8) it is solid product is defeated outside via conveyer 17, filter plate 20 to be cleaned is delivered to cleaning device 16 and is carried out clearly
Wash.
During practical application, the filter-pressing device 15 in the system could be provided as at least one, at least one filter-pressing device 15
Alternate run, so as to handle incessantly mud, to improve efficiency of press filtering.As shown in Fig. 1~Fig. 2, the pressure of the system
It is two to filter device 15, which connects respectively with feed inlet 12, liquid outlet 14, air inlet 11, drain 13
Connect, and the break-make of each pipeline is controlled by being arranged at least one solenoid valve 19 of system, to realize two filter-pressing devices
15 alternate run.For the specific control process of at least one filter-pressing device 15, the present embodiment just repeats no more.
It is the explanation to the structure of filter-pressing device 15 above, the structure of the cleaning device 16 of the application is said below
It is bright.
Referring to Fig. 1 and Fig. 3, the cleaning device 16 that the drilling mud of the application does not land processing system 10 includes：Spray is single
Member 165 and supply unit, supply unit align with discharge port 151, by filter plate 20 to be cleaned be delivered to spray unit 165 into
Row cleaning, and the conveying of filter plate 20 after cleaning is back to filter-pressing device 15.
Wherein, supply unit includes：Boom hoisting 162 and horizontally disposed first carrier chain 161, the second carrier chain
164 and the 3rd carrier chain 163.
First carrier chain 161, the second carrier chain 164, the 3rd carrier chain 16 3 and boom hoisting 162 drive by motor and control
System.
The type of boom hoisting 162 can be a variety of, and claw structure is arranged in the application, may tighten or loosen filter plate
20。
One end of first carrier chain 161 is located at the lower section of the cover 156, and is opened in the cover 156 to vertical shape
During state, first carrier chain 161 is located at the both sides of the filter plate 20 and is overlapped with the filter plate 20, to realize that described first is defeated
Chain 161 is sent to convey filter plate 20 to be cleaned；
