Description

TECHNICAL FIELD

[0001] The utility model relates to sewage treatment technical field especially sewage treatment is with drawing device. BACKGROUND

[0002] Sewage treatment is the process that carries out purification to sewage to make it reach the water quality requirement of being discharged into a water body or reused, and is widely applied in each field such as building, agriculture, traffic, energy, petrochemical, environmental protection, city landscape, medical treatment, catering and so on, and more and more goes into the daily life of ordinary people. Before purifying and treating sewage, due to more sewage needing to be treated, the sewage is often placed in a sewage pool, and some suspended matters in the sewage can fall into the pool bottom for a long time, with the sedimentation of day after day, more and more sludge can be accumulated in the bottom of the sewage pool, resulting in that the capacity of the sewage pool is smaller and smaller, and also causing a certain influence on subsequent sewage treatment.

[0003] The general water pumping equipment currently used includes a water pumping pump and an output pipe, the water pumping pump is placed in the sewage pool, the water pumping pump is connected with the output pipe, one end of the output pipe is placed at the bottom of the sewage pool, and the other end of the output pipe extends out of the sewage pool, the water pumping equipment can pump away the sludge deposited when collecting the sewage in the sewage pool, but in actual use, due to the fixed position of the water pumping pump, for a large-area sewage pool, the water pumping pump can only pump the sludge near the water pumping pump, and the sludge accumulated in other positions cannot be cleaned. SUMMARY

[0004] The utility model discloses a sewage treatment drawing device, which can solve the problem that the existing water pumping equipment cannot clean large-area sludge.

[0005] The sewage treatment drawing device of the utility model adopts the following technical scheme: a sewage treatment drawing device, including a water pumping pump, the water outlet waterway of the water pumping pump is connected with a branch waterway, a jetting structure for jetting high-pressure water pumped out by the water pumping pump to the surrounding of the water pumping pump is arranged on the branch waterway, so that the sludge that cannot be pumped out by the water pumping pump is scattered and mixed in water to flow to the water pumping pump and be pumped out.

[0006] The present invention improves existing sewage treatment extraction devices. When in use, the present invention turns on the water pump, and the sewage extracted by the water pump is transported along the outlet waterway to other equipment outside the sewage pool. The outlet waterway of the water pump is connected to a branch waterway, and a jet structure is provided on the branch waterway. The water extracted by the water pump has high pressure, and the high-pressure water enters the jet structure from the branch waterway. The jet structure sprays the high-pressure water onto the sludge in other areas that the water pump cannot extract, and disperses and mixes the sludge in the water, and then flows to the water pump and is extracted by the water pump. This solves the problem that existing pumping equipment cannot clean the sludge at the far end of the water pump, and has a better cleaning effect on the sewage pool.

[0007] Furthermore, the water outlet of the water pump is connected to an output pipe, which is provided with a diverter pipe, the diverter pipe forming the branch waterway, and the injection structure is connected to the diverter pipe. This arrangement allows the original water pump and output pipe to be retained, and the diverter pipe and injection structure are connected at the output pipe, which saves costs and is easy to manufacture.

[0008] Furthermore, the water pump is arranged vertically with its water inlet facing downward, and the injection structure includes two or more diverter nozzles circumferentially distributed around the vertical axis of the water pump, each of which covers the water pump internally. The injection structure includes two or more diverter nozzles circumferentially distributed around the vertical axis of the water pump, each of which covers the water pump internally, ensuring that sludge in a wider range around the water pump can be injected, achieving a good cleaning effect.

[0009] Furthermore, the diverter nozzle is rotatably arranged around the vertical axis of the water pump, and the diverter nozzle is sealed and rotatably connected to the diverter pipe. The diverter nozzle is arranged as a rotating structure, which has a wider spray range, and all directions are within the spray range, and the cleaning effect is good.

[0010] Furthermore, the diverter nozzle is connected to a driving device for driving the diverter nozzle to rotate. Since the rotation resistance in sewage is large, the driving device drives the diverter nozzle to rotate better, thereby ensuring a better cleaning effect.

[0011] Furthermore, the drive device is located at the top of the water pump, with the rotary output end extending upward. The tops of the multiple diversion nozzles converge through a radially inwardly extending confluence section to form a confluence joint. The rotary output end is connected to the confluence joint, and the diversion pipes extend downward from the top and are sealed and rotatably connected to the confluence joint. This arrangement makes the entire sewage treatment extraction device compact, space-saving, and more stable.

[0012] Furthermore, the injection ports on the diversion nozzle are distributed up and down along the diversion nozzle and face different directions. The injection ports are distributed up and down and face different directions to ensure that the injection direction is dispersed in multiple directions, the sludge is injected into a wider range and the cleaning effect is better.

[0013] Furthermore, a flip cover is hingedly connected to the upper side of the outer end of the spray port. The flip cover blocks the spray port under its own weight and is pushed open by the spray pressure. When the spray port is spraying water, the flip cover is pushed open by the water pressure. When water is not spraying, the flip cover automatically closes under its own weight, blocking the spray port, preventing impurities and sludge from accumulating in the spray port and affecting the next use.

[0014] Furthermore, the lower end of the diverter nozzle is provided with a fixed assembly fixed to the bottom of the sewage tank, and the upper end of the fixed assembly is provided with a rotation support structure for rotatably supporting the diverter nozzle. The fixed assembly rotatably supports the diverter nozzle, ensuring the structural stability of the diverter nozzle, improving the reliability of the transfer assembly, and is not affected by other resistance during rotation, thereby extending the service life.

[0015] Furthermore, the fixed assembly includes a fixed base, the top of which is fixedly connected to an outer connecting ring and an inner connecting ring, the water pump being located in the inner connecting ring, the adjacent surfaces of the outer connecting ring and the inner connecting ring being provided with a chute, the lower end of each diversion nozzle being connected to a rotating ring, the rotating ring extending into the chute and rotating in engagement with the chute wall. The arrangement of the outer connecting ring and the inner connecting ring having adjacent surfaces provided with a chute is convenient to manufacture and has a simple structure, and the rotating ring extending into the chute and rotating in engagement with the chute wall provides stable rotation and a stable and good rotation effect.

[0022] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0023] Specific embodiment 1 of the sewage treatment extraction device of the present utility model:

[0024] The utility model of the sewage treatment extraction device is as follows Figure 1-5 As shown, a sewage treatment extraction device includes a water pump 3 inside a sewage pool 1. The water pump 3 is vertically arranged with the water inlet facing downward. An output pipe 4 is fixedly connected to the water outlet of the water pump 3. The output pipe 4 extends through the sewage pool 1 to the outside of the sewage pool 1. A tee 5 is provided on the output pipe 4 near the water pump 3. The tee 5 is connected to a diversion pipe 6. The sewage pumped out by the water pump 3 passes through the tee 5 to the diversion pipe 6 to form a branch waterway. A spray structure is provided at the water outlet of the diversion pipe 6 to spray the high-pressure water pumped out by the water pump 3 to the surrounding area of ​​the water pump 3, so as to disperse and mix the sludge that cannot be pumped out by the water pump 3 into the water so that it flows to the water pump 3 for extraction. The sludge at the far end of the water pump that cannot be cleaned by the water pump is removed, which has a better cleaning effect on the sewage pool.

[0025] In this embodiment, a fixing assembly 2 is installed at the inner center of the sewage pool 1, and a water pump 3 is fixedly connected to the inner part of the fixing assembly 2. The water pump 3 is installed at the center of the bottom through the fixing assembly 2 so that it can extract sewage from the bottom. The water pump 3 adopts a liquid pump that is more suitable for extracting mixtures such as sludge. By starting the water pump 3, the sludge and sewage extracted by the water pump 3 are transported to the next treatment equipment through the output pipe 4. After passing through the tee 5, part of the sewage flows to the injection structure through the diversion pipe 6. The diversion pipe 6 extends to the water pump 3. Above, the outlet of the diverter pipe 6 is covered with a diverter nozzle 7, and the outer side and bottom circular array of the diverter nozzle 7 are fixedly connected with a jet port 8. The diverter nozzle 7 and the jet port 8 constitute the jet structure. Part of the extracted sewage is passed through the conveying pipe 6 to the diverter nozzle 7 through the tee 5, and then sprayed to the surroundings from the jet port 8. Since the sewage extracted by the water pump 3 has high pressure, the sewage sprayed from the jet port 8 will be sprayed to the sludge in other ranges that the water pump 3 cannot reach, so that it is dispersed and mixed into the water so that it flows to the water pump 3 and is extracted.

[0026] Specifically, the fixed assembly 2 comprises a fixed base 201, which is an L-shaped support leg arranged radially and is fixedly connected to the inner surface of the bottom of the sewage tank 1 by a hexagonal bolt. The top of the fixed base 201 is fixedly connected with an outer connecting ring 202 and an inner connecting ring 203. The adjacent surfaces of the outer connecting ring 202 and the inner connecting ring 203 are provided with a sliding groove 204. The lower end of each shunt nozzle 7 is connected to a rotating ring 14, which extends into the sliding groove 204 and is rotationally connected with the sliding groove 204. The inner part of one of the fixed bases 201 is provided with a through hole 205, through which the output pipe 4 extends to the outside. The rotating ring 14 is clamped in the sliding groove 204, thereby fixing the position of the shunt nozzle 7. The through hole 205 provides an additional support point for the connection between the output pipe 4 and the water pump 3, thereby preventing the excessive accumulation of sludge and sewage above the output pipe 4 from causing excessive pressure on the pipe and loosening the connection between the output pipe 4 and the water pump 3.

[0027] Specifically, the outer side of the shunt nozzle 7 is provided with upwardly and downwardly distributed and differently directed injection ports 8. The upwardly and downwardly distributed and differently directed injection ports 8 can spray a large area of the inner surface of the sewage tank 1. When the water level is low, the injection ports 8 can spray the side wall, thereby diluting the settled sewage and cleaning the layer of sludge adhered to the side of the sewage tank 1. The injection port 8 is a tubular structure with a short length. The top of the water outlet of the injection port 8 is fixedly connected with a hinge 9. The hinge 9 is fixedly connected with a flip cover 10. The flip cover 10 is rotated at the connection of the hinge 9. When the injection port 8 sprays water, the flip cover 10 can be opened by water pressure. When there is no water spraying, the flip cover 10 will automatically drop under the action of gravity to cover the injection port 8, thereby preventing the accumulation of sewage and sludge in the pipe.

[0028] Specifically, the top of the water pump 3 is fixedly connected with a connecting cylinder 11. The inner part of the connecting cylinder 11 is fixedly connected with a motor 12. The top of each shunt nozzle 7 is connected by a radially inwardly extending converging section to form a converging joint 13. The rotating output end of the motor 12 is connected with the converging joint 13. The shunt pipe 6 extends from the side of the water pump to directly above the water pump and is sealingly and rotationally connected with the converging joint 13 from top to bottom. The motor 12 is started to drive the shunt nozzle 7 and the injection port 8 to rotate, thereby uniformly spraying the injection port 8 and further improving the cleaning effect on the bottom and side wall of the sewage tank 1.

[0029] Specifically, the diverter pipe 6 is made of metal material, and the diverter pipe 6 is inserted into the water inlet of the junction 13 of the diverter nozzle 7. The diverter pipe 6 is made of hard material to ensure that the water discharged from the water outlet of the diverter pipe 6 without contacting the junction 13 of the diverter nozzle 7 will still maintain a high-pressure state and enter the diverter nozzle 7. The smaller the matching gap between the diverter pipe 6 and the junction 13 of the diverter nozzle 7, the less sewage will flow out of the gap, further ensuring that the water in the diverter nozzle 7 is in a high-pressure state, so that the sewage can be sprayed farther, and the impact force on the surface of the sewage pool 1 is greater, which is convenient for cleaning.

[0030] Through the above description of the specific embodiment 1 of the sewage treatment extraction device of the utility model, it can be seen that the sewage treatment extraction device of the utility model is provided with a jet structure on the existing sewage treatment extraction device. The jet structure uses the high pressure of water to flush out the sludge deposited inside the sewage pool that cannot be cleaned by the water pump and mix it into the water so that it flows to the water pump to be extracted, which has a better cleaning effect on the sewage pool.

[0031] Of course, the sewage treatment extraction device of the present invention is not limited to the above embodiment. The following also lists several other implementations of the sewage treatment extraction device based on the design concept of the present invention.

[0032] For example, in other embodiments, different from the above-mentioned embodiment 1, the pump casing of the water pump has an internal flow channel connected to the output pipe, the internal flow channel constitutes a branch water channel, and the branch water channel of the internal flow channel extends to the top of the water pump and is connected to the injection structure.

[0033] For example, in other embodiments, different from the above-mentioned embodiment 1, when the water pump is at the edge of the sewage pool, the sludge in the pool far away from the water pump cannot be extracted. At this time, the fixed component is installed in the center of the sewage pool next to the water pump, and the injection structure is rotatably assembled on the fixed component.

[0034] For example, in other embodiments, unlike the above-mentioned embodiment 1, the driving device that drives the diversion nozzle to rotate shares a power structure with the water pump, or the driving device is configured as a hydraulic motor, or the injection ports are all configured as oblique ports and are self-rotating injection structures that can automatically rotate along the same tangential direction under the action of water pressure.

[0035] For another example, in other embodiments, different from the above-mentioned embodiment 1, the upper end of the diverter nozzle is connected to the diverter pipe, and the lower end of the diverter nozzle is suspended.

[0036] Or in other embodiments, the main difference from the above-mentioned embodiment 1 lies in the rotational coordination between the fixed assembly and the diverter nozzle. Specifically, in this embodiment, the structure on the fixed base is an L-shaped connecting ring, and a bearing is provided inside the L-shaped connecting ring, and each diverter nozzle is rotatably connected to the bearing.

[0037] Or in other embodiments, different from the above-mentioned embodiment 1, a diverter pipe is provided on the output pipe, a diverter nozzle is connected to the diverter pipe, and injection holes are distributed up and down on the outer wall of the diverter nozzle and face different directions.

[0038] Or in other embodiments, different from the above-mentioned embodiment 1, the number of the diverter nozzles is large and densely distributed, the lower ends of the diverter nozzles are fixedly connected to the fixed assembly, and no driving device is provided on the diverter nozzles.

[0039] Alternatively, in other embodiments, unlike the above-mentioned embodiment 1, the jet port is a conical structure extending outward with a decreasing diameter, the water pressure of the high-pressure water jetted along the conical structure is greater, and the water outlet end of the jet port is no longer provided with a flip cover.
