Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and specifically to a multiphase circulation sewage treatment device. Background Art

[0002] With the continuous development of modern society and industry, the development of industry is accompanied by the generation of industrial sewage. Therefore, there is a need for a sewage treatment device in the market to treat sewage.

[0003] The Chinese patent discloses "a multiphase circulation sewage treatment device" with the publication number CN216785931U. The utility model includes a protection box and a connecting pipe. A cover plate is hinged to the top of the protection box. An inlet is opened on the left side of the protection box.

The right side of the anoxic box is communicated with an aerobic box. The right side of the aerobic box is communicated with a reaction box. An outlet is opened on the right side of the protection box. The reaction box is communicated with the outlet. Through the cleaning rod, the dirt on the inner wall of the connecting pipe can be cleaned, and both ends of the cleaning rod can clean the openings of the anaerobic box, anoxic box, aerobic box or reaction box, preventing the solids in the sewage from blocking the channel, thus realizing the automatic cleaning of the device, saving labor costs and improving the cleaning efficiency, so as to solve the problem that it is not convenient to clean the device in the prior art.

[0004] The above patent can achieve automatic cleaning inside the pipeline, but there are still the following deficiencies: Since an empty slot is opened on the pipeline for the driven gear to pass through, when a large amount of sewage is transported in the pipeline, sewage will splash out from the empty slot on the pipeline, which requires the operator to clean the area near the pipeline again, increasing the labor intensity of the operator, and the splashed sewage also needs to be re-treated, resulting in poor sewage treatment effect. Summary of the Invention

[0005] The purpose of the present invention is to provide a multiphase circulation sewage treatment device, aiming to solve the problems in the prior art that when a large amount of sewage flows along the pipeline, sewage will splash out from the empty slot on the pipeline, increasing the labor intensity of the operator and resulting in poor sewage treatment effect.

[0008] Preferably, each of the high-pressure nozzles is directed toward one side of the inner wall of the first pipe section.

[0009] Preferably, the pipeline further includes a second pipe section and a third pipe section, and the second pipe section and the third pipe section are respectively provided with filter components to intercept debris from the sewage transported from the first sewage pool to the second sewage pool through the pipeline; The filter assembly comprises a baffle fixedly arranged in the pipeline, the baffle is provided with a plurality of left and right transparent liquid flow holes, and two baffles divide the pipeline into a first pipe section, a second pipe section and a third pipe section.

[0010] Preferably, the filter assembly further comprises a driving source assembly, a cross bar drivingly connected to the driving source assembly, and a hole-shielding assembly drivingly connected to the cross bar; The hole shielding component is rotatably arranged on the baffle.

[0011] Preferably, a main-stage bevel gear is fixedly provided at the lower end of the driving source assembly, and a slave-stage bevel gear is fixedly provided on one side of the crossbar close to the driving source assembly, and the main-stage bevel gear and the slave-stage bevel gear are meshed with each other.

[0012] Preferably, the hole-shielding assembly comprises a driving gear fixedly arranged on the crossbar and a swivel rotatably arranged on the baffle; An arc-shaped rack is provided on the side of the peripheral side of the rotating ring facing the driving gear, and the arc-shaped rack is meshed with the driving gear.

[0013] Preferably, a fixing block is fixedly provided below the pipeline, a sedimentation tank storage tank with an upward opening is provided on the fixing block, and a cleaning component is provided in the sedimentation tank storage tank; The bottom of the swivel ring is provided with an adaptation groove opening downward, a moving plate is inserted in the adaptation groove, an expansion device extending in the vertical direction is arranged on the inner bottom wall of the sedimentation tank storage tank, a clamping seat is fixedly arranged at the movable end of the expansion device, and the clamping seat is rotatably connected with the moving plate, so that the moving plate can be pulled from the adaptation groove into the sedimentation tank storage tank under the stretching of the expansion device.

[0014] A through hole penetrating left and right is formed in the moving plate. When the through hole corresponds to the liquid flow hole, the liquid in the first sewage tank can flow to the second sewage tank through the pipeline.

[0015] Preferably, the cleaning assembly includes a fan assembly fixedly arranged on the inner side wall of the sedimentation tank storage tank and an inclined plane block arranged on the inner bottom wall of the sedimentation tank storage tank to clean sundries on the moving plate descending into the sedimentation tank storage tank.

[0016] Preferably, valves are arranged at both ends of the pipeline.

[0017] The beneficial effects are as follows: 1. A high-pressure nozzle is arranged inside the pipeline. In this way, the liquid flowing into the second sewage tank can be conveyed to the high-pressure nozzle through the main pipeline and the auxiliary pipeline by means of the suction pump. When the liquid reaches the high-pressure nozzle, it will be ejected to powerfully wash the sediment adhering to the inner part of the pipeline.

[0018] 2. With the setting of the hole-blocking assembly, rotating the driving part assembly, the driving part assembly can drive the cross bar to rotate, so that the cross bar drives the swivel ring to rotate through the driving gear and the arc rack. During this process, the rotation of the swivel ring will change the relative position between the through hole and the liquid flow hole, that is, a dislocation phenomenon occurs. By adjusting the size of the filtering hole, the bad condition of the sediment clogging the suction pump can be avoided, thus ensuring the normal operation of the entire sewage filtration system.

[0019] 3. When the swivel ring starts to rotate, since the scraping rod is closely attached to the inner side wall surface of the pipeline, it can effectively drive the scraping rod to rotate accordingly. During the rotation of the scraping rod, the sediment adhering to the inner wall of the pipeline can be comprehensively and carefully cleaned. This way of rotating while sticking to the wall can ensure that the scraping rod is in full contact with the sediment, so as to scrape off the sediment stubbornly adhering to the inner wall more thoroughly.

[0020] 4. When the moving plate on the swivel is blocked, the telescopic device is activated to drive the clamping seat downward, thereby driving the moving plate away from the swivel. When the moving plate descends into the sediment storage tank, under the action of the fan assembly, the sediment blocking the through-hole on the moving plate can be cleaned, and the cleaned sediment will move along the inclined plane block into the collection area for easy cleaning.

DETAILED DESCRIPTION OF THE INVENTION

[0023] The following further describes the specific embodiments of the multiphase circulating sewage treatment equipment of the present invention in conjunction with the accompanying drawings.

[0024] As Figures 1 - 10 shown, the multiphase circulating sewage treatment equipment is mainly used for the situation where sediment accumulates in the pipeline 3 after long-term use when sewage is transported between sewage tanks through the pipeline 3. In this solution, after the sewage in the first sewage tank 1 flows into the second sewage tank 2, the filtered sewage is transported to the high-pressure nozzle 903 through a suction pump, so as to realize the high-pressure nozzle 903 flushing the sediment attached to the inner wall of the pipeline 3 and improve the transportation effect of the pipeline 3.

[0025] In this embodiment, the principles and structures of the first sewage tank 1 and the second sewage tank 2 are prior arts and will not be elaborated in detail here.

[0026] In this embodiment, as Figure 1 and Figure 2 shown, the sewage treatment equipment includes a first sewage tank 1 and a second sewage tank 2. The first sewage tank 1 is provided with a first inlet pipe 4 and a first outlet pipe, and the second sewage tank 2 is provided with a second inlet pipe 6 and a second outlet pipe 7. A pipeline 3 is connected between the first outlet pipe on the first sewage tank 1 and the second inlet pipe 6 on the second sewage tank 2. Through the setting of the pipeline 3, the sewage in the first sewage tank 1 can be transported into the second sewage tank 2. In this embodiment, there are several sewage tanks. In this solution, only two are shown, namely the first sewage tank 1 and the second sewage tank 2.

[0027] Valves are provided at both ends of the pipeline 3. Through the setting of the valves, the pipeline 3 can be closed or opened to transport the sewage.

[0028] As Figure 4 , Figure 5 , Figure 7 and Figure 10 shown, a suction pump is provided in the second sewage tank 2. The suction pump sucks the sewage in the second sewage tank 2, and then transports the sewage to the high-pressure nozzle 903 through the main pipeline 901 and the auxiliary pipeline 902 to clean the sediment on the inner wall of the pipeline 3.

[0029] Specifically, the pipeline 3 includes a first pipe section 301 close to the first outlet pipe. An annular buckle cover 8 is fixedly provided on the inner wall of the first pipe section 301. A flushing assembly connected to the suction pump through a hose is provided in the annular buckle cover 8. The annular buckle cover 8 is provided with an installation slot hole adapted to the flushing assembly. The settings of the annular buckle cover 8 and the installation slot hole can support the flushing assembly and prevent the flushing assembly from tilting and deviating after long-term use.

[0030] In this embodiment, the structures and principles of the suction pump, the main pipeline 901, and the auxiliary pipeline 902 are all prior arts and will not be elaborated here in detail.

[0031] The flushing assembly includes a main pipeline 901, several auxiliary pipelines 902 connected to the main pipeline 901, and high-pressure nozzles 903. The main pipeline 901 is communicated with the hose of the suction pump. In this embodiment, the hose of the suction pump is the discharge port of the suction pump; there are several mounting slots on the annular buckle cover 8, and they are arranged at intervals in a fan-shaped array along the axis of the annular buckle cover 8; each mounting slot corresponds to an auxiliary pipeline 902, and one end of each auxiliary pipeline 902 far from the main pipeline 901 is fixedly connected to the high-pressure nozzle. After the suction pump is started, the suction pump can transport the sewage in the second sewage tank 2 to the high-pressure nozzle 903 through the main pipeline 901 and the auxiliary pipeline 902, and spray it out through the high-pressure nozzle 903 to clean the sediment on the inner wall of the pipeline 3. Each high-pressure nozzle 903 faces the inner wall side of the first pipe section 301.

[0032] As Figure 3 , Figure 4 and Figure 8 shown, the sewage flowing from the first sewage tank 1 into the second sewage tank 2 can intercept sediment, avoiding the situation that the sediment in the second sewage tank 2 is too much and causing the suction pump to be blocked.

[0033] Specifically, the pipeline 3 further includes a second pipe section 302 and a third pipe section 303. Filtering components are respectively arranged in the second pipe section 302 and the third pipe section 303 to intercept sundries in the sewage transported from the first sewage tank 1 to the second sewage tank 2 through the pipeline 3; the filtering component includes a baffle 10 fixedly arranged in the pipeline 3 and a hole-blocking component 14 rotatably arranged on the baffle 10. Several liquid-flowing holes that are transparent from left to right are opened on the baffle 10. A moving plate 26 is arranged on the hole-blocking component 14, and a through hole 15 that is transparent from left to right is opened on the moving plate 26. When the through hole 15 corresponds to the liquid-flowing hole, the liquid in the first sewage tank 1 can flow through the pipeline 3 to the second sewage tank 2.

[0034] The two baffles 10 divide the pipeline 3 into a first pipe section 301, a second pipe section 302, and a third pipe section 303. Through the settings of the second pipe section 302 and the third pipe section 303, the sewage can be filtered and intercepted at multiple levels, improving the effect of sediment removal.

[0035] As Figure 4 and Figure 5 shown, by rotating the hole-blocking component 14, the relative positions of the through hole 15 and the liquid-flowing hole can be adjusted. The through hole 15 and the liquid-flowing hole cooperate with each other to form the structure of an intercepting hole. When the position of the through hole 15 changes, the size of the intercepting hole space formed by the cooperation of the through hole 15 and the liquid-flowing hole changes to intercept sediments of different sizes.

[0036] Specifically, the filtering component further includes a driving source component 12 and a cross bar 13 that is drivingly connected to the driving source component 12; the hole covering component 14 is rotatably arranged on the baffle 10, and when the through hole 15 corresponds to the liquid flow hole, the liquid in the first sewage tank 1 can flow to the second sewage tank 2 through the pipeline 3. In this embodiment, the driving source component 12 includes a vertical rod and a knob, and the vertical rod is drivingly connected to the cross bar 13 to rotate the cross bar 13.

[0037] In this embodiment, the operator rotates the knob, and the knob can drive the vertical rod to rotate. When the vertical rod rotates, it can drive the cross bar 13 to rotate.

[0038] A main stage bevel gear 16 is fixedly arranged at the lower end of the vertical rod, and a secondary stage bevel gear 17 is fixedly arranged on one side of the cross bar 13 close to the driving source component 12. When the vertical rod rotates, it can drive the main stage bevel gear 16 to rotate. When the main stage bevel gear 16 rotates, since the main stage bevel gear 16 and the secondary stage bevel gear 17 are meshed with each other, it can drive the secondary stage bevel gear 17 to rotate, and then drive the cross bar 13 to rotate.

[0039] The hole covering component 14 includes a driving gear 1401 fixedly arranged on the cross bar 13 and a rotating ring 1402 rotatably arranged on the baffle 10; the through hole 15 is opened on the moving plate 26. When the cross bar 13 rotates, it can drive the driving gear 1401 on the cross bar 13 to rotate. An arc-shaped rack 18 is arranged on one side of the circumferential surface of the rotating ring 1402 facing the driving gear 1401, and the arc-shaped rack 18 is meshed with the driving gear 1401. When the driving gear 1401 rotates, since the driving gear 1401 and the arc-shaped rack 18 are meshed with each other, it can drive the rotating ring 1402 to rotate. When the rotating ring 1402 rotates, it can adjust the position of the through hole 15 to intercept sediments of different sizes.

[0040] In other embodiments, the arc-shaped rack 18 can be arranged on a section of the rotating ring 1402 or on the entire circumferential surface of the rotating ring 1402 for adjustment. When the rotating ring 1402 rotates, it only needs to rotate a certain distance and move relative to the liquid flow hole on the baffle 10, without the need for large-angle rotation, so as to avoid the situation where the moving plate 26 cannot be pulled out when the rotating ring 1402 rotates at a large angle.

[0041] As Figure 6 and Figure 9 shown, when the moving plate 26 is used for a long time, sediments will accumulate in the through hole 15 on the moving plate 26. When cleaning is required, the moving plate 26 is lowered into the sedimentation tank storage tank 24 and cleaned through the cleaning component 25.

[0042] Specifically, a fixing block 23 is fixedly arranged below the pipeline 3. A sedimentation tank storage groove 24 with an upward opening is formed in the fixing block 23, and a cleaning assembly 25 is arranged in the sedimentation tank storage groove 24; an adaptation groove with a downward opening is formed at the bottom of the rotating ring 1402, and the moving plate 26 is inserted into the adaptation groove. In this embodiment, a rubber skin is arranged in the adaptation groove. When the moving plate 26 can move downward under the action of the clamping seat 28, and when the clamping seat 28 moves upward, the moving plate 26 can be pushed into the adaptation groove. Since the rubber skin in the adaptation groove and the moving plate 26, after the moving plate 26 is inserted into the adaptation groove, the moving plate 26 will not rotate. An expansion device 27 extending in the vertical direction is arranged on the inner bottom wall of the sedimentation tank storage groove 24. The movable end of the expansion device 27 is fixedly provided with a clamping seat 28, and the clamping seat 28 is rotatably connected with the moving plate 26. In this embodiment, as Figure 6 shown, a limiting column is fixedly arranged on the clamping seat 28, and an annular groove adapted to the limiting column is formed on the surface of the moving plate 26 to prevent the moving plate 26 from detaching from the clamping seat 28. Moreover, during the up and down movement of the clamping seat 28, the moving plate 26 can also be pulled into the sedimentation tank storage groove 24, so that the moving plate 26 can descend from the adaptation groove into the sedimentation tank storage groove 24 under the stretching of the expansion device 27, and under the action of the cleaning assembly 25, the sediment in the through hole 15 on the moving plate 26 is cleaned. After the expansion device 27 is started, the expansion device 27 can drive the clamping seat 28 to move up and down, and when the clamping seat 28 moves up and down, it can drive the moving plate 26 to move up and down. When the moving plate 26 descends into the sedimentation tank storage groove 24, as Figure 9 shown.

[0043] In this embodiment, the expansion device 27 adopts an electric telescopic rod or a hydraulic telescopic rod. The structures and principles of the electric telescopic rod and the hydraulic telescopic rod are prior arts and will not be elaborated in detail here.

[0044] The cleaning assembly 25 includes a fan assembly 2501 fixedly arranged on the inner side wall of the sedimentation tank storage groove 24 and an inclined plane block 2502 arranged on the inner bottom wall of the sedimentation tank storage groove 24. The fan assembly 2501 is a prior art and will not be elaborated in detail here to clean the sundries on the moving plate 26 that descends into the sedimentation tank storage groove 24. Start the fan assembly 2501 so that the sediment in the through hole 15 on the moving plate 26 can be cleaned. Since the inclined plane block 2502 is arranged in the sedimentation tank storage groove 24, the sediment blown off by the fan assembly 2501 can slide to the sediment treatment area. In this embodiment, the lowest end of the inclined plane block 2502 is connected with the sediment treatment area to collectively collect and treat the sediment.

[0045] In other embodiments, a micro camera may be installed in the second pipe section 302 and the third pipe section 303 to monitor in real time the coordination between the movable plate 26 and the baffle 10. In this embodiment, the principle and structure of the micro camera are prior art and will not be described in detail.

[0046] Working principle: sewage is transported to the first sewage pool 1 through the first liquid inlet pipe 4. When the valve on the pipeline 3 is opened, the sewage can flow to the second sewage pool 2 through the pipeline 3. When the sewage passes through the pipeline 3, the sewage will flow into the second sewage pool 2 through the interception hole formed by the flow hole on the baffle 10 and the through hole 15 on the movable plate 26 to intercept the sediment in the sewage. Manually turn the knob, the knob can drive the vertical rod to rotate, and when the vertical rod rotates, it can drive the main stage bevel gear 16 to rotate, and the main stage bevel gear When the main bevel gear 16 rotates, since the main bevel gear 16 and the secondary bevel gear 17 are meshed with each other, the secondary bevel gear 17 can be driven to rotate, thereby driving the cross bar 13 to rotate. When the cross bar 13 rotates, the driving gear 1401 on the cross bar 13 can be driven to rotate. When the driving gear 1401 rotates, since the driving gear 1401 and the arc-shaped rack 18 are meshed with each other, the rotating ring 1402 can be driven to rotate. When the rotating ring 1402 rotates, the position of the through hole 15 can be adjusted to intercept sediments of different sizes. When the movable plate 26 is used for a long time, the sediment will accumulate in the through hole 15 on the movable plate 26, and the telescopic device 27 is driven to start. The telescopic device 27 can drive the clamping seat 28 to move up and down, and when the clamping seat 28 moves up and down, it can drive the movable plate 26 to move up and down. Since the clamping seat 28 is fixed with a limit column, the movable plate 26 can be pulled into the sedimentation tank storage tank 24, and the fan assembly 2501 is started to clean the sediment in the through hole 15 on the movable plate 26. A slope block 2502 is provided in the groove 24, so the sediment blown off by the fan assembly 2501 can slide to the sediment treatment area; after the cleaning is completed, the telescopic device 27 is started to push the movable plate 26 into the adapter groove of the rotating ring 1402; after long-term use, after the suction pump is started, the suction pump can transport the sewage in the second sewage pool 2 through the main pipe 901 and the auxiliary pipe 902 to the high-pressure nozzle 903, and spray it out through the high-pressure nozzle 903 to clean the sediment attached to the inner wall of the pipeline 3.

[0047] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is to filter the sewage in multiple stages and then transport the sewage to the high-pressure nozzle 903 to clean the attachments on the inner wall of the pipe, which can not only improve the cleaning effect, but also avoid splashing at the opening of the pipe 3, and reduce the investment cost. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
