Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The embodiment specifically describes an unsaturated polyester resin conveying device, please refer to fig. 1 in detail, which mainly includes an input pipeline a1 and a conveying pipeline, wherein the input pipeline a1 is used for inputting liquid, that is, unsaturated polyester resin, and the conveying pipeline is used for conveying unsaturated polyester resin, and then outputting the unsaturated polyester resin to a designated position for filling. Specifically, a solenoid valve a7 is installed at the outlet end of the conveying pipeline to control timely filling, and most particularly, a step metering conveyor is connected between the input pipeline a1 and the conveying pipeline, the step metering conveyor comprises a plurality of measuring devices a2 with different capacity sizes, each measuring device a2 has a corresponding nominal capacity, and the measuring devices a2 are arranged in sequence from large to small and are connected in sequence, for example, 50L, 45L and 42L or 10L, 8L, 3L, 1L, 0.5L and 0.2L. Each gauge a2 has an overflow port on one side to which an overflow trough a4 is connected, as shown in fig. 2-3, the overflow trough a4 may be a triangular trough-like structure, and the capacity value of the corresponding gauge a2 at each overflow port (i.e., the horizontal dot-dash line in each gauge a2 in fig. 1) is its own nominal capacity. When the device is specifically installed, two adjacent measuring devices a2 are communicated through an overflow groove a4, so that liquid in the previous measuring device a2 can overflow into the next measuring device a2, a discharge pipeline a5 is connected to the bottom of each measuring device a2 so as to completely discharge liquid accumulated inside, then all discharge pipelines a5 are connected with a common pipeline a6, electromagnetic valves a7 are installed on the common pipeline a6, and the liquid with the nominal volume is discharged in a centralized manner, so that the set and standard volume is obtained.
In actual manufacture, the outlet end of the input pipe a1 is positioned at the upper left of the largest gauge a2 so as to input the unsaturated polyester resin. It is also critical that at least one partition a3 is provided in each of the meters a2 of the unsaturated polyester resin transfer apparatus, the partitions a3 are preferably arranged in parallel with each other, and the outlet ends of the overflow grooves a4 of the larger meters a2 of the two adjacent meters a2 are located between the corresponding two adjacent partitions a 3. In addition, the upper end of the partition plate a3 is flush with the open end of the gauge a2, the lower end of the partition plate a 3578 has a gap with the inner bottom of the gauge a2, and the partition plate a3 enables the liquid on the two sides of the partition plate a3 to only pass through the gap, so that the design can ensure that the unsaturated polyester resin overflowing from the previous gauge a2 cannot greatly oscillate when entering the next gauge a2, so that the liquid level of the unsaturated polyester resin in the gauge a2 is not stable, and the unsaturated polyester resin spills out rather than naturally overflows the overflow groove a4, which is particularly important. Of course, in order to improve the prevention of the occurrence of the erroneous overflow, it is preferable that the distance between the partition plate a3 and the inner side wall of the container a2 on the side of the overflow groove a4 is not more than one third of the inner diameter of the container a 2. Besides, a plurality of horizontal plates can be fixedly connected to the inner side wall of the gauge a2 on one side of the overflow groove a4, all the horizontal plates are radially arranged along the gauge a2, and the free ends of the horizontal plates are not contacted with the partition plate a 3; and most preferably, the horizontal plates are arranged at intervals along the height direction of the gauge a2, and the horizontal plates are long on the length side from top to bottom. In addition, it can also be designed that a grid plate a13 is horizontally arranged in the inner part of the side of the partition plate a3 close to the larger gauge a2 in each gauge a2, and especially a grid plate a13 is designed for the gauge a2 at the input pipeline, so that the unsaturated polyester resin can be uniformly and slowly permeated, and the overflow impact can be reduced; or actually, the overflow bath a4 is set to be optimal as close as possible to the liquid level of the gauge a 2. These designs can maintain the liquid level at the overflow groove a4 as smoothly as possible without generating a great oscillation when the unsaturated polyester resin in the previous container a2 overflows into the next container a 2.
In order to realize that the unsaturated polyester resin can be intensively conveyed and discharged when reaching the set conveying capacity, the embodiment specially designs a triggering device, as shown in fig. 4, the triggering device comprises a seat groove a8, a sliding cup body a9, an elastic element a10, a movable contact a11 and a fixed contact a12, the seat groove a8 is fixedly connected below an overflow groove a4 of the minimum gauge a2, a cylindrical smooth cavity is arranged in the seat groove a 3538, the sliding cup body a9 is supported by the elastic element a10 and is installed in the seat groove a8 in a sliding fit manner, and the outlet end of the overflow groove a4 of the minimum gauge a2 is positioned above the sliding cup body a 9. The moving contact a11 is fixed on the outer bottom of the sliding cup body a9, and the fixed contact a12 is fixed on the inner bottom of the seat groove a 8. In actual use, the smallest gauge a2 starts overflowing to indicate that all the liquid in the gauge a2 is full and reaches a nominal value, at this time, the smallest gauge a2 overflows, so that the sliding cup body a9 slides down due to the accumulated liquid, so that the movable contact a11 is contacted with the fixed contact a12, and the movable contact and the fixed contact control the on-off circuit of the electromagnetic valve a7, so that the normally closed control valve is immediately opened, and the unsaturated polyester resin in the gauge a2 is intensively conveyed and discharged.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
