Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing, and more specifically to a concrete mixing device for construction engineering. Background Art

[0002] Construction engineering refers to the engineering activities that use engineering technology and scientific knowledge to rationally plan, design, build and maintain land, underground space and above-ground space under certain economic conditions and in accordance with certain design, construction and management requirements. Construction engineering includes various engineering projects such as house construction, road construction, bridge engineering, water conservancy engineering, urban planning, etc.

[0003] A concrete mixing device is a device used for mixing and stirring concrete. A concrete mixing device is usually composed of a mixing barrel, a mixer, a transmission device, a support device, etc. In construction projects, a concrete mixing device is used to mix raw materials such as cement, sand, and aggregates to form concrete for pouring floor slabs, columns, walls, and other building structures.

[0004] The existing concrete mixing devices for construction projects still have the following problems: when the existing concrete mixing devices are used to mix concrete, the required materials are mostly directly poured into the mixing barrel and the concrete is mixed by rotating the mixing rod. However, during the mixing process, the cement in the concrete will release gas during the hydration reaction, and these gases will form bubbles in the concrete. Or, during the mixing process, the concrete is polluted by air, which will also cause bubbles to appear in the concrete. These bubbles will have a certain impact on the compactness and strength of the subsequent concrete, which brings many inconveniences to the subsequent use;

[0005] Secondly, when mixing concrete in the cold winter, the fluidity of low-temperature concrete will deteriorate, and stratification and uneven mixing will easily occur. In addition, since only a single stirring rod is used to stir the cement in one direction, the stirring effect is not ideal, and it takes a longer time to stir and mix it. This not only affects the quality of the concrete but also reduces its mixing efficiency, causing great trouble to its use.

[0006] In view of this, we propose a concrete mixing device for construction engineering. Utility Model Content

[0029] In some embodiments, the vacuum pump 220 can discharge the gas inside the mixing barrel 200, effectively reducing the bubbles generated inside the concrete due to mixing.

[0030] The output end of the stirring motor 230 extends to the inside of the stirring barrel 200 and is connected to a stirring assembly. The stirring assembly includes a support plate 231 . A fixed heating sleeve 260 is sleeved on the outer wall of the stirring barrel 200 .

[0031] Specifically, a discharge pump 250 is provided at the bottom of the mixing barrel 200, and a discharge pipe is connected to the output end of the discharge pump 250 to facilitate the discharge of the mixed concrete.

[0032] Furthermore, an electric heating tube 261 electrically connected to the temperature controller 120 is provided inside the fixed heating jacket 260, and an insulation jacket 270 is sleeved on the outer wall of the fixed heating jacket 260, so as to better ensure the quality of concrete mixing in relatively cold weather.

[0033] Furthermore, a sealing cover 241 is provided on the top of the feed hopper 240, and a rotating handle is provided on the top of the sealing cover 241 to facilitate sealing of the mixing barrel 200 and reduce the entry of external air to cause more bubbles to appear inside the concrete.

[0034] Furthermore, a support plate 232 and an ultrasonic vibration rod 239 are provided at the bottom of the support plate 1 231. The ultrasonic vibration rod 239 is electrically connected to the ultrasonic generator 130. The support plate 232 is in contact with the inner wall of the mixing barrel 200, so as to facilitate ultrasonic vibration of the concrete, thereby improving its mixing efficiency and releasing bubbles.

[0035] In some embodiments: the ultrasonic vibrator 239 generally includes a vibrating head, a vibrating device, a housing, and a connecting line. The ultrasonic generator 130 generally includes a driving circuit, a control panel, a power interface, and an output interface. The ultrasonic vibrator 239 and the ultrasonic generator 130 are generally used in conjunction with each other. The ultrasonic generator 130 generates a high-frequency electrical signal to drive the vibrating head of the ultrasonic vibrator 239 to generate ultrasonic waves, thereby realizing the application of ultrasonic waves. Secondly, the ultrasonic vibrator 239, the rotating motor 1 233, and the rotating motor 2 236 are all connected to the outside by electric wires via a rotating joint to avoid winding.

[0036] It is worth mentioning that a rotating motor 233 and a rotating motor 236 are arranged inside the multiple support plates 231, and the output ends of the rotating motor 233 and the rotating motor 236 are respectively connected to the stirring rod 1 234 and the stirring rod 2 237, and the circumferential outer walls of the stirring rod 1 234 and the stirring rod 2 237 are respectively connected to the stirring support rod 1 235 and the stirring support rod 2 238, so as to facilitate better mixing of the concrete.

Needless to say, the content protected by the utility model does not involve improvements to the internal structure and methods.

[0040] Working principle: First, when concrete needs to be stirred and mixed, the concrete raw materials can be put into the feed hopper 240, and then the mixing barrel can be sealed with the sealing cover 241. Then, the concrete can be stirred and mixed with the stirring rod 1 234 and the stirring rod 238. During the stirring and mixing process, the air inside the mixing barrel 200 is extracted by the vacuum pump 220, and the bubbles inside the concrete are vibrated and released in conjunction with the ultrasonic vibration rod 239, which effectively helps the concrete to be more evenly distributed, reduces the pores and defects in the concrete, and improves the quality of the concrete. Secondly, in the relatively cold winter When mixing concrete, the temperature controller 120 can be used to control the temperature of multiple electric heating tubes 261, which in turn acts on the concrete being mixed, so that the mixing quality of the concrete can be better ensured. During the mixing process, the mixing assembly will be driven by the mixing motor 230 to perform horizontal mixing. In this process, the rotating motor 1 233 and the rotating motor 2 236 can drive the mixing rod 1 234 and the mixing rod 2 237 to perform longitudinal rotation mixing on the concrete, which effectively improves the uniformity of the mixing, and can better reduce the time loss required for mixing, and effectively improves the mixing efficiency.
