Description

Technical Field

[0001] The invention mainly relates to the field of resin production, and in particular to a solid-liquid mixing device capable of repeated mixing. Background Art

[0002] Resin usually refers to an organic polymer that softens or melts when heated, tends to flow under external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. In a broad sense, any polymer compound that can be used as a raw material for plastic products is called a resin;

[0003] Resins can be divided into natural resins and synthetic resins. Natural resins refer to amorphous organic substances obtained from secretions of animals and plants in nature, such as rosin, amber, shellac, etc. Synthetic resins refer to resin products obtained by chemical synthesis of simple organic substances or chemical reactions of certain natural products, such as phenolic resins, polyvinyl chloride resins, etc., among which synthetic resins are the main components of plastics;

[0004] The resin production process requires the use of a solid-liquid mixing device to mix the resin with concentrated brine to facilitate long-term storage of the resin.

[0005] The inventor discovered the following defects during the operation of the specific embodiment:

[0006] However, when concentrated brine and resin are directly placed into the solid-liquid mixing device, when the height of the resin is relatively large, the mixing device cannot quickly break up the concentrated brine and the resin, so that the concentrated brine cannot quickly soak the resin, and the resin inside cannot come into contact with the concentrated brine, resulting in improper storage of the resin. At the same time, the resin needs to be rinsed with pure water. When the resins are stacked on each other, the pure water cannot completely come into contact with the resin, resulting in concentrated brine still remaining inside the resin.

[0007] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Summary of the invention

When the resin needs to be stored through the solid-liquid mixing device, the resin is placed in the lifting bin 905, and then the lifting bin 905 is placed in the storage bin 901. Then the water pump allows the concentrated brine to enter the lifting bin 905 through the water inlet pipe 4, and the driving structure is started to drive the spring telescopic rod 909 to rotate. The spring telescopic rod 909 drives the stirring plate 913 to mix the concentrated brine and the resin inside, so that the concentrated brine contacts the resin, thereby facilitating the subsequent mixing of the resin. The resin is stored in the storage tank.

At the same time, the water pump sends pure water into the lifting bin 905 to rinse the resin with pure water. The resin and pure water are mixed by rotating the stirring plate 913 to dilute the concentrated brine inside the resin to avoid direct contact between the resin and the pure water to cause the resin to expand and break.

[0040] Furthermore, downpipes 2 are provided on both sides of the bottom of the mixing shell 1, electric telescopic rods 10 are provided on both sides of the outer wall of the mixing shell 1, and top covers 11 are provided on the tops of the two electric telescopic rods 10.

The meshing gear 19 drives the rotating ring 801 to rotate through the first gear ring 802. The rotating ring 801 drives the resin mixing structure 9 on the outer wall to rotate, so that the rolling wheel 907 on the outer wall of the lifting bin 905 inside the placement bin 901 slides on the top of the guide bar 3, so that the concentrated salt water inside the lifting bin 905 can be discharged.

[0042] Further, the first driven gear 14 is rotatably connected to the top of the top cover 11, the number of the first driven gears 14 is set to be multiple, and the multiple first driven gears 14 are arranged in a ring array on the top of the top cover 11. The outer walls of the multiple first driven gears 14 are meshed with a second gear ring 15, and the second gear ring 15 is rotatably connected to the top cover 11. The first driven gear 14 is meshed and connected with the driving gear 13. A magnetic device 20 is arranged directly below the first driven gear 14. The driving gear 13 drives the first driven gear 14 to rotate, and the first driven gear 14 drives other gears through the second gear ring 15.

The magnetic device 20 and the magnet plate 910 have the same principle as the magnetic stirrer, and when the lifting bin 905 is located at the bottom and the top, it can contact the magnetic device 20 at different positions, so that the spring telescopic rod 909 can be driven.

The installation shaft 911 on the outer wall of the spring telescopic rod 909 is rotatably connected to the spring telescopic rod 909, so that when the spring telescopic rod 909 rotates, the bevel gear 912 meshes and rotates with the outer wall of the inner bevel gear ring 904, causing the installation shaft 911 to rotate, and the installation shaft 911 drives the stirring plate 913 to rotate to stir the resin inside the lifting bin 905.

[0047] The steps for pretreatment of cation resin are as follows:

[0048] First, a water pump is used to send concentrated salt water into the interior of the lifting chamber 905 through the water inlet pipe 4, and the amount is about twice the volume of the resin to be treated. The resin is placed in the salt solution of the lifting chamber 905 and soaked for 18-20 hours, and the concentrated salt water and resin in the lifting chamber 905 are stirred by the stirring plate 913. Then, the rotating structure 8 drives the lifting chamber 905 to move upward, so that the filter baffle 906 fits with the water outlet trough 902, so that the concentrated salt water in the lifting chamber 905 is discharged, and the water pump uses pure water to send it into the interior of the lifting chamber 905 to clean the resin.

After the lifting chamber 905 moves upward to drain the alkali solution, the resin is rinsed until the discharged water is close to neutral. Then 5% hydrogen chloride solution is used in the same amount as above, and it is soaked for 4-8 hours, and the acid is drained, and it is drifted with clean water until it is neutral for use. During the steps of rinsing and soaking the lifting chamber 905, the stirring plate 913 needs to mix the resin and different liquids.
