A filter press filter cloth deslagging curved rod swinging self-cleaning mechanism comprises a filter press array formed by a plurality of unit filter plates, wherein two adjacent filter plates are taken as a unit, the middle interface of the two adjacent filter plates is taken as a center, the two sides of the center are symmetrical, the lower ends of a plurality of bent connecting rods are hinged with each other and hinged with the two sides of each filter plate through side rotating shafts, each bent connecting rod is hinged through two bent rods through a top rotating shaft, and a push-pull structure is formed in the transverse direction. The following is described in terms of a one-cell structure.
The inner side of the bent rod is provided with a support, and a support rod is connected between the two supports on the same side; the two ends of the filter cloth are respectively fixed on the feeders between the adjacent opposite filter plates and respectively extend downwards to the bottom ends of the filter plates, the middle sections of the filter cloth are upwards flush and penetrate through the outer sides of two adjacent support rods on the inner sides of the bent connecting rods, when the filter plates relatively move to a limited tension, the filter cloth sections from the fixing positions of the feeders to the turning positions of the support rods and between the turning positions of the two support rods are flat and straight, and the filter cloth can be pulled by the two support rods to be clear, namely the filter cloth sections from the fixing positions to the turning positions and between the two turning positions can be pulled to be flat and straight; the middle of the top surface of the filter cloth is fixedly provided with a filter cloth rapping rod in the transverse direction of the filter cloth, the length of the rapping rod is consistent with the width of the filter cloth, the filter cloth can be tensioned under the action of gravity, and the filter cloth forms an inverted U-shaped groove structure as a whole. For the whole filter pressing array to be pushed and pulled flexibly, the side rotating shaft and the top rotating shaft can be provided with built-in bearings, the bent connecting rod, the supporting rod and the rapping rod are made of metal materials such as stainless steel, the weight of the rapping rod is moderate, the rapping rod is set according to actual requirements, hollow materials or tubular structures can be adopted in the rapping rod, and the cross section can be rectangular, square or oval. The fixing mode can penetrate into cloth bags with proper size which are preset at two sides of the top end of an inverted U-shaped groove formed by filter cloth, or other modes can be used for fixing a rapping rod on the filter cloth, when the filter plate relatively moves to a limited opening degree, the maximum opening angle is generally referred, the limited opening angle of a bent connecting rod is limited by a positioning pin at the side surface of the filter plate or is determined by the overall operation process of an external machine, when the bent connecting rod reaches the maximum opening angle, the rapping rod drops under the action of gravity, the filter cloth is pulled clearly, so that a filter cake or a filter residue accumulated in a filter chamber in the filter pressing process drops downwards along with the filter cloth pulled out of the filter chamber, thereby achieving the purpose of separating the filter cake or the filter residue from the filter cloth, if the filter plate is pulled to have a certain speed, the rapping rod has upward punching continuity to reach a certain height and drops downwards under the action of the gravity of the rapping rod, and the filter cake or the filter residue repeatedly returns back and forth for several times, the remaining fine filter residue adhering to the filter cloth can be shaken off, which is suitable for filter residues with a not too good viscosity or in the form of particles.
Furthermore, the filter cloth vibrating rod is provided with a top rod hinged with the two opposite bent connecting rod top rotating shafts, a guide rod which faces downwards vertically is arranged in the middle of the top rod, a hanging hammer is arranged at the lower end of the guide rod, when the adjacent filter plates are pulled open suddenly, the filter cloth vibrating rod has inertia which moves upwards, the hanging hammer and the filter cloth vibrating rod can be enabled to impact each other, and when the filter plates move relatively to a limited opening degree, the hanging hammer and the vibrating rod can be in contact with each other. The ejector rods are the top ends of bent connecting rods connected to the opposite side surfaces of the filter plates and connected to two opposite ejector rotating shafts, when two adjacent filter plates are pulled open, the vibrating rod upwards strikes the hanging hammer under the action of the continuity to drive the filter cloth to strongly vibrate, and filter cakes with stronger viscosity such as mud cakes can be vibrated down.
Furthermore, the guide rod penetrates through an opening formed in the ejector rod and is connected with the ejector rod through a bolt, and the bolt can fix the guide rod and adjust the downward extending length of the guide rod. The guide rod is fixed on the ejector rod, the downward extending length of the guide rod can be adjusted, and the guide rod is more suitable for eliminating errors caused by production, design, installation, sites and the like in the actual production process.
Furthermore, more than two sets of the guide rods and the hanging hammers are arranged and evenly distributed on the ejector rods, and the guide rods and the hanging hammers are symmetrically arranged by taking the central plane of the vertical direction of the filter plate, which is vertical to the front surface of the filter plate, as the center, and a plurality of sets of the guide rods and the hanging hammers can be arranged on one ejector rod, generally within three sets, so as to evenly distribute impact force of mutual impact.
Furthermore, the support is fixed at the lower end of the reed on the inner side of the bent rod, and the upper end of the reed is fixed on the inner side of the bent rod, so that the support can rotate under the action of external force. The support is arranged on the spring piece, the spring piece can rotate forward or backward by a small angle, and firstly, the force acting on the filter cloth in the collision process of the hanging hammer and the rapping rod can be buffered, the filter cloth is protected, and in addition, the filter cloth is easier to vibrate.
Furthermore, the curved bar can be composed of two parts, the straight bar is hinged with the arc-shaped bar through a curved bar rotating shaft, and an adjustable position stop block or a limit screw for preventing the arc-shaped bar from excessively rotating towards the inner side is further arranged on the inner sides of the straight bar and the arc-shaped bar. The bent rod is composed of a straight rod and an arc-shaped rod, so that materials can be saved under the condition that the size of the total material is limited, the height of the ejector rod or the opening angle of the bent connecting rod is improved, and errors caused by design can be eliminated.
And a bent rod rotation limiting pin is arranged on the side surface of the plate frame of the filter plate to limit the maximum opening angle of the bent connecting rod. The limiting pin is arranged at a proper position at the lower end of the bent connecting rod, and the required size is determined according to production experiment measurement and calculation.
Furthermore, the hanging hammer is arranged into a rod shape, the direction of the hanging hammer is consistent with that of the filter cloth rapping rod, and the length of the hanging hammer is corresponding to that of the filter cloth rapping rod. The hanging hammer is in a long strip rod shape, so that the force of the rapping rod is more uniform when the rapping rod is beaten.
Furthermore, the lower end of the hanging hammer is embedded with a permanent magnet with the polarity along the vertical direction, the corresponding position of the rapping rod is also embedded with a permanent magnet with the opposite polarity, and the contact surfaces of the permanent magnets have the same polarity and repel each other. When the two like magnetic poles are close to each other, repulsive force is generated, when the repulsive force is large enough, impact and noise caused by collision of the hanging hammer and the rapping rod can be eliminated, and meanwhile, the frequency of shaking the filter cloth up and down along with the rapping rod can be increased (which is equivalent to the same as that of arranging a spring). In the manufacturing process, the permanent magnet can be embedded, so that a certain concave distance is reserved on the permanent magnet relative to the lower end surface of the hanging hammer or the upper end surface of the rapping rod, and the permanent magnet is prevented from being directly impacted and damaged.
Furthermore, an electromagnet with the polarity along the vertical direction is embedded at the lower end of the hanging hammer, a permanent magnet is embedded at the corresponding position of the rapping rod, and current in the direction changing is conducted in a coil of the electromagnet under the control of an external control circuit, so that the rapping rod can vibrate or strike the hanging hammer. Along with the change of the polarity of the electromagnet, the hanging hammer and the rapping rod are attracted and repelled frequently, so that the hanging hammer and the rapping rod can be knocked in a short distance range, the filter cloth can vibrate strongly, the knocking distance range is determined by the elasticity of the filter cloth, the elasticity of the spring leaf below the support and the magnitude of the current of the coil in the electromagnet in the hanging hammer, and the vibration frequency is determined by the frequency of the change of the magnetic pole of the electromagnet. In the case of a filter cake with a high viscosity, this is advantageous in that it can be detached and the filter cloth itself can be cleaned by continuous vibration.
In another mode, the hammer is connected with a U-shaped curved rod, and three sections of a first section of the curved rod, a second section of the curved rod and a third section of the curved rod are connected in a plane in an end-to-end smooth round angle mode to form a U shape; one section of the bent rod is connected with the hanging hammer, is vertical to the guide rod, is parallel to the support rod and extends outwards beyond the edge of the filter cloth; the second section of the curved bar is vertical to the first section of the curved bar; the three sections of the bent rod are vertical to the two sections of the bent rod to form a U-shaped structure together. The two sections of the U-shaped curved bars should exceed the edges of the filter cloth so as not to affect the flatness of the filter cloth. In addition, the length of the two sections of the bent rod is moderate, so that the three sections of the bent rod cannot touch the filter plate.
Or a U-shaped curved rod extends out of the hanging hammer, the first curved rod section, the second curved rod section and the third curved rod section are centered on a vertical central plane of the filter plate in the vertical direction, and the symmetrical U-shapes on the two sides are closed into a ring. The two ends of the guide rod are connected with the first section of the curved rod, the second section of the curved rod, the third section of the curved rod, the second section of the curved rod and the first section of the curved rod in an end-to-end connection mode to form a square closed shape, and therefore balance of the two sides of the guide rod is facilitated.
Furthermore, the two sections of the curved bar of the U-shaped curved bar are arc-shaped sections. The shape of the U-shaped curved bar can be various and is determined according to requirements, and particularly the shape of three sections of the curved bar can be designed into a flat fishbone shape, so that the contact surface is larger when the U-shaped curved bar is contacted with the filter cloth. Therefore, the force bearing area for beating the filter cloth is larger, and the filter cloth is more beneficial to cleaning.
Furthermore, the U-shaped curved bar can rotate around the axial lead of one section of the curved bar relative to the hanging hammer, a driving motor connected with one section of the curved bar is arranged in the hanging hammer, after the driving motor is started, one section of the curved bar can swing back and forth around the axial lead of the section of the curved bar, the two sections of the curved bar and the three sections of the curved bar are driven by the one section of the curved bar to knock the filter cloth on the two sides, and the swing angle of the two sections of the curved bar is within the range limited by the inner side of the curved bar. The driving motor can be a cam motor or a motor swinging around a shaft, and can swing within a range limited by an inverted U-shaped groove structure which is slightly larger than the filter cloth, so that the filter cloth on two side walls of the U-shaped groove is hit, and the hitting to the inner side of the bent connecting rod is avoided.

Only one row of holes are arranged, so that the pressure of cleaning liquid or water is more concentrated, and the scanning and washing effects are better. The working area is here the part of the filter cloth that will enclose the filter cake when the filter cake is pressed, i.e. the part of the filter cloth that is on both sides in the filter chamber, and is referred to in the following description as working area.
In another mode, the cleaning cloth is not washed by a U-shaped curved rod, the supporting rod is of a tubular structure with two closed ends, micropores are distributed on the inner side (one side of the filter cloth on the opposite surface), when cleaning liquid is input by an external hose, the cleaning liquid can be sprayed to the working area of the filter cloth on the opposite surface from the micropores, and the micropores designed on the supporting rods of the tubular structures on the two sides can be simultaneously penetrated and sprayed with the cleaning liquid or sprayed with the cleaning liquid in a time-sharing manner. The whole working area of the filter cloth can be washed under high pressure.
In another mode, the guide rod and the hanging hammer are separated, a guide rod raised head is arranged at the lower end of the guide rod, a through hole is formed in the center of the hanging hammer, a limiting groove is further formed in the position, connected with the through hole, of the guide rod, the upper end of the guide rod can penetrate through the through hole of the hanging hammer, the raised head at the lower end of the guide rod is matched with the limiting groove to prevent the hanging hammer from falling off the guide rod, and the hanging hammer can slide in the middle of the guide rod. The shape of the through hole corresponds to the cross section of the guide rod, the raised head can be in a square shape, a spherical shape or a conical shape, the shape of the limiting groove is changed correspondingly according to the shape of the raised head, the guide rod can also be in a cuboid shape, a cylinder shape and the like, the guide rod can be made of stainless steel, the hanging hammer can be made of polymer materials which are impact-resistant, difficult to deform and plastic, such as potassium-oxygen-potassium base and the like, the materials do not produce magnetic shielding and can be insulated, the hanging hammer is a good material, and the hanging hammer can also be made of metal materials or other solid materials.
Furthermore, the guide rod and the hanging hammer are separated bodies, a mounting groove is formed in the lower end of the hanging hammer, an electromagnet is arranged in the mounting groove, a permanent magnet is arranged at the corresponding position of the rapping rod, the electromagnet is electrified under the control of an external control circuit to change the direction of current, the generated electromagnetic field can interact with the permanent magnet in the rapping rod, the hanging hammer can slide up and down along the guide rod, and the rapping rod is knocked at the same time. The rapping rod drives the filter cloth to shake, and the filter cake and large filter residues in the filter cloth can shake off quickly by knocking.
Furthermore, the electromagnet is electrified with current in a variable direction under the control of an external control circuit, the size of the electromagnet is adjusted, the hanging hammer is driven to slide on the guide rod, and the force for striking the rapping rod can be controlled.
Furthermore, the electromagnet is electrified with the frequency of the current in the changing direction under the control of an external control circuit, so that the hanging hammer can slide on the guide rod, and the frequency of striking the rapping rod can be controlled. The vibrating rod can drive the filter cloth to vibrate, fine slag on the filter cloth can drop quickly through vibration, and the cleanliness of the filter cloth is further improved.
In another mode, the guide rod and the hanging hammer are connected into a whole, a motor groove is formed in the lower end of the hanging hammer, a vibration motor is arranged in the motor groove, a motor shaft protrudes downwards into a motor shaft adapting groove formed in the corresponding position of the rapping rod, and the vibration motor is electrified to drive the rapping rod to vibrate under the control of an external circuit. The rapping rod drives the filter cloth to vibrate, so that filter residues on the filter cloth can fall off quickly.
Specifically, the vibration motor is a cam motor. The cam is driven by a common motor, and the cam drives the rapping rod to vibrate.
Further, the vibration motor is a high-frequency vibration motor. The high-frequency vibration motor drives the eccentric blocks at two ends to generate centrifugal distance and centrifugal force by utilizing a high-speed rotating motor, and generates vibration to obtain exciting force. Therefore, the rapping rod can generate high-frequency resonance, so that filter residues can fall off more quickly. The frequency is close to 150 HZ/S.
Further, the vibration motor is an ultrasonic vibration motor. The ultrasonic vibration motor can convert electric energy into ultrasonic vibration of the elastic body, and the working frequency is more than 20kHZ, so that the vibrating rod can drive the filter cloth to vibrate rapidly at the frequency, and the aim of high-efficiency cleaning is fulfilled.
In another mode, the feeder is located in a middle feeding mode (the other feeding modes are similar to the feeding modes from the vertical plane direction of the filter plates), the outer periphery of the filter cloth feeder is connected, a feeding hole in the feeder corresponds to and is fixed with a corresponding feeding hole in a diaphragm of the filter plate, when the two filter plates are folded, the two feeders on the two filter plates are mutually butted, a feeding groove in the feeder is located on one surface, far away from the diaphragm, of the filter cloth, and materials can enter a filter chamber formed by the filter cloth and the frame of the filter plate through the feeding groove in the feeder. The filter cloth is characterized in that one side (close to the filter chamber) of the filter cloth on the periphery of the feeder, which is far away from the diaphragm, is provided with annular cloth, the center of the annular cloth is the same as the center of the feeder, the inner welt and the outer welt of the annular cloth are both tightly connected with the filter cloth (the connection can be in a sewing mode or a thermoplastic welding gun mode and the like), the rest part in the middle of the ring is a non-joint area, two annular cloth openings are arranged along the radial horizontal direction of the annular cloth, the size of the openings is suitable for the size of a pull ring seat arranged on a lantern ring, and the position of the pull ring seat is relatively stable. The lantern ring is arranged in the non-laminating area of annular cloth, and two openings that lie in annular cloth on the lantern ring are respectively just to the pull ring seat, and the both ends of the pull ring that is equipped with articulate on the hole site of pull ring seat, and the middle part of pull ring still is equipped with the trepanning of acting as go-between, and the trepanning of acting as go-between of the opposite face of adjacent filter plate links to each other with the stay cord, and when the filter plate opened gradually, the stay cord was straightened and is driven the lantern ring and outwards remove along annular cloth to can make the filter cloth from being pulled to outside the filter chamber in the filter chamber. The above design is made in a medium feed mode (feeder in the middle of the filter plate) because the filter cloth is fixed around the feeder, which is usually fixed on a rigid core plate, and the feeder itself cannot be pushed or pulled, and only the filter cloth around the feeder can be pulled.
Further, the annular cloth and the filter cloth are made of the same material. In order to prevent the filter cloth from being shielded to influence the filtration and make the edge of the annular cloth better fit with the filter cloth, the same material is a good choice.
More than two uniformly distributed annular cloth openings can be arranged along a plurality of radial directions of the annular cloth. The annular cloth openings may be established in other directions than the horizontal direction.
Further, the inner diameter of the lantern ring is consistent with the outer diameter of the inner welt of the annular cloth. When the filter cloth is attached to the diaphragm, the lantern ring is basically fixed to the periphery of the inner attached edge of the annular cloth and is easy to reset, the filter cloth can be slowly tiled in the filter chamber due to the fact that materials enter from the feeding hole in the feeder and are also the filter pressing objects to the working surface of the filter cloth under the condition that impact is continuously increased, the filter cloth is leveled, the annular cloth is driven to be leveled, and then the lantern ring is reset.
Further, the material of the lantern ring, the pull ring and the pull ring seat is stainless steel. Because the filtrate may contain corrosive liquid, the stainless steel used has corrosion resistance and is strong and durable.
Further, the shape of the lantern ring is matched with that of the annular cloth, and both the lantern ring and the annular cloth are circular rings. The shape of the lantern ring and the shape of the annular cloth can also be regular polygon rings. The section of the lantern ring is circular.
Further, the cross-sectional shape of the collar is elliptical. Because it contacts with the filter cloth and moves in the non-sticking area of the ring cloth, the lantern ring can not have sharp corner edge to prevent the filter cloth from being lacerated or the local stress is too large, and the corner is required to be smooth, so the cross section can adopt the smooth shape of ellipse or circle, etc.
Further, the pull ring is in a semi-circular arc shape, and the diameter of the pull ring is larger than the radial size of the lantern ring. Because the two annular cloth openings are arranged in the radial horizontal direction, and the pull ring seat is also arranged in the two openings, the pull ring is in a natural falling state in a natural state (namely, in a non-working state, when the pull ring is not pulled by the pull rope), and the feeding is not influenced.
Further, the pull rope is a temperature-resistant and corrosion-resistant rope or a stainless steel wire. The draw string requires a material that is temperature and corrosion resistant because the filter cake needs to be heated in the filter chamber and the filtrate may contain corrosive substances.
Further, the radial width of the ring shape of the non-fitting area of the ring-shaped cloth is larger than the depth of the filter chamber. Because the pull ring is consistent with the outer diameter of the inner flange of the annular cloth before being pulled, the pull ring is contacted with the outer flange of the cloth ring when being pulled to the maximum extent, and the filter cloth moves towards the middle of the lantern ring. Thus, to pull the filter cloth out of the filter chamber, i.e. to pull the collar out of the filter chamber, the collar should be moved outwardly a distance greater than the depth of the filter chamber, thus requiring the radial width of the annulus of the non-attachment zone of the annular cloth to be greater than the depth of the filter chamber.
Generally, the bottom end of the filter cloth is fixed by a clamping groove arranged at the bottom end of the filter plate frame and a clamping strip matched with the clamping groove. The upper end and the lower end of the filter cloth can pass through the clamping grooves which are preset at the upper end and the lower end of the filter plate frame, and then are clamped and pressed into the clamping grooves for fixation through the clamping strips which are matched with each other. In this case, the filter cloth does not have to pass around the support bar.
Furthermore, the frame bottom of filter plate is equipped with two bull sticks, including bottom owner bull stick, bottom time bull stick, and the filter cloth is walked around and is passed from the bottom owner bull stick surface and from the clearance between bottom owner bull stick and the bottom time bull stick, and it is downward to be walked around bottom time bull stick surface again, and its tip is fixed on the filter cloth weight pole rather than the width unanimity. Therefore, the filter cloth at the bottom end can be pulled clear from the feeder, and filter residues are further separated from the filter cloth.
In another mode, one side, far away from the diaphragm, of the filter cloth on the periphery of the feeder is provided with annular cloth, the center of the annular cloth is the same as that of the feeder, the inner welt and the outer welt of the annular cloth are both tightly connected with the filter cloth, the remaining part in the middle of the ring is a non-attaching area, the magnetic lantern ring is arranged in the non-attaching area of the annular cloth, the magnetic polarity direction of the magnetic lantern ring is perpendicular to the direction of the filter plate, and the corresponding position of the diaphragm is embedded with corresponding annular electromagnets in shape, size and position. Under the condition, the filter cake or filter residue in the filter cloth can be pushed out of the filter chamber under the pushing of electromagnetic force without a pull ring and a pull rope, so that the aim of separating the filter cake from the filter cloth is fulfilled.
The direction of the coil current in the electromagnet is controlled by an external control circuit, so that when the polarity of the contact surface of the annular electromagnet and the magnetic lantern ring is the same, the lantern ring can be forced to be away from the diaphragm and the filter cloth is driven to protrude out of the filter chamber.
Furthermore, the direction of the coil current in the electromagnet is periodically changed under the control of an external control circuit, and the polarity of the annular electromagnet is changed along with the change, so that the filter cloth can shake. Further shaking off the filter residue to clean the filter cloth.
