Embodiment approach
[0025] As an embodiment, the first blanking assembly includes a first blanking pipe 1, a compensation pipe 2, a blanking flange 3, a flexible pipe 4, and a sliding plate 5 connected vertically in sequence, and the flexible pipe 4 is set to be able to telescopic to adjust the axial distance of the sliding plate 5 relative to the blanking flange 3 . Among them, in order to ensure the long-term stable and reliable operation of the inlet material receiving equipment, the compensation pipe 2 is used to solve the problem that the centerlines of the first feeding pipe 1 and the inlet of the vibrating screen 9 do not coincide. Specifically, the compensation pipe 2 is composed of an upper flange, a lower flange, and a middle section. The upper flange and the first blanking pipe 1 are connected by bolts, and the lower flange and the blanking flange 3 are connected by bolts. In order to ensure that the compensation pipe 2. There is no material accumulation, and the middle section is extr...

Abstract
The invention relates to the technical field of vibrating screening equipment, and discloses a vibrating screen inlet material receiving device and polyethylene production equipment. The vibrating screen inlet material receiving device comprises a first discharging assembly and a second discharging assembly which are sequentially arranged in the vertical direction, abrasion-resistant sliding rings (6) are arranged on the opposite end faces of the first discharging assembly and the second discharging assembly, and a vibrating screen (9) is connected to an outlet of the second discharging assembly. The second discharging assembly can be driven by a driving machine of the vibrating screen to do circumferential reciprocating motion relative to the first discharging assembly along with the vibrating screen, so that materials entering from the first discharging assembly can fall to the vibrating screen through the second discharging assembly and are screened out through the vibrating screen. The material receiving device is simple in structure, few in parts, reliable in connection, low in maintenance cost and high in reliability, only the wear-resistant slip ring needs to be replaced, the wear-resistant slip ring can be replaced on line under the condition that the vibrating screen does not stop, load fluctuation is reduced, and economic benefits are guaranteed.
Description
technical field [0001] The invention relates to the technical field of vibrating screening equipment, in particular to a vibrating screen inlet material receiving device. On this basis, it also relates to a polyethylene production equipment. Background technique [0002] There is a quantity index of "size and particle" in the finished product index of polyethylene granules. The polyethylene granules formed by the granulator must pass through the granule vibrating sieve, and the oversized and undersized granules will be screened out through the vibrating sieve, and the granules that meet the index range will be screened out. sent to downstream equipment. The particle vibrating screen is mainly composed of a driving machine head, a base, a screen, and a screen box. The machine head drives the screen box to perform reciprocating rotary motion. Polyethylene particles enter the vibrating screen through the inlet feeding device. The two-layer screen will be too large or The part...
