Technical Field
[0001] This utility model belongs to the technical field of sludge treatment equipment, specifically a sludge treatment device. Background Technology
[0002] In today's society, with the acceleration of urbanization and continuous industrial development, the volume of sewage treatment is increasing daily, and the output of sludge, as a byproduct of sewage treatment, is also increasing dramatically. Sludge typically contains large amounts of toxic, harmful, or environmentally harmful substances, such as heavy metals, pathogens, and organic pollutants. If not properly treated, it will cause serious secondary pollution to the ecological environment. Therefore, the effective treatment of sludge has become an important issue that urgently needs to be addressed in the field of environmental protection.
[0003] A search revealed Chinese patent application number 202320697304.2, which discloses a sludge treatment device. The device includes a sludge storage tank with a sealing mechanism on its surface, a discharge structure on its surface, and a power supply device on its surface. This invention, through the cooperation of the discharge structure and power supply device, allows workers to manipulate the power supply device to rotate the sludge storage tank during dewatering, thereby quickly dumping the sludge out. This solves the problem in existing devices where, to prevent dewatered sludge from scattering from the scraper, workers have to intermittently move the scraper upwards to collect the sludge. This method not only increases the workload of workers but also wastes time and affects dewatering efficiency.
[0004] Although the aforementioned patent allows workers to operate the power supply device to rotate the sludge storage tank and quickly dump the sludge out when removing the dewatered sludge, in actual use, when dewatering by centrifugal force, the sludge easily enters the gap between the sludge storage tank and the dewatering screen cylinder from the top of the sludge dewatering component, which can easily cause blockage of the drainage pipe. Moreover, centrifugal dewatering alone has a poor dewatering effect, affecting dewatering efficiency and effectiveness.
[0005] Therefore, it is necessary to modify it by setting up a squeezing plate to seal the top of the centrifuge cylinder, so as to prevent sludge from entering the interlayer and affecting dewatering. At the same time, after centrifugation and dewatering, the sludge is squeezed to carry out secondary dewatering, thereby improving the dewatering effect and efficiency. Utility Model Content
[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a sludge treatment device that features a sealing mechanism by a compression plate to prevent sludge from entering the interlayer and affecting dewatering. Simultaneously, after centrifugal dewatering, the sludge is compressed for secondary dewatering, improving dewatering effect and efficiency. This solves the problems in the prior art where, during centrifugal dewatering, sludge easily enters the interlayer between the sludge storage tank and the dewatering screen cylinder from the top of the sludge dewatering component, leading to drainage pipe blockage. Furthermore, centrifugal dewatering alone results in poor dewatering efficiency and effectiveness.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a sludge treatment device, comprising a base plate, with side plates fixedly connected to the left and right sides of the top of the base plate, and a treatment box disposed on the inner side of the two side plates. A reduction motor is fixedly connected to the right side of the right side plate via a support plate, and the output end of the reduction motor passes through the inner side of the side plate and is fixedly connected to the right side of the treatment box. The left side of the treatment box is rotatably connected to the right side of the left side plate. A first electric telescopic rod is fixedly connected to both the left and right sides of the treatment box, and a top cover is fixedly connected to the top of the first electric telescopic rod. The bottom of the top cover fits into the top of the processing box. A centrifuge cylinder is installed inside the processing box. Several evenly distributed drainage grooves are opened on the surface of the centrifuge cylinder, and a detachable filter screen plate is fixedly connected to the inside of the drainage groove by bolts. A square groove is opened in the center of the top cover, and a second electric telescopic rod is fixedly connected inside the square groove. The output end of the second electric telescopic rod extends into the inside of the processing box and is rotatably connected to a pressing plate. A drive motor is fixedly connected to the bottom of the processing box, and the output end of the drive motor passes through the inside of the processing box and is fixedly connected to the bottom of the centrifuge cylinder.

[0034] The working principle and usage process of this utility model are as follows: In use, the top cover 6 is raised by the first electric telescopic rod 5 to open the top of the processing tank 3, and the sludge to be treated is put into the centrifuge cylinder 7. Then, the first electric telescopic rod 5 drives the top cover 6 to descend, so that the top cover 6 is tightly fitted with the processing tank 3. The sealing gasket 15 ensures good sealing performance. At the same time, the squeezing plate 10 is inserted into the centrifuge cylinder 7, and its outer side is fitted with the inner wall of the centrifuge cylinder 7 through the sealing piston ring, sealing the top of the centrifuge cylinder 7. Next, the dewatering treatment stage begins. First, the drive motor 11 is started to drive the centrifuge cylinder 7 to rotate at high speed. Centrifugal force is used to throw the water in the sludge into the processing tank 3 through the drain trough and filter screen 8, and discharge it from the drain valve pipe to achieve preliminary dewatering. After centrifugal dewatering is completed, the second electric telescopic rod 9 pushes the squeezing plate 10 downward to squeeze the sludge in the centrifuge cylinder 7, further dewatering and improving the dewatering effect. During the sludge discharge stage, the second electric telescopic rod 9 retracts, the squeezing plate 10 rises, and the first electric telescopic rod 5 raises the top cover 6 again, moving the squeezing plate 10 away from the centrifuge drum 7. Then, the reduction motor 4 is started to drive the processing tank 3 to rotate, dumping out the processed sludge. Finally, in the cleaning and maintenance stage, the cleaning brush 17 automatically cleans the sludge from the surface of the centrifuge drum 7 during the processing. After processing, the filter screen plate 8 and cleaning brush 17 can be disassembled for cleaning or replacement as needed. At the same time, a comprehensive inspection of the equipment is carried out to ensure that the equipment is fault-free and to make full preparations for the next processing.
