Vibration stirring device capable of improving distribution uniformity of cement particles

Abstract

The invention discloses a vibration stirring device capable of improving the distribution uniformity of cement particles. The vibration stirring device capable of improving the distribution uniformityof the cement particles comprises a stock bin, a first vibration platform, a second vibration platform and a stirring mechanism, wherein a charge port is formed in the upper part of the stock bin, adischarge port with a valve is formed in the lower part of the stock bin, and shaft holes are formed in the two ends of the stock bin; the stirring mechanism comprises a stirring shaft, a stirring motor, a speed reducer, a first bearing seat and a second bearing seat; the two ends of the stirring shaft penetrate out of the corresponding shaft holes in a matching manner through elastic shaft seal,and are connected with one end of the first rotary shaft and one end of the second rotary shaft through a shaft coupling separately; the stirring motor, the speed reducer and the first bearing seat are arranged on a vibration surface of the first vibration platform; the stirring motor, the speed reducer and the other end of the first rotary shaft are sequentially connected; the first rotary shaftis supported on the first bearing seat in a matching manner; the second bearing seat is arranged on a vibration surface of the second vibration platform; and the other end of the second rotary shaft is supported on the second bearing seat in a matching manner. The device is capable of crushing cement balls and ash balls in a mixture through vibration, and uniformly distributing the cement balls and the ash balls into the mixture, and simple in structure.

Description

Technical field [0001] The invention belongs to the field of cement processing equipment, and specifically relates to a vibration stirring device capable of improving the uniformity of cement particle distribution. Background technique [0002] In all levels of highway pavement engineering, cement stabilized crushed stone base is the most used. At present, cement stabilized crushed stone base materials at home and abroad generally adopt self-falling or forced mixing technology. The above two methods are actually static mixing. The static mixing method can easily lead to uneven distribution of cement clusters and ash aggregates in the mixture, resulting in mixture segregation. The above-mentioned defects cause early cracks in the cement stabilized crushed stone base and induce cracks in the asphalt pavement. Therefore, improving the uniformity of cement particle distribution and thereby improving the durability of the road surface has become an urgent problem to be solved. Summar...

Problems solved by technology

[0002] In all grades of highway pavement projects, the cement-stabilized macadam base is the most widely used. At present, the cement-stabilized macadam base materials at home and abroad generally adopt self-falling or forced mixing technology. The above two methods are actually static mixing. The way of static mixing can easily lead to the uneven distribution of cement lumps and ash lumps in the mixture, resulting in segregation of the mixture. The above defects are caused by early cracks in the cement-stabilized macadam base, and thus induce cracks in the asphalt pavement Therefore, improving the uniformity of cement particle distribution and thus improving the durability of the pavement has become an urgent problem to be solved
