Description

Technical Field

[0001] The invention relates to the technical field of environmentally friendly sludge treatment, in particular to a mobile filter cake crushing device and a plate-frame filter press thereof. Background Art

[0002] The final disposal of sludge generally adopts the following two measures: one is to use harmless landfill treatment; the other is to use incineration treatment. Landfill disposal is gradually reduced due to the limitation of landfill sites and the possible pollution of groundwater bodies; incineration disposal has the most significant effect on sludge reduction and is also a harmless process, but if the water content is too high, the energy consumption is too high and the cost is high. Whether it is sludge landfill or incineration, sludge reduction treatment is a problem faced by all sewage treatment plants. The first step of sludge reduction is to separate the water in the sludge through dehydration equipment and try to control it at a low level. The lower the water content of the sludge, the lower the cost of its final treatment. The plate and frame filter press, or the high-pressure diaphragm plate and frame press, is the leader of all dehydration equipment. The water content of organic sludge can be controlled below 70%, and the water content of inorganic sludge can be controlled below 50%. In the field of sewage treatment, it is the main sludge dehydration equipment. In order to shorten the time of squeezing and dehydration and reduce the moisture content of the filter cake after squeezing, it is necessary to add appropriate polymer flocculants for conditioning before the sludge enters the press so that the interstitial water in the sludge can be released. Therefore, most of the filter cakes after filtration have a certain viscosity and are not easy to break. Furthermore, although the plate and frame filter press can achieve a lower moisture content of the filter cake after squeezing than other dehydration equipment, and can automatically complete the feeding, squeezing, plate pulling, and unloading, it cannot achieve continuous feeding for squeezing. After the sludge is squeezed, the filter cake needs to be unloaded into the hopper below one plate frame after another, and then sent to the subsequent equipment through a screw conveyor for deep dehydration and drying. The filter cake with high viscosity is not easy to break when it falls into the hopper below. Although grid breaking bars are set in the hopper, they are fixed and easily form an arch effect in the hopper, preventing it from falling to the bottom of the screw conveyor. The filter cake cannot be sent out from the hopper to the drying equipment for deep drying treatment. It is often necessary to arrange operators to patrol beside the equipment. Once the filter cake arch appears, the operator has to break the arch manually, usually with a long stick. Obviously, not only does it need to increase the operating staff and the labor intensity is high, but it also affects the automatic operation of the dehydration and drying process of the plate and frame filter press, and the processing efficiency of the filter press is low.

[0003] Therefore, how to break up large pieces of filter cake to prevent them from forming an arch in the hopper below the plate and frame filter press becomes a technical problem that needs to be solved. Summary of the invention

[0004] The object of the present invention is to provide a mobile filter cake crushing device and a plate and frame filter press thereof, mainly to solve the problem of how to crush large pieces of filter cake in the prior art to prevent them from forming an arch in the hopper below the plate and frame filter press.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a mobile filter cake crushing device, characterized in that: the mobile filter cake crushing device includes a mobile vibration and positioning integrated mechanism, a filter cake crusher, a guide rail, a vibration rod, a homing contactor and a return contactor, and the mobile vibration and positioning integrated mechanism moves along the guide rail with the filter cake crusher under the traction of an electric traction mechanism.

[0006] Furthermore, the mobile vibration positioning integrated mechanism includes a slider, a pair of lifting guide rods arranged on the top surface of the slider, a piston-type lifter and an adjustable height mounting rod. A roller slide group is provided on the top of the slider; a counter-radiation photoelectric switch is provided on the adjustable height mounting rod.

[0007] Further, the piston lifter is installed on the middle inner side of the top surface of the slider;

[0008] A slide group top plate and a pressure plate are arranged at the top of both ends of the slider, and each set of slide group top plate and pressure plate defines a roller slide group on the guide rail; the lower edge of the slide group top plate and the lower edge of the pressure plate are both higher than the top surface of the guide rail;

[0009] A fixing plate is fixed on the top of each end of the slider, and each fixing plate is connected to a pressing plate and a cleaning plate by connecting bolts. The cleaning plate is located on the inner side of the pressing plate, and the lower edge of the cleaning plate contacts the top surface of the guide rail;

[0010] At the corresponding positions of each slider top plate, cleaning plate and pressure plate, holes for mounting roller slide brackets are provided; the slide brackets have two circular slide pins at the front and rear, which are respectively inserted into the holes of the top plate, cleaning plate and pressure plate;

[0011] The bottoms of both ends of the slider are respectively fixed to a pair of inverted T-shaped stabilizers by fixing screws, the vertical plates of the inverted T-shaped stabilizers are inserted into the opening grooves of the guide rails, and the inverted T-shaped stabilizers are connected to the electric traction mechanism.

[0012] Furthermore, the roller slide group includes a rectangular slide group bracket, four slide group pins, a roller, a roller shaft and retaining rings at both ends of the roller; a through hole larger than the diameter of the roller shaft is opened in the axial direction of the roller, and after the roller shaft passes through the through hole of the roller, the retaining ring is fixed on the retaining ring groove of the roller shaft to limit the displacement of the roller shaft axis, and at the same time, the roller can freely roll on the roller shaft;

[0013] The middle part of the roller is a polished smooth axis, and there are retaining ring grooves for fixing retaining rings at symmetrical positions at both ends. The inner spacing of the retaining ring grooves is greater than the length of the roller; the diameter of both ends of the roller is smaller than the diameter of the middle part of the roller; the ends and the middle of the roller where the diameter changes are the variable shaft diameter positions, and the spacing between the two variable shaft diameter positions is smaller than the inner width of the roller pulley bracket. The total length of the roller must be less than the distance between the inner levels of the slider.

[0014] Further, the filter cake breaker includes four L-shaped support frames, two top rods, two blade ribs and a plurality of blades;

[0015] Four L-shaped support frames are arranged symmetrically in pairs on the left and right sides and parallel in the front and back sides, forming two groups of left L-shaped support frames and right L-shaped support frames in the front and back sides, and two ends of a blade rib plate are respectively connected to one end of the left L-shaped support frame and one end of the right L-shaped support frame of the same group, forming a concave shape;

[0016] The other ends of the L-shaped support frames extend outwards respectively, a top rod is provided between the other ends of the two L-shaped support frames on the left side, and a top rod is provided between the other ends of the two L-shaped support frames on the right side;

[0017] A plurality of blades are mounted on the blade rib plate, with the cutting edges of the blades facing upwards.

[0018] Furthermore, the filter cake crusher is sleeved in the lifting guide rods of the movable vibration positioning integrated mechanism on both sides, the two L-shaped support rods on the front and rear sides of the same side are respectively located on the outside of the pair of lifting guide rods on the same side, and the top rods on the left and right sides are located on the inside of the pair of lifting guide rods on the same side;

[0019] The piston rod of the piston jack on the same side corresponds to the jack on the same side.

[0020] A plate-frame filter press with a mobile filter cake crushing device, the plate-frame filter press comprises a plate frame and a liquid collecting flap, characterized in that: the plate-frame filter press also comprises the above-mentioned mobile filter cake crushing device, the filter cake crusher is mounted on the rapping rods on both sides of the plate-frame filter press, and is located between the bottom of the plate frame of the plate-frame filter press and the liquid collecting flap;

[0021] A pair of mobile rapping and positioning integrated mechanisms are symmetrically installed on the guide rails on both sides of the plate and frame filter press. The guide rails are open square tubes. A corresponding rapping rod is arranged on the inner side of each guide rail, and it is ensured that the highest point is lower than the top surface of the rapping rod when the piston jack is reset.

[0022] When the plate and frame filter press is unloading, the motor drives the chain connected to the inverted T-shaped stabilizer to pull the mobile vibration and positioning integrated mechanism to move back and forth on the guide rail;

[0023] A return contactor is provided at one end of the guide rail, and a homing contactor is provided at the other end of the guide rail. The mobile vibration and positioning integrated mechanism moves along the guide rail with the filter cake crusher between the homing contactor and the return contactor under the traction of the electric traction mechanism. The filter cake crusher collides with the vibration rod under the action of the mobile vibration and positioning integrated mechanism.

[0024] Furthermore, the positioning of the mobile vibration and positioning integrated mechanism is controlled by a set of through-beam photoelectric switches installed thereon through the automatic control system of the plate and frame filter press. The transmitter and receiver of a set of through-beam photoelectric switches are respectively installed on the adjustable height mounting rods of the mobile vibration and positioning integrated mechanism on both sides. The installation position of the through-beam photoelectric switch should be higher than the lowest point of the plate frame, and ensure that the emission light beam can be completely blocked when moved near the plate frame, so that the receiver on the other side cannot receive the light signal. The through-beam photoelectric switch is located at the front end of the sliding block during unloading vibration.

[0025] Furthermore, the rectangular slide bracket of the roller slide group can be installed with 1 to 5 standard rollers, the outer edge width of the slide bracket is greater than the distance between the two variable shaft diameter positions in the roller shaft by 1 to 3 mm, the thickness of the slide bracket is less than the roller diameter by 10 to 20 mm, and the slide bracket does not touch the upper surface of the guide rail.

[0026] Two circular slide group pins are fixed in the middle position of the front and rear frames of the slide group bracket, and the diameter of the slide group pins is smaller than the diameter of the holes on the baffle and the pressure plate; the left and right frames of the slide group bracket are symmetrically provided with 1 to 5 open grooves, the bottom of the groove is semicircular, the diameter of the groove is larger than the axial diameter of the roller end by 1 to 2 mm, and smaller than the axial diameter of the middle part of the roller by 3 to 5 mm, and the center of the semicircular bottom of the groove is lower than the middle position of the frame thickness of the slide group bracket; after the roller slide group is assembled, the roller with the roller is placed in the groove of the left and right frames of the slide group bracket; then it is installed as a whole in the slide group top plate and the pressure plate at both ends of the slider, and all the rollers can contact with both the inner top surface of the slider and the guide rail, so that the gravity of the slider is directly transmitted to the guide rail through the rollers, rather than to the rollers and the slide group bracket.

[0027] That is, the roller slide group consists of 1 to 5 rollers placed on the slide group bracket with an open groove (that is, the left and right frames of the slide group bracket are symmetrically opened with 1 to 5 upper open grooves), and then the front and rear slide group pins of the slide group bracket are mounted in the slider, so that the rollers are in contact with the inner upper top surface of the slider and the upper surface of the guide rail respectively, so that the gravity of the slider is directly transmitted to the guide rail through the rollers. According to the size of the plate frame, roller slide groups with different numbers of rollers are used. The larger the size of the plate frame, the heavier the unloaded filter cake, and the more rollers are used, so that the slider can move smoothly on the guide rail. If the plate frame size is less than 600mm, it is recommended to use a roller slide group with 1 roller; if the size is 800-1000mm, use a roller slide group with 2 rollers; if the size is 1250-1500mm, use a roller slide group with 3 rollers; if the size is 1600-2000mm, use a roller slide group with 5 rollers.

[0028] By removing the end pressure plate connecting bolts 213 (i.e. the connecting bolts between the fixed plate 210 and the pressure plate 211), the roller slide group can be freely moved out of the slider on the rail to replace the worn parts.

[0029] Furthermore, the compressed air inlet at the bottom of the piston lifter of the integrated mechanism for moving vibration and positioning on both sides is connected to the air outlet of the same two-position three-way solenoid valve by a pneumatic hose, and the compressed air pushes the piston rod in the piston lifter to rise, thereby lifting the filter cake crusher.

[0030] In view of the above technical features, the present invention has the following advantages:

[0031] 1. A plate-and-frame filter press with a mobile filter cake crushing device of the present invention achieves the purpose of crushing large pieces of filter cake through the combined action of the vibration of the filter cake crusher and the cutting of the blade on the crusher, thereby preventing the large pieces of filter cake from forming an arch in the hopper below the plate-and-frame filter press.

[0032] 2. The mobile filter cake crushing device of the plate and frame filter press with a mobile filter cake crushing device of the present invention is mainly realized by a mechanism integrating movement, positioning and lifting - a mobile vibration and positioning integrated mechanism in coordination with a filter cake crusher.

[0033] 3. The mobile filter cake crushing device of the present invention automatically locates the relative position of the unloading filter plate by sensing the "brightness" and "darkness" generated by whether the light emitted by its transmitter is blocked by the filter plate through the receiver of the opposing photoelectric switch.

[0034] 4. A plate and frame filter press of the present invention is provided with a filter cake crushing device installed between the bottom of the plate frame (i.e. the filter press body) of the plate and frame filter press and the hopper at the bottom. Before the filter cake is discharged into the hopper, it is first crushed into small pieces of filter cake by the filter cake crushing device. After the small pieces of filter cake fall into the hopper below, they slide onto the screw conveyor at the bottom of the hopper, thereby improving the automation level of the plate and frame filter press, that is, improving the sludge dewatering treatment efficiency, reducing labor intensity, reducing operators, and reducing sludge treatment costs.

[0035] 5. The mobile vibration and positioning integrated mechanism has the self-cleaning ability on the guide rail surface, ensuring that the mobile vibration and positioning integrated mechanism can move back and forth smoothly on the guide rail with the filter cake crusher.

[0036] 6. The roller slide group in the mobile vibration and positioning integrated mechanism of the mobile filter cake crushing device of the present invention is not fixed on the slider, and regular maintenance or replacement of the roller slide group can be conveniently achieved by removing the pressure plate.

[0064] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0065] See also Figures 1 to 20 , Specific embodiment 1, this embodiment 1 provides a plate and frame filter press 11 with a mobile filter cake crushing device, wherein the mobile filter cake crushing device includes a mobile vibration and positioning integrated mechanism 2, a filter cake crusher 3, a guide rail 4, a vibration rod 5, a return contactor 6 and a return contactor 7, and the mobile vibration and positioning integrated mechanism 2 moves along the guide rail 4 with the filter cake crusher 3 under the traction of the electric traction mechanism.

[0066] The mobile vibration positioning integrated mechanism 2 includes a slider 21, a pair of lifting guide rods 22 arranged on the top surface of the slider 21, a piston lifter 23 and an adjustable mounting rod 27. A roller slide group 24 is arranged on the top of the slider 21, that is, a roller slide group 24 is arranged between the slider 21 and the corresponding guide rail 4; a beam-type photoelectric switch 26 is arranged on the adjustable mounting rod 27. The slider 21 moves along the guide rail 4. The piston lifter 23 is used to lift the filter cake crusher 3.

[0067] For example, in the present embodiment 1, two guide rails 4 are provided, one end of one of the guide rails 4 is provided with a return contactor 7, and the other end of the guide rail 4 is provided with a homing contactor 6. The mobile vibration positioning integrated mechanism 2 moves along the guide rail 4 with the filter cake crusher 3 between the homing contactor 6 and the return contactor 7 under the traction of the electric traction mechanism, and the filter cake crusher 3 collides with the vibration rod 5 under the action of the mobile vibration positioning integrated mechanism 2.

[0068] Both guide rails 4 are provided with a mobile vibration positioning integrated mechanism 2, one of which (actually a height-adjustable mounting rod) is provided with a light transmitter of a beam-type photoelectric switch 26, and the other is provided with a light receiver. The mounting position of the beam-type photoelectric switch 26 should be higher than the lowest point of the plate frame 11 (i.e., the plate frame 11 of the plate frame 11 filter press), and ensure that the emission light beam can be completely blocked when it is moved to the vicinity of the clamping plate 14 frame 11 of the plate frame 11 filter press, so that the receiver on the other side cannot receive the light signal, and the photoelectric switch feeds the information back to the automatic control system of the plate frame 11 filter press, and the automatic control system controls the mobile vibration positioning integrated mechanism 2 to move or pause with the filter cake crusher 3 on the guide rail 4 through an electric traction mechanism, and when paused (i.e., the receiver on the other side cannot receive the light signal), it is convenient for the filter cake crusher 3 to crush the filter cake falling from the plate frame 11.

[0069] The filter cake crusher 3 collides with the rapping rod 5 under the action of the mobile rapping positioning integrated mechanism 2. A corresponding rapping rod 5 is arranged on the inner side of each guide rail 4, and ensures that the highest point is lower than the top surface of the rapping rod 5 when the piston jack 23 is reset.

[0070] The piston lifter 23 is installed on the inner middle side of the top surface of the slider 21 . Preferably, the piston lifter 23 is installed on the inner middle side of the slider 21 , and the length of the piston rod is equivalent to the height of the filter cake breaker 3 being lifted.

[0071] A set of slide top plates 25 and pressure plates 211 are respectively provided at the top of both ends of the slider 21. Each set of slide top plates 25 and pressure plates 211 defines a roller slide 24 on the guide rail 4. The lower edge of the slide top plate 25 and the lower edge of the pressure plate 211 are both higher than the top surface of the guide rail 4. The position of the slide top plate 25 is determined by the length of the roller slide 24, and its height should be less than the thickness of the slide to ensure that it does not touch the guide rail 4 during movement. There is a certain gap between the lower edge of the pressure plate 211 and the guide rail 4, and it is recommended that it is more than 10 mm. The pressure plate 211 presses the roller slide 24 tightly to maintain it in a specific area. Two holes for inserting the slide legs 242 are opened at the corresponding positions of the slide top plate 25, the pressure plate 211 and the cleaning plate 212, such as Figures 18 to 20 As shown, the hole of the slide group top plate 25 is the first hole 251, the hole of the pressure plate 211 is the second hole 2111, and the hole of the cleaning plate 212 is the third hole 2121. The second hole 2111 and the third hole 2121 can be waist holes.

[0072] The structure of the roller slide group 24 is as follows: Figures 13 to 17As shown, it is composed of a rectangular slide bracket 241 that can accommodate 1 to 5 rollers 243 with rollers 244. The two sides of the slide bracket 241 are symmetrically arranged with upwardly open notches (i.e., grooves 246 opened at the top). Two circular slide pins 242 are fixed at the front and rear ends of the slide bracket 241. The slide pins 242 are respectively inserted into the holes on the slide top plate 25 and the pressure plate 211 (i.e., the first hole 251 of the slide top plate 25 and the second hole 2111 of the pressure plate 211), so that the rollers 243 are in contact with the inner top surface of the slider 21 and the upper surface of the guide rail 4, ensuring that the weight of the slider 21 is directly transferred to the guide rail 4 by the rollers 243, and does not hinder the slider 21 from driving the filter cake crusher 3 to move smoothly on the guide rail 4. The roller slides 24 are not fixed in the slider 21, and they can be freely taken out on the rail by removing the connecting bolts 213 of the pressure plate 211 for maintenance or replacement of worn parts.

[0073] According to the size of the plate frame, roller slide groups 24 with different numbers of rollers are used. The larger the size of the plate frame, the heavier the unloaded filter cake, and the more rollers are used, so that the slider 21 can move smoothly on the track 4. If the plate frame size is less than 600mm, it is recommended to use a roller slide group 24 with 1 roller; if the size is 800-1000mm, use a roller slide group 24 with 2 rollers; if the size is 1250-1500mm, use a roller slide group 24 with 3 rollers; if the size is 1600-2000mm, use a roller slide group 24 with 5 rollers.

[0074] A fixed plate 210 is respectively arranged on the top of both ends of the slider 21, and each fixed plate 210 is connected to a pressure plate 211 and a cleaning plate 212 by a connecting bolt 213. The cleaning plate 212 is located on the inner side of the pressure plate 211, and the cleaning plate 212 is made of wear-resistant rubber. The lower edge of the cleaning plate 212 contacts the top surface of the guide rail 4 (or the lower edge of the cleaning plate 212 is close to the top surface of the guide rail 4), so as to keep the sliding surface of the guide rail 4 clean, that is, the cleaning plate 212 has a self-cleaning ability for the surface of the guide rail 4, so as to ensure that the mobile vibration and positioning integrated mechanism 2 can move smoothly back and forth on the guide rail 4 with the filter cake crusher 3.

[0075] The bottom of both ends of the slider 21 are respectively fixed to a pair of inverted T-shaped stabilizers 28 by fixing screws 29, and the vertical plate of the inverted T-shaped stabilizer 28 is inserted into the open groove of the guide rail 4, and the inverted T-shaped stabilizer 28 is connected to the electric traction mechanism. The thickness of the vertical plate of the inverted T-shaped stabilizer 28 is slightly smaller than the slot width of the guide rail 4, and the height is preferably 30 to 50 mm from the inner bottom surface of the guide rail 4. The lower value is taken when the size of the guide rail 4 is small, and vice versa, the larger value is taken for the large-sized guide rail 4. The horizontal plate width of the inverted T-shaped stabilizer 28 should be greater than the slot width of the guide rail 4 and less than the width of the guide rail 4. Its length is more than 100 mm, so as to be able to stably move the vibration positioning integrated mechanism 2.

[0076] After the mobile vibration positioning integrated mechanism 2 is installed on the guide rail 4, it is necessary to ensure that there is a gap of 2 to 5 mm between the upper surface of the horizontal plate of the inverted T-shaped stabilizer 28 and the bottom of the guide rail 4. The roller slide group 24, the cleaning plate 212 and the inverted T-shaped stabilizer 28 are arranged at both ends of the slider 21. The beam-type photoelectric switch 26 is located at the front end of the slider 21 (for example, the direction of movement of the filter cake crushing to the thrust plate 13 is the front) through the adjustable mounting rod 27. The installation height must be higher than the bottom of the filter plate to ensure that the light emitted by the photoelectric switch 26 is completely blocked by the filter plate.

[0077] The filter cake crusher 3 includes four L-shaped support frames 31, two push rods 32, two blade ribs 33 and a plurality of blades 34; the four L-shaped support frames 31 are symmetrically arranged in pairs on the left and right sides, and are arranged in parallel in front and back to form two groups of left L-shaped support frames 31 and right L-shaped support frames 31 in front and back, and the two ends of a blade rib 33 are respectively connected to one end of the left L-shaped support frame 31 and one end of the right L-shaped support frame 31 of the corresponding same group to form a concave shape, that is, two concave shaped components (i.e., concave components) are arranged in parallel, and the blades 34 with notches 341 are fixed on the blade ribs 33 at equal distances and in parallel, and the blades 34 are arranged vertically to the blade ribs 33, and the overall structure is a "groove" shape.

[0078] The other ends of the L-shaped support frames 31 extend outwards respectively, a push rod 32 is provided between the other ends of the two L-shaped support frames 31 on the left, and a push rod 32 is provided between the other ends of the two L-shaped support frames 31 on the right; a plurality of blades 34 are mounted on the blade rib plate 33, and the blade edges of the blades 34 face upwards;

[0079] The filter cake crusher 3 is set in the lifting guide rod 22 of the movable vibration positioning integrated mechanism on both sides, and the front and rear of the same side (i.e. Fig.12 The two L-shaped support rods (left for the front and right for the rear) are respectively located on the outside of a pair of lifting guide rods 22 on the same side, and the left and right sides (i.e. Fig.11 The top rods 32 (on the left and right sides in the horizontal direction) are located on the inner side of a pair of lifting guide rods 22 on the same side; the top rods 32 cooperate with the lifting guide rods 22, and also have the function of limiting the left and right movement of the filter cake crusher 3. The two L-shaped support rods on the left and right sides cooperate with the corresponding lifting guide rods 22, and also have the function of limiting the front and rear movement of the filter cake crusher 3. The two lifting guide rods 22 are symmetrically arranged on the outside of the middle of the slider 21, and the outer spacing between them is smaller than the inner distance of the two L-shaped support frames 31 on the same side of the filter cake crusher 3 + 10 to 15 mm. The length of the lifting guide rod 22 is the lifting height of the filter cake crusher 3 + the height from the top surface of the slider 21 to the top surface of the rapping rod 5 + 5 to 20 mm margin, so as to ensure that the filter cake crusher 3 can be lifted and dropped freely and smoothly during rapping and crushing without getting stuck, escaping or tipping.

[0080] The piston rod of the piston lifter 23 on the same side corresponds to the push rod 32 on the same side, and the center of the push rod 32 corresponds to the center of the piston rod of the piston lifter 23 on the mobile rapping and positioning integrated mechanism 2 .

[0081] In this embodiment 1, a plate frame 11 filter press with a mobile filter cake crushing device includes a plate frame 11, a plate frame bracket 12, a thrust plate 13, a clamping plate 14, a plate pull trolley track 15, a plate frame pull trolley 16 and a liquid collecting flap 17, a hopper 18, a screw conveyor 19, and a water pressing pipe 110. These components of the filter press body 1 are the same as those of a general (diaphragm) plate frame 11 filter press. The filter cake crusher 3 moves under the filter press plate frame 11, receives and cuts the filter cake dropped from the plate frame 11, and the crushed filter cake enters the hopper 18 and the screw conveyor 19 in turn.

[0082] The filter cake crusher 3 is mounted on the rapping rods 5 on both sides of the plate frame 11 filter press and is located between the bottom of the plate frame 11 and the liquid collecting flap 17 of the plate frame 11 filter press. One rapping rod 5 corresponds to one track and one mobile rapping positioning integrated mechanism 2.

[0083] A pair of mobile rapping and positioning integrated mechanisms 2 are symmetrically mounted on the guide rails 4 on both sides of the plate frame 11 filter press, and a corresponding rapping rod 5 is arranged on the inner side of each guide rail 4, and it is ensured that the highest point is lower than the top surface of the rapping rod 5 when the piston lifter 23 is reset. The installation height of the guide rail 4 is based on the filter cake breaker 3 not touching any part of the mobile rapping and positioning integrated mechanism 2 when the piston rod of the piston lifter 23 in the mobile rapping and positioning integrated mechanism 2 falls back.

[0084] When the plate frame 11 filter press is unloading, the motor drives the mobile vibration and positioning integrated mechanism 2 to move back and forth on the guide rail 4 through the chain towing the inverted T-shaped stabilizer 28 .

[0085] The positioning of the mobile vibration positioning integrated mechanism 2 is controlled by a set of opposite-beam photoelectric switches 26 installed thereon through the automatic control system of the plate frame 11 filter press. The transmitter and receiver of a set of opposite-beam photoelectric switches 26 are respectively installed on the adjustable height mounting rods of the mobile vibration positioning integrated mechanism 2 on both sides. The installation position of the opposite-beam photoelectric switch 26 should be higher than the lowest point of the plate frame 11, and it is ensured that the emission light beam can be completely blocked when it is moved near the plate frame 11, so that the receiver on the other side cannot receive the light signal. That is, the mobile filter cake crushing device automatically locates the relative position of the unloading filter plate by sensing the "bright" and "dark" generated by the receiver of the opposite-beam photoelectric switch 26 whether the light emitted by its transmitter is blocked by the filter plate.

[0086] The compressed air inlet at the bottom of the piston lifter 23 of the mobile vibration positioning integrated mechanism 2 on both sides is connected to the air outlet of the same two-position three-way electromagnetic valve by a pneumatic hose, and the automatic control system (such as PLC, etc.) of the plate frame 11 filter press controls the air intake and exhaust. The piston rod in the piston lifter 23 is pushed up by compressed air to lift the filter cake crusher 3. When the electromagnetic valve is exhausted, the piston rod in the piston lifter 23 falls, and the filter cake crusher 3 also falls with it. The L-shaped support frame 31 on the left and right sides hits the vibration rod 5 on both sides, generating a strong shear force, and the cutting of the blade 34 on the blade can easily break the large filter cake. That is, through the combined action of the vibration of the filter cake crusher 3 and the cutting of the blade 34 on the crusher, the purpose of breaking the large filter cake is achieved, and the large filter cake is prevented from forming a frame arch in the hopper 18 below the plate frame 11 filter press.

[0087] The plate and frame filter press 11 also includes two liquid collecting flaps 17, which are turned up and closed during squeezing and filtration to collect the squeezed filtrate; when the plate frame 11 is unloading, the two liquid collecting flaps 17 are respectively located on both sides of the filter cake crusher 3, and the turning axes of the two liquid collecting flaps 17 are respectively located between the two rapping rods 5 and the filter cake crusher 3; the top surface of the rapping rod 5 is higher than the upper edge of the liquid collecting flap 17 when it is fully turned down, ensuring that the L-shaped support frame 31 of the filter plate crusher and all components of the filter plate crusher will not touch any part of the liquid collecting flap 17 during rapping.

[0088] The structure of the "groove" of the filter cake breaker 3, the depth of the "groove" is the distance from the top surface of the rapping rod 5 to the highest point when the liquid collecting flap 17 is turned down + the depth of the extension into the hopper. The width of the "groove" can receive the filter material unloaded from the filter cake as much as possible, and ensure that the filter cake breaker 3 will not touch any part of the liquid collecting flap 17 during rapping. The height of the filter cake breaker 3 extending into the liquid collecting flap 17 is generally not less than 20cm from the blade 34 to the upper edge of the liquid collecting flap 17 to avoid splashing when the filter cake is unloaded; the length of the L-shaped support frame 31 extending horizontally outward is based on the positioning of the guide rail 4. The distance between the two blade ribs 33 is not less than 2 / 3 of the length of the blade 34, and then a push rod 32 is fixed near the other end of the two L-shaped support frames 31 on the same side. The blade 34 is facing upward, and the distance between the blade and the upper edge of the blade rib 33 is not less than the thickness of the filter cake to ensure that the blade 34 can cut the filter cake. The blade 34 is installed vertically to the blade rib plate 33, and the blades 34 are arranged parallel to each other at equal distances, with a spacing of no more than 20 cm. The length of the blade 34 is no less than the spacing of the discharge filter plates + the thickness of the filter plates + 20 cm, so as to ensure that the large pieces of filter cake that fall from the discharge filter plates can fall on the crushing blade 34.

[0089] The length of the slider 21 is equivalent to the length of the blade 34 in the filter cake breaker 3, and is processed by a folding machine according to the outer dimensions of the guide rail 4, the size of the roller slide group 24, and the thickness of the inverted T-shaped stabilizer 28.

[0090] A pair of guide rails 4 and a pair of rapping rods 5 are symmetrically arranged on both sides of the plate and frame 11 filter press in the longitudinal direction. A return contactor 6 for the mobile rapping and positioning integrated mechanism 2 is set in the direction of the hydraulic system of one of the guide rails 4, and a return contactor 7 is set at the other end. The installation position of the return contactor 7 should ensure that it can be triggered only after the unloading of the last filter plate is completed, ensuring that all the unloading of the plate and frame 11 can be broken; the installation position of the return contactor 6 should ensure that the edge of the filter cake crusher 3 will not block the action of the liquid collecting flap 17, that is, the mobile rapping and positioning integrated mechanism 2 is completely moved out of the edge of the liquid collecting flap 17, and it cannot affect the normal operation of the liquid collecting flap 17.

[0091] A plurality of blades 34 are arranged on the blade rib plate 33 in parallel and at equal distances, and the spacing between the blades 34 is within 200 mm, so as to ensure that the crushed filter cake can fall into the screw conveyor 19 at the bottom of the hopper 18. The height of the blade edge of the blade 34 protruding from the upper edge of the blade rib plate 33 is equivalent to the thickness of the filter cake, and the length of the blade 34 is more than 200 mm greater than the spacing between the two filter plates when unloading at the filter chamber end, so as to ensure that the filter cake can fall on the crusher.

[0092] The inverted T-shaped stabilizing member 28 of the mobile vibration and positioning integrated mechanism 2 is connected to the traction chain of the electric traction mechanism, and the mobile vibration and positioning integrated mechanism 2 is pulled back and forth on the guide rail 4 by the electrically driven traction device (ie, the electric traction mechanism).

[0093] The plate-frame filter press 11 with a mobile filter cake crushing device in the present embodiment 1 realizes the automatic crushing function of the large filter cake by the mobile vibration positioning crusher through the following operation mode.

[0094] The plate-frame filter press 1 is started, the hydraulic system pressurizes and pushes the pressing plate 14 to press all the filter plates, feeds and maintains the pressure into the filter chamber of the plate-frame 11, starts the secondary squeezing water system to feed high-pressure squeezing water into the diaphragm to maintain the pressure (if any), releases the high-pressure squeezing water (if any), the liquid collecting flap 17 turns down, the piston-type jacking device 23 of the mobile vibration positioning integrated mechanism 2 is fed with air to lift the filter cake crusher 3, and the mobile vibration positioning integrated mechanism 2 moves with the filter cake crusher 3 as a whole. When it moves to the opposite light When the receiver of the electric switch 26 cannot receive the emitted light source, it stops moving, the hydraulic system releases pressure, the pressing plate 14 is separated from the plate frame 11, the plate pulling mechanism pulls the plate to unload, the filter cake on the filter chamber falls onto the blade 34 of the filter plate crusher, the two-position three-way solenoid valve is exhausted, the piston rod on the piston lifter 23 falls together with the filter cake crusher 3, the L-shaped support rod hits the rapping rod 5, and the large pieces of filter cake that fall on the blade 34 are broken; the piston lifter 23 is filled with compressed air again, and the filter cake is again The crusher 3 is lifted and the filter cake crusher 3 is moved forward. When the receiver of the opposing photoelectric switch 26 cannot receive the emitted light source, it stops moving, pulls the plate to unload, and the filter cake on the filter chamber of the plate frame 11 falls onto the blade 34 of the filter cake crusher 3. The two-position three-way solenoid valve is exhausted, and the piston rod on the piston lifter 23 falls together with the filter cake crusher 3. The L-shaped support rod hits the rapping rod 5, and the large pieces of filter cake that fall on the blade 34 are broken; the piston lifter 23 enters compressed air again..., and so on according to the previous step until the filter cake of the last plate frame 11 is unloaded, when the mobile rapping positioning integrated mechanism 2 touches the return contactor 7, the mobile rapping positioning integrated mechanism 2 brings the filter cake crusher 3 back along the guide rail 4 and stops moving when the mobile rapping positioning integrated mechanism 2 touches the homing contactor 6, the piston lifter 23 is exhausted, the filter cake crusher 3 falls on the rapping rod 5, and the liquid collecting flap 17 turns up to wait for the next sludge dehydration work. If the filter cake viscosity is high and one vibration is not ideal, multiple vibrations can be set. The number of vibrations and the realization of each step are realized by the control system of the plate and frame filter press 11.

[0095] The mobile filter cake crushing device is mainly realized by a mobile vibration positioning integrated mechanism that integrates movement, positioning, and lifting in one, and a filter cake crusher 3. The plate frame 11 filter press in this embodiment 1 is installed between the bottom of the plate frame 11 (i.e., the filter press body 1) and the lower hopper 18 by adding a filter cake crushing device. Before the filter cake is discharged into the hopper 18, it is first crushed into small pieces of filter cake by the filter cake crushing device. After falling into the hopper 18 below, the small pieces of filter cake slide onto the screw conveyor 19 at the bottom of the hopper 18, thereby improving the automation level of the plate frame 11 filter press, that is, improving the sludge dewatering treatment efficiency, reducing labor intensity, reducing the number of operators, and reducing the sludge treatment cost.
