[0002] Furan ammonium salts are mainly used in the refining of cefuroxime raw materials or preparations. The raw materials for the production of furan ammonium salts mainly include acetyfuran, sodium nitrite, and methoxyammonium salts. The specific preparation process is as follows: 1. Reaction of acetyfuran and sodium nitrite: Under the catalysis of metal salts, acetyfuran and sodium nitrite react to produce furanone acid. 2. Mixed reaction of furanone acid and methoxyammonium salt: Furanone acid and methoxyammonium salt are mixed and reacted to obtain furan ammonium salts. Through the above steps, furan ammonium salts can be prepared efficiently. This method is simple to operate, low in cost, safe, and has a high yield, and the quality of the obtained product meets national standards.

[0003] When adding raw materials for the preparation of furan ammonium salt through the feed pipe at the top of the reactor, some raw materials adhere to the inner wall of the feed pipe. To address this, patent CN217910353U discloses a furan ammonium salt raw material mixing device, which uses a cleaning hood to clean and seal the inner wall of the feed pipe. However, this device requires disassembly and reassembly from the reactor each time it is used. After disassembly, storage and other operations can easily cause contamination of the cleaning hood, and it is not convenient to use. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 As shown, a cleaning device for the raw material feed pipe 101 of a furan ammonium salt reactor 1 is provided. The upper end of the feed pipe 101 is equipped with a flange 102, such as... Figure 2 , Figure 3 As shown, the cleaning device includes a support rod 2 connected to the reactor 1. A rotating plate 3 is rotatably connected to the upper end of the support rod 2. A slidable push rod 402 passes through the end of the rotating plate 3 away from the support rod 2. A handle 404 is provided at the upper end of the push rod 402. A cleaning plug 5 that cooperates with the feed pipe 101 is provided at the lower end of the push rod 402. The lower edge of the cleaning plug 5 is chamfered. The cleaning plug 5 is rotated to the top of the feed pipe 101 and extended into the feed pipe 101. The cleaning plug 5 cooperates with the inner wall of the feed pipe 101. By pushing the cleaning plug 5 with the push rod 402, the raw materials adhering to the inner wall of the feed pipe 101 can be pushed into the reactor 1.

[0024] After cleaning, the cleaning plug 5 can be pulled out of the feed pipe 101. Rotate the rotating plate 3 to move the cleaning plug 5 away from the top of the feed pipe 101. The feed pipe 101 can then be closed with the cover plate.

[0025] To increase ease of use, a sealing cover 4 is fitted on the outside of the push rod 402. The sealing cover 4 is located between the cleaning plug 5 and the rotating plate 3. The sealing cover 4 and the push rod 402 are in sliding fit. A spring 6 is connected between the rotating plate 3 and the sealing cover 4. During cleaning, the sealing cover 4 covers the upper end of the feed pipe 101. Under the action of the spring 6, the sealing cover 4 is pressed against the upper end of the flange 102.

[0026] The lower end of the sealing cover 4 is provided with a positioning post 401, which mates with the bolt holes on the flange 102.

[0027] To enhance sealing, a sealing ring 405 is provided at the lower end of the sealing cover 4.

[0028] The upper end of the cleaning plug 5 is provided with a magnet 501 that attracts the sealing cover 4. After cleaning, the cleaning plug 5 can be fixed to the lower end of the sealing cover 4. At the same time, the cleaning plug 5 is located inside the feed pipe 101 to achieve the sealing of the feed pipe 101.

[0029] The lower end of the handle 404 is provided with a limiting sleeve 403. Push the push rod 402 downward. When the limiting sleeve 403 contacts the rotating plate 3, the push rod 402 moves downward to the lowest point. The bottom of the cleaning plug 5 extends out from the bottom of the feed pipe 101, and the upper end of the cleaning plug 5 is located inside the feed pipe 101.

[0030] After the raw materials are added, pull the push rod 402 upward by using the handle 404. After the cleaning plug 5 touches the sealing cover 4, continue to pull the push rod 402 upward, which will cause the sealing cover 4 to compress the spring 6, pulling up the sealing cover 4. Rotate the rotating plate 3 so that the sealing cover 4 is located at the upper end of the feed pipe 101. Slowly move the handle 404 downward to extend the cleaning plug 5 into the feed pipe 101. At the same time, under the action of the spring 6, the sealing cover 4 covers the upper end of the flange 102. The positioning pin 401 engages with the bolt hole of the flange 102. Push the handle 404 downward, and the cleaning plug 5 is pushed from the upper end to the lower end of the feed pipe 101 to complete the cleaning. Then pull the handle 404 upward to make the cleaning plug 5 adhere to the bottom of the sealing cover 4, thereby sealing the feed pipe 101. When it is necessary to add material again, pull the sealing cover 4 upwards using handle 404 to separate the sealing cover 4 from the flange 102. Rotate the rotating plate 3 to move the cleaning plug 5 away from the feed pipe 101. At the same time, the cleaning plug 5 will not fall under the action of the magnet 501, preventing the cleaning plug 5 from contacting the reactor 1.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
