Abstract
The invention discloses an electric unloading valve for a double-ended screw blade. The electric unloading valve comprises a rotor impeller 1, a shell 2, a main shaft 3, a bearing 4, left and right end covers 5, a maze sealing part 6, an upper flange hole 7, a lower flange hole 8, a speed reducer 9, a motor 10. The electric unloading vale is characterized in that the double-ended spiral blades 1-1 on the rotor impeller 1 are double-ended spiral blades which are dropped into a gap between the double-ended spiral blades 1-1 on the rotor impeller 1 through dead load and are unloaded on the lower part along with the rotation of the double-ended spiral blades 1-1. The electric unloading valve has the beneficial effect that the unloading amount is great under the same motor power condition in comparison with the conventional electric unloading valve, the sealing part adopts a maze sealing part so as to achieve a relatively good gas locking function.
Description
Technical field
The present invention relates to a kind of electronic discharge valve of twin-feed spiral blade, belong to the mechanical equipment technical field of air-transport system.
Background technology
Discharge valve is commonly used in the discharge valve as feed bin in air-transport system, dust pelletizing system, and it is specially adapted to dust, small particles material, deeply by environmental protection, metallurgy, chemical industry, grain, cement, build the road, the engineering item of the industrial trade such as drying equipment uses on a selective basis.The overall efficacy of the quality well determining result of use of its sealing property and dedusting, Geldart-D particle.In the actual use of current discharge valve due to its blade design and the bad lock airway dysfunction of dust pelletizing system, air-transport system that causes of sealing property bad, make system there is Leakage Gas; The electronic discharge valve power of large-sized silo is relatively high simultaneously, cost is uneconomic.
Summary of the invention
The object of the invention is to improve the deficiencies in the prior art, a kind of blade design and favorable sealing property, the electronic discharge valve of a kind of twin-feed spiral blade that discharge quantity is large are provided.The object of the present invention is achieved like this: the present invention relates to a kind of material discharge valve, particularly relate to a kind of electronic discharge valve of twin-feed spiral blade, comprise rotor wheel 1, housing 2, main shaft 3, bearing 4, left and right end cap 5, labyrinth seal 6, upper flange mouth 7, lower flange mouth 8, retarder 9, electrical motor 10 forms, it is characterized in that the twin-feed spiral blade 1-1 on its rotor wheel 1 of the electronic discharge valve of a kind of twin-feed spiral blade is twin-feed spiral blade, fall in the space between the twin-feed spiral blade 1-1 be filled on rotor wheel 1 by deadweight, draw off in bottom with the rotation of twin-feed spiral blade 1-1.Described rotor wheel 1 has rotor twin-feed spiral blade 1-1, its end lining poly-vinyl fluoride labyrinth seal 6, and adjustable double-head helicallobe 1-1 end after wearing and tearing, make it still keep in touch with housing 2 inside, have air locking energy.Described labyrinth seal 6 is poly-vinyl fluoride sealing bands, can ensure that twin-feed spiral blade 1-1 end and housing 2 inwall have good contact.Described upper flange mouth 4 is square or circular.Described lower flange mouth 5 is square or circular.
the invention has the beneficial effects as follows:
1, compared with traditional electronic discharge valve, under the condition of same motor power, discharge quantity is large;
2, sealing member adopts labyrinth seal, and lock airway dysfunction is better.
Accompanying drawing explanation
the electronic discharge valve detail drawing of a kind of twin-feed spiral of Fig. 1, Fig. 2 blade:
1-rotor wheel 1-1 impeller twin-feed spiral blade 2-housing 3-main shaft 4-bearing about 5-end cap 6-labyrinth seal 7-upper flange mouth 8-lower flange mouth 9-retarder 10-electrical motor.
Detailed description of the invention
each portion composition of the electronic discharge valve of embodiment 1 one kinds of twin-feed spiral blades and effect:
A kind of electronic discharge valve of twin-feed spiral blade comprises rotor wheel 1, housing 2, main shaft 3, bearing 4, left and right end cap 5, labyrinth seal 6, upper flange mouth 7, lower flange mouth 8, retarder 9, electrical motor 10 form, it is characterized in that the twin-feed spiral blade 1-1 on its rotor wheel 1 of the electronic discharge valve of a kind of twin-feed spiral blade is twin-feed spiral blade, fall by deadweight in the space between the twin-feed spiral blade 1-1 be filled on rotor wheel 1, draw off in bottom with the rotation of twin-feed spiral blade 1-1.Described rotor wheel 1 has rotor twin-feed spiral blade 1-1, its end lining poly-vinyl fluoride labyrinth seal 6, and adjustable double-head helicallobe 1-1 end after wearing and tearing, make it still keep in touch with housing 2 inside, have air locking energy.Described labyrinth seal 6 is poly-vinyl fluoride sealing bands, can ensure that twin-feed spiral blade 1-1 end and housing 2 inwall have good contact.Described upper flange mouth 4 is square or circular.Described lower flange mouth 5 is square or circular.
the core value of the electronic discharge valve of embodiment 2 one kinds of twin-feed spiral blades:
The helical pitch of twin-feed spiral blade is single-screw 2 times, therefore its lower materials quantitative is 2 times of single thread blade when equivalent motor power, increases discharge quantity.
