Detailed description of the invention
Below in conjunction with drawings and Examples, technical scheme of the present invention is described in further detail.
A kind of multi-channel semi-dry sludge shifter as shown in Figure 1, comprise the main channel 1 of sewage sludge feed, first passage 2, second channel 3, deflecting plate 4, deflecting plate clamping plate 14, dash plate 5, turnover panel 6, axis of revolution 7, connecting rod 8, actuating cylinder 9, inspection socket A10, inspection socket B11, stent support 12, and butt flange (13,15,16); Wherein:
Axis of revolution 7 is fixedly connected on the point of interface place of first passage 2 and second channel 3, is connected with actuating cylinder 9 outside first passage 2, and the type selecting of actuating cylinder 9 is determined by the size calculating stroke thrust and pulling force.Actuating cylinder 9 is connected with axis of revolution 7 by connecting rod 8, axis of revolution 7 is fixed with turnover panel 6 (comprising the first turnover panel of first passage 2 and the second turnover panel of second channel 3), the switching that actuating cylinder 9 drives turnover panel 6 to realize between first passage 2 and second channel 3 by arranging flexible stroke.The inlet point of main channel 1 is connected by main channel butt flange 13 with the mud mouth of drier 17, first passage 2 is connected with conveyor screw B22 with conveyor screw A21 with second channel butt flange 15 respectively by first passage butt flange 16 with the discharging opening of second channel 3, the good seal performance of Flange joint and not high to the accuracy requirement of shell, not only save tooling cost, also achieve Assembly &Disassembly effect easily.Mud is finally transported to back incinerator 31 and processes, and wherein during a passage maintenance, is switched to another passage.
In Practical Project, moisture percentage in sewage sludge after drying machine 17 processes is about 80%, the water ratio of mud is 40-60%, mud temperature about 90 DEG C, according to mud humiture and viscosity characteristics, in main channel 1, inlet point place is provided with deflecting plate 4, and deflecting plate 4 and main channel 1 inwall angle are about 13 ° (between 10-15 °), such design can either make sewage sludge feed unobstructed, not easily blocking channel.Dewatered sludge due to water ratio 40-60% is solid-state, and poor fluidity is easily built bridge, and the bore of main channel 1 can be selected comparatively large, as selected main channel 1 internal diameter size to be 410mm × 610mm.
Consider that manufacture and the facility location of device are convenient, by main channel 1 and second channel 3 at right angle setting, consider the steady charging of mud and unobstructed, first passage 2 and second channel 3 angle are set to 30 ° (between 25-35 °), and first passage 2 and second channel 3 internal diameter size are designed to 410mm × 410mm.
First passage 2 outer wall is connected with actuating cylinder 9, and the line of centers of actuating cylinder 9 overlaps with the line of centers of first passage 2, and such design can make cylinder be convenient to switch, and makes structure optimization simultaneously.In addition first passage 2 and second channel 3 arrange inspection socket A10 and inspection socket B11, as a kind of preferred embodiment, its internal diameter is all designed to 200mm × 200mm.
When considering switching; turnover panel 6 can be got to rapidly the inwall of another passage under the drive of actuating cylinder 9 by a passage; in order to fender guard; dash plate 5 is provided with at first passage 2 and the second logical 3 road inwalls; thickness 6mm; cross section is 100mm × 400mm, when the plate that turnover panel 6 gets to respective channel playing shock resistance effect, the service life of extension fixture.
In system operation, because moisture percentage in sewage sludge is at 40-60%, viscosity is easy to greatly glutinous wall, long working can cause channel blockage, therefore the both sides outer rim of turnover panel 6 is processed into serration, under the sludge scraping that vias inner walls can be sticked together during switching, the self-cleaning function of implement device, avoids the blocking of passage to greatest extent.
The effect of multi-channel semi-dry sludge shifter realizes interchannel to switch, and namely when after the device fails such as the conveyor screw in a circuit or gig, can switch on extension wire by sludge conveying system, the concrete conveyor line of this sludge conveying system is:
1, first by water ratio be 80% wet mud drying machine 17 drying and other treatment, make moisture percentage in sewage sludge at 40%-60%, mud temperature about 90 DEG C, mud after mummification is delivered to dewatered sludge distributing box 19, if now reprint 6 is positioned at first passage 2 place, due to inertia and Action of Gravity Field, switch to second channel 3 from multi-channel semi-dry sludge;
2, the first passage of multi-channel semi-dry sludge shifter 19 will deliver to conveyor screw A21, and conveyor screw A21 has cooling effect, and the mud temperature after mummification is down to less than 50 DEG C, prevent high temperature mud moisture absorption and hardening in dewatered sludge storage warehouse;
3, mud delivers to dewatered sludge chain plate lifting machine A23 through conveyor screw A21, and dewatered sludge chain plate lifting machine A23 will send into dewatered sludge storage warehouse A25 after sludge lifting to certain altitude.
4, dewatered sludge storage warehouse A25 arranges level-sensing device, multi-point temp detection instrument, CH4 checking system, oxygen content monitoring system and odor collection system etc., requires mud to deliver to dewatered sludge hopper A27 according to setting.
5, mud is finally transported to incinerator 31 burning disposal through dewatered sludge hopper A27, conveyor screw C29.
6, the conveying flow process of another passage of mud and said process similar, second channel will deliver to dewatered sludge spiral B22, mud is delivered to dewatered sludge chain plate lifting machine B24 by dewatered sludge spiral B22, and dewatered sludge chain plate lifting machine B24 will send into dewatered sludge storage warehouse B26 after sludge lifting to certain altitude.Dewatered sludge storage warehouse B26 requires mud to be transported to incinerator 31 burning disposal through dewatered sludge hopper B28 and conveyor screw D30 according to setting.
As mentioned above, embodiments of the invention are explained, obviously, as long as do not depart from fact inventive point of the present invention and effect, will be readily apparent to persons skilled in the art distortion, is also all included within protection scope of the present invention.
