Description

Technical Field

[0001] This utility model relates to the field of particle size analyzer technology, specifically to a particle size analyzer aerosol drainage protection device. Background Technology

[0002] A particle size analyzer is an instrument that uses physical methods to test the size and distribution of solid particles. Based on different testing principles, it can be divided into sedimentation particle size analyzers, sedimentation balances, laser particle size analyzers, optical particle counters, resistance particle counters, particle image analyzers, etc.

[0003] Laser particle size analyzers infer particle size by analyzing the scattering characteristics of laser light by particles and analyzing the angle and intensity distribution of scattered light. However, laser particle size analyzers require protective devices to prevent the aerosol from being contaminated or adhering to the lens during testing. However, currently common aerosol protection devices only prevent the aerosol from flowing towards the lens by guiding it. However, once the diffused aerosol enters the inner wall of the lens through the joint gap, it will affect the overall performance of the device.

[0004] There is an urgent need for a particle size analyzer aerosol drainage protection device to solve the technical defects mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a particle size analyzer aerosol drainage and protection device to solve the problem of aerosol entering the lens mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a particle size analyzer aerosol drainage protection device, comprising a first connecting pipe, a connecting pipe movably connected to the left side of the first connecting pipe, a second connecting pipe installed at the top of the first connecting pipe, a third connecting pipe provided at the top of the second connecting pipe, a telescopic pipe installed between the third connecting pipe and the second connecting pipe, a protective cover installed at the top of the third connecting pipe, an aerosol nozzle installed at the output end of the third connecting pipe, the aerosol nozzle installed inside the protective cover, a fitting ring fixedly connected to the right side of the protective cover, an exhaust port provided on the left side of the protective cover, a sealing ring installed inside the protective cover, a connecting slider fixedly connected to the top and bottom of the sealing ring, a connecting groove provided inside the protective cover, a telescopic rod provided on the left side of the telescopic pipe, a locking bolt installed on the telescopic rod, a connecting plate fixedly connected to the left side of the second connecting pipe, and a fixing plate fixedly connected to the left side of the third connecting pipe.

[0007] As a further technical solution of this utility model, the aerosol nozzle is provided in two sets, and the spray direction of the aerosol nozzle is towards the exhaust port.

[0008] As a further technical solution of this utility model, the protective cover covers the outside of the detection lens of the particle size analyzer, and the sealing ring is tightly fitted with the outer ring of the detection lens of the particle size analyzer.

[0009] As a further technical solution of this utility model, a pull rod is fixedly connected to the connecting slider, and the connecting slider is embedded inside the connecting groove.

[0010] As a further technical solution of this utility model, the top end of the telescopic rod is connected to the fixed plate, and the bottom end of the telescopic rod is connected to the connecting plate.

[0011] As a further technical solution of this utility model, the inner side of the connecting pipe is provided with an internal thread, and a reinforcing ring is movably connected to the left side of the connecting pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the particle size analyzer aerosol drainage protection device not only realizes the function of preventing aerosol from entering the lens and the function of easy adjustment of the protection height, but also realizes the function of easy connection and use;

[0013] The particle size analyzer is equipped with an aerosol nozzle, a bonding ring, a sealing ring, a protective cover, an exhaust port, a connecting slider, and a connecting groove. The protective cover is placed over the particle size analyzer's detection lens. The sealing ring can fit tightly against the outer ring of the detection lens. The aerosol is delivered into the interior of the protective cover through the first, second, and third connecting pipes. The aerosol is evenly sprayed out from the aerosol nozzle and moves towards the exhaust port. The detection lens can detect the particles in the aerosol. During the detection process, the sealing ring always seals and protects the gaps at the lens connection, preventing aerosol from entering the lens and damaging the particle size analyzer. The sealing ring can be removed and replaced from inside the protective cover. This structure facilitates stable protection and reduces the occurrence of aerosol entering the lens.

[0014] The structure is equipped with a second connecting pipe, a telescopic pipe, a third connecting pipe, a fixing plate, locking bolts, a telescopic rod, and a connecting plate. The distance between the second and third connecting pipes can be adjusted through the telescopic pipe. When it is necessary to extend the height of the pipeline, the locking bolts on the telescopic rod can be unscrewed first, and then the telescopic pipe can be pulled upward. The telescopic pipe will move the protective cover to a suitable position, and then the locking bolts can be installed on the telescopic rod to achieve a fixed lock. This structure realizes the function of easy adjustment of the protective height.

[0015] By incorporating a connecting pipe, a first connecting pipe, a second connecting pipe, and a reinforcing ring, the connecting pipe needs to be connected to the aerosol conveying equipment before aerosol diversion. The connecting pipe is connected to the aerosol discharge pipe by screwing it on. After connection, the reinforcing ring can be rotated to make the pipe connection more secure and sealed, preventing aerosol from being discharged from the pipe connection. This structure achieves the function of easy connection and use. Attached Figure Description
