Description

Technical Field

[0001] This utility model relates to the technical field of mortar production equipment, and in particular to a lightweight building mortar mixing device. Background Technology

[0002] Lightweight building mortar, as a new type of building material, is increasingly widely used in building energy conservation and decoration projects due to its advantages such as low density and good thermal insulation performance. In the preparation process of lightweight building mortar, the mixing process is the core step—cement, lightweight aggregates (such as expanded perlite and ceramsite), admixtures, and water must be thoroughly mixed in a specific ratio to ensure uniform dispersion of each component. Because lightweight aggregates have low density and low strength, they are prone to breakage or floating during mixing, leading to material separation and poor quality lightweight building mortar. Therefore, there is an urgent need for a lightweight building mortar mixing device to solve these problems. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a lightweight building mortar mixing device, which solves the technical problems of uneven mixing and poor mixing quality in the production process of lightweight building mortar.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A lightweight building mortar mixing device includes: a barrel body with an open top and a cover body. The barrel body is provided with a cavity, and the bottom of the barrel body is provided with a discharge port, which communicates with the cavity body. The cover body is detachably installed at the upper opening of the barrel body. A stirring assembly is installed inside a cavity. The stirring assembly includes a stirring shaft that is horizontally mounted on the barrel. The stirring shaft is provided with a spiral blade and a plurality of stirring plates. The spiral blade extends spirally along the axial direction of the stirring shaft, and the plurality of stirring plates are located on the outer edge of the spiral blade. The stirring plates are mounted on the stirring shaft via connecting rods. A driving device, wherein the driving device is used to drive the stirring shaft to rotate; An opening and closing assembly is used to open and close the discharge port.

[0005] Based on the above structure, the principle of the lightweight building mortar mixing device is as follows: When lightweight building mortar needs to be mixed, firstly, open the cover and put the lightweight building mortar raw material into the cavity through the opening at the top of the bucket; then, start the drive device to drive the mixing shaft to rotate. During the rotation of the mixing shaft, the spiral blades push and mix the lightweight building mortar raw material axially along the mixing shaft, so that the lightweight building mortar raw material circulates along the axial direction of the mixing shaft to ensure uniform mixing. When the outer mixing blades rotate, they can radially shear and tumble the lightweight building mortar raw material in the cavity, further making the lightweight building mortar raw material evenly mixed. They can also shear and tumble the lightweight building mortar raw material in the inner edge area of ​​the bucket where the spiral blades are not directly affected, realizing the function of radial mixing and eliminating dead corners at the edges, ensuring the mixing quality; after the mixing is completed, open the discharge port at the bottom through the opening and closing component. The continuously rotating spiral blades will push the evenly mixed lightweight building mortar towards the discharge port to achieve rapid and thorough discharge.

[0006] Furthermore, in a lightweight building mortar mixing device of this application, the inner wall of the cavity is provided with a limiting edge, which is located at the upper opening of the barrel and extends circumferentially along the barrel. As a preferred embodiment of this application, when the cover is closed, its edge can abut against the upper surface of the limiting edge, vertically limiting the cover and preventing it from moving excessively downwards into the cavity, thus ensuring the stability and positional accuracy of the cover.

[0007] Furthermore, in a lightweight building mortar mixing device of this application, the cover is hinged to the barrel, and a first linear drive device is hinged to the outer wall of the barrel. The movable end of the first linear drive device is hinged to the end of the cover away from the hinge. As a preferred embodiment of this application, the hinged design of the two ends of the first linear drive device in the lightweight building mortar mixing device of this application can eliminate the "additional bending moment" when the cover rotates, and avoid the lateral force generated by the movable end of the first linear drive device due to trajectory mismatch when the cover rotates, which could cause the movable end of the first linear drive device to bend or break. Moreover, during the mixing process, the first linear drive device can lock the cover at the upper opening of the barrel to prevent safety accidents caused by accidental opening.

[0008] Furthermore, in a lightweight building mortar mixing device of this application, several connecting rods are spaced apart along the axial direction of the mixing shaft, with adjacent pairs of connecting rods arranged perpendicular to each other. As a preferred embodiment of this application, the connecting rods and mixing blades work together to force the lightweight building mortar raw materials to continuously change their direction of movement within the cavity, greatly improving the uniformity and efficiency of mixing; moreover, the staggered directions of adjacent mixing blades can partially cancel out the radial force experienced by the mixing shaft during rotation, resulting in smoother operation and reduced vibration.

[0009] Furthermore, in a lightweight building mortar mixing device of this application, a set of wing plates is provided on the outer wall of the connecting rod, and the set of wing plates is evenly spaced along the circumference of the connecting rod. As a preferred embodiment of this application, when the mixing shaft rotates, the wing plates shear, divide, and push the lightweight building mortar raw materials passing through the connecting rod, thereby enhancing the mixing effect of the lightweight building mortar raw materials and improving the mixing uniformity; in addition, the wing plates also serve to improve the rigidity of the connecting rod and prevent the connecting rod from deforming during long-term use.

[0010] Furthermore, the lightweight building mortar mixing device of this application further includes: a frame, the barrel being mounted on the frame, a pair of bearing seats being provided on the frame, the pair of bearing seats being respectively sleeved on the mixing shaft, and a drive device being mounted on the frame, the drive device being drively connected to the mixing shaft. As a preferred embodiment of this application, the lightweight building mortar mixing device of this application provides a stable mounting base for the barrel and the mixing shaft, and the pair of bearing seats are used to reduce the frictional resistance when the mixing shaft rotates and limit the radial runout of the mixing shaft, ensuring stability during mixing.

[0011] Furthermore, in this application, a lightweight building mortar mixing device includes an opening and closing assembly comprising: a valve seat, a valve plate, and a second linear drive device. The valve seat is installed at the discharge port, the valve plate is slidably disposed within the valve seat, and the second linear drive device is installed on the outer wall of the tank, with its movable end connected to the valve plate. As a preferred embodiment of this application, the lightweight building mortar mixing device allows for adjustment of the sliding distance of the valve plate via the second linear drive device to control the opening degree of the discharge port, thereby adjusting the discharge speed of the lightweight building mortar and ensuring a smooth discharge process.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects: The purpose of this invention is to provide a lightweight building mortar mixing device. Through the synergistic action of the spiral blades and mixing plates in the mixing component, the axial circulation and radial shearing tumbling of the lightweight building mortar raw materials are realized, effectively eliminating mixing dead zones and ensuring uniform mixing. At the same time, the discharge speed is controlled by the opening and closing component to achieve fast and thorough discharge. Furthermore, the stable installation of the cover and the smooth operation of the drive device improve the overall operational safety and mixing efficiency. Attached Figure Description
