Embodiment 1

[0031] Such as Figure 1-7 Shown: a sludge drying device, including a frame system 1, a heating system 3 and a stirring system 2, the frame system 1 includes a lower support plate 101, a vertical pole 102, an upper support plate 103, there are four vertical poles 102, surrounded by Rectangular, the lower support plate 101 is positioned at the middle and lower part of the pole 102, the upper support plate 103 is positioned at the top of the vertical pole 102, the upper support plate 103 exceeds the rectangular area surrounded by the vertical pole 102, and the lower support plate 101 and the upper support plate 103 are provided with the same Shaft mounting holes;

[0032] The heating system 3 includes a steam inlet 301, a heating pipe 302, a steam exhaust port 303, and a baffle 304. The heating pipe 302 is detachably installed on the coaxial installation of the lower support plate 101 and the upper support plate 103. In the hole, the upper part of the heating pipe 302 is provid...

Embodiment 2

[0041] Other features are all described in Embodiment 1. In practical applications, 6 stirring blades 206 are evenly arranged inside the stirring shell 209, and the section of the baffle 304 is fan-shaped at 300 degrees. The rotation elevation angle of the 206 stirring blades is 75 degrees, related to the aspect ratio of the stirring shell 209, the distance between the outer edge of the stirring blade 206 and the outer wall of the heating tube 302 is 8 cm. .

[0042] In summary, the present invention can effectively prevent highly viscous organic sludge from adhering to the stirring system, improve drying efficiency, and reduce steam consumption during the working process.

Abstract

The invention belongs to the field of environmental engineering equipment, and particularly relates to a sludge drying device. The sludge drying device comprises a frame system, a heating system and astirring system, wherein the frame system comprises a lower support plate, vertical rods and an upper support plate; the heating system comprises a steam inlet, a heating pipe, a steam outlet and baffle plates, and notches formed by the baffle plates and the heating pipe are distributed at intervals; the stirring system comprises a stirring shell, sealing pipe joints, stirring blades, a driving chain, a driving motor, a chain wheel, sealing plates, a dry sludge discharge port and a sludge exhaust port, the chain wheel is arranged on the outer wall of the upper part of the sealing shell, and the driving motor drives the stirring shell to rotate through the driving chain; the sealing plates are installed on the heating pipe, the sludge exhaust port is formed in the upper sealing plate, andthe dry sludge discharge port is formed in the lower sealing plate. The device can effectively prevent organic sludge with higher viscosity from adhering to the stirring system, drying efficiency is improved, and the steam consumption in the working process is reduced.

Description

technical field [0001] The invention belongs to the field of environmental engineering equipment, and in particular relates to a sludge drying device. Background technique [0002] Sludge is the solid sedimentation material produced by water and wastewater treatment processes. Its main characteristics are: high moisture content up to 99%, high organic matter content, easy to rot and smell, and fine particles, small specific gravity, in a colloidal liquid state. According to the sources of sludge, there are mainly: domestic sewage sludge, industrial wastewater sludge and water supply sludge. The disposal and treatment of all kinds of sludge has become a chronic disease restricting urban development and urban sanitation. [0003] With the strengthening of national energy conservation and emission reduction efforts, the improvement of national environmental protection awareness, and the increasing output of urban sludge, sludge disposal and development and utilization issues ...
