[0030] In combination Figure 6 As shown, the device is placed in a waste liquid environment, the waste liquid environment forms a floating oil layer 501, a liquid layer 502 and a sediment layer 503 from top to bottom, the liquid suction pipe 10 has a certain length, and the floating plate 20 and the shell 30 are arranged on the upper part and the lower part of the liquid suction pipe 10 respectively, so that after the shell 30 enters the liquid layer 502, it floats on the liquid surface by the buoyancy of the floating plate 20, and the whole device forms a liquid passage through the combination of the above-mentioned components, the liquid passage specifically comprises the vertical holes 320, the liquid storage groove 311, the through hole 3120, the side hole 102, the middle cavity 100 and the opening 101, and the liquid suction pump is connected with the opening 101 to perform a liquid suction action. At the initial stage, the liquid in the liquid layer 502 enters the liquid storage groove 311 through the vertical holes 320, and can enter the middle cavity 100 through the through hole 3120 and the side hole 102, when the liquid suction pump works, the negative pressure generated will suck the liquid in the middle cavity 100 out of the opening 101, and continuously transport the liquid in the liquid layer 502 through the above-mentioned liquid passage, to complete the suction and recovery of the liquid in the liquid layer 502; at the same time, since the filter layer covers the vertical holes 320, impurity particles can also be prevented from entering the liquid passage, to ensure the quality of liquid recovery. It should be noted that even in the initial stage when the device is placed in the waste liquid environment, the shell 30 itself also has a buoyancy to prevent the shell 30 from entering the liquid layer 502, but it can be immersed in the liquid layer 502 by manual operation (pressing down), and after the liquid enters the shell 30, the weight of the shell 30 is increased to keep it in the liquid layer 502, and the dynamic balance is maintained by the buoyancy of the floating plate 20.

[0031] The liquid passage (vertical hole 320, liquid storage groove 311, through hole 3120, side hole 102, middle cavity 100, opening 101) formed by the device can quickly suck and recover the liquid in the liquid layer 502, and the liquid can be filtered through the filter layer, which not only ensures the efficiency of liquid recovery, but also avoids the suction of impurities, thereby improving the quality of liquid recovery.

[0032] In addition, the side hole 102 is provided with a plurality of through holes 3120, which can ensure the flow rate and flow velocity of the liquid passage.

[0033] Preferably, the upper end of the upper shell 32 is formed with a positioning groove 322, and the filter layer 40 is embedded in the positioning groove 322, so as to ensure the installation stability of the filter layer 40. In addition, an annular baffle 3221 extending horizontally into the positioning groove 322 can be arranged at the upper end of the upper shell 32, so as to avoid the upward relative movement of the filter layer 40 out of the positioning groove 322 and the vertical hole 320, and ensure that the filter layer 40 can always cover the vertical hole 320. In addition, the filter layer 40 has the characteristics of extrudable deformation, and the above-mentioned arrangement does not affect the removal of the filter layer 40 from the positioning groove 322 and the upper sleeve 321, and the filter layer 40 can be conveniently removed for cleaning.

[0034] Further, the liquid inlet hole (not shown) can be arranged on the side wall of the positioning groove 322 (i.e. on the side wall of the upper shell 32) and horizontally penetrates the upper shell 32, so that the liquid can not only enter through the upper end of the filter layer 40, but also enter through the side wall of the filter layer after passing through the liquid inlet hole, thereby improving the liquid inlet path and increasing the liquid inlet amount.

[0035] The inner side wall of the upper sleeve 321 and / or the lower sleeve 312 is provided with an internal thread, and the outer side wall of the liquid suction pipe 10 located above the side hole 102 is provided with an external thread 12. The shell 30 is screwed on the liquid suction pipe 10. Preferably, the internal thread 3211 is arranged on the inner side wall of the upper sleeve 321, and the cooperation between the internal thread 3211 and the external thread 12 can realize the adjustment of the height position of the shell 30 on the liquid suction pipe 10. Correspondingly, the opening area of the through hole 3120 needs to be larger than that of the side hole 102, that is, the through hole 3120 needs to have a certain extension in height and a certain extension in width. When the shell 30 and the liquid suction pipe 10 are connected by rotation, the through hole 3120 can always be in communication with the side hole 102.

[0036] In order to avoid the liquid level in the liquid layer 502 from being continuously reduced after the liquid is continuously absorbed, the lower end of the shell 30 abuts against the sediment layer 503, the lower sleeve 312 can be arranged to penetrate the bottom shell 31, the lower part of the liquid suction pipe 10 extends out of the lower sleeve 312, and the part of the liquid suction pipe 10 protruding from the lower end of the shell 30 is used for supporting and limiting.

[0037] As Figure 5 shown, in another embodiment of the present application, the lower sleeve 3121 does not penetrate the bottom shell 31, the lower end of the lower sleeve 312 (the bottom shell 31) is sealed, but a limiting block 33 extending downward is arranged at the lower end of the bottom shell 31, the limiting block 33 can also achieve the supporting and limiting effect, and the sealed bottom shell 31 has better sealing effect.

[0038] As Figure 5 shown, the lower part of the upper shell 32 is embedded in the upper part of the liquid storage groove 311 and is screwed with the bottom shell 31, specifically, the lower end of the outer side wall of the upper shell 32 is provided with a lower thread 32a, the side wall of the upper end of the liquid storage groove 311 is provided with an upper thread 31a, the connection between the upper shell 32 and the bottom shell 31 is achieved through the screwing of the lower thread 32a and the upper thread 31a, this arrangement can realize the disassembly of the upper shell 32 and the bottom shell 31, and the upper shell 32 and the bottom shell 31 can be opened after the device is used for a period of time, so as to clean the inside of the liquid storage groove 311.
