Abstract

The utility model belongs to the technical field of material stirring, and discloses a stirring tank for inorganic hydraulic cementing materials, which is mainly used for solving the problems of non-uniform stirring and low stirring efficiency of the existing stirring device. When the stirring mechanism works, the motor drives the rotating shaft to rotate so as to drive the water storage sleeve to rotate, and water flowing out of the water outlet holes in the water storage sleeve can be sprinkled into the tank body under the action of rotating centrifugal force, so that the contact area between solid raw materials in the tank body and the water in the mixing and stirring process is increased, and the stirring efficiency is improved. Furthermore, all the raw materials in the tank body are uniformly mixed and fully reacted; meanwhile, a mode of adding the raw materials layer by layer can be adopted, so that water can uniformly cover the surface of each layer of newly added raw materials in the tank body, and the raw materials in the tank body and the water are uniformly mixed under the rotary stirring action of the spiral stirring blades, thereby really achieving the effects of reaching the standard at one time without reworking, improving the stirring efficiency and saving the working time.

Description

Technical Field

[0001] The utility model belongs to the technical field of material stirring, and more specifically relates to a stirring tank used for inorganic hydraulic gelling materials. Background Art

[0002] Cementitious materials refer to materials that can bond granular materials (such as sand and gravel) or block materials (such as bricks and stones) into a whole in construction projects. Cementitious materials can be divided into organic cementitious materials and inorganic cementitious materials according to their chemical composition. Among them, inorganic cementitious materials can be divided into air-hardening cementitious materials and hydraulic cementitious materials according to the difference in hardening conditions. As the name suggests, air-hardening cementitious materials can only harden, maintain or develop strength in the air, and are suitable for dry environments, such as lime and water glass; hydraulic cementitious materials can not only harden in the air, but also better harden, maintain and continue to develop their strength in humid environments or water, such as cement.

[0003] The stirring device for inorganic hydraulic cementitious materials is generally a mixing tank or a mixing barrel, which is equipped with a stirrer. The raw materials enter the mixing tank or mixing barrel through a pipeline, and the motor drives the stirrer to start working to mix and stir the raw materials evenly. The stirrer can be a mechanical stirrer or a pneumatic stirrer, and different stirrers are selected according to different needs; the material of the mixing tank or mixing barrel also needs to be selected according to the properties of the raw materials to ensure that no chemical reaction or physical change occurs during the mixing and stirring process.

[0004] In actual applications, we found that when using existing stirring devices for stirring, all mixed raw materials are usually placed in a tank or barrel together with water, and then the motor is started to drive the stirrer for stirring. This method can easily lead to the final mixed material not meeting the standards when the stirring device is fully loaded, that is, the raw materials and water are not mixed evenly and there is agglomeration. To avoid this situation, the stirring time needs to be increased accordingly, which also reduces work efficiency. Utility Model Content

[0005] The utility model aims to provide a stirring tank for inorganic hydraulic gelling materials, aiming to solve the problems that the existing stirring devices for such materials are prone to uneven stirring and low stirring efficiency.

The raw materials can be directly poured into the feed channel manually or by a feeding device. The raw materials will slowly slide into the tank body under the action of their own gravity, which makes feeding convenient and saves manpower. BRIEF DESCRIPTION OF THE DRAWINGS

Transmission connection, more specifically, the upper end of the rotating shaft 6 is connected to the output shaft of the motor 1 through a coupling, and the rotating shaft 6 located inside the tank body 1 is connected with a spiral stirring blade 7; the rotating shaft 6 is also provided with a water storage sleeve 8, and the water storage sleeve 8 is located above the spiral stirring blade 7 and close to the top of the tank body 1; the upper end of the water storage sleeve 8 is open, and the lower end is closed and connected to the rotating shaft 6, and a plurality of water outlet holes 9 are provided on the water storage sleeve 8; the water inlet 3 is arranged on the upper end surface of the tank body 1, and the position of the water inlet 3 is within the coverage area of ​​the open upper end of the water storage sleeve 8.

[0028] The stirring tank in this embodiment is connected with a water storage sleeve 8 on its rotating shaft 6, so that the water storage sleeve 8 can rotate with the rotating shaft 6, and the position of the water inlet 3 is set within the covering area of ​​the upper end of the water storage sleeve 8, so that the water used for mixing the raw materials will first enter the space of the water storage sleeve 8 through the water inlet 3, and then flow into the tank body 1 through the water outlet 9 on the water storage sleeve 8 for mixing. When the stirring mechanism is working, the motor 2 drives the rotating shaft 6 to rotate, thereby driving the water storage sleeve 8 to rotate, and the water flows out from the water outlet 9 on the water storage sleeve 8. The water will be sprinkled into the tank body 1 under the action of the rotating centrifugal force, thereby increasing the contact area between the solid raw materials and the water inside the tank body 1 during the mixing and stirring process, thereby achieving uniform mixing and sufficient reaction of the raw materials in the tank body 1; at the same time, the utility model can adopt the method of adding raw materials layer by layer, so that water can evenly cover the surface of each layer of newly added raw materials in the tank body 1, and then under the rotating stirring action of the spiral stirring blade 7, the raw materials and water in the tank body 1 are evenly mixed, truly achieving the goal at one time without rework, improving the stirring efficiency, and saving working time.

More specifically, the water outlet holes 9 are evenly arranged on the lower surface of the sprinkler rods 10.

[0031] It should be noted that in order to avoid residual water in the water storage space in the water storage sleeve 8, the bottom surface of the space in the middle of the sprinkler rod 10 is set flush with the bottom surface of the space of the water storage sleeve 8, so that the water in the water storage sleeve 8 will always flow into the sprinkler rod 10 and flow into the tank body 1 through the water outlet 9.

[0032] The mixing tank in this embodiment increases the watering coverage area of ​​the water storage sleeve 8 by adding a watering rod 10, thereby further improving the mixing uniformity of the materials inside the tank body 1.

There are two feed ports 4 in total, and the two feed ports 4 are symmetrically arranged on both sides of the upper part of the tank body 1.

[0038] It should be noted that, in order to facilitate feeding, the feed channel 12 can be set to be conical, that is, the cross-section of the connecting end of the feed channel 12 and the feed port 4 on the tank body 1 is smaller than the cross-section of the other end of the feed channel 12.

[0039] The mixing tank in this embodiment can directly pour the raw materials into the feeding channel 12 manually or by a feeding device, and the raw materials will slowly slide into the tank body 1 under the action of their own gravity, which makes feeding convenient and saves manpower.
