Description

Technical Field

[0001] This utility model relates to the field of washing device technology, and in particular to a high-efficiency water-saving device for washing heavy magnesium carbonate. Background Technology

[0002] Heavy magnesium carbonate, also known as hydrated basic magnesium carbonate, is a mixture of magnesium carbonate and magnesium hydroxide. Due to the high purity requirements of downstream applications, a deionized water washing process is required during production to ensure the purification effect. Generally, it needs to go through washing, filtration, secondary washing, and secondary filtration, and repeated washing to finally meet the cleaning requirements.

[0003] Therefore, in existing production equipment, materials are washed separately, that is, washed in two washing tanks in sequence. The solution passes through at least two washing tanks, which cannot achieve simultaneous washing and filtration. This wastes water and affects washing time, resulting in wastewater, time consumption and poor cleaning effect. Utility Model Content

[0020] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0021] This utility model provides a highly efficient water-saving device for washing heavy magnesium carbonate, such as... Figure 1As shown, tank 1 has a feed inlet 2 and a pure water inlet 3 at the top and a liquid outlet 4 at the bottom. Inside, an openable / closable filter screen 5 is located at the top, and a mounting plate 6 is located at the bottom. The mounting plate 6 has filter holes. The openable / closable filter screen 5 includes filter screen A and filter screen B, which can rotate relative to each other. Both filter screen A and filter screen B have several filter holes 5-1. When the filter holes 5-1 on the two filter screens are not connected, the filter screen is closed. When the filter holes 5-1 on the two filter screens are partially aligned, a first open state with smaller filter holes is formed, such as... Figure 2 As shown; when the filter holes 5-1 on the two filter screens are completely opposite to each other, a second open state with larger filter holes is formed, as shown. Figure 3 As shown.

[0022] The tank body 1 is also equipped with a pure water inlet II 7, a circulating liquid outlet 8, and a circulating liquid return outlet 9; such as Figure 1 As shown, the circulating return port 9 is located above the openable and closable filter screen 5, the pure water inlet II 7 and the circulating outlet 8 are both located between the openable and closable filter screen 5 and the mounting plate 6, and the circulating outlet 8 is located below the pure water inlet II 7.

[0023] A motor 10 is installed above the tank body 1. The motor 10 is connected to a stirring shaft 11. The stirring shaft 11 passes through the openable and closable filter screen and is fixed on the mounting plate 6. Multiple stirring rods 12 are installed on the stirring shaft 11 located below the filter screen.

[0024] This utility model provides a high-efficiency water-saving device for washing heavy magnesium carbonate. It is suitable for the washing process of heavy magnesium carbonate. The part above the openable and closable filter screen 5 in the tank 1 is the filter chamber, and the part between the openable and closable filter screen 5 and the mounting plate 6 is the washing chamber. The washing process is as follows:

[0025] Initial washing: With the filter screen closed, magnesium hydroxide and pure water are injected through feed inlet 2 and pure water inlet I3 respectively. Here, magnesium hydroxide and pure water mix to form a magnesium hydroxide aqueous solution slurry. The pure water washes away water-soluble impurity ions in the magnesium hydroxide to form waste liquid. The filter screen is opened to make it the first open state. The waste liquid reaches the washing chamber through the filter screen. The bottom valve is opened to discharge the waste liquid, completing the first filtration.

[0026] Before the first wash, the equipment is cleaned by injecting pure water into the washing device. Under the action of the stirring shaft 11 and the stirring rod 12, the residual impurities in the washing chamber are cleaned, and the wastewater generated during washing is discharged through the bottom waste liquid port.

[0027] Open the filter screen to enter the second state. The slurry, after preliminary filtration, enters the washing chamber. Pure water is injected through the pure water inlet II7 for the first wash. After the first wash, solid-liquid separation is achieved at the bottom. The wastewater is discharged after separation, and the material is reinjected with pure water to form a slurry. The slurry is then transported to the filtration device through a circulation device; the washing process is repeated.

[0028] Of course, in order to achieve the above process, one possible implementation is as follows: Figure 1 As shown, a water pump 13 is installed on the pipe between the circulating liquid outlet 8 and the circulating liquid return port 9; the tank 1 located below the mounting plate 6 is connected to the filtration pump, thereby facilitating the filtration of the liquid and improving the circulation rate.

[0029] The present invention provides a high-efficiency water-saving device for washing heavy magnesium carbonate. During washing, the device can control the stirring speed of the washing liquid through the motor 10, thereby improving the washing effect, reducing washing time and number of times, and making it easy to filter and wash with high output. During the washing process, the impurity removal efficiency is high, the water consumption is low, and no new harmful substances are introduced.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
