Problems solved by technology

Although water mist pressure dust, primary dust removal, and secondary dust removal have been realized, energy consumption and noise have been reduced, but the disadvantage is that the dust collector still has power consumption and noise

Embodiment Construction

[0022] This embodiment mainly improves the dedusting device and dedusting method of the patent CN102000625A (dedusting device and dedusting method for complete equipment for dry sand grinding and dedusting). In this embodiment, the water mist cover produced by the water mist nozzle of the prior art can be retained, and dust removal can be carried out under the condition of removing the rest of the dust removal settings in the prior art solution; it can also be completely removed from the prior art solution Dust removal with all dust removal settings.

[0023] The dust removal device of this embodiment includes a dust suction system 2 , an exhaust pipe 3 and a curved water tank 27 . The dust collection system 2 is composed of a sand grinding workshop 21, a dust leakage floor 22, an underground air duct 24, an underground water mist nozzle 25, a dust collection plate 26 and a water storage tank 28; wherein, the upper part of the sand grinding workshop 21 is provided with a cavit...

Abstract

The present invention relates to a device for eliminating dust by using strong ascending airflow. The device is characterized in that the device includes a dust collecting system, an exhaust pipe andan arc-shaped water tank; the dust collecting system is composed of a sand grinding workshop, a dust leakage floor, an underground air passage, an underground water mist nozzle, a dust suction board and a water storage tank; and in an operation process, when airflow flows through the arc-shaped water tank, the flow rate is increased, the pressure is lowered, and the high-pressure airflow in the lower part of the exhaust pipe flows upward and flows to the outside from an exhaust port; external airflow forces the dust in the sand grinding workshop to pass through the dust leakage floor into theunderground air passage and then pass through water mist along with the airflow; a part of the dust is covered with the water mist and falls down; trace dust not covered with the water mist collides the dust suction board along with mixed airflow and is stuck by first dust suction wet cloth on the dust suction board; and then clean air after dust collection enters the exhaust pipe and flows out from the exhaust port. The device does not consume electric power and is free from noise.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a dust removal device in dry sand grinding production. Background technique [0002] Patent CN102000625A (special dedusting device and dedusting method for complete set of equipment for dry sand grinding and dedusting) provides a technical solution of water mist pressure dedusting dedusting hood and vibrating screen discharge port equipped with an inverted cone dust hood. The generated water mist cover covers most of the dust generated by the cone sand making machine and the vibrating mechanism, and the leaked dust is sucked into the dust collector through the dust suction cover and negative pressure suction pipe for dust removal. Although water mist pressure dust, primary dust removal, and secondary dust removal have been realized, energy consumption and noise have been reduced, but the disadvantage is that the dust collector still has power consumption and noise.
