Description

Technical Field

[0001] The utility model relates to the technical field of dust collector air ducts, in particular to a cleaning device for dust collector air ducts. Background Art

[0002] When the bag dust collector draws dust-laden gas from the lower air inlet duct of the dust collector through the guide plate into the ash hopper, coarse dust will fall into the ash hopper due to the collision of the guide plate and the reduction of gas velocity, and the remaining fine dust particles enter the filter bag chamber with the gas. Due to the inertia, diffusion, barrier, hooking, static electricity and other effects of the filter material fibers and fabrics, the dust is retained in the filter bag. The purified gas escapes from the bag and is discharged through the exhaust pipe.

[0003] In the use of the traditional bag dust collector inlet pipe, since the bag dust collector discharges the exhaust gas into the dust collector through the air inlet pipe for dust removal, the exhaust gas entering through the air inlet pipe contains a large amount of dust and impurities, and some dust and impurities will adhere to the inner wall of the air inlet pipe. The traditional air inlet pipe is unable to clean its own inner wall, which in turn reduces the use effect of the air inlet pipe.

[0004] A bag dust collector air inlet duct structure with publication number CN218794573U includes a ventilation duct, inside which a cleaning mechanism and a wind shield mechanism are fixedly installed respectively; the cleaning mechanism includes a first fixed rod fixedly installed inside the ventilation duct, an internal opening of the first fixed rod is rotatably connected to a cleaning rotating rod, the outer side of the cleaning rotating rod is rotatably connected to a cleaning ring, and the outer side of the cleaning ring is rotatably connected to the inner wall of the ventilation duct.

[0005] The device scrapes and cleans the inner wall of the air duct through a spiral cleaning ring, which causes damage to the inner wall of the air duct and the cleaning effect is not ideal. At the same time, the device drives the cleaning mechanism to clean through wind force, and the cleaning efficiency is low. Therefore, it is necessary to design a dust collector air duct cleaning device that improves the cleaning efficiency and effect of the ventilation duct. Utility Model Content

[0022] The following is a non-limiting detailed description of the technical solution of the present invention in conjunction with preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0023] See also Figure 1-3 The utility model provides a technical solution: a cleaning device for a dust collector air duct, comprising a ventilation duct 1, the output end of the ventilation duct 1 is connected to the inner cavity of the dust collector.

[0024] The ventilation duct 1 is provided with a cavity 2, which is opened at both ends. Strong wind components 3 are provided at both ends of the cavity 2, and a cleaning component 4 is provided between the two groups of strong wind components 3.

[0025] The strong wind component 3 includes a fixing frame 5 adapted to the inner wall of the cavity 2. Specifically, the fixing frame 5 is a rectangular frame. The four corners of the inner frame of the fixing frame 5 are fixedly connected to a connecting rod 6. The other end of the connecting rod 6 points to the center of the fixing frame 5 and is fixedly connected to a motor housing 7. A drive motor 8 is installed in the motor housing 7. A fan 9 is fixedly connected to the output shaft of the drive motor 8. The fan 9 is driven by the drive motor 8 to generate an airflow flowing toward the dust collector, thereby enhancing the efficiency of conveying the flue gas in the ventilation duct 1.

[0026] The output shafts of the drive motors 8 on the two groups of strong wind components 3 are arranged relative to each other, and the output shafts of the two groups of drive motors 8 are fixedly connected with a reciprocating screw 10. The reciprocating screw 10 is coaxially arranged with the output shaft. The reciprocating screw 10 is provided with two thread grooves with the same pitch and opposite rotation direction. The two ends of the thread groove are transitionally connected. The reciprocating screw 10 is an existing conventional technology.

[0027] The screw nut on the reciprocating screw 10 is connected to a cleaning assembly 4, and the cleaning assembly 4 includes a movable frame 11 adapted to the inner wall of the cavity 2. Specifically, the movable frame 11 is a rectangular frame, and the four corners of the inner frame of the movable frame 11 are connected to a connecting rod 2 12. The other end of the connecting rod 2 12 points to the center of the movable frame 11 and is fixedly connected to a fixed block 13. A threaded hole 14 is provided at the center of the fixed block 13, and the threaded hole 14 is screwed to the reciprocating screw 10. The fixed block 13 moves in a thread groove on the reciprocating screw 10 to one end of the thread groove and then moves into the other thread groove and continues to move in the opposite direction, so that the fixed block 13 moves to one end on the reciprocating screw 10 and continues to move in the opposite direction while the rotation direction of the reciprocating screw 10 remains unchanged.

[0028] The driving motors 8 on the two sets of strong wind components 3 drive the reciprocating screw 10 to rotate in the same direction, so that the movable frame 11 screwed to the reciprocating screw 10 moves to one end of the reciprocating screw 10 and then continues to move in the opposite direction to the other end, thereby realizing the reciprocating movement of the movable frame 11 along the axial direction of the reciprocating screw 10 under the drive of the driving motor 8.

[0029] Two sets of rotatable rollers 15 are provided on the four sides of the mobile frame 11 close to the inner wall of the cavity 2. The rollers 15 are in direct contact with the inner wall of the cavity 2. The rollers 15 roll along the axial direction of the reciprocating screw 10. During the movement of the mobile frame 11, the rollers 15 rotate to reduce the resistance of the mobile frame 11 during movement.

[0030] Several groups of brushes 16 are connected to the positions of the rollers 15 on the four outer walls of the moving frame 11 close to the inner wall of the cavity 2. During the movement of the moving frame 11, the dust attached to the inner wall of the cavity 2 is brushed off by the brushes 16. At the same time, the airflow generated by the fan 9 carries the dust falling off the inner wall of the cavity 2 into the dust collector and falls into the ash hopper inside the dust collector.

[0031] In this embodiment, when the flue gas enters the dust collector through the ventilation duct 1, the strong wind component 3 is started, and the fan 9 on the strong wind component 3 rotates to generate an airflow blowing toward the dust collector, thereby improving the efficiency of flue gas transportation.

[0032] At the same time, the two sets of drive motors 8 drive the reciprocating screw 10 to rotate, and the reciprocating screw 10 drives the cleaning component 4 to move. When the cleaning component 4 moves to one end of the reciprocating screw 10, the reciprocating screw 10 acts on the cleaning component 4 to move in the opposite direction of the axis of the reciprocating screw 10. After the cleaning component 4 moves in the opposite direction to the other end of the reciprocating screw 10, it moves in the opposite direction of the axis of the reciprocating screw 10 again, so that the cleaning component 4 moves back and forth along the axis of the reciprocating component. At the same time, the brush 16 cleans the dust attached to the inner wall of the cavity 2. The cleaned dust follows the air flow generated by the fan 9 into the dust collector and falls into the ash hopper of the dust collector, thereby cleaning the inner wall of the ventilation duct 1 without damaging the inner wall of the ventilation duct 1.
