Description

Technical Field

[0001] The invention relates to the technical field of molding sand processing, in particular to a molding sand separator that realizes gapless operation. Background Art

[0002] Molding sand is generally made of raw sand for casting, molding sand binder and additives and other molding materials mixed in a certain proportion. Molding sand can be divided into clay sand, water glass sand, cement sand, resin sand, etc. according to the different binders used. Clay sand, water glass sand and resin sand are the most used. The role of molding sand in casting production is extremely important. The casting waste caused by poor quality of molding sand accounts for about 30% to 50% of the total casting waste. The molding sand separator is a device used to separate and screen impurities, old sand and effective sand in the molding sand. For example, in a foundry, the use of a molding sand separator can quickly process a large amount of used molding sand, screen out the reusable part, and put it back into production, thereby reducing production costs and improving the quality of castings.

[0018] S1: After the waste molding sand materials generated by the casting process are uniformly recycled, they are continuously transported by relevant transportation equipment and fed into the coarse material processing mechanism. They first fall along the feeding rack to the top of the limiting cone rod. Some waste molding sand with special shapes or waste molding sand with blocks larger than the gap between the limiting cone rods are intercepted and retained, and the small pieces of waste molding sand that are not intercepted fall to the top of the upper grinding rack;

[0019] S2: Adjacent crushing mechanisms approach each other along the limiting cone rod, and push and crush the larger waste sand. When the retaining block is driven by the tension rod to slide along the inner wall of the limiting cone rod, the side of the limiting cone rod is provided with a tooth groove, which meshes with the external gear, and the external gear meshes with the internal gear. The internal gear drives the rotating edge block to rotate through the inner shaft rod;

[0020] S3: The conical groove and the rotating cone surface are both provided with some irregular convex blocks. The medium-sized particles of waste molding sand entering the conical groove are driven by the rotating cone and roll along the inside of the conical groove. The inflated airbag drives the convex column to extend reciprocally into the conical groove, so that the medium-sized particles of waste molding sand are disturbed by the convex blocks and convex columns during rolling in the rotating cone and the conical groove, forming a multi-stage crushing process to form small and medium-sized particles of waste molding sand;

[0021] The sliding beam drives the movable cone plate to move up and down between the fixed cone plates, causing the small and medium-sized particles of waste sand entering between the two to be crushed by friction;

[0022] S4: Small and medium-sized particles of waste molding sand continuously fall on the conveying frame, which transports them to the drop port. The adjusting shaft rod is connected and adjusted through an external tool, driving the arc plate to rotate along the bottom of the material leveling cover, so that the distance between the bottom of the arc plate and one end of the conveying frame can be adjusted, so that the small and medium-sized particles of waste molding sand unevenly accumulated on the conveying frame are scraped off by the arc plate and fall into the drop port evenly, so that the small and medium-sized particles of waste molding sand are spread on the surface of the vibrating screen frame without gaps. With the operation of the vibrating screen frame, the small and medium-sized particles of waste molding sand are vibrated and screened and magnetically separated, and the separated miscellaneous materials are concentrated and discharged along the miscellaneous material outlet, while the finished molding sand particles on the vibrating screen frame are discharged along the sand material outlet.

[0023] The beneficial effects of the present invention are:

[0024] 1. The present invention uses a coarse material processing mechanism in conjunction with a separation body to form an integrated fine crushing and separation process for the reuse of waste molding sand, effectively improving the multi-step processing of the overall waste molding sand, optimizing the environmental interference, transportation and storage costs, and processing time of the waste molding sand in the multi-step processing, so as to achieve continuous processing of the waste molding sand without gaps and improve the overall processing efficiency;

The molding sand separator capable of realizing gapless operation according to claim 7, characterized in that: An inner worm gear (906) is arranged on the inner wall of the transmission gear disc (904), a ring disc (907) is arranged at the bottom of the inner worm gear (906), a swing rod (908) is sleeved on the surface of the ring disc (907), and a sleeve (909) is arranged below the ring disc (907), a limiting slide rod (910) penetrating the sleeve (909) is sleeved on the bottom of the swing rod (908), and the bottom of the limiting slide rod (910) is connected to the top of the reciprocating connecting rod (902), and the bottom of the reciprocating connecting rod (902) is connected to the sliding beam (801).

9. A method for operating a molding sand separator that realizes gapless operation, used for the molding sand separator that realizes gapless operation according to any one of claims 1 to 7, characterized in that: The following steps are included S1: After the waste molding sand materials generated by the casting process are uniformly recycled, they are continuously transported by relevant transportation equipment and fed into the coarse material processing mechanism (4). They first fall along the feeding frame (402) to the top of the limiting cone rod (403). Some waste molding sand with special shapes or waste molding sand with blocks larger than the gap between the limiting cone rods (403) are intercepted and retained, and the small pieces of waste molding sand that are not intercepted fall to the top of the upper grinding frame (7); S2: Adjacent crushing mechanisms (6) approach each other along the limiting cone rod (403) to push and crush the larger waste sand. When the retaining block (601) is driven by the tension rod (502) to slide along the inner wall of the limiting cone rod (403), a tooth groove is provided on the side of the limiting cone rod (403) and meshes with the outer gear (604). The outer gear (604) meshes with the inner gear (605). The inner gear (605) drives the rotating edge block (602) to rotate through the inner shaft rod (603); S3: The surfaces of the conical groove and the rotating cone (701) are both provided with irregular bumps. The medium-sized particles of waste molding sand entering the conical groove are driven by the rotating cone (701) to roll along the inside of the conical groove. The inflated airbag (703) drives the convex pillar (704) to extend back and forth into the conical groove, so that the medium-sized particles of waste molding sand are disturbed by the bumps, convex pillars (704) and the like during rolling in the rotating cone (701) and the conical groove, thereby forming a multi-stage crushing process to form small and medium-sized particles of waste molding sand. The sliding beam (801) drives the movable cone plate (802) to move up and down between the fixed cone plates (803), so that the small and medium-sized particles of waste molding sand entering between the two are crushed by friction; S4: Small and medium-sized particles of waste molding sand continuously fall onto the conveying frame (3), and are transported to the material drop opening (101) by the conveying frame (3). The adjusting shaft rod (201) is connected and adjusted through an external tool, driving the arc plate (202) to rotate along the bottom of the material leveling cover (2), so that the distance between the bottom of the arc plate (202) and one end of the conveying frame (3) can be adjusted, so that the small and medium-sized particles of waste molding sand unevenly accumulated on the conveying frame (3) are scraped off by the arc plate (202) and fall into the material drop opening (101) in an even amount, so that the small and medium-sized particles of waste molding sand are spread on the surface of the vibrating screen frame (102) without gaps. With the operation of the vibrating screen frame (102), the small and medium-sized particles of waste molding sand are vibrated and screened and magnetically separated, and the separated miscellaneous materials are discharged along the miscellaneous material outlet, while the finished molding sand particles on the vibrating screen frame (102) are discharged along the sand material outlet (104).
