Description

Technical Field

[0001] The present invention relates to the field of glass manufacturing, and particularly to a device and a manufacturing method for manufacturing radiation-proof and radiation-resistant glass. Background Art

[0002] In recent years, there are basically two methods for manufacturing radiation-proof and radiation-resistant glass. One is that platinum material tubes drip materials into brick troughs, and the materials are spread out in a high-temperature environment and formed into sheet materials through a calender. During this forming process, due to reasons such as temperature difference, the sheet materials produced often have serious stripes, the product qualification rate is low, and the formed sheet materials can be wide but not thick, with a thickness not exceeding 30 mm and a width of at most about 1300 mm. The other is that platinum material tubes drip materials onto a cast iron template for forming, and after dripping, they are spread out. Due to reasons such as temperature difference, stripes are formed, and the width that can be spread out is limited. For this method, the formed sheet materials can be thick but not wide, with a thickness that can reach about 150 mm, but the width can only be about 800 mm. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a device and a manufacturing method for manufacturing radiation-proof and radiation-resistant glass, so that the adjustment ranges of the width and thickness of the glass during production are both wide, and the product qualification rate is improved.

[0026] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] As Figures 1-5 shown, this embodiment provides a device 100 for manufacturing radiation-proof and radiation-resistant glass, including a heating and heat preservation mechanism, a glass liquid conveying mechanism 5, a template 7, and an annealing furnace.

[0030] To further improve the heat preservation effect, the heating and heat preservation mechanism further includes a heat preservation layer 4, and the heat preservation layer 4 is arranged outside the heat preservation bricks 2 located on the outside.

[0031] In this specific embodiment, the heating component 3 is a silicon carbide rod, which can be electrically heated to reach above the melting point of the glass raw material to make the glass liquid flow and form. The temperature of the glass liquid can be adjusted by controlling the heating temperature of the heating component.

[0032] Specifically, the heat preservation bricks 2 are high-aluminum bricks or mullite bricks, and the high-aluminum bricks or mullite bricks have heat preservation and high-temperature resistance properties. The high-aluminum bricks in this embodiment are alumina bricks.

[0037] Specifically, the V-shaped shell 53 includes two inverted trapezoidal plates and two inclined plates. The left sides of the two inverted trapezoidal plates are connected by one inclined plate, and the right sides of the two inverted trapezoidal plates are connected by the other inclined plate. In this embodiment, the rear plate 55 is flush with the inverted trapezoidal plate at the rear side of the V-shaped shell 53.

[0038] The glass liquid delivery mechanism 5 in this embodiment is made of platinum. Specifically, the liquid delivery pipe, the V-shaped shell 53, and the rectangular shell are all made of platinum plates, and the thickness of the platinum plates is 0.45 mm to 0.8 mm.

The thickness of the manufactured glass 11 is less than the height of the rear plate 55, and the height of the rear plate 55 can be set according to the required thickness of the glass 11.

[0040] This embodiment further includes a cooling mechanism for cooling the template 7.

[0041] This embodiment further includes a second bracket 6. The template 7 includes a base plate and two baffles. The base plate is arranged on the second bracket 6, and the two baffles are respectively arranged on the left and right sides of the upper part of the base plate. The base plate is flush with and in contact with the bottom plate 54. The distance between the two baffles is the same as the width of the inner cavity of the rectangular housing, and the opening at one end of the template 7 close to the rectangular housing corresponds to the opening position at the front end of the rectangular housing.

[0042] Specifically, the cooling mechanism includes a cooling pipe arranged in the base plate. Cooling water is passed through the cooling pipe to cool the glass liquid on the template 7, thereby improving the forming speed.

[0043] Specifically, the annealing furnace includes a steel member 8, a conveying mechanism, and a furnace chamber 9. The furnace chamber 9 is arranged above the steel member 8, and the conveying mechanism is arranged on the steel member 8 and is used to convey the formed glass 11 into the furnace chamber 9.

[0044] This embodiment also provides a manufacturing method based on the radiation-proof and radiation-resistant glass manufacturing device 100, including the following steps: The glass liquid enters the V-shaped housing 53 through the liquid supply pipe at the bottom, floats to the opening at the upper end of the V-shaped housing 53, and enters the rectangular housing through the strip-shaped opening. The heating and heat preservation mechanism provides heat energy to keep the temperature at about 1200 °C, so that the glass liquid remains in a liquid state; the glass liquid enters the template 7 and cools and forms to obtain the glass 11, and the glass 11 is annealed in the annealing furnace after being drawn. Specifically, the glass 11 is drawn and enters above the transmission mechanism, and is conveyed into the furnace chamber 9 by the conveying mechanism.

[0045] Specifically, the glass raw materials supplied to the melting furnace are heated to obtain molten glass liquid, and then the molten glass liquid flows into the liquid supply pipe through processes such as clarification and stirring, and the flow rate of the glass liquid can be adjusted according to actual needs.

[0046] In this embodiment, by adopting the V-shaped housing 53, the width of the glass liquid gradually increases during the upward floating process. When the glass liquid floats to the opening at the upper end of the V-shaped housing 53, the width of the glass liquid reaches the target width. Then, it enters the template 7 through the rectangular housing and is cooled and formed into the glass 11. The width of the opening at the upper end of the V-shaped housing 53 and the width of the inner cavity of the rectangular housing can be set according to the required width of the glass 11. By adjusting the flow rate and temperature of the glass liquid, the thickness of the glass 11 can be controlled, so that the adjustment ranges of the width and thickness of the glass 11 in production are both wide, greatly increasing the types of specifications that can be produced. Specifically, the width of the glass 11 that can be produced is 400 mm to 1600 mm, and the thickness is 8 mm to 160 mm. At the same time, the traditional method of forming by dropping materials from a material pipe is changed, avoiding the problem of stripes that are easily caused due to temperature differences and other reasons after dropping and then spreading out, and improving the product qualification rate.

The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
