Description
Technical field
The utility model belongs to metallurgy sintered pelletizing industry dust strength and carries explosion-proof technology field, the particularly explosion-proof self-closing blowdown valve in a kind of powder pneumatic transporting powder feeding dirt storehouse.
Background technology
At metallurgy sintered pelletizing industry powder, adopt strength to carry at present very general, if the materials such as dedusting ash, quick lime, light dolomite, amargosite in agglomerates of sintered pellets factory are because its fine size, moisture are low, the characteristic of easy airborne dust, should not adopt sealing-tape machine to carry, and strength is carried and to be had route flexible arrangement, the advantage such as clean is widely adopted in agglomerates of sintered pellets factory.
Granular material generally adopts pneumatic conveying mode to be transported in corresponding sealing ore storage bin, and ore storage bin top arranges that bag-type dust collector gathers dust and pressure release, but in actual production due to technology imperfection, very easily cause cloth bag to stop up.The pressure that seals ore storage bin in process of pneumatic transmission, along with the rising of material level increases gradually, when ore storage bin pressure acquires a certain degree, has just produced swollen storehouse, and dust is emerged in a large number, and contaminated environment damages production operator body and mind simultaneously.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, install, maintenance is convenient, the safe and reliable explosion-proof self-closing pressure release valve device in powder pneumatic transporting powder feeding dirt storehouse, eliminates the phenomenon in swollen storehouse in powder process of pneumatic transmission, improves working environment.
For achieving the above object, the utility model adopts following technical proposals:
The explosion-proof self-closing blowdown valve in powder pneumatic transporting powder feeding dirt of the present utility model storehouse, comprise cylindrical valve body, valve gap, rotary handle and the valve rod being connected with rotary handle, it is characterized in that: described outside, cylindrical valve body upper end has the outside thread being threaded with valve gap, the lower end of cylindrical valve body is provided with the butt flange matching with powder pneumatic transporting powder feeding dirt storehouse warehouse interface, described powder pneumatic transporting powder feeding dirt storehouse warehouse interface is fixedly connected with bolt by packing seal with butt flange, bottom in cylindrical valve body is also provided with shoulder, on described valve gap, have breather hole, in described valve rod lower end, be provided with ball-crown body, lower end at described rotary handle is provided with metallic gasket, between cylindrical valve body and valve gap, be provided with dust-filtering nest plate, between described metallic gasket and ball-crown body, be provided with spring, the shoulder that described ball-crown body and cylindrical valve body bottom arrange is abutted against.
On described shoulder, be provided with rubber sheet gasketing.
The utility model has the advantages that:
1) when sealing ore storage bin pressure is excessive, promote to have the ball-crown body releasing pressure automatically of directional tagging valve rod, when pressure is normal, under the thrust of spring, automatically reset, ore storage bin is resealed, thereby improved production environment, protected sealing dust storehouse body, saved warehouse maintenance labour power;
2) this self-closing blowdown valve ball-crown body thrust can realize by adjusting pressure release valve taper knob, simple to operate, the taper knob of hollow plays good directional tagging to having the ball-crown body of directional tagging valve rod when doing longitudinal travel simultaneously, has guaranteed the parking position accuracy of ball-crown body;
3) self-closing blowdown valve primary member adopts and to be threaded, simple in structure, and installation and maintenance are convenient, and without power supply, reusable have certain economy;
4) this self-closing blowdown valve, with dust-filtering nest plate, carries out dust-filtering to pressure release gas out, thereby further reaches the object of improving working environment, has extended the use of blowdown valve.
Accompanying drawing explanation
Fig. 1 is the structural representation of self-closing blowdown valve.
Fig. 2 is framing member 3 dust-filtering nest plate birds-eye vieies.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
As Fig. 1, shown in 2, the explosion-proof self-closing blowdown valve in the utility model powder pneumatic transporting powder feeding dirt storehouse, comprise cylindrical valve body 5, valve gap 2, rotary handle 1 and the valve rod 13 being connected with rotary handle 1, it is characterized in that: described cylindrical valve body 5 outsides, upper end have the outside thread being threaded with valve gap 2, the lower end of cylindrical valve body 5 is provided with the butt flange 9 matching with powder pneumatic transporting powder feeding dirt storehouse warehouse interface 11, described powder pneumatic transporting powder feeding dirt storehouse warehouse interface 11 is fixedly connected with bolt by packing seal 10 with butt flange 9, bottom in cylindrical valve body 5 is also provided with shoulder 8, on described valve gap 2, have breather hole 14, in described valve rod 13 lower ends, be provided with ball-crown body 7, in the lower end of described rotary handle 1, be provided with metallic gasket 4, between cylindrical valve body 5 and valve gap 2, establish dust-filtering nest plate 3, between described metallic gasket 3 and ball-crown body 7, be provided with spring 6, described ball-crown body 7 is abutted against with the shoulder 8 that cylindrical valve body 5 bottoms arrange.When powder pneumatic transporting powder feeding dirt storehouse warehouse pressure is excessive, promotion has the automatic up pressure release of ball-crown body of directional tagging valve rod, when pressure is normal, under the thrust of spring, automatically reset, ore storage bin is resealed, thereby improved production environment, protect sealing dust storehouse body, saved warehouse maintenance labour power;
The utility model passes through the elastic force of rotation regulating handle adjustable springs 6, and then regulates ball-crown body 7 thrusts with valve rod 13,
In order to guarantee the leak tightness of blowdown valve, the utility model is provided with rubber sheet gasketing 12 on described shoulder 8.Rubber sheet gasketing 12 sticks on the shoulder 8 of valve body 5.
The pressure that seals ore storage bin in process of pneumatic transmission is along with the rising of material level increases gradually, when acquiring a certain degree, ore storage bin pressure promotes the ball-crown body 7 under valve rod, gas with dust enters pressure release valve body first after the purification of dust-filtering nest plate 3, final process enters atmosphere with the valve gap 2 of breather hole, thereby reach the object of pressure release, purified environment, the ball-crown body 7 after the pressure release of ore storage bin pressure under valve rod resets under the thrust of spring 6, reseals ore storage bin simultaneously.
