Description

Technical Field

[0001] The utility model relates to the technical field of inositol purification, in particular to a crude inositol desalting device. Background Art

[0002] Inositol, chemical name: cyclohexanehexol, is an important vitamin required by higher animals. Inositol can promote fat metabolism and reduce the cholesterol content in the blood. It is also used as an anti-fatty liver drug for the treatment of cirrhosis, hepatitis, high cholesterol, excessive fat and vascular sclerosis. In addition to being used directly as a drug, such as inositol tablets, hepatol, and liver-soothing tablets, inositol is also used as a pharmaceutical intermediate to make many drugs, such as nicotinic acid inositol ester, Maitong, and the anticancer drug paclitaxel.

[0003] Inositol is mostly present in a variety of plants with its precursor phytic acid, such as corn, rice, wheat, etc. At present, the inositol production process generally recycles phytic acid first, then adds lime water to neutralize and generate calcium phytate precipitation, and calcium phytate is then hydrolyzed, neutralized, filtered, concentrated, crystallized, decolorized, recrystallized, and other processes to produce inositol. When using corn soaking water as raw material to produce calcium phytate, due to the high potassium ion content in the corn soaking water, a large amount of potassium salt is entrained in the calcium phytate. Potassium salt is gradually enriched as the feed liquid is concentrated, resulting in a certain amount of potassium salt usually contained in the crude inositol crystals, thereby affecting the quality of inositol. Based on the above problems, it is necessary to provide a device to effectively remove potassium salts in the crude inositol. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example

[0027] like Figure 1 As shown, a crude inositol desalination device comprises a connected inositol crystallization mother liquor storage tank 1, a salt-containing crude inositol storage tank 2, a desalting tank 3, a first centrifuge 4, a purified water storage tank 5, a dissolving tank 6, a candle filter 7, a cooling crystallization tank 8, a second centrifuge 9, a first drying tank 10, and a desalted inositol finished product storage tank 11;

[0028] The inositol crystallization mother liquid storage tank 1 is communicated with the feed port of the desalting tank 3, and a first electromagnetic valve 12 and a first electromagnetic flowmeter 13 are provided on the connecting pipeline between the inositol crystallization mother liquid storage tank 1 and the desalting tank 3, and the first electromagnetic valve 12 and the first electromagnetic flowmeter 13 are interlocked. The first electromagnetic flowmeter 13 can monitor the addition amount of the inositol crystallization mother liquid, and if a certain amount is added, a signal can be transmitted to an external control system (not shown in the figure), and the external control system automatically controls the first electromagnetic valve 12 to close, thereby accurately controlling the addition amount of the inositol crystallization mother liquid in the desalting tank 3.

[0029] The crude salt-containing inositol storage tank 2 is connected to the desalting tank 3 through a bucket elevator 14. A second electromagnetic valve 15 is provided on the pipeline connecting the desalting tank 3 and the bucket elevator 14. A weighing module 16 is provided on the desalting tank 3. The weighing module 16 is interlocked with the second electromagnetic valve 15. The amount of crude salt-containing inositol added to the desalting tank 3 can be calculated by the weighing module 16. If the amount reaches the set value, the weighing module 16 can transmit a signal to the external control system, and the external control system automatically closes the second electromagnetic valve 15, thereby realizing the quantitative addition of the crude salt-containing inositol.

[0030] Through the above arrangement, the crude saline inositol product and the inositol crystallization mother liquor in the desalting tank 3 are fully and evenly mixed after the feeding is completed. Since the inositol in the inositol crystallization mother liquor has reached saturation, the potassium salt in the crude saline inositol product can be dissolved in the inositol crystallization mother liquor, while the inositol in the crude saline inositol product is not dissolved, thereby preliminarily achieving the removal of the potassium salt in the crude saline inositol product.

[0031] The liquid outlet of the desalting tank 3 is connected to the first centrifuge 4, the purified water storage tank 5, the dissolving tank 6, the candle filter 7, the cooling crystallization tank 8, the second centrifuge 9, the first drying tank 10, and the desalted inositol finished product storage tank 11 in sequence. Under the action of the first centrifuge 4, the mother liquor dissolved with potassium salt is separated from the undissolved desalted inositol crude product, and the separated desalted inositol crude product enters the dissolving tank 6. Purified water is added into the dissolving tank 6 so that the desalted inositol crude product and the purified water are fully mixed and dissolved. The obtained liquid is impurity-removed by the candle filter, and the obtained liquid enters the cooling crystallization tank 8 for cooling and crystallization. The crystallized liquid is centrifuged by the second centrifuge 9 to separate the desalted inositol finished wet product, which is dried by the first drying tank 10 and then enters the desalted inositol finished product storage tank 11 for storage.

[0032] Furthermore, in this embodiment, the bucket elevator 14 is a Z-type bucket elevator, which can realize vertical and horizontal transportation, ensure that the material is stable and not tilted during the transportation process, ensure the continuity of the production process, save energy, and improve production efficiency.

[0033] Furthermore, in this embodiment, the liquid outlet of the second centrifuge 9 is connected to the activated carbon adsorption column 17, and the discharge port of the activated carbon adsorption column 17 is connected to the inositol crystallization mother liquid storage tank 1. The mother liquid after centrifugation by the second centrifuge 9 can be used as inositol crystallization mother liquid for the next round of desalination of salt-containing crude inositol after decolorization by the activated carbon adsorption column 17, which greatly reduces energy consumption and reduces the amount of wastewater in the desalination process of crude inositol.

[0034] Furthermore, in this embodiment, the liquid outlet of the first centrifuge 4 is connected to the mother liquid tank 18, the open concentration tank 19, and the third centrifuge 20 in sequence, the solid outlet of the third centrifuge 20 is connected to the second drying tank 21 and the potassium salt storage tank 22 in sequence, and the liquid outlet of the third centrifuge 20 is connected to the concentration crystallization tank 23 and the salt-containing inositol crude product storage tank 2 in sequence; a steam coil 24 is provided in the open concentration tank 19; a jacket 25 is provided on the outer side of the third centrifuge 20, and a heat exchange medium inlet 26 and a heat exchange medium outlet 27 are provided on the jacket 25.

[0035] Through the above arrangement, the centrifuged mother liquor of the first centrifuge 4 enters the mother liquor tank 18, and then enters the open concentrating tank 19, steam is introduced into the steam coil 24 to heat the centrifuged mother liquor in the open concentrating tank 19, because the solubility of inositol at high temperature is higher than that of potassium salt, potassium salt is gradually precipitated during the concentration process, and then the feed liquid is subjected to high-temperature centrifugation in the third centrifuge 20 to obtain potassium salt and saline inositol mother liquor, the potassium salt is dried by the second drying tank 21 and then stored in the potassium salt storage tank 22, the saline inositol mother liquor is further concentrated and crystallized by the concentration crystallization tank 23 to obtain a saline inositol wet product, and then enters the saline inositol crude product storage tank 2 for temporary storage, and is used to continue desalting to prepare a desalted inositol finished product.

[0036] Furthermore, in this embodiment, the desalting tank 3, the dissolving tank 6, the first drying tank 10, the second drying tank 21, the cooling crystallization tank 8 and the concentration crystallization tank 23 are all provided with a stirrer 28, which greatly improves the desalting efficiency of the crude inositol.
