Abstract
Description
Technical Field
[0001] This utility model relates to the field of polypropylene production technology, specifically to a purification device for polypropylene. Background Technology
[0002] Polypropylene, abbreviated as PP, is a polymer formed by the addition polymerization of propylene. It is a white, waxy material that is transparent and granular in appearance. It has chemical resistance, heat resistance, electrical insulation, high mechanical strength, and good wear resistance. Polypropylene granules are often used for die extrusion molding. However, existing polypropylene granules contain impurities. If they are used directly for die extrusion molding, it will reduce the quality of the extrusion mold. Therefore, it is necessary to screen out impurities from polypropylene granules.
[0003] According to the search, a patent announcement number CN220741798U for a polypropylene production impurity screening device was published in China on April 9, 2024. It is roughly described as including a screening box, a vibrating motor and a feed pipe on the screening box, a screen for blocking impurities inside the screening box, a storage box for impurities, a blower and a cylinder on the screening box, a filter screen in the side wall of the screening box, an air blowing pipe connected to the blower, an impurity inlet on the storage box, and a discharge pipe on the storage box.
[0004] Although the above-mentioned existing technical solutions can remove light powder impurities and iron filings, the device directly blows away light powder impurities from the raw material during feeding, causing the raw material to accumulate and resulting in poor impurity removal effect. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a purification device for polypropylene, which solves the problem mentioned in the background technology that directly blowing away light powder impurities from the raw material during feeding causes the raw material to accumulate, resulting in poor purification effect.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a polypropylene impurity removal device, comprising a processing box and a base plate. Four evenly distributed support legs are fixedly connected to the bottom of the processing box, and the bottom ends of the four support legs are fixedly connected to the base plate. A storage box is fixedly connected to the top of the base plate, and the storage box has a discharge port with a sealing plate. The bottom of the processing box has a discharge port. A limiting frame is provided on the outer wall of the processing box, and an arc-shaped sealing plate that mates with the discharge port is slidably connected inside the limiting frame. The top of the processing box has a feed port, and a vibration motor is installed at the top of the processing box. Two cooperating inclined guide plates are fixedly connected inside the processing box. Two impurity removal ports that mate with the inclined guide plates are opened at one end of the processing box. Two impurity removal pipes that mate with the two impurity removal ports are fixedly connected to the outer wall of the processing box, and one end of each impurity removal pipe is connected to the storage box. Two fans that mate with the impurity removal ports are installed on the outer wall of the processing box.
[0009] By adopting the above technical solution, the vibration motor is started to drive the processing box to vibrate. The raw material is put into the processing box from the feed port, so that the raw material moves along the upper inclined guide plate, which makes it easier for light impurities in the raw material to vibrate to the upper edge of the raw material, thereby separating the light impurities from the raw material. At this time, two fans are started. When the raw material falls from the upper inclined guide plate, the fans blow the light impurities, so that the light impurities enter the impurity storage box through the impurity removal port and impurity removal pipe. Then the raw material falls onto the lower inclined guide plate. The above process is repeated to further improve the blowing effect of light impurities. After the light impurities are blown away, the raw material falls to the bottom of the processing box, thereby achieving the purpose of improving the impurity removal effect.
[0010] Optionally, a control shaft is rotatably connected inside the processing box. The control shaft is equipped with four electric transmission rods, and two electromagnets are attached to the inner side wall of the processing box on the four electric transmission rods. A servo motor connected to the control shaft is installed on the outer wall of the processing box, and a socket connected to the control shaft is installed on the outer wall of the processing box.
[0011] By adopting the above technical solution, when light impurities fall to the bottom of the processing box, the servo motor is started to drive the control shaft, the electric rod and the electromagnet to rotate, so that the electromagnet repeatedly stirs the raw material, thereby improving the effect of adsorbing and removing metal impurities in the raw material.
[0012] Optionally, a material gathering and discharging component is fixedly connected to the bottom of the processing box.
[0013] By adopting the above technical solution, the material gathering and discharging component is used to gather the discharged material when the equipment discharges material, reduce the discharge port, and facilitate the collection of the discharged material.
[0014] Optionally, both of the impurity removal ports are equipped with filters.
[0015] By adopting the above technical solution, when blowing away light impurities, the filter screen is used to filter the raw materials, avoiding the accidental removal of normal raw materials.
[0016] Optionally, the storage box is provided with a transparent observation window.
[0017] By adopting the above technical solution, the transparent observation window is used to facilitate personnel to observe the inside of the storage box, so that impurities can be discharged in time when the storage box is about to be full, avoiding affecting the equipment's ability to remove impurities.
[0018] (III) Beneficial Effects
[0019] In summary, this utility model has at least one of the following beneficial technical effects:
[0020] This polypropylene impurity removal device works by starting a vibration motor to vibrate the processing box. Raw materials are fed into the box through the inlet, moving along an upper inclined guide plate. This vibrates light impurities to the upper edge of the material, separating them from the raw material. Two blowers are then activated. As the raw material falls from the upper inclined guide plate, the blowers agitate the light impurities, causing them to pass through the impurity removal port and pipe into a storage tank. The raw material then falls onto the lower inclined guide plate. This process is repeated to further improve the removal of light impurities. After the light impurities are removed, the raw material falls to the bottom of the processing box, achieving the goal of improved impurity removal. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] The present invention will be further described in detail below with reference to the accompanying drawings.
[0029] Reference Figures 1-5 A polypropylene impurity removal device includes a processing box 1 and a base plate 2. Four evenly distributed support legs 3 are fixedly connected to the bottom end of the processing box 1, with their bottom ends fixedly connected to the base plate 2. A storage box 4 is fixedly connected to the top end of the base plate 2, and the storage box 4 has a discharge port with a sealing plate 5. The bottom end of the processing box 1 has a discharge port. A limiting frame 6 is provided on the outer wall of the processing box 1, and an arc-shaped sealing plate 75 that mates with the discharge port is slidably connected inside the limiting frame 6. The top end of the processing box 1 has a feed inlet 8, and a vibration motor 9 is installed at the top end of the processing box 1. Two cooperating inclined guide plates 10 are fixedly connected inside the processing box 1. Two impurity removal ports that mate with the inclined guide plates 10 are opened at one end of the processing box 1. Two impurity removal pipes 1, each mate with one of the two impurity removal ports, are fixedly connected to the outer wall of the processing box 1. 1. One end of each of the two impurity removal pipes 11 is connected to the impurity storage box 4. Two blowers 20, which are matched with the impurity removal ports, are installed on the outer wall of the processing box 1. The vibration motor 9 is started to drive the processing box 1 to vibrate. The raw material is put into the processing box 1 through the feed port 8, so that the raw material moves along the upper inclined guide plate 10, which makes it easier for the light impurities in the raw material to vibrate to the upper edge of the raw material, so as to separate the light impurities from the raw material. At this time, the two blowers 20 are started. When the raw material falls from the upper inclined guide plate 10, the blowers 20 blow the light impurities, so that the light impurities enter the impurity storage box 4 through the impurity removal port and the impurity removal pipe 11, and then the raw material falls onto the lower inclined guide plate 10. The above process is repeated to further improve the blowing effect of light impurities. After the light impurities are blown away, the raw material falls to the bottom of the processing box 1, thus achieving the purpose of improving the impurity removal effect.
[0030] Reference Figure 3 The processing box 1 is rotatably connected to a control shaft 12. The control shaft 12 is equipped with four electric rods 13. Two electromagnets 14 are attached to the inner wall of the processing box 1 on the four electric rods 13. A servo motor 15 connected to the control shaft 12 is installed on the outer wall of the processing box 1. A socket 16 connected to the control shaft 12 is also installed on the outer wall of the processing box 1. When light impurities fall to the bottom of the processing box 1, the servo motor 15 is started to drive the control shaft 12, electric rods 13 and electromagnets 14 to rotate. This causes the electromagnets 14 to repeatedly stir the raw materials, thereby improving the adsorption and removal effect of metal impurities in the raw materials.
[0031] Reference Figure 2 and Figure 3 The bottom of the processing box 1 is fixedly connected to a material gathering and discharging component 17. The material gathering and discharging component 17 is used to gather the discharged material when the equipment discharges the material, reduce the discharge port, and facilitate the collection of the discharged material.
[0032] Reference Figure 3 and Figure 4 Both impurity removal ports are equipped with filter screens 18. When blowing away light impurities, the filter screens 18 are used to filter the raw materials to avoid the accidental removal of normal raw materials.
[0033] Reference Figure 1 The storage box 4 is equipped with a transparent observation window 19, which is used to facilitate personnel to observe the inside of the storage box 4 so that impurities can be discharged in time when the storage box 4 is about to be full, so as to avoid affecting the equipment to remove impurities.
[0034] In summary, the working principle and process of this polypropylene impurity removal device are as follows: First, the vibration motor 9 is started to vibrate the processing box 1. The raw material is then placed into the processing box 1 through the feed inlet 8, causing it to move along the upper inclined guide plate 10. This allows light impurities in the raw material to vibrate to the upper edge, separating them from the raw material. Then, two blowers 20 are activated. As the raw material falls from the upper inclined guide plate 10, the blowers 20 blow away the light impurities, causing them to pass through the impurity removal port and pipe 11 into the impurity storage box 4. The raw material then falls onto the lower inclined guide plate 10. This process is repeated to further improve the removal of light impurities. After the light impurities are removed, the raw material falls to the bottom of the processing box 1, thus improving the impurity removal efficiency. The purpose of this system is to activate the servo motor 15 to drive the control shaft 12, the electric transmission rod 13, and the electromagnet 14 to rotate after the light impurities fall to the bottom of the processing box 1. This causes the electromagnet 14 to repeatedly agitate the raw materials, thereby improving the adsorption and removal effect of metal impurities in the raw materials. The material gathering and discharging component 17 is used to gather the discharged materials when the equipment discharges materials, reducing the discharge port and facilitating the collection of discharged materials. When blowing away light impurities, the filter screen 18 is used to filter the raw materials to avoid the accidental discharge of normal raw materials. The transparent observation window 19 is used to facilitate personnel to observe the inside of the storage box 4, so that when the storage box 4 is about to be full, the impurities can be discharged in time to avoid affecting the equipment's removal of impurities.
[0035] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
