Description

Technical Field

[0001] This utility model relates to the technical field of dust treatment devices, and in particular to a dust treatment device for concrete manufacturing. Background Technology

[0002] Concrete mixing tanks generate a large amount of dust during operation, which not only pollutes the surrounding environment but may also negatively impact worker health. Therefore, the use of dust control equipment is crucial. Dust control systems typically consist of a dust collector, a fan, a piping system, and a control system. The dust collector is the core equipment, responsible for collecting and filtering dust from the air. Common types include baghouse dust collectors, cyclone dust collectors, and wet scrubbers. The fan generates negative pressure, drawing air out of the mixing tank and sending it to the dust collector for filtration. The piping system connects all components, ensuring that dust can be smoothly extracted, while the control system enables automated monitoring and adjustment, improving the system's operating efficiency. Specifically, after the fan starts, it generates negative pressure, drawing out air containing dust. When passing through the dust collector, the dust particles are effectively separated due to inertia and filtration. The clean air is then discharged into the atmosphere or recycled after further treatment. The dust accumulated at the bottom of the dust collector can be cleaned regularly to avoid secondary pollution. However, during the use of current dust treatment devices, some dust will overflow. Even with the addition of spray dust suppression equipment, dust will still overflow due to intermittent spraying. This is because the design of spray dust suppression equipment usually considers the distribution and spacing of the spray heads. If the spacing between the spray heads is set too large, it will result in insufficient spray coverage, forming "blind spots." In these blind spots, dust cannot be effectively captured and controlled, easily leading to dust overflow and making it impossible to effectively control the dust. Utility Model Content

[0003] The purpose of this utility model is to provide a concrete manufacturing dust treatment device to solve the problems mentioned in the background art, such as the limited functionality and poor dust reduction effect of existing concrete manufacturing dust treatment devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a concrete manufacturing dust treatment device, comprising a dust collection main box and a square-mouthed right-angled air inlet pipe, wherein square-mouthed right-angled air inlet pipes are connected to both sides of the dust collection main box;

[0005] The dust collection main box is connected to air collection hoods at both the front and rear ends, and one end of each air collection hood is connected to an air collection pipe. One end of each air collection pipe is connected to a front air box, and the bottom of each front air box is connected to a centrifugal fan. A dust suppression spraying mechanism is installed at the bottom of the dust collection main box.

[0006] Preferably, the side of the air collecting hood closest to the main dust collecting box is connected to a filter screen, and one side of the filter screen is covered with a nylon fiber synthetic resin membrane.

[0007] Preferably, the dust suppression spraying mechanism includes a drive motor, which is mounted on the outside of the square right-angle air inlet pipe via a bracket. The output shaft of the drive motor is connected to a drive wheel, and a rotating component is provided on one side of the drive wheel.

[0008] Preferably, the rotating assembly includes a rotary joint disposed inside the main dust collection box, and the rotary joint is fixedly installed at the center of the bottom of the main dust collection box. A main flow pipe is rotatably connected inside the rotary joint, and an annular hollow water tank is connected to the bottom end of the main flow pipe. Spray pipes are evenly connected to the bottom end of the annular hollow water tank.

[0009] Preferably, the rotary joint has a water inlet pipe connected to its inner top, and one end of the water inlet pipe is connected to an external water supply.

[0010] Preferably, multiple nozzles are evenly arranged at the bottom of the annular hollow water tank, and the multiple nozzles are distributed in a ring shape on the annular hollow water tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the concrete manufacturing dust treatment device can not only efficiently absorb dust, but also simultaneously reduce dust, resulting in high overall dust treatment efficiency;

[0012] The centrifugal fan is driven in conjunction with the air collection duct, air collection hood, dust collection main box and square right-angle air inlet pipe to draw dust from the concrete manufacturing process into the dust collection main box for dust removal. A filter screen is installed in the air collection hood and covered with a nylon fiber synthetic resin membrane to prevent dust from being drawn into the centrifugal fan and help extend the service life of the centrifugal fan.

[0013] The system connects to an external water supply via an inlet pipe, injects water into a ring-shaped hollow water tank through a main pipe, and then sprays it evenly through multiple nozzles to suppress dust generated during the concrete manufacturing process. The ring-shaped hollow water tank rotates synchronously under the rotation of the drive wheel, which in turn causes the multiple nozzles to rotate, thereby expanding the spraying range and more comprehensively capturing and settling dust particles in the air, improving dust suppression efficiency and enhancing the dust suppression effect.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Please see Figures 1-5 The present invention provides the following technical solution:

[0023] Example 1

[0024] To address the problem of low dust handling efficiency in existing technologies, the following technical solution is proposed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 3 A dust treatment device for concrete manufacturing includes a main dust collection box 1 and a square-mouthed right-angled air inlet pipe 2. The main dust collection box 1 is connected to both sides of the square-mouthed right-angled air inlet pipe 2. The main dust collection box 1 is connected to both the front and rear ends of the main dust collection box 1. The air collection hood 6 is connected to one end of the air collection hood 6 and the air collection pipe 4 is connected to one end of the air collection pipe 4 and the front air box 3 is connected to the bottom end of the front air box 3. The side of the air collection hood 6 closest to the main dust collection box 1 is connected to a filter screen 7 and the side of the filter screen 7 is covered with a nylon fiber synthetic resin membrane.

[0025] In this embodiment, the dust collection box 1 and the square right-angle air inlet pipe 2 are installed at the corresponding position in the concrete manufacturing process using a bracket. Then, two centrifugal fans 5 are driven to draw the dust generated during the concrete manufacturing process into the dust collection box 1 through the square right-angle air inlet pipe 2. During this process, the dust is intercepted by the filter screen 7 and the nylon fiber synthetic resin membrane covering the filter screen 7, preventing the dust from entering the centrifugal fan 5 and affecting its service life.

[0026] Example 2

[0027] This embodiment differs from Embodiment 1 in that it utilizes the spray dust suppression mechanism 8 to achieve efficient dust suppression during the concrete manufacturing process. Therefore, the following technical solution is disclosed; please refer to the details. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A dust suppression spraying mechanism 8 is provided at the bottom of the main dust collection box 1. The dust suppression spraying mechanism 8 includes a drive motor 806, which is mounted on the outside of the square right-angle air inlet pipe 2 via a bracket. The output shaft of the drive motor 806 is connected to a drive wheel 807, and a rotating component is provided on one side of the drive wheel 807. The rotating component includes a rotary joint 805 located inside the main dust collection box 1, and the rotary joint 805 is fixedly installed at the center of the bottom of the main dust collection box 1. The rotary joint 805 is rotatably connected to a main pipe 803. The bottom end of the main pipe 803 is connected to an annular hollow water tank 801. Spray pipes 802 are evenly connected to the bottom end of the annular hollow water tank 801. The top end of the rotary joint 805 is connected to a water inlet pipe 804. One end of the water inlet pipe 804 is connected to an external water supply end. Multiple spray pipes 802 are evenly arranged at the bottom end of the annular hollow water tank 801. The multiple spray pipes 802 are distributed in a ring on the annular hollow water tank 801.

[0028] In this embodiment, during the dust extraction process of the centrifugal fan 5, one end of the water inlet pipe 804 is connected to the external water supply end, so that water can be injected into the annular hollow water tank 801 through the main pipe 803, and then sprayed out through the spray pipe 802. Multiple spray pipes 802 are arranged in a ring on the annular hollow water tank 801, thus ensuring the comprehensiveness of dust suppression spraying. Then, the drive motor 806 drives the drive wheel 807 to rotate. During the rotation of the drive wheel 807, it rubs against the annular hollow water tank 801, causing the annular hollow water tank 801 to rotate, thereby further expanding the spraying range, ensuring that the water mist covers the entire working area, reducing the generation of blind spots, and improving the efficiency of dust suppression.
