[0002] The production process of ternary precursors requires solid-liquid separation treatment. Existing solid-liquid separation equipment for ternary precursor production generally includes filter presses and disc dryers.

[0003] The liquid material in the material is filtered out by a filter press, and then the material after the initial solid-liquid separation is dried by a disc dryer to further remove the liquid material in the material. The filter press and disc dryer used in the existing solid-liquid separation equipment for ternary precursor production are both existing traditional equipment.

[0028] Advantages of the present invention:

[0029] 1) The filter press strengthening mechanism of the present invention includes a plurality of annular electromagnets and a plurality of negative pressure pipes. The annular electromagnets are respectively sleeved on the periphery of the corresponding material guide pipe and fixedly connected to the inner side of the corresponding filter cloth. The feed ends of the negative pressure pipes are respectively connected to the filter plates on the inner side of the filter cloth, and are used to evacuate the accommodating chamber on the filter plate. After the material enters between the filter cloths of two adjacent filter plates, as the feed pressure increases, the liquid material in the material gradually enters the accommodating chamber of the filter plate through the filter cloth. When the feed pressure reaches the set value, the annular electromagnet is energized, and the distance between the filter cloths of the two adjacent filter plates is reduced under the action of the adsorption force, so as to squeeze and filter out the liquid material in the filter cake; at the same time, the negative pressure extraction mechanism starts to extract negative pressure to accelerate the extraction and discharge of the liquid material in the filter cake. Thereby, while squeezing the filter cake, it can effectively form a negative pressure on the filter cake, and discharge the liquid material in the filter cake in two directions, thereby greatly improving the solid-liquid separation efficiency.

[0030] 2) The present invention also has a lower hopper fixedly installed on the lower side of the discharge end of the guide hopper. The top of the lower hopper is folded inward in an inverted L shape and is provided with a corresponding cover. The discharge end of the guide hopper extends through the cover. When the filter cake after filtration is discharged into the guide hopper, the material is initially crushed by collision. The crushed material enters the cover of the lower hopper through the guide hopper. As the sieve plate rotates, the crushing convex edge drives the material through the baffle plate. Under the cooperation of the crushing convex and the baffle plate, the material is sheared and crushed. The crushed material is evenly screened out through the sieve holes on the sieve plate, thereby effectively and directly crushing the filter cake and outputting it, so that the material after solid-liquid separation can directly enter the corresponding drying equipment for drying processing, so as to enhance the use function of the present invention.

[0031] 3) The annular electromagnets on the filter plates at the ends of the present invention are provided with corresponding plug-in shafts on the sides that are not connected to the filter cloth, and the plug-in shafts are respectively movably plugged into the filter plates at the ends; and the annular electromagnets on both sides of the filter plates at the middle that are not connected to the filter cloth are respectively fixed with guide sleeves and guide shafts that form a movable docking with each other. The load of the annular electromagnets is transferred to the filter plates, thereby preventing the filter cloth from being overloaded due to the setting of the annular electromagnets, and ensuring the practical effect of the present invention.

[0032] 4) The present invention not only improves the structure of the first scraper mechanism and the second scraper mechanism, but also adds a scraper driving mechanism, which includes a plurality of circles of magnet sheets fixedly connected to the upper sides of the first heating disk and the second heating disk in an annular array at intervals. When the first scraper and the second scraper rotate and pass the position of the magnet sheets, the first scraper and the second scraper are adsorbed, and the first limit spring and the second limit spring are compressed. When the compression force of the first limit spring and the second limit spring is greater than the adsorption force of the magnet sheets, the first scraper and the second scraper leave the position of the magnet sheets and swing under the elastic force of the first limit spring and the second limit spring, so as to break up the materials when scraping them, thereby effectively breaking up the materials simultaneously during the process of shoveling and pushing the materials, so as to improve the contact uniformity and contact rate between the materials and the heating disk, thereby effectively improving the drying effect of the materials.

[0054] A feed pipe 7 is fixedly mounted on the other end of the guide bracket 2, the feed end of the feed pipe 7 is pumped to an external material source, and the discharge end of the feed pipe 7 is connected to a guide pipe 402 of the filter plate 4 at the end, so as to pump the material into between the filter cloths 5 of two adjacent filter plates 4;

[0055] The filter press strengthening mechanism comprises a plurality of annular electromagnets 801 and a plurality of negative pressure pipes 802. The annular electromagnets 801 are respectively sleeved on the periphery of the corresponding material guide pipes 402 and fixedly connected to the inner side of the corresponding filter cloth 5. The feed ends of the negative pressure pipes 802 are respectively connected to the filter plates 4 on the inner side of the filter cloth 5, and are used to evacuate the accommodating chamber 401 on the filter plate 4. The plurality of negative pressure pipes 802 are connected in parallel to the corresponding negative pressure mechanism. When the material enters between the filter cloths 5 of two adjacent filter plates 4, the annular electromagnets 801 are energized, and the distance between the filter cloths 5 of the two adjacent filter plates 4 is reduced under the action of the adsorption force, so as to squeeze and filter out the liquid material in the filter cake. At the same time, the negative pressure mechanism starts to pump negative pressure to accelerate the extraction of the liquid material in the filter cake.

[0056] The feed end of the disc dryer is connected to the discharge end of the guide hopper 3 of the filter press through a corresponding material transmission mechanism 30, which is used to heat and dry the material after the filter press.

The feed ends of the negative pressure extraction pipes 802 are respectively connected to the filter plates 4 on the inner side of the filter cloths 5, and are used to vacuum the accommodating chambers 401 on the filter plates 4. After the material enters between the filter cloths 5 of two adjacent filter plates 4, as the feed pressure increases, the liquid material in the material gradually enters the accommodating chambers 401 of the filter plates 4 through the filter cloths 5. When the feed pressure reaches the set value, the annular electromagnets 801 are energized, and the spacing between the filter cloths 5 of the two adjacent filter plates 4 is reduced under the action of the adsorption force, so as to squeeze and filter out the liquid material in the filter cake; at the same time, the negative pressure extraction mechanism starts to extract the negative pressure to accelerate the extraction of the liquid material in the filter cake. In this way, the filter cake can be squeezed and negative pressure can be effectively formed on the filter cake, so that the liquid material in the filter cake can be discharged in two directions, thereby greatly improving the solid-liquid separation efficiency.
