[0019] As a preferred embodiment of a carrageenan extraction multi-stage filter, the pressurization assembly includes an outlet pipe, a self-priming booster pump, a base, an inlet pipe, and a water tank.

The outlet of the self-priming booster pump is fixedly connected to one end of the outlet pipe, and the other end of the outlet pipe is fixedly connected to the inlet of the spray frame.

[0020] Using the above solution, the base is used to provide stable support for the self-priming booster pump. The self-priming booster pump draws water from the water tank into the pump through the inlet pipe, pressurizes it, and then delivers the pressurized water to the nozzle through the outlet pipe. The pressurized water then enters the spray frame, making the water sprayed from the spray frame more impactful and more effectively cleaning the impurities remaining on the inner wall.

[0024] Using the above scheme, the atomizing nozzle sprays water downwards to flush and clean the inner wall of the filter channel formed by the connection of outer shell 1, outer shell 2 and outer shell 3.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] By setting up a slurry distribution assembly, the motor drives the hopper and the discharge pipe to reciprocate. The hopper and the discharge pipe are connected to form a discharge channel. The carrageenan liquid is discharged from the discharge pipe through the discharge channel. The discharge pipe discharges the carrageenan liquid onto the filter plate in the filter assembly while reciprocating. This can make the carrageenan liquid evenly distributed. The evenly distributed carrageenan liquid can make its surface evenly stressed, avoid the dead corners caused by the accumulation of liquid, reduce manual intervention, and improve production efficiency.

[0027] The carrageenan solution is filtered by setting up filter assembly one and filter assembly two. The carrageenan solution is filtered once by filter plate one in filter assembly one, which removes fine debris, impurities, and agglomerated substances. Then it enters filter plate two in filter assembly one for a second filtration, which removes any remaining fine debris, impurities, and agglomerated substances. Then it enters filter plate three in filter assembly two for a third filtration, which removes any remaining fine debris, impurities, and agglomerated substances. When filter plates one, two, and three need to be cleaned, simply open outer door one and outer door two and remove filter plates one, two, and three for cleaning and maintenance.

[0028] After three filtration processes, the carrageenan solution is made purer, effectively avoiding the adverse effects of impurities on the product's color, transparency, and physicochemical properties, thus improving the product's quality level. When the filter plate needs to be removed for cleaning and maintenance, the disassembly process is simple and quick, shortening the operation time and saving overall time costs.

[0029] By setting up a pressurization component, water is drawn into a self-priming booster pump for pressurization. The pressurized water is then delivered to the spray frame through the outlet pipe. When the atomizing nozzles in the spray frame flush and clean the impurities on the inner wall of the filter channel formed by the connection of outer shell 1, outer shell 2, and outer shell 3, they have a certain impact force, which more effectively removes the impurities attached to the inner wall of the filter channel.

[0030] The stable water pressure provided by the self-priming booster pump can avoid uneven water output from the nozzles due to water pressure fluctuations. The atomizing nozzles have high medium utilization, even water distribution, and a large spray area, avoiding excessive or insufficient water spray in some areas and reducing water waste.

The filter pores of the third outer shell 32 are smaller than those of the first outer shell 28 and the second outer shell 24, which further removes fine debris, impurities, and agglomerated substances from the carrageenan liquid.

The support column 53 provides support for the panel 51, ensuring the stability of the panel 51. The panel 51 provides an installation platform for the filter assembly 2 3 and the pressurization assembly 4, and ensures stability. A discharge port 52 is opened on one side of the panel 51. The discharge port 52 is located below the outer shell 31 in the filter assembly 2 3. The inner wall of the outer shell 31 and the discharge port 52 are connected to form a discharge channel. The carrageenan liquid that has been filtered three times falls from the discharge port 52 into a container prepared in advance by the operator below the discharge port 52 through the discharge channel. The carrageenan is filtered and the motor 18 is turned off to prepare for the next operation.
