Description

Technical Field

[0001] This application relates to the field of pigment processing equipment technology, and in particular to a solvent pigment vacuum drying and concentration device. Background Technology

[0002] Solvent pigment vacuum drying and concentration equipment is often used to concentrate the solvent or other liquid components in pigments to obtain purer and more concentrated pigments. This process can be achieved through different technologies and equipment, depending on the properties of the pigment and the extraction requirements.

[0003] A search revealed a patent document with authorization announcement number CN222427153U, which discloses a concentration device for pigment extraction. The device includes a concentration chamber, with a shell fixedly installed on the outer top of the chamber. A steam inlet is connected to the left side of the top of the shell, and a steam outlet is connected to the right side of the bottom of the shell. A feed pipe is fixedly installed on the left side of the top of the concentration chamber. This device utilizes the concentration chamber, shell, steam inlet, steam outlet, and reflux pipe in conjunction. After the pigment solvent is heated by high-temperature steam, the water in the solvent evaporates into water vapor. When the high-temperature steam flows through a cold water chamber, since the middle of the cold water chamber is located inside the shell, the gas in the high-temperature steam can be recovered through the shell for waste heat recovery, thus achieving energy saving.

[0004] In practical use, it has been found that existing devices only stir the solvent pigments in one direction when drying and concentrating them, resulting in a long mixing and dispersion time. At the same time, the discharge pipe cannot be cleared, which leads to problems affecting discharge efficiency and work efficiency. Therefore, we propose a vacuum drying and concentration device for solvent pigments to solve the above problems. Utility Model Content

[0041] Specifically, the unblocking mechanism includes an unblocking shaft 501 and an unblocking rod 502. The same unblocking shaft 501 is rotatably installed on the inner left side of the functional box 2 and the inner right side of the discharge pipe 5.

[0042] Specifically, the second transmission mechanism includes two second transmission wheels 204 and a second transmission belt 205.

The second transmission wheels 204 are located to the left of the first transmission wheel 202, and the same second transmission belt 205 is sleeved on both second transmission wheels 204.

[0043] Specifically, the vacuum mechanism includes a vacuum pump 6 and an extraction pipe. The vacuum pump 6 is located on the right side of the concentration tank 1, and an extraction pipe is installed between the vacuum pump 6 and the concentration tank 1. The extraction pipe is located below the partition 3, and a liquid storage mechanism is installed between the vacuum pump 6 and the concentration tank 1.

[0044] Specifically, the liquid storage mechanism includes a condenser 601 and a water tank 7. The water tank 7 is located on the right side of the concentration tank 1 and is located below the vacuum pump 6. The same condenser 601 is provided between the water tank 7 and the vacuum pump 6.

The heater 901, vacuum pump 6, motor 4, solenoid valve and controller 9 are electrically connected.

[0046] In this application, during operation, the solvent pigment to be processed is first fed into the space below the partition 3 of the concentration tank 1 through the feed pipe 10. The operator starts the motor 4 through the controller 9 on the front side of the function box 2. The output shaft of the motor 4 can drive the first stirring shaft 101 to rotate, which can drive the first stirring rod 102 to rotate, so that the solvent pigment below the partition 3 can be stirred by the first stirring rod 102, which can achieve the purpose of promoting the initial mixing of pigment and solvent. At the same time, the first stirring shaft 101 can drive the rotating shaft 201 to rotate through two bevel gears 8.

This can achieve the purpose of acting on the material from different directions and angles, which greatly improves the uniformity of stirring and improves the mixing and dispersion efficiency of solvent pigment.

[0047] While stirring, controller 9 activates heater 901 installed in front of concentration tank 1 to heat the material inside, thereby increasing the material temperature and accelerating solvent evaporation. Simultaneously, controller 9 activates vacuum pump 6 located on the right side of concentration tank 1 to extract air from the tank through the suction pipe, creating a vacuum environment. This vacuum environment lowers the solvent boiling point, allowing for faster evaporation of the solvent pigments and significantly accelerating the drying and concentration process. The solvent vapor generated during evaporation enters condenser 601 via vacuum pump. Inside condenser 601, the vapor liquefies upon cooling, forming liquid solvent, which flows into water tank 7 located below vacuum pump 6, enabling solvent recovery and reuse.

[0048] After the solvent pigment has finished drying and concentrating, the controller 9 opens the solenoid valve on the discharge pipe 5. At this time, the second stirring shaft 103 drives the unblocking shaft 501 and the unblocking rod 502 to rotate through the two second transmission wheels 204 and the second transmission belt 205. This enables the unblocking rod 502 to stir and unblock the pigment in the discharge pipe 5, effectively preventing the dried pigment from clogging the discharge pipe 5 during the discharge process, ensuring that the dried pigment can be discharged smoothly, and thus improving work efficiency.
