Description
Technical field
The utility model relates to dry powder extinguisher Canning Technique fields, filling for dry powder extinguisher more particularly, to one kind
The filling head of air charging system.
Background technique
It is filling that fire extinguisher carries out dry powder usually under negative pressure vacuumized conditions.As shown in Figure 1, existing vacuum filling head includes
1 ' of vacuum suction chamber that lid is closed around fire extinguisher bottleneck and connect with sealing bottle, is arranged in the filling at the top of 1 ' of vacuum suction chamber
Powder channel includes 3 ' of 2 ' of external shell and inner hose, and 3 both ends ' of hose are connected with 2 ' of shell sealing, 3 ' outer wall of hose and shell
2 ' inner walls form 4 ' of inflating cells.It is true to carrying out taking out in bottle body by the negative pressure device being connected with 1 ' of vacuum suction chamber when powder filling
Do-nothing operation, then dry powder is perfused by 3 ' of hose into bottle body, after a period of time, to 4 ' pressurising of inflating cells, 3 ' of hose closure
(as shown in Figure 2) terminates powder filling.Frequently due to 3 ' of hose deformation, it is very easy to damage, maintenance and replacement cost are higher；Secondly,
Powder filling operation cannot stop immediately, and filling accuracy is not high, need to do over again after exceeded, larger workload；Again, bottleneck edge holds
Easily there is accumulated powder, not only waste, but also influence subsequent operation, when powder is trickled down at the scene, is also easy to cause environmental pollution；Most
Afterwards, since filling rear negative pressure is unable to Rapid reversal, filling head is not easy to be detached from bottle body, extends the operating time.
Summary of the invention
The utility model provides a kind of filling head for the filling air charging system of dry powder extinguisher, it is therefore intended that solves to use
Existing filling head is time-consuming and laborious when filling, precision is not high, low efficiency, problem at high cost.
To achieve the above object, the utility model can take following technical proposals:
Filling head described in the utility model for the filling air charging system of dry powder extinguisher, including cooperate with sealing bottle
The vacuum suction chamber with pumping pipe fitting, it is characterised in that: be provided with dry powder punishment in advance chamber, institute above the vacuum suction chamber
It states dry powder punishment in advance top of chamber and offers concora crush through-hole, the concora crush through-hole is matched with the seal plug that lifting cylinder drives, and is done
It is communicated on powder punishment in advance chamber side wall and tilts upward and extend to the intracorporal feed pipe of chamber, the charging tube end is provided with hinge point
Swing closure plate at the top of tube wall, dry powder punishment in advance bottom of chamber portion are provided through vacuum suction chamber and extend to the intracorporal material feeding of bottle
Pipe.
The pumping pipe fitting is two, and is uniformly and symmetrically distributed on the side wall of the vacuum suction chamber.
Dry powder punishment in advance bottom of chamber portion is throat structure.
The vacuum suction chamber and dry powder punishment in advance chamber bolt are connected, and the filling tube includes being located at intracavitary upper of dry powder punishment in advance
Section and the lower section intracavitary positioned at vacuum suction.
Vacuum suction bottom of chamber portion is provided with sealing rubber cover.
The feed pipe and horizontal direction are in 30-45 °.
Filling head provided by the utility model for the filling air charging system of dry powder extinguisher, it is simple in sturcture, ingenious in design,
It is durable, by the way that pumping pipe fitting is arranged in vacuum suction chamber and opens up concora crush through-hole in dry powder punishment in advance top of chamber, realize negative
The rapid conversion that pressure suction and negative pressure release；Meanwhile cooperation makes dry powder is filling can open i.e. with the feed pipe for swinging closure plate
Stop；In addition, filling tube protrudes into bottle body, bottle mouth position can be trickled down to avoid powder, when seal plug open when, outside air into
It is intracavitary to enter dry powder punishment in advance, powder remaining in cavity can be all blown into bottle.By above-mentioned measure, filling essence is effectively increased
Degree and filling efficiency avoid the amount of labour caused by repeatedly doing over again and increase, alleviate labor intensity, improve site environment, save
About filling cost.

Specific embodiment
As shown in Figure 3,4, the filling head described in the utility model for the filling air charging system of dry powder extinguisher, including with
The vacuum suction chamber 1 of sealing bottle cooperation, uniformly distributed on the side wall of vacuum suction chamber 1 there are two be evacuated pipe fitting Q.Vacuum suction chamber
1 top is provided with dry powder punishment in advance chamber 2, and concora crush through-hole is offered at the top of dry powder punishment in advance chamber 2, and concora crush through-hole and aciculiform lifting cylinder drive
Dynamic seal plug 3 matches.It is communicated with that 30-45 ° of inclination is arranged upwards and to extend to chamber intracorporal on 2 side wall of dry powder punishment in advance chamber
Feed pipe 4,4 end of feed pipe are provided with swing closure plate 5 of the hinge point at the top of tube wall, and 2 bottom of dry powder punishment in advance chamber, which is provided with, wears
It crosses vacuum suction chamber 1 and extends to the intracorporal filling tube 6 of bottle.For the ease of maintenance, vacuum suction chamber 1 and dry powder punishment in advance chamber 2 are
The connected split type structure of bolt, correspondingly, filling tube 6 divide for the upper section in dry powder punishment in advance chamber 2 and are located at vacuum suction
Lower section in chamber 1.For the ease of blanking, the material bottom of chamber portion of dry powder punishment in advance chamber 2 is throat structure.In order to increase air-tightness, vacuum
1 bottom of pumping chamber is equipped with the sealing rubber cover 7 directly contacted with bottle body.
In use, sealing rubber cover 7 is engaged with sealing bottle, then to vacuum suction chamber 1 and the dry powder communicated therewith
Punishment in advance chamber 2, fire extinguisher bottle carry out vacuum pumping, and after the vacuum degree for reaching setting, it is automatic under vacuum to swing closure plate 5
It opens, dry powder enters dry powder punishment in advance chamber 2 by feed pipe 4, and injects in fire extinguisher bottle body through filling tube 6, and dry powder injection rate reaches
When mark, the automatically controlled inlet valve of feed pipe 4 is automatically closed, and stops charging, then move up seal plug 3, by dry powder punishment in advance chamber 2 and greatly
Gas connection, when outside air enters dry powder punishment in advance chamber 2 from concora crush through-hole, the powder of 2 bottom remnants of dry powder punishment in advance chamber can be complete
Portion is blown into bottle body, after preventing filling head and bottle body from disengaging, material waste caused by this part powder is scattered and scene pollution.When
When dry powder punishment in advance 2 internal and external pressure balance of chamber, 5 automatic attaching of closure plate is swung on feed pipe 4.
