Described upward feed liquor piston bottom end face is 25mm to the distance of last feed well end.
The beneficial effects of the utility model are: release adopts the two-stage releasing structure in the utility model, once can in pit shaft, the different depth aspect carry out twice release after the charging, two aspects are measured, improved effect, reduce release simultaneously and loaded the number of times of isotopic carrier, thereby reduced pollution.
Description of drawings
Fig. 1 is a main sectional view of the present utility model.
The specific embodiment
As shown in Figure 1, present embodiment has motor 1, and its output is connected with ball screw transmission mechanism 2, motor 1 and ball screw transmission mechanism 2 overcoat pressure-bearing pipes 5, be characterized in that described ball screw transmission mechanism 2 outputs are connected with by push rod 3 can realize the repeatedly multistage release 4 of release.
Described multistage release 4 comprises the last charging joint 4-1 that connects successively, last barrel 4-2 and last releasing-joint 4-3, the last charging joint 4-1 other end is fixedlyed connected with pressure-bearing pipe 5, described going up on the charging joint 4-1 offered inlet opening 4-4 and last feed well 4-5, installation matches with it and is fixed on last feed liquor piston 4-6 on the push rod 3 in the last feed well 4-5, described going up on the releasing-joint 4-3 offered release groove 4-7, installation matches with it and cuts the last release plunger 4-8 that is fixed on the push rod 3 in the last release groove 4-7, described upward feed liquor piston 4-6 bottom face equals the distance of release plunger 4-8 bottom face to last release groove 4-7 end to the distance of last feed well 4-5 end, in this example, this distance is 25mm; The described releasing-joint 4-3 end of going up connects charging joint 4-9 down successively, blanking tube 4-10, following releasing-joint 4-11 and lower contact 4-12, offer down charging hole 4-13 and following lead channel 4-14 on the described charging joint 4-9 down, installation matches with it and is fixed on following feed liquor piston 4-15 on the push rod 3 in the following lead channel 4-14, following feed liquor piston 4-15 bottom face maintains an equal level with following lead channel 4-14 terminal surface, offer down release groove 4-16 on the releasing-joint 4-11 under described, installation matches with it and is fixed on following release plunger 4-17 on the push rod 3 in the following release groove 4-16, and following release plunger 4-17 bottom face is fair with following release groove 4-16 terminal surface; The axial length of release groove piston 4-17 and following release groove 4-16 contact surface under the axial length of described feed liquor piston 4-15 down and following lead channel 4-14 contact surface equals, and this length is less than the distance of last feed liquor piston 4-6 bottom face to last feed well 4-5 end.
The operating principle of present embodiment is: under state shown in Figure 1, last barrel 4-2 and blanking tube 4-10 all are in closed state, isotopic carrier can not discharge, when a certain aspect need discharge isotopic carrier in well under the release, give motor 1 for positive electricity, drive 2 motions of ball screw transmission mechanism, thereby control push rod 3 moves 25mm to lower contact 4-12 direction, following lead channel 4-14 and following release groove 4-16 open, isotopic carrier begins to discharge, and still is in closed state and go up barrel 4-2 this moment; When need another degree of depth aspect be carried out the release of isotopic carrier in well, continue to give the positive electricity of motor 1 for identical numerical value, push rod 3 continues to move 25mm to lower contact 4-12 direction, feed well 4-5 and last release groove 4-7 open on this moment, last barrel 4-2 begins to discharge isotopic carrier, realizes that discharge the second time in the once charging; After release finishes, to propose well on the release, give motor 1 on ground, make push rod move 50mm and reset to motor 1 direction for negative electricity, make progress by last inlet opening 4-4 and following charging hole 4-13 respectively again and pour into isotopic carrier in barrel 4-2 and the blanking tube 4-10, prepare use next time.
