Description

Technical Field

[0001] This utility model relates to the technical field of dust suppression devices, specifically a dust suppression device for concrete processing. Background Technology

[0002] Concrete processing refers to the process of mixing raw materials such as cement, sand, water, and admixtures according to a certain ratio to form a concrete mixture. After processing, the concrete is packaged into bags as needed. By packing the concrete into bags, small-batch, decentralized transportation and storage can be achieved, meeting the needs of small projects, repair work, or home renovation, while avoiding the scattering and waste during the bulk transportation of concrete.

[0003] In existing concrete packaging, concrete is usually conveyed directly to the packaging bag through the discharge pipe at the bottom of the storage hopper. Since concrete contains cement, sand and gravel and other dust-generating components, dust is easily generated during filling, which can pollute the air and endanger the respiratory health of operators. Therefore, a dust suppression device for concrete processing is provided to improve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a dust suppression device for concrete processing. By setting up a dust collection component, it solves the problem that existing concrete packaging often involves directly conveying concrete to the packaging bag through the discharge pipe at the bottom of the storage bucket. Since concrete contains cement, sand and gravel and other easily dusty components, dust is easily generated during filling, which can easily pollute the air and endanger the respiratory health of operators.

[0005] This utility model is achieved through the following technical solution: This utility model is a dust suppression device for concrete processing, including a storage bin, a discharge pipe, and a dust collection component. A support frame is installed on the storage bin, and the dust collection component is set on the support frame. The dust collection component includes a circular frame, a dust collection box, and a fan. The circular frame is installed on the discharge pipe, and a dust collection pipe is installed on the circular frame. A dust collection hood is evenly distributed around the dust collection pipe. A first conveying pipe is connected to the dust collection box. The first conveying pipe is connected to the air outlet of the fan. A second conveying pipe is connected to the air inlet of the fan. The end of the second conveying pipe away from the fan is connected to the dust collection pipe.

[0006] Furthermore, a support plate is installed on the support frame, the dust collection box is installed on the support plate, and the fan is installed on the dust collection box.

[0007] Furthermore, a door is hinged to the opening of the dust collection box.

[0008] Furthermore, the discharge pipe is connected to the bottom of the storage tank, and a valve is installed on the discharge pipe.

[0009] Furthermore, a lid is installed on the top of the storage hopper, and a feed pipe is connected to the lid.

[0010] This utility model has the following beneficial effects: This invention utilizes a dust-collecting component, employing negative pressure generated by a fan to draw in overflowing dust through a dust-collecting hood. The dust drawn in by the hood passes sequentially through a dust-collecting pipe and a second conveying pipe into the fan. After being pressurized by the fan, it is discharged into a dust collection box through a first conveying pipe. This achieves the effect of adsorbing and collecting dust generated during concrete packaging, reducing the dust concentration in the working environment. It solves the problem that existing concrete packaging methods often involve directly conveying concrete to packaging bags through the discharge pipe at the bottom of the storage hopper. Since concrete contains cement, sand, and other easily dust-generating components, dust easily overflows during filling, polluting the air and endangering the respiratory health of operators.

[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a dust suppression device for concrete processing, including a storage bin 1, a discharge pipe 2 and a dust collection component 4. A support frame 3 is installed on the outer wall of the storage bin 1 by welding. The storage bin 1 serves as a storage container for concrete, providing a stable storage space for the concrete.

[0018] The dust collection component 4 is mounted on the support frame 3. The dust collection component 4 includes a circular frame 401, a dust collection box 404, and a fan 406. The circular frame 401 is bolted to the discharge pipe 2. A dust collection pipe 402 is installed on the outer wall of the circular frame 401 by a snap fastener. A circle of dust collection hoods 403 is evenly distributed on the dust collection pipe 402 by a threaded connection. The dust collection hoods 403 are directly aimed at the dust overflow area around the discharge port of the discharge pipe 2, capturing dust at close range. The evenly distributed circle covers a 360° range, eliminating dust collection dead corners and ensuring that dust overflowing from all directions around the bag can be effectively sucked up during packaging.

[0019] A first conveying pipe 405 is connected to the dust collection box 404. The first conveying pipe 405 is connected to the air outlet flange of the fan 406. A second conveying pipe 407 is connected to the air inlet flange of the fan 406. The end of the second conveying pipe 407 away from the fan 406 is connected to the suction pipe 402 by a threaded connection. The fan 406 serves as the power source of the dust collection system. It generates negative pressure through the air inlet to draw the dust captured by the dust collection hood 403 into the suction pipe 402 and the second conveying pipe 407. The dust enters the dust collection box 404 through the air outlet of the fan 406 and the first conveying pipe 405, thus completing the dust collection and reducing the dust concentration in the working environment.

[0020] A support plate 5 is installed on the support frame 3 by welding. The bottom of the dust collection box 404 is bolted to the support plate 5, and the bottom of the fan 406 is bolted to the dust collection box 404.

[0021] The dust collection box 404 has a door 408 hinged to its opening. The dust collection box 404 serves as a centralized storage container for dust, preventing secondary diffusion of dust after vacuuming and facilitating subsequent unified cleaning or recycling. The door 408 is easy to open and clean the dust collected inside the dust collection box 404. It can be equipped with a sealing strip to prevent dust from overflowing from the gaps in the door 408 when not being cleaned.

[0022] The discharge pipe 2 is connected to the bottom of the storage bucket 1 by welding. A valve 201 is installed on the discharge pipe 2. The discharge pipe 2 realizes the directional conveying of concrete from the storage bucket 1 to the packaging bag, avoiding the concrete from scattering randomly. The valve 201 precisely controls the discharge switch and flow rate of concrete. When packaging, the valve 201 is opened to release concrete, and the valve 201 is closed when stopping, to avoid the continuous flow of concrete leading to waste or accumulation.

[0023] The top of the storage hopper 1 is bolted with a hopper cover 6, and a feed pipe 601 is welded to the hopper cover 6. The hopper cover 6 is used to seal the opening of the storage hopper 1, and the feed pipe 601 is used to guide concrete into the storage hopper 1 in a directional manner.

[0024] During operation, the packaging bag is first placed over the outlet of the discharge pipe 2, ensuring that the bag opening is aligned with the discharge port, ready to receive concrete. Then, the blower 406 is turned on. The air inlet of the blower 406 generates negative pressure in the dust suction pipe 402 through the second conveying pipe 407, driving a circle of dust suction hoods 403 to form a suction airflow. Then, the valve 201 on the discharge pipe 2 is opened, and the concrete in the storage bucket 1 flows into the packaging bag through the discharge pipe 2. At this time, the dust overflowing when the concrete is filling the bag is sucked in by the surrounding dust suction hoods 403 in real time. The dust sucked in by the dust suction hoods 403 enters the blower 406 through the dust suction pipe 402 and the second conveying pipe 407 in sequence. After being pressurized by the blower 406, it is discharged into the dust collection box 404 through the first conveying pipe 405. After packaging is completed, the valve 201 is closed to stop the discharge, and then the blower 406 is turned off.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
