Description

Technical Field

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

[0002] Traditional concrete mixing equipment struggles to maintain mixing efficiency and quality under extreme temperature conditions. At extremely high temperatures, the concrete evaporates moisture too quickly during mixing, leading to slump loss, shortened setting time, and increased susceptibility to cracking. At extremely low temperatures, the concrete's fluidity decreases, aggregates and cement paste easily separate, resulting in uneven mixing and slow strength development.

[0003] Due to the aforementioned drawbacks, the existing technology uses external equipment (such as heating blankets or air coolers) to regulate the temperature of the stirring device, which has the disadvantages of high energy consumption, slow response, and difficulty in working in coordination with the stirring equipment.

[0004] Therefore, it is urgent to research and develop a concrete mixing device for construction projects that is suitable for extreme temperature environments to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a concrete mixing device for construction engineering, which is suitable for use in extreme temperature environments and improves its applicability.

[0006] To achieve the above objectives, this utility model provides a concrete mixing device for construction engineering, the specific implementation of which is as follows:

[0007] A concrete mixing device for construction engineering includes a mixing tank. A heat-conducting copper pipe is provided on the inner peripheral wall of the mixing chamber inside the mixing tank. The heat-conducting copper pipe extends from the top of the mixing chamber to the bottom of the mixing chamber, and the end of the heat-conducting copper pipe extends from the top of the mixing chamber to the outside of the mixing tank to connect to an external temperature control component.

[0008] The stirring chamber is equipped with a stirring assembly, the stirring blades of the stirring assembly are filled with a heat-conducting medium, and a phase-changing material filling layer is provided between the inner peripheral wall of the stirring chamber and the outer peripheral wall of the stirring tank.

[0009] This utility model discloses a concrete mixing device for construction engineering. Compared with the prior art, it features a heat-conducting copper pipe installed on the inner circumferential wall of the mixing tank, connected to an external temperature control component. A heat-conducting medium is embedded in the mixing blades of the mixing component, and a phase-change material filling layer is placed between the inner circumferential wall of the mixing chamber and the outer circumferential wall of the mixing tank. When used in extreme temperature environments, the phase-change material filling layer slows down the temperature rise inside the mixing tank by absorbing heat or slows down the temperature drop by releasing heat, thereby mitigating the influence of external ambient temperature on the internal temperature of the mixing tank. Furthermore, the heat-conducting medium on the mixing blades enhances the heat transfer between the blades and the concrete. Combined with the temperature control of the liquid entering the heat-conducting copper pipe by the external temperature control component, the mixing temperature inside the mixing chamber can be adjusted. This device is suitable for mixing at appropriate temperatures under extreme ambient temperatures, thus improving the applicability of the concrete mixing device.

[0010] In some embodiments, the mixing tank includes an outer shell and an inner shell, which are connected to each other to form a cavity, and the phase-changing material filling layer is provided in the cavity.

[0011] By configuring the mixing tank into a structure where an outer shell and an inner shell are connected to form a cavity, a phase-changing material filling layer is formed by filling the cavity with phase-changing material.

[0012] In some embodiments, the inner peripheral wall of the inner shell is provided with a wear-resistant and corrosion-resistant metal layer, and the inner peripheral wall of the outer shell is provided with a heat-insulating foam layer.

[0013] By setting a wear-resistant and corrosion-resistant metal layer on the inner circumferential wall of the inner shell, the service life of the mixing tank is improved, and a heat-insulating foam layer is set on the inner circumferential wall of the outer shell to slow down the temperature change inside the mixing chamber.

[0014] In some embodiments, a temperature sensor is provided inside the stirring chamber, and the temperature sensor is electrically connected to the external temperature control component.

[0015] By installing a temperature sensor inside the mixing chamber, which is electrically connected to an external temperature control component, the mixing temperature of the mixing chamber is monitored in real time and fed back to the external temperature control component so that the mixing temperature of the mixing chamber can be adjusted in a timely manner.

[0016] In some embodiments, the stirring assembly includes a stirring shaft, a stirring motor, and stirring blades. The stirring motor is located outside the stirring chamber, one end of the stirring shaft is connected to the stirring motor, and the other end extends into the stirring chamber. The stirring blades are located on the outer wall of the stirring shaft.

[0017] By employing a mixing motor to drive the mixing shaft to rotate and drive the mixing blades to mix the concrete, the stability of concrete mixing is improved.

[0018] In some embodiments, the stirring blade has a hollow interior forming a accommodating cavity, and the heat-conducting medium is disposed within the accommodating cavity.

[0019] The heat conduction efficiency of the stirring blades is improved by placing a heat-conducting medium inside the hollow cavity of the stirring blades.

[0020] In some embodiments, the heat-conducting medium is water or heat-conducting oil.

[0021] By using water or heat transfer oil as the heat transfer medium, the heat transfer effect of the mixing blades on the concrete is ensured.

[0022] In some embodiments, the external temperature control component includes a PLC controller, a thermoelectric cooler, a cooling pipe, and a heating pipe. The PLC controller is electrically connected to the temperature sensor. The cooling pipe and the heating pipe are arranged in parallel. The outlets of both the cooling pipe and the heating pipe are connected to the inlet of the heat-conducting copper pipe. The inlets of both the cooling pipe and the heating pipe are connected to a water supply source. The thermoelectric cooler is connected to a cooling metal and a heating metal. The cooling metal is disposed inside the cooling pipe, and the heating metal is disposed inside the heating pipe. Both the cooling pipe and the heating pipe are provided with control valves electrically connected to the PLC controller.

[0023] By using a PLC controller to receive temperature information from a temperature sensor, the operation of the thermoelectric cooler is controlled to select and open the control valve on the cooling or heating pipe to connect it to the heat-conducting copper pipe, thereby transporting liquid and regulating the temperature inside the stirring chamber, thus improving the convenience and intelligence of temperature regulation.

[0024] In some embodiments, the top of the mixing tank is provided with a top cover, the top cover is provided with an exhaust channel, the exhaust channel penetrates the top cover and connects the mixing chamber with the external environment, and the mixing motor is located on the top cover.

[0025] By installing a top cover on the top of the mixing tank, foreign objects are prevented from entering the mixing chamber and the temperature inside the mixing chamber is prevented from being lost during the mixing process. In addition, an exhaust channel is installed on the top cover to prevent the gas from colliding and causing an explosion due to the sealing of the mixing chamber.

[0026] Based on the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0027] By installing heat-conducting copper pipes on the inner circumferential wall of the mixing tank, which are connected to an external temperature control component, and embedding a heat-conducting medium inside the mixing blades of the mixing component, and placing a phase-change material filling layer between the inner circumferential wall of the mixing chamber and the outer circumferential wall of the mixing tank, the mixing tank can be used in extreme temperature environments. On the one hand, the heat absorption of the phase-change material filling layer slows down the temperature rise inside the mixing tank, or the heat release slows down the temperature drop inside the mixing tank, thereby mitigating the influence of the external ambient temperature on the internal temperature of the mixing tank. On the other hand, the heat-conducting medium on the mixing blades enhances the heat transfer of the mixing blades to the concrete. Combined with the temperature control of the external temperature control component to control the temperature of the liquid entering the heat-conducting copper pipes, the mixing temperature inside the mixing chamber can be regulated. This design is suitable for mixing at appropriate temperatures under extreme ambient temperatures, thus improving the applicability of the concrete mixing device. Attached Figure Description
