Abstract
The invention relates to an explosion-proof discharge valve. The explosion-proof discharge valve comprises a metering hopper, wherein a feeding port is formed in the upper end of the metering hopper, a discharging port is formed in the lower end of the metering hopper, an anti-static punched felt bag is arranged in the position, corresponding to the discharging port, in the metering hopper, one end of a push rod is fixedly connected to the upper end of the anti-static punched felt bag, and the other end of the push rod is connected with a power device for making the push rod move vertically; the outer layer of the anti-static punched felt bag is coated with a Teflon coating layer, and the diameter of the anti-static punched felt bag is larger than the caliber of the discharging port. The explosion-proof discharge valve has anti-static performance, inadhesion performance, flame retardance, abrasion resistance and corrosion resistance, the adhesion, static electricity and explosion problems in the discharging process are effectively solved, and the explosion-proof discharge valve is simple, convenient and fast to use, economical and practical.
Description
Technical field
The invention belongs to device for transporting objects, be specifically related to a kind of explosion-proof discharge valve.
Background technology
Discharge valve is widely used in commercial production as material conveying equipment, and in inflammable and explosive industries such as firecrackers, chemical industry, oil and medicine, due to the particularity of industry raw material, runs into the static factor such as flower or extraneous igniting of setting fire, and very easily causes exploding and fire.
Existing discharge valve adopts star-shaped discharge valve more, and this kind of equipment is realized discharging by driven by motor blade rotary, and its shortcoming is easily between storeroom, material and blade, to produce frictional static at material Umklapp process, thereby is not suitable for the discharging of inflammable and explosive raw material.Discharging in explosion-proof field produces static for preventing material friction, is generally manual cleaning, wastes time and energy, and has greatly reduced work efficiency.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of explosion-proof discharge valve that prevents static, prevents material adhesion.
The technical scheme that the present invention solves its technical matters employing is:
A kind of explosion-proof discharge valve, it comprises weighing hopper, described weighing hopper upper end is provided with inlet point, described weighing hopper lower end is provided with discharging opening, in weighing hopper inside, with discharging opening correspondence position be provided with electrostatic prevention Needled mat bag, described electrostatic prevention Needled mat bag upper end is fixedly connected with one end of push rod, and the other end of described push rod connects the engine installation that makes push rod up-and-down movement; Described electrostatic prevention Needled mat bag skin is coated with teflon coating, and described electrostatic prevention Needled mat bag diameter is greater than the bore of discharging opening.
Further improve, described teflon coating material is polytetrafluoroethylene.
Further improve, described electrostatic prevention Needled mat bag inclusion is sand.
Further improve, described electrostatic prevention Needled mat bag adopts terylene needled filtering felt through implantable conductive yarn or sneaks into conductive fiber and forms.
Further improve, described weighing hopper is back taper.
Further improve, described engine installation is cylinder or hydraulic actuating cylinder.
Beneficial effect of the present invention is: by making the engine installation of push rod up-and-down movement drive the motion of electrostatic prevention Needled mat bag to realize opening and sealing of discharging opening, in electrostatic prevention Needled mat bag motion process, owing to adopting the anti-adhesion material of electrostatic prevention, simultaneously in electrostatic prevention Needled mat bag surface coating one deck teflon coating, strengthen anti-static effect, avoid electrostatic prevention Needled mat bag and material contact friction to produce static, avoid material that on fire and blast occurs, sand also can effectively avoid producing static as inclusion, has improved the safety performance of producing; Weighing hopper, for back taper designs, contributes to moving downward of material, reduces the sticky wall of material.The present invention has antistatic properties, non-adhesion property, flame resistance, abrasion test and corrosion stability, efficiently solves sizing, static and Explosion-Proof in blowing process, simple and convenient, economical and practical.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 weighing hopper, 2 engine installations, 3 push rods, 4 electrostatic prevention Needled mat bags, 5 inlet points, 6 discharging openings, 7 teflon coatings, 8 sands.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is further described.
As shown in Figure 1, the present embodiment comprises weighing hopper 1, described weighing hopper 1 upper end is provided with inlet point 5, described weighing hopper 1 lower end is provided with discharging opening 6, in weighing hopper 1 inside, with discharging opening 6 correspondence positions be provided with electrostatic prevention Needled mat bag 4, described electrostatic prevention Needled mat bag 4 upper ends are fixedly connected with one end of push rod 3, and the other end of described push rod 3 connects the engine installation 2 that makes push rod 3 up-and-down movements;
Described electrostatic prevention Needled mat bag 4 skins are coated with teflon coating 7, and described electrostatic prevention Needled mat bag 4 diameters are greater than the bore of discharging opening 6.
Described teflon coating 7 materials are polytetrafluoroethylene.
Described electrostatic prevention Needled mat bag 4 inclusion are sand 8.
Described electrostatic prevention Needled mat bag 4 adopts terylene needled filtering felt through implantable conductive yarn or sneaks into conductive fiber and forms.
Described weighing hopper 1 is back taper.
Described engine installation 2 is cylinder or hydraulic actuating cylinder.
The loading of sand 8 is to be full of electrostatic prevention Needled mat bag 4 and can to block discharging opening 6 as good.
The specific works process of the present embodiment is: when material is delivered to weighing hopper 1 by apparatus for feeding, cylinders retract, drives electrostatic prevention Needled mat bag 4 upward movements by push rod 3, and now discharging opening 6 is opened, and starts discharging.After discharging completes, cylinder stretches out, and promotes electrostatic prevention Needled mat bag 4 by push rod 3, and discharging opening 6 is sealed.Owing to adopting electrostatic prevention Needled mat bag 4, and in the outer teflon coated coating 7 of electrostatic prevention Needled mat bag 4, effectively avoid the generation of material static in discharge process, improved the safety of producing.
