Air particle collecting device and support device thereof

Abstract

The invention relates to an air particle collecting device and a support device thereof. The air particle collecting device comprises a cyclone separator, a cylindrical collector and an air pump, wherein the cyclone separator is provided with a nozzle and an air inlet, and the cylindrical collector is provided with an air outlet and contains liquid. The cyclone separator is connected with the collector, and the air pump is connected with the air outlet or the air inlet. Detected air enters the cyclone separator through the air inlet under the effect of the air pump and then is sprayed to the collector through the nozzle, forms rotational air flow in the collector and then is discharged out of the air outlet. Particles in air are adsorbed to the circumferential wall of the collector or adsorbed by liquid under the effect of the rotational air flow. The support device comprises a base, a clamping support, a supporting rod and a hanging rod. The base is provided with a structure for fixing the collector and a supporting foot capable of adjusting levelness of the base. The hanging rod can be connected with different hanging insertion parts so as to install the devices at different sites. The air particle collecting device is simple in structure and convenient to use, the range of collecting the various particles in the air is wide, and particle escape is less.

Description

technical field [0001] The invention relates to a device for collecting particles and microorganisms existing in the air, in particular to an air particle collecting device and a support device thereof. Background technique [0002] The collection of particles and microorganisms (hereinafter referred to as particulates) present in the air and the identification and counting of the collected particulates are important in many fields such as pharmaceutical industry, agriculture, food industry, medical environment, health services, veterinary services , site monitoring, etc., the size of the particles to be collected can vary from 0.3um to tens of microns. At present, the devices for collecting particles in the air are mainly divided into inertial impact collection devices, centrifugal collection devices and liquid collection devices in principle.

Problems solved by technology

At present, the devices for collecting particles in the air are mainly divided into inertial impact collection devices, centrifugal collection devices and liquid collection devices in principle. This kind of high-speed impact makes the particles in the air adhere to the solid plate, but the disadvantage of this device is that some particles are rebounded by the solid plate greater than the adsorption force of the solid plate to these particles, and then escape back into the air. The lower solid plate will not be able to adsorb these particles, and it will not be able to collect these particles; the centrifugal collection device is to make the particles in the air obtain a certain The centrifugal force breaks away from the airflow and adheres to the inner wall of the cylindrical container, but the disadvantage of this device is that when the diameter of the particle is relatively small (less than a few microns), the particle cannot obtain enough centrifugal force to make it break away from the airflow and adhere to the container Therefore, these small-diameter particles cannot be collected; the liquid collection device refers to the high-speed air entering the liquid, and the liquid collects the particles in the air, but the disadvantage of this device is that the air enters the liquid. Many bubbles will be generated , and the particles that have been collected in the liquid will leave the liquid with these bubbles and escape into the air, and the liquid will also be consumed faster as the bubbles leave

[0003] The traditional support for installing the air particle collection device is generally connected by its own box and connecting rods. This installation method has a complex structure, high manufacturing and processing costs for the box, and a small scope of application. venue unavailable
