Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a discharge door structure of a powerful mixer. Background Art

[0002] The inclined mixing test machine can be used as a formula exploration and formula optimization and upgrading equipment for various industrial material mixing and granulation formal products before production. Because the equipment has a high degree of automation, a small footprint, simple operation, a small amount of material input in a single batch, and high test efficiency, it can shorten the time from early demonstration to later production, and provide a basis for the selection of later production models and the design of other auxiliary machines; therefore, it is widely used in laboratories of major companies and scientific research institutions.

[0003] When the mixer is unloading, it is necessary to open the upper unloading cover and then pour out the material in the mixing barrel. When the mixer is working, the unloading cover needs to fit tightly with the mixing barrel and needs to be sealed to prevent the material powder from diffusing into the air and causing air pollution. Utility Model Content

[0004] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides a discharge door structure of a powerful mixer.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a discharge door structure of a high-power mixer, comprising a mixer body, a mixing cylinder movably installed on the upper part of the mixer body, a discharge cover sealably and movably installed on the upper part of the mixing cylinder, a mixing mechanism fixedly installed on the lower end of the discharge cover, an annular groove is arranged inside the discharge cover, a group of ventilation pipes are fixedly connected to the upper end of the annular groove, and a plurality of ventilation holes are arranged at the lower end of the annular groove.

[0006] Furthermore, a thrust bearing is provided at the lower end of the discharge cover, and a second wedge ring is fixedly mounted at the lower end of the thrust bearing.

[0007] Furthermore, a first wedge-shaped ring is fixedly mounted on the upper end of the mixing cylinder, and the upper end of the first wedge-shaped ring is mounted in contact with the second wedge-shaped ring.

[0008] Furthermore, a circular ring is fixedly mounted on the inner upper end of the mixing cylinder, and a slope is arranged on the outer upper end of the circular ring, and the slope is located at the lower end of the vent hole.

[0009] Furthermore, a plurality of groups of air guide plates are provided at the lower end of the discharge cover, and the air guide plates are located between each group of vent holes.

[0010] Furthermore, a pressure relief hole is provided inside the discharge cover, the lower end of the pressure relief hole is connected to the inside of the mixing cylinder, and the upper end of the pressure relief hole is connected to the outside.

[0011] The beneficial effects of the present utility model are as follows: By covering the discharge cover onto the mixing cylinder, at this time, the first wedge ring and the second wedge ring are in contact and installed in cooperation. When the mixing cylinder rotates, with the assistance of the thrust bearing, the mixing cylinder rotates under the discharge cover, and the first wedge ring and the second wedge ring maintain sealed contact. Then, by injecting high-pressure air into the annular groove, the high-pressure air enters the ventilation holes through the annular groove and is blown out through the ventilation holes, so that the high-pressure air blows towards the inclined surface of the ring, achieving airtightness at the inclined surface and further strengthening the sealing function. Then, under the action of the air guide plate, the high-pressure air can be blown towards the bottom of the discharge cover to prevent material dust from accumulating at the bottom of the discharge cover.
