Description

Technical Field

[0001] This invention relates to the technical field of dust removal equipment, specifically a dust absorption device for construction. Background Technology

[0002] With the acceleration of urbanization and the booming development of the construction industry, construction dust pollution has become an increasingly prominent problem. The construction process generates a large amount of dust, which not only seriously affects the air quality at construction sites but also poses a significant threat to the health of construction workers. For example, dust can irritate the skin, corneas, and oral mucosa of construction workers, and long-term inhalation can lead to occupational diseases such as pneumoconiosis.

[0003] Most existing dust absorption devices for construction first use a vacuum cleaner to collect the dust and then spray it to prevent the dust in the suction device from being stirred up again when workers collect it. However, the existing spraying method is mostly continuous during the vacuuming process, which not only wastes water resources. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a dust absorption device for construction, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust absorption device for construction, comprising a trolley, a device shell fixedly connected to the top outer wall of the trolley, a heat dissipation and ventilation hole provided on the outer wall of the device shell, a controller fixedly connected to the outer wall of the device shell, a ventilation pipe fixedly connected to the top outer wall of the device shell, a dust collection bin fixedly connected to the outer wall of the trolley, a dust collection pipe fixedly connected to the outer wall of the dust collection bin, a water tank fixedly connected to the inner wall of the device shell, an intermittent spray device with water-saving function provided on the outer wall of the water tank, an accelerated filtration device provided inside the dust collection bin, a motor fixedly connected to the bottom inner wall of the device shell, a drive shaft fixedly connected to the output end of the motor, an air intake fan fixedly connected to the outer wall of the drive shaft, a circulating water pipe fixedly connected to the bottom outer wall of the water tank, and the other end of the circulating water pipe fixedly connected to the bottom inner wall of the dust collection bin; The intermittent spraying device includes a squeezing rod, a transmission ramp, a squeezing spring, a fixed plate, a connecting rod, a baffle, a booster pump, a water outlet pipe, an atomizer, a first striking ramp, a first striking spring, a striking plate, a short rod, a second striking ramp, a second striking spring, and a Z-shaped rod. The squeezing rod is fixedly connected to the outer wall of the transmission shaft, and the transmission ramp is slidably connected to the outer wall of the water tank. When the device is started, the motor drives the squeezing rod to rotate, thereby squeezing the transmission ramp. The transmission ramp is squeezed, which drives the connecting rod to move downward. When the connecting rod moves downward, it will drive the baffle to move downward. Through the booster pump, water flows from the water outlet pipe into the atomizer to start the spraying operation.

[0009] According to the above technical solution, the filter plate is slidably connected to the inner wall of the dust collection bin, the downward pressure block is fixedly connected to the top outer wall of the filter plate, one end of the downward pressure spring is fixedly connected to the outer wall of the filter plate, the arc-shaped plate is fixedly connected to the inner wall of the dust collection bin, and the other end of the downward pressure spring is fixedly connected to the top outer wall of the arc-shaped plate.

[0010] According to the above technical solution, one end of the upper pressure spring is fixedly connected to the bottom outer wall of the arc-shaped plate, the activated carbon plate is fixedly connected to the other end of the upper pressure spring, the upper pressure inclined block is fixedly connected to the bottom outer wall of the activated carbon plate, and the upper pressure rod is fixedly connected to the outer wall of the L-shaped rod. When the Z-shaped rod moves towards the atomizer, it will drive the L-shaped rod to move in the same direction. The L-shaped rod drives the lower pressure rod to squeeze the lower pressure inclined block, thereby causing the filter plate to move downward together. After the Z-shaped rod completes the striking operation, the L-shaped rod moves away from the dust collection bucket together with the Z-shaped rod, the squeezing of the lower pressure inclined block is released, and the lower pressure spring drives the filter plate to reset.

[0011] According to the above technical solution, the inner wall of the dust collection bin is provided with an anti-wall-hanging device, which includes a hinge rod, a cleaning rod, a squeezing column, a rotating shaft, a rotating groove, a connecting sleeve, a striking rod, a return spring, and a filter plate. One end of the hinge rod is hinged to the top outer wall of the filter plate.

[0012] According to the above technical solution, the cleaning rod is hinged to the other end of the hinge rod, the air filter plate is fixedly connected to the inner wall of the dust collection bucket, the cleaning rod is slidably connected to the bottom outer wall of the air filter plate, the squeezing column is fixedly connected to the outer wall of the cleaning rod, and the connecting sleeve is fixedly connected to the inner wall of the dust collection bucket.

[0014] This invention provides a dust absorption device for construction. It has the following beneficial effects: 1. This invention incorporates an intermittent spraying device. When activated, the motor drives the extrusion rod to rotate, thus compressing the transmission inclined block. The compressed transmission inclined block causes the connecting rod to move downwards. This downward movement of the connecting rod causes the baffle to move downwards, allowing water to flow from the outlet pipe into the atomizer via a booster pump, initiating spraying. When the extrusion rod leaves the inclined block, the baffle returns to the outlet pipe. This reciprocating motion of the baffle completes the intermittent spraying effect, solving the problem of water waste caused by continuous spraying. Furthermore, the downward movement of the connecting rod compresses and strikes the first striking inclined block, causing the short rod to move towards the second striking inclined block. When the second striking inclined block is compressed, it causes the Z-shaped rod to move towards the atomizer, thus striking the atomizer. This reciprocating striking motion of the Z-shaped rod solves the problem of the atomizer being clogged by impurities and dust in the water, affecting atomization efficiency.

[0015] 2. This invention incorporates an accelerated filtration device. When the Z-shaped rod moves towards the atomizer, it drives the L-shaped rod to move in the same direction. The L-shaped rod then drives the pressure bar to press against the pressure block, causing the filter plate to move downwards. After the Z-shaped rod completes its striking action, the L-shaped rod moves away from the dust collection bin along with the Z-shaped rod. The pressure on the pressure block is released, and the pressure spring resets the filter plate. This reciprocating motion of the filter plate achieves a vibration effect, solving the problem of slow dust and sludge flow on the filter plate, which leads to excessive dust and sludge accumulation. This addresses several issues affecting filtration efficiency. When the L-shaped rod moves downwards to press the inclined block, the upper rod moves upwards towards the inclined block. The upper inclined block is compressed and moves upwards, causing the activated carbon plate to move upwards as well. Simultaneously, the activated carbon plate and the filter plate approach each other. This compression of space compresses the dust and sludge, improving the separation of water and dust. The separated water flows through the activated carbon plate to the bottom of the dust collection bin and is then re-inhaled into the water tank via the circulating water pipe. This solves the problem of difficult separation of sludge and water, while also conserving water resources and improving water utilization.

[0016] 3. This invention incorporates an anti-wall-sticking device. When the filter plate moves downwards, it pulls the hinge rod downwards as well, causing the cleaning rod to move to both sides of the filter plate to achieve the cleaning effect. This solves the problem that dust adheres to the bottom of the filter plate due to increased adhesion from contact with water mist, thus reducing dust collection efficiency. Simultaneously, when the cleaning rod moves to both sides, it drives the extrusion column to slide within the rotating groove, causing the rotating shaft to be compressed and rotate within the connecting sleeve. When the rotating shaft rotates, it drives the striking rod to rotate, causing the striking rod to strike the outer wall of the filter plate. Furthermore, a reset spring prevents the striking rod from jamming, thus solving the problem of dust and mud accumulation in corners around the filter plate that cannot be cleaned by the cleaning rod.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8One embodiment of the present invention is as follows: a dust absorption device for construction, comprising a trolley 1, a device shell 2 fixedly connected to the top outer wall of the trolley 1, a heat dissipation and ventilation hole 3 provided on the outer wall of the device shell 2, a controller 4 fixedly connected to the outer wall of the device shell 2, a ventilation pipe 5 fixedly connected to the top outer wall of the device shell 2, a dust collection bucket 14 fixedly connected to the outer wall of the trolley 1, a dust collection pipe 6 fixedly connected to the outer wall of the dust collection bucket 14, a water tank 13 fixedly connected to the inner wall of the device shell 2, an intermittent spray device 7 with water-saving function provided on the outer wall of the water tank 13, and a motor 10 fixedly connected to the bottom inner wall of the device shell 2. The output end is fixedly connected to a drive shaft 11, and an air intake fan 12 is fixedly connected to the outer wall of the drive shaft 11. A circulating water pipe 15 is fixedly connected to the bottom outer wall of the water tank 13, and the other end of the circulating water pipe 15 is fixedly connected to the bottom inner wall of the dust collection bin 14. The intermittent spray device 7 includes a squeezing rod 71, a drive ramp 72, a squeezing spring 73, a fixing plate 74, a connecting rod 75, a baffle 76, a booster pump 77, a water outlet pipe 78, an atomizer 79, a first striking ramp 710, a first striking spring 711, a striking plate 712, a short rod 713, a second striking ramp 714, a second striking spring 715, and a Z-shaped... Rod 716, extrusion rod 71 are fixedly connected to the outer wall of drive shaft 11, drive ramp 72 is slidably connected to the outer wall of water tank 13, one end of extrusion spring 73 is fixedly connected to the outer wall of drive ramp 72, fixing plate 74 is fixedly connected to the other end of extrusion spring 73, connecting rod 75 is fixedly connected to the outer wall of drive ramp 72, baffle 76 is fixedly connected to the outer wall of connecting rod 75, booster pump 77 is fixedly connected to the outer wall of device housing 2, water outlet pipe 78 passes through and connects the outer walls of water tank 13 and dust collection bin 14, atomizer 79 is fixedly connected to the outer wall of water outlet pipe 78, and striking ramp 710 is slidably connected to... One end of the striking spring 711 is fixedly connected to the outer wall of the top outer wall of the water tank 13, the striking plate 712 is fixedly connected to the other end of the striking spring 711, the short rod 713 is fixedly connected to the outer wall of the striking block 710, the second striking block 714 is slidably connected to the top outer wall of the water tank 13, one end of the striking spring 715 is fixedly connected to the outer wall of the second striking block 714, the other end of the striking spring 715 is fixedly connected to the inner wall of the device housing 2, and the Z-shaped rod 716 is fixedly connected to the outer wall of the second striking block 714 and penetrates the outer wall of the device housing 2 and the dust collection bucket 14.

[0021] When the device is started, the motor 10 drives the extrusion rod 71 to rotate, thereby extruding the transmission inclined block 72. The transmission inclined block 72 is extruded, which drives the connecting rod 75 to move downward. When the connecting rod 75 moves downward, it will drive the baffle 76 to move downward. Through the booster pump 77, water flows from the water outlet pipe 78 into the atomizer 79 to start spraying. When the extrusion rod 71 leaves the transmission inclined block 72, the baffle 76 returns to the water outlet pipe 78. The reciprocating motion of the baffle 76 completes the intermittent spraying effect, which solves the problem of water waste caused by continuous spraying of the atomizer 79. When the connecting rod 75 moves downward, it will squeeze and strike the first wedge block 710, thereby driving the short rod 713 to move towards the second wedge block 714. When the second wedge block 714 is squeezed, it will drive the Z-shaped rod 716 to move towards the atomizer 79, thus completing the striking action on the atomizer 79. Through the reciprocating striking motion of the Z-shaped rod 716, the problem of the atomizer 79 being blocked by impurities and dust in the water, thus affecting the atomization efficiency, is solved.

[0022] In this example, when vacuuming is required, the trolley 1 is first pushed to the desired vacuuming location. Then, the motor 10 and drive shaft 11 are activated, rotating the suction fan 12 and transmitting suction power to the suction pipe 6. The suction pipe 6 absorbs dust and draws it into the dustbin 14. The atomizer 79 sprays water mist to wet the dust. Due to the water mist, the dust's gravity increases, causing it to fall onto the filter plate 84. The filter plate 84 then performs preliminary filtration before entering the top of the activated carbon plate 88. At this point, the dust and sludge pass through the activated carbon plate 88 due to gravity, and the activated carbon plate 88 effectively isolates the dust. The water, filtered by the activated carbon plate 88, enters the bottom of the dustbin 14 and is absorbed by the circulating water pipe 15 and re-injected into the water tank 13. The water in the water tank 13 is then re-injected into the atomizer 79 through the water outlet pipe 78, thus completing the water circulation. When the drive shaft 11 rotates, it will drive the extrusion rod 71 to rotate as well, thereby extruding the drive inclined block 72. The extrusion rod 72 is compressed, which in turn compresses the extrusion spring 73 and moves it towards the fixed plate 74. The drive inclined block 72 drives the connecting rod 75 to move downwards, and the connecting rod 75 drives the baffle 76 to move downwards, thereby completely opening the water inlet of the water outlet pipe 78. Water flows through the booster pump 77 and the outlet pipe 78 into the atomizer 79. When the squeeze rod 71 leaves the drive ramp 72, the squeeze spring 73 drives the drive ramp 72 to reset and, through the connecting rod 75, drives the baffle 76 to block the inlet of the outlet pipe 78 again. The intermittent water injection is completed by the up-and-down reciprocating motion of the baffle 76. When the connecting rod 75 moves downward, it will squeeze the striking ramp 710. The striking ramp 710 is squeezed, which compresses the striking spring 711 and moves it towards the striking plate 712. When the striking ramp 710 moves towards the striking plate 712, it will drive the short The rod 713 moves together towards the striking plate 712, causing the short rod 713 to press and strike the second striking block 714. The second striking block 714 is compressed, thereby compressing the second striking spring 715 and moving it towards the dust collection bin 14. When the second striking block 714 moves towards the dust collection bin 14, it will drive the Z-shaped rod 716 to move towards the dust collection bin 14, thereby enabling the Z-shaped rod 716 to complete the striking effect on the atomizer 79. Through the up-and-down reciprocating motion of the connecting rod 75, the Z-shaped rod 716 can repeatedly strike, solving the problem that the atomizer 79 is blocked by impurities and dust in the water, thus affecting the atomization efficiency.

[0023] Please see Figures 1-8Based on the above embodiments, another embodiment of the present invention is as follows: an accelerated filtration device 8 is provided inside the dust collection bin 14, and an anti-stubble device 9 is provided on the inner wall of the dust collection bin 14. The accelerated filtration device 8 includes an L-shaped rod 81, a downward pressing rod 82, a downward pressing inclined block 83, a filter plate 84, a downward pressing spring 85, an arc-shaped plate 86, an upward pressing spring 87, an activated carbon plate 88, an upward pressing inclined block 89, and an upward pressing rod 810. The L-shaped rod 81 is fixedly connected to the outer wall of the Z-shaped rod 716, the downward pressing rod 82 is fixedly connected to the outer wall of the L-shaped rod 81, and the filter plate 84 is slidably connected to the dust collection bin 14. The inner wall of the dust bin 14 is connected to the top outer wall of the filter plate 84 by a downward pressure block 83, one end of a downward pressure spring 85 is fixedly connected to the outer wall of the filter plate 84, an arc-shaped plate 86 is fixedly connected to the inner wall of the dust bin 14, the other end of the downward pressure spring 85 is fixedly connected to the top outer wall of the arc-shaped plate 86, one end of an upward pressure spring 87 is fixedly connected to the bottom outer wall of the arc-shaped plate 86, an activated carbon plate 88 is fixedly connected to the other end of the upward pressure spring 87, an upward pressure block 89 is fixedly connected to the bottom outer wall of the activated carbon plate 88, and an upward pressure rod 810 is fixedly connected to the outer wall of the L-shaped rod 81.

[0024] When the Z-shaped rod 716 moves toward the atomizer 79, it will drive the L-shaped rod 81 to move in the same direction. The L-shaped rod 81 drives the pressing rod 82 to squeeze the pressing block 83, thereby causing the filter plate 84 to move downward together. After the Z-shaped rod 716 completes the striking operation, the L-shaped rod 81 moves away from the dust collection bucket 14 along with the Z-shaped rod 716. The compression of the pressing block 83 is released, and the pressing spring 85 drives the filter plate 84 to reset. The up-and-down reciprocating motion of the filter plate 84 makes the filter plate 84 vibrate, which solves the problem that the dust and mud flow slowly on the filter plate 84, resulting in excessive accumulation of dust and mud on the filter plate 84 and affecting the filtration effect. Furthermore, when the L-shaped rod 81 moves downward to press the inclined block 83, the upper pressing rod 810 moves upward to press the inclined block 89. The upper inclined block 89 is squeezed and moves upward, which in turn drives the activated carbon plate 88 to move upward. At the same time, the activated carbon plate 88 and the filter plate 84 move closer to each other. Due to the compression of space, the dust and mud are squeezed, which improves the separation effect of water and dust. The separated water will flow through the activated carbon plate 88 to the bottom of the dust collection bucket 14, and then be sucked back into the water tank 13 through the circulating water pipe 15. This solves the problem of the difficulty in separating mud and water. At the same time, water resources are saved through water circulation, and the water utilization rate is improved.

[0025] The anti-wall-hanging device 9 includes a hinge rod 91, a cleaning rod 92, a squeezing column 93, a rotating shaft 94, a rotating groove 95, a connecting sleeve 96, a striking rod 97, a return spring 98, and a filter plate 99. One end of the hinge rod 91 is hinged to the top outer wall of the filter plate 84, and the cleaning rod 92 is hinged to the other end of the hinge rod 91. The filter plate 99 is fixedly connected to the inner wall of the dust collection bin 14, and the cleaning rod 92 is slidably connected to the bottom outer wall of the filter plate 99. The squeezing column 93 is fixedly connected to the outer wall of the cleaning rod 92, and the connecting sleeve 96 is fixedly connected to the inner wall of the dust collection bin 14. The rotating shaft 94 is rotatably connected to the inner wall of the connecting sleeve 96. The rotating groove 95 is opened on the outer wall of the rotating shaft 94, and the squeezing column 93 is slidably connected to the inner wall of the rotating groove 95. A striking hole is opened on the outer wall of the rotating shaft 94, and one end of the return spring 98 is fixedly connected to the inner wall of the striking hole. The striking rod 97 is fixedly connected to the other end of the return spring 98.

[0026] When the filter plate 84 moves downward, it will pull the hinge rod 91 downward as well, thereby causing the cleaning rod 92 to move to both sides on the air filter plate 99 to complete the cleaning effect. This solves the problem that dust becomes more adhesive due to contact with water mist and sticks to the bottom of the air filter plate 99, thus reducing the dust collection efficiency. At the same time, when the cleaning rod 92 moves to both sides, it will drive the extrusion column 93 to slide in the rotating groove 95, thereby causing the rotating shaft 94 to be extruded and rotated in the connecting sleeve 96. When the rotating shaft 94 rotates, it will drive the striking rod 97 to rotate, thereby causing the striking rod 97 to strike the outer wall of the air filter plate 99. Furthermore, by setting a reset spring 98, the striking rod 97 is prevented from getting stuck, thus solving the problem of dust and mud accumulation in the corners around the air filter plate 99 that cannot be cleaned by the cleaning rod 92.

[0027] In this example, when vacuuming is required, the Z-shaped rod 716 reciprocates towards the vacuum bin 14, striking the atomizer 79. Simultaneously, the movement of the Z-shaped rod 716 causes the L-shaped rod 81 to move towards the vacuum bin 14, which in turn causes the pressure rod 82 to press against the pressure block 83. When the pressure block 83 is pressed, it causes the filter plate 84 to move downwards, thus pressing the pressure spring 85 and moving it towards the arc-shaped plate 86. When the Z-shaped rod 716 returns to its original position, it causes the pressure rod 82 to move away from the pressure block 83. The pressure on the pressure block 83 is released, the pressure spring 85 moves the filter plate 84 forwards... The filter plate 84 is reciprocated up and down by the reciprocating impact of the Z-shaped rod 716, which creates a vibration effect and improves the filtration efficiency of the filter plate 84. At the same time, when the L-shaped rod 81 moves towards the dust collection bin 14, it will drive the upper pressure rod 810 to move towards the dust collection bin 14 as well. This causes the upper pressure rod 810 to squeeze the upper pressure inclined block 89. The upper pressure inclined block 89 is squeezed, which drives the activated carbon plate 88 to move upward and compress the upper pressure spring 87. The upward movement of the activated carbon plate 88 and the downward movement of the filter plate 84 are synchronized, thereby compressing the space and squeezing the dust and sludge, thus improving the decomposition efficiency of the dust and sludge. When the filter plate 84 moves downward, it will pull the hinge rod 91 downward as well, causing the hinge rod 91 to pull the cleaning rod 92 to slide on the outer wall of the filter plate 99. When the filter plate 84 returns to its original position, the cleaning rod 92 will be squeezed by the hinge rod 91 and slide again. At the same time, when the cleaning rod 92 moves to both sides, it will drive the squeezing column 93 to slide in the rotating groove 95, causing the rotating shaft 94 to be squeezed by the rotating groove 95 and rotate in the connecting sleeve 96. When the rotating shaft 94 rotates, it will drive the striking rod 97 to rotate together. When the striking rod 97 rotates, it will strike the filter plate 99. By setting a return spring 98 and a striking hole, the striking rod 97 is prevented from getting stuck when striking the filter plate 99.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
