Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a fly ash quantitative feeding device. Background Art

[0002] Fly ash can be used as an important raw material for cement production. It can be processed into various types of cement: P, Pozz, PC, Slag, etc. Among these cements, Pozz cement is the most commonly used. It can not only reduce production costs, but also improve the comprehensive properties of hardened cement such as strength and impermeability.

[0003] When cement is produced, fly ash materials need to be discharged from the inside of the silo through a feeding device for quantitative feeding. In the prior art, most quantitative feeding devices can only transport materials. When the fly ash is piled up, it is easy to cause blockage in the material discharge channel. Since the feeding device cannot break up the accumulated fly ash, the fly ash cannot be quantitatively fed, which affects the cement production and is not practical. Therefore, it is necessary to redesign a fly ash quantitative feeding device to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-7 A fly ash quantitative feeding device comprises a silo 1, two stirring shafts 2 are rotatably installed inside the silo 1, first gears 3 are fixedly installed on the outer walls of the two stirring shafts 2, the two first gears 3 are meshed with each other, a first motor 5 connected to one of the stirring shafts 2 is fixedly installed on the outer wall of the silo 1 through a supporting mechanism, the supporting mechanism comprises a supporting plate 4 fixedly installed on the outer wall of the silo 1, the first motor 5 is fixedly installed on the outer wall of the supporting plate 4, a plurality of stirring rods 7 are fixedly installed on the outer walls of the two stirring shafts 2 through a connecting mechanism, the connecting mechanism comprises a connecting sleeve 6 fixedly installed on the outer wall of the stirring shaft 2, and each stirring rod 7 is fixedly installed on the outer wall of the connecting sleeve 6.

[0025] The bottom wall of the silo 1 is fixedly connected to a discharge pipe 9 through a discharge pipe 8, an auger blade 10 is rotatably installed inside the discharge pipe 9, and the outer wall of the rotating shaft of the auger blade 10 is connected to one of the stirring shafts 2 through a transmission mechanism. The transmission mechanism includes a pulley 11 fixedly installed on the outer wall of the rotating shaft of the stirring shaft 2 and the auger blade 10, and the two pulleys 11 are connected for transmission through belts. A radar level meter 12 is fixedly installed on the upper end surface of the silo 1, a toothed plate 13 is fixedly installed on the inner wall of the silo 1, a reciprocating screw 14 is rotatably installed inside the silo 1, and a second motor 15 connected to the reciprocating screw 14 is fixedly installed on the outer wall of the silo 1.

[0026] A screw sleeve 17 is threadedly installed on the outer wall of the reciprocating screw 14 through a limiting mechanism. The limiting mechanism includes a limiting rod 16 fixedly installed inside the silo 1. The limiting rod 16 slides through the screw sleeve 17. The limiting rod 16 can limit the screw sleeve 17 so that the screw sleeve 17 can only move axially along the outer wall of the reciprocating screw 14. A cleaning roller 18 is rotatably installed on the outer wall of the screw sleeve 17. The outer wall of the rotating shaft of the cleaning roller 18 is connected to the tooth plate 13 through a rotating mechanism. The rotating mechanism includes a second gear 19 fixedly installed on the outer wall of the rotating shaft of the cleaning roller 18, and the second gear 19 is engaged with the tooth plate 13.

[0027] When the utility model is used, the radar level meter 12 can detect the stacking height of the fly ash inside the silo 1. When the stacking height drops, the discharge amount can be monitored by the radar level meter 12, thereby realizing the function of quantitative feeding. When feeding the fly ash, the first motor 5 drives one of the stirring shafts 2 to rotate, and one of the stirring shafts 2 can drive the other stirring shaft 2 to rotate through two first gears 3 that are engaged with each other. At this time, the two stirring shafts 2 rotate in opposite directions under the engagement of the two first gears 3. The two stirring shafts 2 then drive the multiple stirring rods 7 to rotate respectively through the cooperation of the connecting sleeve 6. With the cooperation of the multiple stirring rods 7, the fly ash inside the silo 1 can be stirred and dispersed, thereby preventing the fly ash from accumulating and agglomerating inside the silo 1 and affecting the feeding.

[0028] At the same time, one of the stirring shafts 2 drives the auger blades 10 to rotate through two pulleys 11 connected by belts. When fly ash falls into the discharge pipe 9 through the discharge pipe 8, the rotating auger blades 10 increase the discharge efficiency of the fly ash. When the fly ash adheres to the bottom wall of the probe of the radar level meter 12 and blocks it, the second motor 15 drives the reciprocating screw 14 to rotate. The reciprocating screw 14 drives the screw sleeve 17 to move through the cooperation with the limit rod 16, and the screw sleeve 17 drives the cleaning roller 18 to move. While moving, the cleaning roller 18 can drive the second gear 19 to move and engage with the tooth plate 13. Through the engagement of the second gear 19 with the tooth plate 13, the cleaning roller 18 can rotate on the outer wall of the screw sleeve 17, thereby enabling the cleaning roller 18 to rotate while moving, thereby cleaning the bottom wall of the probe of the radar level meter 12, thereby preventing the fly ash from affecting the radar level meter 12 from monitoring the internal material level of the silo 1.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
