Abstract

The utility model discloses a negative pressure dust hood and a conveyor belt using the same, wherein the negative pressure dust hood comprises a hood body and a negative pressure pipeline connected with the hood body, a dust isolation curtain is arranged on the periphery of the hood body, the dust isolation curtain is hung below the periphery of the hood body, and the isolation curtain is made of flexible transparent material; compared with the prior art, the utility model has the following advantages: the dust generating source is wrapped and isolated as much as possible by designing the isolating curtain, so that the dust raising range is effectively controlled, and meanwhile, the dust leakage is effectively prevented by combining a negative pressure environment; the flexible isolation curtain can adapt to any installation environment, and the transparent material is convenient to observe.

Description

Negative pressure dust collection cover and conveyer belt using same

Technical Field

The utility model relates to a dust removal environmental protection technical field especially relates to a negative pressure dust cage and conveyer belt of using thereof.

Background

Dust hoods are common devices for isolating dust generating sources, and the dust hoods are optimally used for completely enclosing and isolating the dust generating sources, but the dust hoods can interfere with the operation, maintenance and observation and monitoring of the process flow. However, the common dust collecting hood with a conical structure has limited package isolation on a dust generating source, and has the defects of large required air volume, low light energy consumption and poor isolation effect.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a negative pressure dust hood.

The utility model discloses a realize through following technical scheme: the conveying belt comprises a conveying belt body, wherein at least one end of the conveying belt body is provided with a negative pressure dust collection cover, and the negative pressure dust collection cover comprises a cover body and a negative pressure pipeline connected with the cover body; the cover body is conical, the top of the cover body is connected with the negative pressure pipeline, and the periphery of the bottom of the cover body is hung with a dust isolating curtain; the dust isolation curtain is made of a flexible material, the flexible material is made of a PEVA material, and the whole dust isolation curtain is covered on the end part of the conveying belt.

Compared with the prior art, the utility model has the following advantages: the dust generating source is wrapped and isolated as much as possible by designing the isolating curtain, so that the dust raising range is effectively controlled, and meanwhile, the dust leakage is effectively prevented by combining a negative pressure environment; the flexible isolation curtain can adapt to any installation environment, and the transparent material is convenient to observe.

Detailed Description

The embodiments of the present invention will be described in detail below, and the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Example 1

A conveyor belt with a negative pressure dust hood comprises a conveyor belt body 4, wherein the negative pressure dust hood is arranged at each of two ends of the conveyor belt body 4 and comprises a hood body 1 and a negative pressure pipeline 2 connected with the hood body 1, a dust isolating curtain 3 is arranged on the periphery of the hood body 1, and the dust isolating curtain 3 is hung below the periphery of the hood body 1; the isolation curtain 3 hung on the periphery of the cover body 1 is designed, the dust generating source is wrapped and isolated as much as possible through the isolation curtain 3, the dust raising range is effectively controlled, meanwhile, the negative pressure environment is combined, on one hand, the isolation dust generating source can be effectively covered, meanwhile, the hanging type is convenient to mount and dismount, the position between the isolation curtain 3 and the cover body 1 can be flexibly adjusted, and the isolation curtain is convenient to adapt to various mounting environments; when the dust-proof mask works, the mask body 1 is in negative pressure, and the gaps between the isolation curtains 3 cannot leak dust;

in order to wrap and isolate the dust generating source as much as possible and effectively control the dust raising range, the dust isolating curtain is integrally covered on the end part of the conveyor belt, or the end part of the conveyor belt is inserted into the dust isolating curtain; the structure has better protection effect;

in order to be conveniently used in various environments, the isolation curtain 3 is made of flexible materials, can be well attached to equipment of instruments, and reduces gaps; the flexible material can be a high polymer material, such as PVC, PE, PEVA and other materials which are commonly used;

furthermore, for the convenience of observation, the isolation curtain 3 may be made of a transparent material, or a port may be separately formed in the opaque isolation curtain, and a transparent material, glass or a transparent polymer material may be used, preferably a transparent polymer material, such as PVC.

The cover body 1 can be designed to be conical, the hanging curtain is arranged at the bottom of a cone, and the negative pressure pipeline 2 is arranged at the top of the cone; the arrangement is more favorable for airflow and dust to enter the negative pressure pipeline, avoids the cover body with a folded angle at the top from generating dead angles at the top, and reduces the negative pressure dust collection effect.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.

Claims

1.
