Description

Technical Field

[0001] The utility model relates to the technical field of glass furnaces, and particularly relates to a variable-diameter flow hole for a photovoltaic glass furnace. Background Art

[0002] In recent years, with the booming development of the photovoltaic new energy industry, the demand for photovoltaic glass has been increasing day by day. The production of glass is inseparable from furnaces. A reasonable furnace structure and melting method can ensure the yield of glass products and make glass enterprises more competitive in the market.

[0003] Publication No. (CN105417932B) discloses a flow hole brick for a glass substrate furnace, including a brick body. A flow hole penetrating through its thickness is formed on the brick body. A protection tube for preventing the brick body from being eroded is installed in the flow hole. The tube wall of the protection tube fits the hole wall of the flow hole. Among them, the inner end of the protection tube is formed into a horn structure with a large opening facing inward;

[0004] In the process of glass production, the first step is the melting of glass batch. The melting temperature can often reach about 1500 °C. Only refractory bricks can be used to build the melting pool to complete the melting of glass batch. Due to the constraints of the physical and chemical properties of refractory bricks themselves, as shown in the above technology, the flow hole is opened in the brick body, making the structure of the glass furnace built with refractory bricks relatively fixed. After production starts, the relevant structures affecting the quality of glass liquid cannot be changed in the hot state. If the furnace structure design is incorrect, only the furnace structure can be changed after cooling. The time cycle is long, and a single heating and cooling operation can take several months. At the same time, the strength of the refractory bricks used for furnace lining will change after secondary heating, and even crack or be damaged directly, resulting in huge losses. For this reason, we propose a variable-diameter flow hole for a photovoltaic glass furnace. Content of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the utility model provides a variable-diameter flow hole for a photovoltaic glass furnace. By arranging symmetrically distributed baffle plates on the outer side of the flow hole body, the size of the flow hole body is reduced by the mutual approach of the two baffle plates, the flow rate of glass liquid is reduced, the furnace state is stabilized, and the product yield is improved. After the overall state of the furnace is stable, the size of the flow hole can be enlarged to increase the output.

[0006] In order to solve the above technical problems, the utility model solves the phenomenon that the size of the flow hole is fixed and difficult to adjust through the following technical solutions.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A variable-diameter flow-through hole for a photovoltaic glass furnace, comprising the bottom of the glass furnace pool. The top of the bottom of the glass furnace pool is provided with the pool wall of the glass furnace. The middle bottom of the pool wall of the glass furnace is provided with the main body of the flow-through hole. The inner part of the pool wall of the glass furnace is provided with an installation groove. Baffle plates are symmetrically arranged in the installation groove, and a pull plate is fixedly arranged at the top of the baffle plates.

[0009] In some embodiments, the two baffle plates are symmetrically arranged outside the main body of the flow-through hole. A convex plug is fixedly arranged on the outside of one baffle plate, and a concave plug is fixedly arranged on the outside of the other baffle plate. The central groove of the convex plug cooperates with the concave plug. Through the cooperation of the convex plug and the concave plug, the size of the main body of the flow-through hole can be adjusted.

[0010] In some embodiments, the convex plug is arranged at the main body of the flow-through hole, and the height of the convex plug is equal to the diameter of the main body of the flow-through hole, so as to prevent the glass liquid from entering between the two baffle plates.

[0011] In some embodiments, the width of the convex plug is greater than the diameter of the main body of the flow-through hole. When the main body of the flow-through hole is completely exposed, the convex plug and the concave plug form a square space to wrap the main body of the flow-through hole, so as to prevent the glass liquid from flowing into between the two baffle plates.

[0012] In some embodiments, a pointer is fixedly arranged at the bottom of the pull plate, and a scale line is arranged outside the pool wall of the glass furnace. The pointer is arranged outside the scale line, so that the distance between the two baffle plates can be accurately adjusted, and further the size of the main body of the flow-through hole can be adjusted.

[0013] In some embodiments, the baffle plates are made of high-zirconium materials to improve the service life of the baffle plates.

[0014] In some embodiments, the two baffle plates are integrally formed with the convex plug and the concave plug respectively to improve the strength of the connection between the baffle plates and the convex plug and the concave plug.

[0015] In some embodiments, there are two groups of scale lines, which are symmetrically arranged on both sides outside the main body of the flow-through hole. Each baffle plate is adjusted by a group of scale lines to ensure that the space formed by the convex plug and the concave plug is concentric with the center of the main body of the flow-through hole.

[0016] In some embodiments, auxiliary lines are arranged outside the pointer, and the position of the baffle plate is determined by the coincidence of the auxiliary lines and the scale lines to improve the adjustment accuracy.

[0017] In some embodiments, the outer sides of the convex plug and the concave plug are both slidably fitted with the inner part of the installation groove to improve the sealing performance between the outer sides of the convex plug and the concave plug and the inner part of the installation groove and prevent the glass liquid from flowing into the installation groove.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The utility model reduces the size of the liquid flow hole body by symmetrically arranging baffle plates on the outer side of the liquid flow hole body, reduces the flow rate of the molten glass, stabilizes the state of the kiln, improves the product yield, and can expand the size of the liquid flow hole after the overall state of the kiln is stable, thereby increasing the output;

[0020] The liquid flow hole body is shielded through the cooperation of the convex insertion block and the concave insertion block, and the size of the liquid flow hole body is adjusted, so that it can be avoided that the molten glass enters the installation groove of the glass kiln pool wall when flowing through the liquid flow hole body, which is convenient for subsequent cleaning of the interior of the device;

[0021] The movement of the baffle plate is controlled by a pointer and a scale line, and the size of the space formed by the combination of the convex insertion block and the concave insertion block can be accurately adjusted, and then the size of the liquid flow hole body can be accurately adjusted.

[0034] Embodiment:

[0035] Please refer to Figures 1-6 , a variable-diameter flow hole of a photovoltaic glass kiln, including the bottom 1 of the glass kiln, a glass kiln wall 2 is provided on the top of the bottom 1 of the glass kiln, a flow hole body 3 is provided at the middle bottom of the glass kiln wall 2, an installation groove 4 is provided inside the glass kiln wall 2, baffle plates 5 are symmetrically provided in the installation groove 4, and a pull plate 6 is fixedly provided on the top of the baffle plate 5.

[0036] In the embodiment of the present application, two baffle plates 5 are symmetrically arranged outside the flow hole body 3. A convex plug 7 is fixedly provided on the outside of one of the baffle plates 5, and a concave plug 8 is fixedly provided on the outside of the other baffle plate 5. The convex plug 7 is matched with the central groove of the concave plug 8. Through the cooperation of the convex plug 7 and the concave plug 8, the size of the flow hole body 3 can be adjusted.

[0037] In the embodiment of the present application, a pointer 9 is fixedly provided at the bottom of the pull plate 6, a scale line 10 is provided outside the glass kiln wall 2, and the pointer 9 is arranged outside the scale line 10, so as to accurately adjust the distance between the two baffle plates 5, and further adjust the size of the flow hole body 3.

[0038] During the implementation process, the bottom of the glass furnace 1 is at the bottommost layer, bearing the high-temperature glass liquid. The glass furnace sidewall 2 is placed on top of the bottom of the glass furnace 1 to form the glass liquid melting pool of the glass furnace. During glass production, the high-temperature glass liquid flows into the platinum channel through the liquid flow hole body 3 to complete the homogenization work. Two baffle plates 5 made of high zirconium material are placed in the installation groove 4 and have two degrees of freedom in the left and right directions. The glass furnace sidewall 2 is composed of two high zirconium sidewall bricks, and the installation groove 4 left in the middle is the masonry space for installing the baffle plate 5. When the flow rate of the glass liquid in the furnace is too fast, resulting in an increase in glass product defects, the baffle plate 5 is pushed towards the liquid flow hole body 3. The size of the liquid flow hole body 3 is reduced through the cooperation of the concave insert block 8 and the convex insert block 7, the flow rate of the glass liquid is reduced, the furnace state is stabilized, and the product yield is improved. After the overall state of the furnace is stable, the size of the liquid flow hole body 3 can be enlarged to increase the output.

[0039] The pull plate 6 is used to drive the baffle plate 5 to slide in the installation groove 4. The position of the baffle plate 5 is determined by the coincidence of the auxiliary line 11 on the pointer 9 and the scale line 10 on the outside of the glass furnace sidewall 2, and then the size of the space formed by the convex insert block 7 and the concave insert block 8 is accurately adjusted, thereby accurately adjusting the size of the liquid flow hole body 3. Since the convex insert block 7 is provided at the liquid flow hole body 3, the height of the convex insert block 7 is equal to the diameter of the liquid flow hole body 3, and the width of the convex insert block 7 is greater than the diameter of the liquid flow hole body 3. At the same time, both the outer sides of the convex insert block 7 and the concave insert block 8 are slidably fitted with the inside of the installation groove 4, which can ensure that the combination of the convex insert block 7 and the concave insert block 8 can block the outside of the liquid flow hole body 3, preventing the glass liquid from entering the installation groove 4 when flowing through the liquid flow hole body 3 and increasing the subsequent cleaning difficulty.

[0040] The two baffle plates 5 are integrally formed with the convex insert block 7 and the concave insert block 8 respectively, improving the strength of the connection between the baffle plate 5 and the convex insert block 7 and the concave insert block 8.

[0041] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the principle, any deformation or modification of the embodiments of the present invention is possible.
