Description

Technical Field

[0001] The invention belongs to the technical field of high-speed construction dust removal, and in particular relates to a dust collection device for high-speed construction. Background Art

[0002] The construction process of the expressway involves processes such as earthwork excavation, road crushing, and asphalt paving. These processes will generate a large amount of dust, so it will involve the prevention and cleaning of general dirt such as dust. At present, dust collection devices are used at highway construction sites to prevent and clean general dirt such as dust. Among them, the more common dust collection device is a mobile vacuum truck, and most mobile vacuum trucks are equipped with high-efficiency fans for sucking dust. It will create a low-pressure area, thereby forming a negative pressure in the air around the vehicle. Due to the difference in air pressure, the surrounding air carrying dust particles is sucked into the vehicle's air intake. The inhaled air will first pass through a guiding system, which can reduce the speed of the airflow, so that the heavier particles will be thrown into the collection container due to inertia, while the lighter particles will continue to move forward with the airflow, thereby separating the particles and the air. After preliminary separation, the fine particles in the airflow will pass through the filter device, be further purified and discharged, thereby realizing dust collection.

[0003] However, the current dust collection device has some problems when used in a high-speed construction environment: because it is aimed at a high-speed construction environment, this environment will generate a large amount of dust. These high-concentration dust enters from the air intake port. When the particles and air are separated through the guiding system, the dust concentration is too high and the high-concentration dust gathers in the air. At this time, it cannot be guaranteed that all heavier particles will be thrown into the collection container under the action of inertia. Some of the heavier particles may continue to move forward with the lighter particles, resulting in the inability to completely separate the particles from the air, and eventually the agglomerated particles will clog the filter device.

DETAILED DESCRIPTION

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] See also Figure 1 - Figure 4 , this embodiment provides a dust collection device 2 for high-speed construction, comprising a fan 1 for sucking dust, a collection device 2 for guiding and collecting heavier dust particles, a dispersing device 3 and a filtering device 4 arranged in the collection device 2, the fan 1, the collection device 2 and the filtering device 4 are connected in sequence, the dispersing device 3 is used to disperse the dust particles that have condensed into a mass, the dust enters the collection device 2 through the fan 1, and the lighter dust particles are filtered through the filtering device 4; the collection device 2 here is a collection cylinder, and a guiding system is installed in the collection cylinder, which can reduce the speed of the airflow, so that the heavier particles will be thrown into the collection container due to inertia, while the lighter particles will continue to move forward with the airflow, thereby separating the particles from the air, and the filtering device 4 is a filter screen;

[0028] The scattering device 3 includes a support portion 5 arranged on the collecting device 2, a ratchet pawl portion 31, a crank rocker portion 32, a spring expansion portion 33 arranged on the support portion 5, a rotating shaft rocker portion 34 rotatably passing through the support portion 5, and a scattering portion 35. For the convenience of description, the rocker of the crank rocker portion 32 is represented by the first rocker 322, the ratchet pawl portion 31 is arranged on the support portion 5, and the rotating shaft 341 of the rotating shaft rocker portion 34 rotatably passes through the ratchet 311 The first end of the crank 321 of the crank rocker portion 32 is rotatably sleeved on the rotating shaft 341. The starting position of the crank 321 of the crank rocker portion 32 is located at the upper left corner. The ratchet 311 is the entire circle. Then, the crank 321 of the crank rocker portion 32 needs to be located at a quarter circle of the upper left corner of the ratchet 311 as the entire circle. The starting position of the first rocker 322 is inclined. The specific positions of the crank 321 and the first rocker 322 of the crank rocker portion 32 are as follows: Figure 2 and Figure 3 In the middle view, the ratchet pawl part 31 is actually located in one plane, and the crank rocker part 32 is located in another plane. The ratchet pawl part 31 and the crank rocker part 32 are not in the same plane, and there is a distance between the ratchet pawl part 31 and the crank rocker part 32, that is, the ratchet pawl part 31 and the crank 321 rocker do not contact each other, and there is no friction resistance. The pawl 312 of the ratchet pawl part 31 is arranged on one side of the second end of the crank 321, and the other side of the second end of the crank 321 is hinged to one end of the rocker of the crank rocker part 32, and the other end of the rocker of the crank rocker part 32 is connected to the spring expansion part 33, the breaking part 35 is arranged on the side wall of the first end of the crank 321, and the first end of the crank 321 is vertically provided with a guide part 36;

[0029] When the scattering device 3 moves, first, the shaft 341 of the shaft rocker part 34 is driven by the driving member, wherein the driving member is a motor, and the motor output shaft is connected to the shaft 341 of the shaft rocker part 34, the motor drives the shaft 341 to rotate, and the rocker of the shaft rocker part 34 is intermittently fitted with the guide part 36, and the rocker of the shaft rocker part 34 drives the crank 321 to rotate by fitting with the guide part 36, and the crank 321 drives the pawl 312 to move around the ratchet 311, and the rocker of the crank rocker part 32 drives the spring telescopic part 33 to move intermittently, and the spring rebound of the spring telescopic part 33 causes the crank 321 to quickly reset, and the crank 321 drives the scattering part 35 to rotate intermittently and quickly, so as to scatter the agglomerated dust particles. Figure 3As can be seen from the figure, the shaft 341 drives the rocker of the shaft rocker portion 34 to rotate clockwise, and the rocker of the shaft rocker portion 34 pushes the guide portion 36 to rotate clockwise, and at the same time the guide portion 36 drives the crank 321 to move synchronously, and in addition, the crank 321 also drives the pawl 312 to move along the ratchet 311, and the movement of the crank 321 drives the first rocker 322 to rotate clockwise, and the first rocker 322 pushes the spring of the spring expansion portion 33 to stretch. When the crank 321 rotates to the uppermost position perpendicular to the vertical direction, the crank 321 rotates faster due to the gravity of the crank 321 itself, and at this time the guide portion 36 is separated from the rocker of the shaft rocker portion 34. The crank 321 is pressed against the bottom surface of the spring expansion unit 33, and the spring of the spring expansion unit 33 is further stretched during the process. When the crank 321 rotates past the lowest position perpendicular to the vertical direction, the spring of the spring expansion unit 33 recovers its deformation. At this time, the spring reaction force drives the crank 321 to reset, completing a rapid movement of the crank 321. Here, the rapid reset of the spring of the spring expansion unit 33 enables the rapid movement of the crank 321, so that the crank 321 drives the breaking up unit 35 to rotate intermittently and rapidly, thereby breaking up the clumps of dust particles. In addition, the intermittent rapid movement of the crank 321 can not only break up the clumps of dust particles, but also save energy compared to continuous movement.

[0030] One thing that needs to be explained is that when dust is gathered into clumps, rapid rotation can effectively break up these dust clumps, allowing individual dust particles to be more easily carried away by the airflow. In addition, in the process of collecting dust, dust particles may carry static electricity due to friction. Static electricity can cause dust particles to attract each other and adhere to the equipment. Rapid rotation can help neutralize these electrostatic forces and reduce the adhesion of dust particles, thereby avoiding clogging of the subsequent filter device 4.

[0031] During the construction of expressways, processes such as earthwork excavation, road crushing, and asphalt paving are involved. These processes will generate a large amount of dust. At present, dust collection devices 2 are used at expressway construction sites to prevent and clean general dirt such as dust. Among them, the more common dust collection device 2 is a mobile dust suction vehicle, and most mobile dust suction vehicles are equipped with high-efficiency fans 1 for sucking dust. It will create a low-pressure area, thereby forming a negative pressure in the air around the vehicle. Due to the difference in air pressure, the surrounding air carrying dust particles is sucked into the vehicle's air intake. The inhaled air first passes through a guide system The system can reduce the speed of the airflow so that the heavier particles will be thrown into the collection container due to inertia, while the lighter particles will continue to move forward with the airflow, thereby separating the particles from the air. After preliminary separation, the fine particles in the airflow will pass through the filter device 4, be further purified and then discharged, thereby realizing dust collection. However, when the current dust collection device 2 is used in a high-speed construction environment, high-concentration dust will aggregate in the air, resulting in the inability to completely separate the particles from the air, and ultimately causing the agglomerated particles to clog the filter device 4.

[0032] In order to solve the above problems, in the present embodiment, a support part 5, a ratchet pawl part 31, a crank rocker part 32, a spring expansion part 33, a shaft rocker part 34 and a scattering part 35 are arranged in the collecting device 2, and then a motor is used to drive the shaft 341 of the shaft rocker part 34 to move, the shaft 341 drives the rocker of the shaft rocker part 34 to rotate clockwise, and the rocker of the shaft rocker part 34 pushes the guide part 36 to rotate clockwise, and at the same time the guide part 36 drives the crank 321 to move synchronously, and in addition the crank 321 also drives the pawl 312 to move along the ratchet 311, and the movement of the crank 321 drives the first rocker 322 to rotate clockwise, and the first rocker 322 pushes the spring of the spring expansion part 33 to stretch, and when the crank 321 rotates to the uppermost position perpendicular to the vertical direction, at this time due to the gravity of the crank 321 itself, The crank 321 rotates faster, at which time the guide portion 36 is disengaged from the rocker of the shaft rocker portion 34, and the spring of the spring expansion portion 33 is further stretched. When the crank 321 rotates past the lowest position perpendicular to the vertical direction, the spring of the spring expansion portion 33 recovers its deformation, and the spring reaction force drives the crank 321 to reset, completing a rapid movement of the crank 321. The rapid movement of the crank 321 is achieved by the rapid reset of the spring, so that the crank 321 drives the breaking up portion 35 to rotate intermittently and rapidly, thereby breaking up the condensed dust particles. This solves the problem that when the current dust collection device 2 is used in a high-speed construction environment, high-concentration dust aggregates in the air, resulting in the inability to completely separate the particles from the air, and ultimately causing the condensed particles to clog the filter device 4.

[0033] Since the crank 321 moves quickly by quickly returning to its original position through the spring of the spring expansion part 33, the crank 321 drives the breaking part 35 to rotate quickly and intermittently to break up the dust particles that have clumped together. Therefore, it is necessary to ensure that the breaking part 35 will not interfere with the ratchet 311, and it is necessary to ensure that the breaking part 35 can break up the dust particles that have clumped together. In this regard, in one embodiment, a connecting rod 37 is provided on the side wall of the first end of the crank 321. The length of the connecting rod 37 is greater than the diameter of the ratchet 311. By making the length of the connecting rod 37 greater than the diameter of the ratchet 311, it can be ensured that the dust particles are broken up. The part 35 will not interfere with the ratchet 311. In addition, taking into account the actual situation, a protective cover is provided on the outside of the scattering device 3 as a whole, which can prevent dust particles from directly entering the inside of the scattering device 3 and affecting the movement of its parts. The scattering part 35 is located outside the protective cover, and the scattering part 35 needs to face the dust particles directly to scatter the clumps of dust particles. In addition, the scattering part 35 is arranged on the connecting rod 37, and the pawl 312 is arranged on the second end of the crank 321 through a torsion spring. The torsion spring here acts to ensure that the pawl 312 can engage with the ratchet 311.

[0034] In order to allow the crank 321 to intermittently move quickly, in one embodiment, the spring telescopic portion 33 includes a movable rod 332 slidably arranged on the support portion 5 and a first spring 331 sleeved on the movable rod 332. The two ends of the first spring 331 are fixedly connected to the support portion 5 and the movable rod 332 respectively. The movable rod 332 is hinged to the rocker of the crank rocker portion 32. The first spring 331 here needs to take into account the overall weight of the crank 321, the guide portion 36, the pawl 312 and the first rocker 322 when designing. They need to be designed in coordination with each other to ensure that the crank 321 moves along the support portion 5. Figure 2 or Figure 3 When moving from the highest point to the lowest point, the stretching of the first spring 331 is within the deformation range of the first spring 331, and will not cause damage to the spring. In addition, when the crank 321 passes the lowest point, it is also necessary to ensure that the reset of the first spring 331 is sufficient to reset the crank 321, the guide portion 36, the pawl 312 and the first rocker 322 as a whole. Figure 2 location.

[0035] It is worth mentioning that when the dispersing part 35 disperses the dust particles that have clumped into a mass, since it is used in a high-speed construction environment and needs to be used for a long time, it is inevitable that some dust particles will stick to the dispersing part 35, and it is necessary to clean it after a period of time, otherwise the dispersing part 35 will not be effective in dispersing the dust particles that have clumped into a mass. In order to solve this problem, in one embodiment, the dispersing part 35 includes a plurality of arc-shaped blades 351 and a rotating block 352, and the plurality of arc-shaped blades 351 are evenly arranged on the outside of the rotating block 352, and the rotating block 352 is arranged on the connecting rod 37 through a rotating shaft. There are a plurality of connecting rods 37 and the dispersing part 35, and the number of connecting rods 37 corresponds to the number of the dispersing part 35. The arc-shaped blade 351 includes two arc-shaped pieces and a plurality of second springs 353, one of which is slidably arranged on the other arc-shaped piece, and a closed arc-shaped cavity is formed between the two arc-shaped pieces, and the plurality of second springs 353 are arranged in the arc-shaped cavity between the two arc-shaped pieces. First, the arc shape of the arc blade 351 itself can reduce the dust particles sticking to the scattering part 35. Secondly, the two arc pieces are connected to form an arc blade 351, and a closed arc cavity is formed between the two arc pieces. A number of second springs 353 are arranged in the arc cavity between the two arc pieces. The purpose of this design is that when the scattering part 35 moves, the arc blade 351 will vibrate, and the vibration force is transmitted to the second spring 353. Under the action of the second spring 353, the two arc pieces can be shaken. This shaking, combined with the arc action of the arc piece, makes the dust particles on the arc piece slide off, thereby further reducing the dust particles sticking to the scattering part 35. In addition, since the scattering part 35 is an intermittent rapid movement, this rapid movement will cause the arc blade 351 to vibrate instantaneously. This instantaneous vibration can cause greater shaking between the two arc pieces under the action of the second spring 353, which can better make the dust particles on the arc piece slide off.

[0036] Furthermore, since the rocker of the rotating shaft rocker portion 34 is intermittently in contact with the guide portion 36, there will be an impact force each time it is in contact with the guide portion 36. After long-term use, it is easy to be damaged or broken due to the concentrated force. In order to solve this problem, in one embodiment, the rotating shaft rocker portion 34 includes a rotating shaft 341 and a second rocker 342 vertically connected to the rotating shaft 341, and the length of the second rocker 342 is less than the length of the crank 321. The two ends of the second rocker 342 are different in size. The large end of the second rocker 342 is connected to the rotating shaft 341, and the small end of the second rocker 342 is connected to the guide portion 36. The design of a close fit with one end larger than the other can increase the end strength of the rod while keeping the overall weight light, so that it can withstand a larger load. In addition, the larger end can provide better support and stability, and the gradient design here helps to better distribute and transfer force, reducing damage or breakage caused by concentrated force. In addition, the guide portion 36 is a round rod, and a flexible sleeve is provided on the outside of the round rod to reduce impact. When the round rod contacts other objects, the flexible sleeve can act as a buffer to reduce the force generated by the impact, thereby further protecting the round rod and the impacted object from damage.

[0037] The working principle and use process of the present invention:

[0038] When in use, the fan 1 is first used to suck out the dust, which will create a low-pressure area, thereby forming a negative pressure in the air around the vehicle. Due to the difference in air pressure, the surrounding air carrying the dust particles is sucked into the air intake of the vehicle, and the sucked air enters the collection device 2. The motor drives the shaft 341 of the shaft rocker portion 34 to move, and the shaft 341 drives the rocker of the shaft rocker portion 34 to rotate clockwise. The rocker of the shaft rocker portion 34 pushes the guide portion 36 to rotate clockwise, and at the same time, the guide portion 36 drives the crank 321 to move synchronously. In addition, the crank 321 also drives the pawl 312 to move along the ratchet 311, and the movement of the crank 321 drives the first rocker 322 to rotate clockwise, and the first rocker 322 pushes the spring of the spring expansion portion 33 to stretch. When the crank 321 rotates to the uppermost position perpendicular to the vertical direction, the crank 321 rotates faster due to the gravity of the crank 321 itself. The guide portion 36 is disengaged from the rocker of the shaft rocker portion 34, and the spring of the spring expansion portion 33 is further stretched. When the crank 321 rotates to the lowest position perpendicular to the vertical direction, the spring of the spring expansion portion 33 recovers its deformation. At this time, the spring reaction force drives the crank 321 to reset, completing a rapid movement of the crank 321. Here, the rapid movement of the crank 321 is achieved by the rapid reset of the spring, so that the crank 321 drives the scattering portion 35 to rotate intermittently and rapidly, so that the condensed dust particles are dispersed. Then, the guiding system installed in the collecting cylinder can reduce the speed of the airflow, so that the heavier particles will be thrown into the collection container due to inertia, while the lighter particles will continue to move forward with the airflow, thereby separating the particles and the air. After preliminary separation, the fine particles in the airflow will pass through the filter device 4, be further purified and then discharged, thereby realizing dust collection.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
