The embodiments of the present invention will be described in detail below, and the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
Referring to fig. 1 to 3, the embodiment discloses a tobacco dust removal and blockage prevention system, which comprises a dust remover 1, a conveyor 6, a loosening device 4, an alarm 9 and a controller 10, wherein the conveyor 6 is a screw conveyor, the loosening device 4 is connected between the dust remover 1 and the conveyor 6, and an ash discharge valve 3 is arranged at the bottom of an ash hopper 2 of the dust remover 1.
The loosening device 4 comprises a main box body 4a, a feeding barrel 4b arranged at the top of the main box body 4a, a discharging barrel 4c arranged at the bottom of the main box body 4a, and a loosening mechanism arranged in a cavity inside the main box body 4 a. The main box body 4a is a hollow disc-shaped box body, the outer diameter of the feeding cylinder 4b is smaller than that of the discharging cylinder 4c, the outer diameter of the discharging cylinder 4c is equal to the width of the main box body 4a, and the wall thicknesses of the main box body 4a, the feeding cylinder 4b and the discharging cylinder 4c are equal. The loosening mechanism is an impeller 4d, the impeller 4d comprises a wheel disc and a plurality of blades 4g arranged in the circumferential direction of the wheel disc, the wheel disc is fixed on a rotating shaft 4e, the rotating shaft 4e is connected with an output shaft of a second motor 4f, the blades 4g are arc-shaped, and the thickness of the blades 4g is gradually reduced from inside to outside. The impeller 4d may be made of plastic.
The feeding barrel 4b at the top of the loosening device 4 is connected with the outlet end of the ash discharging valve 3, the discharging barrel 4c at the bottom of the loosening device 4 is connected with the feeding hole of the conveyor 6 through a connecting pipe 5, the connecting pipe 5 can adopt hoses such as corrugated pipes, the two ends of the connecting pipe 5 are detachably connected with the feeding holes of the discharging barrel 4c and the conveyor 6 respectively, and during specific connection, the two ends of the connecting pipe 5 can be sleeved outside the feeding holes of the discharging barrel 4c and the conveyor 6 respectively and are tightly sleeved through an annular hoop.
The top of the conveyor 6 is provided with a transparent observation window 7, and the observation window 7 can be made of glass plates. And a rotating speed sensor 8 for detecting the rotating speed of a transmission shaft in the conveyor 6 is arranged on the observation window 7.
The ash discharging valve 3 is driven to be opened or closed by a first motor 11, the impeller 4d is driven to operate by a second motor 4f, the conveyor 6 drives the internal transmission shaft to rotate by a third motor 12, the first motor 11, the second motor 4f, the third motor 12, the rotating speed sensor 8 and the alarm 9 are respectively electrically connected with a controller 10, and the controller 10 controls the first motor 11, the second motor 4f, the third motor 12 and the alarm 9 by rotating speed information transmitted by the rotating speed sensor 8. Wherein, the alarm 9 can adopt an explosion-proof acousto-optic alarm of a red, yellow and green LED.
Under the normal working state, the rotating speed of the auger of the conveyor 6 is 50 +/-3 r/min, the first motor 11 of the ash discharge valve 3 and the third motor 12 of the conveyor 6 are in an open state, the second motor 4f of the loosening device 4 is in a closed state, and the alarm 9 displays a green light to indicate the normal state.
If the ash bucket 2 contains agglomerated tobacco powder, the conveying resistance of the conveyor 6 is increased, and the rotating speed of the auger of the conveyor 6 is reduced. When the rotating speed sensor 8 monitors that the rotating speed of the auger of the conveyor 6 is lower than 35r/min, the alarm 9 displays a yellow light, enters an early warning state, and gives out discontinuous early warning sound to remind a worker to pay attention to the problem of the tobacco powder incoming material and observe and feed back in time; meanwhile, the controller 10 controls the second motor 4f of the loosening device 4 to be turned on, and the rotating shaft 4e drives the impeller 4d to rotate at a speed of 500 r/min. The impeller 4d with high rotation can not only loosen and smash the caking tobacco powder, but also form a certain negative pressure in the cavity, thereby being beneficial to the tobacco dust and the caking tobacco powder in the ash bucket 2 to be sucked out in time. The agglomerated tobacco powder is loosened and broken into fine-particle tobacco powder, the auger conveying resistance of the conveyor 6 is reduced, when the rotating speed of the auger is recovered to 50 +/-3 r/min, the controller 10 automatically turns off the second motor 4f of the loosening device 4, the impeller 4d stops rotating, and the alarm 9 displays a green light at the moment and recovers to a normal state.
If the caking tobacco powder in the ash bucket 2 is very hard and solid, the supplied materials are very much, or foreign matters are mixed in, or other extreme special conditions, the rotating speed of the auger of the conveyor 6 is easy to continuously reduce, and the auger is finally blocked, namely when the rotating speed of the auger of the conveyor 6 is monitored by the rotating speed sensor 8 to be 0r/min, the controller 10 automatically closes the third motor 12 of the conveyor 6, the first motor 11 of the ash discharge valve 3 and the second motor 4f of the loosening device 4, thereby effectively preventing the motors from being burnt out or the auger from being damaged due to blockage; meanwhile, the alarm 9 displays a red light, enters an alarm state, sends out a long-sounding alarm sound and reminds workers of timely maintenance and cleaning. For not influencing the continuity and the stability of production, the staff can unpack the connecting pipe 5 of conveyer 6 feed inlet department apart to manually open the first motor 11 of unloading valve 3, change to temporarily and connect the workbin to collect tobacco powder, treat the jam tobacco powder in the conveyer 6 and by the clearance after finishing, resume original operating condition again. In addition, the conveyer 6 is provided with an observation window 7 so that workers can easily observe the operation state of the packing auger and the conveying condition of tobacco powder when inspecting at a site inspection tour.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
