Description
Technical Field
[0001] This utility model relates to the field of heat storage chamber grids, and in particular to a dredging tool for heat storage chamber grids. Background Technology
[0002] During the production process of a glass kiln, the flue gas produced by combustion carries away a large amount of heat. Before exiting the kiln, this flue gas passes through a regenerator, which is filled with lattice bodies. These lattice bodies are usually made of refractory materials and have high heat capacity and thermal conductivity. When the flue gas passes through the lattice bodies in the regenerator, the lattice body material absorbs the heat from the flue gas. During this process, the temperature of the lattice increases while the temperature of the flue gas decreases. Through this heat exchange, the regenerator accumulates the heat energy in the flue gas and stores it in the material of the lattice. In the operation of the glass furnace, the combustion process is periodically alternating, which is called "fire switching". During fire switching, the gas supply direction of the burner is changed, so that the regenerator, which originally discharged flue gas, is used to preheat the air entering the burner. After fire switching, the cold air is guided through the lattice of the regenerator. At this time, the heat accumulated in the lattice is transferred to the air, causing the air temperature to rise. The preheated air temperature can reach a very high level. When the air enters the burner, the higher the air temperature, the more complete the combustion reaction, thereby releasing more heat.
[0003] However, the flue gas produced by kiln combustion often contains a large amount of dust and particulate matter. These substances will be deposited in the grid of the heat storage body as the flue gas flows. Over time, this accumulation will cause the grid to become blocked. Blockage of the grid reduces the effective contact area between the flue gas and the heat storage body, thereby reducing the heat exchange efficiency. This means that more heat is discharged with the flue gas and is not effectively recovered. To address this problem, operators usually use a cleaning rod to clear the grid. However, clearing the blockage will generate a large amount of dust, which will be dispersed for a long time. In particular, the cleaning rod has a sharp end, which cannot be accurately aimed at the blockage and instead makes incorrect contact with other parts of the grid. This will cause the sharp end to scratch or penetrate the grid material, weakening the structural integrity of the grid. In the long run, this will cause damage or even collapse of the grid. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a tool for unclogging a heat storage chamber grid. The purpose is to solve the problem of generating a large amount of dust during unclogging, which persists for a long time. In particular, the sharp end of the unclogging rod is not accurately aligned with the blockage, instead making incorrect contact with other parts of the grid. This results in scratches or penetration of the grid material, weakening its structural integrity and potentially causing damage or even collapse over time.

[0009] The operator can adjust the position of the unblocking head by sliding the unblocking rod according to the depth of the grid and the location of the blockage.

The exhaust end of the dust collector is connected to the third connection port, which can generate negative pressure suction. The second connection port is connected to the third connection port through a connecting pipe, so that the internal connecting cavity of the unclogging rod is connected to the movable cavity of the support body, thus constructing a complete dust collection system. This allows the unclogging rod to maintain the continuity and stability of the dust collection function when sliding in the movable cavity.
[0012] Furthermore, in this application, the connecting pipe is a flexible hose.

[0018] Furthermore, in this application, a filter groove is provided on the other side of the dust collection box, and a filter screen is provided inside the filter groove.
[0019] This utility model has the following beneficial effects:
[0020] When unblocking, the operator holds the unblocking rod, inserts the pointed end into the clogged grid, and starts the vacuum fan to begin the unblocking operation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0032] As a key component of the heat recovery system in glass furnaces, the regenerator lattice faces severe clogging problems during long-term use. Large amounts of dust and particulate matter carried in the flue gas gradually accumulate in the lattice's gaps, causing narrowing or even complete blockage of airflow channels. This clogging significantly reduces the heat exchange efficiency of the regenerator, preventing the effective recovery of a large amount of heat and directly impacting the energy utilization rate of the entire glass furnace system.
[0033] In the regenerator of a large glass furnace, the lattice structure, constructed of refractory bricks, forms a complex honeycomb structure. Over time, dust from the flue gas gradually accumulates on the lattice surface, forming a 5-10 mm thick layer of deposits. These deposits not only reduce the effective cross-sectional area of the airflow channels but also significantly decrease the heat transfer efficiency between the lattice material and the airflow. Actual measurement data shows that the heat recovery efficiency of a severely clogged regenerator can decrease by more than 40%, directly leading to a substantial increase in the energy consumption required for glass melting. To maintain normal production, operators must frequently use cleaning tools to clear the lattice; however, traditional cleaning methods have many problems and are difficult to effectively solve the blockage issue.
[0034] To address the problem of clogged heat storage chamber lattice, several possible solutions were initially considered. Increasing the pore size of the lattice to reduce dust accumulation would decrease heat exchange efficiency and fail to resolve the existing clog. While high-pressure gas purging could remove dust to some extent, it would cause further dust diffusion, polluting the environment and severely impacting operator visibility. Chemical solvent cleaning might be effective, but it is complex and could introduce new contaminants. After careful consideration, it was realized that a tool capable of both unclogging and cleaning was needed. Therefore, a heat storage chamber lattice unclogging tool integrating unclogging and vacuuming functions was proposed.
[0035] Reference Figures 1-5 In some specific embodiments, a cleaning tool for a heat storage chamber grid includes a cleaning rod 2, a cleaning head 3 at one end of the cleaning rod 2, a sharp part 4 at one end of the cleaning head 3, a suction port 5 on one side of the cleaning head 3, the suction port 5 being close to the sharp part 4, a connecting cavity 7 inside the cleaning rod 2, a first connecting port 29 at one end of the cleaning rod 2, the first connecting port 29 being connected to the connecting cavity 7, the suction port 5 being connected to the first connecting port 29, a vacuum fan 11 at the other end of the cleaning rod 2, a second connecting port 30 at the other end of the cleaning rod 2, the second connecting port 30 being connected to the connecting cavity 7, the exhaust end of the vacuum fan 11 being connected to the second connecting port 30, and a dust collection box 13 at the exhaust end of the vacuum fan 11.
[0036] With the above technical solution, when unblocking, the operator holds the unblocking rod 2, inserts the sharp part 4 into the blocked grid, and starts the vacuum fan 11 to begin the unblocking operation. As the sharp part 4 loosens and breaks up the blockage, the generated dust is immediately sucked away by the suction port 5 and transferred to the dust collection box 13 through the connecting cavity 7. This design not only improves cleaning efficiency but also greatly improves the operating environment, avoids dust from obscuring the operator's unblocking work, ensures the visibility of the operating environment, and avoids scratches or penetration of the grid material.
[0037] The design of the connecting cavity 7 needs to take into account the principles of fluid dynamics to ensure that dust can pass through smoothly. The diameter of the connecting cavity 7 can be gradually increased from the end near the suction port 5 to the end near the suction fan 11. The diameter can be increased from 10 mm to 20 mm. This gradual design can reduce airflow resistance.
[0038] In addition, the other end of the unclogging head 3 is provided with a connecting post 6, and a connecting hole 8 is provided on one side of the connecting post 6. The connecting post 6 is threadedly engaged with the first connecting port 29. The connecting hole 8 is connected to the suction port 5 and the first connecting port 29 respectively. This allows for the replacement of different types of unclogging heads 3 when needed, facilitating cleaning and maintenance. A storage battery 28 is provided on one side of the vacuum blower 11, and the storage battery 28 is electrically connected to the vacuum blower 11.
[0039] Reference Figures 1-6 In some specific embodiments, it also includes a support body 1, the inside of which is provided with a movable cavity 31, the movable cavity 31 passing through one end of the support body 1, the unclogging rod 2 slidingly engaging with the movable cavity 31, the unclogging head 3 protruding from one end of the support body 1, and the vacuum cleaner 11 located at the other end of the support body 1.
[0040] With the above technical solution, when the unblocking begins, the operator holds the support body 1. The operator can adjust the position of the unblocking head 3 by sliding the unblocking rod 2 according to the depth of the grid and the location of the blockage. This makes the length of the unblocking head 3 longer, avoiding direct contact between the operator and the unblocking rod 2, which may contain high temperature or harmful substances. At the same time, it can ensure a certain safe distance from the grid.
[0041] Reference Figures 1-4 In some specific embodiments, the other end of the support body 1 is provided with a third connection port 32, the exhaust end of the dust collector 11 is connected to the third connection port 32, the second connection port 30 is connected to a connecting pipe 9, the connecting pipe 9 is located inside the movable cavity 31, and one end of the connecting pipe 9 is connected to the third connection port 32.
[0042] Through the above technical solution, by opening a third connection port 32 at the other end of the support body 1 and connecting it to the movable cavity 31, a complete dust collection channel is formed. The exhaust end of the dust collection fan 11 is connected to the third connection port 32, which can generate negative pressure suction. The second connection port 30 is connected to the third connection port 32 through the connecting pipe 9, so that the internal connecting cavity 7 of the unclogging rod 2 is connected to the movable cavity 31 of the support body 1, thereby constructing a complete dust collection system. This allows the unclogging rod 2 to maintain the continuity and stability of the dust collection function when sliding in the movable cavity 31.
[0043] Reference Figures 1-4 In some specific implementations, the connecting pipe 9 is a flexible telescopic hose.
[0044] Through the above technical solution, the telescopic hose has the characteristic of being telescopic, and can be extended or shortened when needed, making the connection between the unblocking rod 2 and the support body 1 more flexible. This design can improve the ease of use and operational flexibility of the tool.
[0045] Reference Figures 1-4In some specific embodiments, a plurality of fixing holes 19 are provided on one side of the unblocking rod 2, and a fixing cylinder 20 is provided on one side of the support body 1. The fixing cylinder 20 is connected to the movable cavity 31. A fixing spring 22 is provided inside the fixing cylinder 20. A mounting post 24 is provided at one end of the fixing spring 22. A fixing pin 23 is provided at one end of the mounting post 24. One end of the fixing pin 23 passes through the interior of the fixing cylinder 20 and the interior of the fixing spring 22, so that one end of the fixing pin 23 is inserted into any fixing hole 19. The other end of the mounting post 24 protrudes out of the fixing spring 22.
[0046] With the above technical solution, when it is necessary to adjust the length of the unblocking rod 2, the operator can pull the mounting post 24 to disengage the fixing pin 23 from the fixing hole 19. At this time, the fixing spring 22 is stretched and stores elastic potential energy. The operator can freely slide the unblocking rod 2 to the desired position. When aligned with the new fixing hole 19, the mounting post 24 is released. Under the force of the fixing spring 22, the fixing pin 23 will automatically insert into the fixing hole 19 to complete the position locking. This spring-assisted pin structure not only ensures the reliability of the fixation but also provides a convenient operating experience.
[0047] Reference Figure 6 In some specific embodiments, the fixed cylinder 20 has first locking protrusions 21 on both sides inside, and the first locking protrusions 21 on both sides inside the fixed cylinder 20 are engaged with the other end of the fixed spring 22. The mounting post 24 has second locking protrusions 25 on both sides, and the second locking protrusions 25 on both sides of the mounting post 24 are engaged with one end of the fixed spring 22.
[0048] Through the above technical solution, the first locking protrusions 21 provided on both sides inside the fixed cylinder 20 are engaged with the other end of the fixed spring 22, which can firmly fix the fixed spring 22 inside the fixed cylinder 20 and prevent the fixed spring 22 from shifting or falling off during use. The second locking protrusions 25 provided on both sides of the mounting post 24 are engaged with one end of the fixed spring 22, which can firmly connect the mounting post 24 and the fixed spring 22, ensuring that the fixing pin 23 can be accurately inserted into the fixing hole 19. This structural design not only improves the stability and reliability of the fixing mechanism, but also makes it easier for operators to quickly adjust the position of the unblocking rod 2, thereby improving the efficiency and flexibility of the tool.
[0049] Reference Figure 6 In some specific embodiments, the other end of the mounting column 24 is provided with a pull bracket 26.
[0050] Reference Figures 1-6 In some specific embodiments, a guide groove 16 is provided on one side of the support body 1, the guide groove 16 is connected to the movable cavity 31, a guide slider 17 is provided on one side of the unblocking rod 2, the guide slider 17 is slidably engaged with the guide groove 16, one side of the guide slider 17 protrudes from the guide groove 16, and a pull plate 18 is provided on one side of the guide slider 17.
[0051] Through the above technical solution, the guide groove 16 opened on one side of the support body 1 cooperates with the guide slider 17 on the unblocking rod 2 to guide the unblocking rod 2 to slide smoothly in the movable cavity 31, realizing the stable sliding of the unblocking rod 2 in the support body 1, improving the operating accuracy of the unblocking tool. The setting of the pull plate 18 enhances the operator's control over the unblocking rod 2, making the unblocking process smoother.
[0052] Reference Figure 4 In some specific embodiments, the air outlet of the vacuum blower 11 is connected to a first connecting cylinder 12, and a second connecting cylinder 14 is provided on one side of the dust collection box 13. The outer diameter of the second connecting cylinder 14 is smaller than the inner diameter of the first connecting cylinder 12, and the second connecting cylinder 14 is threadedly engaged with the inner thread of the first connecting cylinder 12.
[0053] Through the above technical solution, by setting a first connecting cylinder 12 at the air outlet of the vacuum fan 11 and a second connecting cylinder 14 on one side of the dust collection box 13, and connecting the two with threads, a reliable connection between the dust collection box 13 and the vacuum fan 11 is achieved. The outer diameter of the second connecting cylinder 14 is smaller than the inner diameter of the first connecting cylinder 12. This design can ensure that the two connecting cylinders can fit tightly to prevent dust leakage. At the same time, the threaded connection method makes the dust collection box 13 easy to disassemble and install, and convenient for cleaning and maintenance.
[0054] Reference Figure 4 In some specific embodiments, a filter groove 10 is provided on the other side of the dust collection box 13, and a filter screen 15 is provided inside the filter groove 10.
[0055] Through the above technical solution, the filter 15 can intercept finer dust particles and prevent them from escaping from the dust collection box 13. This design not only improves the dust collection efficiency, but also ensures that the exhaust air is cleaner.
