Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collector having a spiral collecting part and an oil-

The present invention relates to a dust collector having a spiral collecting part and an oil-melting part, and more particularly, to a dust collector having a spiral collecting part and an oil-melting part, Drain valves are arranged in order to discharge the oil to the outside, and the oil to be solidified in the inner wall is melted so as to be easily discharged, and to a dust collector having the spiral oil collecting part and the oil melting part.

In Korea, there has been a lot of changes in diet as well as in economic growth, in particular, the increase in meat consumption due to the introduction of western eating habits. This can be seen not only in the home, but also in the food service industry, as the meat consumption increases. This increase in meat consumption has resulted in diverse food cultures, but one of the main causes of meat consumption is roasting. This grilling is a typical appearance of a restaurant company that specializes in meatballs that generate dust, soot and oil (oil mist) during the process of baking meat and discharge it out through a duct.

On the other hand, in the case of the oil mist dust collector, it is a device configured to separate air and air separately by sucking air, that is, oil mist, containing a large amount of oil particles generated in various industrial sites or restaurants. Since the discharged oil can be collected and recovered separately and can be recycled and purified air can be discharged, the operation environment can be kept fresh, and the utilization thereof is very high, so that an oil mist dust collector is used in various industrial fields. Conventional oil mist dust collectors can be roughly divided into filter filtering method, centrifugal separator and electrostatic separator type dust collector. The dust collector of the filter filtration type is the most general type of dust collector, and a blowing fan and a filter filter are installed in the body to suck the oil mist, filter the impermeable oil particles by the filter, and discharge only the purified air. In addition, the centrifugal dust collector is configured to separate the oil and the air by using a centrifugal force to form a rotating air flow by using a centrifugal separator. Since the shape and configuration of the centrifugal separator can be differentiated according to the nature of the separation object, it is necessary to develop a most suitable and efficient configuration. Further, the dust collecting device of the electrostatic force separation type is configured to charge the oil mist to agglomerate and separate the oil particles.

As a prior art of a dust collector having such a centrifugal separation method and a filter filtration method, there is disclosed a registered utility model publication No. 20-0418713. In constructing the interior of the main body, a blowing fan is installed at the upper part and the lower part, The mist is centrifuged, filtered by a filter at the top, and purified air is discharged.

The problems of the background art described above are as follows.

First, due to the fact that the conventional dust collectors for restaurants are sold at a burdensome amount to be used in large-sized and small restaurants, and there is no legal regulation standard for air pollutants, The generated gas is discharged to the outside without treatment. The fine dust discharged to the outside causes direct health hazards to the human body including harmful air pollutants such as ruins and various organic aerosols and unburned carbon pollutants, and causes secondary pollution .

Secondly, in the case of the dust collector of the above-described filter filtration method, since the filter has to be frequently replaced in order to increase the filtration efficiency, there is a problem that it is uneconomical in terms of the maintenance cost.

Third, centrifugal type dust collectors can lower the maintenance cost compared with the filter filtration method, but the filtration efficiency is also lowered so that the fine particles can not be separated.

Fourth, the above-mentioned Registration Utility Model No. 20-0418713 has attempted to increase the filtration efficiency by combining the two different separation methods, but due to the structural limitations of the internal components, smooth flow of airflow is not formed between the lower and upper portions, There is a problem in that at least one blowing fan must be installed. In addition, since the motor for driving the blowing fan is directly exposed to the flow path of the airflow, there is a problem that the service life of the device can be shortened due to the oil being sucked.

Fifth, since the filtered oil is solidified before being discharged to the outside of the dust collector, it sticks to the inside of the dust collector or the filter, and the efficiency of the dust collector is lowered due to the solidified oil or the replacement period of the filter is shortened.

Conventional dust collectors generally have a problem in that the conventional dust collectors for restaurants are generally sold at a burdensome amount for use in a large and small dining room and that there is no legal regulation standard for air pollutants The gas generated in the roasting is discharged to the outside without treatment. The fine dust discharged to the outside causes direct health hazards to the human body including harmful air pollutants such as residues and various organic aerosols and unburned carbon pollutants, There is a problem that pollution is caused. In the case of the dust collector of the above-described filter filtration method, since the filter must be frequently changed in order to increase the filtration efficiency, there is a problem that it is uneconomical from the viewpoint of maintenance cost and the centrifugal dust collector has a problem Maintenance costs can be reduced, but filtration efficiency is also reduced. And the above-mentioned Registration Utility Model No. 20-0418713 has attempted to increase the filtration efficiency by combining two different separation methods. However, due to the structural limitations of the internal components, A smooth flow of the air current is not formed, so that at least one blower fan is inevitably installed. In addition, since the motor for driving the blowing fan is directly exposed to the flow path of the airflow, there is a problem that the service life of the device can be shortened due to the oil being sucked. Further, since the filtered oil is solidified before it is discharged to the outside of the dust collector, it sticks to the inside of the dust collector or the filter, and the efficiency of the dust collector is lowered due to the solidified oil or the replacement period of the filter is shortened. In order to solve the problems, the present invention provides step-by-step filtering, improves the efficiency of filtration by changing the pores of the filter, introducing a centrifugal separation method, etc., And a melting portion. Hereinafter, the components will be described in detail.

1, a dust collector having a spiral collecting part and an oil-melting part according to an embodiment of the present invention includes an intake part 100 in which an intake port 110 is formed, a spiral dust collecting part 200 and an exhaust port 310. The intake unit 100 includes a suction port 110 and an intake fan 120 connected to the rear end as a cylindrical shape and connected to the front end The spiral flow collecting part 200 includes a filter 130 and a first drain valve 140 connected to the lower end of the front end of the spiral flow collecting part 200. The spiral flow collecting part 200 has a cylindrical shape A screw guide 220 formed at the front and rear ends of the body 210 so as to be spaced apart from the wall of the body 210 and a screw guide 220 connected to the screw guide 220 and formed so as to form a spiral flow path from the rear end to the front end, A screw 230 is formed between the screw guide 220 and the wall of the body 210 And a second drain valve 250 formed at a lower end of the body 210. The exhaust part 300 is connected to the front end and the rear end of the helical collecting part 200 so as to correspond to each other, A supporter 330 connected to a cover 320 having a vent 310 formed at a front end thereof and formed to cross the center of the vent 310 formed in the cap 320, A cylindrical wrinkle filter (not shown) having a center of support base 330 and a closed bottom surface 342 connected by a shaft 344 and having a bottom surface 342 closed and a finer porosity than the void of the foam filter 130 A third drain valve 350 connected to the lower end thereof, and an exhaust fan 360 connected to the cover 320 for forcibly discharging the air to the outside.

The intake unit 100 is connected to a duct D through which air pollutants discharged from a restaurant or the like are moved and primarily filters the intake unit 100. The intake unit 100 has a cylindrical shape and is connected to an intake port A suction fan 120, a foam filter 130 connected to the front end portion, and a first drain valve 140 connected to the lower end of the front end portion. That is, the intake port 110 and the intake fan 120 are mounted on the rear end of the cylinder, air containing air pollutants is sucked and transferred to the front end, and a foam filter 130 is mounted on the front end, The oil filtered by the first drain valve 140 is discharged to the first drain valve 140 connected to the lower part and the first filtered air is moved to the spiral oil collecting part 200 which is the next step. The details of each component are as follows.

The air inlet 110 is connected to the duct D and corresponds to a hole through which the air containing the air pollutant is sucked. The intake port 120 is connected to the intake port 110 to force the air to be inhaled so that the exhaust fan 360 of the exhaust unit 300 is connected to the centrifugal separation of the oil of the spiral- Thereby providing a necessary rotational force. The intake port 110 and the intake fan 120 may be connected in the order of the duct D, the intake port 110 and the intake fan 120 in this order, and may be connected to the duct D, the intake fan 120, 110).

The foam filter 130 is a means for primary filtering, and a foam filter such as a sponge can be used. And is larger than the pore of the cylindrical wrinkle filter 340 which is the last or third-order filtering means since it is the primary filtering means. The reason for this is that because the air is polluted firstly in the air because it is the first to be filtered, if it is tried to filter all of the air pollutants, it takes a long time for filtering, and there are many problems in the replacement period and management of the filter. . Therefore, in the first primary filtering step, only the thickest particles among the air pollutants are filtered, and then the small particles are allowed to have larger pores than the pores of the cylindrical wrinkle filter 340, which is a tertiary filtering means, . The suction port 110 of the suction unit 100 is connected to the rear end of the suction unit 100 in the form of a cover 320, The foam filter 130 connected to the front end of the intake unit 100 can be exposed by separating the cover 320 so that the foam filter 130 can be easily replaced.

The first drain valve 140 serves as a passage through which the oil filtered by the foam filter 130 is discharged to the outside. Also, since the valve can be opened and closed, a certain amount of oil can be stored in the lower portion of the intake unit 100, and the oil discharge timing and the like can be adjusted according to the operator's selection.

The helical oil collecting part 200 makes the air flow spirally and filters the oil by a centrifugal separation method and becomes a secondary filtering means. The helical collecting part 200 includes a cylindrical body 210 connected to the front end and the rear end of the intake unit 100 so as to correspond to each other, a screw 210 spaced apart from the wall of the body 210 at the front and rear ends, A guide 230 connected to the screw guide 220 and formed to have a helical flow path from a rear end portion to a front end portion thereof, a water collecting chamber 230 formed between the screw guide 220 and the body 210, 240 and a second drain valve 250 formed at the lower end of the body 210. [ We will examine each component in detail.

The body 210 serves as a housing for forming a cylindrical outer shape and is connected to the rear end and the front end of the intake unit 100 and the exhaust unit 300, respectively. It also serves as a flow path for air.

The screw guide 220 fixes the screw 230 so that the screw 230 is positioned at the center of the body 210. The screw 220 guides the collecting chamber 240 Thereby providing a place for oil to be stored. The screw guide 220 is spaced apart from the wall of the body 210 and is formed along the wall as a cylindrical shape of the body 210. In this way, the chamber formed by the screw guide 220 spaced apart from the wall of the body 210 becomes the collecting chamber 240. The screws 230 are formed on the front and rear sides of the body 210 so that the screws 230 are connected to the screw guides 220 formed on the front and rear sides of the body 210 to fix the screws 230 .

The screw 230 serves to guide the air containing the air pollutant to rotate in the direction perpendicular to the longitudinal direction of the body 210. The screw 230 may be provided in the front and rear of the body 210, The blades of the screw 230 are fixedly connected to the screw guides 220 connected to the rear side and are formed to have a helical flow path from the rear end to the front end. That is, the structure of the screw 230 is composed of a blade and a central axis. As described above, the blade can be connected to and fixed to the screw guide 220 formed at the front and rear of the body 210, The blade is helical and connected to the central axis. With this structure, the screw 230 forms a helical flow path from the rear portion of the body 210 to the front portion.

The reason for forming such a spiral flow path is to impart the rotational force while moving the air along the spiral flow path, and as the air rotates, the oil particles which are heavy particles in the air are biased toward the outermost rotation, And the oil is adhered to the wall of the body 210 by such contact, thereby being filtered. That is, centrifugal filtering. In this case, in order to increase the efficiency of the filtering, it is possible to propose a method of widening the contact area with the wall of the body 210 while giving less influence to the rotational force of the air. A number of impingement plates having a height of 0.5 to 2 cm and a length of 5 to 10 cm may be formed so as to be perpendicular to the flow direction of the impingement plate, and the impingement plate may have a plurality of holes. That is, it is possible to increase the efficiency of filtering by increasing the contact with the air.

The housing chamber 240 is a space between the screw guide 220 and the inner wall of the body 210 and is temporarily stored in the housing chamber 240 after the air is filtered by the centrifugal separation method . The stored oil is discharged to the outside through the second drain valve 250.

The second drain valve 250 is formed at a lower end of the collecting chamber 240, that is, at a lower end of the body 210. The second drain valve 250 is a passage through which the oil stored in the collecting chamber 240 flows out. So that the time can be adjusted.

The exhaust unit 300 serves to filter the air passing through the helical collecting unit 200 and finally to be discharged to the outside. The exhaust unit 300 is connected to the front end of the helical collecting unit 200 so that the front end and the rear end of the helical collecting unit 200 correspond to each other. A center of the support base 330 and a closed bottom face 342 of the support base 330 are connected by a shaft 344 and a bottom face 342 of the support base 330 is connected to the center of the exhaust hole 310, A cylindrical drain valve 350 connected to the lower end of the cylindrical wrinkle filter 340 and a cylindrical wrinkle filter 340 having a narrower space than the air gap of the foam filter 130, And an exhaust fan 360 for forcibly discharging the exhaust gas.

The shape of the exhaust part 300 is cylindrical in shape like the shape of the body 210. This is because the front end of the body 210 and the rear end of the exhaust unit 300 are connected to each other.

The lid 320 is formed at a front end of the exhaust unit 300 and has an exhaust port 310 for discharging air to the outside and serves to fix the cylindrical wrinkle filter 340. [ The lid 320 is connected to the front end of the lid 300. The lid 320 is formed with the exhaust port 310 and the exhaust fan 360 can be connected thereto.

The support base 330 serves as a support for fixing the cylindrical wrinkle filter 340. The center of the support base 330 and the center of the closed bottom surface 342 of the cylindrical wrinkle filter 340 and the shaft 344 are formed so as to cross the center of the exhaust port 310 of the lid 320, .

The cylindrical wrinkle filter 340 is a tertiary filter as the last filtering means. The cylindrical wrinkle filter 340 forms a cylindrical wall and the cylindrical wall forms a wrinkle filter in a closed shape on the bottom surface 342. And is connected to the center of the bottom surface 342 and the center of the support base 330 by a shaft 344 so that the cylindrical wrinkle filter 340 contacts the lid 320. That is, the air passing through the helical collecting part 200 is filtered while passing through the pleated filter formed on the cylindrical wall while being moved to the side by contacting the bottom surface 342. The cylindrical wrinkle filter 340 forms a pore smaller than the pore of the foam filter 130 to filter the air pollutants of fine particles remaining in the air subjected to the first and second filtering by the last filtering means to be. The reason why the difference in the air gap is provided is to increase the efficiency of filtering as described above. (If the filter having a narrow gap is used in the first filtering process, air can be accumulated by slowing the flow rate of the air, The exchange cycle of the power supply is often frequent)

The third drain valve 350 serves as a passage through which the oil filtered by the cylindrical wrinkle filter 340 is discharged to the outside and is connected to the lower end of the exhaust unit 300.

The exhaust fan 360 is connected to the exhaust port 310 of the cover 320 to provide power for discharging the primary, secondary, and tertiary filtered air to the outside. It is also a means for providing the rotational force of the air in the secondary filtering process.

The oil melter 400 may further include an oil melter 400 formed in the intake unit 100, the helical oil collecting unit 200, and the exhaust unit 300, The spiral collecting part 200 and the exhaust part 300 along the line connecting the valve 140, the second drain valve 250 and the third drain valve 350, A first heating line 420 formed in a round shape through the first drain valve 140 along a cylindrical inner wall of the intake unit 100, a second heating line 420 formed in a cylindrical shape of the helical collecting unit 200, A second heat line 430 formed in a round shape through the second drain valve 250 along the inner wall of the exhaust part 300 and a third drain valve 350 formed through the third drain valve 350 along the cylindrical inner wall of the exhaust part 300 And a third heat line (440), wherein the heat line is maintained at a temperature of 30 to 50 DEG C, And a temperature controller capable of changing the temperature according to the type of oil contained.

The oil-melted portion 400 is formed by coagulating and bonding the oil filtered by the dust collector having the spiral collecting portion and the oil-melting portion according to an embodiment of the present invention to the inner wall of the dust collector (particularly, the inner wall of the body 210) It melts and smoothly discharges it to the outside. To this end, it is possible to provide the bottom of the dust collector having the spiral collecting part and the oil-melting part according to the embodiment of the present invention, and the hot line respectively along the wall. The oil to be used in the meat baking shop is usually pork oil, beef oil, chicken oil, duck meat oil, etc. Since the oil has a melting point of 30 to 50 ° C, . However, since the melting point of each meat is different, the melting point of pork oil is 33-36 ° C, and the melting point of beef oil is 40-48 ° C. Accordingly, since the melting point of each kind of oil (oil) is different, it is possible to provide a temperature controller for adjusting the temperature of the heat ray accordingly. Such a temperature controller can be operated without generating excessive heat, which is efficient in terms of energy saving. The first heat line 420, the second heat line 430 and the third heat line 440 are formed in a ring shape along each cylindrical inner wall to melt the oil which is solidified and bonded to the inner wall, By forming a flow path, it is possible to help smooth oil discharge. Particularly, the second heat line 430 must be formed in a large area, which is different from the first heat line 420 and the third heat line 440 The second heat line 430 has a plurality of strands of heat rays formed on the inner wall of the body 210. At this time, if the second heat line 430 is formed to pass through the second drain valve 250, the portion where the second heat line 430 is disposed and its periphery are melted, So that the oil melted in the periphery can flow into the second drain valve 250 along the flow path. This structure is also applicable to the first heating line 420 and the third heating line 440. When the structure is formed as described above, the entrances of the first drain valve 140, the second drain valve 250, and the third drain valve 350 and the flow path therefrom can be prevented from clogging due to the solidification of oil .

In addition to the heating line, the oil-melting part 400 is connected to a duct D through which the air is sucked, is drawn into one end of the collecting chamber 240, passes through the collecting chamber 240, And an oil-melting pipe (450) drawn out from the end portion and connected to the air intake port. This is shown as a method for increasing the efficiency of the oil-melting part 400, and the air in the duct D is high in temperature because it is air heated by frying meat. The oil-melted pipe 450 connected to the duct D is connected to the lower end of the collecting chamber 240 through a pipe (not shown) And melts the oil solidified at the lower end of the collecting chamber 240 by the thermal energy of the air passing through the oil-melting pipe 450, thereby discharging the oil to the outside.

The inner wall of the lower portion of the intake unit 100 forms a downward gradient toward the first drain valve 140 and the inner wall of the lower portion of the helical collecting unit 200 The wall forms a downward slope toward the second drain valve 250 and the inner wall of the lower portion of the exhaust portion 300 may form a downward slope toward the third drain valve 350 have. This is because in the present invention, the oil filtered at each step is collected at the lower end, and when the gradient is directed from the lower end toward the drain valve corresponding to each step, the filtered oil is easily moved to each drain valve, It is possible to reduce the absolute amount of solidification and consequently to have a positive effect on the increase of the efficiency and the life extension of the present invention.

The dust collector having the spiral dust collecting part and the oil melting part according to an embodiment of the present invention discharges the gas generated during roasting without any treatment, thereby causing a direct health hazard to the human body The present invention can reduce the size of the dust collector, simplify the structure of the dust collector and simplify the installation, and can be installed in a small restaurant without any cost, And a multi-stage separation process from suction to discharge is provided by providing a centrifugal collecting section at the center of the present invention, a foam filter having a large gap at the rear, and a wrinkle filter having a small gap at the front at the rear. So that efficient separation can be achieved, and a foam filter having a large rear space and a small front space At the same time as an efficient separation yirueojim by providing flow filter has the effect that a refresh cycle extension of each filter. In addition, the number of fans can be reduced by a simple structure, the installation thereof is easy, and a motor providing the driving force of the fan can be installed outside, thereby achieving structural stability and also extending the life of the dust collector .

The present invention may be embodied in many other specific forms without departing from the spirit or essential characteristics and scope of the invention.
