- the bottom wall 1 3 3 of the cup-shaped member 1 3 0 is formed with one groove 1 3 6 over an angular range of 2700 ° in the circumferential direction, while the moving body 1 6 0
- a protrusion (not shown) is formed downward from the bottom of the.
- the moving body 160 does not rotate around the axis, but moves in the axial direction, whereas the mouth 103 rotates around the axis, but does not move in the axial direction. Therefore, the protrusion and the groove 1 36 function as a stop that defines the stop positions of the rotor 10 3 and the moving body 1 60.
- the depth of the groove 1 36 is changed in the circumferential direction, and when the movable body 160 moves downward in the axial direction, the protrusion fits into the groove 1 3 6 and the rotor 10 3 The end of the groove 1 3 6 contacts the protrusion by rotation.

- the operation of the mixing pump device 1 of the present embodiment will be described more specifically.
- the first liquid LA for example, methyl alcohol
- the second liquid LB is sucked through the inflow channel 52.
- sucking water for example, water
- the mixing ratio of the first liquid LA and the second liquid LB is lower than the mixing ratio of the second liquid LB in the ratio (mixing ratio) of the first liquid LA and the second liquid LB.
- the uppermost stage is a reciprocating pump mechanism 1 The suction and discharge of 0 is shown.
- the suction by the reciprocating pump mechanism 10 is the direction in which the drive device 10 5 rotates clockwise, for example, so that the diaphragm valve 1 70 increases the internal volume of the pump chamber 11.
- the discharge by the reciprocating pump mechanism 10 is performed in the direction in which the driving device 105 rotates counterclockwise, for example, and the diaphragm valve 170 reduces the internal volume of the pump chamber 11. This is done by moving.
- the reciprocating pump mechanism 10 is stopped when the power supply to the drive unit 105 is stopped.
- the inflow side active valves 2 1 and 2 2 and the outflow side active valves 3 1, 3 2, 3 3, and 3 4 are open after a positive pulse is input, and negative pulses are When it is input, it switches to the closed state. Also, the inflow side active valves 2 1 and 2 2 and the outflow side active valves 3 1, 3 2, 3 3, and 3 4 are closed after a negative pulse is input. When it is input, it switches to the open state.
- the inflow side active valve 22 switches from the open state to the closed state.
- the inflow of the liquid LB from the inflow path 2 2 to the pump chamber 1 1 stops.
- the entire amount of 1 Z 2 flows into the pump chamber 11.
- the outflow side active valve 3 2 switches from the open state to the closed state. In this way, a mixed liquid in an amount corresponding to 1 Z 4 of the liquid flowing into the pump chamber 11 is discharged from the outflow path 62.
- Such an operation is performed in the same way in the other outflow channels 63, 64, but since the contents are the same, description thereof is omitted.
- the liquid mixed in the pump chamber 11 passes through the common flow path 8 1 and the chamber 8 2, and then flows out the flow paths 6 1, 6 2, 6 3. 6 4, even if the liquid composition of the mixed liquid varies depending on the position in the pump chamber 1 1, the mixed liquid is mixed in the pump chamber 1 1 and then the common flow path 8 1 and Mixing is also performed through chamber 82. Therefore, it is possible to prevent the concentration variation from occurring in the mixed liquid flowing out from each of the four outflow passages 61, 62, 63, 64. Even when the mixing pump device 1 is tilted and components tend to be biased in the pump chamber 11 1, the concentration of the liquid flowing out of each outflow path 6 1, 6 2, 6 3, 6 4 varies. Can be prevented.
- this branch point 80 has a structure in which the common flow path 8 1 and the outflow paths 61, 62, 63, 64 are directly connected, and the opening cross-sectional area is small. Therefore, no liquid stagnation occurs at the branch point 80, so the four outflow paths 6 1, 6 2 , 6 3 and 6 4, it is possible to prevent the concentration variation from occurring in the mixed liquid flowing out from each of the above.
- the chamber 8 2 is arranged so that the liquid outlet is located at the upper part, it is easy to discharge bubbles from the chamber 82. Therefore, it is possible to avoid a situation where a large bubble suddenly flows out from a specific outflow channel.
- outflow channels 61, 62, 63, and 64 extend horizontally from the branch point 80. For this reason, bubbles do not concentrate and flow out to a specific outflow path among the outflow paths 61, 62, 63, 64.
- the outflow channels 61, 62, 63, and 64 are arranged so as not to form sharp bent portions. Bubbles tend to accumulate at sharp bends, and the accumulated bubbles are separated from the inner walls of the outflow channels 61, 62, 63, and 64 after flowing out to a certain extent, but they form sharp bends. If not, bubbles are unlikely to stay. Therefore, it is possible to avoid a situation where a large bubble suddenly flows out from the outflow channels 61, 62, 63, 64.
- each of the inflow channels 51, 52 is opened in a direction in which the liquid that has flowed into the pump chamber 11 faces each other in the pump chamber 11. For this reason, every time the inflow of the liquid from the inflow path 51 and the inflow of the liquid from the inflow path 52 are switched, the flow in the pump chamber 11 is reversed and a turbulent flow is generated. In addition, since the inlets 5 1 5 and 5 2 5 of the inflow channels 5 1 and 5 2 are opened so that liquid flows in the direction along the inner wall of the pump chamber 1 1, in the pump chamber 1 1, A swirling flow is also generated.
- the liquid flowing in from each of the inflow channels 5 1 and 5 2 is agitated in the pump chamber 11 1 and sufficiently mixed and then flows out, so that the four outflow channels 6 1, 6 2, 6 3, 6 It is possible to prevent the concentration variation in the mixed liquid flowing out from each of the four.
- inflow channels 5 1 and 5 2 have the nozzle shape shown in Fig. 4 (a), or Fig. 4
- the liquid outlet 815 of the liquid to the common flow path 81 is disposed at a position farthest from the inlets 515 and 525. For this reason, it is possible to prevent the liquid flowing into the pump chamber 10 from flowing out of the pump chamber 10 without being sufficiently mixed.
- the first liquid LA with a low mixing ratio of LB Before the first liquid LA with a low mixing ratio of LB sucks into the pump chamber 11, a part of the second liquid LB with a high mixing ratio flows into the pump chamber 11 1. Since LA can be prevented from being unevenly distributed in the corner of the pump chamber 11, for example, in the vicinity of the diaphragm valve 170, the first liquid LA and the second liquid LB can be reliably mixed. In particular, in this embodiment, after the second liquid LB with a high mixing ratio is sucked to an amount corresponding to the total amount of 1 Z 2, the first liquid LA with a low mixing ratio is sucked into the pump chamber 11. Later, since the remaining 1Z2 of the second liquid LB is sucked into the pump chamber 11, the first liquid LA and the second liquid LB can be mixed more reliably.
