TECHNICAL FIELD
[0001] The utility model relates to the field of sludge bin, especially a sludge bin with sewage separation function. BACKGROUND
[0002] Sludge bin is an important component in sewage treatment facilities, mainly used for storing and treating sludge generated during the sewage treatment process. These sludge usually contains a large amount of organic matter and water, which needs to go through steps such as concentration, digestion, and dehydration to reduce volume and weight, and reduce its impact on the environment. The design and size of the sludge bin will vary depending on the scale and processing capacity of the treatment plant. In some designs, the sludge bin may also include a heating system to promote the digestion process of the sludge, and a stirring device to maintain the uniformity of the sludge.
[0003] In practical application, the sludge bin with sewage separation function usually uses the principle of sedimentation to realize the upper and lower layering of sludge. During the sedimentation process, the solid particles in the sludge gradually settle to the bottom, while the upper layer forms a relatively clear liquid. However, if the discharge rate of the upper liquid is too slow, it may lead to poor sedimentation effect, because the suspended matter in the liquid has enough time to resuspend, affecting the separation effect.
[0004] When trying to quickly discharge the upper liquid by pushing the plate, although the discharge rate can be improved, this approach often causes the liquid to fluctuate up and down, thereby stirring the already settled sludge layer. This stirring causes the originally layered sludge to remix, resulting in the upper liquid becoming turbid, thereby reducing the separation efficiency and water quality. SUMMARY
[0005] The main purpose of the utility model is to provide a sludge bin with sewage separation function, which can effectively solve the problems raised in the background art.
[0006] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is:
[0007] A sludge bin with sewage separation function, comprising a bin body and a sedimentation separation chamber, the upper end of the bin body is provided with a sedimentation separation chamber for sedimentation and separation of sludge;
[0008] A screw feeder is erected in the sedimentation separation chamber and installed on the bin body through a bearing device. One end of the bin body is provided with a speed reducer connected with the screw feeder. The outer end of the speed reducer is connected with a servo motor. The lower end of the bin body is provided with a sewage discharge pipe, and the other end of the bin body is connected with a liquid discharge pipe. The upper liquid in the sedimentation separation chamber is discharged from the liquid discharge pipe. The servo motor drives the screw feeder to move, and the sludge at the bottom of the sedimentation separation chamber is sent to the sewage discharge pipe to realize sewage discharge;
[0009] The other end of the bin body is connected with an electric push rod through a mounting block and a support frame, the telescopic end of the electric push rod is connected with a push plate through a connecting strip, and a filter gap is formed in the lower end of the push plate.
[0010] As a preferred scheme of the present application, a wave-preventing hole is formed in the end face of the push plate, and the upper liquid in the sediment separation cavity passes through the wave-preventing hole, thereby reducing excessive fluctuation of the liquid in the sediment separation cavity.
[0011] As a preferred scheme of the present application, the blowdown pipe and the liquid discharge pipe are fixed on the bin body, and a sealing ring is arranged at the connection between the blowdown pipe and the liquid discharge pipe and the bin body, the bearing device and the screw feeder are mechanically sealed with the bin body, and the bearing device is fixed on the bin body through bolts.
[0012] As a preferred scheme of the present application, the screw holes of the mounting block and the support frame are aligned with the round holes of the bin body, and the mounting block and the support frame are fixed on the bin body by means of bolts, nuts and anti-skid washers, and the support frame, the mounting block and the electric push rod are fixed by means of bolts.
[0013] As a preferred scheme of the present application, the connecting strip and the telescopic end of the electric push rod are fixed by means of bolts, the connecting strip and the push plate are fixed by means of bolts, and the side wall inclined surface of the push plate is adapted to the inner inclined surface of the bin body, thereby limiting the inclination of the push plate.
[0014] As a preferred scheme of the present application, the filter gap is designed in a zigzag shape, and the corner of the filter gap is designed in an arc shape.
[0015] Compared with the prior art, the present application has the following beneficial effects:
[0016] Through the cooperative work of the screw feeder and the electric push rod, we can realize effective separation of sludge and rapid blowdown, thereby significantly improving the efficiency of sewage treatment. The side wall inclined surface of the push plate is perfectly adapted to the inner inclined surface of the bin body, which limits the inclination of the push plate and ensures the stability of movement, effectively avoiding unstable phenomena that may occur during liquid flow.
[0017] The filter gap is designed in a unique zigzag shape, and the corner thereof is designed in a smooth arc shape, which reduces the resistance during liquid flow, thereby improving the efficiency of liquid flow. Meanwhile, the wave-preventing hole in the end face of the push plate can reduce the excessive fluctuation of the liquid in the sediment separation cavity, thereby maintaining the stable flow of the liquid, which is crucial for the smooth operation of the entire system.
[0018] In order to ensure the sealing of the connection part, prevent liquid leakage, the sealing ring is specially arranged at the connection part of the drain pipe and the drain pipe and the bin body. In addition, the mechanical sealing technology is used between the bearing device and the screw feeder and the bin body, and the precise sealing mode further ensures the safety and reliability of the system, and provides guarantee for the long-term stable operation of the sewage treatment equipment.
