Description

Technical Field

[0001] The utility model relates to the technical field of nylon 6 chip dust removal, in particular to a nylon 6 chip dust collector. Background Art

[0002] Nylon 6 chips refer to thin slices or small pieces obtained by cutting nylon 6 materials into certain sizes and shapes. Nylon 6 chips are often used to manufacture nylon products, such as nylon sheets, nylon pipes, nylon processed parts, etc. Nylon 6 chips have good mechanical strength, wear resistance and corrosion resistance, as well as high melting point and heat deformation temperature, which makes nylon 6 chips widely used in various application fields, such as automotive parts, electronic equipment, mechanical parts, chemical containers, etc.

[0003] Nylon 6 chip dust removal refers to the process of removing dust and impurities from nylon 6 chips. Since nylon 6 chips are often used to manufacture high-demand products such as electronic equipment and automotive parts, dust removal can improve their quality and quality stability.

[0004] The prior art has the following deficiencies: conventional nylon 6 chip dust collectors usually use two methods: mechanical dust removal and electrostatic dust removal. Mechanical dust removal separates dust and impurities from nylon 6 chips through a screen, but since nylon 6 chips are mostly in the form of thin sheets, they are easy to cover the screen holes when passing through the screen, resulting in the inability to screen out dust. Moreover, when using mechanical screens such as rotary screens and vibrating screens for filtering, long-term collisions can easily damage and break the nylon 6 chips, generating more broken dust. Electrostatic dust removal absorbs dust through the electrostatic adsorption effect. However, when nylon 6 chips contact the charge collection plate with dust, due to the small size and light weight of nylon 6 chips, a large number of nylon 6 chips are also easily electrostatically adsorbed by the charge collection plate, which not only causes the loss of nylon 6 chips, but also fails to completely separate dust from nylon 6 chips. Moreover, after the charge collection plate collects a certain amount of dust, its electrostatic adsorption capacity decreases. If the dust cannot be cleaned in time, the dust removal efficiency of the electrostatic dust removal will be greatly reduced.

[0005] Therefore, it is necessary to invent a nylon 6 chip dust collector. Utility Model Content

Since the charge adsorption plate 26 and the conveyor belt 13 maintain a certain distance, the nylon 6 slices with a larger mass will not The negatively charged dust impurities will be adsorbed, and the negatively charged dust impurities will be adsorbed on the surface of the charge adsorption plate 26. Then, the transmission roller 23 is started to drive the angle wheel 25 to rotate. The rotation of the angle wheel 25 drives the connecting rotating bar 27 and the charge adsorption plate 26 to circulate to the eccentric wheel 30. The motor 32 is started to drive the rotating rod 31 to drive the eccentric wheel 30 to rotate.
