Description

Waterproof ventilator

Technical Field

The invention belongs to the field of environmental protection, and particularly relates to a waterproof ventilator which is mainly used in places such as coal bunkers, plants and the like which need ventilation, need prevention of indoor dust overflow and can be waterproof.

Background

The sustainable development strategy of China is continuously pushed and the environmental protection laws and regulations are increasingly strict, the storage mode of coal in a coal storage yard is gradually changed from the open air to a closed storage mode, and the construction of a fully-closed coal bunker is vigorously developed in China in recent years. However, the existing totally-enclosed coal bunker has the problems of insufficient air circulation, high dust concentration and the like, so that the operating environment of workers is deteriorated, and the possibility of explosion caused by high dust concentration exists. The coal dust explosion releases a large amount of heat energy, the instantaneous temperature can reach 2300-2500 ℃, the great destruction effect is achieved, and the lives of operators are threatened.

The indoor dust can be mainly divided into settleable dust and non-settleable dust, the dust which is easy to cause dust explosion is mainly settleable dust or the settleable dust and the non-settleable dust are in a crossed dense area, and the dust is mainly concentrated in the middle upper area of a coal yard, such as the height of the coal yard is 50 meters, and the dust is mainly concentrated at the height of 20-40 meters. Meanwhile, the coal yard is sealed by the color steel plate, the specific heat capacity of air is 3.14 times of that of iron, and when the ambient air temperature under sunlight is 40 ℃, the surface temperature of the color steel plate reaches 94.2 ℃, so that a baking effect is formed in the coal yard, the indoor temperature is greatly increased, and the risks of dust explosion and spontaneous combustion of coal are increased.

In addition, many peripheral environmental sensitive points such as the neighborhood residential area of totally closed coal yard have the demand of noise protection in certain height, and lower part shutter can have certain blocking effect to the noise, but because it belongs to the sound leakage structure, not only must ventilate, but also must prevent the noise, hardly satisfies the requirement of environmental protection to noise control simultaneously. At present, many manufacturers and research units in the market adopt some dust settling methods, but all the methods are not ideal. The ventilation problem becomes the biggest constraint factor for building the closed coal bunker.

Disclosure of Invention

Based on the problems, the invention provides the waterproof ventilator which realizes the functions of water prevention, ventilation, dust suppression and the like. The invention is installed on the middle upper part of the coal bunker on the basis of the existing ventilation system, thereby greatly improving the ventilation condition of air in the bunker, preventing the formation of coal dust cloud, preventing the risk of dust explosion, realizing totally-closed storage operation and zero emission of dust pollution.

A waterproof ventilator is characterized by comprising a base plate and a ventilation cup; a plurality of ventilation cups are arranged on the substrate; one end edge of the substrate is provided with a connecting tongue-and-groove; the ventilating cup consists of a bedplate and a cup cylinder; the bedplate is arranged in the middle of the cup cylinder, one side of the bedplate is provided with a horn cylinder, and the other side of the bedplate is provided with a wake flow hip; the cup barrel is formed into a whole by the horn barrel and the wake flow hip, an included angle between the horn barrel and the wake flow hip is 130 degrees, and a plurality of vent holes are formed in the barrel wall of the horn barrel and the barrel wall positioned at the lower edge of the horn barrel; the cross section of the opening of the horn cylinder is oval; the wake flow hip is in a horn-shaped oblate structure, a large ellipse is in contact with the table board surface, and a small ellipse is arranged on the other side of the wake flow hip.

The base plate is a metal contour plate made of steel or aluminum, and is provided with a tongue-and-groove profiling in the long-edge direction, and the base plate are matched through the tongue-and-groove in use and are combined for use. Circular holes are arranged on the surface of the substrate in a plum blossom shape and used for mounting parts such as a ventilation cup and the like;

the cardboard uses with the ventilation cup is supporting, and the material is the ring shape sheet metal of metal product also can be nylon products, and has the breach on the circle of inboard, and the buckle cooperation on breach and the platen.

The material of the ventilation cup can be metal products or nylon products. The structure can be integrally cast, or be separately manufactured and then welded or riveted.

The bedplate is a circular ring-shaped thin plate, and the diameter and the thickness of the excircle of the thin plate are the same as those of the clamping plate; the inner circle is elliptical and is matched with the end part of the oblique section of the cylindrical opening. L-shaped buckles are evenly arranged on the periphery of the bedplate and are matched with the clamping plates to fasten the ventilation cup.

The wake flow hip is in a horn-shaped oblate structure, and the large opening end of the horn cylinder is in contact with the platform surface.

The leather pad is a circular ring type sheet rubber product, has buffering and waterproof functions, and is arranged on the ventilating cup and between the clamping plate and the outer side of the substrate.

The working principle of the invention is as follows:

when the base plate is installed on the middle upper part of the coal bunker, the long edge and the ground form a certain angle according to the slope of the roof of the coal bunker, so that the horn cylinder opening on the outer side of the base plate is inclined towards the underground, and the wake flow hip on the inner side of the base plate is upward.

When the outside wind comes without rain, the horizontal wind and the wind coming from the oblique lower part enter the coal bunker through the horn cylinder opening and the lower small hole of the ventilation cup to perform ventilation and heat exchange, and the horn cylinder opening is large, the wake flow hip opening is small, so that the wind can be accelerated properly to increase the ventilation and heat exchange efficiency in the coal bunker; the dust in the bin reaches the wake flow cylinder when overflowing from the inside to the outside, and can not overflow when encountering obstacles because the dust is not a straight opening.

When no wind rains, rainwater falling from the top of the coal bunker and the sky flows through the ventilation cup, the ventilation cup is of a circular tube structure, the rainwater can smoothly flow down, and the imperforate long surface of the cylindrical opening shields the perforated short surface below the perforated long surface to prevent water;

when strong wind and heavy rain exist, rainwater entering from the front face of the horn tube is formed, because the horn tube and the wake flow hips form an angle, a small amount of rainwater entering is blocked by the wake flow hips and cannot enter a coal yard, and the rainwater gathered at the horn tube flows down through the small hole in the lower side face.

The invention greatly improves the ventilation condition of air in the bin, prevents the formation of dust cloud, prevents dust explosion risk, realizes totally-enclosed storage operation and has zero emission of dust emission.
