Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and particularly to a sludge discharging device for sewage treatment. Background Art

[0002] Sewage treatment refers to the removal of pollutants in sewage through physical, chemical or biological methods to meet water quality standards so that it can be reused or discharged into the environment. The goal of sewage treatment is to protect water bodies, avoid pollution, and improve the recycling of water resources.

[0003] During the process of sewage treatment and purification, one of the important steps is to collect sewage, which enters the sedimentation tank through various levels of treatment for sedimentation. After a long time of sedimentation, the sludge in the sewage naturally falls due to gravity factors and finally accumulates at the bottom of the inner cavity of the sedimentation tank. Therefore, in order to increase the utilization rate of the sedimentation tank, it is necessary to clean the sludge in the sedimentation tank, and a sludge discharging device is used at this time.

[0004] However, in the prior art, during the use of the sludge discharging device, usually a sludge suction pump is used to suck the sludge into the sludge conveying pipeline. When the solid content in the sludge is too high and the viscosity is large, it is extremely easy to form blockage in the pipeline. At this time, the conveying efficiency of the sludge will be greatly reduced, resulting in the sludge not being able to be discharged from the treatment system in time, affecting the smooth progress of the entire sewage treatment process; At the same time, the traditional sludge discharging device lacks an adjustment mechanism inside. This leads to the need to stop the machine to clean the inside of the pipeline when an abnormality occurs inside the pipeline during the sludge discharging process. The shutdown time is relatively long, which undoubtedly affects the sewage treatment efficiency, the overall degree of intelligence is low, and it cannot achieve adaptive adjustment when an abnormality occurs.

The horizontal pipe is fixedly connected to the annular housing through a pipeline. A cavity is provided inside the annular housing. The cavity is communicated with the nozzle.

[0011] Preferably, the control panel includes a server, a data monitoring module and a remote supervision terminal; The data monitoring module monitors the working environment and process inside the fixed pipe, obtains corresponding abnormal deviation values through process analysis and processing. If the abnormal deviation value exceeds the set threshold, a sludge discharging abnormal signal is generated. Otherwise, a sludge discharging normal signal is generated, and the sludge discharging abnormal signal is sent to the remote supervision terminal through the server; When the remote supervision terminal receives the sludge discharging abnormal signal, it enters a multi-level response state and issues corresponding warnings.

[0012] Preferably, the multi-level response includes a first-level response, a second-level response and a third-level response; The specific operation process of the first-level response includes: the electromagnetic ring sends a high-frequency pulse current, and the airbag in the middle section of the fixed pipe inflates and expands, causing local diameter reduction inside the fixed pipe; At the same time, the data monitoring module continuously monitors the operation state of the equipment, and obtains the abnormal deviation value at the current moment through process analysis and processing of the currently collected data.

[0015] The beneficial effects of the present invention are as follows: The present invention is through the combined use of components such as a spiral fan blade, an air bag and a movable scraper. After the sludge is transported to the fixed pipe, the rotating shaft is driven to rotate. The spiral fan blade is used to transport the sludge. During the transportation process, the electromagnetic ring is periodically energized to generate a magnetic field, so as to generate a periodic suction force on the permanent magnet block. The electromagnetic force is used to drive the permanent magnet block to move towards the inner wall of the fixed pipe, and then drive the movable scraper to extend from the spiral fan blade, so that the front end of the movable scraper slides closely against the pipe wall to remove the accumulated mud in the gap between the spiral fan blade and the pipe wall. That is, when the electromagnetic ring is triggered, the movable scraper synchronously expands and contracts radially during rotation, forming a "rotation + scraping" compound movement.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0019] Embodiment 1: This embodiment is used to solve the problem that in the prior art, during the use of the mud discharging device, usually a sludge suction pump is used to suck the sludge into the sludge conveying pipeline. When the solid content in the sludge is too high and the viscosity is large, it is extremely easy to form a blockage in the pipeline. At this time, the sludge conveying efficiency will drop significantly, resulting in the sludge not being able to be discharged from the treatment system in time, affecting the smooth progress of the entire sewage treatment process.

[0020] Please refer to Figure 1 - Figure 8As shown in the figure, this embodiment is a sludge discharging device for sewage treatment, including a fixed pipe 1. A rotating shaft 11 is movably installed in the fixed pipe 1, and a spiral fan blade 12 is fixedly installed on the rotating shaft 11. A sludge discharging component 3 is fixedly installed in the fixed pipe 1. The sludge discharging component 3 includes an airbag 31, a permanent magnet block 32, an electromagnetic ring 33, and a movable scraper 34. There are multiple airbags 31, and the airbags 31 are fixedly installed on the inner wall of the fixed pipe 1. The permanent magnet block 32 is movably installed on the rotating shaft 11, and the movable scraper 34 is fixedly connected to the permanent magnet block 32.

[0021] The electromagnetic ring 33 and the permanent magnet block 32 are adapted in position. The movable scraper 34 is located in the gap between the spiral fan blades 12. There are multiple airbags 31, and the electromagnetic ring 33 is located between the airbags 31. The sludge discharging component 3 further includes a horizontal pipe 35, a movable rod 36, and a nozzle 37. The horizontal pipe 35 is fixedly installed on one side of the fixed pipe 1. The movable rod 36 is movably installed in the horizontal pipe 35. The nozzle 37 is fixedly installed in the gap of the electromagnetic ring 33. The horizontal pipe 35 is fixedly connected to the nozzle 37 through a pipeline.

[0022] A feed pipe is fixedly installed at the top of the fixed pipe 1. An outlet is opened at one end of the fixed pipe 1 away from the feed pipe. A motor is fixedly installed at one end of the fixed pipe 1. A worm 38 is fixedly installed at the output end of the motor. The worm 38 is fixedly connected to the rotating shaft 11. The pitch of the spiral fan blade 12 gradually decreases from the feed pipe to the outlet. By driving the worm 38 to rotate through the motor, the rotating shaft 11 is driven to rotate, so as to convey the sludge through the spiral fan blade 12. Through the gradient change of the pitch of the spiral fan blade 12, a wide pitch at the inlet prevents blockage, and a narrow pitch at the outlet increases pressure.

[0023] A vertical pipe 39 is fixedly installed on the rotating shaft 11. The permanent magnet block 32 is movably installed in the vertical pipe 39. A spring is fixedly installed at the bottom of the permanent magnet block 32, and one end of the spring is fixedly connected to the inner wall of the vertical pipe 39. A connecting rod 40 is fixedly installed at the top of the permanent magnet block 32, and the connecting rod 40 is fixedly connected to the movable scraper 34. A rotating rod 41 is movably installed at one end of the fixed pipe 1 close to the motor. A worm gear 42 is fixedly installed at one end of the rotating rod 41. The worm gear 42 is meshed with the worm 38. A turntable 43 is fixedly installed at the end of the rotating rod 41 away from the worm gear 42. An adjusting rod 44 is movably installed on the turntable 43, and the adjusting rod 44 is movably connected to the movable rod 36.

[0024] A piston 45 is fixedly installed inside the horizontal pipe 35. The piston 45 is fixedly connected to the movable rod 36. An air inlet pipe is fixedly installed on one side of the horizontal pipe 35. An annular shell 46 is fixedly installed on the outer wall of the fixed pipe 1. The horizontal pipe 35 is fixedly connected to the annular shell 46 through a pipeline. A cavity is provided inside the annular shell 46, and the cavity is communicated with the nozzle 37. That is, when the motor drives the worm 38 to rotate, the worm gear 42 is driven to rotate by the worm 38, and then the turntable 43 is driven to rotate; Then, through the linkage cooperation of the adjusting rod 44 and the moving rod 36, the piston 45 is driven to reciprocate in the horizontal pipe 35. When the piston 45 moves towards the turntable 43, gas enters the horizontal pipe 35 from the air inlet pipe. When the piston 45 moves away from the turntable 43, the gas is squeezed, enters the annular housing 46 through the pipeline, and is sprayed out from the nozzle 37. The high-speed air flow is used to assist the movement of the sludge, prevent the surface from caking, and reduce the probability of blockage.

[0025] It should be noted that one-way valves are fixedly installed in both the nozzle 37 and the air inlet pipe to control the gas flow and prevent the gas from flowing back and the sludge from entering the nozzle 37.

[0026] That is, after the sludge is transported to the fixed pipe 1, the rotating shaft 11 is driven to rotate, and the spiral fan blade 12 is used to transport the sludge. During the transportation process, the electromagnetic ring 33 is periodically energized to generate a magnetic field, thereby generating a periodic suction force on the permanent magnet block 32. The electromagnetic force is used to drive the permanent magnet block 32 to move towards the inner wall of the fixed pipe 1, and then drive the moving scraper 34 to extend from the spiral fan blade 12, so that the front end of the moving scraper 34 slides closely against the pipe wall to remove the accumulated sludge in the gap between the spiral fan blade 12 and the pipe wall. That is, when the electromagnetic ring 33 is triggered, the moving scraper 34 synchronously expands and contracts radially during rotation, forming a "rotation + scraping" compound movement. At the same time, the moving scraper 34 can complete multiple expansions and contractions within one rotation, and scrape the accumulated sludge at the same position at a high frequency.

[0027] Embodiment 2: This embodiment is used to solve the problem that the traditional sludge discharge device lacks an adjustment mechanism inside, which leads to the need to stop the machine to clean the inside of the pipeline when an abnormality occurs during the sludge discharge process. The downtime is relatively long, which undoubtedly affects the sewage treatment efficiency. The overall degree of intelligence is low, and adaptive adjustment cannot be achieved when an abnormality occurs.

[0028] Please refer to Figure 9 As shown in the figure, the present invention further includes a control panel 2, and a control panel 2 is fixedly installed on one side of the fixed pipe 1. The control panel 2 includes a server, a data monitoring module, and a remote supervision terminal; The specific operation process of the data monitoring module includes: The data monitoring module monitors the working environment and working process inside the fixed pipe 1, obtains the corresponding abnormal deviation value through process analysis and processing. If the abnormal deviation value exceeds the set threshold, a sludge discharge abnormal signal is generated, otherwise a sludge discharge normal signal is generated, and the sludge discharge abnormal signal is sent to the remote supervision terminal through the server.

[0029] Among them, the specific method for obtaining the abnormal deviation value is as follows: The data of the sludge at the discharge port is collected by a pressure sensor and a flowmeter fixedly installed in the fixed pipe 1, that is, the pipeline pressure and the sludge flow rate data at the discharge port are collected. Taking time as the X-axis and each data collection data as the Y-axis, a corresponding coordinate system is constructed. The pressure data and the flow rate data in the unit time are marked on the coordinate system, and the thresholds set for the corresponding data types are plotted in the coordinate system. If a blockage occurs in the fixed pipe 1, the pressure difference at the discharge port gradually increases and its flow rate gradually decreases. At this time, it shows an upward or downward float on the coordinate system respectively. That is, the area of the floating waveform deviation region between the collected data curve and the threshold curve is calculated. The area of the floating waveform deviation region in the unit time is the deviation value, and the unit time is set to 15 minutes.

[0030] If the deviation value exceeds the set threshold and continues to increase, it is inferred that the operating state of the current sludge discharging device is abnormal. At this time, a sludge discharging abnormal signal is generated, and the sludge discharging abnormal signal is sent to the remote supervision terminal through the server.

[0031] It should be noted that the set thresholds are all threshold values artificially set by the personnel in the operation field of the sorting device according to the historical operation failure generation scenarios; if the set thresholds do not match the current scenario, the thresholds are updated to ensure accurate data detection in the current scenario.

[0032] When the remote supervision terminal receives the sludge discharging abnormal signal, it enters a multi-level response state and issues a corresponding warning.

[0033] The multi-level response includes a first-level response, a second-level response and a third-level response; The specific operation process of the first-level response includes: the electromagnetic ring 33 sends a high-frequency pulsed current, and the airbag 31 in the middle section of the fixed pipe 1 is inflated and expanded, so that the internal part of the fixed pipe 1 is locally reduced in diameter; Specifically, a high-frequency pulsed current is sent to the electromagnetic ring 33 in the pipe wall, and the duty cycle is 50%. Thereby, a periodic electromagnetic suction force is generated. The suction force between the permanent magnet block 32 and the electromagnetic ring 33 drives the movable scraper 34 to expand outwards, scraping the gap between the spiral fan blade 12 and the pipe wall, peeling off the attached sludge. The pulsed mode, that is, non-continuous power-on, can reduce energy consumption. At the same time, the high-frequency vibration effectively prevents sludge adhesion. The airbag 31 at the middle end of the fixed pipe 1 is inflated, so that the local diameter of the pipeline is reduced by 15%. After the diameter reduction, the local flow rate is increased, enhancing the scouring force on the blockage point, and only one group of airbags 31 is activated, and the diameter reduction degree is relatively low, reducing the energy consumption of the air pump.

[0034] Meanwhile, the data monitoring module continuously monitors the operating status of the device, and obtains the abnormal deviation value at the current moment through process analysis and processing of the currently collected data. If the abnormal deviation value at the current moment exceeds the set first-level threshold and continues to increase, that is, if the first-level response lasts for 30 seconds and the pressure difference does not fall back or the flow rate further decreases, it is determined as moderate blockage, then a second-level abnormal signal is generated, and the second-level abnormal signal is sent to the remote supervision end through the server; When the remote supervision end receives the second-level abnormal signal, it enters the second-level response state and issues a corresponding warning.

[0035] The specific operation process of the second-level response includes: the high-frequency pulse frequency of the electromagnetic ring 33 is increased, and the air bags 31 at the feed pipe and the air bags 31 at the discharge port are inflated and expanded, so that the inside of the fixed pipe 1 is stepped in diameter reduction; Specifically, the air bag 31 at the feed pipe is reduced in diameter by 10%, and the air bag 31 at the discharge port is reduced in diameter by 20%, so as to form a stepped diameter reduction. The smaller diameter reduction at the inlet avoids inlet blockage, and the larger diameter reduction at the outlet enhances the end scouring force to form a directional flow. After the air bags 31 are linked, the overall flow rate is increased, further impacting the blocked area. At this time, the pulse frequency of the electromagnetic ring 33 is increased, the duty cycle is 70%, the vibration amplitude of the moving scraper 34 is increased, the more stubborn accumulated mud is removed, and by adjusting the current intensity, the suction peak value is increased to enhance the mechanical force.

[0036] Although the number of air bag 31 groups is increased, the diameter reduction ratio is distributed according to demand to avoid high-energy consumption diameter reduction in the whole section. The electromagnetic pulse only increases the frequency at higher loads, rather than running at full load continuously, so as to control the comprehensive energy consumption.

[0037] Meanwhile, the data monitoring module continuously monitors the operating status of the device, and obtains the abnormal deviation value at the current moment through process analysis and processing of the currently collected data. If the abnormal deviation value at the current moment exceeds the set second-level threshold and continues to increase, that is, if the second-level response lasts for 1 minute and the flow rate still does not recover, or the pressure difference rises sharply, it is determined as serious blockage or mechanical failure, then a third-level abnormal signal is generated, and the third-level abnormal signal is sent to the remote supervision end through the server; When the remote supervision end receives the third-level abnormal signal, it enters the third-level response state and issues a corresponding warning.

[0038] The specific operation process of the third-level response includes: all the air bags 31 are inflated to the limit state, so that the internal pipe diameter of the fixed pipe 1 is reduced as a whole; Specifically, all three groups of air bags 31 are inflated to the limit diameter reduction state, with a 10% diameter reduction at the inlet, 15% in the middle reaches, and 20% at the outlet. The overall pipe diameter is reduced to form a high-speed jet flow, which forcibly flushes open the blockage. At the same time, the pressure sensors of the air bags 31 monitor the inflation state to avoid overpressure damage to the pipeline.

[0039] Meanwhile, the data monitoring module continuously monitors the operating status of the equipment, and obtains the abnormal deviation value at the current moment by analyzing and processing the currently collected data. If the abnormal deviation value at the current moment exceeds the set third-level threshold and continues to increase, that is, if the flow rate does not recover within 10 seconds, the sludge input is automatically cut off and the emergency evacuation program is started to prevent the equipment from overloading, and a corresponding warning is issued to prompt manual intervention.

[0040] That is, during the operation of the sludge discharge device, the extracted and identified features are used to accurately evaluate the influence of the collected data. Combining the influence of the collected data itself and the influence on the sludge discharge device, the pertinence of the control of the sludge discharge device is improved. And when a fault occurs, multi-level control can be carried out according to the evaluation results, and corresponding structures are controlled to perform compensatory operations. While avoiding waste of energy, adaptive adjustment inside the pipeline is also realized, fundamentally reducing the impact brought by the fault, improving the operation efficiency of the sludge discharge device, and having a relatively high degree of intelligence.

[0041] Combining Embodiment 1 and Embodiment 2, it can be seen that not only can the data inside the sludge discharge device be collected, the extracted and identified features be used to accurately evaluate the influence of the collected data, and comprehensive and efficient supervision be carried out during use, that is, the collected data range and the preset data range are comprehensively analyzed and compared, so as to obtain relevant evaluation signals, and accordingly, corresponding warnings are sent to the remote supervision end to realize multi-level control of the sludge discharge device. And for abnormal sludge discharge, through the cooperation of the airbag 31 and the movable scraper 34, while controlling the pipe diameter, a "rotation + scraping" composite movement is formed, effectively improving the sludge discharge effect of the device.

A sludge discharge device for sewage treatment according to claim 7, characterized in that, The specific operation process of the second-level response includes: the high-frequency pulse frequency of the electromagnetic ring (33) increases, and the airbags (31) at the feed pipe and the discharge port inflate and expand, causing the inside of the fixed pipe (1) to have a stepped diameter reduction. At the same time, the data monitoring module continuously monitors the operating state of the equipment, and through process analysis and processing of the currently collected data, obtains the abnormal deviation value at the current moment. If the abnormal deviation value at the current moment exceeds the set second-level threshold and continues to increase, a third-level abnormal signal is generated, and the third-level abnormal signal is sent to the remote supervision end through the server. When the remote supervision end receives the third-level abnormal signal, it enters the third-level response state and issues a corresponding warning.

9. The sludge discharging device for sewage treatment according to claim 8, wherein, The specific operation process of the third-level response includes: all the airbags (31) are inflated to the limit state, causing the overall diameter of the internal pipe fittings of the fixed pipe (1) to decrease. At the same time, the data monitoring module continuously monitors the operating state of the equipment, and through process analysis and processing of the currently collected data, obtains the abnormal deviation value at the current moment. If the abnormal deviation value at the current moment exceeds the set third-level threshold and continues to increase, an emergency stop is performed and a corresponding warning is issued.
