Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a grouting device for building construction. Background Technology

[0002] In the construction industry, the slurry mixing process is a crucial step in determining the performance of building materials such as concrete and waterproof coatings. Currently, the small-scale slurry mixers commonly used on construction sites are typically equipped with a single-shaft mixing system, consisting of a single mixing shaft and several spiral or paddle-type mixing components arranged along the shaft. This traditional structure exhibits significant limitations in practical applications:

[0003] First, the material is limited to a linear motion trajectory with single-axis rotation, forming only a unidirectional vortex and lacking multi-dimensional shear force and convective mixing effects, resulting in significant material stratification. Second, high-viscosity slurries are prone to generating a viscous boundary layer during mixing. Material in the container wall area adheres to the inner wall due to centrifugal force, forming a "dead zone." Conventional mixing blades struggle to penetrate this area's flow field, severely restricting construction efficiency and potentially causing quality problems such as material segregation. Therefore, further improvements are needed. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a grouting device for building construction.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a slurry making equipment for building construction, including: a workbench, a slurry making tank, several mixing mechanisms and an internal scraping mechanism;

[0006] The workbench is located above the pulping tank; the stirring mechanism and the internal scraping mechanism are installed on the workbench;

[0007] The stirring mechanism includes a stirring rod, a stirring drive assembly, and a stirring paddle; the stirring paddle extends into the pulping tank; several stirring mechanisms are staggered on the worktable;

[0008] The internal scraping mechanism includes an internal scraping center rod, an internal scraping drive assembly, and a scraper assembly; the scraper assembly is installed on the internal scraping center rod and includes a side scraper attached to the inner wall of the pulping tank; the internal scraping center rod and the stirring rod are axially offset.

[0009] Optionally, the inner scraper center rod is located at the center of the pulping tank; a plurality of the stirring rods are evenly arranged circumferentially around the outer periphery of the inner scraper center rod.

[0010] Optionally, the scraper assembly further includes a bottom scraper, which is attached to the bottom wall of the pulping tank; one end of the bottom scraper is connected to the inner scraper center rod, and the other end is connected to the side scraper.

[0011] Optionally, multiple side scrapers are provided; annular top fixing rings are welded to the top of the multiple side scrapers; the axis of the top fixing rings coincides with the axis of the inner scraper center rod.

[0012] Optionally, the bottom scraper and side scraper are provided with detachable scraper blades.

[0013] Optionally, the scraper blade is bolted to the bottom scraper or the side scraper.

[0014] Optionally, the worktable is equipped with a lifting and movable device.

[0015] The beneficial effects of this invention are as follows: Multiple staggered stirring mechanisms form a three-dimensional turbulent flow field with opposite rotation, causing the material to generate a composite shear gradient in the radial and axial directions, effectively eliminating the laminar flow phenomenon of traditional single-axis stirring and improving mixing uniformity. The side scraper maintains a dynamic gap with the inner wall of the pulping tank, synchronously breaking down the viscous boundary layer through a planetary motion trajectory, allowing the material adhering to the wall to participate in the main mixing flow and eliminating dead zones in volume utilization. In this invention, the staggered movement of the stirring paddle and scraper assembly forms a complementary stirring combination, effectively improving the uniformity of pulping and mixing, and enhancing the quality of the slurry.

[0025] Example

[0026] Reference Figure 1 The present invention proposes a slurry making equipment for building construction, comprising: a workbench 10, a slurry making tank 20, several mixing mechanisms 30 and an internal scraping mechanism 40;

[0027] The workbench 10 is located above the pulping tank 20; the mixing mechanism 30 and the internal scraping mechanism 40 are installed on the workbench 10;

[0028] The mixing mechanism 30 includes a mixing rod 31, a mixing drive assembly 32, and a mixing paddle 33; the mixing paddle 33 extends into the pulping tank 20; several mixing mechanisms 30 are staggered on the workbench 10.

[0029] The inner scraping mechanism 40 includes an inner scraping center rod 41, an inner scraping drive assembly 42, and a scraper assembly 43; the scraper assembly 43 is installed on the inner scraping center rod 41 and includes a side scraper 431 attached to the inner wall of the pulping tank 20; the inner scraping center rod 41 and the stirring rod 31 are axially offset.

[0030] In this invention, multiple staggered stirring mechanisms 30 form a three-dimensional turbulent flow field rotating in opposite directions, causing the material to generate a composite shear gradient in the radial and axial directions. This effectively eliminates the laminar flow phenomenon of traditional single-axis stirring, improving the mixing uniformity. The side scraper 431 maintains a dynamic gap with the inner wall of the pulping tank 20, and synchronously breaks down the viscous boundary layer through a planetary motion trajectory, allowing the wall-mounted material to participate in the main mixing flow and eliminating dead zones in volume utilization. In this invention, the staggered movement of the stirring paddle 33 and the scraper assembly 43 forms a complementary stirring combination, effectively improving the uniformity of pulping and mixing, and enhancing the quality of the slurry.

[0031] In this embodiment, the inner scraper center rod 41 is located at the center of the pulping tank 20; a plurality of stirring rods 31 are evenly arranged around the outer periphery of the inner scraper center rod 41. The evenly distributed stirring rods 31 form an array of equal-intensity vortices, and the symmetrical layout reduces the vibration amplitude of the equipment and improves the stability of the equipment operation.

[0032] In this embodiment, the scraper assembly 43 further includes a bottom scraper 432, which is attached to the bottom wall of the pulping tank 20. One end of the bottom scraper 432 is connected to the inner scraper center rod 41, and the other end is connected to the side scraper 431. The bottom scraper 432 fits the bottom of the tank with gaps, forming an L-shaped cleaning interface with the side scraper 431. The bottom scraper 432 can cut the bottom wall of the pulping tank 20, and also serves as a bottom connection structure, connecting the side scraper 431 at the bottom, so that the scraper center rod can drive the side scraper 431 to rotate synchronously.

[0033] Furthermore, multiple side scrapers 431 are provided; annular top fixing rings 433 are welded to the top of the multiple side scrapers 431; the axis of the scraper center rod 41 is coincident with the axis of the top fixing ring 433. This ensures the uniformity of the gap between the scraper assembly and the barrel wall, making the scraper assembly 43 a more stable overall structure, allowing for stable rotation, and preventing the side scrapers 431 from deforming or swaying.

[0034] In this embodiment, the bottom scraper 432 and the side scraper 431 are equipped with detachable scraper blades 434. By replacing the scraper blades 434 with blades of different hardness, it can be adapted to a variety of material systems from mortar to epoxy resin, and it is also convenient to change or replace damaged blades.

[0035] Specifically, scraper 434 is bolted to bottom scraper 432 or side scraper 431.

[0036] In this embodiment, the workbench 10 is equipped with a lifting mechanism. The lifting mechanism allows the scraper assembly to be raised to a position above the bucket opening to remove or place paint buckets, or to add raw materials into the paint buckets.

[0037] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
