The invention is further described with reference to the following figures and detailed description. As shown in fig. 1-2, the water electret meltblown fabric drying system of the present invention includes an oven 2 for drying a meltblown fabric 3 after water electret, and a winder 4 for winding and collecting the dried meltblown fabric 3, wherein the oven 2 is provided with an inlet and an outlet through which the meltblown fabric 3 passes, the drying system further includes a first exhaust fan 5 for pumping hot gas from the meltblown 1 to the oven 2, an air inlet of the first exhaust fan 5 is connected to the meltblown 1 through a vent pipe, and an air outlet of the first exhaust fan 5 is connected to the oven 2 through a vent pipe.
In this embodiment, the air inlet of the first exhaust fan 5 is connected to the web former 11 in the melt-blowing machine 1 through an air pipe. As the superfine fibers sprayed by the melt-blowing die of the melt-blowing machine 1 are bonded to form melt-blown cloth in the web forming machine 11, a large amount of heat energy needs to be pumped in the forming process, and the air inlet of the first exhaust fan 5 is connected with the web forming machine 11, so that the heat energy to be discharged can be better collected.
In the above technical solution, a plurality of horizontally disposed air suction pipes 21 are disposed in the oven 2, and the cross section of the air suction pipe 21 may be square as shown in fig. 1, circular as shown in fig. 2, or other polygonal shapes. Wherein, the upper part of the air suction pipe 21 is provided with a notch 211, the melt-blown fabric 3 is positioned above the notch 211 of the air suction pipe 21 when passing through the oven 2, and the air suction pipe 21 is connected with the air inlet of the second exhaust fan 6.
When the meltblown fabric 3 passes through the oven 2, the second exhaust fan 6 is opened, hot air in the oven 2 penetrates through the meltblown fabric 3 and enters the air suction pipe 21, and then the meltblown fabric is drawn out of the oven 2 by the second exhaust fan 6. Compared with the prior art that hot air flows on the surface of the melt-blown fabric for evaporation drying, the invention has the advantages that high-speed convection is realized by the air flow in the oven 2 under the action of the second exhaust fan 6, moisture is taken away by penetrating the melt-blown fabric 3 through hot air, and water on the melt-blown fabric 3 is rubbed with fibers to generate static electricity in the process of penetrating the melt-blown fabric 3 along with the hot air, so that the adsorption effect of the melt-blown fabric 3 is further improved, the drying efficiency is higher, and the heat energy is more thoroughly utilized.
In the above technical scheme, the air suction pipes 21 are distributed in an upper layer and a lower layer, and a roller group for adjusting the moving direction of the melt-blown fabric 3 is arranged between the two layers of air suction pipes. The roller set in this embodiment includes a first roller 71, a second roller 72 and a third roller 73, the first roller 71 is located at one end of the upper layer air suction pipe away from the outlet of the oven 2, the second roller 72 is located above one end of the lower layer air suction pipe away from the inlet of the oven 2, the third roller 73 is located right below the first roller 71, and the third roller 73 is located above the second roller 72 in vertical height. The melt-blown fabric 3 enters from the inlet of the oven 2 and is dried above the cut of the lower-layer air suction pipe, and then is dried above the cut of the upper-layer air suction pipe after the moving direction is adjusted by the second roller 72, the third roller 73 and the first roller 71 in sequence. The double-layer drying further improves the drying efficiency.
In practical applications, the roller sets are not limited to the distribution of the embodiment, and other distribution modes that can adjust the moving direction of the meltblown fabric 3 and move the meltblown fabric 3 over the notches of the upper and lower suction ducts can be adopted. For example, as shown in fig. 1, the inlet of the oven 2 and the third roller 73 move downward, the meltblown fabric 3 enters the oven 2 and then passes through the lower portion of the lower layer air suction pipe, then passes through the upper portion of the lower layer air suction pipe after rotating around the fourth roller 76, and then passes through the upper portion of the upper layer air suction pipe after adjusting the moving direction by the third roller 73 and the first roller 71.
In the above technical solution, the inlet of the oven 2 is provided with an inlet roller 74, and the outlet of the oven 2 is provided with an outlet roller 75.

The structure of the air outlet nozzle 22 is similar to that of a shower outlet nozzle in life, and the air outlet nozzle is arranged right above the cut of the air suction pipe 21, so that hot air pumped from the melt-blowing machine 1 penetrates through the melt-blowing cloth 3 immediately, and the heat energy utilization rate is further improved.
In the above technical scheme, the outlet of the oven 2 is further provided with a humidity sensor 23 for controlling the rotation speed of the second exhaust fan 6. And when the humidity sensor 23 detects that the humidity of the melt-blown fabric at the outlet of the oven 2 is unqualified, the rotating speed of the second exhaust fan 6 is automatically adjusted.
In addition, the melt-blowing machine 1 is integrally connected with the water electret equipment, superfine fibers sprayed by a melt-blowing die of the melt-blowing machine 1 after the integral connection directly enter the water electret equipment after the web former 11 is bonded to form melt-blown cloth 3, a winding machine and an unreeling machine 91 between the melt-blowing machine 1 and the water electret equipment are omitted, the occupied area is reduced, meanwhile, the melt-blown cloth from the melt-blowing machine 1 is directly subjected to water injection treatment, compared with the prior art that one set of water injection equipment is independently adopted, the winding and unreeling actions of the melt-blown cloth 3 after the forming are reduced, and the automation degree and the production efficiency are improved.
