Description

Technical Field

[0001] The present invention relates to the technical field of drying equipment, and specifically relates to an automatic drying equipment and drying method for sintered flux. Background Art

[0002] With the rapid development of China's steel industry, the welding consumables industry has also developed rapidly. Sintered flux is widely used in the construction of bridges, oil pipelines, shipbuilding, building steel structures, boilers and pressure vessels, offshore platforms, and nuclear power fields. The Chinese patent with the publication number (CN214065532U) discloses a continuous granulation and drying equipment for mass production of sintered flux, including a barrel body; the barrel body is horizontally arranged and has a frustum-shaped structure, and a transmission mechanism for driving the barrel body to rotate horizontally is arranged outside the barrel body; a partition is arranged inside the barrel body, and the partition divides the inside of the barrel body into two parts, and a first discharge port communicating the granulation area and the drying area is arranged at the edge of the partition; a main shaft is inserted through the barrel body along its central axis direction; a cavity is arranged inside the main shaft in the granulation area to form a feeding channel, and a feeding port communicating with the feeding channel is arranged on the side wall of the main shaft near the end of the granulation area, and a plurality of turning plates are fixed on the side wall of the granulation area; a cavity is arranged inside the main shaft in the drying area to form an air inlet channel, and a plurality of air holes communicating with the air inlet channel are arranged on the side wall of the main shaft; a second discharge port is arranged at the end of the drying area. This granulation and drying equipment integrates granulation and drying and has high granulation efficiency.

[0003] However, after the sintered flux particles are dried, their temperature is relatively high, while the surrounding environment usually has a relatively low temperature and contains a certain amount of humidity. According to the principles of heat transfer and moisture diffusion, the moisture on the particle surface tends to redistribute due to the temperature difference and humidity difference. When the distance between particles is small, moisture may accumulate at the particle contact points, thereby increasing the adhesion between particles and causing adhesion. In addition, in actual production, if the dried sintered flux particles are not cooled in time, or the cooling speed is too slow, and the particles stay at a high temperature for too long, the surface moisture will have enough time to redistribute and cause adhesion. The drying equipment disclosed in the above patent cannot solve this problem, so it is necessary to design a new type of drying equipment to solve the problem that sintered flux is prone to adhesion. Summary of the Invention

[0004] Based on this, in view of the problems in the prior art, it is necessary to provide an automatic drying equipment and drying method for sintered flux.

[0014] An automatic drying method for sintered flux, comprising the following steps:

[0015] S1: Put the granulated sintered flux into the feeding port;

[0016] S2: The semi-circular heating cover heats the first storage barrel, and then the first output end of the power mechanism drives the first central shaft to rotate. The rotation of the first central shaft drives all the stirring rods to stir the sintered flux particles to prevent material caking. In addition, when drying, the excess moisture turns into steam and is discharged from the exhaust port;

[0017] S3: The dried sintered flux particles enter the second storage barrel from the discharge port. At this time, the second central shaft is driven to rotate by the first central shaft, and then drives all the stirring bars to rotate to agitate the sintered flux particles. And the second output end of the power mechanism drives the second storage barrel to rotate at a reduced speed in the opposite direction to the rotation direction of the second central shaft. At the same time, the cold air blower blows cold air into the second storage barrel to cool the sintered flux particles;

[0018] S4: When the above drying and cooling are in progress, the vibration motor is started to drive the first storage barrel, the partition plate and the second storage barrel to vibrate, further preventing the sintered flux particles from caking;

[0019] S5: The processed sintered flux particles are discharged from the discharging port.

[0020] The beneficial effects of the present invention compared with the prior art are:

[0021] First: The air nozzles at the bottom of the first storage barrel spray to break the adhesion between the particles and the barrel wall. The stirring plate stirs and blows the caked mass while stirring. The vibration motor vibrates at a high frequency to eliminate dead corners; The second storage barrel rotates in the opposite direction to form a dislocation with the stirring bars, the flow disturbing bars turn over the materials, and the rotating air flow of the jet nozzles blows away the agglomeration. In each link from drying to cooling, the risk of caking is actively eliminated through the mechanical structure, ensuring that the flux always maintains an ideal state of being loose and uniform.

[0022] Second: The hot air blower constructs a "bottom blowing + side spraying" hot air circulation through the transfer arc plate and the disturbance plate. The semi-circular heating cover precisely heats the upper half to avoid overburning, and the spiral blades with different pitches control the advancing speed of the material. This three-dimensional heating method enables the flux particles to fully contact the heat flow dynamically, with more thorough evaporation of moisture and uniform heating, effectively avoiding local overburning and ensuring stable flux composition and consistent particle size.

[0023] Third: The outlet of the partition plate and the jet nozzles of the transfer ring form an air flow barrier to prevent material backflow; the spiral turbulence bars of the second storage barrel and the discharge port are inclined, and together with the rotation of the barrel, they naturally push the material, avoiding accumulation in the cooling section, ensuring a non-stagnant design throughout the process from feeding to discharging, greatly reducing manual intervention, and ensuring the reliability of 24-hour automated production.

Detailed implementation manners

[0033] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0034] Refer to Figures 1 to 8 :

[0035] An automatic drying device for sintered welding flux, comprising a first support frame 1, a second support frame 27, a first cover plate 7, a first storage barrel 2, a partition plate 3, a vibration motor 5, a second cover plate 29, a second storage barrel 28, a drying unit and a power mechanism. The first support frame 1 and the second support frame 27 are symmetrically arranged. The first cover plate 7 is elastically slidably arranged on the first support frame 1. The first storage barrel 2 is coaxially fixedly connected to the first cover plate 7. Exhaust ports 23 are symmetrically arranged on the side wall of the first storage barrel 2. A vertically upward feeding port 6 is arranged at the end of the first storage barrel 2 close to the first cover plate 7. The partition plate 3 is coaxially fixedly arranged at the end of the first storage barrel 2 far from the first cover plate 7. A discharge port 4 is arranged at the lower half edge of the partition plate 3. The second cover plate 29 is elastically slidably arranged on the second support frame 27. A discharge port 37 is arranged on the second cover plate 29. One end of the second storage barrel 28 is coaxially rotatably connected to the partition plate 3, and the other end is coaxially rotatably connected to the second cover plate 29. The vibration motor 5 is fixedly arranged on the partition plate 3. The drying unit includes a drying mechanism and a cooling mechanism. The drying mechanism includes a first central shaft 8 coaxially arranged in the first storage barrel 2, a plurality of mounting rings 13 coaxially and equally spacedly fixedly arranged on the first central shaft 8, a plurality of disturbing rods 14 annularly arranged on each mounting ring 13, and a semi-circular heating cover 19 fixedly arranged above the first storage barrel 2. One end of the first central shaft 8 is rotatably connected to the first cover plate 7, and the other end is rotatably connected to the partition plate 3. The cooling mechanism includes a second central shaft 30 coaxially arranged in the second storage barrel 28, a plurality of bearing rings 32 equally spacedly arranged on the second central shaft 30, stirring bars 33 annularly arranged on each bearing ring 32, and a cold air blower 44 fixedly arranged on the second support frame 27. One end of the second central shaft 30 is coaxially fixedly connected to the first central shaft 8, and the other end is rotatably connected to the second cover plate 29. The cold air blower 44 is used to blow cold air into the second storage barrel 28. The power mechanism includes a first output end and a second output end. The first output end is used to drive the first central shaft 8 to rotate, and the second output end is used to drive the second storage barrel 28 to rotate.

[0036] When the device is in operation, the granulated sintered flux is fed into the feeding port 6. Immediately afterwards, the semi-arc heating cover 19 starts to heat the first storage barrel 2, and the first output end of the power mechanism operates synchronously, driving the first central shaft 8 to rotate, so that all the stirring rods 14 stir the sintered flux particles, effectively preventing the material from caking. During the drying process, the excess moisture turns into steam and is discharged from the exhaust port 23. The dried sintered flux particles enter the second storage barrel 28 through the discharge port 4. At this time, the first central shaft 8 drives the second central shaft 30 to rotate, driving the stirring bars 33 to agitate the particles. At the same time, the second output end of the power mechanism drives the second storage barrel 28 to rotate at a reduced speed in the opposite direction to the rotation direction of the second central shaft 30, and the cold air blower 44 also blows cold air into the second storage barrel 28 to cool the sintered flux particles. During the entire drying and cooling process, the vibration motor 5 starts, driving the first storage barrel 2, the partition plate 3 and the second storage barrel 28 to vibrate, further preventing the sintered flux particles from caking. Finally, the processed sintered flux particles are discharged from the discharge port 37.

[0037] In order to ensure better drying effect of the sintered flux particles in the first storage barrel 2, the following features are specifically set:

[0038] The drying mechanism further includes a hot air blower 25 fixedly arranged beside the first support frame 1, a transfer arc plate 20 fixedly arranged at the bottom of the first storage barrel 2, a plurality of rows of air nozzles 21 arranged at equal intervals on the inner wall of the transfer arc plate 20, an air inlet pipe 22 arranged at the bottom of the transfer arc plate 20, and an air outlet pipe 26 arranged on the hot air blower 25. The inside of the transfer arc plate 20 is a hollow structure, the air inlet pipe 22 and the air outlet pipe 26 are coaxially and slidably connected, and each air nozzle 21 extends into the first storage barrel 2.

[0039] When the device is in operation, the hot air blower 25 generates hot air, which enters the transfer arc plate 20 through the air outlet pipe 26 and the air inlet pipe 22, and finally sprays into the first storage barrel 2 from the air nozzles 21. Cooperating with the vibration of the vibration motor 5 and the stirring of the stirring rods 14, the sintered flux particles can be evenly dispersed, accelerating the drying, and the hot air sprayed from the air nozzles 21 also prevents the sintered flux particles from adhering to the bottom of the first storage barrel 2 (since the first storage barrel 2 is horizontally placed, the bottom here refers to the lower half of the first storage barrel 2).

[0040] In order to further enhance the drying effect in the first storage barrel 2, the following features are specifically set:

[0041] The drying mechanism further includes a transfer air box 18 fixedly arranged on the first cover plate 7 and a stirring plate 15 fixedly arranged at the end of each stirring rod 14. A blowing cavity 9 is coaxially formed at the center of the first central shaft 8. The transfer air box 18 is in dynamic seal with the first central shaft 8. A plurality of air inlets 10 are annularly formed at one end of the first central shaft 8 close to the transfer air box 18. The stirring plates 15 are inclined and twisted along the spiral line of the first storage barrel 2. Each stirring plate 15 is of a hollow structure. A plurality of air outlet holes 16 are equidistantly formed on one side of each stirring plate 15 close to the partition plate 3. The stirring plates 15 are communicated with the inside of the blowing cavity 9 through the stirring rods 14 and the mounting ring 13. The transfer air box 18 is connected to the air inlet pipe 22 through a hose.

[0042] During the operation of the device, the hot air in the air inlet pipe 22 enters the transfer air box 18 through the hose, then enters the blowing cavity 9 from the air inlets 10, and then sequentially enters the mounting ring 13, the stirring rods 14, and the stirring plates 15, and finally sprays out from the air outlet holes 16. The sprayed hot air can assist in drying the sintered flux particles. And since the blowing direction of the air outlet holes 16 is towards the partition plate 3, this will also help the sintered flux particles to surge towards the partition plate 3.

[0043] In order to ensure that the sintered flux particles always tend to move towards the partition plate 3 during drying in the first storage barrel 2, the following features are specifically set:

[0044] The drying mechanism further includes a first spiral blade 11 and a second spiral blade 12. The first spiral blade 11 is coaxially and fixedly arranged at one end of the first central shaft 8 close to the feeding port 6. The second spiral blade 12 is coaxially and fixedly arranged at one end of the first central shaft 8 close to the partition plate 3. The pitch of the first spiral blade 11 is greater than the pitch of the second spiral blade 12. The spiral directions of the first spiral blade 11 and the second spiral blade 12 are the same. The spiral twisting direction of each stirring plate 15 along the spiral line of the first storage barrel 2 is the same as the spiral directions of the first spiral blade 11 and the second spiral blade 12.

[0045] During the operation of the device, the rotation of the first central shaft 8 will drive the rotation of the first spiral blade 11 and the second spiral blade 12. The pitch of the first spiral blade 11 is greater than the pitch of the second spiral blade 12. Therefore, the sintered flux particles fed from the feeding port 6 will accelerate into the middle position of the first storage barrel 2. Then, combined with the rotating stirring plates 15, the sintered flux particles will be stirred. And combined with the semi-circular heating cover 19, the air nozzles 21, and the air outlet holes 16, the drying process of the sintered flux particles is accelerated. In addition, due to the inclined stirring of the stirring plates 15, when the stirring plates 15 stir the sintered flux particles, they can continuously drive the sintered flux particles to surge towards the second spiral blade 12. When the sintered flux particles are sent out by the second spiral blade 12, the drying of the sintered flux particles has been completed. Subsequently, the dried sintered flux particles enter the second storage barrel 28 from the discharge port 4 for cooling.

[0046] To show the detailed structure of the power mechanism, the following features are specifically set:

[0047] The power mechanism includes a driving motor 24 fixedly arranged on the first support frame 1, a reversing gearbox 17 fixedly arranged on the first cover plate 7, a power gear 35 coaxially and fixedly arranged at the end of the second central shaft 30, a power gear ring 43 coaxially and fixedly arranged on the second storage barrel 28, and a number of transfer gears 36 rotatably arranged on the second cover plate 29. The transfer gears 36 mesh with the power gear ring 43 and the power gear 35. The power output shaft of the reversing gearbox 17 is coaxially and fixedly connected to the first central shaft 8, and the power input shaft of the reversing gearbox 17 is key-connected to the power output shaft of the driving motor 24.

[0048] The power output shaft of the reversing gearbox 17 is the first output end of the power mechanism, and the power gear ring 43 is the second output end of the power mechanism.

[0049] During the operation of the device, the driving motor 24 drives the first central shaft 8 to rotate through the reversing gearbox 17. The rotation of the first central shaft 8 drives the second central shaft 30 to rotate. The rotation of the second central shaft 30 drives the power gear 35 to rotate. The rotation of the power gear 35 drives the power gear ring 43 to perform a decelerated rotation in the opposite direction to the power gear 35 through the transfer gears 36. Then, the rotation of the power gear ring 43 drives the second storage barrel 28 to rotate (the transmission of the power gear 35, the transfer gears 36, and the power gear ring 43 here refers to the principle of planetary gear transmission. In addition, for mature existing structures, no more details will be elaborated here).

[0050] To ensure that when the sintered flux particles are cooled in the second storage barrel 28, the sintered flux particles always have a tendency to surge towards the discharge port 37, the following features are specifically set:

[0051] Several groups of flow-disturbing rib strips 38 are arranged on the inner wall of the second storage barrel 28 at equal intervals in the circumferential direction. Each group of flow-disturbing rib strips 38 is composed of several flow-disturbing bumps 39. All the flow-disturbing bumps 39 are distributed at intervals along a spiral line on the inner wall of the second storage barrel 28. The axis of the spiral line coincides with the axis of the second storage barrel 28.

[0052] When the second storage barrel 28 rotates, the flow-disturbing bumps 39 can play a role in blocking the sintered flux particles and causing them to surge. In addition, due to the flow-disturbing rib strips 38 formed by the flow-disturbing bumps 39, the second storage barrel 28 can continuously transport the sintered flux particles towards the discharge port 37 during rotation.

[0053] To ensure that the cold air blown out from the cold air blower 44 can be more evenly dispersed into the interior of the second storage barrel 28, the following features are specifically set:

[0054] The cooling mechanism further includes a support cross plate 46 slidably arranged on the second support frame 27, a transfer pipe 47 fixedly arranged on the support cross plate 46, a cold air cavity 31 coaxially opened on the second central shaft 30, and a number of rows of cold air holes 34 equally spaced on each stirring bar 33. The transfer pipe 47 is connected to the cold air blower 44 through a hose. One end of the second central shaft 30 close to the transfer pipe 47 is rotationally connected to the transfer pipe 47, and the second central shaft 30 is in dynamic seal with the transfer pipe 47. Each stirring bar 33 is of a hollow structure and is communicated with the cold air cavity 31 through a bearing ring 32.

[0055] During the operation of the device, the cold air blown by the cold air blower 44 enters the transfer pipe 47 through the hose, then enters the cold air cavity 31, and finally enters the bearing ring 32 and is finally blown out from the cold air holes 34 on the stirring bar 33. Cooperating with the rotating stirring bar 33 and the rotating second storage barrel 28, the sintered flux particles can be scattered and quickly cooled to prevent caking. And when the vibration motor 5 is running, the support cross plate 46 slides adaptively on the second support frame 27 to ensure the normal operation of the device.

[0056] In order to further ensure that the sintered flux particles entering the second storage barrel 28 from the discharge port 4 will not flow back, the following features are specifically set:

[0057] The cooling mechanism further includes a transfer ring 40 coaxially and fixedly arranged on the second storage barrel 28, a number of jet nozzles 41 arranged in a ring on the transfer ring 40, a limit ring box 42 fixedly arranged on the partition plate 3, and a connecting pipe 45 fixedly arranged on the limit ring box 42. The transfer ring 40 is rotationally connected to the limit ring box 42. One end of the connecting pipe 45 is communicated with the inside of the limit ring box 42, and the other end is connected to the cold air blower 44. The axis of each jet nozzle 41 inclines towards the direction of the second cover plate 29 and intersects the axis of the transfer ring 40 obliquely, and each jet nozzle 41 extends into the second storage barrel 28.

[0058] During the operation of the device, the cold air sent out from the cold air blower 44 enters the limit ring box 42 through the connecting pipe 45, and then is sprayed into the second storage barrel 28 from the jet nozzles 41 on the transfer ring 40. Since the second storage barrel 28 will rotate during the cooling process, all the jet nozzles 41 can be driven to rotate and spray air. On the one hand, it can assist in cooling, and on the other hand, it can blow the sintered flux particles towards the discharge port 37 to prevent the sintered flux particles from accumulating in the second storage barrel 28.

[0059] An automatic drying method for sintered flux includes the following steps:

[0060] S1: Put the granulated sintered flux into the feeding port 6;

[0061] S2: The semi-circular heating cover 19 heats the first storage barrel 2, and then the first output end of the power mechanism drives the first central shaft 8 to rotate. The rotation of the first central shaft 8 drives all the stirring rods 14 to stir and sinter the flux particles to prevent material caking. In addition, when drying, the excess moisture turns into steam and is discharged from the exhaust port 23;

[0062] S3: The dried and sintered flux particles enter the second storage barrel 28 from the discharge port 4. At this time, the second central shaft 30 is driven by the first central shaft 8 to rotate, thereby driving all the stirring bars 33 to rotate, stirring the sintered flux particles, and the second output end of the power mechanism drives the second storage barrel 28 to rotate at a reduced speed in the opposite direction to the rotation direction of the second central shaft 30. At the same time, the cold air blower 44 blows cold air into the second storage barrel 28 to cool the sintered flux particles;

[0063] S4: When the above-mentioned drying and cooling are in progress, the vibration motor 5 starts, driving the first storage barrel 2, the partition plate 3, and the second storage barrel 28 to vibrate, further preventing the sintered flux particles from caking;

[0064] S5: The processed sintered flux particles are discharged from the discharge port 37.

[0065] The working principle of this device is as follows: After the device is started, the sintered flux falls from the feeding port 6 at the top of the first storage barrel 2. The nozzles 21 of the air nozzles on the bottom transfer arc plate 20 spray hot air upward, forming an up-and-down convection with the top semi-circular heating cover 19. The drive motor 24 drives the first central shaft 8 to rotate through the reversing gearbox 17. The first spiral blade 11 on the shaft pushes the material towards the middle, and the second spiral blade 12 accelerates the transportation to the partition plate 3. The stirring plate 15 at the end of the stirring rod 14 sprays hot air from the air outlet holes 16 while stirring, dispersing the adhered particles. After the moisture is discharged through the exhaust port 23, the dried material enters the second storage barrel 28 through the discharge port 4 on the partition plate 3. At this time, the first central shaft 8 synchronously drives the stirring bars 33 of the second central shaft 30 to stir the particles. The power gear ring 43 drives the second storage barrel 28 to rotate in the reverse direction at a low speed. The cold air of the cold air blower 44 is evenly sprayed from the cold air holes 34 on the stirring bars 33 through the transfer pipe 47 and the cold air cavity 31, and the inner wall turbulence blocking bars 38 are used to push the material towards the discharge port 37. The vibration motor 5 vibrates the first storage barrel 2, the partition plate 3, and the second storage barrel 28 throughout the process. The air nozzles 41 of the transfer ring 40 spray air as the barrel rotates, and finally the cooled sintered flux particles are smoothly discharged from the discharge port 37.
