Currently, alkali solution is typically prepared in a preparation tank, which comprises a tank body with a feed port and a liquid inlet at the top, a stirring mechanism within the tank, and a drain pipe at the bottom. During use, solid alkali in the form of blocks or flakes is added directly into the tank through the feed port, while the solution required for preparing the alkali solution is added to the tank through the liquid inlet.

[0035] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of this application.

[0036] like Figures 1-6 As shown:

[0037] An alkali solution preparation device provided in one embodiment of the present application includes a tank body 1, which is composed of a feed section 11, a crushing section 12, and a stirring section 13. The feed section 11 is located at the upper end of the crushing section 12, and the stirring section 13 is located at the lower end of the crushing section 12. The tank body 1 is connected to a liquid inlet pipe 14 and a liquid discharge pipe 15 with a valve. Specifically, the liquid inlet pipe 14 is connected to the top of the stirring section 13, and the liquid discharge pipe 15 is connected to the lower end of the stirring section 13. A crushing mechanism 2 is provided within the crushing section 12 of the tank body 1 for crushing flakes or lumps of solid alkali.

[0038] The feed section 11 of the tank body 1 is connected to a feeding structure 4 for adding solid alkali. Specifically, the feeding structure 4 includes a hopper 41, a hollow structure with one end open. A feed port 42 is defined at the top of the hopper 41, and a sealing cap 43 is installed at the feed port 42. The bottom of the hopper 41 is tilted to facilitate the flow of material into the tank body 1. A connection port 16 is defined at the side of the feed section 11 of the tank body 1. The side opening of the hopper 41 is sealed and fixedly connected to the connection port 16, ensuring communication between the hopper 41 and the tank body 1.

[0039] A stirring structure 5 is provided inside the stirring portion 13 of the tank body 1 and is located below the crushing mechanism 2 .

[0040] In this embodiment, a support frame 17 is fixed to the bottom of the tank body 1 for supporting the tank body 1 .

[0041] During use, the sealing cover 43 is opened, and solid alkali in the form of flakes or blocks is added into the hopper 41. The solid alkali in the form of flakes or blocks slides into the feeding part 11 of the tank body 1 according to its own gravity, and falls to the position of the crushing mechanism 2. At the same time, the crushing mechanism 2 is started. The crushing mechanism 2 crushes the solid alkali in the form of flakes or blocks, and breaks the solid alkali in the form of flakes or blocks into small particles. While crushing the solid alkali, the solution is injected into the stirring part 13, and the stirring structure 5 is started. After the solid alkali broken into small particles falls into the stirring part 13, the small particles of solid alkali are dissolved in the solution to form alkali solution under the stirring of the stirring structure 5, thereby completing the preparation of the alkali solution.

[0042] The alkali solution preparation device provided in this embodiment is provided with a crushing mechanism 2 for crushing flaky or lumpy solid alkali through the upper part of the tank body 1, and a feeding structure 4 for adding solid alkali is connected to the tank body 1, and the feeding structure 4 is located above the crushing mechanism 2. The interior of the tank body 1 is provided with a stirring structure 5 located below the crushing mechanism 2, so that when preparing the alkali solution, the flaky or lumpy solid alkali can be added to the tank body 1 and the flaky or lumpy solid alkali can be crushed into small particles. Under the action of the stirring structure 5, the small particles of solid alkali can be quickly dissolved in the solution relative to the flaky or lumpy solid alkali, thereby shortening the preparation time of the alkali solution and improving the preparation efficiency of the alkali solution.

[0043] In some embodiments of the present application, the crushing mechanism 2 includes a screen 21 having a conical ring structure, with the small diameter end of the screen 21 located above the large diameter end of the screen 21. A conical annular gap 22 is formed between the outer wall of the screen 21 and the inner wall of the tank body 1, and the annular gap 22 gradually decreases from top to bottom.

[0044] Specifically, the crushing part 12 of the tank body 1 is a conical structure, the small diameter end of the crushing part 12 of the tank body 1 is located above its large diameter end, and a conical annular gap 22 is formed between the inner wall of the crushing part 12 and the outer wall of the screen 21.

[0045] A dynamic crushing tooth structure 23 is fixed on the outer wall of the screen 21. The screen 21 is connected to a driving mechanism 24 that can drive it to rotate.

[0046] Furthermore, the size of the lower end of the annular gap 22 is equal to the mesh diameter of the screen 21, thereby improving the uniformity of the crushing of the solid alkali.

[0047] During use, the driving mechanism 24 is started, and the driving mechanism 24 drives the screen 21 to rotate, and the screen 21 drives the dynamic crushing tooth structure 23 to rotate with it. After the flake or block solid alkali enters the tank body 1, it falls into the annular gap 22. After the flake or block solid alkali enters the annular gap 22, the rotating dynamic crushing tooth structure 23 continuously impacts and crushes the flake or block solid alkali, breaking the flake or block solid alkali into small particles. The solid alkali that meets the particle size falls from the lower end of the screen 21 and the annular gap 22 into the stirring part 13, thereby completing the crushing of the flake or block solid alkali.

[0048] In this embodiment, a conical ring structure screen 21 is provided with a small diameter end located above its large diameter end, a dynamic crushing tooth structure 23 is provided on the screen 21, and an annular gap 22 of a conical structure is formed between the screen 21 and the inner wall of the tank body 1. When crushing, the solid alkali crushed into small particles can evenly enter the stirring part 13, that is, can evenly fall into the solution, thereby further shortening the stirring time of the stirring structure 5 while ensuring sufficient mixing.

[0049] In some embodiments of the present application, the dynamic crushing tooth structure 23 is composed of a plurality of crushing tooth groups 231 distributed up and down, and the crushing tooth group 231 includes a plurality of mounting plates 232 distributed in a ring shape, and a plurality of dynamic convex teeth 233 are fixed on the mounting plates 232, and the mounting plates 232 are fixed on the outer wall of the screen 21.

[0050] During use, after the screen 21 rotates, it drives the movable protruding teeth 233 at different positions to rotate synchronously. After the movable protruding teeth 233 rotate, the movable protruding teeth 233 hit the flake or block solid alkali at different positions to perform crushing work.

[0051] In order to improve the crushing effect, in some embodiments of the present application, the upper and lower adjacent mounting plates 232 are arranged in a staggered manner.

[0052] In some embodiments of the present application, a fixed crushing tooth structure 3 is provided inside the annular gap 22 , and the fixed crushing tooth structure 3 is fixedly connected to the inner wall of the tank body 1 .

[0053] In this embodiment, by setting a fixed crushing tooth structure 3, the movable convex tooth 233 continuously hits the flaky or blocky solid alkali, and the flaky or blocky solid alkali can hit the fixed crushing tooth structure 3, thereby increasing the number of times the flaky or blocky solid alkali is hit, and the flaky or blocky solid alkali can be quickly crushed.

[0054] In some embodiments of the present application, the fixed crushing tooth structure 3 includes a mounting ring 31, which is a conical structure. The mounting ring 31 is sleeved on the outside of the screen 21 and contacts and is fixedly connected to the inner wall of the tank body 1. A plurality of evenly distributed fixed convex teeth 32 are fixed on the inner wall of the mounting ring 31.

[0055] During use, after the movable convex teeth 233 continuously hit the flake-shaped or block-shaped solid alkali, the flake-shaped or block-shaped solid alkali will hit the fixed convex teeth 32, and the fixed convex teeth 32 can smash the flake-shaped or block-shaped solid alkali, so that under the synchronous action of the fixed convex teeth 32 and the movable convex teeth 233, the flake-shaped or block-shaped solid alkali can be quickly broken.

[0056] In some embodiments of the present application, the drive mechanism 24 includes a vertically distributed rotating shaft 241 that passes through the screen 21 and is fixedly connected to the screen 21. Specifically, the rotating shaft 241 is fixedly connected to the small diameter end of the screen 21, and a plurality of equally spaced reinforcing rods 6 are fixed between the rotating shaft 241 and the large diameter end of the screen 21 to improve the stability of the screen 21 when rotating with the rotating shaft 241.

[0057] The upper end of the rotating shaft 241 extends out of the upper end of the tank body 1 and is fixed with a motor 242 . The rotating shaft 241 is rotatably connected to the upper end of the tank body 1 , and the motor 242 is fixed above the tank body 1 through a bracket 243 .

[0058] The lower end of the rotating shaft 241 is fixedly connected to the stirring structure 5 .

[0059] During use, after the motor 242 is started, it rotates to drive the screen 21 to rotate and can also drive the stirring structure 5 to rotate.

[0060] In some embodiments of the present application, the stirring structure 5 includes a stirring shaft 51, which is fixedly connected to the rotating shaft 241. A plurality of stirring blades distributed up and down are installed on the stirring shaft 51, and the stirring rotating shaft 241 drives the stirring blades to rotate to perform stirring work.
