Description

Technical Field

[0001] This utility model relates to the field of wastewater recycling technology, and in particular to a wastewater recycling and repeated filtration device for water jet looms. Background Technology

[0002] Water jet looms are a type of loom that uses water jets to guide the weft. They use a large amount of water, and the water jets wash away the fibers on the yarn. The water after jetting is collected and enters a wastewater tank. In order to save water resources, the wastewater in the wastewater tank is currently recycled. During the recycling process, flotation machines are mostly used to treat foreign objects and fibers in the wastewater with chemicals. The resulting floating matter is scraped off by scrapers.

[0003] However, simply using an air flotation machine for filtration not only increases the workload of the machine but also makes it difficult to clean up floating debris, which tends to adhere to the inside of the tank and the nozzles. This is because the wastewater is directly introduced into the air flotation machine after collection, undergoing only simple flocculant treatment with added chemicals. This significantly reduces the lifespan of the air flotation machine and increases the labor required for manual maintenance. Therefore, there is an urgent need for a wastewater recycling and repeated filtration device for water jet looms before introducing wastewater into the air flotation machine, which can treat and filter out the flocculent matter in the wastewater through multiple filtrations. Utility Model Content

[0004] The technical problem this invention aims to solve is that directly introducing wastewater into the flotation machine for treatment will affect the service life of the flotation machine, and a large amount of flocculent material is difficult to clean, resulting in insufficiently clear discharged filtered water, which in turn affects the subsequent chemical treatment.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a wastewater recycling and repeated filtration device for water jet looms, including a recycling and treatment tank, a filtration device is provided at the water inlet end of the recycling and treatment tank, and a connecting water inlet pipe is fixedly connected to the outer end of the filtration device. The filtration device includes: a filter box, a water storage chamber is provided inside the filter box near the water inlet pipe, a transition chamber is provided beside the water storage chamber, and a filtration mechanism is provided at the upper inlet of the transition chamber. The filtration mechanism can repeatedly filter wastewater. The filter box includes a filter plate. The filter plate is inclined, and a return trough is fixedly connected to the lower inclined end of the filter plate. A return pipe is fixedly connected to both ends of the return trough, and the other end of the return pipe extends to the wastewater and is located above the highest liquid level of the wastewater. A multi-stage interception mechanism is located inside the filter box. This mechanism further intercepts flocculent matter in the wastewater, reducing the transmission of flocculent matter within the wastewater. A connecting cavity is provided on one side of the multi-stage interception mechanism, and a connecting pipe is connected to it, which is connected to a recycling and treatment box.

[0006] Furthermore, the multi-stage barrier mechanism includes: a grading plate, which is located in the middle of the filter box and is folded; one side of the grading plate is a flow chamber and the other side is a sedimentation chamber; and a grading mesh, which is located at the upper end of the grading plate. A slot is fixedly connected to the upper end of the grading plate, and a first barrier mesh and a second barrier mesh are inserted into the slot. The first barrier mesh is located on both sides of the second barrier mesh, and the mesh sizes of the first barrier mesh and the second barrier mesh are different.

[0007] Furthermore: a drive motor is fixedly connected to the lower end of the filter box, the output end of the drive motor is located in the transition cavity, and a stirring blade is fixed to the output end of the drive motor, which can drive the wastewater to rise and tumble.

[0008] Furthermore, the filter box is provided with a cover plate at its upper end, and the cover plate is respectively located at the upper end of the transition chamber and the grading plate.

[0009] Furthermore, the return pipe is inclined, and one end of it is located higher than the end located at the wastewater.

[0010] Furthermore, the mesh positions of the first and second barrier nets are staggered.

[0011] The beneficial effects of this utility model are:

[0012] (1) The wastewater recycling and repeated filtration device of the present invention: by setting up a filtration device, the flocculent matter in the wastewater can be filtered, and at the same time, the wastewater can be returned for filtration again. Meanwhile, before the wastewater enters the recycling tank, it needs to pass through a multi-stage barrier mechanism to block the flocculent matter and foreign matter, which greatly reduces the flocculent matter and foreign matter in the wastewater entering the recycling tank.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1-5As shown: This utility model provides a technical solution for a wastewater recycling and repeated filtration device for water jet looms, including a recycling and treatment tank 1. A filtration device is installed at the water inlet end of the recycling and treatment tank 1, and a connecting water inlet pipe 3 is fixedly connected to the outer end of the filtration device. The filtration device includes a filter box 2, a water storage chamber 6 is provided inside the filter box 2 near the water inlet pipe 3, a transition chamber 7 is provided beside the water storage chamber 6, and a filtration mechanism is provided at the upper inlet of the transition chamber 7. The filtration mechanism can repeatedly filter wastewater. The filter box 2 includes a filter plate 8, which is inclined and the lower inclined end of the filter plate 8 is fixedly connected to the filter plate 8. A return trough 9 is fixedly connected to both ends of the return trough 9, and a return pipe 10 is fixedly connected to both ends of the return trough 9. The other end of the return pipe 10 extends to the wastewater and is located above the highest liquid level of the wastewater. A multi-stage interception mechanism is set inside the filter box 2. The multi-stage interception mechanism reduces the transmission of flocculent matter in the wastewater by further intercepting it. A connecting cavity 19 is set on one side of the multi-stage interception mechanism, and a connecting pipe 4 is connected to the recycling and treatment box 1. After the water jet loom discharges wastewater, it is collected in the wastewater tank and then processed by water jet loom. The pump drives the inlet pipe 3 to draw wastewater into the filter box 2. Upon entering the filter box 2, the wastewater first flows into the storage chamber 6. After being stored in the storage chamber 6, the wastewater flows from the upper end of the storage chamber 6 into the transition chamber 7. Then, the wastewater flows along the filter plate 8, which filters out larger foreign objects and flocculent matter. Excess water is divided into two parts: most flows from the filter plate 8 into the transition chamber 7, while a smaller portion flows through the filter plate 8 into the return trough 9. The water then flows through the return pipe 10 back to the wastewater tank for further circulation and filtration. This allows the wastewater that was not filtered on the filter plate 8 to be filtered again, greatly reducing the flocculent matter in the wastewater. Then, the wastewater flows from the transition chamber 7 to the next stage of the multi-stage barrier mechanism. The multi-stage barrier mechanism can further block various flocculent matter in the wastewater. Then, the wastewater flows into the connecting chamber 19. The connecting chamber 19 discharges the water into the recycling and treatment tank 1 for centralized treatment through the connecting pipe 4. This greatly reduces the workload of the recycling and treatment tank 1 and improves the working efficiency of the recycling and treatment tank 1, thereby making the final wastewater clearer and easier for the next chemical treatment.

[0023] like Figure 4 and Figure 5As shown: The multi-stage barrier mechanism includes: a grading plate 14, which is located in the middle of the filter box 2 and is folded; one side of the grading plate 14 is a flow chamber 13, and the other side is a sedimentation chamber 18; a grading mesh, which is located at the upper end of the grading plate 14, and a slot 15 is fixedly connected to the upper end of the grading plate 14. A first barrier mesh 16 and a second barrier mesh 17 are inserted into the slot 15. The first barrier mesh 16 is located on both sides of the second barrier mesh 17, and the mesh sizes of the first barrier mesh 16 and the second barrier mesh 17 are different. The grading plate 14 divides the interior of the filter box 2 into two chambers, one of which, located on the left side of the grading plate 14, is the flow chamber 13, and the other side is the sedimentation chamber 18. To the right of the classifying plate 14 is the sedimentation chamber 18. In the flow chamber 13, wastewater flows from the upper end of the classifying plate 14 to the sedimentation chamber 18. When the wastewater passes through the folded upper end of the classifying plate 14, it passes through the first barrier net 16 and the second barrier net 17. The multiple layers of barriers between the first barrier net 16 and the second barrier net 17 can further improve the filtration efficiency. Moreover, the first barrier net 16 and the second barrier net 17 are detachable, which is convenient for later maintenance and replacement. Furthermore, the mesh size between the first barrier net 16 and the second barrier net 17 is different, which can intercept flocculent matter and foreign objects of different sizes. At the same time, the wastewater settles in the sedimentation chamber 18, and the cleaner water flows from the upper end of the sedimentation chamber 18 into the connecting chamber 19.

[0024] like Figure 4 As shown: A drive motor 11 is fixedly connected to the lower end of the filter box 2. The output end of the drive motor 11 is located in the transition chamber 7. A stirring blade 12 is fixed to the output end of the drive motor 11. The stirring blade 12 can drive the wastewater to rise and tumble. The drive motor 11 fixed at the lower end of the filter box 2 can drive the stirring blade 12 inside the transition chamber 7 to rotate. When the stirring blade 12 rotates, it can drive the wastewater inside the transition chamber 7 to tumble up and down through the stirring of the blade. This can disperse the flocculent matter and foreign matter in the wastewater, thus facilitating the next step of filtration.

[0025] like Figure 2 As shown: The upper end of the filter box 2 is provided with a cover plate 5. The cover plate 5 is located at the upper end of the transition chamber 7 and the upper end of the grading plate 14. The cover plate 5 can reduce the odor in the wastewater and prevent foreign objects from falling into the interior. At the same time, after opening the cover plate 5, the filter plate 8, the first barrier net 16 and the second barrier net 17 can be cleaned and replaced.

[0026] like Figure 2 As shown: the return pipe 10 is set at an angle, and one end of the return tank 9 is set higher than the end located at the wastewater. The angled return pipe 10 can return wastewater without electric drive, saving electricity and operating costs.

[0027] like Figure 5 As shown: the mesh positions of the first barrier net 16 and the second barrier net 17 are staggered; the staggered mesh position can prevent foreign objects and lint from passing through directly, and the staggered position keeps the lint and foreign objects between the first barrier net 16 and the second barrier net 17.

[0028] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
