Reclaiming process is entered into from holding state, drive motor drives leading screw 12 to rotate, and drive the second piston 9 to start to carry out straight line motion (right-to-left motion in FIG) to first piston 18, and pull bar 6 moves to first piston 18 together under the drive of the second piston 9, movable end due to pull bar 6 wears in the first rob support 4, with be flexibly connected between first piston 18, therefore, now first piston 18 remains static.After the second piston 9 touches first piston 18, continue driving second piston 9 to left movement, promote first piston 18 and its synchronizing moving, until first piston 18 to be pushed into the outside of feed pipe 5 tube wall, namely state shown in Fig. 2, then drive stop motion simultaneously.Then, drive motor starts antiport, leading screw 12 is driven to rotate backward, the second piston 9 is made to start reverse movement, to the right direction motion in figure, move to the outside of feed pipe 5 tube wall (with the feed pipe tube wall of first piston 18 opposite side), state as shown in Figure 3, drive motor quits work always.In this process, first piston 18 keeps motionless, thus makes to form a space between first piston 18 and the second piston 9.Sorbing material (charge bar) 24 enters into from feed pipe 5 in the space that formed between first piston 18 and the second piston 9.Wherein, in order to ensure at the second piston 9 in the direction moving process leaving first piston 18, first piston 8 keeps motionless, a charging space can be formed between first piston 18 and the second piston 9, drawing article (pulling nut 3) and the distance S2 between pull bar and the second rob support 11 fixed end should be made to be greater than minimum range S1 between the first rob support 4 and the second rob support 11, distance when minimum range between this first rob support 4 with the second rob support 11 is the two-phase corresponding end phase contact of first piston 18 and the second piston 9, and this distance S2 is more than or equal to the diameter of feed pipe 5 with the difference of distance S1.According to the diameter of the feed pipe 5 be connected with first piston cylinder body 17, the position of drawing article (adjustment pulls nut 3) can be adjusted, thus the size in the above-mentioned charging space formed between adjustment first piston 18 and the second piston 9, to adapt to the sorbing material (charge bar) 24 throwing in different length or different amount.That is, when forming above-mentioned charging space between first piston 18 and the second piston 9 at that time, pull nut 3 against or close to the first rob support 4.
Next the process of feeding intake is entered into, start drive motor and continue counterrotating, leading screw 12 drives the second piston 9 oppositely movement, namely to the right direction motion shown in figure, under the drive of pull bar 6, make first piston 18 synchronizing moving, then first piston 18 and the second piston 9 hold sorbing material (charge bar) 24 and move right, arrive position shown in Fig. 4 always, sorbing material (charge bar) 24 enters into the container 7 that feeds intake, under gravity, sorbing material 24 departs from first piston 18 and the second piston 9 enters into natural gas line from the narrow end of the container 7 that feeds intake.After sorbing material 24 is thrown in, first piston 18 and the second piston 9 reach state shown in Fig. 5, i.e. holding state shown in Fig. 1, wait for and feeding intake next time.So far, the process of feeding intake is completed.
In above-mentioned reclaiming process, two-phase corresponding end due to the second piston 9 and first piston 18 is that mutual contact is adjacent to and runs to feed pipe 5 place, gap is there is not between second piston 9 and first piston 18, also would not carry rock gas and enter feed pipe 5, solve the problem of natural gas leaking in the process of feeding intake, achieve object of the present invention.It is above-mentioned that for solid adsorbant material, the present invention will be described, the present invention is applicable to throw in liquid sorbing material too, and in above process, feed pipe 5 injects liquid sorbing material, owing to being provided with the 3rd seal 16, liquid sorbing material also can not be revealed.
At above-mentioned reclaiming process with feed intake in process and only drive the second piston 9 to move by leading screw 12, and by the single-way linkage mechanism between first piston 18 and the second piston 9, can realize unidirectionally pulling first piston 18, itself and the second piston are linked.First piston 18 motion left in the drawings, realizes first piston 18 to left movement by the second piston 9 ejection first piston 18; Second piston 9 pulls first piston 18 by described single-way linkage mechanism is unidirectional, realizes first piston 18 moving right in the drawings.Due to the existence of described single-way linkage mechanism, a drive motor is only set and can drives first piston 18 and the second piston 9, reduce cost, simplify control program.Can see from accompanying drawing, be provided with Liang Tao single-way linkage mechanism, make stressed evenly.Owing to being provided with the 3rd seal 16, first seal 19 and the second seal 21, avoid natural gas leaking on the one hand, make only have piston need bear large pressure on the other hand, other movable parts need not bear large pressure, reduce manufacture cost.
Another preferred technological scheme is, described first piston 18 is connected with an arrestment mechanism, and accurate to ensure first piston 18 movement position in feeding and the process that feeds intake, after drive motor stop motion, first piston 18 can synchronously stop.Particular type and the structure of described arrestment mechanism are not limited, as long as can make, first piston 18 is synchronous with the second piston 9 to be stopped just passable, only gives one example below and is described.
In a specific embodiment, as shown in Figures 1 to 6, be provided with first piston brake rod 13 in the left side of first piston locating column 14, a set of magnetic brake 1 acts on first piston brake rod 13, in order to brake first piston 18.Magnetic brake 1 is electromagnetic brake preferably.
Fig. 6 shows the concrete structure of above-mentioned electromagnetic brake, comprising: electromagnet 25, brake spring 26, a pair brake slipper 27 and magnetic drive part 28.Tractive magnetic drive part 28 after electromagnet 25 magnetizes, magnetic drive part 28 makes a pair brake slipper 27 clamp first piston brake rod 13 by a series of linkage mechanism, 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 pedestal of electromagnet 25 place.When after electromagnet 25 degaussing, make the elastic force tractive magnetic drive part 28 of brake spring 26, so just make brake slipper 27 still hold first piston brake rod 13.Elastic force due to brake spring 26 is less than the pulling force of electromagnet 25, and therefore brake slipper 27 can not make first piston brake rod 13 stop motion, by increasing surface friction drag, can only delay the motion of first piston brake rod 13.The existence of this surface friction drag can prevent from producing unnecessary gap between first piston 18 and the second piston 9.This is particularly important in reclaiming process, and this surface friction drag makes the second piston 9 total energy keep ejection first piston 18, makes to there will not be gap between first piston 18 and the second piston 9, also the rock gas fed intake in container 7 would not be taken to feed pipe 5 place.By adopting the brake spring 26 of different model, the frictional force between brake slipper 27 and first piston brake rod 13 can be adjusted, but this surface friction drag should be made to be significantly smaller than in the process of feeding intake, pull the motive force of nut 3 pairs of first pistons 18, to ensure under the drive of the second piston 9, first piston 18 synchronously can move right with it, carries out feeding intake operation.
Technological scheme of the present invention can throw in sorbing material automatically by arranging simple automatic control program, fills sorbing material, save labour turnover under normal pressure.
The foregoing is only the schematic embodiment of the present invention, and be not used to limit scope of the present invention.Any those skilled in the art, the equivalent variations done under the prerequisite not departing from design of the present invention and principle and amendment, all should belong to the scope of protection of the invention.And it should be noted that, each constituent element of the present invention is not limited in above-mentioned overall applicability, the each technical characteristics described in specification of the present invention can select one to adopt separately or select the multinomial use that combines according to actual needs, therefore, the present invention covers other relevant with this case inventive point in the nature of things and combines and embody rule.
