Abstract
The utility model discloses a multi-stage automatic control speed regulating gas supply device used in the positive-pressure conveying article system. A plurality of gas supply executive elements (4) provided with different diameters and different pressures are combined in the parallel connection method, and thus, the specification is simplified. The utility model can be widely applicable to the positive-pressure conveying article system with various complex conditions such as the far and the near distance and the high and the low climbing slope. The utility model has the advantages of energy saving, lower noise, vibration isolation and safety guarantee.
Description
The utility model relates to a kind of gas feeder of pneumatic transmission sample, belongs to the technical field of compressed air delivery.
Between smeltery and laboratory, for carrying sample fast, standing closed pipeline system is a power with the pressurized air, the sample box is come and gone carry, and can replace the heavy work of artificial sample presentation like this.By plumbing system the branch of two-tube and single tube is arranged, pressing force mode branch has malleation and negative pressure.
In positive pressure system, to carry far and near or the climbing height for satisfying, design will be adopted different gas feeders.In the big system of distance, the gradient, should adopt the gas feeder of atm number; In the system that distance is near, the gradient is little or straight, just can adopt the gas feeder of little tolerance.Must make the gas feeder of plurality of specifications like this, thereby increase the complexity of manufacturing.Sample box running velocity is different in each pipeline section requirement in addition, thereby air demand also should have difference.In a system, its two ends promptly send and receiver section, and speed is suitable slow, and air demand should be less, during when climbing or by the bend section, enough air demands should be arranged.But the present gas feeder of producing can not need the required air demand of increase and decrease by operation.Thereby,, not only cause energy dissipation, but also produce a series of problems such as noise, vibration and safety because air demand is excessive at the system two ends.Both at home and abroad to these problems, all fail to solve at present.
The purpose of this utility model is to provide a kind of gas feeder of multi-stage self controlling speed governing.Not only simplify specification, can be widely used in far and near, the just malleation sample presentation system of various complex conditions of climbing of distance; And on energy savings, reduction noise, elimination vibration and guaranteeing safely, remarkable result is arranged all.
The utility model can be realized in the following manner: the size of setting each power element air feed latus rectum earlier, how much pressure of setting each latus rectum then respectively is to control air demand, again according to the characteristics of delivery system, change existing single air feed power element, be a plurality of air feed power elements, the air feed power element of different latus rectums is made up.Be parameter with speed and distance in addition, making software is in the input electrical control cubicles.During operation, by programming control, allow the air feed power element work of little latus rectum earlier in transmission moment of delivery section, the slow start of sample box is then carried the sample box with normal latus rectum, allows the air feed of little latus rectum hold element again and quits work.When to climbing or bend section when complicated, start the air feed power element of one or several little latus rectum different pressures more automatically, the sample box is able to speedup pass through after, little latus rectum air feed power element stops automatically.To receiver section, the program control air feed power element of closing normal latus rectum and starting little latus rectum steadily arrives sample box low speed.Whole process is finished automatically, thereby reaches the purpose of automatic control multistep speed regulation.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a basic block diagram of the present utility model.
The utility model takes mode in parallel to be formed as shown in Figure 1 by the air feed power element of a plurality of different latus rectum different pressures.1 is that compressed-air actuated input channel, 2 is that flow control valve, 4 is that air feed power element, 5 is the pressurized air delivery piping for connecting pipeline, 3 among the figure.By the characteristics of delivery system, be parameter with distance in addition, in the making software input electrical control cubicles with speed.During operation, open steam supply valve by programming control, pressurized air promptly by pipeline 1 input, work by the air feed power element of the little latus rectum of programmed instruction, then pressurized air is through flow control valve 3, air feed power element 4, and pipeline 5 air feed, because tolerance makes the sample box slowly move less.During to the section of climbing, Automatic Program starts the air feed power element of big latus rectum, and the sample box passes through Gao Po under the promotion of atm number.When the super km of fed distance, will drop into more air feed power element one by one by distance, increase gas flow, to remedy the pressure loss in the way, guarantee lasting thrust to the sample box.During to receiver section, some air feed power elements are closed in program control instruction, make the sample box of high-speed cruising, realize low cruise and steady whereabouts.The noise that sample box and receiving device bump is produced is reduced to gratifying degree.
Claims (2)
1, a kind of malleation sample presentation system that is used for, by the gas feeder that pressurized air input pipe (1) connection pipeline (2) flow control valve (3) air feed power element (4) and pressurized air delivery piping (5) are formed, it is characterized in that taking mode in parallel to be combined the air feed power element (4) of the different latus rectum different pressures of a plurality of settings.
2, gas feeder according to claim 1 is taked programming control when it is characterized in that moving; Its software is with speed and apart from being parameter, the establishment back is imported in the electrical control cubicles.
