Abstract
The utility model discloses an air lock funnel which comprises a funnel shell, wherein one side of the funnel shell is provided with an inlet orifice; the upper end of the funnel shell is provided with a dustproof cover; the inlet orifice is provided with a curtain damper; and the dustproof cover and the curtain damper on the funnel shell have an effect of locking air after coal is discharged in a bin. The air lock funnel has a simple structure for preventing coal dust from overflowing, is environmental-friendly, energy-saving, durable and wear-resistant and has long service life.
Description
Technical field
The utility model belongs to the material transfer equipment technical field, particularly a kind of lock gas funnel.
Background technology
At present, band conveyor is widely used in the mass transport in the industrial and agricultural production.With the coal conveying is example, band conveyor of the prior art is delivered to feed bin top with coal, the coal plough that is arranged on the load-transfer device unloads the coal on the load-transfer device to the feed bin of below, contain a large amount of coal dusts in the coal, in the time of in falling to feed bin, a large amount of dust smog that can rise, dust smog outwards fills the air, and makes the working environment severe exacerbation; Simultaneously also, dust smog causes Coal Loss because of escaping.
The utility model content
The purpose of this utility model provides and a kind ofly prevents that dust from escaping, the lock gas funnel of environmental protection and energy saving.
For achieving the above object, the technical solution of the utility model is: a kind of lock gas funnel, comprise that a side offers the funnel housing of inlet point, and described funnel housing upper end is provided with dust boot, and the inlet point place is provided with check apron.
Be provided with rotating shaft in the described funnel lower housing portion, be connected with baffle plate in the rotating shaft, funnel housing madial wall is provided with and the corresponding closing plate of baffle plate.
Be connected with the axis that stretches to the funnel outside in the described rotating shaft.
The swash plate inclination alpha that described inlet point place links to each other with funnel housing side is 45 °-60 °.
Described swash plate inclination alpha is 55 °.
Described funnel housing side is provided with access opening.
Compared with prior art, the utility model has the advantages that:
1, be provided with dust boot in funnel housing upper end, the inlet point place is provided with the soft check apron that vertically blocks inlet point, act as feed bin and is subjected to lock gas behind the coal, and is simple in structure, escapes environmental protection and energy saving, durable wear, long service life to prevent coal dust.
2, be connected with baffle plate in rotating shaft, funnel housing madial wall is provided with and the corresponding closing plate of baffle plate, escapes to prevent coal dust; In rotating shaft, be connected with the axis that stretches to the funnel outside, control rotating shaft to realize the upset of baffle plate by axis, easy and simple to handle; On baffle plate, be provided with reinforced rib, improved equipment intensity greatly, prolong the service life of baffle plate.
3, funnel housing side is provided with access opening, easy access equipment and observation funnel enclosure interior situation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right elevation of Fig. 1.
The specific embodiment
Lock gas funnel as depicted in figs. 1 and 2, it comprises that a side offers the funnel housing 1 of inlet point 8, is provided with dust boot 2 in funnel housing 1 upper end, and inlet point 8 places are provided with the soft check apron 3 that vertically blocks inlet point 8, act as feed bin 6 and be subjected to lock gas behind the coal, escape to prevent coal dust.In funnel housing 1 bottom, be provided with rotating shaft 9, rotating shaft 9 two ends are fixedly mounted on the funnel housing 1 by the bearing 10 in the bearing seat 11, be connected with baffle plate 7 in rotating shaft 9, funnel housing 1 madial wall is provided with and baffle plate 7 corresponding closing plates 15, escapes to prevent coal dust.In rotating shaft 9, be connected with and stretch to funnel housing 1 exterior axis 12, control rotating shaft 9 to realize the upset of baffle plate 7 by axis 12.Funnel housing 1 side is provided with access opening 13, easy access equipment and observation funnel housing 1 inner case.For improving equipment intensity, on baffle plate 7, be provided with reinforced rib 5.
Swash plate 81 inclination alpha that inlet point 8 places link to each other with funnel housing 1 side are 45 °-60 °, and preferred swash plate inclination alpha is 55 ° in the present embodiment.
The material of dust boot 2 adopts the Q235B steel plate, and the material of check apron 3 adopts the thick antifriction rubber band of 4mm, durable wear, long service life.Be processed with seal groove in the bearing seat 11, place the felt sealing in the groove, prevent that coal dust from entering bearing 10.
In the use, damper shaft 9 and bearing 10 and bearing seat 11 will guarantee right alignment 0.15mm, and baffle plate 7 is rotated flexibly, and the jam phenomenon can not be arranged.
When the utility model uses, be connected by the waterproof edge of angle steel flange 14 with feed bin 6, fixed, and can prevent that the coal dusts in the feed bin 6 from escaping.
