Detailed Description
Example 1
The uniform drying device for the lost foam as shown in fig. 1 comprises an inner shell 1 and an outer shell 2, wherein an air guide gap 3 is formed between the inner shell 1 and the outer shell 2; a plurality of through holes 4 are uniformly distributed on the inner shell 1, and the top of the outer shell 2 is hinged with a sealing cover 5; the air guide gap 3 is communicated with an air inlet pipe 6, and the air inlet pipe 6 is sequentially communicated with an air pump 8, a heater 7 and an air-water separator 9; a temperature sensor 11 is arranged in the inner shell 1 and is communicated with an air outlet pipe 13; the air pump 8 is communicated with a U-shaped pipe 15 through an air transmission main pipe 14, two ends of the U-shaped pipe 15 are respectively communicated with air inlet pipes 6 at two ends of the heater 7, and two ends of the U-shaped pipe 15 are respectively provided with an electric regulating valve 16; the electric regulating valve 16 and the temperature sensor 11 are both connected with a PLC (programmable logic controller) 17 in a wired or wireless mode.
The outlet pipe 13 is provided with a check valve 18. The bottom of the inner shell 1 is fixedly connected with the outer shell 2 through a supporting block 19. An annular baffle 20 is fixed on the top of the air guiding gap 3. A handle 21 is fixed to the cover 5.
The utility model discloses a use method as follows:
put into interior casing 1 after brushing fire-resistant paint with the foam model, then air pump 8 starts, the left electricity of U-shaped pipe 15 adjusts the valve 16 and opens, the air passes through heater 7, then get into air guide clearance 3 after filtering out moisture wherein through gas-water separator 9, then through interior casing 1 go up evenly distributed's through-hole 4 dispersion entering interior casing 1 everywhere, thereby make interior everywhere temperature of casing more even, make the disappearance mould of foam model preparation everywhere temperature uniform unanimous, then gaseous flow out from outlet duct 13 again, check valve 18 is used for preventing that the air pump from stopping when ventilating, external moisture gets into interior casing 1 along with the air through the outlet duct. The temperature in the casing in the temperature-sensing ware 11 response to adjust the degree of opening and shutting of the electronic regulating valve 16 on the left side of U-shaped pipe 15 when the temperature is higher than the threshold value and reduce, adjust the electronic regulating valve 16 on the left side of U-shaped pipe 15 when the temperature is less than the threshold value and open and shut the temperature and increase, thereby guarantee that temperature is stable in interior casing 1. When the drying is finished, the electric regulating valve 16 on the left side of the U-shaped pipe 15 is closed, and the electric regulating valve 16 on the side of the U-shaped pipe 15 is opened, so that the external cold air enters the inner shell 1 to rapidly and uniformly cool the lost foam mold manufactured by the foam model after moisture is filtered.
