Description

Technical Field

[0001] The invention relates to the technical field of dryers, and in particular to a cyclone belt dryer for molecular sieve production. Background Art

[0002] Molecular sieve is a synthetic hydrated aluminosilicate or natural zeolite with the function of screening molecules. It has many channels with uniform pore sizes and neatly arranged holes in its structure. Molecular sieves of different pore sizes separate molecules of different sizes and shapes. It has the advantages of high adsorption capacity, strong selectivity and high temperature resistance. It is widely used in organic chemical industry and petrochemical industry. Molecular sieves are usually produced in spherical or strip shapes. Different types of molecular sieves are used according to different needs.

[0003] The patent with publication number: CN113137849A discloses a molecular sieve forming and drying mechanism, including a box body, a fixed plate fixedly installed in the box body, the fixed plate divides the inner part of the box body into a first cavity and a second cavity, a first conveyor belt is installed in the first cavity, a second conveyor belt is installed in the second cavity, a through groove is opened in the fixed plate, and an inclined plate is installed at the bottom of the through groove.

[0004] There are still some deficiencies in the actual use of molecular sieve drying in the prior art: 1. Molecular sieve particles are generally dried using a conveyor belt. When the molecular sieve particles are piled together on the surface of the conveyor belt, the heat cannot contact the inside of the molecular sieve particles, resulting in uneven drying; 2. Even if only one layer of molecular sieve is laid on the conveyor belt for drying, the drying effect of the surface of the molecular sieve in contact with the conveyor belt is not as good as that in contact with the heat, and the heating is uneven, so that the drying time of the molecular sieve needs to be extended to completely remove the moisture.

The fixed frame 14 is fixedly connected to the first conveyor belt 7, the two limit frames 15 are symmetrically distributed, the two limit frames 15 are both slidably connected to the fixed frame 14, the outer walls on both sides of the strip groove 17 are slidably connected to the two limit frames 15, the four limit blocks 26 are slidably connected to the outer walls of the strip groove 17, every two limit blocks 26 are fixedly connected to the same limit frame 15, the two connecting blocks 31 are fixedly connected to the two sides of the strip groove 17, the two sliding shafts 29 are fixedly connected to the two connecting blocks 31, and the ends of the two sliding shafts 29 away from the strip groove 17 are slidably connected to the inner wall of the drying machine frame 1 through the telescopic control groove 20.

[0041] In this embodiment, the molecular sieve particles fall on the strip groove 17. If they are parallel to the strip groove 17, they will fall into the strip groove 17. If they are not parallel to the strip groove 17, when the first gear 10 continues to move and meshes with the first rack 22, the first gear 10 drives the second bevel gear 13 to rotate, and the second bevel gear 13 drives the sprocket wheel assembly 28 to rotate through the first bevel gear 40 and the third gear 39, so that the sprocket wheel assembly 28 drives the cam 38 to rotate through the transmission shaft cylinder 27, and the cam 38 continuously resists the limit frame 15, so that the limit frame 15 starts to swing back and forth, so that the molecular sieve particles continuously adjust their direction until they are parallel to the strip groove 17 and fall into the strip groove 17, so that all the molecular sieve particles are convenient for subsequent drying. It can rotate by itself, heat evenly and save time. When the fixed frame 14 moves to the end of the telescopic control groove 20 close to the feed box 6, the shape of the telescopic control groove 20 changes at this time, so that the sliding shaft 29 drives the strip groove 17 to gradually retract into the limiting frame 15 through the connecting block 31, so that the closing plate 16 is limited by the limiting frame 15 and thus closed, to prevent the molecular sieve particles from falling out when the strip groove 17 is flipped from top to bottom, and then when the opening of the strip groove 17 faces downward and continues to move in the direction of the lower material slide plate 5, when the sliding shaft 29 slides to the raised part of the telescopic control groove 20, the strip groove 17 is extended to place the molecular sieve particles on the drying conveyor belt 8, and then the strip groove 17 is retracted again.

[0042] Among them, the rotation mechanism 202 includes a third rack 24, a second gear 30, a multi-section telescopic rod 33, a first limit shaft 19 and a reset shaft 36. The second gear 30 is rotatably connected to the connecting block 1 31, the first limit shaft 19 is fixedly connected to the two limit frames 15, the third rack 24 is fixedly connected to the connecting block 1 31, the multi-section telescopic rod 33 is fixedly connected to the second gear 30, and two rotation mechanisms 202 are provided. The two rotation mechanisms 202 are symmetrically distributed, and the two multi-section telescopic rods 33 are fixedly connected to the same mounting plate 2 34, the inner wall of one of the limit frames 15 is rotatably connected to the reset shaft 36, and the two ends of the reset shaft 36 are fixedly connected to spring rolls, and a number of rubber ropes 35 are fixedly connected between the mounting plate 2 34 and the reset shaft 36.

[0043] Among them, there are several direction adjustment mechanisms 303, and the several direction adjustment mechanisms 303 are all installed on the outer wall of the first conveyor belt 7. A support plate 12 is arranged inside the first conveyor belt 7, and the outer walls on both sides of the support plate 12 are fixedly connected to the drying machine frame 1.

[0044] In this embodiment, when the strip groove 17 is retracted to half, the third rack 24 will drive the second gear 30 to rotate, so that the multi-section telescopic rod 33 drives the mounting plate 2 34 to move to the side of another limiting frame 15, thereby pulling out the rubber rope 35. Since the rubber rope 35 itself has a certain elasticity and is in a pulled state at this time, the rubber rope 35 will contact the outer surface of the strip molecular sieve particles, thereby assisting in flattening the molecular sieve particles. The gap between the rubber rope 35 and the drying conveyor belt 8 can only have one layer of molecular sieve particles, so that when the first gear 10 is meshed with the second rack 23 again, the entire limiting frame 15 moves back and forth so that the rubber rope 35 can separate and flatten the partially stacked molecular sieve particles, driving the molecular sieve particles to rotate, so that the heat can be evenly distributed during drying, saving drying time.

[0045] The specific working principle and method of use of the present invention are explained in detail below: when in use, the molecular sieve is placed in the feed box 6, and the third motor 4 is set to rotate intermittently by ninety degrees. The rotation of the first motor 2 and the second motor 3 can make the drying conveyor belt 8 and the support plate 12 move synchronously toward the unloading slide plate 5.

[0046] When the first conveyor belt 7 moves to the bottom of the feed box 6, the third motor 4 rotates to transport the molecular sieve particles in the unloading column 18, and the molecular sieve particles fall on the strip groove 17. If they are parallel to the strip groove 17, they will fall into the strip groove 17. If they are not parallel to the strip groove 17, when the first gear 10 continues to move and engages with the first rack 22, the first gear 10 drives the second bevel gear 13 to rotate, and the second bevel gear 13 drives the sprocket wheel assembly 28 to rotate through the first bevel gear 40 and the third gear 39, so that the sprocket wheel assembly 28 drives the cam 38 to rotate through the transmission shaft tube 27, and the cam 38 continuously resists the limit frame 15, so that the limit frame 15 starts to swing back and forth, so that the molecular sieve particles continuously adjust their direction until they are parallel to the strip groove 17 and fall into the strip groove 17, so that all the molecular sieve particles can rotate by themselves when they are dried later, and the heating is evenly distributed, saving time.

[0047] When the fixed frame 14 moves to the end of the telescopic control groove 20 close to the feed box 6, the shape of the telescopic control groove 20 changes at this time, so that the sliding shaft 29 drives the strip groove 17 to gradually retract into the limiting frame 15 through the connecting block 131, so that the closing plate 16 is limited by the limiting frame 15 and thus closed, to prevent the molecular sieve particles from falling out when the strip groove 17 is flipped from top to bottom, and then when the opening of the strip groove 17 faces downward and continues to move in the direction of the lower material slide plate 5, when the sliding shaft 29 slides to the raised part of the telescopic control groove 20, the strip groove 17 is extended, and the molecular sieve particles are placed on the drying conveyor belt 8, and then the strip groove 17 is retracted again.

[0048] When the strip groove 17 is retracted to half, the third rack 24 will drive the second gear 30 to rotate, so that the multi-section telescopic rod 33 drives the mounting plate 2 34 to move to the side of another limiting frame 15, thereby pulling out the rubber rope 35. Since the rubber rope 35 itself has a certain elasticity and is in a pulled state at this time, the rubber rope 35 will contact the outer surface of the strip molecular sieve particles, thereby assisting in flattening the molecular sieve particles. The gap between the rubber rope 35 and the drying conveyor belt 8 can only have one layer of molecular sieve particles, so that when the first gear 10 is meshed with the second rack 23 again, the entire limiting frame 15 reciprocates so that the rubber rope 35 can separate and flatten the partially stacked molecular sieve particles, driving the molecular sieve particles to rotate, so that the heat can be evenly distributed during drying, saving drying time.

[0049] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0050] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
