Before the pouring process, since the end of the four-way tube 4 above the left outer wall of the inner cylinder 1 is welded with a nozzle 41, the nozzle 41 is connected to an external air pump. The manual air-blocking valve 42 is closed first to prevent air leakage, and then air is pumped out through the nozzle 41 on the four-way tube 4 connected to the external air pump to pump air into the inside of the inner cylinder 1 into a negative pressure. The internal pressure value of the inner cylinder 1 can be read through the pressure gauge 43 threadedly connected to the four-way tube 4. When the value of the pressure gauge 43 reaches the minimum value, the air is pumped for 10 minutes.
[0021] See also Figure 1-Figure 3, a water bath heating assembly 2 is installed on the outside of the inner cylinder 1, and the water bath heating assembly 2 includes an outer cylinder 21 and a first upper joint 22 and a first lower joint 23 respectively arranged on the upper and lower sides of the surface of the outer cylinder 21, the outer cylinder 21 is fixed to the outside of the inner cylinder 1, the lower end of the outer cylinder 21 is fixed to the upper end of the base 5, and a closed space is provided between the funnel tube 3 and the feeding assembly 31, and the feeding assembly 31 includes a funnel 32, a feeding tray 33, a rotating rod 34, a fixed tray 35, a distributing tray 36 and a connecting tube 37, the funnel 32 is fixed to the inner wall of the funnel tube 3, and the closed space is provided between the outer wall of the funnel 32 and the inner wall of the funnel tube 3, the fixed tray 35 is fixed to the inner bottom of the funnel 32, and the lower part of the fixed tray 35 is connected to the funnel The lower end of the cylinder 3 is fixed through, and the feed disc 33 is movably arranged at the bottom of the funnel 32. The feed disc 33 is movably arranged at the upper end of the fixed disc 35. The rotating rod 34 is fixed to the center of the upper end of the feed disc 33. The connecting cylinder 37 is fixed to the lower end of the funnel cylinder 3, and the distributing disc 36 is fixed to the lower end of the connecting cylinder 37. The upper ends of the feed disc 33, the fixed disc 35 and the distributing disc 36 are all provided with feeding holes distributed in an annular manner. The upper and lower sides of the surface of the funnel cylinder 3 are respectively provided with a second upper joint 38 and a second lower joint 39. The second upper joint 38 and the second lower joint 39 are both communicated with the confined space. A confined space is provided inside the funnel cylinder 3, and the second upper joint 38 and the second lower joint 39 welded on the left side of the funnel cylinder 3 are used to connect the external The leather tube is inserted into the second upper joint 38 and the second lower joint 39, so that the external heated water flows into the closed space of the funnel tube 3 through the second lower joint 39, and then flows out of the closed space of the funnel tube 3 through the second upper joint 38, forming a heated water circulation. In this way, when pouring medicine, the medicine is poured in from the top of the funnel tube 3, and the rotating rod 34 is rotated, and the rotating rod 34 drives the feed plate 33 to rotate. As the feed plate 33 and the feed hole of the fixed plate 35 are misaligned, the medicine leakage speed is controlled, and the medicine is kept warm by the heated water circulation in the closed space of the funnel tube 3, so that the medicine can leak downward from the funnel tube 3 smoothly, and the hot water flows in from the first lower joint 23 on the outer wall of the outer cylinder 21, and flows out from the first upper joint 22 above the outer wall of the outer cylinder 21. Circulating hot water is formed, so that the medicine flowing from the funnel tube 3 into the solid rocket engine casing maintains good fluidity. In this way, a constant high temperature (high temperature here specifically refers to higher than room temperature) inside the device can be ensured by circulating heated water. By controlling the temperature of the heated water, the temperature inside the device can be controlled, so that medicine with poor fluidity can maintain good fluidity at a constant high temperature. Different heating water temperatures are set for medicines with different high temperature requirements, so that the pouring process can proceed smoothly, which greatly increases the convenience of pouring medicine for solid rocket engines and the diversity of pouring medicine types. At the same time, air is continuously pumped out through the nozzle 41 on the four-way pipe 4, so that the air in the medicine is reduced, thereby reducing the number of bubbles in the medicine, and greatly improving the pouring quality.
[0022] See also Figure 3-Figure 4 , the upper end of the base 5 is provided with a pouring rack 6 located in the inner cylinder 1, the pouring rack 6 includes a bottom plate 61, columns 62 fixed at the four corners of the upper end of the bottom plate 61, a fixing ring 63 fixed between the columns 62 and a limit plate 64 plugged into the upper end of the fixing ring 63, the upper end of the base 5 is provided with a groove 51, the bottom plate 61 is plugged into the groove 51, before the pouring process, the built-in pouring rack 6 is taken out, and the limit plate 64 on the pouring rack 6 is replaced according to the outer diameter of the solid rocket engine shell to be poured, and the limit plate 64 of the corresponding size is placed in the fixing ring 63, and then the solid rocket engine shell is vertically placed in the hole in the center of the limit plate 64, so that the solid rocket engine shell is fixed, and then the pouring rack 6 together with the solid rocket engine shell is placed in the inner cylinder 1. In this way, by replacing the limit plates 64 of different sizes, the built-in pouring rack 6 can be adapted to solid rocket engine shells of different outer diameters, which greatly increases the flexibility of the solid rocket engine water bath heating pouring device.
[0023] See also Figure 1 , the inner cylinder body 1 is equipped with a window cylinder 11 at both the front and rear ends, and a sight glass 12 is installed inside the window cylinder 11. By setting the window cylinder 11 and the sight glass 12, the pouring situation in the inner cylinder body 1 can be observed.
[0024] Working principle: First, before pouring the medicine, take out the medicine pouring rack 6 built into the device, and the funnel tube 3 needs to be removed before taking it out. The funnel tube 3 and the inner cylinder 1 are detachable (the funnel tube 3 is placed in the limiting circle on the upper surface of the inner cylinder 1, and the sealing ring is pressed and sealed by the dead weight of the funnel tube 3. The upper surface of the inner cylinder 1 is provided with a sealing groove, and the sealing ring is placed in the sealing groove). After removing the funnel tube 3, the medicine pouring rack 6 can be taken out upwards, and then the limiting plate 64 on the medicine pouring rack 6 is replaced according to the outer diameter of the solid rocket engine shell for which medicine pouring is required, and the limiting plate 64 of the corresponding size is placed in the fixing ring 63, and then the solid rocket engine shell is vertically placed in the hole in the center of the limiting plate 64 to fix the solid rocket engine shell. Then put the medicine pouring rack 6 together with the solid rocket engine shell into the inner cylinder 1, so that the bottom plate 61 of the medicine pouring rack 6 will be inserted into the groove 51 to position the medicine pouring rack 6, and then reinstall the upper funnel 3, and use four leather hoses to connect the first upper joint 22, the first lower joint 23, the second upper joint 38 and the second lower joint 39. The other ends of the four leather hoses are connected to an external heating water circulation device (not within the scope of this application, a conventional purchased part), turn on the external heating water circulation device, heat the water therein to a predetermined temperature, and connect the external heating water circulation device to the solid rocket engine water bath heating medicine pouring device through a leather hose to form a water circulation path. The funnel tube 3 of this device is provided with a closed space for heating Water circulation, and a closed space is also provided between the inner wall of the outer cylinder 21 of the device and the outer wall of the inner cylinder 1 for heating water circulation. The heated water is continuously heated by the external heating water circulation device and then introduced into the closed space inside the outer cylinder 21 and the inner cylinder 1 of the device. Then the nozzle 41 is connected to the external air pump, and the manual air-blocking valve 42 is closed first to prevent air leakage. Then, air is pumped outwards through the nozzle 41 connected to the external air pump on the four-way pipe 4 to pump the inside of the inner cylinder 1 into a negative pressure. The internal pressure value of the inner cylinder 1 can be read through the pressure gauge 43 threadedly connected to the four-way pipe 4. When the value of the pressure gauge 43 reaches the minimum value, the air is pumped for 10 minutes. In this way, when pouring the medicine, the medicine is poured in from the top of the funnel tube 3. By rotating the rotating rod 34, the rotating rod 34 drives the feed plate 33 to rotate. As the feed hole of the feed plate 33 and the fixed plate 35 are misaligned, the leakage speed of the medicine is controlled, and the heated water circulation in the closed space of the funnel tube 3 is used to keep the medicine warm, so that the medicine can smoothly leak downward from the funnel tube 3, and the hot water flows in from the first lower joint 23 on the outer wall of the outer cylinder body 21, and flows out from the first upper joint 22 above the outer wall of the outer cylinder body 21, forming circulating hot water, so that the medicine flowing from the funnel tube 3 into the solid rocket engine casing maintains good fluidity, and at the same time, air is continuously sucked out through the nozzle 41 on the four-way pipe 4, so that the air in the medicine is reduced, thereby reducing the number of bubbles in the medicine, and greatly improving the pouring quality.
