Description

High-efficient automatic mud-discharging press filter

Technical Field

The invention relates to the field of filter pressing equipment, in particular to a high-efficiency automatic mud-discharging filter press.

Background

The filter press is one of the common filter pressing devices, and is a mechanical device which applies a certain pressure to an object by utilizing a special filter medium so as to dialyze liquid, and is a common solid-liquid separation device. The preparation method is applied to chemical production in the beginning of the eighteenth century, and is still widely applied to industries such as chemical industry, pharmacy, metallurgy, dye, food, brewing, ceramic, environmental protection and the like. Especially, the sludge treatment in the environmental protection industry, most of the existing filter presses adopt a plate-frame filter pressing mode, namely, the pressing force applied to the filter pressing object, namely the sludge, is in the horizontal direction, in the preparation pressing stage, for example, the existing plate-frame drum filter press, the piston rod of the hydraulic cylinder directly acts on the filter plate to enable the filter plate to be closed and pressed and then pressed, but after the pressing is finished, the adjacent plates are required to be pulled apart for a certain distance, and because of the limitation of the length of the hydraulic cylinder, the filter plates are sequentially opened one by one through a plate opening mechanism, one filter press usually has thirty to fifty filter plates, the whole process of completely removing the sludge needs a long time, the efficiency is very low, if a plurality of filter plates are required to be pulled apart at one time, the length of the hydraulic cylinder is required to be lengthened due to the length of the piston rod, the length of the hydraulic cylinder is increased, the whole filter press is also increased, the occupied area is also increased, and the hydraulic cylinder is easily deformed after the length of the hydraulic cylinder is increased, and the sealing ring of the hydraulic cylinder is easy to cause leakage, so that in order to guarantee the stable running of equipment, and the general condition is in a short range. To solve the problem, the invention is named as a walking driving device for a filter plate of a filter press, and the patent with publication number of CN112190990A 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 two sides of the frame are provided with side beams; the side beam sleeving holes penetrate through the side beam sleeving holes, and rollers rolling on the side beams are arranged at the front end and the rear end of the upper side and the lower side of the side beam sleeving holes; the movable end plate is arranged on the side beam, and the movable end plate is arranged on the side beam. The hydraulic driving mechanism and the roller rotating device are arranged on the driving support, in the pressing process, the roller is rotated to walk for a long distance in advance, the side beam is fixed by the positioning bolt, and the hydraulic mechanism is started to press the filter plate again. Although the stroke of the filter plate is increased, the disadvantage is 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 excessively large due to the limitation of equipment size, the volume of a driving motor of the roller rotating device is limited, and the power of the driving motor is further limited, so that the thrust is influenced, and the thrust is small, so that the whole filter plate is pushed. In addition, the roller wheel rotating guide depends on the sleeve joint hole of the side beam, the accuracy is difficult to control accurately, if the size of the roller wheel is smaller, the friction force of the roller wheel is large, the obstruction is easy to cause, if the size of the roller wheel is larger, the roller wheel rotating thrust is uneven, the roller wheel is easy to deflect or block, and meanwhile, the unbalanced thrust of the filter plate is easy to deviate. Moreover, the positioning bolts are difficult to control to accurately enter the side beam positioning holes, so that the positioning bolts can be realized, the required precision is high, other more auxiliary facilities are needed, the equipment is complicated, the cost is higher, the equipment is easy to break down, the reverse thrust of the hydraulic driving mechanism in the process of squeezing the filter plates is huge again, and the bearing capacity of the positioning bolts is difficult to ensure.

According to current sludge treatment technique, the pressure filter is at the board in-process of unloading mud of opening, and some mud contains organic component very high, and the filter cake of formation bonds on the filter cloth of filter chamber easily, can only dismantle with the iron through the manual work at present, and is consuming time hard, inefficiency.

As shown in fig. 1-25, the working process of the efficient automatic mud-pressure filter of the invention is as follows: firstly, in the board closing process, preparation of a pressed filter cake is performed under the control of a circuit control system, a speed reduction motor 116 is started to drive a speed reduction motor shaft 114 to rotate, at the moment, a main shaft clutch 409 is in a leaving state, and a driving wheel 406 rotates along with the speed reduction 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 mobile hydraulic platform 300 starts to move along with the extension plate 404 from the front end seat 102 to the thrust seat 103, and at this time, the movable push plate 110 is pushed to squeeze each filter plate in the filter plate array 201. When the mobile hydraulic platform 300 reaches the vicinity of the limiting plate 309, at this time, a signal is detected by a sensing switch mounted on the inner side surface of the side beam 104 or on the mobile hydraulic platform 300, the circuit control system sends a stop signal to stop the operation of the gear motor 116, the linkage clutches 410a and 410b are separated, the main push hydraulic pump 302 on the mobile hydraulic platform 300 is started, the switching 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 plate 308 approaches the inner side surface of the side beam 104 and approaches the limiting plate 309 (at this time, the locking plate 308 is positioned between the movable push plate 110 and the limiting plate 309). Subsequently, the hydraulic oil path of the switching valve 313 leads to the main pushing hydraulic pump 302, the main piston rod 304 pushes the movable push plate 110, and the movable hydraulic platform 300 is retracted due to the reaction force, so that the locking plate 308 contacts with the limiting plate 309 to stop the movement of the movable hydraulic platform 300 and lock the movable hydraulic platform, and the filter plates in the filter plate array 201 are strongly pressed. The outside mud is input into a filtering chamber with filter cloth around the filtering plate, and a series of operations such as tympanic membrane squeezing are carried out through a diaphragm, and a dried mud cake exists between the two annular filter cloths.
