[0010] Preferably, the outer side of the insert block is designed to be conical, and the insert block fits in the interior of the slot.

[0011] Preferably, the outer side of the limiting ring slides with the outer side of the insert block, the limiting ring fits with the inner side of the limiting groove, and the protrusion fits with the inner side of the groove at the corresponding position.

[0012] Preferably, the push block is slidably connected to the inside of the installation slot, and the push rod is slidably connected to the inside of the installation slot.

[0013] Compared with the prior art, the beneficial effect of the high-efficiency smelting device for ductile iron castings proposed by the utility model is that by inserting the filter screen on the lower side of the impurity removal block and limiting it with a limit ring, there is no need to use bolts to replace the filter screen, which makes the operation of the workers more convenient.

[0024] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figures 1-8 When the sieve 5 is in the air, it is rotated to move the sieve 5. When the sieve 5 is in the air, it is rotated to move the sieve 5. When the sieve 5 is in the air, it is rotated to move the sieve 5. When the sieve 5 is in the air, it is rotated to move the sieve 5. When the sieve 5 is in the air, it is rotated to move the sieve 5. When the sieve 5 is in the air, it is rotated to move the sieve 5. When the sieve 5 is in the air, it is rotated to move the sieve 5.

[0026] When the filter screen 5 needs to be replaced, the mounting ring 4 is pulled downward so that the mounting ring 4 can drive the filter screen 5 to move downward through the connecting block 6, thereby making it easy to remove the filter screen 5. Conversely, the filter screen 5 is slid into the interior of the impurity removal block 3, and the connecting block 6 is slid into the interior of the impurity removal block 3, so that the mounting ring 4 is connected to the impurity removal block 3, thereby making it easy to install the filter screen 5, and there is no need to use bolts to replace the filter screen 5, making it more convenient for workers to operate, and thus will not affect the efficiency of the next smelting of raw materials.

[0027] Example 2: On the basis of Example 1, in order to achieve more stable installation of the filter 5, multiple slots 7 are opened inside the top of the mounting ring 4, and multiple connecting rods 17 are fixedly connected to the outside of the bottom end of the debris removal block 3. The outside of the connecting rod 17 is fixedly connected to the plug-in block 8. The outer side of the plug-in block 8 is designed with a conical surface, and the plug-in block 8 fits in the inside of the slot 7, so that the plug-in block 8 can be easily slid into the inside of the slot 7.

[0028] When the mounting ring 4 slides into the outside of the debris removal block 3, the insert block 8 is able to slide into the inside of the slot 7 and is squeezed and deformed by the slot 7. When the mounting ring 4 is fitted with the debris removal block 3, the insert block 8 is able to perform a reset movement, thereby allowing the insert block 8 to be filled into the inside of the slot 7, making the connection between the mounting ring 4 and the debris removal block 3 more stable. Conversely, when the debris removal block 3 is separated from the mounting ring 4, the conical surface on the upper side of the insert block 8 is able to fit into the inside of the slot 7 and slide, thereby allowing the insert block 8 to be easily detached from the inside of the slot 7.

[0029] Embodiment 3: On the basis of embodiment 2, in order to achieve more stable installation of the filter screen 5, a limiting groove 9 is provided on the outer periphery of the bottom end of the debris removal block 3, and a plurality of grooves 10 are provided inside the limiting groove 9. The inner side of the slot 7 is slidably connected with a plurality of limiting rings 11. The slot 7 limits the limiting ring 11, so that the limiting ring 11 will not deviate when sliding. The outer side of the limiting ring 11 slides with the outer side of the plug block 8, so that the plug block 8 can push the limiting ring 11 to move inward. The limiting ring 11 fits with the inner side of the limiting groove 9, thereby making the installation of the mounting ring 4 more stable. The inner side of the limiting ring 11 is fixedly connected with a plurality of protrusions 12, and the protrusions 12 fit with the inner side of the grooves 10 at the corresponding positions, thereby making the installation of the filter screen 5 more stable.

[0030] When the plug block 8 is inserted into the slot 7, the plug block 8 pushes the limiting ring 11 at the corresponding position to move inward, so that the limiting ring 11 can fit into the inside of the limiting groove 9, and the protrusion 12 can fit into the inside of the groove 10, so that the installation of the mounting ring 4 is more stable, and the installation of the filter screen 5 is more stable.

[0031] Example 4: On the basis of Example 3, in order to realize automatic resetting of the limiting ring 11, a plurality of mounting grooves 13 are opened inside the mounting ring 4, and a plurality of elastic members 14 are fixedly connected to the inner wall of the mounting groove 13, and a push block 15 is fixedly connected to the other end of the elastic member 14, and the push block 15 is slidably connected to the inside of the mounting groove 13. The mounting groove 13 limits the push block 15, so that the push block 15 will not deviate when sliding, and the end of the push block 15 away from the elastic member 14 is fixedly connected to a push rod 16, and the push rod 16 is slidably connected to the inside of the mounting groove 13. The mounting groove 13 limits the push rod 16, so that the push rod 16 can slide smoothly, and the end of the push rod 16 away from the push block 15 is fixedly connected to the limiting ring 11.

[0032] When the limit ring 11 moves inward, the limit ring 11 drives the push rod 16 to move inward, and then the push rod 16 pulls the push block 15 to move inward, so that the push block 15 pulls the elastic member 14 to deform. When the insert block 8 no longer squeezes the limit ring 11, the elastic member 14 is able to perform a reset movement, and then the elastic member 14 pulls the push block 15 to move outward, so that the limit ring 11 is able to detach from the inside of the limit groove 9 and enter the inside of the mounting ring 4.

[0033] In actual use, by pulling the mounting ring 4 downward, the mounting ring 4 can drive the filter screen 5 downward through the connecting block 6, and the conical surface of the upper side of the plug block 8 can slide inside the slot 7, thereby making the plug block 8 disengage from the slot 7, so that the plug block 8 no longer squeezes the limit ring 11. At this time, the elastic member 14 can perform a reset movement, thereby making the elastic member 14 pull the push block 15 to move outward, thereby making the limit ring 11 disengage from the inside of the limit groove 9 and enter the inside of the mounting ring 4, thereby making it convenient to disassemble the filter screen 5. Conversely, when the mounting ring 4 slides into the outside of the debris removal block 3, the plug block 8 can slide into the inside of the slot 7 and be squeezed by the slot 7 to produce a shape When the mounting ring 4 is fitted with the impurity removing block 3, the insert block 8 is able to perform a reset movement, thereby allowing the insert block 8 to be filled in the interior of the slot 7, making the connection between the mounting ring 4 and the impurity removing block 3 more stable, and allowing the insert block 8 to push the limiting ring 11 to move inward, and the limiting ring 11 is able to drive the push rod 16 to move inward, thereby allowing the push rod 16 to pull the push block 15 to move inward, allowing the push block 15 to pull the elastic member 14 to deform, and then there is no need to use bolts to replace the filter 5, making the worker's operation more convenient, and thus not only making the installation of the filter 5 more stable, but also allowing the filter 5 to be conveniently replaced, thereby not affecting the next smelting efficiency of the raw materials.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
