Description

Dust removal device for road construction

technical field

The utility model relates to the field of road construction, in particular to a dust removal device for road construction.

Background technique

In the process of road construction, it is often necessary to excavate the soil, so that the dust generated by the excavation will float in the air, affecting the entire construction environment, reducing the air quality around the construction, and causing greater harm to human health. Especially when the vehicle passes by, the vehicle will drive a part of the dust to float in the air.

In order to solve the above problems, the dust on the ground is now bonded to the ground by means of watering vehicles to prevent the dust from floating upwards into the air, thereby improving the air quality. However, because the sprinkler needs to spray water on the ground, the ground is in a relatively wet state for a long time, and the soil on the ground is easy for workers to slip, which is not convenient for workers to walk. Moreover, the sprinkler sprays water on the ground, and the water that is sprinkled on the ground is evaporated and cannot be reused, which easily causes waste of water resources.

Utility model content

The purpose of the utility model is to provide a dust removal device for road construction, so as to reduce the waste of water and realize the repeated recycling of water during the dust removal process.

In order to achieve the above purpose, the technical solution of the present utility model is: a dust removal device for road construction, including a box body, a cavity is provided in the box body, an inlet communicating with the cavity is provided on the box body, and the cavity is rotatably connected There are fan blades and a driving mechanism for driving the fan blades to rotate. There is a nozzle on the top of the cavity, a water collection tank under the nozzle, a filter plate in the water collection tank, a circulation pump in the cavity, and the circulation pump and the collection tank. A water outlet pipe is connected between the bottoms of the water tank, and a water inlet pipe is connected between the circulation pump and the spray nozzle.

The working principle of this scheme is: the inlet is used to make the dust from the outside enter the box body. The driving mechanism is used to drive the fan blades to rotate, and the rotation of the fan blades generates airflow, thereby sucking dust from the outside into the cavity. The nozzle is used for spraying water, and the sprayed water makes the dust floating in the cavity wet, and the gravity of the dust becomes larger, thereby accelerating the settlement of the dust. The settled dust falls into the sump, and the filter plate is used for filtering, so that the water droplets fall to the bottom of the filter plate to be collected, and the dust is isolated on the filter plate. The circulation pump is used to re-pump the water collected in the sump into the nozzle, thereby realizing the recycling of water and reducing the waste of water.

When adopting the above-mentioned technical scheme, the settlement of dust in the box is realized without spraying water on the ground, and the ground remains relatively dry, which is convenient for workers and vehicles to walk. The water in this scheme is collected again in the sump, and the water can be recycled many times, thereby saving water resources.

Further, the cavity is provided with a rotating roller located between the sump and the nozzle, the rotating roller rotates in the cavity, the rotating roller is provided with an air suction pump, the surface of the rotating roller is provided with an air suction hole, and the air suction hole is provided with a suction hole. There is a filter screen, and a mud scraper is arranged on the collection tank, and the mud scraper is offset against the surface of the rotating roller. The suction pump is used for suction. When the suction pump sucks air, the suction pump generates airflow through the suction hole, so that the dust in the cavity is approached to the direction of the rotating roller, so that the dust moves directional and adheres to the rotating roller. The speed of dust settling is improved, and the dust is prevented from floating irregularly in the cavity. The filter screen is used to filter the dust to prevent the dust from entering the rotating roller through the suction hole. During the rotation of the rotating roller, since the scraper is in contact with the surface of the rotating roller, the dust adhering to the rotating roller can be scraped off by the scraper, thereby ensuring the adhesion of the rotating plate. The scraped dust falls on the filter plate in the sump under the action of its own gravity.

Further, a cylinder is provided in the cavity, and the cylinder rod of the cylinder is fixedly connected with a mud pushing plate that is slidably connected on the filter plate. The soil on the top enters the mud hole in the mud sump. When there is too much dust on the filter plate, start the cylinder, and the cylinder pushes the mud pushing plate to slide, and the mud pushing plate slides on the filter plate, thereby pushing the dust adhering to the filter plate into the mud collecting tank through the mud holes, and the mud collecting The grooves collect the dust. Thereby, excessive dust adhering to the filter plate can be prevented, and the filtering capacity of the filter plate can be ensured.

Further, a partition is provided in the cavity, the surface of the rotating roller passes through the partition, and the water collection tank and the mud collection tank are both located under the partition. Partition plate can play the effect of separation, prevents dust from floating to other positions in the cavity, and ensures that dust can fall on the rotating roller.

Further, the driving mechanism includes a motor and a rotating shaft connected in the cavity, the fan blade is located on the rotating shaft, and a belt is connected between the motor and the rotating shaft; the first gear is coaxially connected to the rotating roller, and the second gear is coaxially connected to the rotating shaft. gears, the first gear meshes with the second gear. The motor drives the rotating shaft to rotate through the belt, the rotating shaft drives the fan blades to rotate, and the rotating shaft drives the rotating roller to rotate through the meshing of the first gear and the second gear. Therefore, the same power source is used for the rotation of the fan blade and the rotation of the rotating roller, which is beneficial to energy saving.

Further, the second gear is provided with a through hole. The through hole on the second gear can make the dust coming in from the inlet flow to the bottom of the shower head through the second gear, preventing the second gear from blocking the dust from moving to the bottom of the shower head.
