DETAILED DESCRIPTION
[0023] The utility model will be further explained in detail in combination with the drawings. The drawings are simplified schematic views, and only schematically illustrate the basic structure of the utility model, so that only the structures related to the utility model are shown.
[0024] Please refer to Figures 1-5 The technical scheme of the utility model is as follows: an ecological restoration water-retaining agent automatic polymerization reaction device, comprising a reaction kettle body 1, the top of the reaction kettle body 1 is provided with a pressure relief unit 2, and the pressure relief unit 2 comprises:
[0025] A pressure relief cylinder 22 is vertically arranged and communicates with the inside of the reaction kettle body 1 at the lower end, and a plurality of pressure relief holes 220 are arranged on the side wall in the axial direction.
[0026] A valve 23 is arranged in the pressure relief cylinder 22 and comprises a sealing surface that is in sealing cooperation with the inner side wall of the pressure relief cylinder 22.
[0027] A holding assembly 21 is arranged to limit the valve 23 in a holding state and release the valve 23 in a release state.
[0028] Specifically, the structure of the reaction kettle body 1 is consistent with the kettle body structure commonly used in the art, and the upper part is provided with a feeding port and a discharging port. The reaction kettle body 1 is further provided with other stirring devices (not shown in the figure) and constant temperature adjusting devices (not shown in the figure). The stirring devices and the constant temperature reaction devices are conventional structures on the reaction kettle body 1 in the art, and will not be described one by one. In the present application, the pressure relief unit 2 is arranged on the reaction kettle body 1. When the reaction kettle body 1 is normally powered, the valve piece 23 is located at the bottom of the pressure relief cylinder 22, and the sealing surface is in sealing cooperation with the inner side wall of the pressure relief cylinder 22, so as to close the pressure relief cylinder 22. At this time, the holding assembly 21 is in a holding state, and the valve piece 23 is limited. At this time, the valve piece 23 remains in the position of closing the pressure relief cylinder 22. When the power is suddenly cut off, the holding assembly 21 releases the valve piece 23, and the valve piece 23 can freely slide in the pressure relief cylinder 22. At this time, the high-pressure gas in the reaction kettle body 1 can push the valve piece 23 to move upward. After moving, the gas in the reaction kettle can be discharged from the pressure relief hole 220 on the side wall of the pressure relief cylinder 22, so as to achieve the effect of automatic pressure relief and reduce the risk of explosion of the reaction kettle body 1 due to excessive pressure.
[0029] Further, as a preferred embodiment, referring to Figure 3 、 Figure 7 , the upper end of the valve piece 23 is provided with a first limiting surface 242, and the first limiting surface 242 is in limiting cooperation with the upper end of the pressure relief cylinder 22. Specifically, the valve piece 23 includes a valve column 230 and a connecting rod 231, and the first limiting surface 242 is arranged at the end of the connecting rod 231. The sealing surface is the outer peripheral surface of the valve column 230. By arranging the first limiting surface 242, under the action of its own gravity, the valve piece 23 can slide downward in the pressure relief cylinder 22 in the normal state, so that the first limiting surface 242 abuts against the upper end of the pressure relief cylinder 22 for limiting cooperation. At this time, the valve piece 23 is in the state shown in Figure 3 . At this time, the valve column 230 is located at the lower end of the pressure relief cylinder 22, and the lower end of the pressure relief cylinder 22 is not provided with a pressure relief hole 220. Therefore, the valve column 230 can be in sealing cooperation with the inner side wall of the pressure relief cylinder 22.
[0030] Specifically, the valve column 230 is made of metal material and has a certain gravity, which can slide downward under its own gravity.
[0031] Further, as a preferred embodiment, the outer peripheral guide sleeve of the pressure relief cylinder 22 is provided with a protective shell 24, the upper end of the valve piece 23 is connected with the bottom of the protective shell 24, and the first limiting surface 242 is the bottom surface of the protective shell 24.
[0032] Specifically, referring to Figure 3 、 Figures 5-7, the protective shell 24 is made of thin-walled plastic or aluminum alloy material, has a bottom, the bottom is provided with a through hole 240, the upper end of the connecting rod 231 is provided with a threaded hole 2310, and the protective shell 24 and the connecting rod 231 can be locked by screwing the threaded rod 25 through the through hole 240 into the threaded hole 2310. Referring to Figure 3 , by setting the protective shell 24, when the first limiting surface 242 abuts against the end of the pressure relief cylinder 22, the protective shell 24 can shield the pressure relief hole 220 outside the pressure relief cylinder 22, which can reduce the probability of the pressure relief hole 220 being blocked by external dirt and improve safety.
[0033] Further, the lower end of the protective shell 24 is provided with a limiting piece 26, and the upper end of the pressure relief cylinder 22 is downwardly provided with a second limiting surface 223, and the limiting piece 26 is limitedly matched with the second limiting surface 223.
[0034] Further, the upper end of the pressure relief cylinder 22 is provided with a guide ring 221, and the outer circumferential surface of the pressure relief cylinder 22 is provided with the guide ring 221, which is guided and slidably matched with the inner side wall of the protective shell 24.
[0035] Specifically, referring to Figure 6 , Figure 7 , the upper end of the pressure relief cylinder 22 is provided with a guide ring 221, wherein the guide ring 221 is integrally arranged with the pressure relief cylinder 22, and the guide ring 221 is guided and slidably matched with the inner circumferential surface of the protective shell 24, wherein the lower end surface of the guide ring 221 is a second limiting surface 223, and the lower end of the protective shell 24 is detachably fixedly connected with a limiting piece 26 through the locking screw 25, and when the protective shell 24 slides in the vertical direction, the second limiting surface 223 can limit the limiting piece 26, and when the valve 23 moves upward under the action of the gas pressure during the pressure relief process, the second limiting surface 223 and the limiting piece 26 can be matched to avoid the valve 23 from being separated from the pressure relief cylinder 22, thereby improving safety.
[0036] Further, as a preferred embodiment, three guide grooves 222 are uniformly and circumferentially arranged on the guide ring 221, the guide grooves 222 are arranged in the axial direction, the depth of the guide grooves 222 is equal to the thickness of the guide ring 221, the inner circumferential surface of the protective shell 24 is correspondingly provided with three guide ribs 241, the guide ribs 241 are guided and slidably matched with the guide grooves 222, and when the protective shell 24 is sleeved outside the pressure relief cylinder 22, the guide ribs 241 can be in contact with and slidably guided with the outer circumferential surface of the pressure relief cylinder 22, and the pressure relief hole 220 is arranged in the area outside the guide ring 221. By this arrangement, the guiding smoothness of the protective shell 24 and the pressure relief cylinder 22 can be ensured, and the protective shell 24 will not be attached to the end of the pressure relief hole 220, thereby ensuring that the pressure relief unit 2 can work normally.
[0037] Further, as a specific embodiment, the specific structure of the retaining assembly 21 is as follows: referring to Figure 3, Figure 4 The holding assembly 21 includes a support member 210 disposed at the upper end of the reactor body 1, a friction plate 211 horizontally guided on the support member 210, a permanent magnet 216 disposed on the friction plate 211, and an electromagnet 215 disposed on the support member 210.
[0038] Specifically, when the reactor body 1 is powered on and operating normally, the state of the pressure relief unit 2 is as follows: Figure 3 As shown, when the electromagnet 215 is energized, it generates magnetism. This magnetism repels the permanent magnet 216, pushing the friction plate 211 into contact with the outer wall of the protective shell 24. The friction plate 211 and the outer wall of the protective shell 24 engage in frictional contact, maintaining the position of the protective shell 24 through friction, thereby achieving the effect of maintaining the position of the valve 23. When the power is suddenly cut off, the electromagnet 215 demagnetizes, and the pressure between the friction plate 211 and the outer wall of the protective shell 24 disappears. At this time, the protective shell 24 can slide vertically, and is in a released state.
[0039] Specifically, by providing guide ribs 241 inside the protective shell 24, the guide ribs 241 can abut against the outer wall of the pressure relief cylinder 22. When the friction plate 211 is pressed against the protective shell 24, the guide ribs 241 can abut against the side wall of the pressure relief cylinder 22 to provide support, ensuring that the friction plate 211 and the outer wall of the protective shell 24 are in full contact and that there is sufficient friction between them.
[0040] Further, preferred, reference Figure 4 The support member 210 has a channel 214, and the permanent magnet 216 and electromagnet 215 are correspondingly arranged in the channel 214. By setting the channel 214, a transmission channel 214 is provided for the magnetic field.
[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
