Description

Technical Field

[0001] The utility model relates to the technical field of bone gelatin preparation, and specifically to a device for regulating the pH value of a soaking liquid. Background Art

[0002] The acid leaching process is an important part of the preparation process of bone gelatin, which is used to remove inorganic minerals in the aggregate, such as tricalcium phosphate (Ca3(PO4)2) and calcium carbonate (CaCO3), thereby improving the quality and yield of gelatin. The acid leaching process mainly uses hydrochloric acid as the acid source, and converts the inorganic matter in the aggregate into soluble salts through chemical reactions, thereby achieving separation from collagen. However, a too high pH value in the acid leaching process may reduce the efficiency of acid leaching, because the acid leaching process usually relies on an acidic environment to dissolve minerals in the bone, such as calcium and phosphorus; on the other hand, an increase in pH may cause certain metal ions to form insoluble hydroxide precipitates, such as Fe 3+ Fe(OH)3 precipitation is generated, which will wrap up some valuable components such as vanadium in the bones, making them unable to be effectively leached, thereby increasing the loss rate. Therefore, it is usually necessary to adjust the pH of the soaking solution during the acid leaching process. Utility Model Content

[0031] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the specification of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] See also Figure 1-Figure 2 The present invention provides a device for regulating the pH of a soaking liquid. In practical application, the device injects fresh soaking liquid during the soaking liquid circulation process to adjust the pH of the original soaking liquid. The device comprises a three-way flow guide 1, a retaining frame 2 disposed within the three-way flow guide 1, a main shaft 3 movably connected to the retaining frame 2, and guide fins 4 disposed on the main shaft 3. It should be noted that the fresh soaking liquid can be any of an acidic soaking liquid, an alkaline soaking liquid, and deionized water.

[0034] In some embodiments, the three-way flow guide 1 is a connecting pipe having three flow guide ports, wherein the three-way flow guide 1 includes two groups of flow guide covers 11 and a accommodating tube 12 connected between the two groups of flow guide covers 11, and the accommodating tube 12 is arranged perpendicular to the two groups of flow guide covers 11. In some embodiments, the two groups of flow guide covers 11 are used for circulating the soaking liquid, and the accommodating tube 12 is used to add fresh soaking liquid to the circulating soaking liquid and mix it with the original soaking liquid, thereby achieving the function of adjusting the pH value of the soaking liquid.

[0035] In some embodiments, the flow guide cover 11 is a funnel-shaped structure to facilitate guiding the soaking liquid into the accommodating tube 12 or draining the soaking liquid from the accommodating tube 12. The accommodating tube 12 is a hollow structure, and its two sides are respectively connected to the flow guide cover 11. By arranging the retaining frame 2 in the accommodating tube 12, the retaining frame 2 divides the hollow structure of the accommodating tube 12 into a flow guide chamber 13 and a mixing chamber 14, wherein the flow guide chamber 13 is connected to the flow guide cover 11.

[0036] In some embodiments, the guide fins 4 are provided on the main shaft 3 and are located in the guide chamber 13 . When the soaking liquid flows through the guide chamber 13 , the main shaft 3 is driven to rotate under the action of the guide fins 4 .

[0037] In some embodiments, the pH adjustment device of the soaking liquid also includes: a liquid filling tank 5, an arc tube 6 connected to the liquid filling tank 5, a sleeve 7 connected to the main shaft 3, an inward-rotating piston 8 adapted to the sleeve 7, and a booster blade 9 provided on the sleeve 7, wherein the inward-rotating piston 8 is adapted to the arc tube 6 and is used to adjust the connectivity state of the arc tube 6, and the booster blade 9 is provided in the liquid filling tank 5.

[0038] In some embodiments, the liquid filling tank 5 is also provided with a liquid filling tube 51. When the soaking liquid is added to the soaking liquid pH adjustment device, the soaking liquid first enters the liquid filling tank 5 through the liquid filling tube 51, and then enters the arc tube 6. When the soaking liquid circulates, the inward rotating piston 8 abuts against the end of the arc tube 6 away from the liquid filling tank 5 to block the arc tube 6 to prevent the soaking liquid in the arc tube 6 from entering the mixing tank 14.

[0039] Furthermore, the shaft sleeve 7 is movably connected to the main shaft 3 via a spline. In some embodiments, when the main shaft 3 rotates, the shaft sleeve 7 can be driven to rotate following the main shaft 3, thereby driving the booster blades 9 to rotate. When the booster blades 9 rotate, the blades push the soaking liquid to flow backward, and a pressure difference is formed between the leading edge (suction surface) and the trailing edge (pressure surface) of the blades, so that the speed of the soaking liquid is accelerated at the trailing edge of the blades, thereby generating a forward thrust, thereby pushing the shaft sleeve 7 to move in the direction close to the inward rotating piston 8, and then pushing the inward rotating piston 8 to move, so that the inward rotating piston 8 is separated from the arc tube 6.

[0040] In some embodiments, a spring 81 is provided at one end of the inward-rotating piston 8 away from the sleeve 7. When the soaking liquid is in a circulation state, the circulation flow rate of the soaking liquid in the three-way guide member 1 is a first circulation flow rate. Under the limiting action of the spring 81, the inward-rotating piston 8 is in a state of blocking the arc tube 6; when the soaking liquid is in a circulation replenishment state, the circulation flow rate of the soaking liquid in the three-way guide member 1 is a second circulation flow rate, wherein the second circulation flow rate is greater than the first circulation flow rate. By increasing the circulation flow rate of the soaking liquid, as the circulation flow rate of the soaking liquid in the three-way guide member 1 increases, under the action of the guide fin 4, the rotation speed of the main shaft 3 is accelerated, and the thrust generated by the booster blade 9 is greater, thereby compressing the spring 81, so that the inward-rotating piston 8 is separated from one end of the arc tube 6, so that the soaking liquid in the arc tube 6 can enter the mixing chamber 14.

[0041] In some embodiments, a through hole 21 is provided on the retaining frame 2, so that the mixing chamber 14 and the guide chamber 13 are in a connected state, so that the replenished soaking liquid can enter the three-way guide member 1 and mix with the circulating soaking liquid, so that the replenished soaking liquid can be mixed with the circulating soaking liquid by adjusting the flow rate of the circulating liquid, and the replenished soaking liquid plays a role in adjusting the pH value of the soaking liquid.

[0042] Finally, it should be noted that the embodiments disclosed in the present invention are only preferred embodiments of the present invention, which are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
