Description

Technical Field

[0001] This utility model relates to the field of glass kiln technology, and in particular to a novel exhaust brick for the feed channel of a glass kiln. Background Technology

[0002] In the production and processing of glass bottles, the glass furnace is a crucial piece of equipment, and the exhaust system of the feeding channel directly affects the stable operation and production efficiency of the furnace. Currently, in the field of exhaust technology for glass furnace feeding channels, the most widely used method is still the traditional chimney exhaust structure. However, this traditional chimney structure has revealed many insurmountable technical defects in practical use.

[0003] Specifically, glass furnaces generate large amounts of flue gas during high-temperature operation. This flue gas is not only high in temperature but also complex in composition, inevitably containing sulfides released from high-temperature glass and impurities such as dust. As the high-temperature flue gas is discharged upwards through the chimney, its temperature gradually decreases with increasing height and the influence of the ambient temperature. Sulfides have a significant characteristic: they are usually gaseous at high temperatures and can mix uniformly with other substances. However, as the temperature decreases, their solubility or saturation changes significantly. When the temperature drops to a certain level, sulfides precipitate from the flue gas and condense on the inner wall of the chimney, especially on the chimney cover. Because the sulfide condensate has a certain degree of adhesion, it gradually accumulates on the surface of the cover, requiring regular manual cleaning and maintenance.

[0004] However, manual cleaning carries significant operational risks and potential pollution hazards. Firstly, during cleaning, condensate can easily fall from inside the chimney. If it falls into the furnace exhaust duct below, it will inevitably enter the molten glass inside the furnace, causing serious secondary pollution and directly affecting the quality of the finished glass bottles. Secondly, as condensate accumulates, even without manual cleaning, a certain level of accumulated condensate may fall due to gravity or other factors, again posing a risk of contaminating the molten glass.

[0005] Furthermore, traditional chimney exhaust structures generally lack an effective automatic adjustment mechanism for exhaust volume. This means that the exhaust system often operates in a fixed mode, unable to flexibly adjust the exhaust port size according to real-time changes in the flue gas pressure inside the kiln. When the flue gas pressure in the kiln is low, excessive exhaust is prone to occur, leading to a significant loss of heat inside the kiln. This not only increases energy consumption but also reduces the overall energy utilization efficiency, contradicting the current advocacy of energy conservation, emission reduction, and green production. Existing technologies urgently need improvement to address these issues. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a new type of exhaust brick for the feed channel of a glass kiln.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a novel exhaust brick for a glass kiln feed channel, comprising a glass kiln, wherein an exhaust channel is provided inside the glass kiln, an exhaust brick body is fixed to the top of the glass kiln, a downward inclined channel is provided inside the exhaust brick body to connect with the exhaust channel, an upward inclined channel is provided at the outlet of the downward inclined channel, a cover plate is provided at the outlet of the upward inclined channel, side baffles are symmetrically fixedly connected to the top of the exhaust brick body, the cover plate is rotatably connected to the two side baffles via a rotating shaft, an exhaust port is provided on the cover plate, the exhaust port is connected to the outlet of the upward inclined channel, and a receiving groove is provided on the exhaust brick body for accommodating the cover plate;

[0008] A spring sheet is fixedly connected to the side of the cover plate away from the exhaust port by a mounting rod, and one end of the spring sheet is fixed to the exhaust brick body;

[0009] The main body of the exhaust brick is also provided with a placement chamber, which is located below the upper inclined channel, and an impurity collection mechanism is provided inside the placement chamber.

[0010] Preferably, the cover plate has an arc-shaped structure, and the exhaust port is located in the middle of the arc-shaped surface of the cover plate.

[0011] Preferably, both side baffles have arc-shaped elongated slots on their side walls, and a crossbar is provided inside both arc-shaped elongated slots. The crossbar is fixedly connected to the mounting rod on the cover plate.

[0012] Preferably, the impurity collection mechanism includes a detachable collection box disposed in the placement chamber, a card seat disposed on the outside of the collection box, and a pull block for pulling the collection box, and a lever rotatably connected to the exhaust brick body and engaging with the card seat.

[0013] Preferably, the card holder has a C-shaped slot structure, and the card rod engages in the C-shaped slot of the card holder.

[0014] Preferably, the pull block is fixed to the outer wall of the collection box, and the pull block is provided with anti-slip texture.

[0015] Preferably, the rotating shaft is a pin structure, and both the cover plate and the side baffle are provided with shaft holes adapted to the rotating shaft. The rotating shaft passes through the shaft holes to realize the rotational connection between the cover plate and the side baffle on the top of the exhaust brick body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The exhaust brick body of the glass kiln feed channel provided by this utility model has significant beneficial effects. First, by innovatively designing downward and upward inclined channels inside the exhaust brick body, the exhaust path of the flue gas is cleverly extended, allowing the high-temperature flue gas to gradually cool down during the exhaust process. This structural design makes it easier for impurities such as sulfides and dust contained in the high-temperature flue gas to condense at the upward inclined channel and cover plate. The condensate produced can naturally fall down the bottom of the upward inclined channel into the collection box located in the placement chamber below, thus effectively avoiding the risk of condensate falling directly into the kiln exhaust channel and contaminating the molten glass, significantly improving the purity of the molten glass and the quality of the glass products.

[0018] Secondly, this invention cleverly utilizes the cooperation between a spring plate and a cover plate to construct an automatic adjustment mechanism for the size of the exhaust port. When the flue gas pressure inside the kiln changes, the spring plate can sensitively detect this and drive the cover plate to rotate accordingly, automatically adjusting the size of the exhaust port and achieving intelligent control of the exhaust volume. This automatic adjustment function can effectively avoid heat loss in the kiln caused by excessive exhaust, significantly improve energy utilization efficiency, reduce energy consumption, and conform to the concept of green production.

[0019] In addition, to facilitate the cleaning of the collected condensate, this utility model also features a detachable collection box structure, along with components such as levers, seats, and pull blocks, making the disassembly and installation of the collection box very simple and quick, greatly reducing the workload of manual maintenance and improving maintenance efficiency.

[0027] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0028] like Figures 1 to 6 The present invention relates to a novel exhaust brick for a glass kiln feed channel, comprising a glass kiln 1, an exhaust channel 101 inside the glass kiln 1, an exhaust brick body 2 fixed on the top of the glass kiln 1, a downward inclined channel 13 connected to the exhaust channel 101 inside the exhaust brick body 2, an upward inclined channel 14 connected to the outlet of the downward inclined channel 13, a cover plate 6 at the outlet of the upward inclined channel 14, side baffles 5 symmetrically fixedly connected to the top of the exhaust brick body 2, and the cover plate 6 rotatably connected to the two side baffles 5 via a rotating shaft 18, an exhaust port 10 opened on the cover plate 6, the exhaust port 10 connected to the outlet of the upward inclined channel 14, and a receiving slot 16 for accommodating the cover plate 6 on the exhaust brick body 2.

[0029] A spring plate 12 is fixedly connected to the side of the cover plate 6 away from the exhaust port 10 by a mounting rod 11, and one end of the spring plate 12 is fixed to the exhaust brick body 2;

[0030] The main body 2 of the exhaust brick is also provided with a placement chamber 15, which is located below the upper inclined channel 14. The placement chamber 15 is provided with an impurity collection mechanism.

[0031] During operation, when molten glass is conveyed through the feeding channel of glass furnace 1, the flue gas inside glass furnace 1 enters the lower inclined channel 13 through the furnace exhaust channel 101, then continues upward into the upper inclined channel 14, and then enters the cover plate 6 through the upper inclined channel 14, finally exiting through the exhaust port 10. From inside glass furnace 1, through the furnace exhaust channel 101, lower inclined channel 13, and upper inclined channel 14, and finally exiting through the exhaust port 10, the flue gas temperature gradually decreases. Sulfides typically exhibit the characteristic of being gaseous at high temperatures or uniformly mixed with other substances, and their solubility or saturation changes as the temperature decreases, leading to precipitation. When the flue gas rises to the cover plate 6, the temperature drops to a certain level, and the sulfides reach a supersaturated state, precipitating from the flue gas and condensing on the surface of the cover plate 6. When the pressure of the flue gas discharged from the upper inclined channel 14 exceeds the elastic force of the spring plate 12, the spring plate 12 undergoes elastic deformation. The flue gas pressure squeezes the cover plate 6, causing it to rotate counterclockwise along the rotating shaft 18, thereby enlarging the exhaust port 10. When the flue gas pressure decreases, the spring plate 12 squeezes the cover plate 6 again, causing it to rotate clockwise. The two sides of the cover plate 6 remain within their corresponding receiving slots 16. By making the exhaust port 10 smaller, the size of the exhaust port 10 can be adjusted to a suitable size according to the change in flue gas pressure. This allows for automatic adjustment of the exhaust volume based on the internal pressure, ensuring exhaust efficiency while avoiding heat loss due to excessive exhaust. The flue gas in the glass furnace 1 is discharged sequentially through the lower inclined channel 13, the upper inclined channel 14, and the exhaust port 10. During this process, the temperature of the discharged flue gas gradually decreases. Sulfides and dust in the high-temperature glass condense on the cover plate 6 as the flue gas rises. When the condensate falls, it falls into the impurity collection mechanism located in the placement chamber 15, facilitating the cleaning of the collected condensate.

[0032] In one embodiment of this utility model, the cover plate 6 has an arc-shaped structure, and the exhaust port 10 is located in the middle of the arc-shaped surface of the cover plate 6. More specifically, during operation, the curvature of the arc-shaped cover plate 6 can be adjusted according to the actual application scenario and exhaust requirements. For example, the arc-shaped cover plate 6 can be semi-circular, elliptical, or other shapes. The material of the arc-shaped cover plate 6 can be selected as high-temperature resistant and corrosion-resistant metal or ceramic materials to ensure its long-term stable operation under harsh conditions. The exhaust port 10 is located at the center of the arc-shaped surface of the cover plate 6. This central setting allows the exhaust port 10 to be located at the highest point of the cover plate 6, which is conducive to the concentrated discharge of flue gas and improves exhaust efficiency. At the same time, placing the exhaust port 10 in the middle of the arc-shaped surface also makes the cover plate 6 more evenly stressed when subjected to flue gas pressure, reducing the risk of excessive local stress on the cover plate 6 and improving the structural strength and service life of the cover plate 6.

[0033] As one embodiment of this utility model, arc-shaped long slots 3 are provided on the side walls of both side baffles 5. A crossbar 4 is provided inside the two arc-shaped long slots 3. The crossbar 4 is fixedly connected to the mounting rod 11 on the cover plate 6. During operation, the crossbar 4 is equivalent to adding a structural reinforcing beam above the arc-shaped long slots 3, which can effectively disperse and bear the external pressure acting on the cover plate 6. In particular, it can effectively resist the deformation of the cover plate 6 that may be caused by high-temperature flue gas, and significantly improve the overall structural strength and stability of the exhaust brick body 2.

[0034] As one embodiment of this utility model, the impurity collection mechanism includes a detachable collection box 9 disposed in the placement chamber 15, a retaining seat 8 disposed on the outside of the collection box 9, and a pull block 17 for pulling the collection box 9. A retaining rod 7 is rotatably connected to the exhaust brick body 2 and engaged with the retaining seat 8. During operation, when condensate falls, it will fall into the collection box 9 located in the placement chamber 15 for collection. Because the downward inclined channel 13 offsets the upward inclined channel 14 from the furnace exhaust channel 101, and the bottom end of the upward inclined channel 14 faces the collection box 9, the condensate can fall into the collection box 9 more easily, thereby greatly reducing the pollution of the glass melt caused by the condensate falling into the furnace exhaust channel 101 and then entering the glass furnace 1. When it is necessary to clean the collected material in the collection box 9, the retaining rod 7 is rotated to offset it from the retaining seat 8, and the collection box 9 is pulled out from the placement chamber 15 by pulling the pull block 17.

[0035] In one embodiment of this utility model, the card holder 8 has a C-shaped slot structure, and the card rod 7 engages within the C-shaped slot of the card holder 8. During operation, the card holder 8 is not a completely closed annular structure, but rather has an opening on its side, forming a C-shaped slot. The card rod 7 can then easily engage or disengage from the slot of the card holder 8 through this opening. More specifically, the width of the C-shaped opening of the card holder 8 with the C-shaped slot structure can be rationally designed according to the diameter of the card rod 7 and the assembly clearance, ensuring that the card rod 7 can not only smoothly engage within the slot but also maintain a stable connection after engagement, preventing accidental detachment. Therefore, by designing the card holder 8 as a C-shaped slot structure and engaging the card rod 7 with the C-shaped slot, rapid connection and separation between the collection box 9 and the placement chamber 15 are achieved. When users need to clean the collected items in the collection box 9, they only need to gently move the lever 7 to disengage it from the opening of the C-shaped slot, and the collection box 9 can be easily removed from the placement chamber 15. When installing the collection box 9, simply align the lever 7 with the opening of the C-shaped slot and push the collection box 9 inward so that the lever 7 is engaged in the slot to complete the installation. The operation is very simple and quick, which greatly improves maintenance efficiency and reduces the difficulty of operation.

[0036] In one embodiment of this utility model, the pull block 17 is fixed to the outer wall of the collection box 9, and the pull block 17 is provided with anti-slip texture. During operation, the pull block 17, as an independent component, is firmly fixed to the outer wall of the collection box 9 by means such as screws, rivets, or adhesives, so that the user can directly grip and apply force. The surface of the pull block 17 is provided with anti-slip texture, such as raised stripes, grid patterns, or dotted patterns processed on the surface of the pull block 17. These anti-slip textures can significantly increase the friction coefficient of the surface of the pull block 17, making it less likely for the user to slip when gripping the pull block 17. Even when wearing gloves or with wet hands, a reliable grip can be guaranteed, thereby pulling the collection box 9 more stably and reliably.

[0037] As one embodiment of this utility model, the rotating shaft 18 is a pin structure. Both the cover plate 6 and the side baffle 5 are provided with shaft holes adapted to the rotating shaft 18. The rotating shaft 18 passes through the shaft hole to realize the rotational connection between the cover plate 6 and the side baffle 5 on the top of the exhaust brick body 2.

[0038] Working principle of this utility model:

[0039] When molten glass is conveyed through the feeding channel of glass furnace 1, the flue gas inside glass furnace 1 enters the lower inclined channel 13 through the furnace exhaust channel 101, then continues upward into the upper inclined channel 14, and after passing through the upper inclined channel 14, enters the cover plate 6, and finally exits through the exhaust port 10. From inside glass furnace 1, through the furnace exhaust channel 101, lower inclined channel 13, and upper inclined channel 14, and finally exiting through the exhaust port 10, the flue gas temperature gradually decreases during this process. Sulfides, which are typically gaseous at high temperatures or uniformly mixed with other substances, decrease in solubility as the temperature decreases. Due to the characteristic of precipitation caused by changes in saturation, when the flue gas rises to the position of the cover plate 6, the temperature drops to a certain level, and the sulfides reach a supersaturated state, precipitating from the flue gas and condensing on the surface of the cover plate 6. When the pressure of the flue gas discharged from the upward inclined channel 14 is greater than the elastic force of the spring plate 12, the spring plate 12 undergoes elastic deformation. The flue gas pressure squeezes the cover plate 6, causing it to rotate counterclockwise along the rotating shaft 18, thereby enlarging the exhaust port 10. When the flue gas pressure decreases, the spring plate 12 squeezes the cover plate 6 again, causing it to rotate clockwise, with both sides of the cover plate 6 maintaining their corresponding positions. Within the receiving slot 16, by reducing the size of the exhaust port 10, the size of the exhaust port 10 can be adjusted to a suitable size according to changes in flue gas pressure. This allows for automatic adjustment of the exhaust volume based on internal pressure, ensuring exhaust efficiency while avoiding heat loss due to excessive exhaust. The flue gas inside the glass furnace 1 is discharged sequentially through the lower inclined channel 13, the upper inclined channel 14, and the exhaust port 10. During this process, the temperature of the discharged flue gas gradually decreases. Sulfides and dust in the high-temperature glass condense on the cover plate 6 as the flue gas rises. When the condensate falls, it lands on the cover plate 6. The condensate is collected in the collection box 9 located in the placement chamber 15. Because the downward inclined channel 13 offsets the upward inclined channel 14 from the furnace exhaust channel 101, and the bottom end of the upward inclined channel 14 faces the collection box 9, the condensate can fall into the collection box 9 more easily, which greatly reduces the risk of the condensate falling into the furnace exhaust channel 101 and then entering the glass furnace 1 to contaminate the glass melt. When it is necessary to clean the collected material in the collection box 9, the clamp 7 is rotated to offset it from the clamp 8, and then the collection box 9 is pulled out from the placement chamber 15 by pulling the pull block 17.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
