Description
Technical field
The utility model relates to a kind of feeder, relates in particular to a kind of high-pressure rotary feeder.
Background technology
Rotary feeder is the visual plant that in air-transport system, is used for the quantitative discharging of solid powder/particle material, mainly through the Spin Control of impeller and the flow of distribution material.Because the material that strength is carried need be airtight and have in the system of pressure and transmit, thus under normal situation about using, the pressure release of can not leaking gas of the binding site of each part of rotary feeder, material can not flow in the bearing, and bearing oil can not infiltrate material.
Traditional rotary feeder; Air leakage when being used in the air-transport system is mainly from two aspects, and a part is included in the air leakage rate between the blade when being the rotor rotation, and another part is the amount of air that leaks through the gap between casing and the blade; The size of air leakage is directly proportional with rotary feeder difference of pressure up and down; The amount of air that leaks is many more, and the Volumetric efficiency of rotor is just low more, when serious even can't feed.Otherwise then Volumetric efficiency increases.
Continuous progress and development along with industrial technology; The high pressure air-transport system obtains application more and more widely in fields such as chemical industry, food, mining; According to the information of grasping; At present, the high-pressure rotary feeder market in the domestic air-transport system is captured by foreign nationality enterprises such as Germany, the U.S., Holland basically.The high-pressure rotary feeder of prior art the hermetically-sealed construction weak effect, its sealing mechanism is the amount of air that leaks through the gap between casing and the blade through reducing, its hermetically-sealed construction is a filler; The radial compensation of gland packing need provide lasting axle pressure; In order to reach enough axle pressures, often need arrange a considerable amount of springs, cause complex structure; Install loaded down with trivial detailsly, its sealing also is easy to lose efficacy.
Summary of the invention
The purpose of the utility model is: in order to overcome the deficiency of prior art, the utility model provides a kind of high-pressure rotary feeder of simple in structure, good sealing effect.
To achieve these goals, the technical scheme below the utility model has adopted:
A kind of high-pressure rotary feeder comprises housing, end cap and is arranged on turning cylinder and the impeller in the housing that described housing is connected with end cap; Described end cap is provided with the gas lock hole; The two ends of described turning cylinder are equipped with end cap respectively, and the two ends of turning cylinder are provided with bearing, and bearing is arranged between end cap and the turning cylinder; Described impeller is connected with turning cylinder; Turning cylinder impeller under the driving of motor is rotated, and is provided with the first road poted assemblies between the edge at described impeller two ends and the inner walls, and the impeller two ends are near being provided with the second road poted assemblies between turning cylinder place and the end cap; Be provided with the three seals assembly between said turning cylinder and the end cap; Described three seals assembly comprises driving packing element and non-driving packing element, and described driving packing element comprises first packing element and second packing element that is arranged on the turning cylinder drive end, and the described second road poted assemblies, first packing element, bearing and second packing element set gradually along turning cylinder from inside to outside.
As preferably, the described first road poted assemblies comprises the working groove that is arranged on the inner walls, is provided with Glais ring in the working groove.After adopting above-mentioned preferred version, Glais ring simple in structure, convenient processing and installation, resistance is little, applies axle pressure owing to need not device, with traditional packing seal structure elder generation ratio, has saved space and material.Glais ring generally is made up of seal ring and rubber elastomer, has the effect of two way seal.
As preferably, described first packing element and second packing element are Oil sealing assembly, and described non-driving packing element is an Oil sealing assembly.After adopting above-mentioned preferred version, adopt Oil sealing assembly can make the rotation of turning cylinder more flexible.
As preferably, setting is sealed and matched between described end cap and the housing.After adopting above-mentioned preferred version, make the high pressure of the utility model select the sealing effectiveness of dress feeder better.
As preferably, the described second road poted assemblies is a felt.After adopting above-mentioned preferred version, process more convenient.
The high-pressure rotary feeder of the utility model is provided with multi-sealed assembly; When the rotary feeder according to the utility model is used for delivery system quantitatively during discharging; At first feed pressurized air through the gas lock mouth, pressure gets final product a little more than material conveying pipe pressure, then start-up system; Material gets into rotary feeder; This moment is because the gaseous tension between the first road seal ring and the three seals circle is higher than system pressure, and transmits in rotary feeder through the first road seal ring, so rotary feeder inside possibly be prevented to the powder that leak in the external world; And the existence of the second road seal ring, played the effect of protecting the second road poted assemblies, and also can stop powder to leak to the bearing end.Play the effect of seal lubrication grease in the three seals assembly near the oil sealing of impeller, can prevent that the lubricating grease between the oil sealing from penetrating into system pipeline.
The setting of the first road poted assemblies has reduced the amount of air that leaks through the gap between casing and the blade, has improved the filling rate of impeller, compares with traditional packing seal; Its hermetically-sealed construction is simple, need not the axle pressure device, does not creep during startup; Resistance is little, no sticking phenomenon, and wear ability and dimensional stability are good; Groove is simple, needs axial length short.
The high-pressure rotary feeder of the utility model has reduced the amount of air that leaks through the gap between casing and the blade, good sealing effect, simultaneously; The utility model device simple in structure need not the axle pressure device, and resistance was little when impeller rotated along with rotating shaft; Wear ability is good, has improved service life.
