Abstract

The present invention is a kind of dedusting technology and device for gravel sand making and discharging, comprising a sand outlet, a sand gathering bucket, a telescopic sand delivery pipe, an elastic rope, and a dust cover; the sand gathering bucket is fixed under the sand outlet, The dust cover is placed on the sand pile, and the sand gathering bucket, the telescopic sand delivery pipe, the elastic rope, and the dust cover are integrated into one, which can be stretched as a whole, fixed and upright between the sand outlet and the sand pile; When discharging from the sand port, the sand material enters from the sand accumulating hopper, falls from above to the sand pile or the ground through the telescopic sand conveying pipe and the dust cover, and as the sand material is piled up, the telescopic sand conveying pipe Under the support of its own contraction force and the sand pile, the stretching and falling channel of the sand material shrinks and shortens accordingly, so that the dust cover is always close to the sand pile; the dust removal technology and The device can be widely used in mines and other fields, especially in the field of dust removal for crushed stone sand making.

Description

A dust removal technology and device for crushed stone sand making and discharging

technical field

The invention relates to the field of dedusting, in particular to a dedusting technology and device for making sand out of crushed stones.

Background technique

In the process of gravel sand making, the stone materials go through primary coarse crushing, secondary fine crushing, sand making, sieving, belt conveying and other links, and the sand materials of various particle sizes are transported to the sand material outlet. The discharge port is generally 5 to 10 meters above the ground, so the sand material often needs to be dropped from a height of 5 to 10 meters to the ground sand pile when it is discharged from the discharge port. During the landing process of the sand material, due to the turbulence of the air and the impact of the sand material and the sand pile, a large amount of dust floats into the air. In the past, most of the dust removal methods in this link used the sand material to be humidified and then dropped from the discharge port to the sand pile, or to install fences around the sand material drop, or to directly spray the generated dust; the above dust removal methods It is difficult to achieve the dust removal effect by all methods, and the difficulty of dust removal in gravel sand making is precisely this link.

Invention content:

The present invention aims at the above-mentioned deficiencies of the prior art and products, and makes the following design scheme: the dedusting technology and device for the discharge of crushed stone sand are installed between the crushed sand discharge port and the ground sand pile. A stretching and falling channel for sand material can completely solve the problem of dust pollution generated during the process of sand material discharging and falling.

The dedusting technology and device for the discharge of crushed stone sand making include a sand outlet, a sand gathering bucket, a telescopic sand delivery pipe, an elastic rope, and a dust cover; the sand gathering bucket is fixed under the sand outlet to cover The dust cover is closely attached to the sand pile, and the entire telescopic drop channel stands upright between the sand outlet and the sand pile; the sand gathering bucket, telescopic sand delivery pipe, elastic rope, and dust cover are integrated into one, which can be stretched as a whole. Constitute the stretching and falling channel of sand material.

The dust removal technology and device for sand making and discharging of crushed stones, when discharging from the sand outlet, the sand enters from the sand gathering bucket and falls to the sand pile through the telescopic sand conveying pipe and the dust cover. The process takes place in the telescopic channel, so dust is rarely generated; as the discharge continues, the sand pile is gradually piled up. At this time, the telescopic sand delivery pipe is gradually shrunk and shortened under its own contraction force and the support of the sand pile. , so that the dust cover is always close to the sand pile.

The dedusting technology and device for sand making and discharging of crushed stones can be widely used in fields such as mines, especially in the aspect of dust removal for sand making and discharging of crushed stones. Since the telescopic channel is simple to manufacture, it can completely solve the problem of crushed stones being discharged. The problem of dust pollution caused by raw materials has significant ecological and social benefits.

Detailed ways

Below in conjunction with accompanying drawing, the present invention is described in detail:

As shown in the accompanying drawings, the dedusting technology and device for the discharge of crushed stones include a sand outlet (1), a sand gathering bucket (2), a telescopic sand delivery pipe (3), and an elastic rope (4) , dust cover (5), winch (6), fixed rod (7), sand pile (8).

The dedusting technology and device for the discharge of crushed stone sand making, its sand gathering bucket (2), telescopic sand conveying pipe (3), elastic rope (4), and dust cover (5) are connected into one, which can be integrated telescopic to form a telescopic falling channel for sand; the sand gathering bucket (2) is fixed under the sand outlet (1), the dust cover (5) is close to the sand pile (8), and the entire telescopic falling channel Stand upright between the sand outlet (1) and the sand pile (8);

The dedusting technology and device for the discharge of crushed stone sand making, when the sand material is discharged from the sand outlet (1), the sand material enters from the sand gathering bucket (2), passes through the telescopic sand delivery pipe (3) and the dust shield The cover (5) falls to the sand pile or the ground; since the entire sand material falling process occurs in the telescopic channel, dust is rarely generated; during the sand material falling process, the sand pile gradually Heap height, at this moment telescopic sand conveying pipe (3) under the effect of shrinkage force and sand heap support gradually correspondingly shrinks and shortens, makes its dust cover to be close to on the sand heap all the time.

The dedusting technology and device for sand making and discharging of crushed stones can be widely used in fields such as mines, especially in the aspect of dust removal for sand making and discharging of crushed stones. Since the telescopic channel is simple to manufacture, it can completely solve the problem of crushed stones being discharged. The problem of dust pollution caused by raw materials has significant ecological and social benefits.

The above are only preferred embodiments of the present invention, so the scope of implementation of the present invention cannot be determined accordingly, that is, equivalent changes and decorations made according to the content of the description of the present invention should all fall within the scope of the present invention.
