Abstract
The utility model relates to a mineral powder ventilation device, in particular to a mineral powder ventilation device used for ventilation of powder in a mineral powder container. The mineral powder ventilation device comprises a cloth bag, frameworks and a hoop. The cloth bag is sleeved outside the frameworks, and the cloth bag is fixed on an opening portion of the frameworks through the hoop. A plurality of framework reinforcing ribs are welded on the frameworks. A connecting flange is welded on the opening portion of the frameworks. The mineral powder ventilation device has the advantages of being simple, compact and reasonable in structure, capable of improving circumstances of poor circulation and blocking of mineral powder in the mineral powder container and preventing the mineral powder from floating in the air and polluting the air, convenient to manufacture, install and dismantle, and long in service life.
Description
Technical field
The utility model relates to a kind of breeze gas permeable devices, specifically is used for the ventilative of breeze container breeze.
Background technology
Relate to the occasion of using breeze, because the character of breeze is similar to water, having flowing power, and equally with water having an air impermeability.So when breeze flows out from the container that only has an outlet, will certainly make to produce negative pressure in the container, cause breeze to flow out and have some setbacks.Simultaneously because mineral powder granular is little, when flowing out, swims in easily in the air and do not precipitate, to environment.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of breeze gas permeable devices is provided, and can improve the situation that breeze circulates freely, stops up in the breeze container, stops simultaneously breeze to float in the air and pollutes.
According to the technical scheme that the utility model provides, the breeze gas permeable devices comprises cloth bag, skeleton and anchor ear, it is characterized in that: skeleton is set with cloth bag outward, and cloth bag is fixed on the skeleton opening part by anchor ear.
The a plurality of skeleton reinforced ribs of welding on the described skeleton.
Described skeleton opening part is welded to connect flange.
Described skeleton is welded into cylindrical shape by a plurality of round steel.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Can improve the situation that breeze circulates freely, stops up in the breeze container; Stoping breeze to float in the air pollutes; Easy to make, install and convenient disassembly; Long service life.
Description of drawings
Fig. 1 is the utility model front view.
Fig. 2 is the utility model birds-eye view.
Description of reference numerals: 1-cloth bag, 2-skeleton, 3-anchor ear, 4-butt flange, 5-skeleton reinforced rib.
The specific embodiment
Following the utility model is further described in connection with the embodiment in the accompanying drawing:
Shown in Fig. 1 ~ 2, the utility model mainly comprises cloth bag 1, skeleton 2 and anchor ear 3.
Described skeleton 2 opening parts are welded to connect flange 4, and butt flange 4 is used for connecting other container joint.
The utility model is installed in the breeze container when using, and breeze is installed in the cloth bag 1.Cloth bag can prevent that dust from overflowing when making air keep circulation, the dust that will overflow is gathered in cloth bag, and is free from environmental pollution; The unimpeded generation of avoiding negative pressure of air can smooth and easyly be flowed out breeze.Skeleton 2 so that cloth bag 1 after filling breeze, can not cave in.
Claims (4)
1. a breeze gas permeable devices comprises cloth bag (1), skeleton (2) and anchor ear (3), it is characterized in that: the outer suit of skeleton (2) cloth bag (1), cloth bag (1) is fixed on skeleton (2) opening part by anchor ear (3).
