Description

Technical Field

[0001] This invention relates to the field of steel slag concrete technology, specifically to a steel slag crushing and processing device and its usage method for steel slag concrete waste. Background Technology

[0002] Steel slag is a waste residue discharged after steelmaking. It is relatively hard and is generally used to replace crushed stone as a base material. It is mixed with a certain amount of blast furnace slag, calcined gypsum, cement clinker and a small amount of activator and ball-milled to produce steel slag cement. In the process of processing steel slag, some larger pieces of steel slag need to be crushed to meet the production requirements.

[0003] Chinese Patent Publication No. CN114433276B discloses a large-block steel slag crushing device. This device uses a conveying system to transport large blocks of steel slag through the feed inlet to the top of a fixed plate. The slag undergoes initial crushing by a crushing component, followed by pushing by a pushing component between clamping plates. A secondary crushing process is then performed by a clamping component. A screen is installed; smaller particles fall through the screen mesh into the crushing cylinder, while larger particles continue to be crushed by the clamping plates until they can pass through the screen mesh. After smaller particles fall into the inner cavity of the crushing cylinder, slag meeting the requirements is discharged directly from the discharge port. Unacceptable slag accumulates in the inner cavity of the crushing cylinder, where it is further crushed by a crushing mechanism to reduce particle size before being discharged through the discharge port. A guide rod is included to prevent slag from clogging the discharge port, thus solving the problem of large blocks of steel slag being unable to be crushed.

[0004] Compared to the steel slag crushing and processing device mentioned above, the following defects also exist: During the crushing process, due to the impact force of crushing, steel slag fragments and other impurities will splash out from the feed inlet, and the generated dust will also easily drift out, causing environmental pollution. At the same time, during the crushing process, steel slag will fall due to its own weight, making it difficult for the crushing equipment to get close and unable to perform fine crushing operations. Summary of the Invention

[0005] The purpose of this invention is to provide a steel slag crushing and processing device and method for steel slag concrete waste, which solves the following technical problems: During the crushing process, steel slag is subjected to the impact force of crushing, which causes steel slag fragments and other impurities to splash out from the feed inlet, and the generated dust is also very easy to drift out, causing environmental pollution. At the same time, during the crushing process, steel slag falls due to its own weight, making it difficult for the crushing equipment to get close and making fine crushing operation impossible.

[0006] The objective of this invention can be achieved through the following technical solutions: A steel slag concrete waste crushing and processing device includes a fixed housing, with side support brackets fixedly installed on the lower sides of both the left and right ends of the fixed housing, a bottom support frame installed at the lower end of the fixed housing, a discharge hopper connected to the fixed housing provided on the inner side of the side support brackets, a dropping hopper provided at the upper end of the fixed housing, a crushing mechanism provided on the inner side of the fixed housing, and a filtering mechanism provided on the upper rear end of the fixed housing.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-7 As shown, the present invention is a steel slag crushing and processing device and its usage method for steel slag concrete waste.

[0022] Example 1

[0023] Please see Figures 1-7 The present invention relates to a steel slag concrete waste steel slag crushing and processing device, comprising a fixed housing 1, side support brackets 2 fixedly installed on the lower sides of both the left and right ends of the fixed housing 1, a bottom support frame 3 installed at the lower end of the fixed housing 1, a discharge hopper 4 connected to the fixed housing 1 provided on the inner side of the side support brackets 2, a dropping hopper 5 provided at the upper end of the fixed housing 1, a crushing mechanism 6 provided on the inner side of the fixed housing 1, and a filtering mechanism 7 provided on the upper rear end of the fixed housing 1.

[0024] Example 2

[0025] Based on Example 1, a method for using steel slag concrete waste pulverized steel slag includes the following steps: Step 1: Steel slag concrete waste is fed from the hopper 5 into the fixed housing 1, and is diverted and guided by the guide plate 705 and the diversion plate 707. Step 2: Use crushing mechanism 6 to crush the steel slag concrete waste, so that the steel slag concrete can be finely pulverized. Step 3: At the same time, the dust generated during the crushing and pulverizing process is filtered using the filtration mechanism 7 and then discharged to the outside; Step 4: Finally, the crushed steel slag concrete waste will be filtered through metal screen 607 and discharged from hopper 4.

[0026] Example 3

[0027] Please see Figures 1-3 , Figure 5 and Figure 6 In this invention, a technical solution is provided: the crushing mechanism 6 includes crushing hammers 606 arranged in a ring at intervals inside the fixed housing 1. The longitudinal section of the fixed housing 1 is an inverted triangle. Metal screens 607 are installed at the bottom of both sides of the fixed housing 1. The bottom of the metal screens 607 corresponds to the top of the discharge hopper 4. By setting the fixed housing 1 in an inverted triangle structure, the steel slag can fall more effectively.

[0028] The crushing mechanism 6 also includes a first internal tooth adjusting belt 602. An adjusting shaft 603 is provided on the inner side of the upper end of the first internal tooth adjusting belt 602, and a second internal tooth adjusting belt 604 is provided on the outer side of the adjusting shaft 603. A linkage shaft 605 located inside the fixed housing 1 is provided at the rear end of the second internal tooth adjusting belt 604. The first internal tooth adjusting belt 602 and the second internal tooth adjusting belt 604 are both connected to the adjusting shaft 603 by meshing. The adjusting shaft 603 passes through the rear end of the fixed housing 1 and extends to the front end, forming a rotating structure at the front end of the fixed housing 1 through an internal bearing. Since the first internal tooth adjusting belt 602 and the second internal tooth adjusting belt 604 are both meshed with the adjusting shaft 603, when the servo motor 601 is turned on to rotate the first internal tooth adjusting belt 602, the adjusting shaft 603 drives the breaker hammer 606 inside the fixed housing 1 to rotate synchronously.

[0029] The hydraulic breakers 606 are arranged in an alternating manner, with the outer end surface of each hydraulic breaker 606 fitting snugly against the corner of the inner wall of the fixed housing 1, so that the steel slag can be crushed by the impact of the hydraulic breaker 606 during the fall.

[0030] Specifically, steel slag is first fed into the hopper 5, and then, under the diversion of the guide plate 705 and the diverting plate 707, it falls from the left and right sides into the fixed housing 1. At this time, the servo motor 601 is turned to rotate the first internal tooth adjusting belt 602. Since the first internal tooth adjusting belt 602 and the second internal tooth adjusting belt 604 are both connected to the adjusting shaft 603 by meshing, they can drive the adjusting shaft 603 and the linkage shaft 605 connected to its rear end to rotate synchronously, thereby causing the breaker hammer 606 to rotate alternately in the fixed housing 1 to crush the steel slag. The outer surface of the breaker 606 is fitted to the three corners of the inner wall of the fixed housing 1. When the steel slag falls to the bottom, it can be lifted up by the action of the breaker 606 to continue crushing. After reaching the size of the crushed particles, they can enter the discharge hopper 4 through the metal screen 607 and be discharged uniformly. The first adjusting bolt 608 and the rubber ring 609 are connected by a sleeve. The first adjusting bolt 608 passes through the discharge hopper 4 and the side support bracket 2 in a threaded connection, which can make the discharge hopper 4 stably installed on the side support bracket 2 and facilitate disassembly and cleaning in the future.

[0031] Example 4

[0032] Please see Figures 1-7 In this invention, a technical solution is provided: the filtration mechanism 7 includes guide plates 705 disposed on the upper left and right sides inside the hopper 5, a baffle curtain 706 disposed at the lower end of the guide plate 705, and a diversion plate 707 connected to the fixed housing 1 disposed on the inner side of the baffle curtain 706; the width between the bottom end of the guide plate 705 and the diversion plate 707 is equal to the width between the bottom end of the diversion plate 707 and the inner wall of the hopper 5, which can prevent the steel slag from clogging at the hopper 5; Two sets of blocking curtains 706 are provided below the guide plate 705. The blocking curtains 706 are parallel to each other below the guide plate 705. The bottom end of the blocking curtains 706 contacts the upper surface of the diversion plate 707. The two sets of blocking curtains 706 can effectively block the smoke and dust, preventing the smoke and dust from drifting upward along the gap between the blocking curtains 706 and the diversion plate 707.

[0033] The filtration mechanism 7 also includes a filter housing 701. The upper side of the filter housing 701 is provided with a filter washing liquid 708. A flow cavity 709 is opened on the inner side of the rear end of the filter housing 701. A filter screen 710 is provided on the lower side of the filter housing 701. The mesh size of the filter screen 710 is arranged to increase from top to bottom, so that the gas without dust can be discharged outward through the layer filtration of the filter washing liquid 708 and the filter screen 710.

[0034] Specifically, the filter box 701 is fixedly installed on the upper rear end of the fixed housing 1 via the second adjusting bolt 702, and connected to the discharge hopper 5 via the air inlet pipe 704. During the steel slag crushing process, a large amount of smoke and dust will be generated. Two sets of baffle curtains 706 are installed below the guide plate 705. The baffle curtains 706 are parallel to each other below the guide plate 705, and the bottom end of the baffle curtains 706 contacts the upper surface of the diversion plate 707. The two sets of baffle curtains 706 can effectively block the smoke and dust, preventing smoke from entering the house. Dust drifts upwards along the gap between the baffle curtain 706 and the diverter plate 707. At this time, the fan 703 is turned on to draw smoke and dust into the filter box 701 through the air inlet pipe 704. After being filtered by the filter washing liquid 708, the dust is discharged to the lower rear end through the flow cavity 709. Because the mesh size of the filter screen 710 is set to increase from top to bottom, the gas is filtered again. Finally, it is discharged to the outside through the exhaust hole 711 to achieve the purification effect and avoid environmental pollution and harm to the health of the staff.

[0035] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
