Description

Technical Field

[0001] This utility model relates to the field of crystallizer technology, and more specifically to an acidification crystallization precipitation instrument. Background Technology

[0002] Acidification crystallization is a separation and purification technique that reduces the solubility of a target substance by adjusting the pH of the solution, causing it to precipitate as crystals. It is widely used in chemical synthesis, chemical production, and laboratory preparation. For example, a crystallizer is a key piece of equipment in the crystallization process, providing a suitable environment to allow the solute in the solution to reach a supersaturated state, thus precipitating crystals. For instance, the acidification reaction crystallizer for producing boric acid has internal structures such as an upper guide tube, a lower guide tube, blades, and a guide cone, allowing the reaction and crystallization to occur simultaneously, improving production efficiency.

[0003] For example, an acidification crystallization precipitation device with prior art disclosure number CN219721965U uses a stirrer to ensure uniform mixing of sulfuric acid and the feed solution, thereby regulating the acidification rate and preventing the aggregation of sebacic acid after precipitation, thus creating conditions for washing. Furthermore, this device is easy to operate, and its volume can be designed according to production needs, effectively reducing costs.

[0004] However, the existing technology described above still has the following problems in use: since the stirring paddle can only stir the acidified crystallization material in a specified direction, the stirring effect is low, and some material will remain on the wall, which will not only affect the stirring effect, but also affect the subsequent precipitation. Based on this, the present invention provides an acidified crystallization precipitation instrument with better stirring effect. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides an acidification crystallization precipitation instrument. The acidification crystallization material is thoroughly stirred by a stirring paddle, thereby increasing the precipitation rate. At the same time, the scraper on the stirring paddle can scrape off the material on the crystallization tank wall, which can not only prevent agglomeration but also reduce material residue during discharge. Furthermore, the crystallization tank is driven to rotate back and forth by a geared motor, thereby increasing the fluidity of the material and further improving the precipitation rate, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an acidification crystallization precipitation instrument, comprising a crystallization tank, a sealing cover fixedly provided on the top of the crystallization tank, a stirring paddle rotatably provided at the bottom of the sealing cover, a plurality of scrapers arranged in a circular array fixedly provided on the stirring paddle, each scraper contacting the inner wall of the crystallization tank, rotating rods fixedly provided on both outer walls of the crystallization tank, a support frame provided at the bottom of the crystallization tank, two rotating rods passing through the support frame and rotatably connected to the support frame, a driving component for driving the rotating rods to rotate fixedly provided on the support frame, a plurality of evenly distributed casters fixedly provided at the bottom of the support frame, and fixed plates provided on both sides of the support frame.

[0007] In a preferred embodiment, a servo motor is fixedly installed at the center of the top of the sealing cover. The bottom end of the output shaft of the servo motor passes through the sealing cover and is fixed to the top of the stirring paddle. By driving the stirring paddle to rotate with the help of the servo motor, the precipitation rate of the acidified crystallization material can be greatly improved.

[0008] In a preferred embodiment, the drive assembly includes a mounting frame fixed to one side of a support frame. A geared motor is fixedly mounted on the mounting frame, and one end of the output shaft of the geared motor is fixed to one of the rotating rods. The geared motor drives the crystallizer to rotate stably, which can further improve the precipitation rate of the acidified crystallization material.

[0009] In a preferred embodiment, both fixing plates have multiple equally spaced rectangular fixing holes on their tops. The multiple rectangular fixing holes can improve the firmness of the fixing plates when they are fixed, thereby improving the stability of the entire instrument.

[0010] In a preferred embodiment, the outer walls on both sides of the support frame are provided with limiting grooves, and two fixing plates are slidably disposed in the two limiting grooves respectively. The fixing plates are fixed to the support frame by fastening bolts, which makes it convenient for workers to quickly adjust the height of the fixing plates.

[0011] In a preferred embodiment, a feed pipe extends through one side of the top of the sealing cap. The feed pipe is located on the side of the servo motor, and a threaded cap is threadedly connected to the top of the feed pipe. The threaded cap seals the feed pipe, preventing dust and impurities in the external environment from affecting the acidification and crystallization precipitation process.

[0012] In a preferred embodiment, a discharge pipe is connected to the center of the bottom of the crystallization tank, and an electromagnetic valve is fixedly installed on the discharge pipe to facilitate the control of the opening and closing of the discharge pipe.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses a servo motor to drive the stirring paddle to rotate, which fully stirs the acidified crystallization material, thereby improving the precipitation rate. At the same time, the scraper on the stirring paddle can scrape off the material on the crystallization tank wall, which can not only prevent agglomeration, but also reduce material residue during discharge. In addition, the geared motor drives the rotating rod to make the crystallization tank reciprocate inside the support frame, which can increase the fluidity of the material and further improve the precipitation rate.

[0015] 2. The support frame is moved by multiple casters, which improves the flexibility of the entire instrument. At the same time, the staff can adjust the height of the fixed plate and connect it to the ground to improve the stability of the instrument when it is stationary. Attached Figure Description

[0023] Refer to the instruction manual appendix Figures 1-5This utility model provides an acidification crystallization precipitation instrument, including a crystallization tank 1. A sealing cover 2 is fixedly provided on the top of the crystallization tank 1, and a stirring paddle 3 is rotatably provided at the bottom of the sealing cover 2. Multiple scrapers 4 are fixedly provided on the stirring paddle 3 in a ring array. Each scraper 4 is in contact with the inner wall of the crystallization tank 1. Rotating rods 5 are fixedly provided on both outer walls of the crystallization tank 1. A support frame 6 is provided at the bottom of the crystallization tank 1. Both rotating rods 5 pass through the support frame 6 and are rotatably connected to the support frame 6.

[0024] A servo motor 10 is fixedly installed at the top center of the sealing cover 2. The servo motor 10 is a motor that can precisely control the speed, position and torque. It achieves high-precision dynamic adjustment by comparing the command with the actual operating status in real time through a closed-loop feedback system. The bottom end of the output shaft of the servo motor 10 passes through the sealing cover 2 and is fixed to the top of the stirring paddle 3. The servo motor 10 drives the stirring paddle 3 to rotate, thereby improving the precipitation rate of the acidified crystallization material.

[0025] A feed pipe 13 extends through one side of the top of the sealing cover 2. The feed pipe 13 is located on one side of the servo motor 10, and a threaded cap 14 is threadedly connected to the top of the feed pipe 13. The threaded cap 14 seals the feed pipe 13, preventing dust and impurities in the external environment from affecting the acidification and crystallization precipitation process. At the same time, a discharge pipe 15 is connected to the center of the bottom of the crystallization tank 1. A solenoid valve 16 is fixedly installed on the discharge pipe 15, which facilitates the control of the opening and closing of the discharge pipe 15.

[0026] The support frame 6 is fixedly provided with a drive assembly 7 for driving the rotating rod 5 to rotate. The drive assembly 7 includes a mounting frame 71, which is fixed to one side of the support frame 6. A geared motor 72 is fixedly provided on the mounting frame 71. The geared motor 72 is a power transmission device that integrates an electric motor and a reducer. Its main function is to reduce the speed and increase the torque. One end of the output shaft of the geared motor 72 is fixed to one of the rotating rods 5. By using the geared motor 72 to drive the crystallization tank 1 to rotate back and forth, the precipitation rate of the acidified crystallization material can be further improved.

[0027] In actual use, the acidified crystallization material is first added into the crystallization tank 1 through the feed pipe 13. Then, the servo motor 10 drives the stirring paddle 3 to rotate, so that the material is fully stirred. At the same time, the multiple scrapers 4 on the stirring paddle 3 can scrape off the material on the wall of the crystallization tank 1 to avoid clumping. During discharge, the scrapers 4 can reduce material residue. In addition, during the stirring process, the geared motor 72 drives the rotating rod 5 to drive the crystallization tank 1 to reciprocate inside the support frame 6, which intensifies the fluidity of the material in the crystallization tank 1 and further improves the precipitation rate.

[0028] Refer to the instruction manual appendix Figure 1 , Figure 4 and Figure 5 The support frame 6 is fixed with a plurality of evenly distributed casters 8 at its bottom. The support frame 6 is provided with fixing plates 9 on both sides. The top of the two fixing plates 9 is provided with a plurality of equally spaced rectangular fixing holes 11. The outer walls of both sides of the support frame 6 are provided with limiting grooves 12. The two fixing plates 9 are slidably disposed in the two limiting grooves 12 respectively, and the fixing plates 9 are fixed to the support frame 6 by fastening bolts.

[0029] By setting multiple casters 8 at the bottom of the support frame 6, and selecting casters 8 with brakes, it is convenient for staff to flexibly adjust the position of the entire instrument. When acidification and crystallization precipitation work is required, staff can loosen the fastening bolts between the fixing plate 9 and the support frame 6, then push the fixing plate 9 down to contact the ground, and then use bolts to pass through the rectangular fixing hole 11 to connect with the ground. This can improve the stability of the entire instrument when it is stationary.
