Description

Pulping device

Technical Field

The utility model relates to a pulping device, it belongs to papermaking technical field.

Background

In the existing papermaking technology, raw materials are added into a pulper according to the process requirements and are discharged into a raw pulp tank through a sand setting disc, the raw pulp enters a sand remover through a pulp pump, and garbage and good pulp are screened out through a pressure screen and are respectively discharged into a garbage collection box and a circular screen; the screening process is complex in flow, high in power consumption, time-consuming and labor-consuming in operation and high in labor capacity, original fillers and fine fibers in raw materials are seriously lost, water consumption is increased, pressure is high for subsequent work, quality instability factors often appear, the flow is complex, the labor capacity of workers is high, and the cost is difficult to reduce.

SUMMERY OF THE UTILITY MODEL

The utility model provides a pulping device aiming at the defects existing in the prior art.

The utility model provides an above-mentioned technical problem's technical scheme as follows:

the utility model provides a pulping device, includes pulper, the steady case of liquid level, the sieve is jumped to the hole sieve, good thick liquid pond, pressurized screen that communicate in proper order and goes the mould, be equipped with stuff pump first between pulper and the steady case of liquid level, the pressurized screen is equipped with stuff pump second between the good thick liquid pond.

Further, the hole screen is a vibrating screen with the size of 0.2-0.25 mm.

Furthermore, a slotted screen jumping screen is arranged between the pressure screens and the rotary screen.

Further, the slot screen jumping screen is a 0.2mm slot screen.

Further, drain outlets are arranged on the liquid level pulp stabilizing box, the hole sieve and the pressure sieve, and a communicated garbage collecting box is arranged below the drain outlets.

Compared with the prior art, the beneficial effects of the utility model are that: the improved process flow is simple to operate, the original filler in the raw materials can be kept, the loss is reduced, the water consumption is reduced, the quality is stable, the power consumption is greatly reduced, the labor amount is also greatly reduced, the effects of energy conservation and consumption reduction are achieved, the quality of the product is ensured, and the production efficiency is improved.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

The utility model provides a pulping device, includes pulper 1, the steady case 3 of liquid level, the sieve jump of hole sieve 4, good thick liquid pond 5, pressurized screen 7 that communicate in proper order and goes mould 9, be equipped with stuff pump A2 between pulper 1 and the steady case 3 of liquid level, pressurized screen 7 is equipped with stuff pump second 6 between the good thick liquid pond 5.

The hole sieve 4 is a vibrating sieve with the diameter of 0.2-0.25 mm.

A slotted screen jumping sieve 8 is also arranged between the pressure sieves 7 and the rotary screen 9.

The slotted screen jumping screen 8 is a slotted screen of 0.2 mm.

And the liquid level slurry stabilizing box 3, the hole sieve jumping sieve 4 and the pressure sieve 7 are all provided with a sewage discharge outlet, and a communicated garbage collecting box 10 is arranged below the sewage discharge outlet.

When the device works, raw materials are put into a pulper 1, the raw materials are crushed and then are pumped into a liquid level stabilizing box 3 through a pulp pump A2, after the liquid level is stabilized, the raw materials are screened through a 0.25mm hole screen jumping screen 4, screened garbage is collected and discharged into a garbage collecting box 10 in a unified way, screened and filtered good pulp enters a good pulp pool 5 and then enters a pressure screen 7 through a pulp pump B6, secondary screening is carried out, bad pulp screened out in the pressure screen 7 is discharged into a 0.2mm seam screen jumping screen 8 for secondary screening, screened good pulp is discharged into a destroyer, all good pulp enters the next process, the screened garbage is discharged into the garbage collecting box 10 for reasonable utilization, the process flow is simple to operate after improvement, the original filler in the raw materials can be kept, the loss is reduced, the water consumption is reduced greatly, the quality is stable, the power consumption is reduced greatly, the labor amount is reduced greatly, the effects of energy conservation and consumption reduction are achieved, the production efficiency is improved while the quality of the product is ensured.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
