Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a system diagram in which the dust collecting apparatus of the present invention is installed, and FIGS. 2 and 3 show longitudinal cross-sectional views of the dust collecting apparatus of the present invention.

Referring to Figure 1, the dust collector 10 of the present invention sucks the smoke generated by cooking in the cooking utensils (P) of the food establishment to the smoke hood pipe (1) to send to the dust collector (20) To be collected.

And the smoke generated by cooking in the cooking utensils (P) can be said to be a dusty smoke containing oil when roasting, for example, if such dust smoke is released into the atmosphere as it is, the dust itself contains oily This causes environmental damage.

Therefore, the dust smoke supplied to the dust collector 20 through the smoke hood pipe 1 is exhausted to the atmosphere by the exhaust fan 2 installed in the exhaust pipe 3, so the dust smoke supplied to the dust collector 20 is supplied. Is discharged to the atmosphere through the exhaust pipe (3) through the inside.

2 and 3, the dust collecting device 10 of the present invention has a vertical dust collecting space portion 12 in the body member 11 to allow the smoke to be exhausted from the upper side to the lower side,

The dust collecting space part 12 includes a first stage condensation collecting means 20, a second stage condensing collecting means 30, a third stage condensing collecting means 40, and a fourth stage condensing collecting means 30 ′ from the upper side. It is configured to have a five-stage filtration means (50).

In the first stage condensation collecting means 20, the smoke inlet pipe 21 connected to the smoke hood pipe 1 is installed in the horizontal direction on the dust collecting space part 12.

In addition, the lower boundary member 25 in which several large smoke passing holes 26 are drilled is fixed to the lower side of the smoke inlet pipe 21.

Therefore, the first stage condensation collecting means 20 is a state in which dust smoke is discharged to the tube end exit hole 24 when the dust smoke from the smoke hood tube (1) enters the smoke inlet tube (21), at this time the tube end outlet Since the ball 24 is close to the inner surface of the body member 11, the dust smoke hits the inner surface of the body member 11, thereby making dust such as greasy dust contained in the dust smoke (hereinafter referred to as "oil dust"). It sticks to the inner surface of the body member 11 and becomes condensed, and the condensed oil dust flows downward.

In addition, since the tube end exit hole 24 is close to the inner surface of the body member 11, the dust smoke cannot be quickly exhausted from the inner tube portion 22, and at the same time, since the small holes 23 are drilled, the inner tube portion 22 is opened. The dust smoke does not escape quickly and stays in the interior 22 for a while, so that the oil dust in the dust smoke is condensed inside the smoke inlet pipe 21 and flows down. Is dropped to the lower boundary member 25 through the small hole 23 and the tube end exit hole 24 on the lower side to fall through the smoke passing hole 26 to the second stage dust collecting means (30).

On the other hand, the smoke inlet pipe 21 is installed by adding or subtracting the diameter according to the amount of dust smoke flowing through the smoke hood pipe (1).

The second stage filter dust collecting means 30, the non-woven filter is installed so as to be fitted to the guide support member 31 of both sides which are fixed at equal intervals to the inner surface of the body member 11 below the first stage condensing dust collecting means (20). 32 and the sintered metal filter 33 and the nonwoven fabric compression filter 34 are configured to be one set filter portion 35.

In the sintered metal filter 33, the screen sieve 33a, the sintered metal sieve member 33b, and the screen sieve 33c are, for example, thin sheets of wet paper thickness, and the screen sieves 33d, 33e have, for example, book cover thicknesses. It is preferable that the thickness is 5 ply by adopting a thin thickness, but in some cases, not only a thicker thickness may be employed but also two sintered metal catching members 33b may be employed. ) Is already known filter material, so a detailed description thereof will be omitted and only the functions and roles according to the present invention will be described.

 Therefore, when the mouth is blown against the sintered metal filter 33, air passes.

Therefore, the dust smoke passes through the sintered metal filter 33. At this time, by passing through the sintered metal filter member 33b formed by sintering the stainless particles, fine dust is filtered out, and the oil component, which is a fluid component, passes and flows down.

Since the sintered metal filter 33 is relatively expensive, the filter taking out door 13 is regularly opened, taken out and washed, and then reinserted into both guide support members 31 for reuse. In Fig. 8, reference numeral 15 denotes a hinge and reference numeral 16 denotes a door hanger.

The nonwoven fabric compression filter 34 has a perforated plate body 34b having a plurality of holes 34b 'formed on and under the compressed nonwoven fabric member 34a formed by compressing the nonwoven fabric as shown in FIGS. 5 and 6. As a result, the oil flows down in the process of passing the dust smoke, and the fine dust is filtered by the compressed nonwoven fabric member 34a.

Since the cleaning or replacement of the nonwoven fabric compression filter 34 is the same as the nonwoven fabric filter 32 described above, the description thereof will be omitted.

Therefore, large and small dust or fine dust is filtered in the course of passing the one-set filter unit 35, which is operated as described above, and the oil is condensed and flows down. As one set filter unit 35 is installed in a plurality of layers, oil is condensed and flowed down from the dust smoke, and dust condensed with the dust smoke and oil is filtered.

2, 3 and 8, the three-stage condensation collecting means 40 is an upper partition plate member fixed to cross the dust collecting space portion 12 in the transverse direction below the two-stage collecting dust means ( 41) and the lower partition plate member 42 is configured to form a flow space portion 43 therebetween.

In addition, one side of the upper partition plate member 41 is fixed to the vertical inlet pipe 45 to allow the dust smoke passing through the second stage dust collecting means 30 into the flow space portion 43, the lower partition wall One side of the plate member 42 is fixedly installed a vertical exhaust pipe 47 for discharging dust smoke of the circulating space portion 43 to the bottom.

Therefore, the dust smoke flowing into the flow space 43 has a flow discharged upward from the vertical exhaust pipe 47 above the vertical inlet pipe 45 as shown by the arrow in FIG. It is supposed to have.

In addition, the vertical inlet pipe 45 and the vertical exhaust pipe 47 through the smoke hole 44 of the upper partition plate member 41 is configured so that each of the smoke holes (44, 46) only through the outer peripheral portion of the half, respectively. Inflowing dust smoke hits the inner surface of the body member 11 so that oil is condensed and flows down, and the smoke hole 46 of the vertical exhaust pipe 47 exhausts dust smoke in the corner of the return space portion 43. By doing so, the role of the dust smoke that does not escape from the flow space portion 43 does not exist.

In addition, the dust smoke staying in the flow space portion 43 is configured to be swirled by a whirlwind caused by the wind blown by the blowing fan 48.

Therefore, the dust dust flowing back hits the body member 11 and the upper and lower partition plate members 41 and 42 and the vertical inlet pipe 45 and the vertical exhaust pipe 47 so that the oil dust contained in the dust smoke is contained. They stick to their surface, congeal, flow down, and separate.

The blower fan 48 may be installed in the flow space 43, but may be installed in the filter takeout door 13 for maintenance. The illustration of the control panel for operating the blower fan 38 is omitted.
