Description

Technical Field

[0001] This utility model relates to the field of processing technology for dust detection equipment, and in particular to an atmospheric dust content detection device. Background Technology

[0002] The purposes of atmospheric dust concentration detection are multifaceted, primarily revolving around environmental protection, public health, scientific research, and policy formulation. This involves detecting PM2.5 levels. 10 The detection of atmospheric dust content, including PM2.5, is used to determine the degree of particulate matter pollution in the air, assess whether air quality meets standards, promptly detect extreme pollution weather such as sandstorms and smog, and provide data support for emergency response. Dust can penetrate deep into the respiratory tract, triggering asthma, cardiovascular diseases, etc. Detection helps remind the public to take protective measures (such as wearing masks and reducing outdoor activities), analyze the correlation between dust concentration and respiratory and cardiovascular diseases, monitor dust emissions from sources such as factories, mines, and construction sites, and promote the upgrading of pollution control technologies. The core objectives of atmospheric dust content detection are to protect public health, improve environmental quality, support scientific decision-making, and provide key data support for climate change research, ecological protection, and sustainable development.

[0003] Currently, before testing floating dust, testing equipment is needed to collect the dust. A fan periodically draws dusty air from outside into the collection box, and then the dust is collected manually at regular intervals. The dust and impurities are collected into a container and sent for testing to complete the collection and testing purpose. However, since most of the dust is blocked at the filter screen, the collection box needs to be opened manually and the filter screen needs to be scraped off before the dust can be collected. This method is inconvenient for manual operation, increases the complexity of the operation, and easily poses a safety hazard to the operator from inhaling floating dust.

[0004] Therefore, it is necessary to provide an atmospheric dust content detection device to solve the above-mentioned technical problems. Utility Model Content

[0005] In response to the above situation and to overcome the defects of the existing technology, this utility model provides an atmospheric dust content detection device. In the existing dust and impurity collection operation, since most of the dust is blocked at the filter screen, it is necessary to manually open the collection box and scrape off the filter screen before the dust can be collected. This method is inconvenient for manual operation, increases the complexity of operation, and easily poses a safety hazard of inhaling dust.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An atmospheric dust content detection device includes: a base plate, a housing, a fan, an exhaust pipe, and a collection box;

[0008] A box is mounted on the top surface of the base plate. The box is a hollow cylindrical structure. A fan is installed on the top surface of the box. An exhaust pipe is installed at the bottom of the box and is connected to the interior of the box. A complete airflow path is formed between the exhaust pipe, the box, and the fan. A collection box is installed at the bottom of the box. The collection box is a frustum-shaped structure and is connected to the box. A threaded groove is opened on the inner circumference of the bottom opening of the collection box. A placement box is installed inside the bottom opening and is threadedly engaged with the bottom opening of the collection box. A processing mechanism is installed in the upper inner part of the box.

[0009] In one embodiment, the processing mechanism comprises a dust filter, a mounting platform, a vibration motor, mounting rods, and connecting rods. The dust filter is located between the exhaust duct and the fan. A mounting platform is installed in the middle of the dust filter. Connecting rods are installed in a circular array on the outer side of the top surface of the mounting platform. The top of the connecting rods is connected to the middle of the mounting rods. The mounting rods are generally cross-shaped, and their extended ends are bolted to the inner wall of the housing. A vibration motor is installed on the top surface of the mounting platform, and the vibration motor is electrically connected to an external power supply.

[0010] In one embodiment, the dust removal filter is preferably an electrostatic dust removal filter structure.

[0011] In one embodiment, a support rod is installed at the bottom of each exhaust pipe, and the bottom of the support rod is connected to the base plate.

[0012] In one embodiment, a one-way valve is installed inside the exhaust pipe.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model allows outside air to enter the housing through the exhaust pipe by starting the fan. After the processing mechanism adsorbs the floating dust, the air is discharged through the top of the fan. After the exhaust is completed, the fan is turned off, and the processing mechanism causes the dust to fall into the placement box below. After the timed collection, the person only needs to screw the placement box in to take it out and install a new placement box.

[0015] This utility model uses a dust filter to adsorb dust onto the surface facing the bottom of the box. After collection, a vibration motor is started to make the dust blocked by the dust filter fall down. The box and other operating parts are supported by a support rod. The outward-expanding support method helps to increase the space for taking out the box and makes manual operation more convenient. Attached Figure Description

[0028] Working principle of this utility model:

[0029] During operation, by starting the fan 3, outside air enters the chamber 2 through the exhaust pipe 4. Dust is drawn into the chamber 2 by the dust filter 61 and is collected on the surface facing the bottom of the chamber 2. After collection, the vibration motor 63 is started, causing the dust blocked by the dust filter 61 to fall. The air is discharged through the top of the fan 3.
