Drive shaft 3 on, drive drive shaft 3 to move straight down at this time.The movement straight down of drive shaft 3 has been completed at the same time following mistake
Journey: process 3.: due to drive shaft 3 sealed bottom and vertical sliding be connected in the dynamic trough 111 of drive seat 11, so when drive
When moving axis 3 moves straight down, the air pressure in dynamic trough 111 increases, and air pressure drives sliding block 133 to move to far from 1 center line of cylinder
Dynamic, the second liquid-leaking nozzle 134 on sliding block 133 is aligned with the first liquid-leaking nozzle 131 on the first demarcation plate 13 at this time, and reaction solution can
It is discharged to outside cylinder 1 along the first liquid-leaking nozzle 131, the second liquid-leaking nozzle 134 and Drainage pipe 16.Process is 4.: since sleeve 32 is perpendicular
Directly it is slidably connected in drive shaft 3, so when driving drive shaft 3 that paddle 31 is driven to move straight down, the position of sleeve 32
Set constant, sleeve 32 can drive the free end of paddle 31 to be swung up, so that paddle 31 be made to be in level.Paddle at this time
31 serve as filter plate.
The valve on Drainage pipe 16 is opened, Drainage pipe 16 is connect with external world's water pump or oil pump, is just completed pair
The quick filtering of waste water.
After the reaction was completed, lid 2 is rotated, after separating lid 2 with cylinder 1, drive shaft 3 is taken out, it will be able to driving
It is cleaned in axis 3, paddle 31 and cylinder 1.
What has been described above is only an embodiment of the present invention, and the common sense such as well known specific structure and characteristic are not made herein in scheme
Excessive description.It, without departing from the structure of the invention, can be with it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these also should be considered as protection scope of the present invention, these all will not influence what the present invention was implemented
Effect and patent practicability.
