The 1 nozzle outer wall of colorimetric tube body is connect with 2 inner thread of pipe cap, and 2 center position of pipe cap is provided with outer wall and is provided with
The retainer plate 3 of screw thread, the pipe cap 2, which is located in retainer plate 3, is provided with button motor 4, and the output shaft of button motor 4 is fixed with
Wire winding tube 5, the cross section of the wire winding tube 5 are by rectangle and to be symmetrically distributed in the knot that the isosceles trapezoid of rectangle two sides constitutes
Structure prevents the rope for being looped around wire winding tube 5 13 to be detached from away from 5 both ends of wire winding tube, and the button motor 4 is with setting in pipe cap 2
Power supply on lateral wall is electrically connected, the small nozzle diameter due to colorimetric tube body 1 of the diameter of the retainer plate 3, and retainer plate 3
Outer wall thread is connected with limiting cylinder 6, and the bottom end of the limiting cylinder 6 is at the position in its bottom end center of circle to limiting cylinder 6
Cylinder table 7 inside being extended to form, and 7 upper end of cylinder table is open state, 7 outer wall of cylinder table slidably connects cartridge filter 8,
8 inner wall of cartridge filter is equidistantly provided with the limited block 14 that cross section is " T " shape structure, and limited block 14 and edge along its length
The limiting slot that 7 length of cylinder table opens up is slidably connected, and cartridge filter 8 can be made to move up and down along 7 side wall straight line of cylinder table, prevented
Filter cylinder 8 in moving process run-off the straight and be flowed into solution in colorimetric tube body 1 from 9 edge of filter cap, and then influence
The filter effect of filter cap 9, and 8 upper end outer wall thread of cartridge filter is connected with flexible filter cap 9, has the effect of vibration
Fruit, improve filter effect simultaneously, also facilitate sediment to drop into limiting cylinder 6, the length of the limiting cylinder 6 be greater than or
Equal to the sum of cartridge filter 8 and the length of cylinder table 7, cartridge filter 8 can be made arbitrarily to move a certain height, institute along the outer wall of cylinder table 8
Stating 9 cross section of filter cap is domes, is slided into limiting cylinder 6 convenient for sediment from filter cap 9, to can be effectively prevented
The mesh of filter cap 9 is deposited object blocking, and the pipe cap 2, which is located at the position right above filter cap 9, offers solution injection hole
10, the diameter of the solution injection hole 10 is less than or equal to the diameter of filter cap 9, in order to ensure incidence to be measured in the process can
Filter cap 9 is passed fully through, so as to separate the solution in solution to be measured more thoroughly with sediment, and 10 inner wall of solution injection hole
It is threaded with matched sealing-plug 11,8 side wall of cartridge filter is provided with fixed ring 12, and is arranged in fixed ring 12
There is rope 13, the rope 13 is connect with wire winding tube 5.
Working principle: in use, being first threadedly coupled cartridge filter 8 with filter cap 9, since cartridge filter 8 and filter cap 9 are
It is threadedly coupled, it is easy for installation, to be convenient for changing filter cap 9, then, cartridge filter 8 is threadedly coupled with retainer plate 3, finally will
Colorimetric tube body 1 is threadedly coupled with pipe cap 2, and sealing-plug 11 is opened, and enters the injection of hole 10 to side solution to solution master, at this point,
Filter cap 9 is passed through by limiting cylinder 6 to side solution, under the action of filter cap 9, will be filtered to the sediment in the solution of side
Onto filter cap 9, since filter cap 9 has elasticity, when sediment is fallen on filter cap 9, at this point, filter cap 9 plays
The effect of vibration, in addition, the city section of filter cap 9 is domes, is fallen on filter cap 9 so that filter effect can be improved
Sediment by being slipped in limiting cylinder 6 from filter cap 9 under self-acting, it is therefore prevented that the mesh quilt on filter cap 9
It blocks and the solution to be measured that influences detection efficiency, and be filtered is directly over cylinder table 7 drops into colorimetric tube body 1,
When containing a large amount of sediment in solution to be measured, at this point, button motor 4 can be started (herein it should be noted that button motor
For its output shaft can be made to make the output motor of positive and negative rotation campaign), wire winding tube 5 starts to rotate with the output shaft side of button motor 4
Side rope closing rope 13, rope 13 drive cartridge filter 8 to rise along 7 side wall of cylinder table, and cartridge filter 8 is equivalent to increase in the process of rising
The height of cylinder table 7, so that the volume between 7 outer wall of limiting cylinder 6 and cylinder table is increased indirectly, it is more so as to accommodate
Sediment, also avoid precipitate bulk cause on filter cap 9 filter cap 9 mesh be blocked, thus it is sustainable to than
Injection solution to be measured in colour tube ontology 1, and then detection efficiency can be improved.
