Movable type high-performance integrated machine for sludge treatment

Abstract

The invention discloses a movable type high-performance integrated machine for sludge treatment, and belongs to the field of sludge treatment equipment technology. The integrated machine is composed of a stacked spiral sludge dewatering machine, a doser, and a sludge conveyer; an outlet of the doser and an outlet of the sludge conveyer are connected to an inlet of the stacked spiral sludge dewatering machine. The integrated machine for sludge treatment employs the stacked spiral sludge dewatering machine with low operation cost, and the cost is less than 40% of the operation cost of a belt filter press and is less than 20% of the operation cost of a centrifugal hydroextractor; the integrated machine saves power, and the consumed electricity is less than 5% of the consumed electricity of a centrifuge; the integrated machine saves water, and the consumed water is less than 0.1% of the consumed water of the belt filter press; the integrated machine saves chemical medicines, and saves 60% of chemical medicines on average; the integrated machine has a small volume, a dehydration machine room saves 60% or above of the investment, a modifier does not change original properties of the sludge, the machine has effects for removing ova of roundworm and fecal coliform in the sludge, and the machine has a stabilization effect for heavy metals.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment equipment, and in particular relates to a mobile high-efficiency sludge treatment integrated machine. Background technique [0002] There are mainly 4 kinds of sludge dewatering machines in the prior art market: belt filter press, plate and frame filter press, centrifugal dewatering machine and stacked screw sludge dewatering machine. These 4 kinds of sludge dewatering machines each have their own advantages and disadvantages. Disadvantages: The centrifugal dehydrator uses the principle of centrifugal sedimentation to separate the solid from the liquid. Since there is no filter screen, it will not cause clogging, while the belt filter press uses the filter belt to separate the solid from the liquid. In order to prevent the filter belt from clogging, high-pressure water needs to be continuously washed ; The centrifuge is suitable for the concentration and dehydration of all kinds of sludge...

AI Technical Summary

Problems solved by technology

The power consumption of the centrifuge per cubic meter of sludge dewatering is 1.2kW / m 3 , the noise during operation is 76-80db, and it runs continuously for 24 hours a day. Except for shutdown, no cleaning water is needed during operation; while the power consumption of sludge dehydration per cubic meter of belt machine is 0.8kW / m3, and the noise during operation is 70~75db , the filter cloth needs to be loosened and maintained. Generally, only two shifts are arranged for operation every day. During the operation, the filter cloth needs to be continuously washed with high-pressure water; the centrifuge occupies a small space and is easy to install and debug. The machine is fully sealed, and the workshop environment is good; while the belt machine occupies a large area, and the supporting equipment needs to be flushing pumps, air compressors, sludge conditioners, etc. in addition to the dosing and feeding and discharging conveyors, and the airtightness of the whole machine is poor. High-pressure cleaning water mist and odor pollute the environment, if the management is not good, it will cause mud to overflow
