Detailed description of the invention
Describe in detail with exemplary embodiment below with reference to accompanying drawings according to the control cock be separated for gas-solid mixing material of the present invention.
Fig. 1 is according to an exemplary embodiment of the present invention for the schematic diagram of the control cock of gas-solid mixing material separation.As shown in Figure 1, the control cock 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 valve body 10, and there is inlet point 11a and feed opening 11b, it is the end face of acute angle that this feed opening 11b has with horizontal direction, and gas-solid mixing material can enter from inlet point 11a and arrive feed opening 11b under gravity; 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, and when baffle plate 12 is in closed position, the upper surface of baffle plate 12 can close laminating with the end face of feed opening 11b, with closed this feed opening 11b; When baffle plate 12 is in 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 guaranteed while the solid material in gas-solid mixing material falls from feed opening 11b at the solid material of the building up inside predetermined altitude of feed pipe 11 with entrap gas, namely blocking gas does not allow gas pass through, and realizes gas-solid mixing material and is separated; 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; It is the end face of acute angle that feed opening 11b has with horizontal direction, when baffle plate 12 is positioned at closed position, the upper surface of baffle plate 12 and the end face of this feed opening 11b fit tightly with closed feed opening 11b, the end face with certain degree of dip can make closure effect better, namely better sealing is conducive to, 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 flowed down can collect and enter next production link by discharging opening 13 in time.Find through test, the end face of feed opening and vertical direction are 45 ° ~ 60 ° is the best.Baffle plate 12 can be oblong, square, circle and the conventional shape such as oval, as long as can block the feed opening 11b of feed pipe when baffle plate 12 is positioned at closed position, plays closing seam effect.In order to the better effects if making closure effect, gas-solid mixing material be separated, and prevent air-flow between valve body upper and lower from ganging up, take into account the factors such as the alerting ability of the baffle plate that saves material, ensures simultaneously, can by obtained more bigger than the described end face of feed pipe 11 for baffle plate 12, in one exemplary embodiment of the present invention, the free edge of baffle plate 12 is 2 ~ 3mm to the excircle distance of the described end face of feed pipe 11.
Actuating device can comprise adapter shaft 21 and driver element 22, one end of this adapter shaft 21 is fixedly connected with baffle plate 12 (such as can for welding, pin key is connected or bolt connects), the other end of adapter shaft is connected with driver element 22, and driver element 22 maybe can realize the automatic variable-frequency motor 22b regulated for the weight 22a of manual regulation.When adopting variable-frequency motor, first round sheet can be set on one end of the drive link of variable-frequency motor 22b, the described other end of adapter shaft 21 is provided with coordinate with it second take turns sheet 21a.The gas-solid mixing material control cock of exemplary embodiment of the present can adopt opening and closing frequency and the opening and closing degree of driver element 22 regulating fender 12 of automatic or manual, to control solid material by the speed of baffle plate 12 or throughput.When adopting weight, by lever principle when weight of material exceedes weight, baffle plate 12 is opened solid material is passed 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 makes full use of the rotation of the gravity drive baffle plate 12 of material, has saved the energy, spent material shutoff, realizes gas solid separation simultaneously; When adopting variable-frequency motor to drive adapter shaft 21 to realize the opening and closing of baffle plate 12, can the on-off times in valve body 10 unit time be adjusted by adjustment variable-frequency motor frequency thus adjust solid material by baffle plate 12 speed or throughput.In addition, weight and variable-frequency motor can be with the use of, also can be used alone.Can find out, the design of the gas-solid mixing material control cock of exemplary embodiment of the present has taken into full account the process based prediction model in gas-solid mixture course of conveying, is guaranteeing the requirement meeting flexible in fixing quantity situation.
Lou expecting to prevent from leaking air between adapter shaft 21 and valve body 10, can arrange sealing unit to ensure the leak tightness of whole control cock, wherein, sealing unit can be the conventional hermetically-sealed construction that seal ring, plug etc. can realize sealing function.
Further, can arrange refractory masses 14 on the internal face of valve body, refractory masses 14 can adopt the wearing-proof refractory material of applicable high-temperature gas and material, to make this regulator apply valve in high-temperature gas-solid mixed material.
In addition, conveniently observe control cock internal operation situation, overhaul timely, can the maintenance hand hole 15 be communicated with valve inner be set on 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), preheating is carried out to solid material (the high temperature ilmenite concentrates of 500 ~ 700), with gas-solid mixing material control cock of the present invention, gas-solid mixing material is separated after 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, the conveying of high temperature (or normal temperature) solid material can also be used for.
In sum, gas-solid mixing material control cock tool of the present invention has the following advantages: structure is simple, applicable, and take up room little, equipment investment is low; Achieve gas-solid mixing material to be separated, and solid material can run continuously and stably; Both go for high temperature (or normal temperature) gas-solid mixing material, be also applicable to high temperature (or normal temperature) solid material; Fixing quantity, flexible material can be realized, there is sealing property preferably, avoid gas leakage in operational process to leak material.
