[0002] Solid caustic soda, or sodium hydroxide (chemical formula: NaOH) in solid form, is a highly corrosive strong alkali. It is typically a white, translucent crystal or lumpy substance, readily soluble in water, releasing a large amount of heat upon dissolution. It is also highly hygroscopic, absorbing moisture and deliquescing when exposed to air, and can absorb carbon dioxide and deteriorate. It is widely used in chemical, papermaking, textile, printing and dyeing, and soap manufacturing industries, as well as in metal cleaning and petroleum refining processes. In existing technologies, connecting the outlet to the pipeline is cumbersome due to the varying sizes of different pipes used for feeding solid caustic soda. Summary of the Invention

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a solid caustic soda feeding port adapted to a pipeline, comprising: a feeding hopper, a discharge port installed at the bottom of the feeding hopper, a flexible connecting tube installed at the bottom of the discharge port, a flexible connecting sleeve installed on the surface of the flexible connecting tube, a pipeline body embedded in the inner wall of the flexible connecting sleeve, and the inner wall of the pipeline body sleeved on the surface of the flexible connecting tube.
[0005] In a preferred embodiment, the surface of the flexible connecting sleeve is equipped with mounting blocks, and the number of mounting blocks is three sets, with fixing straps embedded in the inner wall of the mounting blocks.
[0006] In a preferred embodiment, the top of the feeding hopper is equipped with a top cover, the surface of the top cover has an inlet, and the top of the top cover is provided with a crushing component.

[0009] In a preferred embodiment, the inner wall of the feeding hopper is provided with equidistant limiting grooves, and the surface of the screen plate is provided with equidistant limiting blocks, the surfaces of which are mounted on the inner wall of the limiting grooves.
[0010] In a preferred embodiment, connecting blocks one are installed at equal intervals around the surface of the feeding hopper, and connecting blocks two are installed at equal intervals around the surface of the top cover.
[0011] In a preferred embodiment, the surface of the second connecting block is threaded with a bolt, and the surface thread of the bolt is embedded in the inner wall of the first connecting block.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. This utility model involves installing a flexible connecting sleeve at the bottom of the outlet onto the inner wall of the pipe body, while the surface of the pipe body is also mounted on the inner wall of the flexible connecting sleeve.

[0021] 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.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a solid caustic soda feeding port adapted to a pipeline, comprising: a feeding hopper 1, a discharge port 2 installed at the bottom of the feeding hopper 1, a flexible connecting tube 3 installed at the bottom of the discharge port 2, a flexible connecting sleeve 4 installed on the surface of the flexible connecting tube 3, a pipeline body 5 embedded in the inner wall of the flexible connecting sleeve 4, and the inner wall of the pipeline body 5 sleeved on the surface of the flexible connecting tube 3.
[0023] Specifically: When the device is first used, the flexible connecting sleeve 3 installed at the bottom of the outlet 2 is installed on the inner wall of the pipe body 5, so that the surface of the pipe body 5 is embedded in the inner wall of the flexible connecting sleeve 4, making the connection of the pipe more convenient and quick, adaptable to pipes of different sizes, and making the device more perfect.
[0024] In one embodiment, the surface of the flexible connecting sleeve 4 is equipped with mounting blocks 6, and there are three sets of mounting blocks 6. The inner wall of the mounting blocks 6 is embedded with fixing straps 7.
[0025] Specifically: After the pipeline installation is completed, the flexible connecting sleeve 4 is stably connected to the pipeline by tightening the fixing straps 7 embedded in the inner wall of the mounting block 6. There are three sets of mounting blocks 6 installed on the surface of the flexible connecting sleeve 4, which makes the connection and fixation effect better and prevents the connection from falling off. This makes it more convenient to connect the device to the pipeline and makes the device more perfect.
[0026] In one embodiment, a top cover 8 is installed on the top of the feeding hopper 1, and an inlet 801 is opened on the surface of the top cover 8. A crushing assembly 9 is provided on the top of the top cover 8. The crushing assembly 9 includes a motor 901. The surface of the motor 901 is installed on the top of the top cover 8. A rotating rod 902 is installed at the output end of the motor 901. A screen plate 10 is installed at the bottom of the rotating rod 902. Screen holes 11 are opened at equal intervals on the surface of the screen plate 10. A blocking shell 12 is installed on the top of the screen plate 10. A crushing roller 903 is installed on the bottom surface of the rotating rod 902.
[0027] Specifically: Solid caustic soda is fed into the device through the inlet 801 at the top of the top cover 8, and falls onto the sieve plate 10 installed at the bottom of the rotating rod 902. Small particles fall directly through the sieve holes 11 on the surface of the sieve plate 10, while large particles are crushed by the pulverizing roller 903 installed on the surface of the rotating rod 902 driven by the starting motor 901. The crushing roller 903 on the surface of the rotating rod 902 crushes the solid caustic soda falling on the top of the sieve plate 10, and then falls through the sieve holes 11 on the surface of the sieve plate 10. Finally, the caustic soda enters the pipeline through the outlet 2 installed at the bottom of the feeding hopper 1. This process crushes large solid caustic soda particles before they enter the pipeline, reducing blockages and making the device more efficient.
[0028] In one embodiment, the inner wall of the feeding hopper 1 is provided with a limiting groove 101 at equal intervals, and the surface of the screen plate 10 is provided with a limiting block 1001 at equal intervals. The surface of the limiting block 1001 is installed on the inner wall of the limiting groove 101.
[0029] Specifically: The limiting block 1001 installed on the surface of the screen plate 10 is installed on the inner wall of the limiting groove 101 opened in the inner wall of the feeding hopper 1, so that the screen plate 10 is more stable when installed inside the feeding hopper 1, the installation effect is better, and the device is more perfect.
[0030] In one embodiment, connecting blocks 102 are installed at equal intervals around the surface of the feeding hopper 1, and connecting blocks 802 are installed at equal intervals around the surface of the top cover 8. Bolts 13 are threadedly embedded on the surface of connecting blocks 802, and the threads of bolts 13 are embedded in the inner wall of connecting blocks 102.
[0031] Specifically: Align the connecting block 802 installed on the surface of the top cover 8 with the connecting block 102 installed on the surface of the feeding hopper 1, and then fix them with bolts 13 so that the top cover 8 can be better installed on the top of the feeding hopper 1. Remove the bolts 13 to release the fixation between the top cover 8 and the feeding hopper 1, so that the top cover 8 can be removed, making the device more complete.
[0032] Working principle: When the device is first used, the flexible connecting sleeve 3 installed at the bottom of the outlet 2 is installed on the inner wall of the pipe body 5, so that the surface of the pipe body 5 is embedded in the inner wall of the flexible connecting sleeve 4. Then, by tightening the fixing straps 7 embedded in the inner wall of the mounting block 6, the flexible connecting sleeve 4 is stably connected to the pipe. There are three sets of mounting blocks 6 installed on the surface of the flexible connecting sleeve 4, which makes the connection and fixation better and prevents the connection from falling off, thus making it easier to connect the device to the pipe and making the device more complete. Solid caustic soda is put into the device through the inlet 801 opened at the top of the top cover 8, so that the solid caustic soda falls onto the screen plate 10 installed at the bottom of the rotating rod 902. Small particles fall directly through the screen holes 11 opened on the surface of the screen plate 10, while large particles fall through the screen holes 11 opened on the surface of the screen plate 10. The caustic soda particles are crushed by the starting motor 901 driving the rotating rod 902, which in turn causes the crushing roller 903 mounted on the surface of the rotating rod 902 to roll. The crushed solid caustic soda falling on the top of the screen plate 10 is then crushed and falls through the screen holes 11 on the surface of the screen plate 10. The caustic soda then enters the pipeline through the discharge port 2 installed at the bottom of the feeding hopper 1. This process crushes large solid caustic soda particles before they enter the pipeline, reducing blockage. The connecting block 802 mounted on the surface of the top cover 8 is aligned with the connecting block 102 mounted on the surface of the feeding hopper 1 and then fixed with bolts 13. This allows the top cover 8 to be better installed on the top of the feeding hopper 1. Removing the bolts 13 releases the fixation between the top cover 8 and the feeding hopper 1, allowing the top cover 8 to be removed, thus improving the device.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
