[0035] Reference Figure 1-3 , introduces a smoke guide device that is easy to clean according to the present application.
[0036] The smoke guide device according to this embodiment includes a plurality of linearly arranged smoke guide holes, which are connected by a cleaning assembly to facilitate water injection into the water seal groove 2 of the smoke guide hole, thereby achieving the purpose of water sealing or cleaning;
[0037] The smoke guide hole includes a smoke guide hole seat 1 and a smoke guide hole cover arranged on the smoke guide hole seat 1. The smoke guide hole seat 1 is provided with a water seal groove 2 and a first mounting frame 3. The water seal groove 2 is arranged around the outer side of the smoke guide hole cover, which reduces the heat lost to the atmosphere and prevents impurities carried by the smoke from entering the atmosphere, thereby saving energy and protecting the environment. A second mounting frame 4 is arranged on the side of the water seal groove 2 away from the smoke guide hole cover. The second mounting frame 4 is located above the first mounting frame 3, and the layout is reasonable, which is conducive to injecting water into the water seal groove 2 and discharging water in the water seal groove 2 in time.
[0038] The cleaning assembly includes a water inlet pipe 5, a drain pipe 6 and a drain trough 7. The water inlet pipe 5 is installed on the second mounting frame 4 to facilitate the injection of clean water into the water seal trough 2. The drain trough 7 is installed on the first mounting frame 3. The water seal trough 2 and the drain trough 7 are connected through the drain pipe 6 to facilitate the timely discharge of sewage in the water seal trough 2.
[0039] A plurality of water inlet branch pipes 8 are arranged on the water inlet pipe 5, and the plurality of water inlet branch pipes 8 are connected one by one with the water seal grooves 2 on the plurality of smoke guide holes. In this way, a water seal groove 2 of a smoke guide hole corresponds to a water inlet branch pipe 8. When water is injected into the water seal groove 2 of one of the smoke guide holes, the water inlet branch pipes 8 corresponding to the water seal groove 2 of the smoke guide holes in the same group of water inlet pipes 5 are in a closed state, and therefore will not be affected by the backflow sewage, thereby ensuring normal production operation.
[0040] As an embodiment, the smoke duct cover includes a top cover 9 and a bottom cover 10. A threaded column 11 extends from the lower end of the top cover 9. The top cover 9 and the bottom cover 10 are connected by the threaded column 11, which is convenient for disassembly and assembly and facilitates maintenance, especially for replacing the insulation net 12 between the two.
[0041] As an implementation mode, a cavity is surrounded by the top cover 9 and the bottom cover 10, and a heat insulation net 12 is arranged in the cavity to enhance the heat insulation effect of the smoke guide hole cover, reduce heat transfer to the atmosphere through the smoke guide hole, and achieve the purpose of energy saving and consumption reduction.
[0042] Optionally, the insulation net 12 is aluminum silicate fiber felt, which has excellent high temperature resistance and a maximum operating temperature of 1300°C. At the same time, it has low thermal conductivity and good insulation performance. When used under the same conditions, the thermal conductivity of aluminum silicate products is more than 30% lower than that of other insulation materials.
[0043] As an implementation mode, a bending portion 13 extends from the outer periphery of the top cover 9, and the cross-section of the bending portion 13 is L-shaped, which facilitates the smoke overflowing from the connecting gap between the smoke guide hole seat 1 and the smoke guide hole cover to enter the water contained in the water seal groove 2, avoiding it from flowing into the atmosphere, thereby saving energy and protecting the environment.
[0044] As an embodiment, the first placement frame 3 includes a bracket 14 and a guide column 15, and the drainage trough 7 is placed on the bracket 14, so that the bracket 14 can move it along the guide column 15;
[0045] An oblong hole 16 is formed on the guide column 15, and a bolt hole 17 is formed on the bracket 14. Bolts pass through the oblong hole 16 and the bolt hole 17 in sequence to connect the guide column 15 and the bracket 14, so as to facilitate the adjustment of the height of the drainage trough 7 to adapt to different working conditions.
[0046] As an implementation mode, the cross-section of the second mounting frame 4 is hook-shaped, and a hook groove 18 is provided at the lower portion of the second mounting frame 4. The water inlet pipe 5 is placed in the hook groove 18 to fix the position of the water inlet pipe 5. The structure is reasonable, easy to use, and is conducive to improving production efficiency.
[0047] As an embodiment, the cleaning component also includes a sewage cleaning plug, which is arranged in the water seal groove 2 to play a sealing or overflow role to ensure the normal use of the water seal groove 2; the sewage cleaning plug includes a first threaded tube 19 and a second threaded tube 20, and the second threaded tube 20 is threadedly connected to the outside of the first threaded tube 19 to facilitate adjusting the height of the sewage cleaning plug, thereby controlling the overflow height of the water, and the side of the first threaded tube 19 away from the second threaded tube 20 is connected to the drain pipe 6, so that the overflowing water can pass through the second threaded tube 20 and the first threaded tube 19 and then enter the drain pipe 6.
[0048] As an implementation mode, a circulating water tank 21 is also provided on the water inlet pipe 5 so that there is always a clean water source in the water inlet pipe 5, thereby realizing the effective use of water resources.
[0049] As an implementation mode, a sewage pool 22 is provided on the drainage trough 7 to facilitate centralized treatment of the received sewage.
[0050] As an implementation method, a ball valve 23 is provided on the water inlet branch pipe 8, which is used to control the water in the water inlet pipe 5 to flow into the water seal groove 2 of the corresponding smoke guide hole through the water inlet branch pipe 8, while avoiding interference with the water in the water seal groove 2 of the remaining smoke guide holes of the same group of water inlet pipes 5, thereby ensuring normal production.
[0051] The working principle of the smoke guide device according to this embodiment is:
[0052] First, pull out the sewage outlet plug in the water seal groove 2 of one of the smoke guide holes, and the sewage passes through the drain pipe 6 and the drain groove 7 in turn and reaches the sewage pool 22 for centralized treatment; then, open the ball valve 23 on the water inlet branch pipe 8 corresponding to the smoke guide hole, and the clean water in the water inlet pipe 5 enters the water seal groove 2 to clean the water seal groove 2. After cleaning, plug the sewage outlet plug back into its original position, and when the water level in the water seal groove 2 is slightly lower than the highest position of the second threaded pipe 20, close the ball valve 23.
[0053] It can be understood that the easy-to-clean smoke guide device can clean the water seal groove 2 of one of the smoke guide holes, and can also clean the water seal grooves 2 of multiple smoke guide holes at the same time, using the same method as above.
[0054] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
[0055] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
