Description

Technical Field

[0001] The invention relates to the technical field of environmental protection, and in particular to a dust filtering and processing device and a processing method for road construction. Background Art

[0002] A large amount of dust will be generated during road construction, which will not only harm the health of construction workers, but also affect the surrounding environment and air quality. In order to solve this problem, a dust filtration and treatment device is needed to effectively treat the dust generated by construction, thereby protecting the health of construction workers and reducing pollution to the environment.

[0003] A road engineering dust filtering device disclosed in a patent application with reference publication number CN215506199U is a device in which a box is fixedly installed and used by setting a mounting block, and the installation of a threaded bolt and an upper threaded groove raises the height of a push plate and a lifting plate, so that the moving wheels are separated from the ground, thereby reducing the space occupied by the box. When the box is pushed and used, the push plate and the lifting plate are pushed downward for installation, and the moving wheels are moved in contact with the ground. The incoming air is sprayed by the setting of a water pump and a water pipe, so that the dust sinks.

[0004] Comprehensive analysis of the above reference patents shows the following defects: The existing dust filtering and processing devices and processing methods for road construction are mainly composed of a processing barrel, a liquid spraying mechanism and a filter cartridge mechanism. The liquid spraying mechanism is used to spray water into the processing barrel to perform preliminary dust reduction on the dust-containing air drawn into the processing barrel, and then the filter cartridge mechanism is used to filter the gas again. Since the liquid spraying mechanism and the filter cartridge mechanism are in contact with the dust-containing gas for a long time, it is easy to affect the water spraying effect and the normal filtering of the gas. Usually, an additional driving mechanism is separately provided to clean the liquid spraying mechanism and the filter cartridge mechanism. However, this approach increases the complexity and cost of the device and lacks a built-in effective and self-cleaning mechanism. Therefore, it is necessary to provide a dust filtering and processing device and processing method for road construction to solve the above-mentioned technical problems. Summary of the invention

Through each suction pipe, the dusty air around the outside is sucked into the processing barrel. The dusty air flows upward in the processing barrel. Start the external pump body to suck the external water into the spray mechanism. The spray mechanism guides the water into the processing barrel and sprays it downwards onto the surface of the polypropylene filler ball. The dusty air flowing upwards meets the water sprayed downwards on the surface and surrounding area of ​​the polypropylene filler ball, so that the water and the dusty air are fully contacted and mixed. In the process, the dust particles in the air are adsorbed, intercepted and settled by the water, and the dust is preliminarily removed. Step 2: At the same time, the water droplets flowing downward intercept and capture the coarse particles in the gas, and separate the coarse particles in the gas. The gas that has been initially filtered continues to flow upward, passes through the conical filter plate, and then enters the filter cartridge mechanism. Under the action of the filter cartridge mechanism, the dust in the gas is further filtered; Step three, as the gas enters the treatment barrel through the suction pipe, the fast-flowing gas drives the functional frame mechanism to work. During the operation of the functional frame mechanism, the gas is disturbed, so that the gas passes evenly through the load-bearing mesh plate and enters between several polypropylene filler balls. The working functional frame mechanism scrapes the upper surface of the conical filter mesh plate and drives the liquid spray mechanism and the filter cartridge mechanism for self-cleaning at the same time, so that the water is sprayed out normally and the gas flows upward normally through the filter cartridge mechanism. Finally, the filtered gas is discharged through the exhaust pipe. Beneficial Effects

During the working process of the functional frame mechanism, it can not only disturb the gas so that the gas and the sprayed water are fully contacted and mixed, but also clean the upper surface of the conical filter screen plate to avoid the clogging of the conical filter screen plate, and at the same time drive the liquid spraying mechanism and the filter cartridge mechanism to self-clean, avoid dust particles clogging the nozzle and the filter hole, ensure that the water can be sprayed out normally, and ensure that the gas can flow upward normally through the filter cartridge mechanism. A built-in effective and self-cleaning mechanism is designed, and the effective self-cleaning of the liquid spraying mechanism and the filter cartridge mechanism can be achieved without the need to set up an additional driving mechanism separately, saving costs and ensuring the stable operation of the device.

[0017] 2. A dust filtering and processing device and processing method for road construction. Through the mutual cooperation between an air pump, a shaft, a support plate and fan blades, the air containing dust enters the processing barrel through each suction pipe under the suction of the air pump. Under the continuous impact of the airflow, the fan blades in the processing barrel can be driven to rotate rapidly, and then the shaft is driven to rotate, thereby achieving the purpose of driving the trapezoidal protrusion, the brush and the second gear to rotate. There is no need to set up an additional driving mechanism to drive the work, thereby achieving effective use of energy and reducing the complexity and cost of the device.

[0018] 3. A dust filtering and processing device and processing method for road construction.

During the rotation of the two trapezoidal protrusions, they will pass directly above the corresponding semicircular blocks respectively, and push the two semicircular blocks downward at the same time. The spring is compressed and the anti-blocking ring assembly is pushed downward accordingly. During the process, the soft brush can be used to clean the nozzle in time to avoid the nozzle being blocked by dust particles, thereby ensuring the normal use of the nozzle.

[0019] 4. A dust filtering and processing device and processing method for road construction. Through the mutual cooperation between the cylinder, the filter hole, the toothed ring, the spiral brush and the second gear, as the functional frame mechanism rotates, the second gear rotates. During the rotation of the second gear, multiple toothed rings can be driven to rotate at the same time, thereby rotating multiple cylinders.

[0027] The embodiment of the present invention further provides a dust filtering treatment method for road construction, using a dust filtering treatment device for road construction, and the specific method includes the following steps: Step 1: Clamp the clamping device 16 on the top of the road construction fence, wherein the clamping device 16 belongs to the prior art known to those skilled in the art, limit the processing barrel 1, and then start the air pump 13, through each suction pipe 2, the dust-containing air in the external surrounding is sucked into the processing barrel 1, and under the continuous impact of the airflow, the fan blade 83 located in the processing barrel 1 can be driven to rotate rapidly, and then the shaft 81 is driven to rotate, and the trapezoidal protrusion 85, the brush 86 and the second gear 87 rotate accordingly, and then the gas entering the processing barrel 1 flows upward, and at the same time, the external pump body is started to suck the external water into the liquid inlet pipe 5 3, and then flows into each annular tube 52, and finally sprayed downward through each nozzle 56, spraying to the surface of the polypropylene filler ball 4 below, wherein a plurality of polypropylene filler balls 4 together constitute a filler layer, and the arrangement of the filler layer increases the contact area between the air containing dust and the water, and the upward-flowing gas and the downward-sprayed water meet on the surface of the polypropylene filler ball 4 and the surrounding area, so that the water and the dust-containing air are fully contacted and mixed, and the dust particles in the air are adsorbed, intercepted and settled by the water in the process, and the dust is initially removed, and the settled dust is discharged to the outside through the drain pipe 10 along with the water; Step 2: At the same time, the droplets flowing downward intercept and capture the coarse particles contained in the gas, separate the coarse particles in the gas, and make the coarse particles flow out through the drain pipe 10 together with the droplets. The gas that has been initially filtered continues to flow upward, then passes through the conical filter plate 6, and then enters the cylinder 73 through the filter hole 74. In the process, the dust in the gas is further filtered under the action of the filter hole 74, and the dust is intercepted outside the cylinder 73; Step three, as the gas enters the processing barrel 1 through the suction pipe 2, the functional frame mechanism 8 is driven to work. During the working process of the functional frame mechanism 8, the rotating fan blades 83 are used to disturb the gas, so that the gas passes through the bearing mesh plate 3 evenly and enters between the several polypropylene filler balls 4. At the same time, the rotating brush 86 is used to push and scrape the upper surface of the conical filter mesh plate 6. The dust particles scraped on the conical filter mesh plate 6 eventually fall into the dust box 11 through the notch along the slope of the conical filter mesh plate 6. The sealing door on the right side of the dust box 11 is opened regularly to clean out the dust particles in the dust box 11. As the functional frame mechanism 8 works, the two trapezoidal protrusions 85 rotate. During the rotation of the two trapezoidal protrusions 85, they will pass through the top of the corresponding semicircular blocks 511 at the same time, pushing the two semicircular blocks 511 downward at the same time, and the spring 512 is compressed. The anti-blocking ring The assembly 57 is then pushed downward, and when the trapezoidal protrusion 85 is no longer in contact with the semicircular block 511, the semicircular block 511 returns to its original position under the elastic action of the spring 512, that is, the anti-blocking ring assembly 57 returns to its original position, and during the process, the soft brush 572 can be used to clean the nozzle 56 in time to prevent the nozzle 56 from being blocked by dust particles, so that water can be sprayed out normally through the nozzle 56. As the functional frame mechanism 8 works, the second gear 87 rotates, and during the rotation of the second gear 87, multiple gear rings 75 can be driven to rotate at the same time, thereby causing multiple cylinders 73 to rotate. During the rotation of the cylinder 73, the spiral brush 76 can clean the outer wall of the cylinder 73 in time to prevent dust from accumulating on the outer wall of the cylinder 73, thereby ensuring the normal filtering treatment of the gas by the filter cylinder mechanism 7, making the device run stably, and finally the filtered gas is discharged outward through the exhaust pipe 14.

10. A dust filtration treatment method for road construction, characterized in that: Using the dust filtering and processing device for road construction as described in any one of claims 1 to 9, the method comprises the following steps: Step 1: Clamp the clamping device on the top of the road construction fence, limit the processing barrel, and then start the air pump. Through each suction pipe, the dusty air around the outside is sucked into the processing barrel. The dusty air flows upward in the processing barrel. Start the external pump body to suck the external water into the spray mechanism. The spray mechanism guides the water into the processing barrel and sprays it downwards onto the surface of the polypropylene filler ball. The dusty air flowing upwards meets the water sprayed downwards on the surface and surrounding area of ​​the polypropylene filler ball, so that the water and the dusty air are fully contacted and mixed. In the process, the dust particles in the air are adsorbed, intercepted and settled by the water, and the dust is preliminarily removed. Step 2: At the same time, the water droplets flowing downward intercept and capture the coarse particles in the gas, and separate the coarse particles in the gas. The gas that has been initially filtered continues to flow upward, passes through the conical filter plate, and then enters the filter cartridge mechanism. Under the action of the filter cartridge mechanism, the dust in the gas is further filtered; Step three, as the gas enters the treatment barrel through the suction pipe, the fast-flowing gas drives the functional frame mechanism to work. During the operation of the functional frame mechanism, the gas is disturbed, so that the gas passes evenly through the load-bearing mesh plate and enters between several polypropylene filler balls. The working functional frame mechanism scrapes the upper surface of the conical filter mesh plate and drives the liquid spray mechanism and the filter cartridge mechanism for self-cleaning at the same time, so that the water is sprayed out normally and the gas flows upward normally through the filter cartridge mechanism. Finally, the filtered gas is discharged through the exhaust pipe.
