Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a sewage treatment system with high chemical agent mixing efficiency. Background Art

[0002] With the improvement of people's living conditions, the construction of urban buildings is also increasing, and the sewage generated in the city is also increasing. The treatment of sewage in the city is also an important part. Some food processing plants or industrial factories will be built near the city, but these factories will generate some sewage. Usually, food or industrial factories have independent sewage treatment areas, but the sewage generated by urban residential areas needs to be treated separately. The treatment steps of domestic sewage are numerous, such as sedimentation, removal of floating objects, and addition of chemical agents to remove microorganisms, etc.

[0003] In the prior art, for the treatment of domestic sewage, sedimentation and removal of floating objects are relatively common and mature methods. For the addition of chemical agents, it is usually impossible to achieve uniform dispersion of the chemical agents in the sewage. In the prior art, in order to disperse the chemical agents evenly in the sewage, stirring is usually used to make the chemical agents evenly dispersed in the sewage. This way of dispersing the chemical agents requires stirring the sewage. However, during the stirring process, stirring dead angles will inevitably be generated, and the technical requirement of uniform distribution of the chemical agents in the sewage still cannot be met.

[0004] Therefore, there is a technical problem that the chemical agents in the sewage treatment equipment in the prior art are not evenly dispersed in the sewage. Summary of the Invention

[0007] Preferably, the liquid supply tank is inclined, and the liquid in the liquid supply tank enters the mixing barrel under the action of gravity, and the height of one end of the liquid supply tank close to the mixing barrel is lower than the height of the end of the liquid supply tank far from the mixing barrel.

[0008] Preferably, a liquid preparation tank is arranged at one end of the liquid supply tank far from the mixing barrel, the liquid preparation tank communicates with the liquid supply channel through a liquid discharge tank, the sewage to be treated in the liquid preparation tank enters the liquid supply channel through the liquid discharge tank, and the width of the liquid discharge tank is equal to the width of the liquid supply channel.

[0009] Preferably, a partition plate is arranged between the liquid preparation tank and the liquid supply channel, the liquid discharge tank is arranged on the partition plate, and the liquid discharge tank penetrates through the partition plate. The height of the liquid discharge tank is not greater than 5 mm, and there are multiple liquid discharge tanks, and the multiple liquid discharge tanks are arranged along the height direction of the partition plate.

[0010] Preferably, the liquid supply tank is further provided with a chemical addition tank, the chemical addition tank is provided with a chemical addition chamber, the chemical addition tank is also provided with a chemical discharge chamber, the chemical agent in the chemical addition chamber enters the liquid supply channel through the chemical discharge chamber under the action of gravity, and the sewage output from the liquid discharge tank and the chemical agent output from the chemical discharge chamber are mixed in the liquid supply channel.

[0011] Preferably, the chemical discharge chamber straddles the liquid supply channel, and the direction of discharging the chemical agent into the liquid supply channel by the chemical discharge chamber is perpendicular to the direction of discharging the sewage into the liquid supply channel by the liquid discharge tank.

[0012] Preferably, the cross-sectional shape of the chemical discharge chamber is a trapezoid with a wider upper part and a narrower lower part, and the chemical discharge tank is welded to the liquid supply tank.

[0013] Preferably, the guiding plate is welded to the liquid drainage groove. The cross-sectional shape of the guiding surface is arc-shaped. The guiding surface protrudes from the bottom wall of the liquid drainage groove. The height of the guiding plate is less than the depth of the liquid supply channel.

[0014] Preferably, there are multiple guiding plates. The multiple guiding plates are evenly arranged along the length direction of the liquid supply channel. A flow guiding plate is arranged between two adjacent guiding plates. The cross-sectional shape of the flow guiding plate is V-shaped. Moreover, the tip of the flow guiding plate faces the direction away from the mixing assembly of the liquid supply tank. There are multiple flow guiding plates.

Another part of the liquid flows through the guiding plate through the through hole. The liquid guided by the guiding surface and the liquid flowing through the guiding plate through the through hole converge at the rear side of the guiding plate. Since the liquid guided by the guiding surface will generate a certain potential energy, when this part of the liquid moves towards the bottom wall of the liquid supply channel again through the guiding surface, it will impact the liquid flowing through the through hole, so that the liquid can be mixed in the liquid supply channel. And this kind of mixing is achieved by the mutual impact of two parts of the liquid, greatly improving the mixing effect and the mixing efficiency.

[0017] By arranging the mixing barrel, the liquid that has been mixed in the liquid supply channel enters the mixing barrel and is then remixed by the stirrer. Since the liquid has been preliminarily mixed in the liquid supply channel, when the preliminarily mixed liquid enters the mixing barrel for mixing, it can be mixed without a long stirring time, effectively improving the mixing efficiency of the liquid, making the medicament more evenly distributed in the sewage, and optimizing the mixing quality.

[0018] By arranging the flow divider, the flow divider enables the liquid in the mixing barrel to be remixed again during the process of entering the treatment assembly, making the liquid medicament entering the treatment assembly more evenly distributed in the sewage, thereby further improving the mixing effect of the medicament and the sewage, and then optimizing the sewage treatment performance of the sewage treatment system.

[0029] The specific embodiments shown below are intended as descriptions of various configurations of the technology of the subject matter of the present invention, and are not intended to represent the only configurations in which the technology of the subject matter of the present invention can be practiced. The specific embodiments include specific details intended to provide a thorough understanding of the technology of the subject matter of the present invention. However, it will be clear and obvious to those skilled in the art that the technology of the subject matter of the present invention is not limited to the specific details shown herein, and can be practiced without these specific details.

[0030] It can be understood that, herein, relational terms such as "first" and "second" are intended to distinguish one entity or operation from another entity or operation, and are not intended to imply any actual relationship or order between these entities or operations.

[0031] The term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or apparatus comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or apparatus. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or apparatus comprising the element.

[0032] Referring Figures 1 to 6 As shown, a sewage treatment system with high pharmaceutical mixing efficiency includes a liquid supply component 1; a mixing component 2, and the liquid supply component 1 supplies liquid into the mixing component 2; and a treatment component 3, the treatment component 3 communicates with the mixing component 2, and the liquid mixed in the mixing component 2 enters the treatment component 3; Among them, the liquid supply component 1 includes a liquid supply tank 11, the liquid supply tank 11 is provided with a liquid supply channel 12 communicating with the mixing component 2, the liquid supply channel 12 is provided with a guide plate 13 for guiding the liquid flowing in the liquid supply channel 12, the guide plate 13 is provided with a through hole 131 for the liquid to pass through, the guide plate 13 includes a guide surface 132 for guiding the liquid, a part of the liquid in the liquid supply channel 12 flows through the guide plate 13 through the through hole, another part of the liquid in the liquid supply channel 12 flows through the guide plate 13 through the guide surface 132, and the liquid guided by the guide surface 132 re-enters the liquid supply channel 12 under the action of gravity and mixes with the liquid guided by the through hole 131 in the liquid supply channel 12; The mixing component 2 includes a mixing barrel 21, a stirrer 22 is arranged in the mixing barrel 21, the mixing barrel 21 communicates with the treatment component 3 through a drain channel 24, a control valve 23 is arranged in the drain channel 24, and a diverter 25 for remixing the liquid passing through the drain channel 24 is also arranged in the drain channel 24.

[0033] It can be understood that the liquid has a certain amount of energy during the flow in the liquid supply channel 12, and this energy causes a part of the liquid to be guided by the guide surface 132, and another part of the liquid flows through the guide plate 13 through the through hole 131. The front side of the guide plate 13 faces the direction of the surface directly impacted by the liquid in the liquid supply channel 12, and the side opposite to the front side is the rear side of the guide plate 13.

[0034] When the liquid in front of the guiding plate 13 comes into contact with the guiding plate 13, a part of the liquid is guided by the guiding surface 132 to move away from the bottom wall of the liquid supply channel 12, and the other part of the liquid passes through the guiding plate 13 via the through hole 131. After the liquid guided by the guiding surface 132 flows through the guiding surface 132, it will fall to the rear side of the guiding plate 13 under the action of gravity, and the liquid flowing through the through hole 131 will also enter the rear side of the guiding plate 13. The two parts of the liquid converge at the rear side of the guiding plate 13. Since the liquid guided by the guiding surface 132 has a certain potential energy, this part of the liquid will impact the liquid flowing through the through hole 131, thereby realizing the mixing of the liquid at the rear side of the guiding plate 13.

[0035] Meanwhile, this mixing is formed by the impact of the liquid, and this mixing method has a higher mixing efficiency and more uniform mixing compared with the mixing method using stirring.

[0036] It can be understood that the more the number of guiding plates 13, the more times the liquid is mixed in the liquid supply channel 12, and the more uniform the liquid mixing is.

[0037] The liquid that has been mixed in the liquid supply channel 12 then enters the mixing barrel 21 and is stirred by the stirrer 22, and the liquid is mixed again in the mixing barrel 21 by means of stirring.

[0038] Refer to Figures 1 to 6 As shown, the liquid that has been mixed in the mixing barrel 21 by means of stirring then enters the processing assembly 3 through the control valve 23 and the diverter 25, and precipitation or other processing is completed in the processing assembly 3. The diverter 25 is used to disperse the liquid in the liquid discharge channel 24 and has a certain mixing effect.

[0039] In some embodiments, the stirrer 22 includes a stirring shaft 221, and stirring blades are arranged on the stirring shaft 221. The stirring shaft 221 is driven by a motor 222 installed on the mixing barrel 21. During the rotation process, the stirring shaft 221 mixes the liquid in the mixing barrel through the stirring blades.

[0040] In some embodiments, a bracket 223 for fixing the motor 222 can be arranged at the upper end of the mixing barrel 21, and the bracket 223 can be fixed to the mixing barrel by screws. The bracket 223 can be formed by welding rods. The motor 222 can be fixed to the bracket 223 by bolts.

[0041] In some embodiments, the stirring blades can include an upper stirring blade 224 and a lower stirring blade 225. The upper stirring blade 224 guides the liquid above the mixing barrel 21 to move downward during the process of stirring the liquid, and the lower stirring blade 225 guides the liquid below the mixing barrel 21 to move upward during the process of stirring the liquid, so as to make the liquid mix more uniformly in the mixing cylinder.

[0042] In some embodiments, the upper stirring blade 224 and the lower stirring blade 225 may be staggeredly arranged.

[0043] In some embodiments, both the upper stirring blade 224 and the lower stirring blade 225 may be welded to the stirring shaft 221.

[0044] In some embodiments, both the upper stirring blade 224 and the lower stirring blade 225 are three-dimensional curved surfaces, similar to the shape of a propeller.

[0045] In some embodiments, the processing assembly 3 includes a processing barrel.

[0046] In some embodiments, the control valve 23 may be a solenoid valve or a manual valve. When the control valve 23 opens the liquid discharge channel 24, the liquid located in the mixing barrel 21 enters the processing barrel. When the control valve 23 closes the liquid discharge channel 24, the mixing barrel 21 is not connected to the processing barrel.

[0047] In some embodiments, when the stirring time of the liquid in the mixing barrel 21 reaches, the control valve 23 can be automatically opened, so that the liquid after being mixed in the mixing barrel 21 enters the processing barrel.

[0048] In some embodiments, both the motor 222 and the control valve 23 can be centrally controlled by a controller.

[0049] Refer to Figures 1 to 6 As shown, in some embodiments, the liquid supply tank 11 is inclined, and the liquid located in the liquid supply tank 11 enters the mixing barrel 21 under the action of gravity. The height of one end of the liquid supply tank 11 close to the mixing barrel 21 is lower than the height of the end of the liquid supply tank 11 far from the mixing barrel 21. The inclined arrangement of the liquid supply tank 11 enables the liquid in the liquid supply channel 12 to be completely discharged into the mixing barrel 21, preventing the liquid from staying in the liquid supply channel 12.

[0050] In some embodiments, a liquid preparation tank 14 is provided at one end of the liquid supply tank 11 far from the mixing barrel 21. The liquid preparation tank 14 communicates with the liquid supply channel 12 through a liquid discharge tank 141. The wastewater to be treated located in the liquid preparation tank 14 enters the liquid supply channel 12 through the liquid discharge tank 141. The width of the liquid discharge tank 141 is equal to the width of the liquid supply channel 12.

[0051] In some embodiments, the liquid preparation tank 14 can be independently arranged, or the liquid preparation tank 14 can also be a part of the liquid supply tank 11.

[0052] In some embodiments, the height of the liquid discharge tank 141 should be as narrow as possible. That is, when the liquid flows through the liquid discharge tank 141 and enters the liquid supply channel 12, the liquid discharge tank 141 enables the liquid to enter the liquid supply channel 12 in the form of a water curtain, so that the liquid can be evenly distributed along the width direction of the liquid supply channel 12.

[0053] The more evenly the liquid is distributed in the liquid supply channel 12, the more conducive it is to the mixing of the medicament and the sewage, which is beneficial to improving the mixing efficiency.

[0054] Refer to Figures 1 to 6 As shown, in some embodiments, the liquid distribution tank 14 and the liquid supply tank 11 are of an integral structure. A partition plate 142 is provided between the liquid distribution tank 14 and the liquid supply channel 12. The liquid discharge tank 141 is provided on the partition plate 142. Moreover, the liquid discharge tank 141 penetrates through the partition plate 142. The height of the liquid discharge tank 141 is not greater than 5 mm. There are multiple liquid discharge tanks 141, and the multiple liquid discharge tanks 141 are arranged along the height direction of the partition plate 142.

[0055] When the liquid in the liquid distribution tank 14 enters the liquid supply channel 12 through the liquid discharge tank 141, it enters the liquid supply channel 12 in the form of a water curtain.

[0056] Refer to Figures 1 to 2 As shown, in some embodiments, the liquid supply tank 11 is further provided with a medicine adding tank 15. The medicine adding tank 15 is provided with a medicine adding cavity 151. The medicine adding tank 15 is further provided with a medicine discharging cavity 152. The medicament in the medicine adding cavity 151 enters the liquid supply channel 12 through the medicine discharging cavity 152 under the action of gravity. Moreover, the sewage output by the liquid discharge tank 141 and the medicament output by the medicine discharging cavity 152 are mixed in the liquid supply channel 12.

[0057] When the medicament enters the liquid supply channel 12 through the medicine discharging cavity 152, the medicament can enter the liquid supply channel 12 in the form of a water curtain, so that the medicament and the sewage in the liquid supply channel 12 can be evenly mixed.

[0058] In some embodiments, the medicine discharging cavity 152 straddles the liquid supply channel 12. Moreover, the direction in which the medicine discharging cavity 152 discharges the medicament into the liquid supply channel 12 is perpendicular to the direction in which the liquid discharge tank 141 discharges the sewage into the liquid supply channel 12.

[0059] During the process of the medicament entering the liquid discharge channel 24, the medicament will impact the sewage or liquid in the liquid supply channel 12, and this impact will evenly disperse the medicament in the sewage or liquid in the liquid supply channel 12.

[0060] It can be understood that the thinner the water curtain formed by the medicament by the medicine discharging cavity 152 and the water curtain formed by the sewage by the liquid discharge tank 141 are, the better the mixing effect of the medicament and the sewage is, and the more beneficial it is to improving the mixing efficiency of the medicament and the sewage.

[0061] In some embodiments, the sewage can be supplied into the liquid distribution cavity through a pipeline or a sewage pump. The medicament can be supplied into the medicine adding cavity 151 through a medicine pump. Both the sewage pump and the medicine pump can be centrally controlled by a controller.

[0062] In some embodiments, the cross-sectional shape of the medicine discharging cavity 152 is a trapezoid that is wider at the top and narrower at the bottom, and the medicine discharging groove is welded to the liquid supply groove 11. This enables the medicine in the medicine adding cavity 151 to completely enter the medicine discharging cavity 152, preventing the medicine from remaining in the medicine adding cavity 151.

[0063] Refer to Figures 1 to 4 As shown, in some embodiments, the guiding plate 13 is welded to the liquid discharging groove 141. The cross-sectional shape of the guiding surface 132 is arc-shaped, the guiding surface 132 protrudes from the bottom wall of the liquid discharging groove 141, and the height of the guiding plate 13 is less than the depth of the liquid supply channel 12.

[0064] It can be understood that the guiding plate 13 should not protrude from the liquid discharging groove 141 to prevent sewage from splashing out of the liquid discharging channel 24.

[0065] In some embodiments, there are multiple guiding plates 13, and the multiple guiding plates 13 are uniformly arranged along the length direction of the liquid supply channel 12. It can be understood that the more the number of guiding plates 13, the better the mixing effect of the liquid.

[0066] In some embodiments, a flow guiding plate 16 is arranged between two adjacent guiding plates 13. The cross-sectional shape of the flow guiding plate 16 is V-shaped, and the tip of the flow guiding plate 16 faces away from the mixing assembly 2 of the liquid supply groove 11. There are multiple flow guiding plates 16, and the multiple flow guiding plates 16 are distributed along the length direction of the liquid supply channel 12. Along the flowing direction of the liquid in the liquid supply channel 12, two adjacent flow guiding plates 16 are staggeredly arranged.

[0067] The flow guiding plate 16 causes the liquid located in the liquid supply channel 12 to be repeatedly divided and guided, making the liquid mix more evenly in the liquid supply channel.

[0068] In some embodiments, the width of the liquid discharging channel 24 does not exceed 5 mm. The diverter 25 is a diverting column welded in the liquid discharging channel 24 and straddling the liquid discharging channel 24. The cross-sectional shape of the diverting column is polygonal, or the cross-sectional shape of the diverting column is circular.

[0069] In some embodiments, the liquid discharging channel 24 can be formed by liquid discharging plates. There can be two or more liquid discharging plates. One end of the liquid discharging plate is welded to the mixing barrel 21, and the other end of the liquid discharging plate is welded to the treatment barrel to prevent the mixing barrel 21 or the treatment barrel from leaking. The liquid discharging channel 24 is formed between two adjacent liquid discharging plates.

[0070] In some embodiments, the function of the diverting column is similar to that of the flow guiding plate 16, both for further mixing the liquid, so that the sewage and the medicine in the treatment barrel are mixed more evenly, which is beneficial to improving the sewage treatment efficiency.

[0071] The above has introduced the technical solution of the subject matter of the present invention and the corresponding details. It can be understood that the above introduction is only some implementation solutions of the technical solution of the subject matter of the present invention, and some details can also be omitted during its specific implementation.

[0072] In addition, in some implementation solutions of the above invention, it is possible to implement multiple implementation solutions in combination. Due to space limitations, various combination solutions will not be listed one by one. Those skilled in the art can freely combine and implement the above implementation solutions according to their needs during specific implementation to obtain a better application experience.

[0073] When implementing the technical solution of the subject matter of the present invention, those skilled in the art can obtain other detailed configurations or drawings according to the technical solution of the subject matter of the present invention and the drawings. Obviously, without departing from the technical solution of the subject matter of the present invention, these details still fall within the scope covered by the technical solution of the subject matter of the present invention.
