A sludge conditioning device

Abstract

The present invention relates to the field of sludge treatment equipment, in particular to a sludge conditioning device, which includes a feeding screw conveyor, a transport mechanism and a discharge screw conveyor. The transport mechanism includes a driving component, a feeding component, a transport component, a transmission component and several mixing components, the driving component is installed on one side of the transport component and the two are connected by transmission, the feeding component is set on the upper end of the transport component, the transmission component is set on the other end of the transport component, and several stirring components are in the form of a circle Distributed in the transport component, and each mixing component is connected to the transport component through a transmission component, and a receiving component is arranged directly under the transport component. When the present invention is in use, it can continue to work, thereby improving the efficiency of sludge conditioning, and can filter out the separated sewage during the conditioning process, reducing the workload of subsequent sludge dehydration. The present invention It can also reduce the working intensity of the equipment and prolong the service life.

Description

technical field [0001] The invention relates to the field of sludge treatment equipment, in particular to a sludge conditioning device. Background technique [0002] A large amount of sludge will be produced in industrial production and sewage treatment, and these sludges will contain a large amount of water and organic matter. In order to improve the utilization rate of resources and reduce the impact of sludge on the environment, it is necessary to conduct in-depth sludge Dewatering, so that the water content of the sludge is less than 60%. In order to improve the dehydration performance of sludge, the sludge must be treated in the early stage, which is what we call "sludge conditioning".  The sludge is tempered before sludge dehydration to change the physical and chemical properties of sludge particles, destroy its colloidal structure, and reduce its affinity with water, thereby improving the dehydration performance of sludge. A commonly used method for sludge conditioni...

Problems solved by technology

[0004] Although the above-mentioned patent can realize automatic mixing of sludge and sludge conditioner, there are following deficiencies in actual use. First, the device needs to mix sludge and sludge conditioner in batches, each Quantitative work is required every time. During work, other sludge cannot continue to enter the equipment, and continuous work cannot be achieved, thereby reducing the mixing efficiency of sludge and sludge conditioner. Second, due to the high density of sludge, it will Increase the difficulty of stirring, and when the above-mentioned device is in use, it directly uses the motor to drive the stirring rod to stir the sludge, which is more difficult to work and increases the load of the motor, which will affect the service life of the equipment
