Description

Technical Field

[0001] The utility model relates to the field of mixers, in particular to a dust suppression mixer. Background Art

[0002] Current mixers often have serious dust problems during material conveying and mixing, which not only affects the air quality of the working environment and increases the health risks of workers, but also causes environmental pollution. The material conveying system of the mixer usually adopts direct dumping or simple conveying methods. This method is prone to generate a lot of dust when the material enters the mixing barrel, and the material is unevenly distributed, affecting the mixing effect. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides a dust suppression mixer.

[0004] The technical solution adopted by this utility model:

[0005] The top and the bottom of the inner wall of the mixing barrel are fixedly connected with fixed frames, and the two fixed frames are rotatably connected with the rotating shaft, and the bottom end of the rotating shaft is rotatably connected with the base, and the bottom end of the rotating shaft is rotatably connected with the base, and the outer wall of the mixing barrel is fixedly connected with a spiral feeding reamer, and the feeding reamer is located between the two fixed frames, and the feeding reamer is loosely matched with the inner wall of the feeding pipe. The top of the feeding pipe is fixedly connected with a motor, and the output shaft of the motor passes through the top of the feeding pipe and is fixedly connected to the top of the rotating shaft. The outlet shaft is rotatably connected to the feeding pipe, and the outer wall of the feeding pipe is rotatably sleeved at the upper position, and the sleeve is located in the mixing barrel. The mixing frame is rectangular, and the outer wall of the sleeve is fixedly connected to the upper part of the mixing frame. There are two mixing frames, and the two mixing frames are vertically distributed on the outer wall of the sleeve. The side wall of the mixing frame is gap-matched with the inner wall of the mixing barrel. The bottom centers of the two mixing frames are cross-fixed to each other, and the bottom of the rotating shaft passes through the bottom centers of the two mixing frames. The bottom center of the mixing frame is fixedly connected to the rotating shaft, and a mixing blade is fixedly connected between the upper and bottom parts of the outer wall of each mixing frame. The mixing blade is spiral, and the two ends of the mixing blade are respectively fixedly connected to the right side of the upper part and the left side of the bottom part of the outer wall of the mixing frame. The bottom of the mixing barrel is fixedly connected with a discharge pipe, and a valve is set on the discharge pipe. The top of the mixing barrel is fixedly connected with a feed hopper 2 and a water inlet pipe, and the top of the outer wall of the feeding pipe is fixedly connected with a feed hopper 1, and the feed hopper 1 is located above the mixing barrel.

[0006] Beneficial effects of the utility model:

[0007] The utility model uses a spiral feeding reamer and a feeding port between a feeding pipe and a base, so that materials (such as cement ash) can be smoothly conveyed from the feeding pipe to the mixing barrel, thereby avoiding the flying of dust generated during the feeding process. The motor drives the rotating shaft to rotate, which not only drives the feeding reamer to rotate and convey materials, but also drives the mixing frame and the mixing blades to rotate, thereby achieving uniform mixing of materials. The mixing frame scrapes off the materials adhered to the inner wall of the mixing barrel during the rotation process, effectively preventing the accumulation and agglomeration of the materials on the inner wall of the mixing barrel, ensuring the cleanliness of the mixing barrel, and improving the mixing effect.
