【発明の詳細な説明】
本発明は高粘度樹脂液圧送混合装置の洗浄方法に関Ｊる
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for cleaning a high viscosity resin liquid pumping mixing device.
高粘度樹脂液圧送混合装置（以下、「装置」と略す）と
は、高粘度の熱硬化性樹脂液と、硬化剤とを受入れ口か
ら取り入れ、それらを混合し、混合液が硬化する前に該
混合液を排出口から排出し、装置外部での使用に供する
ものである。A high-viscosity resin liquid pressure-feeding mixing device (hereinafter abbreviated as the "device") is a device that takes in a high-viscosity thermosetting resin liquid and a curing agent from a receiving port, mixes them, and mixes them before the mixed liquid is cured. The mixed liquid is discharged from the discharge port and used outside the apparatus.
従来、かかる装置内部に残溜し、ＩＩＩＪ肴する混合液
の洗浄は、第５図に示１如く、溶剤１７を用いて行なっ
ていた。Conventionally, cleaning of the mixed liquid remaining inside such an apparatus and being served has been carried out using a solvent 17 as shown in FIG. 5.
即ち、装置の使用後に装置のミキザ一部１０の始端に連

混合液１５を洗浄していた。こ− ２ −
こに、配管１１どは、ミキ１ノー一部１０？’混合した
混合液１５を、装置外部へ排出する配管である。That is, after using the device, the solvent 17 is injected by the pump 16 from the pipe 11 connected to the starting end of the mixer part 10 of the device, and the mixed liquid 15 remaining inside the mixer part 10 and the pipe 11 is cleaned. Was. 2 - Here, what about piping 11? Miki 1 no part 10? 'This is a pipe that discharges the mixed liquid 15 to the outside of the apparatus.
なお、図において、配管８は、主剤てパある熱硬化性樹
脂液１を、装置のミキサ一部１０の始端へ導く配管であ
り、配管９は、硬化剤３を同じくミキ１ノ一部１０の始
端へ導く配管である。In the figure, piping 8 is a piping that guides the thermosetting resin liquid 1 containing the main agent to the starting end of the mixer part 10 of the device, and piping 9 is a piping that guides the curing agent 3 to the mixing part 10. This is the piping that leads to the starting end of the pipe.
しかし、従来の、溶剤１７を用いた洗浄方法【よ、以下
のような欠点を有しでいた。However, the conventional cleaning method using a solvent 17 had the following drawbacks.
第１に、溶剤１７の洗浄能ツノは低く、洗浄に長時ｊム
１を要した。そのため、装置の断続的使用に際しては、
その都度装置を洗浄する必要があるにもかかわらず、そ
の要求に充分答えられず、装置の使用効率を下げていた
。First, the cleaning ability of the solvent 17 was low, and cleaning took a long time. Therefore, when using the device intermittently,
Although it is necessary to clean the equipment each time, this request cannot be adequately met, reducing the efficiency of equipment usage.
第２に、同じく溶剤１７の洗浄能力が低いことに起因し
、装置のミキ１ノ一部１０の内部及び配管１１の内部に
大量に混合液１５が剛着している場合、それを除去しき
れず、しばしば残溜混合液が装置内部で硬化し、装置を
詰まらける事態が発生した。ぞのため、装置の分解、整
１粕に崗重な片間と費用を関した。Secondly, due to the low cleaning ability of the solvent 17, if a large amount of the mixed liquid 15 adheres to the inside of the mixer 1 part 10 and the inside of the piping 11 of the device, it is difficult to remove it. Instead, the residual mixed liquid often hardened inside the device, causing the device to become clogged. Therefore, we spent a lot of time and money disassembling the equipment and cleaning it up.

本発明は、従来の洗浄方法のかかる欠点に鑑み案出され
たものであり、短時間に装置の内部を洗浄することがで
き、かつ、確実に装置内部の混合液を除去できる、洗浄
方法を提供するものである。-31 The present invention was devised in view of the drawbacks of conventional cleaning methods, and it is possible to clean the inside of the device in a short time, and to reliably remove the mixed liquid inside the device. A cleaning method is provided.
即ち、本発明にかかる洗浄方法とは、装置の始端から押
出し用樹脂液１２を圧入し、装置内部に残溜している混
合液１５を、該押出し用樹脂液１２にＪ、す、ところて
ん式に押出し、ＩＩＩ内部の混合液１５を一掃口んとづ
るものである。That is, the cleaning method according to the present invention involves pressurizing the resin liquid 12 for extrusion from the starting end of the apparatus, and adding the mixed liquid 15 remaining inside the apparatus to the resin liquid 12 for extrusion. The liquid mixture 15 inside III is extruded into the mouth.
したがって、押出し用樹脂液１２の粘度は、主剤である
熱硬化性樹脂液１の粘度と少なくとも同程度、あるいは
、ざらに高粘度のものが望ましい。Therefore, the viscosity of the extrusion resin liquid 12 is desirably at least the same as, or roughly higher than, the viscosity of the thermosetting resin liquid 1 as the main ingredient.
あまり粘度の低い樹脂液を用いると、樹脂液の粘度が低
いため、被洗浄用混合液を、ところてん式に押出すこと
はできないからである。This is because if a resin liquid with too low viscosity is used, the mixed liquid to be cleaned cannot be extruded in a one-to-one manner due to the low viscosity of the resin liquid.
以上のにうにしく、本発明の方法に」：す、残溜混合液

次回に装置を使用する際に、熱硬〜 ４ −
化１」樹脂液１と硬化剤３を装置始端から圧入し、該押
出し用樹脂液１２を押出せばよい。As described above, in the method of the present invention, the residual mixed liquid 15 is extruded from the inside of the apparatus, and then the extrusion resin liquid 1 is
2 remains. Since this resin liquid 12 for extrusion does not harden by itself, it is sufficient to leave it inside the apparatus. Then, when the apparatus is used next time, the thermosetting resin liquid 1 and the curing agent 3 are press-fitted from the starting end of the apparatus, and the extrusion resin liquid 12 is extruded.

端に、熱硬化性樹脂液１を導入ターるためのバイパス配
管１９を設けることにより、該熱硬化性樹脂液１を押出
せばよい。As the resin liquid 12 for extrusion, it is preferable to use the thermosetting resin liquid 1, which is the main ingredient, as it is. In that case, the thermosetting resin liquid 1 may be extruded by providing a bypass pipe 19 at the starting end of the apparatus for introducing the thermosetting resin liquid 1.
なお、洗浄時に硬化剤３が装置内へ流入しないように、
硬化剤３の受入れ口に弁２０を収り付（ｊでもよい。そ
の弁２０は、装置内部から押圧されると閉じる弁２０で
な（〕ればならない。In addition, to prevent the hardening agent 3 from flowing into the device during cleaning,
A valve 20 is installed in the receiving port for the curing agent 3 (it may also be a valve 20).The valve 20 must be a valve 20 that closes when pressed from inside the device.
本発明の洗浄方法による装置の洗浄は、従来の溶剤１７
による方法に比し、以下の点が優れている。Cleaning of the apparatus by the cleaning method of the present invention can be carried out using conventional solvent 17.
It has the following advantages over the method:
第１に、洗浄が短時間で可能である。したがって装置を
断続的に使用し、その都度洗浄１ノだい場合に、好都合
である。First, cleaning can be done in a short time. It is therefore advantageous if the device is used intermittently, with only one cleaning cycle each time.
第２に、押出し式洗浄であるため、装置内部に大量に混

で゛硬化し、装置が詰まるといった事態も発生しない。Second, since it is an extrusion type cleaning method, even if a large amount of mixed liquid remains inside the device, all of it can be removed. Therefore, there is no possibility that the mixed liquid will harden inside the device and the device will become clogged.
第３に、溶剤を使用しないため、衛生的である。Third, it is hygienic because no solvent is used.
第４に、押出し用樹脂液１２は、繰り返し使用できるた

使用（５供づる。This device uses a high-pressure pump 2 to guide a thermosetting resin liquid 1, which is a main ingredient, through a pipe 5, a metering pump 7, and a pipe 8 to the starting end of a mixer part 10 of the device.
Accordingly, the curing agent 3 is pumped into the pipe 6.1 by the pump 7, and the pipe 9.
through which it is also led to the beginning of mixer 6-part 10. Thermosetting resin liquid 1 led next
After mixing the hardening agent 3 with the mixer part 10 of the device, 1
Drain the duck from the outside of the device and use the mixed solution (15) (5 servings).

As a result, the extrusion resin liquid 12 is press-fitted into the inside of the apparatus. As a result, the mixed liquid 15 is pushed out of the apparatus through the pipe 11 connected to the terminal end of the mixer υ part 10. When all of the mixed liquid 15 has been extruded out of the device, cleaning has been completed. The extrusion resin liquid 12 remaining inside the device will be extruded out of the device in the same way the next time the device is used. be done.

Piping 9 connected to
are located on opposite sides of the central axis. Both intake ports also have valves 20 which close when the internal pressure of the mixer part 10 becomes higher than the internal pressure of the pipes 8 and 9. Therefore, when the injection of the thermosetting resin liquid 1 and the curing agent 3 is stopped and the extrusion resin liquid 12 is press-fitted, the valve 20 is closed.

という事態も発生しない。According to the cleaning method of this embodiment, it is possible to achieve the original effects of the invention, such as complete cleaning in a short time, due to the presence of the valve 20. Since the inflow of the curing agent 3 is prevented, a situation in which the resin liquid for extrusion is hardened inside the mixer part 10 does not occur.
