as shown in fig. 3 and 4, two end faces of the filter press plate 104 are respectively provided with a filter membrane 201, 202; one side of each filtering membrane close to the outside is a first side, and one side close to the inside is a second side; the filter membrane surface having a plurality of filter pores allowing filtrate to pass from the first side of the filter membrane to the second side; after the two filter pressing plates 104 are combined, a filter cavity 108 is formed on the first sides of the two opposite filter membranes;
two end faces of the pressure filter plate 104 are respectively provided with a plate shoulder 204; the plate shoulder 204 is made of a compressible material; the plate shoulder 204 forms a complete circle; the maximum distance D between the plate shoulders 204 on the two end surfaces is larger than the distance D between the two filter membranes on the two end surfaces; after the plate shoulders 204 of the two filter pressing plates 104 are combined in a contact mode, a filter cavity is formed in an enclosing mode;
each of the filter press plates 104 includes at least one inlet hole 203; the feed hole 203 is used for connecting an ore pulp conveying pipeline and enabling ore pulp to enter the filter cavity for filter pressing;
the moisture measuring module comprises a microwave generator 301, a transmitting end 302, a receiving end 303, a processing module and a communication module (not marked on the figure); the processing module is electrically connected with the microwave generator 301, the transmitting end 302, the receiving end 303 and the communication module; the microwave generator 301 is used for generating a microwave signal with specified power and frequency, and directionally transmitting the microwave signal through the transmitting end 302; the receiving end 303 is configured to receive and process the microwave signal sent by the transmitting end 302, and feed back acquired signal data to the processing module; the processing module controls the microwave generator 301 to work, and after the feedback signal of the receiving end 303 is processed digitally, the feedback signal is output to the control system through the communication module; the communication module is connected with the control system in a wireless communication mode, receives a control instruction of the control system and is used for controlling the moisture measurement module to work;
the launching end 302 is located on a first side of one of the filter membranes of the filter press plates 104; the transmitting end 302 is protected by a protective shell and protrudes out of the filter membrane; the receiving end 303 is located on the other side of the filter pressing plate 104 opposite to the transmitting end 302; the transmitting end 302 and the receiving end 303 of the two filter press plates 104 are paired and a predetermined measurement distance is maintained therebetween.
The transmitting end 302 moves through a moving mechanism to adjust the measuring distance;
the control system controls the duration of the starting compression stroke of the driving device 103 of the supercharging device according to the water content data of the filter residue measured by the water content measuring module, and controls the moving mechanism of the transmitting end 302 to adjust the measuring distance;
in a filter pressing preparation stage, the control system adjusts the distance between a plurality of filter pressing plates 104 to ensure that the plate shoulder 204 of each filter pressing plate 104 just contacts; slurry is conveyed into the pressure tank 101 through an external high-pressure pump and is guided to the feeding hole 203 through a pipeline; slurry flows through the plurality of feed holes 203 into the plurality of filter press chambers 108; due to the positive pressure in the input pipeline, the ore pulp continuously presses the filter membranes on the two sides after entering the filter pressing cavity 108 and extrudes the filtrate in the filter pressing cavity; filtrate passes through the filter membrane into the drainage channels of the helical compression bar 102 and exits through valve 105 into a collection tank;
after the filter pressing process is carried out for a period of time, the pressure in the pressure tank 101 reaches a stable maximum value, and the output of the filtrate is reduced; at this point the compression stroke is started: pushing out and embedding the telescopic positioning pins 205 on the plurality of filter pressing plates 104 into the chutes 107; due to the locking action of the telescoping dowel pins 205 and the central threaded hole 206 of the press plate 104, the press plate 104 cannot freely rotate about the helical compression rod 102;
further, the helical compression rod 102 is driven by the driving device 103 to rotate, and the plurality of filter press plates 104 will move axially and further close due to the screw action of the central threaded hole to generate stronger pressure; meanwhile, after the plate shoulder 204 is gradually compressed due to the axial pressure, the volume of the filter pressing cavity 108 is also compressed at the same time, so that the water content of the filter residue in the filter pressing cavity 108 is reduced;
further, when the shoulder 204 is compressed to a certain limit, the retractable positioning pin 205 on the filter press plate 104 is pulled back, and the filter press plate 104 can rotate along with the rotation of the spiral compression rod 102; as shown in fig. 1, starting from the filter pressing plate 104 at the farthest end in the compression direction, each filter pressing plate 104 is sequentially operated to pull back the telescopic positioning pin 205, so that the compression stroke is completed, and the maximum filter pressing effect is achieved.
Example two:
this embodiment should be understood to include at least all of the features of any of the foregoing embodiments and further modifications thereon;
in the compression stroke of the filter pressing system, as the plate shoulder 204 needs to be compressed with stronger pressure, the pressure reaches 4 to 5Mpa and is kept for a period of time, so that the excessive loss of the plate shoulder 204 is easily caused; meanwhile, the total duration of the filter pressing process is directly influenced by the duration of the pressure maintaining time, so that the whole filter pressing process is further optimized by measuring the water content of the filter residue by adopting the water content measuring module;
the moisture measuring module can measure the moisture content in the filter residue in a non-contact manner by utilizing a high-frequency microwave principle; the microwave is a high-frequency electromagnetic wave, and the attenuation and phase change generated when the microwave transmits through a medium are mainly determined by the dielectric constant and the dielectric loss tangent value of the medium; water is a polar molecule, and the dielectric constant and the dielectric loss tangent value of the water are far higher than those of common media; the dielectric constant and the loss tangent of the water-containing medium, such as filter residue in the technical scheme, are mainly determined by the water content of the water-containing medium; the microwave is emitted from the emitting end 302, passes through the filter cavity and the filter residue therein, and is received by the receiving end 303 which is in the same straight line and opposite position with the emitting end 302; according to the attenuation of the microwave power and the change of the phase shift, the water content in the filter residue can be calculated;
further, the filter press plate 104 needs to be adjusted at multiple positions during the whole filter press process, so that the distance between the transmitting end 302 and the receiving end 303 may affect the measurement value of the moisture measuring module based on the unified evaluation standard, and therefore, the transmitting end 302 includes the moving mechanism capable of moving along the axial direction to adjust the distance between the transmitting end 302 and the receiving end 303;
as shown in fig. 6, the rear side of the transmitting end 302 is supported by the damping elastic member 304 and reaches the shortest measurement distance in a free state; the rear side of the transmitting end 302 comprises a magnet 306; the magnet 306 is in contact with the damping elastic element 304; the damping elastic element 304 is preferably a precision sprung magnetic spring; the damping elastic element 304 has a uniform elastic coefficient, and the compression ratio is in direct proportion to the stress; a first end of the damping elastic element 304 is in contact with the emitting end 302; a second end of the damping elastic element 304 is in contact with the electromagnetic switch 305; the electromagnetic switch 305 generates an electromagnetic field with controllable magnetic field intensity in the power-on state and adsorbs the magnet; the voltage control of the electromagnetic switch 305 can control the magnetic field intensity, so that the distance between the transmitting end 302 and the receiving end 303 can be adjusted; further, the outermost side of the hair end and the receiving end 303 is protected by high-strength glass 307, so that filter residues are prevented from entering to influence the measurement effect;
further, in a filter pressing preparation stage, the plate shoulders 204 of the two filter pressing plates 104 just contact, at this time, the moisture measurement module is started to perform initial measurement, and after the voltage of the electromagnetic switch 305 is set as a standard voltage U, whether the current measurement value is stable is approved; when entering a filter pressing stage, due to the influence of filter residues and the change of the measurement distance, the measurement distance is adjusted to carry out adaptive adjustment on the unstable measurement condition which possibly occurs, so that the measurement value is stable and consistent as much as possible.
Example three:
this embodiment should be understood to include at least all of the features of any of the embodiments described above and further refinements thereto:
since the filter press plate 104 is disposed inside the pressure tank 101, it cannot be prevented from rotating by an external mechanical structure; meanwhile, the pressure tank 101 and the pressure plates 104 have small spaces therebetween, and only a small-sized stop mechanism is suitable for preventing the pressure plates 104 from rotating; therefore, the telescopic positioning pin mechanism is matched with the chute 107 to stop the filter pressing plate 104;
the telescopic positioning pin 205 is shown in fig. 7 and comprises a bolt 401, a driving gear 402, a driving shaft 403, a rack 404, a positioning hole 405 and a sealing shell 406; the sealing shell 406 is used for protecting the parts from mechanical abrasion and chemical corrosion caused by direct contact with the ore pulp; the positioning hole 405 is used for fixing the telescopic positioning pin 205 on the filter pressing plate 104;
further, the plug 401 protrudes from the sealing shell 406 and extends into the sliding groove 107 by 2 to 3 cm, so as to generate enough resistance to prevent the filter press plate 104 from rotating; the foremost end of the bolt 401 is arc-shaped, so that the bolt 401 can be within a certain error range and can also extend into the sliding groove 107, and cannot be clamped outside the sliding groove 107;
further, the middle section of the latch 401 has a section of the rack 404 with teeth; the rack 404 is engaged with the drive gear 402; the driving gear 402 is connected by the driving shaft 403 and drives it to rotate; a sealing element, such as an O-type sealant, a sealant or a graphite seal, is arranged between the plug 401 and the sealing shell 406, so that solid and liquid in the ore pulp are prevented from entering the inside of the sealing element;
further, the number of the teeth of the driving gear 402 may be 36 teeth or 24 teeth; the proper number of teeth reduces the torque requirement of the motor and makes the movement of the bolt 401 more accurate;
further, the motor is in communication connection with the control system through a wireless communication module and rotates according to instructions of the control system.
In the above embodiments, the description of each embodiment has its own emphasis, and reference may be made to the related description of other embodiments for parts that are not described or recited in any embodiment.
