Description

Technical Field

[0001] This utility model relates to the field of polypropylene spinning production technology, specifically to an impurity filtration device for preparing heat-resistant and pollution-free polypropylene spinning oil. Background Technology

[0002] Polypropylene spinning oil is an auxiliary agent used in spinning processing. It reduces the electrostatic attraction between fibers by reducing friction between fibers, thereby improving the smoothness of spinning. In order to ensure that the oil can be used normally, it is necessary to use filtration equipment to filter out the impurities it contains to prevent them from affecting the spinning process.

[0003] A polypropylene spinning oil impurity removal and filtration device, with announcement number CN221771655U, is based on a support frame. A filter barrel is fixedly connected to the top of the support frame, and a motor is fixedly connected to the bottom of the filter barrel. A turntable is rotatably connected to the inside of the filter barrel, and a stirring blade is fixedly connected to the top of the turntable. When using this filtration device, the structure of the discharge and return water components allows for the opening of solenoid valve one and the closing of solenoid valve two after filtration to test the quality of the polypropylene spinning oil. If impurities are still present, solenoid valve one is closed and solenoid valve two is opened to start the delivery pump, injecting the polypropylene spinning oil into the return material pipe through the return water pipe and hose for further filtration. After filtration is complete, the top cover can be rotated open to remove filter screen one and filter screen two for cleaning and replacement, making the device easier to use.

[0004] The polypropylene spinning oil removal and filtration device described above also has problems. The device filters through filter screen one and filter screen two. As the usage time increases, impurities accumulate on their surfaces, which reduces the filtration efficiency and thus reduces the efficiency of polypropylene spinning production and processing.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0027] Example 1:

[0028] Please see Figures 1-2 This is the first embodiment of the present utility model.

[0029] This embodiment provides an impurity filtration device for preparing heat-resistant and pollution-free polypropylene spinning oil, comprising:

[0030] The cylinder 1 has a filter mechanism 2 installed inside the cylinder 1, a drainage mechanism 4 installed at the bottom of the cylinder 1, and a detection mechanism 9 installed at the bottom of the cylinder 1.

[0031] The filter mechanism 2 includes a filter cylinder 21 fixed to the top of the inner side of the cylinder 1. A hollow shaft 22 is rotatably mounted inside the filter cylinder 21. A through hole 23 is opened on the circumferential surface of the hollow shaft 22. A spiral blade 24 is fixed on the circumferential surface of the hollow shaft 22. A support plate 25 is fixed at the top edge of the cylinder 1. A servo motor 26 is fixed on the bottom side of the support plate 25. A small pulley 27 is fixed through the output end of the servo motor 26 and passes through the support plate 25. A large pulley 28 is fixed on the top circumferential surface of the hollow shaft 22. A belt 29 is fitted on the small pulley 27 and the large pulley 28.

[0032] Specifically, a feed inlet 3 is provided on the top side of the cylinder 1, located on the top side of the filter cylinder 21. A water pump 5 is fixed on the top side of the cylinder 1, and an output valve 7 is fixed on the bottom circumferential surface of the cylinder 1. The output end of the water pump 5 is connected to the top of the inner side of the cylinder 1 through a conduit 6, and the input end of the water pump 5 is connected to the top of the inner side of the output valve 7 through an oil supply pipe 8.

[0033] Furthermore, with the assistance of the water pump 5, the oil inside the cylinder 1 can be transported back to the inside of the filter cylinder 21, and impurities in the oil can be thoroughly removed through circulating filtration.

[0034] In use, the servo motor 26 drives the small pulley 27 at the output end to rotate. With the cooperation of the large pulley 28 and the belt 29, the hollow shaft 22 is driven to rotate. At this time, the oil is added through the feed port 3. The hollow shaft 22 drives the spiral blades 24 to rotate, thereby causing the oil to pass through the filter cylinder 21 and filter out the impurities it contains. At the same time, the spiral blades 24 are in contact with the inner wall of the filter cylinder 21, which can scrape off the impurities attached to its surface, thus ensuring that the filtration efficiency of the device does not decrease, and also reducing the frequency of cleaning and maintenance of the device. Afterwards, with the cooperation of the water pump 5, the oil inside the cylinder 1 can be transported back to the inside of the filter cylinder 21 through the oil delivery pipe 8 and the conduit 6. The impurities in the oil are completely removed through circulation filtration. After filtration is completed, the output valve 7 can be opened to discharge the oil for use.

[0035] In summary, through the structure of the filter mechanism 2, the hollow shaft 22 drives the spiral blades 24 to rotate, which not only promotes the filtration of oil, but also prevents impurities from accumulating on the surface of the filter cartridge 21, thus preventing a decrease in the filtration efficiency of the device and reducing the frequency of cleaning and maintenance of the device, thereby making the filtration efficiency of oil higher.

[0036] Example 2:

[0037] Please see Figures 3-4 This is the second embodiment of the present utility model.

[0038] Specifically, the drainage mechanism 4 includes a drain pipe 41 fixed at the bottom of the filter cylinder 21, a drain outlet 42 on the bottom circumferential surface of the drain pipe 41, a piston 43 slidably installed inside the drain pipe 41, an electric telescopic rod 44 fixed at the bottom of the drain pipe 41, the top end of the electric telescopic rod 44 passing through the drain pipe 41 and fixedly connected to the piston 43, a sleeve 47 slidably fitted at the bottom of the filter cylinder 21, cylinders 45 symmetrically fixed at the bottom of the cylinder 1, a round rod 46 slidably installed inside the cylinder 45, the top end of the round rod 46 passing through the cylinder 1 and fixedly connected to the sleeve 47.

[0039] Furthermore, through the structure of piston 43 and sleeve 47, drain pipe 41 can be opened and filter cartridge 21 can be closed when cleaning is required, so as to clean and maintain the device.

[0040] Specifically, the testing mechanism 9 includes a DC power supply 91 fixed to the bottom side of the cylinder 1, a controller 92 fixed to the bottom side of the cylinder 1 on one side of the DC power supply 91, the DC power supply 91 and the controller 92 are connected by a wire 93, a metal plate 95 is fixed to the bottom side of the piston 43, and metal wires 94 are symmetrically inserted into the bottom side of the drain pipe 41, and the metal wires 94 are respectively connected to the two ends of the wires 93.

[0041] Furthermore, through the structure of the metal plate 95 and the metal wire 94, the controller 92 is connected to the cylinder 45 by signal. When the piston 43 moves to the bottom side of the drain pipe 41, the controller 92 simultaneously controls the cylinder 45 to close the filter cartridge 21 for cleaning.

[0042] In use, the electric telescopic rod 44 is controlled to retract, thereby driving the piston 43 to slide downward inside the drain pipe 41 until the drain outlet 42 at the bottom of the drain pipe 41 opens. At this time, the metal plate 95 at the bottom of the piston 43 contacts the metal wires 94 on both sides, connecting the wires 93 into a closed circuit, thereby causing the controller 92 to receive an electrical signal and control the cylinder 45 to extend its inner round rod 46, thereby driving the sleeve 47 to rise and fit onto the circumference of the filter cylinder 21 to seal it. At this time, clean water can be delivered to the inside of the hollow shaft 22, and water can be sprayed out from the through hole 23 to rinse the inside of the filter cylinder 21, thereby removing impurities from the inside of the filter cylinder 21. Afterwards, the wastewater is discharged from the drain outlet 42 at the bottom of the drain pipe 41, completing the cleaning operation.

[0043] In summary, through the structure of the drainage mechanism 4 and the detection mechanism 9, the sleeve 47 can be automatically controlled to close the filter cylinder 21 during cleaning, preventing wastewater from flowing into the inner side of the cylinder 1 and affecting the quality of subsequent oil filtration, thus enabling the device to achieve automatic cleaning.
