Two-stage pulping machine

Abstract

The invention belongs to the technical field of pulping engineering machinery, and particularly relates to a two-stage pulping machine which comprises a base, a first material box, a second material box, a motor and a controller. The upper end of the base is fixedly connected with the first material box and the second material box. The distance between the first material box and the base is largerthan that between the second material box and the base. The section of the first material box is in a U shape, the first material box is obliquely arranged relative to the base, and a feeding hole isformed in the upper end of the first material box. The feeding hole accounts for a half of the upper end of the first material box. A first rotating rod is rotationally connected between the two inner walls of the first material box. Blades on the first rotating rod are driven by the motor to rotate, and scraping blocks scrape first meshes after being impacted by the blades, so that the effect ofdredging the first meshes in the material pulping process is achieved, then the efficiency of slurry in the first material box entering the second material box is guaranteed, and therefore, the slurry outlet efficiency of the two-stage pulping machine is improved, and meanwhile, the quality of slurry is also improved.

Description

technical field [0001] The invention belongs to the technical field of pulping engineering machinery, and in particular relates to a two-stage pulping machine. Background technique [0002] Material slurrying is mainly used in coal mine water prevention and fire prevention grouting projects and dam reinforcement projects. In dam reinforcement projects, loess, clay, sand, fly ash and other materials are mixed with water to make uniform slurry or colloid , and then fill the grout in the leaks and gaps of the dam body and dam foundation, so as to prevent the leakage of the embankment, and strengthen it through grouting to form an anti-seepage body; currently there are many kinds of material slurrying equipment on the market, and the most widely used is double However, during the preparation process of the two-stage pulping machine, due to the uneven pulping of the material in the primary pulping tank, the material particles will be separated between the primary pulping tank and...

[0002] Material slurrying is mainly used in coal mine water prevention and fire prevention grouting projects and dam reinforcement projects. In dam reinforcement projects, loess, clay, sand, fly ash and other materials are mixed with water to make uniform slurry or colloid , and then fill the grout in the leaks and gaps of the dam body and dam foundation, so as to prevent the leakage of the embankment, and strengthen it through grouting to form an anti-seepage body; currently there are many kinds of material slurrying equipment on the market, and the most widely used is double However, during the preparation process of the two-stage pulping machine, due to the uneven pulping of the material in the primary pulping tank, the material particles will be separated between the primary pulping tank and the secondary pulping tank. The screen is clogged, which affects the efficiency of the materials in the primary pulping tank entering the secondary pulping tank, thereby affecting the pulping efficiency of the two-stage pulping machine

[0003] There have also been some technical solutions about two-stage pulping machines in the prior art. For example, a Chinese patent with application number CN201210149375.5 discloses a two-stage pulping machine, which consists of two-stage pulping mechanisms, including one-stage Slurry tank, primary runner, secondary pulping tank, secondary runner, power mechanism and transmission mechanism; primary runner and secondary runner are respectively installed in the primary pulping tank and the secondary pulping tank and It can be rotated; the center of rotation of the primary runner is higher than that of the secondary runner. Above the wheel, the outlet of the first-stage splitter box is connected to the lower part of the second-stage pulping tank through the connecting pipe, and the power is transmitted to the first-stage runner through the transmission mechanism, and then to the second-stage runner through the transmission mechanism; the second-stage runner Continuous rotary agitation can adapt to various materials, and can also eliminate the phenomenon of ash in water; at the same time, the two-stage rotary agitation also plays the role of flow adjustment, which can realize continuous pulping; The pulping is uneven, so that the material will block the screen between the primary pulping tank and the secondary pulping tank, thereby affecting the efficiency of the materials in the primary pulping tank entering the secondary pulping tank, and thus affecting the double pulping tank. The pulping efficiency of the first-stage pulper, which in turn causes the limitation of this technical solution
