Description

Technical Field

[0001] This utility model relates to the technical field of slag treatment equipment, specifically a slag recycling and crushing device with a sorting auxiliary structure. Background Technology

[0002] With the rapid development of industry, the amount of slag produced by various industrial furnaces and kilns has increased dramatically. Slag usually contains a variety of valuable components, such as metals like iron, copper, and zinc, as well as some minerals that can be used in building materials. If these slags are not properly treated and are directly discarded, it will not only lead to a huge waste of resources, but also cause serious damage to the ecological environment as harmful substances in the slag seep into the soil and water.

[0003] Traditional slag treatment methods are mostly simple and crude, usually involving only preliminary crushing followed by landfilling or stockpiling. During the slag recycling process, the uneven particle size distribution of the slag itself further affects the crushing effect and the accuracy of subsequent sorting, resulting in poor overall slag recycling process. Moreover, existing slag crushing equipment is prone to frequent blockages in the feeding section due to the different particle sizes, affecting the operating efficiency of the recycling equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a slag recycling and crushing device with a sorting auxiliary structure to solve the problem mentioned in the background art that the uneven particle size distribution of slag itself further affects the crushing effect and the accuracy of subsequent sorting, resulting in poor effect of the entire slag recycling process. In addition, the existing slag crushing device is prone to frequent blockage in the feeding part during operation due to different particle sizes, which affects the operating efficiency of the recycling device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a slag recycling and crushing device with a sorting auxiliary structure, including a crushing box, which is configured as a rectangular box structure, wherein a four-axis crushing drive assembly is installed inside the crushing box, and the four-axis crushing drive assembly and the crushing box constitute the main crushing device for slag crushing.

[0006] The opening on the crushing box is engaged with the bottom of the mounting cover, and the upper end of the mounting cover has two annular protrusions, which are engaged with the first and second sorting cylinders respectively.

[0007] An inclined screening plate is installed inside the first sorting cylinder, and the upper surface of the inclined screening plate is set as an inclined surface. The bottom end of the inclined screening plate is inserted into one side of the diversion pipe, and the diversion pipe connects the first sorting cylinder and the second sorting cylinder. An air bladder column is slidably connected inside the diversion pipe, and the bottom end of the inner wall of the diversion pipe is set as an inclined surface.

[0008] A metal plate fixedly connected to the lifting column is installed in the upper opening of the second sorting cylinder. The output end of the lifting column is threadedly connected to the crushing plate, and the bottom end of the crushing plate is engaged with the positioning crushing plate. An intercepting plate is installed at the bottom end of the positioning crushing plate, and a positioning ring is engaged at the bottom end of the intercepting plate. The positioning ring abuts against the annular protrusion of the mounting cover.

[0009] By adopting the above technical solution, the sorting and preliminary crushing operations of the slag before crushing make the entire slag processing flow more continuous, reduce the transfer links, and improve processing efficiency.

[0010] Preferably, a sealing element is provided at the connection between the mounting cover and the first and second sorting cylinders, and the diameter of the second sorting cylinder is larger than the diameter of the first sorting cylinder.

[0011] By adopting the above technical solution, the different diameters of the sorting cylinders make the flow and processing space of slag within the device more reasonable, which is conducive to sorting and crushing operations at different stages and improves the overall operational stability of the equipment.

[0012] Preferably, the upper end of the sorting cylinder is engaged with the bottom hole of the guide bucket, and a grid plate is engaged with the upper end of the guide bucket.

[0013] By adopting the above technical solution, the guide bucket is precisely connected to the first sorting cylinder, so that the slag can enter the first sorting cylinder accurately and smoothly, ensuring the normal start-up and continuous operation of the sorting process.

[0014] Preferably, the highest point of the diversion pipe slope abuts against the lowest point of the slope of the inclined screening plate, and the lowest point of the diversion pipe slope is above the positioning crushing plate.

[0015] With the above technical solution, the bottom of the inclined surface of the diversion pipe is above the positioning crushing plate, so that the slag flows naturally into the crushing area of ​​the second sorting cylinder under the action of gravity, ensuring smooth material flow and reducing the occurrence of blockage.

[0016] Preferably, the airbag column is composed of a rectangular corrugated tube and an arc-shaped plate, and the arc-shaped plate of the airbag column is slidably connected to the diversion pipe. The inner cavity of the corrugated tube of the airbag column is connected to the output end of the air pump, and the air pump is installed at the upper end of the diversion pipe.

[0017] Using the above technical solution, the air pump controls the expansion and contraction of the air bladder column, which can accurately determine whether the slag enters the diversion pipe, and thus control the timing of the slag entering the second sorting cylinder.

[0018] Preferably, the positioning crushing plate is configured as an annular shape, and the contact surface between the positioning crushing plate and the extrusion crushing plate is configured as an inclined surface, and the extrusion crushing plate is configured as a frustum structure.

[0019] By adopting the above technical solution, the frustum structure of the extrusion crushing plate and the annular structure of the positioning crushing plate are combined to concentrate the crushing of slag in a specific area, ensuring more uniform crushing.

[0020] Preferably, the interceptor plate is configured as a ring structure, and a fence structure is provided in the central opening of the interceptor plate, and the opening diameter of the interceptor plate is consistent with the opening diameter of the bottom end of the positioning and breaking plate.

[0021] By adopting the above technical solution, the ring structure and fence design of the interceptor plate can effectively intercept the slag particles that are still relatively large after being crushed and squeezed, preventing them from entering the subsequent equipment and avoiding equipment jamming or damage.

[0022] Compared with the prior art, the beneficial effects of this utility model are: the slag recycling and crushing device equipped with a sorting auxiliary structure:

[0023] 1. When processing slag, this device initially intercepts large-sized impurities through the upper grid plate of the guide bucket, ensuring that the slag entering the device is of appropriate size. Then, the slag is made to slide down the inclined screen plate set in the first sorting cylinder by gravity. Smaller slag particles can fall directly into the crushing box through the screen holes. As the diversion pipe connects the first sorting cylinder and the second sorting cylinder, the air pump controls the expansion and contraction of the air bladder column, precisely controlling whether the slag enters the diversion pipe and determining the timing of the slag entering the second sorting cylinder. This ensures that the slag on the inclined screen plate is fully screened, improves the sorting accuracy, and thus achieves particle size classification and screening, improves the targeting of subsequent crushing, reduces equipment energy consumption, and improves the overall processing efficiency.

[0024] 2. In the second sorting cylinder, the lifting column drives the extrusion crushing plate to move up and down, cooperating with the positioning crushing plate. The extrusion force generated by the inclined contact of the two effectively crushes the slag, so that the slag is concentrated and crushed in a specific area. The small-particle slag screened out by the first sorting cylinder and the slag crushed by the second sorting cylinder both enter the crushing box for further crushing by the four-axis crushing drive component. Through the multi-stage crushing collaborative working mode, the slag can be finely crushed in multiple rounds to achieve the desired particle size. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6 This utility model provides a technical solution: a slag recycling and crushing device with a sorting auxiliary structure, including a crushing box 1, a four-axis crushing drive assembly 2, a mounting cover 3, a sorting cylinder 1 4, a guide bucket 5, an inclined screening plate 6, a diversion pipe 7, an airbag column 8, an air pump 9, a sorting cylinder 2 10, a lifting column 11, a compression crushing plate 12, a positioning crushing plate 13, an interception plate 14, and a positioning ring 15;

[0034] Among them, the crushing box 1 is configured as a rectangular box structure. The crushing box 1 is equipped with a four-axis crushing drive assembly 2, and the four-axis crushing drive assembly 2 and the crushing box 1 constitute the main crushing device for slag crushing.

[0035] The opening on the crushing box 1 is engaged with the bottom of the mounting cover 3, and the upper end of the mounting cover 3 has two annular protrusions. The two annular protrusions of the mounting cover 3 are engaged with the first separation cylinder 4 and the second separation cylinder 10 respectively. A sealing element is provided at the connection between the mounting cover 3 and the first separation cylinder 4 and the second separation cylinder 10. The diameter of the second separation cylinder 10 is larger than the diameter of the first separation cylinder 4. The upper end of the first separation cylinder 4 is engaged with the bottom round hole of the guide bucket 5, and a grid plate is engaged with the upper end of the guide bucket 5.

[0036] An inclined screening plate 6 is installed inside the first sorting cylinder 4, and the upper surface of the inclined screening plate 6 is set as an inclined surface. The bottom end of the inclined surface of the inclined screening plate 6 is inserted into one side of the diversion pipe 7, and the diversion pipe 7 connects the first sorting cylinder 4 and the second sorting cylinder 10. An airbag column 8 is slidably connected inside the diversion pipe 7, and the bottom end of the inner wall of the diversion pipe 7 is set as an inclined surface. The highest point of the inclined surface of the diversion pipe 7 abuts against the lowest point of the inclined surface of the inclined screening plate 6, and the lowest point of the inclined surface of the diversion pipe 7 is above the positioning crushing plate 13. The airbag column 8 is composed of a rectangular corrugated pipe and an arc plate, and the arc plate of the airbag column 8 is slidably connected to the diversion pipe 7. The inner cavity of the corrugated pipe of the airbag column 8 is connected to the output end of the air pump 9, and the air pump 9 is installed at the upper end of the diversion pipe 7.

[0037] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the crushing device, consisting of crushing box 1 and four-axis crushing drive assembly 2, is installed in a designated area. The drive motor of the four-axis crushing drive assembly 2 is driven to rotate via a coupling. During operation, the crushing teeth on different shafts interlock and mesh. Due to the differences in rotational speed and direction of each shaft, multiple shearing, compressive, and impact forces are provided to the slag entering the crushing box 1, achieving powerful crushing of the slag. The mounting cover 3 is coated with sealant and tightly fitted into the crushing box 1 to ensure the internal sealing of the device and prevent dust leakage. The sorting cylinders 1-4 and 2-10 are engaged on the annular protrusion of the mounting cover 3 and reinforced. Figure 1-2 As shown, during operation, the guide bucket 5 guides the slag into the sorting cylinder 4. The slag slides down the inclined screen plate 6 under gravity. Smaller slag particles fall into the crushing box 1 through the screen holes and are crushed by the four-axis crushing drive assembly 2. Larger slag particles slide down to the bottom of the inclined surface. The air bladder column 8 in the diversion pipe 7, under the action of the air pump 9, controls whether the slag enters the diversion pipe 7 by expanding or contracting, thereby determining whether the slag can enter the sorting cylinder 10.

[0038] In this system, an airbag column 8 is installed inside the diversion pipe 7 and connected to an air pump 9. The output end of the air pump 9 is connected to the corrugated inner chamber of the airbag column 8 through an air pipe. As the air pump 9 inflates, the corrugated tube of the airbag column 8 expands, allowing the arc plate of the airbag column 8 to slide smoothly inside the diversion pipe 7. At this time, under the action of the air pump 9, the airbag column 8 inside the diversion pipe 7 controls whether the slag enters the diversion pipe 7 by expanding or contracting, thereby determining whether the slag can enter the sorting cylinder 10.

[0039] A metal plate fixedly connected to the lifting column 11 is installed in the upper opening of the sorting cylinder 10. The output end of the lifting column 11 is threadedly connected to the crushing plate 12, and the bottom end of the crushing plate 12 is engaged with the positioning crushing plate 13. An intercepting plate 14 is installed at the bottom end of the positioning crushing plate 13, and a positioning ring 15 is engaged at the bottom end of the intercepting plate 14. The positioning ring 15 abuts against the annular protrusion of the mounting cover 3. The positioning crushing plate 13 is annular, and the contact surface between the positioning crushing plate 13 and the crushing plate 12 is inclined. The crushing plate 12 is a frustum structure, and the intercepting plate 14 is annular. A fence structure is provided in the central opening of the intercepting plate 14, and the opening diameter of the intercepting plate 14 is the same as the opening diameter at the bottom end of the positioning crushing plate 13.

[0040] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the slag passing through the diversion pipe 7 enters the sorting cylinder 10. Since the output end of the lifting column 11 is threadedly connected to the crushing plate 12, and the lifting column 11 is a two-section slidingly connected rod, the lifting column 11 drives the crushing plate 12 to be pushed so that it is tightly engaged with the bottom end of the positioning crushing plate 13. During operation, the lifting column 11 drives the crushing plate 12 to rise and fall, cooperating with the positioning crushing plate 13 to crush the slag entering the sorting cylinder 10. After crushing, larger particles of slag are intercepted by the grid structure of the interception plate 14, while smaller particles fall into the crushing box 1 through the opening and are crushed again by the four-axis crushing drive assembly 2. This cycle is repeated to realize the continuous recycling and crushing of slag by the device. The frustum structure of the crushing plate 12 and the annular structure of the positioning crushing plate 13 cooperate to concentrate the crushing of slag in a specific area, ensuring more uniform crushing. The opening diameter of the interception plate 14 is the same as the opening diameter of the bottom end of the positioning crushing plate 13, thereby ensuring that small particles of slag pass through smoothly and maintaining the smooth operation of the equipment.

[0041] Working Principle: When using this slag recycling and crushing device equipped with a sorting auxiliary structure, the mounting cover 3 is installed on the crushing box 1. The four-axis crushing drive assembly 2 inside the crushing box 1 is connected to the power system and control system in the working area. The slag to be processed is sent into the guide hopper 5 through the transport equipment. The grid plate at the upper end of the guide hopper 5 initially intercepts larger lumps of impurities, ensuring that the size of the slag entering the device is within a suitable range. The inclined screening plate 6 inside the sorting cylinder 1 4 has an inclined end face, allowing the slag to slide down the inclined screening plate 6 under the action of gravity. During this process, smaller particles of slag will fall directly into the crushing box 1 through the screen holes on the inclined screening plate 6 and be crushed by the four-axis crushing drive assembly 2. Larger particles of slag that cannot pass through the screening continue to slide down the inclined surface to the bottom of the inclined surface and enter the sorting cylinder 2 10 through the inclined surface at the bottom of the diversion pipe 7. When the slag reaches the diversion pipe 7, the air bladder column 8 inside the diversion pipe 7 is inflated by the air pump 9 or deflated by the air pump 9, thereby changing the size of the space inside the diversion pipe 7 and thus blocking the slag. The flow rate is affected by the slope of the diversion pipe 7, which facilitates the slag to enter the sorting cylinder 10 under gravity. After being pushed up and down by the output end of the lifting column 11, the compression crushing plate 12 is closed with the positioning crushing plate 13, thereby achieving the compression crushing of the slag. The positioning crushing plate 13 plays a role in positioning and assisting crushing, so that the slag is crushed more effectively in a specific area. After compression crushing, larger particles of the slag will be intercepted by the grid structure of the interception plate 14, while smaller particles can fall through the opening into the crushing box 1, where they are crushed by the four-axis crushing drive assembly 2. The four-axis crushing drive assembly 2 consists of four cooperating shafts, which rotate under the power transmitted by the drive motor through the coupling. During this process, the crushing teeth on different shafts interlock and mesh with each other. Due to the differences in the rotation speed and direction of each shaft, the slag will be subjected to shearing force, extrusion force and impact force from multiple directions, thereby achieving further crushing of the slag and increasing the overall practicality.

[0042] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
