Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and more specifically to a dust removal device for an asphalt concrete mixing plant. Background Technology

[0002] Asphalt concrete mixing plants are complete sets of equipment used for the mass production of asphalt concrete, playing an indispensable role in the construction of highways, roads, municipal roads, airports, and ports. During the production process, the heating and mixing of raw materials, especially dry materials, generates a large amount of dust. This dust disperses into the air, causing significant environmental pollution. Therefore, dust collection and treatment devices are necessary to collect and treat the dust.

[0003] As shown in the prior art published in CN220589293U, although this prior art can extract air from the asphalt concrete mixing plant by installing a fan, and the dust-laden air is filtered through a filter screen inside the dust collector to achieve dust removal, the dust removal structure of this prior art is relatively complex, consisting of gear sets and reciprocating screws, which increases the overall cost. Utility Model Content

[0004] To overcome the aforementioned deficiencies in the prior art, this utility model provides a dust removal device for an asphalt concrete mixing plant. A fan drives a linkage shaft, which in turn drives a brush plate via a linkage ring and a linkage plate. The brush plate simultaneously cleans the air duct and filter screen, preventing dust from clogging the filter screen and simultaneously cleaning the air duct. This improves the dust removal efficiency. Furthermore, the overall structure is simple, effectively reducing construction and maintenance costs, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for an asphalt concrete mixing plant, comprising an air duct, wherein the air duct is provided with a dust collection component for dust suction, and the air duct is cleaned of dust by an auxiliary component; The auxiliary component includes a linkage shaft installed inside the air duct. The top and bottom of the linkage shaft are provided with L-shaped brush plates.

The positioning component includes a linkage ring sleeved on the outside of the linkage shaft, and two linkage plates for connecting the brush plate are installed at the top and bottom of the linkage ring.

[0006] In a preferred embodiment, the collecting component includes a fan and a filter screen installed inside the duct. The fan is located in front of the filter screen, and the filter screen is sleeved outside the linkage shaft. The front end of the linkage shaft is fixed together with the output shaft of the fan. The front side of the brush plate contacts the rear side of the filter screen. The fan draws the smoke and dust into the duct, and then the filter screen filters the smoke and dust.

[0007] In a preferred embodiment, a positioning ring is sleeved on the rear end of the linkage shaft and movably connected by a bearing. Multiple positioning brackets for connecting air ducts are installed on the outside of the positioning ring. The linkage shaft is supported from multiple directions by the positioning ring and multiple positioning brackets, thereby ensuring the stability of the linkage shaft and preventing the linkage shaft from tilting.

[0008] In a preferred embodiment, the bottom of the air duct is provided with an assembly hole, and a material pipe is installed inside the assembly hole; A material cylinder is provided at the bottom of the air duct on one side corresponding to the material pipe. The bottom end of the material pipe is fixedly connected to the material cylinder. A slag collection cylinder is provided inside the material cylinder.

[0009] In a preferred embodiment, limiting plates are installed on both sides of the slag collecting cylinder, and a limiting hole is opened on the side of the cylinder corresponding to the limiting plate. The limiting plate is located inside the limiting hole. By engaging the limiting plate and the limiting hole, the slag collecting cylinder can be limited and fixed, ensuring the stability of the slag collecting cylinder and preventing the slag collecting cylinder from tilting or shaking.

[0010] In a preferred embodiment, a sealing cylinder is externally threaded to the front end of the material cylinder. The sealing cylinder is located on the front side of the slag collection cylinder. The sealing cylinder is threaded to the material cylinder, so that after the sealing cylinder is assembled to the outside of the material cylinder, it can limit the slag collection cylinder and prevent the slag collection cylinder from separating from the material cylinder. After the sealing cylinder is removed, the unrestricted slag collection cylinder can be easily removed.

[0011] The technical effects and advantages of this utility model are as follows: The fan drives the linkage shaft to rotate, which in turn drives the brush plate to rotate via the linkage ring and linkage plate.

Detailed Implementation

[0014] 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.

[0015] Refer to the instruction manual appendix Figure 1-5 This utility model provides a dust removal device for an asphalt concrete mixing plant, including a duct 1. The duct 1 is equipped with a dust collection component inside, and the duct 1 is cleaned of dust by an auxiliary component. The auxiliary component includes a linkage shaft 2 installed inside the duct 1. The top and bottom of the linkage shaft 2 are equipped with L-shaped brush plates 3. The side of the brush plate 3 away from the linkage shaft 2 contacts the inner wall of the duct 1, and the outside of the linkage shaft 2 is equipped with a positioning component for supporting the brush plate 3. The positioning component includes a linkage ring 4 sleeved on the outside of the linkage shaft 2. The top and bottom of the linkage ring 4 are equipped with two linkage plates 5 for connecting the brush plates 3.

[0016] To avoid environmental pollution and health hazards caused by fumes from mixing asphalt concrete, duct 1 can be installed on the mixing equipment. A collection device can then be used to collect and treat the fumes. This collection device includes a fan 6 and a filter screen 7 installed inside the duct 1. The fan 6 is positioned in front of the filter screen 7, which is fitted over a linkage shaft 2. The front end of the linkage shaft 2 is fixed to the output shaft of the fan 6. The front side of the brush plate 3 contacts the rear side of the filter screen 7. In this way, the fan 6 draws the fumes into the duct 1, where they are then intercepted and collected by the filter screen 7. To ensure the filtration effect of filter 7, it is necessary to clean filter 7 with the help of auxiliary components. Since the linkage shaft 2 on the auxiliary components is connected to the output shaft of the fan 6, the linkage shaft 2 can drive the linkage ring 4 to rotate with the fan 6. The linkage ring 4 then drives the brush plate 3 to rotate through the linkage plate 5. The brush plate 3 simultaneously cleans the inner wall of the air duct 1 and filter 7, thereby preventing smoke and dust from clogging filter 7 and cleaning the inner wall of air duct 1 to prevent smoke and dust accumulation from affecting dust collection efficiency.

[0017] To facilitate the treatment of the swept dust, an assembly hole 10 is provided at the bottom of the air duct 1, and a material pipe 11 is installed inside the assembly hole 10. A material cylinder 12 is provided on the bottom of the air duct 1 corresponding to the material pipe 11, and the bottom end of the material pipe 11 is fixedly connected to the material cylinder 12. A slag collection cylinder 13 is provided inside the material cylinder 12, and a slag collection hole 14 is provided on the top of the slag collection cylinder 13 corresponding to the material pipe 11. In this way, after the brush plate 3 sweeps off the dust, the dust can still be scraped through the material cylinder 12 into the slag collection cylinder 13 inside the material cylinder 12, where the dust is collected and stored, thereby achieving centralized treatment of the dust.

[0018] Meanwhile, to ensure the operational stability of the aforementioned linkage shaft 2, it is necessary to provide limiting support for the linkage shaft 2. Therefore, a positioning ring 8 is fitted onto the outer rear end of the linkage shaft 2 via a bearing, and multiple positioning brackets 9 for connecting the air duct 1 are installed on the outside of the positioning ring 8. In this way, the positioning brackets 9 and the positioning ring 8 can provide multi-directional support and limiting for the linkage shaft 2, ensuring the stability of the linkage shaft 2 and preventing the linkage shaft 2 from tilting or shaking.

[0019] Furthermore, the front end of the material cylinder 12 is externally threaded with a sealing cylinder 17, which is located on the front side of the slag collection cylinder 13. This allows the operator to rotate the sealing cylinder 17 to separate it from the material cylinder 12, facilitating the removal of the unrestricted slag collection cylinder 13 and the processing of the dust inside. Additionally, the slag collection cylinder 13 has limiting plates 15 installed on both sides, and the material cylinder 12 has a limiting hole 16 on the side corresponding to the limiting plate 15, with the limiting plate 15 located inside the limiting hole 16. This allows the operator to limit the slag collection cylinder 13 by engaging the limiting plate 15 with the limiting hole 16 when placing it into the material cylinder 12, ensuring the stability of the slag collection cylinder 13, preventing it from tilting or wobbling, and ensuring that the slag collection hole 14 aligns with the material pipe 11, guaranteeing that the dust falls accurately into the slag collection cylinder 13.

[0020] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
