Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device with a flow adjustable function. Background Art

[0002] In recent years, with increasingly stringent environmental protection requirements, sewage treatment technology has been continuously upgraded, but there are still some technical bottlenecks in practical applications. Traditional sewage treatment devices usually adopt a fixed flow design, which is difficult to cope with the fluctuation of sewage water impact force, resulting in unstable treatment efficiency; the dosing system and stirring speed often lack dynamic matching with the sewage level, resulting in waste of reagents or inadequate reaction; in addition, the filter is easily clogged by impurities during long-term operation, requiring frequent manual cleaning, which increases maintenance costs.

[0003] Most existing sewage treatment devices use fixed-caliber inlet valves or simple mechanical baffles to control flow, and are unable to dynamically adjust the flow into the treatment tube according to changes in sewage impact force. When the sewage impact force suddenly increases, it may cause the treatment tube to overload and affect the sedimentation or biochemical reaction effect; when the impact force is small, it may cause insufficient equipment utilization. Although there are some electric control valve solutions, they rely on external sensors and complex control systems, which are costly and prone to failure.

[0004] The current dosing system usually adds chemicals based on a preset timing or quantitative mode, and it is difficult to adjust the dosage in real time according to the changes in the sewage level. For example, when the liquid level is low, the dosage may be excessive, resulting in an increase in chemical sludge; when the liquid level is high, the dosage may be insufficient, and the pollutants are not completely degraded. At the same time, the stirring speed is mostly fixed, which cannot match the difference in fluid viscosity caused by the change in liquid level, affecting the uniformity of the mixing of the chemicals. Although the prior art introduces a liquid level sensor linked to a dosing pump, it lacks coordinated optimization with the stirring speed and has a low energy efficiency ratio.

[0005] The filter screen in the sewage treatment device is prone to clogging after intercepting suspended solids for a long time. The traditional method requires stopping the machine for manual flushing or disassembling and replacing the filter screen. Some equipment uses backwashing technology, but it requires additional high-pressure water source and pipelines, and the structure is complicated. Summary of the invention

[0006] The object of the present invention is to provide a sewage treatment device with a flow rate adjustable function to solve the problems raised in the prior art.

[0007] To achieve the above object, the present invention provides the following technical solutions: The sewage treatment device with adjustable flow function comprises a treatment barrel, an adjusting unit, a dosing unit, a stirring unit and a cleaning and filtering unit. The treatment barrel is placed on a horizontal ground, the adjusting unit is fixedly connected to the treatment barrel, the dosing unit is fixedly connected to the treatment barrel, the dosing unit has the function of adjusting the dosing amount according to the liquid level, the dosing unit is electrically connected to the stirring unit, the stirring unit is fixedly connected to the treatment barrel, and the cleaning and filtering unit is fixedly connected to the treatment barrel.

[0008] The treatment cylinder is used to install and fix the regulating unit, dosing unit, stirring unit and cleaning and filtering unit. The regulating unit is used to regulate the sewage flow, the dosing unit is used to add flocculants, the stirring unit is used to fully mix the sewage and flocculants, and the cleaning and filtering unit is used to filter the sewage and treat impurities. After the sewage passes through the regulating unit for adaptive flow adjustment, the dosing unit is used to adaptively add flocculants according to the amount of sewage, and the stirring unit is used to fully stir the sewage and allow the flocculants to fully react and settle. Finally, the self-cleaning filter unit is used to treat impurities and filter the sewage to improve the sewage treatment efficiency.

[0009] Furthermore, the treatment cylinder includes an end cover, on which a drug adding pipe and a water adding pipe are provided, a limiting block is provided at one end of the water adding pipe close to the horizontal ground, and a sewage outlet is provided on the treatment cylinder, on which a baffle is provided.

[0010] Furthermore, the adjustment unit includes a cross bar, a pull rope, an adjustment soft ball, a straight plate, a round rod, a pressure plate, a telescopic plate and a diversion box. The cross bar is fixedly installed inside the water supply pipe. One end of the adjustment soft ball is connected to the cross bar through a pull rope, and the other end is fixedly connected to one end of the straight plate. The other end of the straight plate is fixedly connected to the pressure plate. The straight plate is rotatably connected to the round rod. The round rod is fixedly installed on the inner wall of the treatment cylinder. The pressure plate abuts against the telescopic end of the telescopic plate. The fixed end of the telescopic plate is fixedly installed on the inner surface of the diversion box at one end close to the horizontal ground. The diversion box is fixedly installed on the treatment cylinder. A valve is provided at the fixed end of the telescopic plate.

[0011] Furthermore, the regulating soft ball is filled with a non-Newtonian fluid.

[0012] When the sewage flow impacts the regulating soft ball, the sewage flow suddenly increases. Due to the characteristics of the non-Newtonian fluid itself, it will solidify instantly and bulge upward due to the large impact force, causing the center of gravity of the regulating soft ball to move upward along the water filling pipe, reducing the flow of sewage, avoiding excessive flow impact, causing damage to the internal mechanism, and reducing the service life. After the regulating soft ball solidifies and moves upward, it drives the straight plate to rotate around the round rod. While the straight plate rotates clockwise, the pressure plate at the other end is pressed and the telescopic plate contracts, thereby opening the channel of the diversion box to avoid the increase in flow causing an increase in sewage liquid inside the treatment cylinder and increasing the storage capacity of sewage.

[0013] Furthermore, the dosing unit includes a slide, a float, a push plate, a rack, a gear and a straight column. The slide is fixedly installed on the inner wall of the treatment cylinder, the float is connected to the upper end of the slide by an elastic rope, a slide groove is provided on the slide, the push plate is slidably installed in the slide groove on the slide, the push plate is fixedly connected to the rack, the rack is meshingly connected to the gear, the gear is fixedly connected to the straight column, and the straight column is rotatably connected to the dosing pipe.

[0014] Furthermore, the dosing unit also includes a conductive sheet, a conductive block, a rotating plate, a steel rope, a slider and a fixed cylinder, the conductive sheet is fixedly installed above the push plate, the conductive block is fixedly installed on the surface of one end of the slide cylinder groove away from the horizontal ground, the rotating plate is installed inside the dosing tube, the rotating plate is fixedly connected to the straight column, one end of the steel rope is fixedly connected to the straight column, the steel rope is evenly wound on the straight column, the other end of the steel rope is fixedly connected to the slider, the slider is slidably installed in the fixed cylinder, the fixed cylinder is fixedly connected to the end cover, the slider is made of conductive material, and the slider is electrically connected to the stirring unit.

[0015] When sewage is gradually discharged from the water adding pipe into the treatment cylinder, the sewage level inside the treatment cylinder gradually rises, thereby pushing the float barrel to move upward along the slide barrel under the action of buoyancy. In the process of the float barrel moving upward, the push plate drives the rack to move upward. Under the transmission action of the gear, on the one hand, it drives the straight column to rotate, thereby driving the rotating plate to deflect, changing the flow of the dosing pipe, so that the larger the sewage volume, the higher the sewage level, the larger the opening of the dosing pipe channel, and the increase of the dosage. The dosage is adjusted in real time according to the change of the sewage level, avoiding the problem of insufficient dosage at high liquid level or excessive dosage at low liquid level. In the process of the push plate moving upward, it drives the conductive sheet to move upward. When the conductive sheet contacts the conductive block, the external controller controls the external water pump and the dosing box to stop, and stops the delivery of medicine and sewage. On the other hand, in the process of the rotation of the straight column, the steel rope is evenly wound, and the length of the steel rope gradually becomes shorter, thereby pulling the slider to move downward along the fixed cylinder.

[0016] Furthermore, the stirring unit includes a buffer spring, a column, an induction coil, a driving motor, a stirring rod and a stirring plate. One end of the buffer spring is fixedly connected to the fixed cylinder, and the other end is fixedly connected to the slider. The column is slidably connected to the slider. The column is provided with an induction coil. The end of the induction coil close to the horizontal ground is a current input end. The fixed end of the driving motor is fixedly installed on the outer surface of the processing cylinder. The output end of the driving motor is fixedly connected to the stirring rod. The stirring rod is rotatably connected to the processing cylinder. The stirring plate is fixedly connected to the stirring rod, and the driving motor is electrically connected to the slider.

[0017] As the slider stretches the buffer spring and moves downward, it slides downward along the column. At this time, the slider is always in contact with the induction coil, the effective number of turns of the induction coil gradually decreases, and the current gradually increases. The current is transmitted to the slider through the induction coil, and then the slider transmits the current to the drive motor, thereby increasing the speed of the drive motor. Under the transmission action of the stirring rod, the stirring plate is driven to rotate at a high speed, thereby achieving a large amount of sewage while increasing the stirring speed, and increasing the mixing uniformity of the flocculant and sewage.

[0018] Furthermore, the cleaning filter unit includes a filter plate, a slide, a counterweight, an electromagnet and a connecting rod. The filter plate is composed of an upper filter and a lower filter. The upper filter is provided with a slide. The upper filter is rotatably connected to the lower filter. A rotating motor is rotatably installed in the middle of the upper filter. The counterweight is slidably installed in the slide. The electromagnet is fixedly installed at the end of the slide. The connecting rod is fixedly installed on the lower filter. The connecting rod is rotatably connected to the processing cylinder.

[0019] Furthermore, the cleaning filter unit also includes a photoresistor group, a memory spring, an electric telescopic rod, an impact block and an elastic push switch. The photoresistor group is fixedly mounted on the end of the slide, one end of the memory spring is fixedly connected to the lower filter, and the other end is fixedly connected to the baffle, the fixed end of the electric telescopic rod is fixedly mounted on the inner surface of one end of the processing cylinder close to the horizontal base, the telescopic end of the electric telescopic rod is fixedly connected to the impact block, the elastic push switch is fixedly mounted on the upper filter, and the elastic push switch is electrically connected to the electric telescopic rod.

[0020] Furthermore, the material of the counterweight block is magnet.

[0021] Before the sewage enters the treatment cylinder through the water supply pipe, the rotating motor is started by the controller to drive the upper filter to deflect a certain angle so that the filter holes of the upper filter and the lower filter do not overlap, thereby providing a platform for the sewage and flocculant to fully react and settle impurities. When the height of the settled impurities exceeds the photoresistor group, the light intensity is the minimum at this time, and the resistance value of the photoresistor group becomes larger. When the controller detects that the photoresistor group prevents the rise to the preset interval value, it transmits current to the memory spring, thereby causing the spring to expand and contract, pulling the filter plate downward to deflect. At this time, the counterweight block slides downward along the slide under the action of gravity. When it contacts the elastic press switch, the current is turned on to control the corresponding electric telescopic rod to extend, driving the impact block to impact the bottom of the filter plate, so that the impurities accumulated on the filter plate are shaken off and discharged from the sewage outlet, realizing the self-cleaning function of the filter plate, thereby improving the sewage treatment rate. When the impurity cleaning is completed, the controller controls the electromagnet to present the opposite polarity to the counterweight block and cooperates with the memory spring to realize the reset of the counterweight block, so that the filter plate is reset to a horizontal state.

[0022] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention uses the characteristics of non-Newtonian fluid itself to solidify instantly and bulge upward when the sewage flow impacts the regulating soft ball and the sewage flow suddenly increases, thereby reducing the flow of sewage and avoiding excessive flow impact force, thereby preventing damage to the internal mechanism and reducing the service life. After the regulating soft ball solidifies and moves upward, it drives the straight plate to rotate around the round rod. When the straight plate rotates clockwise, the pressure plate at the other end is pressed and the telescopic plate contracts, thereby opening the channel of the diversion box, avoiding the increase of sewage liquid inside the treatment cylinder due to the increase of flow, and increasing the storage capacity of sewage.

[0023] 2. The present invention is that when sewage is gradually discharged from the water adding pipe into the treatment tube, the sewage level inside the treatment tube gradually rises, thereby pushing the float bucket to move upward along the slide tube under the action of buoyancy. In the process of the float bucket moving upward, the push plate drives the rack to move upward. Under the transmission action of the gear, on the one hand, it drives the straight column to rotate, thereby driving the rotating plate to deflect, changing the flow rate of the dosing tube, and realizing that the larger the sewage volume, the higher the sewage level, the larger the opening of the dosing tube channel, and the dosage is increased, and the dosage is adjusted in real time according to the change of sewage level, avoiding the problem of insufficient dosage at high liquid level or excessive dosage at low liquid level. In the process of the push plate moving upward, it drives the conductive sheet, and moves upward. When the conductive sheet moves upward, When the sheet contacts the conductive block, the external controller controls the external water pump and the dosing box to stop, and stops the addition of medicine and sewage. On the other hand, during the rotation of the straight column, the steel rope is evenly wound, and the length of the steel rope gradually becomes shorter, thereby pulling the slider to move downward along the fixed cylinder. The slider stretches the buffer spring and slides downward along the column during the downward movement. At this time, the slider is always in contact with the induction coil, and the effective number of turns of the induction coil gradually decreases, and the current gradually increases. The current is transmitted to the slider through the induction coil, and then the slider is transmitted to the drive motor to increase the speed of the drive motor. Under the transmission action of the stirring rod, the stirring plate is driven to rotate at a high speed, so as to achieve a large amount of sewage while increasing the stirring speed, and increase the mixing uniformity of the flocculant and sewage.

[0024] 3. The present invention starts the rotating motor through the controller before the sewage enters the treatment cylinder through the water supply pipe, drives the upper filter to deflect a certain angle, so that the filter holes of the upper filter and the lower filter do not overlap, thereby providing a platform for the sewage and the flocculant to fully react and settle the impurities. When the height of the settled impurities exceeds the photoresistor group, the light intensity is minimum at this time, and the resistance value of the photoresistor group becomes larger. When the controller detects that the photoresistor group prevents the rise to the preset interval value, it transmits current to the memory spring, so that the spring expands and contracts, and pulls the filter plate to deflect downward. At this time, the counterweight block slides downward along the slide table under the action of gravity. When it contacts the elastic pressing switch, the current is turned on to control the corresponding electric telescopic rod to extend, drive the impact block, and impact the bottom of the filter plate, so that the impurities accumulated on the filter plate are shaken off and discharged from the sewage outlet, realizing the self-cleaning function of the filter plate, thereby improving the sewage treatment rate. When the impurity cleaning is completed, the controller controls the electromagnet to cooperate with the memory spring under the action of the opposite polarity to the counterweight block to realize the reset of the counterweight block and reset the filter plate to a horizontal state.

The diversion box 28 is fixedly installed on the treatment cylinder 1, and a valve is provided at the fixed end of the telescopic plate 27.

[0032] like Figure 4 , Fig.14 As shown, the regulating soft ball 23 is filled with non-Newtonian fluid.

[0033] When the sewage flow impacts the regulating soft ball 23, the sewage flow suddenly increases. Due to the characteristics of the non-Newtonian fluid itself, it will solidify instantly and bulge upward due to the large impact force, thereby causing the center of gravity of the regulating soft ball 23 to move upward along the water supply pipe 13, reducing the flow of sewage, avoiding excessive flow impact force, causing damage to the internal mechanism, and reducing the service life. After the regulating soft ball 23 solidifies and moves upward, it drives the straight plate 24 to rotate around the round rod 25. While the straight plate 24 rotates clockwise, the pressure plate 26 at the other end is pressed, and the telescopic plate 27 contracts, thereby opening the channel of the diversion box 28, avoiding the increase in flow causing an increase in sewage liquid inside the treatment tube 1, and increasing the storage capacity of sewage.

[0036] When sewage is gradually discharged from the water supply pipe 13 into the treatment tube 1, the sewage level inside the treatment tube 1 gradually rises, thereby pushing the float 32 to move upward along the slide 31 under the action of buoyancy. In the process of the float 32 moving upward, the push plate 33 drives the rack 34 to move upward, and under the transmission action of the gear 35, on the one hand, the straight column 36 is driven to rotate, thereby driving the rotating plate 39 to deflect, changing the flow rate of the dosing tube 12, so that the larger the sewage volume, the higher the sewage level, the larger the opening of the dosing tube 12 channel, and the greater the injection rate.

On the other hand, during the rotation of the straight column 36, the steel rope 310 is evenly wound, and the length of the steel rope 310 gradually becomes shorter, thereby pulling the slider 311 to move downward along the fixed cylinder 312.

[0037] like Figure 3 , Fig.10 As shown, the stirring unit 4 includes a buffer spring 41, a column 42, an induction coil 43, a driving motor 44, a stirring rod 45 and a stirring plate 46. One end of the buffer spring 41 is fixedly connected to the fixed cylinder 312, and the other end is fixedly connected to the slider 311. The column 42 is slidably connected to the slider 311.

[0038] The slider 311 stretches the buffer spring 41 and slides downward along the column 42 during the downward movement. At this time, the slider 311 is always in contact with the induction coil 43, and the effective number of turns of the induction coil 43 gradually decreases, and the current gradually increases. The current is transmitted to the slider 311 through the induction coil 43, and then the slider 311 transmits the current to the drive motor 44, thereby increasing the speed of the drive motor 44. Under the transmission action of the stirring rod 45, the stirring plate 46 is driven to rotate at a high speed, thereby achieving a large amount of sewage while increasing the stirring speed, and increasing the mixing uniformity of the flocculant and sewage.

[0039] like Fig.11 , Fig.12As shown, the cleaning filter unit 5 includes a filter plate 51, a slide 52, a counterweight 53, an electromagnet 54 and a connecting rod 55. The filter plate 51 is composed of an upper filter screen and a lower filter screen. A slide 52 is provided on the upper filter screen.

[0041] like Fig.12 As shown, the material of the counterweight 53 is a magnet.

[0042] Before the sewage enters the treatment cylinder 1 through the water supply pipe 13, the controller starts the rotating motor to drive the upper filter to deflect a certain angle so that the filter holes of the upper filter and the lower filter do not overlap, thereby providing a platform for the sewage and the flocculant to fully react and settle the impurities. When the height of the settled impurities exceeds the photoresistor group 56, the light intensity is minimum at this time, and the resistance value of the photoresistor group 56 becomes larger. When the controller detects that the photoresistor group 56 prevents the resistance from rising to the preset interval value, it transmits current to the memory spring 57, thereby causing the spring to expand and contract, pulling the filter plate 51 downward to deflect, and the counterweight block 53 at this time is under the gravity When sliding downward along the slide table 52 under the action of, when contacting the elastic pressing switch 510, the conducting current controls the corresponding electric telescopic rod 58 to extend, driving the impact block 59 to impact the bottom of the filter plate 51, so that the impurities accumulated on the filter plate 51 are shaken off and discharged from the sewage outlet 14, realizing the self-cleaning function of the filter plate 51, thereby improving the sewage treatment rate. When the impurity cleaning is completed, the controller controls the electromagnet 54 to present the opposite polarity to the counterweight block 53 and cooperate with the memory spring 57 to realize the reset of the counterweight block 53, so that the filter plate 51 is reset to a horizontal state.

[0043] Working principle of the present invention: When the sewage flow impacts the regulating soft ball 23, the sewage flow suddenly increases. Due to the characteristics of the non-Newtonian fluid itself, it will solidify instantly and bulge upward due to the large impact force, thereby causing the center of gravity of the regulating soft ball 23 to move upward along the water supply pipe 13, reducing the flow of sewage, avoiding excessive flow impact force, causing damage to the internal mechanism, and reducing the service life. After the regulating soft ball 23 solidifies and moves upward, it drives the straight plate 24 to rotate around the round rod 25. While the straight plate 24 rotates clockwise, the pressure plate 26 at the other end is pressed, and the telescopic plate 27 contracts, thereby opening the channel of the diversion box 28, avoiding the increase in flow causing an increase in sewage liquid inside the treatment tube 1, and increasing the storage capacity of sewage.

[0044] As sewage is gradually discharged from the water filling pipe 13 into the treatment tube 1, the sewage level inside the treatment tube 1 gradually rises, thereby pushing the float 32 to move upward along the slide 31 under the action of buoyancy. In the process of the float 32 moving upward, the push plate 33 is pushed to drive the rack 34 to move upward. Under the transmission action of the gear 35, on the one hand, the straight column 36 is driven to rotate, thereby driving the rotating plate 39 to deflect, changing the flow rate of the dosing tube 12, so that the larger the sewage volume, the higher the sewage level, the larger the opening of the dosing tube 12 channel, and the increase of the dosage. The dosage is adjusted in real time according to the change of the sewage level, avoiding the problem of insufficient dosage at a high liquid level or excessive dosage at a low liquid level. In the process of the push plate 33 moving upward, it drives the conductive sheet 37 to move upward. When the conductive sheet 37 contacts the conductive block 38, the outer The external controller controls the external water pump and the dosing box to stop, and stops the addition of medicine and sewage. On the other hand, during the rotation of the straight column 36, the steel rope 310 is evenly wound, and the length of the steel rope 310 gradually becomes shorter, thereby pulling the slider 311 to move downward along the fixed cylinder 312. The slider 311 stretches the buffer spring 41 and slides downward along the column 42 during the downward movement. At this time, the slider 311 is always in contact with the induction coil 43, and the effective number of turns of the induction coil 43 gradually decreases, and the current gradually increases. The current is transmitted to the slider 311 through the induction coil 43, and then the slider 311 is transmitted to the drive motor 44, thereby increasing the speed of the drive motor 44. Under the transmission action of the stirring rod 45, the stirring plate 46 is driven to rotate at a high speed, so as to achieve a large amount of sewage while increasing the stirring speed, thereby increasing the mixing uniformity of the flocculant and sewage.

[0045] Before the sewage enters the treatment cylinder 1 through the water supply pipe 13, the controller starts the rotating motor to drive the upper filter to deflect a certain angle so that the filter holes of the upper filter and the lower filter do not overlap, thereby providing a platform for the sewage and the flocculant to fully react and settle the impurities. When the height of the settled impurities exceeds the photoresistor group 56, the light intensity is minimum at this time, and the resistance value of the photoresistor group 56 becomes larger. When the controller detects that the photoresistor group 56 prevents the resistance from rising to the preset interval value, it transmits current to the memory spring 57, thereby causing the spring to expand and contract, pulling the filter plate 51 downward to deflect, and the counterweight block 53 at this time is under the gravity When sliding downward along the slide table 52 under the action of, when contacting the elastic pressing switch 510, the conducting current controls the corresponding electric telescopic rod 58 to extend, driving the impact block 59 to impact the bottom of the filter plate 51, so that the impurities accumulated on the filter plate 51 are shaken off and discharged from the sewage outlet 14, realizing the self-cleaning function of the filter plate 51, thereby improving the sewage treatment rate. When the impurity cleaning is completed, the controller controls the electromagnet 54 to present the opposite polarity to the counterweight block 53 and cooperate with the memory spring 57 to realize the reset of the counterweight block 53, so that the filter plate 51 is reset to a horizontal state.
