Description

The drying sludge automatic control device

Technical field

The utility model relates to a kind of drying sludge automatic control equipment, especially drying sludge automatic control device.

Background technology

Produce municipal sewage plant every day a large amount of mud, the water ratio of mud greatly about about 80%, have only the moisture in the mud drop to 30%-16% following after, mud just can obtain further effectively utilization---burning electricity generation or composting.At present, adopt open-air airing and reduce water ratio in the mud for the method for mud heating evaporation usually.Adopt this method of open-air airing, the land area that takies is big, needs artificial cloth and stirring, the working strength of workers height; In addition, contain a large amount of bacteriums and virus in the mud, big to operator's Health hazard, also can have a negative impact to surrounding environment; When running into rainy day, mud flows away with rainwater and causes the pollution of water owing to can not in time collect.Therefore, open-air this traditional method of airing has very big drawback.Heating evaporation typically uses roller dryer, fluid bed dryer and paddle-dryer, the principle of work of these drying machines all is that the heat by generations such as burning coal, Sweet natural gas, biogas heats mud and makes moisture evaporation in the mud, reaches the purpose that reduces water ratio.Adopt these methods can consume a large amount of energy, the mud of dry one ton of water ratio 80% need consume more than 100 kilogram of standard coal, in addition, after hot blast that roasting kiln produces and mud mix, the water vapour that produces need be discharged with induced draft fan, contain tiny solid particle and irritating gas in the water vapour of discharging, cause atmospheric pollution, influence surrounding enviroment.More than these several desiccating methods, big, the polluted air of power consumption is unfavorable for energy-conserving and environment-protective.

Summary of the invention

In order to overcome the deficiency of existing equipment, the utility model provides a kind of novel drying sludge automatic control device.This drying sludge automatic control device has characteristics such as energy-conservation, pollution-free, level of automation height.

The technical scheme that its technical problem that solves the utility model adopts is: the drying sludge automatic control device, at first build a Steel Bracket booth, one side of booth, the rear portion, the top is sealed with light transmissive material, the opposite side cement wall, the mud greenhouse and the heat collecting chamber that separate a rear portion UNICOM between two abutment walls, there are two reducing motors of symmetry outside, mud greenhouse, advance sprocket wheel and motion-work wheel respectively are housed on the reducing motor, the inside has follow-up pulley successively and retreats sprocket wheel, chain, cylinder and retreat cylinder advances, wireline, there are two pulleys the inside in mud greenhouse, article two, two walking beams are arranged before and after having between the wireline, the lower end of walking beam is two pair rollers respectively, there is guide rail the roller below, on two web plates contiguous block is arranged between the walking beam, on the walking beam of the inside equally distributed perpendicular scraper plate is arranged, mud is arranged below it, the equally distributed oblique scraper plate that can lift is arranged between the walking beam, an end has the hopper of band discharge port between two guide rails, there is motor its front, there is worm conveyor the hopper bottom surface, in the other end melt pit storage hopper is arranged between two guide rails, there are former and later two travel switches the outer end of a side wireline, and the outer basifacial of heat collecting chamber has blower fan and fan supporter.

The drying sludge automatic control device is that the heat that utilizes solar radiation to produce carries out heat drying to mud.Light transmissive material adopts high glass or the plastics film of transmittance.

This drying sludge automatic control device working process: mud is packed in the hopper, start the cloth motor and start reducing motor simultaneously and just change, walking beam advances, and places the worm conveyor rotation on the walking beam that mud is discharged to ground by discharge port.Place the oblique scraper plate on the walking beam successively mud to be turned to the right.When walking beam was run into travel switch near terminal point, cloth motor and reducing motor cut off the power supply automatically, and walking beam halts, and the drying sludge automatic control device quits work.Start the reducing motor counter-rotating, walking beam retreats, and tiltedly scraper plate lifts automatically, and perpendicular scraper plate is wipeed mud off.When arrival zero position walking beam was run into travel switch, reducing motor cut off the power supply automatically, and walking beam stops.Finished a working cycle this moment.

The beneficial effects of the utility model are, this drying sludge automatic control device improves more than three times in drying sludge efficient on the same working area, and the rainy day can not have a negative impact to the drying of mud yet, has reduced working strength of workers simultaneously.The relative traditional drying method of this technical scheme has characteristics such as energy-conservation, pollution-free, that level of automation is high, efficient is high, working cost is low.
