Background

The filter press is one of the commonly used filter press devices, and is a mechanical device which applies a certain pressure to a target by using a special filter medium to dialyze liquid, and is a commonly used solid-liquid separation device. The method is applied to chemical production at the beginning of the eighteenth century, and is still widely applied to industries such as chemical industry, pharmacy, metallurgy, dye, food, brewing, ceramics, environmental protection and the like until now. Particularly, in the sludge treatment in the environmental protection industry, most of the existing filter presses adopt a plate-frame type filter pressing mode, that is, the pressing force applied to sludge which is a filter pressing object is in a horizontal direction, in the initial preparation of the pressing stage, like the existing plate-frame type tympanic membrane filter press, the filter plates are directly acted by piston rods of hydraulic cylinders to be closed and pressed, and then pressing is performed, but unloading (mud removal or cake removal) after pressing is completed needs to pull apart adjacent plates for a certain distance, because of the limitation of the length of the hydraulic cylinders, the filter plates are opened and unloaded one by a plate opening mechanism at present, thirty to fifty filter plates are often required for complete mud removal, a long time is needed for complete mud removal, the efficiency is very low, if a plurality of filter plates are pulled apart at one time, the pulling-apart degree between the filter plates is determined by the length of the piston rods, the length of the hydraulic cylinders needs to be lengthened, the length of the whole filter press is increased due to increase the occupied area, and the hydraulic cylinders are suspended horizontally, the weight of the hydraulic cylinders is also increased, the deformation of the cylinder is easy to cause the leakage, so as to ensure the stable operation of the hydraulic cylinders, and the general limited length of the hydraulic cylinders, the equipment, the general limited range of the equipment is limited length. To solve the problem, the Chinese national patent office publishes a 'walking driving device for a filter plate of a filter press', and the publication number is 'CN 112190990A', and the walking driving device comprises a frame, wherein one end of the frame is provided with a fixed end plate, and the other end of the frame is provided with a movable end plate; a plurality of filter plates are arranged between the fixed end plate and the movable end plate; and side beams are arranged on two sides of the frame; the driving support is arranged on the rack, two sides of the driving support are provided with side beam sleeving holes, the side beams penetrate through the side beam sleeving holes, and the front end and the rear end of the upper side and the rear end of the lower side of each side beam sleeving hole are provided with rollers rolling on the side beams; the driving support is internally provided with a hydraulic driving mechanism for driving the roller to rotate, and the roller runs on the side beam when rotating, so that the movable end plate is driven to move, and the filter plates are driven to be pressed together or separated from each other. According to the hydraulic filter pressing device, a hydraulic driving mechanism and a roller rotating device are arranged on a driving support, in the pressing process, after the roller rotates to walk for a long distance in advance, a positioning bolt locks a side beam, and then the hydraulic mechanism is started to press a filter plate again. Although the stroke of the filter plate is increased, the defects are that the roller rotating device is arranged on the driving bracket, the weight of the driving bracket is increased, the energy consumption is increased, the roller rotating device is not suitable to be overlarge due to the limited size of the equipment, the volume of a driving motor is limited, the power of the driving motor is limited, the thrust is influenced, and the pushing of the whole filter plate is influenced due to the small thrust. In addition, the guide of the rotation of the roller depends on the sleeving hole of the side beam, the precision is difficult to control accurately, if the size of the roller is smaller, the friction force of the roller is large, and the roller is easy to obstruct, if the size of the roller is larger, the self deflection or the blocking is easy to cause because the thrust of the rotation of the roller is uneven, and meanwhile, the deviation is easy to cause the unbalanced thrust of the filter plate. And moreover, the positioning bolt is difficult to control to accurately enter the positioning hole of the side beam, even if the positioning bolt can be realized, the required precision is very high, other more auxiliary facilities are needed, the equipment is complicated, the cost is higher, the fault is easy to occur, the reverse thrust of the hydraulic driving mechanism is very large in the process of squeezing the filter plate, and the bearing capacity of the positioning bolt is difficult to guarantee.

Referring to fig. 1-25, the filter press with filter plates fully disassembled and automatically stripped of filter cake according to the present invention generally operates as follows: firstly, preparing for squeezing filter cakes in a plate closing process under the control of a circuit control system, starting a speed reducing motor 116 to drive a speed reducing motor shaft 114 to rotate, wherein a main shaft clutch 409 is in a leaving state at the moment, and a driving wheel 406 rotates along with the speed reducing motor shaft 114; as shown in fig. 4, the driven wheel 407 is driven to rotate by the linkage chain 408, the linkage clutches 410a and 410b are closed, the driven wheel 407 drives the traction through shaft 405 to rotate, and the traction through shaft 405 drives the first traction wheel 401 to rotate; as shown in fig. 5, the first traction wheel 401 drives the second traction wheel 402 to rotate through the traction belt 403, and simultaneously drives the extension plate 404 to move, the movable hydraulic platform 300 follows the extension plate 404 to move from the front end seat 102 to the thrust seat 103, and at this time, the movable push plate 110 is pushed to push each filter plate in the filter plate array 201 to be squeezed together. When the movable hydraulic platform 300 reaches the position-limiting plate 309, and the inductive switch mounted on the inner side surface of the side beam 104 or the movable hydraulic platform 300 detects a signal, the circuit control system sends a signal that the speed-reducing motor 116 stops working, the linkage clutches 410a and 410b leave to start the main push hydraulic pump 302 on the movable hydraulic platform 300, the change-over valve 313 leads the hydraulic oil path to the locking hydraulic cylinder 307 (see fig. 10), the piston rod of the locking hydraulic cylinder 307 pushes the locking plate 308 to pop out from the locking sleeve holes 306 on both sides, and the front end of the locking hydraulic cylinder pushes the inner side surface of the side beam 104 and approaches the position-limiting plate 309 (at this time, the locking plate 308 is located between the movable push plate 110 and the position-limiting plate 309). Subsequently, the hydraulic oil path of the switching valve 313 leads to the main push hydraulic pump 302, the main piston rod 304 pushes the movable push plate 110, the movable hydraulic platform 300 retracts due to the reaction force, the locking plate 308 contacts with the limiting plate 309, the movable hydraulic platform 300 stops moving and is locked, and the filter plates in the filter plate array 201 are pressed strongly. The external slurry is input into a filter chamber containing filter cloth at the periphery between filter plates, a series of operations such as tympanic membrane squeezing and the like are carried out through a diaphragm, and a dried mud cake exists between two annular filter cloth. In the second step, the plate opening process, i.e. the process of opening the filter plates in the filter plate array 201, is the reverse of the above first step, the main piston rod 304 pulls the movable push plate 110 back (connected by the main piston rod 304), the main piston rod 304 retracts into the main push hydraulic cylinder 303, the filter plates in the filter plate array 201 start to loosen and are pulled apart from each other by a small distance, the lock plate 308 retracts and is separated from the limit plate 309, under the action of the pulling mechanism, the movable hydraulic platform 300 follows the extension plate 404 and moves from the thrust seat 103 to the front end seat 102 until the front end seat 102, at this time, the filter plates in the filter plate array 201 are pulled apart by a large distance (20 to 30cm) under the connection of the push-pull rod 113, and all the independent feeder suspensions 600 are kept at the middle positions between the filter plates a203a and the filter plates B203B of each filter plate unit 202. And a third step, in the mud removing process, the reducing motor shaft 114 is started (the power is shared with the power of the traction mechanism), the linkage clutches 410a and 410b are separated, the main shaft clutch 409 is closed, the reducing motor shaft 114 rotates, gears on the square rod coupling 108 are engaged and driven to rotate through an additional gear box (not shown in the figure), gears on square rod reversing seats 105 at two ends rotate along with the gears and drive two square rods 107 to rotate, square shaft sliding wheels 515, dial wheels 513, upper supporting shafts 507 and upper supporting wheels 509 are sequentially driven to rotate, two stripping rods 520 staying above the upper supporting shafts 507 of the filter plates and below the lower supporting shafts 508 are driven to move reversely along the front and the back of the filter plates through synchronous movement of stripping chains 516 at two sides of the filter plates, the annular filter cloth 512 penetrates through stripping gaps 521 of the stripping rods 520, so that mud cakes attached to the annular filter cloth 512 are separated from the annular filter cloth, and gas or liquid input from the outside into injection channels 524 in the stripping rods is sprayed to the surface of the annular filter cloth 512 through a plurality of micropores on the surface of the annular filter cloth 512 to perform scanning residue or cleaning. After stripping and cleaning, the stripping gap 521 returns to the original position to wait for the next cycle of operation of the equipment.
