Below the working procedure of piston type natural gas line batch charger of the present invention is described, in order to further explain the principle of piston type natural gas line batch charger.
In conjunction with Fig. 1 to Fig. 5 the working principle of piston type natural gas line batch charger is described.The work of batch charger of the present invention comprises gets the material process and the process that feeds intake.Fig. 1 has shown that piston type natural gas line batch charger is in holding state.Get the material process referring to figs. 2 and 3, the process that feeds intake is with reference to figure 4 and Fig. 5.
Begin to enter into the material process of getting from holding state, drive motor drives leading screw 12 rotations, and drive the beginning of second piston 9 and carry out straight line motion (right-to-left motion in Fig. 1) to first piston 18, and pull bar 6 moves to first piston 18 under the drive of second piston 9 together, because the movable end of pull bar 6 is to wear in first rob support 4, and be to flexibly connect between the first piston 18, therefore, this moment, first piston 18 remained static.After second piston 9 touches first piston 18, continue to drive second piston 9 to left movement, promote first piston 18 moved further same with it simultaneously, up to the outside that first piston 18 is pushed into feed pipe 5 tube walls, namely state shown in Figure 2 then drives stop motion.Then, drive motor begins antiport, drive leading screw 12 backward rotation, make 9 beginnings of second piston oppositely mobile, right direction in figure moves, move to the outside of feed pipe 5 tube walls (with the feed pipe tube wall of first piston 18 opposite sides) always, state as shown in Figure 3, drive motor quits work.In this process, first piston 18 keeps motionless, forms a space between first piston 18 and second piston 9 thereby make.Sorbing material (charge bar) 24 enters in the space that forms between first piston 18 and second piston 9 from feed pipe 5.Wherein, in order to guarantee at second piston 9 in the direction moving process that leaves first piston 18, first piston 8 keeps motionless, can form a charging space between first piston 18 and second piston 9, should make between drawing article (upright moving nut 3) and pull bar and second rob support, 11 fixed ends apart from S2 greater than the minimum range S1 between first rob support 4 and second rob support 11, distance when this first rob support 4 and minimum range between second rob support 11 are the two-phase corresponding end phase contact of first piston 18 and second piston 9, and should apart from S2 with apart from the difference of the S1 diameter more than or equal to feed pipe 5.Diameter according to the feed pipe 5 that is connected with first piston cylinder body 17, can adjust the position of drawing article (adjusting pulling nut 3), thereby adjust the size in the above-mentioned charging space that forms between first piston 18 and second piston 9, to adapt to the sorbing material (charge bar) 24 of throwing in different length or different amounts.That is, when forming above-mentioned charging space between first piston 18 and second piston 9 at that time, pulling nut 3 against or near first rob support 4.
Next enter into the process of feeding intake, start drive motor and continue counterrotating, it is oppositely mobile that leading screw 12 drives second piston 9, namely move to the right direction shown in the figure, under the drive of pull bar 6, make first piston 18 same moved further, then first piston 18 and 9 clampings of second piston sorbing material (charge bar) 24 and are moved right, arrive position shown in Figure 4 always, sorbing material (charge bar) 24 enters into the container 7 that feeds intake, under the gravity effect, sorbing material 24 disengaging first pistons 18 and second piston 9 enter into natural gas line from the narrow end of the container 7 that feeds intake.After sorbing material 24 was thrown in, first piston 18 and second piston 9 reached state shown in Figure 5, and namely holding state shown in Figure 1 is waited for feeding intake next time.So far, finish the process of feeding intake.
Get in the material process above-mentioned, because the two-phase corresponding end of second piston 9 and first piston 18 is mutual contacts to be adjacent to and to run to feed pipe 5 places, there is not the gap between second piston 9 and the first piston 18, also just can not carry rock gas enters feed pipe 5, solve the problem of natural gas leaking in the process of feeding intake, realized purpose of the present invention.Above-mentioned is that the present invention will be described for example with solid-state sorbing material, the present invention is applicable to too and throws in liquid sorbing material that in said process, feed pipe 5 injects liquid sorbing material and gets final product, owing to be provided with the 3rd seal 16, liquid sorbing material can not revealed yet.
Above-mentioned get the material process and feed intake only drive 9 motions of second piston by leading screw 12 in the process, and by the single-way linkage mechanism between first piston 18 and second piston 9, can realize unidirectional pulling first piston 18, itself and second piston are linked.First piston 18 motion left in the drawings realizes that by second piston, 9 ejection first pistons 18 first piston 18 is to left movement; Second piston 9 is by the unidirectional pulling first piston 18 of described single-way linkage mechanism, realizes first piston 18 moving right in the drawings.Because the existence of described single-way linkage mechanism only arranges a drive motor and can drive first piston 18 and second piston 9, has reduced cost, has simplified control program.From accompanying drawing, can see, be provided with two cover single-way linkage mechanisms, make stressed more even.Owing to be provided with the 3rd seal 16, first seal 19 and second seal, 21, one sides and avoided natural gas leaking, the opposing party and feasiblely only have piston need bear big pressure, other movable parts needn't bear big pressure, have reduced manufacture cost.
Another optimized technical scheme is, described first piston 18 is connected with an arrestment mechanism, and accurate to guarantee first piston 18 movement position in getting material and the process that feeds intake, after the drive motor stop motion, first piston 18 can stop synchronously.Particular type and the structure of described arrestment mechanism are not limited, as long as it is just passable that first piston 18 and second piston 9 are stopped synchronously, below only give one example and describe.
In a specific embodiment,, be provided with first piston brake rod 13, one cover magnetic brakes 1 in the left side of first piston locating column 14 and act on first piston brake rod 13, in order to brake first piston 18 to shown in Figure 6 as Fig. 1.Magnetic brake 1 preferred electromagnetic brake.
Fig. 6 has shown the concrete structure of above-mentioned electromagnetic brake, comprising: electromagnet 25, brake spring 26, a pair of brake slipper 27 and magnetic drive part 28.Tractive magnetic drive part 28 after electromagnet 25 magnetizes, magnetic drive part 28 makes a pair of brake slipper 27 clamp first piston brake rods 13 by a series of linkage mechanisms, and then braking first piston 18.One end of brake spring 26 is connected to magnetic drive part 28, and the other end is connected on the electromagnet 25 place pedestals.After electromagnet 25 degaussings, make the elastic force tractive magnetic drive part 28 of brake spring 26, so just make brake slipper 27 still clamping first piston brake rod 13.Because the elastic force of brake spring 26 is less than the pulling force of electromagnet 25, so brake slipper 27 can not make 13 stop motions of first piston brake rod, can only delay the motion of first piston brake rod 13 by increasing surface friction drag.The existence of this surface friction drag can prevent from producing between first piston 18 and second piston 9 unnecessary gap.This is particularly important in getting the material process, and this surface friction drag makes second piston, 9 total energys keep ejection first piston 18, makes the gap can not occur between first piston 18 and second piston 9, also just can not take the rock gas in the container 7 that feeds intake to feed pipe 5 places.By adopting the brake spring 26 of different model, can adjust the frictional force between brake slipper 27 and the first piston brake rod 13, but this surface friction drag is significantly smaller than in the process of feeding intake, the motive force of 3 pairs of first pistons 18 of pulling nut, to guarantee under the drive of second piston 9, first piston 18 can move right synchronously with it, and operation feeds intake.
Technological scheme of the present invention can be thrown in sorbing material automatically by simple automatic control program is set, and adorns sorbing material under the normal pressure, saves labour turnover.
The above only is the schematic embodiment of the present invention, is not in order to limit scope of the present invention.Any those skilled in the art, the equivalent variations of doing under the prerequisite that does not break away from design of the present invention and principle and modification all should belong to the scope of protection of the invention.And need to prove, each constituent element of the present invention is not limited in above-mentioned overall applicability, each technical characteristics of describing in the specification of the present invention can select one to adopt or select the multinomial use that combines separately according to actual needs, therefore, other combination relevant with this case inventive point and concrete the application have been contained in the present invention in the nature of things.
