Description

Technical Field

[0001] The present invention relates to the field of dust detection, and particularly to a dust detection device and a dust detection method for cement kiln production. Background Art

[0002] Dust detection refers to the process of measuring and analyzing the dust concentration in the air through specific instruments and methods. This is very important in fields such as industrial production, environmental protection, and labor hygiene, because dust not only affects air quality but may also cause harm to human health, such as triggering pneumoconiosis and the like.

[0003] There are various dust concentration detectors on the market now. Classified by measurement principle, they include: weighing method dust detectors, laser dust detectors, electrostatic dust detectors, etc. The working principles of dust detectors are mainly based on light absorption, light scattering, β-ray, and alternating current electrostatic induction principles. At present, the main dust monitoring methods include filter weighing method, X-ray diffraction method, scattered light method, piezoelectric balance method, β-ray dust measurement method, and light penetration method, etc. The weight method is the most common method for dust measurement.

[0004] During the production process of cement kilns, a large amount of dust is generated, and dust detection needs to be carried out frequently.

[0005] Chinese Patent Application CN113405371A discloses a dust collection device for high-temperature calcination kilns, including a housing. A heat insulation layer is arranged inside the housing, and the heat insulation layer is enclosed inside the housing by a heat-resistant layer. The cross-section of the heat-resistant layer is a serrated step. The serrated step includes a dust-containing surface and a transition surface. The dust-containing surface can accommodate dust, so that part of the dust forms a buffer layer on the dust-containing surface during the falling process; the dust-containing surface is horizontal or inclined upward; the transition surface connects the dust-containing surface to eliminate the safety hazards brought to workers by high-temperature materials during discharging.

[0006] Chinese Patent Application CN115900363A discloses an on-line dust removal device for kilns, including a kiln body and a dust collector. A plurality of branched air pipes extending downward are formed on the bottom plate of the kiln body. The bottom discharge port of the branched air pipe communicates with the first feed port of the heat exchanger through a first pipe body. The first discharge port of the heat exchanger communicates with the feed port of the dust collector through a second pipe body. The upper air outlet of the dust collector communicates with the second feed port of the heat exchanger through a main connecting pipe; it can discharge the dust in the kiln with the protective gas from the kiln for heat exchange and filter it. While realizing the treatment of dust, its gas can be recycled, and during the process of gas circulation, it blows air on the inner side wall of the branched air pipe to reduce or prevent the dust in the gas from adhering to the inner wall surface of the branched air pipe, ensuring smooth gas flow, with good effects and high efficiency.

[0007] The above patent applications and the prior art also have the following defects:

[0008] The existing fixed dust detectors have limited detection ranges and are mostly installed on buildings, such as ceilings, walls, and columns, and cannot be close to the activity range, resulting in poor dust detection accuracy. Some portable detectors need to be carried by personnel, and the personnel are exposed to high-concentration dust environments, which endangers the health of the detection personnel. Moreover, for the high-precision gravimetric dust detection, after collecting dust once, it is necessary to weigh and clean the dust before the next detection can be carried out, and continuous multi-period detection cannot be performed.

Detailed implementation manners

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] The detection unit 41 further includes two closing doors 411 and a pushing block 412. The detection component 4 further includes a pushing plate 42. One end of the detection box 1 is open. The two closing doors 411 are slidably engaged with the open end of the detection box 1. When the detection box 1 moves to the position of the separator 31, the pushing block 412 drives the two closing doors 411 to move under the push of the pushing plate 42, opening the open end of the detection box 1.

[0049] Carry the detection component 4 and the collection component 3, place the protective cover 2 at the facial mouth and nose. The collection component 3 passes the external dust and air into the separator 31. The separator 31 separates the air and dust, passes the air into the protective cover 2, and passes the dust into the detection box 1 below the separator 31. After a specified time, the detection box 1 moves, the closing door 411 closes, the detection box 1 weighs the internal dust. The next detection box 1 moves to the position below the separator 31. During the movement to the position below the separator 31, the pushing plate 42 squeezes the pushing block 412 to move, and the pushing block 412 drives the two closing doors 411 to move, causing the closing doors 411 to move away from the detection box 1.

[0050] With the portable detection component 4 and the collection component 3, it is possible to collect and detect the dust concentration during the movement of personnel, without location limitation for dust detection, and closer to the personnel's activity range, making the dust detection more accurate. The separator 31 separates air and dust, passes the air into the protective cover 2 for personnel to breathe, and passes the dust into the detection box 1 for detection, which can provide dust-free air for the detection personnel to breathe, prevent the detection personnel from staying in a dust environment for a long time, and protect the safety of personnel. The detection box 1 detects the dust concentration by weighing, with higher detection accuracy. Through the movement of multiple detection boxes 1, they move to the bottom of the separator 31 in sequence for dust detection, which can detect the dust concentration in multiple time periods.
