Description

Technical Field

[0001] This utility model relates to the technical field of mixing devices, and more specifically, to a device for rapid preparation and molding of impermeable reference mortar. Background Technology

[0002] Anti-permeability benchmark mortar is a core reference material in the field of anti-permeability performance testing for building waterproofing projects. Essentially, it serves as a "standard reference" for calibrating anti-permeability testing equipment and determining the anti-permeability performance of other mortars. Its core characteristics are distinct: it must meet stringent requirements such as fixed mix proportions, stable performance, and high density. Furthermore, its preparation process and various performance indicators must strictly adhere to national standards to ensure its authority and reliability as a benchmark.

[0003] Compared to conventional building mortar, anti-seepage benchmark mortar typically requires a smaller quantity per application, but its preparation requirements far exceed those of conventional mortar. On one hand, the accuracy of the proportions must reach extremely high standards; the errors in the amounts of aggregates, cementitious materials, water, and additives must be controlled within a very small range. Any slight deviation can lead to fluctuations in anti-seepage performance, rendering the benchmark meaningless. On the other hand, the requirements for mixing are much more stringent, demanding extremely uniform fusion of materials to avoid problems such as localized moisture concentration, powder clumping, or uneven aggregate distribution. This ensures a dense internal structure of the mortar, eliminating potential seepage channels.

[0004] However, most existing mixing equipment is geared towards large-scale mortar preparation, with its core design focused on balancing mixing rate and basic mixing effect, making it difficult to adapt to the refined requirements of anti-seepage benchmark mortar. Conventional equipment is prone to problems such as material agglomeration and residue buildup on the inner wall of the mixing drum during small-batch mixing: cementitious materials easily absorb water and clump together to form "cement lumps," aggregates may deposit at the bottom of the equipment, and residual material on the inner wall will affect the mixing accuracy of the next batch. These problems directly compromise the uniformity and performance stability of the anti-seepage benchmark mortar, adversely affecting the final test results. Therefore, an anti-seepage mortar preparation device with better mixing performance can be designed. Utility Model Content

Detailed Implementation

[0017] Example The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 -Appendix Figure 7 As shown, the rapid preparation and molding device for anti-seepage reference mortar in this embodiment includes a horizontally arranged mixing tank 10, a feed inlet at the upper end of the mixing tank 10, a discharge port at the lower end of the mixing tank 10, a sealing plate 12 at the discharge port, a first mixing component and a second mixing component horizontally arranged inside the mixing tank 10, and a driving device 40 for driving the first mixing component and the second mixing component to rotate. The lower side wall of the mixing tank 10 is semi-circular. The first mixing component includes a first mixing cylinder 20 with a horizontal cylindrical structure, and the outer wall of the first mixing cylinder 20 is arranged close to the lower side wall of the mixing tank 10. The second mixing component includes a second mixing cylinder 30 with a horizontal cylindrical structure, and the second mixing cylinder 30 is arranged inside the first mixing cylinder 20. Specifically, during use, the raw materials are fed into the mixing tank 10 through the feed inlet. The drive device 40 drives the first and second mixing components to simultaneously mix the raw materials. Since the lower side wall of the mixing tank 10 is semi-circular, the first mixing drum 20 can effectively scrape the raw materials on the bottom wall of the mixing tank 10 and throw them up. The second mixing drum 30 can then mix the raw materials inside the first mixing drum 20. In this way, the raw materials will continuously pass back and forth between the first mixing drum 20 and the second mixing drum 30, which can efficiently mix the powdered materials, effectively avoid clumping, and also prevent the raw materials from sticking to the bottom, resulting in a highly uniform final mixture. The mixed material can be discharged through the discharge port. Furthermore, due to the scraping action of the second mixing drum 30, there is less material residue in the mixing tank 10, making subsequent cleaning easier.

[0018] In this embodiment, the first stirring tank 20 includes a plurality of horizontally arranged first stirring blades 21, a pair of first connecting plates 22 respectively disposed at both ends of the first stirring blades 21, a first sleeve 23 connected to one of the first connecting plates 22, and a second sleeve 24 connected to the other first connecting plate 22; the plurality of first stirring blades 21 are fixedly connected at both ends to the pair of first connecting plates 22, the plurality of first stirring blades 21 are circumferentially distributed, the first stirring blades 21 are disposed near the bottom wall of the mixing tank 10, and the first sleeve 23 and the second sleeve 24 are both rotatably connected to the side wall of the mixing tank 10. The second stirring tank 30 includes a plurality of horizontally arranged second stirring blades 31, a pair of second connecting plates 32 respectively disposed at both ends of the second stirring blades 31, a first drive shaft 33 connected to one of the second connecting plates 32, and a second drive shaft 34 connected to the other second connecting plate 32; the plurality of second stirring blades 31 are fixedly connected at both ends to the pair of second connecting plates 32, the plurality of second stirring blades 31 are circumferentially distributed, the first drive shaft 33 is rotatably disposed in the first sleeve 23, and the second drive shaft 34 is rotatably disposed in the second sleeve 24. Specifically, a first mixing drum 20 is formed by a pair of first connecting plates 22 and multiple first stirring plates 21, which can stir the outer side of the raw material; a second mixing drum 30 is formed by a pair of second connecting plates 32 and multiple second stirring plates 31, which can stir the inner side of the raw material, and the raw material will move back and forth between the first mixing drum 20 and the second mixing drum 30, which can improve the mixing effect. The connection between the first mixing drum 20 and the second mixing drum 30 is achieved by a first drive shaft 33, a second drive shaft 34, a first sleeve 23 and a second sleeve 24. By placing the first drive shaft 33 in the first sleeve 23 and the second drive shaft 34 in the second sleeve 24, the rotation of the first mixing drum 20 and the second mixing drum 30 will not interfere with each other.

[0019] The driving device 40 in this embodiment includes a first driven wheel 41 disposed on the outer wall of the first sleeve 23, a motor 42, a driving wheel 43 disposed on the output shaft of the motor 42, and a first transmission belt 44 for connecting the driving wheel 43 and the first driven wheel 41. Specifically, the motor 42 can drive the first sleeve 23 to rotate through the transmission belt, thereby driving the first stirring tank 20 to rotate.

[0020] The driving device 40 in this embodiment also includes a second driven wheel 45 disposed on the outer wall of the second sleeve 24, a transmission shaft 46 rotatably connected to the outer wall of the mixing tank 10, a transmission wheel 47 disposed on the transmission shaft 46, a second transmission belt 48 for connecting the second driven wheel 45 and the transmission wheel 47, a first gear 49 disposed on the transmission shaft 46, and a second gear 410 disposed on the second drive shaft 34; the first gear 49 and the second gear 410 mesh. Specifically, the motor 42 drives the first mixing drum 20 to rotate, causing the second driven wheel 45 of the second sleeve 24 to rotate, and driving the transmission wheel 47, the transmission shaft 46, and the first gear 49 to rotate through the second transmission belt 48. The first gear 49 drives the second gear 410 to rotate, ultimately driving the second drive shaft 34 and the second mixing drum 30 to rotate. Through this structure, the rotation direction of the first mixing drum 20 is opposite to the rotation direction of the second mixing drum 30, which has a better mixing effect.

[0021] In this embodiment, the mixing tank 10 has a pair of inclined plates 13 at the top, which are V-shaped. One side of the inclined plate 13 is connected to the top of the mixing tank 10 near the feed inlet, and the other side is located near the inner wall of the mixing tank 10. The mixing tank 10 is connected to multiple nozzles 14, which are connected to water inlet pipes 15. The multiple nozzles 14 are all located directly above the inclined plates 13 and pass through the top wall of the mixing tank 10 before being placed inside the mixing tank 10. Specifically, the feed inlet is mainly used to feed powdery materials. Various powdery materials are first fed into the feed inlet and stirred evenly. Then, water is added through the water inlet pipe 15 and the nozzles 14, and the mixing continues. Water is gradually added to the mixing tank 10 through the nozzle 14. The water sprayed from the nozzle 14 flows onto the inclined plate 13, and then flows through the inclined plate 13 to the inner wall of the mixing tank 10. It then flows down the inner wall of the mixing tank 10 and mixes with the powder. During this process, the water can wash down the powder or slurry on the inner wall of the mixing tank 10, so that the raw materials are as little as possible left on the inner wall of the mixing tank 10.

[0022] In this embodiment, a cover plate 11 is provided at the feed inlet.

[0023] In this embodiment, the mixing tank 10 has multiple support legs 16 on its lower side wall.

[0024] In summary, the rapid preparation and molding device for anti-seepage benchmark mortar in this embodiment involves feeding raw materials into the mixing tank 10 through the feed inlet. The drive device 40 drives the first and second mixing components to simultaneously mix the raw materials. Since the lower side wall of the mixing tank 10 is semi-circular, the first mixing drum 20 can effectively scrape the raw materials from the bottom wall of the mixing tank 10 and throw them up. The second mixing drum 30 can then mix the raw materials inside the first mixing drum 20. In this way, the raw materials continuously pass back and forth between the first mixing drum 20 and the second mixing drum 30, which can efficiently mix the powdery materials, effectively avoid clumping, and prevent the raw materials from sticking to the bottom. This results in a highly uniform final mixture. The mixed material can be discharged through the discharge port. Furthermore, due to the scraping action of the second mixing drum 30, there is less material residue in the mixing tank 10, making subsequent cleaning easier.

[0025] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
