Description

Technical Field

[0001] The utility model relates to the technical field of wastewater pipelines, in particular to an industrial wastewater treatment and transportation pipeline. Background Art

[0002] Circuit board industrial wastewater mainly comes from various processes in the circuit board production process, such as drilling, etching, electroplating, cleaning and other links; these wastewaters contain a variety of harmful substances, mainly including heavy metals, organic pollutants, acidic and alkaline substances, and suspended solids.

[0003] In order to treat wastewater, it is necessary to transport the wastewater to the treatment pool through a conveying pipe. However, due to the equipment layout in the factory, most of the conveying pipes have curved sections. Due to the change in the direction of the pipe, the water flow speed and direction change at the curved section, causing the suspended matter carried therein to settle more easily and easily form a blockage. When clearing the blockage, it is necessary to stop the delivery of the wastewater and dismantle the entire section of the pipe. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model aims to provide an industrial wastewater treatment delivery pipeline which does not require stopping wastewater delivery and is convenient for cleaning blocked curved pipes.

[0005] The technical solution adopted by the utility model is as follows:

[0006] An industrial wastewater treatment delivery pipeline comprises a straight liquid inlet pipe, a straight liquid discharge pipe and a curved pipe, wherein both ends of the curved pipe are respectively connected to the straight liquid inlet pipe and the straight liquid discharge pipe, and further comprises a diverter pipe, wherein the side walls of the straight liquid inlet pipe and the straight liquid discharge pipe are provided with diverter holes, wherein both ends of the diverter pipe are respectively connected to the corresponding diverter holes, a first valve is detachably installed between the straight liquid inlet pipe and the curved pipe, and a second valve is detachably installed between the straight liquid discharge pipe and the curved pipe.

[0007] Working principle: wastewater enters through the straight inlet pipe and is discharged through the straight discharge pipe. Due to the change in flow rate, some suspended matter is deposited in the curved pipe. When cleaning the curved pipe, the first valve and the second valve can be closed, and the curved pipe can be disassembled to allow wastewater to flow from the diversion pipe to the straight discharge pipe.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] By providing a detachable bent pipe, when clearing a blockage, only the bent pipe needs to be disassembled, and there is no need to stop the transportation of wastewater, thereby ensuring the normal operation of the wastewater treatment pool.

[0010] As a preferred embodiment of the present utility model, a third valve is provided on the diverter pipe.

[0011] Beneficial effect: By setting the third valve, when there is no need to clear the blockage, the flow in the shunt pipe stops flowing, thus avoiding blockage of the shunt pipe.

[0012] As a preferred embodiment of the utility model, the openings of the two diversion holes are both facing upward, the diversion pipe includes two vertical parts and a transverse part, the two vertical parts are located above the corresponding diversion holes, the transverse part is located between the two vertical parts, and the third valve is arranged on the vertical part of the liquid inlet straight pipe.

[0013] Beneficial effect: By setting the diversion port opening upward and arranging the third valve on the vertical part of the liquid inlet straight pipe, under normal working conditions, the wastewater is blocked by the third valve, and the suspended matter in the wastewater is not easy to be deposited in the diversion pipe.

[0014] As a preferred embodiment of the present invention, a filter screen is arranged inside the curved pipe.

[0015] Beneficial effect: Since suspended matter is easily deposited in the curved pipe, a filter screen is set to filter the suspended matter, thereby reducing the processing load of the subsequent wastewater treatment system. The curved pipe is easy to disassemble and does not affect the operation of the wastewater treatment system, which can increase the cleaning frequency of the curved pipe.

[0016] As a preferred embodiment of the utility model, the filter screen is arranged at one end of the curved pipe close to the water outlet.

[0017] Beneficial effect: By setting the filter screen on the side away from the first valve, it is avoided that suspended matter is deposited between the first valve and the filter screen, which causes a large amount of impurities to adhere to the first valve, affecting normal opening and closing and increasing the difficulty of cleaning.

[0018] As a preferred embodiment of the utility model, the first valve and the second valve are both butterfly valves, and the pipe openings of the straight liquid inlet pipe, the straight liquid discharge pipe, and the curved pipe are all connected to the butterfly valve bolts through connecting flanges.

[0019] Beneficial effect: It is connected with the bent pipe bolts through the butterfly valve, which is convenient for disassembly and installation when clearing the blockage.

[0020] As a preferred embodiment of the present utility model, a pressure sensor is arranged in the liquid inlet straight pipe.

[0021] Beneficial effect: By setting a pressure sensor, the pressure in the pipeline is measured. When the pressure increases, it means that there is a blockage inside the pipeline. By setting a preset value, cleaning work is carried out when it exceeds the preset value. BRIEF DESCRIPTION OF THE DRAWINGS
