[0002] In the process of chemical production, a large amount of slag is often generated. Some slag may contain various metals or inorganic salt substances. If not treated, during the landfill or utilization of the slag, the beneficial parts will be wasted, and the harmful components will leach out and pollute the environment. Therefore, a pretreatment system is needed to pretreat it.

[0003] The pretreatment system often directly processes all slag, and it is not easy to screen the slag before treatment, which easily causes waste of recyclable metals and other materials contained in the slag; generally, the slag needs to be cleaned and decontaminated before pretreatment. When cleaning, the solution will become turbid due to the mixed cleaning dust, which easily affects the cleaning and decontamination effect when the pretreatment system is used; the pretreatment system generally preprocesses the slag by crushing, and the crushed slag is discharged through a screen.

A recovery component 302 is provided on the surface of the recovery box 301. The inside of the recovery component 302 includes a material guiding frame 3021, a box cover 3022 and an electromagnetic iron plate 3023. The material guiding frame 3021 is fixed on the outside of the recovery box 301. The material guiding frame 3021 is communicated with the crushing box 102. The surface of the recovery box 301 is covered with the box cover 3022. The box cover 3022 is detachably connected to the recovery box 301 by screws. An electromagnetic iron plate 3023 is installed on the surface of the box cover 3022. The model of the electromagnetic iron plate 3023 can be selected from the MW series.

[0029] During use, the electromagnetic iron plate 3023 is controlled to work through the control row key 101. During use, the slag after cleaning is discharged into the inside of the recovery box 301 along the discharge pipe 2024. Since the inner wall at the bottom position of the recovery box 301 is of an inclined structure, it is convenient for the slag to slide down under the action of gravity. At this time, under the magnetic attraction of the electromagnetic iron plate 3023, the metal in the slag can be attracted to the surface of the electromagnetic iron plate 3023 to recover the metal. The remaining slag is discharged into the inside of the crushing box 102 through the material guiding frame 3021.

Under the action of the driving motor 4013, the rotating rod 4012 is driven to rotate, and the cam 4011 is driven to rotate. One end of the cam 4011 away from the rotating rod 4012 jacks up the screen 2012, causing the screen 2012 to slide along the chute 403. When the cam 4011 rotates away from the screen 2012, the screen 2012 falls and resets under the action of gravity and the assistance of the extension spring 402, so that the vibrating material mechanism 4 drives the screen 2012 to move up and down reciprocally, vibrate the screen 2012, and accelerate the feeding speed of the slag, so as to realize the vibrating material function of the pretreatment system.

[0032] Further, as Figure 2 shown, a circulating cleaning mechanism 5 is arranged on one side of the bottom plate 1.

One end of the retaining seat 502 is fixedly connected to one end of the filter screen 2023. A screen mesh 503 is fixed on the bottom inside the cleaning tank 104. The structure of the screen mesh 503 is an inclined structure. One end of the screen mesh 503 is fixedly connected to the bottom of the retaining seat 502. A circulating component 501 is arranged on one side of the cleaning tank 104. The inside of the circulating component 501 includes a water pump 5011 and a return pipe 5012. A water pump 5011 is installed on one side of the bottom plate 1. The model of the water pump 5011 can be selected from the SLG series. The input end of the water pump 5011 is electrically connected to the output end of the control row key 101. One end of the water pump 5011 extends to the inside of the cleaning tank 104 at the top position through a pipeline. The other end of the water pump 5011 is fixed with a return pipe 5012. One end of the return pipe 5012 extends to the inside of the bottom plate 1. The return pipe 5012 is located on one side of the screen mesh 503.

[0033] During use, the sewage during cleaning falls to the bottom of the cleaning tank 104 through the filter screen 2023. At the same time, the water pump 5011 can be controlled to work through the control row key 101, so that the water pump 5011 sucks the sewage filtered by the screen mesh 503 into the return pipe 5012 and returns it to the inside of the cleaning tank 104 through the water pump 5011, reducing the turbidity of the cleaning slag solution, so as to realize the circulating cleaning function of the pretreatment system for the slag.

[0034] Working principle: When in use, first pour the slag to be pre-treated into the interior of the cleaning tank 104, and inject cleaning water into the interior of the cleaning tank 104. Subsequently, operate the control discharge key 101 to make the control discharge key 101 control the operation of the stirring motor 2022. Under the action of the stirring motor 2022, drive the stirring blade 2021 to rotate, stir and clean the slag. After the cleaning is completed, discharge the sewage through the bottom of the cleaning tank 104. Subsequently, operate the control discharge key 101 to make the control discharge key 101 control the opening of the control valve 2025, so that the slag is discharged along the discharge pipe 2024, so as to realize the cleaning and impurity removal function of the pre-treatment system for the slag.

[0035] During cleaning, the sewage falls to the bottom of the cleaning tank 104 through the filter screen 2023. At the same time, the operation of the water pump 5011 can be controlled through the control discharge key 101, so that the water pump 5011 sucks the sewage into the interior of the return pipe 5012 after filtering through the wire mesh 503 and returns it to the interior of the cleaning tank 104 through the water pump 5011, reducing the turbidity of the solution for cleaning the slag, so as to realize the circulating cleaning function of the pre-treatment system for the slag, thereby improving the cleaning and impurity removal effect of the pre-treatment system for the slag.

[0036] Subsequently, control the operation of the electromagnetic iron plate 3023 through the control discharge key 101. When in use, the cleaned slag is discharged along the discharge pipe 2024 into the interior of the recycling box 301. Since the inner wall at the bottom position of the recycling box 301 is of an inclined structure, it is convenient for the slag to slide down under the action of gravity. At this time, under the magnetic attraction of the electromagnetic iron plate 3023, the metal in the slag can be adsorbed onto the surface of the electromagnetic iron plate 3023 to recycle the metal. The remaining slag is discharged into the crushing box 102 through the guide frame 3021. After the pre-treatment system is used up, the box cover 3022 can be removed by loosening the screws, and then the metal on the surface of the electromagnetic iron plate 3023 can be removed, so as to realize the recycling function of the pre-treatment system for the metal in the slag, thus avoiding the waste of metal resources in the slag during the use of the pre-treatment system.

[0037] After the cleaned slag enters the interior of the crushing box 102, the control discharge key 101 controls the operation of the crushing motor 2011. Under the action of the crushing motor 2011, drive the two crushing rollers 2013 to rotate relatively to crush the slag. The crushed slag is discharged through the screen 2012, so as to realize the crushing function of the pre-treatment system for the slag.

[0038] Meanwhile, the control row keys 101 can be operatively controlled to control the driving motor 4013 to work. Under the action of the driving motor 4013, the rotating rod 4012 is driven to rotate, and the cam 4011 is driven to rotate, so that one end of the cam 4011 away from the rotating rod 4012 jacks up the screen 2012, and the screen 2012 slides along the sliding groove 403. When the cam 4011 rotates away from the screen 2012, the screen 2012 falls and resets under the action of gravity and the assistance of the extension spring 402. Thus, the vibrating material mechanism 4 drives the screen 2012 to reciprocate up and down to vibrate the screen 2012, accelerating the feeding speed of the slag, so as to realize the vibrating material function of the pretreatment system, thereby improving the working efficiency during the use of the pretreatment system, and finally completing the use work of the pretreatment system.
