Description

Technical Field

[0001] This utility model relates to the field of sludge sedimentation tank technology, specifically to a sludge sedimentation tank that is easy to clean. Background Technology

[0002] Sludge sedimentation tanks are key equipment in wastewater treatment systems, mainly used to remove suspended solids and sludge from wastewater through gravity settling, thereby purifying the water quality.

[0003] For example, announcement number CN212491920U (titled "A Sludge Settling Tank for Easy Cleaning") includes a sludge settling tank with an opening at the top. A sludge collection box is detachably connected to the bottom of the sludge settling tank. A tilting mechanism is provided on the bottom wall of the sludge settling tank. The tilting mechanism includes a tilting plate, hooks, reinforcing ropes, collars, a motor, a first rotating shaft, and a fixed ring. The tilting plate is hinged at the connection between the sludge settling tank and the sludge collection box. One end of each of the two sets of reinforcing ropes is fixed to both ends of the tilting plate along its length. The other ends of the two sets of hooks are respectively located on the two sets of reinforcing ropes. The two sets of collars are respectively installed on both sides of the top of the sludge settling tank, and the hooks and collars are respectively hooked together. The motor is fixedly connected to... The first rotating shaft is coaxially connected to the output end of the motor and is located inside the sludge collection box near the tilting plate. The fixing ring is welded to the side of the tilting plate away from the motor. The end of the first rotating shaft is sleeved with the fixing ring. When the sludge settles in the sedimentation tank, the operator uses a water pump to remove water from the sedimentation tank. At this time, the hook is removed from the sleeve, and the motor is driven to rotate. The motor drives the first rotating shaft to rotate, which in turn drives the tilting plate to rotate. When the tilting plate tilts and tends to be vertical, the sludge on the tilting plate slides down into the sludge collection box under the action of gravity, reducing the accumulation of sludge at the bottom of the sedimentation tank and affecting the sedimentation effect. Finally, the sludge in the sludge collection box is emptied, which conveniently and quickly achieves the requirements for sludge sedimentation and cleaning.

[0004] The aforementioned sludge sedimentation tank facilitates sludge removal and cleaning through its tilting plate structure. However, the poor sealing of the sludge sedimentation tank during bottom cleaning and sewage discharge leads to poor sedimentation and separation efficiency. Therefore, we provide a sludge sedimentation tank that is easy to clean. Utility Model Content

[0005] The purpose of this utility model is to provide a sludge sedimentation tank that is easy to clean, in order to solve the problem mentioned in the background art that the existing sludge sedimentation tanks have a set tipping plate structure to facilitate the dumping and cleaning of sludge, but the sludge sedimentation tank has poor sealing when cleaning and discharging sludge from the bottom, resulting in poor sedimentation and separation effect of the sludge sedimentation tank.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sludge sedimentation tank that is easy to clean, comprising a sedimentation frame, a drying frame welded to one side of the outer wall of the sedimentation frame, an electric heating plate fixed inside the drying frame by nail-free adhesive, a multi-stage hydraulic cylinder on one side of the sedimentation frame, and an electric push rod on one side of the multi-stage hydraulic cylinder.

[0007] Also includes:

[0008] An inner groove is provided on one side of the inner wall of the sedimentation frame, and a sludge support plate is provided inside the inner groove and the sedimentation frame. A traction rod is provided in the groove of the inner groove, and the two ends of the traction rod are welded to one end of the sludge support plate and one end of the piston rod of the multi-stage hydraulic cylinder, respectively.

[0010] A track frame is positioned above the sedimentation frame, and a threaded screw is provided inside the track frame. A screw slider is movably mounted on the threaded screw, and the top of the linkage rod is welded to the bottom of the screw slider.

[0011] A water pump is fixedly mounted on the seat plate at the top of the electric push rod piston rod by screws, and a water pump pipe and a water drain pipe are respectively sealed and connected at the water inlet and water outlet of the water pump. The water pump pipe is located inside the sedimentation frame.

[0012] Preferably, a power supply box is provided on one outer wall of the drying frame, and a power supply switch is provided below the power supply box. The output and input terminals of the power supply switch are electrically connected to the heating plate and the power supply box respectively through connecting wires.

[0013] Preferably, one end of the sedimentation frame is provided with a water inlet, and a sewage guide frame is welded to one side of the water inlet, and the sewage guide frame is connected to the water inlet.

[0017] Preferably, the end face size of the sludge tray is equal to the sum of the groove size of the sedimentation frame and the inner groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention uses an electric push rod to drive a water pump to raise and lower, adjusting the position of the pumping pipe to the height of the upper layer of clear water. The pump then draws the settled upper layer of clear water from inside the sedimentation frame. Next, a multi-stage hydraulic cylinder pulls a traction rod to lift the sludge tray inside the sedimentation frame, allowing the tray to carry the settled sludge to the height of the edge groove. A servo motor then drives a threaded screw to rotate, guiding the screw slider along the track frame and displacing the scraper blade. This scrapes the settled sludge from the tray and pushes it into the drying frame, facilitating cleaning of the sludge sedimentation tank. This overcomes the problem of poor sealing and sedimentation separation in existing sludge sedimentation tanks, which use a tilting plate structure for easy sludge removal but suffer from poor sealing during bottom cleaning and discharge.
