Problems solved by technology

[0003] With the continuous advancement of science and technology, the management of clean workshops is becoming more and more stringent, but the dust particle counters in our country have not had an accurate and stable testing device, so that the dust particle counters in our country cannot develop healthily, and this situation is very important for clean workshops. The excellent rate of the quality of the products will be greatly affected, which will increase the elongation cost of the manufacturing enterprise and will improve the relative competitiveness of the enterprise. This situation seriously affects the development of our manufacturing enterprise.

Abstract

The invention relates to a dust granule counter which comprises an operation table top, a mixer, a PSL (photostimulated luminescence) sprayer, a sprayer flow meter, an air flow meter, a prefilter, a high-efficiency filter, a flow dispensing grid plate, a fluorescent lamp, an air pressure regulating valve, a spray pressure regulating valve, a sampling buffer and a compressed air inlet, wherein the mixer, the sprayer flow meter and the air flow meter are arranged on the operation table top; the high-efficiency filter is positioned on the flow dispensing grid plate; the sampling buffer is also arranged on the operation table top; the prefilter is arranged on the mixer; and the flow dispensing grid plate is arranged on the fluorescent lamp.

Description

【Technical field】 [0001] The invention relates to a dust particle counter, in particular to a dust particle counter for testing the cleanliness of the environment. 【Background technique】 [0002] In the prior art, a dust particle counter (hereinafter referred to as a calibration device) is a highly targeted testing device. It uses polystyrene standard particle diluent (PSL) as the spray carrier, and emits stable polystyrene solid pellets, which are mainly suitable for the calibration of dust particle counters. It has the characteristics of reasonable structure and process, strong operability and convenient use. In order to ensure that the calibration process is not disturbed by the outside air, the operation process is all placed in a class 100 clean environment. [0003] With the continuous advancement of science and technology, the management of clean workshops is becoming more and more stringent, but the dust particle counters in our country have not had an accurate and...
