Description

Technical Field

[0001] This utility model relates to the technical field of limestone slurry conveying equipment, and in particular to a limestone slurry conveying pipe anti-blocking backflushing device. Background Technology

[0002] Limestone slurry, as a highly efficient chemical treatment medium, is effective in industrial wastewater treatment, especially in the treatment of acidic and heavy metal wastewater. Its efficient chemical treatment capabilities can effectively neutralize acidic substances in acidic wastewater and react chemically with heavy metal ions in the wastewater to form insoluble precipitates, thereby achieving effective removal of heavy metal ions.

[0003] In the specific operation of wastewater treatment, limestone is first ground into powder and mixed with water in a certain proportion to prepare a limestone slurry of a specific concentration. Then, the slurry is pumped into the wastewater treatment tank to ensure sufficient contact and chemical reaction with the wastewater. However, during transportation, the limestone slurry contains a certain amount of undissolved solid particles, which easily deposit on the inner wall of the pipes. Simultaneously, the high viscosity of the limestone slurry exacerbates particle accumulation and blockage within the pipes. Once the transport pipes become blocked, it not only affects the normal transport of the limestone slurry, causing interruptions in wastewater treatment, but also seriously impacts the normal operation of the entire wastewater treatment system. To ensure the smooth operation of wastewater treatment, staff need to regularly clean the transport pipes, which consumes a significant amount of time and manpower and reduces wastewater treatment efficiency.

[0004] Therefore, those skilled in the art are dedicated to developing a backflushing device to prevent clogging of limestone slurry conveying pipes, thereby reducing clogging and improving wastewater treatment efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a backflushing device for preventing blockage of limestone slurry conveying pipes, thereby reducing blockage of limestone slurry conveying pipes and improving sewage treatment efficiency.

The output end of the filter anti-clogging component is connected to an intermediate pipe, and the intermediate pipe is connected to a high-level output pipe and a low-level output pipe. A backwashing assembly, which is connected to the intermediate pipe.

[0007] The beneficial effects of adopting the above scheme are: by forming an anti-clogging and backflushing system through the conveying pump assembly, the filter anti-clogging assembly and the backflushing assembly, it can not only reduce the impact of solid particles during the conveying process to prevent pipeline blockage, but also effectively backflushing and cleaning when blockage occurs, thereby improving the reliability and continuous operation stability of the limestone slurry conveying system.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the filter anti-clogging assembly includes a rotating inner cylinder, the output end of the delivery pump assembly is located inside the rotating inner cylinder, the rotating inner cylinder is installed inside the rotating outer cylinder through a first rolling support assembly, the rotating outer cylinder is installed inside the fixed cylinder through a second rolling support assembly, and the lowest point of the fixed cylinder is connected to the intermediate pipe; The rotating inner cylinder has a first filter hole, the rotating outer cylinder has a second filter hole, and the rotating inner cylinder and the rotating outer cylinder are connected by a reversing assembly, which drives the rotating inner cylinder and the rotating outer cylinder to rotate in opposite directions.

[0010] The beneficial effects of adopting the above-mentioned further scheme are as follows: During the process of the reverse drive assembly driving the inner and outer cylinders to rotate in opposite directions, the conveying pump assembly conveys the limestone slurry to the inner cylinder for the first filtration. Large particles of impurities remain in the inner cylinder, while the slurry and small particles of impurities flow between the inner and outer cylinders. The inner and outer cylinders, which rotate in opposite directions, further grind the small particles of impurities before they flow into the fixed cylinder and are then conveyed to the intermediate pipe. Multi-stage filtration reduces the impact of impurities, and the filtered impurities are further ground into fine particles, reducing pipe blockage.

[0011] Furthermore, the diameter of the first filter hole is larger than the diameter of the second filter hole, and grinding balls are also provided inside the rotating inner cylinder.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the first filter hole is used to filter large particulate impurities, and the grinding balls grind the large particulate impurities during the rotation of the inner cylinder and then enter between the inner cylinder and the outer cylinder, reducing the blockage of the conveying pipeline by solid particles.

[0013] Furthermore, the outer wall of the rotating inner cylinder also has a first convex grinding block, and the outer wall of the rotating outer cylinder is provided with a second convex grinding block.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the inner cylinder and the outer cylinder rotate in opposite directions, thereby driving the first convex grinding block and the second convex grinding block to rotate in opposite directions, which is conducive to further grinding small particle impurities between the inner cylinder and the outer cylinder, and reducing solid particles clogging the conveying pipeline.

[0015] Furthermore, the reversing assembly includes a rotating shaft, a rotating sleeve, and a planetary gear assembly. The rotating shaft is connected to the bottom of the rotating inner cylinder and extends out of the fixed cylinder. The rotating sleeve is connected to the bottom of the rotating outer cylinder and extends out of the fixed cylinder.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the planetary gear assembly drives the inner and outer cylinders to rotate in opposite directions, thereby improving the filtration and grinding efficiency of the inner and outer cylinders.

[0017] Furthermore, the central gear of the planetary gear assembly is also connected to a drive shaft, and the drive shaft is connected to a power component. The rotation of the power component drives the inner rotating cylinder and the outer rotating cylinder to rotate in opposite directions.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the planetary gear assembly is equipped with a power component to provide continuous and stable driving power, ensuring that the inner and outer rotating cylinders rotate smoothly in opposite directions.

[0019] Furthermore, the backwashing assembly includes a flushing water pipe and a high-pressure gas pipe, both of which are connected to the intermediate pipe.

[0020] The beneficial effects of adopting the above-mentioned further solution are: by flushing the water pipe and the high-pressure gas pipe, dual cleaning of liquid and gas can be achieved, removing impurities in the pipe and improving the backflushing effect.

[0021] Furthermore, a flow sensor is installed on the intermediate tube, and the flow sensor is electrically connected to the control component.

[0023] Furthermore, a liquid level sensor is also installed inside the slurry storage tank.

Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figure 1 , Figure 2 As shown, a limestone slurry conveying pipe anti-clogging backflushing device includes... The pump assembly 1 is connected to the slurry storage tank 2 at its input end. The slurry storage tank 2 is also equipped with a liquid level sensor. The liquid level sensor can monitor the slurry level in the slurry storage tank 2 in real time. When the liquid level is lower than the preset threshold, it can send a signal to remind the operator to replenish the slurry in time, so as to avoid the pump assembly 1 running dry or the conveying interruption due to insufficient slurry, and ensure the continuous operation of the entire conveying system. The filter anti-clogging component 3 is connected to the output end of the delivery pump component 1. The output end of the filter anti-clogging component 3 is connected to the intermediate pipe 4. A flow sensor is installed on the intermediate pipe 4. The flow sensor is electrically connected to the control component (not shown in the figure). The flow sensor can monitor the flow rate change of the slurry in the intermediate pipe 4 in real time. When the flow rate is abnormal, it will transmit the signal to the control component. The control component can determine that the pipeline may be blocked, and thus provide a basis for the subsequent start of the backwash component 7. The intermediate pipe 4 is connected to the high-level output pipe 5 and the low-level output pipe 6 to meet the slurry delivery requirements at different height positions. Backwash assembly 7 is connected to intermediate pipe 4 and is used to backwash and clean the pipeline when it is blocked or tends to be blocked.

[0032] like Figure 2 In some embodiments, the filter anti-clogging component 3 includes a rotating inner cylinder 8, and a grinding ball 15 is also provided inside the rotating inner cylinder 8. When the rotating inner cylinder 8 rotates, the grinding ball 15 moves with the rotating inner cylinder 8 and impacts and grinds large particles of impurities entering the rotating inner cylinder 8, breaking the large particles of impurities into smaller particles so that they can pass through the filter holes later. The output end of the delivery pump component 1 is located inside the rotating inner cylinder 8 so that the slurry delivered by the delivery pump component 1 can directly enter the rotating inner cylinder 8 for preliminary treatment. The rotating inner cylinder 8 is installed inside the rotating outer cylinder 10 through the first rolling support component 9. The rotating outer cylinder 10 is installed inside the fixed cylinder 12 through the second rolling support component 11. The fixed cylinder 12 is installed on the frame and its lowest point is connected to the intermediate pipe 4. The slurry after filtration and grinding can flow into the intermediate pipe 4 from the lowest point of the fixed cylinder 12 under the action of gravity and the delivery pump component 1.

[0033] In a specific embodiment, both the first rolling support assembly 9 and the second rolling support assembly 11 include a fixed seat, on which a rolling rubber wheel is mounted, and the outer edge of the rolling rubber wheel abuts against the rotating inner cylinder 8 or the rotating outer cylinder 10.

[0034] The rotating inner cylinder 8 has a first filter hole 13, and the rotating outer cylinder 10 has a second filter hole 14. The diameter of the first filter hole 13 is larger than the diameter of the second filter hole 14, so that the slurry first passes through the first filter hole 13 for coarse filtration, retaining larger particulate impurities inside the rotating inner cylinder 8. The slurry and smaller particulate impurities then pass through the first filter hole 13 into the space between the rotating inner cylinder 8 and the rotating outer cylinder 10, and then pass through the second filter hole 14 for fine filtration, further retaining smaller particulate impurities. The outer wall of the rotating inner cylinder 8 also has a first convex abrasive block 16, and the outer wall of the rotating outer cylinder 10 is provided with a second convex abrasive block 17. The rotating inner cylinder 8 and the rotating outer cylinder 10 are connected by a reversing assembly, which drives the rotating inner cylinder 8 and the rotating outer cylinder 10 to rotate in opposite directions. Specifically, the reverse component drives the inner cylinder 8 and the outer cylinder 10 to rotate in opposite directions. When the inner cylinder 8 and the outer cylinder 10 rotate in opposite directions, the first convex grinding block 16 and the second convex grinding block 17 will generate relative motion, further grinding the small particulate impurities that enter between them and breaking them into finer particles to reduce the risk of blockage to subsequent pipelines.

[0035] In this embodiment, the reversing assembly includes a rotating shaft 18, a rotating sleeve 19, and a planetary gear assembly 20. The rotating shaft 18 is connected to the bottom of the inner rotating cylinder 8 and extends out of the fixed cylinder 12. The rotating sleeve 19 is connected to the bottom of the outer rotating cylinder 10 and extends out of the fixed cylinder 12. The rotating shaft 18 is located inside the rotating sleeve 19. This nested structure allows the rotating shaft 18 and the rotating sleeve 19 to rotate independently without interfering with each other. The rotating shaft 18 is connected to the central gear of the planetary gear assembly 20, and the rotating sleeve 19 is connected to the outer gear ring of the planetary gear assembly 20. When the planetary gear assembly 20 is working, the central gear and the outer gear ring will rotate in opposite directions, thereby driving the rotating shaft 18 and the rotating sleeve 19 to rotate in opposite directions, ultimately achieving the reverse rotation of the inner rotating cylinder 8 and the outer rotating cylinder 10.

[0036] The central gear of the planetary gear assembly 20 is also connected to a drive shaft, which in turn is connected to a power assembly 21. The rotation of the power assembly 21 causes the inner rotating cylinder 8 and the outer rotating cylinder 10 to rotate in opposite directions. Specifically, the power assembly 21 can be an asynchronous motor. When the power assembly 21 is working, it drives the drive shaft to rotate, which in turn drives the central gear of the planetary gear assembly 20 to rotate. Under the transmission action of the planetary gear assembly 20, the central gear and the outer gear ring rotate in opposite directions, thereby causing the inner rotating cylinder 8 and the outer rotating cylinder 10 to rotate in opposite directions, providing continuous and stable power for the rotation of the inner rotating cylinder 8 and the outer rotating cylinder 10.

[0037] In a specific embodiment, the backwashing assembly 7 includes a flushing water pipe 22 and a high-pressure gas pipe 23, both of which are connected to an intermediate pipe 4. When the flow sensor detects an abnormal flow rate in the intermediate pipe 4 and determines that the pipe may be blocked, the valves of the flushing water pipe 22 and the high-pressure gas pipe 23 can be opened by the control assembly. High-pressure water is introduced into the intermediate pipe 4 through the flushing water pipe 22 to flush away the impurities adhering to the inner wall of the pipe, and high-pressure gas is introduced into the intermediate pipe 4 through the high-pressure gas pipe 23 to break up the blockage in the pipe using the impact force of the gas. At the same time, the high-pressure gas can also blow out the accumulated water and impurities in the pipe. Through the synergistic effect of water flushing and air flushing, the blockage in the pipe is effectively removed, and the pipe is restored to unobstructed flow. Meanwhile, after the delivery pump assembly 1 stops working, the high-pressure gas backwash filter anti-clogging assembly 3 can also backwash the first filter hole 13 on the rotating inner cylinder 8 and the second filter hole 14 on the rotating outer cylinder 10 to reduce the clogging of the filter holes.
