Description
The application is the divisional application of application number 201310721640.7, December 18 2013 applying date, denomination of invention " filter press sludge dehydration device and automatic pulling plate method ".
Technical field
The present invention relates to field of sludge treatment, the automatic pulling plate method of a kind of filter press sludge dewatering specifically.
Background technology
A large amount of mud is produced in sewage treatment process, its quantity accounts for the 0.3%-0.5% of the process water yield, the process investment of mud and running cost are very huge, and the expense for sludge treatment generally accounts for the 20%-50% of sewage work's working cost, brings white elephant to sewage disposal.Current traditional treatment process first nurses one's health by adding flocculation agent, then belt filter press carries out mechanical dehydration, landfill, fermentation composting etc. are carried out in the mud outward transport forming water ratio about 70%-80%, and this mode brings extremely adverse influence because the too high surrounding enviroment to landfill yard of water ratio extremely process.Present application plate-and-frame filter press carries out mechanical dehydration method and gets more and more, and mud generally can reach water ratio about 60% and transport outward, and more traditional treatment process is greatly improved.But along with the minimizing of national sludge treatment and utilizationization require more and more higher, wishes that the moisture percentage in sewage sludge of process reduces further.
All cannot be extruded by the method for mechanical dehydration because biological cells in sludge and colloid contain a large amount of interstitial water (account for all moisture 70%).So, special means must be adopted to crack the viscose glue phase region of intercellular structure and mud, part " interstitial water " is first discharged, then is extruded by the method for machinery.By this combined innovation method, sludge dewatering can be realized to about 50%.
Plate pulling device in the automatic pulling plate system plate-and-frame filter press of plate-and-frame filter press, the quality of its performance directly has influence on the efficiency of plate-and-frame filter press and the efficiency of dehydration.Existing automatic pulling plate system is generally made up of motor, oil motor, pulling car, sprocket wheel, chain etc., under the control of rly., driven by motor oil motor, completed by chain-driving left and right pulling car and get arm-tie, it moves to get at every turn and draws one block of plate, after moving one block of plate to corresponding position, repeat to get one block of plate of leaving behind, till pulling whole sheet frames.This arm-tie method is little for impact the few small-sized plate-and-frame filter press of sheet frame quantity, but for the large-scale plate-and-frame filter press that sheet frame quantity is a lot, all sheet frames are all pulled, needs a lot of time, about probably needing half an hour as all pulled by the sheet frame of 100 polyliths, account for the whole sludge dewatering by plate-frame time large percentage of (about 2 hours), automatic pulling plate system has material impact for board and frame machine production efficiency.
Summary of the invention
The present invention is directed to current sludge dewatering and automatic pulling plate apparatus and method Problems existing, provide a kind of and can get the combination sludge dehydration device and method that draw plurality of plates simultaneously, moisture percentage in sewage sludge can be reduced, and improve the production efficiency of board and frame machine.
Automatic pulling plate method of the present invention, it comprises following steps:
1) before getting arm-tie, pulling block is positioned at below sheet frame, and lifting gantry rises under the effect of stepper-motor, screw mandrel and nut, and pulling block slowly enters into certain depth in sheet frame, and contacts with the ear that draws on sheet frame, and the altitude signal of rising is sent to controller;
2) controller sends signal to motor after the height that pulling block rising reaches certain being detected, driven by motor rollers roll, travel rope I on cylinder applies pulling force by tackleblock to rightmost pulling block, pulling block is pulled to move, pulling block drives first sheet frame motion, pulling block drives and determines connecting rod I simultaneously, determine connecting rod II and dynamic link work stretching, extension, when determining connecting rod I, determine connecting rod II and dynamic connecting rod extend to they line when being in ultimate range, distance between two sheet frames also reaches maximum, mud can fall completely, now second piece of arm-tie starts the pulling force being subject to connecting rod, pull second piece of sheet frame motion, so carry out successively, the sheet frame pulled required for this cycle is all pulled open a substantially equal distance, mud in sheet frame can be able to all drop,
3) after by the pull distance detecting travel rope I, controller judges that all sheet frames all pull open, signal is sent to left end oil cylinder, left end oil cylinder is by promoting a sheet frame on last (left side), sheet frame is drawn close toward first piece of sheet frame successively together, now, pull bar can shrink automatically, makes can be close between each sheet frame;
4) when all within this cycle sheet frames are all shifted onto, this Time Controller control step motor does reversing motion, and stepper-motor drives screw mandrel, nut makes lifting gantry decline, pulling block also along with under be reduced to the height that sheet frame draws ear;
5) controller signals to power set, power set controls travel rope II and is moved toward left end by whole plate pulling device, at travel rope II by whole plate pulling device toward in the process of left end movement, the oil cylinder of right-hand member shifts all pulling blocks onto high order end, enter into next cycle and pull next batch sheet frame, till all being pulled open by whole sheet frame, terminate all processes.
Adopt this automatic pulling plate method, pull multiple sheet frame simultaneously, under the coordinative role of each topworks and Controlling System, greatly improve arm-tie speed, shorten the whole arm-tie time, enhance productivity.
