Description

Technical Field

[0001] This utility model belongs to the field of dust control technology in iron ore mining, and in particular relates to a dust control device used in the iron ore mining process. Background Technology

[0002] During iron ore mining, dust (rock dust, mine dust) is one of the main sources of pollution. Workers need to wear masks to isolate themselves from the dust and prevent it from entering their respiratory tract.

[0003] Because conventional high-breathability non-woven fabric is relatively soft and cannot maintain outward expansion, when breathing against the face, only the space near the breathing area expands, and the air pressure mainly acts on this area. Therefore, only a local area bears the filtering work. Since the actual filtering range is relatively small, the breathing resistance is relatively large, and the mask fabric itself is also very uncomfortable when it is pressed against the mouth and nose, resulting in the relatively low practicality of conventional masks.

[0004] Therefore, we propose a dust control device for iron ore mining to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problem of the low practicality of conventional masks by proposing a dustproof device for use in iron ore mining.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A dustproof device for iron ore mining includes a support frame with elastic bands connected to it. The elastic bands are a pair. The front of the support frame is wrapped with non-woven fabric, and an elastic band is clamped around the non-woven fabric. The rear of the non-woven fabric is sandwiched between the support frame and the elastic band, and a sealing ring is fixedly installed at the rear of the elastic band. The elastic bands are worn over the ears, covering the mouth and nose. The sealing ring seals the gap between the support frame and the face. The support frame expands the non-woven fabric outwards, keeping it inflated to increase the filtration range and reduce breathing resistance. The elastic band is removed, and the non-woven fabric is then removed. New non-woven fabric is sandwiched between the support frame and the elastic band, and the elastic band clamps and secures the rear of the non-woven fabric to the support frame. This method of replacing only the non-woven fabric reduces material waste.

[0007] Preferably, the support includes a main frame, with an arc-shaped frame fixedly connected to the front of the main frame. The front end of the elastic band is fixedly connected to the rear end of the main frame. The rear part of the non-woven fabric is fitted over the main frame, and the arc-shaped frame supports the inside of the non-woven fabric. The sealing ring is fixedly installed on the main frame. The arc-shaped frame expands the non-woven fabric outward, keeping it in a bulging state to prevent contact between the non-woven fabric and the mouth, while ensuring smooth internal airflow and uniform internal air pressure for easy and smooth breathing.

[0008] Preferably, a fixing groove is provided at the rear of the main frame, and the front part of the sealing ring is fixedly engaged inside the fixing groove. The fixing groove increases the fixing connection range between the bracket and the sealing ring, and improves the firmness between the bracket and the elastic hoop.

[0009] Preferably, the outer periphery of the main frame is provided with a fastening groove, which is matched with an elastic hoop, and the rear part of the non-woven fabric is embedded in the fastening groove. The elastic hoop compresses the non-woven fabric into the fastening groove, increasing the clamping friction between the rear part of the non-woven fabric and the support and the elastic hoop, thereby improving the stability of the non-woven fabric and the support installation.

[0010] Preferably, the elastic hoop includes an elastic hoop body, with a buckle fixedly connected inside the elastic hoop body. The elastic hoop body and the buckle are an integral structure, and the buckle is matched with a buckle groove. The elastic hoop body and the buckle press against the outside of the non-woven fabric. The elasticity of the elastic hoop body acts on the buckle, pressing the non-woven fabric tightly against the main frame and the buckle groove. By prying the elastic hoop body outwards, the buckle disengages from the buckle groove, allowing the non-woven fabric to be removed. New non-woven fabric is then installed between the support and the elastic hoop, facilitating the replacement of the non-woven fabric.

[0011] Preferably, the sealing ring includes a rubber band, the upper end of which is fixedly connected to a U-shaped rubber piece. The U-shaped rubber piece is fixedly connected to the upper part of the main frame, and the rubber band is fixedly connected to a fixing groove. The U-shaped rubber piece 42 is used to seal the gap between the bridge of the nose and the support, and the rubber band is used to seal the gap between the cheeks, thereby improving the seal between the support and the face.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. Wear the elastic band over your ears so that the support covers your mouth and nose. Seal the gap between the support and your face using the sealing ring. Use the support to push the non-woven fabric outwards to keep it bulging, increasing the breathing filtration range and reducing breathing resistance. Remove the elastic band and then remove the non-woven fabric. Place a new non-woven fabric between the support and the elastic band, and use the elastic band to clamp and fix the back of the non-woven fabric, keeping it on the support. By replacing only the non-woven fabric, you can reduce material waste.

[0013] 2. Use the arc-shaped frame to expand the non-woven fabric outwards, keeping it in a bulging state to prevent it from contacting the mouth, while ensuring smooth internal airflow and uniform internal air pressure for easy and smooth breathing.

[0014] 3. Use elastic clamps to squeeze the non-woven fabric into the buckle groove, increasing the clamping friction between the back of the non-woven fabric and the bracket and elastic clamps, thereby improving the stability of the non-woven fabric and bracket installation.

[0015] 4. Utilize the elastic force of the elastic hoop body to press the non-woven fabric onto the main frame and the buckle through the elastic hoop body and the buckle; pry the elastic hoop body outward to disengage the buckle from the buckle, remove the non-woven fabric, and install a new non-woven fabric between the bracket and the elastic hoop for easy replacement of the non-woven fabric.

[0016] 5. Use U-shaped leather pieces 42 to seal the gap between the bridge of the nose and the support, and use leather bands to seal the gap between the cheeks, thereby improving the seal between the support and the face. Attached Figure Description
