Description

Technical Field

[0001] This invention belongs to the technical field of water treatment equipment, and in particular relates to a water circulation purification device for a water jet loom. Background Technology

[0002] Water jet looms are a new type of shuttleless loom that uses a jet of water to guide the weft yarn through the shed. They are a technologically mature and automated piece of equipment in textile machinery, widely used in the weaving of synthetic fiber filaments and blended fabrics. Their core principle involves a high-pressure water pump generating a high-speed water jet that draws the weft yarn from the weft feeder into the nozzle. After being accelerated through a water channel, the water jet forms a continuous jet that propels the weft yarn through the warp opening, completing the weft insertion. Water jet looms rely on high-pressure water to propel the weft yarn through the shed, meaning that a large amount of clean water is consumed for every meter of fabric woven. Direct discharge not only incurs high water costs but, more critically, the wastewater contains large amounts of sizing agents (PVA, starch) and lubricating oil, resulting in extremely high COD (chemical oxygen demand) levels, which severely damage the environment.

[0003] A Chinese patent application (or patent) with publication number CN215161476U discloses a water circulation purification system for a water jet loom, including a clean water tank. A water storage tank is fixedly connected to the bottom of the clean water tank. A tank cover is provided at the top of the clean water tank. An internal thread is provided on the inner wall of the top of the clean water tank. A threaded sleeve is fixedly connected to the bottom surface of the tank cover. The outer side of the threaded sleeve is threadedly connected to the inner wall of the top of the clean water tank. A filter screen is provided at the bottom of the tank cover. An annular plate is fixedly connected to the outer top of the filter screen.

[0004] However, the above-mentioned device still has the following problems during implementation: In the process of treating wastewater from water jet looms, filter screens are used to intercept suspended impurities in the water. However, because the wastewater is rich in sizing agents, oils, and other components, it is easy to form highly viscous flocs. If conventional filter screens are used directly, these flocs will quickly adhere to and entangle on the surface of the filter screen, causing the mesh to become clogged and the flow area to be drastically reduced. In severe cases, it may even cause the machine to be shut down for cleaning, which not only disrupts the continuity of wastewater circulation but also significantly increases the cost of manual maintenance.

[0005] To address this issue, we provide a water circulation purification device for water jet looms. Summary of the Invention

[0006] The purpose of this invention is to provide a water circulation purification device for water jet looms. Through the structural coordination of water treatment components, filtration components, and aeration components, it solves the problem in the prior art that water circulation purification systems for water jet looms use filter screens to filter impurities in the water, but the wastewater contains a lot of flocculents, and direct filtration through the filter screen will clog the filter screen and affect the wastewater circulation effect.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0008] This invention relates to a water circulation and purification device for a water-jet loom, comprising a filter housing, inside which a filter plate and a flow divider are installed.

[0015] The invention is further configured such that a guide rail plate is fixedly connected to the top of the vertical plate, a guide groove is provided at the bottom of the support plate, and a mounting bolt is provided through the bottom of the guide groove.

[0016] The present invention is further configured such that a water guide plate is slidably connected to one side of the vertical plate, and the bottom of the water guide plate is fixedly connected to the inner wall of the purification shell.

[0017] The present invention is further configured such that a support frame is fixedly connected to the surface of the purification shell, and a controller is installed inside the support frame.

[0018] The present invention has the following beneficial effects: By setting up a filter plate and a diversion plate, the present invention achieves the initial interception and stratified sedimentation of large particulate matter and suspended solids, effectively reducing the burden of subsequent treatment. By setting up a dual-axis motor to synchronously drive the mixing blades, sealing plate and sealing plug, the present invention achieves the linkage of quantitative addition of flocculant and aeration mixing of wastewater, which significantly improves the flocculation reaction efficiency and the uniformity of drug solution mixing.

[0031] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1

[0032] Please see Figures 1-9This invention relates to a water circulation purification device for a water-jet loom, comprising a filter housing 1, a filter plate 2 and a diverter plate 3 installed inside the filter housing 1, a drain pipe 4 connected to one side of the filter housing 1, and a purification housing 5 connected to the other end of the drain pipe 4; a water treatment component 6 is installed inside the purification housing 5, the water treatment component 6 including a dual-axis motor 601 installed inside the purification housing 5, a drive shaft 602 installed at the output end of one side of the dual-axis motor 601, mixing blades 603 installed on the surface of the drive shaft 602, a liquid storage tank 604 located on one side of the filter housing 1, a liquid injection tank 605 opened inside the purification housing 5, a sealing plate 606 slidably connected inside the liquid injection tank 605, and an inlet pipe 607 and an outlet pipe 608 connected to one side of the liquid injection tank 605, through which water is processed. The purification assembly 6 performs flocculation treatment on the wastewater; the purification shell 5 is equipped with a filtration assembly 7, which includes a hydraulic rod 701 located at the top of the purification shell 5, a support plate 702 installed at the output end of the hydraulic rod 701, a vertical plate 703 located at the bottom of the support plate 702, and a filter screen 704 connected to one side of the vertical plate 703. The filtration assembly 7 filters the flocculated material; the purification shell 5 is equipped with an aeration assembly 8, which includes an exhaust trough 801 opened inside the purification shell 5, a sealing plug 802 slidably connected inside the exhaust trough 801, an air inlet pipe 803 and an exhaust pipe 804 connected to one side of the exhaust trough 801, and a nozzle 805 connected to the other end of the exhaust pipe 804. The aeration assembly 8 accelerates the efficiency of flocculation treatment.

[0033] Specifically: Filter shell 1 is used for natural sedimentation and preliminary separation of impurities; filter plate 2 is used to intercept larger solid debris such as broken wires and fibers mixed in the wastewater; diversion plate 3 is used to guide and separate the water flow, causing floating dirt and heavier impurities in the water to settle or float respectively; drain pipe 4 is used to smoothly transport the pre-treated wastewater from filter shell 1 to purification shell 5; dual-shaft motor 601 is used to simultaneously drive the output ends on both sides for mechanical movement; mixing blades 603 are used to rotate at high speed in the wastewater, generating strong eddies and shear forces, allowing the flocculant to fully contact and react quickly with suspended particles; storage tank 604 is used to store liquid flocculant for easy replenishment; injection tank 605 is used to stably transport the agent; sealing plate 606 is used to reciprocate within injection tank 605, changing the volume of the tank. The system enables the intake and expulsion of flocculants, precisely controlling the dosage of each injection. The inlet pipe 607 introduces the flocculant from the storage tank 604 into the injection tank 605, and the outlet pipe 608 delivers a fixed amount of flocculant to the wastewater in the purification shell 5.

The filter screen 704 intercepts flocculants under the action of water vortex, achieving efficient solid-liquid separation. The exhaust tank 801 stores fresh air from the outside and forms a directional airflow under the push of the sealing plug 802. The sealing plug 802 reciprocates within the exhaust tank 801, changing the volume of the tank to achieve the intake and expulsion of gas, forming a stable air supply. Example 2

The other side of the push rod 809 is fixedly connected to the sealing plug 802, and the other side of the movable rod 8010 is fixedly connected to the sealing plate 606.

[0035] Specifically: the intake pipe 803 is used to introduce external air into the exhaust trough 801; the exhaust pipe 804 is used to deliver compressed air to the nozzle 805; the nozzle 805 is used to release high-pressure air into the wastewater in the form of microbubbles to accelerate the flocculation reaction process; the rotating plate 806 is used to rotate synchronously with the motor output shaft; the rotating shaft 807 is used to form an eccentric transmission structure to drive the moving frame 808 to produce reciprocating linear motion; the moving frame 808 is used to convert the circular motion of the rotating shaft 807 into its own horizontal reciprocating motion; and the push rod 809 is used to push the moving frame 808... The reciprocating motion is transmitted to the sealing plug 802. The moving rod 8010 is used to transmit the reciprocating motion of the moving frame 808 to the sealing plate 606. The first one-way valve 9 is used to allow the flocculant to flow only from the storage tank 604 to the injection tank 605 to prevent backflow. The second one-way valve 10 is used to allow the flocculant to flow only from the injection tank 605 to the inside of the purification shell 5 to prevent backflow. The third one-way valve 11 is used to allow external air to enter only the exhaust tank 801 to prevent compressed gas leakage. The fourth one-way valve 12 is used to allow the compressed air in the exhaust tank 801 to flow only to the nozzle 805 to prevent backflow. Example 3

[0036] Please see Figures 1-9 Based on Embodiments 1 and 2, a bracket 13 is mounted on the surface of the hydraulic rod 701. The bottom of the bracket 13 is fixedly connected to the purification shell 5. A water outlet pipe 14 is connected to one side of the purification shell 5, and a water pump 15 is connected to the other end of the water outlet pipe 14. The water outlet on the other side of the water pump 15 is connected to the water inlet of the water jet loom through a pipe. A guide rail plate 16 is fixedly connected to the top of the vertical plate 703. A guide groove 17 is opened at the bottom of the support plate 702. An installation bolt 18 is installed through the bottom of the guide groove 17. A water guide plate 19 is slidably connected to one side of the vertical plate 703. The bottom of the water guide plate 19 is fixedly connected to the inner wall of the purification shell 5. A support frame 20 is fixedly connected to the surface of the purification shell 5. A controller 21 is installed inside the support frame 20.

[0037] Specifically: bracket 13 provides rigid support for hydraulic rod 701 and fixes it to the top of purification shell 5; water outlet pipe 14 leads treated clean water out of purification shell 5; water pump 15 provides negative pressure suction to extract purified water and reuse it in the weft insertion system of water jet loom; guide rail plate 16 cooperates with guide groove 17 to connect vertical plate 703 and support plate 702; guide groove 17 provides space for guide rail plate 16 to insert and slide, allowing vertical plate 703 to be horizontally adjusted along the direction of guide groove 17; mounting bolt 18 locks guide rail plate 16 to achieve detachable fixed connection between vertical plate 703 and support plate 702; water guide plate 19 provides vertical guidance for vertical plate 703 and guides filtered clean water to the outlet pipe 14; support frame 20 provides an independent installation position for controller 21, keeping it away from damp and vibration areas; controller 21 sets the operating sequence and intermittent cycle of each actuator to achieve automatic adjustment.

[0038] The working principle of this invention is as follows: the worker transports the wastewater discharged from the water jet loom into the filter shell 1. The filter plate 2 inside the filter shell 1 filters the broken threads in the wastewater. When the water flows into the filter shell 1, the diverter plate 3 separates the floating dirt in the water flow. As the water flow continues to be transported, the heavier impurities settle to the bottom of the filter shell 1, thus achieving preliminary filtration.

[0039] After preliminary filtration, the wastewater enters the purification shell 5 through the drain pipe 4. Then, the dual-shaft motor 601 is started. The dual-shaft motor 601, together with the drive shaft 602, drives the mixing blades 603 to rotate, agitating the wastewater. The dual-shaft motor 601 synchronously drives the rotating plate 806 to rotate, which in turn drives the rotating shaft 807 to rotate. The rotating shaft 807 pushes the moving frame 808 to move, and the moving frame 808, together with the moving rod 8010, drives the sealing plate 606 to move. The sealing plate 606 pushes the air inside the exhaust trough 801 to flow, injecting the gas into the nozzle 805 through the exhaust pipe 804 and the fourth one-way valve 12. The gas is then injected into the wastewater through the nozzle 805, generating bubbles and further improving the mixing effect of the wastewater.

[0040] As the moving frame 808 moves, it drives the push rod 809 to move. The push rod 809 pushes the sealing plug 802 to move. When the sealing plug 802 moves, it drives the liquid inside the injection tank 605 to flow. The flocculant is injected into the purification shell 5 through the liquid outlet pipe 608 and fully mixed with the wastewater to treat the wastewater through flocculation reaction.

[0041] After the wastewater flocculation reaction reaches the specified time, the hydraulic rod 701 is activated. The hydraulic rod 701 pushes the support plate 702 and the vertical plate 703 to move. The vertical plate 703 drives the filter screen 704 to be inserted into the purification shell 5. When the mixing blade 603 rotates, it can agitate the water flow into a vortex. As the water flow rotates continuously, it can enter the filter screen 704. The filter screen 704 actively filters the flocculants in the wastewater, improving water treatment efficiency. The filtered water is pumped out by the water pump 15 and connected to the water inlet of the water jet loom to achieve the function of circulating water supply.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
