Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figures 1 and 2, a kind of ventilation unit provided by the utility model, is made up of blast cap 1, outer air funnel 2, interior air funnel 3, screen pack 4, mounting panel 5 and dust board 6.Wherein, blast cap 1 is made up of roof 9 and the sidewall around roof 9 to downward-extension 10, and roof 9 is one-body molded with sidewall 10, and roof 9 and sidewall 10 surround the structure under shed.Outer air funnel 2 and interior air funnel 3 is disposed with from outside to inside in blast cap 1, outer air funnel 2 is enclosed within the outside of interior air funnel 3, the roof 9 of the top of outer air funnel 2, interior air funnel 3 and blast cap 1, by weld or other modes are fixed together, forms double-layer labyrinth type air intake passage structure between the sidewall 10 of blast cap 1 and outer air funnel 2 and between outer air funnel 2 and interior air funnel 3.
The cylindrical shell of air funnel 2 is outside provided with multiple first ventilating opening 7, formation ground floor ventilates, in the present embodiment, first ventilating opening 7 is arranged on the top of outer air funnel 2 and the junction of blast cap 1 roof 9, and circumferentially interval is arranged, the setting height(from bottom) of the first ventilating opening 7 can be improved so as far as possible, the whole height of ventilation unit is reduced.The cylindrical shell of interior air funnel 3 is offered multiple second ventilating opening 8, forms the second layer and ventilate, the installation site of the second ventilating opening 8 is lower than the position of the first ventilating opening 7, and the second ventilating opening 8 equally circumferentially interval is arranged.Such air enters backward upper flowing from the air intake passage between the sidewall 10 and outer air funnel 2 of blast cap 1, the passage between outer air funnel 2 and interior air funnel 3 is entered by first ventilating opening 7 at top, flow downward again, middle air communication channel is entered from the second ventilating opening 8 of lower position, and then form double-layer labyrinth type air intake passage, realize the ventilation demand of accumulator box.What flow through due to air is double-layer labyrinth type air intake passage, while guaranteeing air quantity, wind speed can be made to reduce, be beneficial to the sedimentation of the particles such as dust in air.
In practical application, can according to the volume of ventilation unit, determine the quantity of the first ventilating opening 7 and the quantity of the second ventilating opening 8 and arrangement mode, but will ensure that the extreme higher position of the second ventilating opening 8 is in the below of the first ventilating opening 7.In the utility model, the first ventilating opening 7 has 3, is uniformly distributed circumferentially the top of air funnel 2 outside, and shape is strip circumferentially; Second ventilating opening 8 circumferentially goes to upper and lower two row's distributions on interior air funnel 3, and often arranged 3, two ranked second ventilating opening 8 can be crisscross arranged, and also can symmetrical parallelly arrange, and the shape of the second ventilating opening 8 is similarly strip circumferentially.
As depicted in figs. 1 and 2, be provided with screen pack 4 between blast cap 1 and outer air funnel 2, screen pack 4 is positioned at the porch of air intake passage, and position is lower than the position of the first ventilating opening 7, in order to first to filter out the sand and dust in air in ventilation process.Outer air funnel 2 is tightly connected by dust board 6 with the bottom of interior air funnel 3, dust board 6 by screw fixedly mount outside air funnel 2 with on interior air funnel 3, also sealing gasket etc. can be set up between dust board 6 and the cylindrical shell of outer air funnel 2 and interior air funnel 3, dust board 6 is positioned at the below of the second ventilating opening 8, in order to collect the dust of sedimentation after double-layer labyrinth air intake passage.
In the below of air intake passage, mounting panel 5 is fixedly connected with lower end outside the barrel of outer air funnel 2, and mounting panel 5 is provided with screw hole, in order to ventilation unit is fixed on equipment corresponding position.The bottom surface of mounting panel 5 is a little more than the bottom margin of outer air funnel 2 and interior air funnel 3, ventilation unit is when installing with accumulator box, mounting panel 5 is butted on the outer surface of accumulator box, be connected on the ventilating opening on default accumulator box body bottom outer air funnel 2, play guiding and fixing effect, make the installation of ventilation unit simpler and easy, more firmly.
This ventilation unit is fixedly mounted on accumulator box top, and during ventilation, due to the stop of blast cap 1, air-flow can not direct access arrangement, but air intake passage from below flows into.Air is first through the screen pack 4 of air intake passage porch, filter out the sand and dust of larger volume in air and a part of impurity, air-flow upwards flows, enter between outer air funnel 2 and interior air funnel 3 via the first ventilating opening 7, air-flow changes flow direction and flows downward, air-flow is at screen pack 4, under the acting in conjunction of the first ventilating opening 7, while guaranteeing air quantity, wind speed is reduced, dust contained in air-flow settles down further, drop on dust board 6, by dust board 6 centralized collection, now through filtering further, substantially the impurity such as the sandstone dust that can affect batteries work are not contained in air-flow after sedimentation, finally enter batteries by the second ventilating opening 8, realize the object of batteries ventilation, meet the security protection demand of batteries simultaneously.
In the present embodiment, dust board 6, screen pack 4 can periodic cleanings, improve ventilation unit to the security protection demand of batteries.
Ventilation unit provided by the utility model, the equipment that not only can be used in special protection requirements, as on accumulator box, also can be applicable to any need in the equipment of ventilation.The double-layer labyrinth type safeguard structure that ventilation unit is formed after installing, both normally can work by the components and parts in guarantee equipment, can improve the reliability that equipment works under severe operating environment simultaneously.
As mentioned above, plan content given by reference to the accompanying drawings, can derive similar technical scheme.In every case be the content not departing from technical solutions of the utility model, any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
