Description
Technical Field
The invention relates to the technical field of ventilation equipment, in particular to a ventilation nozzle structure.
Background
The cleaning operation of the ship boiler belongs to the first-level limited space operation, but the ventilation problem always troubles constructors. Because there is a large amount of ashes in the boiler, when carrying out the ventilation with mechanical draft's plastics tuber pipe, a large amount of dusts just can be raised in the stove, is unfavorable for the construction operation, more brings occupational health harm for inside constructor. One-level limited space operation ventilation is a necessary prerequisite, for this reason, the production department is also trying to use cold wind leather hose (the compressed air pipe that the air mill used) to ventilate, but discovery in the in-service use, because cold wind leather hose pressure is big, often can "get rid of the pipe" when fixed not good, easily cause the object to the personnel and strike the injury, the ventilation effect is not very good moreover to can produce the condition that personnel came in and go out the difficulty after original plastics tuber pipe used.
Therefore, a ventilation device which is small in size, convenient to carry, convenient to install and does not occupy the space of the road door needs to be prepared according to the field construction environment and the construction requirement.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a ventilation nozzle structure which is uniform in airflow dispersion, safe to use, convenient to install and small in size.
In order to achieve the purpose, the technical scheme of the invention is to design a ventilation nozzle structure, which comprises a cover plate, a dust screen, a ventilation part, an adjusting part and an air pipe which are arranged in sequence; the edge of the cover plate is provided with an ear hole, the edge of the ventilation part is provided with a connecting hole, the dustproof net is positioned between the cover plate and the ventilation part, and the ear hole is connected with the connecting hole through a connecting piece; the surface of the cover plate is provided with an air outlet, and the surface of the ventilation part is provided with a ventilation hole; a ventilation air channel is arranged in the ventilation part, and the diameter of the ventilation air channel is the same as that of the ventilation hole; the ventilation part and the adjusting part are integrally formed, an air quantity adjusting knob is arranged outside the adjusting part, and the air quantity adjusting knob is connected with an adjusting sealing plate positioned on the inner side of the adjusting part through a connecting rod; the adjusting portion is provided with a connecting portion connected with the air pipe, threads are arranged on the outer side of the connecting portion, and threads are correspondingly arranged on the air pipe.
Compared with a cold air leather hose, the ventilation nozzle provided by the invention is provided with the plurality of air outlets, the air outlet is uniformly dispersed, the raised dust is reduced, the support of the ventilation nozzle is placed on the ground when the ventilation nozzle is used, the weight of the support is increased due to the steel balls arranged inside the support, the potential safety hazard caused by the 'throwing' of the ventilation nozzle is avoided, and the movable support is arranged on the air pipe due to the longer length of the air pipe, so that the stability of the air pipe is improved.
According to the preferable technical scheme, an interlayer is arranged on the outer side of the ventilating part, a fixed support is fixedly arranged on the interlayer on the outer side in the radial direction of the ventilating part through the center of the ventilating part, the fixed support is of a hollow structure, the interlayer on the outer side of the ventilating part is communicated with the fixed support, and steel balls are arranged in the interlayer.
Set up fixing support and intermediate layer mainly used in the portion of ventilating outside the portion of ventilating and improve the stability of the portion of ventilating, avoid the portion of ventilating to take place the phenomenon of "getting rid of the pipe" in the use, fixing support's bottom and lateral part are equipped with the entry of placing the steel ball, can increase or reduce the steel ball as required, make things convenient for the installation and the use of ventilation nozzle.
Preferably, the width of the fixed support is 1/3-1/2 of the width of the ventilation part. The fixed support is used for stably placing the ventilation nozzle on the ground or a plane or connecting the ventilation nozzle with a fixed position through the fixed support, and the stability of the ventilation nozzle is influenced if the width of the fixed support is too narrow.
As an optimal technical scheme, the dust screen is a curved surface, a sealing strip is arranged at the joint of the dust screen and the cover plate, and the edge of the sealing strip is matched with the edge of the outmost air outlet of the cover plate. Because the dust content of operating space is high, for avoiding taking place to block up through the nozzle, consequently be equipped with the dust screen in air outlet department, the dust screen is stainless steel or plastics, and the dirt is held in the gap of dust screen and apron connection easily to difficult clearance is consequently done on the coplanar with the edge of sealing strip and the edge of the outermost air outlet of apron, avoids owing to have the recess, causes the deposition phenomenon
Preferably, the cross-sectional view of the ventilation air duct inside the ventilation part is a multi-fillet bent air duct or a multi-tip-angle bent air duct. The bent air duct is helpful to increase wind resistance, so that the air outlet of the ventilation nozzle is softer, the air flow distribution is more uniform, and the raised dust is reduced,
Preferably, the ventilation part and the adjustment part are made of rubber. The rubber material has light weight and is convenient to carry and install.
Preferably, the air volume adjusting button is electrically connected with a controller, the controller is electrically connected with the air compressor, and the controller is fixedly arranged on the fixed support or the outer layer of the adjusting part. The air volume adjusting button is mainly used for adjusting air volume, the adjustment of the air volume depends on the compressor on one hand and the adjusting sealing plates on the other hand, the adjusting sealing plates are semicircular, the two adjusting sealing plates are away from each other by a certain distance, and the rotating angle of the adjusting sealing plates is changed through the adjusting button to adjust the air volume.
As a preferable technical scheme, the air outlet is in a drop shape and is rotationally symmetrical along the center of the cover plate. Because the ventilation air duct is a bent air duct, the air flow is blown out spirally and is more uniform when being blown out from the ventilation nozzle through the water drop-shaped air outlet.
As the preferred technical scheme, be equipped with the removal support on the tuber pipe, the removal support is equipped with annular opening clamping part and supports the base, clamping part and support base integrated into one piece and be hollow structure, the inside steel ball that is equipped with of hollow structure, support base below or side are equipped with the steel ball and put into the mouth. The mobile support can be removed or added according to the needs.
As the preferred technical scheme, a silica gel sealing gasket is arranged at the joint of the adjusting part and the connecting part. The sealed pad of silica gel plays sealed effect on the one hand, and on the other hand prevents that connecting portion and tuber pipe from receiving too closely, causes deformation, influences the life of ventilation nozzle.
The invention has the advantages and beneficial effects that: the air outlet of the ventilation nozzle is more uniform and dispersed through the design of the air outlet holes of the cover plate; through the shape design of the ventilation air duct, the wind speed of wind resistance reduction is increased, and the raised dust caused by the ventilation nozzle is reduced; the air inlet amount can be changed by adjusting the closing plate and controlling the common adjustment of the air inlet amount of the compressor, the air volume can be adjusted according to the use condition, and the cost is saved; through the design of fixing support and movable support, the effectual phenomenon of getting rid of the pipe of avoiding has improved the security of using.
