Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a preparation process and equipment of cellulose citrate phthalate, which solves the problem of the traditional preparation process and equipment of cellulose citrate phthalate in the esterification process. , will generate heat, which will inhibit the esterification reaction process. At the same time, the heat generation will cause thermal fatigue to the equipment components, resulting in the inability of the components to work continuously for a long time and affecting the progress of the processing.

Embodiment 1

[0047] see Figure 1-7 , the present invention provides a technical solution: a preparation equipment for cellulose citrate phthalate, specifically comprising:

[0048] Material guide plate 1, the material guide plate 1 has a circular box, and the fan 2 installed on the right side of the outer surface of the material guide plate 1, and installed on the front and back rail slide bars 3 of the top of the circular box body, and installed on the The support slip ring 4 on the top of the track slide bar 3, and the esterification equipment 5 installed on the inner surface of the support slip ring 4, and the arc strut 6 installed on the top of the esterification equipment 5, and installed on the top of the arc strut 6 The hemispherical tank 7 provides the source of driving force for the overall equipment through the setting of the fan 2, reduces the contact area of ​​the equipment components, and at the same time reduces the heat generated by the equipment itself when the equipment i...

Embodiment 2

[0060] see Figure 1-7 On the basis of Example 1, the present invention provides a technical solution: a preparation process of cellulose citrate phthalate, comprising the following steps,

[0061] Step 1: Fill the hemispherical material tank 7 with citric acid, and fill the cellulose through the injection pipe 56 at the same time, so that the cellulose is infused into the inner cavity of the esterification spherical shell 52 through the sealing ring 562;

[0062] Step 2: Push the esterification device 5 along the track slide bar 3 through the support slip ring 4, so that the esterification device 5 is located directly above the fan 2;

[0063] Step 3: Start the fan 2 to infuse the air flow, the air flow rises along the protective tube 51, the air flow rises from the outer surface of the esterification spherical shell 52, blows the air flow fan blade 552, and the air flow fan blade 552 is driven to rotate by the air flow;

[0064] Step 4: The air flow fan blade 552 drives the...

Abstract

The invention discloses a preparation process and equipment of citric acid cellulose phthalate, and the preparation process specifically comprises the following steps: 3, starting a fan to enable airflow to be infused and blow airflow fan blades; 4, driving a mixing main pipe to rotate by the airflow fan blades to enable a mixing ball to rotate along with a joint pipe and the mixing main pipe, 5, enabling the mixing ball to rotate to drive a sealing rod to extend out along the branch flow guide pipe through centrifugal force, opening a filling hole, and enabling that citric acid in the hemispherical material tank flows out through the filling hole; and 6, enabling that citric acid and cellulose are continuously mixed and reacted through rotation of the mixing ball. The invention relates to the technical field ofcitric acid cellulose. A driving force source is provided for the whole equipment through the arrangement of the fan, heat generated by the equipment during working is reduced, thermal fatigue damage to equipment components caused by too high heat is avoided, air flow is promoted through the arrangement of the fan, the situation that heat generated in the esterification process cannot be dissipated in time is avoided, and normal proceeding of esterification reaction is guaranteed.

Description

technical field [0001] The invention relates to the technical field of cellulose citrate, in particular to a preparation process and equipment of cellulose citrate phthalate. Background technique [0002] Citric acid is an important organic acid, also known as citric acid, colorless crystal, often contains a molecule of crystal water, odorless, has a strong sour taste, and is easily soluble in water. Its calcium salt is more soluble in cold water than hot water, and this property is often used to identify and separate citric acid. Anhydrous citric acid can be obtained by controlling the appropriate temperature during crystallization. It has many uses in industry, food industry, cosmetic industry, etc. [0003] Cellulose, the main structural component of plant cell walls, is often associated with hemicellulose, pectin, and lignin, and the manner and degree of incorporation greatly influences the texture of foods of plant origin. The texture changes of plants during ripenin...
