Description

Technical Field

[0001] The utility model relates to the technical field of adsorbent preparation, in particular to an impurity removal device used for preparing adsorbent by carbonizing industrial tea residues. Background Art

[0002] The carbonization of industrial tea residues to prepare adsorbents is a process involving multiple steps. First, as a porous material with a mesh structure, tea residues have a large surface area and adsorption capacity, making them a potential raw material for preparing adsorbents. Carbonization treatment is to partially decompose and transform the organic matter in the tea residues by controlling conditions such as temperature to form carbonized tea residues with a more stable structure and higher adsorption performance. During the carbonization process, the physical and chemical properties of the tea residues will change, such as a decrease in thermal weight loss and an increase in surface pores. These changes help to improve the adsorption capacity of carbonized tea residues for pollutants. By controlling carbonization conditions such as temperature, time, and atmosphere, the structure and properties of carbonized tea residues can be optimized to meet the needs of different adsorption applications. The carbonized tea residues can be used as an adsorbent to remove harmful substances in wastewater, such as heavy metal ions, organic pollutants, etc. Studies have shown that carbonized tea residues have high adsorption efficiency and selectivity for certain pollutants. In addition, tea residue biochar also has environmental and economic benefits. It can achieve "waste treatment with waste" and reduce the cost of adsorbent preparation. During the preparation process, the problem of impurity removal also needs to be considered. The existing impurity removal device for preparing adsorbents by carbonizing industrial tea residues can basically meet daily use needs, but there are still some shortcomings that need to be improved.

[0003] When using a filter cartridge to filter tea residues, the tea residues will be retained on the filter cartridge during the filtration process. If there are too many tea residues during the filtration process or they are not cleaned in time, the filter cartridge may be clogged. The clogging will not only affect the filtration effect, but also reduce the service life of the filter cartridge. For this reason, we propose an impurity removal device for preparing adsorbents by carbonizing industrial tea residues to solve the above problems. Utility Model Content

[0025] By arranging a rotatable cover plate 14 at the bottom of the second discharge port 5, the restoring force of the rotating rod 13 drives the torsion spring 12 to rotate in the fixed seat 11, and then the torsion spring 12 drives the cover plate 14 to cover the bottom of the second discharge port 5, so as to prevent mosquitoes from entering the second discharge port 5 and polluting the screening machine 1 when the screening machine 1 is restricted.

[0026] In other embodiments, the outer wall of the threaded block 10 is provided with five groups of cylinders, and the five groups of cylinders are arranged on the outer wall of the threaded block 10 at equal intervals;

[0027] This design makes it easier for workers to operate the thread block 10 so that the thread block 10 rotates along the thread on the slide rod 6, preventing the thread block 10 from being too tightly screwed with the thread on the slide rod 6, which would make it difficult or laborious for workers to operate the thread block 10.

[0028] In other embodiments, the surface of the rubber block 7 facing the filter cartridge 3 is set to be an arc with the same arc as the outer wall of the filter cartridge 3, and the rubber block 7 is made of rubber material;

[0036] The utility model provides an impurity removal device for preparing adsorbent by carbonizing industrial tea residues. The specific working principle is as follows:

[0037] When in use, first pull the threaded block 10 in the direction away from the screening machine 1, so that the threaded block 10 drives the slide bar 6 to slide in the screening machine 1, and the rubber block 7 squeezes the spring 8 toward the inner wall of the screening machine 1, and then rotate the threaded block 10 to make the threaded block 10 rotate on the slide bar 6. When it is necessary to clean the blockage on the filter cartridge 3, by loosening the slide bar 6, the restoring force of the spring 8 is used to push the rubber block 7 to reset and slide in the screening machine 1, and the rubber block 7 hits the filter cartridge 3, so that the blockage on the filter cartridge 3 falls off the filter cartridge 3, and then loosen the torsion spring 12, and use the restoring force of the rotating rod 13 to drive the torsion spring 12 to rotate, and the cover plate 14 is driven by the torsion spring 12 to fit with the bottom of the second discharge port 5, thereby achieving the purpose of protecting the bottom of the second discharge port 5.
