Description

Technical Field

[0001] The utility model belongs to the technical field of quick-setting agent production equipment, and in particular relates to an alkali-free quick-setting agent storage device which is convenient for discharging. Background Art

[0002] Accelerators are admixtures that can make concrete set and harden quickly, and can form sufficient strength in a very short time. 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.

[0003] In the prior art, liquid accelerators are mostly packaged in plastic barrels, with a sealed barrel cover simply added to the barrel, which is connected to the barrel body by pressure. The alkali-free liquid accelerator is stored static for a long time, resulting in stratification and crystallization. The aluminum sulfate particles are located in the lower layer of the barrel body, and other liquids are located in the upper layer of the barrel body. The content of aluminum sulfate particles in each part is different. When the stratified alkali-free liquid accelerator is used in concrete, it is easy to cause uneven alkali-free accelerators in different batches of concrete, and uneven alkali-free liquid accelerators in various locations of the same batch of concrete, thereby affecting the performance of the concrete. If the alkali-free liquid accelerator is stored in a barrel body with a discharge pipe, the aluminum sulfate particles precipitated in the lower layer will easily block the discharge pipe due to its thick consistency and poor fluidity when flowing through the discharge pipe.

[0004] In the prior art, a stirring structure is usually provided at the discharge port to solve the problems of slow discharge and blockage. However, the position of the stirring structure in the storage device is fixed, and the blockage problem can only be solved at the fixed position of the discharge port. In actual production, it is found that when the discharge efficiency is low, the material in the storage device not only accumulates in the discharge port area, but also accumulates in the area above the discharge port. At this time, the stirring structure fixedly provided in the storage device cannot meet the actual production needs. Therefore, it is urgent to design an alkali-free quick-setting agent storage device to solve the above problems. Utility Model Content

[0005] The utility model provides a non-alkali quick-setting agent storage device with reasonable structural design and convenient material discharge in order to solve the technical problems existing in the known technology. The utility model can prevent blockage from affecting the normal operation of the device, thereby improving the working efficiency and practicality.

[0006] The utility model adopts the following technical scheme to solve the technical problems existing in the known technology: an alkali-free quick-setting agent storage device convenient for discharging comprises a storage tank structure with a discharge pipe arranged at the bottom, a stirring shaft arranged coaxially with the discharge pipe is arranged in the inner cavity of the storage tank structure, stirring spiral blades are coiled on the upper part of the outer peripheral wall of the stirring shaft, and material inlet spiral blades are coiled on the lower part of the outer peripheral wall; it also comprises an upper stirring rod and a lower stirring rod installed on the stirring shaft, and a plurality of stirring spiral ribbons are installed between the upper stirring rod and the stirring shaft and between the lower stirring rod and the stirring shaft; a spline shaft extending to the outside of the storage tank structure is connected to the upper end of the stirring shaft, and it also comprises a driving assembly installed on the storage tank structure for driving the spline shaft to rotate and move longitudinally.

[0007] The advantages and positive effects of the utility model are as follows: the utility model provides an alkali-free quick-setting agent storage device that is convenient for discharging. By setting a storage tank structure, it can be used to store liquid quick-setting agent. By setting a rotatable stirring shaft, and stirring spiral blades and stirring ribbons installed on the stirring shaft, the material in the storage tank structure can be stirred, so that the liquid quick-setting agent is fully mixed; by setting a spline shaft connected to the stirring shaft and a driving assembly, the stirring shaft can be driven to perform lifting rotation, so that the liquid quick-setting agent in the storage tank body can be stirred in all directions. At the same time, in conjunction with the material inlet spiral blade installed at the lower part of the stirring shaft, the material in the discharge pipe, above the discharge pipe and around the discharge pipe can be stirred, so as to avoid the blockage of the discharge pipe affecting the discharge operation of the storage device, and also avoid the deposition of materials above and around the discharge pipe affecting the discharge operation. The utility model can prevent blockage from affecting the normal operation of the device, thereby improving work efficiency and practicality.

[0022] like Figure 1 As shown, a spline shaft 15 extending to the outside of the storage tank structure is connected to the upper end of the stirring shaft 9, and also includes a drive assembly installed on the storage tank structure for driving the spline shaft 15 to rotate and move longitudinally.

[0023] In this embodiment, the drive assembly includes a drive mounting frame 13 mounted on the storage tank structure, and a mounting sleeve assembly 16 movably connected to the spline shaft 15 is mounted on the drive mounting frame 13. Figure 2 In this embodiment, the mounting sleeve assembly 16 includes an outer mounting sleeve 16-3 mounted on the driving mounting frame 13, an inner rotating sleeve 16-2 is rotatably connected to the outer mounting sleeve 16-3 through a rolling bearing, and a spline sleeve 16-1 is coaxially mounted on the inner rotating sleeve 16-2, wherein the spline sleeve 16-1 is spline-matched with the spline shaft 15. Through the above arrangement, it can be ensured that the spline shaft 15 can rotate relative to the outer mounting sleeve 16-3 in the circumferential direction, and the spline shaft 15 can move relative to the outer mounting sleeve 16-3 in the axial direction.

[0024] In order to drive the spline shaft 15 to rotate relative to the outer mounting sleeve 16-3, the drive assembly further includes a rotation drive component 14 mounted on the drive mounting frame 13, which is used to drive the spline shaft 15 to rotate. Figure 2As shown, in this embodiment, the rotary drive assembly 14 includes a rotary drive member 14-1 connected to the drive mounting frame 13. In this embodiment, the rotary drive member 14-1 is a motor. A rotary transmission pair 14-2 is installed between the output shaft of the rotary drive member 14-1 and the inner rotary sleeve 16-2, wherein the rotary transmission pair 14-2 is a pulley transmission pair, mainly including a driving pulley keyed on the output shaft of the rotary drive member 14-1, and also including a driven pulley keyed on the inner rotary sleeve 16-2, and a belt in a closed state is connected between the driving pulley and the driven pulley.

[0025] In order to drive the spline shaft 15 to move longitudinally relative to the outer mounting sleeve 16-3, the drive assembly further includes a longitudinal drive structure mounted on the drive mounting frame 13, which is used to drive the spline shaft 15 to move longitudinally.

The scraper plate 8 is installed at the outer ends of the upper stirring rod 10 and the lower stirring rod 7.

[0027] Working principle:

[0028] After the alkali-free quick-setting agent is injected into the storage tank body 4, the rotary drive member 14-1 in the rotary drive assembly 14 can be started at a fixed time to drive the inner rotary sleeve 16-2 and the spline sleeve 16-1 to rotate. Since the spline shaft 15 and the spline sleeve 16-1 are spline-matched, the rotation of the spline sleeve 16-1 can drive the spline shaft 15 to rotate, and then drive the stirring shaft 9, the stirring spiral blade 5, the material inlet spiral blade 3, and the upper and lower stirring rods to rotate, so as to stir the liquid in the storage tank body 4, so that the material in the storage tank body 4 is fully stirred; in addition, when the stirring shaft 9 rotates, it can drive the scraper plates 8 installed on the upper and lower stirring rods to rotate around the neutral line of the stirring shaft 9, so as to scrape the inner wall of the storage tank body 4;

[0029] When it is necessary to adjust the stirring height of the stirring shaft 9 and the material port spiral blades 3, start the lifting drive 19 to make the stirring shaft 9 and the material port spiral blades 3 move longitudinally, and then adjust the height of the stirring shaft 9 and the material port spiral blades 3 in the storage tank body 4, so that the material port spiral blades 3 can move longitudinally in the discharge pipe 2. By driving the stirring shaft 9 to move longitudinally, the discharge pipe 2 can be prevented from being blocked by sediment. At the same time, the deposited materials above and around the discharge pipe 2 can also be stirred, thereby facilitating the discharge of the storage device.
