Specifically, as shown in fig. 1, the dust purification apparatus 5 includes a purifier 507, an intake duct 504, and an exhaust duct 508. The purifier 507 can remove dust and purify the dust-containing gas. One end of the air inlet pipe 504 is connected to the inside of the purifier 507 in an openable manner, the other end of the air inlet pipe 504 is communicated with the dust removal port 201 of the mixer 2 through the dust collection cover 501, and the dust collection cover 501 is communicated with the air outlet of the material detection device 4.

The material detection device 4 can collect real-time material mixing effect data so as to feed back and adjust the operation parameters of the mixer 2. The exhaust pipe 508 communicates with the purifier 507, thereby discharging the purified gas to the outside of the apparatus. The inside of clarifier 507 is equipped with negative pressure and produces the mechanism, and negative pressure produces the mechanism and can produce the negative pressure in clarifier 507 to make the interior negative pressure environment that forms of inlet channel 504, inlet channel 504 utilizes the negative pressure effect to extract the gas that blendor 2 and material detection device 4 discharged respectively to collect gas in dust cage 501, in order to make gas more concentrated get into inlet channel 504, improve gas purification efficiency and the comprehensive nature of gas purification.

The first port and the second port are respectively penetrated through the side surface of the purifier 507, and the second port is positioned below the first port. The first pipeline is communicated with the first port, and the second pipeline is communicated with the second port. The first conduit is in communication to direct the gas in the inlet conduit 504 to an upper position within the scrubber 507 via an indirect route and through the top of the scrubber 507 to the outlet conduit 508 via an outlet. The second conduit can introduce the gas in the gas inlet conduit 504 to a position lower in the purifier 507 in a communicated state. The arrangement of the structure enables the gas entering the purifier 507 through the first pipeline and the second pipeline to be distinguished in the inner cavity of the purifier 507, so that only the purification mechanism in the purifier 507 needs to be reasonably arranged, for example, the purification mechanism is arranged in the middle of the purifier 507, the gas can pass through the purification mechanism from bottom to top in the purifier 507 to be subjected to dust removal and purification, and the filtered dust can fall to the bottom of the purifier 507 under the action of self weight.

In order to rationally plan the connection structure between the first duct and the exhaust duct 508, as shown in fig. 2, the first port preferably penetrates the exhaust duct 508, that is, the gas in the first duct can directly enter the exhaust duct 508 from the first port, so that the gas flow efficiency is increased, the number of penetrating ports in the purifier 507 is reduced, and the airtightness of the purifier 507 is improved.
It can be understood that the first and second conduits are each fitted with a temperature sensor therein. For example, a first temperature sensor 510 is installed in the first pipeline, a second temperature sensor 511 is installed in the second pipeline, and the first temperature sensor 510 and the second temperature sensor 511 can monitor the gas temperatures in the first pipeline and the second pipeline respectively, so that when the gas temperatures reach a preset temperature, the on-off states of the first pipeline and the second pipeline can be changed as required to change the operation state of the device 5.
