[0018] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0019] In the following description, the example details are given to provide a deeper understanding of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. It should be understood that the specific embodiments are only used to explain the present invention and are not used to limit the present invention.

[0020] It should be understood that when the terms "include" and / or "comprises" are used in this specification, they indicate the existence of the stated features, integers, steps, operations, elements or components, but do not exclude the existence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0021] See also Figure 1-Figure 6 The present invention provides a cubic environmental protection tank sewage separation and treatment system, comprising: The environmental protection cylinder includes a mixing box 2 and a separation box 1; a mixing and stirring motor 2421 is arranged above the mixing box 2, the output end of the mixing and stirring motor 2421 is connected to the mixing and stirring fan blade 2522, a sewage pipe 3 is connected to the mixing box 2, a plurality of liquid medicine barrels 4 are arranged below the mixing box 2, and the liquid medicine barrels 4 are connected to the mixing box 2 through a liquid medicine delivery pipe 41, and an overflow port 5 connected to the separation box 1 is also arranged on the wall of the mixing box 2, a filter screen 6 and a plurality of parallel pipes 7 laid on the filter screen 6 are arranged in the separation box 1, and the plurality of parallel pipes 7 are inclined or vertical relative to the filter screen 6 and are arranged with gaps; a drainage groove 8 is also arranged on the separation box 1, and the drainage groove 8 is connected to the drainage port 9; When the sewage enters the mixing box 2, the liquid medicine barrel 4 releases chemicals to react with the sewage, and then enters the separation box 1 through the overflow port 5. The sewage accumulates at the bottom of the separation box 1 and rises to the parallel pipe 7. The parallel pipe 7 and the filter screen 6 separate the impurities in the sewage. The filtered sewage rises to the drain trough 8 and is discharged through the drain port 9.

[0022] When sewage enters the mixing box 2 from the sewage pipe 3, a liquid medicine for adjusting the pH value of the acid or alkali is added to the mixing box 2 through the liquid medicine barrel 4, and the mixing and stirring motor 2421 is started. The mixing and stirring fan blades 2522 fully and quickly react the sewage and the liquid medicine to adjust the pH value of the sewage. Then, when the sewage water level in the mixing box 2 after adjusting the pH value continues to rise, until the water level reaches the overflow port 5, it flows into the separation box 1 through the overflow port 5. The adjusted sewage also contains large impurities such as soil, sand or branches. The sewage in the mixing box 2 continuously flows into the separation box 1, so that the sewage water level in the separation box 1 rises to the filter screen 6. The filter screen 6 can block large impurities, and the multiple sets of parallel tubes 7 arranged on the filter screen 6 can further separate the fine impurities such as soil contained in the sewage. Since there is a certain gap between each parallel tube 7, and the parallel tube 7 itself has a cavity, when the sewage rises to the parallel tube 7, the slowly rising sewage forms a laminar flow through multiple groups of inclined parallel tubes 7, and the suspended matter and particulate matter in the sewage are greater than the density of the water body, resulting in the water body continuing to rise upward, and the suspended matter and particulate matter precipitate downward, and finally the sewage that meets the discharge standard flows out through the drainage trough 8 to the drainage port 9 to be discharged to the outside; wherein, the parallel tube 7 of the present invention is mainly made of but not limited to PVC material, PVC has excellent chemical stability and is safe, environmentally friendly and non-toxic, can resist the erosion of most chemical substances, and has a large wet perimeter and a small hydraulic radius, a good laminar flow state, and particle precipitation is not easily disturbed by flocculation, etc. These characteristics help to improve the efficiency of sewage treatment.

[0023] The working principle of the present invention is: First, the sewage enters the mixing box 2 through the sewage pipe 3. After the water flow sensor of the sewage pipe 3 detects the inflow of sewage, the equipment is started. Before the sewage is precipitated, the pH value of the sewage is first adjusted. The metering pump 23 extracts the reagent in the liquid medicine barrel 4 and inputs the chemical reagent into the mixing box 2 through the liquid medicine delivery pipe 41. Then the coagulation and stirring motor 24 is started, and the mixing and stirring fan blades 2522 are stirred. Combined with the buffer plate 10 in the mixing box 2, the chemical reaction between the reagent and the sewage is accelerated. The pH value of the sewage is then detected by the pH value detection probe 15. When the pH value of the sewage meets the standard, the delivery of the liquid medicine is stopped. On the contrary, if the pH value is unqualified, the delivery of the liquid medicine continues. After the water quality is qualified, sewage continues to flow into the mixing box 2. After rising to a certain height, the sewage with the adjusted pH value flows into the separation box 1 along with impurities. A sewage discharge pipe 12 and a sewage discharge valve 13 are provided at the bottom of the separation box 1. When the water in the separation box 1 accumulates When it rises to the filter screen 6, the sewage is separated from impurities for the first time. The filter screen 6 is covered with inclined or vertically arranged PVC parallel pipes 7, and a gap is set between two adjacent pipes to divide and form a smaller sedimentation area. Therefore, when the sewage slowly rises to the parallel pipes 7, the sewage is diverted due to the parallel pipes 7, and impurities with larger density are separated from the sewage by the PVC parallel pipes 7, and the impurities sink and are discharged to the outside through the sewage pipe 12. If they cannot be cleaned, the inspection door 14 can be opened for cleaning. After the water body is separated from the impurities, the water level continues to rise to the drainage trough 8, and flows out to the outside along the drainage trough 8 to the drainage port 9, and finally the sewage purification and separation is completed; when there is no subsequent sewage inflow, the sewage in the mixing box 2 can be discharged through the sewage outlet 11, and the sewage in the separation box 1 is discharged from the sewage pipe 12. The impurities attached to the parallel pipes 7 or the wall of the separation box 1 can be washed by connecting a high-pressure water gun to the outside to maintain the environmental protection cylinder.

[0024] The present invention is provided with a plurality of medicine liquid barrels 4, and each medicine liquid barrel 4 is provided with a metering liquid pump 23 and a water level detection probe for detecting the height of the medicine liquid inside the medicine liquid barrel 4. The water pumping end of the metering liquid pump 23 is connected to the medicine liquid barrel 4 through a pipeline, and the water outlet end conveys the medicine liquid to the mixing box 2 through the medicine liquid conveying pipeline 41. When the medicine liquid level in the medicine liquid barrel 4 drops to the same level as the water level monitoring probe, an alarm is sounded through an alarm or a red light flashes through an indicator light to prompt the staff to add medicine liquid to ensure the normal operation and decontamination of the machine. After the medicine liquid is added, the alarm is automatically lifted; the metering liquid pump 23 can accurately control the dosage of the added medicine liquid through the control of the PLC to ensure that the sewage is at the correct pH value; it also includes a liquid level alarm for the medicine liquid barrel 4, and the detection end of the liquid level alarm for the medicine liquid barrel 4 is arranged on the medicine liquid barrel 4. In the barrel 4, the liquid level alarm of the medicine barrel 4 is used to detect the water level of the medicine in the medicine barrel 4 to ensure that the medicine in the medicine barrel 4 is sufficient. When the medicine in the medicine barrel 4 is insufficient, the alarm end of the liquid level alarm of the medicine barrel 4 will sound an alarm to prompt the on-site personnel; and it also includes a stirring motor 24 and a stirring fan blade 25 connected to the stirring motor 24. The stirring motor 24 is arranged on the medicine barrel 4, and the stirring fan blade 25 is accommodated in the medicine barrel 4. The stirring motor 24 is mainly used to stir the chemical liquid in the medicine barrel 4 to prevent coagulation. The chemical liquid generally used for sewage purification includes but is not limited to polyacrylamide, polyan alumina, sodium bisulfate and other chemical liquids. This type of liquid is generally easy to coagulate when left standing at room temperature. Stirring the liquid with the stirring fan blade 25 can make the liquid flow and reduce the problem of coagulation.

[0025] In another embodiment, all the technical features of the above-mentioned embodiments are included. The blades of the mixing and stirring blades 2522 are inclined relative to the wall of the mixing box 2. The water flow will generate an oblique water flow along the inclination direction of the blades, which is helpful to generate a more complex flow path during the stirring process, generate more turbulence, and help to improve the diffusion and reaction rate of the liquid medicine and improve the mixing effect; further, in order to achieve a better mixing effect, the wall of the mixing box 2 is provided with a plurality of buffer plates 10, and the bottom of the mixing box 2 is also provided with a sewage outlet 11. The mixing and stirring motor 2421 combined with the buffer plate 10 can speed up the sewage and liquid medicine. The chemical reaction realizes the full fusion of sewage and liquid medicine. When the motor starts, the mixing and stirring blades 2522 rotate and stir in the sewage. The sewage flows in the direction of rotation and collides with the buffer plate 10. The buffer plate 10 blocks the sewage and generates a reaction force. The blocked sewage collides with the sewage stirred by the blades, further enhancing the mixing effect. When the addition of sewage stops, the sewage level in the mixing box 2 stops rising. At this time, the remaining sewage needs to be discharged through the sewage outlet 11, and the mixing box 2 is cleaned through an externally connected high-pressure water gun to ensure that the inside of the mixing box 2 is clean and extend the service life of the equipment.

The water flow sensor is arranged on the sewage pipe 3 to detect whether there is sewage flowing into the sewage pipe 3, so as to control the start and pause of the environmental protection cylinder. If no sewage inflow is detected in the sewage pipe 3, the environmental protection cylinder equipment is automatically stopped through PLC control. After the sewage inflow is detected, the equipment is started.

[0027] In another embodiment, all the technical features of the above-mentioned embodiments are included, and a pH value detection probe 15 is also included. The pH value detection probe 15 is arranged in the mixing box 2, and is used to detect the pH value of the water quality to control whether the metering liquid pump 23 delivers the medicine. The pH value detection probe 15 can detect the pH value of the sewage in the mixing box 2 in real time to ensure that the sewage and the medicine are fully mixed and the pH value of the sewage meets the discharge standard.

[0028] In another embodiment, all the technical features of the above-mentioned embodiments are included, and a sewage pipe 12 and a sewage valve 13 are also provided on the wall of the separation box 1, and the sewage valve 13 is fixedly arranged on the sewage pipe 12; the impurities in the separation box 1 are discharged to the outside of the sewage pipe 12 through a mud discharge pipe, and when the sewage in the separation box 1 is diverted, the water moves upward, and the impurities are accumulated at the bottom of the separation box 1, and the continuously added sewage causes the impurities to be slowly pushed out of the sewage pipe 12; an inspection door 14 is provided on the separation box 1, and on-site personnel can enter the separation box 1 through the inspection door 14 to manually clean up the residual impurities in the separation box 1.

[0029] The advantages of the present invention are: The present invention mainly separates impurities in sewage through parallel pipes, utilizes the laminar flow principle, keeps the water body at a uniform flow rate for sedimentation and impurity removal, and combines with a funnel-shaped separation box to accelerate the precipitation of impurities and the rise of sewage.
