[0002] Water-soluble chitosan is a special form of chitosan, which is soluble in water. It improves the solubility of ordinary chitosan, making it more convenient to use and more widely used. Water-soluble chitosan is a chitosan derivative with strong cationic properties, which can promote the absorption of nutrients or drugs by body cells.

[0003] In the process of producing water-soluble chitosan, filtration is an important step. Filtration is mainly used to separate and purify chitosan and remove impurities and insoluble substances. At present, the filtration of water-soluble chitosan is mostly carried out through a filter mechanism. However, in actual use, water-soluble chitosan has a certain viscosity and is easy to adhere to the filter membrane during the filtration process, causing blockage; at the same time, the traditional water-soluble chitosan filtration mechanism is difficult to maintain after clogging, which affects the filtration effect.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5 A filtering device for producing water-soluble chitosan includes a filter cartridge 1, a heating column 21 is installed inside the filter cartridge 1 through a partition 10, a fine mesh filter cartridge 7 is sleeved on the outer side away from the heating column 21, an electric sealing door 11 is arranged obliquely below the fine mesh filter cartridge 7, a filter screen 6 is arranged below the electric sealing door 11, a guide slope 9 is obliquely arranged below the filter screen 6, and a discharge port 12 is arranged on one side of the guide slope 9.

[0025] The filter cartridge 1 is fixed to one side of the upper part of the mounting platform 5, and a sealing cover 4 is rotatably mounted on one side of the outer portion of the filter cartridge 1. The sealing cover 4 is connected to the inside of the filter cartridge 1, and a handle 41 is provided on the sealing cover 4. The sealing cover 4 can be quickly opened by the handle 41, and the filter screen 6 inside can be taken in and out.

[0026] Furthermore, a heater assembly 2 is provided on one side of the outside of the filter cartridge 1, and a discharge port 12 is provided at the bottom of the other side.

[0027] Furthermore, a cover body 3 is installed on the upper part of the filter cartridge 1 , and a feed opening 31 is provided in the middle of the cover body 3 , and the feed opening 31 is communicated with the interior of the filter cartridge 1 .

[0028] Furthermore, a boss is provided in the middle of the partition 10, a heating column 21 is installed in the middle of the boss, the heating column 21 is connected to the heater assembly 2, and a circle of grooves is provided on the outer side of the boss, and a fine mesh filter cartridge 7 is embedded and installed in the groove.

[0029] Furthermore, a plurality of slots are provided on the outer side of the partition 10, and an electric sealing door 11 is rotatably installed in the slot, and the electric sealing door 11 rotates downward to open.

[0030] Furthermore, a clamping seat 8 is installed on one side of the middle of the filter cartridge 1, a slot is opened in the middle of the clamping seat 8, and convex balls 81 are arranged on both sides of the inner wall of the slot, wherein the filter screen 6 is clamped and installed in the middle of the clamping seat 8 through a clamping block 62.

[0031] Furthermore, a clamping block 62 is provided on one side of the filter 6, and arc-shaped notches are opened on both sides of the clamping block 62, which are correspondingly clamped with the convex balls 81, and an extrusion block 61 is provided on the other side of the filter 6, and the extrusion block 61 is in extrusion contact with the inner wall of the sealing cover 4.

[0032] In the present embodiment, the processed chitosan material is poured into the interior of the filter cartridge 1 through the discharge port 31 in the middle of the cover body 3, and the discharge port 31 is directly above the fine mesh filter cartridge 7. At this time, the temperature of the chitosan is relatively low and its viscosity is relatively high, so that all the chitosan material is accumulated inside the fine mesh filter cartridge 7. At this time, the heater assembly 2 controls the heating column 21 to heat, and the temperature of the chitosan material inside is increased and its viscosity is reduced. After heating for a period of time, the material is slowly filtered and discharged through the fine mesh filter cartridge 7, thereby achieving a preliminary filtering operation.

[0034] During actual use, the sealing cover 4 is unlocked and opened by holding the handle 41. At this time, the internal filter screen 6 is pulled to remove the filter screen 6 from the inside of the filter cartridge 1. The filter screen 6 is maintained to alleviate the blockage and ensure the filtering effect. At the same time, the new filter screen 6 is inserted into the clamping seat 8 inside the filter cartridge 1 through the clamping block 62. The arc-shaped opening on the clamping block 62 is firmly clamped with the convex ball 81 on the clamping seat 8. The sealing cover 4 is closed so that the sealing cover 4 squeezes and fixes the extrusion block 61 to ensure the installation stability of the filter screen 6.

[0035] Among them, it is worth noting that the specific closing operation of the electric sealing door 11 is achieved by driving the sealing door plate to rotate by the driving motor. The specific driving principles and methods described in detail in the above specification are technical common sense well known to technical personnel in this field, so they will not be elaborated.

[0036] In the utility model, by setting the heater assembly 2, the heating column 21 and the fine mesh filter cartridge 7, the chitosan can be preliminarily heated to increase its filtration speed, and preliminarily filtered through the filter cartridge, while the electric sealing door 11 is opened to continue to introduce the chitosan into the filter mesh 6 at the bottom for filtration.

[0037] During actual use, the internal filter screen 6 can be taken out by opening the sealing cover 4 on the outside of the filter cartridge 1. The filter screen 6 can be quickly installed into the inside of the filter cartridge through the setting of the snap-fit ​​block and the extrusion block, and fixed and stabilized by the sealing cover, thereby improving the maintenance efficiency of the filter screen and ensuring the filtering efficiency.
