Description

Technical Field

[0001] This utility model relates to the field of dyeing and printing equipment, and more specifically, it relates to a dyeing wastewater treatment device. Background Technology

[0002] Dyeing and printing is a processing method, and it is also a general term for pretreatment, dyeing, printing, finishing, washing, etc. Existing fabrics need to be washed during the pretreatment process. After washing, the fabric is prone to generating wastewater. This wastewater contains impurities such as dust and broken threads, making it impossible to wash and use it again. Therefore, it needs to be treated by wastewater treatment equipment.

[0003] Existing dyeing wastewater treatment equipment generally uses filter plates to filter impurities in the wastewater. This makes it easy for impurities to accumulate on the filter plates. When too many impurities accumulate on the filter plates, they are prone to clogging. As a result, the filter plates need to be removed from the wastewater treatment equipment after each use to clean the impurities attached to them. This leads to a high frequency of disassembly and cleaning of the filter plates by the operators, which is quite inconvenient.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dyeing wastewater treatment device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dyeing wastewater treatment device, comprising an inlet pipe and an outlet pipe fixedly connected to a treatment tank, wherein an upper partition and a lower partition arranged symmetrically are fixedly connected to the inner top wall and inner bottom wall of the treatment tank, respectively, the upper partition and the lower partition dividing the interior of the treatment tank into a filtration zone and a cleaning zone, the inlet pipe and the outlet pipe being connected to the filtration zone, a rotating shaft being rotatably connected to the inner side wall of the treatment tank, and four filter plates arranged in a circular array being fixedly connected to the outer peripheral wall of the rotating shaft, one of the filter plates being located in the filtration zone and arranged horizontally, and one of the filter plates being located in the cleaning zone and arranged horizontally, the rotating shaft being located between the upper partition and the lower partition, and a gap being formed between the upper partition and the lower partition for the filter plates to pass through, an installation frame being fixedly connected to the outer side wall of the treatment tank, and a slot communicating with the cleaning zone being opened on the treatment tank, the slot communicating with the interior of the installation frame, and a cleaning component for cleaning the filter plates located in the cleaning zone being slidably connected inside the installation frame.

[0007] Preferably, the cleaning assembly includes an upper scraper, a lower scraper, a mounting strip, and a hydraulic rod. The upper and lower scrapers are respectively disposed on the top and bottom surfaces of the mounting strip. The telescopic end of the hydraulic rod is fixedly connected to the side of the mounting strip away from the rotating shaft, and one end of the hydraulic rod is fixedly connected to the inner wall of the mounting frame. The axial direction of the hydraulic rod is perpendicular to the axial direction of the rotating shaft. The upper scraper, the mounting strip, and the lower scraper are respectively in contact with the inner wall of the groove. A cleaning channel for contacting the filter plate is formed between the upper and lower scrapers.

[0008] Preferably, the axial direction of the mounting strip is parallel to the axial direction of the rotating shaft, and dovetail strips are fixedly connected to the top and bottom surfaces of the mounting strip. Dovetail grooves for embedding the dovetail strips are provided on the bottom surface of the upper scraper and the top surface of the lower scraper. A through-hole for removing the upper or lower scraper is provided on one side of the mounting frame, and the through-hole is connected to the inside of the mounting frame.

[0009] Preferably, the length of the dovetail strip is less than the length of the mounting strip, and the dovetail strip and the mounting strip are arranged on the same plane at the same end, and the opening is opened on the side of the mounting frame away from the dovetail groove opening.

[0010] Preferably, a receiving frame is provided in the cleaning area, the horizontal height of the receiving frame is less than the horizontal height of the filter plate located in the cleaning area, and the receiving frame is respectively attached to the lower partition and the inner side wall of the processing box.

[0011] Preferably, both the lower partition and the inner wall of the processing box are fixedly connected with abutment strips for sliding the receiving frame, and a through groove connected to the cleaning area and for the receiving frame to pass through is provided on one side of the processing box.

[0012] In summary, this utility model has the following beneficial effects: This solution divides the interior of the treatment tank into a filtration zone and a cleaning zone using upper and lower partitions. A rotating shaft is installed inside the treatment tank, and four filter plates are evenly spaced in a circular array on the shaft, with one filter plate located in the filtration zone. When the operator pours wastewater into the treatment tank through the inlet pipe, the wastewater flows downwards within the filtration zone and is filtered by one of the filter plates in that zone to remove impurities. When the filter plate in the filtration zone has impurities adhering to it and needs cleaning, the rotating shaft is rotated, causing all four filter plates to rotate, thus cleaning the used and adhering impurities. The filter plate containing impurities rotates from the filtration zone to the cleaning zone. Then, the cleaning component moves it through the slot and into the cleaning zone until it cleans the filter plate in the cleaning zone that is covered with impurities. Meanwhile, one of the other clean filter plates gradually rotates into the filtration zone for use. This allows one filter plate to filter impurities in the wastewater while the cleaning component cleans the used filter plate that is covered with impurities. Filtration and cleaning can be performed simultaneously, eliminating the need for the operator to disassemble and clean the filter plate after it has filtered impurities, making it convenient for the operator to clean the filter plate.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Example:

[0020] A dyeing wastewater treatment device, such as Figures 1 to 4As shown, the treatment chamber includes an inlet pipe 2 and an outlet pipe 3 welded to the treatment chamber 1. Valves are installed on both the inlet pipe 2 and the outlet pipe 3. An upper partition 4 and a lower partition 5, symmetrically arranged, are welded to the inner top and bottom walls of the treatment chamber 1, respectively. The upper partition 4 is located directly above the lower partition 5. The upper partition 4 and lower partition 5 divide the interior of the treatment chamber 1 into a filtration zone 6 and a cleaning zone 7. Both the inlet pipe 2 and the outlet pipe 3 are connected to the filtration zone 6. A rotating shaft 8 is connected to the inner side wall of the treatment chamber 1 via a motor. The output end of the motor passes through the side wall of the treatment chamber 1 and is welded to one end of the rotating shaft 8. The motor is bolted to the outer side wall of the treatment chamber 1. Four filter plates 9 arranged in a circular array are welded to the outer periphery of the rotating shaft 8. The filter plates 9 are in contact with the inner side wall of the treatment chamber 1. Four filter plates 9 are evenly spaced on the rotating shaft 8. One filter plate 9 is located in the filtration zone 6 and is horizontally arranged. Another filter plate 9 is located in the cleaning zone 7 and is horizontally arranged. The other two filter plates 9 are vertically arranged and are respectively attached to the upper partition 4 or the lower partition 5. The rotating shaft 8 is located between the upper partition 4 and the lower partition 5. A gap is formed between the upper partition 4 and the lower partition 5 for the filter plates 9 to pass through. An installation frame 10 is welded to the outer wall of the processing box 1. The side of the installation frame 10 near the cleaning zone 7 is open. A slot 11 is opened on the processing box 1 and communicates with the cleaning zone 7. The slot 11 communicates with the inside of the installation frame 10. A cleaning component 12 for cleaning the filter plates 9 located in the cleaning zone 7 is slidably connected inside the installation frame 10.

[0021] The cleaning assembly 12 includes an upper scraper 121, a lower scraper 122, a mounting strip 123, and a hydraulic rod 124. The hydraulic rod 124 is horizontally positioned. The upper scraper 121 is located directly above the lower scraper 122. The upper scraper 121 and the lower scraper 122 are respectively mounted on the top and bottom surfaces of the mounting strip 123. The telescopic end of the hydraulic rod 124 is welded to the side of the mounting strip 123 away from the rotating shaft 8. One end of the hydraulic rod 124 is bolted to the inner wall of the mounting frame 10. The axial direction of the pressure rod 124 is perpendicular to the axial direction of the rotating shaft 8. The upper scraper 121, the mounting strip 123, and the lower scraper 122 are respectively attached to the inner wall of the slot 11. A cleaning channel for contacting the filter plate 9 is formed between the upper scraper 121 and the lower scraper 122. The axial direction of the mounting strip 123 is parallel to the axial direction of the rotating shaft 8, and dovetail strips 13 are welded to both the top and bottom surfaces of the mounting strip 123. The bottom surface of the upper scraper 121 and the top surface of the lower scraper 122 are both provided with... The dovetail groove 14 is used for embedding the dovetail strip 13. A through-hole 15 is provided on one side of the mounting frame 10 for removing the upper scraper 121 or lower scraper 122. The through-hole 15 communicates with the interior of the mounting frame 10. The length of the dovetail strip 13 is less than the length of the mounting strip 123, and the dovetail strip 13 and the mounting strip 123 are arranged on the same plane at the same end. The through-hole 15 is located on the side of the mounting frame 10 away from the opening of the dovetail groove 14. A receiving frame 16 is installed in the cleaning area 7. The top of 6 is recessed downwards. The horizontal height of the receiving frame 16 is less than the horizontal height of the filter plate 9 located in the cleaning area 7. The receiving frame 16 is attached to the inner wall of the lower partition 5 and the processing box 1 respectively. The inner wall of the lower partition 5 and the processing box 1 are both welded with abutment strips 17 for the receiving frame 16 to slide. The bottom of the receiving frame 16 is attached to the top of the abutment strips 17. A through groove 18 is opened on one side of the processing box 1, which is connected to the cleaning area 7 and is used for the receiving frame 16 to pass through.

[0022] The operator opens the valve on the inlet pipe 2 and pours the wastewater into the treatment tank 1 through the inlet pipe 2. At this time, the wastewater is located in the filtration zone 6 and flows downwards. Simultaneously, one of the filter plates 9 in the filtration zone 6 is horizontally positioned. Impurities in the wastewater are filtered through this filter plate 9. Then, the valve on the outlet pipe 3 is opened, allowing the filtered liquid to flow out for treatment. When the filter plates 9 in the filtration zone 6 are covered with impurities and need cleaning, the motor is started to drive the rotating shaft 8 to rotate clockwise. When the rotating shaft 8 rotates clockwise, it simultaneously drives all four filter plates 9 to rotate in the same direction. At this time, the used filter plates 9 are cleaned. The filter plate 9 with impurities first passes through the gap between the upper partition 4 and the lower partition 5 in the filtration zone 6 and then gradually rotates to the cleaning zone 7. Meanwhile, one of the other clean filter plates 9 rotates from the gap between the upper partition 4 and the lower partition 5 into the filtration zone 6 for use. During the rotation of the filter plate 9, the upper scraper 121, the mounting strip 123, and the lower scraper 122 are respectively in contact with the inner wall of the slot 11, and the filter plate 9 does not contact the upper scraper 121, the mounting strip 123, and the lower scraper 122 during rotation. When the filter plate 9 with impurities rotates from the filtration zone 6 to the cleaning zone 7 and is in a horizontal position, the extension end of the hydraulic rod 124 is moved, which drives the upper scraper 121, the mounting strip 123, and the lower scraper 122 respectively. The mounting strip 123 and the lower scraper 122 move away from the mounting frame 10 and gradually move into the cleaning area 7, so that the upper scraper 121, mounting strip 123, and lower scraper 122 are not in contact with the inner wall of the slot 11, until the filter plate 9 in the cleaning area 7 is located in the cleaning channel between the upper scraper 121 and the lower scraper 122. At this time, the bottom surface of the upper scraper 121 is in contact with the top surface of the filter plate 9 and cleans the impurities on the filter plate 9. At the same time, the top surface of the lower scraper 122 is in contact with the bottom surface of the filter plate 9 to scrape off the impurities. Then, by moving the telescopic end of the hydraulic rod 124, the upper scraper 121, mounting strip 123, and lower scraper 122 are respectively driven towards the inner wall of the slot 11. The filter plate 9 moves towards the mounting frame 10 until it is no longer in contact with the upper scraper 121 and the lower scraper 122. At this time, the upper scraper 121 and the lower scraper 122 scrape the impurities on both sides of the filter plate 9 off the filter plate 9 and let the impurities fall down into the collection frame 16 for collection. Thus, while one of the filter plates 9 is filtering impurities in the wastewater in the filtration zone 6, one of the filter plates 9 in the cleaning zone 7 that has been used and has impurities attached can be cleaned at the same time by the cleaning component 12. The filtration and cleaning operations can be performed at the same time, so that the operator does not need to disassemble the filter plate 9 for cleaning, which is convenient for the operator to clean the filter plate 9.

[0023] When the receiving box 16 contains a lot of impurities that need to be cleaned, the operator moves the receiving box 16 toward the direction of the through groove 18. At this time, the contact area between the bottom of the receiving box 16 and the top of the contact strip 17 gradually decreases until the receiving box 16 passes through the through groove 18, so that the receiving box 16 is removed from the cleaning area 7 and taken out of the processing box 1, and the impurities in the receiving box 16 can be processed.

[0024] When the upper scraper 121 or the lower scraper 122 needs cleaning or replacement, the telescopic end of the hydraulic rod 124 is moved, which in turn moves the upper scraper 121, the mounting strip 123, and the lower scraper 122 toward the mounting frame 10. This causes the upper scraper 121, the mounting strip 123, and the lower scraper 122 to pass through the slot 11 and gradually move into the mounting frame 10 until the upper scraper 121 and the lower scraper 122 are aligned with the opening 15. Afterward, the operator can manually move the upper scraper 121 or the lower scraper 122. The dovetail strip 13 at the top of the mounting strip 123 gradually detaches from the dovetail groove 14 at the bottom of the upper scraper 121, or the dovetail strip 13 at the bottom of the mounting strip 123 gradually detaches from the dovetail groove 14 at the top of the lower scraper 122, so that the upper scraper 121 or the lower scraper 122 can pass through the through-hole 15 and be removed from the mounting frame 10, making it convenient to clean or replace the upper scraper 121 or the lower scraper 122. The length of the dovetail strip 13 is less than the length of the mounting strip 123, which allows for quick disassembly and installation of the upper scraper 121 or the lower scraper 122.

All technical solutions falling within the scope of this utility model's concept are protected.
