[0031] The present invention will be further described below with reference to the embodiments and accompanying drawings:
[0032] like Figure 1-15 As shown, an automatic dewatering system for propellant mainly consists of a workbench 1, a propellant box 2, an extraction component, a clamping component, and a transfer component. Both the clamping and transfer components are mounted on the workbench, with the clamping component positioned above the extraction component. The extraction component is mounted on the transfer component. The extraction component primarily functions to vacuum-extract water from the propellant within the propellant box. The clamping component ensures the propellant box 2 is sealed, creating a vacuum extraction environment for the extraction component. The transfer component moves the propellant box 2 onto the extraction component. To facilitate dewatering of the propellant, the propellant box 2 is designed as a vertically continuous cylindrical structure, and a base support 3 is provided below the propellant box 2 to prevent leakage of propellant.
[0033] The extraction assembly includes an extraction base plate 4, on which a vacuum groove 4a with an open top is provided. To facilitate water extraction, a water-permeable plate 5 is provided on the extraction base plate 4 for water supply. Several water-permeable holes 5a are provided on the portion of the water-permeable plate 5 above the vacuum groove 4a. For drainage, a drain hole 4b communicating with the vacuum groove 4a and used to house pipes is provided at the bottom of the extraction base plate 4. To ensure sealing, a sealing groove 4c is provided on the extraction base plate at the outer edge of the upper end of the vacuum groove.
[0034] The specific structure of the transfer assembly includes a moving component for moving the extraction base plate 4 and the medicine box base 3, and a clamping component for fixing the medicine box 2. The moving component includes a first moving component 7, a second moving component 8, a third moving component 9, and a medicine box mounting plate 6. The extraction base plate 4 is set on the worktable 1 via the first moving component, and the first moving component 7 can move the extraction base plate 4 back and forth. A limiting block 13 is provided on the worktable 1 to limit the back and forth movement of the first moving component 7. An L-shaped block 13a is provided on the top of each limiting block 13, and the horizontal sections of the L-shaped blocks 13a on the front and rear sides face each other.
[0035] The medicine box mounting plate 6 is set on the extraction base plate 4 by the second moving component 8, and the second moving component 8 can drive the medicine box mounting plate 6 to move back and forth. The medicine box mounting plate 6 is located on the front side of the permeable plate 5. When the medicine box 2 with the medicine box base 3 is placed on the medicine box mounting plate 6, the bottom surface of the medicine box 2 is flush with the top surface of the permeable plate 5.
[0036] Clamping blocks 6a are provided on the left and right sides of the rear end of the medicine box mounting plate 6 to clamp the medicine box base 3. The third moving component 9 is located on the front side of the medicine box mounting plate 6 and is used to ensure that the medicine box base 3 is clamped by the clamping blocks 6a. When the medicine box moves to a position where it can be clamped by the clamping component, the clamping component operates. At this time, when the medicine box base is moved, the medicine box will not move, so the medicine box can be moved to the permeable plate for vacuum pumping.
[0037] The clamping assembly includes a clamping seat 10 disposed on the workbench 1, a clamping cylinder 11 disposed on the clamping seat 10, a clamping block 12 disposed on the telescopic end of the clamping cylinder 11, and clamping forks 12a disposed on both the front and rear sides of the clamping block 12 for clamping the medicine box 2, and an outwardly inclined guide slope disposed on the inner side of the end of the two clamping forks 12a away from the clamping block.
[0038] To prevent residual propellant at the bottom of the propellant box from clogging the permeable holes on the permeable plate when it moves on the permeable plate, a filter cloth cover is provided on the permeable plate 5. For easy installation of the filter cloth cover, a covering part 5b is provided at the front end of the permeable plate 5, and a filter cloth clamping assembly is provided at the rear end of the permeable plate 5 to maintain the filter cloth cover in a taut state. Since the covering part can be held against the rear end of the propellant box mounting plate, to further clamp the filter cloth cover, the lower front end of the covering part is set as a rearward inclined slope, and the corresponding rear end of the propellant box mounting plate is also set as a rearward inclined slope.
[0039] The filter cloth pressing assembly includes a tensioning cylinder 14 located on the rear side of the extraction base plate 4, a tensioning push plate 15 located at the output end of the tensioning cylinder 14, a gate-shaped filter cloth pressing strip 16 hinged on the tensioning push plate 15, and filter cloth pressing rollers 17 extending to the left and right on the rear side of the filter cloth pressing strip 16. Pressing roller grooves 5c extending to the left and right on the permeable plate 5 at the positions corresponding to the filter cloth pressing rollers 17.
[0040] To prevent the filter cloth pressure strip from tilting backward without external force, magnetic suction parts 15a are provided on both the left and right ends of the front side of the tensioning push plate 15. Correspondingly, magnetic elements 18 that can be magnetically attracted to the magnetic suction parts are provided on the left and right sides of the filter cloth pressure strip 16. In the initial state, the filter cloth pressure strip is pushed forward to rotate, so that the magnetic elements are attracted to the magnetic suction parts. When the tensioning cylinder moves downward, it can drive the filter cloth pressure roller to press down on the pressure roller groove, pressing the filter cloth cover covering the permeable plate. When it is necessary to collect the firing agent on the filter cloth cover, the tensioning cylinder pushes the filter cloth pressure roller upward, and at the same time moves the filter cloth pressure strip to rotate backward, and then the filter cloth cover can be removed.
[0041] The clamping assembly includes a gate-shaped clamping seat 19, which can be mounted on two clamping seats or directly on the worktable, offset to the left and right from the clamping seats. A pressure plate cylinder 20 is provided in the middle of the upper end of the clamping seat 19. A dewatering pressure plate 21 is provided at the output end of the pressure plate cylinder 20, located below the clamping seat 19. A dewatering pad 24 is provided below the dewatering pressure plate 21. When the medicine box is clamped by the clamping blocks, the pressure plate cylinder works, causing the dewatering pad to press on the medicine box, specifically the upper end of the medicine box.
[0042] A pressing flange 2a is provided at the upper end of the medicine box 2 to achieve a seal by pressing with a pressing component, and the distance between the bottom surface of the pressing flange and the top surface of the medicine box base is greater than the thickness of the locking fork. For easy handling, the medicine box base 3 is set as Type II, and a notch is provided on the rear side of the upper end of the medicine box base 3 to facilitate the placement of the medicine box, and weight reduction holes are provided on the left and right sides to facilitate manual movement. A contact part 3a is provided on the rear side of the lower end of the medicine box base 3 to press on the extraction component, that is, the rear side of the lower end of the medicine box base can extend backward, and when the medicine box mounting plate abuts against the permeable plate, the contact part is located above the permeable plate. A snap-fit flange can also be provided at the bottom of the medicine box, and a snap-fit groove matching the snap-fit flange and extending back and forth is provided on the inner bottom surface of the medicine box base. To ensure that the medicine box can be smoothly placed on the permeable plate, the rear side of the lower end of the medicine box is aligned with the rear side of the lower end of the medicine box base when placed.
[0043] A collection tank 1a for collecting water is provided on the workbench 1. The workbench 1 is set on the ground by a support frame 22. A partition 22a for placing a collection box 23 is provided on the support frame 22 below the workbench. A collection hole is provided vertically through the workbench 1 to allow water in the collection tank to flow into the collection box. The partition can also be used to place other components.
[0044] In this invention, the movement of the first, second, and third moving components is achieved using telescopic cylinders. Because the third moving component has a shorter moving distance, it, along with the pressure plate cylinder and the clamping cylinder, uses a double-extending rod telescopic cylinder. The first and second moving components, however, have longer moving distances, hence the use of telescopic cylinders. A guide rail slider assembly is also provided to ensure the straightness of the forward and backward movement. Both telescopic cylinders and double-extending rod telescopic cylinders are mounted on corresponding components via corresponding mounting bases.
[0045] To reduce the risk of spontaneous combustion of the propellant, the device is housed inside an explosion-proof chamber, while the vacuum pump for extracting the components is located outside the chamber. The control system for stopping and starting the entire device is also located outside the explosion-proof chamber. The entire device is shut down before personnel enter the chamber and only resumes operation after personnel have finished dispensing the propellant and left. To facilitate the pouring or placement of the propellant into the charging box, a dispensing station is provided on the workbench. Initially, the charging box with its base is placed on the dispensing station. Once the box is full of propellant, it is moved to the charging box mounting plate to await the next step. A leveling block with a handle is also provided to facilitate the smoothing of the propellant within the charging box.
[0046] To improve efficiency, two dewatering devices can be installed on the same workbench at intervals on the left and right, with the corresponding two drug dispensing stations set up adjacent to each other.
[0047] The work includes the following steps:
[0048] 1. Loading the propellant. Before personnel enter the explosion-proof room, the entire device is shut down. The propellant is poured into or placed in the propellant box located at the delivery station, ensuring it is spread evenly inside the box. The propellant box, with its base support, is then placed on the mounting plate. After leaving the explosion-proof room, the device is started. Due to the high moisture content of the propellant, the loading process can be completed outside the explosion-proof room.
[0049] 2. Transfer. Under the action of the second moving component, the rear end of the medicine box mounting plate abuts against the front end of the permeable plate, thus driving the medicine box and its base to move backward synchronously. Then, the third moving component works, pushing the medicine box and its base to move synchronously, so that the base is pressed by the clamping block. Then, the first moving component works, driving the medicine box and its base to move synchronously under the clamping component. Then, the clamping component works, clamping the medicine box. Then, the first moving component works again, driving the permeable plate and its base to move forward, so that the medicine box is moved above the permeable plate.
[0050] 3. Extraction. Activate the pressure plate cylinder to press the dewatering pad onto the charge box. Then, the vacuum pump located outside the explosion-proof enclosure operates to remove water. Once the moisture content of the charge reaches a certain level, the vacuum pump stops, completing the extraction process. The dewatering pad then returns to its original position. The pressure plate cylinder can also operate when the charge box is moved below the clamping assembly.
[0051] 4. Transfer. The first moving component operates, driving the permeable plate and the base of the medicine box to move backward, so that the medicine box is moved above the base of the medicine box. Then the clamping cylinder operates to release the medicine box, and then the first moving component, the second moving component, and the third moving component return to their original positions.
[0052] 5. Material Removal. Before personnel enter the explosion-proof room, the entire device is shut down. Then, the dewatered charge boxes and charge box bases are removed. At the same time, the charge boxes and charge box bases to be dewatered can be placed on the charge box mounting plate, waiting for the next dewatering cycle.
