Abstract

The utility model provides a foam aluminum filtering device for reducing noises. The foam aluminum filtering device comprises stainless steel filtering silk screens, foam aluminum and covers, wherein the whole device is fixedly arranged in a water system pipeline; and circular U-shaped grooves and straight-line grooves of the corresponding upper and lower covers are internally, respectively and fixedly provided with an I-grade stainless steel filtering silk screen, an II-grade stainless steel filtering silk screen and an III-grade foam aluminum filtering sheet in sequence to form a foam aluminum filtering screen. Compared with the prior art, the foam aluminum filtering device has the advantages that the defects that a filter only can filter and purify and cannot absorb the noises are made up; the device has a small size and can be circularly applied; grains and short fibers with the grain diameters and the lengths of being more than 0.9 millimeters can be filtered and purified; and running water containing the short fibers and grain-shaped suspension matters in military and civil water treatment processes can be subjected to integration of screening, filtering, purification and noise absorption.

Description

A kind of noise reduction foamed aluminium filter

Technical field

A kind of noise reduction of the utility model foamed aluminium filter, the technical field of relate to the water treatment screening, filtering and absorbing sound, specially refer to the technical field of screening, filtration and the sound absorption of dual-use upper design water treatment, be used for the need water treatment screening of outlet pipe, the water outlet of filtering and absorbing sound.

Background technology

Along with further developing of environmental pollution prevention and control and improvement, requirement to water treatment is also more and more higher, adopt at present various wire gauzes and polyurethane etc. a lot of as the filter of filtering material, but these filters only relate to screening, filtration and the purification of water, in water treatment, do not take into account the modern designs of sound-absorbing, can not be in water treatment, turbulent underwater sound in the water pipe etc. is absorbed sound, can't build a quiet environment.

Summary of the invention

The purpose of this utility model is to overcome defects, remedying filter can only screen, filters and purify, and the shortcoming that can not absorb sound and defective, design a kind of sound absorbing capabilities advantage of foamed aluminium in water of both having utilized, utilize again the characteristics of the micropore through hole of foamed aluminium, on the basis that guarantees discharge, water is screened, filters, purifies and absorbs sound, thereby reach a kind of noise reduction foamed aluminium filter that filter not only filters but also can absorb sound.Its technology is achieved in that and comprises that stainless steel filters silk screen, foamed aluminium board, housing, threeway, silently, it is characterized in that: whole device is fixed in the water system pipeline, in the circular U-lag of corresponding upper and lower two housings and the straight-line groove in order, fixedly I grade stainless steel screening silk screen, II grade stainless steel filter silk screen respectively, III level foamed aluminium filter forms the foamed aluminium screen pack, described III level foamed aluminium filter major bore is at 0.9-0.7mm, porosity: 60-70%, through-hole rate:＞80-95%, average sound absorption coefficient ā is between 125～4000 HZ.Obvious advantage and the effect implemented after this technology are: compared with prior art, what remedied filter can only filtration, purification, and the defective that can not absorb sound; This device volume is little, and particle and the short fiber of particle diameter and length＞0.9mm can be filtered and purify to application capable of circulation; The flowing water of realizing will containing in the military and civilian water treatment procedure short fiber and graininess suspension screens, filters, purifies and absorbs sound integrated.

Description of drawings

Fig. 1 is the sectional structure schematic diagram of the utility model embodiment;

Wherein: 1-housing, 2-III level foamed aluminium filter, 3-II grade stainless steel filter silk screen, 4-I grade stainless steel screening silk screen, the circular U-lag of 5-, 6-threeway, 7-silently, the 8-straight-line groove

The specific embodiment

Below in conjunction with accompanying drawing, with embodiment the utility model is further described:

See accompanying drawing 1, whole device is fixed in the water system pipeline.In order, fixedly I grade stainless steel screening silk screen 4, II grade stainless steel filter silk screen 3 respectively, III level foamed aluminium filter 2 forms the foamed aluminium screen pack in the circular U-lag 5 of corresponding upper and lower two housings 1 and the straight-line groove 8.The foamed aluminium screen pack is inserted in the threeway 6, and threeway 6 top screws on silently 7 by screw thread.

See accompanying drawing 1, whole device is fixed on the pipeline front end that needs water treatment by connecting tube and threeway 6 two ends.The housing 1 end face outside is provided with circular U-lag 5 and middle straight-line groove 8, and circular U-lag 5 and middle straight-line groove 8 communicate; Housing 1 circular U-lag 5 and straight-line groove 8 are up, filter silk screen 3 at straight-line groove 8 interior insertion II grade stainless steels, in the groove of circular U-lag 5 left side semicircles of water inlet direction, insert semicircular I grade stainless steel screening silk screen 4, in the groove of circular U-lag 5 the right semicircles of water outlet direction, insert semicircular III level foamed aluminium filter 2, then the housing 1 circular U-lag 5 of establishing in addition and straight-line groove 8 are down, with I grade stainless steel screening silk screen 4, the II grade stainless steel filters silk screen 3, III level foamed aluminium filter 2 covers in the corresponding circular U-lag 5 of housing 1 end face and straight-line groove 8, form the foamed aluminium screen pack, the foamed aluminium screen pack is inserted threeway 6, screw on silently 7, water inlet is being screened silk screen 4 by the I grade stainless steel, the II grade stainless steel filters silk screen 3, the 2 rear water outlets of III level foamed aluminium filter are being advanced, in the exiting water process water is filtered, purify and pass through III level foamed aluminium filter 2 and absorb sound.

Claims (2)

1. noise reduction foamed aluminium filter, comprise that stainless steel filters silk screen, foamed aluminium board, housing, it is characterized in that: whole device is fixed on the water system pipeline enclosure, in order, fixedly I grade stainless steel screening silk screen, II grade stainless steel filter silk screen respectively, III level foamed aluminium filter forms the foamed aluminium screen pack in the circular U-lag of corresponding upper and lower two housings and the straight-line groove.
