Description

Technical Field

[0001] The invention belongs to the technical field of dust removal devices, in particular to a dust removal device for building demolition. Background Art

[0002] When a building is demolished, a large amount of dust will appear, which will have a great impact on the environment and reduce visibility. Therefore, a dust removal device for building demolition will be used to control the dust and reduce the pollution of dust to the environment. Currently, the most commonly used is the fog cannon, which uses a water pump and a fan to produce a large amount of water mist, and uses the water mist to reduce dust in the building demolition area.

[0003] A patent with publication number CN221950857U discloses a dust removal device for a building demolition site. The patent provides a support shell to protect the rotating component, and the rotating component facilitates the nozzle to rotate, thereby increasing the dust removal area, improving the practicality of the device, and achieving better dust removal effect and higher dust removal efficiency. A cleaning component is provided at the nozzle outlet to facilitate cleaning of the inner wall of the nozzle, thereby avoiding excessive dust sticking to the inner wall of the nozzle, causing blockage and affecting the dust removal efficiency. A slide groove is provided for use with a slider to make the support rod more stable in rotation and achieve better cleaning effect. The device is simple to operate, easy to use, and saves time and effort.

[0004] There are still some problems in the actual application of the above scheme. Usually, a dust removal vehicle is used as a carrier to carry the fog cannon for movement. At the same time, a large water tank is required, and then a water pump and a fan are used together to generate a large amount of water mist to control the dust. However, when buildings are demolished, a large amount of dust will be generated, and the dust will carry fine gravel that will spread around. If the spray holes of the fog cannon for spraying water mist are not cleaned in real time, the dust will gather at the spray holes for a long time and cause blockage of several spray holes, thereby reducing the amount of water sprayed from the spray holes and affecting the suppression coverage of the fog cannon on the dust.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1 like Figures 1 to 10As shown, a building demolition dust removal device described in an embodiment of the present invention comprises a dust removal vehicle 1 and a front wheel 2 and a rear wheel 3 rotating at the lower end of the dust removal vehicle 1, a support frame 13 is installed on one side of the upper end surface of the dust removal vehicle 1, a blower 10 is rotatably connected to the inner cavity of the support frame 13, and the air outlet of the blower 10 is arranged in a cone shape for increasing the blowing air pressure, an annular pipe frame 12 is installed at the air outlet of the blower 10, and water spray holes are evenly opened on the inner wall of the annular pipe frame 12, a cleaning rod 31 is rotatably connected to the inner cavity of the annular pipe frame 12 for cleaning the inner wall of the annular pipe frame 12, a hose 11 is fixedly connected to the upper end of the annular pipe frame 12 for conveying clean water into the annular pipe frame 12 for spraying, and a quantitative water supply component 9 is installed on one side of the upper end surface of the dust removal vehicle 1; The quantitative water supply component 9 includes two L-shaped water pumping pipes 91 installed on one side of the upper end surface of the dust removal vehicle 1. Water supply ports 97 are provided at both ends of the L-shaped water pumping pipes 91. A one-way valve is provided in the inner cavity of the water supply port 97. The inner cavity of the water supply port 97 is fixedly connected to a diversion pipe 93. One end of the diversion pipe 93 is fixedly connected to the hose 11. The inner cavity diameter of the hose 11 is smaller than the inner cavity diameter of the diversion pipe 93, which is used to increase the water pressure of the water supply and improve the uniformity of the water mist.

[0023] Specifically, in the prior art, a dust removal vehicle is usually pushed to the building to be demolished, and the dust removal vehicle is moved to the downwind port, so that the wind can be used to carry the dust to reduce the range of the dust. Then, when the building is demolished, the dust will move to the dust removal vehicle with the wind, and at this time, the dust can be sprayed with a mist cannon, which can better cover the dust and achieve dust reduction. However, this will also cause the uncovered dust to float downwind to the dust reduction vehicle and the mist cannon. If the spray holes of the mist cannon for spraying water mist are not cleaned in real time, the dust will gather at the spray holes for a long time, causing blockage of several spray holes, reducing the amount of water sprayed from the spray holes, thereby affecting the suppression and coverage of the dust by the mist cannon and affecting the dust removal effect of the dust; The present invention drives the dust removal vehicle 1 to move by the front wheels 2 and the rear wheels 3, and at the same time, the hair dryer 10 rotates in the inner cavity of the support frame 13, thereby adjusting the blowing angle of the hair dryer 10, and then driving the L-shaped water pumping pipe 91 to pump clean water into the L-shaped water pumping pipe 91, and making the clean water in the inner cavity of the L-shaped water pumping pipe 91 squeeze the one-way valve to open the water supply port 97, and at the same time discharge it into the inner cavity of the diverter pipe 93, and then discharge it into the inner cavity of the hose 11, and the inner cavity diameter of the hose 11 is smaller than the inner cavity diameter of the diverter pipe 93, so that the clean water is squeezed in the diverter pipe 93, thereby ensuring that the water pressure of the clean water entering the inner cavity of the hose 11 increases, and then the clean water enters the inner cavity of the annular pipe frame 12 through the hose 11, and at the same time is sprayed out through the spray hole, and the air outlet of the hair dryer 10 is set in a cone shape, so as to blow During the operation of the hair dryer 10, the air will shrink as the inner cavity of the hair dryer 10 changes from large to small, thereby increasing the air flow rate and air pressure. After the air is discharged through the air outlet of the hair dryer 10, it will blow the water mist sprayed from the annular pipe rack 12 to diffuse, thereby covering and removing the dust generated by the demolition of the building. During the operation of the hair dryer 10, the cleaning rod 31 will also be driven to rotate, and a brush is evenly arranged at one end of the cleaning rod 31. During the rotation of the cleaning rod 31, the spray hole of the annular pipe rack 12 can be brushed and cleaned, thereby avoiding excessive dust after the demolition of the building, and the sprayed water mist is difficult to cover the dust, resulting in a small amount of dust adhering to the spray hole of the annular pipe rack 12, and long-term accumulation leads to blockage, thereby solving the above problem.

[0024] like Figures 6 to 9 As shown, a transmission column 21 is fixed between the rear wheels 3, a transmission bevel gear 22 is fixed to the outside of the transmission column 21, the transmission bevel gear 22 is meshingly connected to the driven bevel gear 23, a cylinder 24 is fixed to the inside of the driven bevel gear 23, and the cylinder 24 is rotatably connected to the dust removal vehicle 1, one end of the cylinder 24 passes through the dust removal vehicle 1 and is fixed to a disc 25, and a fixed round block 26 is fixed to one side of the upper end surface of the disc 25, which is used to drive the L-shaped water pumping pipe 91 to pump water.

[0025] like Figures 6 to 9 As shown, a circular fixing frame 94 is arranged between the L-shaped water pumping pipe 91, and the fixed circular block 26 is slidably connected to the circular fixing frame 94, sliding columns 95 are fixedly connected at both ends of the circular fixing frame 94, a piston 96 is fixedly connected at one end of the sliding column 95, and the piston 96 is slidably connected to the inner cavity of the L-shaped water pumping pipe 91, a water tank 15 is installed on the upper end surface of the dust removal vehicle 1, a water pumping port 92 is opened at one end of the L-shaped water pumping pipe 91, and the water pumping port 92 is fixedly connected to the water tank 15, and a one-way valve is arranged in the inner cavity of the water pumping port 92.

[0026] Specifically, when the rear wheel 3 moves, the transmission column 21 will be driven to rotate, and the transmission column 21 will drive the transmission bevel gear 22 to rotate, and the meshing transmission driven bevel gear 23 will rotate, and then drive the cylinder 24 to rotate. During the rotation of the cylinder 24, the disc 25 will be driven to rotate, and the disc 25 will drive the fixed round block 26 to rotate, and the fixed round block 26 slides in the inner cavity of the circular fixing frame 94. In the process of the disc 25 driving the fixed round block 26 to rotate, the circular fixing frame 94 will be cyclically driven to push, and the circular fixing frame 94 will cyclically push and pull the sliding column 95 to slide in the inner cavity of the L-shaped water pumping pipe 91, and the sliding column 95 will drive the piston 96 to slide in the inner cavity of the L-shaped water pumping pipe 91 during the sliding process. When the piston 96 pulls the inner cavity of the L-shaped water pumping pipe 91 to form a negative pressure, the one-way valve in the inner cavity of the water pumping port 92 will be opened, and the clean water in the inner cavity of the water tank 15 will be drawn into the L-shaped water pumping pipe 91. The clean water in the L-shaped water pumping pipe 91 is squeezed by the piston 96, and then the clean water squeezes the one-way valve in the inner cavity of the water supply port 97 into the shunt pipe 93. At the same time, the clean water is discharged into the hose 11 through the shunt pipe 93 and flows into the inner cavity of the annular pipe rack 12. The inner cavity diameter of the hose 11 is smaller than the inner cavity diameter of the shunt pipe 93, thereby ensuring that the water pressure of the clean water entering the inner cavity of the hose 11 increases. After the clean water enters the inner cavity of the annular pipe rack 12 through the hose 11, it can use the increased water pressure to form water mist and spray it out quickly through the water spray hole, thereby solving the problem that the existing building demolition dust removal device usually uses a water pump to pressurize and transport clean water, and then cooperates with the fog cannon fan to spray water mist for dust removal. However, the water pump cannot control the delivery amount of clean water when transporting clean water, which is easy to consume clean water too quickly, and it is difficult to ensure the stability and consistency of the fog cannon spray. In addition, the water pump has a complex structure and is easily damaged by dust entering the inside.

[0027] like Figure 4 , Figure 5 and Fig. 9 As shown, a U-shaped fixing block 17 is fixedly connected to the bottom of the inner cavity of the support frame 13, an electric push rod 16 is rotatably connected to the inner cavity of the U-shaped fixing block 17, and an H-shaped connecting block 18 is rotatably connected to the piston rod end of the electric push rod 16, and the H-shaped connecting block 18 is rotatably connected to the hair dryer 10.

[0028] like Figure 5 , Fig. 9 and Fig.10 As shown, the inner cavity of the hair dryer 10 is fixedly connected to a fixing frame 27, a brushless motor 28 is arranged inside the fixing frame 27, an impeller 29 is fixedly connected to the output shaft end of the brushless motor 28, one end of the impeller 29 is fixedly connected to a guide rod 30, the outer part of the guide rod 30 is provided with raised blades in a threaded shape for guiding the flow of air, and one end of the guide rod 30 is fixedly connected to a cleaning rod 31.

[0029] Specifically, when the dust is sprayed and removed, the electric push rod 16 is used to drive the H-shaped connecting block 18 to move upward, and the H-shaped connecting block 18 pushes the hair dryer 10 to move upward to adjust the angle, and then the brushless motor 28 is started to drive the impeller 29 to rotate, and the impeller 29 drives the guide rod 30 to rotate. Since the guide rod 30 is provided with raised blades on the outside in a threaded shape, when the air is blown through the hair dryer 10, the air will flow in a threaded shape along the raised blades on the outside of the guide rod 30, and the threaded raised blades will exert a certain pressure on the air in the process of guiding the air flow, thereby increasing the distance the air is ejected from the hair dryer 10, and at the same time, the water mist sprayed by the annular pipe rack 12 is blown out to increase the coverage of the spray, so that the equipment has better performance in spraying, dust removal, etc.

[0030] Embodiment 2 like Figure 1 , Figure 3 and Fig. 9 As shown, a cleaning assembly 4 is installed on the lower end surface of the dust removal vehicle 1, and the cleaning assembly 4 includes a semicircular ash shovel 41 fixedly connected to the lower end surface of the dust removal vehicle 1, the inner cavity of the semicircular ash shovel 41 is rotatably connected to a rotating column 49, the outside of the rotating column 49 is fixedly connected to a rotating cylinder 42, the outside of the rotating column 49 is fixedly connected to a plurality of fixed sliding columns 44, and one end of the plurality of fixed sliding columns 44 is slidably connected to a T-shaped slide plate 43, and the T-shaped slide plate 43 is slidably connected to the rotating cylinder 42.

[0031] like Figure 1 , Figure 3 and Fig. 9 As shown, the fixed sliding column 44 is fixedly connected to a fixed plate 46 on the outside, a spring 45 is fixedly connected to one end surface of the fixed plate 46, and one end of the spring 45 is fixedly connected to the T-shaped slide plate 43. Brushes are evenly arranged at one end of the T-shaped slide plate 43 for cleaning dust from entering the semicircular ash shovel 41.

[0032] like Figure 3 , Figure 8 and Fig. 9 As shown, an ash inlet 48 is provided on the upper wall of the inner cavity of the semicircular ash shovel 41, and a one-way cover plate 47 is provided in the inner cavity of the ash inlet 48. The upper end surface of the dust removal vehicle 1 is fixedly connected to a dust collecting box 14, and a one-way cover plate 47 is provided in the inner cavity of the dust collecting box 14. One end of the hair dryer 10 is fixedly connected to an exhaust duct 19, and the exhaust duct 19 is connected to the inner cavity of the dust collecting box 14, and a filter cloth is provided in the inner cavity of the exhaust duct 19 to filter dust and prevent it from escaping.

[0033] Specifically, when the dust removal vehicle 1 is moving to remove dust, the front wheel 2 will drive the chain 6 to rotate, and the chain 6 will drive the first sprocket 7 to rotate, thereby driving the rotating column 49 to rotate, and the rotating column 49 will drive the rotating cylinder 42 to rotate. During the rotation process, the rotating column 49 will also drive the fixed sliding column 44 to rotate, and at the same time drive the T-shaped slide plate 43 to rotate, and a brush is evenly arranged at one end of the T-shaped slide plate 43, and during the rotation process of the T-shaped slide plate 43, the brush will be used to sweep the dust into the inner cavity of the semicircular ash shovel 41, and after the T-shaped slide plate 43 cleans the dust and enters the inner cavity of the semicircular ash shovel 41, the T-shaped slide plate 43 will cooperate with the semicircular ash shovel 41 to slide on the outside of the fixed sliding column 44, and at the same time, the spring 45 will be used to bounce the T-shaped The slide plate 43 abuts against the semicircular ash shovel 41, thereby ensuring that the T-shaped slide plate 43 cooperates with the inner wall of the semicircular ash shovel 41 to drive the dust to rotate and move in the inner cavity of the semicircular ash shovel 41. When the dust moves to the ash inlet 48, the air in the inner cavity of the dust box 14 is extracted by utilizing the hair dryer 10 in cooperation with the exhaust duct 19, and then the one-way cover plate 47 in the inner cavity of the dust box 14 and the one-way cover plate 47 in the inner cavity of the ash inlet 48 are opened, so that the dust is drawn into the dust box 14 for collection, thereby solving the problem that after the existing building demolition dust removal device sprays the dust generated by the building demolition during the house decoration process, it is inconvenient to clean and collect the dust on the floor, resulting in dust after the dust has been dried for a long time and still dust will appear.

[0034] like Figure 3 , Figure 8 and Fig. 9 As shown, one side of the semicircular ash shovel 41 is fixedly connected to a gravel recovery box 5, a receiving groove 32 is provided in the inner cavity of the gravel recovery box 5, a micro spring 33 is fixedly connected to the bottom of the inner cavity of the receiving groove 32, a semicircular slide plate 34 is fixedly connected to one end of the micro spring 33, a screw rod 35 is rotatably connected to the inner cavity of the gravel recovery box 5, the outer surface of the screw rod 35 is threadedly connected to the scraper 20, and the scraper 20 is slidably connected to the inner cavity of the gravel recovery box 5.

[0035] like Figure 3 , Figure 8 and Fig. 9 As shown, one end of the rotating column 49 passes through the semicircular ash shovel 41 and is fixedly connected to the first sprocket 7, and the first sprocket 7 is externally meshed with a chain 6 for transmission, and one end of the screw rod 35 passes through the gravel recovery box 5 and is fixedly connected to the second sprocket 8, and the second sprocket 8 is meshed with the chain 6 for transmission, and one end of the chain 6 is meshed with the front wheel 2 for transmission.

[0036] Specifically, after the dust is extracted into the dust box 14 for storage by using the hair dryer 10 in cooperation with the exhaust duct 19, the T-shaped slide plate 43 in cooperation with the rotating cylinder 42 will drive the gravel to move to the gravel recovery box 5, and at the same time, the T-shaped slide plate 43 abuts against the semicircular slide plate 34 to squeeze the micro spring 33 to slide into the inner cavity of the storage groove 32, thereby opening the gravel recovery box 5, and then the gravel between the T-shaped slide plates 43 will slide into the inner cavity of the gravel recovery box 5, and during the rotation of the front wheel 2, the transmission chain 6 will rotate, and drive the second sprocket 8 to rotate , and then drives the screw rod 35 to rotate, and at the same time, the screw rod 35 threaded transmission scraper 20 slides in the inner cavity of the gravel recovery box 5, and then pushes the gravel recovered in the inner cavity of the gravel recovery box 5 to one side, so as to facilitate the collection and treatment of the gravel, and solves the problem that when the existing building demolition dust removal device is cleaning and collecting dust, due to the presence of gravel in the dust and the heavy gravel, it is difficult to use the vacuum cleaner to clean up the gravel. In severe cases, the gravel enters the vacuum cleaner and easily causes damage to the vacuum cleaner.

[0037] Working principle: the dust removal vehicle 1 is driven to move by the front wheels 2 and the rear wheels 3, and the hair dryer 10 rotates in the inner cavity of the support frame 13, thereby adjusting the blowing angle of the hair dryer 10, and then driving the L-shaped water pumping pipe 91 to pump clean water into the L-shaped water pumping pipe 91, and make the clean water in the inner cavity of the L-shaped water pumping pipe 91 squeeze the one-way valve to open the water supply port 97, and at the same time discharge it into the inner cavity of the diverter pipe 93, and then discharge it into the inner cavity of the hose 11, and the inner cavity diameter of the hose 11 is smaller than the inner cavity diameter of the diverter pipe 93, so that the clean water is squeezed in the diverter pipe 93, thereby ensuring that the water pressure of the clean water entering the inner cavity of the hose 11 increases, and then the clean water enters the inner cavity of the annular pipe frame 12 through the hose 11, and is sprayed out through the spray hole, and the air outlet of the hair dryer 10 is set in a cone shape. Furthermore, during the operation of the hair dryer 10, the air will decrease as the inner cavity of the hair dryer 10 changes from large to small, thereby increasing the air flow rate and air pressure, and then after the air is discharged through the air outlet of the hair dryer 10, it will blow the water mist sprayed from the annular pipe rack 12 to diffuse, thereby covering and removing the dust generated by the demolition of the building. During the operation of the hair dryer 10, the cleaning rod 31 will also be driven to rotate, and a brush is evenly arranged at one end of the cleaning rod 31. During the rotation of the cleaning rod 31, the spray hole of the annular pipe rack 12 can be brushed and cleaned, thereby avoiding the situation where the dust is too large after the demolition of the building, and the sprayed water mist is difficult to cover the dust, resulting in a small amount of dust adhering to the spray hole of the annular pipe rack 12, and accumulating for a long time to cause blockage; When the dust removal vehicle 1 is moving to remove dust, the chain 6 is driven to rotate through the front wheel 2, and the chain 6 drives the first sprocket 7 to rotate, which in turn drives the rotating column 49 to rotate, and the rotating column 49 drives the rotating cylinder 42 to rotate. During the rotation process, the rotating column 49 also drives the fixed sliding column 44 to rotate, and drives the T-shaped slide plate 43 to rotate at the same time. Brushes are evenly arranged at one end of the T-shaped slide plate 43, and during the rotation process of the T-shaped slide plate 43, the brushes are used to sweep the dust into the inner cavity of the semicircular ash shovel 41. After the clean dust from the T-shaped slide plate 43 enters the inner cavity of the semicircular ash shovel 41, the T-shaped The slide plate 43 will cooperate with the semicircular ash shovel 41 to slide outside the fixed slide column 44, and at the same time, the spring 45 will be used to bounce the T-shaped slide plate 43 to abut against the semicircular ash shovel 41, thereby ensuring that the T-shaped slide plate 43 cooperates with the inner wall of the semicircular ash shovel 41 to drive the dust to rotate and move in the inner cavity of the semicircular ash shovel 41. When the dust moves to the ash inlet 48, the air in the inner cavity of the dust box 14 is extracted by using the blower 10 in cooperation with the exhaust duct 19, and then the one-way cover plate 47 in the inner cavity of the dust box 14 and the one-way cover plate 47 in the inner cavity of the ash inlet 48 are opened, so that the dust is drawn into the dust box 14 for collection; After the dust is extracted into the dust collecting box 14 for storage by using the hair dryer 10 in cooperation with the exhaust duct 19, the T-shaped slide plate 43 in cooperation with the rotating cylinder 42 will drive the gravel to move to the gravel recovery box 5, and at the same time, the T-shaped slide plate 43 abuts against the semicircular slide plate 34 to squeeze the micro spring 33 into the inner cavity of the storage groove 32, thereby opening the gravel recovery box 5, and then the gravel between the T-shaped slide plates 43 will slide into the inner cavity of the gravel recovery box 5, and during the rotation of the front wheel 2, the transmission chain 6 will rotate, and drive the second sprocket 8 to rotate, and then drive the screw rod 35 to rotate, and at the same time, the screw rod 35 threaded drive scraper 20 slides in the inner cavity of the gravel recovery box 5, and then the gravel recovered in the inner cavity of the gravel recovery box 5 is pushed to one side, thereby facilitating the collection and processing of the gravel.
