The device comprises a feed inlet and a discharge opening, and is characterized in that an annular air chamber is arranged between the feed inlet and the discharge opening, upper flanges are arranged around the upper part of the annular air chamber, lower flanges are arranged around the lower part of the annular air chamber, the upper flanges and the lower flanges are fixed through bolts, compressed air pipes are respectively arranged on two sides of the annular air chamber, and a Venturi jet pipe is arranged below the discharge opening; an air chamber sealing ring is arranged between each lower flange and the annular air chamber; an conical surface annular gap is formed between the annular air chamber and each air chamber sealing ring; the angle of the conical surface annular gap between the annular air chamber and each air chamber sealing ring is 60 degrees; the air pressure input by the compressed air pipes is between 0.2 to 1.0 MPa. The annular air-locking flow-aiding device disclosed by the invention has the advantages of simple and compact structure, good air locking effect, and further capability of increasing the feeding speed.
Description
Technical field
The present invention relates to a kind of ring-like lock wind flow-aiding device, be mainly used in the lock wind on powder conveying equipment.
Background technology
During powdery material pneumatic is carried, conventionally use airlock, at present in known airlock as, the equipment such as lock air pump (spiral pump), air valve, these equipment investments are larger, need power, later maintenance is also larger, when flow is greater than 3t/h (taking coal dust as example), lock wind effect is comparatively desirable, and investment is comparatively to one's profit with output ratio; But in the time that flow is less than 3t/h (taking coal dust as example), adopt traditional lock wind devices, lock wind effect is poor, and investment is smaller with output.
The current lock wind devices in low discharge powder conveying, general according to the principle of Venturi tube, make jet pipe, due to industry spot pipeline length, thickness difference, elbow is how many, in different size, the not equal many factors of delivery duct loss of pressure, is difficult to the lock wind effect that reaches desirable in on-the-spot use.
Summary of the invention
Technical matters to be solved by this invention be to provide a kind of simple and compact for structure, lock wind is effective, can improve the ring-like lock wind of the one flow-aiding device of blanking velocity simultaneously.
Technical matters to be solved by this invention realizes by the following technical solutions.
A kind of ring-like lock wind flow-aiding device, comprise inlet point and discharging opening, it is characterized in that: between described inlet point and discharging opening, be provided with ring-shaped air chamber, described ring-shaped air chamber top surrounding is provided with upper flange, its below surrounding is provided with lower flange, between described upper flange and lower flange, be bolted, described ring-shaped air chamber both sides are respectively equipped with a compressed gas tracheae, and described discharging opening below is provided with Venturi jet pipe.
Between described lower flange and ring-shaped air chamber, be provided with air chamber seal ring.
Between described ring-shaped air chamber and air chamber seal ring, form conical surface circular clearance.
Between described ring-shaped air chamber and air chamber seal ring, conical surface annular clearance angle degree is 60 °.
The air pressure of described compressed gas tracheae input is between 0.2-1.0MPa.
The invention has the beneficial effects as follows: due to ring-shaped air chamber and the tapered gap of air chamber seal ring inwall, by the compressed gas tracheae at ring-shaped air chamber two ends, air after extraneous 0.2-1.0Mpa compression can be transported to ring-shaped air chamber inside, the high speed and high pressure compression ring that air-flow forms when forming conical surface circular clearance between ring-shaped air chamber and air chamber seal ring, keep out the wind that returns of Venturi jet pipe, granular material can flow in Venturi jet pipe by discharging opening smoothly; This apparatus structure is simply compact, lock wind is effective, and the zone of negative pressure that inlet point forms simultaneously contributes to the whereabouts of viscous material.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1,
A kind of ring-like lock wind flow-aiding device, comprise inlet point 1 and discharging opening 2, between inlet point 1 and discharging opening 2, be provided with ring-shaped air chamber 3, ring-shaped air chamber 3 top surroundings are provided with upper flange 4, its below surrounding is provided with lower flange 5, fixing by bolt 6 between upper flange 4 and lower flange 5, ring-shaped air chamber 3 both sides are respectively equipped with a compressed gas tracheae 7, and discharging opening 2 belows are provided with Venturi jet pipe 8.Between lower flange 5 and ring-shaped air chamber 3, be provided with air chamber seal ring 9.Between ring-shaped air chamber 3 and air chamber seal ring 9, form conical surface circular clearance.Between ring-shaped air chamber 3 and air chamber seal ring 9, conical surface annular clearance angle degree is 60 °.The air pressure that compressed gas tracheae 7 is inputted is at 0.2-1.0MPa.
Granular material is fallen by inlet point 1 under Action of Gravity Field, if can freely let out and drop down onto discharging opening 2 without returning wind (locking wind good) material.Because Venturi jet pipe 8 is locked wind poor effect, cause returning in a large number wind, granular material cannot fall, by ring-shaped air chamber 3 and air chamber seal ring 9 inwalls into a cone shape, in the time that compressed gas tracheae 7 passes into the pressure gas of 0.2-2.0MPa, pressurized air into a cone shape time, forms the vane of high-voltage high-speed with air chamber seal ring 9 inwalls by ring-shaped air chamber 3, vane speed is now exceedingly fast, the high wind that returns that can keep out Venturi jet pipe 8 of pressure; Meanwhile, this high-voltage high-speed vane drives inlet point 1 place's Air Flow, and the zone of negative pressure that inlet point forms contributes to the whereabouts of viscous material.
More than show and described groundwork of the present invention and principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
