Description

Technical Field

[0001] The present invention belongs to the technical field of housing construction, and particularly relates to a dust removal device for housing construction. Background Art

[0002] With the development of society and economy, people's living standards have been continuously improved. Nowadays, the urbanization level of society is increasing, and cities are constantly expanding. During the expansion of cities, many housing buildings need to be built. When building housing buildings, a large amount of dust is often generated. These dusts float in the air. Construction workers will inhale a lot of floating dust in such an environment. Even wearing masks, they will inhale a considerable amount of floating dust. Prolonged inhalation of floating dust will cause great damage to the lungs of construction workers and even may cause cancer. Moreover, the floating dust will also affect the work efficiency of construction workers. Therefore, it is very necessary to take certain dust removal measures at the construction site.

[0003] However, for the existing dust removal devices for housing construction, one is to adsorb dust into the dust removal box through a dust collector, and then pump the water in the dust removal box through a water pump and spray the dust in the dust removal box through a nozzle, so that the dust is mixed with water. However, when pumping and circulating the mixed water to spray the dust through the water pump, when the water pump works for a long time, due to too much dust mixed in the water, the water pipes and nozzles in the water pump will be blocked, affecting the normal operation of the dust removal device. Generally, the dust removal devices in the prior art install atomizing nozzles on the water pipes and remove dust by spraying mist. The other is to fix the water pipe on the top of the wall and spray and remove dust through the atomizing nozzle, but it is impossible to adjust the appropriate water spray volume. Too much water will cause the house to be too humid, and too little water cannot achieve the ideal dust removal effect. Summary of the Invention

[0004] Aiming at the problems raised in the above background art, the purpose of the present invention is to provide a dust removal device for housing construction.

[0005] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

A discharge pump is installed at the output end of the water outlet pipe. A drain pipe is also connected to the input end of the water outlet pipe. A second control valve is installed inside the drain pipe. The top of the drain pipe penetrates through the handcart frame and the water tank and is installed on one side of the bottom of the water tank. With such a structural design, after cleaning, the first control valve can be opened first to discharge the dust in the sedimentation hopper, and then the second control valve can be opened to discharge the water in the water tank, thereby flushing the water outlet pipe to prevent dust from accumulating in the water outlet pipe.

[0010] Further defined, a double-layer seal seat is installed at the penetration of the handcart frame and the water tank for the slag discharging pipe and the drain pipe. The slag discharging pipe and the drain pipe are arranged inside the double-layer seal seat. Such a structural design has a sealing effect and prevents water leakage.

[0011] Further defined, the output end of the water pump is connected to a pressure pump, and the output end of the pressure pump is connected to the input end of the conveying pipe. Such a structural design improves the water use effect of the atomizing nozzle and the spraying assembly.

[0012] Further defined, the spraying assembly includes a folding pipe connected to the output end of the shunt pipe. The output end of the folding pipe is connected to an atomizer. An inner liner is sleeved outside the atomizer. A number of uniformly arranged strip-shaped grooves are provided on the outer circumference of the inner liner. An adjusting sleeve is rotatably installed outside the inner liner. Spraying grooves matching the strip-shaped grooves are provided on the adjusting sleeve.

A water level observation board is provided outside the water tank corresponding to the floating ball. A water replenishing pipe is also installed on one side of the water tank. Such a structural design is convenient for checking the internal water level so as to add water in time.

[0015] Further defined, a dustproof net is installed at the top of the exhaust groove. Such a structural design can prevent dust from entering the dust removal cover through the exhaust groove.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. By providing a partition board, a flow guide board, and an atomizing nozzle between the two flow guide boards, the present invention can increase the flow path of gas in the dust removal hood and achieve uniform atomized water spraying through the atomizing nozzle, effectively enabling the dust to be completely wetted and condensed for sedimentation, greatly improving the dust sedimentation effect.

[0018] 2. By providing a filtering component and a slag discharging component, the present invention can separate dust and water, preventing the dust from settling in the water and being pumped away together with the water. During cleaning, the water with dust can be discharged first, and then relatively clean water can be used for flushing, effectively preventing the blockage of pipelines.

[0019] 3. By providing a spraying component and a lifting component, the present invention can adjust the height of the spraying component during use, making the spraying range of the spraying component wider. At the same time, the spraying component can also be adjusted to control the appropriate water spraying amount, preventing the house from being overly humid due to too much sprayed water and ensuring that the ideal dust removal effect cannot be achieved due to too little water.

Detailed implementation manner

[0029] In order to enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be further described below in conjunction with the drawings and embodiments.

[0030] Embodiment 1, as Figure 1 and Figure 2 shown, a dust removal device for building construction, self-locking universal wheels 2 are installed on the four sides of the bottom of the hand-push frame 1, a water tank 3 is installed on the surface of the hand-push frame 1, a partition board 4 is installed on the top of the water tank 3, a leakage trough 5 is provided in the center of the partition board 4, a filtering component 6 is installed on the lower side of the partition board 4 in the leakage trough 5, the bottom of the filtering component 6 is connected with a slag discharging component 7, the slag discharging component 7 is arranged at the bottom of the hand-push frame 1, a diversion plate 8 is installed at the center of the top of the partition board 4 in the leakage trough 5, a dust removal cover 9 is installed on the top of the water tank 3, a dust suction device 10 is installed on the right side inside the dust removal cover 9, baffles 11 are installed on both sides of the top of the dust removal cover 9 corresponding to the leakage trough 5, the diversion plate 8 and the baffles 11 form a meandering channel, a shunt plate 12 is installed between the two baffles 11, a plurality of atomizing nozzles 13 are installed at the output end of the bottom of the shunt plate 12, a wall panel 14 is installed on the left side inside the dust removal cover 9, a conveying pipe 15 is installed between the wall panel 14 and the dust removal cover 9, the bottom input end of the conveying pipe 15 is arranged in the water tank 3 and is connected with a water pump 16, one side of the top of the conveying pipe 15 is connected with a shunt pipe 17, the output end of the shunt pipe 17 is connected with the shunt plate 12, the top output end of the shunt pipe 17 is connected with a spraying component 18, a lifting component 19 is installed on the outside of the dust removal cover 9, the power output end of the lifting component 19 is connected with the spraying component 18, and exhaust grooves 20 are provided on both sides of the dust removal cover 9 where the shunt pipe 17 is located.

[0031] In this embodiment, during use, first, the operator pushes the handcart frame 1. After the handcart frame 1 drives the self-locking universal wheels 2 to move to a suitable position, the self-locking universal wheels 2 are self-locked and fixed. Then, the dust collection device 10 is started, and the air carrying dust from the outside is pumped into the dust removal cover 9. When the gas enters the dust removal cover 9, since the diversion plate 8 and the baffle 11 form a circuitous channel, the flow path of the gas in the dust removal cover 9 is increased. At the same time, the water pump 16 is started. The water pump 16 inputs the water in the water tank 3 into the delivery pipe 15, and is input into the shunt pipe 17 and the spray assembly 18 by the delivery pipe 15. When the water passes through the shunt pipe 17 and is shunted by the shunt plate 12 and then sprayed out from the atomizing nozzles 13, the water mist is mixed with the dust in the air, thereby increasing the weight of the dust, causing the dust to fall through the leakage trough 5 into the filtering assembly 6. Since the filtering assembly 6 is arranged in the water tank 3, after the dust falls into the filtering assembly 6, separation will occur again. The water will flow out from the filtering assembly 6 for reuse, while the dust stays in the filtering assembly 6. The air after dust removal is discharged from the exhaust groove 20. During the process of dust collection and removal, the lifting assembly 19 can also be controlled to drive the spray assembly 18 to adjust the height, so that after the height of the spray assembly 18 is adjusted, the spraying range can be wider. The water input into the delivery pipe 15, a part of it enters the shunt pipe 17 for spray dust removal, and the other part of the water enters the spray assembly 18 and is sprayed out by the spray assembly 18 for spray dust reduction work, achieving the effect of double dust removal. And the water output of the spray assembly 18 can also be adjusted to make it reach a suitable water spray amount for spray dust reduction use.

A number of filter holes 22 are provided on the circumference of the return frame 21, and filter meshes 23 are installed in the filter holes 22. A sedimentation hopper 24 is installed at the bottom of the return frame 21. The sedimentation hopper 24 is arranged in a flared structure with a large top and a small bottom, and the bottom of the sedimentation hopper 24 is connected to the slag discharge assembly 7.

[0033] In this embodiment, during use, the sewage mixed with dust falls from the leakage trough 5 into the return frame 21. After contacting the water in the return frame 21, separation occurs. Through the filter meshes 23 in the filter holes 22, the dust can stay in the return frame 21 and finally settle in the sedimentation hopper 24. The filtered water can be communicated with the water tank 3 through the filter holes 22, so that the water can enter the water tank 3 through the filter meshes 23 for repeated use. When the use is finally completed, the slag discharge assembly 7 can be used to discharge the dust and residual water in the sedimentation hopper 24 together to achieve the cleaning effect.
