Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage treatment, in particular to a multi-stage wastewater treatment device based on paper straw processing. BACKGROUND

[0002] In the paper straw processing production link, equipment cleaning, workshop cleaning and part of the process will produce a certain amount of wastewater. These wastewaters usually contain a large amount of adhesives, dust, paper fibers, mold release agent residues and trace oil stains and other pollutants. Since the paper straw production has a high hygiene standard, the cleaning frequency is high and the water consumption is relatively concentrated, resulting in high suspended solids concentration and high turbidity in the discharged wastewater, and containing difficult-to-degrade colloidal organic matter. Direct discharge not only violates environmental protection regulations, but also easily causes pipeline blockage and ecological system imbalance. The traditional sedimentation treatment method has low removal efficiency for small, light and difficult-to-settle paper fibers and colloidal particles, and it is difficult to meet the subsequent treatment or discharge standards. Therefore, the wastewater must be treated by multi-stage treatment to achieve effective purification and resource utilization. The dissolved air flotation machine is widely used in the pretreatment link of paper straw production wastewater as a high-efficiency solid-liquid separation equipment.

[0003] However, the existing air flotation machine dissolves a large amount of fine bubbles into water, so that the bubbles adhere to the surface of the suspended particles to form a particle-bubble complex, which rapidly floats to the liquid surface due to its lower density than water, and is cleaned by a scum cleaning mechanism, thereby realizing efficient removal of water pollutants. During use of the existing air flotation machine, the scum on the surface of the water layer in the scum suspension separation area is cleaned by a hanging plate. During the cleaning process, the heavier solids in the scum will sink and fall in the water layer and accumulate at the bottom. At the same time, these sediments are easily attached to the inner wall during the falling process. When the sediment accumulates too much, the clean water discharged from the clean water pipeline contains a large amount of sediments, which cannot meet the discharge standard, so that the existing equipment needs to be cleaned and dredged to maintain the inner wall and bottom of the scum suspension separation area after a certain period of use, thereby affecting the operation stability and economy of the equipment.

[0004] In view of the above problems, it is necessary to make innovative design on the basis of the original. SUMMARY

[0037] Based on example one, please refer to Figures 1 to 10The dredging assembly 15 is arranged between the mounting seat 14 and the cleaning assembly 13, and the dredging assembly 15 comprises a first sliding groove 151 and a second sliding groove 153. The first sliding groove 151 and the second sliding groove 153 are transversely arranged on the right side of the mounting seat 14. The second sliding groove 153 is arranged above the flow guide groove 141, and the first sliding groove 151 is arranged above the second sliding groove 153. The first sliding groove 151 is transversely slidably connected with a sliding plate one 152.

A plurality of holes are transversely arranged in the interlayer of the mounting seat 14 between the first sliding groove 151 and the second sliding groove 153. The holes in the sliding plate one 152 and the sliding plate two 154 correspond to the clamping holes in the mounting seat 14. The size of the sliding plate one 152 corresponds to the size of the sliding plate two 154. The holes in the sliding plate one 152 are designed as a triangular structure. The triangular structure of the holes in the sliding plate one 152 is used for collecting the sediments. The holes in the sliding plate one 152 and the sliding plate two 154 correspond to the clamping holes in the mounting seat 14. The initial positions of the holes in the sliding plate one 152 and the sliding plate two 154 are staggered. A connecting rod 155 is slidably arranged at the front side of the first sliding groove 151 and the second sliding groove 153. The connecting rod 155 is connected with the bottom of the mounting box 131 through the interlayer of the front wall of the machine body 1. An adjusting head 156 is slidably arranged in the hole of the connecting rod 155. A resisting block 157 is horizontally arranged at the right side of the hole of the adjusting head 156. The resisting block 157 is fixed on the front wall of the sliding plate one 152. The left side of the resisting block 157 and the bottom of the adjusting head 156 are designed as inclined surfaces. The inclined surface of the left side of the resisting block 157 and the inclined surface of the bottom of the adjusting head 156 are used for adjusting the position of the adjusting head 156. The inclined surface of the bottom of the adjusting head 156 corresponds to the front side of the protruding block of the sliding plate two 154. The dredging assembly 15 is used for cleaning the sediments at the bottom of the water tank 6.

[0038] In use, the triangular structure between the holes of the sliding plate one 152 is arranged to guide the falling sediments in the water tank 4 into the interlayer of the mounting seat 14.

[0039] Through the reciprocating sliding of the installation box 131, and through the reciprocating cleaning of the scum and the inner wall of the separation cabin 4 by the push plate 133 and the scraping strip 134, the connecting rod 155 and the adjusting head 156 are synchronously driven to reciprocate left and right, and the corresponding resistance to the front side protrusions of the sliding plate one 152 and the sliding plate two 154 is cooperated to slide, so that when the adjusting head 156 moves from left to right, the bottom slope of the adjusting head 156 is matched with the front side protrusions of the sliding plate two 154 to resist, and the connecting rod 155 is upwardly slid in the opening, and when the front side protrusions of the sliding plate one 152 are resisted, the sliding plate one 152 is driven to form a dislocation closing state in the interlayer opening of the mounting seat 14, and when the adjusting head 156 moves to the left, the sliding plate two 154 is driven to coincide with the interlayer opening of the mounting seat 14 to open, so that the precipitates in the interlayer opening of the mounting seat 14 are discharged into the sludge tank 142, and the adjusting head 156 is cooperated with the resistance block 157 to separate from the front side protrusions of the sliding plate two 154, and the sliding plate two 154 is reset by the spring after losing the resistance, so that the interlayer opening of the mounting seat 14 is closed, the sliding plate one 152 is continuously moved to the right to reset by the resistance block 157, and the interlayer opening of the mounting seat 14 is opened, so that the collection of the precipitates is performed again.

[0040] Working principle: when the wastewater multi-stage treatment device based on paper straw processing is used, first, the operator opens the adjusting valve, and through the pipeline, the wastewater is sent into the reaction cabin 2, and then the corresponding coagulant is added into the reaction cabin 2 through the reagent feeding mechanism, and the stirring mechanism 8 and the air explosion mechanism 7 are opened, the wastewater and the coagulant in the reaction cabin 2 are uniformly stirred and reacted by the stirring mechanism 8, and then gradually flow into the air floatation cabin 3 through the opening of the partition plate between the reaction cabin 2 and the air floatation cabin 3, at this time, the solid waste coagulated by the coagulant in the wastewater is synchronously floated to the liquid surface to form scum with the micro bubbles in the air floatation cabin 3, and the separated clear water in the lower layer of the separation cabin 4 flows into the clear water cabin 6 through the pipeline, and then is discharged from the upper pipe opening in the clear water cabin 6;

[0041] When the liquid surface scum increases to flow into the separation cabin 4, at this time, the operator opens the motor one 10 through the control box, the motor one 10 drives the reciprocating screw rod 11 to rotate, and the sliding block one 12 moves left and right in the mounting frame 9, in this process, when the sliding block one 12 moves from the leftmost end to the right, the installation box 131, the sliding block two 132, the push plate 133 and the scraping strip 134 are synchronously driven to move to the right, the sliding block two 132 moves to the right through the limiting guidance of the guide block 136, so that the outer side protruding column of the sliding block two 132 moves to the right in the lower section of the track groove of the sliding groove plate 135, at this time, the position of the sliding block two 132 in the installation box 131 makes the push plate 133 keep the corresponding position with the liquid surface of the separation cabin 4, and the scum on the liquid surface of the separation cabin 4 is scraped into the sludge cabin 5 by moving to the right, and at the same time, when the scraping strip 134 moves to the right, the scum and the attachments adhered to the inner wall of the separation cabin 4 are cleaned through the sliding of the scraping strip 134 adhered to the inner wall of the separation cabin 4;

[0042] On the basis of the above, when the installation box 131 moves to the right end on the reciprocating screw 11, the outer side protruding column of the slider two 132 slides to the right end in the track groove of the sliding groove plate 135, and is reset by the spring in the installation box 131, pushes the slider two 132 to move upward in the track groove of the sliding groove plate 135 to the upper segment track groove, and drives the adjusting plate 133 to adjust the position upward, at this time, with the rotation of the reciprocating screw 11, the slider one 12 drives the installation box 131, the slider two 132 and the adjusting plate 133 to start moving to the left, when the slider two 132 moves to the inclined position in the upper segment track groove of the sliding groove plate 135, gradually extrudes the spring to shrink in the installation box 131, and in the process of the slider two 132 moving to the lower segment track of the sliding groove plate 135, the outer side protruding column of the slider two 132 extrudes the spring downward by resisting the guide block 136, and after the slider two 132 completely shrinks to the lower segment track of the sliding groove plate 135, the guide block 136 loses resistance and resets by the spring, at the same time, in this process, when the scraping strip 134 moves to the left, it cleans the inner wall of the separation cabin 4 again, achieving the effect of reciprocating cleaning;

[0043] On the basis of the above, because the initial positions of the front and rear sliders one 12 are set in opposite directions, in the above process, the front and rear cleaning assemblies 13 operate relatively, and through the guide adjustment of the slider two 132 along the track groove on the sliding groove plate 135, the front and rear adjusting plates 133 are always in staggered positions in the process of reciprocating sliding to clean the scum, so that the inner wall of the separation cabin 4 is cleaned reciprocally while the scum is cleaned;

[0044] In the above, when the left side slider one 12 drives the installation box 131 to move to the left, it synchronously drives the connecting rod 155 to move to the left, in this process, when the adjusting head 156 below the connecting rod 155 moves to the left to resist the front side protruding block of the sliding plate two 154, through the bottom inclined surface of the adjusting head 156, the adjusting head 156 moves upward in the front side hole of the connecting rod 155, and resets after passing the front side protruding block of the sliding plate two 154, when the adjusting head 156 moves to resist the front side protruding block of the sliding plate one 152, it drives the sliding plate one 152 to move to the left, and when the slider one 12 moves to the maximum position to the left, the sliding plate one 152 synchronously completes the adjustment, at this time, the hole on the sliding plate one 152 is closed in staggered position with the sandwich hole of the mounting seat 14, when the slider one 12 moves to the right, when the adjusting head 156 moves to resist the front side protruding block of the sliding plate two 154, it drives the sliding plate two 154 to move to the left, so that the hole on the sliding plate two 154 coincides with the sandwich hole of the mounting seat 14, so that the deposits in the sandwich hole of the mounting seat 14 flow into the sewage groove 142 with the water flow through the flow guide groove 141, and the deposits and scum in the sewage groove 142 are sucked away for treatment by the wastewater treatment mechanism;

[0045] In the above process, when the adjusting head 156 moves against the front side protrusion of the second sliding plate 154, the hole on the adjusting head 156 is synchronized with the left side slope of the abutting block 157, and in the moving process, the adjusting head 156 is moved upward in the hole of the connecting rod 155 by the abutting of the left side slope of the abutting block 157, and after the left side slope of the abutting block 157 is completely inserted into the hole of the adjusting head 156, the adjusting head 156 is no longer moved against the front side protrusion of the second sliding plate 154, the second sliding plate 154 is reset in the second sliding groove 153 by the spring pulling, and is again staggered closed with the interlayer hole of the mounting seat 14, the bottom sediment discharge treatment of the separation cabin 4 is completed, then the adjusting head 156 continues to move right, and drives the first sliding plate 152 to move right to reset, so that the first sliding plate 152 is coincided with the interlayer hole of the mounting seat 14 to open, and the triangular horizontal strip between the holes of the first sliding plate 152 guides the falling sediment in the water in the separation cabin 4 into the interlayer of the mounting seat 14, and the sediment discharge operation is performed again when the connecting rod 155 slides next time.
