Abstract
The oil immersed silencing filter includes casing, transmission mechanism, airflow inlet, airflow outlet, shutter set in the airflow inlet, oil immersed filter behind the shutter, silencer behind the filter and air outlet header tank in the back part of the casing. The oil immersed filter is provided with two chain wheels and chain on the wheels, the chain is connected to the filter screen board and positioned via the sleeve in the middle part, the filter screen board and the sleeve run synchronously, and the oil immersed filter has oil sump in the bottom. The silencer has several silencing sheets. The present invention has two functions of dust filtering and silencing, i. e., it can filter out dust from air and eliminate MF and HF noise of high speed airflow in diesel engine air intake channel.
Description
Technical field
The present invention relates to air-filtering, silencer, particularly a kind of oil immersed type noise reduction filter that is used for large and medium-sized medium speed diesel suction port.
Background technique
Medium speed diesel is higher to the inhaled air quality requirement, especially as the medium speed diesel of generator set, owing to the residing geographical environment of work, needs a kind of dirt dust filter of noise reduction again that should disappear of configuration.Some dust filters on the present China market, as LBZ type dust filter, LWZ type dust filter etc., these products only possess filter dirt, and do not have the function of noise reduction.
Therefore sieve plate in the existing filter often produces the fault that sieve plate is very easily blocked because of the chute skew owing to lean on the chute positioning trip of framework both sides when moving.
Summary of the invention
Task of the present invention provides a kind of improved oil immersed type noise reduction filter, its collection filter dirt and noise reduction two big functions are one, has solved existing product and has had only filter dirt and do not have the problem that silencing function and sieve plate are very easily blocked when moving.
Technological scheme of the present invention is as follows:
A kind of oil immersed type noise reduction filter, it comprises housing, driving mechanism, airflow inlet and flow outlet, it also is included in the venetian blind that airflow inlet is provided with, the oil immersed filter of in the housing of venetian blind back, settling, at the silencing apparatus of settling later of oil immersed filter, and the air outlet slit collection case that is provided with at the rear portion of housing; Described oil immersed filter is equipped with two sprocket wheels up and down and twines chain on it, and chain is connected with sieve plate by bearing pin, is located by sleeve in the middle of it, and sieve plate and sleeve synchronous operation are provided with oil groove bottom oil immersed filter; Described silencing apparatus is equipped with several bloops.
Oil immersed type noise reduction filter collection filter dirt of the present invention and noise reduction two big functions are one, dust in the filtered air effectively, middle and high audio-frequency noise noise reduction to middling speed diesel engine intake road high speed air-flow is better, can be matched in medium speed diesel preferably, play the effect of air-filtering and noise reduction in the medium speed diesel intake duct.
Filter of the present invention is compared with existing filter, and having to be driven by chain does not have frictionally synchronous operation in the space, it operates steadily, reliably, noiseless, long-time running does not have the advantage of damage.
Oil immersed type noise reduction filter of the present invention also can be used for the place of requirements such as blower, air compressor plant to air purification and noise reduction.

Embodiment
Referring to Fig. 1 and Fig. 2, a kind of oil immersed type noise reduction filter of the present invention comprises housing 1, driving mechanism 2, airflow inlet 3 and flow outlet 4.At airflow inlet 3 venetian blind 5 is set, in the housing of venetian blind 5 back, settles oil immersed filter 6, settle silencing apparatus 7, air outlet slit collection case 8 is set at the rear portion of housing 1 in the back of oil immersed filter 6.
Referring to Fig. 3 and Fig. 4, oil immersed filter 6 is equipped with upper sprocket wheel 61 and lower sprocket 62, is twining chain 63 between two sprocket wheels 61,62 up and down, and chain 63 is connected with sieve plate 65 by bearing pin 64, is located sieve plate 65 and sleeve 66 synchronous operations in the middle of it by sleeve 66.Sieve plate 65 adopts Mild Steel Expanded Sheets to make skeleton, the two-layer Stainless Steel Cloth of Mild Steel Expanded Sheets surface coverage, and its advantage is in light weight, good rigidly.In sieve plate 65 lower ends a rotating shaft is housed, when sieve plate 65 operations, can plays positioning action.
Sieve plate in the oil immersed filter directly drives smoothly operation by chain, sieve plate and chain synchronous operation during work.But its support equipment safe operation has been eliminated sieve plate in other type filter because of the chute positioning trip by the framework both sides, and often produces because the chute skew makes the fault that web plate very easily blocks when operation.
Wood side-guide steel pipe 91 and back wood side-guide steel pipe 92 before being equipped with in the filter 6, rotating shaft and slide rail steel pipe are formed Vertical location.Sieve plate 65 adopts the method for operation of slide rail location, and the slide rail steel pipe is formed Vertical location in the steel pipe rotating shaft of sieve plate 65 lower ends and the filter, and the location is reliable during operation, and the frictional resistance loss is little.
Be provided with oil groove 67 in the oil immersed filter bottom.Be respectively equipped with pouring orifice 68 and escape valve 69 at oil groove 67 positions.Dust in the sieve plate 65 adsorbable air-flows, sieve plate 65 run down in the oil groove 67 and by machine oil sieve plate 65 are cleaned, and play airfiltering effect.
Referring to Fig. 5 and Fig. 6, silencing apparatus 7 is equipped with several bloops 71.Bloop 71 is made of the ultra-fine fibre glass cotton 73 and the positioning plate 74 of perforated plate 72 and arrangement in perforated plate 72.The positioning plate 74 that is welded on bloop 71, so that guarantee the cross section of air-flow path in the silencing apparatus during loading and unloading bloop, the erasure effect of silencing apparatus 7 is unlikely to be affected because of the dismounting bloop.
Access door 75 also is housed on the silencing apparatus 7, opens access door 75 and can dismantle bloop 71 easily and check.Silencing apparatus 7 adopts the multi-channel type dissipative muffler, but the middle and high audio-frequency noise that the effective attenuation high velocity air produces.
In oil immersed filter 6 intermediate isolating filter screen 9 is housed between silencing apparatus 7, to guarantee the quality of filtered air.Bottom at air outlet slit collection case 8 is provided with air vent 81.
Driving mechanism of the present invention is selected motor and plane table thermoconductivity meter for use, adopts gear reducer can reduce from the noise that turns round, and the noise that the worm type of reduction gearing used with having other type dust filter now produced is in the running compared, and has tangible advantage.
Oil immersed type noise reduction filter working procedure of the present invention is as follows:
After the motor of driving mechanism slows down by plane table thermoconductivity meter, by cycle operation about the chain speed drive slowly sieve plate, when flow of outside air enter filter and by slowly move be positioned at sieve plate after oil is soaked in the filter bottom time, because air-flow is to the absorption of oil film on the high velocity impact of multistorey strainer mesh and the filter screen, airborne dust is trapped on the filter screen, after the filter screen that adheres to dust moves to downwards and washs in the oil groove, upwards move the dust in the absorbed air once more, cleaned air after the filtration enters silencing apparatus after by the intermediate isolating filter screen, enters the intake duct of medium speed diesel through the air stream of noise reduction.
