Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a retractable filter frame type chemical fiber wastewater treatment device. Background Technology

[0002] The production of synthetic fibers generates a large amount of wastewater containing particulate impurities, fiber debris, and chemical additive residues. The purification and treatment of this wastewater is crucial for achieving environmentally compliant production and preventing pollution. Currently, existing synthetic fiber wastewater treatment equipment has significant technical shortcomings in the particulate impurity treatment stage. The core issues are insufficient dehydration of particulate impurities and poor ease of cleaning solid impurities. These problems directly affect wastewater treatment efficiency, environmental performance, and equipment operational continuity, failing to meet the practical application needs of the synthetic fiber production field.

[0003] Existing equipment can only perform basic filtration and interception of particulate impurities in chemical fiber wastewater, lacking an effective dewatering structure design. This results in the intercepted particulate impurities carrying a large amount of wastewater, increasing the difficulty and volume of solid impurity treatment and making it prone to wastewater leakage during impurity transfer and storage, causing secondary pollution and violating the concept of green and environmentally friendly production. Furthermore, the existing equipment's solid impurity collection structure is poorly designed, with cumbersome disassembly and inconvenient cleaning of collection components. Operation requires significant manpower and resources, and impurities are prone to scattering during cleaning, affecting operational efficiency and further exacerbating pollution risks. This hinders efficient and convenient solid impurity removal, restricts continuous operation, and makes it difficult to meet the needs of large-scale, continuous operations in chemical fiber production.

[0040] The following is in conjunction with the appendix Figure 1-9 The principles and features of the present invention are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of the invention. The invention is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] The core of this wastewater treatment equipment is used to treat the wastewater generated during the production of chemical fibers. This type of wastewater is rich in fiber debris, chemical additive residues, and fine particulate impurities. The specific structure and working process of this wastewater treatment equipment are described in detail below.

[0044] This equipment includes a frame 10, which consists of a filter barrel 11, a treatment cylinder 12, and a feed hopper 13. The feed hopper 13 is fixedly installed at the top of the filter barrel 11 to receive the chemical fiber production wastewater and treatment agents. The top of the treatment cylinder 12 is fixedly connected to the bottom of the filter barrel 11 to form a continuous channel for wastewater from filtration to reaction treatment. The filter barrel 11 is used to perform preliminary filtration of chemical fiber wastewater, intercepting fiber debris and large particulate impurities in the wastewater. The treatment cylinder 12 is used to perform the mixing reaction of chemical fiber wastewater and agents and subsequent deep treatment, degrading chemical additive residues in the wastewater.

[0045] A stirring assembly is installed on the treatment cylinder 12. The stirring assembly includes a stirring rod 50, a motor 51, and a stirring shaft 52. The motor 51 is fixedly installed on the lower surface of the treatment cylinder 12 and serves as the power source for the entire stirring assembly. The stirring rod 50 is rotatably installed inside the treatment cylinder 12. The bottom end of the stirring rod 50 is fixedly connected to the output end of the motor 51. After the motor 51 is started, it can drive the stirring rod 50 to rotate synchronously. Multiple stirring shafts 52 are provided and are fixedly installed on the outer surface of the stirring rod 50. When the stirring rod 50 rotates, it drives the stirring shaft 52 to rotate synchronously, thereby achieving full stirring of the chemical fiber wastewater inside the treatment cylinder 12. This ensures that the chemical agents are uniformly mixed with the fiber fragments and chemical auxiliaries in the wastewater, thus improving the reaction efficiency.

[0046] A filter plate 20 is rotatably mounted on the top of the processing cylinder 12. The top of the stirring rod 50 is fixedly connected to the lower surface of the filter plate 20, so that when the stirring assembly rotates, it can synchronously drive the filter plate 20 to rotate rapidly. An annular gap is formed between the edge of the filter plate 20 and the filter barrel 11. This annular gap is used for the subsequent discharge of fiber debris and particulate impurities.

[0047] A closing ring 40 is provided at the annular interval. The closing ring 40 is mounted on the treatment cylinder 12 in a height-adjustable manner to control the opening and closing of the annular interval. An electric telescopic rod 41 is fixedly installed on the outer surface of the treatment cylinder 12. The movable end of the electric telescopic rod 41 is fixedly connected to the closing ring 40. By extending and retracting the movable end of the electric telescopic rod 41, the closing ring 40 can be driven to move up and down along the treatment cylinder 12, thereby realizing the opening and closing of the annular interval and preventing the leakage of untreated chemical fiber wastewater.

[0048] Multiple filter frames are arranged above the filter plate 20, and these filter frames are evenly distributed along the circumference of the filter plate 20. A mounting column 22 is fixedly installed at the center of the upper surface of the filter plate 20, and a sliding support frame is fixedly installed at the top of the mounting column 22. Each filter frame is slidably installed on the sliding support frame, so that each filter frame can only slide along the radial direction of the filter plate 20, realizing the extension and retraction adjustment of the filter frame to adapt to different amounts of chemical fiber wastewater treatment needs.

[0049] The sliding support frame includes a first sliding rod 23 and a mounting ring 24. The mounting ring 24 is rotatably mounted on the inner surface of the filter bucket 11 and can rotate synchronously with the filter plate 20. Multiple first sliding rods 23 are provided, and each filter frame has one or more first sliding rods 23. Each first sliding rod 23 is fixedly connected to the mounting column 22 through a connecting rod 231 to achieve fixed installation of the first sliding rod 23. The upper frame 30 is slidably connected to the first sliding rod 23 to provide guiding support for the radial sliding of the filter frame and ensure that the filter frame slides stably during the treatment of chemical fiber wastewater.

[0050] Each filter frame is fixedly installed with an elastic element between itself and the sliding support frame. This elastic element allows one end of the filter frame to fit against the outer surface of the mounting column 22. In the initial state, under the action of the elastic element, the filter frame contracts and fits against the outside of the mounting column 22, facilitating the smooth entry of chemical fiber wastewater and chemicals into the filter frame. The elastic element is a spring 36, one end of which is fixedly connected to the sleeve plate 34, and the other end of which is fixedly connected to the mounting ring 24. The elastic force of the spring 36 enables the filter frame to reset and fit, ensuring the stability of the equipment's cyclic operation.

[0051] The filter frame includes an upper frame 30, a lower frame 31, and multiple connecting rod assemblies. The multiple connecting rod assemblies are fixedly installed between the upper frame 30 and the lower frame 31 to connect the upper frame 30 and the lower frame 31 and form a stable frame structure. A filter bag is fixedly installed between the upper frame 30 and the lower frame 31. The filter bag is made of a material suitable for chemical fiber wastewater, which can effectively intercept fiber debris and fine particulate impurities in the wastewater, while preventing chemical auxiliaries from corroding the filter bag, thus achieving preliminary filtration of chemical fiber wastewater.

[0052] A telescopic plate assembly is fixedly installed on the upper frame 30. One end of the telescopic plate assembly is slidably connected to the first slide rod 23, providing further guidance and support for the sliding of the upper frame 30, and can also adapt to the radial expansion and contraction of the filter frame. The telescopic plate assembly includes a sleeve plate 34 and a fixing strip 35. The fixing strip 35 is fixedly installed on the top of the upper frame 30, and a movable plate 351 is fixedly installed on the fixing strip 35. The sleeve plate 34 has a movable groove 341 for the movable plate 351 to slide. The movable plate 351 can slide along the movable groove 341 to realize the expansion and contraction of the telescopic plate assembly. One end of the first slide rod 23 passes through the interior of the sleeve plate 34 and is slidably connected to the sleeve plate 34, ensuring that the sleeve plate 34 can slide stably along the first slide rod 23 to adapt to the expansion and contraction adjustment of the filter frame.

[0053] The connecting rod assembly is set as an elastic telescopic rod 33. The elastic telescopic rod 33 has a certain elastic extension and contraction capacity, which can adapt to the position adjustment of the filter frame. At the same time, during the subsequent discharge of fiber debris and impurities, it can assist in the folding and unfolding of the filter bag, making it easier for the fiber debris attached to the filter bag to fall off and avoid clogging the filter bag.

[0054] Multiple shafts 61 are fixedly installed on the inner surface of the filter barrel 11. A rotating block 60 is rotatably installed on each shaft 61. The rotating block 60 can rotate freely around the shaft 61. The rotating block 60 is located outside the radial movement range of the filter frame along the filter plate 20 to avoid interference between the filter frame and the rotating block 60 when the filter frame slides. A guide surface 601 is provided on one side of the rotating block 60 to guide the cover 32 to make smooth contact and generate displacement. A baffle plate 62 is fixedly installed on the inner surface of the filter barrel 11. The baffle plate 62 fits against the other side of the rotating block 60 to limit the rotation direction of the rotating block 60, ensure the stability of the action when the cover 32 contacts the rotating block 60, and ensure the shaking effect of the filter bag.

[0055] A cover 32 is fixedly installed on the upper frame 30. One end of the cover 32 forms an inlet between the upper frame 30 and the upper frame 30. When one end of the filter frame is attached to the mounting column 22, the inlet is located directly below the bottom outlet of the feed hopper 13, ensuring that the chemical fiber wastewater and chemicals in the feed hopper 13 can smoothly enter the filter bag through the inlet, avoiding wastewater overflow, and preventing fiber debris from falling onto the filter plate 20.

[0056] A partition plate 21 is provided between each two adjacent filter frames. The partition plate 21 is fixedly installed on the filter plate 20 to separate adjacent filter frames, prevent fiber debris and impurities in different filter frames from interfering with each other, and prevent chemical fiber wastewater from flowing randomly on the filter plate 20, ensuring that wastewater can smoothly enter each filter bag and improve filtration efficiency.

[0057] A second sliding rod 25 is fixedly installed at the bottom of the partition plate 21, and a sliding sleeve 311 is fixedly installed on the lower frame 31. One end of the second sliding rod 25 passes through the interior of the sliding sleeve 311 and is slidably connected to the sliding sleeve 311, providing additional guiding support for the radial sliding of the lower frame 31, ensuring the stability of the overall sliding process of the filter frame, avoiding tilting or displacement of the filter frame, and ensuring stable filtration of chemical fiber wastewater.

[0058] A fixing ring 16 is fixedly installed on the outer surface of the processing cylinder 12, and a support ring 15 is fixedly installed on the outer surface of the fixing ring 16. Multiple collection grooves 70 are detachably provided on the support ring 15. The collection grooves 70 are used to collect fiber debris and particulate impurities discharged from the annular interval, which facilitates the subsequent cleaning and recycling of impurities. A guide ring 14 is fixedly installed on the top of the fixing ring 16. The top of the collection groove 70 is attached to the bottom of the guide ring 14. The guide ring 14 is used to guide the impurities discharged from the annular interval into the collection groove 70, so as to prevent fiber debris from falling to the outside of the equipment and causing secondary pollution.

[0059] A U-shaped magnetic block 161 is fixedly installed on the outer surface of the fixing ring 16, and an iron block 701 that matches the U-shaped magnetic block 161 is fixedly installed on the collection tank 70. Through the magnetic attraction between the U-shaped magnetic block 161 and the iron block 701, the collection tank 70 can be detachably installed on the support ring 15. This ensures the stability of the collection tank 70 installation and facilitates the disassembly and cleaning of the collection tank 70, meeting the needs of frequent cleaning of fiber debris in chemical fiber production.

[0060] The working process of this chemical fiber production wastewater treatment equipment is as follows:

[0061] First, the wastewater from the chemical fiber production process to be treated, along with the corresponding treatment agents (suitable for treating chemical auxiliaries and impurities in the wastewater), are fed into the feed hopper 13. In the initial state, the filter frame is attached to the mounting column 22 under the elastic force of the spring 36, and the inlet formed by the cover 32 and the upper frame 30 is located directly below the bottom outlet of the feed hopper 13. Therefore, the wastewater and agents will smoothly enter the filter bags of each filter frame through the inlet. Fiber debris and fine particulate impurities in the wastewater are blocked in the filter bags. The filtered wastewater passes through the through holes on the filter plate 20 and enters the interior of the treatment cylinder 12, where solid impurities in the wastewater are initially removed.

[0062] The motor 51 is started, and its output drives the stirring rod 50 to rotate. As the stirring rod 50 rotates, it simultaneously drives the stirring shaft 52 to rotate, agitating the wastewater in the treatment cylinder 12. This promotes rapid mixing of the chemical fiber wastewater and the treatment agents, accelerates the degradation of chemical auxiliaries and the coagulation of remaining fine impurities, and improves reaction efficiency. Simultaneously, the stirring rod 50 drives the filter plate 20 to rotate rapidly, and the filter frame rotates synchronously with it. Under centrifugal force, the filter frame overcomes the elastic force of the spring 36 and slides along the first slide rod 23 and the second slide rod 25 towards the inner surface of the filter barrel 11 until the filter frame adheres to the inner surface of the filter barrel 11. Under the continuous action of centrifugal force, the water contained in the fiber debris and particulate impurities in the filter bag is thrown out. The thrown-out wastewater passes through the through holes on the filter plate 20 and enters the interior of the treatment cylinder 12, merging with the wastewater inside the treatment cylinder 12 to ensure effective dehydration of impurities and facilitate subsequent recycling.

[0063] After the impurities in the filter bag are spun dry, the motor 51 is turned off, and the filter plate 20 is driven to rotate in the opposite direction. During the rotation of the filter plate 20, the cover 32 on the upper frame 30 will contact the side of the rotating block 60 with the guide surface 601. Due to the obstruction of the baffle plate 62, the rotating block 60 cannot rotate away from the filter frame. Therefore, the cover 32 cannot directly pass over the rotating block 60. After the cover 32 contacts the rotating block 60, it will move downward under the pressure of the reaction force of the rotating block 60. When the cover 32 moves downward, it will drive the upper frame 30 to move downward, causing the elastic telescopic rod 33 to contract and the filter bag to be in a pleated state. After the cover 32 passes over the rotating block 60, under the elastic force of the elastic telescopic rod 33, the upper frame 30 will drive the cover 32 to rise again, and the filter bag will unfold again. As the filter plate 20 continues to rotate in the opposite direction, the cover 32 will come into contact with multiple rotating blocks 60 in sequence, causing the filter bag to repeatedly fold and unfold. This process can shake the filter bag, helping the fiber debris and impurities in the filter bag to fall off smoothly, preventing the fiber debris from sticking tightly to the filter bag due to stickiness or centrifugal force and being unable to be discharged smoothly, thus avoiding clogging of the filter bag.

[0064] Subsequently, the electric telescopic rod 41 is activated, and the movable end of the electric telescopic rod 41 retracts, causing the closed ring 40 to move downward, thus opening the annular gap between the edge of the filter plate 20 and the filter barrel 11. At this time, the fiber debris and impurities that fall out of the filter bag are discharged through the annular gap under their own gravity. The discharged impurities will fall onto the closed ring 40 or the guide ring 14. Under the guidance of the guide ring 14, they will eventually fall into the collection tank 70, completing the collection and aggregation of impurities, which is convenient for the subsequent recycling or harmless treatment of fiber debris.

[0065] When the fiber debris and impurities in the collection tank 70 accumulate to a certain amount, the collection tank 70 can be directly removed from the support ring 15. Since the collection tank 70 is magnetically connected to the U-shaped magnetic block 161 on the fixing ring 16 through the iron block 701, the disassembly process is convenient. After cleaning the impurities in the collection tank 70, the collection tank 70 is then installed back onto the support ring 15 through the cooperation of the iron block 701 and the U-shaped magnetic block 161, and the chemical fiber wastewater treatment work can continue.

[0066] After the impurities are discharged, the electric telescopic rod 41 is closed. The movable end of the electric telescopic rod 41 extends, driving the closed ring 40 to move upward and close the annular interval. At the same time, the motor 51 starts in reverse, driving the filter plate 20 to rotate in the forward direction. Under the elastic force of the spring 36, the filter frame slides along the first slide rod 23 and the second slide rod 25 towards the mounting column 22, resetting to the initial position, and the next round of chemical fiber wastewater treatment can begin.

[0067] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention.
