Description

Technical Field

[0001] The invention relates to the technical field of waste slag and steel slag treatment, in particular to an industrial waste slag and steel slag treatment device. Background Art

[0002] Steel slag is a byproduct of the steelmaking process. It is composed of various oxides formed by the oxidation of impurities such as silicon, manganese, phosphorus, and sulfur in pig iron during the smelting process, as well as salts generated by the reaction of these oxides with solvents. There are two main ways to comprehensively utilize steel slag as a secondary resource. One is to recycle it in the factory as a smelting solvent, which can not only replace limestone, but also recover a large amount of metallic iron and other useful elements. The other is to use it as a raw material for manufacturing road construction materials, building materials or agricultural fertilizers. When processing industrial waste steel slag, due to the different sizes of waste steel slag, it is necessary to use a vertical sand making machine to crush the material so that its size reaches the recycling standard before it can be used.

[0003] However, when the existing vertical sand making machine is in use, due to the high hardness of waste slag and steel slag, the material may not be completely crushed in the crushing chamber, resulting in uneven discharge, and the crushed material is directly discharged to the ground through the lower hopper. Some materials have different volumes, and direct recycling may easily affect the use effect of the materials; since the materials are accumulated at the bottom of the sand making machine, the work efficiency is low when tools are used to manually shovel the materials; turning the materials will also produce a lot of dust, and the operator is close to the materials, so it is easy to inhale the dust into the mouth and nose, which will cause harm to the operator's body and the surrounding environment.

One of the sleeves is in contact with the sand making machine body, and the limiting block conflicts with the top of the other sleeve.

[0011] The beneficial effects of the present invention are:

[0012] (1) The industrial waste slag and steel slag processing device described in the present invention discharges the waste slag and steel slag into the interior of the main body mechanism, and turning on the control switch of the driving mechanism can drive the crushing mechanism to rotate in the main body mechanism, thereby facilitating the crushing and processing of the waste slag and steel slag, that is: the waste slag and steel slag to be processed can be transported to the upper hopper through the material conveyor. Since the upper hopper is connected to the interior of the sand making machine body and the inner wall of the upper hopper is arranged in an inclined structure, the material can be quickly discharged into the sand making machine body through the upper hopper; when the waste slag and steel slag falls into the sand making machine body, the operator can turn on the control switch of the first motor, the first motor is fixed to the side wall of the mounting frame, and the first motor drives the first rotating wheel to rotate. Since a belt is wound around the first rotating wheel, the belt As the first wheel rotates, it can drive the second wheel to rotate, and the second wheel drives the driving shaft to rotate inside the sand making machine body. The side walls of the driving shaft are sleeved with several sleeves and hammer plates. When the material falls vertically into the interior of the sand making machine body, the material contacts the hammer head installed at the end of the hammer handle, so that the hammer head can hit the material through high-speed rotation to break the material into the required particle size. The crushed material will be discharged from the lower hopper installed at the bottom of the sand making machine body; when the internal components of the sand making machine body need to be inspected, the operator can open the limit assembly of the inspection door, and then rotate the inspection door to make it rotate along the fixed block installed on the side wall of the sand making machine body, thereby making the sand making machine body open, which is convenient for the operator to observe its internal situation.

[0013] (2) The industrial waste slag and steel slag processing device described in the present invention can discharge the waste slag and steel slag into the interior of the screening mechanism after crushing. When the screening mechanism is started, the crushed material can be screened when it slides back and forth, thereby improving the material processing effect. That is, since the lower hopper is located at the center of the filter frame, when it discharges the crushed material into the filter frame, the control switch of the hydraulic rod can be turned on. The hydraulic rod is fixed inside the mounting plate. When the hydraulic rod is started, the telescopic end of the hydraulic rod can drive the slide plate to slide in the limit groove portion provided in the receiving hopper. The limit groove portion is also slidably installed with a slider. The slider and the slide plate are fixedly connected to the side wall of the card frame. The hydraulic rod drives the slide plate to slide, so that the card frame can be displaced along the inner wall of the receiving hopper, and then the slider slides in another limit groove portion. A filter frame is installed in the card frame. The material is screened by the filter frame that slides back and forth, and the material with larger particles can be collected inside the filter frame, thereby facilitating the improvement of the material screening effect.

[0014] (3) The industrial waste slag and steel slag processing device described in the present invention, after the material is screened, it falls to the top of the conveying mechanism. When the conveying mechanism is started, it can convey the screened material out of the interior of the screening mechanism, that is, the screened material will fall through the mesh of the filter frame to the top of the conveyor belt. Since the conveyor belt is close to the bottom end of the receiving hopper, when the control switch of the second motor is started, it can drive the rotating shaft to rotate inside the receiving hopper. A gear is fixedly installed at the end of the rotating shaft away from the second motor. The rotation of the gear drives the chain meshing with it to rotate, and then the chain drives another gear to rotate. The other gear is fixedly connected to the long rod. When the rotating shaft and the long rod rotate inside the receiving hopper, the guide rollers fixed to the side walls of the rotating shaft and the long rod can rotate along the inner wall of the receiving hopper. The conveyor belt is wrapped around the side wall of the guide roller. The rotation of the guide roller can drive the conveyor belt to move, so that it can convey the screened material.

That is, since the lower hopper 305 is located at the center of the filter frame 406, when the crushed material is discharged into the filter frame 406, the control switch of the hydraulic rod 409 can be turned on. The hydraulic rod 409 is fixed inside the mounting plate 401. When the hydraulic rod 409 is started, the telescopic end of the hydraulic rod 409 can drive the slide plate 410 to move in the limit groove 40 provided in the receiving hopper 403. 8, a slider 407 is also slidably installed at the limiting groove 408, the slider 407 and the slide plate 410 are fixedly connected to the side wall of the card frame 405, and the hydraulic rod 409 drives the slide plate 410 to slide, so that the card frame 405 can be displaced along the inner wall of the receiving hopper 403, and then the slider 407 can slide at another limiting groove 408. A filter frame 406 is installed in the card frame 405. The material is screened by the filter frame 406 that slides back and forth, and the material with larger particles can be collected inside the filter frame 406, so as to improve the screening effect of the material.

[0031] Specifically, Figure 1 , Figure 2 , Figure 5 , Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, the conveying mechanism 5 includes a second motor 501 and a rotating shaft 503.

Starting the conveying mechanism 5 can enable it to convey the screened material out of the interior of the screening mechanism 4, that is, the screened material will pass through The mesh of the filter frame 406 falls to the top of the conveyor belt 502. Since the conveyor belt 502 is close to the bottom of the receiving hopper 403, when the control switch of the second motor 501 is started, it can drive the rotating shaft 503 to rotate inside the receiving hopper 403. A gear 506 is fixedly installed on the end of the rotating shaft 503 away from the second motor 501. The rotation of the gear 506 drives the chain 507 meshing with it to rotate, and then the chain 507 drives another gear 506 to rotate. The other gear 506 is fixedly connected to the long rod 504. When the rotating shaft 503 and the long rod 504 both rotate inside the receiving hopper 403, the guide roller 505 fixed to the side wall of the rotating shaft 503 and the long rod 504 can rotate along the inner wall of the receiving hopper 403, and the conveyor belt 502 is wrapped around the side wall of the guide roller 505. The rotation of the guide roller 505 can drive the conveyor belt 502 to move, so that it can transport the screened material.

[0033] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the driving mechanism 2 includes a mounting frame 201 and a first motor 202. The mounting frame 201 is fixedly connected to the support seat 1, and the first motor 202 is fixedly installed on the mounting frame 201.

A second rotating wheel 205 is rotatably installed on the top of the sand making machine body 302, and a belt 204 is wound around the first rotating wheel 203 and the second rotating wheel 205.

[0034] Specifically, Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the crushing mechanism 6 includes a hammer plate 602 and a driving shaft 606. The second rotating wheel 205 is fixedly connected with the driving shaft 606. The driving shaft 606 is rotatably connected to the sand making machine body 302. The driving shaft 606 is sleeved with a plurality of sleeves 601 and hammer plates 602. The hammer plate 602 is rotatably connected with a hammer handle 604. A hammer head 605 is fixedly installed at the end of the hammer handle 604. A limit block 603 is threadedly connected to the driving shaft 606. One of the sleeves 601 contacts the sand making machine body 302. The limit block 603 is sleeved with the other sleeve. The top of the tube 601 is in contact with the waste slag and steel slag, and the waste slag and steel slag are discharged into the interior of the main mechanism 3. The control switch of the driving mechanism 2 is turned on, which can drive the crushing mechanism 6 to rotate in the main mechanism 3, thereby facilitating the crushing of the waste slag and steel slag, that is, the waste slag and steel slag to be processed can be transported to the upper hopper 301 through the material conveyor. Since the upper hopper 301 is connected to the interior of the sand making machine body 302, and the inner wall of the upper hopper 301 is arranged in an inclined structure, the material can be quickly discharged into the sand making machine body 302 through the upper hopper 301; when the waste slag and steel slag falls into the sand making machine body 302, The operator can turn on the control switch of the first motor 202, and the first motor 202 is fixed to the side wall of the mounting frame 201. The first motor 202 drives the first rotating wheel 203 to rotate. Since the first rotating wheel 203 is wound with a belt 204, the belt 204 can drive the second rotating wheel 205 to rotate when the first rotating wheel 203 rotates. The second rotating wheel 205 drives the driving shaft 606 to rotate inside the sand making machine body 302. The side wall of the driving shaft 606 is sleeved with a plurality of sleeves 601 and hammer plates 602. When the material falls vertically into the inside of the sand making machine body 302, the material and the hammer handle 606 are pressed against each other. 04, the hammer head 605 installed at the end can make the hammer head 605 hit the material through high-speed rotation, so that the material is broken into the required particle size, and the crushed material will be discharged from the lower hopper 305 installed at the bottom of the sand making machine body 302; when the internal components of the sand making machine body 302 need to be inspected, the operator can open the limit assembly of the inspection door 304, and then rotate the inspection door 304 to make it rotate along the fixed block 303 installed on the side wall of the sand making machine body 302, thereby putting the sand making machine body 302 in an open state, which is convenient for the operator to observe its internal situation.

[0035] When the present invention is in use, first, the waste slag and steel slag to be processed can be transported to the upper hopper 301 through the material conveyor. Since the upper hopper 301 is connected to the interior of the sand making machine body 302 and the inner wall of the upper hopper 301 is arranged in an inclined structure, the material can be quickly discharged into the sand making machine body 302 through the upper hopper 301; when the waste slag and steel slag falls into the sand making machine body 302, the operator can turn on the control switch of the first motor 202, the first motor 202 is fixed to the side wall of the mounting frame 201, and the first motor 202 drives the first rotating wheel 203 to rotate. Since the first rotating wheel 203 is wound with a belt 204, the belt 204 can drive the second rotating wheel 205 to rotate when the first rotating wheel 203 rotates, and the second rotating wheel 205 drives the drive shaft 606 in the sand making machine The inside of the body 302 rotates, and the side wall of the driving shaft 606 is sleeved with a plurality of sleeves 601 and hammering discs 602. When the material falls vertically into the inside of the sand making machine body 302, the material contacts the hammer head 605 installed at the end of the hammer handle 604, so that the hammer head 605 can hit the material through high-speed rotation, so that the material is broken into the required particle size, and the broken material will be discharged from the lower hopper 305 installed at the bottom end of the sand making machine body 302; when it is necessary to inspect the internal components of the sand making machine body 302, the operator can open the limit assembly of the inspection door 304, and then rotate the inspection door 304 to make it rotate along the fixed block 303 installed on the side wall of the sand making machine body 302, so that the sand making machine body 302 is in an open state, which is convenient for the operator to observe its internal conditions;

[0036] Since the lower hopper 305 is located at the center of the filter frame 406, when it discharges the crushed material into the filter frame 406, the control switch of the hydraulic rod 409 can be turned on. The hydraulic rod 409 is fixed inside the mounting plate 401. When the hydraulic rod 409 is started, the telescopic end thereof can drive the slide plate 410 to slide in the limiting groove 408 provided in the receiving hopper 403. The limiting groove 408 is also slidably installed with a slider 407. The slider 407 and the slide plate 410 are both fixedly connected to the side wall of the card frame 405. The hydraulic rod 409 drives the slide plate 410 to slide, so that the card frame 405 can be displaced along the inner wall of the receiving hopper 403, and then the slider 407 can slide in another limiting groove 408. The filter frame 406 is clamped and installed in the card frame 405. The material is screened by the filter frame 406 that slides back and forth, and the material with larger particles can be collected inside the filter frame 406, so as to facilitate improving the screening effect of the material.

[0037] The screened materials will fall to the top of the conveyor belt 502 through the mesh of the filter frame 406. Since the conveyor belt 502 is close to the bottom of the receiving hopper 403, when the control switch of the second motor 501 is started, it can drive the rotating shaft 503 to rotate inside the receiving hopper 403. A gear 506 is fixedly installed on the end of the rotating shaft 503 away from the second motor 501. The rotation of the gear 506 drives the chain 507 meshing with it to rotate, and then the chain 507 drives another gear 506 to rotate. The other gear 506 is fixedly connected to the long rod 504. When the rotating shaft 503 and the long rod 504 both rotate inside the receiving hopper 403, the guide roller 505 fixed to the side wall of the rotating shaft 503 and the long rod 504 can rotate along the inner wall of the receiving hopper 403. The conveyor belt 502 is wrapped around the side wall of the guide roller 505. The rotation of the guide roller 505 can drive the conveyor belt 502 to move, thereby causing it to transport the screened materials.
