Description

Technical Field

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

[0002] With the rapid development of my country's steel industry, the welding material industry has also developed rapidly. Sintered flux has been widely used in the construction of bridges, oil pipelines, shipbuilding, building steel structures, boiler pressure vessels, offshore platforms, and nuclear power. 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 the barrel body is a truncated cone structure, and the outer part of the barrel body is provided with a transmission mechanism for driving the barrel body to rotate horizontally; the inner part of the barrel body is provided with a partition, and the partition divides the inner part of the barrel body into two parts, and the edge of the partition is provided with a first discharge port connecting the granulation area and the drying area; the inner part of the barrel body is penetrated and inserted with a main shaft along the central axis direction; the inner part of the main shaft located in the granulation area is provided with a cavity to form a feeding channel, and the side wall of the main shaft near the end of the granulation area is provided with a feeding port communicating with the feeding channel, and a number of turning plates are fixedly provided on the side wall of the granulation area; the inner part of the main shaft located in the drying area is provided with a cavity to form an air inlet channel, and the side wall of the main shaft is provided with a number of air holes communicating with the air inlet channel; the end of the drying area is provided with a second discharge port. The granulation and drying equipment integrates granulation and drying, and has high granulation efficiency.

[0003] However, after drying, the temperature of the sintered flux particles is relatively high, while the surrounding environment is usually relatively low in temperature and contains a certain amount of humidity. According to the principles of heat transfer and moisture diffusion, the moisture on the surface of the particles tends to be redistributed due to temperature and humidity differences. When the distance between particles is small, moisture may accumulate at the contact points of the particles, thereby increasing the viscosity between the 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, the particles stay at high temperature for too long, which will allow the surface moisture to 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 of sintered flux being prone to adhesion.

[0014] An automatic drying method for sintered flux comprises the following steps: S1: Add granulated sintered flux from the feeding port; S2: The semi-arc heating cover heats the first storage barrel, and then the first output end of the power mechanism drives the first central shaft to rotate, and the rotation of the first central shaft drives all the disturbance rods to stir and sinter the flux particles to prevent the material from agglomerating. In addition, when drying is in progress, the excess water is converted into steam and discharged from the exhaust port; S3: The dried sintered flux particles enter the second storage barrel from the discharge port.

[0015] Compared with the prior art, the present invention has the following beneficial effects: First, the nozzle at the bottom of the first storage barrel sprays to break the particles from adhering to the barrel wall, the disturbance plate stirs and blows away the lumps, and the vibration motor shakes at high frequency to eliminate dead corners; the second storage barrel rotates in the opposite direction to form a staggered movement with the stirring bar, the spoiler bar turns over the material, and the rotating airflow from the air nozzle blows away the agglomeration. From drying to cooling, the mechanical structure actively eliminates the risk of lumps, ensuring that the flux always remains in an ideal state of looseness and uniformity.

[0016] Second: The hot air blower constructs a "bottom blowing + side spraying" hot air cycle through the transfer arc plate and the disturbance plate. The semi-arc heating cover accurately heats the upper half to avoid overburning, and the spiral blades have differentiated pitches to control the material travel speed. This three-dimensional heating method allows the flux particles to fully contact the heat flow in the dynamic state, and the water evaporates more thoroughly and is heated evenly, effectively avoiding local overburning and ensuring stable flux composition and consistent particle size.

[0017] Third: The discharge port of the partition plate and the air nozzle of the transfer ring form an airflow barrier to prevent material backflow; the spiral spoiler bar and the inclined discharge port design of the second storage barrel, combined with the rotation of the barrel body, naturally push the material to avoid accumulation in the cooling section, ensuring a zero-retention design for the entire process from feeding to discharging, greatly reducing manual intervention and ensuring the reliability of 24-hour automated production.

A feeding port 6 is provided at the end near the first cover plate 7, a partition plate 3 is coaxially fixedly arranged at the end of the first storage barrel 2 away from the first cover plate 7, a discharge port 4 is provided at the lower edge of the partition plate 3, a second cover plate 29 is elastically slidably arranged on the second support frame 27, a discharge port 37 is provided on the second cover plate 29, one end of the second storage barrel 28 is coaxially connected to the partition plate 3 for rotation, and the other end is coaxially connected to the second cover plate 29 for rotation, a vibration motor 5 is fixedly arranged on the partition plate 3, and 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 fixedly arranged on the first central shaft 8 at equal intervals, a plurality of disturbance rods 14 annularly arranged on each mounting ring 13, and a semi-arc 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 carrying rings 32 equally arranged on the second central shaft 30, a stirring bar 33 annularly arranged on each carrying 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.

[0022] When the device is in operation, the granulated sintered flux is fed from the feeding port 6. Then, 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 axis 8 to rotate, so that all the disturbance rods 14 stir the sintered flux particles, effectively preventing the material from agglomerating. During the drying process, the excess water is converted into steam and 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 axis 8 drives the second central axis 30 to rotate, driving the stirring bar 33 to stir the particles. At the same time, the second output end of the power mechanism drives the second storage barrel 28 to rotate in the opposite direction of the second central axis 30, and the air cooler 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 is started, driving the first storage barrel 2, the partition plate 3 and the second storage barrel 28 to shake, further preventing the agglomeration of the sintered flux particles. Finally, the processed sintered flux particles are discharged from the discharge port 37 .

[0023] In order to ensure that the sintered flux particles can have a better drying effect in the first storage barrel 2, the following features are also specifically provided: The drying mechanism also includes a hot air blower 25 fixedly arranged on the side of 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 evenly spaced 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 interior of the transfer arc plate 20 is a hollow structure, the air inlet pipe 22 is coaxially slidably connected with the air outlet pipe 26, and each air nozzle 21 extends into the interior of the first storage barrel 2.

[0024] When the device is running, 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 is finally sprayed into the first storage barrel 2 from the air nozzle 21. With the vibration of the vibration motor 5 and the stirring of the disturbance rod 14, the sintered flux particles can be evenly broken up to accelerate the drying. The hot air sprayed from the air nozzle 21 also prevents the sintered flux particles from adhering to the bottom of the first storage barrel 2 (because the first storage barrel 2 is placed horizontally, the bottom here refers to the lower half of the first storage barrel 2).

[0025] In order to further enhance the drying effect in the first storage barrel 2, the following features are specifically provided: The drying mechanism also includes a transfer air box 18 fixedly arranged on the first cover plate 7 and a disturbance plate 15 fixedly arranged at the end of each disturbance rod 14. A blowing chamber 9 is coaxially opened at the center of the first central axis 8. The transfer air box 18 is dynamically sealed with the first central axis 8. A plurality of air inlets 10 are opened in a ring shape at one end of the first central axis 8 close to the transfer air box 18. The disturbance plate 15 is tilted and twisted along the spiral line of the first storage barrel 2. Each disturbance plate 15 is a hollow structure. A plurality of air outlet holes 16 are evenly spaced on one side of each disturbance plate 15 close to the partition plate 3. The disturbance plate 15 is connected to the inside of the blowing chamber 9 through the disturbance rod 14 and the mounting ring 13. The transfer air box 18 is connected to the air inlet pipe 22 through a hose.

[0026] When the device is running, the hot air in the air inlet pipe 22 enters the adapter air box 18 through the hose, and then enters the blowing chamber 9 from the air inlet 10, and then enters the mounting ring 13, the disturbance rod 14, and the disturbance plate 15 in sequence, and finally is ejected from the air outlet 16. The ejected hot air can assist in drying the sintered flux particles, and because the blowing direction of the air outlet 16 is toward the partition plate 3, it will also help the sintered flux particles to surge toward the partition plate 3.

[0027] In order to ensure that the sintered flux particles always have a tendency to move toward the partition plate 3 when drying in the first storage barrel 2, the following features are specifically provided: The drying mechanism also includes a first spiral blade 11 and a second spiral blade 12. The first spiral blade 11 is coaxially fixed at one end of the first central axis 8 close to the feeding port 6, and the second spiral blade 12 is coaxially fixed at one end of the first central axis 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, and the spiral twisting direction of each disturbance plate 15 along the spiral line of the first storage barrel 2 is consistent with the spiral direction of the first spiral blade 11 and the second spiral blade 12.

[0028] When the device is running, the rotation of the first central axis 8 will drive the first spiral blade 11 and the second spiral blade 12 to rotate. 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 be accelerated to enter the middle position of the first storage barrel 2, and then the rotating disturbance plate 15 will be used to stir the sintered flux particles. The semi-arc heating hood 19, the air nozzle 21 and the air outlet 16 will be used to accelerate the drying process of the sintered flux particles. In addition, since the disturbance plate 15 has an inclined stirring, when the disturbance plate 15 stirs the sintered flux particles, it can also continuously drive the sintered flux particles to surge toward 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.

[0029] In order to show the detailed structure of the power mechanism, the following features are also set: The power mechanism includes a driving motor 24 fixedly arranged on the first support frame 1, a reversing gear box 17 fixedly arranged on the first cover plate 7, a power gear 35 coaxially fixedly arranged on the end of the second center shaft 30, a power ring gear 43 coaxially fixedly arranged on the second storage barrel 28, and a plurality of transfer gears 36 rotatably arranged on the second cover plate 29. The transfer gear 36 meshes with the power ring gear 43 and the power gear 35. The power output shaft of the reversing gear box 17 is coaxially fixedly connected to the first center shaft 8, and the power input shaft of the reversing gear box 17 is keyed to the power output shaft of the driving motor 24.

[0030] The power output shaft of the reversing gear box 17 is the first output end of the power mechanism, and the power ring gear 43 is the second output end of the power mechanism.

[0031] When the device is running, the driving motor 24 drives the first central shaft 8 to rotate through the reversing gear box 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 power gear 35 rotates through the transfer gear 36 to drive the power ring gear 43 to perform a deceleration rotation in the opposite direction of the power gear 35, and then the power ring gear 43 rotates to drive the second storage barrel 28 to rotate (here, the transmission of the power gear 35, the transfer gear 36 and the power ring gear 43 refers to the planetary gear transmission principle, in addition to the mature existing structure, it will not be repeated here).

[0032] In order to ensure that the sintered flux particles always have a tendency to flow toward the discharge port 37 when the sintered flux particles are cooled in the second storage barrel 28, the following features are specifically provided: The inner wall of the second storage barrel 28 is provided with a plurality of groups of spoiler bars 38 evenly spaced along the circumferential direction, each group of spoiler bars 38 is composed of a plurality of spoiler bumps 39, and all spoiler bumps 39 are spaced along a spiral line on the inner wall of the second storage barrel 28, and the axis of the spiral line coincides with the axis of the second storage barrel 28.

[0033] When the second storage barrel 28 rotates, the spoiler protrusions 39 can block the sintered flux particles from surging. In addition, due to the spoiler baffles 38 formed by the spoiler protrusions 39, the second storage barrel 28 can continuously transport the sintered flux particles to the discharge port 37 when rotating.

[0034] In order to ensure that the cold air blown out from the cold air blower 44 can be more evenly distributed inside the second storage barrel 28, the following features are also specifically provided: The cooling mechanism also includes a supporting cross plate 46 slidably arranged on the second supporting frame 27, a transfer tube 47 fixedly arranged on the supporting cross plate 46, a cold air chamber 31 coaxially opened on the second central axis 30, and a plurality of rows of cold air holes 34 equally spaced on each stirring bar 33. The transfer tube 47 is connected to the cold air fan 44 through a hose, and one end of the second central axis 30 close to the transfer tube 47 is rotatably connected to the transfer tube 47. The second central axis 30 is dynamically sealed with the transfer tube 47, and each stirring bar 33 is a hollow structure and is connected to the cold air chamber 31 through a supporting ring 32.

[0035] When the device is running, the cold air blown by the cold air fan 44 enters the transfer tube 47 through the hose, then enters the cold air chamber 31, finally enters the carrying ring 32 and is finally blown out from the cold air hole 34 on the stirring bar 33. In conjunction with the rotating stirring bar 33 and the rotating second storage barrel 28, the sintered flux particles can be broken up and cooled quickly to prevent agglomeration. When the vibration motor 5 is running, the supporting cross plate 46 slides adaptively on the second supporting frame 27 to ensure the normal operation of the equipment.

[0036] 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 also specifically provided: The cooling mechanism also includes a transfer ring 40 coaxially fixed on the second storage barrel 28, a plurality of air nozzles 41 arranged in a ring shape on the transfer ring 40, a limiting ring box 42 fixed on the partition plate 3, and a connecting pipe 45 fixed on the limiting ring box 42. The transfer ring 40 is rotatably connected to the limiting ring box 42, one end of the connecting pipe 45 is connected to the interior of the limiting ring box 42, and the other end is connected to the cold air fan 44. The axis of each air nozzle 41 is inclined toward the direction of the second cover plate 29 and obliquely intersects with the axis of the transfer ring 40, and each air nozzle 41 extends into the interior of the second storage barrel 28.

[0037] When the device is running, the cold air sent from the air cooler 44 enters the limit ring box 42 through the connecting pipe 45, and then is sprayed into the second storage barrel 28 from the air nozzle 41 on the transfer ring 40. As the second storage barrel 28 rotates during cooling, all the air nozzles 41 can be driven to rotate and spray air, which can not only assist in cooling, but also blow the sintered flux particles toward the discharge port 37 to prevent the sintered flux particles from accumulating in the second storage barrel 28.

[0038] An automatic drying method for sintered flux comprises the following steps: S1: feeding the granulated sintered flux from the feeding port 6; S2: The semi-arc 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, and the rotation of the first central shaft 8 drives all the disturbance rods 14 to stir and sinter the flux particles to prevent the material from agglomerating. In addition, when drying is in progress, the excess water is converted into steam and discharged from the exhaust port 23; S3: The dried sintered flux particles enter the second storage barrel 28 from the discharge port 4. At this time, the second central shaft 30 is driven to rotate by the first central shaft 8, 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 in a direction opposite to the second central shaft 30. At the same time, the air cooler 44 blows cold air into the second storage barrel 28 to cool the sintered flux particles. S4: During the drying and cooling, the vibration motor 5 is started to vibrate the first storage barrel 2, the partition plate 3 and the second storage barrel 28 to further prevent the sintered flux particles from agglomerating; S5: The processed sintered flux particles are discharged from the discharge port 37 .

[0039] The working principle of this device is as follows: after the equipment is started, the sintered flux falls into the first storage barrel 2 from the top feeding port 6, and the air nozzle 21 of the bottom transfer arc plate 20 sprays hot air upwards, forming up and down convection with the top semi-arc heating cover 19. The driving motor 24 drives the first central shaft 8 to rotate through the reversing gear box 17, and the first spiral blade 11 on the shaft pushes the material to the middle, and the second spiral blade 12 accelerates the conveying to the partition plate 3. The disturbance plate 15 at the end of the disturbance rod 14 stirs and sprays hot air from the air outlet 16 to blow away the sticking particles. After the moisture is discharged through the exhaust port 23, the dry 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 bar 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 opposite direction at a low speed, and the cold air of the cold air blower 44 is uniformly ejected from the cold air holes 34 on the stirring bar 33 through the transfer tube 47 and the cold air cavity 31, and cooperates with the inner wall spoiler bar 38 to push the material to move to the discharge port 37. The full-range vibration motor 5 shakes the first storage barrel 2, the partition plate 3 and the second storage barrel 28, and the transfer ring 40 air nozzle 41 ejects air as the barrel rotates, and finally the cooled sintered flux particles are smoothly discharged from the discharge port 37.
