に粘度が増大し遂にはガラス状に固化するような物質、
即ち融点を持たない樹脂状物質の造粒方法に関する。[Detailed description of the invention] A substance whose viscosity increases and finally solidifies into a glass-like state,
That is, the present invention relates to a method for granulating a resin-like substance that does not have a melting point.

法に関する。More specifically, the present invention relates to a simple granulation method that can be widely used for resinous substances such as alkylphenol formalin resins and alkylphenol sulfide resins, which are used as rubber additives and are produced in a wide variety of products in relatively small quantities.

理物質の物性によっては正常に造粒できない場合もある
。Conventionally, methods for granulating resinous substances include (1) spraying a high-temperature molten liquid into a space and cooling and solidifying the droplets before they fall to obtain granules; (2) using the molten liquid as a cooling liquid. (3) Separate the molten liquid drop by drop onto a cooling belt conveyor and drip it, then cool and solidify it to obtain granules. There are ways to get things. However, all of these methods require a large amount of or complicated equipment, and depending on the physical properties of the material to be treated, normal granulation may not be possible.

なる。That is, in method (1), it is preferable for the viscosity of the melt to be as low as possible for spraying, but if the temperature is raised for this purpose, decomposition or alteration may occur depending on the substance to be treated, and good spray conditions may not be achieved. There is. Furthermore, this method requires a huge amount of space for cooling and solidification, and therefore the equipment is large and expensive. Next, in method (2), water sound is normally used as a cooling liquid, but if the substance to be treated is dissolved in water or deteriorated by water, a separate cooling liquid is required, and further separation from the cooling liquid or drying is required. Additional steps such as these are required, which also increases energy consumption. Furthermore, method (3) seems to be relatively simple, but it produces granular particles.
Since it is necessary to drop each individual separately, a device with a complicated structure is required for the dropping part, and it is difficult to increase processing efficiency. Therefore, the device also becomes large and expensive.

している。Due to the above situation, when producing a wide variety of products in relatively small quantities, such as resinous substances currently used as rubber additives, it is almost impossible to granulate the material, instead grinding the solidified material into chunks. It is available as a powder. However, when obtaining such a powder, it requires manual labor to remove the solidified mass, resulting in poor productivity, and on the user side, such powder has the disadvantage that it has poor flow and is difficult to scatter.
本発明は以上のような実状に立脚し、それら欠点を改良
すべ〈発明されたものであり、冷却によってガラス状に
固化するあらゆる樹脂状物質に適用でき、しかも少量多
品種生産でも品種切替利用が容易にできる安価な装置し
か必要としない簡便な造粒方法を提供することをその目
的とするものである。The present invention is based on the above-mentioned circumstances and has been invented to improve these shortcomings.It can be applied to any resinous substance that solidifies into a glass-like state by cooling, and can also be used to switch types even in small-lot, high-mix production. The object is to provide a simple granulation method that requires only inexpensive equipment.
しかして、本発明者らは、上記の如き目的に対処し・こ

高温では液状であるが、冷却するとガラス状に固化する
、いわゆる融点をもたない樹脂状物質に、その物質の軟

に造粒できることを見出した。In order to meet and meet the above objectives, the inventors of the present invention conducted various studies, and as a result, they found that the so-called melting point, which is liquid at high temperatures, but solidifies into glass when cooled. It has been found that granulation can be easily achieved by giving a resin-like substance that does not have a granule a uniform shape at a temperature below the softening point of the substance.
そこで、更に上記検討に続き、上記の造粒をより簡便に

に至った。Therefore, following on from the above studies, we further investigated a method that could more easily carry out the above granulation, and found that the material to be treated is spread out in a molten state in the form of multiple strings, and this is softened. to a temperature below the glass transition point and above the glass transition point,
That is, by cooling to a temperature that allows plastic deformation and cutting these multiple string-like expanded pieces at a time to a certain length, it is possible to make granules of a certain shape. , the bath melt of the processed material is transferred onto a coolable belt conveyor.
This can be easily achieved by cutting the string-like material as multiple liquid streams.Another way to cut the string-like material is to use an impeller, which is rotated so that its tip speed is equal to the running speed of the belt. ! We have come to the conclusion that a simple method of pressing ``lx'' onto the string-like developed material is sufficient.

とも判明した。In particular, the cutting of the string-like developed material by the impeller is a so-called forming operation in which a blade shape is simply pressed, and the cutting point is not a complete cut, but a continuous shape with a slight thickness remaining. However, the string-like developed product formed in this way becomes friable when cooled to a temperature below the glass transition point, and the cut point, which has only a small thickness, can easily be shattered by a slight impact. It was also found that granules with a certain shape can be formed.

A resin-like substance that solidifies into glass is divided into multiple liquid streams in the form of a molten liquid, which are then flowed down onto a belt conveyor equipped with a cooling means, where they are spread as they run.

粒方法を特徴とするものである。When the substance is cooled to a temperature below its softening point and above its glass transition point, a rotating impeller is pushed against the substance so that the tip speed is equal to the traveling speed of the healdconhair to form a vane. After the material is further cooled to a temperature below the glass transition point of the material, it falls off the belt conveyor and collides with a collision plate installed on the way down, crushing each cut surface. The granulation method is characterized by a granulation method comprising:

It will finally solidify into glass! IJ is a pipe that feeds a molten liquid of a resinous substance that does not have a melting point and divides it into multiple liquid streams (a conveyor belt with a cooling means placed at the bottom after passing through 21k; the figure shows a cooling water inlet ( The belt conveyor 00) has a cooling water outlet (9) and a cooling water outlet (9), and flows down as a plurality of liquid streams onto the conveyor belt section, which is equipped with a means for injecting cooling onto the transfer surface of the conveyor belt.
As the belt conveyor 00) runs, the liquid stream is cooled while being spread out into a plurality of strings (not shown), and then as the belt conveyor 00) runs, the temperature of the string-like spread material (3) increases. Below the softening point of the substance and above the glass transition point.

The string-like developed material (3) is brought into contact with the impeller (4) which is rotating at a tip speed that is equal to the running speed of the belt conveyor CIO+, which is disposed on the filter. A cut surface is formed on the string-like developed material by pressing it against the impeller (4), and the string-like developed material (5) is further cooled until the temperature reaches the glass transition point. When the temperature reaches the following level, the belt will fall off from the end of the conveyor 00), and by colliding with the collision plate (6) installed in the middle of falling, the string-like developed object will be finally formed on each cut surface. The granules (7) are completely crushed into one piece.

This belt conveyor (00) equipped with a cooling means is made by spraying cooling water on the back side of a common steel belt.
A so-called belt flaker for cooling is used, but of course the present invention is not limited to such a belt flaker. For example, is it possible to use a rubber belt conveyor as well? Any device that allows frK to flow uniformly and can be cooled can be used.

流が一定であれば送入王によって変えることができる。In addition, as a method for dividing the molten resinous substance into a plurality of liquid streams and flowing them down, a plurality of holes of a constant diameter are provided at the bottom of a pipe installed horizontally on a belt conveyor, and the pipe is Molten liquid? You can use the simple method of sending it. The temperature of the molten liquid at this time may be any temperature that allows the liquid to flow, and does not require a particularly high temperature. Further, the diameter of the hole provided in the piping is related to the thickness of the string-like developed product and can be freely selected depending on the desired thickness. Furthermore, the outflow speed of the melt flowing out of this hole can be varied by the feed valve if the flow is constant.

If the belt speed is too low for the melt to flow down, the string-like developed product tends to become meandering, and if the belt conveyor is the opposite, the falling melt is pulled by the belt conveyor, and the thickness of the string-like developed product tends to be uneven. .
従って通常、上記両速度は略等速である。Therefore, normally, the above-mentioned two speeds are substantially constant.

期して回転させる動力伝達装置を持つのが望ましい。FIG. 2 is a detailed view of the impeller (4), which is disposed at the upper part of the belt conveyor in the implementation process and is used to cut the resinous material spread out in the form of a string. As shown above, plates (4b) of a constant width and length are welded to the outer periphery of the cylinder (4a) at equal intervals. In this case, the tips of the blades are desirably finished at an acute angle to facilitate cutting, but there is no particular need for hardening treatment such as quenching. This is because the impeller only has to perform the role of making an incision where the resinous material is in a soft state, preventing plastic deformation. However, the setting position of this impeller must be in a range where the temperature of the string-shaped developed material is below the softening point of the material and above the glass transition point. Preferably, the temperature is just around the midpoint between the softening point and the glass transition point. If the impeller is placed at a temperature higher than the softening point, the string-like developed product will still have fluidity and will not be able to adhere to the impeller or maintain its shape even if a cut surface is applied. In addition, when a complete set of impellers is placed at a temperature below the glass transition point, the string-like developed material will be completely solidified, and as mentioned above, crushing will occur by pressing the impeller, resulting in granules of a certain shape. It becomes impossible to mold. Note that the rotation of the impeller can also be given by contact with the belt conveyor, and this method is a simple method that automatically makes the tip speed of the impeller and the running speed of the belt conveyor equal, but it is not preferable. It is desirable to have a power transmission device that rotates the impeller in synchronization with the running of the belt conveyor.

It is only necessary to apply a pressing pressure that is sufficient to give a cut surface to the string-shaped developed product, and the durability of the belt surface of the belt conveyor and the tip of the blade of the impeller is improved.

When it fell off, there were several to ten or more granules separated by each cut surface.

As a method of crushing the particles one by one, an extremely simple method is used in which a collision plate (6) is provided during the falling speed of the particles. The mounting position of the collision plate should be set at a height sufficient to crush the granules one by one (this varies depending on the material to be treated, but
~50 crn is sufficient), and care must be taken to ensure that the particulates collided and crushed do not accumulate and fall at an inclination, but other shapes and installations are required. There are no restrictions on the method.

。The method of the present invention has been described in detail above, but according to the method of the present invention, a belt conveyor that can be cooled, a pipe provided with a plurality of holes through which a molten liquid of a resinous substance flows, and a tip speed that is Granulation is possible if there is an impeller that rotates at the same speed as the belt conveyor and a collision plate that is installed so that a series of falling granules collide with each other, and the resulting granules are constant. It has a uniform shape and size, and does not require any extra steps such as drying after granulation. In addition, there is no part of the equipment other than the piping through which the molten resinous material flows down onto a conveyor equipped with a cooling means, where the resinous material remains in liquid form, and therefore the piping described above must be replaced or replaced. It has the feature that it can be easily used for granulation of other resinous substances by simply washing and replacing it.

造粒方法。l At high temperatures, it becomes a molten liquid, but as it cools, its viscosity gradually increases and it finally solidifies into a glass-like state.In the operation of cooling and solidifying a molten liquid of a resinous substance, a plurality of molten liquids are placed on a belt conveyor equipped with a cooling means. The liquid is divided into two liquid streams and cooled as they are spread out into multiple strings as they run on a belt conveyor, and the temperature of the string-like spread is below the softening point of the substance and above the glass transition point. In a temperature range of The string-like developed material is broken into its cut surfaces by falling off the belt conveyor after the temperature reaches a temperature below the glass transition point and colliding with a collision plate provided on the way of falling. A method for granulating resinous substances.
