Dewatering device for spunlace production line

Abstract

The invention discloses a dewatering device for a spunlace production line. The device comprises a rack which is composed of a rack front support, a rack rear support, a rack upper supporting beam and a rack lower supporting beam, a left negative-pressure water suction box, a right negative-pressure water suction box, a hot air diffusion box, a supporting net curtain driving roller, a supporting net curtain driven roller, a supporting net curtain deviation rectifying roller, a supporting net curtain driving roller driving mechanism and a supporting net curtain. The front end of the left negative-pressure water suction box is fixed with the rack front support, the rear end of the left negative-pressure water suction box is closed, and the upper part of the left negative-pressure water suction box is provided with a left negative-pressure water suction box water suction port; the front end of the right negative-pressure water suction box is fixed with the rack front support, the rear end of the right negative-pressure water suction box is closed, and the upper part of the right negative-pressure water suction box is provided with a right negative-pressure water suction box water suction port; the lower portion of the front end of the hot air diffusion box is borne on the front end of the right negative-pressure water suction box, the rear end is fixed with the rack rear support, a mesh plate is arranged in a cavity of the hot air diffusion box, and a hot air uniform diffusion filter screen pad is arranged on the mesh plate; the supporting net curtain driving roller is arranged on the upper portions of the rack front support and the rack rear support, the supporting net curtain driven roller is arranged between the upper portions of the rack front support and the rack rear support, and the supporting net curtain deviation rectifying roller is arranged between the lower portions of the rack front support and the rack rear support; the supporting net curtain driving roller driving mechanism is arranged at the front side of the rack front support; and the supporting net curtain sleeves supporting net curtain driving roller, the supporting net curtain driven roller and the supporting net curtain deviation rectifying roller. The good dewatering requirement on a spunlace non-woven product with large gram weight is met.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a dewatering device for a spunlace production line. Background technique [0002] As known in the industry, the spunlace non-woven production line, that is, the spunlace production line, is usually equipped with a dehydration device, and the dehydration method generally adopts a vacuum or negative pressure method. The non-woven products from the spunlace machine, such as spunlace non-woven fabric or felt It is dehydrated by the dehydration device, and then enters the drying process for drying (also called "drying"). [0003] The technical information related to the dehydration device used in the spunlace production line can be seen in the published Chinese patent documents, typically such as the "water extraction device" recommended by the authorized announcement number CN107208343B. This patent has the effect of recovering waste heat, but has the followin...

[0003] The technical information related to the dehydration device used in the spunlace production line can be seen in the published Chinese patent documents, typically such as the "water extraction device" recommended by the authorized announcement number CN107208343B. This patent has the effect of recovering waste heat, but has the following shortcomings: First, since the focus is on the internal mechanism of the hot air diffusion box, no technology is given to enable the spunlace non-woven fabric (the patent is called "non-woven fabric") to pass through the negative pressure suction box smoothly with the assistance of the conveyor belt Enlightenment; secondly, it can be determined from the accompanying drawings of the patent specification and the content of the specification that the aforementioned negative pressure suction box is in the form of a single box configuration, so the dehydration effect of non-woven fabrics with a large grammage will be affected to a certain extent. Of course, there will be no Slowing down the moving speed of the spun fabric can improve the dehyd
