Description

Technical Field

[0001] The invention relates to the technical field of dust suppressors, in particular to an environmentally friendly dust suppressor for construction. Background Art

[0002] With the rapid development of industrialization and urbanization, the problem of air pollution is becoming increasingly serious. Dust pollution has become a global environmental problem. Dust particles are small and easily suspended in the air, and are not easy to settle. They not only have a serious impact on human health, but also damage the ecological environment. Therefore, it has become an urgent task to develop efficient and environmentally friendly dust reduction equipment to reduce the dust content in the atmosphere. In the construction industry, due to frequent construction activities, the problem of dust pollution is particularly prominent. Therefore, it is particularly important to develop an efficient and environmentally friendly dust reduction machine for construction: The announcement number CN116078086A discloses a water-saving dust reduction device and dust reduction method for ecological environment protection, which belongs to the field of dust reduction technology. It includes a base plate, and also includes: a collecting cylinder fixedly connected to the surface of the base plate, the inner wall of the collecting cylinder is fixedly connected to a filter; a dust reduction box fixedly connected to the surface of the base plate, the inner wall of the dust reduction box is fixedly connected to a suction pump, and a water inlet pipe is fixedly connected between the dust reduction box and the collecting cylinder; a first water outlet pipe fixedly connected to the outlet end of the suction pump, the outlet end of the first water outlet pipe is fixedly connected to a water distribution plate, the water distribution plate is hollow, and the bottom of the water distribution plate is symmetrically fixedly connected to a spray generator, and the output end of the spray generator is fixedly connected to a nozzle, and by using the collected rainwater for dust reduction treatment, water resources are saved, which is beneficial to the protection of the ecological environment; When the above-mentioned prior art is used, the nozzle is used to spray water to reduce dust on the construction site. However, in the actual dust reduction process, the height of the nozzle is adjusted by using a motor in conjunction with components such as a slide plate, and water can only be sprayed in a single direction and range to reduce dust. When the nozzle height is too high, the sprayed water mist may not be able to fully cover the dust on the ground or in the low-altitude area, resulting in poor dust reduction effect. On the contrary, when the nozzle height is too low, the sprayed water mist may be too concentrated and cannot be effectively spread to a wider area. If full-range dust reduction is required, the nozzle height needs to be adjusted frequently, which is cumbersome to operate and easily causes equipment damage. Therefore, corresponding improvements are needed; In a dust suppressor for construction projects with announcement number CN108607293A, the technical problem to be solved by the present invention is to provide a dust suppressor for construction projects with simple operation and a large dust reduction range. In order to solve the above technical problems, the present invention provides such a dust suppressor for construction projects, including a base, a water tank, a water pump, a first water outlet pipe, a first air pipe, an atomizing nozzle, a compression cylinder, a piston, a water inlet pipe, a second water outlet pipe, a one-way valve, etc.; a water tank is provided on the top of the base, a water pump is installed on the left side of the top of the water tank, the water pump is connected to the first water outlet pipe, the upper left part of the water tank is connected to the first air pipe, and the end of the first water outlet pipe passes through the first air pipe and is connected to the atomizing nozzle. The present invention can make the water in the water tank spray out from the atomizing nozzle through the first water outlet pipe through the operation of the water pump to reduce dust, and the atomizing nozzle can be driven to rotate forward and reversely through the forward and reverse rotation of the second motor to increase the spray range, thereby achieving the effect of simple operation; When the above-mentioned prior art is in use, water is sprayed to reduce dust under the coordinated action of a water pump and a nozzle, wherein the nozzle can only rotate forward and reverse to increase the spray range, but water can only be sprayed in a single direction to reduce dust at a time, and the spraying range is small, so that some areas cannot be effectively covered by water mist, thereby affecting the dust reduction effect and reducing the dust reduction efficiency. It takes longer time or more water resources to achieve the expected dust reduction effect. Therefore, corresponding improvements are needed. Summary of the invention

[0003] The object of the present invention is to provide an environmental protection type dust suppressor for construction, so as to solve the problem of low water spraying dust suppression efficiency of the existing environmental protection type dust suppressor for construction proposed in the above background technology when in use.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: an environmental protection type dust suppressor for construction, comprising a dust suppressor body, a rotating ring, a supporting ring, and a top platform, wherein the top of the dust suppressor body is sleeved with the supporting ring, and the outer side of the supporting ring is sleeved with the rotating ring, and the top platform is fixed to the top of the dust suppressor body; Also includes: Extension frames are evenly fixed on the outside of the top platform, and the top platform and multiple extension frames are integrally formed.

A swing assembly is provided on one side of the bottom end of the connecting frame, and a dust reduction spray assembly is connected to one side of the swing assembly. A power rotating mechanism is provided on the outside of the dust reducer main body below the rotating ring.

[0005] Furthermore, a limiting outer ring is fixed on the outside of the support ring, a guide groove is provided on the inner wall of the rotating ring, the width of the guide groove matches the width of the limiting outer ring, and the rotating ring rotates circumferentially on the outside of the support ring.

[0006] Furthermore, the swing assembly includes a supporting square tube fixed to the bottom end of the connecting frame, and a swing arm is hinged on one side of the supporting square tube, the cross-section of the swing arm is U-shaped, a swing hinge frame is fixed on one side of the inside of the swing arm, hinge seats are fixed at both ends of the swing arm, and a damping member is connected between the hinge seat and the base frame.

[0007] Furthermore, three dust reduction spray assemblies are arranged on the periphery of the top platform and are distributed in a ring shape on the periphery of the top platform. One group of the spray assemblies includes two dust reduction sprinkler pipes, which are respectively arranged on both sides of the swing hinge frame. Atomizing nozzles are evenly arranged on the dust reduction sprinkler pipes. One end of the dust reduction sprinkler pipe is connected to a water receiving hose, and one side of the water receiving hose is connected to a water guide pipe. One end of the water guide pipe is connected to an external water supply device, and a distance adjustment assembly is arranged at the bottom of the dust reduction sprinkler pipe.

[0008] Furthermore, the distance adjustment component includes an adjustment rail fixed to one side of the swing hinge frame, and both ends of the outer side of the adjustment rail are slidably connected with adjustment sliders, the bottom end of the adjustment slider is connected to a hollow angle bracket, and the top end of the hollow angle bracket is connected to a supporting arm, and the top end of the supporting arm is connected to the bottom end of the dust reduction sprinkler pipe.

[0009] Furthermore, four adjusting sliders are provided, all of which are fixedly connected to the top of the hollow angle frame. The adjusting sliders slide on the adjusting guide rails, and the dust reduction sprinkler pipe is slidably connected to the swing hinge frame through the adjusting sliders and the adjusting guide rails.

[0010] Furthermore, three extension frames are arranged on the outside of the top platform and are distributed in a ring shape on the outside of the top platform. Three groups of dust suppression sprinkler pipes are arranged, and two are arranged in each group.

[0011] Furthermore, the power rotation mechanism includes a driving motor, and the driving motor is connected to the outer wall of the dust suppressor body through a support plate, the output shaft end of the driving motor is connected to a rotating main shaft, and a power gear is fixed to one end of the rotating main shaft, and a gear ring is meshed on one side of the power gear, and the gear ring is arranged at the bottom of the rotating ring.

[0012] Furthermore, a ring-shaped tooth groove is arranged at the bottom of the rotating ring, the tooth ring is arranged in the tooth groove, and an impact bump is connected to the outer edge of the rotating ring.

[0013] Furthermore, the damping member includes a sleeve, a piston rod and a telescopic spring. The sleeve is movably connected to the base frame, and the piston rod is movably connected to the swing arm through a hinge seat.

One end of the rubber plug is connected to a telescopic spring, and the telescopic spring is connected to the interior of the sleeve.

[0014] Compared with the prior art, the invention has the following beneficial effects: the environmental protection type dust suppressor for construction can spray water to suppress dust in all directions, so as to expand the dust suppression range of a single spray, thereby improving the dust suppression efficiency; and the dust suppression water pipe can swing up and down to expand the dust suppression range of the water spray, which helps to enhance the dust suppression effect and efficiency; During the dust reduction process at the construction site, the driving motor is used to drive the rotating main shaft and the power gear to rotate, and the power gear and the gear ring are meshed with each other to rotate the gear ring and rotate around the outer periphery of the support ring. In this process, the cooperation of the guide groove and the limiting outer ring can be used as the rotation limiting guide of the rotating ring. In this process, the rotating ring rotates to make the impact convex block rotate synchronously. During the rotation of the impact convex block, it contacts the swing arm, thereby lifting the swing arm and turning the swing arm upward, so that the swing hinge frame and the dust reduction sprinkler pipe can be turned upward synchronously. When the impact convex block continues to rotate away from the swing arm, the swing hinge frame and the dust reduction sprinkler pipe swing downward. The whole movement process makes the swing hinge frame and the dust reduction sprinkler pipe swing up and down, which can change the spraying direction and angle of the water mist, so that the water mist covers every corner of the construction area more widely. This swinging method helps to ensure that the water mist is fully in contact with the dust particles in the air, so as to more effectively adsorb and settle the dust and improve the dust reduction efficiency. There are three dust suppression spraying components, which are distributed in a ring shape around the top platform. There are six dust suppression water pipes, and a number of atomizing nozzles are set on the dust suppression water pipes. When spraying water to suppress dust, it can form a 360-degree full coverage, ensuring that the water mist can be evenly sprayed in all directions of the construction area without leaving dead corners, thereby effectively suppressing the spread of dust and further improving the dust suppression efficiency; Furthermore, by moving the dust reduction sprinkler pipe, making the adjustment slider slide on the adjustment guide rail, and making the hollow angle frame move synchronously, the position of the dust reduction sprinkler pipe can be adjusted accordingly, and the spacing between the corresponding dust reduction sprinkler pipes can be adjusted, allowing the spraying range between the two dust reduction sprinkler pipes to be adjusted according to actual needs. In areas where key dust reduction is required, the density of water mist can be increased by reducing the spacing between the two dust reduction sprinkler pipes, thereby more effectively adsorbing and settling dust and ensuring the optimization of the dust reduction effect.

The sprayed water can more effectively cover and absorb dust particles in the air. Compared with the traditional manual watering method, the water spraying of the atomizing nozzle 1201 can save a lot of water resources. The water atomized particles are small and have a large surface area, and are in more complete contact with the dust particles in the air, thereby improving the dust suppression efficiency. Then, the driving motor 1401 is used to drive the rotating main shaft 1404 and the power gear 1402 to rotate.

The swing hinge frame 7 and the dust-reducing water pipe 12 are rotated so as to synchronously turn upwards. When the impact protrusion 203 continues to rotate away from the swing arm 8, the swing hinge frame 7 and the dust-reducing water pipe 12 swing downwards. The whole movement process causes the swing hinge frame 7 and the dust-reducing water pipe 12 to swing up and down, which can change the spraying direction and angle of the water mist, so that the water mist can cover every corner of the construction area more widely, so that the three groups of dust-reducing water pipes 12 on the periphery of the top platform 4 swing up and down at intervals, thereby improving the overall dust reduction efficiency, and the overall operation process only uses a single driving member. It can be achieved, which is helpful to achieve the effect of protecting resources and saving environment. In addition, during the up and down swinging of the swing arm 8 and the dust reduction sprinkler pipe 12, the damping member 9 can achieve the effect of support and rapid reset, which is helpful to increase the swing frequency. Among them, when the swing arm 8 is swung up, the piston rod in the damping member 9 extends outward in the sleeve and stretches the telescopic spring in the sleeve. When the impact protrusion 203 moves away from the swing arm 8, the telescopic spring is reset, so that the swing arm 8 and the dust reduction sprinkler pipe 12 are quickly swung down, so as to support and reset the up and down swinging of the swing arm 8.
