本発明は、重合体溶液などの過精製に用いら
れる洗浄装置付過機に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filter equipped with a cleaning device used for overpurifying polymer solutions and the like.
従来、重合体溶液などの過精製に用いたフイ
ルターを洗浄するには、過物の流れと逆方向に
過流体または溶剤を流す、いわゆる逆洗法が最
も一般的に行なわれている。しかし、この方法に
は次のような欠点がある。 Conventionally, in order to wash a filter used for overpurification of a polymer solution, etc., the most common method has been to flow a superfluid or a solvent in the direction opposite to the flow of the filter, which is the so-called backwashing method. However, this method has the following drawbacks.
(1) 逆洗流体は、流動抵抗の少ない部分により多
く流れるので、過面全体を均一に洗浄するこ
とが難しく、完全な洗浄再生は難しい。過面
全体を可能な限り均一に洗浄しようとすると、
大量の逆洗流体が必要となる。(1) Since more backwash fluid flows to areas with less flow resistance, it is difficult to uniformly clean the entire filter surface, making complete cleaning regeneration difficult. When trying to clean the entire surface as uniformly as possible,
Large amounts of backwash fluid are required.
(2) 過物の通常の流動方向と逆方向に洗浄流体
を流すので、フイルターの両側に補強が必要で
ある。(2) Since the cleaning fluid flows in the opposite direction to the normal flow direction of the filter, reinforcement is required on both sides of the filter.
本発明は、少量の洗浄液で無駄なく均一に洗浄
することができ、且つフイルターに特別な補強を
施す必要のない洗浄装置付過機を提供すること
を目的とし、その要旨は、ケーシングに流体の入

置を配置してなる洗浄装置付過機にある。 The purpose of the present invention is to provide a filter equipped with a cleaning device that can clean uniformly with a small amount of cleaning liquid without waste and does not require special reinforcement of the filter. An inlet and an outlet are provided, a cylindrical filter is disposed within the casing so as to block the gap between the inlet and the outlet, and a nozzle is provided inside the filter for spraying a cleaning liquid toward the inner surface of the filter. There is a filtration machine with a cleaning device in which a cleaning device is arranged.
以下、図面に示す実施例を参照しながら本発明

きる構造のものであれば、これに限定されるもの
ではない。 A cartridge type filter 4 is installed in the casing 1 so as to block the inlet 2 and the outlet 3. Filter 4 is wire mesh 4'
and a support frame 4'', and although the illustrated one is bucket-shaped, it is not limited to this, and any cylindrical shape such as a cylinder can be used.For example, the support frame 4'' is made of punched metal. A plate is used, but it is not limited to this as long as it supports the wire mesh 4' and allows permeation of excess fluid.

物、たとえばゲル化ポリマー、鉄錆などである。 The filter 4 is pressed against a bracket 7 of the casing 1 by a lid 5 of the casing 1 and a filter holder 6. The lid 5 has a pressure relief nozzle 5' inside the casing. What is separated by the filter 4 are insoluble foreign substances in the polymer solution, such as gelled polymers and iron rust.

中はこれらのバルブは全閉としておく。 On the other hand, the filter 4 is provided with an opening 8 at its bottom, through which a cleaning liquid injection nozzle rod 9 is inserted into the filter 4. Filter 4
and the bottom of the casing 1 are connected by a bellows 10, which closes the periphery of the axial tube of the nozzle rod 9. The bellows 10 is a conduit 1 for discharging cleaning liquid and waste from the filter 4.
1, 12, and 13. Casing 1
A conduit 14 is provided at the bottom of the filter 4 for discharging the cleaning liquid that has flowed out of the filter 4. Although not shown, on-off valves are attached to the conduit 13 and the conduit 14, and these valves are kept fully closed during the over-processing.

It is rotatably supported by the casing 1 by. Said gear 16 is driven by a motor 19 via a pinion 18 and is thereby able to rotate the nozzle rod 9.
また、ノズル杆９は下部にネジ部２０を有し、

This engages with a screw cut inside the bearing 17', causing the nozzle rod 9 to move up and down as it rotates. Switching between left and right rotation of the nozzle rod 9 is performed by reversing the motor 19.
The range in which the nozzle rod 9 moves up and down is the range in which the entire upper surface of the filter 4 is cleaned by the two nozzles 15. A cleaning liquid such as an organic solvent is pumped into the nozzle rod 9 from a cleaning liquid inlet 21 by a pump or the like.

ーの金網のメツシユにより異なるが、通常、長く
ても５分程度で済む。 In the cleaning device having the above structure, when cleaning the filter 4, the cleaning liquid is applied to the nozzle rod 9.
While spraying from the nozzle 15 to the inside of the filter 4, the nozzle rod 9 is rotated and moved up and down. The cleaning liquid is then sprayed uniformly over the entire surface of the filter. The liquid after cleaning falls by gravity and is returned to the cleaning liquid tank or the like through the pipes 11, 12, 13 and 14. Therefore, almost no liquid remains on the filter during cleaning, and the impact force or cleaning power of the subsequent cleaning liquid is not weakened. The higher the pressure of the injection liquid is, the more preferable it is, but it is usually 10 to 15 kg/cm 2 G, and the injection time varies depending on the mesh of the wire gauze of the filter, but is usually about 5 minutes at the longest.

is disposed inside the filter through the opening 8 provided at the bottom of the filter, but the present invention is not limited to this, and it is also possible to penetrate the lid 5 and dispose within the filter from the top of the filter.
本発明によれば、次の効果がある。 According to the present invention, there are the following effects.
従来のように逆洗法を行なうものとは異な
り、フイルター内部より過面全体を均一に洗
浄するので、フイルターに補強材を設ける必要
がない。 Unlike conventional backwashing methods, the entire filter surface is uniformly cleaned from inside the filter, so there is no need to provide a reinforcing material to the filter.
フイルターを噴射液によつて洗浄するから、
フイルターが目詰りしても少量の洗浄液で簡単

品と交換する必要がない。即ち、金網が破損し
た場合あるいはメツシユ数を変更する場合以外
は、殆んど新品と交換する必要がないから、金
網を節約し、ケーシングを解放するなどの交換
作業の手間を省くことができる。 Because the filter is cleaned with spray liquid,
Even if the filter becomes clogged, it can be easily cleaned and regenerated with a small amount of cleaning fluid, so there is no need to replace it with a new one as often as in the past. That is, unless the wire mesh is damaged or the number of meshes is changed, there is almost no need to replace it with a new one, so the wire mesh can be saved and the labor of replacement work such as releasing the casing can be saved.
洗浄にあたつてフイルターをケーシングから
取り外す必要がないので、環境汚染のおそれの
ある洗浄液を用いても作業環境が悪化すること
がなく、洗浄液の損失もなくなる。 Since there is no need to remove the filter from the casing for cleaning, the working environment will not be degraded even if a cleaning solution that may pollute the environment is used, and there will be no loss of cleaning solution.
