Description

Technical Field

[0001] This invention belongs to the technical field of glass production equipment, specifically relating to a temporary water bag device for the feeding port of a glass melting furnace. Background Technology

[0002] Before glass melting furnaces are put into formal production, they usually need to be preheated to allow the furnace to gradually heat up according to a predetermined heating curve. During the preheating process, the feeding port is close to the high-temperature area inside the furnace, which can easily lead to local overheating. Therefore, it is usually necessary to set up a temporary water tank at the feeding port to remove heat through circulating cooling water in order to protect the steel structure and related equipment near the feeding port.

[0003] Existing temporary water tanks are mostly arranged horizontally along the feeding port and suspended and fixed by components such as chains and hooks. For glass melting furnaces with a wide feeding port, the length and weight of the water tank increase accordingly. Under high temperature and continuous load, problems such as water tank deformation, uneven stress, loosening or breakage of suspension components are prone to occur, resulting in insufficient support stability and safety risks. At the same time, the cooling coverage of water tanks arranged in a single direction is limited, and some areas near the feeding area or the front end of the feeding port may still have insufficient cooling.

[0004] Therefore, it is necessary to provide a temporary water tank device that can improve the cooling capacity of the feed inlet and enhance the stability of the water tank support. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a temporary water jacket device for the feeding port of a glass melting furnace, which solves the problems of limited cooling coverage, insufficient suspension stability, and inconvenience in installation, disassembly, and water flow adjustment of existing temporary water jackets. It overcomes the insufficient cooling capacity of temporary water jackets during furnace baking, thereby further reducing the temperature at the feeding port and ensuring stable operation of the furnace baking process.

[0006] The present invention aims to solve one of the problems in the background art. The technical solution adopted by the present invention is as follows: To achieve the above-mentioned objective and other related objectives, the present invention provides the following technical solution:

[0007] A temporary water jacket device for the feeding port of a glass melting furnace is installed at the feeding port of the glass melting furnace to reduce the temperature at the feeding port during furnace firing. The device includes a first-direction water jacket, a second-direction water jacket, an inlet pipe, an outlet pipe, and a suspension assembly.

[0008] A first circulating water channel is formed inside the first directional water tank. The first directional water tank extends along the width direction of the feeding port and is suspended at the feeding port by at least two suspension components spaced apart along its length direction.

[0009] The second direction water tank forms a second circulating water channel inside. The second direction water tank extends along the depth direction of the feeding port and is fixed to the bearing structure of the feeding port.

[0010] The inlet pipe is connected to the first circulating water channel, the second circulating water channel and the main water supply pipe respectively, and the outlet pipe is connected to the first circulating water channel, the second circulating water channel and the return water main pipe respectively.

[0011] The second directional water tank is located below the first directional water tank. One end of the second directional water tank extends to the front end area of ​​the feed port away from the inside of the kiln, and the other end extends into the vertical projection area of ​​the first directional water tank, so that the second directional water tank passes through the feed area and below the first directional water tank at the same time.

[0012] When the suspension assembly is under normal load and the first directional water bag is in the working position, there is a preset gap between the upper part of the second directional water bag and the lower part of the first directional water bag; when the first directional water bag moves downward relative to the working position until the preset gap disappears, the lower part of the first directional water bag contacts the upper part of the second directional water bag and forms a supporting fit, so that at least part of the load of the first directional water bag is transferred to the load-bearing structure through the second directional water bag, and the first directional water bag is restricted from continuing to move downward.

[0013] In the first direction of the water bag, the supporting and cooperating position is located between two adjacent suspension components along the length of the water bag.

[0014] The technical solution provided in this application also has the following technical features:

[0015] Preferably, in one embodiment of this application, there are multiple first-direction water bags and multiple second-direction water bags;

[0016] Multiple first-direction water bags are arranged sequentially along the first direction, and multiple second-direction water bags are arranged at intervals along the first direction. Each second-direction water bag extends along the second direction and corresponds to at least one first-direction water bag, so that when the corresponding first-direction water bag moves downward to the point where the preset gap disappears, it forms a supporting cooperation with the first-direction water bag.

[0017] The first direction is the width direction of the feeding port, and the second direction is the depth direction of the feeding port. The first direction is perpendicular to the second direction.

[0018] Under normal suspension conditions, the two types of water bags maintain a preset gap, and the second-direction water bag does not bear the normal load of the first-direction water bag; only after the first-direction water bag abnormally moves down until the gap disappears, does the second-direction water bag trigger support, and establishes a secondary load transfer path through the support position between adjacent suspension components.

[0019] This invention utilizes the existing winch and steel structure for support, further improving the safety of the temporary water tank at the feeding port. If excessive temperature occurs during the kiln firing process, causing the chain of the first-direction water tank to break, the second-direction water tank can still bear at least part of the load from the first-direction water tank, limiting its further downward movement and thus reducing the risk of water tank falling and related safety accidents. Simultaneously, the second-direction water tank is located precisely at the point where the broken glass is fed, further dissipating heat from the feeding port and lowering the ambient temperature, ensuring the safe operation of the kiln firing process. This temporary water tank device for the feeding port is particularly important for stabilizing the kiln firing process in large-tonnage glass melting furnaces with wide feeding ports.

[0020] Preferably, in one embodiment of this application, the first directional water jacket and the second directional water jacket each include a foldback tube body;

[0021] The zigzag pipe body includes at least two adjacent straight pipe sections and a turning connection section connecting the ends of the two adjacent straight pipe sections. The straight pipe sections and the turning connection section together form a continuous circulating water channel.

[0022] The inlet pipe and outlet pipe are connected to the inlet and outlet ends of the circulating water channel, respectively.

[0023] Preferably, in one embodiment of this application, the first directional water tank and the second directional water tank are connected in parallel to the water supply main and the return main through independent inlet and outlet branches, respectively;

[0024] At least one of the inlet and outlet branches corresponding to each water bag is equipped with a regulating valve, and each first-direction water bag and each second-direction water bag can independently regulate or cut off the circulating water flow through the corresponding regulating valve.

[0025] Both the inlet and outlet pipes include flexible hose sections.

[0026] Preferably, in one embodiment of this application, the suspension assembly includes a chain and a hook, the hook being connected to a first-direction water tank, one end of the chain being connected to the hook, and the other end being connected to a lifting mechanism;

[0027] Each first-direction water bag is provided with at least two suspension components spaced apart along its length. The lifting mechanism is used to drive the first-direction water bag to move between the working position at the feeding port and the disassembly position at the feeding port.

[0028] Preferably, in one embodiment of this application, the bearing structure includes a steel support structure fixedly connected to the top iron of the feeding port, and the second direction water tank is fixed to the steel support structure;

[0029] The steel support structure restricts the movement of the second directional water tank in both the vertical and horizontal directions, so that the second directional water tank remains below the first directional water tank.

[0030] Preferably, in one embodiment of this application, the projections of a plurality of first-direction water bags in the width direction of the feeding port are sequentially adjacent or partially overlapping, and the union of the projections of the plurality of first-direction water bags in the width direction of the feeding port covers the entire width of the feeding port.

[0031] Preferably, in one embodiment of this application, it further includes a flow detection element, a temperature detection element, and a controller;

[0032] Flow detection devices are installed in each inlet branch to detect the inlet flow rate of the corresponding first-direction water bag or second-direction water bag;

[0033] Temperature sensors are installed in each water outlet branch to detect the water temperature of the corresponding first-direction water bag or second-direction water bag;

[0034] The controller is connected to the flow sensor, temperature sensor and regulating valve respectively, and controls the corresponding regulating valve according to at least one of the inlet water flow and outlet water temperature.

[0035] Preferably, in one embodiment of the present invention, the hooks and chains are evenly distributed to bear the load of the water tank.

[0036] Preferably, in one embodiment of the present invention, the steel support structure is fixedly connected to the top iron of the feeding port, and the second-direction water tank is detachably fixed to the steel support structure.

[0037] Preferably, in one embodiment of the present invention, the length of the first directional water bag is about half the width of the feeding port, and the total length of the multiple transverse water bags can completely cover the feeding port.

[0038] Preferably, in one embodiment of the present invention, the length of the second directional water bag needs to be slightly greater than the distance from the foremost end of the feed port to the transverse water bag.

[0039] Preferably, in one embodiment of the present invention, the first directional water jacket and the second directional water jacket are made of carbon steel or stainless steel, etc.

[0040] Preferably, in one embodiment of the present invention, the water pipes of the first direction water jacket and the second direction water jacket are circular steel pipes or rectangular steel pipes.

[0041] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0042] Compared with the prior art, the technical solution of the present invention has achieved the following technical advancements:

[0043] 1. To address the issue that the first directional water tank relies primarily on the suspension components for support and lacks a secondary load-bearing path when the suspension components malfunction, a second directional water tank is installed below the first directional water tank. Under normal suspension conditions, the two water tanks maintain a preset gap. When the first directional water tank malfunctions and the preset gap disappears, they come into contact to form a support. Simultaneously, the predetermined support position is set between two adjacent suspension components. Therefore, under normal conditions, the second directional water tank is prevented from continuously pressing against the first directional water tank. Under malfunction conditions, a secondary load transfer path is established from the first directional water tank, the second directional water tank, to the load-bearing structure, limiting the further descent of the first directional water tank and reducing the risk of falling.

[0044] 2. In order to solve the problem of insufficient cooling coverage of the front end of the feeding port and the area where broken glass falls due to the single cooling direction of the existing transverse water jacket, a method is adopted to set up a first directional water jacket along the width direction of the feeding port and a second directional water jacket along the depth direction of the feeding port. The two sets of water jackets cover different areas of the feeding port respectively, which overcomes the defect that a single directional water jacket cannot cover both the width area and the front end area of ​​the feeding port. This achieves the technical effect of expanding the cooling coverage of the circulating water and reducing the local weak cooling areas.

[0045] 3. In order to solve the problems of large weight, large span and difficult installation and disassembly of water tank when using a single long water tank for wide feeding ports, multiple water tanks in the first direction are arranged in sections, and the coverage of multiple water tanks in the first direction is combined to cover the width of the feeding port. This overcomes the defect that the size and weight of a single water tank increases with the width of the feeding port, and achieves the technical effect of distributing the load of the water tank, reducing the manufacturing and hoisting difficulty of a single water tank, and facilitating the segmented disassembly and replacement.

[0046] 4. In order to solve the problems of difficulty in controlling the flow rate separately, and difficulty in identifying local blockages or water outages when multiple water tanks share a water circuit, each first-direction water tank and second-direction water tank is connected to the main pipeline through inlet and outlet pipes respectively. Regulating valves, flow detection devices and temperature detection devices are installed in the corresponding branches. This overcomes the defects of mutual influence between cooling branches and the inability to independently judge the operating status, and achieves the technical effect of regulating the water supply, cutting off branches and monitoring the operating status of different water tanks separately.

[0047] 5. In order to solve the problems of large amount of manual operation and unstable movement when the temporary water tank is removed from the feeding port after the kiln is baked, hooks and iron chains are used to connect the first direction water tank to the winch, and multiple suspension positions are set along the length of the first direction water tank. This overcomes the defects of concentrated load on single-point suspension and inconvenience of dismantling the fixed installation method, and achieves the technical effect of dispersing the suspension load and enabling the first direction water tank to move between the working position and the dismantling position.

[0060] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0061] In the description of this invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0062] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0063] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0064] The existing temporary water tanks still have certain limitations in terms of installation, removal and flow regulation; when the water flow distribution between different water tanks is uneven or local blockage occurs, the cooling effect may decrease, and it is difficult for on-site personnel to detect and deal with it in time, affecting the stability of the kiln firing process.

[0065] Therefore, it is necessary to improve the support structure and cooling arrangement of the temporary water tank device at the feeding port. While improving the cooling coverage capacity, it is also necessary to improve the load-bearing stability and safety under fault conditions of the water tank, and take into account the convenience of installation, disassembly, flow regulation and maintenance operations. This will reduce the temperature in the feeding port area, reduce the risk of water tank deformation or falling off, and ensure the stable operation of the glass melting furnace baking process.

[0066] like Figure 1-4 As shown, a temporary water jacket device for the feeding port of a glass melting furnace is installed at the feeding port of the glass melting furnace to reduce the temperature at the feeding port during furnace firing. It includes a first-direction water jacket 11, a second-direction water jacket 12, an inlet pipe 2, an outlet pipe 3, and a suspension assembly.

[0067] A first circulating water channel is formed inside the first directional water tank 11. The first directional water tank 11 extends along the width direction of the feeding port and is suspended at the feeding port by at least two suspension components spaced apart along its length direction.

[0068] The second direction water tank 12 forms a second circulating water channel inside. The second direction water tank 12 extends along the depth direction of the feeding port and is fixed to the bearing structure of the feeding port.

[0069] The inlet pipe 2 is connected to the first circulating water channel, the second circulating water channel and the main water supply pipe respectively, and the outlet pipe 3 is connected to the first circulating water channel, the second circulating water channel and the return water main pipe respectively.

[0070] The second directional water tank 12 is located below the first directional water tank 11. One end of the second directional water tank 12 extends to the front end area of ​​the feeding port away from the inside of the kiln, and the other end extends to the vertical projection area of ​​the first directional water tank 11, so that the second directional water tank 12 passes through the feeding area and below the first directional water tank 11 at the same time.

[0071] When the suspension assembly is under normal load and the first directional water bag 11 is in the working position, there is a preset gap between the upper part of the second directional water bag 12 and the lower part of the first directional water bag 11; when the first directional water bag 11 moves downward relative to the working position until the preset gap disappears, the lower part of the first directional water bag 11 contacts the upper part of the second directional water bag 12 and forms a supporting fit, so that at least part of the load of the first directional water bag 11 is transferred to the bearing structure through the second directional water bag 12, and the first directional water bag 11 is restricted from continuing to move downward.

[0072] The preset gap is set such that when the first direction water tank 11 is in normal working condition and generates normal thermal deformation, suspension position fluctuation or installation deviation, the two water tanks do not make load-bearing contact; when the first direction water tank 11 moves abnormally downward, the two water tanks can form a support before the first direction water tank 11 reaches the allowable downward limit.

[0073] In the first direction water tank 11, the supporting position is located between two adjacent suspension components along the length direction. In order to solve the problem that the first direction water tank 11 forms a large suspended span between adjacent suspension points and is prone to downward deflection under its own weight and high temperature, the supporting position of the second direction water tank 12 and the first direction water tank 11 is set between two adjacent suspension components. This overcomes the defect that the lower support and the suspension support position coincide and cannot effectively improve the mid-span force. It achieves the technical effect of providing auxiliary support for the mid-span area of ​​the first direction water tank 11, reducing the maximum bending moment and limiting abnormal downward displacement.

[0074] During implementation, the support position can be set in the middle between adjacent suspension points or near the area with large deflection, and it should be ensured that the two water tanks maintain a preset gap under normal working conditions. High temperature resistant pads, arc-shaped supports or limiting parts can be added to the support part to reduce local contact stress and relative slippage.

[0075] When implementing this application, the key points are as follows: Based on the width, depth, and surrounding steel structure layout of the glass melting furnace feeding port, determine the quantity, length, and installation position of the first directional water tank 11 and the second directional water tank 12; the first directional water tank 11 is suspended along the width direction of the feeding port and connected to the lifting mechanism through at least two suspension components spaced apart along its length direction to ensure uniform force distribution and facilitate installation and removal; the second directional water tank 12 is arranged along the depth direction of the feeding port, with its lower part or side fixed to the bearing structure of the feeding port, and its upper part located below the first directional water tank 11 and forming a flexible space support relationship with the first directional water tank 11 with a preset gap;

[0076] The working principle of this application is as follows: After the kiln firing begins, cooling water enters the first circulating water channel of the first directional water tank 11 and the second circulating water channel of the second directional water tank 12 through the main water supply pipe and the inlet pipe 2, respectively, and flows continuously along the corresponding channels, absorbing the heat radiated by the steel structure and kiln body near the feeding port and transferred by the high-temperature airflow. Then, it is discharged from the main return water pipe through the outlet pipe 3, thus forming a continuous circulating cooling. The first directional water tank 11 mainly cools the high-temperature area within the width range of the feeding port, while the second directional water tank 12 extends along the depth direction of the feeding port to supplement the cooling of the front end of the feeding port and the material falling area. This design allows the two sets of water jackets to form a cross-distributed cooling range, reducing localized insufficient cooling. Simultaneously, the second-direction water jacket 12 is fixed to the load-bearing structure and located below the first-direction water jacket 11. When the suspension assembly is under normal load, a preset gap is maintained between the second-direction water jacket and the first-direction water jacket, and the second-direction water jacket does not bear the normal load of the first-direction water jacket. When the suspension assembly becomes loose, breaks, or the first-direction water jacket abnormally moves downward until the preset gap disappears, the two come into contact to form a support, allowing at least part of the load of the first-direction water jacket to be transferred to the load-bearing structure through the second-direction water jacket, thereby limiting the continued downward displacement of the first-direction water jacket.

[0077] When the suspension assembly becomes loose, breaks, or the first direction water tank 11 moves abnormally downward, the second direction water tank 12 can limit its continued downward movement to prevent the water tank from falling off. After the kiln is finished, the circulating water supply is stopped and the water in the water tank is drained. The first direction water tank 11 is moved out of the feeding port by the lifting mechanism, and then the second direction water tank 12 is removed to restore the normal feeding conditions of the feeding port.

[0078] Specifically, in one embodiment of this application, there are multiple first-direction water bags 11 and multiple second-direction water bags 12;

[0079] Multiple first-direction water bags 11 are arranged sequentially along the first direction, and multiple second-direction water bags 12 are arranged at intervals along the first direction. Each second-direction water bag 12 extends along the second direction and is arranged to correspond to at least one first-direction water bag 11, so that when the corresponding first-direction water bag 11 moves downward to the point where the preset gap disappears, it forms a supporting cooperation with the first-direction water bag 11.

[0080] The first direction is the width direction of the feeding port, and the second direction is the depth direction of the feeding port. The first direction is perpendicular to the second direction.

[0081] To address the issues of large span, concentrated local stress, and uneven cooling coverage when using a single long water bag for a wide feed inlet, multiple first-direction water bags 11 are used to segmentally cover the width of the feed inlet. Multiple second-direction water bags, spaced apart along the first direction, are respectively positioned to support the first-direction water bags at predetermined locations. When the corresponding first-direction water bag abnormally moves downward to the point where the preset gap disappears, it forms a support, thereby dispersing the abnormal load and limiting the continued downward movement of the first-direction water bag.

[0082] During implementation, each first-direction water tank 11 can be adjacent to each other or a gap can be maintained to meet the requirements of thermal expansion and contraction and installation error. The number and spacing of each second-direction water tank 12 can be determined according to the length, weight and feeding port structure of the first-direction water tank 11. In addition to being perpendicular, the first and second directions can also be arranged in an approximately perpendicular cross arrangement, provided that they can form a cross support and cover the corresponding area.

[0083] Specifically, in one embodiment of this application, the first directional water jacket 11 and the second directional water jacket 12 each include a foldback tube body;

[0084] The zigzag pipe body includes at least two adjacent straight pipe sections and a turning connection section connecting the ends of the two adjacent straight pipe sections. The straight pipe sections and the turning connection section together form a continuous circulating water channel.

[0085] Water inlet pipe 2 and water outlet pipe 3 are respectively connected to the water inlet end and water outlet end of the circulating water channel;

[0086] To address the issues of limited heat exchange area and short residence path of cooling water in a straight single-channel water jacket, a zigzag pipe body composed of multiple straight pipe sections and turning connection sections is adopted. This allows the cooling water to flow along a continuous zigzag path, overcoming the defects of insufficient flow channel length and inadequate heat exchange area coverage within the limited installation space. This achieves the technical effects of extending the cooling water flow path, increasing the effective heat exchange area, and improving the overall cooling capacity of the water jacket.

[0087] During implementation, the turning connection section should be sealed and connected to the adjacent straight pipe section, and the sudden cross section and local dead water area should be minimized. The reversible pipe body can be replaced by a welded structure of bent pipe or elbow or a reciprocating box flow channel formed by partition, as long as a continuous circulating water channel from the inlet end to the outlet end can be formed.

[0088] Specifically, in one embodiment of this application, the first directional water tank 11 and the second directional water tank 12 are connected in parallel to the water supply main and the return main through independent inlet and outlet branches, respectively.

[0089] At least one of the inlet branch and outlet branch corresponding to each water bag is equipped with a regulating valve, and each first direction water bag 11 and each second direction water bag 12 can independently regulate or cut off the circulating water flow through the corresponding regulating valve.

[0090] Both the inlet pipe 2 and the outlet pipe 3 include flexible hose sections;

[0091] To address the issues of mutual interference, partial blockage affecting overall water supply, and the inability to independently maintain individual water tanks when multiple water tanks share a series water circuit, a system is designed where each water tank is connected in parallel to the main water supply and return pipes via independent inlet and outlet branches. Regulating valves are installed on the corresponding branches. This overcomes the shortcomings of not being able to control the flow rate of each water tank individually and not being able to isolate faulty branches. The system achieves the technical benefits of independently adjusting the cooling capacity of each water tank, quickly cutting off abnormal branches, and maintaining the continued operation of the remaining water tanks. Flexible hose sections are used to compensate for displacement caused by water tank hoisting, position adjustment, and thermal expansion and contraction.

[0092] During implementation, hoses that are temperature and pressure resistant and compatible with the cooling medium should be selected, and excessive bending or contact with high-temperature components should be avoided. The regulating valve can be a manual valve, an electric regulating valve, or a pneumatic regulating valve. The hose section can also be replaced by a metal bellows or a flexible joint with displacement compensation capability.

[0093] Specifically, in one embodiment of this application, the suspension assembly includes a chain 4 and a hook 5. The hook 5 is connected to the first direction water tank 11, one end of the chain 4 is connected to the hook 5, and the other end is connected to the lifting mechanism.

[0094] Each first-direction water bag 11 is provided with at least two suspension components that are spaced apart along its length. The lifting mechanism is used to drive the first-direction water bag 11 to move between the working position at the feeding port and the disassembly position at the feeding port.

[0095] To address the problems of inconvenient installation and disassembly of the first-direction water tank 11, and the tendency of single-point suspension to generate concentrated loads and unstable posture, at least two iron chains 4 and hooks 5 spaced apart along the length of the water tank are used to connect with the lifting mechanism. This overcomes the shortcomings of fixed installation, which makes it difficult to remove the water tank from the feeding port, and the tendency of the water tank to tilt or fall after the failure of a single suspension point. It achieves the technical effects of dispersing the suspension load, maintaining the balance of water tank lifting and lowering, and facilitating the switching between the working position and the disassembly position.

[0096] During implementation, each suspension point should be arranged in accordance with the center of gravity of the water tank and the load distribution under full water conditions. The lifting mechanism should synchronously pull each chain 4. A reliable anti-detachment structure should be set at the connection between the hook 5 and the water tank. The chains and hooks can also be replaced by wire ropes, slings, lifting lugs, shackles or other flexible suspension components with corresponding load-bearing capacity. The lifting mechanism can be a winch, hand hoist or electric hoist.

[0097] Specifically, in one embodiment of this application, the bearing structure includes a steel support structure fixedly connected to the top iron of the feeding port, and the second direction water tank 12 is fixed to the steel support structure;

[0098] The steel support structure restricts the movement of the second direction water tank 12 in the vertical and horizontal directions so that the second direction water tank 12 remains below the first direction water tank 11;

[0099] To address the issues of the second-direction water tank 12 lacking reliable positioning and being prone to vertical sinking and horizontal displacement under supporting loads or pipeline forces, a steel support structure fixedly connected to the top iron of the feeding port is adopted to limit the vertical and horizontal positioning of the second-direction water tank 12. This overcomes the defects caused by unstable support due to relying solely on pipelines or simple overlapping positioning, and achieves the technical effect of maintaining the stable installation position of the second-direction water tank 12, reliably bearing the load transmitted by the first-direction water tank 11, and maintaining the cross-support relationship.

[0100] During implementation, the steel support structure should avoid the feeding channel and the equipment movement area, and the strength should be determined according to the weight of the full water tank and the impact load that it may bear. In addition to welding, the fixing method can also adopt bolt connection, clamp connection, plug-in support or a combination of welding and detachable connection to facilitate subsequent maintenance and dismantling.

[0101] Specifically, in one embodiment of this application, the projections of multiple first-direction water bags 11 in the width direction of the feeding port are sequentially adjacent or partially overlapping, and the union of the projections of multiple first-direction water bags 11 in the width direction of the feeding port covers the entire width of the feeding port.

[0102] To address the issue of cooling gaps easily forming between segmented first-direction water tanks 11, leading to excessively high local temperatures at the feeding port, the projections of each first-direction water tank 11 in the width direction of the feeding port are sequentially adjacent or partially overlapped, and their projections are combined to cover the entire width of the feeding port. This overcomes the defects of coverage discontinuities and cooling blind spots caused by segmented arrangement, and achieves the technical effect of forming a continuous cooling area along the width direction of the feeding port and improving the uniformity of temperature distribution.

[0103] Specifically, in one embodiment of this application, in order to solve the problem that the front end of the feeding port and the area where broken glass falls are far from the first direction water bag 11 and that a single transverse cooling structure is difficult to cover this area, a second direction water bag 12 is adopted, which extends from the front end area of ​​the feeding port to the vertical projection area of ​​the first direction water bag 11. This overcomes the defects of the cooling area and the supporting area being separated and the same component having a single function, and achieves the technical effect of using the same second direction water bag 12 to simultaneously cool the feeding area and support the first direction water bag 11.

[0104] During implementation, the length of the second-direction water tank 12 should ensure that its front end covers the main high-temperature or feeding area, and that its rear end has sufficient support overlap length. At the same time, it should avoid hindering the installation and operation of the feeding machine, flame baffle components and other equipment. Its extension direction can be adjusted to be straight, broken, or partially curved according to the actual shape of the feeding port.

[0105] Specifically, in one embodiment of this application, it further includes a flow detection element, a temperature detection element, and a controller;

[0106] Flow detection devices are installed in each water inlet branch to detect the inlet flow rate of the corresponding first direction water bag 11 or second direction water bag 12;

[0107] Temperature sensors are installed in each water outlet branch to detect the water outlet temperature of the corresponding first-direction water tank 11 or second-direction water tank 12.

[0108] The controller is connected to the flow sensor, temperature sensor and regulating valve respectively, and controls the corresponding regulating valve according to at least one of the inlet water flow and outlet water temperature.

[0109] To address the challenges of timely detection of water outages, insufficient flow, or internal blockages in the water jacket branch circuits, and the difficulty in accurately matching actual cooling demands with manual adjustments, a flow detection device is used to monitor the water supply status of each inlet branch circuit, and a temperature detection device is used to monitor the return water temperature of each outlet branch circuit. The controller then controls the corresponding regulating valves based on the detection results. This overcomes the deficiency of lacking independent monitoring and adjustment data for the water jacket's operating status, and achieves the technical effect of identifying abnormal water outages, excessive or insufficient heat exchange, and automatically adjusting the cooling water flow rate according to the branch circuit.

[0110] During implementation, the minimum flow rate, maximum outlet water temperature, and corresponding alarm or adjustment logic can be preset. When the detected value exceeds the set range, the controller increases the valve opening, issues an alarm, or cuts off the abnormal branch. The flow detection device can be a flow meter, flow switch, or differential pressure detection device. The temperature detection device can be a thermocouple, resistance temperature detector, or other sensor suitable for pipeline temperature detection. The controller can be implemented by DCS, PLC, or independent control module.

[0111] Specifically, in one embodiment of this application, the hooks and chains should be evenly distributed to bear the load of the water tank;

[0112] The steel support structure is fixed to the top iron of the feeding port by welding or bolting, and the second direction water tank is detachably fixed to the steel support structure by clamps, bolts or plug-in structure.

[0113] The length of each first-direction water tank is about half the width of the feed inlet, and the total length of multiple transverse water tanks can completely cover the feed inlet; the length of each second-direction water tank needs to be slightly greater than the distance from the front end of the feed inlet to the transverse water tank; the material of each first-direction water tank and the second-direction water tank is carbon steel or stainless steel, etc.; the water pipe of each first-direction water tank and the second-direction water tank is a round steel pipe or a rectangular steel pipe.

[0114] Hooks and chains should be evenly installed according to the center of gravity and load distribution of the first-direction water tank 11 when it is full of water, to avoid overloading of local suspension points and tilting of the water tank during lifting and lowering. When the second-direction water tank 12 is fixed to the top iron of the feeding port through a steel structure, it should be ensured that the welded parts have sufficient load-bearing strength and that the heat effect of welding should be avoided from adversely affecting the top iron or adjacent components. If necessary, a detachable bracket can be used as a substitute. The length of the first-direction water tank 11 is set to about half the width of the feeding port, which can control the weight and lifting size of a single water tank while ensuring that multiple water tanks cover the feeding port together. Its specific length can be adjusted according to the width of the feeding port, the load-bearing capacity of the winch, and the disassembly space on site. The length of the second-direction water tank 12 is slightly greater than the distance between the front end of the feeding port and the first-direction water tank 11, so as to ensure that it covers the front cooling area and the lower support area at the same time, and a length margin should be reserved to meet the requirements of installation deviation and thermal expansion.

[0115] The first directional water jacket 11 and the second directional water jacket 12 can be made of carbon steel, stainless steel or other metal materials with corresponding temperature resistance and corrosion resistance, depending on the operating temperature, cooling water quality and service cycle. The cross-section of the pipe can be circular, rectangular, elliptical or other cross-sectional forms that can form a closed circulating water channel and meet the structural strength requirements.

[0116] Specifically, in one embodiment of this application, such as Figure 1-4 As shown, a temporary water tank device for the feeding port of a glass melting furnace includes a first-direction water tank 11, a second-direction water tank 12, a water outlet pipe 3, an iron chain 4, and a hook 5; one end of the water inlet pipe 2 is connected to the water tank, and the other end is connected to the main water inlet pipe.

[0117] One end of the water outlet pipe 3 is connected to the water tank, and the other end is connected to the main water pipe; the first direction water tank 11 and the second direction water tank 12 are set perpendicularly. The first direction water tank 11 is mainly used to cool the width range of the feeding port, and the second direction water tank 12 plays a role in cooling and supporting the first direction water tank 11, thereby reducing the temperature inside the feeding port.

[0118] A flow switch is installed on the inlet pipe to monitor the water supply interruption of the water tank, and a temperature sensor is installed on the return pipe. The flow switch and temperature sensor are transmitted to the DCS system via signal lines. The system determines whether the cooling water flow of the corresponding water tank needs to be increased based on the return water temperature, and determines whether there is a blockage in the corresponding water tank by combining the opening of the regulating valve and the inlet water flow.

[0119] The flow detection device and temperature detection device send the inlet water flow signal and the outlet water temperature signal to the DCS system, respectively. The DCS system controls the regulating valve on the corresponding inlet or outlet branch according to the inlet water flow and outlet water temperature. When the opening of the regulating valve increases, if the flow of the corresponding branch is still lower than the set value, the DCS system can determine that there may be a blockage in the branch and issue an alarm.

[0120] The first direction water tank 11 and the second direction water tank 12 are made of cold-drawn seamless steel pipe or stainless steel pipe of Q235-A material.

[0121] Before the kiln enters the formal production stage, first remove half of the ceramic fiber cover plate on the feeding port, raise a set of temporary first direction water tanks 11, and pay attention to using a shovel to hold the water tanks in place to prevent them from shifting outwards when raising them. After the water tanks are raised to a certain height, pull out the feeding port. After the water tanks are pulled out, remove the supporting second direction water tanks 12. After the water tanks are removed, lower the flame baffle bricks to the lower edge of the L hanging wall, remove the sealing bricks of the south feeding port, and then push in the feeding machine on one side.

[0122] In summary, this invention solves the problem of water tank support being prone to breakage and unstable support during the previous use of water tanks by setting up multiple first-direction water tanks 11 and second-direction water tanks 12 for cooling the cooling section. Therefore, this device can use the existing top iron or steel structure of the feeding port as the installation base without changing the overall layout of the main steel structure of the feeding port, thus overcoming the instability problem during the kiln firing process and having great practical value.

[0123] Specifically, in one embodiment of this application, a temporary water jacket device for the feeding port of a glass melting furnace is provided to solve the problems of limited cooling coverage, insufficient suspension bearing stability, and inconvenience in installation, disassembly, and water flow adjustment of existing temporary water jackets.

[0124] The temporary water tank device is installed at the feeding port of the glass melting furnace and includes a first-direction water tank, a second-direction water tank, an inlet pipe, an outlet pipe, an iron chain, and hooks. The first-direction water tank is arranged along the width direction of the feeding port and is connected to the winch via hooks and iron chains. The second-direction water tank is located below the first-direction water tank along the depth direction of the feeding port and is fixed to the supporting structure of the feeding port. The first-direction water tank and the second-direction water tank respectively form a circulating water channel, and the circulating water enters the water tank through the inlet pipe and is discharged through the outlet pipe.

[0125] By arranging the first and second directional water bags in a cross pattern, the first directional water bag is used to cover the width of the feeding port, while the second directional water bag is used to cool the front end of the feeding port and the area where the material falls, and also provides auxiliary support for the first directional water bag. In this way, while expanding the cooling coverage area, the risk of deformation or downward movement of the first directional water bag due to abnormal span, weight, or suspension components is reduced, and it is also convenient to independently adjust the water supply, hoist, and disassemble each water bag.

[0126] Specifically, in one embodiment of this application, when the first directional water bag 11 is in the normal suspension position, its weight is mainly borne by the suspension components spaced apart along the length direction. A preset gap is left between the upper part of the second directional water bag 12 and the lower part of the first directional water bag 11, so the second directional water bag 12 does not continuously press against the first directional water bag 11.

[0127] When the suspension assembly becomes loose or breaks, or when the first direction water tank 11 moves downward for other reasons, the preset gap gradually decreases until it disappears. The lower part of the first direction water tank 11 contacts the upper part of the second direction water tank 12, so that part of the load of the first direction water tank 11 is transferred to the bearing structure of the feeding port through the second direction water tank 12, thereby restricting the first direction water tank 11 from continuing to move downward.

[0128] The second directional water tank 12 and the first directional water tank 11 are located between two adjacent suspension components, so that the second directional water tank 12 can provide lower support for the area of ​​the first directional water tank 11 located between adjacent suspension positions. At the same time, the second directional water tank 12 extends from the front end area of ​​the feeding port to the bottom of the first directional water tank 11. When the circulating cooling water flows through the second directional water tank 12, it can cool the feeding area. Therefore, the same second directional water tank 12 simultaneously constitutes a cooling component for the feeding area and a support component when the first directional water tank 11 moves abnormally downward, without the need to set up a separate support beam.

[0129] In summary, this invention aims to solve the problem that the temperature in the feeding port area is high during the firing process of glass melting furnaces, and the existing temporary water tanks have a single cooling direction and the support structure mainly relies on iron chains and hooks for suspension, which makes the water tanks prone to deformation, downward movement or suspension failure under their own weight, high temperature and continuous load. At the same time, it also solves the problems of large size of individual water tanks, difficulty in hoisting and inability to independently adjust the water flow of different water tanks under wide feeding port conditions.

[0130] To address this, the present invention provides a first directional water tank 11 and a second directional water tank 12 at the feeding port. The first directional water tank 11 extends along the width of the feeding port and is connected to a winch via a hook 5 and a chain 4. It is used to cool the width range of the feeding port and can be driven out of the feeding port by the winch after the kiln is finished. The second directional water tank 12 is located below the first directional water tank 11 along the depth of the feeding port. One end of the second directional water tank 12 extends to the front end area of ​​the feeding port, and the other end extends below the first directional water tank 11. While cooling the front end of the feeding port and the area where broken glass falls, the second directional water tank 12 also provides auxiliary support for the first directional water tank 11, thereby reducing the bending span of the first directional water tank 11 and restricting the first directional water tank 11 from continuing to move downward when the suspension structure malfunctions.

[0131] Both the first directional water tank 11 and the second directional water tank 12 are equipped with circulating water channels and are connected to the main water supply pipe and the main water return pipe respectively through the corresponding inlet pipe 2 and outlet pipe 3; each water tank can adopt independent parallel branches and a regulating valve is installed on the branch to allow the water flow of each water tank to be regulated or cut off separately; after further setting flow detection devices and temperature detection devices, the water supply status and heat exchange status of each water tank can be judged according to the inlet water flow and outlet water temperature;

[0132] Through the above structure, the water jacket device forms a cooling zone distributed along the width and depth of the feeding port, and forms a support relationship that combines suspension bearing and lower support, thereby taking into account the requirements of feeding port cooling, structural bearing, water channel adjustment and installation and disassembly.

[0133] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
