Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to a highway asphalt paving protection device. Background Art

[0002] Asphalt roads have the advantages of low noise, good compression resistance and tensile strength, and can better adapt to unstable roadbeds. Asphalt needs to be heated before paving, and the heated asphalt will produce dust and toxic gases during the paving process.

[0003] At present, a Chinese patent discloses an asphalt pavement construction device for highway engineering (publication number CN216275113U). Although the above patent can suck the gap containing dust and toxic gas into the equipment for purification, the above patent sets the fan directly above the protective net, and the protective net cannot filter out the dust. The dust will pass through the fan, and some of the dust can easily be retained inside the fan, which will undoubtedly increase the operating burden and noise of the fan and increase the probability of fan failure.

[0004] Therefore, a highway asphalt paving protection device is proposed to solve the above problems. Utility Model Content

[0007] Preferably, the filtering device includes a water tank fixedly connected to the top of the air collecting hood, the top of the water tank is fixedly connected and communicated with an activated carbon filtering mechanism fixedly connected and communicated with the air pump, the interior of the water tank is filled with water, one end of the air duct passes through the water tank and extends to the interior of the water, before the mixed gas containing dust enters the air pump, the mixed gas must pass through the water inside the water tank, during this process, the dust in the mixed gas and some toxic gases that are easily soluble in water are adsorbed by the water, which not only effectively reduces the probability of solid or liquid impurities being retained inside the air pump, thereby reducing the operating burden and noise of the air pump, but also can reduce the content of toxic gases in the mixed gas, thereby reducing the operating burden of the subsequent plasma purifier.

[0008] Preferably, a dust filter fixedly connected to the water tank is fixedly connected to the surface of the air duct, and the dust filter is arranged inside the water, which can prevent dust from floating to the water surface, thereby improving the locking effect of water on dust.

[0009] Preferably, a grid plate is fixedly connected to the inside of the air duct, and the grid plate is arranged inside the water. The grid plate can break up bubbles generated when the mixed gas enters the water, thereby increasing the contact area between the mixed gas and the water, and further improving the adsorption effect of water on dust and toxic gases that are easily soluble in water.

[0010] Preferably, the surface of the water tank is fixedly connected and communicated with a drain valve, which enables the staff to easily discharge the waste water out of the water tank, so as to facilitate the staff to carry out maintenance work.

[0011] Preferably, the cross-sectional shape of the bottom wall of the water tank is sloped, and the lowest point of the drain valve connected to the water tank is connected to the lowest point of the bottom wall of the water tank, which can reduce the retention rate of wastewater inside the water tank to improve the treatment effect of the wastewater.

[0012] Preferably, the activated carbon filtering mechanism includes an installation box fixedly connected and connected to the top of the water tank, one end of the installation box is fixedly connected and connected to the air pump, and an activated carbon filter plate is placed inside the installation box. The activated carbon filter plate can absorb toxic gases and moisture that can be adsorbed by it in the mixed gas passing through, so that the mixed gas entering the air pump contains only a small amount of toxic gases, which effectively reduces the probability of solid or liquid impurities being retained inside the air pump, and further reduces the operating burden of the air pump.

[0013] Preferably, a grid is inserted into the interior of the installation box, and the activated carbon filter plate is inserted into the interior of the grid, adopting a detachable design, which can make it more convenient for the staff to remove the activated carbon filter plate, so as to facilitate the staff to carry out subsequent maintenance operations.

[0014] Preferably, a sealing ring in contact with the installation box is provided on the surface of the grid, and the sealing ring is arranged above the connection point between the air pump and the installation box.

[0016] 1. Before the mixed gas containing dust enters the air pump, the mixed gas must pass through the water inside the water tank. During this process, the dust in the mixed gas and some toxic gases that are easily soluble in water are adsorbed by water, which not only effectively reduces the probability of solid or liquid impurities being retained inside the air pump, thereby reducing the operating burden and noise of the air pump, but also can reduce the content of toxic gases in the mixed gas, thereby reducing the operating burden of the subsequent plasma purifier;

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-4As shown, a highway asphalt paving protection device includes: a mounting frame 1, one end of the mounting frame 1 is fixedly connected to an air collecting hood 2, the top of the air collecting hood 2 is fixedly connected and connected to an air duct 3, one end of the air duct 3 is fixedly connected and connected to an air pump 4, one end of the air pump 4 is fixedly connected and connected to a plasma purifier 5; a filtering device 6, the filtering device 6 is fixedly connected and connected between the air duct 3 and the air pump 4.

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, the filtering device 6 includes a water tank 61 fixedly connected to the top of the air collecting hood 2, the top of the water tank 61 is fixedly connected and communicated with an activated carbon filtering mechanism 65 fixedly connected and communicated with the air pump 4, the interior of the water tank 61 is filled with water, one end of the air duct 3 passes through the water tank 61 and extends to the interior of the water; the surface of the air duct 3 is fixedly connected with a dust filter 62 fixedly connected to the water tank 61, and the dust filter 62 is arranged inside the water; the interior of the air duct 3 is fixedly connected with a grid plate 63, and the grid plate 63 is arranged inside the water; the surface of the water tank 61 is fixedly connected and communicated with a drain valve 64; the cross-sectional shape of the inner bottom wall of the water tank 61 is sloped, and the lowest point of the connection between the drain valve 64 and the water tank 61 is communicated with the lowest point of the inner bottom wall of the water tank 61.

[0026] like Figure 3 As shown, the activated carbon filtering mechanism 65 includes an installation box 651 fixedly connected and connected to the top of the water tank 61, one end of the installation box 651 is fixedly connected and connected to the air pump 4, an activated carbon filter plate 652 is placed inside the installation box 651; a grid 653 is inserted into the interior of the installation box 651, and the activated carbon filter plate 652 is inserted into the interior of the grid 653; the surface of the grid 653 is provided with a sealing ring 654 in contact with the installation box 651, and the sealing ring 654 is arranged above the connection point between the air pump 4 and the installation box 651.

[0027] When it is necessary to protect the dust and toxic gases generated by asphalt paving, the staff only needs to manually turn on the air pump 4, and the air pump 4 quickly sucks the air inside the water tank 61 through the activated carbon filter mechanism 65. At this time, negative pressure is generated inside the water tank 61, and the outside air entrains dust and toxic gases to form a mixed gas, which is sucked into the water tank 61 along the gas collecting hood 2 and the air duct 3. When the mixed gas enters the interior of the water tank 61 through the air duct 3, the mixed gas is introduced into the water, and the dust and some toxic gases that are easily soluble in water in the mixed gas are adsorbed by the water, and then the preliminarily filtered mixed gas enters the installation box 651 along the water tank 61 In the process of passing through the installation box 651, the activated carbon filter plate 652 absorbs the toxic gas and moisture in the mixed gas that can be adsorbed by it, so that the mixed gas entering the air pump 4 contains only a small amount of toxic gas, which effectively reduces the probability of solid or liquid impurities being retained inside the air pump 4, thereby reducing the operating burden and noise of the air pump 4. Finally, the mixed gas containing a small amount of toxic gas enters the plasma purifier 5 for deep purification, making the gas discharged to the outside safer and cleaner, and effectively reducing the probability of dust and toxic gases generated by asphalt paving affecting the health of pedestrians and workers.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
