Description

Technical Field

[0001] This invention relates to the field of flash dryers, and is entitled "A flash dryer with multiple self-testing functions and its working method". Background Technology

[0002] Flash dryers are a new type of continuous drying equipment that integrates drying, crushing, and screening. They are particularly suitable for drying filter cake, paste, and slurry-like materials. The system consists of a heater, feeder, mixing and crushing system, classifier, main drying pipe, cyclone separator, bag filter, and fan. It is suitable for paste, slurry, filter cake, and materials dewatered by plate and frame filter presses or centrifuges. Hot air enters tangentially at the bottom of the dryer, forming a powerful rotating airflow under the action of the agitator. Pasty materials enter the dryer through a screw feeder, and under the strong action of the high-speed rotating agitator, the material is dispersed by impact, friction, and shear stress. Lumpy materials are rapidly crushed, fully contacting the hot air, and dried. After dehydration, the dry material rises with the hot airflow. The grading ring retains large particles, while small particles are discharged from the center of the ring and recovered by the cyclone separator and dust collector. Incompletely dried or large pieces of material are thrown against the wall of the dryer by centrifugal force and fall back to the bottom to be crushed and dried.

[0003] However, existing flash dryers require different hot air temperatures when flashing different raw materials. They also need to check whether the hot air temperature meets the standard and whether the discharge port is blocked. Furthermore, the bottom motor requires frequent lubrication and maintenance, and the quality of the flashed raw materials needs to be monitored in real time. Failure to set the correct temperature will affect the flashing efficiency, failure to detect blockages will affect the flashing quantity, and substandard flashed raw materials will require re-flashing, wasting time.

[0004] Therefore, it is necessary to provide a flash dryer with multiple self-inspection functions and its working method, which can achieve the function of self-inspection. Summary of the Invention

[0027] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0028] Please see Figure 1-6 The present invention provides a technical solution: a flash dryer with multiple self-testing functions and its working method, comprising a base 1, a flash cylinder 52, a temperature detection component, a discharge detection component, an oiling component, and a flash effect detection component. The temperature detection component includes a blower 3, a heater 4 is provided at the air outlet end of the blower 3, a detection chamber 6 is provided at the front side of the heater 4, a first detector 12 is provided inside the detection chamber 6, and a sponge 68 is provided inside the first detector 12.

[0029] The discharge detection assembly includes a discharge bin 41, a first cylinder 39, and a detection plate 43. The rod end of the first cylinder 39 is connected to the discharge bin 41. A pusher 42 is provided on the left side of the discharge bin 41, and a feeder 36 is provided on the top of the discharge bin 41.

[0030] The oiling assembly includes a push rod 45, a rotating wheel 47, and a buckle 49. The buckle 49 is engaged with the rotating wheel 47. The top of the push rod 45 is connected to a spring bearing with a paddle 46. The front end of the paddle 46 is engaged with the rotating wheel 47. An oil supply pipe 50 is provided on the front side of the rotating wheel 47.

[0031] The flash evaporation effect detection component includes a filter 55, a turbine 56, and a second detector 64. The filter 55 and the turbine 56 are connected to each other. A connecting rod 57 is provided on the right side of the turbine 56. The connecting rod 57 is used to drive the second detector 64 to start. The blower 3 draws in air, which is turned into hot air by the heater 4 and blown into the flash evaporation cylinder 52. In order to detect whether the hot air after passing through the heater 4 has reached the specified temperature, water is injected into the sponge 68, and the hot air is directed to the wet sponge 68 to heat and evaporate the water inside. The first detector 12 detects the change in the weight of the sponge 68 within a specified time to determine whether the hot air temperature has reached the standard. At the same time as detecting the hot air temperature, the discharge hopper 41 is pressed down, and the feeder 36 injects water into it. As raw materials are fed in, the weight of the discharge bin 41 gradually increases. When the specified time is reached, the internal weight is judged by whether the discharge bin 41 is bounced back to its original position by the first cylinder 39 at the bottom. This indirectly indicates whether the feeder 36 is blocked. The push rod 45 is pushed to make the rotating wheel 47 rotate. After the rotating wheel 47 rotates to a certain angle, the lubricating oil tank on the side will squeeze out a lubricating oil. The oil is transported to the output end of the motor 51 for maintenance through the oil pipe 50. When the flash evaporation effect is poor, the output particles are larger and will block the filter screen 55, thus affecting the air volume. At this time, the rotation speed of the turbine 56 that can be blown by the wind will decrease. The rotation frequency is transmitted to the second detector 64 through the adapter rod 57 to judge whether the flash evaporation effect meets the standard.

[0032] A first support frame 2 is fixedly installed on the top of the base 1. The top of the first support frame 2 is connected to the bottom of the blower 3. The right side of the heater 4 is connected to the flash cylinder 52 through a pipe. A one-way air outlet pipe 5 is provided at the front end of the heater 4, and the one-way air outlet pipe 5 is connected to the detection chamber 6. A second support frame 7 is provided on the top of the base 1. A controller 8 is provided on the front side of the second support frame 7. A buffer 9 is provided above the controller 8. A first spring 10 is wrapped around the outside of the buffer 9. A rotator 11 is provided at the top of the buffer 9. The right side of the rotator 11 is connected to the first detector 12 by a bearing. A first sprocket 13 is provided on the left side of the rotator 11 and is connected to the rotation shaft of the first detector 12. A second sprocket 26 and a third sprocket are provided on the left side of the controller 8. 27. The first sprocket 13, the second sprocket 26, and the third sprocket 27 are connected to each other by the chain 14. The blower 3 blows air to the heater 4 and delivers it to the bottom of the flash evaporator 52 through the pipe on the right side to achieve flash evaporation. Before being delivered into the flash evaporator 52, the temperature needs to be checked to see if it meets the standard. The hot air passes through the one-way air outlet pipe 5 to prevent backflow and blows to the detection chamber 6. The first detector 12 holds a sponge 68. The worker slowly injects a specified amount of water into the sponge 68 and waits for it to absorb it. At this time, the weight of the sponge 68 begins to increase due to the absorption of water, thereby driving the rotator 11 to descend and compress the first spring 10 and the buffer 9 at the bottom. The second sprocket 26 on the left side of the controller 8 can drive the third sprocket 27 to rotate through the chain 14 and drive the first sprocket 13 to rotate, thereby driving the first detector 12 to rotate.

[0033] The controller 8 has a sliding connection to a first rack 22, and a bearing inside the controller 8 connects to a first gear 24. The first gear 24 and the first rack 22 are meshed together. The rotator 11 has a pressing plate 21 inside, which is connected to the top of the first rack 22. The rotation shaft of the second sprocket 26 is connected to the rotation shaft of the first gear 24. When the rotator 11 descends, the pressing plate 21 will press down on the first rack 22 together. At this time, the first gear 24, which is meshed with it, will start to rotate and drive the second sprocket 26 to rotate together. The second sprocket 26 drives the first sprocket 13 to rotate through the chain 14. At this time, the rotation of the first sprocket 13 will drive the first detector 12 to rotate together, thereby changing the first detector 12 from a flat state to a vertical state, thereby increasing the contact area with the hot air and making it easier for the internal moisture to evaporate.

[0034] A support base 15 is provided on the left side of the second support frame 7. A top rod 16 is slidably connected inside the support base 15. The bottom of the top rod 16 is connected to the bottom of the first rack 22. A transition block 17 is provided on the top of the top rod 16. A first connecting plate 18 is connected to the outer bearing of the transition block 17. A second connecting plate 19 is connected to the outer bearing of the first connecting plate 18. The bottom of the second connecting plate 19 is connected to the support base 15. A sprocket 20 is connected to the top bearing of the second connecting plate 19. The sprocket 20 is in contact with the chain 14. However, because the first sprocket 13 will descend with the sprocket 11 during the downward pressing process, the chain 14 cannot continue to be taut by the first sprocket 13, the second sprocket 26, and the third sprocket 27 for transmission. Therefore, when the first rack 22 descends, it will pull the push rod 16 downwards. When the push rod 16 drives the adapter block 17 to descend, the first connecting plate 18 and the second connecting plate 19 will cooperate with each other. The second connecting plate 19 will be driven to open outwards, thereby expanding the chain 14 outwards through the sprocket 20, thus ensuring that the chain 14 is in a taut state, so that the first sprocket 13 can be smoothly driven to rotate. Then the sponge 68 begins to receive hot air. Within a specified time, the first detector 12 will detect its position and the angle of the sprocket 11. If the first detector 12 can return to its original position, it means that the temperature of the hot air meets the standard. Otherwise, the computer will prompt the staff to increase the temperature, achieving a linkage effect and realizing temperature detection at the same time.

[0035] The controller 8 has a second rack 23 slidably connected inside. A second gear 25 is provided on the right side of the first gear 24. The second gear 25 and the second rack 23 are meshed with each other. A first helical gear 28 is provided on the rotating shaft of the second gear 25. A fixing bolt 30 is provided on the front side of the second support frame 7. A sleeve 32 is connected to the bearing inside the fixing bolt 30. A spring rod 31 is slidably connected inside the sleeve 32. A second helical gear 29 is provided on the top of the spring rod 31. The second helical gear 29 and the first helical gear 28 are meshed with each other. The spring rod 31 and the controller 8 are connected by bearings. When the sponge 68 is filled with water, the first rack 22 presses down and drives the first gear 24 to rotate. At the same time, it will drive the second gear 25 to rotate together, so that the second rack 23 meshing with it will descend. The second gear 25 will drive the first helical gear 28 to rotate and drive the second helical gear 29 to rotate. When the second helical gear 29 rotates, it can drive the retractable spring rod 31 and the sleeve 32 to rotate together.

[0036] A third helical gear 33 is provided at the bottom of the sleeve 32. A fixing plate 35 is provided on the front side of the second support frame 7. A feeder 36 is slidably connected above the fixing plate 35. A threaded rod 37 is connected to the internal bearing of the fixing plate 35. The threaded rod 37 and the feeder 36 are threadedly engaged. An adapter 38 is provided on the right side of the threaded rod 37. A fourth helical gear 34 is provided on the right side of the adapter 38. The fourth helical gear 34 is engaged with the third helical gear 33. The base 1 is connected to the first cylinder 39. A second spring 40 is wrapped around the outside of the rod end of the first cylinder 39. The feeder 36 is located above the discharge hopper 41. A storage tank 67 is provided above the base 1. The storage tank 67 is connected to the feeder through a hose. When the second rack 23 descends, the detection plate 43 at the bottom of the second rack 23 will press down on the discharge bin 41. At this time, the first cylinder 39 and the second spring 40 at the bottom will be squeezed. At the same time, the storage bin 67 starts to stir the raw material and delivers the raw material to the feeder 36 through the hose. The feeder 36 will squeeze the raw material into the discharge bin 41. When the second gear 25 rotates, it will drive the first helical gear 28 to rotate. The first helical gear 28 drives the spring rod 31 to rotate through the second helical gear 29 that meshes with it. Since the fourth helical gear 34 and the third helical gear 33 are always meshed through the universal joint, the sleeve 32 of the third helical gear 33 will be pulled when the discharge bin 41 descends. As the sleeve 32 descends, the previously compressed spring rod 31 inside will rebound, lengthening the sleeve 32 and spring rod 31 to form a support. This, combined with the descent of the fixing bolt 30, increases the distance between the second helical gear 29 and the third helical gear 33. The second helical gear 29 is always engaged with the first helical gear 28, and the third helical gear 33 is always engaged with the fourth helical gear 34. When the fourth helical gear 34 rotates, it will drive the threaded rod 37 to rotate, causing the slidably connected feeder 36 to slide forward on the fixed plate 35. This allows the raw material to be evenly injected into the discharge hopper 41, facilitating subsequent feeding. The feeder 42 pushes the material into the flash evaporator 52. When the sponge 68 starts to heat and evaporate the water, the second rack 23 will be driven to slide upward and return to its original position. If the detection plate 43 disengages from the discharge bin 41 at this time, it means that the weight of the raw material in the discharge bin 41 has reached the standard within the specified time, so that it will always press down on the first cylinder 39. Otherwise, it means that the feeder 36 is blocked and cannot squeeze out the specified amount of raw material within the specified time, thus affecting the overall efficiency and requiring workers to clean it. In addition, this device pushes the raw material into the flash evaporator 52 in batches during the flash evaporation operation, realizing temperature detection and detecting the blockage of the feeder 36 at the same time. The sponge 68 designed in this device has enough weight after absorbing a sufficient amount of water to press down on the bottom discharge bin 41.

[0037] The left end of push rod 45 is connected to injector 36 via connecting pipe 44. A rotating wheel 47 is connected to the front bearing of the second support frame 7. A second cylinder 48 is located on the front of the second support frame 7, with its rod end connected to a buckle 49. The buckle 49 and the second support frame 7 are connected by a bearing. An oil supply pipe 50 is located on the front of the rotating wheel 47. A motor 51 is located above the base 1. The flash evaporator 52 is connected to the base 1, and the oil supply pipe 50 is connected to the motor 51. When injector 36 moves to the right, it will push push rod 45 along with it. When the second cylinder 48 retracts its air rod, the latch 49 rotates clockwise. At this time, the left side of the latch 49 disengages from the rotating wheel 47. The push rod 45, in conjunction with the paddle 46, drives the rotating wheel 47 to rotate slightly clockwise and then counterclockwise. The wheel 47 has a lubricator installed inside using existing technology. At this time, the internal lubricator will be activated, allowing the lubricating oil to be squeezed out through the reciprocating rotation and flow from the oil supply pipe 50 to the output end of the motor 51. Since the motor 51 needs to continuously drive the internal stirring plate to rotate during flash evaporation, timely lubrication of the output end during each feeding will reduce the functional wear of the motor 51.

[0038] A feeder 70 is located below the flash evaporator 52, and an injection tube 69 is located at the bottom of the feeder 70. The injection tube 69 is connected to the right side of the discharge hopper 41. A conveying pipe 53 is located above the flash evaporator 52, and a separation chamber 54 is located on the right side of the conveying pipe 53. A filter screen 55 is located inside the conveying pipe 53. A connecting rod 57 is connected to the conveying pipe 53 by bearings. A fifth helical gear 59 is located at the bottom of the conveying pipe 53, and a sixth helical gear 58 is located on the rotating shaft of the turbine 56. The sixth helical gear 58 and the fifth helical gear 59 are meshed together. A turntable 60 is located above the conveying pipe 53. The rotating shaft of 0 is connected to the rotating shaft of the adapter rod 57. The first control rod 61 is connected to the bearing above the turntable 60. The second control rod 62 is connected to the bearing on the left side of the first control rod 61. A sliding sleeve 63 is provided above the conveying pipe 53. The second control rod 62 and the sliding sleeve 63 are slidably connected to each other. The left side of the sliding sleeve 63 is connected to the second detector 64. A third cylinder 65 is provided above the conveying pipe 53. A scraper 66 is provided at the end of the rod of the third cylinder 65. The scraper 66 is in contact with the filter screen 55. When the pusher 42 pushes the material inside the discharge hopper 41 into the flash evaporator 52, the material... The material passes through the injection tube 69 made of flexible tubing, and is then pushed into the flash evaporation cylinder 52 by the feeder 70 for drying. If the drying effect is not up to standard, even if the hot air temperature is up to standard, the flash evaporation effect of the internal raw materials cannot be guaranteed. Furthermore, if the air force is too strong, it can still be blown to the rear separation zone. At this time, the raw materials cannot be completely dried, affecting the effect. They remain in clumps and are intercepted by the filter screen 55. After a period of time, the filter screen 55 will become clogged after filtering out the raw material clumps that do not meet the specifications, thus preventing the hot air from being discharged. Under normal conditions, when the hot air is blown out, it will drive the turbine 56 to rotate. The turbine 56 drives the fifth helical gear 59 to rotate. The sixth helical gear 58 rotates, causing the adapter rod 57 to drive the turntable 60 to rotate. The turntable 60 drives the first control rod 61 and the second control rod 62 to cooperate, causing the second control rod 62 to move like a piston within the sliding sleeve 63. The second detector 64 will detect the frequency of the piston movement in real time, thereby determining the rotational speed of the turbine 56. If the reciprocating speed slows down, it means that the filter screen 55 is clogged. The third cylinder 65 will be automatically activated to push the scraper 66 to remove the clogged material from the filter screen 55 and notify the staff to make adjustments. This achieves the function of detecting the flash evaporation effect of the raw material and can automatically clean the filter screen 55.
