Abstract

The present invention is for the recycling of furniture and wood, and sprays compressed air and abrasion materials at the same time to impinge on the surface of the wood or furniture (painting surface) to remove paint and dirt due to the friction, furniture or wood to be repainted after removal It makes the surface beautiful, strengthens the adhesion of paint and shortens the drying time when repainting.

According to the present invention, the furniture and wood can be recycled economically and quickly by adjusting the type of wear material to be sprayed, the pressure of compressed air to be sprayed, and the size and shape of the spray nozzle according to various furniture or wood materials.

The abrasive material to be sprayed is mixed with soft abrasive materials such as walnut shell powder, corn flour, plastic media, and sawdust according to the characteristics of the wood and paint materials to be recycled, and hard abrasive materials such as aluminum oxide, sea sand, geumgangsa, and glass beads. By using it, remove the old painted surface and dirt without damaging the original condition of the wood.

Existing recycling methods are almost impossible to recycle due to the high cost of recycling because they are almost dependent on manual work, and cause greater problems in disposal by repainting thicker without surface treatment. By solving these problems, the present invention can reduce the consumption of large amounts of wood, reduce the economic cost and burden for the disposal of furniture and wood, and achieve environmental protection.

Description

The refinishing equipment of furniture and timber by spraying mixed abrasives for recycling}

The annual amount of waste wood is 10715,000m3, which is 1.2 times the total domestic consumption of wood and 9 times that of domestically produced wood. However, only about 30% of the recycled wood is available, and the recycling rate for furniture is far below that.

The main reason that furniture recycling is difficult is that processing costs for recycling are so close to the price of new furniture because relying on old, labor-intensive manual handling of old and painted surfaces. The purpose of the present invention is to solve the problem of the surface treatment work, which is the main cause of the high cost.

The present invention is a technique for surface treatment technology for furniture and wood recycling and the use of mixed abrasive materials for surface treatment. Existing furniture and wood surface treatment is an expensive and labor-intensive work method using cutting, sanding grinders or sand paper (Fig. 1), which requires a great deal of time and manpower to obtain a uniform and clean surface during the surface treatment of furniture. This avoids regeneration after surface reprocessing.

The purpose of the present invention is to solve problems such as resource depletion caused by excessive use of timber, economic burden due to imports, costs for the disposal of furniture and various pollutants (dioxine, etc.) generated at disposal (incineration). It is intended to provide a very economical, fast and environmentally friendly way for the recycling of wood and furniture that must be implemented to address.

According to the present invention, the composition of the mixed wear material for the surface treatment of wood and furniture and the degree of contamination of the wood or furniture (1) to be treated by the method of treating the mixed wear material by spraying (36) simultaneously with the compressed air (6), In the mixed wear material container 10 by adjusting the mixing ratio of the compressed abrasive material 8 and the mixed wear material 34 in which soft and hard wear materials are mixed according to the coating material, the thickness of the coating surface, the hardness of each wood, and the like. A device is provided in which the dropped abrasive and compressed air are sprayed through the air hose (26) to the spray nozzle (28).

Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows.

1 is a method used by refurbishing the surface of existing furniture, the type and shape of the furniture is a variety of sand paper (2) by hand to process the bent and uneven parts and the flat part using a sanding grinder (4) Remove paint and dirt. In addition, belt-type sand grinders are used for the surface treatment of large wood and plywood, but they are rarely used for the surface treatment for recycling.

Figure 2 shows a method of surface treatment of furniture and wood using a mixed wear material 34 and a hard wear material 24 according to the present invention, the compressed air (6) is a control valve with an air pressure gauge ( 8) to adjust the air pressure. Silo wear containers use two mixed and hard wear containers. The mixed abrasive 34 is introduced into the silo-type mixed abrasive container 10 through the upper inlet 14, and the discharge amount is controlled by the control valve 18. Compressed air and mixed wear material is injected into the nozzle 28 through the high pressure hose (26). The hard wear material is introduced into the silo-type hard wear material container 12 through the upper inlet 16 and the discharge amount is controlled by the control valve 20. Compressed air and hard wear material are injected into the nozzle 28 through the high pressure hose (26). Considering the type and characteristics of the existing coating material of the furniture (1) to be reprocessed, the thickness of the painted surface, and the hardness of the wood and wood of the furniture (1) to be reprocessed, the hard wear material (24) and the mixed wear material ( By selecting the use of 34) and controlling the amount of compressed air by adjusting the amount of use (8), it can be used regardless of the type of wood, the type and thickness of the coating material. It can be used freely regardless of the shape and size of the furniture because it can be used to increase the efficiency and the nozzle 30, the nozzle 30 with a small inner diameter, the nozzle 32 with a large inner diameter can be used.

3 is a cross-sectional view of the wear material according to the present invention, the silo type mixed wear material container 10 has a soft wear material (24) on the soft wear material 22-walnut shell powder, corn flour, plastic media, sawdust, etc.- Aluminum oxide, geumgangsa, sea sand, glass beads, etc. are mixed and poured into the inlet 14 is mixed with the compressed air through the outlet 40, the discharge amount can be adjusted by the valve (18). The silo type hard wear container 12 may also be used in the same manner as the mixed wear material container, but the outlet 42 of the hard wear material container is made smaller so that no damage is caused to the wood and the discharge amount is returned to the valve 20. You can adjust it.

4 illustrates the use of a nozzle 30 having a small inner diameter and a nozzle 32 having a large inner diameter when spraying a wear material according to the present invention to treat surfaces of furniture 1 of many types and sizes. In order to maximize the efficiency of the work together with the selection of wear materials and air pressure control shown in FIG. 2, the selection of the inner diameter of the nozzle suitable for the work is very important. In the case of FIG. If small, the nozzle 30 having a small inner diameter is used, and furniture having a large processing surface as in the case of (B) can increase the speed and efficiency of work by using the nozzle 32 having a large inner diameter.

Such a surface treatment apparatus can be conveniently and widely used for surface treatment of all furniture and woods as described above with high economy and speed.

As described above, the treatment of the surface of furniture and wood for recycling by using the device of the present invention is much more economical than the surface treatment method of furniture that is performed depending on the surface treatment method by the existing manual work. If the surface treatment is done by the existing method, the recycling cost is close to the purchase cost of the new furniture in some cases, thus avoiding the recycling, and by repainting it immediately without removing the old paint surface and the old time, The surface is unstable and easily peeled off.In case of disposal by incineration, all problems caused by the generation of deadly pollutants can be solved, which greatly improves the recycling rate of furniture and wood, thereby reducing the damage to forests and the cost of disposal. Can provide furniture and wood surface treatment technology to reduce the burden and burden.
