Description

Technical Field

[0001] This utility model belongs to the field of construction equipment technology, specifically relating to a circulating water-saving concrete mixing device. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction. A mixing device is required when mixing concrete.

[0003] Existing concrete mixing equipment for construction still has some shortcomings. After mixing concrete, the inside of the equipment needs to be cleaned in time to prevent the concrete from drying and solidifying on the inner wall of the equipment, which is difficult to clean. Currently, when rinsing the inside of the equipment, the water used for rinsing is directly discharged as wastewater, which wastes water resources and does not meet the standards of energy-saving construction. Therefore, we propose a circulating water-saving concrete mixing equipment. Utility Model Content

[0004] The purpose of this invention is to propose a circulating water-saving concrete mixing device to address the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a circulating water-saving concrete mixing device, including a mixing drum, a support leg at the bottom of the mixing drum for supporting the mixing drum, and a connecting pipe connected to the bottom of the drum. An annular groove is opened on the inner wall of the connecting pipe, and an elbow for discharging concrete from the mixing drum is installed on the connecting pipe. A rotating ring is provided on the elbow and rotates with the annular groove, so that the elbow can rotate in the connecting pipe. A motor is installed at the top of the mixing drum, and a mixing component placed in the mixing drum is installed on the rotating end of the motor. A water tank is provided below the mixing drum, and a water pump is also provided at the top of the mixing drum. A water outlet pipe extending into the mixing drum is installed at the water outlet end of the water pump, and a water inlet pipe extending into the water tank is installed at the water inlet pipe of the water pump. The water pump draws water from the water tank into the mixing drum, which is used to flush the concrete inside the mixing drum under the action of the mixing component, and the water returns to the water tank.

[0006] Furthermore, a valve is installed on the elbow. When the valve is closed, it prevents the discharge of concrete or water used for cleaning the mixing drum.

[0007] Furthermore, the support legs are L-shaped, and the water tank is placed between and connected to the two support legs. The water tank and the support legs together support the mixing drum.

[0008] Furthermore, the bottom of the water inlet pipe is placed in the middle of the water storage tank.

[0009] Furthermore, the stirring assembly includes a rotating rod connected to the rotating end of the motor, on which a stirring rod is mounted.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0011] (1) The water pump draws water from the storage tank into the mixing drum. Driven by the mixing components, the water is used to flush the concrete inside the mixing drum and return the water to the storage tank, thus realizing the secondary use of wastewater, effectively saving water resources and reducing costs.

[0018] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-4The present invention provides a technical solution: a circulating water-saving concrete mixing device, including a mixing drum 1, the bottom of the mixing drum 1 is conical, and two corresponding support legs 2 are fixedly connected to the bottom wall. The support legs 2 are L-shaped. A water tank 11 is provided below the mixing drum 1. The water tank 11 is placed between the two support legs 2 and connected to them, so that the water tank 11 and the support legs 2 jointly support the mixing drum 1.

[0020] The bottom of the mixing drum 1 is fixedly connected to a connecting pipe 6, which is connected to it. The inner wall of the connecting pipe 6 has an annular groove, and an elbow 7 is installed on the connecting pipe 6. The outer wall of the elbow 7 is fixedly connected to a rotating ring 8 placed in the annular groove.

[0021] The elbow 7 is rotatable on the connecting pipe 6, and one end wall of the water tank 11 is placed below the connecting pipe 6. By rotating the elbow 7 on the connecting pipe 6, the port of the elbow 7 can be placed above the water tank 11 or rotated to the side facing away from the water tank 11.

[0022] A valve 9 is installed on the elbow 7. When the valve 9 is closed, the concrete or water used to clean the mixing drum 1 is blocked from being discharged. When the valve 9 is opened, the concrete or water in the mixing drum 1 can be discharged.

[0023] A motor 4 is installed on the top of the mixing drum 1. A mixing assembly 5 is placed in the mixing drum 1 on the rotating end of the motor 4. The mixing assembly 5 includes a rotating rod 12 connected to the rotating end of the motor 4. A mixing rod 13 is installed on the rotating rod 12. The mixing assembly 5 is electrically driven by the motor 4 to rotate, so that the mixing rod 13 mixes the concrete or water in the mixing drum 1.

[0024] A water pump 10 is installed on the top of the mixing drum 1. A water outlet pipe is installed at the water outlet end of the water pump 10, which extends into the mixing drum 1. A water inlet pipe is installed at the water inlet pipe of the water pump 10, which extends into the water storage tank 11. The bottom end of the water inlet pipe is located in the middle of the water storage tank 11.

[0025] Water is drawn from the water tank 11 by the water pump 10 along the inlet pipe and then enters the mixing drum 1 along the outlet pipe to add water for concrete mixing or to mix the rinsing water in the mixing drum 1.

[0026] In summary, when using this energy-saving construction device, concrete and water are injected into the mixing drum 1 through the feed inlet. The motor 4 is started, which drives the rotating rod 12 to rotate, so that the mixing rod 13 mixes the concrete in the mixing drum 1. After the mixing is completed, the motor 4 is stopped, the elbow 7 is rotated so that its end faces away from the water tank 11, and the valve 9 is opened. The concrete is discharged through the elbow 7 under its own weight.

[0027] Then close valve 9, rotate elbow 7 to position the port above water tank 11, inject water into mixing drum 1 along feed hopper 3, then start motor 4, stirring rod 13 stirs the water in mixing drum 1, the water forms a vortex under the drive of stirring rod 13, flushing mixing drum 1 and washing away the concrete adhering to the inner wall of mixing drum 1.

[0028] Turn off motor 4 and open valve 9. Water carrying the washed-off concrete enters along bend 7 and flows into water tank 11, completing the rinsing of mixing drum 1.

[0029] After sedimentation, the concrete settles to the bottom of the water tank 11, so that the water pump 10 can draw water from the water tank 11 and inject it into the mixing drum 1 for mixing concrete raw materials or rinsing the mixing drum 1.

[0030] This enables the reuse of wastewater, thereby effectively saving water resources and reducing costs.
