The utility model discloses can optimize the transport of tobacco powder stalk bamboo slips.
Description
Technical Field
The utility model relates to a material conveying device, especially the conveying device of tobacco powder stalk bamboo slips in the tobacco industry, this conveying device still can be used to the transport of dry powder or little granular material.
Background
In the cigarette production, the stalk sticks separated by the cigarette making machine group and tobacco powder and the like are collected in a centralized manner through stalk stick collecting and dedusting equipment, enter a discharge valve after being preliminarily separated through cyclone dedusting equipment, enter a feed hopper after the tobacco powder stalk sticks discharged from the discharge valve enter the feed hopper, and are conveyed to a stalk stick secondary separator through a section of vibration groove with the length of about 4m after being discharged from the feed hopper to be winnowed.
The groove conveyor shakes includes the motor, the belt, the eccentric wheel, the balancing piece, and a support, spare part such as cell body and rocking arm, adopt the motor to pass through belt drive, drive the eccentric wheel rotation on the balancing piece, the rethread rocking arm drives the groove vibration of shaking and carries the tobacco powder stalk, its structure is more complicated, the cost is higher, the price is about 3 ten thousand yuan, and owing to move under the vibration condition for a long time in the use, consequently the fault rate is high, use and maintenance cost are high (the power of motor is 5.5 KW), the groove of shaking in addition uses belt drive, its security is also relatively poor. When the tobacco powder stalk sticks are conveyed through the vibration groove, a discharge hole of the feed hopper is blocked frequently, so that the tobacco powder stalk sticks in the feed hopper cannot enter the vibration groove smoothly; when the tobacco powder stems fall from the discharge port of the feed hopper to the vibration groove, dust is generated due to certain fall, and the surrounding environment is polluted.
Disclosure of Invention
The utility model aims at providing a conveyor of offal stalk bamboo slips to optimize the transport of offal stalk bamboo slips.
The conveying device for the tobacco powder and the stem sticks comprises a conveying pipe and a feeding hopper, wherein a discharge port of the feeding hopper is connected and communicated with a feed end of the conveying pipe, a reducing pipe is arranged in the feed end of the conveying pipe, a large-diameter end of the reducing pipe is positioned at the outer end of the feed end of the conveying pipe, a small-diameter end of the reducing pipe is positioned at the inner end of the feed end of the conveying pipe, and the small-diameter end of the reducing pipe is positioned below the discharge port of the feeding hopper; the air outlet of the air blower is connected with the large-diameter end of the reducing pipe.
The reducing pipe is an eccentric reducing pipe, and the small-diameter end of the reducing pipe is far away from the discharge hole of the feed hopper.
The air outlet of the air blower is flexibly connected with the large-diameter end of the reducing pipe through a corrugated pipe.
When the tobacco powder separating machine works, tobacco powder stems enter the feed hopper, fall into the feed end of the feed conveying pipe from the discharge port of the feed hopper under the action of gravity and negative pressure, then obliquely ascend through the feed conveying pipe under the action of positive pressure wind power of the air blower, and finally flow out of the discharge end of the feed conveying pipe and enter the secondary separating machine.
The feed delivery pipe and the reducing pipe in the feed end thereof actually form a venturi tube, and negative pressure is generated around the small-diameter end of the reducing pipe according to the venturi principle during the operation of the air blower. Because the minor diameter end of the reducing pipe is positioned below the discharge port of the feed hopper, the discharge port of the feed hopper is positioned in a negative pressure area, so that not only can materials at the lower part of the feed hopper smoothly enter the feed conveying pipe under the action of suction force, and the blockage of the materials at the discharge port of the feed hopper is avoided. The utility model discloses spare part is few, simple structure, and is with low costs, need not maintain the maintenance basically, the power 3KW of the motor of air-blower can, the fault rate is extremely low.

FIG. 2 is a front view of a reducing tube.
Fig. 3 is a right side view of fig. 2.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in figure 1, this conveyor of tobacco powder stalk bamboo slips includes conveying pipeline 1, feeder hopper 2 and air-blower 3, the discharge gate of feeder hopper 2 links up the intercommunication with the feed end of conveying pipeline 1, be provided with a reducing pipe 5 in the feed end of conveying pipeline 1, as shown in figure 2 and figure 3, this reducing pipe 5 is eccentric reducing pipe, the major diameter end of reducing pipe 5 is located the outer end of conveying pipeline 1 feed end, the minor diameter end of reducing pipe 5 is located the inner of conveying pipeline 1 feed end, and the minor diameter end of reducing pipe 5 is located the discharge gate below of feeder hopper 2, keep away from the discharge gate of feeder hopper 2, can make great space have between the discharge gate of the small diameter end of reducing pipe 5 and feeder hopper 2 like this. The air outlet of the air blower 3 is flexibly connected with the large-diameter end of the reducing pipe 5 through the corrugated pipe 4, so that the vibration of the air blower 3 cannot be transmitted to the material conveying pipe 1.
During operation, tobacco powder stems enter the feed hopper 2 and then fall into the feed end of the feed delivery pipe 1 from the discharge port of the feed hopper 2 under the action of gravity and negative pressure, then obliquely move upwards through the feed delivery pipe 1 under the action of positive pressure wind power of the air blower 3, and finally flow out of the discharge end of the feed delivery pipe 1 and enter the secondary separator.
