Embodiment 1
[0021] As shown in accompanying drawing 1, it is the structural representation of intelligent central transmission single-pipe dredger of the present invention, and this intelligent central transmission single-pipe dredger is provided with driving mechanism 2, rotating cage 4, collecting tank 13 places. The mud tank 5, the truss 6, the mud suction pipe 7, the mud discharge pipe 14, the mud discharge valve 11, the electric actuator 10, the sludge concentration signal acquisition device 8 and the controller 9, wherein the driving mechanism 2 is set in the middle of the sedimentation tank 13 At the top of the center column 3, the tumbler 4 is set on the outer periphery of the center column 3, and the mud collection tube 5 is set on the center column 3 at the bottom of the tumbler 4, which is connected to the mud suction pipe 7, and the fan-shaped well and the mud discharge pipe 14 are passed inside. Communication, the mud discharge pipe 14 communicates with the mud discharge well ...
Embodiment 2
[0033] The structure of the intelligent central drive single-pipe dredger in this embodiment is the same as that in Embodiment 1, and will not be repeated here. The difference lies in the control mode of the controller. Specifically, in this embodiment, two concentration values C are selected according to the control range of the sludge concentration required by the system. 1 、C 2 (C 1 >C 2 ), respectively as the upper limit and the lower limit of the control range, the sludge concentration signal value C collected by the sludge concentration signal acquisition device 8 is respectively compared with the upper limit value C 1 and the lower limit C 2 Comparison, control the opening of the sludge discharge valve 11 according to the comparison result, and control the electric actuator to adjust the opening of the sludge discharge valve when the sludge concentration signal value C is located at the concentration upper limit value C 1 and the concentration lower limit C 2 rem...
Embodiment 3
[0041] The structure of the intelligent central drive single-pipe dredger in this embodiment is the same as that in Embodiment 1, and will not be repeated here. The difference lies in the control mode of the controller. Specifically, in this embodiment, two concentration values C are selected according to the control range of the sludge concentration required by the system. 1 、C 2 (C 1 >C 2 ), respectively as the upper limit and lower limit of the control range, and at the same time in order to increase the safety of the system, increase the concentration upper limit alarm value C max and concentration lower limit alarm value C min , the sludge concentration signal value C collected by the sludge concentration signal acquisition device 8 is respectively compared with C 1 、C 2 、C max and C min , compare, and determine the opening degree of the mud discharge valve 11 according to the comparison result, and determine whether to activate the alarm signal at the same time....
