Abstract
Description
Technical Field
[0001] This utility model relates to the field of sludge conveying pipe blockage detection and unblocking technology, specifically, to a self-inspection and unblocking system for sludge conveying pipelines. Background Technology
[0002] The fracturing flowback fluid in the storage tank is pumped into a high-efficiency inclined plate desander. An additive (demulsifier) is added to the inlet cyclone coil of the device. Through efficient oxidation and chemical action, demulsification and gelation are achieved, disrupting the stability of pollutants in the water. Strong oxidation removes blackening, deodorization, sterilization, and heavy metal ions and other impurities. The wastewater then flows by gravity into the effluent tank and is pumped to a coagulation oxidation unit. PAC and PAM are added to the inlet cyclone coil of this unit, further separating colloids and suspended solids from the water. The pre-purified water flows by gravity into the clear water tank, where a bactericide is added. After sterilization, the treated water is pumped into the clear water pool.
[0003] The high-efficiency inclined plate sludge remover scrapes out floating oil sludge and bottom-deposited sludge from the coagulation oxidation unit. This sludge is then transported to a sludge tank via gravity or a sludge pump through a pipeline. The sludge is then pumped into a filter press for concentration and volume reduction. The effluent is returned to the effluent tank for further chemical dosing and recycling. When the sludge concentration in the influent increases, the sludge transported in the pipeline is highly susceptible to clogging, especially when the pipeline has multiple bends and reversals, significantly increasing the probability of blockage. Once the pipeline is blocked, locating and clearing the blockage requires considerable time and manpower. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0024] Example 1:
[0025] Reference Figure 1 As shown, this embodiment provides a self-inspection and unblocking system for a sludge conveying pipeline. The conveying pipeline 1 includes several straight pipes 101 connected in sequence. Adjacent straight pipes 101 are connected to each other by elbows 102, thus maintaining a certain angle between the straight pipes 101, mostly 90°. The self-inspection and unblocking system for the conveying pipeline 1 mainly includes a processor 2, a pressure sensor 3, and a water pump 4. Each of the straight pipes 101 is provided with an installation section 103, and the installation section 103 is provided with a pressure sensor 3. The pressure sensor 3 is used to detect the pressure in the installation section 103. The pressure sensor 3 detects the pressure in the installation section 103 in real time and feeds the detected data back to the processor 2. When the pressure in one or more installation sections 103 increases, the straight pipe 101 where the blockage point is located can be quickly determined, which facilitates the subsequent unblocking and treatment of the blockage point.
[0026] More specifically, such as Figure 1As shown, the output end of water pump 4 is connected to installation section 103 via drain pipe 401; both pressure sensor 3 and water pump 4 are electrically connected to processor 2. Starting from the input end of the delivery pipe, when the Nth straight pipe 101 (N>0 and N=the number of straight pipes 101) or the elbow 102 connecting the straight pipe 101 to the next straight pipe 101 becomes blocked, the pressure from the input end of the delivery pipe to the Nth pressure sensor 3 will increase. Consequently, the first N pressure sensors 3 will detect this and provide feedback to processor 2. Then, processor 2 controls the start of water pump 4 to pump high-pressure water into the Nth installation section 103. After running for 20-40 seconds, operations are performed depending on the situation:
[0027] Once the values detected by the N pressure sensors 3 decrease and gradually return to normal, the water pump 4 will be shut down, thus stopping the pumping of high-pressure water.
[0028] More specifically, such as Figure 1 As shown, it also includes an air pump 5, the output end of which is connected to the mounting section 103 via an exhaust pipe 501; the air pump 5 is electrically connected to the processor 2. When the values detected by the current N pressure sensors 3 remain unchanged or increase, the processor 2 controls the air pump 5 to start, pumping high-pressure gas into the Nth mounting section 103. The air pump 5 works in conjunction with the water pump 4 to clear the blockage. The air pump 5 and water pump 4 are turned off once the pressure values detected by the current N pressure sensors 3 decrease or even return to normal.
[0029] Example 2:
[0030] Based on Example 1, such as Figure 2 As shown, the installation section 103 is connected to a dual-fluid nozzle 6, and the drain pipe 401 and the exhaust pipe 501 are both connected to the dual-fluid nozzle 6. Under the action of the dual-fluid nozzle 6, the high-pressure gas and high-pressure water form a high-pressure mist spray, which washes away the sludge accumulated in the installation section 103, and also serves as a high-pressure unblocking function for the blockage between the installation section 103 and the next installation section 103.
[0031] More specifically, such as Figure 1 and Figure 2 As shown, there is one and only one water pump 4, and several installation sections 103 are all connected to the drain pipe 401 through drain branch pipes 402. At the same time, a first solenoid valve 403 is installed on the drain branch pipe 402. The first solenoid valve 403 is electrically connected to the processor 2. Thus, when high-pressure water is pumped into a certain installation section 103, the processor 2 controls the first solenoid valve 403 of the drain branch pipe 402 connected to that installation section 103 to open, and closes the first solenoid valves 403 on the drain branch pipes 402 of the other installation sections 103, so that high-pressure water can be pumped into the designated installation section 103.
[0032] More specifically, such as Figure 1 and Figure 2 As shown, there is one and only one air pump 5, and several installation sections 103 are all connected to the exhaust pipe 501 through exhaust branch pipes 502. Meanwhile, a second solenoid valve 503 is installed on the exhaust branch pipe 502, and the second solenoid valve 503 is electrically connected to the processor 2. Therefore, when high-pressure gas is pumped into a certain installation section 103, the processor 2 controls the second solenoid valve 503 of the exhaust branch pipe 502 connected to that installation section 103 to open, while closing the second solenoid valves 503 on the exhaust branch pipes 502 of the other installation sections 103, thus enabling the pumping of high-pressure gas to the designated installation section 103.
[0033] In summary, this system quickly identifies the location of blockages in the delivery pipeline 1 by feeding back values from several pressure sensors 3 to the processor 2; and resolves the blockage quickly and effectively by pumping in water or a combination of air and water. Simultaneously, the gas and water pumped into the pipeline increase the fluidity of the sludge, further preventing subsequent blockages. The processor 3 automatically determines the location of the blockage and controls the unblocking operation, reducing the workload and usage intensity for maintenance personnel.
[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
