Description

Carbon black packing unloader

Technical Field

The utility model relates to the field of blanking devices, in particular to a carbon black packaging blanking device.

Background

The materials are naturally stacked by gravity blanking, and after the materials are stacked to the angle, the materials are stacked upwards and continuously stacked, the materials naturally slide down, the angle is kept unchanged, only the height is increased, the bottom area is increased, carbon black is no exception, and the repose angle of the carbon black is about 50 degrees generally (see figure 1).

Due to the existence of the repose angle, the carbon black material in the packaging bag has the conditions of high material level in the center and low material level around the bag, the filling rate of the packaging bag only reaches 70-80%, the utilization rate of the packaging bag is reduced, and the packaging bag is wasted.

SUMMERY OF THE UTILITY MODEL

The utility model provides a carbon black packaging and blanking device for solving the problems in the prior art, which adopts high-speed rotating blades to enable carbon black entering the upper opening end of a packaging bag to generate centrifugal force to be thrown out to the periphery of the inner wall of the packaging bag and naturally fall down, so that the carbon black blanking direction is changed, the carbon black filling amount in the packaging bag is increased, and the purpose of saving the using amount of a carbon black packaging bag is achieved.

The carbon black packaging bag comprises a carbon black packaging bag with a discharging pipe at the top, wherein a stirring blade with a driving device is arranged at the bottom of the discharging pipe, a control valve is arranged at the top, carbon black enters the carbon black packaging bag through the discharging pipe, is thrown to the periphery of the inner side of the packaging bag through the stirring blade rotating at a high speed, then naturally falls down along the inner wall of the packaging bag by virtue of gravity to fill the packaging bag, and the material falling is influenced by centrifugal force, so that the discharging direction of the carbon black is changed, and the carbon black filling amount in the packaging bag is increased. The carbon black packaging bag at the side part of the blanking pipe is provided with a dust absorption pipe connected with dust absorption equipment, so that the packaging bag is ensured to be in a negative pressure state in the operation process, and the carbon black dust is prevented from escaping to pollute the environment.

The improved carbon black packaging bag is characterized in that a weighing sensor is arranged at the bottom of the carbon black packaging bag and is connected with a control valve through a control box. When the carbon black material in the packaging bag is filled to the set weight, the weighing sensor transmits a signal to the control box, the control box automatically outputs a signal to close the valve of the carbon black feeding pipe, and the packaging is completed.

In a further improvement, the stirring blade is coaxial with the carbon black packaging bag.

The utility model has the beneficial effects that: the high-speed rotating blades are adopted, so that carbon black entering the upper opening end of the packaging bag generates centrifugal force and is thrown to the periphery of the inner wall of the packaging bag to naturally fall down, the carbon black discharging direction is changed, the carbon black filling amount in the packaging bag is increased, and the purpose of saving the use amount of the carbon black packaging bag is achieved.

Detailed Description

The utility model will be further explained with reference to the drawings.

The structure of the utility model is shown in fig. 2, fig. 3 is a sectional view from a-a in fig. 2, and fig. 4 is a sectional view from B-B in fig. 2. The carbon black packaging bag comprises a carbon black packaging bag 4 with a discharging pipe 1 at the top, wherein a stirring blade 3 with a driving device 7 is arranged at the bottom of the discharging pipe 1, a control valve 2 is arranged at the top, carbon black 9 enters the carbon black packaging bag 4 through the discharging pipe 1 and then is thrown to the periphery of the inner side of the packaging bag through the stirring blade 3 rotating at a high speed, then naturally falls down along the inner wall of the packaging bag by means of gravity to fill the packaging bag, and the material falling is influenced by centrifugal force, so that the carbon black discharging direction is changed, and the carbon black filling amount in the packaging bag is increased. The carbon black packaging bag at the side part of the blanking pipe is provided with a dust absorption pipe 8 connected with dust absorption equipment, so that the packaging bag is ensured to be in a negative pressure state in the operation process, and the carbon black dust is prevented from escaping to pollute the environment.

Further improve, carbon black wrapping bag bottom be provided with weighing sensor 5, weighing sensor 5 passes through control box 6 and links to each other with control valve 2. When the carbon black material in the packaging bag is filled to the set weight, the weighing sensor transmits a signal to the control box, the control box automatically outputs a signal to close the valve of the carbon black feeding pipe, and the packaging is completed.

The complete use process of the utility model is as follows:

1. when entering the carbon black packaging operation, the control box controls the control valve 2 of the blanking pipe to open,

2. carbon black enters from the blanking pipe 1 by means of self gravity, passes through the control valve 2 and enters into the carbon black packaging bag 4.

3. A coaxial high-speed rotating stirring blade 3 is arranged at the upper end of a packaging bag 4, and the stirring blade 3 is rotated by a stirring prime mover 7. When carbon black got into wrapping bag 4, collided high-speed rotatory stirring vane 3, the carbon black material received centrifugal force and is got rid of around to the wrapping bag inboard, then relies on gravity to fall naturally along the wrapping bag inner wall and fills the wrapping bag, because the material whereabouts receives centrifugal force's influence to change carbon black unloading direction, increased the carbon black filling volume in the wrapping bag.

4. When the carbon black material is filled to the set weight in the packaging bag, the weighing sensor 5 transmits a signal to the control box 6, the control box 6 automatically outputs a signal to close the control valve 2 of the carbon black discharging pipe, and the packaging is completed.

5. The side of the blanking pipe is connected with a dust suction pipe 8, and the dust suction pipe 8 is communicated with related dust suction facilities, so that the packaging bag 4 is ensured to be in a negative pressure state in the operation process, and the carbon black dust is prevented from escaping to pollute the environment.

While the utility model has been described in terms of its preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model.
