Description

Technical Field

[0001] The utility model relates to the field of vacuum feeding devices, in particular to a vacuum particle feeding device. Background Art

[0002] Polyethylene is a thermoplastic resin obtained by polymerization of ethylene monomers. The finished products are mostly in granular form. In the process of conveying polyethylene particle materials, a vacuum particle conveyor is usually used for conveying. The pressure difference between the vacuum and the ambient space is used to form a gas flow in the pipeline, drive the movement of the material, and thus complete the material transportation. This scheme specifically relates to a vacuum particle conveying device; the existing polyethylene particle materials contain a certain amount of dust, and the existing vacuum particle conveying device can only convey the polyethylene particle materials, but the dust attached to the surface of the polyethylene particles cannot be desorbed and collected during the conveying process. The presence of dust will affect the subsequent use of the polyethylene particle materials. At the same time, the polyethylene particle materials are in direct contact with the filter during the conveying process. The polyethylene particle materials are easily attached to the outer surface of the filter in large quantities, causing the outer surface of the filter to be blocked, and the inside of the vacuum material tank loses negative pressure.

After negative pressure is formed inside the vacuum tank, the polyethylene particle material is sucked into the vacuum tank and attached to the outer surface of the filter ball.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-Figure 4 As shown, a vacuum particle feeding device comprises a vacuum material tank 1, a tank cover 2 is installed on the top of the vacuum material tank 1, an air pipe 3 is fixedly installed through the top of the tank cover 2, a recoil structure 4 is fixedly installed on one side of the air pipe 3, a vacuum generator 5 is fixedly installed through the top of the tank cover 2 on one side, a transfer tube 7 is fixedly installed through the upper end of one side of the vacuum material tank 1, a dust collecting tank 9 is installed on the bottom end of the transfer tube 7, a fan 8 is fixedly installed on one side of the transfer tube 7, and an anti-blocking component 6 is installed inside the vacuum material tank 1 and through both sides of the tank body of the vacuum material tank 1.

[0020] The anti-blocking component 6 includes a filter ball 601, and couplings 603 are installed on both sides of the filter ball 601. A motor 602 is installed on one side of one coupling 603. The anti-blocking component 6 is arranged to prevent a large amount of polyethylene particles from being adsorbed on the surface of the filter 13, causing the outer surface of the filter 13 to be blocked due to the attachment of polyethylene particles.

[0021] The shaft of the filter ball 601 is movably connected to the coupling 603, the coupling 603 is fixedly connected to the vacuum tank 1, the output shaft of the motor 602 is fixedly connected to the shaft of the filter ball 601, the shell of the motor 602 is fixedly connected to the vacuum tank 1, the outer surface of the filter ball 601 is tangent to the inner wall of the vacuum tank 1, when the vacuum generator 5 is started, a negative pressure is formed inside the vacuum tank 1, and the polyethylene particles are adsorbed on the surface of the filter ball 601. After the motor 602 is started, it drives the filter ball 601 to rotate. During the rotation of the filter ball 601, the polyethylene particles are separated from the surface of the filter ball 601 by the obstruction of the inner wall of the vacuum tank 1, thereby preventing a large amount of polyethylene particles from adhering to the surface of the filter ball 601.

[0022] A feed pipe 10 is fixedly installed on one side of the vacuum tank 1 near the bottom, and a discharge pipe 11 is fixedly installed on the bottom of the vacuum tank 1. A suction hose is installed through the feed pipe 10. When the polyethylene particles enter the vacuum tank 1 through the feed pipe 10 and the suction hose, they are discharged from the vacuum particle conveying device through the discharge pipe 11.

[0023] A carrying ring 14 is fixedly installed on the inner wall of the vacuum tank 1 near the top, and a carrying plate 12 is provided on the inner circle of the carrying ring 14. A plurality of filters 13 are fixedly installed in the middle of the upper and lower ends of the carrying plate 12. The carrying ring 14 is used to limit the carrying plate 12. When the vacuum particle feeding device is running, the filter 13 filters the internal space of the vacuum tank 1 to prevent dust in the polyethylene particle material from being sucked into the vacuum generator 5.

[0024] The carrying plate 12 is sleeved with the carrying ring 14, and sealing rings are provided between the tank cover 2 and the vacuum tank 1, and between the carrying plate 12 and the carrying ring 14. The sealing rings are used to seal between the tank cover 2 and the vacuum tank 1, and between the carrying plate 12 and the carrying ring 14, to ensure that negative pressure is formed inside the vacuum tank 1 after the vacuum generator 5 is started.

[0025] It should be noted that the utility model is a vacuum particle feeding device. When in use, the vacuum particle feeding device is first installed on the bracket using the fixing feet at the front and rear ends of the vacuum tank 1, and then the suction hose is connected to the feed pipe 10. After the suction hose is aligned with the polyethylene particle material, the vacuum generator 5, the fan 8 and the motor 602 are started, and negative pressure is formed inside the vacuum tank 1. The polyethylene particle material is sucked into the vacuum tank 1 through the suction hose and the feed pipe 10 and adheres to the outer surface of the filter ball 601.

[0026] After the motor 602 is started, it drives the filter ball 601 to rotate. During the rotation of the filter ball 601, the polyethylene particle material is filtered. The polyethylene particle material attached to the surface of the filter ball 601 is blocked by the inner wall of the vacuum tank 1, and the polyethylene particle material is discharged through the discharge pipe 11. The dust in the polyethylene particle material passes through the filter ball 601 and is filtered by the filter 13. Part of it is attached to the outer surface of the filter 13 to prevent the dust from entering the vacuum generator 5 and causing blockage, and the other part is suspended above the filter ball 601.

[0027] After the fan 8 is started, the dust suspended inside the vacuum tank 1 is extracted through the transfer tube 7 and stored in the dust tank 9, so as to collect the dust in the polyethylene particle material. After the feeding is completed, the recoil structure 4 is started and the motor 602 is turned off. The airflow formed by the recoil structure 4 impacts the filter 13, so that the dust on the surface of the filter 13 is detached, and then the detached dust is adsorbed into the dust tank 9, and the polyethylene particle material attached to the surface of the filter ball 601 falls off.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
