[0032] Embodiment 2:

[0033] The utility model discloses a melt filter for non-woven fabric production, wherein a vacuum interlayer is arranged inside a filter barrel 1, and an air extraction pipe at the lower end of a vacuum pump 4 is located in the vacuum interlayer, so that the filter barrel 1 can obtain a vacuum layer by cooperating with the vacuum pump 4, thereby achieving the effect of internal heat preservation.

[0034] The utility model provides a melt filter for non-woven fabric production through improvement, and its working principle is as follows;

[0035] First, when using this device, first place the device in the working area, and then connect the device to the external power supply and external controller to provide the required power for the operation of the device;

[0036] Second, the melt is first driven into the filter barrel 1 through the inlet pipe 3, and the melt will accumulate on the top surface of the filter screen 8, and slowly pass through the filter screen 8 due to gravity. Then, the motor 5 is started through the external controller, and the motor 5 drives the rotating column 71 through the output shaft. The rotating column 71 passes through the lower end protrusion and the second electric push rod 75; the lower end telescopic rod drives the connecting piece 72 to rotate, and the connecting piece 72 drives the two sets of stirring plates 74 to rotate and stir, thereby stirring the melt and driving the melt downward, so that the melt is accelerated to pass through the filter screen 8, and the melt reaches the lower end of the filter barrel 1 and the upper end of the piston tube 61;

[0037] Third, the first electric push rod 63 is started by an external controller, and the first electric push rod 63 drives the large piston plate 62 to perform piston movement through the telescopic rod. When the large piston plate 62 moves upward, the large piston plate 62 will cover the first discharge pipe 64. At the same time, because the pressure of the melt above is greater than the pressure of the small piston plate 69 inside the second discharge pipe 65, the melt will push the small piston plate 69 to move outward along the limit column 67 and compress the reset spring 68, so that the melt passes through the second discharge pipe 65 to reach the outside. When the large piston plate 62 moves downward, the reset spring 68 will make the small piston plate 69 close the second discharge pipe 65 again, so that the melt at the upper end of the filter barrel 1 is drawn to the lower end of the filter barrel 1, so that the melt quickly passes through the filter screen 8, and then the melt is driven to the outside through the first discharge pipe 64, thereby completing the filtration of the melt;

[0038] Fourth, when the filter barrel 1 needs to be cleaned, water enters the filter barrel 1 through the inlet pipe 3, and the second electric push rod 75 is started by the external controller. The second electric push rod 75 will drive the lower end of the connecting piece 72 to leave the middle through hole of the filter screen 8 through the telescopic rod. The flowing water will flush the impurities on the top surface of the filter screen 8 to the lower end of the filter barrel 1 through the through hole, and drive the outside through the first discharge pipe 64, thereby completing the cleaning work.

[0039] The utility model provides a melt filter for non-woven fabric production through improvement, by arranging a piston mechanism 6 at the bottom of the filter barrel 1, when the melt reaches the inside of the filter barrel 1, the large piston plate 62 performs piston movement under the drive of the first electric push rod 63, so that the melt is pumped to the lower end of the inside of the filter barrel 1, allowing the melt to quickly pass through the filtration of the filter screen 8, and reach the outside through the cooperation of the first discharge pipe 64 and the second discharge pipe 65; by arranging a stirring mechanism 7 at the lower end of the output shaft of the motor 5, when the stirring mechanism 7 rotates under the drive of the motor 5, the shape of the stirring plate 74 causes the melt to be pressed downward under the drive of the stirring plate 74, thereby increasing the melt filtration efficiency and reducing the probability of impurities clogging the filter screen 8. During cleaning, the second electric push rod 75 drives the lower end of the connecting member 72 to leave the through hole of the filter screen 8, so that impurities can flow to the outside through the through hole of the filter screen 8.
