Description

Technical Field

[0001] The invention belongs to the technical field of sludge drying and filter pressing, in particular to a sludge drying and filter pressing device. Background Art

[0002] In the sludge treatment process, a sludge drying and filter pressing device is used to preliminarily dehydrate and dry the sludge. The sludge is filtered to remove part of the water in the sludge and discharge it in the form of a mud cake. Then the dense mud cake needs to be crushed to disperse and thin the sludge, and then it is sent to the drying equipment for drying. Since the sludge pressed out by the filter press is in a dense mud cake state, the degree of dispersion and thinning directly through the crushing mechanism is limited, and the efficiency and effect of the crushing operation will also be reduced. The phenomenon of uneven and insufficient dispersion and thinning often occurs, and lumpy sludge will still appear, resulting in the lumpy sludge agglomerating after being dried by the drying mechanism, which is not convenient for subsequent sludge treatment. In addition, the mud cake after the filter press has high viscosity, so it is easy to adhere to the fixed pressure plate at the traditional discharge port in large quantities, which can easily cause blockage.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention provides a lower extrusion plate, a spring 1 and a dispersion circular hole plate, so that the sludge spiral filter press squeezes the sludge toward the discharge port, so that the sludge squeezes and pushes the lower extrusion plate, the upper extrusion plate, the connecting rod, the connecting frame 1, the square bar and the lifting block to move outward and press the filter. At this time, the spring 1 is compressed. When the lifting block moves and squeezes and pushes the protrusion to move upward, it can drive the movable rod and the clamping block 1 to move upward, and release the clamping fixation of the movable rod. At this time, due to the elastic recovery effect of the spring 2, the movable rod, the connecting frame 2 and the sealing arc plate will be driven to move outward, and the sealing of the bottom of the inner cylinder will be released, so that the sludge will lose the restriction of the sealing arc plate, and under the elastic recovery effect of the spring 1, the sludge in the inner cylinder is pushed downward by the reverse pressure of the lower extrusion plate and the upper extrusion plate. Extrusion, and under the action of extrusion force, the sludge passes through the dispersion circular hole plate, and is dispersed and thinned by the circular holes on the dispersion circular hole plate to reduce the density of the sludge. The motor drives the gear to rotate, driving the gear ring and the four-leaf cutter to rotate. Under the shearing effect generated by the rotation of the four-leaf cutter, the loose sludge squeezed out of the dispersion circular hole plate can be further cut to achieve the effect of preliminary crushing, so that the sludge enters the interior of the crushing mechanism in a crushed and loose state. This design can reduce the working intensity of the crushing mechanism and avoid mechanical fatigue. At the same time, it improves the degree of dispersion and thinning of the sludge by the crushing mechanism, making the sludge easier to be crushed and loosened by the crushing mechanism evenly and fully, avoiding the appearance of blocky sludge, thereby avoiding agglomeration after subsequent drying.

[0018] The present invention is provided with an upper extrusion plate, a sleeve rod and a second clamping block. When the sealing arc plate pops out to the outside and opens, the moving rod can be driven to move outward and finally abut against the pressure sensing element to trigger it. Due to the triggering of the pressure sensing element, the electromagnetic push rod can drive the push sleeve rod and the upper extrusion plate to move inward, and finally the clamping groove of the sleeve rod moves to the second clamping block. Due to the elastic recovery effect of the spring five, the second clamping block can be clamped in the clamping groove to fix the sleeve rod, and the tension spring one is stretched. Since the upper extrusion plate is pushed out to one side of the sludge, the sludge block in a dense state can be squeezed and deformed by the upper extrusion plate, thereby breaking the integrity of the sludge block inside the inner cylinder, making it easier for the sludge to detach from the inner cylinder, and avoiding the problem that the sludge in a dense state is not easy to squeeze out. At the same time, the elastic recovery effect of the spring one drives the upper extrusion plate and the lower extrusion plate to push and squeeze the sludge in the inner cylinder, which can prevent the sludge from adhering to the inner cylinder, thereby avoiding the phenomenon of sludge clogging.

[0019] The present invention provides a second card block, an inclined block and an inclined block. After the upper extrusion plate and the lower extrusion plate are reset by the elastic force of the first spring, the inclined block can be squeezed and retracted into the square rod by the fixed shell again. At this time, the spring four is compressed. At the same time, under the elastic force recovery action of the second tension spring and the fifth spring, the piston rod two and the card block two will be driven to move inward, and the card block two will be disengaged from the card slot of the sleeve rod, so that the fixing effect of the sleeve rod and the upper extrusion plate can be released. Due to the elastic force recovery action of the first tension spring, the upper extrusion plate can be driven to reset and retract, so as to facilitate the subsequent continued filtration and further facilitate the subsequent continued use of the upper extrusion plate.

The moving rod 538 One end of the movable rod 538 extends to the outside of the fixed cylinder 537 and is connected to the second connecting frame 5310, the other end of the movable rod 538 is connected to the second spring 539, the other end of the second spring 539 is connected to the inner wall of the fixed cylinder 537, the sealing arc plate 5317 is sleeved with a lower extrusion plate 531, the front and rear sides of one side of the lower extrusion plate 531 are connected to the connecting rod 532, the other end of the connecting rod 532 passes through the inner cylinder 52 and extends to the outside of the fixed shell 51 and is connected to the first connecting frame 534, and the spring 533 located outside the connecting rod 532 is connected between the lower extrusion plate 531 and the inner wall of the inner cylinder 52;

[0038] A dispersion circular hole plate 56 located below the sealing arc plate 5317 is installed inside the fixed shell 51 .

[0039] The above scheme is adopted: the sludge spiral filter press 1 squeezes the sludge toward the discharge port, so that the sludge squeezes and pushes the lower squeezing plate 531, the upper squeezing plate 555, the connecting rod 532, the connecting frame 1 534, the square bar 535 and the lifting block 536 to move outward and filter. At this time, the spring 1 533 is compressed. Due to the elastic recovery effect of the spring 2 539, the moving rod 538, the connecting frame 2 5310 and the sealing arc plate 5317 are driven to move outward, releasing the sealing of the bottom of the inner cylinder 52, so that the sludge will lose the restriction of the sealing arc plate 5317, and under the elastic recovery effect of the spring 1 533, the sludge in the inner cylinder 52 is squeezed downward by the reverse pressure of the lower squeezing plate 531 and the upper squeezing plate 555, and under the action of the squeezing force, the sludge passes through the dispersion circular hole plate 56 and is dispersed and sparse by the circular holes on the dispersion circular hole plate 56, so as to reduce the density of the sludge.

[0040] like Figure 3 , Figures 5 to 9As shown, a fixing frame 5311 located outside the fixing shell 51 is connected to the top of the fixing cylinder 537, and a movable sleeve is provided inside the fixing frame 5311 with a movable plate 5312. Movable rods 5313 are connected to both sides of the bottom of the movable plate 5312. The bottom end of the movable rod 5313 is connected to a clamping block 5314 extending into the sealing arc plate 5317, and the clamping block 5314 can be clamped in the moving rod 538. Springs 3 5315 are connected to both sides of the top of the movable plate 5312, and the top of the spring 3 5315 is connected to the top of the inner cavity of the fixing frame 5311. One side of the connecting frame 1 534 is in contact with the connecting frame 2 5310. A square bar 535 is connected to the top of one side of the connecting frame 1 534, and a lifting block 536 is connected to the top of the square bar 535. The bottom of the movable plate 5312 is connected to a protrusion 5316 located above the square bar 535.

[0041] The above scheme is adopted: when the lifting block 536 moves to the protrusion 5316, the protrusion 5316 and the movable plate 5312 will be squeezed by the lifting block 536 and move upward along the inside of the fixed frame 5311. At the same time, the spring three 5315 is compressed. Due to the rise of the protrusion 5316, the movable rod 5313 and the clamping block 1 5314 can be driven to move upward and the clamping fixation of the movable rod 538 can be released. At this time, the elastic force of the spring two 539 in the compressed state can be released.

[0042] like Figure 3 , Figure 4 , Fig.10 and Fig.11 As shown, it also includes a pushing assembly 55, which is sleeved in the inner cylinder 52 and can be connected to the lower extrusion plate 531. The pushing assembly 55 includes a mounting frame 551, which is connected to the lower extrusion plate 531. One side of the mounting frame 551 is connected to a square rod 556, the other end of the square rod 556 passes through the inner cylinder 52 and extends to the outside of the fixed shell 51 and is connected to the connecting frame 1 534, the other end of the mounting frame 551 is connected to a tension spring 1 554, the other end of the tension spring 1 554 is connected to an upper extrusion plate 555 located above the lower extrusion plate 531, the upper extrusion plate 555 can abut and match with the lower extrusion plate 531, the front and rear sides of one side of the upper extrusion plate 555 are connected to a sleeve rod 552 movably sleeved inside the mounting frame 551, and the outer side of the sleeve rod 552 is fixedly sleeved with a limiting block 553 that can abut against the mounting frame 551.

[0043] By adopting the above scheme, when the sleeve rod 552 and the upper squeezing plate 555 are pushed inward, the upper squeezing plate 555 is pushed toward one side of the sludge, so that the dense sludge block can be squeezed and deformed by the upper squeezing plate 555, thereby breaking the integrity of the sludge block inside the inner cylinder 52 and making it easier for the sludge to detach from the inner cylinder 52.

[0044] like Figure 3 , Figure 4 , Fig.10 and Fig.11 As shown, a T-tube 557 is installed inside the mounting frame 551 and the square rod 556, and piston rods 5512 are movably sleeved on both sides of the T-tube 557. One end of the piston rod 5512 is connected to a tension spring 5513, and the other end of the tension spring 5513 is connected to the inner wall of the T-tube 557. The other end of the piston rod 5512 is connected to a spring 5514 located inside the mounting frame 551, and the other end of the spring 5514 is connected to a clamping block 5515 movably sleeved inside the mounting frame 551, and a clamping groove is provided on the sleeve rod 552.

[0045] With the above solution, when the sleeve rod 552 and the upper extrusion plate 555 move inward, the slot of the sleeve rod 552 moves to the second block 5515. Due to the elastic recovery effect of the spring five 5514, the second block 5515 can be engaged in the slot to fix the sleeve rod 552.

[0046] like Figure 3 , Figure 4 , Fig.10 and Fig.11 As shown, a piston rod 558 is provided in a central movable sleeve inside the T-tube 557, one end of which is connected to an inclined block 559 located inside the square rod 556, and a ramp block 5510 capable of abutting against the inclined block 559 is movably sleeved inside the square rod 556, the top of the ramp block 5510 can abut against the inner wall of the fixed shell 51, a spring 5511 is connected to the inner wall of the ramp block 5510, and the other end of the spring 5511 is connected to the inner wall of the square rod 556.

[0047] Adopting the above scheme: when the lower extrusion plate 531 squeezes the sludge and moves outward, it can drive the mounting frame 551 and the square rod 556 to move together. At this time, the inclined block 5510 will be separated from the fixed shell 51. At the same time, the spring four 5511 in the compressed state will push the inclined block 5510 to move upward and eject from the square rod 556 due to the recovery effect of the spring. Since the inclined block 5510 moves upward, it can push the inclined block 559 and the piston rod one 558 to move to the left, and push the piston rod two 5512 to move toward the sleeve rod 552 through air pressure. At this time, the tension spring two 5513 is stretched, and the spring five 5514 is compressed. Due to the elastic recovery effect of the spring five 5514, pressure can be applied to the block two 5515 and abut against the sleeve rod 552.

[0048] like Figure 8 and Fig.10 As shown, a pressure sensing element 5318 is installed on one side of the interior of the fixed cylinder 537 , and an electromagnetic push rod 57 is installed in the fixed shell 51 , and the output end of the electromagnetic push rod 57 extends to the interior of the inner cylinder 52 .

[0049] The above scheme is adopted: when the sealing arc plate 5317 pops out to open, it can drive the moving rod 538 to move outward, and finally abut against the pressure sensing element 5318 to trigger it. Due to the triggering of the pressure sensing element 5318, the electromagnetic push rod 57 can drive the push sleeve rod 552 and the upper extrusion plate 555 to move inward, thereby having a good pushing effect on the sleeve rod 552 and the upper extrusion plate 555.

[0050] like Fig.12 and Fig.13 As shown, it also includes a shearing assembly 54, which is arranged in the fixed shell 51. The shearing assembly 54 includes a gear ring 541, which is movably installed in the fixed shell 51 and is located below the dispersion circular hole plate 56. A four-leaf cutter 542 is installed inside the gear ring 541.

[0051] By adopting the above scheme, under the shearing action generated by the rotation of the four-leaf cutter 542, the loose sludge squeezed out from the dispersion circular hole plate 56 can be further cut to achieve the effect of preliminary crushing, so that the sludge enters the interior of the crushing mechanism 4 in a crushed and loose state, thereby making the sludge easier to be crushed and loosened by the crushing mechanism 4 evenly and fully.

[0052] like Fig.12 and Fig.13 As shown, a mounting block 543 is installed on the back of the fixed shell 51 , and a gear 544 driven by a motor is movably installed inside the mounting block 543 , and the gear 544 is meshed with the gear ring 541 .

[0053] With the above solution, the motor drives the gear 544 to rotate, thereby driving the gear ring 541 and the four-leaf cutter 542 to rotate, thereby driving the four-leaf cutter 542 to perform rotational shearing.

[0054] The working principle and use process of the present invention:

[0055] The sludge spiral filter press 1 filters the sludge through the discharging mechanism 5, and then discharges the filtered sludge through the discharging mechanism 5, and then falls into the crushing mechanism 4 for crushing treatment, and then the loose sludge is transported to the drying mechanism 3 through the conveying mechanism 2 for drying treatment.

[0056] The sludge screw filter press 1 squeezes the sludge toward the discharge port. As the sludge is squeezed out, it abuts against the lower squeezing plate 531 and the upper squeezing plate 555 and is filtered under the reaction of the force. As the sludge screw filter press 1 continuously squeezes out the sludge, the filtered sludge pushes the lower squeezing plate 531, the upper squeezing plate 555, the connecting rod 532, the connecting frame 534, the square bar 535 and the lifting block 536 to move outward. At this time, the spring 5 33 is compressed, and under the elastic force recovery effect of spring 1 533, the lower squeezing plate 531 and the upper squeezing plate 555 can be pushed in the opposite direction to continuously press the squeezed sludge, so that the subsequent sludge can be continuously filtered. As the amount of sludge inside the fixed shell 51 increases, the upper squeezing plate 555 and the lower squeezing plate 531 will move outward together. When the lifting block 536 moves to the convex block 5316, the convex block 5316 and the movable plate 5312 will be affected by the lifting block 5 36 is squeezed and moves upward along the inside of the fixed frame 5311. At the same time, the spring three 5315 is compressed. Due to the rise of the protrusion 5316, the movable rod 5313 and the block one 5314 can be driven to move upward. At this time, the spring two 539 in a compressed state will drive the movable rod 538, the connecting frame two 5310 and the sealing arc plate 5317 to move outward due to the recovery effect of the elastic force, thereby releasing the sealing of the bottom of the inner cylinder 52. Finally, the connecting frame two 5310 moves to abut against the connecting frame one 534. At this time, the sludge after pressure filtration in the inner cylinder 52 will lose the restriction of the sealing arc plate 5317, and under the elastic recovery effect of the spring one 533, the sludge in the inner cylinder 52 is squeezed downward by the reverse pressure of the lower squeezing plate 531 and the upper squeezing plate 555, and under the action of the squeezing force, the sludge passes through the dispersion circular hole plate 56 and is dispersed and sparse by the circular holes on the dispersion circular hole plate 56, so as to reduce the density of the sludge.

[0057] Due to the operation of the motor, the gear 544 will be driven to rotate, and the meshing will drive the gear ring 541 and the four-leaf cutter 542 to rotate. Under the rotation of the four-leaf cutter 542, the loose sludge squeezed out from the dispersion circular hole plate 56 can be further cut to achieve the effect of preliminary crushing, so that the sludge enters the interior of the crushing mechanism 4 in a crushed and loose state.

[0058] Due to the elastic recovery effect of spring one 533, the connecting frame one 534 will be driven to reset and move. At this time, the connecting frame one 534 will drive the connecting frame two 5310, the sealing arc plate 5317 and the moving rod 538 to reset in the opposite direction. At this time, the spring two 539 is compressed. When the square rod 556 is reset, the lifting block 536 releases the squeezing of the protrusion 5316. At this time, the elastic force of spring three 5315 is restored and pushes the moving plate 5312, the movable rod 5313 and the clamping block one 5314 to reset and continue to be clamped in the moving rod 538 and continue to be fixed, so as to form a cycle later.

[0059] When the lower extrusion plate 531 moves outward by squeezing the sludge, the mounting frame 551 and the square rod 556 can be driven to move together. At this time, the inclined surface block 5510 will be separated from the fixed shell 51. At the same time, the spring four 5511 in the compressed state will push the inclined surface block 5510 to move upward and be ejected from the square rod 556 due to the recovery effect of the spring. Since the inclined surface block 5510 moves upward, the inclined block 559 and the piston rod one 558 can be pushed to move to the left, and the piston rod two 5512 can be pushed toward the sleeve rod 552 by air pressure. At this time, the tension spring two 5513 is stretched, and the spring five 5514 is compressed. Due to the elastic recovery effect of the spring five 5514, the card block two 5515 can be pressed and abutted against the sleeve rod 552. When the sealing arc plate 531 is closed, the sealing arc plate 531 is opened. When the lever 538 pops out to open, it can drive the moving rod 538 to move outward, and finally abut against the pressure sensing element 5318 to trigger it. Due to the triggering of the pressure sensing element 5318, the electromagnetic push rod 57 can drive the pushing sleeve rod 552 and the upper extrusion plate 555 to move inward, and finally the card slot of the sleeve rod 552 moves to the second card block 5515. Due to the elastic recovery effect of the spring five 5514, the second card block 5515 can be connected to the card slot to fix the sleeve rod 552, and the tension spring one 554 is stretched. Since the upper extrusion plate 555 is pushed to one side of the sludge, the sludge block in the dense state can be squeezed and deformed by the upper extrusion plate 555, thereby breaking the integrity of the sludge block inside the inner cylinder 52 and making it easier for the sludge to detach from the inner cylinder 52.

[0060] After the upper extrusion plate 555 and the lower extrusion plate 531 are reset by the elastic force of the spring 1 533, the inclined surface block 5510 can be squeezed and retracted into the square rod 556 by the fixed shell 51 again. At this time, the spring 4 5511 is compressed. At the same time, under the elastic restoring action of the tension spring 2 5513 and the spring 5 5514, the piston rod 2 5512 and the clamping block 2 5515 will be driven to move inward, and the clamping block 2 5515 will be disengaged from the clamping groove of the sleeve rod 552, so that the fixing effect of the sleeve rod 552 and the upper extrusion plate 555 can be released. Due to the elastic restoring action of the tension spring 1 554, the upper extrusion plate 555 can be reset and retracted.
