Description

Technical Field

[0001] The utility model relates to the technical field of road maintenance, in particular to a dust and soot removal device for road maintenance vehicles. Background Technique

[0002] With the acceleration of the urbanization process, road maintenance operations (such as asphalt paving, milling, and caulking) are becoming increasingly frequent, and a large amount of dust and harmful gases will be generated during the construction process. These pollutants not only affect the health of construction workers but also have an adverse impact on the surrounding environment and the lives of residents. Therefore, efficient and environmentally friendly dust control technology has become an important supporting requirement for road maintenance vehicles.

[0003] After retrieval, a Chinese utility model patent with the authorization announcement number of CN221673725U, a dust and soot removal device for road maintenance vehicles, relates to the technical field of road maintenance, including a trolley, a lifting plate, and a sealing ring. The bottom end of the mounting plate is respectively installed with a HEPA filter and an activated carbon filter. On both sides of the inner walls at both ends of the mounting plate, a return spring is installed, and one side of each return spring is connected to a clamping rod. By squeezing the two squeezing plates inward, the squeezing plates drive the clamping rods to move away from the clamping grooves simultaneously, and the return springs are deformed by extrusion. Then, the mounting plate in the mounting hole is taken out, which is convenient for disassembling and replacing the HEPA filter and the activated carbon filter, and solves the problem of inconvenient disassembly and replacement.

[0004] However, the above patent filters dust and soot through a HEPA filter and an activated carbon filter. Its filtering path is short, the filtering effect is limited, and the filter screen needs to be frequently disassembled and assembled to meet the filtering requirements. In view of this, the present application further proposes a dust and soot removal device for road maintenance vehicles based on the above technical problems. Content of the Utility Model

[0013] Further, the top of the dust collection bin is set as an inclined surface facing the box door.

[0014] Further, the surface of the cloth bag is coated with a polytetrafluoroethylene coating.

[0015] The beneficial effects of the utility model are as follows:

[0016] 1. The utility model is provided with a cloth bag, a dust suction hopper, a negative pressure fan, and a jet nozzle. During road maintenance, the negative pressure fan operates, generating a negative pressure suction force at the dust suction hopper. The soot enters the interior of the lower shell from the dust suction hopper, and the soot airflow then passes through multiple cloth bags for filtration. Smaller particulate matters are intercepted therein, and the purified gas is discharged from the exhaust pipe. When there is too much dust on the cloth bag, high-pressure gas can be sprayed from the jet nozzle towards the cloth bag through the gas tank, causing the cloth bag to expand, and thus the small particulate matters therein are shaken off into the dust collection bin.

When the negative pressure airflow sucks the cloth bag, the cloth bag will not be distorted, thus avoiding affecting the original filtration effect.

[0018] 3. The utility model is provided with a partition board and a deflector. On the one hand, the partition board is used for the installation of the cloth bag, and on the other hand, it prevents the unfiltered soot from overflowing. Under the blockage of the deflector, the soot airflow, on the one hand, causes larger particulate matters to settle in the dust collection bin, and on the other hand, increases the flow path of the soot airflow.

[0019] 4. The utility model is provided with a spray assembly. Since dust will be generated during road maintenance, at this time, the water pump is started to increase the pressure of the water flow from the water spray pipe to the water spray head, thereby generating water mist, which can effectively adsorb and settle the dust particles in the air, thus achieving the purpose of reducing dust and improving the construction environment.

[0020] 5. The utility model is provided with a dust collection bin, a cylinder, and a box door. After the soot removal work is completed, the cylinder is started, and the cylinder drives the box door to rotate, and the dust is discharged from the dust collection bin.

[0031] During road maintenance, the negative pressure fan 11 operates, generating negative pressure suction at the dust suction hopper 7. The dust and smoke enter the interior of the lower shell 2 from the dust suction hopper 7. The dust and smoke airflow passes through multiple filter bags 6 for filtration. Smaller particulate matters are intercepted therein, and the purified gas is discharged from the exhaust pipe 13. When there is too much dust on the filter bags 6, high-pressure gas can be sprayed from the gas injection nozzle 10 towards the filter bags 6 through the gas tank 8.

At this time, the bottom cover 21 is located at the lowest end of the filter bag 6, the support rods 19 are attached to the inner side of the filter bag 6, and the top cover 18 is located above the partition plate 4. When negative pressure airflow sucks the filter bag 6, the filter bag 6 will not be distorted, thus avoiding affecting the original filtration effect.

[0037] Refer to Figure 3 , specifically: the top of the dust collection bin 14 is provided with an inclined surface facing the box door 28, which is convenient for the discharge of dust.

[0038] Specifically: the surface of the cloth bag 6 is coated with a polytetrafluoroethylene coating, which effectively resists the adhesion of oily particles generated by asphalt paving on the cloth bag 6.

[0039] Working principle: During road maintenance, the negative pressure fan 11 works, and a negative pressure suction force is generated at the dust suction hopper 7. The dust and smoke enter the interior of the lower shell 2 from the dust suction hopper 7. Under the obstruction of the guide plate 16, on the one hand, the larger particulate matter settles in the dust collection bin 14, and on the other hand, the flow path of the dust and smoke airflow is increased. The dust and smoke airflow passes through multiple cloth bags 6 for filtration, and the smaller particulate matter is intercepted therein. The purified gas is discharged from the exhaust pipe 13. When there is too much dust on the cloth bag 6, the high-pressure gas can be sprayed from the jet nozzle 10 to the cloth bag 6 through the gas tank 8, and the cloth bag 6 expands, so that the small particulate matter therein is shaken off into the dust collection bin 14;

[0040] After the dust removal work is completed, the cylinder 31 is started, and the cylinder 31 drives the box door 28 to rotate, and the dust is discharged from the dust collection bin 14;

[0041] Since dust will be generated during road maintenance, at this time, the water pump 23 is started, and the water flow is pressurized from the water spray pipe 25 to the water spray head 26, thereby generating water mist, which can effectively adsorb and settle the dust particles in the air, so as to achieve the purpose of reducing dust and improving the construction environment;

[0042] When the cloth bag 6 is installed, it is clamped on the installation hole 5 through the expansion ring 22, and then the support assembly is placed inside the cloth bag 6. At this time, the bottom cover 21 is located at the lowest end of the cloth bag 6, the support rod 19 is attached to the inner side of the cloth bag 6, and the top cover 18 is located above the partition plate 4. When the negative pressure airflow sucks the cloth bag 6, the cloth bag 6 will not be distorted, thus avoiding affecting the original filtration effect. The partition plate 4 is used for the installation of the cloth bag 6 on the one hand and prevents the unfiltered dust and smoke from overflowing on the other hand. By coating the surface of the cloth bag 6 with a polytetrafluoroethylene coating, it effectively resists the adhesion of oily particles generated by asphalt paving on the cloth bag 6.
