Example Embodiment
[0021] Embodiment 1
[0022] See figure 1 , The device for manufacturing flat plate type special inorganic insulation felt, including nozzle 1, filter 2, shell 7, pressure vessel 4 and vacuum device 5. The pressure vessel 4 is provided with a pressure display device 6. In this embodiment, the pressure display device 6 is a pressure sensor for detecting the pressure in the pressure vessel. The shell 7 is spherical and consists of a hemispherical upper shell and a lower shell. A filter screen 2 is sandwiched between the upper and lower shells. The upper shell communicates with the atmosphere. The cavity formed by the lower shell and the filter screen 2 passes through the pipe It is connected with the vacuuming device 5, the spray head 1 is arranged in the upper shell, and the spray head 1 communicates with the pressure vessel 4 through a pipe. Both the housing 7 and the nozzle 1 are fixed. The nozzle 1 can be single or multiple.

[0026] Embodiment 2
[0027] See figure 2 , The device for manufacturing hat-shaped special inorganic insulation felt, including nozzle 21, filter 22, shell 27, pressure vessel 24, motor 28 and vacuum device 25. The pressure vessel 24 is provided with a pressure display device 26 for detecting the pressure in the pressure vessel. The filter screen 22 is arranged in the housing 27 with a distance between the bottom and the housing 27. The housing 27 communicates with the atmosphere. The filter screen 22 is in the shape of a hat, and is provided with a bottom plate that closes the bottom opening. The bottom plate is fixedly connected with the output shaft of the motor 28, and the motor 28 drives the filter screen 22 to rotate. The filter screen and the bottom plate form a vacuum suction cavity, which is communicated with the vacuum suction device 25 through a rotary joint and a pipe. There are a plurality of spray heads 21, which are evenly spaced along the curved line of the s...

[0030] Embodiment 3
[0031] The device for manufacturing flat type special inorganic thermal insulation felt includes nozzle 31, filter screen 32, shell 37, guide rail 36, beam 34 and vacuum device 35.
[0032] The housing 37 has a cone shape with an open upper part. The filter screen 32 is arranged at the upper part of the inner cavity of the housing. The filter screen 32 and the lower part of the inner cavity of the housing 37 form a vacuum suction cavity, which passes through a pipe and a vacuum device 35 Connected. Two sides of the housing 37 are provided with guide rails 36, the spray head 31 is provided on the cross beam 34, and the bottom of the cross beam 34 is provided with a motor and a roller. The motor drives the roller to rotate, and the roller drives the cross beam 34 to move linearly along the guide rail 36. The spray head 32 communicates with the pressure vessel through a rotary joint and a pipeline. The number of spray heads 31 may be single or multiple, and is ...
