Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

The fan dust removal mechanism shown in Figure 1 includes a volute 1, the volute 1 is provided with an air outlet 3 and an air inlet 2, and the air inlet 2 is provided with an elbow 4 with an upward opening, and the elbow 4 passes through the volute 1 Bolt connection, easy to disassemble and clean, the opening of the elbow 4 is provided with a filter cover 5, the filter cover 5 is snap-connected with the elbow 4, the filter cover 5 is provided with a plurality of air holes, and the air outlet 3 is provided with a spray 8, the spray port 8 is connected with a catheter, and the catheter goes deep into the water tank 7, and the water tank 7 is connected to the volute 1 on the side of the air outlet 3, and the water tank 7 is also provided with a pump for absorbing liquid. Aspirator, the air inlet 2 is provided with a dust sensor, when the dust concentration reaches the set value, the dust sensor controls the aspirator to be energized through the PCL, the aspirator supplies liquid to the catheter, and the spray port sprays water mist to remove dust , PLC is a programmable controller. Described filter cover 5 is coated with arc-resistant paint, and described aspirator is a small electric pump, and it is connected with power supply through electric wire and dust sensor.

As shown in Figure 1, the application is provided with an elbow 4 with an opening facing upwards at the air inlet, and a filter cover 5 is installed on the elbow 4, which can effectively avoid inhaling the dust on the surface of the ground and the dust with larger particles At this time, the airflow inhaled into the volute 1 will only bring the particles floating in the air smaller than the pore diameter of the filter cover 5 into the air inlet 2, and the dust sensor will detect the concentration of suspended dust in the air inlet 2. When suspended in the air inlet 2 When the dust concentration in the water is enough, the dust sensor transmits the signal to the PCL, and the PCL controls the aspirator in the spray port 8 to work, and the aspirator sucks water into the catheter, and the water in the catheter is sprayed through the spray nozzle 8. out, the water by the spray head 8 can become elegant water mist. The extremely fine mist particles are conducive to the wetting and trapping of fine dust, and can wrap and settle the blown dust. Considering that this application is mostly used in working environments with a lot of dust particles, this application coats the filter cover 5 with arc-resistant paint, which has a certain fire and explosion-proof function, and can avoid the collision and friction of solid particles and filter cover to a certain extent. Afterwards, ignition occurs, which causes dust explosion and reduces potential safety hazards.

The working principle of the dust sensor is that particles and molecules will produce light scattering phenomenon under the irradiation of light, and at the same time absorb part of the energy of the irradiated light. When a beam of parallel monochromatic light is incident on the measured particle field, it will be affected by scattering and absorption around the particle, and the light intensity will be attenuated. In this way, the relative attenuation rate of the incident light passing through the concentration field to be measured can be obtained. The size of the relative attenuation rate can basically linearly reflect the relative concentration of dust in the field to be measured.

It should be understood that the above descriptions are only specific embodiments of the present utility model and are not intended to limit the present invention. For the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
