[0002] Tetrapotassium pyrophosphate is a white crystalline powder or granule. It is usually made by melting dipotassium hydrogen phosphate at high temperature and losing water molecules. It is an indispensable raw material in chemical and industrial production. Tetrapotassium pyrophosphate is relatively stable at room temperature and is not easy to decompose.

[0033] 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.

[0034] See also Figure 1-6The present invention provides a technical solution: a conveying and packaging device for tetrapotassium pyrophosphate, comprising a frame 1, on which a loading and detecting component 2, a conveying and diverting component 3, a drying component 4, and a packaging component 5 are respectively arranged.

[0035] As indicated Figure 2 The receiving and testing component 2 includes a discharge box 6, a feed inlet 7 is provided on the upper side of the discharge box 6, and a discharge outlet 8 is provided on the lower side of the discharge box 6;

[0036] As indicated Figure 2 , indicating Figure 3 A flattening assembly 9 is arranged above the feed port 7, and the flattening assembly 9 includes a pressing plate 10. Two connecting rods 11 are arranged on the upper side of the pressing plate 10, which are symmetrical to each other with the center line of the pressing plate 10 as the reference. A connecting block 12 is fixedly connected to the side of the two connecting rods 11 away from the pressing plate 10. A hydraulic telescopic cylinder 13 is arranged on the lower side of the connecting block 12 away from the connecting rod 11. The fixed end of the hydraulic telescopic cylinder 13 is fixedly connected to the frame 1, and the output end of the hydraulic telescopic cylinder 13 is fixedly connected to the connecting block 12;

[0037] The cross-sectional shape of the pressing plate 10 along the horizontal plane is consistent with the cross-sectional shape of the inner cavity of the feed port 7 along the horizontal plane. The pressing plate 10 cooperates with the feed port 7. After the material is discharged into the discharge box 6, the pressing plate 10 moves downward into the feed port 7 under the action of the hydraulic telescopic cylinder 13 to flatten the upper surface of the material in the discharge box 6.

[0038] A pressure sensor (not shown in the figure) is embedded on the lower side of the pressing plate 10. The contact end of the pressure sensor is flush with the bottom surface of the pressing plate 10 and is used to detect the pressure of the pressing plate 10 on the material. When the pressure sensor detects that the pressure value of the pressing plate 10 is constant at Y1, the downward pressure is stopped. Under this pressure state, the pressing plate 10 flattens the upper surface of the material in the discharge box 6 without causing excessive squeezing of the material.

[0039] An opening and closing component 14 is provided at the discharge port 8 of the discharge box 6. The opening and closing component 14 is used to control the opening and closing of the discharge port 8. The opening and closing component 14 includes a baffle 15. The baffle 15 penetrates the upper cavity wall of the discharge port 8 and is slidably connected to the cavity wall of the discharge port 8. Two groups of hydraulic telescopic cylinders 2 16 are provided on the side of the baffle 15 away from the discharge port 8. The fixed ends of the two groups of hydraulic telescopic cylinders 2 16 are fixedly connected to the outer wall of the discharge box 6, and the output ends of the two groups of hydraulic telescopic cylinders 2 16 are fixedly connected to the baffle 15.

[0040] Infrared emitting gratings 17 and infrared receiving gratings 18 are respectively embedded in the inner walls of the upper cavity of the discharge box 6 on both sides opposite to each other. The infrared emitting gratings 17 and the infrared receiving gratings 18 are vertically arranged and opposite to each other. The emitting end of the infrared emitting grating 17 and the receiving end of the infrared receiving grating 18 are flush with the inner wall of the upper cavity of the discharge box 6 to prevent the pressing plate 10 from damaging the infrared emitting grating 17 and the infrared receiving grating 18 during the pressing process. The infrared emitting grating 17 and the infrared receiving grating 18 form a group of infrared counter-radiation gratings, which are conventional technologies.

[0041] The infrared counter-radiation grating signal is connected to a processor (not shown in the figure), and the processor measures the volume of the flattened material in the discharge box 6 through the infrared counter-radiation grating. Specifically, the infrared emission grating 17 emits a laser, which is received by the infrared receiving grating 18. Under the obstruction of the material in the discharge box 6, part of the length of the laser emitted by the infrared emission grating 17 is blocked by the material in the discharge box 6 and cannot be received by the infrared receiving grating 18. Only the part on the upper side where there is no material can be successfully received by the infrared receiving grating 18. The length of infrared rays received by the infrared receiving grating 18 is negatively correlated with the volume of the material contained in the discharge box 6, that is, the shorter the length of infrared rays received by the infrared receiving grating 18, the larger the volume of the material contained in the discharge box 6. The infrared receiving grating 18 inputs the received infrared length signal into the processor, and the processor calculates the overall volume of the material in the discharge box 6.

[0042] Two groups of upper and lower parallel limit plates 19 are horizontally arranged on the frame 1, the discharge box 6 passes through the two groups of limit plates 19 and is slidably connected with the limit plates 19 up and down, and the outer wall of the discharge box 6 located between the two groups of limit plates 19 is fixedly connected with a connecting plate 20, the connecting plate 20 is horizontally arranged, and a group of gravity sensors 21 are arranged at the four corners of the lower side of the connecting plate 20. The signal of the gravity sensor 21 is connected to the processor, and the fixed end of the gravity sensor 21 is fixedly connected to the upper side of the lower group of limit plates 19, and the receiving end of the gravity sensor 21 is fixedly connected to the connecting plate 20. When the discharge box 6 is loaded with materials, the weight of the materials in the discharge box 6 is measured by the gravity sensor 21.

[0043] The density P1 of the unit volume of the material in a dry state is set in the processor, and the actual volume V1 of the material in the discharge box 6 is calculated by the data transmitted by the infrared grating. Combined with P1, the theoretical weight G1 of the material in the discharge box 6 in a dry state is calculated, G1=P1*V1, and compared with the actual weight G2 of the material in the discharge box 6 calculated by the data transmitted by the gravity sensor 21, the ratio M1 of the moisture content in the material when the volume is V1 is calculated, M1=(G2-G1) / V1*100%, and the value of M1 under the limit state is not more than 60%;

[0044] The moisture content of the material in the discharge box 6 is calculated in this way, so that in the subsequent process, different degrees of drying treatment can be carried out according to the moisture content of the material.

[0045] As indicated Figure 4 The conveying and diversion component 3 is located below the loading and detection component 2. The conveying and diversion component 3 includes a conveyor belt 22. The belt edges of the conveyor belt 22 at both ends along the width direction are connected with shielding belts 23. The conveyor belt 22 is an existing conventional technology. The width of the conveyor belt 22 is adapted to the length of the discharge port 8 of the discharge box 6, so that the discharge port 8 is fully laid on the surface of the conveyor belt 22 along the width direction of the belt surface of the conveyor belt 22 when discharging materials. The shielding belt 23 is used to prevent the material on the belt surface of the conveyor belt 22 from spilling out of the conveyor belt 22.

[0046] The operation of the conveyor belt 22 causes the conveyor belt 22 to move toward the side away from the discharge box 6. A material leveling assembly 24 is provided on one side of the output end of the conveyor belt 22. The material leveling assembly 24 includes a roller 25. The roller 25 is located above the belt surface of the conveyor belt 22. The roller surface length of the roller 25 is the same as the width of the belt surface of the conveyor belt 22. The bearings at both ends of the roller 25 along the axial direction are connected with brackets 26. One end of the driving shaft of the roller 25 passes through the bracket 26 and is fixedly connected to a driving motor 27. A hydraulic telescopic cylinder 3 28 is provided below the side of the bracket 26 away from the roller 25. The fixed end of the hydraulic telescopic cylinder 3 28 is fixedly connected to the frame 1, and the output end of the hydraulic telescopic cylinder 3 28 is fixedly connected to the bracket 26. The material on the conveyor belt 22 is rolled evenly by rotating the roller 25. At the same time, the distance between the roller 25 and the belt surface of the conveyor belt 22 is controlled by the telescopic movement of the hydraulic telescopic cylinder 3 28, so as to control the thickness of the rolled material.

[0047] A leveling plate 29 is provided on one side of the roller 25 close to the output end of the conveyor belt 22. Both sides of the leveling plate 29 in the length direction are fixedly connected to the bracket 26. The leveling plate 29 is inclined toward one side of the output end of the conveyor belt 22. The horizontal height of the bottom side of the downwardly inclined end of the leveling plate 29 is consistent with the horizontal height of the lowest end of the roller surface of the roller 25. The leveling plate 29 is used for secondary leveling of the material after being rolled by the roller 25.

[0048] A plurality of groups of diverter plates 31 are inserted on one side of the leveling plate 29 close to the output end of the conveyor belt 22. The diverter plates 31 are slidably connected to the leveling plate 29. The diverter plates 31 are vertically arranged. Specifically, there are two diverter plates 31. The two diverter plates 31 are evenly distributed along the width direction of the belt surface of the conveyor belt 22, so as to divide the material on the belt surface of the conveyor belt 22 into three equal parts. The diverter plate 31 is provided with a groove 32 toward one side of the conveyor belt 22. The groove 32 matches the cross-sectional shape of the output end of the conveyor belt 22 along the length direction, so as to improve the diverter effect of the diverter plate 31.

[0049] A collecting groove 33 is provided at the lower side of the diverter plate 31. The collecting groove 33 is open to the upper side. The upper end surface of the collecting groove 33 close to the conveyor belt 22 is in direct contact with the lower side of the conveyor belt 22 to scrape off the materials attached to the conveyor belt 22.

[0050] The lower part of the diverter plate 31 is fixedly connected to the collecting tank 33, and the collecting tank 33 is partitioned to form three diverter tanks 34. The diverter tanks 34 are funnel-shaped, and the lower sides of the three diverter tanks 34 are all provided with flow outlets 35, which are connected to the drying component 4 through pipelines.

[0051] As indicated Figure 5 The drying component 4 includes three tubes 36, each tube 36 corresponds to a diverter slot 34, and the three tubes 36 are arranged horizontally and in parallel. A second feed port 37 is provided on one side of the three tubes 36 close to the diverter slot 34, and the second feed port 37 is connected to the outlet 35 of the diverter slot 34 through a pipeline;

[0052] The three tube bodies 36 are provided with a lumen 1 38, a spiral rod 39 concentric with the lumen 1 38 is provided in the lumen 1 38, a spiral leaf 40 is fixedly connected to the spiral rod 39, the side of the spiral leaf 40 away from the spiral rod 39 is in direct contact with the inner wall of the lumen 1 38, and the side of the spiral rod 39 close to the conveyor belt 22 penetrates the inner wall of the lumen 1 38 and is fixedly connected to a drive motor 2 41, which is fixedly connected to the frame 1, and drives the spiral leaf 40 to rotate through the spiral rod 39 to transport the material entering the lumen of the tube body 36;

[0053] The tube cavity 38 is formed with a heating section and a cooling section along the axial direction. The heating section is close to the conveyor belt 22. The outer wall of the tube body 36 on the heating section is sleeved with a heater 42. The heater 42 is conventional technology. The heating end of the tube cavity 38 is heated by the heater 42 to evaporate the water contained in the material to form water vapor.

[0054] The outer wall of the tube body 36 is provided with an air duct 43 on the heating section. The tube body 36 is provided with an air outlet 44 at a position corresponding to the air duct 43. The tube cavity of the tube body 36 is connected to the air duct 43 through the air outlet 44. The output end of the air duct 43 is connected to a fan 45. The fan 45 sucks the water vapor evaporated from the tube cavity 38 in the heating section through the air duct 43.

[0055] An air inlet 46 is provided on the outer wall of the tube body 36 in the heating section, and a filter is fixedly connected to the air inlet 46 to prevent dust from entering the tube body 36. When the fan 45 sucks water vapor in the tube cavity of the tube body 36, dry air is introduced into the tube cavity of the tube body 36 through the air inlet 46 to balance the air pressure in the tube cavity of the tube body 36.

[0056] The outer wall of the tube body 36 in the cooling section is sleeved with a refrigerator 47, which is conventional technology. The refrigerator 47 cools the tube cavity of the tube body 36 in the cooling section to cool the material after drying to prevent overheating of the material and affect subsequent discharging and packaging.

[0057] As indicated Figure 6 The tube body 36 is provided with a second discharge port 48 on one side away from the conveyor belt 22. The second discharge port 48 is connected to the sub-packaging assembly 5 through a pipeline. The sub-packaging assembly 5 includes three square tubes 49. The three square tubes 49 are vertically arranged. Each square tube 49 corresponds to a tube body 36. The upper pipe opening of the square tube 49 is connected to the second discharge port 48 of the tube body 36 through a pipeline.

[0058] A set of opening and closing components 2 50 are arranged near the upper and lower pipe openings on the square tube 49, and the opening and closing components 2 50 include baffle 2 51, which penetrates the pipe wall of one side of the square tube 49 and is slidably connected to the square tube 49, and the baffle 2 51 seals the pipe cavity of the square tube 49. A hydraulic telescopic cylinder 4 30 is arranged on the side of the baffle 2 51 away from the square tube 49, and the fixed end of the hydraulic telescopic cylinder 4 30 is fixedly connected to the frame 1, and the output end of the hydraulic telescopic cylinder 4 30 is fixedly connected to the baffle 2 51;

[0059] The portion of the square tube 49 located between the upper and lower opening and closing components forms a storage cavity for storing the material transported by the drying component 4 after drying.

[0060] Two upper and lower parallel limit plates 52 are arranged on the frame 1, and three square tubes 49 are all penetrated through the two limit plates 52 and connected with the limit plates 52 for upward and downward sliding. The parts of the three square tubes 49 located between the two limit plates 52 are all fixedly connected with a connecting plate 53, and the connecting plate 53 is arranged horizontally. A group of gravity sensors 54 are arranged at the four corners of the lower side of the connecting plate 53, and the signal of the gravity sensor 54 is connected to the processor. The fixed end of the gravity sensor 54 is fixedly connected to the upper side of a group of limit plates 52 on the lower side, and the receiving end of the gravity sensor 54 is fixedly connected to the connecting plate 53;

[0061] In the initial state, the baffle plate 2 51 of the lower group of opening and closing components blocks the tube cavity of the square tube 49. After the material is dried and transported by the drying component 4, it enters the square tube 49 and is stored in the storage cavity of the square tube 49. The gravity sensor 2 54 is set by the processor. When it detects that the weight of the square tube 49 and the material stored in the square tube 49 reaches G3, the baffle plate 2 51 of the upper group of opening and closing components blocks the tube cavity of the square tube 49, and the baffle plate 2 51 of the lower group of opening and closing components moves out of the tube cavity of the square tube 49. The material stored in the storage cavity flows out from the lower side of the square tube 49. After the material flows out of the storage cavity, the baffle plate 2 51 of the lower group of opening and closing components 50 is again blocked to block the tube cavity of the square tube 49. At the same time, the baffle plate 2 51 on the upper group of opening and closing components 50 is controlled to move out of the tube cavity of the square tube 49, and the material on the baffle plate 2 51 in the upper group of opening and closing components 50 falls into the storage cavity.

[0062] The tube cavity portion on the upper side of the second opening and closing component 50 on the square tube 49 allows the material in the storage cavity to be contained by the drying component 4 when the material completely flows out of the square tube 49, thereby preventing the material from overflowing.

[0063] Three groups of balers (not shown in the figure) are arranged below the subpackaging assembly 5. The balers are conventional technologies. Each group of balers opens the opening of the packing bag for holding materials toward the lower pipe opening of the square tube 49, so that the materials falling from the square tube 49 enter the packing bag.

[0064] Therefore, the capacity of the storage chamber in the square tube 49 is greater than the capacity of the packing bag. Every time the gravity sensor 2 54 detects that the weight of the square tube 49 and the material in the square tube 49 reaches G3, it means that the volume of the material in the storage chamber in the square tube 49 is consistent with the capacity of the packing bag. A set of opening and closing components 2 50 on the upper and lower sides of the square tube 49 can be opened to allow the material in the storage chamber to fall into the packing bag, thereby completing the packaging and packing of the material.

[0065] In this embodiment, the material is poured into the discharge box 6. At this time, the baffle 15 of the opening and closing component 14 blocks the discharge port 8 of the discharge box 6. After the material is poured, the output end of the hydraulic telescopic cylinder 13 is controlled to retract, so that the pressing plate 10 descends and enters the feed port 7. The pressure of the pressing plate 10 is monitored in real time by the pressure sensor. When the pressure of the pressing plate 10 is constant at Y1, it means that the upper surface of the material is flattened and the material in the discharge box 6 is not over-extruded. Since the material is a granular structure, the density of the material in the discharge box 6 will not change.

[0066] Subsequently, the infrared grating irradiates the material in the discharge box 6, and the processor calculates the volume of the material in the discharge box 6 by the length of the infrared rays received by the infrared receiving grating 18, and calculates the actual volume of the material in the discharge box 6 as V1;

[0067] The density P1 of the unit volume of the material in a dry state is set in the processor, and the theoretical weight G1 of the material in the discharge box 6 in a dry state is calculated in combination with P1, G1=P1*V1, and compared with the actual weight G2 of the material in the discharge box 6 calculated from the data transmitted by the gravity sensor 21, so as to calculate the ratio M1 of the moisture content in the material when the volume of the material is V1, M1=(G2-G1) / V1*100%, and the value of M1 under the limit state is not more than 60%.

[0068] Processors are classified according to the value of M1, as follows:

[0069] Grade A1: M1≤20%, indicating that the material contains less moisture;

[0070] Grade A2: 20%<M1<40%, indicating that the moisture content of the material is high;

[0071] Grade A3: 40≤M1≤60%, indicating that the material contains extremely high moisture content.

[0072] The baffle plate 15 of the opening and closing component 14 is controlled to move out of the discharge port 8, and the material in the discharge box 6 falls on the conveyor belt 22 under the action of gravity, and moves from the belt body of the conveyor belt 22 to the side of the material leveling component 24;

[0073] The hydraulic telescopic cylinder 430 controls the distance between the roller 25 and the surface of the conveyor belt 22 corresponding to the level of M1, and has three different heights of movement, specifically H1, H2, and H3, H1<H2<H3, and the distance between the roller 25 and the surface of the conveyor belt 22 is negatively correlated with the level of M1;

[0074] When M1 is at level A1, the height of the roller 25 from the conveyor belt 22 is controlled to be H3, indicating that the moisture content of the material is low, and the thickness of the material rolled evenly by the roller 25 on the conveyor belt 22 needs to be increased to improve the subsequent drying and conveying efficiency;

[0075] When M1 is at level A2, the height of the roller 25 from the conveyor belt 22 is controlled to be H2, indicating that the moisture content of the material is high, and the rolling thickness of the material on the conveyor belt 22 by the roller 25 needs to be reduced, so as to improve the subsequent drying and conveying efficiency;

[0076] When M1 is at level A3, the height of the roller 25 from the conveyor belt 22 is controlled to be H1, indicating that the moisture content of the material is extremely biased, and the thickness of the material rolled on the conveyor belt 22 by the roller 25 needs to be minimized to improve the subsequent drying and conveying efficiency;

[0077] The material leveled on the conveyor belt 22 falls into the diversion groove 34 under the diversion effect of the diversion plate 31, and enters the tube cavity 38 of the drying component 4. In the tube cavity 38, the driving motor 27 is started to drive the spiral blade 40 to rotate, and the spiral blade 40 pushes the material in the tube cavity 38 to move at a uniform speed to the side of the discharge port 48, and is heated by the heater 42 in the heating section, so that the water contained in the material evaporates and is sucked out by the fan 45;

[0078] The heater 42 generates three groups of heating levels with different heating powers corresponding to the level control of M1, specifically R1, R2, and R3, R1<R2<R3, and the distance between the roller 25 and the belt surface of the conveyor belt 22 is positively correlated with the level of M1;

[0079] When M1 is at level A1, the heating level of the heater 42 is controlled to be R1, indicating that the moisture content of the material is low and the material only needs to be dried with the lowest heating power;

[0080] When M1 is at level A2, the heating level of the heater 42 is controlled to be R2, indicating that the moisture content of the material is high and the material needs to be dried with a medium heating power;

[0081] When M1 is at level A3, the heating level of the heater 42 is controlled to be R3, indicating that the moisture content of the material is extremely high and the material needs to be dried with the maximum heating power;

[0082] After drying, the material is pushed by the spiral blade 40 into the cooling section of the tube cavity 38 for cooling, so as to prevent the temperature of the material from being too high when the material is subsequently packaged.

[0083] After cooling, the material is transported out from the discharge port 248 of the tube body 36 and falls into the square tube 49 of the packaging component 5. In the initial state, the baffle 251 of the lower group of opening and closing components blocks the tube cavity of the square tube 49. After the material is dried and transported out by the drying component 4, it enters the square tube 49 and is stored in the storage cavity of the square tube 49. The gravity sensor 254 is set by the processor. When it detects that the weight of the square tube 49 and the material stored in the square tube 49 reaches G3, the baffle 251 of the upper group of opening and closing components blocks the tube cavity of the square tube 49, and the baffle 251 of the lower group of opening and closing components moves out of the tube cavity of the square tube 49. The material stored in the storage cavity flows out from the lower side of the square tube 49 into the opened packaging bag on the packaging machine, and is packaged by the packaging machine.

[0084] After the material flows out of the storage cavity, the baffle 2 51 of the lower group of opening and closing components 2 50 is again used to block the cavity of the square tube 49. At the same time, the baffle 2 51 on the upper group of opening and closing components 2 50 is controlled to move out of the cavity of the square tube 49. The material on the baffle 2 51 in the upper group of opening and closing components 2 50 falls into the storage cavity for the next packaging work.
