Problems solved by technology

Although this type of dehydrator has many advantages, its defects are also very obvious. The dehydrator is assembled from several single-piece movable rings and fixed rings. The movable ring is easily damaged, which shortens the service life of the whole machine. shortened, the average lifespan is only about 5000 hours
When the traveling ring is worn to a certain extent, the machine will not be able to give full play to its processing capacity, which will affect the processing effect

Embodiment Construction

[0015] The snail stack sludge dewatering machine of the present invention will be further described below in conjunction with the accompanying drawings, taking 4 groups of laminated modular snail stack sludge dewatering machines as an example.

[0016] Such as figure 1 As shown, a laminated modular screw stack sludge dewatering machine mainly includes a shell 3, a dewatering cylinder 14 composed of a swimming ring 1, a fixed ring 2 and a screw propeller 15, a mud inlet 5, an outlet Mud port 10, speed-regulating motor 9, sleeve pipe 13 and filtrate recovery device 11. A number of fixed rings 2 are arranged sequentially inside the laminated module 6, a movable ring 1 concentric with the fixed ring 2 is arranged between adjacent fixed rings 2, a filtrate recovery device 11 is arranged at the bottom, and a screw propeller 15 runs through the fixed rings 2 and inside the moving ring 1, the laminated modules 6 are detachable and interchangeable.

[0017] Such as figure 2 Shown i...

Abstract

The invention discloses a volute sludge dewaterer, comprising a shell and a filtrate recycling device. The volute sludge dewaterer is characterized by comprising a spiral propeller arranged above the filtrate recycling device, a plurality of groups of lamination modules are sleeved on the spiral propeller and connected with each other and form a dewatering cylinder together with the spiral propeller, one end of the dewatering cylinder is provided with a sludge inlet, and the other end thereof is connected with a sludge outlet; and the spiral propeller is internally provided with a spiral shaft, and the shaft end thereof is fixedly connected with a variable frequency motor. By utilizing a modularized lamination assembling mode, the invention is beneficial for maintenance and adjustment of a traveling ring and prolongs the service life of the whole machine.

Description

technical field [0001] The invention relates to a sludge treatment device, which belongs to a screw stack sludge dehydrator. Background technique [0002] The screw stack sludge dewatering machine of the prior art can be widely used in the following fields: (1) organic and inorganic sludge generated in the wastewater treatment process of various industries; Separation of liquid; and (3) relying on this type of dehydrator, the rotating ring and the fixed ring are relatively moved by the rotary motion of the screw propeller, and at the same time, the gap of the filter part is cleaned to prevent clogging. Although this type of dehydrator has many advantages, its defects are also very obvious. The dehydrator is assembled from several single-piece movable rings and fixed rings. The movable ring is easily damaged, which shortens the service life of the whole machine. shortened, the average lifespan is only about 5000 hours. When the traveling ring is worn to a certain extent, th...
