 4 during operation to maintain the airtightness of the inner cavity space of the surrounding frame 2 by the upper surrounding frame 4. The posture adjustment mechanism 8 is used to drive the commutation mechanism 9 and the guiding mechanism 10 to move back and forth and up and down. The commutation mechanism 9 is used to drive the guiding mechanism 10 to rotate. An exhaust mechanism 11 is arranged at the surrounding frame 2. The exhaust mechanism 11 passes through the exhaust hole structure of the lower surrounding frame 5 and communicates with the surrounding space of the surrounding frame 2. The exhaust mechanism 11 is used to connect with an external air extraction pump, so that the exhaust mechanism 11 extracts the air in the surrounding space of the surrounding frame 2 to extract the slag-containing waste gas in the surrounding space of the surrounding frame 2. A gas supply mechanism 12 is arranged on the right side of the surrounding frame 2. The gas supply mechanism 12 is connected to the commutation mechanism 9. The gas supply mechanism 12 is used to connect with an external heating source and a plasma gas source. The gas supply mechanism 12 inputs the externally supplied heating air and plasma gas into the guiding mechanism 10. The guiding mechanism 10 is used to blow the input heating air and plasma gas to the inner wall of the solar crucible in contact with the contact frame 6.So that the guiding mechanism 10 blows off the dross adhering to the inner wall surface of the solar crucible through warm air and plasma gas; the guiding mechanism 10 can blow warm air and plasma gas to all directions of the inner wall surface of the solar crucible through the combined action of the propulsion mechanism 7, the attitude adjustment mechanism 8 and the commutation mechanism 9, so that the dross adhering to the inner wall surface of the solar crucible is blown into the enclosed space of the crucible interior, the end cover 3 and the enclosure 2. These gases containing a large amount of dross will be extracted by the exhaust mechanism 11, thus achieving the purpose of quickly removing the dross adhering to the inner wall of the solar crucible in all directions. Moreover, the process of blowing off and discharging the dross is between the end cover 3, the enclosure 2 and the crucible interior, so that the blown dross will not disperse into the external space and cause environmental impact. At the same time, due to the high-temperature operation, the high-temperature gas will not leak into the external space.,

[0040] During the production and forming process of a solar crucible, especially a solar crucible in the forming process within a mold, part of the silicon dioxide therein will decompose and volatilize at high temperature to form silicon oxide gas. At the same time, during the process of gradually decreasing temperature, the volatilized silicon oxide gas will re-condense into silicon dioxide powder in the region with relatively lower temperature, which is the dross. These drosses are the solid wastes in the production and forming process of the solar crucible. When it is necessary to remove the dross and harmlessly collect the solid wastes, that is, the dross, from the inner wall of the solar crucible during the production and forming process of the solar crucible, the internal dross removal device for solar crucible production can be used. The internal dross removal device for solar crucible production can be installed above the mold production line for solar crucible production through the electric lifting hanging frame 1, and the outer edge of the contact frame 6 is positioned directly above the solar crucible mold. Then, the heating gas source and the plasma gas source are connected to the gas supply structure, so that the gas supply structure can supply heating gas and plasma gas source to the guiding structure. Next, the exhaust mechanism 11 is connected to the external air extraction pump, gas cooler and its collection bag, so that the exhaust mechanism 11 can extract the slag-containing gas in the enclosed space surrounded by the enclosure 2, and carry out solid-gas separation on the slag-containing gas. Finally, the power circuit and control circuit of the internal dross removal device for solar crucible production are connected. When it is necessary to remove the dross on the inner wall of a solar crucible in the forming state, the mold production line for solar crucible production can be controlled to drive it to move below the contact frame 6. Subsequently, the electric lifting hanging frame 1 is controlled to move downward, so that the contact frame 6 contacts the upper edge of the solar crucible, and a closed space isolating the outside world is formed between the solar crucible, the contact frame 6, the enclosure 2 and the end cover 3. Then, the external heating gas source and plasma gas source can be controlled to be input into the guiding mechanism 10 through the gas supply mechanism 12, so that the guiding mechanism 10 sprays out high-temperature heating gas and plasma gas source to remove the dross on the inner wall of the crucible. The blown mixed gas will make the dross disperse in the formed closed space. At the same time, the external air extraction pump can be started, so that the external air extraction pump extracts the slag-containing gas in the closed space between the solar crucible, the contact frame 6, the enclosure 2 and the end cover 3 through the exhaust mechanism 11. At the same time, the propulsion mechanism 7, the posture adjustment mechanism 8 and the commutation mechanism 9 can be controlled, so that the propulsion mechanism 7, the posture adjustment mechanism 8 and the commutation mechanism 9 drive the guiding mechanism 10 to adjust its posture, so that the guiding mechanism 10 can remove the dross on the inner wall of the crucible in all directions.The guiding mechanism 10 can, through the combined action of the propulsion mechanism 7, the attitude adjustment mechanism 8, and the commutation mechanism 9, blow warm air and plasma gas onto the inner wall surface of the solar crucible in all directions, so that the dross adhering to the inner wall surface of the solar crucible is dispersed into the interior of the crucible, the enclosed space of the end cover 3 and the surrounding frame 2. These gases containing a large amount of dross will be extracted by the exhaust mechanism 11, thus achieving the purpose of quickly removing the dross adhering to the inner wall of the solar crucible in all directions. Moreover, the process of dispersing and discharging the dross is between the end cover 3, the surrounding frame 2, and the interior of the crucible, so that the blown dross will not disperse into the external space and cause environmental impact. At the same time, due to the high-temperature operation, the high-temperature gas will not leak into the external space.

[0041] Embodiment 2, as Figures 12 - 14 shown, the propulsion mechanism 7 includes an isolation frame 71, a transmission belt 72, an interconnection frame 73, and a propulsion motor 74. The number of isolation frames 71 is two groups. The isolation frames 71 are respectively fixedly connected to the front and rear side walls of the upper enclosure 4 within the inner cavity space of the surrounding frame 2. The isolation frame 71 is a directional frame structure with a hollow cavity. Transmission belts 72 are installed in the inner cavity spaces on the front and rear sides of the surrounding frame 2. The drive shafts of the transmission belts 72 are respectively rotatably installed at the upper and lower walls of the inner cavity of the surrounding frame 2. The transmission belts 72 are all integral belt types and are all high-temperature resistant structures. The opposite sides of the two transmission belts 72 are all sleeved within the hollow cavities of the adjacent isolation frames 71, so that the hollow cavity structures of the isolation frames 71 all enclose the opposite sides of the adjacent transmission belts 72, so that the transmission belts 72 can still enclose the frame structure of the isolation frame 71 when rotating. The interconnection frames 73 are slidably connected within the frame structures of the isolation frames 71. The front and rear interconnection frames 73 are fixedly connected. The interconnection frame 73 can move left and right within the frame structure of the isolation frame 71. The interconnection frame 73 is fixedly connected to the adjacent transmission belt 72 within the frame structure of the isolation frame 71. A propulsion motor 74 is installed within the inner cavity structure of the surrounding frame 2. The propulsion motor 74 is respectively connected to the drive shafts of the transmission belts 72.

[0042] Start the propulsion motor 74. The propulsion motor 74 will drive the transmission belt 72 to rotate, and then the transmission belt 72 will drive the interconnection frame 73 to move left and right. The interconnection frame 73 will drive the attitude adjustment mechanism 8, the commutation mechanism 9, and the guiding mechanism 10 to move left and right. And the transmission belt 72 will maintain the closed state of the frame structure of the isolation frame 71 during the movement, and then maintain the closed state of the guiding hole structure of the upper enclosure 4, so as to maintain the isolation state of the cavity structure of the surrounding frame 2 from the outside, so that the high-temperature gas generated during the high-temperature working process is blocked by the transmission belt 72 and will not enter the inner cavity structure of the surrounding frame 2, so as to protect the propulsion motor 74 and other control components and electronic components installed in the inner cavity of the surrounding frame 2 from being damaged by high temperature.

[0043] As Figures 15 - 16As shown in the figure, the attitude adjustment mechanism 8 includes a first electric screw rod moving pair 81, a first isolation sleeve 82, a transverse moving frame 83, a second electric screw rod moving pair 84, a second isolation sleeve 85 and a vertical moving frame 86. The first electric screw rod moving pair 81 is fixedly connected to the lower side of the interconnection frame 73. The first electric screw rod moving pair 81 has a horizontally transverse structure in the front and rear directions. The first electric screw rod moving pair 81 is a guiding pair with screw rod transmission. The screw rod part of the first electric screw rod moving pair 81 has a high-temperature resistant structure. Both the front and rear ends of the first electric screw rod moving pair 81 are fixedly connected with a first isolation sleeve 82. The driving main body of the first electric screw rod moving pair 81 is installed in the first isolation sleeve 82, so that the driving main body of the first electric screw rod moving pair 81 in the high-temperature working environment is isolated from the high temperature by the first isolation sleeve 82 to ensure the operating performance. A transverse moving frame 83 is fixedly connected to the moving part of the first electric screw rod moving pair 81. A second electric screw rod moving pair 84 is fixedly connected to the transverse moving frame 83. The second electric screw rod moving pair 84 has a vertical structure. The second electric screw rod moving pair 84 is a guiding pair with screw rod transmission. The screw rod part of the second electric screw rod moving pair 84 has a high-temperature resistant structure. Both the front and rear ends of the second electric screw rod moving pair 84 are fixedly connected with a second isolation sleeve 85. The driving main body of the second electric screw rod moving pair 84 is installed in the second isolation sleeve 85, so that the driving main body of the second electric screw rod moving pair 84 in the high-temperature working environment is isolated from the high temperature by the second isolation sleeve 85 to ensure the operating performance. A vertical moving frame 86 is fixedly connected to the moving part of the second electric screw rod moving pair 84. The commutation mechanism 9 is arranged at the vertical moving frame 86.

[0044] By controlling the operation of the first electric screw rod moving pair 81, the first electric screw rod moving pair 81 will drive its moving part to move back and forth, thereby driving the transverse moving frame 83 to move back and forth, and enabling the guiding mechanism 10 to move back and forth. By controlling the operation of the second electric screw rod moving pair 84, the second electric screw rod moving pair 84 will drive its moving part to move up and down, thereby driving the vertical moving frame 86 to move up and down, and enabling the guiding mechanism 10 to move up and down, so that the guiding mechanism 10 can perform gas injection on the upper and lower positions of the inner wall of the solar crucible.

[0045] As Figures 17 - 18As shown in the figure, the commutation mechanism 9 includes an installation cabin 91, a rotating ring 92, a commutation motor 93, a gear transmission pair 94, a first rotary joint 95 and a first hose 96. The installation cabin 91 is fixedly connected to the vertical moving frame 86. The rotating ring 92 is rotatably connected inside the installation cabin 91. The guiding mechanism 10 is arranged at the rotating ring 92. The commutation motor 93 is fixedly connected to the right side inside the installation cabin 91. A gear transmission pair 94 is connected between the output shaft of the commutation motor 93 and the rotating ring 92. The gear transmission pair 94 is a bevel gear transmission. The first rotary joint 95 is installed on the upper side inside the installation cabin 91. The lower side of the first rotary joint 95 is fixedly connected to the guiding mechanism 10. Two first hoses 96 are fixedly connected to the upper side of the first rotary joint 95. Both first hoses 96 are connected to the air supply mechanism 12. The rear first hose 96 is used for inputting warm air, and the front first hose 96 is used for inputting plasma gas. The first hose 96 is a high-temperature resistant pipeline structure. The rotating ring 92, the commutation motor 93, the gear transmission pair 94 and the first rotary joint 95 are installed inside the installation cabin 91 in a way that can reduce the influence of high temperature on the electronic components and control components therein, and avoid the failure of the rotating ring 92, the commutation motor 93, the gear transmission pair 94 and the first rotary joint 95 caused by the high-temperature working environment.

[0046] Start the commutation motor 93. The commutation motor 93 will drive the rotating ring 92 to rotate through the gear transmission pair 94, so that the rotating ring 92 drives the guiding mechanism 10 to rotate at the first rotary joint 95, enabling the guiding mechanism 10 to blow gas at all angles to the inner wall of the crucible.

[0047] As Figures 17 - 18 shown in the figure, the guiding mechanism 10 includes an extension pipe 101 and a nozzle 102. The extension pipe 101 is fixedly connected inside the rotating ring 92. The upper end of the extension pipe 101 is fixedly connected to the first rotary joint 95. The extension pipe 101 can rotate through the first rotary joint 95. The nozzle 102 is detachably installed on the lower side of the extension pipe 101. The number of nozzles 102 is not unique. The nozzles 102 respectively have a jet angle of 30 - 60 degrees obliquely downward. The obliquely downward jet angle of the nozzle 102 can make the ejected plasma gas not directly vertically jet onto the inner wall of the crucible, avoiding damage to the inner wall surface of the crucible caused by the vertical impact of the high-temperature plasma gas.

[0048] The warm air and plasma gas source transported from the air supply mechanism 12 will be obliquely downward jetted to the surface of the inner wall of the crucible through the obliquely downward structure of the nozzle 102, so that the dross on the surface of the inner wall of the crucible is blown off by the gas, and at the same time, the temperature of the inner wall of the crucible is maintained, avoiding excessive temperature loss due to the dross removal process. The obliquely downward jetting method can make the warm air and plasma gas flow downward along the impact direction after blowing off the dross on the surface of the inner wall of the crucible, avoiding a large vertical impact force on the surface of the inner wall of the crucible.

[0049] As Figures 6 - 8As shown, the exhaust mechanism 11 includes an exhaust pipe 111, a main pipe 112, and an air extraction end 113. The exhaust pipe 111 is respectively installed in the exhaust hole structure of the lower support frame 5. The exhaust pipe 111 is a hollow pipe structure, and the exhaust pipe 111 communicates with the enclosed space of the enclosure frame 2. The main pipes 112 are fixedly connected between the opposite sides of the exhaust pipe 111. The main pipes 112 are in a communicating state on the right side. The right ends of the main pipes 112 are fixedly connected with air extraction ends 113, and the air extraction ends 113 are connected to an external air extraction pump.

[0050] Connect the air extraction end 113 to an external air extraction pump, a gas cooler, and a dust collection bag. Turn on the external air extraction pump. The air extraction pump will extract the slag-containing gas in the enclosed space formed between the solar crucible, the contact frame 6, the enclosure frame 2, and the end cover 3 through the main pipe 112 and the exhaust pipe 111, and cool it through the gas cooler. Then, collect the solid floating slag through the dust collection bag for subsequent reprocessing. By using this method, the guiding mechanism 10 can remove slag inside the crucible while quickly sucking out the slag-containing gas, balance the air pressure in the formed enclosed space, and avoid the harm caused by the direct discharge of the slag-containing gas to the outside.

[0051] As Figure 6 and Figure 16 、 Figure 17 and Figure 18 As shown, the gas supply mechanism 12 includes a placement sleeve 121, a corrugated hose 122, a gas supply end 123, and a second hose 124. Two groups of placement sleeves 121 are fixedly connected to the right side of the enclosure frame 2. The placement sleeve 121 is a pipe structure that is open to the enclosed space of the enclosure frame 2 from the left side. The right side walls inside the placement sleeve 121 are fixedly connected with corrugated hoses 122. The corrugated hoses 122 are all heat-resistant elastic retractable structures. The right sides of the placement sleeves 121 are fixedly connected with gas supply ends 123. The gas supply ends 123 are respectively connected to the right ends of the adjacent corrugated hoses 122 and are in communication. The rear gas supply end 123 is connected to an external heating source, and the front gas supply end 123 is connected to an external plasma gas source. The left ends of the corrugated hoses 122 are fixedly connected with second hoses 124, and the second hoses 124 are respectively connected to the adjacent first hoses 96.

[0052] Connect the front gas supply end 123 to an external plasma gas source, and at the same time connect the rear gas supply end 123 to an external heating source. Turn on the external heating source and the plasma gas source, so that a certain proportion of the heating source and the plasma gas source are jointly input to the nozzle 102 for spraying, so that the heating gas and the plasma gas impact the inner wall of the crucible to remove slag.

[0053] As Figure 2 、 Figure 4 and Figure 19As shown in the figure, it further includes a air supply mechanism 13. The air supply mechanism 13 includes an installation pipe 131, an electric slide rail 132, an air supply pipe 133, an air supply hose 134, an air supply end 135 and a diffusion assembly 14. The air supply mechanism 13 is arranged on the upper side of the end cover 3. The air supply mechanism 13 is used to quickly blow a large amount of warm air into the enclosed space in the enclosure 2, and at the same time improve the air extraction power of the exhaust mechanism 11, so as to quickly remove the remaining floating scum in the enclosed space in the enclosure 2, and prevent the scum from adhering to the inner wall of the crucible again. The upper side of the end cover 3 is fixedly connected with an installation pipe 131. The installation pipe 131 is a pipe structure open at the lower side. Electric slide rails 132 are fixedly connected to both the left and right side walls in the installation pipe 131. The electric slide rail 132 is a vertically arranged track pair controlled by a servo system. An air supply pipe 133 is fixedly connected between the moving parts of the electric slide rail 132. The air supply pipe 133 is located at the lower side in the installation pipe 131 and is connected in a sliding and sealing manner. The air supply pipe 133 is a heat-resistant hollow pipe structure. The upper end of the air supply pipe 133 is fixedly connected with an air supply hose 134. The upper side of the installation pipe 131 is fixedly connected with an air supply end 135. The air supply end 135 is used to connect with an external warm air source. The lower end of the air supply pipe 133 is fixedly connected with a diffusion assembly 14. The diffusion assembly 14 is used to output the input warm air in the crucible by high-pressure jetting.

[0054] After the slag removal of the inner wall of the crucible is completed by the guiding mechanism 10, the electric slide rail 132 can be started, so that the electric slide rail 132 drives the air supply pipe 133 to move downward through its moving parts, and the air supply pipe 133 drives the diffusion assembly 14 into the crucible. At this time, the external warm air source can be started to input a large amount of warm air into the air supply pipe 133, and at the same time, the air extraction power of the exhaust mechanism 11 is improved. A large amount of warm air input from the air supply pipe 133 will be quickly ejected through the diffusion assembly 14, causing the diffusion assembly 14 to rotate in the crucible to accelerate the movement of the floating scum in the crucible, thereby increasing the speed at which these scum are extracted by the exhaust mechanism 11, so as to quickly remove the remaining floating scum in the enclosed space in the enclosure 2 and prevent the scum from adhering to the inner wall of the crucible again. <A

[0055] As Figure 19 shown in the figure, the diffusion assembly 14 includes a second rotary joint 141, a transverse deflection air duct 142 and an eccentric deflection air duct 143. The second rotary joint 141 is fixedly connected to the lower end of the air supply pipe 133. The second rotary joint 141 is a heat-resistant ceramic bearing structure. Transverse deflection air ducts 142 are fixedly connected to the front and rear positions on the lower side of the rotating part of the second rotary joint 141. Eccentric deflection air ducts 143 are fixedly connected to the left and right positions on the lower side of the rotating part of the second rotary joint 141. The inclination angles of the transverse deflection air duct 142 and the eccentric deflection air duct 143 are both set in the clockwise direction.

[0056] A large amount of warm air passing through the air supply duct 133 will be quickly discharged from the lateral deflection air duct 142 and the eccentric deflection air duct 143 to accelerate the movement of the floating dross in the crucible. At the same time, the lateral deflection air duct 142 and the eccentric deflection air duct 143 are pushed by the air flow to rotate counterclockwise, so that the lateral deflection air duct 142 and the eccentric deflection air duct 143 conduct all-round high-temperature gas transportation inside the crucible.

[0057] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
