Description

Technical Field

[0001] The invention relates to the technical field of dry-mix mortar equipment, and in particular to a dry-mix mortar anti-segregation packaging device. Background Art

[0002] Dry mortar is also called mortar dry powder or dry mixed mortar. It is a granular or powdered mixture made by mixing fine aggregates dried, screened and processed by professional manufacturers with inorganic adhesives, mineral admixtures and additives in a certain proportion. It can be produced into a series of products with multiple specifications according to the requirements of construction units, and then sold to construction units for use, so it is also known as "commercial mortar". Due to the different requirements of dry mortar for the material's anti-shrinkage, anti-cracking, thermal insulation, waterproof and moisture-proof properties, the different workability, water retention and setting time required for construction can be strictly controlled and accurately measured through scientific formulas. Therefore, its quality is guaranteed, which solves the problem that the traditional process ratio is difficult to grasp, and ensures that the construction users can meet the quality requirements of the construction technical standards. At the same time, the use of dry mortar also improves the dirty, messy and poor environment of traditional construction sites, which is conducive to changing the environment; in addition, dry mortar can also be mixed with fly ash, construction waste and other admixtures to turn waste into treasure, recycle and save resources.

[0003] After the various components of dry-mix mortar are batched and mixed, it is impossible to transport all of them directly to the construction site. They need to be temporarily stored in storage tanks and taken out at any time according to the needs of the construction site. At present, when storing dry-mix mortar, the finished dry-mix mortar after being mixed by the mixer is directly placed in the storage tank through an elevator. Since dry-mix mortar is a mixture of materials with different particle sizes and densities, the air resistance during the free fall process is also different, so the falling speed is also different. The material with high density reaches the bottom first, and the material with low density floats on the upper surface, which greatly reduces the uniformity of the dry-mix mortar, that is, segregation occurs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a dry mortar anti-segregation packaging device, in which a baffle is arranged in the packaging barrel to prevent the dry mortar that falls after stirring from segregating.

DETAILED DESCRIPTION

[0024] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figure 1 and Figure 2 As shown, a dry mortar anti-segregation packaging device comprises:

[0026] A mixing drum 1, the mixing drum 1 comprises a drum body 11, a first feed port (not shown), a hatch 12 and a mixing shaft 13, the mixing drum 1 is arranged horizontally, the feed port is arranged on one side of the drum body 11, the hatch 12 is located on the lower surface of the drum body 11, a horizontal mixing shaft 13 is arranged in the mixing drum 1, a mixing blade 14 is arranged on the mixing shaft 13, and the mixing shaft 13 is connected to a motor;

[0027] A packaging barrel 2, the packaging barrel 2 is located below the mixing drum 1, and the axis of the packaging barrel 2 is perpendicular to the axis of the mixing drum 1; the packaging barrel 2 comprises a feed inlet 21, a barrel body 22 and a discharge port 24, the feed inlet of the packaging barrel 2 is connected to the hatch 12 of the mixing drum 1, the discharge port 24 is located at the lower end of the barrel body, and a baffle is provided in the packaging barrel 2, the baffle is radially arranged on the barrel body and extends obliquely downward;

[0028] The cross-section of the packaging barrel 2 is funnel-shaped, and the barrel body includes a first barrel body 221, a second barrel body 222, a third barrel body 223 and a discharge pipe 23 from top to bottom. The first barrel body 221 is a truncated cone column with a small top and a large bottom, the second barrel body 222 is a cylinder, and the third barrel body 223 is a truncated cone with a large top and a small bottom. The discharge pipe 23 is a cylinder, and the feed port is arranged at the upper end of the first body, and the discharge port 24 is located at the bottom end of the discharge pipe 23. A flow valve is provided on the discharge pipe 23.

[0029] The anti-segregation packaging device for dry-mixed mortar of the present invention has a horizontally arranged mixing drum 1 that can fully mix the raw materials to form dry-mixed mortar, a packaging barrel 2 connected below the mixing drum 1, a material outlet below the packaging barrel 2, and a baffle 26 inside the packaging barrel 2. The baffle 26 reduces the flow rate of the dry-mixed mortar, effectively preventing the dry-mixed mortar from segregating during the vertical fall process, thereby improving the mixing uniformity of the dry-mixed mortar, ensuring production quality, reducing the labor of workers, and improving production efficiency.

[0030] There are two discharge pipes 23, and the discharge pipes 23 are located below the two sides of the third barrel body 223. A recessed portion 25 is provided at the lower end of the third barrel body 223, and the recessed portion 25 is located between the two discharge pipes 23. The recessed portion 25 is in the shape of a cone. Two discharge ports 24 can pack faster than one discharge port 24, which can increase the capacity of the packaging barrel 2 and reduce segregation. When the height of the recessed portion 25 is too large, the volume of the packaging barrel 2 is reduced; when the height of the recessed portion 25 is too small, the slope is small, and material is easily accumulated. The bottom-to-height ratio of the recessed portion 25 is 1.5-3. In this embodiment, the bottom-to-height ratio of the recessed portion 25 is 2, and the setting of the recessed portion 25 facilitates the discharge of the discharge port 24 and avoids material accumulation.

[0031] At least one set of baffles is disposed in the packaging barrel 2, and the baffles are symmetrically arranged at the upper ends of the discharge pipes 23, respectively. The angle between the axis of the baffles and the axis of the barrel body 22 is 30-60 degrees.

[0032] Three groups of baffles are provided in the barrel body 22, and each group of baffles is symmetrically arranged. The three groups of baffles include a first baffle 261, a second baffle 262 and a third baffle 263, wherein the first baffle 261 is located in the second barrel body 222, the second baffle 262 is located between the second barrel body 222 and the third barrel body 223, and the third baffle 263 is located in the third barrel body 223.

[0033] like Figure 3 As shown, in this embodiment, both ends of the first baffle 261, the second baffle 262 and the third baffle 263 are respectively fixed on the inner side surface of the barrel body 22, and one side surface of the first baffle 261 is also fixed on the inner side surface of the barrel body 22. The first baffle 261 is tilted downward toward the center of the barrel body 22, the second baffle 262 is tilted downward toward the outside of the barrel body 22, and the third baffle 263 is tilted downward toward the center of the barrel body 22.

[0034] like Figure 4 As shown, in this embodiment, the two ends of the first baffle 261, the second baffle 262 and the third baffle 263 are respectively fixed on the inner side surface of the barrel body 22, the second baffle 262 is tilted downward toward the outside of the barrel body 22, and the third baffle 263 is tilted downward toward the center of the barrel body 22. The extension lines of the first baffle 261 and the second baffle 262 intersect vertically, and the extension lines of the second baffle 262 and the third baffle 263 intersect vertically. The dry powder mortar falling into the packaging barrel passes through the first baffle 261, the second baffle 262 and the third baffle 263 step by step, with a small drop height, a good buffering effect, and less segregation.

[0035] like Figure 5 As shown, a group of fourth baffles 264 can also be provided in the packaging barrel 2, and the fourth baffles 264 are located in the third barrel body 223. The two ends of the fourth baffles 264 are fixed on the inner side surface of the third barrel body 223 and located above the recessed portion, and the fourth baffles 264 are tilted downward toward the recessed portion.

[0036] The upper surfaces of the first baffle 261, the second baffle 262, the third baffle 263 and the fourth baffle 264 are provided with a plurality of speed reduction bumps, which can reduce the flow rate of the dry mortar, so that the dry mortar can enter the warehouse at a uniform and stable speed, and better ensure the quality of the dry mortar.

[0037] The cross section of the stirring blades 14 is T-shaped, and the stirring blades 14 are evenly spaced in the axial direction of the stirring shaft 13. The stirring blades 14 are arranged in a circular array on the circumferential surface of the stirring shaft 13. The above arrangement of the stirring blades 14 can make the raw materials of the dry mortar more fully stirred in the mixing drum 1 and mixed more evenly.

[0038] The working principle of the anti-segregation packaging device for dry mortar of the present invention is as follows:

[0039] First, various raw materials are fed into the first feed port of the mixing drum 1, and the mixing drum 1 is started for stirring. The horizontally arranged mixing drum 1 can fully stir the dry mortar;

[0040] Next, after stirring, the hatch 12 is opened, and the dry mortar falls into the packaging barrel and is baffled and buffered by the baffle plate to avoid separation of sand and cement and reduce segregation. The dry mortar falls to the bottom of the packaging barrel 2 and fills the concave part until the amount of the dry mortar exceeds the third baffle plate 263;

[0041] Finally, when the amount of dry mortar falling from the packaging barrel 2 reaches a certain amount, the flow valve of the discharge port 24 below the packaging barrel 2 is opened for discharging and packaging. A certain amount of dry mortar is always retained in the packaging barrel 2. A certain amount of dry mortar in the packaging barrel 2 can reduce the falling height of the material in the mixing barrel entering the packaging barrel 2, thereby reducing segregation.

[0042] The anti-segregation packaging device for dry-mixed mortar of the present invention has a horizontally arranged mixing drum that can fully mix various raw materials to form dry-mixed mortar, and a baffle is provided in the packaging barrel below the mixing drum, which has the function of reducing the flow rate of the dry-mixed mortar, effectively preventing the dry-mixed mortar from segregating during the vertical fall process, thereby improving the mixing uniformity of the dry-mixed mortar, ensuring the production quality, reducing the labor of workers, and improving the production efficiency.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
