Description

Technical Field

[0001] This utility model relates to the technical field of impurity removal and screening devices, and in particular to an impurity removal and screening device for polyester fiber raw materials. Background Technology

[0002] Impurity removal screening devices are mainly used to remove impurities from raw materials, such as dust, particles, and fiber fragments, in order to improve the purity of polyester fibers.

[0003] When using a cleaning and screening machine to remove impurities from polyester fiber raw materials, the raw materials are usually placed directly into the feed hopper and then enter the machine, falling onto the filter screen. After the filter screen cleans and filters out large particles of impurities, the filtered polyester fibers are discharged from the discharge pipe, while the impurities filtered off the screen are discharged from the first drain pipe, thus achieving the effect of removing impurities. However, since the filter screen can only remove larger particles of impurities, some smaller and lighter particles in the polyester fiber raw materials will still remain in the raw materials. This results in insufficient screening by traditional cleaning and screening machines, reducing the efficiency of the cleaning and screening process. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a purification and screening device for polyester fiber raw materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a screening device for removing impurities from polyester fiber raw materials, comprising a screening machine, wherein a filter screen is fixedly connected to the inner wall of the screening machine, a first drain pipe is connected to one side of the filter screen and one side of the inner wall of the screening machine, a discharge pipe is provided at the bottom of the screening machine, and electromagnetic valves are provided inside both the first drain pipe and the discharge pipe, a cover is provided at the top of the screening machine, a feed hopper is provided on the outer surface of the cover, and a secondary screening device is provided on the inner wall of the screening machine. The secondary screening device enables the polyester fiber raw materials to undergo secondary screening and impurity removal during the screening process on the filter screen, thereby removing smaller and lighter impurities mixed in with the raw materials, making the impurity removal and screening more thorough and improving the efficiency of the impurity removal and screening process.

[0006] The effect achieved by the above components is as follows: When using the impurity removal screening machine to remove impurities from polyester fiber raw materials, the polyester fiber raw materials are usually placed directly into the feed hopper and then enter the interior of the impurity removal screening machine and fall onto the filter screen. After the large particles of impurities are cleaned and filtered by the filter screen, a secondary screening device is used to perform a second thorough impurity removal screening operation to improve the efficiency of impurity removal screening. The polyester fibers after impurity removal are discharged from the discharge pipe, while the impurities filtered off the filter screen are discharged from the first sewage discharge pipe, thus achieving the effect of impurity removal screening.

[0007] Preferably, the secondary screening device includes an air jet frame, which is disposed at the bottom of the filter screen and passes through and is connected to the inner wall of the impurity removal screening machine. An air pump is fixedly connected to the air inlet of the air jet frame. One side of the air pump is fixedly connected to the outer surface of the impurity removal screening machine. A first motor is fixedly connected to one side of the filter screen. A round shaft is fixedly connected to the output end of the first motor. The round shaft passes through and is connected to the filter screen. A stirring rod is symmetrically rotatably connected to the outer surface of the round shaft. A second drain pipe passes through and is connected to the top of the machine cover.

[0008] The effects achieved by the above-mentioned components are as follows: By setting up a secondary screening device, when the polyester fiber raw material falls onto the filter screen for impurity removal and screening, the air pump and the first motor can be started simultaneously. The first motor can drive the round shaft and the stirring rod to rotate on the top of the filter screen, stirring the polyester fiber raw material falling onto the filter screen, so that the polyester fiber raw material can fully contact the filter screen and accelerate the efficiency of the filter screen for impurity removal. At the same time, when the air pump draws external air into the air jet frame and blows it onto the filter screen, under the stirring and pushing of the stirring rod, the air blown out by the air jet frame can fully contact the polyester fiber raw material, blowing away the smaller and lighter impurities mixed in with it, and blowing them out through the second drain pipe, thus performing a secondary and thorough impurity removal and screening operation on the polyester fiber, improving the efficiency of impurity removal and screening.

[0009] Preferably, scrapers are symmetrically fixedly connected to the outer surface of the circular shaft, and the position of the scraper with the greatest degree of bending is on the same arc line as the inlet of the first sewage pipe.

[0010] The effect achieved by the above components is that, by setting up a scraper, the impurities filtered down from the filter screen can be accurately scraped into the inner wall of the first drain pipe, making it easier for the debris to be discharged.

[0011] Preferably, a bearing is fixedly connected to the outer surface of the circular shaft, and the outer ring of the bearing is fixedly connected to one side of the filter screen.

[0012] The effect achieved by the above components is that by setting bearings, rotational wear between the shaft and the filter screen can be reduced, the shaft can be rotated more easily, and the service life of both can be increased.

[0013] Preferably, a baffle is fixedly connected to the bottom of the filter screen, and the first motor is disposed inside the baffle.

[0014] The effect achieved by the above components is that by setting up a baffle, the first motor can be covered, preventing the polyester fibers filtered by the filter screen from falling onto the first motor and accumulating, thus facilitating the discharge of the polyester fibers.

[0015] Preferably, a rotating mechanism is provided between one end of the stirring rod and the inner wall of the impurity removal screening machine. The rotating mechanism includes a second annular plate. A bevel gear is fixedly connected to one end of the stirring rod. A bevel gear ring block is fixedly connected to the inner wall of the impurity removal screening machine. The bevel gear meshes with the bevel gear ring block. First annular plates are fixedly connected to both sides of the bevel gear ring block on the inner wall of the impurity removal screening machine. The two sides of the second annular plate are rotatably connected to one side of the two first annular plates, respectively. One end of each of the two stirring rods is passed through and connected to one side of the second annular plate.

[0016] The effect achieved by the above components is as follows: by setting up a rotating mechanism, when the circular shaft drives the stirring rod to move in a circular motion around the circular shaft, it will also drive the second circular ring plate to slide on the two first circular ring plates, and drive the bevel gear to move in a circular motion. At the same time, the bevel gear will mesh and rotate on the bevel gear ring block, which will drive the stirring rod to rotate, lifting the polyester fiber raw material filtered on the filter screen, so that it can fully contact the air blown out by the air jet frame, blowing away the smaller and lighter impurities mixed in with it, and blowing them out through the second drain pipe, thus performing a secondary thorough impurity removal and screening operation on the polyester fiber, improving the efficiency of impurity removal and screening.

[0017] Preferably, the inner wall of the feed hopper is provided with an anti-clogging device, the anti-clogging device including a second motor, one side of the second motor is fixedly connected to one side of the feed hopper, a round rod is fixedly connected to the output end of the second motor, the round rod is connected through the inner wall of the feed hopper, and a number of blades are fixedly connected to the outer surface of the round rod.

[0018] The effect achieved by the above components is as follows: by setting up an anti-blocking device, after the polyester fiber raw material is put into the feed hopper, the second motor can be started to drive the round shaft and blades to rotate inside the feed hopper, so that the internal outlet of the feed hopper is always in an active state, avoiding the accumulation and jamming of the polyester fiber raw material, thereby avoiding blockage. At the same time, controlling the rotation speed of the second motor can also control the feeding speed of the polyester fiber, which can improve the impurity removal efficiency of the impurity removal screening machine and make it convenient to use.

[0019] Preferably, a protective cover is fixedly connected to one side of the feed hopper, and the second motor is disposed inside the protective cover.

[0020] The effect achieved by the above-mentioned components is that by setting up a protective cover, the outer surface of the second motor can be protected, making it less likely to be impacted during use or transportation, thus avoiding damage.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

Detailed Implementation

[0028] Example 1, such as Figure 1-4As shown, a screening device for removing impurities from polyester fiber raw materials includes a screening machine 1. A filter screen 4 is fixedly connected to the inner wall of the screening machine 1. A first drain pipe 5 is connected to one side of the filter screen 4 and one side of the inner wall of the screening machine 1. A discharge pipe 6 is provided at the bottom of the screening machine 1. Electromagnetic valves are installed inside both the first drain pipe 5 and the discharge pipe 6. A cover 7 is provided at the top of the screening machine 1. A feed hopper 8 is provided on the outer surface of the cover 7. A secondary screening device 2 is provided on the inner wall of the screening machine 1. The secondary screening device 2 can perform secondary screening and impurity removal on the polyester fiber raw materials during the impurity removal screening process on the filter screen 4, and remove the smaller and lighter impurities mixed in with the raw materials, making the impurity removal screening more thorough and improving the efficiency of the impurity removal screening process. When using the impurity removal screening machine 1 to remove impurities from polyester fiber raw materials, the polyester fiber raw materials are usually placed directly into the feed hopper 8 and then enter the impurity removal screening machine 1 and fall onto the filter screen 4. After the large particles of impurities are cleaned and filtered by the filter screen 4, a secondary screening device 2 is used to perform a second thorough impurity removal screening operation to improve the efficiency of impurity removal screening. The filtered and impurity-removed polyester fibers will be discharged from the discharge pipe 6, while the impurities filtered off the filter screen 4 will be discharged from the first sewage pipe 5, thus achieving the effect of impurity removal screening.

[0029] Reference Figure 2 and Figure 3 As shown, this embodiment discloses a secondary screening device 2 including an air jet frame 21. The air jet frame 21 is disposed at the bottom of the filter screen 4 and is connected through the inner wall of the impurity removal screening machine 1. An air pump 22 is fixedly connected to the air inlet of the air jet frame 21. One side of the air pump 22 is fixedly connected to the outer surface of the impurity removal screening machine 1. A first motor 24 is fixedly connected to one side of the filter screen 4. A round shaft 25 is fixedly connected to the output end of the first motor 24. The round shaft 25 is connected through the filter screen 4. A stirring rod 26 is symmetrically rotatably connected to the outer surface of the round shaft 25. A second drain pipe 210 is connected through the top of the machine cover 7. When the polyester fiber raw material falls onto the filter screen 4 for impurity removal and screening, the air pump 22 and the first motor 24 can be started simultaneously. The first motor 24 can drive the round shaft 25 and the stirring rod 26 to rotate on the top of the filter screen 4, stirring the polyester fiber raw material falling onto the filter screen 4, so that the polyester fiber raw material can fully contact the filter screen 4 and accelerate the screening and impurity removal efficiency of the filter screen 4. At the same time, when the air pump 22 draws external air into the air jet frame 21 and blows it onto the filter screen 4, under the stirring and pushing of the stirring rod 26, the air blown out by the air jet frame 21 can fully contact the polyester fiber raw material, blowing away the smaller and lighter impurities mixed in with it, and blowing them out from the second drain pipe 210, performing a second thorough impurity removal and screening operation on the polyester fiber, improving the impurity removal and screening efficiency.

[0030] Reference Figure 2and Figure 3 As shown, this embodiment discloses that scrapers 27 are symmetrically fixedly connected to the outer surface of the circular shaft 25, and the position of the scraper 27 with the greatest curvature is on the same arc line as the inlet of the first drain pipe 5. By setting the scraper 27, the impurities filtered off the filter screen 4 can be accurately scraped into the inner wall of the first drain pipe 5, facilitating the discharge of debris. A bearing 28 is fixedly connected to the outer surface of the circular shaft 25, and the outer ring of the bearing 28 is fixedly connected to one side of the filter screen 4. By setting the bearing 28, the rotational wear between the circular shaft 25 and the filter screen 4 can be reduced, facilitating the rotation of the circular shaft 25 and improving the service life of both. A baffle 29 is fixedly connected to the bottom of the filter screen 4, and the first motor 24 is located inside the baffle 29. By setting the baffle 29, the first motor 24 can be covered, preventing the polyester fibers filtered off the filter screen 4 from falling onto the first motor 24 and accumulating, thus facilitating the discharge of polyester fibers.

[0031] Reference Figure 2 and Figure 3 As shown, this embodiment discloses a rotating mechanism 23 provided between one end of the stirring rod 26 and the inner wall of the impurity removal screening machine 1. The rotating mechanism 23 includes a second annular plate 234. One end of the stirring rod 26 is fixedly connected to a bevel gear 231. The inner wall of the impurity removal screening machine 1 is fixedly connected to a bevel gear ring block 232. The bevel gear 231 meshes with the bevel gear ring block 232. The inner wall of the impurity removal screening machine 1 is fixedly connected to both sides of the bevel gear ring block 232. The two sides of the second annular plate 234 are rotatably connected to one side of the two first annular plates 233 respectively. One end of the two stirring rods 26 is passed through and connected to one side of the second annular plate 234. When the circular shaft 25 drives the stirring rod 26 to move in a circular motion around the circular shaft 25, it also drives the second circular ring plate 234 to slide on the two first circular ring plates 233, and drives the bevel gear 231 to move in a circular motion. At the same time, the bevel gear 231 will mesh and rotate on the bevel gear ring block 232, which will drive the stirring rod 26 to rotate. This will lift the polyester fiber raw material filtered on the filter screen 4, so that it can fully contact the air blown out by the air jet frame 21, blow away the smaller and lighter impurities mixed in with it, and blow them out from the second drain pipe 210. This will perform a secondary thorough impurity removal and screening operation on the polyester fiber, thereby improving the efficiency of impurity removal and screening.

[0032] Reference Figure 4As shown, this embodiment discloses an anti-blocking device 3 installed on the inner wall of the feed hopper 8. The anti-blocking device 3 includes a second motor 31, one side of which is fixedly connected to one side of the feed hopper 8. A round rod 32 is fixedly connected to the output end of the second motor 31, and the round rod 32 passes through and connects to the inner wall of the feed hopper 8. Several blades 33 are fixedly connected to the outer surface of the round rod 32. By setting the anti-blocking device 3, after the polyester fiber raw material is put into the feed hopper 8, the second motor 31 can be started to drive the round shaft 25 and the blades 33 to rotate inside the feed hopper 8, so that the internal outlet of the feed hopper 8 is always in an active state, avoiding the accumulation and jamming of the polyester fiber raw material, thereby avoiding blockage. At the same time, controlling the rotation speed of the second motor 31 can also control the feeding speed of the polyester fiber, which is conducive to improving the impurity removal efficiency of the impurity removal screening machine 1 and is convenient to use. A protective cover 34 is fixedly connected to one side of the feed hopper 8, and the second motor 31 is located inside the protective cover 34. By setting up a protective cover 34, the outer surface of the second motor 31 can be protected, making it less susceptible to impact during use or transportation and preventing damage.

[0033] Working principle: When using the impurity removal screening machine 1 to remove impurities from polyester fiber raw materials, the polyester fiber raw materials are usually placed directly into the feed hopper 8, then enter the impurity removal screening machine 1 and fall onto the filter screen 4. Simultaneously, the air pump 22 and the first motor 24 can be started. The first motor 24 drives the circular shaft 25 and the stirring rod 26 to rotate on top of the filter screen 4, causing the second circular ring plate 234 to slide on the two first circular ring plates 233, and driving the bevel gear 231 to move in a circular motion. At the same time, the bevel gear 231 meshes and rotates on the bevel gear ring block 232, causing the stirring rod 26 to rotate, thus lifting the polyester fiber raw materials filtered on the filter screen 4. This agitates the polyester fiber raw materials falling onto the filter screen 4. The mixing process allows the polyester fiber raw material to fully contact the filter screen 4, accelerating the efficiency of the filter screen 4 in removing impurities. Simultaneously, when the air pump 22 draws external air into the air jet frame 21 and blows it onto the filter screen 4, the stirring rod 26 pushes the air blown out by the air jet frame 21 to fully contact the polyester fiber raw material, blowing away the smaller and lighter impurities mixed in with it. These impurities are then blown out through the second drain pipe 210, performing a secondary thorough impurity removal and screening operation on the polyester fiber, thus improving the efficiency of impurity removal and screening. After the large particles of impurities are cleaned and filtered by the filter screen 4, the filtered and impurity-removed polyester fiber will be discharged from the discharge pipe 6, while the impurities filtered off the filter screen 4 will be discharged from the first drain pipe 5, achieving the effect of impurity removal and screening.

[0034] After the polyester fiber raw material is placed into the feed hopper 8, the second motor 31 can be started to drive the round shaft 25 and the blades 33 to rotate inside the feed hopper 8, so that the internal outlet of the feed hopper 8 is always in an active state, avoiding the accumulation and jamming of the polyester fiber raw material, thus avoiding blockage. At the same time, controlling the rotation speed of the second motor 31 can also control the feeding speed of the polyester fiber, which can improve the impurity removal efficiency of the impurity removal screening machine 1 and make it convenient to use.
