Description

Technical Field

[0001] This invention belongs to the field of dust removal equipment technology, and more specifically, relates to a dust removal device for building construction. Background Technology

[0002] When workers are working inside a building, they damage the walls, and a lot of dust is often generated when chiseling walls. This dust floats in the air, and construction workers will inhale a lot of dust while working in this environment. Therefore, certain dust control measures must be taken at the construction site.

[0003] In current technology, when workers are chiseling walls, they generally only wear dust masks and other dust-protective gear. However, the dust generated during chiseling still fills the entire building, significantly impacting the environment. Furthermore, some workers may remove their dust masks because they feel that wearing them hinders breathing and makes their work inconvenient. When workers remove their dust masks, they inhale the dust, which can cause harm. Summary of the Invention

[0004] The purpose of this invention is to provide a dust removal device for building construction, so as to reduce dust during indoor construction.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A dust removal device for construction includes an installation platform, a dust collection box, a dust collection mechanism, a spraying mechanism, and a sewage discharge mechanism.

The inner diameter of the side plates is the same as that of the bottom plate, and the outer diameter of the side plates is larger than that of the bottom plate. The outer diameter of the side plates is the same as that of the spray trough. When the spray ring is inserted into the spray trough, the bottom surfaces of the two side plates, the bottom plate, and the spray trough form the supply cavity. The water supply assembly includes a water pump and a water pipe. The water pump is located in the water storage cavity. One end of the water pipe is connected to the output end of the water pump, and the other end of the water pipe is connected to the connection hole.

[0009] In one possible implementation, the sewage discharge mechanism includes a vertical cylinder, a horizontal cylinder, a spiral conveyor rod, a drive motor, a filter assembly, and a sewage discharge box. The vertical cylinder is vertically arranged, with a portion inserted into the dust collection box. The top end of the vertical cylinder extends above the dust collection box, and the bottom end of the vertical cylinder is located within the sewage storage chamber. The horizontal cylinder is connected to the top end of the vertical cylinder and is in communication with the vertical cylinder.

The spiral conveyor rod is rotatably disposed within the vertical cylinder. The drive motor is located at the top of the vertical cylinder, and the top end of the spiral conveyor rod is connected to the power output end of the drive motor. The filter assembly is connected to the horizontal cylinder. The sewage discharge box is located on one side of the dust collection box, with an opening at the top. The sewage outlet of the filter assembly is located above the sewage discharge box.

[0010] In one possible implementation, the drive assembly includes multiple connecting rods and a pivot cylinder. The vertical cylinder includes an upper cylinder at the top, a lower cylinder at the bottom, and a pivot cylinder rotatably disposed between the upper and lower cylinders. An insert block with a T-shaped cross-section is provided on the end face of the pivot cylinder. A first slot with a shape adapted to the insert block is provided on the bottom surface of the upper cylinder. The insert block at the top of the pivot cylinder is inserted into the first slot. A second slot with a shape adapted to the insert block is provided on the top surface of the lower cylinder. The insert block at the bottom of the pivot cylinder is inserted into the second slot. Multiple insertion holes are provided on the pivot cylinder, each corresponding to a connecting rod. The connecting rod passes through the corresponding insertion hole, with one end of the connecting rod connected to the spiral conveyor rod and the other end connected to the spray ring.

[0011] In one possible implementation, the filtration assembly includes a filter cylinder, a water storage cylinder, and a sealing device. The filter cylinder is made of a filter screen that allows water to pass through, and the filter cylinder is cylindrical. The top end of the filter cylinder is connected to the horizontal cylinder. The water storage cylinder is cylindrical, and both ends of the water storage cylinder are sealed. The top and bottom surfaces of the water storage cylinder are provided with insertion holes, the diameter of which is the same as the outer diameter of the filter cylinder. The height of the water storage cylinder is the same as the height of the filter cylinder. The filter cylinder is fixed in the insertion holes. The sealing device is rotatable and can seal or unseal the bottom end of the filter cylinder by rotating. A return water pipe is provided between the water storage cylinder and the water storage chamber.

[0012] In one possible implementation, the sealing device includes a sealing plate, a pressure sensor, a mounting plate, a drive unit, and a control component. The pressure sensor is mounted on the mounting plate, and the sealing plate is mounted on the sensing end of the pressure sensor. The mounting plate is connected to the drive unit, the pressure sensor is connected to the control component, and the control component is connected to the drive unit. The control component has a preset pressure value and a preset time value. In the initial state, the sealing plate covers the bottom end of the filter cartridge. When the pressure sensor detects the preset pressure value, the control component controls the drive unit to drive the mounting plate to rotate, releasing the sealing plate from the filter cartridge. When the time for releasing the sealing reaches the preset time value, the control component controls the drive unit to drive the mounting plate to rotate, causing the sealing plate to seal the bottom end of the filter cartridge.

[0013] In one possible implementation, the drive unit includes a pivot motor and a pivot rod. The pivot motor is located on the outer wall of the water storage cylinder, the top end of the pivot rod is connected to the pivot motor, and the other end of the pivot rod is connected to the mounting plate. The control component is located on the side wall of the water storage cylinder and is connected to the pivot motor. One end of the horizontal cylinder extending to the outside of the dust collector is bent downward to form a push tube, and the filter cylinder is connected to the push tube.

[0014] In one possible implementation, the bottom of the installation platform is provided with multiple casters that can be locked and unlocked.

[0015] The beneficial effects of the dust removal device for construction provided by this invention are as follows: Compared with the prior art, this invention, by setting up a dust collection box and a dust suction mechanism, draws in dust-laden air from the room into the dust collection box. Then, by setting up a spray mechanism, the air drawn into the dust collection box is sprayed with water mist, which adsorbs the dust in the air and causes it to settle and be stored in the sludge storage chamber. This effectively reduces the amount of dust in the air, preventing environmental damage and benefiting the health of workers. Furthermore, the inclusion of a sewage discharge mechanism facilitates the filtration and transportation of waste, and the filtered water can be recycled and reused, effectively conserving water resources.

In the description of this invention, "a plurality of" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0033] The dust removal device for building construction provided by the present invention will now be described.

[0034] Please refer to the following: Figure 1 and Figure 2 The dust removal device for construction includes an installation platform 1, a dust collection box 2, a dust collection mechanism, a spraying mechanism, and a sewage discharge mechanism. The dust collection box 2 is installed on the installation platform 1 and has a dust collection chamber 201, a water storage chamber 202, and a sewage storage chamber 203 inside. The dust collection mechanism is installed on the dust collection box 2 and can draw in outside air into the dust collection chamber 201. The spraying mechanism is rotatably installed in the dust collection chamber and can draw in clean water from the water storage chamber 202 and spray it onto the air drawn in by the dust collection mechanism. The washed-out dirt is stored in the sewage storage chamber 203. The sewage discharge mechanism is partially installed in the dust collection box and can transport and filter the dirt. The filtered water is introduced into the water storage chamber 202, and the filtered dirt is discharged.

[0035] The beneficial effects of the dust removal device for construction provided in this embodiment are as follows: Compared with the prior art, the dust removal device for construction provided in this embodiment, by setting up a dust collection box 2 and a dust suction mechanism, can draw in indoor air mixed with dust into the dust collection box 2. Then, by setting up a spray mechanism, the spray mechanism sprays the air drawn into the dust collection box 2, and the water mist adsorbs the dust in the air and makes it settle and be stored in the sludge storage chamber 203, thereby effectively reducing the dust in the air. On the one hand, it can prevent environmental damage, and on the other hand, it is beneficial to the health of workers. At the same time, since a sewage discharge mechanism is also set up, it is convenient to filter and transport the sewage, and the filtered water can be recycled and reused, effectively saving water resources.

[0036] Based on the above design concept, the dust collector 2 of the present invention is cylindrical, and a funnel-shaped guide plate 204 is provided inside the dust collector 2. The space above the guide plate 204 forms a dust collection chamber 201. A cylindrical partition plate 205 is provided on the inner bottom surface of the dust collector 2. The top of the partition plate 205 is connected to the bottom surface of the guide plate 204. The space enclosed by the side wall of the dust collector 2, the bottom surface of the dust collector 2, the partition plate 205 and the guide plate 204 forms a water storage chamber 202. The internal space of the partition plate 205 forms a sludge storage chamber 203. A drain hole 206 is provided on the guide plate 204. The diameter of the sludge storage chamber 203 is larger than the diameter of the drain hole 206.

[0037] During the spraying process, some of the dust adsorbed by the water mist will settle directly into the sludge storage chamber 203, while some will settle on the guide plate 204. Since the guide plate 204 is funnel-shaped, it can guide the mixture of dust and water settled on the guide plate 204 into the sludge storage chamber 203 for storage. Furthermore, by designing the water storage chamber 202 as a sealed cavity, it prevents contaminants from entering the water.

[0038] It is worth noting that a portion of the guide plate 204 extends into the partition plate 205. An air outlet pipe is provided below the guide plate 204. The air outlet pipe is inclined from the inside to the outside from low to high. One end of the air outlet pipe located in the dust collector 2 is located in the sludge storage chamber 203 and above the lowest end of the guide plate 204. In addition, a filter screen is provided at this end to prevent dirt from being carried out of the air outlet pipe by the air.

[0039] Combination Figure 2 and Figure 3 As shown, the spraying mechanism includes a spraying tank, a spraying ring 3, a water supply component, and a drive component. The spraying tank is annular and is located on the inner wall of the dust removal chamber 201. A connection hole is provided on the bottom surface of the spraying tank, which connects the spraying tank to the external space of the dust removal box 2.

[0040] The spray ring 3 is rotatably disposed in the spray tank. The two side walls of the spray tank abut against the two end faces of the spray ring 3 respectively. The side walls of the spray tank and the corresponding end faces of the spray ring 3 are sealed. A supply cavity is formed between the bottom surface of the spray tank and the spray ring 3.

[0041] The spray ring 3 is provided with multiple nozzles 302, each nozzle 302 is connected to the supply chamber 301; the drive component is located in the dust removal chamber 201, and the drive component can drive the spray ring 3 to rotate; one end of the water supply component is connected to the supply chamber, and the other end of the water supply component is connected to the connection hole, and the water supply component can supply water in the water storage chamber 202 to the supply chamber and spray it out from the nozzle.

[0042] The above configuration facilitates the rotation of the spray ring 3. Compared to using a pipeline for water supply, it effectively prevents the pipeline from moving with the spray ring 3 when it rotates. Prolonged movement can cause pipeline fatigue and aging. The configuration of this invention will improve the service life of the spray mechanism.

[0043] Specifically, in this embodiment, the spray ring 3 includes two side plates 303 and a bottom plate 304. Both the side plates 303 and the bottom plate 304 are annular. The inner diameter of the side plates 303 is the same as the inner diameter of the bottom plate 304, and the outer diameter of the side plates 303 is larger than the inner diameter of the bottom plate 304. The outer diameter of the side plates 303 is the same as the outer diameter of the spray tank. When the spray ring 3 is inserted into the spray tank, the two side plates 303, the bottom plate 304, and the bottom surface of the spray tank form a supply cavity. This arrangement of the spray ring 3 facilitates the formation of the supply cavity, thereby facilitating the supply of water to the spray ring 3. The water supply assembly includes a water pump 305 and a water pipe 306. The water pump 305 is located in the water storage chamber 202. One end of the water pipe 306 is connected to the output end of the water pump 305, and the other end of the water pipe 306 is connected to a connection hole.

[0044] Combination Figure 2 , Figure 4 and Figure 5 As shown, the sewage discharge mechanism includes a vertical cylinder 401, a horizontal cylinder 4, a screw conveyor 402, a drive motor 403, a filter assembly, and a sewage discharge box 404. The vertical cylinder 401 is vertically arranged, with a portion of it inserted into the dust collection box 2. The top of the vertical cylinder 401 extends above the dust collection box 2, and the bottom of the vertical cylinder 401 is located in the sewage storage chamber 203. The horizontal cylinder 4 is connected to the top of the vertical cylinder 401 and is in communication with the vertical cylinder 401. One end of the horizontal cylinder 4 extends to one side of the dust collection box 2. The spiral conveyor rod 402 is rotatably installed inside the vertical cylinder 401. The drive motor 403 is installed at the top of the vertical cylinder 401. The top end of the spiral conveyor rod 402 is connected to the power output end of the drive motor 403. The filter assembly is connected to the horizontal cylinder 4. The sewage discharge box 404 is installed on one side of the dust collection box 2. The top opening of the sewage discharge box 404 is provided. The sewage outlet of the filter assembly is located above the sewage discharge box 404.

[0045] The arrangement of the vertical cylinder 401, horizontal cylinder 4, spiral conveyor 402 and drive motor 403 allows the waste in the waste storage chamber 203 to enter the horizontal cylinder 4 along the vertical cylinder 401 when the drive motor 403 drives the spiral conveyor 402 to rotate, thus facilitating the transport of waste. The waste can be easily filtered through the facility's filter assembly, the filtered water can be recycled, and the filtered waste can be discharged.

[0046] like Figure 3 and Figure 4As shown, the drive assembly includes multiple connecting rods 405 and a pivot cylinder 408. The vertical cylinder 401 includes an upper cylinder 406 at the top, a lower cylinder 407 at the bottom, and a pivot cylinder 408 rotatably disposed between the upper cylinder 406 and the lower cylinder 407. An insert block is provided on the end face of the pivot cylinder 408, the cross-section of which is "T"-shaped. A first slot is provided on the bottom surface of the upper cylinder 406, the shape of which is adapted to the insert block. The top of the pivot cylinder 408 has an insert... The block is inserted into the first slot; a second slot is provided on the top surface of the lower cylinder 407, the shape of the second slot is adapted to the block, and the block at the bottom of the pivot cylinder 408 is inserted into the second slot; multiple insertion holes 409 are provided on the pivot cylinder 408, and the insertion holes 409 correspond one-to-one with the connecting rods 405. The connecting rods 405 pass through the corresponding insertion holes 409, and one end of the connecting rods 405 is connected to the screw conveyor rod 402, and the other end of the connecting rods 405 is connected to the spray ring 3.

[0047] The connecting rod 405 is designed so that the spray ring 3 can rotate with the rotation of the screw conveyor 402, saving space for a separate drive device for the spray ring 3. The pivot cylinder 408 is designed to prevent the vertical cylinder 401 from interfering with the rotation of the connecting rod 405 with the rotation of the screw conveyor.

[0048] Specifically, the filtration assembly includes a filter cylinder 410, a water storage cylinder 411, and a sealing device. The filter cylinder 410 is made of a filter screen that allows water to pass through. The filter cylinder 410 is cylindrical, and its top end is connected to the horizontal cylinder 4. The water storage cylinder 411 is cylindrical, and both ends of the water storage cylinder 411 are sealed. The top and bottom surfaces of the water storage cylinder 411 are provided with insertion holes 409. The diameter of the insertion holes 409 is the same as the outer diameter of the filter cylinder 410, and the height of the water storage cylinder 411 is the same as the height of the filter cylinder 410. The filter cylinder 410 is fixed in the insertion holes 409. The sealing device is rotatable and can seal or unseal the bottom end of the filter cylinder 410 by rotating. A return water pipe is provided between the water storage cylinder 411 and the water storage chamber 202.

[0049] In the initial state, the sealing device blocks the bottom of the filter cylinder 410. After the filter cylinder 410 is full, the screw conveyor 402 continues to supply dirt into the filter cylinder 410, which will increase the pressure inside the filter cylinder 410, thereby forcing water into the water storage cylinder 411, until the filter cylinder 410 stores a mud column made of dust. At this time, the blockage of the filter cylinder 410 can be released to discharge the mud column.

[0050] Preferably, the sealing device includes a sealing plate 412, a pressure sensor 413, a mounting plate 414, a drive unit, and a control unit 415. The pressure sensor 413 is mounted on the mounting plate 414, and the sealing plate 412 is mounted on the sensing end of the pressure sensor 413. The mounting plate 414 is connected to the drive unit, the pressure sensor 413 is connected to the control unit 415, and the control unit 415 is connected to the drive unit. The control unit 415 has a pressure preset value and a time preset value. In the initial state, the sealing plate 412 covers the bottom end of the filter cylinder 410. When the detection value of the pressure sensor 413 reaches the pressure preset value, the control unit 415 controls the drive unit to drive the mounting plate 414 to rotate, thereby releasing the sealing plate 412 from the filter cylinder 410. When the time for releasing the sealing reaches the time preset value, the control unit 415 controls the drive unit to drive the mounting plate 414 to rotate, so that the sealing plate 412 seals the bottom end of the filter cylinder 410.

[0051] When the filter cylinder 410 is filled with mud columns, the screw conveyor 402 continues to rotate. The mixture in the horizontal cylinder 4 pushes the mud columns downwards, causing the pressure sensor 413 to sense an increase in pressure until it reaches the preset pressure value. After a portion of the mud columns are discharged, the sealing plate 412 resets, and the bottom of the filter cylinder 410 is sealed by a small section of mud columns to prevent water in the water storage cylinder 411 from leaking out from the bottom of the filter cylinder 410.

[0052] Specifically, in this embodiment, the drive unit includes a pivot motor 416 and a pivot rod 417. The pivot motor 416 is mounted on the outer wall of the water storage cylinder 411, the top end of the pivot rod 417 is connected to the pivot motor 416, and the other end of the pivot rod 417 is connected to the mounting plate 414. A control component 415 is mounted on the side wall of the water storage cylinder 411 and is connected to the pivot motor 416. One end of the horizontal cylinder 4 extending to the outside of the dust collection box 2 is bent downward to form a push tube 418, and the filter cylinder 410 is connected to the push tube 418. The configuration of the pivot motor 416 and the pivot rod 417 is simple in structure and easy to use.

[0053] Finally, the bottom of the installation platform 1 is equipped with multiple casters 101, which can be locked and unlocked to facilitate the movement of the installation platform 1 and thus facilitate dust removal in different rooms.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
