[0031] The bottom of the cylinder 5 is divided into multiple liquid receiving areas by a partition. Each liquid receiving area is provided with a discharge port assembly 9 at the bottom, and a splash guard 10 is provided above the discharge port assembly 9.

[0032] The outer side of the cylinder 5 is provided with an annular electric heating tile 14, and the side of the cylinder 5 is provided with multiple feed port components 6, which are used to distribute molten material to each discharge port in proportion.

[0033] Cylinder 5 and top assembly: The top of cylinder 5 is equipped with an adjustment mechanism 1 and a distribution indicator assembly 2. The adjustment mechanism 1 is a manual and automatic adjustment mechanism, which is linked with the distribution indicator assembly 2. It can realize remote control of material distribution, and at the same time, it is convenient for operators to observe the position of the distribution cylinder from the outside and make precise adjustments.

[0034] The regulating mechanism 1 is connected to the internal distribution cylinder 15 via a rotating shaft 19. A graphite packing sealing assembly 3 and a nitrogen sealing assembly 4 are provided between the rotating shaft 19 and the top of the cylinder 5. The graphite packing assembly 3 achieves a seal at the rotating shaft, and the nitrogen sealing assembly 4 forms a nitrogen isolation chamber, effectively blocking corrosive gases such as alkaline vapors and preventing them from solidifying and jamming the regulating mechanism, while also preventing outside air from entering and corroding the equipment.

[0035] Distribution cylinder 15 assembly: The bottom of the distribution cylinder 15 is equipped with an anti-scouring plate 12 and a drain port 11. The anti-scouring plate 12 can prevent the feed from scouring the bottom of the cylinder and protect the distribution cylinder; the drain port 11 can discharge the molten material in the cylinder at any time to prevent it from solidifying in the tank and ensure that the molten material in the cylinder can be completely discharged when the device is stopped.

[0036] The outlet of the distribution cylinder 15 is equipped with a two-stage distribution component 16, which includes a primary distribution channel and a secondary distribution channel. The cross-sectional area of ​​the primary distribution channel is larger than that of the secondary distribution channel. Through the reasonable channel cross-sectional area design, the uniformity of the molten material distribution is achieved, making the material distribution more accurate.

[0037] The inside of the distribution cylinder 15 is equipped with a molten material temperature measuring instrument port 20, which is used to install temperature measuring instruments to monitor the temperature of the molten material in real time and provide data support for temperature control.

[0038] A maintenance short pipe 18 is provided at the rotating shaft 19 to facilitate the disassembly and maintenance of the distribution cylinder 15 and improve the maintainability of the equipment.

[0039] Bottom assembly of cylinder 5: The bottom of cylinder 5 is divided into multiple liquid receiving areas by a partition, and each liquid receiving area is equipped with a discharge port assembly 9 at its bottom. The discharge port assembly 9 adopts a punched forming structure, which can ensure the accuracy and quality of the discharge port.

[0040] A splash guard 10 is provided above the discharge port assembly 9 to prevent molten material from splashing into other discharge ports when it enters the anti-scouring box, thus ensuring the accuracy of the distribution.

[0041] A scouring box 13 is provided at the bottom of the liquid receiving area to prevent the discharge from the distribution cylinder from scouring and corroding the distributor body, thus extending the service life of the equipment.

[0042] Each discharge port assembly 9 is equipped with a steam purging assembly 7 at the top. When the device is stopped, the molten material can be completely purged and replaced by the steam purging assembly 7 to prevent the material from solidifying and clogging the pipe.

[0043] External components of cylinder 5: An annular electric heating tile 14 is provided on the outside of cylinder 5. The annular electric heating tile 14 is connected to a PID intelligent temperature control module with a temperature control accuracy of ±1℃. It can achieve uniform heating and stable temperature control of the molten material inside the cylinder and prevent the molten material from solidifying.

[0044] The cylinder 5 has multiple feed port components 6 on its side. The feed port components 6 are multi-inlet collaborative feeding structures that support dynamic adjustment of the distribution ratio of each discharge port. Molten material can be distributed to each discharge port in different proportions according to production needs, so as to achieve multi-directional adjustment.

[0045] Working Principle: In use, molten material enters through the multi-stage feed inlet assembly 6 and then into the distribution cylinder 15. The liquid level of the molten material gradually rises inside the distribution cylinder 15. When the liquid level is at the same height as the outlet, the molten material flows along the two-stage distribution assembly 16 into the anti-scouring box 13 in the receiving area. Because the outlet of the anti-scouring box has an embedded structure, the liquid inside the anti-scouring box 13 will slowly rise. When the liquid exceeds the height of the embedded tube, it enters the outlet assembly 9. By using the two-stage distribution assembly 16 with different distribution areas in each region, different proportions are distributed to each outlet. The distribution cylinder is equipped with a molten liquid temperature measuring instrument port 20 to monitor the temperature of the molten substance. A ring-shaped electric heating tile 14 is added around the cylinder body 5 to prevent the molten substance from solidifying in the receiving area. A nitrogen sealing assembly 4 is located at the top of the tank to protect the equipment from corrosion and prevent alkali vapor from condensing at the packing. A drain port 11 is installed at the bottom of the distribution cylinder to ensure that the molten substance inside the cylinder can be completely drained when the device is stopped. A splash guard 10 is installed between the distribution cylinder and the receiving area to prevent molten substance entering the anti-scouring box from splashing into other outlets. A steam purging assembly 7 is added to the top of each outlet assembly 9 to ensure that the molten substance can be completely purged and replaced when the device is stopped. The distribution cylinder 15 changes position as the automatic adjustment mechanism 1 rotates, achieving precise adjustment of the distribution angle. Manual operation can also be performed by referring to the distribution indicator panel 2.

[0046] Beneficial effects: The distributor base plate adopts an integral punching forming process and is fully circumferentially argon arc welded to the feed port assembly, which completely solves the bottom leakage problem;

[0047] An anti-erosion box 13 is installed at the bottom of the distributor to prevent the material discharged from the distribution cylinder 15 from eroding and corroding the distributor body, thus extending the service life of the equipment.

[0048] The top of the distributor is equipped with a manual / automatic adjustment mechanism 1 with a digital position display, which enables remote control of material distribution.

[0049] The top of the distributor is equipped with a nitrogen isolation chamber to effectively block alkaline vapors and prevent solidification from jamming the regulating mechanism 1;

[0050] The distribution cylinder 15 is equipped with a splash guard 10 to prevent alkali solution from splashing onto other discharge pipes;

[0051] The distributor cylinder 5 is equipped with an annular heating tile and a PID intelligent temperature control module with an accuracy of ±1℃, ensuring uniform heating and stable temperature.

[0052] The distributor adopts a two-stage distribution structure, which makes the material distribution more uniform and accurate;

[0053] Supports multiple inlet and outlet combinations, and allows for adjustment of material flow as needed;

[0054] The distribution cylinder 15 is equipped with a maintenance short pipe 18 to facilitate the disassembly and maintenance of the distribution cylinder 15.
