Description

(54) DEVICE FOR COLLATING AND DEPOSITING VOLATILE PARTICLES OF FIBER AND DUST

one

The invention relates to the knitwear, apparel and textile industry and can be used under transport conditions to remove waste.

Famous frame filters are used to trap and precipitate volatile fiber particles. They represent the frame on which the tension of the filter sheet 1.

A disadvantage of such filters is the need to periodically stop the system to manually clean the filter surface in dusty dust suction rooms.

A device for trapping and precipitating volatile particles of fiber and dust, containing a filtering surface passing through the entire cross section of the exhaust channel and passing only air, a purge element with outlet openings directed to the filtering surface, separate air elements in front of separate sections of the filtering surface, a shut-off gate located between

located below the collector and the suction channel 2.

The main drawback of the device is the complexity of the design, which is expressed in the fact that for cleaning the filtering surface, there is a special system with blowing elements, each of which stands against its own section.

Thus, the device includes

a lot of locking devices and system

to control them, this creates a cumbersome structure and reduces its reliability.

The purpose of the invention is to provide long-term functional capabilities of the device, reducing maintenance costs.

 This goal is achieved by the fact that each frame is provided with lattices connected with its lower ends by means of a spring, while the locking device is made in the form of a shutoff device installed in

2Q pipeline.

FIG. I shows a section of one of the sections of the grille with a frame; in fig. 2 — a device for trapping and precipitating volatile particles of fiber and dust. The device contains a frame 1, a lattice 2, a filtering surface (canvas) 3. In the lower part, the lattice 2 is connected to frame 1 by hinges 4. The rods 6 are attached to the upper part of the lattice by means of hinges 5 6. Push rods are fixed through holes on the frame 1. Springs 8 worn on rods 6. Washers with nuts 9 limit the action of the springs 8. Section 11 is installed in the collection chamber of waste 10. In pipe 12 connecting the chamber 10 to the fan 13, there is a cutter 14, with a handle 15 The device works as follows: Induced valve 13 Oromo air bearing, for example, manufacturing process waste of sewing a flap of various sizes, as well as fine fibers and dust prosasyvaets chamber 10 through waste collection. Waste is deposited in the chamber, and fine fibers and dust are trapped on the filter surface of the device sections 11. The purified air, the passage through conduit 12, is emitted into the atmosphere. As the filter fabric of 3 sections of the device clogs with fine fibers, the resistance of the latter to the passage of air increases. When the resistance of the filtering web reaches a value exceeding the elastic force of the springs 8, under the influence of the air flow, the grating 2 of the section is closed by the filtering web 3 and connected by hinge 4 to the frame 1, deviates in the direction of the air flow. In this case, the spring 8 sozhmuts. In order to shake the filter surfaces of the sections, the shut-off device 14 is turned sharply. The pipeline 12 closes and the air flow rate drops to zero at this time. The lattice 2 of the sections of the device under the influence of the springs 8 abruptly returns to its original position, in which the filter surface is in a tensioned state. As a result of the impact that occurs, the layer of volatile fibers and dust on the filtering surface is scattered. Thus, when using the proposed device, the positive effect is simplicity of design and reliability, since a large number of locking apparatus is absent in the device as compared with the known, which considerably reduces the cost of its manufacture and use. Apparatus of the Invention A device for trapping and precipitating volatile particles of fiber and dust, containing sections with frames and a filtering element, pipelines and shut-off devices, characterized in that, in order to ensure long-term functional ability of the device, to reduce the labor costs for maintenance, each frame is equipped with gratings connected with its lower ends by means of hinges, and the upper ends by means of a spring, while the locking device is designed as a shutoff device installed in the pipeline.
