The invention discloses a sand mixing machine for improving the uniformity of the material, including a grinding wheel and a roller in the sand mixing tube, and a feeding hopper on the top of the sand mixing barrel, and a plurality of feeding holes in the bottom of the feed hopper are evenly arranged in the bottom of the feed hopper, and the feeding pipe is connected in the sand mixing cylinder below the feeding hole, and the air blowhole is evenly distributed on the side wall of the feeding pipe and the sand is mixed. There is a hot air pipe on the side wall of the barrel, and an inverted conical rotating plate is provided under the feeding tube, and a plurality of dump holes are evenly arranged on the rotating plate. The bottom of the mixer barrel is provided with a vertical mixing shaft, and the two sides of the mixing shaft are connected vertically with a branch, and the end part of the support rod is connected with a circular arc scraper. The mixing machine of the invention can not only achieve uniform feeding, but also can heat and dry the material surface to remove the moisture, improve the uniformity of the mixing between the materials, and can continuously scrape the material on the inner wall, avoid the material sticking to the inner wall, and make the crushing and mixing of the sand more thorough. Improve the quality and production efficiency.
【技术实现步骤摘要】
提高出料均匀性的混砂机
本专利技术涉及一种混砂机,具体涉及提高出料均匀性的混砂机。
技术介绍
混砂机是使型砂中各组分均匀混合,并使黏结剂有效地包覆在砂粒表面的设备。混砂机(sandmixer)利用碾轮与碾盘的相对运动,将置于两者间的物料受到碾压兼磨削的作用而粉碎物料,混砂机在粉碎物料的同时还将物料混合。是生产免烧砖、灰砂砖、水泥砖、耐火砖、粉碎和混合粉煤灰、锅炉炉渣、尾矿渣及工业废渣作制砖原料的理想设备。现有的混砂机很多物料在进料时都带有一定的湿气与潮气,因此物料在粉碎混合过程中很容易结块,若是加入粘结剂也不利于物料之间的均匀的混合,而且砂石中存在很大尺寸的物块,很容易对碾轮与碾盘造成损坏;同时破碎后的某些砂石还会粘在机器的内壁上,不仅使得破碎不彻底而且造成物料的损失,难以清洗内壁。
