[0001] The utility model relates to the technical field of slag crushing equipment, and particularly discloses a waste slag crushing device. Background Art

[0002] Waste slag refers to the slag produced in the industrial production process, mainly from the metallurgical, coking and electric power industries. The main components of waste slag are oxides, including iron oxide, calcium oxide and magnesium oxide, and also contain a small amount of metal and non-metallic elements. Waste slag can be used in the construction industry, agricultural industry, environmental protection industry and road construction. During the production and use process, a crushing device is required to crush large particles of waste slag into small particles for subsequent processing and use.

[0034] like Figure 3 and Figure 5As shown, the two first filter plates 271 and the second filter plates 272 respectively pass through the interior of the two side plates 214 and are slidably connected to the side plates 214. The two ends of the first filter plates 271 and the second filter plates 272 are respectively slidably connected to the two first slide grooves 2131. The telescopic ends of the first telescopic rod 273 and the second telescopic rod 275 are respectively detachably connected to the first filter plates 271 and the second filter plates 272, so that the first telescopic rod 273 and the second telescopic rod 275 can respectively drive the first filter plates 271 and the second filter plates 272 to move inside the side plates 214. Before the two filter plates are inspected and cleaned, the two filter plates are moved from the side plates 214 close to the first installation plate. Pull one side of the plate 211 to the other side, and reset the two filter plates after the inspection and cleaning are completed. The first telescopic rod 273 and the second telescopic rod 275 are both connected to the bracket 1, which is convenient for the installation and maintenance of the above-mentioned telescopic rods. The first telescopic rod 273 and the second telescopic rod 275 are respectively provided with a first guide rod 274 and a second guide rod 276 on both sides. The first guide rod 274 and the second guide rod 276 both pass through the interior of the bracket 1 and are slidably connected to the bracket 1, which can limit the moving direction of the two filter plates, provide support for the two filter plates during the process of adjusting the position of the two filter plates, and extend the service life of the first telescopic rod 273 and the second telescopic rod 275.

[0035] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, second chutes 2181 are provided on both sides of the inner wall of the discharge pipe 218, and the two ends of the blocking plate 28 are slidingly connected to the two second chutes 2181 respectively. The blocking plate 28 passes through the interior of the discharge pipe 218 and is slidingly connected to the discharge pipe 218. One side of the blocking plate 28 is connected to a third telescopic rod 29, and the outer side of the third telescopic rod 29 is connected to the bracket 1. The above design can extend the blocking plate 28 into the discharge pipe 218 to block the discharge pipe 218 during the process of cleaning the first filter plate 271 and the second filter plate 272 one by one or when the waste slag only needs to be crushed without filtering. After cleaning or crushing, the blocking plate 28 is pulled out from the discharge pipe 218 to ensure that the crushed waste slag is smoothly discharged from the inside of the shell 21.

[0036] like Figure 1 and Figure 2 As shown, a controller 3 is provided on one side of the bracket 1 to facilitate the control of the operation of relevant components in the crushing device.

[0037] The waste slag crushing device disclosed in this embodiment determines whether filtering and screening are required according to the crushing requirements of the waste slag to be crushed before use. When filtering and screening is required, the controller 3 is used to start the third telescopic rod 29, so that the third telescopic rod 29 is contracted to completely pull the blocking plate 28 out of the discharge pipe 218 and then close it, and the original material receiving device is connected to the discharge pipe 218 or placed under the discharge pipe 218. The controller 3 is used to start the motor 22, so that the motor 22 drives the first crushing blade 24 and the second crushing blade 25 to rotate through the transmission shaft 23, and the large volume of waste slag to be crushed is injected from the feed hopper 216 into the cavity formed by the top plate 215 and the two first filter plates 271, and is crushed into smaller volumes by the first crushing blade 24. After the particles are collected, the waste slag smaller than the filter holes in the first filter plate 271 passes through the filter holes and falls downward into the cavity formed by the first filter plate 271 and the second filter plate 272, and is further crushed by the second crushing blade 25. The waste slag smaller than the filter holes in the second filter plate 272 passes through the filter holes and falls downward into the discharge bin 217 and is discharged to the receiving device through the discharge pipe 218. The waste slag particles with a slightly larger volume above the first filter plate 271 and the second filter plate 272 are further crushed by the first crushing blade 24 and the second crushing blade 25 and then fall into the discharge bin 217. The waste slag particles that cannot be crushed remain on the first filter plate 271 and the second filter plate 272. After a period of time, the particles on the first filter plate 271 and the second filter plate 272 are observed through the transparent plate 212. In the case of residual waste slag, when the amount of residual slag accumulates to a sufficient amount, turn off the motor 22, remove the transparent observation plate, clean the residual waste slag that cannot be crushed on the first filter plate 271 and the second filter plate 272, and after the filter holes are unblocked, reinstall the transparent observation plate, use the controller 3 to start the motor 22 again, and then continue the waste slag crushing operation. The filter holes can also be unblocked without removing the transparent plate 212. After turning off the motor 22, use the controller 3 to control the two first telescopic rods 273 and the second telescopic rod 275 to retract in turn, so as to drive the two first filter plates 271 and the second filter plates 272 to slide in the first slide groove 2131, so that the first guide rod 274 and the second guide rod 276 slide inside the bracket 1 To limit the moving direction of the first filter plate 271 and the second filter plate 272, the first insertion rod 2712 and the second insertion rod 2722 are separated from the first slot 2711 and the second slot 2721 respectively, and the two first filter plates 271 and the second filter plates 272 are pulled in turn from the side of the two side plates 214 close to the transmission shaft 23 to the side away from the transmission shaft 23 to dredge the filter holes. After the dredging is completed, the two first telescopic rods 273 and the second telescopic rods 275 are controlled to extend in turn to reset the two first filter plates 271 and the second filter plates 272, restore the connection between the first insertion rod 2712 and the first slot 2711, and restore the connection between the second insertion rod 2722 and the second slot 2721, and then start the motor 22 to continue the waste slag crushing operation.

[0038] When the crushing demand of the waste slag does not require filtering and screening, before crushing, the original material receiving device is connected to the discharge pipe 218 or placed under the discharge pipe 218, and the controller 3 is used to control the third telescopic rod 29 to extend to push the blocking plate 28 back into the discharge pipe 218 to block the discharge pipe 218, and the controller 3 is used to control the first telescopic rod 273 and the second telescopic rod 275 to contract in turn, and the two first filter plates 271 and the second filter plates 272 are pulled from the side of the two side plates 214 close to the transmission shaft 23 to the side away from the transmission shaft 23 in turn, so that the first filter plate 271 and the second filter plate 272 are away from the end of the first telescopic rod 273 and the second telescopic rod 275 respectively block the through holes of the side plates 214 penetrated by the above two filter plates, and a sufficient amount of The waste slag to be crushed is thrown into the cavity formed between the top plate 215 and the blocking plate 28 through the feed hopper 216, and the controller 3 is used to start the motor 22, so that the motor 22 drives the first crushing blade 24 and the second crushing blade 25 to rotate through the transmission shaft 23 to crush the waste slag. After the crushing is completed, the controller 3 is used to control the third telescopic rod 29 to retract, and the blocking plate 28 is pulled out from the discharge pipe 218, so that the crushed waste slag is discharged to the receiving device through the discharge pipe 218. After the waste slag inside the outer shell 21 is discharged, the third telescopic rod 29 is controlled to extend, and the blocking plate 28 is pushed back into the discharge pipe 218, and a sufficient amount of waste slag to be crushed is injected into the inner part of the outer shell 21 again, and the crushing operation of the next batch of waste slag can be carried out.
