Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical production equipment technology, specifically to a synthesis production system for p-toluenesulfonamide sodium chloride. Background Technology
[0002] p-Toluenesulfonamide sodium chloride (chloramine T) is a white crystalline powder with a slight chlorine odor. It is not bitter and slowly decomposes when exposed to air, with only a 0.1% decrease in available chlorine per year. It gradually loses chlorine and turns yellow. As a disinfectant, this product is a broad-spectrum disinfectant for external use, containing 24-25% available chlorine. It is relatively stable and has a killing effect on bacteria, viruses, fungi, and spores.
[0003] A search revealed a production system for p-toluenesulfonamide sodium chloride salt in Chinese patent application number 201520989351.X. This system mainly includes a dissolving kettle, a first filter, a salt-forming reactor, a second filter, and a centrifugal dehydrator. The inlet of the dissolving kettle is connected to a liquid alkali storage tank and a p-toluenesulfonamide storage tank. The outlet of the dissolving kettle is connected to the inlet of the first filter. The liquid phase outlet of the first filter is connected to the inlet of the salt-forming reactor. The salt-forming reactor also has a sodium hypochlorite storage tank. The outlet of the salt-forming reactor is connected to the inlet of the second filter. The solid phase outlet of the second filter is connected to the inlet of the centrifugal dehydrator. The centrifugal dehydrator has a wastewater outlet and a product outlet. This p-toluenesulfonamide sodium chloride salt production system offers advantages such as low production cost, high production efficiency, high product purity, and minimal environmental pollution.
[0004] In the above technical solution, after the raw materials are dissolved, they are filtered by a filter to remove solid impurities. However, the solid impurities trapped in the filter will still leave raw materials, resulting in raw material loss and low production efficiency. Utility Model Content

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.
[0024] Example
[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in one embodiment of this utility model, a synthesis production system for p-toluenesulfonamide sodium chloride includes a tank 1, a filter hood 2, and a flushing pipe 3. The filter hood 2 is installed in the cavity inside the tank 1. An inner cylinder 201 is integrally formed in the middle of the filter hood 2. The inner cylinder 201 has uniformly distributed filter holes 202. The filter hood 2 filters the material entering the tank 1, thereby separating solid impurities from the material. The liquid material flows through the filter holes 202 on the inner cylinder 201 into the tank 1, and is then discharged from the outlet pipe 101 and transported to the next process equipment for subsequent preparation operations. The tank body 1 has a top cover 102 with a feed pipe 103, which facilitates the injection of the reacted raw materials from the dissolving kettle into the tank body 1 for processing. The bottom of the tank body 1 is equipped with a liquid outlet pipe 101 to ensure the smooth discharge of the processed raw materials. The top cover 102 is equipped with a rinsing pipe 3, and the branch pipes 301 connected to the rinsing pipe 3 extend into the internal cavity of the filter cover 2. The branch pipes 301 are provided with water outlet holes 304. Water is evenly distributed to each branch pipe 301 through the rinsing pipe 3 and discharged to rinse the impurities trapped in the filter cover 2, separate the raw materials remaining in the impurities, reduce the loss of raw materials, and improve production efficiency.
[0026] like Figure 2 and Figure 3As shown, in some embodiments, a return pipe 107 is connected to the liquid outlet pipe 101 at the bottom of the tank 1, which facilitates the smooth discharge of the rinsing liquid in the tank 1. With the valve on the return pipe 107 and the external pipe, the rinsing liquid is injected back into the dissolving kettle, improving the utilization rate of raw materials. The ends of the liquid outlet pipe 101 and the return pipe 107 are equipped with quick-connect plugs, which facilitates the quick connection of external pipes and improves the convenience of use. The feed pipe 103 is installed through the top cover 102. The end of the feed pipe 103 is integrally provided with a connecting end plate, which facilitates a stable connection with the outlet of the dissolving kettle, thereby injecting the product after reaction in the dissolving kettle into the tank 1 for filtration. In addition, an anti-clogging cone 104 is installed in the feed pipe 103 to prevent the feed pipe 103 from being blocked during the feeding process and ensure smooth use.
[0027] The anti-clogging cone 104 is fixedly connected to the feed pipe 103 by the connecting rod 105, which facilitates the stable installation of the anti-clogging cone 104 in the feed pipe 103 and ensures stable use. The lower end of the anti-clogging cone 104 extends to the outside of the feed pipe 103 and is fixedly connected to the diversion hood 106, which facilitates the stable installation of the diversion hood 106 directly below the feed pipe 103. The diversion hood 106 abuts against the upper part of the inner cylinder 201, and the lower edge of the diversion hood 106 extends to the periphery of the inner cylinder 201. The diversion hood 106 is used to divert the material injected into the tank 1 from the feed pipe 103, so that it can be evenly distributed in the filter cover 2, thereby improving the subsequent filtration efficiency.
[0028] like Figure 2 and Figure 4 As shown, in some embodiments, the upper port of the filter cover 2 is fixedly connected with a lifting lug 203, which facilitates the lifting of the entire filter cover 2 during the assembly and disassembly process, so that the filter cover 2 can be smoothly placed into the tank 1 or removed from the tank 1, thereby cleaning the impurities in the filter cover 2 and improving the convenience of use.
[0029] like Figure 2 and Figure 5 As shown, in some embodiments, the flushing pipe 3 is fixedly connected to the top cover 102 by a connecting buckle 303, which facilitates the stable installation of the flushing pipe 3 on the top cover 102 and ensures stable use. The water inlet pipe 302 connected to the flushing pipe 3 passes through the top cover 102 and extends to the outside of the tank 1. The end of the water inlet pipe 302 is equipped with a quick-connect connector, which facilitates the quick connection of the external flushing water supply pipe to the water inlet pipe 302, so that the two are stably connected together, thereby inputting flushing water into the flushing pipe 3 to flush the impurities accumulated in the filter cover 2, and then flushing down the raw materials remaining in the impurities, improving the utilization rate of raw materials and reducing losses. The branch pipes 301 are distributed in a ring array on the flushing pipe 3, and the branch pipes 301 are provided with evenly distributed water outlet holes 304 to facilitate the discharge of water, thereby completing the flushing of impurities.
[0030] In use, the tank body 1 and all external auxiliary pipes are stably connected. Then, the raw materials reacted in the dissolving vessel are injected into the tank body 1. The filter hood 2 inside the tank body 1 filters the raw materials, trapping solid impurities. The liquid is discharged from the outlet pipe 101 and input into the next process equipment for further processing. Then, the rinsing water is injected from the inlet pipe 302 into the rinsing pipe 3 and distributed to each branch pipe 301. The water is discharged from the outlet hole 304 on the branch pipe 301 to rinse the solid impurities trapped in the filter hood 2. The rinsed water is discharged from the return pipe 107 on the outlet pipe 101 and injected into the dissolving vessel through the connected conveying pipe, so that the raw materials remaining in the solid impurities can be reused.
[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
