Embodiment 1

[0042] like figure 1 As shown in the figure, this embodiment provides a sludge drying and feeding device, including a de-cemented cake conveyor belt 1, and a sludge-blocking device 3 on the de-cemented cake conveyor belt 1, and the sludge-blocking device 3 is a fork with spikes 2 Type structure, the deconsolidated cake is divided into blocks, which is convenient for subsequent processing. The dewatered cake conveyor belt 1 is a chain conveyor belt, and the chain conveyor belt is conveyed by a chain conveyor. There is a toggle device 5 at the end of the decalcified cake conveyor belt 1 to prevent the dehydrated cake from being too viscous and unable to fall into the lower hopper. The toggle device 5 is a turntable structure with a plurality of toggles.

[0043] At the end of the chain conveyor belt, the gap between each segment of the chain and the chain forms a gap, and the assembly position of the toggle device is satisfied. The shortest distance between the entire toggle d...

Embodiment 2

[0050] This embodiment provides a sludge drying and feeding method, which is carried out in the sludge drying and feeding device shown in Embodiment 1. It includes the following steps: placing the deconsolidated cake on the deconsolidated cake conveyor belt 1, the deconsolidated cake moves with the deconsolidated cake conveyor belt 1, and falls into the lower hopper 6 at the end of the dehydrated cake conveyor belt, and enters the dilute phase conveying along the outlet of the lower hopper 6. Pipe 8, start the fan 7, divide the de-cemented cake into small pieces of sludge, enter the gas-material separation device 9 along the dilute phase conveying pipeline 8, the sludge is discharged from the sludge outlet of the gas-material separation device 9, and the gas is separated from the gas material The gas outlet of the device 9 goes out and enters the suction device 10 . Start the windmill 11, the windmill 11 rotates to provide wind power, the sludge is thrown out along the tangent...

Embodiment 3

[0056] This embodiment provides a sludge drying and feeding method, which is carried out in the sludge drying and feeding device shown in Embodiment 1. It includes the following steps: placing the deconsolidated cake on the deconsolidated cake conveyor belt 1, the deconsolidated cake moves with the deconsolidated cake conveyor belt 1, and falls into the lower hopper 6 at the end of the dehydrated cake conveyor belt, and enters the dilute phase conveying along the outlet of the lower hopper 6. Pipe 8, start the fan 7, divide the de-cemented cake into small pieces of sludge, enter the gas-material separation device 9 along the dilute phase conveying pipeline 8, the sludge is discharged from the sludge outlet of the gas-material separation device 9, and the gas is separated from the gas material The gas outlet of the device 9 goes out and enters the suction device 10 . Start the windmill 11, the windmill 11 rotates to provide wind power, the sludge is thrown out along the tangent...

Abstract

The disclosure relates to the field of sludge treatment, and specifically provides a sludge drying and feeding device and a feeding method. The sludge drying and feeding device includes a dehydrated cake conveyor belt, a lower hopper located at the end of the dehydrated cake conveyor belt, the outlet of the lower hopper is connected at a certain angle with the dilute-phase conveying pipeline, and there is a fan at the entrance of the dilute-phase conveying pipeline, and the outlet of the dilute-phase conveying pipeline is There is a gas-material separation device, the gas outlet of the gas-material separation device is connected to the suction device, and a windmill is installed at the sludge outlet of the gas-material separation device. It solves the problem that the moisture content of the dehydrated cake is high, it is easy to block the conveying pipeline, and it is difficult to distribute evenly in the sludge drying device.

Description

technical field [0001] The present disclosure relates to the field of sludge treatment, and specifically provides a sludge drying feeding device and a feeding method. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the development of my country's social economy, the acceleration of urbanization and the improvement of people's living standards, the amount of urban domestic sewage has increased sharply. As a subsidiary product of sewage treatment in sewage treatment plants, sludge is rich in organic humus, bacterial cells, parasite eggs and heavy metals and other harmful substances. It is a potential secondary pollution source, which has a great impact on the environment. With the sharp increase of sludge production, more and more attention has been paid to the disposal of sludge. [0004] Traditional sludge treatment methods include stable ...
