Fig. 2 is a structural schematic diagram of the dust suction air duct of the present invention;

Fig. 3 is a structural schematic diagram of a fireproof separating part.

Detailed ways

With reference to Fig. 1, Fig. 2, Fig. 3, a kind of fire-proof type dust-absorbing grinding machine comprises casing 1, dust-absorbing bellows 5 and fire-proof separator 6, and casing 1 is provided with control panel 14, and described casing 1 The front side is provided with a suction port communicating with the dust suction bellows 5. The suction port is composed of a main suction port 2 and an auxiliary suction port 3 arranged below the main suction port 2. A grinding wheel is arranged in front of the main suction port 2. 4. The grinding wheel 4 is connected with a motor 13 to drive it to rotate. During the grinding process, a large amount of dust is sucked away through the main suction port 2, and the dust falling below is sucked away through the auxiliary suction port 3.

The fireproof separator 6 is composed of an outer air duct wall 7 with openings at both ends and an inner air duct wall 8 with openings at both ends. The outer air duct wall 7 is cylindrical, and the inner air duct wall 8 is large at the top and small at the bottom. Trumpet-shaped, the upper end of the inner air duct wall 8 is combined with the upper end of the outer air duct wall 7, a rotating air duct 9 is formed between the inner air duct wall 8 and the outer air duct wall 7, and the air outlet 15 is arranged outside On the air duct wall 7 and communicated with the rotating air duct 9, the lower end of the outer air duct wall 7 is connected with a dust bag 10, which is a plastic bag, and the upper end of the outer air duct wall 7 is connected with a Filter bag 11, the filter bag is a cloth bag. In addition, the fireproof separator 6 can also be only a cylindrical structure with openings at both ends, and the air outlet direction of the air outlet 15 is set to be blown to the dust bag after mixing with water mist toward one side, or the wind direction of the air outlet 15 is along the fireproof separator. The inner wall of 6 makes the swirling wind containing dust blow to the dust bag and also can obtain similar fire prevention and dust removal effect.

The inner air duct wall 8 is provided with a water spray port 12, and the water spray port 12 is suitably arranged in the middle of the inner air duct wall 8. In order to enhance the degree of dispersion of the water mist, a spray nozzle is provided at the water outlet end of the water spray port. Structure, the spray structure can be set to intermittent spray mode.

When working, the dust inhaled from the main suction port and the auxiliary suction port first enters the rotating air channel to form a rotating wind, and then enters down to the bottom of the inner air channel wall, and mixes with the water mist sprayed from the water spray port. On the one hand, it can reduce the temperature of the dust and prevent fires. On the other hand, it can also increase the weight of the dust after it is wet. Most of the dust will naturally fall into the dust bag, and a small part of the dust will enter with the airflow. The filter bag, the wind is discharged through the filter bag, and the dust adheres to the inner wall of the filter bag to achieve the purpose of dust suction and filtration. It has strong absorption, good dust removal effect, and easy to remove dust.
