Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical fiber, and specifically relates to a connector device for reducing dust during chemical fiber vacuum drum feeding. Background Technology
[0002] The chemical fiber vacuum drum is a key post-processing equipment used in the production of chemical fibers (referred to as "chemical fibers"), mainly used for drying or heat-setting fibers.
[0003] The structure of a chemical fiber vacuum drum includes a drum body, which is a large, horizontally or slightly tilted, slowly rotating drum-shaped container. This drum is usually made of corrosion-resistant materials such as stainless steel. The chemical fiber vacuum drum is equipped with a vacuum pump system to establish and maintain a certain vacuum (negative pressure) inside the drum. The drum is usually equipped with a heating jacket or built-in heating tubes to provide heat to the drum wall; sometimes, heating elements are also installed inside the drum. During feeding, a feed pipe is connected to the feed port on the side wall of the drum, and the chemical fiber raw material is then pumped into the drum. On-site observation revealed a problem: because the gas inside the drum cannot be discharged in time at the connection between the feed pipe and the drum during the feeding process, dust is sprayed out from the feed port. Due to the high dust levels in the workshop, the environment is poor, and the workers face heavy workloads in cleaning, making it difficult to maintain a clean environment. Utility Model Content
[0004] The purpose of this invention is to provide a connector device for reducing dust during the feeding of chemical fiber vacuum drums. By installing a filter screen on the connector, the air permeability of the drum is ensured, and a large amount of dust is prevented from being sprayed out from the drum's feeding port, thus greatly optimizing the on-site environment.
[0005] The purpose of this utility model is achieved as follows: A connector device for reducing dust during the feeding of chemical fiber vacuum drum includes an inner cylinder and an outer cylinder arranged coaxially. Several reinforcing rods are radially arranged between the inner cylinder and the outer cylinder. An annular outer limiting plate is provided on the outer circumference of the outer cylinder. At least two circumferentially spaced mounting ears are provided on the outer limiting plate. One end of the inner cylinder is integrally connected to an inner ring body. An outer ring body is coaxially arranged corresponding to the inner ring body. Several radially evenly distributed connecting rods are provided between the outer ring body and the inner ring body. A filter screen is provided between any two circumferentially adjacent connecting rods between the outer ring body and the inner ring body. The flange edge of the outer ring body and the end of the outer cylinder body is fixed by several circumferentially evenly distributed fasteners. The other end of the inner ring body is connected to a feed conduit.
[0006] This invention relates to a feed inlet for connecting a rotating drum. The outer cylinder is gripped by a handle and inserted into the feed inlet on the side of the drum. The outer circumference of the outer cylinder matches the inner diameter of the feed inlet, ensuring the outer limiting plate contacts the side of the drum. The drum exterior has connecting holes corresponding to mounting ears, which are then secured to the connecting holes with fasteners. Material is fed into the drum through the feed guide and inner cylinder. A filter screen between the outer and inner rings increases air permeability, preventing large amounts of dust from being ejected from the drum's feed inlet. This improvement significantly optimizes the working environment. The filter screen has micropores, further preventing dust leakage. Compared to existing technologies, the advantages of this invention are: by installing a filter screen on the connector, the drum's air permeability is ensured, preventing large amounts of dust from being ejected from the drum's feed inlet, thus significantly optimizing the working environment.
[0007] As a further improvement of this utility model, at least two rings of reinforcing rods are provided between the inner cylinder and the outer cylinder, each ring of reinforcing rods including four reinforcing rods evenly distributed circumferentially. The reinforcing rods ensure that the inner cylinder and the outer cylinder are connected as a whole.
[0008] As a further improvement of this utility model, a mounting groove is provided on the mounting ear. The fastening bolt passes through the mounting groove and is connected and fixed to the rotating drum.
[0009] As a further improvement of this utility model, the other end of the inner cylinder extends out of the outer cylinder. Two U-shaped grip handles, spaced 180° apart circumferentially, are provided on the outer circumference of the outer cylinder. These grip handles are fixed to the outer cylinder via two connecting parts. The grip handles are located behind the outer limiting plate, and are offset circumferentially from the mounting ears of the outer cylinder. By gripping the outer cylinder of the connector with the grip handles, it is convenient to install the connector onto the drum.
[0010] As a further improvement of this utility model, four connecting rods are provided.
[0011] As a further improvement of this utility model, the feed conduit is a flexible hose. A steel wire hose is used, with a high-strength steel wire installed inside the hose, through which the material enters the rotating drum. Attached Figure Description

At least two rings of reinforcing rods 3 are provided between the inner cylinder 1 and the outer cylinder 2, each ring including four reinforcing rods 3 evenly distributed circumferentially. The reinforcing rods 3 ensure that the inner cylinder 1 and the outer cylinder 2 are connected as a single unit. An annular outer limiting plate 4 is provided on the outer circumference of the outer cylinder 2. At least two circumferentially spaced mounting ears 5 are provided on the outer limiting plate 4, and mounting grooves 12 are provided on the mounting ears 5. Fastening screws... The bolt passes through the mounting groove 12 and is connected and fixed to the drum; one end of the inner cylinder 1 is connected to an inner ring body 6 as a whole, and an outer ring body 7 is coaxially arranged corresponding to the inner ring body 6. Several radial connecting rods 8 are evenly distributed in the circumferential direction between the outer ring body 7 and the inner ring body 6, and four connecting rods 8 are provided; a filter screen 9 is provided between any two adjacent connecting rods 8 in the circumferential direction between the outer ring body 7 and the inner ring body 6. The outer ring body 7 and the flange edge 2a at the end of the outer cylinder 2 are fixed by several fasteners 10 evenly distributed in the circumferential direction. The other end of the inner ring body 6 is connected to a feed guide tube 11.
[0019] The other end of the inner cylinder 1 extends out of the outer cylinder 2. Two U-shaped grip handles 13, spaced 180° apart circumferentially, are provided on the outer circumference of the outer cylinder 2. The grip handles 13 are fixed to the outer cylinder 2 via two connecting parts 13a.

The outer circumference of the outer cylinder 2 matches the inner diameter of the feeding port, allowing the outer limiting plate 4 to contact the side of the rotating drum. The outside of the rotating drum has connecting holes corresponding to the mounting ears 5, which are fixed to the connecting holes using fasteners 10. Material can be fed into the rotating drum through the feed guide 11 and the inner cylinder 1. The filter screen 9 between the outer ring 7 and the inner ring 6 increases air permeability, preventing a large amount of dust from spraying out of the rotating drum's feeding port. This improvement significantly optimizes the on-site environment. The filter screen 9 has micropores, further preventing dust leakage. The advantages of this utility model are: by installing the filter screen 9 on the connector, the air permeability of the rotating drum is ensured, preventing a large amount of dust from spraying out of the rotating drum's feeding port, thus significantly optimizing the on-site environment.
