Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology in building construction, and in particular to a high-efficiency dust removal device for green building construction. Background Technology

[0002] With the widespread adoption of green building concepts, environmental protection requirements at construction sites are becoming increasingly stringent, with dust control being a crucial indicator of civilized construction. In current construction processes, mobile spraying equipment is widely used to effectively reduce airborne dust concentration. This equipment utilizes high-pressure pumps to convert water into fine droplets, which then combine with suspended particles in the air and settle, thereby suppressing dust dispersion to some extent.

[0003] However, in practical use, it has been found that most existing dust removal equipment has relatively limited functions, generally only capable of spraying for high-altitude suspended dust. While this single operating mode can temporarily suppress dust in the air, it cannot effectively clean up the large amounts of dust accumulated on the ground, in corners, and in equipment gaps at construction sites. Once this dust is blown by wind, run over by vehicles, or disturbed by construction work, it is very easy for it to be re-entrained into the air, causing secondary pollution and making it difficult to maintain the dust removal effect in a long time.

[0004] To address these issues, some existing technical solutions attempt to incorporate suction functionality into dust collection equipment. However, their structural layout often lacks a systematic and comprehensive design. A common practice is to simply stack the water tank and dust collection box as two completely independent components on a mobile frame. This design not only results in a bulky and unstable overall device, severely limiting its mobility in confined and cluttered construction sites, but also, due to the lack of efficient use of water storage and dust collection space, it's difficult to balance the device's endurance and dust collection capacity within its limited volume. Furthermore, the adjustment mechanisms for spray operations are often simply designed, failing to achieve flexible, omnidirectional, and wide-angle adjustments, leading to numerous blind spots in dust collection and failing to meet the practical needs of green building construction for efficient, comprehensive, and convenient dust collection.

[0005] Therefore, this utility model proposes a high-efficiency dust removal device for green building construction to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems existing in the dust removal devices for green building construction, such as the single dust removal method, inability to flexibly deal with dust sources of different heights and dead corners, and the large size and inconvenience of moving and cumbersome maintenance and cleaning caused by the separation of water storage and dust collection structures, this utility model aims to provide a green building construction high-efficiency dust removal device with an improved structure that can effectively solve the above problems.

[0013] Preferably, the dust removal mechanism further includes a dust collection assembly, which includes a support plate, a dual-head extraction pump, an L-shaped inlet pipe, and a conical inlet. The support plate is fixedly connected to the partition plate on one side wall of the water storage area, and the dual-head extraction pump is fixedly installed on the top of the support plate.

The conical inlet is fixedly connected to the outer end of the L-shaped inlet pipe.

[0014] Preferably, the power assembly further includes a water pump and a water inlet hose.

[0025] Example: Reference Figures 1 to 6This embodiment provides a high-efficiency dust removal device for green building construction, which aims to solve the structural defects of existing construction dust removal equipment, such as single function, inability to simultaneously carry out high-altitude spraying and low-altitude dust collection, and the dispersed water storage and dust collection structures leading to large equipment size and difficulty in maintenance.

[0026] like Figure 1 As shown, the high-efficiency dust removal device for green building construction mainly consists of a support frame 1 as the main supporting skeleton, a dust removal mechanism 2 integrating multiple operation modes, a quick-release mechanism 3 for convenient filtration and maintenance, and a storage bin 4 for resource partitioning and storage. The dust removal mechanism 2, quick-release mechanism 3, and storage bin 4 are all reasonably arranged and installed on the support frame 1, thus forming a mobile integrated dust removal operation platform. The bottom of the support frame 1 can be equipped with rollers to improve the mobility of the device on the construction site. The support frame 1 provides a stable mounting base for the entire device.

[0027] Specifically, the storage tank 4 is fixedly installed at the rear of the support frame 1 for centralized treatment of water and dust, while the dust removal mechanism 2 is located at the front of the support frame 1 for performing specific dust removal operations. In order to achieve intensive use of the internal space of the storage tank 4, a partition plate 210 is fixedly connected inside the storage tank 4. The partition plate 210 is set vertically, physically dividing the inner cavity of the storage tank 4 into two independent and non-communicating areas, namely the water storage area on the right and the dust collection area on the left. This integrated partition design effectively solves the problem of traditional equipment requiring separate water tanks and dust tanks, which occupy too much space. At the same time, the partition plate 210 must have good sealing performance to prevent water in the water storage area from leaking into the dust collection area and causing mud blockage.

[0028] Reference Figure 1 In the specific construction of the dust removal mechanism 2, it includes a mechanical structure responsible for overall support and angle adjustment, and a power component 26 responsible for power output. The support base 21 serves as the basic component of the dust removal mechanism 2. Its bottom is firmly fixed to the front top of the support frame 1 by welding or bolt connection. The support plate 22 is horizontally fixed to the top surface of the support base 21, providing a stable bearing platform for the upper rotating components. The rotating plate 23 is rotatably connected to the top of the support plate 22 and can rotate horizontally relative to the support plate 22, thereby giving the spraying operation all-round coverage capability.

[0029] In order to drive the rotating disk 23 to achieve automated rotation, the motor 261 in the power assembly 26 is cleverly fixedly installed inside the support disk 22. The output shaft of the motor 261 extends vertically upward through the top surface of the support disk 22 and is fixedly connected to the bottom center of the rotating disk 23. When the motor 261 starts, it drives the rotating disk 23 to reciprocate 360 ​​degrees or a specified angle, thereby achieving horizontal adjustment of the spray direction.

[0030] Above the rotating disk 23, there is a component responsible for pitch adjustment. A support base 263 is fixedly connected to one side of the top of the rotating disk 23. The spray column 25, as the core component for performing the spraying action, is rotatably connected to the support base 263 at its bottom through pivot pins and other rotating parts, so that the spray column 25 can swing up and down with the support base 263 as the fulcrum. The cylinder 262 in the power component 26 is set in the internal space of the support base 263. The fixed end of the cylinder 262 is connected to the inner wall of the support base 263, and the telescopic end of the cylinder 262 extends out of the support base 263 and is hinged to the lower side of the outer wall of the spray column 25. When the cylinder 262 performs the extension or retraction action, it pushes the spray column 25 to rotate around the connection point, thereby realizing the pitch adjustment of the spray angle of the spray column 25 to adapt to the dust control needs at different heights.

[0031] In addition, in order to protect the spray column 25 and reduce the stress on the cantilever when the equipment is not in operation, two support blocks 24 are fixedly connected to the top surface of the rotating disk 23. The two support blocks 24 are symmetrically distributed on both sides below the swing path of the spray column 25, and the contact surface of the top of the support block 24 is designed as an arc-shaped concave surface that matches the shape of the outer wall of the spray column 25. When the cylinder 262 contracts to reset the spray column 25 to a horizontal state, the spray column 25 falls smoothly on the two support blocks 24, and the support blocks 24 bear the weight, avoiding long-term fatigue of the rotating joint.

[0032] Reference Figures 3 to 6 The dust collection assembly 27 has a support plate 271, a dual-head extraction pump 272, an L-shaped inlet pipe 273, and a conical inlet 274. The support plate 271 is fixedly connected to the side wall of the partition plate 210 facing the right side of the water storage area by welding or bolting. The installation position of the support plate 271 is located above the highest water level line of the water storage area. Its function is to provide a dry and stable installation platform for the dual-head extraction pump 272, while utilizing the unused space above the water storage area to avoid occupying the effective volume of the dust collection area on the left.

[0033] Meanwhile, corresponding through holes for pipes to pass through are provided on the side walls of the partition plate 210 and the storage bin 4. In the assembled state, the dual-head suction pump 272 is fixedly installed on the top surface of the support plate 271 as the source of vacuum suction negative pressure. One end of the L-shaped inlet pipe 273 is connected to the input end of the dual-head suction pump 272, and the other end of the L-shaped inlet pipe 273 horizontally passes through the support plate 271 and the side wall of the storage bin 4 and extends outward to the external environment of the storage bin 4. The conical inlet 274 is fixed. The L-shaped inlet pipe 273 is fixedly connected to the external end, and the flared mouth of the conical inlet 274 faces the ground or side to increase the capture area of ​​external suspended particles. The output end of the dual-head extraction pump 272 passes through the partition plate 210 through the air guide pipe and is connected to the interior of the dust collection area on the left side of the storage tank 4. Thus, when the dual-head extraction pump 272 is started, a negative pressure airflow circuit is formed between the L-shaped inlet pipe 273 and the dust collection area, which strongly draws in the external dust-laden air and transports it to the dust collection area for sedimentation and collection.

[0034] For the construction of the water circulation system of the spray system, the power component 26 also includes a water pump 265 and a water inlet hose 264. The water pump 265 is fixedly installed on the outer wall of the support base 263. The installation method allows the water pump 265 to rotate synchronously with the rotating disk 23 and the spray column 25, effectively preventing the pipes from getting tangled. One end of the water inlet hose 264 is connected to the inlet of the water pump 265, and the other end of the water inlet hose 264 hangs down into the bottom of the water storage area on the right side of the storage tank 4 to draw clean water. The outlet 28 of the water pump 265 is connected to the internal cavity of the spray column 25 through a pipe, thereby pressurizing the water in the water storage area and delivering it to the spray column 25 for atomization and spraying.

[0035] The quick-release mechanism 3 is integrated into the top water inlet of the storage tank 4. Specifically, the water inlet 31 is fixedly connected to the top surface of the water storage area on the right side of the storage tank 4. A through rectangular slot is opened inside the water inlet 31. The filter plate 32 is slidably connected inside the slot. The surface of the filter plate 32 is distributed with fine filter holes to intercept mud and solid impurities in the water when water is added to the water storage area, preventing impurities from entering the water storage area and clogging the nozzles of the water pump 265 and the spray column 25. The sealing plug 33 is made of elastic rubber material and is tightly inserted into the top opening of the water inlet 31 with an interference fit, thereby ensuring the sealing of the water storage area when no water is added and preventing external dust from falling into the water and causing secondary pollution.

[0036] To enhance the auxiliary dust removal function and efficiency of subsequent cleaning and maintenance, an adsorption plate 29 is installed on the outside of the storage tank 4. Several magnetic blocks a34 are embedded in the surface of the adsorption plate 29 facing the storage tank 4, and several magnetic blocks b35 are embedded in the corresponding positions on the outer wall of the storage tank 4. The adsorption plate 29 is detachably attached to the outer wall of the storage tank 4 by means of the magnetic adsorption between the magnetic blocks a34 and the magnetic blocks b35. The magnetic connection structure allows the operator to quickly remove the adsorption plate 29 by hand for rinsing or replacement without the need for tools such as screwdrivers, effectively maintaining the continuous adsorption capacity of the adsorption plate 29 for fine dust.

[0037] To facilitate the cleaning of accumulated dust in the dust collection area, the storage bucket 4 has an outlet 28 connected to the bottom of the outer wall on the left side of the dust collection area. The outer surface of the end of the outlet 28 is provided with external threads, and the matching sealing cap is screwed onto the outlet 28 by means of threaded connection. During the dust removal operation, the sealing cap is kept in a tight state to maintain the negative pressure environment in the dust collection area. When the dust in the dust collection area reaches a certain amount, the operator can unscrew the sealing cap to discharge the dust.

[0038] Regarding the stability and detail optimization of the structural connection, the bottom of the support base 21 is preferably fixed to the support frame 1 by welding or by high-strength bolts to ensure that the dust removal mechanism 2 remains stable and does not shake during the high-speed rotation of the motor 261 and the overall movement of the device. At the same time, the opening direction of the conical inlet 274 is set to face the bottom or side of the support frame 1 to facilitate the directional capture of dust on the ground or at low altitude. The L-shaped inlet pipe 273 is made of hard plastic or metal to prevent the pipe wall from collapsing and deforming due to pressure difference during negative pressure suction, ensuring that the airflow channel is always unobstructed.

[0039] The working principle is as follows: When the equipment enters the construction site and needs to carry out large-scale high-altitude dust suppression operations, the motor 261 in the power assembly 26 starts running first. The output shaft of the motor 261 rotates, driving the rotating disk 23 and the spray column 25 above it to rotate horizontally relative to the support disk 22, thereby determining the horizontal orientation of the spraying operation. Then, the cylinder 262 located inside the support base 263 performs an extension or retraction action. Since the end of the cylinder 262 is hinged to the outer wall of the spray column 25, the linear motion of the cylinder 262 pushes the spray column 25 to swing up and down around its rotation connection point with the support base 263, thereby precisely adjusting the pitch angle of the spray column 25 to aim at the dust source. After the angle is locked, the water pump 265 starts working, drawing clean water filtered by the filter plate 32 from the water storage area on the right side of the storage tank 4 through the water inlet hose 264. The water is pressurized and delivered to the interior of the spray column 25 and atomized and sprayed outward. The water mist combines with the suspended particles in the air, causing them to increase in weight and settle, thus completing the high-altitude active dust suppression.

[0040] For areas with ground-accumulated dust or high-concentration dust at low altitudes, the dust collection component 27 is put into operation. The dual-head extraction pump 272, fixed on the support plate 271, is started, generating a strong negative pressure suction at the L-shaped inlet pipe 273 and the conical inlet 274. External dust-laden air is rapidly sucked into the conical inlet 274 under the action of pressure difference, and then transported through the L-shaped inlet pipe 273 through the support plate 271 and the side wall of the storage tank 4 to the dust collection area on the left side of the storage tank 4. Dust particles settle and accumulate in the dust collection area due to gravity. This not only solves the problem of difficult dust removal in local dead corners, but also, due to the sealing and isolation effect of the partition plate 210, the dust collection process and the water storage function of the water storage area do not interfere with each other, realizing the combined function of water spraying and air dust collection on one device.

[0041] Throughout the entire operation of the equipment, the adsorption plate 29, which is magnetically connected to the outer wall of the storage tank 4 by magnetic blocks a34 and b35, continuously performs passive physical adsorption of fine dust around the equipment. When there is too much dust on the surface of the adsorption plate 29 or when the dust collection area is full of dust, the operator can directly pull down the adsorption plate 29 by hand for rinsing and cleaning, and unscrew the sealing cap located at the outlet 28 to discharge the dust in the dust collection area. When water needs to be added, the sealing plug 33 is pulled out and water is injected through the water inlet 31. The filter plate 32 is used to prevent mud and sand from entering the water storage area. This comprehensive quick-disassembly and maintenance design significantly improves the continuity and convenience of dust removal operations at green building construction sites.
