Abstract

The new dust removal device for crushed stone sand making discharging comprises a sand outlet, a sand collecting hopper, a telescopic sand conveying pipe, an elastic rope and a dust cover; the sand gathering hopper is fixed below the sand outlet, the dust shielding cover is arranged on the sand pile, and the sand gathering hopper, the telescopic sand conveying pipe, the elastic rope and the dust shielding cover are connected into a whole, can be integrally telescopic and are fixed and erected between the sand outlet and the sand pile; when the sand outlet discharges materials, the sand materials enter from the sand collecting hopper, fall to a sand pile or the ground from the top through the telescopic sand conveying pipe and the dust shielding cover, and are gradually and correspondingly contracted and shortened under the self contraction force and the support of the sand pile along with the upward stacking of the sand materials, so that the dust shielding cover is always attached to the sand pile; the dust removal device for the gravel-making sand discharging can be widely applied to the fields of mines and the like, and particularly relates to the aspect of dust removal of the gravel-making sand discharging.

Description

Dust collector of rubble system sand ejection of compact

Technical Field

The utility model relates to a dust removal field especially relates to a dust collector of rubble system sand ejection of compact.

Background

In the process of crushing stone into sand, the stone materials are subjected to links such as primary coarse crushing, secondary fine crushing, sand making, screening, belt conveying and the like to convey sand materials with various particle sizes to a sand material discharge port. The discharge port is generally 5 to 10 meters away from the ground, so that the sand material discharged from the discharge port is usually required to fall to a ground sand pile from a height of 5 to 10 meters. During the falling of the sand, a large amount of dust flies into the air due to the disturbance of the air and the interference between the sand and the sand pile. In the past, most of dust removal modes in the link adopt that sand materials are humidified and then fall to a sand pile from a discharge hole, or a fence is arranged around the falling sand materials, or generated raised dust is directly sprayed; the dust removal modes are difficult to achieve the dust removal effect, and the difficulty of sand making and dust removal by using broken stones is just the link.

The utility model has the following contents:

the utility model discloses to the above-mentioned not enough of prior art and product, make following design: a dust collector of rubble system sand ejection of compact, install a flexible falling passageway of sand material between rubble system sand discharge gate and ground sand heap, it can thoroughly solve the raise dust pollution problem that the sand material ejection of compact falls the in-process and produces.

The dust removal device for crushed stone sand making discharging comprises a sand outlet, a sand collecting hopper, a telescopic sand conveying pipe, an elastic rope and a dust cover; the sand gathering hopper is fixed below the sand outlet, the dust shield is tightly attached to the sand pile, and the whole telescopic falling channel is erected between the sand outlet and the sand pile; the sand gathering hopper, the telescopic sand conveying pipe, the elastic rope and the dust shielding cover are connected into a whole and can be integrally telescopic to form a sand material telescopic falling channel.

According to the dust removal device for discharging crushed stone-made sand, when the sand outlet discharges, sand enters from the sand gathering hopper and falls to a sand pile through the telescopic sand conveying pipe and the dust shielding cover, and because the whole process is carried out in the telescopic channel, dust is rarely raised; along with the continuous discharging, the sand pile is gradually piled up high, and at the moment, the telescopic sand conveying pipe is gradually and correspondingly contracted and shortened under the self contraction force and the support of the sand pile, so that the dust shielding cover is always attached to the sand pile.

The dust removal device for the gravel-making sand discharging can be widely applied to the fields of mines and the like, and particularly in the aspect of gravel-making sand discharging and dust removal, the telescopic channel is simple to manufacture, the problem of dust pollution caused by gravel discharging can be thoroughly solved, and remarkable ecological and social benefits are achieved.

Fig. 1 is a schematic view of the present invention.

Reference numerals: 1-sand outlet, 2-sand gathering hopper, 3-telescopic sand conveying pipe, 4-elastic rope, 5-dust shield, 6-winch, 7-fixed rod and 8-sand pile.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

as shown in the attached drawing, the dust removal device for the sand making and discharging of the crushed stones comprises a sand outlet (1), a sand gathering hopper (2), a telescopic sand conveying pipe (3), an elastic rope (4), a dust cover (5), a winch (6), a fixing rod (7) and a sand pile (8).

The dust removal device for crushed stone sand making discharging is characterized in that a sand gathering hopper (2), a telescopic sand conveying pipe (3), an elastic rope (4) and a dust shielding cover (5) are connected into a whole and can be integrally telescopic to form a sand telescopic falling channel; the sand gathering hopper (2) is fixed below the sand outlet (1), the dust cover (5) is tightly attached to the sand pile (8), and the whole telescopic falling channel is erected between the sand outlet (1) and the sand pile (8);

when sand materials are discharged from the sand outlet (1), the sand materials enter from the sand gathering hopper (2) and fall to a sand pile or the ground through the telescopic sand conveying pipe (3) and the dust cover (5); because the whole sand material falling process is carried out in the telescopic channel, dust is rarely raised; in the process of falling of the sand, the sand pile is gradually piled up along with the accumulation of the sand, and at the moment, the telescopic sand conveying pipe (3) is gradually and correspondingly contracted and shortened under the action of contraction force and the support of the sand pile, so that the dust shielding cover is always attached to the sand pile.

The above is only the preferred embodiment of the present invention, so the range of the implementation of the present invention can not be determined according to the above, and the equivalent changes and decorations made according to the content of the present invention should all belong to the scope covered by the present invention.

Claims

1. A dust removal device for crushed stone sand making and discharging comprises a sand outlet, a sand gathering hopper, a telescopic sand conveying pipe, an elastic rope and a dust cover; the method is characterized in that: the sand gathering hopper is fixed below the sand outlet, and the dust shielding cover is arranged on the sand pile; the sand gathering hopper, the telescopic sand conveying pipe, the elastic rope and the dust cover are connected into a whole and can be integrally telescopic to form a sand material telescopic falling channel; when the sand outlet discharges materials, the device gradually contracts correspondingly along with the stacking height of the sand materials to shorten, so that the dust shielding cover is always attached to the sand pile.
