Description

Technical Field

[0001] This utility model belongs to the field of casting and metallurgical technology, specifically a slag separation device for cast iron smelting. Background Technology

[0002] In the cast iron smelting process, the uniform distribution of the furnace charge and heat conduction have a significant impact on smelting efficiency. Patent CN112880410B, entitled "A Charging Device for Cast Iron Parts Smelting," discloses a material oscillation mechanism that achieves uniform distribution of the furnace charge through a swaying box and sieve plate structure, significantly improving smelting efficiency. However, this device mainly addresses the issues of charge addition and distribution, and does not address the separation of molten slag from molten iron during the smelting process. In actual production, slag-molten iron mixing is common in the later stages of smelting, potentially leading to impurity residue and affecting the quality of the final product. Therefore, effectively separating molten slag from molten iron during the smelting process has become an urgent technical problem to be solved. Utility Model Content

[0033] Specifically, a guide plate 35 is also provided at the bottom of the filter cartridge 31 to direct the solution to the discharge assembly 34.

[0034] Specifically, the base 1, storage basin 21, filter cylinder 31, guide plate 35 and discharge assembly 34 are all made of high chromium nickel alloy steel, and the filter screen 33 is made of silicon carbide ceramic filter screen.

[0035] In this embodiment, the base 1, the slag skimming assembly 2, and the filter assembly 3 constitute a cast iron smelting slag liquid separation device according to this application.

[0036] Example 2:

[0037] Specifically, the scraping assembly 22 includes: an electric push rod 221, which is fixedly connected to the storage basin 21 by a mounting bracket and is surrounded by a housing with heat dissipation holes; a scraper 222, which is fixedly connected to the output end of the electric push rod 221 and is slidably disposed on the top surface of the storage basin 21; and an impurity collection box 223, which is fixedly connected to the side walls on both sides of the storage basin 21 and is used to collect the impurities scraped by the scraper 222.

[0038] The electric actuator 221 uses the JWB-1000-500, which has an aluminum alloy shell, built-in overload protection, and is suitable for high-temperature environments.

[0039] It should also be understood that the electric actuator 221 is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0040] In this embodiment, the electric push rod 221 drives the scraper 222 to slide on the surface of the storage basin 21, scraping impurities into the impurity collection box 223 to remove floating impurities from the surface of the sludge liquid.

[0041] Example 3:

[0042] Specifically, the valve assembly 23 includes: a cylinder 231, which is fixedly connected to the side wall of the storage basin 21 via a mounting bracket and a housing, the housing being provided with heat dissipation holes; a support member 232, which is fixedly connected to the bottom of the storage basin 21; and a baffle 233, which is slidably connected to the bottom surface of the storage basin 21, one end of which is fixedly connected to the output end of the cylinder 231 via a connecting rod, and the other end is slidably connected to the support member 232.

[0043] Cylinder 231 is a piston-type cylinder made of heat-resistant sealing material, which is suitable for the temperature of cast iron smelting environment.

[0044] It should also be understood that cylinder 231 is common knowledge in the field, and it is only used without modification, so the control method and circuit connection will not be described in detail.

[0045] In this embodiment, cylinder 231 drives baffle 233 to slide, controlling the opening and closing of the drain port at the bottom of storage basin 21, thereby realizing the on / off control of sludge discharge.

[0048] With this configuration, protrusion 1 (323) slides in the mounting groove (322), and adjusting screw (321) is used to fix protrusion 1 (323), so as to realize the installation and removal of filter screen (33) and facilitate the replacement and maintenance of filter screen (33).

[0049] Example 5:

[0050] Specifically, the discharge assembly 34 includes: a discharge port 341, which is located at the bottom of the filter cylinder 31; a baffle 342, which is located in the groove of the filter cylinder 31, and a protrusion 2 is fixedly connected above it to block the discharge port 341; and a fixing block 343, which is welded to the side wall of the filter cylinder 31, located above the groove of the filter cylinder 31, and connected to the protrusion 2 of the baffle 342 through a connecting sleeve.

[0051] In this process, by connecting and disconnecting the connecting sleeve of the fixed block (343) and the second protrusion, the second baffle (342) is controlled to slide in the chute, blocking or opening the discharge port (341) and controlling the discharge of the filtered liquid.

[0052] In actual use, the operator first installs the filter screen 33. First, the protrusion 323 is welded to the side wall of the filter screen 33. Then, the filter screen 33 is placed into the filter cylinder 31, and the protrusion 323 slides along the mounting groove 322 to the bottom of the groove. Next, the filter screen 33 is rotated so that the threaded hole on the protrusion 323 aligns with the adjusting screw 321. Then, the adjusting screw 321 is rotated to lock the position of the filter screen 33. The solution to be separated is then poured into the storage basin 21 and allowed to stand. After the scum floats to the surface of the solution, the electric push rod 221 is activated, causing the scraper 222 to slide back and forth on the top of the storage basin 21 to scrape away impurities from the solution surface. After cleaning, the electric push rod is turned off. Push rod 221 activates cylinder 231, which moves baffle 233, causing the solution to flow out of the outlet of storage basin 21. The solution passes through filter screen 33, leaving the remaining impurities on the filter screen 33. Under the guidance of guide plate 35 at the bottom of filter cylinder 31, the solution flows to outlet 341. At this time, outlet 341 is located at the bottom of the slide groove of filter cylinder 31, blocking outlet 341. When solution needs to flow out, protrusion 2 on baffle 342 can be moved to move outlet 341 to the top of slide groove of filter cylinder 31. Then, protrusion 2 on baffle 342 is connected to the connecting sleeve on fixing block 343 to fix baffle 342 and allow solution to flow out.
