Wherein, there are several baffles 41 in secondary slot 4, standby liquid bath 42 is constituted between 4 cell wall of several baffles 41 and secondary slot.
As shown in Figure 1, liquid guiding cavity 6 is located between primary slot 4 and secondary slot 4, liquid guiding cavity 6 have be oppositely arranged up and down and
The upper liquid guiding cavity 61 and lower liquid guiding cavity 62 of perforation, upper liquid guiding cavity 61 away from horizontal height be all larger than primary slot 2 and secondary slot 4 away from
Horizontal height；
Wherein, branch inlet tube 31 is also connect with lower liquid guiding cavity 61, and correspondence offers inlet opening 62.1 on lower liquid guiding cavity 62.
Wherein, a kickboard 62.2 has been horizontally set in lower liquid guiding cavity 62, kickboard 62.2 has and lower 62 bottom surface size pair of liquid guiding cavity
The end face answered, kickboard 62.2 separate upper liquid guiding cavity 61 and lower liquid guiding cavity 62, and kickboard 62.2 passes through sliding rail and lower drain
62 cavity wall of chamber connects and the kickboard 62.2 is installed on 62.1 upper end of inlet opening.
Wherein, the side wall of upper liquid guiding cavity 61 and top offer wears groove 61.1, and main separating tube 8 is from side wall
It is extended through between wears groove 61.1 outside supreme liquid guiding cavity 61, main separating tube 8 be located in upper liquid guiding cavity 61 one section, which extends to, to be located at
Outside the wears groove 61.1 on top.
It sees on the whole, the fixed end face line between primary slot 2, liquid guiding cavity 6 and secondary slot 4 is in deposition.
As depicted in figs. 1 and 2, liquid-collection bag 7 is installed in liquid guiding cavity 61, and liquid-collection bag 7 includes liquid inlet 71, liquid inlet 71
It is connect with branch inlet tube 31.
As depicted in figs. 1 and 2, main separating tube 8 is bonded with 7 upper surface of liquid-collection bag, the both ends of main separating tube 8 respectively with primary
Slot 2 and secondary slot 4 are connected to, and one end of main separating tube 8 extends in standby liquid bath 42, are connected with branch separating tube on main separating tube 8
81, branch separating tube 81 is connect with liquid-collection bag 7, is connected with filter 9 on main inlet tube 8.
As shown in Figure 1, preferably, filter 9 is installed on portion of the main separating tube 8 between liquid guiding cavity 6 and secondary slot 4
Point.
As shown in Figure 3, wherein filter 9 includes outer cylinder 91 and the inner cylinder 92 that is sheathed in outer cylinder 91, inner cylinder 92 and outer
Cavity is constituted between cylinder 91, the water inlet end connecting with main separating tube 8 and water outlet, water inlet end and water outlet are offered on outer cylinder 91
It is connected to inner cylinder 92.
Wherein, water intake end is connected with an overflow pipe 93, and overflow pipe 93 is extended in inner cylinder 92 and do not contacted with inner cylinder 92, overflows
The periphery wall that flow tube 93 is located at 92 one end of inner cylinder offers the thread groove 93.1 of downward spiral arrangement, and one end of thread groove 93.1 is worn
Inner cylinder 92 is crossed to extend in the cavity between inner cylinder 92 and outer cylinder 91.
Wherein, the radial direction that overflow pipe 93 is located at one end in inner cylinder 92 is successively decreased from top to bottom, and overflow pipe 93 is located at inner cylinder 92
Strainer 93.2 is installed with the part at 91 cavity of outer cylinder.
Feed liquid enters the cavity between overflow pipe 93 and inner cylinder 92 from water inlet end, and feed liquid impact 92 bottom of inner cylinder forms reversed
Influent stream pressure does centrifugation eddy motion along the helicla flute 93.1 of 93 outer wall of overflow pipe, the different densities when feed liquid does centrifugal movement
It is separated between solid and liquid, solid particle does centrifugal movement and is extruded into helicla flute 93.1, and solid particle passes through spiral
It is precipitated in the cavity that slot 93.1 enters between inner cylinder 92 and outer cylinder 91 and by strainer 93.2, feed liquid is so far separated with impurity therein
Feed liquid flows to main separating tube 8.
Specifically, the autonomous inlet tube 3 of feed liquid enters in primary slot 2, the feed liquid after primary slot 2 fills feed liquid, in primary slot 2
Start to be flowed in main separating tube 8, while part feed liquid enters in the branch inlet tube 31 connecting with main inlet tube 3, and passes through branch
Inlet tube 31 pours into coupled liquid-collection bag 7 and lower liquid guiding cavity 62, the kickboard 62.2 being covered in junior's liquid guiding cavity 62
It is gradually risen with sliding rail feed liquid surface and starts to squeeze the liquid-collection bag 7 being located in upper liquid guiding cavity 61, after liquid-collection bag 7 is squeezed, collection
Feed liquid outflow in liquid bag 7, since branch inlet tube 31 constantly has feed liquid to pour into, the feed liquid of liquid-collection bag 7 can only be from branch separating tube 81
It is sent to main separating tube 8, feed liquid is gradually filled in main separating tube 8, feed liquid flows to it through filter 9 and is located at secondary slot later
4 one end and full standby liquid bath 42, as above see, the fixed end face between primary slot 2, liquid guiding cavity 6 and secondary slot 4 connects on the whole
Line is in deposition, i.e., height of the top end face of secondary slot 4 away from horizontal plane is lower than primary height of 2 top end face of slot away from horizontal plane, is above led
Sap cavity 61 is all larger than primary slot 2 with secondary slot 4 away from horizontal height away from horizontal height, and main separating tube 8 is from primary slot 2 through drain
For chamber to secondary slot 4, the part that main separating tube 8 is located at upper liquid guiding cavity 61 is located at highest point, primary slot 2 and the standby liquid in secondary slot 4
The full feed liquid of slot 42, the pressure that main separating tube 8 is located at 2 one end of primary slot are greater than it and are located in secondary slot 4 standby 42 one end of liquid bath
Pressure the feed liquid in primary slot 2 to be directed into standby liquid bath 42 automatically, due to standby height of the liquid bath 42 apart from horizontal plane
Degree is lower than height of 4 top end face of secondary slot apart from horizontal plane so that feed liquid can provide for oneself liquid bath 42 be spilled over in secondary slot 4 without
Feed liquid leakage occurs, final feed liquid is sprayed by the spray head 51 in secondary slot 4.
The above embodiments and description only illustrate the principle of the present invention and most preferred embodiment, is not departing from this
Under the premise of spirit and range, various changes and improvements may be made to the invention, these changes and improvements both fall within requirement and protect
In the scope of the invention of shield.
