Description

Technical Field

[0001] The utility model relates to the technical field of distillation column feeding, in particular to a circulating feeding device for a distillation column. Background Technique

[0002] Distillation columns are widely used in the fields of chemical industry, petrochemical industry, metallurgy, light industry, textile, soda making, pharmaceutical, pesticide, electroplating, electronics, etc. During the working process of the distillation column, the main function of the distillation column is for purification effect. In the existing distillation column during the working process, the feeding mechanism cannot achieve circulating feeding, resulting in the phenomenon of material shortage in the distillation column, and the distillation operation cannot be carried out in a timely and efficient manner. Eventually, the purification effect is not obvious and the purification efficiency is not high. Therefore, a circulating feeding device for a distillation column is designed and produced here to solve the above problems. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a circulating feeding device for a distillation column to solve the problems raised in the above background technique.

[0004] To solve the above technical problems, the utility model provides the following technical solution: A circulating feeding device for a distillation column includes a distillation box that can be placed inside the distillation column and two storage mechanisms. Distillation holes are opened on both the left and right side walls of the distillation box. The distillation box is placed inside the distillation column, and the distillation column provides the stability required for distillation. The raw materials falling in the distillation box are distilled through the distillation holes.

[0005] The two storage mechanisms are fixedly arranged at the upper and lower ends of the distillation box. Both storage mechanisms are used for temporarily storing raw materials. They alternately change positions up and down with the distillation box as the center, and can circularly convey the raw materials in the two storage mechanisms, which can improve the distillation efficiency.

[0006] The storage mechanism includes a storage box. The two storage boxes are respectively fixed at the upper and lower ends of the distillation box, and a material guiding hole is opened between the storage box and the distillation box. An inlet is opened at one end of the storage box away from the distillation box, and a feed pipe is arranged at the opening of the inlet. The pipe orifice of the feed pipe is connected with a sealing cover through internal threads. The raw materials to be distilled are introduced into the storage box of one of the storage mechanisms, and the sealing cover is covered. The raw materials enter the distillation box through the material guiding hole. During the process of the raw materials falling, the raw materials are distilled through the distillation holes. When the raw materials completely fall and enter the other storage box through the other material guiding hole, then they rotate around the transmission rod to swap the upper and lower positions of the two storage boxes. The lower storage box is adjusted to the upper position, and the raw materials continue to fall for distillation operation again, realizing circulating feeding and meeting the distillation requirements.

[0007] Transmission rods are fixedly arranged on both the front and rear side walls of the distillation box. The distillation box is rotationally connected with the inner side wall of the distillation column through the transmission rods. The distillation box rotates around the transmission rods, causing the two storage boxes to alternately change positions up and down.

[0008] In a further embodiment, a rolling mechanism is provided inside the distillation box. The raw materials enter the distillation box through the material guiding holes, pass through the rolling mechanism, and are rolled and crushed by the rolling mechanism, which can improve the distillation efficiency.

[0009] The rolling mechanism includes a number of rolling shafts and a driving motor. Two rolling shafts form a group and are horizontally distributed left and right. There is a rolling gap between the two rolling shafts in the same group. One end of the rolling shaft is rotatably connected to one end of the inner wall of the distillation box, and the other end of the rolling shaft is connected with a gear disk. Adjacent groups of rolling shafts are distributed up and down, and the gear disks of the two rolling shafts facing each other up and down are meshed together. The driving motor is fixedly connected to the end of one transmission rod, and the power shaft of the driving motor rotates and extends into the distillation box and is connected to the side wall of the end of one gear disk. The driving motor provides power to drive one gear disk to rotate, and this gear disk can drive the adjacent gear disk to transmit. By the same token, adjacent two gear disks are meshed together, and all gear disks can be rotated. All rolling shafts can rotate inside the distillation box. The rotation of the rolling shafts in the same group can roll the raw materials in the rolling gap to avoid large particle raw materials, resulting in low distillation efficiency.

[0010] In a further embodiment, a number of material stirring rods are fixedly arranged on the outer wall of the rolling shaft. The material stirring rods of adjacent two rolling shafts are staggeredly distributed. The material stirring rods can rotate synchronously with the rolling shafts. As long as the raw materials passing through the feeding gap will be scattered by the material stirring rods, avoiding the phenomenon of caking and affecting the distillation efficiency.

[0011] In a further embodiment, a weight mechanism is provided at the end of one transmission rod far from the driving motor, so that during the distillation process of the distillation box, it will not randomly flip around the transmission rod, resulting in the random alternation of the positions of the upper and lower two storage boxes and affecting the efficiency of cyclic feeding.

[0012] The weight mechanism includes a connecting disk. The connecting disk is fixedly arranged at the end of one transmission rod far from the driving motor. A through hole is opened on the radial side wall of the connecting disk. A guiding rod is slidably inserted into the through hole. Counterweight blocks are fixedly arranged at both ends of the guiding rod. When the two storage boxes are distributed up and down, the guiding rod slides down in real time along the through hole of the connecting disk, so that one of the upper counterweight blocks fits against the side wall of the connecting disk, while the other counterweight block is far from the connecting disk, playing a role of counterweight to prevent the distillation box from randomly flipping around the transmission rod.

[0013] In a further embodiment, the weight mechanism further includes a limiting ejector rod. The bottom end of the limiting ejector rod is fixedly connected with a connecting base fixedly connected to the outer wall of the distillation tower. A plugging groove for inserting the limiting ejector rod is opened at one end of the counterweight block far from the guiding rod. After the lower counterweight block is far from the connecting disk, it can be directly limited by inserting the plugging groove into the limiting ejector rod, thereby ensuring that the distillation box will not randomly flip.

[0014] In a further embodiment, the material guiding hole between the material storage box and the distillation box is in a frustum shape. The purpose of this setting is to avoid the situation where the raw materials remaining inside the upper material storage box cannot be completely discharged during the feeding process.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] The present utility model is a distillation tower circulating feeding device. The raw materials to be distilled are introduced into the material storage box of one of the material storage mechanisms, and the sealing cover is covered. The raw materials enter the distillation box through the material guiding hole, pass through the rolling mechanism, and the raw materials are rolled and crushed by the rolling mechanism, which can improve the distillation efficiency. During the feeding process, the raw materials are distilled through the distillation holes. When the raw materials completely fall and enter another material storage box through another material guiding hole, they then rotate around the transmission rod to swap the upper and lower positions of the two material storage boxes. The lower material storage box is adjusted to the upper position, and the raw materials continue to fall and are distilled again to achieve circulating feeding and meet the distillation requirements.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4 In this embodiment, a distillation box 1 and two storage mechanisms 2 that can be placed inside a distillation tower are provided. Distillation holes 11 are formed in the left and right side walls of the distillation box 1. The distillation box 1 is placed inside the distillation tower, and the distillation tower provides the stability required for distillation. The raw materials falling in the distillation box 1 are distilled through the distillation holes 11.

[0025] The two storage mechanisms 2 are fixedly arranged at the upper and lower ends of the distillation box 1. The two storage mechanisms 2 are both used for temporarily storing raw materials. Taking the distillation box 1 as the center, they alternately change positions up and down, and the raw materials in the two storage mechanisms 2 can be circulated and conveyed, which can improve the distillation efficiency.

[0026] Driving rods 12 are fixedly arranged on the front and rear side walls of the distillation box 1. The distillation box 1 is rotationally connected to the inner side wall of the distillation tower through the driving rods 12. The distillation box 1 rotates around the driving rods 12, so that the two storage boxes 21 alternately change positions up and down.

[0027] The storage mechanism 2 includes a storage box 21. The two storage boxes 21 are respectively fixed at the upper and lower ends of the distillation box 1. A material guiding hole is formed between the storage box 21 and the distillation box 1. An inlet opening is formed at one end of the storage box 21 away from the distillation box 1, and a feeding pipe 22 is arranged at the inlet opening. The pipe orifice of the feeding pipe 22 is connected with a sealing cover 23 through internal threads. The raw materials to be distilled are introduced into the storage box 21 of one of the storage mechanisms 2, and the sealing cover 23 is covered. The raw materials enter the distillation box 1 through the material guiding hole. During the process of the raw materials falling, the raw materials are distilled through the distillation holes 11. When the raw materials completely fall and enter another storage box 21 through another material guiding hole, then it rotates around the driving rod 12 to change the positions of the two storage boxes 21 up and down. The lower storage box 21 is adjusted to the upper position, and the raw materials continue to fall, and the distillation operation is carried out again, realizing cyclic feeding and meeting the distillation requirements.

[0028] A rolling mechanism 3 is arranged inside the distillation box 1. The raw materials enter the distillation box 1 through the material guiding hole, pass through the rolling mechanism 3, and the raw materials are rolled and crushed by the rolling mechanism 3, which can improve the distillation efficiency.

[0029] The rolling mechanism 3 includes a plurality of roller shafts 31 and a driving motor 33. Two roller shafts 31 are in a group and are horizontally distributed left and right. A roller gap is arranged between the two roller shafts 31 in the same group, and the roller gap is used for the raw materials to fall.

[0030] One end of the roller material shaft 31 is rotatably connected to one end of the inner wall of the distillation box 1. The other end of the roller material shaft 31 is connected with a gear disk 32. Two adjacent groups of roller material shafts 31 are distributed up and down, and the gear disks 32 of the two roller material shafts 31 that are opposite up and down are engaged with each other. The driving motor 33 is fixedly connected to the end of one of the transmission rods 12, and the power shaft of the driving motor 33 rotates and extends into the distillation box 1 and is connected to the side wall of the end of one of the gear disks 32. The driving motor 33 provides power to drive one of the gear disks 32 to rotate, and this gear disk 32 can drive the adjacent gear disks 32 to transmit. By the same token, two adjacent gear disks 32 are engaged with each other, enabling all the gear disks 32 to rotate. All the roller material shafts 31 can rotate inside the distillation box 1. The rotation of the roller material shafts 31 in the same group can roll and press the raw materials in the roller gap, preventing large-particle raw materials from occurring and resulting in low distillation efficiency.

[0031] Embodiment 2

[0032] Please refer to Figures 1-4 , and further improvements are made on the basis of Embodiment 1:

[0033] A weight mechanism 4 is provided at the end of one of the transmission rods 12 away from the driving motor 33. By setting the weight mechanism 4, during the distillation process of the distillation box 1, it will not randomly flip around the transmission rod 12, causing the positions of the upper and lower two storage boxes 21 to be randomly alternated, affecting the efficiency of cyclic feeding.

[0034] The weight mechanism 4 includes a connection disk 41. The connection disk 41 is fixedly arranged at the end of one of the transmission rods 12 away from the driving motor 33. A through hole is formed in the radial side wall of the connection disk 41. A guide rod 42 is slidably inserted into the through hole. Weight blocks 43 are fixedly arranged at both ends of the guide rod 42. When the two storage boxes 21 are distributed up and down, the guide rod 42 slides down in real time along the through hole of the connection disk 41, so that one of the upper weight blocks 43 fits against the side wall of the connection disk 41, while the other weight block 43 is away from the connection disk 41, playing a role in counterweight and preventing the distillation box 1 from randomly flipping around the transmission rod 12.

[0035] The weight mechanism 4 further includes a limit ejector rod 45. The bottom end of the limit ejector rod 45 is fixedly connected to a connection base 46 fixedly connected to the outer wall of the distillation tower. A plug-in groove 44 for inserting the limit ejector rod 45 is formed at one end of the weight block 43 away from the guide rod 42. After the lower weight block 43 is away from the connection disk 41, by inserting the plug-in groove 44 into the limit ejector rod 45, the position of the weight mechanism 4 can be directly limited, thereby ensuring that the distillation box 1 will not randomly flip.

[0036] The material guide hole between the storage box 21 and the distillation box 1 is of a frustum-shaped structure. The purpose of this setting is to prevent raw materials from remaining inside during the feeding process of the upper storage box 21 and being unable to be completely discharged.

[0037] A plurality of material shifting rods 34 are fixedly arranged on the outer wall of the roller material shaft 31. The material shifting rods 34 can rotate synchronously with the roller material shaft 31. The material shifting rods 34 of adjacent two roller material shafts 31 are distributed in a staggered manner. As long as the raw materials passing through the blanking gap will be scattered by the material shifting rods 34, avoiding the phenomenon of caking and affecting the distillation efficiency.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
