In the utility model, the pretreatment unit of oily sludge is to the pretreatment process of solid-state oily sludge and device before thermal desorption oil-sludge treatment.By oily sludge is carried out of short duration storage, limitation export, in course of conveying to oily sludge through vibratory screening apparatus, remove the oversize material that particle diameter is greater than specified size, remove the ferromagnetic class impurity in material by magnetic force screening plant again, thus make material reach the feed needs of thermal desorption cavity.
Accompanying drawing explanation
Fig. 1 is the composition schematic diagram of mud pretreatment unit in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is elaborated.
As shown in Figure 1, the pretreatment unit of the utility model oily sludge includes feed storage hopper 1, material metering weighing belt 2, material shaking-sieving device 3, material magnetic force separating screen device 4, device for transporting objects 5, electrical autocontrol system 6.The automatic operation of automatic control system 6 unified cooperation control feed storage hopper 1, material metering weighing belt 2, material shaking-sieving device 3, material magnetic force separating screen device 4, device for transporting objects 5.
Wherein: material metering weighing belt 2 is placed in below the outlet of feed storage hopper 1, the discharging direction of feed storage hopper 1 is provided with cloth adjustable plate, and the mode that material can tile is layered on material metering weighing belt 2.
Shaking-sieving device 3 is positioned at below material metering weighing belt 2, and is positioned at the tail end of material metering weighing belt 2, for receiving the oily sludge that material measuring belt scale conveying 2 is carried at regular time and quantity; Device for transporting objects 5 is placed in the exit of shaking-sieving device 3.Be connected with the outlet of shaking-sieving device 3.Shaking-sieving device 3 is provided with the screen cloth of 40mm, is driven by vibration motor, and is provided with screen overflow relief outlet and screen underflow discharge port, and screen underflow discharge port is positioned at directly over device for transporting objects 5 feed end.The output terminal of device for transporting objects 5, higher than input terminus, makes oily sludge up carry, and namely device for transporting objects 5 is 10-15 degree with the angle of inclination of level.The upper surface of the belt conveyor of device for transporting objects 5 is provided with the material magnetic force separating screen device 4 for removing Ferromagnetic Impurities in oily sludge, this material magnetic force separating screen device 4 has multiple, be arranged on the top of the belt conveyor of device for transporting objects 5 abreast, and and distance between belt conveyor between 5-10cm.
Material metering weighing belt 2 includes belt and claims and belt conveyor, drives interlocking, the load of complete assembly is stablized controlled by variable-frequency motor.
Detailed process is as follows: supplied materials oily sludge enters feed storage hopper 1 by carrying, supplied materials is carried out to storage and the buffering of short period of time, makes the streams in system continuous.Oily sludge in feed storage hopper 1 successively outputs in material shaking-sieving device 3 according to setting flow by material metering weighing belt 2.Remove the flexible impurity of stone oversize in material, impurity and fiber-like by material shaking-sieving device 3, the oily sludge after process enters device for transporting objects 5, carries backward; Oily sludge is in the conveying of device for transporting objects 5, due to conveying of tilting, speed is more slow, removed the Ferromagnetic Impurities in material by material magnetic force separating screen device 4 after material magnetic force separating screen device 4, namely the Ferromagnetic Impurities the most easily causing in oily sludge and get stuck is eliminated, such as iron rod and iron wire etc.
Continuously to be transported to follow-up heat by device for transporting objects 5 through the oily sludge of the shaking-sieving of material shaking-sieving device 3 and the screening of magnetic force material magnetic force separating screen device 4 to be separated in treatment unit (thermal desorption heating cavity) and to process.Because oily sludge is through being separated screening, the impurity not meeting hot phase-separation system charging is removed, thus ensures the steady running of hot phase-separation system.
Electrical autocontrol system 6 in the utility model for realizing the automatic operation of material metering weighing belt 2, material shaking-sieving device 3, device for transporting objects 5, and controls the load of adjustment material metering weighing belt 2, the trouble lamp function of device inside.Electrical autocontrol system 6 also can be connected with the central control system of whole project as required, realize remote monitoring and automatically run, due to electrical autocontrol system 6 for a person skilled in the art, can simple realization under specific requirement, therefore no longer describe in detail.
In sum, the pretreatment unit in the utility model, by being combined with mechanical grading and magnetic force sieves two kinds of method for sieving, can remove plurality of impurities simultaneously, avoids the phenomenon getting stuck and shut down to greatest extent.Mud, by the way of magnetic force sub-sieve, eliminates the Ferromagnetic Impurities the most easily causing in oily sludge and get stuck, such as iron rod and iron wire etc.Thus the feed needs of thermal desorption process can be met, ensure that the normal table of oily sludge thermal desorption oil-sludge treatment runs, material size screening and the process of ferromagnetic class Impurity removal are carried out to solid-state oily sludge.
