Description

Technical Field

[0001] The utility model relates to an automatic sewage cleaning device in an oil pipe and rod cleaning box, belonging to the technical field of cleaning boxes by flushing. Background Technique

[0002] At present, the cleaning of oil pipes and rods adopts a closed cleaning method. A certain amount of clean water is stored in the box, and heating coils are installed at the bottom. An external burner heats the coils to heat the clean water. The sludge generated after the oil pipes are soaked and rinsed in hot water will remain inside the cleaning box and settle to the bottom of the box. After long-term accumulation of sludge, it will occupy a large space inside the box, resulting in a reduction in the water storage capacity in the box. At the same time, the sludge will cover the heating coils at the bottom of the box, resulting in the inability to raise the temperature of the cleaning water to the required temperature for cleaning, increasing energy consumption and seriously affecting the cleaning effect. Therefore, production must be stopped regularly, and workers need to enter the box to clean the sewage manually. However, this not only has a large labor intensity and very low efficiency, but also the operation inside the box belongs to high-risk operation in a confined space.

[0003] In the existing technology for cleaning sludge at the bottom of an oil pipe and rod cleaning box, for example, the Chinese utility model patent with the authorization publication number CN218610816U and the authorization publication date of March 14, 2023, discloses an oil pipe cleaning box convenient for cleaning floating oil. A sewage discharge plate inclined downward is arranged at the bottom inside the main box, inclined guide plates are arranged on both sides of the sewage discharge plate, a sludge flushing assembly is arranged at the upper end of the sewage discharge plate, a sub-box is arranged on one side of the main box close to the lower end of the sewage discharge plate, a sewage discharge port connected to the sub-box is arranged at the lower side of the main box, a gate is arranged at the sewage discharge port, and the sewage after flushing the bottom surface automatically flows to the sewage discharge port under the guidance of the sewage discharge plate and the guide plate and flows into the sub-box.

[0004] However, the lowest part of the sewage discharge plate is directly connected to the sewage discharge port. The width of the sewage discharge port needs to be the same as the width of the connected sewage discharge plate, so the opening shape of the sewage discharge port is strip-shaped, which limits the external devices of the sewage discharge port and is not convenient for connecting external pipelines. The sewage discharge is not flexible enough. The sub-box can only be arranged closely beside the main box to collect sewage, and the sewage discharge port is at the bottom of the sub-box. It is impossible to store more sewage in the sub-box, otherwise the sewage will flow back into the main box. Therefore, the sewage in the sub-box also needs to be discharged in time, resulting in very inconvenient use. In addition, two inclined guide plates are used in the main box to guide the sewage to the sewage discharge port. The guide plates occupy the space above the sewage discharge plate, making the structure inside the box complex. Moreover, sludge will accumulate on the top surface of the guide plates and in the grooves between the guide plates and the side walls of the main box, and this part of the sludge cannot be cleaned. Therefore, the cleaning effect of the entire cleaning box is relatively poor. Content of the Utility Model

[0005] The purpose of the present utility model is to provide an automatic sewage cleaning device inside an oil pipe and rod cleaning tank, so as to solve the problems that in the automatic sewage cleaning device of the oil pipe and rod cleaning tank, the setting of two guide plates for guiding sewage makes the structure inside the tank complex, and the sludge deposited at the corresponding positions of the guide plates cannot be automatically cleaned, resulting in poor cleaning effect.

The structure is simple and does not occupy too much space inside the cleaning box, so that the structure inside the box is simple, and there is no position where the sludge cannot be automatically cleaned, and the cleaning effect is good.

[0025] An embodiment of the automatic sewage cleaning device in the tubing and rod cleaning box of the present utility model:

[0026] Such as Figure 1 , Figure 2 and Figure 4 shown, the automatic sewage cleaning device in the tubing and rod cleaning box includes a cleaning box body 1. The cleaning box body 1 includes a left side plate 1.2, a right side plate 1.3, a bottom plate 1.4, a front side plate 1.5, and a rear side plate 1.6. Such as Figure 1As shown, a sewage discharge plate 1.1 is provided on the bottom plate 1.5 inside the cleaning box body 1. The sewage discharge plate 1.1 includes an inclined plate section 1.11 and a vertical plate section 1.12 connected to the inclined plate section 1.11. Among them, the top surface of the inclined plate section 1.11 forms a sewage discharge inclined surface, and above the sewage discharge inclined surface, there is a flushing pipe for flushing the sludge on the sewage discharge inclined surface, that is, there is a flushing pipe above the top surface of the inclined plate section 1.11. In this embodiment, there are two sewage discharge plates 1.1, and the structures and sizes of the two sewage discharge plates 1.1 are the same, that is, there are two sewage discharge inclined surfaces and they are symmetrically arranged. The highest points of the sewage discharge plates 1.1 are connected, so that the two sewage discharge inclined surfaces form an inverted V-shaped structure, and the above-mentioned flushing pipes are arranged above each sewage discharge inclined surface, so that the bottom plate 1.5 inside the cleaning box body 1 can be divided into two parts and cleaned separately, enhancing the cleaning effect.

[0027] As Figure 1 and Figure 2 shown, the flushing pipes above each sewage discharge inclined surface each include a primary flushing pipe 9 arranged corresponding to the highest position of the top surface of the inclined plate section 1.11, a final-stage flushing pipe 6 arranged corresponding to the lowest position of the top surface of the inclined plate section 1.11, and at least one intermediate flushing pipe located between the primary flushing pipe 9 and the final-stage flushing pipe 6. In this embodiment, there are two intermediate flushing pipes, namely a secondary flushing pipe 8 and a tertiary flushing pipe 7, and the secondary flushing pipe 8 is adjacent to the primary flushing pipe 9, and the tertiary flushing pipe 7 is adjacent to the final-stage flushing pipe 6. Thus, four flushing pipes are respectively arranged above the two sewage discharge inclined surfaces, improving the flushing effect on the sewage discharge inclined surfaces.

[0028] The above-mentioned water outlet structures are provided on each flushing pipe, and the water outlet structures are arranged at intervals along the extending direction of the flushing pipe. In this embodiment, the water outlet structure is set as a nozzle, each nozzle corresponds to the corresponding flushing pipe, the nozzle on the primary flushing pipe 9 is a primary nozzle 5, the nozzle on the secondary flushing pipe 8 is a secondary nozzle 4, the nozzle on the tertiary flushing pipe 7 is a tertiary nozzle 3, the nozzle on the final-stage flushing pipe 6 is a final-stage nozzle 2, and there are five nozzles at each level, and the flushing ranges of all nozzles can cover the entire sewage discharge inclined surface to ensure the flushing effect on the sewage discharge inclined surface.

[0029] As Figure 2 shown, control valves for independently controlling whether the corresponding flushing pipes are filled with water are provided on the primary flushing pipe 9, secondary flushing pipe 8, tertiary flushing pipe 7 and final-stage flushing pipe 6. In this embodiment, the control valves are all electrically controlled valves, namely a primary valve 13, a secondary valve 12, a tertiary valve 11 and a quaternary valve 10, and the primary flushing pipe 9, secondary flushing pipe 8, tertiary flushing pipe 7 and final-stage flushing pipe 6 are respectively connected to a confluence pipe 22 through the primary valve 13, secondary valve 12, tertiary valve 11 and quaternary valve 10. Thus, only one water source communicated with the confluence pipe 22 needs to be provided, and the structure is simple and convenient for arrangement.

[0030] As shown in Figure 1 , Figure 2 and Figure 4 shown, a sewage collection tank 14 is provided between the lowest points of the two sewage discharge inclined planes and the corresponding side walls of the box body. The bottom wall of the sewage collection tank 14 is inclined, and the inclination direction is perpendicular to the inclination direction of the sewage discharge inclined plane. Specifically, an inclined sewage collecting plate 20 is further provided at the inner bottom of the cleaning box body 1. There are two sewage collecting plates 20, which are respectively located on the left and right sides inside the cleaning box body 1. The left sewage collecting plate 20 is fixedly connected to the vertical plate section 1.12 of the corresponding sewage discharge plate 1.1, the left side plate 1.2, the bottom plate 1.4 and the rear side plate 1.6 of the box body. The right sewage collecting plate 20 is fixedly connected to the vertical plate section 1.12 of the corresponding sewage discharge plate 1.1, the right side plate 1.3, the bottom plate 1.4 and the rear side plate 1.6 of the box body. And the two sewage collecting plates 20 respectively form two sewage collection tanks 14 together with the corresponding fixedly connected side plates and the vertical plate sections 1.12 of the corresponding sewage discharge plates 1.1. The top surfaces of the two sewage collecting plates 20 respectively constitute the bottom walls of the corresponding sewage collection tanks 14. Sewage discharge ports 15 are provided at the lowest points of the bottom walls of the sewage collection tanks 14, and the sewage discharge ports 15 are all located on the front side plate 1.5. During use, after the sewage generated by flushing the sewage discharge inclined plane flows down from the sewage discharge inclined plane, it will be collected in the adjacent sewage collection tank 14, and under the action of the inclined bottom wall and the gravity of the sewage itself, it will flow in the direction of the sewage discharge port 15.

[0031] As shown in Figure 2 shown, sewage discharge pipes 21 for discharging sewage into the collection box 23 are respectively connected to the two sewage discharge ports 15. Each sewage discharge pipe 21 is provided with a sewage discharge valve 16 for independently controlling sewage discharge or not. During use, the discharge of the sewage discharge pipe 21 can be controlled separately. In this embodiment, the sewage discharge valve is an electric control valve. A sewage collecting pipe 18 is connected to the intersection of the two sewage discharge pipes 21, so that the sewage discharged from the two sewage discharge ports 15 can be collected into the sewage collecting pipe 18 and then uniformly treated.

[0032] As shown in Figure 2 and Figure 3 shown, the automatic sewage cleaning device in the tubing rod cleaning box further includes a collection box 23 provided below the cleaning box body to collect the sewage collected in the sewage collecting pipe 18, so as to facilitate centralized treatment of the sewage. A steel cover plate 23.4 is provided on the top of the collection box 23, and a plurality of ventilation holes are provided on the top of the steel cover plate 23.4. As shown in Figure 3 shown, a partition plate 23.5 is provided in the collection box 23. The partition plate 23.5 divides the inner cavity of the collection box 23 into a sedimentation tank 23.2 and a clean water tank 23.1. The sedimentation tank 23.2 is communicated with the sewage collecting pipe 18 to collect the sewage generated after flushing. A circulation port 23.3 is provided on the partition plate 23.5. After the sewage in the sedimentation tank 23.2 is sedimented, the upper clean water can flow into the clean water tank 23.1 through the circulation port 23.3, so as to realize the recycling of water resources and reduce waste. As shown in Figure 2As shown in the figure, a suction pump 19 is provided at the top of the steel cover plate 23.4 above the clear water tank 23.1. The inlet of the suction pump 19 is connected to a suction pipe 17, and the suction pipe 17 extends into the clear water so that the suction pump 19 can pump out the clear water in the clear water tank 23.1. The confluence pipe 22 is communicated with the outlet of the suction pump 19, so that the water source pumped out by the suction pump 19 from the suction pipe 17 flows through the confluence pipe 22 to each flushing pipe.

[0033] During use: Start the sewage cleaning program. Turn on the suction pump 19, and then turn on the first-stage valve 13 and the sewage discharge valve 16. The high-pressure water flows through the suction pipe 17, the confluence pipe 22, the first-stage valve 13, and the first-stage flushing pipe 9 to reach the first-stage nozzle 5, and starts to flush the sludge at the highest position of the two sewage discharge slopes. After flushing for a period of time, the control program closes the first-stage valve 13, and at the same time turns on the second-stage valve 12. The high-pressure water flows through the suction pipe 17, the confluence pipe 22, the second-stage valve 12, and the second-stage flushing pipe 8 to reach the second-stage nozzle 4, and flushes the corresponding lower parts of the two sewage discharge slopes. Similarly, turn on the third-stage and fourth-stage valves in sequence, so that the corresponding nozzles flush the corresponding parts of each sewage discharge slope. The muddy sewage generated flows down from the sewage discharge slope and gathers into the corresponding sewage collection tank 14, and automatically flows to the sewage discharge port 15 under the action of the inclined bottom wall of the tank and the gravity of the sewage itself, and then flows through the sewage discharge port 15 to the sewage discharge pipe 21, and then flows through the sewage confluence pipe 18 to the sedimentation tank 23.2. The sewage in the sedimentation tank 23.2 is sedimented, and the clear water in the upper part flows from the circulation port 23.3 to the clear water tank 23.1. The suction pump 19 pumps the clear water to each flushing pipe to complete the cyclic sewage cleaning; after flushing stage by stage, all the control valves of all the flushing pipes are opened at the same time, and all the nozzles flush the sewage discharge slope until there is no sludge at the outlet of the sewage confluence pipe 18, and then close the sewage discharge valve 16. Finally, turn on the control valves at all levels to inject clear water into the cleaning box 1. When the water level reaches the required height, the suction pump 19 stops running and all the valves are closed.

[0034] In other embodiments, the sewage confluence plate may not be provided, and an inclined block is provided at the bottom of the box body. A U-shaped groove is provided on the inclined block, and the inclined block itself forms a sewage collection tank. The bottom wall of the U-shaped groove is inclined to form the bottom wall of the sewage collection tank. One side wall of the U-shaped groove is closely attached to the vertical plate section of the sewage discharge plate, and the other side wall is closely attached to the inner wall of the cleaning box.

[0035] In other embodiments, when the sewage discharge valve is provided, the sewage discharge valve can be set as a manual valve.

[0036] In other embodiments, when setting the control mode of the sewage discharge pipe, no sewage discharge valve is provided on the sewage discharge pipe, and only one sewage discharge valve is provided on the sewage confluence pipe. At this time, the sewage discharge valve controls whether the two sewage discharge pipes discharge sewage at the same time; in other embodiments, the sewage discharge valve can also be not provided, and at this time the sewage generated by flushing directly flows to the collection box.

[0037] In other embodiments, the sewage collecting pipe may not be provided, and in this case, the two sewage discharge pipes are respectively communicated with the collecting box.

[0038] In other embodiments, when arranging the sewage discharge slope, one sewage discharge slope may be provided. In this case, the highest point of the sewage discharge slope contacts the inner wall of the cleaning box, and a sewage collecting tank is provided at the lowest point of the sewage discharge slope. There is only one sewage collecting tank and one sewage discharge port.

[0039] In other embodiments, the confluence pipe may not be provided, and in this case, each flushing pipe is respectively connected with a suction pump.

[0040] In other embodiments, when controlling the flushing pipes, whether each flushing pipe is supplied with water can be controlled by the same control valve. In this case, each flushing pipe is connected with the same control valve.

[0041] In other embodiments, when setting the water outlet structure, it can be set as a water outlet hole.

[0042] In other embodiments, when arranging the flushing pipes, the middle flushing pipe can be set to one, three or four; in other embodiments, the middle flushing pipe may not be provided.

[0043] In other embodiments, the partition board may not be provided. In this case, the bottom end of the suction pipe can be set at a relatively high position to avoid sucking sewage.

[0044] In other embodiments, the collecting box may not be provided. The sewage discharge pipe can be communicated with the sewer to directly discharge the sewage into the sewer. In this case, the suction pipe can be connected to the water supply pipe. When in use, opening the water supply pipe allows the water source to flow to the confluence pipe, and the flushed sewage flows into the sewer from the sewage discharge pipe.
