Exploring the disadvantages of blowers
The process of the blower is simple, and the process is: the pearl sand is dried in a special storage tank through a heating furnace for 24 hours, and the hot gas temperature is controlled between 150200e. However, this process has been used in our factory for several years and has the following shortcomings: (1) Since the interlayer is not dried, even if the pearl sand is dry and dry, it will inhale a lot of humid air after entering the interlayer. (2) After the pearl sand enters the interlayer, it is compacted by the vibration of the vibrating table and the vacuum pressure difference generated during the sand suction, and the compaction degree cannot meet the requirements in actual use. After the sand-filled cryogenic tank is used for less than 3 months at the factory, the laminated pearl sand has been severely exposed at the top of the interlayer. 1) Double-machine Shandong vacuum pump 2) Water ring pump 3) Tank sandwich (vacuum powder) 4) Molecular sieve adsorber 5) Oil-free air compressor 6) Electric furnace 7) Piping system 8) Pearl sand tank for the process of Figure 4 Insufficient, the author redesigned the process of drying pearl sand and sucking sand into the interlayer, the process is: (1) Combine the compressor and the heating furnace to heat the Shandong sand sieve machine, heat the dry air adsorbed by the molecular sieve to 300e, and then pass through the pearl sand storage tank to dry the pearl sand. (2) When the exhaust gas of the dried pearl sand reaches 50e, it is passed into the interlayer to be filled with pearl sand and dried. After the pearl sand and the interlayer are dried, the vacuum pump is started to vacuum and absorb the interlayer into the interlayer. (3) When the pearlite sand of the interlayer is about to be filled, the vacuum state of the interlayer and the pressure difference of the hot air at the top of the pearl sand storage tank are simultaneously sucked, and the intercalated pearl sand is intermittently compacted. In actual use, there are improvements in the following aspects: due to the high air temperature generated by the combination of the compressor and the electric furnace, and the gas volume is also large, the drying time of the pearl sand can be greatly reduced; the interlayer and the pearl sand are heated and dried together. Dry, so it reduces the amount of humid air adsorbed by the pearl sand into the interlayer; there is a pressure difference of 012013MPa between the pearl sand tank and the interlayer, which can compact the pearlite of the interlayer to the ideal state, and it is proved by actual use that the sand is filled with this process. The vacuum powder tanker does not need to be sanded within one year, which shows that the quality of sand loading has been improved.
