Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment box and a treatment system. Background Art

[0002] In the sewage treatment process, the removal of suspended solids is a crucial step. Suspended solids not only affect water quality, but may also cause damage to subsequent treatment equipment. Suspended solids are organic and inorganic particles suspended in the water that cannot pass through 0.45 micron filter paper or filters. Such as silt, clay, organic matter, algae and microorganisms that are difficult to dissolve in water, is one of the indicators to measure the degree of water pollution.

[0003] The existing technology for removing suspended solids in sewage generally includes filtration or sedimentation followed by separation. The general filtration method requires regular replacement of the filter element, which is costly and complex to replace, and is time-consuming and labor-intensive. The separation efficiency is low and the separation effect is poor by adopting the sedimentation followed by separation method. Utility Model Content

[0004] In order to solve the problems of complex filter element replacement and poor separation effect in the prior art, the present application provides a sewage treatment box and a treatment system.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is: a sewage treatment tank, comprising: an impurity precipitation assembly, the impurity precipitation assembly comprises an impurity precipitation tank and a plurality of supporting legs arranged on the impurity precipitation tank, a liquid inlet pipe and a drainage pipe are arranged on the impurity precipitation tank, the liquid inlet pipe and the drainage pipe are both connected to the impurity precipitation tank, and a sewage pipe is connected to the bottom of the impurity precipitation tank; a suspended matter filtration assembly, the suspended matter filtration assembly comprises a diversion pipe connected to the drainage pipe and a suspended matter separator connected to the diversion pipe, the suspended matter separator comprises a filter cartridge and an adjustment cartridge, the filter cartridge is connected and arranged on the diversion pipe, the adjustment cartridge is sleeved on the filter cartridge, and the adjustment cartridge can rotate freely around the central axis of the filter cartridge, the filter cartridge is evenly spaced with first through holes, and the adjustment cartridge is provided with a second through hole that can coincide with the central axis of the first through hole.

[0006] In some embodiments of the utility model, the liquid inlet pipeline is connected in series with a first control valve for controlling the sewage to enter the impurity sedimentation tank.

[0007] In some embodiments of the utility model, an inspection mechanism is provided at the output end of the above-mentioned diversion pipeline, and the inspection mechanism includes a second control valve connected in series to the diversion pipeline and a pressure gauge arranged on the diversion pipeline.

[0009] In some embodiments of the present invention, the mouth of the impurity precipitation tank is covered with a cover body, and a handle is provided on the cover body.

[0010] In some embodiments of the utility model, a conical guide hopper is provided at the bottom of the impurity precipitation tank, and the sewage discharge pipe is located at the output end of the conical guide hopper.

[0011] The utility model also provides a sewage treatment system, comprising at least two sewage treatment boxes, and adjacent sewage treatment boxes are connected through a liquid inlet pipe and a drainage pipe.

[0012] Beneficial effects:

[0013] 1. The above-mentioned impurity precipitation component is used to remove the heavy suspended matter and light suspended matter in the suspension by automatic sedimentation and filtration, respectively, to improve the effect and efficiency of sewage treatment. Specifically, the above-mentioned impurity precipitation tank is used for the sedimentation of heavy suspended matter. When the sewage enters the impurity precipitation tank through drainage, the heavy suspended matter sinks vertically and is deposited at the bottom of the impurity precipitation tank because its own gravity is greater than the buoyancy, which is convenient for centralized treatment. The above-mentioned support legs are used to lift the entire impurity precipitation tank, which is convenient for the installation of the sewage pipe, thereby facilitating the collection and discharge of heavy pollutants. The above-mentioned liquid inlet pipe is used for the entry of sewage, and the sewage is diverted into the impurity precipitation tank for sedimentation, filtration and impurity removal. The above-mentioned drainage pipe is used to divert the water body after sedimentation and filtration to the next treatment process. The above-mentioned sewage pipe is used to remove the heavy suspended matter deposited at the bottom of the impurity precipitation tank, which is convenient for the subsequent sedimentation operation.

[0014] 2. The suspended matter filter assembly is used to filter light suspended matter, so that it can effectively remove suspended impurities during sewage treatment. The suspended matter filter assembly is used to form a filter net through the synergistic effect of a filter cartridge and an adjustment cartridge. When in use, the size of the first through hole on the filter cartridge through which the water passes is adjusted by rotating the adjustment cartridge sleeved on the outside of the filter cartridge. When the center axis of the first through hole on the filter cartridge coincides with the center axis of the second through hole, the diameter of the water flow through the filter cartridge is the largest. When the center axis of the second through hole deviates from the center axis of the first through hole, the diameter of the channel through the water body continues to decrease, so that the size of the light suspended matter that can pass through gradually decreases.

[0015] 3. By connecting multiple sewage treatment tanks end to end and controlling the size of impurities passing through the suspended matter filters inside different sewage tanks, the filtration accuracy can be continuously improved, thereby obtaining cleaner water and facilitating subsequent treatment.

[0029] Embodiment 1:

[0030] Please refer to Figure 1-Figure 4The present embodiment provides a sewage treatment tank, comprising: an impurity precipitation component, the impurity precipitation component comprises an impurity precipitation tank 1 and a plurality of supporting legs 2 arranged on the impurity precipitation tank 1, a liquid inlet pipe 3 and a drainage pipe 4 are arranged on the impurity precipitation tank 1, the liquid inlet pipe 3 and the drainage pipe 4 are both connected to the impurity precipitation tank 1, and a sewage pipe 5 is connected to the bottom of the impurity precipitation tank 1; a suspended matter filtering component, the suspended matter filtering component comprises a guide pipe 6 connected to the drainage pipe 4 and a suspended matter separator 7 connected to the guide pipe 6, the suspended matter separator 7 comprises a filter cartridge 701 and an adjustment cartridge 702, the filter cartridge 701 is connected and arranged on the guide pipe 6, the adjustment cartridge 702 is sleeved on the filter cartridge 701, and the adjustment cartridge 702 can rotate freely around the central axis of the filter cartridge 701, the filter cartridge 701 is evenly spaced with first through holes 8, and the adjustment cartridge 702 is provided with a second through hole 9 that can coincide with the central axis of the first through hole 8.

[0031] It should be noted that the physical properties of suspended solids, such as particle size, shape and density, have an important influence on their behavior and separation in water. Light suspended solids may float, while solid particles will sink. These characteristics make it possible to effectively remove suspended solids during sewage treatment by adjusting water flow conditions or using physical separation techniques.

[0032] In this embodiment, the impurity precipitation assembly is used to remove solid particles and light suspended solids in the liquid by automatic sedimentation and filtration, respectively, so as to improve the effect and efficiency of sewage treatment. Specifically, the impurity precipitation tank 1 is used for the sedimentation of solid particles. When the sewage enters the impurity precipitation tank through drainage, the solid particles sink vertically because their own gravity is greater than the buoyancy, and are deposited at the bottom of the impurity precipitation tank 1, which is convenient for centralized treatment. The support legs 2 are used to lift the entire impurity precipitation tank 1, which is convenient for installing the sewage pipe, so as to facilitate the collection and discharge of heavy pollutants. The liquid inlet pipe 3 is used for the entry of sewage, and the sewage is diverted into the impurity precipitation tank 1 for sedimentation, filtration and impurity removal. The drainage pipe 4 is used to divert the water body after sedimentation and filtration to the next treatment process. The sewage pipe is used to remove the solid particles deposited at the bottom of the impurity precipitation tank 1, which is convenient for the subsequent sedimentation operation.

[0033] In this embodiment, the suspended matter filter assembly is used to filter light suspended matter, so that suspended impurities can be effectively removed during sewage treatment. The suspended matter filter assembly is used to form a filter screen through the synergistic action of the filter cartridge 701 and the adjustment cartridge 702. When in use, the size of the first through hole 8 on the filter cartridge 701 through which the water passes is adjusted by rotating the adjustment cartridge 702 sleeved on the outside of the filter cartridge 701. When the center axis of the first through hole 8 on the filter cartridge 701 coincides with the center axis of the second through hole 9, the diameter of the water flow through the filter cartridge 701 is the largest. When the center axis of the second through hole 9 deviates from the center axis of the first through hole 8, the diameter of the channel through the water body continues to decrease, thereby gradually reducing the size of the light suspended matter that can pass through.

[0034] Please refer to Figure 1-Figure 4 In some implementations of the present embodiment, the liquid inlet pipe 3 is connected in series with a first control valve 10 for controlling the entry of sewage into the impurity sedimentation tank 1 .

[0035] In this embodiment, the first control valve 10 is used to control the sewage to be purified to enter the impurity sedimentation tank 1, so as to facilitate the discharge of pollutants deposited inside the impurity sedimentation tank 1.

[0036] Please refer to Figure 1-Figure 4 In some implementations of the present embodiment, an inspection mechanism is provided at the output end of the above-mentioned guide pipe 6, and the inspection mechanism includes a second control valve 11 connected in series to the guide pipe 6 and a pressure gauge 12 provided on the guide pipe 6.

[0037] In this embodiment, the above-mentioned maintenance mechanism is used to maintain the suspended matter filter in the impurity precipitation tank 1. When the pressure in the diversion pipe 6 decreases and is lower than the preset value, it indicates that the suspended matter filter is heavily clogged and should be cleaned in time. During maintenance, the second control valve 11 and the first control valve 10 can be closed to enter the filter for cleaning.

[0038] Please refer to Figure 1-Figure 4 In some implementations of the present embodiment, a self-cleaning pipe 13 is provided on the impurity precipitation tank 1 , the self-cleaning pipe 13 is connected to the diversion pipe 6 , and a third control valve 14 is connected in series to the self-cleaning pipe 13 .

[0039] In this embodiment, the self-cleaning pipe 13 is used to inject clean high-pressure water into the guide pipe 6, and is used to output water from the inside of the filter cartridge 701 to reversely clear the first through hole 8 and the second through hole 9, flush out the suspended impurities in the first through hole 8 and the second through hole 9, and then output them through the sewage pipe, which can greatly improve the convenience of cleaning.

[0040] In this embodiment, the third control valve 14 is used to control the opening and closing of the self-cleaning pipe 13, thereby controlling the sewage from entering the clean water pipe.

[0041] Please refer to Figure 1-Figure 4 In some implementations of the present embodiment, the mouth cover of the impurity precipitation tank 1 is provided with a cover body 15 , and a handle 16 is provided on the cover body 15 .

[0042] In this embodiment, the cover 15 is used to enclose the impurity sedimentation tank 1 into a closed cavity, which is convenient for sedimentation and filtration inside and prevents external impurities from entering and internal water from splashing out.

[0043] Furthermore, the handle 16 is used by the operator to remove the cover 15 through mechanical equipment to clean the impurity sedimentation tank 1 and the suspended matter filter element, thereby improving the sewage cleaning efficiency.

[0044] Please refer to Figure 1-Figure 4 In some implementations of this embodiment, a conical guide hopper 17 is provided at the bottom of the impurity precipitation tank 1 , and the sewage discharge pipe is located at the output end of the conical guide hopper 17 .

[0045] In this embodiment, the design of the conical guide hopper is conducive to the flow of materials. Its large inclination angle can ensure that the materials have good fluidity and can smoothly flow from high to low, reducing the possibility of blockage and retention.

[0046] Embodiment 2:

[0047] Please refer to Figure 5 This embodiment provides a sewage treatment system, including at least two sewage treatment tanks, and adjacent sewage treatment tanks are connected through an inlet pipe 3 and a drainage pipe 4.

[0048] In this embodiment, by connecting the two sewage treatment tanks end to end, the drainage pipe 4 of the first sewage treatment tank is connected to the liquid inlet pipe 3 of the second sewage treatment tank, the first sewage treatment tank is used to pre-treat the sewage, and then the water treated by the first sewage treatment tank is transported to the second sewage treatment tank through the drainage pipe 4, and the sewage can be post-treated. When the sewage treatment tanks are installed, the apertures of the suspended matter filters of the first sewage treatment tank and the second sewage treatment tank are adjusted to be smaller, thereby continuously improving the accuracy of water purification.

[0049] The above description is only the preferred embodiment of the present application and is not intended to limit the present application.
