[0002] In construction engineering practice, the mixing quality of cement paste plays a decisive role in the final quality of the project. However, existing traditional cement paste mixers have many drawbacks. For example, the conventional design of the mixing blades easily creates dead zones during the mixing process, resulting in incomplete mixing of the cement paste and seriously affecting the stability of the material's properties. Based on the above situation, it is necessary to develop a new type of cement paste mixer, which is of great practical significance for improving the mixing technology of building materials and ensuring project quality. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a paste mixing device, which is conducive to the full mixing of materials, improves the performance stability of paste materials, and thus helps to ensure the quality of the project.

The stirring paddle includes a main rod and blades connected to the main rod. The blades are spirally arranged around the main rod, and the wide surface of the blades is set at a certain angle to the horizontal plane.

[0008] When the stirring paddle rotates, it can squeeze the material in the guide tube downwards, thereby causing the material to circulate inside and outside the guide tube.

[0009] In a preferred embodiment of this utility model, the bottom of the mixing tank is arc-shaped and convex downward.

[0010] In a preferred embodiment of this utility model, the upper end of the blade is located above the guide tube, and the lower end of the blade extends out of the guide tube.

[0011] In a preferred embodiment of this utility model, the top of the mixing tank is provided with a support platform, and a feeding port is provided on one side of the support platform, the feeding port being connected to the mixing tank; the driving mechanism is disposed on the support platform, and the main rod extends into the mixing tank after passing through the support platform.

[0012] Preferably, a feeding component is provided at the feeding port, the bottom plate of the feeding component extends at an inclination, the end of the feeding component outside the mixing tank is higher, and the end of the feeding component inside the mixing tank is lower.

[0013] A preferred embodiment of the present invention further includes a pumping mechanism; the pumping mechanism includes a pumping drive source, a conduit, and a jet pipe; one end of the conduit and the jet pipe are respectively connected to the inlet and outlet of the pumping drive source, the conduit is located inside the mixing tank, and the jet pipe is located outside the mixing tank.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention relates to a cement paste mixing device that employs a spiral and inclined impeller combined with a guide tube design. This allows the impeller to rotate at high speed, driving the material to rotate and mix, while simultaneously exerting a downward compressive force on the material within the guide tube. This results in strong axial and radial thrust, causing the material to circulate within and outside the guide tube. Specifically, driven by the impeller, some material sinks downwards under the thrust, while the rest slowly rises along the guide tube. This creates a highly efficient circulation pattern, ensuring comprehensive and deep integration of various materials, guaranteeing uniform distribution of components in the cement paste, and significantly improving the stability of the material quality.

[0036] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0038] See Figures 1-5 This embodiment discloses a paste mixing device, including a mixing tank 1, a guide cylinder 2, a mixing mechanism 3, a pumping mechanism 5, a base 4, and a control module 6. In this embodiment, the guide cylinder 2 is disposed inside the mixing tank 1, with gaps between the guide cylinder 2 and the inner wall of the mixing tank 1, as well as the bottom of the mixing tank 1, to form a flow channel 7. The mixing mechanism 3 includes a mixing blade and a drive mechanism 303 for rotating the mixing blade, with the mixing blade located within the guide cylinder 2. The mixing blade includes a main rod 302 and blades 301 connected to the main rod 302. The blades 301 are spirally arranged around the main rod 302, and the wide surface of the blades 301 is at a certain angle to the horizontal plane. This can be understood as the wide surface of the blades 301 being inclined. Combined with the spiral structure of the blades 301, the rotation of the blades 301 generates a downward thrust on the material. When the mixing blade rotates, it squeezes the material inside the guide cylinder 2 downwards, thereby causing the material to circulate inside and outside the guide cylinder 2.

[0039] Furthermore, the bottom of the mixing tank 1 in this embodiment is arc-shaped and convex downwards, and can be configured to resemble a spherical structure. This makes the bottom surface of the mixing tank 1 form a smoother guide surface, allowing the material located in the middle of the guide cylinder 2 to be pressed down and diffuse outwards along the arc-shaped bottom, and then gradually rises along the guide channel 7, making the material circulation more regular.

[0040] To further improve the mixing effect of materials, in this embodiment, the upper end of the blade 301 is located above the guide tube 2, and the lower end of the blade 301 extends out of the guide tube 2. This arrangement ensures that the blade 301 completely penetrates the guide tube 2, so that the materials located above and below the guide tube 2 can also be affected by the stirring and compression of the blade 301, thereby allowing the materials in the mixing tank 1 to be fully mixed and form a circulating flow inside and outside the guide tube 2, thus improving the mixing effect of materials.

[0041] Furthermore, the blade 301 in this embodiment can be composed of multiple blades, each extending in a spiral manner, thus facilitating assembly. Alternatively, the blade 301 in this embodiment can also adopt an integral structure, that is, the blade 301 is a continuous blade; such as Figures 1-2 As shown, the bottom of the continuous blade 301 is curved and transitioned, which gives the bottom of the blade 301 a stronger stirring ability.

[0042] In this embodiment, the top of the mixing tank 1 is provided with a support platform 8, and a feeding port is provided on one side of the support platform 8, which is connected to the mixing tank 1. The drive mechanism 303 is mounted on the support platform 8, and the main rod 302 extends into the mixing tank 1 after passing through the support platform 8. The support platform 8 provides a support position for the drive mechanism 303 and other components, facilitating installation and fixation. It also protects the top opening of the mixing tank 1 and prevents splashing. When it is necessary to feed material into the mixing tank 1, the material can be placed through the feeding port.

[0043] Furthermore, in this embodiment, a feeding component 9 is provided at the feeding port. The bottom plate of the feeding component 9 extends at an incline, with the end outside the mixing tank 1 being higher and the end inside the mixing tank 1 being lower. The feeding component 9 facilitates the feeding of materials.

[0044] The pumping mechanism 5 in this embodiment includes a pumping drive source 503, a conduit 501, and a jet pipe 502; one end of the conduit 501 and the jet pipe 502 are respectively connected to the inlet and outlet of the pumping drive source 503, the conduit 501 is located inside the mixing tank 1, and the jet pipe 502 is located outside the mixing tank 1.

[0045] Furthermore, the conduit 501 extends along the inner wall of the mixing tank 1, and the feed end of the conduit 501 is located below the guide tube 2; the conduit 501 has multiple through holes 505 near the feed end. In this embodiment, the pumping drive source 503 is also mounted on the support platform 8. To better fix the position of the conduit 501, a buckle or fixing ring can be provided on the inner wall of the mixing tank 1 to lock the position of the conduit 501, thus preventing the conduit 501 from being affected by material flow. The through holes 505 on the conduit 501 allow material to enter better from the feed end, which helps to prevent the conduit 501 from becoming clogged.

[0046] The pumping mechanism 5 in this embodiment also includes a flow control valve 504, which is electrically connected to the pumping drive source 503. The flow control valve 504 can utilize an advanced smart chip, capable of controlling the outflow of cement slurry with extremely high precision according to a preset program. Simultaneously, a casting nozzle with a special atomization design can be installed at the discharge end of the spray pipe 502 in this embodiment. For example, the surface of the casting nozzle can be covered with micron-level fine nozzles arranged in a special array. When the cement slurry passes through the nozzle, under pressure, it is dispersed into extremely fine droplets and evenly sprayed into the mold. Through the coordinated operation of this series of precision components, the cement slurry material is evenly poured, ensuring uniform distribution within the mold.

[0047] The base 4 in this embodiment includes a mobile platform 401, several limiting members 402, and several casters 403. Each limiting member 402 is disposed on the mobile platform 401 and encloses a limiting area. The mixing tank 1 is disposed on the mobile platform 401 and located within the limiting area. Each caster 403 is fixed to the bottom surface of the mobile platform 401, and one or more casters 403 have a brake 404 structure. The mobile platform 401 provides a support platform for the mixing tank 1. In particular, the bottom of the mixing tank 1 in this embodiment is arc-shaped. By utilizing the limiting members 402 on the mobile platform 401 in this embodiment, the mixing tank 1 can be better kept in an upright position. At the same time, the casters 403 facilitate the movement of the mobile platform 401.

[0048] The control module 6 in this embodiment is used to control the drive mechanism 303 and the pumping drive source 503. The control module 6 is electrically connected to the drive mechanism 303 and the pumping drive source 503. The control module 6 in this embodiment includes a chassis, a display screen, buttons, etc., and can also be equipped with a wireless connection module, such as Bluetooth or Wi-Fi, to achieve remote control. Through the control module 6, the pumping drive source 503 and the drive mechanism 303 can be controlled more conveniently; for example, the power output, forward and reverse rotation can be changed according to the site conditions. In this embodiment, the pumping drive source 503 and the drive mechanism 303 can be motors.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
