The specific embodiment
Describe the control cock that separates for the gas-solid mixing material according to of the present invention in detail with exemplary embodiment below with reference to accompanying drawings.
Fig. 1 is the scheme drawing that is used for according to an exemplary embodiment of the present invention the control cock of gas-solid mixing material separation.As shown in Figure 1, the control cock that is used for the separation of gas-solid mixing material of this exemplary embodiment comprises valve body 10, feed pipe 11, baffle plate 12, discharging opening 13 and actuating device, wherein, described feed pipe 11 is arranged in the valve body 10, and have inlet point 11a and a feed opening 11b, this feed opening 11b has the end face that is acute angle with horizontal direction, and the gas-solid mixing material can enter and arrive feed opening 11b from inlet point 11a under Action of Gravity Field; Baffle plate 12 is arranged on the inside of valve body 10 and has closed position and open stance; Actuating device is connected with baffle plate 12, and can control baffle plate 12 and be in described closed position or described open stance, is at baffle plate 12 in the situation of closed position, and the upper surface of baffle plate 12 can close applying with the end face of feed opening 11b, with closed this feed opening 11b; Be at baffle plate 12 in the situation of described open stance, the lower surface of baffle plate 12 can and the end face of described feed opening 11b between form pre-fixed gap, described pre-fixed gap can be piled up the solid material of predetermined altitude with entrap gas in the inside of feed pipe 11 by the solid material in guaranteeing the gas-solid mixing material in feed opening 11b whereabouts, namely block gas and do not allow gas pass through, realize that the gas-solid mixing material separates; Discharging opening 13 is arranged on the bottom of valve body 10 and is positioned at the below of baffle plate 12.
Wherein, valve body 10 is steel structure; Feed opening 11b has the end face that is acute angle with horizontal direction, when baffle plate 12 is positioned at closed position, the end face of the upper surface of baffle plate 12 and this feed opening 11b fits tightly with closed feed opening 11b, end face with certain degree of dip can make closure effect better, namely be conducive to better sealing, prevent gas leakage, simultaneously, when baffle plate 12 is positioned at open stance, solid material can glide fast along the upper surface of baffle plate 12, and the solid material that flows down can compile and in time enters next production link by discharging opening 13.Find that through test the end face of feed opening and vertical direction are 45 °～60 ° for best.Baffle plate 12 can for oblong, square, circle and the shape commonly used such as oval, as long as can block the feed opening 11b of feed pipe when baffle plate 12 is positioned at closed position, play the closing seam effect and get final product.For the better effects if that closure effect, gas-solid mixing material are separated, and prevent that air-flow is ganged up between the valve body upper and lower, take into account simultaneously the factors such as alerting ability that save material, guarantee baffle plate, baffle plate 12 can be made more bigger than the described end face of feed pipe 11, in one exemplary embodiment of the present invention, the free edge of baffle plate 12 to the excircle distance of the described end face of feed pipe 11 is 2～3mm.
Actuating device can comprise adapter shaft 21 and driver element 22, one end of this adapter shaft 21 and baffle plate 12 captive joints (for example can for welding, pin key is connected or the bolt connection), the other end of adapter shaft is connected with driver element 22, and driver element 22 can maybe can be realized for the weight 22a of manual regulation the automatically variable-frequency motor 22b of adjusting.When adopting variable-frequency motor, can first round sheet be set at an end of the drive link of variable-frequency motor 22b, the described other end of adapter shaft 21 be provided with cooperate with it second take turns sheet 21a.The gas-solid mixing material control cock of exemplary embodiment of the present can adopt switching frequency and the switching degree of driver element 22 regulating fenders 12 of automatic or manual, with speed or the throughput of control solid material by baffle plate 12.When adopting weight, by lever principle when weight of material surpasses weight, baffle plate 12 is opened so that solid material passes through, when weight of material is lower than weight, baffle plate 12 is closed, so the gas-solid mixing material control cock of exemplary embodiment of the present takes full advantage of the rotation that the gravity of material drives baffle plate 12, has saved the energy, simultaneously spent material shutoff realizes gas solid separation; When adopting variable-frequency motor to drive the switching of adapter shaft 21 realization baffle plates 12, thereby can adjust the on-off times adjustment solid material of valve body in 10 unit time by baffle plate 12 speed or throughput by adjusting the variable-frequency motor frequency.In addition, weight and variable-frequency motor can be used, and also can use separately.Can find out that the design of the gas-solid mixing material control cock of exemplary embodiment of the present has taken into full account the physics and chemistry performance in the gas-solid mixture course of conveying, in the requirement of guaranteeing to have satisfied in the quantitatively control situation flexible.
In order to prevent from leaking air between adapter shaft 21 and the valve body 10 Lou material, sealing unit can be set to guarantee the leak tightness of whole control cock, wherein, sealing unit can be realized for seal ring, plug etc. the hermetically-sealed construction commonly used of sealing function.
Further, refractory masses 14 can be set at the internal face of valve body, refractory masses 14 can adopt the wearing-proof refractory material that is fit to high-temperature gas and material, so that this regulator apply valve is in High Temperature Gas solid mixture material.
In addition, for the convenient control cock internal operation situation of observing, overhaul timely, can the maintenance hand hole 15 that be communicated with valve inner be set at valve body 10.
In one exemplary embodiment of the present invention, above-mentioned gas-solid mixing material control cock and cyclone preheater and reactor are supported the use, in cyclone preheater, with high-temperature flue gas (850～1100) solid material (500～700 high temperature ilmenite concentrates) is carried out preheating, with gas-solid mixing material control cock of the present invention the gas-solid mixing material is separated after the preheating, wherein, solid material enters reactor from discharging opening 13 continuously and stably, whole production process continous-stable, the good separating effect of gas-solid mixing material, solid material does not have in heaps falling, good sealing effect.In addition, the invention is not restricted to above-mentioned exemplary embodiment, can also be used for the conveying of high temperature (or normal temperature) solid material.
In sum, gas-solid mixing material control cock of the present invention has following advantage: simple in structure, applicable, it is little to take up room, and equipment investment is low; Realized that the gas-solid mixing material separates, and solid material can move continuously and stably; Both gone for high temperature (or normal temperature) gas-solid mixing material, also applicable to high temperature (or normal temperature) solid material; Can realize quantitative control, flexible material, have preferably sealing property, avoid gas leakage leakage material in the operational process.
