Flame retardant injection device {INCOMBUSTIBLE LIQUID INJECTION DEVICE}

The present invention relates to an apparatus for injecting a flame retardant into styrofoam used as a building material or a filling material of a sandwich panel, in particular, to spread the flame retardant injected into the styrofoam evenly inside the styrofoam and at the same time to dry well and flame retardant treatment time It relates to a flame retardant injection device for shortening.

In general, styrofoam, which is used as a building material or as a sandwich panel filler, is a foam-molded synthetic resin that causes fires to spread very quickly in case of fire and burns a lot of toxic gases, which intensify human injury.

In order to solve this problem, a treatment technology for injecting a flame retardant into a styrofoam has been introduced.

However, in the conventional flame retardant injection treatment technology, the flame retardant injected into the styrofoam does not evenly penetrate into the liquid and accumulates in one place, and a cured film is formed on the surface to prevent contact with air, thereby drying the internal flame retardant. It took a long time.

In this case, the uncured flame-retardant liquid still remains in the inside, and when the styrofoam is transferred, the remaining liquid inside is leaked to the outside of the styrofoam, and the product value of the styrofoam decreases. And even though the flame retardant is cured even if dried, the flame retardant is solidified in the form of agglomeration with each other.

Accordingly, an object of the present invention is to provide a flame retardant injector for injecting the flame retardant injected into the styrofoam evenly spread inside the styrofoam to dry well and shorten the flame retardant treatment time.

In the flame retardant injection device, the present invention for achieving the above object, the styrofoam (A) supplied from the styrofoam supply unit 4 constitutes the flame retardant processing unit 6 and the air injector 10 and the air injector 12 Sequentially passing through the injection into the liquid injector (10) and the flame retardant is injected, the air injector (8) located in the rear blows air into the place where the perforated and flame retardant is injected styrofoam (A) Evenly spread the flame retardant is injected into the interior, it is characterized in that the flame retardant injected from the drying unit (8) to quickly dry.

The present invention has the effect that the flame retardant injected into the styrofoam evenly applied to the interior of the styrofoam evenly without increasing the flame retardant treatment process time of the styrofoam and can also shorten the drying time of the flame retardant.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a front sectional view of the flame retardant processing unit 6 having the gist of the present invention, FIG. 3 is a plan sectional view of FIG. 2, and FIG. 4 is a side sectional view of FIG. 5 is a perspective view of the main parts of the chain conveyor 24 in the flame retardant treatment unit 6.

Flame retardant injection apparatus 2 applied to an embodiment of the present invention includes a styrofoam supply unit 4, a flame retardant treatment unit 6 and a drying unit 8, as shown in FIG. (6) is the summary structure part of this invention.

The flame retardant treatment unit 6 is installed to extend the chain conveyor 24 in the longitudinal direction, and the styrofoam supply unit 4 and the drying unit 8 are separately installed belt conveyors 25b, 25c, styrofoam supply unit The styrofoam A in (4) is transferred to the flame retardant treatment part 6 and the drying part 8.

In the styrofoam supply unit 4 according to an embodiment of the present invention, the styrofoams (A), which are not treated with flame retardant, are erected to stand on each other and placed on a plurality of supply chain belts (25a) installed in the width direction, and are waiting for the styrofoam ( A) is transferred to the conveying belt conveyor 25b one by one through the supply chain belt 25a, and the styrofoam A is supplied to the flame retardant treatment unit 6 through the conveying belt conveyor 25b.

The styrofoam (A) supplied to the flame retardant treatment unit 6 is passed by the chain feeder 24 in the flame retardant treatment unit 6 while sequentially passing through the liquid injector 10 and the air injector 12. The liquid injector 10 drills the needle holes on the wall of the styrofoam (A) and injects the flame retardant into the needle hole, and the air injection unit 8 located behind the flame retardant is injected after the drilling. Blow air into the seat to ensure that the flame retardant injected into the styrofoam (A) is evenly penetrated.

2 to 4 together, the flame retardant processing unit 6 is a liquid injector 10 and the air injector 12 in the housing 22 located above the main body frame 20 at a predetermined interval before and after It is configured to be installed. Each of the liquid injector 10 and the air injector 12 has the supports 40-1 and 40-2 installed in the longitudinal direction so that the feed control can be performed, and the operation accommodated in the pair of supports 40-1 and 40-2. The wall 60-1, 60-2 has a structure provided so that a feed control is possible in the width direction.

Chain conveyor 24 for transferring the styrofoam (A) from the liquid injector 10 to the air injector 12 is installed in the longitudinal direction, but is installed in the upper and lower portions passing through the support (40-1) (40-2) Make a pair.

The upper and lower chain conveyor 24 has a configuration in which the attachment chain 26 is chained to the driving sprocket 30 and the driven sprocket 32, and is driven by the transfer servo motor 34 connected to the driving sprocket 30.

An encoder is mounted on the transfer servo motor 34 for driving the chain conveyor 24, and the encoder outputs a pulse signal generated when the transfer servo motor 34 is driven to a controller (not shown). The controller checks the pulse signal received from the encoder and calculates the exact moving distance of the styrofoam A moved by the chain conveyor 24. The controller that calculates the moving distance of the styrofoam A sends a driving time point of the first servo motor 44 and the second servo motor 54 which will be described later. The first servomotor 44 is a servomotor for positioning the supports 40-1 and 40-2 in the longitudinal direction, and the second servomotor 54 is in the supports 40-1 and 40-2. It is a servomotor which controls the operation walls 60-1 and 60-2 in the width direction.

The upper and lower chain conveyor 24 is an attachment chain, and the attachment chain has a structure in which the fixing needles 28 for transport are formed on the attachments 27 of the chain link 26, respectively. When the chain conveyor 24 of the attachment chain is driven, the transfer needle 28 transports the styrofoam (A) supplied from the styrofoam supply unit 4 precisely without slipping by piercing the upper and lower portions of the styrofoam (A) without slip. .

Meanwhile, the support body 40-1 of the liquid injector 10 reciprocates in the longitudinal direction by the front and rear reciprocating drive unit 50. The front and rear reciprocating drive unit 50 is fixed to the ceiling of the housing 22, the ball screw 54 connected to the drive shaft of the first servo motor 52 and the first servo motor 44 capable of forward and reverse rotation is fixed, The screw nut 56 is screwed to the ball screw 54, and the screw nut 56 is connected to and fixed to the support 40-1 positioned at the lower portion thereof. In addition, by installing the LM guide 80 in the lower portion of the support 40-1, the support 40-1 is guided by the LM guide 80 to stably reciprocate linearly in the longitudinal direction. The LM guide 80 may be provided in addition to both sides of the support.

 Therefore, when the first thermovoter 52 of the front and rear reciprocating drive unit 50 is operated under the control of the controller, the support 40-1 has the same speed as that of the styrofoam A driven by the chain conveyor 24. And advances a predetermined distance in the advancing direction and when the flame retardant injection is completed is quickly returned to the reverse, this operation is repeatedly performed under the control of the controller.

The working wall 60-1 accommodated in the support 40-1 is installed in a pair symmetrically to the left and right of the chain conveyor 24 as shown in FIG. 4, and the left and right working wall 60-1 is It reciprocates in the longitudinal direction by the left and right reciprocating drive part 70.

The left and right reciprocating driving unit 70 is fixed to the ceiling of the support 40-1, the ball screw 74 connected to the drive shaft of the second servo motor 72 and the second servo motor 72 capable of forward and reverse rotation is fixedly installed. The screw nut portion 76 is screwed to the ball screw 74, the screw nut portion 76 is configured to be connected and fixed to the operation wall (60-1) located in the lower portion. In the working wall 60-1, an accommodating space 62 for temporarily storing a flame retardant supplied from a flame retardant supply tank (not shown) is formed by a pressurizing action of the pressure pump P. The accommodating space 62 and The communicating needle 64 is fixedly arranged up, down, left and right on the front surface of the working wall 60-1. In addition, by installing the LM guide 81 in the lower portion of the working wall 60-1, the working wall 60-1 is guided by the LM guide 81 so as to stably perform the reciprocating linear movement in the left and right directions.

Therefore, when the second thermovoter 72 of the left and right reciprocating drive unit 70 is operated under the control of the controller, the working wall 60-1 moves quickly in a styrofoam A direction, that is, to the left and right directions, and then returns quickly. do. At this time, the needle 64 drills the needle hole into the styrofoam A as the working wall 60-1 moves, and at the same time, the accommodating space 62 is pressurized by the pressure pump P to the needle hole. After the injection of the flame retardant is filled through the injection needle 64 is repeated to perform the operation.

The first and second servo motors 52 and 72 operate at the same time by the signal of the control unit, so that the piercing of the styrofoam A and the flame retardant injection are performed while the styrofoam A is not stopped. It is possible. That is, the support body 40-1 moving by driving the first servo motor 52 of the front and rear reciprocating driving unit 50 is rearward at the same speed as the feeding speed of the styrofoam A which is transported by the chain conveyor 24. Since the operation wall 60-1 moving by the second servomotor 72 of the left and right reciprocating drive unit 70 is installed inside the support 40-1, the operation wall 60-1 This is because the needle 62 installed at the same also moves backward at the same speed as the styrofoam A. FIG.

As described above, when the injection and flame retardant injection are completed while moving at the same speed as the styrofoam (A) in the liquid injector 10, the first and second servo motors 52 and 72 quickly return by the reverse operation. After that, it waits for the next driving time. At this time, the styrofoam (A) continues to move backward at a constant speed, and the first and second servos waiting to calculate the moving distance of the control unit styrofoam (A) receiving a pulse signal from the encoder of the transfer servo motor (34). The next driving time is sent to the motors 52 and 72. Styrofoam (A) formed long in the front and rear direction by the repetitive operation of the first, second servo motors 52, 72 passes through the liquid injector 10 at a constant speed, the overall flame retardant treatment.

The injection needle 64 is a structure that minimizes wounds when puncturing the styrofoam (A) by cutting a portion of the liquid discharge port 64a in an oblique form as shown in FIG. The discharge outlet 64a is formed on both sides and formed in a hemispherical shape with the end blocked. The wound during styrofoam (A) is larger than that of FIG. 6A, but effective for even injection of flame retardant. .

Next, the air injector 12 installed at the rear of the liquid injector 10 is installed in a structure similar to the flame retardant inlet unit 10. However, in the liquid injector 10, the flame retardant was injected into the styrofoam A through the injection needle 64 by the pressure of the pressure pump P connected to the flame retardant storage tank (not shown), but in the air injector 12, the compressor was compressed. There is a difference that air is injected through the needle 64a by the pressure of (C).

The air injector 12 has the needle 64 is re-entry into the place where the puncture and flame retardant is injected in the liquid injector 10 and blows air to spread the flame retardant injected into the styrofoam A evenly. The encoder installed in the above-described transfer servo motor 34 outputs a pulse signal generated when the motor is driven to the control unit to calculate an accurate distance, and the control unit controls the first and second servo motors 52 of the air input unit 12. 72 is implemented by applying the driving timing.

Styrofoam (A) is a flame retardant treatment is carried out in the state of continuously moving at a constant speed without stopping the inside of the liquid injector 10 and the air injector 12, so that more flame retardant treatment is possible at the same time.

Air injector 12, as shown in Figure 7 (a) is further provided with a second, third air injector (12a, 12b) it is preferable that the air injection is made over a plurality of cars, more preferably the second, third Applying a strong air pressure gradually toward the air injector (12a) (12b) is effective in preventing the liquid from popping out to the maximum dispersion of the injected flame retardant. That is, when the air is blown at a strong pressure from the air injector 12 from the beginning, a large amount of accumulated liquid may be splashed out of the styrofoam (A).

In addition, in the case where one or more flame retardant treatment units 6 are provided as shown in FIG. 7B, the flame retardant treatment unit 6a avoids the perforated and flame-retarded positions in the primary flame retardant treatment unit 6. Once again you can add flame retardant treatment.

Styrofoam (A) is a liquid spread evenly inside the air injector 12 is finally dried while passing through the drying unit (8). The drying unit 8 is provided with a conveying belt conveyor 24b and transfers the styrofoam A passed through the flame retardant treatment unit 6 to be dried.

In the above description of the present invention, specific embodiments have been described, but various modifications can be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the claims and their equivalents.
