Description

The invention relates to the construction, mainly to the industry of heat insulating materials, and can be used to provide resource-saving technology for the manufacture of pierced mats made of fiberglass panels, used in various industries of the national economy.

The goal / acquisition is to increase production, automate the entire production line, prevent

isolation and distribution of fine toxic dust.

The drawing shows a production line for making piercing mats of glass fiber waste, a general view.

The technological line contains a drying chamber 1 with a conveyor 2, a charging port 3 and a warm air duct 4 from the electrocalorifer, a waste cutting machine 6, a moving grid 7 with dust sucking air 8, directing rollers 9, a needle drum 10 with an electric motor 11 and fan 12, hopper 13 g. ejector 14 and supercharger 15, rolled fiberglass 16 and 17c moving tensioning and camshafts 18 and 19, thermal heaters 20, filling table 21 and mat formats with pressure umbrella 22 and sucking in an air guide 23, a feed mechanism 24 for flashing, a piercing machine 25 with a needle thread 26, a cutting machine 27 and a conveyor 28 with a system 29 moving to a warehouse of 30 finished products.

Technological line works as follows.

Fiberglass wastes 5, which are 10-400 mm long glass fiber scraps, enter the drying chamber 1 through the charging port 3, in which the waste is captured by the conveyor 2 and slowly raised up with the help of needle bars, where they are dried during movement and dumped onto the machine 6 for shredding waste pieces of 40-100 mm in length, since long length fibrous waste pieces are difficult to fluff because of their high strength. In the process of slow movement of fiberglass wastes on conveyor 2, they are dried with warm air from an electric air heater with high-temperature electrodes entering through duct 4. To save heat, air is drawn into the electric air heater from drying chamber 1. After cutting on a disk machine, 6 pieces of soft fiber waste will be removed on the movable grill 7, where they are distributed across the entire width and are gripped by guide presser rollers 9, rotating towards each other, feeding glass yarn to the needle the drum 10 rotating at a speed of at least 1000 revolutions / mime by means of a V-belt transmission or electric motor 11 connected by means of a reducer to the moving grid 7 and the fan 12. A umbrella with a suction duct 8 is installed above the moving grid 7, preventing the distribution of fine dust on the room. At the exit of the needle drum 10, the fluffed fiberglass wastes are picked up by the air flow from the fan 12 and fed to the storage hopper 13 through an air duct connecting the housing of the fluffing machine to the filling hopper 13, from which the ejector 14 is sucked in and through the supercharger 15 filling the shell which is formed from a rolled fiberglass cloth wound on the top 16 and bottom 17 drums, of which the tension camshafts 18 and 19 are fed to thermo-electro firmware through

5 both sides with aggregates 20 by sintering glass fiber cloth from upper and lower rolls

The glass mat is formed on a table 21 above which

0 a pressure pad with a grill 22, which prevents the shell from inflating when filled with glass mass, and the injected air is sucked out by the air duct 23.

5 The formed mat is captured.

the feed mechanism 24 to the firmware, and then enters the thermo-electric stitching machine 25 with thermoelectric heating needles 26, the frequency of the stitched lines in

0 squared is in the order of 100x100 mm.

Strong rings are formed around the thermoelectric heating needles by sintering glass fibers, fixing the glass fibers in the glass cloth sheath.

5 The cross-cutting of the stitched mats of a given length is carried out by the machine 27. After which it enters the conveyor 28, driven by an electric motor 29, through which the finished products are transferred to the finished product warehouse.

Purification of the exhausted ventilation air from the air ducts 8 and 23 is carried out in special bag filters of the type FER, due to which it is achieved

5 required degree of cleaning and protection of the environment from emissions of fine, toxic dust.

The use of the technological line according to the invention has found application in waste with a low coefficient of thermal conductivity, which was previously dumped in dumps, contaminating the environment. Productivity at the same time increased three times and almost completely eliminated

5 the isolation and distribution of toxic dust in the workshop room due to an organized intake and suction ventilation system. Also, the use of a production line made it possible to automate all operations of the technological process.,

freeing the hard work of seven workers. Glass fiber waste mats have high elasticity. transportability during transportation, as well as the possibility of their reuse.
