Technical Field
[0001] This utility model relates to the field of asphalt concrete production technology, specifically to an environmentally friendly powder dust collection device for asphalt concrete production. Background Technology
[0002] Asphalt concrete is a mixture that is usually made by mixing mineral aggregates, crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., with a certain proportion of road asphalt materials under strict control conditions.
[0003] The production of asphalt concrete often requires mixing various raw materials in a mixing plant. During the feeding process, some powder will be scattered at the feed inlet, which can pollute the surrounding environment and affect the health of nearby workers. Currently, the common method is to install one or more vacuum cleaners on top of or near the mixing plant to absorb the scattered powder. However, this requires regular manual cleaning of the powder inside the vacuum cleaners, increasing the workload of the workers. Utility Model Content

[0005] To address the shortcomings of existing environmentally friendly dust collection devices for asphalt concrete production that lack automatic material discharge, this utility model provides the following technical solution: An environmentally friendly dust collection device for asphalt concrete production includes a cover body. One side of the cover body has an elongated opening. A circular partition is fixedly connected to the inner wall of the cover body. Two extended baffles are welded to the bottom end of the circular partition. A dust collection mechanism is installed on the top surface of the circular partition. A dust discharge cylinder is fixedly connected to the bottom end of the cover body. A cover plate is bolted to the top surface of the cover body. An opening and closing mechanism is installed in the center of the top surface of the cover plate. An exhaust port is opened on the top surface of the cover plate. A filter cloth fixedly connected to the inner wall of the exhaust port is embedded within the exhaust port. Multiple suction holes are opened on the bottom surface of the circular partition.
[0006] As a preferred embodiment of this utility model, the dust collection mechanism includes a box body fixedly connected to the top surface of the circular partition. Two electric impellers are installed on the lower inner wall of the box body. An air guide is provided inside the box body and fixedly connected to its inner wall. A circular opening is provided at the bottom end of the box body, and the circular opening is located directly above the dust exhaust cylinder. A vertical partition is provided inside the box body and fixedly connected to its inner wall. The vertical partition passes through the circular opening and extends into the dust exhaust cylinder.
[0007] As a preferred embodiment of this utility model, the box body has an arc-shaped structure, with openings at both the front and rear ends, and an opening on the top surface.
[0008] As a preferred embodiment of this utility model, the opening and closing mechanism includes an electric push rod fixedly installed above the cover plate, and a sealing block is fixedly connected to the bottom end of the electric push rod, with the top surface of the sealing block abutting the bottom surface of the dust discharge cylinder.
[0009] As a preferred embodiment of this utility model, the sealing block has a conical structure, and the bottom surface of the vertical spacer is at a higher level than the top surface of the sealing block.
[0010] As a preferred embodiment of this utility model, the bottom surface of the cover is welded with a plurality of mounting seats, which are distributed in a circular pattern.
[0011] Compared with the prior art, this utility model provides an environmentally friendly dust collection device for asphalt concrete production, which has the following beneficial effects:
[0012] 1. This environmentally friendly dust collection device for asphalt concrete production can be externally connected to the top of asphalt concrete mixing equipment without requiring extensive modifications to the existing equipment (only a few installation holes are needed). During use, the electric impeller in the dust collection mechanism can be activated, and the powder generated during feeding can be automatically absorbed into the dust discharge cylinder. After feeding is completed, the electric push rod can be activated to move the sealing block downward, allowing the collected powder to automatically fall into the mixing equipment. There is no need to manually remove the material or manually pour it back into the mixing equipment, which can effectively reduce the workload of the workers and also effectively prevent the indiscriminate spread of powder, thus playing an environmental protection role.
[0013] 2. This environmentally friendly dust collection device for asphalt concrete production has an overall shell structure, which makes it difficult for powder to spread and facilitates absorption. It is also equipped with an extended baffle and a larger suction hole, which prevents dust from flowing out of the long opening and ensures full absorption of powder. Attached Figure Description

Detailed Implementation
[0020] 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.
[0021] Please see Figures 1-4 This utility model discloses an environmentally friendly dust collection device for asphalt concrete production, including a cover 10. A long opening 20 is provided on one side of the cover 10. A circular partition 30 is fixedly connected to the inner wall of the cover 10. Two extended baffles 100 are welded to the bottom end of the circular partition 30. A dust suction mechanism 40 is installed on the top surface of the circular partition 30. A dust discharge cylinder 50 is fixedly connected to the bottom end of the cover 10. A cover plate 60 is bolted to the top surface of the cover 10. An opening and closing mechanism 70 is installed in the middle of the top surface of the cover plate 60. An exhaust port 80 is provided on the top surface of the cover plate 60. A dust filter cloth fixedly connected to the inner wall of the exhaust port 80 is embedded in the exhaust port 80. Multiple suction holes 90 are provided on the bottom surface of the circular partition 30.
[0022] The hood 10 reduces the diffusion of powder, and the long opening 20 allows the discharge end of the elevator to extend into the hood 10, so that the asphalt concrete raw materials can be poured into the mixing equipment. The dust discharge cylinder 50 can store powder and is inserted into the feed inlet above the mixing equipment, so that the powder can be discharged into the mixing equipment.
[0023] Specifically, the vacuuming mechanism 40 includes a box 41 fixedly connected to the top surface of the circular partition 30. Two electric impellers 42 are installed on the lower inner wall of the box 41. An air guide 43 fixedly connected to the inner wall of the box 41 is provided inside the box 41. A circular opening 44 is opened at the bottom of the box 41. The circular opening 44 is located directly above the dust exhaust cylinder 50. A vertical partition 45 fixedly connected to the inner wall of the box 41 is provided inside the box 41. The vertical partition 45 passes through the circular opening 44 and extends into the dust exhaust cylinder 50. The box 41 has an arc-shaped structure. Both the front and rear ends of the box 41 are open. The top surface of the box 41 is also open.
[0024] In this embodiment, the electric impeller 42 consists of a motor and multiple impellers, which has a good dust collection effect. The powder will not drift to the outside of the cover 10, and the surrounding environment is good, which can play an environmental protection role in the vicinity.
[0025] Specifically, the opening and closing mechanism 70 includes an electric push rod 71 fixedly installed above the cover plate 60. A sealing block 72 is fixedly connected to the bottom end of the electric push rod 71. The top surface of the sealing block 72 is attached to the bottom surface of the dust discharge cylinder 50. The sealing block 72 has a conical structure, and the bottom surface of the vertical partition 45 is higher than the top surface of the sealing block 72.
[0026] In this embodiment, during the feeding process, the electric push rod 71 is in a retracted state, and the sealing block 72 is tightly attached to the bottom surface of the dust discharge cylinder 50. At this time, the bottom end of the dust discharge cylinder 50 is in a sealed state, and the absorbed gas and powder will not be discharged from the bottom of the dust discharge cylinder 50 together, thus preventing the powder from flying around. After the feeding is completed, the electric impeller 42 is turned off, and the electric push rod 71 can be started to drive the sealing block 72 to move down, and the powder will automatically fall into the asphalt concrete mixing equipment.
[0027] Specifically, the bottom surface of the cover 10 is welded with multiple mounting seats 110, which are distributed in a circular pattern.
[0028] In this implementation plan, multiple mounting holes are simply opened on the top surface of the asphalt concrete mixing equipment to achieve the fixed installation of the entire powder dust collection device.
[0029] The working principle and usage process of this utility model are as follows: When feeding is required, the electric impeller 42 is started. At this time, the cavity formed between the circular partition 30 and the cover 10 can form a negative pressure. When feeding, the suction hole 90 can generate suction, thereby absorbing the powder inside the cover 10. Under the filtration of the dust filter cloth, the collected powder stays in the dust discharge cylinder 50, while the clean gas is discharged from the exhaust port 80. After feeding is completed, the electric impeller 42 is turned off, and the electric push rod 71 is started to drive the sealing block 72 to move down. The sealing block 72 separates from the dust discharge cylinder 50, and the powder automatically falls into the asphalt concrete mixing equipment.
