Description

A kind of filtration silencing means of lampblack absorber

Technical field the utility model relates to a kind of lampblack absorber that purifies air in kitchen, and in particular, the utility model relates to a kind of filtration silencing means of lampblack absorber.

The background technology lampblack absorber claims oil and smoke cleaner, smoke exhaust ventilator, range hood, range hood etc. again.It is " oil and smoke cleaner and electric fan are selected for use and keeped in repair " book of ISBN 7-115-05355-3/TN761 that the People's Telecon Publishing House published book number in 1996, introduced the method for maintaining of structure, principle, characteristics and the most common failure of public lampblack absorber, substantially represented structure, principle, the type of selling lampblack absorber on the market, the document of reporting similar lampblack absorber is a lot of.The structure of this type of lampblack absorber is to constitute air exhauster by motor, fan and air guide hole etc., forms exhaust fume collecting hood by casing, by the work of control system control air exhauster.Its principle is to utilize the driven by motor fan to rotate at a high speed oil smoke and other waste gas from indoor direct row to outdoor, maybe will suck oil flue waste gas and be discharged to outdoorly through filtration again, also can directly be emitted on indoor.Purify the purpose that air in kitchen reduces disposal of pollutants for reaching, this type of lampblack absorber is provided with guard or oil suction net or oil-Absorbing Sheets at air entry oil flue waste gas is simply once filtered, the part lampblack absorber is also filled material filter courses such as active carbon at exhaust outlet, oil flue waste gas is carried out secondary filter, the family of or long-time use excessive to oil smoke can not thoroughly purify.Simultaneously, the noise that produces during lampblack absorber work causes very big harm all for user and environment.

Summary of the invention the utility model overcomes the prior art deficiency, and providing a kind of can carry out multiple times of filtration to oil flue waste gas, produces the device of noise in the time of reducing lampblack absorber work again.

For solving the problems of the technologies described above, the utility model adopts following proposal to be achieved.

The filtration silencing means of the utility model lampblack absorber comprises filter cylinder, filter core cylinder, smoke guiding cover, Smoking pipe, filtrate, described hush pipe is arranged in the interior comb, filter core is arranged in the filter core cylinder, filter core cylinder is positioned at the filter cylinder upper end, Smoking pipe is arranged on lower end in the filter cylinder, smoke guiding cover is arranged between filter cylinder and the Smoking pipe, between hush pipe and the casing, be provided with O-ring seal between filter cylinder and the casing, hush pipe is connected with the casing upper end, interior comb is connected with hush pipe, and Smoking pipe is connected with filter cylinder, and filter cylinder is connected with fan lower end casing.

Described hush pipe is horn-like, the even tube wall several rows of aperture that distributes; Described filter core is made up of particulate filter and purifying layer, and particulate filter is materials such as cotton fiber, asbestos fibre, glass fibre; Purifying layer is filled charcoal, bamboo charcoal, activated carbon granule.Two-layer material is with holey material parcel, with filter core cylinder internal diameter one to; The filter cylinder bottom is hemispherical, and the bottom hits exactly the opening that caves in and is connected with a Smoking pipe in the tube; Described device adopts the liquid filtering oil flue waste gas: described filtrate be family expenses vegetable oil, water or non-foaming detergent solution any; Described filtrate, filter core can regularly replace; Described smoke guiding cover top is the spherical crown shape, and the protruding injustice of bottom cover emargination has the smoke evacuation gap; Described Smoking pipe, smoke guiding cover, filter cylinder are concentric structure, and three layers respectively is the space.

The utility model compared with prior art has following advantage:

1, simple structure is easy to make, and is with low cost;

2, the filter oil smoke waste gas, to fall end noise result obvious, can effectively protect environment;

3, filtrate, filter core can regularly replace, and have guaranteed result of use;

4, device integral body is column, and volume is little, and it is convenient to clean.

Description of drawings Fig. 1 filters the silencing means generalized section for lampblack absorber;

Fig. 2 filters silencing means A-A profile for lampblack absorber;

Fig. 3 filters silencing means suction process schematic block diagram for lampblack absorber.

Among the figure: interior comb 1, hush pipe 2, exhaust outlet 3, aperture 4, motor 5, fan 6, air guide port 7, filter core 8, purifying layer 9, particulate filter 10, filter cylinder 11, smoking port 12, smoke guiding cover 13, Smoking pipe 14, filtrate 15, filter core cylinder 16, cushion rubber 17, casing 18, indicating window 19.

The specific embodiment is further stated the utility model below in conjunction with accompanying drawing.

Among Fig. 1, filtering silencing means is single air channel structure, filter cylinder can adopt material blowings such as metal, plastics, pottery, draw or be stamped to form, filter cylinder 11 is connected with fan 6, casing 18 lower ends, interior comb 1 is connected with casing 18, in the comb 1, hush pipe 1 wall is the several rows of aperture of distribution evenly in hush pipe 2 was arranged on.First end is a filter core cylinder 16 in the filter cylinder 11, is used to place filter core 8.Filter core 8 is for being filled in cotton fibre, asbestos, glass, charcoal, the activated carbon material in the holey material, and filter core 8 can regularly replace.Smoke guiding cover 13 covers on the Smoking pipe 14, the top is spherical crown shape, the protruding injustice of bottom cover emargination, be beneficial to smoke evacuation, smoke guiding cover 13 can be fixed on the filter cylinder 11, can not fix yet, unfixed effect is that when negative pressure is too high in the filter cylinder 11 smoke guiding cover 13 is sucted a liter obstruction discharge flue and lowers cylinder pressure.Filtrate 15 indicating windows 19 are set on the filter cylinder 11, on the indicating window 19 graduation apparatus are arranged, be used to indicate liquid level, indicating window 19 can also in time be observed filtrate and whether clean, and is convenient to timely replacing.

Among Fig. 2, filter cylinder 11, smoke guiding cover 13, Smoking pipe 14 are concentric structure, and three layers respectively is the space.

Shown in Fig. 3 is that lampblack absorber filters silencing means suction process block diagram.

Below in conjunction with Fig. 1 and Fig. 3 lampblack absorber filtration noise reduction process is further described.

Connect power supply, motor 5 drives fan 6 rotations, fan 6 produces negative pressure, oil flue waste gas enters Smoking pipe 14 by smoking port 12, through smoke guiding cover 13, oil flue waste gas is imported in the filtrate 15, and in filtrate 15, oil flue waste gas is through cooling and dissolving, be partially soluble in the filtrate 15, not consoluet oil flue waste gas rises along filter cylinder 11 and enters in the filter core 8, and smoke stratification 10 filters after filtration earlier, continues to be cleaned layer 9 again and purifies, 99.99% oil flue waste gas is cleaned, the air that has purified enters fan and is got rid of in the air guide port 7 motor 5 fast, fan 6 and filtrate 15 produce noise and enter hush pipe 2 with high velocity air, and the aperture 4 on hush pipe 2 tube walls enters in the interior comb 1 the part air-flow, consumed portion of energy, pressure, density and speed reduce greatly, and this has just lowered the impulsive force of air to external world, thereby sound is weakened greatly.
