[0044] Preferably, Figure 6-Figure 11 As shown, it also includes a sand removal fan 8, which is arranged on the air outlet of the sand removal channel 7 to discharge the particulate pollutants in the sand removal channel 7. In this embodiment, the sand removal fan 8 adopts a single-inlet centrifugal fan, and the air inlet of the sand removal fan 8 is connected to the air outlet of the sand removal channel 7, and the particulate pollutants in the sand removal channel 7 are extracted by pressurization and can be transported to a designated area. In this embodiment, the number of the sand removal fan 8 is at least one.

[0045] Preferably, Figure 9-11As shown, there are two sand-discharging fans 8, and the air outlets of the sand-discharging channel 7 are set to two. The two sand-discharging fans 8 are respectively arranged on the air outlets of the two sand-discharging channels 7, and a check valve 6 is installed in the middle of the sand-discharging channel 7. In this embodiment, one of the two sand-discharging fans 8 is a main fan, and the other is a standby fan. The two sand-discharging fans 8 realize the function of one for use and one for standby, ensure the stable operation of the sand-discharging operation, and avoid the problem of affecting the sand-discharging when only one sand-discharging fan 8 fails to work continuously. The purpose of setting the check valve 6 is that when one of the sand-discharging fans 8 is working to pump sand, the check valve 6 closes the other air outlet of the sand-discharging channel 7 to prevent the air containing particulate pollutants from flowing back from the air outlet to the sand-discharging channel 7.

[0046] Preferably, in the present embodiment, the number of the sand discharge fans 8 is two, the air outlet of the sand discharge channel 7 is set to two, the two sand discharge fans 8 are respectively arranged on the air outlets of the two sand discharge channels 7, and a partition plate (the partition plate is not drawn) is installed in the sand discharge channel 7, the partition plate divides the sand discharge channel 7 into two independent spaces, and the two independent spaces are both connected to the sand collecting trough 3. In the present embodiment, the two sand discharge fans 8 are both main fans, and the two sand discharge fans 8 work at the same time to jointly extract the particulate pollutants in the sand discharge channel 7. The purpose of setting two sand discharge fans 8 is that when the width dimension of the frame 1 is too large, the length of the sand discharge channel 7 is too large, and only relying on one sand discharge fan 8 cannot meet the sand discharge demand, so two sand discharge fans 8 are set to pump sand at the same time. The purpose of setting the partition plate is to form two independent spaces in the sand discharge channel 7 to avoid the problem of mutual interference when the two sand discharge fans 8 are pumping sand at the same time.

[0047] The particle pollutant filtering and purification unit involved in the utility model has the following working principle:

[0048] First, the operator Figure 1-Figure 11 , and the description of the above components to install each component;

[0050] Then, if Figure 4 , Figure 5As shown, the air containing particulate pollutants passes through the ventilation port 1020 and enters the air inlet of the filter blade 2. The air changes its original direction of movement and passes through the air inlet channel of the filter blade 2. The particulate pollutants rely on inertial movement to reach the sand collecting trough 3 along the original direction of movement, and fall into the sand discharge channel 7 after colliding with the sand collecting trough 3.

[0051] Then, the operator starts the sand removal fan 8, which generates suction to extract the particulate pollutants in the sand removal channel 7 and transport them to a designated area for discharge.

[0052] Preferably, after long-term use, when too many particulate pollutants accumulate on the filter blades 2 and affect the filtering effect, the blade cover 4 is opened, and then the filter blades 2 are pulled out from the top plate slot from bottom to top, and then put back into the frame 1 after cleaning, or the filter blades 2 that have been cleaned in advance are put back into the frame 1 to achieve the cyclic replacement of the filter blades 2. The filter blades 2 can be replaced uniformly, or one or several can be replaced; for example, there are three filter blades 2 in this application, and the three filter blades 2 can be replaced at the same time, or only one or several can be replaced.

[0053] The utility model relates to a particle pollutant filtering and purifying unit, which is provided with a frame 1, in which filter blades 2 are detachably arranged. When too much particle pollutant is accumulated on the filter blades 2, the filter blades 2 can be removed from the frame 1 for cleaning, and the cleaned filter blades 2 can be put back into the frame 1, thereby solving the problem of the need for regular replacement and serious waste caused by the use of disposable physical filters in the prior art.

[0054] The particle pollutant filtering and purification unit involved in the utility model can filter, separate, collect and remove particulate pollutants in the air such as dust, sand, powder, salt mist, etc., and discharge them to the outdoors through the sand exhaust fan 8. The overall structure does not require daily maintenance or regular replacement of parts, and has a wide range of applications.
