Description

Technical Field

[0001] This utility model relates to the field of foundry sand treatment technology, and in particular to a sand clump crushing and screening device. Background Technology

[0002] The casting process requires a large amount of molding sand. Reusing molding sand can reduce its consumption and effectively lower casting costs. However, after use, the molding sand is recycled in clumps and needs to be crushed before it can be reused. Since casting has requirements on the mesh size of molding sand, it must be crushed to a certain particle size before it can be reused. Molding sand that does not meet the requirements needs to be crushed and screened again. In addition, there is a certain amount of casting slag in the sand clumps. If it is not removed, it will affect the quality of the castings in the next casting. Utility Model Content

[0006] Furthermore, it also includes a collection tank, the height of which is less than the distance between the fixed plate and the screen of the screening component.

[0007] Furthermore, it also includes an automatic telescopic rod, which is connected to the upper side of the lifting platform and drives the lifting platform to rise and fall.

[0008] Furthermore, a number of guide rods are connected to the upper side of the fixed plate, and the guide rods slide through the lifting plate.

[0009] Furthermore, the inlet of the lifting component is connected to a hopper, and the coarse material outlet of the screening component is located above the hopper.

[0010] Furthermore, it also includes a storage cylinder for storing sand pellets, with the inlet of the storage cylinder corresponding to the outlet of the lifting component; the lower end of the storage cylinder is connected to a screw conveyor component, and the output end of the screw conveyor component is connected to the crushing component.

[0022] The present invention will be further described in detail below with reference to the embodiments.

[0023] Specific embodiments of the sand crushing and screening device provided by this utility model:

[0024] Please see Figure 1-3 The sand agglomeration crushing and screening device includes a lifting component 1, a crushing component 2 and a screening component 3; the lifting component 1 lifts the sand agglomeration, the crushing component 2 crushes the lifted sand agglomeration, and the screening component 3 screens the crushed sand; the coarse material outlet of the screening component 3 corresponds to the inlet of the lifting component 1.

[0025] In this embodiment, the lifting component 1 is a bucket elevator, and the inlet of the lifting component 1 is connected to the hopper 5. The screening component 3 has a single-layer screen, and the upper part of the screen is connected to a coarse material outlet. The coarse material outlet of the screening component 3 is located above the hopper 5, and the molding sand that does not meet the requirements re-enters the lifting component 1; the lower part of the screen has a fine material outlet, and a conveyor can be set below the fine material outlet to transport the molding sand that meets the requirements.

[0026] In this embodiment, a storage cylinder 6 for storing sand agglomerates is provided, with the inlet of the storage cylinder 6 corresponding to the outlet of the lifting component 1; the lifting component 1 guides the lifted sand agglomerates into the storage cylinder 6 for temporary storage. A screw conveyor component 8 is connected to the lower end of the storage cylinder 6, and the output end of the screw conveyor component 8 is connected to the crushing component 2.

[0027] The crushing component 2 is located above one end of the screen of the screening component 3. After the crushing component 2 crushes the sand clumps, the crushed sand falls onto the upper part of the screen for screening. The screw conveyor component 8, the crushing component 2, and the screening component 3 are all commonly used equipment, and their specific structures will not be described in detail in this embodiment.

[0028] In this embodiment, the storage cylinder 6 is symmetrically provided with supports 7 on both sides.

[0029] The screening component 3 is equipped with a magnetic suction component 4 for adsorbing iron slag. The magnetic suction component 4 includes a lifting plate 42 and a fixing plate 41. The fixing plate 41 is a non-magnetic plate and is fixed between the supports 7. The middle part of the fixing plate 41 is located on the upper side of the screen and has a gap with the screen.

[0030] The lifting plate 42 is located between the brackets 7 on the upper side of the fixed plate 41. A permanent magnet plate 43, which is a high-strength permanent magnet plate, is connected to the lower side of the lifting plate 42. Automatic telescopic rods 45 are provided on the inner side of the brackets 7. The automatic telescopic rods 45 can be hydraulic or electric. The telescopic end of the automatic telescopic rod 45 is connected to the upper side of the end of the lifting plate 42. The extension and retraction of the telescopic end of the automatic telescopic rod 45 can drive the lifting plate 42 to rise and fall.

[0031] Several vertical guide rods 46 are connected to the upper side of the end of the fixed plate 41. In this embodiment, there are four guide rods 46. The guide rods 46 slide through the lifting plate 42, and the guide rods 46 make the lifting plate 42 rise and fall vertically in a stable manner.

[0032] When the lifting plate 42 moves down, it adheres to the upper side of the fixed plate 41. During the screening process of the screening component 3, the iron slag and large particles of molding sand jump and move on the upper side of the screen. The permanent magnet plate 43 attracts the iron slag and adsorbs it onto the lower side of the fixed plate 41.

[0033] In this embodiment, an independent collection trough 44 is provided, the height of which is less than the distance between the fixed plate 41 and the screen of the screening component 3. When the iron slag under the fixed plate 41 is full, the lifting component 1, the screw conveyor component 8, the crushing component 2, and the screening component 3 stop working. The collection trough 44 is placed on the upper part of the screen under the fixed plate 41. Then, the automatic telescopic rod 45 drives the lifting plate 42 and the permanent magnet plate 43 to move upward and away from the fixed plate 41. The fixed plate 41 can no longer adsorb the iron slag, and the iron slag falls into the collection trough 44, thus realizing the collection of iron slag.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
