Embodiment Construction

[0019] Referring to Fig. 1, according to a preferred embodiment provided by the present invention, it includes a box body 1, a heating device 2 installed in the box body 1 and a drying conveyor belt 3, and the box body 1 is provided with a feeding port 11 and a discharge port 12, the sludge extrusion drum 4 is installed at the feed port 11. In the present invention, a sludge extruding roller 4 is arranged at the feeding port of the box body 1, and the blocky sludge entering the box body 1 is squeezed by the sludge extruding roller 4, and the sludge is extruded into thin slices. This flaky sludge is good for drying, which can greatly reduce the drying time, thereby shortening the length of the entire drying equipment. At the same time, the sludge extruding drum 4 can extrude a part of excess moisture in the sludge, which is also beneficial to subsequent drying.

[0020] Referring to FIG. 1 , in the above-mentioned embodiments of the present invention, the box body 1 is provide...

Abstract

The invention discloses a sludge drying equipment, which comprises a box, a heating device arranged in the box and a drying conveyer belt, wherein, the box is provided with a feed inlet and a discharge hole, and a sludge extruding roller is arranged at the feed inlet. In this invention, a sludge extruding roller is arranged at the feed inlet of the box, which can extrude the sludge that goes into the box, so that the moisture of the sludge removed and the sludge can be pressed into slice. The sludge pressed into slice is tiled on the drying conveyer belt, which is beneficial to the heating device to heat the sludge and can reduce the drying time of the sludge, thereby reducing the drying equipment, saving large amount of resource and reducing environment pollution.

Description

technical field [0001] The invention relates to a drying device, in particular to a drying device for sludge. Background technique [0002] In the prior art, such as Chinese Patent No. 02254415.1 utility model patent, its announcement date is September 23, 2003, and its announcement number is CN2570717, which discloses a drum type sludge dryer, which at least includes: a base , a roller device, a driving device, a discharge device and a hot air input device, which are characterized in that: the base has a platform structure for the roller device to be rotatably laid and rolled; the roller device is a set On the base, the double-opened cylinder that turns over the sludge and supplies hot air into the drying chamber is provided with vertical plates around the inner wall of the cylinder, and horizontally extending partitions are respectively installed on the same side of each vertical plate. The front end of the plate is provided with an inward bending piece to form a drum dev...
