[0026] The primary permeation material distributor 1 includes a feed pipe 101, a material trough 102, a tilting plate 103, a baffle shaft 104, a front baffle 105, and a rear baffle 106. The material trough 102 is fixedly installed on the upper side of the middle part of the frame 20. The top of the material trough 102 is connected to the feed pipe 101. One end of the feed pipe 101 is connected to the outlet on the circulating material tank 5. The tilting plate 103 is fixedly installed at the bottom of the material trough 102. The tilting plate 103 is located on one side of the outlet on the material trough 102 and between the outlet on the material trough 102 and the feed pipe 101. There are two baffle shafts 104.

The two baffle shafts 104 are fixedly connected to the upper ends of the front baffle 105 and the rear baffle 106, respectively.

[0027] The negative pressure chamber 11 includes a negative pressure chamber body 1101, a vacuum suction groove 1102, a liquid seal valve 1103, a polytetrafluoroethylene (PTFE) sealing plate 1104, a circulating material pipe 1105, and a gas-liquid pipe 1106. A PTFE sealing plate 1104 is fixedly installed on the top of the negative pressure chamber body 1101. A vacuum suction groove 1102 is formed in the middle of the top of the PTFE sealing plate 1104.

The air outlet on the side of the negative pressure chamber 1101 is connected to one end of the gas-liquid pipe 1106. The other end of the gas-liquid pipe 1106 is connected to the inlet of the vacuum air-liquid separator 14. The air outlet on the vacuum air-liquid separator 14 is connected to the air inlet of the vacuum pump 18.

[0028] The working principle of this utility model is as follows: fireproof, waterproof, and high-strength inorganic materials are added into the mixing tank 17 and stirred by the internal stirring mechanism to form a fireproof, waterproof, and high-strength inorganic slurry. The fireproof, waterproof, and high-strength inorganic slurry is then transported to the circulating material tank 5 by the slurry pump.

[0029] Lightweight polystyrene foam material is placed on the secondary conveyor roller 6, which transports the polystyrene foam material to the perforated conveyor belt 9. The speed-regulating power pulley 13 is started, causing the perforated conveyor belt 9 to run at the set speed, driving the material to pass through the roller brush 7, the various permeable material distributors (first-stage permeable material distributor 1, second-stage permeable material distributor 2, third-stage permeable material distributor 3, and fourth-stage permeable material distributor 4), and the negative pressure chamber 11 in sequence.

[0030] When passing through the roller brush 7, the resistance of the polystyrene foam material causes the roller brush 7 to rotate, and its burrs 703 scratch the sealing film on the material surface. The material reaches the first-stage permeation material distributor 1. The feed pipe 101 transports the fireproof, waterproof, and high-strength inorganic mixed slurry material in the circulating material tank 5 to the material tank 102, so that the mixed slurry flows to the bottom of the material tank 102. The mixed slurry flows over the tipping plate 103 so that it is evenly distributed on the material surface through the outlet of the material tank 102. The front baffle 105 and the rear scraper baffle 106 scrape the residual permeation material on the board surface to keep the board surface with good permeability during secondary permeation. The same process is carried out in the second-stage, third-stage, and fourth-stage permeation material distributors (second-stage permeation material distributor 2, third-stage permeation material distributor 3, and fourth-stage permeation material distributor 4) in sequence to achieve four-stage material distribution and permeation.

[0031] When the material moves to the top of the negative pressure chamber 11, the vacuum pump 18 operates, drawing a vacuum into the negative pressure chamber 11 through the gas-liquid pipe 1106 and the vacuum gas-liquid separation tank 14. The vacuum suction groove 1102 on the top of the polytetrafluoroethylene sealing plate 1104 extracts the air from the material, allowing the permeated slurry to better fill the internal pores of the material. At the same time, the slurry falling into the negative pressure chamber 1011 will be transported back to the circulating material tank 5 through the circulating material pipe 1105 for reuse.

[0032] Throughout the process, the residual material collection tray 12 collects the fallen residual material, the rinsing device 1202 rinses it periodically, and the residual material returns to the circulating material tank 5 through the discharge port 1201 and the hose. The residual material collection tray 12 is located on the lower side of the negative pressure chamber 11 and is fixedly installed by the frame 20. Its discharge port 1201 is connected to the feed port of the circulating material tank 5 to ensure the recycling of residual material. Finally, the material after infiltration and treatment is further squeezed by the pressure roller 10 to remove excess moisture and accelerate curing to obtain a lightweight thermal insulation material that meets the requirements. The adjustable upper roller 1002 can be adjusted according to the material thickness to ensure the squeezing effect.
