RU46147U1 - DEVICE FOR CATCHING SMALL OBJECTS FROM AIR - Google Patents

Abstract

The present invention is intended for the absorption of small insects, flying pollen, spores of fungi or other dust particles from the air and can be used to monitor air pollution by dust particles. The invention is a compact device that allows you to capture small objects without the use of electricity for pumping air samples. The essence of the invention is as follows. The device consists of a transparent tube with means for creating an air flow placed in it along the axis, a filter system worn on the lower end of the tube with the possibility of replacement, consisting of a conical chamber, coaxially placed at its narrow end with the possibility of axial movement of the air intake tube and filter material, fixed at the wide end of the conical chamber. A device is provided for mounting the device in a suspended state, for example, in the form of a hook fixed to the upper end of a transparent tube. The means for creating air flow in a transparent tube is, for example, bent along a strip of tin or other heat-sensitive material and painted black. As a filter material, you can use a piece of mill gas.

Description

The device is designed for the absorption of small insects, flying pollen, spores of fungi or other dusty particles from the air. and can be used to monitor air pollution by dust particles.

Known trap for insects is a tube on one end of which is fixed a rubber bulb, and on the other there are teeth. However, this trap cannot be used without human intervention and is intended only for capturing insects [1].

A device for collecting air samples is known, comprising a transparent tube filled with a coated medium, a filter system consisting of an inlet chamber, an adsorption layer for removing airborne contaminants, and an outlet, and a pump for pumping air samples [2]. This device can only be used if there is electricity.

The objective of the invention is to provide a compact device for capturing small objects from the air to monitor the air around us. The technical result consists in the fact that its application does not require the use of electricity for pumping air samples.

The problem is solved in that the device for collecting small objects from the air consists of a transparent tube with means for creating an air flow placed in it along the axis, a filter system worn on the lower end of the tube with the possibility of replacement and consisting of a conical chamber coaxially placed in it narrow end with the possibility of axial movement of the intake pipe and filter material fixed to the wide end of the conical chamber. The device is equipped with a device for mounting it in

suspended, for example in the form of a hook, mounted at the upper end of the transparent tube.

The means for creating air flow in a transparent tube is, for example, bent along a strip of tin or other heat-sensitive material and painted black. As a filter material, you can use a piece of mill gas.

The figure shows a General view of the device.

The device consists of a transparent tube 1, placed in it along the axis of the means for creating an air flow, for example, strips of painted sheet 2, a conical chamber 3, an intake pipe 4, filter material 5 and a hook 6 for hanging the device fixed to the tube 1 with a spoke 7.

The device operates as follows. The device with a hook is mounted in suspension in the required place. When sunlight hits the strip of tin 2, the latter heats up and creates an upward flow of air in tube 1. Thus, all objects located near the intake pipe 4 fall inside the conical chamber 3 and will settle on the filter material 5 or accumulate inside the conical chamber. For the device, it is preferable to use a transparent tube 1 m long and 70 mm in diameter (in a case tested in practice). If the design is increased in size, then the need for sunlight will not be so great, as there will be a "draft", so that the collection can be carried out around the clock.
