Description

Pulper

Technical Field

The utility model relates to a pulper, in particular to a pulper.

Background

The waste paper pulper has the main functions that waste paper and water are mixed in the tank body at a certain concentration, the rotor rotating at a high speed enables mixed slurry to move downwards in the center of the tank body along the axis direction of the rotor and upwards move along the wall of the tank body at the periphery of the tank body, so that internal circulation is formed in the tank body, the rotor rotating at a high speed cuts and kneads the contacted waste paper, the vortex generated by rotation of the rotor enables waste paper pieces to move at a different speed, and the fibers can rub with each other, so that the waste paper is accelerated to absorb water and swell, and finally the waste paper is defibered into qualified fibers. The rotor and the trough body are used as key components of the pulper, whether the structural design is reasonable or not and whether the rotor and the trough body are perfectly fit or not are crucial to improving pulping efficiency of a pulping system and reducing operation energy consumption. The current pulper has unreasonable structure and can not fully dredge paper pulp circularly.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, it is an object of the present invention to provide a pulper

In order to realize the purpose, the technical scheme of the utility model is as follows: the utility model provides a pulper, includes barrel and the interior rotor pivoted main motor of drive barrel, and the barrel, the vertical setting of rotor, and the rotor lies in the first half of barrel and is provided with helical blade, and the rotor of barrel bottom is provided with the S type and turns over the thick liquid leaf, and the S type is turned over thick liquid leaf below and is set up the thick liquid room of sieve for the top, and thick liquid room lower extreme is provided with the play thick liquid mouth with external intercommunication, and one side is provided with the vertical guide plate that separates the barrel inner wall in the barrel, and barrel top one side is provided with the filler.

Further, a driving belt wheel of the main motor is in transmission connection with a driven belt wheel at the lower end of the rotor through a belt.

Further, in order to facilitate blanking, the bottom of the cylinder is conical.

Furthermore, in order to facilitate the water adding dilution, a dilution water pipe for adding water is arranged on one side of the bottom of the cylinder body.

Further, the bottom of the cylinder is supported on the ground or a base by legs.

Further, the pulp chamber is cylindrical and has a bottom with a slope so that the pulp outlet is at the lowest point.

The optimized structure of the cylinder and the guide plate can fully mix the slurry, and can generate strong vortex with lower input power, so that strong friction (non-mechanical acting force) is generated between fibers, thereby ensuring constant defibering efficiency. Therefore, the utility model has the advantages of novel and reasonable structural design, high pulping concentration, water saving, energy saving and small occupied area.

Drawings

The present invention will now be further described with reference to the accompanying drawings.

FIG. 1 is a schematic structural diagram of the present invention.

Detailed Description

As shown in figure 1, a pulper comprises a cylinder 1 and a main motor 3 for driving a rotor 2 in the cylinder 1 to rotate, a driving belt wheel of the main motor 3 is in transmission connection with a driven belt wheel at the lower end of the rotor 2 through a belt 9, the bottom of the cylinder 1 is conical, the cylinder 1 and the rotor 2 are vertically arranged, the upper half part of the rotor 2 positioned on the cylinder 1 is provided with a helical blade, the rotor 2 at the bottom of the cylinder 1 is provided with an S-shaped paddle turning blade 4, a pulp chamber 6 with a sieve plate 5 arranged at the top is arranged below the S-shaped paddle turning blade 4, the lower end of the pulp chamber 6 is provided with a pulp outlet 7 communicated with the outside, the pulp chamber 6 is cylindrical, the bottom of the pulp chamber has a slope, the pulp outlet 7 is arranged at the lowest point, one side in the cylinder 1 is provided with a guide plate 8 vertically separating the inner wall of the cylinder 1, one side at the top of the cylinder 1 is provided with a water filling port, one side at the bottom of the cylinder 1 is provided with a dilution water pipe 10 for adding water, the bottom of the bowl 1 is supported on the ground or base by legs 11.

The working principle of the utility model is as follows: firstly, opening a valve of a water filling port at the top end of the pulper, adding certain water into a cylinder body of the pulper through the water filling port, and adding chemicals according to process requirements.

And starting the main motor, uniformly feeding a certain amount of waste paper into the cylinder by using conveying equipment or manpower, and continuously supplementing water until the operation conditions of the equipment are met.

The main motor drives the rotor to rotate at a high speed through the belt, the helical blade on the upper portion of the rotor conveys pulp to the bottom of the equipment, the pulp moves around the groove body along the centrifugal force generated by rotation of the S-shaped pulp turning blade (and a blade commonly used at present and similar to a turbine structure) on the bottom of the rotor, and moves upwards to the upper portion of the equipment along the flow deflector at the bottom of the conical groove body, and then moves towards the center of the barrel body under the pushing of the pulp moving at the bottom, finally, a vortex internal circulation is formed in the barrel body, and the waste paper is defibered into qualified pulp after being continuously operated for a period of time.

Continuously operating the equipment for a period of time, extracting the slurry, and preparing for discharging after the slurry is qualified through inspection.

And opening a valve of a bottom dilution water pipe, wherein dilution water enters the barrel through a water filling port to be mixed with the slurry, diluting the slurry to the working concentration of an unloading pump, enabling the slurry to enter the slurry chamber through a sieve plate positioned at the top of the slurry chamber, then opening an unloading valve arranged on a slurry outlet at the bottom of the slurry chamber, and discharging the slurry through an unloading pump.

After the blowing is finished, close unloading pump, dilution water valve, discharge valve, the while clean up equipment bottom impurity gets into next duty cycle afterwards.

The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes and modifications that can be made by one skilled in the art without departing from the spirit and principles of the utility model should fall within the protection scope of the utility model.
