Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, and specifically relates to a wastewater treatment device for water jet looms. Background Technology

[0002] Water jet looms rely on high-pressure water jets to complete the weft insertion operation, resulting in a large volume of production wastewater. The water mainly contains shed fiber debris, weaving lubricating oil, emulsified white oil, textile sizing agents, and suspended solids. Direct discharge can easily cause water pollution and pipe network blockage.

[0003] Existing wastewater treatment devices for water jet looms generally adopt a structure in which the filtration, stirring, and scraping units are set up separately. On the one hand, the coarse and fine filters are mostly fixed static filter bodies, and the filter holes are easily blocked by debris, requiring frequent shutdowns for manual cleaning, resulting in insufficient continuous operation capacity. On the other hand, the stirring drive and the scraping lifting drive are independent of each other, requiring multiple sets of power equipment and electrical control and sensing components, resulting in high equipment manufacturing costs. Summary of the Invention

[0004] The purpose of this invention is to provide a wastewater treatment device for water jet looms in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A wastewater treatment device for a water-jet loom includes a housing.

The reciprocating mechanism includes a guide rod fixedly mounted within the housing. A slide is slidably mounted on the guide rod. A stirring rod is rotatably mounted on the slide. A linkage mechanism is provided between the stirring rod and the guide rod. A swing mechanism is provided on the slide. The swing mechanism includes a first horizontal shaft and a second horizontal shaft rotatably mounted parallel to each other within the slide. The first horizontal shaft is connected to the stirring rod via the linkage mechanism. A rocker arm assembly is mounted on the second horizontal shaft. A scraper mechanism is slidably mounted on the slide. The scraper mechanism includes a mounting frame. A connecting frame is fixedly mounted on the mounting frame and slidably mounted on the slide. The connecting frame is connected to the rocker arm assembly.

[0006] As a further optimization of the present invention, the reciprocating moving mechanism further includes a reciprocating lead screw rotatably mounted on the housing, a crescent pin rotatably mounted on the slide and connected to the reciprocating lead screw, a guide rod mounted on both sides of the reciprocating lead screw, and a bellows cover between the two sides of the slide and the housing, the bellows cover being fitted onto the guide rod and the reciprocating lead screw.

[0007] As a further optimization of the present invention, movable rods are fixedly provided on both sides of the connecting frame, the movable rods are slidably mounted on the slide, and a rubber plate is fixedly provided on the mounting frame, with an embedding groove provided on the rubber plate.

[0008] As a further optimization of the present invention, a gear two is fixedly arranged on the first horizontal shaft, an incomplete gear is fixedly arranged on the second horizontal shaft, the incomplete gear meshes with the gear two, and a torsion spring is arranged between the second horizontal shaft and the slide.

[0009] As a further optimization of the present invention, the rocker arm assembly includes an arm rod, which is fixedly mounted on a horizontal shaft. A sliding groove is provided on the arm rod, and a crossbar is fixedly mounted on the moving rod. The crossbar is slidably mounted in the sliding groove.

[0010] As a further optimization of the present invention, the linkage mechanism includes a gear, which is fixedly mounted on the stirring rod. A rack is fixedly mounted on the guide rod and meshes with the gear. A bevel gear A and a bevel gear B are respectively mounted on the stirring rod and the horizontal shaft, and the bevel gear A and the bevel gear B mesh with each other.

[0011] As a further optimization of the present invention, the lower end of the box is connected to a conical groove, an overflow chamber is opened in the box on one side of the conical groove, partitions are symmetrically arranged on both sides of the box above the conical groove, the partitions are embedded in the embedding groove, a sludge storage rack is fixedly arranged in the box on the side opposite to the overflow chamber, and a drain pipe connected to the overflow chamber is provided on the box.

[0012] As a further optimization of the present invention, the coarse filtration mechanism includes an auger rotatably mounted on the housing, a filter cylinder fixedly mounted on the housing and sleeved on the auger, one end of the filter cylinder being open and an inlet pipe penetrating the housing being fixedly mounted on the filter cylinder.

[0013] As a further optimization of the present invention, both the auger and the reciprocating screw are provided with synchronous pulleys, and synchronous belts are sleeved on the synchronous pulleys. A servo motor is fixedly installed on the housing, and the output end of the servo motor is connected to the auger.

[0014] As a further optimization of the present invention, the fine filtration mechanism includes an inclined filter plate, a gradient filter plate is provided on one side of the inclined filter plate, the open end of the filter cylinder is located above the gradient filter plate, and an inverted V-shaped guide plate is provided below the inclined filter plate. The guide plate is fixedly arranged between the gradient filter plate and the housing.

[0015] The beneficial effects of this invention are as follows: 1. Unlike existing technologies, in actual use, the coarse filtration mechanism and the fine filtration mechanism arranged from top to bottom in the box form a two-stage filtration system. Wastewater enters the filter cartridge through the inlet pipe to complete the first stage of coarse filtration. The auger simultaneously transports the intercepted large particles and fibers to the gradient filter plate for centralized collection. The filtered water flows through the inclined filter plate to complete the second stage of fine filtration. It can intercept pollutants of different particle sizes step by step. With the help of the inverted V-shaped guide plate, the wastewater is diverted to the two side chambers, which not only improves the filtration anti-clogging ability, but also achieves uniform water distribution.

[0016] 2. Unlike existing technologies, in actual use, during the reciprocating movement of the slide along the guide rod, the linkage mechanism causes the stirring rod to rotate synchronously, achieving full-area walking stirring and mixing, enhancing the mixing effect of the agent and wastewater; simultaneously, the stirring rod, through the horizontal shaft of the swing mechanism, utilizes the intermittent meshing characteristics of gear two and incomplete gears, combined with the elastic reset effect of the torsion spring, to drive the horizontal shaft two to swing back and forth at a certain angle, and then through the rocker arm assembly, drives the moving rod and connecting frame to slide vertically along the slide, so that the scraper mechanism automatically completes the lifting and lowering switching with the direction of travel of the slide. Thus, when the slide moves towards the sludge storage rack, the mounting frame drives the rubber plate to descend, and the rubber plate engages with the partition through the embedded groove, simultaneously scraping off the floating oil and flocculated scum on both sides of the liquid surface and pushing it into the sludge storage rack for collection; when the slide reverses and resets, the mounting frame automatically raises to detach the rubber plate from the liquid surface, preventing scum from being carried back.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1, as Figure 1 - Figure 10 As shown, a wastewater treatment device for a water jet loom includes a box 1 with a vertical cavity structure. Inside the box 1, a coarse filter mechanism 3, a fine filter mechanism 4, and a reciprocating moving mechanism 5 are arranged sequentially from top to bottom. The reciprocating moving mechanism 5 is equipped with a stirring rod 7, a linkage mechanism 9, a swing mechanism 10, and a scraper mechanism 6.

[0021] like Figure 3 As shown, the coarse filtration mechanism 3 is horizontally arranged in the upper part of the housing 1, including an auger 31 and a filter cartridge 32. The filter cartridge 32 is a cylindrical filter screen structure and is fixedly mounted on the inner wall of the housing 1. The auger 31 is coaxially rotated and passes through the inside of the filter cartridge 32. The top of the side wall of the filter cartridge 32 is connected to an inlet pipe 33 that penetrates the side wall of the housing 1. One end of the filter cartridge 32 is open and the other end is closed. Wastewater is sent into the interior of the filter cartridge 32 through the inlet pipe 33. The water flows downward through the mesh of the filter cartridge 32. Impurities such as polyester long fibers and large particle slurry agglomerates are trapped on the inner wall of the filter cartridge 32 and continuously transported to the open end by the spiral blades of the auger 31.

[0022] like Figure 3 - Figure 4As shown, the fine filtration mechanism 4 is located directly below the coarse filtration mechanism 3, and includes an inclined filter plate 41, a gradient filter plate 42, and a guide plate 43. The inclined filter plate 41 is fixedly mounted on the inner wall of the housing 1, and its filter hole diameter is smaller than that of the filter cylinder 32, for completing the secondary fine filtration. The gradient filter plate 42 is fixedly installed on the lower side of the inclined filter plate 41 and located directly below the opening end of the filter cylinder 32, for receiving the filter residue discharged from the coarse filtration mechanism 3 and the fine fiber debris sliding down from the inclined filter plate 41. A collection port is provided on the side wall of the housing 1 corresponding to the position of the gradient filter plate 42, which facilitates the periodic cleaning of the collected debris. The guide plate 43 has an inverted V-shaped structure. The guide plate 43 is fixedly mounted below the inclined filter plate 41 and located between the gradient filter plate 42 and the inner wall of the housing 1. The wastewater filtered by the inclined filter plate 41 falls onto the guide plate 43 and is diverted to both sides along the inverted V-shaped slope, entering the chambers on both sides of the housing 1.

[0023] like Figure 3 and Figure 10 As shown, two vertical partitions 11 are symmetrically fixed in the lower part of the box 1. The two partitions 11 and the two side walls of the box 1 form a two-sided diversion cavity. The middle treatment cavity is between the two partitions 11. A drug inlet pipe is connected to the middle treatment cavity. After the wastewater is diverted by the guide plate 43, it enters the two-sided diversion cavity. The less dense floating oil floats to the liquid surface, while the water flows into the middle treatment cavity from the gap at the lower end of the partition 11. The bottom of the tank 1 is provided with a conical groove 15 that tapers downwards to collect settled sludge. A drain valve is provided on the conical groove 15. An overflow chamber 12 is provided on one side inside the tank 1. The overflow chamber 12 is connected to the central treatment chamber through an overflow weir. A drain pipe 14 connected to the bottom of the overflow chamber 12 is fixed on the outer wall of the tank 1. A sludge storage rack 13 is fixed on the other side of the tank 1 opposite to the overflow chamber 12 to receive floating oil and scum pushed by the scraper mechanism 6. A drain channel connected to the sludge storage rack 13 is provided on the tank 1.

[0024] like Figure 3 and Figure 5 - Figure 6 As shown, the reciprocating moving mechanism 5 is located in the upper liquid surface area of ​​the central processing chamber, including a reciprocating lead screw 52, ​​a guide rod 53, and a slide 51. The reciprocating lead screw 52 and the guide rod 53 are both horizontally arranged and parallel to each other. The reciprocating lead screw 52 is rotatably mounted on the inner wall of the housing 1, and the guide rod 53 is fixedly mounted on the inner wall of the housing 1. The slide 51 is connected to the reciprocating lead screw 52 through a crescent pin 511. At the same time, the slide 51 is slidably sleeved on the guide rod 53. When the reciprocating lead screw 52 rotates, the slide 51 is driven to make a horizontal reciprocating linear motion along the guide rod 53 through the transmission cooperation of the crescent pin 511. A bellows cover 8 is provided between the two sides of the slide 51 and the housing 1. The bellows cover 8 is sleeved on the guide rod 53 and the reciprocating lead screw 52.

[0025] like Figure 2 - Figure 3As shown, a servo motor 2 is fixedly installed on the outer wall of the housing 1. The output shaft of the servo motor 2 is coaxially and fixedly connected to the auger 31 of the coarse filter mechanism 3. Synchronous pulleys 211 are fixedly fitted on the shaft end of the auger 31 and the shaft end of the reciprocating screw 52 of the reciprocating moving mechanism 5. A synchronous belt 21 is tensioned between the two sets of synchronous pulleys 211. When the servo motor 2 starts, it drives the auger 31 and the reciprocating screw 52 to rotate synchronously through the transmission of the synchronous pulleys 211 and the synchronous belt 21, thereby realizing the power splitting of a single power source.

[0026] like Figure 6 - Figure 7 As shown, a stirring rod 7 is vertically rotatably mounted on the slide 51, with its lower blades extending into the water. A linkage mechanism 9 is located between the stirring rod 7 and the guide rod 53, including a gear 91, a rack 93, a bevel gear A92, and a bevel gear B921. Gear 91 is fixedly mounted on the upper part of the stirring rod 7, and the rack 93 is fixedly mounted on the guide rod 53 along its length, with the rack 93 meshing with gear 91. When the slide 51 moves along the guide rod 53, gear 91 rolls along the rack 93, thereby causing the stirring rod 7 to rotate synchronously, thus performing a moving stirring and mixing of the wastewater and chemicals in the central treatment chamber. Bevel gear A92 is fixedly mounted on the top of the stirring rod 7, and bevel gear B921 is fixedly mounted on the end of the swing mechanism 10. Bevel gear A92 and bevel gear B921 mesh vertically, reversing the rotational power of the stirring rod 7 and transmitting it to the swing mechanism 10.

[0027] like Figure 6 and Figure 8 As shown, the swing mechanism 10 is installed inside the slide 51, including a first horizontal shaft 101, a second horizontal shaft 102, a torsion spring 103, and a rocker arm assembly 104. The first horizontal shaft 101 and the second horizontal shaft 102 are parallel to each other and are both horizontally rotatably installed inside the slide 51. A bevel gear B921 is fixed to one end of the first horizontal shaft 101. A second gear 1011 is fixedly mounted on the rod of the first horizontal shaft 101, and an incomplete gear 1021 is fixedly mounted on the rod of the second horizontal shaft 102. The toothed section of the incomplete gear 1021 meshes with the second gear 1011, and the toothless section disengages from the second gear 1011. The torsion spring 103 is sleeved on the second horizontal shaft 102, and the two ends of the torsion spring 103 are respectively connected to the second horizontal shaft 102 and the slide 51, providing a restoring force for the second horizontal shaft 102. When the horizontal shaft 101 rotates continuously, the gear 1011 meshes with the toothed section of the incomplete gear 1021, driving the horizontal shaft 102 to rotate and compressing the torsion spring 103. When the gear 1011 rotates to face the toothless section of the incomplete gear 1021, the two disengage, and the torsion spring 103 releases its elastic force to keep the horizontal shaft 102 in a return-to-normal state, and keeps the tooth tip of the incomplete gear 1021 against the tooth surface of the gear 1011, ensuring that the next round of meshing is accurately engaged. Thus, the horizontal shaft 102 forms a reciprocating oscillation at a certain angle.

[0028] like Figure 8 - Figure 9 As shown, the rocker arm assembly 104 is connected between the second horizontal shaft 102 and the scraper mechanism 6, and includes an arm 1041 and a crossbar 1043; one end of the arm 1041 is fixedly fitted onto the second horizontal shaft 102, and a groove 1042 extending along the length direction is provided on the arm body of the arm 1041; the scraper mechanism 6 includes a mounting frame 61, a rubber plate 62, a connecting frame 63 and a moving rod 631, the connecting frame 63 is symmetrically fixed on both sides of the top of the mounting frame 61, and the top of each of the two connecting frames 63 is fixed with a moving rod 631, which slides vertically through the slide frame 51; the crossbar 1043 is fixedly connected between the two moving rods 631, and the crossbar 1043 is slidably embedded in the groove 1042. When the horizontal axis 102 reciprocates, the arm 1041 swings synchronously. Through the cooperation of the slide groove 1042 and the crossbar 1043, the moving rod 631 is pulled up and down along the slide frame 51, and then the mounting frame 61 is driven by the connecting frame 63 to achieve the lifting action. A rubber plate 62 is fixedly installed at the bottom of the mounting frame 61. The bottom of the rubber plate 62 has an embedding groove 621 corresponding to the position of the partition 11. When the mounting frame 61 is lowered to the working position, the upper end of the partition 11 is embedded in the embedding groove 621, and the rubber plate 62 is in contact with the liquid surface. As the slide frame 51 moves, it synchronously scrapes away the floating oil and flocculated scum on the liquid surface of the two side diversion chambers and the middle treatment chamber.

[0029] It should be noted that the working process of this water jet loom wastewater treatment device is as follows: Wastewater from the water jet loom is fed into the filter cylinder 32 through the inlet pipe 33. The servo motor 2 drives the auger 31 to rotate. After the wastewater passes through the filter cylinder 32 and completes the first-stage coarse filtration, it falls down. The large fiber particles and impurities that are trapped are transported by the auger 31 to the open end of the filter cylinder 32 and fall onto the gradient filter plate 42 for collection. The coarsely filtered wastewater falls to the inclined filter plate 41 to complete the second-stage fine filtration. The fine fibers intercepted by the inclined filter plate 41 slide along the plate surface and flow into the gradient filter plate 42. It can be cleaned periodically through the collection port on the side wall of the box 1. The finely filtered wastewater is diverted to the diversion chambers on both sides of the box 1 through the inverted V-shaped guide plate 43. The floating oil rises to the liquid surface, and the water enters the middle treatment chamber from the lower end of the partition plate 11.

[0030] The servo motor 2 drives the reciprocating screw 52 to rotate synchronously through the synchronous pulley 211 and the synchronous belt 21, which drives the slide 51 to move back and forth along the guide rod 53. When the slide 51 moves, the gear 91 rolls along the rack 93, driving the stirring rod 7 to rotate, which fully mixes the reagents and wastewater added in the middle treatment chamber, so that the light flocs formed by the colloids and suspended solids in the wastewater float to the surface, while the remaining flocs settle to the bottom. At the same time, the stirring rod 7 drives the horizontal shaft 101 to rotate through the bevel gears A92 and B921. Through the intermittent meshing of the gear 1011 and the incomplete gear 1021, and the reset action of the torsion spring 103, the horizontal shaft 102 swings back and forth at a certain angle. Then, through the rocker arm assembly 104, the scraper mechanism 6 automatically rises and falls with the direction of travel of the slide 51.

[0031] When the slide 51 moves toward the sludge storage rack 13, it is driven by the meshing of the incomplete gear 1021 and the gear 1011. The horizontal shaft 102 swings and drives the mounting frame 61 to descend. When the gear 1011 rotates to face the toothless section of the incomplete gear 1021, the two disengage. The torsion spring 103 releases its elastic force and drives the horizontal shaft 102 to maintain its reset tendency, thereby stopping the rotation of the incomplete gear 1021. The tooth end of the incomplete gear 1021 always abuts against the tooth surface of the gear 1011. The rubber plate 62 adheres to the liquid surface and engages the partition 11 through the embedded groove 621, simultaneously scraping and pushing the floating oil and flocculated scum on the liquid surface into the sludge storage rack 13 for collection and discharge through the sewage discharge channel. When the slide 51 moves in the reverse reset direction, the incomplete gear 1021 is driven in the reverse direction through the gear 1011. The mounting frame 61 is raised to make the rubber plate 62 leave the liquid surface, preventing the scum from being carried back. The treated clarified water overflows into the overflow chamber 12 and is eventually discharged through the drain pipe 14; the settled sludge collects in the bottom cone trough 15 and can be discharged in a concentrated manner by opening the sludge discharge valve periodically.

[0032] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
