The specific embodiment
As previously mentioned, in the existing material transmitting device, all configure control cock on each arm of attached ventilation flue, when in conveying pipeline, having clogged up with material, realized the introducing of air-flow among the attached ventilation flue by the switch of corresponding control cock, to eliminate gradually occluded segment.But this material transmitting device needs a large amount of control cock, complicated integral structure, and cost is higher.
The inventor observes by long-term experiment and analyzes and recognizes when existing powder or granular solids material transmitting device occur to block, and the occluded segment in the conveying pipeline is often across a plurality of and attached ventilation flue's point of connection.And according to material properties and other transformation parameters, the rate of onset when entering pipeline such as pressure gas and feed rate etc., occluded segment length has difference.The effect of blocking in order to obtain dredging, when a whole set of conveying device fabrication is installed or is safeguarded, as when replacing attached ventilation flue, the arm that does not often need corresponding each contact point to provide an attached ventilation flue to tell, perhaps not need to each with pipeline that contact point links to each other on a control cock is provided.Through experiment test, when a control cock control to a plurality of point of connection, such as 2 to 4 point of connection, air-flow for seasonable, still can reach essentially identical obstruction eradicating efficacy.
As shown in Figure 1, a material transmission system comprises feed containers 1, is communicated with conveying pipeline 5 by rotovalve 3.Rotovalve 3 is driven by motor 4, establishes a switch valve 60 between the inlet point of its below and conveying pipeline 5.Conveying pipeline one end has admission port 9, links to each other with a compression gas suppling device by an air inlet pipe.Air inlet pipe is provided with reducing valve 6, and is being provided with boiler check valve 8 near admission port one end.
Material transmission system shown in Figure 1 comprises that also attached ventilation flue's 10, one ends are connected with a compression gas suppling device.This compression gas suppling device can be the device that shares with the compression gas suppling device of conveying pipeline, also can be a device independently.With the material transmitting device of conveying pipeline common compression gas supply device in, shared admission line partly also can be provided with a switch valve 7.Attached guide valve 10 has one or more arms 15, and arm 15 is communicated with at a plurality of point of connection P place with conveying pipeline 5.Arm 15 is provided with control cock V, by the air-flow input of the attached ventilation flue 10 of the switch controls of control cock V to conveying pipeline 5.
The V of control cock shown in Fig. 1 is the spring controlled valve with adjustable spring.This control cock has a default closed bias force, the difference of pressure of the static pressure that this bias force can be preset as the transmission pressure that substantially equals conveying pipeline 5 initiating terminals or attached ventilation flue 10 pressure at this point of connection P places, conveying pipeline 5 inherence when flowing through in the clear with point of connection P place corresponding to control cock when material in the importing conveying pipeline 5.Clogged up with material occurs in conveying pipeline, and during greater than this default bias force, control cock V opens to the difference of pressure of the air pressure in the air pressure at point of connection P place that should control cock V and the corresponding arm 15, removes clogged up with material in it thereby arm 15 interior air-flows enter conveying pipeline 5.When the unimpeded conveying of conveying pipeline 5 interior materials, above-mentioned difference of pressure is less than default closed bias force, and control cock V keeps closed condition.
Material transmitting device shown in Figure 2 is to shown in Figure 1 similar, and difference only is on the conveying pipeline 5 each point of connection P and control cock V by being connected in parallel a plurality of being in charge of, and is different from being connected in series shown in Fig. 1.
Fig. 3 has shown the another kind of embodiment of material transmitting device of the present utility model.Be with the difference of embodiment shown in Figure 1, control cock V is not spring controlled valve, but adopts a kind of control cock of automatic control.The position of closing on contact point in the conveying pipeline 5 arranges a pressure sensor, this pressure sensor is measured the pressure P t of relevant position in the conveying pipeline, and result of a measurement is sent to the control unit of control cock, this control unit is under the control of pre-set programs, according to the pressure measurements automatic switch control valve V that receives, thereby the conducting of controlling attached ventilation flue 10 and conveying pipeline 5 whether.
Fig. 4 is automatic controlling valve local structure schematic diagram in conveying pipeline and the air inlet pipe in the material transmitting device provided by the utility model.As shown in Figure 4, pressure gas admission port 9 places of conveying pipeline 5 can arrange an automatic controlling valve 11, and these both sides, automatic controlling valve 11 front and back are respectively arranged with two pressure information projector PT1 and PT2.Automatic controlling valve 11 can automatically adjust according to the signal of receiving from described two pressure information projector PT1 and PT2.For example when conveying is unobstructed, the measured force value of two pressure information projector PT1 and PT2 is substantially equal, and after automatic controlling valve 11 receives corresponding signal, keeps normally opening, thus the regular supply that keeps pressure gas.When occur blocking in the conveying pipeline or pipeline has when more obviously leaking gas, two pressure information projector PT1 and the measured force value of PT2 then may have than big difference, and after automatic controlling valve 11 receives corresponding signal, but valve-off, service personnel can be overhauled, perhaps strengthen degree of opening, assist to remove the obstruction in the conveying pipeline.
To establish automatic controlling valve 11 similar to pressure gas admission port 9 places of conveying pipeline 5, in attached ventilation flue's 10 entrance one automatic controlling valve 12 can be set also, and these both sides, automatic controlling valve 12 front and back are respectively arranged with two pressure information projector PT3 and PT4.Similar with the mode of operation of automatic controlling valve 11, automatic controlling valve 12 can automatically adjust according to the signal of receiving from described two pressure information projector PT3 and PT4.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
