[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 3 In the embodiment of the utility model, an improved structure for feeding a reactor comprises a barrel body 3, which is fixedly installed corresponding to the top feeding port 2 of the reactor 1, and a partition is fixedly connected inside the barrel body 3, which divides the barrel body 3 into a plurality of injection chambers 4, and an injection tube 5 is fixedly connected to the bottom surface of the barrel body 3 corresponding to each injection chamber 4, and a valve 6 is installed on the injection tube 5, and an air pump 8 is fixedly installed on the side wall of the barrel body 3, and an annular tube 9 is fixedly connected to the air inlet of the air pump 8 through a pipeline, and an air extraction branch pipe 10 is fixedly connected to the annular tube 9 corresponding to each injection chamber 4, and the air extraction branch pipe 10 is fixedly connected to the barrel body 3 and communicated with each injection chamber 4, and a feeding pipe 11 is also fixedly connected to each injection chamber 4 on the barrel body 3.

[0024] The injection chamber 4 is evacuated by the vacuum pump 8, so that negative pressure is formed in the injection chamber 4, so that the liquid raw material to be injected is sucked into the injection chamber 4 through the feed pipe 11, and negative pressure feeding is directly performed, without the need to manually lift the material for addition, making feeding more convenient.

[0025] A piston head 12 matching with the injection cavity 4 is slidably connected in the injection cavity 4, and a threaded handle 13 is rotatably connected to the top surface of the piston head 12. The threaded handle 13 threads through the top of the barrel body 3, and a threaded hole for threaded connection of the threaded handle 13 is opened on the top of the barrel body 3.

[0026] The position of the piston head 12 is adjusted by the threaded handle 13, so that the piston head 12 can shield and block the suction branch pipe 10 and the feed pipe 11, and control the annular pipe 9 to connect to the corresponding injection cavity 4 when the suction pump 8 is working, so as to facilitate targeted negative pressure feeding.

[0027] An exhaust pipe 14 is fixedly connected to the piston head 12 . The top of the exhaust pipe 14 slides through the top of the barrel body 3 and is threadedly connected to a sealing cap 15 . The top of the exhaust pipe 14 is provided with an external thread, and the inner wall of the sealing cap 15 is provided with an internal thread.

[0028] Scale marks 16 are evenly arranged on the exhaust pipe 14 .

[0029] By setting the exhaust pipe 14, the air below can be discharged when the piston head 12 is pushed downward by rotating the threaded handle 13, so as to facilitate the downward movement of the piston head 12.

[0030] The piston head 12 can be driven downward by rotating the threaded handle 13. When the upper valve 6 of the injection tube 5 is opened, the liquid raw material in the piston chamber 4 can be injected into the reactor. The feeding amount can be controlled by the cooperation of the scale line 16.

[0031] The bottom end of the injection tube 5 is fixedly connected with a connecting tube 7, and the connecting tube 7 is fixedly installed with the feeding port 2 by bolts and flanges, so that the overall improved structure is assembled with the reactor.

[0032] The air pump 8 is externally connected with a power supply and a switch.

[0033] The injection cavity 4 is slidably connected to the piston head 12, and the bottom is connected to the injection tube 5, so as to form a syringe structure. Through the surface tension of the liquid and the principle of air pressure, the force on the bottom layer of water molecules is the upward atmospheric pressure and the downward water pressure. The smaller the opening, the easier it is for the surface tension of the liquid to hold the water, making it more difficult for air to "invade" the water, so the water is not easy to come out.

[0034] The working principle of the utility model is:

[0035] When in use, the barrel body 3 is installed on the feeding port 2 of the reactor 1 through the connecting pipe 7. At this time, the blocking cover 15 can be opened, and the threaded handle 13 can be rotated so that the piston head 12 blocks the exhaust branch pipe 10 and the feed pipe 11, completing the initial preparation work.

[0036] When loading, the threaded handle 13 on the corresponding injection chamber 4 is rotated in the opposite direction to move the piston head 12 upward, so that the connection port of the feed pipe 11 and the exhaust branch pipe 10 is cleared, and the sealing cover 15 is further placed on the corresponding exhaust pipe 14. At this time, the exhaust pump 8 is started, and the exhaust branch pipe 10 is connected to the annular tube 9 for exhaust, so that a negative pressure is formed in the injection chamber 4, so that the added raw material is sucked into the injection chamber 4 through the feed pipe 11, and then the exhaust pump 8 is closed, and the sealing cover 15 is further opened, and the threaded handle 13 is rotated to make the piston head 12 move downward to the position of sealing the exhaust branch pipe 10 and the feed pipe 11, and then the sealing cover 15 is screwed on to re-seal the exhaust pipe 14, and the operation is repeated to load each injection chamber 4.

[0037] After the loading is completed, the valve 6 is opened to connect the injection tube 5 to the connecting tube 7 and the injection chamber 4. The force on the bottom layer of water molecules in the injection tube 5 is the upward atmospheric pressure and the downward water pressure. The smaller the opening, the easier it is for the surface tension of the liquid to hold the water, making it more difficult for the air to "invade" the water, thereby preventing the raw materials from leaking directly. When it is necessary to add materials, the threaded handle 13 is rotated to drive the piston head 12 downward, and the amount of movement is observed in conjunction with the scale line 16, so that the raw materials in the injection chamber 4 are squeezed into the connecting tube 7 through the injection tube 5, and further enter the reactor 1 through the feeding port 2, completing the feeding work of the reactor 1.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
