Description

Technical Field

[0001] This utility model relates to a flame-retardant processing device for flame-retardant foam, belonging to the field of foam processing technology. Background Technology

[0002] Foam treated with flame retardants exhibits excellent properties and is widely used, including thermal insulation, sound insulation, shock absorption, lightweighting, high strength, and airtightness. This allows for its widespread application in construction, aircraft, transportation equipment, and electronics. However, existing spraying equipment has shortcomings; the sprayed flame retardant may not completely adhere to the foam, with a small amount escaping as mist or droplets into the surrounding environment, potentially harming the health of those nearby. Therefore, minimizing the release of flame retardant into the environment during the spraying process is a crucial technical problem that needs to be solved by those skilled in the art.

[0016] See appendix Figure 1-3As shown, the flame-retardant processing device for flame-retardant foam in this embodiment includes an unwinding mechanism 1, a winding mechanism 2, a first cover group 3, an infusion pipe 25, a plurality of nozzles 26, a main pipe 5, and a purification device. The first cover group 3 includes a pair of oppositely arranged cover bodies 23, a brush 24, and an exhaust pipe 19. The edge of the cover body 23 is connected to the brush 24, and the end of the cover body 23 is connected to the exhaust pipe 19. The infusion pipe 25 is connected to the cover body 23, and the plurality of nozzles 26 are sequentially connected to the infusion pipe 25. One end of the nozzle 26 extends into the interior of the cover body 23. The exhaust pipe 19 is connected to the main pipe 5, and the main pipe 5 is connected to the purification device.

[0017] Foam 17 is discharged from the unwinding mechanism 1 and finally wound up by the winding mechanism 2. A first shroud assembly 3 is installed between the unwinding mechanism 1 and the winding mechanism 2. Foam 17 passes between a pair of shrouds 23 and its surface dust is swept away by brushes 24. Flame retardant is sprayed onto foam 17 from nozzles 26 via infusion pipe 25. The purification equipment collects the gas inside the first shroud assembly 3 through the main pipe 5 and the exhaust pipe 19, purifying any small amount of flame retardant that has not completely adhered to foam 17. Clean air enters between the pair of shrouds 23 through the gaps in the brushes 24. The air inside the pair of shrouds 23 flows in one direction. This prevents the gas containing flame retardant from escaping from between the pair of shrouds 23 into the surrounding environment, protecting the health of people in the vicinity.

[0018] The present invention is further configured as follows: the purification equipment includes a cylinder 6, an air inlet pipe 7, a fan 8, a motor 9, a temporary storage hopper 12, a valve 13, and a discharge pipe 14; one end of the air inlet pipe 7 is connected to the main pipe 5, and the other end is connected to the tangent at the top of the cylinder 6; the fan 8 is fixedly installed at the top of the cylinder 6, the air inlet 11 of the fan 8 extends into the center of the cylinder 6, the exhaust port 10 of the fan 8 is connected to the outside, and the motor 9 drives the fan 8 to rotate; the temporary storage hopper 12 is connected to the lower end of the cylinder 6, the discharge pipe 14 is connected to the lower end of the temporary storage hopper 12, and the valve 13 is located in the middle of the discharge pipe 14.

[0019] The motor 9 is started, driving the fan 8 to run. The air inlet 11 of the fan 8 draws air from the cylinder 6, creating a negative pressure inside the cylinder 6. Air from inside the first hood group 3 enters the cylinder 6 through the extraction pipe 19, main pipe 5, and inlet pipe 7, rotating inside the cylinder 6. Flame retardant droplets collide with the inside of the cylinder 6 and fall along the inner wall of the cylinder 6 into the temporary storage hopper 12. Air without flame retardant gathers at the center of the cylinder 6 and is output to the outside by the fan 8. The valve 13 is opened, and the flame retardant is discharged through the discharge pipe 14. In other embodiments, the purification equipment can also be a spray tower or an activated carbon adsorption tower.

[0020] To facilitate the alignment of the first cover assembly 3 with the foam 17, the present invention is further configured such that: a support is connected to the first cover assembly 3, the support including a base plate 15, a connecting plate 16 and a vertical plate 18, the two ends of the connecting plate 16 are respectively connected to a base plate 15, and several vertical plates 18 are vertically connected to the base plate 15, the vertical plates 18 being connected to the cover body 23.

[0021] In order to maintain the balance of the two sides of the cover 23, the present invention is further configured such that there are two upright plates 18, and the air extraction pipe 19 passes through the middle of the two upright plates 18.

Preferably, the longitudinal direction of the elongated hole 20 is vertical. By loosening the nut 22, the screw 21 slides to another position in the elongated hole 20. Then, the nut 22 is tightened to fix the elongated hole 20 and the screw 21. This achieves the purpose of adjusting the distance between the pair of covers 23.

[0023] To accelerate the drying of the flame retardant, this invention is further configured such that the flame retardant processing device for the flame-retardant foam also includes a second cover group 4, which has the same structure as the first cover group 3; a halogen lamp tube 27 is installed in the cover body 23 of the second cover group 4; and a reflector 28 is connected to the inner wall. The light emitted by the halogen lamp tube 27 irradiates the surface of the foam 17, causing the surface of the foam 17 to heat up and the flame retardant to dry more quickly.
