Description

Technical Field

[0001] The present invention relates to the technical field of sludge dewatering treatment, and specifically to a method and device for sludge dewatering and solidification treatment. Background Art

[0002] The treatment methods of river silt mainly target cities. Studying the treatment means of urban river silt will provide important reference value for the treatment and disposal of rural river silt. Generally speaking, there are mainly four types of sludge produced in cities: construction slurry, river silt, sewage in ditches, and sludge from sewage treatment plants. Excluding construction slurry, river silt, sewage in ditches, and sludge from sewage treatment plants contain a large amount of pathogenic bacteria, parasites, heavy metals, and some difficult-to-degrade organic poisons. If not properly disposed of, it will cause secondary pollution to the environment.

[0003] A large amount of sludge with extremely high water content is generated during the sewage treatment process. For the treatment of sludge, it is generally concentrated and dehydrated successively. After the concentration treatment, the water content is still very high, and further dehydration is required to reduce the water content. The existing common dehydration methods mainly include natural drying and mechanical dehydration. When mechanically treating sewage, the separated soil will adhere to the inner wall of the separation cylinder and cause blockage of the separation cylinder. When sewage dehydration and solidification are not carried out, disinfected water needs to be introduced for sterilization and cleaning. It is impossible to sterilize and clean the separation cylinder while carrying out sewage dehydration and solidification, and separate operations are required, which increases the overall consumption time. Therefore, we provide a method and device for sludge dewatering and solidification treatment to solve the above problems. Summary of the Invention

[0013] A method for sludge dewatering and solidification treatment includes the following steps:

[0014] S1. First, the sludge conveying mechanism intermittently conveys sludge into the separation cylinder through the medicine inlet pipe. The hydraulic rod drives the guide frame to move leftward. The guide frame drives the extrusion plate to move. The extrusion plate drives the buffer rod to move under the action of the buffer spring. The buffer rod drives the push plate to extrude and separate the sludge.

[0015] S2. Then, the separated water flows into the collection cylinder. The water collection mechanism conveys part of the water into the disinfectant storage tank through the collection pipe respectively. While the hydraulic rod drives the guide frame to move, it also drives the moving frame. The moving frame drives the piston plate to move. The piston plate conveys the separated water and the water pre-stored in the disinfectant storage tank through the connecting pipe into the flushing integrated pipe on the right side of the separation cylinder. The flushing integrated pipe flushes the inner wall of the separation cylinder through the flush head.

[0016] S3. After the sludge extrusion is completed, the drive motor drives the rotating collar to rotate through the toothed ring. At the same time, the electromagnetic rod drives the adjusting frame to move, the adjusting frame drives the adjusting ring to move, the adjusting ring drives the pushing frame to rotate, the pushing frame drives the adjusting plate to rotate, and the adjusting plate cuts up the extruded mud cake.

[0017] S4. During the process of cutting up the mud cake, the buffer spring can drive the pushing plate to apply a thrust to the lumped sludge, which can assist in the crushing and discharging of the sludge. Under the action of the pushing plate and the buffer spring, the mud cake is completely cut up and discharged from the mud discharge port.

[0018] Compared with the prior art, the sludge dewatering and solidification treatment method and device have the following beneficial effects:

[0019] First, the external sludge conveying mechanism of the present invention intermittently conveys sludge into the separation cylinder through the medicine inlet pipe. The hydraulic rod drives the guiding frame to move leftward, the guiding frame drives the extrusion plate to move, the extrusion plate drives the buffer rod to move under the action of the buffer spring, the buffer rod drives the pushing plate to extrude and separate the sludge, and the separated water flows into the collection cylinder. The water collection mechanism conveys part of the water to the disinfectant storage tank through the collection pipe respectively. While the hydraulic rod drives the guiding frame to move, it also drives the moving frame, the moving frame drives the piston plate to move, and the piston plate conveys the separated water and the water pre-stored in the disinfectant storage tank to the flushing integrated pipe on the right side of the separation cylinder through the connecting pipe. The flushing integrated pipe flushes the inner wall of the separation cylinder through the flushing head, solving the problem that the existing device needs to introduce disinfected water for sterilization and cleaning when not performing sewage dewatering and solidification, and it is impossible to perform sterilization and cleaning of the separation cylinder while performing sewage dewatering and solidification, and it is impossible to perform separation, dehydration and solidification during the sterilization and cleaning. It has the advantage of simultaneously performing dehydration and solidification and sterilizing the inner wall of the cleaning mechanism.

[0020] Second, after the sludge extrusion of the present invention is completed, the drive motor drives the rotating collar to rotate through the toothed ring. At the same time, the electromagnetic rod drives the adjusting frame to move, the adjusting frame drives the adjusting ring to move, the adjusting ring drives the pushing frame to rotate, the pushing frame drives the adjusting plate to rotate, and the adjusting plate cuts up the extruded mud cake. Under the action of the pushing plate and the buffer spring, the mud cake is completely cut up and discharged from the mud discharge port, having the advantage of convenient cutting of the mud cake.

9. A method for sludge dewatering and solidification treatment, characterized in that The treatment device using any one of claims 1-8 includes the following steps: S1. First, the sludge conveying mechanism intermittently conveys sludge into the separation cylinder (1) through the chemical feeding pipe (11). The hydraulic rod (4) drives the guide frame (5) to move leftward. The guide frame (5) drives the extrusion plate (6) to move. The extrusion plate (6) drives the buffer rod (7) to move under the action of the buffer spring (9). The buffer rod (7) drives the push plate (8) to extrude and separate the sludge. S2. Then, the separated water flows into the collection cylinder (10). The water collection mechanism (33) conveys part of the water to the disinfectant storage tank (20) through the collection pipe (12). While the hydraulic rod (4) drives the guide frame (5) to move, it also drives the moving frame (21). The moving frame (21) drives the piston plate (22) to move. The piston plate (22) conveys the separated water and the water pre-stored in the disinfectant storage tank (20) to the flushing integrated pipe (17) on the right side of the separation cylinder (1) through the connecting pipe (19). The flushing integrated pipe (17) flushes the inner wall of the separation cylinder (1) through the flushing head (18). S3. After the sludge extrusion is completed, the drive motor (25) drives the rotating collar (23) to rotate through the toothed ring (24). At the same time, the electromagnetic rod (32) drives the adjusting frame (31) to move. The adjusting frame (31) drives the adjusting ring (29) to move. The adjusting ring (29) drives the pushing frame (28) to rotate. The pushing frame (28) drives the adjusting plate (27) to rotate. The adjusting plate (27) cuts up the extruded mud cake. S4. During the process of cutting up the mud cake, the buffer spring (9) can drive the push plate (8) to apply a thrust to the lumpy sludge, which can assist in the crushing and discharging of the sludge. The mud cake is completely cut up under the action of the push plate (8) and the buffer spring (9) and is discharged from the sludge discharge port.
