Abstract
The utility model discloses a roller drier for a device for preventing wall sticking, which is mainly used for drying sludge which is dewatered via a machine. Because a plurality of loop chains are uniformly arranged on the front half part of the inner wall of a roller body, a ring can repeatedly strike sludge on the in the process of the rotation of the roller, and the problems of wall sticking, caking, and jamming in the drying process due to the large viscidity of the sludge and high water content of the sludge can be effectively solved; the drying effect can be improved. Even for the sludge with the water content of 87 percents, the direct drying can be carried out.
Description
The utility model relates to a kind of drying equipment of material dewatering, particularly the cylindrical drier that dehydrates of the mud that sewage treatment plant is produced.
The mud that sewage treatment plant produces, after preliminary concentrating, moisture content is still about 96%, usually all will add organic polymer coargulator, the liquid ratio of viscosities of this flocculant is higher, therefore, mud is the thickness colloidal substance behind the mechanical dehydration, has increased difficulty for dry the disposal.Present universal roller drier, its barrel is welded with flight or lifting blade mostly, this drying machine directly carries out drying to the mud that is thick behind mechanical dehydration, water content is very big, in dry run, problems such as sticking wall, caking, obstruction often appear, therefore, mud behind mechanical dehydration, must in special conveying and mixing apparatus, mix, could carry out drying to it to reach about 50% solid content with the backflow sludge-drying.
The purpose of this utility model exactly in order to overcome the weak point that existing interchangeable drum drying machine is used for drying sludge, provides a kind of mud behind mechanical dehydration is directly carried out drying and need not mix the drum-type sludge drier of siccative mix.
The utility model is realized by following proposal.The utility model comprise the inner vertical broken shaft that is provided with of barrel, barrel and go up the feeding mouth of the broken agitator of many rows of welding, barrel front end, with the close-connected hot-blast stove of barrel, the discharging opening that is positioned at the barrel rear end, air-vent, barrel first half inwall is the some loop chains of welding evenly, the latter half of inwall of cylinder is the some flights of welding evenly, the preferred belt transport unit of pay-off before the feeding mouth.
The effect that the inboard first half of this dry machine cylinder body is provided with loop chain is in dry run, along with the cylinder rotation, loop chain is the mud of pummel adhesion on barrel repeatedly, not only can prevent to occur wall sticking phenomenon because of sewage sludge viscosity is too high, and can break up caking, and heat passed to mud by direct contact, itself and hot blast contact area are strengthened, quicken its water evaporates, improved drying effect, solved mud sticking wall, caking and blockage problem, saved conveying and mixing apparatus, thereby reduced equipment investment and floor space.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the longitudinal sectional view of a specific embodiment of the present utility model.
Fig. 2 is the transverse sectional view of Fig. 1.
Claims (3)
1. drum-type sludge drier, comprise the inner vertical broken shaft that is provided with of barrel, barrel and go up the broken agitator of many rows, the barrel front end of welding feeding mouth, with the close-connected hot-blast stove of barrel, the discharging opening that is positioned at the barrel rear end, air-vent, it is characterized in that the evenly some loop chains of welding of barrel first half inwall, the latter half of inwall of cylinder is the some flights of welding evenly.
2. drying machine according to claim 1 is characterized in that barrel first half inwall radially and axially evenly welds some loop chains respectively.
3. drying machine according to claim 1 is characterized in that the preceding pay-off of feeding mouth of drying machine is a belt transport unit.
