Description

Technical Field

[0001] The utility model relates to the technical field of mixed salt crystallization filtration, in particular to a mixed salt crystallization filtration device. Background Art

[0002] A mixed salt crystallization and filtration device is a device used to process solutions containing multiple salt components, separating and filtering the salts through a crystallization process. A mixed salt crystallization and filtration device typically consists of a crystallizer, a heating system, a cooling system, and a filtration system. When using the mixed salt crystallization and filtration device, a solution containing multiple salt components is first added to the crystallizer, and its concentration and temperature are adjusted to an appropriate range. The heating system is then activated to heat the solution, causing the water in the solution to gradually evaporate. As the water evaporates, the solute concentration in the solution gradually increases, reaching a supersaturated state. In this supersaturated state, the solute begins to precipitate and form crystals.

[0003] For example, the Chinese patent "A Filtration Device for Crystallization and Evaporation of Salt-Producing Wastewater" with publication number CN208711174U includes a fixed frame, a walking wheel is provided at the bottom of the fixed frame, a ton bag for filtering water is provided in the middle of the fixed frame, at least three hanging ears are provided at the upper end of the fixed frame, the slings of the ton bag are hung on the hanging ears, a grating plate is provided at the bottom of the fixed frame, and the fixed frame specifically includes at least three columns, the lower ends of the at least three columns are fixedly connected by a hollow frame, and a grating plate connected to the hollow frame is provided inside the hollow frame.

[0004] Although the above-mentioned existing technology can achieve the filtration of salt crystals, in actual use, on the one hand, the particulate matter in the mixed salt solution is easy to cause the filter screen to be blocked when filtering, and the larger particle crystals in the mixed salt solution are easy to cause the mesh of the filter plate to be blocked when filtering the mixed salt solution, thereby affecting the filtration effect. On the other hand, it is difficult to perform subsequent operations on the crystallization of the mixed salt. After the mixed salt solution is crystallized, it is directly taken out of the filtration device, resulting in residual solution adhering to the surface of the crystal, thereby reducing the purity of the mixed salt crystals. Therefore, it does not meet the existing needs. In this regard, we propose a mixed salt crystallization filtration device. Utility Model Content

[0005] The purpose of the utility model is to provide a mixed salt crystallization filtration device to solve the problems raised in the above background technology that the particles in the mixed salt solution easily cause filter blockage during filtration and it is difficult to perform subsequent operations on the crystallization of the mixed salt.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model can heat the mixed salt solution by the heating wire and the rotating disk. When the mixed salt solution is heated, the rotating rod is rotated first, and the rotating disk is driven to rotate inside the rotating chamber by the rotation of the rotating rod. At this time, the second through hole on the rotating disk and the first through hole on the intercepting plate no longer coincide with each other. The heating wire is energized, and after the current flows through the heating wire with uniform resistance, the heating wire itself generates heat and transfers the generated heat to the wall of the heating tube. At this time, the mixed salt solution is poured into the filter tank through the liquid inlet pipe. Since the lower end of the heating tube is sealed by the intercepting plate and the rotating disk, the mixed salt solution is located in the heating tube. At the same time, the heat on the wall of the heating tube is transferred to the mixed salt solution, the temperature of the mixed salt solution increases and the crystals therein are dissolved. After a period of time, the intercepting plate is opened to allow the mixed salt solution to drip into the filter box, thereby preventing the large particles in the solution from crystallizing and causing clogging of the filter plate, thereby improving the filtering effect of the filter plate.

[0015] 2. The utility model can clean the mixed salt after crystallization through the spray pipe and the water inlet pipe. When the mixed salt crystals are filtered, pure water is poured into the water inlet pipe, and the pure water flows into different spray pipes through the liquid separation pipe. At this time, the pure water is sprayed out from the spray pipe, and the mixed salt crystals are sprayed and cleaned by the pure water to avoid the mixed salt solution residue adhering to the surface of the mixed salt crystals, thereby improving the purity of the mixed salt crystals.

[0016] 3. The utility model can make it easier to remove the mixed salt crystals through the spring and the filter plate. When the mixed salt crystals have finished filtering, open the tank cover and take out the heating tube from the filter tank. At this time, pull the filter box upward in the filter tank until the filter box is taken out of the filter tank. At this time, the mixed salt crystals are located on the filter plate inside the filter box. Then push the lower end of the filter plate to move the filter plate upward in the filter box. At the same time, the spring is in a stretched state until the filter plate is pushed out of the filter box. At this time, remove the mixed salt crystals, making it easier to remove the mixed salt crystals, thereby improving the efficiency of removing the mixed salt crystals.

Since the lower end of the heating tube 8 is sealed by the intercepting plate 10 and the rotating disk 11, the mixed salt solution is located in the heating tube 8. At the same time, the heat on the wall of the heating tube 8 is transferred to the mixed salt solution, the temperature of the mixed salt solution increases and the crystals therein are dissolved. After a period of time, the intercepting plate 10 is opened to allow the mixed salt solution to drip into the filter box 18.

The rotating rod 6 extends to the top of the tank cover 4 through the liquid inlet pipe 5. The diameter of the horizontal plate at the upper end of the rotating rod 6 is smaller than the opening diameter of the liquid inlet pipe 5, which makes it easy to drive the rotating disk 11 to rotate through the rotating rod 6.

Springs 19 are fixedly provided at the four corners of the lower end of the filter plate 20. The other end of the spring 19 is fixedly connected to the horizontal plate at the lower end of the filter box 18, so that the mixed salt crystals can be removed more conveniently through the filter plate 20.

A valve 21 is fixedly provided on the outside of the liquid outlet pipe 22, so as to facilitate adjusting the opening and closing of the liquid outlet pipe 22 through the valve 21.

[0031] Working principle: When the mixed salt crystals are filtered, pure water is poured into the water inlet pipe 7, and the pure water flows into different spray pipes 15 through the liquid separator 14. At this time, pure water is sprayed out from the spray pipe 15, and the mixed salt crystals are sprayed and cleaned by the pure water. When the mixed salt crystals are filtered, the tank cover 4 is opened and the heating tube 8 is taken out of the filter tank 3. At this time, the filter box 18 is pulled upward in the filter tank 3 until the filter box 18 is taken out of the filter tank 3. At this time, the mixed salt crystals are located on the filter plate 20 inside the filter box 18, and then the lower end of the filter plate 20 is pushed to move the filter plate 20 upward in the filter box 18. At the same time, the spring 19 is in a stretched state until the filter plate 20 is pushed out of the filter box 18. At this time, the mixed salt crystals are removed.
