Description

Technical Field

[0001] The utility model relates to the technical field of aggregate production, in particular to a spray device for suppressing dust in aggregate production. Background Art

[0002] During aggregate production, the shipping workshop contains high dust content, which will have serious impacts on health and production. Long-term exposure to high-concentration dust environment will aggravate the development of respiratory diseases. At the same time, when spraying to suppress dust, too many nozzles will lead to high water consumption, resulting in a waste of water resources. Utility Model Content

[0003] The problem solved by the utility model is to provide a spray device for suppressing dust in aggregate production, which solves the technical problem that the dust content in the shipping workshop during aggregate production is relatively high, which has a serious impact on health and production. Long-term exposure to a high-concentration dust environment will aggravate the development of respiratory diseases. At the same time, when spraying to suppress dust, an excessive number of nozzles leads to a large amount of water consumption, resulting in a waste of water resources.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A spray device for suppressing dust in aggregate production, comprising a high-pressure fine mist dust suppression humidifier and a spray mechanism, wherein the high-pressure fine mist dust suppression humidifier comprises a high-pressure plunger pump, the high-pressure plunger pump is connected to a plurality of spray mechanisms through a connecting pipe and a high-pressure shunt valve, and a filter is installed on the connecting pipe;

[0006] The spray mechanism comprises a delivery pipe, and a plurality of support pipes are rotatably mounted on the bottom side of the delivery pipe, and the support pipes are connected to the top side of one end of the rotating pipe, and an atomizing nozzle is mounted on the bottom side of the other end of the rotating pipe.

[0007] Preferably, the spacing between adjacent support tubes is twice the length of the rotating tube, and the length of the rotating tube is the same as the spray radius of the atomizing nozzle.

[0008] Preferably, the support pipe and the delivery pipe are connected via a rotary joint.

[0009] Preferably, a mounting plate is installed on the side wall of the conveying pipe, a motor is installed on the mounting plate, and a first sprocket is installed on the output end of the motor.

[0010] Preferably, a second sprocket is sleeved on the outer side of the support tube, and a plurality of the second sprockets are connected to the first sprocket via a chain transmission.

[0011] The beneficial effects of the utility model are as follows: water is atomized by the cooperation of the high-pressure micro-mist dust suppression humidifier and the spray mechanism. When the water mist particles are of the same size as the dust particles, the water mist particles and the dust particles are easily aggregated into agglomerates, begin to settle under the action of gravity, and then fall to the ground, completing the dust suppression effect and ensuring a good working environment.

[0012] During spraying, the motor drives the first sprocket to rotate, which in turn drives the second sprocket to rotate through chain transmission, thereby driving the support tube to rotate, thereby realizing the rotation of the rotating tube and the atomizing nozzle. The rotating atomizing nozzle increases the range of atomizing spray, reduces the number of atomizing nozzles, and saves water. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Specific examples are given below.

[0021] See also Figure 1 to Figure 4 A spraying device for suppressing dust in aggregate production, comprising a high-pressure fine mist dust suppression humidifier 1 and a spraying mechanism 2, wherein the high-pressure fine mist dust suppression humidifier 1 comprises a high-pressure plunger pump, which is connected to a plurality of spraying mechanisms 2 through a connecting pipe and a high-pressure shunt valve, and a filter is installed on the connecting pipe;

[0022] The spray mechanism 2 includes a delivery pipe 3, and a plurality of support pipes 4 are rotatably mounted on the bottom side of the delivery pipe 3. The support pipe 4 is connected to the top side of one end of a rotating pipe 5, and an atomizing nozzle 6 is mounted on the bottom side of the other end of the rotating pipe 5.

[0023] The spacing between adjacent support tubes 4 is twice the length of the rotating tube 5. The length of the rotating tube 5 is the same as the spray radius of the atomizing nozzle 6, ensuring that there will be no dead corners for spray atomization dust suppression and no overlapping areas for spray atomization dust suppression during the rotary spraying process, thus saving water.

[0024] The support tube 4 and the delivery tube 3 are connected through a rotating joint 7. A mounting plate is installed on the side wall of the delivery tube 3, and a motor 8 is installed on the mounting plate. A first sprocket 9 is installed on the output end of the motor 8. A second sprocket 10 is mounted on the outer side of the support tube 4. Several second sprockets 10 are connected to the first sprocket 9 through a chain 11 transmission. The first sprocket 9 is driven to rotate by the motor 8, and the second sprocket 10 is driven to rotate through the chain 11 transmission, thereby driving the support tube 4 to rotate, thereby realizing the rotation of the rotating tube 5 and the atomizing nozzle 6.

[0025] The high-pressure micro-mist dust suppression humidifier 1 uses a high-pressure plunger pump to increase the water pressure to 4-7Mpa, and then transports the pressurized water to the spray mechanism 2 through a connecting pipe and a high-pressure shunt valve, and atomizes it through the atomizing nozzle 6 of the spray mechanism 2 to produce micro-mist particles with a diameter of ≤10μm. Water is sprayed out from the atomizing nozzle 6 in the form of micro-mist under the action of high pressure. When the water mist particles are of the same size as the dust particles, the water mist particles and the dust particles are easy to aggregate into agglomerates, begin to settle under the action of gravity, and then fall to the ground.
