Description

Technical Field

[0001] The utility model relates to the technical field of pumping agent production, in particular to a reaction kettle for pumping agent production. Background Art

[0002] Pumping agent is made by mixing and stirring multiple admixtures (such as water reducer, retarder, quick setting agent, expansion agent, etc.). At present, multiple admixtures (referred to as mixed liquid) are often poured into a reactor, and then the mixed liquid is stirred by a stirring rod with stirring blades inserted into the reactor to obtain the required pumping agent.

[0003] However, the current reactor is an integrally formed hollow cylinder, and the size of the through hole at the upper end of the reactor for the stirring rod to extend into is fixed, which means that the sum of the lengths of the stirring blade and the stirring rod in the radial direction of the reactor must be less than or equal to the diameter of the through hole, while the diameter of the through hole is smaller than the diameter of the reactor, resulting in the lengths of the stirring blade and the stirring rod in the radial direction of the reactor being smaller than the diameter of the reactor, that is, the contact between the stirring blade and the mixed liquid in the reactor in the radial direction of the reactor is limited, resulting in the inability to quickly, fully and evenly stir the mixed liquid, thereby reducing production efficiency. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model aims to provide a reaction kettle for the production of pumping agents, which can improve the stirring efficiency, quickly and fully and evenly stir the mixed liquid, and improve the production efficiency.

[0006] Compared with the prior art, the beneficial effects of the present invention are:

[0007] The auxiliary stirring member of the utility model can shrink inwardly when the stirring shaft extends into the reactor body, and automatically expand when the stirring shaft is located in the reactor body, thereby increasing the length of the first stirring blade in the radial direction of the reactor body, and increasing the contact of the first stirring blade with the mixed liquid in the radial direction of the reactor body. Furthermore, the cooperation of the auxiliary stirring member, the first stirring blade and the stirring shaft can improve the stirring efficiency, quickly, fully and evenly stir the mixed liquid, and improve production efficiency.

[0008] As a preferred embodiment of the utility model, the auxiliary stirring member includes a second stirring blade, a connecting rod and a spring. One end of the second stirring blade is rotatably connected to one end of the first stirring blade. Both ends of the connecting rod are respectively connected to two adjacent first stirring blades. One end of the spring is connected to the second stirring blade, and the other end is connected to the connecting rod. When the spring is compressed, the lower end of the second stirring blade is close to the stirring shaft, and the distance between the two second stirring blades radially arranged along the reactor body is less than or equal to the diameter of the first through hole.

[0009] Beneficial effect: The second stirring blade can increase the radial length of the first stirring blade in the reactor body, as well as the contact surface of the reactor body with the mixed liquid in the axial direction. The connecting rod can connect the spring to ensure the connection between the spring and the second stirring blade, thereby limiting the second stirring blade, and can also serve as an auxiliary stirring shaft to drive the mixed liquid to be stirred in the axial direction of the reactor body.

Figure 2 As shown, the upper end surface of the reactor body 1 is provided with a first motor 3. Figure 3As shown, the first motor 3 is provided with a stirring assembly 4 which can extend into the reactor body 1 through the first through hole 101. Figure 4 As shown, the stirring assembly 4 includes a stirring shaft 401 connected to the first motor 3, and a plurality of first stirring blades 402 arranged along the height direction of the stirring shaft 401 and connected to the stirring shaft 401. In this embodiment, the stirring shaft 401 passes through the center of the first stirring blade 402, and the stirring shaft 401 may be provided with a plurality of first stirring blades 402 at intervals along the circumference of the stirring shaft 401. Auxiliary stirring members 403 that can expand automatically are symmetrically provided at both ends of the first stirring blade 402. When the stirring shaft 401 is extended into the reactor body 1, the auxiliary stirring member 403 is retracted inwardly. When the stirring shaft 401 is located in the reactor body 1, the auxiliary stirring member 403 automatically expands.

[0027] like Figure 4-5 As shown, in this embodiment, the auxiliary stirring member 403 includes a second stirring blade 4031, a connecting rod 4032 and a spring 4033. One end of the second stirring blade 4031 is rotatably connected to one end of the first stirring blade 402, and both ends of the connecting rod 4032 are respectively connected to two adjacent first stirring blades 402. One end of the spring 4033 is connected to the second stirring blade 4031, and the other end is connected to the connecting rod.
