Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a papermaking sludge dehydration cake-forming device. Background Art

[0002] The main pollutants in wastewater from waste paper making are the organic matter content and suspended solids in the wastewater. Plate and frame filter press, as a highly efficient dehydration device, is widely used in the dehydration of papermaking sludge. Plate and frame filter press is a commonly used solid-liquid separation equipment. It was used in chemical production in the early 18th century and is still widely used in environmental protection, chemical, pharmaceutical, metallurgy, dye, food, brewing, ceramics and sewage treatment industries.

[0003] During the sludge dehydration process, the plate and frame filter press press presses the inside of the equipment to filter out the water in the sludge through the filter plates. After the equipment stops pressurizing, the sludge remaining inside the filter plates cannot be filtered due to the loss of pressure, resulting in a large amount of water in the mud cake. When the mud cake is separated from the device, the mud cake is easy to stick to the device and is difficult to fall off, which is not conducive to the efficient dehydration of the sludge. The mud cake with high water content is not conducive to storage and transportation, which increases the transportation cost of the enterprise.

[0004] When the filter plate is filtering sludge, its surface filtering capacity will continue to decrease due to the adhesion of sludge. When impurities in the sludge block the filter plate, the filter plate will filter the sludge slowly. The existing filter press uses the water's own weight to make water flow out from the bottom of the filter plate, and the dehydration speed is slow.

[0005] Therefore, a papermaking sludge dehydration cake forming device is proposed. Summary of the invention

The screw rod is rotatably connected to the inside of the second plate frame, a gear rod is fixedly connected to the inside of the second plate frame, the cross plate is slidably connected between the screw rod and the gear rod, the inclined plate is symmetrically slidably connected to both sides of the cross plate, and a second spring is fixedly connected between the inclined plate and the cross plate.

[0011] Preferably, a frequency-vibration mechanism is provided below the transverse plate, and the frequency-vibration mechanism includes a gear shaft, a camshaft and a rubber plate, the gear shaft and the camshaft are rotatably connected to the two ends of the lower surface of the transverse plate, a second transmission belt is transmission-connected between the camshaft and the gear shaft, the gear shaft and the gear rod are meshed, a bracket is fixedly connected to the lower surface of the transverse plate, a rubber plate is slidably connected to the bottom of the bracket, and a third spring is fixedly connected between the bracket and the rubber plate.

[0012] Preferably, the inclined plate tilts downward from the side close to the screw rod to the side close to the filter cloth, the side wall of the inclined plate fits the inner wall of the filter cloth, and a motor is arranged inside the second plate frame, and the output end of the motor controls the reciprocating rotation of the screw rod.

[0013] Preferably, a camshaft is provided with a protrusion, a side edge of the protrusion is an inclined surface, and the rubber plate is in contact with a smooth surface of the camshaft.

[0014] Preferably, a notch matching the shape of the pressing plate is provided on the top of the first plate frame, and a side of the pressing plate close to the first plate frame is arranged as an inclined surface.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the second plate frame is separated from the first plate frame, the pressing plate no longer presses the sliding plate, so that the sliding plate can move upward after separation, and the electric heating copper rod rotates through the meshing of the tooth plate and the gear, thereby ensuring that the outer wall of the electric heating copper rod is separated from the bonding state of the mud cake inside the first plate frame due to its own rotation, reducing the problem that the mud cake cannot be separated cleanly due to bonding with the inner cavity of the first plate frame when it is separated from the first plate frame. By setting the electric heating copper rod inside the first plate frame, the sludge inside the first plate frame can be evaporated under the action of baking, and the water content in the mud cake is reduced, making the mud cake easy to transport and store. When the sliding plate slides at the inner corner of the folding groove, the sliding plate as a whole will tilt, and the electric heating copper rod rotates toward the outside of the sliding plate, so that the mud cake inside the sliding plate is separated from the inside of the sliding plate by the rotation of the electric heating copper rod, and slides down on the outer wall of the electric heating copper rod under the influence of its own weight, thereby improving the efficiency of separating the mud cake from the sliding plate, while reducing the residue of mud cake in the inner cavity of the sliding plate, and improving the working efficiency of sludge dehydration;

[0017] 2. Through the reciprocating sliding of the cross plate inside the second plate frame, the filtered water inside the second plate frame can be quickly discharged through the sewer pipe under the pushing action of the cross plate and the inclined plate. When the inclined plate moves inside the second plate frame, the negative pressure formed in the inner cavity of the second plate frame can make the sludge stored in the first plate frame be fully extracted under the action of negative pressure, thereby improving the equipment's efficiency in extracting water from the sludge. The negative pressure generated by the movement of the inclined plate will also cause the filter cloth to deform due to the pressure difference, so that the filter cloth is pre-separated from the surface of the sludge that is not completely dried inside the first plate frame, reducing the bonding area between the filter cloth and the sludge, and improving the separation efficiency of the filter cloth and the mud cake after dehydration. By beating the filter cloth with the rubber plate, it can be prevented that the impurities in the sludge are clogged by long-term adhesion, thereby ensuring efficient filtration of the filter cloth during sludge dehydration.

The gear shaft 631 and the cam shaft 632 are rotatably connected to the two ends of the lower surface of the horizontal plate 623, and a second transmission belt 633 is transmission-connected between the cam shaft 632 and the gear shaft 631.

[0042] The inclined plate 624 tilts downward from the side close to the screw rod 621 to the side close to the filter cloth 612, and the side wall of the inclined plate 624 fits the inner wall of the filter cloth 612. A motor is arranged inside the second plate frame 611, and the output end of the motor controls the screw rod 621 to rotate back and forth.

[0043] A camshaft 632 is provided with a protrusion, the side of which is an inclined surface, and the rubber sheet 635 fits with the smooth surface of the camshaft 632 .

[0044] A notch matching the shape of the pressing plate 613 is formed on the top of the first plate frame 51 , and a side of the pressing plate 613 close to the first plate frame 51 is configured as an inclined surface.

[0045] The above implementation works as follows:

[0046] The initialization steps are as follows:

[0047] The sludge storage component 5 and the clean water storage component 6 are not fitted together, the slide plate 54 is not squeezed downward by the pressure plate 613, and the first spring 55 is in an unstretched state. The staff controls the plate and frame filter press body 1 to extend the hydraulic press 2 and drive the feed pipe 3 to squeeze the sludge storage component 5 and the clean water storage component 6, so that the sludge storage component 5 and the clean water storage component 6 are fitted together, and then the sewage flows into the first plate frame 51 through the feed pipe 3.

[0048] The working steps are as follows:

[0049] The sludge cake is dried and quickly separated by the sludge storage component 5:

[0050] When the feeding tube 3 pushes the second plate frame 611 to move toward the first plate frame 51, the pressing plate 613 will squeeze the slide plate 54 on the top of the first plate frame 51, so that the slide plate 54 slides toward the inside of the first plate frame 51. During the movement of the slide plate 54, the first spring 55 is stretched and elastically extended. As the slide plate 54 slides inside the folding groove 53, the slide plate 54 is limited by the folding groove 53 and flipped, and the electric heating copper rod 510 rotatably connected to the slide plate 54 is driven to rotate to the inside of the first plate frame 51.

[0051] When the second plate frame 611 and the first plate frame 51 are tightly fitted, the sludge enters the first plate frame 51, and the water in the sludge is filtered into the second plate frame 611 through the filter cloth 612 by the water pressure. After all the sludge is injected, the remaining sludge in the first plate frame 51 will be dried under the high temperature of the electric heating copper rod 510, thereby forming a dry mud cake with low water content.

[0052] When the sludge dehydration is completed, the staff operates the auxiliary moving frame 4 to separate the second plate frame 611 from the first plate frame 51. After the pressure plate 613 no longer presses the slide plate 54, the first spring 55 is no longer stretched and shrinks. The contraction of the first spring 55 drives the slide plate 54 to move upward inside the first plate frame 51. During the upward movement of the slide plate 54, the rotating shaft 57 is driven to move upward together. When the rotating shaft 57 moves upward, the gear 58 meshes with the tooth plate 56 and rotates. When the rotating shaft 57 rotates, it drives the electric heating copper rod 510 to rotate together. The electric heating copper rod 510 The first transmission belt 511 drives multiple electric heating copper rods 510 to rotate together. After the electric heating copper rods 510 rotate, the sludge inside the first plate frame 51 is separated from the outer wall of the electric heating copper rods 510 to avoid the problem of the outer wall of the electric heating copper rods 510 sticking to the sludge. When the slide plate 54 slides to the corner inside the folding groove 53, the slide plate 54 will tilt as a whole, so that the electric heating copper rods 510 drive the mud cake inside the first plate frame 51 to rotate toward the outside of the first plate frame 51, and slide out from the surface of the electric heating copper rods 510 to the bottom of the first plate frame 51.

[0053] When the second plate frame 611 is separated from the first plate frame 51, the pressing plate 613 no longer presses the sliding plate 54, so that the sliding plate 54 can move upward after separation, and the electric heating copper rod 510 is rotated by the meshing of the tooth plate 56 and the gear 58, thereby ensuring that the outer wall of the electric heating copper rod 510 is separated from the adhesion state of the mud cake inside the first plate frame 51 due to self-rotation, reducing the problem that the mud cake cannot be separated cleanly due to adhesion to the inner cavity of the first plate frame 51 when it is separated from the inside of the first plate frame 51. By setting the electric heating copper rod 510 inside the first plate frame 51, the inside of the first plate frame 51 can be The moisture of the sludge evaporates under the baking effect, and the moisture content in the mud cake is reduced, making the mud cake easy to transport and store. When the slide plate 54 slides at the inner corner of the folding groove 53, the slide plate 54 will be tilted as a whole, and the electric heating copper rod 510 rotates toward the outside of the slide plate 54, so that the mud cake inside the slide plate 54 is separated from the inside of the slide plate 54 by the rotation of the electric heating copper rod 510, and slides downward on the outer wall of the electric heating copper rod 510 due to its own weight, thereby improving the efficiency of separating the mud cake from the slide plate 54, while reducing the residue of mud cake in the inner cavity of the slide plate 54, and improving the working efficiency of sludge dehydration.

[0054] The screw rod 621 inside the second plate frame 611 is driven by the motor to rotate forward and reversely. When the water in the sludge enters the second plate frame 611 through the filter cloth 612, the rotation of the screw rod 621 will drive the cross plate 623 to slide back and forth inside the second plate frame 611. When the cross plate 623 moves upward, the inclined plate 624 is hindered by the filtered water inside the second plate frame 611, so that the inclined plate 624 slides on the cross plate 623 to the side away from the filter cloth 612, thereby The inclined plate 624 and the filter cloth 612 are no longer in contact with each other. When the inclined plate 624 moves downward from the upper part of the inner cavity of the second plate frame 611, the inclined plate 624 is subjected to the resistance of the water below it, so that the inclined plate 624 and the inner wall of the filter cloth 612 are closely contacted. As the inclined plate 624 moves downward, the water filtered in the inner cavity of the second plate frame 611 is pushed downward by the inclined plate 624 and the horizontal plate 623, and is discharged to the outside of the second plate frame 611 through the downpipe 614;

[0055] When the inclined plate 624 moves downward, the space inside the second plate frame 611 and above the cross plate 623 will generate negative pressure due to the movement of the inclined plate 624. The negative pressure inside the second plate frame 611 causes the moisture in the sludge stored in the first plate frame 51 to be extracted into the interior of the second plate frame 611. At the same time, the filter cloth 612 will shrink toward one side of the second plate frame 611 under the action of the negative pressure in the inner cavity of the second plate frame 611. The deformation generated by the filter cloth 612 can pre-separate the mud cake inside the first plate frame 51 from the outer wall of the filter cloth 612, so that the sludge inside the first plate frame 51 reduces the bonding area with the filter cloth 612 after drying, thereby improving the success rate of separation.

[0056] When the cross plate 623 moves inside the second plate frame 611, the gear shaft 631 meshes with the gear rod 622 and rotates at the same time. The gear shaft 631 rotates and causes the cam shaft 632 to rotate together through the second transmission belt 633. During the rotation of the cam shaft 632, the protrusions on the surface of the rubber plate 635 will cause intermittent pushing. The third spring 636 is in a state of continuous extension and contraction. After being pushed, the rubber plate 635 will reciprocately slap the inner wall of the filter cloth 612, thereby slapping the sludge adhered to the surface of the filter cloth 612, avoiding clogging of the filter cloth 612 by larger particles in the sludge, and enabling the filter cloth 612 to maintain a relatively smooth filtering condition when filtering the sludge, thereby improving the filtering efficiency of the filter cloth 612 on the sludge.

[0057] The reciprocating sliding of the horizontal plate 623 inside the second plate frame 611 allows the filtered water inside the second plate frame 611 to be quickly discharged through the downpipe 614 under the pushing action of the horizontal plate 623 and the inclined plate 624. When the inclined plate 624 moves inside the second plate frame 611, the negative pressure formed in the inner cavity of the second plate frame 611 can fully extract the water in the sludge stored in the first plate frame 51 under the action of the negative pressure, thereby improving the extraction efficiency of the equipment for the water in the sludge. The negative pressure generated by the movement of the inclined plate 624 will cause the filter cloth 612 to deform due to the pressure difference, so that the filter cloth 612 is pre-separated from the surface of the sludge that is not completely dried inside the first plate frame 51, reducing the bonding area between the filter cloth 612 and the sludge, and improving the separation efficiency of the filter cloth 612 and the mud cake after dehydration. The beating of the filter cloth 612 by the rubber plate 635 can prevent the impurities in the sludge from clogging the filter cloth 612 due to long-term adhesion, thereby ensuring efficient filtration of the filter cloth 612 during sludge dehydration.
