Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment, and particularly relates to a self-maintaining integrated sewage treatment device and a sewage treatment method thereof. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. 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.

[0003] An existing integrated sewage treatment device with the publication number CN111925035B includes a conveyor belt. One end of the conveyor belt is fixed to the inner wall of the grid box, and the other end of the conveyor belt is fixed to the inner wall of the material removal platform. One end of the conveyor belt is connected to the output end of the first motor, and the bottom of the first motor is fixed to the material removal platform by screws. In this preferred embodiment, it is convenient to remove larger foreign objects in the sewage through the conveyor belt assembly. There are water flow holes on the conveyor belt, and there are multiple material removal heads on the conveyor belt. Larger foreign objects in the sewage are removed through the material removal heads, and the larger foreign objects in the sewage are continuously moved into the collection box through the cooperation of the conveyor belt and the material removal heads. It is convenient to collect foreign objects through the collection box, and the collection box is installed in a sliding manner for easy disassembly and cleaning.

[0004] In the above solution, when treating sewage, the sewage is first pretreated through the material removal heads to filter and remove the larger pollutants in the sewage. However, in this solution, when the sewage is pretreated through the material removal heads, only the pollutants with larger volumes can be filtered and transferred, but some pollutants with smaller volumes cannot be filtered in time, and some pollutants with larger masses are prone to accumulate at the bottom of the box body. After long-term accumulation, it is easy to cause jamming at one end of the conveyor belt, affecting the operation of the conveyor belt. Summary of the Invention

[0005] The purpose of the present invention is to provide a self-maintaining integrated sewage treatment device and a sewage treatment method thereof, aiming to solve the technical problem that pollutants are prone to accumulate and are not easily discharged during sewage pretreatment in the prior art.

[0006] The present invention is realized as follows. A self-maintaining integrated sewage treatment device includes a pretreatment tank, a sedimentation tank, and a collection tank. The pretreatment tank is communicated with the sedimentation tank. A first driving roller is rotatably connected in the collection tank. The first driving roller is connected to a motor. A second driving roller is arranged in the pretreatment tank. A conveyor belt is arranged between the first driving roller and the second driving roller. An adjusting assembly is arranged between the second driving roller and the inner wall of the pretreatment tank, and the adjusting assembly can drive the second driving roller to move;

[0007] There are multiple rows of blocking rods arranged at intervals on the conveyor belt, and a drainage plate is arranged on one side of each row of blocking rods. The drainage plate is rotationally connected to the conveyor belt through an elastic torsion spring. The drainage plate is rotationally connected to a filter plate, one end of the filter plate is slidably connected to the conveyor belt, and a filter mesh opening is arranged on the conveyor belt between the filter plate and the drainage plate;

[0008] A guiding component is arranged on one side of the conveyor belt, and the guiding component can guide the sewage towards the conveyor belt;

[0009] A control system. When the sewage flow on the guiding component is large or pollutants accumulate, the control system can control the adjusting component, the guiding component, and the motor to increase the filtering and conveying efficiency of the conveyor belt for pollutants.

[0010] Further technical solution: The adjusting component includes an arc-shaped guide rail, a sliding seat, and an electric driving part;

[0011] The arc-shaped guide rail is arranged on the inner wall of the pretreatment tank. The arc-shaped guide rail takes the center of the first driving roller as the center of the circle. The sliding seat is slidably connected in the arc-shaped guide rail. The fixed end of the electric driving part is fixedly connected to the inner wall of the pretreatment tank, and the telescopic end of the electric driving part is rotationally connected to the sliding seat. The second driving roller is rotationally connected to the sliding seat.

[0012] Further technical solution: The guiding component includes a diversion plate and an electric support seat. One end of the diversion plate is rotationally connected to the inner wall of the pretreatment tank. The fixed end of the electric support seat is fixedly connected to the inner wall of the pretreatment tank, and the telescopic end of the electric support seat abuts against the diversion plate.

[0013] Further technical solution: A cam is rotationally connected to the inner wall of the collection box, and a belt transmission pair is arranged between the cam and the first driving roller. Further technical solution: The aperture of the filter mesh opening is smaller than the aperture of the filter plate.

[0014] Further technical solution: The control system includes:

[0015] A monitoring module for monitoring and obtaining the external pressure information received by the diversion plate;

[0016] A processing module for receiving the pressure information at the current moment in the monitoring module and forming a judgment information;

[0017] A control module for receiving the judgment information and controlling the adjusting component, the guiding component, and the motor according to the judgment information.

[0018] Further technical solution: The monitoring module is a gravity sensor, and the gravity sensor is arranged at the telescopic end of the electric support seat.

[0019] A sewage treatment method is applied to the self-maintaining integrated sewage treatment equipment described above and includes the following steps:

[0020] Step S1: When sewage enters the pretreatment tank, the guiding component guides the sewage to the conveyor belt. At this time, the sewage passes through the filter plate and the filter mesh opening in sequence, and then enters the collection tank;

[0021] Step S2: When the sewage contacts the conveyor belt under the action of water flow, the pollutants in the sewage accumulate near the conveyor belt under the push of the water flow. The motor drives the first driving roller to rotate, and the first driving roller and the second driving roller drive the conveyor belt to move. Driven by the conveyor belt, the blocking rod intercepts the pollutants with larger volume and pushes them into the collection tank. At this time, the remaining pollutants with smaller volume accumulate towards the filter plate. The filter plate and the filter mesh opening filter and convey the pollutants in the sewage. Under the combined action of the blocking rod, the filter plate and the filter mesh opening, the pollutants with different volumes in the sewage are fully filtered, pushed and collected;

[0022] Step S3: When the sewage discharge continues to increase or the pollutants in the sewage continue to increase, the regulation system can control the adjustment component, the guiding component and the motor to further increase the filtering and conveying efficiency of the conveyor belt for pollutants.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. A self-maintaining integrated sewage treatment equipment. Driven by the conveyor belt, the blocking rod intercepts the pollutants with larger volume and pushes them into the collection tank. At this time, the remaining pollutants with smaller volume accumulate towards the filter plate. The filter plate and the filter mesh opening filter and convey the pollutants in the sewage. Under the combined action of the blocking rod, the filter plate and the filter mesh opening, the pollutants with different volumes in the sewage are fully filtered, pushed and collected;

[0025] 2. A self-maintaining integrated sewage treatment equipment. When the weight of the pollutants accumulated on the filter plate increases, the filter plate rotates under the force. The pollutants on the filter plate slide down along the filter plate to prevent the filter plate from being completely blocked; Driven by the filter plate, the included angle between the drainage plate and the conveyor belt increases, thereby improving the drainage effect of the drainage plate and increasing the flow-through efficiency of the filter mesh opening;

[0026] 3. A self-maintaining integrated sewage treatment equipment. When the sewage discharge continues to increase or the pollutants in the sewage continue to increase, the processing module receives the pressure information at the current moment from the gravity sensor and forms a judgment information. The control module receives the judgment information and controls the electric drive member, the electric support seat and the motor according to the judgment information to prevent pollutants from accumulating.

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0036] As Figures 1 - 6 shown, a self-maintaining integrated sewage treatment device provided by the present invention includes a pretreatment tank 1, a sedimentation tank 2 and a collection tank 3. The pretreatment tank 1 is communicated with the sedimentation tank 2. A first driving roller 4 is rotatably connected in the collection tank 3. The first driving roller 4 is connected to a motor 13. A second driving roller 5 is arranged in the pretreatment tank 1. A conveyor belt 7 is arranged between the first driving roller 4 and the second driving roller 5. An adjusting component 6 is arranged between the second driving roller 5 and the inner wall of the pretreatment tank 1. The adjusting component 6 can drive the second driving roller 5 to move;

[0037] A plurality of rows of retaining bars 10 are arranged at intervals on the conveyor belt 7, and a drainage plate 11 is arranged on one side of each row of retaining bars 10. The drainage plate 11 is rotatably connected to the conveyor belt 7 through an elastic torsion spring. The drainage plate 11 is rotatably connected to a filter plate 12. One end of the filter plate 12 is slidably connected to the conveyor belt 7. A filter screen opening 14 is arranged on the conveyor belt 7 between the filter plate 12 and the drainage plate 11;

[0038] A guiding assembly 8 is arranged on one side of the conveyor belt 7. The guiding assembly 8 can guide the sewage towards the conveyor belt 7;

[0039] A control system. When the sewage flow rate on the guiding assembly 8 is large or pollutants accumulate, the control system can control the adjusting assembly 6, the guiding assembly 8 and the motor 13 to increase the filtering and conveying efficiency of the conveyor belt 7 for pollutants.

[0040] A sewage treatment method is applied to the self-maintaining sewage treatment integrated equipment in the above embodiment, and includes the following steps:

[0041] Step S1: When the sewage enters the pretreatment tank 1, the guiding assembly 8 guides the sewage to the conveyor belt 7. At this time, the sewage passes through the filter plate 12 and the filter screen opening 14 in sequence, and then enters the collection tank 3;

[0042] Step S2: When the sewage contacts the conveyor belt 7 under the action of the water flow, the pollutants in the sewage accumulate near the conveyor belt 7 under the push of the water flow. The motor 13 drives the first driving roller 4 to rotate. The first driving roller 4 and the second driving roller 5 drive the conveyor belt 7 to move. Driven by the conveyor belt 7, the retaining bars 10 intercept the larger-volume pollutants and push them into the collection tank 3. At this time, the remaining smaller-volume pollutants accumulate towards the filter plate 12. The filter plate 12 and the filter screen opening 14 filter and convey the pollutants in the sewage. Under the combined action of the retaining bars 10, the filter plate 12 and the filter screen opening 14, the pollutants of different volumes in the sewage are fully filtered, pushed and collected;

[0043] The weight of the pollutants accumulated at the filter plate 12 increases. At this time, the filter plate 12 rotates under the force, and the pollutants on the filter plate 12 slide down along the filter plate 12 to prevent the filter plate 12 from being completely blocked; Driven by the filter plate 12, the included angle between the drainage plate 11 and the conveyor belt 7 increases, thereby improving the drainage effect of the drainage plate 11 and increasing the flow rate of the filter screen opening 14;

[0044] Step S3: When the sewage discharge continues to increase or the pollutants in the sewage continue to increase, the control system can control the adjusting assembly 6, the guiding assembly 8 and the motor 13 to further increase the filtering and conveying efficiency of the conveyor belt 7 for pollutants.

[0045] As Figure 3As shown, as a preferred embodiment, the adjustment assembly 6 includes an arc-shaped guide rail 61, a sliding seat 62, and an electric driving member 63;

[0046] The arc-shaped guide rail 61 is arranged on the inner wall of the pretreatment tank 1. The arc-shaped guide rail 61 takes the center of the first driving roller 4 as the center of the circle. The sliding seat 62 is slidably connected in the arc-shaped guide rail 61. The fixed end of the electric driving member 63 is fixedly connected to the inner wall of the pretreatment tank 1. The telescopic end of the electric driving member 63 is rotatably connected to the sliding seat 62. The second driving roller 5 is rotatably connected to the sliding seat 62.

[0047] In this embodiment, when the electric driving member 63 is started, the telescopic end of the electric driving member 63 moves. The electric driving member 63 pulls the sliding seat 62, and the sliding seat 62 slides along the arc-shaped guide rail 61. The sliding seat 62 drives the second driving roller 5 to move synchronously. By moving the position of the second driving roller 5, the horizontal inclination angle of the conveyor belt 7 is adjusted, so as to adjust the load-bearing capacity of the conveyor belt 7 for pollutants.

[0048] As Figure 2 shown, as a preferred embodiment, the guiding assembly 8 includes a diversion plate 81 and an electric support seat 82. One end of the diversion plate 81 is rotatably connected to the inner wall of the pretreatment tank 1. The fixed end of the electric support seat 82 is fixedly connected to the inner wall of the pretreatment tank 1, and the telescopic end of the electric support seat 82 abuts against the diversion plate 81.

[0049] The diversion plate 81 diverts the sewage. At the same time, the electric support seat 82 supports the diversion plate 81. When the electric support seat 82 expands and contracts, the inclination angle of the diversion plate 81 changes. Increasing the horizontal inclination angle of the diversion plate 81 can prevent pollutants from accumulating on the diversion plate 81.

[0050] As Figure 1 and Figure 4 shown, as a preferred embodiment, a cam 15 is rotatably connected to the inner wall of the collection box 3. A belt transmission pair 9 is arranged between the cam 15 and the first driving roller 4. When the first driving roller 4 rotates, the first driving roller 4 drives the cam 15 to rotate through the belt transmission pair 9. The cam 15 intermittently pushes the conveyor belt 7, thereby driving the conveyor belt 7 to vibrate, and further vibrating and collecting the pollutants on the conveyor belt 7.

[0051] As a preferred embodiment, the aperture of the filter mesh opening 14 is smaller than the aperture of the filter plate 12.

[0052] As Figure 6 shown, as a preferred embodiment, the control system includes:

[0053] A monitoring module, which is used to monitor and obtain the external pressure information received by the diversion plate 81;

[0054] A processing module, configured to receive the pressure information at the current moment in the monitoring module and form judgment information;

[0055] A control module, configured to receive the judgment information and control the regulating component 6, the guiding component 8, and the motor 13 according to the judgment information.

[0056] As a preferred embodiment, the monitoring module is a gravity sensor, and the gravity sensor is arranged at the telescopic end of the electric support base 82.

[0057] Working principle:

[0058] When sewage enters the pretreatment tank 1, the guide plate 81 guides the sewage to the conveyor belt 7. The electric support base 82 supports the guide plate 81, and the gravity sensor senses the sewage load on the guide plate 81. At this time, the sewage passes through the filter plate 12 and the filter mesh opening 14 in sequence, and then enters the collection tank 3;

[0059] When the sewage contacts the conveyor belt 7 under the action of water flow, the pollutants in the sewage accumulate near the conveyor belt 7 under the push of the water flow. The motor 13 drives the first driving roller 4 to rotate, and the first driving roller 4 and the second driving roller 5 drive the conveyor belt 7 to move. Driven by the conveyor belt 7, the blocking rod 10 intercepts the pollutants with larger volume and pushes them into the collection tank 3. At this time, the remaining pollutants with smaller volume accumulate towards the filter plate 12. The filter plate 12 and the filter mesh opening 14 filter and convey the pollutants in the sewage. Under the combined action of the blocking rod 10, the filter plate 12, and the filter mesh opening 14, the pollutants with different volumes in the sewage are fully filtered, pushed, and collected;

[0060] The weight of the pollutants accumulated at the filter plate 12 increases. At this time, the filter plate 12 rotates under the force, and the pollutants on the filter plate 12 slide down along the filter plate 12 to prevent the filter plate 12 from being completely blocked; Driven by the filter plate 12, the included angle between the drainage plate 11 and the conveyor belt 7 increases, thereby improving the drainage effect of the drainage plate 11 and increasing the flow-through efficiency of the filter mesh opening 14;

[0061] When the sewage discharge continues to increase or the pollutants in the sewage continue to increase, the processing module receives the pressure information at the current moment from the gravity sensor and forms judgment information. The control module receives the judgment information and controls the electric driving member 63, the electric support base 82, and the motor 13 according to the judgment information; the horizontal inclination angle of the guide plate 81 increases to prevent pollutants from accumulating on the guide plate 81;

[0062] Meanwhile, the telescopic end of the electric driving member 63 contracts, the electric driving member 63 pulls the sliding seat 62, the sliding seat 62 slides upward along the arc-shaped guide rail 61, the sliding seat 62 drives the second driving roller 5 to move synchronously, and the horizontal inclination angle of the conveyor belt 7 is reduced by the position movement of the second driving roller 5, so as to adjust the load-bearing capacity of the conveyor belt 7 for pollutants and prevent the pollutants from sliding down from the conveyor belt 7 when there are too many pollutants.

[0063] The increase in the rotation speed of the motor 13 drives the conveyor belt 7 to convey faster. Meanwhile, the horizontal inclination angle of the flow guide plate 81 increases. Increasing the inclination angle of the flow guide plate 81 can prevent pollutants from accumulating on the flow guide plate 81.

[0064] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0065] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
