Coarse sand dust-removal and recovery device

Abstract

The invention discloses a coarse sand dust-removal and recovery device. The device comprises a dust remover and further comprises a sand discharging machine connected with the dust remover, wherein the sand discharging machine comprises a charging shell, a discharging hopper and a controller, the controller is installed on the charging shell, and the charging shell is installed on the discharging hopper; external air is blown into the charging shell from an air inlet, passes through gravels on a first discharging plate and is blown to the dust remover from an air outlet, so that dust removal of the gravels is realized through the dust remover; and after dust removal of the gravels on the first discharging plate is completed, the controller controls a first transmission assembly to rotate, the first transmission assembly drives the first discharging plate to turn over, the gravels on the first discharging plate fall onto a second discharging plate, when a gravity sensor detects that the weight of the gravels on the second discharging plate reaches a preset threshold value, the controller controls the first transmission assembly to reset the first discharging plate and controls a second transmission assembly to rotate so that the gravels on the second discharging plate can fall into the discharging hopper and then fall into a charging basket, and control over the gravel discharging speed is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the field of dust collectors, in particular to a coarse sand dust removal and recovery device. Background technique [0002] In the process of sand and gravel regeneration, it is necessary to remove dust from the sand and gravel to obtain sand grains that meet the specifications. Because the amount of dust in the sand and gravel is large and pollutes the environment too much, the cost of manual removal is too high. In order to protect the environment and obtain no impurities The sand and gravel need to use professional equipment to dedust the sand and gravel. At present, the sand and gravel dust removal equipment is relatively complete, generally using bag filter and cyclone dust collector, etc., but after sand and gravel dust removal, the problem of sand and gravel recovery also needs to be solved. Since the sand and gravel dust removal is generally in a confined space, the sand and gravel can be rec...

Problems solved by technology

At present, the sand and gravel dust removal equipment is relatively complete, generally using bag filter and cyclone dust collector, etc., but after sand and gravel dust removal, the problem of sand and gravel recovery also needs to be solved

Since the sand and gravel dust removal is generally in a confined space, the sand and gravel can be recycled directly through the lower hopper after dust removal, but the small outlet of the lower hopper will block the sand and gravel, which will affect the discharge efficiency
