Description
Technical Field
The utility model relates to a mining equipment technical field, concretely relates to dust keeper of ore chute.
Background
Chutes, generally referred to as troughs on the ground that carry material from a high point to a low point, are a common type of apparatus used in mining and metallurgy operations to effect the transfer of mineral material. In mining or ore dressing, ores need to be crushed or ground, so that the ores contain a large amount of dust, and when the ores slide from a high place to a bottom conveying belt, the dust is rapidly diffused to the periphery due to huge impact force. Dust diffusion refers to the process of dust generation from a dust source, suspension in the surrounding air and diffusion and spread. The dust dispersion can be considered as a result of the continuous action of two air streams: one is a gas stream such as an induced gas stream, a shear gas stream, a hot gas stream, etc. that is generated along with the production process, and is called a primary dusty gas stream. The primary dusty airflow lifts the powder material to dusty the material to form local dusty air. The other is indoor airflow formed by ventilation or convection of cold and hot airflow, called secondary airflow. The secondary air flow can take away the dust-containing air from local places, so that the dust-containing air can be diffused and spread in a workshop.
The existing dust suppression device cannot rapidly collect dust generated on an ore chute, so that a large amount of floating dust is still diffused in the air, and the problem is difficult to fundamentally solve. A large amount of dust firstly influences the working environment, secondly causes damage to equipment, and in addition, a large amount of minerals contained in the dust cannot be recovered to cause waste.
SUMMERY OF THE UTILITY MODEL
To the problem that exists in the background art, the utility model provides a novel dustproof of ore chute device can collect fast and retrieve the dust, reduces the dust effectively and overflows.
In order to achieve the above purpose, the solution of the present invention is: a novel dust prevention device for an ore chute comprises a conveying belt, wherein dust prevention plates are arranged on two sides of the conveying belt, a cover plate is arranged at the top of each dust prevention plate, and a relatively closed space is formed between each cover plate and each dust prevention plate; the chute is respectively provided with a dust cover at the upstream and the downstream of the relative conveyer belt; the dust cover comprises a cover body, and the bottom of the cover body is provided with an opening which is fixedly connected with the cover plate; the dustproof device is provided with a dust suppression curtain, and the dust suppression curtain is fixed on the support through a clamping plate.
Preferably, the cover body is narrow at the top and wide at the bottom.
Preferably, the horizontal distance between the center of the dust cover and the discharge hole of the chute is 1.5-3 m.
Furthermore, at least one dust suppression curtain is arranged between the dust cover and the chute. Preferably, the dust suppression curtain is arranged at a position 0.3-0.5 meter away from the discharge port of the chute.
Furthermore, the width of the dust suppression curtain is matched with the width of the inner side of the dustproof plate, and the bottom of the dust suppression curtain extends to the conveying belt. Dust suppression curtains are arranged at intervals of 0.3-0.5 m.
Further, the top of the cover body is provided with an opening, a spray header is installed at the opening, and one end of the spray header in the cover body is connected with the spray header.
The utility model has the advantages that: the dust suppression curtain is adopted to weaken the diffusion speed of a large amount of raised dust generated when the ore falls; the dust cover generates vortex to cut off air flow, so that dust can be quickly and effectively collected and prevented from diffusing; settling the collected dust and dropping the dust onto the conveyor belt in a spraying manner; on the other hand, the dust suppression curtain partitions the conveying belt into multiple sections, controls air flow, effectively reduces dust overflow, guarantees the environmental quality of a factory area, reduces equipment loss, and meanwhile recovers minerals contained in dust.

Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
As shown in fig. 1-4, the novel dust-proof device of the ore chute comprises a conveyor belt 2, dust-proof plates 3 are arranged on two sides of the conveyor belt 2, a cover plate 4 is arranged on the top of each dust-proof plate 3, and the cover plate 4 and the dust-proof plates 3 form a relatively closed space; the chute 1 is provided with a dust cover 5 at the downstream relative to the conveyer belt 2, the dust cover comprises a cover body 51 which is fixedly connected with the cover plate 4, and the bottom of the cover body 51 is provided with an opening; the dustproof device is provided with a dust suppression curtain 6, and the dust suppression curtain 6 is fixed on a support 7 through a clamping plate.
The cover 51 has a shape with a narrow top and a wide bottom, such as a trapezoid or a cone. When ore or ore fines fall from the chute 1 to the conveyor belt 2, the large impact forces cause the dust to become suspended in the surrounding air and spread rapidly around. The effect of dust cover 5 lies in, when the dust stretches along with the air current, when through dust cover 5, because the space volume is by little sudden grow, form local vortex in the cover body 51 naturally, the dust gets into dust cover 5 under this effect fast for the dust is in dust cover 5 department gathering and not excessive, thereby reaches the technological effect of collecting the dust fast. Through a large number of attempts and optimization, the distance between the central position of the discharge port of the chute 1 and the central position of the dust cover 5 is 1.5-3 m, which is the optimal horizontal distance, when the distance is too small, dust does not reach the dust cover 5, and when the distance is too large, the belt on the conveying belt 2 is inconvenient to replace.
Preferably, at least one dust suppression curtain 6 is arranged between the dust cover 5 and the chute 1, so that the dust diffusion speed of a discharge port of the chute 1 can be reduced. Preferably, a dust suppression curtain 6 is arranged at the discharge port of the chute 1 within 0.3-0.5 m.
Preferably, the conveyor belt 2 can be provided with a plurality of dust suppression curtains 6, and the preferable interval of each dust suppression curtain is 0.3-0.5 m. Preferably, the feeding end and the discharging end of the conveying belt 2 are respectively provided with a dust suppression curtain 6. The dust suppression curtain 6 partitions the conveyor belt into multiple sections, so that dust is suppressed by settling step by step. The width of the dust suppression curtain 6 is matched with the width of the inner side of the dust guard, and the bottom of the dust suppression curtain 6 extends onto the conveying belt 2 without interfering the normal discharge of ores. The dust suppression curtain 6 is fixed on the bracket 7 through a splint.
Further, the top of the cover body 51 is provided with an opening, a spray pipe 53 is installed at the opening, and one end of the spray pipe 53 is connected with the spray head 52. The amount of water in the showerhead 52 can be adjusted as desired. The spraying function is to capture the dust collected in the dust cover 5 by the sprayed water mist, and the dust sinks into the ore heap under the action of gravity, thereby achieving the effect of sedimentation. The spraying mode can be manual operation or automatic spraying.
To further control dust overflow, dust covers 5 may be provided both upstream and downstream of the chute 1 relative to the conveyor belt 2, as shown in figure 1. It is also possible to provide a dust cover 5 (not shown) only downstream of the chute 1 relative to the conveyor belt 2. The number of dust covers 5 or dust suppression curtains 6 may be adjusted according to specific needs and is not limited to the number shown in fig. 1-4.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should be considered as not departing from the scope of the present invention.
