Abstract

The invention discloses a process for reproducing paperboard from recovered wastepaper. The process comprises the following steps of: 1, mixing waste paper products in a beating tank until the paper products are changed to be pulp; 2, conveying the pulpous mixture in the beating tank into a paperboard machine for processing and filtering, and producing semi-finished paper products containing water by using the paperboard machine; 3, collecting filtered water and water splashed on the paperboard machine, and conveying the water into a storage tank; 4, conveying the water in the storage tank into the beating tank again for recycling; and 5, baking the semi-finished paper products containing the water in a heating furnace to obtain finished paper products, and conveying recovered steam into the beating tank, wherein a steam recovering device is arranged at the top end of the heating furnace. The process has the beneficial effects that: waste sheets are recovered for recycling, and sewage is recycled instead of being discharged, so that energy is saved, and the environment is protected.

Description

Waste paper reclaiming cardboard technology
Technical field
The present invention relates to a kind of waste paper reclaiming technology.
Background technology
Waste and old paper product often much all abandons arbitrarily, contaminated environment so not only, and waste a lot of resources, cut down a lot of trees.For waste paper does not abandon arbitrarily, the enterprise of recycling is also arranged, waste paper is changed into paper pulp regeneration produce cardboard or other paper product.Reached the certain social benefit though these reclaim enterprise's heat, minimizing is polluted and is economized on resources.But they have a common shortcoming to be exactly, and waste paper is changed in the process of pulp, need to absorb water, and the water that will use is then discharged, and causes second environmental pollution like this, more or less has the water of pollution to enter sewer.
Summary of the invention
To the deficiency of prior art, the present invention provides a kind of waste paper reclaiming cardboard technology that does not need sewage effluent.
To achieve these goals, the technical scheme that the present invention taked is:
Waste paper reclaiming cardboard technology, its processing step is following:
The first step stirs waste and old paper product in troughing, change into pulpous state up to paper product;
Second goes on foot, and the paste mixture in the troughing is input to processes filtration on the board machine, and board machine processes the cardboard semi-finished product that contain moisture;
In the 3rd step, after collecting, the water that spills on back and the board machine is input in the storage pool having filtered;
The 4th goes on foot, and the water in the storage pool is input in the troughing again reuse;
The 5th goes on foot, and the cardboard semi-finished product of being with moisture is placed in the heating furnace toasts, and just becomes the cardboard finished product after the oven dry, and there is the steam retracting device on the heating furnace top, and the water vapour of recovery is input in the troughing.
From troughing, paste mixture is extracted into board machine through water pump; Filtered and board machine on the water that spills collect the back and be input in the storage pool through water pump; Water in the storage pool is input in the troughing through water pump.
Beneficial effect of the present invention: waste and old paper recycling, energy-conserving and environment-protective do not have sewage discharge, all are cycling and reutilizations.An amount of water of regular replenishment gets into troughing, mainly is to think in process of manufacture, has water partly to enter in the atmosphere through the form of steam, in the process of oven dry, also is through with Steam Recovery, really realizes the zero-emission of sewage.
Description of drawings
Fig. 1, workflow sketch map of the present invention;
The specific embodiment
As shown in Figure 1, waste paper reclaiming cardboard technology, its processing step is following:
The first step stirs waste and old paper product in troughing 1, have motor-operated stirring arm in the troughing 1, is stirred to up to the waste paper article and changes into pulpous state;
Second goes on foot, and the paste mixture in the troughing 1 is input on the board machine 3 through water pump processes filtration, and board machine 3 processes the cardboard semi-finished product that contain moisture;
In the 3rd step, be input in the storage pool 2 after the water that spills on water after the filtration after having filtered and the board machine being collected (the board machine upper and lower side has individual gathering-device 4, collects the water that spills on the machine specially);
The 4th step was input to recycling in the troughing 1 again with the water in the storage pool 2, and the arrow among the figure is represented the direction of current.Circulation so successively.
The 5th goes on foot, and the cardboard semi-finished product of being with moisture is placed in the heating furnace toasts, and just becomes the cardboard finished product after the oven dry, and there is the steam retracting device on the heating furnace top, collects owing to heat the steam that is produced, and steam is recovered in the beater tub again.Discharge of pipes can be directly passed through in some place of this patent, if can not directly discharge, just through the water pump draining.
From troughing, paste mixture is extracted into board machine through water pump; The water that spills on water after having filtered and the board machine is collected the back and is input in the storage pool through water pump; Water in the storage pool is input in the troughing through water pump.
Beneficial effect of the present invention: waste and old paper recycling, energy-conserving and environment-protective do not have sewage discharge, all are cycling and reutilizations.An amount of water of regular replenishment gets into troughing, mainly is to think in process of manufacture, has water partly to enter in the atmosphere through the form of steam, in the process of oven dry, also is through with Steam Recovery, really realizes the zero-emission of sewage.
