Description

Technical Field

[0001] The present invention relates to the technical field of multi-stage treatment of textile wastewater, and in particular to a textile wastewater treatment device. Background Art

[0002] Textile machines, also known as spinning machines, looms, and cotton spinning machines, often require the addition of water to the fabric during operation to ensure fabric quality. Because textiles are often contaminated with chemicals, the addition of water inevitably washes away these chemicals, making the resulting water polluting.

[0003] There are also many short fibers and floating substances mixed in the sewage. Therefore, in order to reduce the pollution of sewage discharge to the environment, the sewage needs to be treated uniformly. Due to the characteristics of textile sewage, a phased combination of physical, chemical, biological and other processes is adopted to achieve multi-stage treatment of textile sewage, which can significantly improve the treatment efficiency of textile sewage.

[0004] As textile machines operate, floating debris in textile wastewater gradually accumulates and clogs the physical filtration equipment, preventing it from functioning properly over time and requiring regular manual cleaning and maintenance. Existing technologies typically use a cleaning mechanism to automatically clean the filter screen regularly to ensure the proper functioning of the physical filtration equipment. However, after the cleaning mechanism completes its cleaning operation, the floating debris and short fibers it removes adhere to the cleaning mechanism, making it difficult to dispose of them uniformly in a collection area. Consequently, the cleaning effect deteriorates over time, eventually becoming ineffective and requiring manual cleaning and maintenance.

[0005] In view of the deficiencies in the above-mentioned related technologies, a textile wastewater treatment equipment is proposed to solve the above-mentioned problems. Summary of the Invention

[0006] In order to solve the technical problems raised in the background technology, the present invention provides a textile wastewater treatment device.

[0007] The present invention is implemented by the following technical solution: a textile wastewater treatment device, comprising a filtering component and an agitating component connected in sequence from top to bottom, the two components being connected in the middle;

[0008] The filter assembly includes an inlet cavity and a filter screen arranged in the inlet cavity. The top and one side of the inlet cavity are opened. An inlet pipe is connected to one side of the inner wall of the inlet cavity. The filter screen is located below the inlet pipe. A cleaning unit is provided between the inlet pipe and the filter screen. A detachable collection unit is provided at the side opening of the inlet cavity, which is used to clean the garbage blocking the filter screen and collect the garbage simultaneously.

[0009] As a further improvement of the above scheme, the cleaning unit includes an upper inclined block and a lower inclined block, which are respectively fixedly connected to the upper and lower inner walls of the inlet cavity and located below the input pipe. A slot is formed between the upper inclined block and the lower inclined block. The slot is plugged into the filter screen. The other side of the filter screen extends toward the opening on one side of the inlet cavity, and the filter screen is arranged to be inclined upward outward from the slot, so as to guide the sewage to accumulate at the lower end of the filter screen.

[0010] The top end of the sliding plate is provided with a circle, and the bottom end of the sliding plate is symmetrically fixedly connected to the positioning plate, and the circular hole is symmetrically provided on both sides of the circular rod, and the inner strip is horizontally slidably connected in the side notch of the side notch, and the outer strip is fixedly connected to the sliding cylinder, and a plurality of scraping claws are fixedly connected to the bottom end of the sliding cylinder, and the scraping claws moveably to the opening at the bottom end of the horizontal plate through the abutment of the oblique block. When the cam is in contact with the sliding plate, the sliding plate is fixed with the sliding hole of the round rod to prevent the round rod from sliding at will.

[0011] The two gears are connected with each other through the two guide wheels, and the two guide wheels are connected with each other through the two guide wheels, and the two guide wheels are connected with each other through the two guide wheels, and the two guide wheels are connected with each other through the two guide wheels. The other end of the rod is fixedly connected to the connecting plate, and is used for driving the entire connecting plate to slide horizontally along the slide groove when the driven gear rotates, so as to clean the garbage stuck on the hard burrs. The cross plate is fixedly connected to the outside of the cross plate, and the rack plate is meshed with the driving gear when it moves to the outermost side, and drives the entire rotating roller to rotate outward when it makes initial contact, so as to clean the garbage at the scraper claw, and as the cross plate returns, the rotating roller will rotate toward the blocking plate and clean the rubber protrusion. The outer sides of the two sliding blocks are fixedly connected to the limit frame plates, and the inner sides of the two limit frame plates are inserted with limit plugs. The limit plugs are two groups and are symmetrically slidably connected to both sides of the outer wall of the introduction cavity. The limit plug at the lower end is used to lock the position of the sliding block cleaning state, and the limit plug at the upper end is used to lock the sliding block for manual cleaning. Fixed plugs are symmetrically fixedly connected to both sides of the outer wall of the introduction cavity, and a collection drawer is inserted and connected at the two fixed plugs. The collection drawer is located directly below the rotating roller.

[0012] As a further improvement of the above scheme, the stirring assembly includes a stirring motor fixedly connected to the outer wall of the stirring chamber coaxially, the output end of the stirring motor is located in the stirring chamber and is fixedly connected to a stirring roller, the other end of the stirring roller is rotatably connected to the inner wall of the stirring chamber, a sealing rubber ring is provided at the connection between the output end of the stirring motor and the stirring chamber, and an output pipe is connected to one side of the bottom end of the outer wall of the stirring chamber.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The present invention utilizes a cleaning unit to push the filtered fibers, and pushes them to the outside to be cleaned by a collecting unit and collected in a collecting drawer, thereby effectively ensuring the filtering effect of the filter net, avoiding clogging of the filter net due to short fiber garbage in the pollutants, improving the filtering effect of the equipment, and reducing the maintenance frequency.

[0015] (2) The present invention utilizes a filter screen that is tilted and snap-connected, which can be quickly replaced. The filter screen in the tilted state can better clean the sewage, and in conjunction with the cleaning unit, it can prevent the water from spreading outside the equipment due to blockage.

[0016] (3) The present invention utilizes a rodless cylinder to drive the entire horizontal plate to slide above the filter screen, thereby pushing the garbage sediment in the initial process and avoiding contact with the garbage in the return process, thereby ensuring that the garbage will not be pushed to the bottom of the filter screen, reducing the difficulty of cleaning.

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example 1: Please combine Figures 1-6 , a textile wastewater treatment device of this embodiment includes a filtering component and an agitating component connected in sequence from top to bottom, and the middle parts of the two components are connected;

[0030] The filter assembly includes an inlet cavity 1 and a filter screen 9 arranged in the inlet cavity 1. The top and one side of the inlet cavity 1 are opened. An inlet pipe 6 is connected to one side of the inner wall of the inlet cavity 1. The filter screen 9 is located below the inlet pipe 6. A cleaning unit is provided between the inlet pipe 6 and the filter screen 9. A detachable collection unit is provided at the side opening of the inlet cavity 1, which is used to clean the garbage blocking the filter screen 9 and collect the garbage simultaneously.

[0031] The cleaning unit includes an upper oblique block 7 and a lower oblique block 8, which are respectively fixedly connected to the upper and lower inner walls of the introduction cavity 1 and located below the input pipe 6. A slot is formed between the upper oblique block 7 and the lower oblique block 8. The slot is plugged into and connected to the filter screen 9. The other side of the filter screen 9 extends toward the opening direction of one side of the introduction cavity 1, and the filter screen 9 is arranged to be inclined upward outward from the slot, so as to guide the sewage to accumulate at the lower end of the filter screen 9.

[0032] Specifically, the upper inclined block 7 is used to guide the sewage into the filter screen 9 in an inclined state and perform preliminary filtration.

[0033] The cleaning unit includes a slide bar 12 and a slide bar 2 13 which are fixedly connected to both sides of the inner wall of the introduction chamber 1 in sequence. The slide bar 12 and the slide bar 2 13 are arranged along the length direction of the filter screen 9. The inner sides of the slide bar 12 and the slide bar 2 13 are respectively provided with a slide groove opening 14 and a slide groove opening 2 16. The opposite sides of the slide groove opening 14 and the slide groove opening 2 16 are respectively provided with an abutting oblique block 15 and an abutting oblique block 2 17. The slide bar 12 and the slide bar 2 13 are respectively slidably connected to a sliding cylinder 18. The middle part of the two sliding cylinders 18 is fixedly connected to a horizontal plate 19. The bottom of the horizontal plate 19 is open, and circular holes are opened on both sides of the horizontal plate 19. The bottom of the horizontal plate 19 is symmetrically fixed with positioning plates 20 on both sides. Round rods 21 are slidably connected in the circular holes and the positioning plates 20. Side notches 22 are symmetrically opened on both sides of the round rods 21. The inner strips 23 are horizontally slidably connected in the side notches 22. The inner strips 23 are fixedly connected with slide cylinders 24 on the outside. Several scraping claws 27 are fixedly connected to the bottom end of the slide cylinder 24. The scraping claws 27 move at the opening at the bottom end of the horizontal plate 19 and perform circular scraping by abutting against the oblique block 15 and the abutting against the oblique block 2 17. The rod 21 slides horizontally, and the two ends of the round rod 21 are intermittently connected in the sliding groove 14 and the sliding groove 2 16. A damping rubber is provided at the sliding position of one side of the horizontal plate 19 and the round rod 21 to prevent the round rod 21 from sliding at will. A ball block 25 is fixedly connected to the circular hole on the other side of the horizontal plate 19. A spiral groove 26 is provided on the outer wall of one side of the round rod 21. The spiral groove 26 is slidably connected to the ball block 25. When the horizontal plate 19 reciprocates horizontally along the slide rod 12 and the slide rod 2 13, further, the slide rod 12 and the slide rod 2 13 are moved along the horizontal plate 19. The filter screen 9 is arranged in the length direction; when the round rod 21 is able to perform horizontal displacement under the abutment of the abutting inclined block 15 and the abutting inclined block 2 17, the scraping claw 27 will be able to flip outward when the entire horizontal plate 19 returns under the sliding of the ball block 25 and the spiral groove 26, so that the scraping claw 27 at the bottom end is away from the filter screen 9, avoiding pushing the garbage at the filter screen 9 during the return journey. When reaching the innermost part, the scraping claw 27 will slide horizontally with the round rod 21, and the bottom end of the scraping claw 27 will be abutted against the upper part of the filter screen 9, and the garbage sediment will be cleaned out during sliding.

[0034] Specifically, the slide bar 12, the slide bar 2 13 and the sliding cylinder 18 are rodless cylinders, which drive the entire cross plate 19 to move back and forth. The sliding cylinder 18 is a rodless cylinder (such as SMC MGPM series).

[0035] The implementation principle of a textile wastewater treatment device in the embodiment of the present application is:

[0036] As the pump body inputs the sewage into the cavity 1 along the input pipe 6, the two sliding cylinders 18 are started to drive the cross plate 19 to slide outward along the slide bar 12 and the slide bar 2 13. At this time, the scraper claw 27 is in a state of abutting the top of the filter screen 9, and as the cross plate 19 slides outward, the fiber material can be pushed to the outside, and when the sliding cylinder 18 slides along the slide bar 12 to abut the inclined block 15, it will push the round rod 21 to slide to the other side at the inclination of the abutting inclined block 15, and as the round rod 21 rotates, the scraper claw 27 will contact the rubber protrusion 37 rotating counterclockwise. At this time, the rack plate 34 will be meshed with the driving gear 33 and pick up the garbage. Then the sliding cylinder 18 will return, and the scraper claw 27 will rotate clockwise. Figure 8 After the rotation direction of the middle rotating roller 35 rotates, the scraping claw 27 will be away from the bottom end of the filter screen 9, avoiding the return journey and the garbage filtered by the filter screen 9 to be pushed, and then the cleaning and pushing operation is performed again.

[0037] Example 2: Combination Figures 1-4 as well as Figure 7-Figure 9 Based on Example 1, this embodiment has the following further improvements:

[0038] The collecting unit includes vertical slots 28 symmetrically opened vertically on the outer wall of one side of the inlet cavity 1. The two vertical slots 28 are respectively connected to sliding blocks 29 in vertical sliding manner. The two sliding blocks 29 are connected to a rotating rod 1 30 and a rotating rod 2 31 on both sides, which are rotated from top to bottom in sequence. The rotating rod 1 30 is located on the outer wall inside the two sliding blocks 29 and is fixedly connected to a driven gear 1 32 and a driving gear 33 in sequence. The bottom end of the driven gear 1 32 is meshed with the driven gear 2 36. The driven gear 2 36 is coaxially fixedly connected to the rotating rod 2 31. The rotating rod 2 31 is located inside the two sliding blocks 29 and is fixedly connected to a rotating roller 35. The outer wall of the rotating roller 35 is fixedly connected with multiple rubber protrusions 37 in an orderly manner.

[0039] The bottom ends of the two sliding blocks 29 are provided with sliding grooves, and slides 38 are slidably connected in the two sliding grooves. Connecting plates 39 are fixedly connected to the outside of the two slides 38, and blocking plates 40 are fixedly connected to the inside of the connecting plates 39 in sequence. A number of hard thorns 41 are evenly fixedly connected to the bottom end of each blocking plate 40, which are used to clean and block the rubber protrusions 37 that are entangled with garbage.

[0040] A ring-shaped undulating groove 43 is provided on one side of the driven gear 2 36 , and a guide rod 42 is slidably connected in the undulating groove 43 . The other end of the guide rod 42 is fixedly connected to the connecting plate 39 , which is used to drive the entire connecting plate 39 to slide horizontally along the slide groove when the driven gear 2 36 rotates, so as to clean up the garbage stuck to the hard protrusion 41 .

[0041] Specifically, the guide rod 42 that slides back and forth at the wave groove 43 is affected by the sliding distance, thereby driving the entire connecting plate 39 to slide back and forth relatively horizontally, and causing an oscillation effect on the blocking plate 40.

[0042] The rack plate 34 is fixedly connected to the transverse plate 19 toward the outside. When the rack plate 34 moves to the outermost side, it engages with the driving gear 33 and drives the entire rotating roller 35 to rotate outward when it makes initial contact, thereby cleaning the garbage at the scraper claw 27. When the transverse plate 19 returns, the rotating roller 35 will rotate the garbage toward the blocking plate 40 and clean the rubber protrusion 37.

[0043] Specifically, please refer to Figure 8 During the initial journey, as the rack plate 34 is meshed with the driving gear 33, the rotating roller 35 will rotate counterclockwise in the current view and pick up the garbage at the scraper claw 27. Then, as the cross plate 19 returns, the rotating roller 35 will rotate clockwise and the picked up garbage will enter the hard thorn 41 for cleaning. Then, as the connecting plate 39 slides back and forth horizontally, the garbage at the hard thorn 41 can be vibrated and dropped.

[0044] The outer sides of the two sliding blocks 29 are fixedly connected to the limit frame plate 44, and the inner sides of the two limit frame plates 44 are connected with the limit plug blocks 45. The limit plug blocks 45 are two groups and are symmetrically slidably connected to the two sides of the outer wall of the introduction cavity 1. The limit plug block 45 located at the lower part is used to lock the position of the sliding block 29 in the cleaning state, and the limit plug block 45 located at the upper part is used to lock the sliding block 29 to facilitate manual cleaning.

[0045] Fixed plug blocks 10 are symmetrically fixedly connected to both sides of the outer wall of the introduction cavity 1 , and collecting drawers 11 are inserted and connected to the two fixed plug blocks 10 . The collecting drawers 11 are located directly below the rotating roller 35 .

[0046] The implementation principle of a textile wastewater treatment device in the embodiment of the present application is:

[0047] The vertical slot 28 can be used to quickly disassemble and install the sliding block 29, so as to facilitate cleaning and maintenance after use. The height of the sliding block 29 can be limited by two limit plugs 45 of different heights. When the collection unit is in operation, the sliding block 29 needs to be placed on the limit plug 45 at the bottom and locked. Then, the rodless cylinder is used to drive the entire horizontal plate 19 to slide outward along the slide bar 12 and the slide bar 2 13. Then, the scraper claw 27 drives the tissue accumulated on the top of the filter screen 9 to approach the collection drawer 11. At the same time, as the rack plate 34 contacts the driving gear 33, the driven gear 1 32 and the driven gear 2 36 are meshed and connected, the driving rotating roller 35 can be rotated counterclockwise, and the garbage at the scraper claw 27 can be quickly picked up and separated from the scraper claw 27 through the rubber protrusion 37. Then, the picked scraper claw 27 will not rotate with the blocking plate 40 after rotating counterclockwise, and when the rodless cylinder returns, it will drive the rotating roller 35 to rotate clockwise, so that the rubber protrusion 37 drives the adhered garbage into the hard protrusion 41.

[0048] As the driven gear 2 36 rotates, the entire connecting plate 39 slides back and forth along the slide groove by utilizing the sliding connection between the wave notch 43 and the guide rod 42, thereby driving the blocking plate 40 to vibrate back and forth, so that the garbage adhered to it enters the collection drawer 11 for collection under the vibration.

[0049] Example 3: Combination Figure 1-Figure 3 Based on Example 1 and Example 2, this embodiment has the following further improvements:

[0050] The stirring assembly includes a stirring motor 3 fixedly connected to the outer wall of the stirring chamber 2 and coaxially. The output end of the stirring motor 3 is located in the stirring chamber 2 and is fixedly connected to a stirring roller 4. The other end of the stirring roller 4 is rotatably connected to the inner wall of the stirring chamber 2. A sealing rubber ring is provided at the connection between the output end of the stirring motor 3 and the stirring chamber 2, and an output pipe 5 is connected to one side of the bottom end of the outer wall of the stirring chamber 2.

[0051] Specifically, textile wastewater contains dyes such as reactive dyes, disperse dyes, slurries such as polyvinyl alcohol (PVA), surfactants and other difficult-to-degrade organic matter, which need to be decomposed or aggregated through chemical oxidation or coagulation and precipitation. The agents include but are not limited to coagulants and flocculants, oxidants, adsorbents and decolorizers, heavy metal treatment agents, pH regulators, etc. The type of agent to be used depends on the characteristics of the textile wastewater that needs to be purified. The mixed liquid can be introduced into the upper part of the cavity 1 and then dropped from the filter screen 9 into the stirring cavity 2 for stirring. After sufficient mixing, the output pipe 5 is opened to release it to the sedimentation tank for precipitation, and then the sewage is discharged after disinfection and testing.

[0052] The implementation principle of a textile wastewater treatment device in the embodiment of the present application is:

[0053] The sewage is input into the filter screen 9 from the input pipe 6, and the sewage filtered by the filter screen 9 will enter the stirring chamber 2. When the water volume in the stirring chamber 2 reaches a certain water level (for example, more than 70% of the water level in the stirring chamber 2) as sensed by the sensor, the device issues a prompt including but not limited to an external intermittent voice prompt, and the liquid mixed with the chemical agent is poured into the stirring chamber 2 from the top of the inlet chamber 1, and then the stirring motor 3 is started to drive the stirring roller 4 to stir and mix the sewage and chemical agent in the stirring chamber 2. After sufficient mixing, the valve at the output pipe 5 is opened to discharge the internal mixture into the sedimentation area for sedimentation.

[0054] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
