[0001] The present application relates to the technical field of drying equipment, and in particular to a vibrating fluidized bed for material drying. Background Art

[0018] The vibrating fluidized bed for material drying provided in the present application avoids the problem of material blocking the bed plate during the drying process, realizes rapid drying of the material, and has the following beneficial effects compared with the prior art:

[0019] (1) By setting the fluidized bed plate, hot air outlet and exhaust outlet, the hot gas can contact the material to be dried and take away the solvent in the material, so as to achieve the purpose of drying the material. By setting the through holes in the anti-blocking component to clear the holes during the drying process, it helps to ensure that the hot gas contacts the material to be dried through the through holes, which in turn helps the vibrating fluidized bed to efficiently dry the material. When the anti-blocking component is in operation, the movement trajectory of the connecting rod and the counterweight block when the crankshaft rotates is to make a circular motion while reciprocating up and down, colliding with the fluidized bed plate, causing the fluidized bed plate to vibrate up and down, which not only makes the materials blocked in the multiple through holes on the fluidized bed plate fall off by vibration, but also helps the through holes on the fluidized bed plate to remain unobstructed, thereby ensuring that the hot gas passes through the through holes smoothly and contacts the material to be dried, thereby improving the drying efficiency of the material. At the same time, when there are lumps in the material, the collision of the counterweight block and the fluidized bed plate causes the agglomerated materials on the fluidized bed plate to loosen due to vibration, further improving the drying effect of the material.

[0020] (2) By connecting the first spring between the connecting rod and the counterweight, the first spring can play a certain buffering role on the connection between the connecting rod and the counterweight under long-term operation conditions, thereby preventing the connection between the connecting rod and the counterweight, and the connection between the connecting rod and the crankshaft connecting rod journal from being deformed or loosened due to the long-term upward impact of the counterweight, which is beneficial to the long-term use of the anti-blocking component and the long-term operation of the vibrating fluidized bed.

[0021] (3) By setting a plurality of lifting structures at the bottom of the housing, it is convenient to start the hydraulic cylinder to extend the telescopic end of the hydraulic cylinder, push the housing upward, move the housing away from the support block, and replace the second spring. After the second spring is replaced, the hydraulic cylinder is started again to retract it, so that the housing descends to abut against the support block, and then the hydraulic cylinder is closed to complete the replacement of the second spring. This arrangement improves the degree of automation and convenience when replacing the second spring, while reducing the labor input of personnel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0030] like Figure 1 and Figure 2 As shown, the present application provides a vibrating fluidized bed for material drying, comprising: a shell 1, a feed pipe 110 is arranged at the front end of the left side of the shell 1, a discharge tank 120 is arranged on the right side of the shell 1, a vibration motor 130 is fixedly arranged at the front end of the shell 1, a fluidized bed plate 140 is arranged in the shell 1, a hot air outlet 150 is arranged at the lower part of the shell 1, and a plurality of exhaust outlets 160 are arranged at equal intervals on the top of the shell 1.

[0031] The outer periphery of the fluidized bed plate 140 is connected to the inner wall of the shell 1 , and the fluidized bed plate 140 is inclined downward along the direction from the feed pipe 110 to the discharge tank 120 . A plurality of through holes penetrate the fluidized bed plate 140 , and the outlet end of the feed pipe 110 is located above the fluidized bed plate 140 .

[0032] A plurality of anti-blocking components are also provided on the upper part of the fluidized bed plate 140 in the vibrating fluidized bed, and the anti-blocking components include a motor 210, a crankshaft 220, a connecting sleeve 230, a connecting rod 240 and a counterweight 250. The motor 210 is located on the outer side of the shell 1, and the output end is connected to one end of the main journal 221 of the crankshaft 220. The main journal 221 at the other end of the crankshaft 220 horizontally penetrates the shell 1 and is rotatably connected to the inner wall of the shell 1. The connecting sleeve 230 is rotatably sleeved on the outer periphery of the connecting rod journal 222 of the crankshaft 220. One end of the connecting rod 240 is fixedly connected to the outer side wall of the connecting sleeve 230, and the other end of the connecting rod 240 is fixedly connected to the counterweight 250.

[0033] Specifically, the material to be dried is fed to the fluidized bed plate 140 of the shell 1 through the feed pipe 110, and the vibration motor 130 is used to provide power, so that the shell 1 and the fluidized bed plate 140 vibrate, and the fluidized bed plate 140 is tilted downward from the feed pipe 110 to the discharge tank 120, so that the material can move toward the discharge tank 120 while vibrating, so as to facilitate the smooth output of the material. A plurality of hot air vents 150 are arranged at equal intervals at the lower part of the shell 1, which are used to input hot gas into the shell 1 through the hot air vents 150, and the plurality of hot air vents 150 are located below the fluidized bed plate 140, and the hot gas flows from the bottom of the fluidized bed plate 140 through the plurality of through holes penetrating the fluidized bed plate 140 to the top of the fluidized bed plate 140. Since the material to be dried is placed on the fluidized bed plate 140, the rising hot gas contacts the material to be dried on the fluidized bed plate 140 and performs heat exchange. As the temperature of the material to be dried rises, the temperature of the solvent mixed therein also rises and evaporates into gas, and the gaseous solvent continues to move upward with the rising gas and is finally discharged through the exhaust port 160. The dried material continues to move to the discharge tank 120 for collection, and the drying of the material is completed. Among them, the solvent to be dried in the material to be dried is water or other organic solvents.

[0034] During the drying process, since the particle sizes of the materials are different and the materials also contain solvents, the materials with smaller particle sizes may block the through holes of the fluidized bed plate 140 during movement, which will reduce the amount of hot gas passing through the through holes, and the evaporation of the solvent will be slower, thereby reducing the drying efficiency of the materials. The anti-blocking component is used to clear the through holes during the drying process, which helps to ensure that the hot gas contacts the material to be dried through the through holes, thereby helping the vibrating fluidized bed to efficiently dry the material.

[0035] The anti-blocking component includes a motor 210, a crankshaft 220, a connecting sleeve 230, a connecting rod 240 and a counterweight 250. The motor 210 is used to provide power to drive the main journal 221 of the crankshaft 220 to rotate, and the connecting rod journal 222 also rotates accordingly. Since the connecting sleeve 230 is a rotating sleeve arranged on the outer periphery of the connecting rod journal 222 of the crankshaft 220, and the outer side of the connecting sleeve 230 is connected to the counterweight 250 through the connecting rod 240, the counterweight 250 has a certain weight. Therefore, when the connecting rod journal 222 rotates, the connecting sleeve 230 rotates relative to the connecting rod journal 222 under the action of the gravity of the counterweight 250 without rotating itself. The direction of the connecting rod 240 fixedly connected to the outer wall of the connecting sleeve 230 is always vertically downward. When the anti-blocking assembly is in operation, the movement trajectory of the connecting rod 240 and the counterweight 250 when rotating with the crankshaft 220 is to make a circular motion with the connecting rod journal 222 while reciprocating up and down, colliding with the fluidized bed plate 140, causing the fluidized bed plate 140 to vibrate up and down, which not only makes the materials blocked in the multiple through holes on the fluidized bed plate 140 fall off by vibration, but also helps to keep the through holes on the fluidized bed plate 140 unblocked, thereby ensuring that the hot gas passes through the through holes smoothly and contacts with the material to be dried, thereby improving the drying efficiency of the material. At the same time, when there are lumps in the material, the collision of the counterweight 250 with the fluidized bed plate 140 makes the lumped material on the fluidized bed plate 140 loose due to vibration, further improving the drying effect of the material. The axial direction of the crankshaft 220 is consistent with the length direction of the fluidized bed plate 140.

[0036] Furthermore, pressure sensors are provided at the upper and lower positions of the inner wall of the shell 1 at the fluidized bed plate 140. If the pressure values ​​of the upper and lower pressure sensors are equal or the difference is less than the preset difference, the fluidized bed plate 140 is not blocked. If the pressure difference of the upper and lower pressure sensors is greater than or equal to the preset difference, it means that the fluidized bed plate 140 is blocked. At this time, the motor 210 is started to drive the crankshaft 220 to rotate, thereby driving the connecting rod 240 and the counterweight block 250 to beat the fluidized bed plate 140, and the materials in the through holes of the fluidized bed plate 140 are beaten off to achieve the reopening of the through holes, thereby allowing the hot gas to smoothly pass through the fluidized bed plate 140 to dry the materials. This arrangement allows the motor 210 to be turned on only when the fluidized bed plate 140 is blocked, thereby achieving the effect of unblocking the fluidized bed plate 140, and avoiding the waste of electricity caused by the continuous opening of the motor 210, reducing resource waste, and saving drying costs.

[0037] The present application avoids the problem of material blocking the bed plate during the drying process through the above scheme, realizes the rapid drying of the material, and by setting the fluidized bed plate, hot air outlet and exhaust outlet, the hot gas contacts the material to be dried while taking away the solvent in the material, so as to achieve the purpose of drying the material. By setting the through holes in the drying process of the anti-blocking component for dredging, it is helpful to ensure that the hot gas contacts the material to be dried through the through holes, and then helps the vibrating fluidized bed to efficiently dry the material. When the anti-blocking component is running, the movement trajectory of the connecting rod and the counterweight block when the crankshaft rotates is to make a circular motion while reciprocating up and down, and collide with the fluidized bed plate, so that the fluidized bed plate vibrates up and down, which not only makes the materials blocked in the multiple through holes on the fluidized bed plate fall off by vibration, but also helps the through holes on the fluidized bed plate to remain unobstructed, thereby ensuring that the hot gas passes through the through holes smoothly and contacts the material to be dried, and improves the drying efficiency of the material. At the same time, when there is agglomeration in the material, the collision of the counterweight block and the fluidized bed plate makes the agglomerated material on the fluidized bed plate loose due to vibration, further improving the drying effect of the material.

[0038] like Figure 3 As shown, optionally, the connecting rod 240 and the counterweight 250 are connected via a first spring 260 .

[0039] Specifically, the connecting rod 240 drives the counterweight 250 to make a circular motion while reciprocating up and down, and collides with the fluidized bed plate, and the first spring 260 is connected between the connecting rod 240 and the counterweight 250. In this way, under long-term operation conditions, the first spring 260 can play a certain buffering role on the connection between the connecting rod 240 and the counterweight 250, thereby preventing the connection between the connecting rod 240 and the counterweight 250, and the connection between the connecting rod 240 and the connecting rod journal 222 of the crankshaft 220 from being deformed or loosened due to the long-term upward impact of the counterweight 250, which is beneficial to the long-term use of the anti-blocking component and the long-term operation of the vibrating fluidized bed.

[0040] Optionally, when any connecting rod journal 222 of the crankshaft 220 rotates to the lowest point, the counterweight 250 contacts the upper surface of the fluidized bed plate 140 .

[0041] Specifically, when any connecting rod journal 222 of the crankshaft 220 rotates to the lowest point, the counterweight 250 collides with the fluidized bed plate 140, causing the fluidized bed plate 140 to be greatly deformed, which will cause the fluidized bed plate 140 and the counterweight 250 to be subjected to impact for a long time, thus affecting their service life. This arrangement not only allows the counterweight 250 to clear the through hole of the fluidized bed plate 140, but also helps to prolong the service life of the anti-blocking assembly and the fluidized bed plate 140.

[0042] like Figure 4As shown, optionally, a plurality of spring support components are disposed at the bottom of the housing 1 , and the spring support components include a support block 310 , a second spring 320 and a base 330 .

[0043] The support block 310 is fixedly disposed at the bottom of the housing 1 . The bottom of the support block 310 is connected to one end of the second spring 320 , and the other end of the second spring 320 is connected to the base 330 .

[0044] Specifically, the base 330 is used to fix one end of the second spring 320, and the support block 310 is used to connect the second spring 320 and the bottom of the housing 1, and the support block 310 and the bottom of the housing 1 are detachably connected. When the vibration motor 130 is turned on, the housing 1 also vibrates, and the second spring 320 has a buffering effect between the housing 1 and the ground, and is conducive to the stability of the housing 1. Optionally, the outer side of the fluidized bed plate 140 is connected to the inner wall of the housing 1 by rubber.

[0045] Specifically, since the shell 1 and the fluidized bed plate 140 are always in a vibrating state, if the fluidized bed plate 140 is fixed in the shell 1 by screws or other rigid connection structures, the connection between the shell 1 and the fluidized bed plate 140 will become loose with long-term vibration, which is not conducive to the stability of the fluidized bed plate 140, and some materials may fall from the connection. Therefore, the outer side of the fluidized bed plate 140 is connected to the inner wall of the shell 1 by rubber. The rubber has a certain flexibility and can play a buffering role when the shell 1 and the fluidized bed plate 140 vibrate, which is conducive to improving the stability of the connection between the fluidized bed plate 140 and the shell 1, and is also conducive to the long-term operation of the fluidized bed plate 140.

[0046] like Figure 4 As shown, optionally, a plurality of lifting structures are evenly arranged at the bottom of the housing 1 , and the lifting structures include a hydraulic cylinder 510 and a hydraulic seat 520 .

[0047] The telescopic end of the hydraulic cylinder 510 abuts against the bottom of the housing 1 , and the end of the hydraulic cylinder 510 away from the housing 1 is connected to the hydraulic seat 520 .

[0048] Specifically, after the vibrating fluidized bed is used for a long time, the elasticity of the second spring 320 at the bottom of the shell 1 is easily reduced or loses its elasticity, resulting in a reduction in the vibration efficiency of the vibrating fluidized bed, thereby affecting the drying effect. At this time, the second spring 320 needs to be replaced, but the overall volume of the vibrating fluidized bed is large and the weight is heavy, and the second spring 320 is not easy to replace. By setting a plurality of lifting structures at the bottom of the shell 1, it is convenient to open the hydraulic cylinder 510 to extend the telescopic end of the hydraulic cylinder 510 when replacing the second spring 320, push the shell 1 up, so that the shell 1 is away from the support block 310, and replace the second spring 320. After the replacement of the second spring 320 is completed, the hydraulic cylinder 510 is started again to shrink it, so that when the shell 1 drops to abut against the support block 310, the hydraulic cylinder 510 is closed to complete the replacement of the second spring 320. This arrangement improves the degree of automation when replacing the second spring 320, which is useful for reducing the labor input of personnel.

[0049] like Figure 4 As shown, optionally, multiple exhaust ports 160 are connected to the exhaust pipe 170, and the outlet end of the exhaust pipe 170 is connected to the cyclone separator 410. The light phase of the cyclone separator 410 is connected to the dust collector 430 through the induced draft fan 420, the heavy phase outlet of the cyclone separator 410 is connected to the feed pipe 110, and the gas outlet of the dust collector 430 is connected to the atmosphere.

[0050] Specifically, after the hot gas exchanges heat with the material on the fluidized bed plate 140, the solvent in the entrained material rises to multiple exhaust ports 160 and gathers to the exhaust pipe 170 for discharge. A small amount of fine particles are also entrained in the hot gas. The hot gas entraining the particles is transported to the cyclone separator 410 through the exhaust pipe 170 for gas-solid separation. The obtained solid material is directly transported from the heavy phase outlet of the cyclone separator 410 to the feed pipe 110 and enters the shell 1 for further drying. The obtained gas enters the dust collector 430 through the suction force of the induced draft fan 420, and the gas is purified again before being discharged. This arrangement not only reduces the waste of materials, but also realizes the purification of the exhaust gas, which is conducive to the cleanliness of the surrounding environment and has good environmental protection benefits.

[0051] The technical solution of the present application is described in detail below with reference to specific embodiments.

[0052] In this embodiment, a vibrating fluidized bed is used for material drying, and the operation process during specific operation is as follows:

[0053] In this embodiment, the production of chlorantraniliprole is taken as an example to illustrate the use principle of the vibrating fluidized bed for material drying provided in the present application.

[0054] The vibration motor 130 is turned on, and the chlorantraniliprole to be dried is delivered to the fluidized bed plate 140 of the housing 1 through the feed pipe 110. The vibration motor 130 provides power to vibrate the housing 1 and the fluidized bed plate 140. The fluidized bed plate 140 tilts downward from the direction from the feed pipe 110 to the discharge tank 120, and the chlorantraniliprole to be dried containing the solvent moves toward the discharge tank 120 during the vibration process. At the same time, hot gas is delivered into the housing 1 through the hot air ports 150, and the hot gas flows from the bottom of the fluidized bed plate 140 through the multiple through holes penetrating the fluidized bed plate 140 to the top of the fluidized bed plate 140. The rising hot gas contacts the chlorantraniliprole to be dried on the fluidized bed plate 140 and performs heat exchange. As the temperature of the chlorantraniliprole to be dried rises, the temperature of the solvent mixed therein also rises and evaporates into gas, and the gaseous solvent continues to move upward with the rising hot gas and is finally discharged through the exhaust port 160. The chlorantraniliprole to be dried is gradually dried during the movement and moves to the discharge tank 120 for collection to obtain dry chlorantraniliprole.

[0055] After heat exchange, the hot gas carries the solvent in the chlorfenapyr and rises to multiple exhaust ports 160, and gathers in the exhaust pipe 170 and is discharged into the cyclone separator 410 for gas-solid separation. The solid material obtained is directly fed from the heavy phase outlet of the cyclone separator 410 to the feed pipe 110 and enters the shell 1 for further drying. The obtained gas enters the dust collector 430 through the suction force of the induced draft fan 420, and the gas is purified again before being discharged.

[0056] During the drying process, the anti-blocking assembly is turned on by timing or judging the pressure difference between the upper and lower parts of the fluidized bed plate 140, so that the materials blocked in the multiple through holes on the fluidized bed plate 140 are vibrated and fall off, thereby restoring the smooth flow of the fluidized bed plate 140. When the anti-blocking assembly is working, the motor 210 is turned on to drive the main journal 221 of the crankshaft 220 to rotate, and the connecting rod journal 222 also rotates accordingly. The movement trajectory of the connecting rod 240 and the counterweight block 250 when rotating with the crankshaft 220 is to make a circular motion while reciprocating up and down, and collide with the fluidized bed plate 140, so that the fluidized bed plate 140 vibrates up and down, so that the materials blocked in the multiple through holes on the fluidized bed plate 140 are vibrated and fall off, thereby keeping the through holes on the fluidized bed plate 140 smooth.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
