FIG. 1 is a schematic diagram of the system of the present invention.
Detailed Description
The technical scheme of the invention is further explained by combining the drawings and the embodiment.
Referring to fig. 1, the invention firstly discloses a conveyor material cleaning and recycling system, which can not only clean a conveyor, but also recycle the residues removed by cleaning, thereby saving material resources and optimizing the system structure.
As shown in fig. 1, the conveyor material cleaning and recycling system of the present invention mainly includes a conveyor, a cleaning box 101, a stirring tank 502, a chemical feeding device, a solid-liquid separation device 403, a clean water tank 501, and a solid treatment device. During the operation of the conveyor, a high-pressure nozzle is arranged near the conveyor, cleaning liquid is sprayed out of the high-pressure nozzle to clean the conveyor, and material residues adhered to the conveyor are swept from the surface of the conveyor by using the impact and the moistening action of the cleaning liquid.
A cleaning box 101 is provided below the conveyor, particularly below the end of the conveyor. The purge bin 101 may generally be a box for receiving the mixed material falling from the conveyor. The mixed material collected in the purge bin 101 is typically a residue of material having a certain water content, i.e. a slurry. The purge tank 101 is connected to the agitation tank 502 by a pipe so as to transfer the slurry into the agitation tank 502.
In the present invention, the conveyor may be any form of industrial and commercial article transport means, particularly a belt conveyor used in steel smelting and production systems. Furthermore, the cleaning liquid may be any form of usable liquid, in particular fresh water or fresh water with little impurities.
In a preferred embodiment of the present invention, a slurry pressurizing pump 102 is provided in a pipe connecting the cleaning tank 101 and the agitation tank 502, and pressurizes slurry conveyed through the pipe. In the whole conveyor material cleaning and recovering system of the invention, the physical distances between the devices are likely to be far apart according to the requirements of the actual production process or the production environment, so that the mud pressure pump 102 arranged between the sweeping box 101 and the stirring tank 502 can be better suitable for the remote mud conveying.
A stirrer 401 and a feed pump 402 are provided in the stirring tank 502, the stirrer 401 stirs a mixture (slurry) to ensure that the slurry in the stirring tank 502 does not settle, and the feed pump 402 pressurizes the slurry in the stirring tank 502 to feed the slurry to the solid-liquid separation device 403. Preferably, the agitation tank 502 receives the mixture (slurry) transferred from the cleaning tank 101, and therefore the agitation tank 502 may be preferably a slurry agitation tank in terms of model selection, and the agitator 401 in the agitation tank 502 may be preferably a slurry agitator. It will be appreciated by those skilled in the art that other types of stirred tanks, blenders, are still suitable for use with the present invention.
As can be seen from fig. 1, the agitation tank 502 is connected to the solid-liquid separation device 403 through a pipeline, and the slurry in the pipeline is pressurized due to the pressurization of the slurry by the feed pump 402. A pipeline mixer 414 is also arranged on the pipeline between the stirring tank 502 and the solid-liquid separation device 403, and the pipeline mixer 414 is connected to the dosing device. The chemical feeding device adds the treatment chemical to the pipeline between the agitation tank 502 and the solid-liquid separation device 403 through the pipeline mixer 414, so that the treatment chemical and the pressurized mixture (slurry) are sufficiently mixed, thereby improving the flocculation property and the sedimentation property of the slurry. In the present invention, the pressurization of the slurry by the charge pump 402 not only facilitates the delivery of the slurry, but also, in conjunction with the line mixer 414, allows the treatment agent and the slurry to be mixed thoroughly.
As a preferred embodiment of the present invention, there are three drug adding devices, namely, a polyaluminum chloride (PAM) drug adding device 410, a Polyalenamine (PAC) drug adding device 411 and a NaOH drug adding device 412. Correspondingly, three pipeline mixers 414 are arranged on the pipeline between the stirring tank 502 and the solid-liquid separation device 403, and respectively correspond to the PAM dosing device 410, the PAC dosing device 411 and the NaOH dosing device 412, so that the corresponding treatment agents stored in the dosing devices, namely, the polyaluminum chloride solution, the polyalenamine solution and the NaOH solution, are mixed with the slurry in the pipeline.
Continuing to refer to fig. 1, the solid-liquid separation apparatus 403 receives the pressurized mixture to which the treatment chemical is added from the pipeline, and performs solid-liquid separation on the pressurized mixture to which the treatment chemical is added. In a preferred embodiment of the present invention, the solid-liquid separator 403 performs solid-liquid separation of the slurry to which the treatment chemical is added, and therefore the solid-liquid separator 403 is preferably an efficient sludge-water separator, such as an inclined plate sedimentation tank. It will be appreciated by those skilled in the art that other types of solid-liquid separation devices are equally suitable for use in the system of the present invention.
The solid-liquid separator 403 (inclined plate sedimentation tank) is used for increasing the removal rate of solid particles by increasing the number of shallow layers by using the shallow tank sedimentation principle. After the slurry is precipitated, the solid-liquid separator 403 transfers the liquid separated material (i.e., supernatant liquid, which is precipitated sewage) to the clean water tank 501, and transfers the solid separated material (precipitated slurry) to the solid treatment device.
The clear water tank 501 is connected to a sweep water pressurizing pump 10, and the sweep water pressurizing pump 10 pressurizes the liquid stored in the clear water tank 501, so that the pressurized liquid (sweep water) can be used for conveyor cleaning. Preferably, the cleaning water is sprayed onto the return adhesive tape through a spray head arranged below the return adhesive tape of the adhesive tape machine.
As can be seen from FIG. 1, an additional line mixer 415 is further provided on the line between the solid-liquid separation apparatus 403 and the solid treatment apparatus, and the line mixer 415 is connected to a PAC chemical feeding apparatus 411, so that the solid separated material transferred from the solid-liquid separation apparatus 403 to the solid treatment apparatus is mixed with the polyenoic acid amine solution.
In a preferred embodiment of the present invention, the solid-liquid separator 403 is further connected to a sludge transfer pump 404. Similar to the feed pump 402 in the stirred tank 502, the sludge transfer pump 404 pressurizes the settled slurry, which not only helps to transfer the settled slurry, but also helps to cooperate with the line mixer 415 to allow the polyenoic amine solution and the settled slurry to mix thoroughly.
With continued reference to FIG. 1, the solids processing apparatus includes a sludge flocculation tank 405, a flocculation tank blender 406, a sludge dewatering machine 407, a filtrate slurry recirculation pump 409, and a screw conveyor 408. As shown in fig. 1, a flocculation tank stirrer 406 is provided in the sludge flocculation tank 405, the sludge flocculation tank 405 receives the solid-liquid separation of the solid-liquid separation device 403, and the flocculation tank stirrer 406 stirs the solid-liquid separation, thereby sufficiently mixing the polyenoic acid amine solution with the slurry by the stirring action and enhancing the coagulation of solid particles in the slurry. The outlet of the sludge flocculation tank 405 is connected to a sludge dewatering machine 407, and the sludge dewatering machine 407 dewaters the water-containing solid separated material to cake-like solid with a water content less than the requirement, i.e., mud cake. The sludge dewatering machine 407 is connected to the filtrate slurry reflux pump 409 and the screw conveyor 408 respectively, and liquid separated from the solid separation material in the dewatering process is conveyed back to the solid-liquid separation device 403 through the filtrate slurry reflux pump 409, and sludge cake left in the dewatering process is conveyed to the screw conveyor 408. The solid-liquid separation device 403 performs precipitation filtration on the returned liquid, and the screw conveyor 408 further conveys the treated mud cake back to the conveyor, so that the mud cake can be recycled.
In a preferred embodiment of the present invention, sludge dewatering equipment 407 is disposed below flocculation agitation tank 502, and sludge dewatering equipment 407 is preferably a spinning type sludge dewatering equipment 407.
In the material cleaning and recycling system of the conveyor of the present invention, the number of conveyors may be one or more, and all of them are applicable to the system of the present invention. The system shown in fig. 1 includes 3 conveyors 1#, 2#, 3#, so that a cleaning tank 101, 201, 301 and a slurry pressurizing pump 201, 202, 203 are provided below each conveyor, and each cleaning tank 101, 102, 103 receives the mixed materials falling from the corresponding conveyor and conveys the mixed materials to a stirring tank 502 by the slurry pressurizing pump 201, 202, 203. In the present embodiment, the agitation tank 502 receives the mixture materials conveyed from the plurality of cleaning tanks 101, 102, 103 and collectively agitates the mixture materials. The subsequent system structure is the same as that of a single conveyor, and therefore, the description is omitted.
Besides the system structure, the invention also discloses a corresponding method for cleaning and recovering the materials of the conveyor, which mainly comprises the following steps:
s1: the conveyor is cleaned and the mixed material falling from the conveyor is received.
