Abstract
The invention discloses an air-lar machine negative pressure sucking-off plant, which comprises an exhaust inlet, an air intake duct, an induced-draught fan and an exhaust pipe, wherein the exhaust inlet is connected to the bottom end of an output curtain and is also connected with the air intake duct; the bottom end of the air intake duct is connected with the induced-draught fan; and the side of the induced-draught fan is connected with the exhaust pipe. The air-lar machine negative pressure sucking-off plant of the invention generates downward artificial flowing air flow between the output curtain and a hot milling, thereby offsetting the upward air flow generated by the hot milling at high temperature, and enabling a fibre web to enter the hot milling steadily. The plant is simple and practical, and the exhaust pipe is a PPR plastic tube with the diameter of 150mm; the connection part of the exhaust pipe is connected by a PPR interface and a bend tube, thereby being convenient to assembly and disassembly; and a filter is arranged on the air inlet of the induced-draught fan to filter the remained cotton on filter condense cotton so as to prevent the plug of the induced-draught fan.
Description
Technical field
The present invention relates to a kind of air-lar machine negative pressure sucking-off plant.
Background technology
Before the prior art random web-laying equipment does not add negative suction system, when random web-laying equipment output fiber web enters the hot-rolling mill hot rolling through the transmission of output curtain, hot-rolling mill roller surface temperature is the condition of high temperature, between output curtain and hot-rolling mill, produce very big thermal current, be subjected to the fiber web on the effect output curtain of this thermal current can produce floating, the pleating phenomenon of fibre web in the hot-rolling mill porch, can produce broken hole when serious, have a strong impact on product quality, can't continuous and stable production.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can between output curtain and hot-rolling mill, produce downward artificial air flow, thereby offset the updraft that hot-rolling mill high temperature produces, make fiber web steadily enter the air-lar machine negative pressure sucking-off plant of hot-rolling mill.
The technical scheme that the present invention is adopted for achieving the above object is: air-lar machine negative pressure sucking-off plant, comprise the inlet scoop that is connected output curtain bottom, be connected with air intake duct on the inlet scoop, the air intake duct bottom is connected with induced-draught fan, and the induced-draught fan side is connected with blast pipe.
The air inlet place of described induced-draught fan is equipped with filter.
On described air intake duct and the blast pipe connecting flange is installed.
Described output curtain is connected on the random web-laying equipment.
Air-lar machine negative pressure sucking-off plant of the present invention, by negative suction system is set, between output curtain and hot-rolling mill, produce downward artificial air flow, thereby offset the updraft that hot-rolling mill high temperature produces, make fiber web steadily enter hot-rolling mill, this device is simple and practical, blast pipe adopts the PPR of diameter 150mm to mould pipe, the blast pipe junction adopts the PPR joint to be connected with bend pipe, can make installation, convenient disassembly, at induced-draught fan air inlet place filter is installed, is filtered the surplus cotton on the fibre-condensing, in order to avoid stop up induced-draught fan.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is an air-lar machine negative pressure sucking-off plant structural representation of the present invention;
Fig. 2 is an air-lar machine negative pressure sucking-off plant A of the present invention place partial enlarged drawing.
Among the figure: 1, random web-laying equipment; 2, output curtain; 3, inlet scoop; 4, filter; 5, induced-draught fan; 6, connecting flange; 7, blast pipe.
The specific embodiment
As shown in Figure 1, air-lar machine negative pressure sucking-off plant comprises random web-laying equipment 1, output curtain 2, inlet scoop 3, filter 4, induced-draught fan 5, connecting flange 6, blast pipe 7 and air intake duct 8, the inlet scoop 3 of this negative suction system is connected the bottom of output curtain 2, air intake duct 8 is connected on the inlet scoop 3, air intake duct 8 bottoms are connected with induced-draught fan 5, the side of induced-draught fan 5 is connected with blast pipe 7, on this air intake duct 8 connecting flange 6 is installed, the air inlet place of induced-draught fan 5 is equipped with filter 4, be used to filter the surplus cotton on the fibre-condensing, avoid stopping up induced-draught fan, connecting flange 6 is installed on the blast pipe 7, wherein export curtain 2 and be connected on the random web-laying equipment 1.During this negative suction system work, start induced-draught fan 5, hot-rolling mill elevated temperature heat air-flow 3 is inhaled into from the inlet scoop, enter air intake duct 8, through filter 4 with surplus cotton filtration the on the fibre-condensing after, the high temperature hot gas blast pipe 7 of flowing through is discharged the use of this negative suction system, the elevated temperature heat air-flow that hot-rolling mill is produced is in time eliminated by this device, thereby has guaranteed that the fiber web on the output curtain enters hot-rolling mill reposefully.
