Abstract

PURPOSE:To improve removing efficiency for fats and oils by installing an oil eliminator having twisted blades like a screw in a passage of waste smoke arranging the direction of the shaft perpendicularly to the passage of the oil smoke. CONSTITUTION:Oil smoke (a) is introduced into a hood 11 from an opening 13 and is reversed by a deflecting baffle plate 5, and then allowed to pass through an oil eliminator 4, moved around a shaft of twisted blades 2 like a screw to cause spin revolution. Oil (or fat) contained in the smoke is flung awaw and is allowed to collide against a wall of the vessel 3. The oil smoke is allowed to collide against an inclined bottom surface 12, passed between deflecting plates 20, 21, and discharged through a fire-preventing damper device 9 and a duct to the rooftop.

Description

[Detailed Description of the Invention] [Technical Field] The present invention is mainly installed on a heat cooking appliance in a commercial kitchen, and introduces oil smoke containing oil and fat to separate and recover fats and oils in the oil smoke from the oil smoke. [Background Art] Conventionally, an inverted baffle type oil separation and recovery device as shown in FIG. 1 has been known. As shown in FIG. The centrifugal force of the time causes the oil and fat in the oil smoke (A) to collide with the baffle wall (6) and separate and remove it, and in the reversing baffle method, it is continuously (intermittently) Even if the flue gas passage (0) is made to meander in a zigzag manner for the purpose of reversing, it will result in an unnecessary increase in pressure loss. There was a problem that the area was small and the oil removal efficiency was low due to the length of the smoke exhaust path.Furthermore, in the conventional example, the inside of the smoke exhaust path (0) was opened continuously over the entire width. Since there was no obstacle to smoke exhaust, the oil smoke (-1') that entered the smoke exhaust path (0) created a slight speed difference from the center in the width direction to both wings, and Oil smoke (-1') concentrates and easily passes through, and centrifugal force is attenuated on both wings, so oil 09 collides and aggregates in the center of the baffle wall (6) as shown in Figure 3. L is the width of the baffle wall, W' is the thickness of the oil, f
J wear width), both wing parts are not useful for capturing oil and fat, and are not able to perform their function.

[Purpose of [Hayu]]

The present invention was made in view of the drawbacks of the conventional examples described above, and its purpose is to spin the oil smoke containing oil and fat by passing the oil smoke through an oil eliminator constituted by twisted blades. The oil smoke is spread over the entire width of the smoke exhaust passage, and the centrifugal force caused by this spinning motion causes the oil and fat in the oil smoke to be baffled and separated as it passes through the oil eliminator, making it possible to apply centrifugal force continuously without any breaks. [Disclosure of the Invention] The oil separation and recovery device of the present invention has an oil eliminator that can improve oil removal efficiency per flue flue length. -(4)
and install an oil eliminator (4) in the smoke exhaust passage (0) provided in the main body housing (7) so that the axial direction of the twisted vane (2) is perpendicular to the flow direction of the oil smoke (A).
This is how the above objective was achieved.

The present invention will be explained in detail below with reference to the accompanying drawings. (7) is the main body housing with an open top and front surface, and the top opening (8)
A fire prevention tampering device (9) is mounted on the front opening (10), and a hood (+1) extends forward from the top and both side edges of the front opening (10). Main body housing (7)
The lower front surface of the hood (U) is formed with a sloped bottom surface α that slopes diagonally upward toward the front, and the opening (13) of the hood (U)
The opening is obliquely inclined so that the inclined bottom surface θ is in contact with the road surface. θ is a middle plate that is retracted slightly deeper than the front opening (10) of the main body housing (7) and is provided vertically, and the middle plate (14) has an open opening, and the middle plate 04)
A baffle wall (6) extends diagonally upward from the upper end toward the upper level of the front opening (lO).

(4) is an oil eliminator that is integrally formed by arranging a plurality of screw blades (2) horizontally in a row, and the deflection baffle plate (5) extends diagonally upward from the front part on the oil smoke inlet side toward the back. ) is extended, and the lower surface on the oil smoke outlet side is narrowed slightly to form locking portions 05) at the front and rear. On the other hand, the lower end of the middle plate θ4) has a locked piece θG bent toward the front.
) is provided at the upper end of the inclined bottom surface (I2).
7) is installed upright, the oil trapping unit (4) is delivered through the opening θ (support) of the hood (Il), and the back side is installed on the middle plate 04.
), and the front and rear locking parts θ5) are brought into contact with the locked piece (
The deflection baffle plate (5) faces the baffle wall (6). The oil and fat trapping unit (4) protrudes from the bottom and the oil smoke outlet side faces the inclined bottom surface (1).

The upper surface of the fire prevention tambour device (9) is connected to a tact (not shown) in the ceiling, and when it is forcibly discharged by an exhaust fan (not shown), the oil WJ containing oil smoke is removed. , (A) are forcefully introduced into the hood (11) through the opening (13). The introduced oil smoke (A) goes around the tip of the deflection baffle plate (6) and is forcibly reversed, and at this time, the oil smoke (coarse particles and fine dust of zero-year-old oil in the treetops collide with the baffle wall Ie+ due to inertia) Moreover, since the oil eliminator (4) is located directly below the oil smoke (1') that has been reversed by the deflection baffle plate (5), the oil smoke (-0) is slightly decelerated here. Since the oil and fat is spun and spread almost completely in the width direction, the attached oil and fat spreads in the width direction of the baffle wall (6) by a width W as shown in Fig. 10, and adheres almost uniformly. , oil smoke (-11) passes through the oil eliminator (4).

As shown in Figure 6, the oil eliminator (4) consists of one or more twisted blades (2) twisted into a screw shape in a stainless steel container (3) so that the axial direction is parallel to the width direction. However, if multiple twisted blades (2) are delivered, one with a right-handed twist and one with a left-handed twist may be placed side by side as shown in Figure 7. You may use only those. In addition, as shown in Fig. 8, there are a right twist element (1a) and a left twist element (1b).
) can also be used. It is also possible to use a torsion blade (2) formed continuously and coaxially.

As the material for this screw blade (2), stainless steel, ceramic, heat-resistant synthetic resin, etc. are used. However,
The oil smoke (A) that has flowed into the oil eliminator (4) collides with the twisting blade (2) and spins around 611 of the twisting blade (2) as shown in Figure 5. It flows along the axial direction of the twisted vane (2), thereby spreading the oil to the full width of the oil eliminator (4), and at the same time, the centrifugal force at this time shakes off the oil and fat and causes it to flow against the wall of the container (3). The oil and fat components collide with each other and are separated due to the collision between the oil and fat components due to the turbulent flow caused by the flow of the oil smoke (a) being turned approximately 90 degrees. are efficiently removed.

The oil eliminator (4) collides with the oil smoke (-0 is the inclined bottom surface 02 of the main body housing (7)) and is reversed upward, and the centrifugal force at the time of reversal causes the oil and fat (J
layer ~.

Further, deflection plates 1221 bent in a dogleg shape in cross section are alternately provided on the front surface of the back plate (I9) and above the middle plate (14) of the main body housing (7), and these deflection plates 1221 are bent in a dogleg shape in cross section. ``The rising oil smoke (A) is made to meander and become baffled by centrifugal force.

In this way, the fats and oils () are divided into I! The exhaust gas (a) from which fL has been removed passes through the fireproof tambour device (9) and is discharged outdoors from the tact.

The fire prevention tamper device (9) is equipped with a plurality of shutter blades that can be opened and closed, and an automatic closing mechanism is installed on the outside. ) When a temperature sensor such as a thermistor or thermocouple projecting toward the camera detects a preset detection temperature, the electromagnetic device in the automatic closing device 41 is activated and the shutter blade El is sealed. It is a trap to prevent the spread of fire. In addition, a temperature sensor e271 such as a thermistor is installed on the top of the hood (0), and when it detects an abnormal temperature, it closes the shutter blade Co., Ltd. 1 and activates the fire extinguishing nozzle under the main body housing (7). (c) Inject fire extinguishing liquid to the lower heat cooking equipment.

29) is a cleaning nozzle that jets out a cleaning solution (g) such as hot water containing detergent at a certain time. It can prevent oil and fat from sticking, and it can be easily cleaned without the need for manpower. Also, even when the temperature rises abnormally, cleaning fluid (or digestive fluid) can be spouted from here and used for digestion. The waste water after cleaning is discharged to the outside through a drain pipe at the bottom of the main body housing (7).

The one shown in Fig. 9 is another example of the present invention, in which two types of torsion vanes (2) of different diameters, large and small, are arranged in upper and lower stages to form an oil eliminator (4). ,oil!
(A) is rotated twice by a twisting blade (2) to separate oil and fat.

〔Effect of the invention〕

Kihatsu E! 14 is formed as described above, the oil smoke that has flowed into the oil eliminator collides with the torsion vane, is spun around the rotation of its axis, and moves in the axial direction, causing the oil smoke to flow into the υF flue. It spreads to its full width, making it possible to effectively utilize both corners of the smoke exhaust duct.Moreover, the oil smoke spins, and its centrifugal force shakes off the oil and fat, separating it and removing it. It has the advantage of high oil and fat content per length and the ability to make the device more compact.
