Magnetic line of force M is in the side of the outer wall near the 1st cylindrical body 61 or almost parallel with the cylinder axle of the 2nd cylindrical body 62 in the side of the inwall of close 2nd cylindrical body 62. In addition, magneticflux-density is roughly equal with the side of the inwall of close 2nd cylindrical body 62 in the side of the outer wall near the 1st cylindrical body 61.

<3-1>overall action

Next, the action in the control portion 190 of the liquid rinse system of present embodiment is described.

Fig. 8 and Fig. 9 is the schema of the action in the control portion 190 of the liquid rinse system illustrating present embodiment.

First, control portion 190 determines whether to use magnetic filter device 1A (step S1). Specifically, control portion 190 is according to the identifying information of the magnetic filter device being stored in storer 292 judges whether magnetic filter device 1A was carried out back washing process last time. Further, when last time magnetic filter device 1A having carried out back washing process, control portion 190 is judged to employ magnetic filter device 1A.

In step sl, if it is determined that employing magnetic filter device 1A (step S1: yes), the air T-valve 134,136 of magnetic filter device 1A is controlled the air supply target of compressed air source 138 is switched to upper port 142a side (step S2) by control portion 190. Now, the linking objective that the air T-valve 134,136 of magnetic filter device 1A controls to join air pipe 135 is switched to air to join pipe 142 side by control portion 190.

Next, control portion 190 makes compressed air source 138 carry out action (step S3). Now, in magnetic filter device 1A, import pressurized air from the upper port 142a of processing vessel 6 to the top of the magnet unit 2 magnet room S2.Thus, magnet unit 2 is fixed in the lower section of magnet room S2, completes the preparation using magnetic filter device 1A.

On the other hand, in step sl, if it is determined that not using magnetic filter device 1A (step S1: no), then the air T-valve 134,136 of magnetic filter device 1B is controlled the air supply target of compressed air source 138 is switched to upper port 142a side (step S4) by control portion 190. Now, the linking objective that the air T-valve 134,136 of magnetic filter device 1A controls to join air pipe 135 is switched to air to join pipe 142 side by control portion 190.

Next, control portion 190 makes compressed air source 138 carry out action (step S5). Now, in magnetic filter device 1B, import pressurized air from the upper port 142a of processing vessel 6 to magnet room S2 for the top of magnet unit 2. Thus, magnet unit 2 is fixed in the lower section of magnet room S2, completes the preparation using magnetic filter device 1B.

Next, control portion 190 opens valve 98 (step S6). Thus, from withdrawing can 106 via joining pipe 114, magnetic filter device 1A (or magnetic filter device 1B), join pipe 118 and open-minded through the stream road of surge tank 104.

Hereafter, control portion 190 drives pump 90 (step S7). Thus, after being stored in the use of withdrawing can 106, refrigerant is inhaled by pump 90, and the process fluid being admitted to magnetic filter device 1A (or magnetic filter device 1B) imports discharge port 8a. In addition, when pump 90 is driven, control portion 190 omits the process of step S4.

Thus, after being admitted to the use of process fluid importing discharge port 8a, refrigerant is guided to treatment chamber S1. Further, be filtered in treatment chamber S1 material 4 filter refrigerant through joining, pipe 118 flows into surge tank 104.

Next, control portion 190 obtains the value (step S8) of pressure transmitter 120.

Next, control portion 190 judges that the value of acquired pressure transmitter 120 is whether below prescribed value (step S9). In step s 6, when the value of pressure transmitter 120 is below prescribed value (step S9: yes), control portion 190 carries out the process of step S5 again. On the other hand, in step s 6, when the value of pressure transmitter 120 exceedes prescribed value (step S9: no), control portion 190 shutoff valve 98 (step S11).

In magnetic filter device 1A, 1B, it is filtered, at dirt, the result that material 40 catches, creates so-called blocking. Now, pump 90 send pressure increase. Therefore, in magnetic filter device 1A, control portion 190 sends pressure by means of what pressure transmitter 120 monitored pump 90, when pump 90 send pressure exceed prescribed value, shutoff valve 98, carries out the preparation of back washing process described later.

In step s 11, valve 98 is closed, and thus, after the cleaning that magnetic filter device 1A flows out, refrigerant flows into energy storage 96, stores refrigerant after cleaning in energy storage 96.

Hereafter, control portion 190 judges whether have passed through the specific time (step S12) for refrigerant after energy storage 96 storage cleaning from shutoff valve 98. Here, the CPU200 in control portion 190 uses such as built-in timer to carry out timing. In addition, specific time according to the capacity of energy storage 96 and in the per unit time refrigerant set from magnetic filter device 1A, 1B to the influx of energy storage 96.

Next, control portion 190 judges that whether the back washing of last time processes taking magnetic filter device 1A as object (step S13).Specifically, according to the identifying information of the magnetic filter device 1A being stored in storer 292, control portion 190 judges that whether the back washing of last time processes taking magnetic filter device 1A as object.

In step s 13, when the back washing process of last time is by object of magnetic filter device 1A (step S13: yes), the air T-valve 134,136 of magnetic filter device 1B is controlled the air supply target of compressed air source 138 is switched to lower port 143a side (step S14) by control portion 190. Now, for magnetic filter device 1B, the linking objective that air is joined pipe 135 by control portion 190 switches to air to join pipe 142 side.

Next, control portion 190 makes compressed air source 138 carry out action (step S15). Now, in magnetic filter device 1B, import pressurized air from the lower port 143a of processing vessel 6 to the lower section of the magnet unit 2 magnet room S2. Thus, magnet unit 2 is fixed in the top of magnet room S2, completes the preparation that magnetic filter device 1B carries out back washing process. Hereafter, control portion 190 carries out back washing process (step S16). The details that this back washing processes is described in detail by<3-2>.

On the other hand, in step s 13, if the back washing process of last time is not taking magnetic filter device 1A as object, that is, the back washing of last time processes taking magnetic filter device 1B as object (step S13: yes). In this case, the air T-valve 134,136 of magnetic filter device 1A is carried out controlling to switch to the path from compressed air source 138 lower port 143a side (step S17) by control portion 190. Now, the air T-valve 134,136 of magnetic filter device 1B is carried out controlling the path from compressed air source 138 is switched to upper port 142a side by control portion 190.

Next, control portion 190 makes compressed air source 138 carry out action (step S18). Now, in magnetic filter device 1A, import pressurized air from the lower port 143a of processing vessel 6 to the lower section of the magnet unit 2 magnet room S2. Thus, magnet unit 2 is fixed in the top of magnet room S2, completes the preparation that magnetic filter device 1A carries out back washing process. Hereafter, control portion 190 carries out back washing process (step S16). The details that this back washing processes is described in detail by<3-2>.

As described above, in the liquid rinse system of present embodiment, alternately magnetic filter device 1A, 1B are cleaned.

<3-2>back washing processes

Next, the back washing process of the liquid rinse system of present embodiment is described in detail.

Figure 10 is the schema of the action of the back washing process in the control portion 190 illustrating present embodiment. In addition, Figure 11��Figure 13 is the action explanation figure of the magnetic filter device 1A (1B) of present embodiment.

First, the stream road of refrigerant be set to from pump 90 in order via joining pipe 8, treatment chamber S1 and flowing to joins Guan10Liu road (the 1st stream road).

In this condition, first, liquid tee valve 18 is carried out controlling to be switched to the linking objective joining pipe 10 to join pipe 22 side (step S21) by control portion 190. Thus, the stream road of refrigerant switches to from above-mentioned 1st stream road and flows into treatment chamber S1 Nei Liu road (the 2nd stream road) from pump 90 through the both sides joining pipe 8 and joining pipe 10. Further, as shown in figure 11, by means of pump 90, even if for through joining pipe 22, liquid tee valve 18 and join Guan10Liu road, it is also possible to supply refrigerant (arrow with reference in Figure 11) in the treatment chamber S1 of processing vessel 6.Now, the liquid level of refrigerant is sent position by the top, leading section that pressure pushes match well pipe 10 to by pump 90. Further, the air being stored in the air storage area A1 of the top for the treatment of chamber S1 becomes the state of cooled agent compression.

Control portion 190 carry out liquid tee valve 16 controlling being switched to by the linking objective joining pipe 8 being connected with treatment chamber S1 be connected with de-liquid/solidified cell 100 join pipe 116 side (step S22). Thus, the stream road of refrigerant switches to from above-mentioned 2nd stream road from pump 90 in order via the stream road (the 3rd stream road) joining pipe 10, the treatment chamber S1 flow direction joins pipe 8. Further, as shown in figure 12, by means of the pressure of the air compressed being stored in air storage area A1, import the refrigerant in treatment chamber S1 and flow out (arrow with reference in Figure 12) to joining pipe 116 smoothly.

Next, whether control portion 190 judges after switching the linking objective joining pipe 8 and joining the linking objective of pipe 10 through specific time (step S23). As long as not through specific time, then control portion 190 maintains standby state (step S23: no).

Now, as shown in figure 13, the refrigerant supplied by pump 90 is lastingly through joining pipe 22 and supply in treatment chamber S1 (arrow with reference in Figure 13). Thus, filtering material 4 is flowed to the refrigerant cleaning flowing to contrary direction with refrigerant during use magnetic filter device 1A (1B).

In step S23, if it is determined that through specific time (step S23: yes), then liquid tee valve 18 is carried out controlling to switch to the linking objective joining pipe 10 to join pipe 118 side (step S24) by control portion 190.

Hereafter, control portion 190 makes pump 90 stop (step S25). In addition, control portion 190 can not also carry out the process of step S25 and continue to drive pump 90.

Finally, control portion 190 carry out liquid tee valve 16 controlling being switched to by the linking objective joining pipe 8 be connected with pump 90 join pipe 114 side (step S26).

<4>sum up

But, for the structure not being configured with yoke in treatment chamber S1 (such as, the magnetic filter device 1001 of the comparative example shown in Fig. 6), in most of the cases, magnetic line of force is from certain magnetic pole different magnetic pole towards other near magnet unit. Therefore, in treatment chamber S1, near magnet unit 2, the intensity in magnetic field becomes big, but in the position away from magnet unit 2, the decrease in strength in magnetic field.

On the other hand, in the magnetic filter device 1A (1B) of present embodiment, it is configured to magnetic line of force is introduced the direction away from magnet unit 2 due to yoke 41, accordingly, it may be possible to prevent the decline of the intensity in the magnetic field of the position away from magnet unit 2.

This result, for the magnetic field that multiple magnetic poles of magnet unit 2 produce respectively in treatment chamber S1, it is possible to reduce with process after the laying particular stress on of distribution of intensity in magnetic field in the vertical direction of the flow direction of refrigerant.

In addition, liquid tee valve 16,18 is controlled that the stream Lu Cong 1 of refrigerant flows road and switches to the 2nd stream road by control portion 190, and thus, the air being present in air storage area A1 is compressed. Hereafter, liquid tee valve 16,18 is controlled that the stream Lu Cong 2 of refrigerant flows road and switches to the 3rd stream road by control portion 190, thus, the refrigerant being present in treatment chamber S1 is released to joining pipe 8 smoothly under the effect of the pressure of the air being present in air storage area A1. Now, owing to being attached to the dirt of the ferromagnetic particle etc. of filtering material 4, cooled agent is cleaned and flow away, and therefore, eliminates the blocking of filtering material 4.

In addition, between 2 yoke 341a, filtering material 4 it is configured with.

Further, a part for the cylinder axle around processing vessel 306 that magnet unit 302a is configured in the outer wall with processing vessel 306 is to putting. In addition, magnet unit 302a is made up of 1 magnet of the shape with substantially C-shaped, 2 leading sections respectively with yoke 341a magnetic coupling.2 leading sections of magnet unit 302a become magnetic pole.

The structure shown in (a) in magnet unit 302b and Figure 16 of the outside being configured at processing vessel 306 of the magnetic filter device shown in (b) in Figure 16 is different.

In magnet unit 302b, 3 magnet 302b1 configure with the state of stacking. The magnetic pole (N pole and N pole or S pole and S pole) that adjacent 2 magnet 302b1 are configured to identical polar each other is relative. Further, the boundary section of adjacent 2 magnet 302b1 is arranged in the position corresponding with yoke 341a of the outer wall of processing vessel 306. In addition, the boundary section of adjacent 2 magnet 302b1 of magnet unit 302b becomes magnetic pole.

In addition, yoke 341b is configured on the cylinder axis direction of processing vessel 306 across the boundary section of adjacent 2 magnet 302b1 forming magnet unit 302b. Thus, owing to the composition from the magnetic flux being leaked to outside yoke 341b the magnetic flux that the boundary section of adjacent 2 magnet 302b1 is radiated can be reduced, accordingly, it may be possible to effectively apply flexibly the magnetic flux radiated from magnet unit 302a.
