Description

Technical Field

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

[0002] Concrete mixing plants are an important component of concrete production lines. They mix powder and liquid materials to form concrete, which is then transported to subsequent processing units.

[0003] Currently, concrete mixing plants employ a fixed design, processing concrete in a fixed location and unable to move during operation. While this meets basic requirements, it presents significant limitations in terms of flexibility and applicability. Furthermore, current concrete mixing plants rely on traditional manual weighing methods to calculate the weight of each raw material. This traditional method results in imprecise control of the powder-to-water ratio, affecting concrete quality and potentially the performance of the final product. It also suffers from high labor costs and low production efficiency. Utility Model Content

[0033] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1 As shown in the figure, the present invention proposes a mixing device for concrete processing, which includes a support assembly 1, a water supply assembly 2, a mixing assembly 3, a control unit 4, and a discharge assembly 5.

[0035] like Figure 2 As shown, the support assembly 1 includes a support box 11 and a movable chassis 12. The movable chassis 12 includes four sets of moving units respectively disposed at the four corners of the bottom end of the support box 11. Each moving unit includes a base plate 121, rollers 123, a connecting shaft, and two connecting plates 122. The top end of the base plate 121 is connected to the bottom end of the support box 11. The two connecting plates 122 are arranged parallel to each other in the vertical direction, and the top ends of the two connecting plates 122 are connected to the bottom end of the base plate 121. The bottom ends of the two connecting plates 122 are connected by the connecting shaft. The rollers 123 are sleeved on the connecting shaft and rotatably connected to the connecting shaft. The rollers 123 drive the support box 11 to move on the horizontal plane. Therefore, the mixing device supports mobile concrete processing. At the same time, the mixing device has a small footprint and has good flexibility and applicability.

[0036] like Figure 5 As shown, the mixing assembly 3 includes a mixing hopper 31, a mixing unit 32, and a weighing unit. The mixing hopper 31 is mounted on the support box 11, and the mixing unit 32 is disposed within the cavity of the mixing hopper 31. To uniformly mix the powder and liquid into concrete, the mixing unit 32 includes a mixing drive motor (not shown), a rotating shaft 321, and multiple mixing paddles 322. The rotating shaft 321 is vertically disposed inside the cavity of the mixing hopper 31, and its bottom end penetrates through the bottom of the mixing hopper 31 and connects to the drive end of the mixing drive motor, which is located within the cavity of the support box 11. The multiple mixing paddles 322 are spaced apart on the rotating shaft 321. To prevent liquid or concrete from flowing out of the mixing hopper 31, a sealing ring is provided at the connection between the rotating shaft 321 and the bottom of the mixing hopper 31. The mixing drive motor drives the rotating shaft 321 to rotate, which in turn drives the mixing paddles 322 to rotate, thereby mixing the powder and liquid in the mixing hopper 31 to prepare concrete. In this embodiment, there are two stirring paddles 322.

[0037] In this embodiment, the preferred weighing unit is a weight sensor, which is embedded in the bottom of the mixing hopper 31. It is used to weigh the incoming powder and can also weigh the liquid supplied by the water supply assembly 2. Therefore, the weight of each raw material can be weighed directly in the mixing hopper 31, eliminating the need for manual weighing, saving labor costs, and improving production efficiency.

[0038] To prevent external dust, debris, and contaminants from entering the mixing silo 31 and to ensure the purity of the concrete, such as... Figure 4 and Figure 5 As shown, the top of the mixing hopper 31 is open, and a hopper cover 311 is provided on the top of the mixing hopper 31. One end of the hopper cover 311 is hinged to the top of the mixing hopper 31 to cover the opening. At the same time, the closed opening of the mixing hopper 31 can prevent the powder from being lost due to wind or other external forces, thereby reducing waste.

[0039] To allow operators to observe the mixing state of the concrete in mixing hopper 31 and adjust the powder-to-water ratio in a timely manner, such as... Figure 2 As shown, the side wall of the mixing hopper 31 is provided with a viewing window 312.

[0040] like Figure 3 As shown, the water supply assembly 2 includes an inlet pipe 21, a flow valve 22, a flow meter, and a water storage tank 23. Both the flow valve 22 and the flow meter are mounted on the inlet pipe 21. The flow valve 22 is used to adjust the amount of fluid passing through the inlet pipe 21. By changing the opening degree of the flow valve 22, the flow rate and total volume of the liquid can be precisely controlled. The flow meter is used to measure the amount of water entering the inlet pipe 21. The water storage tank 23 is located inside the cavity of the support box 11. The inlet end of the inlet pipe 21 is connected to the water storage tank 23, and the outlet end of the inlet pipe 21 is connected to the cavity of the mixing hopper 31. The water supply assembly 2 adds the corresponding amount of liquid to the mixing hopper 31 according to the weight of the powder measured by the weight sensor, thereby improving the quality of the concrete and ultimately enhancing the performance of the final product.

[0041] Control unit 4 is electrically connected to the weight sensor, the stirring drive motor, and the flow valve 22. Control unit 4 receives the powder weight signal from the weight sensor and, based on the set powder-to-water ratio, sends a corresponding water supply signal to the water supply assembly 2. By adjusting the opening of the flow valve 22, the water inlet pipe 21 delivers the corresponding liquid to the mixing hopper 31. For example... Figure 2 As shown, the control unit 4 includes an electrically connected control cabinet 41 and a control panel 42. The control cabinet 41 is disposed inside the cavity of the support box 11, and the control panel 42 is disposed on the support box 11. The control unit 4 is existing technology, and its specific principle will not be described in detail.

[0042] It should be noted that the stirring device in this embodiment is a physical structure. This embodiment does not involve improvements to computer programs; its main contribution to the prior art lies in the connection or structural relationships between the various components or hardware structures within the stirring device.

[0043] like Figure 2As shown, in order to pump the mixed concrete to the subsequent processing device, the discharge assembly 5 includes a first pump pipe 51, an air compressor 52, and a second pump pipe 53. An installation hole is formed in the side wall of the mixing silo 31. The first pump pipe 51 passes through the installation hole and is fixedly connected to the mixing silo 31. The inlet end of the first pump pipe 51 extends into the cavity of the mixing silo 31, the outlet end of the first pump pipe 51 communicates with the suction end of the air compressor 52, the discharge end of the air compressor 52 communicates with the inlet end of the second pump pipe 53, and the outlet end of the second pump pipe 53 communicates with the subsequent processing device. The side end of the air compressor 52 is fixedly connected to the side wall of the mixing silo 31 via a support rod (not shown) to support the air compressor.

[0044] To prevent powder from spilling and to ensure a clean powder mixing environment, such as Figure 1 As shown, the mixing device also includes a dust cover 6, which has an arc-shaped structure and is set vertically. The bottom end of the dust cover 6 is connected to the top end of the mixing hopper 31, and the opening end of the dust cover 6 faces away from the discharge assembly 5. This ensures a safe production environment while reducing harm to the operator, thereby improving the dust control effect of the mixing device and increasing the powder mixing efficiency.

[0045] To facilitate the addition of powder to the mixing hopper 31 by the operator, the support assembly 1 also includes a ladder 13. One end of the ladder 13 is rotatably connected to the side wall of the support box 11, and when the ladder 13 is unfolded, the other end of the ladder 13 can abut against the ground. Because the ladder 13 is foldable, the mixing device occupies a small area.

[0046] To facilitate the transport of the mixing device, the support assembly 1 also includes four lifting lugs 14, which are respectively connected to the four corners of the top of the support box 11. The lifting lugs 14 provide clear and safe connection points, ensuring the safety and stability of the mixing device during lifting and transportation.

[0047] To enable the stirring device to operate independently in any location, such as Figure 1 As shown, the stirring device also includes a portable power supply 7, which is located inside the cavity of the support box 11. The portable power supply 7 is connected to the weight sensor, the stirring drive motor, the air compressor 52, and the electrical control cabinet 41 to provide power. In the event of a power outage or other emergency, the stirring device can be used normally without the need to find a power source.
