Description

Technical Field

[0001] This utility model relates to the field of tributyl phosphate solution purification, and in particular to a mixing device for tributyl phosphate solution purification. Background Technology

[0002] Tributyl phosphate (TBP) is an important organic compound widely used as a solvent, extractant, plasticizer, and defoamer. Due to the high purity requirements for its applications, the purification of tributyl phosphate solutions is a crucial process step.

[0003] In the purification process of tributyl phosphate, the mixing device is an indispensable part. It is mainly used to ensure thorough mixing of tributyl phosphate with the alkaline solution, thereby effectively neutralizing residual acidic impurities in the tributyl phosphate. However, the design of traditional mixing devices has certain limitations. The agitator is usually fixed inside the device. While this design provides good mixing during operation, it brings many inconveniences during regular maintenance. Because the agitator obstructs the inner wall of the device, cleaning and replacing the agitator itself becomes extremely difficult. Simultaneously, the maintenance and cleaning of the inner wall of the device are also hindered. Utility Model Content

[0027] The present invention can be explained in more detail through the following embodiments. The present invention is not limited to the following embodiments. The purpose of disclosing the present invention is to protect all changes and improvements within the scope of the present invention.

[0028] Combined with appendix Figures 1-6 The mixing device for purifying tributyl phosphate solution includes a housing 1; and further includes: a top cover 3, which is located at the top opening of the housing 1 and has a feeding port 301; a stirring blade 8, with a shaft 7 located below the top cover 3 and rotatably connected to the top cover 3, the stirring blade 8 having a suspension part and being connected to the bottom end of the shaft 7 by screws 9; a telescopic assembly 5, which is arranged in a circular array below the periphery of the top cover 3; and a drive mechanism 6, on which several of the telescopic assemblies 5 are connected.

[0029] During the purification process of tributyl phosphate solution, when deacidification is carried out, tributyl phosphate and sodium hydroxide are added through the feed port 301 and stirred and mixed inside the shell 1.

[0030] like Figure 1-2 As shown, an end plate 101 is provided at the top edge of the housing 1, and a sealing gasket is provided at the bottom edge of the top cover 3.

[0031] When stirring and mixing, the top cover 3 is in the closed state, such as... Figure 1 As shown, the sealing gasket provides a seal between the top cover 3 and the housing 1; when the entire device is cleaned and maintained regularly, the top cover 3 can be opened by the telescopic component 5 and the drive mechanism 6, so that the stirring blade 8 and the shaft 7 can be separated from the housing 1, making it convenient for manual cleaning of the stirring blade 8, the shaft 7 and the housing 1.

[0032] like Figure 1-2 As shown, a first motor 4 is fixedly installed on the top of the top cover 3, and the output shaft end of the first motor 4 is connected to the top end of the shaft body 7.

[0033] The first motor 4 is used to drive the shaft 7 and the stirring blades 8 to rotate together, so as to stir the material inside the shell 1 and mix it.

[0034] like Figure 6As shown, the bottom end of the shaft 7 has a bottom groove 701, the middle of the stirring blade 8 has a rod 801, and the top of the rod 801 has a socket 802, which is inserted into the bottom groove 701. The suspension part includes a pin 10. The bottom end of the shaft 7 and the socket 802 have a first horizontal hole 703 and a second horizontal hole 804, respectively, which are inserted into the first horizontal hole 703 and the second horizontal hole 804. The bottom end of the shaft 7 has a plurality of mounting holes 702 arranged in a ring array around its perimeter, and the mounting holes 702 communicate with the bottom groove 701. The socket 802 has a plurality of screw holes 803 arranged in a ring array around its perimeter. One end of the screw 9 is inserted into the mounting hole 702, and the other end of the screw 9 is threaded into the screw hole 803.

[0035] When it is necessary to replace the stirring blade 8, the stirring blade 8 can be disassembled by unscrewing all the screws 9 and then pulling out the pin 10. When replacing the new stirring blade 8, the socket 802 is inserted into the bottom groove 701, the first horizontal hole 703 and the second horizontal hole 804 are aligned, the pin 10 is inserted into the first horizontal hole 703 and the second horizontal hole 804, so that the stirring blade 8 is in a suspended state, and then the screws 9 are installed by screwing the screws 9 into the screw holes 803 to complete the installation.

[0036] In the above installation structure, the stirring blade 8 is pre-installed by suspending it before the screw 9 is installed by setting the pin 10, the first horizontal hole 703 and the second horizontal hole 804. By suspending it, the stirring blade 8 does not need to be manually lifted during the installation of multiple screws 9. At the same time, the stirring blade 8 does not need to be lifted when the screw 9 is removed, so as to prevent it from falling.

[0037] like Figure 2-5As shown, the telescopic component 5 includes a movable sleeve 501; the top end of the movable sleeve 501 is fixedly connected to the bottom edge of the top cover 3; a guide hole 102 is provided on the end plate 101, and the movable sleeve 501 is engaged with the guide hole 102; the movable sleeve 501 has a threaded groove along its length, and a stud 502 is threadedly connected to the threaded groove. The movable sleeve 501 has a square cross-section, and an end seat 503 is fixedly fitted onto the bottom end of the movable sleeve 501. The driving mechanism 6 includes an annular shell 601. Multiple fixing brackets 602 are fixedly installed on the outer wall of the inner ring of the annular shell 601. The fixing brackets 602 are fixedly connected to the support legs 2. An external gear ring 604 and multiple driven gears 605 are disposed inside the annular shell 601. The external gear ring 604 is rotatably sleeved onto the inner wall of the inner ring of the annular shell 601. All driven gears 605 are rotatably installed inside the annular shell 601 and mesh with the external gear ring 604. The external gear ring 604 also meshes with a driving gear 606, which is rotatably installed inside the annular shell 601. A second motor 603 is fixedly installed on the top of the annular shell 601. The output shaft end of the second motor 603 is connected to the driving gear 606. The multiple driven gears 605 are respectively connected to the bottom ends of the studs 502 of multiple telescopic components 5. The studs 502 and the threaded grooves use triangular threads, which have good self-locking properties.

[0038] The top cover 3 is raised and lowered via the telescopic assembly 5 and the drive mechanism 6 to open and close. The specific process is as follows: the second motor 603 drives the drive gear 606 to rotate. The drive gear 606 meshes with the external gear ring 604, causing the external gear ring 604 to rotate. The external gear ring 604 meshes with the driven gear 605, causing multiple driven gears 605 to drive multiple studs 502 of the telescopic assembly 5 to rotate synchronously. When the stud 502 rotates, it engages with the threaded groove for threaded transmission. With the guidance provided by the movable sleeve 501 and the guide hole 102, the movable sleeve 501 moves up and down, thereby driving the top cover 3 to move up and down, achieving lifting and lowering adjustment.

[0039] like Figure 4 As shown, a plurality of support feet 2 are fixedly installed at the bottom of the housing 1, and a discharge port is provided at the bottom of the housing 1.

[0040] The support foot 2 is used to support the housing 1 and provides a mounting position for the drive mechanism 6, while the discharge port is used to discharge the mixed materials; a valve is installed at the discharge port to control the opening and closing of the discharge port.
