Description

Technical Field

[0001] This utility model relates to the technical field of granular salt drying, and in particular to a fluidized bed with adjustable air pressure. Background Technology

[0002] In the production of crude salt, it needs to be dried using a fluidized bed. The existing fluidized bed chamber is 1.2 meters wide, and during operation, the air volume is 9000 m³ / h and the air pressure is 3.8 kPa. This configuration is suitable for drying crude salt with many small particles. When the crusher is not turned on and there are many large particles of crude salt, the drying effect of the fluidized bed is poor and it cannot meet the drying requirements of large particles of salt. Utility Model Content

[0003] This utility model provides a fluidized bed with adjustable air pressure, which facilitates the control of air pressure in the fluidized bed, thereby improving the drying speed of large-particle salt.

[0004] A fluidized bed with adjustable air pressure, employing the following technical solution:

[0005] An adjustable-pressure fluidized bed includes a fluidized bed body with a partition inside. Two silicone plates are disposed below the partition and hinged to the inner wall of the fluidized bed body. The partition has multiple sets of vertical and oblique air holes. A drive assembly is installed on the inner wall of the fluidized bed body to drive the two silicone plates to be in a horizontal or vertical state. When the silicone plates are in a horizontal state, they are pressed against the bottom of the partition and the vertical and oblique air holes are closed. When the silicone plates are in a vertical state, they are pressed against the inner wall of the fluidized bed body.

[0006] Furthermore, the drive assembly includes a drive cylinder, a first connecting rod, and a second connecting rod. The drive cylinder is fixed to the inner wall of the boiling bed body. A connecting shaft is fixed on the piston rod of the drive cylinder. One end of the first connecting rod is hinged to one of the silicone plates, and one end of the second connecting rod is hinged to the other silicone plate. The ends of the first and second connecting rods away from the silicone plates are both hinged to the connecting shaft.

[0007] Furthermore, a groove is provided on the inner wall of the boiling bed body, and one end of the connecting shaft is inserted into the groove and slidably connected to it.

[0008] Compared with the prior art, the present invention has the following technical effects:

[0009] When producing small-particle salt, the drive cylinder retracts, and the silica gel plate is in the open state, which does not affect the ventilation area. When producing large-particle salt, the drive cylinder extends, driving the first and second connecting rods to close the silica gel plate, blocking part of the vertical and oblique air holes, increasing the air pressure, so that the large-particle salt boils in the fluidized bed furnace and accelerates drying.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0019] Reference Figures 1-6 An adjustable-pressure fluidized bed includes a fluidized bed body 1, a partition 2 fixed to the inner wall of the fluidized bed body 1, a feed inlet 11 on the side wall of the fluidized bed body 1, a feed ejector 3 installed at the feed inlet 11 on the outer wall of the fluidized bed body 1, and a discharge outlet 12 on the side of the fluidized bed body 1 away from the feed ejector 3. A hopper elevator is installed at the discharge outlet 12. Both the feed inlet 11 and the discharge outlet 12 are higher than the height of the partition 2. Multiple air inlets 13 are opened at the bottom of the fluidized bed body 1, and multiple air outlets 14 are opened at the top of the fluidized bed body 1.

[0020] The partition 2 has multiple sets of vertical air blowing holes 21 and multiple sets of oblique air blowing holes 22, arranged sequentially. The air blown out by the oblique air blowing holes can blow the salt particles towards the air outlet 14. One set of vertical air blowing holes 21 is arranged along the width direction of the partition 2, and one set of oblique air blowing holes 22 is also arranged along the width direction of the partition 2. Two silicone plates 4 are arranged below the partition 2, along the length direction of the partition 2. The silicone plates 4 are hinged to the inner wall of the fluidized bed body 1. A drive assembly 5 is provided on the inner wall of the fluidized bed body 1 to drive the two silicone plates 4 to be placed horizontally or vertically.

[0021] When producing small-particle salt, the silica gel plate 4 is in a vertical position, which is the open state and does not affect the ventilation area. When the silica gel plate 4 is placed horizontally, it is in the closed state, with its bottom fitting against the bottom of the partition 2. This seals some of the vertical air holes 21 and some of the oblique air holes 22, increasing the air pressure and enabling large-particle salt to boil in the fluidized bed body 1, thereby increasing the drying speed of the large-particle salt.

[0022] The drive assembly 5 includes a drive cylinder 51, a first connecting rod 52, and a second connecting rod 53. One end of the first connecting rod 52 is hinged to one of the silicone plates 4, and one end of the second connecting rod 53 is hinged to the other silicone plate 4. A sliding groove 15 is provided on the inner wall of the boiling bed body 1, and a connecting shaft 54 ​​is slidably connected in the sliding groove 15. The ends of the first connecting rod 52 and the second connecting rod 53 away from the silicone plate 4 are both hinged to the connecting shaft 54. The drive cylinder 51 is fixed on the inner wall of the boiling bed body 1, and the piston rod of the drive cylinder 51 is fixed to the connecting shaft 54.

[0023] The implementation principle of the fluidized bed with adjustable air pressure of this utility model is as follows: When it is necessary to dry large particles of salt, the driving cylinder 51 drives the first connecting rod 52 and the second connecting rod 53 to move upward, thereby driving the silica gel plate 4 from a vertical state to a horizontal state, closing some of the vertical air holes 21 and the oblique air holes 22, increasing the air pressure, and causing the large particles of salt to boil in the fluidized bed body 1, thereby increasing the drying speed of the large particles of salt.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model are included within the scope of protection of the present utility model.
