[0025] Referring to Figure 1 As shown in the utility model embodiment, in some embodiments, the air lock 5 is connected to the stirring wheel housing 2, in this embodiment, dust generated by grinding enters first dust collector 4 along the direction of arrow A, the part of dust with greater mass settles to the bottom of first dust collector 4, enters stirring wheel housing 2 through air lock 5, facilitates dust discharge.
[0026] Referring to Figure 1 And Figure 2 As shown in the utility model embodiment, in some embodiments, the stirring wheel housing 2 is equipped with stirring wheel housing partition 10 near one side of the air lock 5, in this embodiment, stirring wheel housing 2 is equipped with stirring wheel housing partition 10, blocks the wind force generated by negative pressure fan 7, avoids dust discharged by air lock 5 from entering dust collection system again through first air pipe 3, improves dust collection efficiency.
[0027] Referring to Figure 1 As shown in the utility model embodiment, in some embodiments, the stirring wheel housing partition 10 is located between the air lock 5 and the first air pipe 3, in this embodiment, dust collection and discharge are carried out respectively, reduce external interference, improve efficiency.
[0028] Referring to Figure 1As shown, in some embodiments, the first air pipe 3 is located on one side of the stirring wheel housing partition 10 close to the pulverizer 1, and the air lock 5 is located on the other side of the stirring wheel housing partition 10 away from the pulverizer 1. The first air pipe 3 is close to the pulverizer 1, which facilitates the collection of dust in time when the crushed feed is discharged, shortens the dust removal distance, and reduces the generation of dust.
[0029] Referring to Figure 1 As shown, in some embodiments, the first dust collector 4 is a cyclone dust collector. In the present embodiment, the cyclone dust collector separates particulate matter and dust in the air by utilizing the principle of centrifugal force and inertial separation. The cyclone dust collector includes structures such as an air inlet, a cyclone pipe, an exhaust pipe, and a dust collection barrel. When the gas containing particulate matter and dust enters the cyclone dust collector, the gas forms a rotating flow in the cyclone pipe. Due to the action of centrifugal force, the particulate matter and dust are thrown to the pipe wall and fall along the pipe wall, and finally are collected in the dust collection barrel, while the purified gas is discharged from the exhaust pipe, thereby improving the dust removal efficiency.
[0030] Referring to Figure 1 As shown, in some embodiments, the first dust collector 4 is connected with a negative pressure fan 7 through a second air pipe 8. In the present embodiment, the negative pressure fan 7 is used to generate a reverse airflow of dust by means of atmospheric pressure, so as to suck the dust into the dust collector for filtration, which can further improve the dust removal efficiency. Under the action of the wind force, the small-particle feed after crushing flows out at a faster speed, the feeding speed is accelerated, and the crushing efficiency is improved by more than 30%.

The dust that is not completely filtered by the first dust collector 4 can be further filtered, the dust removal efficiency is improved, and the dust removal effect is ensured.
[0032] Referring to Figure 1 As shown, in some embodiments, the second dust collector 9 is a bag dust collector. In the present embodiment, the bag dust collector is a filtering type dust removal equipment based on the filtering principle, which filters the dust in the gas by using organic or inorganic fiber filter cloth. The dust-containing gas enters the middle box from the air inlet, enters the bag from the outside of the filter bag, and the dust is blocked on the surface of the filter bag outside. The purified air enters the bag, and then enters the upper box from the upper part of the bag. Finally, the purified air is discharged from the exhaust pipe, thereby further improving the dust removal efficiency.
