Description

Technical Field

[0001] The present invention relates to the technical field of air pollution control, and particularly to a construction spraying dust reduction device. Background Technique

[0002] The spraying dust reduction technology has been widely used in construction, mainly to deal with the dust problems generated during the construction process. Operations such as earth excavation, concrete pouring, and material transportation will generate a large amount of dust, which not only affects the air quality at the construction site but also has a negative impact on the health and living environment of surrounding residents. The spraying dust reduction technology atomizes water into tiny water droplets and sprays them into the air to form a water mist layer to reduce the dust concentration in the air. The atomized water droplets can cover a larger area, and the dust reduction effect is obvious. The water consumption for spraying dust reduction is less, reducing the waste of water resources. This technology does not use chemical agents and is environmentally friendly. The spraying dust reduction technology plays an important role in construction, being able to effectively control dust and improve the safety and health of the construction environment.

[0003] A construction spraying dust reduction device with the publication number CN117298773A includes a box body. The box body also includes a disassembly device, and the disassembly device includes a rotating mechanism and a sliding structure. The rotating mechanism includes a bracket, a rotating wheel, and a pneumatic telescopic rod. The bracket is arranged above the box body, the rotating wheel is fixedly connected below the bracket, and the pneumatic telescopic rod is hinged above the rotating wheel.

The U-shaped slide rail is fixedly connected above the box body, the screw rod is threadedly connected inside the U-shaped slide rail, the turning handle is fixedly connected to the front side of the screw rod, and the switch is hinged to the rear side of the U-shaped slide rail. The rotating wheel is slidably connected to the inside of the U-shaped slide rail. However, this patent has the problem that the water spraying range is limited and the dust reduction effect is not good enough. Therefore, it is very necessary to design a construction spraying dust reduction device. Summary of the Invention

[0004] The purpose of the present invention is to provide a construction spraying dust reduction device to solve the problems raised in the above background technique.

During operation, an external motor drives the first rotating rod and the second rotating rod to rotate, and the large fan blade and the small fan blade rotate simultaneously to extract air, increasing the wind force to atomize the sprayed water. The atomizing direction of the device can be adjusted 360 degrees by manually rotating the large turntable. At the same time, the hydraulic rod can adjust the angle of the device up and down, which is convenient for operation, thereby expanding the scope of atomizing dust reduction.

[0006] According to the above technical solution, the atomizing mechanism includes a circular tube, and eight T-shaped tubes are rotatably connected to the surface of the circular tube. A loop is fixedly connected to the side of each T-shaped tube. A water spray head is fixedly connected to one end of each T-shaped tube away from the atomizing mechanism. One end of the loop away from the T-shaped tube is slidably connected to a first ring. Two long rods are slidably connected to the inner side of the first ring. Four elastic ropes are fixedly connected to the side of the first ring. Two L-shaped strips are fixedly connected to the side of the first ring. A first water outlet pipe is fixedly connected to the bottom of the circular tube. A second ring is fixedly connected to the outer surface of the housing. The circular tube is fixedly connected to the housing. The first ring is located within the eight loops. The L-shaped strip is slidably connected to the second ring. The L-shaped strip is fixedly connected to the small turntable. The first water outlet pipe passes through the circular hole of the large turntable and the box body. The first water outlet pipe is fixedly connected to the water pump. When the small turntable rotates to pull the L-shaped strip, the first ring is forced to reciprocate within the loop, thereby pulling the T-shaped tube to rotate around the circular tube, so as to adjust the water spraying angle of the water spray head, which can expand the atomizing range and improve the atomizing and dust reduction efficiency of the device.

[0007] According to the above technical solution, the cleaning mechanism includes a cylindrical tube.

A small brush is fixedly connected to one end of the connecting rod away from the sliding strip. The third rotating rod is slidably connected to the screen and penetrates the screen. A groove is formed on the side of the brush. The small brush is located within the groove of the brush. A spring is arranged inside the cylindrical tube, and both ends of the spring are fixedly connected to the cylindrical tube and the third rotating rod respectively. When the cylindrical tube rotates with the first rotating rod, the third rotating rod drives the brush to perform a circular motion to clean the dust on the screen. During the rotation of the brush, the sliding strip slides from the inside to the outside within the groove of the brush, thereby driving the small brush to rotate and clean the dust in the gaps of the screen. When the third rotating rod slides along the screen, the brush contacts the four bumps on the screen and shakes. At this time, the third rotating rod extends outwards from the cylindrical tube and stretches the spring. When the brush disengages from the bump, the third rotating rod resets under the action of the spring and pulls the brush to strike and clean the screen, shaking off the dust attached to the screen after cleaning, preventing dust accumulation and improving the cleaning efficiency.

[0008] According to the above technical solution, the water storage mechanism includes a water bucket. One side of the water bucket close to the water pump is fixedly connected with a second water outlet pipe. A filter screen is fixedly connected inside the water bucket. An empty ball is arranged above the filter screen. The inner wall of the top of the water bucket is fixedly connected with a water inlet cylinder. Two water outlet holes are opened on the side surface of the water inlet cylinder. A sealing plug is arranged inside the water inlet cylinder. A small square block is fixedly connected to the bottom of the sealing plug. The top of the water bucket is fixedly connected with a water inlet pipe. The second water outlet pipe is fixedly connected with the water pump. The empty ball is located below the small square block. The water inlet cylinder is fixedly connected with the water inlet pipe. A hole of the same size as the small square block is opened at the bottom of the water inlet cylinder. The water inlet cylinder is slidably connected with the small square block. When the water pump works, an external water source enters the water bucket from the water inlet pipe. The filter screen can filter impurities to prevent the spray head from being blocked. When the water level reaches a certain height, the empty ball moves upward due to the buoyancy force, squeezing the small square block to move upward until the sealing plug blocks the connection port between the water inlet cylinder and the water inlet pipe, thereby stopping the water pumping and realizing automatic control of the water volume in the water bucket.

At the same time, the hydraulic rod can adjust the angle of the device up and down, which is convenient for operation, thereby expanding the atomization and dust reduction range. In the present invention, by providing an atomization mechanism, a circular tube, a T-shaped tube, a ring buckle, a spray head, a first ring, a long rod, an elastic rope, an L-shaped strip, a first water outlet pipe, and a second ring, the T-shaped tube is pulled to rotate around the circular tube, thereby realizing the adjustment of the spraying angle of the spray head, which can expand the atomization range and improve the atomization and dust reduction efficiency of the device. In the present invention, by providing a cleaning mechanism, a cylinder, a third rotating rod, a brush, a slide bar, a connecting rod, and a small brush, the slide bar slides from the inside to the outside in the groove of the brush, thereby driving the small brush to rotate and clean the dust in the gaps of the screen mesh. When the third rotating rod slides along the screen mesh, the brush contacts the four convex blocks on the screen mesh and shakes. At this time, the third rotating rod extends outward from the cylinder and stretches the spring.

[0016] The water storage mechanism 9 includes a water bucket 901. On one side of the water bucket 901 close to the water pump 10, a second water outlet pipe 902 is fixedly connected.

On the inner wall of the top of the water bucket 901, a water inlet cylinder 905 is fixedly connected. Two water outlet holes 906 are formed on the side surface of the water inlet cylinder 905.

At the bottom of the water inlet cylinder 905, a hole of the same size as the small square block 908 is formed. The water inlet cylinder 905 is slidably connected to the small square block 908. When the water pump 10 works, an external water source enters the water bucket 901 from the water inlet pipe 909. The filter screen 903 can filter impurities to prevent the spray head 204 from being blocked. When the water level reaches a certain height, the hollow ball 904 moves upward due to the buoyancy force, squeezing the small square block 908 to move upward until the sealing plug 907 blocks the connection port between the water inlet cylinder 905 and the water inlet pipe 909, thereby stopping pumping water and realizing automatic control of the water volume in the water bucket 901.

[0017] Working principle: During operation, an external motor drives the first rotating rod 102 and the second rotating rod 103 to rotate. The large fan blade 104 and the small fan blade 105 rotate simultaneously to draw air, increasing the wind force to atomize the sprayed water. The atomization direction of the device can be adjusted 360 degrees by manually rotating the large turntable 5. At the same time, the hydraulic rod 7 can adjust the angle of the device up and down, facilitating operation, thereby expanding the scope of atomization and dust reduction. When the hydraulic rod 7 extends, it deflects around the small turntable 6, causing the small turntable 6 to rotate and pull the L-shaped long strip 208. The first ring 205 is forced to reciprocate within the ring buckle 203, causing the ring buckle 203 to drive the T-shaped pipe 202 to rotate around the circular pipe 201, thereby realizing the adjustment of the spraying angle of the spray head 204, expanding the atomization range, and improving the atomization and dust reduction efficiency of the device. When the cylinder 301 rotates with the first rotating rod 102, the third rotating rod 302 drives the brush 303 to perform a circular motion to clean the dust on the screen 107. During the rotation of the brush 303, the slide bar 304 slides from the inside to the outside in the groove of the brush 303, thereby driving the small brush 306 to rotate and clean the dust in the gaps of the screen 107. When the third rotating rod 302 slides along the screen 107, the brush 303 contacts and shakes the four convex blocks 108 on the screen 107. At this time, the third rotating rod 302 extends outward from the cylinder 301 and stretches the spring. When the brush 303 separates from the convex block 108, the third rotating rod 302 is reset under the action of the spring to pull the brush 303 to strike and clean the screen 107, shaking off the dust attached to the screen 107 after cleaning, preventing dust accumulation, and improving the cleaning efficiency. When the water pump 10 is working, the external water source enters the water bucket 901 from the water inlet pipe 909. The filter net 903 can filter impurities to prevent the water spray head 204 from being blocked. When the water level reaches a certain height, the hollow ball 904 moves upward due to the buoyancy force, squeezing the small square 908 to move upward until the sealing plug 907 blocks the connection port between the water inlet cylinder 905 and the water inlet pipe 909, thereby stopping the water pumping and realizing the automatic control of the water volume in the water bucket 901.
