【発明の詳細な説明】
本発明は高粘度樹脂液混合装置の圧送方法に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pressure feeding method for a high viscosity resin liquid mixing device.
高粘度樹脂液混合装置（以下、「装置」と略す）
とは、高粘度の二液混合硬化性樹脂液の主剤と、
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。 High viscosity resin liquid mixing device (hereinafter abbreviated as “device”)
The main ingredient is a high viscosity two-component curable resin liquid,
A curing agent is taken in from the receiving port, mixed, and before the mixed liquid is hardened, the mixed liquid is discharged from the discharge port for use outside the device.
従来、かかる装置内部に残溜し、附着する混合
液の除去は、第５図に示す如く、溶剤１７を用い
て行なつていた。 Conventionally, the mixed liquid remaining inside the apparatus and attached thereto has been removed using a solvent 17, as shown in FIG.
即ち、装置の使用後に装置のミキサー部１０の
始端に連結した配管１４から、溶剤１７をポンプ
１６により注入し、ミキサー部１０及び配管１１
の内部に残溜する混合液１５を除去していた。こ
こに、配管１１とは、ミキサー部１０で混合した
混合液１５を、装置外部へ排出する配管である。
なお、図において、配管８は、主剤１を、装置の
ミキサー部１０の始端へ導く配管であり、配管９
は、硬化剤３を同じくミキサー部１０の始端へ導
く配管である。 That is, after using the apparatus, the solvent 17 is injected by the pump 16 from the pipe 14 connected to the starting end of the mixer part 10 of the apparatus, and the mixer part 10 and the pipe 11 are injected.
The mixed liquid 15 remaining inside was removed. Here, the pipe 11 is a pipe that discharges the mixed liquid 15 mixed in the mixer section 10 to the outside of the apparatus.
In addition, in the figure, piping 8 is a piping that guides the base agent 1 to the starting end of the mixer section 10 of the device, and piping 9
is a pipe that similarly guides the curing agent 3 to the starting end of the mixer section 10.
しかし、従来の、溶剤１７を用いた除去方法
は、以下のような欠点を有していた。 However, the conventional removal method using solvent 17 had the following drawbacks.
第１に、溶剤１７の置換能力は低く、装置内の
置換に長時間を要した。そのため、装置の断続的
使用に際しては、その都度装置内を置換する必要
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 displacement ability of the solvent 17 was low, and it took a long time to replace the solvent in the apparatus. Therefore, when the device is used intermittently, it is necessary to replace the inside of the device each time, but this requirement cannot be satisfactorily met, reducing the efficiency of use of the device.
第２に、同じく溶剤１７の置換能力が低いこと
に起因し、装置のミキサー部１０の内部及び配管
１１の内部に大量に混合液１５が附着している場
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、装置を詰まらせる事態が発生
した。そのため、装置の分解、整備に貴重な時間
と費用を要した。 Secondly, due to the low substitution ability of the solvent 17, if a large amount of the mixed liquid 15 adheres to the inside of the mixer section 10 and the inside of the piping 11 of the device, it cannot be removed completely and often remains. The mixed liquid in the tank hardened inside the equipment, causing the equipment to become clogged. Therefore, disassembling and servicing the device required valuable time and money.
本発明は、従来の圧送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置
換することができ、かつ、確実に装置内部の混合
液を除去できる、圧送方法を提供するものであ
る。 The present invention was devised in view of the drawbacks of the conventional pressure-feeding method, and provides a pressure-feeding method that can replace the inside of the device in a short time and can reliably remove the mixed liquid inside the device. This is what we provide.
即ち、本発明にかかる圧送方法は、主剤および
硬化剤からなる二液混合硬化性樹脂液の混合圧送
の終了から次の主剤および硬化剤から二液混合硬
化性樹脂液の混合圧送開始までの間、該高粘度樹
脂液混合装置の始端から該高粘度樹脂液と同程度
の該高粘度樹脂液を押出し用樹脂液を圧入し、押
出し用樹脂液により、該高粘度樹脂液を、終端の
排出口から押出し、押出し用樹脂液は該高粘度樹
脂液混合装置内の残存させるものである。 That is, the pressure-feeding method according to the present invention covers the period from the end of the mixed pressure-feeding of the two-component mixed curable resin liquid consisting of the base resin and the curing agent to the start of the next mixed pressure-feeding of the two-component mixed curable resin liquid from the base resin and the curing agent. , the extrusion resin liquid is press-injected into the high viscosity resin liquid to the same extent as the high viscosity resin liquid from the starting end of the high viscosity resin liquid mixing device, and the extrusion resin liquid is used to discharge the high viscosity resin liquid at the terminal end. The extrusion resin liquid is extruded from the outlet and left in the high viscosity resin liquid mixing device.
したがつて、押出し用樹脂液１２の粘度は、主
剤１の粘度と少なくとも同程度、あるいは、さら
に高粘度のものが望ましい。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、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。 Therefore, the viscosity of the extrusion resin liquid 12 is desirably at least as high as the viscosity of the base resin 1, or even higher. This is because if a resin liquid whose viscosity is too low is used, the mixed liquid cannot be extruded in a one-to-one manner due to the low viscosity of the resin liquid.
以上のようにして、本発明の方法により、残溜
混合液１５を装置内部から押出すと、後には押出
し用樹脂液１２が残る。この押出し用樹脂液１２
は、単独では硬化しないため、装置内部に放置し
てよい。そして次回に装置を使用する際に、主剤
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, when the residual mixed liquid 15 is extruded from the inside of the apparatus by the method of the present invention, the resin liquid 12 for extrusion remains behind. This extrusion resin liquid 12
cannot be cured by itself, so it can be left inside the device. Then, when the apparatus is used next time, the base material 1 and the curing agent 3 are press-fitted from the starting end of the apparatus, and the extrusion resin liquid 12 is extruded.
押出し用樹脂液１２として、主剤１をそのまま
用いてもよい。その場合は、装置始端に、主剤１
を導入するためのバイパス配管１９を設けること
により、該主剤１を押出せばよい。 The base resin 1 may be used as it is as the resin liquid 12 for extrusion. In that case, add 1 base agent at the beginning of the device.
The base material 1 may be extruded by providing a bypass pipe 19 for introducing the main material 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を取り付け
てもよい。その弁２０は、装置内部から押圧され
ると閉じる弁２０でなければならない。 Note that a valve 20 may be attached to the receiving port for the curing agent 3 so that the curing agent 3 does not flow into the apparatus during cleaning. The valve 20 must be a valve 20 that closes when pressed from inside the device.
本発明の圧送方法による装置内の置換は、従来
の溶剤１７による方法に比し、以下の点が優れて
いる。 The displacement within the apparatus by the pressure feeding method of the present invention is superior to the conventional method using solvent 17 in the following points.
第１に、洗浄が短時間で可能である。したがつ
て装置を断続的に使用し、その都度置換したい場
合に、好都合である。 First, cleaning can be done in a short time. This is therefore advantageous when the device is used intermittently and it is desired to replace it each time.
第２に、押出し式であるため、装置内部に大量
に混合液が残溜している場合でも、そのすべてを
除去できる。したがつて、混合液が装置内部で硬
化し、装置が詰まるといつた事態も発生しない。 Second, since it is an extrusion type, even if a large amount of mixed liquid remains inside the device, all of it can be removed. Therefore, a situation where the mixed liquid hardens inside the device and the device becomes clogged does not occur.
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
できるため経済的である。 Fourthly, the extrusion resin liquid 12 is economical because it can be used repeatedly.
また本発明の洗浄方法は、装置のミキサー部
が、スタテツクミキサーであつても、あるいは動
力ミキサーであつても適用可能である。 Further, the cleaning method of the present invention is applicable even if the mixer section of the apparatus is a static mixer or a power mixer.
以下、図に示す実施例を説明することにより、
本発明をさらに詳しく説明する。 Hereinafter, by explaining the embodiment shown in the figure,
The present invention will be explained in more detail.

Accordingly, the curing agent 3 is guided through the pipe 6, the metering pump 7, and the pipe 9 to the starting end of the mixer section 10 as well. Next, the main agent 1 and curing agent 3 that have been introduced are mixed in the mixer section 10 of the device, and then discharged to the outside of the device through the pipe 11, and the mixed liquid 15 is provided for use.

る。 In the case of this embodiment, a pipe 1 for pressurizing the resin liquid 12 for extrusion into the starting end of the mixer section 10 of the apparatus.
4 is attached separately, and a high-pressure pump 13 connected to the other end of the pipe 14 presses the extrusion resin liquid 12 into 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 section 10. When all of the mixed liquid 15 is pushed out of the device, the pressure feeding is completed. The extrusion resin liquid 12 remaining inside the apparatus is similarly extruded to the outside of the apparatus when the apparatus is used next time.

入すると弁２０は閉じる。 In this embodiment, the positional relationship between the piping 14, the piping 8, and the piping 9 at the starting end of the mixer section 10 is as shown in FIG. That is, on the extension of the central axis of the tubular mixer section 10, there is a pipe 14 for press-fitting the resin liquid 12 for extrusion, and perpendicular to the central axis there is a pipe 8 connected to the receiving port for the base material 1, and a hardening agent 3. Pipes 9 connected to the receiving ports are located on opposite sides of the central axis. In addition, at the reception port,
Both have a valve 20, which is connected to the mixer section 1.
When the internal pressure of 0 becomes higher than the internal pressure of piping 8 and piping 9, it closes. Therefore, when the injection of the base material 1 and the curing agent 3 is stopped and the extrusion resin liquid 12 is press-fitted, the valve 20 is closed.
