Automatic dustproof system and method for separation chamber

Abstract

The invention discloses an automatic dustproof system for a separation chamber. The automatic dustproof system comprises gas pressure sensors mounted inside and outside the separation chamber of a color selector respectively, a control module, a gas source switch and a high-pressure gas storage tank, wherein the gas pressure sensors are all connected with the control module; the control module is connected with the gas source switch; the gas source switch is positioned in the cavity body of the separation chamber of the color selector and connected to the high-pressure gas storage tank through a pipeline. The invention further discloses an automatic dustproof method for the separation chamber. According to the method, the gas pressure in the cavity body of the separation chamber is controlled to keep the normal-pressure state of the cavity body of the separation chamber all the time so as to prevent dust and powder from entering the separation chamber. The automatic dustproof system and method have the advantages that the passive seal is changed to active seal, so that the situation of instable color selection effect caused by influence of the dust on a camera signal is prevented; the manual maintenance is not required; the running is full-automatic; a gas source of the color selector can be directly used, so that the cost increment is very low but a very good effect is achieved; the application prospect in the field of color selectors is wide.

Description

technical field [0001] The invention relates to the field of color sorters, in particular to a dust-proof system and method for a sorting chamber of the color sorter. Background technique [0002] As an important part of the color sorter, the sorting room contains key electrical components such as light sources, lenses, and cameras, providing original signals for the effective identification of the color sorter. Due to the relatively high concentration of dust and dust in the work site of the color sorter, dust and dust can easily enter the sorting room and adhere to the surface of optical devices such as lenses and sensors when working for a long time, directly affecting the quality of the original signal, thereby affecting The working effect of the color sorter. [0003] At present, the color sorters on the market mainly prevent dust from entering the sorting chamber by means of sealing, but machining errors, assembly errors, sealing strip materials, sealing methods, etc....

Problems solved by technology

Due to the relatively high concentration of dust and dust in the work site of the color sorter, dust and dust can easily enter the sorting room and adhere to the surface of optical devices such as lenses and sensors when working for a long time, directly affecting the quality of the original signal, thereby affecting Working effect of color sorter

[0003] At present, the color sorters on the market mainly prevent dust from entering the sorting chamber by means of sealing, but machining errors, assembly errors, sealing strip materials, sealing methods, etc. will all affect the actual dust-proof effect, and with time Accumulated mechanical structure deformation, aging of sealing strips, etc. will also reduce the sealing effect, and the dust-proof of the sorting room cannot be effectively achieved for a long time
