Description

Technical Field

[0001] This utility model belongs to the field of slag treatment technology, specifically relating to a screening device for screening slag. Background Technology

[0002] Slag is a solid waste produced after ore beneficiation or smelting. During beneficiation, the ore undergoes a series of processes such as crushing and grinding, separating out some useless components to form slag. For example, in copper ore beneficiation, gangue minerals (such as quartz) are removed through processes like flotation, and these gangue minerals become part of the slag. In smelting, the remaining material after the metals in the ore are extracted is also slag. Taking iron smelting as an example, after the iron in iron ore is reduced, the remaining blast furnace slag mainly contains calcium oxide, silicon dioxide, and aluminum oxide.

[0003] Traditional screening equipment often suffers from low screening efficiency when processing slag. Because slag particles are irregular in shape and have a wide size distribution, different industries have significantly different particle size requirements. For example, the particle size requirements for slag used as an admixture in cement production differ from those for slag used as aggregate in road engineering. Ultimately, some of the screened material contains large, recyclable waste particles, but these large particles are present in small quantities and are not easily processed by large crushing equipment.

[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides a screening device for screening slag, comprising,

[0027] The screening assembly 100 includes a housing 101, a screen plate 102 installed inside the housing 101, a hopper 103 installed at the feed inlet of the housing 101, and a guide plate 104 installed in the middle of the housing 101.

[0028] The feeding assembly 200 includes a hopper 201 installed at the end of the housing 101, a roller 202 rotatably installed in the middle of the hopper 201, a rotating shaft 203 rotatably installed on one side inside the hopper 201, and a toothed plate 204 installed on the side wall of the rotating shaft 203. The side wall of the roller 202 is in rotatable contact with the toothed plate 204, and the end of the guide plate 104 is inserted into the center of the roller 202.

[0029] The screening component 100 is used for preliminary screening of the waste residue. The hopper 103 is used to guide the waste residue into the box 101. The waste residue is screened by the screen plate 102. Small particles of waste residue are screened out from below the guide plate 104, while large particles of waste residue enter the hopper 201 from the guide plate 104. The control device drives the drum 202 to rotate. The drum 202 can further screen the waste residue. Larger particles of waste residue are discharged from the end of the drum 202. Then, the waste residue is transferred to the upper end of the toothed plate 204 set on the side wall of the drum 202, which drives the rotating shaft 203 to rotate. The rotating shaft 203 can drive the toothed plate 204 to rotate synchronously, thereby moving the material and bringing the material close to the side wall of the drum 202. Continued rotation will crush the large particles of waste residue, further crushing the waste residue.

[0030] Specifically, the screening assembly 100 also includes a first motor 105 installed on the side wall of the sieve plate 102, and an eccentric wheel 106 adapted to be installed at the output end of the first motor 105.

[0031] In this design, a first motor 105 with an eccentric wheel 106 is added to the side wall of the screen plate 102. The first motor 105 is driven by a control device to run. The first motor 105 drives the eccentric wheel 106 to rotate. When the eccentric wheel 106 runs, it applies a periodic tension or pressure to the connected screen plate 102, causing the screen plate 102 to vibrate according to the rotation frequency of the eccentric wheel 106, thereby improving the screening efficiency of waste residue.

[0032] Furthermore, the screening assembly 100 also includes a cover plate 107 installed on the side wall of the screen plate 102, the cover plate 107 being snapped onto the outside of the first motor 105.

[0033] Among them, a cover plate 107 is installed on the side wall of the screen plate 102. The cover plate 107 is used to shield and protect the first motor 105 and the eccentric wheel 106, reduce the impact of slag on the vibrating components, and maintain the stable operation of the first motor 105 with the eccentric wheel 106 installed.

[0034] Furthermore, the feeding assembly 200 also includes a conveyor belt 205 installed on the inner side of the lower end of the hopper 201, with the end of the conveyor belt 205 extending below the guide plate 104.

[0035] Among them, a conveyor belt 205 is added to the bottom of the silo 201. The conveyor belt 205 is used to transport small particles of waste residue backward and separate them from large particles of waste residue for processing.

[0036] Preferably, the feeding assembly 200 also includes a feed inlet 206 disposed on the side wall of the roller 202, the feed inlet 206 being used in conjunction with the toothed plate 204.

[0037] The roller 202 has a feed inlet 206 on its side wall. The feed inlet 206 is used to feed the material and facilitate the screening of large particles of waste residue. Smaller particles of waste residue are discharged from the feed inlet 206 at the bottom of the roller 202. It also facilitates the collection of waste residue crushed by the toothed plate 204 and the roller 202.

[0038] It should be noted that the feeding assembly 200 also includes a main gear 207 installed at the main shaft end of the roller 202, and a secondary gear 208 adapted to be installed at the end of the rotating shaft 203, wherein the main gear 207 and the secondary gear 208 mesh.

[0039] Among them, a main gear 207 and a secondary gear 208 are installed at the ends of the drum 202 and the rotating shaft 203. When the drum 202 rotates, it can drive the rotating shaft 203 to rotate synchronously, thereby pushing the material placed on the upper end of the toothed plate 204 toward the side wall of the drum 202. The material is crushed by the side wall of the drum 202, thus improving the waste residue treatment efficiency.

[0040] Preferably, the feeding assembly 200 further includes a second motor 209 fixedly installed on the outside of the hopper 201, a main pulley 210 installed on the main shaft end of the second motor 209, and a secondary pulley 211 installed on the main shaft end of the roller 202. It also includes a belt 212 installed on the outside of the main pulley 210 and the secondary pulley 211, and the main pulley 210 and the secondary pulley 211 are connected by belt 212.

[0041] A second motor 209 is installed on the outer wall of the silo 201. When the second motor 209 is running, it will drive the auxiliary pulley 211 through the main pulley 210 and the belt 212, thereby driving the drum 202 to rotate and further screen large particles of waste residue.

[0042] In operation, waste residue is fed into hopper 103. Inside housing 101, the waste residue is screened by screen plate 102. Control equipment drives first motor 105, which in turn drives eccentric wheel 106. During operation, eccentric wheel 106 applies periodic tension or pressure to the connected screen plate 102, forcing it to vibrate at the rotational frequency of eccentric wheel 106, thus improving the screening efficiency. Small particles of waste residue are screened out from below guide plate 104, while larger particles enter hopper 201 from guide plate 104. Control equipment then drives second motor 209, which, along with the main belt,... Wheel 210, in conjunction with belt 212, drives auxiliary pulley 211 to run, which in turn drives drum 202 to rotate. Drum 202 further screens large particles of waste residue. Larger particles of waste residue are discharged from the end of drum 202 and then transferred to the upper end of toothed plate 204 on the side wall of drum 202, driving shaft 203 to rotate. Shaft 203 drives toothed plate 204 to rotate synchronously, thereby moving the material and bringing it close to the side wall of drum 202. Continued rotation will crush the large particles of waste residue, further crushing the waste residue. Conveyor belt 205 is used to collect small particles of waste residue and transport them backward, separating them from the large particles of waste residue for processing.

[0043] In summary, the combined use of the screening component 100 and the feeding component 200 can effectively separate slag of different particle sizes, allowing the slag particles to be graded and screened according to the predetermined screen aperture size of the screen plate. This meets the requirements of various subsequent processing or applications for slag particle size, improves screening speed and output, reduces the time cost of screening operations, and allows for further separation and recovery of useful components in the slag through screening, maximizing resource utilization. At the same time, it facilitates the recycling and crushing of large-particle waste slag without requiring it to go through specialized crushing equipment again, reducing the operating costs of large crushing equipment.
