[0025] The utility model discloses to solve the problem that the filter screen is blocked by impurities after sample filtration in pretreatment device, and the filtering effect is poor if not cleaned in time, which causes deviation of detection result and reduces the accuracy of detection, and provides a 5-amino levulinic acid content accurate detection instrument as shown in the figure Figs. 1-3 The sample needs to be appropriately pretreated before detection, and the 5-amino levulinic acid content detection result of the pretreated sample is more accurate.

[0026] In the utility model, the top of the pretreatment tank 1 is provided with a top cover 2, the top surface of the top cover 2 is provided with a material conveying pipe 4 and a feeding pipe 41, the end of the feeding pipe 41 penetrates through the top cover 2 and is communicated inside the filter screen frame 23, and the end of the material conveying pipe 4 penetrates through the top cover 2 and is communicated between the processing cavity 11 and the outer wall of the filter screen frame 23.

[0027] It should be noted that the pretreated sample is conveyed into subsequent chromatographic column and other devices by a high-pressure pump and other devices to complete subsequent detection, which is all prior art and not shown in the figure and will not be described here.

[0028] In the utility model, the top surface of the top cover 2 is fixedly connected with a motor 24, the top end of the rotating rod 21 penetrates through the top cover 2 and is fixedly connected with the rotating shaft of the motor 24.

[0029] The sample is placed inside the processing cavity 11 of the pretreatment tank 1, the rotating rod 21 is rotated, the rotating rod 21 drives the stirring blade 22 to rotate, the stirring blade 22 stirs and mixes the sample, ensures that the 5-amino levulinic acid in the sample is more uniform, reduces the detection error caused by uneven concentration, and the stirring can also promote the chemical reaction between the sample and the detection reagent, so that the reaction is more sufficient and fast.

[0030] The stirring of the sample by the stirring blade 22 can eliminate the bubbles and precipitates in the sample and improve the detection conditions.

[0031] As the rotating rod 21 rotates, the filter frame 23 on it also rotates. The filter frame 23 filters the sample, and impurities in the sample are intercepted inside the filter frame 23, avoiding deviations in the detection results due to interference from impurities and improving the accuracy of the detection.

[0032] Furthermore, fixed rods 3 are fixedly connected to both sides of the processing chamber 11, and brush bristles 31 are fixedly connected to one end of the two fixed rods 3 close to each other. The brush bristles 31 are in movable contact with the outer wall of the filter frame 23. During the process of rotating the filter frame 23 for filtration, the brush bristles 31 brush the outer wall of the filter frame 23, so that the brush bristles 31 can remove impurities on the filter frame 23 in time, prevent impurities from clogging the filter frame 23, and thus maintain the permeability of the filter frame 23.

[0033] Because the outer wall of the filter frame 23 is cleaned during its rotation, an automated cleaning effect is achieved, reducing manual intervention and lowering the labor intensity and work risks for workers.

[0034] In this invention, after stirring, the filter frame 23 is pulled up. As the filter frame 23 moves upward, it can break up the air bubbles in the liquid. By lifting the filter frame 23, the air bubbles and tiny particles can be removed, thereby avoiding interference with the test results. This helps to reduce errors caused by incomplete filtration and improve the accuracy of the test results.

[0035] It should be noted that the filter frame 23 is installed to the bottom of the rotating rod 21 via a flange or other mounting parts, which facilitates the replacement or maintenance of the filter frame 23. The specific mounting parts are not limited. Flanges or other mounting parts are existing technologies and are not shown in the figure, so they will not be described in detail here.

[0036] In this utility model, the bottom surface of the top cover 2 is fixedly connected with a plurality of plug rods 25 in a ring shape. The plug rods 25 are inserted into the insertion holes on the top surface of the pretreatment tank 1. The plug rods 25 serve as limiters. A handle for lifting can be installed on the top of the top cover 2. The handle is existing technology and is not shown in the figure. It will not be described in detail here. By pulling the handle upward, the filter frame 23 can be pulled out, which facilitates the maintenance and cleaning of the filter frame 23.

[0037] In this invention, a heating wire 5 is installed inside the pretreatment tank 1. The heating wire 5 helps to heat the inside of the treatment chamber 11, so that the sample is heated to a certain temperature, which can reduce the viscosity of the liquid and enhance its fluidity, making it easier to pass through the filter frame 23. Heating can also promote the dissolution or dispersion of certain components in the liquid, which helps to reduce the risk of clogging the filter frame 23.

[0038] It should be noted that the processing cavity 11 can be provided with a temperature detection device for monitoring the temperature of the liquid in the processing cavity 11, ensuring that the heating wire 5 heats the sample to a specified temperature. The temperature detection device is a mature technology in the prior art, and is not shown in the figure and will not be described here.

[0039] It should also be noted that the top of the filter screen frame 23 is spaced apart from the bottom surface of the top cover 2. The spacing between the filter screen frame 23 and the top cover 2 ensures the normal operation of the device.
