Abstract
The utility model relates to a high-efficiency indirect sludge drying device, which comprises a cylinder, an air inlet chamber and an air outlet chamber, wherein the cylinder is arranged transversely and provided with an interlayer, and the air inlet chamber and the air outlet chamber are respectively arranged at two ends of the cylinder and communicated with the interlayer. The high-efficiency indirect sludge drying device is characterized in that a conveying screw with inside hollow is transversely arranged in the cylinder, and a helical conveying mandrel which is used for forming a helical air passage and in linkage with the screw is arranged in an inner cavity of the conveying screw. The indirect sludge drying device is high-efficiency, low-pollution, high-productivity and low-cost. Heat exchange rate can be increased effectively so that sludge drying effect can be improved. The structure of the indirect sludge drying device is simplified due to the air inlet mode thereof, and accordingly manufacturing cost of the indirect sludge drying device is decreased.
Description
Technical field
The utility model relates to a kind of efficient indirect type mud drying unit, is applicable to mud is carried out the pre-treatment operation.
Background technology
Sludge incineration at present is one of best practical technology in the sludge treatment, but because the water ratio height (80%) of mud, calorific value is low, and directly burning needs to add a large amount of auxiliary fuels, running cost height.Drying system before burning is to reduce the water ratio of mud, makes it to improve sludge calorific value.But common spiral drying plant exists air input little, and thermo-efficiency is low, sludge dewatering poor effect, and the defective that exists high-pressure hot gas that the drying plant burn into is easily revealed.Therefore, at the problems referred to above be the purpose of the utility model research.
Summary of the invention
The purpose of this utility model is to provide a kind of efficient indirect type mud drying unit, helps promoting drying effect and reduces pollution.
Of the present utility model being characterised in that: a kind of efficient indirect type mud drying unit, comprise horizontal laying and have the cylindrical shell of intraformational bed and be located at cylindrical shell two ends and inlet plenum that is connected with intraformational bed and discharge chamber, it is characterized in that: also laterally be laid with the feeding spiro rod of inner hollow in the described cylindrical shell, be provided with helical feed mandrel in the inner chamber of described feeding spiro rod in order to form helical intake and to link with screw rod.
Advantage of the present utility model: the utility model device high-level efficiency, low pollution, high production capacity, low cost, can effectively improve rate of heat exchange, the drying effect of mud is improved, and intake method simplified the equipment structure, reduced the device fabrication cost.

Fig. 2 is the utility model embodiment spoiler laying structure synoptic diagram.
Embodiment
With reference to figure 1 and Fig. 2, a kind of efficient indirect type mud drying unit, comprise horizontal laying and have the cylindrical shell 1 of intraformational bed 2 and be located at cylindrical shell 1 two ends and inlet plenum 3 that is connected with intraformational bed 2 and discharge chamber 4, also laterally be laid with the feeding spiro rod 5 of inner hollow in the described cylindrical shell 1, be provided with helical feed mandrel 6 in the inner chamber of described feeding spiro rod 5 in order to form helical intake and to link with screw rod 5.
One end of above-mentioned feeding spiro rod 5 is provided with the inlet mouth 5-1 that is connected with inlet plenum 3, and the other end is provided with the air outlet 5-2 that is connected with discharge chamber 4.
Table is provided with refractory materials 7 in the above-mentioned inlet plenum 3, and the upper end is provided with high-temperature gas inlet mouth 3-1.
Table is provided with refractory materials 7 in the above-mentioned discharge chamber 4, and the side is provided with high-temperature gas air outlet 4-1.
Above-mentioned cylindrical shell 1 top is provided with sludge inlet 8 and waste gas air outlet 9, and the bottom is provided with mud discharge port 10.
Above-mentioned feeding spiro rod 5 drives rotation by the sprocket wheel 11 of being located at an end.
Above-mentioned cylindrical shell intraformational bed 2 is provided with the spoiler 12 of laying and being uniformly distributed along the circumference at interval vertically.
The specific implementation process is as follows:
The high temperature air inlet plenum is set, is provided with inlet mouth above inlet plenum, this form gas-storing capacity is big, has also solved turnover gas simultaneously and has connected, seals a difficult problem, and atm number is convenient to carry high temperature air to helical feed mandrel and intraformational bed.Insulation form high insulating effect in air chamber adopts.The helical feed mandrel has inlet mouth at axle head air chamber place, and this intake method has overcome with the screwed union air input little, the defective of high temperature element easy to wear, and inlet mouth need not sealing.The intraformational bed air flue is provided with spoiler, and every 2 meters layings, every circumferentially 12 again of the spoilers of 2 meters layings, spoiler has improved the turbulence level of gas to spoiler along axis direction, and the rate of heat exchange of the high temperature air by shell combination is improved.Helical intake places in the helical feed mandrel, and high-temperature gas has increased turbulivity along helicoidal flow, has improved rate of heat exchange.Be provided with the air outlet at the discharge chamber left surface.Establish sludge inlet on the cylindrical shell upper left side, the lower right is provided with the mud discharge port, and middle two air outlets produce the outlet of waste gas for the mud drying course.
The utility model drying unit adopts special structure formation, and the intraformational bed cylindrical shell of dress mud and the screw rod of carrying mud and inner chamber to be provided with the helical feed mandrel can lead to high temperature air simultaneously, make its high temperature air carry out indirect heat exchange with mud abundantly; The built-in helical intake of helical feed mandrel, intraformational bed are equipped with spoiler and have improved rate of heat exchange again, and the drying effect of mud is improved.Intake method has been simplified the equipment structure, has reduced the device fabrication cost.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
