Abstract
The utility model relates to drying equipment and in particular relates to a single-channel rotary sludge drier. The single-channel rotary sludge drier comprises a belt filter press, a belt conveyer, a feeding end holder, a rotary drum, a filter, a draught fan, a combustor, a discharging end holder, carrier rollers, a speed reducer, a motor, limiting rollers, a scraping stirrer and a scraping blade, wherein the belt conveyer passes through the feeding end holder and is connected with the discharging end holder through the rotary drum, the draught fan is connected with the rotary drum through the filter, the motor is connected with the carrier rollers and the rotary drum in sequence through the speed reducer, the scraping stirrer and the scraping blade are positioned in the rotary drum, and the limiting rollers are arranged on the side surface of the rotary drum. Sludge has the characteristics of certain viscosity, small granularity and the like and is easy to aggregate and agglomerate in a drying process. The sludge is easy to adhere to a drum body and accumulate and block to influence normal operation of the drier and reduce drying efficiency in a process of entering the drier.
Description
Technical field:
The utility model designs a kind of drying plant, more particularly, relates to the rotary mud dryer of a kind of single passage.
Background technology:
The water resources of China is very nervous, and the pollution situation of water resources is extremely serious.Mud is the solid waste in the water treatment procedure, has concentrated a large amount of bacteriums, pathogenic agent, the hazardous and noxious substances in the water body, deals with improperly and can cause serious secondary pollution.The mud of discharging from sewage work is because the water content height is bulky, and easily corrupt smelly, is unfavorable for transportation and disposes, and need dewater and reduce the water ratio of mud, reduces the volume of mud, reduces transportation cost, is beneficial to the follow-up disposal and the utilization of mud.
The running expense of sludge treatment part accounts for the 30-50% of the total running expense of Sewage Plant.At present domestic sludge filter cake water ratio after belt filter press is handled if reduce the water ratio of sludge filter cake, can be saved the operating cost of Sewage Plant to a great extent about 70%.Therefore, press for a kind of device that can improve reduction sludge filter cake water ratio, thereby reach the purpose of costs such as reducing mud subsequent transportation, processing.
Dryer need solve following problem:
1, mud has characteristics such as certain viscosity, granularity are little, easy conglomeration caking in the mud drying course.Enter at mud and to adhere to cylindrical shell in the process of dryer easily and occur piling up putty, influence the normal operation of dryer, lowered drying efficiency.
2, the sludge filter cake heating is inhomogeneous, can't control the sludge filter cake water ratio accurately.
3, the easy agglomerating caking of sludge filter cake, in cylinder with hot gas flow contact and stirring efficiency not high, drying efficiency is low.
The utility model content:
The utility model is exactly at the problems referred to above, provides a kind of single passage rotary mud dryer.
In order to realize above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, comprise belt filter press, conveyor, feed end seat, cylinder, filter, induced draft fan, burner, discharge end seat, carrying roller, speed reduction unit, motor, limiting roll, scraper agitator and scraper blade, conveyor is by the feed end seat, and link to each other with the discharge end seat through cylinder, induced draft fan links to each other with cylinder by filter, motor links to each other with carrying roller, cylinder successively by speed reduction unit, scraper agitator and scraper blade are positioned at cylinder, and limiting roll is arranged on the side of cylinder.
Described feed end seat and discharge end seat and cylinder flexibly connect.
Described discharge end seat is provided with burner; Can control filter cake moisture content by regulating the burner flame size, to satisfy different purposes such as its landfill, recovery.Increase burner flame and can reduce filter cake moisture content.Otherwise filter cake moisture content increases.
The number of described carrying roller is 4, and 2 is one group, is arranged at the both sides of cylinder respectively; The number of described limiting roll is 2; Four carrying roller back-up rollers and frictionally rotate cylinder continuously, the axial location of two limiting rolls restriction cylinders.
Described strainer is made up of multistorey strainer mesh and gas-liquid separator, and filter screen is used for impurity screening, and gas-liquid separator is used to filter water and steam.
Described scraper agitator is that arc is arciform, three stirring arm formation 3-D triangle different in size shapes.
Described scraper blade is " L " shape.
Two carrying rollers of the same side are driven by same motor and speed reduction unit, make these two carrying rollers turn to identical and synchronization by geartransmission.
The beneficial effects of the utility model:
The utility model is mainly used in the mud that chemistry, chemical industry etc. are full of the serious environmental pollution of plurality of heavy metal, perhaps is used for the recovery of noble metal etc.
Scraper agitator in the cylinder constantly carries out sludge filter cake fragmentation, stirs and scrapes, can prevent that like this mud from adhering to cylindrical shell and piling up putty, simultaneously, it has played the effect of smashing to mud group ball, it can fully be contacted with warm air with the burner flame of adverse current, improved rate of drying, become low-moisture bulk material behind the last drying sludge, discharged by the discharge end seat.
This device can be controlled filter cake moisture content by regulating the burner flame size, to satisfy different purposes such as its landfill, recovery.Increase burner flame and can reduce filter cake moisture content.Otherwise filter cake moisture content increases.
The sludge filter cake homogeneous heating, resulting filter cake moisture content unanimity.
