Problems solved by technology

Though this device has solved, and the cement slurry is easy to drip onto the process production line and the curing barrel and cause the problem of contamination, but there are still the following shortcomings: 1, the stirring paddle of this device is fixed in the curing barrel, after causing the cement to solidify, stirring The oars are processed together with the curing barrel, resulting in unnecessary waste; 2. The above-mentioned first deficiency is not solved

Embodiment 1

[0040] Such as Figure 1-7 As shown, a cement solidification device for radioactive waste liquid treatment includes a moving mechanism 1. The moving mechanism 1 is mainly composed of a moving trolley 101, a relief groove 102, and a fixing frame 103. The fixing frame 103 is provided with a groove 1031, and also includes The stirring mechanism 2 arranged on one side of the fixed frame 103 and the feeding mechanism 3 arranged on the other side of the fixed frame 103, the stirring mechanism 2 includes a mounting frame 201, a stirring and curing bucket 202, a sealing upper cover 203, a feeding head 204, and a stirring assembly 205 , the lower sealing plate 206, the installation frame 201 is connected to the top of the mobile trolley 101 by bolts, the inside of the installation frame 201 is fixedly equipped with a stirring and curing bucket 202, and the top of the stirring and curing bucket 202 is connected with a sealing upper cover 203 by screws, and the top of the sealing upper co...

Embodiment 2

[0042] Such as Figure 8 As shown, the difference between Embodiment 2 and Embodiment 1 is that several additional rods 20545 are welded on the stirring rod 20542, and the additional rods 20545 vertically penetrate through the stirring rod 20542, which improves the stirring efficiency.

[0043] A method for using a cement solidification device for radioactive waste treatment, comprising the following steps:

[0044] Step 1: First move the whole device to a suitable position, and then power on;

[0045] Step 2: Pour the curing agent from the feeding head 204 into the stirring and curing barrel 202, then connect the air pipe to the feeding head 204, and then place the material barrel 307 on the lifting frame 301, and make the material barrel 307 close to the arc stop Plate 306, then turn the lead screw 3022, the lead screw 3022 drives the pressing plate 3023 to descend, and the pressing plate 3023 drives the fastening cover 3024 to descend, so that the fastening cover 3024 is t...

Abstract

The invention discloses a cement solidification device for radioactive waste liquid treatment and a using method thereof. The cement solidification device comprises a moving mechanism; the moving mechanism is mainly composed of a moving trolley, a receding groove and a fixed frame, wherein a groove is formed in the fixed frame; the device also comprises a stirring mechanism which is arranged on one side of the fixed frame, and a feeding mechanism which is arranged on the other side of the fixed frame; the stirring mechanism comprises a mounting frame, a stirring curing barrel, a sealing uppercover, a feeding head, a stirring assembly and a lower sealing plate; the mounting frame is connected to the top of the moving trolley through bolts. Due to the arrangement of the stirring rod in thestirring assembly, the problem of contamination caused by dripping of materials on a process production line and a curing barrel is solved, and the problem of unnecessary waste of the stirring frame is also solved; due to the arrangement of the feeding mechanism, the function of safely adding materials is achieved, and the labor intensity is further reduced.

Description

technical field [0001] The invention relates to the technical field of radioactive waste liquid treatment, in particular to a cement solidification device for radioactive waste liquid treatment and an application method thereof. Background technique [0002] Cement solidification is the main method for dealing with radioactive wet waste at present. Among them, the loading and stirring of materials (including waste and solidified substrate) are two key steps in cement solidification. According to the difference between these two steps, the existing cement solidification The process mainly consists of two methods of stirring inside the barrel and stirring outside the barrel. The current cement curing process of stirring in the barrel is mature and widely used, but it also has obvious disadvantages and shortcomings. 1. When adding materials into the barrel, it is necessary to lift the materials to the top of the curing barrel for work, so that the materials are easily spilled a...
