Description of the drawings:

1. system architecture

As shown in fig. 1, a first rotating rod 1-1, a second rotating rod 1-2 and a motor 2 are used for realizing the continuous rotation of a mesh belt 3, the air flow is formed by the negative pressure of an air inlet system of the original equipment, and the flying cotton in the air is intercepted at a wire mesh of an air inlet and attached to a filter screen at the inlet side; when the filter screen rotates to reach the inside of the shell of the cleaning device, the flying cotton fibers are peeled and removed; the silk screen that the clearance is clean rotates to the device air-out side, and clean air gets into former equipment air inlet unit, reduces to fly to wadding and adheres to. The collected flying flocs are collected and discharged through the water film adsorption effect to form a self-circulating water system.

2. System self-circulation air system

As shown in fig. 2, in the cleaning device, the fly-wadding gathered by the wire mesh is blown out by the air of the positive pressure air chamber to reach the fly-wadding collecting plate 9-1 at a certain wind speed; the flying cotton collecting plate 9-1 is a light plate with an inclination of 1-5 degrees, overflow water of the cleaning water tank flows along the flying cotton collecting plate 9-1 from top to bottom, and the flying cotton is combined with water and is brought into the flying cotton containing collecting chamber to finish the collection and removal of the flying cotton.

And the silk screen which is cleaned by blowing is rotated and recycled after the clean air is pumped out of the chamber to further remove moisture. The self-circulation fan obtains air without flying floc in a clean air pumping chamber in the cleaning device, and the air is boosted and then used in the positive-pressure air chamber to form self-circulation air, so that the air in the wire mesh loop is clean and free of secondary pollution; air leaking or lost from the system is replenished by a barrier with a sealing brush that cleans the air extraction chamber.

3. System self-circulation water system

As shown in figure 3, the water in the flying cotton water collecting chamber of the cleaning device is discharged into the cleaning water tank after being boosted by the self-circulation water pump, the waste water containing the flying cotton forms clean circulating water after passing through a back flush filter screen in the cleaning water tank, the circulating water overflows to the upper part of a flying cotton collecting plate 9-1 with micro-positive pressure after filling the cleaning tank, the water flows downwards and is combined with the flying cotton brought out by air through the flying cotton collecting plate 9-1, and the water flows to the flying cotton water collecting chamber automatically to form complete self-circulation washing.

In the self-circulation flushing process of the system, due to the gathering of flying flocs, a backwashing filter screen is blocked, corresponding differential pressure alarm and forced backwashing control are designed at the position, and when the differential pressure reaches 60 kPa-100 kPa, a backwashing sewage discharge valve and a pipeline are opened to discharge sewage, so that the automatic cleaning of the system is realized. After the sewage is discharged, the discharged lost water is supplemented to the floc water collecting chamber through a pipeline.

4. Equipment installation and arrangement

As shown in fig. 6, the apparatus employs customizable, adjustable supports to control the length of the web and the length of the rotating portion of the apparatus, since the dimensions of the inlet chambers of the apparatus vary widely from apparatus to apparatus, and the width A, D of the apparatus of the present invention will vary from apparatus to apparatus. In order to ensure that the equipment runs reliably, the width of the filtering screen is not too large, and the filtering screen can be curled and deformed during running due to the too large screen width, therefore, the single-layer filtering module is arranged by using the screen with the width of 1 m-1.5 m, the corresponding equipment can be fully covered in the height direction through the expansion module, and when a plurality of pieces of equipment are required to be longitudinally connected and run, the equipment can be lapped through the connecting piece.

The modules are rigidly connected by adopting a rotating part, and the shell of the flushing device adopts a connection mode of splicing and fixing the shell; due to the difference of the served equipment, the upward connection of the modules can adopt the arrangement of a pump and a fan at each stage, and the power of the lowest group can be flexibly used.
