Description

Technical Field

[0001] This application relates to the field of polypropylene particle cleaning technology, and in particular to a polypropylene particle cleaning device. Background Technology

[0002] Polypropylene (PP) is a thermoplastic with well-balanced properties and extremely wide applications. Its core advantages include lightweight, good chemical resistance, low cost, and ease of processing, making it irreplaceable in packaging, automotive, consumer goods, medical, and industrial fields. During the processing and molding of PP materials, it is necessary to remove impurities (dust) mixed within the PP, typically through washing. For example, patent CN202322913443.7 discloses a PP particle washing device that removes metal from PP particles using magnetic attraction and removes small particulate impurities through filtration. However, this washing process requires multiple transfers of the PP particles, necessitating significant manpower and resources. Summary of the Invention

[0003] The purpose of this application is to provide a polypropylene particle cleaning device to solve the technical problem that "the polypropylene needs to be transferred multiple times during the cleaning process, requiring more manpower or material resources."

[0004] The polypropylene granule cleaning device provided in this application adopts the following technical solution: A polypropylene granule cleaning device includes an air inlet pipe, a suction fan installed on the suction bin, a suction pipe provided on the side of the suction bin, a discharge port provided at the lower end of the suction bin, an air inlet pipe provided above the discharge port, a conical adsorption plate provided inside the suction bin, a magnetic adsorption block provided on the conical adsorption plate, a material blocking protrusion provided on the upper side of the conical adsorption plate, and a discharge channel provided between the conical adsorption plate and the suction bin; the air inlet pipe is used to input gas into the air inlet pipe to agitate the polypropylene granules.

[0005] Optionally, a suction switch is installed on the suction pipe, a discharge switch is installed on the discharge port, and an air inlet switch is installed on the air inlet pipe.

[0006] Optionally, a support ring is installed on the inner wall of the suction chamber, and the conical suction plate is detachably installed with respect to the support ring.

[0007] Optionally, the suction bin includes a bin body and a bin cover, the bin body and the bin cover being detachably connected; the suction fan is installed on the bin cover.

[0008] Optionally, the suction pipe extends from the outer wall of the suction bin to the middle position of the conical suction plate.

[0009] Optionally, the upper side of the conical adsorption plate is provided with a groove for storing high-density impurities.

[0010] In summary, this application includes at least one of the following beneficial technical effects: 1. During the feeding process of polypropylene granules, the suction fan creates negative pressure in the suction hopper, and the polypropylene granules are sucked into the suction hopper through the suction pipe. When the polypropylene granules enter the suction hopper with the airflow, the airflow slows down, and the polypropylene granules fall downward under their own gravity. The low-density dust continues to be discharged from the blower with the airflow. 2. When the polypropylene particles reach the position of the conical adsorption plate, the polypropylene particles diffuse outward along the conical adsorption plate, so that the impurities with low density are further dispersed with the polypropylene particles and discharged with the airflow. The metal powder is adsorbed on the conical adsorption plate under the action of the magnetic block. 3. When the polypropylene particles reach the lower side of the conical adsorption plate, close the suction pipe 3 and open the air inlet pipe. Gas enters from the air inlet pipe, and the airflow agitates the polypropylene particles, further separating the dust from the polypropylene particles. 4. After the polypropylene granules are cleaned, they are fed into the polypropylene processing equipment through the feeding channel for processing, thus eliminating the need for manual transfer and saving manpower.

[0012] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0013] Reference Figure 1A polypropylene granule cleaning device includes an air inlet pipe 5, a suction fan 2 installed on a suction chamber 1, a suction pipe 3 provided on the side of the suction chamber 1, a discharge port 4 provided at the lower end of the suction chamber 1, an air inlet pipe 5 provided on the upper side of the discharge port 4, a conical adsorption plate 6 provided inside the suction chamber 1, a magnetic adsorption block 7 provided on the conical adsorption plate 6, a material blocking protrusion 61 provided on the upper side of the conical adsorption plate 6, and a discharge channel 8 provided between the conical adsorption plate 6 and the suction chamber 1; the air inlet pipe 5 is used to input gas into the air inlet pipe 5 to agitate the polypropylene granules.

[0014] During the feeding process of polypropylene granules, the suction fan 2 creates negative pressure in the suction chamber 1, and the polypropylene granules are sucked into the suction chamber 1 through the suction pipe 3. When the polypropylene granules enter the suction chamber 1 with the airflow, the airflow slows down, and the polypropylene granules fall downwards under their own gravity. The low-density dust continues to be discharged from the suction fan 2 with the airflow. When the polypropylene particles reach the position of the conical adsorption plate 6, the polypropylene particles diffuse outward along the conical adsorption plate 6, so that the impurities with low density are further dispersed with the polypropylene particles and discharged with the airflow. The metal powder is adsorbed on the conical adsorption plate under the action of the magnetic block 7. When the polypropylene particles reach the lower side of the conical adsorption plate 6, the suction pipe 3 is closed and the air inlet pipe 5 is opened. The gas enters from the air inlet pipe 5 (in order to prevent dust from re-entering, a dust removal device can be installed at the end of the air inlet pipe 5). The airflow agitates the polypropylene particles, further separating the dust from the polypropylene particles. After the polypropylene granules are cleaned, they are fed into the polypropylene processing equipment through outlet 4 for processing, thus eliminating the need for manual transfer and saving manpower.

[0015] Optionally, a suction switch 31 is installed on the suction pipe 3, a discharge switch 41 is provided on the discharge port 4, and an air inlet switch 51 is provided on the air inlet pipe 5.

[0016] When the polypropylene particles reach the lower side of the conical adsorption plate 6, the suction pipe 3 is closed by the suction switch 31 and the air inlet switch 51 is opened by the air inlet pipe 5. Gas enters from the air inlet pipe 5 (in order to prevent dust from re-entering, a dust removal device can be installed at the end of the air inlet pipe 5). The airflow agitates the polypropylene particles, further separating the dust from the polypropylene particles. Optionally, a support ring 32 is installed on the inner wall of the suction chamber 1, and the conical adsorption plate 6 is detachably installed with the support ring 32; the conical adsorption plate 6 can be detachably connected with the support ring 32, and the conical adsorption plate 6 can be removed to clean the adsorbed metal.

[0017] Optionally, the suction chamber 1 includes a chamber body 11 and a chamber cover 12, the chamber body 11 and the chamber cover 12 are detachably connected; the suction fan 2 is installed on the chamber cover 12, which can separate the chamber cover 12 from the chamber body 11 and remove the conical suction plate 6 (a lifting ring is installed on the conical suction plate 6).

[0018] Optionally, the suction pipe 3 extends from the outer wall of the suction chamber 1 to the middle position of the conical adsorption plate 6; when the polypropylene particles are discharged from the suction pipe 3, they can diffuse from the center of the conical adsorption plate 6 to the surrounding area, effectively preventing the polypropylene particles from accumulating on one side and affecting the adsorption effect of the magnetic block 7.

[0019] Optionally, a groove 62 is provided on the upper side of the conical adsorption plate 6. The groove 62 is used to store high-density impurities. The high-density impurities slide down the upper side of the conical adsorption plate 6 under their own gravity. After reaching the material blocking protrusion 61, they stop moving downward and accumulate in the groove 62, preventing the high-density impurities from falling further. The airflow is blocked by the conical adsorption plate 6, and the side airflow is blocked by the blocking material protrusion 61. There is no strong airflow on the upper side of the conical adsorption plate 6, so that dense impurities will not rise with the airflow and will not further diffuse into the groove 62. When polypropylene particles and denser impurities fall onto the conical adsorption plate 6, the inherent vibration of the equipment causes the denser impurities to move downwards and settle in the groove 62.

[0020] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
