A wet digester for calcium hydroxide equipped with a foam suppression device

Abstract

This utility model discloses a wet digester for calcium hydroxide with a foam suppression device, including a digestion chamber. Support legs are fixedly installed at the bottom of the digestion chamber. An internal dispersing mechanism is provided within the digestion chamber, comprising a mounting frame, a second motor, a second rotating shaft, a fixed plate, a mounting column, and a strip plate. The mounting frame is slidably connected to both sides of the digestion chamber. A second motor is fixedly installed on the top of the mounting frame. A second rotating shaft, which is inserted and connected to the mounting frame, is fixedly installed on the output shaft of the second motor. A fixed plate is fixedly installed at the bottom of the second rotating shaft, and a mounting column is fixedly installed at the bottom of the fixed plate. By starting the second motor, the second rotating shaft rotates, which in turn rotates the fixed plate and the mounting column, causing the strip plate to rotate. This disperses the foam inside the digestion chamber onto the inner wall and breaks up the foam, thereby dispersing the foam and improving the quality of the produced calcium hydroxide.

[0015] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0016] like Figures 1-3 As shown, an embodiment of this utility model proposes a calcium hydroxide wet digester with a foam suppression device, including a digestion tank 1, and a support leg 15 fixedly installed at the bottom of the digestion tank 1; The digester 1 is equipped with a dispersing mechanism, which includes a mounting frame 11, a second motor 10, a second rotating shaft 9, a fixed plate 8, a mounting column 7, and a strip plate 6. The mounting frame 11 is slidably connected to both sides of the digester 1. The second motor 10 is fixedly mounted on the top of the mounting frame 11. The output shaft of the second motor 10 is fixedly mounted with the second rotating shaft 9, which is inserted and connected to the mounting frame 11. The fixed plate 8 is fixedly mounted on the bottom end of the second rotating shaft 9. The mounting column 7 is fixedly mounted on the bottom of the fixed plate 8. The strip plate 6 is fixedly mounted on the outer ring of the mounting column 7.

[0017] Specifically, a first motor 2 is fixedly installed on one side of the digester 1, and a first rotating shaft 3 is fixedly installed on the output shaft of the first motor 2. The first rotating shaft 3 passes through and extends into the digester 1. The first motor 2 drives the first rotating shaft 3 to rotate, and the first rotating shaft 3 drives the fixed roller 4 to rotate.

[0018] Specifically, a fixed roller 4 is fixedly installed at one end of the first rotating shaft 3 inside the digester 1. Multiple stirring plates 5 are fixedly installed on the outer ring of the fixed roller 4. The rotation of the fixed roller 4 drives the stirring plates 5 to rotate and stirs the material in the digester 1.

[0019] Specifically, the digester 1 has mounting grooves 12 on both sides of its inner wall. The inner walls of the two mounting grooves 12 are slidably connected to connecting blocks 13. The connecting blocks 13 are slidably connected to the mounting frame 11 through the mounting grooves 12. The connecting blocks 13 fix the mounting frame 11 and limit the movement of the mounting frame 11.

[0020] Specifically, the two connecting blocks 13 are fixedly connected to the mounting bracket 11 on the side that is far apart from each other, and the second motor 10 is fixed by the mounting bracket 11.

[0021] Specifically, an electric cylinder 14 is fixedly installed on one side of the inner wall of one of the mounting slots 12. The output shaft of the electric cylinder 14 is fixedly connected to the corresponding connecting block 13. The electric cylinder 14 drives the connecting block 13 to move, and drives the mounting bracket 11 to move.

[0022] Working principle: During production, the first motor 2 is started to drive the first rotating shaft 3 to rotate, which in turn drives the fixed roller 4 to rotate, and also drives the stirring plate 5 to rotate, thus stirring the calcium hydroxide slurry produced in the digestion tank 1. During the stirring process, foam may be generated. At this time, the second motor 10 is started to drive the second rotating shaft 9 to rotate, which in turn drives the fixed plate 8 to rotate. This drives the strip plate 6 to rotate through the mounting column 7, which can blow the foam in the digestion tank 1 onto the inner wall of the digestion tank 1 and break the foam, thereby eliminating the foam in the digestion tank 1 and improving the quality of the produced calcium hydroxide. At the same time, the electric cylinder 14 is started to drive the corresponding connecting block 13 to move in the mounting groove 12, which can also drive the mounting frame 11 to move, and drive the dispersing mechanism to move, thereby suppressing the foam in the digestion tank 1.
