Description

Technical Field

[0001] This utility model belongs to the field of zinc oxide alkaline washing technology, and in particular relates to a mixing reaction device for zinc oxide alkaline washing. Background Technology

[0002] Alkaline washing of zinc oxide refers to the process of cleaning zinc oxide with an alkaline solution. Its main purpose is to remove impurities from the surface of zinc oxide and improve its purity. Alkaline washing of zinc oxide is generally carried out in a mixing reaction device. Sodium hydroxide, zinc oxide and water are introduced into the mixing reaction device in a certain ratio, and the stirring component is driven to stir and mix the sodium hydroxide, zinc oxide and water to achieve alkaline washing of zinc oxide.

[0003] A search revealed a solid-liquid mixing reaction device disclosed in patent document CN212819873U, but it still has the following shortcomings in practical use:

[0004] 1. The solid-liquid mixing reaction device disclosed in the patent document with patent publication number CN212819873U has an inlet at the top of the cylinder and a rotating motor installed at the top of the cylinder. The rotating shaft connected to the output end of the rotating motor is rotatably connected to the top of the cylinder. There are stirring blades connected to the side wall of the rotating shaft. The material is introduced into the inside of the cylinder through the inlet. When the motor is powered on, the stirring blades rotate and stir the material inside the cylinder, so that the material is mixed and reacted. However, different types of materials are all introduced into the inside of the cylinder in a concentrated manner, which will cause material accumulation, which is not conducive to the full contact and reaction of different types of materials, and reduces the efficiency of the mixing reaction of materials.

[0005] 2. The solid-liquid mixing reaction device disclosed in the patent document with patent publication number CN212819873U has a discharge pipe connected to the lower edge of the outer wall of the cylinder. A flow limiting valve is installed on the discharge pipe, and a receiving part is set below the discharge pipe. When the flow limiting valve is opened, the solid material and water inside the cylinder enter the interior of the receiving part through the discharge pipe at the same time. However, it is inconvenient to discharge the water and solid material separately, which increases the workload of material filtration in the later stage.

[0006] To address these issues, we provide a mixing reaction apparatus for zinc oxide alkaline washing. Utility Model Content

[0007] The purpose of this utility model is to provide a mixing reaction device for zinc oxide alkaline washing. By setting up a feeding component, it is beneficial to fully mix and react zinc oxide and sodium hydroxide, thereby accelerating the alkaline washing efficiency of zinc oxide. Furthermore, by setting up a discharge component, water and solid materials are discharged separately, reducing the workload of subsequent filtration. This solves the technical problem mentioned in the background art of the solid-liquid mixing reaction device disclosed in the patent document with patent publication number CN212819873U.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0015] The present invention is further configured such that an installation box is mounted on the upper surface of the bucket lid, the main gear and the driven gear are both disposed inside the installation box, and the upper surface of the installation box is covered with an installation lid.

[0018] 1. This utility model, by setting up a feeding assembly, when the motor is powered on, the stirring shaft rotates, the stirring rod moves with the stirring shaft, and the disc rotates, so that the zinc oxide and sodium hydroxide inside the material cylinder are dispersed and evenly enter the interior of the reaction tank.

The rotating stirring shaft 204 and the stirring rod 204a stir and mix the materials entering the reaction tank 1. The zinc oxide and sodium hydroxide react to produce water and sodium zincate.

[0040] Example 3

[0041] Please see Figure 1 , Figure 5 and Figure 6 Based on specific embodiments one and two, a discharge assembly 3 is provided.

When the filter screen 302a is at its lowest point, it blocks the discharge of solid materials inside the reaction tank 1, and water is discharged through the filter screen 302a. When the filter screen 302a is at its highest point, the solid materials inside the reaction tank 1 are discharged through the discharge pipe 301, which facilitates the separate discharge of water and solid materials inside the reaction tank 1 and reduces the amount of subsequent filtration work.

[0042] Specifically, the discharge pipe 301 is connected and fixed to the lower edge of the outer wall of the reaction tank 1. The upper surface of the discharge pipe 301 has a through-connected mounting frame 302. Inside the mounting frame 302, there is a filter screen 302a.

[0043] Furthermore, the two ear blocks 302b are symmetrically arranged, and the two guide rods 303 are symmetrically arranged;

[0044] The operation process of this embodiment is as follows: When it is necessary to discharge the water inside the reaction tank 1, open the valve on the discharge pipe 301, and the water inside the reaction tank 1 enters the discharge pipe 301 and is discharged. The filter screen 302a traps the solid material inside the reaction tank 1. When it is necessary to discharge the solid material inside the reaction tank 1, pull the handle upward, the return spring 303a contracts, the lug 302b moves upward, the mounting frame 302 moves upward, and the filter screen 302a moves upward, releasing the filter screen 302a from blocking the solid material inside the reaction tank 1. The solid material inside the reaction tank 1 enters the discharge pipe 301 and is discharged. When the handle is released, the contracted return spring 303a gradually returns to its original position and extends, the mounting frame 302 moves downward, and the filter screen 302a moves downward to the lowest point position.
