Description
Technical field
The utility model relates to a kind of center transmission thickener that slip concentrates that is used for.
Background technology
Thickener is a kind of slip concentrator, when prodelta clay poly-precipitum in pond is too much, when the resistance of the rake frame of mud-scraping apparatus surpasses the transmission device ability, can cause the rake accident of pressing.Existing center transmission thickener adopts electric-motor drive, and what the measurement of rake frame change in resistance was adopted is mechanical sensor, and the resistance of rake frame is converted to displacement, again displacement is converted to the signal of telecommunication, in order to the action of control automatic rake-lifting system.This method complexity, easy break-down, poor reliability, versatility is poor.Putting forward the rake mode is to have to carry to carry rake, promptly harrows frame and promotes in rotation.At this moment it is bigger to harrow the suffered resistance of frame, acts between feather key and the keyway.Feather key is relative with keyway during lifting slides, and produces bigger friction, very easily with key and keyway contact surface plucking, makes the friction that rubs between paying more and more big, carries rake and becomes difficult, even damage and carry the parts of harrowing mechanism.
Summary of the invention
The purpose of this utility model is that a kind of center transmission thickener will be provided, and the measurement of the rake frame change in resistance of this machine is simple, can realize that off-load carries rake.
The purpose of this utility model is achieved in that this center transmission thickener comprises walking bridge, stationary magazine creel, goes into barrel, pan feeding pipeline, rake frame, power transmission shaft, controller for electric consumption, walk the bridge center and be connected with fluid pressure drive device, fluid pressure drive device is connected with power transmission shaft, the power transmission shaft lower end is connected with the rake frame, rake lifting device links to each other with power transmission shaft, and fluid pressure drive device and rake lifting device provide power by the Hydraulic Station of hydraulic system.
Described hydraulic system is that screen pack is positioned at fuel tank, the oil return opening of the oil return opening of hydraulic motor, the oil-in of oil pump, oil cylinder is connected to fuel tank, oil pump, magnetic valve, pressure switch and choke valve link to each other with oil supply loop, and magnetic valve links to each other with hydraulic motor, and choke valve links to each other with oil cylinder.
Integrated package of the common formation of described magnetic valve and pressure switch and overflow valve and electro connecting pressure gauge.
The utility model adopts hydraulic-driven, replaces motor-driven, is easy to realize automatic control, finishes the measurement and the transformation of signal with a pressure switch, and signal measurement is simple and easy to do, is subjected to external interference few, accurately and reliably.Manufacturing, use, easy maintenance, expense is low.Provide precondition for adopting off-load to put forward the rake technology.When rake hydraulic motor instantaneous stop is carried in off-load, drives the oil circuit off-load, and the bounce-back of rake frame forms certain interval between key and keyway, between friction is paid friction reduce to very little, thereby make automatic rake-lifting be able to smooth realization.The enterprise such as coal washing, ore dressing that is suitable for as open work uses as the slip concentrator.
Below in conjunction with drawings and Examples the utility model is elaborated.

The specific embodiment
In Fig. 1 and Fig. 2, walk bridge 1 center and be connected with fluid pressure drive device 2, fluid pressure drive device 2 is connected with power transmission shaft 9, and power transmission shaft 9 lower ends are connected with rake frame 8, rake lifting device 2-1 links to each other with power transmission shaft 9, and fluid pressure drive device 2 and rake lifting device 2-1 provide power by the Hydraulic Station 11 of hydraulic system.
In Fig. 3, screen pack 26 is positioned at fuel tank 12.The oil return opening of the oil cylinder 19 among the oil return opening of the hydraulic motor 23 in the fluid pressure drive device 2, the oil-in of oil pump 15, the rake lifting device 2-1 is connected to fuel tank 12.Oil pump 15, magnetic valve 22, pressure switch 18 and choke valve 20 link to each other with oil supply loop.Magnetic valve 22 links to each other with hydraulic motor 23 in the fluid pressure drive device 2.Choke valve 20 links to each other with oil cylinder 19 among the rake lifting device 2-1.
The oil-out place of oil pump 15 is connected with overflow valve 24, electro connecting pressure gauge 17.Magnetic valve 22, pressure switch 18, overflow valve 24, electro connecting pressure gauge 17 constitute integrated package 21.
Hydraulic system adopts combination hydraulic station 11, carries rake for hydraulic-driven and hydraulic pressure power is provided.The oil pump 15 that Hydraulic Station 11 is selected for use is a unidirectional variable pump.
Fluid pressure drive device 2 is selected two hydraulic motors 23 with the reductor one for use, and hydraulic motor 23 drives the pivoting support of thickeners by two travelling gears and is fixed on rake frame 8 rotations on the pivoting support, finishes and scrapes the mud action.
