[0028] The sealing device comprises a sealing support fixedly connected with the liquid cup 12, a storage hole provided with a rotary storage disc below the liquid cup 12, and a sealing filter mechanism movably arranged in the storage hole. A push rod motor is arranged below the sealing filter mechanism, and the sealing filter mechanism, the push rod motor and the rotary storage disc are electrically connected with a controller.

[0029] The sealing filter mechanism comprises a filter disc, a sample placing cup and a vacuum adsorption disc from top to bottom. A vacuum pipe is arranged on the side of the vacuum adsorption disc, and the vacuum pipe is connected to a vacuum pump through an electromagnetic valve.

[0030] The filter disc is used for fixing a filter membrane, filtering a sample, obtaining insoluble substances for subsequent processing and analysis. The sample placing cup is used for waste liquid diversion. A sand core is arranged in the sample placing cup. The vacuum adsorption disc is used for vacuum filtration. The vacuum adsorption disc is arranged below the sample placing cup. A vacuum pipe is arranged on the side of the vacuum adsorption disc, and the vacuum pipe is connected to a waste liquid device. A lower boss is movably connected with the sealing device. The lower boss is sealed with the filter disc under the extrusion of the push rod motor, and then the electromagnetic valve is opened. Under the action of the vacuum pump, the vacuum adsorption disc starts to perform vacuum treatment on the sealed structure.

[0035] The liquid inlet device is specifically that the solution bottle is connected to the peristaltic pump through a catheter and is connected to the rapid heating device.

[0036] The rapid heating device includes a heating device, a temperature sensor and a liquid level sensor. The rapid heating device is arranged on the catheter pipeline from the peristaltic pump to the liquid cup 12.

The probe of the temperature sensor is closely attached to the outer surface of the pipeline.

[0037] The solution is pumped into the pipeline through the peristaltic pump. After the liquid level sensor obtains the liquid level information in the pipeline, the controller transmits an opening signal to the heating device to heat and warm the solution in the pipeline, and the two heating devices are used for preliminary heating and secondary warming. After the temperature sensor attached to the outer wall of the pipeline monitors that the temperature reaches a temperature threshold, the information is transmitted to the controller, the controller transmits a signal to the sealing device and the peristaltic pump, the sealing device is completed after sealing, and the peristaltic pump is opened. The output catheter of the heating device is arranged above the liquid cup 12 through the catheter mounting hole.

According to the different characteristics of the solution, the frequency and power of the ultrasonic generator 11 are adjusted, and the solution is better treated. The ultrasonic generator is controlled by the control unit, the higher the frequency and the greater the power of the ultrasonic generator, the greater the corresponding energy, and the faster the dissolution and mixing rate.
