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. When the existing air flotation machine is used, 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 the inner wall and bottom of the scum suspension separation area need to be cleaned and dredged for maintenance after the existing equipment is used for a certain period of time, 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

[0005] The purpose of the present application is to provide a multi-stage wastewater treatment device based on paper straw processing to solve the problems raised in the background art.

[0010] Preferably, the initial position of the sliding block on the rear side is located at the leftmost end of the rear reciprocating screw, and the initial position of the sliding block on the front side is located at the rightmost end of the front reciprocating screw.

[0011] Preferably, the cleaning assembly comprises a mounting box and a sliding groove plate, the mounting box is fixed on the inner side of the sliding block, a scraping strip is fixed on the inner side wall of the mounting box, a sliding block is slidably connected to the inner side of the mounting box through a spring, a pushing plate is fixed on the inner side wall of the sliding block, the sliding groove plate is fixed on the top of the mounting rack, the sliding groove plate is slidably connected to the sliding block through a track groove formed on the inner side, and a guide block is rotatably installed on the left side of the track groove of the sliding groove plate through a spring.

[0012] Preferably, the left side of the guide block is designed as a slope structure, and the slope structure of the guide block is used for facilitating the sliding adjustment of the sliding block.

[0013] Preferably, the dredging component includes a first chute and a second chute, which are laterally opened on the right side of the mounting base. The second chute is located above the guide channel, and the first chute is located above the second chute. A sliding plate is laterally slidably installed in the first chute, and a sliding plate is laterally slidably connected to the second chute via a spring. A connecting rod is slidably installed at the front protrusion position of the first and second chutes. The connecting rod passes through the front wall interlayer of the machine body and connects to the bottom of the mounting box. An adjusting head is slidably connected in the opening at the lower end of the connecting rod. An abutment block is horizontally arranged on the right side of the opening position of the adjusting head, and the abutment block is fixed to the right side of the front wall of the first sliding plate.

[0014] Preferably, the interlayer between the first and second slide grooves in the mounting base has multiple openings arranged laterally, the openings on the first and second slide plates correspond to the clamping openings of the mounting base, and the size of the first slide plate corresponds to the size of the second slide plate.

[0015] Preferably, the inner side opening of the slide plate is designed as a triangular structure. The triangular structure of the inner opening of the slide plate is used for the collection of sediment. The openings on the slide plate and the slide plate 2 correspond to the clamping openings of the mounting base. The initial positions of the openings on the slide plate and the slide plate 2 are staggered.

[0016] Preferably, the left side of the abutment block and the bottom of the adjusting head are both designed as inclined structures. The inclined structure on the left side of the abutment block and the inclined structure at the bottom of the adjusting head are both used for adjusting the position of the adjusting head.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention, by setting a reciprocating screw to drive a slider one to slide back and forth on the mounting frame, and coordinating the opposite initial positions of the slider one on the front and rear reciprocating screws, and guiding the vertical position of the slider two through the track groove on the slide plate, allows the two scrapers to alternately clean the scum on the surface of the separation chamber. During this process, the scrapers simultaneously slide back and forth against the inner wall of the separation chamber to clean the deposits on the front and rear inner walls of the separation chamber. This prevents the separation chamber from needing to be shut down for cleaning due to excessive deposits on the inner wall after long-term use, reduces the maintenance frequency of the equipment, and improves the operational stability and economy of the equipment.

[0019] This invention, through the cooperation of the mounting base and the sludge removal component, allows the triangular horizontal bar between the openings of the sliding plate to guide the sediment falling from the separation chamber water into the mounting base's interlayer opening. During the reciprocating cleaning of scum and the inner wall of the separation chamber by the cleaning component, the connecting rod and adjusting head simultaneously slide left and right, correspondingly contacting the front protrusions of sliding plates one and two. As the adjusting head moves from left to right, when it contacts the front protrusion of sliding plate one, it causes sliding plate one to form a misaligned closed state with the mounting base's interlayer opening. During the leftward movement of the adjusting head, sliding plate two overlaps and opens with the mounting base's interlayer opening, allowing the sediment in the mounting base's interlayer opening to be discharged into the drain trough. Then, through the cooperation of the adjusting head's opening and the contact block, the adjusting head, via the contact block, causes sliding plate one to reset, opening the mounting base's interlayer opening again for sediment collection. This intermittent sealing cleaning reduces sediment accumulation, further lowering the equipment's maintenance frequency. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figures 1 to 10This invention provides a technical solution: a multi-stage wastewater treatment device based on paper straw processing, comprising a body 1. From right to left, the inner side of the body 1 is arranged a reaction chamber 2, a flotation chamber 3, a separation chamber 4, a sludge chamber 5, and a clear water chamber 6. The height of the partition between the separation chamber 4 and the sludge chamber 5 corresponds to the height of the partition between the flotation chamber 3 and the reaction chamber 2. The height of the partition between the flotation chamber 3 and the separation chamber 4 is lower than the height of the partition between the separation chamber 4 and the sludge chamber 5. An aeration mechanism 7 is connected to the flotation chamber 3 via pipes. A stirring mechanism 8 is installed on both the front and rear walls of the inner partition of the reaction chamber 2. 1. Mounting brackets 9 are fixed to the outer sides of both the front and rear walls. Reciprocating screws 11 are rotatably mounted on the inner sides of both mounting brackets 9. Motors 10 are connected to the left side of both reciprocating screws 11. The two motors 10 are fixed to the outer walls of the front and rear sides of the machine body 1. Slider 12 is slidably connected to the outer sides of both reciprocating screws 11. The initial position of the rear slider 12 is located at the leftmost end of the rear reciprocating screw 11, and the initial position of the front slider 12 is located at the rightmost end of the front reciprocating screw 11. Cleaning components 13 are provided on one side of each slider 12. The cleaning components 13 include mounting boxes 131. The mounting box 131 is fixed to the inward side of the sliding block 12, and a scraper 134 is fixed to the inward side wall of the mounting box 131. The inner side of the mounting box 131 is slidably connected to the sliding block 132 by a spring. A lever 133 is fixed to the inward side wall of the sliding block 132. The sliding plate 135 is fixed to the top of the mounting frame 9. The sliding plate 135 is slidably connected to the sliding block 132 by a track groove opened on its inward side. A guide block 136 is rotatably mounted on the left side of the track groove on the sliding plate 135 by a spring limit. The lower left side of the guide block 136 is designed with a sloping structure. The inclined structure of guide block 136 is used to facilitate the sliding adjustment of slider 132. The bottom of sludge tank 5 and clear water tank 6 are fixed with mounting base 14. A guide channel 141 is opened on the right side of the bottom of mounting base 14. A sewage discharge channel 142 is connected to the left side of guide channel 141. The sewage discharge channel 142 is opened on the left side of mounting base 14. The position of sewage discharge channel 142 corresponds to the bottom position of sludge tank 5. Sewage discharge channel 142 is connected to wastewater treatment mechanism through front pipe. The sludge removal component 15 is set between mounting base 14 and cleaning component 13. The sludge removal component 15 is used to clean the sediment at the bottom of clear water tank 6.

[0034] When the scum on the liquid surface increases and flows into the separation chamber 4, the motor 10 is turned on to drive the reciprocating screw 11 to rotate, and the slider 12 moves back and forth in the mounting frame 9. During this process, when the slider 12 moves from the leftmost end to the right, it simultaneously drives the mounting box 131, slider 132, lever 133 and scraper 134 to move to the right. When the slider 132 moves to the right, it is guided by the limit of the guide block 136, so that the outer protrusion of the slider 132 moves to the right in the lower section of the track groove of the slide plate 135. At this time, the position of the slider 132 in the mounting box 131 makes the lever 133 keep in the corresponding position with the liquid surface of the separation chamber 4, and scrapes the scum on the liquid surface of the separation chamber 4 into the sludge chamber 5 by moving to the right. At the same time, when the scraper 134 moves to the right, it cleans the scum and attached substances on the inner wall of the separation chamber 4 by sliding against the front and rear inner walls of the separation chamber 4.

[0035] With the initial positions of slider 12 on the reciprocating screw 11 reversed, and the slider 2 132 guided and adjusted up and down by the track groove on the slide plate 135, the two front and rear baffles 133 alternately clean the scum on the surface of the separation chamber 4, while the two baffles 133 reciprocate to clean the front and rear walls of the separation chamber 4 respectively.

[0036] Example 2

[0037] Based on Example 1, please refer to Figures 1 to 10The dredging component 15 is positioned between the mounting base 14 and the cleaning component 13. The dredging component 15 includes a first chute 151 and a second chute 153. The first chute 151 and the second chute 153 are laterally located on the right side of the mounting base 14. The second chute 153 is positioned above the guide channel 141, and the first chute 151 is positioned above the second chute 153. A sliding plate 152 is laterally slidably installed inside the first chute 151. A sliding plate 154 is laterally slidably connected inside the second chute 153 via a spring. Multiple openings are laterally arranged in the interlayer between the first chute 151 and the second chute 153 within the mounting base 14. The openings on the sliding plates 152 and 154 correspond to the clamping openings of the mounting base 14. The size of the sliding plate 152 corresponds to the size of the sliding plate 154. The horizontal strips inside the openings of the sliding plate 152 are designed with a triangular structure. The triangular structure of the horizontal strips inside the openings of the sliding plate 152 is used for collecting sediment. The openings on slide plate 152 and slide plate 2 154 correspond to the clamping openings on the mounting base 14. The initial positions of the openings on slide plate 152 and slide plate 2 154 are staggered. A connecting rod 155 is slidably installed at the front protrusion position of slide groove 151 and slide groove 2 153. The connecting rod 155 passes through the front wall interlayer of the machine body 1 and connects to the bottom of the mounting box 131. An adjusting head 156 is slidably connected in the opening at the lower end of the connecting rod 155. The adjusting head 156 has an opening. A contact block 157 is horizontally positioned on the right side of the position. The contact block 157 is fixed to the right side of the front wall of the slide plate 152. The left side of the contact block 157 and the bottom of the adjusting head 156 are both designed with a sloping structure. The sloping structure on the left side of the contact block 157 and the sloping structure at the bottom of the adjusting head 156 are both used for adjusting the position of the adjusting head 156. The position of the sloping bottom of the adjusting head 156 corresponds to the position of the front protrusion of the slide plate 2 154. The sludge removal component 15 is used to clean the sediment at the bottom of the clear water tank 6.

[0038] In use, by setting the mounting base 14 and the sludge removal component 15 together, the triangular horizontal bar between the openings of the slide plate 152 guides the sediment in the water of the separation chamber 4 into the interlayer opening of the mounting base 14.

[0039] Then, as the mounting box 131 slides back and forth, and the scum and the inner wall of the separation chamber 4 are cleaned by the lever 133 and the scraper 134, the connecting rod 155 and the adjusting head 156 are simultaneously driven to slide back and forth left and right. This is in conjunction with the corresponding sliding against the front protrusions of the sliding plate 152 and the sliding plate 2 154. As the adjusting head 156 moves from left to right, when it contacts the front protrusion of the sliding plate 2 154, it slides upward in the opening of the connecting rod 155. When it contacts the front protrusion of the sliding plate 152, it causes the sliding plate 152 to move in the interlayer opening of the mounting base 14. When the device is in a staggered closed state, as the adjusting head 156 moves to the left, it causes the sliding plate 154 to overlap with the opening of the interlayer of the mounting base 14, allowing the sediment in the interlayer opening of the mounting base 14 to be discharged into the drain trough 142. With the cooperation of the opening of the adjusting head 156 and the contact block 157, the adjusting head 156 separates from the front protrusion of the sliding plate 154. After the sliding plate 154 loses its contact, it is reset by the spring, closing the interlayer opening of the mounting base 14. With the cooperation of the contact block 157, the sliding plate 152 continues to move to the right to reset and open the interlayer opening of the mounting base 14, allowing the sediment to be collected again.

[0040] Working principle: When using this multi-stage wastewater treatment device based on paper straw processing, the operator first opens the regulating valve and sends the wastewater into the reaction chamber 2 through the pipeline. Then, the corresponding coagulant is added into the reaction chamber 2 through the reagent dosing mechanism, and the stirring mechanism 8 and the aeration mechanism 7 are turned on. After the wastewater and coagulant in the reaction chamber 2 are evenly stirred and reacted by the stirring mechanism 8, they gradually flow into the air flotation chamber 3 through the opening of the partition between the reaction chamber 2 and the air flotation chamber 3. At this time, the solid waste coagulated by the coagulant in the wastewater rises to the surface of the liquid along with the tiny bubbles in the water of the air flotation chamber 3 to form scum. The separated clear water in the lower layer of the separation chamber 4 flows into the clear water chamber 6 through the pipeline and is then discharged from the upper pipe in the clear water chamber 6.

[0041] As the scum on the liquid surface increases and flows into the separation chamber 4, the operator turns on motor 10 through the control box. Motor 10 drives the reciprocating screw 11 to rotate, causing slider 12 to move back and forth within the mounting frame 9. During this process, when slider 12 moves from the leftmost end to the right, it simultaneously drives the mounting box 131, slider 132, lever 133, and scraper 134 to move to the right. When slider 132 moves to the right, it is guided by the limit of guide block 136, causing the outer protrusion of slider 132 to move to the right in the lower section of the track groove of slide plate 135. At this time, the position of slider 132 in the mounting box 131 makes lever 133 keep in the corresponding position with the liquid surface of separation chamber 4. By moving to the right, it scrapes the scum on the liquid surface of separation chamber 4 into sludge chamber 5. At the same time, when scraper 134 moves to the right, it cleans the scum and deposits attached to the inner wall of separation chamber 4 by sliding against the front and rear inner walls.

[0042] Based on the above, when the mounting box 131 moves to the rightmost end on the reciprocating screw 11, the outer protrusion of the slider 132 slides to the rightmost end in the track groove of the slide plate 135, and is reset by the spring in the mounting box 131, pushing the slider 132 to move upward in the upper track groove of the slide plate 135, and driving the dial plate 133 to adjust its position upward. At this time, as the reciprocating screw 11 rotates, the slider 12 drives the mounting box 131, the slider 132 and the dial plate 133 to start moving to the left. When the slider 132 is in the slide groove... After the upper section of the track groove of the plate 135 moves to the inclined position, it gradually compresses the spring downward in the mounting box 131. During the process of the second slider 132 moving to the lower section of the track of the slide plate 135, the outer protrusion of the second slider 132 abuts against the guide block 136, compressing the spring downward to rotate. After the second slider 132 is completely retracted to the lower section of the track of the slide plate 135, the guide block 136 loses its abutment and is reset by the spring. At the same time, during this process, when the scraper 134 moves to the left, it cleans the inner wall of the separation chamber 4 again, achieving a reciprocating cleaning effect.

[0043] Based on the above, since the initial positions of the two sliders 12 are set opposite, the two cleaning components 13 operate relative to each other during the above process. The slider 132 is guided and adjusted by the track groove on the slide plate 135, so that the two push plates 133 are always in staggered positions during the reciprocating sliding cleaning of scum, thereby cleaning the inner wall of the separation chamber 4 while completing the scum cleaning.

[0044] In the above, when the front slider 12 moves the mounting box 131 to the left, it simultaneously moves the connecting rod 155 to the left. During this process, when the adjusting head 156 below the connecting rod 155 moves to the left and abuts against the front protrusion of the sliding plate 154, the adjusting head 156 moves upward within the opening on the front side of the connecting rod 155 via the inclined surface at the bottom, and returns to its original position after passing the front protrusion of the sliding plate 154. When the adjusting head 156 moves to abut against the front protrusion of the sliding plate 152, it moves the sliding plate 152 to the left, and the slider 12 moves to the left to its maximum position. After positioning, slide plate 152 is adjusted synchronously. At this time, the opening on slide plate 152 is misaligned with the opening in the interlayer of mounting base 14 and closed. When slide plate 12 moves to the right, when the adjusting head 156 moves and abuts against the front protrusion of slide plate 2 154, it drives slide plate 2 154 to move to the left, so that the opening on slide plate 2 154 coincides with the opening in the interlayer of mounting base 14. This allows the sediment in the interlayer opening of mounting base 14 to flow into the sewage tank 142 through the guide channel 141 along with the water flow. The sediment and scum in the sewage tank 142 are then sucked away by the wastewater treatment mechanism for treatment.

[0045] During the above process, when the adjusting head 156 moves to abut against the front protrusion of the sliding plate 154, it drives the sliding plate 154 to move to the left. Simultaneously, the opening on the adjusting head 156 abuts against the left inclined surface of the abutment block 157. During this movement, the abutment against the left inclined surface of the abutment block 157 causes the adjusting head 156 to move upwards within the opening of the connecting rod 155. After the left inclined surface of the abutment block 157 is fully inserted into the opening of the adjusting head 156, the adjusting head 156 and the front protrusion of the sliding plate 154 no longer abut against each other, and the sliding plate 154 moves accordingly. The spring pulls the material back to its original position within the second slide groove 153, and then closes again in an alternating manner with the interlayer opening of the mounting base 14, completing the sewage discharge treatment of the sediment at the bottom of the separation chamber 4. Next, the adjusting head 156 continues to move to the right, driving the sliding plate 152 to move to the right and reset, so that the sliding plate 152 coincides with the interlayer opening of the mounting base 14 and opens. With the help of the triangular horizontal bar between the openings of the sliding plate 152, the sediment falling in the water of the separation chamber 4 is guided into the interlayer of the mounting base 14, and the sewage discharge operation is performed again when the connecting rod 155 slides back and forth for the next time.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
