AI Technical Summary
In existing flame furnace tin bath technology, it is difficult to precisely control the width of the glass molten metal during the cooling and forming process in the tin bath. When adjusting the spacing of the width adjustment plates, the height of the liquid tin surface fluctuates greatly, and the heat is not effectively recovered, resulting in large deviations in glass product specifications, unstable quality, and high energy consumption.
The system employs a synchronous adjusting slide rail and slider in conjunction with a width adjusting plate. The spacing between the width adjusting plates is precisely adjusted by working in tandem with an adjusting electric cylinder and a synchronous rack. An adaptive piston plate is set to adjust the volume of the cavity and stabilize the liquid tin surface. A heat-absorbing part is installed to recover the heat above the tin pool and convert it into electrical energy using a secondary generator. A floating roller and a thickness-controlling electric cylinder adjust the glass thickness.
This achieves high dimensional accuracy and consistent product quality in finished glass products, reduces production energy consumption, improves production efficiency and glass thickness uniformity, and reduces the difficulty and cost of subsequent processing.

[0002] Currently, most borosilicate glass production utilizes flame furnace tin bath technology, where molten glass gradually cools and solidifies on the surface of liquid tin. However, existing tin bath devices often suffer from the following shortcomings: First, during the cooling and solidification process of the molten glass in the tin bath, the width adjustment is difficult to control precisely, resulting in significant deviations in glass product specifications and failing to meet the demands of high-precision production.

Detailed Implementation
[0024] The following is in conjunction with the appendix Figures 1-8 The technical solution of the present invention will be further illustrated through specific embodiments.
[0025] This invention provides a flame furnace borosilicate glass production device, including a tin bath 101. Two parallel and symmetrically arranged width-adjusting plates 103 are slidably sealed on the inner wall of the tin bath 101. The two width-adjusting plates 103 and the inner wall of the tin bath 101 form an adjustable cavity, which communicates with an adaptation piston cavity 105 fixed to the lower surface of the tin bath 101. An adaptation piston plate 104 is slidably sealed on the inner wall of the adaptation piston cavity 105. The adaptation piston plate 104 controls the movement of the adaptation piston cavity... The displacement inside 105 keeps the volume of the cavity constant; a heat-absorbing part is provided above the tin pool 101 for energy recovery; two transmission roller supports 124 are fixedly installed on the side of the tin pool 101, and multiple transmission rollers 125 are arranged equidistantly between the two transmission roller supports 124; a heating plate 126 is fixedly installed on the top edge of the side of the tin pool 101, the upper surface of the heating plate 126 is flush with the top edge of the tin pool 101, and a floating roller 127 is provided above the heating plate 126. The floating roller 127 is rotatably mounted on two floating roller supports 121, which in turn are rotatably mounted on two transfer roller supports 124. The two floating roller supports 121 are fixedly connected by a rotating shaft. An adjusting lever 122 is fixedly mounted on one of the floating roller supports 121, and a thickness control cylinder 123 is movably mounted on one of the transfer roller supports 124. The telescopic cylinder end of the thickness control cylinder 123 is movably engaged with the transfer roller support 124, and the telescopic rod end of the thickness control cylinder 123 is movably connected to the adjusting lever 122. A motor for driving the rotation of the floating roller 127 is fixedly mounted on one of the floating roller supports 121. Multiple floating rollers 127 can be installed on the heating tray 126 to gradually pull and extrude the molten glass solution. It should be noted that the proportional lengths of the transfer roller bracket 124, heating tray 126, tin pool 101, and width adjustment plate 103 in the figure are not the actual proportional lengths. The proportional lengths of the transfer roller bracket 124, heating tray 126, tin pool 101, and width adjustment plate 103 in the figure have been shortened.
[0026] A gantry frame 116 is fixedly installed on the tin bath 101. A heat absorption section is provided directly above the tin bath 101. The heat absorption section includes a heat absorption plate 113 and a heat dissipation cavity plate 115. The heat absorption plate 113 and the heat dissipation cavity plate 115 are fixedly installed on the gantry frame 116. An array of power generation secondary plates 114 is provided between the opposite surfaces of the heat absorption plate 113 and the heat dissipation cavity plate 115 for recovering the heat energy above the tin bath 101. A heat absorption sheet 112 is fixedly fitted on the lower surface of the heat absorption plate 113. A synchronous adjustment slide rail 111 is fixedly installed in the middle of the lower surface of the heat absorption plate 113. Two symmetrically arranged synchronous adjustment sliders 110 are slidably installed on the lower surface of the synchronous adjustment slide rail 111. Each synchronous adjustment slider 110 is movably connected to two width adjustment plates 103 through two synchronous adjustment connecting rods 109 for driving the two width adjustment plates 103 to move synchronously relative to each other.
[0027] Each width adjustment plate 103 has two parallel guide rods 102 fixedly mounted on it, and all guide rods 102 are slidably engaged with the solder bath 101. A crossbeam plate 136 is fixedly mounted on the two guide rods 102 corresponding to one of the width adjustment plates 103. A gearbox mounting plate 131 is fixedly mounted on the lower surface of the solder bath 101 near the crossbeam plate 136. A synchronous rack 134 is slidably mounted on the gearbox mounting plate 131, and the top of the synchronous rack 134 is movably connected to the crossbeam plate 136 via a drive push-pull rod 135. A gearbox 130 is also fixedly mounted on the gearbox mounting plate 131, and a synchronous gear 133 that meshes with the synchronous rack 134 is rotatably mounted on the gearbox mounting plate 131. The synchronous gear 133 is connected to the input shaft of the gearbox 130 via a second chain 132. A lead screw 106 is fixedly mounted on the piston plate 104. The lead screw 106 is slidably and rotatably mounted on the nut and gearbox bracket 108. The nut and gearbox bracket 108 is fixedly mounted on the piston chamber 105. A nut and gearbox 107 is rotatably mounted on the nut and gearbox bracket 108. The nut and gearbox 107 is threaded onto the lead screw 106. The nut and gearbox 107 is connected to the output shaft of the gearbox 130 via a first chain 129.
[0028] An inclined feeding trough 128 is fixedly installed on the top edge of the solder pool 101 away from the conveyor roller bracket 124. The solder pool 101 is fixedly installed on the base 138. An adjusting electric cylinder 137 is fixedly installed on the base 138 or the gearbox mounting plate 131. The end of the telescopic rod of the adjusting electric cylinder 137 is fixedly connected to the synchronous rack 134. The interior of the heat dissipation cavity plate 115 and the floating roller 127 is hollow. One end of the floating roller 127 is connected to the water inlet of the heat dissipation cavity plate 115 through a first pipe 118. The end of the floating roller 127 connected to the first pipe 118 is also connected to a second pipe 119. The first pipe 118 and the second pipe 119 form a three-way pipe with the floating roller 127. The connection between the second pipe 119 and the first pipe 118 and the floating roller 127 adopts a rotary seal. The first pipe 118 and the second pipe 119 are respectively connected in series with a first valve 117 and a second valve 120. The heat dissipation cavity plate 115 is provided with an inlet and an outlet. The outlet of the heat dissipation cavity plate 115 and the end of the float roller 127 away from the second pipe 119 are connected to the heat exchanger through pipes and a water pump. The end of the second pipe 119 and the float roller 127 away from the first pipe 118 are connected to another heat exchanger through pipes and a water pump. Both heat exchangers are for heat dissipation, dissipating heat from the float roller 127 and the coolant inside the heat dissipation cavity plate 115.
[0029] The outlet of the melting furnace is connected to the feeding trough 128, allowing the molten glass in the melting furnace to flow onto the feeding trough 128. Before this, liquid tin (with heating equipment inside) needs to be placed inside the tin bath 101. The molten glass will flow into the surface of the liquid tin inside the tin bath 101, and the molten glass can flow evenly towards the transfer roller 125 on the surface of the liquid tin. During this process, the width of the molten glass, i.e., the width of the formed glass, is controlled by the spacing of the two width-adjusting plates 103 (the temperature of the liquid tin inside the tin bath 101 gradually decreases from the feeding trough 128 to the transfer roller 125, gradually solidifying the molten glass). The two width-adjusting plates 103... The spacing adjustment is achieved by controlling the adjusting electric cylinder 137. The extension rod of the adjusting electric cylinder 137 drives the synchronous rack 134 to slide on the gearbox mounting plate 131. The synchronous rack 134 will drive the push-pull rod 135 to pull the crossbeam plate 136 to move along the axial direction of the guide rod 102. The movement of the crossbeam plate 136 will drive the guide rod 102 to move. The guide rod 102 will drive the width adjustment plate 103 to move. The width adjustment plate 103 will drive another width adjustment plate 103 to move synchronously through the synchronous adjusting connecting rod 109 and the synchronous adjusting slider 110, thereby adjusting the spacing between the two width adjustment plates 103 (during this process, the synchronous adjusting slider 110 will slide on the synchronous adjusting slide rail 111). At the same time, the change in the distance between the two width adjustment plates 103 will cause the volume of the cavity formed by the two width adjustment plates 103 and the synchronous adjustment slider 110 to change. Therefore, in order to ensure that the liquid tin surface does not shift, it is necessary to control the up and down movement of the adaptive piston plate 104 to change the volume of the cavity. Specifically, when the synchronous rack 134 moves, it will drive the synchronous gear 133 to rotate. The synchronous gear 133 drives the input shaft of the gearbox 130 to rotate through the second chain 132. The output shaft of the gearbox 130 will drive the nut sprocket 107 to rotate through the first chain 129. The nut sprocket 107 drives the lead screw 106 to move along its own axial direction. The lead screw 106 will then drive the adaptive piston plate 104 to move synchronously.
[0030] The molten glass flowing onto the heating support plate 126 is shaped by the floating roller 127 (the heating support plate 126 has a heating unit embedded inside). At this point, the molten glass has cooled to a certain temperature (reduced fluidity). The thickness of the glass after cooling is controlled by adjusting the distance between the floating roller 127 and the heating support plate 126. Specifically, the extension rod of the thickness control cylinder 123 is controlled. The extension rod of the thickness control cylinder 123 drives the floating roller support 121 to swing on the transfer roller support 124 by adjusting the swing rod 122, thereby controlling the distance between the floating roller 127 and the heating support plate 126. The corresponding motor can control the rotation of the floating roller 127, and the floating roller 127 is used to traction the molten glass (multiple floating rollers 127 work on the same principle, equivalent to an array of structures). After shaping, the molten glass gradually cools and solidifies on the heating plate 126 (the temperature on the heating plate 126 gradually decreases along the direction of movement of the molten glass). Finally, the cooled molten glass is transferred to the next station by the transfer roller 125 (at this time, the glass still has a certain temperature, and by extending the length of the transfer roller 125, the glass is finally cooled).
[0031] As the molten glass flows over the liquid tin inside the tin pool 101, the heat it releases heats the heat absorber plate 113, creating a temperature difference between the two surfaces of the generator secondary plate 114. The generator secondary plate 114 then generates electricity, converting excess heat into electrical energy. When the first valve 117 is open (and the second pipe 119 is closed), the coolant in the cooling system for the float roller 127 and the heat dissipation chamber plate 115 first dissipates heat from the float roller 127, then flows through the first pipe 118 to the heat dissipation chamber plate 115, finally absorbing heat from the heat dissipation chamber plate 115 (increasing the temperature difference between the two surfaces of the generator secondary plate 114, thus increasing power generation; this is generally used after shutdown), and finally flows to the heat exchanger for further cooling. Alternatively, the first valve 117 can be closed and the second pipe 119 opened, allowing the coolant in the other heat exchanger to cool only the float roller 127. The float roller 127 is equipped with a temperature monitoring unit, enabling more accurate closed-loop temperature control of the float roller 127.

10. A process for producing borosilicate glass using the flame furnace borosilicate glass production equipment as described in claim 9, characterized in that, Includes the following steps: S1. The molten glass at the outlet of the furnace is introduced into the inclined feeding trough (128); the tin pool (101) is preheated and stored in liquid tin. After the molten glass flows into the tin pool (101) from the feeding trough (128), it gradually flows evenly towards the transfer roller (125) on the surface of the liquid tin. S2. During the flow of molten glass, the synchronous rack (134) is driven to move by the electric cylinder (137). The synchronous rack (134) drives the crossbeam plate (136) to move by the drive push-pull rod (135), so that the width adjustment plate (103) slides synchronously relative to the guide rod (102) to adjust the width of the molten glass in the tin pool (101). During the movement of the synchronous rack (134), the synchronous gear (133), gearbox (130) and nut toothed plate (107) are driven to move. The lead screw (106) drives the displacement of the adaptive piston plate (104) to adjust the volume of the adaptive piston chamber (105) and maintain the stability of the liquid tin surface position in the tin pool (101). S3. After the molten glass flows to the heating support plate (126) area at the edge of the tin pool (101), it is shaped and pulled by the floating roller (127); the thickness control electric cylinder (123) drives the adjusting swing rod (122) to rotate, and the floating roller support (121) swings on the transfer roller support (124) to adjust the distance between the floating roller (127) and the heating support plate (126) and control the thickness of the molten glass. S4. The molten glass, after being shaped by the floating roller (127), gradually flows on the heating tray (126) and gradually cools down and solidifies. The heating tray (126) is equipped with a partitioned heating unit, which gradually reduces the temperature along the direction of the molten glass movement to achieve initial solidification of the glass. Then, the initially cooled glass plate is smoothly transported to the next station by the transfer roller (125) for further cooling and stable forming. S5. The residual heat released during the flow and forming of the molten glass on the liquid tin in the tin pool (101) is captured by the heat absorption plate (112) below the heat absorption plate (113) and heats the secondary power generation plate (114). The energy is recovered by utilizing the temperature difference generated by the secondary power generation plate (114).
