[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] Example 1

[0025] Specifically, the feed guiding assembly 2 includes a vertical plate 21, a filter assembly 22, a feed guiding pipe 23, a telescopic pipe 24, a fixed plate 25, a water pump 26, and a feed pipe 27. The fixed plate 25 is fixed to one side surface of the concentration tower 1, the vertical plate 21 is fixed to the top surface of the fixed plate 25, the water pump 26 is installed at the bottom of the fixed plate 25, the feed pipe 27 is connected to the bottom of the water pump 26, the telescopic pipe 24 is installed at the input end of the water pump 26, the feed guiding pipe 23 is connected to the top of the telescopic pipe 24, and the filter assembly 22 is installed at the end of the feed guiding pipe 23 away from the telescopic pipe 24.
[0026] By adopting the above technical solution, when using the feed guide assembly 2 to introduce hydrochloric acid waste into the concentration tower 1, firstly, pull the feed guide pipe 23 to extend the telescopic pipe 24, thereby increasing the conveying distance of the feed guide pipe 23. At the same time, the direction of use of the feed guide pipe 23 can be changed by the telescopic pipe 24. Then, the feed guide pipe 23 is placed into the hydrochloric acid waste liquid to be introduced, and the water pump 26 is started. The water pump 26 introduces the hydrochloric acid waste liquid into the concentration tower 1 after filtering through the filter assembly 22. This reduces the participation of labor and avoids the situation of spillage when the operator pours out the hydrochloric acid waste liquid, which not only wastes hydrochloric acid resources but also causes unnecessary harm to the operator, thereby enhancing functionality.
[0027] Specifically, a connecting plate is installed on the surface of the upright plate 21 near the guide tube 23, and a storage rod is fixed to one side of the connecting plate.
[0028] By adopting the above technical solution, the guide tube 23 can be stored by the cooperation of the connecting rod and the storage rod, thus preventing the guide tube 23 from being damaged by being tilted at will.
[0029] Specifically, the filter assembly 22 includes a protective plate 221, a frame 222, a limiting ring 223, a threaded interface 224, and a filter cylinder 225. The guide tube 23 has a frame 222 at one end, a threaded interface 224 on one side of the frame 222, a filter cylinder 225 on the outer surface of the frame 222, a protective plate 221 fixed to one end of the filter cylinder 225, and a limiting ring 223 fixed to the side of the filter cylinder 225 away from the protective plate 221.
[0030] By adopting the above technical solution, when using the filter assembly 22, the filter cartridge 225 will filter the hydrochloric acid waste liquid entering the feed pipe 23, filtering out the solid substances and other impurities reacted in the hydrochloric acid waste liquid, preventing impurities from entering the concentration tower 1 and adhering to the inner wall of the concentration tower 1, thereby affecting the heating efficiency of the concentration tower 1. The protective plate 221 can protect the assembly and prevent damage from impacts that may affect the filtration effect. During assembly, it can be connected to one end of the feed pipe 23 through the threaded interface 224, thereby enhancing practicality and improving the filtration function of the equipment.
[0031] In this embodiment, when using the feed guide assembly 2 to introduce hydrochloric acid waste into the concentration tower 1, firstly, pull the feed guide pipe 23 to extend the telescopic pipe 24, thereby increasing the conveying distance of the feed guide pipe 23. Simultaneously, the direction of use of the feed guide pipe 23 can be changed through the telescopic pipe 24. Then, the feed guide pipe 23 is placed into the hydrochloric acid waste liquid to be introduced, and the water pump 26 is started. The water pump 26 then guides the hydrochloric acid waste liquid through the filter assembly 22 and into the concentration tower 1, thereby reducing labor involvement and preventing spillage caused by operators pouring hydrochloric acid waste liquid. This not only wastes hydrochloric acid resources but also causes unnecessary injury to operators, thus enhancing functionality. The connecting rod and the storage rod work together to store the feed tube 23, preventing it from being damaged by accidental tipping. When using the filter assembly 22, the filter cartridge 225 filters the hydrochloric acid waste liquid entering the feed tube 23, removing the solid substances and other impurities reacted in the waste liquid. This prevents impurities from entering the concentration tower 1 and adhering to its inner wall, thus affecting the heating efficiency of the concentration tower 1. The protective plate 221 protects the assembly from damage caused by impacts, thus preventing it from affecting the filtration effect. During assembly, it can be connected to one end of the feed tube 23 via the threaded interface 224, thereby enhancing its practicality and improving the filtration function of the equipment.

The top of the concentration tower 1 is provided with a collection pipe 32, and a sealing ring 31 is provided between the collection pipe 32 and the concentration tower 1. A collection cylinder 35 is provided on one side of the collection pipe 32, and an inclined block 36 is provided inside the collection cylinder 35. A discharge pipe 38 is provided on one side of the collection cylinder 35, and a plug 37 is provided inside the discharge pipe 38. A guide pipe 34 is connected between the collection cylinder 35 and the collection pipe 32, and a condenser pipe 33 is sleeved on the surface of the guide pipe 34.
[0034] By adopting the above technical solution, when using the hydrochloric acid collection component 3, after the hydrochloric acid waste liquid is heated by the concentration tower 1, the purified hydrochloric acid vapor will rise into the collection pipe 32 and then enter the guide pipe 34. The hydrochloric acid vapor in the guide pipe 34 is cooled by the condenser pipe 33, so that the hydrochloric acid vapor can flow into the collection cylinder 35 more quickly for easy collection. Then, the purified hydrochloric acid solution can be discharged by pulling out the plug 37. The inclined block 36 can reduce the residual hydrochloric acid solution in the collection cylinder 35, thereby avoiding the waste of hydrochloric acid resources and enhancing practicality.
[0035] Specifically, the outer surface of the collection tube 35 has an observation window, and a scale is provided on one side of the observation window.
[0036] By adopting the above technical solution, the observation window allows staff to easily observe the hydrochloric acid collection in the collection cylinder 35, thus facilitating the subsequent export of the hydrochloric acid solution.
[0037] In this embodiment, when using the hydrochloric acid collection assembly 3, after the hydrochloric acid waste liquid is heated by the concentration tower 1, the purified hydrochloric acid vapor rises into the collection pipe 32 and then enters the guide pipe 34. The hydrochloric acid vapor in the guide pipe 34 is cooled by the condenser pipe 33, so that the hydrochloric acid vapor can flow into the collection cylinder 35 more quickly for easy collection.

[0038] The structure and operating principle of the concentration tower 1 and the motor 4 in this utility model have been disclosed in a concentration tower for purifying and recovering waste hydrochloric acid disclosed in Chinese patent application number 202420217172.3.
[0039] The working principle and usage process of this utility model are as follows: This utility model adjusts a concentration tower for the purification and recovery of waste hydrochloric acid. When using the feed guiding component 2, to introduce waste hydrochloric acid into the concentration tower 1, first pull the feed guiding pipe 23 to extend the telescopic pipe 24, thereby increasing the conveying distance of the feed guiding pipe 23. Simultaneously, the direction of use of the feed guiding pipe 23 can be changed through the telescopic pipe 24. Then, the feed guiding pipe 23 is placed into the waste hydrochloric acid solution to be introduced, and the water pump 26 is started. The water pump 26 then guides the waste hydrochloric acid solution through the filter component 22 and into the concentration tower 1. This reduces labor input and avoids spillage when operators pour hydrochloric acid waste liquid, which not only wastes hydrochloric acid resources but also causes unnecessary harm to operators. It enhances functionality; the connecting rod and the storage rod work together to store the feed tube 23, preventing damage from accidental spillage. When using the filter assembly 22, the filter cartridge 225 filters the hydrochloric acid waste liquid entering the feed tube 23, removing reacted solids and other impurities to prevent contamination. The pollutant enters the concentration tower 1 and adheres to the inner wall of the concentration tower 1, thus affecting the heating efficiency of the concentration tower 1. The protective plate 221 can protect this component and prevent damage from impacts that may affect the filtration effect. During assembly, it can be connected to one end of the feed pipe 23 through the threaded interface 224, thereby enhancing practicality and improving the filtration function of the equipment. This utility model is an adjustment to a concentration tower for the purification and recovery of waste hydrochloric acid. When using the hydrochloric acid collection component 3, after the hydrochloric acid waste liquid is heated by the concentration tower 1, the purified hydrochloric acid vapor will rise. The hydrochloric acid vapor flows into the collection tube 32 and then into the guide tube 34. The condenser tube 33 cools the hydrochloric acid vapor in the guide tube 34, allowing it to flow into the collection cylinder 35 more quickly for easier collection. Then, the purified hydrochloric acid solution can be discharged by removing the plug 37. The inclined block 36 reduces the amount of residual hydrochloric acid solution in the collection cylinder 35, thus avoiding waste of hydrochloric acid resources and enhancing practicality. The observation window allows staff to easily observe the hydrochloric acid collection in the collection cylinder 35, facilitating the subsequent export of the hydrochloric acid solution.
