Description

Technical Field

[0001] The present invention relates to the technical field of bone gelatin preparation, and in particular to a system and method for monitoring 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. It is used to remove inorganic minerals in the aggregate, such as tricalcium phosphate (Ca3(PO4)2) and calcium carbonate (CaCO3), so as to improve 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.

[0003] However, too high a pH value in the pickling process may reduce the efficiency of pickling, because the pickling process usually relies on an acidic environment to dissolve minerals in bones, such as calcium and phosphorus; on the other hand, an increase in pH may cause some metal ions to form insoluble hydroxide precipitation, 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 necessary to monitor the pH value of the immersion solution during the acid leaching process in real time.

[0004] In the prior art, the pH value of the soaking liquid is usually detected after the soaking liquid is manually extracted to monitor the pH value of the soaking liquid. However, the detection efficiency of the pH value after the soaking liquid is manually extracted is low. On the other hand, the results of the sampling test of the pH value of the soaking liquid cannot reflect the pH value of the soaking liquid as a whole, resulting in low detection accuracy, which will interfere with subsequent monitoring measures.

[0087] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the specification of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0088] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0089] See also Figure 1-Figure 7 In a first aspect, the present invention provides a soaking liquid pH monitoring system, comprising: a reaction device 1, a circulation device 2 connected to the reaction device 1, an injection device 3 connected to the circulation device 2, and a detection device 4 connected to the injection device 3.

[0090] In some embodiments, the reaction device 1 is a reaction container for accommodating the soaked object for soaking. Specifically, the reaction device 1 includes: a reaction tank 11, and a metal grid frame 12 arranged in the reaction tank 11. In some embodiments, the reaction tank 11 is used to accommodate the soaked object and the soaking liquid, so as to realize the soaking process of the soaked object. In some embodiments, the metal grid frame 12 is horizontally arranged in the reaction tank 11. On the one hand, the metal grid frame 12 is used to support the soaked object, and on the other hand, it can also play a role in assisting in salvaging the soaked object.

[0091] In some embodiments, the reaction device 1 further includes a first replenishing tank 13, a first replenishing pipe 14 connected to the first replenishing tank 13, a second replenishing tank 15, and a second replenishing pipe 16 connected to the second replenishing tank 15. In some embodiments, the first replenishing tank 13 and the second replenishing tank 15 are used to accommodate soaking liquid, for example, the first replenishing tank 13 and the second replenishing tank 15 may contain at least one of an acidic soaking liquid, an alkaline soaking liquid and deionized water, and the first replenishing pipe 14 and the second replenishing pipe 16 are also connected to the liquid injection device 3, and are used to replenish the soaking liquid into the liquid injection device 3.

[0092] Furthermore, the bottom of the reaction tank 11 is connected to the circulation device 2, and the bottom of the reaction tank 11 is a funnel-shaped structure that is wide at the top and narrow at the bottom, so that the soaking liquid can enter the circulation device 2, thereby realizing the circulation of the soaking liquid.

[0093] In some embodiments, the circulation device 2 is used to keep the soaking liquid circulating. By keeping the soaking liquid in the reaction tank 11 circulating, the soaking liquid in the reaction tank 11 is mixed evenly, thereby maintaining uniform pH of the soaking liquid and uniform interlayer temperature.

[0094] Furthermore, the circulation device 2 includes: a four-way pipe 21, and first solenoid valves 22 respectively arranged on the four-way pipe 21, wherein the four-way pipe 21 is a connecting pipe having four independent interfaces, and a first solenoid valve 22 is arranged on each interface of the four-way pipe 21, and the first solenoid valve 22 is used to adjust the connectivity status of each interface of the four-way pipe 21.

[0095] In some embodiments, one of the interfaces of the four-way pipe 21 is connected to the bottom of the reaction device 1. Furthermore, the circulation device 2 also includes a pump body 23 connected to the four-way pipe 21, a filter channel 24 connected to the pump body 23, and a filter box 25 arranged on the filter channel 24.

[0096] Furthermore, one of the interfaces of the four-way pipe 21 is connected to the pump body 23. When the first solenoid valve 22 on the two interfaces connecting the four-way pipe 21 with the pump body 23 and the reaction device 1 is in a connected state, the soaking liquid in the reaction device 1 can be extracted through the pump body 23, thereby realizing the circulation of the soaking liquid. In some embodiments, the pump body 23 can be a magnetic pump, which can use magnetic coupling technology to transmit power, thereby realizing pumping without shaft seals or mechanical seals, effectively avoiding the leakage problem that may occur in traditional pumps when conveying toxic, harmful or corrosive media.

[0097] In some embodiments, the filter box 25 is disposed in the filter channel 24, and is used to filter the soaking liquid passing through the filter channel 24. Furthermore, a first filter screen 251 and a second filter screen 252 are provided in the filter box 25. In some embodiments, the filter mesh diameters of the first filter screen 251 and the second filter screen 252 are different. For example, the filter mesh diameter of the first filter screen 251 may be directly larger than the filter mesh diameter of the second filter screen 252, so that the soaking liquid is filtered multiple times to enhance the filtering effect.

[0098] Further, the circulation device 2 further includes: a first connecting pipe 26 connected to the filter channel 24, a storage chamber 261 connected to the first connecting pipe 26, and a backwash channel 27 connected to the filter box 25. The first connecting pipe 26 is connected to the filter channel 24. In some embodiments, a second solenoid valve 262 is provided on the first connecting pipe 26, and the second solenoid valve 262 is used to adjust the passage state of the first connecting pipe 26. Further, the backwash channel 27 is connected to the filter box 25. When cleaning the filter box 25, the operator can open the second solenoid valve 262 to inject high-pressure water flow or high-pressure air flow into the filter box 25, and backwash the impurities filtered in the filter box 25 into the storage chamber 261, thereby realizing the cleaning process of the filter box 25. Of course, the circulation process of the soaking liquid can also be realized by closing the second solenoid valve 262 and the backwash channel 27. In some embodiments, the storage chamber 261 is a box-type container with a certain volume, which can accommodate multiple impurities and then be processed after cleaning, so as to avoid the operator from having to process multiple times during use, reduce the operator's labor intensity and enhance practicality.

[0099] In some embodiments, the circulation device 2 also includes: a first storage chamber 28 and a second storage chamber 29, wherein the first storage chamber 28 and the second storage chamber 29 are respectively connected to two of the interfaces of the four-way pipe 21. For example, when the first solenoid valve 22 on the interface connecting the four-way pipe 21 with the reaction device 1 and the first storage chamber 28 and / or the second storage chamber 29 is in a connected state, the soaking liquid can be guided to the first storage chamber 28 and / or the second storage chamber 29, and then the soaking liquid is added to the reaction tank 11 to realize the soaking liquid replacement process.

[0100] Furthermore, the injection device 3 is used to add soaking liquid during the soaking liquid circulation process. In some embodiments, the soaking liquid entering the injection device 3 is soaking liquid that has not been soaked. For example, fresh acidic soaking liquid or deionized water can be added to adjust the pH value of the soaking liquid in the circulation process.

[0101] In some embodiments, the injection device 3 includes: a three-way flow guide member 31, a retaining frame 32 arranged in the three-way flow guide member 31, a main shaft 33 movably connected to the retaining frame 32, and a guide fin 34 arranged on the main shaft 33. In some embodiments, the three-way flow guide member 31 is a connecting pipe fitting with three guide ports, wherein the three-way flow guide member 31 includes two groups of flow guide covers 311, and a containing tube 312 connected between the two groups of flow guide covers 311, and the containing tube 312 is arranged perpendicular to the two groups of flow guide covers 311.

[0102] In some embodiments, the flow guide cover 311 is a funnel-shaped structure, so as to guide the soaking liquid into the receiving tube 312, or discharge the soaking liquid from the receiving tube 312. The receiving tube 312 is a hollow structure, and its two sides are respectively connected to the flow guide cover 311. By arranging the retaining frame 32 in the receiving tube 312, the retaining frame 32 divides the hollow structure of the receiving tube 312 into a flow guide chamber 313 and a mixing chamber 314, wherein the flow guide chamber 313 is connected to the flow guide cover 311.

[0103] In some embodiments, the guide fins 34 are disposed on the main shaft 33 and are located in the guide chamber 313 . When the soaking liquid flows through the guide chamber 313 , the main shaft 33 is driven to rotate under the action of the guide fins 34 .

[0104] In some embodiments, the liquid injection device 3 also includes: a liquid injection tank 35, an arc tube 36 connected to the liquid injection tank 35, a sleeve 37 connected to the main shaft 33, an inward rotating piston 38 adapted to the sleeve 37, and a booster blade 39 arranged on the sleeve 37, wherein the inward rotating piston 38 is adapted to the arc tube 36 and is used to adjust the connectivity state of the arc tube 36, and the booster blade 39 is arranged in the liquid injection tank 35.

[0105] In some embodiments, the liquid filling tank 35 is respectively connected to the first replenishing tube 14 and the second replenishing tube 16. When the soaking liquid is replenished into the liquid filling device 3, the soaking liquid first enters the liquid filling tank 35 and then enters the arc tube 36. When the soaking liquid circulates, the inward rotating piston 38 abuts against the end of the arc tube 36 away from the liquid filling tank 35 to block the arc tube 36 to prevent the soaking liquid in the arc tube 36 from entering the mixing tank 314.

[0106] Furthermore, the shaft sleeve 37 is movably connected to the main shaft 33 via a spline. In some embodiments, when the main shaft 33 rotates, the shaft sleeve 37 can be driven to rotate along with the main shaft 33, thereby driving the booster blades 39 to rotate. When the booster blades 39 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 37 to move in the direction close to the inward rotating piston 38, and then pushing the inward rotating piston 38 to move, so that the inward rotating piston 38 is separated from the arc tube 36.

[0107] In some embodiments, a spring 381 is provided at one end of the inwardly rotating piston 38 away from the sleeve 37. When the soaking liquid is in a circulation state, the circulation flow rate of the soaking liquid in the three-way guide member 31 is a first circulation flow rate. Under the limiting action of the spring 381, the inwardly rotating piston 38 is in a state of blocking the arc tube 36; when the soaking liquid is in a circulation replenishment state, the circulation flow rate of the soaking liquid in the three-way guide member 31 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 31 increases, under the action of the guide fins 34, the rotation speed of the main shaft 33 is accelerated, and the thrust generated by the booster blades 39 is greater, thereby compressing the spring 381, so that the inwardly rotating piston 38 is separated from one end of the arc tube 36, so that the soaking liquid in the arc tube 36 can enter the mixing chamber 314.

[0108] In some embodiments, a through hole 321 is provided on the retaining frame 32, so that the mixing chamber 314 and the guide chamber 313 are in a connected state, so that the replenished soaking liquid can enter the three-way guide member 31 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 pH value of the soaking liquid can be adjusted by the replenished soaking liquid.

[0109] In some embodiments, the detection device 4 is used to detect the state information of the soaking liquid. The detection device 4 includes a reflux pipe 41, and a pH meter 42, a flow meter 43 and a temperature sensor 44 arranged on the reflux pipe 41. In some embodiments, the reflux pipe 41 is connected to the injection device 3, and is used to receive the circulating soaking liquid or the circulating soaking liquid after injection; in some embodiments, the pH meter 42 is used to detect the acidity and alkalinity of the soaking liquid. For example, the pH meter 42 can determine the pH value by detecting the concentration of hydrogen ions (H⁺) in the solution; in some embodiments, the flow meter 43 is used to obtain the circulation flow of the soaking liquid. For example, a differential pressure flow meter can measure the flow by detecting the pressure difference generated when the fluid flows through a throttling device (such as an orifice plate, a venturi tube, etc.); in some embodiments, the temperature sensor 44 is used to obtain the temperature of the soaking liquid.

[0110] Furthermore, the reaction device 1 also includes: a ring pipe 17, and a branch pipe 18 connected to the ring pipe 17, wherein the ring pipe 17 is connected to the reflux pipe 41, and is used to receive the circulating soaking liquid or the circulating soaking liquid after injection; the branch pipe 18 is dispersedly connected to the reaction tank 11, and is used to dispersely inject the circulating soaking liquid or the circulating soaking liquid after injection into the reaction tank 11, so that the soaking liquid in the reaction tank 11 is evenly dispersed.

[0111] The soaking liquid pH monitoring system also includes:

[0112] The status judgment module can judge the degree of abnormality of the pH information of the soaking liquid.

[0113] In some embodiments, the state judgment module can establish a database based on industry experience, historical data and other information to determine the degree of abnormality of the pH information of the soaking liquid.

[0114] The abnormality processing module determines a processing plan in response to the abnormal pH value of the soaking liquid.

[0115] In some embodiments, when the pH information of the soaking liquid is abnormal in a mild manner, the corresponding treatment plan determined by the abnormality handling module may be to adjust the flow rate of the soaking liquid circulation. For another example, when the pH information of the soaking liquid is abnormal in a moderate manner, the corresponding treatment plan determined by the abnormality handling module may be to replenish the soaking liquid. For another example, when the pH information of the soaking liquid is abnormal in a severe manner, the corresponding treatment plan determined by the abnormality handling module may be to replace the soaking liquid.

[0116] A second aspect of the present invention provides a method for monitoring pH value of a soaking liquid, based on a system for monitoring pH value of a soaking liquid described in the first embodiment, comprising the following steps:

[0117] S1, obtaining soaking liquid status information;

[0118] In some embodiments, the soaking liquid state information refers to information related to the soaking liquid. In some embodiments, the soaking liquid state information includes acid-base information of the soaking liquid.

[0119] In some embodiments, the soaking liquid state information can be obtained by a pH meter.

[0120] S2. Determine whether the state of the soaking liquid is abnormal based on the soaking liquid state information.

[0121] In some embodiments, the abnormal state of the soaking liquid means that the state information of the soaking liquid exceeds the normal range of the soaking liquid state. In some embodiments, the abnormal state of the soaking liquid may cause abnormal pH of the soaking liquid.

[0122] In some embodiments, determining whether the soaking liquid state is abnormal includes:
