TECHNICAL FIELD

[0001] The utility model relates to dustproof device technical field, especially a dustproof device for building material mixing. BACKGROUND

[0002] In modern urban construction, building material mixing operation is an indispensable link. However, the dust pollution problem produced in this process is increasingly serious, not only affecting the air quality of the construction site, but also posing a potential threat to the health of construction personnel. In order to effectively deal with this problem, the dustproof device for building material mixing emerges as the times require. The dustproof device for building material mixing is a kind of equipment specially designed to reduce dust emission in the process of building material mixing. It sets up dustproof mechanism around or inside the mixing operation area, uses water mist or other media to adsorb and settle dust in the air, so as to effectively reduce the diffusion and pollution of dust.

[0003] Construction sites usually use fog gun machine to carry out dust reduction operation. The fog gun machine is internally provided with a fan, which generates strong wind by high-speed rotation, blows water mist to the operation area, and achieves the effect of dust reduction. However, the fan is installed inside the fog gun machine, which brings many inconveniences to the maintenance and repair of the equipment. Once the fan fails, the whole fog gun machine needs to be disassembled for inspection and repair, which not only consumes time and effort, but also may affect the construction progress.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. When dust control is required during the mixing of building materials, the base box can be moved to the usage position, and the water pump can be turned on to draw water from the tank into the annular spray head and spray it out, forming water mist at one end of the cone. At this time, the fan can be turned on to blow air to one side of the cone, which can blow the water mist to the vicinity of the mixer, so that dust in the air can combine with the water mist and fall to the ground, thus enabling dust control during the mixing of building materials.

Two symmetrically arranged clamping plates 16 are fixedly connected to the side of the pressure plate 15 away from the threaded post 14. Both clamping plates 16 are engaged with the rotating cylinder 8.

[0019] As an optional technical solution of this utility model, a water tank 17 is fixedly connected to the inner wall of the bottom box 1, and a water pump 18 is fixedly connected to the top of the water tank 17. The output end of the water pump 18 is connected to the annular spray head 12 through a hose, and the input end of the water pump 18 is connected to the water tank 17 through a pipe. When the water pump 18 is turned on, the water inside the water tank 17 is pumped into the annular spray head 12 and sprayed out, which can form a water mist at one end of the conical cylinder 11.

[0020] As an optional technical solution of this utility model, a limiting pin 19 is fixedly connected to the bottom surface of each L-shaped bracket 7, and two symmetrically arranged arc-shaped slots 20 are opened on the top surface of the top plate 2. The two limiting pins 19 are slidably connected to the top plate 2 through the two arc-shaped slots 20. When the L-shaped bracket 7 rotates, it will drive the limiting pins 19 to slide inside the arc-shaped slots 20, which can limit the rotation range of the L-shaped bracket 7.

[0021] As an optional technical solution of this utility model, a rotating hole 21 is provided through one side of the conical cylinder 11. The conical cylinder 11 is rotatably connected to the crossbar 10 through the rotating hole 21. Pushing the conical cylinder 11 to rotate around the crossbar 10 can quickly release the blockage of the conical cylinder 11 on the fan 81, so as to facilitate the maintenance of the fan 81.

[0022] As an optional technical solution of this utility model, the output end of the fan 81 corresponds to the conical cylinder 11, and a protective net 22 is fixedly connected to the inner wall of the rotating cylinder 8, which corresponds to the fan 81.

[0023] As an optional technical solution of this utility model, the side of the pressure plate 15 away from the card plate 16 is fixedly connected to two symmetrically arranged guide rods 23, and the threaded column 14 is located between the two guide rods 23.

The two locking plates 16 are engaged with the rotating cylinder 8 through the two slots 24. The threaded column 14 is twisted to make it rotate relative to the rotating frame 13. Through the threaded transmission, the pressure plate 15 can be driven away from the conical cylinder 11 until the locking plate 8 moves completely out of the slot 24, and then the locking of the conical cylinder 11 can be released.

[0025] A dust control device for mixing building materials operates on the following principle: 1) When dust control is required during the mixing of building materials, the bottom box 1 can be moved to the working position, and the water pump 18 can be turned on to draw water from the water tank 17 into the annular spray head 12 and spray it out. Water mist can be formed at one end of the cone 11. At this time, the fan 81 can be turned on to blow air to one side of the cone 11, which can blow the water mist to the vicinity of the mixer. This can cause dust in the air to combine with the water mist and fall to the ground, thus enabling dust control during the mixing of building materials.

[0026] 2): Activate the hydraulic cylinder 9 to drive the rotating cylinder 8 to rotate between the two L-shaped supports 7, and activate the motor 5 to drive the second gear 6 to rotate. Through meshing transmission, the rotating seat 3 can be rotated, and the orientation of the conical cylinder 11 can be adjusted in multiple directions.

[0027] 3) When maintenance work is required on the fan 81, the operator can twist the threaded column 14 to make it rotate relative to the rotating frame 13. Through the threaded transmission, the pressure plate 15 can be driven away from the conical cylinder 11 until the clamping plate 8 is completely moved out of the clamping slot 24. Then the locking of the conical cylinder 11 can be released. Then push the conical cylinder 11 to make it rotate around the crossbar 10, which can quickly release the blockage of the conical cylinder 11 on the fan 81.

[0028] In summary, this dust control device for mixing building materials allows for dust control operations during material mixing. The base box 1 can be moved to the operating position, and the water pump 18 can be turned on to draw water from the water tank 17 into the annular spray head 12 and spray it out, forming a water mist at one end of the conical cylinder 11. At this time, the fan 81 can be turned on to blow air towards one side of the conical cylinder 11, blowing the water mist towards the vicinity of the mixer. This allows airborne dust to combine with the water mist and fall to the ground, enabling dust control operations during material mixing. Furthermore, the hydraulic cylinder 9 can be activated to drive the rotating cylinder 8 to rotate between the two L-shaped supports 7, and the motor 5 can be turned on. This causes the second gear 6 to rotate, and through meshing transmission, the rotating seat 3 can rotate, allowing for multi-directional adjustment of the orientation of the conical cylinder 11. When maintenance is required on the fan 81, the operator can twist the threaded column 14 to rotate it relative to the rotating frame 13. Through threaded transmission, the pressure plate 15 can be moved away from the conical cylinder 11 until the clamping plate 8 completely moves out of the clamping slot 24, releasing the lock on the conical cylinder 11. Then, the conical cylinder 11 can be pushed to rotate around the crossbar 10, quickly releasing the blockage of the conical cylinder 11 on the fan 81, facilitating maintenance of the fan 81.
