Description

Technical Field

[0001] The utility model relates to the technical field of landfill leachate treatment, and more specifically, to a concentrated liquid softening pretreatment device. Background Art

[0002] Landfill leachate is wastewater that seeps out of the garbage during its stacking and landfilling process due to fermentation, rainwater erosion, and infiltration into surface and groundwater. Its sources primarily include water contained in the garbage itself, water generated by biochemical reactions in the garbage, reverse osmosis from underground groundwater, and atmospheric precipitation. Concentrate is produced during the leachate treatment process using membrane treatment processes (such as nanofiltration and reverse osmosis). These membrane treatment processes can remove most pollutants from the leachate, but they also concentrate some difficult-to-degrade organic matter, inorganic salts, and heavy metals in the remaining liquid, forming a concentrate.

[0003] The traditional concentrated liquid softening pretreatment device has the following shortcomings: When the traditional concentrated liquid softening pretreatment device softens the concentrated liquid, chemical agents (such as quicklime, sodium hydroxide, sodium carbonate, etc.) are usually added to react with the calcium and magnesium ions in the concentrated liquid to generate precipitates or easily removable substances. However, during the addition process, the chemical agents will first react with the concentrated liquid above, resulting in the concentrated liquid at the bottom unable to fully react, affecting subsequent processing and use. Therefore, it needs to be improved. Utility Model Content

[0025] First, the concentrated liquid is discharged into the interior of the cylinder 1, and then the chemical agent is added into the cylinder 1 from the feed port 22, and then the cylinder 4 is started, so that the cylinder 4 drives the telescopic rod 5 to move upward, and the telescopic rod 5 drives the connecting shaft 6 to move upward, so that the connecting shaft 6 drives the long rod 8 to move upward, and the long rod 8 drives the circular plate 14 to move upward inside the long cylinder 13, so that the long cylinder 13 contacts the cylindrical block 11, thereby driving the arc plate 15 to move inside the arc groove 16, driving the circular plate 14 to rotate, and the circular plate 14 drives the stirring rod 18 to rotate, so that the stirring rod 18 rotates and moves upward, thereby improving the stirring efficiency inside the cylinder 1.

[0026] By starting the cylinder 4, the long rod 8 drives the circular plate 14 to move upward inside the long cylinder 13, thereby driving the arc plate 15 to move inside the arc groove 16, so that the stirring rod 18 rotates and moves upward, thereby improving the stirring efficiency in the cylinder 1. Compared with the traditional concentrated liquid softening pretreatment device, this concentrated liquid softening pretreatment device stirs the cylinder 1 by rotating and moving the stirring rod 18 up and down inside the cylinder 1, thereby improving the reaction efficiency.

[0027] Among them, a feed port 22 is provided on the surface of the top cover 19, a short shaft 20 is fixedly installed above the top cover 19, a long plate 21 is movably connected to the outer side of the short shaft 20, a rectangular groove 23 is provided inside the long plate 21, a rectangular plate 24 is movably installed inside the rectangular groove 23, an arc block 25 extending to the inside of the feed port 22 is fixedly installed below the rectangular plate 24, a handle 26 extending to the top of the long plate 21 is fixedly installed above the rectangular plate 24, and transverse grooves 27 are provided on both sides of the handle 26, and a return spring 28 is elastically installed between the inner side of the rectangular groove 23 and the upper side of the rectangular plate 24.

Release the handle 26, and the return spring 28 releases its elastic potential energy to push the rectangular plate 24 back to its original position.

[0042] The working principle and use process of this utility model:

[0043] First, the concentrated liquid is discharged into the interior of the cylinder 1, and then the chemical agent is added into the cylinder 1 from the feed port 22, and then the cylinder 4 is started, so that the cylinder 4 drives the telescopic rod 5 to move upward, and the telescopic rod 5 drives the connecting shaft 6 to move upward, so that the connecting shaft 6 drives the long rod 8 to move upward, and the long rod 8 drives the circular plate 14 to move upward inside the long cylinder 13, so that the long cylinder 13 contacts the cylindrical block 11, thereby driving the arc plate 15 to move inside the arc groove 16, driving the circular plate 14 to rotate, and the circular plate 14 drives the stirring rod 18 to rotate, so that the stirring rod 18 rotates and moves upward, thereby improving the stirring efficiency inside the cylinder 1.

[0044] When the feed port 22 needs to be opened, one only needs to press the transverse groove 27 with one hand, and then pull the handle 26 upward to make the rectangular plate 24 move upward inside the rectangular groove 23, thereby making the arc block 25 disengage from the inside of the feed port 22, and then move the long plate 21 to make the arc block 25 disengage from the top of the feed port 22, thereby exposing the feed port 22, making it easier to add chemicals into the cylinder 1. After adding, the arc spring 31 and the return spring 28 release their elastic potential energy to drive the arc block 25 back to its original position.
