Description

Technical Field

[0001] This utility model relates to the technical field of mixing devices for mixed solutions inside a reactor, and in particular to a special purifier for bottom blowing and stirring of a wet metallurgical reactor. Background Technology

[0002] Hydrometallurgy is a process in which water, mineral powder, and acid (alkali) are mixed together and chemically reacted to transfer the useful solid metals contained in the raw materials into the liquid phase, so as to separate and recover various useful metals. The working temperature of hydrometallurgy is room temperature or low temperature.

[0003] Currently, hydrometallurgical processes typically require reactors equipped with agitators to stir the hydrometallurgical mixture. Most existing reactors use permeable bricks at the bottom for aeration. These permeable bricks are mainly of two types: slit-type and diffused-type. Slit-type permeable bricks have a large air permeability, but they exhibit a phenomenon where airflow stops after a cross section, and the airflow is not dense enough, affecting the stirring force of the mixture and the stirring rhythm. Diffuse-type permeable bricks produce small, uniform gas bubbles, resulting in good purification, but their air permeability is smaller, also affecting the stirring force of the mixture. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a special purifier for bottom blowing and stirring of hydrometallurgical reactors.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a special purifier for bottom blowing and stirring of a hydrometallurgical reactor, including a purifier body, a cylindrical slit-type air-permeable core at the center of the purifier body, a spiral-shaped air-blowing slit inside the slit-type air-permeable core, a diffused air-permeable ring sleeved on the outside of the slit-type air-permeable core, the diffused air-permeable ring being frustoconical with its large end facing upward and its small end facing downward, an annular gap between the slit-type air-permeable core and the slit-type air-permeable core, and an air-blowing section communicating with the slit-type air-permeable core, the annular gap and the diffused air-permeable ring on the purifier body.

[0006] As a preferred embodiment, the air blowing section includes an air chamber located at the bottom of the purifier body and an air blowing pipe communicating with the air chamber. The air chamber is connected to an annular gap, a diffused air-permeable collar, and an air blowing slit.

[0007] As a preferred option, the diffused breathable collar has micropores inside, and the micropores inside the diffused breathable collar are interconnected.

[0008] As a preferred embodiment, there are multiple air-blowing slits, and the projections of the multiple air-blowing slits on the upper surface of the slit-type breathable core are arranged in a rotating radial pattern.

[0009] As a preferred option, the slit-type ventilated core is formed by casting, machine pressing, or isostatic pressing.

[0010] As a preferred option, the diffused ventilated collar is formed by casting, machine pressing, or isostatic pressing.

[0011] The beneficial effects of this application are as follows: 1. By setting a slit-type air-permeable core and a diffused air-permeable ring, this application forms a combination of slit-type and diffused air blowing, which ensures both the density of the airflow and the volume of air flow, and greatly improves the stirring force of the wet metallurgical mixed solution.

[0012] 2. This application sets up spiral-shaped air-blowing slits, and the projection of multiple air-blowing slits on the upper end surface of the slit-type air-permeable core is in a rotating radial pattern, so that the blown gas is a rotating airflow. The rotating airflow increases the reaction interface of the hydrometallurgical mixed solution, thereby making the stirring of the hydrometallurgical mixed solution more thorough, improving the stirring efficiency and stirring effect, so as to meet the requirements of smelting high-quality products, and at the same time shortening the smelting time.

[0017] Please see Figure 1-2This utility model provides a special purifier for bottom blowing and stirring of a hydrometallurgical reactor, including a purifier body 1. The purifier body 1 has a cylindrical slit-type air core 3 at its center. The slit-type air core 3 has a spiral-shaped blowing slit 31 inside. A diffused air-permeable ring 2 is sleeved on the outside of the slit-type air core 3. The diffused air-permeable ring 2 is frustoconical, with the large end of the diffused air-permeable ring 2 facing upward and the small end facing downward. There is an annular gap 4 between the slit-type air core 3 and the slit-type air core 3. The purifier body 1 is also provided with an air blowing section that communicates with the slit-type air core 3, the annular gap 4 and the diffused air-permeable ring 2.

[0018] Among them, combined Figure 1 As shown, the air blowing section includes an air chamber 11 disposed at the bottom of the purifier body 1 and an air blowing pipe 12 communicating with the air chamber 11. The air chamber 11 is connected to an annular gap 4, a diffusion-type breathable collar 2, and an air blowing slit 31. The annular gap 4 can serve as an annular slit of the purifier.

[0019] Specifically, there are multiple air-blowing slits 31, and the projections of these multiple air-blowing slits 31 onto the upper surface of the slit-type venting core 3 are arranged in a rotating radial pattern. This application, by setting spiral-shaped air-blowing slits 31, and ensuring that the projections of these multiple air-blowing slits 31 onto the upper surface of the slit-type venting core 3 are arranged in a rotating radial pattern, results in a rotating airflow. This rotating airflow increases the reaction interface in the hydrometallurgical mixture, thereby making the stirring of the hydrometallurgical mixture more thorough, improving stirring efficiency and effect, thus meeting the requirements for smelting high-quality products, and also shortening the smelting time.
