Radial radiation-type rotational filter screen disc and preparation method thereof

Abstract

The invention provides a radial radiation-type rotational filter screen disc and a preparation method thereof. The radial radiation-type rotational filter screen disc comprises an internal rim and an external rim; a radial radiation-type filter screen which is uniformly distributed along the circumference and formed by winding a filter screen wire is arranged between the internal rim and the external rim; two axes center pressing covers are fixedly buckled to the positive surface and the reverse surface of the internal rim; and the center of the axes center pressing cover is provided with a shaft sleeve matched with the output shaft of a motor. The preparation method comprises the following steps of: firstly fixing the front end of the filter screen wire on the internal rim and leading thefront end to attach to the positive surface of the internal rim closely and enwind at the corresponding radial points of the external rim; subsequently leading the front end to closely attach to thereverse surface of the external rim, return in original route and enwind at the adjacent points of the internal rim; rotating the external rim by an angle; subsequently leading the filter screen wireto attach to the positive surface of the internal rim and enwind at another radial corresponding point of the external rim; repeatedly carrying out the above operations till all filter screen wires are uniformly weaved by one ring; and subsequently fixing the tail end of the filter screen wire on the external rim and finally using the two axes center pressing covers to clamp the internal rim fromthe positive surface and the reverse surface. The method has the advantages of good running stability and balance performance, high efficiency of intercepting dust and granules and long service life.

Description

technical field [0001] The invention relates to a core filter component in a centrifugal purification device for controlling air dust particle pollution, in particular to a radial radiation type rotary filter disc and a manufacturing method thereof. Background technique [0002] In the process of controlling atmospheric environmental pollution, the capture of fine dust particles and floating objects has always been a major problem that has plagued researchers for a long time. The generation of fine dust particles in the atmosphere mainly comes from the following forms: one is from the cooking fume from home kitchens and restaurants and hotels. These volatile particles with high viscosity cause long-lasting pollution to the atmosphere; the other is the source The waste gas discharged from various manufacturing plants, processing plants and chemical plants contains a large amount of dust particles and harmful substances, which are directly discharged into the air without treat...

Problems solved by technology

But it still has the following defects: First, it is not easy to match the air velocity, pressure loss, power consumption and dust removal efficiency of the centrifugal dust collector. Although the excessive air velocity can improve the dust removal efficiency, it will inevitably cause pressure loss and power consumption Too large, resulting in a substantial increase in operating costs, so the airflow velocity at the inlet can only be limited to 8-18m / s, and the efficiency of the equipment is only about 70% when it is working normally

In this way, when the filter disc rotates at high speed, there will still be a slight eccentricity and unbalance, and the cross-overlapped weaving is also prone to accumulation and blockage of fine dust particles, resulting in increased wind resistance, increased noise, and reduced interception efficiency of the filter disc.
