Description
Technical field
The present invention relates to a kind of discharge valve that is used for the air-transport system dosing of solid material, particularly a kind of inner casing leak free hanging type lock gas discharge valve.
Background technology
At present, the rotation device for discharging is adopted in the quantitative discharging of solid material usually in the air-transport system.The unsettled inner casing of representative type rotation discharge valve is mainly processed by metal casting or steel (sheet material) material, and has only a housing.Use the discharge valve of metal casting housing, load-bearing is big, but because himself is very heavy, the transportation, installation, maintenance difficulty.Use the discharge valve of sheet material housing, generally can only be used for the delivery system of light materials such as grain, plastics, if when being used for the bigger solid particle material discharging of proportion; The housing easy deformation; Cause with the gap of impeller inhomogeneously, cause leak tightness to reduce, increase power consumption; Impeller will be stuck when serious, can't move.
Because the material that strength is carried need be airtight and have in the system of pressure and transmit, thus to the air-tightness of discharge valve and delivery pressure require increasingly high.Can produce gas leakage in the rotation discharge valve operational process, comprise: the gas leakage that causes in (1) impeller rotary course; (2) gas leakage of the generation of the gap between blade and the housing.These all cause the discharge valve poor sealing performance, influence mass transport.And prior art often produces granule materials in actual use and is stuck in inlet point, influences load, damages impeller, bearing when serious, causes system shutdown.
In order to address the above problem, the inventor designs hanging type lock gas discharge valve, and this case produces thus.
Summary of the invention
The purpose of this invention is to provide a kind of hanging type lock gas discharge valve; It is in light weight, load-bearing property good, air-tightness is strong; Can stop the gas leakage in the inner casing; Improve the strength traffic capacity, reduce work energy consumption in the air-transport system, anti-ly get stuck, the blanking amount is big, easy to maintenance, long service life.
In order to achieve the above object, the present invention realizes through following technical scheme:
A kind of hanging type lock gas discharge valve adopts double hull configuration, comprises shell, inner casing, impeller, bearing seat, rotating shaft, transmission component, end cap, air guide port, anti-card structure and packing element; The tubular shell that coaxial shell that is nested and inner casing all are arranged horizontally, shell barrel upper end is provided with inlet point and is connected with hopper, and inlet point has anti-card structure; The below of inner casing is provided with the discharge valve outlet, and extends to housing exterior; Inner casing through being fixed on the shell inner bottom part the arc supporting pad and be axially fixed on the shell through end cap; The impeller of band side board is equipped with in the inner casing the inside, and the rotating shaft of impeller is fixed through bearing seat, and impeller is rotated under the driving of transmission component; Have air guide port on shell and the inner casing; Inner casing and shell are by end cap seal, and end cap is passed in the rotating shaft of impeller; Between shell and end cap, inner casing and end cap, end cap and rotating shaft, end cap and impeller side baffle plate, shell and supporting pad, inner casing and supporting pad, packing element is housed respectively.
Said shell adopts steel material to make, and inner casing adopts light materials such as sheet steel or engineering plastics to make.
Said inner casing end cap installed inside spring loaded floating seal ring or inflatable seal circle etc. can be changed after the wearing and tearing, and novel supra polymer engineering plastics HPF is adopted on the seal ring surface, can carry out radial seal with impeller side baffle plate place to end cap (inner casing).
The feeding mouth of said inner casing is equipped with the anti-card structure of triangle.
Said end cap is bearing on the bearing seat through bearing, is connected and sealed through lip-type packing of interior bag matrix type and end cap in rotating shaft and end cap contact surface.
Said arc supporting pad is provided with groove, and groove is embedded with the square-section rubber weather strip.
Said paddle shaft to the top tab have the waist hole is installed, adopt the fixed position, waist hole of tab regulate and the inner casing inwall between distance.
After adopting such scheme, the present invention has many beneficial effects:
One, the present invention adopts inside and outside shell to separate, and makes inside and outside shell select for use different materials to process as required, is steel casing like shell, and inner casing is sheet steel inner casing or engineering plastics inner casing etc., makes the discharge valve overall weight light, and load-bearing property is good; Even casing deformation, the gap between its inner casing and the blade also can keep stable status, and unaffected, air-tightness is better;
Two, the present invention adopts inside and outside shell to separate, and need not dismantle hopper at maintenance process, can directly impeller be taken out maintenance;
Three, the present invention is provided with packing element in each junction, and air-tightness is good, can improve the strength traffic capacity, and the work energy consumption is low;
Four, the present invention can adjust according to the operation pressure of system, and applicability is strong, and application is wide;
Five, feeding mouth of the present invention is equipped with anti-card structure, can stop the phenomenon that gets stuck;
Six, feeding intermittent time weak point of the present invention, stable performance, long service life, can be applicable to the quantitative discharging of various solid material delivery systems, comprise the bigger mineral of proportion such as coal.
