Description

Technical Field

[0001] The present invention relates to the technical field of water spray dust removal, and specifically relates to a water spray dust removal device for construction engineering. Background Art

[0002] Water spray dust removal is an effective air purification and dust reduction technology, which is used to reduce the impact of dust and particulate matter on air quality. By spraying water mist, dust particles in the air are captured and settled, thereby improving the cleanliness of the air. It is widely used in the construction process.

[0003] In the prior art, a Chinese patent with the application number CN201911293261.6 discloses a water spray dust removal device for green building construction. Aiming at the problem that there is no corresponding dust removal device at the existing construction site, resulting in flying dust floating from the construction site to the nearby residential area, and thus bringing environmental pollution to the surrounding residents, the following solution is proposed. It includes mounting seats detachably and fixedly installed on both sides of the wall. Both sides of the mounting seat are slidably connected with dust removal seats. A lifting component is fixedly connected to the mounting seat, and the lifting component is fixedly connected to one side of the dust removal seat. A dust suction component is arranged in the dust removal seat. A water pipe network is arranged on the dust removal seat, and a plurality of water spray heads with different spraying angles are arranged on the water pipe network to achieve multi-directional and three-dimensional dust removal. At the same time, assisted by air suction dust removal, the dust removal effect can be better improved, and it has strong practicability.

[0004] In the prior art, a Chinese patent with the application number CN202311668906.6 discloses a water spray dust removal device for green building construction, which relates to the technical field of dust removal equipment. It includes a support frame plate, rollers, a push handle and an adjustable dust removal component. The adjustable dust removal component includes a lifting unit, a watering unit and a storage unit. The lifting unit includes a lifting frame, a guiding slide rod, a threaded rod, a driving motor, an auxiliary frame and a positioning plate. By using the cooperation of the driving motor, the guiding slide rod, the threaded rod, the lifting frame and the positioning plate, the first watering plate and the second watering plate can be adjusted in height according to requirements, improving the applicability to the dust removal requirements of the dust removal environment. By using the cooperation of the electric push rod, the shaft seat, the lifting frame and the auxiliary frame, the first watering plate and the second watering plate can adjust the angle between themselves and the ground as needed, so that the first watering plate and the second watering plate can perform dust removal work more flexibly.

[0005] For another example, in the prior art, a Chinese patent with the application number CN202010862437.1 discloses an efficient water spraying device for dust removal at a construction site, which includes a fixed base. A water storage tank is installed on the left side of the upper end of the fixed base. A fixed plate is horizontally installed on the upper end of the water storage tank. A stirring shaft is horizontally installed inside the water storage tank. The right end of the stirring shaft passes through the right wall of the water storage tank and is connected with a driving gear. The upper and lower positions on the right end of the driving gear are respectively engaged with driven gears. A upper rotating shaft is installed in the middle of the upper end of the upper driven gear. An upper rotating gear is installed in the middle of the upper rotating shaft. A lower rotating shaft is installed in the middle of the lower end of the lower driven gear. A lower rotating gear is installed in the middle of the upper end of the lower rotating shaft. Rotating gears are respectively engaged with the right sides of the upper rotating gear and the lower rotating gear. A rotating shaft is vertically installed between the rotating gears, realizing the clockwise and counterclockwise swinging of the rotating shaft, so that the water spray head can spray water for dust removal in a swinging manner, greatly increasing the dust removal effect. And a water diversion tank and a water inlet tank are provided, which further increases the water spraying effect.

[0006] Combined with the above materials, it can be seen that the existing water spraying dust removal devices generally atomize water and spray it to achieve the purpose of dust settlement. However, in the actual use process, water spraying dust removal only settles the dust in the air to the ground. When the water evaporates, the dust on the ground will still fly into the air again. Therefore, the overall dust removal effect is not thorough. Summary of the Invention

[0007] The purpose of the present invention is to provide a water spraying dust removal device for construction projects to solve the problem of incomplete dust removal effect proposed in the above background technology.

A first pump body is fixedly installed on the upper surface of the water storage tank. A lifting pipe is fixedly installed at the water inlet of the first pump body, and a spray pipe is fixedly installed on the upper surface of the water storage tank. The spray pipe is communicated with the water outlet of the first pump body through a delivery pipe. A first atomizing nozzle is fixedly installed on the side of the spray pipe, and an installation sleeve is arranged at the upper end of the spray pipe. A second atomizing nozzle is rotatably installed on the side of the installation sleeve, and a reciprocating mechanism for driving the second atomizing nozzle to rotate is arranged between the installation sleeve and the spray pipe. A dust collector is installed on the side of the support base. A dust collection box is fixedly installed outside the side of the water storage tank. A second pump body is installed at the bottom end inside the dust collection box, and the second pump body is communicated with the dust collector through a first connecting pipe. A pushing mechanism corresponding to the dust collector is arranged inside the support base.

[0009] Preferably, the dust collection box is integrally made of high-carbon steel, and a pressure gauge for detecting the internal pressure is fixedly installed on the outer surface of the dust collection box, and a filter screen is fixedly installed at the upper end inside the dust collection box.

[0010] Preferably, a second connecting pipe is fixedly installed through the upper surface of the dust collection box, and the upper end of the second connecting pipe is interconnected with the conveying pipe through an electric control valve.

[0011] Preferably, the pushing mechanism includes a torsion spring fixedly installed outside the rotating shaft of the vacuum cleaner, and friction rollers and moving rollers rotatably installed outside the front and rear sides of the support base.

[0012] Preferably, the moving roller is driven by a motor inside the support base, and the outer surface of the moving roller corresponds to and rubs against the outer surface of the friction roller.

[0013] Preferably, a reciprocating lead screw is rotatably installed inside the support base, and the reciprocating lead screw is fixedly connected to the friction roller, and a connecting slider is installed through the outside of the reciprocating lead screw.

[0014] Preferably, a push rod is fixedly installed on the outer surface of the front end of the connecting slider, and the position of the push rod corresponds to the upper end of the vacuum cleaner, and the push rod and the support base form a penetrating sliding structure.

[0015] Preferably, the reciprocating mechanism includes a mounting plate fixedly installed at the upper end of the spray pipe, and an annular extrusion table is fixedly installed on the upper surface of the mounting plate, and a curved undulating structure is arranged on the upper surface of the extrusion table.

[0016] Preferably, an extrusion ball matching the extrusion table is arranged above the extrusion table, and a vertical connecting rod is fixedly installed at the upper end of the extrusion ball, and the connecting rod and a limit block fixedly installed on the lower surface of the mounting sleeve form a penetrating sliding structure.

[0017] Preferably, the upper end of the connecting rod is rotatably connected to the second atomizing nozzle, and a power nozzle is fixedly installed at the lower end of the mounting sleeve, and the power nozzle is arranged in an inclined structure.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The water spraying and dust removal equipment for construction engineering adopts a new structural design, and the specific content is as follows: 1. The water in the water storage tank is conveyed to the spray pipe through the first pump body, and then sprayed out from the first atomizing nozzle and the second atomizing nozzle to achieve the purpose of dust reduction in the surrounding environment. During this process, the second pump body is synchronously started to make the vacuum cleaner generate suction, so as to suck the dust on the ground into the dust collection box for collection, thereby reducing the dust on the ground and avoiding subsequent re-scattering, achieving a more thorough dust reduction effect; Further, the dust collection box is made of high-strength material, so it can store a large amount of air and pressurize it during dust suction. When the work stops, the electric control valve is opened. At this time, the pressurized air in the dust collection box enters the conveying pipe through the second connecting pipe, so as to use the extrusion air flow to dredge the first atomizing nozzle and the second atomizing nozzle, avoiding blockage during long-term use. Furthermore, when the device works, it moves through the moving rollers. The friction force of the moving rollers drives the friction rollers to rotate, so that the friction rollers drive the reciprocating screw rod to rotate. During the rotation of the reciprocating screw rod, the connecting slider installed through the external thread is driven to move reciprocally, so as to use the push rod outside the connecting slider to push the vacuum cleaner to rotate. Then, with the cooperation of the torsion spring, the vacuum cleaner is reset, and finally the vacuum cleaner rotates reciprocally, thus expanding its dust suction range.

[0019] 2. Part of the water in the spray type is sprayed out from the power nozzle. Since the power nozzle is set in an inclined structure, it drives the installation sleeve to rotate under the action of the reaction force, so that the installation sleeve drives the second atomizing nozzle to rotate, expanding the spraying range of the second atomizing nozzle. Further, the rotation of the installation sleeve drives the connecting rod to rotate synchronously. At this time, the cooperation between the extrusion ball at the lower end of the connecting rod and the undulating structure on the upper surface of the extrusion table is used, so that the connecting rod drives the second atomizing nozzle to rotate up and down (the connecting rod is limited by the limit block), further expanding the spraying range of the second atomizing nozzle.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0023] Embodiment 1: Please refer to Figures 1 - 5 , in order to achieve the purpose of thorough dust removal in this embodiment, the following technical solutions are provided, and specifically disclosed: a horizontally arranged support base 1, a water storage tank 2 with a filling pipe 201 fixedly installed on the upper surface of the support base 1, and a control panel 3 fixedly installed on the outer surface of the water storage tank 2. A first pump body 4 is fixedly installed on the upper surface of the water storage tank 2. A lifting pipe 5 is fixedly installed at the water inlet position of the first pump body 4. And a spraying pipe 6 is fixedly installed on the upper surface of the water storage tank 2. The spraying pipe 6 is communicated with the water outlet position of the first pump body 4 through a delivery pipe 7. A first atomizing nozzle 8 is fixedly installed on the side of the spraying pipe 6. And an installation sleeve 9 is arranged at the upper end of the spraying pipe 6. A second atomizing nozzle 10 is rotatably installed on the side of the installation sleeve 9. A vacuum cleaner 11 is installed on the side of the support base 1. A dust collection box 12 is fixedly installed outside the side of the water storage tank 2. A second pump body 13 is installed at the bottom end inside the dust collection box 12. And the second pump body 13 is communicated with the vacuum cleaner 11 through a first connecting pipe 14. The dust collection box 12 is made of high-carbon steel as a whole. And a pressure gauge 1201 for detecting the internal pressure is fixedly installed on the outer surface of the dust collection box 12. And a filter screen 15 is fixedly installed at the upper end inside the dust collection box 12. A second connecting pipe 16 is fixedly installed through the upper surface of the dust collection box 12. The upper end of the second connecting pipe 16 is mutually communicated with the delivery pipe 7 through an electric control valve 17.

[0024] When using the device, first inject clean water into the water storage tank 2 through the filling pipe 201. Then, start the motor inside the support base 1 to drive the moving roller 18 to rotate, so that the moving roller 18 drives the whole device to move. During the moving process, finally start the first pump body 4. At this time, the first pump body 4 transports the water in the water storage tank 2 to the conveying pipe 7 through the lifting pipe 5, and then enters the spray pipe 6, and finally sprays out through the first atomizing nozzle 8 and the second atomizing nozzle 10 to achieve the purpose of dust removal for the surrounding environment. During this process, simultaneously start the second pump body 13 inside the dust collection box 12. The second pump body 13 generates negative pressure at the position of the dust collector 11 through the first connecting pipe 14. Under the action of the negative pressure, the dust on the ground is sucked into the dust collection box 12. The inhaled air and dust are stored in the dust collection box 12 (since the dust collection box 12 is made of high-strength material, it can withstand greater pressure, and at the same time, the pressure gauge 1201 on the outer surface of the dust collection box 12 is used to detect the pressure inside the dust collection box 12). When the dust reduction is completed, the device stops running. At this time, open the electric control valve 17. The pressurized air in the dust collection box 12 enters the conveying pipe 7 through the second connecting pipe 16, and then reaches the positions of the first atomizing nozzle 8 and the second atomizing nozzle 10 in turn. Under the action of the pressurized air flow, the first atomizing nozzle 8 and the second atomizing nozzle 10 are cleaned to prevent them from being blocked during long-term use.

[0025] Embodiment 2: Please refer to Figures 6 - 7 , in order to achieve the purpose of expanding the dust suction range in this embodiment, the following technical solutions are provided. Specifically disclosed is that a pushing mechanism corresponding to the dust collector 11 is arranged inside the support base 1. The pushing mechanism includes a torsion spring 23 fixedly installed outside the rotating shaft of the dust collector 11, and friction rollers 19 and moving rollers 18 rotatably installed outside the front and rear sides of the support base 1. The moving roller 18 is driven by a motor inside the support base 1, and the outer surfaces of the moving roller 18 and the friction roller 19 correspond to each other and rub. A reciprocating lead screw 20 is rotatably installed inside the support base 1, and the reciprocating lead screw 20 is fixedly connected to the friction roller 19. And a connecting slider 21 is installed through the outside of the reciprocating lead screw 20. A push rod 22 is fixedly installed on the front outer surface of the connecting slider 21, and the position of the push rod 22 corresponds to the upper end of the dust collector 11. And the push rod 22 and the support base 1 form a through-type sliding structure.

[0026] During the movement of the device, the moving roller 18 rotates. The frictional force on the surface of the moving roller 18 drives the friction roller 19 to rotate. During the rotation of the friction roller 19, the reciprocating lead screw 20 inside the support base 1 is driven to rotate. The rotation of the reciprocating lead screw 20 drives the connecting slider 21 installed through the external thread to reciprocate. Thus, the push rod 22 outside the connecting slider 21 is used to push the vacuum cleaner 11 to rotate. Then, under the action of the torsion spring 23, the vacuum cleaner 11 is reset. In this way, the vacuum cleaner 11 rotates reciprocally, thereby expanding the dust suction range of the vacuum cleaner 11 and achieving a better use effect.

[0027] Embodiment 3: Please refer to Figures 8 - 10 , in order to achieve the purpose of expanding the spraying range in this embodiment, the following technical solutions are provided, and specifically disclosed: A reciprocating mechanism for driving the second atomizing nozzle 10 to rotate is provided between the mounting sleeve 9 and the spray pipe 6. The reciprocating mechanism includes a mounting plate 24 fixedly installed at the upper end of the spray pipe 6, and an annular extrusion table 25 is fixedly installed on the upper surface of the mounting plate 24. Moreover, the upper surface of the extrusion table 25 is provided with a curved undulating structure. An extrusion ball 27 matching the extrusion table 25 is arranged above the extrusion table 25. A vertical connecting rod 26 is fixedly installed at the upper end of the extrusion ball 27. The connecting rod 26 and the limiting block 28 fixedly installed on the lower surface of the mounting sleeve 9 form a through-type sliding structure. The upper end of the connecting rod 26 is rotatably connected to the second atomizing nozzle 10. A power nozzle 29 is fixedly installed at the lower end of the mounting sleeve 9, and the power nozzle 29 is arranged in an inclined structure.

[0028] During the process of spray dust suppression, a part of the water in the spray pipe 6 is sprayed out from the power nozzle 29. Since the power nozzle 29 is arranged in an inclined structure, the reaction force of the power nozzle 29 is used to drive the mounting sleeve 9 to rotate. Thus, the mounting sleeve 9 drives the second atomizing nozzle 10 to rotate horizontally, expanding the spraying range of the second atomizing nozzle 10. During the rotation of the mounting sleeve 9, the connecting rod 26 outside it will be driven to rotate. At this time, the extrusion ball 27 at the lower end of the connecting rod 26 cooperates with the upper surface of the extrusion table 25. Since the upper surface of the extrusion table 25 is an undulating arc structure, the connecting rod 26 will move up and down (when the connecting rod 26 moves up and down, the limiting block 28 is used to cooperate with the groove inside it for limiting). The up and down movement of the connecting rod 26 is used to drive the second atomizing nozzle 10 to rotate up and down, thereby further expanding the spraying range of the second atomizing nozzle 10.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
