Description
【０００１】[0001]
本考案は、管等の流路内面に付着したスケールを除去し洗浄するとともに内面 の腐食および内面へのスケールの再付着を防止する流路内面洗浄装置に関する。 The present invention relates to a channel inner surface cleaning device that removes and cleans scale adhering to the inner surface of a channel such as a pipe and prevents corrosion of the inner surface and re-adhesion of scale to the inner surface.
【０００２】[0002]
建物内部や金型等の機器内に通水管や流路を形成し、空調や機器の冷却用に冷 却水等を通水させることがあるが、長期間使用していると通水管の内部に錆が発 生したり、カルシウム分やシリカ等のスケールが付着し、管内の開口面積が狭く なるという問題があった。このようにして通水管内の開口面積が狭められると流 路の通水抵抗が増大し、通水量を十分確保できなくなり、冷却効率の低下を引き 起こすことがある。また飲料水の蛇口を開いた際に、通水管内に付着しているス ケールの一部が脱落して、蛇口から着色した水が流れ出ることがある。従来、こ のように通水管内にスケール等が付着した場合には、通水管の内部を機械的に清 掃してスケール等を除去したり、あるいは通水管全体の交換等を行っていた。 Water pipes and channels may be formed inside equipment such as buildings and molds to allow the passage of cooling water for air conditioning and equipment cooling. There was a problem that rust was generated on the tube and scales such as calcium and silica adhered, which narrowed the opening area in the tube. When the opening area in the water pipe is narrowed in this way, the water flow resistance of the flow channel increases, and it becomes impossible to secure a sufficient water flow rate, which may cause a decrease in cooling efficiency. In addition, when the faucet for drinking water is opened, part of the scale adhering to the inside of the water pipe may fall off and colored water may flow out from the faucet. Conventionally, when scale or the like adheres to the inside of the water pipe as described above, the inside of the water pipe is mechanically cleaned to remove the scale or the like, or the entire water pipe is replaced.
【０００３】[0003]
しかしながら、建物内の通水管も金型内部の流路にしてもそれぞれ内部に複雑 に延びており、特に建物内等に設置されている通水管の総延長は相当な長さとな り、通水管の内部に清掃用のブラシ等を差し入れて内面に付着したスケールを除 去する方法では、時間と手間が非常にかかるという問題があった。又金型の場合 、流路を清掃するために金型を分解しなければならず、成型作業が中断されてし まうという問題があった。更に、建物の通水管を取り替える場合には、壁や床を はがす等の大掛かりな作業が必要となり、費用が大きいばかりでなく長期間水の 使用ができなくなるという問題があった。 However, the water pipes in the building also extend inwardly even if they are the flow paths inside the mold, and the total length of the water pipes installed in the building, etc. is particularly considerable, and the water pipes The method of inserting a cleaning brush or the like into the inside to remove the scale adhering to the inner surface has a problem that it takes much time and labor. Further, in the case of a mold, there is a problem that the mold must be disassembled in order to clean the flow path, and the molding operation may be interrupted. Furthermore, when replacing the water pipes of a building, large-scale work such as peeling off walls and floors is required, which is not only costly but also unusable for a long time.
【０００４】[0004]
本考案では、上記課題を解決するため、スケールを除去するための流路内面洗 浄装置を次のように構成した。 In the present invention, in order to solve the above problems, a flow path inner surface cleaning device for removing scale is configured as follows.
【０００５】 すなわち、有機酸からなる酸性液にリン酸亜鉛ストロンチウム等のリン酸塩を 混合して洗浄液を調合し、この洗浄液を所定量貯蔵する貯蔵槽と、この貯蔵槽か ら洗浄液を吸引し、水管や金型等被洗浄機器内に洗浄液を送出するポンプと、被 洗浄機器から洗浄液を貯蔵槽内に戻す配管と、洗浄液を濾過するフィルタ等から 流路内面洗浄装置を構成し、洗浄液を流路内面洗浄装置から被洗浄機器の流路内 に送り込み、そしてそれを回収して循環させることとした。That is, a cleaning liquid is prepared by mixing a phosphate such as zinc strontium phosphate with an acidic liquid consisting of an organic acid, and a storage tank for storing a predetermined amount of the cleaning liquid and suctioning the cleaning liquid from the storage tank. , A pump that delivers the cleaning liquid into the equipment to be cleaned such as water pipes and molds, a pipe that returns the cleaning fluid from the equipment to be cleaned into the storage tank, a filter that filters the cleaning fluid, and so on. It was decided to send it from the channel inner surface cleaning device into the channel of the equipment to be cleaned, and to collect and circulate it.
【０００６】 したがって、送り込まれた洗浄液の酸性成分によって管内等に付着したスケー ルが溶解され、洗浄液とともに流出して除去され、その後スケールが除去された 内面にリン酸塩による亜鉛膜等の被覆が施され表面層が保護される。これにより 、金型内の流路や通水管の開口面積を広げ、通水性を向上させて冷却効率や生産 性等を高めることができ、かつ形成された皮膜によって流路内面を長期間清浄な 状態に保持することができる。[0006] Therefore, the scale adhering to the inside of the pipe or the like is dissolved by the acidic component of the sent cleaning liquid, flows out and is removed together with the cleaning liquid, and then the scale is removed. Applied to protect the surface layer. As a result, the flow passage in the mold and the opening area of the water passage can be expanded to improve water permeability and enhance cooling efficiency and productivity, and the formed film keeps the inner surface of the passage clean for a long time. Can be held in a state.
【０００７】 尚、液温を上昇させる加熱器を内部に設置し、所定の温度に昇温させた洗浄液 を被洗浄機器に循環させるようにしてもよい。液温を上昇させた場合には、スケ ールの溶解速度を促進させることができる。A heater for raising the liquid temperature may be installed inside and the cleaning liquid heated to a predetermined temperature may be circulated through the equipment to be cleaned. When the liquid temperature is increased, the scale dissolution rate can be accelerated.
【０００８】 又、内部にＰＨ測定器を設け、循環している洗浄液や貯蔵槽内の洗浄液のＰＨ 値を測定するようにしてもよい。このようにすると、被洗浄機器の内部に付着し ているスケールが洗浄液に溶解されたことを洗浄液のＰＨ値の低下から計測でき 、例えばＰＨ値の変動から被洗浄機器内部におけるスケールの洗浄状態を推測し たり、あるいはＰＨ値の限界を予め定めておき、限界値に達したときに洗浄液の 交換や補充の必要を感知し、あるいはそれらの指示を発するようにできる。Further, a PH measuring device may be provided inside to measure the PH value of the circulating cleaning liquid or the cleaning liquid in the storage tank. By doing this, it can be measured that the scale adhering to the inside of the equipment to be cleaned is dissolved in the cleaning liquid from the decrease in the PH value of the cleaning liquid. It is possible to make a guess or set a limit on the PH value in advance, and when the limit value is reached, it is possible to sense the need for replacement or replenishment of the cleaning liquid, or to issue such an instruction.
