The beneficial effects of the utility model are that novel structure has simple structure in the transmission course, the security is good, and environmental pollution is little, carries degree of automation high, and convenient operation switches in a flexible way, and it is convenient to maintain, the fault rate is low, applicablely effectively prevents air conveying's discontinuous work in various complicated topography occasions, has improved bulk cargo air conveying's production efficiency greatly.
Description
Technical field:
This utility model relates to industrial air conveying failture evacuation field, is specially a kind of pneumatic conveyer anti-block apparatus.
Background technology:
Air conveying having been widely used, air conveying working media is air, and discharge is convenient, free from environmental pollution, good economy performance, the viscosity of air is little simultaneously, it is simple to long-distance sand transport, and energy loss is little, thus air conveying reaction is fast, safeguards simple, there is not media protection and supplementary question, easy for installation；Secondly air conveying working environment adaptability is good, it is allowed to operating temperature range width, and air conveying also have overload protective function.
But the air conveying transfer passage that must provide for sealing in bulk cargo (such as grain, ore in sand form, cement, flour, coal etc.) transmitting procedure, the most existing air conveying in often there is plugging phenomenon.After blocking, can not export continuously in the material short time, blower motor live load excess, greatly damage motor performance, and had a strong impact on production efficiency.
Utility model content:
For solving the drawbacks described above of prior art, this utility model provides a kind of pneumatic conveyer anti-block apparatus, described a kind of pneumatic conveyer anti-block apparatus includes valve plate, rubber slab, sponge plate, joint pin, cylinder, bearing, strength passage forms, described valve plate one end is installed with the preferable rubber slab of sealing effectiveness, can be rotated around strength passage by joint pin, the other end passes through joint pin and cylinders, described rubber slab is installed above dust-proof sponge plate, described strength passage is close to by rubber slab simultaneously, described cylinder is connected with described bearing by joint pin, described bearing is fixed on described strength passage.
Described a kind of pneumatic conveyer anti-block apparatus is slider-crank mechanism, cylinder is slide block, valve plate is crank, the rotation of the flexible promotion valve plate of cylinder, after valve plate rotates, rubber slab and sponge plate also sway in synchrony, so that rubber slab and strength passage move generation relative movement, air and then entrance strength passage so that strength passage air pressure changes, the bulk cargo of blocking is scattered, and solves plugging phenomenon.
Further, described strength passage leaving circular aperture, a length of 4-9mm of hole diameter, a length of 6-15mm of described rubber slab, a width of 5-12mm, for ensureing sealing effectiveness, rubber slab overall dimensions should be greater than strength channel opening size.
Further, described valve plate is metal plate muscle Welding Structure, and Metal plate is carbon element steel alloy, and panel beating thickness is 3-7mm, uses argon-are welding technology.
Further, the normal operation circumstances temperature of described cylinder is-5～70 DEG C, and operating pressure is 0.1～100Mpa, and movement velocity scope is 50～500mm/, uses five mouthfuls two or five mouthfuls of three serial formula reversal valves.
The beneficial effects of the utility model are novel structures, having simple in construction in transmitting procedure, safety is good, and environmental pollution is little, conveying automaticity is high, easy to operate, switching is flexibly, easy to maintenance, failure rate is low, it is applicable to various complicated landform occasion, effectively prevents air conveying discontinuous work, substantially increase the production efficiency that bulk cargo is air conveying.
Accompanying drawing illustrates:
Fig. 1 is a kind of pneumatic conveyer anti-block apparatus structural representation described in the utility model；
Fig. 2 is the profile of a kind of pneumatic conveyer anti-block apparatus described in the utility model；
Detailed description of the invention:
Described a kind of pneumatic conveyer anti-block apparatus includes that valve plate 3, rubber slab 4, sponge plate 5, joint pin 6, cylinder 7, bearing 8, strength passage 9 form, described valve plate 3 one end is installed with the preferable rubber slab of sealing effectiveness 4, can be rotated around strength passage 9 by joint pin 6, the other end is connected with cylinder 7 by joint pin 6, described rubber slab 4 is installed above dust-proof sponge plate 5, described strength passage 9 is close to by rubber slab 4 simultaneously, described cylinder 7 is connected with described bearing 8 by joint pin 6, and described bearing 8 is fixed on described strength passage 9.
Circular aperture is left on strength passage 9, the a length of 4-9mm of hole diameter, when there is not blocking in pneumatic conveyer, the circular aperture left on strength passage 9 is blocked by rubber slab 4, extraneous air is not had to enter strength passage 9, now cylinder 7 is in elongation state so that the valve plate 3 being connected with cylinder 7 has the most just been tightly pressed on strength passage 9 near strength passage 9, the rubber slab 4 being arranged on valve plate 3；
When there is blocking in pneumatic conveyer, cylinder 7 is in contraction state, make the valve plate 3 being connected with cylinder 7, relative to strength passage 9, rotating of certain angle occur, the rubber slab 4 being arranged on valve plate 3 the most just there occurs certain displacement with strength passage 9, so that extraneous air enters strength passage 9 by the aperture on strength passage 9, provides source of the gas for blower fan, reduce blower motor load, the bulk cargo of blocking, not by absorption affinity, will drop at blocking rapidly, thus alleviate feed blocking problem.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described; skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications; in the range of these changes and improvements both fall within claimed this utility model, this utility model claims scope and is defined by appending claims and equivalent thereof.
