Description

Technical Field

[0001] This utility model relates to the field of reaction tank structure technology, specifically to a reaction liquid tank for defluorination in phosphorus chemical industry. Background Technology

[0002] Defluorination is a common process in modern phosphate chemical production. Its function is to remove fluorine from raw materials, ensuring product quality, and it is a crucial step in the process. The production process typically involves mixing and reacting the raw materials in a reaction tank. A certain amount of defluorinating agent is added to the tank, causing a reaction that achieves defluorination.

[0003] The reaction tanks currently in use are traditional square stirred tanks. The solid substances produced during the reaction process tend to crystallize at the bottom or on the inner wall of the tank, which directly affects the tank volume and causes corrosion of the stirring blades. Moreover, cleaning the reaction tank requires a lot of manpower and resources, and shutdown for cleaning takes a long time. Therefore, a reaction tank for defluorination in phosphate chemical industry is proposed. Utility Model Content

[0004] The technical solution adopted by this utility model to solve the technical problem is:

[0005] A reaction tank for defluorination in phosphate chemical industry includes a stirring tank. A rotating shaft is rotatably connected to the middle of the bottom side wall of the stirring tank. Stirring arms are uniformly fixedly connected to both sides of the rotating shaft. A scraper is connected to one end of each stirring arm. Bottom columns are rotatably connected to both sides of the rotating shaft near the bottom. A deflector plate is fixedly connected to both sides of each bottom column. The end of the deflector plate away from the bottom column is in contact with the bottom of the stirring tank.

[0006] As a preferred embodiment of this utility model, a rotating groove is provided on the inner wall of the mixing tank opposite to the bottom column, and a surrounding plate is rotatably connected to the opening of the rotating groove opposite to the bottom column, and one end of the bottom column is rotatably inserted into the rotating groove.

[0007] As a preferred embodiment of this utility model, a bevel gear is fixedly connected to one end of the bottom column located in the rotating groove, and a toothed ring is fixedly connected to the lower side wall of the rotating groove, with the bevel gear meshing with the toothed ring.

[0008] As a preferred embodiment of this utility model, the stirring arms are staggered, the scraper is rotatably connected to the end of the stirring arm away from the rotating axis, the scraper has a triangular structure, and the sharp end is in contact with the inner wall of the stirring tank.

[0009] As a preferred embodiment of this utility model, the top of the mixing tank is detachably connected to a top cover, the top side wall of the top cover is detachably connected to a motor, and the output end of the motor passes through the top cover and is detachably connected to the top of the rotating shaft.

[0010] As a preferred embodiment of this utility model, the two outer side walls of the mixing tank that are far apart from each other are detachably connected to a support plate, and the top side wall of the support plate is detachably connected to a vibration motor, with one end of the vibration motor fitting against the outer wall of the mixing tank.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] Because a scraper is rotatably connected to one end of the mixing arm, when the mixing arm rotates with the rotating shaft, it can drive the scraper to rotate synchronously along the inner wall of the mixing tank. As the scraper rotates, its sharp end will scrape off the scale adhering to the inner wall of the mixing tank. And because the mixing arms are staggered, each scraper has an independent cleaning area, avoiding repeated scraping and damage to the inner wall of the mixing tank.

[0013] In addition, since two bottom columns are rotatably connected at the bottom of the rotating shaft, and the bottom columns are connected to the gear ring through bevel gears, when the bottom columns are driven to rotate, the interaction between the bevel gears and the gear ring will drive the actuating plate to rotate, thereby cleaning the structure at the bottom of the mixing tank.

[0018] 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.

[0019] Please refer to the following: Figure 1-3 , Figure 1This is a three-dimensional structural schematic diagram of a preferred embodiment of the present invention; Figure 2 This is a cross-sectional structural diagram of a preferred embodiment of the present invention; Figure 3 This is a preferred embodiment of the present utility model. Figure 2 Enlarged structural diagram at point A in the middle.

[0020] This utility model provides a reaction tank for defluorination in phosphate chemical industry, including a stirring tank 1. A rotating shaft 6 is rotatably connected to the middle of the bottom side wall of the stirring tank 1. Stirring arms 7 are evenly fixedly connected to both sides of the rotating shaft 6. A scraper 8 is connected to one end of the stirring arm 7. Bottom columns 9 are rotatably connected to both sides of the rotating shaft 6 near the bottom. A deflector plate 10 is fixedly connected to both sides of each bottom column 9. The end of the deflector plate 10 away from the bottom column 9 is in contact with the bottom of the stirring tank 1. The stirring arms 7 are staggered. The scraper 8 is rotatably connected to the end of the stirring arm 7 away from the rotating shaft 6. The scraper 8 has a triangular structure and its sharp end is in contact with the inner wall of the stirring tank 1.

[0021] A rotating groove 11 is provided on the inner wall of the mixing tank 1 opposite to the bottom column 9. A surrounding plate 12 is rotatably connected to the opening of the rotating groove 11 opposite to the bottom column 9. One end of the bottom column 9 is rotatably inserted into the rotating groove 11. A bevel gear 13 is fixedly connected to the end of the bottom column 9 located in the rotating groove 11. A gear ring 14 is fixedly connected to the side wall of the rotating groove 11 below the bevel gear 13. The bevel gear 13 and the gear ring 14 are meshed together.

[0022] The top of the mixing tank 1 is detachably connected to a top cover 2. The top side wall of the top cover 2 is detachably connected to a motor 3. The output end of the motor 3 passes through the top cover 2 and is detachably connected to the top of the rotating shaft 6.

[0023] The technical advantages of this solution are:

[0024] The motor 3 drives the rotating shaft 6 to rotate, which in turn drives the stirring arm 7 to rotate synchronously. As the stirring arm 7 rotates, it carries the scraper 8 to rotate on the inner wall of the mixing tank 1. The force generated by the rotation acts on the scraper 8, and the sharp end of the scraper 8 can clean the scale adhering to the inner wall of the mixing tank 1, ensuring the cleanliness of the inner wall of the mixing tank 1. At the same time, because the stirring arm 7 has a staggered structure, it can ensure that the cleaning area of ​​the scraper 8 is relatively independent, avoiding repeated cleaning of the same area and causing wear to the inner wall of the mixing tank 1. In addition, in order to ensure the cleaning effect, the cleaning area of ​​each scraper 8 can overlap to a certain extent, so as to avoid the area between two scrapers 8 being uncleaned.

[0025] Furthermore, as the rotating shaft 6 rotates, it drives the bottom column 9 to rotate. Through the meshing connection of the bevel gear 13 and the gear ring 14, the bottom column 9 can be driven to rotate. The rotation of the bottom column 9 drives the actuating plate 10 to rotate along the bottom column 9. Since the actuating plate 10 only contacts the bottom of the mixing tank 1 when it is in a vertical position, it can avoid motion interference and clean the bottom side wall of the mixing tank 1. Through the cooperation of the scraper 8 and the actuating plate 10, the inner wall of the mixing tank 1 can be thoroughly cleaned.

[0026] In addition, the two side walls of the mixing tank 1 that are far apart from each other are detachably connected to a support plate 4, and the top side wall of the support plate 4 is detachably connected to a vibration motor 5, with one end of the vibration motor 5 attached to the outer wall of the mixing tank 1.

[0027] The technical effects of this solution are as follows: starting the vibration motor 5 can vibrate the side wall of the mixing tank 1, and the vibration can shake off the structure adhering to the inner wall of the mixing tank 1, thus cleaning the small structure. The vibration motor 5, together with the scraper 8 and the agitator 10, can fully guarantee the cleaning effect and efficiency of the structure, reduce the time wasted due to cleaning, and improve the cleaning efficiency.

[0028] Specifically, when using this utility model, the material to be processed is placed into the mixing tank 1, and the motor 3 is started to drive the rotating shaft 6 to rotate, thereby driving the mixing support arm 7 and the bottom column 9 to rotate. At the same time, the bottom column 9 will achieve the effect of self-rotation under the cooperation of the bevel gear 13 and the gear ring 14, thereby driving the actuating plate 10 to rotate along the bottom column 9. As it rotates, the material can be stirred. At the same time, the scraper 8 and the actuating plate 10 can clean the material adhering to the inner wall of the mixing tank 1 during the stirring process to avoid scaling. The set enclosure plate 12 can prevent the material from entering the rotating groove 11 and affecting the connection stability of the bevel gear 13 and the gear ring 14.

[0029] When simple cleaning is required, simply drive the rotating shaft 6 to rotate as described above. You can choose whether to activate the vibration motor 5 as needed. The cooperation of these three components can efficiently clean the scale and ensure the defluorination efficiency of the mixing tank 1.

[0030] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0031] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
