Description

Technical Field

[0001] The utility model belongs to the technical field of chemical processing, and specifically relates to an aluminum fluoride production device. Background Art

[0002] Aluminum fluoride, with the molecular formula of AlF3, is a colorless triclinic white powder. Anhydrous aluminum fluoride is a large hexagonal hexahedral crystal, which is an ionic crystal. The production and preparation of aluminum fluoride can be roughly divided into two categories: dry process and wet process. The dry process uses hydrogen fluoride gas that has been simply dusted and deacidified to react with aluminum hydroxide, and then mixes it with dry aluminum hydroxide, sends it into a fluidized bed reactor to mix with a catalyst, and separates the gas phase from the solid particles during the fluid movement, and finally obtains the aluminum fluoride product.

[0003] In the prior art, when aluminum fluoride is separated by air drum using a fluidized bed reactor, due to the uneven flow velocity on the flow section, a part of the material near the edge flows in the opposite direction and becomes a backflow, causing particle remixing. A common solution is to add a partition inside the fluidized bed reactor to prevent the particles from flowing back during movement. The long-term collision between the particles and the partition will cause the partition to wear and become dirty. However, the partition is installed inside the fluidized bed reactor, and it is extremely inconvenient to disassemble and replace. Utility Model Content

It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0025] like Figure 1-5 As shown, an aluminum fluoride production device includes a fluidized bed reactor 1, a splicing plate 2, an L-shaped plate 205 and a partition 3. The fluidized bed reactor 1 is set to be a plurality of fluidized bed reactors 1, and two fluidized bed reactors 1 are fixedly connected by a connecting block 101. The splicing plates 2 are set to be a plurality of groups, and a group is two symmetrical ones. The splicing plates 2 are detachably assembled between the two fluidized bed reactors 1. A movable groove 102 is opened through the middle of the connecting block 101, and a screw 103 is threadedly connected to the middle of the movable groove 102. The screw 103 One end of the splicing plate 2 is rotatably connected with an inlay plate 104 located inside the movable groove 102, the splicing plate 2 is movably engaged with the connecting block 101, both ends of the splicing plate 2 are fixedly connected with engaging blocks 207, a slot 208 for inserting and engaging the inlay plate 104 is provided between the splicing plate 2 and the engaging block 207, an embedding column 203 is fixedly connected to one side of the splicing plate 2, the partition plate 3 is movably inserted between the two L-shaped plates 205, and the outer wall of the partition plate 3 is provided with an embedding groove 302 for the embedding column 203 to be embedded and engaged.

[0026] According to the above structure, the connecting block 101 connects several fluidized bed reactors 1 into one, slides the partition 3 between the two L-shaped plates 205, and makes the embedding groove 302 engage with the embedding column 203 to fix the position of the partition 3, and inserts the two splicing plates 2 between the two fluidized bed reactors 1 opposite to each other. When the two embedding blocks 207 are fitted, the insert plate 104 is pushed to move in the movable groove 102 by rotating the screw 103, so that the insert plate 104 is fitted with the two embedding blocks 207, and at the same time, the insert plate 104 is inserted into the slot 208 to fix the two splicing plates 2.

[0027] See attached Figure 3-7 The L-shaped plate 205 is symmetrically fixedly assembled on one side of the splicing plate 2. The two sides of the splicing plate 2 and the two sides of the L-shaped plate 205 are symmetrically slidably provided with sealing rings 201. One side of the L-shaped plate 205 is provided with a through-type embedding groove 206 for the sealing ring 201 to slide and fit. The bottom of the sealing ring 201 is symmetrically fixedly connected with a sliding block 204. One side of the splicing plate 2 is provided with a sliding groove 202 for the sliding block 204 to slide in an array. One end of the two sliding blocks 204 and located inside the splicing plate 2 are connected together. A connecting rod 210 is fixedly connected to the two connecting rods 210, and a spring column 211 is elastically connected between the two connecting rods 210. A rack 212 is fixedly connected to one side of the two connecting rods 210. The two racks 212 are arranged in a mirror-symmetrical manner. The outer wall of the splicing plate 2 is rotatably connected to a rotating handle 209. One end of the rotating handle 209 is fixedly connected to the inside of the splicing plate 2 with a gear 213. The gear 213 is meshed with the two racks 212 at the same time. The partition 3 has symmetrical grooves 301 on both sides for the sealing ring 201 to slide and fit.

[0028] According to the above structure, when the splicing plate 2 is inserted between the two fluidized bed reactors 1, the rotating handle 209 is rotated to drive the gear 213 to rotate, and the gear 213 drives the two racks 212 to move toward each other. The racks 212 will pull the connecting rod 210 and shrink the spring column 211. The movement of the connecting rod 210 drives the sliding block 204 to slide on the inner wall of the sliding groove 202. The sliding block 204 drives the sealing ring 201 to move, and pulls the sealing ring 201 to fit the L-shaped plate 205. The sealing ring 201 is embedded in the embedding groove 1 206, and the embedding groove 2 301 makes room for the sealing ring 201 to move downward. The above steps shrink the sealing ring 201 to The interior of the splicing plate 2 can make the splicing plate 2 smoothly inserted into the fluidized bed reactor 1 without being hindered by the sealing ring 201. After loosening the rotating handle 209, the elastic force of the spring column 211 causes the connecting rod 210 to rebound, thereby popping out the sealing ring 201 to fit the inner wall of the fluidized bed reactor 1, thereby enhancing the airtightness of the splicing plate 2; the utility model can timely disassemble, replace and maintain the partition 3 by arranging the flexibly detachable splicing plate 2 and partition 3 on the fluidized bed reactor 1, thereby avoiding the anti-backmixing effect being affected by the worn and dirty partition 3, and the structure is simple and easy to operate, taking into account the airtightness of the fluidized bed reactor 1.

[0029] The working principle of the utility model is as follows: the connecting block 101 connects several fluidized bed reactors 1 into one, the partition 3 is slidably inserted between the two L-shaped plates 205, so that the embedding groove 302 is embedded with the embedding column 203, the position of the partition 3 is fixed, and the two splicing plates 2 are inserted into the two fluidized bed reactors 1 oppositely. When the two embedding blocks 207 are fitted, the insert plate 104 is pushed to move in the movable groove 102 by rotating the screw 103, so that the insert plate 104 is fitted with the two embedding blocks 207, and the insert plate 104 is inserted into the slot 208 to fix the two splicing plates 2; when the splicing plate 2 is inserted between the two fluidized bed reactors 1, the rotating handle 209 is rotated to drive the gear 213 to rotate, and the gear 213 drives the two racks 212 to move oppositely, and the racks 2 12 will pull the connecting rod 210 and shrink the spring column 211. The movement of the connecting rod 210 drives the sliding block 204 to slide on the inner wall of the sliding groove 202. The sliding block 204 drives the sealing ring 201 to move, and pulls the sealing ring 201 to fit the L-shaped plate 205. The sealing ring 201 is embedded in the embedding groove 1 206, and the embedding groove 2 301 makes room for the sealing ring 201 to move downward. The above steps shrink the sealing ring 201 to the inside of the splicing plate 2, so that the splicing plate 2 can be smoothly inserted into the fluidized bed reactor 1 without being hindered by the sealing ring 201. After the rotating handle 209 is released, the elastic force of the spring column 211 causes the connecting rod 210 to rebound, thereby popping out the sealing ring 201 to fit the inner wall of the fluidized bed reactor 1, thereby enhancing the airtightness of the splicing plate 2.

[0030] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
