Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a deinking and cellulose separator,

The present invention relates to a deinking and cellulose separation apparatus, and more particularly, to a waste paper deinking and cellulose separation apparatus capable of effectively separating ink, gutto and cellulose from waste paper pulverized by mixing with chemicals and water.

Recently, we are concentrating on developing eco-friendly processes at national and enterprise levels in accordance with the conventions and policies for environmental protection. Especially, in order to solve the problems of depletion of forest resources, revival and recycling researches of abolition are being actively carried out.

A representative process during the recycling of waste paper is deinking process for removing ink from the waste paper. It is pointed out that one of the difficulties in recycling waste paper is the operation of removing ink from the paper due to a combination of various kinds of polymer components.

In this deinking process, the float floating method is a method of separating ink particles having relatively hydrophobic properties by attaching them to air bubbles by floating them, as compared with pulp fibers. The hydrodynamic behavior of the material and the surface physicochemical properties The efficiency depends on the characteristics.

 That is, as the ink particles are completely separated from the regenerated fiber, the separated ink particles are agitated so as to sufficiently collide with the bubbles, and finally the deinking treatment can be smoothly performed when the ink particles are physically adsorbed on the bubbles.

However, in the actual process, pulp fibers and inorganic fillers other than ink float together with the ink, so that the floating float rejection is discharged more than the weight of the printed ink, and the recycling efficiency is very low.

These problems not only lead to waste of waste to be recycled but also waste water and power for disposal of the waste paper, and the lost waste floating rejection eventually becomes polluted due to landfill or incineration treatment As a result.

In order to save environmentally friendly recycling of resources and to save foreign currency, abolition deodorization and deodorization process have been demanded to improve the yield and to reduce waste and to separate high quality cellulose.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, with reference to the accompanying drawings, a description will be given of the structure of a de-wastage de-pulping and cellulose separator of the present invention.

FIG. 1 is a cross-sectional view showing the structure of a body according to a preferred embodiment of the present invention, showing an optimal tank structure according to the present invention for deinking and separating cellulose from waste paper. In the present invention, the tank is divided into a lower first body 110 and an upper second body 120. In this case, the first body 110 and the second body 120 are coupled to each other, The tank in which the process takes place is composed.

First, the first body 110 is formed in a tubular shape with its upper side opened. On the other hand, a supply part 111 for supplying a raw material including pulverized waste paper by mixing water is connected to the first body 110, . At this time, the raw material to be supplied is a waste paper of liquid phase mixed with water and medicine, and therefore, a pump capable of supplying it is provided.

In addition, since the upper portion of the first body 110 is opened, the fence portion 112 having a predetermined pattern of concavo-convex structure along the upper edge is provided. In other words, the overflow of the ink floated in the first body is made through the concave groove and the concave and the groove are formed continuously and alternately, and the outflow of the waste paper component excluding the ink component is minimized do.

A first discharge portion 114 having a first valve 113 is provided on the other side of the first body 110 so that the raw material supplied through the supply portion 111 can be deinked and discharged therefrom. And a second discharge portion 116 having a second valve 115 is formed at a lower side of the first body 110 to discharge the precipitated paper filler. At this time, the second body 120 has a shape to be narrowed downward, and the second discharge portion 116 is formed at the lower end to facilitate the collection and discharge of the gypsum deposited on the lower side of the second body 120.

That is, the raw material supplied through the supply unit 111 may be a liquid raw material in which the waste paper and water are mixed at a ratio of 1: 100, and when the ink floating on the upper side is removed, It can be separated into a liquid raw material including cellulose and a goto corresponding to paper filling. At this time, the goto is settled to the bottom surface of the first body 110 due to the specific gravity, and is collected through the narrowing first body 110 and discharged through the second valve 115 and the second discharge portion 116, . At this time, the second sensor part 132 is formed on the second discharge part 116 to sense the deposition state of the goto.

The first valve (113) and the first discharge part (114) are configured to discharge only the liquid raw material containing cellulose except for the god component, which is disposed on the upper side of the goto layer to be precipitated.

At this time, in order to float the ink component in the raw material supplied to the first body 110, fine air bubbles are supplied and the air bubbles are dispersed smoothly for a predetermined period of time, A fixed blade 117 for stirring is formed.

The second body 120 is coupled to cover the upper portion of the first body 110. The lower body of the second body 120 is surrounded by the lower body of the first body 110, A receiving portion 121 for receiving the liquid and a third discharging portion 122 for discharging the accommodated upper liquid.

In addition, a first sensor unit 131 is installed inside the second body 120 for detecting the level of the raw material and the ink component, A third sensor unit 140 for sensing the pH of the supplied raw material is installed.

In addition, a diffuser 160, which generates fine bubbles to promote floating of ink components mixed in the raw material, is installed at the lower inner side of the first body.

FIG. 3 is a cross-sectional view illustrating the structure of a diffuser according to a preferred embodiment of the present invention. Referring to FIG. 3, the diffuser 160 includes an air supply unit 161 for basically pushing and discharging air like a blower, And a diffuser 160 is coupled to the blowing pipe 162 to distribute and supply high-pressure air into the processing tank 120.

Specifically, the diffuser 160 includes a connecting portion 164 formed with an exhaust port coupled to the blowing pipe 162 to discharge air, an opening / closing portion 165 coupled to the connecting portion 164 to be opened by air pressure and closed by water pressure, And a diffusion part 166 coupled to an end of the connection part 164 and extending upward to diffuse the discharged air to a wide range.

The diffusion portion 166 includes a plurality of through holes, a guide member for preventing deformation, and a cover plate and a lower discharge hole formed with a cone for guiding bubbles to the outside at the center. The opening and closing portion 165 is formed along the side surface And an opening / closing plate having a plurality of upward projections formed therein is vertically moved so as to open and close the outlet.

In addition, an agitating unit 150 is provided to promote contact between the fine particles and the ink component supplied through the diffuser and to promote separation of the ink components in the raw material.

The stirring unit 150 includes a stirring blade 151 positioned on the upper side and the lower side of the fixed blade 117 and a rotating shaft 152 formed on the stirring blade 151 and a driving unit 152 for rotating the rotating shaft 152. [ (155).

Specifically, as shown in the figure, a driving unit 155 including an electric motor is provided outside the second body 120, and a rotating shaft 152 is vertically passed through the second body 120, A stirring blade 151 is installed at the lower end of the rotation shaft 152 to stir the raw materials contained in the first body 110 at a predetermined time and speed.

At this time, the stirring part 150 is formed at the same position as the fence part 112 outside the rotation shaft 152, and rotates independently or together with the rotation of the stirring wing 151 by the driving part 155 And an auxiliary blade 153 for inducing overflow of the upper liquid.

The auxiliary vane 153 serves to smoothly overflow the supernatant containing the ink component of the raw material contained in the first body 110. The surface of the raw material is stagnated from the lower side of the fence portion 112, So that when the ink component is not overflowed, fine fluctuations are generated on the surface so that the residual ink component can be discharged.

The auxiliary vane 153 may be installed on the rotary shaft 152 to rotate together with the stirring vane 151. The auxiliary vane 153 may be installed to surround the rotary shaft 152, And the auxiliary wing 153 is provided outside the auxiliary rotation shaft 154 so that only the auxiliary wing 153 rotates while the stirring wing 151 is stopped . Accordingly, the driving unit 155 is configured to separately rotate the rotation shaft 152 and the auxiliary rotation shaft 154.

In addition, since sodium hydroxide is used together with water as a medicine for swelling and bleaching of waste paper mixed with raw materials, sodium hydroxide is contained in the storage part 171 for supplying the sodium hydroxide to the first body 110 according to a control signal A water supply unit 172 for supplying water to the first body 110 in accordance with a control signal and a controller 170 for generating a control signal reflecting the detection result of the third sensor unit 140, And a concentration adjusting unit 173 for controlling the water supplying unit 172.

This is because the remaining ink layer not discharged through the first sensor part 131 is prevented from being discharged to the outside of the first body part 110, And when it is confirmed that the ink remains in the vicinity of the portion 112, the level of the raw material is raised through an artificial water supply, thereby discharging the residual ink component smoothly.

In addition, components other than the ink may be discharged together through the first discharge unit 114, so that in the present invention, the auxiliary treatment tank 180 for treating the auxiliary treatment tank 180 is installed on the first discharge unit 114 side .

The raw material containing ink is introduced into the first space 182 and the bottom portion is inclined downward toward the second space 183 so that the raw material flowing into the first space 182 flows into the first space 182, 181 to the second space 183 through the lower portion of the second space 183.

At this time, since the ink component floating in the water stays in the first space 182 due to the partition 181, the ink component floating on the surface of the first space 182 can be primarily removed through a separate removing means A fifth discharge portion 187 having a fifth valve 188 for discharging an ink component is formed in the first space 182 and the fifth discharge portion 187 corresponding to a position where the fifth discharge portion 187 is formed A fourth sensor unit 185 including a conductivity sensor for sensing the oil layer in the first space 182, that is, the ink component, is installed.

In addition, the control unit 190, which will be described later, detects the accumulated ink component through the fourth sensor unit 185 and opens the fifth valve 188 so that the ink component can be automatically separated and discharged.

In addition, as the bottom surface of the auxiliary treatment tank 180 is inclined downward toward the second space 183, the waste paper component that sinks into the water flows along the flow and bottom slope of the effluent water to the bottom surface of the second space 183 And a separate discharge is performed through the fourth discharge portion 184 where the fourth valve is formed. The processing in the auxiliary processing tank 180 may require some time, and therefore, it needs to be manufactured to have a sufficient capacity.

A supply pump 190 for supplying water in the second space 183 to the first body 110 is provided separately when the auxiliary treatment tank 180 is provided, May be connected to the supply part (111) or the water supply part (172).

FIG. 4 is a block diagram illustrating an electrical configuration and a connection relationship according to a preferred embodiment of the present invention. The control unit 190 is provided with a control panel in the form of a control panel for controlling various electrical configurations supplied from outside.

Specifically, the first sensor unit 131 reflects the sensed result, and controls the supply unit 111 to supply the raw material to the first body 110. If necessary, the water supply unit 172 is controlled, The level of the raw material accommodated in the container 110 can be raised. In addition, the second valve (115) may be opened to reflect the detection result of the second sensor unit (132), and the goto may be automatically discharged. The pH of the raw material contained in the first body 110 is adjusted through the first portion 173 to adjust the level of the raw material in connection with the first sensor portion 131 if necessary, 113 and the second valve 115 are opened.
