They are now widely used in the construction of highways, railways, bridges, mines, tunnels, water conservancy, urban construction and other projects, as well as leak prevention and plugging, rapid bottom concrete construction, and concrete emergency rescue and reinforcement. Alkali-free accelerators refer to alkali-free concrete accelerators, which are characterized by their main components of aluminum sulfate and organic amines, a slightly yellow uniform liquid, completely environmentally friendly, alkali-free and chlorine-free, and the setting time can be adjusted arbitrarily by the amount of admixture, making it safe and convenient to use.

[0021] like Figure 1As shown, a lifting outer tube 8 is provided in the inner cavity of the storage tank structure, and a lifting outlet 9 communicating with the inner cavity is connected to the outer peripheral wall of the lifting outer tube 8. A spiral core shaft 6 is passed through the inner cavity of the lifting outer tube 8, and a lifting spiral blade 5 adapted to the lifting outer tube 8 is wound and fixed on the spiral core shaft 6. The rotation of the spiral core shaft 6 can guide the liquid, and the rotating spiral core shaft 6 and the lifting spiral blade 5 can guide the liquid, and introduce and export the liquid into the lifting outer tube 8. When the liquid is introduced into the lifting outer tube 8, the liquid is sprayed outward from each lifting outlet 9 provided on the lifting outer tube 8, and the liquid material in the storage tank 10 is lifted, sprayed and stirred. When the liquid is exported from the lifting outer tube 8, the liquid flows into the lifting outer tube 8 from each lifting outlet 9 provided on the lifting outer tube 8, so that the material in the storage tank 10 enters the lifting outer tube 8 and is discharged from the bottom, thereby achieving the effect of sufficient stirring and mixing.

[0022] like Figure 1 As shown, this embodiment also includes a stirring shaft 7 disposed in the inner cavity of the storage tank structure and disposed on both sides of the lifting outer tube 8, and a plurality of groups of stirring paddles 4 distributed along the axial direction thereof are mounted on the stirring shaft 7. By providing the stirring shaft 7 and the plurality of groups of stirring paddles 4, the stirring effect of the utility model can be improved.

[0023] like Figure 1 As shown, this embodiment further includes a drive mounting frame 12 fixedly connected to the tank cover 11, and a drive device 13 installed on the drive mounting frame 12. The drive device 13 can drive the spiral core shaft 6 and the stirring shaft 7 to rotate synchronously and move up and down synchronously.

[0024] like Figure 2 As shown, in this embodiment, the driving device 13 includes a second mounting sleeve 13-5 fixed on the driving mounting frame 12 and coaxially fixed with the lifting outer tube 8, and the second mounting sleeve 13-5 is fixed to the lifting outer tube 8. In addition, a sealing ring is arranged on the upper part of the spiral core shaft 6, and the sealing ring is in friction contact with the inner wall of the second mounting sleeve 13-5, thereby preventing the liquid in the storage tank 10 from flowing into the rotating drive component 13-3 and affecting the operation.

[0025] On both sides of the second mounting sleeve 13-5, there are respectively provided first mounting sleeves 13-2 which are arranged coaxially with the two groups of stirring shafts 7, and each first mounting sleeve 13-2 is fixedly connected to the driving mounting frame 12. A spline shaft 13-4 is penetrated in the second mounting sleeve 13-5 and each first mounting sleeve 13-2, and the spline shaft 13-4 and the corresponding mounting sleeve can rotate relative to each other in the circumferential direction and move relative to each other in the axial direction. Each spline shaft 13-4 is respectively connected to the spiral core shaft 6 and the two stirring shafts 7. The driving device 13 also includes a lifting drive assembly 13-1 for driving each spline shaft 13-4 to move relative to the mounting sleeve in the axial direction, and also includes a rotating drive assembly 13-3 for driving the spline shaft 13-4 to rotate relative to the mounting sleeve in the circumferential direction.

[0026] like Figure 2 and Figure 3 As shown, the rotary drive assembly 13-3 includes a bearing mounting sleeve 13-3-5 fixedly connected to the upper part of each mounting sleeve, and also includes a plurality of spur gear sleeves 13-3-3 rotatably connected to each bearing mounting sleeve 13-3-5 through a rolling bearing. A spline groove matching the spline of the corresponding spline shaft 13-4 is provided at the center of each spur gear sleeve 13-3-3. Through the above-mentioned spline setting, each spline shaft 13-4 can move longitudinally in the axial direction relative to the first and second mounting sleeves, and at the same time It can also ensure that the spur gear sleeve 13-3-3 and the corresponding spline shaft 13-4 can rotate synchronously. Since the spur gear sleeve 13-3-3 is rotatably connected with the bearing mounting sleeve 13-3-5, and the bearing mounting sleeve 13-3-5 is fixedly connected with the corresponding first mounting sleeve / second mounting sleeve, the spur gear sleeve 13-3-3 can rotate relative to the first mounting sleeve / second mounting sleeve, thereby achieving the purpose of relative rotation of the corresponding spline shaft 13-4 and the corresponding mounting sleeve in the circumferential direction and relative movement in the axial direction.

[0027] like Figure 2 As shown, the rotary drive assembly 13-3 also includes a driven gear 13-3-4 meshingly connected between two adjacent groups of spur gear sleeves 13-3-3, and the driven gear 13-3-4 is keyed to a driven shaft rotatably connected to the drive mounting frame 12, and the above-mentioned driven shaft is rotatably connected through a sleeve fixed to the drive mounting frame 12 and a rolling bearing installed in the sleeve.

The lifting drive member 13-1-1 is a linear driving member, which can be a hydraulic cylinder, a cylinder or an electric push rod. In this embodiment, the lifting drive member 13-1-1 is a cylinder.

[0029] By setting up the lifting drive component 13-1, the spiral core shaft 6 and the stirring shaft 7 can be driven to rotate and move up and down at the same time, so that the spiral core shaft 6 and the stirring shaft 7 can perform lifting stirring work, so that the liquid accelerator in the tank body can be stirred in all directions to solve the problem of condensation and crystallization inside the accelerator itself, avoid the problem of affecting the use of the liquid accelerator when mixing the liquid accelerator with concrete, and ensure the practicality of the liquid accelerator.

[0030] like Figure 1 As shown, the present embodiment also includes a stirring paddle 4 fixedly connected to the lower end of the spiral core shaft 6, and also includes a discharge spiral blade 3 wound and fixedly connected to the lower part of the spiral core shaft 6. The discharge spiral blade 3 can be extended into the discharge port 2. When the discharge spiral blade 3 rotates, the discharge port 2 can be cleaned to avoid blockage of the discharge port 2 due to crystallization of the quick-setting agent, thereby affecting the discharge operation.

[0031] Working process:

[0032] After the liquid quick-setting agent is placed in the storage tank 10, the rotary drive motor 13-3-1 in the drive device 13 can be started at a fixed time to drive the spiral mandrel 6 and the stirring shaft 7 to rotate, thereby driving the stirring paddle 4 and the lifting spiral blade 5 to rotate, and stirring the liquid in the storage tank 10; at the same time, the rotation of the spiral mandrel 6 can guide the liquid, and the rotating spiral mandrel 6 and the lifting spiral blade 5 can guide the liquid to introduce and export the liquid into the lifting outer tube 8, thereby lifting, spraying and stirring the liquid material in the storage tank 10, cooperating with the stirring shaft 7 and the multiple groups of stirring paddles 4 installed thereon, so that the liquid in the storage tank 10 can achieve the effect of sufficient stirring and mixing;

[0033] When it is necessary to adjust the stirring height of the spiral core shaft 6 and the stirring shaft 7, start the lifting drive 13-1-1 to make the spiral core shaft 6 and the stirring shaft 7 move longitudinally, and then adjust the height of the spiral core shaft 6 and the stirring shaft 7 in the storage tank 10, so that the stirring position of the spiral core shaft 6 and the stirring shaft 7 is changed.
