Description

Technical Field

[0001] The utility model relates to the field of mixers, in particular to a cantilever conical double-helix mixer. Background Art

[0002] The spiral mixer is a commonly used mixing equipment, which uses mechanical force and gravity to evenly mix two or more materials. There are many types of spiral mixers, which can be divided into four categories according to different working principles and structural characteristics: gas and low-viscosity liquid mixers, medium-high-viscosity liquid and paste mixers, and powdered and granular solid material mixers.

[0003] After searching, the application number is "202320251190.9", which provides a cantilevered conical double-helix mixer. At the same time, the scraper 8 moves along the inner wall of the conical cylinder 1, which can not only quickly mix the material in the conical cylinder 1, but also scrape off the material adhering to the inner wall, and with the cooperation of multiple paddles 81, it can also realize auxiliary stirring and mixing operations. After the mixing is completed, the sealing plate 11 is removed by the handle rod, and the material in the conical cylinder 1 can be quickly discharged from the conical cylinder 1 under the action of gravity.

[0004] The above-mentioned method cleans the residual material leaking on the inner wall of the mixer by rotating the scraper, and discharges the material by removing the bottom sealing plate. However, when mixing medium and high viscosity liquids, the liquid will not only remain on the inner wall of the mixer, but also the inner wall of the mixer's discharge pipe will have residual medium and high viscosity liquid. If these materials are not cleaned for a long time, the discharge of the discharge pipe will be easily hindered. Utility Model Content
