Abstract
The utility model discloses an air-control balancing device and belongs to the technical field of balancing devices. The air-control balancing device comprises a three-way pipe, butterfly breather valves, air passage actuators and a connecting flange, wherein the butterfly breather valves are arranged on the three-way pipe in the position close to the through hole A end and in the position close to the through hole B end, the butterfly breather valves are connected with the air passage actuators respectively, and the connecting flange is arranged on the three-way pipe in the position close to the through hole C end. The utility model has the benefits that the air-control balancing device is mounted on a metering bin or a main storage bin in a feeding system, which not only can reduce the differential pressure in the sealed metering bin, but also can reduce the pollution to the external air.
Description
Technical field
The utility model relates to a kind of control air balancing device, belongs to the balancing device technical field.
Background technology
Existing feeding system generally comprises feed system, measuring chute and delivery system, and material enters measuring chute from feed system, again in delivery system reaches designating apparatus.Because of measuring chute is the leak free container, when material enters measuring chute, when measuring chute enters delivery system, in measuring chute, be easy to generate pressure reduction again, cause the material in the measuring chute can't free fall, cause measuring inaccurate.In order to reduce the pressure reduction in the measuring chute, generally can above measuring chute, offer a mouth, air outside mouthful directly enters measuring chute thus, can effectively reduce the pressure reduction in the measuring chute, guarantees that the material in the measuring chute can free fall, improves measuring accuracy.Material in the part but this method also comes with some shortcomings, measuring chute from then on mouth is gone out, and foul air has also caused the waste of material simultaneously.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of control air balancing device, and it is installed on the major ingredient storehouse in measuring chute and the feed system, both can reduce the pressure reduction in the airtight container measuring chute, also can reduce the pollution to extraneous air.
To achieve these goals, the technical solution adopted in the utility model is: a kind of control air balancing device, comprise three-way pipe, butterfly scavenge valve, gas circuit actr and butt flange, position near through hole A end and through hole B end on three-way pipe is respectively equipped with a butterfly scavenge valve, each butterfly scavenge valve all connects a gas circuit actr, is provided with butt flange on three-way pipe and near the position of through hole C end.
Wherein, through hole B on the three-way pipe and the angle between the through hole C are 45 degree.
The beneficial effects of the utility model are: it is installed on the major ingredient storehouse in measuring chute and the feed system, both can have reduced the pressure reduction in the airtight container measuring chute, also can reduce the pollution to extraneous air.
Description of drawings
Fig. 1 is a structural representation of the present utility model
View when Fig. 2 uses for the utility model
Among the figure: 1, three-way pipe, 2, the butterfly scavenge valve, 3, the gas circuit actr, 4, butt flange, 5, the major ingredient storehouse, 6, measuring chute, 11, through hole A, 12, through hole B, 13, through hole C, 61, air extractor vent.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises three-way pipe 1, butterfly scavenge valve 2, gas circuit actr 3 and butt flange 4, position near through hole A11 end and through hole B12 end on three-way pipe 1 is respectively equipped with a butterfly scavenge valve 2, each butterfly scavenge valve 2 all connects a gas circuit actr 3, is provided with butt flange 4 on three-way pipe 1 and near the position of through hole C13 end.
Wherein, the angle between through hole B12 and the through hole C13 is 45 degree on the three-way pipe 1; The material of three-way pipe 1 is 16 manganese.
As shown in Figure 2, during use, this device is installed on the major ingredient storehouse 5 in measuring chute 6 and the feed system, and through hole C13 is connected with major ingredient storehouse 5, the air extractor vent 61 that through hole B12 passes through on the measuring chute 6 is connected with measuring chute 6.Set a higher limit and a lower limit for measuring chute 6, be used for controlling the switch of two butterfly scavenge valves 2 on the three-way pipe 1, thereby control the pressure reduction of measuring chute 6, and then improve whole feeding system.
When the material in the measuring chute 6 is lower than lower limit, system begins to feed in raw material in measuring chute 6, the connected butterfly scavenge valve 2 of gas circuit actr 3 controls that is positioned at through hole C13 place this moment makes through hole C13 sealing, the connected butterfly scavenge valve 2 of gas circuit actr 3 controls that is positioned at through hole A11 place is simultaneously opened through hole A11, air outside via through holes A11 via through holes B12 enters measuring chute 6, can reduce the pressure reduction in the measuring chute, make the material that enters measuring chute 6 from major ingredient storehouse 5 can free fall to the bottom of measuring chute 6;
When the material in the measuring chute 6 reaches higher limit, measuring chute 6 beginning blankings, the connected butterfly scavenge valve 2 of gas circuit actr 3 controls that is positioned at through hole C13 place this moment is opened through hole C13, the connected butterfly scavenge valve 2 of gas circuit actr 3 controls that is positioned at through hole A11 place simultaneously makes through hole A11 sealing, the pressure reduction and the air extractor vent 61 of material powder on measuring chute 6 that produce in the measuring chute 6, through hole B12, through hole C13, enter the major ingredient storehouse again, reduced the pollution of air.
