Description

Technical Field

[0001] The utility model relates to the field of water treatment, in particular to a mud pump anti-blocking device. Background Art

[0002] The sewage treatment process often involves the treatment of sludge. The mud treatment system generally adopts the process of sludge pre-thickening tank → mud pump → thickening tank → plate and frame filter press → mud cake, that is, the sewage enters the sludge pre-thickening tank, and then the mud pump sends the mud discharged from the sludge pre-thickening tank to the thickening tank. After being treated in the thickening tank, the plate and frame filter press compresses it into mud cake to achieve the purpose of dehydration and volume reduction for subsequent transportation and treatment. Among them, mud pump is a popular concept of a broad pump, which mainly refers to a pump that can extract and transport non-clean water such as mud, sewage, slag slurry and other materials.

[0003] Sludge pre-thickening tanks are mostly horizontal flow type, and are equipped with a mud tank and a water inlet pipe. Sewage enters the sludge pre-thickening tank through the water inlet pipe. The mud tank is connected to multiple mud pumps through multiple mud inlet pipes. The oil and mud scraper trolley scrapes the mud at the bottom of the sludge pre-thickening tank into the mud tank, and then the mud is pumped into the thickening tank through the mud pump. In the area of ​​the mud tank close to the water inlet pipe, the mud concentration is low due to the impact of the water flow, so the mud concentration in the mud inlet pipe here is also low, and the mud pump connected to the mud inlet pipe will run smoothly; while in the area of ​​the mud tank far away from the water inlet pipe, the mud concentration is high, and the mud concentration in the mud inlet pipe here is also high, and the mud inlet pipe is often blocked. After opening the pipeline to dredge the mud inlet pipe, the mud pump encounters greater resistance due to the high mud concentration, which can also cause the mud pump to discharge mud poorly and slowly, and the mud accumulates at the water suction port of the mud pump, causing the water suction port of the mud pump to be blocked and the mud inlet pipe to be blocked again, and even causing damage to the mud pump, increasing maintenance costs.

[0026] The following will give a preferred embodiment of the present utility model in conjunction with the drawings and describe it in detail.

[0027] Figure 1 It is a schematic diagram of a mud pump anti-blocking device according to an embodiment of the present utility model. Please refer to Figure 1 , the embodiment of the present utility model provides a mud pump anti-blocking device, including a mud pump 1, a mud inlet pipe 2, a water flushing pipeline 4 and an air flushing pipeline 3. The mud inlet pipe 2 and the water flushing pipeline 4 can both be steel pipes. The mud pump 1 is arranged on the mud inlet pipe 2. It can be understood that the mud inlet pipe 2 is powered by the mud pump 1 to send the mud to the next process.

[0028] The water flushing pipeline 4 is connected to the mud inlet pipe 2. The water flushing pipeline 4 is located in the upstream direction of the mud pump 1, that is, along the direction of the mud inlet pipe 2. The water flushing pipeline 4 dilutes the mud in the mud inlet pipe 2 by using water flow. Further, the water flushing pipeline 4 includes a connected main water pipe 41 and a branch water pipe 42. The branch water pipe 42 is connected to the mud inlet pipe 2. Exemplarily, the diameter of the branch water pipe 42 is smaller than that of the mud inlet pipe 2. For example, the diameter of the mud inlet pipe 2 can be 150 mm, and the diameter of the branch water pipe 42 can be 20 mm. The main water pipe 41 is used to be connected to the water supply network. The water supply network can be, for example, the tap water network. The water pressure in the main water pipe 41 can be about 4 kilograms. A main water flushing valve 411 is provided on the main water pipe 41, and a second regulating valve 421 with adjustable opening degree is provided on the branch water pipe 42. The water pressure of the branch water pipe 42 can be adjusted by adjusting the opening degree of the second regulating valve 421.

[0029] The air flushing pipeline 3 is connected to the mud inlet pipe 2. The air flushing pipeline 3 is located in the upstream direction of the mud pump 1, that is, along the direction of the mud inlet pipe 2. The air flushing pipeline 3 dredges the mud inlet pipe 2 by using compressed air. Further, the air flushing pipeline 3 includes a connected main air pipe 31 and a branch air pipe 32. The branch air pipe 32 is connected to the mud inlet pipe 2. Exemplarily, the diameter of the branch air pipe 32 is smaller than that of the mud inlet pipe 2. For example, the diameter of the mud inlet pipe 2 can be 150 mm, and the diameter of the branch air pipe 32 can be 20 mm. The main air pipe 31 is used to be connected to the compressed air network. The pressure of the main air pipe 31 can be about 6 kilograms. A main air flushing valve 311 is provided on the main air pipe 31, and a first regulating valve 321 with adjustable opening degree is provided on the branch air pipe 32. The air pressure of the branch air pipe 32 can be adjusted by adjusting the opening degree of the first regulating valve 321.

[0030] It can be understood that a mud inlet valve 21 is provided on the mud inlet pipe 2. The mud inlet valve 21 is located at the inlet end of the mud pump 1, that is, the mud inlet valve 21 is close to or located at the suction port of the mud pump 1. And along the direction of the mud inlet pipe 2, the mud inlet valve 21 is located in the downstream direction of the air flushing pipeline 3 and in the downstream direction of the water flushing pipeline 4. When the mud inlet valve 21 is opened, the mud can enter the mud pump 1.

[0031] Preferably, a first valve 22 is provided on the mud inlet pipe 2, and the first valve 22 is located in the downstream direction of the mud pump 1, that is, along the direction of the mud inlet pipe 2, the first valve 22 is located in the downstream direction of the mud pump 1. A valve is provided in the downstream direction of the mud pump 1 to facilitate the control of mud flowing into the next process. Further, a second valve 23 is also provided on the mud inlet pipe 2. For example, the first valve 22 can be a manual switch valve, and the second valve 23 can be an electric switch valve. When the mud pump anti-blocking device is working, the first valve 22 remains in a normally open state, and the second valve 23 is opened and closed by remote control. When maintenance is required, the first valve 22 and the second valve 23 are both closed. The manual switch valve and the electric switch valve are provided at the same time to play a double insurance role. If the electric switch valve fails, the manual switch valve can continue to be used.

[0032] The valves mentioned in this embodiment can all be valves with reliable cutting function, such as ball valves.

[0033] Generally speaking, there are more than one mud inlet pipe 2. For example, the sludge pre-thickening tank is connected to the thickening tank through three mud inlet pipes 2. Accordingly, a mud pump 1 is provided on each mud inlet pipe 2. Each mud inlet pipe 2 can be connected to the water flushing pipeline 4 and the air flushing pipeline 3, or the water flushing pipeline 4 and the air flushing pipeline 3 can be connected only to the mud inlet pipe 2 at the location with higher mud concentration. Figure 1 That is, each mud inlet pipe 2 is connected to the water flushing pipeline 4 and the gas flushing pipeline 3, that is, three parallel water pipe branches 42 are connected to a water pipe main pipe 41, and the three water pipe branches 42 correspond to the three mud inlet pipes 2 one by one. Similarly, three parallel gas pipe branches 32 are connected to a gas pipe main pipe 31, and the three gas pipe branches 32 correspond to the three mud inlet pipes 2 one by one. The gas pipe branch 32 and the water pipe branch 42 can first intersect and then be connected to the mud inlet pipe 2. For example, the gas pipe branch 32 and the water pipe branch 42 intersect and enter the water-gas flushing pipeline 5, and the water-gas flushing pipeline 5 is then connected to the mud inlet pipe 2. The water-gas flushing pipeline 5 is provided with a third valve 51 for controlling opening and closing.

[0034] When feeding mud, the mud inlet valve 21, the first valve 22 and the second valve 23 are all kept open. When the mud feeding is blocked or the mud is viscous, open the main water flushing valve 411, the second regulating valve 421 and the third valve 51, and adjust the water pressure through the second regulating valve 421. Use the pressurized water flow to dilute the mud in the mud inlet pipe 2, so as to make the mud transportation smooth. At this time, the water flow flushes along the flow direction of the mud. The pressurized water flow can also backflush the mud inlet pipe. At this time, it is necessary to close the mud inlet valve 21, open the main water flushing valve 411, the second regulating valve 421 and the third valve 51. In this way, the water flow can flush against the flow direction of the mud. In this embodiment, the mud inlet pipe can be dredged and maintained regularly (the frequency can be kept at 1-2 times a week) with compressed air. Specifically, close the mud inlet valve 21, open the main air flushing valve 311, the first regulating valve 321 and the third valve 51, and make the compressed air flush against the flow direction of the mud to dredge and maintain the mud inlet pipe.

[0035] With the above configuration, the utility model is provided with a water flushing pipeline 4. When the mud is viscous, the water flushing pipeline 4 introduces the pressurized water flow into the mud inlet pipe 2, so as to dilute the mud in the mud inlet pipe 2 and the mud at the suction port of the mud pump 1, ensuring smooth mud transportation; the utility model is also provided with an air flushing pipeline 3. The air flushing pipeline 3 uses compressed air to conduct air flow flushing on the mud inlet pipe 2, so as to regularly dredge the mud inlet pipe 2. In summary, the mud pump anti-blocking device of the utility model can prevent the mud inlet pipe 2 and the mud pump 1 from being blocked, ensure smooth mud transportation, avoid damage to the mud pump 1 due to blockage of the suction port, increase the service life of the mud pump 1, and has the advantages of strong practicability and wide application.
