Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a sewage treatment slag discharging device and a treatment method. Background Technique

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or for reuse. Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and is also increasingly entering the daily lives of ordinary people. A grille is the most important auxiliary equipment in a sewage pumping station. Generally, a grille consists of a group of parallel grid bars and is located at the inlet of the sump of the pumping station.

[0003] For example, the patent document with the publication number CN211570275U discloses a grille tank for sewage treatment, which includes a grille tank, a sedimentation tank, and a purification tank. An inlet is opened at the top of the inner cavity of the grille tank. First fixing blocks are fixedly connected to the tops of both sides of the inner cavity of the grille tank. A coarse grille is arranged between the two first fixing blocks. The inner cavity of the first fixing block is threadedly connected with a first bolt, and the first bolt penetrates through the first fixing block and extends into the inner cavity of the coarse grille. Second fixing blocks are fixedly connected to the tops of both sides of the inner cavity of the grille tank. Through the cooperation of the grille tank, the sedimentation tank, the purification tank, the first fixing blocks, the coarse grille, the first bolt, the second fixing blocks, the fine grille, and the second bolt, the present utility model has the advantage of good sewage treatment effect, and solves the problems that the sewage treatment efficiency of the existing grille tank for sewage treatment is slow, the treatment effect is not ideal enough, thereby reducing the working efficiency and the sewage treatment quality.

[0004] However, the existing technology still has the following deficiencies in the actual application process:

[0005] The treatment effect on sewage is poor, the efficiency is low, and the degree of automation is not high enough, resulting in an unsatisfactory overall working effect. Because in the above patent document, when sewage enters the grille tank, a cutting mechanism for the sludge in the sewage is not provided, and the situation of sludge clogging the coarse grille may occur, resulting in a poor sewage filtration and screening effect. Moreover, an efficient stirring mechanism for sewage, flocculant, and medicament is not provided in the sedimentation tank, so the sedimentation generation speed is relatively slow.

[0006] At the same time, when the concentration of the sewage entering the grille tank increases, when the sewage filtered by the coarse grille and the fine grille enters the sedimentation tank, stronger stirring is required to make the sewage react with the flocculant added to the sedimentation tank to ensure sufficient reaction, and the coarse grille is easily clogged by agglomerated sediment, thereby reducing the filtration efficiency. Summary of the Invention

[0020] A treatment method of a sewage treatment and slag discharging device includes the following steps:

[0021] S1. Add sewage to the grille tank through the pipeline at the upper end of the grille tank, and then start the motor. The motor drives the sprocket to rotate, so that under the cooperation of the first connecting rod and the second connecting rod, the L-shaped rod forms a left-right reciprocating movement. When the L-shaped rod moves left and right, under the action of the rack, the first gear and the eccentric block rotate. The eccentric block continuously presses the reciprocating plate, so that the sliding column slides and is restored under the action of the spring. That is, while the reciprocating plate moves left and right, it also vibrates up and down. While the blade moves left and right, it also cuts the sludge, so that the agglomerated sludge can be crushed, and the sewage can be filtered and screened through the coarse grille and the fine grille;

[0022] S2, start the first water pump to pump the sewage into the sedimentation tank, use the aerator to perform aeration treatment, then add flocculant to the sedimentation tank, use the medicine pump to pump the liquid medicine in the medicine box into the sedimentation tank, and under the cooperation of the first bevel gear and the second bevel gear, the stirring shaft rotates, and the stirring blades stir the sewage. At the same time, under the action of the ring gear, the second gear rotates, and under the cooperation of the third bevel gear and the fourth bevel gear, the electric push rod and the third connecting rod drive the flipping rod to swing back and forth, so that the flipping plate can be made to revolve while swinging, so that the sewage is flipped more violently until the sewage and the liquid medicine react completely;

[0023] During S3, the electric telescopic rod is started to rotate the solar panel and adjust the tilt angle of the solar panel, so that the solar panel can better absorb sunlight and provide power for the aerator, which is convenient for the use of the aerator;

[0024] S4. After the sewage reacts with the liquid medicine and precipitates, the sewage after the reaction and precipitation is pumped into the inner cavity of the purification tank through the second water pump. The sewage is purified by the filter net, the activated carbon adsorption net and the PP cotton filter element net in turn, and finally discharged through the drain pipe.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. In the present invention, sewage is added to the grid pool through a pipe at the upper end of the grid pool, and then the motor is started to make the L-shaped rod reciprocate left and right. Under the action of the rack, the first gear and the eccentric block rotate, and the eccentric block continuously squeezes the reciprocating plate to make the sliding column slide and restore under the action of the spring, so that the reciprocating plate can be moved left and right while vibrating up and down, and the blade can be moved left and right while cutting the sludge, so that the agglomerated sludge can be crushed. Under the cooperation of the first bevel gear and the second bevel gear, the stirring shaft rotates, and the stirring blade stirs the sewage. At the same time, under the action of the ring gear, the electric push rod and the third connecting rod drive the flipping rod to swing back and forth, so that the flipping plate can be revolved while swinging, so that the sewage is flipped more violently until the precipitation is completely produced, thereby having a cutting effect on the sludge in the sewage before the precipitation reaction, improving the filtering and screening effect of the coarse grid and the fine grid, and having a uniform mixing effect on the sewage, flocculant and liquid medicine, accelerating the speed of precipitation.

[0027] 2. In the present invention, a person starts the electric telescopic rod to rotate the solar panel and adjust the tilt angle of the solar panel, so that the solar panel can better absorb sunlight, thereby providing electrical energy to the aerator, making it easier to use the aerator.

[0028] 3. In the present invention, by setting a pressure sensor and an electric push rod, when the amount of sundries such as caked sediment in the sewage entering the grille tank increases, that is, the concentration of the sewage increases, the resistance to the up and down movement of the blade increases. The pressure sensor is used to detect the resistance to the up and down movement of the blade, and indirectly obtain the concentration of the sewage entering the grille tank. Then, according to the detection value of the pressure sensor, the length of the electric push rod is adjusted correspondingly, so as to adjust the up and down swing amplitude of the turning plate, thereby adjusting the stirring effect in the sedimentation tank, making the reaction between the sewage and the liquid medicine such as the flocculant more sufficient, and improving the convenience and effect of the equipment use.

At the same time, under the action of the ring gear 36, the second gear 37 rotates, and under the cooperation of the third bevel gear 39 and the fourth bevel gear 40, the electric push rod 42 and the third connecting rod 41 drive the flipping rod 43 to swing back and forth, that is, the flipping plate 44 is swinging while revolving, so that the sewage is flipped more violently until the precipitation is completely produced, thereby having a cutting effect on the sludge in the sewage before the precipitation reaction, improving the filtering and screening effect of the coarse grid 2 and the fine grid 3, and having a uniform mixing effect on the sewage, flocculant, and liquid medicine, accelerating the speed of precipitation, and having a high overall sewage treatment efficiency and a relatively ideal treatment effect.The whole process involves less manual operation, has a high degree of automation, and is convenient and labor-saving.

[0045] In the middle of the left side of the upper end surface of the sedimentation tank 45, a solar panel 18 is rotatably connected through a pin shaft. In the middle of the right side of the upper end surface of the sedimentation tank 45, an electric telescopic rod 14 is fixedly connected. The piston end of the electric telescopic rod 14 is embedded in the solar panel 18 through a pin shaft and is slidably connected thereto. The solar panel 18 is electrically connected to the aerator 47 through a storage battery. By starting the electric telescopic rod 14 by personnel, the solar panel 18 can be rotated to adjust the inclination angle of the solar panel 18, so that the solar panel 18 can better absorb sunlight, thereby providing electrical energy for the aerator 47, and further facilitating the use of the aerator 47.

[0046] In the middle of the lower right side of the sedimentation tank 45, a second water pump 28 is provided. The water outlet end of the second water pump 28 is provided with a purification tank 22 through a third connecting pipe 29. The inner cavity wall of the purification tank 22 is respectively provided with a filter screen 23, an activated carbon adsorption net 24 and a PP cotton filter element net 25. In the middle of the lower right side of the purification tank 22, a drain pipe 26 is provided, and the drain pipe 26 is located below the PP cotton filter element net 25.

[0047] When the present invention is in use, sewage is added to the grille tank 1 through the pipeline at the upper end of the grille tank 1, and then the motor 35 is started. The motor 35 drives the sprocket 34 to rotate, so that under the cooperation of the first connecting rod 17 and the second connecting rod 27, the L-shaped rod 10 forms a reciprocating movement left and right. When the L-shaped rod 10 moves left and right, under the action of the rack 4, the first gear 5 and the eccentric block 12 rotate. The eccentric block 12 continuously squeezes the reciprocating plate 8, causing the sliding column 9 to slide and recover under the action of the spring 11. Thus, while the reciprocating plate 8 moves left and right, it also vibrates up and down. While the blade 7 moves left and right, it also cuts the sludge, so that the agglomerated sludge can be crushed. The sewage can be filtered and screened through the coarse grille 2 and the fine grille 3. Then, the first water pump 13 is started to pump the sewage into the sedimentation tank 45 again, and aeration treatment is carried out by the aerator 47. Then, a flocculant is added to the sedimentation tank 45, and the liquid medicine in the medicine tank 21 is pumped into the sedimentation tank 45 by the medicine pump 20. Under the cooperation of the first bevel gear 31 and the second bevel gear 32, the stirring shaft 30 rotates, and the stirring blades 38 stir the sewage. At the same time, under the action of the gear ring 36, the second gear 37 rotates. Under the cooperation of the third bevel gear 39 and the fourth bevel gear 40, the electric push rod 42 and the third connecting rod 41 drive the turning rod 43 to swing reciprocally. Thus, while the turning plate 44 revolves, it also swings, making the sewage turn more violently until the precipitation is completely generated. Therefore, it can play a role in cutting the sludge in the sewage before the precipitation reaction, improving the filtering and screening effect of the coarse grille 2 and the fine grille 3. Moreover, it can play a role in uniformly mixing the sewage, the flocculant, and the liquid medicine, accelerating the speed of precipitation generation, having a high overall treatment efficiency for the sewage, and an ideal treatment effect. Furthermore, the whole process has less manual participation, high automation, is convenient and labor-saving. The operator starts the electric telescopic rod 14 to rotate the solar panel 18 and adjust the inclination angle of the solar panel 18, so that the solar panel 18 can better absorb sunlight, thereby providing electric energy for the aerator 47, and further facilitating the use of the aerator 47. After the precipitation is completed, the precipitated sewage is pumped into the inner cavity of the purification tank 22 by the second water pump 28. The sewage is purified successively through the filter screen 23, the activated carbon adsorption net 24, and the PP cotton filter element net 25, and finally the sewage is discharged through the drain pipe 26. Embodiment 2

[0048] Based on the sewage treatment and slag discharge device of the above-mentioned Embodiment 1, although the device has a high degree of automation, is convenient and labor-saving, when the concentration of the sewage entering the grille tank 1 increases during the use of the device, when the sewage filtered by the coarse grille 2 and the fine grille 3 enters the sedimentation tank 45, stronger stirring is required to make the sewage react with the flocculant added to the sedimentation tank 45 to ensure sufficient reaction. And the coarse grille 2 is easily blocked by agglomerated sediment and sand, thus reducing the filtration efficiency. For this reason, we propose the following technical solutions:

[0049] Please refer to Figures 1 - 9 , a pressure sensor is provided at the top end of the reciprocating plate 8 at the position of the eccentric block 12, and an electric push rod is provided inside the electric push rod 42. The pressure sensor is used to detect the pressure between the eccentric block 12 and the reciprocating plate 8, and thus reflect the force when the blade 7 cuts the caked sediment. The electric push rod can drive the electric push rod 42 on the side away from the axis of the fourth bevel gear 40 to extend or shorten.

[0050] When the present invention is in use, sewage is added to the grille tank 1 through the pipeline at the upper end of the grille tank 1, and then the motor 35 is started. The motor 35 drives the sprocket 34 to rotate through the chain 33, so that under the cooperation of the first connecting rod 17 and the second connecting rod 27, the L-shaped rod 10 moves left and right reciprocally. When the L-shaped rod 10 moves left and right, under the action of the rack 4, the first gear 5 rotates. The rotation of the first gear 5 drives the rotation of the eccentric block 12. The rotation of the eccentric block 12, with the assistance of the spring 11, makes the reciprocating plate 8 move up and down. The up and down movement of the reciprocating plate 8 drives the up and down movement of the blade 7. When the blade 7 moves up and down, the blade 7 cuts and beats the caked sediment in the sewage to make it loose. And with the up and down movement of the blade 7 and the left and right movement of the L-shaped rod 10, the up and down moving blade 7 will also beat the coarse grille 2, causing the coarse grille 2 to vibrate, so as to assist in cleaning the impurities blocked in the coarse grille 2. At the same time, when the amount of caked sediment in the sewage increases, the resistance received by the up and down movement of the blade 7 will also increase, and at this time, the detection value of the pressure sensor will also increase.

[0051] After the motor 35 is started, it will also drive the rotation of the first bevel gear 31. The rotation of the first bevel gear 31 drives the rotation of the second bevel gear 32 through meshing transmission. The rotation of the second bevel gear 32 drives the rotation of the stirring shaft 30. The rotation of the stirring shaft 30 drives the rotation of the stirring blades 38. The rotation of the stirring blades 38 makes the sewage in the sedimentation tank 45 react fully with the flocculant.

[0052] The rotation of the stirring shaft 30 drives the rotation of the rotating plate 46 at the same time. The rotation of the rotating plate 46 makes the second gear 37 and the toothed ring 36 engage in transmission, so that the second gear 37 rotates. The rotation of the second gear 37 drives the rotation of the third bevel gear 39 through the pin shaft. The rotation of the third bevel gear 39 drives the rotation of the fourth bevel gear 40 through meshing transmission. The rotation of the fourth bevel gear 40, with the assistance of the third connecting rod 41 and the electric push rod 42, makes both ends of the turning rod 43 swing up and down. The up and down swing of both ends of the turning rod 43 drives the up and down movement of the turning plate 44. With the rotation of the rotating plate 46 and the up and down movement of the turning plate 44, the reaction between the sewage and the flocculant in the sedimentation tank 45 becomes more sufficient.

[0053] When the detected value of the pressure sensor increases, it indicates that there is an increase in impurities such as caked sediment in the sewage entering the grille tank 1, that is, the concentration of the sewage increases. At this time, if the original stirring efficiency is adopted in the sedimentation tank 45, it will take a longer time for the sewage to fully react with the liquid medicine such as the flocculant. In order to improve the efficiency of sewage reaction, when the detected value of the pressure sensor increases, the electric push rod 42 is started to increase the length of the electric push rod 42. After the length of the electric push rod 42 increases, with the rotation of the fourth bevel gear 40, the rotation of the fourth bevel gear 40, with the assistance of the third connecting rod 41 and the electric push rod 42, makes both ends of the turning rod 43 swing up and down. The up and down swing of both ends of the turning rod 43 drives the up and down movement of the turning plate 44, increasing the distance of the up and down movement of the turning plate 44, thereby enhancing the swinging effect of the turning plate 44, strengthening the stirring effect on the sewage in the sedimentation tank 45, strengthening the reaction effect between the sewage and the liquid medicine such as the flocculant, and improving the convenience of equipment use.

[0054] In the present invention, by setting a pressure sensor and an electric push rod, when there is an increase in impurities such as caked sediment in the sewage entering the grille tank 1, that is, the concentration of the sewage increases, the resistance received by the up and down movement of the blade 7 increases. The pressure sensor detects the resistance received by the up and down movement of the blade 7, indirectly obtaining the concentration of the sewage entering the grille tank 1. Then, according to the detected value of the pressure sensor, the length of the electric push rod 42 is correspondingly adjusted, thereby adjusting the amplitude of the up and down swing of the turning plate 44, thereby adjusting the stirring effect in the sedimentation tank 45, making the reaction between the sewage and the liquid medicine such as the flocculant more sufficient, and improving the convenience and effect of equipment use. Embodiment 3

[0055] A sewage treatment method using the sewage treatment and slag discharging device of the above embodiment, including the following specific steps:

[0056] S1. Add the sewage to the grille tank 1 through the pipeline at the upper end of the grille tank 1, then start the motor 35. The motor 35 drives the sprocket 34 to rotate, and under the cooperation of the first connecting rod 17 and the second connecting rod 27, the L-shaped rod 10 makes a reciprocating movement left and right. When the L-shaped rod 10 moves left and right, under the action of the rack 4, the first gear 5 and the eccentric block 12 rotate. The eccentric block 12 continuously squeezes the reciprocating plate 8, causing the sliding column 9 to slide and recover under the action of the spring 11. That is, while the reciprocating plate 8 moves left and right, it also vibrates up and down. While the blade 7 moves left and right, it also cuts the sludge, pulverizing the caked sludge, and enabling the sewage to be filtered and screened through the coarse grille 2 and the fine grille 3.

[0057] S2. Then start the first water pump 13 to pump the sewage back into the sedimentation tank 45, and conduct aeration treatment using the aerator 47. Then add a flocculant to the sedimentation tank 45, use the chemical pump 20 to pump the liquid medicine inside the medicine tank 21 into the sedimentation tank 45, and under the cooperation of the first bevel gear 31 and the second bevel gear 32, make the stirring shaft 30 rotate, and the stirring blades 38 stir the sewage. At the same time, under the action of the gear ring 36, make the second gear 37 rotate. Under the cooperation of the third bevel gear 39 and the fourth bevel gear 40, make the electric push rod 42 and the third connecting rod 41 drive the turning rod 43 to swing reciprocally, so that while the turning plate 44 rotates around the center, it also swings, making the sewage turn more violently until complete precipitation occurs.

[0058] S3. During this period, the operator starts the electric telescopic rod 14 to rotate the solar panel 18 and adjust the tilt angle of the solar panel 18, so that the solar panel 18 can better absorb sunlight and provide electrical energy for the aerator 47, facilitating the use of the aerator 47.

[0059] S4. After the precipitation is completed, pump the precipitated sewage into the inner cavity of the purification tank 22 through the second water pump 28. The sewage is purified successively through the filter screen 23, the activated carbon adsorption screen 24, and the PP cotton filter element screen 25, and finally discharged through the drain pipe 26.

[0060] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
