[0002] A laser particle size analyzer is an instrument for measuring and analyzing the abundance of physical particles. It has a wide measurement range and good repeatability. This instrument is suitable for samples in various forms, such as powders, emulsions, and suspensions, and is widely used in materials science, pharmaceuticals, chemicals, and environmental protection.

[0003] While laser particle size analyzer technology is becoming increasingly mature, it still has certain drawbacks in practical use. During actual use, the laser particle size analyzer is affected by environmental humidity and temperature. When the ambient humidity is high and the temperature is high, the detection accuracy of the laser particle size analyzer will vary.

[0004] Therefore, a catalyst laser particle size analyzer was designed to solve the above problems. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0018] The following describes, with reference to the accompanying drawings, some embodiments of a catalyst laser particle size analyzer provided by this utility model.

[0019] Example 1: Combination Figures 1 to 5 As shown, the present invention provides a catalyst laser particle size analyzer, including a protective component 100, a particle size analyzer 300 installed inside the protective component 100, and two fans 200 installed on the protective component 100. The protective component 100 is used to provide an effective protective space for the particle size analyzer 300, and the fans 200, in conjunction with the protective component 100, are used to provide a low-humidity and low-temperature operating environment for the particle size analyzer 300.

[0020] The protective assembly 100 includes a protective shell 110. A first cover plate 1101 is fixedly installed at one end of the protective shell 110, and a second cover plate 1102 is fixedly installed at the other end of the protective shell 110. Two fans 200 are respectively fixedly installed inside the first cover plate 1101 and the second cover plate 1102. A horizontal shaft 120 is movably installed inside the first cover plate 1101 and the second cover plate 1102. An upper cover 130 is installed outside the horizontal shaft 120. A filter element 1301 is fixedly installed inside the upper cover 130. Four sets of symmetrically distributed limiting plates 140 are fixedly installed inside the protective shell 110. A first top pad 1502 is movably installed inside two sets of limiting plates 140, and a second top pad 170 is movably installed inside the other two sets of limiting plates 140. A top clamping plate 1701 is on the second top pad 170. The particle size analyzer 300 is installed on the upper surface of the first top pad 1502 and the second top pad 170; Both the first top pad 1502 and the second top pad 170 are made of stainless steel inner plate and rubber outer sleeve, and the top of the first top pad 1502 and the second top pad 170 are rough surfaces, and a rubber pad is fixedly installed on the inner side of the upper cover 130.

[0021] When the particle size analyzer 300 is needed, the upper cover 130 is flipped outward with the filter element 1301 as the axis. Then, the particle size analyzer 300 is placed on top of the first top pad 1502 and the second top pad 170. Then, the upper cover 130 is reset until the particle size analyzer 300 is in a sealed environment. Then, the two fans 200 are run until the two fans 200 dehumidify and control the temperature of the operating environment of the particle size analyzer 300. The sealed environment after temperature control and dehumidification will not interfere with the detection of the particle size analyzer 300.

[0022] Example 2: Combination Figures 2 to 5 As shown, in the above embodiment, a first bottom pad 150 and a second bottom pad 160 are fixedly installed on the bottom of the inner side of the protective shell 110. Two springs 1501 are fixedly installed on the top of the first bottom pad 150, and the top of the springs 1501 is fixedly installed on the top of the first top pad 1502. The top of the second base pad 160 is fixedly installed with a positioning plate 1601, a bottom clamping plate 1602 and a fixing plate 1901. A horizontally placed double-acting screw 190 is movably installed in the positioning plate 1601 and the fixing plate 1901. A slide 1802 is installed on the external thread of the double-acting screw 190. Symmetrically distributed traction plates 1801 are movably installed at both ends of the slide 1802. A suspension 180 is movably installed in the bottom clamping plate 1602, and the other ends of the two traction plates 1801 are movably installed in the suspension 180. The first cover plate 1101 has a transverse hole inside, and the rod segment of the bidirectional lead screw 190 is movably installed in the transverse hole.

[0023] Preferably, the outer surface of the protective housing 110 is provided with a rubber pad layer. When the particle size analyzer 300 is placed on top of the first top pad 1502 and the second top pad 170, the reset upper cover 130 will seal and press the top of the protective housing 110 tightly. The two running fans 200 can effectively dehumidify the environment around the particle size analyzer 300 and create a temperature-controlled airflow around the particle size analyzer 300 to prevent data abnormalities from occurring around the particle size analyzer 300. The rod segment of the bidirectional lead screw 190 can be installed in the first cover plate 1101 via bearings.

[0024] The working principle and usage process of this utility model are as follows: First, the upper cover 130 is flipped outward with the horizontal axis 120 as the axis until the upper ports of the protective shell 110, the first cover plate 1101 and the second cover plate 1102 are exposed. Then, the particle size analyzer 300 is placed along the upper ports of the protective shell 110, the first cover plate 1101 and the second cover plate 1102 until the bottom of the particle size analyzer 300 is fixed on the top of the first top pad 1502 and the second top pad 170. When the particle size analyzer 300 needs to be activated, according to the height requirement of the particle size analyzer 300 in the inner cavity of the protective component 100, the wheel at the outer end of the bidirectional lead screw 190 is pre-rotated until the slide 1802 moves laterally along the threaded section of the bidirectional lead screw 190. As the slide 1802 moves laterally toward the fixed plate 1901, the slide 1802 will push the outer ends of the two traction plates 1801 to flip upwards until the top of the suspension 180 pushes the top clamping plate 1701 and the second top pad 170 to lift upwards. Finally, the second top pad 170 and the first top pad 1502 will lift the particle size analyzer 300 according to the height adjustment requirement. When the particle size analyzer 300 is in use, the upper cover 130 is reset around the horizontal axis 120 until the particle size analyzer 300 is in a sealed environment. The two running fans 200 will remove the moisture in the sealed environment to ensure that the particle size analyzer 300 is not disturbed by the moisture in the environment during operation, and at the same time provide a low temperature and dry environment for the operating area of ​​the particle size analyzer 300.

[0025] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
