Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soap manufacturing apparatus for manufacturing soap from waste edible oil from household as a raw material, which is suitable for use by local women's associations, etc. Is. If the used cooking oil used for cooking oil is discarded as it is in a river, it will lead to water pollution in the river, and even if it is incinerated, it will generate high heat and damage the furnace. Encouraged to do. In response to this, local women's associations and other organizations are producing soap using this as a part of their local activities.

[0002]

2. Description of the Related Art Soap can be produced by adding caustic soda or soda ash dissolved in water to oil and fat and heating it. In addition, it is a method of reacting while stirring with a rice scoop, etc., but the content expands during the reaction and overflows from the kettle and scatters, which is dangerous.
There is also a problem that it is difficult to form a uniform product because the stirring is not sufficiently performed and oil remains.

For this reason, a manufacturing apparatus using a reaction vessel as shown in FIG. 8 may be used. That is, the stirring blade D driven by the motor C supported by the frame B is thrust into the reaction kettle A, and the burner E for heating is placed under the reaction kettle A. As a result, the raw materials and additives were put in the reaction kettle A and heated while being stirred by the stirring blade D. In addition, considering the convenience of taking out and cleaning the contents,
The reaction vessel A is attached to be tiltable around a horizontal support shaft G supported by a frame F.

[0004]

However, this device still has the following drawbacks. That is, the opening of the reaction kettle cannot be narrowed because the stirring bar is attached and detached, and the risk of scattering remains. Since the stirring blade is thrust into the reaction kettle, it is not possible to effectively heat the tilting of the reaction kettle. Since only the lower part of the reaction kettle is partially heated, sufficient and homogeneous heating cannot be obtained, and charring tends to occur. Grinding is not sufficient with the stirring blades, and oil balls with a diameter of several tens of millimeters are formed, and unreacted oil tends to remain. Moreover, it has to be removed when the reactor is turned over to remove the finished product. Even if it is cleaned after use, it is difficult to attach the stirring blade again and add water. The present invention solves such a problem, and is a device that can be easily used by anyone, and is capable of producing high-quality and uniform soap safely, in a short time, without much labor. Is.

[0005]

Under the above problems, the present invention is mounted on a tilting frame which is tiltable around a horizontal support shaft and a tilting frame which is forcibly rotated in a plane including the horizontal support shaft. The present invention provides a small soap manufacturing apparatus using waste cooking oil as a raw material, which comprises a reaction kettle in which a crushing grid is attached, and a burner attached to a tilting frame with the crater facing the reaction kettle.

[0006]

By the above means, that is, since the reaction vessel is heated while being tilted and forcibly rotated, stirring of the raw materials and the additives contained therein,
It excels in mixing and crushing. In particular, since the content of the lattice body provided in the reaction kettle is pulverized to below the mesh, the pulverization effect is outstanding. Further, since the burner is attached to the tilting frame, the relative positional relationship between the two remains unchanged even if the attitude of the reaction vessel changes, and there is no heating unevenness.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a partial sectional front view of a soap manufacturing apparatus showing an embodiment of the present invention, FIG. 2 is a side view, and FIG. 3 is a plan view. Frame 1
2. It comprises a reaction kettle 14 and a (gas) burner 16. The base frame 10 is composed of a base 20 having casters 18 for movement attached to its bottom surface, and base columns 22 standing upright on both left and right sides of the base 20.

The tilting frame 12 has a U-shape in which horizontal support shafts 24 project on the left and right sides, and the horizontal support shafts 24 are rotatably supported by the base column 22.
As a result, the tilting frame 12 can be tilted in a vertical plane about the horizontal support shaft 24, but a lever 26 for tilting is attached to the tilting frame 12 in consideration of the convenience at this time.

The reaction kettle 14 is a cylindrical body having an opening at the top narrowed and a collar 28 formed near the top, and has a support shaft perpendicular to the horizontal support shaft 24 on the bottom surface. 30 is provided, and this support shaft 30 is used for the tilting frame 12
On the other hand, it is rotatably supported by a bearing 32. The reason why the mouth of the reaction kettle 14 can be narrowed is that a sufficient stirring effect can be obtained without thrusting and stirring the substance from the opening as will be described later. To be prevented.

Further, the reaction vessel 14 is forcibly rotated in a plane including the horizontal support shaft 24 of the tilting frame 12. Therefore, the gear 34 is attached to the entire lower surface of the brim 28, and the pinion 36 that meshes with the gear 34 is attached.
Of the base pillar 2 through the horizontal support shaft 24.
2 is extended to the outside, and a pulley 38 is fixedly fitted to this, and the pulley 38 is driven by a motor 42 via a belt 40. The gear 34 and the pinion 36 may be friction wheels.

As a result, when the motor 42 is driven, the force is transmitted from the pinion 36 to the gear 34, and the reaction kettle 1
4 rotates about the support shaft 30. The motor 42 employs a motor capable of rotating in the forward and reverse directions.
It is desirable to be able to perform normal rotation and reverse rotation as required. or,
The transmission mechanism such as the belt 40 is covered with a cover 44 for safety. As described above, by allowing the reaction kettle 14 to be tilted and rotated, uniform heating can be performed, and at the same time, it is possible to shorten the heating time and save fuel consumption.

In addition, one or a plurality of grids 46 are attached to the inner peripheral wall of the reaction vessel 14 in a state of standing up inward. The lattice body 46 is for crushing the contents, stirring and mixing the contents, and has a wire diameter of 2
It is made into a mesh shape by using a wire rod of ~ 6 mm. The mesh size is preferably about 10 mm, and when the reaction kettle 14 is rotated and stirred and mixed, the content is the lattice 4
It permeates through 6 and is crushed to below this mesh.

The rocker frame 12 is provided with a burner 16 with its crater facing the reaction kettle 14 and having a sufficient wind protection structure, and a hose 4 for guiding gas to the crater.
8 is extended outside the apparatus. Since it is desirable that the burner 16 hit the bottom of the reaction kettle 14 and the fire as much as possible, the burner 16 is provided at the position of the inclined portion below the reaction kettle 14. When the burner 16 is provided at this position, the support shaft 30 provided at the bottom of the reaction kettle 14 approaches the burner 16, so that the temperature of the reaction kettle 14 is transmitted to the bearing 32 and the like via the heat insulating material 50. Keep it difficult. As a result, the bearing 32 and the tilting frame 12 do not have to be heat-resistant, and there is an advantage that the cost is reduced.

A container 52, which can store caustic soda and soda ash additives, is installed above the reaction kettle 14 so as to be able to come into contact with and separate from the reaction kettle 14. The reason why the position of the container 52 can be changed is that the additive can be safely put into the container 52 from a distant position while the reaction kettle 14 is being rotated and heated, and the opening position of the reaction kettle 14 can be tilted. This is to ensure that the additive is added to this even if the value changes, and to prevent it from interfering with the work when not in use. The container 52 includes a first container 54 for soda ash and a second container 56 for caustic soda.
An arm 58 that is fixed to the upper end of 2 and rotates in a horizontal plane
It has a funnel-shaped discharge port 60 formed on its lower surface. The latter is supported by a sub-arm 62 or the like which is rotatable in a plane vertical to the arm 58, a cock 64 for adjusting the injection amount is provided at the outlet, and a flexible pipe 66 for injection is continuous from this. .

As described above, soaps can be produced by putting fats and oils such as waste edible oil in the reaction kettle 14 and adding reactants such as caustic soda in several times while heating them. In the case where soap is produced by using 10 liters of oil and fat (a little less than 20 kg of soap can be produced), a concrete production procedure will be outlined.

First, after putting all the fats and oils in the reaction kettle 14 and igniting the burner 16 and heating to about 70 ° C., 250 g of caustic soda was dissolved in 1.4 L of water to prepare the second solution described above. The container 56 is gradually poured into the reaction kettle 15 over about 10 minutes. In this case, the temperature rises further, but in order to obtain a uniform reaction, it is necessary to take care so that the temperature does not exceed 120 ° C. Reaction is 40-50
This lasts for about a minute, and during this period, the content expands about 3 times in volume including the generated gas. In order to accelerate this reaction, the reaction vessel 14 is rotated and the lever 26 is appropriately operated to tilt it. This tilting operation is important for stirring to accelerate the reaction of the contents, and is just like tilting and rotating the tank when kneading the concrete mixer.

Once the above reaction has subsided, 30 g of the second solution prepared by dissolving 500 g of caustic soda in 1.5 L of water is added.
Pour over about a minute. The reaction is activated again, but at this time also, it is important to control the temperature so that the temperature does not exceed 120 ° C. If the above reactions subside, caustic soda 11
A third solution prepared by dissolving 50 g in 1.5 L of water is poured again over about 30 minutes. When the third solution is poured, the temperature is gradually lowered to about 70 ° C. During this time, as the reaction progresses, the contents change from a candy-colored liquid to a grated apple, and finally a miso-like substance. After about 2 hours from the start of the reaction,
It loses water and becomes brown sugar.

When it becomes brown sugar-like, 6.25 kg of soda ash is put into the first container 54, and this is poured over about 10 minutes. Also at this time, the reaction kettle 14 is continuously tilted and rotated so that the soda ash is mixed well with the contents.
At this time, a small amount of fragrance or the like may be added. Further, when the mixture is stirred and pulverized for about 20 minutes, soap is produced, so that the lever 26 is operated to invert the mouth of the reaction kettle 14 so as to face downward and take it out.

At this time, the front surface of the base 20 is cut out so as to have a U-shape in plan view so that the receiving container and the like can easily enter under the reaction kettle 14 (see FIG. 3). This is dried in the sun for about 2 days, and crushed with a crusher to obtain powder soap. In addition to the above, in order to prevent the contents of the reaction kettle 14 from scattering and being applied to the operator during the above operation, the reaction kettle 14
A transparent shield cover 68 that covers the tip of the container may be attached to the container 52 or the like (see FIG. 2). Further, it is desired to clean the inside of the reaction kettle 14 after use, but this can be easily done by putting water inside and rotating.

FIG. 4 is a partially sectional front view of a soap producing apparatus showing another embodiment of the present invention, and FIG. 5 is a side view. In this embodiment, the tilting of the tilting frame 12 is performed by the handle 70. In addition, the positioning is performed by stepping operation. That is, this is due to the positioning drum 72 fixedly fitted to the horizontal support shaft 24 of the tilting frame 12 and the lock rod 74 that acts on the positioning drum 72 from below. A plurality of notches 76 corresponding to various tilting positions of the reaction kettle 14 are formed on the outer periphery of the positioning drum 72, and a lock rod 74 which is urged in and out by a spring 78 in and out of the notches 76 is provided. It is provided so as to lower when the pedal 80 is depressed. Such a handle 70 also serves as a handle when moving the device.

As described above, when the reaction kettle 14 is to be tilted, the tilting frame 12 can be freely tilted by stepping on the pedal 80 and pushing down the lock rod 74 to remove it from the notch 76. Turn to tilt it to the desired position. Then, when the foot is released from the pedal 80, the lock bar 74 enters into the notch 76 which has come to the corresponding position by the action of the spring 78, and the tilting frame 12, that is, the reaction kettle 14 is fixed at this position. On the other hand, when inverting the reaction vessel 14 when taking out the contents, the same operation may be performed. It is desirable that the tip of the lock bar 74 be tapered so that this operation can be performed smoothly.

FIG. 6 is a cross-sectional view of an essential part showing another embodiment of the reaction kettle 14. In this embodiment, a temperature sensor 82 is attached to the reaction kettle 14. That is, the reaction kettle 14
A recess 84 is formed on the bottom of the mounting shaft 86, and a mounting shaft 86 fixed to the tilting frame 12 is inserted into the recess 84 to mount the mounting shaft 86.
The reaction kettle 14 is axially supported by the bearing 88. A cavity 90 is also provided in the mounting shaft 86, and the temperature sensor 82 is accommodated in the cavity 90 (92 is a lead wire). By the way, in this case, the reaction kettle 14
If a heat insulating material 94 is inserted in the middle of the mounting shaft 86 or the mounting shaft 86, it is not necessary to use a heat-resistant bearing 88, a part of the mounting shaft 86, or the like (the price is reduced).

When such a temperature sensor 82 is used,
It becomes possible to automatically control the heating temperature of the reaction kettle 14. That is, an automatic ignition device may be attached to the burner 16, gas supply may be controlled by a solenoid valve or the like, and these operations may be performed by the temperature sensor 82. On the other hand, correspondingly, it is possible to automate the injection of additives such as caustic soda and soda ash. Specifically, the first solution to the third solution of caustic soda are respectively stored in dedicated tanks, and each can be supplied by an electromagnetic valve, and the operation is performed by a temperature sensor 82 or a timer. . In addition, a shutter that operates with a solenoid is attached to the outlet of the soda ash container,
This shutter is opened by a command from a timer or the like. By doing so, it becomes possible to fully automate the soap manufacturing apparatus.

FIG. 7 is a cross-sectional view of an essential part showing the mounting state of the lattice body 46, but it is preferable that the lattice body 46 is attached so as to be inclined with respect to the center line of the reaction vessel 14. This way
With the rotation of the reaction kettle 14, the contents are agitated while being fed in the downward slant direction, so that the effect of agitation and crushing is enhanced.
At this time, if the reaction kettle 14 is rotated forward and backward with an appropriate interval, the feeding direction of the contents becomes up and down, and the stirring and crushing effect is further enhanced.

[0025]

As described above, the present invention is as described above, that is, the reaction vessel rotates in a tilted state, and the reaction vessel is provided with a lattice, so that the heating can be performed. In addition to being highly effective, it is excellent in stirring, crushing, and mixing soap raw materials and additives. In particular, since the contents are crushed to below the mesh by the lattice, large lumps do not remain as oil balls. Further, even if the reaction kettle is tilted, the relative position with respect to the burner does not change, so that uniform heating without unevenness can be obtained. as a result,
In a shorter time than before, high-quality, uniform soap is safe,
And it can be easily manufactured.
