Description

Technical Field

[0001] This utility model relates to the field of ultraviolet absorber production technology, specifically to an ultraviolet absorber liquid filtration device. Background Technology

[0002] Ultraviolet absorbers are high-performance, highly effective anti-aging additives that absorb ultraviolet light in the 240-340nm range (with particularly strong absorption in the 270-330nm range). They are characterized by light color, non-toxicity, good compatibility, low migration, and ease of processing. They provide maximum protection for polymers, help reduce color, delay yellowing, and inhibit the loss of physical properties.

[0003] Chinese Patent CN221385591U discloses a filtration device for ultraviolet absorber liquid, relating to the field of ultraviolet absorbers. The device includes a sedimentation tank, a buffer tank, and a filter. An overflow port is located at the top of one side of the sedimentation tank, and a buffer tank is located on the same side. An overflow pipe is connected between the overflow port and the buffer tank. A level sensor and a water pump are located at the top of the buffer tank. A filter is located on one side of the buffer tank, and a filter column is located inside the filter. A connecting pipe connects the buffer tank, the water pump, and the filter. This invention, through the design of the sedimentation tank, can pre-treat solid particles in the liquid. The design of the buffer tank, level sensor, and water pump allows for the delivery of a fixed amount of liquid to the filter for filtration, thereby reducing the processing load on the filter, increasing the equipment's service life, ensuring the efficiency of filtration of the ultraviolet absorber liquid, and increasing the practicality of the device.

[0004] However, the above technical solutions only use the design of buffer tanks, level sensors and water pumps to deliver a certain amount of liquid to the filter for filtration, which can alleviate the processing load of the filter, increase the service life of the equipment and ensure the efficiency of filtration of ultraviolet absorber liquid. However, the filtration process mainly relies on a single filter and filter column for filtration, lacking a pre-treatment and graded filtration mechanism. This makes it easy for fine particles, colloids or flocculents to enter the filter column, causing problems such as blockage, increased pressure difference and decreased filtration efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a filtration device for ultraviolet absorber liquid.

[0006] The technical solution of this utility model is as follows: A UV absorber liquid filtration device includes a sedimentation tank with an overflow pipe connected to its top and a slag discharge pipe connected to its bottom; a filter assembly connected to the overflow tank at one end, comprising an inlet pipe, a branch pipe, filter elements, and an outlet pipe, with the inlet and outlet pipes respectively connected to the two ends of a rectangular branch pipe; two parallel filter elements connected to the branch pipe, with a valve connected to the branch pipe to control the different filter elements for filtration; and a sedimentation assembly connected to the sedimentation tank, comprising a support frame, guide plates, telescopic devices, and connectors. The support frame is connected to the top of the sedimentation tank, and multiple telescopic devices are connected to the support frame. The telescopic ends of the telescopic devices pass through the support frame and are rotatably connected to a connecting rod through a through hole at the top of the sedimentation tank. The connecting rod is rotatably connected to the guide plates, which are arrayed along the length of the sedimentation tank and are located on both side walls of the sedimentation tank. Initially, the guide plates are inclined to accelerate the sedimentation of solid substances. When driven by the telescopic devices and connectors, the guide plates oscillate back and forth to increase the drug mixing speed.

[0007] Preferably, the filter element consists of multiple parallel filters, each with a different pore size in its filter element.

[0008] Preferably, the connector consists of positioning rods and mating columns. Each guide plate is connected to the mating columns on both sides. Two symmetrically arranged positioning rods are arranged on both sides of the guide plate. The positioning rods are provided with through holes that are rotatably connected to the mating columns.

[0009] Preferably, a protective box is fitted on the outside of the positioning rod, and the protective box encloses the connection part between the mating column and the positioning rod.

[0010] Preferably, the initial tilt angle of the deflector is 45-50 degrees.

[0011] Preferably, the internal space of the settling tank has a rectangular cross-section to match the shape of the guide plate, and the bottom of the settling tank has a conical bottom surface, which is the same as the center of the slag discharge pipe.

[0012] Preferably, the filtration assembly also includes a PLC controller connected to the sedimentation tank and electrically connected to the valve; and a flow meter connected to the inlet pipe and electrically connected to the PLC controller.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: In this invention, the guide plates are arrayed along the length of the settling tank and are initially inclined, which can accelerate the natural sedimentation of solid substances. Furthermore, the guide plates can swing back and forth under the drive of the telescopic device and connecting parts, thereby increasing the drug mixing speed of the liquid, promoting particle flocculation and uniform distribution. The mechanical swinging mode actively disturbs the flow state of the liquid, which not only improves the sedimentation efficiency of solid particles in the settling tank, but also breaks up any flocs or sediment layers that may form, allowing the liquid to enter the subsequent filtration process more evenly, further ensuring the efficient operation of the filtration components.

[0015] Example 1, as Figures 1-4 As shown, the present invention proposes a UV absorber liquid filtration device, including a sedimentation tank 1, an overflow pipe 2, a slag discharge pipe 3, a filter assembly, and a sedimentation assembly. The top of the sedimentation tank 1 is connected to the overflow pipe 2, and the bottom of the sedimentation tank 1 is connected to the slag discharge pipe 3. The slag discharge pipe 3 is equipped with a valve, which is connected to a PLC controller 16. One end of the filter assembly is connected to the overflow tank. The filter assembly includes an inlet pipe 4, a diversion pipe 5, filter elements 6, and an outlet pipe 7. The inlet pipe 4 and the outlet pipe 7 are respectively connected to the two ends of the rectangular diversion pipe 5. Two parallel filter elements 6 are connected to the diversion pipe 5. A valve is connected to the diversion pipe 5 to control the different filter elements 6 to perform filtration operations. The filter element 6 consists of multiple parallel filters, each with a different pore size. The different filter elements in the filter element 6 can filter impurities of different particle sizes, thereby reducing the problem of short service life caused by a single filter element. The precipitation assembly is connected to the precipitation tank 1. The precipitation assembly includes a support frame 8, a guide plate 9, a telescopic device 10, and a connector 11. The support frame 8 is connected to the top of the precipitation tank 1, and multiple telescopic devices 10 are connected to the support frame 8. The telescopic devices 10 can be, but are not limited to, cylinders and electric push rods, both of which are connected to external equipment to provide the necessary air source or power. The telescopic end of the telescopic device 10 passes through the support frame 8 and is rotatably connected to the hinge seat of the top through hole of the precipitation tank 1 with a connecting rod 12. The connecting rod 12 is rotatably connected to the hinge seat of the guide plate 9. The guide plates 9 are arranged in an array along the length of the precipitation tank 1 and are set on the two side walls of the precipitation tank 1. In the initial state, the guide plates 9 are in an inclined state to accelerate the precipitation of solid substances. When the guide plates 9 are driven by the telescopic devices 10 and the connector 11, they swing back and forth to increase the drug mixing speed.

[0016] Example 2, as Figure 2 , Figure 3 As shown, this utility model proposes a UV absorber liquid filtration device. Compared with Embodiment 1, this embodiment describes the detailed structure of the precipitation component. The connector 11 consists of positioning rods 13 and mating posts 14. Each guide plate 9 is connected to the mating posts 14 on both sides. Two symmetrically arranged positioning rods 13 are arranged on both sides of the guide plate 9. The positioning rods 13 are provided with through holes that are rotatably connected to the mating posts 14. A protective box 15 is fitted on the outside of the positioning rod 13. The protective box 15 encloses the connection between the mating column 14 and the positioning rod 13. The protective box 15 provides protection by preventing impurities from entering between the mating column 14 and the positioning rod 13 and affecting their rotation. In its initial state, the guide plate 9 has an inclination angle of 45-50 degrees. Under normal conditions, the guide plate 9 accelerates the sedimentation effect through its own inclination angle, while in use it can swing to make the water slosh and accelerate the mixing of flocculants. The internal space of the sedimentation tank 1 has a rectangular cross-section to match the shape of the guide plate 9. The bottom of the sedimentation tank 1 is a conical bottom surface, and the center of the conical bottom surface is the same as that of the slag discharge pipe 3. The conical bottom surface can guide impurities towards the center, which facilitates discharge and avoids the formation of dead corners.

[0017] Example 3, as Figure 1 As shown, this utility model proposes a UV absorber liquid filtration device. Compared with Embodiment 2, this embodiment describes the detailed structure of the filtration component. The filtration assembly also includes a PLC controller 16 and a flow meter 17. The PLC controller 16 is connected to the sedimentation tank 1 and is electrically connected to the valve. The PLC controller 16 controls the valve to start and stop by receiving signals, thereby directing the water flow to different branches of the U-shaped diversion pipe 5 and switching the filter element 6 in time to prevent the filtration effect of the filter element 6 from being compromised. The flow meter 17 is connected to the inlet pipe 4 and is electrically connected to the PLC controller 16. The flow meter 17 is an electromagnetic flow meter to detect changes in flow rate, and it can send signals to the PLC controller 16 to control the valve.

[0018] In summary, when using this invention, the ultraviolet absorber liquid to be filtered first enters the sedimentation tank 1 through an external conveying pipe. After entering from the top of the sedimentation tank 1, the liquid remains in the sedimentation tank 1 for preliminary sedimentation. During this preliminary sedimentation, the guide plate 9 is initially tilted, guiding the liquid to form a specific flow path, slowing down the flow rate, and causing the denser solid particles to gradually settle to the bottom of the sedimentation tank 1 under gravity, achieving preliminary solid-liquid separation. In some cases, when flocculants or other drugs that accelerate sedimentation are added to the sedimentation tank 1, the telescopic device 10 moves the connecting rod 12 up and down through its telescopic movement, thereby driving the guide plate 9 to oscillate back and forth around its fixed axis with the side wall of the sedimentation tank 1, promoting uniform mixing of particles and liquid, assisting solid particles to settle faster, and improving sedimentation efficiency. The settled liquid is discharged from the overflow pipe 2 and enters the filter assembly for graded filtration. The liquid first enters the inlet pipe 4 through the overflow pipe 2, and then flows into the diversion pipe 5 connected to the inlet pipe 4. The liquid first passes through the filter element with a larger pore size to intercept larger particles and flocculent matter, and then passes through the filter element with a smaller pore size to further remove fine particles and colloids, realizing multi-stage and fine filtration, effectively improving the filtration effect and reducing the risk of clogging of a single filter element. The PLC controller 16 controls the valve to open or close the corresponding filter element 6 according to the flow signal detected by the flow meter 17 installed on the inlet pipe 4, thereby realizing the selective use, alternating filtration or automatic switching of different filter elements 6, balancing the workload of each filter element, and avoiding local overuse that leads to increased pressure difference or decreased filtration efficiency. The filtered liquid is discharged through the outlet pipe 7. The clean liquid after staged filtration finally flows out from the outlet pipe 7 and enters the subsequent process flow or collection container to complete the entire filtration process. The sediment at the bottom of the sedimentation tank 1 is periodically discharged through the slag discharge pipe 3.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
