The technical contents of the present invention will be described below by way of specific embodiments, and those skilled in the art can easily understand the advantages and effects of the present invention by the contents disclosed in the present specification. However, the creation can also be implemented or applied by other different embodiments.

It is to be understood that the structure, the proportions, the size and the like of the drawings are only used in conjunction with the disclosure of the specification for the understanding and reading of those skilled in the art, and are not intended to limit the implementation of the present invention. The conditions are limited, so it is not technically meaningful. Any modification of the structure, change of the proportional relationship or adjustment of the size should remain in this book without affecting the effectiveness and the purpose of the creation. The technical content revealed by the creation can be covered. In the meantime, the terms "upper" and "side" as used in the specification are merely for convenience of description, and are not intended to limit the scope of the creation of the invention, and the relative relationship is changed or adjusted. Under the technical content of substantive changes, it is also considered to be the scope of implementation of this creation.

The waste reuse mentioned in this creation refers to the reuse of waste epoxy resin produced by the semiconductor packaging and testing factory. The waste epoxy resin is also called waste molding compound in the packaging industry. In terms of the quality of concrete materials, CNS 1240 concrete pellets have detailed specifications for pellet quality. In addition, the wear rate test of pellets (CNS 490 Los Angeles mold loss test) is widely used as a source of similar minerals. The relative quality of the indicator. The main components of waste epoxy resin are cerium oxide (SiO ₂ ) and epoxy resin (Epoxy). The results of SGS test show that the wear rate of Los Angeles is only 4.0%, which is far better than the minimum required standard of 40%. Compared with the general natural pellets, the Los Angeles wear rate is 15%~25%. Therefore, in terms of pellet strength, the waste epoxy resin can be applied to concrete products, and the natural pellets can be replaced by appropriate proportions.

In the brick making process, the pellets need to be filled with sufficient cement slurry to mix the pellets during the mixing process, so as to provide lubrication between the pellets during mixing and reduce the interaction between the pellets. The ideal pellet is a particle that is similar in shape to the sphere. If the surface is angular or flat and slender, the quality of the tile will be significantly disturbed, that is, more cement slurry is needed to wrap each particle surface. This work proposes the reuse of waste epoxy resin, and also considers how to achieve the better particle size appearance and distribution through the pulverization technology. In addition to maintaining the same strength as the original natural granules, it can also reduce the amount of cement through technology introduction. This will reduce costs.

Please refer to Figure 1 for the structural diagram of the concrete floor tile manufacturing equipment of this creation. To put it simply, the concrete floor tile manufacturing equipment 1 of the present invention is used for manufacturing concrete products, such as floor tiles, and the waste epoxy resin is mainly used to replace the natural pellets in the concrete products in an appropriate proportion, but the concrete products are of various types, and the creation is based on floor tiles. For example, the technology of this creation can still be applied to other concrete products under the specifications of other concrete products. The application of this creation is not limited to concrete tiles.

As shown in Fig. 1, the concrete floor tile manufacturing apparatus 1 of the present invention includes a first crusher 10, a screw conveyor belt 11, a first storage tank 12, a second storage tank 13, a third storage tank 14, and a mixer 15. , brick machine 16 and fourth storage tank 17.

When the concrete floor tile manufacturing equipment 1 is in operation, the first crusher 10 is used to crush the waste epoxy resin 100 from the packaging factory, so that the waste epoxy resin 100 becomes a compression molding rubber pellet having a particle size of 25 mm to 150 μm, and passes through the screw. The conveyor belt 11 is conveyed to the first storage tank 12 for storage.

In order to make the die-cast rubber pellets meet the brick making requirements, the first crusher 10 is provided with a crushing cutter, wherein the cutter surface of the crushing cutter is at an angle of 45 degrees, thereby making it possible to uniformly break the waste epoxy resin 100. The shape and size are required, and details such as the cutter and the die rubber pellets will be described in detail later.

In addition, although the first crusher 10 has been crushed and polished for the waste epoxy resin 100, in order to ensure that the molded rubber pellets formed after the waste epoxy resin 100 is broken conform to the brick making specification, the screw conveyor belt 11 is transferred. When the rubber pellets are molded, the screw conveyor belt 11 and the molding rubber pellets are also rubbed, thereby performing re-polishing on the molding rubber pellets.

The second storage tank 13 is for storing natural pellets, the natural pellets used may be bipartite, the third storage tank 14 is for storing cement, and the fourth storage tank 17 is for storing water. Natural pellets and cement are the materials of existing concrete floor tiles. In this creation, the molded pellets are replaced with natural pellets in an appropriate proportion, thereby achieving the purpose of recycling the waste epoxy resin 100.

In order to make the size of natural pellets meet the requirements of brick making, natural pellets Before the material is stored in the second storage tank 13, a second crusher (not shown) connected to the second storage tank 13 may be provided, which can be used for pre-crushing the natural pellets and storing them.

The mixer 15 is connected to the first storage tank 12, the second storage tank 13, the third storage tank 14, and the fourth storage tank 17, and the mixer 15 is for receiving the molding rubber pellets from the first storage tank 12, The natural pellets of the second storage tank 13, the cement of the third storage tank 14, and the water stored in the fourth storage tank 17 are mixed and stirred to become a floor tile material for subsequent use in making the floor tiles.

In order to obtain a suitable material ratio, the first storage tank 12, the second storage tank 13, and the third storage tank 14 are respectively provided with scales for measuring the weight of materials provided by the respective storage tanks.

The brick making machine 16 is connected to the mixer 15, and the brick making machine 16 is used for pressing the floor tile material, so that the floor tile material is pressed, cured, etc., and finally becomes the concrete floor tile 200.

Please refer to Figure 2 for the execution flow chart of the concrete floor tile manufacturing equipment of this creation. In simple terms, when the waste epoxy resin is sent to the brick making equipment, it is first confirmed whether the waste epoxy resin is a usable material. If it is not, the brick cannot be made. If it is, it can be used for the brick making process.

The waste epoxy resin is first crushed by the crusher and transferred to the first storage tank through the screw conveyor belt, and the natural pellets are also broken by another crusher, or can be transferred to the second storage material through the screw conveyor belt. The groove, the screw conveyor belt can re-polish the crushed material to ensure that the quality of the pellet after crushing is suitable for the floor tile, that is, the good polished surface helps to better mix the die rubber pellet with the cement powder and the bipartite. Ash may be produced during the crushing process Dust and exhaust gas can be absorbed by the cyclone dust collector and collected by the bag dust collector and discharged under the compliance specification (exhaust gas detection). In addition, the crusher can also be replaced by a pulverizer or a grinder.

In addition, the third storage tank is storage cement, which is one of the existing materials of the concrete floor tile, and the first to third storage tanks can respectively be provided with weighing facilities for measuring the weight of the materials provided by the respective storage tanks. In the specific implementation, a weight system can be set, the predetermined ratio weight of each material is calculated, and the weight demand message is transmitted to the weighing facility of each storage tank, so that the weighing facilities of each storage tank can be used by the storage tank. Get the material of the required weight.

The above materials can also be conveyed to the mixer (ie, the mixer) through the screw conveyor belt, and if there is exhaust gas in each of the storage tanks, they can also be discharged and collected by the bag dust collector.

The fourth storage tank stores water, and the same amount is obtained through the counterweight system. After that, it can be controlled by a solenoid valve to introduce the required amount of water into the mixer (ie, the mixer).

After the above materials and water are stirred by the mixer, the brick making materials required for brick making are formed, and finally, the brick making operation is performed by the brick making machine, and finally, the high-pressure concrete floor tiles described in the present invention can be obtained through the health maintenance program. In addition, the brick making machine may be an oscillating or high pressure extrusion brick making machine, which is well known in the art and will not be described in detail.

Figure 7 is a structural sectional view of the concrete floor tile of the present invention. As shown in the figure, the high-pressure concrete floor tile of the present invention can be composed of waste epoxy resin, natural pellets, cement and water to form the body 71 of the concrete floor tile, wherein, natural 0.1%-100% of the volume ratio of the pellets is replaced by waste epoxy resin, in other words, from a very small amount of substitution to a complete substitution, and the waste epoxy resin is broken. After crushing, a molding die pellet of a size of 25 mm to 150 μm is formed.

In addition, the concrete floor tile further includes a fabric layer 72 covering the body 71, and the fabric layer 72 may be composed of a proportion of natural pellets and cement.

This work replaces the natural pellets (bipartite) with waste molding compound (waste epoxy resin) in different volume ratios, where the volume substitution ratio is 20%, 40%, 60%, 80%, 100. % is tested, and the original formula 0% is used as a control. The substitution ratio operation is performed by the specific gravity conversion, and the volume substitution substitution of the estimated specific gravity of the waste molding compound mixture is applied to all the bricks of various sizes. Among them, the water-cement ratio is in the range of 0.25-0.45, and the cement powder can be replaced by other cementing materials (such as fly ash and hearthstone), and the following table design can be used for all brick sizes.

It can be seen from the above that different volume substitution ratios can be made into concrete tiles of different composition, which can appropriately reduce the manufacturing cost of the tiles.

Please refer to the third figure, which is a schematic diagram of the crusher and screw conveyor belt of the concrete floor tile manufacturing equipment of the present invention. As shown in the figure, the front end equipment combination in the concrete floor tile manufacturing equipment of the present invention, the waste epoxy resin is transported to the first crusher 10 through the conveyor belt 20 for crushing, and the exhaust gas in the crushing process can be collected by the cyclone dust collector 30. After the waste epoxy resin is crushed, it becomes a compression molding rubber pellet, which can be transported to a storage tank (not shown) through the screw conveyor belt 11.

As mentioned above, the subsequent mixer and brick making machine are the basic equipment of the existing brick making program, so the illustration only draws the front section equipment, wherein the first crusher 10 has a specially designed cutter for crushing the waste epoxy resin and Polishing, this is the first stage polishing and physics.

After the first stage polishing and pulverization physical method is completed, the pellets are introduced into the screw conveyor belt 11, and the screw conveyor belt 11 conveys the first crushed pellets to the storage tank, and the screw conveyor belt 11 will be conveyed during the conveying process. The pellets collide to produce a polishing effect, that is, the pellets are rubbed and polished with the transmission bearing when the screw conveyor belt 11 is conveyed, so that when the first crushing is avoided, a small amount of unpolished pellets are sent to the storage tank.

Please refer to Fig. 4, which is a schematic diagram of the tool setting in the crusher of the concrete floor tile manufacturing equipment of the present invention. In general, the crusher can be divided into crush type (including blade type) and crush type. However, such equipment will cause the surface of the crystal to crack and form a smooth and smooth surface when the material is crushed and broken, resulting in the shape of the pellet. It does not meet the requirements of brick making, and there are also eccentric and centrifugal impact crushing equipment. However, due to the large amount of dust generated during the crushing operation, the bearing is easily damaged, and the problem of excessive pellets appears. Therefore, this case proposes a double angle cutter to overcome the crushing problem.

As shown in Fig. 4, the double angle tool is used in the crusher to break the waste epoxy resin. The cutters 101 and 102 in the figure are double angle cutters. The bottom of the crusher is provided with a screen 103, and the epoxy resin is discarded. When it is crushed and becomes a molded rubber pellet, its size can be dropped through the screen 103 if it meets the requirements.

In short, the waste epoxy resin can be crushed by, for example, a crusher, a pulverizer, or a grinder. If the waste epoxy resin is to be broken into a certain particle size range, for example, a size of 2-4 mm, the size of the mesh 103 can be selected. A 2 mm screen size is added upwards, for example 5 mm for crushing, and a 5 mm screen is broken to obtain a very average granule of 2-4 mm, while the 2-4 mm size is within the fine particle range of CNS 1240 concrete pellets.

Although the thickness of the pellets used for concrete tiles can be 25mm, 19mm, 12.5mm, 9.5mm, 4.75mm, 2.36mm, 1.18mm, 600um, 300um, 150um, etc., the advantage of choosing a 5mm screen is that the pellets are broken. The strength is stronger overall, and the broken shape is elliptical (this is better for brick making). Compared with the flat strip, it is easy to be broken when testing compression and bending resistance. Elliptical compression test When the material is pressed up and down, it is not easy to have a breakage condition.

In addition, an automatic control switch is used under the cutters 101 and 102 to control the electromagnetic switch in the crusher. When the operation is performed, the residence time is about 2 seconds, and the gate is opened to put the pellets into the 5 mm screen. The purpose of staying for 2 seconds is to use the waste ring. Oxygen tree The smooth surface of the grease is thoroughly polished again to ensure that the quality after crushing meets the requirements of the tile. In general, the broken waste epoxy resin may have a particle diameter of about 2-4 mm, preferably an average of 2.36 mm, and the crushed compression molding rubber pellets may have a particle size ranging from 25 mm to 150 um, and the above applies to the floor tiles. Manufactured, this can be adjusted according to different strength requirements.

Please refer to Figures 5A and 5B for a schematic diagram of the tool angle in the crusher of the created concrete floor tile manufacturing equipment. Please refer to Figure 4 together. In order to achieve better crushing effect, the cutters 101 and 102 can be designed with double angles on the side of the blade 1011. The first face is at a 45 degree angle, and the second face is at a 55 degree angle. In the detail view A shown in the figure, the waste epoxy resin of various appearances such as long strips is broken into an elliptical shape by a chamfering method. Through the above-mentioned design of the blade surface of the tool as a double angle, the waste resin can be broken into the size and shape of the pellet suitable for the concrete floor tile.

Please refer to Fig. 6, which is a step diagram of the method for manufacturing the concrete floor tile of the present invention. As shown, in step S61, natural pellets, cement, and water are provided. Natural pellets, cement and water are the basic materials of concrete products. This creation is to replace some natural pellets with waste epoxy resin, so as to achieve the purpose of recycling epoxy resin.

In the specific implementation, the natural pellets such as bipartite can be transported to the feeding table, transported to a storage tank by a conveyor belt or a screw conveyor belt, and the cement is poured into another storage tank by feeding. Temporary storage, water can be piped to other storage tanks for temporary storage.

In step S62, the waste epoxy resin is sent to a crusher to perform a crushing operation to produce a molding die pellet having a particle size of 25 mm to 150 μm. Specifically, the waste epoxy resin has various shapes, sizes and sizes. In order to conform to the internal material specification of the tile, it is necessary to send the waste epoxy resin to the crusher to perform the crushing operation to change the waste epoxy resin into millimeter or micrometer. The die-cast rubber pellets and the die-cast rubber pellets may have a size of 25 mm to 150 μm.

In the specific implementation, the waste epoxy resin is transported to the crusher feed table, and the waste epoxy resin is transported to the crusher by the conveyor belt for crushing operation. The crushed particle size is millimeter, and the sieve size is used to obtain the particle size. The uniform size of the millimeter grade can range from 25mm to 150um, and the waste epoxy resin after being crushed is temporarily stored in the screw conveyor belt storage tank.

In step S63, the molding die pellet, the natural pellet, the cement and the water are stirred and mixed according to a predetermined ratio to become a tile material. According to the predetermined ratio of each raw material, the weighing equipment can be weighed and fed under the auxiliary storage tanks, and transported by the conveying facility to the mixing tank of the mixer. The mixer can synchronously enter the water, and the electromagnetic valve can be used to control the water intake. Then, the mixing industry is executed, in which the fabric layer and the body of the floor tile have their proportions.

In step S64, the floor tile material is pressed to become a concrete floor tile. After the completion of the aforementioned mixing industry, the high-pressure concrete floor tile can be pressed into the brick making machine by the conveying facility, and the pressed high-pressure concrete floor tile is placed on the PVC board.

In step S65, the concrete floor tile is subjected to maintenance work to obtain a finished tile product. The pressed high-pressure concrete floor tile is the finished concrete floor tile after the 8-hour steam curing or 48-hour air curing operation.

In summary, the concrete floor tile and concrete floor tile manufacturing equipment of the present invention can mix the waste epoxy resin produced by the packaging industry into the concrete floor tile to replace the original natural material in the concrete floor tile, wherein the waste epoxy resin The crusher is crushed into a size of 25mm-150um die-cast rubber pellets, so the first crusher cutter has a double angle design, and the screw conveyor belt for conveying the die-cast rubber pellets has a polishing effect due to friction, thereby avoiding the problem of the particle size of the concrete floor tile. Lead to poor quality. Through the brick-making technology of the concrete floor tiles of this creation, the waste epoxy resin of the packaging industry can be reused, and the cost of the bricks can be reduced, so that the waste of the packaging industry has the utilization value.
