Wall-hung thin type lampblack depurating machine

Abstract

The invention discloses a wall-hung thin type lampblack depurating machine, which is provided with flat cuboid-shaped shell, wherein a double-volute is arranged in the shell, and two isolated chambers of the double-volute share an air outlet passage on the top of the shell; a turbo-fan with a horizontal output shaft is arranged in the two isolated chambers of the double-volute respectively, and the front end of the output shaft of the turbo-fan extends out of the double-volute and is connected with at least one vertical rotary centrifugal filter screen plate; and the outside of the rotary centrifugal filter screen plate is provided with an annular oil guide ring, the bottom of the annular oil guide ring is provided with an oil leak opening, a fume flow distribution plate is arranged below the annular oil guide ring, an oil guide tank is arranged on the fume flow distribution plate, and the bottom of the shell is provided with an air inlet passage and an oil collection box. The wall-hung thin type lampblack depurating machine has ultra-high efficiency for holding up and collecting lampblack, can basically put an end to the pollution caused by the lampblack to the air, the shell and the external wall of a building, and has the characteristics of overall closure, simple structure, convenient cleaning, energy saving and noise reduction, large cooking space, safe running and long service life.

Description

technical field [0001] The invention relates to equipment for treating oil fume discharged from catering industry or family kitchen, in particular to a wall-mounted thin oil fume purifier mainly installed on the wall above the kitchen stove. Background technique [0002] With the increasing awareness of environmental protection of the general public, the requirements for themselves and the surrounding environment are getting higher and higher, and the prevention and control of air pollution has become a top priority. Relevant survey data show that among the air pollutants in large and medium-sized cities, the pollution caused by catering industry and household oil fume has exceeded that of automobile exhaust. About 40-50% of the air pollutants are kitchen oil fume pollution. The problem of oil fume pollution has become a The focus of today's environmental protection. [0003] At present, there are various types of devices for kitchen oil fume treatment, and a considerable p...

AI Technical Summary

Problems solved by technology

This type of device can directly exhaust indoor oil fumes to the outside. Its advantage is that it has a good exhaust effect in the early use, but many problems have appeared with the extension of time: First, the direct exhaust fan and exhaust Range hoods do not have the function of intercepting or purifying oily fume. When the oily fume is directly discharged outside, it not only pollutes the air, but also pollutes the facade of buildings, seriously affecting urban environmental sanitation and people's health.

Since the motor and fan of the side-suction range fume purifier are actually installed on the top of the machine casing, there is a considerable distance between its air inlet and the motor and fan blades, and the air inlet is very close to the stove, and the inner wall of the casing often It will be polluted by waste oil, causing a large amount of uneven oil accumulation on the fan impeller, and the fan will lose its dynamic balance, so its suction effect will naturally become worse and worse, and its mechanical noise will also become louder

If things go on like this, the device is easily damaged

[0008] Second, heat energy and cooking space are lost, and there are potential safety hazards

Although this intuitively ensures the cleanliness and beauty of the outer surface of the building, due to the lack of effective purification treatment of oil fumes, the centralized exhaust pipes cannot fundamentally solve the problem, and the pollution caused by high oil fume emissions to the air environment is still serious. Moreover, there are problems such as poor smoke exhaust, backflow of smoke, odor, breeding of mosquitoes and rodents, etc.

[0011] Moreover, the projected area of ​​the air inlet of the traditional oil fume purifier, no matter it is the top suction type or the side suction type, is fixed, and most of them directly cover the two ignition stoves on the stove, but In fact, when the user uses it, the probability of two ignition stoves working at the same time is relatively small. The lampblack purifier will inevitably inhale a lot of natural air and do a lot of useless work, resulting in low efficiency of lampblack purification.
