At present, the determination process generally relies on traditional laboratory methods, which requires operators to manually complete a series of independent and tedious steps, including sample heating, filtering, washing, drying, cooling and constant weight measurement. There are significant defects in the prior art: first, the filtering relying on natural gravity and the slow heating drying to prevent explosive boiling result in a very long time consumption of the whole process, which seriously restricts the detection efficiency and cannot meet the quality control requirements of modern industry for high throughput and rapid response.

DETAILED DESCRIPTION

[0027] Attached Figures 1-6 It is the best embodiment of the multifunctional rapid insoluble matter determination device, the utility model is further explained in detail below, the above-mentioned drawings are all structure schematic diagrams of neglecting connecting pipeline.

[0028] The multifunctional rapid insoluble matter determination device includes box 1, still includes the sample preparation device 2, sample processing device 3, sample moving device 4 and control unit 5 arranged in the box 1. The sample preparation device 2 includes the solution bottle 21, peristaltic pump 22 and waste liquid treatment device 23 arranged on one side of the fixed plate in the lower layer of the box 1, still includes the rapid heating device 24, ultrasonic treatment device 26 and sealing device 25 arranged in the upper layer of the box 1. The sample processing device 3 includes drying device 31 and weighing device 32 arranged in the upper layer of the box 1. The sample moving device 4 includes X-axis displacement mechanism 41, Y-axis displacement mechanism 42, Z-axis displacement mechanism 43 and movable clamping jaw 44. The control unit 5 is arranged on the other side of the fixed plate in the lower layer of the box 1. The sample preparation device 2, sample processing device 3 and sample moving device 4 are electrically connected with control unit 5.

[0029] The sample preparation device 2 is that the solution bottle 21 is connected to the rapid heating device 24 through the peristaltic pump 22, the pipeline connected to the output end of the rapid heating device 24 is arranged above the liquid cup through the pipeline mounting rack, the ultrasonic treatment device 26 is arranged in the liquid cup, and the sealing device 25 is arranged below the liquid cup. The waste liquid discharge port in the sealing device 25 is connected to the waste liquid treatment device 23 through a pipeline.

[0030] The solution bottle 21 is one or more, and the specific number is determined according to the solution to be analyzed. In the embodiment, two groups of solution bottles 21 are arranged, and two groups of peristaltic pumps 22 are arranged correspondingly. The solution bottle 21 is connected to the rapid heating device 24 through the conduit by means of the peristaltic pump 22.

[0031] The rapid heating device 24 comprises a heating device, a temperature sensor and a liquid level sensor. The rapid heating device 24 is arranged on the conduit pipeline from the peristaltic pump 22 to the liquid cup. The temperature sensor is arranged on the outer side of the pipeline between the heating device and the liquid level sensor. The heating device is two groups, and the two heating devices are arranged adjacently. The heating device is a hollow barrel structure in particular, and a spiral electric heating wire is arranged in the interlayer between the outer wall and the inner wall. The inner diameter of the hollow inside of the heating device is slightly larger than the outer diameter of the pipeline, and the pipeline is inserted into the hollow inside of the heating device during use. The upper end and the lower end of the heating device are both provided with threads at the top, so as to facilitate the fixation of the heating device.

[0032] The probe of the temperature sensor is closely attached to the outer surface of the pipeline, and high-temperature-resistant adhesive tape is arranged on the combined periphery of the temperature sensor and the pipeline to fix the temperature sensor. The temperature sensor is arranged between the liquid level sensor and the heating device, and is used for detecting the temperature of the solution in the current pipeline. The temperature sensor obtains the temperature of the current pipeline and feeds back data information to the controller to form a control closed loop, so as to judge whether the temperature threshold is reached. If the threshold is reached, the peristaltic pump 22 is started to inject the heated solution into the liquid cup.

[0033] The liquid level sensor is a "concave" structure, and the groove is matched with the pipeline and is fixed on the pipeline through the limiting structure of the liquid level sensor. The liquid level sensor comprises a first liquid level sensor and a second liquid level sensor, which are arranged on the pipelines connected to the upper end and the lower end of the heating device respectively. The first liquid level sensor and the second liquid level sensor are a certain distance away from the heating device, and are used for monitoring whether there is solution in the current pipeline. It is used to prevent dry burning caused by the absence of solution in the pipeline in the heating state, thereby preventing damage to the equipment.

[0034] The liquid cup is made of corrosion-resistant and heat-conducting material, and the outer surface of the liquid cup is provided with heat preservation electric heating wire. When the solution is pumped into the liquid cup under the action of the peristaltic pump 22, the controller transmits an opening signal to open the heat preservation electric heating wire, which is used for heat preservation of the solution in the liquid cup.

[0035] The solution is pumped into the pipeline by the peristaltic pump 22. When the first and second liquid level sensors obtain the liquid level information in the pipeline, the information is transmitted to the controller, and the controller transmits an opening signal to the heating device to heat the solution in the pipeline. The solution is heated by the two heating devices to accelerate the heating rate. When the temperature sensor attached to the pipeline arm detects that the temperature reaches the temperature threshold, the information is transmitted to the controller, and the controller transmits an opening signal to the sealing device 25 and the peristaltic pump 22. After the sealing device 25 is opened to seal, the peristaltic pump 22 is opened to pump the heated solution into the liquid cup. The heat preservation wire outside the liquid cup is turned on to heat the solution.

The vacuum adsorption disc is provided with a vacuum tube on the side surface.

[0037] The filter disc is used to fix the filter membrane and filter the sample to obtain insoluble substances for subsequent processing and analysis. The filter disc comprises, from outside to inside, an annular base, a filter membrane and an annular compression ring. The outer diameter of the annular compression ring is slightly smaller than the inner diameter of the annular base, and the annular compression ring is embedded in the inner cavity of the annular base and covers the filter membrane.

The top edge of the sample placing cup has an annular boss with a radius slightly larger than the middle part. The middle part is an annular structure with an outer diameter larger than the sample hole diameter of the filter disc. The bottom part is an annular surface with a radius slightly smaller than the middle part. The sample placing cup is provided with a sand core. The sand core in the sample placing cup is used to prevent the insoluble substances in the filter disc from dripping liquid during subsequent processing such as weighing, causing pollution of the device.

[0039] The vacuum adsorption disc is used for vacuum filtration. The vacuum adsorption disc is arranged below the filter disc and has a cylindrical structure with a conical hole in the inside. A waste liquid discharge port connected to the outer wall is arranged at the top of the conical hole, and the waste liquid discharge port is connected with a vacuum tube. The middle part of the conical hole is provided with a sealing structure, and the diameter of this area is slightly larger than the diameter of the bottom part of the sample placing cup. A silica gel pad is arranged at the connection between the vacuum adsorption disc and the sample placing cup to seal and prevent leakage by extrusion and the action of the silica gel pad. The waste liquid and waste gas enter the vacuum adsorption disc through the sand core of the sample placing cup and are discharged through the waste liquid discharge port.

[0040] The rotating placement disc is used for placing the filter disc and the sample cup, and comprises a placement disc provided with a plurality of placement holes, a rotating shaft fixedly connected to the center of the placement disc and connected to a rotating motor.

[0043] Therefore, when the controller drives the push rod motor 323 to move upward, the push rod motor 323 drives the vacuum adsorption disc fixedly connected to the top to move upward. The vacuum adsorption disc contacts the sample cup and the filter disc during the upward movement, drives the two to move upward until they stop against the liquid cup. The sealing is realized through the structural design and the extrusion effect of the push rod motor 323.
