The applicant applies for a filter press filter cloth slag-removing self-cleaning mechanism to the national patent office at 12-18.2020, with the application numbers: 202011506676X.
Disclosure of Invention
In order to solve the defects of the prior art, a need exists for a filter cloth deslagging mechanism in a filter press, which is applied to the filter press, can quickly separate out a filter cake and enable the filter cloth to be cleaner, saves a large amount of unnecessary machinery or manpower, and has high deslagging speed and high efficiency.
A filter cloth deslagging mechanism for filter press is composed of a filter press array consisting of several filter plates, two adjacent filter plates as a unit, a central interface between two filter plates, and multiple bent connecting rods hinged to each other and to both sides of filter plate via lateral axles. 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 between the fixed position of the feeder (the feeders are arranged at the bottom ends of the filter plates) and the turning positions of the support rods and between the turning positions of the two support rods are flat, the filter cloth can be pulled by the two support rods to be removed, namely, the filter cloth sections between the fixed position and the turning positions and between the two turning positions can be pulled to be flat; 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 pockets with proper size preset at two sides of the top end of an inverted U-shaped groove formed by filter cloth, or can fix a rapping rod on the filter cloth in other modes, when the filter plate relatively moves to a limited opening degree, the limited opening angle of a bent connecting rod is generally limited by a positioning pin at the side surface of the filter plate or is determined by the total running process of external machinery, when the bent connecting rod reaches the maximum opening angle, the rapping rod falls down under the action of gravity, the filter cloth is pulled clear, so that filter cakes or filter residues accumulated in a filter chamber in the filter pressing process fall down along with the filter cloth pulled out of the filter chamber, and the aim of separating the filter cakes or the filter residues from the filter cloth is fulfilled, if the filter plate is pulled out at a certain speed, the rapping rod has upward punching penetrability, reaches a certain height and falls down under the action of the gravity of the rapping rod, this is repeated several times, which causes the remaining fine filter residue adhering to the filter cloth to be shaken off, which is suitable for filter residues with a not too good viscosity or in the form of particles.
Furthermore, the push rod is hinged with the push rotating shaft of the two opposite bent connecting rods, a guide rod which faces downwards vertically is arranged in the middle of the push 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 rapping rod has inertia which moves upwards, the hanging hammer and the filter cloth rapping rod can be enabled to impact against each other, and when the filter plates move relatively to a limited degree of tension, the hanging hammer and the rapping 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.

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 (or eccentric shaft) motor or a motor swinging around a shaft, and can swing within a range limited by an inverted U-shaped groove structure 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.
Furthermore, the U-shaped curved bar is of a hollow pipeline structure, the free ends of the three sections of the curved bar are closed ends, and spray heads are distributed on two sides of the pipe wall.

The micropores arranged on the supporting rod can be replaced by the spray head. 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.

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 vibration 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 vibrating rod drives the filter cloth to vibrate, filter residues on the filter cloth can fall off quickly, in the actual production process, the vibrating motor is a micro motor and is a direct current motor with an eccentric shaft, the eccentric shaft is movably sleeved in a motor shaft adapting groove of the vibrating rod, the vibrating rod is driven to vibrate during working, the vibrating rod drives the filter cloth to shake, and the vibration frequency is within the range of 50-70 HZ.
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.
Alternatively, the vibration motor is replaced by a high-frequency vibration motor (or high-frequency vibrator). The high-frequency vibration motor is characterized in that the frequency of the motor is modulated to high-speed rotation by a frequency modulation power supply, and the high-speed rotation is utilized to drive eccentric blocks at two ends to generate centrifugal distance and centrifugal force to generate vibration to obtain exciting force. The micro high-frequency vibration motor can be installed as the vibration motor, or directly attached and fixed on the rapping rod, so that the rapping rod can generate high-frequency resonance, and filter residues can fall off more quickly. Its frequency is slightly 150 HZ.
Further, the vibration motor is replaced with 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 the above case, the feeder on the filter plate is located at the lower end of the filter plate, and in another mode, the feeder is located at the center of the filter plate in a middle feeding mode (the feeder is located at the center of the vertical filter plate, in some cases, the feeder is not needed, the feeding hole is used as a reference, and the other feeding modes are similar to the feeding mode from the vertical surface direction of the filter plate), the outer periphery of the filter cloth feeder is connected, the feeding hole in the feeder corresponds to and is fixed with the corresponding feeding hole on the diaphragm of the filter plate, when the two filter plates are folded, the two feeders on the feeder are mutually butted, the feeding groove on the feeder is located on the side, far away from the diaphragm, of the filter cloth, and the material can enter the filter chamber formed by the filter cloth and the frame of the filter plate from the feeding groove on the feeder. One side (close to the side of the filter chamber) of the filter cloth at the periphery of the feeder, which is far away from the diaphragm, is provided with annular cloth, the center of the annular cloth is superposed with the center of the feeder, the inner welt of the annular cloth and the outer welt of the annular cloth are tightly connected with the filter cloth (the connection can be in a sewing mode or a thermoplastic welding mode, etc.), 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.
Alternatively, more than two annular cloth openings may be provided in the radial direction of the annular cloth. This reduces the hindering effect of a part of the annular cloth area on the filtering of the filter cloth.
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. The lantern ring is close to with the interior limit of annular cloth, and when the filter cloth was laminated with the diaphragm like this, the lantern ring was fixed in the periphery of annular cloth interior welt basically and is easily resetd, and in the course of the work because the feed inlet from the feeder gets into the material also be filter-pressing object to filter cloth working face, under its constantly increase impact condition, can slowly make the filter cloth tile among the filter chamber, and the filter cloth is evened up and is driven annular cloth and evened up and then make the lantern ring 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.
Furthermore, the pull ring is semicircular, and the diameter of the pull ring is slightly larger than the diameter of the sleeve 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 weight pole of the filter cloth rather than 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.
