Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, in particular to a decomposition device for sludge treatment. Background Art

[0002] Sludge treatment is an important part of sewage treatment, and its purpose is to reduce, stabilize and harmlessly treat sludge. With the improvement of environmental protection requirements and the enhancement of awareness of resource recycling, traditional sludge treatment methods, such as landfill and incineration, have gradually failed to meet the needs of modern society due to their large environmental impact and waste of resources.

[0003] The water in the sludge can be used for agricultural irrigation after simple treatment. However, the existing sludge treatment equipment is all aimed at how to filter the water to be pure, which affects the efficiency of sewage recycling. Therefore, we propose a sludge treatment decomposition device to solve the above technical problems. Summary of the invention

[0004] In view of this, the present invention lacks needles, and its main purpose is to provide a decomposition device for sludge treatment, which serves to solve the above-mentioned problems.

After the sludge enters the inner side of the device, it comes to the inner side of the third separation cylinder. At this time, the stirring mechanism inside the third separation cylinder beats and stirs the sludge to improve the dispersibility of the sludge. When the sludge accumulates at the third penetration hole of the third separation cylinder, the water in the sludge is separated for the first time through the third penetration hole, so that the water enters the outside of the third separation cylinder. After the sludge enters the outside of the third separation cylinder, it enters the outside of the second separation cylinder through the second penetration hole. The separated water is separated through the second The infiltration hole enters the inner side of the first separation cylinder, and the sewage is separated for the second time. Then, when the water overflows to the first infiltration hole, the water overflows to the inner side of the first separation cylinder and the outer cylinder through the first infiltration hole, and the third separation is completed.

[0007] When the sludge is used for land irrigation and excessively pure water is not needed, only the third discharge component needs to be closed. At this time, the water in the sludge will flow out directly from the second discharge component without the need for a third filtration, so that the device can be used according to the needs of the user, enhancing the user experience.

[0012] As a preferred solution, the second material discharge assembly includes a second guide bucket fixedly installed at the bottom of the second separation cylinder, a second guide pipe fixedly installed at the bottom of the second guide bucket, a second piston ring inserted into the outer side of the second guide pipe, a second push-pull rod fixedly installed on the second piston ring, and a second push-pull curved plate fixedly installed on the second push-pull rod.

[0016] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that it mainly has the following advantages:

[0017] In this device, when sludge accumulates to the third permeation hole of the third separation cylinder, water in the sludge is separated for the first time through the third permeation hole, so that the water enters the outside of the third separation cylinder. After the sludge enters the outside of the third separation cylinder, it enters the outside of the second separation cylinder through the second permeation hole. The separated water enters the inside of the first separation cylinder through the second permeation hole. At this time, the sewage is separated for the second time. Subsequently, when the water overflows to the first permeation hole, the water overflows to the inside of the first separation cylinder and the outer cylinder through the first permeation hole, thus completing the third separation.

After the device completes the treatment of a batch of sludge, the sludge inside the third separation cylinder and between the second separation cylinder and the third separation cylinder is discharged by opening the third discharge assembly and the second discharge assembly.

[0019] When the sludge is used for land irrigation and does not require extremely pure water, the third discharge component can be closed. At this time, the water in the sludge will flow out directly from the second discharge component without the need for a third filtration, so that the device can be used according to the needs of the user and the utilization rate of sewage can be improved.

[0020] During the process of stirring and beating the sludge by the stirring mechanism through the injection mechanism arranged on the top cover, cationic polyacrylamide diluted with water is sprayed into the interior of the outer sleeve to decompose the sludge, thereby separating the water in the sludge.
