DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments 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.

[0028] Example 1: Please refer to Figure 1-5 The present invention provides a technical solution: an intelligent storage device for sodium pyrophosphate, comprising a storage cabinet 1, a material taking mechanism and a management system, wherein the storage cabinet 1 comprises a plurality of unit cabinets 11 and a bracket 12, wherein the unit cabinets 11 are arranged on the bracket 12, the unit cabinet 11 comprises a side panel 13 and a bottom panel 14, one side of the unit cabinet 11 is open, and a vertically through space is reserved between the side panel 13 and the bottom panel 14, the upper side of the bottom panel 14 is a stacking place for sodium pyrophosphate packaging bags, and a gravity sensing module is arranged on the upper surface of the bottom panel 14 for monitoring the quality change of sodium pyrophosphate during storage, the material taking mechanism is arranged on the opening side of the unit cabinet 11, and is used to take out the sodium pyrophosphate packaging bags in the unit cabinet 11, and the management system is connected with the storage cabinet 1 and the material taking mechanism by signal, and is used to monitor the state of the stored sodium pyrophosphate packaging bags and perform corresponding processing according to the abnormal state;

[0029] An exhaust pipe 2 and an air supply pipe 3 are provided on the top of the storage cabinet 1, and a plurality of branch pipes 4 are respectively connected to the exhaust pipe 2 and the air supply pipe 3. The branch pipes 4 are inserted into the space reserved between the side plate 13 and the bottom plate 14 and a switch valve 5 is provided toward the inner side of each unit cabinet 11. The air supply pipe 3 is connected to a dehumidification box 31, and the exhaust pipe 2 is connected to a cooling box 21. A through pipe 6 is connected between the dehumidification box 31 and the cooling box 21.

[0030] Supplementary explanation based on the above structure is as follows: the gravity sensing module is composed of several sensing units (g1, g2, g3...gn). In the initial state, no external force is applied to the upper side of the bottom plate 14, and each sensing unit gn=0. When the sodium pyrophosphate packaging bag is moved to the bottom plate 14, the values ​​detected by the corresponding sensing units increase to varying degrees and eventually tend to a stable value.

[0031] An air pump 1 32 is provided between the air supply pipe 3 and the dehumidification box 31 , and an air pump 2 22 is provided between the air extraction pipe 2 and the cooling box 21 .

[0032] Preferably, the dehumidification method adopted by the dehumidification box 31 is not unique, and the cooling method adopted by the cooling box 21 is not unique. In one embodiment, a partition plate 311 is provided in the dehumidification box 31, and one side of the partition plate 311 is filled with a water-absorbing material 312. The partition plate 311 is a grid structure for gas circulation, and the other side of the partition plate 311 is a humidity detection chamber 313. The humidity detection chamber 313 is provided with a humidity sensor for detecting the humidity of the gas after dehumidification. Passages 314 are connected to both sides of the partition plate 311, and an air pump 315 is provided on the passage 314 for secondary dehumidification when the gas humidity value is not ideal; a temperature sensor is provided in the cooling box 21 for detecting the internal gas temperature, and the cooling box 21 is externally connected to a refrigeration system for inputting a temperature-adjustable low-temperature airflow into the cooling box 21 to cool it by mixing with the original gas. Furthermore, by pressurizing the cooling box 21, it can assist in cooling and removing moisture from the gas.

[0033] In actual operation, the management system can realize the temperature and humidity adjustment of the storage cabinet 1. By setting the temperature and humidity range required for the storage of sodium pyrophosphate packaging, the exhaust pipe 2 is controlled to extract the gas in each unit cabinet 11, and then the original gas is extracted, and it is re-delivered to each unit cabinet 11 after cooling and dehumidification, so that each unit cabinet 11 can maintain a temperature and humidity range suitable for storage while maintaining gas circulation.

[0034] The material picking mechanism comprises a transverse axis driving module 7 , a longitudinal axis driving module 8 and a material picking assembly, wherein the longitudinal axis driving module 8 is installed at the driving end of the transverse axis driving module 7 , and the material picking assembly is installed at the driving end of the longitudinal axis driving module 8 .

[0035] In one embodiment, the transverse axis driving module 7 and the longitudinal axis driving module 8 are preferably, but not limited to, driven by screws to control the material taking components to match the corresponding unit cabinets 11 .

[0036] The material picking assembly includes several auxiliary modules 91 and a material lifting module 92, wherein the auxiliary module 91 includes a lifting frame 911, which is a U-shaped structure and is attached to the surface of the bottom plate 14. Both ends of the lifting frame 911 are connected with rotating shafts 912, one end of the rotating shaft 912 is rotatably matched with the bottom plate 14 and a torsion spring is provided at the connection, and the rotating shaft 912 is fixed with a pressure plate 913, and the initial height of the pressure plate 913 is higher than the plane where the bottom plate 14 is located.

[0037] In actual operation, when the pressure plate 913 is pressed down by external force, the rotating shaft 912 is driven to rotate, and the rotating shaft 912 drives the lifting frame 911 to deflect and lift the sodium pyrophosphate packaging bag, thereby assisting the lifting module 92 to take the material. When the external force leaves the pressure plate 913, the rotating shaft 912 is reset by the tension of the torsion spring.

[0038] The material lifting module 92 includes a cylinder 1 921, a fixed plate 922, a lifting plate 923, a cylinder 2 924, a connecting plate 925 and a cylinder 3 926, wherein the fixed plate 922 is connected to the driving end of the cylinder 1 921, the cylinder 2 924 is fixed on the lifting plate 923 and the movable end is connected to the fixed plate 922, one side of the connecting plate 925 is hinged to the lifting plate 923, the fixed end of the cylinder 3 926 is connected to the lifting plate 923, and the movable end of the cylinder 3 926 is hinged to the connecting plate 925.

[0039] In actual operation, the telescopic movement of cylinder three 926 is used to control the lifting and lowering of the connecting plate 925, the telescopic movement of cylinder two 924 is used to adjust the height of the lifting plate 923, and cylinder one 921 is used to adjust the distance between the fixed plate 922 and each unit cabinet 11.

[0040] The management system includes a data acquisition module, an information analysis module and a processing module, wherein the data acquisition module includes a gravity acquisition unit, a temperature acquisition unit and a humidity acquisition unit, and the information analysis module includes an external cause analysis unit and an internal cause analysis unit.

[0041] Specifically, the management method of the management system is as follows:

[0042] Step 1: transport the sodium pyrophosphate packaging bag to the unit cabinet 11 for storage;

[0043] Step 2: The management system controls the air pump 1 32 and the air pump 2 22 to perform ventilation according to the set temperature and humidity range, the data acquisition module collects the temperature and humidity data of the extracted gas, and the processing module adjusts the temperature and humidity of the input gas according to the value, so that the temperature and humidity in each unit cabinet 11 are within the optimal storage range of sodium pyrophosphate;

[0044] Step 3: The data acquisition module collects the gravity values ​​detected by each sensing unit after the sodium pyrophosphate packaging bag is placed, monitors the value changes during storage, the information analysis module analyzes the reasons based on the value changes, and the processing module performs corresponding processing based on the analysis structure.

[0045] Specifically, in step 2, if the temperature acquisition unit acquires an abnormal temperature signal, the unit cabinet 11 with abnormal temperature can be locked by controlling the switch state of each switch valve 5. Preferably, the column where the abnormal unit cabinet 11 is located is checked by column as a unit, and the switch valve 5 corresponding to the branch 4 of the first column unit cabinet 11 is opened, and the other switch valves 5 are all in a closed state. The exhaust pipe 2 extracts the gas in the first column unit cabinet 11 to determine whether this column of unit cabinets 11 has an abnormality. If not, continue to detect other columns of unit cabinets 11. If so, on the premise that the switch valves 5 of other columns of unit cabinets 11 are in a closed state, open the switch valve 5 of each row of unit cabinets 11 in the first column one by one to lock the abnormal unit cabinet 11. In order to avoid abnormal situations in multiple unit cabinets 11, even if the front column unit cabinet 11 has an abnormality, it is still necessary to check the rear column unit cabinet 11. During the checking process, the air supply pipe 3 is closed by default to avoid affecting the checking results.

[0046] Furthermore, when an abnormal temperature signal appears and the abnormal unit cabinet 11 is locked, the processing module first closes the switch valve 5 of other unit cabinets 11, lowers the temperature of the input gas, and detects whether the temperature of the recovered gas returns to the normal temperature range. If the detected temperature is still higher than the set value, while maintaining the input low-temperature gas state, notify the operator to conduct an investigation.

[0047] In step three, when each sensing unit detects a local increase in gravity value, the information analysis module determines that it is caused by internal factors, that is, the sodium pyrophosphate inside the packaging bag absorbs water and causes the mass to increase. At this time, the processing module controls the material taking mechanism to move to the corresponding unit cabinet 11 to take materials. During the material taking process, if the local sensing unit can still detect a gravity signal that is significantly greater than the initial value, it is determined that the packaging bag is damaged and the internal sodium pyrophosphate is leaking. If the sensing unit does not detect an abnormal gravity signal, it means that the packaging bag is intact, but there is a problem with the sealing.

[0048] Furthermore, if each sensing unit detects a constantly changing gravity signal, the information analysis module determines that it is caused by external factors, that is, there is a living thing running in the unit cabinet 11. The processing module controls the cooling box 21 to input extremely low temperature airflow, suppressing the spontaneous movement and exploratory behavior of the organism through cold stimulation, and at the same time monitors the changes in gravity values. After it becomes stable, it notifies the operator to conduct an investigation.

[0049] Embodiment 2: as Figures 6 to 9On the basis of Example 1, in order to ensure the smooth recycling of sodium pyrophosphate packaging bags, a second pressing plate 93 is added to the lifting plate 923, and plug plates 931 are connected to both sides of the second pressing plate 93. A slot 9251 is provided on the connecting plate 925 corresponding to the plug plates 931. A pressure sensing unit is laid on the surface of the second pressing plate 93, and a hole 932 is provided on the surface of the second pressing plate 93. A needle tube 94 is rotatably arranged in the hole 932. The needle tube 94 is a hollow structure. The needle tube 94 includes a needle head 941 and a tube body 942, wherein the needle head 941 faces the pressing surface of the second pressing plate 93, and the tube body 942 extends out of the other side of the second pressing plate 93 and is externally connected to a gas collection box. A driving gear 95 and a driving gear 96 are rotatably arranged on one side of the second pressing plate 93. The driving gear 95 is threadedly matched with the needle tube 94, and the driving gear 95 is rotatably matched with the driving gear 96. The driving gear 96 is connected to a micro motor 97.

[0050] In actual operation, the initial height of the needle 941 should be lower than the plane where the second pressing plate 93 is located. When there is a need to take materials, after the connecting plate 925 receives the sodium pyrophosphate packaging bag, the cylinder three 926 contracts and pulls up the connecting plate 925, so that the plug plate 931 is inserted into the slot 9251, and the sodium pyrophosphate packaging bag is clamped between the connecting plate 925 and the second pressing plate 93. According to the clamping angle between the connecting plate 925 and the second pressing plate 93, the pressure sensing unit detects the pressure from the sodium pyrophosphate packaging bag, thereby judging the expansion degree of the sodium pyrophosphate packaging bag. If the expansion degree of the sodium pyrophosphate packaging bag is small, the corresponding clamping angle when the pressure signal is detected is also small. In order to avoid the clamping process , the sodium pyrophosphate packaging bag falls toward the second pressure plate 93 first. After detecting the first pressure signal, the clamping angle will continue to be reduced until the pressure signal begins to increase steadily. The clamping angle corresponding to the change node shall prevail. If the expansion degree of the sodium pyrophosphate packaging bag exceeds the allowable range and there is a possibility of bag explosion at any time, the needle 941 is inserted into the sodium pyrophosphate packaging bag to guide out excess gas and reduce the internal pressure, thereby avoiding bag explosion. Specifically, the micro motor 97 drives the active gear 96, which indirectly drives the drive gear 95 to rotate, and the tube body 942 rotates forward to extend the needle 941 out of the second pressure plate 93 plane and insert it into the sodium pyrophosphate packaging bag.
