Description

Technical Field

[0001] The utility model relates to the field of energy conservation and environmental protection, in particular to an energy-saving and environmentally friendly smoke exhaust device for a boiler. Background Art

[0002] At present, a Chinese utility model with the announcement number CN212108464U discloses an energy-saving and environmentally friendly smoke exhaust device for a boiler room, including a smoke exhaust pipe body, the top of the smoke exhaust pipe body is rotatably connected to a rotating rod through a bearing, and the bottom of the rotating rod penetrates the smoke exhaust pipe body and extends to the bottom of the smoke exhaust pipe body, the bottom of the rotating rod is fixedly installed with a crank, the middle position of the rotating rod is sleeved inside the water drop sheet, the upper and lower ends of the smoke exhaust pipe body are fixedly installed with fixed blocks, and the left side of the fixed block is fixedly installed with a first spring, the left side of the first spring is fixedly installed at the upper and lower ends of the right side of the cleaning plate, and a filter is arranged inside the smoke exhaust pipe body. This utility model avoids the problem that the dust contained in the smoke will clog the filter when used for a long time, resulting in poor filtering effect and smoke cannot be discharged, reducing the practicality of the device and affecting work efficiency.

[0003] Although the existing smoke exhaust device is equipped with a filter to intercept dust contained in the smoke, there are still other problems during use, such as it is inconvenient to clean the filter. If a cleaning plate equal to the filter is used to push the filter inside the device, although the mesh can be unblocked, the cleaning plate same as the filter will occupy a large area, seriously blocking the limited pipeline space, and it is not convenient to discharge internal impurities to the outside. Impurities in the smoke are intercepted by the filter and accumulate inside the device. When too much internal impurities accumulate, personnel are required to disassemble the device, then remove it for cleaning and reinstall it. The operation is cumbersome and complicated. In order to solve the above-mentioned problems, we propose an energy-saving and environmentally friendly smoke exhaust device for boilers. Utility Model Content

[0009] The utility model is further configured as follows: a support sleeve is sleeved on the surface of the first rotating rod, and a top of the support sleeve is welded to the shell through a fixing piece.

[0010] By adopting the above technical solution, the first rotating rod can be supported by setting the supporting sleeve, thereby improving the stability of the first rotating rod during the rotation process.

[0011] The utility model is further configured as follows: a slide rail is bolted inside the fixing frame, and a sliding block slidably connected to the slide rail is welded on the top of the threaded plate.

[0012] By adopting the above technical solution, the threaded plate can be limited by setting the slide rail and the slider to prevent the threaded plate from rotating during the lateral movement.

[0013] The utility model is further configured as follows: the threaded rod and the threaded plate are both made of stainless steel.

[0014] By adopting the above technical solution, the threaded rod and the threaded plate have the characteristics of high strength, low density and excellent corrosion resistance.

[0015] The utility model is further configured as follows: the shape of the brush body is a rectangle.

[0016] By adopting the above technical solution, the shielding area of ​​the filter can be reduced.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. The utility model fixes the bottom end of the first pipe at the smoke exhaust port of the boiler first, and the smoke generated by the boiler will be discharged outward through the first pipe, the shell and the second pipe in sequence, and the impurities in the smoke can be intercepted by the internal filter. When there are many impurities attached to the surface of the filter, the first handle is held by hand to drive the second rotating rod to rotate. When the second rotating rod rotates, it drives the first rotating rod to rotate through the cooperation of the second bevel gear and the first bevel gear. When the first rotating rod rotates, it drives the brush body to rotate together to scrape off the impurities, which can be convenient for personnel to clean the filter. The operation is simple and convenient, and the smooth flow of internal smoke is guaranteed.

[0019] 2. The utility model allows the user to hold the second handle by hand and rotate it when impurities accumulate inside the device. When the second handle is rotated, it drives the threaded rod to rotate through the cooperation of the bearing. When the threaded rod rotates, it drives the threaded plate to move outward through the cooperation of the slide rail and the slider. When the threaded plate moves outward, it drives the push plate to move outward together with the fixing of the connecting plate and the connecting rod. When the push plate moves outward, it pushes the impurities inside the shell through the opening, which can facilitate the discharge of internal impurities, reduce the burden on personnel to disassemble and assemble the device, improve work efficiency, and has high practicality.
