Embodiment 1

[0014] Example 1: Refer to the attached figure 1 . A special dust removal device for dry sand grinding and dust removal complete equipment, which includes a dust collector 4 and a vibrating screen 5, and the dust collector 4 is an existing technology. The vibrating screen 5 can either adopt the existing technology or the vibrating screen designed by the applicant. No matter which kind it is, it is only used as a supporting assembly of the dust removal device of this application. Above the vibrating screen is arranged a water mist pressure dust suction hood 5-2. The water mist pressure dust suction hood 5-2 is provided with a discharge port and a dust suction port. The dust suction port is connected to the suction pipe 4-4 The dust collector 4 is connected, and the water mist pressure dust suction hood 5-2 is built with one or more water mist nozzles 5-3. When there are two water mist nozzles 5-3, two water mist nozzles 5 3 are arranged at intervals and the water mist hoods sp...

Embodiment 2

[0015] Example 2: On the basis of Example 1, a dust removal method of a special dust removal device for dry sand grinding and dust removal equipment, a water mist pressure dust suction hood 5-2 located on the vibration screening mechanism, the crushing process The dust is first covered by the water mist cover 5-4 produced by the water mist nozzle 5-3, and when it falls to the vibrating screen 5-1, the trace dust not covered by the water mist cover 5-4 is covered by the water mist The dust-pressure suction hood 5-2 sucks the suction pipe 4-4 into the dust collector 4 to remove dust. At this time, the suction in the inverted cone suction hood 5-5 located under the vibrating screening mechanism (vibrating screen discharge port) The tube blows up the dust in the vibrating falling sand of the vibrating screen 5-1 and sucks it into the dust collector through the suction pipe 4-1 to remove dust, and the clean and water-free (less moisture) sand passes through the discharge suction hood...

Abstract

The invention relates to a dedicated dust removal device for dry sand-grinding dust removal complete equipment and a dust removal method. The dedicated dust removal device can effectively remove dust generated by sand grinding, and can substantially reduce energy consumption and noise, and comprises a dust remover and a vibrating screen, wherein a water mist dust pressing suction hood is arrangedabove the vibrating screen, and the dust suction mouth of the water mist dust pressing suction hood is communicated with the dust remover through a wind suction pipe; and the discharge port of the vibrating screen is provided with an inverted cone-shaped dust suction hood, and a dust suction pipe is arranged in the inverted cone-shaped hood and is communicated with the dust remover. The inventionhas the advantages that: firstly, the water mist dust pressing, the primary dust removal and the secondary dust removal in the process of sand making can be realized, and the energy consumption and the noise are greatly reduced; secondly, the clean and pure sand is obtained, and the purpose of all-weather operation is realized; and finally, in the application, the water generated when the water mist dust pressing is adopted to suck water dust can be sucked by heat energy generated by the mutual collision between sands in the process of vibrating sand screening, and can be blown by the wind, thereby obtaining dry sand with less water.

Description
