Description

Technical Field

[0001] The invention relates to the field of road construction, and in particular to a dust suppression device for road engineering construction. Background Art

[0002] Dust suppression devices for road engineering construction refer to equipment or facilities specially designed and used during the construction of road engineering in order to effectively reduce dust pollution generated by construction activities, reduce the concentration of particulate matter in the air, and protect the health of construction workers and the quality of the surrounding environment.

[0003] In the road construction environment, after using water spray to reduce dust, the dust settles to the ground with the water mist. After drying, the dust still exists on the ground. At this time, if a vehicle or person passes by, the dust on the ground will be raised again, so that the dust still exists in the road construction environment. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a dust suppression device for road engineering construction.

[0005] The present invention provides a dust suppression device for road engineering construction, comprising a mobile base and further comprising:

[0006] A housing fixed to the top of the mobile base;

[0007] A water tank, fixed inside the mobile base;

[0008] A dust suppression component is installed inside the mobile base;

[0009] The dust reduction assembly includes an exhaust mechanism and a spray mechanism;

[0010] The exhaust mechanism is used to impact the air flow to the position below the movable base, so as to drive the dust to be lifted and enter the interior of the housing;

[0011] The spray mechanism is used to spray the water in the water tank in atomized form to settle the dust entering the interior of the housing, and the settled dust falls into the water tank;

[0012] When dust reduction is required in the construction environment, the mobile base moves in the environment where dust reduction is required to drive the shell to move. During the movement of the shell, the exhaust mechanism transports airflow to the bottom of the shell, so that the airflow impacts the dust on the ground, lifts the dust on the ground, and the lifted dust enters the interior of the shell. Then the dust flows along the path of the airflow inside the shell, and the flowing airflow drives the dust to enter the range of the spray mechanism. Then water mist is sprayed through the spray mechanism to settle the dust mixed in the airflow, so that the dust settles in the water tank and falls into the water. On the one hand, by lifting the dust on the ground, the dust settled on the ground can be cleaned, which is beneficial to reduce the dust raised by vehicles or people passing by, so as to achieve dust reduction in the road engineering construction environment. On the other hand, the lifted dust is settled in the water tank inside the shell, so that the lifted dust will not fall back to the ground, which is beneficial to avoid dust being raised again after the dust is dried.

[0013] Preferably, the exhaust mechanism comprises:

[0014] An installation compartment, fixed inside the housing;

[0015] An air pump, fixed inside the installation bin;

[0020] A guide bucket fixed to the input end of the air pump;

[0021] The first filter is fixed inside the installation bin and is located below the guide bucket. After the air pump is started, it drives the airflow to flow. The airflow flows out along the air pump and flows along the path of the connecting bin and the first connecting pipe, the air diffuser, and the first exhaust port, so that the airflow flows toward the ground along the arc trajectory of the first exhaust port, driving the dust on the ground to be lifted. At the same time, the input end of the air pump drives the airflow into the installation bin and then enters the air pump through the first filter and the guide bucket, so that the airflow forms a mobile cycle. During the circulation process, the dust is lifted and driven into the interior of the inner bin, and then the dust is driven to settle under the action of the spray mechanism. The airflow passes through the first filter, thereby settling the dust to clean the dust deposited on the ground, which is beneficial to reduce the occurrence of dust caused by vehicles and people passing by.

[0022] Preferably, the exhaust mechanism further comprises:

[0023] A plurality of groups of partition plates, wherein a plurality of the partition plates form a group, and a group of the partition plates is fixed inside one of the air diffusers to evenly disperse and guide the airflow toward the first air outlet;

[0026] A first guide plate is fixed inside the mobile base, an inner chamber is formed between an inner wall of the first guide plate and an outer wall of the installation chamber, and the water tank is arranged inside the inner chamber;

[0034] A plurality of atomizing nozzles are fixedly connected to the top of each of the water pipes;

[0035] The water pump drives the water in the water tank to flow along the water pipe into the atomizing nozzle, and then the water is atomized and sprayed out through the atomizing nozzle. After the atomized water mist reaches the inner bin, it will enter the inner bin along with the airflow, thereby settling the dust brought in by the airflow, so that the settled dust falls into the water tank, which is beneficial to avoid the situation where the settled dust falls on the ground and dries and then is raised again. The setting of the second filter isolates the dust settled on the water surface of the water tank from the water pump, which is beneficial to avoid the situation where the settled dust enters the water pump and causes blockage.

[0036] Preferably, the exhaust mechanism further comprises:

[0039] When the airflow passes through the interior of the installation bin, it drives the fan blades to rotate, and the fan blades drive the scraper to rotate. The scraper scrapes the dust accumulated at the bottom of the first filter, which helps to avoid the situation where the wet dust after passing through the water mist is blocked at the position of the first filter and affects the airflow.

[0040] Preferably, the exhaust mechanism further comprises:

[0041] A plurality of second air outlets are fixed to the bottom of the mobile base in a circular array;

[0043] The second air outlet is arranged at the bottom edge of the first guide plate and is connected to the connecting bin through the second connecting pipe, so that the air enters and flows along the second connecting pipe to the second air outlet and then is discharged. The airflow discharged from the second air outlet flows along the bottom of the first guide plate, which is beneficial to avoid the raised dust from entering the bottom of the movable base and causing obstruction, and is beneficial to promoting the airflow to drive all the dust into the airflow channel between the first guide plate and the second guide plate, thereby facilitating the sufficient sedimentation of the dust.

[0048] The rotation of the scraper drives the stirring blade to rotate. The rotation of the stirring blade drives the water in the water tank to flow. The flow of water drives the dust deposited on the water surface to flow, so that the dust flows through the guide inclined plate into the dust hopper. The dust is collected inside the dust hopper, and the water flows along the side wall of the dust hopper, which is conducive to collecting the dust and preventing the accumulation of dust on the water surface, causing the water level to rise and submerge the air inlet.

[0049] Preferably, it also includes:

[0050] A connection box is fixed to the bottom of the dust collecting hopper, and the connection box passes through the water tank and the mobile base;

[0051] A collection box, fixed to the bottom of the mobile base and connected to the bottom of the connection box;

[0058] A cylinder is fixed on the inner wall of the installation bin, and the cylinder drives the rack to move vertically through the telescopic end, and when the rack moves upward to the top, it hinders the rotation of the scraper;

[0059] After the cylinder is started, it drives the rack to move vertically, and the rack moves vertically to drive the gear to rotate. After the gear rotates, it drives the flip plate to flip. After the flip plate flips, the top of the connecting box is exposed, allowing dust to pass through the connecting box. At the same time, when the rack moves upward, it can block the scraper, thereby hindering the rotation of the stirring blade and stopping the water flow. This is beneficial to avoid a large amount of water flowing into the dust collecting hopper and then entering the collection box, so as to slow down the loss of water flow.

DETAILED DESCRIPTION

[0071] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0072] like Figures 1 to 8 The dust suppression device for road engineering construction shown comprises a mobile base 1 and also comprises:

[0073] The housing 101 is fixed on the top of the mobile base 1;

[0074] A water tank is fixed inside the mobile base 1;

[0075] A dust suppression component is installed inside the mobile base 1;

[0076] The dust suppression component includes an exhaust mechanism and a spray mechanism;

[0077] The exhaust mechanism is used to impact the air flow to the position below the mobile base 1 to drive the dust to be lifted and enter the interior of the housing 101;

[0078] The spray mechanism is used to spray the water 5 in the water tank in an atomized form to settle the dust entering the housing 101, and the settled dust falls into the water tank;

[0079] In the road construction environment, after spraying water to reduce dust, the dust settles to the ground with the water mist, and the dust still exists on the ground after drying. At this time, if a vehicle or person passes by, the dust on the ground will be raised again, so that the dust still exists in the road construction environment;

[0080] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: when it is necessary to reduce dust in the construction environment, the mobile base 1 moves in the environment where dust reduction is required to drive the shell 101 to move. During the movement of the shell 101, the exhaust mechanism conveys airflow to the bottom of the shell 101, so that the airflow impacts the dust on the ground, lifts the dust on the ground, and the lifted dust enters the interior of the shell 101. Then the dust flows along the path of the airflow inside the shell 101, and the flowing airflow drives the dust to enter the range of the spray mechanism. Then, water mist is sprayed through the spray mechanism to settle the dust mixed in the airflow, so that the dust settles in the water tank and falls into the water. On the one hand, by lifting the dust on the ground, the dust settled on the ground can be cleaned, which is beneficial to reduce the dust raised when vehicles or people pass by, so as to achieve dust reduction in the road construction environment. On the other hand, the lifted dust is settled in the water tank inside the shell 101, so that the lifted dust will not fall back to the ground, which is beneficial to avoid the dust from being raised again after drying.

[0087] A plurality of first air outlets 2 are respectively fixed at the bottom of each air diffuser 201, and the first air outlets 2 are arranged in an arc shape, with the opening facing the middle of the bottom of the mobile base 1;

[0088] A guide bucket 403 is fixed to the input end of the air pump 204;

[0089] The first filter screen 405 is fixed inside the installation bin 203 and is located below the guide bucket 403;

[0090] After the air pump 204 is started, it drives the air flow, and the air flow flows out along the air pump 204, flows along the path of the connecting bin 205 and the first connecting pipe 202, the air diffuser 201, and the first exhaust port 2, so that the air flow flows toward the ground along the arc trajectory of the first exhaust port 2, driving the dust on the ground to be lifted. At the same time, the input end of the air pump 204 drives the air flow into the installation bin 203 and then enters the air pump 204 through the first filter 405 and the guide bucket 403, so that the air flow forms a moving cycle. During the circulation process, the dust is lifted and driven into the interior of the inner bin 402, and then the dust is driven to settle under the action of the spray mechanism, and the air flow passes through the first filter 405, thereby settling the dust to achieve the cleaning of the dust deposited on the ground, which is beneficial to reduce the occurrence of dust caused by vehicles and personnel passing by.

[0098] A connecting cavity is formed between the first guide plate 4 and the second guide plate 401. The dust raised from the ground first enters the interior of the connecting cavity under the guidance of the arc-shaped bottom of the first guide plate 4, and then enters the interior of the inner warehouse 402 along the connecting point between the connecting cavity and the inner warehouse 402. The internal spray mechanism of the inner warehouse 402 settles the dust in the airflow, and then the airflow passes through the inner warehouse 402 and enters the interior of the installation warehouse 203 along the air inlet 404, so that the airflow can flow under the guidance of the curved airflow channel formed by the connecting warehouse and the inner warehouse 402, so that the airflow can flow smoothly to the interior of the inner warehouse 402.

[0104] The water pump 502 drives the water flow in the water tank along the water pipe 503 into the atomizing nozzle 504, and then the water is atomized and sprayed out through the atomizing nozzle 504. After the atomized water mist reaches the inner warehouse 402, it will enter the inner warehouse 402 along with the airflow, thereby settling the dust brought in by the airflow, so that the settled dust falls into the water tank, which is beneficial to avoid the settled dust falling on the ground and drying and then being raised again.

[0108] When the airflow passes through the interior of the installation bin 203, it drives the fan blades 6 to rotate. After the fan blades 6 rotate, they drive the scraper 601 to rotate. After the scraper 601 rotates, it scrapes the dust accumulated at the bottom of the first filter 405, thereby preventing the damp dust after passing through the water mist from clogging the first filter 405 and affecting the airflow.

[0127] The cylinder 1003 is fixed on the inner wall of the installation chamber 203. The cylinder 1003 drives the rack 1002 to move vertically through the telescopic end. When the rack 1002 moves upward to the top, it blocks the rotation of the scraper 601.

[0128] After the cylinder 1003 is started, it drives the rack 1002 to move vertically. After the rack 1002 moves vertically, it drives the gear 1001 to rotate. After the gear 1001 rotates, it drives the flip plate 10 to flip. After the flip plate 10 flips, the top of the connecting box 9 is exposed, allowing dust to pass through the connecting box 9. At the same time, when the rack 1002 moves upward, it can block the scraper 601, thereby hindering the rotation of the stirring blade 8, so that the water flow stops flowing, which is beneficial to avoid a large amount of water flow entering the dust hopper 902 and then entering the collection box 901, so as to reduce the loss of water flow.

[0129] The working principle of the present invention is as follows: when it is necessary to reduce dust in the construction environment, the mobile base 1 moves in the environment where dust reduction is required to drive the shell 101 to move. During the movement of the shell 101, the exhaust mechanism conveys airflow to the bottom of the shell 101, so that the airflow impacts the dust on the ground, lifts the dust on the ground, and the lifted dust enters the interior of the shell 101. Then the dust flows along the path of the airflow inside the shell 101, and the flowing airflow drives the dust to enter the range of the spray mechanism. Then, water mist is sprayed through the spray mechanism to settle the dust mixed in the airflow, so that the dust settles in the water tank and falls into the water. On the one hand, by lifting the dust on the ground, the dust settled on the ground can be cleaned, which is beneficial to reduce the dust raised by vehicles or people passing by, so as to achieve dust reduction in the road engineering construction environment. On the other hand, the lifted dust is settled in the water tank inside the shell 101, so that the lifted dust will not fall back to the ground, which is beneficial to avoid dust being raised again after drying.

[0130] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
