Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a wastewater treatment device for polyamide fiber production. Background Technology

[0002] In modern industrial production, polyamide fibers are widely used in textiles, automobiles, electronics, and other fields due to their excellent properties. However, the production process of polyamide fibers generates a large amount of wastewater. This wastewater has a complex composition, containing not only a large amount of chemical agents but also large impurities such as fiber filaments and suspended solids.

[0003] Currently, commonly used filtration devices in the treatment of wastewater from polyamide fiber production have some significant drawbacks. The most prominent problem is that large fibers and suspended solids in the wastewater easily come into direct contact with the filter screen, leading to frequent clogging. Once the filter screen is clogged, it not only reduces filtration efficiency and increases equipment maintenance costs, but may also affect the continuity of the entire wastewater treatment process, causing production interruptions.

[0004] Furthermore, filter components in traditional filtration devices designed to intercept large impurities are difficult to replace once clogged. This cumbersome replacement process not only consumes significant manpower and time but also severely impacts the normal operation of the equipment, reducing production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater treatment device for polyamide fiber production. The device uses a second arc-shaped filter cover to perform preliminary filtration of the wastewater, reducing filter screen clogging. When the second arc-shaped filter cover needs to be replaced, the second arc-shaped filter cover is rotated by rotating the adjustment group, so that one of the second arc-shaped filter covers is connected to the lower side of the first arc-shaped filter cover, thereby achieving rapid replacement of the second arc-shaped filter cover, reducing the difficulty of replacing the second arc-shaped filter cover, and ensuring the continuity of the wastewater treatment operation.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A wastewater treatment device for polyamide fiber production includes a housing with a hollow structure. An inlet pipe is fixedly connected to the upper side of the housing, extending into the interior of the housing. A first arc-shaped filter cover is fixedly connected inside the housing and communicates with the inlet pipe. A rotary adjustment assembly is installed inside the housing, with U-shaped supports fixedly connected to both sides of the rotary adjustment assembly. A second arc-shaped filter cover is rotatably connected within the two U-shaped supports. Multiple circular holes are formed on the two second arc-shaped filter covers, one of which communicates with the first arc-shaped filter cover. A filter screen is fixedly connected inside the housing. Rotary shafts are fixedly connected to both sides of the second arc-shaped filter covers. Rotary holes are formed on both sides of the U-shaped supports, and the rotating shafts are rotatably connected to the holes. An outlet pipe is fixedly connected to one side of the housing, extending into the interior of the housing.

[0008] Furthermore, a magnet is fixedly connected to the lower side of the first arc-shaped filter cover, and the second arc-shaped filter cover is made of iron.

[0009] Furthermore, the rotary adjustment assembly includes a support plate, which is fixedly connected to the inside of the housing. A rotating rod is rotatably connected to the upper side of the support plate, and the upper side of the rotating rod extends to the outside of the housing.

[0010] Furthermore, a micro servo motor is fixedly connected to one side of each of the two U-shaped brackets, and the output end of the micro servo motor is fixedly connected to one of the rotating shafts.

[0011] Furthermore, the box body is provided with an installation groove, and a collection box is fixedly connected inside the box body. The upper and right sides of the collection box are open, and a drawer is slidably connected inside the collection box and extends to the outside of the installation groove.

[0012] Furthermore, a plurality of telescopic damping rods are fixedly connected to the lower side of the box body, and a circular plate is fixedly connected to the lower side of the plurality of telescopic damping rods. A return spring is sleeved on the outer side of the plurality of telescopic damping rods. The upper side of the return spring is fixedly connected to the lower side of the box body, and the other end of the return spring is fixedly connected to the upper end of the circular plate.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model discloses a wastewater treatment device for polyamide fiber production. It uses a second arc-shaped filter cover to filter large impurities such as fibers and suspended solids from the wastewater, further reducing the likelihood of these impurities directly contacting and clogging the filter screen. Simultaneously, when the second arc-shaped filter cover becomes clogged, operators can rotate the adjustment assembly to rotate the U-shaped supports on both sides and the second arc-shaped filter cover, allowing one of the second arc-shaped filter covers to align with the lower side of the first arc-shaped filter cover. This enables rapid replacement of the second arc-shaped filter cover, reducing the difficulty of replacement and ensuring the continuity of wastewater treatment operations.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-5As shown, a wastewater treatment device for polyamide fiber production includes a housing 1, which has a hollow structure. An inlet pipe 2 is fixedly connected to the upper side of the housing 1 and extends into the housing 1. A first arc-shaped filter cover 8 is fixedly connected inside the housing 1 and is connected to the inlet pipe 2. A rotary adjustment group is installed inside the housing 1. U-shaped brackets 13 are fixedly connected to both sides of the rotary adjustment group. A second arc-shaped filter cover 9 is rotatably connected inside the two U-shaped brackets 13. Multiple round holes are opened on the two second arc-shaped filter covers 9. One of the second arc-shaped filter covers 9 is connected to the first arc-shaped filter cover 8. A filter screen 15 is fixedly connected inside the housing 1. Rotating shafts are fixedly connected to both sides of the second arc-shaped filter cover 9. Rotating holes are opened on both sides of the U-shaped brackets 13, and the rotating shafts are rotatably connected to the rotating holes. An outlet pipe 7 is fixedly connected to one side of the housing 1 and extends into the housing 1.

[0024] During operation, wastewater from polyamide fiber production enters the tank 1 through the inlet pipe 2. Since the inlet pipe 2 is connected to the first arc-shaped filter cover 8, the wastewater then enters the second arc-shaped filter cover 9. The second arc-shaped filter cover 9 filters out large impurities such as fibers and suspended solids from the wastewater. The filtered wastewater then flows through the round holes on the second arc-shaped filter cover 9 to the filter screen 15 for secondary filtration. Finally, the wastewater is discharged through the outlet pipe 7, further reducing the direct contact between large fibers, suspended solids, and other impurities and the filter screen 15, thus preventing clogging. Simultaneously, when the second arc-shaped filter cover 9 becomes clogged, the operator rotates the rotating adjustment group to rotate the U-shaped supports 13 on both sides and the second arc-shaped filter cover 9, allowing one of the second arc-shaped filter covers 9 to align with the lower side of the first arc-shaped filter cover 8. This enables rapid replacement of the second arc-shaped filter cover 9, reducing the difficulty of replacement and ensuring the continuity of the wastewater treatment process.

[0025] like Figures 2-4 As shown, a magnet 10 is fixedly connected to the lower side of the first arc-shaped filter cover 8, and the second arc-shaped filter cover 9 is made of iron. When in use, since the magnet 10 is fixed to the lower side of the first arc-shaped filter cover 8 and the second arc-shaped filter cover 9 is made of iron, the second arc-shaped filter cover 9 will be attracted by the magnet 10 during rotation and maintain a relatively stable position, ensuring the stability and continuity of filtration.

[0026] like Figure 3 , Figure 4 , Figure 5As shown, the rotary adjustment assembly includes a support plate 16, which is fixedly connected to the inside of the housing 1. A rotating rod 3 is rotatably connected to the upper side of the support plate 16, and the upper side of the rotating rod 3 extends to the outside of the housing 1. In use, the operator holds the part of the rotating rod 3 located on the outside of the housing 1 and rotates the rotating rod 3. Since the rotating rod 3 is rotatably connected to the support plate 16, and the rotating rod 3 drives the U-shaped bracket 13, which is connected to the rotating rod 3, the rotation of the rotating rod 3 can drive the rotating rods 3 on both sides to rotate synchronously. This allows the unblocked rotating rod 3 to be rotated to a position connected to the housing 1. At this time, the wastewater can continue to be filtered through the new rotating rod 3, ensuring the continuous operation of the wastewater treatment device.

[0027] like Figure 3 , Figure 4 , Figure 5 As shown, a micro servo motor 14 is fixedly connected to one side of each of the two U-shaped brackets 13. The output end of the micro servo motor 14 is fixedly connected to one of the rotating shafts. When in use, the operator starts the micro servo motor 14, which drives the replaced rotating rod 3 to rotate. During the rotation, the impurities inside the second arc-shaped filter cover 9 are poured out, thereby cleaning the replaced second arc-shaped filter cover 9 for easy use next time.

[0028] like Figure 3 , Figure 4 As shown, the housing 1 has an installation groove, and a collection box 11 is fixedly connected inside the housing 1. The upper and right sides of the collection box 11 are open. A drawer 12 is slidably connected inside the collection box 11 and extends to the outside of the installation groove. During use, when rotating and cleaning, the impurities in the second arc-shaped filter cover 9 will be cleaned into the drawer 12. When the impurities in the drawer 12 accumulate to a certain extent, it can be directly pulled out from the installation groove for centralized processing of the collected impurities. After cleaning, the drawer 12 can be pushed back to its original position.

[0029] like Figure 1 , Figure 4 As shown, multiple telescopic damping rods 5 are fixedly connected to the lower side of the housing 1. A circular plate 4 is fixedly connected to the lower side of the multiple telescopic damping rods 5. A return spring 6 is sleeved on the outer side of the multiple telescopic damping rods 5. The upper side of the return spring 6 is fixedly connected to the lower side of the housing 1, and the other end of the return spring 6 is fixedly connected to the upper end of the circular plate 4. When the device vibrates, the housing 1 moves downward, the return spring 6 contracts, and the telescopic damping rods 5 are compressed. The return spring 6 consumes the energy generated by the vibration through its own damping characteristics, slows down the descent speed of the housing 1, increases the relative stability of the device during operation, reduces the impact of vibration on the connection of various components and the filtration effect, and extends the service life of the device.

[0030] The working principle of this utility model is as follows: During use, the wastewater from polyamide fiber production enters the tank 1 through the inlet pipe 2. Since the inlet pipe 2 is connected to the first arc-shaped filter cover 8, the wastewater then enters the second arc-shaped filter cover 9. The second arc-shaped filter cover 9 filters out large impurities such as fibers and suspended solids in the wastewater. The filtered wastewater then flows through the round holes on the second arc-shaped filter cover 9 into the filter screen 15 for secondary filtration. Finally, the wastewater is discharged through the outlet pipe 7, further reducing the phenomenon of large fibers, suspended solids, and other impurities directly contacting the filter screen 15 and causing it to become clogged. At the same time, when the second arc-shaped filter cover 9 becomes clogged, the operator rotates the rotating adjustment group to drive the U-shaped brackets 13 on both sides and the second arc-shaped filter cover 9 to rotate, so that one of the second arc-shaped filter covers 9 is connected to the lower side of the first arc-shaped filter cover 8, thereby realizing the quick replacement of the second arc-shaped filter cover 9, reducing the difficulty of replacing the second arc-shaped filter cover 9, and ensuring the continuity of the equipment's wastewater treatment work.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
