The present invention relates to a production apparatus for pulp mold products, and more particularly to a pollution-free pulp mold production apparatus that does not generate industrial waste.

Pulp mold refers to a product in which papers, cardboard, recycled paper or waste paper are pulped with water and stamped with a mold. Pulp mold products are food packaging materials that are easily broken or spoiled, such as fruits or eggs. It is also used for packaging electronics, electronic or mechanical parts, or for packaging or protecting fragile products such as glass.

These pulp mold products are produced by the pulp mold production equipment. The pulp mold production equipment is made by pulverizing high paper such as newspapers and pulping it into water and injecting it into the mold together with water. The pulp and water injected into the mold are dehydrated and removed. It is then dried to produce a pulp mold product.

Such a pulp mold apparatus can be largely classified into a dry apparatus and a wet apparatus.

Drying equipment is a method of producing pulp mold products by introducing pulp into the mold together with water, depressurizing and dehydrating water contained in the pulp mold, and then heating the pulp mold with a heating device provided in the upper and lower molds. The upper and lower mold presses the pulp mold for a certain time and heats the product, which makes the product firm and the front and rear sides have a smooth surface. However, it is expensive to heat the upper and lower molds by heating wires. Due to the use, the production cost increases, and the production speed is not fast, and there is a problem that mass production cannot be performed.

Wet equipment is to make pulp mold products through the drying process by injecting pulp mixed with water into the mold and depressurizing and dehydrating the water contained in the pulp from the mold to flow into the drying furnace and making pulp mold products through the drying process. The mass production is possible and the production cost is low, but a product having a smooth surface, such as a product by a dry device, has the disadvantage that it is not produced.

The present invention is divided into a wet device, mass production and production cost is low, as can be seen in a dry device, the front and back surface of the pulp mold products can be mass produced, and in particular, the water used in the entire process by recycling the industrial It is to implement a pollution-free pulp mold production facility that does not generate waste water and waste.

The pulp mold production apparatus for making pulp mold products by dipping the pulp formed by dissolving the waste paper in water with a mold requires a lot of water and has many problems in waste generation and waste water treatment by waste pulp.

The present invention seeks to reduce water by using only the amount of water used in the pulp mold product production apparatus for producing pulp mold products from the waste paper, and suppresses the generation of waste water and waste pulp mold to almost no industrial waste. The first purpose was to implement a non-pollution-free pulp mold production apparatus, and the second purpose was to provide a pulp mold production apparatus that minimizes the water used and reduces the production cost due to high efficiency and mass production.

The present invention having such a structure is described in more detail through the pulp mold manufacturing process and at the same time the operation of the present invention.

In producing pulp mold products, waste paper, raw wrapping paper, waste paper, etc., which are used as raw materials, enter the waste paper decomposition tank 11 with water, and the waste paper is soaked in water and stirred through a stirrer to pulverize the waste paper. do.

In pulping the waste paper, the concentration of pulp is 0.5 to 1% concentration of the pulp in water.

In this way, the pulping in the high resolution decomposition tank (11) is transferred to the pulp storage tank (12) through the pump, and the pulp storage tank (12) is gradually stirred for a predetermined time to dissociate the pulp and have cohesive force. The pulp supply tank 13 is transferred through the pump.

The pulp storage tank 12 or the pulp supply tank 13 is provided with an agitator to prevent the pulp from sinking and agglomeration, and to maintain a uniform concentration at all times.

The pulp and water of the pulp supply tank 13 flow into the water tank 15 through the supply pipe 18 and are laminated to a predetermined thickness on the lower mold 21 in the water tank 15 and then downward by the lower cylinder 24. The mold 21 is raised to come into close contact with the upper mold 31.

The lower mold 21 in the water tank 15 in which the pulp dissolved in the water is contained pulls the water and the pulp in the water tank 15 by the suction force of the vacuum tank 42 through the lower air pipe 22 and the lower mold 21. After collecting the pulp at a predetermined thickness, the lower mold 21 is raised above the water tank 15 by the lower cylinder 24.

The thickness of the pulp collected over the lower mold 21 is the thickness of the pulp collected over the lower mold 21 according to the opening and closing time of the vacuum opening valve 22B of the lower pipe 22 connected to the vacuum tank 42. Arbitrarily adjusted.

The pulp collected to a predetermined thickness above the lower mold 21 is raised above the water tank 15 by the operation of the lower cylinder 24, and at the same time, the upper mold 31 above the water tank is lowered to lower the mold 21. The upper and lower surfaces of the pulp collected at a certain thickness are pressed to make it smooth and flat.

Thus, the upper mold 31 presses the pulp on the lower mold 21 to form the pulp mold 10, and the upper mold 31 presses the pulp mold 10 on the lower mold 21 upward. The vacuum opening valve 22A of the upper pipeline 32 of the mold 31 is opened to be connected to the vacuum tank 42 so that the moisture remaining in the pulp mold 10 between the upper and lower molds 31 and 21 is maintained. When the pipe of the lower pipe 22 of the lower mold 21 is switched from the vacuum tank 42 to the air compression tank 41, the vacuum opening valve 22A is closed and the compressed air is closed. When opening the shut-off valve 22B, the pulp mold 10 on the lower mold 21 is separated from the lower mold 21 by compressed air supplied from the lower pipeline 22 and at the same time the upper cylinder ( 34 is operated to rise as the upper mold 31 in a state stuck to the upper mold (31).

Afterwards, the upper mold 31 moves the pulp mold 10 attached to the upper mold 31 while the cylinder fixing plate 38 moves on the rail 40 together with the movable operating table 36 for holding and fixing it. do.

The cylinder fixing plate 38 moving on the rail 40 moves above the conveyor belt 71 of the hot air dryer 70, and the upper mold 31 is moved by the upper cylinder 34 on the conveyor belt 71. When lowered, the upper vacuum tank open / close valve 32B of the upper air pipe 32 connected to the upper mold 31 is closed, and the upper compressed air tank open / close valve 32A is opened to pressurize the compressed air to the upper mold 31. The pulp mold 10 which is in close contact by dropping is dropped onto the conveyor belt 71 and transferred to the hot air dryer 70 through the conveyor belt 71 to be dewatered by upper and lower molds 31 and 21. Moisture that has not been heated is dried to complete the pulp mold 10 product.

As described above, the water mixed in the pulp adsorbed through the upper and lower pipes 32 and 22 connected to the upper and lower molds 31 and 21 is introduced into the vacuum tank 42 and stored. When the collected water is transferred to the treated water storage tank 46, the treated water introduced into the treated water storage tank 46 is introduced into the treated water transport tank 47.

As such, the treated water introduced into the treated water conveying tank 47 is partially supplied to the pulp supply tank 13 and the pulp storage tank 12 through the treated water conveying tank 47, and the high-fat decomposition tank ( It is reused as water in 11).

The treated water introduced into the treated water conveying tank 47 includes fine pulp pieces together with the water, thereby introducing the filtered tank 48 to remove the fine pulp from the treated water with a filtering network 48A. After entering the storage tank 49 is introduced into the water purification tank 50.

The purified water tank 50 is provided with a filtration filter (50A) for filtering again the water flowing into it to have only a very clean purified water free of foreign matter in the treated water.

As such, the purified water in the purified water tank 50 is discharged to the outside or recycled, and in particular, the vacuum tank 42 is supplied to the vacuum pump 43 which makes the vacuum state and reused as the sealing water of the vacuum pump 42 and the vacuum pump. The heated water (sealed water) containing air while cooling 43 is introduced into the purified water tank 50 again through the air separation tank 51.

The vacuum pump 43 describes the application of the vacuum pump 43 using water for sealing for airtight, but in the vacuum pump that does not use water for airtight, unlike this configuration has a separate design change .

However, in the present invention using a large amount of water, when a vacuum pump using water for airtightness is used, there is an advantage of not having to provide a separate water supply device for cooling the vacuum pump.

Pulp and water are simultaneously drawn in the water tank 15 at the vacuum pressure of the vacuum tank 42 to collect pulp at a predetermined thickness over the lower mold 21, and the lower mold 21 is discharged using the lower cylinder 24. (15) The pulp collected on the lower mold 21 when raised up is collected in a messy state to the edge of the lower mold 21. When it is dried, the edge of the pulp mold 10 product is not smooth and smooth. The pulp mold 10 of the dirty state is not produced.

Therefore, the pulp collected on the edge of the lower mold 21, it is necessary to remove it.

To this end, in the present invention, a washing water nozzle is attached to one side of the upper mold support 33, and the upper mold 31 is sprayed with the washing water when the upper mold 31 is moved onto the lower mold 21 to be pulp attached to the edge of the lower mold 21. Remove the debris.

As such, the water pressure of the washing water for washing the pulp residue attached to the lower mold 21 is sprayed through the low pressure washing nozzle 62 so that the washing water of low pressure is not washed away from the pulp collected on the lower mold. The washing water flowing into the nozzle 62 is supplied from the purified water tank 50.

In addition, when the pulp collected on the lower mold 21 is separated from the lower mold 21 and moved to the upper mold 31, a portion of the pulp is attached to the lower mold 21 surface and attached to the lower mold 21 surface. If the mesh of the mesh net (filtration net) is filled to fill the eyes of the bar periodically and not removed, the mesh net is filled so that the vacuum air and compressed air provided from the lower air pipe 22 do not function properly.

To this end it is provided with a high-pressure washing nozzle 61 for washing the lower mold 21 on one side of the upper mold support (33).

The high pressure washing water sprayed through the high pressure washing nozzle 61 removes the pulp pieces attached between the mesh nets on the lower mold 21 to clean the lower mold 21 and the lower mold by the high pressure washing water. 21) The cleaning will be done intermittently after a certain time.

As described above, the upper mold support 33 supporting the upper mold 31 has a low pressure washing nozzle 62 and a high pressure washing nozzle 61 for spraying the washing water into the lower mold 21 to clean the lower mold 21. The washing water used to receive the water is supplied from the purified water tank 50, and each washing water pipe having a pump 65, a high pressure valve 61A, and a low pressure valve 62A is provided in the middle of the washing water supply pipeline 52. .

In addition, the hot air dryer 70 having a conveyor 71 is provided with a plurality of gas burners to heat and dry the pulp mold 10 transported on the conveyor 71 to manufacture a finished product.

As the hot air generating source in the hot air dryer 70, an electric heater hot air fan may be used in addition to the gas burner.

The pulp mold 10 dried by passing through the hot air dryer 70 can be seen that the moisture is removed by the hot air to dry and shrink and warp so that the pulp mold 10 does not have a smooth surface.

In view of this, when the pressed pulp mold 10 is pressed into upper and lower molds 81 and 82 by pressing 80, the pulp mold is pressurized and hardened. The mold 10 is calibrated to a flat surface, and the heating mold 83 is provided inside the upper and lower molds 81 and 82 of the press 80 so that the pulp mold 10 can be heated faster and simultaneously with heating. ) Can be pressurized and calibrated.

As described above, the waste paper and the waste water and waste (waste Pulp) is produced little by little, and the produced pulp mold is to provide a pollution-free pulp mold production apparatus to produce a product with a clean and hard surface.

 The pulp mold product is a product made by mixing waste paper, waste cardboard, recycled paper, etc., with pulp and dipping it into a mold to recycle waste paper.

In particular, when pulp mold products are finally incinerated and treated, no pollutants such as dioxins are generated, and when they are landfilled, they become environmentally friendly because they are mixed with wood and decomposed after a certain period of time.

Such a pulp mold product is produced by dissolving the waste paper as a raw material in water, forming a mold with water and performing a dehydration and drying process. In the conventional art, a lot of water is required during the pulping process. Since most of the water is thrown away into the waste water, a large amount of waste water is generated and many wastes are generated. However, in the present invention, by reprocessing the water and reusing it, it provides a pollution-free facility without waste water generation and produces a good quality pulp mold in large quantities. It is a very useful invention to provide a facility to increase the.
