Description

Technical Field

[0001] This utility model relates to the field of flue maintenance equipment technology, and in particular to a flue cleaning device. Background Technology

[0002] Currently, in the deep drying process of hazardous waste, most of the flue gas is transported to the dust removal equipment through flue ducts. When the flue gas humidity is high and the flue gas temperature is below the dew point temperature, ash will accumulate in the flue duct. As the operating time increases, the amount of ash accumulated in the flue duct increases. The ash accumulation in the flue duct will affect the ventilation of the flue duct system (the flue duct is connected to the flue gas purification equipment, and an induced draft fan is usually installed at the purification equipment to provide power so that the flue gas can be smoothly transported to the purification equipment for purification), increase the ventilation resistance of the flue duct system, and thus cause problems in the deep drying system. In order to ensure smooth and efficient production, it is necessary to shut down the furnace for cooling and manually open the vents so that cleaning personnel can enter the flue duct for manual cleaning. Shutting down and starting the furnace not only increases the production and operating costs, but the waiting time for cooling down the furnace also increases the time cost. Manual entry into the flue duct is a closed space operation and poses certain safety hazards. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the present invention provides a flue cleaning device, which solves the problems of long time consumption, low efficiency and safety hazards in the existing flue cleaning technology.

[0004] According to an embodiment of the present invention, a flue cleaning device includes a sleeve that is radially movable inside the flue and an installation cylinder that is rotatably disposed inside the sleeve. A plurality of agitating plates are fixedly arranged around the inner wall of the installation cylinder. An installation frame is fixedly connected inside the sleeve, and a fan is installed on the installation frame. When the fan rotates, it blows air towards the agitating plates.

[0005] The device provided in this solution is installed into the flue through a perforated door. During operation, the sleeve moves radially within the flue, scooping up the accumulated ash. Simultaneously, the installation cylinder rotates within the sleeve, causing the agitator plate to disperse the scooped-up ash. The fan operates synchronously to blow away the dispersed ash, allowing it to be smoothly drawn away by the induced draft fan installed at the downstream purification equipment, thus achieving the purpose of ash removal. This method eliminates the need for excessive manual intervention and reduces the time required, solving the problems of long ash removal time, low efficiency, and safety hazards in existing flue ash removal technologies.

[0006] Furthermore, it also includes a pulling motor installed outside the flue, the pulling motor being connected to a cable, and a pulley installed inside the flue, with the other end of the cable passing through the flue and fixed to the sleeve via the pulley.

[0007] Furthermore, the motor, pulley, and cable are arranged in two sets.

[0008] Furthermore, two sets of pulleys are symmetrically arranged inside the flue.

[0009] Furthermore, a rotating motor is fixedly installed on the sleeve, the rotating motor is connected to a drive gear, and an annular toothed belt that meshes with the drive gear is fixedly connected to the inner wall of the mounting cylinder.

[0010] Furthermore, a retaining ring is fixedly connected inside the mounting cylinder between all the agitating plates and the annular toothed belt.

[0011] Furthermore, a sliding ring is protruding from the inner wall of the sleeve, and a sliding groove is recessed on the outer wall of the mounting cylinder for the sliding ring to slide into.

[0012] Furthermore, the flue is equipped with perforations for the cable to pass through.

[0013] Furthermore, the mounting sleeve is located in the middle of the sleeve, the mounting bracket is located at one end of the sleeve, and the wall thickness of the other end of the sleeve away from the mounting bracket gradually decreases from the inside to the outside.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By using a sleeve and an installation cylinder, the accumulated ash is shoveled up and broken up. Then, with the help of a fan, the broken ash is blown away, allowing it to be smoothly drawn away by the induced draft fan installed at the rear purification equipment, thus achieving the purpose of ash removal. This method can achieve ash removal without much manual intervention, and the time required is correspondingly shorter. It solves the problems of long time consumption, low efficiency, and safety hazards in existing flue ash removal technologies. At the same time, no one needs to enter the flue during use, thus avoiding unnecessary safety hazards. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] In an exemplary implementation, such as Figure 1As shown, this embodiment provides a flue cleaning device, which includes a sleeve 1 radially movable within a flue 16 and an mounting cylinder 2 rotatably disposed within the sleeve 1. Multiple agitator plates 3 are fixedly arranged around the inner wall of the mounting cylinder 2. A mounting frame 4 is fixedly connected inside the sleeve 1, and a fan 5 is mounted on the mounting frame 4. When the fan 5 rotates, it blows air towards the agitator plates 3. More specifically, a rotary motor 6 for driving the mounting cylinder 2 is fixedly installed inside the sleeve 1, and a motor 6 for driving the mounting cylinder 2 is also installed outside the flue 16. A pull motor 7 moves the sleeve 1 radially along the flue 16. The pull motor 7 is connected to a winch 8, on which a cable 9 is wound. The flue 16 also has a through hole 10 for the cable 9 to pass through. A pulley 11 is installed inside the flue 16. The cable 9 enters the flue 16 through the through hole 10, then passes through the pulley 11 and is fixed to the sleeve 1. Thus, the pull motor 7 drives the winch to wind and unwind the cable 9, thereby raising or lowering the sleeve 1 inside the flue 16. (In the prior art, the initial section of the flue 16 is generally vertical, similar to...) Dust accumulation typically occurs primarily at the lower end of the initial section. Initially, the sleeve 1, mounting cylinder 2, and other structures are installed through the perforated gate. The cable 9 enters the flue 16 through the perforation 10 and is then fixed to the sleeve 1. This fixing can be detachable, facilitating disassembly when cleaning is not required later. Furthermore, the pulling motor 7, cable 9, and pulleys 11 can be in two sets, with the pulleys 11 being symmetrical. This allows for smoother pulling of the sleeve 1 from both sides. During the pulling process, the sleeve 1 moves radially upward, which can scoop up the accumulated ash. At the same time, the mounting cylinder 2 rotates inside the sleeve 1, which drives the stirring plate 3 to disperse the scooped-up ash. The fan 5 runs synchronously to blow the dispersed ash, so that the ash can be smoothly drawn away by the induced draft fan set at the purification equipment behind, thus achieving the purpose of ash removal. In this way, ash removal can be achieved without too much manual intervention, and the time consumption is correspondingly shorter. This solves the problems of long time consumption, low efficiency and safety hazards in the existing technology of flue 16 ash removal.

[0024] like Figure 1 As shown, in a further embodiment, the mounting cylinder 2 is located in the middle of the sleeve 1, the mounting bracket 4 is located at one end of the sleeve 1, and the wall thickness of the other end of the sleeve 1 away from the mounting bracket 4 gradually decreases from the inside to the outside. The upper end of the sleeve 1 has a structure that is thinner at the top and thicker at the bottom, which can better remove the accumulated dust.

[0025] like Figure 1 , 2As shown in the more detailed scheme, the rotating motor 6 is connected to the drive gear 12, and the inner wall of the mounting cylinder 2 is also fixedly connected to the annular toothed belt 13 that meshes with the drive gear 12. When the rotating motor 6 runs, it can drive the drive gear 12 to drive the annular toothed belt 13 to rotate, thus driving the mounting cylinder 2 to rotate inside the sleeve 1. In order to prevent the scattered dust from falling onto the annular toothed belt 13 and the drive gear 12 and causing adverse effects, a retaining ring 14 located between all the stirring plates 3 and the annular toothed belt 13 is also fixedly connected inside the mounting cylinder 2. Of course, the retaining ring 14 can also be omitted. When the fan 5 is running, the dust is blown upwards, and with the help of the induced draft fan set at the rear purification equipment, the dust can be smoothly drawn away and will not fall downwards in large quantities.

[0026] like Figure 1 , 3 As shown, in a more detailed embodiment, in order to ensure that the mounting cylinder 2 rotates smoothly inside the sleeve 1, a sliding ring 15 is protruding on the inner wall of the sleeve 1, and a sliding groove is recessed on the outer wall of the mounting cylinder 2 for the sliding ring 15 to slide into. This means that the mounting cylinder 2 only rotates relative to the sleeve 1 under the cooperation of the sliding ring 15 and the sliding groove, thus improving stability.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
