Description

Technical Field

[0001] This utility model relates to the field of sample window installation technology, and more specifically, to a split plug-in structure suitable for switching between dry and wet sample windows in a laser particle size analyzer. Background Technology

[0002] Currently, the dry and wet sample windows of desktop dry and wet laser particle size analyzers are installed inside the instrument. This means that during dry testing, the sample ejected from the sample channel easily adheres to the wet glass sample window, requiring frequent cleaning. While the dry and wet sample windows are automatically switched by a lead screw motor, this method, although intelligent, lacks precision and can sometimes affect the instrument's stability. Specifically, particles from dry testing may stick to the lead screw, causing motor malfunction and, in severe cases, motor damage, thus interrupting the switching between dry and wet modes. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0024] like Figure 1 As shown, a split plug-in structure suitable for switching between dry and wet sample windows in a laser particle size analyzer includes a combined dry and wet laser particle size analyzer. The analyzer includes a main unit and a sample window 1, as well as a cover plate 2, a mounting base 3, a plug-in handle 4, a ceramic elbow 5, a flange 6, piping (not shown in the figure), a fixing plate 7, a feed nozzle 8, a sample window ejection core 9, and a limiting assembly.

[0025] The fixed base 3 and the plug-in handle 4 are both fixed on the cover plate 2, and the two are located below and above the cover plate 2, respectively.

[0026] The ceramic elbow 5 is mounted on the fixed base 3, and one end of the ceramic elbow 5 is connected to the sample window spray core 9, while the other end of the ceramic elbow 5 is connected to a pipeline through the flange 6.

[0027] The fixed plate 7 and the cover plate 2 are connected by a fixed block (the fixed block is not numbered in the figure), and the fixed plate 7 is provided with a feed nozzle 8 that is connected to the pipeline;

[0028] Sample window 1 is connected to sample window injection core 9;

[0029] Limiting components are respectively installed on the main unit and the fixed base 3 to improve the precision of the fit between the dry sample window 1 and the main unit.

[0030] Specific implementation of the embodiments of this utility model, such as Figure 1 As shown, the limiting assembly includes a guide rail and a track wheel 10.

[0031] Several track wheels 10 are fixed on the fixed base 3;

[0032] The main unit is equipped with a guide rail (not shown in the figure) that mates with the track wheel 10.

[0033] To reduce the amount of sample ejected outside sample window 1 due to impact, further optimizations to the above-described embodiments are made, such as... Figure 1 As shown, a conical guide cover 11 is provided between the sample window 1 and the sample window spray core 9.

[0034] The working process of this utility model:

[0035] During testing, the sample enters through the inlet 8 via the sample window 1, then passes through the pipe and flange 6 to the ceramic elbow 5 for impact dispersion. The sample is then ejected from the sample window spray core 9 and finally enters the dust collection channel through the sample window 1 to complete the test. The device uses the pull-in handle 4 to assemble and disassemble the dry / wet sample window. The track wheels and the guide rails inside the main unit achieve a precise fit, making the insertion and removal easier and more accurate.

[0036] In addition, this application re-optimizes the structure of sample window 1, increases the diameter of the internal channel of sample window 1, and adds a conical guide structure to the upper part of sample window 1, thereby reducing the probability of the sample being ejected outside sample window 1 due to impact, that is, effectively reducing the amount of ejected sample.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
