Description

Technical Field

[0002] Laser particle size analyzer is an instrument for measuring and analyzing the abundance of physical particles. It is divided into wet test instruments, dry test instruments, and wet-dry integrated test instruments according to the dispersion system. Its principle is that when light is propagating, the wavefront is restricted by gaps or particles with the same wavelength scale. The emission of each elementary wave at the restricted wavefront interferes in space to produce diffraction and scattering. The spatial (angular) distribution of diffracted and scattered light energy is related to the wavelength of the light wave and the scale of the gaps or particles. The recovery device of the laser particle size analyzer can recycle some particles, which is convenient for the staff to measure the recovered particles using the laser particle size analyzer.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will combine the accompanying drawings of the embodiments of the present utility model Figure 1-6 , and clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present utility model.

[0030] As Figure 1-6 shown: A laser particle size analyzer includes the main body 101 of the laser particle size analyzer. A screening box 102 is provided on one side of the main body 101 of the laser particle size analyzer. The screening box 102 is provided so that the various components therein can be supported, and the material particles can be screened therein. The screening box 102 is connected to one side of the main body 101 of the laser particle size analyzer by bolts, so that it is convenient for disassembly and assembly. A plurality of screening mechanisms are provided on the inner side wall of the screening box 102. The plurality of screening mechanisms are provided so that the material particles can be subjected to multi-stage screening therein, and the material particles with different particle sizes can be screened and collected separately. Each screening mechanism includes a first support plate 103 provided on one inner wall side of the screening box 102. The first support plate 103 is welded to the vertical inner wall on one side of the screening box 102. A second support plate 104 is provided on the other inner wall of the screening box 102. The second support plate 104 is welded to the vertical inner wall on the other side of the screening box 102. The first support plate 103 and the second support plate 104 are provided so that the sliding groove 105 opened thereon can support the sliding block 106 and the fixed frame 107, thereby making the support structure more stable.

[0031] The first support plate 103 needs to be set higher than the second support plate 104, so that the sliding groove 105 formed thereon can be inclined. The sliding grooves 105 are inclined on both the first support plate 103 and the second support plate 104. The inclination of the sliding groove 105 enables the sliding block 106 and the fixed frame 107 provided thereon to also be inclined, and thus inclined towards the second support plate 104. Therefore, the screening effect of the material particles can be improved, and the accumulation of materials can be avoided, preventing the material particles from being difficult to screen. Each sliding groove 105 on the first support plate 103 and the second support plate 104 can be integrally formed by die casting during manufacturing, making its connection structure more stable. The inner side walls of the sliding groove 105 on the first support plate 103 and the sliding groove 105 on the second support plate 104 need to be arranged in parallel, so as to prevent the sliding block 106 from getting stuck during reciprocating movement. The two sliding grooves 105 are both slidably connected with a sliding block 106, enabling the sliding block 106 to reciprocate in the corresponding sliding groove 105, thereby improving the screening effect. A fixed frame 107 is arranged between the two sliding blocks 106. The setting of the fixed frame 107 enables the components thereon to be supported. The two sides of the fixed frame 107 are welded to one side of the corresponding sliding block 106, making its connection structure more stable.

[0032] A screening plate 108 is arranged on the inner side wall of the fixed frame 107. The setting of the screening plate 108 enables the material to be screened on the screening plate 108. The screening plate 108 is connected to the inner side wall of the fixed frame 107 by bolts, making the screening plate 108 easy to disassemble and assemble. Thus, when the screening plate 108 needs to be cleaned, it is convenient to disassemble and assemble. Multiple screening holes are formed on the screening plate 108. The setting of multiple screening holes enables the small particle material particles to fall through them, while the large particles stay on the screening plate 108 and slide into the storage box 202 for collection. The multiple screening holes and the screening plate 108 can be integrally formed by die casting during manufacturing, making its connection structure more stable. A material blocking frame 109 is arranged above the screening plate 108. The setting of the material blocking frame 109 can prevent the material particles from falling off when the fixed frame 107 reciprocates. The material blocking frame 109 is welded to the upper part of the screening plate 108, making its connection structure more stable. Guide plates 110 are symmetrically arranged on the side of the material blocking frame 109 facing the second support plate 104. The setting of the guide plates 110 enables the screened material particles to be guided into the storage box 202 for collection.

[0033] The material guiding plate 110 is welded to one side of the blocking frame, so that its connection structure is more stable. A reciprocating motor 111 is arranged on the outer side wall of the screening box 102 and at the position corresponding to the fixed frame 107. The output shaft of the reciprocating motor 111 is fixedly connected to the vertical surface on one side of the fixed frame 107. The reciprocating motor 111 is arranged so that its output shaft makes a reciprocating movement, thereby driving the fixed frame 107 and various components thereon to make a reciprocating movement, and further enabling the material particles to obtain a reciprocating vibration force on the screening plate 108. Therefore, the screening effect of the material particles can be improved, and the situation of poor screening effect caused by their accumulation can be avoided. An L-shaped support frame 112 is arranged on one side of the reciprocating motor 111. The L-shaped support frame 112 is arranged so that the reciprocating motor 111 can be supported, and the reciprocating motor 111 can be prevented from moving due to the movement of the output shaft of the reciprocating motor 111. The reciprocating motor 111 is connected to the L-shaped support frame 112 by bolts, so that the reciprocating motor 111 is convenient for disassembly and assembly. One end of the L-shaped support frame 112 is connected to the outer side wall of the screening box 102 by bolts, so that it can be supported and is convenient for disassembly and assembly.
