[0016] Compared with the prior art, the dust removal device provided by the present application at least has the following beneficial effects:

[0017] The dust removal device provided by the embodiment comprises a shell, an air circulation device, a turbulent flow generator, a dust collection assembly and a detection assembly. The shell is provided with an air inlet end and an air outlet end. The air circulation device is arranged at the air outlet end. The air circulation device comprises an air compressor. The air circulation device can drive air flow, so that the air flows into the air compressor and the air inlet of a vacuum cleaner. The air compressor increases the flow speed of air molecules and can adjust the air pressure according to actual use requirements to adjust the air flow rate. The turbulent flow generator is arranged at the air inlet end. The turbulent flow generator comprises a plurality of trapezoidal blades. When the air circulation device is started, dust-containing air enters the shell from the air inlet end through the turbulent flow generator. The turbulent flow generator can increase the instability and turbulent intensity of gas flow, helping dust particles to better contact the filtering surface of the filter screen, thereby improving the dust removal efficiency. The dust collection assembly is arranged between the air circulation device and the turbulent flow generator. The detection assembly is arranged between the turbulent flow generator and the dust collection assembly. The air entering the shell passes through the detection assembly and the dust collection assembly in sequence and then enters the air compressor and the air inlet of the vacuum cleaner. Finally, the air is discharged from the air outlet of the air compressor and the vacuum cleaner. The dust collection assembly comprises a plurality of dust collection containers and a plurality of vertically arranged filter screens. Along the direction from the air inlet end to the air outlet end, the mesh size of the plurality of filter screens decreases in sequence. The filter screens correspond to the dust collection containers one by one. The dust collection containers are located at the bottom of the corresponding filter screens. The bottom of each dust collection container is provided with a weighing member. In this way, when the dust-containing air passes through the plurality of filter screens, each filter screen can block dust particles larger than the mesh size of the filter screen. Dust particles smaller than the mesh size of the filter screen can smoothly pass through the filter screen. Dust particles larger than the mesh size of the filter screen will fall into the dust collection container or be blocked in the mesh. The filter screen and the dust collection container realize the concentration and collection of dust particles larger than the mesh size of the filter screen. The weighing member can weigh the dust particles in the dust collection container and on the filter screen. During the air flow in the shell, the detection assembly comprises a mass spectrometer, a differential pressure sensor and a speed sensor. The data processing module is electrically connected with the mass spectrometer, the differential pressure sensor and the speed sensor. Therefore, the mass spectrometer, the differential pressure sensor and the speed sensor detect the passing air respectively. The mass spectrometer is used to detect the chemical composition of the collected dust-containing air. The differential pressure sensor is used to detect the gas pressure difference between the positions close to the air inlet end and the air outlet end in the shell. The data processing module receives the gas pressure difference data transmitted by the differential pressure sensor in real time, realizes the real-time monitoring of the gas pressure difference in the shell, indirectly judges the dust accumulation degree of the filter screen, timely cleans the filter screen and prevents the filter screen from being blocked or the efficiency from being reduced. When the filter screen is blocked, the air flow speed in the shell will also be reduced. Therefore, the speed sensor is used to detect the wind speed of the dust-containing air in the embodiment. The main function of the speed sensor is to monitor the wind speed in the air duct or the environment in real time. Combined with the monitoring data of the differential pressure sensor, the speed sensor realizes the monitoring of whether the dust removal device works smoothly, ensuring the dust removal effect.Further, the data processing module is connected with the mass spectrometer, the differential pressure sensor and the speed sensor, the data processing module is connected with all the weighing members, the data processing module can collect and process the data collected by the mass spectrometer, the differential pressure sensor, the speed sensor and all the weighing members to obtain the parameters of the air containing dust. Among them, the multiple filter screens filter dust of different particle sizes, the weighing members can weigh and measure dust of different particle sizes, and the data processing module can arrange and calculate the measurement results of the multiple weighing members to obtain the content ratio of dust of different particle sizes.

[0018] The dust removal device provided by the embodiment can filter and purify the air containing dust. In addition, in the process of removing dust from the air, the mass spectrometer, the differential pressure sensor and the speed sensor in the detection assembly are used to detect the air, the dust particles in the air can be detected, the chemical composition of the air containing dust is obtained, the weighing members of the dust collection assembly and the data processing module can measure the amount and proportion of dust of different particle sizes, the detection of dust in the air is realized, the function of the dust removal device is increased, and the application range of the dust removal device is expanded.
