Description

A mechanical oil fume purifier

technical field

The utility model relates to the technical field of a mechanical oil fume purification device for separating oil fume from air.

Background technique

Existing service industries such as restaurants, guesthouses, and fast-food stores will generate a large amount of oily fumes and waste dust during work, and most of them are directly discharged into the outdoor air only through general range hoods, so it is inevitable to cause environmental pollution. Air pollution affects urban air and people's daily life. For this reason, many scientific and technical personnel design and develop novel mechanical oil fume purifiers, such as "a kind of oil fume purification device" whose patent number is 99201140. There is a fryer or other barbecue equipment, the cover body is equipped with a centrifugal smoker, the device is equipped with a centrifugal fan, the top is a filter, and the device is equipped with a filter element. When there is oily smoke, the utility model can be used to remove the oily smoke. and harmful gases, the oil and gas are roughly separated first, and then forced to filter to eliminate the environmental pollution of oily fumes and harmful gases. After all, the purification effect is limited and needs further improvement. Also have the Chinese patent " kitchen oil fume waste gas purifying device " that is 00239196.1 as the patent No., and it comprises casing, blower fan, inlet and outlet, pipe and is made up of. In the casing, there are inlet guide parts, spray devices, adjustable separation and drying parts, automatic cleaning mesh filter parts between the spray devices, and water tanks, oil-water separators and water pump units at the bottom of the casing. The shower technology reduces the temperature of the fume exhaust gas, and condenses into oil droplets and washes it down. The purified gas is discharged by the fan. The structure is simple and has a good purification effect. Due to the use of liquid spray absorption, the separation effect is good, but it requires a liquid spray device and a liquid flow channel, resulting in a relatively complex structure, inconvenient use, and bulky volume. Such as the Chinese patent "Restaurant Oil Fume Purifier" with the patent No. 97247738.1, it has a cyclone air duct, a purification body is set under the cyclone air duct, an adsorption filler is arranged in the purification body, a liquid storage tank is established under the purification body, and the liquid storage tank One end of the infusion tube is connected to one end of the infusion tube, the other end of the infusion tube is connected to the inlet end of the circulation pump, the outlet end of the circulation pump is connected to one end of the valve, the other end of the valve is connected to one end of the infusion tube, and the other end of the infusion tube is connected to the spray pipe. There are several atomizers on the shower pipe, one end of the cyclone air pipe is connected to the fan, and the fan is connected to the motor. The outer wall of the box is equipped with a vent valve and a liquid inlet valve. It has the advantages of reasonable structure, good purification effect, and easy promotion. . The significance of its progress lies in the use of fans and cyclone ducts to separate the fluid by its own centrifugal force, but it is limited to its own wet absorption principle, resulting in complex structure, large volume, inconvenient installation and use, and high cost.

Contents of the invention

The technical problem to be solved by the utility model is to provide a mechanical oil fume purifier with simple structure, convenient use and maintenance, and good effect of separating oil fume and oil dust.

The technical problem of the utility model is solved in this way: this kind of mechanical oil fume purifier includes a housing, an air inlet, an air outlet and a flue, and a fan for extracting fume and a fan for the exhaust gas are installed in the housing. A filter composed of filter materials for separating oily smoke and air, characterized in that a motor is installed in the flue of the casing in front of the above filter, and an impeller is fixed on the motor shaft to form a fan, and at the same time, a collector is installed in the casing behind the impeller. Oil ring, the lower part of the oil collecting ring communicates with the oil collecting cup.

The oil fume purifier of the utility model uses the combination of centrifugal separation and filtration adsorption principle to process oil fume exhaust gas, so it avoids some common problems of wet method principle structure such as huge device, complex structure, inconvenient use and maintenance, and adds centrifugal separation, which is better than ordinary filter adsorption The effect of the method is better, so it has the advantages of small size, simple structure, convenient use, low operating cost, convenient maintenance, etc., and is suitable for popularization and use in oil fume purifiers.

Specific implementation method

Embodiments of the utility model are described in further detail below in conjunction with the accompanying drawings.

As shown in the figure, this kind of mechanical oil fume purifier includes a housing 9, an air inlet 3, an air outlet 4 and a flue like a traditional oil fume purifier. A filter 1 composed of filter materials for separating oil fumes and air will not be described in detail here. Its special feature is that a centrifugal separator 2 is arranged in the housing in front of the filter 1, and its structure is that a The motor 5 can be fixed in the flue of the casing by using the cross-shaped rib frame 6, so that the oily fume flow passes through the gap of the cross-shaped rib frame under the twitch of the fan blades, reducing the airflow resistance, and the motor shaft is fixed There is an impeller 10 to form a fan, and the impeller 10 is composed of blades 13, blade reinforcement plates 12, and blade chassis 11, and the impeller is facing the air inlet to expand the air intake and improve its oil fume purification efficiency. An oil collecting ring 7 is provided, and the inner side of the oil collecting ring gradually expands to form a slope or an oblique arc surface, the purpose of which is to make the oil droplets move outward continuously and gather and grow under the centrifugal force of the cyclone, so as to improve the oil fume separation effect. Inside the inner side is a through hole for the airflow to pass through, and the outer side and the shell can be fixed with fasteners or the shell can directly become the outer side of the oil collecting ring, and a gap is opened in the lower part to communicate with the oil collecting cup 8 for easy separation The oil droplets flow into the oil collecting cup. In order to facilitate the maintenance of disassembly and washing, the oil collecting cup 8 is installed on the lower part of the housing through a detachable structure, such as bolted connection and fixing. The air outlet of the casing is upward through the air duct, and there is a rainproof cover on the air duct to prevent raindrops from entering, and is suitable for outdoor installation.

Its working principle is as follows: under the rotation of the motor in the air inlet of the casing, the impeller is driven to rotate, and the oil fume gas in the room is sucked into the flue. Under the centrifugal force of the cyclone, a part of the oil fume is separated into oil droplets, and the oil droplets are continuously formed. Centrifugal movement, and gathers to grow, is blocked in the oil collection cup behind the impeller, is intercepted, flows into the oil collection cup below, and a part of the oil fume that is difficult to separate by centrifugal force passes through the rear filter, It is separated and adsorbed by special oil-water separation fibers, and the basically purified air is discharged to the outside through the air outlet.
