Description

Technical Field

[0001] This utility model relates to the technical field of crude salt production, and in particular to a rust treatment device at the outlet of a fluidized bed. Background Technology

[0002] During the production of crude salt, after being crushed, washed, and centrifuged, the salt is dried in a fluidized bed and then cooled in a cold air bed. During the collection and transportation of crude salt, the equipment used can introduce rust into the salt. If this rust is not removed, it will affect the quality of the crude salt. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the present invention provides a rust treatment device at the outlet of a fluidized bed that can clean rust and iron powder from raw salt.

[0004] This utility model provides a rust treatment device at the outlet of a fluidized bed, which adopts the following technical solution:

[0005] A rust treatment device at the outlet of a fluidized bed includes a box fixed to the side wall of the fluidized bed. The inlet of the box is connected to the outlet of the fluidized bed. A strong magnetic rod assembly for adsorbing iron powder and rust in raw salt is installed inside the box. The strong magnetic rod assembly includes an upper connecting plate, a lower connecting plate, and strong magnetic rods. Multiple strong magnetic rods are fixed between the upper and lower connecting plates and are evenly arranged along the length of the upper connecting plate. An installation opening is provided on the side wall of the box, and an installation plate is provided outside the installation opening. Both the upper and lower connecting plates are fixed to the installation plate, and the installation plate is detachably connected to the outer wall of the box.

[0006] Optionally, the chamber is equipped with a crushing assembly for crushing large clumps of raw salt, the crushing assembly including a connecting support plate that supports the lower connecting plate.

[0007] Optionally, the crushing assembly also includes fixed toothed plates and movable toothed plates. Multiple fixed toothed plates are fixed between the connecting support plate and the inner wall of the box. A rotating shaft is provided inside the box and is rotatably connected to the side wall of the box. Multiple movable toothed plates are evenly fixed on the rotating shaft. The movable toothed plates and fixed toothed plates are staggered. One end of the rotating shaft extends out of the box and is connected to a driving component.

[0008] Optionally, a mounting block is fixed to the bottom of the lower connecting plate, and a mounting groove for the mounting block to be inserted is provided on the top of the connecting support plate.

[0009] Compared with the prior art, the present invention has the following technical effects:

[0010] As the raw salt falls downwards into the tank, the iron powder and rust in the raw salt are attracted to the strong magnetic rod, while large clumps of raw salt are blocked by the fixed toothed plates. The staff swings the rocker arm back and forth, and under the action of the fixed and movable toothed plates, the large clumps of raw salt are broken up, thereby achieving the effect of cleaning the iron powder and rust in the raw salt and breaking up the large clumps of raw salt.

[0016] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 The present invention will be described in further detail below.

[0017] Reference Figures 1-4 This utility model discloses a rust removal device at the outlet of a fluidized bed, comprising a housing 1 fixed to the side wall of a fluidized bed 2, with the inlet of the housing 1 connected to the outlet of the fluidized bed 2. A strong magnetic rod assembly 3 is installed inside the housing 1, capable of adsorbing rust and iron powder from the raw salt.

[0018] The strong magnetic rod assembly 3 includes an upper connecting plate 31, a lower connecting plate 32, and strong magnetic rods 33. Multiple strong magnetic rods 33 are fixed between the upper connecting plate 31 and the lower connecting plate 32, and are evenly arranged along the length of the upper connecting plate 31, with gaps between adjacent strong magnetic rods 33. An installation opening is provided on the side wall of the housing 1, and an installation plate 4 is provided on the outer side of the installation opening. Both the upper connecting plate 31 and the lower connecting plate 32 are fixed to the installation plate 4, and a handle 41 is fixed to the outer side of the installation plate 4. The installation plate 4 is detachably connected to the side wall of the housing 1 by bolts. The strong magnetic rods 33 can be removed from the installation opening.

[0019] A crushing component 5 is installed at the bottom of the lower connecting plate 32. The crushing component 5 can crush large clumps of raw salt. If the large clumps of raw salt are not crushed, the raw salt will be too hard to be processed further, and cannot be screened or color sorted. The crushing component 5 includes fixed toothed plates 51. One end of the fixed toothed plates 51 is fixed to the inner wall of the box 1. Multiple fixed toothed plates 51 are evenly arranged along the length of the lower connecting plate 32. A connecting support plate 52 is fixed to the end of the fixed toothed plates 51 near the lower connecting plate 32. An installation groove 521 is opened on the side of the connecting support plate 52 near the lower connecting plate 32. An installation block 522 is fixed to the side of the lower connecting plate 32 near the connecting support plate 52. The installation block 522 is inserted into the installation groove 521 and is arranged along the length of the connecting support plate 52. A gap is provided between the side of the connecting support plate 52 away from the fixed toothed plates 51 and the inner wall of the box 1. The connecting support plate 52 provides support to the lower connecting plate 32, making the strong magnetic rod assembly 3 more stable.

[0020] The crushing assembly 5 also includes movable toothed plates 53 and a rotating shaft 54. Multiple movable toothed plates 53 are evenly fixed on the rotating shaft 54, which is rotatably connected to the side wall of the housing 1. The movable toothed plates 53 and fixed toothed plates 51 are staggered, allowing the movable toothed plates 53 to pass between adjacent fixed toothed plates 51, thereby crushing large clumps of raw salt. Large clumps of raw salt may also contain iron powder; after crushing the large clumps, the strong magnetic rod 33 can attract the magnet.

[0021] One end of the rotating shaft 54 ​​extends out of the side wall of the housing 1 and is fixed with a driving component that drives the rotating shaft 54 ​​to rotate. The driving component can be a servo motor or a rocker arm 55. The operator can periodically move the rocker arm 55 or start the servo motor to rotate the rotating shaft 54 ​​and the movable toothed plate 53, thereby crushing the raw salt. An observation hole 6 is provided on the side wall of the housing 1, and a door panel 61 is located at the position of the observation hole 6. The door panel 61 is rotatably connected to the side wall of the housing 1 and is fixed to the side wall of the housing 1 by bolts. Unscrewing the bolts allows the door panel 61 to be opened. An observation window 62 is installed on the door panel 61. Through the observation window 62, the operator can observe the condition of the raw salt inside the housing 1.

[0022] The working principle of the rust removal device at the outlet of the fluidized bed of this utility model is as follows: When the raw salt is discharged from the outlet of the fluidized bed 2, it enters the box 1. As the raw salt falls downward in the box 1, the iron powder and rust in the raw salt are attracted to the strong magnetic rod 33. Large clumps of raw salt are blocked by the fixed toothed plate 51. The operator swings the rocker arm 55 back and forth. Under the action of the fixed toothed plate 51 and the movable toothed plate 53, the large clumps of raw salt are broken up. When there is too much rust on the strong magnetic rod 33, the upper mounting plate 4 can be pulled outward to remove the strong magnetic rod 33 from the box 1. The iron powder and rust on the strong magnetic rod 33 are then cleaned. After cleaning, the strong magnetic rod 33 is put back into the box 1.

[0023] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
