Description
Technical Field
The invention belongs to the technical field of non-woven machinery, and particularly relates to a dewatering device for a spunlace production line.
Background
As is known in the art, a dewatering device is usually installed in a spunlace nonwoven production line, and the dewatering method generally adopts a vacuum or negative pressure method, and a nonwoven product from a spunlace machine, such as a spunlace nonwoven fabric or a felt, is dewatered by the dewatering device and then dried (also called "drying") in a drying process.
Technical information relating to dewatering devices for hydroentangling lines, typically "water extraction devices" as recommended in the publication No. CN107208343B, is found in the published chinese patent literature, which has the effect of recovering waste heat, but has the following disadvantages: first, because the focus of the side is the internal mechanism of the hot air diffusion box, no technical suggestion is given that the spunlace nonwoven fabric (called as "nonwoven fabric") can smoothly pass through the negative pressure water suction box with the help of the conveyer belt; secondly, it can be confirmed from the drawings and the content of the specification of the patent that the negative pressure suction box is in a single box configuration form, so that the dewatering effect on the nonwoven fabric with large gram weight is influenced to a certain extent, and naturally, the travelling speed of the nonwoven fabric is properly slowed down, so that the dewatering effect can be improved to a certain extent, but the productivity in unit time, namely the hydro-entangled working efficiency is influenced; thirdly, the negative pressure of the negative pressure suction box in the operation process cannot be prompted and cannot be adjusted on line according to needs, so that inconvenience and even blindness can be caused in the actual production process; fourthly, because the patent does not give the respective positions of components such as a frame, a negative pressure suction box, a cloth guide roller, a net supporting curtain and the like and the reasonable matching relationship among the components, the complete dewatering device has certain confusion; fifth, it can be known from the summary of the patent specification that the structure of the whole hot air diffusion box is relatively complex and the recycled hot air needs to be led out to the negative pressure suction box through the metal plate element, the fine metal mesh and the perforated metal plate element in sequence, so that the power of the vacuum pump must be correspondingly increased due to the large resistance of the hot air, which is not beneficial to saving energy. In view of the foregoing, and not by way of limitation, there is a continuing need to explore and reasonably improve upon the background that will be described.
