Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for textile auxiliary production. Background Technology

[0002] Wastewater generated during the production of textile auxiliaries typically contains high concentrations of suspended particles, chemical residues, and recalcitrant organic matter. Traditional treatment equipment generally suffers from incomplete separation of suspended solids, uneven mixing of reagents, and low settling efficiency. In existing technologies, the suspended solids filtration stage often employs static screens or centrifugal separation, which is prone to clogging and requires frequent shutdowns for cleaning. After reagent addition, mixing relies on a single agitator, making it difficult to achieve a rapid and uniform reaction between wastewater and reagents, resulting in poor flocculation. When the settling zone design is inadequate, the separation of light clarified water and heavy sludge is incomplete, affecting subsequent treatment efficiency. Furthermore, each functional module is often independently driven, resulting in high energy consumption and a fragmented structure, making it difficult to adapt to the needs of continuous production. Summary of the Invention

[0003] This invention relates to a wastewater treatment equipment for textile auxiliary production, which achieves efficient pretreatment of textile auxiliary wastewater through mechanical filtration, dual-power mixing drive and gradient separation structure, and has significant advantages in terms of thorough separation, continuous operation, energy consumption control and maintenance costs.

[0004] This invention provides a wastewater treatment device for textile auxiliary production, specifically including: a pretreatment tank; the pretreatment tank, suspended solids filter cartridge, and sedimentation mixing tank constitute a wastewater pretreatment mechanism, with the vertical inner cavity of the sedimentation mixing tank located at the bottom of the pretreatment tank cavity; a support base is provided at the lower end of the sedimentation mixing tank; and a control box is mounted on the side wall of the pretreatment tank. The upper part of the pretreatment tank is a box structure bent to one side, with one end higher than the other. A filter motor is installed on the bottom side wall of the pretreatment tank. The suspended solids filter cylinders are distributed along the upper part of the pretreatment tank. A sewage inlet pipe is located at the top of the lower end of each suspended solids filter cylinder, and a suspended solids discharge pipe is located at the upper end of each suspended solids filter cylinder, extending downwards through the side wall of the pretreatment tank. A suspended solids filtration mechanism is installed in each suspended solids filter cylinder, and the suspended solids filtration mechanism is driven by the filter motor. A suspended solids receiving plate is located below the sewage inlet pipe, and the suspended solids receiving plate is also equipped with... A suspended solids scraping assembly is used to assist in cleaning the suspended solids discharge pipe. A mixing drive frame is located below the suspended solids receiving tray, and a mixing drive mechanism is located on the mixing drive frame. The sedimentation mixing tank contains a chemical mixing mechanism and a light-heavy separation assembly. The mixing drive mechanism is used to drive the chemical mixing mechanism and the suspended solids scraping assembly. A chemical tube is horizontally located in the sedimentation mixing tank above the light-heavy separation assembly, and the chemical tube is used to deliver wastewater treatment agent into the sedimentation mixing tank. Light mass collection tanks are located at the bottom left and right ends of the pretreatment tank.

[0005] Optionally, the suspended solids filtration mechanism includes a filter shaft, a filter auger, fins, and filter holes. The filter shaft is rotatably mounted in the middle of the suspended solids filter cylinder. One end of the filter shaft is fixedly connected to the end of the rotating shaft of the filter motor. A spiral filter auger is fixedly installed on the filter shaft inside the suspended solids filter cylinder. The edge of the filter auger is always tangent to the edge of the inner cavity of the suspended solids filter cylinder. The filter auger is used to transport suspended solids in the sewage to the suspended solids discharge pipe for discharge. Filter holes are evenly distributed on the lower half of the cylinder wall of the suspended solids filter cylinder. Fins are vertically installed on the left and right ends of the cylinder wall above the filter holes. The fins are used to prevent sewage passing through the filter holes from splashing upwards out of the pretreatment tank opening.

[0006] Optionally, evenly spaced distribution heads are fixed on the reagent tube above the inner cavity of the sedimentation mixing tank.

[0007] Optionally, the light-heavy separation component includes a heavy discharge pipe, an overflow port, and baffles. The upper end of the settling mixing tank has an isosceles trapezoidal shape, wider at the top and narrower at the bottom. The width of the upper end of the settling mixing tank is greater than the diameter of the suspended solids filter cartridge. Baffles are obliquely arranged outward at the upper opening of the settling mixing tank near the left and right ends. The two ends of the baffles are fixedly connected to the two ends embedded inside the settling mixing tank. The upper end of the baffles is bent upward and covers the upper edge of the settling mixing tank. The upper ends of the settling mixing tank at the left and right ends are... Overflow ports are evenly spaced at the inlet. The agent pipe is located above the two partitions. Wastewater flowing down through the filter holes gathers in the sedimentation mixing tank cavity between the two partitions and mixes with the wastewater treatment agent sprayed from the agent pipe. The flocs settle, and the clean water passes through the gap between the partition and the inner wall of the sedimentation mixing tank cavity, and finally flows out from the overflow port. The bottom of the sedimentation mixing tank is a sloping structure that slopes downward towards the mixing drive frame. The side wall of the sedimentation mixing tank below the mixing drive frame is a heavy discharge pipe.

[0008] Optionally, the reagent mixing mechanism includes a mixing base rod, a sleeve block, and a mixing rod. The mixing base rod is horizontally inserted through the lower middle part of the sedimentation mixing tank cavity. The upper end of the mixing base rod is uniformly spaced and vertically fixed with mixing rods. The mixing rod has a flat surface with concave ends. The top of the mixing rod is directly opposite the uniformly distributed head. One end of the mixing base rod is vertically fixed with a sleeve block. The upper end of the sleeve block has a long, movable groove. The mixing drive mechanism drives the mixing base rod to reciprocate through the sleeve block. The mixing rod reciprocates horizontally in the sedimentation mixing tank.

[0009] Optionally, the lightweight manifold has a structure that is wide at the top and narrow at the bottom. A manifold inlet pipe is fixedly installed at the bottom of the lightweight manifold. The two manifold inlets converge and connect to the next-level lightweight wastewater treatment system. Lightweight wastewater passing through the overflow port enters the lightweight manifold from the cavity between the sedimentation mixing tank and the pretreatment tank inner wall, and finally flows out from the manifold inlet pipe.

[0010] Optionally, the hybrid drive mechanism includes a dual-head motor and a rocker arm. The lower end of the dual-head rotating shaft of the dual-head motor is fixedly connected to a vertical rocker arm. The end of the rocker arm is vertically provided with a dial shaft, which is slidably placed in the movable groove at the upper end of the sleeve block.

[0011] Optionally, the suspended solids scraping assembly includes a turntable, an external discharge pipe, scrapers, and latches. The turntable is rotatably installed in the groove of the suspended solids receiving plate. The lower end of the turntable's shaft is fixedly connected to the upper end of the double-headed shaft of the double-headed motor. The upper end of the turntable has a conical structure that is narrower at the top and wider at the bottom. Two scrapers are symmetrically arranged vertically upward at the edge of the turntable. The upper end of the scraper extends upward along the inner wall of the suspended solids discharge pipe. An L-shaped latch is fixedly provided at the position where the scraper connects with the lower end of the suspended solids discharge pipe. The latch is slidably locked onto the pipe opening of the suspended solids discharge pipe. The scraper is always tangent to the inner wall of the suspended solids discharge pipe during the rotation of the turntable. A downwardly angled discharge pipe is provided along the tangential direction of the suspended solids receiving plate.

[0012] This invention provides a wastewater treatment device for textile auxiliary agent production, which has the following beneficial effects: 1. The inclined suspended solids filter cylinder in this invention, in conjunction with the internal filter auger (driven by a filter motor to rotate the filter shaft), achieves dynamic filtration of wastewater at the filter holes while forcibly pushing suspended solids towards the high-end suspended solids discharge pipe, significantly improving solid-liquid separation efficiency. A unique suspended solids scraping component (a rotating disc drives a scraper, with L-shaped latches securing the pipe opening) continuously scrapes away residue from the inner wall of the suspended solids discharge pipe, completely eliminating the risk of blockage. The scraped material is guided by the conical turntable to the external discharge pipe for automatic discharge, ensuring continuous system operation.

[0013] 2. In this invention, a reagent mixing mechanism driven by a dual-head motor is installed inside the settling mixing tank: the rocker arm drives the sleeve block, which in turn drives the mixing base rod and the mixing rod on it to move horizontally back and forth. The flat concave structure of the mixing rod enhances the fluid shear force, allowing the reagent sprayed from the reagent tube through the uniformly distributed head to mix rapidly with the sewage, significantly improving the flocculation reaction rate and thoroughness.

[0014] 3. In this invention, the trapezoidal flared structure at the top of the settling mixing tank, combined with the side partitions (the upper ends of which are bent to cover the tank opening), forms a directional overflow channel. After flocculation, the heavy sludge collects along the sloping bottom to the heavy sludge discharge pipe; the light clarified water overflows through the gap between the partition and the tank wall to the overflow port, enters the side cavity of the pretreatment tank, and then flows into the light sludge collection tank, finally being transported to the next stage system via the collection pipe. This design achieves efficient physical separation and directional diversion of light and heavy substances, avoiding cross-contamination.

[0015] 4. In this invention, the reciprocating motion of the mixing mechanism (lower output shaft) and the rotational motion of the suspended matter scraping component (upper output shaft) are synchronously driven by dual-head motors, significantly reducing energy consumption and simplifying the transmission structure. The bent body of the pretreatment box, the vertically embedded layout of the settling mixing box, and the compact distribution of the lightweight manifold box maximize the use of equipment space and facilitate workshop deployment.

[0016] 5. In this invention, the fins of the suspended solids filter cartridge effectively block sewage splashing at the filter holes, keeping the inside of the pretreatment tank clean; the hanging control box centrally regulates the operating parameters of the filter motor and the dual-head motor, improving operational convenience and system stability.

A sewage inlet pipe 301 is installed at the top of the lower end of the suspended solids filter cylinder 3, and a suspended solids discharge pipe 302 is installed at the upper end of the suspended solids filter cylinder 3, which extends downward through the side wall of the pretreatment tank 1. A suspended solids filtration mechanism is installed in the suspended solids filter cylinder 3, which is driven by the filter motor 4. A suspended solids receiving plate 9 is installed below the sewage inlet pipe 301. It is also equipped with a suspended solids scraping component for auxiliary cleaning of the suspended solids discharge pipe 302. A mixing drive frame 8 is provided below the suspended solids receiving plate 9, and a mixing drive mechanism is provided on the mixing drive frame 8.

[0023] The suspended solids filtration mechanism includes a filter shaft 303, a filter auger 304, fins 305, and filter holes 306. The filter shaft 303 is rotatably installed in the middle of the suspended solids filter cylinder 3. One end of the filter shaft 303 is fixedly connected to the end of the rotating shaft of the filter motor 4. A spiral filter auger 304 is fixedly installed on the filter shaft 303 in the inner cavity of the suspended solids filter cylinder 3. The edge of the filter auger 304 is always tangent to the edge of the inner cavity of the suspended solids filter cylinder 3. The filter auger 304 is used to transport suspended solids in the sewage to the suspended solids discharge pipe 302 for discharge. Filter holes 306 are evenly distributed on the lower half of the cylinder wall of the suspended solids filter cylinder 3. Fins 305 are vertically installed on the left and right ends of the cylinder wall above the filter holes 306. The fins 305 are used to prevent sewage passing through the filter holes 306 from splashing upwards out of the opening of the pretreatment tank 1.

[0024] Among them, the reagent tube 10 above the inner cavity of the sedimentation mixing tank 5 is uniformly fixed with a distribution head 1001 at intervals.

[0025] The light-heavy separation component includes a heavy discharge pipe 501, an overflow port 504, and baffles 505. The upper end of the settling mixing tank 5 has an isosceles trapezoidal shape, wider at the top and narrower at the bottom. The width of the upper end of the settling mixing tank 5 is greater than the diameter of the suspended solids filter cartridge 3. Baffles 505 are obliquely arranged outward at the upper opening of the settling mixing tank 5 near the left and right ends. The two ends of the baffles 505 are fixedly connected to the two ends embedded in the settling mixing tank 5. The upper end of the baffles 505 is bent upward and covers the upper edge of the settling mixing tank 5. The upper openings at the left and right ends of the settling mixing tank 5 are respectively... The chamber is evenly equipped with an overflow port 504. The agent pipe 10 is located above the two partitions 505. The sewage flowing down through the filter hole 306 is collected in the sedimentation mixing tank 5 between the two partitions 505 and mixed with the sewage treatment agent sprayed from the agent pipe 10. The flocs settle down, and the clean water passes through the gap between the partition 505 and the inner wall of the sedimentation mixing tank 5, and finally flows out from the overflow port 504. The bottom of the sedimentation mixing tank 5 is a sloping structure that slopes downward toward the mixing drive frame 8. The side wall of the sedimentation mixing tank 5 below the mixing drive frame 8 is a heavy discharge pipe 501.

[0026] The reagent mixing mechanism includes a mixing base rod 502, a sleeve block 503, and a mixing rod 506. The mixing base rod 502 is horizontally inserted through the lower middle part of the inner cavity of the settling mixing tank 5. The mixing rod 506 is evenly spaced and vertically fixed at the upper end of the mixing base rod 502. The mixing rod 506 has a flat surface with a concave middle at both ends. The top of the mixing rod 506 is directly opposite the uniform distribution head 1001. The sleeve block 503 is vertically fixed at one end of the mixing base rod 502. The upper end of the sleeve block 503 has a long strip-shaped movable groove. The mixing drive mechanism drives the mixing base rod 502 to move back and forth through the sleeve block 503. The mixing rod 506 moves horizontally back and forth in the settling mixing tank 5.

[0027] The lightweight manifold 6 has a structure that is wide at the top and narrow at the bottom. The bottom of the lightweight manifold 6 is fixed with a manifold inlet pipe 601. The two manifold inlet pipes 601 converge and connect to the next-level lightweight wastewater treatment system. Lightweight wastewater passing through the overflow port 504 enters the lightweight manifold 6 from the cavity between the inner wall of the settling mixing tank 5 and the pretreatment tank 1, and finally flows out from the manifold inlet pipe 601.

[0028] The hybrid drive mechanism includes a dual-head motor 801 and a rocker arm 802. The lower end of the dual-head rotating shaft of the dual-head motor 801 is fixedly connected to the vertical rocker arm 802. The end of the rocker arm 802 is vertically provided with a dial shaft, which is slidably placed in the movable groove at the upper end of the sleeve block 503.

[0029] In Example 2, based on Example 1, the suspended solids scraping assembly includes a turntable 901, a drain pipe 902, scraper rods 903, and latches 904. The turntable 901 is rotatably installed in the groove of the suspended solids receiving plate 9. The lower end of the rotating shaft of the turntable 901 is fixedly connected to the upper end of the double-headed rotating shaft of the double-headed motor 801. The upper end of the turntable 901 has a conical structure that is narrower at the top and wider at the bottom. Two scraper rods 903 are symmetrically arranged vertically upward at the edge of the turntable 901. The upper end of 03 extends upward along the inner wall of the suspended solids discharge pipe 302. An L-shaped latch 904 is fixed at the position where the scraper 903 connects with the lower end of the suspended solids discharge pipe 302. The latch 904 is slidably locked onto the pipe opening of the suspended solids discharge pipe 302. The scraper 903 is always tangent to the inner wall of the suspended solids discharge pipe 302 during the rotation of the turntable 901. A downwardly angled sewage pipe 902 is provided in the tangential direction of the suspended solids receiving plate 9.

[0030] The following provides further explanation and description of the functions and effects of each structure mentioned above, to help those skilled in the art better understand the technical solution: Wastewater first enters the inclined suspended solids filter cylinder 3 through the wastewater inlet pipe 301. The suspended solids filtration mechanism inside the cylinder is driven by the filter motor 4, and its key component, the filter shaft 303, drives the spiral filter auger 304 to rotate. The edge of the filter auger 304 is in close contact with the cylinder wall, forcibly pushing the suspended solids in the wastewater towards the upper suspended solids discharge pipe 302. At the same time, the wastewater flows out under pressure through the densely packed filter holes 306 in the lower half of the cylinder wall, achieving preliminary separation of suspended solids. The fins 305 set above the filter holes 306 effectively prevent possible splashing of wastewater as it passes through the filter holes 306, preventing contamination of the upper space of the pretreatment tank 1.

[0031] Wastewater passing through filter holes 306 falls into the sedimentation mixing tank 5 below. Here, the chemical tube 10 and its uniform distribution head 1001 evenly spray the wastewater treatment agent into the wastewater. To promote rapid and thorough mixing of the agent and wastewater, the equipment is equipped with a chemical mixing mechanism. The core of this mechanism is a mixing base rod 502 that runs horizontally through the sedimentation mixing tank 5, on which a specially designed flat, concave mixing rod 506 is fixed. The mixing rod 506 is located below the uniform distribution head 1001, and its reciprocating motion is driven by a mixing drive mechanism: a dual-head motor 801 drives a sleeve block 503 (fixed to one end of the mixing base rod 502) to reciprocate through its lower rocker arm 802, thereby driving the mixing base rod 502 and the mixing rod 506 to move horizontally back and forth, powerfully agitating the wastewater and the agent, and accelerating the flocculation reaction.

[0032] The mixed wastewater undergoes sedimentation and separation within the sedimentation mixing tank 5. The upper part of the sedimentation mixing tank 5 is designed as a trapezoidal structure, with outwardly inclined baffles 505 on both sides. The upper ends of the baffles 505 are bent to cover the edge of the tank opening, forming a channel with the tank wall. The heavier flocs produced by the flocculation reaction sink to the bottom of the tank, while the separated light clarified water rises and flows through the gap between the baffles 505 and the side walls of the sedimentation mixing tank 5 to the overflow ports 504 at the upper left and right ends of the tank. The bottom of the sedimentation mixing tank 5 is designed as a sloped surface sloping downwards towards the mixing drive frame 8. The collected heavy sludge is discharged through the heavy sludge discharge pipe 501 at the end of this slope. The light clarified water flowing out from the overflow port 504 enters the space between the inner wall of the pretreatment tank 1 and the outer wall of the sedimentation mixing tank 5, and flows into the light sludge collection tanks 6 located at the left and right ends of the bottom of the pretreatment tank 1. The lightweight manifold 6 has a narrow top and wide bottom structure. After collecting lightweight wastewater, it is transported to the next stage of the treatment system through the manifold 601 at its bottom.

[0033] For suspended solids discharged from the suspended solids filter cartridge 3, the equipment is equipped with a special collection and anti-clogging design. After being discharged through the suspended solids discharge pipe 302, the suspended solids fall into the suspended solids receiving tray 9 directly below it. To prevent suspended solids from accumulating on the inner wall of the suspended solids discharge pipe 302 and causing blockage, a suspended solids scraping assembly is provided. This assembly is also driven by the upper end of a dual-head motor 801: the motor drives the turntable 901 in the suspended solids receiving tray 9 to rotate, and the two scraper rods 903 vertically mounted on the edge of the turntable 901 rotate accordingly. The upper end of the scraper rod 903 extends into the suspended solids discharge pipe 302, and the L-shaped latch 904 fixed at its top is slidably engaged with the edge of the pipe opening, ensuring that the scraper rod 903 always keeps close to the inner wall of the suspended solids discharge pipe 302 during rotation, effectively scraping off the attached material. The scraped suspended solids fall into the suspended solids receiving tray 9 and are finally discharged through the drain pipe 902 that slopes downwards from the side of the tray. The entire pretreatment box 1 is stably supported by the base 7, and the operation and control are centrally managed by the control box 2 mounted on the box wall.

[0034] In summary, this equipment achieves preliminary solid-liquid separation through the suspended solids filter cartridge 3 and its internal mechanism; ensures efficient mixing of chemicals through the chemical mixing mechanism in the settling mixing tank 5; achieves physical separation and diversion of light and heavy substances (light substances to the light substance collection tank 6 and collection pipe 601, heavy substances to the heavy substance external discharge pipe 501) through the design of the baffle 505 and the overflow port 504; and uses a dual-head motor 801 to simultaneously drive the mixing and scraping actions, improving the equipment integration and operating efficiency. The coordinated operation of all components enables continuous and efficient pretreatment of wastewater from textile auxiliary agent production.

[0035] Working Principle: Wastewater first enters the inclined suspended solids filter cylinder 3 through the wastewater inlet pipe 301. The filter motor 4 is started, driving the filter shaft 303 to rotate, which in turn drives the spiral filter auger 304 on it to rotate. The edge of the filter auger 304 is in close contact with the cylinder wall, pushing the solid suspended solids in the wastewater to the upper part, and finally discharging them through the suspended solids discharge pipe 302. Simultaneously, under pressure, the wastewater seeps out through the filter holes 306 in the lower half of the cylinder wall, achieving preliminary separation of suspended solids. The fins 305 above the filter holes 306 prevent wastewater splashing, ensuring that the liquid falls directionally into the sedimentation and mixing tank 5 below. The discharged suspended solids fall into the suspended solids receiving tray 9. At this time, the upper output shaft of the dual-head motor 801 drives the turntable 901 to rotate, causing the two scraper rods 903 on its edge to rotate synchronously. The L-shaped latches 904 at the top of the scraper rods 903 are engaged with the opening of the suspended solids discharge pipe 302, ensuring that the scraper rods 903 remain in close contact with the inner wall of the pipe during rotation, continuously scraping away residual suspended solids and preventing blockage. The scraped-off suspended matter slides into the suspended matter receiving tray 9 and is discharged through the sewage pipe 902.

[0036] After the wastewater from the infiltration pore 306 enters the settling and mixing tank 5, the uniformly distributed head 1001 on the agent pipe 10 sprays the wastewater treatment agent evenly into the wastewater. Simultaneously, the lower output shaft of the dual-head motor 801 drives the sleeve block 503 (fixed to one end of the mixing base rod 502) to perform horizontal reciprocating motion via the rocker arm 802, causing the mixing base rod 502 and its vertically mounted mixing rod 506 to reciprocate in the wastewater. The flat, concave structure of the mixing rod 506 enhances the fluid shear force, promoting rapid mixing of the agent and wastewater and initiating a flocculation reaction. The mixed wastewater is then allowed to settle and separate within the settling and mixing tank 5: the upper end of the settling and mixing tank 5 has a trapezoidal flared structure, and the outwardly sloping partitions 505 on both sides form overflow channels with their inner walls. The heavy sludge produced by flocculation settles to the bottom of the tank, while the light clarified water rises and flows through the gaps between the partitions 505 and the tank walls to the overflow ports 504 on the upper left and right sides. The bottom of the settling mixing tank 5 is designed as an inclined surface sloping towards the mixing drive frame 8. The collected heavy sludge is discharged through the heavy sludge discharge pipe 501. The overflowing light clarified water enters the cavity between the inner wall of the pretreatment tank 1 and the outer wall of the settling mixing tank 5, and flows into the light sludge collection tanks 6 at the left and right ends of the bottom. The light sludge collection tanks 6 transport the clarified water to the next treatment system through the collection pipe 601 at the bottom.

[0037] Throughout the process, the dual-head motor 801 synchronously drives the horizontal reciprocating mixing motion of the mixing rod 506 and the rotating scraping action of the scraper 903, achieving integrated power. The equipment is stably supported by the base 7, and the operating parameters are centrally monitored and adjusted through the control box 2 mounted on the side wall of the pretreatment tank 1, thereby completing the continuous and efficient pretreatment of textile auxiliary wastewater from suspended solids separation, reagent mixing, flocculation sedimentation to the separation and discharge of light and heavy substances.
