Example Embodiment

[0043] Examples:

[0044] A two-phase flow urban sludge treatment device, refer to figure 1 , Which includes a wet mud bin 11, a drying bin 12, and a dry mud bin 13 connected in sequence. The wet mud bin 11 is connected to the drying bin 12 through a feed pipe 14, and the drying bin 12 is connected to the dry mud bin 13 through a discharge pipe 15. A flue gas inlet 16 and a flue gas outlet 17 are respectively penetrated and welded on the side walls at both ends of the drying chamber 12.

[0045] Reference figure 2 , The drying bin 12 is provided with an extruding device 2 under the feed pipe 14, and the drying bin 12 is provided with a feeding device 3 under the extruding device 2.

[0046] Reference image 3 , The inner top wall of the drying chamber 12 is symmetrically provided with sliding grooves 210 on both sides of the feed pipe 14, the sliding groove 210 is fitted with a sliding block 21 connected to it, and the cross section of the sliding block 21 is T-shaped. The squeez...

Abstract

The invention discloses a two-phase flow municipal sludge treatment device, relates to the technical field of sludge treatment equipment, and aims to solve the technical problem of low drying efficiency. The invention adopts the key points of the technical scheme that an extrusion device and a feeding device are arranged in a drying bin; the extrusion device comprises a pair of extrusion rollers symmetrically arranged on the two sides under a feeding pipe, a gap is reserved between the two extrusion rollers, the extrusion rollers are rotationally connected with the inner wall of the drying bin, and extrusion drive parts for driving the extrusion rollers to rotate are fixedly arranged on the inner wall of the drying bin; the feeding device comprises a plurality of pairs of feeding rollers,the feeding rollers are rotationally connected with the inner wall of the drying bin, a feeding drive part for driving the feeding rollers is fixedly arranged on the inner wall of the drying bin, feeding conveyer belts are arranged on the outer sides of one pair of feeding rollers in a surrounding manner, and the adjacent feeding conveyor belts rotates in opposite directions and are distributed ina staggered manner in the vertical direction; sludge is extruded into a narrower sheet shape and is transported in the drying bin for a long time through the plurality of feeding conveyor belts, therefore, the drying efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of sludge treatment equipment, more specifically, it relates to a two-phase flow urban sludge treatment device. Background technique [0002] The two-phase flow municipal sludge treatment device is a device that separates sludge from water and mud. [0003] A kind of two-phase flow municipal sludge treatment device in the prior art refers to Figure 8 As shown, it includes a wet mud bin 11, a drying bin 12 and a dry mud bin 13 connected in sequence, the wet mud bin 11 communicates with the drying bin 12 through a feed pipe 14, and the drying bin 12 communicates with the drying bin through a discharge pipe 15. The mud bin 13 is connected, and the side walls at both ends of the drying bin 12 are respectively pierced with a flue gas inlet 16 and a flue gas outlet 17 , and the flue gas outlet 17 is connected to a condenser 18 . When in use, the sludge in the wet mud bin 11 enters the drying bin 12 from the feed...
