Description

Technical Field

[0001] The invention relates to solar crucible production and processing equipment, in particular to an internal slag removal device for solar crucible production. Background Art

[0002] During the production and molding process of solar crucibles, especially when the solar crucible is in the molding process in the mold, the silicon dioxide therein will partially decompose and volatilize during the high-temperature molding to form silicon oxide gas. At the same time, as the temperature is gradually lowered, the volatilized silicon oxide gas will re-condense into silicon dioxide powder in the relatively low temperature area, which is scum. These scums are the solid waste in the production and molding process of solar crucibles.

[0003] In the process of removing scum formed on the inner wall surface of the solar crucible during the production process, there are currently three methods: blowing, mechanical scraping, and direct scraping after cooling. The mechanical scraping method uses a scraper to directly scrape the scum on the inner wall surface of the crucible, but this method will damage the inner wall surface of the crucible; the blowing method will directly discharge the scum on the inner wall of the crucible into the external space, which not only pollutes the environment but also destroys the environmental protection of the scum as it can be recycled. Scraping after cooling still damages the inner wall of the crucible and increases the difficulty of removal.

[0004] In summary, the current method of removing scum from the inner wall of the solar crucible has the disadvantages of damaging the inner wall of the crucible, being environmentally unfriendly, and having low efficiency and slow speed.

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

DETAILED DESCRIPTION

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

[0039] Example 1, as Figures 1-11As shown, an internal slag removal device for solar crucible production includes an electric lifting hanger 1, an enclosing frame 2, an end cover 3, an upper bag frame 4, a lower bag frame 5, a contact frame 6, a propulsion mechanism 7, a posture adjustment mechanism 8, a reversing mechanism 9, a guide mechanism 10, an exhaust mechanism 11 and an air supply mechanism 12. The electric lifting hanger 1 is an electric lifting platform controlled by a servo system. The electric lifting hanger 1 is used for lifting and lowering. The enclosing frame 2 is fixedly connected between the moving parts of the electric lifting hanger 1. The enclosing frame 2 is a horizontal frame structure with an inner cavity. The end cover 3 is fixedly connected to the upper side of the enclosing frame 2. The end cover 3 is used to close the upper open structure of the enclosing frame 2, so that the enclosing frame 2 is a structure in which only the lower side is in an open state. The inner layer of the enclosing frame 2 The side is fixedly connected with an upper packaging frame 4, and the front and rear sides of the upper packaging frame 4 are structures with guide holes. The lower side of the inner layer of the surrounding frame 2 is fixedly connected with a lower packaging frame 5, and the front and rear sides and the right side wall of the lower packaging frame 5 are structures with a number of exhaust holes. The upper packaging frame 4 and the lower packaging 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 world. The lower side of the surrounding frame 2 is fixedly connected with a contact frame 6, and the contact frame 6 is a high-temperature resistant soft rubber structure. The contact frame 6 is used to contact the upper end face of the solar crucible that is in the mold and in the forming process, so that the space between the crucible, the contact frame 6, the upper packaging frame 4, the lower packaging frame 5 and the end cover 3 is isolated by the surrounding frame 2, so that the internal space of the crucible is between the surrounding frame 2 and the end cover 3 and isolated from the outside world. A propulsion mechanism 7 is provided in the inner cavity space on the front and rear sides of the frame 2. The propulsion mechanism 7 passes through the guide hole structure of the upper package frame 4 and spans the enclosed space of the enclosed frame 2. A posture adjustment mechanism 8 is provided at the position between the enclosed frames 2. A reversing mechanism 9 is provided on the left side of the posture adjustment mechanism 8. A guiding mechanism 10 is provided in the reversing mechanism 9. The propulsion mechanism 7 is used to drive the posture adjustment mechanism 8, the reversing mechanism 9 and the guiding mechanism 10 to move left and right in the enclosed space of the enclosed frame 2. At the same time, the propulsion mechanism 7 can close the guide hole structure of the upper package frame 4 during operation to maintain the sealing of the upper package frame 4 to the inner cavity space of the enclosed frame 2. The posture adjustment mechanism 8 is used to drive the reversing mechanism 9 and the guiding mechanism 10 to move back and forth and up and down. The reversing mechanism 9 is used to drive the guiding mechanism 10 The guide mechanism 10 rotates, and an exhaust mechanism 11 is provided at the surrounding frame 2. The exhaust mechanism 11 passes through the exhaust hole structure of the lower package frame 5 and communicates with the surrounding space of the surrounding frame 2. The exhaust mechanism 11 is used to connect with an external vacuum pump so that the exhaust mechanism 11 can exhaust the surrounding space of the surrounding frame 2 to extract the slag-containing waste gas in the surrounding space of the surrounding frame 2. An air supply mechanism 12 is provided on the right side of the surrounding frame 2. The air supply mechanism 12 is connected to the reversing mechanism 9. The air supply mechanism 12 is used to connect with an external heating source and a plasma gas source. The air supply mechanism 12 inputs the external heating and plasma gas into the guide mechanism 10. The guide mechanism 10 is used to blow the input heating and plasma gas toward the inner wall of the solar crucible in contact with the contact frame 6.The guide mechanism 10 uses heat and plasma gas to blow away the scum adhering to the inner wall surface of the solar crucible. The guide mechanism 10 can blow heat and plasma gas to the inner wall surface of the solar crucible in all directions through the cooperation of the propulsion mechanism 7, the posture adjustment mechanism 8 and the reversing mechanism 9, so that the scum adhering to the inner wall surface of the solar crucible is blown away into the crucible interior, the end cover 3 and the surrounding space of the surrounding frame 2. These gases containing a large amount of scum will be extracted by the exhaust mechanism 11, thus achieving the purpose of all-round and rapid removal of scum adhering to the inner wall of the solar crucible. The process of blowing away and discharging scum occurs between the end cover 3, the surrounding frame 2 and the crucible interior, so that the blown scum will not float in 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 molding process of the solar crucible, especially during the molding process of the solar crucible in the mold, the silicon dioxide therein will be partially decomposed and volatilized to form silicon oxide gas during the high-temperature molding. At the same time, in the process of gradually lowering the temperature, the volatilized silicon oxide gas will re-condense into silicon dioxide powder in the relatively low temperature area, which is scum. The scum is the solid waste in the production and molding process of the solar crucible. When it is necessary to remove the solid waste, i.e., scum, from the inner wall of the solar crucible and collect it harmlessly, the solar crucible can be used. An internal slag removal device for producing solar crucibles; the internal slag removal device for producing solar crucibles can be installed above the mold assembly line for producing solar crucibles through an electric lifting hanger 1, and the outer edge of the contact frame 6 is located just above the solar crucible mold, and the heating source and the plasma gas source are connected to the gas supply structure so that the gas supply structure can supply heating and plasma gas sources to the guide structure, and then the exhaust mechanism 11 is connected to the external vacuum pump and gas cooler and its collection bag so that the exhaust mechanism 11 can extract the slag-containing gas in the space surrounded by the surrounding frame 2 and perform solid-gas separation on the slag-containing gas. The solar crucible is separated from the surrounding frame 2, and finally the power circuit and control circuit of the internal slag removal device for the production of the solar crucible are connected; when it is necessary to remove the slag on the inner wall of a solar crucible in a forming state, the mold assembly line for producing the solar crucible can be controlled to drive it to the bottom of the contact frame 6, and then the electric lifting hanger 1 is controlled to move downward so that the contact frame 6 contacts the upper edge of the solar crucible, so that a closed space is formed between the solar crucible, the contact frame 6, the surrounding frame 2 and the end cover 3 to isolate the outside world; then the external heating source and plasma gas source can be controlled to be input into the guide mechanism 10 through the gas supply mechanism 12, so that the guide mechanism 10 The guide mechanism 10 ejects high temperature warm air and plasma gas source to remove scum from the inner wall of the crucible, and the blown mixed gas will cause the scum to float in the formed enclosed space. At the same time, the external vacuum pump can be turned on to allow the external vacuum pump to extract the slag-containing gas in the enclosed space between the solar crucible, the contact frame 6, the surrounding frame 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 reversing mechanism 9 can be controlled to drive the propulsion mechanism 7, the posture adjustment mechanism 8 and the reversing mechanism 9 to drive the guide mechanism 10 to adjust its posture, so that the guide mechanism 10 can remove scum from the inner wall of the crucible in all directions.The guide mechanism 10, through the coordinated efforts of the propulsion mechanism 7, the posture adjustment mechanism 8, and the reversing mechanism 9, omnidirectionally blows warm air and plasma gas onto the inner surface of the solar crucible, dispersing any scum adhering to the inner surface into the crucible interior and the space enclosed by the end cap 3 and the surrounding frame 2. This scum-laden gas is then extracted by the exhaust mechanism 11, thus achieving the goal of rapidly and comprehensively removing scum adhering to the inner surface of the solar crucible. Furthermore, the scum dispersal and discharge process occurs between the end cap 3, the surrounding frame 2, and the crucible interior, preventing the blown scum from dispersing into the external space and causing environmental impact. Furthermore, due to the high-temperature operation, the high-temperature gas is also prevented from leaking into the external space.

[0041] Example 2, as Figure 12-14 As shown, the propulsion mechanism 7 includes an isolation frame 71, a transmission belt 72, an interconnection frame 73 and a propulsion motor 74. There are two groups of isolation frames 71. The isolation frames 71 are fixedly connected to the front and rear side walls of the upper package frame 4 and are located in the inner cavity space of the surrounding frame 2. The isolation frame 71 is a directional frame structure with a hollow cavity. The inner cavity spaces on the front and rear sides of the surrounding frame 2 are both equipped with transmission belts 72. The driving shafts of the transmission belts 72 are rotatably installed on the upper and lower walls of the inner cavity of the surrounding frame 2. The transmission belts 72 are all integral belts and are high-temperature resistant structures. The opposite sides of the transmission belts 72 on both sides are both fitted on the adjacent isolation frames 71. In the hollow cavity, the hollow cavity structure of the isolation frame 71 surrounds the opposite side of the adjacent transmission belt 72, so that the transmission belt 72 can still close the frame structure of the isolation frame 71 when rotating. The frame structure of the isolation frame 71 is slidably connected with the interconnecting frame 73, and the front and rear interconnecting frames 73 are fixedly connected. The interconnecting frame 73 can move left and right in the frame structure of the isolation frame 71. The interconnecting frame 73 is fixedly connected to the adjacent transmission belt 72 in the frame structure of the isolation frame 71. A propulsion motor 74 is installed in the inner cavity structure of the enclosing frame 2, and the propulsion motor 74 is respectively connected to the drive shaft of the transmission belt 72.

[0042] Start the propulsion motor 74, which 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 reversing mechanism 9 and the guide mechanism 10 to move left and right. 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 guide hole structure of the upper package frame 4, thereby maintaining the isolation state of the cavity structure of the enclosure frame 2 from the outside world, so that the high-temperature gas generated during the high-temperature working process will be blocked by the transmission belt 72 and will not enter the inner cavity structure of the enclosure frame 2, so as to protect the propulsion motor 74 and other control components and electronic components installed in the inner cavity of the enclosure frame 2 from high-temperature failure.

[0043] like Figure 15-16As shown, the posture adjustment mechanism 8 includes a first electric screw moving pair 81, a first isolation sleeve 82, a transverse frame 83, a second electric screw moving pair 84, a second isolation sleeve 85 and a vertical moving frame 86. The first electric screw moving pair 81 is fixedly connected to the lower side of the interconnected frame 73. The first electric screw moving pair 81 is a front-to-back horizontal structure. The first electric screw moving pair 81 is a screw-driven guide pair. The screw parts of the first electric screw moving pair 81 are high-temperature resistant structures. The front and rear ends of the first electric screw moving pair 81 are fixedly connected with the first isolation sleeve 82. The driving host of the first electric screw moving pair 81 is installed in the first isolation sleeve 82, so that the driving host of the first electric screw moving pair 81 in a high-temperature working environment is isolated from the high temperature by the first isolation sleeve 82 to ensure the operating performance. The moving part of an electric screw moving pair 81 is fixedly connected to a transverse frame 83, and the transverse frame 83 is fixedly connected to a second electric screw moving pair 84. The second electric screw moving pair 84 is a vertical structure, and the second electric screw moving pair 84 is a screw-driven guide pair. The screw parts of the second electric screw moving pair 84 are high-temperature resistant structures. The front and rear ends of the second electric screw moving pair 84 are fixedly connected to a second isolation sleeve 85. The driving main unit of the second electric screw moving pair 84 is installed in the second isolation sleeve 85, so that the driving main unit of the second electric screw moving pair 84 in a high-temperature working environment is isolated from the high temperature by the second isolation sleeve 85 to ensure the operating performance. The moving part of the second electric screw moving pair 84 is fixedly connected to a vertical moving frame 86, and the reversing mechanism 9 is arranged at the vertical moving frame 86.

[0044] Control the operation of the first electric screw moving pair 81, the first electric screw moving pair 81 will drive its moving parts to move forward and backward, thereby driving the transverse moving frame 83 to move forward and backward, and causing the guide mechanism 10 to move forward and backward. Control the operation of the second electric screw moving pair 84, the second electric screw moving pair 84 will drive its moving parts to move up and down, thereby driving the vertical moving frame 86 to move up and down, thereby driving the guide mechanism 10 to move up and down, so that the guide mechanism 10 can perform gas injection on the upper and lower positions of the inner wall of the solar crucible.

[0045] like Figure 17-18As shown, the reversing mechanism 9 includes an installation cabin 91, a rotating ring 92, a reversing 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 in the installation cabin 91. The guide mechanism 10 is arranged at the rotating ring 92. The reversing motor 93 is fixedly connected to the right side of the installation cabin 91. The gear transmission pair 94 is connected between the output shaft of the reversing 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 of the installation cabin 91. The lower side of the first rotary joint 95 is connected to the guide mechanism 1 0 is fixedly connected. Two first hoses 96 are fixedly connected to the upper side of the first rotary joint 95. The first hoses 96 are both connected to the air supply mechanism 12. The rear first hose 96 is used to input heating air, and the front first hose 96 is used to input plasma gas. The first hose 96 is a high-temperature resistant pipe structure. The way in which the rotating ring 92, the reversing motor 93, the gear transmission pair 94 and the first rotary joint 95 are installed in the installation chamber 91 can reduce the impact of high temperature on the electronic components and control components therein, thereby preventing the rotating ring 92, the reversing motor 93, the gear transmission pair 94 and the first rotary joint 95 from being affected by the high-temperature working environment and causing failure.

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

[0047] Such as Figure 17-18 As shown, the guiding mechanism 10 includes an extension tube 101 and a nozzle 102. The extension tube 101 is fixedly connected to the rotating ring 92. The upper end of the extension tube 101 is fixedly connected to the first rotating joint 95. The extension tube 101 can be rotated through the first rotating joint 95. The nozzle 102 is detachably installed on the lower side of the extension tube 101. The number of nozzles 102 is not unique. The nozzles 102 have a spray angle of 30-60 degrees downward. The downward spray angle of the nozzle 102 can prevent the ejected plasma gas from being directly sprayed vertically on the inner wall of the crucible, thereby avoiding damage caused by the vertical impact of the high-temperature plasma gas on the inner wall surface of the crucible.

[0048] The heating and plasma gas source delivered from the gas supply mechanism 12 will be sprayed obliquely downward onto the surface of the inner wall of the crucible through the oblique downward structure of the nozzle 102, so that the slag on the surface of the inner wall of the crucible is blown off by the gas, while maintaining the temperature of the inner wall of the crucible to avoid rapid temperature loss due to the slag removal process. The oblique downward spraying method can guide the heating and plasma gases to flow downward along the impact direction after blowing off the slag 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] like Figure 6-Figure 8As shown, the exhaust mechanism 11 includes an exhaust pipe 111, a main pipe 112 and an exhaust end 113. The exhaust pipes 111 are respectively installed in the exhaust hole structure of the lower package frame 5. The exhaust pipe 111 is a hollow pipe structure. The exhaust pipe 111 is interconnected with the enclosed space of the enclosing frame 2. The main pipe 112 is fixedly connected between the opposite sides of the exhaust pipe 111. The main pipe 112 is in an interconnected state on the right side. The right end of the main pipe 112 is fixedly connected to the exhaust end 113, and the exhaust end 113 is connected to the external exhaust pump.

[0050] The exhaust end 113 is connected to the external exhaust pump, gas cooling machine and dust collection bag, and the external exhaust pump is turned on. The exhaust pump will extract the slag-containing gas in the enclosed space formed between the solar crucible, the contact frame 6, the surrounding frame 2 and the end cover 3 through the main pipe 112 and the exhaust pipe 111, and cool it down through the gas cooling machine. The solid slag is then collected through the dust collection bag for subsequent processing. In this way, the guide mechanism 10 can remove the slag inside the crucible while quickly sucking out the slag-containing gas, balancing the air pressure in the enclosed space formed, and avoiding the harm caused by the direct discharge of the slag-containing gas to the outside.

[0051] like Figure 6 and Figure 16 、 Figure 17 and Figure 18 As shown, the air supply mechanism 12 includes a placement sleeve 121, a corrugated hose 122, an air supply end 123 and a second hose 124. Two groups of placement sleeves 121 are fixedly connected to the right side of the surrounding frame 2. The placement sleeve 121 is a pipeline structure that is open to the left side of the surrounding space of the surrounding frame 2. The right side wall of the placement sleeve 121 is fixedly connected with a corrugated hose 122. The corrugated hose 122 is a high-temperature resistant elastic retractable structure. The right side of the placement sleeve 121 is fixedly connected with an air supply end 123. The air supply end 123 is respectively connected to the right end of the adjacent corrugated hose 122 and is interconnected. The rear air supply end 123 is connected to the external heating source, and the front air supply end 123 is connected to the external plasma gas source. The left end of the corrugated hose 122 is fixedly connected with the second hose 124, and the second hose 124 is respectively connected to the adjacent first hose 96.

[0052] The front gas supply end 123 is connected to an external plasma gas source, and the rear gas supply end 123 is connected to an external heating source. The external heating source and plasma gas source are turned on, so that a certain proportion of the heating source and the plasma gas source are input to the nozzle 102 for spraying, so that the heating gas and plasma gas impact the inner wall of the crucible to remove slag.

[0053] like Figure 2 、 Figure 4 and Figure 19As shown, it also includes an air supply mechanism 13, which includes a mounting 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 and quickly blow a large amount of warm air into the enclosed space in the enclosed frame 2, while improving the exhaust power of the exhaust mechanism 11, so that the enclosed space in the enclosed frame 2 can quickly remove the residual floating scum and prevent the scum from re-adhering to the inner wall of the crucible. The upper side of the end cover 3 is fixedly connected to the mounting pipe 131, which is a pipe structure with an open lower side. The mounting pipe 131 Electric slide rails 132 are fixedly connected to the left and right side walls of the inner wall. The electric slide rails 132 are vertical track pairs controlled by a servo system. An air supply pipe 133 is fixedly connected between the moving parts of the electric slide rails 132. The air supply pipe 133 is located on the lower side of the mounting tube 131 and is a sliding sealed connection. The air supply pipe 133 is a heat-resistant hollow pipe structure. An air supply hose 134 is fixedly connected to the upper end of the air supply pipe 133. An air supply end 135 is fixedly connected to the upper side of the mounting tube 131. The air supply end 135 is used to connect to an external heating source. The lower end of the air supply pipe 133 is fixedly connected to a diffusion component 14. The diffusion component 14 is used to output the input warm air in a high-pressure jet inside the crucible.

[0054] After the inner wall of the crucible is deslagging 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, so that the air supply pipe 133 drives the diffusion component 14 to enter the crucible. At this time, the external heating source can be started to input a large amount of heating air into the air supply pipe 133, and at the same time, the exhaust power of the exhaust mechanism 11 is increased. The large amount of heating air input from the air supply pipe 133 will be quickly ejected through the diffusion component 14, causing the diffusion component 14 to rotate in the crucible to accelerate the movement of the floating scum in the crucible, thereby increasing the speed at which the scum is extracted by the exhaust mechanism 11, so that the surrounding space in the surrounding frame 2 can quickly remove the residual floating scum, and prevent the scum from re-adhering to the inner wall of the crucible.

[0055] like Figure 19 As shown, the diffusion assembly 14 includes a second rotary joint 141, a transverse angled air duct 142 and an eccentric angled 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. The transverse angled air duct 142 is fixedly connected to the front and rear positions of the lower side of the rotating part of the second rotary joint 141. The eccentric angled air duct 143 is fixedly connected to the left and right positions of the lower side of the rotating part of the second rotary joint 141. The inclination angles of the transverse angled air duct 142 and the eccentric angled 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 transverse angled air duct 142 and the eccentric angled air duct 143 to accelerate the movement of the floating slag in the crucible. At the same time, the transverse angled air duct 142 and the eccentric angled air duct 143 are pushed by the air flow to rotate counterclockwise, so that the transverse angled air duct 142 and the eccentric angled air duct 143 can transport high-temperature gas to the inside of the crucible in all directions.

[0057] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
