Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene composite material production, in particular to a feeding device for polyethylene composite materials. Background Technique

[0002] Polyethylene composite materials are the general term for various functional materials formed by compounding polyethylene as the base material with other materials. They have the characteristics of high strength, good toughness, good abrasion resistance, etc. In the production process of polyethylene composite materials, reaction raw materials need to be put into a reaction kettle, which requires the use of a feeding device.

[0003] In the prior art, the publication number CN209490799U is an authorized patent, which discloses a feeding device for a reaction kettle used in composite material processing and production. When the existing reaction kettle feeds raw materials into the kettle body, impurities are often contained, resulting in phenomena such as uneven reaction and overreaction, directly affecting the product quality. Moreover, the size of the discharge port is fixed and cannot be docked with reaction kettles of different sizes, so the practicability is poor. The utility model relates to a feeding device for a reaction kettle used in composite material processing and production, wherein: a funnel-shaped feeding box is fixed on the top of the feeding box and communicates with the inside of the feeding box; a motor is fixed on one side of the support plate; a cleaning port is arranged on one side of the feeding box; the other end of the support column is provided with a roller; the top of the first discharge pipe is fixedly connected to the bottom of the feeding box; the second discharge pipe is fixed inside the first discharge pipe by being threadedly connected to the first discharge pipe; the third discharge pipe is fixed inside the second discharge pipe by being threadedly connected to the second discharge pipe. This device can effectively filter impurities and is easy to clean, and can feed different sizes of reaction kettles, with strong practicability.

[0004] When the above technical solution is used, there are still the following deficiencies: the time for the raw materials to pass through the filter plate in the above device is relatively fast, resulting in partial accumulation of some raw materials and insufficient screening, so that the screening of impurities in the raw materials is not thorough and the screening effect is poor. In view of this, we propose a feeding device for polyethylene composite materials. Content of the Utility Model
