Drying equipment for metal product machining

[0034] Example 1, such as Figure 1-2 As shown, when the temperature in the body 1 is perceived by the temperature monitoring system 52, when the specified index is perceived, the negative pressure fan 53 can be taken automatically in the communication of the conduit 54, and forced the negative pressure fan 53. The feed port 4 is introduced into the feed port 4 by the guide flow of the circulation conduit 51, so that the metal article falling into the feed port 4 is preheated, which not only improves the subsequent heating and drying efficiency of the metal article, but also in part of the gas reflow body 1, Another part of the gas is directly in contact with external air, increasing the flexibility and convenience of the temperature control.

[0035] Example 2, such as Figure 2-4 As shown, when the metal article rolls into the inner side wall of the tapered groove 35, the inside and outside sidewalls of the tapered groove 35 can be heated in advance by the activation of the electric heating tube 363, and the electric heating tube 363 is promoted by the formation of the fan 362. The formed hot gas is more rapidly drawn upward. At this time, not only improve the water stains of the inner side wall of the tapered groove 35 contact the metal article, and the heat gland 31 and the heating gas of the electric heating tube 363 are mixed with each other, and flow in the device It is facilitated that the metal article has a wider contact surface under the flow of hot gas, and the drying efficiency is better.

[0036] Working Principle: When the device is used, first control the hot air set 31 and the electric heating tube 363 as the heating system by the controller 2, and then introduced from the feed port 4 from the feed port 4, d
