[0001] The utility model relates to the technical field of dust detection, especially to a dust early warning device for industrial safety detection. BACKGROUND

[0002] The detection of dust concentration in the environment during engineering construction is an important detection parameter. Dust concentration detection is a technique for monitoring suspended particulate matter in the air, including dust, smoke, industrial dust, etc. By measuring the concentration of these particulate matters, we can assess air quality, which is crucial for environmental protection, industrial safety, and public health. In mining, metallurgy, cement manufacturing, and other industrial environments, it is necessary to set up dust detectors at the construction site to prevent explosions caused by high dust concentration. Currently, the dust concentration detection equipment used in these industries mostly adopts a fixed integrated design, which ensures the integrity, stability, and sealing of the equipment.

[0003] Because the humidity in the air can cause a large deviation in the measurement, especially when the relative humidity is high, the average particle size increases due to the growth of hygroscopic components in the dust, causing the measured value to be larger, which in turn affects the detection results.

[0004] In the Chinese utility model patent with publication number (CN222719381 U), a dust concentration detection and warning device is disclosed, which includes a laser dust instrument. A sound-light alarm is provided on the laser dust instrument. An air inlet of the laser dust instrument is connected to an air inlet pipe. A plurality of through holes are formed in the outer wall of the air inlet pipe in the circumferential and length directions. A mesh basket is provided at each through hole. A drying bag is provided inside each mesh basket. A cover plate is provided at each through hole of the air inlet pipe. The utility model can make the laser dust instrument more convenient for detecting dust content in high-humidity air.

[0005] However, this design still has some defects. Although the drying bag absorbs moisture in high-humidity air, it may also absorb some dust in the air while absorbing moisture, which will adversely affect the accuracy of dust detection. SUMMARY

DETAILED DESCRIPTION

[0024] The embodiments of the present utility model will be described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and cannot be understood as a limitation of the present utility model.

[0025] The dust early warning device for industrial safety detection of the embodiments of the present utility model will be described below in conjunction with the drawings.

[0026] As Figures 1-2 shown, the dust early warning device for industrial safety detection of the embodiments of the present utility model can include laser dust instrument 20, dry air tank 30.

[0027] Among them, the laser dust instrument 20 is provided with audible and light alarm 40, air extraction part 50 and detection element 60.

[0028] It should be noted that the air extraction part 50 described in this embodiment can be selected as a fan, and its function is to suck the external high-humidity air into the detection channel 203. In this process, the high-humidity air is first mixed with dry air according to a predetermined ratio, and then the mixed air enters the detection area 2032 for dust detection by the detection element 60. This method not only can effectively reduce the humidity of the mixed air, but also will not produce adsorption effect on the dust particles, so as to realize the dehumidification operation of the high-humidity air without affecting the accuracy of the dust detection, and the operation is simple and the cost is low.

[0029] It should be noted that when the detection element 60 described in this embodiment detects the dust in the mixed air in the detection channel 203, the audible and visual alarm 40 will be started immediately to alarm if the detection result exceeds the standard. In addition, the dust concentration detection standard set by the detection element 60 matches the process step of mixing the high-humidity air and the dry air in a specific ratio.

[0030] The laser dust instrument 20 is respectively provided with an air inlet 201 and an air outlet 202, and a detection channel 203 is formed between the air inlet 201 and the air outlet 202, wherein the air suction member 50 and the detection element 60 are both arranged in the detection channel 203. The detection channel 203 is sequentially provided with an air inlet area 2031, a detection area 2032 and an air outlet area 2033, wherein the air inlet area 2031 is arranged adjacent to the air inlet 201, the detection area 2032 is arranged adjacent to the detection element 60, and the air outlet area 2033 is arranged adjacent to the air outlet 202.

[0031] The dry air tank 30 is connected to the detection channel 203. The dry air tank 30 is provided with a conveying pipe 301, wherein the conveying pipe 301 is connected to the air inlet 201, and the conveying pipe 301 is provided with a control member 3011. The input end of the air inlet area 2031 is provided with a three-way pipe 70, and the air inlet 201 and the conveying pipe 301 are both connected to the three-way pipe 70.

[0032] It should be noted that the air inlet 201 and the three-way pipe 70, and the conveying pipe 301 and the three-way pipe 70 described in this embodiment are both designed as a one-way conveying structure. Specifically, the external high-humidity air flows into the three-way pipe 70 in a one-way manner from the air inlet 201, and the dry air in the dry air tank 30 is conveyed into the three-way pipe 70 in a one-way manner from the conveying pipe 301.

[0033] It should be noted that the control member 3011 (such as a valve) described in this embodiment can flexibly control the opening and closing and the air conveying speed of the dry air tank 30.

[0034] Specifically, when the dust detection and early warning operation is performed in a high-humidity air environment, the operator first starts the air suction member and the control member 3011. After the air suction member is started, the external high-humidity air is sucked into the three-way pipe 70 in a one-way manner through the air suction port, and the dry air in the dry air tank 30 is conveyed into the three-way pipe 70 in a one-way manner from the conveying pipe 301. In this process, the high-humidity air and the dry air are mixed in a specific ratio, and the mixed air then enters the detection area 2032 for dust detection by the detection element 60. The detected mixed air enters the air outlet area 2033 and is finally discharged from the air outlet 202.

[0035] Further, as Figure 1As shown, the dust early warning device for industrial safety detection can further include a frame 10, and the laser dust instrument 20 and the dry air tank 30 are arranged on the frame 10 respectively. In actual installation, the laser dust instrument 20 and the dry air tank 30 can be installed on the frame 10 respectively, and then the whole frame 10 can be installed.

[0036] In conclusion, the dust early warning device for industrial safety detection can effectively reduce the humidity of the mixed air by mixing the high-humidity air and the dry air in a specific ratio, and the process will not have adsorption effect on the dust particles. In this way, the dehumidification operation of the high-humidity air can be completed without affecting the accuracy of the dust detection, and the operation is simple and the cost is low.
