Description

Technical Field

[0001] This utility model relates to the field of construction wastewater transportation technology, and in particular to a drainage transportation device. Background Technology

[0002] During construction, groundwater deposition can affect the work, so drainage systems are needed to remove the groundwater. Since the groundwater contains impurities such as mud and gravel, forming wastewater, wastewater treatment equipment is required to treat it. In addition, in some areas with geothermal resources, the residual heat in the groundwater can also be recovered.

[0003] However, during use, it was found that the existing sewage treatment facilities have a relatively simple structure, making it inconvenient to clean the sediment in the sewage during transportation and to recover the waste heat from the sewage, resulting in poor practicality.

[0004] In view of the problems existing in the prior art, it is necessary to research and design a new type of drainage and transportation device to overcome the problems existing in the prior art. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a drainage transportation device that uses a sedimentation mechanism to transport sewage, causing particulate matter in the sewage to settle into the sedimentation mechanism. At the same time, a waste heat recovery mechanism recovers waste heat from the sewage, and a cleaning mechanism cleans the sediment in the sedimentation mechanism, thereby improving the practicality of the equipment.

[0006] The technical means adopted in this utility model are as follows:

[0007] A drainage transport device includes a sedimentation mechanism; it also includes a cleaning mechanism and a waste heat recovery mechanism, both of which are installed in the sedimentation mechanism;

[0008] Preferably, the sedimentation unit settles particulate matter in the wastewater, the cleaning unit cleans the sediment in the sedimentation unit, and the waste heat recovery unit recovers waste heat from the wastewater.

[0009] Preferably, wastewater is transported through a sedimentation mechanism, causing particulate matter in the wastewater to settle into the sedimentation mechanism. At the same time, waste heat is recovered from the wastewater through a waste heat recovery mechanism, and the sediment in the sedimentation mechanism is cleaned through a cleaning mechanism, thereby improving the practicality of the equipment.

[0010] Preferably, the sedimentation mechanism includes a sedimentation tank, an inlet valve, an overflow port, and a screen. The inlet valve is installed on the left side of the sedimentation tank, the overflow port is installed on the right side of the sedimentation tank, and the screen is installed in the overflow port. When the inlet valve is opened, sewage is discharged into the sedimentation tank. Through the cooperation of the sedimentation tank and the waste heat recovery mechanism, the particulate matter in the sewage settles to the bottom of the sedimentation tank. Then, the sewage in the sedimentation tank overflows into the overflow port, and the sewage in the overflow port is filtered by the screen before being discharged through the overflow port, thereby improving the practicality of the equipment.

[0011] Preferably, the cleaning mechanism includes two sets of slide rails, two sets of electric sliders, a support plate, a drain pipe, a hose, an electric control valve, and multiple pressure regulating mechanisms. The two sets of slide rails are respectively installed at the front and rear of the sedimentation tank. The two sets of electric sliders are slidably installed on the two sets of slide rails. The support plate is fixedly installed on the two sets of electric sliders. The drain pipe is fixedly installed on the support plate, and multiple suction ports are provided at the bottom of the drain pipe. One end of the hose is installed on the drain pipe, and the other end of the hose extends outside the sedimentation tank. The electric control valve is installed at the other end of the hose and is lower than the sedimentation tank. Multiple regulating mechanisms are installed on the drain pipe. By sliding the electric sliders on the slide rails, the position of the support plate is adjusted. At the same time, the electric control valve is opened, allowing the drain pipe to discharge the sediment at the bottom of the sedimentation tank into the hose. Then, the electric control valve discharges the sediment in the hose. When encountering stubborn sediment, the multiple regulating mechanisms work in conjunction with the drain pipe to clean it, thereby improving the practicality of the equipment.

[0012] Preferably, the regulating mechanism includes a pressure regulating cylinder, a piston, and an electric cylinder. The pressure regulating cylinder is installed on the sewage pipe, the piston is slidably installed in the pressure regulating cylinder, and the electric cylinder is fixedly installed on the pressure regulating cylinder, with one end of the electric cylinder connected to the piston. When encountering stubborn sediment, the electric control valve is closed, and the piston slides upward by the contraction of the electric cylinder, drawing sewage into the pressure regulating cylinder. Then, the sewage in the pressure regulating cylinder is quickly discharged by the extension of the electric cylinder, dispersing the stubborn sediment. The electric control valve is then opened to continue cleaning the sediment at the bottom of the sedimentation tank, thereby improving the practicality of the equipment.

[0013] Preferably, the waste heat recovery mechanism includes an inlet pipe, an outlet pipe, multiple sets of baffles, and multiple sets of heat exchange tubes. The inlet pipe is installed at the rear of the sedimentation tank, and the outlet pipe is installed at the front of the sedimentation tank. The multiple sets of baffles are all installed at an angle inside the sedimentation tank. The multiple sets of heat exchange tubes are respectively installed on the multiple sets of baffles, and one end of each set of heat exchange tubes is connected to the interior of the inlet pipe, while the other end of each set of heat exchange tubes is connected to the interior of the outlet pipe. The inlet pipe and the outlet pipe are connected to the drainage pipe. When the sewage flows inside the sedimentation tank, the multiple sets of baffles simultaneously block the sewage, reducing the water flow rate and causing the particulate matter in the sewage to settle. At the same time, the heat exchange liquid is discharged into the heat exchange tubes through the inlet pipe. The heat is conducted through the heat exchange tubes and baffles, transferring the heat from the sewage into the heat exchange liquid inside the heat exchange tubes. Finally, the heat exchange liquid in the multiple sets of heat exchange tubes is discharged through the outlet pipe, thereby improving the practicality of the equipment.

[0014] Preferably, guide plates are provided at both the front and rear of the sedimentation tank, and the two sets of guide plates are located above the two sets of slide rails respectively; the guide plates guide the sediment, reduce the sediment falling on the slide rails, and improve the smoothness of the electric slider.

[0015] Preferably, the sedimentation tank has an inverted trapezoidal structure; this facilitates the accumulation of sediment, thereby improving the practicality of the equipment.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This utility model provides a drainage transportation device that transports sewage through a sedimentation mechanism, causing particulate matter in the sewage to settle into the sedimentation mechanism. At the same time, a waste heat recovery mechanism recovers waste heat from the sewage, and a cleaning mechanism cleans the sediment in the sedimentation mechanism, thereby improving the practicality of the equipment.
